To evaluate the application of treatment planning system (TPS)-assisted large-aperture computed tomography (CT) simulator to percutaneous biopsy.

This retrospective study enrolled patients that underwent TPS-assisted large-aperture CT simulator-guided percutaneous biopsy from November 2018 to December 2019. Retrospective analyses of puncture accuracy were compared using paired

-test and a Wilcoxon rank sum test. SB415286 molecular weight The risk factors for puncture accuracy and complications were identified.

A total of 38 patients were included in this study. There were no significant differences between the planned and actual puncture depth and angle. Pulmonary puncture was significantly associated with the accuracy of the puncture angle. The diagnostic rate of malignancy was 76% (29 of 38), of which 20 of 25 patients were in the group initially diagnosed with unconfirmed lesions and nine of 13 patients were in the group of treated patients that needed additional pathological analyses. For patients that underwent a pulmonary biopsy, 12 had minor pneumothorax and three suffered needle track bleeding. No other complications were observed. Regression analyses indicated a significant correlation between puncture angle and the incidence of pneumothorax.

TPS-assisted large-aperture CT simulator may improve the percutaneous biopsy procedure by combining the advantages of radiotherapy specialties with computer targeting.

Pediatric lumbar disc herniation (LDH), although uncommon, causes significant pain, discomfort, and sometimes disability. We examined the efficacy of percutaneous endoscopic lumbar discectomy (PELD) for pediatric LDH and the degree of lumbar disc degeneration at 1 year after PELD.

We retrospectively reviewed the data of pediatric patients with LDH who underwent PELD from December 2007 to July 2018. The patients' symptoms, physical examination findings, clinical images, visual analog scale (VAS) scores, Oswestry Disability Index (ODI), and perioperative results (blood loss, length of hospital stay, and complications) were obtained from the medical records. Lumbar disc degeneration was graded using the modified Pfirrmann grading system at the 1-year postoperative magnetic resonance imaging (MRI) examination.

Six boys and four girls who underwent PELD were evaluated. The patients' mean age was 15.6 years (range, 13-17 years). The mean VAS score for low back pain, mean VAS score for lower limb pain, and mean ODI preoperatively and 1 year postoperatively were 6.2 and 0.3, 6.9 and 0.5, and 20 and 0.1, respectively. MRI showed significant disc degeneration after PELD.

Treating pediatric LDH with PELD is safe and effective. It relieves pain and reduces disability. However, lumbar disc degeneration still occurs.

We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm.

We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals.

We included 25 studies (1831 patients). LPL was associated with a significantly higher stone-free rate, lower rates of blood loss, complementary treatment, blood transfusion, and complications, and less reduction in hemoglobin level compared with PCNL. LPL and PCNL were similar in terms of duration of hospital stay, conversion rate, changes in glomerular filtration rate and creatinine level, and mean time of postoperative analgesia. However, LPL was associated with a longer operation time than PCNL.

LPL appears to be more effective and safer than PCNL in patients with large renal stones, by increasing the stone-free rate and reducing blood loss, complementary treatment, blood transfusion, and complications compared with PCNL. LPL may thus be a useful modality for treating patients with large renal stones.

Patients with thoracic trauma caused by gunshots face a high risk of death, and medical staff often encounter technical difficulties in resolving these cases. Most gunshot wounds result in an entrance and exit wound. In cases with no exit wound, missiles are seen in other areas with screening radiographs. The bullet may migrate depending on gravity, coughing, swallowing, blood flow, or local erosion.

We present the case of a teenager who was hospitalized in critical condition owing to a left hemithorax injury caused by an improvised explosive device. The patient underwent two surgeries an anterior left thoracotomy during which a hole in the myocardium was sutured, and after radiography, anterolateral right thoracotomy was performed, in which a deformed projectile was found at the level of the intermediate right pulmonary artery.

This case highlights the crucial importance of repeated imaging to assess the possibility of projectile migration within the cardiovascular system in similar cases of penetrating injury. Immediate surgery was necessary and very important for the survival of our patient, despite the difficulties presented by this complicated case.
