Background
There has been a trend toward minimally invasive treatment of early gastric cancer. We report the preliminary results of laparoscopy-assisted distal gastrectomy with laparoscopic sentinel lymph node biopsy after endoscopic mucosal resection.
Methods
Six patients underwent laparoscopy-assisted distal gastrectomy after endoscopic mucosal resection between February 2002 and October 2005 at Mie University Hospital. These patients first underwent laparoscopic sentinel lymph node biopsy and then laparoscopy-assisted distal gastrectomy with lymphadenectomy.
Results
No patient underwent conversion to open surgery during the operation. None of the patients had any postoperative complications. The mean length of postoperative hospital stay was 11.3 days. Sentinel lymph nodes were identified laparoscopically in five patients. There were 20 sentinel and 85 nonsentinel lymph nodes in the six patients. Postoperatively, tissue sections showed that none of the lymph nodes were metastasized. Immunohistochemistry with D2-40 antibody showed that there were normal lymphatics in the submucosal layer with mucosal defects at the endoscopic mucosal resection site. No patients had any tumor recurrence during followup.
Conclusions
Laparoscopy-assisted distal gastrectomy after endoscopic mucosal resection was a safe and curative procedure. Endoscopic mucosal resection before sentinel lymph node biopsy was acceptable for early gastric cancer.
