Pyloric botulinum toxin injection and single-port laparoscopic intragastric surgery for bulbus hamartoma

Gastrointestinal polyps are associated with risks such as bleeding, intussusception, obstruction and malignancy, necessitating removal. Technological advancements in endoscopic and laparoscopic surgery have introduced minimally invasive options like laparoscopic intragastric surgery (LIGS), especially beneficial for polyps that cannot be resected endoscopically. This report presents a 37-year-old male patient with Peutz–Jeghers Syndrome who exhibited symptoms of nausea, vomiting and weight loss. Endoscopy and computed tomography imaging revealed obstructive polyps in the bulbus and gastric cardia. The patient underwent single-port LIGS with preoperative botulinum toxin injection to facilitate pyloric opening. This combined approach allowed effective lesion resection without requiring extensive gastric resection. Pathology confirmed a hamartomatous polyp in the bulbus and high-grade dysplasia with negative margin in the gastric cardia. LIGS, particularly with botulinum toxin assistance, appears to be a safe and effective method for excising intraluminal lesions in complex anatomical areas, such as the duodenal bulbus and cardia.
