Operation with appendectomy for appendiceal mass carries a high risk of complications compared with conservative treatment or drainage .
Drainage may lower the risk of treatment failure but entails a risk of complications .
INTRODUCTION The treatment strategy for appendiceal mass is controversial , ranging from operation or image-guided drainage to conservative treatment with or without antibiotics .
The aim of this study was to assess the various treatment modalities with respect to complications and treatment failure .
Long-Term Outcome of Mesocolic and Pelvic Diverticular Abscesses of the Left Colon: A Prospective Study of 73 Cases
PURPOSE The aim of of this study was to evaluate prospect ively the long-term outcome of mesocolic and pelvic diverticular abscesses of the left colon . METHODS Between October 1986 and October 1997 , a total of 465 patients urgently admitted to our hospital with a suspected diagnosis of acute left-sided colonic diverticulitis had a CT scan .  Of 76 patients ( 17 percent ) who had an associated mesocolic or pelvic abscess , 3 were lost to follow-up . The remaining 73 patients ( 45 with a mesocolic abscess and 28 with a pelvic abscess ) were followed for a median of 43 months . RESULTS of the 45 patients with a mesocolic abscess , 7 ( 15 percent ) required surgery during their first hospitalization versus 11 ( 39 percent ) of the 28 patients with a pelvic abscess ( P = 0.04 ) . At the end of follow-up , 22 ( 58 percent ) of the 38 patients with a mesocolic abscess who had successful conservative treatment during their first hospitalization did not need surgical treatment vs. 8 ( 47 percent ) of the 17 who had a pelvic abscess . Altogether , 51 percent of the patients with a mesocolic abscess had surgical treatment versus 71 percent of those with a pelvic abscess ( P = 0.09 ) . CONCLUSIONS Considering the poor outcome of pelvic abscess associated with acute left-sided colonic diverticulitis , percutaneous drainage followed by secondary colectomy seems justified . Mesocolic abscess by itself is not an absolute indication for colectomy
