As @Alexander already mentioned, you are looking for an approach that is called "individual participant/person/patient data meta-analysis" (IPD meta-analysis). He also refered to an article by Richard Riley, who has published a lot in this field. Please find below a collection of articles that I used for our advanced meta-analysis class:

meta-analysis conducted with individual participant data versus
aggregated data. Psychological methods, 14(2), 165–176.

Best Answer
You can do this using the Generic Invariance Function in any of the major meta-analytic packages. Review Manager (RevMan is free from the Cochrane Collaboration) is a good example. You will need to input the effect estimate (e.g. Log Odds Ratio) and its Standard Error. If you are just given the OR and 95% confidence intervals then you need to back calculate the log of the OR, log of the Upper Confidence boundary (UCB), and log of the Lower Confidence Boundary (LCB). The Standard Error would be
(UCB - LCB)/(2 * 1.96).
Input that information into RevMan and you can then pool it.
Other statistical packages like Comprehensive Meta-Analysis can accept the OR and CIs without all the conversion, but they are not free.
Hope this helps.
