Background Educational resourceson the internet are extensively used to obtainmedical information. YouTube is the most accessed video platform containing information to enhance the learning experience of medical professionals. This study systematically analyzed the educational value of microsurgery-related videos on this platform. Methods A systematic review was conducted on YouTube from April 18 to May 18, 2020, using the following terms: “microsurgery,” “microsurgical,” “microsurgical anastomosis,” “free flap,” and “free tissue transfer.” The search was limited to the first 100 videos, and two independent reviewers screened for eligible entries and analyzed their educational value using validated scales, including a modified version of the DISCERN score (M-DISCERN), Journal of the American Medical Association (JAMAS) benchmark criteria, and the Global Quality Score (GQS). Evaluation of video popularity was also assessed with the video power index (VPI). Results Of 356 retrieved videos, 75 (21%) were considered eligible. The educational quality of videos was highly variable, and the mean global scores for the M-DISCERN, JAMAS, and GQS for our sample were consistent with medium to low quality. Conclusions A limited number of videos on YouTube for microsurgical education have higheducational quality. The majority scored low on the utilized criteria. Peer-reviewed resources seem to be a more reliable resource. Although the potential of YouTube should not be disregarded, videos shouldbe carefully appraisedbeforebeing used as an educational resource.

Jair Diaz-Martinez,Oscar Chapa-Azuela,Jorge Alberto Roldan-Garcia,Gustavo Alain Flores-Rangel 한국간담췌외과학회 2020 Annals of hepato-biliary-pancreatic surgery Vol.24 No.2

Backgrounds/Aims: The bile duct injuries are the most severe complications that occur after the surgical manipulation of the bile duct. The hepaticojejunostomy remained as the best treatment. Several factors identified that affect the result. This study aimed to analyze and identify risk factors that affected the evolution of these patients. Methods: A retrospective, observational study was conducted from February 1998 to June 2017. We included all patients with bile duct injuries who required surgical treatment. Results: We found 79 patients. The majority had a Bismuth type III in 35.4% (n=28). The morbidity of the Hepaticojejunostomy was 19% (n=15). In short-term follow-up, the main complications were cholangitis 11.4% (n=9) and bile leak 10% (n=8). In the long-term follow-up, in 2.5% (n=2) stricture was presented. On the comparison between postoperative and preoperative parameters, biliary peritonitis after a cholecystectomy (p=0.02) was an independent predictor of postoperative morbidity (p<0.05). Conclusions: In the treatment of bile duct injuries, different factors affect their outcomes. Our results show that infectious complications continue to affect the results of the treatment of bile duct lesions.

Use of radiotherapy in patients with palliative double bypass for locally advanced pancreatic adenocarcinoma

Glinka, Juan,Diaz, Federico,Alva, Augusto,Mazza, Oscar,Claria, Rodrigo Sanchez,Ardiles, Victoria,Santibanes, Eduardo de,Pekolj, Juan,Santibanes, Martin de The Korean Society for Radiation Oncology 2018 Radiation Oncology Journal Vol.36 No.3

Purpose: Pancreatic cancer (PC) has not changed overall survival in recent years despite therapeutic efforts. Surgery with curative intent has shown the best long-term oncological results. However, 80%-85% of patients with these tumors are unresectable at the time of diagnosis. In those patients, first therapeutic attempts are minimally invasive or surgical procedures to alleviate symptoms. The addition of radiotherapy (RT) to standard chemotherapy, ergo chemoradiation, in patients with locally advanced pancreatic cancer (LAPC) is still controversial. The study aims to compare outcomes in patients with a double bypass surgery due to LAPC treated or not with RT. Materials and Methods: A retrospective cohort study of patients with double bypass for LAPC were registered and divided into two groups: treated or not with postoperative RT. Baseline characteristics, postoperative complications, those related to RT and their relation to the main event (mortality) were compared. Results: Seventy-four patients were included. Surgical complications between the groups did not offer significant differences. Complications related to RT were mostly mild, and 86% of patients completed the treatment. Overall survival at 1 and 2 years for patients in the exposed group was 64% and 35% vs. 50% and 28% in the non-exposed group, respectively (p = 0.11; power 72%; hazard ratio = 0.53; 95% confidence interval, 0.24-1.18). Conclusion: We observed a tendency for survival improvement in patients with postoperative RT. However, we've not had enough power to demonstrate this difference, possibly due to the small sample size. It is indispensable to develop randomized and prospective trials to guide more specific treatment lines in this patients.

Objectives: Osteoarthritis (OA) is the most prevalent and disabling joint disease in the world. Temporomandibular joint (TMJ) exercise is a widely used treatment and could be a beneficial and long-term tool for treating TMJ OA. The present study aims to evaluate the effects of therapeutic exercise in the conservative treatment of TMJ OA. Materials and Methods: A single-group experimental pre-post test was performed. We included patients who met the diagnostic criteria for TMJ OA. Outcome variables were pain intensity (visual analogue scale), functionality (Helkimo index), and structural changes (ultrasound). Follow-up peri-ods were at months 1, 3, and 6. The intervention included a home-based program with thermotherapy, manual therapy, and therapeutic exercise during the entire follow-up period. Results: We included 15 patients and 26 joints, all women with a median age of 57 years (range, 49-62 years). Median change in pain intensity on joint palpation, mouth opening, and at rest at the first month was 47.5 mm, 51 mm, and 60 mm, respectively, and 48 mm, 49.5 mm, and 42.5 mm, at six months (P=0.001). The Helkimo index showed significant improvement in medians from baseline severe dysfunction (17 points) to minimal dys-function at three and six months (2 points) (P=0.001). Ultrasound showed improved disc position. Conclusion: This study demonstrated significant improvements in pain, function, and joint disc position and represents a valuable tool for the long-term treatment of patients with TMJ OA.
