BACKGROUND: Anastomotic leak after sigmoidectomy for diverticular disease can have devastating consequences. Preservation or sacrifice of the descending colon or rectal arterial supply may affect the anastomosis. The aim of this study was to evaluate whether preservation of the inferior mesenteric artery (IMA) or superior rectal artery (SRA) was associated with a decreased anastomotic leak rate.
METHODS: A retrospective review of adult patients undergoing sigmoidectomies from 2 military tertiary care centers was performed, evaluating patient demographic and operative variables for their effects on anastomotic leak rate.
RESULTS: A total of 130 patients were identified. The overall anastomotic leak rate was 5.4%. Laparoscopy was used in 41%, and stapled anastomoses were used in 91%. The IMA was sacrificed in 29% and the SRA in 37%. There were no significant differences in leak rates when the IMA or SRA was sacrificed (0% and 3.7% with the IMA and SRA sacrificed, 9.3% and 6.5% with the vessels preserved; P = .140 and P = .610, respectively). Laparoscopic technique (P = .843), emergency surgery (P = .29), and operative time (P = .78) did not affect leak rate. Hand-sewn anastomoses were associated with a higher leak rate (33% vs 2%; odds ratio, 3.44; 95% confidence interval, 1.514-7.817; P < .001).
CONCLUSIONS: IMA or SRA preservation or sacrifice was not associated with an increased leak rate from colorectal anastomoses after sigmoidectomy for diverticular disease. Stapled anastomoses were associated with a lower leak rate than hand-sewn anastomoses.
