ABSTRACT Because of the concerns over the operative platform, accidental organ injury, and viscerotomy closure, natural orifice transluminal endoscopic surgery (NOTES) currently remains an experimental technique. Transanal NOTES for colorectal surgery overcomes all of these issues; however, all of the reports to date have used hybrid laparoscopic techniques. We demonstrate herein the first case, to our knowledge, of pure transanal NOTES colorectal surgery.
Case report.
University hospital.
The patient was a 56-year-old woman with a midrectal neoplasia.
Pure transanal NOTES total mesorectal excision with a coloanal anastomosis and without a diverting stoma. Using a transanal endoscopic operation device as a surgical platform, we created a viscerotomy distal to an endoluminal purse-string suture. We performed a total mesorectal excision using a “bottom-up” approach. The sigmoid colon was mobilized by a posterior, retroperitoneal approach and the colon was divided intraperitoneally. A hand-sewn, side-to-end, coloanal anastomosis was performed. Because the viscerotomy was incorporated into the anastomosis, the concerns of both accidental organ damage and viscerotomy closure were abrogated.
The procedure was completed entirely by a transanal fashion. We successfully mobilized the rectum, mesorectum, and sigmoid colon. The specimen length was more than 20 cm. The patient required minimal analgesia and her pain was nonabdominal.
To our knowledge, the first pure transanal NOTES total mesorectal excision with retroperitoneal sigmoid mobilization and coloanal, side-to-end anastomosis was successfully performed using what we called a peri-rectal oncologic gateway for retroperitoneal endoscopic single site surgery (PROGRESSS). This monumental case could pave the way for a new era in pure transanal NOTES for colorectal surgery.

    ABSTRACT: Single-incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have rapidly gained pace worldwide, potentially replacing conventional laparoscopic surgery (CLS) as the preferred colorectal surgery technique. Currently available data mainly consist of retrospective series analyzed in four meta-analyses. Despite conflicting results and lack of an objective comparison, SILS appears to offer cosmetic advantages over CLS. However, due to conflicting results and marked heterogeneity, present data fail to show significant differences in terms of operative time, postoperative morbidity profiles, port-site complications rates, oncological appropriateness, duration of hospitalization or cost when comparing SILS with conventional laparoscopy for colorectal procedures. The application of "pure" NOTES in humans remains limited to case reports because of unresolved issues concerning the ideal access site, distant organ reach, spatial orientation and viscera closure. Alternatively, minilaparoscopy-assisted natural orifice surgery techniques are being developed. The transanal "down-to-up" total mesorectum excision has been derived for transanal endoscopic microsurgery (TEM) and represents the most encouraging NOTES-derived technique. Preliminary experiences demonstrate good oncological and functional short-term outcomes. Large-scale randomized controlled trials are now mandatory to confirm the long-term SILS results and validate transanal TEM for the application of NOTES in humans.

    ABSTRACT: The aim of this retrospective study was to compare conventional laparoscopic living-donor nephrectomy with transvaginal natural orifice transluminal endoscopic surgery-assisted living-donor nephrectomy in terms of feasibility and reproducibility. A total of 115 consecutive female patients who underwent laparoscopic living-donor nephrectomy (n = 70) or transvaginal natural orifice transluminal endoscopic surgery-assisted living-donor nephrectomy (n = 45) were included and compared in terms of operative characteristics, as well as donor and recipient outcomes. No significant difference was observed between the laparoscopic living-donor nephrectomy and transvaginal natural orifice transluminal endoscopic surgery-assisted living-donor nephrectomy groups in terms of mean duration of warm and cold ischemia, operation time, length of hospital stay, arterial anastomoses, visual analog scale pain scores, serum creatinine levels, and receiver outcomes, whereas a significantly higher number of venous anastomoses was noted in the laparoscopic living-donor nephrectomy group than in the transvaginal natural orifice transluminal endoscopic surgery-assisted living-donor nephrectomy group (P = .029). Transvaginal natural orifice transluminal endoscopic surgery-assisted living-donor nephrectomy seems to be a feasible and reproducible alternative to conventional laparoscopic living-donor nephrectomy in female donors provided the viability of the vagina as an organ retrieval route.
