AIM: Three-dimensional (3D) printing has been recognized as a revolutionary technological innovation that has benefitted numerous disciplines, including medicine. The present systematic review aimed to demonstrate the current applications of 3D printing in colorectal surgery along with the limitations and potential future applications of this innovation.
METHOD: A PRISMA-compliant systematic literature search of studies that applied 3D printing in colorectal surgery in the period from January 1990 to July 2018 was conducted. Electronic databases including PubMed/Medline, Scopus and the Cochrane Library were searched. All full-text original articles were eligible for inclusion.
RESULTS: Nine studies including 58 patients with a median age of 60.7 years were reviewed. The studies assessed 3D printing in patients with planned stoma construction, colon cancer with liver metastasis, right colon cancer, rectal cancer, intractable constipation and anal fistula. The applications of 3D printing were classified into three categories: patient education, preoperative planning and evaluation of response of colorectal liver metastasis to chemotherapy. 3D printed models aided in planning resection of colorectal liver metastasis, facilitating D3 lymphadenectomy in complete mesocolic excision, improving the understanding of pelvic anatomy in laparoscopic rectal cancer treatment, guiding electrode implantation in sacral neuromodulation for intractable constipation, and elucidating the morphology of anal fistula tract and anal sphincter muscles.
CONCLUSION: Colorectal surgery may benefit from 3D printing in enhancing patient education before stoma construction, preoperative planning and evaluation of the response of liver metastasis to chemotherapy using 3D ultrasonography.
