BACKGROUND: Limiting surgical morbidity while maintaining staging adequacy is a primary concern in obese patients with uterine malignancy. The goal of this study was to compare the surgical adequacy and postoperative morbidity of three surgical approaches to staging the disease of obese women with uterine cancer. METHODS: The records of all patients with a body mass index (BMI) of >or=35 undergoing primary surgery for uterine corpus cancer at our institution from January 1993 to May 2006 were reviewed. Patients were assigned to three groups on the basis of planned surgical approach-standard laparotomy, laparoscopy, or laparotomy with panniculectomy. Standard statistical tests appropriate to group size were used to compare the three groups. RESULTS: In all, 206 patients with a BMI of >or=35 were grouped as follows: laparotomy, 154 patients; laparoscopy, 25 patients; and laparotomy with panniculectomy, 27 patients. Median BMI was 41 (range, 35-84). Regional lymph nodes were removed in 45% of the laparotomy patients, 40% of the laparoscopy patients, and 70% of the panniculectomy patients (P = .04). Compared with laparotomy, both laparoscopy and panniculectomy yielded higher median pelvic and total lymph node counts (P = .001). Operative time was shortest after standard laparotomy, and blood loss was greatest after panniculectomy. The incidence of all incisional complications was lower for panniculectomy (11%) and laparoscopy (8%) compared with standard laparotomy (35%) (P = .002). On multivariate analysis, a significantly lower risk of total incisional complications was seen for patients undergoing panniculectomy (risk ratio, .25; 95% confidence interval, .071-.88) and laparoscopy (risk ratio, .19; 95% confidence interval, .04-.94). CONCLUSIONS: Both laparoscopic staging and panniculectomy in a standardized fashion were associated with an improved lymph node count and a lower rate of incisional complications than laparotomy alone. Although definitive conclusions are limited by low patient numbers, the substantial decrease in wound complications suggests that these two approaches should be considered for obese patients undergoing uterine cancer staging.
