Necrosis intestinal, una complicación infrecuente de la nutrición enteral por yeyunostomía / Mesenteric necrosis, a rare complication of feeding jejunostomy

RESUMEN La nutrición enteral es parte importante del soporte vital avanzado en el paciente crítico, y ha demostrado ser más fisiológica, económica y con resultados superiores a la nutrición parenteral. La yeyunostomía para alimentación enteral está indicada cuando no es posible la alimentación por vía oral y está contraindicada la utilización de una sonda nasogástrica o nasoyeyunal de alimentación. Es una vía de alimentación con escasa morbilidad, aunque no está exenta de complicaciones, y algunas de ellas pueden ser graves. Comunicamos un caso de necrosis intestinal vinculado a la alimentación enteral por yeyunostomía en un paciente sometido a una gastrectomía oncológica.

ABSTRACT Enteral nutrition is an important component of advanced life support in the critically ill patient, and has demonstrated to be more physiologic, cheaper and with better results than parenteral nutrition. Jejunostomy for enteral nutrition is indicated when the oral route is impossible and the use of a nasogastric or nasojejunal feeding tube is contraindicated. Although the rate of complications associated with enteral nutrition through jejunostomy is low, they may occur and be serious. We report a case of bowel necrosis associated with a jejunostomy performed for enteral nutrition in a patient who underwent oncologic gastrectomy.

Duodenectomía parcial distal con conservación del páncreas por un tumor del estroma gastrointestinal / Distal partial duodenoscopy with pancreas conservation for stromal gastrointestinal tumor

Los tumores del estroma gastrointestinal son los tumores mesenquimatosos más frecuentes del sistema digestivo. En el duodeno son raros, con menos de 5 por ciento. A diferencia de los carcinomas, los tumores del estroma gastrointestinal no infiltran la mucosa de manera extensa. La resección quirúrgica con bordes de sección negativos sin linfadenectomía es el principal tratamiento con intención curativa y las resecciones conservadoras se llevan a cabo siempre y cuando sean factibles desde el punto de vista técnico. Presentamos una paciente con un tumor del estroma gastrointestinal de duodeno cuya principal manifestación fue el sangrado digestivo alto. La lesión fue resecada con bordes de sección quirúrgicos negativos mediante una duodenectomía parcial distal de la tercera y cuarta porciones del duodeno con preservación del páncreas. El tránsito intestinal fue restituido mediante una duodenoyeyunostomía término-terminal en un plano de sutura. En este momento, la paciente recibe tratamiento con metisilato de imatinib(AU)

Gastrointestinal stromal tumors are the most frequent mesenchymal tumors of the digestive system. In the duodenum, their presentation is rare, with less than 5 persent. Unlike carcinomas, gastrointestinal stromal tumors do not extensively infiltrate the mucosa. Surgical resection with negative section borders without lymphadenectomy is the main treatment with curative intent, and conservative resections are carried out as long as they are feasible from the technical point of view. We present the case of a patient with a gastrointestinal stromal tumor of the duodenum and whose main manifestation was high digestive bleeding. The lesion was resected with negative surgical section borders through a distal partial duodenectomy of the third and fourth portions of the duodenum and with preservation of the pancreas. The intestinal transit was restored by a terminal duodenojejunostomy in a suture plane. At this time, the patient is treated with imatinib mesylate(AU)

Divertículo epifrénico / Epinephrine diverticulum

El divertículo epifrénico provocado por el aumento de la presión intraesofágica a causa de alteraciones motoras subyacentes es raro; representa cerca del 10 por ciento de todos los divertículos esofágicos. Se presenta el caso de una paciente de 65 años de edad, que ingresó en el Servicio de Cirugía General con ictericia obstructiva por pancreatitis crónica. Se le realizó una triple derivación de Catell y durante la evolución posoperatoria comenzó a presentar vómitos que contenían alimentos sin digerir, fétidos, ingeridos con horas o días de antelación. Se le realizó una radiografía baritada de esófago, estómago y duodeno, con buen pase de contraste al duodeno, y se observó la presencia de un divertículo epifrénico de gran tamaño, responsable de los síntomas. Fue intervenida quirúrgicamente utilizando como vía de acceso una incisión media previa y vía transhiatal. Se practicó una vagotomía, diverticulectomía, miotomía esofágica extendida, procedimiento antirreflujo y yeyunostomía temporal para la alimentación precoz. La evolución fue favorable y la paciente está hoy asintomática(AU)

The epinephrine diverticulum due to the increase of intraesophageal pressure by underlying motor alterations is a rare entity; it accounts for around the 10% of all esophageal diverticula. This is the case of a female patient aged 65 admitted in the General Surgery Service presenting with obstructive jaundice by chronic pancreatitis. A triple Catell's bypass was carried out and during the postoperative course had vomiting containing non-digested fetid foods, ingested many hours or days ago. Barium radiography of esophagus, stomach and duodenum was obtained with a good contrast passage, verifying the presence of a very large epinephrine diverticulum causing the symptoms. She was operated on using as approach route a previous middle incision and trans-hiatal route. A vagotomy, diverticulectomy, extended esophageal myotomy, anti-reflux procedure and temporary jejunostomy for the early feeding. Course was favorable and patient remains asymptomatic(AU)

Laparoscopic jejuno-jejunostomy for afferent loop stasis following truncal vagotomy with posterior gastro-jejunostomy for pyloric stenosis.

A 47-year-old man presented with epigastric pain relieved by bilious vomiting since one month. He had undergone truncal vagotomy with posterior gastrojejunostomy for benign gastric outlet obstruction 2 years ago. Endoscopy showed distension and stasis in the afferent loop, bile gastritis and esophagitis. Laparoscopic Braun jejunojejunostomy relieved his symptoms.

The effects of cholecystojejunostomy and biliary drainage on biliary motor / 华中科技大学学报（医学）（英德文版）

Simulating physiological neuronal and hormonal conditions during digestive and interdigestive periods, the study identified the changes of the motility of biliary system including bile duct and sphincter of Oddi (SO) before and after cholecystojejunostomy. Thirty-five rabbits were divided into five groups randomly. The experimental groups received the venous injection of CCK 10 ng/kg, erythromycin 10 mg/kg, atropine 3 micrograms/kg and L-NAME 10 mg/kg respectively. Each rabbit underwent manometry through introducing a three-lumen catheter via the papilla retrogradely, using the low-compliance papillary infusion system. Then the gallbladder and the upper segment of the jejunum was anastomosed and the manometric procedures repeated after one week. SO basal pressure was increased, contraction amplitude decreased, contraction time shortened after cholecystojejunostomy. L-NAME, CCK and erythromycin could all excite SO. L-NAME could increase basal pressure and contraction amplitude, CCK increase basal pressure contraction amplitude and frequency, and erythromycin increase contraction amplitude, respectively. But comparing with that before cholecystojejunostomy, the increasing extent was decreased. The tensional and spontaneous contractions of the SO were under the control of the neural and hormonal mechanism. The anastomosis of gallbladder and jejunum and the drainage of bile made the tensional contraction stronger, but the spontaneous contraction weakened after the operation due to the decreases of the sensitivity of SO to hormonal factors. The clinical symptoms may not be relieved when the patients with SO dysfunction accepted cholecystojejunostomy.

Alteraçöes da mucosa gástrica na gastrojejunostomia isoperistáltica e anisoperistáltica em rato / Alterations in the gastric mucosa after iso and anisoperistaltic gastrojejunostomy in rat

As gastrojejunostomias associam-se freqüentemente a manifestações pós-operatórias, em grande parte relacionadas ao refluxo de líquido biliopancreático para o estômago. Além dos sintomas, que podem ser intensos, encontram-se alterações degenerativas e reacionais do epitélio gástrico, displasias e formação de úlceras próximas à anastomose. Com o objetivo de se estudar as alterações da mucosa gástrica e a relação destas com o procedimento cirúrgico, procedeu-se à avaliação histológica da mucosa do estômago após a realização de anastomoses gastrojejunais isoperistálticas e anisoperistálticas. Foram confeccionadas gastrojejunostomias e fechamento duodenal não-associados à gastrectomia em dois grupos (n = 7) de ratos Holtzman. No trigésimo dia pós-operatório, retirou-se a peça cirúrgica composta pelo estômago e jejuno próximo à anastomose. No grupo com anastomose anisoperistáltica, houve maior área de alterações histológicas das glândulas gástricas da região da anastomose que no grupo isoperistáltico (P < 0,05). Foram encontradas três úlceras anastomáticas no grupo anisoperistáltico e somente uma no grupo isoperistáltico. Concluindo, a gastrojejunostomia anisoperistáltica não-associada à gastrectomia provoca mais alterações da mucosa gástrica e anastomáticas que a isoperistáltica, no modelo experimental utilizado.

Technical complications of feeding jejunostomy: a critical analysis.

INTRODUCTION: A retrospective review of patients undergoing feeding jejunostomy (FJ) was undertaken in order to evaluate procedure related complications and their impact on final outcome. PATIENTS AND METHODS: Ninety six patients had FJ at the department of Surgical Gastroenterology, SGPGIMS from January 1989 to December 1995. RESULTS: FJ as an adjunct was performed in 89 patients with predominantly oesophageal (n = 62) and pancreatic surgery (n = 17). Seven patients had FJ as the only procedure. Fifteen patients (15.2%) had complications related to FJ. Minor complications (7.2%) included dislodgement (n = 3), blockage of the tube (n = 2) and pericatheter leak (n = 2). Major complications (8.3%) which needed surgical intervention were, detachment of the jejunostomy from the abdominal wall (n = 3), leak into the peritoneal cavity (n = 3), jejunal perforation by the tip of the catheter (n = 1) and peritonitis after removal of the tube (n = 1). Procedure related mortality was 3.2%. CONCLUSIONS: FJ should not be treated as a minor procedure and due attention to the technical details is required in its performance, otherwise it may well become the cause of a poor result following a very successful major operation.

Indicaçöes e complicaçöes das derivaçöes biliodigestivas / Bilioenteric anastomosis: indications and complications

O objetivo do estudo é avaliar as indicaçöes mais frequentes das derivaçöes biliodigestivas e verificar quais säo os tipos mais realizados, seus resultados e complicaçöes. Revisou-se os registros dos pacientes submetidos a qualquer tipo de derivaçäo biliodigestiva realizado no serviço de cirurgia do aparelho digestivo do Hospital de Clíncias da Universidade Federal do Paraná, no período de 1 de janeiro de 1985 a 31 de dezembro de 1994. Vinte e cinco (31,6 por cento) homens e 54 (68,4 por cento) mulheres foram submetidos a derivaçäo biliodigestiva. A idade média dos pacientes foi de 54,8 anos. Dor abdominal mostrou ser o sintoma mais prevalente. O diagnóstico pré-operatório mais encontrado foi litíase da via biliar principal (49,4 por cento). A coledocoduodenostomia foi a cirurgia mais realizada. Vinte e cinco (69,6 por cento) pacientes tiveram um pós-operatório sem complicaçöes, e 24 (30,4 por cento) apresentaram algum tipo de complicaçäo. As derivaçöes biliodigestivas constituíram método eficaz de tratamento de diversas doenças e os resultados encontrados no serviço de cirurgia do aparelho digestivo do Hospital de Clínicas da Universidade Federal do Paraná, no que diz respeito às indicaçöes e complicaçöes, estäo em concordância com os da literatura
