Sliding sign in third-trimester sonographic evaluation of intra-abdominal adhesions in women undergoing repeat Cesarean section: a novel technique.

OBJECTIVE: Intra-abdominal adhesions are associated with an increased risk of complications during repeat Cesarean section (CS), such as bladder and bowel injury, hemorrhage, infection and hysterectomy. We present a simple sonographic marker, the 'sliding sign' of the uterus, for the prediction of intra-abdominal adhesions in the third trimester of pregnancy in women undergoing repeat CS. METHODS: This was a prospective observational study of pregnant women with a history of at least one Cesarean delivery evaluated by transabdominal ultrasound during the third trimester of an ongoing pregnancy. In order to diagnose intra-abdominal adhesions, we assessed a sonographic sign, the sliding of the uterus under the inner part of the fascia of the abdominal muscles during deep breathing. Women were considered to be at high risk for severe adhesions if uterine sliding was absent and at low risk in the presence of obvious or moderate uterine sliding. A comparison between sonographic findings and intra-abdominal adhesions observed during surgery was performed. RESULTS: Of the 63 patients with one or more previous CS examined, 59 completed the study and underwent CS at our institution. In 16 of the 19 cases assigned to the high-risk group for severe adhesions due to absence of sliding of the uterus, the suspicion was confirmed at surgery. The prediction of low risk for adhesions was confirmed in 35 out of 40 patients. The sensitivity and specificity of the sliding sign in predicting presence of intra-abdominal adhesions in women undergoing repeat CS were 76.2% and 92.1%, respectively. Inter- and intraobserver correlation using Cohen's kappa coefficient were 0.52 and 0.77, respectively. CONCLUSION: Our data show that a simple sonographic sign might be able to discriminate between high and low risk for intra-abdominal adhesions in patients with a history of Cesarean delivery. This technique may aid clinical decisions in patients undergoing repeat CS. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

[Reliability of the diagnostic fluid mini-hysteroscopy in the diagnosis of intrauterine pathologies]. / Affidabilità della mini-isteroscopia diagnostica a liquido per la diagnosi delle patologie intrauterine.

AIM: The aim of this study was to determine the diagnostic accuracy of minihysteroscopy with fluid distention and vaginoscopic approach for the diagnosis of endometrial pathologies. METHODS: This controlled clinical study was conducted on 930 women with endometrial abnormalities who referred to our Department of Obstetrics and Gynecology, University Medical School of Bari, to perform hysterectomy. One week before hysterectomy all the patients underwent minihysteroscopy with fluid distention. Histological diagnoses were compared with the hysteroscopic findings, and the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were determined. RESULTS: Hysteroscopy was technically successful in all women and revealed sensitivity of 98%, specificity of 99%, a positive predictive value of 92%, a negative predictive value of 99%, and diagnostic accuracy of 99% for the diagnosis of endometrial carcinoma. CONCLUSIONS: Size reduction of the hysteroscope is of greatest importance for reducing pain and risk of vasovagal reaction. In conclusion, the best approach in terms of ease, reliability, acceptability, and safety to patients in whom intrauterine exploration is indicated should be simple diagnostic mini-hysteroscopy using a small-diameter, rod lens hysteroscope with a single-flow diagnostic sheath, vaginoscopic approach, and fluid distention. In this way in about 90% of patients, a correct diagnosis and proper choice for eventual subsequent operative strategy can be obtained, without discomfort and risk.
