ABSTRACT
Background: The considerable increase in Obesity and especially the increase in super obese patients (Body Mass In-
dex—BMI 50 Kg/m2) who require surgery lead doctors to search for surgery techniques which give good results in
terms of a consistent and stable weight loss associated with low morbidity and good quality of life. The Long Magen-
strasse (LM) intervention, born from combining two properly modified surgical procedures (Selective Vagotomy with
pyloric divulsion and Mangestrasse & Mill by Johnston) seems to have these characteristics according to our experience
after operating on 660 patients. Methods: From October 2003 to October 2008 we treated 186 patients with LM. One
hundred and sixty-two patients were regularly present to the annual follow-up, but 24 patients didn’t turn up, therefore,
they were contacted by phone. On average, surgery lasted approximately 80 minutes (range: 50 - 90 minutes). Thirty
patients were super obese with an average BMI of 57.4 Kg/m2; 156 patients were grade II and III obese with an average
BMI of 40.7 Kg/m2. Results: The average BMI of the 30 super obese patients decreased from 57.4 Kg/m2 to 35.9
Kg/m2 one year after surgery, to 35.6, 5 years after surgery and it has remained stable until now. In the 156 patients
suffering from II and III grade obesity, the average BMI decreased from 40.7 Kg/m2 to 27.8 Kg/m2 one year after sur-
gery and it has remained stable until now. Out of all super obese diabetic patients, only one has partially maintained
his/her therapy. Patients have reported a decreased appetite since the very first days of post-operative period with an
early sense of satiety which is unchanged until today. Conclusions: A consistent and stable weight loss over 5 years
after surgery even in Super Obese patients, a decrease in appetite with an early sense of satiety, a re-equilibrium of the
metabolic syndrome in particular of Diabetes Mellitus, allow to classify LM among those surgical treatments with a
mixed mechanism of action: both restrictive and functional, in particular, entero-hormonal and gastric neurosecretory.

1. Introduction
When performing Sleeve Gastrectomy (SG), each sur-
geon chooses the measures that he/she considers the most
suitable ones: from 3 to 8 cm distant from the pylorus with
conservation or non-conservation of the antrum, a calibra-
tion bougie ranging between 32 and 50 Fr. resulting in
great variability in results especially over time [1, 2].
Whereas, in the LM the surgical technique is very pre-
cise and its results are absolutely reproducible [3,4].
The suture-section stretches from the angle of His up
to 2 - 3 cm from the pylorus on a calibration bougie of 36
Fr., in this way the stomach appears uniformly tubular at
the level of the small curvature (food tract). The rest of
the stomach (corpus and fundus) is excluded from food
transit while still producing gastric juices which flow
into the 3 cm dimension prepyloric “Mill” (secretory
pathway).
Without distal pouch, which could experience dilation
over time, gastric conservation allows surgeons to stretch
the suture-section up to 2 - 3 cm from the pylorus. In
order to ease the transit of food bolus, a pyloric divulsion
is carried out resulting in good gastric drainage which
reduces the possibility of gastro-oesophageal reflux.
Another consequence of the long suture-section is se-
lective vagotomy that determines a consistent reduction
in gastric secretion (20% - 30%) [5] which is, anyway,

proportional to the amount of food eaten (surgery restric-
tive aspect).
Differently from SG where corpus and fundus are re-
moved, in the LM technique, despite being present, they
are not transited by food, therefore, there are no stimuli
to the production of ghrelin as it happens in gastric
banding or in the traditional BPD (Biliopancreatic Diver-
sion) [6,7].
Another positive datum of LM is the physiological
transit of food through the duodenum-jejunum without
the “dumping syndrome” which is instead frequent in
those techniques implying a direct gastro jejunal transit.
During a gastroscopy, where each part of the stomach
can be studied, a biliary reflux inside the “Mill” has
never been noticed, probably thanks to a simple pyloric
divulsion instead of a real surgical pyloroplasty.
2. Materials and Methods
In October 2003 we started using LM for treating great
obese patients; until December 2012, 660 patients were
operated on with this procedure.
All patients underwent a pre-operative internistic-die-
tological screening with possible respiratory rehabilita-
tion more or less protracted over time until reaching an
Apnea/Hypopnea Index (AHI) inferior to 5.
From October 2003 to October 2008 we treated with
LM 186 patients, 147 women (79%) and 39 men (21%)
with an average age of 39 (range: 16 - 62) and an average
BMI of 45 Kg/m2.
Thirty patients were super obese with an average BMI
of 57.4 Kg/m2; 156 patients were II and III grade obese
with an average BMI of 40.7 Kg/m2 (Table 1).
Out of these 30 super obese patients, 21 were women
and 9 were men with an average age of 39 (range 16 -
54); 16% suffered from Pickwick syndrome, 36% from
dyslipidemia 16% was affected by hyperuricemia and
34% by arterial hypertension.
The average time of intervention with “open” surgery
with median or left subcostal laparotomy lasted 80 min-
utes; in the other cases surgery was performed with
videolaparoscopy or hand-assisted videolaparoscopy.
The pylorus divulsion was digitoclastic in “open” sur-
gery or hand-assisted videolaparoscopic, pneumatic-en-
doscopic in case of videolaparoscopic procedure.
All patients underwent heparin prophylaxis and an

The follow up of the patients who underwent surgery
is as follows: 3 months, 6 months, 1 year after surgery
and then each year until now.
One hundred and sixty-two patients were regularly
present to the annual follow up, 24 patients didn’t turn up,
therefore, they were contacted by phone.
3. Results
In the 30 super obese patients operated on over 5 years
ago the average BMI shifted from a preoperative value of
57.4 Kg/m2 (range 50 - 74) to 38.3 Kg/m2 one year after
surgery, to 35.65 years after surgery and to a current
value of to 35.9 Kg/m2 (range 23 - 54) with an average
%EWL (Percentage of Excess Weight Loss) of 60.16
(range 34 - 97) (Figures 1 and 2).
In the 156 II and III grade obese patients the average
BMI decreased from a preoperative level of 40.7 Kg/m2
(range 35.3 - 48.4) to 26.6 Kg/m2 after one year from
surgery, to 26.7 Kg/m2 5 years after surgery and to 27.8
Kg/m2 (range 19.6 - 35.8) with an average % EWL of
69.4 (Figures 3 and 4, Table 2).

In the 186 patients ope
e most frequent complication, which generally ap-
peared 6 - 12 months after surgery, is, generally, the
postprandial, and never the nocturnal, gastro-oesophageal
reflux (9% of patients who underwent surgery), probably
due to a recovered pyloric tone; the treatment is endo-
scopic and consists in a pneumatic dilation of the pylo-
rus.

action given by the combination of a gastric restriction,
entero-hormonal effects, a change in motility, gastric
secretion and, obviously, in eating habits.
Differently from S.G., where measures of residua
ach are not standardized and each surgeon can choose a
distance from the pylorus ranging from 3 to 8 cm and a
calibration bougie ranging from 32 to 50 Fr. with great
variability in the results especially over time, in the LM,
the technique requires specific measures with reproduci-
ble results.

2 - 3 cm from the pylorus with a calibration bougie of
36 Fr. resulting, this way, in a uniformly tubular stomach
at the small curvature (food tract). The rest of the stom-
ach (corpus and fundus) is excluded from food transit
while still producing gastric juices which flow into the 3
cm dimension prepyloric “Mill” (secretory pathway).
In order to stop the bolus from descending the duo
m and reaching back the excluded stomach, a pyloric
divulsion is fundamental because it resolves the pyloric
spasm secondary to the vagal nervous interruption;
therefore, the food bolus transits easily also thanks to the
lack of a prepyloric “pouch” which requires an effective
emptying pump.

It should be noted that it is possible to explor
doscopic route also the part of the stomach excluded
from food transit.
As reported by Drazen et al. [8], although ghrel
been dosed in the considered patients, it is reasonable to
assume that it has an important role in the modulation of
appetite. After surgery, in fact, the fundus of the stomach
is excluded by the food tract and, consequently, the cells
responsible for the secretion of ghrelin are not involved
in the stimulation by the food ingested; this aspect inevi-
tably results in a reduced endocrine secretion of ghrelin
which determines an inhibition of the hormonal cascade
that promotes the sense of hunger. Afterwards, food bo-
lus, thanks to the pyloric divulsion, reaches more rapidly
the duodenum and the jejunum, site of GIP (Gastric In-
hibitory Polypeptide) and PYY (Peptide YY) synthesis.
Reinehr et al. [9] and Valderas et al. [10] showed that a
more rapid intestinal transit of the partially digested food
bolus through these intestinal tracts triggers an increase
in the secretion of GIP and PYY resulting in an early
sense of satiety due to hypothalamic stimulation. More-
over, GIP and PYY together with the quick transit of
partially digested food, stimulate iliac L cells to secrete
GLP-1 (Glucagon-Like Peptide-1), which exerts its sec-
retory effect improving insulin sensitivity and promoting
the sense of satiety.
Furthermore, the an
at, concurrently to weight loss, patients improve their
dyslipidemic pathology by remarkably reducing cardio
vascular risks.
5. Conclusio
Important character
1) Gastric conservation with functio
ced, helps maintain a good metabolic-nutritional bal-
ance over time.
2) Tubular prep
e without any possibility of dilation as it can, some-
times, happen in the SG: we believe this to be an essen-
tial characteristic to avoid weight gain over time.
Finally, we should underline the high percentag
od quality of life in terms of food “compliance”: eating
solid and varied foods.
