[Single incision laparoscopy : Current status].

BACKGROUND

Since the introduction of single incision laparoscopy (SIL), there has been disagreement among professional societies regarding a general recommendation for the use of this minimally invasive method.

OBJECTIVES

Determination of evidence-based advantages of SIL compared to multiport laparoscopy (MPL).

MATERIALS AND METHODS

Description of recent technical developments and evaluation of prospective randomized clinical trials and valid meta-analyses with regard to organ-specific procedures. In addition, an expert opinion is provided based on 4209 SIL interventions.

RESULTS

SIL is nowadays applied in all fields of general and visceral surgery. Due to the initial enthusiasm, methodologically weak studies were often published in the literature. Any beneficial effect of SIL on reduced perioperative morbidity is not clearly confirmed, yet. A better cosmetic outcome is either obvious (in SIL liver resections) or nearly unverifiable (in SIL cholecystectomies).

CONCLUSION

SIL has proven feasible and safe after getting through the learning curve. Scientific evidence is currently insufficient to justify SIL without reservation in particular without the individual technical experience of the surgeon.
