Sadi-s with Right Gastric Artery Ligation: Technical Systematization and Early Results
نویسندگان
چکیده
Background: Bariatric surgery is performed all over the world with close to 500.000 procedures per year. The most performed techniques are Roux-en-Y gastric bypass and sleeve gastrectomy. Despite this data, the most effective procedure, biliopancreatic diversion with or without duodenal switch, represents only no more than 1.5% of the procedures. Technical complexity, morbidity, mortality, and severe nutritional adverse effects related to the procedure are the main fears that prevent most universal acceptance. Aim: To explain the technical aspects and the benefits of the SADI-S with right gastric artery ligation as an effective simplification from the original duodenal switch. Methods: Were included all patients undergoing this procedure from the November 2014 to May 2016, describing and analysing aspects of this technique, the systematization and early complications associated with the procedure. Results: A series of 67 patients were operated; 46 were women (68.7%); mean age of the group was 44 years old (33-56); and an average BMI of 53.5 kg/m2 (50-63.5). Surgical time was 115 min (80-180). A total of five patients (7.5%) had any complication and two (2.9%) had to be reoperated. There were two patients with leak, one at the duodenal stump and other at the esophagogastric angle. There was no mortality. Patients stayed at the hospital a median of 2.5 days (1-25). Conclusions: SADI-S with right gastric artery ligation is a safe procedure with few preliminary complications. The technical variations introduced to the classical duodenal switch are reproducible and may allow this procedure to be more popular. All the complications in this series were not related to the ligation of the right gastric artery. Racional: Cerca de 500.000 cirurgias bariátricas são realizadas a cada ano em todo o mundo. As técnicas mais realizadas são o bypass gástrico em Y-de-Roux e a gastrectomia vertical. A derivação biliopancreática, com ou sem duodenal switch, é considerada técnica mais eficaz no tratamento cirúrgico do paciente obeso mórbido; entretanto, representa não mais do que 1,5% dos procedimentos na atualidade, pois sua complexidade técnica, morbimortalidade e graves efeitos adversos nutricionais impedem aceitação mais universal. Objetivo: Descrever os aspectos técnicos e os benefícios do SADI-S com ligadura da artéria gástrica direita como um modo simplificado do duodenal switch original. Métodos: Foram incluídos todos os pacientes submetidos a este procedimento entre novembro 2014 e maio de 2016. Além da descrição da sistematização da técnica operatória, foram analisadas as complicações precoces associadas ao procedimento. Resultados: Uma série de 67 pacientes foi operada no período analisado; 46 eram mulheres (68,7%) e a média de idade foi de 44 anos (33-56). O IMC médio foi de 53,5 kg/m2 (50-63,5). O tempo cirúrgico médio foi de 115 min (80-180) e a permanência hospitalar média foi de 2,5 dias (1-25). Complicações foram observadas em cinco pacientes (7,5%) e dois (2,9%) tiveram de ser reoperados. Duas pacientes evoluíram com fístula, uma no coto duodenal e outra na junção esofagogástrica. Não houve mortalidade. Conclusão: SADI-S com ligadura da artéria gástrica direita é procedimento seguro com poucas complicações precoces. A simplificação técnica em relação ao duodenal switch clássico pode permitir que este procedimento se torne mais popular. Todas as complicações observadas nesta série não estavam relacionadas com a ligadura da artéria gástrica direita.

In the present study was performed to evaluate the follicular growth and hormonal changes after ovarian artery ligation in rats. Fifty six virgin 90-day–old female rats were used. The rats were chosen from 100 female rats by a vaginal smear, which showed that they were synchronized in estrous phase of the menstrual cycle. Animals were kept in seven cages (n=8 in each) at a temperature of 22 ± 2...

متن کاملLaparoscopic ischaemic conditioning of the stomach may reduce gastric-conduit morbidity following total minimally invasive oesophagectomy.
OBJECTIVE Oesophagectomy, whether open or minimal access, is associated with a significant incidence of gastric-conduit-related complications. Previous animal and human studies suggest that ischaemic conditioning of the stomach prior to oesophagectomy improves perfusion of the gastric conduit. We have adopted laparoscopic ligation of the left gastric artery 2 weeks prior to minimally invasive o...
