Abstract
The Banff pancreas working schema for diagnosis and grading of rejection is widely used for treatment guidance and risk stratification in centers that perform pancreas allograft biopsies. Since the last update, various studies have provided additional insight regarding the application of the schema and enhanced our understanding of additional clinicopathologic entities. This update aims to clarify terminology and lesion description for T cell-mediated and antibody-mediated allograft rejections, in both active and chronic forms. In addition, morphologic and immunohistochemical tools are described to help distinguish rejection from nonrejection pathologies. For the first time, a clinicopathologic approach to islet pathology in the early and late posttransplant periods is discussed. This update also includes a discussion and recommendations on the utilization of endoscopic duodenal donor cuff biopsies as surrogates for pancreas biopsies in various clinical settings. Finally, an analysis and recommendations on the use of donor-derived cell-free DNA for monitoring pancreas graft recipients are provided. This multidisciplinary effort assesses the current role of pancreas allograft biopsies and offers practical guidelines that can be helpful to pancreas transplant practitioners as well as experienced pathologists and pathologists in training.

Abstract
The First World Consensus Conference on Pancreas Transplantation provided 49 jury deliberations regarding the impact of pancreas transplantation on the treatment of diabetic patients, and 110 experts' recommendations for the practice of pancreas transplantation. The main message from this consensus conference is that both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone can improve long-term patient survival, and all types of pancreas transplantation dramatically improve the quality of life of recipients. Pancreas transplantation may also improve the course of chronic complications of diabetes, depending on their severity. Therefore, the advantages of pancreas transplantation appear to clearly surpass potential disadvantages. Pancreas after kidney transplantation increases the risk of mortality only in the early period after transplantation, but is associated with improved life expectancy thereafter. Additionally, preemptive SPK, when compared to SPK performed in patients undergoing dialysis, appears to be associated with improved outcomes. Time on dialysis has negative prognostic implications in SPK recipients. Increased long-term survival, improvement in the course of diabetic complications, and amelioration of quality of life justify preferential allocation of kidney grafts to SPK recipients.

Abstract
BACKGROUND Early vascular complications following pancreatic transplantation are not uncommon (3%-8%). Typically, cross-sectional imaging is requested in response to clinical change. We instituted a change in protocol to request imaging pre-emptively to identify patients with thrombotic complications. METHODS In 2013, protocol computer tomography angiography (CTA) at days 3-5 and day 10 following pancreas transplantation was introduced. A retrospective analysis of all pancreas transplants performed at our institution from January 2001 to May 2019 was undertaken. RESULTS A total of 115 patients received pancreas transplants during this time period. A total of 78 received pancreas transplant without routine CTA and 37 patients with the new protocol. Following the change in protocol, we detected a high number of subclinical thromboses (41.7%). There was a significant decrease in invasive intervention for thrombosis (78.6% before vs 30.8% after, p = .02), and graft survival was significantly higher (61.5% before vs 86.1% after, p = .04). There was also a significant reduction in the number of graft failures (all-cause) where thrombosis was present (23.4% before vs 5.6% after, p = .02). Patient survival was unaffected (p = .48). CONCLUSIONS Implementation of early protocol CTA identifies a large number of patients with subclinical graft thromboses that are more amenable to conservative management and significantly reduces the requirement for invasive intervention.

Enteric Conversion of Bladder-drained Pancreas as a Predictor of Outcomes in Almost 600 Recipients at a Single Center. Transplant Direct 2020; 6:e550. [PMID: 32548244 PMCID: PMC7213611 DOI: 10.1097/txd.0000000000000997] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 03/10/2020] [Accepted: 03/23/2020] [Indexed: 01/12/2023] Open
Abstract
Complications associated with bladder-drained pancreata necessitating enteric conversion are common. Data on the outcomes after enteric conversion are conflicting. We studied the association between enteric conversion and the pancreas graft rejection, loss, and mortality. Methods At our center, 1117 pancreas transplants were performed between 2000 and 2016. We analyzed 593 recipients with bladder-drained pancreata, of which 523 received solitary transplants and 70 received simultaneous pancreas-kidney transplants. Kaplan-Meier function was used to estimate time to conversion by transplant type. Cox proportional hazards models were utilized to evaluate patient survival, death-censored graft survival, and acute rejection-free survival while treating conversion as a time-dependent covariate. Subsequently, we examined the association between timing of conversion and the same outcomes in the conversion cohort. Results At 10 y posttransplant, 48.8% of the solitary pancreas recipients and 44.3% of simultaneous pancreas-kidney transplant recipients had undergone enteric conversion. The enteric conversion was associated with 85% increased risk of acute rejection (hazard ratio [HR] = 1.85; 95% confidence interval [CI] = 1.37-2.49; P < 0.001). However, the conversion was not associated with graft loss or mortality. In the conversion cohort, a longer interval from engraftment to conversion was associated with an 18% lower rejection rate (HR = 0.82; 95% CI = 0.708-0.960; P = 0.013) and a 22% better graft survival (HR = 0.78; 95% CI = 0.646-0.946; P = 0.01). Conclusions Enteric conversion was associated with increased risk of rejection, but not increased risks of graft loss or mortality. The decision to convert should consider the increased rejection risk. A longer interval from engraftment to conversion appears favorable.

Abstract
In December 1966, the first pancreas transplant ever was performed at the University of Minnesota. R. Lillehei and W. Kelly, transplanted a kidney and a pancreas in a diabetic patient on dialysis, getting function of both organs. Since then, the technical and immunological advances in this transplant have resulted in graft and patient survival results as the rest of the abdominal solid organ transplants. The balance of these 50 years is that more than 50,000 diabetic patients have been transplanted in more than 200 centers around the world. In our country the first transplant was performed 34 years ago in Barcelona and now 12 centers perform about 100 transplants per year. Although advances in diabetes control have been very important, pancreas transplantation continues to be the only method that allows normalization of the carbohydrates metabolism to improve the quality of life and, above all, to increase the survival of these patients.

Abstract
Graft survival after pancreas transplantation alone (PTA) is significantly poorer than graft survival after simultaneous pancreas kidney (SPK) and is particularly affected by difficulty in monitoring rejection. Exocrine bladder drainage allows assessment of pancreas graft function as urinary amylase (UA). However, standards for UA collection and interpretation are not well defined. In this study, 21 bladder-drained PTA recipients were monitored with daily values for UA and urine creatinine (Creat) concentration from post-transplant 10-mL samples and 24-h collections. Clinical events were documented and correlated to UA measurements. UA values were found to increase post-transplant until day 15, and large interpatient variability was noted (median 12 676 IU/L, range 668-60 369 IU/L). A strong correlation was found total 24-h UA production and spot UA/Creat ratio (r = 0.80, p < 0.001). UA/Creat ratio showed less variation during episodes of impaired renal function; therefore, urinary amylase baseline was defined as the median UA/Creat ratio after day 15. A > 25% decrease of UA predicted 9/13 (69%) events. We conclude that individual baselines should be set once the values have stabilized after 15 d post-transplant and that spot UA/Creat measures are reliable, patient friendly and indicate potential events after PTA.

Abstract
Several exocrine drainage procedures have been successfully developed to perform pancreas transplantation (PT). Retroperitoneal graft placement allows exocrine drainage via direct duodenoduodenostomy (DD). This technique provides easy access for endoscopic surveillance and biopsy. A total of 241 PT procedures were performed in our centre between 2002 and 2012. DD was performed in 125 patients, and duodenojejunostomy (DJ) in 116 patients. We retrospectively compared our experience with these two types of enteric drainage, focusing on graft and patient survivals, as well as postoperative complications. With a mean follow-up of 59 months, both groups demonstrated comparable patient and graft survivals. 14 (11%) of 125 cases in the DD group and 21 (18%) of 116 cases in the DJ group had pancreatic graft loss (P = 0.142). Graft thrombosis [5 (4%) vs. 18 (16%) P = 0.002], anastomotic insufficiency [2 (1.6%) vs. 8 (7%) P = 0.052] and relaparotomy [52 (41%) vs. 56 (48%) P = 0.29] occurred more frequently in the DJ group, whereas gastrointestinal bleeding [14 (11%) vs. 4 (3%) P = 0.026] occurred more often in the DD group. DD is a feasible and safe technique in PT, with no increase in enteric complications. It is equivalent to other established techniques and extends the feasibility of anastomotic sites, especially in recipients who have undergone a second transplantation.

Abstract
Since the first pancreas transplants in the early 1960s, whole-organ pancreas transplantation, either alone or combined with kidney transplantation, has become commonplace in many countries around the world. Whole-organ pancreas transplantation is available in the UK, with ~200 transplants currently carried out per year. Patient survival and pancreas graft outcome rates are now similar to other solid organ transplant programmes, with high rates of long-term insulin independence. In the present review, we will discuss whole-pancreas transplantation as a treatment for diabetes, focusing on indications for transplantation, the nature of the procedure performed, graft survival rates and the consequences of pancreas transplantation on metabolic variables and the progression of diabetes-related complications.

Abstract
Transplantation of the pancreas, either as a solid organ or as isolated islets of Langerhans, is indicated in a small proportion of patients with insulin-dependent diabetes in whom severe complications develop, particularly severe glycemic instability and progressive secondary complications (usually renal failure). The potential to reverse diabetes has to be balanced against the morbidity of long-term immunosuppression. For a patient with renal failure, the treatment of choice is often a simultaneous transplant of the pancreas and kidney (SPK), whereas for a patient with glycemic instability, specifically hypoglycemic unawareness, the choice between a solid organ and an islet transplant has to be individual to the patient. Results of SPK transplantation are comparable to other solid-organ transplants (kidney, liver, heart) and there is evidence of improved quality of life and life expectancy, but the results of solitary pancreas transplantation and islets are inferior with respect to graft survival. There is some evidence of benefit with respect to the progression of secondary diabetic complications in patients with functioning transplants for several years.

Abstract
The life expectancy of patients with type 1 diabetes mellitus is inferior to that of patients with some malignancies. Simultaneous pancreas-kidney transplantation is the procedure providing the best survival results among all options of renal replacement therapy. The operative techniques and immunosuppresion have been standardized in the last decade. Although the number of transplantable organs falls behind the need, simultaneous pancreas-kidney transplantation is the method of choice for the eligible patients. The results of the two Hungarian simultaneous pancreas-kidney transplantation programs are in accordance with data published in the international literature.

Abstract
Diabetes mellitus remains one of the leading causes of morbidity and mortality worldwide. According to the Centers for Disease Control and Prevention, approximately 23.6 million people in the United States are affected. Of these individuals, 5-10% have been diagnosed with type 1 diabetes mellitus (TIDM), an autoimmune disease. Although it often appears in childhood, T1DM may manifest at any age. The effects of T1DM can be devastating, as the disease often leads to significant secondary complications, morbidity, and decreased quality of life. Since the late 1960s, surgical treatment for diabetes mellitus has continued to evolve and has become a viable alternative to chronic insulin administration. In this review, the historical evolution, current status, graft efficacy, benefits, and complications of pancreas transplantation are explored.

Abstract
Diabetes mellitus is generally treated with oral diabetic drugs and/or insulin. However, the morbidity and mortality associated with this condition increases over time, even in patients receiving intensive insulin treatment, and this is largely attributable to diabetic complications or the insulin therapy itself. Pancreas transplantation in humans was first conducted in 1966, since when there has been much debate regarding the legitimacy of this procedure. Technical refinements and the development of better immunosuppressants and better postoperative care have brought about marked improvements in patient and graft survival and a reduction in postoperative morbidity. Consequently, pancreas transplantation has become the curative treatment modality for diabetes, particularly for type I diabetes. An overview of pancreas transplantation is provided herein, covering the history of pancreas transplantation, indications for transplantation, cadaveric and living donors, surgical techniques, immunosuppressants, and outcome following pancreas transplantation. The impact of successful pancreas transplantation on the complications of diabetes will also be reviewed briefly.

Abstract
PURPOSE Bladder drainage (BD) of pancreatic transplants is associated with a unique set of complications. We intended to analyze the incidence, indications, complications and long-term results of enteric conversion procedures (EC). METHODS Using a prospective database, 32 EC patients out of 433 simultaneous pancreas-kidney-transplant (SPK) recipients were identified. Graft and patient survival rates were compared with those after primary enteric drainage (ED). RESULTS The mean SPK-EC interval was 5.0 yr, and the mean patient follow-up was 13.8 yr. Indications for EC were genitourinary symptoms (62.5%), duodenal complications (15.6%), graft pancreatitis (12.5%), pyelonephritis (6.3%), and metabolic acidosis (3.1%). All patients reported significant long-term resolution of symptoms. Surgical complications, reoperations, early graft loss, and 30-d mortality occurred in 31.3%, 25.0%, 6.3%, and 3.1% of cases, respectively. Pancreatic graft and patient survival rates at 1, 5, and 10 yr after SPK were comparable between EC patients and ED patients at the same institution. CONCLUSION For the treatment of symptoms associated with BD, EC results in excellent long-term graft function and significant resolution of symptoms even years after SPK. Postoperative morbidity after EC including early reoperation and graft loss, however, has to be considered.

Abstract
A 52-yr-old man presented with hematuria and clot retention. He had undergone simultaneous pancreas-kidney transplantation with exocrine pancreas bladder drainage 16 yr ago. The patient suffered from progressive transplant kidney failure with gradually decreasing urine output and needed hemodialysis every other day. Gross hematuria persisted after removal of all blood clots. Cystoscopy showed multiple small, flat ulcers of the bladder mucosa. Some bled discretely and were coagulated cautiously. However, hematuria was refractory to multiple urological interventions, which eventually necessitated an enteric diversion of the exocrine pancreas. Hematuria ceased following an uneventful postoperative course.

Abstract
Accurate diagnosis and grading of rejection and other pathological processes are of paramount importance to guide therapeutic interventions in patients with pancreas allograft dysfunction. A multi-disciplinary panel of pathologists, surgeons and nephrologists was convened for the purpose of developing a consensus document delineating the histopathological features for diagnosis and grading of rejection in pancreas transplant biopsies. Based on the available published data and the collective experience, criteria for the diagnosis of acute cell-mediated allograft rejection (ACMR) were established. Three severity grades (I/mild, II/moderate and III/severe) were defined based on lesions known to be more or less responsive to treatment and associated with better- or worse-graft outcomes, respectively. The features of chronic rejection/graft sclerosis were reassessed, and three histological stages were established. Tentative criteria for the diagnosis of antibody-mediated rejection were also characterized, in anticipation of future studies that ought to provide more information on this process. Criteria for needle core biopsy adequacy and guidelines for pathology reporting were also defined. The availability of a simple, reproducible, clinically relevant and internationally accepted schema for grading rejection should improve the level of diagnostic accuracy and facilitate communication between all parties involved in the care of pancreas transplant recipients.

Abstract
Simultaneous pancreas-kidney transplantation is an established procedure for patients with type I diabetes and end-stage renal disease. Continuous advances in the operation techniques with consequent reduction of perioperative morbidity and mortality and the introduction of modern immunosuppressive agents improved not only patients but also graft survival and significantly decreased rejection episodes of both kidney and pancreas grafts. Availability of a variety of new immunosuppressants in the clinical routine and increasing experience of the transplant specialists allowed further developments of therapeutic schemes with application of induction and maintenance immunosuppressive protocols. In this article, we summarize the current status of immunosuppressive regimens in simultaneous pancreas and kidney transplantation.

Abstract
The transplant recipient has traded a life-threatening illness for a chronically immunosuppressed state. Subsequent anesthetic management for non-transplant surgical procedures may be challenging. The anesthesia provider must be aware of the degree of post-transplant organ dysfunction and alter anesthesia techniques accordingly. This article reviews the anesthetic concerns for patients who have undergone a variety of organ transplants.

Abstract
Since the first pancreatic allograft in 1966, pancreatic transplantations have been performed by numerous surgical teams throughout the world. Initial results were disappointing with a high percentage of technical failures and rejection. Over-optimistic enthusiasm for islet-cell allografts also retarded the development of pancreatic transplantation. Despite this slow start, results of pancreatic transplantation from 1995 onward have been very satisfactory and equivalent to or even better than the results of other solid organ transplants. This success has been due to better graft selection, improved surgical techniques and preservation solutions, and especially to improvements in immunosuppressive protocols. More than 19,000 pancreatic transplantations have now been performed throughout the world including both combined kidney-pancreas transplantations and pancreas-only transplantations. The most satisfactory results occur in the setting of dialysis-dependent renal failure due to diabetes; simultaneous combined kidney and pancreas transplantation is performed with the total pancreas implanted into the bowel and with venous drainage into the portal system. The long-term risks and constraints of chronic diabetes with renal failure must be weighed against the risks of a complex surgical procedure, significant post-operative complications, and the need for long-term immunosuppressive therapy.

Abstract
The method of exocrine diversion in pancreas allograft continues to be controversial due to the advantages versus disadvantages of bladder versus enteric techniques. Bladder drainage (BD) exposes the patient to urological and metabolic problems that may require conversion to enteric drainage (ED). The purpose of this study was to review our initial experience of conversion from BD to ED for patients who underwent pancreas transplantation originally with bladder diversion. Among 114 pancreas transplantation performed with BD, from January 1996 to April 2003, 60 were simultaneous pancreas-kidney transplantation (SPKT), 35 were pancreas transplantation alone (PA), and 19 were pancreas after kidney transplantations (PAK). Twenty-three (20.2%) cases were excluded due to early death of the patient or the graft, yielding an analyses of 91 patients. Enteric conversion (EC) was performed in 14 (15.4%) patients with a mean follow-up of 15.7 months (range, 3-51 months) after transplantation including 8 (8.8%) SPKT, 4 (4.4%) PAK, and 2 (2.2%) PA. No surgical morbidity or mortality was observed related to EC. All patients had complete resolution of the initial problem with preservation of pancreatic function. EC represents an easy, safe procedure with low morbidity and mortality rates, representing the option of choice for patients with persistent urological or metabolic disturbances.

Abstract
OBJECTIVE To report the urological complications after simultaneous renal and pancreatic transplantation. DESIGN Retrospective study. SETTING Teaching hospital, Italy. SUBJECTS 143 consecutive patients having simultaneous renal and pancreatic transplantation by one of three techniques. 33 segmental pancreas with duct occlusion, 77 whole pancreas with bladder diversion, and 33 enteric diversion with systemic (n = 26) or portal venous drainage (n = 7). Urological complications were related to the pancreatic transplant, to the renal transplant, or unrelated to the transplant. MAIN OUTCOME MEASURES Morbidity. RESULTS After occlusion of the duct and enteric diversion, there were no urological complications related to the pancreatic transplant. On the other hand, among the 77 patients with pancreatic drainage into the bladder, urological complications were common (56/77; 73%). Complications related to the renal transplant were recorded in 6/33 (18%), 26/77 (34%) and 12/33 (36%), respectively. Complications unrelated to the transplant occurred in 6/77 patients (8%) in the bladder drainage group. Five patients after bladder drainage required cystoenteric conversion. CONCLUSIONS Enteric diversion is a safe alternative to bladder diversion and results in significantly fewer urological complications.

Abstract
To date one of the major dilemmas in clinical pancreas transplantation is the lack of a reliable indicator for pancreas rejection. In a consecutive series of 52 patients undergoing simultaneous pancreas and kidney (SPK) transplantation with bladder drainage technique between October 1991 and December 1992 a new test using serial levels of serum human anodal trypsinogen (HAT) was evaluated for its efficacy to detect pancreas rejection. Postoperative baseline levels of HAT were compared to peak HAT values at time of rejection. HAT profiles at time of rejection were calculated and compared to profiles of urinary amylase, serum amylase, fasting blood sugar and serum creatinine. In this series one year patient survival was 97%, graft survival of the pancreas 86% and of the kidney 90%. In 71% of the patients at least one rejection episode occurred. At time of kidney-biopsy proven rejection with a concurrent serum creatinine rise a significant HAT level rise to more than 1000 ng/ml was observed from baseline levels of 200 ng/ml (P < 0.001) indicating kidney and pancreas rejection (73%). Urinary amylase levels decreased in the majority of rejection episodes at the same time from baseline levels to less than 20,000 U/l. In 25% of the rejection episodes a significant serum creatinine rise was observed without a HAT rise or urinary amylase decrease indicating kidney-only rejection, while in 2% a urinary amylase decrease and simultaneous HAT also was observed with a negative kidney biopsy indicating pancreas-only rejection. We feel that increase in HAT levels significantly correlates with pancreas rejection. After SPK, determination of HAT is an additional helpful non-invasive test. In pancreas transplantation alone HAT can be a useful indicator to detect rejection and facilitate timing of a pancreas biopsy and initiation of antirejection treatment.

Abstract
Enteric drainage is a sound surgical technique in SKP, and it avoids the majority of urological as well as metabolic complications. We did not see an increase in intraabdominal complications or of graft loss due to rejection. Intestinal leak is rare and easily managed provided a Roux-Y loop of jejunum is used. Even though the number of patients was small and the follow-up short, the results of the RY group were at least comparable to the BD group. In view of our results, we plan to use this technique in all our future SKP patients.

Abstract
OBJECTIVE To determine outcome in diabetic pancreas transplant recipients according to risk factors and the surgical techniques and immunosuppressive protocols that evolved during a 33-year period at a single institution. SUMMARY BACKGROUND DATA Insulin-dependent diabetes mellitus is associated with a high incidence of management problems and secondary complications. Clinical pancreas transplantation began at the University of Minnesota in 1966, initially with a high failure rate, but outcome improved in parallel with other organ transplants. The authors retrospectively analyzed the factors associated with the increased success rate of pancreas transplants. METHODS From December 16, 1966, to March 31, 2000, the authors performed 1,194 pancreas transplants (111 from living donors; 191 retransplants): 498 simultaneous pancreas-kidney (SPK) and 1 simultaneous pancreas-liver transplant; 404 pancreas after kidney (PAK) transplants; and 291 pancreas transplants alone (PTA). The analyses were divided into five eras: era 0, 1966 to 1973 (n = 14), historical; era 1, 1978 to 1986 (n = 148), transition to cyclosporine for immunosuppression, multiple duct management techniques, and only solitary (PAK and PTA) transplants; era 2, 1986 to 1994 (n = 461), all categories (SPK, PAK, and PTA), predominantly bladder drainage for graft duct management, and primarily triple therapy (cyclosporine, azathioprine, and prednisone) for maintenance immunosuppression; era 3, 1994 to 1998 (n = 286), tacrolimus and mycophenolate mofetil used; and era 4, 1998 to 2000 (n = 275), use of daclizumab for induction immunosuppression, primarily enteric drainage for SPK transplants, pretransplant immunosuppression in candidates awaiting PTA. RESULTS Patient and primary cadaver pancreas graft functional (insulin-independence) survival rates at 1 year by category and era were as follows: SPK, era 2 (n = 214) versus eras 3 and 4 combined (n = 212), 85% and 64% versus 92% and 79%, respectively; PAK, era 1 (n = 36) versus 2 (n = 61) versus 3 (n = 84) versus 4 (n = 92), 86% and 17%, 98% and 59%, 98% and 76%, and 98% and 81%, respectively; in PTA, era 1 (n = 36) versus 2 (n = 72) versus 3 (n = 30) versus 4 (n = 40), 77% and 31%, 99% and 50%, 90% and 67%, and 100% and 88%, respectively. In eras 3 and 4 combined for primary cadaver SPK transplants, pancreas graft survival rates were significantly higher with bladder drainage (n = 136) than enteric drainage (n = 70), 82% versus 74% at 1 year (P =.03). Increasing recipient age had an adverse effect on outcome only in SPK recipients. Vascular disease was common (in eras 3 and 4, 27% of SPK recipients had a pretransplant myocardial infarction and 40% had a coronary artery bypass); those with no vascular disease had significantly higher patient and graft survival rates in the SPK and PAK categories. Living donor segmental pancreas transplants were associated with higher technically successful graft survival rates in each era, predominately solitary (PAK and PTA) in eras 1 and 2 and SPK in eras 3 and 4. Diabetic secondary complications were ameliorated in some recipients, and quality of life studies showed significant gains after the transplant in all recipient categories. CONCLUSIONS Patient and graft survival rates have significantly improved over time as surgical techniques and immunosuppressive protocols have evolved. Eventually, islet transplants will replace pancreas transplants for suitable candidates, but currently pancreas transplants can be applied and should be an option at all stages of diabetes. Early transplants are preferable for labile diabetes, but even patients with advanced complications can benefit.

Abstract
OBJECTIVE To test the hypothesis that pancreas transplantation using the more physiologic method of portal venous-enteric (PE) drainage could be performed without compromising patient and graft outcome, compared with the standard method of systemic venous-bladder (SB) drainage. METHODS Between November 1995 and November 1998, the authors prospectively followed up 20 consecutive patients with SB drainage followed by 20 consecutive patients with PE drainage. All patients underwent simultaneous pancreas-kidney transplantation, and all were immunosuppressed with antilymphocyte serum, cyclosporin, azathioprine, and steroids. RESULTS The actuarial patient survival rate at 1 year was 95% in the SB group and 100% in the PE group. Death-censored kidney graft survival was 100% in both groups; pancreas graft survival was 95% in the SB group and 100% in the PE group. The mean initial hospital stay was 15 days for both groups. However, during the first 6 months after transplantation, the SB group required more medical day-unit visits, mostly for treatment of metabolic acidosis and dehydration. The incidence of urinary tract infections was similar in both groups. The incidence of cytomegalovirus infections was significantly less in the PE group. The incidence of acute rejection was 37% in the SB group and 15% in the PE group. Mean serum creatinine levels 6 months after transplantation were significantly lower in the PE group than in the SB group. Glycemic control was excellent in both groups, but fasting serum insulin levels were significantly lower in the PE group. CONCLUSIONS The PE method of pancreas transplantation can be performed with excellent patient and graft outcomes.

Abstract
BACKGROUND Bladder drainage is the most common technique for managing the exocrine secretions of pancreaticoduodenal grafts. However, bladder drainage can cause urinary, pancreatic, and metabolic complications that may require conversion to enteric drainage. With enteric drainage, urinary amylase levels cannot be monitored as a marker for rejection. After enteric conversion, rejection is the major cause of graft loss. Timing the conversion to reduce immunologic graft loss would greatly improve patient and graft survival rates. Our study was designed to assess the incidence of, indications for, and complications of converting from bladder to enteric drainage after pancreaticoduodenal transplantations. METHODS We retrospectively reviewed our experience with 80 recipients who underwent enteric conversion. We studied the recipient category, the interval from transplantation to conversion, the interval from the last rejection episode to conversion, the indications for conversion, the type of enteric drainage at conversion (loop versus Roux-en-Y), the results of the conversion, and postconversion complications. RESULTS The major indications for conversion were metabolic acidosis (n = 26, 33%), recurrent urinary tract infections (UTIs) (n = 16, 20%), reflux pancreatitis (n = 15, 19%), and hematuria (n = 12, 15%). For most recipients, their symptoms resolved after conversion (n = 76, 95%). The cumulative probability of undergoing conversion was 13% at 12 months, 21% at 36 months, and 25% at 60 months. Of the recipients with surgical complications after conversion (n = 12, 15%), one lost his graft as a result of pancreatitis. Overall, of the 80 recipients who underwent conversion, 12 (15%) lost their graft, most due to rejection (n = 8, 75%). Immunologic graft loss was highest for recipients of pancreas transplants alone who underwent conversion < or = 6 months after transplantation or < or = 1 year after their last rejection episode. CONCLUSIONS Enteric conversion is safe and therapeutic in recipients with complications related to the exocrine secretions of bladder-drained pancreas grafts. After conversion, rejection accounted for 75% of the grafts lost. However, waiting at least 1 year after the last rejection episode significantly reduced immunologic graft loss.

Abstract
OBJECTIVE To evaluate the incidence and management of the urological complications after bladder-drained pancreatic transplantation. PATIENTS AND METHODS A retrospective study was carried out on 24 consecutive bladder-drained pancreatic transplants in 24 patients with type I insulin-dependent diabetes mellitus, 22 with simultaneous kidney transplants and two of pancreas alone, over a period of 53 months. RESULTS All 24 patients were alive within a mean follow-up of 26.7 months: 22 patients have functioning pancreatic grafts and are insulin-independent. The overall incidence of urological complications was 83% (20 of 24 patients) and 14 patients had more than one complication. The major non-infective complication was haematuria (eleven), which was treated conservatively, with only two patients requiring enteric conversion. One patient developed a duodeno-vesical fistula and lost the functioning pancreatic graft as a consequence. Other non-infective complications were urethritis (one) and urethral stricture (one), which were managed with catheter drainage and internal urethrotomy, respectively, and vulval ulcers (one) and reflux pancreatitis (one) treated conservatively. The main infective complications were recurrent lower urinary tract infection (nine), asymptomatic persistent bacteriuria (nine), prostatitis and epididymitis (one), and pyelonephritis (one), all managed with appropriate antibiotics. Three patients developed septicaemia from urosepsis and were treated successfully with antibiotics. Two patients developed genital warts and were treated with laser vaporization. CONCLUSION Although bladder drainage has significantly contributed to the increasing success of pancreatic transplantation, urological complications are frequent and can be serious and life-threatening. As more of these procedures are performed urologists need to be able to recognize and treat these problems.

Abstract
Impaired salivary function with resultant severe dryness of the mouth, or xerostomia, may occur in association with a variety of systemic disorders or therapies. No adequate treatment exists for this debilitating condition, which impedes normal oral function, in particular alimentation and phonation. This study explores the feasibility of salivary gland autotransplantation, using a canine model. A salivary gland with its duct and surrounding blood vessels still attached was excised and reimplanted in the dog's thigh by anastomosing the graft's blood vessels to the femoral artery and vein. The duct was sutured to an artificial orifice cut in the thigh's skin, from which the saliva was collected. Salivary secretion was induced by a single intravenous bolus of pilocarpine (5 mg). Preoperative (normal) salivation was measured by collecting saliva from the gland in situ. Periodic functional studies showed normal saliva production during the first month after grafting, after which the salivary flow was reduced by 35% over the next 2 months. This reduction was interpreted as a sign of disuse atrophy resulting from the lack of autonomic innervation. To overcome this impediment, oral pilocarpine (5 mg/day) was administered to the recipient dog, after which normal levels of saliva were excreted through the graft during the 3-month follow-up period. The quality of the graft saliva was assessed by its protein and electrolyte levels, which showed close to normal values.

Abstract
BACKGROUND Tissue samples for the diagnosis of pancreatic allograft rejection are now obtained routinely through the application of the percutaneous needle biopsy technique. The availability of biopsy material (89% adequate for diagnosis in our setting) presents a challenge for pathologists who are asked to provide a fast and accurate diagnosis of rejection and its severity, while at the same time being able to differentiate rejection from other causes of graft dysfunction. METHODS To differentiate rejection from other pathologic processes, 26 histologic features were assessed in 92 biopsies performed for confirmation of clinical diagnosis of rejection and the results were compared with 31 protocol biopsies, 12 allograft pancreatectomies with non-rejection pathology, and 30 native pancreas resections with various disease processes. RESULTS Based on these comparisons, a constellation of findings relating to the vascular, septal, and acinar inflammation was identified for the diagnosis of rejection. Application of these features led us to revise our scheme for grading rejection (ranging from 0-normal to V-severe rejection) to include the categories of "inflammation of undetermined significance" and "minimal rejection." The scheme was used by five pathologist to grade 20 biopsies independently of any clinical data and the interobserver level of agreement was highly significant (kappa=0.83, P<0.0001). This grading scheme was applied blindly to all (183) biopsies from 77 patients with 6-52 months of follow-up. The correlation of the highest degree of rejection on each patient and ultimate graft loss (0% for grades 0-I, 11.5% for grade II, 17.3% for grade III, 37.5% for grade IV, and 100% for grade V) was highly statistically significant (P<0.002). The fraction of grafts lost due to pure immunologic causes increased proportionally to the grade of rejection (0, 50, 66, and 100% for grades II, III, IV, and V, respectively). CONCLUSIONS This study provides strong support for the proposed pancreas rejection grading scheme and confirms its potential for practical use.

Abstract
PURPOSE Pancreas transplantation is increasingly being used in the treatment of type I insulin-dependent diabetes mellitus. Because bladder drainage of the exocrine pancreatic secretion is the procedure of choice, urological complications are frequent. As the number of these procedures increases the urologist will have an extended role in the management of the postoperative complications, the majority of which are urological. MATERIALS AND METHODS The literature from 1985 on the complications related to pancreas transplants was reviewed. RESULTS Approximately 50 to 60% of bladder drained pancreas transplant recipients will have a urological complication postoperatively. CONCLUSIONS The increasing application of bladder drained pancreas transplantation in the treatment of type I insulin-dependent diabetes mellitus necessitates that the clinical urologist is familiar with the management of complications related to this procedure.

Abstract
The clinical success of pancreas transplantation is limited by the difficulty in diagnosing rejection. In simultaneous pancreas kidney (SPK) transplantation, the diagnosis of pancreatic rejection is particularly difficult in the absence of clinical evidence of kidney rejection. Moreover, patients receiving only pancreas grafts will not have a concomitantly grafted kidney to serve as a "sentinel" for rejection. Percutaneous pancreas graft biopsy has been reported in a few small series but has not been adopted for broad clinical use. We describe the evaluation of 69 consecutive episodes of suspected isolated pancreas allograft rejection by percutaneous pancreas allograft biopsy. These rejection episodes occurred in 41 patients with bladder-drained pancreas transplants (25 SPK, 14 pancrease after kidney transplants [PAK], amd two pancreas transplant alone [PTA]). The indications for percutaneous pancreas biopsy were a twofold or greater increase in serum amylase or lipase, or a sustained 40% to 50% drop in urine amylase in the setting of no evidence of renal allograft dysfunction in SPK transplants. Biopsies were performed with color-flow Doppler ultrasound localization using an 18-gauge automated biopsy needle. Pancreatic tissue adequate for histologic evaluation was obtained in 61 of 69 cases (88%). There were two cases of intraabdominal bleeding, one of which required surgical intervention; the other resolved spontaneously. Histologic assessment of the biopsies demonstrated varying degrees of acute cellular rejection in 48 of 61 specimens (79%). Twelve specimens (20%) were free of histologic evidence of rejection, and one specimen (2%) showed acute pancreatitis. At the time of suspected rejection mean serum amylase and lipase values were increased 3.6 and 8.3-fold, respectively, and urine amylase was decreased by a mean of 45%. We conclude that the commonly used markers for pancreas allograft rejection are only about 80% specific for acute rejection. Percutaneous pancreas allograft biopsy is safe and allows the avoidance of unnecessary antirejection therapy with its attendant side effects and cost.

Abstract
BACKGROUND Urinary amylase (UA) remains the most common biochemical parameter to detect rejection in bladder-drained pancreas allografts. With the development of the cystoscopic transduodenal pancreas transplant biopsy technique, tissue samples of the pancreas graft are now frequently obtained. A definitive correlative analysis between UA activity and biopsy results has not been done in the three different pancreas transplant categories (simultaneous pancreas-kidney, pancreas transplant alone, and pancreas after kidney). METHODS We studied 66 pancreaticoduodenal biopsy specimens obtained for hypoamylasuria. Rejection was defined as a greater than 25% decrease from stable posttransplantation baseline on two consecutive measurements at least 12 hours apart. To perform biopsies we used our newly developed 14- and 16-gauge core-cut needles (50 cm long). Biopsy specimens were considered positive if either pancreatic or duodenal rejection was found. To assess the quality of UA activity we studied 13 biopsy specimens from patients with stable UA levels; these 13 specimens were negative for rejection. RESULTS Acute rejection was diagnosed in 36 biopsy specimens (55%). The mean decrease in UA levels was 67% +/- 8% (range, 28% to 99%) for the positive biopsy results, and 57% +/- 16% (range, 22% to 92%) for the negative biopsy results (p = 0.147). Within 1 month, UA levels returned to baseline in 19% of our patients with positive biopsy results versus 97% with negative results; postbiopsy 1-year graft survival was 64% versus 97% (p < or = 0.05). In assessing the test quality of our biopsy specimens (including 13 obtained for reasons other than hypoamylasuria), we found a sensitivity of 100% (stable UA levels mean no rejection) and a specificity of 30%. The predictive value of a positive test was 53%; of a negative test it was 100%. By performing biopsies we avoided antirejection treatment in 47% of the patients studied. We found no biopsy-related complications. CONCLUSIONS Stable UA levels reliably rule out rejection; a decrease is a marker for acute rejection but is unspecific. Performing biopsy is currently the only way to reliably diagnose rejection in solitary pancreas recipients (pancreas transplant alone and pancreas after kidney) and in simultaneous pancreas-kidney recipients with isolated hypoamylasuria. The procedure is safe and should always be attempted to avoid unnecessary rejection treatment.

Abstract
The use of allograft biopsies to guide treatment after solid organ transplantation is a valuable tool in the detection and treatment of rejection. Prior development and use of the cystoscopically guided pancreatic allograft biopsy have allowed for more accurate and timely diagnosis of pancreatic allograft dysfunction, possibly contributing to our 1-year pancreas graft, renal allograft and patient survival rates of 87.1%, 88.5% and 96.8%, respectively. We reviewed our experience, examining efficacy and complication rates of pancreas and kidney biopsies in 31 cadaveric pancreas or combined kidney and pancreas transplants performed between June 1990 and February 1992 with at least 1 year of followup. There were 94 pancreas, 54 kidney and 53 duodenal mucosal biopsies in 29 evaluable patients. This biopsy technique uses a 24.5F side-viewing nephroscope to view the cystoduodenostomy, with the duodenum acting as a portal for biopsy needles into the pancreas. Pancreatic tissue is obtained with either an 18 gauge, 500 mm. Menghini aspiration/core needle or an 18 gauge, 500 mm. Roth core needle. Percutaneous renal allograft biopsies are performed independently or simultaneously with the pancreas biopsies using a 16 gauge spring loaded needle. Pancreas biopsies were prompted by clinical indications of rejection (decreased urinary amylase, increased serum amylase or increased serum creatinine) or by protocol (10, 21 and 40 days postoperatively). Among the biopsies 30% were required by protocol, of which 10 (36%) revealed abnormal pathological findings and 5 (18%) showed evidence of occult cellular rejection. Renal biopsies demonstrated rejection in 69% of the cases. Of simultaneous pancreas/kidney biopsies 33% revealed concomitant rejection. A total of 88 Menghini needles with 170 passes was used in 73 biopsy attempts, yielding 126 tissue cores with a 16% complication rate. A total of 41 Roth needles was used with 73 passes in 34 biopsy attempts, yielding 55 tissue cores with a complication rate of 21%. Complications included self-limited bleeding from the biopsy site in 13% of the cases, bleeding requiring clot evacuation and fulguration in 1% and asymptomatic hyperamylasemia in 12%. Renal biopsy complications included 1 arteriovenous fistula (2%). We conclude that ultrasound and cystoscopically guided pancreatic allograft biopsy and percutaneous renal allograft biopsies are safe and essential methods of obtaining tissue for histological diagnosis without serious sequelae. The Menghini and Roth needles in cystoscopically guided pancreatic allograft biopsy have similar yield and complication rates in obtaining pancreatic tissue, although they require different performance techniques. In some cases both needles are necessary and are complementary in obtaining adequate tissue.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Simultaneous pancreas-kidney transplantation is a therapeutic option for type I diabetics with end-stage renal disease. It aims to correct the uremic state, to normalize glucose hemeostasis, and to ameliorate diabetic complications. Careful donor-recipient selection and meticulous intra-operative and postoperative care will substantially impact recipient morbidity. An understanding of the technical aspects of the surgical procedure and its metabolic and immunological consequences is necessary to successfully manage a pancreas-kidney transplant recipient, many of whom are nursed in intensive care units. A successful outcome is predicted in early recognition of technical complications and aggressive management of rejection to achieve the current 1-year graft survival rates of 75% for pancreas transplants and 84% for kidney transplants.
