Morbidity after reversal of Hartmann operation: retrospective analysis of 56 patients.

Abstract

BACKGROUND: Despite patient selection, postoperative morbidity after reversal of Hartmann's procedure remains significant. AIM: The objective of this study was to investigate risk factors associated with morbidity after conversion of Hartmann's operation. PATIENTS AND METHODS: We retrospectively analyzed data of 56 patients who underwent reversal procedures between January 2004 and May 2015 in a single center. We evaluated the following variables: demographic characteristics, medical comorbidities, etiology for Hartmann operation, preoperative lab values, intraoperative surgical details and short-term outcomes (hospital stay, medical and surgical complications, mortality). RESULTS: There were 37 men (66.1%) and the mean age was 57 years. The most frequent indications for Hartmann's procedure were colorectal cancer in 25 patients (44.6%) and complicated diverticulitis in 10 patients (17.9%). The mean time to the reversal procedure was 9 months. Morbidity rate was 16.1% (9 patients) with an anastomotic leakage rate of 3.6% (2 patients) and mortality rate was 3.6% (2 patients). The most common medical complication was diarrhea (4 patients, 7.2%). Bivariate analysis demonstrated that the only factor significantly associated with postoperative complications was presence of multiple comorbidities. CONCLUSIONS: Multiple medical comorbidities is the only predictive factor for postoperative complications after Hartmann's reversal and therefore patient selection for this type of surgery is critical.
