Impact of Three-Dimensional Laparoscopy in a Bariatric Surgery Program: Influence in the Learning Curve.

INTRODUCTION: 3D laparoscopy allows the surgeon to regain the sense of depth and improve accuracy. The aim of the study was to assess the impact of 3D in bariatric surgery. PATIENTS AND METHODS: A retrospective cohort study was conducted. All our patients who underwent bariatric surgery (sleeve gastrectomy (SG) or gastric bypass (GB)) between 2013 and 2016 were included. We compared 3D laparoscopy cohort and 2D laparoscopy cohort. Variables are as follows: age, sex, DM, hypertension, surgeon experience, and type of intervention. Comparisons of operative time, hospital stay, conversion, complications, reoperation, and exitus are completed. RESULTS: Three hundred twelve consecutive patients were included. 56.9% of patients underwent GB and 43.1% SG. Global complications were 3.2% (fistula 2.5%, hemoperitoneum 0.3%, others 0.4%). One hundred four procedures were performed in the 3D cohort and 208 in the 2D cohort. The 2D cohort and 3D cohort were similar regarding the following: percentage of GB vs SG, age, gender, learning curve, diabetes mellitus 2, hypertension, and sleep apnea. The operating time and hospital stay were significantly reduced in the 3D cohort (144.07 ± 58.07 vs 172.11 ± 76.11 min and 5.12 ± 9.6 vs 7.7 ± 13.2 days. It was the same when we stratified the sample by type of surgery or experience of the surgeon. Complications were reduced in the 3D cohort in the surgeries performed by novice surgeons (10.2 vs 1.8%, p = 0.034). CONCLUSIONS: The use of 3D laparoscopy in bariatric surgery in our center has helped reducing the operating time and hospital stay, and improving the safety of the surgery, either in GB or SG, being equally favorable in novice or more experienced surgeons.

Pancreatectomía central en el tratamiento de lesión pancreática benigna. Presentación de un caso y revisión de la literatura / Central pancreatectomy for the treatment of a benign pancreatic lesion. Case report and literature review

Presentamos el caso de una mujer de 45 años diagnosticada incidentalmente de lesión quística pancreática compatible con cistoadenoma seroso de 14 mm. Tras cinco años de seguimiento (TAC y RM) la lesión triplicó su tamaño y se indicó la intervención. Teniendo en cuenta la probable benignidad de la lesión, y en un intento de preservar tanto el bazo como la mayor cantidad posible de parénquima pancreático, se realizó una pancreatectomía central con derivación del remanente distal. Se revisa la literatura nacional e internacional publicada (AU)

We present the case of a 45 year old female patient with an incidental diagnosis of a cystic pancreatic lesion corresponding to a serous cystadenoma of 14 mm. During a 5-year follow-up (CT and MRT) the lesion tripled in size and a surgical intervention was decided upon. The lesion was thought to have a benign pathology and, in an attempt to preserve the spleen and a major portion of pancreatic tissue, a central pancreatectomy with a diversion of the remaining distal pancreas was carried out. The authors reviewed national and international publications (AU)

First case reported of Bouveret´s syndrome associated to duodenal and biliary perforation to retroperitoneum.

We present the case of a 69 year old woman with a history of cholecystitis, who consulted for severe abdominal pain, nausea and vomiting. Abdominal CT showed duodenal obstruction caused by a gallstone, cholecystoduodenal fistula and pneumobilia, what is known as Bouveret's syndrome, a rare form of gallstone ileus. Additionally, she presented free duodenal and vesicular perforation to retroperitoneum at the same level of the cholecystoduodenal transit point. The patient underwent a difficult cholecystectomy, enterolithotomy, repair of the duodenal defect, extensive washing and drainage of the retroperitoneum. The postoperative course was uneventful except for a laparotomy infection.

Primer caso publicado de síndrome de Bouveret asociado a perforación duodenal y vesicular al retroperitoneo / First case reported of Bouveret´s syndrome associated to duodenal and biliary perforation to retroperitoneum

Presentamos el caso de una mujer de 69 años con diagnóstico de colelitiasis, que acudió a urgencias por cuadro de dolor abdominal intenso, náuseas y vómitos. Un TAC abdominal mostró obstrucción duodenal causada por cálculo biliar de 4 cm, fístula colecistoduodenal y neumobilia, lo que en conjunto se conoce como síndrome de Bouveret, una forma rara de íleo biliar. Adicionalmente presentaba perforación duodenal y vesicular libre a retroperitoneo en el mismo punto de tránsito colecistoduodenal. La paciente fue intervenida quirúrgicamente, realizando colecistectomía dificultosa, enterolitotomía, reparación del defecto duodenal, lavado exhaustivo y drenaje del retroperitoneo. El postoperatorio transcurrió sin complicaciones salvo infección de la herida quirúrgica (AU)
