Skin adhesive (Octyl cyanoacrylate - LIQUID BAND©) is increasingly used instead of suture for sutures on the superficial plane of the skin.

It is frequently used in children, in traumatology and in plastic surgery. Several randomized trials have shown satisfactory results of the glue compared to suture in terms of infections and scar dehiscence, and aesthetics after abdominoplasty and mammoplasty.

In the field of port-a-cath® placement in oncology:

• The use of skin adhesive can save substantial nursing time, which makes it possible to consider the transition of this technique into routine patient management. Potential benefits include nurses managing large numbers of patients in day hospitals, and patients no longer needing a nurse for suture removal.
• Cancer and chemotherapy toxicity can alter patients' body image and view of themselves. The presence of a scar can be traumatic for some patients. The second goal of this study is to test whether the use of glue can improve the appearance of the scar following port-a-cath® placement, an area in which there are divergent results.
