- W2917961528 abstract "Abstract Background Treatment strategies for diverticulitis with abscess formation have shifted from (emergency) surgical treatment to non-surgical management (antibiotics with or without percutaneous drainage (PCD)). The aim was to assess outcomes of non-surgical treatment and to identify risk factors for adverse outcomes. Methods Patients with a first episode of CT-diagnosed diverticular abscess (modified Hinchey Ib or II) between January 2008 and January 2015 were included retrospectively, if initially treated non-surgically. Baseline characteristics, short-term (within 30 days) and long-term treatment outcomes were recorded. Treatment failure was a composite outcome of complications (perforation, colonic obstruction and fistula formation), readmissions, persistent diverticulitis, emergency surgery, death, or need for PCD in the no-PCD group. Regression analyses were used to analyse risk factors for treatment failure, recurrences and surgery. Results Overall, 447 patients from ten hospitals were included (Hinchey Ib 215; Hinchey II 232), with a median follow-up of 72 (i.q.r. 55–93) months. Most patients were treated without PCD (332 of 447, 74·3 per cent). Univariable analyses, stratified by Hinchey grade, showed no differences between no PCD and PCD in short-term treatment failure (Hinchey I: 22·3 versus 33 per cent, P = 0·359; Hinchey II: 25·9 versus 36 per cent, P = 0·149) or emergency surgery (Hinchey I: 5·1 versus 6 per cent, P = 0·693; Hinchey II: 10·4 versus 15 per cent, P = 0·117), but significantly more complications were found in patients with Hinchey II disease undergoing PCD (12 versus 3·7 per cent; P = 0·032). Multivariable analyses showed that treatment strategy (PCD versus no PCD) was not independently associated with short-term treatment failure (odds ratio (OR) 1·47, 95 per cent c.i. 0·81 to 2·68), emergency surgery (OR 1·29, 0·56 to 2·99) or long-term surgery (hazard ratio 1·08, 95 per cent c.i. 0·69 to 1·69). Abscesses of at least 3 cm in diameter were associated with short-term treatment failure (OR 2·05, 1·09 to 3·86), and abscesses of 5 cm or larger with the need for surgery during short-term follow-up (OR 2·96, 1·03 to 8·13). Conclusion The choice between PCD with antibiotics or antibiotics alone as initial non-surgical treatment of Hinchey Ib and II diverticulitis does not seem to influence outcomes." @default.
