BACKGROUND: Previous studies have compared open versus hand-assisted and open versus total laparoscopic Roux-en-Y gastric bypass. This study compared hand-assisted and total laparoscopic Roux-en-Y gastric bypass surgery performed at 2 institutions by 2 surgeons, each specializing in 1 of the techniques. METHODS: Gastric bypass operations (n = 272) were evaluated from January 1, 2004 to December 31, 2004. The comparisons between the hand-assisted (n = 149) and laparoscopic (n = 123) approach were done using the median test, t test, chi-square analysis, and Fisher's exact test. RESULTS: The average patient age was 43.9 years, and 84% (229 of 272) of the patients were women. The average body mass index was 48.8 kg/m2. No significant difference was found between the hand-assist and laparoscopic groups in age, gender, preoperative body mass index, diabetes, hypertension, or operative time. No significant difference was found in the mortality rate between the hand-assist (2 of 149, 1.3%) and laparoscopic (1 of 123, 0.8%) groups. Also, no significant difference was found in the incidence of leaks, pulmonary embolism, deep venous thrombosis, wound infection, bowel obstruction, incisional hernia, fistula, persistent vomiting, or reoperation between the 2 procedures. A significant difference was found in the length of stay, with a median of 3 days for the hand-assist group and 2 days for the laparoscopic group (P <.001), and hemorrhage requiring transfusion, which occurred in 1 (.7%) of 149 hand-assist patients and 7 (5.7%) of 123 laparoscopic patients (P = .025). The percentage of excess weight loss 6 months after surgery was also similar between the two groups, at 50.2% and 52.1% for the hand-assist and laparoscopic groups, respectively (P = .45). CONCLUSIONS: The results of this study have found that both hand-assist and laparoscopic Roux-en-Y gastric bypass can be accomplished with similar perioperative risks and outcomes, including weight reduction. The choice between the 2 procedures depends on surgeon preference.
