Duodenal stenosis and duodenal atresia are well-known gastrointestinal anomalies in patients with Down syndrome. Although duodenal atresia presents early and classically with vomiting in the immediate neonatal period, the presentation of duodenal stenosis can be significantly more subtle and the diagnosis delayed. Here, we describe the case of a 5-month-old male infant with Down syndrome and de...

OBJECTIVE Metabolism of long-chain fatty acids within the duodenum leads to the activation of duodenal mucosal protein kinase C (PKC)-δ and the cholecystokinin (CCK)-A receptor to lower glucose production through a neuronal network. However, the interfunctional relationship between duodenal PKC-δ and CCK remains elusive. Although long-chain fatty acids activate PKC to stimulate the release of C...

A 67-year-old man with infected pancreatic necrosis underwent serial endoscopic necrosectomies through a spontaneously formed massive duodenal fistula (●" Fig.1). He also required percutaneous drainage of a communicating paracolic gutter collection. Despite resolution of necrosis, the fistula remained open with high-volume output through the percutaneous drain. The patient’s severe coronary dis...

Duodenal diverticular bleeding has traditionally required invasive surgical repair. With improvements in endoscopic devices, endoscopic treatment has become the main therapy for such bleeding [1,2]. However, the question of which endoscopic devices should be used is still controversial because of complications and recurrent bleeding after treatment [3]. A newly developed device, the overthe-sco...

Objective: The objective of this study was to assess the association between colorectal neoplasia and sporadic duodenal adenoma. Methods: A retrospective case control study was conducted using the databases of two major teaching hospitals in Western Australia. The frequency of colorectal neoplasia in patients with sporadic duodenal adenomas was compared with that in a control group of patients ...

BACKGROUND The pathogenic mechanisms involved in Helicobacter pylori-induced duodenal mucosal injury are incompletely understood. In the present study, we sought to investigate the effect of H. pylori vacuolating cytotoxin (VacA) on duodenal mucosal bicarbonate (HCO3-) secretion. METHODS Concentrated bacterial culture supernatants from an H. pylori wild-type strain producing VacA with s1/m1 g...

HYPOTHESIS Since the early 1990s, the laparoscopic technique has been increasingly used for the treatment of perforated peptic ulcer. It is important to validate a risk scoring system that can stratify patients into various risk groups before comparing the treatment outcome of laparoscopic repair against that of conventional open surgery. The scoring system should be able to predict the likelih...

OBJECTIVE Peptic ulcer disease in children is rare. Therefore, the diagnosis can be missed until complications such as perforation or hemorrhage occur. Few reports have investigated the procedures and outcomes of children who have undergone operations for perforated duodenal ulcers. We report our experience with the modified Graham technique for perforated duodenal ulcers in nine children and r...

INTRODUCTION Although the surgical treatment of patients with perforated duodenal ulcer is the method of choice, the introduction of effective pharmacotherapy has changed the surgical strategy. Nowadays less extensive procedures are chosen more frequently. The introduction of laparoscopic procedures had a significant impact on treatment results. AIM To present our experience in the treatment ...

Gastrointestinal stromal tumors (GISTs) originating in the duodenal wall constitute the most challenging localization for this gastrointestinal neoplasm. Duodenal GISTs are relatively uncommon. The prevalence of duodenal GIST is very low, accounting for 5% to 7% or less of all surgically resected GISTs. Most published reports on duodenal GIST are case reports or small case series. Consequently,...
