Ileal Pouchitis With Endoscopic Pictures.

Ulcerative colitis (UC) is an inflammatory disorder, and almost one-third of UC patients ultimately undergo surgical interventions because of complications or refractory disease. Current restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard intervention for severe chronic UC with refractory disease. Several complications associated with this procedure can occur, including anastomotic leak, sepsis, and pouch ischemia. The most frequent long-term complication is pouchitis, an idiopathic inflammatory condition involving the ileal pouch. Presentations may vary but include stool frequency, urgency, incontinence, fatigue, malaise, and fever, less commonly bloody stools. We report a case of ileal pouchitis in a young patient, two years after proctocolectomy with IPAA responsive to antibiotic treatment. Our case supports that imaging studies like flexible sigmoidoscopy are necessary to rule out other disorders in patients with pouchitis.

Recurrent Hematemesis From Downhill Esophageal Varices: A Therapeutic Challenge for Gastroenterologists.

Downhill or upper esophageal varices have an etiology that differs from that of the "uphill" varices secondary to portal hypertension. Approximately 0.1% of all cases of variceal hemorrhage are due to downhill varices. The underlying etiology is obstruction of the superior vena cava (SVC) which results in the shunting of blood from the systemic circulation into the esophageal plexus, predominantly the upper two-thirds. The management should be directed to relieve the vascular obstruction. One of the causes of SVC obstruction leading to downhill variceal bleeding is dialysis catheter-associated SVC stenosis. We report the case of a 34-year-old male with hematemesis associated with downhill varices due to chronic SVC obstruction because of a central venous catheter.
