A 33-year-old female presented with a right cervical mass. Contrast computed tomography showed a multilocular tumor with a clear border and heterogeneous contents including fat and calcification. The tumor was located adjacent to the vagus and recurrent nerves. To avoid injury of these nerves, we resected the tumor through a median sternotomy and right cervical lateral incision. Intraoperative neural monitoring was performed using an NIM TriVantage EMG tube. After the surgery, no neuropathy such as hoarseness was recognized...

BACKGROUND: The unilateral interhemispheric approach is a well-known operative technique for distal anterior cerebral artery (DACA) aneurysms. However, this approach presents several risks, such as postoperative venous infarction due to occasional sacrifice of the parasagittal bridging vein or postoperative frontal lobe damage due to retraction force. To overcome these risks, we used a bifrontal craniotomy with a straight dural incision and cutting of the superior sagittal sinus (SSS)...

BACKGROUND: The craniovertebral junction (CVJ) may be affected by several diseases. It is an anatomically complex region, involving osteo-ligamentous, vascular and nervous structures, which makes surgeries challenging. In case of ventral compression an anterior approach is preferable, although a posterior fixation is often required. Anterior trans-mucosal approaches are associated with high rates of complications. However, decompression and fixation using retropharyngeal (RF) extra-mucosal approaches may result challenging...

Transcutaneous bone biopsy (TCB) is the gold standard for taking microbiological specimens in diabetic foot osteomyelitis (DFO), but this technique is not widely used in diabetic foot care centers. We aimed to evaluate the reliability of per-wound bone biopsy (PWB) cultures by comparing them with concomitant TCB cultures obtained through healthy skin. This is a prospective monocentric study including patients seen in consultation for clinical and radiological diabetic foot osteomyelitis with positive probe-bone tests between April 2015 and May 2018...

Surgical telementoring systems have gained lots of interest, especially in remote locations. However, bandwidth constraint has been the primary bottleneck for efficient telementoring systems. This study aims to establish an efficient surgical telementoring system, where the qualified surgeon (mentor) provides real-time guidance and technical assistance for surgical procedures to the on-spot physician (surgeon). High Efficiency Video Coding (HEVC/H.265)-based video compression has shown promising results for telementoring applications...

BACKGROUND AND AIM: Esophageal stricture is a major complication of large areas endoscopic submucosal dissection (ESD). Until now, the critical mechanism of esophageal stricture remains unclear. We examined the role of mucosal loss versus submucosal damage in esophageal stricture formation after mucosal resection using a porcine model. MATERIALS AND METHODS: Twelve swine were randomly divided into two groups, each of 6. In each group, two 5-cm-long submucosal tunnels were made to involve 1/3rd of the widths of the anterior and posterior esophageal circumference...

Angiogenesis during wound healing is essential for tissue repair and also affected during cancer treatment by anti-angiogenic drugs. Here, we introduce a minimally invasive wound healing model in the mouse ear to assess angiogenesis with high spatiotemporal resolution in a longitudinal manner in vivo using two-photon microscopy in mice expressing GCaMP2 in arterial endothelial cells. The development of vascular sprouts occurred in a highly orchestrated manner within a time window of 8 days following wounding...

OBJECTIVEThe purpose of this study was to investigate the effect of tranexamic acid (TXA) compared to placebo in low-risk adult patients undergoing elective minor lumbar spine surgery-specifically with respect to operative time, estimated blood loss, and complications. Studies have shown that TXA reduces blood loss during major spine surgery. There have been no previous studies on the effect of TXA in minor lumbar spine surgery in which these variables have been evaluated.METHODSThe authors enrolled patients with ASA grades 1 to 2 scheduled to undergo lumbar decompressive surgery at Middelfart Hospital into a double-blind, randomized, placebo-controlled, parallel-group study...

This is the first report of laparoscopic-endoscopic cooperative surgery (LECS) for an ileal tumor. A 50-year-old man was admitted to our hospital with a positive fecal occult blood test. Colonoscopy detected a submucosal tumor with intussusception located in the ileum, 10 cm oral from the Bauhin valve. On further examination, he was diagnosed with an ileal lipoma. There were no signs of malignancy. LECS was performed for the ileal tumor. After submucosal elevation by injecting saline solution, a mucosal incision was made circumferentially along the tumor...

Pyoderma gangrenosum is a rare ulcerating neutrophilic dermatosis. We describe the case of a 28-year-old woman with pyoderma gangrenosum in the perineal region during pregnancy. Cytological analysis of a skin biopsy specimen showed neutrophilic infiltrates across all the layers of the dermis, confirming the diagnosis of pyoderma gangrenosum. Determining a management plan, including the mode of delivery, was difficult. Oral prednisolone was started and her ulcer started to improve, but she still had the ulcer when she reached full term...
