This study sought to describe a procedure involving laparoscopically assisted total gastrectomy (LATG) with sentinel node biopsy (SNB) and to evaluate the results of the first three patients. LATG for early gastric cancer was performed with sentinel node (SN) identification using a combined patent blue-violet dye and 99mtechnetium-labeled tin colloid technique. Laparoscopically resected SNs were processed for frozen section examination by routine hematoxylin and eosin (H&E) and immunohistochemical cytokeratin (IHC-CK) stains. LATG consists of a four surgical port technique, removal of the specimen through a small 5-cm laparotomy, and stapled Roux-en-Y esophagojejunostomy. Five patients were candidates for LATG with SNB between March 2001 and June 2003; two bad open surgery because of a tumor extending the serosal surface and peritoneal dissemination, whereas in the remaining three, SNs were successfully identified and evaluated with no evidence of sentinel node (micro) metastases intraoperatively. Based on the results of SNB, three patients underwent LATG with adequate lymphadenectomy. Mean operative time and blood loss were 375 min and 219 mL, respectively. No dissected lymph nodes had evidence of metastasis by H&E and IHC-CK on permanent sections. LATG with SNB followed by adequate lymphadenectomy is technically feasible, and with its acceptable operative time and blood loss, presents an excellent therapeutic option for early gastric cancer; while SNB and subsequent frozen section analysis by H&E and IHC-CK staining is a rapid and reliable diagnostic method for intraoperative detection of SN (micro) metastasis. This combination treatment is a promising alternative to laparoscopic gastrectomy with conventional lymphadenectomy.
