A Case of Double Pylorus Caused by Recurrent Gastric Ulcers: A Long-Term Endoscopic Observation

A rare endoscopic finding: acquired double pylorus

“…It is mostly found incidentally by endoscopic or X-ray examination [6]. In our case, the presenting symptom was gastrointestinal bleeding from the gastric ulcers, a condition rarely reported in the literature [7,8]. A long history of treatment with drugs including corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs) may also prohibit healing, contributing to fistula formation [2].…”

Double Pylorus: An Uncommon Endoscopic Finding

“…The reported prevalence of double pylorus is estimated between 0.02% and 0.4% and majority of the fistulas are located on the minor curvatura of the antrum [2,3]. In the clinical setting, double pylorus can present itself with epigastric pain, dyspeptic symptoms and upper gastrointestinal bleeding or can be found incidentally [4]. Treatment of this condition is mostly conservative, however patients who exhibit a more refractory progress may have underlying gastric carcinoma necessitating surgical therapy.…”

Acute upper bleeding due to an unusual complication of peptic ulcer disease: double pylorus

“…Since then, approximately 91 cases of double pylorus have been described in the literature. The prevalence in routine endoscopic and radiodiagnostic procedures is estimated at between 0.06 and 0.4% (3,5).…”
