Pingping Xu, Jianmin Xu
Robotic surgical system has been widely applied in sphincter-preserving surgery for low rectal cancer with the advantages of clear 3D images and stably flexile manipulation. Its application principle includes radical resection of tumor and complete preservation of function. The main operation procedures of robotic surgical system in sphincter-preserving surgery for low rectal cancer are as follows: (1) Anterior resection of low rectal cancer: It is safe and feasible and has obvious advantages in observation of pelvic nerves, dissociation of presacral and sacral side, and high rate of sphincter-preserving, while the improvement of postoperative recovery and long-term survival needs to be verified by further large sample researches...

BACKGROUND: The challenge of performing a good total mesorectal excision (TME) dissection, particularly in the distal 1/3 of the rectum, has spurred interest in new techniques. Robotic surgery is advocated by some, and more recently, a "new" approach, the transanal total mesorectal excision, has been popularized to address this problem. While great interest in this technique exists, little long-term outcome data are available. We have been utilizing a transanal abdominal transanal approach to TME in order to facilitate the distal dissection, and here, we provide our long-term outcomes using this approach in the management of rectal cancer...

Laparoscopic surgery is proven equal technique to open rectal surgery. Despite advantages, some problems in case of low rectal surgery are existing: visualization of the pelvis, securing safe distal resection margin, preparing single stapled rectal stump with safe conjunction to the colorectal anastomosis. Approximately 500 procedures have been performed worldwide until today by applying Transanal Total Mesorectal Excision (TaTME) technique, which evolved from a combination of laparoscopy and transanal approach...

W Kneist
Since the introduction of transanal endoscopic microsurgery (TEM) in the 1980 s, the minimally invasive transanal approach has been a treatment option for selected patients with colorectal diseases. Recently, transanal minimally invasive surgery (TAMIS) was introduced as an alternative technique. TAMIS is a hybrid between TEM and single-port laparoscopy and was followed by introduction of transanal total mesorectal excision (TaTME). Although the TaTME experience remains preliminary, it appears to be an attractive minimally invasive procedure for carefully selected patients with resectable rectal cancer...

The risk of urethral injury during transanal total mesorectal excision (taTME) is delineated, and potential risk factors for iatrogenic transection are reviewed. A variety of applied and theoretical techniques can be used by surgeons to diminish the risk of injury in males undergoing this operation. Many of the approaches utilize non-optic media and wavelengths beyond the visible light spectrum which can enhance the surgeon's frame of reference. The aim of the present study was to assess the techniques and theoretical approaches to urethral localization during taTME...

REVIEW
K Krogh, G Chiarioni, W Whitehead
Chronic constipation (CC) is an extremely common condition with an estimated prevalence of up to 24%. Most patients with CC should be treated in primary care. Changes in lifestyle, including increased intake of dietary fibre, fluid, and exercise, should be attempted in most patients. Osmotic or stimulant laxatives are indicated if there are insufficient effects of lifestyle changes. Prokinetics and secretagogues should be restricted to those not responding to basic treatment. Anorectal physiology tests and assessment of colorectal transit time are indicated if medical treatment fails or if symptoms indicate severely obstructed defecation...

INTRODUCTION: With any abdominal surgery in a difficult abdomen, the procedure is filled with potential hazards. In addition to a prolonged operative time, there is a risk of enterotomy or damage to blood vessels and ureters. An irradiated pelvis increases this risk and may cause additional morbidity such as delayed healing. An impacted foreign body can also be a challenging problem to deal with alone but when combined with a difficult abdomen can make the problem impossible. PRESENTATION OF CASE: A 67 year-old male presented with a small bowel obstruction secondary to a foreign body impacted in the distal...

BACKGROUND: Urethral injury is a complication feared by surgeons performing transanal TME (TaTME) or abdominoperineal excision (APE) procedures. Injury during TaTME occurs when the prostate is inadvertently mobilised or as a direct injury similar to the direct injury during the perineal dissection of APE procedures. We performed a proof of principle study to assess the feasibility of using indocyanine green (ICG) to fluoresce the urethra in human cadavers. METHODS: Indocyanine green at varying doses was mixed with Instillagel and infiltrated into the urethra of male human cadavers...

Total mesorectal excision (TME) is standard treatment of mid- and low rectal cancer and has evolved with minimally invasive surgery. Laparoscopic TME has proven to be technically challenging, and recent randomized controlled studies fail to prove it oncologically superior to open TME. Robotic-assisted TME may overcome the technical difficulties and shows comparable oncological results, yet it is associated with significant additional costs. Transanal TME is a promising method which seems to overcome the technical and financial issues of the other techniques, without compromising the short-term oncological results...

INTRODUCTION: Laparoscopic surgery has long been used for colon and rectal resection, and the laparoscopic-assisted approach has prevailed in surgical practice. While this technique includes the fashioning of an intra-corporeal anastomosis, it still requires an abdominal incision for specimen extraction. Elimination of the abdominal incision and its potential complications has been the motivation for the development of natural orifice specimen extraction (NOSE) techniques. Many of these techniques make use of an open rectal stump, which poses as a potential for intra-abdominal contamination...
