Despite ongoing research and new drug treatments, abdominal distension within 24 h postoperatively occurs in 8%–28% of all surgeries. We aim to analyze the effectiveness of preventing PGD by preoperatively stimulating Neiguan（PC6）, Zusanli（ST36） and Shangjuxu（ST37） bilaterally twice a day compared with sham-acupuncture treatment and standard treatment.METHODS AND DESIGN： This is a single-center, prospective practical randomized controlled trial. All groups will be given standard treatments. Patients undergoing vascular surgery under GA will be included from the Vascular Surgery Unit in West China Hospital of Sichuan University, China, and divided into three groups. The experimental group will receive routine treatments and acupuncture at PC6, ST36 and ST37 bilaterally with electrical stimulation twice a day for 20 min preoperatively. The sham-acupuncture group will receive pseudo-electroacupuncture at sham acupoints of PC6, ST36 and ST37, which are 1 cun away from the real acupoints. The routine-treatment group will not receive electroacupuncture. The outcomes include the incidence of abdominal distention, abdominal circumference, the degree of abdominal distension, the fi rst time of fl atus and defecation, and hospitalization duration. DISCUSSION： The results from this study will demonstrate whether preoperative electroacupuncture is an effective method for the prevention of PGD in patients undergoing vascular surgery under GA. This study may also provide a standardized acupuncture treatment for reduction of PGD. TRIAL REGISTRATION： This study is registered with the Chinese Clinical Trial Registry： Chi CTR-TRC-13003649.展开更多

文摘BACKGROUND Gastrointestinal endoscopy technology has significantly improved the diagnostic accuracy and the successful treatment of gastrointestinal diseases.However,a series of ethical issues have emerged,such as expanding treatment indications,which affect the fair distribution of medical resources.There is limited research on ethical issues in the field of digestive endoscopy.AIM To investigate the level of ethical awareness among gastrointestinal endoscopy practitioners and analyze the ethical issues involved in gastrointestinal endoscopy technology.METHODS A questionnaire survey was performed to collect relevant data(gender,age,degree of education,professional title,personnel category,the level of understanding medical ethical principles,ethics training and its learning pathways)from gastrointestinal endoscopy practitioners at the Second Hospital of Dalian Medical University and Dalian Friendship Hospital,including licensed physicians and nurses(including trainees and graduate students).RESULTS The majority of gastrointestinal endoscopy practitioners have received training on ethics,but there is still considerable room for improvement in their ethical awareness.Different learning pathways may affect the mastery of ethical principles, and understanding of ethical principles is more easily achieved through hospital ethics institutions.CONCLUSIONTo address the ethical issues in gastrointestinal endoscopy technology, it is necessary to enhance the humanisticeducation of gastrointestinal endoscopy practitioners, incorporate ethical standards into the technology assessmentprocess, and establish a patient-centered diagnostic and treatment model to improve the ethical awareness of practitionersand achieve a balance between technology and ethics.
文摘BACKGROUND： Postoperative gastrointestinal dysfunction（PGD） is one of the most common complications following major surgeries under general anesthesia（GA）. Despite ongoing research and new drug treatments, abdominal distension within 24 h postoperatively occurs in 8%–28% of all surgeries. We aim to analyze the effectiveness of preventing PGD by preoperatively stimulating Neiguan（PC6）, Zusanli（ST36） and Shangjuxu（ST37） bilaterally twice a day compared with sham-acupuncture treatment and standard treatment.METHODS AND DESIGN： This is a single-center, prospective practical randomized controlled trial. All groups will be given standard treatments. Patients undergoing vascular surgery under GA will be included from the Vascular Surgery Unit in West China Hospital of Sichuan University, China, and divided into three groups. The experimental group will receive routine treatments and acupuncture at PC6, ST36 and ST37 bilaterally with electrical stimulation twice a day for 20 min preoperatively. The sham-acupuncture group will receive pseudo-electroacupuncture at sham acupoints of PC6, ST36 and ST37, which are 1 cun away from the real acupoints. The routine-treatment group will not receive electroacupuncture. The outcomes include the incidence of abdominal distention, abdominal circumference, the degree of abdominal distension, the fi rst time of fl atus and defecation, and hospitalization duration. DISCUSSION： The results from this study will demonstrate whether preoperative electroacupuncture is an effective method for the prevention of PGD in patients undergoing vascular surgery under GA. This study may also provide a standardized acupuncture treatment for reduction of PGD. TRIAL REGISTRATION： This study is registered with the Chinese Clinical Trial Registry： Chi CTR-TRC-13003649.

文摘BACKGROUND Colon cancer is one the most common forms of cancer in both sexes.Due to important progress in the field of early detection and effective treatment,colon and rectal cancer survivors currently account for 10%of cancer survivors worldwide.However,the effects of anti-cancer treatments,especially oxaliplatinbased chemotherapy,on the quality of life(QoL)have been less evaluated.Although the incidence of severe chemotherapy-induced neuropathy(CIPN)in clinical studies is below 20%,data from real-world studies is scarce,and CIPN is probably under-reported due to patient selection and the patients’fear that reporting side-effects might lead to treatment cessation.AIM To determine the impact of CIPN on QoL in colorectal cancer patients with a recent history of oxaliplatin-based chemotherapy.METHODS We performed a prospective cross-sectional study in two major Romanian oncology tertiary hospitals—the Regional Institute of Oncology Ia?i(Iasi,Romania)and the Fundeni Clinical Oncology Institute(Bucharest,Romania).All consecutive patients with colon or rectal cancer,undergoing Oxaliplatin-based chemotherapy that consented to enroll in the study,were assessed by means of two questionnaires—the EORTC QQ-CR29(quality of life in colon and rectal cancer patients)and the QLQ-CIPN20(assessment of neuropathy).Several demographical,social,clinical and treatment data were also collected.Statistical analysis was performed by means of SPSS v20.The student t test was used to assess the relationship between the QLQ-CIPN20 and QLQ-CR29 results.Kaplan Meyer-curves were used to report 3-year progression-free survival(PFS)in patients that discontinued chemotherapy vs those that completed the recommended course.RESULTS Of the 267 patients that fulfilled the inclusion criteria in the pre-specified time frame,101(37.8%)agreed to participate in the clinical study.At the time of the enrolment in the study,over 50%of the patients had recently interrupted their oxaliplatin-based chemotherapy,most often due to neuropathy.Almost 85%of the responders reported having tingling or numbness in their fingers or hands,symptoms that were associated with pain in over 20%of the cases.When comparing the scores in the two questionnaires,a statistically significant relationship(P<0.001)was found between the presence of neuropathic symptoms and a decreased quality of life.This correlation was consistent when the patients were stratified by sex,disease stage,comorbidities and the presence of stoma or treatment type,suggesting that neuropathy in itself may be a reason for a decreased quality of life.At the 3 year final assessment,median recurrence-free survival in stageⅢpatients was 26.88 mo.When stratified by completion of chemotherapy,median recurrence freesurvival of stageⅢpatients that completed chemotherapy was 28.27 mo vs 24.33 mo in patients that discontinued chemotherapy due to toxicity,a difference that did not reach statistical significance.CONCLUSION CIPN significantly impacts QoL in colorectal cancer patients.CIPN is also the most frequent reason for treatment discontinuation.Physicians should actively assess for CIPN in order to prevent chronic neuropathy.
