Various haemodynamic changes are observed during laparoscopic surgery, relating to insufflation of CO2 & patient position. Cardiac output calculations using oesophageal doppler monitoring are based on the assumption that the aortic diameter is fixed. This study aims to measure the aortic diameter at preset times during surgery using ultrasound to discover if the diameter remains the same, and hence if the assumptions made by the oesophageal monitor are reliable. Assessing the aortic diameter involves a noninvasive ultrasound measurement taken in patients electively having laparoscopic procedures at the Royal Surrey County Hospital.
Purpose and design:This study aims to measure the aortic diameter at preset times during surgery using ultrasound to discover if the diameter remains the same, and hence if the assumptions made by the oesophageal monitor are reliable. Assessing the aortic diameter involves a noninvasive ultrasound measurement taken in patients electively having laparoscopic procedures at the Royal Surrey County Hospital.
Recruitment: Patients undergoing elective laparoscopic procedures at the Royal Surrey County Hospital. Recruitment done by Dr M Dickinson or Dr M Scott (COnsultant Anaesthetists). No therapeutic promises are to be made as this is purely an observational study.
Inclusion / exclusion: Patient refusal, Surgical refusal, Conversion to an open procedure.
Consent: Informed consent will be gained from each participant.
Risks, burdens and benefits: This is an observational study using a non invasive technique in patients undergoing elective surgery. There is very little in the way of risks, burdens and benefits to the patient.
Confidentiality: Caldicott principles will be adhered to.
Conflict of interest: None.
Use of tissue samples in future research: None.
Observational Model: Cohort, Time Perspective: Prospective

In many countries the gold standard for treating abdominal aortic aneurysms is still open surgery with a long incision. In patients with suitable anatomy alternatively an endovascular appr...
Screening for an abdominal aortic aneurysm, monitoring its growth and evaluation of its risk of rupture are based on the mesure of its maximum diameter. The abdominal aortic aneurysm's tre...
The primary outcome of this study was the evaluation of the efficacy of TAP block on pain intensity following open abdominal aortic surgery.
The objective of the study is to describe factors influencing abdominal compliance during laparoscopic surgery, including neuromuscular blocking agents (NMBA). The use of NMBA is randomize...
Abdominal aortic aneurysm (AAA) is a life threatening disease. There is a consensus to propose surgical repair in patients with a reasonable operative risk when the AAA exceeds 5 cm in dia...
Blunt abdominal aortic injury is an extremely rare condition. In the past, when blunt abdominal aortic injury was managed with open surgery, intra-abdominal injury was identified more easily, while in...
With increased experience and technological advancement, laparoscopic cholecystectomy is reported to be safe and feasible even in the presence of most of the previously recognized contraindications. T...
Endovascular Aneurysm Repair (EVAR) has become the standard of care for abdominal aortic aneurysm (AAA) but questions remain regarding benefit in high risk and elderly patients. The purpose of this st...
To evaluate reasons to deviate from aneurysm diameter thresholds, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation.
The relationship between preoperative hyperglycemia and postoperative acute kidney injury (AKI) occurrence in non-cardiac surgery including laparoscopic surgery remains unclear. This study aimed to as...
An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Methods to repair breaks in abdominal tissues caused by trauma or to close surgical incisions during abdominal surgery.
Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
