Background/aims: The progression of the inflammation to suppurative cholecystitis my depend on the number and size of gallstone. This is comparative study of correlation between the nature of gallstone (number and size) and progression of suppurative cholecystitis and effect to the difficulty in surgery.
Methods: We analyzed 1,235 patients who were treated with laparoscopic cholecystectomy for the gallstone disease including acalculus cholecystitis and acute suppurative cholecystitis with or without gallstones. One hundred and twenty nine patients were acute suppurative cholecystitis. The patients were grouped for arms according to the size of stones as follows; group Ⅰ has no stone, group Ⅱ＜ 1㎝, 1㎝〈group Ⅲ〈 2㎝ and group Ⅳ≥ 2㎝. Also the patients were grouped to for groups according to the number of stones; group A has no stone, 1≤group B≤3, 4≤group C≤6 and group D≥7.
Results: Conversion rate to open laparotomy was 17.1% (22/129). In case of suppurative cholecystitis, six patients were included in arm Ⅰ, 57 patients in arm Ⅱ, 35 patients in arm Ⅲ, nine patients in arm Ⅳ. And six patients were included in group A, 44 patients in group B, three patients in group C and 54 patients in group D of laparoscopic cholecystectomy. Of the 22 patients who were converted to open cholecystectomy, one patient was included in arm Ⅰ, 14 patients in arm Ⅱ, four patients in arm Ⅲ, three patients in arm Ⅳ. And one patient was included in group A, eight patients in group B, one patient in group C and 12 patients in group D of open conversion group. There was no statistical significance of the groups (p〉0.05). The mean size of stones of the patients with suppurative cholecystitis (129 patients) and simple cholecystitis patients (312) was 0.97 versus 0.91㎝ (p〉0.05). There was no statistical difference of th number and size of gallstones between simple and suppurative cholecystitis (p〉0.05).
Conclusion: The number and size of gallstone for the patients who were treated by cholecystectomy was not contributing factors to develope suppurative cholecystitis and conversion to open from laparoscopic cholecystectomy.
