Comparison of iatrogenic splenectomy during open and laparoscopic colon resection

Iatrogenic splenic injury requiring splenectomy is a well-recognized and potentially serious complication of colon resection. Iatrogenic splenectomy is associated with significant morbidity and mortality, including bleeding and the postsplenectomy sepsis syndrome. Our study aims to compare the incidence of iatrogenic splenectomy in laparoscopic colon resection with that of open colon resection over an 11-year-period at Mount Sinai. A retrospective chart review of all patients undergoing colon resection at Mount Sinai Medical Center during the last 11 years was performed to identify patient demographics, procedure, indication, and outcome. There was a significant difference (P=0.03) in the incidence of iatrogenic splenectomy during open colectomy (13/5477, 0.24%) versus laparoscopic colectomy (0/1911, 0%). All cases complicated by iatrogenic splenectomy involved splenic flexure mobilization. Laparoscopy has many recognized advantages over open procedures, including shorter recovery and length of stay. This retrospective review of our experience at Mount Sinai presents another potential benefit of the laparoscopic approach to colon resection.
