German: LESS-Chirurgie

1 Definition

Laparo-Endoscopic Single-Site surgery, abbreviated LESS surgery, reduces the invasiveness of laparoscopic procedures.

2 Advantages

2.1 for patients

Just one small incision in the abdominal wall is all that is needed to secure access for multiple instruments simultaneously. If the incision is made in the umbilicus, the surgical scar is hidden and nearly invisible. The key to this evolution in minimally invasive surgery lies in the newly designed TriPort that allows simultaneous access for multiple instruments to the abdomen. This way, conventional introduction of multiple trocars can now be reduced.

Reducing the number of incisions to only a single incision in the umbilicus can result in less morbidity and a better cosmesis.

Whilst the benefit of better cosmesis is clear, the benefits resulting from LESS surgery’s reduced morbidity remain to be proven in clinical studies.

Surgeons employing this innovative technique contend that patients can potentially benefit from:

  • Less postoperative pain
  • Less blood loss
  • Faster recovery time
  • Fewer complications
  • Fewer hospital days
  • Better cosmetic results

2.2 for hospitals

There may also be a positive effect for hospitals in terms of cost reduction due to:

  • Decreased risk of wound infections
  • Reduced use analgesia
  • Shorter hospital stays

3 Range of applications

In LESS surgery, the only difference from conventional laparoscopy is the number of entry sites into the abdomen. The surgical procedure itself is similar to that of conventional laparoscopic procedures. Therefore, the LESS approach could theoretically be adapted to all standardised laparoscopic procedures in the fields of

  • General surgery
  • Urology
  • Gynaecology

Hence LESS surgery has a wide range of applications. Recently, common procedures like cholecystectomy, nephrectomy and hysterectomy have been performed through a single port. A significant number of LESS procedures have been performed to date.

The establishment of LESS surgery is still in its initial stages (2017).
