        Megacystis-Microcolon-Intestinal Hypoperistalsis Syndrome: A Rare Case Report

        오다솔,김소연,최소진,원혜성 대한주산의학회 2023 Perinatology Vol.34 No.3

        Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is an extremely rare congenital disorder characterized by an enlarged bladder without renal obstruction, decreased intestinal motility, and microcolon. This genetic disease is challenging to diagnose prenatally because of its nonspecific ultrasonographic findings and low incidence. In a case study, a 36-year-old nullipara who was at 24 weeks of gestation and referred to Asan Medical Center with a chief complaint of fetal enlarged bladder. Fetal ultrasonography showed megacystis without definite renal obstruction, normal female genitalia, and a normal amniotic fluid index. Follow-up ultrasonography at 30 weeks of gestation revealed worsening bladder distention accompanied by hydronephrosis. At 34 weeks of gestation, ultrasonography showed dilatation of the stomach and small bowel and polyhydramnios. The final prenatal diagnosis was megacystis associated with hydronephrosis and additional small bowel obstruction. Thus, MMIHS was prenatally suspected. The patient underwent an elective cesarean section at 37 weeks of gestation. A female newborn was delivered, with a birth weight of 2,300 g, and was admitted to the neonatal intensive care unit. No urethral obstruction was confirmed by Foley catheter insertion; however, on neonatal abdominal ultrasonography, a long segment of the microcolon was observed. The newborn failed to defecate and urinate, and genetic testing was performed, which was ultimately diagnosed with MMIHS with an ACTG2 (actin gamma 2, smooth muscle) gene mutation. While MMIHS was once a fatal disease, treatments such as intestinal rehabilitation and transplantation have improved the survival rate. Therefore, prenatal diagnosis is crucial for counseling, early postnatal diagnosis, and treatment.

      • 양성침샘질환 수술에서 Thunderbeat<sup>TM</sup>와 Harmonic scalpel<sup>®</sup>의 유용성에 대한 비교연구

        이형신,김성원,이강대,오다솔,김주현,고윤우,최은창,Lee, Hyoung Shin,Kim, Sung Won,Lee, Kang Dae,Oh, Dasol,Kim, Ju Hyun,Koh, Yoon Woo,Choi, Eun Chang 대한두경부종양학회 2018 대한두경부 종양학회지 Vol.34 No.1

        Background and Objectives: Thunderbeat (TB) and Harmonic scalpel (HS) have been applied to variable head and neck surgery, which are useful for both coagulation and cutting of tissues. However, there have been no comparative studies covering the usefulness of these energy devices in surgery for major salivary gland. In this study, we analyzed the surgical outcomes of two devices in surgery for parotidectomy and submandibular gland (SMG) resection. Materials and Methods: A retrospective chart review of 90 patients including two groups (HS group, n=45 versus TB group, n=45) of patients matched for their patient factors was conducted. Clinicopathologic factors of the patients and surgical outcomes such as the operation time, intraoperative bleeding, amount and duration of drain, hospital stay and complications were compared between two groups. Results: There were no significant difference between two groups regarding the clinicopathologic factors and short-term surgical outcomes. Conclusion: Thunderbeat and HS are both effective and safe for parotidectomy and SMG resection in variable benign disease of major salivary gland.

        Background and Objectives: Voice change after thyroidectomy may develop without injury of recurrent laryngeal nerve. Psychogenic or emotional factors related to voice change after thyroidectomy has been rarely studied. In this study, we sought to analyze the impact of anxiety on early state of post-thyroidectomy voice change. Materials and Methods: We made a retrospective chart review of 36 patients who underwent thyroidectomy for papillary thyroid carcinoma and voice exam before surgery, 2 weeks after and 1 month after surgery. All patients included in the study answered a questionnaire for State-Trait Anxiety Inventory ; STAI-KYZ (form Korean YZ). Clinico-pathologic factors and parameters of voice analysis were reviewed to analyze correlation to the anxiety index. Results: No differences were identified between clinicopathologic factors and preoperative parameters of voice analysis between patients with higher and lower level of anxiety. Noise to harmonic ratio (NHR) was higher in those patients with higher level of anxiety, 2 weeks after surgery (p=0.043). However, none of the parameters showed any difference 1 month later. Conclusion: With limited number of patients and short period of follow up, significant impact of preoperative anxiety on postoperative voice change after thyroidectomy could not be identified in this preliminary study.
