Ansa pancreatica is a rare anatomic variation of pancreatic ducts. It’s a predisposing factor of recurrent pancreatitis. In this case report, we describe a case of a 24-year-old male suffering from an ansa pancreatica with a non-patent major papilla, diagnosed on magnetic resonance cholangiopancreatography (MRCP).The Ansa pancreatica was revealed by an episode ofacute pancreatitis attacks in chronic pancreatitis.Endoscopic retrograde cholangiopancreatography (ERCP) confirmed importantabrupt dilation in the main pancreatic duct with an ansa loop in the PD (pancreatic duct) in the head of the pancreas, and a sphincterotomy of the minor papilla was performed.The procedure was difficult and the placement of a long-term pancreatic stent during the ERCP was impossible, thus a surgical pancreatico-jejunostomy was proposed as a treatment of an ansa pancreatica with a non-patent major papilla.

Gastrointestinal stromal tumors (GISTs) arising from the rectum are rare. We report the case of an aggressive rectal gastrointestinal stromal tumor (GIST) in a 60-year-old female that presented for symptoms of constipation and lower gastrointestinal bleeding. Upon rectal examination, a hard mass was found at 6cm from the anal marge. An MRI was indicated that shows a well-demarcated lesion originates from the distal rectum with exophytic growth and central necrosis. The diagnosis of rectal gist was confirmed by colonoscopy with biopsy and immunohistochemical analyses of bioptic material. Liver metastases were seen on computerized tomography (CT). She was referred for palliative chemotherapy. The patient had suffered from intestinal obstruction three weeks after his initial presentation and passed away shortly thereafter. We aimed to report this case as an aggressive and rare GIST localization.

Le kyste hydatique est une zoonose qui touche fréquemment le foie, qui sévit à l´état endémique dans plusieurs pays comme le Maroc. L´hydatidose hépatique peut se compliquer d´une angiocholite dont le traitement de choix est actuellement la cholangio-pancréatographie rétrograde endoscopique avec sphinctérotomie. Nous rapportons deux cas cliniques d´angiocholite sur kyste hydatique hépatique fistulisé dans la voie biliaire principale qui ont été traités par voie endoscopique avec une évolution favorable. Le diagnostic précoce et la prise en charge adéquate permettent l´amélioration du pronostic de ces patients.
