Background Liver transplantation (LT) is the best treatment in selected patients with hepatocellular carcinoma (HCC). Morphologic criteria alone are not sufficient to predict survival. In this study, we investigated the clinical, biochemical, and pathologic factors affecting survival in patients who underwent LT due to HCC. Methods Between October 2011 and January 2018, 165 of 749 LT for HCC cases performed at the Memorial Atasehir Hospital were evaluated retrospectively. Survival, demographic characteristics and etiology, preoperative alpha-fetoprotein (AFP) level, Model for End-Stage Liver Disease (MELD) score, prognostic staging, and morphologic and histologic properties were evaluated. Results One hundred and thirty-nine cases of 165 were living donor liver transplantation (LDLT). The mean age was 57.7 ± 7.3 years, the mean follow-up period was 27.8 ± 20 months, and 41 patients (24%) died before follow-up. Recurrence of HCC was detected in 23 (14%) cases. Overall survival was 85%, 71%, and 64% for 1, 3, and 5 years, respectively. In terms of 1-, 3-, and 5-year survival within vs beyond Milan criteria was 90%, 80%, and 76% vs 75%, 66%, and 44%, respectively. In the University of California San Francisco criteria, it was 86%, 76%, and 70% vs 76%, 60%, and 30% compared with 1-, 3-, and 5-year survival. While histopathological poor differentiation and AFP elevation affected the course negatively. Good differentiation did not have a significant effect on survival. It was determined that poor differentiation, lymphovascular invasion, and an increased number of nodules significantly affected survival in both within and beyond cases. Conclusion A transplant decision is controversial in patients with HCC with other than previously defined morphologic criteria. In these cases, AFP level and histologic differentiation determine survival. The results were not satisfactory in both high and/or poorly differentiated cases.

- Abstract
Aim: To compare the postprocedural cerebral diffusion-weighted imaging (DWI) findings in cases of carotid stenosis (CS)-related carotid plaques in terms of plaque morphology, degree of stenosis, and the use of a distal protection filter. Moreover, we used DWI to assess the asymptomatic cerebral embolism rates during carotid artery stending (CAS) operations performed for noncalcified versus calcified carotid plaques., Material and Methods: Our study included 99 patients admitted to the Ankara City Hospital Stroke Center in 2022. All of our patients have been evaluated and scheduled for CAS as a result of a decision made by the council. Cases of stenosis of > 50% in symptomatic patients and > 70% in asymptomatic patients were included. The patients were grouped according to their Doppler ultrasonography results. All of the patients underwent DWI within the first 24 hours after the procedure, and then two groups of patients were compared., Results: A statistically significant difference was found between the distributions of the presence of silent micro-infarcts on DWI in terms of plaque characteristics (p < 0.001). In the patients with normal DWI findings, the percentage of calcified plaques was 38.7%, while the percentages of hypoechoic plaques, plaques with low echogenicity, and ulcerated plaques were 91.3%, 85.7%, and 78.8%, respectively. The rates of calcified plaques and ulcerated plaques differed in the group of patients with silent microinfarcts. The rate of silent micro-infarcts was 61.3% in the patients with calcified plaques, 8.7% in those with hypoechoic plaques, 14.3% in those with low-echogenicity plaques, and 21.2% in those with ulcerated plaques., Conclusion: The study found that carotid stents implanted in calcified and ulcerated plaques had a higher correlation with the presence of periprocedural asymptomatic ipsilateral DWI findings than those implanted in hypoechoic plaques and low-echogenicity plaques.

- Abstract
Background: Gallbladder and biliary tract infections are diseases with high mortality rates if they are not treated properly. Microbiological evaluation of perioperatively collected samples both ensures proper treatment of patients and guides empirical treatment due to the determination of microorganism susceptibility., Aims: This study aimed to isolate the microorganisms in bile cultures from patients who underwent cholecystectomy and to determine sensitivity results of these microorganisms., Methods: This study was a multi-center and prospective design, included 360 patients, and was performed between 2019 and 2020. Culture results of bile taken during cholecystectomy were evaluated., Results: Bacterial growth was found in the bile cultures of 84 out of 360 (23.3%) patients. Patients were divided into two groups according to whether they had risk factors for resistant microorganisms or not. While Escherichia coli (n = 11, 13%), Enterococcus spp. (n = 8, 9.5%), and Enterobacter spp. (n = 4, 4.7%) were detected most frequently in patients without risk. Staphylococcus spp. (n = 17, 20.2%), Enterococcus spp. (n = 16, 19%), and E. coli (n = 8, 9.5%) were the most frequently found microorganism at-risk patients. In multivariate analysis, bile culture positivity was found higher in patients who had history of biliary disease (p = 0.004), operation performed concurrently with a cholecystectomy (p = 0.035), and high rate of polymorphonuclear leukocytes (PNL) in total leukocyte count (p = 0.001)., Conclusions: Our study shows that when starting empirical antibiotic treatment for bile ducts, whether patients are at risk for the development of resistant bacterial infection should be evaluated after which antibiotic selection should be made accordingly., (© 2022.

The mean age was 57.7 ± 7.3 years, the mean follow-up period was 27.8 ± 20 months, and 41 patients (24%) died before follow-up. Recurrence of HCC was detected in 23 (14%) cases. Overall survival was 85%, 71%, and 64% for 1, 3, and 5 years, respectively. In terms of 1-, 3-, and 5-year survival within vs beyond Milan criteria was 90%, 80%, and 76% vs 75%, 66%, and 44%, respectively. In the University of California San Francisco criteria, it was 86%, 76%, and 70% vs 76%, 60%, and 30% compared with 1-, 3-, and 5-year survival. While histopathological poor differentiation and AFP elevation affected the course negatively. Good differentiation did not have a significant effect on survival. It was determined that poor differentiation, lymphovascular invasion, and an increased number of nodules significantly affected survival in both within and beyond cases., Conclusion: A transplant decision is controversial in patients with HCC with other than previously defined morphologic criteria. In these cases, AFP level and histologic differentiation determine survival. The results were not satisfactory in both high and/or poorly differentiated cases., (Copyright © 2019 Elsevier Inc.

- Abstract
Liver transplantation (LT) has become a favorable therapeutic option for patients with end-stage liver diseases. Gilbert's syndrome (GS) is a benign condition characterized by intermittent mild jaundice due to unconjugated hyperbilirubinemia. It is not obvious whether living-donor liver transplantation (LDLT) from a donor with GS could result in a normal outcome for both the recipient and the donor. We aimed to determine whether right lobe hepatectomy is a safe procedure for living donors with GS and LT recipients. Between September 2011 and March 2015, 305 LDLT procedures using right lobe grafts were performed at Atasehir Memorial Hospital, Istanbul, Turkey. Nineteen of 305 LT candidates who had been diagnosed with GS were included in the current study. After a 12-h overnight fast, total and indirect bilirubin levels of donors and recipients were measured. The median follow-up after transplant was 16 months (range 3-36 months). The median age of donors was 25 (range 20-55 yr). Four donors (21%) were female, and 15 donors (89%) were male. The median age of donors was 51 (range 23-68 yr). Eleven recipients (57%) were female, and 8 (43%) were male. The median preoperative total bilirubin level of donors was 1.69 mg/dL (range 1.26-2.43 mg/dL) (normal range <1.2 mg/dL). The median total bilirubin level of donors on postoperative day 7 was 1.04 mg/dL (range 0.71-3.23 mg/dL). As our study has included a large number of donors with GS, it produced reliable evidence that right lobe hepatectomy is a safe procedure for living donors with GS and LT recipients., (© 2015 John Wiley & Sons A/S.

- Abstract
Aim: Intestinal anastomoses are always risky in patients who develop intra-abdominal sepsis. In this study, the effects of combined glutamine and growth hormone (GH) on healing of intestinal anastomosis following intestinal repair in the rat intra-abdominal sepsis was induced., Material and Methods: Forty Sprague Dawley Albino rats at 10 weeks weighing between 180 and 240 g were included in the study. All the animals were divided into five groups comprising eight rats each. In the control group, no treatment was given in addition to the routine oral nutrition before and after surgery. In the other groups, following surgery, oral glutamine was given at a dose of 1 mg/kg/d in the glutamine group, subcutaneous GH was given at a dose of 1 mg/kg/d in the GH group, and combined glutamine and GH were administered at the same doses in the glutamine + GH group. In rats, a clinical model mimicking intestinal fistula was generated and fistula repair was performed, and the bursting pressure of the repair area and tissue hydroxyproline level of the repair area were calculated., Results: Compared with the control group, glutamine, GH, and combined groups displayed significantly higher mean bursting pressures and tissue hydroxyproline levels., Conclusion: In order to decrease the risks originating from impaired mechanisms due to intra-abdominal sepsis, and to make anastomosis safer, combined use of glutamine and GH increases the bursting pressure of anastomosis. While the use of either of these two substances alone is effective, combined use makes this effect more prominent., (Copyright © 2013 Elsevier Inc. All rights reserved.)

- Abstract
Objective: Penetrating colonic injuries are amongst the most discussed intra-abdominal injuries because of the complexity of their management and the severe complications. Penetrating colonic injuries can be managed by either primary repair or diversion. There is a debate over which procedure has to be used under which circumstances. In this retrospective study we analyzed our experience to contribute to the answer., Patients and Methods: The records of patients with penetrating colonic injury between January 1995 and December 2006 at the General Surgery Department of Atatürk University School of Medicine, were reviewed retrospectively., Results: One hundred and forty-one patients were included in the study. Ten patients did not need any surgical treatment. Seventy-nine patients (56%) were treated without formation of a stoma and fifty-two patients (36.8%) with formation of a stoma. The overall complication rate was 50.3% (71 patients). The rate of septic complications was 33.3%., Conclusion: There is an ongoing debate whether formation of a stoma is indicated in penetrating colonic injury or not. Our clinical experience showed that severe faecal contamination, shock at presentation, and high CIS grades are associated with increased postoperative complications and mortality. Therefore the treatment of penetrating colonic injury in the presence of these risk factors should be stoma formation rather than primary repair.

- Abstract
Background: Human alveolar echinococcosis (AE) is a potentially fatal, chronically progressive hepatic infestation that is characterized by a long asymptomatic period in which an invasive tumor-like lesion develops. Several studies have suggested that genetic susceptibility to AE may be linked to HLA class II alleles. We investigated the association between AE and antigen HLA-A, B, C, DR and DQ profiles of patients with hepatic AE (HAE) in the eastern part of Turkey., Methods: This case-controlled study was performed on 44 unrelated patients with HAE and 76 control subjects. The diagnosis was supported by clinical, radiological, and histopathological evidence. The association of class I and class II HLA antigens was examined in the patients with HAE and control subjects., Results: There was an increase in the antigen frequencies of HLA-DRB1*15, HLA-DQB1*02, 06, 07 in the HAE patientscompared with those in the control group (P < 0.05, P < 0.001, P < 0.01, P < 0.05, respectively). HLA-DQB1*02, 06, 07 were more frequent in patients with stages III and IV who were classified according to the PNM staging system., Conclusions: The present study indicates that susceptibility to HAE in the Turkish population is essentially HLA class II and poorly class I mediated, with HLA-26, and DRB1*015, DQB1* 02, 06, 07 with more allele distribution in the patient group. Our results are not similar to those of other studies, but contribute to the discussions on the association of HLA class I and class II alleles with AE.
