IgG4-related disease of the hepatobiliary tract : 2 case reports and review of the literature
IgG4-related disease is a rare inflammatory disorder that may mimic many infectious, malignant, and autoimmune conditions. The biliary tract is frequently involved, but hepatic lesions are rarely seen. Diagnosis is often delayed due to the absence of specific clinical and radiological signs, and the lack of an accurate diagnostic marker. Differential diagnosis includes cholangiocarcinoma, primary sclerosing cholangitis and intrinsic or metastatic liver disease. Corticosteroids are the cornerstone of therapy but treatment has not been standardized and relapse is common. Based on two cases of IgG4-related hepatobiliary disease, we review the current literature on this pathological entity. (Acta gastroenterol. belg., 2018, 81, 83-87).
When perforation is not the culprit : case report and systematic review of mechanical small-bowel obstruction complicating colonoscopy
Colonoscopy is generally safe, although expansion of colorectal cancer prevention programs is likely to increase the number of post-colonoscopy complications. We report the case of a 42-year- old woman with a prior history of 2 cesarean section deliveries who developed abdominal pain after an otherwise uneventful screening colonoscopy. Urgent exploration revealed closed-loop obstruction involving the terminal ileum, caused by an adhesive band close to the site of her previous Pfannenstiel incision. A systematic review of the literature revealed 11 reports (1985-2008) describing a total of 13 cases of mechanical small bowel obstruction (MSBO) after colonoscopy, 9 of which were confirmed by laparo- tomy. Colonoscopy-induced MSBO is practically impossible to anticipate, and only a prior history of abdominal/pelvic surgery may be deemed as a predisposing factor. However, it is related to significant morbidity, as it often leads to an ischemic bowel with need for surgical resection. Thus, endoscopists should be aware and maintain a low operative threshold to this rare, but hazardous, complication of colonoscopy. (Acta gastroenterol. belg., 2018, 81, 89-92).
Hepatic schistosomiasis with massive splenomegaly: a case report and literature review
Schistosomiasis is a parasitic disease caused by Schistosoma species. Intestinal and hepatic schistosomiases are the most common forms of chronic disease. We describe a case of a 26-year old patient from Eritrea who was referred to our hospital with abdominal pain and diarrhea. The diagnosis of hepatosplenic schistosomiasis was made by liver biopsy and the patient was treated with praziquantel. Hepatic schistosomiasis is characterised by deposition of schistosomal eggs in the liver which results in a host cell immune response and leads to granuloma formation and neo- angiogenesis. This is hallmarked by different grades of periportal fibrosis with portal hypertension leading to splenomegaly. Normal liver architecture is preserved and periportal fibrosis can be reversible if treated adequately and timely.
With a recent native schistosomiasis cluster report from France and the expected influx to Europe of persons from regions endemic for schistosomiasis, increased awareness of this disease in healthcare practitioners is needed. We review the epidemiology, pathogenesis, clinical presentation and treatment of schistosomiasis. (Acta gastroenterol. belg., 2018, 81, 93-96

Intraductal papillary neoplasm of the bile duct : case report and review of the literature
A variant of bile duct carcinoma, intraductal papillary neoplasm of the bile duct (IPNB) is a rare disease mainly found in Eastern Asia which encompasses a spectrum of intraductal papillary growth occurring anywhere along the intrahepatic and/or extrahepatic biliary tree that carries a high potential for malignancy. We report the case of a patient with episodes of recurrent cholangitis that was diagnosed with IPNB, our clinical and diagnostic approach, the radiographic and endoscopic findings, the interventions used, while discussing the therapeutic options. (Acta gastroenterol. belg., 2018, 81, 97-99).
