Comparison of short-term outcomes after elective surgery following endoscopic stent insertion and emergency surgery for obstructive colorectal cancer

Abstract

PurposeThe aim of this study was to compare short-term morbidities and mortalities of elective surgery after stent insertion and emergency surgery in obstructive colorectal cancer. MethodsWe retrospectively reviewed 77 patients with obstructive colorectal cancer that underwent elective surgery after stenting (stent group: SG, n = 49) or emergent surgery (emergency group: EG, n = 28) from January 2000 to July 2010. ResultsThe American Society of Anesthesiologists (ASA) score of SG was lower than that of EG (p = 0.015). The percentages of open and laparoscopic surgery in SG were 73.5% (36/49) and 26.5% (13/49), respectively, whereas surgery in EG was performed using an open technique (p = 0.003). The rate of primary anastomosis, without constructing a stoma, was 87.8% in SG and 42.9% in EG (p < 0.001). There was no difference in a postoperative complication. Anastomotic leakage according to time between stent placement and surgery in SG were 3 cases for 1–9 days and 0 for more than 10 days (p = 0.037). Three-year overall survival rates were 68.8% and 51.3% (p = 0.430), respectively. ConclusionPreoperative stent insertion in obstructive colorectal cancer seems to be safe and feasible, and may decrease second stage procedure. Waiting 10 days after stent placement may be a more optimal time for surgical intervention. Further prospective randomized studies are needed to determine the proper time bridge to surgery following stent insertion in obstructive colorectal cancer.
