Abstract:Abstract: Objective?To investigate the impact of laparoscopic inguinal hernia repair on the surgical effect and T lymphocyte percentage.?Methods?From January 2017 to January 2019, 280 patients with inguinal hernia were selected as subjects and randomly divided into control group (n?=?140) and observation group (n?=?140). The control group used open tension-free hernia repair, and the observation group used laparoscopic tension-free hernia repair. The patient’s effect was evaluated 7 days after surgery. The surgical indicators, visual pain simulation score (VAS), percentage of T lymphocytes, and postoperative complications.?Results?There was no significant difference in the operation time between the two groups (P?>?0.05). The amount of bleeding, postoperative autonomic activity time and VAS score in the observation group were less (lower) than those in the control group (P?0.05). More than the control group (P?0.05); The percentage of CD3+, CD4+, CD4+/CD8+ 7 days after surgery in the observation group was higher than that in control group (P?0.05); The percentage of CD8+ 7 days after surgery in the observation group was lower than that in control group (P?0.05); The incidence of incision pain, urinary retention, scrotal edema, and incision infection in the observation group was not statistically significant compared with the control group (P?>?0.05).?Conclusion?Laparoscopic surgery is less invasive in patients with inguinal hernia, which can improve the percentage of T lymphocytes in patients and does not increase the incidence of postoperative complications. It is worth of popularizing and applying.
