Abstract

Extraction site incisional hernia (IH) has been recognized as an important complication in minimally invasive procedures but has not been as well characterized following robotic-assisted laparoscopic prostatectomy (RALP). Approximately 29% of IH required surgical repair. A number of techniques have been utilized to reduce the rates of IH following minimally invasive procedures. First, off-midline extraction was investigated, this did not demonstrate a reduction in incisional hernia rates. Recently, supra-umbilical transverse incisions have been utilized to extract prostate specimen and this method decreased the extraction site IH rate compared to the vertical midline incision. In addition, the choice of fascial closure technique and choice of the suture may influence the incidence of extraction site IH. For example, studies showed that abdominal fascial closure using a nonabsorbable suture and a continuous running suture technique decreased IH rate from 32 to 17%. Finally, "the small bites technique" has been recommended to reduce hernia incidence after midline fascial closure following a randomized controlled trial (RCT) which demonstrated the superiority of the small-bite technique. In summary, a supra-umbilical transverse incision to extract the specimen was shown to decrease the rate of extraction site IH. In vertical midline incisional closure, the small bites technique with slowly- or non-absorbable suture, such as #0 or 2-0 PDS II with SH or CT-2 needle (26 mm arch length), reduces the IH rate. Urologists should consider this data to reduce the risk of IH following RALP.
