The role of laparoscopic surgery for patients with ileocecal Crohn’s disease is a contentious issue. This metaanalysis aimed to compare open resection with laparoscopically assisted resection for ileocecal Crohn’s disease. A literature search of the Medline, Ovid, Embase, and Cochrane databases was performed to identify comparative studies reporting outcomes for both laparoscopic and open ileocecal resection. Metaanalytical techniques were applied to identify differences in outcomes between the two groups. Sensitivity analysis was undertaken to evaluate the heterogeneity of the study. Of 20 studies identified by literature review, 15 satisfied the criteria for inclusion in the study. These included outcomes for 783 patients, 338 (43.2%) of whom had undergone laparoscopic resection, with an overall conversion rate to open surgery of 6.8%. The operative time was significantly longer in the laparoscopic group, by 29.6 min (p = 0.002), although the blood loss and complications in the two groups were similar. In terms of postoperative recovery, the laparoscopic patients had a significantly shorter time for recovery of their enteric function and a shorter hospital stay, by 2.7 days (p < 0.001). For selected patients with noncomplicated ileocecal Crohn’s disease, laparoscopic resection offered substantial advantages in terms of more rapid resolution of postoperative ileus and shortened hospital stay. There was no increase in complications, as compared with open surgery. The contraindications to laparoscopic approaches for Crohn’s disease remain undefined.

Objective: To compare primary resection and anastomosis (PRA) with and without defunctioning stoma to Hartmann's procedure (HP) as the optimal operative strategy for patients presenting with Hinchey stage III-IV, perforated diverticulitis. Summary Background Data: The choice of operation for perforated diverticulitis lies between HP and PRA. Postoperative mortality and morbidity can be high, and the long-term consequences life-altering, with no established criteria guiding clinicians towards selecting a particular procedure. Methods: Probability estimates for 6879 patients with Hinchey III-IV perforated diverticulitis were obtained from two databases (n = 204), supplemented by expert opinion and summary data from 12 studies (n = 6675) published between 1980 and 2005. The primary outcome was quality-adjusted life-years (QALYs) gained from each strategy. Factors considered were the risk of permanent stoma, morbidity, and mortality from the primary or reversal operations. Decision analysis from the patient's perspective was used to calculate the optimal operative strategy and sensitivity analysis performed. Results: A total of 135 PRA, 126 primary anastomoses with defunctioning stoma (PADS), and 6619 Hartmann's procedures (HP) were considered. The probability of morbidity and mortality was 55% and 30% for PRA, 40% and 25% for PADS, and 35% and 20% for HP, respectively. Stomas remained permanent in 27% of HP and in 8% of PADS. Analysis revealed the optimal strategy to be PADS with 9.98 QALYs, compared with 9.44 QALYs after HP and 9.02 QALYs after PRA. Complications after PRA reduced patients QALYs to a baseline of 2.713. Patients with postoperative complications during both primary and reversal operations for PADS and HP had QALYs of 0.366 and 0.325, respectively. HP became the optimal strategy only when risk of complications after PRA and PADS reached 50% and 44%, respectively. Conclusion: Primary anastomosis with defunctioning stoma may be the optimal strategy for selected patients with diverticular peritonitis as may represent a good compromise between postoperative adverse events, long-term quality of life and risk of permanent stoma. HP may be reserved for patients with risk of complications >40% to 50% after consideration of long-term implications.
