| 1 | Intraoperative radiofrequency ablation with or without tumorectomy for hepatocellular carcinoma in locations difficult for a percutaneous approach显示文摘BACKGROUND:Although hepatic resection is widely accepted as a proper modality for treating hepatocellular carcinoma(HCC),a majority of patients are unable to undergo surgical resection due to various tumor and patient factors.Radiofrequency ablation(RFA)has mostly been used as a therapeutic alternative to resection for treating HCC.The objective of this study was to evaluate the results of intraoperative RFA for HCCs in locations difficult for a percutaneous approach.METHODS:Eight patients(male,seven;age,49-67 years) with 8 HCCs in difficult locations were treated by intraoperative RFA.Six of the patients had local tumor progression after initial transarterial chemoembolization or ultrasound(US)guided percutaneous RFA.The locations of the tumors were hepatic dome in six patients,posterior subcapsule in one,and caudate lobe in one.The tumor size was 2.0 to 6.4 cm(mean,3.9 cm).Intraoperative RFA was performed at the tumor itself and an anticipated resection line under US guidance with 3 cm monopolar single or clustered internally cooled electrodes.Tumor resection was performed in six patients.One month later,treatment response was assessed by contrast material-enhanced computed tomography(CT).CT studies were performed every 2 or 3 months after RFA.RESULTS:RFA was technically successful in all tumors,and the contrast-enhanced CT images acquired one month later showed complete disappearance of tumor enhancement.One pneumothorax occurred.After a median follow-up of 18 months(range,6-30 months),no tumors showed local progression.During the follow-up period,four new recurrent tumors were observed in three patients.Four patients were alive at the time of this report and the other four died of hepatorenal syndrome,liver failure,and progression of new recurrent tumors.CONCLUSION:Intraoperative RFA with tumor resection can be an alterative treatment option for HCC in locations difficult for a percutaneous approach. | Hyung Ook Kim Seung Kwon Kim Byung Ho Son Chang Hak Yoo Hyun Pyo Hong Yong Kyun Cho Byung Ik Kim | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，6： | 9 |
| 2 | Quality of survival in patients treated for malignant biliary obstruction caused by unresectable pancreatic head cancer: surgical versus non-surgical palliation显示文摘BACKGROUND:Appropriate palliation for unresectable pancreatic head cancer is most important.This study was undertaken to compare the survival of patients with biliary obstruction caused by unresectable pancreatic head cancer after surgical and non-surgical palliation. METHODS:We retrospectively reviewed 69 patients who underwent palliative treatment for unresectable pancreatic head cancer.Fifty-two patients with locally advanced disease (local vascular invasion)and 17 with distant metastatic disease were included.The patients were divided into two groups,surgical and non-surgical palliation. RESULTS:Thirty-eight patients underwent biliary bypass surgery and 31 had percutaneous transhepatic biliary drainage(PTBD).There was no significant difference in the early complications,successful biliary drainage, recurrent jaundice,and 30-day mortality between surgical palliation and PTBD.However,in 52 patients whose tumor was unresectable secondary to local vascular invasion,the rate of recurrent jaundice after successful surgical biliary palliation was lower than that in patients who had non- surgical palliation(P<0.05).The patients who underwent surgical palliation had a longer hospital-free survival rate(P<0.001),although they had a longer postoperative hospital stay(P=0.004)during the first admission period.CONCLUSIONS:In patients with preoperative evaluations showing potentially resectable tumors and/or no metastatic lesions,surgical exploration should be performed.Thus,in patients who have unresectable cancer or limited metastatic disease on exploration,surgical palliation should be performed for longer survival and better quality of survival. | Hyung Ook Kim Sang Il Hwang Hungdai Kim Jun Ho Shin | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，6： | 8 |
| 3 | Non-surgical treatment of post-surgical bile duct injury: Clinical implications and outcomes显示文摘AIM:To investigate the prognostic factors determining the success rate of non-surgical treatment in the management of post-operative bile duct injuries(BDIs).METHODS:The study patients were enrolled from the pancreatobiliary units of a tertiary teaching hospital for the treatment of BDIs after hepatobiliary tract surgeries,excluding operations for liver transplantation andmalignancies,from January 1999 to August 2010.A total of 5167 patients underwent operations,and 77patients had BDIs following surgery.The primary end point was the treatment success rate according to different types of BDIs sustained using endoscopic or percutaneous hepatic approaches.The type of BDI was defined using one of the following diagnostic tools:endoscopic retrograde cholangiography,percutaneous transhepatic cholangiography,computed tomography scan,and magnetic resonance cholangiography.Patients with a final diagnosis of BDI underwent endoscopic and/or percutaneous interventions for the treatment of bile leak and/or stricture if clinically indicated.Patient consent was obtained,and study approval was granted by the Institutional Review Board in accordance with the legal regulations of the Human Clinical Research Center at the Seoul National University Hospital in Seoul,South Korea.RESULTS:A total of 77 patients were enrolled in the study.They were divided into three groups according to type of BDI.Among them,55 patients(71%)underwent cholecystectomy.Thirty-six patients(47%)had bile leak only(type 1),31 patients had biliary stricture only(type 2),and 10 patients had both bile leak and biliary stricture(type 3).Their initial treatment modalities were non-surgical.The success rate of non-surgical treatment in each group was as follows:BDI type 1:94%;type 2:71%;and type 3:30%.Clinical parameters such as demographic factors,primary disease,operation method,type of operation,non-surgical treatment modalities,endoscopic procedure steps,type of BDI,time to diagnosis and treatment duration were evaluated to evaluate the prognostic factors affecting the success rate.The type of BDI was a statistically significant prognostic factor in determining the success rate of non-surgical treatment.In addition,a shorter time to diagnosis of BDI after the operation correlated significantly with higher success rates in the treatment of type 1 BDIs.CONCLUSION:Endoscopic or percutaneous hepatic approaches can be used as an initial treatment in type1 and 2 BDIs.However,surgical intervention is a treatment of choice in type 3 BDI. | Young Ook Eum Joo Kyung Park Jaeyoung Chun Sang-Hyub Lee Ji Kon Ryu Yong-Tae Kim Yong-Bum Yoon Chang Jin Yoon Ho-Seong Han Jin-Hyeok Hwang | 2014 | World Journal of Gastroenterology2014，20，22： | 7 |
| 4 | Outcome of laparoscopic cholecystectomy is not influenced by chronological age in the elderly显示文摘AIM:To evaluate the outcome of laparoscopic cholecystectomy(LC)in patients aged 80 years and older. METHODS:A total of 353 patients aged 65 to 79 years(group 1)and 35 patients aged 80 years and older(group 2)underwent LC.Patients were further classified into two other groups:those with uncomplicated gallbladder disease(group A)or those with complicated gallbladder disease(group B). RESULTS:There were no significant differences between the age groups(groups 1 and 2)with respect to clinical characteristics such as age,gender,comorbid disease,or disease presentation.Mean operative time,conversion rate,and the incidence of major postoperative complications were similar in groups 1 and 2.However,the percentage of high-risk patients was significantly higher in group 2 than in group 1 (20.0%vs 5.7%,P<0.01).Group A comprised 322 patients with a mean age of 71.0±5.3 years,and group B comprised 51 patients with a mean age of 69.9±4.8 years.In group B,mean operative time (78.4±49.3 min vs 58.3±35.8 min,P<0.01),mean postoperative hospital stay(7.9±6.5 d vs 5.0±3.7 d, P<0.01),and the incidence of major postoperative complications(9.8%vs 3.1%,P<0.05)were significantly greater than in group A.The conversion rate tended to be higher in group B,but this difference was not significant. CONCLUSION:Perioperative outcomes in elderly patients who underwent LC seem to be influenced by the severity of gallbladder disease,and not by chronologic age.In octogenarians,LC should be performed at an earlier,uncomplicated stage of the disease whenever possible to improve perioperative outcomes. | Hyung Ook Kim Jung Won Yun Jun Ho Shin Sang Il Hwang Yong Kyun Cho Byung Ho Son Chang Hak Yoo Yong Lai Park Hungdai Kim | 2009 | World Journal of Gastroenterology2009，15，6： | 5 |

| 6 | Surgical palliation of unresectable pancreatic head cancer in elderly patients显示文摘AIM: To determine if surgical biliary bypass would provide improved quality of residual life and safe palliation in elderly patients with unresectable pancreatic head cancer. METHODS: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (Group A). These patients were compared with 19 patients under 65 years of age who were managed with surgical biliary bypass (Group B). In addition, the results for group A were compared with those obtained from 17 patients, 65 years of age or older (Group C), who received percutaneous transhepatic biliary drainage to evaluate the quality of residual life. RESULTS: Five patients (26.0%) in Group A had complications, including one intraabdominal abscess, one pulmonary atelectasis, and three wound infections. One death (5.3%) occurred on postoperative day 3. With respect to morbidity, mortality, and postoperative hospitalization, no statistically significant difference was noted between Groups A and B. The number of readmissions and the rate of recurrent jaundice were lower in Group A than in Group C, to a statistically significant degree (P = 0.019, P = 0.029, respectively). The median hospital-free survival period and themedian overall survival were also signifi cantly longer in Group A (P = 0.001 and P < 0.001, respectively). CONCLUSION: Surgical palliation does not increase the morbidity or mortality rates, but it does increase the survival rate and improve the quality of life in elderly patients with unresectable pancreatic head cancer. | Sang Il Hwang Hyung Ook Kim Byung Ho Son Chang Hak Yoo Hungdai Kim Jun Ho Shin | 2009 | World Journal of Gastroenterology2009，15，8： | 4 |
| 7 | Functional roles of taurine,L-theanine,Lcitrulline,and betaine during heat stress in poultry显示文摘Heat stress(HS)is an important environmental stress factor affecting poultry production on a global scale.With the rise in ambient temperature and increasing effects of global warming,it becomes pertinent to understand the effects of HS on poultry production and the strategies that can be adopted to mitigate its detrimental impacts on the performance,health,welfare,immunity,and survival of birds.Amino acids(AAs)have been increasingly adopted as nutritional modifiers in animals to ameliorate the adverse effects of HS.They are essential for protein synthesis,growth,maintenance,reproduction,immunity,stress response,and whole-body homeostasis.However,HS tends to adversely affect the availability,transport,absorption,and utilization of these AAs.Studies have investigated the provision of these AAs to poultry during HS conditions,and variable findings have been reported.Taurine,L-theanine,and L-citrulline are non-essential amino acids that are increasingly gaining attention as nutritional supplements in HS animals.Similarly,betaine is an amino acid derivative that possesses favorable biological properties which contributes to its role as a functional additive during HS.Of particular note,taurine is negligible in plants,while betaine,L-theanine,and L-citrulline can be found in selected plants.These nutrients are barely found in feed ingredients,but their supply has been shown to elicit important physiological roles including anti-stress effects,anti-oxidative,anti-inflammatory,gut promoting,and immunomodulatory functions.The present review provides information on the use of these nutritionally and physiologically beneficial nutrients as functional additives to poultry diets during HS conditions.Presently,although several studies have reported on the positive effects of these additives in human and murine studies,however,there is limited information regarding their utilization during heat stress in poultry nutrition.Therefore,this review aims to expound on the functional properties of these nutrients,their potentials for HS alleviation,and to stimulate further researches on their biological roles in poultry nutrition. | Victoria Anthony Uyanga Emmanuel OOke Felix Kwame Amevor Jingpeng Zhao Xiaojuan Wang Hongchao Jiao Okanlawon MOnagbesan Hai Lin | 2022 | Journal of Animal Science and Biotechnology2022，13，4： | 3 |
