This prospective study included 242 children with intussusception treated at a single tertiary center between January 2023 and December 2024. All children received standardized USGHR...

Serum calprotectin as a biomarker for postoperative complications in colorectal surgery: a pilot study defining normal postoperative dynamics

Postoperative infections are the common cause of morbidity and mortality in colorectal surgery. Calprotectin, an S100 protein, may be a potential marker. The aim was to define the postoperative course (PC) of calprotectin in serum (CIS), compared to white blood cell (WBC), C-reactive protein (CRP), lactate and procalcitonin (PCT). This prospective, single-center study measured...

Identification of prognostic indicators for early recurrence of gastric cancer following laparoscopic gastrectomy

Effect of preoperative mental health status on spine surgery outcomes: a systematic review

Recent data reveals an association between preoperative mental health and postoperative outcomes in spine surgery. Patients with poor mental health often experience less favorable recovery trajectories, though long-term quality of life improvements may still be achieved. Understanding this relationship is essential for optimizing surgical planning and patient care. Several...

Risk factors for early-onset hyperuricemia and gout following laparoscopic sleeve gastrectomy: a retrospective study

A total of 535 obese patients who underwent LSG at Tianjin Medical University General Hospital between January 2022 and December 2024 were retrospectively enrolled according to predefined inclusion and exclusion criteria.Baseline and 1-month...

Thoracoscopic management of recurrent tracheoesophageal fistula: a single-center outcome analysis

Although thoracoscopic treatment of congenital esophageal atresia is widely accepted among pediatric surgeons, its application in recurrent tracheoesophageal fistula (RTEF) remains rare because of its technical difficulty. This study retrospectively analyzed thoracoscopic RTEF repairs at a single center to evaluate the safety, feasibility, and outcomes of this approach, providing...

Construction and application of a risk prediction model for sputum viscosity in patients with laryngeal malignant tumors after operation

This study aimed to evaluate the impact of sputum viscosity on postoperative recovery among patients with laryngeal malignancies. Additionally, it sought to identify risk factors associated with postoperative sputum viscosity and to develop a risk prediction model for its occurrence. Convenience sampling was employed to enroll 130 laryngeal malignancy patients hospitalized at a...

Precision medicine exploration of postpartum rectus abdominis muscle separation: from basic research to clinical practice

Postpartum diastasis recti abdominis (PDRA), characterized by pathological separation of the rectus abdominis muscles, affects 30%-60% of women, with many cases persisting beyond 6 months postpartum and having significant impacts on musculoskeletal function and quality of life. This review synthesizes recent advancements across molecular pathogenesis, precision diagnostics, and...

Surgical apgar score and delayed neurocognitive recovery in elderly patients: a prospective cohort study

Delayed neurocognitive recovery (dNCR) is a prevalent postoperative complication in elderly patients. Currently, there is no effective treatment for it. Consequently, timely risk identification and prevention of it are crucial. The aim of our study is to provide a clinical tool for the prediction of dNCR by exploring the relationship between the surgical Apgar score (SAS) and...

Early experience with ambulatory laparoscopic cholecystectomy in a regional hospital with limited ambulatory infrastructure: a retrospective cohort study using propensity score matching

Data on outcomes of ambulatory surgery in Thailand remain limited. Laparoscopic cholecystectomy is the first procedure included in Thailand’s national policy for ambulatory surgery requiring more than local anesthesia or intravenous sedation. This study aimed to compare outcomes of ambulatory versus conventional inpatient laparoscopic cholecystectomy in a regional hospital...

Laparoscopic resection of cecal duplication cyst in a 28 years old male: a rare case report

Cecal duplication cysts are a rare congenital anomaly, particularly uncommon in adults. With no clear etiology behind it, duplication cysts typically appear before 2 years of age. Their presentation is diverse, often mimicking other right lower quadrant pathologies. We report a case of an adult cecal duplication cyst treated successfully with laparoscopic resection, highlighting...
