Surgical outcome in patients undergoing reversal of Hartmann's procedures: a multicentre study.

AIM: Recent evidence has suggested that a laparoscopic rather than an open approach to reversal of Hartmann's procedure (ROH) may be associated with fewer complications. Much of the data for comparison are historical or based on small case series. The aims of this study were to determine the morbidity and mortality of ROH in 10 hospitals in the modern era and to identify risk factors for complications.
METHOD: A multicentre study of patients undergoing ROH (2007-2013) was performed. Data were collected retrospectively from perioperative health databases and casenotes where appropriate on patient demographics, laboratory investigations and operative details. Complications were classified as minor (I-II) or major (III-IV) based on the Clavien-Dindo criteria. Risk factors for complications were assessed by multivariate analysis with calculation of OR with 95% CI.
RESULTS: Ten hospitals in Scotland provided data on 252 patients undergoing ROH. Most operations were open (85%) with 15% started laparoscopically (conversion rate 64%). In the postoperative period, 35 (14%) patients had a major complication, including anastomotic leakage in 10 (4%) and postoperative death in one (0.4%). Patients with a complication stayed significantly longer in hospital (12 days vs 7 days, P < 0.001). On multivariate analysis, a wound complication after the original Hartmann's procedure (OR = 3.85, 95% CI: 1.08-13.75, P = 0.038) was associated with any complication after ROH, but only American Society of Anesthesiologists (ASA) grade (OR = 3.35, 95% CI: 1.38-8.09, P = 0.007) was independently associated with the development of a major complication.
CONCLUSION: ROH has a low postoperative mortality but significant morbidity. Most operations are still performed by open surgery, and in those attempted laparoscopically, the conversion rate is high. Colorectal Disease
