A case of pseudohyperkalemia in a patient presenting with leucocytosis and high potassium level: a Case Report

Pseudohyperkalemia can appear in a variety of settings and should be recognized early. Treatment of pseudohyperkalemia can lead to an inappropriate decrease of actual serum potassium levels which may lead to life threatening conditions. In the case presented, an 81-year-old male presented with massive leucocytosis and an extremely elevated potassium level. This case report emphasizes the importance of recognizing pseudohyperkalemia in a patient with a severely increased potassium and WBC level; such patients may be clinically asymptomatic or may have a normal ECG

Laparoscopic bilateral cortical-sparing adrenalectomy for pheochromocytoma

© 2016, Springer Science+Business Media New York. Introduction: Since laparoscopic adrenalectomy for pheochromocytoma was reported in 1992, the laparoscopic technique has largely replaced the open approach [4]. Numerous studies have demonstrated that the laparoscopic approach is associated with decreased blood loss, shorter hospitalization, faster recovery, and lower cost [1]. Conversion rates are reported at less than 5.5 %, yet concern still exists that intraoperative hypertensive crisis may be more severe with laparoscopy due to increased intraabdominal pressure [3]. Bilateral pheochromocytomas are common in patients with multiple endocrine neoplasia type 2 (MEN 2) or von Hippel-Lindau (VHL) disease. Total adrenalectomy commits the patient to lifelong steroid hormone replacement and the risk of Addisonian crisis after bilateral adrenalectomy [5]; [8]. The risk of malignant pheochromocytomas in patients with or without MEN 2 or VHL is low. The current literature supports cortical-sparing adrenalectomy in patients with bilateral pheochromocytomas [2, 7, 10]. This video presents a patient with bilateral pheochromocytomas who underwent bilateral laparoscopic cortical-sparing adrenalectomies. Methods: A 40-year-old female presented to her primary care physician with a history of a hypertensive crisis that required an emergent cesarean section. Her workup revealed elevated urinary metanephrines, and a CT scan showed a left adrenal lesion measuring 3.9 cm and a right adrenal lesion measuring 2.7 cm. After undergoing alpha blockade, she was consented for bilateral partial adrenalectomies. A left partial adrenalectomy was performed first using four ports. The ports were then closed and the patient was repositioned in a left lateral decubitus position for a subsequent right partial adrenalectomy. Results: The patient had an uncomplicated hospital course and was discharged home on postoperative day 4. She returned for follow-up at 2 weeks and 1 month and had returned to her normal activities. Testing for MEN and von Hippel-Lindau was both negative. Her electrolyte and cortisol levels normalized, and she was weaned off her postoperative steroids by week five. At 1-year follow-up, she remains off steroids and no longer requires anti-hypertensive medications. Conclusion: Laparoscopic adrenalectomy is the gold standard for removal of benign lesions of the adrenal gland. Bilateral pheochromocytomas are more common in the presence of hereditary conditions such as MEN and von Hippel-Lindau and should be ruled out [8, 10]. The risk of Addisonian crisis and lifelong steroid replacement should prompt cortical preservation with bilateral disease [9]. Laparoscopic bilateral partial adrenalectomies should be considered in patients with bilateral pheochromocytomas [6]. Finally, all patients undergoing pheochromocytoma excision require lifelong follow-up to monitor for recurrence

Laparoscopic Puestow: lateral pancreaticojejunostomy.

© 2016, Springer Science+Business Media New York. Introduction: Chronic pancreatitis is a painful inflammatory disease that leads to progressive and irreversible destruction of pancreatic parenchyma [1]. A lateral pancreaticojejunostomy, also known as the Puestow procedure, is performed for symptomatic chronic pancreatitis associated with a dilated pancreatic duct secondary to calcifications or strictures [4]. An open approach is used traditionally due to the complexity of the case, and there have only been a handful of laparoscopic case reports [2]. This video depicts a laparoscopic lateral pancreaticojejunostomy for chronic pancreatitis. Methods: A 45-year-old gentleman with a 20-year history of chronic alcohol abuse presented with diffuse abdominal pain. His pain was worse postprandially and associated with loose stools. A computed tomography scan revealed multiple calcified deposits within the body and tail of the pancreas, and a dilated pancreatic duct measuring 1.4 cm with a proximal obstructing calcified stone. A 5-port foregut technique was used, and a 15-cm pancreatic ductotomy was performed with an ultrasonic scalpel. Calcified stones were cleared from the duct, and a roux-en-y pancreaticojejunostomy was performed using a hand-sewn technique. Results: The patient had a relatively uncomplicated hospital course with return of bowel function on postoperative day 4. His patient-controlled analgesic device was discontinued on post operative day 3. He was ambulating, tolerating a regular diet and discharged home on postoperative day 5. At 12- and 26-month follow-up, he remains off narcotics, but still requires 1–2 tabs of pancreatic enzyme replacement per meal. Most importantly, he has not had any alcohol for over 2 years. Conclusion: The two primary goals in treating chronic pancreatitis include long-term pain relief and improvements in quality of life [3]. For patients with chronic pancreatitis and a dilated pancreatic duct, a laparoscopic lateral pancreaticojejunostomy may be an effective approach to decrease pain and improve quality of life
