Prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwan.

Background: To investigate the prevalence and risk factors of asymptomatic colorectal diverticulosis in Taiwanese general population.

Methods: From January 2009 to December 2011, consecutive asymptomatic subjects undergoing a health check-up were evaluated by colonoscopy. The colorectal diverticulosis was assessed, and a medical history and demographic data were obtained from each subject.

Measurement of peritoneal fluid urea nitrogen and creatinine levels is useful to detect iatrogenic urinary tract leakage in colorectal surgery.

Background: Increased peritoneal drainage after colorectal surgery is a common problem. Measurement of peritoneal fluid urea nitrogen (UN) and creatinine (Cr) is a diagnostic tool to detect the urinary tract leakage (UTL). We evaluated its application in colorectal surgery.

Prevalence and risk factors of asymptomatic colorectal polyps in taiwan.

Purpose. To investigate the prevalence and risk factors of hyperplastic and adenomatous colorectal polyps in a Taiwanese general population. Methods.

Drainage placement through the extraperitoneal tunnel can prevent its postoperative dislodgement effectively in laparoscopic rectal surgery.

Background: Drainage placement is frequently used in laparoscopic rectal surgery, and dislodgement is common in conventional transperitoneal drainage placement. We proposed that extraperitoneal tunnel for drainage placement is useful to prevent the dislodgement.

Methods: We conducted an observational case-matched control study.

Detection of resectable recurrences in colorectal cancer patients with 2-[18F]fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography.

Purpose: To evaluate the usefulness of 2-[(18)F]fluoro-2-deoxy-D-glucose-positron emission tomography/computed tomography (FDG-PET/CT) in the early detection of resectable recurrences of colorectal cancer (CRC) and the impacts on the clinical disease management.

Methods: FDG-PET/CT was performed on patients with elevated serum carcinoembryonic antigen (CEA) levels >5 ng/mL (Group 1) or suspicious recurrences without rise in serum CEA levels (Group 2). The results were analyzed on the basis of histological data, disease progression, and/or clinical follow-up.

Comparison of the feasibility of laparoscopic resection of the primary tumor in patients with stage IV colon cancer with early and advanced disease: the short- and long-term outcomes at a single institution.

Purpose: The role of resection of the primary tumor in patients with stage IV colorectal cancer (CRC) remains controversial. Laparoscopic resection has become an accepted therapeutic option for treating early stage I-III CRC; however, it has not been evaluated for use in patients with advanced stage disease.

Methods: We conducted a retrospective observational study to evaluate the feasibility of laparoscopic resection of the primary tumor exclusively in patients with stage IV colon cancer compared to open resection in patients with stage IV colon cancer and laparoscopic resection in patients with stage I-III colon cancer in terms of operative results and short- and long-term outcomes.

Oxaliplatin-induced severe anaphylactic reactions in metastatic colorectal cancer: case series analysis.

Aim: To investigate oxaliplatin-induced severe anaphylactic reactions (SAR) in metastatic colorectal cancer in a retrospective case series analysis and to conduct a systemic literature review.

Methods: During a 6-year period from 2006 to 2011 at Kaohsiung Veterans General Hospital, a total of 412 patients exposed to oxaliplatin-related chemotherapy were retrospectively reviewed. Relevant English-language studies regarding life-threatening SAR following oxaliplatin were also reviewed in MEDLINE® and PubMed® search.

Health-seeking behaviors and sexuality in rectal cancer survivors in Taiwan: associations with spirituality and resourcefulness.

Purpose/objectives: To examine the relationships between two health-seeking behaviors (HSBs), spirituality and resourcefulness, as well as demographics, cancer-related factors, and sexuality indicators, within the context of Schlotfeldt's health-seeking model in rectal cancer survivors.

Design: Secondary analysis, correlational, and cross-sectional.

Setting: A teaching hospital in southern Taiwan.

Factors that influence survival in colorectal cancer with synchronous distant metastasis.

Background: Treatments for the purposes of curing or more effectively managing metastatic colorectal cancer (CRC) are evolving. Our study focused on patients with primary CRC with synchronous distant metastasis, and we analyzed the factors influencing patient survival.

Methods: Data review was conducted retrospectively.

Demographics, cancer-related factors, and sexual function in rectal cancer patients in Taiwan: preliminary findings.

Background: Sexual function has been ignored because survival issues associated with cancer treatment commonly take precedence over sexual issues. Sexual dysfunction remains a recognized complication after cancer treatment despite improvement in survival rates for patients with rectal cancer.

Objective: This study investigated the relationships among demographics (ie, age, gender, education, religion) and cancer-related factors (ie, stage of disease, type of treatment, time since operation, comorbid conditions) and sexual function in patients with rectal cancer.

Factors that influence survival in unresectable metastatic or locally advanced colorectal cancer.

Purpose: Half of patients with colorectal cancer (CRC) have metastasis during the whole course of the disease. Fewer than 10% of those are still alive at 5 years. Locally advanced CRC accounts for 7% to 33% of CRC relapses.

Acute rectocolitis following endoscopy in health check-up patients--glutaraldehyde colitis or ischemic colitis?

Purpose: Acute rectocolitis is a rare complication that follows endoscopy. It could be caused by glutaraldehyde or ischemic injury. The clinical, endoscopic, radiological, and pathological features of glutaraldehyde-induced colitis may mimic those of ischemic colitis.

Shifting to first-line regimen after previous failure of irinotecan and oxaliplatin containing chemotherapies in unresectable metastatic colorectal cancer: a retrospective study of case analysis.

Purpose: Conventional use of FOLFIRI-FOLFOX or the reverse sequence is the optional regimen in metastatic unresectable colorectal cancer (CRC). We present our experience in chemotherapy (C/T) shifting to first-line regimen after previous failure of irinotecan and oxaliplatin containing regimens.

Materials And Methods: A total of 48 patients with metastatic unresectable CRC were examined retrospectively.

Factors that influence 12 or more harvested lymph nodes in early-stage colorectal cancer.

Background: The number of lymph nodes required for accurate staging is a critical component in early-stage (stage A and B) colorectal cancer (CRC). Current guidelines demand at least 12 lymph nodes to be retrieved. Results of previous studies were contradictory in factors, which influenced the number of harvested lymph nodes.
