Clinical characteristics of double pylorus

Gastrocolic fistula as a complication of a gastric ulcer related to Helicobacter pylori in a child

Gastrocolic fistulas are very rare in children and their association with Helicobacter pylori is poorly described. We present the case of a 10-year-old boy with a history of chronic abdominal pain, diarrhea, halitosis, and growth delay diagnosed with H. pylori-associated gastritis and gastrocolic fistula. The boy recovered with resection surgery and antibiotic therapy for eradication of the pathogen. This is the first description of a gastrocolic fistula in pediatrics related to H. pylori.

Acquired double pylorus presenting as a gastrointestinal bleeding

We present the case of a 65‐year‐old man without a past medical history who was admitted for gastrointestinal bleeding. The case shows an acquired double pylorus due to probable pre pyloric ulcer.

Gastroduodenal fistula remains a rare inexplicable entity that can be congenital or acquired. If we consider our case as acquired DP, then the association with gastrointestinal bleeding appears to be an unusual complication of peptic disease. Congenital DP may account for our finding, also observed in the absence of peptic history.

Double Pylorus: Report of a Case With Endoscopic Follow-Up and Review of the Literature

Double pylorus is a rare endoscopic finding that has been reported in 0.001% to 0.4% of upper gastrointestinal endoscopies and can be either congenital or acquired. Acquired double pylorus is usually an uncommon complication of peptic ulcer that erodes and creates a fistula between the duodenal bulb and the prepyloric antrum. We describe a case of a 67-year-old man who experienced mild epigastric pain and dyspepsia over the last 6 months. The patient periodically took nonsteroidal anti-inflammatory drugs (NSAIDs) due to joint pain. Esophagogastroduodenoscopy revealed gastritis and a double pylorus. An accessory channel connected the lesser curvature of the prepyloric antrum to the duodenal bulb and the endoscope was able to be passed through both of the ducts. The Helicobacter pylori quick test proved positive. Two years later, a follow-up endoscopy showed that fistula fused with normal pylorus and there was a single large opening.

Acquired double pylorus: Clinical and endoscopic characteristics and four-year follow-up observations

Double pylorus (DP), or duplication of the pylorus, is an uncommon condition that can be either congenital or acquired. Acquired DP (ADP) occurs when a peptic ulcer erodes and creates a fistula between the duodenal bulb and the distal stomach. The clinical features and endoscopic characteristics of four patients with ADP were reviewed and compared with previously reported cases. An accessory channel connects the lesser curvature of the prepyloric antrum with the duodenal bulb, and in all cases, a peptic ulcer was located in or immediately adjacent to the accessory channel. In one of the patients, the bridge between the double-channel pylorus disappeared, resulting in a single large opening and duodenal kissing ulcer after two years and three months. Finally, nonsteroidal anti-inflammatory drugs, Helicobacter pylori and other risk factors associated with ADP are assessed.

Congenital double pylorus

The double pylorus is an uncommon finding and maybe congenital due to gastrointestinal duplication abnormality or more commonly secondary to peptic ulcer disease. The case we present is an elderly patient with mild dyspeptic symptoms who had an upper endoscopy as part of her investigative workup. The congenital double pylorus, being asymptomatic, may often go undetected. It is sometimes found incidentally on upper endoscopy, but needs no directed therapy. It is not associated with any specific complication.

Acquired double pylorus: a case report

Double pylorus is one of the rare anomalies of the gastrointestinal tract, it can be congenital or acquired. In this case we report a case of double pylorus because of chronic peptic ulcer. Upper GI endoscopy revealed gastroduodenal fistula located on the lesser curve of the antrum, the patient's symptoms were improved rapidly by intensive antiulcer treatment.

Acquired double pylorus, due to penetrating gastric ulcer, presenting with melena

Acquired double pylorus (DP) is an uncommon condition consisting of two communicating channels between the gastric antrum and the first part of duodedum. Little is known about the origin of DP. As there is no specific gastrointestinal symptom due to DP, most often it is diagnosed by gastroscopy while performing for other indicationsFew data are also known about the clinical course of DP. In the patients with peptic ulcer symptoms, the pyloroplasty-like drainage effect, improving gastric emptying after the estabilishment of the fistula, could relieve these symptoms. This represents an unresolved issues about the necessity of repeating endoscopy to document in the patients with DP its final outcome, as the risk of ulcer recurrence. We describe a case of a 76-years-old woman admitted to our department for hyposideremic anemia associated to a recent history of melena.

Double pylorus

Double pylorus is a rare abnormality and it occurs most commonly secondary to chronic peptic ulcer disease. It is usually treated conservatively with anti-ulcer therapy. However, refractory cases may require surgery.
