General surgery educational resources for Jordanian medical students.

Background: To outline the resources deemed most beneficial to medical students during their general surgery clerkship, as well as to examine their link to students' general surgery scores and the usage of artificial intelligence in general surgery study. Methods: A retrospective survey of Jordanian medical students from six universities was done between March and June 2023 using a 7-item questionnaire covering questions concerning general surgery study methods and scores. Descriptive statistics were used to evaluate demographic data. Chi-square is used to evaluate categorical data, with a P value <0.05 deemed significant. Results: The average age of respondents was 23.3 years, and 54.2 % of the respondents were females, 47.8 % were from Mutah University. Most students (48.2 %) relied on tutor lectures. Students who studied through instructor lectures had the highest grades (9 % excellent, 17 % very good), followed by students who studied using surgery textbooks (6.8 % and 14.6 %, respectively). The relationship between the study method and academic achievement was statistically significant (P < 0.05). Conclusions: Traditional face-to-face learning with instructor lectures and surgery textbooks is still the most efficient approach to attain the greatest scores. Medical students are still underutilizing artificial intelligence.

Single-Dose enoxaparin for portomesenteric venous thrombosis prophylaxis after sleeve gastrectomy.

Introduction: Portomesenteric venous thrombosis (PMVT) may complicate sleeve gastrectomy. We believe that single dose of enoxaparin postoperatively can reduce the risk of PMVT. Objective: The objective was to study the outcomes of enoxaparin single dose compared to other perioperative prophylactic doses in preventing PMVT. Methods: Participants included 590 patients who underwent laparoscopic sleeve gastrectomy (LSG). These retrospective cohort data were collected from patient medical charts after bariatric surgery. Patients were followed up in the close postoperative period and at 1, 3, 6, 12, and 18 months. Descriptive statistical analysis was carried out. The objective was to estimate the incidence of PMVT with postoperative single 40 mg subcutaneous enoxaparin prophylactic regimen. Results: From January 2017 to December 2021, 590 patients with obesity underwent LSG. Five patients developed PMVT with an estimate incidence of 0.85%. Three patients had unexplained tachycardia and three patients had postoperative bleeding. Conclusions: Single-dose enoxaparin 40 mg is an effective thrombosis prophylaxis without increasing risk of bleeding.

Résumé Introduction: La thrombose veineuse portomésentérique (TVPM) peut compliquer la gastrectomie en manchon. Nous pensons qu'une dose unique d'énoxaparine en postopératoire peut réduire le risque de PMVT. Objectif: L'objectif était d'étudier les résultats de la dose unique d'énoxaparine par rapport à d'autres doses prophylactiques périopératoires dans la prévention de la PMVT. Méthodes: Les participants comprenaient 590 patients ayant subi une gastrectomie laparoscopique en manchon (LSG). Ces données de cohorte rétrospectives ont été collectées à partir des dossiers médicaux des patients après une chirurgie bariatrique. Les patients ont été suivis dans la période postopératoire étroite et à 1, 3, 6, 12 et 18 mois. Une analyse statistique descriptive a été réalisée. L'objectif était d'estimer l'incidence de la PMVT avec un régime prophylactique postopératoire unique d'énoxaparine sous-cutanée de 40 mg. Résultats: De janvier 2017 à décembre 2021, 590 patients obèses ont subi une LSG. Cinq patients ont développé une PMVT avec une incidence estimée à 0,85 %. Trois patients présentaient une tachycardie inexpliquée et trois patients présentaient des hémorragies postopératoires. Conclusions: Une dose unique d'énoxaparine de 40 mg est une prophylaxie efficace contre la thrombose sans augmenter le risque de saignement. Mots-clés: Énoxaparine, gastrectomie laparoscopique en manchon, thrombose veineuse portomésentérique prophylaxie, thromboembolie veineuse.

One-Stage vs Two-Stage Laparoscopic Roux-en-Y Gastric Bypass in Obese Patients with Body Mass Index >55 Kg/m2; 5-YEAR FOLLOW UP.

BACKGROUND: Surgical strategies in patients with BMI > 55 kg/m2 are not well established. OBJECTIVES: The objective of this study is to compare the long term results and complications of 1- vs. 2-stage laparoscopic "Roux-en-Y″ gastric bypass (LRYGB) for patients with BMI > 55 kg/m2. METHODS: Retrospective review of the complications and outcomes, between January 2007 and January 2010, for patients with a BMI > 55 kg/m2 who underwent directly a LRYGB (1-stage) or a LRYGB as a 2nd stage of a laparoscopic sleeve gastrectomy (LSG). RESULTS: Twenty-four patients were enrolled (no patient was lost during the 5-year follow-up). In the 1-stage LRYGB group, two patients had grade II complications according to Clavien-Dindo classification. In the 2-stage LRYGB group, complications of the first and the second surgery were summed. There were no differences between the two groups despite being heterogenous (more men with a higher BMI in the 2-stage group). There was a statistically significant difference in the final BMI in 1-stage LRYGB group compared to the 2-stage LRYGB group (34.46 ± 6.29 vs. 40.40 ± 3.47; p = 0.01, respectively) and in percentage of excess of BMI loss (%EBMIL; 69.80 ± 19.96 vs. 54.54 ± 13.93; p = 0.04, respectively). CONCLUSIONS: In patients with a BMI > 55 kg/m2, both 1- and 2-stage LRYGB give good long-term results. If feasible, a 1-stage LRYGB obtains a better percentage of excess of BMI loss but if not possible, the strategy of initially performing a laparoscopic sleeve gastrectomy followed by a LRYGB is safe and there were no differences in complications.
