Groundbreaking Dual-Graft Living Donor Liver Transplant Utilizing Full Right and Left Lateral Lobe Grafts: A Landmark Debut in the Kingdom of Saudi Arabia.

We introduce and documentthe first case of dual-graft living donor liver transplant, at the King Fahad Specialist Hospital in Dammam, Kingdom of Saudi Arabia, in which both a full right lobe and a left lateral segment graft were used. Our patient, a 63-year-old male, was diagnosed with nonalcoholic steatohepatitis cirrhosis and hepatocellular carcinoma involving segment 7 and selected for living donor liver transplant. Donor selection, graft volume assessment, surgical planning, procurement, and implantation of the dual grafts were meticulously executed. The first donor had an estimated right lobe volume of 639 mL, yielding an estimated graft-to-recipient weight ratio of 0.68. A liver biopsy revealed 3% macrosteatosis.The second donor's contribution comprised a left lateral segment volume of 280 mL.The decision was made for dual-graft liver transplant. With both grafts, the volume totaled 919 mL, representing graft-torecipient weight ratio of 0.98. Surgical techniques involved anastomoses of hepatic veins, portal veins, arteries, and biliary reconstruction. Both donors and the recipient were closely monitored posttransplant. After the procedure, both donors recovered swiftly and were discharged 4 days postoperation. The recipient experienced a smooth postoperative course, spending 4 days in the intensive care unit and discharged on day 26 posttransplant. This pioneering dual-graft living donor liver transplant showed successful outcomes and highlighted the potential of this approach to expand the limited donor pool, particularly in regions relying predominantly on living donors, like Saudi Arabia. This innovative surgical technique offers a promising solution to address the growing demand for liver transplants while ensuring safety for individual donors and maintaining acceptable recipient outcomes. Further exploration and adoption of dual-graft liver transplant could significantly affectthe field of livertransplant globally.

Resource utilization in management of spontaneous intracerebral hemorrhage without systemic risk factors. Does early surgical decompression matter?

BACKGROUND: Even though different subtypes of spontaneous ICH are frequently linked to a poor prognosis, their causes, pathological features, and prognoses vary. Atypical intracerebral hemorrhage is the subtype of spontaneous ICH that usually occurs due to an underlying localized vascular lesion. It is unrelated to systemic vascular risk factors, mostly affects children and young adults and is associated with a relatively good outcome. This fact should be considered when planning the evaluation and treatment. Investigating the cause of this subtype is fundamental to providing optimal management. However, if resources do not allow completing the investigations, the cause will be more difficult to discover. Treatment decisions will be made under stress to save the patient's life, especially with rapidly deteriorating patients. METHODS: We described three cases of spontaneous ICH without systemic risk factors where the bleeding source could not be determined before surgery due to a lack of resources, preventing preoperative vascular investigation. Knowing that the atypical ICH has a distinct identity, regarding etiology and prognosis, encouraged the surgeons to resort to early surgical decompression as an alternative plan. We reviewed the literature searching for supporting evidence. RESULTS: The results of treatment of the presented cases were satisfactory. The lack of reported similar cases was brought to light by a literature analysis that sought to provide backing for the proposed management strategy. In the end, we supplied two graphic organizers to help readers remember the different types and treatment of hemorrhagic stroke. CONCLUSION: There isn't enough evidence to show that there are other ways to treat atypical intracerebral haemorrhage when resources are limited. The presented cases highlight the importance of decisionmaking in resource-constrained situations when patient outcomes can be improved.

Posterior component separation with transversus abdominis muscle release versus mesh-only repair in the treatment of complex ventral-wall hernia: a randomized controlled trial.

BACKGROUND: Complex ventral hernias (VHs) represent a real challenge to both general and plastic surgeons. This study aims to compare Sublay Mesh-Only Repair to Posterior Component Separation "PCS" with Transversus Abdominis Release "TAR" in the treatment of complex ventral-wall hernias (VHs). METHODS: This a randomized, controlled, intervention, including two parallel groups: A; Sublay Mesh-Only Repair and Group B; "TAR". Consecutive patients of both genders aged between 18 and 65 years old with complex VHs presented at Mansoura University Hospitals including large-sized abdominal-wall hernia ≥ 10 cm in width, loss of domain ≥ 20%, multiple hernial defects, or recurrent hernias. Immuno-compromised patients, patients with liver impairment, or severe heart failure were considered an exclusion criterion. The primary outcome is the recurrence rate after 12-months following the procedure. RESULTS: Fifty-six patients were recruited in this study. There was no significant difference between both groups regarding recurrence. However, there was significant differences between both groups regarding seroma favoring mesh-only repair. CONCLUSIONS: Although TAR may be associated with longer operative times and more blood losses, these were not found to be statistically significant. Postoperative complication, except for seroma, and recurrence rates were comparable in both groups. Trail registration The study was registered on clicaltrials.gov "NCT04516031".

Oncocytoid Variant of High-Grade Salivary Duct Carcinoma: A Potential Diagnostic Pitfall. A Report on Two Patients.

Salivary duct carcinoma (SDC) is an uncommon and aggressive salivary malignancy. The oncocytoid variant of salivary duct carcinoma (OSDC) has only been reported in the English literature once before. Here we detail two new patients. A 71-year-old female presented with a painless enlarging left parotid mass. Imaging and fine-needle aspiration were nondiagnostic. The second patient, a 79-year-old male, presented with painless swelling in the right cheek. Imaging was nondiagnostic. Both patients underwent surgical resection. Histopathology revealed bland yet infiltrative OSDC in both cases. These tumors were AR+ (androgen receptor) by immunohistochemistry. Potential difficulty exists in distinguishing the oncocytoid variant of SDC, a rare and relatively bland tumor, from oncocytoma, a more commonly encountered entity. AR expression can aid in the correct diagnosis.

The management of asymptomatic radiological anastomotic leakage following anterior resection.

BACKGROUND: The evidence to guide the management of asymptomatic radiologically-detected anastomotic leakages (ARAL) following anterior resection (AR) with diverting ileostomy is deficient. This study describes the outcomes of managing ARAL one of the UK teaching hospitals. METHOD: The study included all patients diagnosed with ARAL following AR during 8 years period (2012-2020). The following data were retrospectively collected: patient demographics, surgical indication, anastomotic technique, tumour staging, neoadjuvant therapy, how ARAL was managed, the outcomes and duration to heal and ileostomy reversal. RESULTS: A total of 35 patients (M = 24) who developed ARAL during the study period were included. In 32 patients, AR was performed for rectal cancer. All patients with ARAL were treated conservatively and in 31 (89%) patients, there was complete resolution of the leakage within a median duration of 6 months. Covering loop ileostomies were reversed in 26 (74%) patients with a median interval to reversal of 10 months. CONCLUSION: Most asymptomatic radiologically-detected anastomotic leakages after anterior resection heal with conservative treatment in the presence of a covering loop ileostomy with an expected average delay of 6 months for the leakage to heal before covering ileostomies can be reversed.

The impact of Oncotype DX testing on adjuvant chemotherapy decision making in 1-3 node positive breast cancer.

BACKGROUND: Oncotype DX testing has reduced the use of adjuvant chemotherapy in node-negative early breast cancer but less is known about its impact in node positive patients. AIM: This study aimed to investigate the impact of Oncotype DX gene assay testing on the decision to offer adjuvant chemotherapy in oestrogen positive, human epidermal growth factor receptor 2 negative, 1-3 lymph node positive patients. METHODS: Retrospective review of all node positive patients who underwent Oncotype DX testing at a single centre. Clinicopathological data, as well as estimated survival benefit data (from the PREDICT tool), was evaluated by a multidisciplinary group of surgeons and oncologists. Treatment decisions based on clinicopathological data were compared to recurrence scores (RS). A cut off RS > 30 was used to offer adjuvant chemotherapy. RESULTS: The 69 patients were identified, of which 9 (13%) had an RS > 30 and assigned a high-genomic risk of recurrence. The 32 patients (46.4%) were offered adjuvant chemotherapy. Overall based on the use of the RS, the decision to offer adjuvant chemotherapy changed in 36% of patients, and ultimately 24 patients (34.7%) would have been spared chemotherapy. CONCLUSION: Using clinicopathological data alone to make decisions regarding adjuvant chemotherapy in node positive breast cancer leads to overtreatment. Additional information on tumour biology as assessed by the Oncotype DX RS helps to select those patients who will benefit from adjuvant chemotherapy and spare patients from unnecessary chemotherapy.

Management of anastomotic leaks after elective colorectal resections: The East of England experience. A retrospective cohort.

INTRODUCTION: Colorectal anastomotic leaks (AL) are associated with high morbidity and mortality. Management of AL and its intra-operative decision making is often difficult. The aim of this multi-centre study is to explore different management strategies, including different surgical options, and analyse rates and patterns of failure of initial management. METHODS: All consecutive patients who had a confirmed AL after elective colorectal resections from 1st January 2014 to 31st December 2019 were included at seven hospitals across the East of England Region. Morbidity (length of stay, and failures) and mortality were compared across the different management strategies, and survival analyses were performed (Clinicaltrials.gov ID: NCT05000580). RESULTS: Across all seven hospitals, a total of 3391 elective resection were done during the study period. 201 (5.9%) consecutive patients with confirmed AL were included. The initial treatment was conservative in 102(50.7%). 19 patients (9.5%) had a radiological procedure, 80 (39.8%) of patients required surgery as an initial treatment post AL. Of those who initially did not have a surgical intervention (n = 121), 10% (n = 12/121) eventually required laparotomy, 2 additional patients required transanal drainage. Ultimately 45.8% (n = 92/201) of the whole population eventually required a laparotomy. Patients managed conservatively had a shorter LOS when compared to either radiological drainage or surgical patients. Patients with a defunctioning stoma are more likely to have a successful conservative management and shorter LOS. 90-day mortality across the entire population was 8.1%. There were no significant differences in mortality or long-terms survival between the different initial treatment modalities or whether the leak was right or left sided. CONCLUSION: Despite initial conservative, antibiotic and radiological intervention being successful in the majority of patients, two out of five patients will still require a laparotomy and over a quarter of patients will have an end stoma.

Isolation and Identification of Pathogenic Acanthamoeba Species from Air Conditioning Systems, Egypt.

Acanthamoeba are free-living amoebae that cause granulomatous amoebic encephalitis and keratitis. In this study, we aimed to isolate and identify Acanthamoeba from air conditioning systems using in vitro cell culture and polymerase chain reaction assays. We also estimated the pathogenicity of the isolates by measuring their thermotolerance and studying mice models inoculated with these isolates. Of the 80 dust samples acquired, 41 (51.25%) were found to be positive for Acanthamoeba spp. using in vitro cell culture and the results were validated using PCR. Out of these 41 samples, 27 (65.9%) were thermotolerant and 16 (39%) samples could infect mice and cause histopathological effects. Highly pathogenic Acanthamoeba isolates were characterized by their thermotolerance and the ability to disseminate in all organs after infection, causing early death of infected animals. Our study thus validated the presence of pathogenic isolates of Acanthamoeba in air conditioners that may be potentially infectious to humans.

Real-world use of workplace based assessments in surgical training: A UK nationwide cross-sectional exploration of trainee perspectives and consensus recommendations from the Association of Surgeons in Training.

BACKGROUND: Despite widespread uptake, the utility of Workplace Based Assessments (WBAs) is disputed and evidence underpinning their use is largely based upon their completion in ideal conditions, rather than the real-world setting. AIM: To ascertain the real-world usage of WBAs, as perceived by UK surgical trainees. MATERIALS AND METHODS: An anonymous online questionnaire conducted nationally via the Association of Surgeons in Training (ASiT). Evaluation of 906 completed trainee responses, across all surgical specialties and training levels, employed mixed methods to interpret quantitative and qualitative data. RESULTS: The sample permitted a 3.0% confidence level with acceptable internal consistency (Cronbach's alpha 0.755). Formative use was supported by 72.5% and summative use was rejected by almost as many (66.3%). WBA use was perceived to deviate markedly from that recommended by the Joint Committee on Surgical Training (JCST). Significant misuse was identified and elements perceived as inaccurate appear commonplace across the breadth of surgical specialties. Inaccurate completion was acknowledged by 89.6% of respondents and some trainers appear complicit, 147 individuals (16.2%) having reported this to trainers, 40.9% aware of 'unobserved sign-off', and 33.6% aware of 'password disclosure' by trainers. Furthermore, a majority of trainees felt the Annual Review of Competency Progression (ARCP) respected WBA quantity above quality (55.4%), and a third felt pressure to overstate the number completed (32.0%). Reasons for misuse appeared largely centred upon time restraints, lack of engagement and a will to achieve the required targets for career progression. 1.5 CONCLUSIONS: This study demonstrates that UK surgical trainees perceive that most trainees deviate from guidance in their use of WBAs. This is worrying in both the apparent frequency and nature of misuse and somewhat undermines existing evidence for their role in surgical training. Trainees perceive that required numbers of WBAs are too high, that training programmes fail to encourage their use as formative assessments, and that there is a lack of engagement by many trainees and trainers. We present consensus recommendations from ASiT for the improvement of WBA use in UK surgical training.

Development and external validation of a prediction model for survival in patients with resected ampullary adenocarcinoma.

INTRODUCTION: Ampullary adenocarcinoma (AAC) is a rare malignancy with great morphological heterogeneity, which complicates the prediction of survival and, therefore, clinical decision-making. The aim of this study was to develop and externally validate a prediction model for survival after resection of AAC. MATERIALS AND METHODS: An international multicenter cohort study was conducted, including patients who underwent pancreatoduodenectomy for AAC (2006-2017) from 27 centers in 10 countries spanning three continents. A derivation and validation cohort were separately collected. Predictors were selected from the derivation cohort using a LASSO Cox proportional hazards model. A nomogram was created based on shrunk coefficients. Model performance was assessed in the derivation cohort and subsequently in the validation cohort, by calibration plots and Uno's C-statistic. Four risk groups were created based on quartiles of the nomogram score. RESULTS: Overall, 1007 patients were available for development of the model. Predictors in the final Cox model included age, resection margin, tumor differentiation, pathological T stage and N stage (8th AJCC edition). Internal cross-validation demonstrated a C-statistic of 0.75 (95% CI 0.73-0.77). External validation in a cohort of 462 patients demonstrated a C-statistic of 0.77 (95% CI 0.73-0.81). A nomogram for the prediction of 3- and 5-year survival was created. The four risk groups showed significantly different 5-year survival rates (81%, 57%, 22% and 14%, p < 0.001). Only in the very-high risk group was adjuvant chemotherapy associated with an improved overall survival. CONCLUSION: A prediction model for survival after curative resection of AAC was developed and externally validated. The model is easily available online via www.pancreascalculator.com.

The Role of Polypropylene Microfibers in Thermal Properties and Post-Heating Behavior of Cementitious Composites.

This paper experimentally studied the effect of polypropylene (PP) microfibers on thermal and post-heating mechanical behaviors of cementitious composites. Cement mortars with small dosage of polypropylene fibers were prepared, heated at various temperatures (150 °C, 200 °C, 450 °C, and 600 °C), and then tested. The investigated parameters include residual compressive and flexural strengths, elastic modulus, fracture energy, stress intensity factors, failure modes, microstructure (scanning electron microscopy (SEM) imaging), thermal conductivity, heat flow (differential scanning calorimetry (DSC) test), mass loss (thermogravimetric analysis (TGA) test), and chemical composition (XRD analysis). The results showed the efficiency of PP fibers to enhance the post-heating behavior and the residual mechanical properties of cement mortar after heating. The presence of PP fibers did not affect the heat flow and the mass loss of cement mortar at room temperature. However, heating cement mortar at temperature beyond the melting point of the fibers negatively affected its thermal behavior. The presence of PP fibers played a major role in bridging the cracks and mitigating their propagation. Once the melting point of the polypropylene fibers is exceeded, the fibers melted and created extra voids in the microstructure of concrete.

Changes on physicochemical and rheological properties of biscuits substituted with the peel and alcohol-insoluble solids (AIS) from cactus pear (Opuntia ficus-indica).

Cactus pear fruit consists of the peel, seeds and pulp. The peel is a major waste in cactus pear pulp based products accounting about 37.72% of the fruit weight. The aim of this study was to utilized and characterized the physicochemical and rheological properties of biscuits substituted with extracted cactus pear peel (CPP) and alcohol-insoluble solids (AIS) from cactus pear (Opuntia ficus-indica). To prepare AIS, peels were shredded and dropped in ethanol (70%) for 15 min. The mixture was boiled at 70 °C for 30 min, filtered and washed with ethanol 70% and the washing repeated until no sugars. The residue was washed and dried at room temperature. Changes in physiochemical and rheological properties of extracted CPP and AIS from cactus pear to qualify determine their use in the production of them to produce a fiber-rich food product. The water-holding capacity was 3.7 ml/g for the peel and 1.5 ml/g for the AIS, and the oil-holding capacity was approximately the same for both the CPP and AIS. The protein content was 3.5% for the CPP and 3.72% for the AIS. The CPP and AIS contained little fat (1.22% and 1.44%, respectively). Potassium and calcium in the AIS had the highest concentration, at 21.49 g/kg and 44.04 g/kg, respectively, and these minerals were found at 22.07 g/kg and 16.66 g/kg, respectively, in the CPP. The dominant phenolic compounds found in the CPP were pyrogallol, catechol, catechin, and alpha-coumaric acid. The results showed that the AIS contained pyrogallol (61.67 ppm), benzoic acid (10.68 ppm), vanillic acid (7.66 ppm), catechin (4.65 ppm) and salicylic acid (4.51 ppm). The CPP was rich in glucose (25.95%) and fructose (21.36%) compared to the AIS. The sensory evaluation indicated that 7.5% dried cactus pear peel or 7.5% AIS can be successfully used in substitution of wheat flour biscuits. It could be conducted cactus pear as major by-product can be important for the industrial utilization.

Telomere Trimming and DNA Damage as Signatures of High Risk Neuroblastoma.

Telomeres play important roles in genome stability and cell proliferation. High risk neuroblastoma (HRNB), an aggressive childhood cancer, is especially reliant on telomere maintenance. Three recurrent genetic aberrations in HRNB (MYCN amplification, TERT re-arrangements, and ATRX mutations) are mutually exclusive and each capable of promoting telomere maintenance mechanisms (i.e., through telomerase or ALT). We analyzed a panel of 5 representative HRNB cell lines and 30 HRNB surgical samples using assays that assess average telomere lengths, length distribution patterns, single-stranded DNA on the G- and C-strand, as well as extra-chromosomal circular telomeres. Our analysis pointed to substantial and variable degrees of telomere DNA damage in HRNB, including pervasive oxidative lesions. Moreover, unlike other cancers, neuroblastoma consistently harbored high levels of C-strand ssDNA overhangs and t-circles, which are consistent with active "telomere trimming". This feature is observed in both telomerase- and ALT-positive tumors and irrespective of telomere length distribution. Moreover, evidence for telomere trimming was detected in normal neural tissues, raising the possibility that TMMs in HRNB evolved in the face of a canonical developmental program of telomere shortening. Telomere trimming by itself appears to distinguish neuroectodermal derived tumors from other human cancers, a distinguishing characteristic with both biologic and therapeutic implications.

Cholecystolithotomy, a new approach to reduce recurrent gallstone ileus.

The incidence of gallstone ileus (GSI) is increasing. Current treatment options include enterolithotomy with or without cholecystectomy and repair of the biliodigestive fistula. Although most surgeons defer the management of the biliodigestive fistula to avoid the associated morbidity and mortality, this can lead to increased rate of recurrence of GSI by the remaining gallstones. More than 130 cases of recurrent GSI were reported in published works, and the incidence of recurrent GSI is reported to be between 5% and 20%. Some cases of second recurrent attacks have also been reported. Most cases were reported in elderly women with faceted stones during the first 2 months from the first episode of GSI. This article reviews the current treatment options for more than 4,300 reported cases of GSI. A treatment algorithm is recommended based on the severity of the inflammation around the gallbladder, including cholecystolithotomy as a third treatment approach that aims to reduce the risk of recurrent GSI.

FDA-approved ferumoxytol displays anti-leukaemia efficacy against cells with low ferroportin levels.

Acute myeloid leukaemia is a fatal disease for most patients. We have found that ferumoxytol (Feraheme), an FDA-approved iron oxide nanoparticle for iron deficiency treatment, demonstrates an anti-leukaemia effect in vitro and in vivo. Using leukaemia cell lines and primary acute myeloid leukaemia patient samples, we show that low expression of the iron exporter ferroportin results in a susceptibility of these cells via an increase in intracellular iron from ferumoxytol. The reactive oxygen species produced by free ferrous iron lead to increased oxidative stress and cell death. Ferumoxytol treatment results in a significant reduction of disease burden in a murine leukaemia model and patient-derived xenotransplants bearing leukaemia cells with low ferroportin expression. Our findings show how a clinical nanoparticle previously considered largely biologically inert could be rapidly incorporated into clinical trials for patients with leukaemia with low ferroportin levels.

Assessment of Eco-friendly Gases for Electrical Insulation to Replace the Most Potent Industrial Greenhouse Gas SF6.

Gases for electrical insulation are essential for the operation of electric power equipment. This Review gives a brief history of gaseous insulation that involved the emergence of the most potent industrial greenhouse gas known today, namely sulfur hexafluoride. SF6 paved the way to space-saving equipment for the transmission and distribution of electrical energy. Its ever-rising usage in the electrical grid also played a decisive role in the continuous increase of atmospheric SF6 abundance over the last decades. This Review broadly covers the environmental concerns related to SF6 emissions and assesses the latest generation of eco-friendly replacement gases. They offer great potential for reducing greenhouse gas emissions from electrical equipment but at the same time involve technical trade-offs. The rumors of one or the other being superior seem premature, in particular because of the lack of dielectric, environmental, and chemical information for these relatively novel compounds and their dissociation products during operation.

A wandering folded liver displaced by the distended bowel: a new case report with review of the literature.

INTRODUCTION: The wandering liver is an extremely rare condition in which the liver moves significantly or 'wander' with changes in patient's lie. This is believed to be an acquired condition perhaps precipitated by persistent congenital ventral mesogastrium which acts as an axis or a mesentery for the liver to rotate. The vast majority of reported cases were associated with other chronic abnormalities of the gastrointestinal tract, especially sigmoid volvulus. PATIENTS AND METHODS: We present a case report of an acquired isolated transposition of the liver with a review of the English-language literature of wandering liver in adults and paediatric age group. RESULTS AND CONCLUSIONS: The clinical presentation of wandering liver is variable. Most of the reported cases were asymptomatic and are usually diagnosed while having investigation or surgery for other reasons, especially the commonly associated bowel problems. However, some patients may present with intermittent jaundice and abdominal pain secondary to the abnormal liver configuration. Due to the scarcity of the condition, the diagnosis can be challenging and improper concerns of permanent liver failure is possible. Hepatopexy is usually required for symptomatic patients with good results.

Financial Burden Secondary to Delay in Cholecystectomy Following Mild Biliary Pancreatitis.

AIM OF THE STUDY: The guidelines recommend that patients with mild gallstones pancreatitis should undergo a definitive management for gallstones during the same admission or within the next two weeks. The aim of this study was to estimate the financial cost resulting from a delay in surgical management following mild gallstones pancreatitis. This includes the costs of readmissions with biliary events and the subsequent investigations required during these admissions. MATERIALS AND METHODS: A retrospective analysis included patients with gallstone pancreatitis who were admitted to a district general hospital in the United Kingdom over one year. Patients with severe pancreatitis and those unfit for surgery were excluded. RESULTS: Forty patients were included in the study, 27 females (67%) and 13 males (33%). Mean age was 50.2 years. Twenty-two patients of the total presented with a single admission with gallstone pancreatitis prior to an elective surgery; however, 18 patients (45%) required recurrent admissions. The duration between the first admission and surgery ranged from 14 to 389 days (median of 99 days). Only one patient (2.5%) had cholecystectomy within two weeks of admission as per guidelines. Twenty-two ultrasound scans, four computed tomography scans, 15 magnetic resonance cholangiopancreatography, and two endoscopic retrograde cholangiopancreatography were the total of the extra-investigations required during readmissions. Estimated costs of extra admissions and extra investigations exceeded £33,000. CONCLUSIONS: The delay in cholecystectomy for patients admitted with mild gallstone pancreatitis and fit for surgery has resulted in high readmission rate with biliary events, and subsequently high extrax costs.

Living donor hepatectomy (LDH)--comparative study between two different anesthetic techniques.

BACKGROUND: Living donor hepatectomy (LDH) is now widely used to meet the need for liver grafts due to the shortage of cadaveric livers. Donor safety and perioperative anesthetic management are our major concern. The aim of our study was to compare two anesthetic techniques for management of living donor hepatectomy. PATIENTS & METHODS: After ethical committee approval and informed written consent, 20 donors ASA I physical status undergoing hepatectomy for living-relative liver transplant were allocated randomly to one of two groups. Group A where anesthesia was induced with fentanyl 2 microg/kg and propofol 2-3 mg/kg(-1), and maintained with isoflurane 0.8-1.2% and fentanyl infusion 1-2mcg/kg(-1)/h(-1). In group B anesthesia was induced with sufentanyl 0.2mcg/kg(-1), and propofol 2-3mg/kg(-1), and maintained with propofol infusion 6-12 mg/kg(-1)/h(-1), and sufentanyl infusion 0.2-0.4mcg/kg(-1)/h(-1). Atracurium was the muscle relaxant for intubation and maintenance in both groups. RESULTS: There were no perioperative mortality in both groups, no significant statistical differences between both groups as regard demographic data, duration of surgery, duration of anesthesia, hospital stay, intraoperative hemodynamics, blood loss, liver function tests (PT, AST, & ALT) measured in the first, third, and seventh days postoperative. CONCLUSION: In conclusion, our study demonstrated that both anesthetic techniques were well tolerated for living donor hepatectomy, with no blood transfusion required, with short and safe discharge from PACU and short hospital stay, but with significant laboratory changes reflecting transient impairment in metabolic liver function. These procedures have proven useful as an important alternative to the cadaveric liver transplantation. Both techniques can be used as fast tract technique for living donor hepatectomy.
