Clinical and pathophysiological outcomes of the robotic-assisted Heller-Dor myotomy for achalasia: a single-center experience.

Laparoscopic Heller myotomy and Dor fundoplication is considered a safe and effective treatment for achalasia. Robotic-assisted Heller-Dor procedure (RAHD) has emerged as an alternative approach due to improved visualization and fine motor control. The aim of this prospective study was to evaluate clinical, and functional results of RAHD. We evaluated a group of 66 patients with achalasia that underwent robotic-assisted Heller-Dor operation. Before treatment all patients underwent a diagnostic work-up such as upper endoscopy, esophageal barium swallow and high resolution manometry. The presence of postoperative gastroesophageal reflux disease was diagnosed by impedance and pH monitoring (MII-pH). Dysphagia improved in 92.4% of patients after treatment. Barium swallow series showed esophageal emptying in 100% of patients and a significant reduction of the esophageal diameter (p = 0.00235). Forty-five of 66 patients (68.2%) underwent upper endoscopy and 35 of 66 (53%) underwent MII-pH. Esophageal erosions were found in 4/45 (8,8%) and MII-pH showed abnormal results in 3/35 patients (8.6%). RAHD ensures a meticulous esophageal and gastric myotomy, allowing to visualize and divide each muscle fibers with a low rate of intraoperative and postoperative complications. resulting in turn in good clinical outcomes, radiological findings and functional results even if robotic tecnique definitely increases the surgical cost in the treatment of these functional esophageal disorders.

[The prevention of postoperative deep venous thrombosis with heparan sulfate per os. A controlled clinical study vs. heparin calcium]. / Prevenzione della trombosi venosa profonda postoperatoria con eparansolfato per os. Studio clinico controllato vs eparina calcica.

The paper reports the results of a randomised study carried out on a pool of 100 patients undergoing surgery in order to assess the efficacy and tolerability of orally administered heparan sulfate versus heparin calcium in the prevention of postoperative deep-vein thrombosis. Despite the limits of oral administration, heparan sulfate is indicated in the pharmacological prevention of postoperative deep-vein thrombosis.

[Use of defibrotide in the treatment of acute superficial thrombophlebitis of the legs]. / Impiego del defibrotide nel trattamento delle tromboflebiti acute superficiali degli arti.

The efficacy of defibrotide in the treatment of acute thrombophlebitis of the legs has been investigated in 140 patients, randomized into two groups. All patients received defibrotide either alone or as an addition to conventional therapies. Two different schemes of administration were selected and carried out in each group, according to the time of onset of thrombophlebitis. Defibrotide demonstrated a good clinical efficacy in both groups, with a highly significant reduction in those patients receiving defibrotide and conventional therapies. The clinical result were outstanding in two subgroups: extensive thrombophlebitis and brachioaxillary phlebitis.
