AIM:To study the clinical outcomes of medical therapy in patients with right colonic diverticulitis.METHODS:The records of 189 patients with right colonic diverticulitis which was finally diagnosed by computed tomography,ultrasonography,or operative findings were retrospectively reviewed.RESULTS:Of the 189 patients hospitalized for right colonic diverticulitis,the stages of diverticulitis by a modified Hinchey classification were 26 patients(13.8%)in stage 0,139 patients(73.5%)in stageⅠ a,23 patients(12.2%)in stageⅠb,and 1 patient(0.5%)in stageⅢ.Medical therapy was undertaken in 185 of 189 patients(97.9%).One hundred and eighty three of 185 patients were successfully treated with bowel rest and antibiotics.Two patients in stageⅠb required a resection or surgical drainage because of an inadequate response to conservative treatment.Recurrent diverticulitis developed in 15 of 183 patients(8.2%)who responded to medical therapy.All 15 patients who suffered a second attack had uncomplicated diverticulitis,and were successfully treated with medical therapy.CONCLUSION:Our results indicate that right colonic diverticulitis is essentially benign and imageguided conservative treatment is primarily required.
AIM: To study the clinical outcomes of medical therapy in patients with right colonic diverticulitis. METHODS: The records of 189 patients with right colonic diverticulitis which was finally diagnosed by computed tomography, ultrasonography, or operative findings were retrospectively reviewed .RESULTS: Of the 189 patients hospitalized for right colonic diverticulitis, the stages of diverticulitis by a modified Hinchey classification were 26 patients (13.8%) in stage 0,139 patients (73.5%) in stage I a, 23 patients (12.2%) in stage Ib, and 1 patient (0.5% ) in stage III. Medical therapy was undertaken in 185 of 189 patients (97.9%). One hundred and eighty three of 185 patients were successfully treated with bowel rest and antibiotics. Two patients in stage Ⅰ b required a resection or surgical drainage because of inadequate response to conservative treatment. Current diverticulitis developed in 15 of 183 patients (8.2%) who responded to medical therapy. All 15 patients who suffered a second attack had uncomp licated diverticulitis, and were successfully treated with medical therapy. CONCLUSION: Our results indicate that right colonic diverticulitis is essentially benign and imageguided conservative treatment is required.
