Objective Colorectal surgeons often struggle to explain to administrators/payers reasons for prolonged length of stay (LOS). This study aim was to identify factors associated with increased LOS after colorectal surgery. Design The study population included patients from the 2007 American-College-of-Sur- geons-National-Surgical-Quality-Improvement-Program (ACS-NSQIP) database undergoing ileocolic resection, segmental colectomy, or anterior resection. The study population was divided into normal (below 75th percentile) and prolonged LOS (above the 75th percentile). A multivariate analysis was performed using prolonged LOS as dependent variable and ACS- NSQIP variables as predictive variables. P-value < 0.01 was considered significant. Results 12,269 patients with a median LOS of 6 (inter-quartile range 4-9) days were includ- ed. There were 2,617 (21.3%) patients with prolonged LOS (median 15 days, inter-quartile range 13-22). 1,308 (50%) were female, and the median age was 69 (inter-quartile range 57-79) years. Risk factors for prolonged LOS were male gender, congestive heart failure, weight loss, Crohn's disease, preoperative albumin < 3.5 g/dL and hematocrit < 47%, base- line sepsis, ASA class ≥ 3, open surgery, surgical time ≥ 190 min, postoperative pneumonia, failure to wean from mechanical ventilation, deep venous thrombosis, urinary-tract in- fection, systemic sepsis, surgical site infection and reoperation within 30-days from the primary surgery. Conclusion Multiple factors are associated with increased LOS after colorectal surgery. Our results are useful for surgeons to explain prolonged LOS to administrators/payers who are critical of this metric.

Objective Laparoscopic approach should be offered for most patients requiring colectomy, as it is a safe procedure, associated with shorter hospitalization, better cosmetic results, and does not affect negatively the oncological outcomes of patients with colon cancer. However, there is no consistent data on the safety of laparoscopic surgery training during residency. Therefore, the aim of this study was to assess whether or not the resident par- ticipation in laparoscopic colectomy affected the postoperative outcomes. Methods The database of the American College of Surgeons National Surgical Quality Im- provement Program (ACS-NSQIP) was searched for patients undergoing laparoscopic col- ectomies between 2005 and 2007. We excluded patients with no data regarding whether or not there was a resident participation in the operation. The study population was divided into 2 groups (resident and nonresident), according to residents participation in the surgi- cal procedure. Perioperative variables and postoperative complications were compared be- tween groups. A multivariate analysis was performed to evaluate the association between postoperative complications and resident participation in the operation. Results The search yielded 5,912 patients with a median age of 63 years. Of these, 3,112 (53%) were female and 3.887 (66%) had a resident involved in their operation. The resident group had a significantly longer mean operative time (163 ± 64 min vs 138 ± 58 min, p < 0.0001). Other variables did not differ significantly between groups. Moreover, multivari- ate analysis showed no association between resident participation and the occurrence of postoperative complications. Conclusion Laparoscopic training during residency may be safely performed without threatening the patient's integrity.
