Abstract
Background Total pancreatectomy and islet autotransplantation (TPIAT) is a recognised treatment for chronic pancreatitis (CP) with the potential to mitigate or prevent pancreatogenic diabetes. We present our 10-year follow-up of TPIAT patients. Methods The University Hospitals of Leicester performed 60 TPIAT procedures from September 1994 to May 2011. Seventeen patients completed their 10-year assessment and were grouped using the modified Auto-Igls criteria; good response, n=5 (insulin-independent for first 5 years post-TPIAT); partial response, n=6 (insulin requirements <20 iU/day post-TPIAT) and poor response, n=6 (insulin requirements ≥20 iU/day post-TPIAT). C-peptide, haemoglobin A1c (HbA1c) and oral glucose tolerance test (OGTT) were undertaken preoperatively (baseline), then at 3, 6 months and then yearly for 10 years. Data was analysed using analysis of variance (ANOVA). Results Median C-peptide levels were significantly higher, 120 minutes following OGTT, in the "good response" compared to "partial" and "poor" groups (two-way ANOVA test, P<0.0001). All groups demonstrated preservation of C-peptide release. HbA1c levels were significantly lower in the "good response" compared to "partial" and "poor" groups (two-way ANOVA test, P<0.0003 and P<0.0001). Median fasting glucose levels at 30 and 120 min following OGTT, were significantly lower in the "good response" compared to "partial" and "poor" groups (two-way ANOVA test, P<0.0001 and P<0.0001). Conclusions TPIAT preserves long-term islet graft functions in 10-year follow up. Even in patients in the poor response group, there is evidence of C-peptide release (>0.5 ng/mL) after OGTT stimulation potentially preventing long-term diabetes-related complications.

World J Transplant 2023; 13:10-24. [PMID: 36687559 PMCID: PMC9850868 DOI: 10.5500/wjt.v13.i1.10] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 11/24/2022] [Accepted: 12/23/2022] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Despite the increased use of total pancreatectomy with islet autotransplantation (TPIAT), systematic evidence of its outcomes remains limited.
AIM To evaluate the outcomes of TPIAT.
METHODS We searched PubMed, EMBASE, and Cochrane databases from inception through March 2019 for studies on TPIAT outcomes. Data were extracted and analyzed using comprehensive meta-analysis software. The random-effects model was used for all variables. Heterogeneity was assessed using the I2 measure and Cochrane Q-statistic. Publication bias was assessed using Egger’s test.
RESULTS Twenty-one studies published between 1980 and 2017 examining 1011 patients were included. Eighteen studies were of adults, while three studied pediatric populations. Narcotic independence was achieved in 53.5% [95% Confidence Interval (CI): 45-62, P < 0.05, I2 = 81%] of adults compared to 51.9% (95%CI: 17-85, P < 0.05, I2 = 84%) of children. Insulin-independence post-procedure was achieved in 31.8% (95%CI: 26-38, P < 0.05, I2 = 64%) of adults with considerable heterogeneity compared to 47.7% (95%CI: 20-77, P < 0.05, I2 = 82%) in children. Glycated hemoglobin (HbA1C) 12 mo post-surgery was reported in four studies with a pooled value of 6.76% (P = 0.27). Neither stratification by age of the studied population nor meta-regression analysis considering both the study publication date and the islet-cell-equivalent/kg weight explained the marked heterogeneity between studies.
CONCLUSION These results indicate acceptable success for TPIAT. Future studies should evaluate the discussed measures before and after surgery for comparison.

Abstract
The field of cell therapy of type 1 diabetes is a particularly interesting example in the scenario of regenerative medicine. In fact, β-cell replacement has its roots in the experience of islet transplantation, which began 40 years ago and is currently a rapidly accelerating field, with several ongoing clinical trials using β cells derived from stem cells. Type 1 diabetes is particularly suitable for cell therapy as it is a disease due to the deficiency of only one cell type, the insulin-producing β cell, and this endocrine cell does not need to be positioned inside the pancreas to perform its function. On the other hand, the presence of a double immunological barrier, the allogeneic one and the autoimmune one, makes the protection of β cells from rejection a major challenge. Until today, islet transplantation has taught us a lot, pioneering immunosuppressive therapies, graft encapsulation, tissue engineering, and test of different implant sites and has stimulated a great variety of studies on β-cell function. This review starts from islet transplantation, presenting its current indications and the latest published trials, to arrive at the prospects of stem cell therapy, presenting the latest innovations in the field.

Abstract
PURPOSE To evaluate the effect of intraoperative fluid type [half normal saline (0.45NS) or lactated Ringer's solution (LR)] on the risk of systemic inflammatory response syndrome (SIRS) and acute kidney injury after total pancreatectomy with islet autotransplantation in children. METHODS Retrospective review where demographics, operative details, systemic inflammatory response, and evaluation for end organ dysfunction over the first 5 postoperative days was obtained. Mixed effects Poisson regression compared risk of SIRS and acute kidney injury by intraoperative fluid type. RESULTS Forty three patients were included with no difference in demographic characteristics between groups. SIRS was observed in 95, 77, and 71% over post operative days 1, 3, and 5. Intraoperative fluid type was found to not be associated with postoperative SIRS (RR: 0.91, p = 0.23). However, female sex (RR: 1.30, p < 0.01), increased BMI (RR: 1.08, p < 0.01), and longer operative time (RR: 1.07, p < 0.01) were found to be factors that are associated with increased risk of postoperative SIRS. Intraoperative 0.45NS use was associated with increased acute kidney injury compared to LR on postoperative day 1 (52% vs 0%, p < 0.01), but not on postoperative days 3 or 5. CONCLUSION Intraoperative fluid type (0.45NS vs LR) does not increase the risk of postoperative SIRS in children after TPIAT. Predictive factors that are associated with an increased risk of eliciting postoperative SIRS includes female sex, increased BMI, and longer operative times. LEVEL OF EVIDENCE III.

Abstract
Total pancreatectomy (TP) is a procedure weighed down not only by postoperative morbidity and mortality but also by long-term effects as a consequence of endocrine and exocrine pancreatic insufficiency. While the latter is now managed quite effectively with pancreatic enzyme replacement therapy, the former remains a challenge. The diabetes resulting after TP, with the complete loss of endogenous insulin and contraregulatory hormones, is characterized by important glycemic variations and is, therefore, frequently referred to as "brittle diabetes". One method to reduce the impact of brittle diabetes in patients undergoing TP is the re-infusion of autologous pancreatic islets isolated from the resected pancreas. Indications to islet autotransplantation (IAT), originally described for patients undergoing TP for chronic pancreatitis, have since been extended to selected patients with other benign and malignant diseases of pancreas. This review recaps on the literature regarding long-term postoperative complications, their impact on quality of life after TP and the role of IAT.

Abstract
BACKGROUND Hyperglycemia and hypercholesterolemia are class effects of mammalian target of rapamycin inhibitors such as everolimus. This post hoc pooled analysis assessed the potential impact of these events on the efficacy of everolimus. METHODS Patients with advanced, low- or intermediate-grade pancreatic, gastrointestinal, or lung neuroendocrine tumors received either oral everolimus at 10 mg/d or a placebo in the RAD001 in Advanced Neuroendocrine Tumors 3 (RADIANT-3) and RAD001 in Advanced Neuroendocrine Tumors 4 (RADIANT-4) trials. A landmark progression-free survival (PFS) analysis by central review was performed for patients treated for at least 16 weeks (n = 308) and according to the occurrence of any-grade adverse events (AEs) within this treatment period. RESULTS The overall PFS with everolimus from the pooled analysis was 11.4 months (95% confidence interval, 11.01-13.93 months), which was consistent with the findings of RADIANT-3 and RADIANT-4. Overall, 19.1% and 9.8% of patients in RADIANT-3 and 11.9% and 6.4% of patients in RADIANT-4 developed any-grade hyperglycemia and hypercholesterolemia, respectively (regardless of the study drug). The duration of everolimus exposure was longer in patients who developed these AEs versus patients without these AEs. Overall, 308 patients were exposed to treatment for at least 16 weeks (hyperglycemia, 39 of 269 patients; hypercholesterolemia, 20 of 288 patients). No association was observed between the development of these AEs and PFS (18.8 and 14.1 months with and without hyperglycemia, respectively, and 14.1 and 14.8 months with and without hypercholesterolemia, respectively). CONCLUSIONS Although limitations apply because of the small number of AEs observed, there was no significant impact of these AEs on PFS; this suggests similar efficacy in the presence or absence of these events.

Abstract
Background The initial response to islet transplantation and the subsequent acute inflammation is responsible for significant attrition of islets following both autologous and allogenic procedures. This multicentre study compares this inflammatory response using cytokine profiles and complement activation. Methods Inflammatory cytokine and complement pathway activity were examined in two cohorts of patients undergoing total pancreatectomy followed either by autologous (n=11) or allogenic (n=6) islet transplantation. Two patients who underwent total pancreatectomy alone (n=2) served as controls. Results The peak of cytokine production occurred immediately following induction of anaesthesia and during surgery. There was found to be a greater elevation of the following cytokines: TNF-alpha (P<0.01), MCP-1 (P=0.0013), MIP-1α (P=0.001), MIP-1β (P=0.00020), IP-10 (P=0.001), IL-8 (P=0.004), IL-1α (P=0.001), IL-1ra (0.0018), IL-10 (P=0.001), GM-CSF (P=0.001), G-CSF (P=0.0198), and Eotaxin (P=0.01) in the allogenic group compared to autografts and controls. Complement activation and consumption was observed in all three pathways, and there were no significant differences in between the groups although following allogenic transplantation ∆IL-10 and ∆VEGF levels were significantly elevated those patients who became insulin-independent compared with those who were insulin-dependent. Conclusions The cytokine profiles following islet transplantation suggests a significantly greater acute inflammatory response following allogenic islet transplantation compared with auto-transplantation although a significant, non-specific inflammatory response occurs following both forms of islet transplantation.

Short- and long-term surgical outcomes of total pancreatectomy with islet autotransplantation: A comparative analysis of surgical technique and intraoperative heparin dosing to optimize outcomes. Pancreatology 2021; 21:291-298.

Abstract
BACKGROUND Total pancreatectomy with islet autotransplantation (TP-IAT) is an uncommon surgical procedure with unique perioperative management. We evaluated the short- and long-term morbidity and mortality of TP-IAT to optimize surgical technique and heparin dosing during islet autotransplantation. METHODS Eighty patients with chronic pancreatitis undergoing TP-IAT were reviewed. Primary outcome was to evaluate morbidity and mortality based on operative technique: classic (resection of antrum) vs pylorus-preserving. Secondary outcome was to evaluate the effect of heparin dosing (<60 vs ≥ 60 units/kg) during islet autotransplantation on postoperative hemorrhage and portal vein thrombosis (PVT) rates. RESULTS There was no 90-day mortality, and median length of stay was 9 days. All patients underwent an open operation with 53 (66%) pylorus-preserving resections. The 30-day morbidity rate was 39%, with no difference between operative technique (p = 0.82). The median dose was different for each heparin group (<60: 52 units/kg vs ≥ 60: 66 units/kg, p < 0.0001). No difference was observed in postoperative hemorrhage rates between heparin groups (<60: 9% vs ≥ 60: 9%, p = 0.97), with no known incidence of PVT. Median follow-up was 36 months (IQR, 14-71). Morbidity >30 days after TP-IAT was 43% with a higher rate in the pylorus-preserving group (55% vs 15%, p < 0.0001), mainly attributed to marginal ulcer formation (15% vs 0%, p = 0.03). CONCLUSIONS A classic TP-IAT technique should be universally adopted to achieve optimal outcomes, particularly to prevent the formation of marginal ulcers. When considering PVT versus postoperative hemorrhage risk, a lower heparin dose nearing 50 units/kg is optimal. These findings highlight potential areas for future improvement.

Abstract
Pancreatic islet transplantation is a reliable approach for treating insulin-deficient diabetes. This established β-cell replacement approach has shown considerable improvements in the last 2 decades. It has helped achieve metabolic homeostasis and safe outcomes for a subset of patients with type 1 diabetes and severe pancreatitis. Nutrition support, until recently, was considered as a secondary factor, merely identified as a means of providing all the necessary nutrients for such patients. However, new literature suggests that several factors, such as the route, timing, quantity, and composition of all the nutrients administered, have key disease-altering properties and are vital during the perioperative management of such patients. This review will highlight the benefits of performing the clinical islet transplantation on a subgroup of patients with type 1 diabetes and pancreatitis and summarize new data that identify the pivotal role of nutrition support as a critical intervention in their management.

Abstract
Background Numerous factors influence pancreatic islet survival following auto-transplantation. Of these, the host immune response in the early peri-operative period is one of the most important. In this study we investigated the role of the mannose-binding lectin (MBL)-dependent pathway in a group of total pancreatectomy (TP) islet auto-transplantation (TPIAT) patients and classified them as competent or deficient in MBL activity. Complement pathway activities, MBL protein and inflammatory cytokine concentrations were evaluated from eleven pancreatic islet auto-transplant patients from two institutions. Methods Eleven patients from two institutions were prospectively recruited. Serum was screened at different time points for 29 different cytokines and compared according to their MBL deficient or competent status. Twelve patients from previous TPIAT patients also underwent screening of MBL pathway activity. Results A total nine of twenty three patients (39%) were MBL pathway deficient. MCP-1, IL-7 and IL-1a concentrations were significantly lower in the MBL deficient cohort compared to the normal MBL group (P=0.0237, 0.0001 and 0.0051 respectively). IL-6 and IL-8 concentrations were significantly raised in the normal MBL group. MBL functional activity was lower in insulin-independent group compared to the insulin-dependent group. Conclusions Complement activation is an important, possibly damaging response during intra-portal islet infusion. MBL pathway deficiency appears common in this population and the cytokine response was attenuated in MBL pathway deficient patients. Therapeutic MBL pathway blockade during and following islet auto-transplantation (IAT) may improve islet survival and function and thereby clinical outcome.

Abstract
The selection of optimum surgical procedure from the range of reported operations for chronic pancreatitis (CP) can be difficult. The aim of this study is to explore geographical variation in reporting of elective surgery for CP. A systematic search of the literature was performed using the Scopus database for reports of five selected procedures for CP: duodenum-preserving pancreatic head resection, total pancreatectomy with islet autotransplantation (TPIAT), Frey pancreaticojejunostomy, thoracoscopic splanchnotomy and the Izbicki V-shaped resection. The keyword and MESH heading 'chronic pancreatitis' was used. Overall, 144 papers met inclusion criteria and were utilized for data extraction. There were 33 reports of duodenum-preserving pancreatic head resection. Twenty-one (64%) were from Germany. There were 60 reports of TPIAT, 53 (88%) from the USA. There are only two reports of TPIAT from outwith the USA and UK. The 34 reports of the Frey pancreaticojejunostomy originate from 12 countries. There were 20 reports of thoracoscopic splanchnotomy originating from nine countries. All three reports of the Izbicki 'V' procedure are from Germany. There is geographical variation in reporting of surgery for CP. There is a need for greater standardization in the selection and reporting of surgery for patients with painful CP.

Abstract
Pancreatic-islet transplantation is a safe and noninvasive therapy for type 1 diabetes. However, the currently applied site for transplantation, ie, the liver, is not the optimal site for islet survival. Because the human body has shortcomings in providing an optimal site, artificial transplantation sites have been proposed. Such an artificial site could consist of a polymeric scaffold that mimics the pancreatic microenvironment and supports islet function. Recently, remarkable progress has been made in the technology of engineering scaffolds. The polymer-islet interactions, the site of implantation, and scaffold prevascularization are critical factors for success or failure of the scaffolds. This article critically reviews these factors while also discussing translation of experimental studies to human application as well as the steps required to create a clinically applicable prevascularized, retrievable scaffold for implantation of insulin-producing cells for treatment of type 1 diabetes mellitus.

Abstract
Chronic pancreatitis (CP) is an inflammatory disease that causes progressive damage to
the pancreatic parenchyma with irreversible morphological changes and fibrotic replacement
of the gland. The risk factors associated with developing CP have been described as toxic
(e.g., alcohol and tobacco); idiopathic (e.g., unknown); genetic, autoimmune, recurrent
acute pancreatitis, and obstructive (the TIGAR-O system). Upon histological screening of
the pancreata from a cohort of CP patients who had undergone pancreatectomy for the
treatment of intractable pain in Leicester, UK, one sample showed a striking change in the
morphological balance toward an endocrine phenotype, most notably there was evidence of
substantial α cell genesis enveloping entire cross sections of ductal epithelium and the
presence of α cells within the ductal lumens. This patient had previously undergone a
partial pancreatectomy, had severe sclerosing CP, an exceptionally low body mass index
(15.2), and diabetes at the time the pancreas was removed, and although these factors have
been shown to induce tissue remodeling, such high levels of α cells was an unusual finding
within our series of patients. Due to the fact that α cells have been shown to be the
first endocrine cell type that emerges during islet neogenesis, future research profiling
the factors that caused such marked α cell genesis may prove useful in the field of islet
transplantation.

Abstract
BACKGROUND If conservative treatment of chronic pancreatitis is unsuccessful, surgery is an option. The choice of the most suitable surgical method can be difficult, as the indications, advantages, and disadvantages of the available methods have not yet been fully documented with scientific evidence. METHODS In April 2015, we carried out a temporally unlimited systematic search for publications on surgery for chronic pancreatitis. The target parameters were morbidity, mortality, pain, endocrine and exocrine insuffi - ciency, weight gain, quality of life, length of hospital stay, and duration of urgery. Differences between surgical methods were studied with network meta-analysis, and duodenum-preserving operations were compared with partial duodenopancreatectomy with standard meta-analysis. RESULTS Among the 326 articles initially identified, 8 randomized controlled trials on a total of 423 patients were included in the meta-analysis. The trials were markedly heterogeneous in some respects. There was no significant difference among surgical methods with respect to perioperative morbidity, pain, endocrine and exocrine insufficiency, or quality of life. Duodenumpreserving procedures, compared to duodenopancreatectomy, were associated with a long-term weight gain that was 3 kg higher (p <0.001; three trials), a mean length of hospital stay that was 3 days shorter (p = 0.009; six trials), and a duration of surgery that was 2 hours shorter (p <0.001; five trials). CONCLUSION Duodenum-preserving surgery for chronic pancreatitis is superior to partial duodenopancreatectomy in multiple respects. Only limited recommendations can be given, however, on the basis of present data. The question of the best surgical method for the individual patient, in view of the clinical manifestations, anatomy, and diagnostic criteria, remains open.

Abstract
OBJECTIVES Chronic pancreatitis (CP) is an infrequent but debilitating complication associated with CFTR mutations. Total pancreatectomy with islet autotransplantation (TPIAT) is a treatment option for CP that provides pain relief and preserves β-cell mass, thereby minimizing the complication of diabetes mellitus. We compared outcomes after TPIAT for CP associated with CFTR mutations to CP without CTFR mutations. METHODS All TPIATs performed between 2002 and 2014 were retrospectively reviewed: identifying 20 CFTR homozygotes (cystic fibrosis [CF] patients), 19 CFTR heterozygotes, and 20 age-/sex-matched controls without CFTR mutations. Analysis of variance and χ tests were used to compare groups. RESULTS Baseline demographics were not different between groups. Postoperative glycosylated hemoglobin and C-peptide levels were similar between groups, as were islet yield and rate of postoperative complications. At 1 year, 40% of CF patients, 22% of CFTR heterozygotes, and 35% of control patients were insulin independent. CONCLUSION Total pancreatectomy with islet autotransplantation is a safe, effective treatment option for CF patients with CP, giving similar outcomes for those with other CP etiologies.

Abstract
Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

Abstract
BACKGROUND Pain secondary to chronic pancreatitis is a difficult clinical problem to manage. Many patients are treated medically or undergo endoscopic therapy and surgical intervention is often reserved for those who have failed to gain adequate pain relief from a more conservative approach. RESULTS There have been a number of advances in the operative management of chronic pancreatitis over the last few decades and current therapies include drainage procedures (pancreaticojejunostomy, etc.), resection (pancreticoduodenectomy, etc.) and combined drainage/resection procedures (Frey procedure, etc.). Additionally, many centers currently perform total pancreatectomy with islet autotransplantation, in addition to minimally invasive options that are intended to tailor therapy to individual patients. DISCUSSION Operative management of chronic pancreatitis often improves quality of life, and is associated with low rates of morbidity and mortality. The decision as to which procedure is optimal for each patient should be based on a combination of pathologic changes, prior interventions, and individual surgeon and center experience.

Abstract
In the developed world, pancreatic surgery is becoming more common, with an increasing number of patients developing diabetes because of either partial or total pancreatectomy, with a significant impact on quality of life and survival. Although these patients are expected to consume increasing health care resources in the near future, many aspects of diabetes after pancreatectomy are still not well defined. The treatment of diabetes in these patients takes advantage of the therapies used in type 1 and 2 diabetes; however, no specific guidelines for its management, both immediately after pancreatic surgery or in the long term, have been developed. In this article, on the basis of both the literature and our clinical experience, we address the open issues and discuss the most appropriate therapeutic options for patients with diabetes after pancreatectomy.

Abstract
BACKGROUND Chronic pancreatitis is a painful and often debilitating disease. Total pancreatectomy with intra-portal islet autotransplantation (TP-IAT) is a treatment option that allows for pain relief and preservation of beta-cell mass, thereby minimizing the complication of diabetes mellitus. Cultures of harvested islets are often positive for bacteria, possibly due to frequent procedures prior to TP-IAT, such as endoscopic retrograde cholangiopancreatography (ERCP), stenting, or other operative drainage procedures. It is unclear if these positive cultures contribute to post-operative infections. HYPOTHESIS We hypothesized that positive cultures of transplant solutions will not be associated with increased infection risk. METHODS We reviewed retrospectively the sterility cultures from both the pancreas preservation solution used to transport the pancreas and the final islet preparation for intra-portal infusion of patients who underwent TP-IAT between April 2006 and November 2012. Two hundred fifty-one patients underwent total, near-total, or completion pancreatectomy with IAT and had complete sterility cultures. All patients received prophylactic peri-operative antibiotics. Patients with positive pancreas preservation solution or islet sterility cultures received further antibiotics for 5-7 d. Patients' medical records were reviewed for post-operative infections and causative organisms. RESULTS Of the 251 patients included, 151 (61%) had one or more positive bacterial cultures from the pancreas preservation solution or final islet product. Seventy-three of the 251 patients (29%) had an infectious complication. Thirty-four of the 73 (22%) patients with a post-operative infectious complication also had positive cultures. Only seven of 151 patients with positive cultures (4.7%) had an infectious complication caused by the same organism as that isolated from their pancreas or islet cell preparation. CONCLUSIONS In autologous islet preparations, isolation solutions frequently have positive cultures, but this finding is associated infrequently with clinical infection.

Abstract
BACKGROUND/OBJECTIVES Pancreatectomy with autologous islet transplantation has slowly been proving to be an effective way of treating chronic pancreatitis while lessening the effects of the concomitant surgical diabetes of pancreatectomy alone. Assessing patient quality of life and pain after the procedure is particularly important as intractable pain is the main complaint for which patients undergo total pancreatectomy. METHODS We used the Rand SF-36 and McGill pain questionnaires, and Visual Analogue Scale to assess patients preoperatively for quality of life and pain resulting from life with chronic pancreatitis. After undergoing total pancreatectomy with autologous islet transplantation (TPAIT), patients were followed with surveys administered at 1 month, 6 months, and 1 year to evaluate changes in their quality of life and pain experienced. RESULTS Significant improvement was reported in all components of every questionnaire within a year after surgery. Furthermore, patient reported mean scores on quality of life were found to fall within the range of the general population. CONCLUSIONS From our experience with 53 patients at the University of Arizona, after pancreatectomy with autologous islet transplantation patients reported a higher quality of life when compared to preoperative values, as well as reduced levels of pain.

Abstract
Autologous islet cell transplantation is a procedure performed to prevent or reduce the severity of diabetes after pancreatic resection. Autologous islet cell transplantation is being used almost exclusively in patients undergoing pancreatectomy because of painful, chronic pancreatitis, or multiple recurrent episodes of pancreatitis that is not controlled by standard medical and surgical treatments. Here, we discuss the possibility of extending the clinical indications for this treatment on the basis of our experience in patients undergoing pancreatic surgery for both nonmalignant and malignant diseases, including patients undergoing completion pancreatectomy because of anastomosis leakage after pancreaticoduodenectomy and those with pancreatic anastomosis deemed at high risk for failure.

Abstract
Autologous islet transplantation after total or semitotal pancreatectomy aims to preserve insulin secretory function and prevent the onset of diabetes. The major indication for pancreatectomy is chronic pancreatitis with severe abdominal pain, a benign pancreatic tumor, and trauma. The metabolic outcome of autologous islet transplantation is better than that of allogeneic transplantation and depends on the number of transplanted islets. Achieving islet isolation from a fibrous or damaged pancreas is one of the biggest challenges of autologous islet transplantation; a major complication is portal vein thrombosis after crude islet infusion. However, the incidence of portal vein thrombosis has decreased as islet preparation techniques have improved over time.

Abstract
Clinical islet transplantation has demonstrated success in treating type 1 diabetes. A current limitation is the intrahepatic portal vein transplant site, which is prone to mechanical stress and inflammation. Transplantation of pancreatic islets into alternative sites is preferable, but challenging, as it may require a three-dimensional vehicle to confer mechanical protection and to confine islets to a well-defined, retrievable space where islet neovascularization can occur. We have fabricated biostable, macroporous scaffolds from poly(dimethylsiloxane) (PDMS) and investigated islet retention and distribution, metabolic function, and glucose-dependent insulin secretion within these scaffolds. Islets from multiple sources, including rodents, nonhuman primates, and humans, were tested in vitro. We observed high islet retention and distribution within PDMS scaffolds, with retention of small islets (< 100 µm) improved through the postloading addition of fibrin gel. Islets loaded within PDMS scaffolds exhibited viability and function comparable to standard culture conditions when incubated under normal oxygen tensions, but displayed improved viability compared to standard two-dimensional culture controls under low oxygen tensions. In vivo efficacy of scaffolds to support islet grafts was evaluated after transplantation in the omental pouch of chemically induced diabetic syngeneic rats, which promptly achieved normoglycemia. Collectively, these results are promising in that they indicate the potential for transplanting islets into a clinically relevant, extrahepatic site that provides spatial distribution of islets as well as intradevice vascularization.

Abstract
Total pancreatectomy with immediate islet autotransplantation (IAT) can be an effective therapy in patients with chronic pancreatitis. Patient selection criteria for radical resection are not well defined. The impact of prior pancreatic surgery on quality of life outcomes in patients undergoing IAT is evaluated. A retrospective review of a prospectively collected database of patients undergoing pancreatectomy with islet autotransplantation was undertaken. Patients having undergone prior pancreatic resection and/or drainage procedures were compared with those without prior pancreatic operative history. Sixty-one patients underwent pancreatectomy with IAT for pancreatitis. Twenty-three patients had a prior history of pancreatic surgery (Group S); 38 had no prior history of pancreatic surgery (Group NS). Demographics between the groups were similar. Patients in Group S took more daily oral morphine equivalents and had a lower psychological quality of life preoperatively. Operative times and blood loss were similar between the patient groups. Islet yields were lower for patients in Group S. Postoperatively, daily insulin requirements at 6 months and 1 year trended higher in Group S. Postoperative quality of life scores at 6 months were improved and similar between the groups. Quality of life metrics continued to improve beyond 1 year of follow-up, with a trend toward greater improvement in the NS Group. Total pancreatectomy for chronic pancreatitis improves quality of life in patients with and without a prior history of pancreatic surgery. This study demonstrates that IAT without preceding pancreatic surgery may enhance outcomes measured by long term insulin requirements and quality of life.

Abstract
Total pancreatectomy with intrahepatic autoislet transplantation (TP/IAT) is a definitive treatment for relentlessly painful chronic pancreatitis. Pain relief is reported to be achieved in approximately 80% of patients. Overall, 30% to 40% achieve insulin independence, and 70% of recipients remain insulin independent for > 2 years, sometimes longer if > 300 000 islets are successfully transplanted. Yet, this approach to chronic pancreatitis is underemphasized in the general medical and surgical literature and vastly underused in the United States. This review emphasizes the history and metabolic outcomes of TP/IAT and considers its usefulness in the context of other, more frequently used approaches, such as operative intervention with partial pancreatectomy and/or lateral pancreaticojejunostomy (Puestow procedure), as well as endoscopic retrograde cholangiopancreatography with pancreatic duct modification and stent placement. Distal pancreatectomy and Puestow procedures compromise isolation of islet mass, and adversely affect islet autotransplant outcomes. Therefore, when endoscopic measures fail to relieve pain in severe chronic pancreatitis, we recommend early intervention with TP/IAT.

Isolation of human islets for autologous islet transplantation in children and adolescents with chronic pancreatitis. J Transplant 2012; 2012:642787.

Abstract
Chronic pancreatitis is an inflammatory disease of the pancreas that causes permanent changes in the function and structure of the pancreas. It is most commonly a complication of cystic fibrosis or due to a genetic predisposition. Chronic pancreatitis generally presents symptomatically as recurrent abdominal pain, which becomes persistent over time. The pain eventually becomes disabling. Once specific medical treatments and endoscopic interventions are no longer efficacious, total pancreatectomy is the alternative of choice for helping the patient achieve pain control. While daily administrations of digestive enzymes cannot be avoided, insulin-dependent diabetes can be prevented by transplanting the isolated pancreatic islets back to the patient. The greater the number of islets infused, the greater the chance to prevent or at least control the effects of surgical diabetes. We present here a technical approach for the isolation and preservation of the islets proven to be efficient to obtain high numbers of islets, favoring the successful treatment of young patients.

Abstract
Chronic pancreatitis (CP) is progressive inflammatory process of the pancreas. Abdominal pain remains the most debilitating symptom affecting quality of life, apart from diabetes mellitus, steatorrhoea and weight loss. The treatment options have evolved over the past decades and are aimed to provide durable relief in pain with possible attempt to support or improve the failing endocrine and exocrine functions. Surgical treatment options have shown the potentials to provide superior long term results compared to the pharmacological and endoscopic modalities and are broadly divided in to drainage, resection and combination hybrid procedures. The choice is based on the morphology of the main pancreatic duct, presence of head mass and associated complication of CP. Knowing the basic nature of the disease, total pancreatectomy seems a curative option but not without significant morbidities. There is recent paradigm shift towards organ sparing surgical procedures with reasonable success. Despite recent advancement in the treatment modalities for CP the overall quality of life remains moderate which need further addressal.

Abstract
The loss of pancreatic parenchyma resulting from pancreatic resection causes an extreme disruption of glucose homeostasis known as pancreatogenic diabetes. This form of glucose intolerance is different from the other forms of diabetes mellitus in that affected individuals suffer frequent episodes of iatrogenic hypoglycemia. The development of sophisticated surgical procedures, improved postoperative care, and the capacity for early diagnosis of disease has prolonged life expectancy after pancreatic resection. For this reason, pancreatogenic diabetes is now attracting attention as the primary factor influencing quality of life in patients who have undergone this procedure. The incidence of new-onset diabetes mellitus after pancreatic resection increases as the follow-up period after surgery becomes longer and is related to the progression of underlying disease, the type of surgery, and the extent of resection. The pathophysiology of pancreatogenic diabetes is related to pancreatic hormone deficiency and the altered responses of the liver and peripheral organs to lower than normal hormone levels. Hyperglycemia occurs when the amount of insulin produced or administered is insufficient because of unsuppressed hepatic glucose production secondary to a deficiency in pancreatic polypeptide. In contrast, patients lapse into hypoglycemia when insulin is barely excessive because of enhanced peripheral insulin sensitivity and glucagon deficiency. Nutritional state, pancreatic exocrine function and intestinal function also affect glycemic control. Insulin replacement is considered to be the main treatment option for insulin dependent pancreatogenic diabetes. Pancreatic polypeptide replacement and islet autotransplantation have potential as new approaches to treating patients with pancreatogenic diabetes after pancreatic resection. and IAP.

Abstract
BACKGROUND Portal vein thrombosis can be a devastating, but often overlooked, complication of hepatobiliary procedures. Symptoms of acute portal vein thrombosis range from nondescript abdominal pain to septic shock secondary to mesenteric ischemia. DISCUSSION The surgeon must be cognizant of these symptoms and the potential for portal vein thrombosis after any hepatobiliary procedures as an expedient diagnosis and treatment is necessary in order to prevent thrombus propagation, bowel ischemia, and death. This report outlines the symptoms, diagnosis, and a review of the literature on the treatment of acute portal vein thrombosis after hepatobiliary surgery with a special note made regarding a case of portal vein thrombosis after pancreatectomy and autologous islet cell transplantation.

Abstract
OBJECTIVES This study examined 85 consecutive patients undergoing total pancreatectomy (+/-islet cell transplant), examining pain relief, insulin requirements, and glycemic control postoperatively. METHODS A prospective database of all patients undergoing total pancreatectomy for chronic pancreatitis was used to record preoperative and postoperative details from 1996 to 2006. RESULTS There were 3 postoperative deaths (1 islet recipient and 2 nonislet patients). The median number of acute admissions for pain fell from 5 to 2 after pancreatectomy, and the median length of stay from 6.2 days to 3.3 days. At 12 months postoperatively, the number of patients on regular opiate analgesia fell from 90.6% to 40.2% and by 5 years to 15.9%. There was a significant reduction in the patients' visual analogue pain score after surgery from 9.7 to 3.7 (P < 0.001). Five patients were insulin independent at 5 years. Median 24-hour insulin requirements were significantly lower in the islet group (15.5 vs 40 units at 5 years postoperatively; P < 0.001). CONCLUSIONS Total pancreatectomy is effective in reducing pain and dependence on opioid analgesia in patients with chronic pancreatitis. The addition of an islet cell transplant results in a reduction in 24-hour insulin demands, as well as potentially achieving insulin independence.

Abstract
UNLABELLED Total pancreatectomy is considered the final resort in the treatment of chronic pancreatitis; however, here we show that simultaneous islet autotransplantation can abrogate the onset of diabetes. METHODS : In Leicester, 46 patients have now undergone total pancreatectomy with immediate islet auto transplant, and they have received a median of 2246 islet equivalent (IEQ)/kg body weight (range, 405-20,385 IEQ/kg body weight). RESULTS : Twelve patients have shown periods of insulin independence, for a median of 16.5 months (range, 2-63 months), and 5 remain insulin independent. Over the 10 years of follow-up, there has been a notable increase in insulin requirement per kilogram per day, and percentage of glycosylated hemoglobin levels have increased significantly (r = 0.66, P = 0.01). However, 100% of patients tested were C-peptide positive at their most recent assessment, and high fasting and stimulated C-peptide values recorded at 10 years after transplantation, 1.44 (range, 1.09-1.8 ng/mL) and 2.86 ng/mL (range, 1.19-4.53 ng/mL), respectively, suggest significant graft function in the long term. In addition, median serum creatinine has increased very little after the operation (71 nmol/L [range, 49-125 nmol/L] atpreoperation vs 76.5 nmol/L [range 72-81 nmol/L] at year 10), suggesting no diabetic nephropathy. CONCLUSIONS : Although there is a notable decline in islet function after islet auto transplant, there is still evidence of significant long-term insulin secretion and possible protection against diabetic complications.

Abstract
Because of poor outcomes with traditional surgical management, total pancreatectomy with autologous islet transplantation (TPAIT) has been heralded as a breakthrough in the management of severe chronic pancreatitis intractable to medical management. To assess the impact of TPAIT on a pancreatobiliary disease-based center, a retrospective review and analysis of patients who underwent TPAIT after failing traditional surgical management was undertaken. Seven patients who underwent TPAIT were identified. Patient hospitalizations, emergency department visits, and clinic visits in the year pre- and post-TPAIT were tabulated. Average body weights and serum prealbumin were recorded during the year pre- and post-TPAIT. Based on the number of hospitalizations, clinic visits, and emergency department visits as an indicator of overall symptom severity, patients experienced an improvement in symptoms during the 12 months after TPAIT. Prealbumin values remained stable during the postoperative year. An observed decrease in weight suggests that other factors may be impacting the overall state of nutrition. The impact of TPAIT on the surgical management of chronic pancreatitis is limited in scope and benefit and continues to require careful analysis to identify appropriate candidates.

Abstract
Total pancreatectomy and islet autotransplantation are done for chronic pancreatitis with intractable pain when other treatment measures have failed, allowing insulin secretory capacity to be preserved, minimizing or preventing diabetes, while at the same time removing the root cause of the pain. Since the first case in 1977, several series have been published. Pain relief is obtained in most patients, and insulin independence preserved long term in about a third, with another third having sufficient beta cell function so that the surgical diabetes is mild. Islet autotransplantation has been done with partial or total pancreatectomy for benign and premalignant conditions. Islet autotransplantation should be used more widely to preserve beta cell mass in major pancreatic resections.

Abstract
Islet transplantation is an appealing procedure able to improve glycemic control in type 1 diabetic patients. However, the possible side effects that may be induced by immunosuppressive therapy limit its application to a select number of patients for whom the risk of immunosuppressants' side effects can be justified. For patients with type 1 diabetes mellitus-who will take immunosuppressants regardless, as they require a solid organ transplant-islet infusion can be an interesting therapeutic option for improving metabolic compensation, whenever pancreas transplant is not possible. Hence, islet infusion can be an important therapeutic option for patients with secondary diabetes mellitus even when a minor pancreatic endocrine function remains. For these patients, results may be better than those obtained with islet infusion for patients with type 1 diabetes mellitus thanks to the lack of autoimmune reaction to the infused islets. The final result is the improvement of the glycemic compensation and most likely also an extension of the graft survival.

Abstract
Total pancreatectomy (TP) for chronic pancreatitis (CP) has not gained widespread acceptance because of concerns regarding technical complexity, diabetic complications, and uncertainty with respect to long-term pain relief. Records of patients having TP from 1997 to 2005 were reviewed. Patient presentation, etiology of disease, and the indication for TP were examined. Operative results were analyzed. Long-term results were critically assessed, including narcotic usage and the need for re-admission. Postoperative quality of life (QOL) was assessed by the SF-36 health survey. During the study period, 7 patients with CP had TP, and 28 had other operations. The etiology of CP was alcohol in four and hereditary pancreatitis in three. The indication for surgery was pain and weight loss. Preoperatively, all patients used narcotics chronically and two had insulin-dependent diabetes. Four had TP after failed previous surgical procedures. Endoscopic retrograde cholangiopancreatography and computed tomography demonstrated small ducts and atrophic calcified glands. The mean length of the operation was 468 minutes, and only two patients required transfusion. There were no biliary anastomotic complications. The mean length of stay was 14 days. Major morbidity was limited to a single patient with a leak from the gastrojejunal anastomosis. Thirty-day mortality was zero, with one late death unrelated to the surgical procedure or diabetes. The mean length of follow-up was 46 months. All patients remained alcohol and narcotic free. No patient was readmitted with a diabetic complication. When compared with the general population, QOL scores were diminished but reasonable. We conclude that TP is indicated in hereditary pancreatitis and in those with an atrophic, calcified pancreas with small duct disease; that TP is technically arduous but can be completed with very low morbidity and mortality; and that on long-term follow-up, pain relief and abstinence from alcohol and narcotics was excellent with an acceptable QOL.

Abstract
BACKGROUND For patients who suffer from severe chronic pancreatitis, total pancreatectomy can alleviate pain, and islet autotransplantation (IAT) might preserve endocrine function and circumvent the complications of diabetes. Factors that determine success after this operation have not been clearly defined. STUDY DESIGN From 2000 to 2004, 45 total or subtotal pancreatectomies with IAT were performed. Patient characteristics, narcotic usage and insulin requirements were recorded at routine followup. Narcotic usage was standardized by conversion to morphine equivalents (MEs). Univariate and multivariate statistical analyses were performed to determine factors associated with insulin and narcotic independence. RESULTS Forty-five patients (30 women, 15 men), with a mean age of 39 years (range 16 to 62 years) underwent total or completion (n=41) or subtotal (n=4) pancreatectomies with IAT. Forty percent of patients were insulin free after a mean followup of 18months (range 1 to 46months). Factors associated in univariate analyses with insulin independence included female gender (p=0.004), lower body weight (kg) (p=0.04), more islet equivalents per kg body weight (IEQ/kg) transfused (<0.05), lower mean insulin requirement for the first 24hours postoperation (p=0.002), and lower mean insulin requirement at discharge (p=0.0005). A multiple logistic regression using gender, body mass index, and IEQ/kg identified female gender as the only notable variable associated with insulin independence. There was a notable reduction (p < 0.0001) of postoperative MEs (mean 90 mg) compared with preoperative MEs (mean 206 mg) for the entire cohort; 58% of patients are narcotic independent. In the subset of patients with>5months followup (n=32), 23 (72%) are narcotic free, with a substantial decrease in ME usage (p=0.01). CONCLUSIONS The likelihood of glycemic control after IAT is related to both patient characteristics and islet cell mass. Based on these data, more islet cells may be required for insulin independence than previously thought.

Abstract
Clinical islet transplantation in liver has achieved normoglycemia. However, this site may not be ideal for islet survival. To create a more optimal site for islet transplantation, we have developed a construct with biodegradable scaffolds. Islets were seeded in scaffolds and transplanted into the epididymal fat pad of diabetic BALB/c mice. Controls included islets transplanted underneath the kidney capsule or into the fat pad without scaffolds. All animals with islets in scaffolds or the kidney became normoglycemic and maintained this metabolic state. When islets were transplanted without scaffolds the time to achieve normoglycemia was significantly increased and less than 45% of mice survived. An oral glucose tolerance test was performed on the scaffold and kidney groups with similar blood glucose levels and area under the curve values between the groups. Grafts were removed at more than 100 days posttransplantation and all animals became hyperglycemic. There was no significant difference in insulin content between the grafts and all grafts were well vascularized with insulin-positive beta cells. Therefore, islets in scaffolds function and restore diabetic animals to normoglycemic levels, similar to islets transplanted underneath the kidney capsule, suggesting scaffolds can be used to create a site for islet transplantation.

Abstract
PURPOSE Total pancreatectomy and autologous islet cell transplantation are being investigated as a novel surgical treatment for patients with chronic pancreatitis. Preliminary data has demonstrated the presence of enteric bacteria in solutions used to harvest islet cells. Subsequently, we started culturing autologous islet solutions to determine whether any concordance existed between these cultures and postoperative infectious complications. METHODS A retrospective analysis evaluated microbiologic cultures between July 2000 and November 2003; 33 patients underwent total or completion pancreatectomy and islet cell transplantation. Five patients were excluded due to incomplete culture data. Aerobic, anaerobic and fungal cultures were performed on all islet preparation solutions. Patient charts were examined for postoperative infectious complications. Microbiologic data from these infections was compared to pretransplant islet cultures. Islet cells from each patient were tested in vitrofor both function and viability. RESULTS Of the 28 patients, 25 (89.3%) had bacterial culture-positive media solutions. Only 4 patients (14.3%) had an infectious complication from which bacteria was isolated that corresponded to bacteria in their islet cell preparation. In vitro islet cell viability was greater than 95% in the pretransplant aliquots. CONCLUSION These results suggest that transplantation of bacterial-positive islet cell solutions does not appear to increase the risk of postoperative infectious complications or impact islet cell viability. Therefore, prolonged antibiotic treatment against these specific bacteria beyond the perioperative period does not seem warranted.

Abstract
Extensive pancreatectomy (EP) may increase the resection rate of pancreatic adenocarcinoma (PA). Unfortunately, EP often results in unstable diabetes. Recently, islet autotransplantation (auto-Tx) has offered the potential to prevent this metabolic disorder. Because of the fear of contamination of prepared islets by malignant cells, this procedure has so far not been used as a treatment for PA. We herein report a case of a 63-year-old nondiabetic patient who underwent EP combined with islet auto-Tx in an emergency operation following histologically proved R(0)-resection for PA (pT(3)pN(1)G(2)). Islets were isolated from the excised pancreas using a continuous digestion filtration device. The resultant preparation was injected into the portal vein. Owing to the moderate fasting hyperglycemia, postoperative exogenous insulin therapy was necessary (26 U/d). After discharge, the patient's daily insulin dose was gradually reduced. At 1-year follow-up the fasting C-peptide level was 0.66 ng/mL, and an oral glucose tolerance test (oGTT) and an intravenous (IV) glucagon stimulation (GS) showed functioning engrafted islets. The K-ras mutations were detected in the paraffin-embedded PA, but not in the prepared islets or in the peripheral blood. Computed tomographic (CT) imaging revealed neither local tumor recurrence nor liver metastases. At 2-year follow-up, the patient was on a balanced food regimen and gaining weight. Although he remains insulin-dependent (16 U/d), he is metabolically stable (HbA(1)(c) 5.9%). The fasting C-peptide level is 0.68 ng/mL. The peak value of C-peptide in response to oGTT was 0.92 ng/mL and to GS 0.89 ng/mL. At this time Ca19-9 and CEA are increased to 35.3 U/mL and 19.2 ng/mL, respectively. The patient died 2.5 years after operation owing to tumor recurrence. There was no evidence for liver metastases. We postulate that histologic evaluation (R(0)-resection) and detection of K-ras mutations may be useful techniques. However, islet auto-Tx after EP for adenocarcinoma should only be regarded for rescue therapy. Studies on strategies to exclude possible contamination of islet tissue with carcinoma cells are critically important.

Abstract
The management of patients with chronic pancreatitis (CP) remains a challenging problem. Main indications for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The main goal of surgical treatment is improvement of patient quality of life. The surgical treatment approach usually involves proximal pancreatic resection, but lateral pancreaticojejunal drainage may be used for large-duct disease. The newer duodenum-preserving head resections of Beger and Frey provide good pain control and preservation of pancreatic function. Thoracoscopic splanchnicectomy and the endoscopic approach await confirmatory trials to confirm their efficiency in the management of CP. Common bile duct obstruction is addressed by distal Roux-en-Y choledochojejunostomy but when combined with dudodenal obstruction must be treated by pancreatic head resection. Pancreatic ascites due to disrupted pancreatic duct should be treated by internal drainage. The approach to CP is multidisciplinary, tailoring the various therapeutic options to meet each individual patient's needs.

J Am Coll Surg 2004; 198:559-67; discussion 568-9.

Abstract
BACKGROUND Total pancreatectomy to treat chronic pancreatitis is associated with severe diabetic control problems in 15% to 75% of patients, causing up to 50% of deaths late postoperatively. We report our experience with islet autotransplants at the time of, or with pancreas allotransplants after, total pancreatectomy. STUDY DESIGN Between February 1, 1977, and June 30, 2003, we performed 112 islet autotransplants at the time of total pancreatectomy; we also performed 20 pancreas allotransplants in 13 patients who had already undergone total pancreatectomy months to years earlier. RESULTS Islet autotransplants at the time of total pancreatectomy in patients who had not had previous operations on the body and tail of the pancreas were associated with a high islet yield (>2,500 islet equivalents/kg body weight), and >70% of the recipients achieved complete insulin independence. In contrast, a previous distal pancreatectomy or a Puestow drainage procedure was associated with a low islet yield in 75% of them and with complete insulin independence in <20%. A pancreas allotransplant after total pancreatectomy was not associated with any transplant-related mortality at 1 and 3 years posttransplant. The pancreas graft survival rate at 1 year posttransplant was 77% with tacrolimus-based immunosuppression (versus 67% with cyclosporine). Enteric (over bladder) drainage was preferred to manage exocrine graft secretions, to cure pancreatectomy-induced endocrine and exocrine insufficiency. CONCLUSIONS Our series shows that pancreas allotransplants can be performed without transplant-related mortality and, when tacrolimus-based immunosuppression is used, with 1-year pancreas graft survival rates >75%. In contrast to a simultaneous islet autotransplant, a pancreas allotransplant has the disadvantage of requiring lifelong immunosuppression, but the advantage of not only curing endocrine but also exocrine insufficiency. Both transplant options, if successful, improve the recipient's quality of life.
