Anastomotic and rectal stump leaks are feared complications of colorectal surgery. Diverting stomas are commonly used to protect low rectal anastomoses but can have adverse effects. Studies have reported favorable outcomes for transanal drainage devices instead of diverting stomas. We describe our use of the Heald anal stent and its potential impact in reducing anastomotic or rectal stump leak after elective or emergency colorectal surgery. We performed a single-center retrospective analysis of patients in whom a Heald anal stent had been used to “protect” a colorectal anastomosis or a rectal stump, in an elective or emergency context, for benign and malignant pathology. Intraoperative and postoperative outcomes were reviewed using clinical and radiological records. The Heald anal stent was used in 93 patients over 4 years. Forty-six cases (49%) had a colorectal anastomosis, and 47 (51%) had an end stoma with a rectal stump. No anastomotic or rectal stump leaks were recorded. We recommend the Heald anal stent as a simple and affordable adjunct that may decrease anastomotic and rectal stump leak by reducing intraluminal pressure through drainage of fluid and gas.
The use of CANVAS LMS in remote academic EFL writing classes: Its benefits and limitations
조영상,Andrew Richards,Stuart Jones 한국교양교육학회 2023 교양교육연구 Vol.17 No.4
The purpose of this study is to explore how English instructors at a Korean university utilized the CANVAS learning management system (LMS) when teaching EFL academic writing classes online, and their perceptions of its effectiveness and limitations. Seventeen instructors working at a university located on the outskirts of Seoul participated. Data were collected through a survey questionnaire consisting of a combination of multiple choice, a 5-point Likert scale, and open ended questions, all of which were used as the primary data collection method. Data analysis was conducted using general qualitative analysis for the open ended questions and descriptive statistics for the multiple choice and 5-point Likert scale questions. The findings of the study indicate such tools and functions as Lecture Contents, Inbox, Announcements, Assignments, Learn Status, Assignment Comment, and Speed Grader were used frequently on CANVAS, which was also related to the instructors’ high levels of satisfaction with this LMS in the areas of sharing course content, managing a classroom (e.g., monitoring students’ learning activities and communicating with students), and administering assignments and exams. On the other hand, the instructors reported that they used such tools and functions as Collaborations and Discussion less on Canvas, which matched their relatively low satisfaction with CANVAS in writing related areas such as grading, giving feedback, sharing peer feedback, and doing collaborative writing activities. Administrational and educational implications of these findings are discussed.

Purpose: The traditional prone positioning of percutaneous nephrolithotomy (PCNL) is associated with various anesthetic and logistic difficulties. We aimed to compare the surgical outcomes of PCNLs performed using our modified supine position with those performed in the standard prone position. Materials and Methods: A prospective group of 236 renal units (224 patients) undergoing PCNL were included in this 2 site study: 160 were performed in the modified supine position were compared with 76 undergoing PCNL in the prone position. The outcomes of radiation dose, radiation time, stone free rate, body mass index (BMI), stone size, operative time, length of stay (LOS), in hospital and complications were compared. Chi-square and t-tests were used. Results: There were no significant differences in mean radiation time, radiation dose or stone size between the modified supine and prone groups. The supine group had a higher mean BMI (31 kg/m2 vs. 28 kg/m2, p=0.03), shorter mean surgical time (93 minutes vs. 123 minutes, p<0.001), shorter mean LOS (2 days vs. 3 days, p=0.005) and higher stone free rate (70% vs. 50%, p=0.005). There were no differences in septic or bleeding complications but the prone group had a higher rate of overall complications. Conclusions: Modified supine PCNL has significantly lower operative time, shorter LOS and higher stone-free rate compared with prone in our series, while remaining a safe procedure.
