Abstract

Background

Obesity patients sometimes have gastric submucosal tumors (SMTs). Surgical excision is recommended in cases of SMTs with suspected malignancy or other reasons making follow-up difficult. Laparoscopic intragastric surgery (LIGS) has recently achieved good results in the treatment of gastric SMTs, especially near the esophagogastric junction (EGJ). This procedure has enabled either preservation of the stomach or minimization of the extent of partial resection.

Methods

The patient is a 43-year-old female with BMI of 48.2 kg/m2 who is a candidate for LRYGB. A small SMT was found just below the EGJ. A follow-up with an endoscopy would be needed but difficult because the pouch was too small to observe the lesion. We decided to resect the tumor with LIGS and perform LRYGB simultaneously.

Results

We put the trocars as is our usual LRYGB practice. Observing with laparoscopy and endoscopy, three trocars were inserted into the stomach. After marking the margin of the tumor and injecting normal saline to the submucosal layer, resection of the tumor was performed. Suturing of the defects of the mucosa and the holes of the trocars on the stomach was performed. Then, we performed LRYGB as usual. The patient was discharged uneventfully. The pathological findings showed that the tumor was resected completely. Weight loss has succeeded as her BMI is 32.7 at 1 year after the surgery.

Conclusions

We performed LIGS and LRYGB simultaneously and safely for a morbidly obese patient with a gastric SMT, and our case is the first case of LIGS during a bariatric procedure.
