Background
The aim of this study was to determine whether mobilization of the splenic flexure during anterior resection is associated with an increased number of complications.
Methods
This is a retrospective cohort analysis of all non-emergent anterior resections with anastomosis (open and laparoscopic) between January 2005 and December 2009 from the American College of Surgeons National Surgical Quality Improvement Program. Infectious, renal, and pulmonary adverse events as well as operative times were analyzed for cases with splenic flexure mobilization as compared to no mobilization. We then constructed multivariate models to identify risk factors for postsurgical adverse events.
Results
During the 5-year study period, 6,324 (57 %) open resections and 4,788 (43 %) laparoscopic resections were performed. Mobilization of the splenic flexure was associated with an increase in operating room time (204 vs 172 min, p < 0.0001). Although anastomotic leaks were not recorded, there was no difference in organ space infections (3.9 vs 3.7 %, p = 0.7) or return to operating room events between the two groups. However, patients who underwent splenic flexure mobilization had significantly more superficial surgical site infections (10.6 vs 8.4 %, p < 0.0002). Multivariate analysis accounting for laparoscopic or open surgery and standard preoperative and intraoperative variables demonstrated a persistent increase in superficial surgical site infections for patients with splenic flexure mobilization.
Conclusions
Operating room times are longer and superficial surgical site infections are more common when the splenic flexure is mobilized. The absolute indications for splenic flexure mobilization should be addressed in further research.
