A stereotactic device for rabbits based on mandibular and cranial landmarks
2008
✓ The authors have developed a stereotactic device for use in rabbits that uses the plane at the base of the mandible combined with cranial sutures as an anatomical reference. The device was developed for a study designed to evaluate catheters for infection prophylaxis, and this required the implantation of silicone catheters along a reproducible trajectory through the lateral ventricle. Cadaver and atlas studies demonstrated consistent spatial relationships between intracranial structures and the surface plane on which the animals were resting during the surgery. This plane is formed by the 2 mandibular angles and the mandibular tip. The authors developed a stainless steel stereotactic dev…
Biomechanical comparison between the modified rolling-hitch and the modified finger-trap suture techniques
2016
Purpose: The purpose of this study was to characterize the biomechanical effect of two grasping suture techniques used during ligament reconstruction: the modified rolling-hitch (MRH) and the modified finger-trap (MFT). Methods: Flexor profundus tendons were harvested from fresh pig hind-leg trotters. Each specimen was mounted on an electro-mechanic universal testing machine (Instron 3367). In half of all tendons (15 specimens), the suture was passed around the tendon following the MRH knot (Group 1). In the remaining half of all tendons (15 specimens), the suture was passed over a distance of 30 mm according to the MFT suture technique (Group 2). As per standard intra-operative technique, …
Renal transplantation by automatic anastomotic device in a porcine model
2015
Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…
Endoscopic transventricular third ventriculostomy through the lamina terminalis
2010
Object Endoscopic third ventriculostomy (ETV) has become a well-accepted option for obstructive hydrocephalus. However, standard ventriculostomy at the floor of the third ventricle might not be feasible under certain conditions. Here, the authors report in detail on their initial experience with an alternative option of endoscopic ventriculostomy through the lamina terminalis via a transventricular route. Methods Endoscopic third ventriculostomy through the lamina terminalis from a transventricular transforaminal route was evaluated in 4 cadaveric human heads and in 4 clinical cases. Results In all 4 human cadavers, an opening of the lamina terminalis via a transventricular approach could …
Eight-point compass rose underlay technique in 72 consecutive elderly patients with large incisional hernia
2011
Summary Background Repair of incisional hernia (IH) in the elderly is a challenge for the surgeon. Primary closure is preferable but is not always possible because of high recurrence rates of IH repaired without a prosthesis and/or possible respiratory and cardiovascular complications due to extreme tension of the margins. We report our experience with underlay mesh placement in elderly patients with large IH. Methods A total of 72 patients from January 2003 to December 2009 underwent IH repair involving placement of an intraperitoneal Gore® DualMesh® prosthesis. The prosthesis was first anchored at eight points in a compass rose pattern using a Gore® suture passer and then firmly secured t…
A Continuous Suture Anastomosis Outperforms a Simple Interrupted Suture Anastomosis in Esophageal Elongation.
2020
Abstract Introduction Long-gap esophageal atresia represents a distinct entity among the esophageal atresia spectrum. In many patients, achieving a reasonable anastomosis depends on some millimeters of tissue. We aimed to determine what effect the suturing technique would have on esophageal ex vivo elongation as it may determine the strength of a primary anastomosis. Materials and Methods In an analysis of porcine esophagi from animals for slaughter (100–120 days old with a weight of 100–120 kg), we determined esophageal length gain of simple continuous and simple interrupted suture anastomoses subjected to linear traction until linear breaking strength was reached. Statistical power of 80%…
Three single loops enhance the biomechanical behavior of the transtibial pull-out technique for posterior meniscal root repair
2017
Purpose: To investigate the effect of applying an additional suture to enhance the biomechanical behavior of the suture–meniscus construct used during the transtibial pull- out repair technique. Methods: A total of 20 fresh-frozen porcine tibiae with intact medial menisci were used. In one half of all speci- mens (N = 10), two non-absorbable sutures were passed directly over the meniscal root from the tibia side of the meniscus to the femoral side (2SS). In other ten specimens, three sutures were passed over the meniscal root (3SS). All specimens were subjected to cyclic loading followed by load-to-failure testing. Displacement of the construct was recorded at 100, 500, and 1000 cycles. Fur…
Ureteral injury during left colectomy for cancer: Laparoscopic management. A case report
2020
Abstract Introduction Iatrogenic ureteral lesions may occur after any abdominal and pelvic surgery. They are severe and can affect renal function and even vital prognosis. This study aimed to determine the clinical aspects and the therapeutic approaches of a lower third injury of the ureter during a laparoscopic left colectomy. Presentation of case An 81 year-old-man with left-sided colon cancer underwent laparoscopic left colectomy. During surgery there was a continuous full-thickness solution of the left ureter for which an end-to-end ureteral anastomosis was performed. In the postoperative period the patient underwent multiple urological and radiological interventional procedures due to …
