We report three cases of biliary obstruction caused by a juxtapapillary duodenal diverticulum that were treated by excision of the diverticulum. A 72-year-old man, a 77-year-old woman, and an 81-year-old woman each presented with recurrent obstructive jaundice. Diagnostic imaging revealed a juxtapapillary duodenal diverticulum compressing the common bile duct (CBD). Following cholecystectomy, the diverticulum between the intrapancreatic CBD and pancreatic parenchyma was isolated and excised successfully in each case. The patients have been followed up for 34, 31, and 22 months, respectively. In one patient, choledocholithiasis developed 33 months after the surgery, necessitating endoscopic sphincterotomy. Duodenal diverticulectomy is a useful procedure to relieve biliary obstruction caused by a juxtapapillary duodenal diverticulum. However, it remains unclear whether excision of the diverticulum is preferred to biliodigestive anastomosis from the point of view of long-term prognosis. Subsequent surveillance is necessary.
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.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
