Stomach carcinoma is more common disease in korea than western contries. The reported ultrasonographicfindings of gastric carcinoma were thickening of gastric wall and “pseudokidney” sign. The auther analizedultrasonographic findings of 101 cases with gastric carcinoma who were performed ultrasonography and gastroscopyat Kyung Hee Universtiy Hospital from Oct. 1982 to Oct. 1985. The results were as followings; 1. Types of gastriccarcinoma were consisted with infiltrative type 68 cases, infiltrative type with ulceration 16 cases, polypoidtype with ulceration 1 cases, infiltrative and polypoid type 4 cases, linities plastica type 3 cases, lcerativetype 1 case and polypoid type 1 case. 2. Extent of the lesions were in body and antrum 45 cases, entire stomach 18cases, antrum 18 cases, body 12 cases, body and fundus 6 cases. 3. Ultrasonography was useful in demonstrating theextent of the tumor and the presence of materials elsewhere in abdoment.

The authors report a xase of primary non-gestational choriocarcinoma(PNGCO) of the ovary in a prepubertal female patient and reviewed. It is an extremely rere disease of which incidence is one in 369 million. Major clinical symptom is abdominal pain, precociois puberty and it can be misdiagneosed as ectopic pergnancy. Distinction from gestational choriocarcinoma(GCO) of the ovary is important because of the worse prognosis of PNGCO. But no distinctive ultrastructural or immunohistochemical differences are found between PNGCO and GCO. Most acceptable treatment modality is an aggressive surgical therapy and systemic chemotherapy, but its progrosis is poor.

There have been many debates concerning operative decompression of treatment of thoracolumbar burst fractures with retropulsed bone fragment. From March 1988 to February 1992, authors treated thirty-three thoracolumbar burst fractures by using transpedicular screw fixation and posterior fusion via the posterior approach. We attempted to reduce retropulsed fragment by ligamentotaxis alone and not to do posterolateral nor anterior decompression. After the reduction of fractured spine by posterior instrumentation, we tried to determine the efficiency of reduction of the retropulsed fragment by ligamentaxis along. As a method, we compared the change of anteroposterior, transverse to diameter and area of spinal canal of fractured spine between preoperative and the postoperative situation. The results were as follows; 1. The mean anteroposterior and transverse diameter of the spinal canal on computed tomogram film was 10.1mm & 21.8mm preoperatively & 12.4mm & 23.2mm postoperatively, showing an increase. 2. The area of spinal canal of involved spine on CT film was evaluated preoperatively & post-operatively, the mean spinal canal invasion rate decreased from 36.3% preoperatively to 14.3% postoperatively. 3. The degree of reduction of middle height on plain x-ray and reduction of spinal canal invasion on computed tomogram were statistically correlated(p < 0.01). 4. There was no correlation between the degree of canal narrowing and degree of neurologic impairment. also, there was no correlation between the reduction of retropulsed fragments and subsequent neurologic impairment. 5. There was the relatively satisfactory enlargement of the spinal canal on computed tomogram at the follow-up So we suggest that it is possible to get enough decompression through reduction of retropulsed fragment by ligamen to taxis alone without posterolateral decompression.

Authors analyzed CT findings of 8 patients with tuberculous lymphadenitis and one case of tuberculous abscessdiagnosed surgically or clinically. The results were as follows; 1. Soft tissue density masses were noted in 8patients in paraaortic, mesenteric, peripancreatic, celiac, porta hepatis, and esophagogastric junction areas inorder of frequency, and these correspond to lylmph node groups of the same name. On contrast enhanced CT, rimenhancement with multilocular low dinsties indicating caseous necrosis were noted in 3 patients, ill defined lowdensities were seen in 3 patients, and no definite changes were noted in 2 patients. 2. Two or more lymph nodegroups were involved in 6 patients, and one lymph node group was involved in two patients. 3. A huge cystic masswith relatively irregular rim enhancement and small anount of solid component occupied nearly entire upper abdomenin 1 patient and this was confiremd as tuberculous abscess in peritoneum. 4. In 2 cases, bowel wall thickening wassuggested in cecum, ascending colon, and terminal ileum.

The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In atotal of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showedinternal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is notpossible in ultrasound. The possibility of mucocele shold be considered if cystic mass in right lower quadrantabdomen is observed in ultrasound.

The survival of patients with gastric cancer is improved by early diagnosis and surgical treatment. However, there is no established treatment for locally recurrent cancer or cancer arising at an anastomotic site after total gastrectomy; further, most surgeons are reluctant to resect this type of cancer because of frequent systemic metastasis and there are few competent surgeons who have the skill to perform such an operation. We have experienced recurrent cancer at an anastomotic site after total gastrectomy: one patient had recurrent cancer and two patients had metachronous cancer. All these patients were operated on and the patients were discharged without any complications. All of them are alive at the time of this report. In some cases, good results could be expected for operating on recurrent cancer of an anastomotic site after previous total gastrectomy. So, we present here our experience along with a review of literatures.

Postoperative chylothorax following an injury to the thoracic duct during an esophagectomy is a rare, but severe complication, which may lead to serious problems, such as loss of fat and proteins, as well as immunodeficiency. Left untreated, the rate of mortality can rise to over 50%. Herein, 3 patients were treated with a postoperative chylothorax following 280 resections of the esophagus (0.1%). One patient underwent a direct injured thoracic duct ligation by a re-thoracotomy. In the other two patients, relaparotomy and transabdominal double ligation of the thoracic duct were performed. After ligation of the abdominal thoracic duct, the average amount of chyle was markedly reduced. Two patients were discharge from hospital without problems after 36 and 30 days, respectively. Ligation of the thoracic duct, via a relaparotomy, appears to be a simple and safe method for the treatment postoperative chylothorax.

The Brunner's gland adenoma is characterized by a nodular proliferation of histologically normal Brunner's gland, accompanied by ducts and scattered stromal elements. First descrived by Salvioli in 1876, the tumor is relatively rare, with 119 cases reported by 1977, The most common benign tumor of the small bowel is the adenoma, 25% of which occur in the duodenum. They make up 30% to 50% of all hyperplastic polyps of the duodenum. Most frequently these tumors are discovered in patients in the fourth to sixed decades of life, though the age in reported caes ranges from l 1 days to 80 years. The benign tumors of the duodenum 30% to 50% contain elements of Brunner's gland and 10.6% of them are adenomas of Brunner's gland. We report a case of Brunner's gland adenoma treated by endoscopic polypectomy in 63 year-old woman, and reviewed the literatues of adenoma of the Brunne'r gland.

A case of mucinous cystadenocarcinoma arising from a mature cystic teratoma in the right ovary of a 37-year-old woman is reported. Malignant transformation of a mature teratoma is a rare event and the commonest malignant neoplasm to develop is squamous cell carcinoma.(83%) Adenocarcinoma occurs with less frequency.(6.8%) The patient was treated by staging operation followed by adjuvant chemotherapy. After six courses of combination chemotherapy, oncological investigations, including chest X-ray, abdominopelvic CT scan and tumor markers, all revealed no evidence of recurrence.

The purpose of this study was taken after transplantation of fetal serotonin and substance-P containing raphe nuclei into the transected thoracic spinal cord (T9-10) of adult rats, a suspension of cells derived from the mesencephalic and medullary raphe nuclei of 13~15 days embryonic rats were injected upper and lower the transected spinal cord. After survival periods of 15 days to 1 year, the animals were sacrificed and the spinal cord, processed for the localization of serotonin and substance-P immunoreactive neurons in the transplanted spinal cord, was studied using ABC immunocytochemistry. Immunocytochemical analysis revealed the presence of many serotonin and substance-P immunoreactive neurons in the transplants. In the mesencephlic implants, however, the serotonin and substance-P immunoreactive neurons were not co-localized with the same neurons. The serotonin and substance-P nerve fibers were densely distributed in lamina I and II of the dorsal horn and in lamina VIII and IX of the ventral horn of all segments of the spinal cord. The nontransplanted control, spinal cord of the rats showed a total absence of serotonin and substance-P immunoreactive fibers below the section. Immunoelctronmicroscopic anlysis demonstrated the presence of numerous synaptic contacts formed by serotonin and substance-P containing boutons which are most likely emanated from the grafted serotonin and substance-P.
