Ampullary gangliocytic paraganglioma with lymph node metastasis: A case report with literature review.

Rationale: Gangliocytic paraganglioma (GP) is a rare tumor that mostly develops in the duodenum and is composed of the following 3 cell types: epithelioid endocrine, spindle-like, and ganglion-like cells. It manifests as symptoms such as abdominal pain, gastrointestinal bleeding, and weight loss; however, occasionally, it is incidentally detected on endoscopic or radiologic examinations. Although GP is usually benign, it can metastasize to the lymph nodes, and distant metastases have been reported in some cases.

Transanal minimally invasive surgery using laparoscopic instruments of the rectum: A review.

Transanal minimally invasive surgery (TAMIS) was first described in 2010 as an alternative to transanal endoscopic microsurgery (TEM). The TAMIS technique can be access to the proximal and mid-rectum for resection of benign and early-stage malignant rectal lesions and also used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery. TAMIS has a shorter learning curve, reduced device setup time, flexibility in instrument use, and versatility in application than TEM.

Successful treatment of basaloid squamous cell carcinoma in the rectosigmoid colon: A case report and review of literature.

Background: Compared with colorectal adenocarcinoma, basaloid squamous cell carcinomas (BSCCs) arising in the colorectum are rare and have very poor prognosis. To date, only nine cases have been reported. Most BSCCs are extensively involved in metastasis to the lymph node, liver, and lung at diagnosis.

Penile metastasis in rectal cancer with pathologic complete response after neoadjuvant chemoradiotherapy: The first case report and literature review.

Rationale: Penile metastasis in rectal cancer is very rare and often originates from prostatic or bladder cancer. The prognosis of penile metastasis is poor and its treatments are more often palliative than curative due to association with disseminated metastases. Pathologic complete response (pCR) in rectal cancer with neoadjuvant chemoradiotherapy (CRT) has been shown to be surrogate marker of favorable long-term outcomes and currently has no report of penile metastasis.

Extent of Pedigree Required to Screen for and Diagnose Hereditary Nonpolyposis Colorectal Cancer: Comparison of Simplified and Extended Pedigrees.

Background: Obtaining an accurate pedigree is the first step in recognizing a patient with hereditary nonpolyposis colorectal cancer, or Lynch syndrome. However, lack of standardization of the degree of relationship included in the pedigrees generally limits obtaining a complete and/or accurate pedigree.

Design: This study analyzed the extent of pedigree required to screen for colorectal cancer and to diagnose Lynch syndrome.

Effects of an Internet-based informational video on preoperative anxiety in patients with colorectal cancer.

Purpose: Surgery is the primary curative treatment for colorectal cancer; however, it remains a frightening procedure that can cause stress and pain in affected patients. Therefore, patients typically experience significant anxiety during the preoperative period, which has been associated with poorer outcome after surgery. This study aimed to evaluate the effect of an Internet-based informational video on preoperative anxiety level in patients with colorectal cancer.

Resting vector volume measured before ileostomy reversal may be a predictor of major fecal incontinence in patients with mid or low rectal cancer: a longitudinal cohort study using a prospective clinical database.

Purpose: Despite a high incidence of fecal incontinence following sphincter-preservation surgery (SPS), there are no definitive factors measured before ileostomy reversal that predict fecal incontinence. We investigated whether vector volume anorectal manometry before ileostomy reversal predicts major fecal incontinence following SPS in patients with mid or low rectal cancer.

Methods: This longitudinal prospective cohort study comprised 173 patients who underwent vector volume anorectal manometry before ileostomy reversal.

Oncologic evaluation of obesity as a factor in patients with rectal cancer undergoing laparoscopic surgery: a propensity-matched analysis using body mass index.

Purpose: This study evaluated the oncologic impact of obesity, as determined by body mass index (BMI), in patients who underwent laparoscopic surgery for rectal cancer.

Methods: The records of 483 patients with stage I-III rectal cancer who underwent laparoscopic surgery between June 2003 and December 2011 were reviewed. A matching model based on BMI was constructed to balance obese and nonobese patients.

Postoperative Portomesenteric Venous Thrombosis After Colorectal Cancer Surgery.

Background: Portomesenteric venous thrombosis (PMVT) can occur after colorectal surgery. Most previous studies included patients with various diseases, especially inflammatory bowel disease. The prevalence and clinical significance of PMVT developing after surgery for colorectal cancer (CRC) remain unclear.

Discrepancy of Medical Terminology Regarding Colorectal Surgery Between South and North Korea.

Purpose: We aimed to investigate the extent of heterogeneity in medical terminology between South and North Korea by comparing medical terms related to the colorectal system.

Methods: North Korean medical terms were collected from the sections on diseases of the small intestine and colon in a surgery textbook from North Korea, and those terms were compared with their corresponding terms in a South Korean medical terminology textbook. The terms were categorized as either identical, similar, showing disparity, or not used in South Korea.
