چکیده
Background: Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) was introduced into bariatric surgery by Sanchez-Pernaute et al. as an advancement of the biliopancreatic diversion with duodenal switch. Aim: To evaluate the SADI-S procedure with regard to weight loss, comorbidity resolution, and complication rate in the super obese population. Methods: A retrospective chart review was performed on initial 72 patients who underwent laparoscopic or robot-assisted laparoscopic SADI-S between December 17th, 2013 and July 29th, 2015. Results: A total of 48 female and 21 male patients were included with a mean age of 42.4±10.0 years (range, 22-67). The mean body mass index (BMI) at the time of procedure was 58.4±8.3 kg/m2 (range, 42.3-91.8). Mean length of hospital stay was 4.3±2.6 days (range, 3-24). Thirty-day readmission rate was 4.3% (n=3), due to tachycardia (n=1), deep venous thrombosis (n=1), and viral gastroenteritis (n=1). Thirty-day reoperation rate was 5.8% (n=4) for perforation of the small bowel (n=1), leakage (n=1), duodenal stump leakage (n=1), and diagnostic laparoscopy (n=1). Percentage of excess weight loss (%EWL) was 28.5±8.8 % (range, 13.3-45.0) at three months (n=28), 41.7±11.1 % (range, 19.6-69.6) at six months (n=50), and 61.6±12.0 % (range, 40.1-91.2) at 12 months (n=23) after the procedure. A total of 18 patients (26.1%) presented with type II diabetes mellitus at the time of surgery. Of these patients, 9 (50.0%) had their diabetes resolved, and six (33.3%) had it improved by 6-12 months after SADI-S. Conclusions: SADI-S is a feasible operation with a promising weight loss and diabetes resolution in the super-obese population. Racional: Anastomose única em bypass duodenoileal com gastrectomia vertical (SADI-S) foi introduzida na cirurgia bariátrica por Sanchez-Pernaute et al. como um avanço da derivação biliopancreática com switch duodenal. Objetivo: Avaliar o procedimento SADI-S no que diz respeito à perda de peso, resolução de comorbidades e taxa de complicações na população de superobesos. Métodos: Estudo retrospectivo com 72 pacientes iniciais que foram submetidos à laparoscopia ou por robô-assistida SADI-S laparoscópica entre 17 de dezembro de 2013 e 29 de Julho de 2015. Resultados: Foram incluídos 48 pacientes do sexo feminino e 21 do masculino com média idade de 42,4±10,0 anos (variação, 22-67). O índice de massa corporal (IMC) no momento do procedimento foi de 58,4±8,3 kg/m2 (42,3-91,8). O tempo médio de permanência hospitalar foi de 4,3±2,6 dias (3-24). A taxa de readmissão em 30 dias foi de 4,3% (n=3), devido à taquicardia (n=1), trombose venosa profunda (n=1), e gastroenterite viral (n=1). A taxa de reoperação em 30 dias foi de 5,8% (n=4) para a perfuração do intestino delgado (n=1), fístula (n=1), deiscência do coto duodenal (n=1), e laparoscopia de diagnóstico (n=1). Percentagem de excesso de perda de peso (% PEP) foi de 28,5±8,8% (13,3-45,0) em três meses (n=28), 41,7±11,1% (19,6-69,6) em seis meses (n=50), e 61,6±12,0% (40,1-91,2) aos 12 meses (n=23) após o procedimento. Um total de 18 pacientes (26,1%) apresentou-se com diabete melito tipo 2, no momento da operação. Desses, nove (50,0%) tiveram seu diabete resolvido, e seis (33,3%) tinham melhorado em 6-12 meses após SADI-S. Conclusões: SADI-S é operação viável com promissora perda de peso e de resolução do diabete melito na população de superobesos.

/10.10 15 A mmo ence: outh, nielco Loop duodenal switch (LDS) is a new surgical technique that allows surgeons to perform a duodenal switch with less effort and fewer complications [1]. Although Torres describes the potential for internal hernias (IHs) that may accompany the procedure, his study never found evidence of hernias. Single anastomotic techniques, LDS, and mini gastric bypass have ne...

Background: : Radiotherapy is an important factor which results in increase of anastomosis leakage. Diverting loop ileostomy has been usually performed after colorectal anastomosis with history of neo-adjuvant radiotherapy to decrease the chance of leakage. Considering this effect, we assessed the feasibility and outcome of human amniotic membrane in rectal anastomosis in dogs previously treate...
