RESUMEN
Objective To explore the clinical characteristics of huge pancreatic pseudocysts and to evaluate the effect of different surgical treatments. Method We retrospectively analyzed the clinical data of 27 patients with huge pancreatic pseudocyst managed from Feb 1991 to Feb 2008. Result Among a total of 129 patients with pancreatic pseudocyst treated during this period of time,27 (20.9% ) patients were diagnosed as with huge pancreatic pseudocyst (diameter > 10cm). As to the etiology, 51.9% of the psudoeyst was caused by acute pancreatitis, 33.3% by pancreatic trauma and previous surgery, 11.1% by chronic pancreatitis. Pseudoeysts in the majority of cases(21/27)had a history less than 6 weeks. Upper GI obstruction complicated 30% cases (8/27). Imaging showed that all huge pancreatic pseudocysts were single. ERCP showed communication with the main pancreatic duct in 9 out of 11 cases. Nine cases underwent catheter drainage, 10 cases underwent cystogastrostomy,2 cases underwent endoscopic drainage of pancreatic pseudocyst via ERCP, 17 cases underwent Roux-en-Y cystojejunostomy including 11 cases in which other previous procedures failed. All 27 cases were finally cured. Conclusions Huge pancreatic pseudocyst might have unique clinical characteristics. Anatomical changes of main pancreatic duct were found in most cases under ERCP. The proper time and indication for surgical intervention might be different from minor pancreatic pseudocyst.
RESUMEN
Objective To appraise the safety and validity of early enteral nutrition on the course on treating severe acute pancreatitis(SAP).Methods The clinical data of 71 patients with SAP were analyzed retrospectively. The album, prealbumin, TNF-β,CD4/CD8,IgG were observed. All the patients were randomly divided into two groups: enteral nutrition(EN)group for 36 patients and total parenteral nutrition(TPN)group for 35 patients. Results Fourteen days after treatment,CD4/CD8 and IgG in EN group were significantly increased than those in TPN group(P＜0.05),and prealbumin level in EN group significantly elevated(P＜0.05)and was higher than that in TPN group(P＜0.05).After treatment,TNF-α level in EN group significantly depressed(P＜0.05)and was lower than that in TPN group(P＜0.05).Conclusion Early enteral nutrition is safe and valid, and can promote albumin synthesis and prealbumin levels to improve their nutrition in patients with SAP, and may build-up the barrier of enteric mucosa to prevent bacterial shift, reduce systemic inflammatory reaction and improve its prognosis.
