Objective: In urban medical centers, penetrating injuries of the chest, neck, and head are frequently encountered due to the use of firearms and sharp weapons. Successful management of esophageal injury requires a high index of suspicion and prompt diagnosis. The role of flexible endoscopy, a readily available modality, has not been studied extensively in the management of potential esophageal injuries due to trauma.
Methods: A retrospective chart review of 55 patients who underwent emergent flexible endoscopy for the evaluation of suspected penetrating esophageal injuries was performed to determine if endoscopy was safe and if it yielded information that altered patient management.
Results: Flexible endoscopy was performed safely in all patients. It yielded a sensitivity of 100%, specificity of 92.4%, a negative predictive value of 100%, and a positive predictive value of 33.3% for detecting an esophageal injury. Although positive findings (prevalence, 3.6%) are infrequent, no esophageal injuries were missed. Endoscopy altered patient management in 38 (69.1%) patients.
Conclusions: Emergent flexible endoscopic examination of the esophagus is a safe and useful diagnostic tool in the early evaluation of penetrating injuries. Flexible endoscopy resulted in four negative surgical explorations, which was deemed acceptable by the Trauma Service, as the consequences of a missed esophageal injury is likely to be devastating.

Since abdominal adhesion are quite problematic in abdominal and pelvic surgery, the conventional HA/CMC film are commonly used as an anti-adhesive material. However, such types are difficult to be rolled and delivered through the port of laparoscopic surgical devices due to adherence to the laparoscopic port or other parts of the films. To create an anti-adhesion film with more favorable handling properties and anti-adhesive effect, we developed a novel punctate uneven gelatin film (PU GF).

When a difficult airway is anticipated, awake tracheal intubation can be considered. Usually, low doses of sedatives are administered during this procedure for minimal sedation and anxiolysis, such as midazolam and remifentanil. The newly developed ultra-short-acting benzodiazepine remimazolam has a pharmacokinetic profile that is more suitable for titration during awake tracheal intubation than the long-acting midazolam.

Aim: To evaluate the efficacy of flexible ureteroscopic lithotripsy (FURL) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi based on decision tree model.
Methods: A total of 600 patients with ureteral calculi, including 289 treated with FURL and 311 cases with ESWL in Anqing Municipal Hospital from June 2021 to August 2023, were selected as study subjects. Perioperative indicators and stone clearance rate of the two groups were compared, and the preoperative and postoperative (24 and 72 hours) changes of serum creatinine, cystatin C (Cys-C) and microalbumin were observed.

Positive results from cancer screenings, like a cancer diagnosis, can increase the risk of cardiovascular disease (CVD) mortality due to heightened psychological stress. However, positive screening results may also serve as a teachable moment to encourage the adoption of a healthier lifestyle. Consequently, the overall association between positive screenings and CVD mortality risk remains unclear.
