This study was undertaken to observe the effects of centrally administred antihistamines on the blood pressure. Diphenhydramine(DPH), a H1-receptor antagonist, and ranitidine(RAN), a H2-receptor antagonist were administered intracerebroventricularly(icv) on urethane-anesthetized rabbits. 1) Both DPH and RAN administered intraccebroventricularly increased blood pressure, however the intravenous(iv) adminstration of them did not affect blood pressure. The pressor response to icv DPH was dose-dependent, but that to icv RAN was not. 2) The pressor response to icv DPH(1mg) was either markedly attenuated or reversed to depressor response by the pretreatment with icv phentolamine(250,500ug), and iv chlorisondamine(0.1, 1mg/Kg) and iv phenoxybenzamine(1mg/Kg). In cord-sectioned rabbtis, icv RAN) 1mg) did not produce pressor response. 3) The pressor responsr to icv RAN(1mg) was not affected by the pretreatment with icv phentolamine(500ug), iv chlorisondamin(1mg/Kg) and iv phenoxybenzamine(1mg/Kg), and iv phenoxybenzamine(1mg/Kg). RAN also producted pressor response in cordsectioned rabbits. These results suggest that the pressor response to icv DPH is elecited by increasing peripheral sympathetic tone via the stimulation of central alpha-adrenoreceptors and the pressor response to icv RAN is produced by releasing some humoral facotr which can increase blood pressure.

Gastric duplication is an extremely rare disease that is commonly encountered during the first and the second decades. It is usually located in the greater curvature and forms a complete cystic structure. It usually presents non-specific post-prandial abdominal discomfort or is free of symptoms. Its significance is that it is associated with gastric malignancy or gastric ulcer and is difficult to differentiate from gastric submucosal tumor. We recently encountered an unusual case of gastric duplication, which developed in a 29-year-old man whose chief complaint was chronic abdominal discomfort. With a preoperative impression of gastric submucosal tumor, we explored his abdomen and found the gastric duplication located in the greater curvature side and performed a wedge resection. He was uneventfully discharged on the 12th postoperative day.

PURPOSE: Recurrent gastric cancer has a very poor prognosis due to its diagnostic difficulties, variant recurrence patterns and no effective treatment modalities. In this study, we retrospectively analyzed treatment results of the recurrent gastric cancer. MATERIALS AND METHODS: We reviewed 1,286 patients who had taken radical surgery for primary gastric cancers and were diagnosed to have recurrences of their primary diseases. According to the medical records, we retrospectively analyzed the gross features, histologic types and TNM stages of primary gastric cancers. The symptoms, diagnostic modalities, durations, recurrence patterns, treatments and prognoses of recurrent diseases were also reviewed. RESULTS: The median survival time of total recurrent gastric cancer patients was 6.8 months. Ldegrees Co-regional and distant recurrences had better results than peritoneal and mixed recurrences (p<0.01). Curative resection of recurrent cancer was done in only 1.6% (18 cases in ldegrees Co-regional recurrence and 4 cases in distant recurrence), but in these cases, significant survival gain (5 year survival rate: 30.5%) was found compared to other treatment modalities (p<0.01). In multivariate analysis, the type of first operation, TNM stage, duration till recurrence, recurrence pattern, and treatment modality of recurrence were meaningful for the survival time after recurrence. CONCLUSION: In selective cases, recurrent gastric cancer had an effective treatment modality and was expected to have prolonged survival. Therefore, a careful diagnosis and an active treatment of the patients who have the recurrent gastric cancers should be done, especially for the ldegrees Co-regional recurrence.

PURPOSE: We compared the safety of the double-stapling method with that of the hand-sewn method when performing a Billroth I anastomosis (BI) after a radical subtotal gastrectomy. METHODS: Fifty-three (53) patients who received a BI with stapler from February 1998 to April 1999 were compared with 24 patients who received a BI with the hand-sewn method from January 1996 to December 1998. All the patients were divided into three groups according to the type of reconstruction: Group 1 (n=42), double- stapling method, Group 2 (n=11), anastomosis through posterior gastric wall, and Group 3 (n=24), hand- sewn method. The length of the greater curvature, lesser curvature, and proximal margin and the number of resected lymph nodes were compared for radicality, and the incidence of complications was reviewed. ANOVA and the chi-square test were used for the statistical analysis. RESULTS: The mean ages were 55.2+/-10.8, 59.8+/-9.7, and 54.7+/-11.9 years for groups 1, 2, and 3, respectively. The sex ratios were 2.2:1, 1.2:1, and 1.4:1. The lengths (cm) of the greater curvature were 17.2+/-2.5, 18.4+/-2.5, and 18.6+/-3.3, and the lengths of the lesser curvature were 10.4+/-1.5, 10.9+/-1.6, and 10.7+/-2.1; however, the differences were not statistically significant (p>0.05). The lengths of the proximal resection margin were 5.4+/-2.5, 8.2+/-3.3, and 6.0+/-3.2 (p<0.05), and the numbers of resected lymph nodes were 25.3+/-8.3, 19.1+/-5.8, and 32.+/- 13.7 (p<0.01). We experienced no complication in any group, except one case of leakage in the hand-sewn group. CONCLUSION: The double-stapling technique is a safe operative method in BI after a radical subtotal gastrectomy with its very low complication rate. Especially, the so- called Tornado method is a more useful method since it doesn't need a gastrotomy in the remnant stomach.

Traumatic optic neuropathy is a challenging emergency; controversies involving definition, natural history, pathomechanisms, and treatment modalities make its management problematic. Surgical decompression does not always yield favorable results; if this approach is considered, however, a careful evaluation of the necessary extent of invasion, the patient's condition(including a compromised brain) and the surgeon's familiarity with the procedure must all be carefully considered. We managed two traumatic optic neuropathy patients whose vision had been lost after fracture of the medial orbital wall. Using a nasal endoscope, the endonasal approach was employed, and endoscopic optic nerve decompression was performed; visual acuity was partly recovered. This precedure can be used in patients with decreased visual acuity due to traumatic optic neuropathy involving fractures of the optic canal. It is considered minimally invasive, has no specific contraindication, and can be used in patients whose brain condition is compromised.

PURPOSE: This study was designed to investigate the clinicopathologic factors related to peritoneal recurrence and to predict peritoneal recurrence based on clinicopathologic factors. METHODS: A retrospective analysis of 383 patients with peritoneal recurrence, out of 4184 patients who had undergone curative gastric resection at SNUH from 1986 through 1996 was done. RESULTS: Of the patients with peritoneal recurrence, 275 (71.8%), 97 (25.3%), and 11 (2.9%) were early (0~24 months), intermediate (24~60), and late (more than 60) recurrence, respectively. In multivariate analysis, serosal invasion, lymph node metastasis, size of tumor, Borrmann type, perineural invasion and sex were independent prognostic factors for peritoneal recurrence. After classifying all patients into 16 groups on the basis of 4 factors, serosal invasion, lymph node metastasis, Borrmann type, and size, the number and proportion of a patients with peritoneal recurrence was obtained. There was 4.2% peritoneal recurrence in the most favorable group (n = 71), which had a Borrmann type 1 or 2 lesion less than 5 cm in maximal diameter with neither serosal invasion nor lymph node metastasis. There was a 25.4% peritoneal recurrence in the most unfavorable group (n = 331), which had a Borrmann type 3 or 4 lesion more than 5 cm with serosal invasion and lymph node metastasis. CONCLUSION: Our results suggest that patients with a Borrmann 3 or 4 lesion more than 5cm in maximal diameter, with serosal invasion and lymph node metastasis have thehighest risk for peritoneal recurrence. These patients could be considered as candidates for a treatment modality such as intraperitoneal chemotherapy or hyperthermic chemotherapy.

PURPOSE: We wanted to determine the incidence of HGC (hereditary gastric cancer) in Korean under the minimal criteria of ICG-HGC (International Collaborative Group on Hereditary Gastric Cancer). MATERIALS AND METHODS: Tumor registry abstracts of 1752 patients who underwent operations for gastric cancer during the time period 1996 to 1998 in the Department of Surgery at Seoul National University College of Medicine were examined. Based on their family histories, candidate HGCs were identified. Their detailed family histories including diagnosis of cancer, age at diagnosis, and dates of birth and death were obtained from interviews by phone. Another study was performed on 195 patients with gastric cancer who admitted for operations in the same department during the time period April, 1999 to June, 1999. Their detailed family histories were also obtained from probands or nearest relatives during admission. Pedigree studies of documented families were conducted. Minimal Criteria of ICG-HGC we used for present study are as followings: At least three relatives with histologically verified gastric cancer; one of them should be a first-degree relative to the other two. At least two successive generations should be affected. In one of the relatives, gastric cancer should be diagnosed under 45 years of age. Suspected HGC fullfills only two of the above three criteria. HNPCC, FAP and Li-Fraumeni syndromes should be excluded. RESULTS: A total of 12 HGCs were identified in this study. In recent 3 years, during the time period 1996 to 1998, the incidence of true and suspected HGC accounted for 6 (0.3%) and 44 probands (2.5%) among 1752 patients (in 1996, 0.4% and 3.2%; in 1997, 0.3% and 1.8%; in 1998, 0.3% and 2.8%) respectively. In contrast, during the time period April, 1999 to June, 1999, the incidence of true and suspected HGC increased up to 3.1% (6 probands) and 11.3% (22 probands), respectively, out of 195 patients (in April, 1999, 0% and 11.7%; in May, 1999, 4% and 14.7%; in June, 1999, 5% and 6.7%). There was no difference in terms of the incidence even if the third criterion of age at diagnosis among Minimal Criteria of ICG-HGC was modified from 'under 45 years of age' to 50. Mean ages of 12 probands (46.3 8.8) were statistically younger than those of control gastric cancer patients (54.2 11.5) retrieved from database of Department of Surgery at Seoul National University College of Medicine. CONCLUSION: In the present study, the incidences of HGC were remarkably altered in accordance with study methods. Retrospective reviews of medical records revealed to be ineffective for this kind of study since their informations were often incomplete and some suspected patients were lost during follow-up. According to the Minimal Criteria of ICG-HGC, the incidence of true and suspected HGC was 3.1% (6 probands) and 11.3% (22 probands), respectively, out of 195 gastric cancer patients. We propose that families who meet the Minimal Criteria of ICG-HGC should be prospectively found in order to determine the exact incidence of HGC in Korean.
