Abstract
This case involves a 53-year-old male who was diagnosed with stenotic ascending colon cancer and peritoneal metastatic deposits. He was initially planned for cytoreductive surgery and heated intraperitoneal chemotherapy (CRS and HIPEC), along with resection of the primary tumor in the form of right hemicolectomy. Intraoperatively, the disease was found to be more extensive than anticipated. Consequently, the plan was modified to include debulking right hemicolectomy with hand-sewn ileocolic anastomosis and extensive peritoneal procedures. Postoperatively, he experienced an anastomotic leak, leading to another laparotomy. However, due to anatomical challenges, creating a stoma was considered unsafe. Therefore, innovative interventions were performed, including controlling the anastomotic defect with a 30Fr Foley catheter without disrupting the anastomosis. A collaborative effort from various medical teams facilitated the patient's discharge home after an extended stay in the critical care unit (CCU).

Abstract
BACKGROUND It is unclear how early- and delayed-onset organ/space surgical site infections (SSIs) affect the long-term prognosis of patients with colorectal cancer, who are potential candidates for adjuvant chemotherapy. This study aimed to investigate the association between the timing of SSI onset and clinical outcome. METHODS This retrospective, multicenter cohort study evaluated patients who were diagnosed with high-risk stage II or III colorectal cancer and underwent elective surgery between 2010 and 2020. Five-year recurrence-free survival (RFS) was the primary endpoint and was compared between early SSI, delayed SSI (divided based on the median date of SSI onset), and non-SSI groups. RESULTS A total of 2,065 patients were included. Organ/space SSI was diagnosed in 91 patients (4.4%), with a median onset of 6 days after surgery. The early-onset SSI group had a higher proportion of patients with Clavien-Dindo grade ≥IIIb SSI than the delayed-onset SSI. Patients who received adjuvant chemotherapy (AC) had earlier organ/space SSI onset than those who did not. The adjusted hazard ratio of 5-year RFS in the delayed-onset SSI was 2.58 (95% confidence interval: 1.43-4.65; p = 0.002): higher than that in the early-onset SSI, with the non-SSI as the reference. CONCLUSIONS Delayed-onset organ/space SSI worsened long-term prognosis compared to early-onset, and this may be due to delayed initiation of AC. Patients who are clinically suspected of having lymph node metastasis might need additional intervention to prevent delays in commencing AC due to the delayed SSI.

Reconstruction, oversewing, or taking the anastomosis down - which surgical intervention is most potent in the treatment of anastomotic leaks following colorectal resections? Langenbecks Arch Surg 2023; 408:266. [PMID: 37405509 DOI: 10.1007/s00423-023-02986-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Accepted: 06/14/2023] [Indexed: 07/06/2023]
Abstract
PURPOSE Anastomotic leak (AL) following colorectal resections can be treated interventionally. However, most cases require surgical intervention. Thus, several surgical techniques are available, which intend to affect the further course positively. The aim of this retrospective analysis is to determine which surgical technique proves to have the biggest potential in reducing the morbidity and mortality as well as to minimize the need of re-interventions after AL. METHODS All patients with a history of AL following colorectal resection between 2008 and 2020 were analyzed. Patient's outcomes following surgical treatment of AL, including morbidity and mortality, clinical and para-clinical (laboratory examinations, ultrasound, and CT-scan) detection of AL recurrence, re-intervention rate, and the length of hospital stay were documented and correlated with the surgical technique used (e.g. simply over-sewing the AL, over-sewing the AL with the construction of a protective ileostomy, resection and reconstruction of the anastomosis, peritoneal lavage and transanal drainage, or taking the anastomosis down and constructing an end stoma). RESULTS A total of 2,724 colorectal resections were documented. Grade C AL occurred in 92 (4.4% AL occurrence-rate) and 31 (7.2% AL occurrence-rate) cases following colon and rectal resections, respectively. The anastomosis was not preservable in 52 and 17 cases following colon and rectal resections, respectively. Therefore, the anastomosis had been taken down and an end-stoma had been constructed. Over-sewing the AL with the construction of a protective ileostomy had the highest anastomosis preservation rate (14 of 18 cases) and lowest re-intervention rate (mean value of 1.5 re-interventions) following colon and rectal resections (7 of 9 cases; mean value, 1.5 re-interventions). CONCLUSION In cases where an AL is preservable, over-sewing the anastomosis and constructing a protective ileostomy has the greatest potential for positive short-term outcomes following colorectal resections.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies in the world. Despite significant improvements in surgical technique, postoperative complications still occur in a fair percentage of patients undergoing colorectal surgery. The most feared complication is anastomotic leakage. It negatively affects short-term prognosis, with increased post-operative morbidity and mortality, higher hospitalization time and costs. Moreover, it may require further surgery with the creation of a permanent or temporary stoma. While there is no doubt about the negative impact of anastomotic dehiscence on the short-term prognosis of patients operated on for CRC, still under discussion is its impact on the long-term prognosis. Some authors have described an association between leakage and reduced overall survival, disease-free survival, and increased recurrence, while other Authors have found no real impact of dehiscence on long term prognosis. The purpose of this paper is to review all the literature about the impact of anastomotic dehiscence on long-term prognosis after CRC surgery. The main risk factors of leakage and early detection markers are also summarized.

Abstract
BACKGROUND Indocyanine green, near infrared, fluorescence angiography (ICG-FA) is increasingly adopted in colorectal surgery for intraoperative tissue perfusion assessment to reduce anastomotic leakage rates. However, the economic impact of this intervention has not been investigated. This study is a cost analysis of the routine use of ICG-FA in colorectal surgery from the hospital payer perspective. METHODS A decision analysis model was developed for colorectal resections considering two scenarios: resection without using ICG-FA and resection with intraoperative ICG-FA for anastomotic perfusion assessment. Incorporated into the model were the costs of ICG agent, fluorescence angiography equipment, surgery, anastomotic leak, and the leak rates with and without ICG-FA. All input data were derived from recent publications. RESULTS The routine use of ICG-FA for colorectal anastomosis is cost saving when cost analysis is performed using the following base case assumptions: 8.6% leak rate without ICG-FA, odds ratio of 0.46 for reduction of leakage with ICG-FA (4.8% leak rate relative to 8.6% base case), cost of ICG-FA of $250, and incremental cost of leak, not requiring reoperation, of $9,934.50. In one-way sensitivity analyses, routine use of ICG-FA was cost saving if the cost of an anastomotic leak is more than $5616.29, the cost of ICG-FA is less than $634.44, the leak rate (without ICG-FA) is higher than 4.9%, or the odds ratio for reduction of leak with ICG-FA is less than 0.69. There is a per-case saving of $192.22 with the use of ICG-FA. CONCLUSION Using the best available evidence and most conservative base case values, routine use of ICG-FA in colorectal surgery was found to be cost saving. Since the evidence suggests there is a reduction in leak rate, the routine use of ICG-FA is a dominating strategy. However, the overall quality of evidence is low and there is a clear need for prospective, randomized controlled trials.

Anastomotic Leak Impact on Long-Term Survival after Right Colectomy for Cancer: A Propensity-Score-Matched Analysis. J Clin Med 2022; 11:jcm11154375. [PMID: 35955993 PMCID: PMC9369268 DOI: 10.3390/jcm11154375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Revised: 07/15/2022] [Accepted: 07/25/2022] [Indexed: 12/02/2022] Open
Abstract
Our goal was to assess the impact of anastomotic leaks (ALs) on oncologic outcomes using a case-matched analysis. Patients undergoing right hemicolectomy for cancer between 2014 and 2018 were included. The main variables were the risk factor of anastomotic leak, overall survival and disease-free survival. Propensity score matching was performed according to the patient’s age, co-morbidities and TNM staging as well as the type of procedure. Oncologic outcomes were analyzed. We included 488 patients and performed final analysis on 69 patients. The AL rate was 4.71% (23 patients). Intrahospital mortality was significantly higher in the AL group, at 1.3% (6 of 465) vs. 8.7% (2 of 23), p = 0.05. Three-year overall survival (OS) in the non-AL group was higher, although the difference could not be considered significant (71.5% vs. 37.3%, p = 0.082); similarly, the likelihood for impaired 3-year progression-free survival (PFS) was lower, but the difference here could also not be considered significant (69.3% vs. 37.3%, p = 0.106). Age, advanced tumor stage, lymph node metastases and distant metastases were associated with higher probability of death or recurrence of disease. In contrast, minimally invasive surgery was associated with lower probability of death (HR (95% CI): 0.99 (0.14–0.72); p = 0.023) and recurrence of disease (HR (95% CI): 0.94 (0.13–0.68); p = 0.020). In an adjusted Cox regression analysis, AL, age and distant metastases were associated with poor long-term survival. Moreover, AL, age and distant metastases were associated with higher probability of recurrence of disease. Based on our results, AL is a significant factor for worse oncologic outcomes. Simple summary: we aimed to assess patients with anastomotic leaks following right hemicolectomy for cancer. These patients were matched to patients without leaks. Propensity score analysis demonstrated that anastomotic leak was a marker of worse oncologic outcomes.

Abstract
Background We evaluated the influence of infectious complications, particularly surgical site infection (SSI), on long-term oncological results after elective laparoscopic resection of colorectal cancer. Methods A total of 199 patients who underwent laparoscopic elective resection with negative resection margins for stage I–III colorectal cancer were retrospectively examined. The postoperative course was recorded based on hospital records, and cancer relapse was diagnosed based on radiological or pathological findings under a standardized follow-up program. The severity of complications was graded using Clavien-Dindo (CD) classification. Results SSI was found in 25 patients (12.6%), with 12 (6.0%) showing anastomotic leak. The postoperative relapse-free survival (RFS) rate was significantly lower in patients with SSI (49.2%) than in patients without SSI (87.2%, P<0.001). Differences in RFS were found after both colectomy and rectal resection (P<0.001 and P<0.001, respectively). RFS did not differ between patients who had major SSI CD (grade III) and those who had minor SSI CD (grades I or II). Multivariate Cox regression analysis identified the occurrence of SSI and pathological stage as independent co-factors for RFS (P<0.001 and P=0.003). Conclusion These results suggest that postoperative SSI compromises long-term oncological results after laparoscopic colorectal resection. Further improvements in surgical technique and refinements in perioperative care may improve long-term oncological results.

Abstract
BACKGROUND In the present study, patients with colorectal anastomoses that were assessed with indocyanine green (ICG) fluorescence angiography (FA) were compared to patients who had only white light visual inspection of their anastomosis. The impact of change in surgical plan guided by ICG-FA on anastomotic leak (AL) rates was assessed. METHODS PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials were queried for eligible studies. Studies included were comparative cohort studies and randomized trials that compared perfusion assessment of colorectal anastomosis with ICG-FA and inspection under white light. Main outcome measures were change in surgical plan guided by ICG-FA and rates of AL. Risk of bias was assessed using RoB-2 and ROBINS-1 tools. Differences between the two groups in categorical and continuous variables were expressed as odds ratio (OR) with 95% confidence interval (CI) and weighted mean difference. RESULTS This systematic review included 27 studies comprising 8786 patients (48.5% males). Using ICG-FA was associated with significantly lower odds of AL (OR 0.452; 95% CI 0.366-0.558) and complications (OR 0.747; 95% CI 0.592-0.943) than the control group. The weighted mean rate of change in surgical plan based on ICG-FA was 9.6% (95% CI 7.3-11.8) and varied from 0.64% to 28.75%. A change in surgical plan was associated with significantly higher odds of AL (OR 2.73; 95% CI 1.54-4.82). LIMITATIONS Technical heterogeneity due to using different dosage of ICG and statistical heterogeneity in operative time and complication rates. CONCLUSION Assessment of colorectal anastomoses with ICG-FA is likely to be associated with lower odds of anastomotic leak than is traditional white light assessment. Change in plan based on ICG-FA may be associated with higher odds of AL. PROSPERO registration number: CRD42021235644.

Risk factors of symptomatic anastomotic leakage and its impacts on a long-term survival after laparoscopic low anterior resection for rectal cancer: a retrospective single-center study. World J Surg Oncol 2021; 19:187. [PMID: 34172053 PMCID: PMC8235623 DOI: 10.1186/s12957-021-02303-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 06/17/2021] [Indexed: 12/13/2022] Open
Abstract
Background Postoperative symptomatic anastomotic leakage (AL) is a serious complication after low anterior resection (LAR) for rectal cancer. AL can potentially affect short-term patient outcomes and long-term prognosis. This study aimed to explore the risk factors and long-term survival of symptomatic AL after laparoscopic LAR for rectal cancer. Methods From May 2009 to May 2015, 298 consecutive patients who underwent laparoscopic LAR for rectal cancer with or without a defunctioning stoma were included in this study. Univariate and multivariate logistic regression analyses were used to explore independent risk factors for symptomatic AL. Survival analysis was performed using Kaplan–Meier curves, and log-rank tests were used for group comparisons. Results Among the 298 patients enrolled in this study, symptomatic AL occurred in eight (2.7%) patients. The univariate analysis showed that age of ≤65 years (P = 0.048), neoadjuvant therapy (P = 0.095), distance from the anal verge (P = 0.078), duration of operation (P = 0.001), and pathological tumor (T) category (P = 0.004) were associated with symptomatic AL. The multivariate analysis demonstrated that prolonged duration of operation (P = 0.010) was an independent risk factor for symptomatic AL after laparoscopic LAR for rectal cancer. No statistically significant differences were observed in the 3-year (P = 0.785) and 5-year (P = 0.979) overall survival rates. Conclusions A prolonged duration of operation increased the risk of symptomatic AL after laparoscopic LAR for rectal cancer. An impact of symptomatic AL on a long-term survival was not observed in this study; however, further studies are required. Trial registration This study was registered in the Chinese Clinical Trial Registry (ChiCTR2000033413) on May 31, 2020.

Management and 1-year outcomes of anastomotic leakage after elective colorectal surgery. Int J Colorectal Dis 2021; 36:929-939. [PMID: 33118101 DOI: 10.1007/s00384-020-03777-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/08/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE To analyze different types of management and one-year outcomes of anastomotic leakage (AL) after elective colorectal resection. METHODS All patients with anastomotic leakage after elective colorectal surgery with anastomosis (76/1,546; 4.9%), with the exclusion of cases with proximal diverting stoma, were followed-up for at least one year. Primary endpoints were as follows: composite outcome of one-year mortality and/or unplanned intensive care unit (ICU) admission and additional morbidity rates. Secondary endpoints were as follows: length of stay (LOS), one-year persistent stoma rate, and rate of return to intended oncologic therapy (RIOT). RESULTS One-year mortality rate was 10.5% and unplanned ICU admission rate was 30.3%. Risk factors of the composite outcome included age (aOR = 1.08 per 1-year increase, p = 0.002) and anastomotic breakdown with end stoma at reoperation (aOR = 2.77, p = 0.007). Additional morbidity rate was 52.6%: risk factors included open versus laparoscopic reoperation (aOR = 4.38, p = 0.03) and ICU admission (aOR = 3.63, p = 0.05). Median (IQR) overall LOS was 20 days (14-26), higher in the subgroup of patients reoperated without stoma. At 1 year, a stoma persisted in 32.0% of patients, higher in the open (41.2%) versus laparoscopic (12.5%) reoperation group (p = 0.04). Only 4 out of 18 patients (22.2%) were able to RIOT. CONCLUSION Mortality and/or unplanned ICU admission rates after AL are influenced by increasing age and by anastomotic breakdown at reoperation; additional morbidity rates are influenced by unplanned ICU admission and by laparoscopic approach to reoperation, the latter also reducing permanent stoma and failure to RIOT rates.

Abstract
BACKGROUND Anastomotic leakage is still a feared complication after left-sided colonic resections. Various types of "anastomotic leak testing methods" are described in current literature. In this study we evaluated the use of intraoperative flexible endoscopy in comparison to conventional air leak testing after performing a circular stapled anastomosis in left-sided laparoscopic colon surgery. METHODS A retrospective database consisting of 130 patients with left sided colonic resections between 01/2015 and 12/2019 at our hospital was evaluated. After performing a circular stapled anastomosis flexible endoscopy was done in 69 cases, 61 patients were controlled with a conventional air leak test. Intraoperative and postoperative complications were recorded and retrospectively evaluated. RESULTS In the flexible endoscopy group, we observed complications in 13,04%, in the conventional air leak testing group in 9,83%. Postoperative anastomotic leakage was observed in 10,14% in the flexible endoscopy group and 4,91% in the conventional air leak test group. In 10,14% a positive air leak test was seen in the flexible endoscopy group and 11,47% in the conventional air leak testing group. In those cases, we observed no postoperative complications in the first group, in the conventional group we had two anastomotic leakages and one infected haematoma. CONCLUSIONS In the case of a positive air leak, flexible endoscopy offered a more exact detection of the leak. In those cases, no anastomotic leakage was observed postoperatively. In our opinion, flexible endoscopy should be recommended for testing the anastomosis intraoperatively in every left-sided colon surgery.

Abstract
We developed a new technique to reduce the length of the enteric defect to be closed during intracorporeal anastomosis in laparoscopic right hemicolectomy (LRH), also avoiding the need to suture the first part of the anastomosis in a deep space with an acute angle. From January 2017, after the ileo-colic anastomosis was completed, an additional stapler cartridge was applied starting at the colonic rim and including the small bowel part of the anastomosis. The isoperistaltic fashion of the ileo-colonic anastomosis was maintained. The remaining defect left to be closed was 2-3 cm. We compared the results of the novel technique with those of the 'standard' closure (full-length enterotomy). In the last 30 months, this technique was successfully used in 32 patients (Group A), compared with 33 patients (2012-2016) operated with 'standard' closure (Group B). Age, BMI and post-operative stage distribution were similar. The mean operative time was 175.2 min (± 36.7) in Group A and 165.9 min (± 42.5) in Group B (p = ns), with 53.1% and 27.3% of associated procedures (cholecystectomy, ovariectomy, etc.), respectively (p < 0.05). Overall morbidity rate was 28.1% and 30.3% (Group A vs Group B, p = ns), with no anastomotic bleeding/leak in either group. This technique, which simplifies the closure of the enteric defect after LRH with intracorporeal anastomosis is safe, reproducible and easy to learn. It might help more surgeons to perform a fully laparoscopic procedure in right hemicolectomy, offering the advantages of intracorporeal anastomosis to their patients.

Abstract
Background: To identify predictive factors for reoperation because of anastomotic leakage (AL) after colectomy. Methods: Between 2007 and 2016, all patients who developed AL following right or left colectomy in an expert center were included. Patients who were treated surgically (all including fecal diversion) were compared with those who were managed conservatively. Results: Overall, 81 (6.5%) patients developed AL, of which 32 (39%) were managed nonoperatively and 49 (61%) required reoperation. On average, AL was diagnosed on postoperative day 4 (3-8) and mortality reached 4.9% (n = 4). Reoperation included anastomosis resection in 31 (67%) patients of which 26 (100%) had right colectomy and 5 (25%) left colectomy. Reoperation for AL was associated with increased intensive care management (P = .026) and deep abdominal collection (P = .002). T stage >2 and right-sided colectomy were the only independent risk factors associated with the need for reoperation for AL. Stoma reversal was performed in 42 (98%) patients after a median of 4 months. Conclusions: AL after colectomy is more likely to require reoperation with fecal diversion after right-sided colectomy and T > 2 colorectal cancer.

Abstract
Background Anastomotic leakage (AL) significantly impairs short-term outcomes. The impact on the long-term outcomes remains unclear. This study aimed to identify the risk factors for AL and the impact on long-term survival in patients with left-sided colorectal cancer. Methods Nine-hundred patients with left-sided colorectal carcinoma who underwent sigmoid or rectal resection were enrolled in the study. Risk factors for AL after sigmoid or rectal resection were identified, and long-term outcomes of patients with and without AL were compared. Results AL rates following sigmoid and rectal resection were 5.1% and 10.7%, respectively. Higher ASA score (III–IV; OR = 10.54, p = 0.007) was associated with AL in patients undergoing sigmoid surgery on multivariable analysis. Male sex (OR = 2.40, p = 0.004), CCI score > 5 (OR = 1.72, p = 0.025), and T3/T4 stage tumors (OR = 2.25, p = 0.017) were risk factors for AL after rectal resection on multivariable analysis. AL impaired disease-free and overall survival in patients undergoing sigmoid (p = 0.009 and p = 0.001) and rectal (p = 0.003 and p = 0.014) surgery. Conclusion ASA score of III–IV is an independent risk factor for AL after sigmoid surgery, and male sex, higher CCI score, and advanced T stage are risk factors for AL after rectal surgery. AL impairs the long-term survival in patients undergoing left-sided colorectal surgery.

Abstract
BACKGROUND AND OBJECTIVE Anastomotic leakage is a serious complication after arterial resection of rectal cancer. It has been found that anastomotic leakage is related to the oncological outcome. The purpose of the study is to evaluate the long-term outcome of the rectal tumor after anastomotic leakage. METHODS The effect of anastomotic leakage on the oncological outcome of rectal cancer was studied by electronic literature retrieval. Using the DerSimonian Laird random effect model to calculate the odds ratio and 95% confidence interval. Research heterogeneity was evaluated by Q statistics and I2 , and bias was evaluated by funnel plot and Begg's test. RESULTS A total of 35 studies and 44 698 patients were included in the study. The studies have shown that anastomotic leakage is associated with local recurrence (OR = 1.93; 95% CI, 1.57-2.38; P < .0001), overall survival (OR = 1.64; 95% CI, 1.37-1.95; P < .00001), disease-free survival (OR = 2.07; 95% CI, 1.50-2.87; P < .00001) and cancer-specific survival (OR = 1.32; 95% CI, 1.02-1.70; P = .012), while it was not related to distant recurrence (OR = 1.25; 95% CI, 0.95-1.65; P = .12). CONCLUSIONS The results showed that anastomotic leakage after anterior resection increased the risk of local recurrence, decreased the overall survival, cancer-specific survival and disease-free survival.

Abstract
Anastomotic leak (AL) remains a potentially life-threatening sequela of colorectal surgery impacting on mortality, short- and long-term morbidity, quality of life, local recurrence (LR) and disease-free survival. Despite technical improvements and the identification of several surgery- and patient-related factors associated to the risk of AL, its incidence has not significantly changed over time. In this context, the clarification of the mechanisms underlying anastomotic healing remains an important unmet need, crucial for improving patients' outcomes. This review concentrates on novel key findings in the etiopathogenesis of AL, how they can contribute in determining LR, and measures which may contribute to reducing its incidence. AL results from a complex, dynamic interplay of several factors and biological processes, including host genetics, gut microbiome, inflammation and the immune system. Many of these factors seem to act in concert to drive both AL and LR, even if the exact mechanisms remain to be elucidated. The next generation sequencing technology, including the microbial metagenomics, could lead to tailored bowel preparations targeting only those pathogens that can cause AL. Significant progress is being made in each of the reviewed areas, moving toward translational and targeted therapeutic strategies to prevent the difficult complication of AL.

Abstract
Nowadays, the issue of splenic flexure mobilization (SFM) in anterior and low anterior rectal resection for rectal cancer is still debatable. This stage is important because dissection results tension-free anastomosis and excision of specimen of enough length with adequate number of harvested lymph nodes. However, literature review confirmed the absence of agreement regarding reduced incidence of colorectal anastomotic leakage and improved long-term oncologic outcomes after SFM. Opinion about selective approach to this procedure is becoming more common. Therefore, randomized trials are necessary to determine a need for routine SFM or indications for selective approach to SFM in anterior rectal resection for rectal cancer.

AIM Postoperative anastomotic leakage (AL) or bleeding (AB) significantly impacts on patient outcome following colorectal resection. To minimize such complications, surgeons can utilize different techniques perioperatively to assess anastomotic integrity. We aim to assess published anastomotic complication rates following left-sided colonic resection, comparing the use of intra-operative flexible endoscopy (FE) against conventional tests used to assess anastomotic integrity. METHODS PubMed/MEDLINE and Embase online databases were searched for non-randomized and randomized case-control studies that investigated postoperative AL and/or AB rates in left-sided colonic resections, comparing intra-operative FE against conventional tests. Data from eligible studies were pooled, and a meta-analysis using Review Manager 5.3 software was performed to assess for differences in AL and AB rates. RESULTS Data from six studies were analysed to assess the impact of FE on postoperative AL and AB rates (1084 and 751 patients respectively). Use of FE was associated with reduced postoperative AL and AB rates, from 6.9% to 3.5% and 5.8% to 2.4% respectively. Odds ratios favoured intra-operative FE: 0.37 (95% CI 0.21-0.68, P = 0.001) for AL and 0.35 (95% CI 0.15-0.82, P = 0.02) for AB. CONCLUSION This meta-analysis showed that the use of intra-operative FE is associated with a reduced rate of postoperative AL and AB, compared to conventional anastomotic testing methods.

Abstract
BACKGROUND/OBJECTIVE Anastomotic leakage (AL) is one of the most severe complications following colorectal cancer surgery and is associated with increased short and long term mortality. The literature is conflicting regarding increased risk of recurrence after AL. The aim of this study was to systematically review the impact of anastomotic leakage on the risk of local or distant recurrence and overall survival, cancer specific survival, and disease-free survival. METHODS A systematic review and meta-analysis was conducted in accordance with the PRISMA guidelines. A systematic search in PubMed, EMBASE, CINHAL, and The Cochrane Library was performed and meta-analyses were performed on all outcomes including analysis based on time-to-event data. RESULTS A total of eighteen cohort studies, including 69,047 patients whereof 2,555 patients had anastomotic leakage, were included. Meta-analysis demonstrated no significant effects of anastomotic leakage on local recurrence (RR 1.16, 95% CI 0.84-1.59) or distant recurrence (RR 1.44, 95% CI 0.52-3.96). Anastomotic leakage decreased overall survival (RR 0.85, 95% CI 0.77-0.94), disease free survival (RR 0.80, 95% CI 0.72-0.89), and cancer specific survival (RR 0.90, 95% CI 0.83-0.97). A time-to-event analysis was conducted on available data and the results were congruent with the frequency analyses. CONCLUSION Anastomotic leakage following colonic resections is significantly associated with impaired overall survival, disease free survival and cancer specific survival. The study did not show any statistically significant association between anastomotic leakage and recurrence.

Abstract
BACKGROUND Delayed initiation of adjuvant chemotherapy negatively impacts long-term survival in patients with colorectal cancer. Colorectal enhanced recovery protocols result in decreased complications and length of stay; however, the impact of enhanced recovery on the timing of adjuvant chemotherapy remains unknown. OBJECTIVE This study aimed to identify factors associated with on-time delivery of adjuvant chemotherapy after colorectal cancer surgery, hypothesizing that implementation of an enhanced recovery protocol would result in more patients receiving on-time chemotherapy. DESIGN This was a retrospective cohort study comparing the rate of on-time adjuvant chemotherapy delivery after colorectal cancer resection before and after implementation of an enhanced recovery protocol. SETTINGS The study was conducted at a large academic medical center. PATIENTS All of the patients who underwent nonemergent colorectal cancer resections for curative intent from January 2010 to June 2017, excluding patients who had no indication for adjuvant chemotherapy, had received preoperative systemic chemotherapy, or did not have medical oncology records available were included. MAIN OUTCOME MEASURES Patients before and enhanced recovery were compared, with the rate of on-time adjuvant chemotherapy delivery as the primary outcome. Adjuvant chemotherapy delivery was considered on time if initiated ≤8 weeks postoperatively, and treatment was considered delayed or omitted if initiated >8 weeks postoperatively (delayed) or never received (omitted). Multivariable logistic regression identified predictors of on-time chemotherapy delivery. RESULTS A total of 363 patients met inclusion criteria, with 189 patients (52.1%) undergoing surgery after enhanced recovery implementation. Groups differed in laparoscopic approach and median procedure duration, both of which were higher after enhanced recovery. Significantly more patients received on-time chemotherapy after enhanced recovery implementation (p = 0.007). Enhanced recovery was an independent predictor of on-time adjuvant chemotherapy (p = 0.014). LIMITATIONS The study was limited by its retrospective and nonrandomized before-and-after design. CONCLUSIONS Enhanced recovery was associated with receiving on-time adjuvant chemotherapy. As prompt initiation of adjuvant chemotherapy improves survival in colorectal cancer, future investigation of long-term oncologic outcomes is necessary to evaluate the potential impact of enhanced recovery on survival.

LA IMPLEMENTACIÓN DE UN PROTOCOLO DE RECUPERACIÓN ACELERADA SE ASOCIA CON EL INICIO A TIEMPO DE QUIMIOTERAPIA ADYUVANTE EN CÁNCER COLORRECTAL:: El inicio tardío de la quimioterapia adyuvante afecta negativamente la supervivencia a largo plazo en pacientes con cáncer colorrectal. Los protocolos de recuperación acelerada colorrectales dan lugar a una disminución de las complicaciones y la duración de estancia hospitalaria; sin embargo, el impacto de la recuperación acelerada en el momento de inicio de quimioterapia adyuvante sigue siendo desconocido.Este estudio tuvo como objetivo identificar los factores asociados con la administración a tiempo de la quimioterapia adyuvante después de la cirugía de cáncer colorrectal, con la hipótesis de que la implementación de un protocolo de recuperación acelerada daría lugar a que más pacientes reciban quimioterapia a tiempo.Estudio de cohorte retrospectivo que compara la tasa de administración de quimioterapia adyuvante a tiempo después de la resección del cáncer colorrectal antes y después de la implementación de un protocolo de recuperación acelerada.Centro médico académico grande.Todos los pacientes que se sometieron a resecciones de cáncer colorrectal no emergentes con intención curativa desde enero de 2010 hasta junio de 2017, excluyendo a los pacientes que no tenían indicación de quimioterapia adyuvante, que recibieron quimioterapia sistémica preoperatoria o no tenían registros médicos de oncología disponibles.Los pacientes se compararon antes y después de la implementación de la recuperación acelerada, con la tasa de administración de quimioterapia adyuvante a tiempo como el resultado primario. La administración de quimioterapia adyuvante se consideró a tiempo si se inició ≤8 semanas después de la operación, y el tratamiento se consideró retrasado / omitido si se inició> 8 semanas después de la operación (retrasado) o nunca fue recibido (omitido). La regresión logística multivariable identificó predictores de administración de quimioterapia a tiempo.363 pacientes cumplieron con los criterios de inclusión, con 189 (52.1%) pacientes sometidos a cirugía después de la implementación de recuperación acelerada. Los grupos difirieron en el abordaje laparoscópico y la duración media del procedimiento; ambos factores fueron mayores después de la recuperación acelerada. Significativamente más pacientes recibieron quimioterapia a tiempo después de la implementación de recuperación acelerada (p = 0.007). La recuperación acelerada fue un factor predictivo independiente de quimioterapia adyuvante a tiempo (p = 0.014).Diseño retrospectivo, tipo ¨antes y después¨ no aleatorizado.La recuperación acelerada se asoció con la recepción de quimioterapia adyuvante a tiempo. Debido a que el inicio rápido de la quimioterapia adyuvante mejora la supervivencia en el cáncer colorrectal, en el futuro será necesario investigar los resultados oncológicos a largo plazo para evaluar el impacto potencial de la recuperación acelerada en la supervivencia.

Abstract
PURPOSE Colorectal cancer is globally the third most common cancer. Anastomotic complications remain to be an important issue for colorectal surgery. The aim of this study was to investigate the protective effects of thymoquinone (TQ) on the healing process of left colonic anastomosis in an experimental model. METHODS Thirty-two male rats were divided into two groups, as the TQ group and the control group. TQ was administered to the TQ group, whereas the control group was given a standard feed and water for 2 wk. Following the creation of a left colonic anastomosis, subjects in both groups were sacrificed on the postoperative (PO) third and seventh days. Anastomotic burst pressures were measured mechanically. Immunohistochemical stainings for proliferating cell nuclear antigen, cluster of differentiation (CD) 31, CD45 were performed, and the matrix metalloproteinase-2 levels were measured. Histologic total scores were calculated according to Ehrlich-Hunt model. A value of P < 0.05 was considered as statistically significant. RESULTS One rat in the control group that died on the PO fourth day was excluded. Anastomotic burst pressures on the PO seventh day were higher in the TQ group than the control group (P < 0.01). Histopathological total scores on the PO third and seventh days were higher in the TQ group (P < 0.01). In addition, the TQ group revealed lower matrix metalloproteinase-2 scores on the PO third day and higher hydroxyproline levels on the PO seventh day (P < 0.05 and P < 0.01, respectively). CONCLUSIONS The use of TQ in colorectal surgery cases with left-sided colonic anastomosis resulted with increased anastomotic burst pressures and increased tissue hydroxyproline levels.

Abstract
The aim of this study was to investigate the influence of American Society of Anesthesiologists (ASA) scores on postoperative complication rates and total hospital charges following laparoscopic surgery for colorectal cancer.All patients (n = 664) underwent laparoscopic colorectal cancer surgery. A group of patients with an ASA score of 1 or 2 (n = 575) and a group of patients with an ASA score of 3 (n = 89) were compared.The mean age was higher in the group of patients with an ASA score of 3 than in the group of patients with an ASA score of 1 or 2 (70 vs 67 years). The rate of ICU admission (27% vs 15%) was higher in the ASA score 3 group. The mean hospital stay (14 vs 12 days) was longer in the ASA score 3 group. Postoperative 30-day complications (38% vs 27%), 30-day mortality (2% vs 0%), and a Clavien-Dindo classification of ≥3 (21% vs 11%) occurred more frequently in the ASA score 3 group. Mean total hospital charges were significantly higher in the ASA score 3 group (13,906 vs 11,575 USD). Independent risk factors that affected postoperative complications were older age [≥80 years, hazard ratio (HR) = 2.8], an ASA score of 3 (HR = 1.6), and the presence of a primary rectal tumor (HR = 1.6). Postoperative complication rates were 21.9%, 28.5%, and 38.2% in the ASA score 1, 2, and 3 groups, respectively. Total hospital charges were 14,376 USD and 10,877 USD in the groups with and without postoperative complications, respectively. Mean total hospital charges were 10,769 USD, 11,756 USD, and 13,906 USD in the ASA score 1, 2, and 3 groups, respectively.Preoperative ASA scores may be a predictor of postoperative complications and hospital costs when planning laparoscopic surgery for colorectal cancer.

Abstract
Recurrence following a resection for an adenocarcinoma of the gastroesophageal junction leads to reduced long-term survival. This study aims to identify risk factors associated with recurrence, recurrence localization, time to recurrence, and long-term survival. All patients undergoing curative intended resection for an adenocarcinoma of the gastroesophageal junction at Rigshospitalet between June 2003 and December 2011 were identified through a prospectively maintained nationwide database and enrolled in this study. Only histologically verified recurrence was considered eligible. Recurrence within six months, microscopically incomplete resection margins, and death within eight weeks were excluded. A total of 348 patients were included in this study. Biopsy-verified recurrence occurred in 120 patients (34.5%), with 32 local (9.2%), and 88 distant (25.3%) recurrences. Lymph node metastases was associated with an increased risk of recurrence (hazard ratio; [95% confidence interval]: HR = 2.7; [1.7-4.3], P < 0.001). Median time to local versus distant recurrence was 18 months (interquartile range (IQR): 9-37 months) versus 17 months (IQR: 11-27 months), P = 0.96, respectively. A trend toward local recurrence was identified if patients had anastomotic leakage (HR = 2.64; [0.89-7.86], P = 0.08). Survival was inversely associated with recurrence, but a survival comparison between local and distant recurrences showed no significant difference: median survival time was 28 months (IQR: 17-43 months) versus 24 months (IQR: 16-36 months), P = 0.45, respectively. A trend toward local recurrence was seen if the patient had an anastomotic leakage event. However, no factors were associated with site-specific recurrence (local vs. distant).

Abstract
Peritoneal infection after colorectal cancer surgery is associated with a higher rate of tumor relapse. We have recently proposed that soluble inflammatory factors released in response to a postoperative infection enhance tumor progression features in residual tumor cells. In an effort to set up models to study the mechanisms of residual tumor cell activation during surgery-associated inflammation, we have analyzed the phenotypic response of colon cancer cell lines to the paracrine effects of THP-1 and U937 differentiated human macrophages, which release an inflammatory medium characteristic of an innate immune response. The exposure of the colon cancer cell lines HT-29 and SW620 to conditioned media isolated from differentiated THP-1 and U937 macrophages induced a mesenchymal-like phenotypic shift, involving the activation of in vitro invasiveness. The inflammatory media activated the β-catenin/TCF4 transcriptional pathway and induced the expression of several mesenchymal (e.g., FN1 and VIM) and TCF4 target genes (e.g., MMP7, PTGS2, MET, and CCD1). Similarly, differential expression of some transcription factors involved in epithelial-to-mesenchymal transitions (i.e. ZEB1, SNAI1, and SNAI2) was variably observed in the colon cancer cell lines when exposed to the inflammatory media. THP-1 and U937 macrophages, which displayed characteristics of M1 differentiation, overexpressed some cytokines previously shown to be induced in colorectal cancer patients with increased rates of tumor recurrence associated with postoperative peritoneal infections, thus suggesting their pro-tumoral character. Therefore, the environment created by inflammatory M1 macrophages enhances features of epithelial-to-mesenchymal transition, and may be useful as a model to characterize pro-inflammatory cytokines as putative biomarkers of tumor recurrence risk.

Abstract
This study aimed to investigate the short-term outcomes of laparoscopic resection in comparison with those of open resection for colorectal cancer in patients with a history of prior median laparotomy (PML). Eighty-seven consecutive patients (87/1121, 7.8 %) with a history of PML who underwent major colorectal cancer resection were enrolled (laparoscopy, n = 40; open, n = 47). The conversion rate to open surgery was 25 % (n = 10). The laparoscopy group had a higher proportion of female patients (57.5 vs. 36.2 %), a lower rate of American Society of Anesthesiologists (ASA) score for physical status of ≥3 (7.5 vs. 25.5 %), and a lower pT4 tumor rate (15 vs. 38.3 %) than the open resection group. Regarding the reasons for PML, radical hysterectomy with extended lymphadenectomy for gynecologic cancer was more common (32.5 vs. 4.3 %), but gastrointestinal surgeries, such as gastrectomy and colectomy, were less frequent in the laparoscopy group. Regarding intraoperative outcomes, the laparoscopy group showed a similar operative time (197 vs. 204 min), intraoperative enterotomy rate (2.5 vs. 2.1 %), and bowel resection rate (2.5 vs. 2.1 %) with the open resection group. Regarding postoperative outcomes, the laparoscopy group showed a lower complication rate (20 vs. 40.4 %), significantly reduced time to soft diet (5 vs. 7 days), and shorter hospital stay (12 vs. 18 days). Despite the high rate of open conversion, favorable short-term outcomes were observed in the laparoscopic group. Laparoscopy may be chosen as the primary approach in selected patients with a history of non-gastrointestinal PML (prior abdominal surgery for gynecological cancer).

Abstract
AIM Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. METHOD Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. RESULTS Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. CONCLUSION Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

Abstract
AIM A large, prospectively collected, clinical database was analysed to determine the various pre- and intra-operative factors affecting anastomotic leakage (AL) in colorectal surgery. METHOD Data on 17 518 patients having a colorectal resection with anastomosis, taken from the 2013 American College of Surgeons National Surgical Quality Improvement Program database, were included in the study. Multivariable logistic regression analysis was carried out to identify risk-adjusted predictive factors for AL. Statistical significance was set at P < 0.05 and confidence intervals were reported at the 95% level. RESULTS The AL rate was 3.9% (687/17 518). Younger patients, male gender and an American Society of Anesthesiology (ASA) score of ≥ 3 (P < 0.001), smoking (P = 0.001), diabetes (P = 0.035), a preoperative serum albumin level of < 4 g/dl (P = 0.030), elective rectal cancer surgery (P = 0.024), emergency colectomy for bleeding (P = 0.013) and splenic flexure mobilization (P = 0.043) were associated with an increased risk of AL. Preoperative oral antibiotics (P < 0.001), right hemicolectomy (open or laparoscopic) and laparoscopic partial colectomy were associated with a reduced risk of AL compared with the entire group. Body mass index, preoperative chemotherapy, emergency surgery and mechanical bowel preparation were not related to AL. CONCLUSION In contrast to most studies, younger age was found to be an independent risk factor for AL. The risk for AL was lower with laparoscopic partial colectomy and open or laparoscopic right hemicolectomy. Preoperative oral antibiotic preparation significantly reduces the risk of AL and should be incorporated as a standard protocol.

Abstract
Purpose To identify the factors affecting 30-day postoperative complications and 1-year mortality after surgery for colorectal cancer in octogenarians and nonagenarians. Methods Between 2005 and 2014, a total of 204 consecutive patients aged ≥80 years who underwent major colorectal surgery were included. Results One hundred patients were male (49%) and 52 patients had American Society of Anesthesiologists (ASA) score ≥3 (25%). Combined surgery was performed in 32 patients (16%). Postoperative complications within 30 days after surgery occurred in 54 patients (26%) and 30-day mortality occurred in five patients (2%). Independent risk factors affecting 30-day postoperative complications were older age (≥90 years, hazard ratio [HR] with 95% confidence interval [CI] =4.95 [1.69−14.47], P=0.004), an ASA score ≥3 (HR with 95% CI =4.19 [1.8−9.74], P=0.001), performance of combined surgery (HR with 95% CI =3.1 [1.13−8.46], P=0.028), lower hemoglobin level (<10 g/dL, HR with 95% CI =7.56 [3.07−18.63], P<0.001), and lower albumin level (<3.4 g/dL, HR with 95% CI =3.72 [1.43−9.69], P=0.007). An ASA score ≥3 (HR with 95% CI =2.72 [1.15−6.46], P=0.023), tumor-node-metastasis (TNM) stage IV (HR with 95% CI =3.47 [1.44−8.39], P=0.006), and occurrence of postoperative complications (HR with 95% CI =4.42 [1.39−14.09], P=0.012) were significant prognostic factors for 1-year mortality. Conclusion Patient-related factors (older age, higher ASA score, presence of anemia, and lower serum albumin) and procedure-related factors (performance of combined surgical procedure) increased postoperative complications. Avoidance of 30-day postoperative complications may decrease 1-year mortality.

Abstract
PURPOSE To evaluate the pathologic, short-term and oncologic outcomes of laparoscopic and open complete mesocolic excision (CME) and central ligation for right-sided colon cancer. METHODS All patients (n = 215) underwent elective CME either by open surgery (n = 99) or laparoscopy (n = 116). RESULTS Mean number of retrieved lymph nodes (31 vs. 27, p = 0.012) was greater in the open CME group. Between the open and laparoscopic CME groups, there were no differences of length of the specimen (44.3 cm and 43.2 cm), ileum (14 cm and 13.3 cm), or colon (30.3 cm and 29.8 cm), respectively. Proximal and distal margins were similar. Mean operative time was similar between the open and laparoscopic CME groups (175 min vs. 178 min). The rate of 30-day postoperative complications (36.4% vs. 23.3%, p = 0.036) was higher in the open CME group. There were no differences in 3-year overall survival rates (86.9% vs. 95.5% in stage II disease and 70.2% vs. 90.7% in stage III disease) or recurrence-free survival rates (84.5% vs. 84.8% in stage II disease and 64.2% vs. 68.9% in stage III disease) between the open and laparoscopic CME groups. CONCLUSIONS Pathologic (specimen lengths, resection margin lengths, number of lymph nodes, and R0 resection) and oncologic outcomes of the laparoscopic CME group were comparable. Moreover, laparoscopic CME conferred short-term benefits in terms of lower rates of postoperative complications, reduced time to soft diet, and reduced length of hospital stay. Based on these results, laparoscopic CME can be considered as a routine elective approach for right-sided colon cancer.

Abstract
OBJECTIVE Robot-assisted surgery has been reported to be a safe and effective alternative to conventional laparoscopy for the treatment of rectal cancer in a minimally invasive manner. Nevertheless, substantial data concerning functional outcomes and long-term oncological adequacy is still lacking. We aimed to assess the current role of robotics in rectal surgery focusing on patients' functional and oncological outcomes. METHODS A comprehensive review was conducted to search articles published in English up to 11 September 2015 concerning functional and/or oncological outcomes of patients who received robot-assisted rectal surgery. All relevant papers were evaluated on functional implications such as postoperative sexual and urinary dysfunction and oncological outcomes. RESULTS Robotics showed a general trend towards lower rates of sexual and urinary postoperative dysfunction and earlier recovery compared with laparoscopy. The rates of 3-year local recurrence, disease-free survival and overall survival of robotic-assisted rectal surgery compared favourably with those of laparoscopy. CONCLUSIONS This study fails to provide solid evidence to draw definitive conclusions on whether robotic systems could be useful in ameliorating the outcomes of minimally invasive surgery for rectal cancer. However, the available data suggest potential advantages over conventional laparoscopy with reference to functional outcomes.
