Hemorrhage complicating simple liver cyst is rare. On imaging studies, the differential diagnosis between intracystic hemorrhage and cystadenocarcinoma of the liver is unreliable, and hepatectomy has been performed for benign liver cyst in this situation. We describe the characteristics of hemorrhage into a liver cyst in a patient who underwent dome resection of the cyst. In our patient, important diagnostic findings included benign cytologic features in a cyst fluid specimen aspirated with ultrasonographic guidance and a fall in hemoglobin and hematocrit, suggestive of hemorrhage. Other informative features were absence of communication between the intrahepatic bile ducts and the cystic liver lesion upon endoscopic retrograde cholangiopancreatography, as well as benign intraoperative frozen-section histology.

Bile duct injuries are a potential complication of laparoscopic cholecystectomy (LC). A patient who underwent successful endoscopic nasobiliary drainage (ENBD) for a bile duct injury sustained during LC is presented. Of particular note, the patient also had Chilaiditi's syndrome. A 59-year-old woman was admitted with symptomatic cholecystolithiasis and Chilaiditi's syndrome. LC was performed. Postoperatively, the patient complained of abdominal discomfort. Laboratory examination revealed cholestasis. Bilious material began spilling from an intraabdominal drain. Subsequent endoscopic retrograde cholangiopancreatography (ERCP) showed bile leakage. ENBD was performed. Repeat ERCP 10 days later failed to show a bile leak or stenosis of the common bile duct. The patient improved rapidly and had no complaints after the procedure. ENBD is a useful endoscopic technique to prevent peritonitis from bile leakage after LC. Chilaiditi's syndrome is not a contraindication for LC.

Churg–Strauss syndrome (CSS) is a systemic vasculitis occurring in patients with a history of asthma. Wells' syndrome (WS) is a rare inflammatory dermatosis that clinically resembles cellulitis, and is histologically characterized by eosinophilic infiltration and flame figures. We report a case of WS associated with CSS. There have been three previous reports of WS associated with CSS; ours is the fourth. All cases had bullous lesions, and three cases were positive for antineutrophil cytoplasmic antibodies.

Transabdominal US can play a role in screening for esophageal varices. The intraabdominal esophagus should be observed during standard abdominal US in patients with chronic liver disease.

A retrospective study of 155 patients with submucosal gastric carcinoma compared the clinicopathologic features with mucosal and muscularis proprial gastric carcinoma. Fifty-seven percent of the patients presented with gastrointestinal symptoms, whereas 36.1% had been detected by mass screening. The incidence of curative resection, lymph node metastasis, and complications were 96.1, 20.6, and 14.8%, respectively. Two patients died of sepsis and pulmonary infarction 30 days post-operatively. Five patients died of recurrent gastric cancer 1-5 years postresection. The overall 5-year survival rate was 90.2%. Recurrence patterns, histologic type, lymph node metastasis, lymphatic and venous infiltration, and growth pattern were similar to those of muscularis proprial carcinoma rather than mucosal carcinoma. Therefore, curative gastrectomy with extended lymphadenectomy (D2) may be feasible for submucosal carcinoma of the stomach.
