Most cholecystocolic fistulae are late complications of gallstone disease, but can also develop following carcinoma of the gallbladder when the necrotic tumor penetrates into the adjacent colon. Although no currently available imaging technique has shown great accuracy in recognizing cholecystocolic fistula, abdominopelvic computed tomography may show fistulous communication and anatomical details.Herein we report an unusual case of cholecystocolic fistula caused by gallbladder carcinoma, which was preoperatively misdiagnosed as hepatic flexure colon carcinoma.展开更多

Currently, radiological embolisation is considered the first-line therapy for simple IAPF; however, it might be not resolutive for complex hepatic vascular lesions. When endovascular embolization is not sufficient to completely obliterate the IAPF, surgical intervention is needed, but it has been associated with severe morbidity and mortality in small children.Furthermore, indications are not defined.CASE SUMMARY We present the first case of a 6-month-old girl with trisomy 21 affected by a complex congenital IAFP, which caused severe PH, successfully treated with an endovascular-surgical hybrid procedure. The novel technique comprised a multistep endovascular embolisation, including a superselective transarterial embolisation of the afferent vessels and a direct transhepatic embolisation of the dilated portal vein segment, combined with selective surgical ligation of the arterial branches that supply the fistula, which were too small to be embolised.The complex IAPF was also associated with severe cholestasis and intra/extrahepatic biliary tree dilatation, which was successfully treated by a temporary biliary drainage. At 24-mo follow-up, the hybrid endovascularsurgical procedure achieved complete occlusion of the complex IAPF and resolution of the PH. A comprehensive review of the literature on congenital IAPF management, focussed on alternative treatment strategies, is also reported.CONCLUSION The combined radiological-surgical approach is a safe and effective treatment option for complex IAPF and avoids major invasive surgery.展开更多

Intrahepatic APFs are extremely rare and are a cause of presinusoidal portal hypertension. Etiologies for APFs are comprised of precipitating trauma, malignancy, and hereditary hemorrhagic telangiectasia, but these were not the case in our patient. Idiopathic APFs are usually due to congenital vascular abnormalities and thus usually present in the pediatric setting. This is one of the first cases of adult-onset isolated APF who presented with portal hypertension and was successfully managed through endoscopic hemostasis and subsequent interventional radiological embolization.展开更多

Although ERCP represents an excellent technology, it is not without attendant risk including sepsis, bleeding and perforation. In this case report, the first of its kind, is described the occurrence of a migrated biliary stent induced duodenal-colic fistula formation in a liver transplantation patient who had required dual biliary stenting given post-operative biliary structuring. The placement of dual stents and their size are likely implicated in the cause of perforation. The enteric anatomy and the medical immunosuppression likely contributed to a delay in diagnosis and worse outcome.展开更多
