To review current literature on the outcomes, techniques and trend of endoscopic-assisted breast surgery (EABS) in the management of breast cancer over a 20 years period Materials and Methods: Literature search was performed using PubMed/Medline database from 1st January 1998 to 31st December 2018 using the terms "endoscopy", "endoscopy-assisted", "breast cancer", "mastectomy" and "breast conserving surgery". Additional studies were also identified by reviewing references of relevant articles. Only case series and cohort studies were included in this review. Oncological and surgical outcome measures as well as detailed technical aspects were discussed. Results: EABS was comparable in terms of oncological, surgical as well as aesthetic outcomes if compared to conventional techniques. Patient selection and important adjuncts are essential to ensure successful and safe conduct of EABS. Conclusions: Standardization of techniques, practice guidelines and objective outcome assessments methods might pave the way for better conduct of EABS and place EABS as one of the standards of care for breast cancer care.
