Endoluminal Gastroplication
An endoscopic approach to GERD
using the Bard® EndoCinch™
Suturing System
Background
First system to permit
suturing in GI track
with flexible
endoscope
Device attaches onto
standard upper GI
endoscope
Procedure
Sutures are placed at lower esophageal
sphincter
2 locations
Tied together to create a pleat (plication)
Has been shown to significantly improve
symptoms & regurgitation and reduce or
eliminate medications
Where to Stitch??
Squamocolumnar Junction
Z line
Stitching Below the Z-line
Z line
Scope advanced to LES
Overtube placed
Endoscope advanced
Identify tissue to be
sutured
Vacuum applied & tissue captured
Vacuum applied
Tissue captured
Stitch placed
Handle actuated
Stitch placed through
tissue bite
Scope withdrawn and
suture tag reloaded
Scope reinserted
Second stitch placed
adjacent to first
Knot Secured
Switch to endoscope
with suture anchoring
device
Load suture
Advance to site
Gastroplication formed
Actuate handle to cinch
and cut suture
Gastroplication formed

Summary
Device is safe & effective
73% improvement in HBSS
75% reduction in multiple meds or daily PPIs
90% patients have no or mild regurgitation
87% patients experienced an improvement or
maintenance of esophagitis
No significant effect on pH and manometry
Significant decrease in number of reflux episodes

Raijman, et. al.
Multi-Center Study
Presented by Isaac Raijman, MD DDW
2001
Study Design
Prospective Multicenter study
88 patients with symptomatic GERD
3 stitch configurations
Linear, circumferential, helical
Average follow-up: 9 months
Summary
Complete resolution of Heartburn: 85%
Complete resolution of Regurgitation: 90%
Discontinuation of medication: 74%
Comparative Summary
2 plications: 91% with favorable results
3 plications: 88% with favorable results
Large hiatal hernia (3-4 cm) had similar
response to those with hernias <3cms
Summary
The results of this study compare
favorably to those from the previously
reported multi-center trial
The practice of ELGP should continue
including patients with apparent less
favorable clinical parameters
European Clinical Experience
(Park et. al., Sweden)
Retrospective multicenter study
142 patients with symptomatic GERD
2 stitch configuration
12 week post procedure follow-up
Summary
Median LES length  from 1.5 to 2.5cm
Median pH time <4  from 8.4 to 3.9
Follow up suggest that good
improvements maintain at least 2-4 years
and that the stitches will stay intact
European Clinical Experience
(Mahmood et. al., Ireland)
Single center study
18 patients with symptomatic GERD
2 stitch configuration
3 month follow-up
Summary
Heartburn frequency  from 79% to
27%
Heartburn severity  from 72% to 24%
Regurgitation  from 64% to 18%
PPIs/H2Rs use  80%
Mean pH DeMeester  from 42 to 25
