Endoscopy management of Sleeve Gastrectomy Stenosis. What we learned from 202 consecutive patients



Gastric sleeve stenosis (GSS) is described in 1-4% of patients.


To evaluate the role of endoscopy in the management of post Laparoscopic Sleeve Gastrectomy
(LSG) stenosis, using a standardized approach according to the characteristic of stenosis.


Retrospective, observational, single center study on patients referred from several
bariatric surgery departments to an endoscopic referral center.


We enrolled 202 patients. All patients underwent endoscopy in a fluoroscopy setting,
a systematic classification of type, site, and length of the GSS was performed. According
to the characteristics of the stenosis, patients underwent pneumatic dilatation, Self-Expandable-Metal-Stent
(SEMS) or Lumen-Apposed-Metal-Stent (LAMS) placement. Failure of endoscopic treatment
was considered an indication for redo-surgery, while patients with partial or complete
response were followed up for 2 years. In case of recurrence a different endoscopic
approach was performed.


We found inflammatory strictures in 4.5%, pure narrowing in 11%, and functional stenosis
in 84.5% of patients. Stenosis was in the upper tract of the stomach in 53 patients,
while medium and distal stenosis was detected in 138 and 11 patients, short stenosis
in 194 out of 202 patients. 126 patients underwent to pneumatic dilatation, 8 to SEMS
placement, 64 to LAMS position and 36 to combined therapy. Overall rate of endoscopy
success was 69%.


GSS should be considered as a chronic disease and endoscopic approach seems to be
the most successful treatment with a prolonged positive outcome of 69%. Characteristics
of the stenosis should guide the most suitable endoscopic approach.
