BackgroundThe 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.MethodsWe 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.ResultsAverage 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.ConclusionsOur 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.
