Introduzione L’anastomosi del pancreas residuo con il tratto digestivo dopo duodenocefalopancreasectomia (DCP) rimane un aspetto critico nella gestione del paziente operato che può condizionare molteplici variabili che vanno dalla qualità di vita allo sviluppo di insufficienza pancreatica esocrina. Spesso la tecnica standard di pancreo-digiuno-anastomosi (PJ) viene sostituita dalla pancreo-gastro-anastomosi (PG), di più facile esecuzione e gravata da minori complicanze. Ad oggi non esiste nessuno studio a lungo termine di comparazione tra i due tipi di anastomosi. Materiali e Metodi. Lo studio è stato condotto su 31 pazienti operati di DCP per neoformazione pancreatica, papillare o per pseudotumor infiammatorio, dal 2001 al 2006. Tutti sono stati ospedalizzati e sottoposti a studi morfologici e di funzione. I parametri studiati sono stati il volume pancreatico ed il diametro del dotto pancreatico principale (MRI), la funzione esocrina del pancreas (grassi fecale, elastasi fecale e vitamina D) e la funzione endocrina. La qualità di vita e gli score sintomatologici sono stati valutati tramite il questionario EORTC QLQ-C30. E’ stata riportata la media ± 1 errore standard. La normalità della distribuzione è stata indagata mediante il test di Kolmogorov-Smirnov e la correlazione tra variabili indipendenti tramite test di Bravais-Pearson. Risultati. Sono stati studiati 31 pazienti, 15 con PG, 16 a PJ. Nessuna differenza è stata riscontrata in durata del follow-up, BMI, funzione endocrina, score sintomatologici e qualità di vita. La funzione esocrina del pancreas risulta più alterata dopo PG che dopo PJ (steatorrea 26.6±4.1 vs 18.2±3.6 g/die; FE-1 170.2±25.5 vs 121.4±6.7 μg/g). Vi è una netta riduzione di vitamina D (maggiore nelle PG rispetto alle PJ) (18.1±1.8 vs 23.2±3.1 ng/ml).La MRI ho mostrato una severa riduzione del volume pancreatico residuo (più basso nelle PG rispetto alle PJ 26±3.1 vs 36±4.1 ml), e un netto aumento di diametro del dotto pancreatico residuo dopo PG (4.6±0.92 vs PJ 2.4±0.18 mm), indice di pancreatite ostruttiva. Conclusioni. Dopo interventi di DCP una marcata riduzione sia del volume pancreatico residuo sia della capacità funzionale del pancreas rappresentano la regola, e portano quasi invariabilmente all’insorgenza di steatorrea; la qualità di vita, nel lungo termine, risulta pari a quella dei controlli; i sintomi digestivi suggestivi di malassorbimento o malnutrizione non differiscono da quanto osservato in una popolazione ambulatoriale “normale”; si osserva invece frequentemente un deficit importante di micronutrienti, quale la vitamina D; risulta importante la necessità di una terapia enzimatica sostitutiva in tutti i pazienti, indipendentemente dal corredo sintomatologico presentato.
Introduction. The anastomosis of the residual pancreas with digestive tract after pancreaticoduodenectomy (PD) is a critical aspect in the management of the surgical patient that can affect many variables ranging from the quality of life to the development of exocrine pancreatic insufficiency. The standard technique of pancreo-jejunal-anastomosis (PJ) is often replaced by pancreo-gastro-anastomosis (PG), more easy to perform and with fewer complications. There is no long-term study of comparison between the two types of anastomosis. Material and Methods. We evaluated 31 patients after duodeno-cefalo-pancreatectomy (DCP) for pancreatic tumor from 2001 to 2006. All were hospitalized and submitted to morphological and functional studies. We studied the pancreatic volume and the diameter of the main pancreatic duct (MRI), the exocrine function of the pancreas (fecal fat, fecal-elastase and vitamin D) and endocrine function. The quality of life was assessed using the EORTC QLQ-C30. It was reported the mean ± 1 standard error. The normality of the distribution was investigated by the Kolmogorov-Smirnov test and the correlation between independent variables by the Bravais-Pearson test. Results. We studied 31 patients (15 with PG and 16 PJ). No difference was found in the duration of follow-up, BMI, endocrine function, symptom scores and quality of life. The exocrine pancreatic function is worse after PG than after PJ (steatorrhea 26.6 ± 4.1 vs 18.2 ± 3.6 g/day; FE-1 170.2 ± 25.5 vs 121.4 ± 6.7 µg/g). There is a reduction of vitamin D (higher in PG compared to PJ) (18.1 ± 1.8 vs 23.2 ± 3.1 ng / ml). The MRI showed a severe reduction in the residual pancreatic volume (lower in PG than PJ: 26±3.1 vs 36±4.1 ml), and an increase in the diameter of the pancreatic duct after PG (4.6 ± 0.92 vs 2.4 ± PJ of 0.18 mm), indicative of obstructive pancreatitis. Conclusion. After DCP there is a marked reduction both of the residual pancreatic volume both of the functional capacity of the pancreas which lead to steatorrhea. In the long term no differences in quality of life was found between operated patients and controls. Digestive symptoms suggestive of malabsorption or malnutrition not differ from that observed in a "normal" population-patient. However there is frequently a lack of important micronutrients, such as vitamin D and all patients needed important enzyme replacement, regardless of the set of symptoms presented

Abstract
Introduction. The anastomosis of the residual pancreas with digestive tract after pancreaticoduodenectomy (PD) is a critical aspect in the management of the surgical patient that can affect many variables ranging from the quality of life to the development of exocrine pancreatic insufficiency. The standard technique of pancreo-jejunal-anastomosis (PJ) is often replaced by pancreo-gastro-anastomosis (PG), more easy to perform and with fewer complications. There is no long-term study of comparison between the two types of anastomosis. Material and Methods. We evaluated 31 patients after duodeno-cefalo-pancreatectomy (DCP) for pancreatic tumor from 2001 to 2006. All were hospitalized and submitted to morphological and functional studies.
