Purpose: Adjuvant chemotherapy (aCT) in rectal cancer patients who have undergone curative resection after neoadjuvant chemoradiation (nCRT) is controversial. We aimed to investigate the benefits of using aCT and the clinical impact of completing aCT in ypstage 2 rectal cancer patients. Methods: We retrospectively reviewed clinicopathological data from patients who had undergone radical resection after nCRT between January 2006 and December 2012. In total, 152 patients with ypT3/4N0M0 rectal cancer were included. Of these patients, 139 initiated aCT, while 13 did not receive aCT (no-aCT). Among those who received aCT, 132 patients completed their planned cycles (aCT-completion) whereas 7 did not (aCT-incompletion). All patients received long-course chemoradiation; a 5-fluorouracil-based regimen was used for nCRT in most patients. The prognostic factors affecting disease-free survival (DFS) and overall survival (OS) were analyzed. Results: The median follow-up duration was 41 months. Demographic data did not differ significantly among the 3 groups. In multivariate analysis, open surgery, a tumor size >2 cm, retrieval of <12 lymph nodes, circumferential resection margin (CRM) positivity and aCT incompletion were independent prognostic factors for poor DFS. Old age (≥60 years), open surgery, CRM positivity, aCT incompletion, and lack of aCT initiation compared to aCT completion were independent prognostic factors for poor OS. Conclusion: In ypstage 2 rectal cancer patients, aCT after nCRT and total mesorectal excision affected both DFS and OS; however, only patients who completed planned aCT exhibited survival benefits. Therefore, improving patients’ compliance with the completion of aCT is desirable.
Step-wise learning of laparoscopic low anterior resection
박윤영,이강영 대한내시경복강경외과학회 2021 Journal of Minimally Invasive Surgery Vol.24 No.1
A primary goal of training is the development of one’s own procedure by self-learning, which can be facilitated by laparoscopic surgery owing to its recordable system. This video demonstrates laparoscopic low anterior resection for a 56-year-old male diagnosed with synchronous S-colon cancer and rectal cancer. The surgery was performed by a second-year fellow in the colorectal division under supervision.

본 연구에서는 18가지 향 계열의 후각 감성을 통하여 따뜻한 이미지의 향과 차가운 이미지의 향을 분석 하고, 퍼스널컬러 따뜻한 유형과 차가운 유형에 따른 향의 선호도를 분석하였다. 20대 이상 성인 중 향에 대한 전 문적 특성을 가진 30명을 대상으로 설문을 실시하였으며, 자료 분석은 SPSS V.28 통계 패키지 프로그램을 사용 하였다. 연구 결과 퍼스널컬러에 따른 향 선호도는 개인적인 요소에 따라 다르게 나타났으며, 향에 대한 형용사와 색채에 대한 형용사의 분포 영역이 중첩되어 후각과 색채 사이의 연상 작용이 확인되었다. 본 연구는 각자의 개성 을 중요시하는 이 시대에 퍼스널컬러에 어울리는 향 이미지를 체계화시키며, 향 선택을 위한 기초 자료를 제공함 에 의의를 지닌다. This study, scents of warm images and scents of cold images were analyzed through olfactory sensibility of 18 types of scents, and scent preference according to warm and cold personal color type was analyzed. A survey was conducted targeting 30 adults with professional characteristics about orientation among adults in their 20s or older, and SPSS V.28 statistical package program was used for data analysis. As a result of the study, fragrance preference according to personal color appeared differently according to individual factors, and the association between smell and color was confirmed by overlapping distribution areas of adjectives for fragrance and adjectives for color. This study has significance in systematizing scent images suitable for personal colors in this era when each person's individuality is important, and providing basic data for scent selection.
Safety of laparoscopic appendectomy for the management of acute appendicitis during pregnancy
박윤영 대한내시경복강경외과학회 2021 Journal of Minimally Invasive Surgery Vol.24 No.2
Laparoscopic appendectomy during pregnancy is widely accepted as a safe procedure in Korea, where the rate of laparoscopic surgery is high. Although the Society of American Gastrointestinal and Endoscopic Surgeons guideline currently mentions laparoscopic appendectomy as the treatment of choice for pregnant patients with appendicitis, some concerns arising from pneumoperitoneum during laparoscopic surgery exist in maternal postoperative and fetal outcomes. Further effort to provide firm evidence to clarify the safety of laparoscopic appendectomy during pregnancy is still needed.
