The Role of 3D-Printed Patient-Specific Instrumentation in Total Knee Arthroplasty: A Literature Review.

Total knee arthroplasty (TKA) is currently one of the most common orthopedic surgeries due to the ever-increasing average life expectancy. The constant need for effective and accurate techniques was contributed to the development of three-dimensional (3D) printing in that field, especially for patient-specific instrumentation (PSI) and custom-made implants fabrication. PSI may offer numerous benefits, such as resection accuracy, mechanical axis alignment, cost-effectiveness, and time economy. Nonetheless, the results of existing studies are controversial. For this purpose, a review article of the published articles was conducted to summarize the role of 3D-printed PSI in TKA.

Gangrenous Cystitis: A Rare Case Report.

Gangrenous cystitis is a rare condition of the urinary bladder with bladder wall ischemia as the main etiopathogenic factor and constitutes a surgical emergency. The risk factors for this condition include diabetes mellitus, prolonged labor, and topical chemotherapy, and the condition must be immediately treated because of its high mortality rate. This report describes a rare case of a patient with gangrenous cystitis who underwent radical surgical treatment; the incidence, etiology, diagnosis, management, and outcomes are also discussed.

Endovascular Retrieval of a Detached and Dislocated Venous Port Catheter in the Right Heart Chamber Using a Triple-Loop Snare Device.

The authors present a case of a successful percutaneous retrieval of a detached port-a-catheter device that had migrated to the right cardiac chambers in a patient with inoperable pancreatic cancer and hepatic metastases. The patient was admitted to the vascular clinic department on an urgent basis due to an accidental detachment of the catheter during removal at another hospital. The catheter had migrated from the initial placement site in the right subclavian vein to the superior vena cava and right heart chambers. Under local anesthesia, the right femoral vein was accessed using the Seldinger technique, and the migrated catheter was retrieved using a triple-snare-loop device for foreign body removal. Chest radiography after the retrieval procedure did not show any foreign bodies in the right heart chambers or superior vena cava. The patient was discharged home the following day.

Evisceration of a Small Bowel Segment Through a Drain Site: Lesson Learnt.

Evisceration is described as the removal of intra-abdominal organs outside the abdominal cavity after partial or complete dehiscence of an operative incision. Multiple organs have been reported in the literature as being eviscerated through a drain site. Zero point five per cent (0.5) to 1.2% of all cases include the small bowel. In most cases, evisceration occurs three to eight hours post-operation. This article reports a case of an eviscerated small bowel segment through a drain site, along with the drain six hours post-operative. To our knowledge, such a complication following open abdominal or laparoscopic surgery has not yet been reported. Due to the imminent risk of strangulation and subsequent necrosis of the eviscerated visceral organ, drain site evisceration requires immediate intervention.
