Abstract PDF: Purpose
Malignant large bowel obstruction is a surgical emergency that requires urgent decompression. Stents are increasingly being used, though reported outcomes are variable. We describe our multidisciplinary experience in using stents to manage malignant large bowel obstruction.
Methods
All patients undergoing colorectal stent insertion for acute large bowel obstruction in a teaching hospital were included. Outcomes, complications, and length of stay (LOS) were recorded.
Results
Over a 7-year period, 73 procedures were performed on 67 patients (37 male, mean age of 76 years). Interventional radiology was involved in all cases. Endoscopic guidance was required in 24 cases (32.9%). In 18 patients (26.9%), treatment intent was to bridge to elective surgery; 16 had successful stent placement; all had subsequent curative resection (laparoscopic resection, 8 of 18; primary anastomosis, 14 of 18). Overall LOS, including both index admission and elective admission, was 16.4 days. Treatment intent was palliative in 49 patients (73.1%). In this group, stents were successfully placed in 41 of 49 (83.7%). Complication rate within 30 days was 20%, including perforation (2 patients), per rectal bleeding (2), stent migration (1), and stent passage (5). Nineteen patients (38.8%) required subsequent stoma formation (6, during same admission; 13, during subsequent admission). Overall LOS was 16.9 days.
Conclusion
In our experience colorectal stents can be used effectively to manage malignant large bowel obstruction, with only selective endoscopic input. As a bridge to surgery, most patients can avoid emergency surgery and have a primary anastomosis. In the palliative setting, the complication rate is acceptable and two-thirds avoid a permanent stoma.
