Objective
In Japan, laparoscopic inguinal herniorrhaphy(LH) is not popular. We performed a retrospective study to evaluate the results of LH in our hospital.
Patients
Between August 1992 and February 2008, 286 patients with 315 hernias were operated on at our department.
Standard method of LH in our hospitalTransabdominal preperitoneal approach
Veress needle is inserted via umbilicus
Trocar size umbilicus:5mm right:5mm left:3mm
Umbilicus : 30°laparoscopeRight : scissors, forceps, needle holder introduction of mesh and tackerLeft : forceps
Mesh : polyester or polypropylene soft ( average size:14×9cm )

The advantage-11. Improved cosmesis
LH Postoperative 7 months
LH Postoperative 7 months
Open repair Postoperative 2 years

The advantage-22. Less postoperative pain Earlier return to normal activity Less chronic postoperative pain
《 meta-analysis of randomized control trial 》
・ less postoperative pain, more rapid return to normal activity The EU Hernia Trialists Collaboration: Br J Surg 87:860-867, 2000
・ less persisting pain The EU Hernia Trialists Collaboration: Ann Surg 23:322-332, 2002
・ lower incidence of chronic pain Schmedt CG, et al: Surg Endosc 19:188-199, 2005
The advantage-33. Initial visualization of a recurrent hernia defect ( the avoidance of scar tissue dissection around the area of the previous repair )

With relation to open tension-free repair
・ higher cost
・ less postoperative pain
・ earlier return to work

The advantage-77. Diagnosis of unsuspected contralateral hernia ( in TAPP )
※In our practice, it is 3.8% ( 11/286 ) .
・ The reported laparoscopically detected incidence of occult contralateral hernias is between 11.2% and 50%. Koehler RH.: Surg Endosc 16:512-520, 2002
The disadvantage-11. Increased operative cost ( general anesthesia, equipment )
But
・ The total cost for working patients are lower with the laparoscopic technique, when the cost of lost work days is factored into overall expense. Heikkinen T. et al: Surg Endosc 12:1199-1203, 1998
・ From a societal perspective, laparoscopic approach can be a cost-effective treatment option for inguinal hernia repair. Stylopoulos N. et al: Surg Endosc 17:180-189, 2003
The disadvantage-2
2. Specific training and long learning curve
Learning curve is
・ 30–50 cases DeTurris SV. et al: J Am Coll Surg 194:65-73,
2002
・ 40 procedures Lim M. et al: Surg Endosc 20:1453-1459, 2006
※ Some authors have quantified the LH learning curve at 30–250 hernia repairs.
The disadvantage-3
3. Major complications and recurrences during the learning curve
※We experienced two severe complications. ( one bladder injury and one trocar site hernia )
〔 Reported serious complications 〕 ・ visceral injury (bladder, intestine, etc. ) ・ vascular injury ( iliac artery, etc. ) ・ trocar site hernia ・ bowel obstruction ・ testicular ischemia ・ nerve injury ( genitofemoral nerve, etc. )
