Filter by:The SCI-Pex study is a multicenter, prospective, non-controlled investigation on PexyEazy®, a new device for treatment of hemorrhoids based on the mucopexy method. Mucopexy is a well established method where sutures are applied above the hemorrhoids. When knots are tied, the hemorrhoids are lifted inwards to their normal position, which makes them swell down and symptoms disappears. PexyEazy® perform a mukopexy in a semiautomatic, faster and easier way on awake patient in less than 10 minutes. The SCI-Pex study will evaluate the safety and performance of PexyEazy on 35 patients with hemorrhoids grade II and III with a follow-up after 1 week, 3 months and 5 years. Adverse events, pain and other complications will be recorded, quality of life and hemorrhoid symptom questionnaires and clinical examination after 3 months will be monitored to evaluate the result after a PexyEazy® procedure.
The treatment of rectal cancer is currently based on surgical resection of the rectum with total excision of the mesorectum, associated with neoadjuvant radiochemotherapy. Surgical resections with sphincter preservation are frequently (60% of cases) associated with problems related to intestinal and defecatory function, which together are called Anterior Resection Syndrome (ARS) with varying degrees of severity. Among the different treatments the investigators find posterior tibial nerve stimulation, a simple and non-invasive technique, which is currently used. The study aims to analyze whether postoperative posterior tibial nerve stimulation in patients undergoing low anterior resection of the rectum has an impact on the incidence and duration of low anterior resection syndrome (LARS) and therefore on the quality of life of patients undergoing this type of intervention. Therefore, treatment with PNTS is currently established for the management of LARS symptoms. Given that a large percentage of patients operated on for rectal neoplasms will develop this syndrome, the investigators intend to apply this treatment before the onset of symptoms in patients at risk for LARS. It is also an intervention with a low rate of side effects, the benefit that the investigators can obtain from its preventive application is clearly superior to the risk of undergoing such treatment. The investigators´ hypothesis is: Posterior tibial stimulation for 6 weeks post-operative of low anterior resection with anastomosis has a favorable impact by reducing the incidence and duration of ARS and improving the quality of life of patients undergoing anterior rectal resections for cancer.
Currently, the question remains whether palliative primary tumor resection could improve overall survival of minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases. The aim of this study is to determine if there is an improvement in overall survival of palliative primary tumor resection followed by chemotherapy in minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases compared to those of upfront chemotherapy/radiotherapy alone.
Rationale: Haemorrhoidal disease is one of the most common anorectal disorders which affects nearly half of the general population1. Given the current numerous modalities the obvious question which needs to be answered is which treatment is the best. An interesting conclusion from a recent systematic review regarding operative procedures for haemorrhoidal disease is that all procedures have their own advantages and disadvantages. There is a need for evaluating treatment from the patient's point of view and transparency in surgical and non-surgical treatment outcome. So far there is no sufficiently large trial that meets that demand. Objective: To establish the best treatment of patients with symptomatic haemorrhoids grade III: haemorrhoidectomy versus rubber band ligation (RBL). Patient bound effectiveness, clinical effectiveness and cost-utility of both treatments is compared; primary outcome is quality of life at 24 months measured with the EQ-5D-5L with Dutch rating and recurrence at one year post procedure. The assumption is that treatment with rubber band ligation is equally effective in comparison with haemorrhoidectomy in terms of quality of life. Study design:Multicentre randomized controlled non-inferiority trial with cost-utility analysis. Two treatment protocols are compared: haemorrhoidectomy and rubber band ligation. Study population: Patients aged ≥ 18 years with symptomatic haemorrhoids gr III. Patients are recruited in multiple clinics during 18-24 months. Intervention: Participants are allocated to either rubber band ligation or haemorrhoidectomy. Main study parameters/endpoints: Primary outcome measure is quality of life at 24 months measured with the EQ-5D-5L with Dutch rating and recurrence at one year post procedure. Secondary outcomes are: complaint reduction with proctology specific patient-related outcome measure (HSS, PROM, PROMHISS), vaizey score, resumption of work, pain (VAS), complications and recurrence at two years.
IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.
The first objective to determinate the prevalence of pelvic floor dysfunction in pregnant women and in the first year postpartum. The second objective is to assess the anatomical (both clinical and ultrasound), demographic and obstetric variables in symptomatic women and their association with pelvic floor dysfunction, sexual function and Body Image. This is a single center prospective cohort study. Women will be asked to fill out a questionnaire at the time of their 1st and 3rd trimester scan, at the postpartum checkup and 12 months postpartum. Furthermore, they will undergo a pelvic floor ultrasound at the time of their first and third trimester scan. The presence of pelvic floor dysfunctions will be recorded through validated self-administered questionnaires with five domains: Wexner questionnaire for anal incontinence, PAC-SYM for constipation, International Consultation on Incontinence Questionnaire Short Form for urinary incontinence, the Pelvic Organ Prolapse Distress Inventory for pelvic organ prolapse, POP/UI Sexual Questionnaire - IUGA revised for sexual function. The body image perception will be assessed using the Dutch-validated version of the self-administered Body Image Disturbance Questionnaire. The anatomy of the pelvic floor will be objectively assessed off line on 3D/4D transperineal ultrasound volumes and POP-Q examination. The demographic variables and information about the pregnancy and the delivery will be obtained from the medical records.
Up to now, many studies has showed that compared with air insufflation colonoscopy, water-related colonoscopy could shorten the cecal intubation time and relieve the pain of the patients,especially for training the beginners,the investigators conduct this study to preform the "air assisted" water injection colonoscopy in experienced endoscopists.
Water injection colonoscopy has been a generally accepted method in training the beginners of colonoscopy for its low pain and less cecal intubation time, we would conduct this study to investigate more advantages of this method and make most use of it for beginners' training.
