Abstract

Abstract

Ascaris lumbricoides is the most common intestinal parasite to infect humans. The incidence of ascariasis is increasing in all part of the world because of world travel and population migration. Ascaris lumbricoides may cause various complications in the gastrointestinal system. Abdominal pain and tenderness with weight loss are the most common clinical presentations. The parasite can cause invagination at the intestinal segments and can enter the bile duct and cause cholangitis or biliary colic. Numerous studies have been published on biliary tract ascariasis. All these have documented ultrasonography (US) as the primary imaging modality for biliary ascariasis. In this report, we present US appearances in two surgical proven cases of gallbladder ascariasis.

Key words: Ascariasis, biliary tract, gallbladder, ultrasonography

Özet

Ascaris lumbricoides, insanları enfekte eden en sık intestinal parazittir. Askariazisin görülme sıklığı, göçler ve seyahatlere bağlı olarak dünya genelinde artmaktadır. Ascaris lumbricoides, gastrointestinal sistemde değişik komplikasyonlara neden olabilir. Kilo kaybı ile birlikte abdominal ağrı ve hassasiyet, en sık klinik başvuru yakınmalarıdır. Parazit barsak segmentlerinde invajinasyona, safra yollarına girerek kolanjit veya biliyer kolik’e neden olabilir. Biliyer sistem askariyazisinde çok sayıda çalışma yayınlanmıştır. Tüm bu çalışmalarda ultrasonografi (US), biliyer sistem Askariyazisinde temel görüntüleme yöntemi olarak belirtilmiştir. Bu yazıda, cerrahi olarak kanıtlanmış safra kaesi yerleşimli iki Askariyazis olgusunda hastalığın US görünümlerini sunuyoruz.

Anahtar sözcükler: Askariyazis, biliyer sistem, safra kesesi, ultrasonografi
