Indications / Contraindications
Indications
- Acute calculous cholecystitis in high-risk surgical candidate (ASA 3-4)
- Acute acalculous cholecystitis (AAC) — critically ill ICU patients; mortality >50% without treatment
- Bridge to cholecystectomy — stabilize patient, then plan elective surgery
- Gallbladder perforation with bile leak
- Malignant gallbladder obstruction
- Portal for biliary interventions — transcholecystic CBD access when ERCP and PTBD not feasible
Contraindications
- Absolute: None in true emergencies
- Relative: Uncorrectable coagulopathy (SIR Cat 2-3 — correct when possible)
- Relative: Massive ascites, especially transperitoneal approach
- Relative: Non-distended gallbladder (no target for access)
- Relative: Hepatic cirrhosis with portal hypertension — favor transperitoneal to avoid hepatic veins
Patient Populations
- ICU patients: Acalculous cholecystitis common in the critically ill (trauma, post-op, TPN-dependent, burns)
- Elderly with multiple comorbidities: Cannot safely undergo general anesthesia or laparoscopic cholecystectomy
- Patients on anticoagulation: High bleeding risk with surgery; cholecystostomy is lower risk

Pre-Procedure Checklist
Imaging review. US: wall thickening (>3.5 mm), pericholecystic fluid, sonographic Murphy's sign, stones or sludge. CT: for anatomy, ascites, and bowel interposition on planned access route. HIDA if diagnosis uncertain — no GB visualization at 60 min after morphine augmentation = acalculous cholecystitis (99% sensitivity).
Labs (SIR Category 2-3). CBC (leukocytosis), LFTs, BMP, coagulation panel. INR <1.5, platelets >50K for transhepatic approach. Transperitoneal approach slightly lower risk — no hepatic parenchyma traversal. Bilirubin elevation suggests CBD involvement — may need PTBD in addition.
Antibiotics. Piperacillin-tazobactam 3.375g IV prior to procedure. Continue 24-48h post-procedure. Covers the broad enteric spectrum (gram-negatives, anaerobes) expected in biliary infections.
Approach planning. Transhepatic (preferred): more stable catheter, less bile leak risk, suitable when bowel interposition or ascites preclude direct access. Transperitoneal: preferred with coagulopathy, cirrhosis, or hepatomegaly — no hepatic parenchyma traversal.
Consent. Discuss: bile peritonitis (~1%), hemorrhage (<1%), vasovagal reaction during procedure, catheter dislodgement, need for surgery if no clinical improvement (~10% of patients). Emphasize that drain must NOT be removed early.

Relevant Anatomy
Gallbladder and Access Principles
- Gallbladder lies in fossa on inferior surface of right liver (segments IVb and V). Fundus is the most anterior and inferior portion.
- Access should target the GB fundus or body; approach along the long axis when possible to maximize catheter stability and pigtail formation
- Fundus is furthest from hilar structures — safest access point, minimizing risk to CBD, hepatic artery, and portal vein
- Neck connects to cystic duct → CBD. Do not puncture the cystic duct or CBD.
Transhepatic Approach (Preferred)
- Needle traverses liver parenchyma before entering GB
- Liver parenchyma acts as a seal around the catheter — bile peritonitis risk dramatically reduced if catheter dislodges
- More stable catheter position; preferred for GB body/neck access
- Use for: bowel interposition, large ascites, most routine cases
- Avoid if: severe coagulopathy, significant hepatomegaly, cirrhosis with portal hypertension
Transperitoneal Approach
- Direct puncture of GB fundus through anterior abdominal wall — no liver traversal
- Higher bile leak risk if catheter dislodges (no hepatic seal)
- Lower hemorrhagic risk — no hepatic parenchymal crossing
- Preferred for: coagulopathy, cirrhosis, hepatomegaly, pregnancy
- Must confirm no bowel interposition on US/CT before proceeding
Danger Structures
- Hepatic flexure of colon: Can interpose between anterior abdominal wall and GB fundus — confirm on US in real-time
- Duodenum: Medial to GB neck — avoid needle trajectory toward duodenum
- Hepatic artery and portal vein (hilum): Avoid central/hilar access; always target fundus/body
- CBD: Avoid puncturing common bile duct — access GB lumen only

Trocar vs. Seldinger Technique
Trocar (preferred in critically ill)
- One-stick technique — combined catheter/cannula/stylet advanced directly into GB
- Faster; no wire exchange needed
- Preferred when GB may collapse before catheter is in — decompresses in same motion
- Use for: distended GB, critically ill, urgent cases
Seldinger
- Needle → aspirate bile confirmation → wire → dilate → catheter
- Allows small-needle confirmation before large catheter placement
- Use for: deep GB, uncertain access, or when confirming bile return before committing
Steps
1
US survey and planning
Identify gallbladder, measure wall thickness, locate fundus and body. Plan transhepatic vs. transperitoneal based on anatomy and patient risk factors. Look for colon or bowel interposition on transperitoneal approach in real-time. Measure depth from skin to GB lumen.
2
Prep and local anesthesia
Sterile prep with ChloraPrep. Sterile drape. Local anesthesia: 1% lidocaine infiltrated from skin to GB capsule (transhepatic) or GB wall (transperitoneal). Do not enter the GB lumen with the anesthesia needle.
3
Access under continuous real-time US guidance
Trocar method (preferred in critically ill): advance 18G trocar needle-catheter system under continuous real-time US directly into GB lumen in a single motion. Aspirate bile to confirm position. OR Seldinger: advance access needle, aspirate bile, advance 0.035" wire, dilate tract, advance catheter.
4
Bile aspiration and culture
Aspirate bile for gram stain and culture — critical diagnostic step. Note appearance: purulent = infected; bloody = hemorrhagic cholecystitis; dark green = concentrated; mucoid = mucocele. Send: aerobic culture, anaerobic culture, gram stain.
5
Catheter placement and pigtail formation
Advance 8 Fr locking pigtail catheter over wire (Seldinger) or confirm trocar catheter position. Release locking mechanism to form pigtail within the GB lumen. Confirm catheter position on US — catheter should be visible within the gallbladder and bile should flow freely.
6
Secure and connect
Suture catheter to skin with 0-silk. Connect to external drainage bag. Record initial output volume, color, and character. Order nursing flush instructions (5-10 mL sterile saline q12h).

Troubleshooting
Problem
Gallbladder collapses during access
Likely cause: GB wall decompresses as needle tip perforates the wall — particularly if GB is tensely distended. Occurs before catheter is fully advanced.
Next step: Trocar technique is preferred precisely to avoid this — catheter and needle advance together so the GB is entered and secured in one motion. If using Seldinger and GB collapses: advance wire quickly before GB decompresses. Consider switching to trocar on next case.
Problem
Difficult access — GB not well distended
Likely cause: GB not adequately distended (partially decompressed, small or contracted GB, stones preventing distension). Small target is technically challenging under US alone.
Next step: CT guidance or cone-beam CT may help in complex anatomy. Ensure patient is fasted (GB distends without stimulation). If still inadequate target, reconsider the diagnosis — a non-distended GB is less likely to be the source of acute cholecystitis.
Problem
No bile return on aspiration
Likely cause: Needle not in GB lumen — may be in liver parenchyma, pericholecystic fluid, or adjacent bowel.
Next step: Confirm on real-time US that needle tip is within the GB lumen. Withdraw and redirect if not clearly intraluminal. Aspirate slowly — very thick bile (pus or inspissated bile) may require gentle suction. If still no return with correct position, viscous contents may require wire-based confirmation of position before proceeding.
Problem
High-output bile from drain (>500 mL/day)
Likely cause: Normal in first 24-48h as a tensely distended GB decompresses. Ongoing high output suggests cystic duct obstruction, continued biliary leak into GB, or CBD fistula.
Next step: Expected early on. Monitor electrolytes if high volume (bile contains bicarbonate, chloride, potassium). If output remains >500 mL/day beyond 72h, consider cholescintigraphy or cholecystocholangiogram to assess cystic duct patency and CBD anatomy.

Complications
Immediate / Periprocedural
- Bile peritonitis (1-4%) — catheter dislodgement or inadequate hepatic seal (transperitoneal approach); most feared complication
- Hemorrhage — usually minor tract hemostasis; significant if hepatic vessel injured (transhepatic approach)
- Vasovagal reaction — monitor during and immediately after; have atropine available
- Procedure-related sepsis — infected bile manipulation; pre-procedure antibiotics essential
Delayed
- Catheter dislodgement — most common delayed complication; patient education critical; do not remove early
- Catheter occlusion — requires flush or exchange; sludge common in cholecystitis
- Failed decompression requiring surgery (~10%) — gangrenous cholecystitis, emphysematous cholecystitis, perforation; surgical consult when no clinical improvement at 48-72h
- Peritoneal access site bleeding — rare, usually self-limited
- Skin site infection — regular dressing changes and site inspection
7
Post-Procedure Care
Clinical Response Assessment
- Clinical response expected within 24-72 hours: fever resolves, WBC trending down, RUQ pain improving
- Output: 50-500 mL/day bile drainage expected; high output in first 24-48h is normal
- If no clinical improvement at 48-72h: CT to reassess for gangrenous cholecystitis, GB perforation, or drain malposition
- Surgical consult if no improvement — approximately 10% of patients will ultimately require cholecystectomy urgently
Long-Term Planning
- Cholescintigraphy (HIDA) at 4-6 weeks if cholecystectomy planned: cystic duct patency determines if laparoscopic approach remains feasible
- Cholecystectomy timing: Elective laparoscopic cholecystectomy 6-8 weeks after acute resolution in fit patients
- For non-surgical candidates: long-term catheter management with scheduled exchanges every 3 months
- Drain removal only after fistula tract maturation (~4 weeks minimum) AND confirmed cystic duct patency AND resolution of cholecystitis

Critical Pearls
✦
Transhepatic approach is preferred — liver parenchyma seals around the catheter, preventing bile peritonitis if the catheter dislodges. Transperitoneal approach loses this protection.
✦
Trocar one-stick technique is faster and preferred in critically ill — the catheter and needle advance together so the GB is entered and secured before it can decompress. Less risk of GB decompression before catheter is in place.
✦
Critically ill patients may not show classic cholecystitis signs — ICU patients with AAC often lack fever, RUQ tenderness, or leukocytosis. Have a low threshold for cholecystostomy when clinical picture fits in an ICU patient with unexplained sepsis.
✦
Do NOT remove drain until fistula track has matured (4 weeks minimum) — if removed too early before track formation, bile will spill into the peritoneum, causing bile peritonitis. Patient education is critical. Document this clearly in discharge instructions.
✦
10-30% of patients fail cholecystostomy and eventually require surgery — counsel patients and families accordingly. Gangrenous cholecystitis, emphysematous cholecystitis, and GB perforation are more likely to fail conservative management.
✦
AAC mortality: Acalculous cholecystitis carries >50% mortality without treatment in critically ill patients. Cholecystostomy is a potentially life-saving intervention in this population — do not delay for marginal lab corrections.

Drain Management + Removal Criteria
| Parameter | Normal / Target | Action / Notes |
|---|---|---|
| Output monitoring | 50-500 mL/day | High output in first 24-48h is expected; if persistently >500 mL, check cystic duct and CBD on cholecystocholangiogram |
| Flushing | 5-10 mL sterile saline q12h | Nursing order required to maintain patency; prevents sludge accumulation in catheter |
| Dressing change | Every 3-5 days or when soiled | Inspect skin entry site for erythema, bile leak, or signs of drain migration |
| Imaging confirmation | Cholecystocholangiogram at 4 weeks | Confirm cystic duct patent before removal; inject dilute contrast through catheter under fluoroscopy |
| Removal criteria (all must be met) | Mature tract (4+ weeks) + clinical resolution + patent cystic duct on imaging | Never remove early; if all three criteria not met, continue drainage and reassess |
| Long-term exchange | Every 3 months if long-term drainage needed | For non-surgical candidates; scheduled IR follow-up with cholangiogram at exchange |
| Signs of dysfunction | — | Returning RUQ pain, fever, WBC rising, decreased output or output cessation — all warrant urgent reassessment |
| Cholecystectomy timing | 6-8 weeks after resolution | For surgical candidates; confirm with surgery team; HIDA prior to surgery if laparoscopic approach planned |
