Advancements in Graft Placement Techniques.

For decades, the placement of follicular units (FUs) into incisions in the recipient area was exclusively carried out using forceps. In 1992, Dr. Choi introduced an instrument known as the "implanter," which had the advantage of simultaneously creating incisions and placing FUs without damaging sensitive parts.

Pancreatic islet allograft in spleen with immunosuppression with cyclosporine. Experimental model in dogs.

Purpose: To study the functional behavior of the allograft with immunosuppression of pancreatic islets in the spleen.

Methods: Five groups of 10 Mongrel dogs were used: Group A (control) underwent biochemical tests; Group B underwent total pancreatectomy; Group C underwent total pancreatectomy and pancreatic islet autotransplant in the spleen; Group D underwent pancreatic islet allograft in the spleen without immunosuppressive therapy; Group E underwent pancreatic islet allograft in the spleen and immunosuppression with cyclosporine. All of the animals with grafts received pancreatic islets prepared by the mechanical-enzymatic method - stationary collagenase digestion and purification with dextran discontinuous density gradient, implanted in the spleen.

Randomized clinical trial comparing spinal anesthesia with local anesthesia with sedation for loop colostomy closure.

Context: Recent studies have shown that local anesthesia for loop colostomy closure is as safe as spinal anesthesia for this procedure.

Objectives: Randomized clinical trial to compare the results from these two techniques.

Methods: Fifty patients were randomized for loop colostomy closure using spinal anesthesia (n = 25) and using local anesthesia (n = 25).

Esophagogastric anastomosis with invagination into stomach: New technique to reduce fistula formation.

Aim: To present a new technique of cervical esophagogastric anastomosis to reduce the frequency of fistula formation.

Methods: A group of 31 patients with thoracic and abdominal esophageal cancer underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube. In the region elected for anastomosis, a transverse myotomy of the esophagus was carried out around the entire circumference of the esophagus.
