Evaluating outcomes of primary anastomosis versus Hartmann's procedure in sigmoid volvulus: A retrospective-cohort study

Background: The aim of this study is to compare the short outcomes of two methods of sigmoid resection and primary anastomosis with sigmoid resection and end colostomy (Hartmann's procedure) for sigmoid volvulus. Methods: This retrospective study included 102, of which 56 patients underwent end colostomy (Hartmann's procedure) and 46 patients underwent resection and primary anastomosis for sigmoid volvulus. The medical records of the patients were reviewed to evaluate the patients' characteristics, operative data, short-term postoperative outcomes and mortality. Results: The mean age of patients in the groups of Hartmann's procedure and primary anastomosis were 68.23 +/- 13.42 and 70.10 +/- 12.71, respectively. From the 46 patients who had primary colorectal anastomosis, 2 patients (4.3%) suffered from anastomosis leakage, which was not significantly different. This study showed that anastomosis leakage, prolonged ileus, bleeding, surgical site infection and fascial dehiscence were not different between Hartmann's procedure and primary anastomosis, significantly, p < 0.05. Hospital stay in the Hartmann group was less than primary anastomosis group in the same admission, p = 0.04. The mortality rate was not statistically different among the two groups, p = 0.549. Conclusions: Postoperative complications and mortality rate do not different among the two groups however, the duration of hospitalization was lesser in Hartmann's procedure group.
