title: Simultaneous bilateral laparoscopic inguinal hernia repair: an analysis of 1336 consecutive cases at a single center.
abstract: BACKGROUND
  We compare the use of unilateral and simultaneous bilateral laparoscopic hernioplasty [transabdominal preperitoneal patch (TAPP)]
  
  
  METHODS
  We employed a prospective consecutive single-center trial lasting from April 1993 to December 2000.
  
  
  RESULTS
  In our study, 5524 consecutive patients underwent 6860 laparoscopic hernia repairs. The median age in group A (unilateral repair, n = 4188) was 58 years (16-94 years), and that in group B (simultaneous bilateral repair, n = 1336) was 60 years (19-97 years) in (simultaneous bilateral repair, n = 1336). Morbidity in group A was 3.2% (135/4188) with a 0.6% reoperation rate (24/4188); in group B morbidity was 5.0% (67/1336) with a 1.4% reoperation rate. (19/1336). Morbidity and reoperation rates showed no statistically significant difference between the two groups in relation to number of repairs in group B. After a median 24-month clinical follow-up period (1-84 months) (follow-up rate 93.1%) 38 recurrences were observed in group A (0.9%) and 17 in group B (0.6%; 17/2672) (p = 0.2668). Median time off work was 14 days after unilateral (2-63 days) and 17 days after bilateral repair (3-100 days) (p = 0.1359). Pain levels (numerical analogue scale) and incidence of persistent inguinal and scrotal pain are not higher after bilateral repair.
  
  
  CONCLUSIONS
  Compared to unilateral repair, bilateral simultaneous laparoscopic hernia repair (TAPP) is safe, comfortable for patients, and cost-effective, without increased morbidity or recurrence risk. Bilateral inguinal hernia is an ideal indication for endoscopic transabdominal repair.
