Study | Country | Year | No. of patients | Failure (%) | Outcome |
---|---|---|---|---|---|
McDonald et al. [26] | America | 1989 | 82 | 11 (13.4%) | Over 1 year: 7.1% (4 of 56 patients) Less than 1 year: 26.9% (7 of 26 patients) |
Lieberman et al. [27] | America | 1994 | 32 | 3 (9%) | No difference between the 6 weeks protocol and over one year protocol. |
Haddad et al. [27] | United Kingdom | 2000 | 50 | 4 (8%) | No increased rate of failure in most case of at least 3-weeks inter-period. |
Sabry et al. [29] | America | 2014 | 314 | 105 (33.4%) | Increased interstage interval was associated with a higher infection rate. Failure:105 cases (average 124 days) / Success: 209 cases (average 96 days) |
Ines et al. [30] | Austria | 2015 | 76 | 19 (30.3%) | The optimal timing for second-stage surgery was between 4 and 11 weeks. |
Arash et al. [15] | America | 2018 | 282 | 63 (22.3%) | Length of interstage duration was not a statistically significant predictor. Interstage over 26 weeks had higher failure rate. |
Tobias et al. [31] | Germany | 2019 | 38 | 1 (2.6%) | Short interval (average 18 days) had a similar outcome with long interval (average 63 days) |
This study | Taiwan | 2023 | 361 | 27 (7.5%) | The timing of highest successful rate for second-stage surgery was between 16 and 20weeks. Internal over 24weeks groups implied decreased successful rate. No statistical difference between each group. |
