The value of C-reactive protein, leucocytes and vital signs in detecting major complications after oncological colorectal surgery. Langenbecks Arch Surg 2024; 409:76. [PMID: 38409295 PMCID: PMC10896856 DOI: 10.1007/s00423-024-03266-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 02/19/2024] [Indexed: 02/28/2024]
Abstract
PURPOSE To assess the association of postoperative C-reactive protein (CRP), leucocytes and vital signs in the first three postoperative days (PODs) with major complications after oncological colorectal resections in a tertiary referral centre for colorectal cancer in The Netherlands. METHODS A retrospective cohort study, including 594 consecutive patients who underwent an oncological colorectal resection at Maastricht University Medical Centre between January 2016 and December 2020. Descriptive analyses of patient characteristics were performed. Logistic regression models were used to assess associations of leucocytes, CRP and Modified Early Warning Score (MEWS) at PODs 1-3 with major complications. Receiver operating characteristic curve analyses were used to establish cut-off values for CRP. RESULTS A total of 364 (61.3%) patients have recovered without any postoperative complications, 134 (22.6%) patients have encountered minor complications and 96 (16.2%) developed major complications. CRP levels reached their peak on POD 2, with a mean value of 155 mg/L. This peak was significantly higher in patients with more advanced stages of disease and patients undergoing open procedures, regardless of complications. A cut-off value of 170 mg/L was established for CRP on POD 2 and 152 mg/L on POD 3. Leucocytes and MEWS also demonstrated a peak on POD 2 for patients with major complications. CONCLUSIONS Statistically significant associations were found for CRP, Δ CRP, Δ leucocytes and MEWS with major complications on POD 2. Patients with CRP levels ≥ 170 mg/L on POD 2 should be carefully evaluated, as this may indicate an increased risk of developing major complications.

The Role of Nonmetastatic Lymph Nodes in the Survival of Colorectal Cancer: A Systematic Review. ANNALS OF SURGERY OPEN 2023; 4:e336. [PMID: 38144501 PMCID: PMC10735087 DOI: 10.1097/as9.0000000000000336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 08/11/2023] [Indexed: 12/26/2023] Open
Abstract
Objective In this review, we aim to provide an overview of literature on lymph node (LN) histomorphological features and their relationship with the prognosis in colorectal cancer (CRC). Background Lymph nodes play a crucial role in the treatment and prognosis of CRC. The presence of LN metastases considerably worsens the prognosis in CRC patients. Literature has shown that the total number of LNs and the number negative LNs (LNnegs) has prognostic value in CRC patients. In esophageal carcinoma, LN size seems to be surrogate of the host antitumor response and a potentially clinically useful new prognostic biomarker for (y)pN0 esophageal carcinoma. Methods A comprehensive search was performed in Pubmed, Embase, Medline, CINAHL, and the Cochrane library in March 2021. The PRISMA guidelines were followed. Only studies focusing on histomorphological features and LN size and their relation to overall survival were selected. Results A total of 9 unique articles met all inclusion criteria and were therefore included in this systematic review. Six of these studies investigated HMF (eg, paracortical hyperplasia, germinal center predominance, and sinus histiocytosis) and 4 studies LNneg size and their relationship with overall survival. The presence of paracortical hyperplasia and an increased number of large LNnegs is related to a more favorable prognosis in CRC. Conclusion The results of this systematic review seem to support the hypothesis that there is a relationship between the host antitumor response reflected in different histomorphological reaction patterns visible in LNnegs and LNneg size related to survival in CRC patients.

Responsiveness of the Patient-Reported Outcome Measure-Haemorrhoidal Impact and Satisfaction Score in patients with haemorrhoidal disease. Colorectal Dis 2023; 25:1832-1838. [PMID: 37475163 DOI: 10.1111/codi.16668] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/30/2023] [Accepted: 06/01/2023] [Indexed: 07/22/2023]
Abstract
AIM In this study we aimed to assess the responsiveness of the symptom score of the recently developed Patient-Reported Outcome Measure-Haemorrhoidal Impact and Satisfaction Score (PROM-HISS). Furthermore, the minimally relevant difference (MRD) was determined. METHOD The responsiveness of PROM-HISS was tested using a criterion-based (i.e. anchor) and construct-based (i.e. hypotheses testing) approach. Patients with haemorrhoidal disease (HD) completed the PROM-HISS before and 1 week after treatment in hospital. A global self-assessment of change question (SCQ) was administered 1-week after treatment and functioned as the criterion. The following analyses were performed: (1) correlation between the PROM-HISS symptom score and the criterion (SCQ) and (2) hypotheses testing. The MRD was determined as change in symptoms of the subgroup reporting 'somewhat fewer complaints' on the SCQ. RESULTS Between February and August 2022, 94 patients with grade II-IV HD from three hospitals were included. The correlation between the SCQ and a change on the PROM-HISS symptom score was 0.595 indicating that an improvement on the SCQ corresponds to an improvement on the PROM-HISS symptom score. As hypothesized, the mean change in PROM-HISS scores was significantly different between subgroups of patients based on their SCQ responses. Patients reporting a small change in HD symptoms on the SCQ corresponded to a mean change of 0.3 on the PROM-HISS symptom score. CONCLUSION The PROM-HISS symptom score is a responsive instrument as it identifies change in HD symptoms because of treatment. The estimated MRD of 0.3 can be used to inform clinical research and practice.

The Relation of Lifestyle with Inflammation at the Time of Diagnosis in Patients with Colorectal Cancer. Cancers (Basel) 2023; 15:4307. [PMID: 37686583 PMCID: PMC10486596 DOI: 10.3390/cancers15174307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 08/24/2023] [Accepted: 08/27/2023] [Indexed: 09/10/2023] Open
Abstract
Colorectal cancer is one of the most common lifestyle-related types of cancer. The exact pathophysiologic mechanism in the relation between (visceral) adipose tissue, systemic inflammation and colorectal cancer remains unknown. This study aimed to assess the association of lifestyle with markers of systemic inflammation at the time of diagnosis in stage I-III colorectal cancer patients. Patients (n = 298) with stage I-III colorectal cancer from three Dutch hospitals were included at diagnosis. Several lifestyle-related variables (MUST nutritional status score, WCRF/AICR healthy lifestyle score, active smoking, alcohol consumption and BMI) and inflammatory markers (plasma levels of IL-6, IL-8, IL-10, TNFα and 'high sensitive' hsCRP) were measured at the time of diagnosis. Confounder-adjusted multivariable linear regression models were used to analyse how the lifestyle variables were associated with the inflammatory markers. Statistically significant associations were found between a better WCRF/AICR lifestyle score and lower levels of IL-6 and hsCRP. A medium and high risk of malnutrition according to the MUST score was associated with elevated levels of both IL-8 and hsCRP. An overall unhealthier lifestyle indicated by a lower WCRF/AICR lifestyle score and a higher risk of malnutrition according to the MUST score at the time of diagnosis was associated with elevated levels of inflammatory markers. These findings can contribute to formulating lifestyle advice to improve treatment outcomes and prognosis in patients having CRC in the future.

English translation and cross-cultural validation of the patient-reported outcome measurement-haemorrhoidal impact and satisfaction score (PROM-HISS). Colorectal Dis 2023; 25:1671-1678. [PMID: 37431983 DOI: 10.1111/codi.16650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 05/28/2023] [Indexed: 07/12/2023]
Abstract
AIM The aim of this study was to translate the Dutch patient-reported outcome measure-haemorrhoidal impact and satisfaction score (PROM-HISS) to English and perform a cross-cultural validation. METHOD The ISPOR good practice guidelines for the cross-cultural validation of PROMs were followed and included two steps: (1) Two forward and two backward translations. The forward translation concerned the translation from the source language (Dutch) to the target language (English), performed by two independent English speakers, one medical doctor and one nonmedical. Subsequently, a discussion about discrepancies in the reconciled version was performed by a stakeholder group. (2) Cognitive interviews were held with patients with haemorrhoidal disease (HD), probing the comprehensibility and comprehensiveness of the PROM-HISS. RESULTS Discrepancies in the reconciled forward translation concerned the terminology of HD symptoms. Furthermore, special attention was paid to the response options, ranging from "not at all", indicating minor symptoms, to "a lot", implying many symptoms. Consensus among the stakeholder group about the final version of the translated PROM-HISS was reached. Interviews were conducted with 10 native English-speaking HD patients (30% female), with a mean age of 44 years (24-83) and primarily diagnosed with grade II HD (80%). The mean time to complete the PROM-HISS was 1 min 43 s. Patients showed a good understanding of the questions and response options, found all items relevant and did not miss important symptoms or topics. CONCLUSION The translated English language PROM-HISS is a valid tool to assess symptoms of HD, its impact on daily activities and patient satisfaction with HD treatment.

Replacement Adaptor 09106 for patients with a dynamic graciloplasty or patients with sacral neuromodulation and abdominal implantable pulse generators: a retrospective, single centre, Stage 2a/2b development IDEAL case series. Colorectal Dis 2023; 25:150-155. [PMID: 36226480 PMCID: PMC10091937 DOI: 10.1111/codi.16370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 08/26/2022] [Accepted: 10/01/2022] [Indexed: 02/02/2023]
Abstract
AIM Due to the introduction of a new implantable pulse generator (IPG), the Interstim II, patients with either a dynamic graciloplasty or an abdominally placed IPG for sacral neuromodulation could not undergo surgery to replace their IPG in the case of end of battery life. For these patients, the Medtronic Replacement Adaptor 09106 was created. This retrospective case series aims to study safety and feasibility of the Medtronic Replacement Adaptor 09106 in patients with abdominally placed IPGs. METHODS Seventeen patients (11 women, six men) received a replacement adaptor with a follow-up of 6 months. Outcome measures consisted of a bowel habit diary. Adverse events were classified using the Clavien-Dindo classification. RESULTS Outcome measures in the bowel habit diaries after replacement (feasibility) did not differ significantly from outcome measures before replacement. Adverse events occurred in four out of 17 patients (24%): two patients initially showed pocket site pain (Clavien-Dindo Grade I), which resolved without intervention. One patient suffered from poor wound closure (Clavien-Dindo Grade II) and one patient had persisting pocket pain (Clavien-Dindo Grade IIIa) for which a pocket revision was performed. Statistical analyses were performed making paired comparisons using a Wilcoxon signed rank test. CONCLUSION The Medtronic Replacement Adaptor 09106 is a valuable option for patients with dynamic graciloplasty or sacral neuromodulation and abdominal IPG and has complication rates similar to replacement of the Interstim without Replacement Adaptor 09106.

Guideline for the diagnosis and treatment of Faecal Incontinence-A UEG/ESCP/ESNM/ESPCG collaboration. United European Gastroenterol J 2022; 10:251-286. [PMID: 35303758 PMCID: PMC9004250 DOI: 10.1002/ueg2.12213] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 02/02/2022] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION The goal of this project was to create an up-to-date joint European clinical practice guideline for the diagnosis and treatment of faecal incontinence (FI), using the best available evidence. These guidelines are intended to help guide all medical professionals treating adult patients with FI (e.g., general practitioners, surgeons, gastroenterologists, other healthcare workers) and any patients who are interested in information regarding the diagnosis and management of FI. METHODS These guidelines have been created in cooperation with members from the United European Gastroenterology (UEG), European Society of Coloproctology (ESCP), European Society of Neurogastroenterology and Motility (ESNM) and the European Society for Primary Care Gastroenterology (ESPCG). These members made up the guideline development group (GDG). Additionally, a patient advisory board (PAB) was created to reflect and comment on the draft guidelines from a patient perspective. Relevant review questions were established by the GDG along with a set of outcomes most important for decision making. A systematic literature search was performed using these review questions and outcomes as a framework. For each predefined review question, the study or studies with the highest level of study design were included. If evidence of a higher-level study design was available, no lower level of evidence was sought or included. Data from the studies were extracted by two reviewers for each predefined important outcome within each review question. Where possible, forest plots were created. After summarising the results for each review question, a systematic quality assessment using the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) approach was performed. For each review question, we assessed the quality of evidence for every predetermined important outcome. After evidence review and quality assessment were completed, recommendations could be formulated. The wording used for each recommendation was dependent on the level of quality of evidence. Lower levels of evidence resulted in weaker recommendations and higher levels of evidence resulted in stronger recommendations. Recommendations were discussed within the GDG to reach consensus. RESULTS These guidelines contain 45 recommendations on the classification, diagnosis and management of FI in adult patients. CONCLUSION These multidisciplinary European guidelines provide an up-to-date comprehensive evidence-based framework with recommendations on the diagnosis and management of adult patients who suffer from FI.

Burden of disease experienced by patients following a watch-and-wait policy for locally advanced rectal cancer: A qualitative study. Colorectal Dis 2021; 23:2870-2878. [PMID: 34314550 PMCID: PMC9291314 DOI: 10.1111/codi.15838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 05/25/2021] [Accepted: 06/16/2021] [Indexed: 02/08/2023]
Abstract
AIM Patient-reported outcome measures (PROMs) are increasingly being used in routine cancer care to evaluate treatment and monitor symptoms, function and other aspects of quality of life (QoL). There is no suitable PROM for rectal cancer patients following a watch-and-wait (W&W) programme. Insight into patient experiences with this programme is an essential step in the development of a PROM. The aim of this qualitative study was to provide insights into the most important functional outcomes and QoL features experienced by patients during our W&W programme. METHOD Patients with locally advanced rectal cancer who are enrolled in the W&W programme in the Netherlands were interviewed by telephone using a semistructured interview guide. All interviews were digitally audio-recorded, transcribed verbatim and coded. A thematic approach was used to analyse the data and identify themes and subthemes of importance to patients. RESULTS Eighteen patients were interviewed (78% male, mean age 68 years, range 52-83 years). Physical complaints after treatment were present, most notably gastrointestinal problems, neuropathy and fatigue. Furthermore, patients were anxious about a possible recurrence, had a fear of surgery or a stoma, or were experiencing a general feeling of apprehension in daily life. Many patients had different coping mechanisms, such as acceptance, and there were few limitations in daily life. CONCLUSION We identified important functional outcomes, such as gastrointestinal complaints, fatigue and neuropathy, in patients who were enrolled in this W&W programme. Furthermore, an emotional burden and unmet needs were reported by these patients. These findings can be used to improve clinical practice and inform the development of a PROM.

Cross-Sectional Associations between Dietary Daily Nicotinamide Intake and Patient-Reported Outcomes in Colorectal Cancer Survivors, 2 to 10 Years Post-Diagnosis. Nutrients 2021; 13:nu13113707. [PMID: 34835963 PMCID: PMC8624000 DOI: 10.3390/nu13113707] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 10/19/2021] [Accepted: 10/20/2021] [Indexed: 12/18/2022] Open
Abstract
Supplementation with nicotinamide adenine dinucleotide (NAD+) precursors including dietary nicotinamide has been found to boost tissue NAD+ levels and ameliorate oxidative stress-induced damage that contributes to aging and aging-related diseases. The association between dietary NAD+ precursors and patient-reported health-related outcomes in cancer survivors has not been investigated. This study aimed to determine associations of dietary nicotinamide intake with different patient-reported outcomes in colorectal cancer survivors, 2 to 10 years post-diagnosis. A total of 145 eligible participants were recruited into this cross-sectional study. Dietary nicotinamide intake level was calculated based on data from 7-day food diaries. Fatigue was assessed with the Checklist Individual Strength (CIS), which is a subscale of the cancer-specific European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC), and anxiety and depression were assessed with Hospital Anxiety and Depression Scale (HADS). Oxidative stress marker serum protein carbonyl contents and serum NAD+ levels were measured. A hierarchical linear regression model with confounder adjustment was performed to analyze the association of nicotinamide intake, serum protein carbonyl contents, and NAD+ levels with patient-reported outcomes. The median values of daily nicotinamide intake for male and female participants were 19.1 and 14.4 mg, respectively. Daily dietary nicotinamide intake was associated with a lower level of fatigue (β: -14.85 (-28.14, -1.56)) and a lower level of anxiety and depression (β: -4.69 (-8.55, -0.83)). Subgroup analyses by sex showed that a beneficial association between nicotinamide intake and patient-reported outcomes was mainly found in men. To conclude, our findings suggested that higher dietary NAD+ precursor nicotinamide intake was cross-sectionally associated with less patient-reported outcomes in CRC survivors.

Making Use of Patient-Reported Outcome Measures for Haemorrhoidal Disease in Clinical Practice: A Perspective. Front Surg 2021; 8:728532. [PMID: 34513917 PMCID: PMC8424037 DOI: 10.3389/fsurg.2021.728532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Accepted: 07/26/2021] [Indexed: 11/14/2022] Open
Abstract
Haemorrhoidal disease (HD) affects millions of people around the world and for most it is a recurring problem. Increasingly, clinicians broaden their focus on the patient's experiences with haemorrhoidal symptoms, including their impact on daily life. The patient's experience can be assessed using a patient-reported outcome measure (PROM). A PROM facilitates a deeper understanding of the disease-burden and allows a clinician to obtain information directly from the patients about their experiences with the ailment. Over the last years, PROMs have shown their additional role to traditional outcomes for several diseases and have earned their place in the daily consultation room. In order to improve and personalize the treatment of HD, we endorse the use of validated PROMs in clinical care.

Patient-reported outcome measures in oncology: a qualitative study of the healthcare professional's perspective. Support Care Cancer 2021; 29:5253-5261. [PMID: 33655412 PMCID: PMC8295145 DOI: 10.1007/s00520-021-06052-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 02/07/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND In the last decades, the number of cancer survivors has increased significantly due to improved treatment and better detection of recurrence. This increased survival redirects the scope from survival towards optimising functional outcomes and improving health-related quality of life (HRQol). Functional and HRQoL outcomes can be assessed with patient-reported outcome measures (PROMs). However, the use of PROMs in daily oncological care is not common. This qualitative study investigates the barriers and facilitators of PROM use in an oncological setting, from the perspective of the healthcare professionals (HCPs). METHODS Individual semi-structured interviews were conducted among Dutch oncological HCPs. Barriers and facilitators of PROM implementation were identified on various levels of the healthcare system (i.e. level of the patient, individual professional, medical team, and healthcare organisation). Interviews were audio recorded and transcribed verbatim. Transcripts were manually analysed by two independent reviewers using a thematic approach. Identified barriers and facilitators were categorised into Grol and Wensing's framework for changing healthcare practice. RESULTS Nineteen oncological HCPs working in academic and non-academic hospitals were interviewed. Barriers for PROM implementation were lack of good IT support, lack of knowledge on how to use PROMs, lack of time to complete and interpret PROMs, and a high administrative burden. PROM implementation can be facilitated by providing clear guidance regarding PROM interpretation, evidence that PROMs can save time, and stimulating multidisciplinary teamwork. CONCLUSION From a HCP point of view, adequately functioning IT technology, sufficient knowledge on PROMs, and dedicated time during the consultation are essential for successful implementation of PROMs in oncological care. Additional local context-specific factors need to be thoroughly addressed.

Levels of Inflammation Markers Are Associated with the Risk of Recurrence and All-Cause Mortality in Patients with Colorectal Cancer. Cancer Epidemiol Biomarkers Prev 2021; 30:1089-1099. [PMID: 33771850 DOI: 10.1158/1055-9965.epi-20-1752] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 02/19/2021] [Accepted: 03/16/2021] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND We investigated whether preoperative and postoperative levels of inflammation markers, which have mechanistically been linked to colorectal cancer progression, were associated with recurrence and all-cause mortality in patients with colorectal cancer. METHODS Data of two prospective cohort studies were used. For the current analysis, patients with stage I to III colorectal cancer were considered. Data on inflammation [IL6, IL8, IL10, TNFα, high-sensitivity C-reactive protein (hsCRP), and a combined inflammatory z-score] were available for 747 patients before surgery and for 614 patients after surgery. The associations between inflammation marker levels and colorectal cancer recurrence and all-cause mortality were examined using multivariable Cox proportional hazard regression models, considering patient characteristics and clinical and lifestyle factors. RESULTS Higher preoperative and postoperative hsCRP levels were associated with a higher risk of recurrence [HRper doubling (95% CI), 1.15 (1.02-1.30) and 1.34 (1.16-1.55)] and all-cause mortality [HRper doubling (95% CI) 1.13 (1.01-1.28) and 1.15 (0.98-1.35)]. A doubling in IL8 levels (preoperative levels HR = 1.23; 95% CI, 1.00-1.53 and postoperative levels HR = 1.61; 95% CI, 1.23-2.12) and a higher combined inflammatory z-score (preoperative HRper doubling = 1.39; 95% CI, 1.03-1.89 and postoperative HRper doubling = 1.56; 95% CI, 1.06-2.28) were associated with a higher risk of all-cause mortality, but not recurrence. No associations between IL6, IL10, and TNFα and recurrence or all-cause mortality were observed. CONCLUSIONS Preoperative and postoperative levels of specific inflammation markers were associated with recurrence and/or all-cause mortality. IMPACT The complex role of inflammation in cancer recurrence merits further elucidation by investigating local inflammation at the tumor site.

Abstract
BACKGROUND Whether changes in 25 hydroxy vitamin D3 (25(OH)D3) levels after colorectal cancer diagnosis influence clinical outcomes is unclear. We investigated the association of trajectories of 25(OH)D3 levels with recurrence and all-cause mortality. METHODS In total, 679 patients were included in our data analyses. Trajectories of 25(OH)D3 levels were defined on the basis of vitamin D status at diagnosis, at 6 months, and 2 years after diagnosis. Observed trajectories of 25(OH)D3 levels were consistent deficient levels (20%), consistent sufficient levels (39%), increasing levels (20%), and a temporary drop in levels (13%). Associations of trajectories of 25(OH)D3 with recurrence and all-cause mortality were assessed using multivariable Cox proportional hazards regression models. RESULTS During a follow-up time of 2.2 years for recurrence and 3.5 years for all-cause mortality, 31 and 65 events occurred, respectively. No statistically significant associations were observed for vitamin D trajectories and the risk of recurrence. Patients who were consistently sufficient compared with patients who were consistently deficient had a lower risk of all-cause mortality [HR 0.39; 95% confidence interval (CI), 0.21-0.73]. The risk of all-cause mortality seems lower in patients with increasing levels or a temporary drop in levels (HR 0.54; 95% CI, 0.27-1.10 and HR 0.40 95% CI, 0.17-0.93) relative to patients with consistent deficient levels. CONCLUSIONS Patients with colorectal cancer following a trajectory characterized by sufficient levels of 25(OH)D3 2 years after diagnosis all appeared to have a lower risk of all-cause mortality compared with patients having consistent deficient levels. IMPACT Further studies should investigate how trajectories of 25(OH)D3 levels are associated with colorectal cancer recurrence.

Abstract
OBJECTIVE Conventional sacral neuromodulation (SNM) has shown to be an effective treatment for lower urinary tract and bowel dysfunction, but improvements of clinical outcome are still feasible. Currently, in preclinical research, new stimulation parameters are being investigated to achieve better and longer effects. This systematic review summarizes the status of SNM stimulation parameters and its effect on urinary tract and bowel dysfunction in preclinical research. MATERIALS AND METHODS The literature search was conducted using three databases: Ovid (Medline, Embase) and PubMed. Articles were included if they reported on stimulation parameters in animal studies for lower urinary tract or bowel dysfunction as a primary outcome. Methodological quality assessment was performed using the SYRCLE Risk of Bias (RoB) tool for animal studies. RESULTS Twenty-two articles were eligible for this systematic review and various aspects of stimulation parameters were included: frequency, intensity, pulse width, stimulation signal, timing of stimulation, and unilateral vs. bilateral stimulation. In general, all experimental studies reported an acute effect of SNM on urinary tract or bowel dysfunction, whereas at the same time, various stimulation settings were used. CONCLUSIONS The results of this systematic review indicate that SNM has a positive therapeutic effect on lower urinary tract and bowel dysfunction. Using low-frequency-SNM, high-frequency-SNM, bilateral SNM, and higher pulse widths showed beneficial effects on storage and evacuation dysfunction in animal studies. An increased variability of stimulation parameters may serve as a basis for future improvement of the effect of SNM in patients suffering from urinary tract or bowel dysfunction.

Prevention of intra-abdominal adhesions by a hyaluronic acid gel; an experimental study in rats. J Biomater Appl 2020; 35:887-897. [PMID: 32878535 DOI: 10.1177/0885328220954188] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/23/2022]
Abstract
BACKGROUND In 80% to 90% of the patients intra-abdominal adhesions occur after abdominal surgery, which can cause small-bowel obstruction, chronic abdominal pain, female infertility and difficulty during reoperation. A novel crosslinked hyaluronic acid gel is evaluated regarding its anti-adhesive capacities in an ischemic button model in rats. METHOD 51 adult, male Wistar rats from a registered breeder, received eight ischemic buttons each and were treated with hyaluronic acid gel (HA, HyaRegen©), hyaluronic acid carboxymethylcellulose (HA-CMC, Seprafilm©) or no anti-adhesive barrier. After 14 days, the animals were sacrificed and adhesions were scored macroscopically. The number of buttons and organs involved in adhesions were recorded. Per animal, one button with adhesions and one without adhesions was explanted for qPCR analysis. Mann-Whitney U, Fisher's exact and Wilcoxon signed rank test were used for data analysis. A p-value of 0.05 was considered significant. RESULTS Macroscopic evaluation of adhesion formation did not differ between the groups. The number of organs involved in adhesions in the HA gel group was significantly lower compared to HA-CMC (p = .041) and the control group (p = .012). A significantly, 1.36-fold higher clec10a (p = 0.25), 1.80-fold higher cd163 (p = 0.003) and 5.14-fold higher mmp1 expression (p = 0.028) was found in ischemic buttons with adhesions compared to buttons without adhesions. CONCLUSION HA gel application reduces the number of organs involved in adhesions in an ischemic button model, but no overall reduction in adhesion formation was encountered. Macrophage subtype 2 polarization and high mmp1 expression are associated with adhesion formation. Further investigation is needed in the exact pathophysiologic process of adhesion formation and the role of macrophage polarization.

Stimulation Parameters for Sacral Neuromodulation on Lower Urinary Tract and Bowel Dysfunction-Related Clinical Outcome: A Systematic Review. Neuromodulation 2020; 23:1082-1093. [PMID: 32830414 PMCID: PMC7818464 DOI: 10.1111/ner.13255] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 07/08/2020] [Accepted: 07/10/2020] [Indexed: 01/03/2023]
Abstract
Objective Sacral neuromodulation (SNM) has been used to treat patients with lower urinary tract dysfunction and bowel dysfunction for many years. Success rates vary between 50% and 80%, indicating that there is much room for improvement. Altering stimulation parameters may result in improved outcome. This paper reports a systematic review of the clinical efficacy of nonconventional stimulation parameters on urinary tract and bowel dysfunction. Materials and Methods Three databases were used for the literature search: Ovid (Medline, Embase) and PubMed. Papers were screened by two independent reviewers, who also extracted data from these papers. Clinical papers studying SNM stimulation parameters, that is, intermittent stimulation, frequency, pulse width, and amplitude, in urinary tract and bowel dysfunction were included. Quality of included papers was assessed using standardized guidelines. Results Out of 5659 screened papers, 17 papers, studying various stimulation parameters, were included. Overall quality of these papers differed greatly, as some showed no risk of bias, whereas others showed high risk of bias. Stimulation parameters included intermittent stimulation, frequency, pulse width, amplitude, and unilateral vs. bilateral stimulation. Especially high frequency SNM and either a narrow or wide pulse width seem to improve efficacy in patients with bowel dysfunction. Additionally, implementation of short cycling intervals is promising to improve quality of life for patients with urinary tract or bowel dysfunction. Conclusion The results of our systematic review indicate that stimulation parameters may improve efficacy of SNM in treatment of both urinary tract dysfunction and bowel dysfunction.

Longitudinal associations of light-intensity physical activity with quality of life, functioning and fatigue after colorectal cancer. Qual Life Res 2020; 29:2987-2998. [PMID: 32617891 PMCID: PMC7591443 DOI: 10.1007/s11136-020-02566-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/19/2020] [Indexed: 11/26/2022]
Abstract
Purpose Evidence from cross-sectional studies suggests that higher levels of light-intensity physical activity (LPA) are associated with better health-related quality of life (HRQoL) in colorectal cancer (CRC) survivors. However, these associations have not been investigated in longitudinal studies that provide the opportunity to analyse how within-individual changes in LPA affect HRQoL. We investigated longitudinal associations of LPA with HRQoL outcomes in CRC survivors, from 6 weeks to 2 years post-treatment. Methods Data were used of a prospective cohort study among 325 stage I–III CRC survivors (67% men, mean age: 67 years), recruited between 2012 and 2016. Validated questionnaires were used to assess hours/week of LPA (SQUASH) and HRQoL outcomes (EORTC QLQ-C30, Checklist Individual Strength) at 6 weeks, and 6, 12 and 24 months post-treatment. We applied linear mixed regression to analyse longitudinal confounder-adjusted associations of LPA with HRQoL. Results We observed statistically significant longitudinal associations between more LPA and better global quality of life and physical, role and social functioning, and less fatigue over time. Intra-individual analysis showed that within-person increases in LPA (per 8 h/week) were related to improved HRQoL, including better global quality of life (β = 1.67, 95% CI 0.71; 2.63; total range scale: 0–100) and less fatigue (β = − 1.22, 95% CI − 2.37; − 0.07; scale: 20–140). Stratified analyses indicated stronger associations among participants below the median of moderate-to-vigorous physical activity (MVPA) at diagnosis. Conclusion Higher levels of LPA were longitudinally associated with better HRQoL and less fatigue in CRC survivors up to two years post-treatment. Further prospective studies using accelerometer data are necessary to inform development of interventions targeting LPA.

European Society of ColoProctology: guideline for haemorrhoidal disease. Colorectal Dis 2020; 22:650-662. [PMID: 32067353 DOI: 10.1111/codi.14975] [Citation(s) in RCA: 67] [Impact Index Per Article: 16.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 01/03/2020] [Indexed: 12/15/2022]
Abstract
AIM The goal of this European Society of ColoProctology project was to establish a multidisciplinary, international guideline for haemorrhoidal disease (HD) and to provide guidance on the most effective (surgical) treatment for patients with HD. METHODS The development process consisted of six phases. In phase one we defined the scope of the guideline. The patient population included patients with all stages of haemorrhoids. The target group for the guideline was all practitioners treating patients with haemorrhoids and, in addition, healthcare workers and patients who desired information regarding the treatment management of HD. The guideline needed to address both the diagnosis of and the therapeutic modalities for HD. Phase two consisted of the compilation of the guideline development group (GDG). All clinical members needed to have affinity with the diagnosis and treatment of haemorrhoids. Further, attention was paid to the geographical distribution of the clinicians. Each GDG member identified at least one patient in their country who could read English to comment on the draft guideline. In phase three review questions were formulated, using a reversed process, starting with possible recommendations based on the GDG's knowledge. In phase four a literature search was performed in MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews. The search was focused on existing systematic reviews addressing each review question, supplemented by other studies published after the time frame covered by the systematic reviews. In phase five data of the included papers were extracted by the surgical resident (RT) and checked by the methodologist (JK) and the GDG. If needed, meta-analysis of the systematic reviews was updated by the surgical resident and the methodologist using Review Manager. During phase six the GDG members decided what recommendations could be made based on the evidence found in the literature using GRADE. RESULTS There were six sections: (i) symptoms, diagnosis and classification; (ii) basic treatment; (iii) outpatient procedures; (iv) surgical interventions; (v) special situations; (vi) other surgical techniques. Thirty-four recommendations were formulated. CONCLUSION This international, multidisciplinary guideline provides an up to date and evidence based summary of the current knowledge of the management of HD and may serve as a useful guide for patients and clinicians.

Chemotherapy and vitamin D supplement use are determinants of serum 25-hydroxyvitamin D levels during the first six months after colorectal cancer diagnosis. J Steroid Biochem Mol Biol 2020; 199:105577. [PMID: 31917319 DOI: 10.1016/j.jsbmb.2020.105577] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Revised: 12/19/2019] [Accepted: 01/03/2020] [Indexed: 12/14/2022]
Abstract
Vitamin D metabolites, including 25-hydroxyvitamin D3 (25(OH)D3), may inhibit colorectal cancer (CRC) progression. Here we investigated cross-sectional and longitudinal associations of demographic, lifestyle and clinical characteristics with 25(OH)D3 serum concentrations in CRC patients at diagnosis and six months later. In 1201 newly-diagnosed stage I-III CRC patients, 25(OH)D3 levels were analysed twice. Multivariable linear regression was used to assess demographic, lifestyle and clinical determinants of 25(OH)D3 levels at diagnosis and six months later. Linear mixed models were used to assess characteristics associated with changes in 25(OH)D3 levels over time. Results of our study showed that vitamin D intake from diet or supplements, use of calcium supplements, BMI and disease stage were associated with 25(OH)D3 levels at both time points. Six months after diagnosis, gender and having received chemo- and/or radiotherapy were also associated with 25(OH)D3 levels. A stronger decrease in 25(OH)D3 levels was observed in patients who underwent chemotherapy, compared to surgery only (β-6.9 nmol/L 95 %CI -9.8; -4.0). Levels of 25(OH)D3 levels increased in patients using vitamin D supplements compared to non-users (β 4.0 nmol/L 95 %CI 1.2; 6.8). In conclusion, vitamin D supplement use and treatment appear to be important determinants of 25(OH)D3 levels during the first six months after CRC diagnosis, although the difference in 25(OH)D3 levels was minor.

Importance of patient reported and clinical outcomes for patients with locally advanced rectal cancer and their treating physicians. Do clinicians know what patients want? Eur J Surg Oncol 2020; 46:1634-1641.

Abstract
INTRODUCTION Several factors are included in decision making for treatment of patients with locally advanced rectal cancer, including a trade-off between risks and gains of both clinical and functional outcomes. However, it is largely unknown which outcomes are most important to patients and whether this differs between patients and clinicians. METHODS Both clinicians and patients treated for locally advanced rectal cancer were invited to fill out an online questionnaire, including a choice-based conjoint experiment. Participants were presented 14 comparisons of two hypothetical case presentations, characterized by different treatments and outcomes of care (6 attributes) and were asked to select the case with the best outcome at that moment. Hierarchical Bayes Estimation was used to calculate the relative importance (RI) of each of the six attributes. RESULTS In total, 94 patients and 128 clinicians completed the questionnaire. For patients, avoiding surgery with permanent stoma was most important (RI 24.4, 95%CI 21.88-26.87) and a 2-year difference in disease-free survival was least important (RI 5.6, 95%CI 4.9-6.2). Clinicians assigned highest importance to avoiding severe and daily worries about cancer recurrence (RI 30.7, 95%CI 29.1-32.4), while this was ranked 4th by patients (RI 17.9, 95%CI 16.5-19.4, p < 0.001). CONCLUSION When confronted with different outcomes within one case description, patients find the duration of disease free survival the least important. In addition, considerable differences were found between the importance assigned by patients and clinicians to clinical and functional outcomes, most notably in avoiding surgery with permanent stoma and worries about recurrence.

Fasciocutaneous anterolateral thigh flaps for complex abdominal wall reconstruction after resection of enterocutaneous fistulas and the role of indocyanine green angiography: a pilot study. Hernia 2020; 25:321-329. [PMID: 32219573 PMCID: PMC8055571 DOI: 10.1007/s10029-020-02167-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Accepted: 02/27/2020] [Indexed: 02/05/2023]
Abstract
Purpose No previous study reported the use of a fasciocutaneous anterolateral thigh (ALT) flap combined with a biological mesh for abdominal wall reconstruction (AWR) after enterocutaneous fistula (ECF) in a single-staged procedure and the use of Indocyanine Green Angiography (ICGA) intraoperatively. The purpose of this study was to determine the feasibility and safety of this procedure and to examine the added value of ICGA in minimizing postoperative complications. Methods A single-institution review of a prospectively maintained database was conducted at Maastricht University Medical Center. To evaluate the feasibility and safety of this procedure, early (≤ 30 days) and late (> 30 days) postoperative complications were assessed. ECF recurrence was considered the primary outcome. To examine the added value of ICGA, complications in the ICGA group and the non-ICGA group were compared descriptively. Results Ten consecutive patients, with a mean age of 66.7 years, underwent a single-staged AWR with fasciocutaneous ALT flaps. Mean follow-up was 17.4 months (4.3–28.2). Two early ECF recurrences were observed. Both restored without the need for reoperation. A lower rate of early complications was observed in the ICGA group compared to the non-ICGA group. Conclusion The combination of a biological mesh and fasciocutaneous ALT flap is feasible and safe in AWR after ECF repair in a single-staged approach, with an acceptable complication rate in a cohort of complex patients operated in a dedicated center. ECF closure was achieved in all patients. ICGA seems to be of great added value in minimizing postoperative complications during AWR.

Abstract
PURPOSE Cryptoglandular anal fistula is a disorder with an incidence of around 1 per 5,000 people per year in European countries. Many studies have been conducted to evaluate the effectiveness of interventions for anal fistula. However, there is considerable heterogeneity in the outcomes assessed and reported in these studies. This limits research quality and complicates evidence synthesis. A solution for heterogeneity in outcome reporting is the development of a Core Outcome Set (COS). This paper describes the protocol for the development of a European COS for Anal Fistula (AFCOS). METHODS The first step will be a systematic review of the literature to identify potential outcomes that may be included in the COS. Patient interviews will be conducted in The United Kingdom and The Netherlands to ensure that both clinician-important and patient-important outcomes are captured. The outcomes will be categorized using the COMET taxonomy and taken forward to a Delphi consensus exercise. In up to three web-based Delphi surveys the outcomes will be prioritized by patients, clinicians (surgeons, gastroenterologists, and radiologists), and (clinical) researchers. The responses will be summarized and reported anonymously in subsequent round(s) facilitating convergence to a consensus opinion. The final COS will be decided during a face-to-face consensus meeting with patients, clinicians, and (clinical) researchers. DISCUSSION This study protocol describes the development of a European COS for anal fistula to improve research quality, evidence synthesis, and patient care.

Abstract
BACKGROUND Success rates of up to 80% have been reported for the SNM screening period in the treatment of fecal incontinence (FI). Some patients who have an unsuccessful index implantation are successfully treated with SNM after a lead revision. There is a lack of studies comparing the outcomes of successful index implantations and successful lead revision. Therefore, the results of index implantations were compared with lead revisions in a single-center cohort. METHODS Patients treated with SNM for FI between 2008 and 2016 were retrospectively reviewed. Patients with a successful index implantation were compared with patients who underwent lead revision after SNM screening. Primary outcome was a decrease in episodes of fecal incontinence of ≥ 50% documented by a 3-week bowel habit diary. RESULTS Two hundred sixty-one patients (232 index group, 29 revision group) were eligible for SNM. Two hundred thirty-one patients (208 index group, 23 revision group) received permanent SNM. Follow-up was 68.8 months for the index group and 62.2 months for the revision group. The number of episodes of FI decreased from 20.6 (SD 19.3) to 3.4 (SD 4.2) in the index group and from 12.6 (SD 5.8) to 2.0 (SD 2.3) in the revision group. This effect was maintained up to 5 and 2 years in the index and revision group, respectively. Adverse events such as loss of efficacy which required surgical intervention did not differ between the two groups. CONCLUSION Lead revision during the test phase is a valid option in patients with FI treated by SNM who suffer from loss of efficacy of the index electrode.

Abstract
Background Chronic postoperative pain occurs in up to 21·7 per cent of patients undergoing open inguinal hernia repair. Several mesh fixation techniques using glue or self‐gripping meshes have been developed to reduce postoperative pain. The aim of this meta‐analysis was to evaluate RCTs comparing adhesional/self‐gripping and sutured single‐layer open mesh fixations in the repair of inguinal herniation, with postoperative pain as endpoint. Methods PubMed, Embase and Cochrane CENTRAL databases were searched systematically for RCTs according to the PRISMA guidelines; the study was registered at PROSPERO (CRD42017056373). Different fixation methods were analysed. The primary outcome, chronic pain, was defined as a postoperative visual analogue scale (VAS) score of at least 3 at 12 months. Secondary outcomes were mean VAS score at 1 week and at 1 month after surgery. Results Twenty‐three studies including 5190 patients were included in the meta‐analysis. Adhesional (self‐adhering or glued) or self‐gripping fixation methods were associated with a significantly lower VAS score at 1 week (mean difference –0·49, 95 per cent c.i. ‐0·81 to –0·17; P = 0·003) and at 1 month (mean difference –0·31, –0·58 to –0·04; P = 0·02) after surgery than suture fixation, but the incidence of chronic pain after 12 months was similar in the two groups (odds ratio 0·70, 95 per cent c.i. 0·30 to 1·66). Differences in recurrences and complications between groups did not reach statistical significance. Conclusion There was no difference in the incidence of chronic pain 12 months after different mesh repair fixation techniques despite significant reductions in short‐term postoperative pain favouring a non‐sutured technique. There were no differences in recurrence rates or in rates of other complications at 1 year.

Abstract
AIM There is considerable heterogeneity in outcomes in studies reporting on the treatment of haemorrhoidal disease (HD). The aim of this study was to develop a Core Outcome Set (COS) for HD in cooperation with the European Society of Coloproctology. METHOD A Delphi study was performed according to the Outcome Measures in Rheumatology (OMERACT) methodology. In total 38 healthcare professionals and 30 patients were invited to the panel. Previously, 10 outcome domains and 59 outcomes were identified through a systematic literature review. In this study, these domains and outcomes were formed into one questionnaire for healthcare professionals and a separate questionnaire for patients. Sequential questionnaire rounds prioritizing the domains and outcomes were conducted. Panel members were asked to rate the appropriateness of each domain and outcome on a nine-point Likert scale. During a face-to-face meeting, healthcare professionals agreed on the primary and secondary end-points of the COS for HD. Finally, a short survey was sent to the healthcare professionals in order to reach consensus on how the chosen end-points should be assessed and at which time points. RESULTS The response rate in questionnaire round 1 for healthcare professionals was 44.7% (n = 17). Sixteen out of 17 healthcare professionals also completed the questionnaire in round 2. The response rate for the patient questionnaire was 60% (n = 18). Seventeen healthcare professionals participated in the face-to-face meeting. The questionnaire rounds did not result in a clear-cut selection of primary and secondary end-points. Most domains and outcomes were considered important, and only three outcomes were excluded. During the face-to-face meeting, agreement was reached to select the domain 'symptoms' as primary end-point, and 'complications', 'recurrence' and 'patient satisfaction' as secondary end-points in the COS for HD. Furthermore, consensus was reached that the domain 'symptoms' should be a patient reported outcome measure and should include the outcomes 'pain' and 'prolapse', 'itching', 'soiling' and 'blood loss'. The domain 'complications' should include the outcomes 'incontinence', 'abscess', 'urinary retention', 'anal stenosis' and 'fistula'. Consensus was reached to use 'reappearance of initial symptoms' as reported by the patient to define recurrence. During an additional short survey, consensus was reached that 'incontinence' should be assessed by the Wexner Fecal Incontinence Score, 'abscess' by physical examination, 'urinary retention' by ultrasonography, 'anal stenosis' by physical examination, and 'fistula' by physical examination and MR imaging if inconclusive. During follow-up, the outcome 'symptoms' should be assessed at baseline, 7 days, 6 weeks and 1 year post-procedure. The outcomes 'abscess' and 'urinary retention' should be assessed 7 days post-procedure and 'incontinence', 'anal stenosis' and 'fistula' 1 year post-procedure. CONCLUSIONS We developed the first European Society of Coloproctology COS for HD based on an international Delphi study among healthcare professionals. The next step is to incorporate the patients' perspective in the COS. Use of this COS may improve the quality and uniformity of future research and enhance the analysis of evidence.

Abstract
PURPOSE The aim of the study was to assess the long-term outcome of a Malone antegrade continence enema (MACE) procedure for fecal incontinence or constipation in adults. METHODS This retrospective single-center study assessed the long-term outcome and quality of life (QoL) of patients who underwent a MACE procedure between 2005 and 2014 at the Maastricht University Medical Centre. Success rate was quantified by using Malone's continence scale. Quality of life was assessed by validated questionnaires covering general quality of life (SF-36 and Karnofsky scale), current pain level (visual analog scale), fecal incontinence (Vaizey incontinence survey), or constipation (Cleveland Clinic Constipation Score). RESULTS Based on patients' records, 22 out of 30 patients (73%; 95% CI 54-87%) were still using their MACE. Mean follow-up was 43 months (SD 25.9) since time of surgery. According to the Malone continence scale, the overall success rate was 37% (95% CI 20.0-53.3). Nine patients developed a postoperative complication. Eighteen out of 22 patients (13 with constipation and 5 with fecal incontinence) returned the QoL questionnaires (82% response rate). Long-term quality of life of patients with a MACE did not differ from the general Dutch population. CONCLUSIONS In our cohort of patients with fecal incontinence or constipation, MACE resulted in a disappointed overall success rate of 37%. However, it may be indicated in patients who do not prefer more invasive surgical procedures or a definite stoma. The success and morbidity rate should be thoroughly discussed with the patients preoperatively.

Abstract
AIM The aim of this study was to validate the Dutch translation of the low anterior resection syndrome (LARS) score in a population of Dutch rectal cancer patients. METHOD Patients who underwent surgery for rectal cancer received the LARS score questionnaire, a single quality of life (QoL) category question and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire. A subgroup of patients received the LARS score twice to assess the test-retest reliability. RESULTS A total of 165 patients were included in the analysis, identified in six Dutch centres. The response rate was 62.0%. The percentage of patients who reported 'major LARS' was 59.4%. There was a high proportion of patients with a perfect or moderate fit between the QoL category question and the LARS score, showing a good convergent validity. The LARS score was able to discriminate between patients with or without neoadjuvant radiotherapy (P = 0.003), between total and partial mesorectal excision (P = 0.008) and between age groups (P = 0.039). There was a statistically significant association between a higher LARS score and an impaired function on the global QoL subscale and the physical, role, emotional and social functioning subscales of the EORTC QLQ-C30 questionnaire. The test-retest reliability of the LARS score was good, with an interclass correlation coefficient of 0.79. CONCLUSION The good psychometric properties of the Dutch version of the LARS score are comparable overall to the earlier validations in other countries. Therefore, the Dutch translation can be considered to be a valid tool for assessing LARS in Dutch rectal cancer patients.

Abstract
BACKGROUND Fecal incontinence (FI) has a multifactorial pathophysiology with a severe social impact. The most common cause for FI is pudendal nerve damage, which mostly occurs in women during or after labor. A better understanding of the pathophysiology is required to optimize treatment of FI. In this study, we evaluate the use of a novel pelvic nerve damage rat model of FI. METHODS This new model simulates the forces on the pelvic floor during labor by prolonged transvaginal, retro-uterine intrapelvic balloon distention in female rats. Number of fecal pellets produced per day and defecation pattern was compared between the experimental and control group for 2 weeks. The cages of the rats were divided in food, nesting and latrine areas to evaluate changes in defecation pattern. The FI Index (FII) was calculated to assess the ratio of fecal pellets between the non-latrine areas and the total number of pellets. A higher score represents more random distribution of feces outside the latrine area. RESULTS Total number of fecal pellets was higher in the experimental group as compared with the controls. In both groups most fecal pellets were deposited in the nesting area, which is closest to the food area. The experimental group deposited more fecal pellets in the latrine area and had a lower FII indicating less random distribution of feces outside the latrine area. CONCLUSION Transvaginal, retro-uterine intrapelvic balloon distention is a safe and feasible animal model simulating the human physiologic impact of labor by downwards pressure on the pelvic floor.

Long-term outcome of intractable constipation treated by sacral neuromodulation: a comparison between children and adults. Colorectal Dis 2018; 20:134-143. [PMID: 28782277 DOI: 10.1111/codi.13837] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2017] [Accepted: 07/25/2017] [Indexed: 12/18/2022]
Abstract
AIM Sacral neuromodulation (SNM) is a minimally invasive therapy for functional constipation (FC) and is most often used to treat adults. Recent studies suggest that SNM may also beneficial in children. However, comparative data regarding preferred age of SNM for FC are lacking. Therefore, long-term results of SNM for FC were compared between children and adults. METHOD All patients treated with SNM for FC between 2004 and 2015 were evaluated. Outcomes of children (age 10-18 years) were compared with those for adults (≥ 18 years). The primary end-point was a defaecation frequency of three or more times per week, which is consistent with the ROME-III criteria. Secondary outcomes were quality of life (QoL; SF-36) and the Cleveland Clinic Constipation Score. RESULTS One hundred and eighty patients (45 children, 135 adults) were eligible for SNM. The mean age was 15.8 (children) and 41.4 years (adults). One hundred and twenty-six patients received permanent SNM (38 children, 88 adults). Mean follow-up was 47 months in both groups. Defaecation frequency increased in both groups after SNM compared with baseline. Defaecation frequency in adults was higher than in children. The increased defaecation frequency was maintained during the entire follow-up period in both groups. QoL of children was impaired compared with the Dutch population with regard to bodily pain, general health and vitality. Adults had worse QoL with regard to physical functioning, bodily pain, general health, vitality and social functioning compared with the Dutch population. QoL of children did not differ from adults. CONCLUSION Sacral neuromodulation (SNM) should be considered in children (< 18 years) with FC. However, the indication of SNM for FC remains debatable considering the limited improvements and high costs.

Cost-effectiveness of sacral neuromodulation for chronic refractory constipation in children and adolescents: a Markov model analysis. Colorectal Dis 2017; 19:1013-1023. [PMID: 28834055 DOI: 10.1111/codi.13869] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2016] [Accepted: 04/12/2017] [Indexed: 12/22/2022]
Abstract
AIM This study aimed to assess the cost-effectiveness of sacral neuromodulation (SNM) compared with conservative treatment in children and adolescents with constipation refractory to conservative management. METHOD A Markov probabilistic model was used, comparing costs and effectiveness of SNM and conservative treatment in children and adolescents aged 10-18 years with constipation refractory to conservative management. Input for the model regarding transition probabilities, utilities and healthcare costs was based on data from a cohort of patients treated in our centre. This cohort consisted of 30 female patients (mean age 16 years) with functional constipation refractory to conservative management. The mean duration of laxative use in this group was 5.9 years. All patients had a test SNM, followed by a permanent SNM in 27/30. Median follow-up was 22.1 months (range 12.2-36.8). The model was run to simulate a follow-up period of 3 years. RESULTS The mean cumulative costs for the SNM group and the conservative treatment group were €17 789 (SD €2492) and €7574 (SD €4332) per patient, respectively. The mean quality adjusted life years (QALYs) in the SNM group was 1.74 (SD 0.19), compared with 0.86 (SD 0.14) in the conservatively managed group. The mean incremental cost-effectiveness ratio was €12 328 per QALY (SD €4788). Sensitivity analysis showed that the outcomes were robust to a wide range of model assumptions. CONCLUSION Chronic constipation seriously affects the quality of life of children and adolescents. Preliminary evidence suggests that SNM can improve symptoms and quality of life at a reasonable cost.

Randomized clinical trial of percutaneous tibial nerve stimulation versus sham electrical stimulation in patients with faecal incontinence. Br J Surg 2017; 104:1167-1176. [PMID: 28703936 DOI: 10.1002/bjs.10590] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 01/18/2017] [Accepted: 04/06/2017] [Indexed: 12/17/2022]
Abstract
BACKGROUND The aim was to assess the effects of percutaneous tibial nerve stimulation (PTNS) in the treatment of faecal incontinence (FI) by means of an RCT. METHODS Patients aged over 18 years with FI were included in a multicentre, single-blinded RCT. The primary endpoint was reduction in the median or mean number of FI episodes per week. Secondary endpoints were changes in measures of FI severity, and disease-specific and generic quality of life. Outcomes were compared between PTNS and sham stimulation after 9 weeks of treatment. RESULTS A higher proportion of patients in the PTNS (13 of 29) than in the sham (6 of 30) group showed a reduction of at least 50 per cent in the median number of FI episodes/week (incidence rate ratio (IRR) 2·40, 95 per cent c.i. 1·10 to 5·24; P = 0·028), but not in the mean number of episodes/week (10 of 29 versus 8 of 30; IRR 1·42, 0·69 to 2·92; P = 0·347). The absolute median number of FI episodes per week decreased in the PTNS but not in the sham group (IRR 0·66, 0·44 to 0·98; P = 0·041), as did the mean number (IRR 0·65 (0·45 to 0·97); P = 0·034). Scores on the Cleveland Clinic Florida faecal incontinence scale decreased significantly in both groups, but more steeply in the PTNS group (mean difference -1·3, 95 per cent c.i. -2·6 to 0·0; P = 0·049). The aggregated mental component score of Short Form 36 improved in the PTNS but not in the sham group (mean difference 5·1, 0·5 to 9·6; P = 0·028). CONCLUSION PTNS may offer a small advantage in the clinical management of FI that is insufficiently responsive to conservative treatment. The key challenge will be to identify patients who may benefit most from this minimally invasive surgical procedure. Registration number: NCT00974909 (http://www.clinicaltrials.gov).

Alternatives to antibiotics for prevention of surgical infection. Br J Surg 2017; 104:e24-e33.

Abstract
BACKGROUND Surgical-site infection (SSI) is still the second most common healthcare-associated infection, after respiratory tract infection. SSIs are associated with higher morbidity and mortality rates, and result in enormous healthcare costs. In the past decade, several guidelines have been developed that aim to reduce the incidence of SSI. Unfortunately, there is no consensus amongst the guidelines, and some are already outdated. This review discusses the recent literature regarding alternatives to antibiotics for prevention of SSI. METHODS A literature search of PubMed/MEDLINE was performed to retrieve data on the prevention of SSI. The focus was on literature published in the past decade. RESULTS Prevention of SSI can be divided into preoperative, perioperative and postoperative measures. Preoperative measures consist of showering, surgical scrubbing and cleansing of the operation area with antiseptics. Perioperative factors can be subdivided as: environmental factors, such as surgical attire; patient-related factors, such as plasma glucose control; and surgical factors, such as the duration and invasiveness of surgery. Postoperative measures consist mainly of wound care. CONCLUSION There is a general lack of evidence on the preventive effectiveness of perioperative measures to reduce the incidence of SSI. Most measures are based on common practice and perceived effectiveness. The lack of clinical evidence, together with the stability of the high incidence of SSI (10 per cent for colorectal procedures) in recent decades, highlights the need for future research.

Abstract
BACKGROUND The aim of this study was to establish the oncological and functional results of organ preservation with a watch-and-wait approach (W&W) and selective transanal endoscopic microsurgery (TEM) in patients with a clinical complete or near-complete response (cCR) after neoadjuvant chemoradiation for rectal cancer. METHODS Between 2004 and 2014, organ preservation was offered if response assessment with digital rectal examination, endoscopy, and MRI showed (near) cCR. Watch-and-wait was offered for cCR, and two options were offered for near cCR: TEM or reassessment after three months. Follow-up included endoscopy and MRIs every three months during the first year, and every six months thereafter. Long-term outcome was assessed with Kaplan-Meier curves. Functional outcome was assessed with colostomy-free survival and Vaizey incontinence score (0 = perfect continence, 24 = totally incontinent). RESULTS One hundred patients were included, with median follow-up of 41.1 months. Sixty-one had cCR at initial response assessment. Thirty-nine had near cCR, of whom 24 developed cCR at the second assessment and 15 patients underwent TEM (9 ypT0, 1 ypT1, 5 ypT2). Fifteen patients developed a local regrowth (12 luminal, 3 nodal), all salvageable and within 25 months. Five patients developed metastases, and five patients died. Three-year overall survival was 96.6% (95% confidence interval [CI] = 89.9% to 98.9%), distant metastasis-free survival was 96.8% (95% CI = 90.4% to 99.0%), local regrowth-free survival was 84.6% (95% CI = 75.8% to 90.5%), and disease-free survival was 80.6% (95% CI = 70.9% to 87.4%). Colostomy-free survival was 94.8% (95% CI = 88.0% to 97.8%), with a good continence after watch-and-wait (Vaizey = 3.4, SD = 3.9) and moderate after TEM (Vaizey = 9.7, SD = 5.1). CONCLUSIONS Organ preservation appears oncologically safe for selected rectal cancer patients with a cCR or near cCR after neoadjuvant chemoradiation when applying strict selection criteria and frequent follow-up, including endoscopy and MRI. The low colostomy rate and the good long-term functional outcome warrant discussing this option with the patient as an alternative to major surgery.

Abstract
PURPOSE Functional constipation in children and adolescents is a common and invalidating condition. In a minority of patients, symptoms persist despite optimal conservative therapy. The aim of this study was to evaluate whether the short-term effects of sacral neuromodulation (SNM) in children and adolescents with constipation are sustained over prolonged period of time. METHODS Patients aged 10-20 years, with refractory constipation, fulfilling the Rome III criteria, were included in our study. If SNM test treatment showed >50 % improvement in defecation frequency, a permanent stimulator was implanted. Primary outcome measure was defecation frequency during 3 weeks. Secondary endpoints were abdominal pain and Wexner score. To assess sustainability of treatment effect, a survival analysis was performed. Cross-sectional quality of life was assessed using the EQ-5D VAS score. RESULTS Thirty girls, mean age 16 (range 10-20), were included. The mean defecation frequency increased from 5.9 (SD 6.5) in 21 days at baseline to 17.4 (SD 11.6) after 3 weeks of test treatment (p < 0.001). During test treatment, abdominal pain and Wexner score decreased from 3.6 to 1.5 and 18.6 to 8.5 (p < 0.001), respectively. Improvement of symptoms sustained during a median follow-up of 22.1 months (12.2-36.8) in 42.9 % of patients. On a scale from 0 to 100, quality of life was 7 points lower than the norm score (mean 70 vs. 77). CONCLUSION SNM is a therapeutic option for children with chronic constipation not responding to intensive oral and/or laxative therapy, providing benefits that appear to be sustained over prolonged period of time.

Abstract
Background Currently there is no guideline for the treatment of patients with Crohn’s disease and high perianal fistulas. Most patients receive anti-TNF medication, but no long-term results of this expensive medication have been described, nor has its efficiency been compared to surgical strategies. With this study, we hope to provide treatment consensus for daily clinical practice with reduction in costs. Methods/Design This is a multicentre, randomized controlled trial. Patients with Crohn’s disease who are over 18 years of age, with newly diagnosed or recurrent active high perianal fistulas, with one internal opening and no anti-TNF usage in the past three months will be considered. Patients with proctitis, recto-vaginal fistulas or anal stenosis will be excluded. Prior to randomisation, an MRI and ileocolonoscopy are required. All treatment will start with seton placement and a course of antibiotics. Patients will then be randomised to: (1) chronic seton drainage (with oral 6-mercaptopurine (6MP)) for one year, (2) anti-TNF medication (with 6MP) for one year (seton removal after six weeks) or (3) advancement plasty after eight weeks of seton drainage (under four months anti-TNF and 6MP for one year). The primary outcome parameter is the number of patients needing fistula-related re-intervention(s). Secondary outcomes are the number of patients with closed fistulas (based on an evaluated MRI score) after 18 months, disease activity, quality of life and costs. Discussion The PISA trial is a multicentre, randomised controlled trial of patients with Crohn’s disease and high perianal fistulas. With the comparison of three generally accepted treatment strategies, we will be able to comment on the efficiency of the various treatment strategies, with respect to several long-term outcome parameters.

Abstract
Background The response to chemoradiotherapy (CRT) for rectal cancer can be assessed by clinical examination, consisting of digital rectal examination (DRE) and endoscopy, and by MRI. A high accuracy is required to select complete response (CR) for organ-preserving treatment. The aim of this study was to evaluate the value of clinical examination (endoscopy with or without biopsy and DRE), T2W-MRI, and diffusion-weighted MRI (DWI) for the detection of CR after CRT. Methods This prospective cohort study in a university hospital recruited 50 patients who underwent clinical assessment (DRE, endoscopy with or without biopsy), T2W-MRI, and DWI at 6–8 weeks after CRT. Confidence levels were used to score the likelihood of CR. The reference standard was histopathology or recurrence-free interval of >12 months in cases of wait-and-see approaches. Diagnostic performance was calculated by area under the receiver operator characteristics curve, with corresponding sensitivities and specificities. Strategies were assessed and compared by use of likelihood ratios. Results Seventeen (34 %) of 50 patients had a CR. Areas under the curve were 0.88 (0.78–1.00) for clinical assessment and 0.79 (0.66–0.92) for T2W-MRI and DWI. Combining the modalities led to a posttest probability for predicting a CR of 98 %. Conversely, when all modalities indicated residual tumor, 15 % of patients still experienced CR. Conclusions Clinical assessment after CRT is the single most accurate modality for identification of CR after CRT. Addition of MRI with DWI further improves the diagnostic performance, and the combination can be recommended as the optimal strategy for a safe and accurate selection of CR after CRT.

Abstract
PURPOSE Perianal fistulas, and specifically high perianal fistulas, remain a surgical treatment challenge. Many techniques have, and still are, being developed to improve outcome after surgery. A systematic review and meta-analysis was performed for surgical treatments for high cryptoglandular perianal fistulas. METHODS Medline (Pubmed, Ovid), Embase and The Cochrane Library databases were searched for relevant randomized controlled trials on surgical treatments for high cryptoglandular perianal fistulas. Two independent reviewers selected articles for inclusion based on title, abstract and outcomes described. The main outcome measurement was the recurrence/healing rate. Secondary outcomes were continence status, quality of life and complications. RESULTS The number of randomized trials available was low. Fourteen studies could be included in the review. A meta-analysis could only be performed for the mucosa advancement flap versus the fistula plug, and did not show a result in favour of either technique in recurrence or complication rate. The mucosa advancement flap was the most investigated technique, but did not show an advantage over any other technique. Other techniques identified in randomized studies were seton treatment, medicated seton treatment, fibrin glue, autologous stem cells, island flap anoplasty, rectal wall advancement flap, ligation of intersphincteric fistula tract, sphincter reconstruction, sphincter-preserving seton and techniques combined with antibiotics. None of these techniques seem superior to each other. CONCLUSIONS The best surgical treatment for high cryptoglandular perianal fistulas could not be identified. More randomized controlled trials are needed to find the best treatment. The mucosa advancement flap is the most investigated technique available.

Abstract
PURPOSE Fistulotomy is considered to be the golden standard for the treatment of low perianal fistula but might have more influence on continence status than believed. This study was performed to evaluate the healing rate after a fistulotomy and to show results for continence status. METHODS A retrospective database study was performed in one university medical center and its six affiliated hospitals. All patients treated with a fistulotomy for a low perianal fistula were identified. Healing and recurrence of the fistula were identified. Questionnaires on continence status and quality of life were mailed to all patients. RESULTS In total, 537 patients were identified. The primary etiology of the fistulas was cryptoglandular (66.5%). Recurrence was seen in 88 patients (16.4%) resulting in a primary healing rate of 83.6%. After secondary treatment for the recurrence, another 40 patients healed. This resulted in a secondary healing rate of 90.3%. The Kaplan-Meier analysis showed that at 5 years, the healing rate was 0.81 (95% confidence interval (95% CI) 0.71-0.85). The mean Vaizey score was 4.67 (SD 4.80). Major incontinence, defined as a Vaizey score of >6, was seen in 95 (28.0%) patients. Only 26.3% of the patients had a perfect continence status (Vaizey score 0). Quality of life was not different from the general population. CONCLUSIONS Fistulotomy seems to be associated with a healing rate of 0.81 (95% CI 0.71-0.85) after 5 years. However, major incontinence is still reported by 26.8% of patients and only 26.3% of patients had a perfect continence status.

Abstract
AIM To give an overview of the microbiology of blood and wound samples from surgical site infections (SSIs) after gastrointestinal surgery, as well as the antimicrobial susceptibility of the microorganisms involved, and to discuss the appropriateness of the prophylactic antibiotics administered. MATERIALS & METHODS During a 3.5-year study period, wound swabs and blood samples of patients with an SSI were taken in the first 48 h after surgery until 30 days thereafter. RESULTS Most pathogens were isolated from wound swabs. Escherichia coli (25%) and Pseudomonas aeruginosa (10%) were the most frequently found microorganisms. Both microorganisms showed a slight tendency towards a decrease in susceptibility for the tested antibiotics, although after correction, this was not significant. CONCLUSION The comparison between wound swabs taken in the first 48 h after a surgical procedure and swabs in the 30 days thereafter provides important information concerning the microbiology of SSIs and the development of antibiotic resistance of the causative agents over time.

Abstract
BACKGROUND Treatment of rectovaginal fistulas is difficult, and many surgical interventions have been developed. The best surgical intervention for the closure of these fistulas is still unclear. OBJECTIVE A systematic review was performed reporting the outcomes of different surgical techniques for rectovaginal fistulas. DATA SOURCES Medline (PubMed, Ovid), Embase (Ovid), and The Cochrane Library databases were searched for eligible articles as well as the references of these articles. STUDY SELECTION Two independent reviewers analyzed the search results for eligible articles based on title, abstract, and described results. INTERVENTION(S) Any surgical intervention for the closure of rectovaginal fistulas was included. MAIN OUTCOME MEASURES The main outcome was closure rate. Secondary outcomes were quality of life, morbidity, and the effect on sexual functioning. RESULTS Many articles with different operative techniques were identified and classified in the following categories: advancement flaps (endorectal and endovaginal), transperineal closure, Martius procedure, gracilis muscle transposition, rectal resections, transabdominal closure, mesh repair, plugs, endoscopic repairs, closure with biomaterials, and miscellaneous techniques. Results vary widely with closure rates between 0% and >80%. None of the studies were randomized. Because of the poor quality of the identified studies, the comparison of results and performance of a meta-analysis were not possible.Data regarding the secondary outcomes were mostly unavailable. LIMITATIONS The major limitation of this review was the limited availability of high-quality prospective studies, making it impossible to perform a meta-analysis. CONCLUSIONS No conclusion about the best surgical intervention for rectovaginal fistulas could be formulated. More large studies of high quality are needed to find the best treatment for rectovaginal fistulas. A design for these high-quality studies was formulated.

Modern multidisciplinary treatment of rectal cancer based on staging with magnetic resonance imaging leads to excellent local control, but distant control remains a challenge. Eur J Cancer 2013; 49:2311-20. [PMID: 23571146 DOI: 10.1016/j.ejca.2013.03.006] [Citation(s) in RCA: 78] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2012] [Revised: 02/01/2013] [Accepted: 03/03/2013] [Indexed: 01/26/2023]
Abstract
AIM The purpose of this multicenter cohort study was to evaluate whether a differentiated treatment of primary rectal cancer based on magnetic resonance imaging (MRI) can reduce the number of incomplete resections and local recurrences and improve recurrence-free and overall survival. METHODS From February 2003 until January 2008, 296 patients with rectal cancer underwent preoperative MRI using a lymph node specific contrast agent to predict circumferential resection margin (CRM), T- and N-stage. Based on expert reading of the MRI, patients were stratified in: (a) low risk for local recurrence (CRM>2mm and N0 status), (b) intermediate risk and (c) high risk (close/involved CRM, N2 status or distal tumours). Mainly based on this MRI risk assessment patients were treated with (a) surgery only (TME or local excision), (b) preoperative 5 × 5 Gy+TME and (c) a long course of chemoradiation therapy followed by surgery after a 6-8 week interval. RESULTS Overall 228 patients underwent treatment with curative intent: 49 with surgery only, 86 with 5 × 5 Gy and surgery and 93 with chemoradiation and surgery. The number of complete resections (margin>1mm) was 218 (95.6%). At a median follow-up of 41 months the three-year local recurrence rate, disease-free survival rate and overall survival rate is 2.2%, 80% and 84.5%, respectively. CONCLUSION With a differentiated multimodality treatment based on dedicated preoperative MR imaging, local recurrence is no longer the main problem in rectal cancer treatment. The new challenges are early diagnosis and treatment, reducing morbidity of treatment and preferably prevention of metastatic disease.

Abstract
PURPOSE This study was designed to investigate how the quality of life of patients with rectal cancer changes with time after laparoscopic total mesorectal excision. METHODS Patients completed the Medical Outcomes Study Short Form 36 and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and a colorectal-specific European Organisation for Research and Treatment of Cancer quality of life questionnaire before laparoscopic total mesorectal excision, on discharge from the hospital and at 3, 6, and 12 months postoperatively. Patients were treated by laparoscopic low anterior resection or laparoscopic abdominoperineal resection. RESULTS Fifty-one patients (mean age, 64 years; 29 males (57 percent)) participated in this study, of whom 38 (75 percent) underwent laparoscopic low anterior resection and 13 (25 percent) laparoscopic abdominoperineal resection. Compared with preoperative scores on the Medical Outcomes Study Short Form 36, patients reported a deterioration in physical functioning (74 vs. 80; P = 0.009), and improved mental functioning (76 vs. 70; P = 0.007) at three months. Improvement in emotional well-being was reported both on the Medical Outcomes Study Short Form 36 (78 vs. 53; P = 0.006) and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (84 vs. 69; P < 0.001). At one year, improvements in global quality of life (82 vs. 68; P = 0.001) and symptoms, such as fatigue (18 vs. 32; P < 0.001), pain (5 vs. 12; P = 0.009), and appetite loss (3 vs. 13; P = 0.01), were reported. Sexual functioning was worse from three months onward until one year after surgery (47 vs. 66; P = 0.004). Patients who underwent low anterior resection experienced less sexual dysfunction than patients after abdominoperineal resection (21 vs. 56; P = 0.004). CONCLUSIONS One year after laparoscopic total mesorectal excision for rectal cancer, patients reported improvement in some important quality of life outcomes, including global quality of life, despite a decrease in sexual functioning.

Abstract
With the introduction of total mesorectal excision (TME) for treatment of rectal cancer, the prognosis of patients with rectal cancer is improved. With this better prognosis, there is a growing awareness about the quality of life of patients after rectal carcinoma. Laparoscopic total mesorectal excision (LTME) for rectal cancer offers several advantages in comparison with open total mesorectal excision (OTME), including greater patient comfort and an earlier return to daily activities while preserving the oncologic radicality of the procedure. Moreover, laparoscopy allows good exposure of the pelvic cavity because of magnification and good illumination. The laparoscope seems to facilitate pelvic dissection including identification and preservation of critical structures such as the autonomic nervous system. The technique for laparoscopic autonomic nerve preserving total mesorectal excision is reported. A three- or four-port technique is used. Vascular ligation, sharp mesorectal dissection and identification and preservation of the autonomic pelvic nerves are described.
