The Ferguson Operating Anoscope (FOA) is a surgical instrument, which can facilitate transanal excision of appropriate rectal tumors within 15 cm of the anal verge. Previous work showed low recurrence (4.3%) for favorable T1 tumors (no lymphovascular invasion, well/moderate differentiation, negative margins). This follow-up study evaluates outcomes in rectal cancer excised with FOA at a tertiary care center. T1 rectal cancer patients were identified in a prospectively maintained database. Tumor pathology and patient characteristics were reviewed...

Liu He, Yi Xiao
Transanal total mesorectal excision (taTME) is a novel operative approach of the radical surgery for rectal cancer, and has been a hot topic in colorectal surgery for years. TaTME aims to solve some problems from previous TME, such as exposure of peripheral mid-lower rectal space, judge of distal cutting margin, and to carry out completely minimal invasive operation. According to the degree of completion of different surgical approach, taTME can be divided into laparoscopic assisted taTME (hybrid taTME) and fully through the anal approach to complete the taTME (pure taTME)...

Transanal total mesorectum excision (taTME) is a novel approach to treat rectal cancer by colorectal surgeons. How to standardize taTME is important for colorectal surgeons, especially at their initial attempt. They can start this approach cautiously only after they master skilled laparoscopic technique and pelvic anatomy, get the knowledge of taTME clearly, and are approved by healthcare department. The female patients with age <70 years old, distance of 5 to 7 cm from tumor inferior margin to anal verge, tumor size <3 cm, cTNM stage <T3aN0 are suitable for taTME...

Transanal endoscopic microsurgery (TEM) is currently the only one-port system in endoscopic surgery, which a direct endoluminal approach can lead to the target organ through a natural opening of human body. TEM has been applied in colorectal surgery for over 3 decades. Compared with radical surgery, TEM has the advantages, such as quicker recovery, shorter hospital stay and fewer complications. One perfect TEM surgical system, which mainly consists of three parts, namely peculiar rectoscope for surgery, special surgical instruments and imaging system, is the foundation of standardized development of TEM...

Colorectal carcinoma is the second leading cause of cancer-related deaths in the United States, with rectal cancer accounting for approximately one-third of newly diagnosed cases, thus representing a major socioeconomic health burden. Although minimally invasive procedures (ie, transanal excision) may be appropriate for a subset of patients with small, superficially invasive tumors, a more comprehensive trimodality approach with neoadjuvant chemoradiotherapy, total mesorectal excision, and systemic chemotherapy is recommended for medically operable patients with nonmetastatic, locally advanced rectal cancer (LARC)...

BACKGROUND: Perianal Paget's disease (pPD) is uncommon, with only about 180 cases documented in the literature. Anorectal carcinoma with pagetoid spread is even rarer. CASE PRESENTATION: An 81-year-old woman underwent rectal cancer extirpation with a transanal approach 17 years prior. She has since undergone two reoperations for local rectal cancer recurrence. Then, warts frequently appeared on the vulva on several occasions. Warts appeared on the vulva 1 year ago, which were diagnosed as pPD by biopsy...

OBJECTIVE: This study aims to compare surgical outcome of transanal ileal pouch-anal anastomosis (ta-IPAA) with transabdominal minimal invasive approach in ulcerative colitis (UC), using the comprehensive complication index (CCI). BACKGROUND: Recent evolutions in rectal cancer surgery led to transanal dissection of the rectum resulting in a better exposure of the distal rectum and presumed better outcome. The same approach was introduced for patients with UC, resulting in decreased invasiveness...

Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

BACKGROUND: Several studies have shown the transanal total mesorectal excision (TATME) is emerging as a safe and effective technique for proctectomy. The majority of these studies to date, however, is based on procedures done in centers with teams of two surgeons working simultaneously. Few were performed by single-surgeon teams with sizeable case load. The objective of our study was to identify the feasibility and safety of a single-surgeon TATME. METHODS: Chart review of prospectively collected data on 27 patients who underwent TATME at our institution from June 2015 to September 2016 were included in this study...

Transanal total mesorectal excision (TaTME) is a new surgical technique in the treatment of selected patients with rectal cancer. This manuscript and the accompanying video report with commentary, which is available online, outlines various equipment requirements and step by step aspects of the surgical technique. With respect to the implementation of TaTME particular attention should be paid to the topography and surgical education.

Over the last decade, with the acceptance of the need for improvements in the outcome of patients affected with rectal cancer, there has been a significant increase in the literature regarding treatment options available to patients affected by this disease. That treatment related decisions should be made at a high volume multidisciplinary tumor board, after pre-operative rectal magnetic resonance imaging and the importance of total mesorectal excision (TME) are accepted standard of care. More controversial is the emerging role for watchful waiting rather than radical surgery in complete pathologic responders, which may be appropriate in 20% of patients...
