Diagnostic value of ultrasonographic examination for nonalcoholic steatohepatitis in morbidly obese patients undergoing laparoscopic bariatric surgery.

Background: There are few data relating to the role of fatty score (FS) and modified fatty score (MFS) in ultrasonographic (US) examination on the diagnosis of nonalcoholic steatohepatitis (NASH) in patients undergoing bariatric surgery.

Methods: We investigated consecutive patients undergoing laparoscopic bariatric surgery with biopsy-proven nonalcoholic fatty liver disease. Patients with other liver diseases and significant alcohol consumption were excluded.

The influence of Helicobacter pylori infection and corpus gastritis on the postoperative outcomes of laparoscopic vertical banded gastroplasty.

Background: Helicobacter pylori (HP) infection is linked to weight control through gastric inflammation-induced deregulation of satiety-related hormone, and eradication of HP before a weight reduction operation has been advocated. We aimed to examine the impact of HP infection and corpus gastritis on preoperative patient characteristics, postoperative complications and weight loss following laparoscopic vertical banded gastroplasty (LVBG).

Methods: A prospective cohort of 152 patients undergoing LVBG was enrolled.

Pedunculated hepatic hemangioma: report of two cases.

Pedunculated hepatic hemangioma may be confused with pedunculated hepatocellular carcinoma (HCC) in clinical practice because of their similar ultrasonographic pattern. We report two cases of asymptomatic pedunculated hepatic hemangioma. Both patients presented with intraabdominal masses of unknown nature measuring about 5 cm in diameter.
