Complications and postoperative ileus in laparoscopic versus open colectomy: A retrospective cohort study

Background: Postoperative complications are a major concern after colorectal surgery, and can lead to an increased burden on patients and the healthcare system. Complications include postoperative ileus (POI) and prolonged postoperative ileus (PPOI). There are well-established risk factors and potential modifiable risk factors that affect the incidence of POI and PPOI, including invasive techniques, operative difficulty, perioperative blood loss, and delayed mobilization. We compared the incidence of POI, PPOI, and other postoperative complications between laparoscopic colectomy and open colectomy. Methods: This retrospective review investigates 120 patients who underwent either laparoscopic or open colectomy in King Abdulaziz University Hospital in Jeddah, Saudi Arabia, between January 2016 and June 2019. Data were collected from patients’ electronic medical records. Patients were classified into laparoscopic and open colectomy groups. The main outcomes of interest were POI, PPOI and the overall complication rate. These outcomes were calculated and compared between the two groups. Results: The overall incidence of POI and PPOI was 4.2% and 15%, respectively. There was a higher incidence of POI in the laparoscopic approach group (7.2% vs. 1.5%, P=0.03); however, the incidence of PPOI was higher in the open approach group (20% vs. 9.1%, P=0.03). The open surgery group showed a higher rate of overall complications (P=0.001). The mean estimated blood loss was lower in the laparoscopy group (139.09±145.83 vs. 343.85±307.78 mL; P<0.001). Significant earlier mobilization was observed in the laparoscopic group (3.12±1.77 vs. 5.39±3.48 days; P
