TEM Surgery

author/s: Dr. Josep M Montané Sorigué

 

What does TEM mean?

TEM stands for transanal endoscopic microsurgery. TEM is a minimally invasive technique which consists in the excision of tumours that meet the following criteria:

    • Tumours involving only the rectal mucosa.
    • Tumours that extent at most up to half of the rectal lumen circumference.
    • Tumours that are at a maximum distance of 15 cm from the anal margin.


Professor Buess from the University of Tubinghen was the first to apply this technique which consisted in introducing a catheter through the anus resecting the lesion through this same catheter.

What are the differences between TEM and a colonoscopy?

A colonoscopy is a diagnostic and therapeutic tool used mainly to diagnose inflammatory or neoformative diseases of the colon by means of a biopsy. It can also be applied therapeutically for resection of lesions, mainly polypoid lesions. See animation (colonoscopy).

 

What preparation is required to undergo TEM?

The prep is that as for a colonoscopy.

 

What are the complications of TEM?

Non-significant hospital complications................................4%    
Surgical complications, bleeding, suture dehiscence............8%

 

How long will I be in the hospital?

Normally, if there are no complications, the hospital stay lasts no more than two to three days.

 

What post-operative caret must I follow after the operation?

The post-operative care is the same as for conventional surgery of the rectum.
