Active clinical trials for "Postoperative Complications"

Purpose: The purpose of this study is to create prediction models for when major complications occur after elective colectomy surgery. Justification: After surgery, patients can have multiple complications. Accurate risk prediction after surgery is important for determining an appropriate level of monitoring and facilitating patient recovery at home. Objectives: Investigators aim to develop and internally validate prediction models to predict time-to-complication for each individual major medical complications (pneumonia, myocardial infarction (MI) (i.e. heart attacks), cerebral vascular event (CVA) (i.e. stroke), venous thromboembolism (VTE) (i.e. clots), acute renal failure (ARF) (i.e. kidney failure), and sepsis (i.e. severe infections)) or adverse outcomes (mortality, readmission) within 30-days after elective colectomy. Data analysis: Investigators will be analyzing a data set provided by the National Surgical Quality Improvement Program (NSQIP). Descriptive statistics will be performed. Cox proportional hazard and machine learning models will be created for each complication and outcome outlined in "Objectives". The performances of the models will be assessed and compared to each other.

Current study aims to analyze the outcomes of j-pouch and side-to-end anastomosis in rectal cancer patients treated with laparoscopic hand-assisted low anterior resection

We hypothesise that pain at minilaparoscopy for gynecologic disease is reduced when transvaginal rather than transumbilical specimen extraction is accomplished. This would be due to the avoidance of a 10-mm port in the umbilicus. Visual analogue scale score of post-operative pain will be obtained and patients satisfaction will be asked at the 2-month postoperative visit.

Prolonged pre-operative fasting increases postoperative hospital stay and current evidence recommends carbohydrate (CHO) drinks 2 hours before surgery. Our hypothesis is that the addition of hydrolized protein to a CHO-based drink not only reduces the inflammatory response but also diminish hospitalization.

The purpose of this study is to evaluate whether goal directed fluid management using respiratory variations in the oxygen saturation by pulse oximetry (SpO2) waveform has potential to decrease postoperative complications and outcomes.

The aim of the present study is to compare the functional and clinical differences and advantages between a standard operating system and a newly developed even smaller system for pars plana vitrectomy. The present study may work out the possible advantages and disadvantages between the routinely used 20-gauge vitrectomy system and the newly developed 23-gauge device.

With the knowledge of currently transmitted omicron variant being less virulent, over 90 percent of the Chinese population is fully vaccinated, and the Chinese health workers have sufficient experience treating the illness. China 's epidemic prevention and control has entered a new stage to restore the normal functioning of society and basic medical services, On Dec, 7, China released a circular on further optimizing its COVID-19 response, announcing 10 new prevention and control measures.This has marked the watershed for sharply increased number of elective surgical patients diagnosed with COVID-19 during preoperativley, fully recovered or during recovery. Beijing faced a wave of omicron infection starting that would result in of a wide range of population infections. At which time there is limited evidence regarding the optimal timing of surgery following SARS-CoV-2 infection especially for omiron among Chinsese patients .This study intends to explore the relationship between the incidence of postoperative complications after elective surgery and COVID-19 infection in Peking Union Medical College Hospital, and provide data support for the policy formulation of elective surgical timing for patients after COVID-19 infection.

The goal of this study is to develop a novel surgical risk stratification tool designed to adults operated in Brazil. The main question it aims to answer is: •Is the Extended Care (Ex-Care) II model a good tool to assess the risk of death among patients operated in Brazilian hospitals within 30 days after surgery? Information of patients undergoing surgery in the participating hospitals over a period of 24 months will be analyzed to evaluate the relationship of some patients characteristics (called predictors) with the study outcome (probability of death). The sample will be divided in two groups. The first, called derivation sample, will be used for the development of the Ex-Care II model. The second, called validation sample, will evaluate the performance of this new model.

Despite modern approaches to the diagnosis and treatment of acute bowel obstruction (ABO), postoperative mortality ranges from 5 to 32%, and complications occur up 23% of cases. One of the formidable infectious and inflammatory complications of ABO is sepsis. The main component of the development of sepsis in ABO is bacterial translocation (BT). BT is the migration of intestinal bacteria or their products through the intestinal mucosa into the mesenteric lymph nodes and further into normally sterile tissues and organs. Today there are several methods for detecting BT: direct method - the detection of 16s rRNA (ribosomal ribonucleic acid) in mesenteric lymph nodes (MLN); indirect method - the detection of serum lipopolysaccharide-binding protein (LBP) and presepsin (Soluble CD14 subtype or sCD14-ST). The aim of this study is to determine the diagnostic and prognostic significance of bacterial translocation as a predictor of the complications development in patients with malignant and benign acute bowel obstruction by assessing the relationship of biomarkers in the systemic circulation (LBP, sCD14-ST) with the detection of microorganism genes (16s rRNA) in mesenteric lymph nodes.

The aim of the present study is to explore the most efficient surgical approach in total hip replacement in short and long term when concerning strength, functionality and postoperative complications. The objective is to register muscular strength, hip joint functionality/mobilisation and complications after total hip arthroplasty (THA) performed by two minimal invasive/incision surgeries (MIS) versus the traditionally lateral approach. The primary working hypothesis is that due to a minimal dissection and reduced trauma in the muscles, patients will tolerate early hospital discharge better after MIS than after traditional lateral surgery. Patients in the MIS group will also be more active and maintain muscular strength and hip joint functionality/mobilisation better than patients in the lateral group.
