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
Simultaneous pancreas-kidney (SPK) transplantation remains the most effective treatment for providing consistent and long-term euglycemia in patients having type 1 diabetes with renal failure. Thrombosis of the pancreatic vasculature continues to contribute significantly to early graft failure and loss. We compared the rate of thrombosis to graft loss and systematically reviewed risk factors impacting early thrombosis of the pancreas allograft following SPK transplantation. We searched the MEDLINE, EMBASE, The Cochrane Library, and PREMEDLINE databases for studies reporting thrombosis following pancreas transplantation. Identified publications were screened for inclusion and synthesized into a data extraction sheet. Sixty-three studies satisfied eligibility criteria: 39 cohort studies, 22 conference abstracts, and 2 meta-analyses. Newcastle-Ottawa Scale appraisal of included studies demonstrated cohort studies of low bias risk; 1127 thrombi were identified in 15 936 deceased donor, whole pancreas transplants, conferring a 7.07% overall thrombosis rate. Thrombosis resulted in pancreatic allograft loss in 83.3% of reported cases. This review has established significant associations between donor and recipient characteristics, procurement and preservation methodology, transplantation technique, postoperative management, and increased risk of early thrombosis in the pancreas allograft. Further studies examining the type of organ preservation fluid, prophylactic heparin protocol, and exocrine drainage method and early thrombosis should also be performed.

Abstract
The aim of this minireview is to compare various pancreas transplantation exocrine drainage techniques i.e., bladder vs enteric. Both techniques have different difficulties and complications. Numerous comparisons have been made in the literature between exocrine drainage techniques throughout the history of pancreas transplantation, detailing complications and their impact on graft and patient survival. Specific emphasis has been made on the early postoperative management of these complications and the related surgical infections and their consequences. In light of the results, a number of bladder-drained pancreas grafts required conversion to enteric drainage. As a result of technical improvements, outcomes of the varied enteric exocrine drainage techniques (duodenojejunostomy, duodenoduodenostomy or gastric drainage) have also been discussed i.e., assessing specific risks vs benefits. Pancreatic exocrine secretions can be drained to the urinary or intestinal tracts. Until the late 1990s the bladder drainage technique was used in the majority of transplant centers due to ease of monitoring urine amylase and lipase levels for evaluation of possible rejection. Moreover, bladder drainage was associated at that time with fewer surgical complications, which in contrast to enteric drainage, could be managed with conservative therapies. Nowadays, the most commonly used technique for proper driving of exocrine pancreatic secretions is enteric drainage due to the high rate of urological and metabolic complications associated with bladder drainage. Of note, 10% to 40% of bladder-drained pancreata eventually required enteric conversion at no detriment to overall graft survival. Various surgical techniques were originally described using the small bowel for enteric anastomosis with Roux-en-Y loop or a direct side-to-side anastomosis. Despite the improvements in surgery, enteric drainage complication rates ranging from 2%-20% have been reported. Treatment depends on the presence of any associated complications and the condition of the patient. Intra-abdominal infection represents a potentially very serious problem. Up to 30% of deep wound infections are associated with an anastomotic leak. They can lead not only to high rates of graft loss, but also to substantial mortality. New modifications of established techniques are being developed, such as gastric or duodenal exocrine drainage. Duodenoduodenostomy is an interesting option, in which the pancreas is placed behind the right colon and is oriented cephalad. The main concern of this technique is the challenge of repairing the native duodenum when allograft pancreatectomy is necessary. Identification and prevention of technical failure remains the main objective for pancreas transplantation surgeons. In conclusion, despite numerous techniques to minimize exocrine pancreatic drainage complications e.g., leakage and infection, no universal technique has been standardized. A prospective study/registry analysis may resolve this.

Abstract
BACKGROUND Pancreatic pseudocysts are rarely reported complications of pancreas transplant. CASE We present a case of a patient with simultaneous pancreas and kidney transplant with bladder exocrine drainage who developed reflux pancreatitis and symptomatic pancreatic pseudocyst as a result of neuropathic bladder, 15 years after the original transplant. He was initially managed with percutaneous aspiration and drainage along with Foley catheter placement to help with bladder emptying. But the pseudocyst recurred after drains and Foley were removed. Eventually, he underwent an enteric conversion of the pancreas allograft with resolution of his symptoms and the pseudocyst. CONCLUSIONS Enteric conversion should be considered in cases of bladder-drained pancreas transplants with recurrent reflux pancreatitis and/or pseudocyst formation.

Abstract
Solid organ transplantation (SOT) has emerged from an experimental approach in the 20th century to now being an established and practical definitive treatment option for patients with end-organ dysfunction. The evolution of SOT has seen the field progress rapidly over the past few decades with incorporation of a variety of solid organs-liver, kidney, pancreas, heart, and lung-into the donor pool. New advancements in surgical technique have allowed for more efficient and refined multi-organ procurements with minimal complications and decreased ischemic injury events. Additionally, immunosuppression therapy has also seen advancements with the expansion of immunosuppressive protocols to dampen the host immune response and improve short and long-term graft survival. However, the field of SOT faces new barriers, most importantly the expanding demand for SOT that is outpacing the current supply. Allocation protocols have been developed in an attempt to address these concerns. Other avenues for SOT are also being explored to increase the donor pool, including split-liver donor transplants, islet cell implantation for pancreas transplants, and xenotransplantation. The future of SOT is bright with exciting new research being explored to overcome current obstacles.

Abstract
Background Although bladder drainage is effective for monitoring urine amylase levels to detect graft rejection, enteric drainage is performed more frequently. The optimal method for monitoring pancreatic enzyme secretions remains unclear. We investigated graft survival in recipients of bladder drainage and assessed the risk of graft rejection and failure after enteric conversion. Material/Methods From January 1999 to October 2015, we performed 318 pancreas transplantations at our institution. We enrolled 180 recipients who underwent pancreas transplantation with bladder drainage (82 underwent enteric conversion and the rest did not). Results The mean interval between pancreas transplantation and enteric conversion was 20±24 months. The graft survival rate was significantly higher in the enteric conversion group for 10 years after pancreas transplantation than in the maintain bladder drainage group. After enteric conversion, 14 recipients lost graft function. The interval between enteric conversion and graft failure was 43±26 months. In the enteric conversion group, immediate postoperative thromboembolectomy (HR=12.729, p=0.000), renal failure (HR=5.710, p=0.005), pancreas graft rejection after EC (HR=19.006, p=0.000), and delayed graft function (HR=7.021, p=0.001) had a significant relationship with graft failure. Conclusions Enteric conversion can be safe and effective for improving short- and long-term graft survival if performed after approximately 9 months. Caution should be exercised with enteric conversion if recipients have a history of thromboembolectomy, delayed graft function, or renal failure.

Abstract
PURPOSE OF REVIEW The surgical techniques of pancreas transplantation have been evolving and significantly improved over time. This article discusses different current techniques and their modifications. RECENT FINDING At this time, the most commonly used technique is systemic venous drainage (for venous outflow) and enteric drainage (for management of exocrine pancreatic secretions). However, new modifications of established techniques such as gastric or duodenal exocrine drainage and venous drainage to the inferior vena cava continue to be introduced. SUMMARY This article provides a state-of the-art review of the most prevalent up-to-date surgical techniques as well as a synopsis of their specific risks and benefits. The article also provides the most current registry data regarding utilization of different surgical techniques in the United State and worldwide.

Abstract
Vascularized pancreas transplantation is the only treatment that establishes normal glucose levels and normalizes glycosylated hemoglobin levels in type 1 diabetic patients. The first vascularized pancreas transplant was performed by William Kelly and Richard Lillehei, to treat a type 1 diabetes patient, in December 1966. In Brazil, Edison Teixeira performed the first isolated segmental pancreas transplant in 1968. Until the 1980s, pancreas transplants were restricted to a few centers of the United States and Europe. The introduction of tacrolimus and mycophenolate mofetil in 1994, led to a significant outcome improvement and consequently, an increase in pancreas transplants in several countries. According to the International Pancreas Transplant Registry, until December 31st, 2010, more than 35 thousand pancreas transplants had been performed. The one-year survival of patients and pancreatic grafts exceeds 95 and 83%, respectively. The better survival of pancreatic (86%) and renal (93%) grafts in the first year after transplantation is in the simultaneous pancreas-kidney transplant group of patients. Immunological loss in the first year after transplant for simultaneous pancreas-kidney, pancreas after kidney, and pancreas alone are 1.8, 3.7, and 6%, respectively. Pancreas transplant has 10 to 20% surgical complications requiring laparotomy. Besides enhancing quality of life, pancreatic transplant increases survival of uremic diabetic patient as compared to uremic diabetic patients on dialysis or with kidney transplantation alone.

Bladder vs enteric drainage following pancreatic transplantation: How best to support graft survival? A best evidence topic. Int J Surg 2015; 22:149-52.

Abstract
A best evidence topic in transplant surgery was written according to a structured protocol. The question addressed was: In patients undergoing pancreatic transplantation alone, does enteric drainage or bladder drainage of exocrine secretions provide the best graft survival? A total of 155 papers were identified using the search protocol described, of which four retrospective cohort studies represented the best evidence available to answer the clinical question. The authors, journal, date and country of publication, study type, patient group studied, relevant outcomes and results of these papers are tabulated. Three of the four studies demonstrated no significant difference in graft survival between enteric drainage and bladder drainage at 6 months or 1 year. This included the largest and most recent study which showed that patient survival, graft survival and technical failure rates at 1 year were equal between the two duct management techniques. However, one study indicated lower graft survival at 1 year with enteric drainage due to a higher technical failure rate. Therefore, the clinical bottom line is that there is no significant difference in graft survival between enteric drainage or bladder drainage of pancreatic exocrine secretions for pancreas transplants alone. There is some evidence that enteric drainage may be associated with higher technical failure and higher graft rejection but this has not been universally demonstrated. Given the historical nature of all the available evidence, further appropriately powered and randomised Level 1 studies are necessary to clarify this important issue.

Abstract
BACKGROUND Type 1 diabetes mellitus is a chronic condition often leading to disabling complications including retinopathy, neuropathy and cardiovascular disease which can be modified by intensive treatment with insulin. Such treatment, however, is associated with a restrictive lifestyle and risk of hypoglycaemic morbidity and mortality. METHODS This review examines the role of pancreas transplantation in patients with Type 1 diabetes mellitus. RESULTS Pancreas transplantation is currently the only proven option to achieve long-term insulin independence, resulting in an improvement or stabilization of those diabetic related complications. The hazards of pancreas transplantation as a major operation are well known. Balancing the risks of a surgical procedure, with the benefits of restoring normoglycaemia remains an important task for the pancreas transplant surgeon. Pancreas transplantation is not an emergency operation to treat poorly managed and non-compliant patients with debilitating complications. It is a highly specialized procedure which has evolved both in terms of the surgical technique, patient selection and assessment. CONCLUSION Pancreas transplantation has emerged as the single most effective way to achieve normal glucose homeostasis in patients with Type 1 diabetes mellitus.

Abstract
ABSTRACT Pancreas transplantation is the only treatment able to reestablish normal glucose and glycated hemoglobin levels in insulin-dependent diabetic patients without the use of exogenous insulin. The evolution of pancreas transplantation in treatment of diabetes was determined by advances in the fields of surgical technique, organ preservation and immunosuppressants. The main complication leading to graft loss is technical failure followed by acute or chronic rejection. Technical failure means graft loss within the first three months following transplantation due to vascular thrombosis (50%), pancreatitis (20%), infection (18%), fistula (6.5%) and bleeding (2.4%). Immunological complications still affect 30% of patients, and rejection is the cause of graft loss in 10% of cases. Chronic rejection is the most common late complication. Cardiovascular diseases are the most common causes of late mortality in pancreas transplantation, so it remains the most effective treatment for type 1 diabetes patients. There is a significant improvement in quality of life and in patient's survival rates. The development of islet transplantation could eliminate or minimize surgical complications and immunosuppression.

Abstract
INTRODUCTION Management of the exocrine drainage of the pancreatic graft in simultaneous pancreas kidney (SPK) transplantation has been a matter of debate for years. There is currently a trend toward a more physiological enteric drainage (ED). This study compared short- and long-term complications and graft survival in patients with enteric versus bladder exocrine secretion drainage. PATIENTS AND METHODS Between January 1995 and November 2005, we performed 75 SPK transplants: 55 with ED and 20 with bladder drainage (BD). The rates of complications and graft survival were monitored over at least 36 months after transplantation. RESULTS Mean posttransplant follow-up was 119.5 +/- 6.6 months. Urinary infection, hematuria, reflux pancreatitis, and repeat surgery rates were all significantly higher among the BD area. There was no intergroup difference in rejection rates or in the incidence of graft thrombosis, transplantectomy, anastomotic dehiscence, or intra-abdominal abscesses. Pancreas and kidney graft survival rates were similar in the two groups. CONCLUSIONS In our experience, ED was more physiological than BD, and was associated with fewer complications.

Abstract
BACKGROUND The clinical and pathological findings of enteric-drained (ED) versus bladder-drained (BD) pancreas transplantation are still controversial. In this study, we compared early outcome and histological findings of these 2 methods. METHODS In an experimental animal model, after diabetization, 16 dogs were randomly divided into 2 groups. In the first group, the pancreas was transplanted with enteric drainage, and in the second group, with bladder drainage. We evaluated early clinical and pathological outcomes. RESULTS The mean survival time was 11.25 +/- 5.0 (range, 5-20) days for group 1 and 13.6 +/- 7.2 (range, 3-23) days for group 2 (P>.05). Fasting blood sugar values (FBS) before transplantation were 279 +/- 26.8 mg/dL versus 278 +/- 41.6 mg/dL, respectively (P>.05). Two weeks postoperative serum FBS had decreased to 84.9 +/- 2.9 versus 84.2 +/- 0.98, respectively (P>.05). Serum amylase in the BD and ED groups were 378.5 +/- 328 versus 422.6 +/- 54.7 mg/dL, respectively (P>.05). Early leakage was not observed in dogs with BD, whereas it was 37.5% among dogs with ED (P<.05). Clinical and pathological evidences of pancreatic necrosis occurred in 37.5% of dogs with BD versus 62.5% of dogs with ED (P>.05). DISCUSSION Although the early outcomes of these drainage methods (ED vs BD) were statistically similar more dogs with ED experienced early complications than with BD.

Abstract
The prompt diagnosis and management of acute surgical conditions in immunocompromised solid organ transplant recipients are of critical importance. These conditions may or may not be related or to the transplanted allograft(s). This is a case report of a 41-year-old woman who received a simultaneous pancreas-kidney transplant. Nine years after the transplant, she developed acute appendicitis with a periappendiceal abscess and a fecalith, and she was treated with percutaneous drainage of the abscess and eventual semielective appendectomy. This is the first known report of acute appendicitis in a pancreas allograft recipient in the English literature.

Abstract
BACKGROUND Pancreas transplantation is nowadays the only treatment to reestablish normal blood glucose in diabetic patients. Moreover, transplantation may also prevent and possibly even revert diabetes-related complications. We present our results with the first 4 years of a pancreas transplantation program. MATERIALS AND METHODS From February 2000 to June 2004, we performed 43 pancreas transplants in 42 recipients. In all cases the technique was enteric drainage of the exocrine secretions and systemic venous derivation to the inferior vena cava for endocrine secretions. RESULTS A simultaneous pancreas-kidney transplant was performed in 37 (88.1%) patients, a pancreas after kidney in 4 (9.5%) patients, and a retransplant in 1 (2.4%) patient. Glycosylated hemoglobin and C peptide returned to normal values in all cases. Patient and graft survivals were 91% and 84%, respectively, after a median follow-up of 19 months. The rate of reoperations was 31% with an overall 16% graft loss. CONCLUSIONS Our results were comparable to those of larger series.

Abstract
BACKGROUND Although there is a tendency to perform enteric drainage of pancreas transplants in simultaneous pancreas-kidney (SPK) transplantation, bladder drainage is still preferable in pancreas transplantation alone (PTA) or after a previous kidney transplantation (PAK). Our hypothesis was that enteric conversion of a bladder drained pancreas is an effective and safe procedure. We studied the complication rate and physiological effects of enteric conversion in patients with primary bladder-drained SPK transplantation. PATIENTS We performed 51 enteric conversions in bladder-drained SPK transplant recipients. As we observed a low complication rate, with time enteric conversions were also performed for less strict and severe indications. RESULTS The main indications for conversion were urological problems, metabolic complications and reflux-pancreatitis. The median transplantation-conversion interval was 12 months (range 2-40 months). Post-operative complications consisted of seven urinary tract infections, two low-grade superficial wound infections, one minor bleeding, one phlebitis and one paralytic ileus. In two patients, a relaparotomy was necessary. No graft rejection following enteric conversion was found. Long-term renal and pancreatic function were not affected by the enteric conversion. Three-year patient, kidney and pancreas survival rates after enteric conversion were 93, 97 and 93%, respectively (censored data). CONCLUSION Enteric conversion after pancreas transplantation is an effective and safe procedure. Therefore, we suggest a policy of a two-step approach of primary bladder drainage followed by an enteric conversion of the pancreas in a selected group of SPK patients.

Abstract
INTRODUCTION Pancreatic transplantation is currently the only therapeutic alternative able to restore normal blood glucose levels in diabetic patients. Moreover, this procedure can halt or even reverse diabetes-related complications. The aim of this study was to present our experience and the results of the first 4 years of a pancreatic transplantation program in our center. MATERIAL AND METHOD From February 2000 to June 2004, 43 pancreatic transplantations were performed in 42 recipients in the Carlos Haya Regional Hospital in Malaga (Spain). In all patients, the technique of enteric drainage of exocrine pancreatic secretions and systemic venous shunting of endocrine secretions (to the inferior vena cava) was used. RESULTS There were 37 (88.1%) simultaneous pancreas-kidney transplantations, 4 (9.5%) in patients with prior kidney transplantation and 1 retransplantation (2.4%). In all patients, glycosylated hemoglobin and C-peptide levels returned to normal. Patient and pancreatic graft survival were 91% and 84%, respectively, with a median follow-up of 19 months. The reintervation rate was 31%, with an overall rate of graft loss of 16%. CONCLUSIONS The results obtained in our series are similar to those reported for large series.

Abstract
BACKGROUND Anastomotic leaks after pancreas transplants usually occur early in the postoperative course, but may also be seen late post-transplant. We studied such leaks to determine predisposing factors, methods of management, and outcomes. RESULTS Between January 1, 1994 and December 31, 2002, a total of 25 pancreas transplant recipients at our institution experienced a late leak (defined as one occurring more than 3 months post-transplant). We excluded recipients with an early leak or with a leak seen immediately after an enteric conversion. The mean recipient age was 40.3 yr; mean donor age, 31.3 yr. The category of transplant was as follows: simultaneous pancreas-kidney (n = 5, 20%), pancreas after kidney (n = 10, 40%), and pancreas transplant alone (n = 10, 40%). At the time of their leak, most recipients (n = 23, 92%) had bladder-drained pancreas grafts; only two recipients (8%) had enteric-drained grafts. The mean time from transplant to the late leak was 20.5 months (range = 3.5-74 months). A direct predisposing event or risk factor occurring in the 6 wk preceding leak diagnosis was identified in 10 (40%) of the recipients. Such events or risk factors included a biopsy-proven episode of acute rejection (n = 4, 16%), a history of blunt abdominal trauma (n = 3, 12%), a recent episode of cytomegalovirus infection (n = 2, 8%), and obstructive uropathy from acute prostatitis (n = 1, 4%). Non-operative or conservative care (Foley catheter placement with or without percutaneous abdominal drains) was the initial treatment in 14 (56%) of the recipients. Such care was successful in nine (64%) of the 14 recipients; the other five (36%) required surgical repair after failure of conservative care at a mean of 10 d after Foley catheter placement. Of the 25 recipients, 11 underwent surgery as their initial leak treatment: repair in nine and pancreatectomy because of severe peritonitis in two. After appropriate management (conservative or operative) of the initial leak, five (20%) of the 25 recipients had a recurrent leak; the mean length of time from initial leak to recurrent leak was 5.6 months. All five recipients with a recurrent leak ultimately required surgery. CONCLUSIONS Late anastomotic leaks are not uncommon; they may be more common with bladder-drained grafts. One-third of the recipients with a late leak had experienced some obvious preceding event that predisposed to the leak. For two-thirds of our stable recipients with bladder-drained grafts, non-operative treatment of the leak was successful.
