Diagnostic and therapeutic management algorithm for biliary complications in living liver donors.

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.

Investigation of clinical and pathological findings due to anatomical localisation in patients with colorectal cancer.

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.

Life-threatening or nearly life-threatening complications in living liver donors.

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).

Reconstruction of Anomalous Portal Venous Branching in Right Lobe Living Donor Liver Transplantation: Malatya Approach.

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.

Incisional hernia in recipients of adult to adult living donor liver transplantation.

BACKGROUND: After receiving a living donor liver transplant (LDLT), an incisional hernia is a potentially serious complication that can affect the patient's quality of life. In the present study we evaluated surgical hernia repair after LDLT. MATERIALS AND METHODS: Medical records of patients who underwent surgery to repair an incisional hernia after LDLT in Turgut Ozal Medical Center between October 2006 and January 2010 were evaluated in this retrospective study. A reverse-T incision was made for liver transplantation. The hernias were repaired with onlay polypropylene mesh. Age, gender, post-transplant relaparatomy, the type, the result of surgery for the incisional hernia, and risk factors for developing incisional hernia were evaluated. RESULTS: An incisional hernia developed in 44 of 173 (25.4%) patients after LDLT. Incisional hernia repair was performed in 14 of 173 patients (8.1%) who underwent LDLT from October 2006 to January 2010. Relaparatomy was associated with incisional hernia (p = 0.0002). The mean age at the time of the incisional hernia repair was 51 years, and 79% of the patients were men. The median follow-up period was 19.2 (13-36) months after the hernia repair. Three patients with intestinal incarceration underwent emergency surgery to repair the hernia. Partial small bowel resection was required in one patient. Postoperative complications included seroma formation in one patient and wound infection in another. There was no recurrence of hernia during the follow-up period. CONCLUSIONS: The incidence of incisional hernia after LDLT was 25.4% in this study. Relaparatomy increases the probability of developing incisional hernia in recipients of LDLT. According to the results of the study, repair of an incisional hernia with onlay mesh is a suitable option.

Retrohepatic inferior vena cava reconstruction with saphenous vein patch in advanced stage cholangiocarcinoma.

Hepatic resection is the only known curative treatment option in primary and metastatic liver tumors. Unlike other types of malignancies, the response rate to even the best chemotherapy protocols is quite low in liver malignancies. Survival is expressed in months in untreated liver malignancies or in patients with residual tumor after resection. The optimal survival can be achieved only by liver resection with negative surgical margins. In order to increase the number of patients suitable for hepatic resection, techniques such as portal vein embolization, neoadjuvant chemotherapy, two-step hepatectomy, re-do hepatectomy, hypothermic liver perfusion have been developed and newer modalities are still being investigated. Primary liver malignancies like hepatocellular carcinoma and cholangiocarcinoma, and metastatic liver tumors can invade the retrohepatic vena cava due to anatomical proximity. Invasion of either the hepatocaval confluence or vena cava are often considered as contraindications for liver resection due to the risk of intraoperative massive air embolism or hemorrhage. In this article, we present a patient who underwent left hepatectomy together with vena cava resection and reconstruction with saphenous vein patch due to cholangiocarcinoma.

Effects of Peroperative Cold Ischemia Time and Anhepatic Phase in Adult Living Donor Liver Transplant Recipients: Operation Time That is Not Affected by the Anhepatic Phase But is Prolonged by Cold Ischemia Time.

OBJECTIVE: It was aimed to examine the overall role of cold ischemia time and anhepatic phase durations in terms of peroperative blood transfusion needs, hospital stay conditions and postoperative charges, and survival in recipients. MATERIAL AND METHODS: One hundred forty-eight adult living donor liver transplant recipients (18 years and older) were included in the study. Whether the anhepatic phase and cold ischemia duration have an effect on the rates of surgery time, blood product transfusion, total hospital and intensive care unit stay, postoperative biliary complications, hepatic vein thrombosis, portal vein thrombosis, early postoperative bleeding, sepsis, and primary graft dysfunction. Was analyzed statistically. In addition, the effect of the anhepatic phase and cold ischemia time on graft survival was statistically examined by creating an average of the patient follow-up period. RESULTS: It was observed that the operation time increased statistically as the cold ischemia time increased (P = .000). No statistically significant relationship was found between other findings and cold ischemia time and anhepatic phase. CONCLUSION: Prolonged surgery time due to increased cold ischemia time may be an important finding in terms of peroperative and postoperative results of the graft.

Single-center analysis of the first 304 living-donor liver transplantations in 3 years.

BACKGROUND/AIMS: Living donor liver transplantations (LDLT) is a definitive treatment for patients with end-stage liver disease (ESLD), especially in the countries with donation problem. Between April 2007 and April 2010, we performed LDLT in 289 patients. Fifteen of the cases required re-transplantations. This study evaluates these 304 consecutive LDLTs donor and recipient outcomes. METHODOLOGY: Complication rates and survival data of the recipients and donors of 304 LDLT cases were analyzed. RESULTS: All donors are alive and well. Overall complication rate was 27%. Early postoperative recipient complication rate was 51%. Most frequent complication was infection. In the long-term there were 57 biliary stricture and 5 chronic bile fistula cases. Chronic and acute rejection attacks developed in 7 and 103 patients, respectively. Hepatic artery thrombosis rate was 8%. One, two and three year survival rates were 82%, 79% and 75%, respectively. Recipient mortality was 25%, mostly due to vascular complications, septic complications, liver dysfunction and chronic rejection. CONCLUSIONS: More than 150 liver tranplantations per year in a single center is a challenge in Turkey, where there is a shortage of deceased donor grafts. LDLT is a safe procedure for donors and effective for ESLD. Improvement in surgical technique would provide better outcomes.

A Single-Center's Early Surgical Outcomes of Living Donor Liver Transplantation.

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.

Conversion to Stoppa procedure in laparoscopic totally extraperitoneal inguinal hernia repair.

BACKGROUND AND OBJECTIVES: Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. METHODS: Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated. RESULTS: In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries. CONCLUSION: Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy.

Tissue Heavy Metals in Liver Diseases.

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.

Living donor liver transplantation for acute liver failure in pediatric patients caused by the ingestion of fireworks containing yellow phosphorus.

Yellow phosphorus is a protoplasmic toxicant that targets the liver. The ingestion of fireworks containing yellow phosphorus, either by children who accidentally consume them or by adults who are attempting suicide, often results in death due to acute liver failure (ALF). We present the outcomes of 10 children who ingested fireworks containing yellow phosphorus. There were 6 boys and 4 girls, and their ages ranged from 21 to 60 months. One patient remained stable without liver complications and was discharged. Three patients died of hepatorenal failure and cardiovascular collapse, and living donor liver transplantation (LDLT) was performed for 6 patients. The patients had grade II or III encephalopathy, a mean alanine aminotransferase level of 1148.2 IU/L, a mean aspartate aminotransferase level of 1437.5 IU/L, a mean total bilirubin level of 6.9 mg/dL, a mean international normalized ratio of 6.6, a mean Pediatric End-Stage Liver Disease score of 33.7, and a mean Child-Pugh score of 11.3. Postoperatively, 2 patients had persistent encephalopathy and died on the second or third postoperative day, and 1 patient died of cardiac arrest on the first postoperative day despite a well-functioning graft. The other 3 patients were still alive at a mean of 204 days. In conclusion, the ingestion of fireworks containing yellow phosphorus causes ALF with a high mortality rate. When signs of irreversible ALF are detected, emergency LDLT should be considered as a lifesaving procedure; however, if yellow phosphorus toxicity affects both the brain and the heart in addition to the liver, the mortality rate remains very high despite liver transplantation.

The short-term effects of low-level laser therapy in the management of breast-cancer-related lymphedema.

BACKGROUND: Breast-cancer-related lymphedema (BCRL) is a chronic disease, and currently there is no definitive treatment for it. There are some therapeutic interventions targeted to decrease the limb swelling and the associated problems. Low-level laser therapy (LLLT) has been used in the treatment of post-mastectomy lymphedema since 2007 in the US. The aim of this study is to review our short-term experience with LLLT in the treatment of BCRL. METHOD: Seventeen BCRL patients referred to our lymphedema program between 2007 and 2009 were enrolled in this study. All patients had experienced at least one conventional treatment modality such as complex physical therapy, manual lymphatic drainage, and/or pneumatic pump therapy. LLLT was added to patients' ongoing therapeutic regimen. All patients completed the full course of LLLT consisting of two cycles. The difference between sums of the circumferences of both affected and unaffected arms (ΔC), pain score, scar mobility, and range of motion were measured before and after first and second cycles of LLLT sequentially. RESULTS: All patients were female with a median age of 51.8 (44-64) years. ΔC decreased 54% (15-85%) and 73% (33-100%), after the first and second cycles of LLLT, respectively. Fourteen out of seventeen experienced decreased pain with motion by an average of 40% (0-85%) and 62.7% (0-100%) after the first and second cycle of LLLT, respectively. Three patients had no improvement in pain after LLLT. Scar mobility increased in 13 (76.4%) and shoulder range of motion improved in 14 (82.3%) patients after LLLT. One patient developed cellulitis during LLLT. CONCLUSION: Patients with BCRL received additional benefits from LLLT when used in conjunction with standard lymphedema treatment. These benefits include reduction in limb circumference, pain, increase in range of motion and scar mobility. Additionally, two cycles of LLLT were found to be superior to one in this study.

Acute traumatic diaphragmatic ruptures: A retrospective study of 48 cases.

PURPOSE: Traumatic diaphragmatic rupture (TDR) is associated with high rates of morbidity and mortality, and the preoperative diagnosis is difficult. METHODS: Forty-eight patients with TDR were treated in our department between January 2000 and May 2009. The cause, location, size of rupture, associated morbidity and mortality, surgical material for repair, and predictive factors for overall outcome were evaluated. RESULTS: There were 41 male patients (85%) and 7 female patients (15%) with a mean age of 33.8 years (range 17-69 years). Blunt trauma accounted for the injuries of 15 patients (31%) and 33 patients (68%) had penetrating injuries. The diagnosis was preoperatively established in 12 patients (25%) with a plain chest X-ray or/and computed tomography. The location of rupture was on the left side of the diaphragm in 35 patients (73%), on the right side in 10 (21%), and was bilateral in 3 patients (6%). Traumatic diaphragmatic rupture was repaired with interrupted nonabsorbable sutures or polypropylene mesh (8 patients). Postoperative complications were observed in 18 patients (38%). Overall mortality was observed in 7 patients (15%). The mortality was associated with hemorrhagic shock (P = 0.002), a high injury severity score (P = 0.002), and having additional injuries (P = 0.015). CONCLUSION: The outcome of the patients is associated with presence of hemorrhagic shock, a high injury severity score, and additional organ injury.

The effect of melatonin against FK506-induced renal oxidative stress in rats.

BACKGROUND: Nephrotoxicity is an important side effect of FK506 and oxidative stress has been considered as one of the possible mechanisms. The present investigation examines the ability of melatonin to protect against FK506-induced renal oxidative stress. METHODS: Thirty rats were divided into 3 groups (n = 10 each group). Group A was the sham group. Group B received 14 days FK506 (5 mg/kg/d, intraperitoneally [i.p.]) and group C received FK506 (5 mg/kg/d, i.p.) together with melatonin (4 mg/kg, i.p.) for 14 days. Kidney tissues were harvested to determine the tissue levels of malondialdehyde (MDA), total nitrite and nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). RESULTS: In group C, the levels of TNF-α, IL-6, and NO were lower than in the group B (P < .01, P < .03, and P < .04, respectively) and although MDA levels were lower than in group B, the differences were not statistically significant (P > .05). CONCLUSION: These results suggest that melatonin has protective effect against FK506-induced renal oxidative stress.

Comparison of Two Pancreatic Anastomosis Techniques in terms of Postoperative Complications After Pancreaticoduodenectomy.

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.

What Should Be the Rules for Downstaging for Hepatocellular Carcinoma?

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.

Risk factors for postoperative ileus following loop ileostomy closure.

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.

Is right lobe liver graft without main right hepatic vein suitable for living donor liver transplantation?

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.

Liver Transplantation for Hepatocellular Carcinoma: Malatya Experience and Proposals for Expanded Criteria.

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.
