An evidence-based approach for laparoscopic inguinal hernia repair: lessons learned from over 1,000 repairs.

In this educational article, we aim to provide a literature review on laparoscopic anatomy of the inguinal region. We share the lessons learnt from the 1,194 laparoscopic hernia operations we have performed in 16 years of experience, trying to provide an anatomical and physiological basis for surgeons. The current study reports a personal experience with a transabdominal preperitoneal (TAPP) hernioplasty procedure. A literature review using the keywords "hernia," "laparoscopic approach," and "hernia repair" was performed using the electronic biomedical database PubMed, Medline Extra, Embase, Biosis, Science Citation Index, Ovid and text books. Between January 1994 and December 2010, a total of 1,194 patients, males and females (average age, 56.7 years), underwent laparoscopic TAPP inguinal hernia repair. Following reduction of the hernia sac and creation of the preperitoneal flap, a polypropylene mesh (10 × 16) and four spiral tacks were placed. TAPP is easy to learn and perform. Through this approach, a much better view from the inguinal anatomy is achieved, and the procedure also offers a brief learning curve. Our patients reported minimal postoperative pain and returned to work after 5-10 days, which is in accordance with the general anesthesia series. During the follow-up period, 10% of seromas, 3% of scrotal hematomas, 1% of hemorrhages, and 3% of recurrent hernias were observed. It should be emphasized that we have not observed abscess formation or acute infection related to the presence of mesh.
