Long-term outcomes of morbidly obese patients treated with gastrogastrostomy.

Long-term outcomes in 123 morbidly obese patients who had undergone gastrogastrostomy were studied to determine weight losses 19 to 47 months after surgery. Follow-up data were available for 84% (103) of the patients. Overall, 58% of these (60 of 103) had maintained losses of greater than or equal to 30% excess weight. Using a best case/worst case analysis, between 49% and 65% of patients had achieved losses of greater than or equal to 30% excess weight. Six patients had gained weight. Eighty-seven per cent of the patients reported increased or stable energy levels; job status was stable or improved for 95%; and 20% had been rehospitalized. Use of antihypertensive medication and use of insulin had decreased. Over two thirds (69%) of the patients stated they would recommend gastrogastrostomy to a friend, and 54% were either very satisfied or satisfied with the operation. Energy level and degree of satisfaction were related to amount of weight lost. Gastrogastrostomy achieved long-term moderate weight losses in three fifths of morbidly obese patients, without causing serious adverse health outcomes.
