Results of vascular resections during pancreatectomy from two European centres: an analysis of survival and disease-free survival explicative factors
AbstractObjectives. The object of our study was to report on the experience with vascular resections at pancreatectomy in two European specialist hepatopancreatobiliary centres and evaluate outcome and prognostic factors. Patients and methods. From 1989 to 2002, 45 patients (21 men, 24 women) underwent pancreatectomy for a pancreatic mass: Whipple's procedure (n= 33), total pancreatectomy (n= 10) or left splenopancreatectomy (n= 2), along with a vascular resection, i.e. venous (n= 39), arterial (n= 1) or venous + arterial (n= 5). Results. Operative mortality was nil, postoperative mortality was 2.2% (n= 1); 34 patients had an uneventful postoperative course. Reoperations were performed for portal vein thromobosis (n= 1), pancreatic leak (n= 1), gastric outlet syndrome (n= 1) and gastrointestinal bleeding (n= 1). In all, 43 patients had cancer on pathology examination, with retropancreatic invasion in 72% and lymph node extension in 62.8%. Resection was R0 in 21 cases. Vessel wall invasion was present in 13 cases and 19 had perivascular invasion. Disease-free survival (DFS) at 1, 2 and 3 years was 36.0%, 15.0% and 12.0%, respectively. Median DFS length was 8.7 months (95% CI: 7.2; 10.2). Overall survival rates were 56.6%, 28.9% and 19.2%, respectively. Median survival length was 14.2 months (95% CI: 9.8; 18.6). A multivariate analysis of prognostic variables identified tumour location (other than head of pancreas), neoadjuvant chemotherapy and advanced disease stage as adverse factors for DFS. Conclusion. Survival and DFS rates of these patients are comparable to those without vascular resection. Tumour localization, tumour stage, neoadjuvant treatment and tumour recurrence are explanatory variables of survival. Tumour localization, tumour stage and neoadjuvant treatment were explanatory variables for DFS. However, the type and extent of vascular resections as well as vessel wall invasion does not affect survival and DFS
Les diverticules de l'oesophage : aspects chirurgicaux
Il demeure tout à fait classique de distinguer les diverticules de l'oesophage selon leur hauteur, en diverticules supérieurs, pharygo-oesophagiens, et diverticules inférieurs épiphréniques. Leur origine est liée à des phénomènes de pulsion. Les diverticules para-bronchiques moyens, de traction, s'opposent tout à fait aux précédents. Ils représentent moins de 25 % des cas. Ils sont peu chirurgicaux. A partir d'une série de 45 cas de diverticules pharyngo-oesophagiens et épiphréniques, comparée à l'étude multicentrique du G.E.E.M.O, et aux données de la littérature, nous essayerons de dégager les caractéristiques purement chirurgicales de cette affection
Les hémorragies des sigmoïdites aiguës
Les épisodes hémorragiques ne sont pas exceptionnels au cours de la diverticulose sigmoïdienne (de l'ordre de 15 à 20% des cas), mais il est beaucoup plus rare qu'ils conduisent à une intervention d'urgence pour hémostase. Nous ferons référence aux séries de la littérature les plus récentes et à deux séries lyonnaises publiées récemment : P. Maillet : 110 cas; Janody : 78 cas opérés en urgence
Le reflux biliaire duodéno-gastrique et gastro-œsophagien
This study reviews current data regarding duodenogastric and gastroesophageal bile reflux-pathophysiology, clinical presentation, methods of diagnosis (namely, 24-hour intraluminal bile monitoring) and therapeutic management. Duodenogastric reflux (DGR) consists of retrograde passage of alkaline duodenal contents into the stomach; it may occur due to antroduodenal motility disorder (primary DGR) or may arise following surgical alteration of gastoduodenal anatomy or because of biliary pathology (secondary DGR). Pathologic DGR may generate symptoms of epigastric pain, nausea, and bilious vomiting.
In patients with concomitant gastroesophageal reflux, the backwash of duodenal content into the lower esophagus can cause mixed (alkaline and acid) reflux esophagitis, and lead, in turn, to esophageal mucosal damage such as Barrett's metaplasia and adenocarcinoma. The treatment of DGR is difficult, non-specific, and relatively ineffective in controlling symptoms. Proton pump inhibitors decrease the upstream effects of DGR on the esophagus by decreasing the volume of secretions; promotility agents diminish gastric exposure to duodenal secretions by improving gastric emptying. In patients with severe reflux resistant to medical therapy, a duodenal diversion operation such as the duodenal switch procedure may be indicated
