Table 2: Pre and postoperative data in the three studied groups (original table). As demonstrated in this table, the hospital stay in patients of group I (radical pericystectomy) ranged from 10-21 days and was statistically higher than the other groups (p value<0.001). Patients subjected to PAIR technique stayed at hospital for 1-2 days while patients who were managed by the modified technique stayed at hospital for 2-4 days. No biliary communication was recorded in all patients.
