Resolving the organ transplantation challenges by 3D bioprinting: A scoping review on case studies

In response to the organ shortage and enhance surgical precision, 3D bioprinting has now become an innovative approach and technology that furnish practical challenges in the conventional medicine. Given the importance, the review is performed to understand clinical benefits and usage of this technology by using case studies on the 3D organ bioprinting implemented on the human live patients that implies about the various techniques of 3D organ printing. The study follows the standardized preferred reporting items for systematic review and meta-analysis structured (PRISMA-S) approach for the extraction of the relevant study from the databases by using the specific keywords such as "3D bioprint" and "Case study." Only five pertinent case studies are selected which include pubic bone rebuilding, spinal defect repair, and liver transplantation in complex anatomical circumstances. It is noted from the studies that using 3D bioprint in complex cases reduced operative time by 30% and it enhanced anatomical visualization, surgical accuracy, and preoperative planning, but also emphasizes issues like expense, adaptability, and regulatory concerns, highlighting the necessity for further study and clinical use.
