#1
Lorenzo Ball, Federico Costantino, Giulia Orefice, Karthikka Chandrapatham, Paolo Pelosi
Mechanical ventilation is a cornerstone of the intraoperative management of the surgical patient and is still mandatory in several surgical procedures. In the last decades, research focused on preventing postoperative pulmonary complications (PPCs), both improving risk stratification through the use of predictive scores and protecting the lung adopting so-called protective ventilation strategies. The aim of this review is to give an up-to-date overview of the currently suggested intraoperative ventilation strategies, along with their pathophysiologic rationale, with a focus on challenging conditions, such as obesity, one-lung ventilation and cardiopulmonary bypass...

BACKGROUND: Trabeculotomy with the Trabectome® is an effective surgical procedure to lower intraocular pressure (IOP). However, in some patients it does not lead to a significant IOP reduction despite a gonioscopically well visible opening of Schlemm's canal. This study investigated whether the size of the trabeculotomy opening and other parameters, including anterior chamber depth (ACD) are related to IOP reduction. METHODS: Retrospective observational case series with 93 eyes of 93 patients who underwent Trabectome surgery...

Implant treatment is safe and predictable with sufficient amount and quality of bone tissue. In case of severely reduced bone tissue after a tooth was lost, augmentation of such tissue is necessary before implant embedment. Retrospective evaluation covered 380 alveolar ridge reconstructions. The study material consisted of human grafts prepared by the Department of Transplantology and Central Tissue Bank, Medical University of Warsaw. Presentation of laboratory procedures in the context of physical parameters of frozen, radiation sterilised, allogeneic corticocancellous material was presented...

INTRODUCTION: Secondary cuff failure after shoulder replacement is disabling and often requires additional surgery. Increased critical shoulder angle (CSA) has been found in patients with cuff tear compared to normal subjects. The interobserver reliability of the CSA and the relationship between CSA and symptomatic secondary cuff failure after shoulder replacement were investigated. MATERIALS AND METHODS: Nineteen patients with symptomatic cuff failure after anatomic shoulder replacement (mean FU 45 months) were compared to a control group of 29 patients showing no signs of symptomatic cuff failure (mean FU 105...

BACKGROUND: Bilateral adrenalectomy is performed in cases with infantile-onset Cushing syndrome due to bilateral adrenal hyperplasia in McCune-Albright syndrome (MAS) because severe Cushing syndrome with heart failure and liver dysfunction can have a lethal outcome. This procedure can completely ameliorate hypercortisolism, although lifetime steroid replacement therapy and steps to prevent adrenal crisis are necessary. Recently, the efficacy of unilateral adrenalectomy has been reported in adult cases of bilateral macronodular adrenal hyperplasia, but there is no consensus regarding the appropriate surgical treatment for bilateral adrenal hyperplasia in MAS...

INTRODUCTION: Infected femoral pseudoaneurysms are a common presentation in intravenous drug users with little consensus as to the optimum management of these patients. Whilst emergency revascularisation options are available, excision and ligation of the femoral artery remains the most common operative intervention but risks leaving the patient with critical ischaemia or intermittent claudication. This case series reviewed the outcomes of 4 patients who underwent excision-ligation without revascularisation of an infected femoral pseudoaneurysm at a district general hospital...

The incidence of obesity is rising exponentially. This is having a direct impact on liver transplantation due to an increase in NAFLD disease and numbers of overweight and obese patients requiring transplantation. There is now evidence suggesting that obesity has a negative impact on both graft and patient survival. There remains an imbalance between number of donors available and patients requiring transplantation. We therefore need to ensure we make the best use of the organs available, optimizing graft and patient survival in those fortunate enough to receive an organ...

Discovering factors influencing the speed and accuracy of responses in tasks such as "Go/No-Go" is one of issues which have been raised in neurocognitive studies. Mathematical models are considered as tools to identify and to study decision making procedure from different aspects. In this paper, a mathematical model has been presented to show several factors can alter the output of decision making procedure before execution in a "Go/No-Go" task. The dynamic of this model has two stable fixed points, each of them corresponds to the "Press" and "Not-press" responses...

BACKGROUND: Identification of patients in whom adrenalectomy may be more difficult, can help in decision making in borderline and doubtful cases. The aim of the study was to determine patients criteria influencing difficulty of laparoscopic lateral transperitoneal adrenalectomy (LTA). MATERIAL AND METHODS: The study enrolled 275 patients who underwent LTA. We analyzed the impact of gender, age, history of previous abdominal surgery, body mass index, risk of anesthesia measured as ASA scale, size, localization (left/right), and histological type of the tumor on parameters reflecting the level of difficulty of the procedure: operative time, intraoperative blood loss, conversion rate and intraoperative complications rate...

Although soft tissue replacement has been clinically successful in many cases, the corresponding procedure has many limitations including the lack of resilience and mechanical integrity, significant donor-site morbidity, volume loss with time, and fibrous capsular contracture. These disadvantages can be alleviated by utilizing bio-absorbable scaffolds with high resilience and large strain, which are capable of stimulating natural tissue regeneration. Hence, the chemically crosslinked tridimensional scaffolds obtained by incorporating water-based polyurethane (PU) (which was synthesized from polytetramethylene ether glycol, isophorone diisocyanate, and 2,2-bis(hydroxymethyl) butyric acid) into a bioactive extracellular matrix consisting of small intestinal submucosa (SIS) have been tested in this study to develop a new approach for soft tissue engineering...

A tracheobronchial fistula (TBF) is a rare complication when an operation is performed to treat esophageal carcinoma; no consensus treatment strategy has emerged. We describe a surgical interposition strategy, using a new flap, to repair a TBF that arose when esophageal squamous cell carcinoma was treated with neoadjuvant chemoradiation and minimally invasive esophagectomy (the 3-stage McKeown procedure). We performed a skin perforator flap pedicled by the intercostal muscle. It is a valuable option that may be the optimal first-line treatment, especially in the context of neoadjuvant radiation therapy...

Spinal cord injury remains a major adverse event of extended thoracic and thoracoabdominal aortic surgical procedures. Preoperative identification of the Adamkiewicz artery and prompt reattachment of the targeted intercostal arteries during operation should contribute to preventing spinal cord injury. In this report, we describe a simple and definite identification of the critical intercostal artery during extended descending and thoracoabdominal aortic surgical procedures.

Ex vivo lung perfusion (EVLP) has been developed as a method to reassess and recondition marginal lungs. However, evaluation during procedures is limited to a combination of physiologic variables such as gas exchange, pulmonary mechanics, and pulmonary vascular resistance. The aim of this study was to analyze the feasibility of real-time computed tomographic (CT) imaging to improve the evaluation of the lung during EVLP procedures.

Surgical resection represents one of the essential cornerstones in multimodal treatment of malignant pleural mesothelioma. In cases of tumor infiltration of the lung, lung-scarifying procedures such as lobectomies or pneumonectomies might be necessary to achieve macroscopic complete resection. However, this increases the morbidity of the patients because it leads to possible delay of the planned chemotherapy or radiotherapy. Innovative surgical techniques are therefore required to enable salvage of the lung parenchyma and optimization of surgical treatment...
