The extent of recovery of exercise capacity at 1 year after surgery was approximately 95%. Furthermore, the anaerobic threshold per square meter of body surface area was restored to the preoperative level by 1 year after surgery.
A 33-year-old woman being treated for rheumatoid arthritis was referred to our hospital for investigation of a mediastinal mass. A chest computed tomography scan showed an anterior mediastinal mass, 8.5 x 7.0 cm in size, with a cystic lesion and calcification. These findings were suggestive of either a noninvasive thymoma or a mature teratoma. Therefore, we performed tumor resection and thymectomy. Histologically, the tumor consisted of diffuse deposits of massive eosinophilic amorphous material. The tumor was stained red-orange by Congo red, and the staining disappeared following potassium permanganate digestion. Based on these findings, a diagnosis of reactive amyloidosis of the amyloid A-protein-derived type was made. Amyloidosis in the mediastinum has rarely been described.
This method for determining a pulmonary resection procedure avoided postoperative deaths and severe cardiopulmonary complications, while achieving a good outcome.
We report a case of pancreatic injury, caused by a stab wound, in which ductal injury and wound depth were clearly identified by intraoperative ultrasonography. A 65-year-old woman was emergently admitted to our hospital after stabbing herself in the abdomen in a suicide attempt. Preoperative computed tomography (CT) and laboratory examination revealed liver and pancreatic injury with massive abdominal bleeding and free air. Operative findings included injuries of the stomach, small bowel, colon, liver, and pancreas. The pancreatic lacerations were 1 cm in length, in the body. Intraoperative ultrasonography enabled the diagnosis of a lacerated main pancreatic duct with no damage to the major vessels posterior to the pancreas. Distal pancreatectomy; simple repairs of the liver, small bowel, and stomach; exteriorization of the injured colon; cholecystostomy; gastrostomy; and jejunostomy were performed. The patient recovered and was transferred to a psychiatric hospital 87 days after surgery. In this patient, intraoperative ultrasonography was successfully used to identify the degree of injury to the pancreatic duct, as well as the depth of the stab wound. In conclusion, intraoperative ultrasonography should be routinely performed to detect main pancreatic duct injury in penetrating pancreatic trauma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations 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.
