Transanal minimally invasive surgery for rectal neuroendocrine tumors

Surgical Endoscopy, 2020
There is no literature that mainly searched for rectal neuroendocrine tumor (rNET) using transanal minimal invasive surgery (TAMIS). We report our clinical experiences of TAMIS for rectal neuroendocrine tumors to evaluate the feasibility and safety.Between December 2010 and March 2020, the 25 consecutive patients with rectal neoplasma underwent the ...

eTAMIS: endoscopic visualization for transanal minimally invasive surgery

Surgical Endoscopy, 2012
Transanal endoscopic microsurgical (TEM) resection is associated with improved outcomes compared to transanal excision of rectal lesions. However, TEM equipment requires additional operative setup time, and tumor location dictates patient positioning. In 2010, Drs.

Robotic Transanal Minimally Invasive Surgery for Rectal Lesions

Surgical Innovation, 2020
Background. Transanal minimally invasive surgery (TAMIS) was developed as a less aggressive alternative treatment for rectal lesions. The purpose of this study was to report the results of robotic TAMIS for such patients. Methods. Patients eligible for TAMIS were operated on using the da Vinci robotic surgical system and GelPOINT Path Transanal Access ...

Transanal Minimally Invasive Surgery (TAMIS)

2014
Despite development of the transanal endoscopic microsurgery (TEM) system for 30 years, it is being used only by a handful of surgeons. High initial cost, complex instrumentation, steep learning curve, and the necessity for specialized training remain significant obstacles for wider adoption.

Transanal Minimally Invasive Surgery

Diseases of the Colon & Rectum, 2014
Currently, the preferred method for local excision of rectal polyps is transanal endoscopic microsurgery, avoiding rectal resection. Transanal minimally invasive surgery is a relatively new technique using a disposable port in combination with conventional laparoscopic instruments.

[Minimally invasive transanal surgery].

Nihon Geka Gakkai zasshi, 2000
A new anal retractor connected to an Octopus retractor holder and automatic suture clamp were used for local excision of rectal tumors to obtain easy access to proximal tumors with an adequate surgical field and to avoid complications. Shortening techniques and invagination techniques were adopted to pull down proximal tumors.

Robotic transanal minimally invasive surgery in a cadaveric model

Techniques in Coloproctology, 2011
The technique of TransAnal Minimally Invasive Surgery (TAMIS) was pioneered in 2009 as a hybrid approach to endoluminal resections of appropriately selected rectal lesions. There are, however, limitations to performing this type of resection. Robotic TAMIS is a novel, experimental technique and in this study was performed in a cadaveric model at a ...

Transanal minimally invasive surgery: a giant leap forward

Surgical Endoscopy, 2010
Our novel approach is a hybrid between transanal endoscopic microsurgery (TEM) and single-port laparoscopy that we have termed TransAnal Minimally Invasive Surgery (TAMIS). We report the clinical application of this technique and present preliminary data that show TAMIS to be an effective tool for resection of both malignant and benign lesions of the ...

Minimally Invasive Anorectal Surgery: From Parks Local Excision to Transanal Endoscopic Microsurgery to Transanal Minimally Invasive Surgery

Seminars in Colon and Rectal Surgery, 2013
Total mesorectal excision remains the preferred oncological treatment of tumors of the rectum, providing excellent cure rates and minimal local recurrence. Surgical advances have led to more sphincter-sparing procedures using coloanal anastomosis. However, abdominoperineal resection with permanent colostomy remains the most common procedure performed ...
