Objective To summarize some problems about the management of acute pancreatic pseuclocyst (PPC) by CT guided percutaneous drainage (PCD).Methods The recent domestic and foreign literatures were reviewed in order to explore the research advancement, such as indication, applied time, technique skill, complication and curative effect by CT guided PCD. Results This operation could be early performed in patients with acute PPC, preventing and decreasing the incidence of possible complications resulted from the traditional long-term observation and waiting. The technique skill of operation was easy with low incidence of complications and the effect was good. Combined use of somatostatin might shorten the treatment time. Some patients could be postoperatively managed in out-patient, thus the expense could be cut down. Conclusions CT guided PCD is a minimally invasive operation and is easy to perform with high effective rate and low incidence of complications and low cost. Reasonable selection of the indications and improvement of equipments and operation techniques may be helpful to improve the curative effect. The extended application of this operation is advised.
Objective To explore the value of CT guided percutaneous puncture, aspiration and drainage on diagnosis and treatment of local complications of severe acute pancreatitis (SAP). Methods Forty-three cases of SAP combined with pancreatic necrosis, peripancreatic hydrops, pseudocyst and abscess were analyzed, all of them underwent CT guided percutaneous puncture, aspiration and drainage. Results The punctures were performed on 43 SAP patients for sixty-four times, the success rate was 100%, and in 24 cases of them puncture were performed for diagnosis, the positive rate of fluid absorption by puncture was 100%. Forty-one of 43 cases (95%) received puncture and tube drainage, open operation was performed in one patient, one patient was automatically discharged. The remission rate of abdominal distension was 93% (40/43) and 16 of 43 cases (37%) were turned to open operation. The effective rate of drainage was 61% (25/41). Conclusion The puncture, aspiration and drainage guided by CT is an effective method in diagnosis and treatment of local complications in part of SAP cases.
