An exceptional case of neurilemmoma in a 33-year-old asymptomatic man is described. Complete excision of an encapsulated 7.2-cm mass was achieved successfully. Pathological findings were consistent with a diagnosis of schwannoma with areas of sclerosis.
The most important preoperative cardiopulmonary variables for identifying patients at increased risk prior to lung resection are: FEV1, FEV1-ppo, DLCO, MVO2, and SO2. The aim of this study was to evaluate the ability and usefulness of predictive postoperative FEV1 (FEV1-ppo) in 80 patients undergoing lung resection. Spirometry was performed before and 6 months after operation; residual respiratory function was calculated using Nakahara's formula, and data analysis calculations were performed using the chi 2 test. It was observed that the resulting predictive values were almost comparable to the values observed 6 months postoperatively in 63.75% of patients and the correlation proved statistically significant (P < 0.005). In view of its simple and rapid execution, we conclude that Nakahara's formula, compared with the others, remains a reliable standard method of assessing high-risk patients and planning appropriate surgery.
Twenty-five percent of patients undergoing surgery for acute complicated diverticulitis represent emergencies. This condition is currently treated by colonic resection with primary anastomosis with or without colostomy, or by a Hartmann operation. We report on our experience with 52 consecutive patients with generalized peritonitis (8 cases), peri- and paracolonic abscesses (19 cases), severe pelvic abscesses (12 cases) and multiple abscesses with visceral fistulas (13 cases). All patients had emergency surgery. In 50/52 patients (96.2%) we performed a colonic resection with primary anastomosis using a mechanical stapler and in 2/52 a Hartmann operation. The overall mortality rate was 5.8%. The morbidity rate was 22% with 9 anastomotic leakages. A diverting colostomy was constructed in 16 patients and opened in only 8 patients. In 4 cases a parastomal hernia occurred after late closure and reduction of the colostomy. This data suggest that colonic resection with primary anastomosis, even without colostomy, is a safe procedure for the emergency treatment of acute complicated diverticulitis.
