Intraluminal Resection of Gastric Tumors Using Intragastric Trocar Technique

Introduction We are presenting our experiences with combined laparoscopic and endoscopic approaches applied to the minimally invasive intragastric resection of the gastric tumors. Patients and Method We performed the above-mentioned combined intragastric resection in 7 patients. The intragastric resection is only used with posterior gastric wall tumors and tumors located near the cardia and the pylorus. For this approach, only 1 trocar is placed into the stomach to intragastrically introduce the endostapler. We used 2 trocars (5 mm) into the abdominal cavity for laparoscopy. Results We have performed the combined laparoscopic and endoscopic intragastric resection in 7 patients. The tumor size was 38±7 mm (28-48 mm). The histology revealed 6 gastrointestinal stromal tumors and 1 leiomyoma. All 7 patients began eating and drinking on the second postoperative day. None of the patients showed any intraoperative or postoperative complications. The median postoperative hospital stay was 6.1 days (4-7 d). Conclusions The combined intraluminal resection using 1 intragastric trocar of potential benign posterior gastric wall tumors, of tumors near the cardia and the pylorus is a safe surgical procedure with low invasivity and morbidity.
