Effectiveness of conservative approach in right colon diverticulitis.

BACKGROUND

Approximately 10%-25% of patients with colon diverticular disease experience colonic diverticulitis during their lives. Right-sided diverticulosis is a rare condition in Western countries, but it is common among Asian countries. The aim of this study was to evaluate the clinical and treatment outcomes in our patients with right colon diverticulitis.

METHODS

Demographic and clinical data of 22 patients with a diagnosis of cecum and right-sided colon diverticulitis between 2014 and 2017 were analyzed. The Hinchey staging was applied according to the radiological evaluation and clinical findings. Then, the proportions of demographic and clinical features of the patients according to the Hinchey staging and its statistical significance were evaluated.

RESULTS

Our study included 22 patients who suffered from right colon diverticulitis. The female-to-male ratio was 0.69. A total of 68.1% of the patients were the Hinchey Stage I, and 31.8% were the Hinchey Stage II, all of which were evaluated by tomography. The Hinchey Stage I diverticulitis was mostly found in the right colon (66.7%) and the Hinchey Stage II diverticulitis in the cecum (57.1%). The mean age of the Hinchey Stage II patients was higher (63.6 years) and statistically significant (p<0.05). Two patients had appendectomy, and one had right hemicolectomy. Conservative treatment was applied to other 19 patients. The mean hospitalization time was 3.4 days. Four patients who received conservative treatment at the 2-year follow-up had recurrence. No recurrence was observed in patients receiving surgical treatment.

CONCLUSION

Right colon diverticulitis is usually seen in solitary men aged <50 years from Eastern societies. As a treatment option, conservative methods should be preferred, especially in uncomplicated cases. Surgical treatment is usually used in the treatment of recurrent and complicated cases.
