UNLABELLED Antrochoanal polyp (ACP) or Killian polyp is a benign nonatopic lesion of the maxillary sinus. Patients usually present nasal obstruction. Many surgical options for the treatment of ACPs have been suggested to minimize postoperative recurrence. The endoscopic nasal approach is a surgical option for maxillary intrasinusal resection of the polyp implantation through the maxillary ostiu...

Although choanal polyps frequently arise from the maxillary sinus, a choanal polyp originating from the inferior turbinate is a rare entity. A 14-year-old girl who had a history of bilateral nasal obstruction with snoring, mouth breathing and nasal discharge for 10 years was presented. On endoscopic examination, a polypoid mass completely obliterated the right nasal cavity. The left choana was ...

BACKGROUND The waiting time for functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) in the Canadian public healthcare system can be lengthy. Many such patients have significant nasal obstruction resulting in a poor quality of life. A simple and safe office-based polypectomy device to debulk nasal polyps allows immediate alleviation of...

We present a rare case of adult intussusception due to cecal lymphangioma. A 30-year-old female was admitted to our hospital with abdominal pain and a palpatable mass on the right lower quadrant. Preoperative radiologic studies by ultrasound and computed tomography showed ileocolic intussusception with a multiseptated cystic tumor as a leading point on the cecum. An ileocecectomy was performed,...

The incidence of lymphangiomas in the gastrointestinal tract is low, particularly in the colon and rectum, and most cases are solitary. Lymphangiomatosis of the colon are encountered infrequently with only one report in the English literature, and polypectomy was performed for the diagnosis in that case report. However, trends in the diagnosis of lymphangiomatosis of colon have been changing si...

We report a case of a 53-year-old man who presented with a history of recurrent fever with intermittent jaundice over a few months. Ascending cholangitis was suspected. Abdominal ultrasound showed no gallstone and an only slightly dilated common bile duct (CBD). The patient’s blood tests were normal. The patient was referred for endoscopic ultrasound (EUS). In the endoscopic suite, the patient ...

A 63-year-old man presented to our hospital with chronic abdominal pain associated with intermittent periods of postprandial vomiting. Esophagogastroduodenoscopy and endoscopic ultrasound confirmed the diagnosis of a lipoma in the second portion of the duodenum. Owing to the unavailability of a therapeutic gastroscope, a conventional polypectomy snare was modified (▶Fig. 1) in order to be used ...

In the last years, a distinctive interest has been raised on large polypoid and non-polypoid colorectal tumors, and specially on flat neoplastic lesions ≥20 mm tending to grow laterally, the so called laterally spreading tumors (LST). Real or virtual chromoendoscopy, endoscopic ultrasound or magnetic resonance should be considered for the estimation of submucosal invasion of these neoplasms. Le...
