A Case of Successful Colonoscopic Treatment of Colonic Obstruction Caused by Phytobezoar

A phytobezoar is the most common type of bezoar, which is a gastrointestinal mass composed of vegetable. A persimmon is a common cause of a phytobezoar. The majority of bezoars are found in the stomach, with the small intestine being the next most commonly involved site. The colon is a rare site for a bezoar. Recently, we experienced a colonic bezoar that caused colonic obstruction in a 66-year-old female patient who took persimmons regularly. The patient came to the hospital because of abdominal pain and distension. To differentiate a tumor or other problems that can cause intestinal obstruction, we performed an abdominal computed tomography scan and found an ovoid intraluminal mass with a mottled gas pattern in the distal descending colon. A large impacted bezoar was seen in the sigmoid colon, which was completely obstructed, and it was successfully removed by using colonoscopy.

A Case of Buried Bumper Syndrome Complicated by Abdominal Wall Abscess in an Elderly Patient

The percutaneous endoscopic gastrostomy is used for nutritional support in patients requiring prolonged tubal feeding. Unfortunately, numerous complications, such as infection, stomal leak, fever, local pain, ileus and tube occlusion, have been reported since its introduction. The buried bumper syndrome is a rare but well-recognized long-term complication. The tight anchorage between the internal and external bumpers leads to gastric mucosal erosion and embedding of the internal bumper into the gastric wall, obstructing feeding. Our case involves an elderly patient with a buried bumper syndrome complicated by an abdominal wall abscess. A similar case has not been reported in Korea before. This article reports our findings and management with a review of the literature.
