A clinical study comparing ultrasound-measured pyloric antrum cross-sectional area to computed tomography-measured gastric content volume to detect high-risk stomach in supine patients undergoing emergency abdominal surgery

AbstractThe main aim of this study was to assess whether the ultrasound examination and measurement of the pyloric antral cross-sectional area (antral-CSA) in the supine position could be useful to diagnose a full stomach using a computed tomography (CT) as a comparator in emergency patients. Immediately before general anesthesia induction in patients undergoing emergency abdominal surgery, antral-CSA was measured and the volume of the gastric contents was evaluated via ultrasound in the supine position. Gastric content volume was also calculated from a CT image taken prior to the operation. The primary outcome of this study was to determine the antral-CSA threshold of the “high-risk stomach” defined as the presence of solid/thick fluid and/or gastric content volume>  1.5 mL/kg. The secondary outcome was to evaluate the correlation between gastric content volume calculated by CT and antral-CSA. Thirty-nine patients provided consent and were included. Ten patients had gastric contents over 1.5 mL/kg, and 18 patients showed solid contents/thick fluids. The med ian [IQR] antral-CSA and gastric content volume were 3.82 [2.74–5.07] cm2 and 0.32 [0.09 –2.08] mL/kg, respectively. The antral-CSA cutoff value of “high-risk stomach” was 3.01 cm2. This value had a sensitivity of 85%, a negative predictive value of 53%, and AUC of the ROC of 0.670 (p  =  0.03). The Spearman rank-order correlation between...

(Aust N Z J Obstet Gynaecol. 2019;59:45–53) The most common emergency nonobstetric abdominal surgery performed in parturients is appendicectomy, which occurs in ∼0.3% of pregnancies. Establishing the diagnosis of appendicitis is more challenging in pregnant women as a result of the physiological changes of pregnancy and the many non-specific symptoms experienced during normal pregnancy. In addition, the use of ultrasound to make the diagnosis is less effective due to the presence of the gravid uterus and computed tomography scanning is sometimes avoided to prevent fetal radiation exposure. Appendiceal perforatio...

Abstract OBJECTIVE: To describe our experience with office removal of nonpalpable contraceptive implants at our referral center. METHODS: We performed a retrospective cohort study by reviewing the charts of patients referred to our family planning specialty center for nonpalpable or complex contraceptive implant removal from January 2015 through December 2018. We localized nonpalpable implants using high-frequency ultrasonography and skin mapping in radiology, followed by attempted removal in the office using local anesthesia and a modified vasectomy clamp. We abstracted information on demographics, implant l...

This study reports the findings from 9 sheep that received sensor implantations. Time taken from initial CT scans to the placement of a single sensor into an OPA tumour was 45 ± 5 min, with all implantations resulting in the successful delivery of sensors into tumours. Immediate post-implantation mild pneumothoraces occurred in 4 sheep, which was successfully managed in all cases. This is, to the best of our knowledge, the first description of the use of naturally-occurring OPA cases as a pre-clinical surgical model. Through the integration of techniques used in the treatment of human lung cancer patients, including...

Authors: Denault A, Canty D, Azzam M, Amir A, Gebhard CE Abstract Whole body ultrasound can be used to improve speed and accuracy of evaluation of an increasing number of organ systems in the critically ill. Cardiac and abdominal ultrasound can be used to identify the mechanisms and etiology of hemodynamic instability. In hypoxemia or hypercarbia, lung ultrasound can rapidly identify the etiology with accuracy that is equivalent to computed tomography. For encephalopathy, ocular ultrasound and transcranial Doppler can identify elevated intracranial pressure and midline shift. Renal and bladder ultrasound can identi...
