What features on intraoperative cholangiogram predict endoscopic retrograde cholangiopancreatography outcome in patients post cholecystectomy?

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure performed to remove bile duct stones. Intraoperative cholangiography (IOC) is often performed at the time of cholecystectomy to determine the presence of intraductal stones. However, many of the ERCP procedures performed for this indication fail to find any intraductal stones. Given that ERCP carries significant patient morbidity, we investigated whether there are features on IOC that can guide ERCP patient selection. METHODS: A retrospective analysis of 152 patients who had an IOC filing defect and a subsequent ERCP was performed. RESULTS: Small single stones greater than or equal to 4.5 mm on IOC can be used to predict the presence of stones on a subsequent ERCP. Furthermore, ERCPs performed for single filling defects smaller than 4.5 mm are more likely to be negative if performed later rather than earlier, suggesting that small stones can pass over time. We show that 80% of these stones will pass by 11 days after the IOC. CONCLUSION: Single small stones on IOC should be given adequate time to pass into the intestine. Imaging should be performed to determine if the stone has passed into the intestine after day 11 prior to performing a therapeutic ERCP.

Pseudocyst of the pancreas masquerading as spontaneous pneumomediastinum.

Pseudocyst of the pancreas extending into the thorax represents a rare but potentially catastrophic diagnosis. It can be difficult to both diagnose and manage, with only limited management suggestions within the literature. While pleural effusion is a common complication of pancreatitis, transthoracic extension of a pseudocyst is a rare phenomenon. Herein we discuss a patient with a difficult to recognize extension of pancreatic pseudocyst into the left hemithorax, with unique imaging findings. He had good response to trans-gastric and percutaneous drainage and ultimately proceeded to thoracotomy and decortication. Around this case, the options for investigation and management are discussed.

Approach to a large rare diaphragmatic hernia in a patient undergoing cardiac surgery.

Hernia of Morgagni is an unusual congenital defect of the sternal portion of the diaphragm. Its concurrence with cardiac surgical pathology is rarely described in the literature. Notwithstanding, huge hernia of Morgagni have been noted to cause serious peri-operative impediment and complications. We report the case of a 50-year-old gentleman with a massive Morgagni hernia that threatened strangulation during cardiopulmonary bypass. We describe the combined surgical approach undertaken to repair this hernia, with an accompanying review of the literature relating to misadventure and management of similar large hernia coinciding with cardiac surgery.
