- ItemTaking advantage of asynchronous digital feedback: development of an at‑home basic suture skills training program for undergraduate medical students that facilitates skills retention(2023) Belmar Riveros, Francisca; Gaete Dañobeitia, María Inés; Durán Espinoza, Valentina; Chelebifski Vargas, Slavka; Jarry Trujillo, Cristián; Ortiz Koh, Catalina; Escalona, Gabriel; Villagrán Gutiérrez, Ignacio Andrés; Alseidi, Adnan; Zamorano Rivera, Elga; Pimentel Muller, Fernando; Crovari Eulufi, Fernando; Varas Cohen, Julián; Pontificia Universidad Católica de Chile. Centro de Cirugía Experimental y Simulación. Departamento de Cirugía Digestiva; Pontificia Universidad Católica de Chile. Departamento de Cirugía DigestivaPurpose to date, there are no training programs for basic suturing that allow remote deliberate practice. This study seeks to evaluate the efectiveness of a basic suture skills training program and its 6-month skill retention applying unsupervised practice and remote digital feedback. Methods Fourth-year medical-student trainees reviewed instructional videos from a digital platform and performed unsu pervised practice as needed at their homes. When they felt competent, trainees uploaded a video of themselves practicing the skill. In<72 h, they received expert asynchronous digital feedback. The course had two theoretical stages and fve video-based assessments, where trainees performed diferent suturing exercises. For the assessment, a global (GRS) and specifc rating scale (SRS) were used, with a passing score of 20 points (max:25) and 15 (max:20), respectively. Results were compared to previously published work with in-person expert feedback (EF) and video-guided learning without feedback (VGL). A subgroup of trainees underwent a 6-month skills retention assessment. Results Two-hundred and forty-three trainees underwent the course between March and December 2021. A median GRS of 24 points was achieved in the fnal assessment, showing signifcantly higher scores (p<0.001) than EF and VGL (20.5 and 15.5, respectively). Thirty-seven trainees underwent a 6-month skills retention assessment, improving in GRS (23.38 vs 24.03, p value=0.06) and SRS (18.59 vs 19, p value=0.07). Conclusion It is feasible to teach basic suture skills to undergraduate medical students using an unsupervised training course with remote and asynchronous feedback through a digital platform. This methodology allows continuous training with the repetition of quality practice, personalized feedback, and skills retention at 6 months.
- ItemTransgastric repair of transfixing gastroesophageal junction gunshot wound: video case report(2021) Vela, Javier; Contreras, Caterina; Varas, Julián; Ottolino, Pablo; Ramos, Juan Pablo; Escalona, Gabriel; Díaz, Alfonso; Achurra, Pablo; Ceroni, MarcoAbstract Managing traumatic injuries of the gastroesophageal junction (GEJ) is infrequent due to associated lesions of adjacent highly vascularized organs. Its anatomical localization in the upper abdomen makes the repair challenging to perform. A stable 23-year-old male was presented at the emergency department with two thorax gunshot wounds. Computed tomography revealed air in the periesophageal space and right hemopneumothorax with no injury of the major vessels. A chest tube was placed and the patient was transferred hemodynamically stable to the operating. Abdominal exploration identified injuries to the left diaphragm; liver lateral segment; 1-cm transfixing perforation of the GEJ and right diaphragmatic pillar. Primary repair of the GEJ was performed and patched with a partial fundoplication. The diaphragm was repaired and the liver bleeding controlled. Finally, drains and a feeding jejunostomy were placed. The patient had an uneventful early postoperative course and was discharged home on the 12th postoperative day.
