Abstract：Objective：To observe the changes of pain and gastrointestinal peristalsis function in patients after surgery for gastric cancer before and after percutaneous point electrical stimulation. Methods：A total of 80 patients after surgery for gastric cancer were divided into the control group and the trial group by random number table method， with 40 cases in each group. The trial group was given perioperative conventional treatment and percutaneous point electrical stimulation， and the control group was given perioperative conventional treatment and percutaneous point stimulation，but the power was not turned on. The postoperative recovery time， pain by Numerical Rating Scale (NRS)， gastrointestinal peristalsis function indexes， including serum gastrin (GAS)， motilin (MOT)， somatostatin (SS)， Substance P (SP)， neurotensin (NT)， cholecystokinin (CCK) and vasoactive intestinal peptide (VIP)， T lymphocyte subsets， including plasma CD3+，CD4+ and CD4+/CD8+，gallbladder volume，gallbladder empty rate，and abdominal pressure were compared before and after surgery in the two groups. Results： The time of bowel sounds back to normal， anal farting time， defecation time and hospitalization time in the trial group were shorter than those in the control group (P＜0.05). After surgery，the NRS scores and the levels of serum VIP，SS and NT in the two groups were decreased when compared with those before surgery (P＜0.05)， and the levels of serum MOT，GAS，SP and CCK were increased when compared with those before surgery (P＜ 0.05)；the NRS score and the levels of serum VIP，SS and NT in the trial group were lower than those in the control group，and the levels of serum MOT，GAS and CCK in the trial groups were higher than those in the control group (P＜0.05)，and there was no significant difference in SP levels between two groups (P＞0.05). After surgery，the levels of CD3+，CD4+ and CD4+/CD8+ in the two groups were increased when compared with those before surgery (P＜0.05)， and the levels of CD8+ were decreased when compared with those before surgery (P＜0.05)；the levels of CD3+，CD4+ and CD4+/CD8+ in the trial group were higher than those in the control group (P＜0.05)， and the CD8+ level was lower than that in the control group (P＜0.05). Conclusion： Percutaneous point electrical stimulation can effectively reduce pain， improve immune function，gastrointestinal peristalsis function，and promote postoperative recovery in patients after surgery for gastric cancer.
