The lifetime prevalence of diverticulitis among patients with div

The lifetime prevalence of diverticulitis among patients with diverticulosis is 10-25%[69]. The IGF-1R inhibitor standard treatment for uncomplicated diverticulitis is bowel rest and antibiotics. Most patients with uncomplicated diverticulitis respond to conservative management. Osimertinib in vitro Two studies found that patients who did not respond to antibiotics within 48

hours were more likely to require prolonged hospital stays for IV antibiotics and/or surgical intervention[71, 72]. Diverticulitis can be complicated by phlegmon, abscess, or free perforation and is generally classified according to modified Hinchey criteria[73]. Approximately 15-20% of cases are associated with abscesses[74]. In cases of uniloculated abscess, the initial treatment is usually percutaneous drainage; although, in small abscesses (< 4 cm), antibiotics have been used as a primary treatment with success rates comparable to drainage[75, 76]. When percutaneous drainage is performed it has success rates of up to 90%[77]. Of importance, the success of percutaneous drainage also seems to be dependent upon location. Ambrosetti and colleagues Volasertib found that compared to mesocolic abscesses, pelvic abscesses were more aggressive, needed earlier drainage, and were more likely to require surgery[78]. Traditionally, patients who present with an abscess or phlegmon then undergo elective surgery to avoid the high risk of recurrence and further complications[71, 73]. Recently

though, some have begun to question the need for operative therapy when initial management with percutaneous drainage and antibiotics is successful[79]. Two authors have found that perforation, which is the most common cause of mortality in complicated diverticulitis, is more

likely to be the initial presentation of disease, rather than a manifestation of recurrence[79, 80]. They concluded that abscesses in complicated diverticulitis might then be adequately managed with antibiotics and drainage alone. While conservative management may be appropriate in uniloculated abscesses, timely initial operative management is required for cases in which abscesses are large, Fludarabine multiloculated, or inaccessible, as well as in cases of free perforation, or diffuse peritonitis. Acute diverticulitis is complicated by free perforation in approximately 1.5% of episodes[81]. The standard procedure in cases of peritonitis is a Hartmann’s procedure. However, the Hartmann’s procedure is associated with significant morbidity and mortality, and while it can be reversed in 3-6 months, 30-70% of patients never undergo reversal[82–86]. Recently, it has been suggested that primary resection and anastomosis should be preferred[83, 86, 87]. Finally, laparoscopic resections for complicated diverticulitis have also been shown to be safe; and, in spite of longer operative times, they are associated with fewer major complications, less pain, and shorter hospital stays[88].
