RESUMO
Objective To investigate the effects of the laparoscopic surgery and open surgery on the postoperative intestinal function recovery time in elderly patients with colorectal cancer(CRC).Methods 66 elderly patients with CRC and treated in the 2nd People's Hospital of Kunming from January 2021to July 2022 were chosen and divided into the control group(n = 33)and the study group(n = 33)according to different operation ways.And the postoperative bowel function recovery time,radical,complications and surgical index were compared between the two groups.Results The recovery time of intestinal function in the study group was significantly shorter than that in the control group(P<0.05),but there was no significant difference in radical indicators between the two groups(P>0.05).The incidence of complications in the study group was lower than that in the control group,and the difference was statistically significant(P<0.05).The operation time of the study group was longer than that of the control group and there was the statistically significant difference(P<0.05),while the bleeding was less than that of the control group and there was the statistically significant difference(P<0.05).Conclusion Compared with the open surgery,laparoscopic surgery can more effectively shorten the recovery time of postoperative intestinal function,reduce the incidence of complications and intraoperative blood loss in elderly patients with CRC.Although there is no significant difference between two kinds of operation mode in terms of radical,it should be considered when it is applied in the specific operation time and other factors.
RESUMO
Objective:To evaluate the influence of different CO2 pneumoperitoneum pressure on intestinal mucosal injury and intestinal function recovery in patients undergoing laparoscopic radical gastrectomy.Methods:A total of 120 patients undergoing laparoscopic radical gastrectomy were randomly divided into group A,B and C.Each group included 40 patients.CO2 pneumoperitoneum pressure ingroup A,B and C were 8～10 mmHg,11～13 mmHg and 14～16 mmHg,respectively.The degree of intestinal mucosa damage,plasma D-lactate(2,24 and 48 hours after the treat-ment),intestinal function recovery and complication ration were compared between the three groups.Results:Damage degree of intestinal mucosa after operation in A,B and C groups were 0～1,1～2 and 2～3 respectively.There was significant change in intestinal mucosa injury after operation in both B and C groups.The level of D-lactic acid in group C (2,24 and 48 hours after the treat-ment) were significantly higher those in group A and group B (P＜0.05).The bowel sounds appeared time,exhaust time and intake time in group C were significantly longer than group A and group B (P＜0.05).The incidence of complications were not significantly difference during the three groups.Conclusion:The high pressure of CO2 pneumoperitoneum will cause intestinal mucosa damaged,and not conducive to the patients' intestinal rehabilitation.We suggest that the CO2 pneumoperitoneum pressure should be as low as possible under clear visualization during operation.
