Overview of Natural Orifices Specimen Extraction in Colorectal Surgery
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 3
Abstract
For the last three decades, different colorectal related to minimally invasive surgery techniques were developed. Those techniques reduced postoperative pain; wound complications also enhanced early reinitiating of bowel function and also decreased hospital stay duration. But incision formation for colorectal specimen retraction through abdominal wall ‘mini-laparotomy' negatively impacts those advantages of minimally invasive surgery. Natural orifice specimen extraction (NOSE), which is the extraction of the specimen via normal anatomical openings connected to the external environment such as Anus and Vagina. The establishment of this technique is to eliminate the abdominal wall incision needed for the specimen retraction, which improves surgical trauma induced problems and brings positive outcomes. The beneficial outcomes observed in laparoscopic-assisted NOSE in colorectal cancer resections include postoperative pain reduction and less demand for analgesics, faster return of intestinal function and decrease of hospital stay time. Besides the demonstration of the goodness of this technique in colorectal surgery, some shortage also had reported. Since there are no standardized and generalized criteria of patient selections, who could optimally benefit from NOSE procedures still needs further and deeper defining. In this review, we are focusing on the two most practised NOSE methods; transanal and transvaginal NOSEs in terms of their benefits and hazards.
