Colorectal Resection After Stent Insertion for Obstructing Cancer

Comparison Between Open and Laparoscopic Approaches

Abstract

Aim: 

To evaluate surgical outcomes after stent insertion for obstructing colorectal malignancy and to compare between laparoscopic and open approach.

Methods: 

Surgical resection was performed after stent insertion for malignant colorectal obstruction in 36 patients with a median age of 73 years. Eighteen patients were treated with open resection, whereas 18 underwent a laparoscopic resection. The outcomes were evaluated and comparison was made between patients with laparoscopic and open resection.

Results: 

The mean interval between stent insertion and surgery was 11 days. One patient died within 30 days (2.8%). The overall incidence of postoperative morbidity was 22% and reoperation was required in 3 patients (8.8%). The median postoperative hospital stay was 8.5 days for the open surgery group and 5.5 days for the laparoscopic group (P=0.004). The postoperative morbidity rates for the open and laparoscopic groups were 33.3% and 11.1%, respectively (P=0.228). In those patients with nonmetastatic disease, with the median follow-up of 20 months, the 5-year survival rate was 49.5%.

Conclusions: 

Our experience showed that after successful endoscopic stent insertion for malignant colorectal obstruction, elective surgical resection could be performed safely. The combined endoscopic and laparoscopic procedure provides a less invasive alternative to the multistage open operations and is feasible for patients with obstructing colon cancer.
