Transanal endoscopic microsurgery: A forgotten minimally invasive operation

Transanal Endoscopic Microsurgery Excision

“…The advantage of the technique is the avoidance of a major abdominal procedure, and not surprisingly, the main emphasis in the literature to date has been on oncologic outcomes and improvements in technique rather than functional outcome. [2][3][4][5] TEM involves dilation of the anal sphincter with a large-diameter (4 cm) operating sigmoidoscope to accommodate optics, suction, and insufflation, as well as ports for dissecting instruments. In some cases, the procedure may be prolonged.…”

Transanal excision of benign rectal polyps: Indications, technique, and outcomes

“…Most available data concerns patients operated with a rigid transanal endoscopy system (for instance TEM, Karl Storz GmbH & Co, Tuttlingen, Germany. Using this setup, a rigid one port system equipped with a rectoscope, stereoscopic optical system, insufflation device and airtight working inserts for instruments is inserted transanally [7,15]. A documentation endoscope can be attached for video projection.…”

Local full-thickness excision for sessile adenoma and cT1-2 rectal cancer: long-term oncological outcome

“…In 1983, the transanal endoscopic microsurgery (TEM) system was introduced as a technique to ease local rectal surgery [ 3 ]. The first results published by TEM pioneers have shown it to be technically superior to the conventional peranal approach, with significantly lowers recurrence rates and an ability to access the entire rectum [ 4 , 5 ]. The TEM technique gained widespread support during the latter years of the last century and renewed the interest in local rectal surgery among surgeons.…”
