Filter by:Diverticular bleeding is the most common cause of acute lower gastrointestinal bleeding (LGIB) in Western populations. Although self-limited in 85% of cases, some patients may require hospitalization with blood transfusion and emergent intervention, with significant associated morbidity and mortality. Up to 25% of patients with an initial bleeding episode will have subsequent episodes. Diverticula form at weak points along the colon wall, where the vasa recta enter the circular muscle layer of the colon. Diverticular bleeding is attributed to thinning of the blood vessels as they cross over the dome of a diverticulum. Endoscopic clipping of actively bleeding colonic diverticula has been recognized as a safe and effective treatment for acute LGIB since the mid1990s. Patients selected would have had previous colonoscopy to exclude other causes of bleeding (e.g. angiodysplasia, colorectal cancer). The investigators propose prophylactic elective endoscopic diverticular clipping in patients who have had at least 1 episode of acute LGIB requiring hospitalization. This would involve applying endoscopic clips to the base of every diverticula in a patient's colon, such that any bleeding source would effectively be excluded. The investigators would later reevaluate patients for colonoscopic appearance of diverticula to assess their diverticular disease. The investigators hypothesize that patients undergoing endoscopic diverticular clipping will not have repeat episodes of bleeding.
Diverticulosis of the colon is a frequent condition in adults in western countries and a significant number of patients experience clinical symptoms even when the diverticulosis is not complicated by diverticulitis. Both central and mucosal immunity are altered in Uncomplicated Symptomatic Diverticular Disease (USDD) and Rifaximin ameliorate clinical symptoms and normalize the immunological abnormalities. The Study Protocol is verify the modifications in the immunological pattern induced by reducing bacteria related activation of immunity by Rifaximin treatment.
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 determine whether mesalamine is effective vs. placebo in the prevention of diverticulitis flares in a 24-months follow-up. The primary end-point of the study is the incidence of diverticulitis flares. Will be made a clinical diagnosis of uncomplicated diverticulitis: fever, leukocytosis, abdominal pain and altered intestinal motility.
The aim is to ascertain which method out of epidural, spinal or patient controlled analgesia (PCA) is the most appropriate in fluid optimised patients after laparoscopic colorectal surgery in terms of pain control, length of hospital stay and time for gut recovery. The second aim is to assess the physiological changes that occur when the patient is placed in steep trendelenberg position together with the creation of the pneumoperitoneum.
