BackgroundAlthough evidence suggests that laparoscopic colectomy (LC) results in faster gastrointestinal (GI) recovery than open bowel resection, previous studies were performed at single institutions or generally not controlled for diet introduction or perioperative care, making the results difficult to interpret. A prospective, observational, multicenter study was planned to investigate GI recovery, length of hospital stay (LOS), and postoperative ileus (POI)-related morbidity after LC.MethodsPatients scheduled to undergo LC or hand-assisted laparoscopic (HAL) bowel resection and to receive opioid-based postoperative intravenous patient-controlled analgesia were enrolled in 16 U.S. centers. The study design was similar to that for trials of alvimopan phase 3 open laparotomy bowel resection using a standardized accelerated postoperative care pathway. The primary end points were time to upper and lower GI recovery (GI-2: toleration of solid food and bowel movement) and postoperative LOS. The secondary end points included POI-related morbidity (postoperative nasogastric tube insertion or investigator-assessed POI resulting in prolonged hospital stay or readmission), conversion rate, and protocol-defined prolonged POI (GI-2 > 5 postoperative days).ResultsIn this study, 148 patients received hemicolectomy by the LC (42 left and 67 right) or HAL (39 left) approach. The conversion rate was 18.8% (25.4% LC left, 17.3% HAL left, 15% LC right). The mean time to GI-2 recovery was 4.4 days, and the mean postoperative LOS was 4.9 days, neither of which varied substantially by surgical approach. Prolonged POI occurred for 15 patients (10.1%), and POI-related morbidity occurred for 17 patients (11.5%). No patients were readmitted because of POI, whereas 3 patients (2%) were readmitted for all other causes.ConclusionsMean GI recovery and LOS after LC were accelerated compared with those for patients in open laparotomy bowel resection clinical trials or those reported in large hospital databases (0.7 and 1.7-2.2 days, respectively). Overall POI-related morbidity was similar between the open bowel resection and LC populations, demonstrating that POI continues to present with important morbidity regardless of the surgical approach.
