RESULTS: 111 cases of caecal and ascending
colonic diverticulitis were identified (90.2% of cases, male to female ratio 2.26:1, average age 39.6 ± 14.4 years, surgery ratio 24.3%, mean
hospital stay 7.4 ± 4.3 days, recurrence rate 3.6%). Three cases of transverse
colonic diverticulitis and three cases of descending
colonic diverticulitis were found. Six cases of Sigmoid
diverticulitis (4.9% of cases, male to female ratio 1:1, average age 67.7 ± 4.5 years, surgery ratio 33.3%, mean
hospital stay 11.7 ± 5.5 days, recurrence rate 0%) were found. 13 patients underwent right-sided
colonic diverticulitis resection and repair, while zero patients underwent
colectomy. Abdominal drainage was performed in 15 patients with right-sided
colonic diverticulitis. There was no significant difference in the length of
hospital stay among the three treatments for right-sided
colonic diverticulitis (P = 0.05). There was no significant difference in the recurrence rate among the three treatments of right-sided
colonic diverticulitis (P = 0.358). While the recurrence rate of right-sided
colonic diverticulitis was only 3.5%, relapse usually occurred within the first year following treatment.
CONCLUSIONS: In our patients, right-sided
colonic diverticulitis is more common in young and middle-aged patients than in elderly patients and we see a higher incidence in males. Acute right-sided complex
diverticulitis is rare. While non-surgical treatment is preferred for acute right-sided uncomplicated
diverticulitis, no significant difference in outcome was observed between the three different treatments we compared. Resection and repair of
diverticulum or abdominal drainage can also be used to treat patients with acute uncomplicated
diverticulitis.
