Objective To explore method of jejunum nutrition tube implantation in total laparoscopic radical gastrectomy for distal gastric cancer (GC). Methods The clinical data of 30 patients with distal GC underwent the total laparoscopic radical gastrectomy from October 2017 to March 2018 in the Departmeng of Tumor Surgery, Lanzhou University Second Hospital were retrospectively analyzed, the total laparoscopic radical distal gastrectomy were performed in all the patients and the jejunum nutrition tube were implanted during the operation. Results Thirty patients with distal GC were successfully treated with the total laparoscopic radical gastrectomy and the jejunum nutrition tubes were implanted into under the total laparoscopy through the intraoperative guidance by the gastric tube, firstly fastening the nutrition tube to the gastric tube in vitro, and then separating them in vivo, finally the nutrition tube was smoothly implanted into the jejunum under the direct vision. The implantation time was 10 to 15 min with an average of 13.5 min. The jejunal nutrition tube retention time was 5 to 7 d with an average of 6 d. There were no complications such as the bleeding, anastomotic leakage, anastomotic obstruction, stenosis, intestinal leakage, intestinal obstruction, and other complications after the operation in the 30 patients. Conclusions Method of jejunum nutrition tube implantation in total laparoscopic radical gastrectomy for distal GC is easy to be performed. Intraoperative and postoperative complications are few. It provides a favorable guarantee for improving postoperative nutritional status of patient with distal GC.
ObjectiveTo investigate the research progress of assisted techniques for lymph node dissection in gastric cancer. Method The literatures on the applications of assisted techniques of lymph node dissection in the gastric cancer radical gastrectomy in recent years were reviewed. ResultsAt present, the assisted techniques used for lymph node dissection in the radical gastrectomy mainly included the lymphatic tracing technology and laparoscopic and robotic surgeries. The lymphatic tracing technology mainly included the use of dye tracers, indocyanine green, gamma probe, intraoperative radiation technology, etc. Among which gamma probe and intraoperative radiation technology were expensive and not suitable for clinical application, and intraoperative radiation technology had a radiation risk, so it was rarely used currently. At present, the dye tracers and indocyanine green were mainly used in the clinical lymph node tracing, both of which could improve the detection rate and increase the number of lymph node dissection, and improve the prognosis of patients. The laparoscopic radical gastrectomy was not inferior to traditional radical gastrectomy in terms of lymph node dissection, and had been more widely used in the clinical practice due to its advantages of visualization, minimally invasive, quickly postoperative recovery, and good short-term efficacy. Compared with the conventional laparoscopic system, the robotic surgical system was more precise, dexterous, stable, and had a better feedback feeling, which was more conducive to the lymph node dissection of special location. ConclusionUse of lymphatic tracers, laparoscopy and robotics could increase lymph node detection rate and improve prognosis of patients.
