This study demonstrates that transanal NOTES with minilaparoscopic assistance in the hands of a specialized team is safe; meets the oncologic requirements for high-quality rectal cancer surgery; and may offer advantages over pure laparoscopic approaches for visualizing and dissecting out the distal mesorectum. Minilaparoscopic assistance allows one to compensate for the limitations of current NOTES instrumentation to ensure the safety and adequacy of oncologic resection in these difficult cases. Careful patient selection, a specialized team, and long-term outcome evaluation are critical before this procedure can be considered for routine clinical use.

In this preliminary report, transrectal minilaparoscopy-assisted low anterior resection was feasible and safe. Lateral/end-to-end anastomoses can be considered an interesting alternative to the double-stapling technique. However, it is necessary to further study and develop these procedures, along with careful patient selection, before transrectal low anterior resection may be considered for routine clinical use.

LSG is a feasible bariatric procedure carried out increasingly in the last few years with low postoperative complications. Regardless, the knowledge of the potential complications associated to LSG and their management is crucial for patient's safety.

Surgical treatment has been in constant evolution in the search for minimizing incisions regardless of the complexity of the operation. Natural Orifice Translumenal Endoscopic Surgery (NOTES) represents this progression of surgery to less invasive procedures. Transanal endoscopic microsurgery (TEM) is an ideal NOTES platform to access the peritoneal cavity endoscopically through the anus and specifically to allow colorectal resections be performed through smaller, or indeed without, abdominal incisions. Transanal rectosigmoidectomy with total mesorectal excision (TME) using TEM is a feasible and oncologically safe option. Such use of currently available combined hybrid laparoendoscopic systems provides a safe platform to define future clinical applications and advantages of NOTES. Furthermore, it stimulates the active development of technologies that will support and enable it.

Transumbilical single-port sleeve gastrectomy has proved to be safe, technically feasible, and reproducible, with results that are similar to those obtained with conventional laparoscopic surgery.

Transrectal MA-NOS total colectomy was feasible and safe in the reported case. Improvement in NOTES instrumentation and selective clinical applications are mandatory before clinical trials.
