Feasibility and safety of laparoscopic resection following stent insertion for obstructing left-sided colon cancer

Abstract

PURPOSE:

The aim of this study was to assess the feasibility and safety of laparoscopic resection following the insertion of self-expanding metallic stents (SEMS) for the treatment of obstructing left-sided colon cancer.

METHODS:

Between October 2006 and December 2012, laparoscopic resection following SEMS insertion was performed in 54 patients with obstructing left-sided colon cancer.

RESULTS:

All 54 procedures were technically successful without the need for conversion to open surgery. The median interval from SEMS insertion to laparoscopic surgery was 9 days (range, 3-41 days). The median surgery time was 200 minutes (range, 57-444 minutes), and estimated blood loss was 50 mL (range, 10-3,500 mL). The median time to soft diet was 4 days (range, 2-8 days) and possible length of stay (hypothetical length of stay according to the discharge criteria) was 7 days (range, 4-22 days). The median total number of lymph nodes harvested was 23 (range, 8-71) and loop ileostomy was performed in 2 patients (4%). Six patients (11%) developed postoperative complications: 2 patients with anastomotic leakages, 1 with bladder leakage, and 3 with ileus. There was no mortality within 30 days.

CONCLUSION:

The present study shows that the presence of a SEMS does not compromise the laparoscopic approach. Laparoscopic resection following stent insertion for obstructing left-sided colon cancer could be performed with a favorable safety profile and short-term outcome. Large-scale comparative studies with long-term follow-up are needed to demonstrate a significant benefit of this approach.
