Transumbilical 2-site laparoscopic Roux-en-Y gastric bypass: initial results of 100 cases and comparison with traditional laparoscopic technique. Lee Wj etal Taiwan
BMI 43 kg/m(2) (range 32-61), OT 144 minutes (range 95-160)The 2-site LRYGB group had a significantly
longer operating time and more blood loss than the traditional LRYGB group but less pain and better cosmesis.

Cosmesis has never been an issue in bariatrics
More patients with lower BMI, more interested in cosmesis
After weight loss, we’ve underestimated the privacy issues implied by the scars
Especially for younger female patients

Hiding the main scar, and possibly adding a tiny scar for the Nathanson, allows band patients to go to the beach, wear more revealing clothes and go on dates without having to explain all the scars
Keloid scarring is very troublesome for some patients, especially African Americans

Patient demandMarket share
To be honest, there’s been minimal patient demand
It’s fun to do this for people, as part of the overall care of the patient

TechniquesTechniques
Single upper abdo incision - to me this wastes the whole premise of doing it
I use an infra-umbilical incision
Learn to operate with hands almost in parallel - minimal triangulation

TechniquesTechniquesThe major decision is whether to use a 5 mm or a 10mm scope
It depends how good your scopes areI currently use a 12 mm port, place the band through the fascial incision, then put the port in
Crowding is magnified if you don’t use a Nathanson, and need another port for liver retraction.

TechniquesTechniques
For fundoplication I use a 10 scope in a 12mm port and 2 5mm ports
For Gastric bypass I do all the dissection using a 10mm scope, then switch to a 5mm scope to use the stapler

TechniquesTechniques
Try to use a scope with an end attatchment to reduce clashing. We use Stryker
Some use flexible scopes. I’ve found no advantage

TechniquesTechniques
It’s all about best use of the space at the umbilicus, as you have to operate with minimal triangulation
Offset port lengths really helpPut the ports at the very lateral ends of the wound. A small curved wound will stretch out flat.
A curved dissector is essential to go safely behind the esophagus.The Real Hand was best. The Ethicon band passer is a reasonable alternative

SILS Lap Band Techniques
Use both Allergan and Realize bandsAbout a 3: 1 ratioBoth work great Allergan easier to pass tubing and lock in this technique
The long tag on the Realize helps with retraction to expose the upper pouch

TechniquesTechniques
Mesh fixation of the Allergan port, Use a small disc of Marlex mesh sutured to the back of the port, and just lay the port on the deep fascia at the right hand end of the wound
Use applicator for Realize port
Minimal dissection of a pouch for the port
Must get down to fascia

It’s here to stayIt’s fun to doIt’s definitely more difficult, and harder to teach
It’ll never replace standard laparoscopy in the mainstream
It’s being driven by industry, with special SILS ports.
I don’t think you need them
