ObjectiveTo investigate the feasibility of hand-assisted laparoscopic surgery in radical gastrectomy for gastric cancer. MethodsThe data of two cases undergoing hand-assisted laparoscopic radical gastrectomy for gastric cancer, including operative time, operation related complications, intraoperative bleeding volumes, number of harvested lymph nodes, postoperative complications, time to restoration of bowel function, and length of postoperative hospital stay, etc, were retrospectively analyzed. ResultsTwo patients had undergone the successful hand-assisted laparoscopic radical total gastrectomy and distal gastrectomy without operation related complications. The operative time was 310 min and 220 min, respectively. While, the intraoperative bleeding volume was 120 ml and 80 ml with the number of harvested lymph node being 38 and 52, respectively. There were no postoperative bleeding, intestinal fistula, and anastomotic leakage， etc. The patients were discharged with smooth and fully recovery. ConclusionThe application of hand-assisted laparoscopic surgery in radical gastrectomy for gastric cancer is feasible and safe. However, the effectiveness needs further exploring.
ObjectiveTo explore the differences and similarities of the featurs of lymph node metatasis of abdominal esophageal carcinoma and cardiac cancer. MethodsPreoperative CT images of abdominal esophageal carcinomas and cardiac cancers were reviewed and analysed on lymph node size and preponderant distribution. ResultsShort diameter ≥10 mm of lymph node at CT was adopted as metastasis criterion. The detection rates of abdominal esophageal carcinomas and cardiac cancers were 73.5%（144/196） and 83.7% （170/203）, respectively. Thoracic lymph node metastasis rate of abdominal esophageal carcinomas was 11.1% （4/36） in 7 area, 27.8% （10/36） in 8 area, 8.3% （3/36） in 9 area, while celiac lymph node metastasis rate was 36.1% (13/36 ） in No.7 group, 19.4% （7/36） in No.1 group, and 11.1% （4/36） in No.2 group primarily. Lymph node metastasis rate of cardiac cancers was 17.9% （5/28） in No.1 group, 28.6% （8/28） in No.2 group, 39.3% （11/28 ） in No.3 group, and 25.0% （7/28） in No.4 group for the first stop lymph nodes, and 35.7% （10/28 ） in No.7 group for the second stop primarily. ConclusionAs metastasis criterion, short diameter ≥10 mm of lymph node at CT is feasible, but there exist certain falsepositive rate. Thoracic lymph node metastasis of abdominal esophageal carcinomas is mainly in the 7, 8, and 9 area, while celiac metastasis is mainly in No.7, No.1, and No.2 groups. Lymph node metastasis of cardiac cancers is in No.1, No.2, No.3, No.4, and No.7 group primarily.
