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)

Neuroendocrine tumor of the pancreas in a patient with tuberous sclerosis: a case report and review of the literature.

A rare case of pancreatic neuroendocrine neoplasm in a patient with tuberous sclerosis complex is described. The patient was a 31-year-old man who had multiple congenital subependymal nodules, bilateral cortical tubers, and seizures of difficult control. A 2.3 cm × 2 cm well-delimitated solid tumor in the tail of the pancreas was discovered during a monitoring abdominal computed tomography. A distal pancreatectomy was performed. Histologically, the tumor was formed by uniform cells with moderated cytoplasm arranged in a combined trabecular and nested pattern. The nuclear features were bland, and mitosis was infrequent. There was no vascular invasion. Immunoreactivity for cytokeratine AE1/AE3, chromogranin A, and synaptophysin confirmed the neuroendocrine nature of this neoplasia. Pancreatic hormones were negatives. One of the 5 lymph nodes isolated from the peripancreatic adipose tissue was positive for metastases. Small series and case reports have documented that in tuberous sclerosis many endocrine system alterations might occur, affecting the function of the pituitary, parathyroid, and other neuroendocrine tissue, including islet cells of the pancreas. However, the true association of these pathological conditions remains uncertain. As far as we know, there are 10 cases reported of pancreatic neuroendocrine tumors in a setting of tuberous sclerosis complex, in which 2 cases resulted in malignant, nonfunctioning pancreatic neuroendocrine tumors.

The influence of immunosuppression switching in liver function in adult hepatic transplantation.

We evaluate the 5-year results of a single-centre prospective randomized trial that compared cyclosporine microemulsion (CyA-me) in triple therapy (plus steroids and azathioprine) and Tacrolimus (Tac) in double therapy (plus steroids) for primary immunosuppression. One hundred adult patients undergoing liver transplantation were randomized to receive Tac (n=51) or CyA-me (n=49). Ten patients in group A, and thirty-one patients in group B had their main immunosuppressive agent switched. The switch was much more frequent from CyA-me to Tac (n=31; 62.3%), mainly because of lack of efficacy (n=12; 38.7%). Six of 10 patients were shifted from Tac to CyA-me for side effects. The clinical course of the majority of patients converted from CyA-me to Tac improved clearly after conversion. Donor age and acute rejection (number, severity and rejection free days) had a significative association with lack of efficacy in group B. In these series, the conversion to Tac from CyA-me could be accomplished safely, with an excellent long-term outcome.
