Gastric bezoar caused by lecithin: an unusual complication of health faddism.

We discovered an unusual bezoar in a previously healthy man who had been ingesting large amounts of a vegetable-derived oil touted to contain lecithin, which he purchased from health food stores in the belief that it had beneficial effects in lowering cholesterol levels and improving memory. The large intragastric mass, composed of fatty acids and lecithin, led to considerable morbidity, including abdominal pain, early satiety, and significant weight loss, and required surgical removal.

Intestinal obstruction from cecal bezoar; a complication of fiber-containing tube feedings.

Dietary fiber increases stool bulk, regulates bowel transit time, and decreases intraluminal pressure. Because these actions constitute a natural way to stop diarrhea, a frequent problem with tube feedings, enteral tube feeding manufacturers have marketed several fiber-containing formulae. While bulk-forming agents such as fiber may not be appropriate for every tube-fed patient, we were unable to find any published contraindications to the use of fiber-containing enteral products. We present the case of a seriously ill man who received a fiber-containing tube feeding while also getting intestinal motility-suppressing medications. A large fiber bezoar developed, with resultant mesenteric hemorrhage. We conclude that fiber-containing tube feedings are contraindicated in certain types of patients.

Small-bowel obstruction after conservative treatment of gastric bezoar.

Gastric bezoar is an uncommon complication of gastric procedures. Increasingly it is managed by pharmacologic or endoscopic manipulations. The risk of intestinal obstruction after nonsurgical therapy is illustrated by two cases that were successfully managed without resorting to enterotomy.

[Mixed bezoar].

The case of an adolescent psychopath who, following traumatic psychological experiences, ingested her own hair and cotton string over a 6 to 8 month period, is presented. This resulted in the formation of a mixed bezoar (hair and cotton string) with subsequent deterioration of her general condition. The diagnosis was made roetgenographically. Curative surgery was performed and psychotherapy was initiated. A review of the current literature is made and the frequency, clinical characteristics, treatment, management and recommended prophylactic considerations are discussed.

[Postvagotomy complications: stomach bezoars - case report and review of the literature].

A 59 year old female with multiple gastric surgical procedures (Billroth I and Billroth II) for recurring ulcer disease developed a gastric phytobezoar following an additional truncular vagotomy within 2 months. Already 1 month after complete endoscopic removal the phytobezoar recurred in spite of dietary restrictions. The phytobezoar was successfully dissolved by oral Cellulase-therapy. The truncular vagotomy and its influence on gastric motility has to be considered as the cause of the repeated bezoar formation.

Ureteropelvic fungal bezoar causing oliguric renal failure in a premature infant.

Systemic candidiasis with renal involvement is a relatively rare infectious process in young infants. The mortality rate in the cases reported to date has been lower after aggressive surgical and medical management. This report concerns a three-month-old, prematurely born infant with a fatal systemic candidiasis and acute renal failure. Renal pelvic fungal balls caused ureteropelvic junction obstruction in this patient. Renal ultrasonography demonstrated bilateral obstructive uropathy. Treatment consisted of surgical removal of the bezoar, together with open placement of nephrostomy tubes, parenteral amphotericin B therapy and peritoneal dialysis. This case emphasizes the need for a highly suspicion of renal obstruction by fungal balls in any high risk infant with systemic candidiasis and renal dysfunction.

[Gastric bezoars and their complications].

The article discusses four patients who underwent operation for bezoars of the stomach at the Sklifosovsky Scientific Research Institute in a thirty-year period, which testifies to the rarity of the disease. The clinical picture, diagnosis, and the complications of the disease are considered. Special attention is drawn to the surgeon's tactics and the need to inspect the intestine during the operation.

Foreign bodies, bezoars, and caustic ingestion.

Children, particularly infants, frequently put objects into their mouths, and occasionally these objects are swallowed. Fortunately, most foreign bodies are harmless and will pass spontaneously through the gastrointestinal tract. Some foreign bodies such as the rare bezoar or caustic substances, provide unique clinical challenges. This article provides guidelines for the management of such problems.

[Clinico-radiological studies on 3 cases of bezoars].

Three cases of phytobezoar (2 in the stomach and 1 obstructing the ileum) are presented. The bezoar described are due to persimmon in one cases and to applies in two cases and have been observed during a period of over 10 years.

Bezoars and foreign bodies of the stomach.

Bezoars are usually encountered in patients with altered gastric anatomy or function. Symptomatic, large phytobezoars or trichobezoars may require endoscopic fragmentation or surgical removal. Foreign bodies of the stomach are usually a self-limited problem, because at least 90% pass without symptoms, in patients with normal gastrointestinal anatomy. Endoscopic removal should be considered for sharp, pointed, or long objects, or in patients with altered anatomy, such as intestinal stricture.

Neonatal renal failure due to obstructive candidal bezoars.

Acute renal failure (ARF) developed in a 7-week-old infant due to bilateral candidal bezoars (fungal balls) causing obstruction at the pelviureteric junction. The baby was born at term with an appropriate birthweight, and had been treated with broad-spectrum antibiotics for respiratory distress and septicemia during the 1st week of life. Recovery from ARF followed renal decompression with bilateral nephrostomy tube placement and parenteral administration of amphotericin B and 5-flucytosine.

Intragastric balloon as an artificial bezoar for treatment of obesity.

A free-floating rubber balloon was installed as an artificial intragastric bezoar in five obese women. These patients were studied for a total of 272 days - i.e., 130 days with the balloon inflated (10 periods) and 142 days when the balloon was known to be deflated (7 periods). The balloons were easy to insert and reduced hunger. They remained inflated for 7 to 21 days (median 12 days) as judged by radioscopy. Collapsed balloons passed unnoticed with the stools. There were no complications associated with their use. During consecutive periods with balloon, without balloon, and with balloon average weight-losses over 10 days were: 5.0 kg (range 8.6 to 2.0), 0.5 kg (2.9 to 0.3), and 2.1 kg (2.6 to 1.2), respectively. The weight-loss observed while the balloons were inflated is promising but the efficacy of the method can only be evaluated when balloons which remain inflated for several months within the stomach become available.

Neonatal renal candidal bezoar.

Renal candidal bezoar is uncommonly encountered in neonatal intensive care. An affected neonate who improved only after surgical removal of obstructive fungus from the renal pelvis and local irrigation with amphotericin B is described. The need for early consideration of surgical intervention is stressed.

[Pharmacological studies of Reiousan, a drug containing bezoar and ginseng--effects on the blood rheology].

Effects of Reiousan, a crude drug preparation consisting of bezoar and ginseng, on blood rheology were studied. Reiousan improved the deformability of rat erythrocytes exposed to hyperosmorality and treated with phenylhydrazine. The ATP depletion in erythrocytes, the polybrene-induced erythrocyte aggregation and the oxidation of low density lipoprotein were suppressed by Reiousan. Oral administration of Reiousan also improved the erythrocyte deformability in phenylhydrazine-treated rats and delayed the thromboembolic death induced by arachidonic acid in mice. These results suggest that Reiousan has an ameliorative effect on blood rheology related to "Oketsu" syndrome in Kampo diagnostics.

[Determination of cholic acid in man-made bezoar by derivative spectrometry].

Cholic acid in man-made bezoar can be determined by the suggested first order derivative spectrometric method. The peak amplitude within 310-290 nm is independent of the other components and only varies linearly with cholic acid concentration. The method is simple and accurate with good reproducibility.
