A survey on the thermal conditions experienced by a surgical team
2007
The complex environment of the operating theatre is shared by a group of people having highly different needs: on one side, there is a surgical team whose work may last many hours and, on the other, an anaesthetized patient often subject to liquid infusion. Up to now, little consideration has been given to the different needs of the surgical team who may be affected according to their positions with respect to the scialytic lamp and their particular task. Clothing influences the comfort of the surgical team to a considerable degree: in fact, in some surgery (orthopaedics, neurosurgery and so on), surgeons and assistants must wear paper overalls beneath non-breathable plastic overalls and p…
The Effect of Postoperative Complications After Minimally Invasive Esophagectomy on Long-term Survival: An International Multicenter Cohort Study
2021
Item does not contain fulltext BACKGROUND: Esophagectomy is a technically challenging procedure, associated with significant morbidity. The introduction of minimally invasive esophagectomy (MIE) has reduced postoperative morbidity. OBJECTIVE: Although the short-term effect on complications is increasingly being recognized, the impact on long-term survival remains unclear. This study aims to investigate the association between postoperative complications following MIE and long-term survival. METHODS: Data were collected from the EsoBenchmark Collaborative composed by 13 high-volume, expert centers routinely performing MIE. Patients operated between June 1, 2011 and May 31, 2016 were included…
Beyond Magnamosis: A Method to Test Sutureless Esophageal Anastomotic Devices in Living Swine by Creating an Esophageal Bypass Loop for Natural Oral …
2019
Abstract Introduction: Thoracoscopic esophageal atresia repair has become increasingly popular, but is still limited to a few expert centers and has some challenges and shortcomings. One of them ha...
Imaging of Ventriculoperitoneal Shunt Complications: Comparison of Whole Body Low-Dose Computed Tomography and Radiographic Shunt Series.
2016
OBJECTIVE To determine diagnostic value and radiation exposure of low-dose computed tomography (LD-CT) compared to radiographic shunt series (SS) for the detection of ventriculoperitoneal (VP) shunt complications. METHODS Fourteen VP shunts were implanted in 7 swine cadavers. Mechanical complications were induced in 50% of VP shunts. Low-dose CT (80 kVp, 10 mAs, Pitch = 1.5) and SS were acquired. Dose area product (DAP) and effective doses for SS and LD-CT were collected. Scoring of diagnostic confidence and blinded readings of SS and CT data were performed. RESULTS The sensitivity of LD-CT was high (0.97; 95% confidence interval, 0.91-1.00) with excellent interobserver agreement (κ = 0.88)…
OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum
2018
Introduction. The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. Methods. Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several speci…
Tensiomyographical responsiveness to peripheral fatigue in quadriceps femoris
2020
Background Fatigue influences athletic performance and can also increase the risk of injury in sports, and most of the methods to evaluate it require an additional voluntary effort. Tensiomyography (TMG), which uses electrical stimulation and a displacement sensor to evaluate muscle contraction properties of one or more muscle bellies, has emerged as a technique that can assess the presence of peripheral and central fatigue without requiring additional voluntary efforts. However, the evaluation of the TMG’s ability to detect fatigue is limited, both at the level of muscle bellies and statistical methods. Thus, the aim of the present study was twofold: (i) to examine and compare the tensiom…
Static Crow’s Feet Treated with Voltaic Arc Dermabrasion (Atmospheric Plasma): Post-Operative Pain Assessment by Thermal Infrared Imaging
2021
Background: In the literature, several strategies have been described for the treatment of unaesthetic marks on the face resulting from the aging processes. The atmospheric plasma procedure is a non-invasive, inexpensive technique proposed for the rejuvenation of facial tissues. The aim of this study was to evaluate the performance of voltaic arc dermabrasion (VAD) for the treatment of static crow’s feet of the periorbital area. Methods: The crow’s feet of 135 patients (127 female and 8 male) were treated using the VAD technique. The perioperative skin temperature measurement was assessed using an Infrared Temperature sensor. The pain was measured using the Visual Analogic Score (VAS) at 1 …
Ultrasound-guided spinal fracture repositioning
1998
The management of narrowing spinal fragments in the operative treatment of spinal fractures remains an open question, in particular when the procedure is performed by a posterior approach. This article describes the use of intraoperative ultrasonography during spinal surgery. From 1990 to 1997, 116 spinal fractures were treated operatively at our clinic. Stabilization of the spine was achieved with the AO fixateur interne and the AO USS, respectively (Synthes, D-79224, Umkirch, Germany). For 60 cases who had a fractured posterior vertebral surface dislocated into the spinal canal, we used intraoperative ultrasonography to monitor the repositioning of the narrowing fragments. The patients un…
Clinical characteristics and outcomes of thymoma-associated myasthenia gravis
2021
[Background and purpose] Prognosis of myasthenia gravis (MG) in patients with thymoma is not well established. Moreover, it is not clear whether thymoma recurrence or unresectable lesions entail a worse prognosis of MG.
Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment.
2016
Long-term outcomes are of special concern in children after urinary diversion. In a single institution study we evaluated retrospectively the long-term outcomes of urinary diversion in children, in whom the ileocecal segment had been used, in respect to complications of the efferent segment.The Mainz pouch was used in 107 children for continent urinary diversion. Indications were neurogenic bladder (53%, 57/107), exstrophy-epispadias complex (25%, 27/107), malignancy (13%, 14/107), and others (9%, 9/107). Continent cutaneous diversion was performed in 95 patients, and 12 patients received bladder augmentation/substitution with a continent cutaneous stoma. As efferent segment, we used the in…
