Laparoscopic vs open inguinal hernia repair - A randomized, controlled trial

Background: The role of laparoscopic inguinal hernia repair is controversial. The aim of this study was to find out whether it is justified to switch from the predominantly modified Bassini repair which the authors had been using to laparoscopic repair. Methods: Randomized controlled trial in 120 eligible patients admitted for elective hernia repair in a university hospital. Results: Sixty patients underwent laparoscopic transabdominal preperitoneal mesh repair; the other 60 patients had an open repair, mostly with the modified Bassini technique. Operative time for laparoscopic repair was significantly longer, mean (s.d.) 95 (28) min vs 67 (27) min (p < 0.001). The mean analogue pain score during the first 24 h after surgery was 36.2 (20.2) in the laparoscopic group and 49.3 (24.9) in the open group (p = 0.006). The requirement for narcotic injections and postoperative disability in walking 10 m and getting out of bed were also significantly less following laparoscopic repair. The postoperative hospital stay was not significantly different, mean 2.6 (1.2) days for laparoscopic repair and 3.0 (1.5) days for open repair (p = 0.1). Patients were able to perform light activities without pain or discomfort sooner after laparoscopic repair, median interquartile range 8 (5-14) days vs 14 (8-19) days (p = 0.013). Patients also resumed heavy activities sooner, but not significantly, after laparoscopic repair, median 28 (17-60) days vs 35 (20-56) days (p = 0.25), The return to work was not significantly different, median 14 (8-25) days after laparoscopic repair and 15 (11-21) days after open repair (p = 0.14). After a mean follow-up of 32 months one patient developed a recurrent hernia 3 months after a laparoscopic repair. Laparoscopic repair was more costly than open repair by approximately $400. Conclusions. Laparoscopic inguinal hernia repair was associated with less early postoperative pain and disability and earlier return to full activities than open repair, but there were no benefits regarding postoperative hospital stay and return to work; laparoscopic repair was also more costly.
