AGA Clinical Practice Update on Medical Management of Colonic Diverticulitis: Expert Review.

ABSTRACT: Colonic diverticulitis is a painful gastrointestinal disease that recurs unpredictably and can lead to chronic gastrointestinal symptoms. Gastroenterologists commonly care for patients with this disease. The purpose of this Clinical Practice Update is to provide practical and evidence-based advice for management of diverticulitis. We reviewed systematic reviews, meta-analyses, randomized controlled trials, and observational studies to develop 14 best practices. In brief, computed tomography is often necessary to make a diagnosis. Rarely, a colon malignancy is misdiagnosed as diverticulitis. Whether patients should have a colonoscopy after an episode of diverticulitis depends on the patient's history, most recent colonoscopy, and disease severity and course. In patients with a history of diverticulitis and chronic symptoms, alternative diagnoses should be excluded with both imaging and lower endoscopy. Antibiotic treatment can be used selectively rather than routinely in immunocompetent patients with mild acute uncomplicated diverticulitis. Antibiotic treatment is strongly advised in immunocompromised patients. To reduce the risk of recurrence, patients should consume a high-quality diet, have a normal body mass index, be physically active, not smoke, and avoid nonsteroidal anti-inflammatory drug use except aspirin prescribed for secondary prevention of cardiovascular disease. At the same time, patients should understand that genetic factors also contribute to diverticulitis risk. Patients should be educated that the risk of complicated diverticulitis is highest with the first presentation. An elective segmental resection should not be advised based on the number of episodes. Instead, a discussion of elective segmental resection should be personalized to consider severity of disease, patient preferences and values, as well as risks and benefits.

Project description:DESCRIPTION:The purpose of this clinical practice update review is to describe key principles in the diagnosis and management of functional gastrointestinal (GI) symptoms in patients with inflammatory bowel disease (IBD). METHODS:The evidence and best practices summarized in this manuscript are based on relevant scientific publications, systematic reviews, and expert opinion where applicable. Best practice advice 1: A stepwise approach to rule-out ongoing inflammatory activity should be followed in IBD patients with persistent GI symptoms (measurement of fecal calprotectin, endoscopy with biopsy, cross-sectional imaging). Best practice advice 2: In those patients with indeterminate fecal calprotectin levels and mild symptoms, clinicians may consider serial calprotectin monitoring to facilitate anticipatory management. Best practice advice 3: Anatomic abnormalities or structural complications should be considered in patients with obstructive symptoms including abdominal distention, pain, nausea and vomiting, obstipation or constipation. Best practice advice 4: Alternative pathophysiologic mechanisms should be considered and evaluated (small intestinal bacterial overgrowth, bile acid diarrhea, carbohydrate intolerance, chronic pancreatitis) based on predominant symptom patterns. Best practice advice 5: A low FODMAP diet may be offered for management of functional GI symptoms in IBD with careful attention to nutritional adequacy. Best practice advice 6: Psychological therapies (cognitive behavioural therapy, hypnotherapy, mindfulness therapy) should be considered in IBD patients with functional symptoms. Best practice advice 7: Osmotic and stimulant laxative should be offered to IBD patients with chronic constipation. Best practice advice 8: Hypomotility agents or bile-acid sequestrants may be used for chronic diarrhea in quiescent IBD. Best practice advice 9: Antispasmodics, neuropathic-directed agents, and anti-depressants should be used for functional pain in IBD while use of opiates should be avoided. Best practice advice 10: Probiotics may be considered for treatment of functional symptoms in IBD. Best practice advice 11: Pelvic floor therapy should be offered to IBD patients with evidence of an underlying defecatory disorder. Best practice advice 12: Until further evidence is available, fecal microbiota transplant should not be offered for treatment of functional GI symptoms in IBD. Best practice advice 13: Physical exercise should be encourage in IBD patients with functional GI symptoms. Best practice advice 14: Until further evidence is available, complementary and alternative therapies should not be routinely offered for functional symptoms in IBD. This Clinical Practice Update was produced by the AGA Institute.

Project description:BackgroundAcute colonic diverticulitis (ACD) complications arise in approximately 8% to 35% patients and the most common ones are represented by phlegmon or abscess, followed by perforation, peritonitis, obstruction, and fistula. In accordance with current guidelines, patients affected by generalized peritonitis should undergo emergency surgery. However, decisions on whether and when to operate ACD patients remain a substantially debated topic while algorithm for the best treatment has not yet been determined. Damage control surgery (DCS) represents a well-established method in treating critically ill patients with traumatic abdomen injuries. At present, such surgical approach is also finding application in non-traumatic emergencies such as perforated ACD. Thanks to a thorough systematic review of the literature, we aimed at achieving deeper knowledge of both indications and short- and long-term outcomes related to DCS in perforated ACD.MethodsWe performed a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Pubmed/MEDLINE, Embase, Scopus, Cochrane Library, and Web of Science databases were used to search all related literature.ResultsThe 8 included articles covered an approximately 13 years study period (2006-2018), with a total 359 patient population. At presentation, most patients showed III and IV American Society of Anesthesiologists (ASA) score (81.6%) while having Hinchey III perforated ACD (69.9%). Most patients received a limited resection plus vacuum-assisted closure at first-look while about half entire population underwent primary resection anastomosis (PRA) at a second-look. Overall morbidity rate, 30-day mortality rate and overall mortality rate at follow-up were between 23% and 74%, 0% and 20%, 7% and 33%, respectively. Patients had a 100% definitive abdominal wall closure rate and a definitive stoma rate at follow-up ranging between 0% and 33%.ConclusionDCS application to ACD patients seems to offer good outcomes with a lower percentage of patients with definitive ostomy, if compared to Hartmann's procedure. However, correct definition of DCS eligible patients is paramount in avoiding overtreatment. In accordance to 2016 WSES (World Society of Emergency Surgery) Guidelines, DCS remains an effective surgical strategy in critically ill patients affected by sepsis/septic shock and hemodynamical unstability.
