BACKGROUND Rapid and efficient processes are essential for medical device research and development. To address this need, we established an open innovation research and development platform involving clinicians, manufacturers, sales companies, and experts in intellectual property and regulatory, aiming to develop new medical devices for minimally invasive treatment. The purpose of this study is to retrospectively and internally evaluate the research and development activities and outcomes of this platform to identify factors contributing to successful development of medical devices. METHODS A retrospective analysis of our team was conducted, focusing on successful device development, device classification, development duration, targeted medical areas, intellectual property rights, and manufacturer involvement. The study also evaluated external funding, academic publications, and international market expansion. Data were extracted from our team's project database and analyzed using descriptive statistical methods. RESULTS The platform facilitated the development of 28 medical devices, achieving a successful device development rate of 50%. These devices primarily targeted endoscopy (48.2%) and laparoscopy (25%),with an average development of 36 months. The intellectual property acquisition rate was 50%, including patents (39.3%) and trademarks (44.6%). Collaboration with sales companies and manufacturers was high at 82.1% and 71.4%, respectively. External funding supported 44.6% of projects, and academic publications were associated with 32.1%. In addition, 12.5% of the projects achieved international market expansion. Key success factors included intellectual property acquisition (P < .001), external funding (P = .003), academic publications (P = .003), and involvement of sales companies in research and development (P = .03). CONCLUSION Our team has shown successful in research and development through collaborative efforts across academia, industry, and government. It highlights the importance of open innovation and interdisciplinary collaboration in addressing global health care challenges.

Robotic and laparoscopic gastrectomy for gastric cancer: comparative insights into perioperative performance and three-year survival outcomes. Gastric Cancer 2025; 28:514-526. [PMID: 40009253 DOI: 10.1007/s10120-025-01601-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2024] [Accepted: 02/16/2025] [Indexed: 02/27/2025]
Abstract
BACKGROUND The primary treatment for gastric cancer (GC) is surgical resection, particularly for locally advanced cases. While laparoscopic gastrectomy (LG) has shown short- and long-term benefits, robotic gastrectomy (RG) offers enhanced precision and may lead to better outcomes, especially in advanced-stage disease. METHODS This retrospective study analyzed data from 1538 patients with pathological Stage I-III GC who underwent RG or LG between 2014 and 2021. Propensity score matching created 466 matched pairs. Perioperative outcomes, 3 year overall survival (OS), 3 year recurrence-free survival (RFS), and recurrence patterns were compared between RG and LG. RESULTS RG demonstrated significantly shorter operative time (235.5 vs. 242.5 min, p = 0.001), less blood loss (19.1 vs. 33.4 ml, p < 0.001), and shorter hospital stay (7.9 vs. 9.7 days, p < 0.001). Overall complications did not differ significantly (p = 0.183), but RG had lower rates of anastomotic leakage (p = 0.045) and pancreatic fistula (p = 0.024). No significant differences in OS were observed in the overall cohort or by stage. Similarly, RFS showed no significant differences in the overall cohort (3 year RFS: RG 86.81% vs. LG 83.04%, p = 0.1347). By stage, no differences were found in stage I or II, but in stage III, RG showed better 3 year RFS (67.52% vs. 52.97%, p = 0.0424). RG also had lower recurrence rates (9.0% vs. 14.8%, p = 0.0061), with fewer liver (p = 0.0069) and lymph node metastases (p = 0.0223). CONCLUSION RG demonstrated superior short-term outcomes and comparable three-year OS to laparoscopic gastrectomy, with improved three-year RFS and reduced recurrence in Stage III, likely facilitated by earlier adjuvant chemotherapy initiation.

Abstract
Telemedicine has revolutionized the field of surgery, with telemonitoring and telesurgery being 2 of its most promising applications. Telesurgery and telemonitoring are revolutionary applications that have the potential to change the way surgical operations are performed. These applications can allow surgeons to perform operations, enable surgeons to perform operations by assisting or supervising others through mentoring from a different location (telementoring). Despite the potential benefits of telemedicine and telementoring, there are still challenges that must be overcome before they can be widely used in clinical practice. For example, latency in data transmission can be a problem in telemedicine, as even a small delay in data transmission can affect the accuracy of the operation. Additionally, a sophisticated and expensive technological infrastructure is required, which can limit their use in some clinical settings. Although we need to work on its development technologically, ethically and legally, it is a promising tool.

Abstract
BACKGROUND Fogging and staining of a laparoscope lens negatively impact surgical visualization. We hypothesized that the disposable hot pack could not only warm but also clean laparoscopes. Hence, this study verified and developed the disposable hot pack with anti-fogging and cleaning function. MATERIAL AND METHODS The laparoscope was inserted into a swine abdominal cavity for five minutes. Then, the laparoscopic tip was heated with 65 °C saline or the folded disposable hot pack with nonwoven fabric coated surfactant for ten seconds (n = 15). Also, a laparoscopic tip with dirt was wiped with the prototype or conventional gauze for 10 s (n = 10). The dirt, fogging, and temperature of the laparoscopic tip were respectively evaluated after the laparoscope was inserted into the abdominal cavity. RESULTS The laparoscopic tip temperature five minutes after insertion into the abdominal cavity was similar (31.1 °C vs 31.2 °C, p = 0.748) and there was no fogging in both methods. The conventional gauze had significantly less temperature of the laparoscopic tip after cleaning and higher fogging occurrence than the prototype (29.5 °C vs 34.0 °C, p < 0.001, 30% vs 0%, p = 0.030, respectively), although there was no dirt left after both methods. CONCLUSION The disposable hot pack has a strong potential as an anti-fogging and cleaning device for use during laparoscopic surgery.

Cloud platform to improve efficiency and coverage of asynchronous multidisciplinary team meetings for patients with digestive tract cancer. Front Oncol 2024; 13:1301781. [PMID: 38288106 PMCID: PMC10824572 DOI: 10.3389/fonc.2023.1301781] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 12/27/2023] [Indexed: 01/31/2024] Open
Abstract
Background Multidisciplinary team (MDT) meetings are the gold standard of cancer treatment. However, the limited participation of multiple medical experts and the low frequency of MDT meetings reduce the efficiency and coverage rate of MDTs. Herein, we retrospectively report the results of an asynchronous MDT based on a cloud platform (cMDT) to improve the efficiency and coverage rate of MDT meetings for digestive tract cancer. Methods The participants and cMDT processes associated with digestive tract cancer were discussed using a cloud platform. Software programming and cMDT test runs were subsequently conducted to further improve the software and processing. cMDT for digestive tract cancer was officially launched in June 2019. The doctor response duration, cMDT time, MDT coverage rate, National Comprehensive Cancer Network guidelines compliance rate for patients with stage III rectal cancer, and uniformity rate of medical experts' opinions were collected. Results The final cMDT software and processes used were determined. Among the 7462 digestive tract cancer patients, 3143 (control group) were diagnosed between March 2016 and February 2019, and 4319 (cMDT group) were diagnosed between June 2019 and May 2022. The average number of doctors participating in each cMDT was 3.26 ± 0.88. The average doctor response time was 27.21 ± 20.40 hours, and the average duration of cMDT was 7.68 ± 1.47 min. The coverage rates were 47.85% (1504/3143) and 79.99% (3455/4319) in the control and cMDT groups, respectively. The National Comprehensive Cancer Network guidelines compliance rates for stage III rectal cancer patients were 68.42% and 90.55% in the control and cMDT groups, respectively. The uniformity rate of medical experts' opinions was 89.75% (3101/3455), and 8.97% (310/3455) of patients needed online discussion through WeChat; only 1.28% (44/3455) of patients needed face-to-face discussion with the cMDT group members. Conclusion A cMDT can increase the coverage rate of MDTs and the compliance rate with National Comprehensive Cancer Network guidelines for stage III rectal cancer. The uniformity rate of the medical experts' opinions was high in the cMDT group, and it reduced contact between medical experts during the COVID-19 pandemic.

Abstract
BACKGROUND The aim of this study was to evaluate the influence of the institutional volume of abdominoperineal resections (APR) on the short-term outcomes and costs in the Brazilian Public Health system. METHODS This population-based study evaluated the number of APRs by institutions performed in the Brazilian Public Health system from January/2010 to July/2022. Data were extracted from a public domain from the Brazilian Public Health system. RESULTS Four hundred and twelve hospitals performed APRs and were included. Only 23 performed at least 5 APRs per year on average and were considered high-volume institutions. The linear regression model showed that the number of hospital admissions for APRs was negatively associated with in-hospital mortality (Coef. = - 0.001; p = 0.013) and length of stay in the intensive care unit (Coef. = - 0.006; p = 0.01). The number of hospital admissions was not significantly associated with personnel, hospital, and total costs. The in-hospital mortality in high-volume institutions was significantly lower than in low-volume institutions (2.5 vs. 5.9%; p: < 0.001). The mean length of stay in the intensive care unit was shorter in high-volume institutions (1.23 vs. 1.79 days; p = 0.021). In high-volume institutions, the personnel (R$ 952.23 [US$ 186.64] vs. R$ 11,129.04 [US$ 221.29]; p = 0.305), hospital (R$ 4078.39 [US$ 799.36] vs. R$ 4987.39 [US$ 977.53]; p = 0.111), and total costs (R$ 5030.63 [US$ 986.00] vs. R$ 6116.71 [US$ 1198.88]; p = 0.226) were lower. CONCLUSIONS Higher institutional APR volume is associated with lower in-hospital mortality and less demand for intensive care. The findings of this nationwide study may affect how Public Health manages APR care.

Abstract
Medicine in general is quickly transitioning to a digital presence. Orthopaedic surgery is also being impacted by the tenets of digital health but there are also direct efforts with trauma surgery. Sensors are the pen and paper of the next wave of data acquisition. Orthopaedic trauma can and will be part of this new wave of medicine. Early sensor products that are now coming to market, or are in early development, will directly change the way we think about surgical diagnosis and outcomes. Sensor development for biometrics is already here. Wellness devices, pressure, temperature, and other parameters are already being measured. Data acquisition and analysis is going to be a fruitful addition to our research armamentarium with the volume of information now available. A combination of broadband internet, micro electrical machine systems (MEMS), and new wireless communication standards is driving this new wave of medicine. The Internet of Things (IoT) [1] now has a subset which is the Internet of Medical Devices [2-5] permitting a much more in-depth dive into patient procedures and outcomes. IoT devices are now being used to enable remote health monitoring, in hospital treatment, and guide therapies. This article reviews current sensor technology that looks to impact trauma care.

BACKGROUND Optimal visualization and safety have always been essential in performing any type of endoscopic surgery. However, the safety of automatic gastrointestinal (GI) insufflation has yet to be thoroughly studied, especially when combined with manual insufflation. The current study aimed to verify whether the pressure limiter could lower GI endoluminal pressure during endoscopic procedures and affect the behavioral patterns of endoscopists. METHODS A preclinical blinded trial was conducted on endoscopists who had no knowledge regarding the presence of the pressure limiter that prevents a GI endoluminal pressure above 25 mmHg. Endoscopists in group A performed esophageal endoscopic submucosal dissection (ESD) with our insufflation device equipped with the pressure limiter, whereas those in group B performed the same procedure without the pressure limiter. During all procedures, endoluminal pressure was continuously monitored. The primary endpoint of the current study was to measure the endoluminal pressure with or without the pressure limiter during esophageal ESD, while the secondary endpoint was to evaluate the effect of the pressure limiter on intraesophageal pressure and perioperative outcomes during esophageal ESD. A questionnaire survey was conducted after each session. RESULTS A total of 79 endoscopists were included in this randomized control study. Group A had significantly lower endoluminal pressure than group B (10.6 ± 4.61 vs. 16.25 ± 7.51 mmHg, respectively; p < 0.05). Although two pigs in group B died from tension pneumothorax, none in group A died. Evaluation of lumen expansion, ease of aspiration, and visual field reproducibility were poorer in group A than in group B, although all fell within the acceptable range. Subjective evaluation of usability was divided into two categories, Excellent/Good and Poor/Bad, with no significant differences in any of the items. CONCLUSIONS This preclinical study showed that endoscopic treatment with an automatic insufflation system could be performed at lower endoluminal pressure with a pressure limiter, which had no adverse effects on the endoscopist's feels on endoscopic procedures with the device.

Abstract
(1) Background: In the last few years, technological developments in the surgical field have been rapid and are continuously evolving. One of the most revolutionizing breakthroughs was the introduction of the IoT concept within surgical practice. Our systematic review aims to summarize the most important studies evaluating the IoT concept within surgical practice, focusing on Telesurgery and surgical Telementoring. (2) Methods: We conducted a systematic review of the current literature, focusing on the Internet of Surgical Things in Telesurgery and Telementoring. Forty-eight (48) studies were included in this review. As secondary research questions, we also included brief overviews of the use of IoT in image-guided surgery, and patient Telemonitoring, by systematically analyzing fourteen (14) and nineteen (19) studies, respectively. (3) Results: Data from 219 patients and 757 healthcare professionals were quantitively analyzed. Study designs were primarily observational or based on model development. Palpable advantages from the IoT incorporation mainly include less surgical hours, accessibility to high quality treatment, and safer and more effective surgical education. Despite the described technological advances, and proposed benefits of the systems presented, there are still identifiable gaps in the literature that need to be further explored in a systematic manner. (4) Conclusions: The use of the IoT concept within the surgery domain is a widely incorporated but less investigated concept. Advantages have become palpable over the past decade, yet further research is warranted.

Abstract
Sudden spurting of Corona virus disease (COVID-19) has put the whole healthcare system on high alert. Internet of Medical Things (IoMT) has eased the situation to a great extent, also COVID-19 has motivated scientists to make new 'Smart' healthcare system focusing towards early diagnosis, prevention of spread, education and treatment and facilitate living in the new normal. This review aims to identify the role of IoMT applications in improving healthcare system and to analyze the status of research demonstrating effectiveness of IoMT benefits to the patient and healthcare system along with a brief insight into technologies supplementing IoMT and challenges faced in developing a smart healthcare system. An internet-based search in PUBMED, Google Scholar and IEEE Library for english language publications using relevant terms resulted in 987 articles. After screening title, abstract, and content related to IoMT in healthcare and excluding duplicate articles, 135 articles published in journal with impact factor ≥1 were eligible for inclusion. Also relevant articles from the references of the selected articles were considered. The habituation of IoMT and related technology has resolved several difficulties using remote monitoring, telemedicine, robotics, sensors etc. However mass adoption seems challenging due to factors like privacy and security of data, management of large amount of data, scalability and upgradation etc. Although ample knowledge has been compiled and exchanged, this structured systematic review will help the healthcare practitioners, policymakers/decision makers, scientists and researchers to gauge the applicability of IoMT in healthcare more efficiently.

Abstract
Telesurgery, or remote surgery, is widely known as a master-slave technology. It has achieved a milestone in surgical technology and intervention, providing widespread prospects of operating on a patient in a remote area with increased accuracy and precision. It consists of one or more arms controlled by a surgeon and a master controller in a remote area accessing all the information being transferred via a telecommunication system. This paper reviews the present advancements and their benefits and limitations in the field of telesurgery. A handful of operations have been done so far. However, due to time-lag (latency), global networking problems, legal issues and skepticism, and on top of the cost of robotic systems and their affordability have led to the concept of telerobotics and surgery to lag. However, with more information and high speed, 5G networking, which has been in a trial to reduce latency to its minimum, is beneficial. Haptic feedback technology in telesurgery and robotics is another achievement that can be improved; further, this allows the robotic arms to mimic the natural hand movements of the surgeon in the control center so that the master controller can perform surgeries with more dexterity and acuity. Due to coronavirus (COVID-19), this type of surgery approach can reduce the probability of contracting the virus, saving more lives and the future.

The endoluminal pressures during flexible gastrointestinal endoscopy. Sci Rep 2020; 10:18169. [PMID: 33097772 PMCID: PMC7584655 DOI: 10.1038/s41598-020-75075-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Accepted: 09/22/2020] [Indexed: 12/27/2022] Open
Abstract
In flexible gastrointestinal (GI) endoscopy, endoscopic insufflation is crucial and directly affects visualization. Optimal visualization enables endoscopists to conduct better examinations and administer optimal treatments. However, endoscopic insufflation is typically performed manually and is subjective. We aimed to measure the GI endoluminal pressure during flexible GI endoscopy. Participants underwent esophagogastroduodenoscopy (EGD) at our endoscopy center. Pressure measurement was conducted after completing diagnostic or follow-up EGD. The endoluminal pressure in the esophagus and stomach was measured at 1-s intervals for 1 min while performing EGD for observational and diagnostic purposes. During the measurements, the endoscopists maintained what they subjectively considered to be adequate exposure for screening for lesions by dilating the lumen. Eighty patients were enrolled in this study. The upper GI endoluminal pressure was assessed during EGD without adverse events. The esophageal endoluminal pressure averaged 8.9 (- 3.0 to 20.7) mmHg, and the gastric endoluminal pressure averaged 10.0 (3.0-17.9) mmHg; the upper GI endoluminal pressures were not affected by patient-related factors or the number of endoscopists' postgraduate years. We have successfully obtained the GI endoluminal pressures during EGD. Further accumulation of these data may lead to more stable and reproducible flexible endoscopic diagnosis and intervention.
