Long-term resolution of type 2 diabetes after biliopancreatic diversion and duodenal switch procedure: a retrospective analysis from a high-volume institution.

BACKGROUND: Biliopancreatic diversion with duodenal switch (BPD-DS) has been shown to result in better weight loss than other bariatric procedures. Very limited data are available, especially long term, in terms of the resolution of diabetes. OBJECTIVE: The objective of this study was to evaluate the long-term resolution (>5 years) of type 2 diabetes after BPD-DS. SETTING: Academic hospital. METHODS: This is a retrospective chart review of patients with diabetes who underwent primary BPD-DS at our institution from 2010 to 2015. Data for that cohort were collected until January 2021. RESULTS: A total of 151 patients who had met the criteria were included in the final analysis. More than 1 year of follow-up data was available for 94% of patients, and more than 5 years of follow-up data was available for 51%. Most of the patients (98.1%) had either partial or complete resolution or improvement. CONCLUSION: Patients with type 2 diabetes who underwent BPD-DS had profound improvement of their diabetes postoperatively. A significant percentage experienced complete resolution, with most of the remaining patients having demonstrated much improvement in their condition.

Decision Making Regarding Trauma Patients in Rhode Island who Present on Anticoagulants and Antiplatelet Agents: A Multidisciplinary and Collaborative Approach.

OBJECTIVES: Use of anticoagulant and antiplatelet medications (AAMs) is increasing significantly with our growing population of older adults. AAMs worsen outcomes in trauma patients. Our goal was to improve collaboration between trauma and outpatient providers and to improve safety in making decisions on anticoagulant and antiplatelet medications(AAMs) after injuries. DESIGN: A risk management initiative. SETTING AND PARTICIPANTS: Patients that suffered traumatic injury while on anticoagulation or antiplatelets medications at a level I university trauma center. METHODS: IRB approval was obtained to review records for medications, demographics, mechanism and type of injury, and indication for preinjury AAM use. Inpatient trauma team providers contacted the primary prescriber. A collaborative decision was made regarding AAM plans. RESULTS: One hundred and five patients, mean age 79 years, were followed. The three most common AAMs were warfarin (69 patients), clopidogrel (24), and Factor Xa inhibitors (16). Atrial fibrillation was the most common indication for AAMs (70 patients), venous thrombosis (14) and TIA/CVA (11). Falls were the most frequent injury mechanism, 79.4%. Soft tissue hematomas (27.4%), TBI (16%), and pelvic fractures (12.3%) were the most common injuries. In 56.6% AAMs were held until follow-up, 31.1% had AAMs resumed at discharge, and AAMs were held indefinitely in 12.3%. Patients discharged to home versus facility (37 vs 18% p<0.05), <75 years of age (47 vs 27% p<0.05) were more likely to have AAMs resumed at discharge. Patients who suffered falls versus MVC mechanism were less likely to have AAMs resumed at discharge (28 vs 82% p<0.05). CHA2DS2-VASc scores were similar between decision groups. CONCLUSIONS AND IMPLICATIONS: This is the first description of mandatory communication between trauma and outpatient providers to guide decision making on AAMs after injury. Efforts should be made to determine if this mitigates risk by following patients longterm. This communication should become standard for a population that is often elderly, frail, and at risk of repeat injuries.

Factor VIII elevation may contribute to portomesenteric vein thrombosis after laparoscopic sleeve gastrectomy: a multicenter review of 40 patients.

BACKGROUND: Portomesenteric vein thrombosis (PMVT) has been increasingly reported after laparoscopic sleeve gastrectomy (LSG). Factor VIII (FVIII) is a plasma sialoglycoprotein that plays an essential role in hemostasis. There is increasing evidence that FVIII elevation constitutes a clinically important risk factor for venous thrombosis. OBJECTIVES: To report the prevalence of FVIII elevation as well as other clinical characteristics in a multicenter series of patients who developed PMVT after LSG. SETTING: University hospitals. METHODS: A retrospective review was conducted of all patients that developed PMVT after laparoscopic bariatric surgery from 2006 to 2016 at 6 high-volume bariatric surgery centers. RESULTS: Forty patients who developed PMVT postoperatively, all after LSG, were identified. During this timeframe, 25,569 laparoscopic bariatric surgery cases were performed, including 9749 LSG (PMVT incidence after LSG = .4%). Mean age and body mass index were 40 years (18-65) and 43.4 kg/m2 (35-59.7), respectively. Abdominal pain was the most common (98%) presenting symptom. Of patients, 92% had a hematologic abnormality identified, and of these, FVIII elevation was the most common (76%). The vast majority (90%) was successfully managed with therapeutic anticoagulation alone. A smaller number of patients required small bowel resection (n = 2) and surgical thrombectomy (n = 1). There were no mortalities. CONCLUSIONS: A high index of clinical suspicion and prompt diagnosis/treatment of PMVT usually leads to favorable outcomes. FVIII elevation was the most common (76%) hematologic abnormality identified in this patient cohort. Further studies are needed to determine the prevalence of FVIII elevation in patients seeking bariatric surgery.

Stomach Intestinal Pylorus Sparing (SIPS) Surgery for Morbid Obesity: Retrospective Analyses of Our Preliminary Experience.

BACKGROUND: Although the duodenal switch (DS) has been the most effective weight loss surgical procedure, it is a small minority of the total bariatric surgical cases performed. Modifications that can make the operation technically simpler and reduce a long-term risk of short bowel syndrome would be of benefit. The aim of this study was to detail our initial experience with a modified DS called stomach intestinal pylorus sparing (SIPS) procedure. METHODS: Data from patients who underwent a primary SIPS procedure performed by two surgeons at two centers from January 2013 to August 2014 were retrospectively analyzed. All revisions of prior bariatric procedures were excluded. Regression analyses were performed for all follow-up weight loss data. RESULTS: One hundred twenty-three patients were available. One hundred two patients were beyond 1 year postoperative, with data available for 64 (62 % followed up). The mean body mass index (BMI) was 49.4 kg/m(2). Two patients had diarrhea (1.6 %), four had abdominal hematoma (3.2 %), and one had a stricture (0.8 %) in the gastric sleeve. Two patients (1.6 %) were readmitted within 30 days. One patient (0.8 %) was reoperated due to an early postoperative ulcer. At 1 year, patients had an average change in BMI of 19 units (kg/m(2)), which was compared to an average of 38 % of total weight loss or 72 % of excess weight loss. CONCLUSIONS: Modification of the classic DS to one with a single anastomosis and a longer common channel had effective weight loss results. Morbidity seems comparable to other stapling reconstructive procedures. Future analyses are needed to determine whether a SIPS procedure reduces the risk of future small bowel obstructions and micronutrient deficiencies.

Can Composite Nutritional Supplement Based on the Current Guidelines Prevent Vitamin and Mineral Deficiency After Weight Loss Surgery?

BACKGROUND: Nutritional deficiencies occur after weight loss surgery. Despite knowledge of nutritional risk, there is little uniformity of postoperative vitamin and mineral supplementation. The objective of this study was to evaluate a composite supplement based on the clinical practice guidelines proposed in 2008 regarding vitamin and mineral supplementation after Roux-en-Y gastric bypass. The composite included iron (Fe) and calcium as well. METHODS: A retrospective chart review of 309 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) was evaluated for the development of deficiencies in iron and vitamins A, B1, B12, and D. Patients were instructed to take a custom vitamin and mineral supplement that was based on society-approved guidelines. The clinical practice guidelines were modified to include 1600 international units (IU) of vitamin D3 instead of the recommended 800 IU. RESULTS: The compliant patients' deficiency rates were significantly lower than those of the noncompliant patients for iron (p = 0.001), vitamin A (p = 0.01), vitamin B12 (p ≈ 0.02), and vitamin D (p < 0.0001). Women's menstrual status did not significantly influence the development of iron deficiency. CONCLUSIONS: Use of a composite based on guidelines proposed by the AACE, TOS, and the ASMBS appears to be effective for preventing iron and vitamins A, B1, B12, and D deficiencies in the LRYGB patients during the first postoperative year. Separation of calcium and Fe does not need to be mandatory. Even with simplification, compliance is far from universal.
