Active clinical trials for "Diverticulum"

The aim of the present study was to evaluate whether antibiotics is mandatory for the treatment of acute uncomplicated right-sided diverticulitis. The hypothesis is that patients having acute uncomplicated diverticulitis at right-sided colon will be recovered without antibiotics.

Historically, percutaneous treatment of stone-bearing caliceal diverticula has resulted in the best success rates when examining factors such as symptom relief and stone-free rates (Jones, et al, 1991). Many groups have reported modifications in their percutaneous approach which have reportedly improved patient outcomes, but these series have very limited populations. Another issue concerning stone-bearing caliceal diverticula centers on the etiology of stones formation within these areas. This topic remains a subject of debate, with conflicting data in the literature.

Cesarean section accounts for nearly 30% of births in Canada, and is the most commonly performed surgery by Obstetrician Gynecologists. Cesarean scar isthmocele, meaning a defect in the uterine wall at the site of a previous uterine incision, is a common complication of this surgery. While most are likely asymptomatic, isthmoceles can lead to major complications in pregnancy (uterine rupture, invasive placentation, cesarean scar ectopic pregnancy) and outside of pregnancy (abnormal uterine bleeding, infertility and pain). Studies have shown that the method used to suture the uterus at the time of a cesarean section may have an impact on the incidence of post-operative isthmocele formation. Our study is a randomized control trial of the impact of locked vs unlocked uterine closure at cesarean section on the incidence of isthmocele formation. Women undergoing cesarean section will be randomized to have either a locked or unlocked uterine closure. They will then return 6 months after their surgery for a transvaginal ultrasound to evaluate the presence or absence of an isthmocele. This study is a pilot trial. The investigators hope to determine the feasibility of completing a large randomized control trial by recording: a) the number of patient who agree to participate in this study, b) the number of patients who receive the correct intervention and, c) the number of patients who return for their post operative ultrasound. The investigators also plan to assess multiple secondary outcomes. First, the goal is to determine the isthmocele incidence within the study subjects of the pilot trial in order to perform a power calculation for a subsequent larger trial in this area. Another goal is to determine if the uterine closure techniques in this study lead to differences in surgical time, blood loss or the need for intra- or post-operative blood transfusion. Last, the study will collect data on the suture material most commonly used in this study to determine if this requires standardization in the subsequent larger trial.

The aim of this study is to evaluate the ability of a ICG-fluorescence guidance complemented with enhanced reality to correctly document intestinal pre-anastomotic perfusion and to validate the accuracy of this technique with metabolic intestinal cells changes.

The purpose of this study is to see if people with reflux with a Zenker's diverticulum have increased reflux into the throat following a cricopharyngeal myotomy.

Diverticular disease is a chronic pathology, characterized by recurrent abdominal symptoms and a high social impact, with a high prevalence in developed countries, especially among the elderly. Diverticula are thought to develop from age-related degeneration of the mucosal wall and segmental increases in colon pressure resulting in bulging at points of weakness, typically at the insertion of the vasa recta. Classification of diverticular disease is largely based on symptoms: it begins with the development of diverticulosis, to asymptomatic disease, to symptomatic uncomplicated diverticular disease (SUDD) and finally to complicated disease when patients develop abscesses, phlegmon, bleeding, fistula and sepsis. Approximately the 20% of the patients with diverticular disease has symptoms, such as abdominal pain, fever and altered bowel movement and, in the last decades, a significant increase of the incidence of complications related to the disease has been recorded, in particular of intestinal perforation. Lactoferrin (Lf) is a glycoprotein present in several secretory liquids - i.e. milk, saliva and tears - with antimicrobial properties that it exert to seizing iron, thus preventing the use by the pathogens, or altering their plasma membrane through its highly cationic charge. The investigators hypothesize that the antimicrobial and immunoregulatory characteristics of the Lf can be used to maintain an adequate homeostasis of the intestinal mucosa in patients with SUDD resulting in an improvement of both symptoms and quality of life.

Conventional multi-port laparoscopic surgery (CL) is now a standard approach to colorectal resections, due to it's short-term benefits over conventional open surgery. In recent years, several studies have demonstrated that - in suitable patients - single-port access surgery (SPA) has similar clinical outcome compared to CL, with additional cosmetic benefits. It remains, however, unclear whether the trauma of surgery is also less for SPA compared to CL. In this study, the investigators aim to randomise patients who are deemed suitable for SPA surgery to either SPA approach, or CL; in addition to clinical outcomes including length of operating time, post-operative pain scores, complications, quality of life indicators and cosmetic appearance, the investigators aim to compare the physiological response to trauma through biochemical markers (including C-reactive protein, White Blood Cell count) and cytokine expression (i.e. Interleukins IL-6 and IL-8). Patients will be analysed according to intention-to-treat analysis, with 25 patients in the SPA and 25 patients in the CL group. The patients will be operated by surgeons proficient in both CL and SPA surgery, and followed-up for the duration of their hospitalisation as well as at their routine out-patient visits, using questionnaires.

The purpose of this study is to evaluate the short-term effect of sealant-assisted skin closure in prevention of surgical site infection after laparoscopic surgery.

In this study, our novel MRI techniques for studying the small bowel will be applied to patients with diverticular disease. The ratio of visceral to subcutaneous fat will also be determined using MRI measurements. These data will be correlated with measurements of adipokines to determine if visceral fat has a specific influence on the severity of diverticular disease.

Enhanced recovery after surgery (ERAS) protocols are programs aiming to implement patients recovery following surgical procedures developed about 25 years ago. ERAS protocols are based on a multi-disciplinary approach encompassing surgery, anesthesiology, nutrition and nursing; each specialty has to fulfill a number of items which have been demonstrated to reduce morbidity rates, hospital stay and to implement functional recovery comparing standard approach. Accordingly, ERAS society developed a Guidelines for a number of procedures, including colorectal. The aim of this study is to evaluate the adherence over the last years to these protocols in eight Department of Surgery in Rome in a series of colorectal cancer patients. Secondary aims are to investigate the correlation of the items adherence with surgical outcome and to establish a network of hospitals aiming to promote ERAS approach on a regional base.
