33.1 Summary
Our experience with over 1400 MILOS surgeries
in abdominal wall and incisional hernias showed
the following advantages of using this technique:
1. Minimally invasive extraperitoneal implantation of (large) standard synthetic meshes
without traumatic mesh xation.
2. Closure of hernia gaps and anatomical
reconstruction of the abdominal wall.
Protection of viable abdominal wall structures including nerves.
3. Aer MILOS operations, there were signicantly less postoperative surgical complications, general complications and less chronic

34.1 Introduction
e optimal operative treatment of primary and
secondary hernias of the abdominal wall is still
debatable. Traditional open techniques are burdened with a high rate of infection [1], whereas
the laparoscopic intraperitoneal onlay mesh
(IPOM) repair carries an increased risk for intraoperative lesions to the bowel, adhesions, and
bowel obstructions [2–4]. Despite great progress
in mesh technology and development of expensive meshes promising less formation of adhesions between the mesh and the intestine, the
potential risk of an intraperitoneal foreign body
has not yet been solved [5]. Furthermore, the
IPOM technique typically requires expensive xation devices and, more important, xation with
tacks or sutures causes severe acute and chronic
pain. In order to avoid these disadvantages of current open and laparoscopic techniques, the
MILOS (mini/less open sublay) concept was
developed by W.Reinpold (7 Chap. 33). e aim
of this novel technique is to keep the mesh out of
the abdominal cavity. Following the MILOS concept, the surgeon is able to place a large mesh into
the retromuscular plane through a small skin
incision (2–6 cm = mini open; 6–12 cm = less
open). e MILOS operation is an open procedure, using endoscopic dissection instruments
and a novel specically designed light tube which
facilitates exposure, visualization, and retraction
(Endotorch, Wolf TM). Despite this new innovative device, the technique which is extensively
described in 7 Chap. 33 may be technically challenging especially not at least because the assisting surgeon’s view is limited. erefore, in order
to increase utilization of the “MILOS concept,” we
developed the endoscopic mini/less open sublay
(EMILOS) operation which is essentially a
reversed total extraperitoneal(TEP) procedure
[6]. is variation of the original MILOS operation is a true hybrid technique which consists of
two parts, the rst steps (step 1–4) are identical to
the MILOS operation, then immediately aer
opening of the rectus sheath, the operation continues with endoscopic dissection “reversed TEP”
of the total retromuscular space.
34.2 Operative Technique
Aer initiation of general anesthesia, the patient
is placed at on the operating table with the legs
in the French position like performing a laparoscopic cholecystectomy (. Fig.34.1a, b).
During the endoscopic part of the operation,
the surgeon will stand between the legs of the
patient. No special instruments are needed
except a self-constructed low-cost indigenous
balloon [7, 8] used to develop the preperitoneal
space just proximal to the pubic bone as in
TEP.Steps 1 to 4 are identical to the MILOS operation (see 7 Chap. 33).
Step 1 e endoscopic part (E) of the MILOS
operation begins with a small incision of the posterior sheath of the rectus muscle on one side. e
rims of the opened fascia are marked with holding
sutures.
Step 2 Introducing of a curved sponge forceps
(Kornzange) into the rectus sheath and pushing
down directly on the back wall of the sheath in caudal direction toward the symphysis.

. Fig.34.2 Indigenous balloon [7, 8]
. Fig.34.3 The balloon is pushed down into the
suprapubic extraperitoneal space
Step 3 Removal of the forceps and replacement
by an indigenous balloon-like in TEP [7, 8]. e
balloon is prepared by capping the tip of a 5mm
suction irrigation cannula with the middle nger of
a number 8 latex glove (. Fig.34.2). e nger of
the glove is tied tightly onto the tip of the cannula
with some bandage material or some sutures.
Before introducing into the retromuscular/preperitoneal space, the patency or any leak from the side
of the glove nger should be checked by inating
with normal saline solution and aspiration.
Step 4 e balloon is pushed down into the extra-
peritoneal space (. Fig.34.3) just in front of the
symphysis and inated with about 300ml of saline
solution to create a space for safe introduction of a
12mm camera port later on. Aer aspiration of the
uid, the cannula is withdrawn and replaced by a
camera port with a 10mm optic (. Fig.34.4).
. Fig.34.4 Replacement of the balloon by a camera
port with a 10mm optic
. Fig.34.5 Suprapubic retromuscular plain
Step 5 Insuation of carbon dioxide into the
already preformed preperitoneal space. In order to
avoid loss of gas during this step, the previously
mentioned holding sutures at the entrance to the
rectus sheath are xed to the port.
Step 6 Aer a complete creation of the space
under direct visualization (. Fig.34.5), the 12mm
port may be safely inserted and will accommodate
the camera and will be used to introduce the mesh
aer a complete dissection of the retromuscular
space (. Fig.34.6).
Step 7 Removal of the 10mm port which had
been introduced through the wound at the umbilicus. Now, the opposite side of the posterior sheath
of the rectus muscle is also incised. ese incisions
of the posterior wall of the rectus sheath on both
sides are continued caudally and cranially as far as

368

it is convenient in relation to the small skin incision. Note: e linea alba must be preserved; therefore, rst, the preperitoneal fat and the peritoneum
attached to the midline should be pushed down
before safe longitudinal incision of the posterior
rectus sheath is possible.
. Fig.34.6 The suprapubic camera trocar is placed
(arrow)
Step 8 Gentle blunt detachment of the posterior
sheath of the rectus muscle using the curved
sponge forceps as far as it is possible, which is very
easy to do.
Step 9 Provisionally tight closure of the skin inci-
sion. Introducing the 10mm optic (30°) via the
12mm port into the preperitoneal space proximal
to the symphysis (. Fig. 34.7). Insuation of the
carbon dioxide up to a pressure of 14mmHg.
Step 10 Endoscopic visualization of the retro-
muscular space with the surgeon standing between
the legs and the video tower behind the head of the
patient. Starting the endoscopic dissection
(reversed TEP) aer introducing a 5mm working
trocars on each side laterally to the midline in the
medio-clavicular line and about 3–5cm above of
the umbilicus under direct view (. Fig.34.8).
Continuation of the incision of the posterior
rectus sheath cranially up to the costal margin
and the xiphoid (. Fig.34.9). e space behind
the costal margin as well as behind the sternum
(fatty triangle) is easily dissected and opened for
later mesh placement. It is important to preserve
the linea alba (. Fig. 34.9). Complete blunt
detachment of the fascia from the rectus muscle
while carefully preserving the vessels and the
nerves perforating the fascia laterally.
. Fig.34.7 The skin incision at the umbilicus is
provisionally closed
. Fig.34.8 Placement of
the working trocars, later
followed by a second optic

34.3 Preliminary Results
Between June 2015 and September 2016, a
total of 33 patients were operated by EMILOS
technique. The indication for operation was in
19 patients with an umbilical/epigastric her-
nia in combination with a rectus diastasis and
in 14 patients with an incisional hernia. In 31
patients the size of the implanted mesh was
20 × 30cm, in 2 patients it was 16× 30 cm.
The results are shown in
. Table 34.1. No
intraoperative complications were observed.
2–4 days). Postoperatively two complications
were observed. One patient developed a small
superficial wound necrosis, which was excised;
the further course was uncomplicated. The sec-
ond patient suffered from a severely infected
seroma; therefore the mesh was removed
3weeks after the operation.
e postoperative pain score between the h
and seventh postoperative day was in rest below
VAS 3 and under physical stress 3.9 (range VAS
0–6).
e late cosmetic results are excellent

34.4 Discussion
e ideal indications for this new operation technique are primary or secondary ventral hernias in
patients presenting an additional signicant rectus diastasis (. Fig.34.1a). In these patients, mid-
line prosthetic augmentation of the whole
abdominal wall is recommended as the rate of
recurrence is high in this group [9]. Early results
of the EMILOS technique in the therapy of primary and secondary ventral hernias are promising [6]. e impetus to develop novel minimally
invasive operative techniques which enables the
surgeon to get the mesh out of the abdominal cavity has been a new and exciting trend in hernia
surgery. e combination of the benets of the
open extraperitoneal and retromuscular repair
with the smaller incision and lower wound morbidity of laparo-endoscopic surgery provides the
primary benets of each of these repairs while
avoiding their limitations.
In 2004, Conze etal. [10] pointed out that the
incision of the posterior rectus sheath and the
opening of the “fatty triangle” is an important step
of open retromuscular mesh repair, which enables
the surgeon to position the mesh behind the
xiphoid and the costal margin for prevention of
recurrences. erefore the posterior lamina of the
rectus sheath in its upper part must be le open in
this technique. However, Reinpold etal. (7 Chap.
33
) did not close the posterior rectus sheath at all
in the vast majority of their MILOS cases.
According to his experience, the complete closure
of the posterior rectus sheath seems to be not necessary for the success of the operation. But, both
authors claimed the reconstruction of the linea
alba in open sublay repair respectively and the
preservation of the anterior sheath in MILOS
technique as indispensable steps of the repair. In
most of our EMILOS patients, we also didn’t
suture the posterior sheath accordingly, but in
some of these cases, we observed an unpleasant
bulging in the midline of the upper abdominal
wall. erefore, to prevent any bulging, in the last
seven cases, we sutured the middle and lower part
of the rectus sheath. Indeed, in the follow-up
regarding the shape of the abdominal wall, these
patients showed a better cosmetic result compared with the early cases.
e recent literature reports several techniques for reconstruction of the midline in
patients with rectus diastasis by suture plication
and mesh augmentation without performing a
large skin incision [11, 12]. e disadvantage of
one of these two studies is that the mesh is placed
in an unfavorable subcutaneous position [11];
the second study recommends that the mesh
should be pushed through the hernia defect into
the preperitoneal plane [12]; therefore, only
meshes with a limited size may be implanted.
Moreover, these procedures are complicated by a
high frequency of seroma formation [12]. Other
authors propagate the transabdominal route in
order to bring the mesh into the preperitoneal
retromuscular position [13, 14]. e disadvantages of these transabdominal techniques are as
follows: (1) enhanced risk for bowel lesion [13,
14], (2) technical diculties [13, 14], (3) use of
several linear cutters [14] which increases the
costs dramatically, (4) use of countless tacks [14]
which increases the risk for pain, and (5) limited
size of mesh [13, 14] which increases the risk for
recurrences. According to our experiences utilizing the EMILOS repair, these disadvantages are
avoided (6). e best current indications for
EMILOS are patients presenting with a primary
or secondary hernia in the midline and concurrent rectus diastasis. Each step of the EMILOS
operation is well standardized and improved for
routine clinical use.
34.5 Conclusion
In conclusion, both new techniques, MILOS and
EMILOS, are patient friendly, produce remarkable less acute and chronic pain, minimize the
amount of abdominal trauma, avoid traumatic
mesh xation or expensive mesh, and get the
mesh out of the abdominal cavity. Both techniques are standardized, reliable, and reproducible. Mini-open and videoendoscopic steps are
complementary and indispensable parts of the
MILOS concept. Future studies are necessary to
clarify which technique will be the best for the
specic hernia and individual patient.
