Abdomen CT and Open Appendicectomy：New Diagnostic and Surgical Procedures

Not Applicable

Completed

• Conditions: Complication; Scar; Wound Infection
• Interventions: Other: traditional incision; Radiation: The application of abdomen CT

• Registration Number: NCT02574364
• Lead Sponsor: Ningbo Municipal No.4 Hospital

Brief Summary

The traditional open appendectomy in the clinical effect is not prefect, and for a long time there is no measurable improvement. The application of abdomen CT before surgery provides a new approach to the incision and new perception.

In a randomized controlled trial of modified incision versus traditional incision. Length of hospital day was the primary terminus, while operating time, postoperative complication, scar and time to resume normal activity and work as secondary terminus.

Detailed Description

Traditional open appendicectomy have many drawbacks, such as false-positive, cut infection, scar, extended cut, slower rehabilitation and return to work. In the past few years, in order to improve diagnostic accuracy, the abdomen CT is been general applied before appendicectomy, in addition to, a modified incision (MI) was designed based on it. Using a MI compare traditional incision (TI) to the patient including cut extended, operating time, cut infection, false-positive rate, rehabilitation and return to work. It seems that MI would prove superior to TI in terms of hospital day (primary terminus), with operating time, postoperative complication, scar and time to resume normal activity and work as secondary terminus.
