A Ruptured Cystic Artery Pseudoaneurysm with Concurrent Cholecystoduodenal Fistula: A Case Report and Literature Review

Pseudoaneurysms of the cystic artery and cholecystoduodenal fistula formation are rare complications of cholecystitis and either may result from an inflammatory process in the abdomen. A 68-year-old man admitted with acute cholecystitis subsequently developed massive upper gastrointestinal (GI) bleeding. Abdominal computed tomography showed acute calculous cholecystitis and hemobilia secondary to bleeding from the cystic artery. Angiography suggested a ruptured pseudoaneurysm of the cystic artery. Upper GI endoscopy showed a deep active ulcer with an opening that was suspected to be that of a fistula at the duodenal bulb. The patient was managed successfully with multimodality treatment that included embolization followed by elective laparoscopic cholecystectomy. Presently, there is no clear consensus regarding the clinical management of this disease. We have been able to confirm various clinical features, diagnoses, and treatments of this disease through a literature review. A multidisciplinary approach through interagency/interdepartmental collaboration is necessary for better management of this disease.

Íleo biliar: reporte de un caso de fístula colecistoduodenal asociada a hernia inguinal izquierda / Gallstone ileus: a case report of cholecystoduodenal fistula associated with leftinguinal hernia

Biliary ileus, first described byThomas Bartholin in the year1654, is a rare cause of mechanical ileus (small bowel obstruction) (1-3% in patients younger than 65 years), increasing significantly from that age (25%). The necessarycondition forthis pathologyis the presence ofa fistula between the gallbladderandthe gastrointestinaltract. Simple abdominal X-ray and ultrasonography are widely available and of relatively low cost, together presenting a sensitivity of 74% when they show the classic signs of Rigler’s triad (pneumobilia, ectopic gallstone and dilated loops of small intestine), but computed tomography of the abdomen is considered the gold standard, with a sensitivity and specificity higher than 90%. The aim of this article is to present a case of radiological diagnosis of biliary ileus in a patient with vesicular lithiasis + cholecystoduodenal fistula, associated with inguinal hernia on the left.

El íleo biliar, descrito por primera vez por Thomas Bartholin en el año 1654, constituye una causa poco frecuente de íleo mecánico (1-3% en menores de 65 años) aumentando significativamente a partir de esa edad (25%). La condición necesaria para esta patología es la presencia de una fístula entre la vesícula biliar y el tracto gastrointestinal. La radiografía simple de abdomen y la ecografía son de amplia disponibilidad y coste relativamente bajo, presentando en conjunto una sensibilidad del 74% cuando manifiestan los signos clásicos de la tríada de Rigler (neumobilia, lito biliar ectópico y dilatación de asas de intestino delgado), pero se considera que la tomografía computada de abdomen es el gold standard, con una sensibilidad y especificidad superiores al 90%. El objetivo de este artículo es presentar un caso de diagnóstico radiológico de íleo biliar en un paciente con litiasis vesicular + fístula colecistoduodenal asociadas a hernia inguinal izquierda.

Squamous Cell Carcinoma of the Gallbladder Presenting with a Cholecystoduodenal Fistula / 계명의대학술지

Gallbladder cancer (GBC) is the most common primary hepatobiliary carcinoma and the sixth most common gastrointestinal malignancy. Adenocarcinoma accounts for the vast majority of GBCs (80–95%), whereas squamous cell carcinoma constitutes only 0–3.3% of GBCs. A 69-year-old man was suspected to have GBC with a cholecystoduodenal fistula on an abdominal computed tomography scan. He underwent esophagogastroduodenoscopy, which revealed that the duodenum was obstructed by the mass. Duodenal and biliary stents were successfully placed using endoscopic retrograde cholangiopancreatography. Pathology obtained from the duodenum revealed the mass to be a squamous cell carcinoma.

Gastric Outlet Obstruction arising from Xanthogranulomatous Cholecystitis accompanied by both Cholecystoduodenal and Cholecystocolonic Fistulas / 대한췌담도학회지

Xanthogranulomatous cholecystitis (XGC) is a rare type of chronic inflammation of the gallbladder characterized by focal or diffuse destructive inflammatory responses. Although it is a benign condition, its destructive course may lead to more aggressive outcomes of the gallbladder, such as local infiltration, fistula, stricture, and perforation as compared with other gallbladder inflammations. There are reports about XGC accompanied by cholecystoenteric fistula. However, XGC accompanied by more than one cholecystoenteric fistula is rare. We report a case of a 54-year-old man with gastric outlet obstruction arising from XGC, accompanied by cholecystoduodenal fisula and cholecystocolonic fistula, but without impacted gallstones.

Mirizzi Syndrome Type II with Cholecystoduodenal Fistula: An Infrequent Combination

We report a case of Mirizzi syndrome type II associated with biliary enteric fistula. It is important to identify this combination early, as it is associated with high morbidity. In our case, intraoperative findings were cholecystoduodenal fistula and communication of Hartmann’s pouch with common bile duct (CBD). A subtotal cholecystectomy with excision of cholecystoduodenal fistula was performed. A minimal surgical maneuver of Calot’s Triangle with repair of cholecystoduodenal fistula is required during the intraoperative period.

Cholecystoduodenal Fistula: An Intraoperative Diagnosis.

We report a case of chronic cholecystitis that had no preoperative diagnosis of cholecystoduodenal fistula but was found during laparoscopic cholecystectomy and was managed successfully. I

Acute Acalculous Cholecystitis Associated with Cholecystoduodenal Fistula and Duodenal Bleeding: A Case Report

Although acute acalculous cholecystitis (AAC) accounts for less than 10% of acute cholecystitis in the adult population, gangrene and perforation are much more frequent compared to the usual cases of acute cholecystitis (calculus cholecystitis). However, spontaneous biliary-enteric fistula is well recognized in AAC, 90% of which are cholecystoduodenal fistula (CDF) though it is an uncommon disorder. The majority of the CDF are caused by cholelithiasis. As patients are usually associated with complicated clinical illness, the diagnosis is often difficult to make and required surgery is often delayed. We have studied a rare complication of acute acalculous cholecystitis which was presented as intermittent upper gastrointestinal bleeding. Ulceration of the superficial branch of the cystic artery has been observed due to acalculous cholecystitis associated with a cholecystoduodenal fistula. We have performed a transfixing ligation of the bleeding vessel, cholecystectomy and simple closure of the CDF. We have finally made a diagnosis of early gallbladder cancer through a frozen section. There was no serious complication after the operation and the patient has achieved an uneventful recovery.

Two Cases of Ectopic Gallstones Treated by Endoscopic Therapy / 대한소화기내시경학회지

Two cases are herein reported involving patients with ectopic gallstones which were discharged into the stomach and duodenum through a cholecystoduodenal fistula and successfully removed by endoscopic therapy. In the first case, a 75-year-old man was admitted with epigastric pain. Simple abdomen film demonstrated a round laminated calcification and air biliarygram in the RUQ. Endoscopic examination revealed a fistula on the posterior wall of the duodenal bulb and a brown stone (about 5 cm in diameter) was found in the second portion of the duodenum, It was demolished through endoscopic electrohydraulic lithotripsy (EEH1) and discharged with the stool. In the second case, a 55-year-old man was admitted with epigastric pain. A CT scan revealed an ovoid laminated calcification in the dependent portion of the stomach. Endoscopic examination revealed a fistula on the anterior wa11 of' the duodenal bulb and a black pigmented stone (about 2.5 cm in diameter) was found in the stomach. This stone was removed orally by an endoscopic snare. These patients were discharged and remained asymptomatic.
