Abstract:
Objective
To investigate the safety and efficacy of intravenous indocyanine green navigation surgery in radical gastrectomy.
Methods
Nine patients receiving intravenous indocyanine green guided radical gastrectomy were enrolled.All patients underwent standard D2 lymph node dissection and lymph node sorting.Indocyanine green was injected at 0.5h, 4h and 12h before surgery, respectively.Perioperative indexes, imaging effects of tumor and lymph nodes, the ratio of tumor and lymph nodes to surrounding tissue,the number of lymph nodes sorted at each station and the total number were analyzed.Measurement data with normal distribution were represent as (Mean±SD).
Results
The mean operation time of the included patients was (206.7±33.1) min, the intraoperative blood loss was (161.1±48.6) ml, and the postoperative hospital stay was (10.1±1.8) d.None of the 9 patients had serious complications.The imaging of tumor and lymph nodes could be achieved at all three time points.The highest ratio of tumor to normal gastric mucosal tissue was (2.5±0.4) at 0.5h,and the highest ratio of lymph node to surrounding tissue was (1.9±0.6) at 12h.The total number of lymph nodes was (74.0±29.2).
Conclusions
Intravenous indocyanine green navigation radical gastrectomy is effective.
