Background: Euglycemic diabetic ketoacidosis is a metabolic condition characterized by relative euglycemia, ketonemia, and metabolic acidosis that occurs through mechanisms resembling starvation. Pancreaticoduodenectomy is a complex abdominal operation that subjects patients to a prolonged fasting and an inflammatory state. This study examined the incidence of euglycemic diabetic ketoacidosis and potential opportunities for early diagnosis and management in patients undergoing pancreaticoduodenectomy., Methods: A single-institution retrospective review of 350 patients who underwent pancreaticoduodenectomy between 2017 and 2020 was performed. Primary endpoints were peak beta-hydroxybutyrate levels, peak lactate levels, lowest pH, peak base deficits, and urinary output within the first 24 hours, postoperatively. Additional endpoints included incidence of postoperative pancreatic fistula, delayed gastric emptying, total complications, postoperative hospital length of stay, readmission rates, and changes in insulin regimen at discharge., Results: Of the 350 cases reviewed, 39 (11.1%) patients developed euglycemic diabetic ketoacidosis. Male sex and pancreatic cancer were associated with a risk for euglycemic diabetic ketoacidosis (P < .05). Patients with euglycemic diabetic ketoacidosis had significantly higher peak beta-hydroxybutyrate levels than patients without euglycemic diabetic ketoacidosis (mean difference = 19.8 mg/dL, 95% confidence interval = 14.7-24.9, P < .001), and were nearly four times more likely to require insulin at discharge (odds ratio 3.8, 95% confidence interval = 1.1-13.0, P < .05)., Conclusion: This is the first large descriptive study that investigates euglycemic diabetic ketoacidosis after pancreaticoduodenectomy. Euglycemic diabetic ketoacidosis after pancreaticoduodenectomy is associated with significantly higher beta-hydroxybutyrate levels and new or increased insulin requirement at discharge. Our study demonstrates potential markers for euglycemic diabetic ketoacidosis after pancreaticoduodenectomy, offering an opportunity to identify and successfully treat this disease in a timely manner., (Copyright © 2022 Elsevier Inc.

Background: Type 3c diabetes mellitus (T3cDM) is diabetes secondary to other pancreatic diseases such as chronic pancreatitis, pancreatic resection, cystic fibrosis, and pancreatic ductal adenocarcinoma (PDA). Clinically, it may easily be confused with conventional type 2 diabetes mellitus (T2DM). A delay in pancreatic cancer diagnosis and treatment leads to a worse outcome. Therefore, early recognition of PDA-associated T3cDM and distinction from conventional T2DM represents an opportunity improve survival in patients with PDA., Methods: Six hundred and sixty four patients with PDA underwent pancreatic resection. Patients were classified as per whether or not they had diabetes. The specific type of diabetes was determined. T3cDM surgical patients (n = 127) were compared with a control group of medical patients with T2DM who did not have PDA (n = 127)., Results: Patients with T3cDM were older (66 versus 61 y, P < 0.001), had lower body mass indices (25.9 versus 32.1, P < 0.001), more favorable hemoglobin A1c levels (7.0 versus 8.8, P < 0.001), higher alanine aminotransferase levels (39 versus 20, P < 0.001), and lower creatinine levels (0.8 versus 0.9 mg/dL, P < 0.001). In addition, they were more likely to be insulin dependent. In a subgroup analysis of surgical patients, T3cDM (versus surgical patients with T2DM and no diabetes) was not associated with surrogate markers of main pancreatic duct obstruction and glandular atrophy., Conclusions: PDA-associated T3cDM has a distinctive presenting phenotype compared with medical patients with conventional T2DM. Greater attention to associated signs, symptoms, and biochemical data could identify patients at risk for harboring an underlying pancreatic malignancy and trigger diagnostic pathways leading to earlier PDA diagnosis and treatment., (Copyright © 2020 Elsevier Inc.

Background: While many patients experience prolonged survival after pancreatic resection for benign or malignant disease, the long-term risk of pancreatogenic diabetes mellitus (DM) remains poorly characterized., Methods: One thousand one hundred seven patients underwent pancreatectomy at Thomas Jefferson University between 2006 and 2013. Attempts were made to contact all living patients by telephone and a DM-focused questionnaire was administered., Results: Two hundred fifty-nine of 691 (37 %) surviving patients completed the survey, including 179 pancreaticoduodenectomies (PD), 78 distal pancreatectomies (DP), and 2 total pancreatectomies. In the PD group, 44 (25 %) patients reported having DM prior to resection. Of these, 5 (12 %) had improved glucose control after resection and 21 (48 %) reported escalated DM medication requirements post-resection. Of 135 PD patients without preoperative DM, 24 (18 %) had new-onset DM postoperatively. In the DP group, 23 patients (29 %) had DM preoperatively. None had improved glucose control after resection, while six (26 %) had worse control after resection. Seventeen of 55 DP patients (31 %) without preoperative DM developed new-onset DM postoperatively (p = 0.04 vs. PD). Preoperative HgbA1C >6.0 %, glucose >124 mg/dL, and insulin use >2 units per day were associated with an increased risk of new-onset postoperative DM., Conclusions: The development or worsening of DM after pancreatic resection is extremely common, with different types of resections conveying different risks for disease progression. DP places patients at a greater risk for the development of new-onset postoperative diabetes when compared to PD. In contrast, patients with preoperative diabetes are more likely to experience worsening of their disease after PD as compared to DP. Patients should be screened prospectively, particularly those at highest risk, and informed of and educated about the potential for post-resection DM.

Background: Due to improved surgical outcomes and increased detection of pancreatic lesions, the resection of nonmalignant and indeterminate lesions of the pancreas has increased., Aims: This study aims to assess the outcomes over an extended period of time and the clinical consequences of pancreaticoduodenectomy (PD) performed for nonmalignant indications., Methods: Patients undergoing a PD between 2006 and 2010 were retrospectively identified and asked to complete a symptom survey. Charts were reviewed for hospital admissions, emergency room visits, complications, and procedures performed., Results: A total of 132 patients were identified through database review with a median follow-up of 2.8 years. Forty-two patients (31.1%) completed the phone survey. Pain and diarrhea were the most common symptoms reported, negatively impacting the patient's daily life in 4.9% and 7.3% of patients, respectively. Diabetes developed or worsened in 19.5%, with new insulin required in 12.2%. Complications were rare, with abdominal abscess (7.6%) occurring most commonly., Conclusions: Although some patients experienced symptoms that negatively impacted their daily life or had diabetic issues following surgery, the outcome of patients undergoing PD for nonmalignant indications was generally favorable. Further prospective study is warranted.
