ABSTRACT
Objective To summerize our experience in the diagnosis and treatment of pancreatic cystic neoplasms.Methods A retrospective analysis was conducted on the clinical data of 126 patients with pancreatic cystic neoplasms seen between January 2003 and December 2012 in the Fuzhou General Hospital.Results There was no special clinical manifestation in this series of 126 patients with pancreatic cystic neoplasms.The diagnostic accuracies of ultrasound,CT and MRI were 90.8％ (109/120),93.4％ (114/122) and 96.3％ (103/107) respectively.Eighteen and ten patients were observed to have elevated serum CA19 9 and CEA respectively.One hundred and five patients received conventional open surgery,while 21 patients underwent laparoscopic operations.The operations in cluded enucleation of tumor (n=11),pancreatic segment resection (n=5),spleen preserving distal pancreatectomy (n=30),distal pancreatectomy (n=26),duodenum-preserving pancreatic head resection (n=4),pylorus-preserving Whipple resection (n=5),Whipple procedure (n=38),total pancre atectomy (n=2) and exploratory laparotomy and biopsy (n=5).The perioperative mortality rate was 0.8％ (1/126).Pancreatic fistula (B and C) occurred in 16 patients (12.7％,16/126),and postoperative hemorrhage (B and C) occurred in 9 patients (7.1％,9/126).One hundred and fourteen patients were followed up from 6 to 72 months (median 52.4 months).The five-year survival rates for all the pancreatic cystic neoplasms,non-invasive and invasive neoplasms were 80.5％,96.4％ and 40.7％ respectively.Conclusions Pancreatic cystic neoplasms are a rare subset of pancreatic tumor,being increasingly detected due to the widespread use of abdominal imaging and improved imaging techniques.Most of them are benign,but some are malignant or they have malignant transformation and metastatic potential.Patients with asymptomatic benign pancreatic cystic neoplasms,especially small size,are candidates for observation.Patients with clinical symptoms or having a high suspicion of malignancy should be offered surgical resection.Non-invasive neoplasms should receive pancreatic preserving operations.Pancreatectomy plus regional lymph nodes dissection with or without combined resection of adjacent multi organs should be adopted for invasive neoplasms.
ABSTRACT
Objective To study the anatomy of the caudate lobe and to apply the knowledge in caudate lobe resection and piggyback liver transplantation. Methods Dissection of the caudate lobe was carried out in 35 fresh adult livers. Before dissection, the portal venous system was injected with barium sulfate emulsion to show the portal branches of the caudate lobe. Results The caudate lobe was shown to consiste of 3 portions: (1) the Spigelian lobe, the paracaval portion and the caudate process. The Spigelian lobe was pyramidal in shape with 3 faces, a peak and a base; (2) the paracaval portion was situated to the right and to the front of the vena cava; (3) the caudal process was the liver parenchyma between the hepatic hilum and the anterior aspect of the vena cava. Conclusions The entire caudate lobe is situated at the posterior part of the liver and it surrounds the vena cava. The key point in resecting the entire caudate lobe or in performing a piggyback liver transplantation is adequate mobilization and division of all the outflowing veins of the caudate lobe.
ABSTRACT
Objective To observe the effects of Wu-Yao,Da-Huang combination on severe acute pancreatitis gut barrier protection,and on the clinical treatment of severe acute pancreatitis.Methods In the past 10 months,45 casea of severe pancreatitis those treated in our department were randomly divided into 3 groups.group A:on the basis of conventional treatment of inhibiting trypsin secretion and anti-infection,50%magnesium sulfate 50 mL were insected via stomach tube,twice a day;group B:on the basis of conventional treatment,Da-Huang decoction 100 mL high retention enema,twice a day;group C:on the basis of conventional treatment were given by Wu-Yao decoction 50 mL.as well as 100 mL Da-Huang decoction enema,twice a day.Three groups were observed the release of abdominal distension,abdominal(bladder pressure measurement),ACAPHE-Ⅱ score,indicators of neutrophils(N),C-reactive protein(CRP),and the blood levels of D-lactic acid in 1,3,5,7,9 days etc.Results The abdomenal circumference,abdominal pressure,APACHE-Ⅱ score,N and other indicators of the three groups after treatment had the significantly different(P<0.05),with group C the most significant decrease,while no significant difference in CRP.Endotoxin content in three groups was significantly different(P<0.05),and each diminished with time(P<0.05).Conclusion Wu-Yao,Da-Huang combination on gut barrier dysfunction in severe acute pancreatitis showed synergistic protective effect.
