Postoperative Insulin Dose for Cardiac Artery Bypass Graft and Other Cardiac Surgeries in Patients with Type 2 Diabetes: A Retrospective Study.

Recommendations on perioperative glycemic control in cardiac surgery are based on coronary artery bypass graft surgery (CABG), though coronary artery disease and valvular disease are pathologically distinct. We aimed to compare the postoperative insulin requirement between CABG and other cardiac surgeries in type 2 diabetic patients and identify predictive factors for the maximum postoperative insulin dose. We retrospectively included 60 Japanese patients with diabetes/glucose intolerance (HbA1c > 37 mmol/mol [5.6%]) who were hospitalized for cardiovascular surgery between April 2017 and March 2019. We categorized the subjects into the CABG and non-CABG groups, and performed subgroup analysis on patients who received postoperative insulin therapy. The CABG group required a significantly higher insulin dose on postoperative days 2, 5, 6, and 7, and a significantly higher maximum postoperative insulin dose (24.6 U vs 9.7 U, P < 0.001) than the non-CABG group. Multivariate linear regression analyses showed that the independent determinants of the maximum postoperative insulin dose were HbA1c and duration of diabetes in the non-CABG group, and HbA1c in the CABG group. CABG had a higher postoperative insulin requirement than other cardiovascular surgeries; early aggressive insulin therapy is indicated, especially for patients with higher HbA1c levels/longer duration of diabetes.

Long-term outcomes of laparoscopic longitudinal pancreatojejunostomy and modified Frey's procedure for patients of chronic pancreatitis: A 10-year experience.

To mitigate the morbidity associated with open procedures for chronic pancreatitis (CP), there is a paradigm shift towards the laparoscopic approach. However, since these procedures are technically demanding, literature is still limited. We present our experience and long-term outcomes in the management of CP with laparoscopic surgical procedures. This is a retrospective observational study of patients who underwent a laparoscopic surgery for CP between 2009 and 2019. Pain scores using the Visual Analogue Scale (VAS) were compared pre- and postoperatively. In patients with diabetes, the pre- and post-operative insulin requirement was compared. Data of 62 patients were analysed. The mean duration of follow-up was 69 (±22) months. All patients had pain relief post-surgery. The relief of pain was sustained, with the median VAS scores being 1 at 3- and 5-year follow-up. There was a decrease in the median insulin requirement of diabetic patients, which was significant at 3-month and 1-year follow-up ( P < 0.05). Our study demonstrates that laparoscopic surgical procedures offer long-term pain control with low morbidity. Effective ductal decompression may result in a short-term improvement of the endocrine function of the gland.

A Systematic Review of the Effects of Sleeve Gastrectomy and Gastric Bypass on Type 2 Diabetes Control in the Middle East

Objective: The study aimed to explore the outcome of sleeve gastrectomy and gastric bypass in middle east patients with type 2 diabetes through the assessment of the weight trajectory postoperatively and its effect on the glycaemic control assessed by HbA1c. Where applicable, investigate the impact of sleeve gastrectomy and gastric bypass on the reduction of polypharmacy and postoperative Insulin requirements in patients with type 2 diabetes. Research Design and Methods: PubMed and Science Direct databases were searched. The obtained studies were screened for the title and abstract, followed by full-text reading and retrieved relevant studies. The data was extracted from the relevant papers using a united form according to the inclusion criteria. The articles' quality was assessed and critically appraised, and a narrative synthesis was conducted. Results: Eight studies met the inclusion criteria comprised the final review, and all had positive results. Four articles studied sleeve gastrectomy outcomes, and four compared sleeve gastrectomy and gastric bypass. All studies showed weight reduction postoperatively calculated as BMI, Total Weight Loss, or Excess Weight Loss sustained up to 5 years. The studies which assessed glycaemic control showed improvement of glycaemic parameters, reduction of HBA1C, and some achieved remission among prediabetes and diabetes patients. The review also indicated the reduction and cessation of antidiabetic medications following surgical interventions, which is attributed to achieving diabetes remission. A long-term follow-up cohort with a large sample size revealed that HBA1C reduction was more enunciated and sustained following gastric bypass in patients with diabetes. Conclusion: Sleeve Gastrectomy and Gastric Bypass positively affect type 2 diabetes control among obese adult patients in the Middle East. Both surgical interventions lead to weight reduction and improvement of glycaemic parameters postoperatively up to 5 years .........

Immediate Postoperative Insulin Requirements May Predict Metabolic Outcome after Total Pancreatectomy and Islet Autotransplantation.

Chronic pancreatitis (CP) is a progressive disease that leads to eventual loss of endocrine and exocrine function. Total pancreatectomy and islet autotransplantation (TPIAT) is a treatment option for patients with CP; however, predicting postoperative metabolic outcomes remains elusive. In this single-center retrospective study, we report pre-TPIAT characteristics, beta cell function indices, islet yield, and post-TPIAT glucose management data to further understand their relationship. Islet yield, glucose level, and insulin requirement for 72 hours postoperatively were collected for a total of 13 TPIAT recipients between 9-2013 and 9-2018. In addition, their glucose control and basal insulin requirements at 3, 6, and 12 months post-TPIAT were analyzed. All 13 subjects had normal baseline fasting glucose levels. Median islet yield was 4882 IEq/kg (interquartile range 3412 to 8987). Median postoperative total insulin requirement on day 3 was 0.43 units/kg. Pre-TPIAT baseline glucose, insulin, or c-peptide level did not have a significant correlation with the islet yield. Similarly, there was no correlation between islet yield and insulin requirement at 72-hour postoperatively. However, there was an inverse correlation between the absolute islet yield (IEq) and insulin requirement at 6 months and 12 months following post-TPIAT. Further analysis of the relationship between 72-hour post-op insulin requirement and insulin requirement at discharge, 3, 6, and 12 months showed a positive correlation. Despite the finding of inverse correlation of islet yield with long-term basal insulin requirement, this study was not able to detect a correlation between the preoperative parameters to postoperative short-term or long-term outcome as noted in other studies. The 72-hour postoperative insulin requirement is a helpful postoperative predictor of patients needing long-term insulin management following TPIAT. This observation may identify a high-risk group of patients in need of more intensive diabetes education and insulin treatment prior to hospital discharge.

Imaging prediction of islet yield and post-operative insulin requirement in children undergoing total pancreatectomy with islet autotransplantation

BackgroundPredicting post-operative glycemic control in children undergoing total pancreatectomy with islet autotransplantation (TPIAT) remains difficult. The purpose of our study was to explore preoperative imaging as a marker for islet yield and insulin need in pediatric patients undergoing TPIAT. MethodsThis was a retrospective study of children (≤18 years) who had undergone TPIAT between April 2015 and December 2018 and had 6 or more months of post-TPIAT follow-up. Patient specific factors (height, weight, body mass index [BMI], body surface area [BSA]) and pancreas volume segmented from the most recent pre-operative cross-sectional imaging were explored as predictors of islet yield (total islet counts [TIC], total islet equivalents [TIE], islet equivalents per kilogram body weight [IEQ/kg]) and glycemic control (total daily dose of insulin per kilogram body weight [TDD/kg], insulin independence) using Pearson correlation and univariate and multiple regression. ResultsThirty-three patients, median age 13 years (IQR: 10–15 years), 64% female (21/33) met inclusion criteria. Nine patients (27%) achieved insulin independence at six months. Median TIE isolated was 310,000 (IQR: 200,000–460,000). Segmented pancreas volume was moderately associated with TIE (coefficient estimate = 0.34, p = 0.034). On multiple regression analysis, there was no significant predictor of insulin independence but number of attacks of pancreatitis (estimate = 0.024; p = 0.018) and segmented pancreas volume by body weight (estimate = −0.71; p < 0.001) were significant predictors of insulin TDD/kg. ConclusionPancreas volume segmented from pre-TPIAT imaging has predictive performance for post-TPIAT insulin need in children.

The Effect of Preoperative Carbohydrate Loading on Clinical and Biochemical Outcomes after Cardiac Surgery: A Systematic Review and Meta-Analysis of Randomized Trials.

Background and aim: Preoperative fasting leads to metabolic stress and causes insulin resistance in patients undergoing cardiac surgery. The aim of this study was to assess the effect of preoperative oral carbohydrate loading (OCH) on outcome in patients undergoing planned cardiac surgery by systematically reviewing the literature and synthesizing evidence from randomized controlled trials (RCTs). Methods: Systematic search of PubMed/MEDLINE/Embase/Cinahl/Web of Science/ClinicalTrials databases was performed to identify relevant RCTs from databased inception until 05/03/2020. We included studies that compared outcome measures between OCH with control (placebo or standard starvation). We conducted a random-effect meta-analysis of clinical and biochemical parameters. Results: Nine studies (N = 9) were included with a total of 507 patients. OCH significantly decreased aortic clamping duration (n = 151, standardized mean difference (SMD) = −0.28, 95% confidence interval (CI) = −0.521 to −0.038, p = 0.023 and differences in means (DM) = −6.388, 95%CI = −11.246 to −1.529, p = 0.010). Patients from treatment groups had shorter intensive care unit (ICU) stay (n = 202, SMD = −0.542, 95%CI = −0.789 to −0.295, p < 0.001 and DM = −25.925, 95%CI = −44.568 to −7.283, p = 0.006) and required fewer units of insulin postoperatively (n = 85, SMD = −0.349, 95%CI = −0.653 to −0.044, p = 0.025 and DM = −4.523, 95%CI = −8.417 to −0.630, p = 0.023). The necessity to use inotropic drugs was significantly lower in the OCH group (risk ratio (RR) = 0.795, 95%CI = 0.689 to 0.919, p = 0.002). All other primary outcomes did not reveal a significant effect. Conclusions: Preoperative OCH in patients undergoing cardiac surgery demonstrated a 20% reduction in the use of inotropic drugs, a 50% reduction of the length of ICU stay, a 28% decrease in aortic clamping duration and a 35% decrease of postoperative insulin requirement.

OR26-04 Immediate Post-Operative Insulin Requirements May Predict Metabolic Outcome After Total Pancreatectomy and Islet Autologous Cell Transplant (TPIAT)

Immediate Post-Operative Insulin Requirements may Predict Metabolic Outcome after Total Pancreatectomy and Islet Autologous Cell Transplant (TPIAT) Introduction: Chronic pancreatitis (CP) is a progressive disease that leads to eventual loss of endocrine and exocrine function. Patients with CP experience abdominal pain, which in some instances can be refractory to medical and endoscopic intervention. Total pancreatectomy and islet auto transplantation (TPIAT) is a treatment option however predicting postoperative metabolic outcomes remains elusive. In this single-center retrospective study, we report pre-TPIAT characteristics, beta cell function indices, islet yield as well as post-TPIAT glucose management data to further understand their relationship.Methods:A total of 13 TPIAT subjects were included who underwent beta cell function assessment via intravenous glucose tolerance tests and oral mixed meal tolerance tests. Islet yield, glucose level and insulin requirement for 72 hours postoperatively were collected. In addition, their glucose control and insulin requirements at 3, 6 and 12-month post TPIAT were analyzed.Results:The median age was 45 years with median duration of CP for 5 years. The main cause of CP was idiopathic. All 13 subjects had normal baseline fasting glucose levels. Median islet yield was 4882 IEq/kg (interquartile range 3412 to 8987). Median post-operative total insulin requirement on day 3 was 0.43 units/kg. Pre-TPIAT baseline glucose, insulin or c-peptide level did not have a significant correlation with the islet yield. Similarly, there was no correlation between islet yield and insulin requirement at 72-hour post operatively. However, there was an inverse correlation between the absolute islet yield (IEq) and insulin requirement at 6 months and 12 months following post-TPIAT. Further analysis of the relationship between 72-hour post-op insulin requirement and insulin requirement at discharge, 3, 6 and 12 month showed a positive correlation. Despite the new finding of inverse correlation of islet yield with long-term insulin requirement, this study was not able to detect a correlation between the preoperative parameters to postoperative short-term or long-term outcome as noted in other studies.Conclusion: The 72-hour postoperative insulin requirement is a helpful postoperative predictor of patients needing long term insulin management following TPIAT. This observation may identify a high risk group of patients in need of more intensive diabetes education and treatment prior to hospital discharge.

Longitudinal Islet Function And Insulin Requirement After Total Pancreatectomy With Islet Autotransplantation

Presenter: William Lancaster MD | Medical University of South Carolina Background: Total pancreatectomy with islet autotransplantation is treatment for chronic pancreatitis. Though a significant proportion of patients do not require insulin postoperatively, evidence suggests that insulin independence declines over time. The objective of this study is to measure long term islet function and insulin independence after TPIAT. Methods: A retrospective analysis of a prospectively maintained database of patients undergoing TPIAT was conducted. Postoperative islet function was measured with serum C peptide levels. Postoperative insulin requirements and hemoglobin A1C values were tabulated. Results: A total of 190 patients were included. The mean islet transplant dose was 3545 IEq/kg. The mean serum C-peptide level was constant at 1.1 ng/mL at 6 months, 1 year, and 2 years postoperative. This decreased significantly to 0.5 ng/mL (p<0.05) at 3 years postoperative and remained at this level at 5 years postoperative. The rate of insulin independence was 32% and 30% at 1 and 2 years postoperative, respectively. Insulin independence declined at 3 years postoperative to 23% (p<0.05) and 20% at 5 years postoperative. The mean insulin requirement (units/day) was 26, 25, and 28 at 1, 3, and 5 years postoperative, respectively. Mean postoperative hemoglobin A1C values at 1, 3, and 5 years postoperative were 8.0, 8.2, and 7.8. Conclusion: Islet function declines over time after TPIAT with a corresponding decline in insulin independence rates at 3 years postoperative. In spite of this, glycemic control remains stable. Further study is needed to understand the decline in islet function over time and to develop preventive strategies.

Effective reduction in stress induced postoperative hyperglycemia in bariatric surgery by better carb loading

BackgroundPreoperative carbohydrate loading is a recommended component of enhanced recovery protocols (ERP’s), however the impact on postoperative stress-induced insulin resistance remains poorly studied in both diabetics and non-diabetics. MethodsUsing our ERP, a preoperative grape juice group (Grape) was compared to the use of 25 g maltodextrin/3 g citrulline (G.E.D.™, SOF Health, LLC) for carbohydrate loading. ResultsThe population included 171 patients (Grape n = 96; GED n = 75). Glycemic variability was significantly worse for the Grape group on POD 0 in both non-diabetic (70% vs 41%; p < 0.05) and diabetic patients (66% vs 34%; p < 0.05). Significantly more Grape patients required postoperative insulin regardless of diabetic status. ConclusionFollowing bariatric surgery, the impact of stress induced hyperglycemia is primarily on POD 0 in non-diabetics whereas the effect extends into POD 1 for diabetics. Preoperative loading with G.E.D.™ versus grape juice is associated with a significantly lower rate of glycemic variation and postoperative insulin requirement, demonstrating that drink composition and treatment process reduces the severity of postoperative stress induced hyperglycemia in bariatric surgery patients.

The Effect of Dexamethasone on Postoperative Blood Glucose in Patients With Type 2 Diabetes Mellitus Undergoing Total Joint Arthroplasty

BackgroundPerioperative glucocorticoids are routinely administered to patients undergoing total joint arthroplasty (TJA) to decrease postoperative pain and nausea. However, there is concern regarding the effects of glucocorticoids on perioperative glucose control in diabetes. The goal of this study is to determine if administration of preoperative dexamethasone to diabetic patients is significantly associated with hyperglycemia and increased insulin requirements in the immediate postoperative period after TJA and to identify risk factors for postoperative hyperglycemia immediately after TJA. MethodsA retrospective review of type 2 diabetic patients undergoing TJA from 2010 to 2015 (n = 285) was undertaken to evaluate the effect of dexamethasone on postoperative glucose control. Preoperative baseline characteristics were compared between patients who did and did not receive 8 mg of intravenous dexamethasone preoperatively. Postoperative glucose and insulin requirements were evaluated with respect to dexamethasone dosing. Statistical analysis was performed using logistic regression models. ResultsDexamethasone administration did not correlate with the maximum postoperative blood glucose (P = .78). There was a significantly higher initial postoperative blood glucose after intravenous dexamethasone administration (P < .01). Dexamethasone administration was associated with increased aspart insulin requirements on postoperative day 0 (P = .04). However, preoperative hemoglobin A1c was most strongly associated with postoperative glucose control. ConclusionPreoperative dexamethasone administration to diabetic patients was associated with an initial increase in blood glucose and increased insulin requirement on postoperative day 0. Yet the observed effect on glucose control in diabetic patients may not outweigh the known clinical benefits of perioperative glucocorticoids.

Effects of Intraoperative Dexamethasone Administration in Adult Diabetic Burn Patients.

The steroid dexamethasone is used intraoperatively to prevent postoperative nausea. Studies of intraoperative steroid use in diabetic patients have shown conflicting effects on blood glucose and complications, and their use has not yet been studied in the burn population. A review of adult diabetic acute burn patients undergoing surgery at a verified burn center from 2012 to 2017 was conducted. Statistical analysis compared those who did and did not receive an intraoperative steroid. A total of 74 patients who underwent 121 operations were identified; steroid was administered in 14.0% of cases. There were no statistically significant differences in preoperative glucose, insulin requirements, TBSA, or hemoglobin A1C. Postoperatively, the steroid group had a 16.7 mg/dl (SD = 11.1) increase in blood glucose (P = .042) and 53.5 unit/24 hour (SD = 28.4) increase in insulin requirement (P = .019), compared with no change in controls. The complication rate in the steroid group was 52.9% compared with 20.1% in controls (P = .003); partial graft loss was the most common complication. Diabetic burn patients who receive intraoperative steroid have increased postoperative blood glucose levels, insulin requirements, and complication rates compared with patients who do not receive steroids. Discussion is warranted to avoid intraoperative steroid in this population.

The Impact of Endoscopic Retrograde Cholangiopancreatography on Islet Cell Yield During Total Pancreatectomy With Islet Autotransplantation.

Many patients with recurrent acute and chronic pancreatitis who are candidates for total pancreatectomy and islet cell autotransplantation (TPIAT) undergo endoscopic retrograde cholangiopancreatography (ERCP). However, little is known on the impact of ERCP on TPIAT outcomes. We aimed to explore the effect of antecedent ERCP on islet yield and postoperative insulin requirement after TPIAT. Through a prospectively maintained database, we identified patients who underwent TPIAT at our institution between 2009 and 2016. After adjusting for confounders, islet cell yield and postoperative insulin requirement were compared between subjects who did and did not undergo ERCP within 2 years prior to TPIAT. Data were available on 167 TPIAT patients during the study period; 105 (62.9%) had undergone ERCP within 2 years prior. Prior ERCP was not associated with a reduction in islet equivalents per patient kilogram (odds ratio, 1.37; 95% confidence interval, 0.75-2.5; P = 0.31). Antecedent ERCP was not associated with increased postoperative insulin requirement among patients with no diabetes undergoing TPIAT (odds ratio, 0.85; 95% confidence interval, 0.39-1.83; P = 0.67). Antecedent ERCP does not appear to have a deleterious impact on islet cell yield during TPIAT. Additional multicenter data are needed to more clearly determine the impact of ERCP in this context.

Postoperative Insulin Requirements in Bariatric Surgery

Though insulin dose reduction months after surgery is a well-studied outcome, there are limited data on immediate postoperative changes. The goals of the present study were to ( 1) To determine peri-operative glycemic control in patients with type 2 diabetes mellitus (DM) on insulin who have undergone Roux-en-Y gastric bypass (RYGB) and ( 2) to compare pre- and postoperative insulin regimens and dosages in these patients. A retrospective chart review was conducted on patients with type 2 DM on insulin who underwent RYGB surgery. Blood glucose (BG) levels and insulin doses were compared prior to surgery, on the day of surgery (DOS), and postoperative days (POD) 1 and 2. Subgroup analysis was performed to see if insulin dose was related to glucose control. There were 114 subjects with a mean (SD) age of 52.8 ± 9.8 years, body mass index (BMI) 46.2 ± 8.0 kg/m2, glycated hemoglobin A1c (HbA1c) 8.3% (67 mmol/mol) ± 1.7%, and 66% on insulin plus noninsulin medications and 34% on insulin only. Mean blood glucose (BG) significantly decreased from the DOS (185 ± 43 mg/dL) through POD2 (160 ± 36, P<.0001). The median daily insulin dose significantly decreased from before surgery on usual diet (75 units [36, 116 interquartile range (IQR)]) through POD2 (6 [2, 15 IQR]), P<.0001). The median insulin dose per body weight decreased significantly from before surgery on usual diet (0.58 units/kg [0.35, 0.84 IQR]) through POD2 (0.04 [0.02, 0.11 IQR]), P<.0001). The subgroup with relatively good control experienced a larger percentage reduction in insulin requirements versus subjects with poor control. An 87.5% reduction in total daily insulin dose was seen by POD2. This will assist in developing algorithms for insulin titration postbariatric surgery. BG = blood glucose DM = diabetes mellitus DOS = day of surgery HbA1c = glycated hemoglobin IQR = interquartile range IV = intravenous NPH = neutral protamine Hagedorn POD = postoperative day RYGB = Roux-en-Y gastric bypass SSRI = sliding scale regular insulin.

Do preoperative oral carbohydrates improve postoperative outcomesin patients undergoing coronary artery bypass grafts?

Background/aim: The aim of this prospective study was to determine whether the preoperative oral intake of carbohydrate-rich drinks by patients undergoing a coronary artery bypass graft attenuates postoperative insulin requirements, improves postoperative patient discomfort, provides inotropic support, shortens the length of the ICU stay, and shortens the duration of postoperative mechanical ventilation. Materials and methods: This randomized prospective clinical study included 152 patients with coronary artery disease who were divided into 4 groups. Carbohydrates were administered to 3 groups at different hours and doses before operation. The fourth group had an 8-h preoperative fasting period. The inotropic and vasopressor requirements, ventilation time, and ICU stay time were recorded for all of the groups. Patient wellbeing, mouth dryness, hunger, anxiety, and nausea were assessed using VAS scores of 1-10. Results: Mouth dryness and hunger were significantly higher in the control group (P = 0.03, P = 0.02). The increase in blood glucose level was significantly higher in the control group (P = 0.04). The exogenous insulin requirement was significantly higher in the control group than in the other groups (P = 0.04). Conclusion: The administration of carbohydrates before elective cardiac surgery reduced insulin resistance. Based on the VAS scores, the intake of carbohydrates reduced mouth dryness and hunger. Overall, preoperative oral carbohydrate treatments can improve the postoperative outcomes of coronary artery bypass graft surgeries.

Abstract #293: Post-Operative Insulin Requirements in Bariatric Surgery

A Role for Transplant Endocrinologists - It's About Time

Since the introduction of clinical pancreas transplantation as a treatment for type 1 diabetes in the United States in the 1980s, endocrinologists, save the few conducting mechanistic investigations into the consequences of restoring endocrine function on metabolism and the complications of diabetes ( 1. Morel P. Goetz F.C. Moudry-Munns K. Freier E. Sutherland D.E. Long-term glucose control in patients with pancreatic transplants. Ann Intern Med. 1991; 115: 694-699 Crossref PubMed Scopus (66) Google Scholar ), have been largely uninvolved in the evaluation for or subsequent care and monitoring of pancreas transplant recipients. Historically, this may have been appropriate, since a pancreas transplant is usually added to a kidney transplant for a type 1 diabetic patient with end-stage nephropathy. Moreover, as kidney transplantation was established first, referral to a transplant center with medical determination for the indication of adding a pancreas and monitoring its function was handled by the transplant nephrologist. Finally, because the benefits of near-normal glycemic control in type 1 diabetes were not yet appreciated, success of a pancreas transplant was measured only by the postoperative insulin requirement, with a return to insulin therapy indicating graft failure.

Extended distal pancreatectomy for advanced pancreatic neck cancer.

Backgrounds/AimsWe investigated the clinical application of extended distal pancreatectomy in patients with pancreatic neck cancer accompanied by distal pancreatic atrophy. In this study, we have emphasized on the technical aspects of using the linear stapling device for a bulky target organ.MethodsFrom March 2010 to September 2013, 46 patients with pancreatic adenocarcinoma, who underwent pancreatic resection with radical intent at our institute, were reviewed retrospectively. Among them, three patients (6.5%) underwent extended distal pancreatectomy. A linear stapling device and vise-grip locking pliers were used for en bloc resection of the distal pancreas, first duodenal portion, and distal common bile duct. The results were compared with those after standard pancreatectomy.ResultsAll three patients presented with jaundice, and the ratio of pancreatic duct to parenchymal thickness of the pancreatic body was greater than 0.5. Grade A pancreatic fistula developed in all of the cases, but none of these fistulae were lethal. Pathological staging was T3N1M0 in all of the patients. The postoperative daily serum glucose fluctuations and insulin requirements were comparable to those in patients who received pancreaticoduodenectomy or distal pancreatectomy. At the last follow-up, two patients were alive with liver metastasis at 4 and 10 months postoperatively, respectively, and one patient died of liver metastasis at 5 months postoperatively.ConclusionsWhile the prognosis of advanced pancreatic neck adenocarcinoma is still dismal, extended distal pancreatectomy is a valid treatment option, especially when there is atrophy of the distal pancreas. Also, the procedure is technically feasible, and further refinement is necessary to improve patient survival.

Increase in Postoperative Insulin Requirements Does Not Lead to Decreased Quality of Life after Total Pancreatectomy with Islet Cell Autotransplantation for Chronic Pancreatitis

Previous studies have shown that total pancreatectomy with islet cell autotransplantation improves quality of life in chronic pancreatitis. A significant number of these patients develop postoperative hyperglycemia and daily insulin requirements or increase in daily insulin requirements. Our study investigates whether increased insulin requirements postoperatively have a negative impact on quality of life. A prospectively collected database of 74 patients undergoing extensive pancreatectomy with islet autotransplantation for pancreatitis was reviewed. Data pertaining to daily requirements and quality of life (QOL), as measured by the SF-12 questionnaire, in the preoperative and postoperative period were reviewed. Approval from the Institutional Review Board for the evaluation of human subjects was obtained. Seventy-four patients underwent extensive pancreatectomy with islet autotransplantation for pancreatitis. The majority of these patients required new daily insulin or an increase in daily insulin requirements postoperatively. Mean preoperative HA1c in this group was 5.6 with an increase to 7.3 at 6 months postoperatively (P < 0.001), a mean of 8.1 at 12 months, and 8.9 at 2 years. Mean preoperative daily insulin requirements for this group were five units/day with average increase to 19 units/day at 6 months, 21 units/day at 12 months, and 26 units/day at 2 years. Preoperative QOL scores were a mean of 26 for the physical component and 36 for the mental health component. Postoperatively, physical component scores averaged 33 at 6 months (p < 0.001), 36 at 12 months, and 36 at 2 years; the mental health component scores averaged 42 at 6 months (p = 0.007), 41 at 12 months, and 41 at 2 years. There is no correlation between physical component score or mental component score QOL scores and daily insulin requirements (r = -0.016 and r = 0.039, respectively). Total pancreatectomy with islet cell autotransplantation is an effective surgery for end-stage chronic pancreatitis. Quality of life significantly improves in physical and mental health components regardless of a postoperative increase in daily insulin requirements.

Preoperative oral supplementation with carbohydrate and branched-chain amino acid-enriched nutrient improves insulin resistance in patients undergoing a hepatectomy: a randomized clinical trial using an artificial pancreas

Glucose metabolism is adversely affected in patients following major surgery. Patients may develop hyperglycemia due to a combination of surgical stress and postoperative insulin resistance. A randomized trial was conducted to elucidate the effect of preoperative supplementation with carbohydrates and branched-chain amino acids on postoperative insulin resistance in patients undergoing hepatic resection. A total of 26 patients undergoing a hepatectomy for the treatment of a hepatic neoplasm were randomly assigned to receive a preoperative supplement of carbohydrate and branched-chain amino acid-enriched nutrient mixture or not. The postoperative blood glucose level and the total insulin requirement for normoglycemic control during the 16 h following hepatic resection were determined using the artificial pancreas STG-22. Postoperative insulin requirements for normoglycemic control in the group with preoperative nutritional support was significantly lower than that in the control group (P = 0.039). There was no incidence of hypoglycemia (<40 mg/dL) observed in patients, including those with diabetes mellitus, when the STG-22 was used to control blood glucose levels. STG-22 is a safe and reliable tool to control postoperative glucose metabolism and evaluate insulin resistance. The preoperative oral administration of carbohydrate and branched-chain amino acid-enriched nutrient is of clinical benefit and reduces postoperative insulin resistance in patients undergoing hepatic resection.

Levosimendan or Milrinone in the Type 2 Diabetic Patient With Low Ejection Fraction Undergoing Elective Coronary Artery Surgery

The purpose of this study was to compare the hemodynamic profiles and the postoperative insulin requirements in 2 groups of type 2 diabetic patients with depressed myocardial function who underwent elective surgery for coronary artery disease and who received levosimendan or milrinone for postcardiopulmonary bypass low-output syndrome. Randomized controlled trial. The Chest Diseases Hospital, Safat, Kuwait. Type 2 diabetic patients undergoing elective surgery for coronary artery disease. Fourteen patients and 16 patients received levosimendan and milrinone infusions, respectively, for treatment of the low-output syndrome. The hemodynamic, mixed venous oxygen saturation, oxygen extraction ratios, arterial lactate concentrations, and postoperative insulin infusion rates were serially documented for the first 48 hours after the diagnosis. The cardiac index and mixed venous oxygen saturation were significantly higher in the levosimendan group. The pulmonary capillary wedge pressure, systemic vascular resistance, and oxygen extraction ratios were significantly higher in the milrinone treatment group. The insulin requirements were similar for both of the treatment groups. Levosimendan was more efficient than milrinone for treating the hemodynamic manifestations of the postcardiopulmonary bypass low-output syndrome. However, all the values in the milrinone treatment group were normalized. In this small population, both treatment groups had similar postoperative insulin requirements.
