The activity of riding artificial river waves, known as river surfing or rapid surfing, is growing in popularity, particularly among surfers from landlocked areas but also athletes new to the world of ocean surfing. The combination of wave conditions, board varieties, fin styles, and safety measures can, in some cases, cause overuse injuries.
Examining the occurrence, causal factors, and associated risks of river surfing injuries differentiated by wave types, and evaluating the practicality and appropriateness of safety gear in use.
Descriptive epidemiological studies focus on the presentation of disease data across different aspects of a population, such as demographics and geographic location.
Information regarding river surfers' demographics, injury history (past 12 months), surf site visits, safety equipment use, and health concerns was gathered through an online survey, disseminated via social media, in German-speaking countries. The survey was open to the public from November 2021 until February 2022.
The completed survey encompassed 213 participants, of which 195 hailed from Germany, 10 from Austria, 6 from Switzerland, and 2 from various other countries across the globe. Participants' average age was 36 years, distributed across a range of 11 to 73 years. 72% (n=153) were male, and 10% (n=22) were involved in competitive activities. learn more From the data, 60% (n=128) of surfers reported a total of 741 surfing-related injuries in the past 12 months. The bottom of the pool/river (35%, n=75), the board (30%, n=65), and the fins (27%, n=57) were the most commonly reported sources of injury. Contusions/bruises (n = 256), cuts/lacerations (n = 159), abrasions (n = 152), and overuse injuries (n = 58) surfaced as the most frequently encountered injury types in the study. The distribution of injuries showed a predominance in the feet/toes (n=90), head/face (n=67), hands/fingers (n=51), knees (n=49), lower back (n=49), and thighs (n=45). Fifty (24%) participants opted for earplugs, and a helmet was used habitually by 38 (18%) participants, while 175 (82%) participants never used a helmet.
River surfers commonly experience injuries such as contusions, cuts/lacerations, and abrasions. The pool/river bottom, the board, and the fins acted as the primary causative factors in the mechanisms of injury. learn more Injuries were more frequent in the feet and toes, then in the head and face, and finally in the hands and fingers.
River surfing often leads to injuries, specifically contusions, cuts, and abrasions, being the most frequent. The principal injury-inducing mechanisms were contact with the bottom of the pool or river, with the board, and with the fins. Injuries demonstrated a gradient, starting with the feet and toes, progressing to the head and face, and finally affecting the hands and fingers.
Owing to technical complications, including poor visualization and insufficient tension for the submucosal dissection plane, the endoscopic submucosal dissection (ESD) procedure displays a longer procedure time and a higher perforation rate in comparison to endoscopic mucosal resection. Various traction devices were designed to maintain the visual field's integrity and provide sufficient tension for the dissection. Evidence from two randomized controlled studies showed that the utilization of traction devices decreased the duration of colorectal endoscopic submucosal dissection (ESD) procedures, in relation to conventional ESD techniques, nevertheless, limitations, including the single-center nature of each trial, were present. The multicenter, randomized, controlled trial CONNECT-C marked the first time C-ESD and traction device-assisted ESD (T-ESD) were compared directly in patients with colorectal tumors. The operator, in the T-ESD, selected a traction method—either S-O clip, clip-with-line, or clip pulley—based on their judgment. C-ESD and T-ESD exhibited no statistically significant difference in the median time needed for the ESD procedure, which was the primary endpoint. When dealing with lesions that spanned 30 millimeters in diameter or when less experienced operators handled the procedure, the median time spent on ESD procedures leaned toward being shorter in T-ESD compared to C-ESD procedures. The CONNECT-C trial results, despite T-ESD's failure to minimize ESD procedure time, indicated its efficacy for addressing larger colorectal lesions and its suitability for use by less experienced surgeons. In contrast to esophageal and gastric ESD procedures, colorectal ESD faces difficulties stemming from limited endoscope maneuverability, which can contribute to a longer procedure time. The effectiveness of T-ESD in improving these issues remains questionable; however, the use of a balloon-assisted endoscope and underwater electrosurgical dissection might provide more successful resolutions, and integrating these methods with T-ESD may provide optimal treatment.
Several traction devices have been developed for endoscopic submucosal dissection (ESD), enabling a clear visual field and proper tension at the targeted dissection plane. Per-oral traction is facilitated by the clip-with-line (CWL), a time-tested traction device, pulling in the direction of the drawn line. A randomized controlled trial, conducted across multiple centers in Japan (the CONNECT-E trial), compared conventional endoscopic submucosal dissection (ESD) with combined cold-knife-assisted ESD (CWL-ESD) for large esophageal malignancies. The study found CWL-ESD associated with a shorter procedure time, defined as the time elapsed between the start of submucosal injection and the removal of the tumor, without increasing the chance of adverse events. A multivariate approach revealed that complete circumferential lesions within both the abdominal and esophageal regions were independent risk factors for technical complications, including operation durations exceeding 120 minutes, perforations, piecemeal resections, unintentional incisions (any accidental cuts made by the electrosurgical device within the marked region), or surgical handover to another operator. Subsequently, methods apart from CWL warrant examination for these lesions. The applications of endoscopic submucosal tunnel dissection (ESTD) for such lesions have been highlighted through thorough examinations and research. A randomized, controlled trial at five Chinese institutions compared the median procedure time for endoscopic submucosal tunneling dissection (ESTD) and conventional endoscopic submucosal dissection (ESD). The findings indicated a notable decrease in median procedure time for ESTD when treating lesions extending across half of the esophageal circumference. A propensity score matching analysis, performed at a single Chinese institution, demonstrated that ESTD, contrasted with conventional ESD, resulted in a shorter average resection time for lesions located at the esophagogastric junction. learn more Esophageal ESD procedures can be conducted with greater efficacy and safety through the strategic application of CWL-ESD and ESTD. Ultimately, the integration of these two approaches could prove to be effective.
Uncommon pancreatic lesions, solid pseudopapillary neoplasms (SPNs), present with a degree of malignancy that is not always predictable. EUS assessment is crucial for determining the nature of a lesion and confirming its tissue type. However, there is a dearth of data on the imaging evaluation of these growths.
To determine the distinctive endoscopic ultrasound (EUS) features of splenic parenchymal nodularity (SPN) and clarify its significance in the context of preoperative assessment is the intent of this investigation.
This international, multi-center observational study, performed retrospectively, involved prospective cohorts from seven large hepatopancreaticobiliary centers. Cases with SPN identified in their postoperative histology were all included in the research. The data included observations of clinical, biochemical, histological, and endoscopic ultrasound (EUS) features.
One hundred and six patients, who were diagnosed with the condition SPN, were involved in this study. A mean age of 26 years was observed, with a spread from 9 to 70 years, and a significant female majority (896%). Abdominal pain was the most prevailing clinical presentation, occurring in 80 instances (75.5%) out of the total 106 cases. Lesions presented an average diameter of 537 mm, with a range from 15 to 130 mm and a notable preponderance in the pancreatic head (44/106 instances; 41.5% occurrence). The predominant imaging characteristic of the lesions was solid (59 of 106 cases, or 55.7%). A noteworthy 33% (35 of 106) displayed mixed solid and cystic appearances, and 11.3% (12 of 106) exhibited purely cystic morphology.
