RESUMEN

BACKGROUND: Living donor liver transplantation (LDLT) has become an increasingly common surgical option because the number of cadaveric donors is insufficient to fulfill the organ needs of patients facing end-stage cirrhosis. Many centers are investigating different surgical techniques to achieve lower complication rates. We aimed to examine our complication rates in light of demographic data, graft data, and perioperative findings as a single-center experience. METHODS: The study included one hundred and three patients who underwent LDLT for end-stage liver cirrhosis. Demographic data; sex; age; blood group; Model for End-Stage Liver Disease score; Child score; etiology; liver side; graft-to-recipient weight ratio; hepatic artery, portal vein, and bile anastomosis type rates; anhepatic phase; cold ischemia time; operation time; and blood product transfusion rates were analyzed. Biliary complications in patients with single or multiple biliary anastomoses, right or left liver transplants, and with or without hepatic artery thrombosis were analyzed statistically. RESULTS: There was no significant difference in biliary complications between patients who underwent single or multiple bile anastomosis (P = .231) or patients receiving right lobe and left lobe transplants (P = .315). Although there was no statistically significant difference in the rate of portal vein thrombosis between the regular and reconstructed portal vein anastomosis groups (P = .693), the postoperative portal vein thrombosis rate was statistically higher in patients with left lobe transplants (P = .044). CONCLUSIONS: Vascular and biliary complication rates can be reduced with increasing experience.

RESUMEN

BACKGROUND: Our objective was to determine the levels of heavy metals, oxidants, and antioxidants in liver tissue of patients with chronic liver disease (CLD) compared with healthy living liver donors (LLDs). METHODS: We obtained liver specimens from patients undergoing liver transplant for CLD. Samples were also obtained from LLDs. Biochemical analyses were performed on all samples, and the levels of liver tissue, heavy metal, and oxidant-antioxidants biomarker levels in patients with CLD were compared with those measured in LLDs. RESULTS: One hundred and eighteen individuals were included for analyses. Fifty-nine were patients with CLD, and 59 were LLDs. The median levels of liver tissue of superoxide dismutase (P = .009), glutathione peroxidase (P = .042), total oxidant status (P = .006), oxidative stress index (P < .001), and copper (P = .035) were prominently more elevated in CLD than LLDs. On the other hand, the median levels of liver tissue of cadmium (P < .001), selenium (P = .042), and zinc (P < .001) levels were more elevated in the LLDs than patients with CLD. The 2 groups were similar in terms of total antioxidant status, manganese, arsenic, and lead levels. CONCLUSIONS: Superoxide accumulation in the liver was higher in patients with CLD. Concerning heavy metals, only the median tissue copper was elevated in patients with CLD with higher Cu/Zn ratio. Cadmium, selenium, and zinc were significantly higher in the healthy LLDs.

RESUMEN

This study aimed to demonstrate the efficacy of our diagnostic and therapeutic management algorithm and catheter-assisted (percutaneous transhepatic biliary tract drainage [PTBD] or transanastomotic feeding tube) hepaticojejunostomy (HJ) procedures in living liver donors (LLDs) with biliary complications. Living donor hepatectomy (LDH) was performed between September 2005 and April 2021 in 2 489 LLDs. Biliary complications developed in 220 LLDs (8.8%), 136 of which were male, and the median age was 29 (interquartile range [IQR]: 12) years. Endoscopic sphincterotomy ± stenting was performed in 132 LLDs, which was unsuccessful in 9 LLDs and required HJ. Overall, 142 LLDs underwent interventional radiologic procedures. Fifteen LLDs with biliary complications underwent HJ (PTBD catheter = 6 and transanastomotic feeding tube = 9) at a median of 44 days (IQR: 82). Following HJ, 14 LLDs did not have any complications throughout the median follow-up period of 1619 days (IQR: 1454). However, percutaneous dilation for HJ anastomotic stricture was performed in one patient. Biliary complications are very common following LDH; therefore, surgeons in the field should have a low threshold to perform HJ for biliary complications that persist after other treatments. Our catheter-assisted HJ techniques demonstrated a high success rate and aided HJ in a hostile abdomen during revisional surgery.

RESUMEN

AIM: We classified anatomical localisation tumours of patients diagnosed with colorectal cancer and undergoing surgery as right and left colon and we aimed to determine how this funding affects the prognosis of the disease and survival times. METHODS: In our study, 521 patients who applied to the general surgery outpatient clinic of Inönü University Turgut Özal Medical Center 19.06.2009 and 15.08.2019 between dates and operated with a diagnosis of colorectal cancer files were reviewed retrospectively. The patients' data were compared as age, gender, genetic predisposition, stage of tumour, distance to surgical margins (distal and radial), size, number of lymph nodes, metastasising organs, colon macroscopic features, chemotherapy and survival. RESULTS: In total, 42.6% of the patients were female and 57.4% were male. The average age of all patients is 59.79. The average age of women was 60.39 ± 1.023 and the average age of male patients was 59.35 ± 1.800. The anatomical regions where colorectal cancer was most common were rectum, colon sigmoideum and caecum. 40.5% of the patients had a tumour located in the right colon, while 59.5% had a tumour in the left colon. When the distal surgical margin (P = .002), proximal surgical margin (P = .001), tumour size (P = .001) and the number of removed lymph nodes (P = .002) were evaluated in these patients. The mean survival in the right colon was 71.499 ± 3.589 months and in the left colon was 71.121 ± 2.953 months. The longest survival was 76.856 ± 6.117 months in colon ascendens, while the shortest survival was calculated as 57.399 ± 4.671 months in flexura coli dextra. CONCLUSION: We are thinking that in colorectal cancer, the anatomical localisation of the tumour can hold an important place to determine the clinical differences such as, the disease symptoms, course, treatment options and survival status.

RESUMEN

OBJECTIVE: In this retrospective study, we compared the postoperative complications by using both the Clavien-Dindo classification and the Revised 2016 International Study Group on Pancreatic Surgery (ISGPS) classification methods after pancreaticoduodenectomy. MATERIALS AND METHODS: The data of patients were retrospectively reviewed. Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) were performed on 41 and 40 patients, respectively. The patients were assigned into two groups for anastomosis types and compared with each other according to postoperative complications. The postoperative follow-up period of the patients was limited to 90 days. RESULTS: No significant difference was detected between the two groups in terms of gender (P = .581) and age (P = .809). According to the Clavien-Dindo classification system, grade 1 complication rates were 29.3% and 35.0% in PJ and PG groups, respectively. Also, grade 2 complication rates were 34.1% and 32.5% in PJ and PG groups, respectively. Besides, grade 3B complication rates were 9.8% and 17.5% in PJ and PG groups, respectively. No grade 3A, grade 4A, and grade 4B complications were detected in both groups. But, grade 5 complications rates were 2.4% and 5.0% in PJ and PG groups, respectively. Based on the ISGPS classification system, the pancreatic fistulas were classified. The biochemical leak rates were calculated as 26.8% and 37.5% in PJ and PG groups, respectively. The rates were 14.6% and 10% in PJ and PG groups, respectively, for grade B complications. Also, grade C complication rates were 9.75% and 12.5% in PJ and PG groups, respectively. No statistically significant differences were detected between the two groups for postoperative complications. CONCLUSION: The evidence from this retrospective study suggests that there is no difference between the two types of pancreatic anastomosis techniques (PJ or PG) in terms of the rate of postoperative complications.

RESUMEN

BACKGROUND: Since the first living donor liver transplantation (LDLT) was performed by Raia and colleagues in December 1988, LDLT has become the gold standard treatment in countries where cadaveric organ donation is not sufficient. Adequate hepatic venous outflow reconstruction in LDLT is essential to prevent graft congestion and its complications including graft loss. However, this can be complex and technically demanding especially in the presence of complex variations and congenital anomalies in the graft hepatic veins. CASE SUMMARY: Herein, we aimed to present two cases who underwent successful right lobe LDLT using a right lobe liver graft with rudimentary or congenital absence of the right hepatic vein and describe the utility of a common large opening drainage model in such complex cases. CONCLUSION: Thanks to this venous reconstruction model, none of the patients developed postoperative complications related to venous drainage. Our experience with venous drainage reconstruction models shows that congenital variations in the hepatic venous structure of living liver donors are not absolute contraindications for LDLT.

RESUMEN

INTRODUCTION: Liver transplantation remains the main curative treatment method for hepatocellular carcinoma. There are several criteria for hepatocellular carcinoma to be eligible for liver transplantation, and it depends on main transplantation centers worldwide. Locoregional treatments and downstaging protocols are used for either to achieve these criteria or to prevent drop outs on the transplant waiting lists. But who can benefit from these bridging therapies effectively for the main purpose of curative treatment? Main contraindications are known for locoregional treatments like cirrhosis or low hepatic function, total main portal vein occlusion, and extrahepatic metastasis. HCCs, which are confined to liver but have high tumor burden, remains the main controversial issue. AIM: On this aspect, we reviewed the literature for downstaging protocols for hepatocellular carcinoma with their effect on survival and recurrence rates after liver transplantation. CONCLUSION: Although candidates for downstaging is still controversial, with the absence of main contraindications, LRT can be applied to selected HCCs, which have a certain degree of tumor burden.

RESUMEN

Survival was examined from a Turkish liver transplant center of patients with HCC, to identify prognostic factors. Data from 215 patients who underwent predominantly live donor liver transplant for HCC at our institute over 12 years were included in the study and prospectively recorded. They were 152 patients within and 63 patients beyond Milan criteria. Patients beyond Milan criteria were divided into two groups according to presence or absence of tumor recurrence. Recurrence-associated factors were analyzed. These factors were then applied to the total cohort for survival analysis. We identified four factors, using multivariate analysis, that were significantly associated with tumor recurrence. These were maximum tumor diameter, degree of tumor differentiation, and serum AFP and GGT levels. A model that included all four of these factors was constructed, the 'Malatya criteria.' Using these Malatya criteria, we estimated DFS and cumulative survival, for patients within and beyond these criteria, and found statistically significant differences with improved survival in patients within Malatya criteria of 1, 5, and 10-year overall survival rates of 90.1%, 79.7%, and 72.8% respectively, which compared favorably with other extra-Milan extended criteria. Survival of our patients within the newly defined Malatya criteria compared favorably with other extra-Milan extended criteria and highlight the usefulness of serum AFP and GGT levels in decision-making.

RESUMEN

OBJECTIVES: The most common intra-abdominal complication following loop ileostomy closure (LIC) is postoperative ileus (POI). The aim of the study was to determine the risk factors of POI development following LIC and make recommendations for its prevention. MATERIAL AND METHODS: In this study, patients having undergone LIC with peristomal incision following distal colorectal surgery were included. Clavien-Dindo classification was used to evaluate postoperative complications. POI and postoperative leakage were defined based on clinical and radiological criteria. The Centers for Disease Control and Prevention 2017 criteria were used to diagnose surgical site infection (SSI). Postoperative bleeding was diagnosed one day after surgery if there was a >2 g/dL or ≥15% decrease in the hemoglobin level. RESULTS: Seventy-nine patients were included into the study. In nine of the patients POI developed, six had SSI, five had postoperative bleeding, and two had anastomosis leakage. In the univariate analysis; age <60 years (p= 0.02), presence of comorbidity (p= 0.007), using an open technique in the first surgery (p= 0.02), performing total colectomy in the first surgery (p= 0.048), performing hand-sewn anastomosis of LIC (p= 0.01), and postoperative blood transfusion (p= 0.04) were found to be risk factors for POI. Performing hand-sewn anastomosis of LIC (p= 0.03) and using an open technique in the first surgery (p= 0.03) were found to be independent variables for POI risk. CONCLUSION: Using an open technique in the first surgery and performing a hand-sewn anastomosis of LIC may increase POI.

RESUMEN

Gardner's syndrome (GS) is a rare syndrome with autosomal dominant inheritance, which is characterized by multiple intestinal polyps, dental anomalies, desmoid tumors, and soft tissue tumors. All gastrointestinal symptoms seen in GS are associated with the underlying familial adenomatosis polyposis and abdominal desmoid tumors, with the most common symptoms being anemia, lower gastrointestinal bleeding, abdominal pain, diarrhea, obstruction, and mucous defecation. To our best knowledge, no case of GS that has presented with gastrointestinal perforation and bleeding has ever been reported in the English language medical literature. A 37-year-old male who had been diagnosed with GS five years earlier was referred to our clinic for lower gastrointestinal bleeding. Despite the absence of a bleeding focus on conventional angiography, the patient was operated on with laparotomy, due to the persistence of both signs and symptoms of mild peritonitis. On the laparotomy, the patient was noted to have areas of perforation in the duodenum, splenic flexura, and mid-rectum. The third and fourth part of the duodenum, the proximal 15 cm segment of the jejunum, a 10 cm segment of the terminal ileum, the whole colon, and the upper and middle rectum were resected, and duodeno-jejunal side-to-side anastomosis and terminal ileostomy were performed. The histopathological analysis of the large mass measuring 30 cm × 20 cm was reported as a desmoid tumor. The pathological examination of the tumor foci detected in the colonic specimen revealed poorly differentiated adenosquamous carcinoma.

RESUMEN

Gastrointestinal stromal tumors (GISTs) are the most common non-epithelial (mesenchymal) tumors of the gastrointestinal tract. Although GISTs appear as solid and well-circumscribed lesions in most patients, they may also appear as solid- cystic (mixed) or pure cystic lesions due to reasons like intra-tumor hemorrhage and necrosis in a very small percentage of patients. Hence, cystic GISTs mostly lead to a diagnostic dilemma. In this paper we aimed to report a case of pure cystic giant GIST that was drained percutaneously twice after being misdiagnosed as a mesenteric cyst. An 83-yearold man was operated for a pre-diagnosis of a recurrent mesenteric cyst. The operation was started with the three-trocar laparoscopic technique. Six thousand milliliters of purulent fluid were drained from the cystic lesion. Then, a mini incision was performed above the umbilicus and the cyst and the distal ileal segment where it was originated were removed from the abdominal cavity. After the resection of a 15-cm ileal segment together with the cystic lesion, an intestinal anastomosis was performed. The histopathological and immunohistochemical findings showed that the mass was a GIST (size: 20 cm, mitosis: 3/50 HPF, Ki 67: %15, CD117: positive, DOG-1: positive). The patient was closely followed without imatinib therapy. KEY WORDS: Abscess, Cystic Degeneration, GIST, Mistreatment.

RESUMEN

BACKGROUND: Normal physiologic changes during pregnancy result in similar laboratory and symptomatology changes as those during acute appendicitis (AA), making the diagnosis extremely difficult. The aim of the present study was to analyze the efficacy of conventional laboratory and radiologic tests in the diagnosis of AA according to different stages of pregnancy. METHODS: Twenty-five pregnant patients with pathologically confirmed AA operated at our department between 2012 and 2017 were retrospectively analyzed in terms of changes in conventional laboratory parameters as well as neutrophil-to lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios to aid the diagnosis of AA according to different stages of pregnancy. RESULTS: There were no significant changes in C-reactive protein levels, leukocyte and neutrophil counts, and accuracy of ultrasonography between patients in the first (group 1) and second + third trimesters (group 2) (p>0.05). Lymphocyte count was significantly lower (p>0.05), whereas NLR and PLR were significantly higher in group 2 (p<0.05). CONCLUSION: Laboratory values change significantly during pregnancy, and NLR and PLR seems to be valuable tools for evaluating AA in a stage-specific manner in pregnant patients.

RESUMEN

OBJECTIVE: To determine the relationship between a transplant center's experience and life-threatening or nearly life-threatening complications during living donor hepatectomy (LDH). METHODS: The medical records of 1140 patients who underwent LDH were analyzed. To determine the relationship between life-threatening complications and a transplant center's experience, the following comparisons between LDH cases were performed: first 100 vs subsequent 100; first 100 vs subsequent 1040; first 200 vs subsequent 940; right hepatectomy vs left hepatectomy; and first 5 years of experience vs subsequent 5 years. RESULTS: A total of 36 life-threatening or nearly life-threatening complications developed in 34 of 1140 (2.98%) healthy individuals undergoing LDH. Of these, 5 occurred intraoperatively, 26 within 1 month, and 5 beyond 1 month. The most common complications were biliary problems and postoperative bleeding. None of the donors died at follow-up. One donor underwent deceased donor liver transplantation (DDLT) for severe hepatic failure. Only 2 comparisons were significantly different with regard to life-threatening complications: the first 100 vs the subsequent 1040 (P = .03) and the first 200 vs the subsequent 940 (P = .01). CONCLUSION: This study indicates that the incidence of life-threatening or nearly life-threatening complications are reduced by increased center experience (>200 LDHs).

RESUMEN

OBJECTIVE: Gallbladder cancer (GBC) is a rare clinical entity that has a poor prognosis. Radical resection with meticulous lymph node dissection is the only treatment option. The aim of the present study is to evaluate the efficacy of radical resection for GBC in the early postoperative period with the viewpoint of clinicopathological correlation. METHODS: Patients (n=24) who underwent radical resection with lymph node dissection for GBC between 2015 and 2017 were included. Demographic data, histopathologic tumor type, preoperative tumor markers, pathologic tumor size/stage (depth of invasion), lymph node metastasis and metastasis rates, and postoperative early mortality were evaluated. The patients were grouped in two groups according to lymph node metastases: Group 1 (without lymph node metastasis) and Group 2 (with lymph node metastasis). RESULTS: The median age of the patients in Group 1 and Group 2 was 65 (range, 42-89) years and 68 (range, 48-87) years, respectively (p>0.05). The female/male ratio in Group 1 and Group 2 was 4/4 and 13/3, respectively (p>0.05). There was a tendency for increased metastasis in Group 2 compared with Group 1 (31% vs. 0%) (p>0.05). Also, 88% of the tumors in Group 2 were in the advanced stage, whereas the rate was 37% in Group 1 (p<0.05). There was early postoperative mortality in seven patients who underwent resection. Four of the seven patients (43%) were from Group 2 and three (37%) from Group 1 (p>0.05). CONCLUSION: Lymph node metastasis in GBC indicates advanced tumor stage. This causes a more complex surgical resection and therefore results in higher early postoperative mortality.

RESUMEN

OBJECTIVE: This study was conducted to present the preliminary results of seven patients treated with sphinctero-vagino-perineoplasty for secondary repair of obstetric anal sphincter injuries. MATERIALS AND METHODS: This retrospective study was conducted on the records of seven patients who underwent secondary repair of obstetric anal sphincter injuries at the colorectal surgery unit of a tertiary care center between February 2015 and December 2017. RESULTS: All patients with solid stool incontinence were fully recovered at postoperative month 3. The Wexner incontinence score was significantly improved (decreased from 14.12 [range: 8-20] to 2.28 [range: 1-4]). The complication rate was 85.7% (wound infection, abscess, hematoma, detachment). CONCLUSION: Combined repair of anal sphinchters, perineal body, superficial transverse perineal muscles, and bulbospongious muscles, which contribute to anal continence, may improve surgical outcomes in patients with obstetric anal sphincter injuries.

RESUMEN

Reconstruction of anomalous portal vein branching (APVB) during right lobe living donor liver transplantation (LDLT) can be challenging. The goal of this article is to describe our surgical technique, named the Malatya Approach, in case of APVB during right lobe LDLT. The technique unifies the APVB and obtains a funnel-shaped common extension with a circumferential fence by a saphenous vein conduit. In total, 126 (10.6%) of 1192 right lobe grafts had APVB that were divided into 2 groups according to the adopted surgical techniques: the Malatya Approach group (n = 91) and the previously defined other techniques group (n = 35). Both groups were compared regarding portal vein thrombosis (PVT), postoperative 90-day mortality and survival. PVT developed in 3 patients (3.3%) in the Malatya Approach group and developed in 10 (28.6%) patients for the other group (P < 0.001). There were 8 (8.8%) 90-day mortalities in the Malatya Approach group (1 PVT related) and 15 patients (9 PVT related) died in the other techniques group (P < 0.001). Mean follow-up time for both groups was similar (999.1 days for the Malatya Approach group versus 1024.7 days for the other group; P = 0.47), but longterm survival in the Malatya Approach group was better than in the other group (84.6% versus 40%; P < 0.001). Multivariate analysis revealed that the Malatya Approach group showed less PVT development and longer survival (P < 0.001). This technique is promising to avoid PVT and mortalities in cases of APVB during right lobe LDLT. Liver Transplantation 23 751-761 2017 AASLD.

RESUMEN

BACKGROUND: The identification of retropubic vasculature is not easy under the pressure of insufflated gas during totally extraperitoneal (TEP) inguinal hernioplasty. We aimed to present the usefulness of a maneuver that allows the clear identification of retropubic vasculature. METHODS: Vascular anatomy on the retropubic surface in 364 patients who underwent the TEP procedure from January 2005 to September 2015 was evaluated. In patients after July 2014, the pressure in the workspace was decreased from 14 to 8 mmHg before fixation of the mesh to clearly identify the veins. The results before and after July 2014 were compared. RESULTS: Demographic features were not significantly different between two periods. The number of hemipelvises in the first and second periods was 398 and 77, respectively. The rate of identification of venous corona mortis was 31% in the second period, whereas it was 1.0% in the first period (P = .000). The identification of thick (5.5% versus 10.3%; P = .123) and thin (22.8% versus 36.3%; P = .014) arterial structures and their sum were increased in the second period (28.4% versus 46.7%; P = .002). The rate of retropubic bleeding was zero in the second period, while it was 1.5% in the first period. CONCLUSIONS: During TEP hernioplasty, the pressure of insufflated gas more than 10 mmHg in the preperitoneal space hinders the correct identification of vessels on the retropubic surface. The proposed maneuver, to decrease the pressure in the workspace to 8 mmHg, can provide clear identification of all vessels, which decreases the potential risk of vascular injury.

RESUMEN

PURPOSE: Acute appendicitis is the most common surgical abdominal emergency. In the early diagnosis of acute appendicitis, the fact that there is no a sign which could be a reliable indicator in most of the patients increases the complications. In this study we aimed to search the relation between Ultrasonography(US) findings in patients with diagnosis of acute appendicitis and postoperative histopathologic investigation on remoced appendix.. MATERIALS AND METHODS: The files of 174 patients who came in our emergency department with lower right abdominal pain were studied retrospectively from January 2013 to May 2014. Of them, 26 patients were excluded, because these patients were not studied with US. US findings and histopathology reports of 148 patients with suspected acute appendicitis and studies preoperatively with abdominal US were enrolled. Greater than 6-mm diameter of the appendix under compression was accepted as positive sign of appandicitis in US. The demographic characteristics of the patients, US findings (acut appendicitis or not) and the pathology results were recorded on the standard proform. RESULTS: Of these 148 patients, 100 were acute appendicitis in preoperative US, and of these 100 patients, 93 histopathologic reports were acute appendicitis, 7 were normal appendices. The sensitivity of US was 75.6 % and specificity was 72 %. Positive predictive value (PPV) was 93 %, negative predictive value (NPV) was 14.6 % and the accuracy of US value was 81.7%. As a result, although US in diagnosis of acute appendicitis is a reliable technique, negative result doesn't mean no acute appendicitis. In order to determine an accurate diagnosis of acute appendicitis clinical and laboratoary findings should be assessed together. KEY WORDS: Abdominal pain, Acute appendicitis, Ultrasonography.

RESUMEN

OBJECTIVES: Although the main factors responsible for donor deaths after living-donor liver transplant are liver failure and sepsis, the most common donor complications are associated with the biliary tract. MATERIALS AND METHODS: Between April 2006 and May 2012, five hundred ninety-three donors underwent living-donor hepatectomy procedures for living-donor liver transplants. The mean age of donors was 31.0 ± 9.9 years and the ratio of men to women was 341:252. Of all donors, 533 (89.9%) underwent a right lobe hepatectomy, 45 (7.6%) underwent a left lateral segmentectomy, and 15 (2.5%) underwent a left hepatectomy. RESULTS: Biliary complications were observed in 51 liver donors (8.6%). Based on the Clavien-Dindo classification, grade I and grade II complications were 3.2% and 0%, while grade IIIa and grade IIIb complications were observed in 3.5% and 1.85% of cases. Right lobe donor biliary complications occurred at the rate of 8.2% in 44 donors. Grade IV and grade V complications were not observed. Grade IIIa complications necessitating radiologic and endoscopic procedures were observed in 21 liver donors (3.5%). Bile leakage unresponsive to medical therapy was detected in 19 donors (3.2%). Nasobiliary catheters were placed in 3 of 19 donors and internal stents were placed in 1. Two sessions of balloon dilatation were performed in the 2 grade IIIb donors (0.33%). Biliary strictures observed in 2 right lobe donors and 1 left lobe donor was treated by hepaticojejunostomy an average of 14 months after surgery. CONCLUSIONS: Avoidance of intraoperative issues and early recognition of bile leakage are fundamental in preventing complications in living-donor liver transplant donors.
