Abstract: Objective To investigate the effect of Lightweight Stereoscopic 3D Patch on complications,pain and quality of life followed up for one year in elderly patients with inguinal hernia treated with laparoscopic TAPP. Methods The clinical data of 203 elderly patients with inguinal hernia admitted and diagnosed in our hospital from September 2018 to August 2020 were retrospectively analyzed.All patients were treated with laparoscopic TAPP,and were included in the control group(105 cases) and the treatment group(98 cases) according to the different hernia patches in the data.The control group was given ordinary patch,and the treatment group was given Lightweight Stereoscopic 3D Patch.Postoperative pain was assessed by visual analogue scale(VAS),and quality of life before and after surgery was assessed by the Comprehensive Quality of Life Questionnaire-74(GQOLI-74).The surgery-related conditions,complications,postoperative pain,and quality of life before and after surgery were compared in two groups. Results The operation time[(57.34±4.69)min],postoperative ambulation time[(27.53±5.46)h] and hospital stay[(7.85±1.12)d] in the control group were longer than those in the treatment group[(50.65±4.31)min、(20.39±5.26)h、(5.76±0.73)d](P<0.05).The incidence of postoperative complications in the treatment group(3.06%) was significantly lower than that in the control group(11.43%)(P<0.05).The VAS scores of the control group at 1 day(3.89±0.84),4 days(3.47±0.74),7 days(2.82±0.64) ，1 month(1.74±0.46)after operation were higher than those in the treatment group[(3.01±0.57),(2.63±0.55),(2.09±0.52),(1.12±0.41)](P<0.05).One year after the operation,the scores of mental health(74.13±5.67),material life status(70.49±6.44),physical health(71.56±6.43) and social function(75.86±4.21) in the treatment group were significantly higher than those in the control group [(62.39±4.39),(61.53±4.35),(60.93±5.76),(62.82±3.24)](P<0.05). Conclusion Lightweight Stereoscopic 3D Patch combined with laparoscopic TAPP in the treatment of elderly patients with inguinal hernia has fewer postoperative complications,and at the same time can effectively relieve postoperative pain and improve the quality of life.
