What is done is that the greater curvature of the stomach is freed from the tissues attached to it (known as the gastrocolic omentum) using a vessel sealing device like the Harmonic Scalpel or the Ligasure. This is the first step of the sleeve gastrectomy procedure, as well.

However, unlike the sleeve, here we do not use the stapler to remove 80% of the stomach. We merely imbricate/plicate the stomach using running stitches from above downwards, layer by layer, till most of the stomach is pushed inwards, creating a narrowing of the passage, and a tunnel along the lesser curvature, just like the sleeve.

Lap Gastric Plication

In the same vein, if someone wants to reverse the procedure, the stitches may be removed by laparoscopy (making this a potentially reversible procedure like the Lap Band), though this would neither be a good thing nor a great experience!

Some patients have significant reflux symptoms after LGP, as after the sleeve, as we have discussed before.

It is possible that the stitches may give way later and hamper the weight loss, but preliminary results, as presented in the recent International Conference of Obesity in Stockholm, show good results akin to the sleeve.

More info later!

This article discusses these issues. Please buckle your seat belts!

First things first, who doesn’t know what a sleeve (as this operation will from now on be called) is and what it is for? Please refer to our Procedures page and also search this site for many other articles on this popular weight loss procedure.

Normally, the weight loss expected out of the sleeve is in the whereabouts of 50-80 percent of excess body weight. This is usually achieved in the vicinity of one year and may go on till three years, after which time there is usually no inherent weight loss from the surgery. This does not mean you will stop losing weight after that time. You could lose weight if your diet and exercise plans are on the spot. But in practice, weight loss plateaus in and around the third year. A recent study from India published in the journal SOARD reports a nearly 75 percent weight loss of the sleeve in three years.

So, the weight loss curve hits a plateau at a point in time. In itself, this is a benefit, as sleeve patients would shrink to oblivion otherwise! So, now that the weight loss plateau is upon you, what to do?

(the stapling process proceeds towards the direction of the foodpipe/esophagus)

Before we answer this, let us eliminate one important cause of weight regain* after the sleeve: a residual fundus. This means that the upper baggy part of the stomach, which is the source of the hunger hormone ghrelin, has not been fully removed by the surgery (usually a technical error). If this is detected, it is bad news.

*The definition of this is taken to be a weight regain of 10 kgs from the nadir (bottom) of the weight loss curve.

In order to get the desired weight loss, re-surgery has to be undertaken. In such a case, we do one of the following:

1. Re-sleeve: using an endoscopic stapler, the extra fundus (the culprit) is excised. An option to create a narrower sleeve is also possible, but would mean more staplers, and higher cost.

2. Convert to a Roux-en-Y gastric bypass: especially if the patient is super-super-obese (BMI more than 60), where the sleeve is usually the first of a two-stage operative strategy. An alternative we can explore in the Western/Muslim/non-vegetarian super-super-obese patient is the Duodenal Switch (DS). The reason for this is that these patient classes usually eat enough proteins by way of meats. This is a very crucial consideration as the DS causes severe malabsorption of proteins and fats and can cause debilitating malnutrition in the vegetarian patient.

3. A banded sleeve. This adds an additional restrictive element to the sleeve, but has the disadvantages that a Lap Band normally carries (which is another full article). In short, high explantation rates, erosions, prolapse of gastric mucosa, esophageal dilatation, etc.

In a special section on sleeve gastrectomy published June 2010 in the journal Surgical Laparoscopy, Endoscopy & Percutaneous Techniques, I quote:

Similar to the banded gastric bypass, a band can also be placed in SG performed as ‘‘primary banded sleeve gastrectomy,’’ as published by Alexander et al. In this series of 27 patients, a band of 6 cm length made of biologic tissue (AlloDerm) was placed approximately 6 cm below the gastro-esophageal junction.

This is same, but different, compared to the former “secondary” sleeve banding described by Greenstein.

In some cases, improper eating (large feeds, drinking colas and binge eating) can cause the gastric tube (sleeve) to become dilated. Though the initial surgery may have been perfect, the end result is similar to that of a residual fundus after primary surgery: inadequate weight loss, or an early weight loss plateau. This is the reason it is critical to screen patients before surgery for eating disorders and psychiatric conditions that make for unreliable post-op compliance (which means we don’t want to operate on patients who won’t listen to us, and are likely to screw up the results of surgery and give us a bad name).

Let’s get back to the originally asked question. If you underwent a gastric sleeve surgery, and there were no operation-related problems and you lost 70-75% of your excess body weight in, say, three and a half years, BUT you put back 5 kgs in the last few months, what to do?

First, we evaluate the stomach: is it dilated? Is there a residual fundus?

If there is no surgically significant problem, we must get back to basics.

Our strategy is simple:

1. Motivation: talk, talk and more talk. Help the patient understand how results should be the focus, not eating.

2. Eliminate processed foods, sugars, sweetened beverages, alcohol, and other such temptations.

3. Reserve grains as a cheat meal, not as a daily component of the diet.

4. Put some patients on a low-carb diet.

5. Careful food journaling and monitoring of nutritional intake. An online journal may be kept for free at www.fitday.com (or similar sites).

6. Fish oil capsule supplements: 1.8 to 3 grams daily (around 6-8 caps daily).

7. Activity guidance: walk, cycle, play, climb, skip. Don’t sit, slouch, drive, ride.

8.  Exercise: strength training with cardio, both HIIT and long-slow cardio.

Once we hit the system with renewed vigor, you will soon be back on track with weight loss!

Each time, I sigh. It means another ten minute lecture is due on my part. I have to teach an important lesson to the patient (not to mention the family) all over again.

So my lecture goes somewhat like this:

Why are you here? Because eating the way you do has led to a level of obesity that is dangerous to your health and even your very existence. You have suffered endlessly because of your obesity. You have lived through your own self-recrimination, the admonishment of your family, the chiding and teasing of your friends, and countless other miseries unique to the severely obese individual.

Eating the kind of foods the way you have been eating has caused you so many life-threatening diseases like diabetes, sleep apnea and hypertension. Eating sugars and junk has brought you to surgery as a last resort.

So why are you not looking further ahead to being leaner and healthier? Why are you looking back to eating the same kind of way that has made you what you are today? Look at this thing in perspective. You have a whole new life ahead. Plan on how you can make the most of this with your new-found health and look. Liberate yourself from guilt and misery. Focus! The goal is health and leanness, not food. Focus! Look, you are several trouser sizes down! Look, you look great in that new slim-fit T-shirt! Look, people are wide-eyed at your transformation. Look, your husband thinks you are beautiful again!

Don’t miss these achievements. None of this is possible if you think surgery is your destination. It is not. Surgery is your vehicle. It will take you where you would never have dreamed of reaching. But you will do so only if you keep sight of your goals. That is what is called FOCUS.
