AI Article Synopsis
- Varices in the colon are an extremely rare cause of severe lower gastrointestinal bleeding, often linked to liver cirrhosis and related complications.
- A case study highlights a patient with significant colonic varices whose cause remained undetermined after three years of investigation.
- Understanding and recognizing colonic varices is crucial, as misdiagnosis during endoscopy could lead to unnecessary biopsies and severe bleeding.
Article Abstract
Varices of the entire colon are very rare. This rare cause of massive lower gastrointestinal hemorrhage is almost invariably associated with cirrhosis of the liver and consequent hypertension or portal venous obstruction. We report about a patient with massive lower gastrointestinal bleeding from extensive colonic varices. Despite extensive investigation and a follow-up of 3 years, the etiology of the colonic varices could not be determined. Only a few cases of apparent idiopathic (familial or non-familial) colonic varices have been described. Recognition of this abnormality is important, however, because colonic varices may be the cause of recurrent, frequently massive lower gastrointestinal hemorrhage. A misleading endoscopic diagnosis can lead to inappropriate biopsies, resulting in major bleeding.

Article Synopsis
- There is limited research on managing iron deficiency anemia following severe acute gastrointestinal bleeding, with existing studies mainly focusing on upper gastrointestinal cases and laboratory findings rather than clinical results.
- A retrospective analysis of 337 hospitalized adults showed that only 50% had iron studies ordered; among those tested, 75% had iron deficiency, but only a small percentage received appropriate iron treatments.
- By four months post-discharge, those treated with intravenous or oral iron showed significant improvements in hemoglobin levels, but patients with multiple health issues faced poorer clinical outcomes compared to those with fewer comorbidities.

Introduction: Ectopic gastrointestinal varicosities are defined as dilated portosystemic collateral veins that may localize anywhere in the gastrointestinal tract outside the gastroesophageal region. Ectopic colonic varices can be considered idiopathic when other etiology that related to portal hypertension or portal vein thrombosis have been excluded.
Case Presentation: A forty-five-year-old female patient has been under treatment for histopathologically confirmed ulcerative colitis since the age of 17.
Ileal pouch-anal anastomosis and end ileostomy result in equivalent graft survival following liver transplantation for inflammatory bowel disease-primary sclerosing cholangitis.

Introduction: Patients with inflammatory bowel disease and primary sclerosing cholangitis may require both liver transplantation and colectomy. There are concerns about increased rates of hepatic artery thrombosis, biliary strictures, and hepatic graft loss in patients with ileal pouch-anal anastomosis compared to those with end ileostomy. We hypothesized that graft survival was not negatively affected by ileal pouch-anal anastomosis compared to end ileostomy.

Colonic variceal bleeding is a rare cause of lower gastrointestinal (GI) bleeding, which carries a high mortality rate. Due to limited data, the optimal management of colonic variceal bleeding is not known. Coil-assisted retrograde transvenous obliteration (CARTO) has been shown to be very effective in managing non-esophageal variceal bleeding, but only a few cases demonstrate its effectiveness in treating colonic variceal bleeding.
