Surgery for rectus diastasis is not simply about “bringing the muscles together”.
The aim is to reconstruct the abdominal wall, restore the continuity of the midline and recover proper force transmission between the rectus muscles, the lateral muscles, the diaphragm and the pelvic floor.
The operation can also treat at the same time:
Today many reconstructions can be performed with a laparoscopic or robotic approach, avoiding a large central incision and choosing the anatomical plane and technique best suited to each patient.
When should surgery be considered?
Surgery may be considered when the condition causes a clinically significant problem, for example in the presence of:
Persistent symptoms
Functional problems that do not resolve over time.
Functional instability
Loss of containment and control of the abdominal wall.
Daily limitations
Impact on daily, sporting or work activities.
Associated hernia
Presence of an umbilical or epigastric hernia along the midline.
Anatomical alteration
Significant change in the midline and its function.
Failure of conservative treatment
Persistent symptoms despite an adequate rehabilitation programme.
The decision must be made jointly with the patient.
The surgical objective: reconstructing the midline
The aim is to reconstruct the midline of the abdominal wall, restoring proper fascial continuity and, where present, treating associated hernias at the same time.
The surgical strategy depends on:
- configuration of the diastasis;
- presence of hernias;
- patient characteristics;
- any previous surgery.
From an “open belly” to a stable core again
The linea alba is the central point of force transmission between the two sides of the wall.
When it is too wide, the action of the abdominal muscles can become less effective and the patient may experience:
- instability
- difficulty controlling the trunk
- a feeling of giving way
Surgical reconstruction aims to bring the rectus muscles back to a physiological position and restore tension in the fascial system.
This can help to:
Surgery does not replace muscle function:
it rebuilds the anatomy on which the muscular system can work properly again.
Restoring the waistline
In some reconstructions, when the posterior compartment is mobilised, the lateral musculofascial complexes are brought medially together with the reconstruction of the central line.
This can contribute not only to wall stability but also to better waist definition.
The aim is not to artificially tighten the abdomen, but to bring the different compartments of the wall back to more physiological anatomical relationships.
Correcting lateral diastasis, when present
When midline and lateral diastasis coexist, the reconstruction must take both into account.
Some techniques that mobilise the posterior compartment already medialise the lateral muscles; in other cases a direct correction of the lateral component may be needed.

In recent years several laparoscopic, endoscopic, extraperitoneal and robotic procedures have been developed to reconstruct the midline through small incisions.
Laparoscopic surgery
Laparoscopy allows surgery through small incisions and a view of a wide area of the abdominal wall.
Depending on the technique, it is possible to:
- reconstruct the midline
- treat multiple hernias at the same time
- work in retromuscular or preperitoneal planes
- place a mesh outside the peritoneal cavity
- avoid a large midline incision
Robotic surgery
Robotic surgery uses the same anatomical principles as minimally invasive surgery, but offers greater instrument articulation and can facilitate complex dissections and sutures in deep anatomical spaces.
Minimally invasive techniques used
The technique is chosen after precisely defining the type of diastasis and any associated defects.
Minimally invasive procedures that can be used in selected patients include:
miSAR® and p-miSAR®
A technique developed for minimally invasive midline reconstruction with retromuscular mesh placement.
It allows diastasis and any midline defects to be treated at the same time.
Restores the waistline.
eTEP
An extraperitoneal approach that creates and uses the retromuscular plane without entering the abdominal cavity.
It can be used for midline reconstruction and treatment of associated hernias.
peTEP
An extraperitoneal approach that plicates the midline and places a preperitoneal mesh.
It can be used for hernia and diastasis defects of the midline and lateral defects.
v-TAPP
An intraperitoneal approach that repairs the defect and places the mesh, separating it from the viscera with the peritoneum.
It can be used for midline hernia and diastasis defects and lateral defects.
All procedures can be performed LAPAROSCOPICALLY or ROBOTICALLY
Is a mesh always necessary?
Often, yes.
What changes is:
Type of mesh
- 1Absorbable
- 2Partially absorbable
- 3Non-absorbable
Mesh position
- 1Retromuscular
- 2Preperitoneal
- 3Intraperitoneal
How common is recurrence?
Minimally invasive techniques have very low recurrence rates, around 1%.
The abdominal wall should be reconstructed properly the first time.
- 1
A recurrence does not simply mean “repeating the same operation”: each new operation meets scars, altered anatomical planes and previously treated tissues, making surgery progressively more complex.
- 2
This is why, when choosing an operation, the documented (that is, scientifically published) recurrence rate over time matters a great deal.
- 3
And when someone claims 0% recurrence, a fair question is: how long have they really followed up their patients?
In surgery, credible results are not perfect ones, but those that are transparent, measured and verified at follow-up.
Aesthetic result
All minimally invasive operations can be combined with a procedure performed together with a plastic surgeon.
The aim is to integrate two components:
reconstruction of the wall
treatment of the superficial tissues
Recovery after surgery
One of the advantages of minimally invasive approaches is the ability to combine an extensive wall reconstruction with a quick recovery.
Feeling better quickly does not mean that the fascia has already fully healed: the biological maturation of the reconstruction takes time.

The ultimate goal of surgery is not simply a narrower midline.
A reconstructed wall must be used again.
This is why the postoperative pathway may include progressive rehabilitation focused on:
- 1breathing and the diaphragm
- 2transversus activation
- 3control of intra-abdominal pressure
- 4pelvic floor
- 5trunk stabilisation
- 6return to sport
Reconstructing the wall creates the anatomical conditions; rehabilitation turns that reconstruction into function.
FAQ
Does every diastasis need surgery?
No. The indication depends on symptoms, the functional stability of the wall, associated hernias, anatomy and the outcome of any conservative treatment.
Can the operation be performed laparoscopically?
Yes, many reconstructions can be performed with a laparoscopic or endoscopic approach. The technique depends on the individual patient’s anatomy.
Is robotic surgery better than laparoscopy?
Not necessarily. Both allow minimally invasive reconstructions; the choice depends on the type of operation and the anatomical features.
Can diastasis recur?
Yes. No technique completely eliminates the risk of recurrence. Using techniques with low recurrence rates that are documented and scientifically published can help reduce the risk.
Do you have diastasis and want to know whether surgery is really necessary?
The first decision is not which technique to use, but understanding exactly which component of the wall needs to be reconstructed.
The assessment considers the midline, associated hernias, lateral compartments and functional symptoms to define a personalised treatment.
