Introduction
• GERD is a chronic disease of upper GI tract as a
cause of complex mechanisms defects, resulting in back flow of gastric contents to the
esophagus, that presents with GI and extra-GI manifestation.
• affecting up to 40% of people in the Western world.

Mechanisms for GERD
• By Orlando R,1- TLESR2- Hypotensive or incompetent LES3- Anatomic disruption of EGJ. Refluxate material: - Acid - Bile- Gas

Aim of treatment
– Control acute GERD symptoms
– Maintain the control
– Prevent long-term complications

Complications • Complications, during or the after the operation in 5-
15% of cases • Serious problems is around 2-8% of patients, with
around 2% requiring a new operation• Difficulties swallowing persist for longer than 3 months in
only 10%. After 1 year, it’s around 2% • Diffuse abdominal complaints• Thee is about a 10% risk of reflux disease reoccurring • Despite all the risks to be taken into consideration, the
fact remains that in around 90% of reflux cases a long-lasting cure of reflux disease can be achieved.

Clinical data 1
• Dallemagne B et al (Surg Endosc. 2005 Dec 5):100 consecutive patients who underwent LAS by a single surgeon in
1993 Evaluations of the outcome were made 5 and 10 years after surgery
At 5 years, 93% of the patients were free of significant reflux
symptoms. At 10 years, 89.5% of the patients still were free of significant reflux
(93.3% after Nissen, 81.8% after Toupet). The GIQLI scores at 10 years were significantly better than the
preoperative scores of the patients under medical therapy with proton pump inhibitors.
Four patients underwent revision surgery: one patient for persistent dysphagia and three patients for recurrent reflux symptoms

surgery is superior to PPI therapy

GERD& Barrett’s esophagus
• Surgical therapy:– Controls symptoms of GERD– Controls acid & bile reflux– May prevent or slow progression– May cause regression

GERD & Pregnancy
• Two thirds of pregnant pt develop HB
• ? Progesterone, ? High intra A pressure
• Al-Amri SM (Eur J Obstet Gynecol Reprod Biol. 2002 ),
Pregnancy is associated with decreased LES pressure, more frequent episodes of reflux and upright reflux.
![Page 33: Gastro-esophageal Reflux Surgical Management Fahad Y. Bamehriz, MBBS, SBIS](https://reader038.vdocuments.net/reader038/viewer/2022102907/56649d9c5503460f94a8444d/html5/thumbnails/33.jpg)
Clinical data
• Bamehriz (Surg End-2005), of 146 child-bearing age women, 25 pt became
pregnant after LNF 5of 25 patients (20 %) developed dyspepsia
during their pregnancy 1 patient (4%) developed acute intra-thoracic
herniation of the stomachHowever, for majority laparoscpic Nissen
fundoplication provides effective control of their reflux symptom during and after pregnacy
![Page 34: Gastro-esophageal Reflux Surgical Management Fahad Y. Bamehriz, MBBS, SBIS](https://reader038.vdocuments.net/reader038/viewer/2022102907/56649d9c5503460f94a8444d/html5/thumbnails/34.jpg)
GERD &TLESR
• TLESR cause 70-100% of reflux episodes in normal person. 63-74% in GERD pt.
• PPI has no effect on TLESR
• Bamehriz et al (Surg Endo-2004),
73 pt with GERD +TLESR
TLESR is significantly reduced to a mean number of 0.19 per pt from 2.4 per pt
Only 8/73 pt had TLESR post LNF
![Page 35: Gastro-esophageal Reflux Surgical Management Fahad Y. Bamehriz, MBBS, SBIS](https://reader038.vdocuments.net/reader038/viewer/2022102907/56649d9c5503460f94a8444d/html5/thumbnails/35.jpg)
LNF & NERD
• Kamolz,Pointner et al (Surg End-2005),
- 89/500 pt had NERD who underwent LNF
- Compared with EGD-positive GERD pt
- Follow-up was 5 years
- GIQLI was significantly better in NERD pt
![Page 36: Gastro-esophageal Reflux Surgical Management Fahad Y. Bamehriz, MBBS, SBIS](https://reader038.vdocuments.net/reader038/viewer/2022102907/56649d9c5503460f94a8444d/html5/thumbnails/36.jpg)
GERD & Cough
• Anvari et al (Surg Endo-2005),
- 209 pt had GERD+ cough, underwent LNF
- 60% has 5 years follow-up
- Cough improved in 71% of pt at 5 years
- LNF is successful in the long-term control of GERD-related Cough.

• 2- well-respond to PPI therapy

• Only 1 factor = < 50%
