As cancer survival rates have been increased due to technological developments and early detection strategies, there has been been a growing need to assess the effect of long-term complications and adverse effects upon patients' functionality and quality of life. Chemotherapy, which is accepted to be the body of systemic adjuvant therapy is attributed to long-term survival, yet some side effects such as sarcopenia, loss of muscle strength and functional capacity, fatigue, and sensory disturbances due to the neurotoxic effects have been well known. Chemotherapy-induced peripheral neuropathy (CIPN) is a condition that is characterized by main loss of cutaneous sensation especially in the distal part of the extremities. CIPN affects approximately 30-40% of patients with cancer undergoing chemotherapy. Loss of sensation in distal sides of upper and lower extremities may cause not only deterioration of fine hand skills but also loss of balance and thereby one's mobility and independence are detrimentally affected. Thus, this study is aimed to assess CIPN in patients with cancer undergoing chemotherapy in a longitudinal design by assessing the cutaneous function of the sensory nerves and related effect of motor function.
An international, multicenter study to identify tumor molecular particularities and neoepitopes among participants with colorectal and pancreatic tumors undergoing surgery.
The aim of the study is to compare ADR for colonoscopies from various indications and to find correlations between ADR of screening and all examinations.
The aim of our study is to compare MAP (mean adenoma per colonoscopy) with ADR (adenoma detection rate) and PDR (polyp detection rate) of all colonoscopists in our department
The GEPOC study investigates the effect of comprehensive geriatric assessment and intervention for frail older patients (65 years or older) undergoing elective surgery for colorectal cancer. the geriatric intervention will be pre- and postoperative. included in the intervention is an exercise intervention. The main aim of the study us to see if the functional decline in this group can be reduced.
This prospective, randomized controlled trial compares traditional air insufflation with water immersion and water exchange in patients undergoing colonoscopy using on demand sedation. We test the hypothesis that compared with air insufflation the proportion of patients who require on demand sedation during colonoscopy will be significantly lowered by water immersion and water exchange, and water exchange will produce the greatest reduction
In minimally sedated Asian patients in a community setting the investigators showed that a limited volume of water infusion instead of air insufflation in either the rectal sigmoid colon or the whole colon significantly reduced pain score during colonoscopy. Cecal intubation rate was not compromised. The reduction of pain score ranges from 25% to 32 % in our previous studies.1, 2 In contrast, several US reports described the successful use larger volumes of water infused throughout the entire colon in patients undergoing colonoscopy which result in a greater reduction of the pain score, averaging about 56%.3-5 A recent review suggested that the cause of the difference might lies in the timing of water removal.6 Specifically, the investigators group removed the infused water predominantly during withdrawal phase (water immersion) and the U.S. group removed water during insertion phase (water exchange). This prospective, randomized controlled trial compared water exchange or water immersion with traditional air insufflation in patients undergoing minimally sedated colonoscopy. The investigators test the hypothesis that water exchange can reduce more pain than water immersion in the investigators clinical setting.
Colorectal cancer (CRC) is the leading cause of cancer death not only in the Western countries but also in Taiwan. Colonoscopy is now gradually accepted as one of the powerful tool for colorectal cancer screening. Not only for survey after positive fecal test, it is also applied as primary screening modality for CRC screening.Colon cleansing before colonoscopy thus becomes critically important and inadequate preparation may lead to low diagnostic yield with missed lesions, increased risk of complication and prolonged procedure time. Though the importance of good colon preparation can not be over-emphasized, diet control before colonoscopy and ingestion of large amount of lavage solution remain a significant hurdle to overcome and investigators continue to seek for the ideal colon preparation with respect to quality and examinee satisfaction. After the introduction of polyethylene glycol electrolyte lavage solution (PEG-ELS) for bowel preparation before colon procedures, its safety was well documented and the efficacy of colon cleansing was proven efficient. The timing of ingesting PEG-ELS is different between institutes and some ingest PEG-ELS as a whole at the night before colonoscopic examination and some ingested in split-dose manner which ingest half of the solution at previous night and remaining on the day of examination. Some institutes ask examinee to receive lavage solution on the day of examination. The manufacturer advices start taking medication on the day before the investigation according to their printed instruction on the package of PEG-ELS. Though there were a lot of studies that conducted to describe the result of colon cleansing in different fashion, the result is still controversial. This prospective, randomized, single-blinded trail evaluated and compared the efficacy of colon preparation at two timing of colon preparation, namely, in previous night or on the day of colonoscopic examination. In this study, we enrolled those who have already colon neoplasia detected during voluntary routine health check-up and received second colonoscopic examination for either elective polypectomy or endoscopic mucosectomy (EMR). We used not only the cleansing condition as a reference of adequate preparation; we also compared the diagnostic yield of lesion number as an objective comparator between these two methods.
