Öğe Can Patients Who Develop Cerebral Death in Fulminant Liver Failure Despite Liver Transplantation Be Previously Forseen?(Elsevier Science Inc, 2017) Sarici, K. B.; Karakas, S.; Otan, E.; Ince, V.; Koc, C.; Koc, S.; Bayraktar, H.Background. The outcome of medical treatment is worse in fulminant liver failure (FLF) developing on acute or chronic ground. Recently, liver transplantations with the use of living and cadaveric donors have been performed in these diseases and good results obtained. In this study, we aimed to present the factors affecting the recovery of cerebral functions after liver transplantation in hepatic encephalopathy (HE) developing in FLF, to identify irreversible patient groups and to prevent unnecessary liver transplantation. Methods. In Inonu University's Liver Transplant Institute, 69 patients who made an emergency notice to the National Coordination Center for liver transplantation owing to FLF from January 2012 to December 2015 were included in the study. Patients were divided into 2 groups. Group 1 consisted of 52 patients who underwent liver transplantation and recovered normal brain function, and group 2 had 17 patients who underwent liver transplantation and did not recover normal brain function and had cerebral death. All patients were evaluated before surgery for clinical encephalopathy stage, light reflex, and convulsions. Groups were compared and assessed according to age (>40, 10-40 and <10 years), body mass index, etiologic factor, preoperative laboratory values, transplantation type, mortality, and encephalopathy level. Multivariate analysis was done for specific parameters. Results. Prothrombin time (PT), international normalized ratio (INR), and total bilirubin values were significantly different between the groups. There was no significant difference between the groups regarding ammonia and lactate levels. There was a statistically significant difference between the groups regarding sodium and potassium levels from serum electrolytes. However, the averages of both groups were within normal limits. pH and total bilirubin levels were meaningful for multivariate analysis. Conclusions. HE reversibility, mortality, and morbidity are important in patients with HE who undergo liver transplantation. Therefore, West Haven clinical staging and serum INR, PT, and total bilirubin level may be helpful in predicting the reversibility of FLF patients with HE before liver transplantation. It was determined that West Haven encephalopathy grading is important in determining the reversibility of HE after transplantation in FLF; especially the probability of reversibility of stage 4 HE decreases significantly. High PT and INR levels, hyperbilirubinemia, and serum sodium and potassium concentrations were risk factors for the reversibility of HE in this study.Öğe Coexistence of Right Obturator, Lacunar, Direct Inguinal, Bilateral Indirect Inguinal, and Bilateral Femoral Hernias and Treatment with Totally Extraperitoneal Laparoscopy(Springer India, 2021) Ates, M.; Ciftci, F.; Sahin, E.; Sarici, K. B.The majority of groin hernias are treated according to the findings of the physical examination, but patients may also have occult hernias. With the use of laparoscopy, hernias that were not noticed during the initial examination or even in radiological images are increasingly being detected intraoperatively. Here, we present the case of a 62-year-old gentleman diagnosed with seven different types of occult and non-occult bilateral inguinal hernias that were treated with laparoscopic totally extraperitoneal herniorrhaphy. A major advantage of this method is that it allows the simultaneous diagnosis and treatment of occult and rare inguinal hernias.Öğe Effects of Apocynin on Liver Ischemia-Reperfusion Injury in Rats(Elsevier Science Inc, 2019) Yucel, A.; Aydogan, M. S.; Ucar, M.; Sarici, K. B.; Karaaslan, M. G.Objective. Ischemia-reperfusion (IR) injury is associated with various clinical conditions, such as myocardial infarction, shock, and surgery under vascular occlusion. We aimed to investigate the protective and therapeutic effects of apocynin (AP) on liver injury induced by IR in an in vivo rat model. Methods. Thirty-two rats were randomly divided into 4 experimental groups with n = 8 in each group: sham, IR, AP, and IR + AP. AP (20 mg/kg) was intraperitoneally administered to rats in the AP and IR + AP groups for 30 minutes before 60 minutes of ischemia and followed by 60 minutes of reperfusion. All rats were killed on the same day to evaluate tissue levels of oxidants and antioxidants (catalase, malondialdehyde, myeloperoxidase, superoxidedismutase (SOD), and total glutathione). Results. IR decreased SOD levels in IR group when compared with the sham group. AP supplementation to IR group significantly ameliorated SOD levels (P < .05). Also, IR caused elevation of myeloperoxidase production when compared with the sham group, whereas AP treatment prevented these hazardous effects (P < .05). However, plasma total glutathione, catalase, and malondialdehyde levels did not differ between the AP + IR and the IR rats. Conclusion. The main finding of the present study was that AP may be protective against liver IR injury. Our results suggested that AP pretreatment suppressed oxidative stress and increased antioxidant levels in an rat model of liver IR.Öğe The incidence and risk factors for persistent unconsciousness following liver transplantation for acute liver failure(Lippincott Williams & Wilkins, 2019) Sarici, K. B.; Otan, E.; Ince, V; Sahin, T. T.; Karakas, S.; Saglam, K.; Aydin, C.[Abstract Not Available]Öğe Incidental Appendectomy in Donors Undergoing Hepatectomy for Living-Donor Liver Transplantation(Elsevier Science Inc, 2012) Yilmaz, M.; Olmez, A.; Piskin, T.; Unal, B.; Ersan, V.; Sarici, K. B.; Dirican, A.Background. The aim of this study was to investigate the morbidity associated with appendectomy in living liver donors undergoing hepatectomy. Methods. The medical records of 338 donors who underwent hepatectomies for living-donor liver transplantation between 2008 and 2010 were reviewed retrospectively. The patients were divided into 2 groups on the basis of appendectomy: patients in group A (n = 126) received incidental appendectomies in conjunction with donor hepatectomy, and those in group B (n = 212) underwent hepatectomy alone. Results. No significant difference in age, gender, or body mass index was found between groups. The wound infection rate (P = .037) and length of hospital stay (P = .0038) were higher in group A than in group B. Intraoperative findings in 126 donors in group A were subserosal (n = 4), retrocecal (n = 6), or hard nodular (n = 11) appendix; hyperemic appendix with edema (n = 9); appendix length >= 8 cm (n = 18); and palpable fecalith (n = 78). Histopathologic examination of appendix specimens revealed lymphoid hyperplasia with a fecalith (n = 32), fecalith only (n = 32), acute appendicitis (n = 20), normal anatomy (n = 18), fibrous obliteration (n = 9), lymphoid hyperplasia (n = 9), Enterobius vermicularis (n = 3),appendiceal neuroma (n 1), carcinoid tumor (n = 1), and mucoceles (n = 1). Conclusion. Although incidental appendectomy increased the wound infection rate and length of hospital stay, this procedure is necessary for the prevention of potential complications due to appendicitis when the exploration of the ileocecal region in patients undergoing donor hepatectomy reveals one or more of the following: appendix length >= 8 cm; dropsical, hyperemic, subserosal, nodular, and/or retrocecal appendix; and/or palpable fecaloma.Öğe Management of wet ascitic type of peritoneal tuberculosis: single center experience(Verduci Publisher, 2023) Gonultas, F.; Akbulut, S.; Sarici, K. B.; Toprak, S.; Kilci, B.; Bilgic, Y.; Kose, A.OBJECTIVE: We aimed to present our experience with the management of 17 patients with ascites who underwent diagnostic laparoscopy or laparotomy, and histologic con-firmation of wet ascitic type of peritoneal tuber-culosis (TB).PATIENTS AND METHODS: Between Janu-ary 2008 and March 2019, 17 patients whose as -cites were investigated by a gastroenterologist and who were thought to have non-cirrhotic as -cites were referred to our Surgery clinic for peri-toneal biopsy. The clinical, biochemical, radio-logical, microbiological, and histopathological data of the patients who underwent diagnostic laparoscopy or laparotomy were analyzed ret-rospectively. Histopathological examination of peritoneal tissue samples in hematoxylin-eo-sin-stained preparations revealed necrotiz-ing granulomatous inflammation with caseous necrosis and Langhans type giant cells. Eh-rlich-Ziehl-Neelsen (EZN) staining was studied with the suspicion of TB. Acid-fast bacilli (AFB) were detected in EZN stained slide. Histopatho-logical findings were also considered.RESULTS: Seventeen patients aged 18 to 64 years were included in this study. The most common symptoms were ascites and abdomi-nal distention, weight loss, night sweats, fever and diarrhea. Radiological examination revealed peritoneal thickening, ascites, omental cacking, and diffuse lymphadenopathy. Histopathologi-cally, necrotizing granulomatous peritonitis con-sistent with peritoneal TB were detected. While direct laparoscopy was preferred in sixteen pa-tients, laparotomy was preferred in the remain-ing one due to previous surgical procedures. However, seven were converted to open laparot-omy.CONCLUSIONS: Diagnosis of abdominal TB requires high index of suspicion, and the treat-ment should be prompt to reduce the morbidity and mortality associated with delay in treatment.Öğe The risk facotrs of mortality following liver transplantation in acute liver failure: Single center experience(Lippincott Williams & Wilkins, 2019) Sahin, T.; Sarici, K. B.; Karakas, S.; Kutluturk, K.; Aydin, C.; Yilmaz, S.[Abstract Not Available]Öğe Telescopic Biliary Reconstruction in Patients Undergoing Liver Transplantation With 1-Year Follow-up(Elsevier Science Inc, 2017) Karakas, S.; Sarici, K. B.; Ozdemir, F.; Ersan, V.; Ince, V.; Baskiran, A.; Kayaalp, C.Background. Biliary complications are important during liver transplantation because of their effect on recipient and graft survival, incidence, and the long treatment period. These complications are associated with 50% morbidity and 30% mortality rates in recent studies. One of the most important reasons for biliary anastomosis complications is arterial ischemia. We present the results of our telescopic biliary anastomosis technique performed on the mucosa of the main biliary duct. Patients and Methods. Fifty-six cases of telescopic biliary reconstruction were performed in 203 patients during 2015. Fifty cases and 52 patients who underwent standard reconstruction were chosen and compared. All patients had been scanned retrospectively. Statistical analyses were conducted with chi(2) and Mann-Whitney U tests for the complications that occurred during the first 3 months. A P value <.05 was considered significant. Results. No clinical or demographic differences were detected between the groups. About 90% of both groups were living donor liver transplantation cases. Five (10%) anastomotic leaks occurred in telescopic reconstruction group (n = 50), and 13 (25%) occurred in the standard reconstruction group (n = 52; P < .05). Conclusion. The arterial blood supply is better if the biliary anastomosis is made on the mucosal side of the main biliary duct. Early period anastomotic leaks may decrease significantly.
