Rapunzel syndrome in children: a retrospective review of ten cases combined with literature review in a tertiary referral center

PURPOSE

Rapunzel syndrome is an uncommon condition in children, and its clinical features remain unclear. This study presents the largest single-center series of pediatric cases to date, with the objective of documenting the clinical characteristics and treatment approaches for children with Rapunzel syndrome.

METHODS

A retrospective study was conducted in children with Rapunzel syndrome from 2019 to 2023. We recorded age, gender, symptoms, locations of bezoar, complications, and treatment options.

RESULTS

Ten patients with Rapunzel syndrome were included. The median age was 9.1 years, with all of whom were female. The most common clinical symptoms were upper abdominal mass (90%), abdominal pain (80%), and nausea and vomiting (50%). Complications occurred in six cases (60%), including small bowel obstruction (20%), severe gastric dilatation (10%), intestinal perforation (10%), choledochodilation (10%), acute pancreatitis with cholecystitis (10%). Preoperative ultrasonography suggested low-echoic foreign bodies continuing to the jejunum or ileocecal region in five cases (50%). Preoperative gastroscopy attempted in four cases (40%) to remove the foreign bodies, all of which failed. All patients underwent surgical treatment, with nine cases undergoing gastric incision foreign body removal, and one case undergoing gastric incision foreign body removal combined with intestinal perforation repair. All patients recovered well. No recurrence was observed during follow-up.

CONCLUSION

The accuracy of ultrasound diagnosis in identifying Rapunzel syndrome is high; however, it may lead to misdiagnosis if not complemented with the patient's medical history. Endoscopic presents a heightened treatment risk and a reduced success rate. The condition commonly presents with severe complications, thus making laparotomy a safe and effective option for intervention.

Computed tomographic diagnosis and clinical outcomes of small intestinal obstruction caused by trichobezoars in client-owned rabbits

Small intestinal obstruction in rabbits, although demonstrated to be common, is still poorly characterized. The objective of this study was to report features of small intestinal obstruction caused by trichobezoars in rabbits upon CT and their clinical outcomes. Rabbits with a diagnosis of intestinal obstruction that underwent CT scanning were included in this study. From each CT scan, obstruction location, appearance, Hounsfield units, size (mm), volume (mm3), distance from the stomach, and diameter of the small intestine proximal and distal to it, were extracted. Nine rabbits were included in the study. All rabbits presented for anorexia and had a distended or enlarged stomach (7) or abdomen (2). CT scan showed a non-contrast-enhancing, ovoid, smoothly marginated structure with a hyperattenuating rim, heterogeneous center, and variable amount of centrally located gas, in the duodenum (5), the jejunum (2), or the ileum (2). The density of the trichobezoars ranged from -156 to 58 HU (median, -44 HU) and volume ranged from 86.1 to 633.8 mm3 (median, 320.6 mm3). Three rabbits underwent medical management. Two of them survived, and one of them died. Six rabbits underwent surgery, of which three were successfully discharged from the hospital. CT proved to be a valuable imaging modality in rabbits with a suspected intestinal obstruction to provide the exact location of the obstruction and the characteristics of the obstructive material. The location and size of the trichobezoar may have relevant clinical implications.

Gastrointestinal Bezoars in Paediatrics: Case Series and Literature Review

BACKGROUND

Bezoars are indigestible lumps which are usually found in stomach. Types of bezoar include phytobezoar, trichobezoar, lithobezoar, pharmacobezoar, plasticobezoar, lactobezoar and metal bezoar. Trichobezoars mostly affect females in 20s and 30s with a rarity in paediatrics. Unexplained complaints with a palpable mass are commonly found in these patients. Treatment involves retrieval of mass with searching for others. The purpose of this study was to present data and surgical management of cases with trichobezoars.

MATERIALS AND METHODS

We documented a retrospective review of trichobezoars done in our hospital between 2016 and 2022. All demographic data collected included gender and age of cases, composition and extent of bezoar, clinical presentation, imaging modalities, endoscopic trial, surgical approach and outcome.

RESULTS

Five cases of gastrointestinal tract (GIT) trichobezoars underwent surgery. All cases were females between (13 and 16 years). Trichobezoars were three gastric, one ileal and one of combined gastric and colonic. Complaints were abdominal pain, vomiting, weight loss and halitosis. Three cases had a palpable abdominal mass. Different radiological modalities were performed. Endoscopic retrieval was tried in one patient and the laparoscopic approach in another one, but the first route failed. Laparotomy followed by gastrotomy, enterotomy and colotomy was done without complications.

CONCLUSIONS

Trichobezoars should be suspected in any child with unexplained abdominal complaints or with a palpable abdominal mass, especially in girls. Imaging can be done in different modalities for diagnosis. Endoscopic retrieval could be tried; however, its failure is common, necessitating laparotomy, which has an excellent outcome.

Gastrointestinal trichobezoars in the pediatric population: a retrospective study

BACKGROUND

Trichobezoar is an extremely rare condition characterized by a foreign body in the gastrointestinal tract (GIT) among children. The foreign body may exist in the digestive tract for several years, and it becomes evident if complications develop. The current study aimed to present 21 cases of GIT trichobezoars.

METHODS

Retrospective analysis of children who were diagnosed with trichobezoars between August 2012 and December 2022. Patient demographics, clinical presentation, diagnosis, and therapy were collected and analyzed.Twenty-one patients had GIT trichobezoars. Data were collected and analyzed retrospectively.

RESULTS

Twenty-one patients were identified. All patients were female. Their mean age at admission was 8.9 ± 1.9 years. Furthermore, 19 (90.5%) patients presented with abdominal pain, 16 (76.2%) with vomiting, and 13 (61.9%) with a palpable mass. Sixteen patients underwent gastroduodenoscopy. Among them, 15 had gastric trichobezoars. Moreover, 12 patients underwent computed tomography scan. Eight patients presented with gastric and small intestinal BZs, one presented with increased small intestinal contents with dilation, and one presented with abundant gastric contents. Then, 20 patients underwent surgery. Among them, five underwent laparoscopic-assisted minilaparotomy (LAML), and the rest underwent laparotomy. The results showed that 10 (50%) patients had gastric trichobezoars; 7 (35%), Rapunzel syndrome; and 3 (15%), small bowel trichobezoars. Two patients developed superficial wound infection postoperatively. One patient had a recurrent gastric trichobezoar.

CONCLUSION

Trichobezoar should be considered in young girls with a history of hair eating or those with hair in the vomit or feces. Timely diagnosis and aggressive treatment are the keys to reducing complications and improving prognosis. Laparoscopic-assisted minilaparotomy is a safe, feasible, and effective surgical method for treating trichobezoars.

A case of Rapunzel syndrome

Rapunzel syndrome is a rare disorder characterized by a trichobezoar in the gastroduodenal tract caused by trichophagia. Diagnosis was confirmed by upper endoscopy and treatment was surgical.

Expect the unexpected: bezoar-caused gastric perforation in the 19-year-old patient, after traffic accident

A 19-year-old female involved in a traffic accident presented to the Emergency Room (ER) with no trauma-related symptoms but a palpable mass in the epigastrium. Imaging revealed a massive trichobezoar causing gastric perforation. Urgent laparotomy was performed, and a 1.5-kilogram bezoar was removed, along with repairing coexisting gastric ulcers. The patient had a history of trichophagia, suggesting a psychiatric association. This case highlights the potential of trichobezoars to cause gastric perforation, even in patients admitted for unrelated reasons. CT-scan proves effective in diagnosing such cases. While a traffic accident might be a plausible cause, the presence of a bezoar can elevate the risk of complications. Psychiatric evaluation is recommended when trichophagia is identified. The study underscores the need for vigilance in unexpected scenarios, demonstrating the importance of multidisciplinary approaches in managing such cases.

Point-of-Care Ultrasound of a Pediatric Gastric Trichobezoar: A Case Report

ABSTRACT

This case report describes a previously healthy pediatric patient with acute onset of abdominal pain and distention who was found to have an epigastric mass on physical examination. Point-of-care ultrasound (POCUS) demonstrated a large gastric mass with ultrasonographic features consistent with a trichobezoar. After POCUS was performed, trichophagia was confirmed on history, and the patient went to the operating room for removal of a large trichobezoar. We conclude POCUS may be helpful for evaluation of epigastric masses and diagnosis of gastric trichobezoars. We review the ultrasound technique, sonographic findings, and literature regarding ultrasound diagnosis of trichobezoars.

A rare cause of intestinal obstruction in children trichobezoar: How to diagnose?

BACKGROUND

Trichobezoar is a rare clinical condition in children, which is caused by the accumulation of swallowed hair mass in the digestive tract. This condition is most common in young women with psychiatric histories who suffer from trichotillomania (TTM), where they have an irresistible urge to pull out their hair. Diagnosis and treatment of this pathology, which is already extremely rare, and its variable clinical presentations are challenging. The aim of this study was to increase awareness of trichobezoar in the differential diagnosis of signs of intestinal obstruction in children and to evaluate the diagnosis and management of this rare pathology.

METHODS

The clinical data of six patients who were treated for trichobezoars in the pediatric surgery department of our hospital between 2009 and 2022 were retrospectively analyzed.

RESULTS

Six female patients were treated with the diagnosis of trichobezoar during this period. Patients were diagnosed with the help of anamnesis, physical examination, abdominal ultrasonography (USG), and finally, endoscopy. USG can predict the intestinal wall infiltration and the tail extended to the duodenum through pylorus in the series. All patients were evaluated with contrast-enhanced abdominal radiography. Five surgical interventions were performed in four of the cases. In a case who underwent surgery twice, the distal intestinal satellite bezoar was not noticed in the first operation. Two patients were diagnosed to have trichobezoar, but surgery was not required. These patients were younger and had early-onset TTM (before 10 years old). The patients were followed for an average of 10.8 years and no recurrence was detected.

CONCLUSION

Trichobezoar is a rare cause of intestinal obstruction in children with fatal complications when diagnosed late. Failure to follow an algorithm for the management of the disease causes difficulties in the diagnosis and treatment. Especially in pa-tients with a known psychiatric history, whole abdominal USG and laparoscopy performed with awareness can prevent unnecessary examinations.

Intestinal Obstruction Due to Reassembly after Endoscopic Crushing of a Bezoar

An 87-year-old woman visited her primary-care doctor because of nausea and epigastric pain. Esophagogastroduodenoscopy (EGD) revealed a giant bezoar in her stomach. She was referred to our hospital after carbonated beverage dissolution proved ineffective and underwent endoscopic mechanical crushing. After crushing, the symptoms disappeared, and she began eating. Later, however, the crushed fragments reassembled in the duodenal bulb and caused intestinal obstruction. The patient underwent emergency EGD for crushing once more, and all of the fragments were extracted from the body. This case highlights the need for bezoars to be removed from the body after crushing in order to avoid reassembly.

Small bowel obstruction secondary to phytobezoar in a patient with myotonic dystrophy

A male patient in his 30s, with myotonic dystrophy (DM), presented to the emergency department with abdominal pain and vomiting. CT imaging revealed a soft tissue lesion in the terminal ileum causing small bowel obstruction (SBO). The patient underwent diagnostic laparoscopy which allowed identification and removal of the obstructing lesion. This was in the form of an intact, undigested potato, a phytobezoar. Bezoars are collections of undigested material found in the gastrointestinal (GI) tract, a phytobezoar is composed of plant material and is the most common form of bezoar. DM is a multisystem disorder characterised by skeletal muscle weakness, however it often presents with GI symptoms and the muscles of mastication are often affected. DM is a known risk factor for bezoar formation and should be considered as an important differential in DM patients presenting with SBO.

Evaluation of the location, number and diameter of bezoars in patients with a history of previous gastrointestinal surgery

OBJECTIVE

Bezoars are foreign bodies developed due to the swallowing of indigestible substances in the stomach that accumulate in the lumen of the gastrointestinal tract. This study aimed to compare the location, size, and diameter of bezoars between patients with and without a history of previous gastrointestinal surgery and between operated and non-operated patients retrospectively.

METHODS

A total of 188 patients who presented to our gastroenterology clinic and in whom bezoar was suspected on clinical examination and the diagnosis confirmed through abdominal CT scans were included in the study. The patients were divided into two groups; patients with a history of previous gastrointestinal surgery were assigned to Group 1 (n = 70), and those who had no history of previous surgery (n = 118) to Group 2.

RESULTS

The mean age was found as 56.16 ± 15.75 years in Group 1 and 57.71 ± 15.95 years in Group 2. The mean bezoar width was significantly higher in Group 1 (p = 0.049). The mean bezoar length was significantly higher in Group 1 (p = 0.004). Considering localization of bezoars, the rate of patients who underwent enterotomy (80%) was statistically significantly higher than the patients who underwent gastrotomy (23.50%), gastrotomy + milking (28.60%) and milking (44.70%) in the operations performed in the jejunum.

CONCLUSION

Bezoars are a rare cause of intestinal obstruction. The median width and length of the bezoars were significantly higher in patients with a history of previous gastric surgery. There was no significant difference in other parameters. The most common localization was jejunum.

[Rapunzel syndrome: Radiological diagnosis]

Background

Rapunzel syndrome is a rare presentation of trichobezoar, secondary to the ingestion of hair known as trichophagia. This bezoar has been found mainly in women, it invades the stomach and extends to the small intestine. Clinically, patients present weight loss and chronic obstructive symptoms at the intestinal level. A case of Rapunzel syndrome is presented.

Clinical case

A 13-year-old female presented with a weight loss of 10kg in two months, chronic constipation, predominantly nocturnal vomiting, and abdominal pain of seven days' duration. Physical examination revealed decreased peristalsis and a palpable mass in the epigastrium. Laboratories taken on admission: normal blood count, kidney function tests, and liver function tests. The abdominal X-ray showed opacity in the fundus, body and gastric antrum, the abdominal ultrasound showed non-specific findings in the epigastrium, later an abdominal tomography was performed with a swallow of water-soluble contrast medium and showed occupation in the gastric lumen. She underwent exploratory laparotomy and the finding was a trichobezoar in the stomach with extension to the duodenum and part of the jejunum, which was removed without complications. The evolution of the patient was favorable.

Conclusions

For the diagnosis of Rapunzel Syndrome, the use of contrast imaging studies is necessary, and the treatment of choice is surgical.

Treatment of large gastric trichobezoar in children: Two case reports and literature review

RATIONALE

Gastric trichobezoars are a rare form of bezoar formed from swallowed human hair as well as hair from dolls or animals, blankets, and carpets. They usually develop in young women who are emotionally disturbed, depressed, or mentally retarded, with trichotillomania and trichophagia. They can lead to abdominal pain, gastric ulceration, bleeding, obstruction, and perforation.

PATIENT CONCERNS

A 13-year-old girl was admitted to our institution with complaints of nausea, vomiting, and epigastric pain for 2 days. She underwent laparoscopic removal of a large gastric trichobezoar at our institution 5 years ago. A 12-year-old girl presented at our institution due to epigastric pain, dizziness, and melena for 2 days.

DIAGNOSIS

They were diagnosed with gastric trichobezoar by abdominal computed tomography scan and upper gastrointestinal endoscopy.

INTERVENTIONS

Large gastric trichobezoars were removed via a mini-laparotomy.

OUTCOMES

They recovered well postoperatively without complication.

LESSONS

Although the recurrence of gastric trichobezoar after surgery is rare, few recurrent cases were reported in the literature. Therefore, psychiatric consultation and regular follow-up after treatment should be considered in the children and their parents to prevent the recurrence of gastric trichobezoar.

Trichobezoar-A rare cause of hyperemesis in a pregnant woman

Bezoars consist of ingested foreign material or organic matter which forms a mass in the gastrointestinal tract, usually in the stomach. Trichobezoars formed by swallowed hair may present with vomiting, malnutrition, weight loss or abdominal pain with signs of gastrointestinal obstruction. There are limited case reports of Trichobezoar during pregnancy. We present a case of young pregnant women who was admitted on few occasions with vomiting in early pregnancy and was treated as hyperemesis gravidarum. Failure of response to conventional management prompted further investigation, revealing trichobezoar. Our case highlights the diagnostic challenge posed by trichobezoars in young pregnant women.

An Unusual Small Bowel Phytobezoar Successfully Resolved by Double-balloon Enteroscopy

We herein report a very unusual case of small bowel obstruction caused by phytobezoar in a 69-year-old woman who consumed a large amount of bracken. The patient presented with nausea and vomiting. Computed tomography revealed an air-filled foreign body in the jejunum that had likely caused the small bowel obstruction. A fibrous foreign body diagnosed as a phytobezoar was detected using double-balloon enteroscopy. The obstruction was successfully resolved by crushing the phytobezoar repeatedly using a snare. Small bowel obstructions caused by phytobezoars are often treated with surgical interventions. However, endoscopic fragmentation using a snare is a minimally invasive treatment alternative.

Small bowel obstruction secondary to a plastic bezoar

We present a case of a small bowel obstruction secondary to a rare plastic bezoar. A man in their early 20s with autism and an intellectual disability presented with symptoms of small bowel obstruction. CT revealed very subtle signs and, despite passage of gastrografin, ongoing clinical suspicion led to operative management which confirmed the diagnoses of plastic bezoar.

Small bowel obstruction secondary to crab shell bezoar: A case report

Small bowel obstruction is a common surgical condition that needs surgical intervention if conservative measures fail. Bezoar is a rare aetiology of small bowel obstruction with incidence of 4.5%. The bezoars can be grouped, according to the content, into four common types: phytobezoars, trichobezoars, pharmacobezoars, and lactobezoars. However, unusual bezoars like plastic bezoars and metal bezoars have been reported too. Herein, we report a case of an elderly lady who was treated for small bowel obstruction due to crab shell bezoar. This is the first case reported in literature. Ingestion of large intact pieces of crab shell should be avoided due to the potential of causing small bowel obstruction.

Tannin-phytobezoars with Gastric Outlet Obstruction Treated by Dissolution with Administration and Endoscopic Injection of Coca-Cola®, Endoscopic Crushing, and Removal (with Video)

A 77-year-old man complained of postmeal vomiting and sustained general fatigue. An abdominal computed tomography scan showed massive gastric expansion and fluid storage. Gastroscopy revealed four gastric bezoars that were considered to have caused pyloric ring obstruction. The patient was asked to drink 500 mL per day of Coca-Cola^® for 4 days. On the fourth day, we performed endoscopic crushing and removal by injecting Coca-Cola^®, cutting the softened bezoar with endoscopic snares, and collecting the pieces with endoscopic nets. We herein report (with a video presentation) a rare case of tannin-phytobezoars endoscopically removed with the administration and injection of Coca-Cola^®.

Gastric perforation secondary to Rapunzel syndrome

Rapunzel syndrome is rare and describes a trichobezoar that extends through the pylorus into the jejunum, ileum or even the colon. Due to the large intraluminal size and weight they can attain, acute presentations of obstruction or perforation may occur. We report a case of a 17-year-old girl who presented to the emergency department following a syncopal episode. On examination, a left upper quadrant mass was appreciated with no signs of peritonism. Contrast-enhanced CT demonstrated a giant trichobezoar with resulting gastric perforation and intra-abdominal free fluid. Laparotomy and gastrotomy were performed and the patient had an uneventful recovery with psychiatric review prior to discharge. Though uncommon, bezoars should be included in our differential diagnosis as they can present in various ways owing to their size and weight. This case illustrates the risk of gastric perforation with large gastric bezoars.

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.

Trichobezoar

BACKGROUND

Rapunzel syndrome refers to a gastric bezoar with post-pyloric extension.

CASE PRESENTATION

A child of primary school age presented with four days of abdominal pain, nausea, vomiting and a non-tender palpable mass in the upper part of the abdomen. The child had a history of trichotillomania and trichotillophagia. Preoperative imaging including abdominal ultrasound and upper gastrointestinal series was suggestive of gastric bezoar extending into the duodenum. At laparotomy and gastrotomy a large trichobezoar which had taken the shape of the stomach with a 60 cm long tail extending into the jejunum was removed. The child had an uneventful recovery and was discharged home on the fifth postoperative day.

INTERPRETATION

Although rare, trichobezoar should be considered as a differential diagnosis for abdominal pain in young patients with a known history of trichotillomania and trichotillophagia.

Multiple small bowel perforation in a young adult female due to Rapunzel Syndrome

INTRODUCTION

Rapunzel's syndrome is the state of the gastric trichobezoar (hair ball) extending to the small intestine. Although it is seen very rarely, it is a psychiatric and mental illness especially in young women. We present here, a young female with recurrent trichotillomania.

CASE PRESENTATION

In a 24-year-old patient who underwent laparotomy due to recurrent trichobezoar, which completely filled the stomach and extended to the small intestine, caused perforation in two places in the small intestine, was removed by gastrotomy and enterotomy. One of the perforated areas was very close to ligament of Treitz, and perforation occurred due to the ulcer caused by trichobezoar. Post-operative central total parenteral nutrition was given and oral intake was started at the end of the first week. The patient was referred to psychiatry and antipsychotic medication was started. She was discharged on the 9th postoperative day without any problem.

CONCLUSION

Although there are no signs of peritonitis in such Rapunzel syndrome cases, a detailed exploration should be made by keeping in mind that trichobezoar will cause ulceration and perforation. In addition, as the primary cause is the underlying psychiatric disorder, patients should be referred to the psychiatry clinic to prevent recurrence.

KEY WORDS

Adult, Rapunzel syndrome, Surgery, Trichobezoar, Trichotillomania.

The cause of abdominal mass in a child with celiac disease: Rapunzel syndrome. A case report

CONTEXT

Rapunzel syndrome is a rare form of gastric trichobezoar that develops through outstretching of the bezoar from the stomach to the intestine.

CASE REPORT

A 12-year-old girl who had been diagnosed with celiac disease six years earlier was brought to the department of pediatric gastroenterology because of abdominal distension. A palpable mass was detected. A trichobezoar that stretched to the small intestine was removed surgically. The patient was diagnosed as having anxiety and depressive disorder, and treatment started. Following the treatment, her previous trichophagia completely disappeared.

CONCLUSION

Presence of trichobezoar should be kept in mind, especially when young girls who have psychiatric problems suffer from gastrointestinal symptoms.

[Giant Rapunzel syndrome with atypical complication. Report of a case]

Rapunzel syndrome is an unusual and rare form of gastric trichobezoar that extends into the small intestine. The formation is due to the continuous ingestion of hair which leads to the impaction of the hair along with mucus and food, but it is rare that gastric perforation occurs. We report the case of a female patient of 16 years of age admitted to our institution with a history of depression and clinical symptoms characterized by nausea, severe epigastralgia and pathological loss of weight. The physical examination showed a tense abdomen with a peritoneal reaction. Contrast-enhanced tomography showed a distended stomach with a heterogeneous content that extended to the duodenum, hydro pneumoperitoneum, Douglas sack bottom liquid, and it was decided to perform an exploratory laparotomy. Showed perforation in the anterior face of the stomach which is infrequent, so we proceeded to the extraction of giant trichobezoar with duodenal extension; Evolving favorably, the patient being referred to outpatient controls with psychiatry; Finally, a high endoscopy was performed at 6 months, which evidenced the scar of the surgical procedure.

Fungaemia caused by obstructive renal candida bezoars leads to bilateral chorioretinitis: a case report

BACKGROUND

Renal fungal bezoars are remarkably rare and mostly occur in immunodeficient patients. Only a small number of cases with immunocompetent patients have been published so far. The published treatment approaches comprised systemic antimycotic therapy and surgical or minimal invasive removal of the fungal balls. In some cases irrigation of the renal duct system with amphotericin B was performed. By obstruction of the urinary tract bezoars can lead to infected hydronephrosis and severe urosepsis with high lethality. Fungaemia can cause fungal colonization in different distant organs. Fulminant chorioretinitis and irreversible visual impairment can be the consequence of ocular fundus colonization. The following report highlights that a co-operation between urologists and ophthalmologists is absolutely indispensible in case of fungaemia.

CASE PRESENTATION

Hereinafter we describe a case of an immunocompetent 56 years old woman, presenting with flank pain and shivering. The diagnosis turned out to be difficult due to initially negative urine culture. The fungaemia caused by obstructive nephropathy led to bilateral candida chorioretinitis. The patient was treated with intravenous amphotericin b and the bezoar was removed by percutaneous "nephrolitholapaxy". After two months, a follow up revealed the patient felt well, chorioretinal lesions regressed and urine culture did not show any fungal growth.

CONCLUSION

To the best of our knowledge, this is the first case reporting on obstructive renal bezoars, which lead to haematogenous fungus spread and bilateral chorioretinitis. It points out that extensive ophthalmologic examination should be performed in case of fungaemia even if the patient is not suffering from any visual impairment.

An unusual enterolith ileus

The duodenum is an uncommon location of diverticula in the digestive tract, and they are often asymptomatic. Formation of an enterolith inside diverticula has been previously described, although it is a rare condition. In this context, intestinal obstruction due to distal migration of foreign bodies is extremely rare. We report a case of an 86-year-old woman with obstructive symptoms due to a jejunal foreign body that had migrated from a duodenal diverticulum. An emergency laparotomy was performed to extract a phytobezoar. Enterolith ileus secondary to duodenal diverticula is an exceptional entity. Diagnosis and management are usually delayed because of a non-specific presentation, and early surgical exploration is required for bowel disimpaction. This condition should be considered in elderly patients with prolonged immobilization or neurodegenerative diseases.

Delayed diagnosis of trichobezoar in a patient with presumed anorexia nervosa

Anorexia nervosa is a medical and psychological disorder classically seen in young women who present with significant weight loss, a distorted body image, and an intense fear of gaining weight despite being underweight. A rare diagnosis that is also associated with weight loss is a trichobezoar, a collection of hair or hair-like fibers in the gastrointestinal tract, primarily in the stomach. In this report, we present the case of a 14.5-year-old girl with weight loss caused by a trichobezoar, initially thought to be due to anorexia nervosa, and we review the details of both disorders.

Gastric Outlet Obstruction--An Unexpected Complication during Coca-Cola Therapy for a Gastric Bezoar: A Case Report and Literature Review

Gastric bezoars are concretions of undigested material, and Coca-Cola therapy is an easy, efficacious and safe approach for bezoar treatment. Gastric outlet obstruction due to a migratory gastric bezoar during Coca-Cola therapy is an uncommon presentation and, to the best of our knowledge, no cases have been previously reported. We herein describe one such case with no known predisposing factors that recovered via the endoscopic technique. A thorough literature search was performed, which yielded eight relevant patients from seven publications, all of who developed gastrointestinal obstruction during dissolution treatment and recovered uneventfully after surgical intervention. In conclusion, this potential complication should be kept in mind in the event that alternative treatment is necessary.

Bezoar-induced small bowel obstruction: Clinical characteristics and diagnostic value of multi-slice spiral computed tomography

AIM: To determine the possible predisposing factors of bezoar-induced small bowel obstruction (BI-SBO) and to discuss the diagnostic value of multi-slice spiral computed tomography, particularly contrast-enhanced scanning, in this condition.

METHODS: A total of 35 BI-SBO cases treated at our hospital from January 2007 to December 2013 were retrospectively analysed. Complete clinical and computed tomography (CT) data of the patients were available and confirmed by surgery. SBO was clinically diagnosed on the basis of clinical manifestations. Of the 35 patients, 18 underwent abdominal and pelvic CT planar scanning with GE 64-slice spiral CT and 17 underwent abdominal and pelvic CT planar scanning with GE 64-slice spiral CT combined with contrast-enhanced examination. Original images were processed using a GE ADW4.3 workstation to obtain MPR, CPR, MIP and CTA images. The images of all patients were evaluated by two abdominal imaging experts. The main analytical contents of planar scanning included intestinal bezoar conditions, changes in the intestinal wall and changes in peri-intestinal conditions. Vascular hyperaemia and arterial blood supply conditions at a specific obstruction site and the distal end of the obstruction site were evaluated through contrast-enhanced examination.

RESULTS: The proportion of males to females among the 35 cases was 1:1.69 (13:22); median age was 63.3 years. The following cases were observed: 29 (82.8%) cases occurred in autumn and winter and showed a history of consuming high amounts of persimmon and hawthorn; 19 (54.3%) cases revealed a history of gastrointestinal surgery; 19 exhibited incomplete dentition, with missing partial or whole posterior teeth; 26 suffered from obstruction at the ileum. A total of 51 bezoars were found in these patients, of whom 16 (45.7%) had multiple bezoars. CT planar scanning of bezoars showed lumps with mottled gas inside the intestinal cavity. Furthermore, 9 cases of bezoars had envelopes and 11 cases were accompanied with thickening of the distal wall of the obstructed bowel. Scanning of 17 cases was enhanced; the results revealed that the mesenteric blood vessels at the obstruction site and the proximal site were dilated, and a total of 7 cases were accompanied with distal vascular dilation and intestinal wall thickening.

CONCLUSION: BI-SBO exhibits regional and seasonal characteristics. CT planar and contrast-enhanced scanning can be applied to diagnose and observe vascular conditions in obstructed zones.

RECTAL IMPACTION DUE TO PRICKLY PEAR SEEDS BEZOAR: A CASE REPORT

Fecal impaction is the third cause of lower gastrointestinal tract obstruction after strictures for colon cancer and postoperative adhesions. A rapid diagnosis is necessary to avoid complications due to intestinal obstruction. Rectal phytobezoar due to prickly pear fruit seeds are an extremely rare entity, in the literature about twenty similar cases are described. Prickly pears are common in many countries, even in the Mediterranean area. When the ingestion of their fruit is excessive, this can be harmful, leading to the formation of phytobezoar causing fecal impaction. We describe the first case of phytobezoar due to prickly pear fruit seeds in continental Europe: a 76-year-old Italian female who ingested almost 40 prickly pear fruit leading to the composition of a large rectal phytobezoar. The patient presented clinically with fecal impaction, diagnosed by imaging and successfully treated by rectal irrigation and manual disimpaction. Our aim is to remind the physicians of these risks in evaluating patients with intestinal obstruction, when there is positive anamnesis for provenience from some areas in which these fruits are eaten. We also want to underline the role of Imaging Multi Detector Computed Tomography (MDCT) in the diagnosis of these very uncommon entities.
