A systematic review of hernia surgery in SIL (single-incision laparoscopy) technique

Hernia repair in single-incision laparoscopic surgery (SIL) technique has become increasingly common at specialized centers. Still, safety issues and potential benefits of SIL hernia repair have to be elucidated. This review summarizes available literature and provides an overview of current developments. A literature search was performed in PubMed, the Cochrane Database, and Google for peer-reviewed publications on SIL hernia repair. Main outcome parameters were defined, and it was attempted to define clinical recommendations. SIL technique can be applied for inguinal, ventral, and hiatal hernia repair. Operation times and early results seem to be comparable with standard multiport laparoscopy. Distinct advantages of SIL hernia surgery have yet to be demonstrated, as the level of evidence in this field is low. Randomized controlled trials investigating the incidence of incisional hernias at the trocar site and safety in large cohorts are missing.
