| 1 | The incidence of Mirizzi syndrome in patients undergoing endoscopic retrograde cholangiopancreatography显示文摘BACKGROUND:Mirizzi syndrome is a rare complication of cholelithiasis,characterized by the narrowing of the common hepatic duct as a result of mechanical compression and/or inflammation due to biliary calculus impacted in the infundibula of the gallbladder or in the cystic duct.In this study,we aimed to describe the clinical presentations,investigations,operative details,and complications of seven patients who underwent endoscopic retrograde cholangiopancreatography and were finally diagnosed with Mirizzi syndrome in our center. METHOD:We performed a retrospective analysis of the records of 7 patients with Mirizzi syndrome who underwent endoscopic retrograde cholangiopancreatography. RESULTS:The incidence of Mirizzi syndrome was 1.07% of 656 patients given endoscopic retrograde cholangiopan- creatography.Ultrasonography was able to diagnose one case.Endoscopic retrograde cholangiopancreatography suggested the diagnosis in five cases and helped further in the management of these patients.Four patients had cholecystectomy and T-tube placement,and two had cholecystectomy and choledochoduodenostomy.One patient with typeⅠMirizzi syndrome according to the Csendes classification successfully underwent laparoscopic cholecystectomy. CONCLUSIONS:In the study,the incidence of Mirizzi syndrome was 1.07%of patients who underwent endoscopic retrograde cholangiopancreatography. Preoperative diagnosis of Mirizzi syndrome by endoscopicretrograde cholangiopancreatography is important to prevent complications. | Nadir Yonetci Ufuk Kutluana Mustafa Yilmaz Ugur Sungurtekin Koray Tekin | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，5： | 30 |
| 2 | Total thyroidectomy is safer with identification of recurrent laryngeal nerve显示文摘Objective:To investigate the effect of recurrent laryngeal nerve(RLN)identification on the complications after total thyroidectomy and lobectomy.Methods:Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively.Patients were divided into two groups:RLN identified (Group A)or not(Group B).The two groups were compared for RLN injury and hypocalcaemia.Results:The numbers of patients and nerves at risk were 71 and 129 in Group A,and 63 and 121 in Group B,respectively.RLN injury in Group A(0)was sig- nificantly lower than that in Group B(57.9%)patients,75.8%nerves)for the numbers of patients(P=0.016)and nerves at risk (P=0.006).Temporary hypocalcaemia was significantly higher in Group A than in Group B(1424.1%vs 610.3%,P=0.049). Permanent complications in Group B were significantly higher than those in Group A(1320.6%vs 45.6%,P=0.009).Con- clusion:RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy. | Hakan CANBAZ Musa DIRLIK Tahsin COLAK Koray OCAL Tamer AKCA Oner BILGIN Bahar TASDELEN Suha AYDIN | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008，9，6： | 20 |
| 3 | Effect of autotransfusion system on tumor recurrence and survival in hepatocellular carcinoma patients显示文摘AIM:To investigate the therapeutic efficacy and safety of continuous autotransfusion system(CATS) during liver transplantation of hepatocellular carcinoma patients.METHODS:Eighty-three hepatocellular carcinoma(HCC) patients who underwent liver transplantation with intraoperative CATS(n = 24,CATS group) and without(n = 59,non-CATS group) between April 2006 and November 2011 at the Liver Transplant Institute of Inonu University were analyzed retrospectively.Postoperative HCC recurrence was monitored by measuring alpha-fetoprotein(AFP) levels at 3-mo intervals and performing imaging analysis by thoracoabdominal multidetector computed tomography at 6-month intervals.Inter-group differences in recurrence and correlations between demographic,clinical,and pathological data were assessed by ANOVA and χ 2 tests.Overall and disease-free survivals were calculated by the univariate Kaplan-Meier method.RESULTS:Of the 83 liver transplanted HCC patients,89.2% were male and the overall mean age was 51.3 ± 8.9 years(range:18-69 years).The CATS and nonCATS groups showed no statistically significant differences in age,sex ratio,body mass index,underlying disease,donor type,graft-to-recipient weight ratio,Child-Pugh and Model for End-Stage Liver Disease scores,number of tumors,tumor size,AFP level,Milan and University of California San Francisco selection criteria,tumor differentiation,macrovascular invasion,median hospital stay,recurrence rate,recurrence site,or mortality rate.The mean follow-up time of the nonCATS group was 17.9 ± 12.8 mo,during which systemic metastasis and/or locoregional recurrence developed in 25.4% of the patients.The mean follow-up time for the CATS group was 25.8 ± 15.1 mo,during which systemic metastasis and/or locoregional recurrence was detected in 29.2% of the patients.There was no significant difference between the CATS and non-CATS groups in recurrence rate or site.Additionally,no significant differences existed between the groups in overall or disease-free survival.CONCLUSION:CATS is a safe procedure and may decrease the risk of tumor recurrence in HCC patients. | Sami Akbulut Cuneyt Kayaalp Mehmet Yilmaz Volkan Ince Dincer Ozgor Koray Karabulut Cengiz Eris Huseyin Ilksen Toprak Cemalettin Aydin Sezai Yilmaz | 2013 | World Journal of Gastroenterology2013，19，10： | 17 |
| 4 | Intrahepatic biliary cystic neoplasms:Surgical results of 9 patients and literature review显示文摘AIM: To investigate the eligible management of the cystic neplasms of the liver. METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution. RESULTS: All patients were female with a median (range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients. Four patients had undergone previous laparotomy (with other diagnoses) which resulted in incomplete surgery or recurrences. Liver resection (n = 6) or enucleation (n = 3) was performed. The final diagnosis was intrahepaticbiliary cystadenoma in 8 patients and cystadenocarcinoma in 1 patient. All symptoms resolved after surgery. There has been no recurrence during a median (range) 31 (7-72) mo of follow up. CONCLUSION: In spite of the improvement in imaging modalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal (liver resection or enucleation) of these lesions yields satisfying long-term results. | Ali Emre Kür■at Rahmi Serin Ilgin zden Yaman Tekant Orhan Bilge Ayd■n Alper Mine Güllüoglu Koray Güven | 2011 | World Journal of Gastroenterology2011，17，3： | 15 |
| 5 | Wheat straw pretreatment with KOH for enhancing biomethane production and fertilizer value in anaerobic digestion显示文摘Wheat straw biodegradability during anaerobic digestion was improved by treatment with potassium hydroxide(KOH)to decrease digestion time and enhance biomethane production and fertility value.KOH concentrations of1%(K1),3%(K2),6%(K3)and 9%(K4)were tested for wheat straw pretreatment at ambient temperature with a C:N ratio of 25:1.86% of total solids(TS),89% of volatile solids(VS)and 22% of lignocellulose,cellulose and hemicellulose(LCH)(22%)were decomposed effectively with the wheat straw pretreated by 6% KOH.Enhanced biogas production and cumulative biomethane yield of 258 ml·(g VS)^(-1)were obtained increased by 45% and 41%respectively,compared with untreated wheat straw.Pretreated wheat straw digestion also yielded a digestate with higher fertilizer values potassium(138%),calcium(22%)and magnesium(16%).These results show that TS,VS and LCH can be effectively removed from wheat straw pretreated with KOH,improving biodegradability biomethane production and fertilizer value. | Muhammad Jaffar Yunzhi Pang Hairong Yuan Dexun Zou Yanping Liu Baoning Zhu Rashid Mustafa Korai Xiujin Li | 2016 | Chinese Journal of Chemical Engineering2016，24，3： | 11 |
| 6 | Unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis显示文摘AIM: To investigate the prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis. METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases. | Mehmet Yilmaz Sami Akbulut Koray Kutluturk Nurhan Sahin Ebru Arabaci Cengiz Ara Sezai Yilmaz | 2013 | World Journal of Gastroenterology2013，19，25： | 9 |
| 7 | Pancreatic hyperechogenicity on endoscopic ultrasound examination显示文摘There is an ongoing discussion on how to diagnose a hyperechogenic pancreas and what is the clinical significance of diffusely hyperechogenic pancreas. Computerized tomography and magnetic resonance imaging are the more appropriate methods to diagnose pancreatic hyperechogenicity when compared with transcutaneous or endoscopic ultrasound examination. More importantly, pancreatic hyperechogenicity may not be a certain indicator of pancreatic fat infiltration. Even if it is true, we do not know the clinical significances of pancreatic fat accumulation. Some suggested that excess fat in the pancreas is associated with chronic pancreatitis. However, several histological studies on human alcoholic chronic pancreatitis did not prove the presence of fatty pancreas in such cases. Thus, except for aging, it is very rare to have truly steatotic pancreas in the absence of certain human diseases. | Yucel Ustundag Guray Ceylan Koray Hekimoglu | 2011 | World Journal of Gastroenterology2011，17，15： | 5 |
| 8 | Hepatic artery reconstruction technique in liver transplantation:experience with 3,000 cases显示文摘Hepatic artery reconstruction(HAR)is the most valuable step in correcting graft and recipient survival after liver transplantation(LT).Hepatic artery thrombosis(HAT)in immediate postoperative period may lead to fatal complications.Hepatic allograft is partial in a living donor liver transplantation(LDLT),and HAR is technically much more difficult than deceased donor liver transplantation(DDLT).The likelihood of HAT in LDLT is higher due to the narrower diameters of arterial vessels. | Sami Akbulut Koray Kutluturk Sezai Yilmaz | 2021 | Hepatobiliary Surgery and Nutrition2021，10，2： | 4 |
| 9 | 比较标准超声波测量仪和新型光学生物测量仪计算人工晶状体屈光度的准确性(英文)显示文摘目的:比较超乳手术时应用新型光学生物测量仪和标准超声波测量仪计算人工晶状体的屈光度及屈光结果。方法:前瞻性研究。研究包含37例37眼白内障患者接受白内障超声乳化联合人工晶状体植入术。同一测量人员分别使用新型光学生物测量仪(Aladdin)与标准超声波测量仪(Sonomed AB 5500)对白内障患者进行检测。通过这两种设备记录生物测定参数,包括眼轴长度、角膜曲率、前房深度及人工晶状体屈光度数。分析术后实际屈光不正与两台设备根据SRK/T公式计算的误差,比较两台设备检查结果的平均估计误差(EE)、平均绝对估计误差(AEE)及生物测定参数。结果:Aladdin测量仪(23.45±0.73 mm)较超声波测量仪(23.2±0.75 mm)检测出的眼轴显著较长(P=0.01)。Aladdin测量仪的EE与AEE均明显小于超声波测量仪(P=0.0006与0.03)。应用Aladdin测量的大多数眼与目标屈光度相差在±0.5(67%)及±1.00(97%)以内。结论:Aladdin光学生物测量仪较超声波测量仪更精确,屈光结果更准确。 | Faruk Kaya Ibrahim Kocak Ali Aydin Hakan Baybora Koray Karadayi | 2016 | 国际眼科杂志2016，16，5： | 3 |
| 10 | Laparoscopic right-sided colonic resection with transluminal colonoscopic specimen extraction显示文摘AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery. METHODS: The diagnoses of our patients were Crohn's disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance. The stump of the colon was opened with laparoscopic scissors. A snare of colonoscope was released and the intraperitoneal complete free colonic specimen was grasped. Specimen was moved in to the colon with the help of the laparoscopic graspers and pulled gently through the large bowel and extracted through the anus. The open end of the colon was closed again and the ileal limb and the colon were anastomosed intracorporeally with a 60-mm laparoscopic stapler. The common enterotomy orifice was closed in two layers with a running intracorporeal suture.RESULTS: There were three patients with laparoscopic right-sided colonic resections and their specimens were intended to remove through the remnant colon by colonoscopy but the procedure failed in one patient(adenocarcinoma) due to a bulky mass and the specimen extraction was converted to transvaginal route. All the patients had prior abdominal surgeries and had related adhesions. The operating times were 210, 300 and 500 min. The lengths of the specimenswere 13, 17 and 27 cm. In our cases, there were no superficial or deep surgical site infections or any other complications. The patients were discharged uneventfully within 4-5 d and they were asymptomatic after a mean 7.6 mo follow-up(ranged 4-12). As far as we know, there were only 12 cases reported yet on transcolonic extraction of the proximal colonic specimens by colonoscopic assistance after laparoscopic resections. With our cases, success rate of the overall experience in the literature was 80%(12/15) in selected cases. CONCLUSION: Transcolonic specimen extraction for right-sided colonic resection is feasible in selected patients. Both natural orifice surgery and intracorporeal anastomosis avoids mini-laparotomy for specimen extraction or anastomosis. | Cuneyt Kayaalp Koray Kutluturk Mehmet Ali Yagci Mustafa Ates | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，12： | 3 |
| 11 | Renoportal anastomosis in living donor liver transplantation with prior proximal splenorenal shunt显示文摘For transplant surgeons, end-stage liver disease with portal venous thrombosis and a previous splenorenal shunt(SRS) is a significant challenge during liver transplantation. Thrombosis of the portal vein can be corrected by surgical interventions, such as portal venous thrombectomy or surgical removal of the thrombosed portal vein. Even also placement of a graft between the mesenteric vein and the graft portal vein can be performed. If these maneuvers fail, a renoportal anastomosis(RPA) can be performed to achieve adequate graft inflow. A 51-year-old male patient who had a history of proximal SRS and splenectomy underwent living donor liver transplantation(LDLT) due to cryptogenic cirrhosis. LDLT was performed with RPA using a cadaveric iliac vein graft. The early postoperative course of the patient was completely uneventful and he was discharged 20 d after transplantation. To the best of our knowledge, this was the first patient to receive LDLT with RPA after surgical proximal SRS and splenectomy. | Fatih Ozdemir Koray Kutluturk Bora Barut Perviz Abbasov Ramazan Kutlu Cuneyt Kayaalp Sezai Y?lmaz | 2017 | World Journal of Transplantation2017，7，1： | 2 |
