Objective To investigate the clinical effecl of trabeculectomy with scleral tunnel in the treatment of refractory glaucoma. Design Prospective, randomized and comparative clinical study. Participants 87 patients (98 eyes) with refractory glaucoma. Methods The patients were randomly assigned to receiving trabeculectomy with or without scleral tunnel. The tunnel group (50 eyes) underwent trabeculectomy with an additional deep scleral tunnel of 5.0mm?1.5mm beneath the superficial scleral flap. The control group (48 eyes) underwent conventional trabeculectomy. The average follow-up period was 6 to 12 months posloperatively. Main Outcome Measures Visual acuity, intraocular pressures (IOP), filtering blebs, operative and postoperative complications. Results (1) No significant differences in visual acuity were found between two groups. (2) The postoperative IOPs were significantly lower than the preoperative IOPs in both groups, while the IOPs on the 7th day after the surgery between the two groups were not different significantly. The average postoperative IOP at the 6th month in the tunnel group was 14.34?3.95 mmHg and 19.57?7.76 mmHg in the control group, which were different significantly (P

Objective:To investigate the efficacy of early versus delayed laparoscopic cholecystectomy (LC) in the treatment of acute calculous cholecystitis complicated by abnormal liver function. Methods:A total of 106 patients with acute calculous cholecystitis complicated by abnormal liver function who received LC in Nanjing Drum Tower Hospital, Nanjing University Medical School, China between February 2018 and February 2020 were included in this study. They were assigned to receive laparoscopic cholecystectomy either within 72 hours after disease onset (early group, n = 51) or 72 hours after disease onset (delayed group, n = 51). Perioperative indexes, complications, immune function and liver function were compared between the two groups. Results:Intraoperative blood loss in the early group was less than that in the delayed group [(63.11 ± 8.18) mL vs. (92.39 ± 7.23) mL, t = 19.558, P < 0.001]. Operative time, time to anal exhaust and length of hospital stay in the early group were (49.53 ± 6.33) minutes, (23.24 ± 4.65) hours and (6.38 ± 1.23) days in the early group were significantly shorter than those in the delayed group [(63.24 ± 5.42) minutes, (32.88 ± 5.78) hours, (8.34 ± 1.54) days, t = 12.004, 9.415, 7.204, all P < 0.001]. There was no significant difference in the rate of conversion to open cholecystectomy during LC between the two groups ( χ2 = 0.877, P > 0.05). There was no significant difference in the incidence of complications between early and delayed groups [11.76% (6/51) vs. 7.27% (4/55), χ2 = 0.625, P > 0.05]. On day 3 after surgery, the proportion of CD 3+ cells and the ratio of CD 4+/CD 8+ cells in the early group were (37.81 ± 4.29) % and (1.32 ± 0.29), respectively, which were significantly higher than those in the delayed group [(32.56 ± 5.26) %, 1.21 ± 0.23, t = 5.605, 6.379, both P < 0.001]. Total bilirubin, alanine aminotransferase and alkaline phosphatase levels in the early group were (21.05 ± 5.16) μmol/L, (71.58 ± 9.36) U/L and (175.73 ± 19.64) U/L, respectively, which were significantly lower than those in the delayed group [(27.81 ± 5.14) μmol/L, (82.54 ± 12.35) U/L, (214.62 ± 20.58) U/L, t = 6.921, 7.893, 9.865, all P < 0.001]. On day 5 after surgery, total bilirubin, alanine aminotransferase and alkaline phosphatase levels in the early group were (14.63 ± 4.58) μmol/L, (42.13 ± 8.24) U/L, (137.72 ± 17.62) U/L, respectively, which were significantly lower than those in the delayed group [(18.67 ± 6.45) μmol/L, (59.64 ± 11.29) U/L, (162.76 ± 18.39) U/L, t = 3.692, 8.265, 7.462, all P < 0.001]. Conclusion:Early LC for treatment of acute calculous cholecystitis complicated by abnormal liver function can effectively promote the recovery of liver function, mitigate immune injury, improve perioperative indicators, and dose not increase the incidence of complications.
