Introduction: The efficacy and safety of bariatric surgery (BS) are well documented, but data in our region is lacking.

Aim: Analyze the long term effect of BS on obese patients in a single district hospital. Primary outcomes: –weight change 5–10 years post BS; –patient satisfaction. Secondary outcomes: weight reduction according to type of surgical procedure, sex, public/private hospital; mortality, complications.

Materials and methods: Retrospective data collection from electronic patients record and telephone calls to patients. Study group: all patients undergoing BS before 2015. Control group: 40 obesity patients not treated with BS. Weight data collected for 5–10 years expressed as median of all available weights for each year post-op/post-entry.

Results: 58 BS patients (61 procedures); 40 patients not operated. Gastric bypass (GB) 44 procedures, vertical banded gastroplasty (VBG) 7, sleeve gastrectomy (SG) 7, Scopinaro 2, adjustable gastric banding (AGB) 1. Re-operations: 3 VBG to GB, 1 SG to GB. 1 AGB removed year 2 (technical malfunction). Public procedures 88% (Hospital Universitario Donostia), Private 11% (elsewhere).

Long term weight change: Median weight 5 and 10 years post BS: 70% and 74% of pre-OP weight. Control group (no BS): 98% and 103% of initial weight. 68% of BS achieved 20% weight loss at 10 years; 39% achieved 30%. None of control group patients did. Failed operations (defined as 10-year weight loss <5%): 1 VBG patient (3%).

Patient satisfaction: Defined as not regretting having undergone BS. Data collection 67%. 37 patients (94%) did not regret their decision. 1 patient unsatisfied due to refractory hypoglycemia; 1 patient unsure. Weight change according to type of procedure, sex, public/private hospital No major differences apparent (graphs on poster).

Mortality: One death identified: over 10 years after BS, cause of death considered unrelated.

Complications: Defined as any hospital admission within 2 years of BS.

Data collection 66%: 33% of BS followed by hospital admission within 2 years: most considered ‘mild’, 3 (7%) considered ‘serious’: 2 bowel perforations requiring laparotomy, 1 Petersen´s space hernia requiring laparotomy. Favorable outcomes.

Limitations: Gaps in data collection as loss of follow-up common, reliability of data on occasions questionable as obtained by telephone calls to patients; unable to exclude unidentified deaths as patients operated as early as 1997.

Conclusion: BS is effective long term in our patients. Our results are comparable to those shown elsewhere in the literature.
