Abstract:
Objective To investigate the clinical efficacy of laparoscopic vagus nerve and pylorus-preserring gastrectomy (LVNPPG) for early gastric cancer.Methods The retrospective descriptive study was conducted.The clinical data of 5 patients who underwent LVNPPG for early gastric cancer at the Peking University Cancer Hospital between May 2016 and September 2016 were collected.Patients underwent laparoscope-assisted or total laparoscopic vagus nerve (hepatic branch and celiac branch) and pylorus-preserving gastrectomy.Observation indicators:(1) surgical situations;(2) postoperative situations;(3) postoperative pathological examination;(4) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect survival of patients and tumor metastasis and recurrence up to December 2016.Measurement data with normal distribution was represented as average (range).Results (1) Surgical situations:of 5 patients undergoing successful LVNPPG,digestive tract reconstruction using auxiliary incision was conducted in 3 patients and total laparoscopic surgery in 2 patients.Three patients received appliance side-to-side anastomosis and 2 received manual end-to-end anastomosis.Hepatic branch and celiac branch of vagus nerve in 5 patients were preserved.Average operation time and volume of intraoperative blood loss were 220 minutes (range,180-305 minutes) and 108 mL (range,30-216 mL).(2) Postoperative situations:average time to initial bowel exsufflation,average times for fluid diet intake and for semifluid diet intake were 3 days (range,2-4 days),3 days (range,1-5 days)and 10 days (range,5-25 days),respectively.One patient complicated with delayed gastric emptying was improved by conservative treatment.Duration of hospital stay of 5 patients was 13 days (range,7-32 days).(3)Postoperative pathological examination:number of lymph node dissected,average lengths of proximal margin and distal margin were 22 (range,15-35),3.5 cm (range,2.2-5.0 cm) and 3.7 cm (range,2.0-5.5 cm),respectively.Pathological T stage:pT0 stage was detected in 1 patient,pT1a stage in 1 patient,pT1b stage in 2 patients and pT2 stage in 1 patient.Pathological N stage:pN0 stage was detected in 3 patients and pN2 in 2 patients.Pathological TNM stage:0 stage was detected in 1 patient,Ⅰ a stage in 2 patients,Ⅱ a stage in 1 patient and Ⅱb stage in 1 patient.Two patients had stage migration,including from cT1N0 to pT2N2 and from cT0N0 to pTlbN2.(4) Follow-up situations:5 patients were followed up for 2.8-7.0 months,with a median time of 5.6 months.During follow-up,there were no death and occurrence of tumor metastasis and recurrence.Conclusion LVNPPG is safe and feasible for early gastric cancer.
