RESUMO

INTRODUCTION: Surgical stabilization of rib fractures (SSRF) using standard rib plating systems has become a norm in developed countries. However, the procedure has not garnered much interest in low-middle-income countries, primarily because of the cost. METHODS: This was a single-center pilot randomized trial. Patients with severe rib fractures were randomized into two groups: SSRF and nonoperative management. SSRF arm patients underwent surgical fixation in addition to the tenets of nonoperative management. Low-cost materials like stainless steel wires and braided polyester sutures were used for fracture fixation. The primary outcome was to assess the duration of hospital stay. RESULTS: Twenty-two patients were randomized, 11 in each arm. Per-protocol analysis showed that the SSRF arm had significantly reduced duration of hospital stay (22.6 ± 19.1 d versus 7.9 ± 5.7 d, P value 0.031), serial pain scores at 48 h and 5 d (median score 5, IQR (3-6) versus median score 7, IQR (6.5-8), P value 0.004 at 48 h and median score 2 IQR (2-3) versus median score 7 IQR (4.5-7) P value 0.0005 at 5 d), significantly reduced need for injectable opioids (9.9 ± 3.8 mg versus 4.4 ± 3.4 mg, P value 0.003) and significantly more ventilator-free days (19.9 ± 8.7 d versus 26.4 ± 3.2 d, P value 0.04). There were no statistically significant differences in the total duration of ICU stay (median number of days 2, IQR 1-4.5 versus median number of days 7, IQR 1-14, P value 0.958), need for tracheostomy (36.4% versus 0%, P value 0.155), and pulmonary and pleural complications. CONCLUSIONS: SSRF with low-cost materials may provide benefits similar to standard rib plating systems and can be used safely in resource-poor settings.

RESUMO

Living donor liver transplantation (LDLT) needs "Mercedes Benz" or "J-shaped" incision, causing short and long-term complications. An upper midline incision (UMI) is less invasive alternative but technically challenging. Reporting UMI for recipients in LDLT vs. conventional J-shaped incision. Retrospective analysis, July 2021 to December 2022. Peri-operative details and post-transplant outcomes of 115 consecutive adult LDLT recipients transplanted with UMI compared with 140 recipients with J-shaped incision. Cohorts had similar preoperative and intraoperative variables. The UMI group had significant shorter time to ambulation (3 ± 1.6 vs. 3.6 ± 1.3 days, p = 0.001), ICU stay (3.8 ± 1.3 vs. 4.4 ± 1.5 days, p = 0.001), but a similar hospital stay (15.6±7.6 vs. 16.1±10.9 days, p = 0.677), lower incidence of pleural effusion (11.3% vs. 27.1% p = 0.002), and post-operative ileus (1.7% vs. 9.3% p = 0.011). The rates of graft dysfunction (4.3% vs. 8.5% p = 0.412), biliary complications (6.1% vs. 12.1% p = 0.099), 90-day mortality (7.8% vs. 12.1% p = 0.598) were similar. UMI-LDLT afforded benefits such as reduced pleuropulmonary complications, better early post-operative recovery and reduction in scar-related complaints in the medium-term. This is a safe, non-inferior and reproducible technique for LDLT.

RESUMO

BACKGROUND: Non-invasive tests (NITs) are useful to assess advanced fibrosis (AF) in nonalcoholic fatty liver disease (NAFLD). Data from Asian countries suggest that these tests have poor performance. We aimed to assess diagnostic accuracy of established thresholds of biomarker-based NITs and Transient Elastography (TE) in identifying AF and evaluated the utility of a two-step test approach. METHODS: Biopsy-proven 641 NAFLD patients (55.2% males, median age 42 years) were included from three different centers of Asia. AF (≥ F3) was identified as per histological staging (24.8%). RESULTS: TE had the highest area under the receiver operating characteristic curve (AUROC) 0.82 (0.79-0.86), and all other biomarker-based NITs had low AUROC (< 0.7). NITs performed poorly at established thresholds. The combination of NITs utilizing liver stiffness measurement (LSM) and biomarkers, Agile 3+ and FAST, demonstrated acceptable diagnostic accuracy (AUROC 0.82 and 0.78, respectively), but none were superior to LSM alone. LSM measured using appropriate M and XL probes remained accurate regardless of body mass index (BMI); NFS and APRI scores were less accurate at higher BMI ranges. A two-step approach using NFS rule-out criteria (< - 2.97 to rule out) followed by LSM (< 7.3 kPa to rule out and ≥ 12.7 kPa to rule in) correctly classified 62.4% of patients, with only 10.2% of patients incorrectly classified. CONCLUSION: NITs have not been validated to identify AF in the Asian NAFLD population, and internationally accepted thresholds yield high false-negative rates. LSM and LSM-based combination tests remain the most accurate.

RESUMO

INTRODUCTION: Recent literature on managing traumatic duodenal injuries suggests the superiority of primary repair. We hypothesized that duodenal trauma repair by primary closure might not be a safe strategy in an environment dealing predominantly blunt injuries with limited resources. METHODS: Data analysis was done from the prospectively maintained trauma registry. The study period chosen was from January 1, 2014 to December 31, 2018. Data of 63 patients were analyzed for demographics, injuries, management, and outcome. Logistic regression was used to identify mortality predictors. RESULTS: The most common mechanism of injury was blunt (56/63, 88.9%). Forty (63.5%) patients had associated intraabdominal injuries. The most common American Association for the Surgery of Trauma grade of injury to the duodenum was three in 21 patients. Univariate analysis showed that mortality was associated with hypotension on presentation, higher duodenal grade, associated abdominal vascular injuries, primary closure, and duodenal leak. Logistic regression showed associated associated abdominal vascular injuries, primary closure, and leak remained significant predictors of mortality. CONCLUSIONS: Primary repair was found to be an independent predictor of mortality. A patient's physiology is a critical determinant of the outcome. Liberal use of tube duodenostomy over primary repair seems reasonable for blunt duodenal injury management.

RESUMO

Conventional selection criteria for liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) are based on tumour size/number only, and do not consider vital surrogates of tumor biology such as alpha-fetoprotein (AFP) and tumor [18 F]fluorodeoxyglucose positron emission tomography ([18 F]FDG PET) avidity. We analyzed survival outcomes, and predictors of HCC recurrence in 405 patients with cirrhosis and HCC (HCC-cirr) who underwent living donor LT (LDLT) using our expanded selection criteria: no extrahepatic disease or major vascular invasion, irrespective of tumor size/number. Fifty-one percent patients had tumours beyond Milan, and 43% beyond the University of California San Francisco [UCSF] criteria. The 5-year overall survival (OS) and recurrence-free survival (RFS) were 64% and 70%, respectively. Three preoperatively available factors predicted recurrence: pre-LT AFP ≥100 ng/mL (P = 0.005; hazard ratio [HR], 2.190), tumor burden beyond the UCSF criteria (P = 0.001; HR, 2.640), and [18 F]FDG PET avidity (P = 0.004; HR, 2.442). A prognostic model based on the number and combination of the aforementioned preoperative risk factors was developed using a competing-risk RFS model. Three risk groups were identified: low (none or a single risk factor present, 9.3% recurrence), moderate (AFP ≥100 ng/mL and [18 F]FDG PET avidity, or beyond UCSF tumor and [18 F]FDG PET avidity, 25% recurrence), and high (AFP ≥100 ng/mL and beyond UCSF, or presence of all 3 risk factors, 46% recurrence). Acceptable long-term outcomes were achieved using our expanded selection criteria. Our prognostic model to predict recurrence based on preoperative biological and morphological factors could guide pretransplant management (downstaging versus upfront LDLT) with the aim of reducing post-LDLT recurrence.

RESUMO

BACKGROUND AND AIM: Type 2 diabetes (T2D) and low skeletal muscle mass (SMM) are associated with increased risk of nonalcoholic fatty liver disease (NAFLD). However, data regarding the association between low SMM and NAFLD-related liver fibrosis in individuals with T2D are scarce. Therefore, we aimed to investigate the association between low SMM and liver fibrosis in individuals with T2D and NAFLD. METHODS: Controlled attenuation parameter (CAP) of ≥ 248 dB/m was taken as cutoff suggesting NAFLD. Clinically relevant liver fibrosis and advanced liver fibrosis were defined as liver stiffness measurement (LSM) by transient elastography (TE) of ≥ 8.0 and ≥ 9.6 kPa, respectively. SMM was measured using dual energy X-ray absorptiometry (DEXA). Low SMM was defined as appendicular SMM index of < 7.0 kg/m2 for men and < 5.4 kg/m2 for women. RESULTS: Of the 487 consecutive patients with T2D, 366 (75.1%) had NAFLD. Among individuals with NAFLD, 118 (32.2%) and 64 (17.5%) had clinically relevant liver fibrosis and advanced liver fibrosis, respectively. Low SMM was diagnosed in 78 (21.3%) individuals with NAFLD. Patients with low SMM were older (56.1 vs 52.8 years) and had longer duration of diabetes (10.3 vs 8.1 years). Low SMM was an independent risk factor associated with clinically relevant liver fibrosis (P = 0.002) and advanced liver fibrosis (P ≤ 0.0001). Associations between low SMM and clinically relevant- and advanced liver fibrosis were maintained even after sequential adjustment for confounding variables through the multivariate regression analysis. CONCLUSIONS: Low SMM is independently associated with liver fibrosis in individuals with T2D and NAFLD.

RESUMO

AIMS/HYPOTHESIS: Liraglutide, a daily injectable glucagon-like peptide-1 receptor (GLP-1r) agonist, has been shown to reduce liver fat content (LFC) in humans. Data regarding the effect of dulaglutide, a once-weekly GLP-1r agonist, on human LFC are scarce. This study examined the effect of dulaglutide on LFC in individuals with type 2 diabetes and non-alcoholic fatty liver disease (NAFLD). METHODS: Effect of dulaglutide on liver fat (D-LIFT) was a 24 week, open-label, parallel-group, randomised controlled trial to determine the effect of dulaglutide on liver fat at a tertiary care centre in India. Adults (n = 64), who had type 2 diabetes and MRI-derived proton density fat fraction-assessed LFC of ≥6.0% at baseline, were randomly assigned to receive dulaglutide weekly for 24 weeks (add-on to usual care) or usual care, based on a predefined computer-generated number with a 1:1 allocation that was concealed using serially numbered, opaque, sealed envelopes. The primary endpoint was the difference of the change in LFC from 0 (baseline) to 24 weeks between groups. The secondary outcome measures included the difference of the change in pancreatic fat content (PFC), change in liver stiffness measurement (LSM in kPa) measured by vibration-controlled transient elastography, and change in liver enzymes. RESULTS: Eighty-eight patients were screened; 32 were randomly assigned to the dulaglutide group and 32 to the control group. Overall, 52 participants were included for per-protocol analysis: those who had MRI-PDFF data at baseline and week 24. Dulaglutide treatment resulted in a control-corrected absolute change in LFC of -3.5% (95% CI -6.6, -0.4; p = 0.025) and relative change of -26.4% (-44.2, -8.6; p = 0.004), corresponding to a 2.6-fold greater reduction. Dulaglutide-treated participants also showed a significant reduction in γ-glutamyl transpeptidase (GGT) levels (mean between-group difference -13.1 U/l [95% CI -24.4, -1.8]; p = 0.025) and non-significant reductions in aspartate aminotransferase (AST) (-9.3 U/l [-19.5, 1.0]; p = 0.075) and alanine aminotransferase (ALT) levels (-13.1 U/l [-24.4, 2.5]; p = 0.10). Absolute changes in PFC (-1.4% [-3.2, 0.3]; p = 0.106) and LSM (-1.31 kPa [-2.99, 0.37]; p = 0.123) were not significant when comparing the two groups. There were no serious drug-related adverse events. CONCLUSIONS/INTERPRETATION: When included in the standard treatment for type 2 diabetes, dulaglutide significantly reduces LFC and improves GGT levels in participants with NAFLD. There were non-significant reductions in PFC, liver stiffness, serum AST and serum ALT levels. Dulaglutide could be considered for the early treatment of NAFLD in patients with type 2 diabetes. TRIAL REGISTRATION: ClinicalTrials.gov NCT03590626 FUNDING: The current study was supported by an investigator-initiated study grant from Medanta-The Medicity's departmental research fund and a grant from the Endocrine and Diabetes Foundation (EDF), India.

RESUMO

BACKGROUND: The Indian railway system is the fourth largest in the world and causes about 15 deaths every day, due to intentional or unintentional reasons. This study presents a 5-year retrospective analysis of patients injured due to train-associated events, managed at a level-1 trauma center in India. MATERIALS AND METHODS: Hospital-based trauma registry data of train-associated injuries presenting between 2012 and 2016 were analyzed. Data from 726 patients were analyzed for demographics, injury events, injury regions, their management and outcomes. ISS and NISS were used to quantify the injury severity. RESULTS: Mean age was 33 years, with male-to-female ratio 86 to 14%. The majority of patients (62%) were between 20-40 years. The median ISS was 9 (IQR 4-16), median hospital stays 11 days (IQR6-23), with in-hospital mortality of 17.4%. Presence of head injury; ISS > 9 and CPR in ED were independent risk factors of mortality. Trespassers on the rail track had significantly more severe injuries compared to passengers (Median ISS 13 vs. 9, p = 0.012; Median NISS 22 vs.17, p = 0.015); however, mortality and hospital length of stay were not significantly different. Location of injury event (on platform or tracks) showed no difference between the severity of injuries, mortality and hospital length of stay. CONCLUSIONS: Current study reports comprehensive injury patterns and outcomes of train-associated injuries from a low- and middle-income country (LMIC). Apart from the mortality, there is a high incidence of permanent disabilities from extremity amputations. No significant difference was noted in the severity and outcomes among patients injured on or off train platforms, emphasizing the need for comprehensive safety measures including enforcement and promoting safe behavior not only on locations like train tracks but equally at platforms.

RESUMO

Although the well-accepted lower limit of the graft-to-recipient weight ratio (GRWR) for successful living donor liver transplantation (LDLT) remains 0.80%, many believe grafts with lower GRWR may suffice with portal inflow modulation (PIM), resulting in equally good recipient outcomes. This study was done to evaluate the outcomes of LDLT with small-for-size grafts (GRWR <0.80%). Of 1321 consecutive adult LDLTs from January 2012 to December 2017, 287 (21.7%) had GRWR <0.80%. PIM was performed (hemiportocaval shunt [HPCS], n = 109; splenic artery ligation [SAL], n = 14) in 42.9% patients. No PIM was done if portal pressure (PP) in the dissection phase was <16 mm Hg. Mean age of the cohort was 49.3 ± 9.1 years. Median Model for End-Stage Liver Disease score was 14, and the lowest GRWR was 0.54%. A total of 72 recipients had a GRWR <0.70%, of whom 58 underwent HPCS (1 of whom underwent HPCS + SAL) and 14 underwent no PIM, whereas 215 had GRWR between 0.70% and 0.79%, of whom 51 and 14 underwent HPCS and SAL, respectively. During the same period, 1034 had GRWR ≥0.80% and did not undergo PIM. Small-for-size syndrome developed in 2.8% patients. Three patients needed shunt closure at 1 and 4 weeks and 60 months. The 1-year patient survival rates were comparable. In conclusion, with PIM protocol that optimizes postperfusion PP, low-GRWR grafts can be used for appropriately selected LDLT recipients with acceptable outcomes.

RESUMO

Acute-on-chronic liver failure (ACLF) is a syndrome characterized by acute decompensation of previously diagnosed or undiagnosed liver disease with organ failure(s) with high short-term mortality. This study was conducted to report the outcomes of living donor liver transplantation (LDLT) in ACLF and assess the survival benefit of liver transplantation (LT) in these patients. It was a retrospective study of 218 ACLF patients on the basis of European Association for the Study of the Liver (EASL)-chronic liver failure criteria from January 2014 through November 2017. Patients were considered for LDLT if there was no improvement on standard medical therapy for 5-10 days. Prior to LDLT, active sepsis was excluded/treated, and renal, circulatory, and respiratory failures were improved to the greatest extent possible. The mean age was 42.9 years, and 181 patients were male. Sepsis was the most common acute precipitating event followed by alcohol. Of the patients, 35 (16.1%), 66 (30.3%), and 117 (53.7%) were classified into ACLF grades 1, 2, and 3, respectively. Although 80% of the ACLF 1 group and 72.7% of the ACLF 2 group underwent LDLT, only 35% of the ACLF 3 group could undergo LDLT. The circulatory and respiratory failures at admission were significantly higher in the nontransplant group with poor subsequent response to standard medical therapy, exclusion from LDLT, and poor outcomes. None of the patients on high support for circulatory and respiratory failure underwent LDLT. Posttransplant survival at 1 year was comparable among different grades of ACLF (92.9%, 85.4%, and 75.6%; P = 0.15). Among patients in the ACLF 3 group, survival at 90 days was extremely poor in those who could not undergo LDLT (5.9% versus 78%; P < 0.001). In conclusion, LDLT results in good survival with acceptable post-LT morbidity in patients with ACLF.

RESUMO

BACKGROUND AND AIMS: Chronic rejection (CR) is an uncommon but important cause of graft dysfunction, leading to graft loss and often requires retransplantation. This study evaluates the incidence and outcome of the patients with CR at a large living donor liver transplant (LDLT) center. METHODS: Data of patients with CR were retrospectively analyzed in 1232 adult (age >18 years) LDLT on tacrolimus (mainly)-based immunosuppression. Sirolimus/everolimus (mammalian target of rapamycin [mTOR] inhibitors) was added to baseline immunosuppression as rescue therapy in patients with CR. Data are shown as median (interquartile range [IQR]). RESULTS: Twenty-three patients (22 males), aged 42 (IQR 45-56) years, had biopsy-proven chronic rejection at 21 (8-44) months after liver transplantation. The incidence of chronic rejection was 1.9% in this cohort. The patients with CR (n = 23) had a significantly higher incidence of cytomegalovirus (CMV) viremia, acute cellular rejection, and history of anastomotic biliary strictures as compared to patients without CR. Five patients were noncompliant with immunosuppression before the diagnosis of CR. Twelve patients (52%) responded to addition of mTOR inhibitors, whereas 11 did not respond and had poor outcome. CONCLUSION: The incidence of chronic rejection is low in LDLT. Treatment with mTOR inhibitors can reverse graft dysfunction in approximately half of the patients.

RESUMO

BACKGROUND: Cytomegalovirus (CMV) is the most common viral infection in liver transplant recipients that influences the outcomes of liver transplantation. However, its impact on early outcomes following living donor liver transplantation (LDLT) is not fully defined in the Indian subcontinent. This study was done to assess the impact of CMV infection on early post-transplant outcomes in LDLT recipients. METHODS: Out of 272 LDLTs performed from January 2012 to April 2013, 151 recipients underwent CMV viral load analysis in plasma within 90 days post LDLT based on clinical suspicion. Patients with CMV infection (n = 55) were compared with those without CMV infection (n = 96). RESULTS: The median time interval of CMV infection from LDLT was 25 days (range 2-90 days). The mean age of study population was 48.92 years. About 116 (76.8%) of the patients were male. Hepatitis C virus (HCV) (39.1%)-related chronic liver disease (CLD) was most common indication for liver transplant. No statistically significant difference was observed in etiology of liver disease (P = .38), Chid-Turcotte-Pugh (CTP) (P = .41), and Model for End-stage Liver Disease (MELD) (P = .12) scores between the groups. Patients with CMV infection had significantly higher incidence of acute cellular rejection (16.1% vs 5.4%, P = .02); longer ICU stay (P = .01); and a higher overall 90-day mortality (24.2% vs 6.7%, P = .001). Bacteremia and fungemia were significantly more common in the CMV infection group. CONCLUSION: Cytomegalovirus infection significantly influences the early post LDLT outcomes and contributes to increased overall mortality.

RESUMO

In countries where deceased organ donation is scarce, there is a big gap between demand and supply of organs and living donor liver transplantation (LDLT) plays an important role in meeting this unmet need. This study was conducted to analyze the effect of pretransplant Model for End-stage Liver Disease (MELD) score on outcomes following LDLT. The outcome of 1000 patients who underwent LDLT from July 2010 to March 2015 was analyzed retrospectively. Patients were grouped into low MELD<25 and high MELD ≥25 score to compare short-term outcomes. Cumulative overall survival rates were calculated using Kaplan-Meier methods. A total of 849 recipients were in low MELD group (Mean MELD=16.90±9.2) and 151 were in high MELD group (Mean MELD=28.77±7.2). No significant difference in etiology of CLD was observed between groups except for a higher prevalence of hepatitis C virus (29.6% vs 19.9%, P=.01) in low MELD patients. No significant difference was observed in 1-year survival (88.5% vs 84.1%, P=.12) between the groups. The multivariate analysis showed that pretransplant MELD score does not predict survival of recipients. Pretransplant high MELD score does not adversely affect outcomes after LDLT. In view of shortage of deceased organs, LDLT can be a good option in high MELD recipients.

RESUMO

INTRODUCTION: Drug-induced acute liver failure (ALF) is associated with high mortality. There is limited literature on results of living donor liver transplantation (LDLT). MATERIAL AND METHODS: The study was conducted at a tertiary care center in North India. All patients who received LDLT for drug-induced ALF were included. The data are shown as median (IQR). RESULTS: A total of 18 patients (15 females and three males), aged 34 (25-45) years, underwent LDLT for drug-induced liver injury (DILI)-related ALF. Etiology of ALF was antitubercular medications (n=14), orlistat (n=1), flutamide (n=1), and complementary alternative medications (n=2). The baseline parameters were as following: bilirubin 17.7 (16.3-23.8) mg/dL, INR 3.3 (2.5-4.0), jaundice encephalopathy interval 6 (3-17.5) days, arterial ammonia 109 µmol/L (73-215), Model for End-Stage Liver Disease (MELD) 24 (18-33), grade of encephalopathy 2 (1-4), which progressed to grade 3 (3-4) before transplantation. All patients underwent right lobe LDLT; hospital stay was 17 (13-22) days, and ICU stay was 5 (5-7) days. Two patients died in the first month after liver transplantation due to sepsis and multi-organ failure; the rest of the patients are alive and doing well at a follow-up of 50 (4-82 months). CONCLUSION: Good outcomes can be obtained by LDLT for drug-induced ALF.

RESUMO

BACKGROUND: Metabolic risk factors should be important in addition to imaging for prediction of steatosis in prospective liver donors. MATERIALS AND METHODS: The study group included all prospective liver donors who had a liver biopsy during workup. Risk factors of metabolic syndrome were analyzed, and body mass index (BMI) ≥25 kg/m2 was used in place of waist circumference. Three BMI cutoffs (25, 28, and 30 kg/m2 ) and two CT-measured liver attenuation index (LAI) cutoffs (<5 and ≤10) were used for steatosis assessment of ≥5%, ≥10%, and ≥20%. RESULTS: Of the 573 prospective donors (307 females), 282 (49.2%) donors had nonalcoholic fatty liver (NAFL). When donors with NAFL were compared with donors having normal histology, multivariate analysis showed BMI, ALT, triglycerides, and LAI as significant predictors of NAFL. BMI ≥25 kg/m2 and LAI <10 were better cutoffs. The presence of ≥2 metabolic risk factors had better sensitivity than CT-LAI for the presence of NAFL and ≥20% steatosis (58% and 54% vs 47% and 22%, respectively, for CT-LAI ≤10). The presence of LAI >10 and <2 metabolic risk factors predicted <10% steatosis with 96% specificity and 92% positive predictive value. CONCLUSION: The presence of ≥2 metabolic risk factors improves sensitivity of CT-LAI for prediction of donor steatosis.

RESUMO

We modified the previously described D-MELD score in deceased donor liver transplant, to (D+10)MELD to account for living donors being about 10 years younger than deceased donors, and tested it on living donor liver transplantation (LDLT) recipients. Five hundred consecutive LDLT, between July 2010 and December 2012, were retrospectively analyzed to see the effect of (D+10)MELD on patient and graft survival. Donor age alone did not influence survival. Recipients were divided into six classes based on the (D+10)MELD score: Class 1 (0-399), Class 2 (400-799), Class 3 (800-1199), Class 4 (1200-1599), Class 5 (1600-1999), and Class 6 (>2000). The 1 year patient survival (97.1, 88.8, 87.6, 76.9, and 75% across Class 1-5, P=.03) and graft survival (97.1, 87.9, 82.3, 76.9, and 75%; P=.04) was significantly different among the classes. The study population was divided into two groups at (D+10)MELD cut off at 860. Group 1 had a significantly better 1 year patient (90.4% vs 83.4%; P=.02) and graft survival (88.6% vs 80.2%; P=.01). While donor age alone does not predict recipient outcome, (D+10)MELD score is a strong predictor of recipient and graft survival, and may help in better recipient/donor selection and matching in LDLT.
