Bezoars are concretions formed in the gastrointestinal tract. The trichobezoars are hairballs in the stomach or intestines composed of hair. They are usually found in young girls as in our case which we operated in April 1989 on Surgical Ward in Kartal State Hospital in Istanbul. The postgastrectomy state predisposes to bezoar formation. Persimmon peels or pits, orange or grapefruit pulp are the usual offenders. Bezoars are associated with vague upper gastrointestinal discomfort, nausea, and vomiting. The patients may complain of abdominal pain. Ulceration, bleeding, obstruction, and perforation are the most common complications. Treatment consist of mechanical fragmentation via the endoscope or operative extraction. Dissolution of the undigested bolus by ingestion of proteolytic enzymes such as papain may be tried. As prophylaxis the postgastrectomy patient must be warned of ingesting citrus fruits.

Gastroparesis is delayed gastric emptying of either solids or liquids, which occurs in the absence of mechanical obstruction. Although associated with many diseases, the most frequent cause of gastroparesis is diabetes mellitus. It is estimated that up to 50% of diabetic patients may have this problem. Symptoms of gastroparesis include postprandial nausea, epigastric pain/burning, bloating, early satiety, excessive eructation, anorexia and vomiting. The vomiting associated with gastroparesis often has the following two features: (1) emesis of undigested foods ingested more than four hours previous; and (2) emesis of undigested foods in the middle of the night or in the morning prior to eating breakfast. It is important to recognize and treat gastroparesis not only to decrease symptoms but also to prevent bezoar formation and nutritional deficiencies as well as to improve glycemic control in brittle diabetics. The purpose of this article is to review the physiology of gastric emptying and to use this information to understand the pharmacological therapies for this debilitating problem.

Gastric bezoar is an uncommon complication following Roux-en-Y gastric bypass (RYGBP). We report two cases of bezoar formation that occurred following laparoscopic RYGBPs. In both cases, the patients presented with abdominal pain, nausea, and "frothy" vomiting. The patients were successfully treated by endoscopic fragmentation and removal of the bezoar.

Rapunzel syndrome is a rare presentation of a trichobezoar, with 24 cases having been reported in literature so far. This syndrome has been reported in 23 female and 1 male patient with a mean age of 10.8 years. The patients commonly present with abdominal pain, nausea, vomiting and signs of obstruction. The distal end of the bezoar may be in the jejunum, ileum or the colon. We evaluate the various cases reported and discuss the various modes of presentation of this uncommon syndrome, and also present a series of 3 cases, all females, aged 16, 18 and 21 years, and had a trichobezoar in the stomach with a tail extending into the ileum.

We report a case of gastric bezoar-induced gastric outlet obstruction that was successfully treated with a combination of endoscopic injection and irrigation with Coca Cola. A 73-year-old diabetic woman had a history of perforated peptic ulcer and had received pyloroplasty more than 20 years previously. She had been ingesting Pho Pu Zi (Cordia dichotoma Forst. f.) as an appetizer for 1 month. She presented with epigastric pain, nausea, and vomiting. Upper gastrointestinal endoscopy, performed at a local hospital, showed 2 gastric bezoars in the stomach, and 1 of them impacted at the pylorus. She was referred to our emergency department for removal of the gastric bezoars that were suspected to be causing gastric outlet obstruction. All attempts at endoscopic removal using a polypectomy snare, biopsy forceps and Dormia basket failed. We then injected Coca Cola directly into the bezoar mass, followed by irrigation with Coca Cola. Follow-up endoscopy was performed the next day, which revealed that the gastric bezoars had dissolved spontaneously.

Bezoars are the most common foreign bodies of the gastrointestinal tract. Clinical manifestations vary depending on the location of the bezoar, from no symptoms to acute abdominal syndrome. The ingestion of cling film, which is used for preserving food, may lead to a mechanical obstruction of the gut, especially at the second portion of the duodenal segment, and could manifest with abdominal pain, epigastric distress, nausea, vomiting, and fullness. We report the case of a 72-year-old man who presented with gastric outlet obstruction after accidentally ingesting cling film. He completely recovered after it was endoscopically removed. Cling film is not toxic but has erosive effects. Endoscopic removal of such material is recommended. Moreover, psychiatric intervention and management is imperative to prevent recurrence in such cases.

An unusual form of bezoar extending from the stomach to the small intestine or beyond has been described as Rapunzel syndrome. Bezoars are concretions in the gastrointestinal tract that increase in size by continuous accumulation of non-absorbable food or fibers. Most bezoars in children are trichobezoars from swallowed hair from the head, dolls, or brushes. Trichobezoars typically cause abdominal pain and nausea, but can also present as an asymptomatic abdominal mass, progressing to abdominal obstruction and perforation. Trichobezoar with Rapunzel syndrome is an uncommon diagnosis in children with less than 40 cases reported. It is predominantly found in emotionally disturbed or mentally retarded youngsters. We present the youngest case of Rapunzel syndrome in the United States, a 5-year-old girl with mental retardation who presented with abdominal pain, vomiting and a non-tender abdominal mass.

This report presents the rare case of a 75-year-old woman who developed a rectal obstruction caused by a pharmacobezoar, following the long-term ingestion of magnesium oxide cathartics for constipation. She was admitted to the hospital with lower abdominal pain and nausea. Abdominal computed tomography and magnetic resonance imaging showed that a huge calcified mass caused the rectal obstruction. A divided sigmoid colostomy was performed to relieve her symptoms, a colonoscopy from the distal stoma delineated a huge bezoar in the rectum, and thereafter she underwent an enterotomy. Magnesium oxide was detected in an analysis of a sample from this bezoar. Phamacobezoars resulting from laxatives or cathartics have rarely been reported. The current report showed a rectal obstruction caused by a pharmacobezoar composed primarily of magnesium oxide.

A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. A trichobezoar is a bezoar made up of hair and is a rare cause of bowel obstruction of the proximal gastrointestinal tract. They are seen mostly in young women with trichotillomania and trichotillophagia and symptoms include epigastric pain, nausea, loss of appetite and bowel or gastric outlet obstruction. We herein describe a case of a trichobezoar that presented as a gastric outlet obstruction and was subsequently successfully removed via a laparotomy.

The case report describes a 13 years old girl, who presented with 3 days history of nausea. She had a hard palpable mass in abdomen and anaemia. There was a history of hair ingestion for the past 3 years, which gave the first clue to the diagnosis of trichobezoar. Radiology helped diagnose the condition with basic modalities including ultrasound, plain X-ray abdomen and upper gastrointestinal contrast study. The diagnosis was confirmed by endoscopy and the bezoar was successfully removed by gastrotomy.
