Indocyanine Green Fluorescence Imaging in Prevention of Colorectal Anastomotic Leakage
Colorectal CancerColorectal Neoplasms5 moreThis is a randomized, controlled, parallel, multicenter trial to determine the difference in post-operative anastomotic leakages in colorectal surgery, where anastomosis perfusion is evaluated using indocyanine green fluorescence imaging as an addition to standard surgical practice compared to surgical practice alone.
Outpatient Left Laparoscopic Colectomy
Colonic NeoplasmsColonic DiverticulosisThe success of the enhanced recovery program after surgery leads us to consider outpatient management of the colectomy. To this end, the investigators have designed an observational and prospective study of left laparoscopic colectomy on an outpatient basis. The objective is to assess the harmlessness of this management compared to standard management in the context of a public hospital.

Mechanistic Randomized Controlled Trial (RCT) of Mesalazine in Symptomatic Diverticular Disease...
DiverticulosisColonicDiverticulosis (bulges in the bowel wall) affects two third of the elderly population in the UK. Diverticular disease and its complications are responsible for 68000 hospital admissions and 2000 deaths per year. It commonly produces recurrent short lived abdominal pain, changes in bowel habit and incontinence. The causes of symptoms are not known and the treatments unsatisfactory. Recent studies have found an association between inflammation, alteration of bowel nerves and symptoms. Mesalazine is an anti-inflammatory drug used in inflammatory bowel conditions, such as ulcerative colitis and crohn's disease. We plan to perform a randomized double blind (neither the patients or the doctors known which treatment the patient is taking) placebo (sham medication) controlled trial of mesalazine in symptomatic diverticular disease patients. We anticipate a reduction in the amount of inflammation, bowel nerve changes and symptoms in patients taking mesalazine compare to those taking the placebo.

Transversus Abdominis Plane (TAP) Block for Postoperative Analgesia After Laparoscopic Colonic Resection...
Colonic CancerRectal Cancer2 moreLaparoscopic (key-hole) large bowel resection is a minimally invasive procedure when compared to open large bowel resection, but is still associated with a significant amount of pain and discomfort. Analgesia is commonly provided by a multi-modal technique involving varying combinations of paracetamol, Non steroidal anti-inflammatory drugs (NSAIDs), regional analgesia and oral or parenteral opioids. While epidural analgesia is considered the gold standard for open colo-rectal procedures it can be associated with significant complications and may delay hospital discharge in laparoscopic procedures. Opioids are associated with an increased incidence of nausea, vomiting and sedation and reduced bowel motility which can also prolong recovery. Transversus Abdominis Plane (TAP) block is a technique which numbs the nerves carrying pain sensation from the abdominal wall and provides effective and safe analgesia with minimal systemic side effects. Their perceived benefits are thought to relate to reduced opioid consumption and therefore reduced opioid side effects. The investigators believe ultrasound guided TAP blocks will reduce pain and morphine consumption with a resultant improved patient satisfaction, earlier return of bowel function and earlier hospital discharge. The key research question the investigators are trying to answer is whether TAP block provide better pain relief than local anaesthetic infiltration of the laparoscopic port sites. Both techniques are currently being used in our hospital and a retrospective audit demonstrated better analgesia and lower consumption of morphine in the TAP block group.The differences were not statistically significant as the number patients in the audit were not large enough.The investigators are hoping that this study will demonstrate that the difference is real by recruiting the necessary number of patients into each group (36 per group)
Prophylactic Elective Clipping of Colonic Diverticula
Diverticular DiseaseDiverticular 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.
