Broncho-gastric fistula caused by benign gastric ulcer perforation after esophagectomy is very rare. In general anesthesia of a patient with broncho-gastric fistula, in spite of hyperventilation, leakage of the anesthetic gases through fistula may make the patient hypercapneic, and positive pressure ventilation may increase the risk of the pulmanary aspiration by the regurgitation of gastric fluid by stomach distension. For that reason, in this patient, denitrogenation was performed during patient's voluntary respiration with 100% oxygen for 5 minutes, and induction was performed without positive pressure ventilation, and one lung ventilation was carried out. Hypoxemia was followed by one lung ventilation because his pulmonary function was moderate obstructive type and his lung was damaged by aspiration of gastric fluid via broncho-gastric fistula. A low level of continuous positive airway pressure (CPAP) has no significant hemodynamic effect and can maintain the patency of nonventilated lung, so hypoxemia induced by one lung ventilation may be reduced. Thus we carried out one lung ventilation with CPAP (10 cmH2O) in nonventilated lung and blocked broncho-gastric fistula with a bronchial blocker for prevention of both regurgitation of gastric fluid and leakage of anesthetic gases. One lung anesthesia was performed without any problem in this case.

PURPOSE: The purpose of the study was to have an in-depth understanding of delivery room nurses'experiences of caring for stillborn babies and their parents. METHODS: After obtaining approval from the Institutional Review Board, data were collected from March 1 to August 30, 2016. A total of six nurses participated in the study. Semi-structured in-depth interviews were conducted and the data subsequently analyzed. RESULTS: Using thematic analysis, six themes were defined and refined: Emotional distress as a result of encountering stillborn babies; Caring for the deceased baby; Concerns for the mother's pain; Consideration for the father; Conflicts between accepting and dismissing parents' requests; and Strong mindset for the stillborn babies and their parents. CONCLUSION: The results showed that the nurses' experiences of caring for stillborn babies and their parents might be a difficult and lonely process. However, it could also be a process of attaining maturity by finding meaning and value in one's work. It would be helpful for the delivery room nurses to share examples of effective communication, train through simulation, and learn useful strategies that each nurse can use.

5.Uterine Cervical Cancer: Emphasis on Revised FIGO Staging 2018 and MRI
Journal of the Korean Radiological Society 2021;82(5):1083-1102
Uterine cervical cancer is a common gynecological cancer prevalent in Korea. Early detection, precise diagnosis, and appropriate treatment can affect its prognosis. Imaging approaches play an important role in staging, treatment planning, and follow-up. MRI specifically provides the advantage of assessing tumor size and disease severity with high soft tissue contrast. The revised version of the International Federation of Gynecology and Obstetrics (FIGO) staging system has been introduced in 2018, which incorporates subdivided primary tumor size and lymph node metastasis. In this review, the staging of uterine cervical cancer based on previous studies, the recently revised FIGO staging, and various post-treatment images are primarily described using MRI.

BACKGROUND: Endoscopic Ultrasonography(EUS), a combination of endoscopy and ultrasonography is one of the most useful tools for diagnosis of digestive system diseases. EUS is useful in staging the primary tumor invasion and regional lymph node metastasis because of its ability to image the gut wall and adjacent structures in unique detail. We performed a study preoperatively for assessing the accuracy and limitation of EUS in gastric carcinoma. METHODS: In 75 patients(Male 54, Female 21, Mean age 62.3 years) with a gastric carcinoma confirmed by endoscopic biopsy, we performed EUS preoperatively. The results were compared with the postoperative histopathologic staging. RESULTS: 1) In assessing the depth of tumor invasion, EUS accuracy on depth of invasion was 76.0% and overstaging and understaging were 14.7% and 9.3%, respectively. 2) In assessing the lymph node metastasis, the accuracy rate of EUS was 65.3%. A rate of false-positive diagnosis was 27.3%, and a rate of false-negative diagnosis was 24.5%.3) In assessing the incidence of lymph node metastasis for each T stage, the involve rate was 10.5% in pT1, 36.4% in pT2, 95.7% in pT3, 100% in pT4. CONCLUSIONS: EUS is the most accurate diagnostic methods presently available to determine tumor infiltration depth and lymph node metastasis.

PURPOSE: As morbidity and mortality resulting from physical trauma have significantly increased, the importance of trauma concerning medical, legal, and socioeconomic issues has been widely documented. Studies of post-traumatic seizure after head trauma have been reported, but mostly in adults. So this study was performed to analyse clinical findings on head trauma patients under 20 years of age. METHODS: The medical records of 230 patients under 20 years of age, who were admitted as head trauma to Chung Ang University hospital from January 1993 till May 1997, were reviewed. RESULTS: The overall incidence of Post-traumatic seizure was 32 of 230 patients in this study. The incidence per age was 16.7% in less than 5 year, 12.2% in 6-10 year, 11.4% in 11-15 year, and 14.9% in 16-20 year. We found incidences of Post-traumatic seizure in cases with depressed skull fracture(44.4%), subdural hematoma(28.6%), subarachnoid hemorrhage(28.6%) and intracerebral hemorrhage(21.1%). Of the 230 patients with head trauma, 2.2% had an immediate-onset seizure, 2.6% an early-onset seizure and 9.1% a late-onset seizure. Of the patients with post-traumatic seizure, abnormal EEG findings were found in 50%. EEG abnormalities were slowing (46.2%) and spike(3.8%). Recurrence rate of post-traumatic seizure was 21.9% in this study. We found a high incidence of recurrence in cases of depressed skull fracture, subdural hematoma and epidural hematoma. CONCLUSION: Considering the great influence of seizure on a child's development and long-term prognosis, prevention based on post-traumatic seizure risk assessment is important and antiepileptic prophylaxis should be considered as disk factors.
