Enhanced recovery after surgery in laparoscopic distal gastrectomy: Protocol for a prospective single-arm clinical trial

BACKGROUND: The enhanced recovery after surgery (ERAS) programme is feasible and effective in reducing the length of hospital stay, overall complication rates and medical costs when applied to cases involving colonic and rectal resections. However, a recent prospective, randomised, open, parallel-controlled trial (Chinese Laparoscopic Gastrointestinal Surgery Study-01 trial), initiated by our team, indicated that under conventional peri-operative management, the reduction of the post-operative hospital stay of laparoscopic distal gastrectomy (LDG) is quite limited compared with open gastrectomy. Thus, if we could provide valuable clinical evidence for demonstrating the efficacy of the ERAS programme for gastric cancer patients undergoing LDG, it would significantly enhance the peri-operative management of gastrectomy and benefit the patients. METHODS: In this prospective single-arm trial, patients who are 18–75 years of age with gastric adenocarcinoma diagnosed with cT1-4aN0-3M0 and expected to undergo curative resection through LDG, are considered eligible for this study. All participants underwent LDG with peri-operative management under the ERAS programme. The primary outcome measures included the post-operative hospital stays and rehabilitative rate of the post-operative day 4. The secondary outcome measures are morbidity and mortality (time frame: 30 days), post-operative recovery index (time frame: 30 days), post-operative pain intensity (time frame: 3 days) and the medical costs from surgery to discharge. CONCLUSION: With reasonable and scientific designing, the trial may be a great help to further discuss the benefit of ERAS programme and thus improving the peri-operative management of patients with gastrectomy.
