Diao YH, Chen J, Liu Y, Peng D, Yang D. Does aortic calcification really affect anastomotic leakage after rectal cancer surgery? Medicine (Baltimore) 2024; 103:e38860. [PMID: 38996164 PMCID: PMC11245182 DOI: 10.1097/md.0000000000038860] [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: 01/17/2024] [Accepted: 06/17/2024] [Indexed: 07/14/2024] Open
Abstract
The purpose of the current study was to analyze whether aortic calcification had impact on the anastomotic leakage (AL) after rectal cancer (RC) surgery. We collected patients' information from January 2011 to January 2020 in a single teaching hospital. Preoperative computed tomography images were obtained. Abdominal aortic calcification (AAC), superior mesenteric aortic calcification, and inferior mesenteric aortic calcification were recorded. The difference of AL and grade C AL was calculated. A total of 2412 RC patients were included in this study. Ninety-seven (4.0%) RC patients experienced AL and 47 (1.9%) RC patients experienced grade C AL. The amount of AAC, superior mesenteric aortic calcification, and inferior mesenteric aortic calcification was 1546 (64.1%), 128 (5.3%), and 31 (1.3%). The AL group had higher portion of AAC (P = .019) than the no AL group, and the grade C AL group had higher portion of AAC (P = .016) than the no grade C AL group. In univariate logistic regression analysis, AAC was a significant potential factor for AL (P = .021, OR = 1.739, 95% CI = 1.088-2.779) and grade C AL (P = .019, OR = 2.339, 95% CI = 1.115-4.986). However, in multivariate logistic regression, AAC was not an independent predictive factor for AL (P = .157, OR = 1.443, 95% CI = 0.871-2.358) or grade C AL (P = .064, OR = 2.055, 95% CI = 0.960-4.399). AAC was associated with higher amount of AL and grade C AL, however, AAC was not an independent predictive factor for AL or grade C AL.

Abstract
INTRODUCTION Surgical intervention for rectal cancer is widely recognized for its potential to significantly impact quality of life, chiefly due to the high probability of permanent colostomy and the associated postoperative complications. OBJECTIVE This study aimed to evaluate the short-term outcomes and morbidity associated with total mesorectal excision for middle and lower rectal cancer within an Iraqi cohort, in a prospective setting. METHODS This study prospectively collected and analyzed data from 89 patients who underwent a standardized radical rectal resection, with a follow-up period extending to one month post-surgery. RESULTS The mean age of patients was 54.4 ± 12.9 years, with a gender distribution of 46 males and 43 females. A total of 33 patients presented with preoperative comorbidities, which heightened the risk of adverse short-term outcomes by a factor of 7.51. The most prevalent comorbidities were hypertension and diabetes mellitus, affecting 22 and 20 patients, respectively. Patients aged 60 years and above were at a 3.97 times greater risk of developing complications. The overall complication rate was 21.35%, with wound infections (9.0%) and cardiovascular events (3.4%) being the most common. Mortality during the follow-up was 1.1%. CONCLUSION The findings indicate that increased age and the presence of comorbidities are significant risk factors for morbidity and mortality post-surgery. Neoadjuvant chemoradiotherapy or radiotherapy was shown to reduce morbidity and mortality rates while improving survival. The morbidity and mortality rates observed in this study concur with existing literature.

Abstract
AIM Rectal cancers requiring beyond total mesorectal excision (bTME) are traditionally operated using an open approach, but the use of minimally invasive robot-assisted procedures is increasing. Introduction of minimal invasive surgery for complex cancer cases could be associated with compromised surgical margins or increased complication rates. Therefore, reporting results both clinical and oncological in large series is important. Since bTME procedure reports are heterogeneous, comparing results is often difficult. In this study, a magnetic resonance imaging (MRI) classification system was used to describe the bTME surgery according to pelvic compartments. METHODS Consecutive patients with primary rectal cancer operated with laparoscopic robot-assisted bTME were prospectively included for 2 years. All patients had tumors that threatened the mesorectal fascia, invaded adjacent organs, and/or involved metastatic pelvic lateral lymph nodes. Short-term clinical outcomes and oncological specimen quality were registered. Surgery was classified according to pelvic compartments resected. RESULTS Clear resection margins (R0 resection) were achieved in 95 out of 105 patients (90.5%). About 26% had Accordion Severity Grading System of Surgical Complications grade 3-4 complications and 15% required re-operations. About 7% were converted to open surgery. The number of compartments resected ranged from one to the maximum seven, with 83% having two or three compartments resected. All 10 R1 resections occurred in the lateral and posterior compartments. CONCLUSIONS The short-term clinical outcomes and oncological specimen quality after robot-assisted bTME surgery were comparable to previously published open bTME surgery. The description of surgical procedures using the Royal Marsden MRI compartment classification was feasible.

Abstract
Chronic skin lesions of the thigh (wounds, fistulas etc) are relatively uncommon, vis-à-vis, their notorious cousins over the distal limb. Even when present, the cause is usually obvious, mostly as trauma or a systemic affliction. We present an unusual case of chronic fistulas over the right thigh in a patient of carcinoma rectum for which anterior resection and an end colostomy was done 4 years earlier. Postsurgical pelvic abscesses finding their way into the thigh are a known entity, but they are usually accompanied by systemic/local features and their presentation is within a shorter time span. The novelty of our case lies in its manifestation (as a cluster of chronic fistulas and not a frank abscess), its late presentation as well as in the absence of any systemic/local inflammatory signs. Our primary objective is to educate wound physicians about the origin of such fistulas whenever they deal with patients who have had a preceding surgical intervention of the abdomen. In our humble opinion, this will ease out many diagnostic and management dilemmas, that such patients can potentially pose.

Endoscopic management of low output recurrent colonic fistula or leak after anterior resection for rectal cancer: a randomized controlled trial. Surg Endosc 2023:10.1007/s00464-023-10092-z. [PMID: 37145174 PMCID: PMC10338381 DOI: 10.1007/s00464-023-10092-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 04/19/2023] [Indexed: 05/06/2023]
Abstract
BACKGROUND Colonic anastomotic leak and fistula following anterior resection surgery for rectal cancer are associated with high mortality rates. The incidence of occurrence varies from 2 to 25% and it is difficult to accurately calculate the incidence of fistula and leak post anterior resection, as most of them are asymptomatic. Endoscopic management of fistula and leak has become the first line of management after conservative management in many gastrointestinal surgical centers with the advantages of being less invasive, shorter length of post-operative hospital stay, effective and rapid recovery in comparison to revision surgery. Effective endoscopic management for colonic fistula or leak depends on the clinical status of the patient and fistula characters (time-to-occur and size and site of defect), and device availability. METHODS This prospective randomized controlled clinical trial included all patients who developed the manifestations of low output recurrent colonic fistula or leak after colonic anterior resection for rectal cancer at Zagazig University Hospital between (December 2020 and August 2022). Sample size was 78 patients divided into two equal groups. Endoscopic group (EG): included 39 patients who underwent endoscopic management. Surgical group (SG): included 39 patients who underwent surgical management. RESULTS The investigators randomized eligible 78 patients into two groups: 39 patients in SG and 39 patients in EG. The median size of the fistula or leak was nine (range: 7-14) mm in EG, versus ten (range: 7-12) mm in SG. Clipping and Endo-stitch device were used in 24 patients versus 15 patients, respectively, in EG while primary repair with ileostomy, and resection & anastomosis were used in 15 patients versus 24 patients, respectively, in SG. Recurrence, abdominal collection, and mortality were the post procedure's complications with incidence of occurrence of 10.3, 7.7 and 0%, respectively, in EG versus 20.5, 20.5 and 2.6%, respectively, in SG. Excellent, good, and poor were the parameters for quality of life with incidence of occurrence of 43.6, 54.6 and 0%, respectively, in EG versus 28.2, 33.3 and 38.5%, respectively, in SG. Median hospital stay was one (range: 1-2) day in endoscopic group, and seven (range: 6-8) days in SG. CONCLUSION Endoscopic intervention may offer a successful modality in managing low output recurrent colonic fistula or leak after anterior resection for rectal cancer that did not respond to conservative measures in stable patients.

Operative blood loss adversely affects short and long-term outcomes after colorectal cancer surgery: results of a systematic review and meta-analysis. Tech Coloproctol 2023; 27:189-208. [PMID: 36138307 DOI: 10.1007/s10151-022-02701-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 09/01/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this meta-analysis was to assess the impact of operative blood loss on short and long-term outcomes following colorectal cancer surgery. METHODS A systematic literature review and meta-analysis were performed, from inception to the 10th of August 2020. A comprehensive literature search was performed on the 10th of August 2020 of PubMed MEDLINE, Embase, Science Citation Index Expanded, and Cochrane Central Register of Controlled Trials. Only studies reporting on operative blood loss and postoperative short term or long-term outcomes in colorectal cancer surgery were considered for inclusion. RESULTS Forty-three studies were included, reporting on 59,813 patients. Increased operative blood loss was associated with higher morbidity, for blood loss greater than 150-350 ml (odds ratio [OR] 2.09, p < 0.001) and > 500 ml (OR 2.29, p = 0.007). Anastomotic leak occurred more frequently for blood loss above a range of 50-100 ml (OR 1.14, p = 0.007), 250-300 ml (OR 2.06, p < 0.001), and 400-500 ml (OR 3.15, p < 0.001). Postoperative ileus rate was higher for blood loss > 100-200 ml (OR 1.90, p = 0.02). Surgical site infections were more frequent above 200-500 ml (OR 1.96, p = 0.04). Hospital stay was increased for blood loss > 150-200 ml (OR 1.63, p = 0.04). Operative blood loss was significantly higher in patients that suffered morbidity (mean difference [MD] 133.16 ml, p < 0.001) or anastomotic leak (MD 69.56 ml, p = 0.02). In the long term, increased operative blood loss was associated with worse overall survival above a range of 200-500 ml (hazard ratio [HR] 1.15, p < 0.001), and worse recurrence-free survival above 200-400 ml (HR 1.33, p = 0.01). Increased blood loss was associated with small bowel obstruction caused by colorectal cancer recurrence for blood loss higher than 400 ml (HR 1.97, p = 0.03) and 800 ml (HR 3.78, p = 0.02). CONCLUSIONS Increased operative blood loss may adversely impact short term and long-term postoperative outcomes. Measures should be taken to minimize operative blood loss during colorectal cancer surgery. Due to the uncertainty of evidence identified, further research, with standardised methodology, is required on this important subject.

Abstract
Purpose Recently, totally laparoscopic ileostomy reversal (TLAP) has received increasing attention and exhibited promising short-term outcomes. The aim of this study was to detail the learning process of the TLAP technique. Methods Based on our initial experience with TLAP from 2018, a total of 65 TLAP cases were enrolled. Demographics and perioperative parameters were assessed using cumulative sum (CUSUM), moving average, and risk-adjusted CUSUM (RA-CUSUM) analyses. Results The overall mean operative time (OT) was 94 min and the median postoperative hospitalization period was 4 days, and there was an estimated 10.77% incidence rate of perioperative complications. Three unique phases of the learning curve were derived from CUSUM analysis, and the mean OT of phase I (1-24 cases) was 108.5 min, that of phase II (25-39 cases) was 92 min, and that of phase III (40-65 cases) was 80 min, respectively. There was no significant difference in perioperative complications between these 3 phases. Similarly, moving average analysis indicated that the operation time was reduced significantly after the 20th case and reached a steady state after the 36th case. Furthermore, complication-based CUSUM and RA-CUSUM analyses indicated an acceptable range of complication rates during the whole learning period. Conclusion Our data demonstrated 3 distinct phases of the learning curve of TLAP. For an experienced surgeon, surgical competence in TLAP can be grasped at around 25 cases with satisfactory short-term outcomes.

Abstract
INTRODUCTION anastomotic leak (AL) after colectomy for colorectal cancer (CRC) is a life-threatening complication. This systematic review and meta-analysis aimed to evaluate the preoperative risk factors for AL in patients submitted to colectomy. METHODS the bibliographic search covered 15 years and 9 months, from 1st January 2005 to 19th October 2020 and was performed using PubMed, Cochrane Library, Scopus, Biblioteca Virtual em Saúde, Europe PMC and Web of Science databases. The inclusion criteria were cross-sectional, cohort and case-control studies on preoperative risk factors for AL (outcome). The Newcastle-Ottawa scale was used for bias assessment within studies. Meta-analysis involved the calculation of treatment effects for each individual study including odds ratio (OR), relative risk (RR) and 95% confidence intervals (95% CI) with construction of a random-effects model to evaluate the impact of each variable on the outcome. Statistical significance was set at p<0.05. RESULTS cross-sectional studies were represented by 39 articles, cohort studies by 21 articles and case-control by 4 articles. Meta-analysis identified 14 main risk factors for AL in CRC patients after colectomy, namely male sex (RR=1.56; 95% CI=1.40-1.75), smoking (RR=1.48; 95% CI=1.30-1.69), alcohol consumption (RR=1.35; 95% CI=1.21-1.52), diabetes mellitus (RR=1.97; 95% CI=1.44-2.70), lung diseases (RR=2.14; 95% CI=1.21-3.78), chronic obstructive pulmonary disease (RR=1.10; 95% IC=1.04-1.16), coronary artery disease (RR=1.61; 95% CI=1.07-2.41), chronic kidney disease (RR=1.34; 95% CI=1.22-1.47), high ASA grades (RR=1.70; 95% CI=1.37-2.09), previous abdominal surgery (RR=1.30; 95% CI=1.04-1.64), CRC-related emergency surgery (RR=1.61; 95% CI=1.26-2.07), neoadjuvant chemotherapy (RR=2.16; 95% CI=1.17-4.02), radiotherapy (RR=2.36; 95% CI=1.33-4.19) and chemoradiotherapy (RR=1.58; 95% CI=1.06-2.35). CONCLUSIONS important preoperative risk factors for colorectal AL in CRC patients have been identified based on best evidence-based research, and such knowledge should influence decisions regarding treatment.

[PMID: 36229306 DOI: 10.1016/j.asjsur.2022.09.107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 03/18/2022] [Accepted: 09/22/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND This study aimed to identify the risk factors for permanent stoma (PS) in patients who underwent sphincter-saving operations for rectal cancer. METHODS We retrospectively reviewed 597 consecutive patients with rectal cancer from January 2012 to December 2020 at Taipei Medical University Hospital. Univariate and multivariable analyses were used to analyze risk factors for PS. RESULTS After a mean follow-up of 47.3 months (range 7-114 months), 59 patients (15.1%) were alive with a PS, including 46 patients who did not undergo reversal surgery and 13 patients who underwent stoma re-creation after reversal surgery. The mean period between primary surgery and stoma reversal was 6.0 months. Multivariate analysis revealed that the risk factors for PS were local recurrence [odd ratio (OR), 25.58; 95% confidence interval (CI), 4.428-147.761; p < 0.001], perirectal abscess [OR, 154.34; 95% CI, 15.806 - >999; p < 0.001], anastomosis site stenosis [OR, 187.081; 95% CI, 22.193 - >999; p < 0.001], perineural invasion [OR, 4.782; 95% CI, 1.22-18.736; p = 0.025], and operation time (min) [OR, 1.008; 95% CI, 1.002-1.014; p = 0.01]. CONCLUSIONS Local recurrence, perirectal abscess, anastomosis site stenosis, perineural invasion, and operation time were independent risk factors for PS. Therefore, before a patient undergoes surgery for rectal cancer, surgeons should consider the possibility of the need for a PS, and patients should be informed before the operation that closure of the temporary stoma may not always be possible.

Chiarello MM, Fransvea P, Cariati M, Adams NJ, Bianchi V, Brisinda G. Anastomotic leakage in colorectal cancer surgery. Surg Oncol 2022; 40:101708. [PMID: 35092916 DOI: 10.1016/j.suronc.2022.101708] [Citation(s) in RCA: 50] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 01/11/2022] [Accepted: 01/20/2022] [Indexed: 02/05/2023]
Abstract
The safety of colorectal surgery for oncological disease is steadily improving, but anastomotic leakage is still the most feared and devastating complication from both a surgical and oncological point of view. Anastomotic leakage affects the outcome of the surgery, increases the times and costs of hospitalization, and worsens the prognosis in terms of short- and long-term outcomes. Anastomotic leakage has a wide range of clinical features ranging from radiological only finding to peritonitis and sepsis with multi-organ failure. C-reactive protein and procalcitonin have been identified as early predictors of anastomotic leakage starting from postoperative day 2-3, but abdominal-pelvic computed tomography scan is still the gold standard for the diagnosis. Several treatments can be adopted for anastomotic leakage. However, there is not a universally accepted flowchart for the management, which should be individualized based on patient's general condition, anastomotic defect size and location, indication for primary resection and presence of the proximal stoma. Non-operative management is usually preferred in patients who underwent proximal faecal diversion at the initial operation. Laparoscopy can be attempted after minimal invasive surgery and can reduce surgical stress in patients allowing a definitive treatment. Reoperation for sepsis control is rarely necessary in those patients who already have a diverting stoma at the time of the leak, especially in extraperitoneal anastomoses. In patients without a stoma who do not require abdominal reoperation for a contained pelvic leak, there are several treatment options, including laparoscopic diverting ileostomy combined with trans-anal anastomotic tube drainage, percutaneous drainage or recently developed endoscopic procedures, such as stent or clip placement or endoluminal vacuum-assisted therapy. We describe the current approaches to treat this complication, as well as the clinical tests necessary to diagnose and provide an effective therapy.

Abstract
RESUMO Objetivo: fístula anastomótica (FA) após colectomia para câncer colorretal (CCR) é complicação grave. Esta revisão sistemática e meta-análise avaliou os fatores de risco pré-operatórios para FA em pacientes submetidos à colectomia. Métodos: a pesquisa bibliográfica abrangeu 15 anos e 9 meses (1 de janeiro de 2005 - 19 de outubro de 2020), sendo utilizadas as plataformas PubMed, Cochrane Library, Scopus, Biblioteca Virtual em Saúde, Europe PMC e Web of Science. O critério de inclusão foram estudos transversais, coorte e caso-controle em fatores de risco pré-operatórios para FA (desfecho). A escala Newcastle-Ottawa foi usada para avaliação de viés dos estudos. A metanálise envolveu o cálculo dos efeitos de tratamento para cada estudo individualmente incluindo odds ratio (OR), risco relativo (RR) e intervalo de confiança de 95% (IC95%) com construção de modelo de efeitos aleatórios, para avaliar o impacto de cada variável (p<0,05). Resultados: foram selecionados 39 estudos transversais, 21 coortes e quatro casos-controle. A metanálise identificou 14 fatores de risco para FA em pacientes com CCR após colectomia, que são sexo masculino (RR=1,56; IC 95%=1,40-1,75), tabagismo (RR=1,48; IC 95%=1,30-1,69), alcoolismo (RR=1,35; IC 95%=1,21-1,52), diabetes mellitus (RR=1,97; IC 95%=1,44-2,70), doenças pulmonares (RR=2,14; IC 95%=1,21-3,78), doença pulmonar obstrutiva crônica (RR=1,10; IC 95%=1,04-1,16), doença coronariana (RR=1,61; IC 95%=1,07-2,41), doença renal crônica (RR=1,34; IC 95%=1,22-1,47), altas notas na escala ASA (RR=1,70; IC 95%=1,37-2,09), cirurgia abdominal prévia (RR=1,30; IC 95%=1,04-1,64), cirurgia de emergência (RR=1,61; IC 95%=1,26-2,07), quimioterapia neoadjuvante (RR=2,16; IC 95%=1,17-4,02), radioterapia (RR=2,36; IC 95%=1,33-4,19) e quimiorradioterapia (RR=1,58; IC 95%=1,06-2,35). Conclusões: importantes fatores de risco pré-operatórios para FA colorretais em pacientes com CCR foram identificados com base nas melhores pesquisas baseadas em evidências e esse conhecimento deve influenciar decisões relacionadas ao tratamento.

A systematic review of the literature assessing operative blood loss and postoperative outcomes after colorectal surgery. Int J Colorectal Dis 2022; 37:47-69.

Abstract
PURPOSE There is no consensus in the literature regarding the association between operative blood loss and postoperative outcomes in colorectal surgery, despite evidence suggesting a link. Therefore, this systematic review assesses the association between operative blood loss, perioperative and long-term outcomes after colorectal surgery. METHODS A literature search of MEDLINE, EMBASE, Science Citation Index Expanded and Cochrane was performed to identify studies reporting on operative blood loss in colorectal surgery. RESULTS The review included forty-nine studies reporting on 61,312 participants, with a mean age ranging from 53.4 to 78.1 years. The included studies demonstrated that major operative blood loss was found to be a risk factor for mortality, anastomotic leak, presacral abscess, and postoperative ileus, leading to an increased duration of hospital stay. In the long term, the studies suggest that significant blood loss was an independent risk factor for future small bowel obstruction due to colorectal cancer recurrence and adhesions. Studies found that survival was significantly reduced, whilst the risk of colorectal cancer recurrence was increased. Reoperation and cancer-specific survival were not associated with major blood loss. CONCLUSION The results of this systematic review suggest that major operative blood loss increases the risk of perioperative adverse events and has short and long-term repercussions on postoperative outcomes. Laparoscopic and robotic surgery, vessel ligation technology and anaesthetic considerations are essential for reducing blood loss and improving outcomes. This review highlights the need for further high quality, prospective, multicentre trials with a greater number of participants, and accurate and standardised methods of measuring operative blood loss.

Abstract
Objective Anastomotic leakage (AL) is the most serious postoperative complication following anterior resection for rectal cancer. We aimed to investigate the efficacy of active drainage for the management of AL. Methods This was a retrospective study using information from a database of patients who underwent colorectal resection without a defunctioning ileostomy at our center between September 2013 and January 2021. We identified 122 cases with definitive AL who did not require revision emergent laparotomy. Among these patients, we evaluated those who received active drainage to replace the original passive drainage. Results There were 62 cases in the active drainage group and 60 cases in the passive drainage group. The active drainage group had a shorter mean AL spontaneous resolution time (26.9 ± 3.3 vs. 32.2 ± 4.8 days) and lower average hospitalization costs (82,680.6 vs. 92,299.3 renminbi (RMB)) compared with the passive drainage group, respectively. Moreover, seven patients in the passive drainage group subsequently underwent diverting stoma to resolve the Al, while all ALs resolved spontaneously after replacing the passive drainage with active drainage. Conclusions Our study suggests that active drainage may accelerate the spontaneous resolution of AL.

Abstract
PURPOSE The purpose of this study was to determine the risk factors for the development of a permanent stoma in laparoscopic intersphincteric resection (LS-ISR) for ultralow rectal adenocarcinoma and to develop and validate a prediction model to predict the probability of permanent stoma after surgery. METHODS A primary cohort consisting of 301 consecutive patients who underwent LS-ISR was enrolled in this study. Multivariable logistic regression analysis was used to identify risk factors and develop the nomogram. The performance of the nomogram was assessed with respect to its calibration, discrimination, and clinical usefulness. An independent validation cohort contained 91 consecutive patients from January 2012 to January 2019. RESULTS The permanent stoma rate was 11.3% (34/301) in the primary cohort and 18.7% (17/91) in the validation cohort. Multivariable analysis revealed that nCRT (OR, 3.195; 95% CI, 1.169-8.733; P=0.024), ASA score of 3 (OR, 5.062; 95% CI, 1.877-13.646; P=0.001), distant metastasis (OR, 14.645; 95% CI, 3.186-67.315; P=0.001), and anastomotic leakage (OR, 11.308; 95% CI, 3.650-35.035; P<0.001) were independent risk factors for permanent stoma, and a nomogram was established. The AUCs of the nomogram were 0.842 and 0.858 in the primary and validation cohorts, respectively. The calibration curves showed good calibration in both cohorts. Decision curve analysis demonstrated that the nomogram was clinically useful. CONCLUSION We developed and validated a nomogram for ultralow rectal adenocarcinoma patients who underwent LS-ISR, and the nomogram could help surgeons identify which patients are at a higher risk of a permanent stoma after surgery.

Abstract
PURPOSE To investigate the usefulness of contrast-enhanced abdominal computed tomography (CECT) to predict clinically significant anastomotic leakage (CSAL) in patients who received colorectal cancer surgery with diverting ileostomy. METHODS In this retrospective cohort study, patients who underwent colorectal cancer surgery with diverting ileostomy from January 2014 to May 2018 and postoperative CECT were included. The performance of significant CECT features, identified using multivariable logistic regression, to predict CSAL was calculated. In subgroup analysis, the areas under the receiver operating characteristic curve (AUROCs) were compared between CECT and water-soluble contrast enema (WSCE) using DeLong's method. RESULTS Of 325 patients (median age, 58 years; 213 men), CECT was routinely performed to evaluate cancer status in 307 (94.5%), and CSAL was observed in 28 (8.6%). After multivariable adjustment, anastomotic mural defect (odds ratio [OR] 5.24; 95% confidence interval [CI] 1.77-15.51; p = 0.003), perianastomotic air (OR 7.28; 95% CI 1.82-29.17; p = 0.007) and ischemic colitis (OR 3.30; 95% CI 1.13-9.61; p = 0.029) were significantly associated with CSAL. The sensitivity, specificity, accuracy, and positive and negative predictive values of significant CECT features were 60.7%, 88.2%, 85.9%, 32.7%, and 96.0%, respectively. In subgroup analysis of 144 patients, the AUROC using significant CECT features (optimal sensitivity/specificity, 50.0%/90.4%) was comparable to that using WSCE (optimal sensitivity/specificity, 12.5%/97.8%) to predict CSAL (0.704 vs. 0.552, p = 0.085). CONCLUSION CECT performed after colorectal cancer surgery may be useful to assess anastomotic integrity before ileostomy closure, especially to negatively predict CSAL. In the presence of anastomotic mural defect, perianastomotic air, or ischemic colitis, WSCE may be recommended to exclude CSAL.

Abstract
Ileal diverticulum rarely causes pelvic abscess. Pelvic abscess rarely causes thigh phlegmon. Rupture of presacral abscess to extra-pelvic site carries high mortality. Intrapelvic pathology has to be considered in patients with thigh phlegmon.
Introduction Ileal diverticula usually remain asymptomatic. If complicated, they may present as intra-abdominal or pelvic abscess. Abscess formation in the presacral space is very rare. The rupture of abscess and spread of pus to extra-pelvic sites through anatomical structures of the pelvis is extremely rare. It carries high mortality if not diagnosed on time. Case presentation We report a case of 52-year-old woman presented with thigh phlegmon and septic condition. The CT scan revealed free air in the left leg and pelvic presacral fluid collection descending to extra-pelvic direction through the greater sciatic notch. Moreover, ileal fistula to presacral abscess was suspected. Multiple incisions and fasciotomies were urgently performed to treat thigh phlegmon. Subsequently, laparotomy was carried out and ileal fistula was excised. Histological examination of the surgical specimen demonstrated that the fistula to presacral abscess has formed due to perforated ileal diverticulum. 3 years after the surgery the patient remains healthy without recurrence. Discussion Rupture of presacral abscess to extra-pelvic site due to ileal diverticulum fistula is an extremely rare case, to our best knowledge, never reported in literature. Due to a rare occurrence and early septic complications if diagnosed late, this condition carries a high mortality rate. Conclusion Intrapelvic pathology must be considered in patients with thigh phlegmon in order to prevent complications and associated mortality.

Abstract
BACKGROUND Anastomotic leaks are a dreaded complication after colorectal surgery. Although anastomotic leak is often used as a metric to compare patient outcomes, a standard definition does not exist. MATERIALS AND METHODS A web-based survey was developed and distributed to US surgeons. Respondents were queried on the definition of anastomotic leaks using a 5-point Likert scale to rate different scenarios related to colorectal surgery. RESULTS Of potential 2209 respondents, 649 (29%) responded to the survey. The majority of respondents was men (76%) and practiced colon and rectal surgery as their primary specialty (89%). Contrast extravasation at the anastomosis, regardless of timing related to the surgery, is the clinical scenario with greatest consensus (>85%). 50% of surgeons do not believe that an abscess near the anastomosis in an asymptomatic patient defines a leak. CONCLUSIONS These results highlight the pressing need for standardization of the anastomotic leak definition given the implications on outcomes measurement, research trials, and health care reimbursement.

Abstract
PURPOSE Intraoperative estimated blood loss (EBL) is often reported in nearly all surgical papers; however, there is no consensus regarding its measurement. The aim of this study was to determine whether EBL (ml) is as reliable and reproducible in predicting complications as a simple binary grading of EBL. METHODS All consecutive patients undergoing colectomies between January 2015 and December 2018 were included. EBL was assessed prospectively by the surgeon and anaesthesiologist in ml and with a binary scale: bleeding "as usual" versus "more than usual" by the surgeon. Differences between pre- and post-operative haemoglobin levels (ΔHb g/dl) were correlated to EBL. Blood loss impact on 30-day postoperative morbidity was analysed. RESULTS A total of 270 patients were included, with a mean age of 65 years (SD 17). Mean EBL documented by surgeons correlated to EBL by anaesthesiologists (79.5 ml, SD 99 vs. 84.5 ml, SD 118, ϱ = 0.926, p < 0.001). Surgeons and anaesthesiologists' EBL correlated also with ΔHb (ϱ = - 0.273, p = 0.01 and ϱ = - 0.344, p = 0.01, respectively). Patient with surgeon EBL ≥ 250 ml or graded as "more than usual" bleeding had significantly more severe complications (8% vs. 20%, p = 0.02 and 8% vs. 27%, p = 0.001, respectively). CONCLUSION Anaesthesiologist and surgeon's EBL correlated with ΔHb. Simple grading of blood loss as "usual" and "more than usual" predicted severe complications and higher mortality rates. This simple binary grading of blood loss in colon surgery could be an alternative to the estimation of blood loss in ml as it is easy to apply but needs to be validated externally.

Abstract
BACKGROUND Colonic anastomotic leaks are associated with significant morbidity and mortality. Whereas small case series suggest that fully covered self-expandable metal stents (FCSEMS) are effective, no larger studies have examined the impact of combination endoscopic therapy on colonic anastomotic leaks. METHODS Our retrospective cohort study reviewed 51 patients undergoing endoscopic therapy for colonic anastomotic leaks between 2011 and 2018. Patients receiving combination therapy involving FCSEMS plus local closure (n = 24) were compared with patients receiving FCSEMS alone (n = 18) or endoscopic suturing alone (n = 9). The primary outcomes were technical and clinical success (resolution of leak, removal of percutaneous drains, avoidance of surgical reoperation, and reversal of temporary diversion). RESULTS Clinical success was achieved in 55 % of patients. Clinical success was achieved in 18/24 patients (75 %) with combination therapy compared with 6/18 patients receiving FCSEMS alone (33 %, adjusted risk ratio [RR] 2.16, 95 % confidence interval [CI] 1.10 - 4.24; P = 0.02) and 4 /9 patients undergoing endoscopic suturing alone (44 %, RR 1.91, 95 %CI 0.84 - 4.31; P = 0.10). Stent migration occurred in 40 % of patients. CONCLUSIONS This large series demonstrates that combination therapy was associated with a higher rate of clinical success, and future prospective studies are warranted.

Abstract
Objective Our objective was to investigate the association between anastomotic leakage (AL) and hyponatremia after colorectal cancer surgery. Methods All anastomoses in colorectal cancer surgery performed in our hospital between January 2015 and December 2017 were retrospectively identified. According to the diagnostic criteria of AL, the patients were divided into an AL group and a no anastomotic leakage (NAL) group. Results We reviewed records of 498 consecutive colorectal cancer patients. The total incidence of AL was 5.4%. Postoperative serum sodium levels differed significantly: 137.63 ± 4.29 and 139.81 ± 3.41 mmol/L in the AL and NAL groups, respectively. By using area under the receiver-operating characteristic (auROC) curves, we determined the optimum postoperative serum sodium cut-off to be 139.5 mmol/L and redefined hyponatremia as postoperative serum sodium <139.5 mmol/L. Redefined hyponatremia had an auROC of 0.65, corresponding to a 97.2% negative predictive value. The negative predictive value reached 99.1% when serum sodium level was combined with leukocytosis. Multivariable analysis found that redefined hyponatremia (odds ratio, 1.176) was an independent predictive factor for AL. Conclusions Redefined hyponatremia has good negative predictive value for AL diagnosis after colorectal cancer surgery and could be used as a marker to exclude the diagnosis.

Abstract
Gastrointestinal leaks and fistulae are serious, potentially life threatening conditions that may occur with a wide variety of clinical presentations. Leaks are mostly related to post-operative anastomotic defects and are responsible for an important share of surgical morbidity and mortality. Chronic leaks and long standing post-operative collections may evolve in a fistula between two epithelialized structures. Endoscopy has earned a pivotal role in the management of gastrointestinal defects both as first line and as rescue treatment. Endotherapy is a minimally invasive, effective approach with lower morbidity and mortality compared to revisional surgery. Clips and luminal stents are the pioneer of gastrointestinal (GI) defect endotherapy, whereas innovative endoscopic closure devices and techniques, such as endoscopic internal drainage, suturing system and vacuum therapy, has broadened the indications of endoscopy for the management of GI wall defect. Although several endoscopic options are currently used, a standardized evidence-based algorithm for management of GI defect is not available. Successful management of gastrointestinal leaks and fistulae requires a tailored and multidisciplinary approach based on clinical presentation, defect features (size, location and onset time), local expertise and the availability of devices. In this review, we analyze different endoscopic approaches, which we selected on the basis of the available literature and our own experience. Then, we evaluate the overall efficacy and procedural-specific strengths and weaknesses of each approach.

Abstract
BACKGROUND Despite the emerging knowledge about colorectal anastomotic leakage (CAL) through the increasing number of clinical and experimental studies, there is no generally accepted definition of CAL. Because of the wide variety of definitions used in literature, comparison of study outcomes and quality of care is complicated.
AIM To reach consensus on the definition of CAL using a modified Delphi method.
METHODS The RAND/UCLA appropriateness method was used. The expert panel consisted of international colorectal surgeons and researchers who had published three or more articles about CAL. The consensus process consisted of two online distributed questionnaires and a third round with a recommendation. In the questionnaires participants were asked to rate the appropriateness of statements using a 1-9 Likert scale. Consensus was defined as a panel median between 1-3 or 7-9 without disagreement. In the final round a recommendation was formed regarding the definition of CAL and the expert panel was asked if they agreed or disagreed.
RESULTS Twenty-three authors participated in the first round and twenty-one finished the second round. After two rounds consensus was reached on 37 items (80%) in nine different categories. The International Study Group of Rectal Cancer definition is the most frequently advised general definition by our panel. Consensus was reached regarding the clinical symptoms of CAL, which serum markers contributes to the suspicion of CAL, which radiological and perioperative findings should be considered as CAL, which grading system is appropriate and if there should be a range of postoperative days in the definition. Eventually, 19 experts completed all three rounds of which 16 (84%) agreed with our final recommendations for the definition of CAL.
CONCLUSION A consensus-based recommendation for the definition of CAL was formed using our modified Delphi method that can be widely incorporated in the field.

Abstract
Multimodal strategies have been implemented for locally recurrent rectal cancer scheduled for complete surgical resection. Irradiation and systemic therapy have been added to improve the oncological outcome, as surgery alone was associated with a poor prognosis. Intraoperative irradiation (IORT) is a component of irradiation intensification. Long-term cancer control and a higher survival rate were consistently reported in patients who had IORT as a component of their multidisciplinary treatment. The experience reported by expert IORT groups is reviewed and recommendations to guide clinical practice are explained in detail.

Abstract
OBJECTIVES Anastomotic leakage (AL) after anterior resection always leads to longer hospital stays, decreased quality of life and even increased mortality. Despite extensive research, no consensus on the world well-concerned surgical-related risk factors exists. We therefore conducted a meta-analysis of the available published literature to identify the effects of surgical-related risk factors for AL after anterior resection for rectal cancer, hoping to provide more information and improved guidance for clinical workers managing patients with rectal cancer who are at a high risk for AL. METHODS In this study, the relevant articles were systematically searched from EMBASE, MEDLINE, PubMed, WangFang (Database of Chinese Ministry of Science & Technology), Chinese National Knowledge Infrastructure Database and China Biological Medicine Database. The pooled odds ratio (OR) with 95% confidence interval (95% CI) were calculated. Meta-analysis was performed using of RevMan 5.3 software. RESULTS A total of 26 studies met the inclusion criteria and comprised 34238 cases. Analysis of these 26 studies showed that no defunctioning stoma was highly correlated with AL (pooled OR = 1.28, 95%CI: 1.05-1.57, P = 0.01, random effect), and intraoperative blood transfusion was significantly associated with AL (pooled OR = 1.64, 95%CI: 1.34-2.02, P = 0.02, random effect). However, the AL was not associated with type of anastomosis, type of surgery, technique of anastomosis, level of inferior mesenteric artery ligation, operation time and splenic flexure mobilization. CONCLUSIONS Depend on this meta-analysis, no defunctioning stoma and intraoperative blood transfusion are the major surgical-related risk factors for AL after resection for rectal cancer. Because of the inherent limitations of the research, future prospective randomized controlled trials will need to confirm this conclusion.

Abstract
High-throughput liquid chromatography-mass spectrometry (LC-MS)-based metabolomics can provide the holistic analysis of the low molecular weight endogenous metabolites in cells and reflect the changes of cellular regulation and metabolic pathways. Our study designed to reveal the potentially pharmacological effects of dioscin on SW480 rectal cancer cells using nontargeted metabolomics method to probe into small molecular metabolites and pathway changes. After the cell assay of proliferation, apoptosis, migration, and invasion, the dioscin-treated cell samples were prepared for nontargeted metabolomics analysis based on LC-MS tool to describe the metabolic profiles. Dioscin has prevented cell proliferation and accelerated cell apoptosis, and it also inhibited the SW480 rectal cancer cells' migration and invasion. A total of 22 metabolites were selected as promising biomarkers of pharmacological reaction of dioscin to rectal cancer, and eight highly correlated pathways including D-glutamine and D-glutamate metabolism, pyruvate metabolism, arachidonic acid metabolism, phenylalanine metabolism, tryptophan metabolism, glycolysis or gluconeogenesis, citrate cycle (TCA cycle), and butanoate metabolism were identified. It showed that strategies based on cell metabolomics are helpful tools to discover the small molecular metabolites to elucidate the action mechanism of drug.

Abstract
BACKGROUND Preoperative radiochemotherapy is widely used in locally advanced rectal cancer. It can improve local control of rectal cancer. However, some researchers believe it increases the incidence of surgical complications. They doubt its safety. Patients with locally advanced rectal cancer receive three different treatments in our hospital, including long-course radiochemotherapy, short-course radiotherapy, and surgery directly. We can compare their differences in postoperative complications.
AIM To investigate surgical complications caused by different preoperative radiotherapy regimens.
METHODS We retrospectively analyzed 1197 patients admitted between 2008 and 2010 with locally advanced rectal cancer. Three hundred and forty-six patients were treated with preoperative long-course radiochemotherapy (25 × 2 Gy) followed by total mesorectal excision (TME) 6–8 wk later, and 259 patients received short-course radiotherapy (10 × 3 Gy) and subsequently TME 7–10 d later. The remaining 592 patients underwent TME alone without neoadjuvant therapy. According to Clavien–Dindo classification, surgical complications were evaluated for up to 30 d after discharge from hospital.
RESULTS There were no deaths in 30 d in all groups after treatment. The major complications were anastomotic leakage and perineal wound complications. The results suggested that both long-course [odds ratio (OR) = 3.624, 95% confidence interval (CI): 1.689–7.775, P = 0.001] and short-course (OR = 5.150, 95%CI: 1.828–14.515, P = 0.002) radiotherapy were associated with anastomotic leakage. Temporary ileostomy was a protective factor for anastomotic leakage (OR = 6.211, 95%CI: 2.525–15.385, P < 0.001). The severity of anastomotic leakage did not increase in patients following preoperative radiotherapy (P = 0.411). Compared with TME alone, short-course radiotherapy was associated with an increase in perineal wound complications (OR = 5.565, 95%CI: 2.203–14.057, P < 0.001), but long-course radiotherapy seemed safe regarding this complication (OR = 1.692, 95%CI: 0.651–4.394, P = 0.280). Although the severity of perineal wound complications increased in patients following short-course radiotherapy (P < 0.001), additional intervention was not necessary.
CONCLUSION Radiotherapy increased the incidence but not severity of anastomotic leakage. Short-course radiotherapy was also accompanied with perineal wound complications, but intervention appeared unnecessary to ameliorate the complications.

Abstract
BACKGROUND Anastomotic complications following colorectal surgery are associated with significant morbidity and mortality. For patients in whom systemic sepsis is absent or well controlled, minimal access techniques, such as endoscopic therapies, are being increasingly employed to reduce the morbidity of surgical re-intervention. In this review, we aim to assess the utility of endoscopic management in the acute setting of colorectal anastomotic complications, focusing on anastomotic leak. METHOD A literature search was performed for published full text articles using the PubMed, Cochrane and Scopus databases using the search criteria string "colorectal anastomotic ("leak" OR "bleed"), "endoscopy", endoscopic management". Additional papers were detected by scanning the references of relevant papers. Data were extracted from each study by two authors onto a dedicated pro-forma. Given the nature of the data extracted, no meta-analysis was performed. RESULTS A total of 89 papers were identified, 16 of which were included in this review; an additional 14 papers were obtained from reference searches. In patients who are not physiologically compromised, there are promising data regarding the salvage rate of stents, over-the-scope endoscopic clips, vacuum therapy and fibrin glue in the early management of colorectal anastomotic leak. There is no consensus regarding the optimal approach, and data to assist the physician in patient selection are lacking. Whilst data on salvage (i.e. healing and avoidance of surgery) are well understood, no data on functional outcomes are reported. CONCLUSION Endoscopic therapy in the management of stable patients with colorectal anastomotic leaks appears safe and in selected patients is associated with high rates of technical success. Challenges remain in selecting the most appropriate strategy, patient selection, and understanding the functional and long-term sequelae of this approach. Further evidence from large prospective cohort studies are needed to further evaluate the role of these novel strategies.

Abstract
Introduction Protective loop ileostomy (PLI) is used to reduce the anastomotic leak rate after resection of the rectum. It is an effective, yet burdensome procedure contradicting the aims of enhanced recovery after surgery (ERAS) by slowing down recovery. Early closure (EC) of the PLI has the potential to change the situation, and it should become part of ERAS. Aim To analyze the effectiveness of EC in ERAS patients. Material and methods A randomized clinical trial was performed between October the 1st, 2016 and December the 31st, 2017. Fifty-eight adult patients (24 females, 34 males, mean age: 55.7 and 56.2) operated on for rectal carcinoma according to the ERAS protocol with PLI were randomly assigned to the late (L) or early (E) closure group (14 days after discharge). Time to start adjuvant chemotherapy, complication rate, and health care costs were analyzed. Results There were no significant differences between groups regarding the length of surgery (83.2 ±15.9 vs. 87.1 ±21.7 min, in E and L, respectively), intraoperative blood loss (15.2 ±7.5 vs. 17.3 ±11.1 ml, respectively), median hospital stay, or the time to pass flatus and stool. The difference in the time needed to start the adjuvant treatment (38.7 ±5.7 vs. 33.2 ±5.8 days, p < 0.01), was compensated by the reduction of time living with a stoma (17.2 vs. 299.0 days) and health care costs: (43.68 vs. 698.42 USD). Conclusions Early closure is a safe and effective therapeutic approach, improving the recovery. Therefore it should be implemented as part of the ERAS protocol for rectal cancer patients.

Abstract
The endoscopic management armamentarium of gastrointestinal disruptions including perforations, leaks, and fistulas has slowly but steadily broadened in recent years. Previously limited to surgical or conservative medical management, innovations in advanced endoscopic techniques like natural orifice transluminal endoscopic surgery (NOTES) have paved the path towards development of endoscopic closure techniques. Early recognition of a gastrointestinal defect is the most important independent variable in determining successful endoscopic closure and patient outcome. Some devices including through the scope clips and stents have been well studied for other indications and have produced encouraging results in closure of gastrointestinal perforations, leaks and fistulas. Over the scope clips, endoscopic sutures, vacuum therapy, glue, and cardiac device occluders are other alternative techniques that can be employed for successful endoscopic closure.

Abstract
Transmural defects of the gastrointestinal tract can be classified into 3 distinct entities-leak, perforation, and fistula. Each arises from different mechanisms and is managed accordingly. Leaks occur most often after surgery, while perforations occur most often after flexible endoscopic maneuvers. Fistulae arise from a variety of mechanisms, such as an evolution from surgical leaks, as well as from specific disease states. Endoscopic management plays a vital role in the treatment of transmural defects as long as the region of interest can be accessed with the appropriate endoscopic accessories. Endoscopic approaches can be broadly classified into those that provide closure and those that provide diversion of luminal contents. With advances in technology, a myriad of devices and accessories are available that allow a tailored approach. Endoscopic approaches to leaks, perforations, and fistulae are discussed in this review.

Abstract
OBJECTIVES Little is known about late detected anastomotic leakage after low anterior resection for rectal cancer, and the proportion of leakages that develops into a chronic presacral sinus. METHODS In this collaborative snapshot research project, data from registered rectal cancer resections in the Dutch Surgical Colorectal Audit in 2011 were extended with additional treatment and long-term outcome data. Independent predictors for anastomotic leakage were determined using a binary logistic model. RESULTS A total of 71 out of the potential 94 hospitals participated. From the 2095 registered patients, 998 underwent a low anterior resection, of whom 88.8% received any form of neoadjuvant therapy. Median follow-up was 43 months (interquartile range 35-47). Anastomotic leakage was diagnosed in 13.4% within 30 days, which increased to 20.0% (200/998) beyond 30 days. Nonhealing of the leakage at 12 months was 48%, resulting in an overall proportion of chronic presacral sinus of 9.5%. Independent predictors for anastomotic leakage at any time during follow-up were neoadjuvant therapy (odds ratio 2.85; 95% confidence interval 1.00-8.11) and a distal (≤3 cm from the anorectal junction on magnetic resonance imaging) tumor location (odds ratio 1.88; 95% confidence interval 1.02-3.46). CONCLUSIONS This cross-sectional study of low anterior resection for rectal cancer in the Netherlands in 2011, with almost routine use of neoadjuvant radiotherapy, shows that one third of anastomotic leakages is diagnosed beyond 30 days, and almost half of the leakages eventually do not heal. Chronic presacral sinus is a significant clinical problem that deserves more attention.

Use of a nomogram to predict the closure rate of diverting ileostomy after low anterior resection: A retrospective cohort study. Int J Surg 2017; 47:83-88.

Abstract
INTRODUCTION Although temporary ileostomy is widely used to prevent complications due to anastomotic leakage after middle and low rectal cancer surgery, some patients fail to achieve stoma closure after primary surgery. The aim of this study was to identify the risk factors for permanent stoma following low anterior resection (LAR) or intersphincteric resection (ISR) with a temporary ileostomy for rectal cancer, while focusing on the time course, to develop a nomogram that can predict the rate of unreversed ileostomy 1 year after initial surgery. METHOD A total of 212 consecutive rectal cancer patients who underwent LAR or ISR with or without a temporary stoma between 2012 and 2015 at the University of Tokyo Hospital were retrospectively reviewed. Data analyses were performed using JMP Pro 11.0 and R 3.0.1 with rms and Hmisc packages to identify the risk factors for diverting ileostomy resulting in un-reversed stoma, and to develop a nomogram using these factors. RESULTS Among 212 patients, diverting ileostomy and colostomy were performed in 116 and 11 patients, respectively, and a stoma was not created in 85 patients. Among the ileostomy cases, 94 underwent stoma reversal, and the median interval from initial surgery to stoma closure was 6.9 months. Three patients eventually underwent stoma re-creation, and hence, 25 patients had permanent stoma. The following variables were correlated with the stoma non-reversal rate and were included in the nomogram: depth of invasion (p = 0.02), presence of metastatic organs (p = 0.07), and preoperative chemoradiotherapy (p = 0.03). The nomogram C-index was 0.612, indicating moderate predictive ability. CONCLUSIONS The most common factors preventing stoma closure included distant metastasis or rectal cancer recurrence. The nomogram developed in the present study can help identify rectal cancer patients with high risk of stoma non-reversal.

Abstract
Introduction Non-healing of anastomotic leakage can be observed in up to 50% after total mesorectal excision for rectal cancer. This study investigates the efficacy of early transanal closure of anastomotic leakage after pre-treatment with the Endosponge® therapy. Methods In this prospective, multicentre, feasibility study, transanal suturing of the anastomotic defect was performed after vacuum-assisted cleaning of the presacral cavity. Primary outcome was the proportion of patients with a healed anastomosis at 6 months after transanal closure. Secondary, healing at last follow-up, continuity, direct medical costs, functionality and quality of life were analysed. Results Between July 2013 and July 2015, 30 rectal cancer patients with a leaking low colorectal anastomosis were included, of whom 22 underwent neoadjuvant radiotherapy. Median follow-up was 14 (7–29) months. At 6 months, the anastomosis had healed in 16 (53%) patients. At last follow-up, anastomotic integrity was found in 21 (70%) and continuity was restored in 20 (67%) patients. Non-healing at 12 months was observed in 10/29 (34%) patients overall, and in 3/14 (21%) when therapy started within three weeks following the index operation. Major LARS was reported in 12/15 (80%) patients. The direct medical costs were €8933 (95% CI 7268–10,707) per patient. Conclusion Vacuum-assisted early transanal closure of a leaking anastomosis after total mesorectal excision with 73% preoperative radiotherapy showed that acceptable anastomotic healing rates and stoma reversal rates can be achieved. Early diagnosis and start of treatment seems crucial.

Abstract
Anastomotic leak in the gastrointestinal tract is one of the most important complications of resection. They are the main cause of reoperation, their occurrence worsens the prognosis of the patient, increasing the proportion of direct mortality, as well as being a significant risk factor for recurrence of cancer. The risk of leaks within the gastrointestinal tract is greatly varied, depending on the location and extent of the resection, but also on patient, disease or a surgical procedure, including surgeon. To determine the potential risk of leakage can be significant for introduction some prophylactic actions. Some of them have the character of general recommendations, as proper nutrition of the patient in the perioperative period, while another part is directly connected to the surgical procedure. The second group includes protective stoma, the use of tissue glues, insertion transrectal drain for rectal anastomosis decompression, the use of stents or the use of collagen matrix coated with fibrinogen and thrombin. Important to reduce the proportion of leaks can be more precise and targeted prophylactic recommendations, based on the individualized determination of risk factors leaks. Further research for this purpose are necessary for this purpose, the big hope can be associated with data obtained through mobile applications.

Abstract
Background An anastomotic leak (AL) after colorectal surgery is one major reason for postoperative morbidity and mortality. There is growing evidence that AL affects short and long term outcome. This prospective German multicentre study aims to identify risk factors for AL and quantify effects on short and long term course after rectal cancer surgery. Methods From 1 January 2000 to 31 December 2010 381 hospitals attributed patients to the prospective multicentre study Quality Assurance in Colorectal Cancer managed by the Otto-von-Guericke-University Magdeburg (Germany). Included were 17 867 patients with histopathologically confirmed rectal carcinoma and primary anastomosis. Risk factor analysis included 13 items of demographic patient data, surgical course, hospital volume und tumour stage. Results In 2 134 (11.9%) patients an AL was diagnosed. Overall hospital mortality was 2.1% (with AL 7.5%, without AL 1.4%; p < 0.0001). In multivariate analysis male gender, ASA-classification ≥III, smoking history, alcohol history, intraoperative blood transfusion, no protective ileostomy, UICC-stage and height of tumour were independent risk factors. Overall survival (OS) was significantly shorter for patients with AL (UICC I-III; UICC I, II or III - each p < 0.0001). Disease free survival (DFS) was significantly shorter for patients with AL in UICC I-III; UICC II or UICC III (each p < 0.001). Rate of local relapse was not significantly affected by occurrence of AL. Conclusion In this study patients with AL had a significantly worse OS. This was mainly due to an increased in hospital mortality. DFS was also negatively affected by AL whereas local relapse was not. This emphasizes the importance of successful treatment of AL related problems during the initial hospital stay.

Abstract
Laparoscopic rectal surgery has demonstrated its superiority over the open approach, however it still has some technical limitations that lead to the development of robotic platforms. Nevertheless the literature on this topic is rapidly expanding there is still no consensus about benefits of robotic rectal cancer surgery over the laparoscopic one. For this reason a review of all the literature examining robotic surgery for rectal cancer was performed. Two reviewers independently conducted a search of electronic databases (PubMed and EMBASE) using the key words “rectum”, “rectal”, “cancer”, “laparoscopy”, “robot”. After the initial screen of 266 articles, 43 papers were selected for review. A total of 3013 patients were included in the review. The most commonly performed intervention was low anterior resection (1450 patients, 48.1%), followed by anterior resections (997 patients, 33%), ultra-low anterior resections (393 patients, 13%) and abdominoperineal resections (173 patients, 5.7%). Robotic rectal surgery seems to offer potential advantages especially in low anterior resections with lower conversions rates and better preservation of the autonomic function. Quality of mesorectum and status of and circumferential resection margins are similar to those obtained with conventional laparoscopy even if robotic rectal surgery is undoubtedly associated with longer operative times. This review demonstrated that robotic rectal surgery is both safe and feasible but there is no evidence of its superiority over laparoscopy in terms of postoperative, clinical outcomes and incidence of complications. In conclusion robotic rectal surgery seems to overcome some of technical limitations of conventional laparoscopic surgery especially for tumors requiring low and ultra-low anterior resections but this technical improvement seems not to provide, until now, any significant clinical advantages to the patients.

Abstract
BACKGROUND High morbidity, increased mortality, and impaired long-term oncologic outcome have been reported after deep surgical site infection (SSI) in rectal cancer surgery. The rate, risk factors and consequences of deep SSI after (chemo)radiotherapy [(C)RT], and surgery for locally advanced rectal cancer (LARC) in a tertiary university hospital single centre cohort of 540 patients are presented. METHODS Patients with LARC, operated between January 1, 2007 and December 31, 2015, were identified in the institutional prospective database. All patients had tumours threatening the mesorectal fascia or invading adjacent organs, with a high rate of T4 tumours (60 %), and all received (C)RT. Risk factors for deep SSI were calculated by multivariable logistic regression analysis. Morbidity data were assessed. Overall survival (OS) and disease-free survival (DFS) between patients with or without deep SSI were estimated. RESULTS Of 540 patients, 104 (19 %) experienced a deep SSI, with the highest rate in the abdominoperineal resection (APR) group with 25 %. APR, good response to (C)RT (low tumour regression grade), age, and operative blood loss were identified as significant (P < 0.05) risk factors for deep SSI in multivariable analysis. No difference was found in OS (P = 0.995) or DFS (P = 0.568). Hospital stay increased with 5 days (P < 0.001), and complete wound healing at the 3-month follow-up decreased from 86 to 45 % (P < 0.001) after deep SSI. CONCLUSIONS Deep SSI is a frequent and major complication after rectal surgery for LARC, with high morbidity, increased hospital stay and protracted wound healing. Interestingly, deep SSI did not influence long-term oncologic outcome.

Abstract
UNLABELLED An emerging strategy to improve adhesiveness of biomaterials in wet conditions takes inspiration from the adhesive features of marine mussel, which reside in the chemical reactivity of catechols. In this work, a catechol-bearing molecule (dopamine) was chemically grafted onto alginate to develop a polysaccharide-based membrane with improved adhesive properties. The dopamine-modified alginates were characterized by NMR, UV spectroscopy and in vitro biocompatibility. Mechanical tests and in vitro adhesion studies pointed out the effects of the grafted dopamine within the membranes. The release of HA from these resorbable membranes was shown to stimulate fibroblasts activities (in vitro). Finally, a preliminary in vivo test was performed to evaluate the adhesiveness of the membrane on porcine intestine (serosa). Overall, this functionalized membrane was shown to be biocompatible and to possess considerable adhesive properties owing to the presence of dopamine residues grafted on the alginate backbone. STATEMENT OF SIGNIFICANCE This article describes the development of a mussels-inspired strategy for the development of an adhesive polysaccharide-based membrane for wound healing applications. Bioadhesion was achieved by grafting dopamine moieties on the structural component on the membrane (alginate): this novel biomaterial showed improved adhesiveness to the intestinal tissue, which was demonstrated by both in vitro and in vivo studies. Overall, this study points out how this nature-inspired strategy may be successfully exploited for the development of novel engineered biomaterials with enhanced bioadhesion, thus opening for novel applications in the field of general surgery.

Abstract
Anastomotic leak continues to be a dreaded complication after colorectal surgery, especially in the low colorectal or coloanal anastomosis. However, there has been no consensus on the management of the low colorectal anastomotic leak. Currently operative procedures are reserved for patients with frank purulent or feculent peritonitis and unstable vital signs, and vary from simple fecal diversion with drainage to resection of the anastomosis and closure of the rectal stump with end colostomy (Hartmann’s procedure). However, if the patient is stable, and the leak is identified days or even weeks postoperatively, less aggressive therapeutic measures may result in healing of the leak and salvage of the anastomosis. Advances in diagnosis and treatment of pelvic collections with percutaneous treatments, and newer methods of endoscopic therapies for the acutely leaking anastomosis, such as use of the endosponge, stents or clips, have greatly reduced the need for surgical intervention in selected cases. Diverting ileostomy, if not already in place, may be considered to reduce fecal contamination. For subclinical leaks or those that persist after the initial surgery, endoluminal approaches such as injection of fibrin sealant, use of endoscopic clips, or transanal closure of the very low anastomosis may be utilized. These newer techniques have variable success rates and must be individualized to the patient, with the goal of treatment being restoration of gastrointestinal continuity and healing of the anastomosis. A review of the treatment of low colorectal anastomotic leaks is presented.

Abstract
Colostomy reversals can be technically challenging and linked to significant morbidity. There is sparse evidence that evaluates outcomes after colostomy reversals performed by acute care surgeons. We performed a review of 61 colostomy reversals from January 2011 to January 2014. Colostomies for acute diverticulitis were predominate, n = 32 (52%). Traumatic colorectal injuries were n = 15, 25 per cent. Colorectal cancer was n = 8, 13 per cent. Sigmoid volvulus accounted for n = 2 cases. Abdominal sepsis from adhesions was n = 3. A rectal foreign body was for n = 1 case. The time to reversal was 360 ± 506 days. Completion of reversals was successful in 90 per cent of cases and protecting stoma use was in n = 12, (22%). Surgical site infections occurred in n = 20, patients (32%). Surgical site infections were prevalent in obese patients, (55%). Anastomotic leaks (ALs) occurred at 12 per cent, and were prevalent in obese, [obese (22%) vs nonobese (8%), P = 0.1]. The majority of AL n = 6, (85%) were in acute diverticulitis and trauma. There were no ALs in cases with protective diversion. No deaths occurred. The elective nature of colostomy reversals does not imply low morbidity. Obesity and major inflammatory processes were associated with major surgical complications. These data suggest that protective stomas should be applied liberally, particularly in high-risk cases.
