Laparoscopic removal of massive pediatric gastric trichobezoars: A brief report

Small-bowel trichobezoars with intestinal obstruction in children: three case reports and literature review

Trichobezoars are conglomerates of hair within the gastro-intestinal tract, commonly detected in the stomach, and they can present with the Rapunzel syndrome. Isolated small-bowel trichobezoars are extremely rare. Three female patients presented with abdominal pain and bilious vomiting, and underwent various imaging examinations. Two were diagnosed with small-bowel trichobezoars with intestinal obstruction and one with intestinal obstruction only. All three underwent surgery. Two underwent laparoscopic exploration and one underwent a laparotomy. One and two patients had isolated small-bowel trichobezoars in the ileum and jejunum, respectively. Two patients were followed up by a psychiatrist, and all recovered well without recurrence. These three cases emphasise the importance of a comprehensive medical history and imaging in patients with small-bowel obstruction to determine the possibility of bezoars.

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.

Laparoscopic treatment for multiple huge diospyrobezoars in the stomach

We report a case of a patient with multiple diospyrobezoars, a phytobezoar attributed to persimmons (Diospyros kaki) consumption, in the stomach, who was treated with laparoscopic complete surgical excision. A 76-year-old man with gastric phytobezoars presented to our hospital. Abdominal contrast-enhanced computed tomography revealed three well-defined, oval, nonhomogeneous masses with a mottled appearance in the stomach. Esophagogastroduodenoscopy revealed three large brown solid phytobezoars and gastric ulcers at the gastric angle. The clinical diagnosis was diospyrobezoar, and, due to the huge masses, the patient eventually underwent laparoscopic treatment when the medical and endoscopic approaches were unsuccessful. After gastrotomy in the anterior wall of the stomach, the phytobezoar was mobile inside the stomach, which was opened beside the gastric incision. The three phytobezoars were removed through the wound protector using sponge-holding forceps; the hole in the gastrotomy was closed in the mucosal and seromuscular layers with an intracorporeal suture technique. The weight and size of the phytobezoars were 140 g and 115 × 55 × 50 mm, 70 g and 55 × 45 × 35 mm, and 60 g and 50 × 40 × 35 mm, respectively. The patient was discharged on the 8th postoperative day without any complications. Laparoscopic surgery to extract bezoar is the treatment of choice for this rare entity, because it is a safe and effective approach.

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.

Robotic-assisted extraction of giant gastric trichobezoar: a case report

Trichobezoar is a rare condition, almost exclusively seen in young females with certain psychiatric disorders. Trichobezoars are usually confined within the stomach and the complications include ulceration, perforation, intussusception and obstruction for which surgery is usually required. Most of the reported cases of giant gastric trichobezoar extraction underwent an exploratory laparotomy with only a few reported cases that underwent a successful laparoscopic approach. This case report details the surgical management of the first case of a giant obstructing gastric trichobezoar extraction using robotic-assisted surgery.
