Comparison between open and laparoscopic reversal of Hartmann’s procedure for diverticulitis

Abstract

To compare the open and laparoscopic Hartmann's reversal in patients first treated for complicated diverticulitis. Forty-six consecutive patients with diverticular disease were included in this retrospective, single-center study of a prospectively maintained colorectal surgery database. All patients underwent conventional Hartmann's procedures for acute complicated diverticulitis. Other indications for Hartmann's procedures were excluded. Patients underwent open (OHR) or laparoscopic Hartmann's reversal (LHR) between 2000 and 2010, and received the same pre- and post-operative protocols of cares. Operative variables, length of stay, short- (at 1 mo) and long-term (at 1 and 3 years) post-operative complications, and surgery-related costs were compared between groups. The OHR group consisted of 18 patients (13 males, mean age ± SD, 61.4 ± 12.8 years), and the LHR group comprised 28 patients (16 males, mean age 54.9 ± 14.4 years). The mean operative time and the estimated blood loss were higher in the OHR group (235.8 ± 43.6 min vs 171.1 ± 27.4 min; and 301.1 ± 54.6 mL vs 225 ± 38.6 mL respectively, P = 0.001). Bowel function returned in an average of 4.3 ± 1.7 d in the OHR group, and 3 ± 1.3 d in the LHR group (P = 0.01). The length of hospital stay was significantly longer in the OHR group (11.2 ± 5.3 d vs 6.7 ± 1.9 d, P < 0.001). The 1 mo complication rate was 33.3% in the OHR (6 wound infections) and 3.6% in the LHR group (1 hemorrhage) (P = 0.004). At 12 mo, the complication rate remained significantly higher in the OHR group (27.8% vs 10.7%, P = 0.03). The anastomotic leak and mortality rates were nil. At 3 years, no patient required re-intervention for surgical complications. The OHR procedure had significantly higher costs (+56%) compared to the LHR procedure, when combining the surgery-related costs and the length of hospital stay. LHR appears to be a safe and feasible procedure that is associated with reduced hospitality stays, complication rates, and costs compared to OHR.
