BACKGROUND: Osteoid osteoma accounts for approximately 10% of all benign bone tumors. The most common sites of osteoid osteoma are the subcortical shaft and metaphyses of long bones, but any other skeletal bone site can be involved. The acetabulum is a rare site according to past reports. This site presents challenges to optimal management because it is anatomically difficult to approach, and because its rarity leads to limited experience with therapeutic procedures. Here, we report for the first time a rare case of osteoid osteoma in the acetabulum that was successfully treated via resection of the nidus and ablation using a standard electrosurgical generator under computed tomographic guidance...

BACKGROUND: Adenocarcinoma-in-situ (AIS) of the uterine cervix is a precursor to cervical adenocarcinoma and may co-exist with both adenocarcinoma and high-grade squamous dysplasia (cervical intraepithelial neoplasia (CIN) 2 and 3). Up to 60% of AIS lesions are detected incidentally following excisional biopsies performed for the treatment of CIN 2/3. To date there are no data regarding risk factors for persisting or progressive cervical neoplasia in these patients. OBJECTIVE: To investigate patient outcomes following incidentally detected cervical AIS after loop electrosurgical excision procedure (LEEP) or cold knife cone (CKC) biopsy performed for the treatment of high-grade cervical intraepithelial neoplasia (CIN)...

Operating Room (OR) scheduling is crucial to allow efficient use of ORs. Currently, the predicted durations of surgical procedures are unreliable and the OR schedulers have to follow the progress of the procedures in order to update the daily planning accordingly. The OR schedulers often acquire the needed information through verbal communication with the OR staff, which causes undesired interruptions of the surgical process. The aim of this study was to develop a system that predicts in real-time the remaining procedure duration and to test this prediction system for reliability and usability in an OR...

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is considered the gold standard for treatment of gastrointestinal variceal bleeding refractory to endoscopic therapy in patients with portal hypertension. Clinically relevant hemorrhage from rectal varices is less frequent than from other sources, and the therapeutic role of TIPS is still ambiguous. Case report: A 57-year-old female patient was referred to us in December 2015 with severe signs of decompensated alcohol-induced liver cirrhosis. During hospitalization, she presented with recurrent hematochezia from rectal varices following electrosurgical snare removal of a rectal adenoma...

Badr Al-Bawardy, Elizabeth Rajan, Louis M Wong Kee Song
BACKGROUND AND AIMS: Endoscopic full-thickness resection (EFTR) allows for definitive diagnosis and treatment of select subepithelial and epithelial lesions unsuitable to conventional resection techniques. Our aim was to evaluate the efficacy and safety of over-the-scope (OTS) clip-assisted EFTR for these lesions. METHODS: Patients who underwent OTS clip-assisted EFTR between June 2014 and October 2015 were analyzed. The procedure involved (1) thermal marking of the periphery of the lesion; (2) lesion suction into the cap of either an OTSC (Ovesco Endoscopy AG, Tübingen, Germany) or Padlock clip (Aponos Medical Corp, Kingston, NH, USA) with or without triprong anchor retraction of the lesion; (3) clip deployment; and (4) en bloc resection of the lesion above the clip using an electrosurgical snare and/or knife...
