RESUMO
Objective To assess the feasibility and safety of modified laparoscopic totally extraperitoneal(TEP)hernia repair.Methods From January to August 2007,a total of 31 patients with hernia were treated with modified TEP hernia repair under general anesthesia in our hospital.During the operation,the anterior peritoneal space was separated,and then a domestic single balloon catheter was inserted into the extraperitoneal space to expand the latter.The mesh was not fixed during the operation.Results All the operations were successfully completed with a mean operation time of(69.8?21.8)minutes,mean blood loss of(7.6?4.2)ml,and mean postoperative hospital stay of(2.6?1.3)d.Five cases developed laceration of the peritoneum during the operation,and 2 had scrotal hydrocele after the operation.The patients were followed up for 1-7 months [mean,(4.2?2.4)months],no recurrence or chronic pain at operative area were found during this period.Conclusions Modified TEP is feasible for hernia repair.The method is a safe and tension-free technique with a low rate of postoperative chronic pain at the operation region.
