Abstract

BACKGROUND: This study aimed to evaluate the diagnostic value of gray-scale and power Doppler sonography for acute cholecystitis and show a correlation between sonographic and intraoperative findings, quantitively.METHODS: Forty chronic and forty acute cholecystitis patients were examined. Early laparoscopic cholecystectomy was performed for acute cholecystitis. Demographic characteristics, sonographic findings, and adhesion scores were analyzed. Data were collected prospectively (clinicaltrials.gov: NCT02156947).RESULTS: Wall thickness (>=3 mm) and vascularity increased in acute cholecystitis (p<0.01 and <0.01). Vascularity was found to be moderately correlated with adhesion (p<0.01, r=0.59) but it did not affect the difficulty of the operation by means of perforation, conversion rate, and operation time. In addition, wall thickness did not correlate with adhesion formation (p=0.36). Sensitivity and specifity of wall thickness and vascularity were found to be 96.9%, 72.7%, and 68%, 87.2%, respectively. When both diagnostic measurements were taken into account, sensitivity was calculated 69.7% and specificity reached up to 97.6%.CONCLUSION: Vascularity correlated with adhesion but failed to predict operation difficulty. Specificity of gray-scale sonography could be improved with power Doppler examination; however, desired diagnostic accuracy could not be obtained with only quantitive measurements of sonography

Özet

AMAÇ: Akut kolesistit tanısında gri-skala ve power Doppler ultrasonografinin değerini belirlemek için kantitatif sonografik ve intraoperatif bulgular arasındaki ilişkiyi göstermek amaçlandı. GEREÇ VE YÖNTEM: Kırk kronik, 40 akut kolesistit hastası değerlendirildi. Akut kolesistit hastalarına erken laparoskopik kolesistektomi uygulandı. Demografik özellikler, sonografik bulgular ve adezyon skoru incelendi. Veriler ileriye yönelik olarak toplandı (clinicaltrials.gov: NCT02156947). BULGULAR: Duvar kalınlığı (>=3 mm) ve vaskülarite akut kolesistitte artmıştı (p<0.01 ve <0.01). Vaskülarite ile adezyon arasında orta düzey ilişki saptanmasına rağmen (p<0.01, r=0.59) perforasyon, konversiyon ve operasyon süresi açısından ilişki saptanmadı. Duvar kalınlığı adezyon gelişimi ile ilişkili değildi (p=0.36). Duvar kalınlığı ve vaskülarite için duyarlılık ve özgüllük sırasıyla: %96.9, %72.7 ve %68, %87.2 idi. Her iki tanısal değerlendirme birleştirildiğinde duyarlılık %69.7 iken, özgüllük %97.6'ya çıkmaktaydı. TARTIŞMA: Vaskülarite, adezyon gelişimi ile ilişkili, ancak operasyon zorluğunu belirlemede yetersiz idi. Gri-skala ultrasonografinin özgüllüğünün power Doppler inceleme ile artırılabileceği görüldü, ancak istenilen tanısal doğruluğa sadece kantitatif ultrasonografik bulgular ile ulaşılamayacağı anlaşıldı
