RESUMEN
Abstract Purpose: To perform technically the laparoscopic sleeve gastrectomy (LSG) using a unique Intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique. Methods: IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy. Results: All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications. Conclusion: Intragastric Single Port is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.

ABSTRACT Objective : to test the minimally invasive technique of single-port transaxillary subtotal parathyroidectomy in non-formalized cadavers to evaluate its viability and reproduction. Method : we performed ten subtotal parathyroidectomies through a transaxillary TriPort access in cadavers. The technique consisted of access through the axillary fossa, creating a subcutaneous tunnel to the anterior cervical region, for handling of the thyroid gland and dissection and resection of the parathyroid glands. Results : all surgeries were successful. The mean time of surgery was 65 minutes (57-79 min), with uncomplicated identification of all anatomical structures. There was no need for complementary incisions in the cervical region. Conclusion : the transaxillary single-port subtotal parathyroidectomy technique was feasible and reproducible, suggesting an alternative for minimally invasive cervical surgery.
RESUMO Objetivo: testar a técnica minimamente invasiva de paratireoidectomia subtotal transaxilar single-port em cadáveres não formalizados para avaliar sua viabilidade e reprodução. Método: foram realizadas dez paratireoidectomias subtotais por via transaxilar através de acesso por TriPort em cadáveres. A técnica realizada consistiu em acesso pela fossa axilar, criando-se um túnel subcutâneo até a região cervical anterior, para manuseio da glândula tireoide e dissecção e ressecção das paratireoides. Resultados: todas as cirurgias foram realizadas com sucesso. O tempo médio de cirurgia foi 65 minutos (57-79 min), com identificação, sem dificuldades, de todas as estruturas anatômicas. Não houve necessidade de incisões complementares na região cervical. Conclusão: a técnica de paratireoidectomia subtotal transaxilar single-port foi viável e reprodutível, sugerindo uma alternativa para a cirurgia cervical minimamente invasiva.
