Comparison Of Short-term Outcomes Of Laparoscopic D2Distal Gastrectomy And D2+CME Distal Gastrectomy

Objectives:It is suggested that complete mesogastrium excision(CME) is imperative for radical gastrectomy of gastric cancer,which can also reduce local-regional recurrence and improve survival time of patients with gastric cancer.Here we try to compare D2versus D2+CME in clinical trials under the use of laparoscopy-assisted distal gastrectomy (LATG). Therefore, this study was designed to evaluate the short-term of D2+CME as well as the safety and feasibility of the technique, using a case-control study.Methods:A total of27D2and26D2+CME were retrospectively matched with respect to sex, age (±5years),and pathological tumor-node-metastasis stage for comparison of the clinical outcomes.Results:The total complication rate among27D2and26D2+CME was0%(0/26) and0%(0/26),respectively. there were no significances in the Time to first gas passing and time to the resumption of a soft diet,the postoperative hospital stay of LATG between the D2group and D2+CME group. However, the number of dissected lymphnodes was more in D2+CME group(26.2±11.8) than in D2patients (18.2±10.6,p<0.05). The estimated blood loss under laparoscopy was less in D2+CME group(7.5±5.0) than in D2patients(97.6±131.3,p<0.01).Conclusions:D2+CME for gastric cancer has the advantage over an D2in terms of better short-term outcomes. D2+CME is an acceptable alternative to D2for the treatment of gastric cancer.
