Abstract
Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical treatment option for patients with chronic pancreatitis who have not responded to other therapies. TP offers pain relief whereas IAT preserves beta cell mass to reduce endocrine insufficiency. During the surgical procedure, the entire pancreas is removed. Islet cells from the pancreas are then isolated, purified, and infused into the liver via the portal vein. Successful TPIAT relieves pain for a majority of patients but is not without obstacles, specifically gastrointestinal, exocrine, and endocrine challenges. The postoperative phase can be complicated by gastrointestinal symptoms causing patients to have difficulty regaining adequate oral intake. Enteral nutrition is frequently provided as a bridge to oral diet. Patients undergoing TPIAT must be monitored for macronutrient and micronutrient deficiencies following the procedure. Exocrine insufficiency must be treated lifelong with pancreatic enzyme replacement therapy. Endocrine function must be monitored and exogenous insulin provided in the postoperative phase; however, a majority of patients undergoing TPIAT require little or no long-term insulin. Although TPIAT can be a successful option for patients with chronic pancreatitis, nutrition-related concerns must be addressed for optimal recovery.

Abstract
Pancreatic islet transplantation is a minimally invasive procedure aiming to reverse the effects of insulin deficiency in patients with type 1 diabetes (T1D) by transplanting pancreatic beta cells. Overall, pancreatic islet transplantation has improved to a great extent, and cellular replacement will likely become the mainstay treatment. We review pancreatic islet transplantation as a treatment for T1D and the immunological challenges faced. Published data demonstrated that the time for islet cell transfusion varied between 2 and 10 h. Approximately 54% of the patients gained insulin independence at the end of the first year, while only 20% remained insulin-free at the end of the second year. Eventually, most transplanted patients return to using some form of exogenous insulin within a few years after the transplantation, which imposed the need to improve immunological factors before transplantation. We also discuss the immunosuppressive regimens, apoptotic donor lymphocytes, anti-TIM-1 antibodies, mixed chimerism-based tolerance induction, induction of antigen-specific tolerance utilizing ethylene carbodiimide-fixed splenocytes, pretransplant infusions of donor apoptotic cells, B cell depletion, preconditioning of isolated islets, inducing local immunotolerance, cell encapsulation and immunoisolation, using of biomaterials, immunomodulatory cells, etc.

World J Transplant 2023; 13:10-24. [PMID: 36687559 PMCID: PMC9850868 DOI: 10.5500/wjt.v13.i1.10] [Citation(s) in RCA: 4] [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
Total pancreatectomy is a major complex surgical procedure involving removal of the whole pancreatic parenchyma and duodenum. It leads to lifelong pancreatic exocrine and endocrine insufficiency. The control of surgery-induced diabetes (type 3) requires insulin therapy. Total pancreatectomy with autologous islet transplantation (TPAIT) is performed in order to prevent postoperative diabetes and its serious complications. It is very important whether it is safe and beneficial for patients in terms of postoperative morbidity and mortality, and long-term results including quality of life. Small duct painful chronic pancreatitis (CP) is a primary indication for TPAIT, but currently the indications for this procedure have been extended. They also include hereditary/genetic pancreatitis (HGP), as well as less frequent indications such as benign/borderline pancreatic tumors (intraductal papillary neoplasms, neuroendocrine neoplasms) and "high-risk pancreatic stump". The use of TPAIT in malignant pancreatic and peripancreatic neoplasms has been reported in the worldwide literature but currently is not a standard but rather a controversial management in these patients. In this review, history, technique, indications, and contraindications, as well as short-term and long-term results of TPAIT, including pediatric patients, are described.

Atypical Hepatic Steatosis Patterns on MRI After Total Pancreatectomy With Islet Autotransplant. AJR Am J Roentgenol 2021; 217:100-106. [PMID: 33909467 DOI: 10.2214/ajr.20.23303] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/18/2022]
Abstract
OBJECTIVE. The purpose of this retrospective study was to investigate the prevalence and patterns of hepatic steatosis after total pancreatectomy with islet autotransplant (TPIAT) and to determine if the unique patterns of steatosis seen in this study correlated with islet graft function. MATERIALS AND METHODS. Fifty-two subjects who had undergone MRI after TPIAT were reviewed for the presence of hepatic steatosis. Patterns of steatosis were categorized into three groups: normal (no steatosis), homogeneous, and atypical. Demographics and outcomes were compared between the groups. Islet graft function 1 year after surgery was classified as full graft function, partial graft function, and graft failure. Statistical analysis was performed using ANOVA, Kruskal-Wallis, and Fisher exact tests. RESULTS. Sixty-three percent of patients had steatosis present on MRI after TPIAT (33 subjects of 52 total), and 48% (25/52) exhibited an atypical pattern. Twenty-four percent of the 37 patients who had MRI examinations before TPIAT showed steatosis preoperatively, yet none of these showed an atypical steatosis pattern. Islet graft function was not statistically different between the groups. The only statistically significant variable difference between the groups was body mass index (p = .02). CONCLUSION. Steatosis is a common finding after TPIAT, and atypical steatosis patterns frequently develop after the procedure, implying that the procedure itself is the causal factor. There was no correlation between islet graft function and the presence or pattern of steatosis. An atypical pattern of hepatic steatosis can therefore be considered an incidental finding after TPIAT and does not require additional workup or treatment.

Sterility Cultures Following Pancreatectomy with Islet Autotransplantation in the Pediatric Population: Do They Matter? J Gastrointest Surg 2020; 24:2526-2535. [PMID: 31745897 DOI: 10.1007/s11605-019-04413-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Accepted: 09/11/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Pancreatectomy with islet autotransplantation (IAT) is a treatment option for children with debilitating chronic pancreatitis. Sterility cultures from preservation solutions are often positive, yet their impact has not been well studied in children. METHODS A retrospective review of all patients who underwent IAT from 2015 to 2018 at a single institution was performed. Sterility culture data were obtained from both the pancreas transport and islet transplant media. All patients received prophylactic perioperative meropenem and vancomycin for 72 h per our protocol. If cultures resulted positive, antibiotics were extended for a total of 7 days. Primary outcomes were postoperative fever and 30-day infectious complications. RESULTS Forty-one patients underwent IAT during the study period. Seventeen (41.5 %) patients had negative cultures of both the transport and transplant media, while 24 (58.5 %) patients had a positive culture from either sample. Of these patients, 13 (31.7 %) were positive in both, 10 (24.4 %) were positive in only the transport media, and 1 (2.4 %) was positive in only the transplant media. Patients with positive transplant media were similar with regard to age, gender, etiology, and disease duration compared to those with negative transplant media (all p > 0.05), but the positive group was more likely to have a pancreatic stent in place at the time of surgery (38.5 % vs. 4.2 %, p = 0.01). The overall postoperative infectious complication rate was 31.2 % (n = 13). No difference was detected between the transplant positive and negative culture groups in postoperative fever or 30-day infectious complications (p > 0.05 for each). CONCLUSION An existing pancreatic stent at the time of pancreatectomy with IAT is a risk factor for positive sterility cultures. However, positive islet transplant media culture was not associated with increased risk of post-IAT infection or morbidity in the setting of an empiric antibiotic protocol. Future work is necessary to study the optimal perioperative antibiotic regimen in pediatric IAT.

Abstract
BACKGROUND Portal vein thrombosis (PVT) is a serious complication of total pancreatectomy and autologous islet cell transplant (TPAIT); therefore, portal flow dynamics are monitored by Doppler ultrasound postoperatively. The practical value of scheduled Doppler ultrasound examinations and the relationship between portal vein velocity, liver function, and complications have not been clearly studied. METHODS A retrospective review of 16 TPAIT was performed. Correlation analysis of portal vein velocity with indices of liver function, portal pressure, and volume of islet cells infused was conducted. RESULTS There was no correlation between portal vein velocity and postoperative liver function tests (LFTs). Larger volume of islet cells infused and higher intraoperative portal pressure correlated with decreased postoperative portal flow. There was no significant difference in portal pressure, portal vein velocity, or LFTs between those with normal and abnormal pre-infusion liver histopathology. While no PVT occurred, there were two cases of postoperative bleeding related to anticoagulation. CONCLUSION Segmental portal vein velocities are low in the setting of high tissue volume and portal pressure, but are not associated with variation in LFTs. Therefore, patient management in response to changes in velocities without clinical symptoms may be unnecessary.

Abstract
OBJECTIVES A selective therapy for pancreatitis is total pancreatectomy and islet autotransplantation. Outcomes and geographical variability of patients who had total pancreatectomy (TP) alone or total pancreatectomy with islet autotransplantation (TPIAT) were assessed. METHODS Data were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample database. Weighed univariate and multivariate analyses were performed to determine the effect of measured variables on outcomes. RESULTS Between 2002 and 2013, there were 1006 TP and 825 TPIAT in patients with a diagnosis of chronic pancreatitis, and 1705 TP and 830 TPIAT for any diagnosis of pancreatitis. The majority of the TP and TPIAT were performed in larger urban hospitals. Costs were similar for TP and TPIAT for chronic pancreatitis but were lower for TPIAT compared with TP for any type of pancreatitis. The trend for TP and TPIAT was significant in all geographical areas during the study period. CONCLUSIONS There is an increasing trend of both TP and TPIAT. Certain groups are more likely to be offered TPIAT compared with TP alone. More data are needed to understand disparities and barriers to TPIAT, and long-term outcomes of TPIAT such as pain control and glucose intolerance need further study.

Abstract
Pancreatic islet transplantation has become an established approach to β-cell replacement therapy for the treatment of insulin-deficient diabetes. Recent progress in techniques for islet isolation, islet culture, and peritransplant management of the islet transplant recipient has resulted in substantial improvements in metabolic and safety outcomes for patients. For patients requiring total or subtotal pancreatectomy for benign disease of the pancreas, isolation of islets from the diseased pancreas with intrahepatic transplantation of autologous islets can prevent or ameliorate postsurgical diabetes, and for patients previously experiencing painful recurrent acute or chronic pancreatitis, quality of life is substantially improved. For patients with type 1 diabetes or insulin-deficient forms of pancreatogenic (type 3c) diabetes, isolation of islets from a deceased donor pancreas with intrahepatic transplantation of allogeneic islets can ameliorate problematic hypoglycemia, stabilize glycemic lability, and maintain on-target glycemic control, consequently with improved quality of life, and often without the requirement for insulin therapy. Because the metabolic benefits are dependent on the numbers of islets transplanted that survive engraftment, recipients of autoislets are limited to receive the number of islets isolated from their own pancreas, whereas recipients of alloislets may receive islets isolated from more than one donor pancreas. The development of alternative sources of islet cells for transplantation, whether from autologous, allogeneic, or xenogeneic tissues, is an active area of investigation that promises to expand access and indications for islet transplantation in the future treatment of diabetes.

Abstract
We investigated six indices based on a single fasting blood sample for evaluation of the beta-cell function after total pancreatectomy with islet autotransplantation (TP-IAT). The Secretory Unit of Islet Transplant Objects (SUITO), transplant estimated function (TEF), homeostasis model assessment (HOMA-2B%), C-peptide/glucose ratio (CP/G), C-peptide/glucose creatinine ratio (CP/GCr) and BETA-2 score were compared against a 90-min serum glucose level, weighted mean C-peptide in mixed meal tolerance test (MMTT), beta score and the Igls score adjusted for islet function in the setting of IAT. We analyzed values from 32 MMTTs in 15 patients after TP-IAT with a follow-up of up to 3 years. Four (27%) individuals had discontinued insulin completely prior to day 75, while 6 out of 12 patients (50%) did not require insulin support at 1-year follow-up with HbA1c 6.0% (5.5-6.8). BETA-2 was the most consistent among indices strongly correlating with all reference measures of beta-cell function (r = 0.62-0.68). In addition, it identified insulin independence (cut-off = 16.2) and optimal/good versus marginal islet function in the Igls score well, with AUROC of 0.85 and 0.96, respectively. Based on a single fasting blood sample, BETA-2 score has the most reliable discriminant value for the assessment of graft function in patients undergoing TP-IAT.

Abstract
PURPOSE OF REVIEW While there has been a growing utilization of total pancreatectomy with islet autotransplantation (TPIAT) for patients with medically refractory chronic pancreatitis over the past few decades, there remains a lack of consensus clinical guidelines to inform the counseling and management of patients undergoing TPIAT. In this article, we review the current clinical practice and published experience of several TPIAT centers, outline key aspects in managing patients undergoing TPIAT, and discuss the glycemic outcomes of this procedure. RECENT FINDINGS Aiming for lower inpatient glucose targets immediately after surgery (usually 100-120 mg/dl), maintaining all patients on subcutaneous insulin for at least 3 months to "rest" islets before an attempt is made to wean insulin, and close outpatient endocrinology follow-up after TPIAT particularly in the first year is common and related to better outcomes. Although TPIAT procedures and glycemic outcomes may differ across surgical centers, overall, approximately one third of patients are insulin independent at 1 year after TPIAT. Higher islet yield and lower preoperative glucose levels are among the strongest predictors of short-term post-operative insulin independence. Beyond 1 year post-operatively, the clinical management and long-term glycemic outcomes of patients after TPIAT are more variable. A multidisciplinary approach is essential in optimizing the preoperative, inpatient, and post-operative management and counseling of patients about the expected glycemic outcomes after surgery. Consensus guidelines for the clinical management of diabetes after TPIAT and harmonization of data collection protocols among TPIAT centers are needed to address the current knowledge gaps in clinical care and research and to optimize glycemic outcomes after TPIAT.

Abstract
OBJECTIVES Total pancreatectomy with islet autotransplantation (TPIAT) offers symptom relief to highly selected patients with recurrent acute and/or chronic pancreatitis. However, with variable clinical response, it is important to refine islet manipulation technique and patient selection criteria. This study explores the variables associated with high islet cell yield, a driver of success in TPIAT. METHODS This study evaluated patients who underwent TPIAT at Dartmouth-Hitchcock Medical Center from 2012 to 2016. Odds ratios were calculated for various patient and procedural characteristics. The primary clinical outcome was the number of isolated islet equivalents per kilogram body weight. RESULTS Thirty-eight patients met inclusion criteria. Patients with no computed tomography or magnetic resonance imaging evidence of chronic pancreatitis, without pancreatic duct stones, and without parenchymal stones were associated with higher odds of success (P = 0.02, P = 0.02, and P = 0.002, respectively). Patients with preoperative glycated hemoglobin greater than 5.6, with islet cell suspensions positive for cultures, and with positive gram stains were associated with lower odds of success (P = 0.02, P = 0.01, and P = 0.02, respectively). CONCLUSIONS Factors that diminish a successful islet cell harvest during TPIAT include the presence of infected islets, an elevated preoperative glycated hemoglobin, and the presence of pancreatic duct stones.

Abstract
PURPOSE OF REVIEW The first total pancreatectomy and islet autotransplantation (TP-IAT) was performed for chronic pancreatitis in 1977 with the goal to ameliorate the pain and simultaneously preserve islet function. We reviewed the recent medical literature regarding indications, patient suitability, current outcomes, and challenges in TP-IAT. RECENT FINDINGS Current indications for TP-IAT include intractable pain secondary to chronic pancreatitis (CP) or acute recurrent pancreatitis (ARP) with failed medical and endoscopic/surgical management. Independent studies have shown that TP-IAT is associated with elimination or significant improvement in pain control and partial or full islet graft function in the majority of patients. In single-center cost analyses, TP-IAT has been suggested to be more cost-effective than medical management of chronic pancreatitis. While initially introduced as a surgical option for adults with long-standing chronic pancreatitis, TP-IAT is now often utilized in children with chronic pancreatitis and in children and adults with intractable acute recurrent pancreatitis. The surgical procedure has evolved over time with some centers offering minimally invasive operative options, although the open approach remains the standard. Despite many advances in TP-IAT, there is a need for further research and development in disease diagnosis, patient selection, optimization of surgical technique, islet isolation and quality assessment, postoperative patient management, and establishment of uniform metrics for data collection and multicenter studies. TP-IAT is an option for patients with otherwise intractable acute recurrent or chronic pancreatitis which presents potential for pain relief and improved quality of life, often with partial or complete diabetes remission.

Abstract
Importance Pain management of patients with chronic pancreatitis (CP) can be challenging. Laparoscopy has been associated with markedly reduced postoperative pain but has not been widely applied to total pancreatectomy with islet autotransplantation (TPIAT). Objective To examine the feasibility of using laparoscopic TPIAT (L-TPIAT) in the treatment of CP. Design, Setting, and Participants Thirty-two patients with CP presented for TPIAT at a tertiary hospital from January 1, 2013, through December 31, 2015. Of the 22 patients who underwent L-TPIAT, 2 patients converted to an open procedure because of difficult anatomy and prior surgery. Pain and glycemic outcomes were recorded at follow-up visits every 3 to 6 months postoperatively. Main Outcomes and Measures Operative outcomes included operative time, islet isolation time, warm ischemia time, islet equivalent (IE) counts, estimated blood loss, fluid resuscitation, and blood transfusions. Postoperative outcomes included length of stay, all-cause 30-day readmission rate, postoperative complications, mortality rate, subjective pain measurements, opioid use, random C-peptide levels, insulin requirements, and glycated hemoglobin level. Results Of the 32 patients who presented for TPIAT, 20 underwent L-TPIAT (8 men and 12 women; mean [SD] age, 39 [13] years; age range, 21-58 years). Indication for surgery was CP attributable to genetic mutation (n = 9), idiopathic pancreatitis (n = 6), idiopathic pancreatitis with pancreas divisum (n = 3), and alcohol abuse (n = 2). Mean (SD) operative time was 493 (78) minutes, islet isolation time was 185 (37) minutes, and warm ischemia time was 51 (62) minutes. The mean (SD) IE count was 1325 (1093) IE/kg. The mean (SD) length of stay was 11 (5) days, and the all-cause 30-day readmission rate was 35% (7 of 20 patients). None of the patients experienced postoperative surgical site infection, hernia, or small-bowel obstruction, and none died. Eighteen patients (90%) had a decrease or complete resolution of pain, and 12 patients (60%) no longer required opioid therapy at a median follow-up period of 6 months. Postoperative random insulin C-peptide levels were detectable in 19 patients (95%) at a median follow-up of 10.4 months. At a median follow-up of 12.5 months, 5 patients (25%) were insulin independent, whereas 9 patients (45%) required 1 to 10 U/d, 5 patients (25%) required 11 to 20 U/d, and 1 patient (5%) required greater than 20 U/d of basal insulin. The mean (SD) glycated hemoglobin level was 7.4% (0.5%). Conclusions and Relevance This study represents the first series of L-TPIAT, demonstrating its safety and feasibility. Our approach enables patients to experience shorter operative times and the benefits of laparoscopy, including reduced length of stay and quicker opioid independence.

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
OBJECTIVES Total pancreatectomy with islet autotransplantation is increasingly being performed remotely, that is, removing the pancreas in 1 location, isolating the islet cells in another location, then returning the islets to the original location for reimplantation into the patient. We determined the influence of extended cold ischemia time on key clinical outcomes in remote islet autotransplantation. METHODS We evaluated patients who underwent remote islet autotransplantation at 2 centers from 2011 to 2014. Patients were divided into 2 groups: those with and those without a decrease in C-peptide greater than 50% from baseline. The primary clinical outcome was the quantity of isolated islet equivalents per kilogram body weight (IEQs/kg). RESULTS Twenty-five patients met inclusion criteria; 15 had a decrease in C-peptide greater than 50% from baseline and had lower corresponding IEQs/kg compared with those without a decrease greater than 50% (4045 vs 6654 IEQs/kg, P = 0.01). There was no difference in cold ischemia time between the 2 groups (664 vs 600 minutes, P = 0.25). Daily insulin use at 1 year nearly met statistical significance (25.3 vs 8 U, P = 0.06), as did glycated hemoglobin (8.07 vs 6.69 mmol/L, P = 0.06). CONCLUSIONS Cold ischemia time does not influence islet yield in patients undergoing pancreatectomy with remote isolation.

Abstract
RATIONALE Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. PATIENTS AND METHODS Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien-Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. DIAGNOSIS AND OUTCOMES The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450-540 minutes), the mean estimated blood loss was 266 mL (range 100-400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8-24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. LESSONS Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy.

Abstract
AIM: To evaluate pain control in chronic pancreatitis patients who underwent total pancreatectomy with islet cell transplantation or intrathecal narcotic pump infusion.
METHODS: We recognized 13 patients who underwent intrathecal narcotic pump (ITNP) infusion and 57 patients who underwent total pancreatectomy with autologous islet cell transplantation (TP + ICT) for chronic pancreatitis (CP) pain control between 1998 and 2008 at Indiana University Hospital. All patients had already failed multiple other modalities for pain control and the decision to proceed with either intervention was made at the discretion of the patients and their treating physicians. All patients were evaluated retrospectively using a questionnaire inquiring about their pain control (using a 0-10 pain scale), daily narcotic dose usage, and hospital admission days for pain control before each intervention and during their last follow-up.
RESULTS: All 13 ITNP patients and 30 available TP + ICT patients were evaluated. The mean age was approximately 40 years in both groups. The median duration of pain before intervention was 6 years and 7 years in the ITNP and TP + ICT groups, respectively. The median pain score dropped from 8 to 2.5 (on a scale of 0-10) in both groups on their last follow up. The median daily dose of narcotics also decreased from 393 mg equivalent of morphine sulfate to 8 mg in the ITNP group and from 300 mg to 40 mg in the TP + ICT group. No patient had diabetes mellitus (DM) before either procedure whereas 85% of those who underwent pancreatectomy were insulin dependent on their last evaluation despite ICT.
CONCLUSION: ITNP and TP + ICT are comparable for pain control in patients with CP however with high incidence of DM among those who underwent TP + ICT. Prospective comparative studies and longer follow up are needed to better define treatment outcomes.

Abstract
OBJECTIVE Our objective was to analyze factors predicting outcomes after a total pancreatectomy and islet autotransplantation (TP-IAT). BACKGROUND Chronic pancreatitis (CP) is increasingly treated by a TP-IAT. Postoperative outcomes are generally favorable, but a minority of patients fare poorly. METHODS In our single-centered study, we analyzed the records of 581 patients with CP who underwent a TP-IAT. Endpoints included persistent postoperative "pancreatic pain" similar to preoperative levels, narcotic use for any reason, and islet graft failure at 1 year. RESULTS In our patients, the duration (mean ± SD) of CP before their TP-IAT was 7.1 ± 0.3 years and narcotic usage of 3.3 ± 0.2 years. Pediatric patients had better postoperative outcomes. Among adult patients, the odds of narcotic use at 1 year were increased by previous endoscopic retrograde cholangiopancreatography (ERCP) and stent placement, and a high number of previous stents (>3). Independent risk factors for pancreatic pain at 1 year were pancreas divisum, previous body mass index >30, and a high number of previous stents (>3). The strongest independent risk factor for islet graft failure was a low islet yield-in islet equivalents (IEQ)-per kilogram of body weight. We noted a strong dose-response relationship between the lowest-yield category (<2000 IEQ) and the highest (≥5000 IEQ or more). Islet graft failure was 25-fold more likely in the lowest-yield category. CONCLUSIONS This article represents the largest study of factors predicting outcomes after a TP-IAT. Preoperatively, the patient subgroups we identified warrant further attention.

Abstract
BACKGROUND Total pancreatectomy (TP) with islet autotransplantation (IAT) is a highly selected treatment for severe pain associated with chronic pancreatitis (CP) after exhausting medical and endoscopic therapies. The effect of duration of CP on TP-IAT has not been clarified. METHODS Retrospective review of a consecutive cohort undergoing TP-IAT was performed. Patients were classified according to islet dose of <2500 IEQ/kg, 2500 to 5000 IEQ/kg, and >5000 IEQ/kg. Islet yield and metabolic outcomes were compared to disease duration of CP. RESULTS A total of 76 CP patients underwent TP-IAT. Longer disease duration was associated with lower islet yield transplanted (Spearman's correlation = -0.24; p = 0.04) for total cohort. Highest absolute value of the coefficient was found in patients with hereditary CP when study subjects were classified by the etiology of CP (correlation = -0.72; p = 0.02). Higher islet yields were significantly associated with better metabolic outcomes (7.6 ± 1.1 vs 6.6 ± 1.1% of HbA1c post-TPIAT in patients with <2500 and >5000 IEQ/kg transplanted, respectively; p = 0.04). CONCLUSIONS The duration of CP could affect islet yield and metabolic outcomes. The time since the diagnosis of CP should be considered when selecting patients for islet autotransplantation.

Abstract
Interferon-gamma (IFN-γ) is shown to play a major role in β-cell dysfunction in chronic pancreatitis (CP). However, the underlying mechanisms are to be elucidated. The present study was conducted to determine the role of IFN-γ subverting insulin gene expression in CP. Pancreatic tissues from control (n=15) and CP patients (n=30) were analyzed for nuclear localization of pancreatic and duodenal homeobox transcription factor (Pdx-1) after ascertaining their diabetic status. By immunofluorescence and western blot analysis, the influence of IFN-γ, anti-inflammatory cytokine (interleukin-10), and anti-IFN-γ agent epigallocatechin-3-gallate (EGCG) on nuclear localization of Pdx-1was examined in the islets isolated from resected normal pancreatic tissue. Nuclear localization of Pdx-1 was 20.25±2.19 in the islets of diabetic CP patients and 31.44±2.09 in nondiabetic CP patients as compared with controls (60.45±5.11) and the corresponding distribution of Pdx-1 protein in the nuclear compartment was also decreased. Exposure of normal islets to IFN-γ revealed decreased nuclear localization of Pdx-1. Pretreatment with polyphenolic compound EGCG restored the nuclear localization of Pdx-1. These results suggest that IFN-γ induced β-cell dysfunction is mediated through decreased nuclear localization of Pdx-1.

Abstract
The aim of the study was to assess the rate of insulin independence in patients after total pancreatectomy (TP) and islet autotransplantation in our center. TP followed by islet auto-transplantation was performed in 10 patients. Severe unrelenting pain associated with chronic pancreatitis was the major indication for surgery. Islets were isolated using the modified Ricordi method and infused through the portal vein. Exogenous insulin therapy was implemented for at least two months posttransplant to support islet engraftment and was subsequently weaned off, if possible. Median follow-up was 26 months (range, 2 to 60 months). Median islet yield was 158,860 islet equivalents (IEQ) (range, 40,203 to 330,472 IEQ) with an average islet yield of 2,478 IEQ/g (range, 685 to 6,002 IEQ/g) of processed pancreas. One patient developed transient partial portal vein thrombosis, which resolved without sequela. Five (50%) patients are currently off insulin with excellent glucose control and HbA1c below 6. Patients who achieved and maintained insulin independence were transplanted with significantly more islets (median, 202,291 IEQ; range, 145,000 to 330,474 IEQ) than patients who required insulin support (64,348 IEQ; range, 40,203 to 260,476 IEQ; P < 0.05). Patient body mass index and time of chronic pancreatitis prior transplant procedure did not correlate with the outcome. The remaining five patients, who require insulin support, had present C-peptide in blood and experience good glucose control without incidence of severe hypoglycemic episodes. Islet autotransplantation efficiently preserved beta cell function in selected patients with chronic pancreatitis and the outcome correlated with transplanted islet mass.

Abstract
OBJECTIVES Patients with minimal-change chronic pancreatitis (MCCP) are traditionally managed medically with poor results. This study was conducted to review outcomes following total pancreatectomy with islet cell autotransplantation (TP/IAT) as the initial surgical procedure in the treatment of MCCP. METHODS All patients submitted to TP/IAT for MCCP were identified for inclusion in a single-centre observational study. A retrospective chart review was performed to identify pertinent preoperative, perioperative and postoperative data. RESULTS A total of 84 patients with a mean age of 36.5 years (range: 15-60 years) underwent TP/IAT as the initial treatment for MCCP. The most common aetiology of chronic pancreatitis in this cohort was idiopathic (69.0%, n = 58), followed by aetiologies associated with genetic mutations (16.7%, n = 14), pancreatic divisum (9.5%, n = 8), and alcohol (4.8%, n = 4). The most common genetic mutations pertained to CFTR (n = 9), SPINK1 (n = 3) and PRSS1 (n = 2). Mean ± standard error of the mean preoperative narcotic requirements were 129.3 ± 18.7 morphine-equivalent milligrams (MEQ)/day. Overall, 58.3% (n = 49) of patients achieved narcotic independence and the remaining patients required 59.4 ± 10.6 MEQ/day (P < 0.05). Postoperative insulin independence was achieved by 36.9% (n = 31) of patients. The Short-Form 36-Item Health Survey administered postoperatively demonstrated improvement in all tested quality of life subscales. CONCLUSIONS The present report represents one of the largest series demonstrating the benefits of TP/IAT in the subset of patients with MCCP.

Abstract
The discovery of insulin more than 90 years ago introduced a life-saving treatment for patients with type 1 diabetes, and since then, significant progress has been made in clinical care for all forms of diabetes. However, no method of insulin delivery matches the ability of the human pancreas to reliably and automatically maintain glucose levels within a tight range. Transplantation of human islets or of an intact pancreas can in principle cure diabetes, but this approach is generally reserved for cases with simultaneous transplantation of a kidney, where immunosuppression is already a requirement. Recent advances in cell reprogramming and beta cell differentiation now allow the generation of personalized stem cells, providing an unlimited source of beta cells for research and for developing autologous cell therapies. In this review, we will discuss the utility of stem cell-derived beta cells to investigate the mechanisms of beta cell failure in diabetes, and the challenges to develop beta cell replacement therapies. These challenges include appropriate quality controls of the cells being used, the ability to generate beta cell grafts of stable cellular composition, and in the case of type 1 diabetes, protecting implanted cells from autoimmune destruction without compromising other aspects of the immune system or the functionality of the graft. Such novel treatments will need to match or exceed the relative safety and efficacy of available care for diabetes.

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
Chronic pancreatitis (CP) is a debilitating disease that leads to varying degrees
of pancreatic endocrine and exocrine dysfunction. One of the most difficult
symptoms of CP is severe abdominal pain, which is often challenging to control
with available analgesics and therapies. In the last decade, total
pancreatectomy with autologous islet cell transplantation has emerged as a
promising treatment for the refractory pain of CP and is currently performed at
approximately a dozen centers in the United States. While total pancreatectomy
is not a new procedure, the endocrine function-preserving autologous islet cell
isolation and re-implantation have made the prospect of total pancreatectomy
more acceptable to patients and clinicians. This review will focus on the
current status of total pancreatectomy with autologous islet cell transplant
including patient selection, technical considerations, and outcomes. As the
procedure is performed at an increasing number of centers, this review will
highlight opportunities for quality improvement and outcome optimization.

Abstract
BACKGROUND Selected patients with chronic pancreatitis can benefit from total pancreatectomy with islet autotransplantation. Patient selection is challenging and outcomes assessment is essential. STUDY DESIGN A prospective database of total pancreatectomy with islet autotransplantation patients was reviewed. Attention was given to psychometric assessments, including Short Form-12 Quality of Life Survey (SF-12), Center for Epidemiologic Studies 10-Item Depression scale, and Current Opioid Misuse Measure in the preoperative period, and SF-12 in the postoperative period. RESULTS One hundred and twenty-seven patients (76% women, mean age 40.5 years) underwent total pancreatectomy with islet autotransplantation. Preoperatively, the mean SF-12 physical quality of life score (physQOL) was 27.24 (SD 9.9) and the mean psychological QOL score (psychQOL) was 38.5 (SD 12.8), with a score of 50 representing the mean of a healthy population. Mean improvements in physQOL relative to baseline at 1 year, 2 years, and 3 years post surgery were 7.1, 5.8, and 7.8, respectively, which represented significant change (all p < 0.001). Mean improvements in psychQOL relative to baseline at 1 year, 2 years, and 3 years post surgery were 3.9, 4.9, and 6.6, which also represented significant improvement (all p < 0.001). The percentages of patients evidencing at least a 3-point improvement in physQOL at 1 year, 2 years, and 3 years post surgery were 65%, 60%, and 61%, respectively. The percentages of patients evidencing at least a 3-point improvement in psychQOL at 1 year, 2 years, and 3 years post surgery were 49%, 58%, and 66%, respectively. Exploratory regression analyses of SF-12, Current Opioid Misuse Measure, and Center for Epidemiologic Studies 10-Item Depression scale data revealed limited baseline predictability of surgical response; however, higher opioid misuse scores at baseline were significantly and positively related to physQOL improvement at 2 years (r[54] = 0.33, p = 0.02). CONCLUSIONS Total pancreatectomy with islet autotransplantation improves QOL for selected patients with chronic pancreatitis. The physQOL improves quickly after surgery, and psychQOL improvements are more gradual. Opioid misuse can predict physQOL improvement.

Abstract
Diabetes mellitus, which may cause hyperglycemia and a number of complications, mostly results from a deficiency of β cell mass (type 1 diabetes) or a limitation of β cell function (type 2 diabetes). Currently, enhancing β cell regeneration and increasing cell proliferation have not only been described in experimental diabetes models, but have also been proven to improve outcomes for patients with diabetes. Therefore, understanding the mechanisms controlling the development and regeneration of β cells in the human pancreas may be helpful for the treatment of β cell-deficient disease. In this review, we first introduce the various cell types in the adult pancreas and thereby clarify their functions and origins. Then, the known mechanisms of β cell development and expansion in the normal human pancreas are described. The potential mechanisms of β cell regeneration, including β cell self-replication, neogenesis from non-β cell precursors and transdifferentiation from α cells, are discussed in the next part. Finally, the ability of the pancreas to regenerate mature β cells is explored in pathological conditions, including type 1 diabetes, chronic pancreatitis and persistent hyperinsulinemic hypoglycemia of infancy.

Abstract
OBJECTIVE Total pancreatectomy and islet cell autotransplantation (TPIAT) has been increasingly utilized for the management of chronic pancreatitis (CP) with early success. However, the long-term durability of this operation remains unclear. METHODS All patients undergoing TPIAT for the treatment of CP with 5-year or greater follow-up were identified for inclusion in this single-center observational study. End points included narcotic requirements, glycemic control, islet function, quality of life (QOL), and survival. RESULTS Between 2000 and 2013, 166 patients underwent TPIAT; 112 of these patients had 5-year follow-up data to analyze. All patients underwent successful IAT with a mean of 6027 ± 595 islet equivalents per body weight. There was no perioperative mortality and actuarial survival at 5 years was 94.6%. The narcotic independence rate at 1 year was 55% and continued to improve to 73% at 5-year follow-up (P < 0.05). The insulin independence rate declined over time (38% at 1 year vs 27% at more than 5 years), but insulin requirements remained similar (21.4 vs 24.3 units per day, P = 0.6). All patients achieved stable glycemic control with a median hemoglobin A1C (HgA1C) of 6.9% (range: 5.85%-8.3%). The short form 36-item QOL assessment of a subset of patients available for contact demonstrated continued improvements in all tested modules in patients with at least 5-year follow-up. Two patients developed diabetic complications requiring whole organ pancreas transplant for salvage. CONCLUSIONS This represents one of the largest series examining long-term outcomes after TPIAT. This operation produces durable pain relief and improvement in QOL parameters. Insulin independence rates decline over time, but most patients maintain stable glycemic control.

Abstract
We analyzed the pretransplant continuous glucose monitoring (CGM) data of 45 patients that underwent total pancreatectomy followed by autologous islet transplantation (AIT) at the University of Arizona Medical Center. Traditional and novel metrics of CGM time series were correlated to the total islet count (TIC), islet equivalents (IEQs), and weight-normalized IEQs (IEQ/kg). In a subset cohort (n = 26) we analyzed the relationship among the infused number of islets, the CGM indicators, and the first recorded insulin requirement after the procedure. We conclude that receiving a high islet yield is sufficient yet not necessary to achieve low or null insulin requirements within the first 50 days after surgery. Furthermore, CGM inertia and CGM length of curve (2 novel CGM indicators) are shown to be correlated to islet yield, and the CGMs normalized area (Ao) and time ratio above hyperglycemic level (To) are strongly correlated to insulin requirement. A screening test based on To is shown to have 100% sensitivity and 88% specificity discriminating insulin independence upon discharge.

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
OPINION STATEMENT Chronic pancreatitis is the result of irreversible damage to pancreatic acinar cells, and can result in debilitating chronic pain for patients. Treatment centers on pain relief, often with chronic narcotic use. Surgical therapy consists of both resection procedures to remove affected pancreatic parenchyma and drainage procedures to facilitate drainage of the main pancreatic duct. Total pancreatectomy historically was utilized in extreme cases due to the brittle glucose control that followed from the total loss of islet cells. Total pancreatectomy with islet cell auto-transplantation (TP-AIT) is gaining in popularity due to the maintenance of beta cell mass and the ability of patients to potentially be insulin independent post-operatively. TP-AIT is very helpful in the treatment of pain for patients with chronic pancreatitis. The overall majority of patients have an improvement in pain and quality-of-life scores. AIT also allows the majority of patients to have minimal insulin requirements post-operatively. With proper patient selection, these outcomes can be achieved.

Abstract
BACKGROUND In selected patients, total pancreatectomy with islet autotransplantation (TPIAT) effectively relieves pain caused by chronic pancreatitis and ameliorates the brittle diabetes of the apancreatic state. Patients often undergo multiple endoscopic and surgical interventions prior to TPIAT, increasing the risk for pancreas colonization with enteric microorganisms. Little is known of the safety of transplanting islet cells with microbial contamination. METHODS A prospectively collected database of 80 patients submitted to TPIAT at the Medical University of South Carolina from March 2009 to February 2012 was retrospectively reviewed. Patient charts were reviewed for postoperative infectious complications and organisms identified were compared with those identified in pre-transplant islet cultures. RESULTS A total of 35 patients (43.8%) had a positive pre-transplant islet cell Gram stain or islet cell culture from the final islet preparation solution. Of these 35 patients, 33 (94.3%) were given antibiotics prophylactically post-transplant for a positive islet Gram stain or culture. Twenty patients (57.1%) receiving Gram stain- or culture-positive islets developed postoperative infectious complications, but only four patients (11.4%) developed infections that concorded with their pre-transplant islet product. CONCLUSIONS Islet transplant solutions are frequently culture-positive, presumably as a result of prior pancreas intervention. Microbial contamination of islet preparations should not preclude autotransplantation.

Abstract
BACKGROUND In pancreatitis, total pancreatectomy (TP) is an effective treatment for refractory pain. Islet cell auto-transplantation (IAT) may mitigate resulting endocrinopathy. Short-term morbidity data for TP + IAT and comparisons with TP are limited. METHODS This study, using 2005-2011 National Surgical Quality Improvement Program data, examined patients with pancreatitis or benign neoplasms. Morbidity after TP alone was compared with that after TP + IAT. RESULTS In 126 patients (40%) undergoing TP and 191 (60%) patients undergoing TP + IAT, the most common diagnosis was chronic pancreatitis. Benign neoplasms were present in 46 (14%) patients, six of whom underwent TP + IAT. Patients in the TP + IAT group were younger and had fewer comorbidities than those in the TP group. Despite this, major morbidity was more frequent after TP + IAT than after TP [n = 79 (41%) versus n = 36 (29%); P = 0.020]. Transfusions were more common after TP + IAT [n = 39 (20%) versus n = 9 (7%); P = 0.001], as was longer hospitalization (13 days versus 9 days; P < 0.0001). There was no difference in mortality. CONCLUSIONS This study is the only comparative, multicentre study of TP and TP + IAT. The TP + IAT group experienced higher rates of major morbidity and transfusion, and longer hospitalizations. Better data on the longterm benefits of TP + IAT are needed. In the interim, this study should inform physicians and patients regarding the perioperative risks of TP + IAT.

Abstract
The goal of IAT is the preservation of beta-cell mass at the time of pancreatectomy. The majority of recipients have significant endogenous beta-cell function with positive blood C-peptide after surgery, even if only approximately one third achieve insulin independence. In appropriately selected patients, total pancreatectomy combined with IAT achieves relief of pain and improves quality of life with relatively easier-to-manage glycemic control and avoidance of hyper- and hypoglycemic episodes. Current research is focused on improving techniques of islet isolation and engraftment as well as long-term survival of autografted islets.

Abstract
DESCRIPTION Total pancreatectomy with islet autotransplantation (TPIAT) is a surgical procedure used to treat severe complications of chronic pancreatitis or very high risk of pancreatic cancer while reducing the risk of severe diabetes mellitus. However, clear guidance on indications, contraindications, evaluation, timing, and follow-up are lacking. METHODS A working group reviewed the medical, psychological, and surgical options and supporting literature related to TPIAT for a consensus meeting during PancreasFest. RESULTS Five major areas requiring clinical evaluation and management were addressed: These included: 1) indications for TPIAT; 2) contraindications for TPIAT; 3) optimal timing of the procedure; 4) need for a multi-disciplinary team and the roles of the members; 5) life-long management issues following TPIAP including diabetes monitoring and nutrition evaluation. CONCLUSIONS TPIAT is an effective method of managing the disabling complications of chronic pancreatitis and risk of pancreatic cancer in very high risk patients. Careful evaluation and long-term management of candidate patients by qualified multidisciplinary teams is required. Multiple recommendations for further research were also identified.

Abstract
BACKGROUND This study aims to review surgical outcomes of pediatric patients undergoing total pancreatectomy with islet cell autotransplantation (TP/IAT) for the treatment of chronic pancreatitis (CP). METHODS All pediatric patients (≤18 years old) undergoing TP/IAT over a 10-year period (December 2002-June 2012) were identified for inclusion in a single-center, observational cohort study. Retrospective chart review was performed to identify pertinent preoperative, perioperative, and postoperative data, including narcotic usage, insulin requirements, etiology of pancreatitis, previous operative interventions, operative times, islet cell yields, duration of hospital stay, and overall quality of life. Quality of life was assessed using the Short Form-36 health questionnaire. RESULTS Fourteen pediatric patients underwent TP/IAT for the treatment of CP at the University of Cincinnati with a mean age of 15.9 years (range, 14-18) and a mean body mass index of 21.8 kg/m(2) (range, 14-37). Of the patients, 50% (n = 7) were male and 29% had undergone previous pancreatic operations (1 each of Whipple, Puestow, Frey, and Berne procedures). Etiology of pancreatitis was idiopathic for 57% (n = 8); the remainder had identified genetic mutations predisposing to pancreatitis (CFTR, n = 4; SPINK1, n = 1; PRSS1, n = 1). Mean operative time was 532 minutes (range, 360-674) with an average hospital duration of stay of 16 days (range, 7-37). Islet cell isolation resulted in mean islet cell equivalents (IEQ) of 500,443 in patients without previous pancreatic surgery versus 413,671 IEQ in patients with prior pancreatic surgery (P = .12). Median patient follow-up was 9 months from surgery (range, 1-78). Preoperatively, patients required on average 32.7 morphine equivalent mg per day (MEQ), which improved to 13.9 MEQ at most recent follow-up. Eleven patients (79%) were narcotic independent. None of the patients were diabetic preoperatively. All of the patients were discharged after the operation with scheduled insulin requirements (mean, 17 U/d). This requirement decreased to a mean of 10.1 U/d at most recent follow-up visit. Four patients (29%) progressed to insulin independence. All patients in this series achieved stable glycemic control postoperatively and there was no incidence of "brittle" diabetes. Quality-of-life surveys showed improvement in all tested modules. CONCLUSION This study represents one of the largest series examining TP/IAT in the pediatric population. Pediatric patients benefitted from TP/IAT with a decrease in postoperative narcotic requirements, stable glycemic control, and improved quality of life.

Abstract
The major endpoints for clinical islet transplantation for type 1 diabetes are insulin independence and reduction of hypoglycemic episodes. Both endpoints are influenced by patients' and physicians' preferences regarding the use of exogenous insulin. Therefore, development of an objective endpoint for assessing clinical islet transplantation is desirable. HOMA-beta score is useful in assessing functional β-cell mass. However, this score uses blood insulin levels that are influenced by exogenous insulin injection and therefore is not suitable for patients who receive exogenous insulin. For assessing functional β-cell mass for type 1 diabetic patients after islet transplantation, we created the Secretory Unit of Islet Transplant Objects (SUITO) index using fasting C-peptide and fasting glucose. The formula of the SUITO index is fasting C-peptide (ng/ml)/[fasting blood glucose − 63 (mg/dl)] × 1500. We demonstrated that, within 1 month of islet transplantation, an average SUITO index of >26 was an excellent predictor of achieving insulin independence. In addition, daily SUITO index scores correlated with a reduction of insulin dose and adversely correlated with blood glucose levels during an intravenous glucose tolerance test. Other important endpoints, reduction of hypoglycemic episodes and quality of life, also correlated with the SUITO index. Thus, the SUITO index is excellent for assessing important endpoints (insulin independence, reduction of hypoglycemia, improved quality of life) after allogeneic islet transplantation.

Abstract
BACKGROUND In type 1 diabetics undergoing allogenic islet transplants, transaminitis and portal vein thrombosis (PVT) after transhepatic portal infusion of islets may be related to infusion pressure and the purity of islets. Complications of intraoperative portal infusion of islets in patients with chronic pancreatitis undergoing a total pancreatectomy (TP) and autologous islet transplant (AIT) and the relationship to liver histopathology have not been examined. AIM The purpose of this study was to examine complications of intraportal infusion of autologous islets after TP. METHODS Data on 26 TP-AIT patients were analyzed. RESULTS Infusion of islets [mean 304,473 ± 314,557 islet equivalents, median volume 300 mL (50-600)] resulted in mean postinfusion PV pressure of 9.15 ± 10.09 cmH2O which correlated with infused islets equivalents (r (2) = 33.6, P = 0.002) and volume (r (2) = 30.4, P = 0.005). Of 23 patients undergoing liver biopsy, 8 (35 %) were normal, 10 (43 %) had steatosis, and 5 (22 %) periportal fibrosis. Peak alanine aminotransferase (ALT; median 1 day after infusion) differed among the three histologic groups (P = 0.025). The difference in ALT was statistically significant between steatosis (showed the greatest increase) and the other two groups, but not between the normal and fibrosis groups. No correlation was found between the portal pressure increase at infusion and other variables. Two patients that developed PVT on day 1 had the highest infusion pressures; a third occurred on day 5. CONCLUSION Preexisting liver pathology is a contributing factor in the rise in liver enzymes but does not correlate with development of PV thrombosis.

Abstract
Pancreatic surgery is a complicated procedure leaving postoperative patients with an altered gastrointestinal (GI) anatomy and a potential for further surgical complications such as leaks and fistulas. Beyond surgical complications, these patients are prone to delayed gastric emptying, fat malabsorption, and hyperglycemia, with early satiety and poor appetite further compromising nutrition status. Many of these patients are malnourished prior to this major surgical procedure, and significant weight loss is common postoperatively. Does this affect their outcome? There seems to be a lack of consensus in this patient population regarding how to optimize nutrition and limit potential deleterious effects of this surgery. It is important to first understand the underlying disease condition and the effects to the gland, different forms of surgery with subsequent GI alterations, and common surgical and digestive complications. Once this is reviewed, existing nutrition support literature will be explored in attempts to determine the best nutrition management in this patient population.

Abstract
OBJECTIVE The relationship between magnetic resonance imaging (MRI), histopathology, and islet yield was examined for chronic pancreatitis patients undergoing total pancreatectomy and autologous islet cell transplant (TP-AIT) to determine if the yield can be predicted by pre-operative MRI. METHODS MRI sequences and histopathology were scored and compared for patients from whom ≤2,500 islet equivalents/kg were obtained with those from whom >2,500 islet equivalents/kg were obtained. RESULTS Twenty patients, 14 female, mean age 40.20 ± 12.5 years, (range 19-63) underwent MRI before TP-AIT; mean 3,724 ± 891 islet equivalents/kg body weight, median 2,970, (range 76-17,770) were procured. There was no correlation between islet cell numbers and pancreas weight, HgbA1c, or c-peptide. The most common MRI sequence abnormality was the delayed interstitial phase, 14/18 (78 %). The other common MRI sequence abnormalities were, precontrast T1W 3D GRE sequence, 13/19 (68 %), and the arterial perfusion phase, 11/18 (61 %). The pancreatic duct was dilated in 10/20 (50 %). Parenchymal atrophy was noted in 10/20 (50 %). Median scores for individual MRI sequences were greater in patients with an islet cell yield of ≤2,500 islet equivalents/kg; for the delayed interstitial phase the difference was significant (median 2.5, range 1-3 versus median 0.5, range 0-3, P = 0.034). Histologically the most common feature was fibrosis, (17/17, 100 %); the score for fibrosis was greater for patients with an islet cell yield of ≤2,500 islet equivalents/kg (median 6.0, range 5-7 versus median 4.0, range 3-7, P = 0.024). CONCLUSION A diminished islet yield may be predicted on the basis of the delayed interstitial phase MRI sequence.

Abstract
Total or partial pancreatectomy followed by autologous islet transplantation is a therapeutic option for the treatment of refractory chronic pancreatitis (CP). Maximization of islet yields from fibrotic and inflamed organs is crucial for prevention of posttransplant diabetes. We adapted technical advancements developed for islet allotransplantation toward islet autotransplantation. Eight patients (two men, six women; ages 24-58 years) underwent total (n = 7) or partial (n = 1) pancreatectomy for the treatment of CP refractory to maximal medical management. Pancreata were preserved in UW solution (UW group) in initial three cases and the last five pancreata were preserved with pancreatic ductal injection followed by ET-Kyoto/oxygenated PFC solutions (DI+TLM group). Islets were isolated by modified Ricordi method and were purified only in one case. All islet infusions were performed under general anesthesia via direct vein injection into the portal venous system with pressure monitoring. Total islet yields (129,314 ± 51,627 vs. 572,841 ± 116,934 IEQ, p < 0.04), islet yield/pancreas weight (1,233 ± 359 vs. 6,848 ± 847 IEQ/g, p < 0.003), and islet yield/patient body weight (1,951 ± 762 vs. 7,305 ± 1,531 IEQ/kg, p < 0.05) were significantly higher in the DI+TLM group when compared to the UW group. Pellet size was also higher (5.3 ± 0.3 vs. 13.5 ± 3.4 ml) in the DI+TLM group, suggesting that this method of preservation effectively protected pancreatic tissue against autolysis. First month posttransplant basal C-peptide and the secretory unit of islet transplant objects (SUITO) index were also higher in the DI+TLM group when compared to the UW group (2.0 ± 0.3 vs. 1.4 ± 0.4 ng/ml and 42.6 ± 12.7 vs. 14.6 ± 5.6, respectively). There were no technical complications related to the infusion. Our results suggest that higher islet yields can be achieved even from chronically inflamed and fibrotic organs using DI+TLM. The techniques applied for islet isolations from normal pancreata are showing promise for fibrotic pancreata from CP patients.

Abstract
BACKGROUND Total pancreatectomy (TP) with auto-islet transplant (AIT) is an extreme treatment for chronic pancreatitis, and we reviewed our experience to assess the impact on quality of life (QOL). METHODS A prospective cohort study from 2007 through 2010 with pre- and postoperative assessments of the Depression Anxiety Stress Scale, Pain Disability Index, and visual analogue pain scale was performed. RESULTS Twenty patients underwent TP-AIT with a median follow-up of 12 months (6.75-24 months). All patients reported moderate (45 %) to severe (55 %) pain prior to surgery. TP-AIT resulted in significant decreases in abdominal pain (p < 0.001), 80 % reporting no or mild pain. Despite pain improvement, only 30 % discontinued narcotics. Improvements in all PDI QOL domains improved from 79 to 90 % (p = 0.002), with greatest improvements seen in those without prior pancreatic surgery, younger patients, and in those with higher levels of preoperative pain. Patients were less affected by depression and anxiety prior to surgery, but 60 and 70 % did show improvement in depression and anxiety, respectively (p = 0.033). Sixteen patients (80 %) required exogenous insulin at last follow-up (mean total dose of insulin 11.6 U/day). CONCLUSIONS TP-AIT significantly improves pain and QOL measures in appropriately selected patients with CP.

Abstract
Chronic pancreatitis (CP) is an inflammatory disease characterized by the progressive destruction of pancreatic tissue and resulting in pancreatic exocrine and endocrine insufficiency. Increased oxidative stress has been implicated as a potential mechanism in its etiology and pathology. A number of studies have demonstrated that CP patients have a compromised antioxidant status, which may be a contributing factor to the enhanced oxidative state associated with the disease. Nutrition is an essential consideration in the treatment of CP, especially since diet is a source of several antioxidants and cofactors required for the production of cellular antioxidant enzymes. Many CP patients have an inadequate intake of macro and micronutrients because of abdominal pain and discomfort, which often increase postprandially and discourage eating. Exocrine insufficiency leads to further complications by preventing adequate digestion and absorption of ingested food, thus causing even greater deficiencies and impairment of antioxidant status. The aims of this article are to review the oxidative stress model of CP and to examine the evidence for nutrition, and, particularly, antioxidants, in the treatment of CP.
