[Left-sided gallbladder: report of a case and study of 26 cases in Japan].
A case of left-sided gallbladder with an anomaly of the intrahepatic portal vein and cholesterol polyps of the gallbladder is presented. A 23-year-old man with sudden onset of epigastric pain, fever and abdominal irritation was admitted to our hospital and an emergency celiotomy was carried out. The gallbladder lay on the left side of the round ligament, that is, it was a left-sided gallbladder. Since operative findings such as cholecystitis, gastrointestinal perforation and pancreatitis were not observed, no more procedures were done. Postoperative ultrasonography showed some interesting findings as follows: multiple echogenic nonshadowing small polypoid lesions which did not change in size and shape during a 2.5 year interval were detected and were thought to be cholesterol polyps. The tail of the gallbladder was situated on the left side of the round ligament and the motion of the gallbladder as determined by postural exchange was not floating. These findings are compatible with a left-sided gallbladder. The left branch of the portal vein did not form an umbilical portion as is usually expected and the right branch formed a cystic structure similar to a normal umbilical portion with the anterior, posterior and medial branches ramified. The round ligament arose from the cul-de-sac of the umbilical portion. Twenty-six cases of left-sided gallbladder from the Japanese literature were reviewed and discussed.
