An-unusual-complication-of-liver-abscess—hepatoduodenal-fistula

Liver abscess is an intra-abdominal infection characterized by localized pus collection with destruction of hepatic parenchyma. When a liver abscess ruptures and extends into adjacent structures, it leads to development of complications which further increases mortality rate. Involvement of peritoneal, pericardial and pleural cavity are often noted but, extension into gastro-intestinal tract is rare and unusual; with only a limited number of cases reported, we present a recently encountered case of liver abscess. The abscess was found to be complicated by formation of fistulous tract with duodenum.

Enterocutaneous fistulas due to stent migration. How reliable is its use on duodenal benign pathology? a case report

Duodenal stenting has been widely used on malignant pathology on selected patients with poor prognosis and advanced disease. In these last years, there has been a clear ampliation of the clinical applications of endoscopy procedures and stents. Its use on benign pathology is spreading but there is a lack of literature about the complications in this context. The incidence of stent migration is about 10-25% in self-expandable metal stent (SEMS), and 2-5% on covered self-expanding metal stents (CSEMS). We reported a clinical case of a 48 years old patient who developed a duodenal ulcer. The patient was submitted to exploratory laparotomy, with duodenal primary closure of the ulcer. Later, the patient developed a enterocutaneous fistula because of the duodenal leak. It was referred to our third level hospital to the hepatopancreatobiliary surgery service. A new exploratory laparotomy with duodenal exclusion was planned, but it was impossible to access due to frozen abdomen. CSEMS was placed in the duodenal bulb resulting in the resolution of leaking, but the stent could not be removed because of migration. The stent trajectory was followed by abdominal x ray and tomography. The patient developed multiple intestinal an fecal enterocutaneous fistulas. It was submitted to multiples endoscopies, colonoscopies and enteroscopy without any success to reaching it. It was decided to perform a right lumbotomy to extract the prothesis. The stent was surgically removed, a planned stoma was left on the right flank on the extraction site.

Fístula aorto-duodenal primaria: caso clínico / Primary aorto-duodenal fistula: clinical case

Resumen Introducción Las fístulas aorto-entéricas (FAE) son una causa infrecuente de hemorragia digestiva. El pronóstico, generalmente ominoso, depende de una alta sospecha clínica y diagnóstico oportuno. Caso clínico Reportamos el caso de una mujer de 66 años intervenida por un aneurisma sacular aórtico abdominal (AAA) yuxtarrenal, con rotura contenida, fistulizado al duodeno. Presentó una hemorragia digestiva en el preoperatorio; sin embargo, el diagnóstico de la fístula se hizo en el intraoperatorio. La paciente fue sometida a reparación quirúrgica urgente con instalación de una prótesis aórtica bifemoral y resección duodenal. En el postoperatorio inmediato presentó una trombosis parcial de las ramas de la prótesis aórtica e isquemia de extremidades, siendo reintervenida exitosamente. Discusión La FAE es una causa potencialmente fatal de hemorragia digestiva. El diagnóstico continúa siendo un desafío debido a su presentación inespecífica y siempre debiese ser considerado frente a una hemorragia digestiva sin causa aparente. Existen varias opciones para el enfrentamiento quirúrgico que deben ser analizadas caso a caso, sin retrasar la reparación de la fístula. Es preferible la resección duodenal ante la simple duodenorrafia.

Introduction Aorto-enteric fistulae (AEF) are a rare cause of gastrointestinal bleeding. The prognosis tends to be ominous, depending greatly in a high level of clinical suspicion and prompt diagnosis. Clinical case We report a case of a 66-year-old female with a saccular juxta-renal abdominal aortic aneurysm (AAA), with a contained rupture. The patient was urgently submitted to surgical repair using an bifemoral aortic prosthesis. A duodenal partial resection was performed. During the immediate postoperative time she presented partial thrombosis of prosthesis and ischemia of lower extremities so she was reoperated successfully. Discussion AEF is a potentially fatal cause of gastrointestinal bleeding. Diagnosis is still troublesome due to its vague presentation and it should always be considered when facing gastrointestinal haemorrhage with no apparent cause. There are several surgical approaches that should be pondered case to case without delaying the repair of the defect.

The 465th case: intestinal obstruction, gastrointestinal hemorrhage and duodenal fistula / 中华内科杂志

This is a complicated and difficult case. The onset symptom of a 62-year-old male was recurrent intestinal obstruction. Ileocecal and ileocolic operation was done twice. Massive gastrointestinal bleeding occurred due to giant fistula of descending duodenum, which connected to ileocolic anastomosis. After consultation by multidisciplinary team, jejunal-feeding tube was placed to provide enteral nutrition. With general condition improving, duodenal fistula repair and involved bowel resection were performed. Postoperative pathology confirmed Crohn's disease. The patient was treated with thalidomide and recovered well during follow-up.

Clinical value of multi-slice computed tomography in the diagnosis of biliary gallbladder-duodenal fistula / 中华消化外科杂志

Objective To summarize the characteristics and clinical value of multi-slice spiral computed tomography (MSCT) examination in the biliary gallbladder-duodenal fistula.Methods The imaging data of 28 patients with gallbladder-duodenal fistula who were admitted to the Wuxi No.2 Hospital of Nanjing Medical University between June 2012 and March 2015 were retrospectively analyzed.All the 28 patients received MSCT examinations,and the imaging changes were observed and analyzed,including the location of lesions,figures of fistulous tract,shrinking or enlarging gallbladder,pneumotosis and stones of gallbladder or bile duct.Results Of the 28 patients,fistula located at the duodenal bulb were detected in 14 patients,junction of the bulb and the descending part of the duodenum in 2 patients,ascending duodenum in 7 patients,horizontal part in 5 patients.Indirect signs of biliary gallbladder-duodenal fistula included that gallbladder volume in 28 patients was significantly reduced,cross sectional area of gallbladder was 2 cm × 1 cm-6 cm × 2 cm,and gallbladder wall was thickened with an average thickness of 5 mm (range,4-9 mm).Adhesion of gallbladder and duodenum,unclear boundary,structure disorder and visible effusion surrounding gallbladder were detected.Among 21 patients with biliary gas,19 patients had pneumotosis of gallbladder and 17 had biliary pneumatosis.Biliary stones were detected in 23 patients including cholecystolithiasis in 19 patients,gallbladder neck stones in 6 patients,common bile duct stones in 13 patients and intra-and extra-hepatic cholangiolithiasis in 1 patient.The diverticulum signs appeared in the duodenum of 11 patients.The direct signs of MSCT in the biliary gallbladder-duodenal fistula included that fistulous tract of 13 patients clearly showed and some were dumbbell-shaped.Two and 2 patients were complicated with gallstone ileus and multiple liver abscesses,respectively.The diagnostic results of MSCT in 28 patients were compared with the results of operative exploration,with an diagnostic concordance rate of 78.6％ (22/28),and the diagnostic concordance rate of gallbladder stones was 82.1％ (23/28).Conclusions The indirect signs of MSCT in patients with biliary gallbladder-duodenal fistula include pneumotosis of gallbladder or/ and biliary gas,gallbladder neck stones or common bile duct stones,gallbladder shrank,adhesion of gallbladder and duodenum,unclear boundary,diverticulum signs in the adhesions of duodenum and gallbladder,and clear orificium fistulae of gallbladder-duodenum is a direct sign of MSCT.

Surgical management of Crohn's disease complicated with duodenal fistula / 中华消化外科杂志

Objective To investigate the surgical management of Crohn's disease complicated with duodenal fistula.Methods The clinical data of 1 012 patients with Crohn's disease who were admitted to the Nanjing General Hospital of Nanjing Military Connnand from January 2002 to January 2014 were retrospectively analyzed.Of the 1 012 patients,22 were complicated with duodenal fistula,including 12 with ileocolonic anastomosis-duodenal fistula,7 with colo-duodenal fistula,2 with sigmoido-duodenal fistula and 1 with duodeno-enteric fistula.All patients received duodenal fistula repair + resection of diseased intestine.Patients were followed up via out-patient examination,phone call and email till May 2014.The condition of patients before and after enteral nutrition support was compared using the t test.Non-normal data were analyzed using the Mann-Whitney u test.Results Two patients with abdominal infection and 1 with gastrointestinal bleeding received emergent operation,and the other 19 patients received enteral nutrition support prior to operation.Three patients received emergent colostomy.Two patients had fistula at the duodenal anastomosis,and 1 patient was cured by enteral nutrition support + drainage for 12 days and the other 1 received reoperation.The energies provided by enteral nutrition and enteral + parenteral nutrition were (25.3 ± 2.1) cal/g and (28.5 ± 3.2) cal/g,respectively,and the time for nutrition support was (31 ± 5)days.The level of C-reaction protein and Crohn's disease activity index were decreased from 25 mg/L and 207 ± 111 before treatment to 2 mg/L and 117 ± 71 after treatment,with significant difference (u =53.000,t =0.942,P ＜ 0.05).The levels of body mass index,albumin and blood sedimentation rate were (17.0 ± 2.1) kg/m2,(35 ± 5) g/L and 26 mm/h before treatment,and (17.9 ± 2.8) kg/m2,(38 ± 5) g/L and 23 mm/h after treatment,with no significant differences (t =0.482,1.170,u =67.500,P ＞ 0.05).One patient was cured by enternal nutrition.Five patients received intestinal stoma and the other 13 patients received intestinal anastomosis.Twenty-two patients were followed up with the median time of 13.4 months (range,4.0-37.0 months).One patient had recurrence of ileocolonic anastomosis-duodenal fistula and received reoperation,and complications were not observed in the other 21 patients.Conclusions Selective operation is recommended for patients with Crohn's disease complicated with duodenal fistula.Enteral nutrition support is the first choice during the interoperative management.Resection of diseased intestine combined with repair of duodenal fistula after alleviation of Crohn's disease and malnutrition could achieve satisfactorv effect.

A Successfully Treated Surgical Case of Graft Duodenal and Colonic Fistula with Cardiopulmonary Arrest after Abdominal Aortic Graft Replacement / 日本心臓血管外科学会雑誌

A secondary aorto-enteric fistula can directly communicate with the gastroduodenal tract, colonic tract and the aorta in patients undergoing major surgery on the aorta, and this phenomenon is observed particularly often in patients who have undergone abdominal aortic graft replacement. We encountered a case of secondary aortoduodenal fistula and colonic fistula. The patient was a 60-year-old man who had previously undergone a graft replacement for an infra-renal abdominal aortic aneurysm. His present admission was due to episodes of gastro-intestinal hemorrhaging and he had also undergone an abdominal aortic graft replacement 2 months previously. The patient's bleeding was managed conservatively. A scar was observed in the duodenum based on the endoscopic findings. At 10 days after admission, abdominal computed tomography (CT) showed active bleeding from the graft in the third portion of the duodenum. We therefore diagnosed secondary aorto-duodenal fistula. Since this pathogenic state may lead to serious massive gastroduodenal hemorrhaging, both an accurate diagnosis and emergency operation are therefore essential to successful treatment. We immediately inserted an intra-aortic occlusion balloon catheter (IABO). Thereafter, another aorto colonic fistula was detected after laparotomy, for the first time. First, the old graft was removed and the direct closure of the duodenum was performed, followed by omentopexy, colostomy, colostoma and then the extra-anatomical revascularization between the left axillary and bilateral femoral arteries was carried out. Finally, an intestinal feeding tube was inserted. The patient fell into a state of cardiac arrest during the operation due to the uncontrolled active bleeding in spite of the presence of IABO. An emergency thoracotomy was thus performed in the left 4th intercostal region. The descending aorta was clamped, and then all of the planned procedures were performed in order. The postoperative course was eventful, however, the patient's lower thigh eventually had to be amputated due to ischemia of the clamped descending aorta. We encountered a case of graft duodenal and colonic fistula with cardio pulmonary arrest due to delayed diagnosis based on the endoscopic findings after abdominal aortic graft replacement. This case was successfully treated despite various difficulties in making a timely and accurate diagnosis.

Bouveret's syndrome: a case report and a review of the literature

Bouveret's syndrome is a gastric outlet obstruction caused by an impacted gallstone that passes through a cholecysto-gastric or cholecysto-duodenal fistula. An elderly woman visited a local clinic with nausea and abdominal pain. Abdominal computed tomography revealed a stone that was impacted in the duodenal lumen and a fistula between the gallbladder and duodenum. Malignancy could not be excluded due to the mass in the cystic duct showing enhancement and the presence of enlarged lymph nodes on computed tomography, and increased fludeoxyglucose uptake in the cystic duct on positron emission tomography. The patient underwent simultaneous cholecystectomy, segmental duodenectomy and gastro-jejunostomy. Pathological examination exhibited chronic inflammation and no primary cancer of the gallbladder and fistula.

Excepcional y compleja lesión duodenal por ingesta de objetos metálicos / Duodenal perforation caused by metallic objects: case report

We report a 20 years old schizophrenic male, with a history of ingestion of four metallic tubes through which mate tea is drunk, that was admitted to the hospital with abdominal pain. A plain abdominal film showed the metallic objects in the abdominal cavity. The patient was operated. Two of the tubes were perforating the second portion of duodenum and the other two were in the large bowel. The tubes were extracted and the bowel wall was repaired. Due to a bad postoperative evolution, on a second operation, an antrectomy and duodenal excision was carried out. A duodenal fistula appeared that closed after 30 days, when the patient was discharged.

Las lesiones duodenales graves por ingestión de cuerpos extraños son excepcionales y cursan con alta morbimortalidad a pesar de los avances en el diagnóstico, su manejo quirúrgico y endoscópico. Actualmente, para su resolución definitiva se requiere a veces de un tratamiento por etapas y mediante la combinación de diversos procedimientos. Se presenta un caso clínico de lesión multivisceral a partir de una perforación duodenal (tipo III) provocada por la ingesta de varios objetos metálicos (bombillas de mate), que asocia compromiso hepático y colónico y complicada con una fístula duodeno cutánea. Su manejo requirió de varios procedimientos de reparación duodenal, que se combinaron en etapas sucesivas. El excepcional tipo de agente lesional, la compleja situación que provocó y el análisis de la literatura, otorgan particular interés al tema.

Biliary-duodenal Fistula Following Radiofrequency Ablation Therapy for Hepatocellular Carcinoma / 대한소화기학회지

Hepatocellular carcinoma (HCC) is one of the most common malignant neoplasms occuring worldwide. Surgical resection currently provides the best chance of long-term tumor free survival, but the most HCCs are not candidates for surgical excision due to poor liver function or poor medical background. Numerous noninvasive alternatives to surgical resection have been introduced to treat liver cancers. Radiofrequency thermal ablation has begun to receive much attention as an effective and minimally invasive technique for the local control of HCC. The biliary system related complications after radiofrequency ablation has rarely been reported. We report a case of biliary-duodenal fistula with liver abscess after radiofrequency ablation for HCC. The case was treated by abscess drainage and antibiotics.

A Case of Tuberculosis of the Esophagus and Duodenum Associated with Pulmonary Tuberculosis / 대한소화기내시경학회지

Esophageal and duodenal tuberculosis are rare form of gastrointestinal tuberculosis. The common complications due to esophageal and duodenal tuberculosis are fistulous communications with the adjacent structures, perforation, obstruction, and upper gastrointestinal bleeding. Massive bleeding in esophageal and duodenal tuberculosis is quite rare. We encountered a case of a 55-year-old male who presented with hematemesis and melena. Esophageal and Duodenal tuberculosis with a duodenal fistula was diagnosed by an endoscopic and radiology examination. He improved after treatment with anti-tuberculosis medication over a 9 month period. We report this case of esophageal and duodenal tuberculosis associated with pulmonary tuberculosis with a review of the relevant literature.

Intestinal Tuberculosis with a Duodenal Fistula / 대한소화기내시경학회지

Intestinal tuberculosis is a common disease of extrapulmonary tuberculosis. A diagnosis of intestinal tuberculosis is difficult as the symptoms and laboratory findings are not specific for the disease. Intestinal tuberculosis may cause various complications, such as intestinal obstruction, intestinal perforation, intraabdominal abscess, intestinal hemorrhage and fistula formation. A duodenal fistula caused by tuberculosis is an especially rare condition. We experienced a case of intestinal tuberculosis with a duodenal fistula as a complication. The patient was a 25-year-old man that presented with weight loss and diarrhea. Esophagogastroduodenoscopy showed a deep ulcerative lesion on the third portion of the duodenum with a fistula opening. A histological finding revealed granulomatous inflammation with multinucleated giant cells. In addition, the result of a Tb PCR assay was positive. After two months of treatment with the appropriate medication, the symptoms improved and the fistula has closed completely. We report the case with a review of the literature.

A Case of Pancreatic Arteriovenous Malformation Presenting Upper Gastrointestinal Bleeding / 대한소화기내시경학회지

A pancreatic arteriovenous malformation (AVM) is a very rare disease entity that is usually asymptomatic; however, it may present with a massive gastrointestinal hemorrhage. Recent advances in cross-sectional imaging and the widespread availability of angiography have contributed to the diagnosis of this condition. A patient was transferred to our clinic due to unknown origin gastrointestinal bleeding and upper abdominal pain. Double balloon enteroscopy and duodenoscopy revealed a bleeding pancreatico-cholangio-duodenal fistula. We were able to diagnose an arteriovnous malformation with a pancreatico-cholangio-duodenal fistula by the use of angiography and from the post-operative pathological findings.

Choledocho-duodenal Fistula Caused by Tuberculosis / 대한소화기내시경학회지

Choledocho-duodenal fistula is a rare condition. It is usually developed as a complication of the gallstone disease, and rarely developed by penetrating peptic ulcer, trauma and neoplasm. Tuberculosis as a etiology of choledocho-duodenal fistula is very rare, and only a few cases were reported. We experienced a case of choledocho-duodenal fistula due to tuberculous lymphadenitis in a 26 year-old man presented with epigastric pain. After 6 months of anti-tuberculous medication, He was free of symptom and the fistula was closed spontaneously. We report the case with a review of literatures.

Diagnosis and treatment of cholecystoduodenal fistula / 中国普通外科杂志

Objective To explore the pathogenesis, pathomorphology, diagnosis and management of cholecystoduodenal fistula(CDF). Methods Clinical data of 11 cases of CDF admitted in our hospital in recent 17 years were analyzed retrospectively. Results All the patients were confirmed and treated by operation.Ten CDF were caused by cholecystitis and cholelithiasis,another one was caused by peptic ulcer.Only one case of CDF was diagnosed before operation. Nine patients were cured, and two patients died of severity infection of abdomen postoperatively. Conclusions Most CDF are caused by cholecystitis and cholelithiasis. X-ray film of abdomen,barium meal examination and endoscopic retrograde cholangiopancreatography(ERCP) are more useful for the diagnosis of CDF. The therapeutic principle of CDF is cholecystectomy,removing calculus, and repairing fistula with or without common bile duct exploration and/or bilioenterostomy.

Severe acute pancreatitis complicated with postoperative duodenal fistula / 中国普通外科杂志

Objective To study the causes and methods of prevention and treatment of severe acute pancreatitis (SAP) complicated with postoperative duodenal fistula. Methods Twenty-two cases with severe acute (pancreatitis) complicated with postoperative duodenal fistula were retrospectively analyzed . Results Among 184 patients with severe acute pancreatitis undergoing operative treatment,duodenal fistula developed in 22 (patients),and in 15 of the 22 (patients), it occurred 2 weeks after operation.In 18 patients the duodenal fistula healed spontaneously with conservative therapy and 4 patients were cured by re-operation. Conclusions (Duodenal) fistula is related to early operation for SAP,peripancreatic infection,and improper placement of (drainage) tube at time of operation or (prolonged) (placement) of (drainage) tube.Most duodenal fistulas can be (spontaneously) cured by maintaining patent drainage around the fistula, actively controlling peripancreatic (infection), suppression of gastrointestinal secretion, and augmention of nutritional support.
