Laparoscopic repair of an obturator hernia; a case report of a contemporary surgical technique.

INTRODUCTION AND IMPORTANCE: Small bowel obstruction secondary to an obturator hernia is a rare presentation associated with high mortality. Prior to the development of laparoscopic surgery, a laparotomy would have been the management technique of choice for this rare presentation. CASE PRESENTATION: An elderly female with a bowel obstruction secondary to an obturator hernia presented via the Emergency Department. A laparoscopic approach with the use of a haemostatic gauze plug was performed to repair the defect. CLINICAL DISCUSSION: The evolution of surgical techniques, particularly with laparoscopy has resulted in overall benefits regarding patient outcomes. These benefits include lower post operative morbidity, shorter length of stay and decreased post operative pain. This report discusses a laparoscopic approach and the use of a gauze plug to manage an emergent small bowel obstruction secondary to an obturator hernia. CONCLUSION: The use of a haemostatic gauze agent is an alternate and potentially advantageous approach for an obturator hernia repair in the emergency setting.

A Cautionary Tale: A Case Report Describing a Benign Parotid Oncocytoma Diagnosed as Metastatic Squamous Cell Carcinoma on Fine Needle Aspirate.

Parotid oncocytoma is a rare salivary gland tumour. Management does not require surgical intervention if diagnosed on a preoperative biopsy. A 64-year-old man presented with a parotid mass diagnosed as mcSCC on fine-needle aspiration cytology (FNAC). Surgical histopathology following parotidectomy demonstrated an oncocytoma of the parotid gland. Parotid oncocytomas are rare; therefore, diagnosis can be difficult. An MRI, CT, and US-guided biopsy are required for diagnosis. Ultrasound-guided core biopsy (UGSB) is more sensitive and specific when compared to FNAC for diagnosing malignant tumours. Diagnoses of benign salivary gland tumours on biopsy remain challenging. The aim of this article is to highlight the difficulty of diagnosing salivary gland tumours. We further aim to outline the contributing features that lead to this misdiagnosis and suggest steps to circumvent it in the future. This report describes the challenges in diagnosing salivary gland tumours and outlines the contributing features of this misdiagnosis. We add to the literature an additional case of a parotid oncocytoma.
