Ligation of intersphincteric fistula tract (LIFT) is a relatively new technique in the treatment of complex anorectal fistulas. As it spares the anal sphincter, rates of post-operative incontinence may be lower when compared to conventional treatment. To date, there have not been enough reports of long-term fistula recurrence rates. We performed a long-term follow-up study of 75 patients who underwent LIFT following seton drainage and partial fistulotomy.

The medial approach in laparoscopic splenic flexure mobilization is based on the entrance to the lesser sac just above the ventral edge of the pancreas (VEOP). The artery of Moskowitz runs through the base of the mesocolon, just above the VEOP. The aim of this study was to assess the incidence of the artery of Moskowitz, its route and its distance from the VEOP.

Ileostomy reversal is associated with surgical site infection (SSI) rates as high as 37%. Recent literature suggests that employing a purse-string approximation (PSA) of the reversal wound reduces this rate of SSI. Thus we wished to perform a randomised controlled trial to compare SSI rates in purse-string versus linear closure (PLC) wounds following ileostomy reversal.

Recently published data support the use of a web-based risk calculator ( ) for the prediction of anastomotic leak after colectomy. The aim of this study was to externally validate this calculator on a larger dataset.

Transanal total mesorectal excision (taTME) is an altogether different approach to rectal cancer surgery, and the effects of carbon dioxide (CO2) on this dissection remain poorly described.

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. Future directions in surgical imaging are also discussed, including the use of organic dyes, quantum dots, and carbon nanotubes; collectively, technology that could someday provide surgeons with an ability to identify anatomic structures prone to injury.

Anastomotic leak can be a devastating complication, and early prediction is difficult. The aim of this study is to prospectively validate a simple anastomotic leak risk calculator and compare its predictive value with the estimate of the primary operating surgeon.

Approximately one in five persons living in the USA is maintained on oral anticoagulation. It has typically been recommended that anticoagulation be withheld prior to hemorrhoidal procedures. Transanal hemorrhoidal dearterialization (THD) is a minimally invasive treatment for symptomatic hemorrhoids, and outcomes with patients on anticoagulation who have undergone this procedure have not been previously reported. Here, we report our preliminary results of patients who underwent THD while on anticoagulation.

Transanal total mesorectal excision (TaTME) is a novel approach pioneered to tackle the challenges posed by difficult pelvic dissections in rectal cancer and the restrictions in angulation of currently available laparoscopic staplers. To date, four techniques can be employed in order to create the colorectal/coloanal anastomosis following TaTME. We present a technical note describing these techniques and discuss the risks and benefits of each.

Transanal local excision (TLE) has become the treatment of choice for benign and early-stage selected malignant tumors. However, closure of the rectal wall defect remains a controversial point and the available literature still remains unclear. Our aim was to determine through a systematic review of the literature and a meta-analysis of relevant studies whether or not the wall defect following TLE of rectal tumors should be closed.
