Le traitement chirurgical des adénocarcinomes de la jonction oesogastrique: Expérience marocaine à travers une série de 149 cas

Introduction: L'incidence du cancer de la Jonction oesogastrique (JOG) ne cesse d'augmenter depuis les deux dernières décades aussi bien dans les pays industrialisés que dans les pays en voie de développement notamment le Maroc. Le rapprochement sur le plan étiopathogénique des adénocarcinomes (ADK) du cardia et ceux du bas oesophage reste un sujet de controverse posant le problème du choix thérapeutique chirurgical, notamment l’étendu de la résection. Le but de ce travail est de dresser le profil épidémiologique des patients opérés pour un ADK du cardia et analyser les gestes chirurgicaux réalisés par l’équipe chirurgicale A du centre hospitalier universitaire IBN SINA à Rabat à travers une série de 149 cas. Méthodes: Il s'agit d'une étude rétrospective ayant intéressé les malades opérés pour un ADK de la JOG sur une période de 15 années (1990-2004) en chirurgie A du CHU IBN SINA à Rabat. Résultats: 149 cas d'ADK de la JOG ont été retenus. L'âge moyen était de 55 ans, 76% étaient de sexe masculin avec un sex-ratio de 3/1. Les signes cliniques les plus fréquemment observés sont la dysphagie (70%), les douleurs épigastriques (67%) et le reflux gastro-oesophagien (15.5%). La notion de tabagisme n’a été rapportée que chez 20% des cas et l'oesophage de barret chez 10% des patients. Le type I de Siewert a concerné 65 cas (43.5%), le type II 40 cas (27 %), et le type III 44 cas (29.5%). Dans le type I une oesophagectomie transhiatale a été proposée, alors que les type II et III ont été traité comme un cancer de l'estomac par une gastrectomie totale. Les suites opératoires étaient simples chez 80 % des patients, la mortalité globale était de 8.5%. Conclusion: L’oesophagectomie par voie transhiatale chez les patients fragiles avec un ADK de la JOG de type I permet des résultats carcinologiques satisfaisants avec réduction de la morbidité postopératoire par rapport à la voie transthoracique. La gastrectomie totale est le traitement de choix pour les types III, alors que le débat est toujours ouvert quant à la meilleure stratégie chirurgicale pour la prise en charge des tumeurs de type II.Key words: Cardia, adénocarcinome, Siewert, chirurgie, Maro

Hémangiome intestinal: une cause inhabituelle d’hémorragie digestive inexpliquée, rapport d’un cas

Les hémangiomes de l'intestin grêle (HG) sont des tumeurs bénignes et rares du tube digestif, parfois  responsables d'hémorragie digestive. Le diagnostic positif de ces lésions est souvent difficile mais rendu plus aisé grâce à l’avènement de la vidéo capsule endoscopique (VCE) , le traitement est essentiellement  chirurgical. Nous rapportons une nouvelle observation d'un hémangiome caverneux du jéjunum révélé par une hémorragie digestive récidivante et diagnostiqué par VCE et nous discutons l’apport de cet examen dans la  prise en charge de l’hémorragie digestive inexpliquée tout en la comparant aux autres explorations actuellement disponibles.Key words: Hémangiome, intestin, vidéo capsule, hémorragie inexpliqué

Predictive model of biliocystic communication in liver hydatid cysts using classification and regression tree analysis

<p>Abstract</p> <p>Background</p> <p>Incidence of liver hydatid cyst (LHC) rupture ranged 15%-40% of all cases and most of them concern the bile duct tree. Patients with biliocystic communication (BCC) had specific clinic and therapeutic aspect. The purpose of this study was to determine witch patients with LHC may develop BCC using classification and regression tree (CART) analysis</p> <p>Methods</p> <p>A retrospective study of 672 patients with liver hydatid cyst treated at the surgery department "A" at Ibn Sina University Hospital, Rabat Morocco. Four-teen risk factors for BCC occurrence were entered into CART analysis to build an algorithm that can predict at the best way the occurrence of BCC.</p> <p>Results</p> <p><b>I</b>ncidence of BCC was 24.5%. Subgroups with high risk were patients with jaundice and thick pericyst risk at 73.2% and patients with thick pericyst, with no jaundice 36.5 years and younger with no past history of LHC risk at 40.5%. Our developed CART model has sensitivity at 39.6%, specificity at 93.3%, positive predictive value at 65.6%, a negative predictive value at 82.6% and accuracy of good classification at 80.1%. Discriminating ability of the model was good 82%.</p> <p>Conclusion</p> <p>we developed a simple classification tool to identify LHC patients with high risk BCC during a routine clinic visit (only on clinical history and examination followed by an ultrasonography). Predictive factors were based on pericyst aspect, jaundice, age, past history of liver hydatidosis and morphological Gharbi cyst aspect. We think that this classification can be useful with efficacy to direct patients at appropriated medical struct's.</p

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was USD 92 492 million using approach 1 and USD 73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was USD 95 004 million using approach 1 and USD 75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially.publishedVersio

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy

Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

Primary paraduodenal tuberculosis in its pseudotumoral form: A case report and review of the literature

Abdominal tuberculosis presents with nonspecific clinical and radiological features, often leading to diagnostic and therapeutic delays. Retroperitoneal pseudo-tumoral tuberculosis is a rare radio-clinical entity, characterized by its atypical and confusing symptomatology. We present the case of a 48-year-old male patient with no significant medical history, who was admitted to our department with a right retroperitoneal tumor presented as right renal colic due to compression of the lumbar ureter. Initially misdiagnosed as a gastrointestinal stromal tumor (GIST) of the lower duodenal angle, the patient underwent duodenal wedge resection, right hemicolectomy, and resection of the right lumbar ureter. Pathological examination of the surgical specimen confirmed follicular tuberculosis. The patient was subsequently treated with antitubercular drugs for 6 months with a good follow-up. Retroperitoneal pseudo-tumoral tuberculosis exhibits a polymorphic and nonspecific clinical presentation in our setting, highlighting the importance of early endoscopic or image-guided biopsies to prevent unnecessary surgical interventions
