LAP-BAND
Overview
Our program is recognized nationally as a Bariatric Surgery Center of Excellence. We offer laparoscopic Roux-en-Y gastric bypass, laparoscopic adjustable gastric band (LAP-BAND) and revisions of failed bariatric operations. We believe that an operation is just one part of the successful treatment for morbid obesity in those people who choose surgery. We use a comprehensive team approach to help our patients also make the behavioral changes necessary for long-term success.

Your Surgeon
Our surgeons dedicate a substantial amount of their surgical practices to bariatric surgery. They are experienced advanced laparoscopic surgeons. They will share parts of your evaluation and preparation for surgery as well as for your follow-up care, but only one will do your operation. In general, the surgeon who evaluates you during your first appointment will be the surgeon who does your operation, unless you agree to a switch before surgery. You may request a specific surgeon but please do so before getting a date for your first appointment. If we have to reschedule your appointment it could delay your evaluation.
Morbid Obesity
According to insurance data 20% of the American population is obese. Morbid obesity, however, is when a person is greater than about 100 pounds over their ideal weight. In this weight range, obesity becomes a serious medical condition, one that substantially shortens a person’s life expectancy. Morbid obesity causes or contributes to many other health conditions and illnesses (such as diabetes, high blood pressure, high cholesterol, heart disease, gastroesophageal reflux (GERD), urinary incontinence, arthritis, gallbladder disease, female infertility). For some of these conditions, the only hope of improvement or control is through sustained weight loss. Unfortunately, even well organized and monitored diet programs fail to maintain weight loss by 2-3 years for over 95% of those people who use them. Surgery has been shown in many published studies to be the only successful method of achieving lasting weight loss for most people with morbid obesity.
Program Objective
Each patient we evaluate wants to lose weight and keep it off. That is
our goal, too. Although we share each successful patient’s joy and improved
self-esteem, our primary interest is in prolonging life and preventing or
helping control the illnesses caused by morbid obesity. This is not cosmetic
surgery.
Our
program uses bariatric (weight control) surgery to enable weight loss and
long-term weight control. We take a team approach before, during, and after
surgery. No operation alone is a cure for obesity. But
the operation gives most patients better control of their food intake for the
rest of their lives. We expect our patients to stay in touch with us and
involved in the program for the rest of their lives, too. This helps us help
them by periodically (yearly after the second year) checking their weight,
eating patterns, exercise, blood tests, and anything else that can affect their
results. Not all patients will achieve the results they desire, but by selecting
our patients well and following their progress long-term, we can help most
patients reach and maintain healthy, realistic, and satisfying weight loss.

About the Operation (Laparoscopic Adjustable Gastric Banding: LAP-BAND)
Our surgeons are experienced laparoscopic surgeons. They do these operations laparoscopically through five tiny abdominal puncture wounds. Laparoscopy speeds recovery, avoids some of the problems associated with the incision required by the usual open abdominal approach, and provides a better cosmetic result. The chances of you requiring an incision during surgery is extremely small. Whether done laparoscopically or open, however, the operation is done the same way on the inside and should achieve the same long-term results.
Changes in Eating After the Operation
Lap-Band surgery forces eating and lifestyle changes. A patient’s ability
to eat “normal” amounts of food is removed by properly adjusting the band. For many people with
life-long obesity, for the first time in their lives they feel what it’s like
to be full and not interested in eating more. Unlike after a gastric bypass,
Lap-Band patients absorb the food they eat normally, so vitamin supplements are
usually not necessary. Eating and meals have strong family and social significance for many
people, so the dietary restrictions required of a Lap-Band can affect more
people than just the patient. Health problems caused by obesity usually
gradually improve or
even disappear.
After the first month, patients slowly advance to eating soft, then
regular foods. Some people will not be able to eat red meats, non-toasted bread,
fruits with peels on them, or some raw vegetables after this operation.
Lap-Bands
don't cause the Dumping Syndrome that discourages gastric bypass patients from
eating sweets.
A typical restaurant meal after full recovery will be the size of a
child’s portion. We encourage all
our patients to have their life-long follow-up with us at the Bariatric Surgery
Center.
Anticipated Results
The
average patient will lose 60-70% of his or her excess body weight (amount
over their ideal body weight) over the 3-5 years. Weight loss is slower but
steadier than after a gastric bypass. Unlike a gastric bypass, though, a
Lap-Band is adjustable so weight loss continues for a longer period of time. Someone 200 pounds overweight
can lose 120-140 pounds or more. Lap-Bands don't appear to have as much weight
regain as gastric bypasses. Those who exercise
regularly can expect better results than those who do not. Those who adhere to a
healthy diet will do better long-term. Those who stay involved with
the Bariatric Surgery Center and its Support Group will probably also do better
than those who do not.
The Lap-Band should be seen as a tool the surgeon provides to
help curb appetite on a long-term basis. Success still depends on the patient,
though. Fatty and
fried foods (such as corn and potato chips), alcohol, and snacking
(“grazing”) throughout the day can greatly increase calorie intake and cause
weight regain despite the band. This is why we believe in a life-long program
through which we periodically reassess each patient’s weight and food intake
(among other important measurements) and help each achieve and maintain his or
her goals.
Serious Risks Immediately After Surgery
 |
Pulmonary
embolism – This occurs when blood clots form in the large veins of the
legs and pelvis, break lose, and travel to the heart and lungs. We
administer a gentle blood thinner while in the hospital, but the best way to
prevent this is to get up and walk. Blood that’s kept moving through
activity usually won’t clot. |
|
Death
[0.1% (1 in 1000 operations)]. This occurs due to a complication of the
operation or pre-existing health problem, possibly an injury to another
organ, a pulmonary embolism or a heart attack. Those patients who have
serious complications from their obesity (such as severe heart or pulmonary
disease or poorly controlled diabetes) are less able to recover from
complications and less likely to survive if a serious one occurs. |
| Bleeding
– Patients
rarely require a blood transfusion after Lap-Band surgery, but any
operation can occasionally cause enough bleeding to require re-operation to stop. We
respect the wishes of patients who refuse blood transfusion, but as a
result, they will be more likely to require an
emergency re-operation that could be avoided by giving a transfusion. |
|
Atelectasis/pneumonia
– It can be uncomfortable to take deep breaths and cough immediately after
surgery. When patients fail to do so, portions of their lungs tend to
collapse (atelectasis). This
can cause fevers and fast heart rates mimicking more serious complications
and can lead to pneumonia, itself a potentially serious problem. The best
way to avoid this is to deep breath, cough, and get out of bed for walks in
the hallway and after going home. |
| Nausea - Some patients feel nauseated after surgery, but it's less likely after a Lap-Band than after a gastric bypass. Regardless of nausea, you must take in enough fluid and nutrition to stay healthy. Fortunately, the nausea resolves on its own. |
|
Vomiting – This is most likely to happen after the band is inflated (tightened). If it persists, the band might need to be loosened. Even with a well-adjusted band, vomiting can happen when over-eating or eating foods that have a history of causing you trouble. |
|
Re-operation – Our surgeons do not hesitate to re-operate on patients who are not progressing well the first few days after surgery. If they cannot find an acceptable explanation for a rapid heart rate or if a patient is not looking or feeling as well as they think they should, they will put the laparoscope back in at a second operation to make sure there has not been a leak or other problem. Complications that are detected early, before a patient gets critically ill, can more often be managed easily without major setback. Fortunately, this situation arises infrequently after Lap-Band surgery. |
Long-Term Risks After Surgery
| Vitamin deficiencies - Lap-Bands don't create vitamin deficiencies as long a patient maintains a healthy diet. |
| Gallstones - Some patients form gallstones during the period of rapid weight loss. Most of the time gallstones don't cause problems, but in some people they can cause recurring upper abdominal pain, often under the ribs on the right side, sometimes going through to the back. When this happens, we remove your gallbladder laparoscopically, often on an outpatient basis. Gallstones are less likely to form after Lap-Band than after gastric bypass surgery because weight loss is more gradual. |
| Slippage - This occurs when a portion of the stomach slides up underneath the band. We put in stitches to prevent it from happening but it occasionally does anyway. Slippage can cause difficulty eating, vomiting and upper abdominal pain. The diagnosis would be made by endoscopy or x-ray after band adjustment doesn't help. Treatment requires laparoscopic surgery to replace the band. |
| Erosion
- This occurs when the band gradually moves from being wrapped around the outside
of stomach to being partially inside the stomach. The symptoms can be
similar to a slippage. Treatment requires laparoscopy to remove the band,
possibly with conversion to a gastric bypass. |
|
Hanging
skin – Many patients retain some extra, loose skin on their abdomens
(sometimes also arms and thighs) after
they lose weight. Often the only way to get rid of this extra skin is to
remove it surgically. The bariatric program has support from some local
plastic surgeons, but this operation (panniculectomy) is considered by many insurance companies to be cosmetic surgery and, therefore, often won’t be
covered. |
|
Dissatisfaction with the operation – Not everybody achieves his or her desired weight-loss results. If our best efforts at adjusting a Lap-Band doesn't enable weight loss, conversion to a gastric bypass could be considered. Others lose weight but don't like the dietary restrictions, in which case the band can be loosened. Removing a Lap-Band is not difficult, but we would doing that only for medical reasons. |
| Unlike gastric bypass surgery, which has been around since the 1960s, Lap-Band surgery was approved by the FDA for use in America just five years ago. It's been the most popular bariatric operation in Europe and Australia for longer than that, but nobody knows how these will hold up over a patient's lifetime or whether they will cause problems in the future. Fortunately, Lap-Band replacement or removal is usually not demanding or high-risk surgery. |
The Evaluation
Process
Many patients find the program’s evaluation process slow and drawn-out.
This is not unique to our program. Waiting lists are long at almost all centers
offering a comprehensive team approach to bariatric surgery. Most of the wait is
simply because our surgeons can do only so many operations in any given week.
Part of the slow pace is because we want it that way to allow time for us to get
to know each patient and to allow each patient to become entirely familiar with
our team, our program, the operation, and the necessary life-long dietary
changes after surgery. We realize this rigorous approach is difficult for those
traveling from outside the Portland area, but we don’t know a safe way to cut
corners.
First contact – Our nurses review each referral to make sure the BMI is appropriate to qualify for surgery or even an appointment. We mail out information packets for the patient and forms to be filled out and returned to us (or completed online) so we can gather information from primary care providers and any other physicians involved. We also begin work on insurance approval. Patients should also start the tedious insurance approval process. Some insurance companies require documented efforts at supervised dieting and exercise for 6 months within the 1-2 years before weight-loss surgery. Be sure you know your policy.
First
Bariatric Surgery Center appointment
– A patient meets for about an hour each with our dietitian, therapist, and
one of our surgeons. These separate evaluations are important and necessary. A personal or local
therapist or dietitian can’t substitute at this point in the evaluation.
Because scheduling the whole team is complex, it sometimes requires two visits
to complete the "first appointment." The
team discusses each patient individually and makes an initial determination
about the appropriateness of surgery and need for any further testing or
consultation. Each patient will be instructed to complete sample menus and to
prepare meals from the menu for the first month after surgery. The wait for the
first appointment will probably be the longest delay in the process.
Information Session - This is held at 8:00 a.m. on the day of your first appointment with the surgeon. One of our nurses and a surgeon will discuss the program and the operations. It's an opportunity to ask questions that might help you decide which operation sounds best for you (Gastric Bypass or Lap-Band) or to change your mind if you've already picked an operation. The surgeon who gives this presentation and evaluates you during your first appointment will also be the surgeon who does your operation, unless you agree to a switch before surgery (which could also create some delay).
Second
appointment
– Usually 4-6 weeks after the first. Each patient meets with the dietitian to
review the sample menus and to review the food items prepared from the menu. Our
therapist will discuss any issues or concerns that may have arisen about the
upcoming surgery. The surgeon will discuss the details of the operation again. After this visit, a date for surgery will
often be assigned. That
wait can be another 1-3 months, depending on your insurance.
Support Group attendance – Attendance of at least one monthly Open Support Group or Lap-Band Support Group meeting is required before surgery can be scheduled.
Pre-admission
interview
- An evaluation by the anesthesia staff before any major operation. It
is required of many, but not all, Lap-Band patients. We’ll also obtain some blood tests, including nicotine levels for some
patients.
Surgery
– Always performed at Maine Medical Center.
Most patients will arrive 1-2 hours before surgery and either go home the same
day or stay in the hospital overnight.
Three-month visit - Usually the last visit with the surgeon and therapist.
Long-term follow-up - Our nurses and dietitians continue to assess overall progress and obtain necessary blood tests at 6, 12, 18, and 24 months. Visits are once a year after that, as long as you're doing okay. It is important to bring a three-day food intake record to these appointments for review by the dietitian. To maintain our designation as a Center of Excellence, we must maintain 5-year follow-up on %75 of our post-op patients. Please help us do this by staying in touch with us every year.
Lap-Band adjustment visits - We'll adjust your band as often as it makes sense. If you're losing weight too quickly, having heartburn, trouble eating and vomiting, it makes sense to loosen it. If, on the other hand, you're hungry all the time, able to eat normally and not losing weight, it's probably time to tighten it. Don't hesitate to call us. For simple adjustments, your appointment should be a quick one with one of our nurses.
Support Groups
Support Group meetings are a way for new patients to meet old ones. They
provide an opportunity for people to discuss obesity, how it has affected their
lives, and how surgery has affected (or might affect) their lives. The Open
Support Group (any bariatric operation) and Lap-Band Support Group (Lap-Band
only) meet under the supervision of Bariatric Surgery team members but is really time for our patients and potential patients to use as they want.
Attendance is limited to those people who have already had surgery or are
considering it, their families, and support people. See our Support Group
Schedule for times and locations.
Exclusion Criteria
We will delay scheduling surgery or
even cancel a scheduled operation for any patient who doesn’t meet our minimum
standards or who fails to follow through with instructions. Although we are
compassionate to our patients’ problems, we sometimes must exclude people when
we feel the operation is not right for them. Because we screen our referrals so
closely, this doesn't actually happen very often. Examples of possible obstacles
to surgery:
|
BMI too low. |
| A large hiatal hernia or previous Nissen fundoplication requires a gastric bypass instead of a Lap-Band. |
|
Failure
to stop smoking 3 months before surgery (blood tests for nicotine will be
checked prior to surgery). |
|
Failure to lose weight when instructed to (not usually required). |
| Failure to follow through with assigned therapy sessions between appointments. |
|
Failure
to attend a support group meeting before surgery. |
|
Failure
to comply with sample menus and diet assignments or understand
post-operative diet. |
|
Failure
to keep a scheduled pre-operative appointments without advance notification.
We are concerned that this situation might identify the patient who won’t
follow through with post-operative visits and instructions. |
|
Lack of
commitment to the life-long dietary and lifestyle changes required for
long-term success. |
| A patient loses weight during the evaluation and decides to continue diet & exercise instead of surgery. |
| A patient loses interest. |
Summary
Morbid obesity is a serious health condition that contributes to or
causes many other medical problems and significantly shortens life expectancy.
Diet approaches to weight loss in this population usually fail. The
only well researched and tested method of long-term weight control for the
morbidly obese is surgery. Our goal is to offer successful surgery to as many
appropriate candidates as we safely can. Remember, no method, including
surgery, is certain to produce and maintain weight loss. Success is achieved
only with each patient’s full cooperation and commitment to dietary and
lifestyle changes and medical follow-up.
