    Notes: Abstract We report a 68-year-old female patient with intrahepatic stones in the right posterior inferior segment, the right anterior superior segment, and the caudate lobe. She had previously undergone distal gastrectomy, cholecystectomy, and choledochoduodenostomy. Advanced liver cirrhosis had been diagnosed at the previous laparotomy, and cholangioscopic lithotomy through a T-tube sinus tract was therefore performed. The stones in the right posterior inferior segment and the right anterior superior segment were easily extracted. However, removal of the stone in the caudate lobe was difficult and necessitated 11 sessions of cholangioscopy. Although reports of intrahepatic stones in the caudate lobe are unusual, modern diagnostic imaging modalities may identify more such cases.

    Notes: Abstract: We report a case of aneurysmal rupture of the pancreaticoduodenal artery successfully treated by transcatheter arterial embolization. A 61-year-old man with a history of hypertension underwent surgery at our hospital in November 1995 for local peritonitis caused by perforation of the sigmoid colon secondary to cancer. On the 9th postoperative day, he developed shock, with complaints of epigastric and back pain. Abdominal computed tomography showed an enhanced mass, thought to be a peripancreatic aneurysm. Emergency angiography demonstrated an aneurysm arising from the arcade of the anterior pancreaticoduodenal artery. After diagnostic angiography, transcatheter arterial embolization was performed. With steel coils, the anterior superior pancreaticoduodenal artery and anterior inferior pancreaticoduodenal artery were embolized near the origin of the aneurysm. Angiography 7 weeks later revealed no recanalization of the aneurysm and the absence of anomalous collateral vessels. The patient has been well for 19 months without re-bleeding or recurrence of sigmoid colon cancer. Transcatheter arterial embolization is an effective therapeutic approach for aneurysm of the pancreaticoduodenal artery and is the preferred initial treatment.

    Notes: Abstract. Pharyngeal and upper esophageal sphincter (UES) manometry was performed in 15 patients with esophageal achalasia and compared with that in 10 healthy controls. Neither the pharyngeal contraction pressure nor the UES resting pressure were significantly different between the two groups, although the UES residual pressure in patients with achalasia was significantly increased compared with that in controls. Pneumatic dilatation of the lower esophageal sphincter (LES) was performed in these patients. After successful LES dilatation, the increased UES residual pressure in patients with esophageal achalasia decreased significantly. Our results suggest that UES relaxation in patients with esophageal achalasia is incomplete compared with that in healthy adults. This UES abnormality is not a primary defect but a secondary phenomenon.
