The role of simultaneous prophylactic diaphragmatic plication during major abdominal operations is evaluated. In five patients with a history of phrenic nerve injury, postoperative ventilation requirements and hospital stay were significantly reduced when synchronous diaphragmatic plication was performed, compared with corresponding values obtained during previous abdominal operation without diaphragmatic plication. In addition, diaphragmatic plication was associated with postoperative improvement of respiratory mechanics and blood gas exchange.

The number and success rate of paediatric organ transplantation continue to improve yearly, and the number of transplanted children presenting for either elective or emergency nontransplant surgery is expected to increase accordingly. The general considerations related to any transplant recipient are the physiological and pharmacological problems of allograft denervation, the side effects of immunosuppression, the risk of infection, and the potential for rejection. Preoperative assessment of transplant recipients undergoing non-transplant surgery should focus on graft function, the risk of infection, and function of other organs. Local, regional, or general anaesthesia can be safely delivered to transplant recipients. Specific anaesthetic considerations related to the type of transplantation, have an impact directly on anaesthetic and perioperative management. Since anaesthetists and surgeons in hospitals who are not involved in transplantations, may be required to manage paediatric transplant recipients, the reviews of the existing experience in this field will be valuable tools in their hands.

A retrospective study of 80 patients operated on for hydatid cysts located on the superoposterior aspect of the right lobe of the liver (segments VI, VII, VIII) is presented. Right thoracotomy was performed in 30 patients, and 50 patients were operated on through bilateral subcostal incisions. The two approaches were compared in terms of radicality and morbidity. The transabdominal approach produced superior results and fewer postoperative complications, resulting in a shorter hospital stay (11 +/- 5 vs. 18 +/- 8 days). Total cystopericystectomy was feasible in 30% of patients operated on transabdominally and in 6% of those approached transthoracically. The rest of the patients were offered partial pericystectomy, except three in the thoracotomy group who underwent simple drainage of the cavity. We recommend that the transabdominal approach be the first choice for treatment of liver hydatid cysts irrespective of their location and size. We abandoned the transthoracic approach for cysts located on the superoposterior aspect of the right liver lobe in 1996. The transabdominal approach enables the surgeon to treat liver hydatidosis in a more radical, safer manner than does the transthoracic approach.

The objective of this retrospective study was to explore the accuracy of preoperative diagnostic methods and the efficacy of treatment for cystic pancreatic tumors. From 1989 to 1999, 18 patients underwent surgery for cystic tumor of the pancreas, classified as follows: one serous cystadenoma, eight mucinous cystadenomas, six mucinous cystadenocarcinomas, and three nonfunctioning islet cell tumors. Computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), and fine needle aspiration were performed and subsequently reviewed retrospectively by two radiologists. Three patients underwent the Whipple procedure and 14 and 1 patients underwent distal and central pancreatectomy, respectively. CT showed cystic pancreatic tumors in all cases. One case was misdiagnosed as a pseudocyst. The diagnosis was accurate in 82%, 53%, 37%, and 60% of cases on CT, ERCP, and angiography, and in the cytologic analysis of the aspirated fluid, respectively. All operative procedures were performed without significant morbidity and there were no postoperative deaths. Preoperative diagnosis of cystic pancreatic tumours is imprecise. CT is the most reliable preoperative imaging method. Resection should be the treatment of choice for these lesions, except in cases of serous cystadenoma.
