  • 만성 간문맥 고혈압에 동반하는 내장 충혈에 대한 발생 기전을 규명하기 위하여 고양이의 간문맥을 결찰하고 그 경과에 따라 비 -간 교감 신경성 반사 흥분의 변동과 동시에 순환 역동학적 변동을 관찰하였다. 1. 대조 고양이 (Sham 수술군)에서 비동맥을 통하여 capsaicin, bradykinin 및 vasopressin을 주사 하였을 매에는 전신 동맥압의 반사 흥분뿐만 아니라 비정맥압의 상승을 초래하였다. 그러나 심박동수는 변화가 없었다. 동시에 비장(비-비 반사) 및 간장 (비 -간 반사)에서 교감 신경의 만사 흥분을 일으켰다. 2. Capsaicin을 간 표면에 도포하였을 때는 간 신경 흥분 (간-간 반사)과 등시에 승압 반사를 유발시켰다. 3. 문맥 결찰 후에는 비정맥압은 시간 경과에 따라 증가 하였고 이에 동반하여 전신 동맥압은 감소하였다. 그러나 승압반사 항진은 제2일에 현저하게 야기되었고 그후 대조치로 회복되었다. 비-비 또는 비-간 교감 신경 반사 흥분은 제8일에 현저히 감약되었다. 4. 이상의 성적을 종합하면 비장 및 간장에 분포하는 교감 신경 반사 흥분은 동일한 중추 지배에 의하여 조절되고, 간문맥 결찰 후 내장 반사 흥분의 감소는 내장 충혈의 발생과 밀접한 관련이 있을 것으로 사료되었다.

  • Recently we experienced a case of the portal hypertension, extrahepatlc origin in the National Medical Center, Seoul. The case was a male aged 19 who was undergone the elective splenorenal shunt with splenectomy 9 years ago and emergency ligation of the coronary vein because of recurred variceal rupture 6 years later and had recurring esophageal varices with bleeding this time.At the age of 10 he had been occasionally suffering from nasal bleeding and visited to our Pediatric department, when there was encountered for the first time the splenomegaly, esophageal varices in the lower third esophagus on the esophagogram, and stenosis and kinking of the portal vein with rich collateral circulation on the splenoportography without hepatic functional impairment.The elective splenorenal shunt with splenectomy was undergone under the diagnosis of portal hypertension due to congenital anomaly of the portal vein and postoperatlvely no troubles had been obtained until postoperative 1st attack of massive hematemesis due to esophagenl variceal rupture recurred about 6 years later which was confirmed by control esophagogram and it was resulted by stenosis of previous anastomotic site of the splenorenal shunt.Then emergency ligation of the coronary vein was only made for bleeding control and no episodes of hematemesis had been encountered thereafter until April 1972 about 3 years after the 2nd operation, when hematemesis recurred again. In this time, recurring esophageal varices were noted in the lower third esophagus on the control esophagogram and he was employed side to end mesocaval shunt as the final step of portal decompression,and following results were obtained. 1] No postoperatlve troubles as leg edema or pain: Postoperatively leg elevation and elastic bandage on the both legs were employed until discharge. 2] During operation the portal pressure was 300 mm $H_2O$ and immediately lowered to 170 mm $H_2O$ after shunt.

  • A 6-year-old neutered male Poodle with a body weight of 2.7 kg was diagnosed with a congenital extrahepatic portoazygos shunt presented with progressive hepatic encephalopathy. Five days after surgical attenuation, the patient showed post-attenuation neurological signs (PANS) such as generalized tonic-clonic seizure, dull mentation, and tremor. PANS were successfully managed with antiepileptic drugs, but third-space fluid accumulation (ascites and peripheral edema) and phlebectasia were newly identified, suggesting marked portal hypertension (PHT). Telmisartan, spironolactone, carvedilol, and prednisolone were sequentially administered. Three months after surgery, both abnormal clinicopathological values such as anemia and hypoalbuminemia, and clinical signs completely resolved. Herein, we report successful management strategies for PANS and PHT in a dog following surgical attenuation of a congenital portoazygos shunt.

  • To assess the clinical and nutritional status of long-term survivors of biliary atresia, history taking, medical record review, physical examination (height, weight, MAC, TSF), blood tests (LFT, prothrombin time, platelet count, prealbumin, calcium) and liver needle biopsy were performed in 12 patients in whom Kasai procedure were performed more than 10 years ago at Department of Pediatric Surgery in Seoul National University Hospital. None were below the 5th percentile in height and weight. TSF was above the 75th percentile in all patients and showed good subcutaneous fat deposition. MAC was above the 5th percentile in all patients. Serum prealbumin level was abnormal in 2 patients with abnormal liver function and revealed visceral protein malnutrition. Serum calcium level was decreased below normal range in 4 patients with abnormal liver function. One patient had mild ascites. Five patients had abnormal liver function and 7 patients showed clinical manifestation of portal hypertension. Liver needle biopsy was performed in 5 patients and no cirrhotic change was observed. Although some patients who have survived for more than 10 years after Kasai procedure developed protein malnutrition and vitamin deficiencies, growth and development and nutritional status were generally satisfactory. Five patients(42%) showed normal liver function and no portal hypertension. In conclusion, Kasai procedure is satisfactory as a primary treatment in biliary atresia but significant portion of long-term survivors had abnormal liver function and portal hypertension. Continuous and careful follow-up is necessary to determine when liver transplantation may be indicated.

  • Background: Clinically significant portal hypertension (PHT) is considered as a contraindication for hepatectomy according to the guidelines of the European Association for Study of Liver and the American Association for Study of Liver Diseases. However, this issue remains controversial. Here we performed a metaanalysis to evaluate the impact of PHT on the results of hepatectomy for hepatocellular carcinoma (HCC). Methods: Cohort studies evaluating the impact of clinically significant PHT, defined as oesophageal varices and/or splenomegaly associated with thrombocytopenia, on the results of hepatectomy for HCC were identified using a predefined search strategy. Summary risk ratios (RRs) and 95% confidence intervals (95% CIs) for PHT and outcomes after hepatectomy for HCC were calculated. Results: Seven cohort studies which including 574 cases with PHT and 1,354 cases without PHT were considered eligible for inclusion. The meta-analysis showed that, in all patients, pooled RRs of post-operative liver failure, post-operative ascites, peri-operative blood transfusion, operative mortality, 3- and 5-year overall survival associated with PHT were 2.23 (95% CI: 1.48-3.34, P=0.0001), 1.77 (95% CI: 1.19-2.64, P=0.005), 1.23 (95% CI: 1.03-1.49, P=0.03), 2.58 (95% CI: 1.12-5.96, P=0.03), 0.82 (95% CI: 0.75-0.88, P<0.00001) and 0.76 (95% CI: 0.69-0.85, P<0.00001), respectively. In subgroup analysis, similar results were found in Child-Pugh class A patients. Conclusion: This meta-analysis suggests that presence of oesophageal varices and/or splenomegaly associated with thrombocytopenia is associated with higher rates of post-operative complications and poor long-term survival after hepatectomy for HCC.

  • Objective: To investigate the effects of secondary left-sided portal hypertension (LSPH) on the radical operation rate of patients with pancreatic cancer and systemically evaluate the prognosis of patients with LSPH secondary to pancreatic cancer after radical surgery. Materials and Methods: The data of patients with pancreatic cancer who underwent laparotomy over a 15-year period in Department of Hepatobiliary Surgery of Chinese PLA Air Force General Hospital from Jan. 1, 1997, to Jun. 30, 2012 was retrospectively reviewed. Results: A total of 362 patients with pancreatic cancer after laparotomy were selected, including 73 with LSPH and 289 without LSPH. Thirty-five patients with LSPH (47.9%) and 147 without non-LSPH (50.9%) respectively underwent radical operations. No significant difference was found between these two groups regarding the total resection rate and stratified radical resection rate according to different pathological types and cancer locations. The mean and median survival time of patients after radical operation in LSPH group were $13.9{\pm}1.3$ months and 14.8 months, respectively, while those in non-LSPH group were $22.6{\pm}1.4$ months and 18.4 months, respectively(P<0.05). Conclusions: Radical operations for pancreatic cancer and secondary LSPH are safe and effective. Because high-grade malignancy and poor prognosis are closely associated, the decision for radical surgery should be made more meticulously for the patients with pancreatic cancer.

  • Purpose: Limited data exist regarding outcome and morbidity associated with portosystemic shunts in the pediatric transplant population. Our study assesses the outcomes of pediatric patients who underwent a portosystemic shunt procedure, both with and without liver transplantation (LT). Methods: This study retrospectively reviewed the medical records of pediatric patients aged 0-19 years who underwent shunt placement between 2003 and 2017 at a tertiary care center. The analysis included cases of shunt placement with or without LT. Results: A total of 13 pediatric patients were included in the study with median age of 8.8 years. Among the cases, 11 out of 13 (84.6%) underwent splenorenal shunt, 1 (7.7%) underwent a mesocaval shunt, and another 1 (7.7%) underwent a Modified Rex (mesoportal) shunt. Additionally, 5 out of 13 (38.5%) patients had LT, with 4 out of 5 (80.0%) receiving the transplant before shunt placement, and 1 out of 5 (20.0%) receiving it after shunt placement. Gastrointestinal bleeding resulting from portal hypertension was the indication in all cases. A total of 10 complications were reported in 5 patients; the most common complication was anemia in 3 (23.1%) patients. At the most recent follow-up visit, the shunts were functional without encephalopathy, and no deaths were reported. Conclusion: Shunt placement plays a crucial role in the management of patients with portal hypertension. Our study demonstrates favorable long-term outcomes in pediatric patients who underwent shunt placement. Long term shunt outcomes were similar and unremarkable in patients with LT and without LT.

  • Portal hypertensive gastropathy (PHG) is part of a complex syndrome which occurs as a complication of chronic liver disease and portal hypertension. The gastric mucosa in these patients shows typical congestion of ‘mosaic-like’ pattern and vulnerable to various noxious agents such as NSAIDs and ethanol. We previously reported that DA-9601, a quality-controlled extract from Artemisia asiatica, exhibits cytoprotection against various gastritis models. In the present study we investigated the effect of DA-9601 on ethanol-induced gastric damage in PHG rats. Experimental PHG was produced by CBD ligation in SD rats. DA-9601 was orally administered at a dose of 30 mg/kg or 100 mg/kg daily for 2 weeks.
