A cost-conscious establishment of a robotic abdominal wall reconstruction program in a publicly funded healthcare system.

PURPOSE: Despite reports of better short-term outcomes, the main criticism for the adoption of the robotic surgery platform for abdominal wall reconstruction (AWR) has been the associated cost, especially in countries with a publicly funded healthcare system such as Canada. We describe our experience in implementation of robotic AWR while ensuring cost-effectiveness. METHODS: This is a retrospective cohort analysis of all patients with ventral hernias ranging between 5 to 15 cm who underwent either open or robotic AWR between January 2020 to August 2022. We reviewed patient characteristics, operative time, post-operative length of stay (LOS), and average cost of surgery. RESULTS: 45 patients underwent open repair and 28 underwent robotic repair in the study period. There was no difference in major patient characteristics between the two groups. Operative time was shorter for open repairs (233.2 ± 96.6 min vs. 299.3 ± 71.8 min, p < 0.001). LOS was significantly longer for open repairs (5 days (interquartile range = 4-6) vs. 2 days (IQR = 1.75-3), p < 0.001) and there were significantly more patients who underwent robotic repair who left hospital in less than 3 days (13.3 vs. 64.3%, p < 0.001). The average overall hospital-based cost for each open repair was $26,952.18 when the cost for equipment, operative time, inpatient hospital stay, and epidural use are accounted for, compared to $17,447.40 for robotic repair ($9,504.78 saving per case). CONCLUSION: With proper selection of patients based on size of hernia, we demonstrate cost conscious adaptation of the robotic technology to AWR. Our future studies will continue to explore the benefits and limits of this approach in complex hernia repair.

Morbidity and mortality conferences in general surgery: a narrative systematic review.

Background: In medical and surgical departments around the world, morbidity and mortality conferences (MMC) serve dual roles: they are cornerstones of quality-improvement programs and provide timely opportunities for education within the urgent context of clinical care. Despite the widespread adoption of MMCs, adverse events and preventable errors remain high or incompletely characterized, and opportunities to learn from and adjust to these events are frequently lost. This review examines the published literature on strategies to improve surgical MMCs. Methods: We searched OVID Medline, PubMed, Embase and CENTRAL. We defined our combination of search terms using a PICO (population, intervention, comparison, outcome) model, focusing on the use of MMCs in general surgery. Results: The MMC literature focused on 5 themes: educational value, error analysis, case selection and representation, attendance and dissemination. Strategies used to increase educational value included limiting case presentation time to 15-20 minutes, mandatory brief literature reviews, increasing audience interaction, and standardizing presentations using a PowerPoint template or SBAR (situation, background, assessment, recommendation) format. Interventions to improve error analysis included focused discussion on causative factors and taxonomic error analysis. Case selection was improved by using an electronic clinical registry, such as the National Surgery Quality Improvement Program, to better capture incidence of morbidity and mortality. Attendance was improved with teleconferencing. Dissemination strategies included MMC newsletters, incorporating MMCs into plan-do-check-act cycles, and surgeon report cards. Conclusion: Greater standardization of best practices may increase the quality improvement and educational impact of MMCs and provide a baseline to measure the effect of new MMC format innovations on the clinical and educational performance of surgical systems.

Contexte: Dans les services de médecine et de chirurgie du monde entier, les conférences sur la morbidité et la mortalité (CMM) jouent 2 rôles : elles forment la pierre angulaire des programmes d'amélioration de la qualité de soins et fournissent l'occasion de faire de l'enseignement dans le contexte même des soins cliniques immédiats. Malgré la popularité grandissante des CMM, le nombre d'événements indésirables et d'erreurs évitables demeure élevé ou mal caractérisé et on perd beaucoup d'occasions d'apprendre de ces événements et d'apporter les changements qui s'imposent. La présente revue analyse la littérature publiée sur les stratégies d'amélioration des CMM en chirurgie. Méthodes: Nous avons interrogé OVID Medline, PubMed, Embase et CENTRAL. Nous avons défini nos combinaisons de mots clés à l'aide du modèle PICO (population, intervention, comparaison et résultat [outcome]), en mettant l'accent sur l'utilisation des CMM en chirurgie générale. Résultats: La littérature sur les CMM se concentrait sur 5 thèmes : valeur didactique, analyse des erreurs, sélection et représentation des cas, participation et dissémination. Les stratégies utilisées pour accroître la valeur didactique incluaient limiter la durée des présentations de cas à 15­20 minutes, présenter de brèves revues de la littérature, favoriser les interactions avec l'auditoire et standardiser les présentations au moyen de modèles PowerPoint ou SBAR (situation, background, assessment, recommendation). Les interventions visant à améliorer l'analyse des erreurs incluaient une discussion sur les facteurs causaux et l'analyse des erreurs taxonomiques. La sélection des cas a été améliorée au moyen d'un registre clinique électronique comme le National Surgery Quality Improvement Program, pour mieux suivre l'incidence de la morbidité et de la mortalité. Les systèmes de téléconférences ont amélioré la participation. Parmi les stratégies de dissémination, mentionnons les bulletins sur les CMM, leur intégration aux cycles planifier/faire/vérifier/agir et les relevés de notes des chirurgiens. Conclusion: Une meilleure standardisation des pratiques optimales pourrait améliorer davantage la qualité des soins et augmenter l'impact didactique des CMM en plus d'offrir une base de référence pour mesurer l'effet des nouvelles mesures appliquées aux CMM sur le rendement clinique et didactique des systèmes chirurgicaux.

Fluorescent cholangiography in laparoscopic cholecystectomy: the initial Canadian experience.

BACKGROUND: Bile duct injury remains a worrisome complication of laparoscopic cholecystectomy. Indocyanine Green (ICG) fluorescent cholangiography (FC) is a new approach that facilitates real-time intraoperative identification of biliary anatomy. This technology is hoped to improve the safety of dissection within Calot's triangle. METHOD: Demographics, intraoperative details, and subjective surgeon data were recorded for elective cholecystectomy cases involving ICG. Goals were to identify rates of bile duct identification, and assess the perceived benefit of the device. RESULTS: ICG was used in 12 biliary cases in Canada. Visualization rates of the cystic and common bile ducts were 100% and 83%, respectively. Also, 83% of surgeons felt that FC incorporated smoothly into the operation. No complications have been related to the technology. CONCLUSIONS: FC allows noninvasive real-time visualization of the extrahepatic biliary tree. This novel technique has received positive feedback in its initial Canadian use and will likely be a durable adjunct for minimally invasive surgery.

Rigid vs articulating instrumentation for task completion in single-port surgery.

BACKGROUND: Single-port access surgery (SPA) may provide benefits but there is a steep learning curve. We compare traditional in-line instruments with articulating instruments. METHODS: Fundamentals of laparoscopic surgery peg transfer task was performed using a 3-port approach or SPA device. Standard rigid instrumentation was compared with articulating instrumentation. RESULTS: Twenty surgeons completed all tasks. Average time using a conventional approach was shorter than SPA (144 ± 54 vs 198 ± 74 seconds, P < .001). Articulating instruments required longer procedural time than rigid instrumentation (201 ± 66 vs 141 ± 58 seconds, P < .001). In the conventional model, task time was lower with rigid instruments than with articulating instruments (108 vs 179 seconds, P < .001). Task time in the SPA model was lower with rigid instruments (173 vs 223 seconds, P =.013). CONCLUSIONS: All tasks required longer time to complete in SPA when compared with a conventional approach. Articulating instruments have an increased benefit in SPA surgery.

Using three-dimensional laparoscopy as a novel training tool for novice trainees compared with two-dimensional laparoscopy.

BACKGROUND: Laparoscopic skills training is an essential component of general surgery training. This study proposes the use of three-dimensional (3D) laparoscopy as the initial training tool for beginners to shorten the learning curve. METHODS: This study evaluates the surgical performance and subjective experience of junior and senior trainees with 3D versus two-dimensional laparoscopy. Peg transfer task was used as the objective time measurement. A subjective evaluation of the 2 systems using a questionnaire was also used. RESULTS: The mean difference in the juniors was 16.33 seconds, while in the seniors it was only 3.46 seconds (P = .036). The time difference between groups was much smaller in the 3D than the two-dimensional (P = .14 vs .02) laparoscopy. In the subjective evaluation, the novice group also scored significantly higher for the 3D system in the bimanual dexterity category (P = .004, .007). CONCLUSION: Our study demonstrates the feasibility of using 3D laparoscopy for laparoscopic skills training in novices.

Outcomes of the adjustable gastric band in a publicly funded obesity program.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is considered a safe and effective treatment for severe obesity and obesity-related comorbidities. We sought to examine the outcome of LAGB delivered through a Canadian publicly funded obesity program. METHODS: We retrospectively analysed the cases of patients who underwent LAGB within a comprehensive, multidisciplinary, publically funded obesity program. RESULTS: A total of 178 patients underwent LAGB. Mean percentage total body weight loss at 1, 2 and 3 years was 15.8%, 20.7% and 20.3%, respectively. The most common short-term complication was postoperative nausea (19%). The medium-term complications included band migration (5.6%) and port site complications, band leakage and incisional hernia at 1% each. The reoperation rate was 4.5%. The mean surgery duration was 56 minutes and the mean length of stay was 1.4 days. The average numbers of clinic visits and band adjustments were highest in the first year. The most common investigation for postoperative symptoms was fluoroscopy (86%). An outcome comparison between the 2 generations of the REALIZE gastric band was inconclusive, requiring further data collection. CONCLUSION: Publicly funded LAGB results in effective weight loss and acceptable safety over the short term. Our patients may represent a distinct population that differs from that in the private system. Long-term data are necessary to determine the cost-effectiveness of this important surgical option for severe obesity.

CONTEXTE: L'anneau gastrique ajustable posé par laparoscopie (AGAL) est considéré comme un traitement sécuritaire et efficace contre l'obésité sévère et les comorbidités connexes. Nous avons cherché à analyser le résultat de la pose d'un AGAL réalisée dans le cadre d'un programme public de lutte contre l'obésité au Canada. MÉTHODES: Nous avons analysé de façon rétrospective les cas de patients qui ont reçu un AGAL dans le contexte d'un programme intégré et multidisciplinaire de lutte contre l'obésité financé par le secteur public. RÉSULTANTS: Au total, 178 patients ont reçu un AGAL. La perte procentuelle moyenne totale de masse corporelle à 1, 2 et 3 ans s'est établie à 15,8 %, 20,7 % et 20,3 % respectivement. Les nausées postopératoires ont constitué la complication à court terme la plus fréquente (19 %). Les complications à moyen terme ont inclus le déplacement de l'anneau (5,6 %) et des complications du côté porte, la fuite au niveau de l'anneau et une hernie à celui de l'incision : elles ont atteint 1 % dans chaque cas. Le taux de répétition de l'intervention a atteint 4,5 %. L'intervention chirurgicale a duré en moyenne 56 minutes et le séjour moyen 1,4 jours. Le nombre moyen de visites à la clinique et celui des rajustements de l'anneau étaient les plus élevés au cours de la première année. Les symptômes postopératoires sont examinés le plus souvent par fluoroscopie (86 %). Une comparaison des résultats entre les 2 générations de l'anneau gastrique REALIZE n'a pas été concluante, ce qui oblige à réunir d'autres données. CONCLUSIONS: La pose d'un AGAL financée par le secteur public entraîne une perte de poids efficace et offre une sécurité acceptable à court terme. Nos patients peuvent représenter une population distincte qui diffère de celle du secteur privé. Il faut des données à long terme pour déterminer la rentabilité de cette option chirurgicale importante en cas d'obésité sévère.

The process of treating pediatric appendicitis.

BACKGROUND: A large service and distant geographical area can make the process of diagnosing and treating appendicitis a challenge. METHODS: Hospital records of children treated for appendicitis between 2007 and 2009 were retrospectively analyzed, including time from emergency (ER) to operating room (OR), diagnostic imaging (DI) utilization, preoperative antibiotic usage, operating time, length of stay (LOS), and perforation rate. RESULTS: The perforation rate was 34%, with longer LOS. Transfer time to the children's hospital between ER inside and outside the city was not different. ER to OR time was significantly shorter for patients assessed at the children's hospital directly. Ultrasound remained the most used DI modality (55%). Preoperative antibiotics were only fully administered in 42% of the cases. CONCLUSION: A clinical pathway for pediatric appendicitis may address the challenges of the process of pre-ER, ER to OR, and OR care to maintain an acceptable perforation rate.
