Revisional Bariatric Surgery

There are different surgery options, and Mr Purkastha can talk you through how each surgery works, and which would be the best option for you. 

The revisional surgeries we offer are listed below, with the average weight loss achieved for each surgery

Gastric Sleeve – up to 75% of excess body loss in the first year after surgery

Gastric Bypass – up to 80% of excess weight loss in the first 18 months after surgery

The above surgeries work by increasing the amount of restriction on the stomach size and deliberately increasing malabsorption of food so fewer calories are absorbed by the body. This can help correct previous procedures which may have been ineffective with aiding weight loss goals.

The positive health outcomes from revision include more significant weight loss and the reduction of conditions related to increased weight. This includes but not limited to:

• Type 2 Diabetes
• High Cholesterol
• High Blood Pressure 
• Heart Disease 
• Stroke
• Mobility issues
• Joint pains
• Cancer
• Sleep Apnoea
• Infertility

Weight loss and better health can also improve the quality of your life and mental health, boosting self confidence and opening up new doors for how you want to live your life

Professor Puraksyastha will walk you through the preparation steps in the weeks leading up to your revision surgery. The support you are given is tailored to you, following full metabolic, dietetic and psychological assessments. This is to ensure the best preparation and outcomes possible.

Our specialist dietitian will help you to prepare for your revision surgery by undergoing a pre-operative liver-reduction diet lasting two weeks. The diet is low in fat and moderate in protein and low in calories, providing approximately 800-1000 kcal per day. The aim of the pre-operative diet is to shrink your liver meaning it can be moved more easily, making the operation safer. In the 24 hours before your surgery, you will be required to restrict your food and drink intake. 

Our specialist psychotherapists will also help you to be best prepared for your surgery, ensuring you have the psychological support to ensure best outcomes.

Dietary changes

There are three stages of texture modification diet following surgery, starting with a liquid diet and gradually building this back up to a long term, solid textured food.

Your specialist dietitian will help explain and guide your through the post-operative diet which follows the below stages:

• liquid diet (10 days)
• puree diet (3-4 weeks)
• soft diet (for around 6 weeks)

This is followed by a lifelong healthy, high protein diet of a normal solid texture from 12 weeks onwards.

Fluid intake remains important and you should aim to drink 1.5 litres a day.  Avoid high calorie fluids including hot drinks made with sugar and fizzy drinks as these can cause bloating and discomfort.

Alcohol should not be taken for three months after surgery and after this time in moderation after food.  

Lifestyle changes

Exercise –  After surgery we advise you to move around as much as possible and ensure that you don’t get dehydrated.  Exercise should be gentle for the two months –  i.e. swimming, walking, cycling. No heavy lifting or weight training for at least eight weeks

In the long-term increased activity levels are needed alongside a reduced dietary intake for optimal and sustained weight loss after bariatric surgery.

Driving – You should not drive for the first two weeks following surgery and contact your insurance to find out what their guidelines are.  

We suggest that when you are ready to drive that you ask a family member or a friend to drive you to a quiet street where you can attempt an emergency stop. If it feels comfortable then it is fine for you to drive.

Travel – We advise that you do not take a long haul flights for 8 weeks following your surgery

You can take flights of no more than 2 hours duration from two weeks after your surgery

Pregnancy – We advise you to avoid pregnancy for 2 years after surgery. Oral contraception can be restarted 1 month after surgery

Smoking – It is strongly advised to quit smoking in the long-term as this can undo the positive health outcomes from surgery, and increases risk of ulceration in the gastric pouch, chest infections, cancers and heart disease.

After your recovery period has ended, you can start to enjoy the lifestyle changes that come about from better health and increased mobility associated with Gastric Sleeve surgery.

Your aftercare package includes prolonged support from Mr. Purkayastha and your specialist dietitian, as well as the wider Surgical WeightMatters team. 

You will have in-person follow-up appointments with Mr. Purkayastha arranged 7-10 days, 3 months, 6 months and 12 months after surgery with the option of additional follow-up appointments to check in with your progress. 

You will have several post-operative appointments with your specialist dietitian as well, which are spread over 2 years after your surgery and tailored to suit your needs.

There is no limit to how many sessions you can have with the Surgical WeightMatters team. We are with you every step of the way to ensure the best support and outcomes possible.

My Purkayastrha will take time to talk you through the risks involved with revision surgery and ensure you are fully informed before deciding which option you wish to have. Revision surgeries are usually more complicated due to the previous surgical work that will have been done on the stomach area. As a result, the risks are increased.

Every effort ensures these risks are avoided, and Mr Purkayastha is an extremely experienced revisional bariatric surgeon. However, the short and long-term risks involved with revision surgery are as follows:

Short-term risks:

• Pain 
• vomiting
• Bleeding
• Infection of the wound
• Adverse reactions to anaesthesia
• Blood clots
• Breathing problems
• Leaks from the cut edge of the stomach
• Potential complications from nutritional deficiencies
• Dumping syndrome 

Long-term risks:

• Gastrointestinal obstruction
• Hernias
• Gastroesophageal reflux
• Low blood sugar (hypoglycemia)
• Malnutrition, food intolerances or Dumping Syndrome
• Vomiting
• Blood clotting
• Stomach ulcers
• Barrett’s oesophagus

Weight regain, if diet and lifestyle changes are adhered to lifelong habits

Complications during surgery can result in elective or emergency medical or surgical (reoperation) treatment.
