Filter by:The goal of this clinical trial is to learn about clinical usefulness endoscopic gastrointestinal anastomoses to restore the gastrointestinal continuity in patients with permanent colostomy after Hartmann procedure. The main questions it aims to answer are: - is the endoscopic restore the gastrointestinal continuity procedure effective? - is this endoscopic procedure safe?
Background and aims: Cesarean section defect (CSD) can cause abnormal uterine bleeding or impaired fertility, which severely impaire the quality of life in women of pregnant age. For women with moderate or severe CSD, surgery can be performed. The objectives of this study is to compare the efficacy and safety of different suture methods in the treatment of transvaginal diverticulum resection, and the underlying mechanism of CSD occurrence. Methods: The patients diagnosed with CSD will be enrolled and randomizely assigned into suture method A and suture method. The fresh isolated tissue and swab of different sites in genital tract will be collected for NGS, microbiome, metabonomics and proteomics analysis. Hypothesis: The menstruation will be analyzed at different following time. The other clinical information will be also collected, including age at surgery, skin-to skin operative time, estimated blood loss (EBL). The perioperative complications, postoperative hopitalization, cost for hospital stay, blasser/intestinal function recovery will also be compared between two gorup. The outcome of fertility will be compared, such as the premature birth, premature rupture of membranes, and rupture of uterus. The clinical manifestation related to CSD and recurrence will be followed. Besides, the underlying mechanism will be analyzed.
The study compares the microbiome differences in the endometrium between normal people and patients with uterine diverticula after cesarean section and aims to discover the essential microbes and their metabolites that highly associate with the repair of myometrium through metagenomics and metabolomics. It verifies that flora disorder in the endometrium is the important cause of poor uterine repair after cesarean section. Then these patients with uterine diverticula receive the transvaginal repair surgery. Through the follow-up with them, we gain the microbiome differences of the endometrium before and after the surgery and show the validity of transvaginal repair surgery in the level of microbiome and metabolism.
Acute diverticulitis of the left colon is among the most common abdominal disorders. To date, both conservative therapy in uncomplicated stages and emergency surgery in perforated disease with peritonitis are consensual. The best treatment strategy for other situations (i.e., smoldering, healed abscesses, recurrences) is still under debate. On the other hand, the best treatment strategy for complicated disease as well as for recurrent stages is still under debate. In these cases, elective surgery can be proposed on a case-by-case basis. Current French guideline recommendations have been updated in 2017. In theory, the objective of elective surgical treatment is to prevent the recurrence and/or complication of the diverticulitis, that might lead to the creation of a stoma. In France, nearly 12,000 prophylactic colectomies for diverticulitis are performed per year. Importantly, elective surgical treatment is associated with the relevant intrinsic morbidity (9.6% major complications within the Sigma Trial), the potential need for unplanned stoma formation of 1%-14% and a significant risk of persisting postoperative complaints. Up to 25% of patients who have undergone a scheduled sigmoid colectomy suffer from ongoing abdominal symptoms. Levack et al found the risk of faecal incontinence to be 24.8% after a sigmoidectomy. Moreover, faecal urgency occurred in 19.6% of patients, and incompleteness of emptying occurred in 20.8%., altering their quality of life (QOL). To out knowledge, few data are available in the literature concerning the evaluation of QOL after elective sigmoid colectomy. Although QOL was significantly improved after surgery compared to conservative medical treatment, these results were questionable due to the heterogeneity of the studies and the lack of direct comparison of the two therapeutic approaches. Only one recent randomized study reported similar results but this one was prematurely stopped due to inclusion difficulties. The evaluation of digestive and genitourinary functional sequelae is based only on short series, most often retrospective. In summary, evidence on disease-specific characteristics influencing postoperative quality of life is lacking. The aim of this prospective multicenter study is : (i) to evaluate the QOL and functional sequelae at 6 and 12 months in patients operated on for elective left colectomy and, (ii) to compare them to a population of non-operating diverticulitis patients.
The Zenker's or pharyngo-esophageal diverticulum is an acquired sac-like outpouching of the mucosa and submucosa layers located dorsally at the pharyngoesophageal junction through Killian's dehiscence. It is the most common type of oesophageal diverticula and typically occurs in middle-aged and elderly patients. Patients have a significantly reduced quality of life index and numerous complications. Treatment is recommended for symptomatic patients and considering the aetiopathogenesis of the disease demands myotomy of the cricopharyngeal muscle. Myotomy may be pursued through either open surgical or endoscopic techniques. There is a novel technique, called the peroral endoscopic myotomy (Z-POEM) for treatment of Zenker's diverticulum. The ZIPPY trial designed as prospective, international, multicenter, double-blind, randomized study which will be carried out by experienced endoscopists. The aim of this study will be to evaluate the results of Zenker's diverticulum treatment using peroral endoscopic myotomy and to compare its efficacy and safety to flexible endoscopy septotomy. Patients at least 18 years old with symptomatic Zenker's diverticulum diagnosed on the basis of endoscopic and radiological examinations will be enrolled.
The mechanical bowel preparation (BP) used to clean the colon prior to colonoscopy frequently results in a significant but temporary reduction in patient's symptoms for a number of bowel disorders including symptomatic uncomplicated diverticular disease. The cause of this improvement is unknown. We hypothesise that changes to the gut microbial population (microbiota) are responsible for this improvement and that the repopulation of the GI tract with bacteria following colonoscopy results in a return of their normal symptoms. This pilot study will test this in a preliminary way by examining the stool, urine and blood of patients before and after bowel preparation to detect any destabilising effect that BP has on the gut microbiota and to what extent the microbiota repopulates at 3 months If the hypothesis is proven, this study will show that BP generates a 'window of opportunity' in which to influence the subsequent re-establishment of the microbiota. This is with the eventual aim of correcting potential dysbiosis and preventing the progression of symptomatic uncomplicated diverticular disease (SUDD).
Cesarean scar diverticula (CSD) is a novel recognized cause of postmenstrual abnormal uterine bleeding in women. No clinical guidelines have been issued for the management of CSD. Currently, several limited surgical management procedures for CSD have been reported, such as hysteroscopic combined with laparoscopic excision (abbreviated as hysteroscope + laparoscope) and vaginal repair of CSD (abbreviated as VR). However, which management can achieve better clinical effects remains unknown. Therefore, this prospective study is designed to compare the therapeutic effects between VR and hysteroscope + laparoscope in the treatment of CSD.
Cesarean scar diverticula (CSD) is a novel recognized cause of postmenstrual abnormal uterine bleeding in women. No clinical guidelines have been issued for the management of CSD. The investigators have previously demonstrated that vaginal repair of CSD was an relative effective treatment of CSD. However, only 28.2% of the CSD patients normalized to less than 7 days of menstruation, whereas 51.2% of women had 7 to 10 days of menstruation at 6 months post vaginal repair. Postoperative menstruation may contribute to surgical site infections, which may subsequently affect the healing of uterine scars. Treatment CSD patients with gonadotropin-releasing hormone agonist (GnRHa) may has the potential to improve therapeutic effects of vaginal repair. Therefore, the current multiple-center randomized controlled trial was designed to evaluate whether the application of GnRHa in combination with vaginal repair could achieve better clinical effects than those achieved by vaginal CSD repair alone.
Colonic diverticular disease is a highly prevalent condition in Western populations. The prevalence increases age-dependently from 5% at 40 years to 65% by the age of 85 years (1-3). The majority remain asymptomatic. However, a significant proportion of the patient population develops complications, such as diverticulitis with or without symptoms (10-20%) (1, 4-10). Perforated diverticulitis is rare with an estimated incidence of 4 per 100.000 per year, but the associated mortality rate is 22% to 39% (9, 11, 12). In the United States, the complications related to diverticular disease account for 130.000 hospitalizations each year, resulting in substantial health care costs (13). In Europe, it is estimated that approximately 23.600 deaths per year can be attributed to complicated diverticular disease, and the mortality will probably increase in the future due to the aging population (15-17). Several case studies report an overall increase in the incidence of diverticulitis, based on the increase in hospitalizations (18). Kang et al, reported a 16% increased male admission rate and 12% female admission rate for diverticulitis, between 1989/1990 and 1999/2000 (19). Aging and the Western diet, low in fiber and high in fat, in combination with increased intraluminal pressure and alterations in colonic motility are considered important etiological factors. A disturbance in large bowel motility is suggested to be a common pathophysiological feature in IBS and diverticular disease (20, 21). Based on observations that IBD, subgroups of IBS and (symptomatic) diverticular disease share clinical symptoms, the hypothesis is derived that they might also share pathophysiological factors like low grade inflammation, changed microbiota composition and activity, and increased intestinal permeability. The identification of clinical and pathophysiological factors associated with an increased risk for complicated diverticular disease may help to identify patients with diverticular disease, prevent complications, develop strategies to improve quality of life and reduce the related health care costs. Therefore we aim to investigate the composition of luminal and mucosal intestinal microbiota and the intestinal permeability in the development of diverticular disease and complicated diverticular disease. We hypothesize that both the intestinal microbiota and intestinal permeability are altered in patients with (current- or previous history of complicated) diverticular disease.
