Abstract Background Left renal vein (LRV) stenting is used in selected patients with symptomatic Nutcracker syndrome (NCS). Stent migration is uncommon but may be serious, particularly in interventions performed primarily for symptom relief. We report intracardiac migration after combined treatment of NCS-associated pelvic congestion syndrome (PCS) and use the event to discuss patient selection, …

Abstract Background Perioperative hemoglobin drop is widely used as a surrogate marker for blood loss and transfusion risk across surgical disciplines. However, its agreement with dilution-based estimates of hidden blood loss remains insufficiently validated. As both approaches represent indirect estimators rather than a reference standard, this study evaluates agreement rather than validation. M…

Abstract Background Superficial mass resection is a core surgical skill requiring practical training. Existing simulation models, such as silicone pads or virtual reality, are often costly or inaccessible, creating a need for an affordable and feasible alternative for surgical education. Methods In this feasibility study, we developed a low-cost, high-fidelity simulation model using a rind-on por…

Spontaneous renal rupture (Wunderlich syndrome) is a rare and life-threatening condition, typically occurring in kidneys with pre-existing ipsilateral pathology. The occurrence of spontaneous contralateral renal rupture with multisystem complications shortly after urological surgery is extremely uncommon. This case report describes the diagnosis and treatment of contralateral renal rupture follow…

With the global rise in nonagenarian and centenarian populations, demand for surgical and critical care in this age group is increasing. Acute biliary disease, particularly cholecystitis, often necessitates surgery, yet outcomes following cholecystectomy in the oldest-old ICU patients remain poorly characterized. This study aimed to identify clinical and biochemical predictors of mortality and re…

Developmental atlantal canal stenosis is a rare cause of high cervical myelopathy. When combined with multilevel subaxial cervical stenosis, even minor trauma may result in severe neurological deficits. Surgical management remains challenging, particularly when C1 is involved, as laminoplasty is conventionally limited to C3-C7. A 55-year-old male presented with acute cervical pain accompanied by …

Venous thromboembolism (VTE) prophylaxis with graduated compression stockings (GCS) is a standard of care in gynecologic oncology surgery; however, the mechanical risks in specific patient populations require critical attention. A 24-year-old morbidly obese patient (BMI 41.7 kg/m²) with ovarian carcinoma developed severe rhabdomyolysis and impending acute compartment syndrome (ACS) after a 7.5-ho…

Obesity in adults over 65 years is increasingly prevalent and linked to comorbidities like type 2 diabetes (T2D), hypertension (HTN), osteoarthritis (OA), and obstructive sleep apnea (OSA), where conservative treatments often fail. Laparoscopic sleeve gastrectomy (LSG) effectively treats severe obesity, but prospective comparisons with non-surgical management in this age group are limited. This p…

In laparoscopic inguinal hernia repair, synthetic meshes are widely used but carry risks such as chronic pain and a foreign body sensation. Biological meshes, as emerging materials, have not yet reached a consensus regarding their clinical effectiveness compared to synthetic meshes. A systematic search of English and Chinese databases was conducted for randomized controlled trials (RCTs) up to Ja…

This long-term analysis suggests that the initial shift toward more advanced disease among patients undergoing appendectomy was not sustained, with presentation patterns and outcomes tending toward pre-pandemic levels during later pandemic waves. These findings may reflect adaptive processes within the healthcare system, despite ongoing external stress.
