Cholécystectomie laparoscopique ambulatoire: première expérience en Tunisie

Introduction: La cholécystectomie laparoscopique est le gold standard de la prise en charge des calculs vésiculaires symptomatiques. Il existe une importante controverse quant au fait de savoir si elle devrait être pratiquée en chirurgie ambulatoire ou dans le cadre d'une chirurgie avec hospitalisation d'une nuit pour ce qui concerne la sécurité des patients. Le but du travail est d’évaluer l'impact de la cholécystectomie laparoscopique en chirurgie ambulatoire versus en chirurgie avec hospitalisation d'une nuit sur les critères de jugement axés sur le patient, tels que la mortalité, les graves événements indésirables et la qualité de vie. Méthodes: Il s’agit d’une étude transversale descriptive réalisée au sein du service de chirurgie générale de l’hôpital Habib Thameur, sur la période allant de Mai 2009 à Février 2010. Cette étude porte sur 67 malades porteurs d’une lithiase vésiculaire symptomatique ayant eu une cholécystectomie laparoscopique en ambulatoire (CLA). Étaient exclus de l’étude: les malades ASA III et IV, les diabétiques sous sulfamides ou sous insuline, les grands obèses, les malades de plus de 65 ans et moins de 18 ans, ceux avec un antécédent de chirurgie abdominale majeure, les malades suspects d’une lithiase de la voie biliaire principale, d’une cholécystite aiguë ou d’une pancréatite. Pour être traité par CLA, le malade devait résider à moins de 50 km de l’hôpital, et avoir la possibilité d’une présence adulte à ses côtés. Résultats: Dix-sept patients étaient inclus puis exclus de notre étude devant la découverte per opératoire de signes de cholécystite aigue ou devant des difficultés de dissection amenant le chirurgien à mettre un drain de Redon en sous hépatique en fin d’intervention. Finalement, 50 patients ont été retenus: 7 hommes et 43 femmes d’âge moyen de 48 ans. L’intervention se déroulait selon les modalités habituelles. A la sortie de la salle de réveil, le patient était dirigé en secteur ambulatoire où une alimentation liquide était autorisée. Le malade était revu avant 19 h et la sortie décidée si une analgésie orale était possible, si une alimentation liquide était tolérée, s’il n’existait aucun trouble de la diurèse, et si le patient acceptait un retour à domicile avec un traitement antalgique et anti-inflammatoire à la demande. Trente neuf patients (78%) ont quitté l’hôpital et 11 ont été gardés. L’âge > à 45 ans, la durée de l’anesthésie > à 70 minutes et la fatigue post opératoire ont été identifié comme facteur de risque de sorties ratées. Aucune réadmission n’a été observée. Les patients qui ont pu être mis sortants ont été satisfaits du protocole de prise en charge avec des réponses majoritairement de type excellent et bon (94%). Conclusion: La chirurgie ambulatoire semble tout aussi sûre que la chirurgie avec hospitalisation d'une nuit dans la cholécystectomie laparoscopique avec un faible taux de complication et de réadmission chez des malades sélectionnés, et avec une réduction du coût de l’intervention

Ultrasound Modality in the Evaluation and Management of Gallbladder Polyps

Gallbladder polyps (GBP) are defined as developed masses inside the wall of the gallbladder; most of them (90%) are nontumor lesions. Abdominal ultrasound is the main and the first line radiological modality for their diagnosis and their risk lamination. We conducted a 12 year retrospective study between 2009 and 2020, which included patients who had preoperative transabdominal ultrasonography showing gallbladder polyps and had undergone cholecystectomy, and for whom postoperative pathology results were available, as well as patients who had at least one polyp discovered on the histopathological exam and who were not determined preoperatively. A total of 70 patients were identified. Preoperative diagnosis of vesicular polyp by ultrasound was carried in 82.9% of patients. The number of ultrasounds performed per person was 1.2 ± 0.47. The polyps’ size in mm was on average 6.14 ± 2.6 with extremes between 3 and 13 mm. On anatomopathological examination, a polyp was objectified in 33.3% of cases. In our series, abdominal ultrasound had a low sensitivity at 36.4%. We aim to provide the accuracy of abdominal ultrasound for the diagnosis of GBP, as a low-cost modality, and to evaluate the concordance of preoperative ultrasound imaging with postoperative pathology

EMERGENCY SURGERY FOR OBSTRUCTING COLON CANCER: MORBIDITY AND RISK FACTORS OF EARLY POSTOPERATIVE MORTALITY – A COHORT STUDY OF 118 CASES

ABSTRACT BACKGROUND: Occlusion is the most common complication of colon cancer. Surgical treatment is associated with the highest morbidity and mortality rate (10–27%) and has the worst prognosis. It is necessary for immediate management, avoiding colic perforation and peritonitis. The increase in mortality in emergency colon cancer surgery is multifactorial. AIMS: The aim of this study was to identify the risk factors for early postoperative mortality that highlights the therapeutic strategy in the management of obstructive colon cancer. METHODS: A retrospective study was performed on patients admitted from 2008 to 2020 at the Department of General Surgery due to obstructive colon cancer and operated on as an emergency (within 24 h of admission). RESULTS: In all, 118 patients with colon cancer were operated, and the early postoperative mortality was 10.2%. The univariate analysis highlighted that the American Society of Anesthesiology score III or IV, perforation tumor, one postoperative complication, and two simultaneous postoperative complications were considered significant risk factors for early postoperative mortality after emergent surgery. Multivariate analysis showed that only tumor perforation and the occurrence of two postoperative complications were significant risk factors. CONCLUSION: This study showed that postoperative complication is the leading cause of early postoperative mortality after emergency surgery for obstructive colon cancer. Optimizing the postoperative management of these higher risk patients is still necessary and may reduce the mortality rate

Comparison between signet-ring cell carcinoma and non-signet-ring cell carcinoma of the stomach: clinicopathological parameters, epidemiological data, outcome, and prognosis—a cohort study of 123 patients from a non-endemic country

Abstract Background Signet-ring cell carcinoma of the stomach (SRCC) is a particular gastric cancer entity. Its incidence is increasing. Its diagnosis is pathological; it corresponds to adenocarcinoma with a majority of signet-ring cells component (> 50%). These histological features give it its aggressiveness characteristics. This has repercussions on the prognostic level and implications for the alternatives of therapy, especially since some authors suggest a potential chemoresistance. This survey aimed to identify the epidemiological, pathological, therapeutic, and prognostic characteristics of SRCC as a separate disease entity. Methods This was a retrospective study of 123 patients admitted for gastric adenocarcinoma to Habib Thameur Hospital in Tunis over 11 years from January 2006 to December 2016. A comparative study was performed between 2 groups: the SRCC group with 62 patients and the non-SRCC (non-signet-ring cell carcinoma of the stomach) with 61 patients. Results The prevalence of SRCC in our series was 50%. SRCC affected significantly younger patients (55 vs 62 years; p = 0.004). The infiltrative character was more common in SRCC tumors (30.6 vs 14.8%; p = 0.060), whereas the budding character was more often noted in non-SRCC tumors (78.7 vs 58.1%; p = 0.039). There was no significant difference in tumor localization between both groups. Linitis plastica was noted in 14 patients with SRCC against a single patient with non-SRCC (p = 0.001). The tumor size was more important in the non-SRCC group (6.84 vs 6.39 cm; p = 0.551). Peritoneal carcinomatosis was noted in 4.3% of cases in the SRCC group versus 2.2% of cases in the NSRCC group (p = 0.570). Total gastrectomy was more often performed in the SRCC group (87 vs 56%; p = 0.001). Resection was more often curative in the non-SRCC group (84.4 vs 78.3%; p = 0.063). Postoperative chemotherapy was more commonly indicated in the SRCC group (67.4 vs 53.3%; p = 0.339). Tumor recurrence was more common in the non-SRCC group (35.7 vs 32%; p = 0.776). The most common type of recurrence was peritoneal carcinomatosis in the SRCC group (62.5%) and hepatic metastasis in the non-SRCC group (60%; p = 0.096). The overall 5-year survival in the SRCC group was lower than in the non-SRCC group, with no statistically significant difference (47.1 vs 51.5%; p = 0.715). The overall survival was more important for SRCC in early cancer (100 vs 80%; p = 0.408), whereas it was higher for non-SRCC in advanced cancer (48.1 vs 41.9%; p = 0.635). Conclusion Apart from its epidemiological and pathological features, SRCC seems to have a worse prognosis. Indeed, it is diagnosed at a more advanced stage and has a worse prognosis in advanced cancer than non-SRCC. It is therefore to be considered as a particular entity of gastric adenocarcinoma requiring a specific therapeutic protocol where the place of chemotherapy remains to be more investigated
