Objective : Endoscopic third ventriculostomy is gaining popularity as a minimally invasive surgical option for certain types of hydrocephalus as an alternative to shunting. The authors have tried to fenestrate down to the subdural space passing through the prepontine cistern to lessen or avoid the chance of redoing due to healing. Materials and Method : A 48-year-old male patient with several years of intractable headache was presented. Magnetic Resonance Image(MRI) of the brain revealed marked ventricular dilatation with stenotic cerebral aqueduct. A 2.3mm flexible steerable endoscope($Neuroview^{(R)}$) was introduced via precoronal route and accessed to the third ventricular floor. Using 3-French Fogarty balloon catheter, thin third ventricular floor and the arachnoid membrane of the prepontine cistern were fenestrated, so called "double fenestration". To confirm the fenestration, subdural compa-rtment of the left abducens nerve was identified during the procedure. Forceful pulsating flow through the orifice convinced the patency of the opening. Results : The patient was discharged on the third postoperative day without any postoperative complications. The postoperative follow-up MRI of the brain, at second and sixth months, clearly demonstrated the flow void through the third ventricular floor. Conclusions : Endoscopic third ventriculostomy was successfully performed on an adult hydrocephalus patient with aqueduct stenosis. The third ventricular floor and arachnoid membrane of the prepontine cistern were fenestrated to achieve double fenestration to minimize the chance for failure. The details of this procedure and results are described.

Purpose: We evaluate the role of transanal tube drainage (TD) as a conservative treatment for patients with anastomotic leakage (AL). Methods: Patients treated for AL who had undergone a low or an ultralow anterior resection with colorectal or coloanal anastomosis for the treatment of rectal cancer between January 2013 and January 2017 were enrolled in this study. The data were collected prospectively and analyzed retrospectively. The primary outcomes were the diagnosis and the management of AL. Results: Two hundred thirteen consecutive patients, 122 males and 91 females, were included. The mean age was $66.91{\pm}11.15years$, and the median body mass index was $24kg/m^2$ (range, $20-35kg/m^2$). The median tumor distance from the anal verge was 8 cm (range, 4-12 cm). Ninety-three patients (44%) received neoadjuvant therapy for nodal disease and/or locally advanced rectal cancer. Only 13 patients (6%) developed AL. Six patients developed subclinical AL as they had a defunctioning ileostomy at the time of the initial procedure. They were treated conservatively with TD under endoscopic guidance in the endoscopy unit and received intravenous antibiotics. Six weeks after discharge, these 6 patients underwent follow-up flexible sigmoidoscopy which showed a completely healed anastomotic defect with no residual stenosis. Seven patients developed a clinically significant AL and required reoperation with pelvic abscess drainage and Hartmann colostomy formation. Conclusion: These results suggest that TD for management of patients with AL is safe, cheap, and effective. Salvaging the anastomosis will help decrease the need for Hartmann colostomy formation. Proper patient selection is important.

Purpose: Foreign body swallowing is common in children. Most of foreign bodies passed upper esophagus are removed spontaneously. But recently, therapeutic endoscopy in children is widely used. In this study, we reviewed gastric foreign bodies regarding types, location, interval from swallowing, complications, and treatment or method of removal. Methods: We reviewed medical records of 96 cases with foreign bodies in gastrointestinal tract at Department of Pediatrics in Gyeongsang National University Hospital (GNUH) from Feb 1987 to Feb 2002. Results: The peak age of patients (male=60, female=36) with foreign bodies in gastrointestinal tract was 2 to 5 years of age. Sixty two patients (64.5%) were asymptomatic. The location of foreign bodies in gastrointestinal tract were detected by simple X-ray in eighty one patients (86.0%), barium study (1 case), and gastroduodenoscopy in 37 cases. The most common location was stomach (63.5%). The most common foreign body was coin (41.7%). In thirty seven cases (38.5%), foreign bodies were removed with flexible gastroduodenoscopy. Fifty four patients (56.3%) visited GNUH in 24 hours after swallowing foreign bodies. The long interval (over 24 hours) of swallowing of foreign bodies is related with high frequency of endoscopic removal. Conclusion: The flexible gastroduodenoscopy was effective in diagnosis and removal of foreign bodies. Further studies for indication and validity of endoscopic removal of foreign bodies in upper gastrointestinal tract are needed.
