BACKGROUND Chyle leakage with chylous ascites is a rare complication of abdominal surgery, and few cases have been reported following cholecystectomy. This report is of a 64-year-old man with chyle leak following laparoscopic cholecystectomy and describes the diagnosis and approach to treatment. Immediate diagnosis, although challenging, remains imperative. Frequently, patients manifest nonspecific symptoms, such as abdominal discomfort or nausea. They can also exhibit milky discharge from drains and wounds. Abdominal fluid analysis is fundamental for diagnosis. The existence of elevated triglyceride levels in peritoneal fluid is indicative of chyle leakage. CASE REPORT We present a case report of a 64-year-old man with chyle leakage after laparoscopic cholecystectomy for acute cholecystitis, on postoperative day 2. A milky-white fluid was drained, and diagnosis was confirmed with elevated triglycerides upon fluid analysis. Chyle leakage decreased gradually until complete resolution at postoperative day 7, after dietary modifications and the closed-suction silicone drain was removed. The patient was symptom-free at a 2-month follow-up. CONCLUSIONS Although chyle leakage is a rare postoperative complication of laparoscopic cholecystectomy, early diagnosis and rapid multidisciplinary management are required. It is vital to consider this diagnosis even if the course of laparoscopic cholecystectomy was uncomplicated and with no anatomical variation. Thus, a closed-suction silicone drain and close monitoring of output is essential for early diagnosis. The dietary modification constitutes a cornerstone in the management of chyle leakage, and a surgical approach should be preserved for patients for whom the conservative approach fails or who have large volumes of chyle.

BACKGROUND Bisphosphonates and anti-receptor activator of nuclear factor kappa B antibodies are used to treat bone diseases associated with increased osteoclast activity, including myeloma. However, they can cause osteonecrosis of the jaw, known as medication-related osteonecrosis of the jaw. This report presents a case of a patient with a history of myeloma who required posterior maxilla resection for bisphosphonate-related osteonecrosis of the jaw, in which preoperative embolization prevented unexpected bleeding related to vascular injury and allowed for a safe procedure with minimal bleeding. CASE REPORT An 84-year-old man presented to our department with a 3-year history of purulent drainage and bone exposure in the right maxilla. Based on the clinical findings at the initial visit, the clinical diagnosis was bisphosphonate-related osteonecrosis of the jaw, and the patient underwent a partial right maxillary osteotomy. This surgery was associated with a risk of unexpected bleeding from a branch of the maxillary artery during the posterior maxilla resection. A catheter-based embolization of the maxillary artery was performed the day before performing a partial maxillectomy to avoid unexpected bleeding risk. Thus, no abnormal bleeding occurred during partial maxillectomy, and no postoperative complications occurred for 3 years. CONCLUSIONS In the surgical treatment of medication-related osteonecrosis of the jaw, preoperative vascular embolization of the peripheral maxillary artery beyond the middle meningeal artery bifurcation is a valuable technique for safe maxillectomy involving the posterior maxilla.

BACKGROUND Sodium-glucose co-transporter 2 inhibitors (SGLT2), such as empagliflozin, used to treat type 2 diabetes mellitus (DM), can increase the risk of infections, including urinary tract infections and osteomyelitis, especially in elderly patients. The use of SGLT2 inhibitors has been increasing dramatically in the last few years. Therefore, their adverse effects and complications have also been increasing. Herein, this report describes a 73-year-old man with type 2 DM treated with empagliflozin presenting with asymptomatic bacteriuria, vertebral osteomyelitis and iliopsoas abscess due to Klebsiella pneumoniae. CASE REPORT We report a 73-year-old man with DM on empagliflozin who presented with back pain of 1-month duration with elevated inflammatory markers. On lumbar spine magnetic resonance imaging (MRI), he was found to have lumbar vertebral osteomyelitis and left iliopsoas abscess. His symptoms were improved with abscess drainage and antimicrobial therapy. The source of infection was most likely asymptomatic bacteriuria, which may have been secondary to empagliflozin treatment, as evidenced by the urine, the blood, the bone and abscess cultures revealing growth of Klebsiella pneumoniae with the same susceptibility profile. CONCLUSIONS This particular case reinforces the significance of potential complications of DM and SGLT2 inhibitors' adverse effects, especially the increased risk of infections, and can aid clinicians in expanding the differential and enabling them to reach an accurate diagnosis and appropriate management. Although vertebral osteomyelitis is a less common cause of back pain, physicians should keep it in the differential diagnosis whenever a patient's back pain is chronic and associated with motor weakness.

BACKGROUND Massive chylous leakage represents a rare yet potentially life-threatening complication following neck dissection, and its occurrence is even less common in the context of endoscopic thyroid surgery. Chylous leakage poses significant clinical management challenges, encompassing prolonged hospitalization, nutritional deficiencies, electrolyte imbalances, and the potential for infection. It is imperative for surgeons to remain vigilant and proactive in recognizing and managing chylous leakage to mitigate its potential impact on patient outcomes. CASE REPORT A 37-year-old woman presented with a thyroid nodule, and subsequent fine-needle aspiration biopsy confirmed the diagnosis of papillary thyroid carcinoma. She then underwent endoscopic thyroidectomy with central lymph node dissection via a bilateral areola approach and experienced significant postoperative chylous leakage. Various conservative management strategies were used to treat the leak, including fasting, parenteral nutrition, maintenance of electrolyte balance, and continuous infusion of somatostatin. After failure of a series of conservative treatments, the patient underwent a reoperation to address the leak via the initial approach. After identification of the leak site, the residual end of the lymphatic vessel was clamped with a biological clamp, and no further chylous leakage was observed. The drainage was removed 4 days after the second operation, and the patient was discharged on the fifth day. During follow-up, no abnormalities were observed. CONCLUSIONS Managing significant chylous leakage poses a challenge for surgeons. This complication is rare following endoscopic thyroidectomy with central lymph node dissection, and there remains a lack of experience in effective prevention and treatment. We aim to raise awareness through our case report.

BACKGROUND Renal osteodystrophy is a serious complication of advanced chronic kidney disease (CKD). It predisposes the patient to fragility fracture and an increased risk of mortality. CASE REPORT We present the case of a 50-year-old male patient with stage 4 CKD and consequent renal osteodystrophy, who presented with a history of a recent provoked seizure, a severe electrolyte imbalance, and excruciating pain in the hip region. He had no history of a fall or trauma. A radiographic evaluation confirmed the rare finding of a bilateral femoral neck fracture. Upon stabilizing the patient, he was surgically managed with a bilateral hemiarthroplasty. A postoperative radiograph revealed a well-fixed prosthesis with no post-surgical complications. The patient had a full recovery. At the last follow-up visit, the patient was fully functional and had resumed normal activities. CONCLUSIONS This is a rare report with unusual mechanism of injury, involving a case of bilateral femoral neck fragility fractures, secondary to renal osteodystrophy in a stage 4 CKD patient. It draws the attention of medical care providers to the high risk of femoral fragility fractures that are secondary to renal osteodystrophy. Hemiarthroplasty is a safe and highly efficacious surgical option for managing such cases. This case also reiterates the dire need for greater public awareness and knowledge of CKD. Early diagnosis and treatment can substantially mitigate the associated morbidity and mortality.

BACKGROUND Malignant peritoneal mesothelioma (MPM) is a rare, lethal tumor of serous membranes. The most common factor reported in association with MPM is asbestos exposure, while viral infections, genetic predisposition, paraneoplastic syndrome, and altered immunity have been described as well. The diagnosis can be challenging among those with lower tumor burden as well as nonspecific symptoms, and it is not unusual to discover the diagnosis incidentally. CASE REPORT A middle-aged woman with decompensated cirrhosis underwent extensive pre-transplant workup, showing no evidence of malignancy. She had a personal history of asbestos exposure and family history of MPM in the extended family. During transplant surgery, a few peritoneal nodules were noted, leading to termination of the procedure. Pathological analysis confirmed malignant MPM. A multidisciplinary discussion led to following a conservative treatment approach without any intervention, due to higher risk of worsening hepatic decompensation associated with peritonectomy and intraperitoneal chemotherapy. The patient's hepatic decompensation resolved 6 months after the aborted liver transplant operation. Since the diagnosis of MPM, positron emission tomography scans have shown no recurrence of MPM for 3 consecutive years. CONCLUSIONS This is the first case of MPM diagnosed incidentally during a liver transplantation surgery. This case highlights the challenges in the diagnosis and management of MPM in a patient with decompensated liver disease. A multidisciplinary approach and following a consensus decision led to prolonged survival in the described patient.
