Sleeve LeakA Tragedy of Unimaginable Proportions
• Sleeve gastrectomy severe complications: is it always a reasonable surgical option?
• Moszkowicz D, Chevallier JM.• Assistance Publique-Hôpitaux de Paris,
University Paris 5, Paris, France.• Obes Surg. 2013 May;23(5):676-86.
Sleeve LeakSleeve gastrectomy severe complications
• Twenty-two consecutive patients were referred between January 2004 and February 2012 with postoperative gastric leak or stenosis after LSG.
• An endoscopic stent was tried in nine patients but failed in 84.6 % of cases within 20 days (1-161). Seven patients (32 %) necessitated total gastrectomy within 217 days (0-1,915 days) for conservative treatment failure.
Sleeve LeakSleeve gastrectomy severe complications
• Twenty-two consecutive patients were referred between January 2004 and February 2012 with postoperative gastric leak or stenosis after LSG.
• Procedures under general anesthesia were required in 41 % of cases, organ failure was found in 55 % of cases, and central venous device infection in 40 %.
• Mortality rate was 4.5 % (n = 1). Patients with unfavorable evolution of LSG complications (death or additional gastrectomy) had more previous bariatric procedure (82 % vs. 18 %, p = 0.003). Median time to cure was 310 days (9-546 days).
Sleeve LeakSleeve gastrectomy severe complications
• CONCLUSIONS:
• LSG exposes severe complications occurring in patients with benign condition.
• Endoscopic stents entail high failure rate. • Total gastrectomy is required in one third of
the cases.

First Prevent Leaks!!
Error in Thinking of Complications in Surgery
Often Said:
If you are not having complications;
You are not doing surgery
Implying
Complications are Inevitable & little can be done to prevent them
They are expected
Safety & Bariatric Surgery Fear Complacency
• When surgeons Don’t rigorously adhere to
• Rules/Checklist in managing patients, their team & themselves
Safety & Bariatric Surgery Complacency
• Error: Neglect careful attention
• pre, Intra & post-op management guidelines
• (e.g. Leak Prevention Rules)
Safety & Bariatric Surgery Fear Complacency
• Even worse, • Some surgeons choose to Some surgeons choose to
operate knowing of operate knowing of major problems with major problems with their patient or their team their patient or their team
• (Misunderstand Seriousness of Complications)
Examples of ComplacencyComplacencySleeve Gastrectomy Leak
• “Sleeve Gastrectomy & Risk of Leak: Systematic Analysis of 4,888 Patients”
• “Risk of leak is low at 2.4%"

“Risk of leak is low at 2.4%"

“Risk of Airplane Crashes are Low at only 2.4%"

Leak Prevention
Leak Location:
EG Junction (Think Sleeve)
Prevention: Simple:
AVIOD EG Junction!
Dr Rutledge:Who am I to Criticize or Comment
on the Sleeve
In performing over 6,000 Mini-Gastric Bypasses
I have performed more than 6,000 Sleeves
Every MGB includes both a Sleeve and a bypass
My Opinion:Learning from Sleeve Leak Experience
"Division of the posterior fundic vessels is also performed."
(NO NO NO)
“The angle of His is then dissected free from the left crus of the diaphragm.”
(NO NO NO)
"Careful attention on dissection must be taken due to the risk of splenic or esophageal injury"
(NO NO NO)
Prevention: Simple:
AVIOD the EG Junction!
Sleeve Experts Counsel Dissection of the EG Junction
Garth Davis Being in a tertiary referral center for Bariatric surgery I have to tell you that avoiding the GE junction is wrong.
If you leave a fundic "dog ear" it will dilate under the ensuing high pressure and lead to long term weight regain.
I have also had patients referred with the dog ear portion herniating into the hiatus.
Sleeve Experts Counsel Dissection of the EG Junction
Counter argument from Garth Davis:
"Being in a tertiary referral center for Bariatric surgery
"I have to tell you that avoiding the GE junction is wrong.
"As was discussed ample times at the ASMBS meeting,
"you need very good dissection of this area.
Sleeve Experts Counsel Dissection of the EG Junction
Garth Davis Being in a tertiary referral center for Bariatric surgery I have to tell you that avoiding the GE junction is wrong.
"Finally, you will miss hiatal hernia if this are is not dissected.
Proper dissection allows division on cardia without encroaching on esophagus so that no dog ear is present.
Leaks don't happen from dissection in this area. (??)
They happen from stapling onto esophagus or attempting to oversew the staple line." (??)
Learning from Sleeve Leak Experience
In 75-95% the leak location near the
gastro-esophageal junction
Prevention: Simple:
FEAR the EG Junction!
Fundamentals of Gastro-Intestinal Healing
Meticulous HemostasisSLOW Staple Gun Firing Avoid damage to staple
lineDo Not Touch the Staple
LineGentle & precise
handling of tissues
Fundamentals of Gastro-Intestinal Anastomosis Healing
Approximately 3-mm gap between two sutures
Care not to apply excessive tension to prevent cut-through of seromuscular layer
It is necessary to include submucosa carefully because it is the strongest layer of the bowel wall and gives strength to anastomosis.
Handle tissue gently & precisely
“approximate, do not strangulate” to avoid ischemia of the bowel wall at the anastomosis.
For stapled anastomoses, use the correct staple height for the tissue thickness.
Too short & ischemia; Too long, & bleeding or leakThe common staple height for the small bowel
& colon is 3.5 blue, 3.5 mm For the thicker stomach, green, 4.8 mm
Meta-analysis of randomized controlled trials single- vs two- layer intestinal anastomosis
Six trials were analyzed, comprising 670 participants (single-layer group, n = 299; two-layer group, n = 371).
Data on leaks were available from all included studies.
Combined risk ratio 0.91 (95% CI = 0.49 to 1.69), & indicated no significant difference.

Omentum in esophagogastric anastomosis for prevention of anastomotic leak
•Leak in 3 pts with omentum wrapped around the anastomosis patients (3.1%) •14 (14.4%) patients leaked without using the omental patch•Ann Thorac Surg. 2006 Nov;82(5):1857-62.

Omental reinforcement for intraoperative RNY leak repair

Prevent Bleeding:“Go Slow
to Go Fast”
Case Mantra:“No Bleeding”“Easy Case”
How to Stop Bleeding: Direct Pressure - First Aid
Use the Stapler to Compress the
staple line wound
How to Stop Bleeding
Direct Pressure First Aid
Stapler Use
WarningsEnsure to select a stapler with the appropriate staple size for the
tissue thickness. Overly thick or thin tissue may result in unacceptable staple formation.
Do not attempt to remove the shipping wedge until the stapler is loaded into the instrument.
Do not squeeze the handle while pulling back the black retraction knobs.
Do not attempt to override the safety interlock; to do so will render the stapler nonoperational.
Failure to completely fire the stapler will result in an incomplete cut and incomplete staple formation, and may until in poor hemostasis.
Do Not Be ConfusedThere are Two Kinds of Leaks
1. Easy Leaks2. Terrible Disasters
How to tell the difference:Easy = 24 -48 hours
Terrible Disasters = All others

in Treating Leaks
Sleeve Leaks
• Early Diagnosis and Treatment
• Ideally re-explore 24-48 hours
• Late Leak
• Stable vs Infected/Septic
• Stable NPO, NG Across the Leak, GI or IV Feeding, ABx, + Drainage
Sleeve Leaks
• Late Leak
• Infected/Septic
• NPO, NG Across the Leak, GI or IV Feeding, ABx, +Drainage
• Consider re-exploration
Sleeve Leaks
• Debride Necrotic Tissue.
• Drain abscess(s)
• Consider:
• Isolated Roux limb as a serosal patch to cover EG junction defect or as a side to side Thal patch
• Enteral Feeding Tube Below Leak
Sleeve Leaks
• The serosal side of jejunum (Thal patch), Bring the Roux limb up to the injured portion of the EG Junction
• A Roux-Y limb of jejunum, with its independent blood supply and normal healthy tissue may help control the leak by bringing in Healthy tissue to the EG Junction area
Use of a Roux limb to correct esophagogastric junction fistulas after sleeve gastrectomy
• Laparoscopic sleeve gastrectomy (LSG) can be complicated, in the early postoperative course, by an esophagogastric junction (EGJ) leak with very serious consequences.
• A 48-year-old woman developed an EGJ leak 3 days after LSG surgery and was treated with conservative measures.
• Finally, 6 weeks after the original surgery, a Roux limb was brought to the EGJ and anastomosed side-to-end to the fistula.
• At the beginning, the Roux limb was the only functioning outlet and finally, 2 months later, both pathways (the gastric sleeve and the Roux-en-Y) are patent at 3 months after surgery.
• The Roux limb resolved a dangerous EGJ leak after a LSG.• Obes Surg. 2007 Oct;17(10):1408-10. Baltasar A, Bou R, The Surgical Service, Virgen de

Sleeve Leaks
• Acute conversion of Leaking Sleeve to MGB is not advised
• The theoretical advantage decreasing the back pressure of the pylorus is not necessary when the esophagus, stomach pouch and gut are appropriately drained
