Quality of life after laparoscopic sigmoid resection for uncomplicated diverticular disease

Quality of life with diverticular disease: translation and validation of the German version of the diverticulitis quality of life questionnaire (DV-QOL)

BACKGROUND

The DV-QoL is a 17-item questionnaire measuring health-related quality of life in patients affected by symptomatic diverticular disease, covering four domains: physical symptoms, concerns, feelings, and behavioral changes. Given the lack of a diverticulitis-specific questionnaire to be used for German-speaking patients, we prospectively validated the German version of the DV-QoL.

METHODS

German-speaking patients with CT-confirmed history of recurrent diverticular disease admitted to a Swiss surgical department completed the German version of the DV-QoL, along with short form-36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI). Reliability was examined using exploratory and confirmatory factor analysis, a Martin-Loef test, and Cronbach's alpha. For convergent validity testing, correlations were calculated with the GIQLI and SF-36. Discriminant validity tests included age and gender.

RESULTS

We included 121 patients, of whom 77 were admissions for elective surgery and 44 presented with acute diverticulitis treated conservatively. The DV-QoL's total score showed good correlations with the GIQLI (r = - 0.77) and its subscales (r = - 0.76 to - 0.45), as well as with the SF-36's subscales (r = - 0.30 to - 0.57). No relationships were found with age or gender (p < 0.05). The Cronbach's alpha coefficient was 0.89 over all items and 0.69, 0.90, 0.78, and 0.77 for the four separated domains (physical symptoms, cognitions/concerns, feelings, and behavioral changes, respectively). A nonsignificant Martin-Loef test indicated unidimensionality (p = 1), further supported by the exploratory factor analysis, which showed an item information sharing of 65%.

CONCLUSION

The German DV-QoL questionnaire can be used as a valid and reliable disease-specific measure for quality of life in patients with recurrent diverticular disease.

Preservation of left colic artery in laparoscopic colorectal operation: The benefit challenge

BACKGROUND

During laparoscopic resection for colorectal cancer, there is controversy regarding whether the left colic artery (LCA) should be preserved at its origin.

AIM

To investigate the prognostic significance of preservation of the LCA in colorectal cancer surgery.

METHODS

Patients were divided into two groups. The high ligation (H-L) technique (refers to ligation performed 1 cm from the beginning of the inferior mesenteric artery) group consisted of 46 patients, and the low ligation (L-L) technique (refers to ligation performed below the initiation of the LCA) group consisted of 148 patients. Operative time, blood loss, lymph nodes with tumor invasion, postoperative complications and recovery time, recurrence rate, and 5-year survival rate were compared between the two groups.

RESULTS

The average number of lymph nodes detected in postoperative pathological specimens was 17.4/person in the H-L group and 15.9/person in the L-L group. There were 20 patients (43%) with positive lymph nodes (lymph node metastasis) in the H-L group and 60 patients (41%) in the L-L group. No statistical differences were found between the groups. Complications occurred in 12 cases (26%) in the H-L group and in 26 cases (18%) in the L-L group. The incidences of postoperative anastomotic complications and functional urinary complications were significantly lower in the L-L group. The 5-year survival rates in H-L and L-L groups were 81.7% and 81.6%, respectively, and relapse-free survival rates were 74.3% and 77.1%, respectively. The two groups were similar statistically.

CONCLUSION

Complete mesenteric resection combined with lymph node dissection around the inferior mesenteric artery root while preserving the LCA is a beneficial surgical approach during laparoscopic resection for colorectal cancer.

Elective surgical versus conservative management of complicated diverticulitis: A systematic review and meta-analysis

OBJECTIVES

There is no consensus on the optimal treatment for patients with complicated diverticulitis. In this systematic review and meta-analysis we aimed to determine the indications for elective surgery in complicated diverticulitis by comparing conservative treatment with elective surgery.

METHODS

A meta-analysis of recurrence, morbidity and stoma rates was performed using a random effects model. Patient-reported quality of life (QoL) and cost-effectiveness outcomes were synthesized qualitatively.

RESULTS

Eleven randomized controlled trials and non-randomized studies with a total of 7415 patients were included. In statistical terms, the recurrence of diverticulitis was significantly higher in the conservatively treated group than in the elective surgery group (odds ratio [OR] 0.24, 95% confidence interval [CI] 0.12-0.51). The stoma rate (OR 2.34, 95% CI 1.88-2.92) and the morbidity rate (OR 4.29, 95% CI 2.24-8.23) were significantly higher in the elective surgery group than in the conservatively treated group. There was some evidence for a significant increase in QoL and long-term cost-effectiveness in the elective surgery group than in the conservatively treated group.

CONCLUSIONS

Indications for elective surgery should not include the prevention of emergency colostomy or complications. Elective surgical resection may be considered in patients with complicated diverticulitis with the goal of improving their QoL and long-term cost-effectiveness.

Emerging evidence and recent controversies in diverticulitis: a 5-year review

Diverticulitis is a common gastrointestinal disease that still garners significant attention and study because of its heterogeneity in presentation and outcome. We provide a review of the newest and most controversial topics in diverticulitis. Recent discoveries on the influence of diet and other environmental risk factors are discussed, showing how the epidemiology of the disease process is shifting away from what was previously felt to be a disorder primarily limited to older western populations. Interestingly, as has long been suspected, genetic mutations and variations associated with the development of diverticulitis are being discovered and are summarized here. The data for non-operative and outpatient management of diverticulitis are reviewed, as are pharmacologic agents studied for use in the secondary prevention of diverticulitis. Lastly, we present controversies in the surgical treatment of diverticulitis. This review will provide a synopsis of the last 5 years of literature relating to diverticulitis.

Health-related quality of life and functional disorders after diverticular surgery

Diverticulosis and diverticulitis are leading indications for colorectal surgery in Western countries. Abdominal pain, functional disorders, and low health-related quality of life (HRQoL) can limit the outcome of abdominal surgery even in the absence of complications. Therefore, we aimed to review current evidence on postoperative long-term outcomes including HRQoL, functional disorders, abdominal pain, and patients' satisfaction after diverticular surgery for diverticulosis/diverticulitis. We performed a PubMed database search (inception: 17 December 2020). Identified publications were screened and outcome parameters extracted. In summary, HRQoL increased after diverticular surgery in 9 out of 10 longitudinal cohort studies. Similarly, patients' satisfaction with treatment and their choice to undergo surgery was commonly reported as high or very good, as reported in eight studies. In a randomized control trial and retrospective cohort, elective diverticular surgery was superior to conservative treatment regarding HRQoL. In cross-sectional analyses, chronic abdominal pain and functional disorders including defaecation disorders or diarrhoea/obstipation were found in a relevant fraction of patients. Incontinence ranged from 5% to 25% with insufficient data for comparison before and after surgery. However, functional disorders did not result in decreased HRQoL in most studies, and no increase in functional disorders was observed after elective diverticular surgery in longitudinal analyses. We conclude that HRQoL among operated patients with diverticular disease improved in most studies after surgery. Functional disorders and postoperative abdominal pain can be present after elective diverticular surgery; however, no increase in functional disorders was observed in longitudinal studies. Functional disorders after diverticular surgery need to be carefully discussed with the patient before surgery and a careful clinical assessment before surgery including incontinence scoring should be considered.

Changing Paradigms in the Management of Acute Uncomplicated Diverticulitis

Left-sided colonic diverticulitis is a common condition with significant morbidity and health care costs in Western countries. Acute uncomplicated diverticulitis which is characterized by the absence of organ dysfunction, abscesses, fistula, or perforations accounts for around 80% of the cases. In the last decades, several traditional paradigms in the management of acute uncomplicated diverticulitis have been replaced by evidence-based routines. This review provides a comprehensive evidence-based and clinical-oriented overview of up-to-date diagnostics with computer tomography, non-antibiotic treatment, outpatient treatment, and surgical strategies as well as follow-up of patients with acute uncomplicated diverticulitis.

Predictive model estimating the decrease of postoperative gastrointestinal quality of life index (GIQLI) in patients after elective laparoscopic sigmoid resection for diverticular disease

Background

Growing consideration in quality of life (QoL) has changed the therapeutic strategy in patients suffering from diverticular disease. Patients’ well-being plays a crucial role in the decision-making process. However, there is a paucity of studies investigating patients’ or surgery-related factors influencing the postoperative gastrointestinal function. The aim of this study was to investigate in a predictive model patients or surgical variables that allow better estimation of the postoperative gastrointestinal QoL.

Methods

This observational study retrospectively analyzed patients undergoing elective laparoscopic sigmoidectomy for diverticulitis between 2004 and 2017. The one-time postoperative QoL was assessed with the gastrointestinal quality of life index (GIQLI) in 2019. A linear regression model with stepwise selection has been applied to all patients and surgery-related variables.

Results

Two hundred seventy-two patients with a mean age of 62.30 ± 9.74 years showed a mean GIQLI of 116.39±18.25 at a mean follow-up time of 90.4±33.65 months. Women (n=168) reported a lower GIQLI compared to male (n=104; 112.85±18.79 vs 122.11±15.81, p<0.001). Patients with pre-operative cardiovascular disease (n=17) had a worse GIQLI (106.65 ±22.58 vs 117.08±17.66, p=0.010). Finally, patients operated less than 5 years ago (n=63) showed a worse GIQLI compared to patients operated more than 5 years ago (n=209; 111.98±19.65 vs 117.71±17.63, p=0.014).

Conclusions

Female gender and the presence of pre-operative cardiovascular disease are predictive for a decreased postoperative gastrointestinal QoL. Furthermore, patients’ estimation of gastrointestinal functioning seems to improve up to 5 years after surgery.

Long-term urogenital assessment after elective laparoscopic sigmoid resection for diverticulitis: a comparison between central and peripheral vascular resection

AIM

Increasing attention has been given to postoperative gastrointestinal functional outcome and quality of life after sigmoid resection for diverticulitis. Conversely, very little has been described about postoperative urogenital functional outcome and even less about its potential relationship to the type of vascular approach. The aim of this study was to evaluate whether central ligation of the inferior mesenteric artery (IMA) compared with peripheral dissection could impair urinary and sexual function in the long term.

METHOD

Patients undergoing elective laparoscopic sigmoid resection for diverticulitis from 2004 to 2017 were retrospectively analysed. They were asked to complete the American Urological Association Symptom Index (AUASI) questionnaire. Men received the five-item version of the International Index of Erectile Function (IIEF-5) questionnaire. Patients were then divided according to the type of vascular resection.

RESULTS

A response rate of the 36.4% to the AUASI and 43.8% to the IIEF-5 questionnaires was achieved. Three hundred and twenty four patients with a mean age of 62 ± 9.85 years were analysed for their urinary function (IMA preserved n = 217; IMA resected n = 107) in a median follow-up of 87 months. Furthermore, 115 men with a mean age of 60 ± 8.97 years were investigated for their sexual function (IMA preserved n = 80; IMA resected n = 35) in a median follow-up of 89 months. No difference (AUASI: 8 ± 6.32 IMA preserved vs. 7 ± 6.26 IMA resected, P = 0.204; IIEF-5: 15 ± 7.67 IMA preserved vs. 15 ± 8.61 IMA resected, P = 0.674) was found regarding the type of vascular approach during sigmoid resection.

CONCLUSIONS

No association was found between the type of vascular approach and the long-term urogenital functional outcome in patients undergoing sigmoid resection for diverticulitis.

The Indications for and Timing of Surgery for Diverticular Disease

BACKGROUND

Diverticular disease is one of the more common abdominal disorders. In 2016, approximately 130 000 patients received inpatient treatment for diverticular disease in Germany. The disease has a number of subtypes, each of which has an appropriate treatment. In this article, we present the current surgical indications and optimal timing of surgery for diverticular disease.

METHODS

This review is based on publications that were retrieved by an extensive, selective search in Medline and the Cochrane Library (1998-2018) for studies and guidelines with information on the indications for surgery in diverticular disease.

RESULTS

Studies of evidence grades 2 to 4 were available. Patients receiving a diagnosis of freely perforated diverticulitis and peritonitis (Classification of Diverticular Disease [CDD] type 2c) should be operated on at once. Covered perforated diverticulitis with a macroabscess (>1 cm, CDD type 2b) may be an indication for elective surgery after successful conservative treatment. New evidence from a randomized, controlled trial suggests that elective surgery should also be considered for patients with chronic recurrent diverticulitis (CDD type 3b). The decisive factor in such cases is the impairment of the quality of life for the individual patient. Elective surgery is indicated in chronic recurrent diverticulitis with complications (fistulae, stenoses). Asymptomatic diverticulosis (CDD type 0) and uncomplicated diverticulitis (CDD type 1) are not surgical indications. Likewise, in diverticular hemorrhage (CDD type 4), surgery is only indicated in exceptional cases, when conservative treatment fails.

CONCLUSION

The surgical indication and the proper timing of surgery depend on the type of disease that is present. Future studies should more thoroughly investigate the effect of surgery on the quality of life in patients with the various types of diverticular disease.

Long-Term Functional Results of a Modified Caudal-to-Cranial Approach in Laparoscopic Segmental Left Colectomy for Diverticular Disease

A modified caudal-to-cranial approach to perform laparoscopic left colectomy for benign diseases has been recently designed to facilitate the low-tie mesenteric dissection. A chart review has been performed including all consecutive patients with uncomplicated diverticulitis who have been treated by segmental left colectomy with a caudal-to-cranial approach. A total of 34 patients were included in the study. 21 patients were male, mean age was 54.1 ± 11.3, and mean BMI was 26 ± 5.5. Patients with ASA Score I were 7, with ASA II were 9, and with ASA Score III were 5. Incontinence Score (IS) resulted in an average of 5 ± 2, 2 grade of incontinence and the CS score showed an average of 10 ± 3, 2 grade of constipation. Health status, evaluated by Short Form-36 questionnaire, was demonstrated in these patients' great physical function, role, general health, and social function. The anorectal manometry performed 6 months after surgery showed a normal value in terms of the anal resting pressure (47 ± 13 mmHg) and an increased volume to stimulate desire to defecate (197 ± 25 ml). The length of the anal sphincter was normal compared to the reference value (37 ± 5.4 mm). Although further studies are required to obtain definitive conclusions, our results are encouraging to propose low-tie segmental colectomy as the standard procedure for the treatment of uncomplicated diverticulitis, and our modified surgical approach could be considered useful to facilitate the surgical approach.

European Society of Coloproctology: guidelines for the management of diverticular disease of the colon

AIM

The goal of this European Society of Coloproctology (ESCP) guideline project is to give an overview of the existing evidence on the management of diverticular disease, primarily as a guidance to surgeons.

METHODS

The guideline was developed during several working phases including three voting rounds and one consensus meeting. The two project leads (JKS and EA) appointed by the ESCP guideline committee together with one member of the guideline committee (WB) agreed on the methodology, decided on six themes for working groups (WGs) and drafted a list of research questions. Senior WG members, mostly colorectal surgeons within the ESCP, were invited based on publication records and geographical aspects. Other specialties were included in the WGs where relevant. In addition, one trainee or PhD fellow was invited in each WG. All six WGs revised the research questions if necessary, did a literature search, created evidence tables where feasible, and drafted supporting text to each research question and statement. The text and statement proposals from each WG were arranged as one document by the first and last authors before online voting by all authors in two rounds. For the second voting ESCP national representatives were also invited. More than 90% agreement was considered a consensus. The final phrasing of the statements with < 90% agreement was discussed in a consensus meeting at the ESCP annual meeting in Vienna in September 2019. Thereafter, the first and the last author drafted the final text of the guideline and circulated it for final approval and for a third and final online voting of rephrased statements.

RESULTS

This guideline contains 38 evidence based consensus statements on the management of diverticular disease.

CONCLUSION

This international, multidisciplinary guideline provides an up to date summary of the current knowledge of the management of diverticular disease as a guidance for clinicians and patients.

Functional and Short-term Outcomes in Elective Laparoscopic Colectomy for Symptomatic Diverticular Disease With Either Low Ligation or Inferior Mesenteric Artery Preservation: A Randomized Trial

BACKGROUND

The current treatment of symptomatic diverticular disease is left colectomy/sigmoidectomy with low ligation of the inferior mesenteric artery versus the inferior mesenteric artery preservation. Up to now, there is no strong evidence in favor of one of the 2 strategies. The aim of this study is to compare the bowel-specific quality of life and functional outcomes between these 2.

METHODS

Between June 2015 and February 2019, patients were randomly assigned to inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for diverticular disease. Gastrointestinal, genitourinary functions and surgical outcomes were compared postoperatively between groups.

RESULTS

One-hundred sixty-eight patients were randomized providing 2 homogenous groups. Gastrointestinal and genitourinary functions were not significantly different between groups after 1 and 6 months postoperative. In both groups, the function was restored to the preoperative level 6 months after surgery. There was no statistically significant difference in terms of conversion rate, blood loss, length of surgery, between groups. There was no difference in the overall complication rate and the anastomotic leak rate among groups.

CONCLUSIONS

Inferior mesenteric artery low ligation or inferior mesenteric artery preservation during elective laparoscopic sigmoidectomy for a diverticular disease can be considered equivalent in affecting the postoperative bowel-related quality of life, genitourinary function, and surgical outcomes.

[Functional Results after Laparoscopic versus Robot-assisted Sigmoid Resection in Diverticulitis]

BACKGROUND

Sigmoid resection in diverticulitis is one of the most frequently performed colonic operations. A minimally invasive approach by laparoscopy is the surgical gold standard. For a few years now, sigmoid resections have also been performed robotically (da Vinci^® System). It is unclear whether there are relevant differences between the two procedures in terms of functional outcome.

METHODS

A postoperative follow-up was performed on all patients who underwent laparoscopic or robotic sigmoid resection for diverticulitis between November 2013 and November 2018, with a minimum interval of 6 months between surgery. Continence disorders, the development of symptoms compared to preoperative, changes in bowel movement (constipation, diarrhoea), impairment in daily life and pain were recorded. Differences between the groups were checked for statistical significance using the chi-square test.

RESULTS

During the study period, a total of 106 minimally invasive sigmoid resections for diverticulitis were performed (laparoscopic: n = 46, robot-assisted: n = 60). Of these, 74 patients (70%; laparoscopic: n = 28, robot-assisted: n = 46) answered the questionnaire and were included in the evaluation. Continence disorders were reported in a total of 22% of cases. There was no statistically significant difference between the groups in any of the variables surveyed.

CONCLUSION

With regard to functional results after minimally invasive sigmoid resection for diverticulitis, laparoscopic and robot-assisted sigmoid resection can be considered equivalent procedures.

Quality of life in uncomplicated recurrent diverticulitis: surgical vs. conservative treatment

Elective sigmoid colectomy for recurrent uncomplicated diverticulitis remains controversial and is decided on an individual basis. Eighty patients treated conservatively (44 patients) or by elective surgery (36 patients) for recurrent uncomplicated diverticulitis were contacted and assessed for quality of life. The mean difference in quality of life scores was greater after surgery (overall + 2.14%, laparoscopic resection +4.95%, p = 0.36 and p = 0.11, respectively) as compared to conservative management. Female patients undergoing laparoscopic resection had statistically significantly higher quality of life scores than women treated conservatively (+8.98%; p = 0.049). Twenty-eight of 29 responding patients stated that they were highly satisfied and would have the operation done again. Elective sigmoidectomy is a valid treatment option for recurrent uncomplicated diverticulitis in terms of quality of life. Quality of life improved most if surgery was performed laparoscopically, especially in women.

Elective Laparoscopic Sigmoid Colectomy for Diverticulitis-an Updated Look at Recurrence After Surgery

BACKGROUND

Surgical management of diverticulitis is evolving and the decision to offer elective sigmoidectomy for diverticulitis has become more individualized. However, preoperative variables that may predict recurrent diverticulitis after resection and guide surgical decision-making were not well studied.

METHODS

This was a retrospective chart review with a prospective questionnaire follow-up of patients. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included and their medical records reviewed. They were then contacted with a questionnaire to inquire about recurrence of diverticulitis since resection. The primary outcome was rate of recurrent diverticulitis after elective sigmoidectomy. The secondary outcome was risk factors for recurrence after sigmoidectomy.

RESULTS

Of 662 patients who underwent elective sigmoidectomy for diverticulitis, 361 had long-term follow-up data available. Mean follow-up was 86 months. Indication for surgery was uncomplicated recurrent diverticulitis in 50%. Recurrent diverticulitis developed in 15 (4.2%) patients. Mean time to recurrence was 55 (range, 6-109) months. All recurrences were confirmed by CT scan. Univariate analysis showed that preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was significantly more prevalent in patients who experienced recurrent diverticulitis after sigmoidectomy (p = 0.049 and p = 0.02); however, these variables did not predict recurrence after resection.

CONCLUSIONS

Overall rate of recurrent diverticulitis after elective sigmoidectomy was 4.2%. Preoperative diagnosis of irritable bowel syndrome and uncomplicated recurrent diverticulitis was associated with but not significant predictor of recurrence after elective resection.
