| [ Summary ] |
Recently, laparoscopy and endoscopy cooperative surgery (LECS), which was developed by Hiki et al, has been widely accepted as a safe and useful procedure of local resection for gastric tumor such as gastrointestinal stromal tumors (GIST) and early gastric cancer in various clinical situations. Inoue et al, also invented a combination of laparoscopic and endoscopic approaches to neoplasia with a nonexposure technique (CLEAN‒NET) for gastric neoplasms. It is regarded as a modified LECS procedures. The CLEAN‒NET allows performance of full‒thickness gastric wall resection without any leakage of gastric contents into the abdominal cavity. We have performed the CLEAN‒NET in 48 patients. None of the patients experienced a recurrence of malignancy to date. The CLEAN‒NET could enable minimally invasive surgery for gastric tumors without the risk of tumor dissemination. |
