BACKGROUND AND AIM: Hip fractures are associated with a significant risk of morbidity and mortality in the elderly population. Current guidelines propose that these patients should be operated as early as possible. Preoperative cardiac investigations, especially echocardiography, have been considered to delay surgery with few changes in the patient management. The present study has been conducted to evaluate whether preoperative echocardiography improve or worsen the prognosis in such hip trauma surgery...

BACKGROUND: A lasagna plot is a graphical tool that can display multiple longitudinal outcomes. To our knowledge, lasagna plots have not been used in publications of surgical studies before. The objective of this study was to demonstrate the results of surgical randomized controlled trials (RCTs) with lasagna plots in order to assess whether this can lead to new observations of the data presented in the original studies. MATERIAL AND METHODS: Lasagna plots were created with R for an RCT comparing endovascular and open repair for patients with a ruptured abdominal aortic aneurysm (AJAX trial), an RCT comparing laparoscopy or open surgery combined with either fast track or standard care for patients with colon cancer (LAFA trial) and an RCT comparing preoperative biliary drainage and early surgery for patients with pancreatic cancer (DROP trial)...

Diabetes mellitus (DM) is characterized by alteration in carbohydrate metabolism, leading to hyperglycemia and increased perioperative morbidity and mortality. It evolves with diverse and progressive physiological changes, and the anesthetic management requires attention regarding this pathology interference in multiple organ systems and their respective complications. Patient's history, physical examination, and complementary exams are important in the preoperative management, particularly glycosylated hemoglobin (HbA1c), which has a strong predictive value for complications associated with diabetes...

INTRODUCTION: Pancreatoduodenectomy (PD) typically follows preoperative biliary drainage (PBD) despite PBD being potentially harmful. This study evaluated a pathway to avoid PBD within the framework of the UK's NHS. METHOD: A prospective observational study of jaundiced patients undergoing PD for periampullary cancer. A pathway to provide early surgery without PBD was introduced at the start of the study period. RESULTS: Over 12 months 61 and 32 patients underwent surgery with and without PBD respectively; 95% of patients in the PBD group had been stented before referral...

PURPOSE: Focal cortical dysplasia (FCD) is intrinsically epileptogenic, and an MRI-visible lesion typically constitutes the core part of the epileptogenic zone. We aimed to identify ictal EEG patterns that represent the epileptogenic zone by using subdural electrodes placed over the MRI-visible FCD lesion. METHODS: We selected seven patients with frontal lobe epilepsy caused by pathologically proven FCD type IIb who underwent preoperative intracranial EEG evaluation with subdural electrodes followed by resection surgery with seizure-free outcome...

INTRODUCTION: Total knee arthroplasty (TKA) is an operation with moderate to severe postoperative pain. The Fast-Track models employ local infiltration techniques with anaesthetics at high volumes (100-150ml). We proposed a genicular nerve block with low volume of local anaesthetic. The aim of our study is to evaluate the periarticular distribution of these blocks in a fresh cadaver model and to describe the technique in a preliminary group of patients submitted to TKA. MATERIALS AND METHODS: In the anatomical phase, 4 genicular nerves (superior medial, superior lateral, inferior medial and inferior lateral) were blocked with 4ml of local anaesthetic with iodinated contrast and methylene blue in each (16ml in total)...

Primary breast lymphoma (PBL) may mimic carcinoma clinically and also mammographic and ecographic distinction is subtle. Despite its rarity, incidence of PBLs has increased over the last four decades and continues to increase for younger women and for some subtypes, and for this reason it is increasingly important to achieve a preoperative pathological diagnosis using core needle biopsy (CNB) or fine-needle aspiration cytology (FNA). The aim of this retrospective study was to report our single-center experience in CNBs performed for histological diagnosis of PBL compared to FNA...

The admission of lung cancer patients to intensive care is related to postprocedural/postoperative care and medical complications due to cancer or its treatment, but is also related to acute organ failure not directly related to cancer.Despite careful preoperative risk management and the use of modern surgical and anaesthetic techniques, thoracic surgery remains associated with high morbidity, related to the extent of resection and specific comorbidities. Fast-tracking processes with timely recognition and treatment of complications favourably influence patient outcome...
