[Complication during the period of anuria after cadaveric transplantation--with special reference to wound bleeding].

Some period of anuria is usually expected after cadaveric renal transplantation, and hemodialysis is necessary during the period. Postoperative bleeding in the anuric period is not uncommon and usually can be easily controlled with adequate conservative treatment. However, it becomes uncontrollable in some cases and causes a series of serious complications. Out of 22 patients having undergone cadaveric renal transplantation in our hospital, six patients had postoperative bleeding. On investigation of these cases, we found that not only a hemorrhagic tendency due to uremia but also hemodialysis is a risk factor of bleeding in the wound.

[Effect of valve replacement on left ventricular function in chronic aortic regurgitation].

To ascertain the optimal time for surgery in chronic aortic regurgitation (AR), 66 patients with and without surgical correction were reviewed from the standpoint of left ventricular (LV) function based on their serial echocardiographic studies. Aggravation of the clinical status was usually associated with enlarged LV dimension, decreased %fractional shortening (%FS), and increased LV end-systolic meridional stress (sigma m). Fourteen patients developed congestive heart failure during follow-up periods of up to five years, and most of their echocardiographic findings showed %FS less than 27%, and LV end-systolic dimension (LVD) greater than 50 mm. Thirty-two patients underwent surgery. Preoperatively, sigma m and %FS were closely correlated, including cases whose %FS was decreased. This linear regression equation became steeper with dobutamine administration; however, in patients, whose mean preoperative LVD value exceeded 50 mm, the %FS remained depressed (delta FS less than 6%) and sigma m did not significantly decrease during dobutamine administration. Marked or moderate resolution of LV dilatation and hypertrophy was observed in all patients postoperatively. Compared to patients with preoperative %FS greater than or equal to 27%, much more time was required for recovery of patients with %FS less than 27%, though their %FS and their exercise capacity improved within two years of surgery. Immediate postoperative recovery was observed in cases with excellent preoperative response to dobutamine (delta FS greater than or equal to 6%). However, in patients with severely depressed preoperative %FS less than 20%, postoperative improvement was not so marked and the surgical results were unsatisfactory. From these results, we concluded that the optimal time for surgery for AR is when %FS = 27% and LVDs = 50 mm.

[A case of a perforation indicative of early gastric cancer with various macroscopic findings and a collective review of the relevant Japanese literature].

A case of perforated early gastric cancer and a collective review of the relevant Japanese literature is reported. A 83-year-old woman with free air discovered by an abdominal X-ray, was referred to our hospital. On operating, a perforated ulcer was found within and lesions, indicative of a IIc + III type early gastric cancer. Macroscopically, there was an elevated lesion at the antrum of the stomach as well. Histologically, these lesions were connected and moderately differentiated adenocarcinoma. Another lesion was also found at the anterior wall and diagnosed as IIb type gastric cancer.

[Results of treatment of primary malignant tumor of the small intestine].

The results of treatment of 40 cases of primary malignant tumor of the small intestine are reported. The malignant tumors included 14 leiomyosarcoma, 12 malignant lymphoma and 14 adenocarcinoma. Our standard treatment for these tumors was segmental resection of the small intestine with its mesentery including the regional lymph nodes and we used additional adjuvant chemotherapy for some cases of malignant lymphoma and adenocarcinoma. Curative resection was performed in 57.1% of leiomyosarcoma, 50.0% of malignant lymphoma and 61.5% of adenocarcinoma. Cumulative 5-year survival rates were leiomyosarcoma 21.4%, malignant lymphoma 53.0% and adenocarcinoma 43.3% respectively. Serosal infiltration, lymph node metastasis and operative curability proved to be the prognostic factors. In particular, the 5-year survival rate of patients on whom curative resection could be performed was significantly better for each tumor type than that of patients for whom this was not possible, the figures being leiomyosarcoma 40.0%, malignant lymphoma 83.3% and adenocarcinoma 83.3%.

[Two cases of carcinoid tumor of the stomach and a collective review of the Japanese literature].

We report two cases of carcinoid tumor of the stomach together with a collective review of the Japanese literature. Case 1 was preoperatively diagnosed as carcinoid, and the lesion, measuring 10 X 7 mm, and located in the body of the stomach, had no metastases. Case 2 was preoperatively diagnosed as gastric cancer and was recognized as a submucosal tumor measuring 5.8 X 4.7 cm in the antrum of the stomach. There were metastases to the brain and the skin, and the patient died on the 50th day after the operation. From a collective review of previous cases, it was ascertained that small carcinoid tumors sometimes had metastases. For this reason, we feel gastrectomy should be performed together with local lymph node resection.

Reduction of plasma norepinephrine levels in response to brief coronary occlusion in experimental dogs.

Although an increased plasma norepinephrine (NE) level is sometimes observed during angina pectoris, it is difficult to say whether sympathetic overflow is its cause. The left anterior descending coronary artery was occluded by intracoronary balloon for 3 minutes in 12 closed-chest anesthetized dogs. During occlusion, heart rate did not change but aortic pressure slightly decreased. Occlusion caused a significant reduction in both NE levels in the aorta (177 +/- 17 to 134 +/- 16 pg/ml, p less than 0.01) and in the great cardiac vein (GCV) 296 +/- 44 to 249 +/- 44 pg/ml, p less than 0.01). After surgical vagotomy, the occlusion increased NE levels in the aorta (227 +/- 44 to 278 +/- 43 pg/ml, p less than 0.01) and in GCV (384 +/- 76 to 444 +/- 81 pg/ml, p less than 0.01), showing the release of vagal inhibition. These results may be applicable to patients with transient anterior myocardial ischemia; if plasma NE increases without marked hemodynamic changes, it is suggested that the sympathetic overflow is not a result but a possible cause of the ischemia.
