Methods: The data of 78 patients who underwent laparoscopic radical resection of right-sided colon cancer between January 2018 and August 2019 were retrospectively analysed. The surgical method was selected by the patients. The patients were divided into two groups according to the surgeons’ positioning habits and trocar placements. The group with the lead surgeon standing between the patient’s legs had 35 patients, and the group with the lead surgeon standing at the left side of the patient had 43 patients. The operation time, intraoperative blood loss, postoperative anal gas evacuation time, postoperative urinary catheter indwelling time, postoperative hospital stay, C-reactive protein (CRP) level on the first day after surgery, and postoperative pathological data and complications were compared between the two groups. Results: All patients underwent the laparoscopic radical resection of right-sided colon cancer, none converting to laparotomy. No significant difference (P > 0.05) in intraoperative blood loss (57.6 ± 21.3 ml vs 60.2 ± 35.3 ml), postoperative anal gas evacuation time (3.5 ± 1.1 d vs 3.8 ± 1.3 d), postoperative urinary catheter indwelling time (2.6 ± 1.3 d vs 2.4 ± 1.2 d), postoperative hospital stay (7.1 ± 1.8 d vs 7.5 ± 2.1 d), or CRP level on the first day after surgery (54.7 ± 9.6 mg/L vs 53.9 ± 8.2 mg/L) was detected between the two groups. The operation time was shorter in the group with the lead surgeon standing between the patient’s legs (185.2 ± 25.6 min vs 196.2 ±19.7 min) (P < 0.05). The two groups did not differ significantly in the tumour length (4.2 ± 1.3 cm vs 3.9 ± 1.5 cm), number of dissected lymph nodes (27.5 ± 11.6 vs 25.1 ± 15.4), pathological type, or postoperative pathological tumour-node-metastasis stage (P > 0.05). No patients died or had anastomotic fistula during their postoperative hospital stay, and the incidence of postoperative complications did not differ between the two groups (22.9% (8/35) vs 23.3% (10/42);P > 0.05). Conclusion: Under the principle of radical resection, the surgeon should adopt the most suitable standing position and trocar placement according to the specific situation. If the surgeon stands between the patient’s legs, this might shorten the operation time and promote a smoother surgery.展开更多

Control group of patients received BIS-monitored manually adjusted targeted-controlled infusion concentration of propofol, and observation group of patients received BIS-monitored closed-loop targeted-controlled infusion of propofol. The differences in hemodynamic index levels as well as serum contents of inflammatory factors and stress hormones were compared between the two groups of patients before anesthesia (T0), 30 min after surgery started (T1) and 30 min before surgery ended (T2).Results:At T0, the differences in hemodynamic index levels as well as serum contents of inflammatory factors and stress hormones were not statistically significant between the two groups. At T1 and T2, hemodynamic indexes MAP and HR levels of observation group were lower than those of control group at the corresponding time points;serum inflammatory factors sICAM-1, IL-1β, IL-8 and TNF-α contents were lower than those of control group at the corresponding time points;serum stress hormones Cor, T4 and glucagon contents were lower than those of control group at the corresponding time points.Conclusion: BIS-monitored closed-loop targeted-controlled infusion of propofol can effectively stabilize the intraoperative hemodynamics and inhibit the systemic inflammatory stress response in patients with laparoscopic radical operation for gastric cancer.展开更多

Method:140 patients with colon cancer admitted to a hospital from January 2016 to November 2017 were divided into control group and observation group according to the operation method, 70 cases in each group. The control group was treated with open radical resection of colon cancer, while the observation group was treated with laparoscopic radical resection of colon cancer. The changes of immune function, stress response, visceral protein and gastrointestinal hormone were compared between the two groups before and after treatment.Results:There was no significant difference in immune function, stress response, visceral protein and gastrointestinal hormone between the two groups before operation (P>0.05). The ratio of Th1 cells was decreased, while the ratio of Th2, Th17 and Treg cells was increased in the two groups (P<0.05). The proportion of Th1 cells in the observation group was higher than that in the control group,while the ratio of Th2, Th17 and Treg cells in the observation group was lower than that of the control group (P<0.05). The levels of Cor, E and NE were increased in the two groups (P<0.05). And the levels of Cor, E and NE in the observation group were lower than those in the control group (P<0.05). The levels of PA, TRF and RBP were decreased in the two groups (P<0.05). And PA, TRF and RBP levels were higher in the observation group than in the control group (P<0.05). The GAS, MTL and GIP levels were lower in the two groups (P<0.05). And the GAS, MTL and GIP levels in the observation group were higher than those in the control group (P<0.05).Conclusion: Laparoscopic radical mastectomy has little effect on the immune function of patients. It can alleviate the surgical stress response to a certain extent, which is beneficial to the recovery of gastrointestinal function and can be extended to clinical application.展开更多
