    • Abstract:
      Background: Laparoscopic primary anastomosis (PA) without diversion for diverticulitis has historically been confined to the elective setting. Hartmann's procedure is associated with high morbidity rates that might be reduced with less invasive and one-step approaches. The aim of this study was to analyze the results of laparoscopic PA without diversion in Hinchey III perforated diverticulitis.Methods: We performed a retrospective analysis of a prospectively collected database of all patients who underwent laparoscopic sigmoidectomy for diverticular disease during the period 2000-2018. The sample was divided in two groups: elective laparoscopic sigmoid resection for recurrent diverticulitis (G1) and emergent laparoscopic sigmoidectomy for Hinchey III diverticulitis (G2). Demographics, operative variables, and postoperative outcomes were compared between groups.Results: A total of 415 patients underwent laparoscopic sigmoid resection for diverticular disease. PA without diversion was performed in 351 patients; 278 (79.2%) belonged to G1 (recurrent diverticulitis) and 73 (20.8%) to G2 (perforated diverticulitis). Median age, gender, and BMI score were similar in both groups. Patients with ASA III score were more frequent in G2 (p: 0.02). Conversion rate (G1: 4% vs. G2: 18%, p < 0.001), operative time (G1: 157 min vs. G2: 183 min, p < 0.001), and median length of hospital stay (G1: 3 days vs. G2: 5 days, p < 0.001) were significantly higher in G2. Overall postoperative morbidity (G1: 22.3% vs. G2: 28.7%, p = 0.27) and anastomotic leak rate (G1: 5.7% vs. G2: 5.4%, p = 0.92) were similar between groups. There was no mortality in G1 and one patient (1.3%) died in G2 (p = 0.21).Conclusion: Laparoscopic sigmoid resection without diversion is feasible and safe in patients with perforated diverticulitis. In centers with vast experience in laparoscopic colorectal surgery, patients undergoing this procedure have similar morbidity and mortality to those undergoing elective sigmoidectomy.
