The experimental study of liver cirrhosis with portal hypertension syndrome, modeled in 38 dogs, has been performed. Surgical treatment aimed on the portal decompression consisted of the implantation of the Celsite port-system. The reliable portal pressure decrease was observed in the first week of the experiment (from 269.3±17.8 to 157.4±26.5 millimeter of water). Portal decompression reasonably led to the improvement of the general state of the animals.

Biportal endoscopic spine surgery (BESS) is an emerging technique for lumbar spinal stenosis. Previous BESS techniques involve partial osteotomy for access to spinal canal such as partial laminotomy, partial facetectomy, and other forms to access the spinal canal for decompression. However, approaches that include osteotomy can cause bone bleeding intraoperatively, leading to obscured vision, and may be at risk of postoperative facet arthritis and segmental instability due to damage to the posterior stability structure.

- * MALIF was tested on 15 patients suffering from lumbar spondylolisthesis, resulting in a mean surgery time of about 97 minutes, minimal blood loss, and short hospital stays, with most patients experiencing symptomatic improvement.
- * The technique provides three main benefits: enhanced access to the surgery site, precise discectomy, and improved safety for the nerve root, indicating that MALIF could be a viable minimally invasive surgery option.

Introduction: With increasing life expectancy, degenerative lumbar spinal stenosis (LSS) has become a common problem in the geriatric population. LSS reduces the quality of life, limits daily activities, and requires therapeutic aids. We share our experiences of treating octogenarian patients with LSS with key lesion percutaneous single portal endoscopic unilateral laminotomy and bilateral decompression (sEndo-ULBD).

Left-sided portal hypertension (LPH) refers to increased splenic venous pressure caused by splenic vein stenosis or occlusion. Pancreatitis is the leading cause of LPH. Typically, LPH remains asymptomatic, but it can lead to life-threatening hemorrhage from ruptured fundal varices in about 10% of patients.
