Most surgeons perform coronary bypass surgery with the aid of cardiopulmonary bypass, which inflicts a massive systemic inflammatory response to the body leading to adverse clinical outcome. In an attempt to make CABG less invasive, interest have been diverted to the off pump technique.The current review attempts to bring an insight onto the last ten years knowledge on the off-pump impact in end organ function, with an aim to draw some clear conclusions in order to allow practitioners to reflect on the subject.
Blunt neck trauma can be caused by a variety of injuries such as deceleration, road traffic accidents and crush injuries. The worst scenario is airway rupture. We report an unusual case of acute tracheal injury in a 34-year-old Irish man who presented with a history of strangulation while working with a tractor. On arrival, he had one episode of mild haemoptysis and reported pain around the base of the neck and voice hoarseness. His chest X-ray revealed pneumopericardium and CT of thorax showed airway oedema. After elective intubation, positive end-expiratory pressure (PEEP) of 5 cm H2O caused deterioration in his clinical condition with increasing surgical emphysema and rise of carbon dioxide partial pressure (PaCO2), which was completely reversed after stopping PEEP. This case shows how PEEP and intermittent positive pressure ventilation can worsen air leak and compromise stability in patients with acute tracheal injury.
A 12-year-old boy was referred to the surgical unit with 4 h history of severe lower abdominal pain and bilious vomiting. No other symptoms were reported and there was no significant medical or family history. Examination revealed tenderness in the lower abdomen, in particular the left iliac fossa. His white cell count was elevated at 19.6×10(9)/L, with a predominant neutrophilia of 15.8×10(9)/L and a C reactive protein of <0.3 mg/L. An abdominal X-ray revealed intraperitoneal gas and a chest X-ray identified free air under both hemidiaphragms. Subsequent diagnostic laparoscopy identified a perforated duodenal ulcer that was repaired by means of an omental patch. The case illustrates that although uncommon, alternate diagnoses must be borne in mind in children presenting with lower abdominal pain and diagnostic laparoscopy is a useful tool in children with visceral perforation as it avoids treatment delays and exposure to excess radiation.
SUMMARYBile duct injuries are a recognised complication of cholecystectomy and a number of options exist for their evaluation. A 44-year-old woman presented with a suspected biliary leak 11 days following an open cholecystectomy. Her medical history was significant for biliopancreatic diversion 2 years previously. An ultrasound scan demonstrated a perihepatic collection but no dilation of the biliary tree was observed. The patient's surgical history and the lack of biliary dilation precluded an endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography, and she could not undergo an MR cholangiopancreatography due to claustrophobia. A CT cholangiogram was performed and clarified the location of the injury, facilitating operative identification and repair of the bile duct. CT cholangiography performed as a dynamic procedure is useful as a means of identifying bile duct injuries.
BACKGROUND
Background/Introduction Cytomegalovirus (CMV) enteritis post coronary artery bypass grafting (CABG) has been previously reported but never in an immunocompetent patient not on steroid therapy preoperatively.
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.
