Open Cholecystectomy: Mastering the 'Lost Art' in Emergency General Surgery

The Necessity of Open Cholecystectomy

• 💡 Cholecystectomy is one of the most performed operations in the US, with 6-7% of complications and 3-4 per 1000 operations resulting in bile duct injury, even for experienced surgeons.
• ⚠️ Severe gallbladder inflammation can be like a "grenade with a pin," and complications like bile duct injuries can be career-altering.
• 🎯 Risk factors for difficult cholecystectomies include male sex, elderly patients, high ASA scores, multiple prior abdominal surgeries, diabetes, prior sphincterotomy, and delayed surgery.

Safe Cholecystectomy Principles

• 🔑 The SAGES Safe Cholecystectomy Program outlines six strategies to minimize bile duct injuries.
• 1️⃣ Use the critical view of safety to identify the cystic duct and artery.
• 2️⃣ Understand potential for aberrant anatomy and review pre-op imaging.
• 3️⃣ Make liberal use of cholangiography or other methods to image the biliary tree.
• 4️⃣ Consider an intraoperative pause before clipping or cutting ductal structures.
• 5️⃣ Recognize and halt dissection when approaching a zone of significant risk.
• 6️⃣ Get help from another surgeon when dissection is difficult.

Bailout Strategies: Subtotal vs. Open

• ❓ When dissection is too dangerous, bailout strategies like subtotal cholecystectomy (fenestrating or reconstituting) are considered.
• ⚠️ While subtotal techniques may show fewer bile duct injuries in some studies, open cholecystectomy generally outperforms them in terms of bile leaks, need for ERCP, reoperations, and drainage.
• 🧠 The fenestrated technique has a 35% bile leak rate and requires ERCP in 44% of cases, while reconstituting techniques can lead to recurrent gallstone disease.

Mastering Open Cholecystectomy Technique

• 🎯 An open cholecystectomy is initiated with a right subcostal incision, two finger-breadths below the costal margin.
• 🛠️ Proper retraction is crucial, using a combination of retractors to provide good visualization of the operative field.
• 🔥 High-power cautery (e.g., 60/60) is recommended for dissecting through inflammatory rind and achieving hemostasis.
• 💡 Developing the plane between the gallbladder wall and the liver bed is key, using blunt dissection with fingers or instruments, and being willing to mobilize the dissection.
• 🔍 At the infundibulum, tension and counter-tension are vital, with multiple clamps on the gallbladder to aid dissection.
• ⚠️ Be aware of the anterior wall of the common bile duct when inflammation is severe at the porta hepatis.

Intraoperative Judgment and Closure

• ❓ When identifying structures at the infundibulum, instruments like right-angle clamps and Babcock forceps are used for traction and dissection.
• 🩸 Expect a bloody field, but trust that controlling the cystic duct and artery will lead to hemostasis.
• 💡 If the cystic duct is obliterated or difficult to dissect, consider opening the gallbladder from the inside to aid visualization or palpation.
• 🩺 Adjuncts like cholangiography or ICG can help delineate anatomy before committing to cutting structures.
• 🩹 Drains are typically not needed if the cystic duct is secured, but may be considered if there's a large abscess cavity or if the cystic duct is obliterated and cannot be confidently controlled.
• ✅ Ligation of the cystic duct can be done with silk, PDS, or clips, depending on tissue quality and depth of dissection. When in doubt, leaving a drain is a safer option than causing further injury.
• 🪡 Fascia should be closed in two layers using a slowly absorbing stitch, ensuring a good outcome for the patient.
