BACKGROUND: Laparoscopic gastric bypass (GBP) is becoming a common approach for treatment of morbid obesity. We analyzed preoperative factors that may be associated with operative outcomes in laparoscopic GBP. STUDY DESIGN: This prospective study evaluates 150 consecutive laparoscopic GBP procedures performed by a single surgeon. Preoperative factors were grouped into three categories: 1) patient-specific (gender, age, abdominal surgical history, smoking), 2) obesity-specific (body mass index, hypertension, diabetes, sleep apnea), and 3) procedure-specific (operative experience of the surgeon [75 cases or less versus more than 75 cases]). Length of operation (240 minutes or less versus more than 240 minutes), postoperative complications (yes versus no), major complications (yes versus no), reoperation (yes versus no), and length of hospital stay (4 days or less versus more than 4 days) were the operative outcomes considered. In this series all patients who had a major complication required a reoperation. Data were analyzed using univariate and multiple logistic regression analyses. RESULTS: Operative experience of surgeon (75 cases or less) was associated with lengthy operative time (adjusted odds ratio [AOR], 3.8; 95% confidence interval [CI], 1.7 to 8.3), major complications (AOR, 15.0; 95% CI, 1.5 to 143.0), and a lengthy (more than 4 days) hospital stay (AOR, 4.5; 95% CI, 1.1 to 18.0). Higher patient age (50 years or more) was associated with more postoperative complications (AOR, 11.4; 95% CI, 3.0 to 43.1) and major complications (AOR, 7.6; 95% CI, 1.1 to 48.7). Male gender also was associated with more postoperative complications (AOR 5.2; 95% CI, 1.1 to 23.1). Obesity-related comorbidities, body mass index, past abdominal surgical history, and smoking had no statistical association with operative outcomes in this study. CONCLUSIONS: There is an association of clinical outcomes after laparoscopic GBP with the age and gender of the patient and the operative experience of the surgeon. An operative experience of more than 75 laparoscopic GBP cases was associated with decreases in operative time, length of hospital stay, and number of major complications.
