The aim of this study is to review our experience in treating indirect inguinal hernia in pediatric patients. Methods:We retrospectively studied a total of 43 patients who underwent percutaneous internal ring suturing (PIRS) for indirect inguinal hernia from January 2016 to September 2018. The participants included 29 boys and 14 girls. There were cases of bilateral internal inguinal hernia (n=12), right indirect inguinal hernia (n=16), and left indirect inguinal hernia (n=15). Their mean age was 3.8±2.9 years, and mean body weight was 16 kg. Clinical features and surgical outcomes were analyzed.Results: Mean operating time was 35 min for unilateral inguinal hernia and 40 min for bilateral inguinal hernia. There were five cases of intraoperative bleeding (12%) during needle insertion. In two cases, stress test resulted in escape of gas into the hernial sac and a second suture was inserted. The contralateral patent processus vaginalis was present in six (14% of cases) and closed. Follow-up was 6~30 months. Mean postoperative hospital stay was 1.2 days. No recurrence hernia and postoperative complications were reported. Conclusion:Although this study investigated a small number of cases and the surgical experience was rather limited, the PIRS technique was shown to have advantages such as a short learning curve and its aid in detecting contralateral hernias. In this study, there were no reports of recurrence, metachronous inguinal hernias, and postoperative complications.

Purpose:The follicular variant of papillary thyroid carcinoma (FVPTC) is difficult to diagnose due to pathologic features. There is also debate on the optimal extent of surgery. We separated FVPTC into two groups and compared the clinical features in an attempt to apply the treatment. Methods: All 40 patients with FVPTC who were diagnosed between 1990 and 2009 were reviewed and separated into two groups, an encapsulated group and an infiltrative group, based on whether a capsule was formed or infiltration occurred. These two different subtypes of FVPTC were compared on the traits of sensitivity of diagnosis and clinicopathologic features. Results: After review by a pathologist, 21 of 40 patients (55%) were found to have encapsulated tumors, and 18 patients (45%) had infiltrative tumors. There was no difference in age, sex, or size. Patients with encapsulated FVPTC had a significantly lower rate of lymph node metastasis (4.5%), multicentric tumors (18.2%), and thyroid capsular invasion (9.1%) compared with the infiltrative tumor group (50%, 50% and 50%, P＜0.05). There was no difference in FNA sensitivity between the two groups, but the sensitivity to frozen biopsy was higher in the infiltrative group. There was no recurrence in the encapsulated group, but 4 patients (22.2%) experienced recurrence in the infiltrative group. Conclusion: FVPTC can be separated into two subgroups by histologic features, and there are some clinicopathologic differences between the two groups. Patients who had encapsulated FVPTC had a lower rate of lymph node metastasis, multicentric tumors, and thyroid capsular invasion. They also showed a lower rate of recurrence than the infiltrative group. It is suggested that the encapsulated group can be treated with limited surgery and the infiltrative group needs aggressive treatment. (Korean J Endocrine Surg 2011;11:256-261)

We experienced a case of 1 patient who died from rhabdomyolysis-related complications after colonoscopy. A 60-year-old man had undergone an ‘uncomplicated’ colonoscopic polypectomy. Approximately 10 hours following this procedure, the patient complained of increasing left abdominal pain. His computed tomography image showed free gas, but his operative findings revealed no macroscopic perforation or abscess formation. Eight hours after the operation, the patient presented with myoglobulinuria, and we diagnosed the condition to be rhabdomyolysis. Based on this case, we recommend that rhabdomyolysis be added to the list of complications following a colonoscopic procedure. Moreover, for prevention and early treatment, endoscopists should be attentive to the risk factors and signs/symptoms of rhabdomyolysis.
