Pheochromocytomas are catecholamine-producing tumors that typically cause hypertension. They are rare tumors that can pose problems in diagnosis and detection. Although they usually present classic symptoms, they can at times present symptoms that mimic other clinical conditions. Especially, children have fewer malignant tumors, non-extra-adrenal tumors, and tumors with greater bilaterality and multiplicity. The diagnosis of pheochromocytomas is based upon clinical suspicion and biochemical study. Radiologic localization is obtained before operation because of the variable location of this tumor. The treatment of choice is surgical resection. We reports a case of asymptomatic pheochromocytoma that was treated with tumor excision. To prevent intraoperative and postoperative complications, precise preoperative diagnosis and localization, as well as adequate preoperative management, are necessary.

BACKGROUND: It is controversial whether the delay of surgery for acute appendicitis by physician results in higher morbidity. Our present study explores this problem of physician delay on the postoperative outcome of patients with acute appendicitis. MATERIAL AND METHODS: Among 432 patients admitted for the presumptive diagnosis of acute appendicitis between Jan., 1995 and Dec., 1997, 358 patients with pathologically proven acute appendicits were analyzed. Physician delay from the hospital admission to the surgery was evaluated in relation to the stage of the disease at operation and postoperative outcome. RESULTS: Postoperative complications occurred signifficantly higher in advanced appendicitis group, than in simple appendicitis group. Postoperative oral consumption started significantly later and hospital days are significantly prolonged in those group. Both patient and physician delays significantly affect the stage of the disease. The finding that physician delay correlated with the stage, however, was denied by multivariate analysis. CONCLUSION: On the contrary to the patient delay, physician delay does not affect the stage of the acute appendicitis nor lead to increased incidence of postoperative complication. Physician delay to clarify the diagnosis is a reasonable strategy and it does not affect the outcome adversely.

Pulmonary infection after renal transplantation is a well recognized and prevalent postoperative complication, which can occur at either the early stage or late stage after transplantation. The etiology and this phenomenon and its impacts remains unclear. It may be life-threatening in severe patients. Early diagnosis and treatment are important; meanwhile, the dosage of immunosuppressant should be minimized. Prophylactic management should also be emphasized.

Hypertension is a common complication after renal transplantation. Among post-transplantation patients died of cardiovascular diseases, about 41% have hypertension. Hypertension is an independent risk factor for kidney transplant failure. Post-transplantation hypertension can be caused by many factors, including the use of immunosuppressants. When the blood pressure exceeds 130/90 mmHg in a kidney transplant recipient, it is reasonable to provide active medical intervention. In summary, prevention and treatment of hypertension is important to prolong the survival of kidney transplant recipients.

Chyle leak is a rare complication after abdominal surgery. According to the statistical results from our center, we summarized the experiences in the diagnosis, treatment and prevention of abdominal chyle leak after radical resection of colorectal cancer. Early prevention, early diagnosis, and early treatment may result in earlier recovery, shorter hospital stay, lower incidence, and better prognosis.

PURPOSE: To investigate the causes and to determine the most useful test for the early diagnosis of infected TKRA, and to present the treatment modality and its possible complications. MATERIALS AND METHODS: We reviewed 17 cases, with follow up, among the 18 infected TKRA cases registered from March 1992 to June 2000. Diagnosis of deep infection after TKRA was made by assessing clinical symptoms, laboratory and radiological findings, nuclear scan studies and aspirate culture results. Data were analyzed clinically by HSS score, recurrence of infection and postoperative complications. RESULTS: The overall incidence of deep infection after TKRA was 1.4%. In fourteen of the 17 cases TKRA was revised. In 13 cases, excluding 1 case of infection recurrence after 2-stage TKRA revision, the mean ROM increased from 55o to 86o and the mean HSS score increased from 53 points to 84. Knee fusion was performed in 4 cases, including one case of infection recurrence after 2-stage TKRA revision. CONCLUSION: The most reliable clinical results were achieved after a 2-stage TKRA revision. Knee joint fusion should be considered when the general condition is poor, with an initial diagnosis of infection, and in the presence of skin problems.
