Based on a review of the literature, this paper provides an update on surgical treatment of middle and low rectal cancer and discusses issues of debate surrounding that treatment. The main goal of the surgical treatment of rectal cancer is radical resection of the tumor and surrounding lymphatic tissue. Local excision of early rectal cancer can be another treatment option, in which the patient ...

thors called for a more selective use of TME. The authors argue that oncologic outcome is not compromised with this approach based on similar cancer-specific survival patterns between TME and PME in this study. This conclusion was confirmed by metaanalysis. Mirnezami et al. [6] examined the long-term oncological impact of anastomotic leakage after rectal cancer surgery using meta-analysis metho...

A 52-year-old Japanese man presented for evaluation and treatment of rectal cancer. Screening computed tomography revealed pancreatic arteriovenous malformations (P-AVMs) and abnormally expanded inferior mesenteric vein (IMV) that resulted from P-AVMs. One-stage surgery for rectal cancer was dangerous so we first performed distal pancreatectomy to cure P-AVM and thus normalize the abnormally ex...

With enhanced surgical techniques and neoadjuvant therapy in rectal cancer, survivorship issues are at the forefront of clinical practice and research. More and more patients are living with altered bowel habits following rectal cancer surgery. Sound assessment of anorectal function after rectal cancer surgery is the foundation for the continuing effort to explore the adverse effects of such su...

BACKGROUND Prostate cancer involving the rectal wall is rare and may lead to diagnostic pitfalls. CASE PRESENTATION Out of 9504 patients with rectal tumors between January 2003 and January 2015, 9 patients (elderly with a mean age of 74 years) with prostate cancer involving the rectal wall were clinically misdiagnosed with rectal cancer. The lesions were located in the rectum, and included 3 ...

Objective This study was performed to investigate the incidence of and potential risk factors for rectal pain after laparoscopic rectal cancer surgery. Methods We retrospectively analyzed data from 300 patients who underwent laparoscopic rectal cancer surgery. We assessed the presence of rectal pain and categorized patients into Group N (no rectal pain) or Group P (rectal pain). Results In tota...

We investigated the association of oral contraceptive (OC) use and reproductive factors with colorectal cancer risk in a large population-based case-control study. Cases were women ages 20 to 74 years, living in Wisconsin, with a new diagnosis of colon (n = 1,122) or rectal (n = 366) cancer. Control participants were randomly selected from population lists of similarly aged female Wisconsin res...

PURPOSE Currently, circumferential resection margins (CRM) are used as a clinical endpoint in studies on the prognosis of rectal cancer. Although the concept of a circumferential resection margin in extraperitoneal rectal cancer differs from that in intraperitoneal rectal cancer due to differences in anatomical and biologic behaviors, previous reports have provided information on CRM involvemen...

Preoperative imaging for staging of rectal cancer has become an important aspect of current approach to rectal cancer management, because it helps to select suitable patients for neoadjuvant chemoradiotherapy and determine the appropriate surgical technique. Imaging modalities such as endoscopic ultrasonography, computed tomography, and magnetic resonance imaging (MRI) play an important role in...
