Objective: To present the technique for and early results of laparoscopic intragastric resection (LIGR).
Background: Treatment of confirmed or suspected submucosal gastric malignancies relies on clear margin resection, for which minimally invasive surgery is widely accepted. However, resection in some localization remains challenging.
Methods: We present the steps of LIGR for gastric submucosal tumors (GSMTs). We report the results of LIGR in consecutive patients operated at 2 institutions, including intraoperative, pathologic, 30-day major morbidity and mortality characteristics.
Results: After laparoscopic access to the abdominal cavity, cuffed gastric ports are placed to approximate the anterior gastric wall to the abdominal wall. A pneumogastrum is created. The tumor is resected in the submucosal plane and the deficit closed with intragastric suturing. Specimen extraction is performed perorally or through a gastrotomy site. In 8 proximal intraluminal GSMTs with median size of 3.1 cm (range: 1.8-6.0 cm), median operative time was 167.5 minutes (range: 120-300 mins). There was no major morbidity and no mortality. All resections were R0.
Conclusions: We illustrate the technique of a novel, feasible, and safe minimally invasive approach to GSMTs. LIGR is an alternative to resect challenging GSMTs by limiting surgical invasiveness and preserving gastrointestinal function.
