To analyze the clinical effect of the transverse hernia sac on laparoscopic inguinal hernia repair in the treatment of Gilbert type Ⅲ inguinal hernia.

From January 2016 to December 2019, the clinical data of 285 patients with unilateral Gilbert III inguinal hernia treated by laparoscopic inguinal hernia repair at the Ninth People's Hospital Affiliated to the Medical College of Shanghai Jiaotong University were analyzed retrospectively. According to the treatment method of hernia sac, they were divided into transverse hernia sac group of 150 cases and complete dissection hernia sac group of 135 cases. Operation mode, operation time, intraoperative bleeding, postoperative pain score, postoperative hospital stay, postoperative seroma, postoperative chronic pain, postoperative hematoma, incision infection, and recurrence of the two groups were analyzed and compared.

The incidence of postoperative seroma in the transverse hernia sac group was significantly lower than that in the complete dissection hernia sac group (P<0.05); There was no significant difference between the two groups in operation time, intraoperative bleeding, postoperative pain score, postoperative hospital stay, postoperative chronic pain, postoperative hematoma, or incision infection (P>0.05). The two groups were followed up for one year without recurrence.

When laparoscopic inguinal hernia repair is used to treat Gilbert III inguinal hernia, intraoperative transection of the hernia sac can effectively reduce the incidence of postoperative seroma.
