CT appearances of the Rapunzel syndrome: an unusual form of bezoar and gastrointestinal obstruction.

The CT appearances of an unusual type of trichobezoar which causes the Rapunzel syndrome are described. This syndrome is characterized by intestinal obstruction secondary to a bezoar possessing a tail which extends to or beyond the ileo-cecal valve. Most cases of bezoar are diagnosed with plain films or barium meal, but CT may be requested in patients who present with abdominal masses. The Rapunzel syndrome may be diagnosed with a combination of the CT findings and the history.

Small bowel Procardia XL tablet bezoar mimicking cystic pneumatosis intestinalis.

Procardia XL Extended Release Tablets are being used with increasing frequency in the treatment of angina and hypertension. Bezoar formation, secondary to retained insoluble medication shells, is an important but less well-known complication. We report the first case of a small bowel bezoar due to this unique medication system.

A bizarre bezoar: case report and review of the literature.

A bizarre case of a foreign-body bezoar is presented. A 16-year-old girl swallowed large amounts of toilet paper as a means of dieting. She presented with a palpable abdominal mass, multiple bezoars in the bowel, and paper excretion in the feces before admitting intentional ingestion of toilet-paper balls. Administration of Gastrografin via a nasogastric tube and enemas resulted in gradual excretion of the paper balls.

Small bowel obstruction caused by a congenital intestinal web with an enteric bezoar in an adult: report of a case.

An intestinal web is a rare congenital anomaly, typically reported in childhood, but often remaining asymptomatic throughout the entire life span of the individual. We report the case of a symptomatic intestinal web associated with an enteric bezoar in an adult, which to the best of our knowledge has never been documented before. A 25-year-old man presented with acute small bowel obstruction, and laparotomy revealed a stenotic area of the ileum as well as impaction of an enteric bezoar. We resected this segment of ileum and an intestinal web was subsequently found in the stenotic area. The patient recovered well and has remained asymptomatic for 3 years. Although rare, a congenital intestinal web may be a cause of adult small bowel obstruction requiring surgical resection.

Recurrent gastric bezoars. A new approach to treatment and prevention.

A recurrent gastric phytobezoar was successfully dispersed using an endoscopically directed intermittent jet of dilute papain. Dissolution analysis of a retrieved bezoar fragment showed pancrelipase and Adolph's Meat Tenderizer to be effective specific solvents. The patient remained free of symptoms while on a prophylactic regimen of pancrelipase taken daily. However, when the patient discontinued his medication, the bezoar recurred. The dissolution process was successfully repeated. Selecting a reagent on the basis of demonstrated effectiveness should enhance the chance of successful dissolution of a phytobezoar, whereas prophylactic doses of the reagent may prevent its recurrence.

Colonic intussusception secondary to a calcium phosphate bezoar in a child receiving calcium carbonate for hyperphosphatemia.

We report a case of a calcium phosphate bezoar resulting in colonic intussusception in a boy with chronic renal failure who received calcium carbonate to control hyperphosphatemia. Because of concerns about aluminum-related disease in patients receiving aluminum hydroxide phosphate binders, calcium carbonate is being used more frequently to manage phosphate retention in renal failure. The development of bezoars may complicate this new form of therapy.

Carpet bezoar obstruction of the small intestine.

Bezoars are food or fiber concretions of the alimentary tract, which infrequently cause intestinal obstruction. The authors describe a case of a 7-year-old child with pica in whom a synthetic fiber bezoar obstruction of the small intestine developed at the site of a previously stapled intestinal anastomosis.

Oesophagus bezoar diagnosed and removed endoscopically.

The authors describe the rare case of bezoar in the oesophagus. Their patient was sent to their Clinics with a diagnosed oesophageal tumor. The exact diagnosis was established by endoscopical examination. The bezoar was removed by endoscope, therefore, an operation was not necessary.

Small-bowel obstruction during enzymatic treatment of gastric bezoar.

A 66-year-old woman had a sudden onset of small-bowel obstruction during enzymatic treatment for gastric persimmon bezoar. Oral enzymatic therapy is the most effective method of treatment for large phytobezoars when endoscopic extraction is not possible. However, this report suggests that a further endoscopic intervention may be necessary in case the dissolved bezoars cause small-bowel obstruction during this form of therapy.

Antacid bezoar in a premature infant.

A premature infant with severe enteroviral infection was treated with Maalox for gastric bleeding. Bezoars formed, which were shown to contain high concentrations of magnesium. An association between antacid administration and bezoar formation in neonates has been previously suggested but has not until now been clearly documented.

[Bezoar with real and simulated complications].

A 64-year-old patient with lower abdominal complaints "come un sasso nel stòmaco" was admitted as an emergency with acute upper gastrointestinal haemorrhage. There was a discrepancy between the clinically unremarkable abdomen and the large amounts of free air subdiaphragmatically on the left side as seen in the radiograph. Endoscopy did not contribute greatly due to presence of a large "coagulum". Surprisingly, at operation a huge phyto-bezoar measuring 15 x 8 x 8 cm, and a benign pressure ulcer in the great curvature were found. The perforation had only been mimicked, the air sickle was within the stomach and was demarcated by the round upper pole of the bezoar.

Paper bezoar in the stomach.

A toilet paper bezoar caused acute abdominal distention and symptoms of an acute condition of the abdomen in a 5-year-old boy. Simple gastrotomy served to clear the paper bezoar and relieve the gastric obstruction after nonoperative methods failed.

Perdiem causes esophageal impaction and bezoars.

Perdiem is a bulk laxative (mostly psyllium) formulated as granules; these granules can adhere together and cause esophageal impaction and gastric bezoars. I have reported three cases of esophageal impaction caused by Perdiem. Although endoscopic manipulation is the currently favored treatment, bougienage relieved these impactions easily. One patient also had a gastric bezoar. Doctors and patients need to be aware of this potential complication from Perdiem.

Sunflower seed bezoar leading to fecal impaction.

We report the cases of two children, ages 8 and 10 years, with painful defecation and constipation due to impaction of sunflower seed shells that did not respond to laxative and enema therapy. Physical examination revealed a prickly mass in the rectal vault. Proctoscopy revealed bezoars of sunflower seed shells, which were removed by endoscopic biopsy forceps followed by a combination of rectal irrigation and manual disimpaction. The rectal pain resolved, and bowel habits returned to normal with laxatives. Patients with rectal bezoars who fail to respond to enemas or colonic lavage may require endoscopic management for resolution of their symptoms.

[Gastric food bezoar as a complication of bariatric surgery. Case report and review of the literature].

In the last few years bariatric surgery has become an excellent therapeutic alternative for the treatment of morbid obesity. Food bezoar as a cause for obstruction seems to be a very infrequent postoperative complication. It has only been published as anecdotal case reports. We describe a female patient with morbid obesity (weight, 131 kg; body mass index, 45) who underwent laparoscopic bariatric surgery (subtotal 95% gastrectomy with gastroyeyunoanastomosis in Roux-Y) obtaining a significant weight reduction (51 kg) in the next few months post surgery. She developed a food bezoar in the gastric remnant as a late complication of surgery (13 months after bariatric surgery) and presented as a gastric outlet acute obstruction with persistent vomiting and satiety. The diagnosis and treatment was performed through an upper GI endoscopy. It is important to consider this complication in patients with persisting vomiting after this kind of surgery. In the near future we will probably have a significant amount of patients operated due to morbid obesity and we may see this kind of complication more frequently.

Paraffin oil bezoar impacted in the small bowel: CT findings.

A case of a paraffin oil bezoar impacted in the small bowel, resulting from the prolonged use of paraffin oil as treatment for increasing constipation in a patient with metastatic ovarian carcinoma, is described. Although pharmacobezoars are reported in the literature, we could not find a description of the CT findings of a paraffin oil bezoar.

Gastric bezoar complicating laparoscopic adjustable gastric banding with band slippage.

Gastric bezoars may develop in the proximal pouch after gastric restriction, eg. by laparoscopic adjustable gastric banding (LAGB). To date, only two centers have reported this rare complication. We report an additional case with band slippage, to emphasize that bezoars should be considered in the differential diagnosis in patients presenting with new onset nausea and vomiting after LAGB.

Bezoar formation requiring endoscopic removal after intentional overdose of extended-release nifedipine.

A 61-year-old Caucasian woman was transported to the emergency department after intentionally ingesting several different prescription drugs. She had been found by her husband in an unconscious state with empty bottles of extended-release venlafaxine, extended-release nifedipine, sertraline, and atorvastatin. She was intubated in the emergency department and transferred to the intensive care unit. After 36 hours in the intensive care unit, she was stabilized and brought to a general medical ward. She later developed profound recurrent hypotension with systolic blood pressures ranging from 40-70 mm Hg and diastolic blood pressures of 0-40 mm Hg. She was readmitted to the intensive care unit, where a computed tomography scan revealed a mass in her stomach. A gastroenterology consultation was obtained, and an esophagogastroduodenoscopy (EGD) was performed, during which a large drug bezoar was discovered and removed. The drugs were identified as extended-release nifedipine with a few granules of extended-release venlafaxine. Unfortunately, the patient died 3 days after the EGD from multisystem organ failure related to the overdose. Clinicians who encounter drug overdoses should be aware of the possibility of drug bezoar formation and should consider endoscopic removal as a potential treatment option.
