ABSTRACT
Objective:To investigate the application value of the anatomically oriented "six steps with six windows" approach in laparoscopic radical total gastrectomy.Methods:The retros-pective cohort study was conducted. The clinicopathological data of 121 patients who underwent laparoscopic radical total gastrectomy in Henan Provincial People′s Hospital from January 2019 to February 2022 were collected. There were 53 males and 68 females, aged (68±12)years. Of the 121 patients, 72 patients using the traditional approach in the surgery were divided into the control group, and 49 patients using the "six steps with six windows" approach in the surgery were divided into the experiment group. Observation indicators: (1) surgical situations; (2) postoperative situations. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Count data were described as absolute numbers or percen-tages, and comparison between groups was conducted using the chi-square test. Results:(1) Surgical situations. All 121 patients underwent laparoscopic radical total gastrectomy successfully, without laparotomy conversion. The operation time, volume of intraoperative blood loss, number of lymph nodes dissected were (250±50)minutes, (150±34)mL, 41±6 in the control group, versus (180±16)minutes, (55±13)mL, 51±5 in the experiment group, showing significant differences in the above indicators between the two groups ( t=11.04, 21.47, 9.42, P<0.05). (2) Postoperative situations. The times of postoperative analgesic injection, time to postoperative ?rst ?atus, duration of postoperative hospital stay, postoperative pathological staging (stage Ⅰ, stage Ⅱ, stage Ⅲ), incidence of postoperative complication were 3.4±1.6, (4.0±1.4)days, (13.1±2.0)days, 9, 32, 31, 15.3%(11/72) in the control group, versus 3.5±1.7, (4.1±1.5)days, (13.1±1.7)days, 6, 25, 18, 16.3%(8/49), showing no significant difference in the above indicators between the two groups ( t=0.35, 0.18, 0.03, Z=0.55, χ2=0.02, P>0.05). There was no perioperative death in both groups of patients. Conclusion:Appli-cation of the anatomically oriented "six steps with six windows" approach in laparoscopic radical total gastrectomy is safe and feasible.
