Filter by:Bacterial ecology of pilonidal cysts Single centre retrospective exploratory study of medical data contained in the medical records of patients operated on in the centre between 01/08/2020 and 30/11/2020.
Background of the project: The surgical treatment of parapelvic cysts is currently less researched and there is no gold standard for surgery. Previously, in percutaneous nephrolithotomy, we found that fenestration and fenestration drainage in the simultaneous treatment of pararenal pelvis cysts under nephroscopic nephroscopic surgery has clear curative effect, less trauma, and quicker recovery. Objective: To clarify the safety, efficacy and long-term efficacy of percutaneous nephroscopy in the treatment of parapelvic cysts. Nature: Retrospective case cohort study. Basic research process: Retrospective collection of cases in our hospital who underwent percutaneous nephroscopy for the treatment of parapelvic cysts, and comparison of preoperative and postoperative cyst size changes and long-term efficacy.
Patients with large hepatic cysts (> 5cm) may develop symptoms. These can be captured with the polycystic liver disease questionnaire (PLD-Q). Treatment of large hepatic cysts consists of aspiration sclerotherapy or laparoscopic fenestration. The safety and efficacy of both procedures has been explored in two recent systematic reviews yet no evident conclusion regarding superiority of either procedure could be drawn. The main objective of the ATLAS trial is to compare laparoscopic fenestration and aspiration sclerotherapy in patients with large symptomatic hepatic cysts on patient-reported outcomes.
Multicenter trial on the effect of the GnRH analogue leuprorelin on the growth of total liver volume in pre-menopausal women with very severe polycystic liver disease who, despite available therapy, experience growth and are heading for liver transplantation.
Intraorbital epidermoid and dermoid cyst (DC) has been reported in the literature rarely. The current study evaluates clinicopathologic, radiologic, and management of intraorbital DC cases over ten years.
Choledochal cysts are congenital cystic dilatations of the intra and/or extrahepatic bile duct. They have been considered a rare entity of the child population. Globally, they account for 1% of all biliary pathology benign, with a clearly higher incidence in Asian countries (1/5,000 in China, 1/1,000 in Japan, compared to 1/100,000-150,000 in Western countries). However, the number of adults diagnosed in recent years has increased by up to 70% due to improvements in imaging tests. Currently, the common bile duct malformation is considered a premalignant entity: although the data are not very precise, it is estimated that between 2.6% and 26% of patients diagnosed choledochal cyst, will develop cholangiocarcinoma. In this sense, we must bear in mind that most of the published literature is of Asian origin, where the rate of cholangiocarcinoma is 0.1-71/100,000 compared to 0.1-1.8/100,000 in Europe or 0.6-1/100,000 in the USA. The most used classification to differentiate the types of cysts is that of Todani. Following this classification, we would find a higher rate of malignancy on types I and IV. The recommendations found in the literature refer to the need for surgical intervention for choledochal cysts due to their high rate of malignancy. These recommendations are based on studies conducted in a symptomatic Asian population. We do not usually find in therapeutic algorithms the inclusion of various factors that could be involved in the development of malignancy such as episodes of cholangitis, presence of anomaly in the pancreatobiliary junction, presence of lithiasis in cystic dilatation, etc. Some surveys carried out among the scientific population reflect a lack of consensus on its management: in the same clinical situation, different surgery units specialized in hepatobiliary-pancreatic pathology would act in the opposite way (specifically surgical versus conservative treatment). Bile duct resection is not without complications, both short-term and long-term. Therefore, the patient's symptoms, age or comorbidities can play an important role in decision-making in the treatment of this pathology. This nationwide multicenter retrospective observational study aims to determine the clinical situation of this rare pathology in a Western environment. A retrospective analysis of patients diagnosed with choledochal cyst in the period between 2000 and 2020 is proposed. Demographic variables, risk factors for cholangiocarcinoma, symptoms associated with the cyst and its characteristics, diagnostic method, type of treatment, complications will be analyzed. Malignancy, time, and follow-up method will also be discussed. This study will attempt to answer questions about the incidence of choledochal cysts in our environment, their association with cholangiocarcinoma, the associated morbidity and mortality, as well as the therapeutic and follow-up attitudes adopted in the face of this rare pathology.
Cystic enucleation is one of the most common conservative surgeries in gynecology; it is commonly performed by a minimally invasive approach such as laparoscopy. A high percentage of these surgeries (6-88 % of cases) are complicated by the cystic rupture with intra-abdominal spillage of its contents (spillage). This occurrence affects the surgical and prognostic outcome by lengthening the time of surgery, increasing the risk of postoperative infection or granulomatous peritonitis, of possible second manifestation of the pathology (example: endometriosis), and in the case of neoformation of a carcinomatous nature by leading to an increase in the stage of disease, exposing patients to a prognostic disadvantage and the need for adjuvant treatments also avoidable. In addition, the previous spillage may be associated with the adherent syndrome with repercussions on patients' morbidity and fertility. For these reasons, it is crucial to optimize the selection of patients who are candidates for cystic enucleation. The present study aims to evaluate a series of ultrasound, medical history, and surgical-preoperative parameters to develop a predictive score for the risk of spillage during laparoscopic surgery. Prospective Observational Study. The study aims to enroll 156 patients.
The study aims at creating a prediction model using machine learning algorithms that is capable of predicting malignant potential of ovarian cysts/masses based on patient characteristics, sonographic findings, and biochemical markers
Pancreatic cancer is the fifth leading cause of cancer mortality in Hong Kong and the seventh leading cause of cancer mortality worldwide. In 2020, approximately 496000 new cases of pancreatic cancers were diagnosed globally . Pancreatic cancer is a highly fatal cancer with a case-fatality rate of 94.0% globally. In Hong Kong, both the incidence and mortality of pancreatic cancer have increased over the past decade. Due to the deep-seated location of pancreas, it is difficult to diagnose pancreatic cancer at an early stage, which in turn leads to delays in cancer treatment and poorer survival. Despite advances in oncologic treatment, the 5-year survival rate of metastatic pancreatic cancer remains poor (~2.9%). As such, there has been growing interest to improve pancreatic cancer prevention and survival by: 1. reduction of modifiable risk factors (eg, cigarette smoking, obesity, diabetes), 2. screening for early detection of high-risk pre-malignant lesions in selected high-risks patients with strong family history of pancreatic cancer and/or certain germline mutations of pancreatic cancer susceptibility genes (eg, BRCA1, BRAC2, DNA mismatch repair genes in Lynch Syndrome, etc) by magnetic resonance imaging (MRI) or endoscopic ultrasound (EUS), and 3. surveillance of pre-malignant precursor lesions such as mucinous pancreatic cystic neoplasms (PCN) by imaging and/or EUS to identify high-risk neoplastic progression indicated for surgical resection.
