BACKGROUND: The 2 weight loss procedures most commonly performed in the United States are Roux-en-Y gastric bypass (RYGBP) and lateral gastrectomy with duodenal switch (BPD/DS). RYGB is a restrictive procedure, whereas BPD/DS relies on mild restriction of intake as well as malabsorption. Many physicians believe that weight loss is greater after BPD/DS than after RYGBP. However, these procedures have not been compared using groups of patients operated on by the same surgeons at the same institution. METHODS: We compared weight loss (expressed as percent of excess body weight [%EBW]) after 1 and 2 years in patients who underwent open RYGB or BPD/DS at our institution. RESULTS: Average length of stay was longer in BPD/DS patients than in those undergoing RYGBP (8.7 vs. 5.9 days, P <0.05). Anastomotic leaks were higher after BPD/DS (6% vs. 3%), but the difference did not achieve statistical significance. Mortality did not differ between the 2 groups (0.8% vs. 0.9%). In the group of patients followed-up for 1 to 2 years, age and distribution of men and women did not differ. Those patients undergoing BPD/DS had higher body mass index (59 vs. 55, P <0.05). Weight loss expressed as %EBW was similar between the 2 groups: 54% versus 53% at 1 year and 67% versus 64% at 2 years. CONCLUSIONS: Our data suggested that weight loss expressed as %EBW is similar between patients undergoing RYGBP and those undergoing BPD/DS. However, BPD/DS was associated with a longer hospital stay.
