SELF-EXPANDABLE METAL STENT PLACEMENT FOR CLOSURE OF A LEAK AFTER TOTAL GASTRECTOMY FOR GASTRIC CANCER: REPORT ON THREE CASES AND REVIEW OF THE LITER…
2014
In the setting of the curative oncological surgery, the gastric surgery is exposed to complicated upper gastrointestinal leaks, and consequently the management of this problem has become more critically focused than was previously possible. We report here three cases of placement of a partially silicone-coated SEMS (Evolution Controlled Release Esophageal Stent System, Cook Medical, Winston-Salem, NC, USA) in patients who underwent total gastrectomy with Roux-en-Y end-to-side esophagojejunostomy for a gastric adenocarcinoma. The promising results of our report, despite the small number of patients, suggest that early stenting (through a partially silicone-coated SEMS) is a feasible alternat…
Expression Profile of Stress Proteins, Intermediate Filaments, and Adhesion Molecules in Experimentally Denervated and Reinnervated Rat Facial Muscle
1997
The immunohistochemical profiles of ubiquitin, heat shock protein 70, alpha-B-crystallin, desmin, vimentin, neural cell adhesion molecule (N-CAM), and tenascin in rat facial muscle were studied after permanent denervation by transection of the facial plexus on one side and compared with findings after immediate reinnervation by hypoglossal-facial nerve anastomosis subsequent to transection on the contralateral side. Levator labii muscle samples were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery. Normal levator labii muscle fibers showed physiological expression of desmin and alpha-B-crystallin. Denervated rat facial muscle displayed distinct up-regulation of ubiquiti…
Morphology of experimentally denervated and reinnervated rat facial muscle I. Histochemical and histological findings
1994
The morphological changes in rat facial muscles were evaluated after permanent denervation and were compared with findings after immediate reinnervation. Thirty rats underwent transection of the left and right facial nerves immediately followed by hypoglossal-facial nerve anastomosis on the right side (muscular reinnervation) and removal of 8-10 mm of the facial plexus on the left side (permanent muscular denervation). Levator labii muscle samples of both sides were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery and submitted to routine histological and enzyme histochemical staining procedures. In normal levator labii muscles a typical "chessboard" pattern was found, …
The use of texture analysis to study the time course of chromatolysis
1998
Image analysis of the textural feature entropy of the Nissl substance was used to monitor the time course of chromatolysis in regenerating hypoglossal motoneurons and degenerating facial motoneurons 4-112 days after hypoglossal-facial anastomosis in rats. Changes in the Nissl substance were detected that were not obvious on the basis of subjective judgement of the light-microscopical appearance of the neurons. Chromatolysis started 4 days post operation (dpo) and was not reversed at 112 dpo in both nuclei. The increase of chromatolysis was 14-28 dpo faster in the regenerating hypoglossal neurons than in degenerating facial neurons. Maximal chromatolysis was measured at 56-70 dpo in both nuc…
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…
ROBOTIC VERSUS LAPAROSCOPIC INTRACORPOREAL ANASTOMOSIS IN RIGHT COLON CANCER SURGERY: ANALYSIS OF PATIENTS’ OPERATIVE OUTCOMES AND OPERATORS’ CURRENT…
2022
Background. Whereas laparoscopy proved to have better operative outcomes than open surgery over the years, robotic surgery provided no clear advantages over laparoscopy despite its more advanced technical features. However, robotic technology might help to achieve some advantageous procedures which are generally regarded as challenging, such as performing an intracorporeal anastomosis during a right colectomy. The objectives of this research project were: 1) to compare the outcomes of laparoscopic and robotic surgery in the case of a right colectomy with intracorporeal anastomosis for colon cancer; 2) to find any factors influencing surgical decisions and outcomes. Methods. First, we conduc…
Association of mechanical bowel preparation with oral antibiotics and anastomotic leak following left sided colorectal resection: an international, m…
2018
INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…
Surgical management of benign tracheal stenosis.
2014
Abstract This chapter provides a step-by-step explanation of the indications, basic technique and pitfalls of tracheal surgery for cases of benign tracheal stenosis. Approach, trachea dissection and end-to-end anastomosis in tracheal surgery is described in detail. An algorithm for laryngotracheal technique selection according to different criteria (stenosis location, vocal cords status and tracheal mucosa and/or cartilaginous larynx involvement) is also depicted. Finally, a review of the most important reported series in tracheal surgery is presented.
VITOM® 3D in Arterio-Venous Fistulas: Single Centre Preliminary Surgical Experience
2021
Background: Arteriovenous fistula (AVF) is the vascular access of choice for hemodialysis patients. A correct microsurgical vascular anastomoses is essential to the optimal care of patients. Loupes can help surgeons perform such procedures, but often cause neck or back pain and fatigue. Aim: This study aimed to evaluate whether a video telescopic operating microscope (VITOM®; Karl Storz Endoscopy GmbH, Tuttlingen, Germany) could be used as a substitute for loupes to create microsurgical vascular anastomoses. Methods: We evaluated microsurgical anastomoses with VITOM® in 10 patients (6 male, 4 female) from January 2019 to December 2019. The created anastomoses were 7 side-to-side, 2 side-to-…
Segmental resection of distal ureter with termino-terminal ureteric anastomosis vs bladder cuff removal and ureteric re-implantation for upper tract …
2019
OBJECTIVES: To compare overall (OS), cancer-specific (CSS), recurrence free survival (RFS) and post-operative renal function among patients affected by upper tract urothelial carcinoma (UTUC) of the distal (lower lumbar and pelvic) ureter, electively treated with segmental resection and termino-terminal anastomosis (TT) vs bladder cuff removal and ureteral re-implantation (RR). PATIENTS AND METHODS: A multicentre retrospective study, including 84 patients diagnosed with UTUC of the distal ureter and treated with TT or RR, is presented. The primary endpoint was to compare TT and RR in terms of OS, CSS and RFS. As a secondary outcome we compared the post-operative creatinine values as an inde…
