Initiation and progression of physical activity after laparoscopic and open gastric bypass surgery.
This study compared postoperative physical activity participation among patients who underwent laparoscopic (LGBS) or open gastric bypass surgery (OGBS). Postoperative physical activity participation is considered important for achieving optimal weight loss and maintenance after gastric bypass surgery. However, no study has examined the relationship between surgery type and postoperative physical activity. Minimal invasiveness and reduced recovery time associated with LGBS compared with OGBS may permit earlier initiation and faster progression of postsurgical physical activity and potentially contribute to greater long-term adherence rates. Self-reported physical activity participation and aerobic physical activity hours per week at 2-weeks, 3-months, and 6-months postsurgery were assessed among LGBS and OGBS patients (presurgical body mass index of 35 to 70 kg/m(2)) at a university hospital from 1988-2002. Of the 2,235 patients, 531 (24%) and 1704 (76%) underwent LGBS and OGBS, respectively. A greater proportion of LGBS patients reported physical activity participation at each time point compared with OGBS patients (2 week, 76% vs 62%; 3 months, 84% vs 74%; 6 months, 85% vs 76%). Furthermore, LGBS patients reported a significantly greater physical activity duration at 2-weeks postsurgery compared with OGBS patients. A nonsignificant trend toward greater physical activity duration was observed in the LGBS patients at 3 months, whereas 6-month physical activity duration was similar between groups. LGBS, compared with OGBS, may promote earlier onset, progression, and maintenance of physical activity until 6 months postsurgery. Future studies need to prospectively determine whether LGBS, via facilitation of greater engagement in postsurgical physical activity, contributes to more successful weight loss and weight maintenance compared with OGBS.
