COMPLICATIONS AND LATE FOLLOW-UP OF SCOPINARO’S SURGERY WITH GASTRIC PRESERVATION: 1570 PATIENTS OPERATED IN 20 YEARS

ABSTRACT - BACKGROUND: Scopinaro-type biliopancreatic diversion (BPD-S) and its variations are the surgeries that offer the best immediate results in weight loss and regain in the late follow-up. It has a high rate of immediate complications and demands control with frequent laboratory tests. AIMS: The aim of this study was to analyze the late postoperative complications of 1570 patients operated by biliopancreatic diversion with gastric preservation laparoscopic video with up to 20 years of postoperative follow-up. METHODS: In a follow-up period of up to 20 years, the clinical and surgical complications of 1570 patients with grade II or III obesity were evaluated who were operated on from 2001 to 2014 with the same team of surgeons. Clavien Dindo 11 classification was used for analysis and comparison. Laboratory tests and body mass index (BMI) were used in the analysis of late metabolic outcomes. RESULTS: On the one hand, complications in 204 patients were recorded (13%), and 143 patients (9.1%) were reoperated. On the other hand, 61 patients (29.9%), who had postoperative complications were clinically treated with good evolution in 9.2 years (95%CI 8.2-10.3), with a median of 9.5 years (95%CI 6.1-12.9). Gastroileal anastomosis ulcers occurred in 44 patients (2.8%). Patients with malnutrition, severe anemia, or chronic diarrhea were operated on with common loop elongation (n=64 - 4%), conversion to gastric diversion (n=29 - 5%), or reversal of surgery (n=10 - 0.6%). One death was registered throughout casuistry (0.06%). CONCLUSIONS: Metabolic result of DBP-S was considered excellent in most patients, even referring to changes in the frequency of bowel movements, loose stools, and unpleasant odor. Complications are usually serious and most of the patients require surgical treatment. Therefore, the biliopancreatic diversion of Scopinaro should be reserved for exceptional cases, as there are safer surgical alternatives with less serious side effects. RESUMO - RACIONAL - A derivação biliopancreática tipo Scopinaro (DBP-S) e suas variações são as cirurgias que oferecem os melhores resultados imediatos na perda de peso e de reganho de peso no acompanhamento tardio. Apresenta índice elevado de complicações imediatas e demanda controle laboratorial frequente. OBJETIVOS - Analisar as complicações pós-operatórias tardias de 1.570 pacientes operados por derivação biliopancreática com preservação gástrica videolaparoscópica com até 20 anos de acompanhamento pós-opera
