Abdominal Neoplasm

KeyScope and KeyLoop (collectively called KeySuite) are laparoscopic prototypes that the investigators have designed for the resources, needs and challenges of low- and middle- income countries (LMICs). KeyScope is a laparoscope that plugs into a laptop computer to display images during surgery. It links to a telementoring application so that experienced surgeons can mentor surgeons in capacity-building partnerships. KeyLoop is a laparoscopic retractor that lifts the abdominal wall during surgery, obviating the need for a constant power supply and medical-grade carbon dioxide. The investigators will perform a clinical First-in-Human study at the Uganda Cancer Institute. Ugandan surgeons will use the KeySuite devices to perform biopsies of intra-abdominal tumors.

This is a prospective two-center observational cohort study in adult patients undergoing major abdominal and/or pelvic oncologic surgery with pre-existing malnutrition. The study describes the course of postoperative gastrointestinal dysfunction and evaluates whether real-world exposure to parenteral serotonin as part of routine postoperative care is associated with a higher proportion of patients whose gastrointestinal dysfunction regresses to LIFE score less than or equal to 1 by postoperative day 5 (plus or minus 1 day), compared with patients not exposed to serotonin. All treatment decisions, including the use of parenteral serotonin, metoclopramide, neostigmine, nutritional support, and other postoperative management, are made solely by the treating physicians in accordance with routine clinical practice. The protocol does not assign, randomize, require, or restrict any drug treatment; it records real-world care, daily LIFE assessments during postoperative days 1 through 7, nutritional status measures, body composition where available, delirium screening, complications, length of stay, and mortality.

The goal of this clinical trial is to evaluate the application of intravenous contrast-enhanced ultrasound examination in children with intra-abdominal diseases that require clear diagnoses. The main questions it aims to answer are: * Is intravenous contrast-enhanced ultrasound helpful for the diagnosis of intra-abdominal diseases in children? * What medical problems do participants have when participating in intravenous contrast-enhanced ultrasound examination? * How can ultrasound doctors conduct intravenous contrast-enhanced ultrasound examinations in a standardized manner? Researchers will performing intravenous contrast-enhanced ultrasound examinations on participants and collecting research subjects to establish a multicenter clinical data database. Participants will: * Perform abdominal ultrasound examination to assess the condition. * At least conduct one intravenous contrast-enhanced ultrasound examination. Based on the result of the contrast examination, decide whether to conduct another examination. * Keep a diary of their symptoms and therapeutic process in 30 days.

This is an open label, multicenter, phase 1/2 study to assess the safety/tolerability and preliminary clinical activity of STAR0602 as a single agent administered intravenously in participants with advanced solid tumors that are antigen-rich.

Abdominal noncontrast scan and contrast-enhanced CT were used to establish a screening and diagnostic model for abdominal tumors

Evaluate LINFU® in patients who exhibit signs or symptoms (i.e. jaundice, abdominal pain, weight loss, nausea and vomiting etc.) suggestive of pancreatic cancer (PDAC) or have evidence of imaging studies suggestive of PDAC.
