Thirty-four consecutive patients presenting to the Endoscopy clinic of the Ahmadu Bello University Teaching Hospital, Zaria with symptoms of upper abdominal pain were investigated for chronic duodenitis by endoscopy and histology and for associated diseases. Twenty-two patients had histological evidence of chronic duodenitis. No clinical features separated these from those who had no duodenitis. Endoscopy was a good enough tool for diagnosis. Stool parasites were significantly commoner in those with histological duodenitis. Gastritis was also commoner in those with duodenitis. Ranitidine appeared superior to polycrol in relieving symptoms. Endoscopy is useful in the diagnosis of severe duodenitis. Specific ulcer healing drugs may be tried in treating symptoms associated with duodenitis, though their effectiveness is still open to further research.

Cholecystoenteric fistulas are a rare complication of chronic gallstone disease. If not diagnosed on time, they can cause several complications such as gallstone ileus, gastric outlet obstruction (Bouveret syndrome), cholangitis, or liver abscess. We present a case of a patient with chronic calculous cholecystitis, who was admitted due to unspecific abdominal discomfort and impaired liver function with increased cholestatic liver enzymes.

Celiac disease (CeD) is a chronic, lifelong, multifactorial, polygenic, and autoimmune disorder, characteristically triggered by exposure to the exogenous factor "gluten" in genetically predisposed individuals, with resulting duodenal inflammation and enteropathy, as well as heterogeneous multisystemic and extraintestinal manifestations. The immunopathogenesis of CeD is complex, favored by a peculiar human leukocyte antigen (HLA) genetic predisposition, leading to gluten presentation by antigen-presenting cells to CD4+ T helper (Th) cells, T cell-B cell interactions, and production of specific antibodies, resulting in the immune-mediated killing of enterocytes and, macroscopically, in duodenal inflammation. Here, the most relevant correlations between cellular and molecular aspects and clinical manifestations of this complex disease are reviewed, with final considerations on nutritional aspects for disease management.

: Bouveret syndrome, a rare and often underdiagnosed variant of gallstone ileus, is characterized by the presence of a large gallstone impacted in the proximal duodenum, resulting in significant gastric outlet obstruction and aerobilia. Early identification of Bouveret syndrome is crucial for developing an appropriate surgical strategy. : A 76-year-old female underwent a contrast-enhanced abdominal CT scan, which revealed a cholecysto-duodenal fistula with a 3.

Background: Prepancreatic postduodenal portal vein (PPPV) is a rare anatomic variant where the portal vein (PV) runs anterior to the pancreas and posterior to the duodenum. Only 20 cases of PPPV, all in adults, have been reported in literature. We report the first case of PPPV in a pediatric patient discovered intraoperatively during total pancreatectomy with islet autotransplantation (TPIAT) and the third known case in which the PPPV could be isolated intraoperatively.
