background: colorectal carcinoma is the third most common cause of death in iran. this study was performed in order to determine the appropriate distal clearance margin (dcm) for resection of rectal cancer in patients who undergo neoadjuvant chemoradiotherapy for sphincter preserving procedure. materials and methods: this was a cross-sectional study conducted in shahid faghihi hospital of shira...

Anastomotic leak after low anterior resection (LAR) in patients with rectal cancer who have received neoadjuvant chemoradiation can be challenging to treat and can lead to the creation of a permanent stoma. We report the case of a post-operative anastomotic leak after a Baker-type anastomosis during a low anterior resection was successfully managed with transanal endoscopic microsurgical (TEM) ...

This study documents the complete larval development of the Monkey River Prawn Macrobrachium lar using a new greenwater rearing technique. Approximately 6,000 larvae were reared for 110 days at an initial stocking density of 1 ind./6 L. Salinity at hatch was 10 ± 2 ppt and progressively increased to 30 ± 2 ppt until decapodids had metamorphosed. Temperature was maintained at 28 ± 0.5°C, pH at 7...

PURPOSE Impaired functional outcome is common after a low anterior resection (LAR). Pelvic floor rehabilitation (PFR) might improve functional outcome after a LAR. The aim of this systematic review is to evaluate the effectiveness of PFR in improving functional outcome. METHODS PubMed, Embase, and the Cochrane Library were searched using the terms fecal incontinence, colorectal neoplasm/surge...

PURPOSE Robotic surgery is expected to have advantages over laparoscopic surgery; however, there are limited data regarding the feasibility of robotic surgery for rectal cancer after preoperative chemoradiotherapy (CRT). Therefore, we evaluated the short-term outcomes of robotic surgery for rectal cancer. MATERIALS AND METHODS Thirty-three patients with cT3N0-2 rectal cancer after preoperativ...

The curative treatment of rectal cancer is based on radical TME surgery. It is well admitted that abdomino-pelvic-resection (APR) is a severe body mutilation due to permanent stoma. More and more it is recognized that even low anterior resection (LAR) is not providing a very good quality of life because the LAR syndrome is often present and distressful [1]. For that reason a new way of clinical...

PURPOSE For several decades, the low anterior resection (LAR) with total mesorectal excision (TME) has been the gold standard for treating patients with rectal cancer. Up to 90% of patients undergoing sphincter-preserving surgery will have changes in bowel habits, so-called 'anterior resection syndrome.' This study examined patients' continence after a LAR for the treatment of rectal cancer. ...

BACKGROUND AND OBJECTIVES Splenic flexure mobilization (SFM) is performed to ensure a tension free anastomosis with an adequate resection margin in laparoscopic anterior resection (AR) or low anterior resection (LAR). This retrospective study was performed to determine the amount of colonic redundancy that can be expected by SFM. METHODS Retrospective review of medical record for a total of 2...

Low rectal tumors have increasingly been treated by sphincter-saving operations (SSO), but some patients with a low anterior resection (LAR) or a coloanal anastomosis (CAA), with or without (chemo)radiotherapy, may suffer from a defecation disorder called “anterior resection syndrome” (ARS). Frequent bowel action, urgency, symptoms of fecal incontinence, that characterize anterior resection syn...
