Biliary stent insertion during endoscopic retrograde cholangiopancreatography is a therapeutic intervention to relieve obstruction and facilitate flow through the biliary tree. In rare circumstances, these stents can migrate and result in distal gastrointestinal perforation, which may necessitate endoscopic or surgical intervention. We report a case involving a 79-year-old female who presented with peritonitis due to sigmoid colon perforation following biliary stent migration.

- Surgical treatment of symptomatic adult flatfeet can be approached using three techniques: subtalar arthroereisis (SA), medializing calcaneal osteotomy (MDCO), and a combination of both (SA+MDCO).
- A study involving 32 patients showed significant improvements in radiological parameters and patient-reported outcomes (AOFAS and EFAS scores) for all surgical approaches after an average follow-up of six years.
- The combination of SA+MDCO yielded the best outcomes, particularly for patients with severe flatfoot deformities, while MDCO alone had lesser effectiveness.
Article Synopsis
- Juvenile osteochondritis dissecans is the most common knee osteochondral issue in kids aged 10 to 14, usually due to repeated stress injuries from sports.
- The condition involves a bone lesion in the knee, typically on the inner part of the femur, and is influenced by factors like genetics and vitamin D levels.
- Treatment varies: stable lesions can heal with rest and avoiding activities, while unstable ones may require surgery to repair the joint and prevent arthritis later on.
Background: In pediatric orthopedics, long bone lengthening procedures are routinely performed using manual, motorized or magnetically controlled implants. This study aims to prove expansion of a newly designed osmotic pump prior to long bone lengthening in living organisms and to rule out any complications related to in vivo conditions, such as congestion of the semipermeable membrane, local infection, or lack of water to drive the osmotic pump, as well as to compare in vivo and in vitro expansion data.
Methods: Osmotic pumps, which were designed to distract a plate osteosynthesis, were inserted in the dorsal paraspinal musculature of four piglets.
Spinal muscular atrophy (SMA) is a rare genetic disorder, with the most common form being 5q SMA. Survival of children with severe SMA is poor, yet major advances have been made in recent years in pharmaceutical treatment, such as gene-therapy, which has improved patient survival. Therefore, clinical problems, such as the development of spinal deformities in these genetically treated SMA children represent an unknown challenge in clinical work.
