Presentation Overview:

The SADI/SIPS procedure is a simplified version of the classic Biliopancreatic Diversion by Duodenal Switch and Sleeve Gastrectomy (DS). The difference merely resides at the duodeno-jejunal anastomosis: a Roux limb for the DS procedure, versus a Billroth II construction for the SADI/SIPS. The advocates of the SADI/SIPS claim a reduced risk of postoperative obstruction by internal hernia despite a policy of non-closure of Petersen space. The difference in duodenal anastomosis implies a more dangerous situation in case of leak for the Billroth II type of procedure, because the duodeno-ileal loop anastomosis precludes the use of stents. The Roux en Y construction causes different physiologic responses in terms of glucose absorption, which may result in enhanced activity on type 2 diabetes mellitus compared to the SADI/SIPS. In case of protein malnutrition or excessive weight loss, the limb lengths can be altered in both types of procedures, but changes may be finer tuneable with the DS.

In conclusion, both procedures have their pros and cons. Randomized prospective clinical studies are mandatory.

He is a prolific author, is co-editor for the "Obesity Surgery" journal and member of the editorial board of "SOARD".

Presentation Overview:

Intestinal obstruction is one of the most dreaded complications after bariatric/metabolic procedures, and DS is no exception. Obstructions can occur early (i.e. within 30 days postoperatively) or late. Because in the patient with obesity symptoms may be less obvious than in normal weight individuals, the threshold for intervening surgically should be low, because obstruction may affect the bypassed part of the intestine hence cause a “blow-out”. Blow-out may be a bigger threat than with gastric bypass because the blind ending segment is the duodenum, which is a much less compliant structure than the stomach.

Concerning the cause of the obstruction after DS, several conditions exist: adhesions, abdominal wall hernias including trocar hernias, rare causes such as bezoar, and, finally and importantly, internal hernias. Concerning the latter, careful closure of Petersen’s and of the mesenteric defect at the jejuno-ileal anastomosis are of the utmost importance to prevent this potentially lethal complication.

Phillippe Topart, MD

Dr. Philippe Topart, MD, graduated from Brest University, France in 1992. After serving as assistant professor of surgery and consultant surgeon there, he moved to private practice. He is part of six (6) associates at clinique de l’Anjou, Angers, France. Dr. Topart devotes his activity exclusively to bariatric surgery. He and one of his associates perform 400+ laparoscopic procedures a year. His practice includes sleeve gastrectomy, gastric bypass and transit bipartition and he has been performing biliopancreatic surgery for 15 years with a significant number of conversions from other bariatric procedures. Dr. Topart is a member of the French Academy of Surgery and of the editorial boards of the journals Obesity Surgery and Surgery of Obesity and Related Diseases.

Presentation Overview:

Biliopancreatic diversion is a powerful weight loss procedure which allows for a 75% excess weight loss and control of comorbidities on the long term. Revision rates for excessive malabsorption ranges from 0.5 to 4.9% and 3 to 18.5% after BPD/DS and BPD respectively. Revisions increase common channel by up to 150 cm. Reversal is necessary in 0.2 to 7% of cases with an increased risk when the common channel is ≤ 50 cm. In most instances, reversal (of the malabsorptive component only) is indicated after the revision failure. Indication for revision of the alimentary and common channels length is essentially based on albumin and prealbumin levels. Although there is no clear definition of malnutrition revision must be discussed when serum albumin and prealbumin levels are <30 g/L and <0.20 g/L  respectively. In most instances these biological abnormalities are associated with multiple vitamin and micronutrient deficiencies. Clinically a % of excess weight loss ≥ 100% represents a major risk of malnutrition. Additional signs are an ongoing weight loss as well as limb oedema (Kwashiorkor). Although low levels of serum albumin and prealbumin (between 30 and 35 g/L and 0.15 and 0.20 g/L) could be regarded as normal during the first year after surgery, stabilization of the weight loss with a return to close to normal values are expected between 12 and 18 after surgery. A proximal, side- to-side anastomosis between the biliopancreatic and alimentary limbs is the preferred option. Most reoperations are performed within 2 years of the initial procedure and for protein malnutrition in about half of the cases. Other indications are based on excessive digestive side effects (diarrhea).

Biliopancreatic diversion can be relatively easily revised to control excessive side effects and protein malnutrition. In several cases, depending on the severity of the malnutrition, a prior feeding jejunostomy can be required rather than other methods of renutrition (TPN, nasogastric feeding tube) which are often not as effective. Altough techically easy to perform the revision in malnourished patients carries the risk of postoperative leakage with devastating consequences and a correct nutritional status must be obtained before revisional surgery. After biliopancreatic diversion, close monitoring must be observed with regular blood checks every 3 months at least within 2 years of the initial procedure to diagnose malnutrition early and avoid liver failure. Blood checks should be repeated every year to ensure a proper nutritional status as the risks may be encountered on the long term although this is relatively rare.

At the end of this presentation, participants should be able to define an adequate biological as well as clinical monitoring program and identify the need to revise biliopancreatic diversion.

Daniel Cottam, MD
Director, Bariatric Medicine Institute

Dr. Cottam has been an active researcher and surgeon in the field of obesity since 2000.  This first began with his work as a resident in Long Island, NY.  There were many publications of ground breaking work using flow cytometry to show how obesity was a chronic inflammatory state. 

During his fellowship Dr. Cottam continued publishing looking at neuro hormonal mechanisms of appetite control at the same time focusing in inflammatory components of appetite.  Once finished with his training his focus shifted to more clinically orientated basic science mechanisms of immune privilege and obesity.  It is Dr.  Cottam’s ability to initiate and sustain good clinical outcomes and follow up and database monitoring that will enable Dr. Thomas to have valuable data to analyze. 
 
Dr. Cottam’s clinical achievements include the introduction of Sleeve Gastrectomy (SG) as a accepted means of weight loss control with fewer complications than the current standards of gastric bypass and lap band.  He is now one of the few surgeons who have realized the SG limitations.  He has  pointed out the large standard deviations of the procedure and is working on mathematical models to predict long-term failure for individual SG patients.  Dr. Cottam was also the first in the United States of America  to perform a new procedure called the loop duodenal switch.  This procedure eliminates many of the complications seen in the gastric bypass and regular duodenal switch with similar weight loss results.  He is currently the principal investigator of a $600,000 grant looking at outcomes for this new procedure.

Dr. Topart is a member of the French Academy of Surgery and of the editorial boards of the journals Obesity Surgery and Surgery of Obesity and Related Diseases.

Presentation Overview:

Because obesity remains a chronic disease weight loss control remains problematic for some patients on the long term. Insufficient weight loss (percentage of excess weight loss (%EWL) < 50%) is observed in approximately 20% after Roux-en-Y gastric bypass (RYGB). For a number of them other procedures such as gastric banding and sleeve gastrectomy have already been performed before gastric bypass. Surgical revision can be performed by various procedures including malabsorptive techniques. Conversion to a biliopancreatic diversion with duodenal switch (BPD/DS) remains a complex technique which could not always be performed as a one-stage procedure when the gastric bypass was fully dismantled and concerted to a regular sleeve gastrectomy before completing the duodenal switch. Based on our experience in 26 patients we designed a technique called “hybrid sleeve”. This approach does not require to alter the gastrojejunal anastomosis of the gastric bypass. Instead, the alimentary limb is divided approximately 5-6 cm distal from the gastrojejunal anastomosis and after resection of the fundus of the gastric remnant this short segment of jejunum is sutured to the antrum. The biliopancreatic diversion with duodenal switch is then completed in an usual fashion with division of the duodenum, measurement of the 250 last centimeters of the ileum and a common channel of 100 cm. Finally, the rest of the alimentary limb of the gastric bypass (jejunum) is abandoned without a full reconstruction and the creation of a “double” Roux limb within this modified duodenal switch. 

At the end of this presentation, participants should be able to simpler and alternative technique to convert staged procedures leading to a gastric bypass into a biliopancretic diversion with duodenal switch in order to restore weight loss.

Mrs Annick Dallaire graduated from Laval University in nursing care in 1996. She began her career at Hull Hospital before being recruited by Quebec Heart and Lung Institute – Laval University, in 1998. She has an extensive experience in the bariatric field, including working on the intensive care unit, operating room, hospital floor, bariatric research unit and, for the last eight years, working at one of the busiest outpatient bariatric clinic in Quebec province.

Presentation Overview:

Over the last years, types of bariatric surgery have increased and are more accessible to the patient who need it. We know that no surgeries are perfect, they all have their pros and cons. It's also been proved that the preoperative selection, education and preparation of the patient has a major impact on the outcome of the surgery. Therin lies the importance of proposing the BPD-DS to educated and selected patients.

With the experience gained through follow ups of more than 7 000 bariatric patients during the last 30 years as well as 550 bariatric surgeries done each year (including 200 DBP-DS), the IUCPQ's bariatric team has perfected its evaluation criteria and the screening process for BPD-DS preoperative patients.

This session presents the indications for BPD-DS and describes the different criteria and also the exclusion criteria. The key role of each professional in the team for the evaluation of the patient will be described.

Learning Objectives:

At the end of this session, the participant will be able to :

1. Identify the indication for BPD-DS
2. Recognize common exclusions criteria for BPD-DS
3. Appreciate the importance of teamwork for patient assessment.
