Active clinical trials for "Postoperative Complications"

This study will record patient electrocardiograms - as well as various other body signals (e.g., blood pressure, pulse wave, peripheral hemoglobin oxygen saturation) - as monitored routinely both during and immediately subsequent to surgical operations performed under general anesthesia. Through retrospective analysis of patients' heart rate variability (HRV), in concert with the other abovementioned parameters, the investigators seek to forward the development of novel mathematical models and tools for on-line detection of cardiovascular and autonomic dysfunction in the perioperative setting.

Observational feasibility study using Patient Reported Outcomes (PRO) to assess quality of life and 'return to normal life' up to 1 year following emergency laparotomy

The aim of this study was to determine the histopathological results of parotid tumors and postoperative complications after partial superficial or total parotidectomy with facial nerve dissection and superficial musculoaponeurotic system reconstruction.

Patients operated for hip fractures are older and have several conditions that have negative influences on the perioperative and postoperative prognosis. Hip fractures can also be painful, which is stressful for the physiology of the patient. Many old patients have received to little fluid intake. They often have diuretic therapy, which even worsens dehydration/hypovolemia. Some patients have to wait several days for surgery. Several studies have shown a high degree of complications and an increased mortality in this patient group. Early preoperative optimization can improve the outcome. The available methods for optimization of the patient are complicated and time consuming. The investigators wish with this study to try new approaches to find which patients still are dehydrated when they come to the operation ward. The aim is to measure the color and density of the urine as well as to register the the variability in the plethysmographic curve before spinal anaesthesia. These results will be compared to circulatory instability during and after surgery as well as to postoperative complications.

The objective of this retrospective study is to evaluate the postoperative clinical outcomes at discharge, 1 month and 12 months, associated with the use of Parietex™ ProGrip™ in Laparoscopic Transabdominal preperitoneal inguinal hernia repair. Results from this study will be used to support the short- and long-term clinical outcomes of Parietex™ ProGrip™ when used in inguinal hernia repair by laparoscopic approach. Single center study Population: All subjects have undergone Laparoscopic Transabdominal preperitoneal surgical treatment for inguinal hernia repair with Parietex™ ProGrip™ without additional fixation between September 2008 and March 2010 (inclusive) with at least 12 months of follow-up. The primary outcome: • Proportion of subjects who experience hernia recurrence (defect treated initially with Parietex™ ProGrip™) within 12 months post-surgery. Recurrence is defined as a clinically manifest bulge or a protrusion exacerbated by a Valsalva maneuver in the operated groin. The recurrence symptoms are assessed by phone based on the Symptoms Questionnaire and the recurrence diagnosis is confirmed during a physical examination by a physician and defined as a clinically manifest bulge or a protrusion exacerbated by a Valsalva maneuver in the operated groin. If subject has a surgical repair of the hernia within the 12 month postoperative period, it will be documented as evidence of hernia recurrence. The secondary outcome: Incidence of Groin Pain (pain score 0-10) and analgesic use at discharge, 1 month and 12 month postoperatively Incidence of postoperative complications including, wound infection (any infection of the incision), mesh infection (an infection of the mesh), bleeding, mesh migration, mesh erosion, fistula, small bowel obstruction, seroma, hematuria, hematoma, inflammation, chronic pains/ inguinodynia, infection, visceral adherence, allergic reactions to the components of the product at discharge, 1month and 12 month post-operatively Patient satisfaction Operative time Hospital length of stay

The rate of serious complications are relatively low in bariatric surgery today, but still 3-4 % will suffer from a serious complication. There are factors known before the surgery or during the operation that are likely to increase the risk for a serious complication. If the investigators are aware of these we can optimize the patients risk factors prior to the operation or at least increase the awareness of the increased risk in some patients given the presence of risk factors.

Curative treatment of upper gastrointestinal tract neoplasms is complex and associated with high morbidity and mortality. In general, the patients are already malnourished, and early postoperative enteral nutrition is recommended. However, there is no consensus concerning the best enteral access route in these cases.

Advanced ageing is accompanied by loss of reserve in multiple organ systems leading to increased risk of complications after surgery.Frailty is a functional syndrome involving reduced physiological reserve and 25-56% of all elderly surgical patients are reported to be frail .

<Development of synthetic medical data generation technology to predict postoperative complications> In order to develop a model for predicting the occurrence of complications after surgery, it is necessary to establish a cohort along with statistical indicators related to the occurrence of complications. This study aims to combine synthetic medical data based on actual clinical data and develop a predictive model based on synthetic medical data. This will allow researchers to conduct research only with synthetic data without dealing with actual medical data, allowing them to use and process data without legal constraints, and to create as much data as they want based on various preprocessed, standardized, and labeled raw data. Patients from three hospitals in Korea (Seoul National University Hospital, Seoul National University Bundang Hospital, Seoul Metropolitan City-Boramae Medical Center) were enrolled for the study. Medical data (both clinical and laboratory) from 410,000 patients who were conducted surgery between 2005 and 2020 were collected to evaluate the performance of the prediction model using AKI-based prediction model development and external verification. Based on the collected patient data, synthetic medical data were combined using the machine learning algorithm, and the anonymity and re-identification of the synthesized medical data were evaluated. Also, the development of AI-based prediction model using synthetic medical data and the actual medical data model were compared.

To describe changes in various diurnal patterns in vital values after surgery. These will be analyzed based on whether the patients have complications or no complications.
