Pathway Overview
11 steps
Algorithm Steps
11 total
01Start 02Decision Timing of Complication
- Early (<30 days)
- Late (>30 days)
03Decision Early (<30 days)
- Leak (most feared)
- Bleeding
- Obstruction/stricture
- VTE/PE
04Action Leak Workup
CT with oral contrast
- Tachycardia = leak until proven otherwise
- Low threshold for OR if unstable
05Action Leak Management
Drain, stent, or washout
- Contained/stable: NPO, drain, stent/EVT
- Unstable: OR washout, drainage
06End Resolution & Follow-up
Bariatric center follow-up, nutritional monitoring
07Action Bleeding Management
Intraluminal vs extraluminal
- Intraluminal: EGD, usually self-limited
- Extraluminal: CT, may need OR/IR
- Path rejoins step 06Shared downstream outcome
08Action Stricture
EGD with balloon dilation
- 15-18mm target
- Multiple dilations may be needed
- Path rejoins step 06Shared downstream outcome
09Decision Late (>30 days)
- Internal hernia
- Marginal ulcer
- Stricture
- GERD (sleeve)
10Action Internal Hernia
Petersen's, JJ, mesocolic
- CT: mesenteric swirl sign
- May be CT-negative - clinical suspicion key
- Diagnostic laparoscopy if suspicious
- Path rejoins step 06Shared downstream outcome
11Action Marginal Ulcer
EGD, high-dose PPI
- Stop NSAIDs, smoking cessation
- H. pylori treatment if +
- Revision if refractory
- Path rejoins step 06Shared downstream outcome
- Path rejoins step 08Shared downstream outcome

Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Tachycardia is the most reliable early sign of leak
- CT can be falsely negative for internal hernia
- Multidisciplinary bariatric center care recommended
