Abstract:Abstract: Objective To analyze the laparoscopic total mesenteric excision on gastrointestinal function for patients with low rectal cancer after operation. Method 165 cases diagnosed as low rectal cancer, patients lost were excluded from the study, which was divided into observation group (81 cases) and control group (81 cases). The control group were treated by the laparoscopic total mesenteric excision, the observation group were treated by traditional open total mesenteric excision. Operative time, incision lengths, hospital stay, intraoperative blood loss, postoperative fasting time, postoperative exhausting time, the number of eliminating lymph nodes and ache situation were collected and evaluated by specialist in our hospital. The situation of survival, recurrence and complications were followed and collected by specialist in our hospital. The levels of gastrin, IL-6 and IL-8 were measured by ELISA method. Result The difference was not statistically significant (P > 0.05) in the two groups of the number of eliminating lymph nodes, the difference was statistically significant (P < 0.05) in the two groups of operative time, incision lengths, hospital stay, intraoperative blood loss, postoperative fasting time, postoperative exhausting time and VAS scores. Although the operative time of the observation group was longer than that in control group, but operative time, incision lengths, hospital stay, intraoperative blood loss, postoperative fasting time, postoperative exhausting time and VAS scores were better than that in control group. No local recurrence, metastasis and death were observed in both groups. The difference was statistically significant (P < 0.05) in the two groups of complication rate after treatment, the complication rate in the observation group (13.58%) was lower than that in control group (30.86%). The difference was not statistically significant (P > 0.05) in the two groups of the levels of GAS, IL-6 and IL-8 at preoperative, the difference was statistically significant (P < 0.05) in the two groups of the levels of GAS, IL-6 and IL-8 immediately after the procedure, 1 and 3 days after surgery. The levels of GAS in observation was higher than that in controls. The levels of IL-6 and IL-8 in observation was lower than that in controls. Conclusions Laparoscopic total mesenteric excision is effective with low rectal cancer, and can make the gastrointestinal function recover faster than the usual, might play a certain role in suppressing inflammatory factor compared with traditional operation.
