Abstract
BACKGROUND SPLIT was founded in 1995 in order to collect comprehensive prospective data on pediatric liver transplantation, including waiting list data, transplant, and early and late outcomes. Since 2011, data collection of the current registry has been refined to focus on prospective data and outcomes only after transplant to serve as a foundation for the future development of targeted clinical studies. OBJECTIVE To report the outcomes of the SPLIT registry from 2011 to 2018. METHODS This is a multicenter, cross-sectional analysis characterizing patients transplanted and enrolled in the SPLIT registry between 2011 and 2018. All patients, <18 years of age, received a first liver-only, a combined liver-kidney, or a combined liver-pancreas transplant during this study period. RESULTS A total of 1911 recipients from 39 participating centers in North America were registered. Indications included biliary atresia (38.5%), metabolic disease (19.1%), tumors (11.7%), and fulminant liver failure (11.5%). Greater than 50% of recipients were transplanted as either Status 1A/1B or with a MELD/PELD exception score. Incompatible transplants were performed in 4.1%. Kaplan-Meier estimates of 1-year patient and graft survival were 97.3% and 96.6%. First 30 days of surgical complications included reoperation (31.7%), hepatic artery thrombosis (6.3%), and portal vein thrombosis (3.2%). In the first 90 days, biliary tract complications were reported in 13.6%. Acute cellular rejection during first year was 34.7%. At 1 and 2 years of follow-up, 39.2% and 50.6% had normal liver tests on monotherapy (tacrolimus or sirolimus). Further surgical, survival, allograft function, and complications are detailed.

Abstract
Intestine transplantation is the least common form of organ transplantation in the United States and often deemed one of the most difficult. Patient and graft survival have historically trailed well behind other organ transplants. Over the past 5-10 years registry reports and single center series have demonstrated improvements to patient survival after intestinal transplantation that now match patient survival for those without life-threatening complications on parenteral nutrition. For various reasons including improvements in medical care of patients with intestinal failure and difficulty accessing transplant care, the actual number of intestine transplants has declined by 25% over the past 6 years. In light of the small numbers of intestine transplants, many physicians and the lay public are often unaware that this is a therapeutic option. The aim of this review is to describe the current indications, outcomes and advances in the field of intestine transplantation and to explore concerns over future access to this important and life-saving therapy.

Abstract
In a 24-month prospective, randomized, multicenter, open-label study, de novo liver transplant patients were randomized at 30 days to everolimus (EVR) + Reduced tacrolimus (TAC; n = 245), TAC Control (n = 243) or TAC Elimination (n = 231). Randomization to TAC Elimination was stopped prematurely due to a significantly higher rate of treated biopsy-proven acute rejection (tBPAR). The incidence of the primary efficacy endpoint, composite efficacy failure rate of tBPAR, graft loss or death postrandomization was similar with EVR + Reduced TAC (10.3%) or TAC Control (12.5%) at month 24 (difference -2.2%, 97.5% confidence interval [CI] -8.8%, 4.4%). BPAR was less frequent in the EVR + Reduced TAC group (6.1% vs. 13.3% in TAC Control, p = 0.010). Adjusted change in estimated glomerular filtration rate (eGFR) from randomization to month 24 was superior with EVR + Reduced TAC versus TAC Control: difference 6.7 mL/min/1.73 m(2) (97.5% CI 1.9, 11.4 mL/min/1.73 m(2), p = 0.002). Among patients who remained on treatment, mean (SD) eGFR at month 24 was 77.6 (26.5) mL/min/1.73 m(2) in the EVR + Reduced TAC group and 66.1 (19.3) mL/min/1.73 m(2) in the TAC Control group (p < 0.001). Study medication was discontinued due to adverse events in 28.6% of EVR + Reduced TAC and 18.2% of TAC Control patients. Early introduction of everolimus with reduced-exposure tacrolimus at 1 month after liver transplantation provided a significant and clinically relevant benefit for renal function at 2 years posttransplant.

Abstract
In a prospective, multicenter, open-label study, de novo liver transplant patients were randomized at day 30±5 to (i) everolimus initiation with tacrolimus elimination (TAC Elimination) (ii) everolimus initiation with reduced-exposure tacrolimus (EVR+Reduced TAC) or (iii) standard-exposure tacrolimus (TAC Control). Randomization to TAC Elimination was terminated prematurely due to a higher rate of treated biopsy-proven acute rejection (tBPAR). EVR+Reduced TAC was noninferior to TAC Control for the primary efficacy endpoint (tBPAR, graft loss or death at 12 months posttransplantation): 6.7% versus 9.7% (-3.0%; 95% CI -8.7, 2.6%; p<0.001 for noninferiority [12% margin]). tBPAR occurred in 2.9% of EVR+Reduced TAC patients versus 7.0% of TAC Controls (p = 0.035). The change in adjusted estimated GFR from randomization to month 12 was superior with EVR+Reduced TAC versus TAC Control (difference 8.50 mL/min/1.73 m(2) , 97.5% CI 3.74, 13.27 mL/min/1.73 m(2) , p<0.001 for superiority). Drug discontinuation for adverse events occurred in 25.7% of EVR+Reduced TAC and 14.1% of TAC Controls (relative risk 1.82, 95% CI 1.25, 2.66). Relative risk of serious infections between the EVR+Reduced TAC group versus TAC Controls was 1.76 (95% CI 1.03, 3.00). Everolimus facilitates early tacrolimus minimization with comparable efficacy and superior renal function, compared to a standard tacrolimus exposure regimen 12 months after liver transplantation.

Abstract
BACKGROUND Minimally invasive surgical techniques decrease the length of hospitalization and the morbidity for general surgery procedures. Application of minimally invasive techniques to obesity surgery had previously been limited to stapled techniques used primarily for the Roux-en-Y gastric bypass and laparoscopic band placement. The authors present the technique for totally intracorporeal robotically assisted biliary pancreatic diversion with a duodenal switch (BPD/DS) using five ports. METHODS After development of the technique in animal and human cadaver models, the da Vinci robot was first used in October 2000 to perform BPD/DS using five ports and a totally intracorporeal technique. Patient selection was based on standard surgery guidelines for the morbidly obese. RESULTS This technique was applied for 47 patients with a mean body mass index (BMI) of 45 kg/m2 and a mean age of 38 +/- 10 years. The median operating time was 514 min (range, 370-931 min). The median operative time for the last 10 patients was 379 min (range, 370-582 min). Three patients underwent conversion to open surgery, and four patients experienced postoperative leaks with no mortality. CONCLUSION The safety, feasibility, and reproducibility of a minimally invasive robotic surgical approach to complex abdominal operations such as BPD/DS is demonstrated. The BPD/DS allows for a sutured bowel anastomosis similar to the open technique using a minimal number of small access ports.

Abstract
A high incidence of aneurysms of the splenic artery is found in liver transplant patients. Their significance is related to the risk of rupture, particularly in the postoperative period. Classically, their management is surgical, with ligation or resection of the aneurysmal arterial segment with or without splenectomy, depending on the location of the aneurysm. Recently, laparoscopy and percutaneous embolization have appeared as alternative treatment options. We describe here the treatment of multiple aneurysms of the splenic artery in a patient who had undergone liver transplantation 10 years earlier. She was treated with percutaneous embolization of the aneurysms followed by laparoscopic splenectomy. To our knowledge, this is the first report of laparoscopic splenectomy following liver transplantation. It demonstrates that prior liver transplantation does not represent an absolute contraindication to minimally invasive surgery.

Abstract
BACKGROUND Until recently, conventional intracoronary stent deployment required predilatation of the lesion with a balloon. However, "direct stenting" of the lesion without predilatation offers certain theoretical and practical advantages. We assessed the safety and feasibility of direct stenting in a select group of patients who were likely to benefit most from these advantages, namely, those with acute coronary syndromes. saphenous vein graft lesions, associated renal or left ventricular dysfunction and those requiring multivessel intervention. METHODS AND RESULTS After direct stenting, intravascular ultrasound was used to assess the adequacy of stent expansion in 51 patients. One hundred and twenty patients with a total of 125 lesions (83.3% males, average age 54.6+/-12.4 years) were enrolled for direct stenting. Of these, 90% of patients had presented with acute coronary syndromes, 21.6% of patients had associated moderate-to-severe left ventricular systolic dysfunction, 6.7% of patients had associated renal dysfunction and 30.8% of patients required multivessel intervention. Angiographically visible thrombus was present in 35.2% of patients. The mean reference diameter of the lesion was 3.18+/-0.32 mm and mean percentage diameter stenosis was 76.4+/-11.2%. Almost all varieties of stents were used (8.8% bare and 91.2% mounted). Procedural success was achieved in 98.3% of patients (98.4% of lesions). In two cases, the lesion had to be predilated prior to stenting. On angiography, the need for postdilatation of the stent was apparent in 29 (23.6%) lesions. In contrast, on intravascular ultrasound evaluation done in 51 lesions after stent deployment, the need for postdilatation to optimize stent expansion was seen in 43 (84.3%) lesions. There was one instance of acute stent thrombosis and two instances of slow-flow phenomenon. There were no deaths, myocardial infarction or need for urgent bypass surgery. CONCLUSIONS We conclude that direct stenting is feasible and safe in selected groups of patients. Optimization of stent expansion after direct stenting may often require aggressive postdilatation.

Abstract
Intestinal transplantation is an established life-saving therapy for parenteral nutrition dependent patients suffering from severe complications of parenteral nutrition. Improvements in outcomes over the last decade have occurred with refinements in surgical technique, better immunosuppressive regimens, and clinical experience. The long-term results of intestinal transplantation are not well known and morbidity remains an important obstacle to wider application of this procedure to patients with short bowel syndrome (SBS). This article reviews the indications for intestinal transplantation, the evaluation of potential candidates, therapeutic considerations, postoperative management and common complications experienced by the recipients.

Abstract
PURPOSE The aim of this study was to determine long-term results of intestinal transplantation in children with pseudo-obstruction, particularly when stomach and colon are not part of the allograft. METHODS The authors conducted a case-record review of all children who underwent transplantation at our center for a primary diagnosis of pseudo-obstruction. Supplementary information was obtained from outpatient charts, computerized database, and telephone survey of parents. RESULTS Six small bowel and 3 liver-small bowel transplants were carried out in 8 patients between 1993 and 1999. Median follow-up is 40 months (range, 13 to 73 months). Median age at transplantation was 2.7 years (range, 0.7 to 12.8 years). Median graft survival in this series is 15 months (range, 1 day to 71 months). Stomach and colon were excluded from all allografts. Two children died 5 and 368 days after transplant and 2 graft losses occurred in 1 patient. Two children had lymphoproliferative disease; both are alive with functioning grafts. Five survivors with functioning grafts receive full enteral feedings at home. Four of the 5 have had ileostomies closed, and 3 have normal bowel movements. CONCLUSIONS Intestinal transplantation without stomach or colon provides children with chronic intestinal pseudo-obstruction with a good quality of life. The underlying disease poses special challenges in management.

Abstract
The current clinical practice of stent implantation has changed over the last few years. We analysed the incidence and time course of stent thrombosis in patients undergoing successful coronary angioplasty and stenting over the last three years. All the patients were treated with aspirin and ticlopidine. A total of 13 patients experienced stent thrombosis. The mean age was 52+/-12 years; 12 were smokers and 10 had a recent history of myocardial infarction. None of these patients had received abciximab. The median time from stent implantation to stent thrombosis was 10 hours, with all the stent occlusions occurring within 18 hours of stent implantation procedure. All the patients underwent a repeat intervention at a median time of 30 minutes after the clinical suspicion of stent occlusion. On follow-up of 1 to 24 months, three patients developed reocclusion. In the present era of coronary angioplasty and stenting, when interventional procedures are not pre-planned and patients are treated with aspirin and ticlopidine or clopidogrel at the time of stent implantation, the incidence of stent thrombosis is low; it is seen mainly in patients with recent myocardial infarction, majority of them being smokers, and occurs within 18 hours in all the patients.

Abstract
The purpose of this study was to assess the 1-year clinical outcome of patients with multi-vessel coronary artery disease (CAD) who underwent coronary stenting, and to compare the results with single-vessel coronary stenting carried out during the same period. We evaluated the in-hospital and 12-month clinical outcomes [death, Q-wave myocardial infarction (MI) and repeat revascularization rates at one year] in 384 consecutive patients treated with coronary stents in 2 (92% of patients) or 3 of the native coronary arteries and compared the outcome to 624 consecutive patients undergoing stenting in a single coronary artery between January 1, 1997 and January 31, 1999. The overall procedural success was obtained in 99% of patients with 2- or 3-vessel stenting and 98% of patients with single-vessel stenting. Procedural complications were similar (2.9% vs 2.6%; p = 0.12). During follow-up, target lesion revascularization was 16% in multi-vessel and 14% in single-vessel stenting (p = 0.38) and repeat revascularization was also similar for both groups (19% vs. 20%; p = 0.73). There was no difference in death (0.8% vs. 1.3%; p = 0.31) and Q-wave MI (0.7% vs. 1.4%; p = 0. 16) in the 2 groups. Overall cardiac event-free survival was similar for both groups (76% vs. 78%; p = 0.54). Multi-vessel stenting in carefully selected patients in our experience had a high procedural success with very low complication rates. The one-year clinical outcomes were acceptable and were similar to the results of single-vessel stenting.

Abstract
BACKGROUND The long-term outcome of simultaneous kidney pancreas transplant recipients is not well established. METHODS We retrospectively reviewed all patients who underwent simultaneous kidney-pancreas transplantation with bladder drainage at our center between January 1989 and December 1991. A total of 57 patients (93%) were alive with functioning grafts 1 year after transplantation and were followed for a minimum of 5 years. These patients formed the study group. RESULTS Five-year actual patient, kidney and pancreas survival rates were 95%, 85%, and 88%, respectively. Fasting serum glucose fell from 198 mg/dL preoperatively to 94 mg/dL and remained stable thereafter. Glycohemoglobin levels decreased from 9.8% preoperatively to 4.8% 1 year after transplantation and remained normal thereafter. Kidney function remained good, with mean serum creatinine of 2.0 and creatinine clearance of 56 ml/min throughout the follow-up period. Hospital admissions decreased significantly with increasing time after transplantation from a mean of 1.2 admissions per patient in the 1st year to a mean of 0.2 admissions per patient 6 years after transplantation. Of the readmissions, 42% were for <48 hr and the most common reasons for readmission were infection, surgery, and dehydration. Mean systolic blood pressure decreased from 166 mm Hg before the transplant to 142 mm Hg 1 year after the transplant. CONCLUSIONS Simultaneous kidney pancreas transplantation is a safe and effective method to treat advanced diabetic nephropathy and is associated with stable metabolic function, decreased cholesterol, improved hypertension control, improved rehabilitation over time, and little morbidity or mortality after the 1st year.

Abstract
OBJECTIVES In symptomatic and asymptomatic patients with significant carotid artery stenosis, surgical endarterectomy has been shown to be beneficial when compared with medical management. Carotid stenting is evolving as an alternative technique for treating such patients. This prospective study was designed to assess the feasibility and safety of carotid angioplasty and stenting. METHODS Fourteen patients (15 carotid arteries) with significant carotid artery stenosis were enrolled. These patients were in the age range 46 to 84 years (mean 60.9 +/- 7 years) and there were 12 males (86%). All of these patients were symptomatic with either TIA (n = 8) or stroke (n = 6). Wallstents were used in all the cases to stent the carotid arteries. One patient underwent bilateral carotid artery stenting. RESULTS Carotid angioplasty and stenting was successful in 13 out of 14 (92.8%) patients and 14 out of 15 (93.3%) carotid arteries, with reduction in mean (+/- SD) stenosis from 86 +/- 6% to 3 +/- 3%. There was one episode of minor stroke, no major stroke or death during the initial hospitalization. Another patient had a minor stroke with patent ipsilateral carotid artery (on repeat angiography) during the first 30 days after the procedure. This patient was also found to have asymptomatic thrombus formation in the contralateral carotid stent which resolved with intravenous anticoagulation. During a mean follow up of 6 +/- 2 months there has been no recurrence of symptoms. CONCLUSIONS Based upon our limited experience we believe that percutaneous carotid angioplasty with stenting is feasible with low periprocedural complication rate.

Abstract
Surgical transmyocardial laser revascularization has been reported to improve clinical outcome in patients with refractory angina who are not candidates for angioplasty or bypass surgery. We investigated the feasibility and safety of a nonsurgical, percutaneous technique for laser channel creation using energy from a holmium:yttrium-aluminium-garnet (YAG) laser. The laser energy was directed through a fiber enclosed in a catheter to the ventricular myocardium creating channels between the blood pool and the myocardium. Thirty-five patients with angina and coronary anatomy not amenable to revascularization with coronary angioplasty or bypass surgery underwent percutaneous transluminal myocardial revascularization. A total of 15 +/- 5 channels were formed per patient. There was no procedure-related mortality. One patient developed cardiac tamponade requiring thoracotomy and another a minor self-limiting pericardial effusion. There was no worsening of regional wall motion function in any patient. All patients were discharged alive after a postprocedure hospital stay of 2.1 +/- 1.4 days. Mean Canadian Cardiovascular Society (CCS) functional class declined from 3.68 +/- 0.4 before procedure to 0.82 +/- 0.7 at 30 days (P < 0.01). At 3 months, mean angina class was 0.94 +/- 0.65 (n = 35; P < 0.01) and at 6 months, mean angina class was 1.08 +/- 0.58 (n = 26; P < 0.01). One patient required repeat revascularization after 5 months for progression of disease in a degenerated saphenous venous graft supplying different region of myocardium. We conclude that transmyocardial revascularization using holmium:YAG laser by percutaneous technique can be carried out safely with encouraging early results and a very low complication rate. The symptomatic relief seen up to 6 months has been excellent. The long-term effects of this technique on mortality and relief of angina, however, remain to be defined. Cathet. Cardiovasc.

Abstract
Primary coronary stenting is being increasingly used in patients undergoing primary coronary angioplasty for acute myocardial infarction. In this prospective study we evaluated our experience of direct angioplasty in 68 patients with acute myocardial infarction of whom 57 received intracoronary stents using high-pressure deployment (> or =12 atmospheres) with adjunct aspirin and ticlopidine therapy without coumadin. All patients underwent pre-discharge follow-up angiography. Stent implantation was successful in all patients. Stent thrombosis was not seen in any patient. However, TIMI grade 3 flow was obtained in only 51 patients (89.6%) with evidence of slow flow present in remaining six patients. Follow-up angiograms showed no stent thrombosis but five out of the six patients (83%) with slow-flow phenomenon persisted to have slow flow. These patients had lower left ventricular ejection fraction as compared to patients with TIMI 3 flow at follow-up angiography (27.5 +/- 10.2% vs. 42.1 +/- 15.2%, P < .001) and a high mortality (two out of six) within 30 days. Primary stenting is safe and feasible in the majority of patients with good short-term outcomes, but persistent slow-flow phenomenon with adverse clinical outcome is seen in a small but significant number of patients.

Abstract
Intraarterial injection of absolute ethanol was employed for the management of a pseudoaneurysm following percutaneous nephrolithotomy. The ethanol was delivered selectively using a coronary angioplasty catheter. This seems to be a potentially useful method for the management of severe hematuria following percutaneous renal procedures.

Abstract
We report the case of a forty-six-year-old female with symptomatic WPW syndrome. The accessory pathway was located on the left free wall, for which ablation was attempted from the retrograde aortic approach. The ablation catheter was positioned at the appropriate site on the mitral anulus. A single radiofrequency energy application resulted in complete AV block with no escape rhythm, necessitating ventricular pacing. The AV conduction soon resumed with no evidence of pre-excitation. This phenomenon was thought to be related to trauma to the AV node during catheter entry in to the left ventricle.

Abstract
OBJECTIVE To review a single center's 10-year experience with liver transplantation (LTx) for the biliary atresia-polysplenia syndrome (BA-PS) and to define surgical and clinical guidelines for its management. SUMMARY BACKGROUND DATA BA is the most common indication for pediatric liver transplantation (LTx) and is associated with PS in 12% of cases. Only a few studies of LTx for BA-PS have been reported, and the optimal management of BA-PS patients undergoing LTx has yet to be determined. METHODS From July 1985 to September 1995, 166 liver transplants were performed in 130 patients with BA and were included in the study. The malformations most commonly associated with BA-PS, surgical techniques used to overcome these anomalies, and surgical pitfalls that could have contributed to the outcome were characterized. Actuarial 10-year patient and graft survival for patients undergoing LTx for BA-PS were calculated and compared to those with isolated BA. RESULTS Ten patients (7.8%) with BA had associated PS. An additional patient with PS without BA was included in the study. The diagnosis of PS was unknown before the transplantation in 72% of cases. Thirteen liver transplants were performed in these 11 patients. Modifications of the usual surgical technique were used to overcome the complex anatomy encountered. There was no association between the type of anomaly and the outcome, nor were there any significant differences in patient survival (72% vs. 73.5%, p = 0.79) or graft survival (56.4% vs. 54.6%, p = 0.54). CONCLUSIONS The association of BA with various anomalies should be considered a spectrum that may vary widely from patient to patient. The finding of two or more of these malformations in a patient awaiting transplantation should lead the surgeon to look systematically for other associated anomalies. With some special surgical considerations, the outcome in BA-PS patients should not differ from those with isolated BA.

Abstract
BACKGROUND Retransplantation has been considered a risk factor for both postoperative complications and diminished graft survival, especially in diabetic patients. METHODS A retrospective survey was performed of a consecutive case series of 196 pancreas transplants in 186 diabetic patients. All patients underwent whole organ pancreas transplantation with bladder drainage. RESULTS A total of 33 pancreas transplants (17%) in 30 patients were performed after previous transplant. The mean interval between transplants was 3.9 years. At the time of retransplantation, 16 patients had concomitant procedures. Venous extension grafts were used in 10 patients. The mean length of initial hospital stay was 19.5 days, and mean hospital charges were approximately $125,000. The incidences of rejection, infection, and operative complications were 61%, 67%, and 45%, respectively. Patient survival was 90%, kidney graft survival was 82%, and pancreas graft survival was 61% after a mean follow-up of 29 months. Complete rehabilitation was achieved in 73% of cases. CONCLUSIONS Pancreas transplantation after previous transplant is a challenging but safe treatment that often requires concomitant procedures, the use of vascular extension grafts, and atypical placement of the allograft. However, the good results justify an aggressive policy of retransplantation in the diabetic patient either with a failed allograft or functioning kidney transplant.

Abstract
Bladder drainage by the duodenal segment (DS) technique is currently the preferred method of pancreas transplantation (PTX) but is associated with unique complications. Over a 7-year period, 191 diabetic patients underwent 201 whole-organ PTXs with bladder drainage using a 6 to 8 cm length of DS as an exocrine conduit. A retrospective chart review was performed to document all DS morbidity. DS complications occurred in 38 cases (19%). Twelve patients developed DS leaks and required operative repair. DS bleeding was documented in 26 cases, necessitating cystoscopy in 22 patients and open repair in eight patients for significant hematuria. Cytomegalovirus (CMV) duodenitis was diagnosed in seven cases, with four presenting as DS leaks and three with hematuria. Five patients experienced ampullary obstruction early after PTX. Rejection of the DS was confirmed by biopsy in 13 patients, including eight cases of acute and five cases of chronic rejection. Two patients had stone formation from the DS staple line. Enteric conversion was performed in five patients for DS abnormalities (leaks in 2 cases, bleeding in 2, and CMV duodenitis in 1). Among patients with DS complications, patient survival is 84% and pancreas graft survival is 68% after a mean follow-up of 44+/-12 months. Complications related to the DS remain an important source of morbidity but rarely cause death after PTX. In spite of unique side effects, transplantation of the DS remains an acceptable alternative for exocrine drainage after PTX.

Abstract
UNLABELLED Whole organ pancreaticoduodenal transplantation with bladder drainage by the duodenal segment technique is currently the preferred method of vascularized pancreas transplantation but is associated with a finite risk of surgical complications. Meticulous bench reconstruction of the pancreaticoduodenal allograft may minimize complications following transplantation. Over a 6.5-yr period, 192 pancreas transplants were performed in 181 diabetic patients by the same transplant team. A retrospective review was performed in order to describe a stepwise approach to bench preparation of the pancreaticoduodenal allograft that has developed from this experience. In this series of 192 consecutive pancreaticoduodenal reconstructions, no procured pancreas was deemed non-usable solely from an anatomic standpoint. The mean backtable pancreas preparation time was 2 h. The operative complication rate 19%, the incidence of technical graft loss was 6.8%, and there was no mortality related to technical problems. CONCLUSIONS Using a standardized approach, meticulous bench reconstruction of the pancreaticoduodenal allograft: 1) can be performed in virtually any anatomic setting; 2) decrease complications following transplantation; 3) improves initial allograft function; and 4) minimizes organ wastage.

Abstract
OBJECTIVE To determine the safety and efficacy of solitary pancreas transplantation in the treatment of IDDM. RESEARCH DESIGN AND METHODS A single-center retrospective case series of 62 consecutive solitary pancreas transplants (20 sequential pancreas after kidney, 42 pancreas transplants alone) performed in 57 adult IDDM patients was studied. Indications for solitary pancreas transplantation were 1) the presence of two or more overt diabetic complications and/or 2) glucose hyperlability with hypoglycemic unawareness and impaired quality of life. The recipient group consisted of 31 men and 26 women with a mean age of 38 years (range 25-62) and a mean duration of diabetes of 26 years (range 14-52). Mean pretransplant glycohemoglobin level was 9.9 +/- 2.6%. Organ acceptance was restricted to ideal donors and man-dated a minimum of a two-antigen match (mean human leukocyte antigen ABDR match 2.7). The mean cold ischemia time was 16.6 h. Whole-organ pancreas transplantation was performed with bladder drainage by the duodenal segment technique. All patients were managed with either triple or quadruple immunosuppression. Monitoring included prospective urine cytology as well as cystoscopic transduodenal needle biopsies. RESULTS The mean length of initial hospital stay was 18 days, and mean hospital charges were $106,341. The incidences of rejection, infection, and surgical complications were 70, 55, and 47%, respectively. Overall patient and graft survival rates were 86 and 52%, respectively, with a mean follow-up of 28 months. All patients with functioning grafts had excellent metabolic control (mean glycohemoglobin level 5.1%) and achieved good rehabilitation. CONCLUSIONS Despite morbidity, solitary pancreas transplantation can be performed with improving success, can enhance quality of life, and can offer an opportunity to arrest secondary diabetic complications.

Abstract
BACKGROUND Bladder drainage by the duodenal segment technique is currently the preferred method of handling the exocrine secretions after vascularized pancreatic transplantation. Despite improving results, however, the management of metabolic and urologic complications associated with bladder drainage remains problematic. STUDY DESIGN A retrospective survey was performed of a consecutive case series of 196 pancreatic transplantations in 186 patients with diabetes over an 80-month period. All patients underwent whole organ pancreatic transplantation with bladder drainage by the duodenal segment technique. RESULTS A total of 25 conversions (13 percent) from bladder drainage to enteric drainage were performed in 24 patients (24 side-to-side duodenoenterostomies, one Roux-en-Y limb duodenoenterostomy). The mean time of enteric conversion after pancreatic transplantation was 22 +/- 18 months (range, 1 to 72 months). All but two of the enteric conversions were performed at least 6 months after pancreatic transplantation. Indications for enteric conversion included dehydration with intractable metabolic acidosis (n = 18; 9 percent), urologic complications (n = 5; 3 percent), or problems with the duodenal segment (n = 2; 1 percent). The mean length of hospitalization for enteric conversion was 12 +/- 7 days (range, 6 to 30 days). All patients experienced improvement in their symptoms after enteric conversion. Anastomotic leaks developed postoperatively in five patients; two were managed operatively and three were managed nonoperatively. Oral bicarbonate supplementation was eliminated in all but one patient after enteric conversion. Patient survival is 100 percent and pancreatic graft survival (insulin independence) is 96 percent after a mean follow-up of 22 months after enteric conversion. CONCLUSIONS Enteric conversion after pancreatic transplantation with bladder drainage is a safe and effective therapy for refractory problems related to the duodenal segment, altered physiologic function, or urologic complications and should be considered after 6 months for patients with persistent side effects.

Abstract
Combined pancreas-kidney transplantation (PKT) has become generally accepted as an effective treatment option, but controversy exists regarding the early morbidity rate of the procedure. To address this issue, we retrospectively analyzed all readmissions occurring in the first 3 months after PKT. Over a 5-year period, we performed 98 PKTs with bladder drainage. The mean recipient age was 36.6 years, with a mean pretransplant duration of diabetes of 23.5 years. All patients received quadruple immunosuppression with antilymphocyte induction therapy. The mean length of initial hospital stay was 20 days. One hundred forty-five readmissions occurred in 73 patients (74.5%), with the initial readmission occurring at a mean of 8.5 days after hospital dismissal and 28 days after PKT. Twenty-five patients (25.5%) had no readmissions, 35 (36%) had one readmission, 17 (17%) had two readmissions, and the remaining 21 patients (21.5%) had three or more readmissions in the first 3 months. The mean number of readmissions was 1.5 per patient. Forty-seven patients (48%) were readmitted within 1 week, and all but one initial readmission occurred within 1 month of hospital dismissal. Causes of readmission included rejection (51), infection (32), pancreas-specific morbidity (such as dehydration, hematuria, or pancreatitis; 50), and miscellaneous causes (12). Thirteen patients (13%) underwent reoperation during readmission. The mean length of hospital stay during readmission was 7.6 days. The mean total length of hospitalization in the first 3 months after PKT was 31 days. Over the span of 5 years, no changes have occurred either in the incidence, timing, causes, or duration of readmissions. The patient survival rate is 96%, the kidney graft survival rate is 90%, and the pancreas graft survival rate is 88% after a mean follow-up of 2.6 years. Mean rehabilitation time (return to work or normal activity) after PKT was 4.0 months. In conclusion, PKT is associated with a fixed morbidity characterized by early readmission (within 1 week) in nearly half of patients and pancreas-specific morbidity as the cause in 35% of readmissions. During evaluation, prospective candidates should be counseled regarding the unique morbidity of PKT. Successful management strategies must emphasize the intensity of early follow-up and recognize the propensity toward immunologic, metabolic, exocrine, and urologic side effects.

Abstract
The early detection of allograft rejection remains elusive after solitary pancreas transplantation (PTX). We have previously described a modified technique of cystoscopic transduodenal PTX biopsy using the Biopty gun under ultrasound guidance. During the last 2 years, we performed 24 solitary PTXs with prospective protocol biopsy monitoring as well as biopsies performed whenever clinically indicated. The study group included 17 pancreas transplants alone, 6 sequential pancreas after kidney transplants, and 1 sequential pancreas after liver transplant. Five patients received pancreas retransplants. A total of 92 cystoscopically directed core PTX biopsies were performed, including 50 protocol biopsies (mean 2.1 per patient). Protocol biopsies were performed at 1 month (19), 2 months (3), 3 months (20), 6 months (7), and 12 months (1) after PTX. Adequate PTX tissue for histopathologic examination was obtained in 49 cases (98%). Biopsy findings included no rejection (34), mild rejection (13), pancreatitis (1), and cytomegalovirus infection (1). Overall, 15 of the 49 evaluable biopsies (31%) had significant histopathologic findings. All but 1 of the cases of mild rejection were treated with bolus steroids. Eight of these patients subsequently developed recurrent biopsy-proven rejection within 2 months; 5 grafts were subsequently lost to rejection between 3 and 13 months after PTX. Three biopsy complications occurred: 1 hematoma, 1 pancreatitis, and 1 ileus. Patient survival is 96% and PTX graft survival (complete insulin independence) is 75% after a mean follow-up of 15 months. In the remaining 42 clinically indicated biopsies, 3 were insufficient, 8 showed no rejection, and 31 (79%) had rejection. In half of these cases, the rejection was graded as moderate to severe. In conclusion, prospective monitoring with protocol PTX biopsies may result in the earlier detection of allograft rejection and have a direct effect on improving results after solitary PTX.
