In September 2004 the NICE institute revised its guidelines on the management of primary inguinal hernias to include laparoscopic repair of unilateral hernias. While published trials have confirmed the equal efficacy of the two approaches, it is not clear what impact a switch to laparoscopic repairs would have on resources and patient throughput in a Day Surgery Unit.
Method: All elective hernia repairs performed in a one-year period were considered. Data were obtained from operation notes, discharge summaries and out-patient records. Operating times are routinely documented in theatre.
Results: Of the 351 operations studied, 150 were performed laparoscopically predominantly by an extraperitoneal (TEP)approach. Six required conversion to an open procedure. There was no significant difference in operating times, total theatre time or recovery room times between the two groups (51 min, 75 min and 34 min for the laparoscopic group and 53 min, 74 min and 31 min for the open repair group). Among the laparoscopic repair group there were 48 bilateral hernias and 20 recurrent hernias while 190 of the 201 open repairs were for primary unilateral hernias. Rates of overnight stay and immediate complications were similar between the groups though haematoma was more common following open repair (7 vs 2).
Conclusions: There is no difference in theatre times, immediate complication rates or rates of overnight stay between open and laparoscopic repair of inguinal hernia. Routine laparoscopic repair of primary unilateral inguinal hernia is a viable alternative within the Day Surgery Unit.
