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 Corona mortis: in vivo anatomical knowledge and the risk of injury in totally extraperitoneal inguinal hernia repair(Springer, 2016) Ates, M.; Kinaci, E.; Kose, E.; Soyer, V.; Sarici, B.; Cuglan, S.; Korkmaz, F.Corona mortis (CMOR) is the arterial and/or venous vascular communication(s) between the obturator and external iliac vessels. Totally extraperitoneal (TEP) inguinal hernioplasty can be associated with vascular complications especially during the fixation of the mesh. Theoretically, CMOR is an important nominee. But, the data in literature are insufficient about CMOR injury. Additionally, most of the studies about CMOR have been usually performed on cadavers. We aimed to reveal the preperitoneal vascular anatomy of inguinal area and provide in vivo knowledge about CMOR. The risk of arterial injury was also evaluated. The data of preperitoneal vascular anatomy of 321 patients who underwent TEP procedure between January 2005 and July 2014 were retrospectively evaluated. Mean age was 46 +/- 8.9 years, 53 females vs 268 males. 391 hemipelvises were evaluated. Two types of arterial structure were identified; (1) an aberrant obturator artery forming an anastomosis with branches of ordinary obturator artery; (2) a pubic branch of inferior epigastric artery. The incidence of arterial CMOR was 28.4 % and of any arterial structure was 45.0 %. An arterial CMOR was considered as thick (aeyen2 mm) or thin (< 2 mm). Injury of arterial CMOR during tack stapling on Cooper's ligament was seen in six cases (1.5 %). All of them were thin (< 2 mm) in structure. Venous CMOR was visible only under low pressure in work space. During TEP hernia repair, CMOR and/or pubic branch of inferior epigastric artery can be damaged. To prevent this complication, tacks should be stapled to Cooper's ligament close to symphysis pubis and dissection should be careful on the posterior surface of superior pubic ramus. Small caliber (< 2 mm) arterial CMOR is more prone to be injured during TEP procedure. To explore venous structures properly, pressure in workspace should be kept as low as possible.Öğe Donor Complications Among 500 Living Donor Liver Transplantations at a Single Center(Elsevier Science Inc, 2012) Ozgor, D.; Dirican, A.; Ates, M.; Gonultas, F.; Ara, C.; Yilmaz, S.Introduction. Living donor liver transplantation (LDLT) has become necessary because of the shortage of cadaveric organs. We retrospectively analyzed 500 living donor hepatectomies using the Clavien classification system for complications to grade their severity. Materials and methods. We retrospectively identified and applied the Clavien clasification to 500 consecutive donors who underwent right for LDLT left hepatectomy between January 2007 and August 2011. Results. The 149 complications were observed in 93 of 500 (18.6%) donors who were followed for a mean 30 months. There wan no donor mortality. Complications developed in 85 (18.6%) right 5 (35.7%) left, and 3 (10%) left lateral segment hepatectomy donors. The overall incidence of reoperations was 7.2%. Seventy-seven of 149 complications were grade I (51.6%) or 9 grade II (6%). The major complications consisted of 27 (18.1%) grade IIIa, 35 (23.4%) grade IIIb, and 1 (0.6%) grade IVa. Grade IVb and grade V complications did not occur. The most common problems were biliary complications in 14 of 181 donors (7.7%). Conclusion. Donors for LDLT experienced a range of complications.Öğe Evaluation of Potential Donors in Living Donor Liver Transplantation(Elsevier Science Inc, 2015) Dirican, A.; Baskiran, A.; Dogan, M.; Ates, M.; Soyer, V.; Sarici, B.; Ozdemir, F.Introduction. Correct donor selection in living donor liver transplantation (LDLT) is essential not only to decrease the risks of complications for the donors but also to increase the survival of both the graft and the recipient. Knowing their most frequent reasons of donor elimination is so important for transplantation centers to gain time. In this study we evaluated the effectiveness of potential donors in LDLT and studied the reasons for nonmaturation of potential liver donors at our transplantation center. Patients and Methods. We studied the outcomes of 342 potential living donor candidates for 161 recipient candidates for liver transplantation between January 2013 and June 2014. Donor candidates' gender, age, body mass index (BMI), relationship with recipient, and causes of exclusion were recorded. Results. Among 161 recipients, 96 had a LDLT and 7 had cadaveric liver transplantation. Twelve of the 342 potential donors did not complete their evaluation; 106 of the remaining 330 donor candidates were accepted as suitable for donation (32%) but 10 of these were excluded preoperatively. The main reasons for unsuitability for liver donation were small remnant liver size (43%) and fatty changes of the liver (38.4%). Other reasons were arterial anatomic variations, ABO incompatibility, and Gilbert syndrome. Only 96 of the candidates (29% of the 330 candidates who completed the evaluation) underwent donation. Effective donors were 29% of potential and 90.5% of suitable donors. Conclusions. In our center, 106 of 330 (32%) donor candidates were suitable for donation and the main reasons for unsuitability for liver donation were small remnant liver size and fatty changes of the liver.Öğe Evaluation of Potential Donors in Living Donor Liver Transplantation (vol 47, pg 1315, 2015)(Elsevier Science Inc, 2015) Dirican, A.; Baskiran, A.; Dogan, M.; Ates, M.; Soyer, V.; Sarici, B.; Ozdemir, F.[Abstract Not Available]Öğe The factors affecting development of low anterior resection syndrome (LARS) in patients undergoing sphincter preserving surgery for rectal cancer(Athens Medical Soc, 2020) Simsek, A.; Bayraktar, H.; Dirican, A.; Ozgor, D.; Ates, M.OBJECTIVE To investigate the incidence of major low anterior resection syndrome (LARS), using the LARS score, in patients who underwent sphincter-preserving surgery for rectal cancer, and to explore the factors affecting major LARS development. METHOD The medical records were retrospectively reviewed of patients, who were operated for rectal cancer at a tertiary center between January 2009 and October 2017. The inclusion criteria were: The absence of other colorectal or proctologic diseases, the application of anterior resection (high anterior resection, low anterior resection, extremely low anterior resection), follow-up of more than one year after the primary surgery, and follow-up of more than one year after protective ileostomy closure, and the absence of an unreversed stoma, ongoing treatment with chemotherapy or radiotherapy, recurrence, and metastatic disease. LARS was diagnosed using the LARS score developed by Emmertsen and Laurberg. RESULTS For the study period, 81 patients met the inclusion criteria, including 45 (55.5%) men and 36 (44.4%) women, with a mean age of 60.1 years. Of the 81 patients, 56 (69.1%) underwent chemotherapy and 43 (53%) underwent radiotherapy. Major LARS was detected in 29.6% of the patients. Univariate analysis revealed that radiotherapy, lower tumor location and a short interval after ileostomy closure had an effect on LARS development, and multivariate analysis indicated that incidence of LARS was higher in middle and lower rectal cancer. CONCLUSIONS There appears to be no harm in creating a protective ileostomy for LARS development, with regard to anastomosis safety and the planning of the adjuvant therapy. Neither radiotherapy, nor type of surgery had an effect on major LARS. As was expected, a high rate of major LARS was reported in lower rectal tumors.Öğe First laparoscopic totally extraperitoneal repair of Laugier's hernia: a case report(Springer, 2013) Ates, M.; Dirican, A.; Kose, E.; Isik, B.; Yilmaz, S.An atypical femoral hernia developing through the lacunar ligament is called Laugier's hernia. Preoperative diagnosis of these atypical hernias is very difficult because of their rarity and similar clinical appearance to conventional femoral hernias. A 52-year-old female presented with right groin swelling. During laparoscopic totally extraperitoneal (TEP) inguinal hernia repair, a hernia sac through an opening in the lacunar ligament was diagnosed and repaired with mesh covering the inguinal floor. The surgeon should be alert to the possibility of an atypical femoral hernia when examining patients with inguinal hernias. A laparoscopic approach should be chosen instead of a conventional approach for the treatment of femoral hernias because of its high diagnostic and therapeutic capacity for all types of femoral hernia, including Laugier's.Öğe Incarcerated Morgagni hernia provoked by pregnancy(Sage Publications Ltd, 2010) Oguzturk, H.; Ates, M.; Turtay, M. G.; Dogan, M.; Ince, V.Morgagni hernias are rare diaphragmatic hernias, usually occurring on the right and located in the anterior mediastinum. Herniation of abdominal contents is typically caused by an increase in intraabdominal pressure secondary to trauma, pregnancy or obesity. In this article, a 35-year-old pregnant woman with a Morgagni hernia diagnosed on chest X-ray is presented. Emergency laparotomy was performed with reduction of the herniation and repair of the diaphragmatic defect. To our knowledge, this is the first reported case of hernia in a pregnant woman with incarcerated bowel presenting with respiratory and gastrointestinal symptoms from Turkey. (Hong Kong j.emerg.med. 2010;17:392-394)Öğe Liver Transplantation following Blunt Liver Trauma(Elsevier Science Inc, 2012) Hatipoglu, S.; Bulbuloglu, E.; Ates, M.; Kayaalp, C.; Yilmaz, S.Due to developing medical technology worldwide, an increasing number of liver transplantations are performed for various indications. Liver transplantation has a limited but important role in specific life-threatening liver trauma cases, when initial therapeutic options fail to control the bleeding or when liver failure ensues. Herein we have reported a patient who required liver transplantation at 18 days after blunt liver trauma with acute liver failure. This case report suggested that liver transplantation is a potential treatment modality for a selected group of patients including pedratric cases who experience acute or subacute liver failure secondary to blunt trauma.Öğe Living Donor Liver Transplantation for Mushroom Intoxication Caused Acute Liver Failure(Lippincott Williams & Wilkins, 2017) Dirican, A.; Yilmaz, M.; Baskiran, A.; Ozgor, D.; Ates, M.; Koc, S.; Ince, V[Abstract Not Available]Öğe Outcomes of Left-Lobe Donor Hepatectomy for Living-Donor Liver Transplantation: A Single-Center Experience(Elsevier Science Inc, 2013) Usta, S.; Ates, M.; Dirican, A.; Isik, B.; Yilmaz, S.Living-donor liver transplantation (LDLT) is an excellent option for patients with end-stage liver disease in situations of donor shortage. The aims of this study were to evaluate our experience with left-lobe donor hepatectomy for LDLT and to grade postoperative complications using the 5-tier Clavien classification system. Data from medical records of 60 adult living liver donors (30 men, 30 women) who underwent left-lobe hepatectomy between November 2006 and April 2012 were reviewed. The median donor age was 31.7 +/- 8.9 (range, 19-63) years. Sixteen complications were observed in 12/60 (20%) donors. Complications developed in 6/15 (40%) donors who underwent left hepatectomy and in 6/45 (13.3%) donors who underwent left lateral segmentectomy. Seven of 16 (43.7%) complications were Grade I and 2 (12.5%) were Grade II. Major complications consisted of 4 (25%) Grade IIIa and 3 (18.7%) Grade IIIb complications; no Grade IVb or V complications occurred. The most common complication was biliary, occurring in 7 (11.6%) donors and comprising 43.7% of all 16 complications. The mean duration of follow-up was 30 +/- 7.1 (range, 2-58) months. No donor mortality occurred. Left-lobe donor hepatectomy for LDLT, which does not benefit the completely healthy donor, was performed safely and with low complication rates, but carries the risk of morbidity. Low morbidity rates following living-donor hepatectomy can be expected when surgical and clinical monitoring and follow-up are adequate and the surgeon has gained increased experience.Öğe Partial Cholecystectomy: A Technique That Makes Hilar Dissection Easier in Recipient Hepatectomy(Elsevier Science Inc, 2014) Ara, C.; Ozdemir, F.; Ates, M.; Ozgor, D.; Kutluturk, K.Background. Intraoperative blood loss and red blood cell transfusion requirements have a negative impact on outcome after orthotopic liver transplantation. In this study we compared blood transfusion requirements, bile duct injury, and dissection of hepatic artery rates in the patients with or without partial cholecystectomy during recipient hepatectomy. Methods. From December 2008 to August 2011, 100 recipient hepatectomies were performed by the same surgeon. Patients were divided into 2 groups. The first group included patients with partial cholecystectomy, and the other group patients without partial cholecystectomy. Each group consisted of 50 patients. Results. In recipient hepatectomy group without partial cholecystectomy, intraoperative blood transfusions were in the range of 3-11 units (mean, 6.3 units). In this group there were 4 hepatic artery dissections and 2 bile duct injuries. In the group with partial cholecystectomy, intraoperative blood transfusions were in the range of 0-7 units (mean, 3.1 units). In this group there was 1 hepatic artery dissection. There were no operative mortalities in either group. Conclusions. We recommend partial cholecystectomy during recipient hepatectomy of cirrhotic patients, particularly with hydropic gallbladders, because bleeding from the points of adherent gallbladder during mobilization of the liver is diminished and fewer artery dissections and bile duct injuries develop, because the procedure facilitates dissection of the hilar structures.Öğe Pulmonary Complications After 1150 Living Donor Hepatectomies(Elsevier Science Inc, 2015) Ates, M.; Kinaci, E.; Dirican, A.; Sarici, B.; Soyer, V.; Koc, S.; Yilmaz, S.Aim. Donor safety is the major concern in living-donor liver transplantation. Studies in literature related to donor hepatectomy (DH) have generally considered intra-abdominal complications. The aim of this study is to specifically evaluate pulmonary complications (PCs) after DH. Materials and Methods. We evaluated retrospectively 1150 living donors who underwent to DH between January 2007 and July 2014. Patients with PCs, such as pneumonia, pleural effusion, pneumothorax, and respiratory insufficiency, were considered. A complication was considered only when it was clinically apparent and/or requiring interventions. Any special diagnostic tool was used to expose the clinically silent pathologies. Results. A total of 986 right hepatectomies (RH) and 164 left hepatectomies (LH) (left lobectomy or left lateral segmentectomy) were performed in the study interval. There were 18 (1.6%) donors with PCs (15 males and 3 females). Mean age was 33.8 +/- 9.3 years (18-51). Mean hospital stay was 23.8 +/- 13.5 days (5-62). Presented PCs were pleural effusion (n = 5, 0.4%), pneumonia (n = 4, 0.3%), combinations (n = 2, 0.2%), pneumothorax (n = 2, 0.2%), and acute respiratory insufficiency (n = 5, 0.4%). Sixteen cases (1.7%) were seen after RH, whereas 2 cases (1.2%) were seen after LH (P = 1.000). Conclusion. The most common PCs after living donor hepatectomy were pleural effusion and acute respiratory insufficiency. There was no significant difference between RH and LH. It is possible to overcome those PCs with careful monitoring and timely and appropriate treatment.Öğe Right Lobe Living Donor Liver Transplantation for Adult Patients with Acute Liver Failure: A Single-Center Experience in Turkey(Lippincott Williams & Wilkins, 2012) Ates, M.; Dirican, A.; Hatipoglu, S.; Ince, V; Isik, B.; Yilmaz, M.; Cemallettin, A.[Abstract Not Available]Öğe Right-Lobe Living-Donor Liver Transplantation in Adult Patients With Acute Liver Failure(Elsevier Science Inc, 2013) Ates, M.; Hatipoglu, S.; Dirican, A.; Isik, B.; Ince, V.; Yilmaz, M.; Aydin, C.Background. Right-lobe living-donor liver transplantation (RLDLT) is an excellent option to reduce donor shortages for adult patients with acute liver failure (ALF). The aim of this study was to evaluate the etiologies and outcomes of 30 consecutive adult patients who underwent emergency RLDLT for ALP. Methods. Between January 2007 and September 2011, we examined data from medical records of patients with ALF who underwent RLDLT. Results. Their mean age was 32.2 +/- 13.05 years. The etiologies of ALP were acute hepatitis B (n = 11; 36.6%), hepatitis A (n = 4; 13.3%), drug intoxication (n = 4; 13.3%), pregnancy (n = 2; 6.7%), hepatitis B with pregnancy (n = 1; 3.3%), mushroom intoxication (n = 1; 3.3%), and unknown (n = 7; 23.3%). The mean hepatic coma grade (Model for End-Stage Liver Disease score) was 34.13 +/- 8.72. The 43 (48.7%) postoperative complications were minor (grades I-II) and 44 (51.3%) were major (grades III-V). Reoperation was required in 14 of 30 (47%) recipients (grades IIIb-IVa). Deaths occurred owing to pulmonary (n = 2), cardiac (n = 1), septic (n = 2), or encephalopathic (n = 4) complications. The mean durations of intensive care unit stay and postoperative hospitalization were 3.2 +/- 2.3 and 29.5 +/- 23 days, respectively. The survival rate was 70%. The mean follow-up duration was 305 days (range, 1-1582). Conclusion. Liver transplantation is potentially the only curative modality, markedly improving the prognosis of patients with ALP. The interval between ALF onset and death is short and crucial because of the rapid, progressive multiorgan failure. Thus, RLDLT should be considered to be a life-saving procedure for adult patients with ALF, requiring quicker access to a deceased-donor liver graft and a short ischemia time.Öğe Significance and Outcome of Living-donor Liver Transplantation in Acute Mushroom Intoxication(Wolters Kluwer Medknow Publications, 2018) Baskiran, A.; Dirican, A.; Ozgor, D.; Kement, M.; Koc, S.; Sahin, T. T.; Ates, M.Introduction: Mushroom intoxication ( MT) can lead to acute liver injury which may result in Mushroom intoxication-related liver failure ( M-ALF) requiring liver transplantation ( LT). In the present study, we want to share the experience of our institute regarding living-donor LT ( LDLT) due to mushroom poisoning. Aim: The aim of this study is to identify the predictors of poor prognosis in patients with ALF secondary to mushroom intoxication requiring LDLT. Materials and Methods: All patients with MT between 2008 and 2016 were evaluated. Demographics, symptoms, interval between symptoms and admission to our institute, laboratory data, model for end-stage liver disease ( MELD)/ pediatric end-stage liver disease ( PELD) scores, clinical course, and outcomes of supportive therapy and LT were evaluated. There were two groups in the study: Group A = responsive to supportive therapy ( n = 9) versus Group B = unresponsive to supportive therapy ( n = 9). Results: During the study, a total of 18 patients were admitted with M-ALF. Twelve ( 66.7%) of them were female, and the mean age was 39.9 +/- 18.2 years. All of the nine patients in Group A fully recovered with supportive therapy. In Group B, one patient died during waiting period for LT and 8 patients received LDLT LDLT. Three of the eight patients who were transplanted died in the postoperative early period within postoperative 5 days. The patients in Group B had significantly higher MELD/ PELD scores and encephalopathy rate than in Group A ( P < 0.05). International normalized ratio ( INR), bilirubin, ammonium levels, and platelet count were significantly different between groups ( P < 0.05). The patients in Group B had significantly longer interval before admission to our institute ( P < 0.05). Conclusion: The presence of encephalopathy, higher MELD/ PELD, INR, bilirubin, ammonium levels, and lower platelet count was related to poor prognosis in MT. LDLT provides a good therapeutic option in patients with M-ALF. The time is a crucial factor in successful treatment of MT. Early admission to a tertiary referral center with expertise in LT results in a better prognosis and increased survival following M-ALF.Öğe The simple suture laparoscopic repair of peptic ulcer perforation without an omental patch(Springer, 2012) Ates, M.; Dirican, A.[Abstract Not Available]
