Transcanal endoscopic assisted skull base endolymphatic sac tumor resection: A rare disease with advanced technology

Endolymphatic sac tumors(ELSTs) are rare, papillary adenomatous tumors that arise from the endothelium of the endolymphatic sac. We demonstrate a difficult case of endolymphatic sac tumor and how it is managed via transcanal endoscopic assisted technique, with discussion of feasibility of transcanal approach to lateral skull base tumor.

Endoscopic vacuum assisted closure of esophagogastric anastomosis dehiscence:A case report

BACKGROUND Esophagogastric leakage is one of the most severe postoperative complications.Partial disruption of the anastomosis,can be successfully treated with an endoscopic vacuum assisted closure(E-VAC).The advantage of that method of treatment is the ability to adjust a vacuum dressing individually to the size of the dehiscence and thus to reduce the risk of a secondary fistula or abscess.The authors present two patients with postoperative gastroesophageal leakage treated successfully with E-VAC.CASE SUMMARY Two male patients developed a potentially life threatening esophagogastric leakage.Patient A underwent resection of the distal half of the esophagus and upper part of the stomach due to Siewert type II adenocarcinoma of the gastroesophageal junction.Proximal resection of the stomach was performed in the patient B after massive bleeding from Mallory-Weiss tears.Both patients were treated successfully with an individually adapted E-VAC with concomitant correction of fluid and electrolyte disturbances,and treatment of sepsis with appropriate antibiotics.CONCLUSION Endoscopic vacuum closure is an effective alternative to endoscopic stenting or relaparotomy.Through individual approach it allows a more accurate assessment of healing.

Trans-eyebrow supraorbital endoscope-assisted keyhole approach to suprasellar meningioma in pediatric patient:case report and literature review

Background:Meningiomas are rather uncommon tumors in the pediatric population,differing significantly from those found in adults by their atypical location,higher rate of more malignant types,consequently higher risk of recurrence and a less favorable outcome.Even in children,suprasellar meningiomas without dural matrix are rare findings mimicking more common suprasellar lesions.Case presentation:Here we describe a case of a 12-year-old girl who presented with a rapidly progressing chiasmal syndrome and was diagnosed by MRI with an unusual suprasellar tumor that could not fit the diagnoses expected in a case of a parasellar mass in a child,similar to a craniopharyngioma or optic pathway glioma.After multiple clinical investigations,the tumor etiology was still unclear,so the preferred option of treatment was surgical resection.An endoscope-assisted gross total resection through a supraorbital keyhole approach was performed uneventfully,with total vision recovery in a short time.Benign meningiomas located in the skull base without dural attachment appear to be rare,even in pediatric patients.Conclusion:Differential diagnoses of suprasellar and para sellar tumor lesions in pediatric patients can be confusing.There are peculiar features of pediatric tumor diseases that should be considered while working out the management strategy.The main principle of meningioma treatment is the highest possible extent of resection minimally affecting the quality of life.

Hybrid minimally invasive coronary artery revascularization

Background Hybrid coronary revascularization （HCR） is an altemative coronary revascularization strategy that combines a minimally invasive, survival advantage of the left internal mammary artery （LIMA） -left anterior descending （LAD） coronary artery bypass with less-invasive percutaneous coronary intervention （PCI） to non-LAD coronary lesions by using drug-eluting stents. We report our experience of hybrid minimally invasive approach in 15 patients. Methods From December 2012 to October 2013, 15 patients underwent revascularization of the left anterior descending artery through minimally invasive coronary artery bypass grafting （MIDCAB）. All patients by endoscopic assist beating heart coronary artery bypass grafting. Seven patients were scheduled for a hybrid procedure. Percutaneous coronary intervention of non- LAD was performed 3 to 5 days preoperatively. Demographic data, perioperative outcome, and annual follow-up were obtained from all the patients. Results In-hospital mortality was 6.67%. The rate of conversion to full median sternotomy was 13.3%. Ventilation time was 6.9 ± 5.1 h. Blood loss volume was 241 ± 67.8 mL. ICU stay was 21.3 ± 10.8 h. Hospital postoperative stay lasted for 7.5 ± 1.3 days. Prior to PCI patients showed 100% patent LIMA （Tables 3 and 4）. A mean follow-up was 8.5 months. One year graft patency rate was 100% （8/8 patients for 254-slice tomography）. Two patients required reintervention. Conclusions Minimally invasive hybrid coronary revascularization is a safe, feasible and efficacious approach with good results and should be performed in selected patients by surgeons with experience in minimally invasive bypass surgery plus collaboration with cardiologists, eluting stents.
