Evaluation de la formation des résidents en chirurgie générale et digestive en Tunisie

Introduction: De nombreux moyens sont mis à disposition des résidents en chirurgie générale et  digestive pour assurer leur formation théorique et pratique. Cependant, le niveau d'utilisation de ces différents outils et leur impact sur la formation des résidents n'ont jamais été évalués. L'objectif de notre étude était d'étudier l'état des lieux des moyens de formation utilisés par les résidents pour évaluer leurs degrés de satisfaction et leurs propositions en vue d'améliorer leur formation. Méthodes: Un questionnaire anonyme a été distribué aux résidents de chirurgie générale et digestive de l'année  2012-2013. Ce questionnaire portait sur les caractéristiques démographiques, les ressources   pédagogiques, ainsi que le cursus médical et universitaire. Une évaluation de la formation ainsi qu'un  recueil des propositions faites en vue d'améliorer leurs formations étaient réalisées.Résultats: Cinquante résidents sur 83 ont répondu au questionnaire. L'orientation de carrière la plus  fréquente était l'hospitalouniversitaire dans 70% des cas. La pratique quotidienne et l'internet étaient les deux ressources pédagogiques les plus utilisées. La formation chirurgicale était jugée satisfaisante par  seulement 10% des répondants. Parmi l'ensemble des propositions faites, l'apprentissage sur simulateurchirurgical, l'existence d'un ouvrage national de référence, et l'institution d'un tutorat par un chirurgien  senior recueillaient plus de 80% d'avis favorable.Conclusion: La majorité des résidents jugent leur formation non satisfaisante. Une meilleure information sur les ressources déjà existantes, un renforcement du compagnonnage et un accès plus large à un  apprentissage sur simulateur chirurgical permettraient de diminuer ce sentiment d'insatisfaction.Key words: Résidanat, chirurgie, pédagogie médicale, formation, recherch

Résection laparoscopique d’une duplication gastrique chez l’adulte: traitement avec succès pour une pathologie rare

Les duplications de l'appareil digestif sont les malformations congénitales rares qui peuvent toucher tout  l'appareil digestive depuis la bouche jusqu' à l'anus. Certaines duplications sont asymptomatiques et sont diagnostiqués dans la plupart des cas pendant l'enfance. La prise en charge de la duplication gastrique est essentiellement chirurgicale. Le traitement de choix est l'exérèse complète de la duplication gastrique. Les auteurs rapportent un cas inhabituel de duplication gastrique complètement reséquée par laparoscopie. A notre connaissance, ceci est le premier cas d'une duplication gastrique traitée avec succès par laparoscopie dans la littérature Tunisienne. La Résection laparoscopique peut être ajoutée à l'arsenal thérapeutique dans le traitement chirurgical de duplications du tube digestif.Key words: Duplication, estomac, diagnostic, endoscopi

Retrorectal Schwannomas: Atypical Presentation and Controversial Surgical Management

Schwannomas also known as neurilemomas are benign tumors. Retrorectal schwannomas are extremely rare, accounting for 1 to 5% of all schwannomas. They are mostly asymptomatic but may present with symptoms such as pelvic pain, back pain, lower extremities pain, or constipation. Physical examination is often poor. Imaging (CT, MRI) and fine needle biopsy can often help orient the diagnosis. The treatment of choice is monoblock resection of the mass. The prognosis is good. Recurrence has been reported especially after intralesional enucleation. We report a case of a 41-year-old male patient consulting for chronic low back pain eventually diagnosed with retrorectal schwannoma. We performed a surgical resection and the histological examination was consistent with the diagnosis of benign (ancient) schwannoma

Pulmonary Embolism as a Rare Complication of Liver Hydatid Cyst: Report of Two Cases

Hydatid cyst is a helminth infection. The rupture of a hepatic hydatid cyst in inferior vena cava is a rare and lethal complication. Pulmonary embolism is the commonest manifestation. The diagnosis of hydatid cyst is made by histopathological or serological examination, and imaging may suggest the probability of hydatid cyst. Surgical treatment should be performed with caution and always under vascular control. We present two cases of hydatid cyst ruptured into the inferior vena cava. The patients also presented with dyspnea, hemoptysis, and intermittent cough at the time of admission. This presentation will be accompanied by a brief review of the literature. The radiological findings suggested the diagnosis. The first patient had a fatal hydatid pulmonary embolism and death occurred on the second day of hospitalization. The second patient refused surgery. These cases also exemplify the clinical and radiographic findings as well as the management of this complication

Photocatalytic degradation of ethylbenzene in gas phase over N or NF doped TiO2 catalysts

TiO2 nanoparticles were synthesized via sol–gel method using different N or NF doping precursors. The prepared samples were characterized by UV–Vis-DR Spectroscopy (DRS), X-ray diffraction (XRD), N2 physisorption and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity was evaluated in the degradation of ethylbenzene in the gas phase at atmospheric pressure and room temperature. The results showed that nitrogen and fluorine were successfully doped in TiO2 leading to a clear narrowing of the band gap energy (red shift). This narrowing was especially observed for N–TiO2 (2.91 eV) when using urea as nitrogen precursor. The sample prepared with 4-fluorobenzyleamine as precursor showed the smallest pore size (around 10 nm) and crystallite size (about 12 nm) compared to the other prepared catalysts. Additionally, it showed the highest efficiency for the photocatalytic conversion of 1000 ppm ethylbenzene, reaching around 32% under UV light and 17% under visible ligh

A case report of abdominal wall hydatidosis: An uncommon location

Liver hydatid cyst fistulized in the abdominal wall is rare. The clinical symptoms were often misleading. It often poses a problem of seat diagnosis rather than a problem of its hydatid nature despite the great contribution of modern imagery. We reported this uncommon case to highlight the difficulties of preoperative diagnosis and a better operative approach. 46-year-old men consulted for right flank pain. The clinical exam revealed a right flank subcutaneous mass. An abdominal CT scan showed multicystic lesions on the right flank. The MRI showed multiple cystic lesions on the right flank with several endophytic and exophytic daughter cysts. The patient was operated on. A wide excision was adopted to remove all the cystic lesions. The postoperative follow-up was uneventful. Abdominal subcutaneous hydatid cysts cause a diagnostic problem and the treatment is controversial. Surgery remains the only curative treatment. It avoids the risk of complications such the fistula, infection, and rupture

A systematic review and meta-analysis of hernia sac management in laparoscopic groin hernia mesh repair: reduction or transection?

Abstract Background There is no consensus regarding hernia sac management during laparoscopic hernia repair, and this systematic review and meta-analysis aimed to compare the postoperative outcomes of sac reduction (RS) and sac transection (TS) during laparoscopic mesh hernia repair. Methods We conducted a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) 2020 and AMSTAR 2 (Assessing the Methodological Quality of Systematic Reviews) guidelines. We used the RevMan 5.4 statistical package from the Cochrane collaboration for meta-analysis. A random effects model was used. Results The literature search yielded six eligible studies including 2941 patients: 821 patients in the TS group and 2120 patients in the RS group. In the pooled analysis, the TS group was associated with a lower incidence of seroma (OR = 1.71; 95% CI [1.22, 2.39], p = 0.002) and shorter hospital stay (MD = -0.07; 95% CI [-0.12, -0.02], p = 0.008). There was no significant difference between the two groups in terms of morbidity (OR = 0.87; 95% CI [0.34, 2.19], p = 0.76), operative time (MD = -4.39; 95% CI [-13.62, 4.84], p = 0.35), recurrence (OR = 2.70; 95% CI [0.50, 14.50], p = 0.25), and Postoperative pain. Conclusions This meta-analysis showed that hernia sac transection is associated with a lower seroma rate and shorter hospital stay with similar morbidity, operative time, recurrence, and postoperative pain compared to the reduction of the hernia sac. Protocol The protocol was registered in PROSPERO with ID CRD42023391730
