A case of rectal Dieulafoy's ulcer and successful endoscopic sclerotherapy.

A 54-year-old woman presented a massive hematochezia 7 days after sigmoidectomy. Repeated colonoscopy and angiography failed to locate the site of bleeding and Hartman's operation was performed. Rebleeding from the rectum on the day of operation occurred and pulsate arterial bleeding with minimal surrounding ulcer 1 cm above the pectinate line was observed. Screlotherapy with ethanol and electro coagulation was successfully performed to achieve permanent hemostasis. The importance of detailed rectal examination and an awareness of this clinical entity in life-threatening lower intestinal bleeding is discussed.</p

Laparoscopic cholecystectomy in 3 cases of hemodialysis patients

Laparoscopic cholecystectomy has proven to be a safe and effective treatment for symptomatic gall stone disease. However, laparoscopic cholecystectomy in hemodialysis patients is considered to be relatively contraindicated because of anemia and bleeding tendency. We performed laparoscopic cholecystectomy in three patients being treated by hemodialysis for chronic renal failure. No significant complications were observed after surgery. Laparoscopic cholecystectomy should be considered for hemodialysis patients requiring cholecystectomy
