Gastro-esophageal Reflux Surgical Management

Fahad Y. Bamehriz, MBBS, SBIS

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

Peri-operative information

Less pain medication

Hospital stay is 1 day

Back to regular activity within 5-7 days

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

Clinical data 2

• Beher and colleagues (NEJM-1975),

surgery is superior to antacid therapy

. Spechler and coworkers (NEJM-1992),

surgery is superior to H² blockers

. Lundell (J Am Coll Surg-1999),

surgery is superior to PPI therapy

Clinical data 2

• Mahon D (Br J Surg-2005),

surgery is superior to PPI therapy

. Olberg P (Scand J Gast-2005),

surgery is more effective than medical care

. Cookson R( Br J Surg-2005),

surgery maybe cost saving after 8 years compared to PPI maintenance therapy

GERD& Barrett’s esophagus

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

Clinical data• Pope et al (N Eng J Med-1980), complete regression of IM in 4/10 patients. Low et al (Am J Gastr-1999),Complete regression in 2/14 pt partial regression in 10/14 ptDisappearance of dysplasia in 4/14 ptDe Meester (Ann Surg-1998),Complete regression and loss of IM in 4.4%

Clinical data

• Ortiz and colleagues (Br J Surg-1996),Randomized 27 pt (M) + 32 pt (S)Follow-up 5 yearsRegression of IM: 2/27 pt of medical arm 8/32 pt of surgical arm. Mc Callum et al (Gast-1991). Katz et al (Am J Gas-1998)

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.

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

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

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

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.

Factors contributing to success of LNF

factors

• 1- typical GERD symptoms

• 2- well-respond to PPI therapy

• 3- abnormal 24 pH study

• All 3 factors = 95-98% success of LNF

• Only 2 factors= 70-80%

• Only 1 factor = < 50%

Summary

• PPI is still the first line of GERD therapy • Laparoscopic Nissen fundoplication remains an Laparoscopic Nissen fundoplication remains an

effective anti-reflux measure at 10 years effective anti-reflux measure at 10 years • Resumption of anti-secretory Rx not a measure Resumption of anti-secretory Rx not a measure

of surgical failure of surgical failure • Recurrence can be treated effectively with Recurrence can be treated effectively with

laparoscopic revision laparoscopic revision • Severe GERD symptoms and response to PPI Severe GERD symptoms and response to PPI

are good indicators of symptom outcomeare good indicators of symptom outcome

Final word

• Let the GERD patient decide about the treatment option

• What about YOUNG
