Meckel's diverticulum (MD) is a true congenital diverticulum that is remnant by incomplete obliteration of the omphalomesenteric duct. It is the most common congenital anomaly of the gastrointestinal tract, with an estimated prevalence of 2% (0.3% to 3% in autopsy studies). About 90% of MD occurs within 100 cm of the ileocecal valve. A primary malignant tumor arising within an MD is extremely u...

Actinomycosis is a rare disorder caused by an anaerobic gram-positive bacillus (Actinomyces), predominantly by the Actinomyces israelii species. Only 20% of cases show an abdominal manifestation, the appendix and ileocecal valve being the most frequent locations. Definitive diagnosis is based on microbiological cultures, microscopy or macroscopy examination. Nevertheless, histological examinati...

Intussusception in adults lacks specific symptoms and is often diagnosed emergently when they present with obstruction. Though intussusception certainly varies in size and location, the increased likelihood of ischemia or obstruction make large intussusceptions very rare in the literature. A patient admitted to our facility for small bowel obstruction was found to have extensive intussusception...

Amebiasis is uncommon in developed countries. Several case reports in the literature emphasize that both the presenting symptoms and the radiological findings of colonic amebiasis closely resemble more common conditions, such as idiopathic inflammatory bowel disease and gastro-intestinal malignancy. We describe a unique case of colonic amebiasis (amebomas) coexisting with signet-ring cell carci...

A 56-years-old man with a small rectal carcinoid tumor without carcinoid syndrome was admitted at Chareongkrung Pracharak Hospital with rectal bleeding. Proctoscopy revealed a small 7-mm rectal polyp, at 6 cm above the dentate line. Histology was diagnostic of a carcinoid tumor without atypical histopathologic feature or invasion into the muscularis propria . Immunohistochemical study was posit...

A 67-year-old female patient with no medical history presents with pain and increased volume in her right lower limb for the last three weeks. She is admitted with a diagnosis of right-side iliac-femoral-popliteal deep venous thrombosis and bilateral pulmonary thromboembolism. She developed rectorrhagia following anticoagulation. Colonoscopy revealed an exophytic, mamillated, friable, anteriorl...

Gallstone ileus, a mechanical intestinal obstruction caused by the passage of a gallstone into the intestinal lumen through a fistula, although not common, deserves to more carefully studied due to its morbidity and mortality. Its incidence among older-age groups explains its association with chronic and degenerative diseases, which increase the complexity of the treatment choice. The need and ...

1 of 2 DESCRIPTION An elderly male who initially presented with a gangrenous left lower extremity and underwent bypass graft surgery was anticoagulated and presented with bloody bowel movements. A tagged 99mTc red blood cell scan was obtained using the Ultratag technique. This examination is recognised as the best screening method to detect active gastrointestinal bleeds. 1 – 3 The sensitivity ...

Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki). We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel ob...
