Benefits of Laparoscopic Surgery
• Minimal post-operative pain• Day-case or only overnight hospital stay• Quick return to normal activities• Less impairment of pulmonary function• Less immune suppression• Less blood loss• Minimal risk of wound infection or hernia

• Over the counter drugs: £ 100m

GORD Predicts Oesophageal Cancer

GORD Treatment
• Full-dose PPI for one or two months
• Recurrent symptoms: PPI at lowest dose
to control symptoms, with minimal repeat
prescriptions
• Treatment “on demand” basisNICE, 2005
![Page 9: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/9.jpg)
PPI Maintenance Therapy: Limitations
• Nocturnal acid breakthrough• Twice-daily dose for severe GORD• Insufficient control of regurgitation• ? Interaction with H.pylori• Continuing biliary-pancreatic reflux• ? Long-term (> 10 years) safety• Cost
![Page 10: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/10.jpg)
PPI Maintenance Therapy: Limitations
• Recurrent symptoms in 20-30% of patients on regular maintenance, low-dose PPI
• Full dose PPI needs to be maintained for complicated GORD (NICE, 2005)
• PPIs did not eradicate need for caution and restraint (NICE, 2005)
• Most patients want to dispense with need for long-term PPIs (NICE, 2005)
![Page 11: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/11.jpg)
Anti-Reflux SurgeryNICE Guidance, 2005
Surgery is not recommended for the routine
management of uncomplicated GORD, BUT
individual patients whose quality of life
remains significantly impaired may value this
form of treatment.

Laparoscopic Anti-Reflux SurgeryIndications
• Long-standing GORD – PPI dependance• Poorly controlled GORD • PPI intolerance• Respiratory manifestations• Complications – erosive oesophagitis,
stricture, Barrett’s oesophagus• Regurgitation • Large hiatus hernia
![Page 16: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/16.jpg)
Laparoscopic Anti-Reflux Surgery
• Keyhole (One 12mm and five 5mm incisions)• Obesity is not a contra-indication• Usually overnight stay• Stop PPI immediately• Majority have immediate, complete
symptom-control • Global improvement in well-being
![Page 17: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/17.jpg)

Laparoscopic Anti-Reflux SurgeryPost-operative Issues
• “Sloppy” diet for initial 3-4 weeks
• Problematic dysphagia is rare and indicates a mechanical problem
• Need for supplementary PPI is uncommon
• Is recurrent dyspepsia due to reflux?
• Gaseous bloating: common side-effect
![Page 19: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/19.jpg)
Laparoscopic Cholecystectomy
• Diagnosis: USS versus MRCP• Increased severity of inflammation in
obese individuals• Value of routine intra-operative
cholangiogram: “silent” stones in 5-10% with normal USS and normal LFTs
• Laparoscopic CBD exploration: quick recovery and avoids post-op ERCP
![Page 20: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/20.jpg)
Intra-operative Recognition
Should primary repair be attempted?
![Page 21: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/21.jpg)
Laparoscopic CholecystectomyPost-operative Issues
• Unusually severe abdominal pain: powerful marker of bile leakage
• Prolonged recovery time: often related to inflammation and spillage
• Inflammation around umbilical incision• Exacerbation of reflux symptoms• Missed bile duct stones and delayed
stricture
![Page 22: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/22.jpg)
Laparoscopic Groin Hernia Repair
• NICE guidance (Sept. 2004)
• Laparoscopic approach is preferred option for recurrent hernia or bilateral hernias
• Laparoscopic approach should be offered for primary, unilateral hernia
![Page 23: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/23.jpg)
Laparoscopic Groin Hernia RepairBenefits
• Keyhole (One 1.5cm & two 5mm incisions)
• Minimal pain
• Day-case operation
• Immediate return to normal activities
• Do not drive – 1 week
• Do not go to the gym – 1 month
• Simultaneous repair of “silent” hernias
![Page 24: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/24.jpg)

Laparoscopic Groin Hernia RepairPost-operative Issues
• Common features: Bruising, Seroma
• Worrying features: Haematoma, Infection
• Recurrence: ? superior to open repair
![Page 26: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/26.jpg)
Laparoscopic Ventral Hernia Repair
• Keyhole (One 12 mm & two-three 5 mm incisions)
• Avoids large incision & wound complications• Particular valuable for:
– Obese patients– Recurrent hernia
• Usually 2-3 day hospital stay• Greater security than conventional repair• Simultaneous repair of silent defects
![Page 27: Endoscopic Surgery What the GP Needs to Know](https://reader035.vdocuments.us/reader035/viewer/2022062323/568160fd550346895dd039f7/html5/thumbnails/27.jpg)
Laparoscopic Ventral Hernia RepairPost-operative Issues
• Prolonged-pain
• Seroma
• Haematoma
• Infection
• Uncomfortable subcutaneous suture-knots
• Missed enterotomy – rare but serious

Laparoscopic Obesity SurgeryNICE Guidance (Reviewed 2005)
Recommend for morbidly obese patients• BMI>40kg/m2
• BMI>35kg/m2 with co-morbidityIf criteria are satisfied:• Age>18 years• Non-surgical measures have been tried• Understands need for long-term follow-up• No psychological or clinical contra-
indication

• Results are highly surgeon-dependent
• Best results reported from high-volume,
high-quality centres
• Expertise and technology
• Particularly important to offer prompt, high-
quality service for problems or failures
