Introduction. Postoperative ileus remains a significant clinical problem after abdominal surgeries, which hampers recovery and increases treatment costs. In urological practice, postoperative ileus is most common in patients after laparoscopic radical cystectomy, due to the high degree of intestinal trauma.
The aim of the study is to develop and verify an ultrasound method for early diagnosis of postoperative intestinal paresis.
Materials and methods. Forty patients were included in this prospective, single-center, observational study. All of them underwent laparoscopic cystectomy with ileoconduit formation under standard general anesthesia. The exclusion criteria included access conversion, intraoperative complications, regular use of prokinetics and opioids, diabetes mellitus with autonomic neuropathy, and inflammatory bowel diseases. Ultrasonography was performed using a BK Medical Flex Focus 800 device with a 7.5–12.5 MHz linear high-frequency sensor on an empty stomach. The quantitative assessment of ileal peristalsis was performed twice: initially, 24±2 hours before the planned surgery, and 24±2 hours after the intervention. The frequency and amplitude of circular contractions were recorded for one minute, and the peristalsis index was calculated. A 40% or more decrease in peristalsis were considered as sign of postoperative ileus.
Results. The ultrasonography allowed us to detect signs of postoperative intestinal paresis 24 hours after surgery, which is 48 hours earlier than the appearance of its clinical signs. The sensitivity of the method was 92%, and the specificity was 88%. The use of this method in the ERAS protocol allows for timely measures to be taken to restore intestinal peristalsis, and has resulted in a 2.3-day reduction in hospital stay.
Conclusion. Early diagnosis of postoperative ileus using the developed ultrasonography protocol allows to reveal the signs of intestinal peristalsis disorders 24–48 hours before the onset of clinical manifestations of intestinal paresis, allowing for timely initiation of treatment, which improve recovery and reduce the length of hospital stay.
