NCT06930378

Brief Summary

The goal of this clinical trial is to learn if nerve sutures in free flap breast reconstruction can optimize sensibility in the reconstructed breast in patients opting for DIEP flap breast reconstruction due to breast cancer or genetic conditions. Affected women 18 to 80 years old can be included. The main question is: If a nerve suture was carried out, can pressure be felt better on the reconstructed breast after 12 months? If a nerve suture was carried out, will better sensibility and quality of life be felt and perceived (questionnaire) at 12 and 24 months after the initial operation ? Researchers will compare two different nerve suture techniques and no nerve suture to one another to see if and which nerve suture optimizes sensibility. Participants will have regular visits and follow-up controls, during which

  • their sensibility will be tested multimodally,
  • they will fill out questionnaires
  • skin biopsies will be taken.

Outcome Measures

Primary Outcomes (1)

  • Semmes-Weinstein-Monofilament-Test

    The results of one modality of the sensory testing, the Semmes-Weinstein-Monofilament-Test for pressure perception. The breast will be divided into 9 zones, which will all be measured with the Semmes Weinstein monofilament 20-piece full kit (unit: grams of force) at the given time (see time frame).

    At 12-months-follow-up

Secondary Outcomes (16)

  • Change in breast sensation

Study Arms (3)

no nerve suture

NO INTERVENTION

No nerve suture will be carried out.

direct nerve suture

EXPERIMENTAL

Epineural coaptation of one nerve of the flap to one nerve of the breast region

Procedure: Nerve Suture

interposition of an autograft

EXPERIMENTAL

Epineural coaptation intercostal nerve flap to autograft (from another intercostal nerve of the flap) to intercostal nerve of the breast = interposition of an autograft

Procedure: Nerve Suture

Interventions

Nerve SuturePROCEDURE

Sensory nerve coaptations will be performed 1. either by suturing the donor to the recipient nerve immediately (1 coaptation) 2. or by interposing an autograft originating from the zone of the flap to be discarded (2 coaptations). The anterior cutaneous branch (ACB) of the 3rd or 4th intercostal nerve (ICN) will be connected to the sensory branch of the 10th, 11th or 12th ICN of the flap.
