LapSleeve: STANDARD TECHNIQUE [Last Validation Dec 31, 2015 - PSJMC]

Access to Standardized PREFERENCE CARD

All Service Technical Variations MUST BE reported via OLP

STEP 1: POSITION AND PRE PROCEDURE CHECK

- Insert 2 peripheral IVs - Large Bore / CVP is not possible.

- Place stools on Right and Left Side of the patient.

- Position Patient as follows:

STEP 2: ANESTHESIA - INDUCTION - ETI

- IV Injection: 5000 U Heparin SC

- Patient to be fully paralyzed.

- Insert COVIDIEN TUBE.

STEP 3: PNEUMOPERITONEUM CREATION

- Verress Needle - MAX IAP: 15 mmHg

STEP 4: TROCARS PLACEMENTS

- Explore Intra-abdominal cavity [ 30 Deg 10 mm Telescope]

- Insert Hepatic Retractor, deploy and retract the left hepatic lobe.

STEP 5: Taking down - Mobilizing the Greater Curvature

- Using the SONICISION, take down the greater curvature all the way to the GI junction. TAKE GREAT CAUTION WHEN APPROACHING THE SPLENIC HILUM.

STEP 6: Checking the intra-gastric tube placement

- The intra-gastric tube should be hugging the lesser curvature and the tip placed at about 6 cm from the pylorus.

STEP 7: Creating the Gastric Sleeve

- Using the ENDOGIA XL start transecting the antrum with a PURPLE 60 cm cartrige.

Reinforced Covidien Cartriges are NOT routinely used for this procedure.

The transection is carried all the way to the GE junction using the following guidelines.

1. The stapler should NOT be fired too close or too tightly to the gastric tube.

2. Be attentive not to transect too tighthly around the GE junction - be generous and do not fire the stapler is the fatty tissues.

3. Always locate the anterior vagus nerve at all times.

4. Be certain the posterior gastric wall is free of adhession.

STEP 8: Check the hemostasis of the gastric staple line.

The gastric staple line can bleed in a delayed manner i.e. a few hours post procedure. unsing at least 2 ENDOCLIP 10 mm M clip the entire staple meticulously clipping the visible blood vessels.

STEP 9: CREATING THE GASTRIC POUCH

An intra-gastric tuve is inserted by the anesthsiologist. The tip of the tube MUST BE IDENTIFIED in intragastric position. Once identified, the balloon in inflated with 30 cc of normal saline. The inflated balloon is then pulled back snug against the GE junction.

An additional trocar is inserted in epigastric positioin [12mm VERSASTEP].

A passage is created with the blunt grasper between the lesser curvature of the stomach and the vagus nerve. The vagus nerve is left intact. The passage is enlarged with the same grasper to a size of 4 mm into the lesser sac.

The ENDOGIA UNIVERSAL loaded with a PURPLE 60 mm cartridge is inserted in the abdomen via the most lateral 12 mm trocar and thelargest jaw into the passage, into the lesser sac. The stapler should be oriented so the posterior aspect of the "to-be-created" gastric pouch is larger than the anterior aspect. The superior aspect of the cartridge should be against the anterior aspect of the GE junction. The cartridge is closed and the stapler fired slowly.

The stapler is reloaded with now TAN 60 mm cartridges and fired to the greater curvature around the balloon. The balloon is used as a calibrating device.

CAUTION: It is at times safer to create a triangular gastric pouch extending toward the spleen versus a totally circular gastric pouch around the balloon.

A holding suture is placed on the lesser curvature of the gastric pouch [SILK 0] with the ENDOSTICH INSTRUMENT.

The anesthesiologist will push the tip of the gastric tube forward creating some counter tension in the gastric pouch and exposing the tip of the tube to the surgeon.

Using the SONICISION device a small 3mm gastrotomy is placed at the tip of the tube closest to the lesser curvature. An enterotomy is then created 5 cm from the tip of the Roux Y Limb exactly at the anitmesenteric border.

The ENDOGIA loaded with a TAN 60 Cartridge is inserted via the epigastric 12 mm trocar . The staple bearing large jaw is inserted first in the enterotomy; the stapler is then moved cephalad and the smaller jaw is inserted into the gastrotomy. Using a grasper from the most lateral 12 mm trocar, the holding suture is retracted and used to guide the stapler.

The stapler is inserted up to the MARK 3. Expert baraitric surgeons can eventually decrease the size of the gastroenterostomy by inserting to MARK 2.5 or 2.

VERIFY THERE IS NO EXCESSIVE OR CORRECTABLE [OMENTAL TRANSECTION] TENSION OF THE ANASTOMOSIS BEFORE FIRING.

The stapler is fired slowly and removed.

Anesthesia will advance the gastric tube through the anatomosis into the Roux Y Limb and will stent the anastomosis during the suturing phase.

The anterior aspect of the open anastomosis is then sutured closed with the ENDOSTICH INSTRUMENT [Low experience surgeons - use SILK 0 / Experts can use ABSORBABLE SUTURES].

Once the anastomosis is closed, the tip of the anastomosis is reinforced with a SILK suture incorporating an omental piece of fat as an omental patch.

STEP 10: TESTING THE ANASTOMOSIS

A bowel clamp is placed on the ROUX Y limb distal to the gastro-enterostomy. The gastro-enterostomy is submerged under saline.

The Roux Y limb is inflated with air via the aspiration port and tested for air leak.

The gastric tube is removed. The bowel clamp is removed.

STEP 11: Placing a Blake drain

A Blake drain is left in the abdomen by the gastro-enetrostomy.
