Vesical fungal bezoars on post-TURBT scar tissue causing obstruction and mimicking urothelial carcinoma.

Fungal bezoars (fungal balls) are rarely reported in the upper or lower urinary tract. They can be the cause of severe morbidities such as urinary tract obstruction, renal failure and fungaemia. Hereby, we present a rare case of a male patient who underwent transurethral resection of bladder tumour (TURBT), and during his postoperative period, he was diagnosed with bladder fungal bezoars adherent to his resection area. The fungal bezoars were covering an extended area of the right lateral bladder wall, including the right ureteric orifice and causing right urinary tract obstruction. Those findings were manifested only after a relooked cystoscopy and histological evaluation.We aim to present a rare example of fungal bezoars mimicking other pathologies in the urinary tract and review the current literature for similar documentation. We underline the necessity of follow-up examinations for urologists performing TURBT surgeries, including urinalysis, imaging modalities and cystoscopy.

Gastrointestinal (GI) bezoars are aggregates of undigested material found in the GI tract. Trichobezoar is the most common type of bezoars and consists of ingested hair, carpet fibers or fitted carpet fibers. They are mainly located in the gastric region, rare forms extend to the duodenum or small intestine and are described as Rapunzel syndrome. Typical CT imaging features play a diagnostic and prognostic role. We report the case of a 13-year-old girl hospitalized for occlusive syndrome due to trichobezoar.

Ileal Ulcer Associated With a Large Bezoar Mimicking Malignancy on FDG PET/CT.

A 34-year-old woman presented with abdominal pain for 2 months. Abdominal CT revealed a large bezoar in the distal ileum with surrounding thickened ileal wall and enlarged mesentery lymph nodes. On FDG PET/CT, the thickened ileal wall and enlarged mesentery lymph nodes showed increased FDG uptake. Ileal malignancy with mesentery lymph node metastasis was suspected. The distal ileum and enlarged mesentery lymph nodes were removed. Benign ileal ulcer and mesentery reactive lymphoid hyperplasia were confirmed by histopathology.

Massive Bezoar in a Free-Ranging South African Oryx (Oryx gazella gazella) in South-Central New Mexico, USA.

We documented a 23 kg bezoar that filled >60% of the rumen of an adult oryx (Oryx gazella gazella) harvested in New Mexico, US. The nidus of the bezoar was comprised of nylon cords and parachute cloth, constituents of parachutes. Although slightly thin, the oryx was otherwise healthy at harvest.

Formation of a temporary gastrostomy to aid delivery of gastric trichobezoar and decrease incidence of wound infection.

Trichobezoars are relatively uncommon problems with a known female predominance. We report two female children with gastric bezoars. Main presenting symptoms were abdominal distension, weight loss and anaemia. Upper abdominal mass was palpable in both. Diagnosis was suspected on initial abdominal radiograph and ultrasound scan then confirmed by upper endoscopy. No bowel extension was recorded in either case. We report here a modification of the surgical technique in which the gastrostomy cut edges were anchored to the laparotomy skin. This modification aided easy and complete delivery of hair balls avoiding any spillage or wound contamination.

Tricobezoar de estómago / Gastric Trichobezoar Rapunzel Syndrome

Trichobezoars are an unusual pathology that appears generally in young adolescents associated with psychiatric disorders. The clinical presentation is very varied. The diagnosis is suspected by the clinical records of teen agers with trichophagia and trichotillomania and the digestive disorders are confirmed by the results of the endoscopy, the same as with images toward the therapeutic management. Undowbtly the treatment is surgical, and continuation with the psychiatric treatment is essential to avoid a recidival of the disease. Bezoar is a concretion formed in the alimentary tract, and according to the substances forming the ball, we find trichobezoar (foodball). The Rapunzel syndrome is an unusual complication of individual bezoar. When the trichobezoar located in the stomach extends through the pylorus into the small intestine and the right colon, is known as Rapunzel syndrome, that is an extremely rare gastric condition in humans. It is a rare form of trichobezoar, occurring in psychiatric patients with the trichobezoar (hairball) located in the stomach. The syndrome is named after the long haired girl Rapunzel in the fairy tale of the brothers Grimm. Most bezoars in teen agers are trichobezoars from swallowed hair. A 28-year-old patient is presented, with abdominal pain and vomiting, on the general physical examination the patient revealed a severe weight loss. Later on, through a gastrostomy, appeared the trichobezoar, being removed with good postsurgical resullts

Endoscopic removal of a gastric pharmacobezoar induced by clomipramine, lorazepam, and domperidone overdose: a case report.

INTRODUCTION: Gastric pharmacobezoars are a rare entity that can induce mechanical gastric outlet obstructions and sometimes prolong toxic pharmacological effects. Certain medications, such as sustained-release forms, contain cellulose derivatives that may contribute to the adhesion between pills and lead to the creation of an aggregate resulting in a pharmacobezoar. Case reports are rare, and official guidelines are needed to help medical teams choose proper treatment options. CASE PRESENTATION: Our patient was a 40-year-old Caucasian woman with borderline personality disorder and active suicidal thoughts who was found unconscious after a massive drug consumption of slow-release clomipramine, lorazepam, and domperidone. On her arrival in the emergency room, endotracheal intubation was preformed to protect her airway, and a chest x-ray revealed multiple coffee grain-sized opaque masses in the stomach. She was treated with activated charcoal followed by two endoscopic gastric decontaminations 12 h apart in order to extract a massive gastric pharmacobezoar by manual removal of the tablets. CONCLUSION: This case demonstrates that in the case of a massive drug consumption, a pharmacobezoar should be suspected, particularly when cellulose-coated pills are ingested. Severe poisoning due to delayed drug release from the gastric aggregate is a potential complication. Detection by x-ray is crucial, and treatment is centered on removal of the aggregate. The technique of decontamination varies among experts, and no formal recommendations exist to date. It seems reasonable that endoscopic evaluation should be performed in order to determine the appropriate technique of decontamination. Care should be patient-oriented and take into account the clinical presentation and any organ failure, and it should not be determined solely by the suspected medication ingested. Thus, serum levels are not sufficient to guide management of tricyclic antidepressant intoxication.

Rapunzel syndrome in adult with mysterious presentation: a rare case report with literature review.

Bezoars are indigestible foreign material in the gastrointestinal tract (GIT). A phytobezoar is a mass of plant material, while a trichobezoar consists of matted hair. This is found most commonly in the stomach in children who chew their long hair. When a gastric trichobezoar extends to the duodenum or jejunum, this is known as Rapunzel syndrome (RS), after a famous Brothers' Grimm fairy tale. Our patient presented with haematemesis, localised peritonitis, a palpable epigastric mass, coagulopathy, severe anaemia and deranged liver function tests. An abdominal computed tomography scan was suggestive of a bezoar; gastroduodenoscopy confirmed the diagnosis. Treatment of trichobezoars normally involve endoscopic removal or gastrotomy and psychiatric intervention. They may also cause haematemesis, gastric outlet obstruction, gastric ulceration and perforation, multiple jejuno-jejunal intussusception, acute pancreatitis and cholestatic jaundice. Trichobezoar was first reported in the 18th century by Baudamant in a 16-year-old boy. RS was first described in 1968.

Rapunzel syndrome (gastric trichobezoar), a rare presentation with generalised oedema: case report and review of the literature.

Rapunzel syndrome is a rare form of gastric trichobezoar. A 4-year-old girl presented with generalised oedema and an epigastric mass. Her family was of a relatively low socio-economic background. There was microcytic hypochromic anaemia, hypoalbuminaemia and an elevated α1-antitrypsin clearance. Abdominal ultrasound and non-contrast computed tomography demonstrated a heterogeneous mass related to the stomach. Upper gastro-intestinal tract endoscopy failed to remove it. Surgical laparotomy was undertaken through a single anterior gastrotomy incision and a large mass was extracted which was a cast of the duodenum and stomach and had a tail of approximately 60 cm in length which extended to the jejunum. Low socio-economic status, child neglect and pica are risk factors for trichobezoars. Surgical laparotomy is the optimal treatment of large bezoars.

When a cure becomes the pathology: mechanical bowel obstruction due to herbal pharmacobezoar. A case report with review of literature.

Bezoars are intra-luminal concretions of ingested material which accumulate within the bowel. They are termed pharmacobezoars when the constituent material is drugs. We report a 64-year-old female with abdominal pain and obstipation for 3 days. Patient had completed anti-tuberculous combination therapy for suspected abdominal tuberculosis 25 years ago. She exhibited features of shock with a right iliac fossa lump. Abdominal X-ray displayed multiple air-fluid levels with densely cluttered radio-opacities in the right lower quadrant. Laparotomy revealed a palpable mid-ileal intra-luminal lump, adherent to the ascending colon and proximal ileum necessitating resection. Ex vivo examination of resected specimen revealed numerous tablets aggregating proximal to an ileal stricture. The patient post-operatively confirmed the tablets resembled the herbal laxatives she had been consuming. Pharmacobezoars can lead to subacute intestinal obstruction. Numerous drugs have been implicated. Patients with partial gastrectomy and vagotomy are at risk. CT is the pre-eminent diagnostic modality. The treatment options for pharmacobezoars include lavage, endoscopic retrieval, in addition to surgery. Pharmacobezoars need a high index of suspicion for pre-operative diagnosis. A detailed history and correlation with radioimaging can offer important cues. One can prevent pharmacobezoars by abstaining from unwarranted medications and identifying those at risk.

A Rare Case of Fatal Bowel Obstruction Secondary to a Colonic Bezoar.

A bezoar is a mass of undigested, or partially digested, material forming in the lumen of the gastroenteric tract, causing occlusive or subocclusive events. The most frequent types of bezoars are those composed of vegetable fibers, also called phytobezoars, which, by virtue of their high content in cellulose, hemicellulose, and lignin, remain undigested in the stomach and intestines and, from there, can migrate and occlude the narrowest portions of the bowel. The areas that are most frequently affected by occlusive phenomena related to the presence of bezoars are the stomach and the small intestine, although colic localizations are extremely rare. In this article, we have studied the case of a fatal colic obstruction caused by a phytobezoar in an 84-year-old woman who was found dead at her home. The autopsy revealed that the cause of the obstruction was a large artichoke fragment occluding the central part of the descending colon. Additional histological examinations confirmed that the death was attributable to bowel obstruction resulting in acute peritonitis.

Osteoid bezoar: a rare case causing small bowel obstruction.

Acute intestinal obstruction due to foreign bodies or bezoar is a rare occurrence in an adult. We report an unusual case of a 27-year-old male patient with no previous history of abdominal surgery or other medical disease, who presented with an acute episode of intestinal obstruction due to ingestion of a bone piece which was managed surgically by enterotomy, and the patient had an uneventful postoperative course. He was advised regular follow-up once in 2 weeks initially and once a month subsequently. He had no problems at the end of 6 months.

Giant gastric trichobezoar in a young female with Rapunzel syndrome: case report.

Rapunzel syndrome is an extremely rare complication of a gastric trichobezoar in. We report here the unusual case of a case of a 16 years old girl presented with severe abdominal pain and vomiting. Clinical examination revealed a malnourished girl, with presence of a mobile and sensitive abdominal mass of 20x15 cm witch filled the upper quadrant. An abdominal computed tomography scan showed a heterogeneous mass occupying the whole stomach cavity with extension into the third portion of the duodenum. A diagnostic of giant trichobezoar is suspected after further questioning reveling a trichotillomania, trichophagia and onychophagia. The removal of the trichobezoar endoscopically failed and it was possible to pull only few fibers of hair to comfort the diagnostic. She was subjected to an exploratory laparotomy. An antral gastrostomy were performed and a 25x10x7 cm trichobezoar was extracted. The patient had an uneventful postoperative outcome and was derived to psychiatry. Rapunzel syndrome is an uncommon trichobezoar, it's commonly found in young females usually with an underlying psychiatric disorder. Management requires gastrotomy. A psychiatric assessment and a long-term follow-up are advocated as a regular part of treatment to prevent recurrence.

Importance of Second-look Endoscopy on an Empty Stomach for Finding Gastric Bezoars in Patients with Gastric Ulcers.

　Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.
