NCT06243796

Brief Summary

The goal of this clinical trial is to evaluate the effectiveness of mastectomy flap fixation in breast cancer patients. The main questions it aims to answer are: \- To compare seroma formation after mastectomy flap fixation with conventional surgery in breast cancer patients Participants will be randomly divided into 2 groups,

  1. 1.Mastectomy flap fixation
  2. 2.Conventional surgery with non flap fixation. Researchers will record the amount and color of drainage fluid, patient and tumor characteristics, and operative related factor after surgery.

Outcome Measures

Primary Outcomes (1)

  • Seroma Formation

    Every day for 7 days post operative period, fluid from drains was recorded (ml) daily. After discharge during follow up period, seroma formation was observed if seroma was observed, aspiration was performed and recorded.

    Every day for 7 days post operative period and after discharge 7, 15, 21, 42, 63, 84 days during follow up period.

Secondary Outcomes (1)

  • Complication After Surgery 1. Wound Infection 2. Joint Stiffness 3. Visit Before the Appointment Date

    Data were assessed 7 days after operation, after discharge 7 days, 15 days, 21 days, 42 days, 63 days, 84 days. Data from any time point were combined by counted and sum number of specific outcome of interest.

Study Arms (2)

Flap fixation

EXPERIMENTAL

After completing the modified radical mastectomy procedure, the researcher will use absorbable suture (vicryl), multiple alternating stitches 2.5 cm apart between the subcutaneous tissues of the skin flaps and the underlying muscles at various parts of the flap and also, at the wound edge.

Procedure: Flap fixation technique

Non flap fixation

NO INTERVENTION

After mastectomy, the researcher will close the wound in the conventional method.

Interventions

After complete the modified radical mastectomy procedure, the researcher will use absorbable sutures (vicryl), multiple alternating stitched 2.5 cm apart between the subcutaneous of the flap and underlying muscle
