    Colonic Lymphangiomatosis
    Mir, Adil S.; Abel, William F.; Lebel, David P. (Springer, 2023-05)
    Lymphangiomas are benign malformations of the lymphatic vessels which can be primary or secondary in etiology. Colonic involvement is rare, and the diagnosis is mostly incidental. Sometimes, the initial endoscopic appearance can be misleading. We present a case of colonic lymphangiomatosis presenting with free air under the diaphragm requiring surgical removal of the involved portion of the colon. The diagnosis was confirmed by the pathology of the resected specimen and its correlation with prior clinical information. The patient recovered well with an uneventful postoperative course and follow-up. This case demonstrates a rare complication of colonic lymphangiomatosis prompting definitive treatment by surgical resection.

    Massive infected pancreatic necrosis in an 8-year-old: Endoscopic management
    Abel, William F.; Kesar, Varun; Wasserman, Reid D.; Kumar, Manoj; Patel, Vishal; Yeaton, Paul; Kesar, Vivek (Wiley, 2024-02-14)
    Pancreatitis is a condition much more commonly found in adults, but when diagnosed in the pediatric population, is often due to medications, congenital pathology, and critical illness. This patient had previously undergone treatment with 6-mercaptopurine and presented with pancreatitis that eventually worsened to a walled-off necrotic collection with paracolic extensions reaching the pelvis. Given clinical worsening with development of shock, procedural options for source control were weighed with gastroenterology, pediatric surgery, and interventional radiology, before pancreatic necrosectomy was determined to be the treatment of choice, given the adjacency of the collection to the stomach. A total of three separate endoscopic pancreatic necrosectomy procedures were performed and the patient s clinical status improved greatly, with vast improvement later seen on outpatient imaging. This successful treatment course argues for the efficacy of pancreatic necrosectomy even in very large walled off collections, and most importantly, lead to a positive outcome in this young patient.

    A Therapeutic Approach to Primary Hyperparathyroidism: A Collaborative Evaluation Between Endocrinology and Surgery
    Behnke, Andrew J.; Tershak, Daniel R.; Abel, William F.; Bankole, Adegbenga A. (Cureus, 2023-01-24)
    Introduction: Primary hyperparathyroidism (PHPT) is a disorder in which one or more parathyroid glands overproduce parathyroid hormone, leading to hypercalcemia. It may present with symptoms like constipation, abdominal pain, psychiatric complaints as well as signs of nephrolithiasis, and osteoporosis that may need surgical treatment. PHPT is often underdiagnosed and undertreated. Our study aimed to review hypercalcemia in a single center to evaluate for undiagnosed PHPT. Methods: A group of 546 patients from Southwest Virginia was selected using the EMR Epic (Epic Systems, Verona, USA) who had a diagnosis of hypercalcemia in the previous six months. Charts were manually reviewed, and patients were excluded based on the lack of hypercalcemia as well as previous testing of parathyroid hormone (PTH) levels. One hundred and fifty patients were excluded because of a lack of documented hypercalcemia. Letters were sent to the patients advising the patients to discuss whether a PTH would be indicated with their primary care provider (PCP). These patients’ charts were re-examined six months later and a determination of whether a PTH level was performed as well as any referrals explicitly for hypercalcemia or PHPT was done. Results: A total of 20 (5.1%) patients had a new PTH test during the time assessed. Of these patients, five received referrals to surgical treatment and six received referrals to endocrinology for treatment (no patients received referrals to both). Of those who obtained a PTH level, 50% of them had significantly elevated PTH levels consistent with the diagnosis of primary hyperparathyroidism. An additional 45% had levels of parathyroid hormone that were in the normal range but or most likely inappropriately normal for the concurrent level of calcium. Only one patient (5%) had a suppressed PTH level. Conclusion: The impact of an intervention on clinician evaluation and treatment of patients with hypercalcemia has been previously tested and shown to be beneficial. In this study, the method of directly sending a letter to patients yielded clinically significant results, with 20 patients out of 396 (5.1%) having a PTH level tested. A majority had an overt or suspected parathyroid disease, and out of them, 11 underwent referral for treatment.
