Fifty Years of Innovation in Plastic Surgery
Kwasnicki, Richard M,Hughes-Hallett, Archie,Marcus, Hani J,Yang, Guang-Zhong,Darzi, Ara,Hettiaratchy, Shehan Korean Society of Plastic and Reconstructive Surge 2016 Archives of Plastic Surgery Vol.43 No.2
Background Innovation has molded the current landscape of plastic surgery. However, documentation of this process only exists scattered throughout the literature as individual articles. The few attempts made to profile innovation in plastic surgery have been narrative, and therefore qualitative and inherently biased. Through the implementation of a novel innovation metric, this work aims to identify and characterise the most prevalent innovations in plastic surgery over the last 50 years. Methods Patents and publications related to plastic surgery (1960 to 2010) were retrieved from patent and MEDLINE databases, respectively. The most active patent codes were identified and grouped into technology areas, which were subsequently plotted graphically against publication data. Expert-derived technologies outside of the top performing patents areas were additionally explored. Results Between 1960 and 2010, 4,651 patents and 43,118 publications related to plastic surgery were identified. The most active patent codes were grouped under reconstructive prostheses, implants, instruments, non-invasive techniques, and tissue engineering. Of these areas and other expert-derived technologies, those currently undergoing growth include surgical instruments, implants, non-invasive practices, transplantation and breast surgery. Innovations related to microvascular surgery, liposuction, tissue engineering, lasers and prostheses have all plateaued. Conclusions The application of a novel metric for evaluating innovation quantitatively outlines the natural history of technologies fundamental to the evolution of plastic surgery. Analysis of current innovation trends provides some insight into which technology domains are the most active.

Background/Aims: Colonoscopy is the gold standard diagnostic method for colorectal neoplasia, allowing detection and resection ofadenomatous polyps; however, significant proportions of adenomas are missed. Computer-aided detection (CADe) systems in endoscopyare currently available to help identify lesions. Diminutive (≤5 mm) and nonpedunculated polyps are most commonly missed. This meta-analysis aimed to assess whether CADe systems can improve the real-time detection of these commonly missed lesions. Methods: A comprehensive literature search was performed. Randomized controlled trials evaluating CADe systems categorized bymorphology and lesion size were included. The mean number of polyps and adenomas per patient was derived. Independent proportionsand their differences were calculated using DerSimonian and Laird random-effects modeling. Results: Seven studies, including 2,595 CADe-assisted colonoscopies and 2,622 conventional colonoscopies, were analyzed. CADe-assistedcolonoscopy demonstrated an 80% increase in the mean number of diminutive adenomas detected per patient compared withconventional colonoscopy (0.31 vs. 0.17; effect size, 0.13; 95% confidence interval [CI], 0.09−0.18); it also demonstrated a 91.7% increasein the mean number of nonpedunculated adenomas detected per patient (0.32 vs. 0.19; effect size, 0.05; 95% CI, 0.02−0.07). Conclusions: CADe-assisted endoscopy significantly improved the detection of most commonly missed adenomas. Although thismethod is a potentially exciting technology, limitations still apply to current data, prompting the need for further real-time studies.
