Objective: To determine the mid- and long-term efficacy and possible side effects of laparoscopic sleeve gastrectomy as treatment for morbid obesity.

Summary Background Data: Laparoscopic sleeve gastrectomy is still controversial as single and final treatment for morbid obesity. Some favorable short-term results have been published, however long-term results are still lacking.

Methods: In the period between November 2001 and October 2002, 53 consecutive morbidly obese patients who, according to our personal algorithm, were qualified for restrictive surgery were selected for laparoscopic sleeve gastrectomy. Of the 53 patients, 11 received an additional malabsorptive procedure at a later stage because of weight regain. The percentage of excess weight loss (EWL) was assessed at 3 and 6 years postoperatively. A retrospective review of a prospectively collected database was performed for evaluation after 3 years. Recently, after the sixth postoperative year, patients were again contacted and invited to fill out a questionnaire.

Results: Full cooperation was obtained in 41 patients, a response rate of 78%. Although after 3 years a mean EWL of 72.8% was documented, after 6 years EWL had dropped to 57.3%, which according to the Reinhold criteria is still satisfactory. These results included 11 patients who had benefited from an additional malabsorptive procedure (duodenal switch) and 2 patients who underwent a “resleeve” between the third and sixth postoperative year. Analyzing the results of the subgroup of 30 patients receiving only sleeve gastrectomy, we found a 3-year %EWL of 77.5% and 6+ year %EWL of 53.3%. The differences between the third and sixth postoperative year were statistically significant in both groups. Concerning long-term quality of life patient acceptance stayed good after 6 + years despite the fact that late, new gastro-esophageal reflux complaints appeared in 21% of patients.

Conclusions: In this long-term report of laparoscopic sleeve gastrectomy, it appears that after 6+ years the mean excess weight loss exceeds 50%. However, weight regain and de novo gastroesophageal reflux symptoms appear between the third and the sixth postoperative year. This unfavorable evolution might have been prevented in some patients by continued follow-up office visits beyond the third year. Patient acceptance remains good after 6+ years.

In this long-term follow-up study of laparoscopic sleeve gastrectomy for morbid obesity, it appears that patients experience weight regain between the third and the sixth postoperative year. Remaining weight loss after 6+ years is still acceptable. Gastroesophageal reflux symptoms are a frequent complaint. Patient acceptance is good.
