Context: The occurence of anastomotic leakage after gastointestinal resection and anastomosis is associated with significant mortality and morbidity. Aims: There is dearth of evidence in the literature on the influence of various non-surgical factors in causing anastomotic leakage although many studies have identified their possible role. Materials and Methods: A retrospective audit of all the anastomotic leakages occurring between September 2009 and April 2012 in our institute was performed to identify the potential non-surgical factors that can influence anastomotic leakage. A total of 137 out of 1246 patients who developed anastmotic leak were analyzed. All the potential non-surgical causes of anastomotic leakage available in the literature were analyzed by univariate analysis and stepwise multiple logistic regression analysis was done after adjusting for the type of surgery. An intergroup comparison among the patients based on the type of surgery was also performed. Results: The following factors were found to be independently associated with increased risk of anastomotic leak: (1) albumin <3.5 g/dl, (2) anemia <8 g/dl, (3) hypotension (4) use of inotropes, and (5) blood transfusion. The majority of anastomotic leaks occurred after pancreatic surgeries followed by esophagectomies and occurred least after colonic resections.The risk for anastomotic leak was four times more in patients who required inotropic support in the perioperative period and three times more in patients who developed hypotension. Conclusions: Our study is the first retrospective audit to identify the influence of non-surgical factors for anastomotic leakage and the need for further observational studies in this direction.
