[The mechanism and clinical applied skills of "curettage and aspiration" technique].

Objective: To investigate the mechanism of "curettage and aspiration" and to conclude its applied technique.

Methods: 2213 complicated abdominal cases, which operation were performed with the PMOD and its "curettage and aspiration" technique from November 1997 to May 2006, were analyzed retrospectively. Meanwhile, the successful rate of operations, the duration of operation, the blood loss of operation and the postoperative complications were statistically analyzed.

Results: Each operation was successfully accomplished without damage of the big blood vessels and the biliary tracts. The mean blood loss of pancreatoduodenectomy and radical gastrectomy for cancer, were respectively 105 ml and 75 ml, the mean duration was respectively 3.6 hours and 2.3 hours. As to the acute cholecystitis, the resectable rafe of gallbladder was 100%. Furthermore, no case needs blood transfusion, no massive hemorrhage and concerned damage happened when performing the operation for retroperitoneal tumor.

Conclusion: With reasonable operational principles and applied techniques, PMOD (Peng's multifunctional operativedissector) and "curettage and aspiration" technique have demonstrated its specific superiorities in the complicated abdominal operations.
