Background Although laparoscopic sleeve gastrectomy is known, in general, to improve renal function in patients with obesity and chronic kidney disease (CKD), its effect on estimated glomerular filtration rate (eGFR) stratified by the stage of CKD is less clear. Objectives We aimed to evaluate the impact of sleeve gastrectomy on renal function in a stratified cohort of patients with CKD. Setting University Hospital. Methods We performed a retrospective review of 1932 patients who met National Institutes of Health’s guidelines for metabolic surgery and underwent laparoscopic sleeve gastrectomy performed by 1 of 3 surgeons. One hundred sixty-four patients with CKD stages 1 through 4 were identified. Results Mean follow-up period was 1.57 ± 1.0 years. Mean age was 56.4 ± 9.9 years with a preoperative body mass index of 47 ± 9 kg/m2, which decreased to 38.9 ± 8.7 kg/m2 at most recent follow-up (P Conclusion Renal function, as measured by eGFR, in patients with stages 1 and 4 CKD did not improve after laparoscopic sleeve gastrectomy; in contrast, eGFR in patients with CKD stages 2 and 3 significantly improved. Early surgical referral and intervention may be important in achieving the greatest improvement in eGFR and possibly delaying or reversing progression to end-stage renal disease.

Because of underutilization of liver allografts, our center previously showed that hepatitis C virus (HCV) antibody-positive/nucleic acid test (NAT)-negative livers when transplanted into HCV nonviremic recipients were safe with a 10% risk of HCV transmission. Herein, we present our single-center prospective experience of using HCV NAT+ liver allografts transplanted into HCV NAT- recipients. An institutional review board-approved matched cohort study was conducted examining post- liver transplantation (LT) outcomes of HCV- patients who received HCV NAT+ organs (treatment group) compared with matched recipients with HCV NAT- organs (matched comparator group) between June 2018 to October 2019. The primary endpoint was success of HCV treatment and elimination of HCV infection. The secondary outcomes included the 30-day and 1-year graft and patient survival as well as perioperative complications. There were 32 recipients enrolled into each group. Because of 1 death in the index admission, 30/31 patients (97%) were given HCV treatment at a median starting time of 47 days (18-140 days) after LT. A total of 19 (63%) patients achieved sustained virological response at week 12 (SVR12). Another 6 patients achieved end-of-treatment response, while 5 remained on therapy and 1 is yet to start treatment. No HCV treatment failure has been noted. There were no differences in 30-day and 1-year graft and patient survival, length of hospital stay, biliary or vascular complications, or cytomegalovirus viremia between the 2 groups. In this interim analysis of a matched cohort study, which is the first and largest study to date, the patients who received the HCV NAT+ organs had similar outcomes regarding graft function, patient survival, and post-LT complications.

Obesity is increasing to unprecedented levels, including in the end-stage kidney disease population, where upwards of 60% of kidney transplant patients are overweight or obese. Obesity poses additional challenges to the care of the dialysis patient, including difficulties in creating vascular access and inserting Tenckhoff catheters, higher rates of catheter malfunction and peritonitis, the need for longer and/or more frequent dialysis (or peritoneal dialysis [PD] exchanges) to achieve adequate clearance, increased metabolic complications particularly with PD, and obesity is a barrier to kidney transplantation. In this article, we review special considerations in performing PD, hemodialysis and transplant in the obese patient, as well as the evidence behind medical and surgical management of obesity in dialysis patients.

Simultaneous liver-kidney transplantation (SLKT) is indicated for patients with end-stage liver disease (ESLD) and concurrent renal insufficiency. En bloc SLKT is an alternative to traditional separate implantations, but studies comparing the two techniques are limited. The en bloc technique maintains renal outflow via donor infrahepatic vena cava and inflow via anastomosis of donor renal artery to donor splenic artery. Comparison of recipients of en bloc (n = 17) vs traditional (n = 17) SLKT between 2013 and 2017 was performed. Recipient demographics and comorbidities were similar. More recipients of traditional SLKT were dialysis dependent (82.4% vs 41.2%, P = .01) with lower baseline pretransplant eGFR (14 vs 18, P = .01). En bloc SLKT was associated with shorter kidney cold ischemia time (341 vs 533 minutes, P < .01) and operative time (374 vs 511 minutes, P < .01). Two en bloc patients underwent reoperation for kidney allograft inflow issues due to kinking and renal steal. Early kidney allograft dysfunction (23.5% in both groups), 1-year kidney graft survival (88.2% vs 82.4%, P = 1.0), and posttransplantation eGFR were similar between groups. In our experience, the en bloc SLKT technique is safe and feasible, with comparable outcomes to the traditional method.

Morbid obesity is a barrier to kidney transplant in patients with end-stage renal disease (ESRD). Laparoscopic sleeve gastrectomy (SG) is an increasingly considered intervention, but the safety and long-term outcomes are uncertain. We reviewed prospectively collected data on patients with ESRD and chronic kidney disease (CKD) undergoing SG from 2011 to 2018. There were 198 patients with ESRD and 45 patients with CKD (stages 1-4) who met National Institutes of Health guidelines for bariatric surgery and underwent SG; 72% and 48% achieved a body mass index of ≤ 40 and ≤ 35 kg/m2 , respectively. The mean percentages of total weight loss and excess weight loss were 18.9 ± 10.8% and 38.2 ± 20.3%, respectively. SG reduced hypertension (85.8% vs 52.1%), decreased antihypertensive medication use (1.6 vs 1.0) (P < .01 each), and reduced incidence of diabetes (59.6% vs 32.5%, P < .01). Of the 71 patients with ESRD who achieved a body mass index of ≤ 40 kg/m2 , 45 were waitlisted and received a kidney transplant, whereas 10 remain on the waitlist. Mortality rate after SG was 1.8 per 100 patient-years, compared with 7.3 for non-SG. Patients with stage 3a or 3b CKD exhibited improved glomerular filtration rate (43.5 vs 58.4 mL/min, P = .01). In conclusion, SG safely improves transplant candidacy while providing significant, sustainable effects on weight loss, reducing medical comorbidities, and possibly improving renal function in stage 3 patients.

Morbid obesity serves as a barrier to kidney transplantation (KT) due to potential suboptimal posttransplant outcomes. Laparoscopic sleeve gastrectomy (LSG) has previously been shown to improve transplant eligibility through weight loss.We aimed to examine the role LSG plays in improving patient outcomes postrenal transplantation, including possible impact on new-onset diabetes after transplant (NODAT).University Hospital.A single-center analysis was performed identifying all patients who underwent KT after LSG from 2011 to 2017 (n = 41). Exclusion criteria included type I diabetes and previous pancreas transplantation. NODAT was defined as a new insulin requirement after KT. Delayed graft function was defined as need for dialysis within the first week after KT. Mean posttransplant follow-up period was 22 months.Forty-one patients underwent KT after LSG after median time of 16 months. Median age of postLSG patients undergoing KT was 56.0 years at time of KT. Average body mass index decreased by 9 from the time of LSG to KT, and no patients regained weight at 1-year follow-up. After LSG, the number of patients with hypertension (85.4% versus 48.5%) and the number of antihypertensive medications used decreased significantly (1.6 versus .6) at time of KT (P.001 each). At 1-year follow-up, the improvement in hypertension persisted (51.2% versus 48.5%, P = nonsignificant). The average insulin regimen decreased from 33.0 ± 51.6 to 11.7 ± 21.5 units at KT (P.001). This improvement also persisted at 1-year follow-up (11.9 versus 11.7 units, P = nonsignificant). Zero patients suffered NODAT over the follow-up period (versus institutional rate of NODAT at 15.8%). One patient developed delayed graft function (2.4%, versus institutional rate of 13.3%). After 1 year postKT, there was 1 graft loss (2.4%) and no mortality.This is the largest reported series of KT after planned LSG in morbidly obese patients. Our results confirm excellent posttransplant outcomes among patients who otherwise would have been denied KT eligibility.

Traditional piggyback implantation has often been used in liver transplant; however, this technique may be hindered by difficult visualization and postoperative incidences of outflow obstruction. Side-to-side cavocavostomy is an alternative approach, but perioperative outcomes associated with this technique remain largely unknown.In July 2017, side-to-side cavocavostomy was adopted as the standard implantation technique at our institution by all surgeons (n = 4). A prospective cohort of patients undergoing liver transplant with side-to-side cavocavostomy after July 2017 until October 2018 was compared with a historical cohort of patients who underwent liver transplant with traditional piggyback previously from January 2016 to October 2018.Of 290 liver transplant patients, 50% (n = 145) underwent side-to-side cavocavostomy, while the remainder underwent traditional piggyback. There were no differences in recipient age, sex, race, Model for End-Stage Liver Disease score, or donor characteristics between groups. Side-to-side cavocavostomy was associated with decreased mean number intraoperative, red blood cell transfusions (2 vs 5 units), fresh frozen plasma (5 vs 10 units), cell saver (1.0 vs 2.0 L), and rates of temporary abdominal closure (8.3% vs 24.1%) compared with traditional piggyback (all P.05). The side-to-side cavocavostomy group had lesser Rt3s of postoperative transfusion rates of red blood cells (21.4% vs 35.9%; P = .01).Side-to-side cavocavostomy may be superior to traditional piggyback implantation with regard to technical ease and perioperative transfusion requirements. To determine the optimal implantation technique, futures studies should evaluate side-to-side cavocavostomy versus traditional piggyback in a prospective, multicenter, randomized approach.

Although increased hospital volume has been correlated with improved outcomes in certain surgical procedures, the effect of center volume on pancreas transplantation (PT) is less understood. Our study aims to establish whether a volume-outcome effect exists for PT.Through an established linkage between the University HealthSystem Consortium and the Scientific Registry of Transplant Recipients (SRTR) databases, we performed a retrospective cohort analysis of adult PT recipients between 2009 and 2012. Surgical volume was divided equally into low volume (LV), middle volume (MV), and high volume (HV) tertiles for each year that was studied. Hospital outcomes were measured through University HealthSystem Consortium, and long-term outcomes were measured through Scientific Registry of Transplant Recipients. Statistical analysis was performed using regression analyses and the Kaplan-Meier method. Median follow-up period was 2 y.Among the 2309 PT recipients included, 815 (35.3%) were performed at LV centers, 755 (32.7%) at MV centers, and 739 (32.0%) at HV centers. Compared with MV and LV centers, organs transplanted at HV centers were more frequently donation after cardiac death (5.1% versus 2.4% versus 3.3%, P = 0.01) and from older donors (2.8% [50 y] versus 0.8% versus 0.1%, P 0.001). In addition, HV recipients were older (31.5% [50 y] versus 20.9% versus 19.7%, P 0.001) and had worse functional status (39.5% dependent versus 9.7% versus 9.9%, P 0.001). Patient and graft survival were similar across hospital volume tertiles. Center volume was not predictive of readmission rates, total length of stay, intensive care unit length of stay, or total direct cost on multivariate analysis (all P 0.05).Short- and long-term outcomes after PT are not affected by hospital volume. Although LV centers confine their cases to low-risk patients, HV centers transplant a higher percentage of high-risk donor and recipient combinations with equivalent outcomes.

Obesity has become an epidemic in the United States over the past decade, and recent studies have shown this trend in the liver transplantation (LT) population. These patients may be candidates for laparoscopic sleeve gastrectomy (LSG) to promote significant and sustained weight loss to prevent recurrence of nonalcoholic steatohepatitis. However, safety remains a concern, and efficacy in this setting is uncertain. A single-institution database from 2014 to 2018 was queried for patients undergoing LSG following LT. The selection criteria for surgery were consistent with National Institutes of Health guidelines, and patients were at least 6 months after LT. A total of 15 patients (median age, 59.0 years; Caucasian, 86.7%; and female, 60%) underwent LSG following LT. Median time from LT to LSG was 2.2 years with a median follow-up period of 2.6 years. The median hospital length of stay (LOS) was 2 days after LSG. Mortality and rate of liver allograft rejection was 0, and there was 1 postoperative complication (a surgical site infection). Following LSG, body mass index (BMI) decreased from 42.7 to 35.9 kg/m2 (P < 0.01), and in 12 patients with at least 1 year of follow-up, the total body weight loss was 20.6%. Following LSG in patients with diabetes, the median daily insulin requirements decreased from 98 (49-118) to 0 (0-29) units/day (P = 0.02), and 60% discontinued insulin. Post-LT patients had a similar decrease in BMI and reduction in comorbidities at 1 year compared with a matched non-LT patient cohort. In the largest patient series to date, we show that LSG following LT is safe, effective, and does not increase the incidence of liver allograft rejection. Larger longer-term studies are needed to confirm underlying metabolic changes following LSG.

Most transplant centers decline morbidly obese people for living kidney donation. Their inclusion in the living donor pool after weight loss and reversal of comorbidities by bariatric surgery could reverse the downward living donation trend. We investigated whether bariatric surgery in the morbidly obese altered their candidacy for donation, complicated their subsequent donor nephrectomy, and impacted their early postoperative outcomes in a series of 22 donors who had bariatric surgery 0.7-22 years prior to laparoscopic living donor nephrectomy. Eighteen would have been excluded from donation prior to bariatric surgery based on a body mass index (BMI) > 40. Seventeen reached a BMI < 35 after bariatric surgery. One had hypertension that resolved after bariatric surgery. Prior bariatric surgery did not influence port placement and laterality of donor nephrectomy. None required open conversion or blood transfusion. In an exploratory comparison with 37 donors with a BMI 35-40, length of stay and warm ischemic time were shorter, blood loss and postoperative complications were similar, and operative time was longer. We therefore advocate the consideration of bariatric surgery in preparation for donation in morbidly obese people since it positively alters their candidacy without major impact on the subsequent living donor nephrectomy and early outcomes.

Hepatitis C (HCV) disease transmission from the use of HCV antibody-positive and HCV nucleic acid test-negative (HCV Ab+/NAT-) kidneys have been anecdotally reported to be absent. We prospectively analyzed kidney transplant (KT) outcomes from HCV Ab+/NAT- donors to HCV naive recipients under T-cell depleting early steroid withdrawal immunosuppression. Allografts from 40 HCV Ab+/NAT- donors were transplanted to 52 HCV Ab- recipients between July 2016 and February 2018. Thirty-three (82.5%) of donors met Public Health Service (PHS) increased risk criteria. De novo HCV infection was detected at 3 months post-KT in one recipient (1.9%). This was a case of transmission from a HCV Ab+ NAT+ donor with an initial false-negative NAT completed using sample collected on donor hospital admission (day 2). At the time of HCV diagnosis, a stored donor sample collected during procurement (day 4) was tested and resulted NAT-positive. Subsequently, sustained virologic response (SVR) was achieved with 12 weeks of glecaprevir/pibrentasvir. One death with functioning graft at 261 days post-KT was determined not related to HCV or donor factors. This experience provides evidence of a low transmission rate of HCV from HCV Ab+/ NAT- kidney donors, thereby arguing for increasing utilization.

The use of donation after circulatory death (DCD) liver allografts has been constrained by limitations in the duration of donor warm ischemia time (DWIT), donor agonal time (DAT), and cold ischemia time (CIT). The purpose of this study is to assess the impact of longer DWIT, DAT, and CIT on graft survival and other outcomes in DCD liver transplants. The Scientific Registry of Transplant Recipients was queried for adult liver transplants from DCD donors between 2009 and 2015. Donor, recipient, and center variables were included in the analysis. During the study period, 2107 patients underwent liver transplant with DCD allografts. In most patients, DWIT and DAT were30 minutes. DWIT was30 minutes in 1804 donors, between 30 and 40 minutes in 248, and40 minutes in 37. There was no difference in graft survival, duration of posttransplant hospital length of stay, and readmission rate between DCD liver transplants from donors with DWIT30 minutes and DWIT between 30 and 40 minutes. Similar outcomes were noted for DAT. In the multivariate analysis, DAT and DWIT were not associated with graft loss. The predictors associated with graft loss were donor age, donor sharing, CIT, recipient admission to the intensive care unit, recipient ventilator dependence, Model for End-Stage Liver Disease score, and low-volume transplant centers. Any CIT cutoff4 hours was associated with increased risk for graft loss. Longer CIT was also associated with a longer posttransplant hospital stay, higher rate of primary nonfunction, and hyperbilirubinemia. In conclusion, slightly longer DAT and DWIT (up to 40 minutes) were not associated with graft loss, longer posttransplant hospitalization, or hospital readmissions, whereas longer CIT was associated with worse outcomes after DCD liver transplants.

Background Given the shortage of available liver grafts, transplantation (LTx) of hepatitis C virus antibody-positive, nucleic acid test-negative (HCV Ab+/NAT-) livers into nonviremic HCV recipients can expand the donor pool. Having previously described the sentinel experience of HCV Ab+/NAT- allografts in nonviremic recipients, we report the growth and extended follow-up of this program for 55 patients compared with recipients of Public Health Services (PHS) increased-risk donor HCV Ab-/NAT- allografts. Study Design A prospective review of all HCV nonviremic LTx patients receiving HCV Ab+/NAT- organs between March 2016 and August 2018 was performed. All HCV Ab+/NAT- organ recipients underwent HCV testing at 3 months and 1-year post-LTx to determine HCV transmission. Results Fifty-five HCV nonviremic candidates received HCV Ab+/NAT- organs; 64% male, median age 59 years (range 36 to 69 years) and median Model for End-Stage Liver Disease score of 22.5. Two recipients were excluded due to death before HCV testing. The HCV disease transmission occurred in 5 recipients (9%). Of these, 4 (80%) underwent anti-HCV treatment with eradication of virus. No patient found to be negative at 3 months seroconverted at 1-year follow-up. No patients who received PHS increased-risk donor HCV Ab-/NAT- organs had viremia develop (0 of 57) and there was no difference in graft and renal function, complications, or survival between HCV Ab+/NAT- recipients and PHS increased-risk donor HCV Ab-/NAT- recipients. Conclusions We report the largest experience with LTx from HCV Ab+/NAT- donors into 55 seronegative recipients with a HCV transmission rate of 9% with no late conversions at 1 year and no difference in function or graft loss compared with PHS increased-risk donor HCV Ab-/NAT- recipients. Due to availability of safe and effective HCV therapies, the use of such organs should be strongly considered to increase the donor organ pool.

INTRODUCTION The use of liver allografts from elderly donors (≥70 years) has increased because of organ shortage and increased life expectancy. The aim of this study is to evaluate the current utilization of elderly donors in United States, recipient selection, and their posttransplant outcomes. METHODS A linkage between Scientific Registry of Transplant Recipients and University HealthSystem Consortium databases was performed. Between January 2007 and December 2011, 12,445 liver transplant (LT) recipients were identified and divided into 2 cohorts based on donor age: 70 years or older (n = 540) and younger than 60 years (n = 10,473). RESULTS Elderly donors accounted for 4.3% of all donors used in the 5-year period. When compared to younger donors, elderly donors were more likely to be women, shared regionally or nationally, and used at higher volume centers. Elderly donor allografts were less likely to be used in recipients with model of end-stage liver disease score higher than 27 (13.2% vs. 23.0%, P < 0.001), hospitalized (16.8% vs. 21.7%, P = 0.03), or on hemodialysis at time of transplant (2.6% vs. 8.2%, P < 0.001). Both recipient groups had similar perioperative mortality, 30-day readmission rates, and short-term patient survival. In the multivariate analysis, including recipient, donor, center and regional factors, donor age 70 years or older was associated with slightly increased risk of graft loss (hazard ratio, 1.3; 95% confidence interval, 1.08-1.56; P = 0.005). CONCLUSIONS The current trend toward the use of elderly donors in liver transplant recipients with low model of end-stage liver disease scores (

We aimed to characterize variability in cost after straightforward orthotopic liver transplant (OLT).Using the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases, we identified patients who underwent OLT between 2011 and 2014. Patients meeting criteria for straightforward OLT, defined as length of stay 14 days with discharge to home, were selected (n = 5763) and grouped into tertiles (low, medium, high) according to cost of perioperative stay.Patients undergoing straightforward OLT were of similar demographics regardless of cost. High cost patients were more likely to require preoperative hemodialysis, had higher severity of illness, and higher model for end-stage liver disease (MELD) (p 0.01). High cost patients required greater utilization of resources including lab tests, blood transfusions, and opioids (p 0.01). Despite having higher burden of disease and requiring increased resource utilization, high cost OLT patients with a straightforward perioperative course were shown to have identical 2-year graft and overall survival compared to lower cost patients (p = 0.82 and p = 0.63), respectively.Providing adequate perioperative care for OLT patients with higher severity of illness and disease burden requires increased cost and resource utilization; however, doing so provides these patients with long term survival equivalent to more routine patients.

While previous studies have demonstrated short-term efficacy of laparoscopic sleeve gastrectomy in candidates awaiting renal transplantation, the combination of morbid obesity and end-stage renal disease presents unique challenges to perioperative care. We demonstrate how increasing experience and the development of postoperative care guidelines can improve outcomes in this high-risk population.Single-center medical records were reviewed for renal transplantation candidates undergoing laparoscopic sleeve gastrectomy between 2011 and 2015 by a single surgeon. Postoperative care protocols were established and continually refined throughout the study period, including a multidisciplinary approach to inpatient management and hospital discharge planning. The first 100 laparoscopic sleeve gastrectomy patients were included and divided into 4 equal cohorts based on case sequence.Compared with the first 25 patients undergoing laparoscopic sleeve gastrectomy, the last 25 patients had shorter operative times (97.8 ± 27.9 min vs 124.2 ± 33.6 min), lower estimated blood loss (6.6 ± 20.8 mL vs 34.0 ± 38.1 mL), and shorter hospital duration of stay (1.7 ± 2.1 days vs 2.9 ± 0.7 days) (P .01 each). Readmission rates, complications, and 1-year mortality did not differ significantly.Increasing experience and the development of clinical care guidelines in this high-risk population is associated with reduced health care resource utilization and improved perioperative outcomes.

Background Metabolic syndrome is increasing among patients undergoing liver transplantation. Nonalcoholic steatohepatitis is a manifestation of metabolic syndrome and is an increasingly common cause of end-stage liver disease necessitating orthotopic liver transplantation. We sought to determine the effect of preoperative risk factors on the development of post-transplant metabolic syndrome, complications, readmissions, and mortality. Methods We conducted a review of 114 orthotopic liver transplantations at our institution from May 2012 to April 2014. Results Patients with (n = 19) and without (n = 95) metabolic syndrome were similar with regard to age, race, and model for end-stage liver disease at time of transplant. Donor and operative factors also were similar between the groups. Preoperative diabetes was found to be associated with an increased rate of readmission (odds ratio 3.45, P = .03). While preoperative metabolic syndrome itself was not a significant predictor of worse outcomes, postoperative metabolic syndrome was associated with significantly greater readmissions in the first year. Major predictors of new onset metabolic syndrome after orthotopic liver transplantation included preoperative diabetes and obesity (odds ratio 8.54 and odds ratio 5.49, P Conclusion Efforts to decrease the incidence of postoperative metabolic syndrome after orthotopic liver transplantation may decrease readmissions and improve outcomes, along with decreasing resource utilization.

Sensitized renal transplant recipients with high levels of donor-specific alloantibody (DSA) commonly develop antibody-mediated rejection (AMR), which may cause acute graft loss or shorten allograft survival. We examined the efficacy of terminal complement inhibition with the humanized anti-C5 antibody, eculizumab, in the prevention AMR in renal transplant recipients with a positive crossmatch against their living donor. The incidence of biopsy-proven AMR in the first 3 months posttransplant in 26 highly sensitized recipients of living donor renal transplants who received eculizumab posttransplant was compared to a historical control group of 51 sensitized patients treated with a similar plasma exchange (PE)-based protocol without eculizumab. The incidence of AMR was 7.7% (2/26) in the eculizumab group compared to 41.2% (21/51) in the control group (p = 0.0031). Eculizumab also decreased AMR in patients who developed high levels of DSA early after transplantation that caused proximal complement activation. With eculizumab, AMR episodes were easily treated with PE reducing the need for splenectomy. On 1-year protocol biopsy, transplant glomerulopathy was found to be present in 6.7% (1/15) eculizumab-treated recipients and in 35.7% (15/42) of control patients (p = 0.044). Inhibition of terminal complement activation with eculizumab decreases the incidence of early AMR in sensitized renal transplant recipients (ClincalTrials.gov number NCT006707).

Summary The aim of this study was to analyze the impact of morbid obesity in recipients on peritransplant resource utilization and survival outcomes. Using a linkage between the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases, we identified 12 445 patients who underwent liver transplantation (LT) between 2007 and 2011 and divided them into two cohorts based on recipient body mass index (BMI

BG is a 27-year-old man originally diagnosed with portal, splenic, and superior mesenteric vein thrombosis in 2007 during a work-up for abdominal pain. A subsequent hypercoagulable work-up was negative. He was placed on oral anticoagulation as an outpatient but failed due to repeated noncompliance. He represented in 2012 with massive upper gastrointestinal hemorrhage from his esophagogastric varices, requiring placement of a Minnesota tube to facilitate bleeding cessation. The patient underwent a protracted surgical intensive care unit course with numerous packed red blood cell transfusions. He eventually stabilized with sclerotherapy consisting of intravariceal cyanoacrylate injection, but he remained inhouse for continued monitoring and occasional ongoing transfusions. Following hemodynamic stabilization, repeat imaging demonstrated diffuse, completely occluding thrombosis throughout his portal, splenic, and superior mesenteric veins (Fig. 1a). He was therefore not a candidate for transjugular intrahepatic portosystemic shunt (TIPS) due to lack of venous flow. Given his lack of traditional shunting options, he was consented to undergo splenopneumopexy. His postoperative course was uneventful, and he was discharged 10 days following the procedure. Follow-up imaging performed 3 months postoperatively demonstrated the development of collateral portopulmonary circulation and decompression of his esophagogastric varices (Fig. 1b). With a current follow-up of 18 months, the patient has had no evidence of repeated gastrointestinal hemorrhage.

In Ohio, the obesity rate has increased from 21.5% in 2000 to 30.1% in 2012. Nonalcoholic steatohepatitis is believed to be increasing as an indication for orthotopic liver transplantation.We evaluated the diagnosis of nonalcoholic steatohepatitis as an indication for orthotopic liver transplantation and ensuing outcomes relative to other common hepatic diseases requiring orthotopic liver transplantation in Ohio. We queried 2,356 patients with nonalcoholic steatohepatitis, alcoholic cirrhosis (ETOH), and hepatitis C cirrhosis from the Ohio Solid Organ Transplantation Consortium who were listed for and/or received an orthotopic liver transplant from 2000 to 2012.The proportion of listed patients with nonalcoholic steatohepatitis increased from 0% to 26% and the proportion of transplanted patients increased from 0% to 23.4%. Compared with patients with hepatitis C and ETOH, patients with nonalcoholic steatohepatitis were older, and more likely to be white, and have private insurance (P .05 for each). There was no difference in median waiting time among patients with nonalcoholic steatohepatitis, hepatitis C, and ETOH (P = .18) and Model for End-Stage Liver Disease scores at orthotopic liver transplantation among patients with nonalcoholic steatohepatitis, hepatitis C (P = .48), and ETOH (P = .27). Patient and graft survival after orthotopic liver transplantation was comparable between patients with nonalcoholic steatohepatitis and ETOH (P = .79 and P = .86, respectively); however, patients with nonalcoholic steatohepatitis had better patient and graft survival compared with patients with hepatitis C after orthotopic liver transplantation (P .01 and P = .02, respectively). Additionally, body mass index had no influence on overall or graft survival for patients with nonalcoholic steatohepatitis undergoing orthotopic liver transplantation.This study reflects the growing potential for transplantation in patients with fatty liver disease and suggests the outcomes are equivalent or superior to other common indications for orthotopic liver transplantation.

Background: Preventable readmissions have become a focal point for controlling cost and improving quality in medicine. The frequency and causes of readmissions after liver transplantation (OLT) at 30 days and 1 year have not been described. We aimed to determine the risk factors, rate, and outcomes of readmissions within the first year after OLT and its potential impact on patient and graft survival. Methods: Medical records of 239 consecutive patients who underwent OLT from 2007 to 2012 at University of Cincinnati Medical Center were reviewed. Fifteen patients were excluded owing to death (n = 11) or retransplantation (n = 4) within the same hospital stay. Transplant- and non-transplant-related factors were collected during the index admissions and potential readmissions. This database was then linked to the Scientific Registry of Transplant Recipients to link donor- and recipient-related data. Results: One hundred fifty-four patients (69%) were readmitted within 1 year after OLT, for a total of 413 readmissions (average, 2.7 readmissions per patient) and a median hospital length of stay of 4 days. There were 118 readmissions within the first 30 days in 41% of patients (92/224). Sixty-five percent of patients readmitted within 30 days after discharge (69/92) were hospitalized again at least once within the year. Twenty-nine percent of patients (64/224) were discharged to a rehabilitation center after OLT; if discharged to a rehabilitation center, these patients had a 53% and 81% risk of readmission in 30 days and 1 year, respectively, compared with patients discharged home (36% and 64%, respectively; P = .02). The most common reasons for readmission within the first 30 days after discharge were infection (19.5%), renal insufficiency (9.3%), vomiting/diarrhea (8.5%), and pulmonary edema/effusion (7.6%). The most common reasons for readmission after 1 month were infection (24.8%), acute cellular rejection (8.5%), and biliary complications (7.1%).

NOTES has become a clinical reality. There remain, however, many challenges that need to be addressed in order to refine the technique. One of the most feared potential complications of transgastric surgery is a leak from the port of entry into the peritoneum. When withdrawing the endoscope into the gastric lumen it is difficult to make a secure closure due to the loss of pneumogastrium. We present a novel and safe technique for creating a gastrotomy developed in our animal laboratory and applied in all of our human NOTES cholecystectomies.Using an aggressive grasping and needle-delivery device, full-thickness bites create an imbricated ridge of tissue that acts as a valve, allowing visualization while maintaining pneumogastrium when the endoscope is withdrawn from the peritoneum into the lumen. At closure, full-thickness serosa-to-serosa approximation is easily achieved due to excellent visualization.With this technique we have been able to accomplish consistent results in ten pig models. In our series of five patients who have undergone NOTES transgastric cholecystectomy, there have been no leaks to date using the same technique. Video footage presents this technique performed on humans.Creation of a gastric valve during transgastric surgery has proved to be a safe approach. This technique allows maintenance of insufflation and visualization during the procedure and provides a feasible and safe means of closure at the end of the procedure.
