Transanal minimally invasive surgery: an initial experience.
Summary of "Transanal minimally invasive surgery: an initial experience."
Transanal minimally invasive surgery (TAMIS) is a novel approach used for the resection of rectal lesions. The purpose of this study was to review our initial experience with TAMIS.
Between March 2012 and May 2012, we collected clinical data on patients who underwent the TAMIS procedure. This included patient demographics, tumour characteristics, operative technique, histological results and post-operative outcomes.
Three patients successfully underwent TAMIS resection of rectal lesions. All tumours were tubulovillous adenomas with high-grade dysplasia, with one also having a small focus of adenocarcinoma. Clear margins were achieved in all cases. One case was complicated by a post-operative bleed, requiring a return to theatre.
TAMIS is a feasible and cost-effective alternative to transanal endoscopic microsurgery for resection of rectal lesions. It may have a shorter learning curve, especially for laparoscopic surgeons already proficient in single-port procedures.

Transanal minimally invasive surgery for total mesorectal excision (TAMIS-TME): results and experience with the first 20 patients undergoing curative-intent rectal cancer surgery at a single institution.
Transanal TME is a new approach to performing minimally invasive rectal resection. It is particularly well suited for patients with locally advanced distal rectal cancer and obesity, where the abdomin...
Laparoscopic total mesorectal excision can be difficult in a narrow pelvis. Transanal minimally invasive surgery allows the surgeon to mobilize the most distal part of the rectum by using a single por...
This study aimed to compare the short- and long-term results of minimally invasive surgery (MIS) and open surgery for primary early gastric cancer (EGC) at a single high-volume institution.
In the 1990s, the success of 'minimally invasive' laparoscopic operations in other surgical subspecialties sparked an interest in minimally-invasive approaches for cardiac surgery, specifically for mi...
The purpose of this study is to determine if there is a difference in terms of length of hospital stay and post-operative outcomes between patients whose total hip replacement surgery is p...
During surgery for obesity, minimally invasive endoscopy can be performed and can assist the surgeon in determining surgical incision sites.
The purpose of this study is to evaluate and compare the clinical, radiographic (x-ray) and cost effectiveness outcomes (cost relative to risks and benefits) of two different minimally inv...
The purpose of this study is to evaluate a multimodal analgesic protocol used in minimally invasive surgery for myomectomies (laparoscopic myomectomy (LM) and laparoscopically assisted my...

Medical and Biotech [MESH] Definitions
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
Lung infections with the invasive forms of ASPERGILLUS, usually after surgery, transplantation, prolonged NEUTROPENIA or treatment with high-doses of CORTICOSTEROIDS. Invasive pulmonary aspergillosis can progress to CHRONIC NECROTIZING PULMONARY ASPERGILLOSIS or hematogenous spread to other organs.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Minimally invasive procedures, diagnostic or therapeutic, performed within the BLOOD VESSELS. They may be perfomed via ANGIOSCOPY; INTERVENTIONAL MAGNETIC RESONANCE IMAGING; INTERVENTIONAL RADIOGRAPHY; or INTERVENTIONAL ULTRASONOGRAPHY.
