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 To investigate the relationship between prognostic nutritional index (PNI) and the survival of patients with colorectal cancer (CRC) undergoing surgical treatment. Methods In total 1,014 CRC patients who underwent surgical treatment were enrolled. Logistic regression analysis was used to identify the features that influenced postoperative complications in CRC patients. Restricted cubic spline was used to assess the dose-response relationship between PNI and survival in CRC patients. Kaplan-Meier method and log-rank test were used to compare survival differences between groups of CRC patients. Cox proportional risk regression models was used to assess independent risk factors for progression-free survival (PFS) and overall survival (OS) of CRC patients. Results Low PNI was associated with high tumor burden, invasive pathological features, and poor host status. Compared with patients with high PNI, patients with low PNI have a higher incidence of complications and longer hospital stay. Low PNI was an independent risk factor for postoperative complications in CRC patients. for every SD increased in PNI, the risk of poor prognosis for CRC patients was reduced by 2.3% (HR = 0.977, 95%CI = 0.962-0.993, p = 0.004) in PFS, and 2.3% (HR = 0.977, 95%CI = 0.962-0.993, p = 0.004) in OS. PNI was an independent prognostic factor affecting the PFS and OS of CRC patients. Finally, we constructed the PNI-based nomograms to predict postoperative complications, 1-5 years PFS and OS in CRC patients. Concordance index and calibration curve indicated that the PNI-based nomograms have moderate prediction accuracy. Conclusion PNI is an independent risk factor affecting postoperative complications, PFS and OS of CRC patients, and is a useful supplement to the TNM stage.

Abstract
BACKGROUND Anastomotic leaks (AL) remain a devastating complication following intestinal anastomoses resulting in increased morbidity and mortality. Wrapping the anastomosis with omentum may be protective although data are conflicting. We performed a meta-analysis to assess the effect of omentoplasty on colorectal anastomoses. METHODS PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until August 2021. All randomized controlled trials (RCT) that reported on the use of omentoplasty in colon and rectal surgery were included. The primary outcome was rate of overall AL while secondary outcomes included clinical and radiological AL, overall reoperation and mortality. Random effects models were used to calculate pooled effect size estimates. Sensitivity analyses were also performed. RESULTS Four RCTs were included capturing 1067 patients. The mean (SD) age of the cohort was 61.5 (±14.8) years. On random effects analysis, omentoplasty reduced rate of overall (OR 0.43, 95% CI = 0.21-0.87, p = 0.02) and clinical AL (OR = 0.35, 95% CI = 0.15-0.81, p = 0.01). However, there was no difference in radiological AL (OR = 0.77, 95% CI = 0.40-1.47, p = 0.42), overall reoperations (OR 0.48, 95% CI = 0.18-1.32, p = 0.16) or mortality (OR 0.52, 95% CI = 0.12 to-2.18, p = 0.37). On sensitivity analysis, assessing rectal anastomoses only, the results for overall AL remained similar (OR 0.28, 95% CI = 0.12-0.61, p = 0.002). CONCLUSION Although omentoplasty appears to reduce the rate of overall and clinical AL, the heterogeneity in the data prevents definitive recommendations from being made. Further well-designed trials are needed to investigate this technique.

Abstract
OBJECTIVE The aim of this study was to evaluate oncological outcome for patients with and without anastomotic leakage after colon or rectal cancer surgery. SUMMARY OF BACKGROUND DATA The role of anastomotic leakage in oncological outcome after colorectal cancer surgery is still topic of debate and impact on follow-up and consideration for further treatment remains unclear. METHODS Patients included in the international, multicenter, non-inferior, open label, randomized, controlled trials COLOR and COLOR II, comparing laparoscopic surgery for curable colon (COLOR) and rectal (COLOR II) cancer with open surgery, were analyzed. Patients operated by abdominoperineal excision were excluded. Both univariate and multivariate analyses were performed to investigate the impact of leakage on overall survival, disease-free survival, local and distant recurrences, adjusted for possible confounders. Primary endpoints in the COLOR and COLOR II trial were disease-free survival and local recurrence at 3-year follow-up, respectively, and secondary endpoints included anastomotic leakage rate. RESULTS For colon cancer, anastomotic leakage was not associated with increased percentage of local recurrence or decreased disease-free-survival. For rectal cancer, an increase of local recurrences (13.3% vs 4.6%; hazard ratio 2.96; 95% confidence interval 1.38-6.34; P = 0.005) and a decrease of disease-free survival (53.6% vs 70.9%; hazard ratio 1.67; 95% confidence interval 1.16-2.41; P = 0.006) at 5-year follow-up were found in patients with anastomotic leakage. CONCLUSION Short-term morbidity, mortality, and long-term oncological outcomes are negatively influenced by the occurrence of anastomotic leakage after rectal cancer surgery. For colon cancer, no significant effect was observed; however, due to low power, no conclusions on the influence of anastomotic leakage on outcomes after colon surgery could be reached. Clinical awareness of increased risk of local recurrence after anastomotic leakage throughout the follow-up is mandatory.Trial Registration: Registered with ClinicalTrials.gov, number NCT00387842 and NCT00297791.

Abstract
At inception, transanal total mesorectal excision (TaTME) was hypothesized to be a solution for several problems encountered in pelvic surgery, particularly for distal rectal cancer. The transanal part of the procedure is less hampered by patient related factors such as visceral obesity and a narrow bony pelvis and can thus overcome access and visualization problems encountered with a pure abdominal approach. Clearly, as for any new technique, a learning curve needs to be negotiated, ideally without unacceptable harm to patients. Once in experienced hands, TaTME might overcome challenges found in anatomically challenging rectal cancer patients as well as for other indications. The role of TaTME is not to replace, but rather complement its abdominal counterpart.

Abstract
BACKGROUND Anastomotic leakage (AL) is a major complication of colorectal surgery resulting in morbidity, mortality and poorer quality of life. The early diagnosis of AL is challenging due to the poor positive predictive value of tests available and reliance on clinical presentation which may be delayed. The aim of this systematic review was to assess the applicability of peritoneal cytokine levels as an early predictive test of AL in postoperative colorectal cancer patients. METHODS A comprehensive literature search was performed from inception to January 2021, in MEDLINE and EMBASE databases using MeSH and non-MeSH terms in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All studies evaluating peritoneal cytokines in the context of AL were included in this review. RESULTS Two hundred ninety-two abstracts were screened, 30 full manuscripts evaluated, and 12 prospective studies were included. There were 8 peritoneal cytokines evaluated (interleukin [IL]-1β, IL-6, IL-8, IL-10, vascular endothelial growth factor [VEGF], tumour necrosis factor alpha [TNF alpha] and matrix metalloproteinase [MMP]2 and MMP9) between AL and non-AL groups on postoperative day 1. Those that included IL-6 (7 studies), IL-10 (4 studies), TNF alpha (6 studies) and MMP9 (2 studies) were included in the meta-analysis. IL-10 was the only cytokine in the meta-analysis that was significantly (p < 0.05) raised in drain fluid on postoperative day 1 in AL patients. CONCLUSIONS Peritoneal IL-10 was significantly raised on postoperative day 1 in patients who subsequently developed AL. This may be a useful early predictor of AL and aid in an earlier diagnosis for postoperative colorectal patients. The range of cytokines investigated within the literature is limited and from heterogeneous studies which suggests more research is needed.

Abstract
Introduction: Transanal total mesorectal excision (TaTME) is a novel technique that overcomes the problem of access to the deep pelvis during radical surgery for mid-rectal and lower rectal cancer. Although TaTME has several important steps, the creation of the distal purse-string suture following TaTME plays an important role in ensuring the integrity of the colorectal anastomosis. However, this procedure represents a major technical challenge for the surgeon. Robot-assisted surgery may make this suturing procedure easier than laparoscopic surgery because it permits intuitive wrist movements and a three-dimensional view. The aim of the present study was to investigate the usefulness of transabdominal robotic purse-string suture during anastomosis in TaTME. Methods: Twenty-seven patients, who underwent anastomosis using a single stapling technique (SST) during the TaTME of mid-rectal or lower rectal cancer, were enrolled in the study. The patients were allocated to two groups: 11 patients underwent transabdominal robotic purse-string suturing (the Robot group) and 16 patients underwent transanal purse-string suturing (the Transanal group). The characteristics and short-term surgical outcomes of the participants were compared between the two groups. Results: The Robot group tended to have a shorter purse-string suturing time (541 ± 206 seconds versus 729 ± 310 seconds; P = .07). Regarding the shape of the "donut" after SST anastomosis, in the Transanal group, 5 of the 16 participants had incomplete donuts with muscular defects and required additional suturing, whereas in the Robot group, all the participants had complete donuts (P = .04). Conclusions: Transabdominal robotic purse-string suturing may facilitate the suturing procedure and contribute to reliable anastomosis.

Abstract
BACKGROUND Anastomotic leakage might be directly or indirectly related to the prognosis of patients with rectal cancer. OBJECTIVE This study aimed to investigate whether anastomotic leakage affects the oncologic outcomes in patients with rectal cancer. DESIGN This was a retrospective analysis of prospectively collected data. SETTINGS This study was conducted at a teaching hospital between January 2009 and December 2013. PATIENTS Patients who underwent curative resection for primary rectal cancer were included. MAIN OUTCOME AND MEASURE Kaplan-Meier analyses were used to evaluate disease-free survival and overall survival. RESULTS The overall incidence of anastomotic leakage was 2.7% (107/3865). Local recurrence was more frequent in patients with anastomotic leakage than in those without (14.0% vs 6.7%; p = 0.007). By multivariate analysis, anastomotic leakage was associated with increased local recurrence rate (p = 0.014) and poorer overall survival (p = 0.011). In subgroup analysis, compared with other pathologic risk factors, anastomotic leakage was associated with higher occurrence of local and distant recurrence in patients with stage II rectal cancer (p = 0.031 and <0.001). In patients with stage III rectal cancers, adjuvant therapy was more likely to be delayed or canceled in those experiencing anastomotic leakage (63 vs 39 d, p < 0.001; 37.3% vs 66.7%, p < 0.001). In addition, this patient group had the worst survival outcome when compared with those without anastomotic leakage and those with timely adjuvant therapy (5-year disease-free survival rate, p = 0.013; 5-year overall survival rate, p = 0.001). LIMITATIONS This study is limited by its retrospective nature. CONCLUSIONS There was a robust association between anastomotic leakage and local recurrence, while also potentially affect long-term survival of the patient group. Delayed or cancelled adjuvant therapy administration because of anastomotic leakage may partly account for the poorer survival in those patients with advanced rectal cancer.

EFECTOS DE OBSERVANCIA DE TERAPIA ADYUVANTE Y FUGA ANASTOMTICA, EN RESULTADOS ONCOLGICOS DE PACIENTES CON CNCER RECTAL, DESPUS DE UNA RESECCIN CURATIVA ANTECEDENTES:La fuga anastomótica podría estar relacionada directa o indirectamente, con el pronóstico de los pacientes con cáncer de recto.OBJETIVO:El estudio tuvo como objetivo investigar si la fuga anastomótica afecta los resultados oncológicos, en pacientes con cáncer de recto.DISEÑO:Fue un análisis retrospectivo de datos recolectados prospectivamente.AJUSTE:El estudio se realizó en un hospital universitario entre enero de 2009 y diciembre de 2013.PACIENTES:Pacientes sometidos a resección curativa por cáncer rectal primario.PRINCIPALES MEDIDAS DE RESULTADO:Se utilizaron análisis de Kaplan-Meier para evaluar la supervivencia libre de enfermedad y supervivencia general.RESULTADOS:La incidencia global de fuga anastomótica fue del 2,7% (107/3865). La recurrencia local fue más frecuente en pacientes con fuga anastomótica, que en aquellos sin ella (14,0% frente a 6,7%, p = 0,007). Por análisis multivariado, la fuga anastomótica se asoció con una mayor tasa de recurrencia local (p = 0,014) y una peor supervivencia general (p = 0,011). En el análisis de subgrupos, en comparación con otros factores de riesgo patológicos, la fuga anastomótica se asoció con una mayor incidencia de recidiva local y a distancia en pacientes con cáncer rectal en estadio II (p = 0,031 y <0,001, respectivamente). En pacientes con cáncer rectal estadio III, la terapia adyuvante tuvo más probabilidades de retrasarse o cancelarse en aquellos que sufrían fuga anastomótica (63 vs 39 días, p <0,001; 37,3% vs 66,7%, p <0,001). Y este grupo de pacientes tuvo el peor resultado de supervivencia en comparación con aquellos sin fuga anastomótica y aquellos con terapia adyuvante oportuna (tasa de supervivencia libre de enfermedad a 5 años, p = 0,013; tasa de supervivencia global a 5 años, p = 0,001).LIMITACIONES:El estudio está limitado por su naturaleza retrospectiva.CONCLUSIONES:Hubo una sólida asociación entre la fuga anastomótica y la recurrencia local, mientras que también afecta potencialmente la supervivencia a largo plazo, del grupo de pacientes. La administración de terapia adyuvante retrasada o cancelada debido a una fuga anastomótica, puede explicar en parte, la menor supervivencia en aquellos pacientes con cáncer rectal avanzado.

Risk Factors for Anastomotic Leakage after Colorectal Surgery with Double-staple Technique Anastomosis: Impact of the Agatston Score. JOURNAL OF THE ANUS RECTUM AND COLON 2021; 5:181-187. [PMID: 33937559 PMCID: PMC8084537 DOI: 10.23922/jarc.2020-099] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 02/03/2021] [Indexed: 01/23/2023]
Abstract
Objectives Anastomotic leakage is associated with severe morbidity, mortality, and functional defects. Its risk factors remain unclear. However, blood perfusion may be a potential major risk factor. It has been reported that the Agatston score is an index for blood flow perfusion evaluation. Therefore, we evaluated the clinical indicators associated with anastomotic leakage, including the Agatston score, in patients who underwent colorectal surgery. Methods We retrospectively analyzed 147 patients who underwent elective colorectal surgery with the double-staple technique anastomosis for colorectal cancer between April 2015 and March 2020. The primary outcome was the presence or absence of anastomotic leakage. Univariate and multivariate analyses were employed to identify pre- and intraoperative risk factors. Results Of the 147 patients analyzed, anastomotic leakage occurred in 12 (8.16%). Male gender, history of angina and myocardial infarction, preoperative white blood cell count, the Agatston score, extent of bleeding, operation time, and intraoperative fluid volume were significantly related to a higher incidence of anastomotic leakage in univariate analysis. Multivariate analysis demonstrated that the incidence of anastomotic leakage was high in patients with a high Agatston score. Conclusions The Agatston score can predict the incidence of anastomotic leakage in patients following colorectal surgery. Thus, perioperative measures to prevent anastomotic leakage are recommended when a high Agatston score is observed. A prospective trial is required to demonstrate, with a high level of evidence, that the Agatston score can be useful as a risk score for anastomotic leakage following colorectal surgery.

Abstract
BACKGROUND Cancer outcomes are complex, involving prevention, early detection and optimal multidisciplinary care. Postoperative infection and surgical site-infection (SSI) are not only uncomfortable for patients and costly, but may also be associated with poor oncological outcomes. A meta-analysis was undertaken to assess the oncological effects of SSI in patients with colorectal cancer. METHODS An ethically approved PROSPERO-registered meta-analysis was conducted following PRISMA guidelines. PubMed and Scopus databases were searched for studies published between 2007 and 2017 reporting the effects of postoperative infective complications on oncological survival in colorectal cancer. Results were separated into those for SSI and those concerning anastomotic leakage. Articles with a Methodological Index for Non-Randomized Studies score of at least 18 were included. Hazard ratios (HRs) with 95 per cent confidence intervals were computed for risk factors using an observed to expected and variance fixed-effect model. RESULTS Of 5027 articles were reviewed, 43 met the inclusion criteria, with a total of 154 981 patients. Infective complications had significant negative effects on overall survival (HR 1·37, 95 per cent c.i. 1·28 to 1·46) and cancer-specific survival (HR 2·58, 2·15 to 3·10). Anastomotic leakage occurred in 7·4 per cent and had a significant negative impact on disease-free survival (HR 1·14, 1·09 to 1·20), overall survival (HR 1·34, 1·28 to 1·39), cancer-specific survival (HR 1·43, 1·31 to 1·55), local recurrence (HR 1·18, 1·06 to 1·32) and overall recurrence (HR 1·46, 1·27 to 1·68). CONCLUSION This meta-analysis identified a significant negative impact of postoperative infective complications on overall and cancer-specific survival in patients undergoing colorectal surgery.

Abstract
BACKGROUND Anastomotic leak remains a critical complication after restorative rectal cancer surgery and is associated with significant morbidity and mortality rates, whereas reported rates range from 4% to 29%. Whether the occurrence of leak may have an impact on long-term oncological outcomes is under debate. OBJECTIVE This study aimed to describe the oncological impact of anastomotic leak on patients undergoing sphincter-preserving surgery for rectal adenocarcinoma. DESIGN This is a retrospective review of a prospectively maintained database. SETTINGS The study was conducted at a high-volume colorectal center. PATIENTS Data on patients who underwent restorative surgery for rectal adenocarcinoma from January 2000 until December 2013 were retrospectively analyzed. MAIN OUTCOME MEASURES The primary outcome measured was the impact of anastomotic leak, defined according to the classification proposed by the International Study Group of Rectal Cancer, on long-term overall survival, disease-free survival, disease-specific survival, and local recurrence. RESULTS A total of 787 patients undergoing sphincter-preserving surgery for rectal cancer met the inclusion criteria. Forty-two (5.3%) patients presented a symptomatic anastomotic leak. The median follow-up period was 64 months. Fifty-one (6.5%) patients experienced a cancer-related death, 2 of 42 in the anastomotic leak group. Five-year overall survival, disease-specific survival, and disease-free survival were 88%, 94.7%, and 85.3%. Local recurrence rate was 2%. There was no difference in long-term overall survival, disease-specific survival, disease-free survival, and local recurrence rate between groups. On a multivariable analysis, anastomotic leak did not impact oncological outcomes. LIMITATIONS This study was limited by retrospective analysis. CONCLUSIONS The occurrence of anastomotic leak after restorative resection for rectal cancer did not impact long-term oncological outcomes in our cohort of patients.

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
OBJECTIVE To determine the incidence of anastomotic-related morbidity following Transanal Total Mesorectal Excision (TaTME) and identify independent risk factors for failure. BACKGROUND Anastomotic leak and its sequelae are dreaded complications following gastrointestinal surgery. TaTME is a recent technique for rectal resection, which includes novel anastomotic techniques. METHODS Prospective study of consecutive reconstructed TaTME cases recorded over 30 months in 107 surgical centers across 29 countries. Primary endpoint was "anastomotic failure," defined as a composite endpoint of early or delayed leak, pelvic abscess, anastomotic fistula, chronic sinus, or anastomotic stricture. Multivariate regression analysis performed identifying independent risk factors of anastomotic failure and an observed risk score developed. RESULTS One thousand five hundred ninety-four cases with anastomotic reconstruction were analyzed; 96.6% performed for cancer. Median anastomotic height from anal verge was 3.0 ± 2.0 cm with stapled techniques accounting for 66.0%. The overall anastomotic failure rate was 15.7%. This included early (7.8%) and delayed leak (2.0%), pelvic abscess (4.7%), anastomotic fistula (0.8%), chronic sinus (0.9%), and anastomotic stricture in 3.6% of cases. Independent risk factors of anastomotic failure were: male sex, obesity, smoking, diabetes mellitus, tumors >25 mm, excessive intraoperative blood loss, manual anastomosis, and prolonged perineal operative time. A scoring system for preoperative risk factors was associated with observed rates of anastomotic failure between 6.3% to 50% based on the cumulative score. CONCLUSIONS Large tumors in obese, diabetic male patients who smoke have the highest risk of anastomotic failure. Acknowledging such risk factors can guide appropriate consent and clinical decision-making that may reduce anastomotic-related morbidity.

Abstract
BACKGROUND The impact of postoperative complications (POCs) on the long-term prognosis of patients with colorectal carcinoma was analysed with respect to their severity according to the Clavien-Dindo classification (CDC). METHODS The prospectively collected data of 2158 patients who underwent curative resection of a colorectal carcinoma (1168 rectal carcinomas, 990 colon carcinomas) without distant metastases from 1995 to 2014 were analysed. The POCs were documented in a standardized form and graded with the CDC. Patients who died postoperatively (CDC grade V, 1.7%) were excluded. RESULTS In total, 467 patients (21.6%) had POCs: CDC I, 141 (6.5%); CDC II, 162 (7.5%); CDC III, 112 (5.2%); and CDC IV, 52 (2.4%). More POCs and higher CDC grades were found in men, ASA III-IV patients, rectal carcinoma patients, and patients who underwent abdominoperineal excisions or multivisceral resections. The 5-year locoregional recurrence rate was 5.3% in patients without POCs and 6.6% in patients with POCs. It was highest in CDC III patients (12.9%), which was confirmed in multivariate analysis (HR 2.2; p = 0.005). The 5-year distant metastasis rate was 15.9% in CDC 0 patients and 19.5% in CDC I-IV patients. In multivariate analysis, distant metastasis was highest in CDC III patients (HR 1.7; p = 0.020). The 5-year overall survival rate was 83.5% in patients without POCs and 73.5% in patients with POCs. It was worst in CDC IV patients (63.1%), which was confirmed by multivariate analysis (HR 1.9; p = 0.001). CONCLUSION Patients with POCs after colorectal surgery have a poor long-term prognosis. As the CDC grade increases, survival deteriorates.

Abstract
AIM The transanal approach to total mesorectal excision (TaTME) as an alternative to conventional anterior resection offers an improved view to otherwise restricted anatomical regions in obese and narrow male pelves and unfavourable tumour locations. Guidelines for the management of anastomotic leakage (AL) following low rectal resections are scarce. PATIENTS AND METHODS Prospectively collected data of all consecutive patients undergoing TaTME between December 2014 and April 2017 in our centre were analysed retrospectively. Existing classification systems for AL were modified with regard to transanal anastomotic-preserving management. RESULTS TaTME was performed in 66 patients with a median age of 56.2 years. The overall incidence of AL was 12.1% (n = 8). AL grading was differentiated in Grades I to V according to the severity of necrosis and abscess development. Two patients suffered from AL Grade II, one patient from Grade III, three patients from Grade IV and two patients from Grade V. Preservation of the anastomosis following AL was achieved by the damage control concept in six of eight patients (75%) with a median duration of hospital stay of 36 days. Two patients received a Hartmann procedure (Grades IV and V). CONCLUSION Our study demonstrates that management of AL following TaTME is challenging but definitely amenable to strategies aimed at preserving the anastomosis by appropriate damage control. The modified classification system might serve as guidance for anastomosis-preserving management.

Abstract
Background Anastomotic leakage (AL) is a common complication after anterior resection of rectal cancer. Few studies have been conducted to determine whether the traditional predictors of AL can be applied to elderly patients (age ≥ 80) undergoing anterior resection (AR) or low anterior resection (LAR) of rectal cancer. This study was designed to explore the predictive factors for AL after anterior resection of rectal cancer in patients over 80 years old. Methods From January 2007 to May 2019, consecutive elderly (age ≥ 80) rectal cancer patients undergoing AR or LAR at our institution were systematically reviewed. The general information, perioperative outcomes, and comorbidities were collected. Results A total of 288 consecutive patients were included in this study. The average age was 82.8 ± 2.4 years, and 30 (10.4%) patients developed AL. The univariate analyses showed that neoadjuvant therapy (50.0% vs. 27.9%, P = 0.013), the number of stapler firings ≥ 3 (60.0% vs. 36.0%, P = 0.011), and coronary heart disease (CHD) (46.7% vs. 17.8%, P < 0.001) were associated with an increased incidence of AL. The multivariate analysis showed that the number of stapler firings ≥ 3 (OR = 4.77, 95% CI = 1.33–15.21, P = 0.035) and CHD (OR = 8.33, 95% CI = 1.94–13.05, P = 0.003) were independent risk factors for AL. Conclusion The number of stapler firings ≥ 3 and CHD were independent risk factors for AL in elderly patients (age ≥ 80) with rectal cancer. A temporary ileostomy or the Hartmann procedure is recommended for patients with CHD, male patients, patients considered to be obese, and patients with a lower tumor location, which may increase the number of stapler firings. Certainly, we recommend that the number of stapler firings should be minimized to alleviate the economic and physical burden of patients.

Influence of Anastomotic Leak After Elective Colorectal Cancer Resection on Survival and Local Recurrence: A Propensity Score Analysis. Dis Colon Rectum 2019; 62:286-293. [PMID: 30540662 DOI: 10.1097/dcr.0000000000001287] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/25/2022]
Abstract
BACKGROUND The occurrence of anastomotic leakage is still a life-threatening complication for patients after colorectal surgery. In literature not only an impact on the short-term outcome but also on long-term survival and local recurrence of colorectal cancer patients is discussed. OBJECTIVE This study aimed to investigate the impact of anastomotic leakage on long-term survival and local recurrence. DESIGN A total of 1122 patients with resections for colorectal cancer were analyzed. In 94 patients (8.4%) there was clinical proof of anastomotic leakage. A reference group was defined as the 1028 patients without anastomotic leakage using 1:1 propensity score-matching according to the following criteria: age, sex, International Union Against Cancer stage, Karnofsky index, tumor site, and grading, as well as adjuvant chemotherapy. A calculation of overall survival, disease-free survival, and local recurrence rate was performed for both groups. SETTINGS The study was conducted using a retrospective matched-pairs analysis, based on a prospectively maintained institutional colorectal cancer database. PATIENTS Ninety-four patients with anastomotic leakage and 94 matched control subjects from a total of 1122 patients with resections for colorectal cancer were studied. MAIN OUTCOME MEASURES Overall survival, disease-free survival, and local recurrence rate for patients with colorectal cancer with and without anastomotic leakage were measured. RESULTS The propensity score matching successfully created 2 groups with no significant differences in the matching criteria. Survival analysis disclosed no significant differences between the groups in terms of overall survival, disease-free survival, and local recurrence rate. Univariate analysis identified age, Karnofsky index, International Union Against Cancer stage, and lymph node metastasis as significant prognostic factors. Multivariable analysis of these variates revealed age and positive lymph nodes as independent predictors of overall survival and disease-free survival. LIMITATIONS The study was limited by nature of being a retrospective analysis and monocentric study. CONCLUSIONS This matched-pairs analysis, comparing patients with colorectal cancer with and without anastomotic leakage, revealed no significant differences in overall survival, disease-free survival, and local recurrence rate. Contrary results in the literature might be caused by nonbalanced settings in nonmatched collectives. See Video Abstract at http://links.lww.com/DCR/A811.

Routine preoperative mechanical bowel preparation with additive oral antibiotics is associated with a reduced risk of anastomotic leakage in patients undergoing elective oncologic resection for colorectal cancer. World J Surg Oncol 2019; 17:20. [PMID: 30651119 PMCID: PMC6335695 DOI: 10.1186/s12957-019-1563-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2018] [Accepted: 01/09/2019] [Indexed: 01/26/2023] Open
Abstract
BACKGROUND Anastomotic leakage (AL) following colorectal resection is a serious issue. AL in oncologic patients might negatively affect the overall survival. Recently, mechanical bowel preparation with additive oral antibiotics (MBP + AB) prior to surgery has been suggested as a means of reducing AL. However, it is unclear whether this positive effect is secondary to MBP alone or secondary to the additive oral antibiotic (MBP + AB). The aim of this study was to investigate the effect of mechanical bowel preparation with additive oral antibiotics (MBP + AB) and without additive oral antibiotics (MBP - AB) on the rate of AL following colorectal resection for cancer. MATERIALS AND METHODS Patients undergoing surgical management for colorectal cancer with anastomosis from January 2014 till September 2017 were included for analysis. Cases undergoing MBP + AB were included in the study group. Patients undergoing MBP - AB were included in the control group. Both groups were compared with regard to the rate of AL. RESULTS Four hundred and ninety-six patients: 125 undergoing MBP + AB and 371 undergoing MBP - AB were included for analysis. Significantly, more male patients were included in the MBP - AB group compared to the MBP + AB group: 60.1% vs. 45.6% respectively (p = 0.03). Both groups were similar with regard to age distribution and clinicopathological findings (p > 0.05). The rate of AL was significantly higher in the control group (MBP - AB) compared to study group (MBP + AB) (9.1% vs. 4.0%, p = 0.03). CONCLUSION Mechanical bowel preparation with additive oral antibiotics prior to elective colorectal resection with anastomosis significantly reduces the risk of AL. Therefore, mechanical bowel preparation with additive non-absorbable oral antibiotics should be recommended in all cases prior to elective colorectal surgery.

Abstract
BACKGROUND Conversion and anastomotic leakage in colorectal cancer surgery have been suggested to have a negative impact on long-term oncologic outcomes. The aim of this study in a large Dutch national cohort was to analyze the influence of conversion and anastomotic leakage on long-term oncologic outcome in rectal cancer surgery. METHODS Patients were selected from a retrospective cross-sectional snapshot study. Patients with a benign lesion, distant metastasis, or unknown tumor or metastasis status were excluded. Overall (OS) and disease-free survival (DFS) were compared between laparoscopic, converted, and open surgery as well as between patients with and without anastomotic leakage. RESULTS Out of a database of 2095 patients, 638 patients were eligible for inclusion in the laparoscopic, 752 in the open, and 107 in the conversion group. A total of 746 patients met the inclusion criteria and underwent low anterior resection with primary anastomosis, including 106 (14.2%) with anastomotic leakage. OS and DFS were significantly shorter in the conversion compared to the laparoscopic group (p = 0.025 and p = 0.001, respectively) as well as in anastomotic leakage compared to patients without anastomotic leakage (p = 0.002 and p = 0.024, respectively). In multivariable analysis, anastomotic leakage was an independent predictor of OS (hazard ratio 2.167, 95% confidence interval 1.322-3.551) and DFS (1.592, 1077-2.353). Conversion was an independent predictor of DFS (1.525, 1.071-2.172), but not of OS. CONCLUSION Technical difficulties during laparoscopic rectal cancer surgery, as reflected by conversion, as well as anastomotic leakage have a negative prognostic impact, underlining the need to improve both aspects in rectal cancer surgery.

Abstract
INTRODUCTION Anastomotic leakage is one of the most severe early complications after colorectal surgery, and it is associated with a high reoperation rate-, and increased in short-term morbidity and mortality rates. It remains unclear whether anastomotic leakage is associated with poor oncologic outcomes. The aim of this study was to determine the impacts of anastomotic leakage on long-term oncologic outcomes, disease-free survival and overall mortality in patients who underwent curative surgery for colorectal cancer. METHODS This single-centre, retrospective, observational cohort study included patients who underwent curative surgery for colorectal cancer between 2005 and 2015 and who had a primary anastomosis. Survival- and multivariate cox regression analyses were performed to adjust for confounding. RESULTS A total of 1984 patients had a primary anastomosis after surgery. The overall incidence of anastomotic leakage was 7.5%; 19 patients were excluded because they were lost to follow-up. Of the remaining 1965 patients, 41 (2.1%) developed local recurrence associated with anastomotic leakage [adjusted hazard ratio (HR) = 2.25; 95% confidence interval (CI) 1.14-5.29; P = 0.03]. Distant recurrence developed in 291(14.8%) patients with no association with anastomotic leakage [adjusted HR = 1.30 (95% CI: 0.85-1.97) P = 0.23]. Anastomotic leakage was associated with increased long-term mortality [adjusted HR = 1.69 (95% CI 1.32-2.18) P < 0.01]. Five year disease-free survival was significantly decreased in patients with anastomotic leakage, (log rank test P < 0.01). CONCLUSION Anastomotic leakage was significantly associated with increased rates of local recurrence, disease free-survival and overall mortality. Associations of anastomotic leakage with distant recurrence was not found.

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.

Standardization of surgical procedures to reduce risk of anastomotic leakage, reoperation, and surgical site infection in colorectal cancer surgery: a retrospective cohort study of 1189 patients. Int J Colorectal Dis 2018; 33:755-762. [PMID: 29602975 DOI: 10.1007/s00384-018-3037-3] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/25/2018] [Indexed: 02/04/2023]
Abstract
PURPOSE Anastomotic leakage (AL) and surgical site infection (SSI) are prevalent complications of colorectal surgery. To lower this risk, we standardized our surgical procedures in 2012, with a preferential use of laparoscopic approach (LS) for both colon and rectal surgery, combined with triangulating anastomosis (TA) for colon surgery and defunctioning ileostomy (DI) for low anterior resection. Our aim was to evaluate the outcomes of our standardized procedures. METHODS The incidence rate of AL (primary outcome) and of reoperation and SSI (secondary outcome) was compared before (early period, n = 648) and after (late period, n = 541) standardization, through a retrospective analysis. RESULTS The incidence rate of AL (6.6 versus 1.8%; P = 0.001), reoperation (3.5 versus 0.7%; P = 0.0012), and SSI (7.7 versus 4.6%; P = 0.029) was lower in late than in the early period. For colon cancer, TA and LS reduced the risk of AL (2.1 versus 0.3%, P = 0.020, for TA, and 3.2 versus 0.4%, P = 0.0027, for LS) and reoperation (2.9 versus 0.3%, P = 0.003, for TA, and 2.5 versus 0.2%, P = 0.0040, for LS). For rectal cancer, the incidence of all adverse outcomes (AL, reoperation, and SSI) was lower in cases treated by LS. However, the incidence of AL was lower in the late than in early period (P = 0.002) and with LS (P = 0.002). On multivariate analysis, late period and LS were independent factors of a lower risk of adverse outcomes. CONCLUSIONS Our surgical standardization seems to be effective in lowering the risks of AL, reoperation, and SSI after colorectal cancer surgery.

Abstract
Background The impact of a patient's gender on the development of anastomotic leak (AL) in rectal cancer patients following total mesorectal excision (TME) remains controversial. The aim of this study was to evaluate the association between patients' gender and the risk of AL. Methods All rectal cancer patients following TME with a primary anastomosis during the study period from 2010 to 2014 were examined. Comparisons of the post-operative AL incidence rate between male and female patients were performed. Results Of all patients examined (n = 956), 587 (61.4%) were males and 369 (38.6%) were females. Male patients were more likely to have a history of smoking and drinking alcohol, but less likely to have a history of abdominal surgery compared to female patients. A higher incidence rate of pre-operative bowel obstruction and larger tumor volume in male patients was observed in our study. Of all the patients, 81 (8.5%) developed post-operative AL. More male patients (n = 62, 10.6%) suffered from AL than females (n = 19, 5.1%) (P = 0.003). Multivariate logistic regression analyses confirmed the association between male gender and AL [odds ratio (OR): 2.41, 95% confidence interval (CI): 1.37-4.23, P = 0.002]. Similar results were also obtained in patients who underwent laparoscopic TME (OR: 2.11, 95% CI: 1.15-3.89, P = 0.016). Conclusions Male patents were found to have an increased risk for AL following TME with a primary anastomosis. A temporary protecting stoma may help to protect the anastomosis and lessen the risk for AL especially in male patients.

Abstract
BACKGROUND The interval between surgery and adjuvant chemotherapy (AC) is a predictive factor of survival in high-risk colon cancer (CC). This study aimed to evaluate the impact of intraoperative sentinel lymph node (SLN) analysis using the one-step nucleic acid amplification (OSNA) technique on the time interval between surgery and AC. METHODS We performed a prospective study analyzing 56 consecutive patients who had surgery for CC between July 2012 and October 2014, including 20 patients needing AC. SLN status was determined intraoperatively in 17 patients in the OSNA group; when positive, a portacath (PAC) was placed during the procedure for upcoming AC. In the remaining patients, we proceeded without SLN status determination and the PAC was installed after definitive histopathological analysis of the specimen if needed. RESULTS There was no difference between the groups regarding cancer staging, duration of hospitalization (7.5days in the OSNA group and 10days in the control group, p=0.43) and major complications (20% vs 30% respectively, p=0.55). The time interval between surgery and adjuvant chemotherapy was significantly shorter in the OSNA group at 35 (±8) days vs 67 (±36) days (p=0.021). CONCLUSION SLN status determination by the OSNA technique is safe, feasible and could significantly reduce time between surgery and adjuvant chemotherapy in a pilot study.

[PMID: 28411352 DOI: 10.1007/s00384-017-2811-y] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 04/05/2017] [Indexed: 02/04/2023]
Abstract
PURPOSE It is well known that specific postoperative complications such as stroke influence readmissions and overall survival (OS) after surgery for colorectal cancer (CRC). Whether overall hospital morbidity is associated with increased risk of readmission and poorer long-term survival is unknown. New tools are available to accurately quantify overall morbidity, such as the comprehensive complication index (CCI). The aim is to evaluate the impact of complications on readmission and overall survival (OS) in patients operated for colorectal cancer. METHODS Postoperative complications of patients undergoing surgery for CRC were assessed over a 5-year period using the Clavien-Dindo classification, and overall morbidity was assessed by using the CCI. Individual scores were analyzed regarding their association with readmission and OS by using the multivariate logistic and Cox proportional-hazards regression analysis, respectively. RESULTS Two hundred eighty-four patients were operated for CRC, of which 22 (8%) were readmitted. One hundred five patients (37%) developed at least one postoperative complication during the hospital stay. While single complications or the use of severe complication only (grade ≥IIIb) was not associated with readmission, overall morbidity (CCI) predicted readmission (OR 1.02 (95% CI 1.0-1.04), p = 0.044). Similarly, morbidity assessed by the CCI had a significant negative predictive value on OS, e.g., patients with a CCI of 20 were 22% more likely to die within a 5-year follow-up, when compared to patients with a CCI of 10 (p = 0.022). CONCLUSIONS Overall combined morbidity as assessed by the CCI leads to more frequent readmission, and is associated with poorer long-term survival after surgery for CRC.

Ann Gastroenterol Surg 2017; 1:11-23.

Abstract
PURPOSE The impact of postoperative complications on survival after radical surgery for esophageal, gastric, and colorectal cancers remains controversial. We conducted a systematic review of recent publications to examine the effect of postoperative complications on oncological outcome. METHODS A literature search of PubMed/MEDLINE was performed using the keywords "esophageal cancer," "gastric cancer," and "colorectal cancer," obtaining 27 reports published online up until the end of April 2016. Articles focusing on (i) postoperative morbidity and oncological outcome; and (ii) body mass index (BMI), postoperative morbidity, and oncological outcome, were selected. Univariate and multivariate analyses (Cox proportional hazards model) were performed. RESULTS Patients with postoperative complications had significantly poorer long-term survival than those without complications. Complications were associated with impaired oncological outcomes. The hazard ratios for overall survival were 1.67 (95% confidence interval [CI], 1.31-2.12), 1.59 (95% CI, 1.13-2.24), and 1.55 (95% CI, 1.28-1.87) in esophageal, gastric, and colorectal cancers, respectively. High BMI was associated with postoperative morbidity rate but not with poor oncological outcome. Low BMI was significantly associated with inferior oncological outcome. CONCLUSIONS Complications after radical surgery for esophageal, gastric, and colorectal cancers are associated with patient prognosis. Avoiding such complications might improve the outcomes.

Abstract
BACKGROUND Anastomotic leakage (AL) is the most dreaded complication after colorectal surgery, causing high morbidity and mortality. Mucus is a first line of defence against external factors in the gastrointestinal tract. In this study, the structural mucus protein Muc2 was depleted in genetically engineered mice and the effect on healing of colonic anastomoses studied in an experimental model. METHODS Mice of different Muc2 genotypes were used in a proximal colonic AL model. Tissues were scored histologically for inflammation, bacterial translocation was determined by quantitative PCR of bacterial 16S ribosomal DNA, and epithelial cell damage was determined by assessing serum levels of intestinal fatty acid-binding protein. RESULTS Of 22 Muc2-deficient (Muc2-/- ) mice, 20 developed AL, compared with seven of 22 control animals (P < 0·001). Control mice showed normal healing, whereas Muc2-/- mice had more inflammation with less collagen deposition and neoangiogenesis. A tendency towards higher bacterial translocation was seen in mesenteric lymph nodes and spleen in Muc2-/- mice. Intestinal fatty acid-binding protein levels were significantly higher in Muc2-/- mice compared with controls (P = 0·011). CONCLUSION A functional mucous layer facilitates the healing of colonic anastomoses. Clinical relevance Colorectal anastomotic leakage remains the most dreaded complication after colorectal surgery. It is known that the aetiology of anastomotic leakage is multifactorial, and a role is suggested for the interaction between intraluminal content and mucosa. In this murine model of proximal colonic anastomotic leakage, the authors investigated the mucous layer at the intestinal mucosa, as the first line of defence, and found that a normal, functioning mucous layer is essential in the healing process of colonic anastomoses. Further research on anastomotic healing should focus on positively influencing the mucous layer to promote better postoperative recovery.

Abstract
PURPOSE The aim of this study was to explore the choice of modality for diagnosis, treatments, and consequences of anastomotic leakage. METHODS This is a retrospective study of consecutive patients who underwent surgery that included a colorectal anastomosis due to colorectal cancer, diverticulitis, inflammatory bowel disease (IBD), or benign polyps. RESULTS A total of 600 patients were included during 2010-2012, and 60 (10%) had an anastomotic leakage. It took in mean 8.8 days (range 2-42) until the anastomotic leakage was diagnosed. A total of 44/60 of the patients with a leakage had a CT scan of the abdomen; 11 (25%) were initially negative for anastomotic leakage. Among all leakages, the anastomosis was taken down in 45 patients (76.3%). All patients with a grade B leakage (n = 6) were treated with antibiotics, and two also received transanal drainage. The overall complication rate was also significantly higher in those with leakage (93.3 vs. 28.5%, p < 0.001), and it was more common with more than three complications (70 vs. 1.5%, p < 0.001). There was a higher mortality in the leakage group. CONCLUSION This study demonstrated that one fourth of the CT scans that were executed were initially negative for leakage. Most patients with a grade C leakage will not have an intact anastomosis. An anastomotic leakage leads to significantly more severe postoperative complications, higher rate of reoperations, and higher mortality. An earlier relaparotomy instead of a CT scan and improved postoperative surveillance could possibly reduce the consequences of the anastomotic leakage.

Abstract
INTRODUCTION Despite extensive research, anastomotic leakage (AL) remains one of the most dreaded complications after colorectal surgery. Since butyrate enemas are known to enhance anastomotic healing, several administration routes have been explored in this study. METHODS Three intraluminal approaches involving butyrate were investigated: (1) butyrin-elucidating patch, (2) a single injection of hyaluronan-butyrate (HA-But) prior to construction of the proximal anastomosis and (3) rectal hyaluronan-butyrate (HA-But) enemas designed for distal anastomoses. The main outcome was AL and secondary outcomes were bursting pressure, histological analysis of the anastomosis, zymography to detect MMP activity and qPCR for gene expression of MMP2, MMP9, MUC2 and TFF3. RESULTS Neither the patches nor the injections led to a reduction of AL in experiments 1 and 2. In experiment 3, a significant reduction of AL was accomplished with the (HA-But) enema compared to the control group together with a higher bursting pressure. Histological analysis detected only an increased inflammation in experiment 2 in the hyaluronan injection group compared to the control group. No other differences were found regarding wound healing. Zymography identified a decreased proenzyme of MMP9 when HA-But was administered as a rectal enema. qPCR did not show any significant differences between groups in any experiment. CONCLUSION Butyrate enemas are effective in the enhancement of colonic anastomosis. Enhanced butyrate-based approaches designed to reduce AL in animal models for both proximal and distal anastomoses were not more effective than were butyrate enemas alone. Further research should focus on how exogenous butyrate can improve anastomotic healing after gastrointestinal surgery.

Abstract
Anastomotic leaks represent one of the most alarming complications following any gastrointestinal anastomosis due to the substantial effects on post-operative morbidity and mortality of the patient with long-lasting effects on the functional and oncologic outcomes. There is a lack of consensus related to the definition of an anastomotic leak, with a variety of options for prevention and management. A number of patient-related and technical risk factors have been found to be associated with the development of an anastomotic leak and have inspired the development of various preventative measures and technologies. The International Multispecialty Anastomotic Leak Global Improvement Exchange group was convened to establish a consensus on the definition of an anastomotic leak as well as to discuss the various diagnostic, preventative, and management measures currently available.

Abstract
BACKGROUND There is conflicting evidence regarding the oncological impact of anastomotic leak following colorectal cancer surgery. This study aims to test the hypothesis that anastomotic leak is independently associated with local recurrence and overall and cancer-specific survival. METHODS Analysis of prospectively collected data from multiple centres in Victoria between 1988 and 2015 including all patients who underwent colon or rectal resection for cancer with anastomosis was presented. Overall and cancer-specific survival rates and rates of local recurrence were compared using Cox regression analysis. RESULTS A total of 4892 patients were included, of which 2856 had completed 5-year follow-up. The overall anastomotic leak rate was 4.0%. Cox regression analysis accounting for differences in age, sex, body mass index, American Society of Anesthesiologists score and tumour stage demonstrated that anastomotic leak was associated with significantly worse 5-year overall survival (χ 2 = 6.459, P = 0.011) for colon cancer, but only if early deaths were included. There was no difference in 5-year colon cancer-specific survival (χ 2 = 0.582, P = 0.446) or local recurrence (χ 2 = 0.735, P = 0.391). For rectal cancer, there was no difference in 5-year overall survival (χ 2 = 0.266, P = 0.606), cancer-specific survival (χ 2 = 0.008, P = 0.928) or local recurrence (χ 2 = 2.192, P = 0.139). CONCLUSION Anastomotic leak may reduce 5-year overall survival in colon cancer patients but does not appear to influence the 5-year overall survival in rectal cancer patients. There was no effect on local recurrence or cancer-specific survival.

Abstract
BACKGROUND Accumulating evidence suggests that peritoneal cytokine concentrations may predict anastomotic leak after colorectal surgery, but previous studies have been underpowered. OBJECTIVE We aimed to test this hypothesis by using a larger prospectively collected data set. DESIGN This study is an analysis of prospectively collected data. SETTINGS This study was conducted at 3 public hospitals in Auckland, New Zealand. PATIENTS Patients undergoing colorectal surgery recruited as part of 3 previous randomized controlled trials were included. MAIN OUTCOME MEASURES Data on peritoneal and plasma levels of interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-α on day 1 after colorectal surgery were reanalyzed to evaluate their predictive value for clinically important anastomotic leak. Area under receiver operating characteristic curve analysis was performed. RESULTS A total of 206 patients with complete cytokine data were included. The overall anastomotic leak rate was 8.3%. Concentration levels of peritoneal interleukin-6 and interleukin-10 on day 1 after colorectal surgery were predictive of anastomotic leak (area under receiver operating characteristic curve, 0.72 and 0.74; p = 0.006 and 0.004). Plasma cytokine levels of interleukin-6 were higher on day 1 after colorectal surgery in patients who had an anastomotic leak, but this was a poor predictor of anastomotic leak. Levels of other peritoneal and plasma cytokines were not predictive. LIMITATIONS The study was not powered a priori for anastomotic leak prediction. Although the current data do suggest that peritoneal levels of interleukin-6 and interleukin-10 are predictive of leak, the discriminative value in clinical practice remains unclear. CONCLUSIONS Peritoneal levels of interleukin-6 and interleukin-10 on day 1 after colorectal surgery can predict clinically important anastomotic leak.

Abstract
BACKGROUND The benefits of adjuvant chemotherapy in the treatment of colorectal cancer are well established. Chemotherapy-induced diarrhea is a common adverse effect of these regimens. The occurrence of chemotherapy-induced diarrhea not only directly affects patient health but may also compromise treatment efficacy because of consequent dosing alterations or discontinuation. OBJECTIVE This study aimed to investigate the effect of diverting loop ileostomy during chemotherapy on the occurrence and consequences of chemotherapy-induced diarrhea. DESIGN This was a retrospective evaluation of a prospective surgical database. SETTINGS This was a single-institution retrospective study. PATIENTS All patients receiving curative adjuvant chemotherapy after anterior resection for colorectal cancer at Auckland Hospital from 2002 to 2013 were retrospectively evaluated. MAIN OUTCOME MEASURES Patient-, perioperative-, and chemotherapy-related variables were collected. Chemotherapy-induced diarrhea occurrence was graded according to National Cancer Institute Common Terminology Criteria for Adverse Events. Logistic regression analysis was performed to identify independent predictors for chemotherapy-induced diarrhea occurrence, treatment modifications, and hospital admission. RESULTS A total of 109 identified patients received 691 chemotherapy cycles; 84% of patients with a diverting ileostomy experienced chemotherapy-induced diarrhea compared with 47% in those who were not defunctioned (p < 0.01). On logistic regression analysis, the presence of a diverting ileostomy during chemotherapy was an independent predictor of chemotherapy-induced diarrhea grade 3 or higher (OR, 13.6 (95% CI: 1.2-150.9); p = 0.02), the need for a dosing reduction (OR, 4.0 (95% CI: 1.3-12.4); p = 0.02), and the need for any modification in the chemotherapy regimen (OR, 3.4 (95% CI: 1.2-9.6); p = 0.02). LIMITATIONS This study is limited by its retrospective design, potentially limiting the accuracy of chemotherapy-induced diarrhea grade reporting. CONCLUSIONS The presence of an ileostomy during adjuvant chemotherapy is a predictor of severe chemotherapy-induced diarrhea and the need for modifications in the chemotherapy regimen. This may have important consequences for long-term survival. Prospective investigation is needed to further assess the impact of diverting ileostomy on the delivery of chemotherapy and oncologic outcomes.

Abstract
BACKGROUND The prognostic nutritional index is reportedly related to postoperative outcomes. OBJECTIVE The aim of this study was to elucidate the clinical importance of the prognostic nutritional index in patients with colorectal cancer who were undergoing primary tumor resection. DESIGN This is a retrospective study from a single institution. SETTINGS This study was conducted at a colorectal surgery service in an academic teaching hospital. PATIENTS The 556 patients with colorectal cancer who were undergoing surgery between March 2005 and August 2014 were eligible for this study. MAIN OUTCOME MEASURES The preoperative prognostic nutritional index was calculated. Classification and regression tree analysis was performed to determine the prognostic nutritional index cutoff value. The associations of the prognostic nutritional index status with clinicopathological factors and postoperative outcomes were examined using univariate and multivariate analyses. RESULTS Classification and regression tree analysis demonstrated that 45.5 was the optimal cutoff value. The low status (≤45.5) was correlated with older age, low BMI, low estimated glomerular filtration rate, CEA positivity, carbohydrate antigen 19-9 positivity, preoperative chemotherapy, tumors invading muscular or deeper layers, distant metastasis, poor differentiation, severe postoperative complications, tumor recurrence, and poor survival. In multivariate analysis, the low status was an independent risk factor for severe postoperative complications (OR = 2.06 [95% CI, 1.22-3.50]; p = 0.007) and low overall survival (HR =3.98 [95% CI, 2.38-6.89]; p < 0.001). LIMITATIONS Our data set was collected retrospectively from a single institution. In addition, our study was only for preoperative prognostic nutritional index status, not considering the postoperative host status. CONCLUSIONS The preoperative prognostic nutritional index predicts severe complications, recurrence, and poor prognosis in patients with colorectal cancer who are undergoing primary tumor resection. Investigation of the nutritional and immunologic statuses using the prognostic nutritional index could be a useful clinical approach.
