Study of swallowing sound at the esophagogastric junction before and after fundoplication.

INTRODUCTION: Swallowing sounds can be heard in the lower esophagus by xiphoid auscultation. We hypothesize that the xiphoid sound analysis could provide information concerning the integrity of the esophagogastric junction (EGJ), i.e., superposition of the lower esophageal sphincter (LES) and the diaphragm to assess clinical diagnosis of gastroesophageal reflux disease (GERD) and results of Nissen fundoplication (NF). The aim was to evaluate the changes in sound parameters using our acoustic technique after reorganization of the EGJ after NF. METHODS: For 21 patients with GERD and hiatus hernia, two microphones were placed below the cricoid and on the xiphoid cartilages. The frequency and duration of xiphoid sounds, esophageal transit time were calculated. We defined the xiphoid sound as composed of vibration groups separated by periods >100 ms. The number of vibration groups, number of vibrations per group, and interval between groups were also calculated. RESULTS: The xiphoid sound frequency was increased after NF, and the esophageal transit time and xiphoid sound duration were significantly decreased. A significant correlation was found between xiphoid sound duration and LES-diaphragm displacement. The number of vibration groups and interval between groups were reduced after NF. CONCLUSION: The acoustic technique for swallowing revealed the effects of NF upon the dynamic profile of the EGJ. The organization of vibration groups at the EGJ suggested that the passage of the bolus was modified by hiatus hernia, i.e., dissociation between the LES and the diaphragm and regularized by NF. Concomitant acoustic and radiologic study should contribute to better understanding of sound related to EGJ structure and boli.

Thirteen-year disease-free survival after surgery for cystic duct carcinoma: a case report.

Cystic duct carcinoma is known to have a better prognosis compared to its location in other biliary ducts. Only one case with a survival over ten years has been previously published. The authors report a case of survival over 13 years without recurrence or metastasis. Preoperative diagnosis of cystic duct tumor was carried in a 66-year-old male. Under the diagnosis of carcinoma of the cystic duct, the patient underwent en bloc resection of the gallbladder, cystic duct, hepaticocholedochus and lymph node dissection. A Roux-en-Y hepaticojejunostomy was performed. Histological examination revealed a moderately differentiated adenocarcinoma of the cystic duct. Five months later the patient underwent second look surgery for benign obstruction of the hepaticojejunal anastomosis. The patient is still doing well 13 years later without any local recurrence or metastasis. To our knowledge, this is the longest disease-free survival ever published in the literature. This case sustains that better and longer survival is possible with a real chance of potential cure if radical surgery is performed.

[Acute pancreatitis related to hemobilia complicating hepatocarcinoma]. / Pancréatite aiguë liée à une hémobilie compliquant un carcinome hépatocellulaire.

Hemobilia is an rare cause of acute pancreatitis. The most frequent causes are iatrogenic trauma (percutaneous liver biopsy) and hepatic artery aneurysm. To our knowledge, this is the second published case of acute pancreatitis related to hemobilia secondary to hepatocarcinoma complicated cirrhosis in a patient treated with anticoagulants for a mechanical valvular aortic prosthesis. The clinical picture included acute epigastric pain, fever and jaundice. Increased amylase and lipase serum activities, and abdominal CT data confirmed the diagnosis of acute pancreatitis. Gallstone induced acute pancreatitis was suspected and thus, a cholecystectomy was performed. No bile duct stones were found but a clot was extracted from the extrahepatic bile duct during surgery. Arterial embolization was then performed and repeated 1 and 3 months later for recurrence. The patient was asymptomatic eight months later. Hepatic arterial embolization is an effective haemostatic treatment for hemobilia, even though, in this case treatment had to be repeated because of an anticoagulant therapy.
