Filter by:Today there are various surgical techniques for inguinal hernia. In this study, investigators want to compare the ''PIRS'' operating technique laparoscopy and modified "Marcy" operating technique with open inguinal access. Investigators would compare both groups to find out witch one does the lesser inflammatory stress response on the organism.
Pelvic fracture urethral injuries (PFUI) occur in up to 10% of pelvic fractures. It remains controversial whether initial urethral realignment after PFUI decreases rates of urethral obstruction and the need for subsequent urethral procedures. The retrospective record review should determine the utility of acute urethral realignment after PFUI.
To provide treatment guidelines for patients with long bone metastatic disease based on observational study and to propose an algorithm to guide orthopedic surgeons in decision-making for these patient.
Allogeneic blood products transfusions are often necessary to treat perioperative bleeding in patients undergoing complex scoliosis surgeries. A prospective, randomized trial is designed to evaluate if the infusion of fibrinogen concentrate may reduce allogeneic blood transfusion in patients undergoing scoliosis surgery. Eligible patients will be randomly assigned to treatment group (fibrinogen concentrate infusion) and control group (normal saline infusion), and functional fibrinogen will be measured to guide the infusion of fibrinogen concentrate. Perioperative blood loss, intraoperative blood loss, and the amount of perioperative allogeneic blood transfusion will be compared between the two groups to determine the effect of fibrinogen concentrate infusion.
Combined hepatocellular and mass-forming cholangiocarcinoma (cHCC-MFCCC) is a rare tumor. The aim of this study was the analysis of the outcome comparing such tumor with classic hepatocellular carcinoma (HCC) and mass-forming cholangiocarcinoma (MFCCC).
The main aim of this project is to assess whether intravenous methylene blue can help identify the ureters during open and laparoscopic (keyhole) surgery. The ureters are small tubes that link the kidney to the bladder and, if not properly identified during surgery, may be damaged. Methylene blue has been safely given to patients for many years and it is fluorescent. It is removed by the kidney and will therefore travel through the ureters. Methylene blue shines brightly (becomes fluorescent) when viewed under red light. This study aims to compare the ability of methylene blue with white light to identify the location of the ureters during colorectal surgery. Recruitment will include 50 patients undergoing colorectal surgery (25 for keyhole/laparoscopic, 25 for open procedures). Each patient will act as their own control. To detect the fluorescence, a special fluorescent laparoscope for keyhole surgery will be utilised, and a wide-field camera will be used for open surgery. The potential benefits of this procedure are to identify the ureters during surgery and therefore prevent inadvertent damage to them It is hoped that near infra-red light emitting from the ureters will be detected. This will allow the surgeon to determine the anatomy of the ureters during the operation and avoid inadvertent injury.

The performance of hepatectomy for liver tumors using the thoraco-abdominal approach (TAA) versus the abdominal approach (AA) is still debated. The aim of the study is the analysis of the perioperative outcome of patients operated with or without the TAA for liver tumors.
The number of opioid overdose deaths in the United States has quadrupled in 15 years, a dramatic manifestation of the current opioid abuse epidemic. This rise parallels a sharp increase in the amount of legal prescription opioids dispensed. The abundance of prescription opioids available is a primary pathway for opioid abuse and diversion. Adjusting post- cesarean delivery opioid prescribing practices to better match actual patient need has the potential to reduce unused opioids available for diversion, nonmedical use, and development of chronic dependence, as well as reduce wasted resources.
Laparoscopy and robotic techniques are widespread procedures for pelvic gynecologic, urologic and abdominal surgery often performed in Trendelenburg position, with the application of pneumoperitoneum by inflating carbon dioxide. The rise in abdominal pressure following pneumoperitoneum and the head down body position have been shown to impair the respiratory function during the procedure, mainly inducing atelectasis formation in the dependent lung regions, worsening stress and strain of the alveolar structure. The application of a ventilator strategy providing positive end-expiratory pressure (PEEP) has been shown to reduce the diaphragm cranial shift, increasing functional residual capacity and decreasing respiratory system elastance. Furthermore, the application of recruiting maneuver followed by the subsequent application of PEEP improved oxygenation. These results are in accordance with finding by Talmor et al, evaluating the effect of a mechanical ventilation guided by esophageal pressure in acute lung injury patients. However a comparison between an esophageal pressure piloted mechanical ventilation and a conventional low tidal ventilator strategy with adjunct of PEEP and recruitment maneuvers according to clinical judgment has never been investigated in patients undergoing robotic gynecologic, abdominal or urologic surgery. The investigators aim to compare the conventional ventilation strategy (i.e. with application of PEEP and recruitment manoeuvre) with a ventilation driven by transpulmonary pressure assessed through an esophageal catheter, in patients undergoing to robotic surgery, with respect to oxygenation, expressed in terms of arterial oxygen tension - inspired oxygen fraction ratio (PaO2/FiO2) (primary endpoint), intraoperative respiratory mechanics indexes, number of lung recruitment maneuvers, rate and type of perioperative complications until hospital discharge (additional endpoint).
The objective of this study is to look at critical events in the pediatric operating room in a retrospective and now prospective fashion to determine if there are any trends such as age, presence of URI, type of surgery, type of airway, level of hands on provider, or other predictive markers associated these events so that we may gain some insight into perhaps reducing the incidence of these events or simply be more attune to the increased risks in certain situations.
