Cholecystectomy class
- 1. OPEN CHOLECYSTECTOMY Dr Tridip Dutta Baruah Asst Prof, General Surgery
- 2. Locations of the Liver and Gallbladder (Modified from Herlihy B and Maebius NK: The human body in health and illness, ed 2, Philadelphia, 2003, Saunders.) Fuller
- 4. Indications Indications for cholecystectomy, either open or laparoscopic, are following: • Cholecystitis • Cholelithiasis • Choledocholithiasis • Gallbladder calcification • Biliary colic and Biliary pancreatitis • Other indications include biliary dyskinesia, • gallbladder cancer
- 5. contraindications Absolute contraindications are few. • Severe physiologic derangement or cardiopulmonary disease that prohibits general anesthesia. • In cases of terminal illness, temporizing procedures such as percutaneous transhepatic cholangiography or percutaneous cholecystostomy should be considered in lieu of cholecystectomy.
- 6. Anesthesia • Most open cholecystectomies are performed with general anesthesia. • Less common alternatives include regional (epidural or spinal) and, rarely, local anesthesia
- 7. Positioning • Patients are positioned supine with arms extended. Placing a folded blanket or bump underneath the patient's right back or • inverting the table may be beneficial
- 8. Technique In general, open cholecystectomy can be performed by either of two different approaches: • Retrograde • Anterograde
- 9. Preparation • Patient positioning • Place a Foley catheter • Administer preoperative antibiotics within 60 minutes of skin incision. • The surgeon stands on the patient's left with the assistant opposite side.
- 10. Incision • A right subcostal (Kocher) incision is the most often used incision. • Alternatively, an upper midline incision can be used when other concomitant operations are planned and a wider exposure is needed. • A right paramedian incision is another option.
- 11. subcostal incision • Start the subcostal incision approximately 1 cm to the left of the linea alba, about 2 fingerbreadths below the costal margin (approximately 4 cm). Extend the incision laterally for 10 cm. • Incise the anterior rectus sheath along the length of the incision, and divide the rectus and lateral muscle (external oblique, internal oblique, and transversus abdominis) using electrocautery. • Then incise the posterior rectus sheath and peritoneum and enter the abdomen.
- 12. Inspection • To the extent possible, perform a thorough manual and visual inspection to evaluate for concomitant pathology or anatomical abnormalities. • Place a retractors after packing as needed for adequate exposure. • Palpate and inspect the liver and the gallbladder for stones or masses.
- 13. Cholecystectomy The gallbladder is retracted, allowing dissection of the cystic duct and artery (Colorized from Moody FG: Atlas of ambulatory surgery, St Louis, 1999, Mosby.)
- 14. Cholecystectomy (Colorized from Moody FG: Atlas of ambulatory surgery, St Louis, 1999, Mosby.) The cystic artery and duct are clipped and cut
- 15. Dissection • Grasp the dome of the gallbladder with a Kelly clamp and elevate it superiorly. • Adhesions to the undersurface of the gallbladder from the transverse colon or duodenum are typically encountered; these can be lysed with sharp dissection or judicious use of electrocautery. • Dissection of the gallbladder can be performed in two ways Fundus first or Duct first. • Traditionally, dissection in open cholecystectomy is performed by Duct first method.
- 16. Duct first method • In the anterograde approach, attention is initially directed to the porta hepatis. Grasp the fundus of the gallbladder and elevate it superiorly while the neck of the gallbladder is mobilized away from the liver laterally to expose the triangle of Calot. • Dissect the cystic artery and cystic duct with careful attention to the potential for anatomical variations. • Dissect the cystic duct and cystic artery completely till they are clearly identified entering directly into the gallbladder (the socalled critical view popularized by Strasberg).
- 17. Cholecystectomy (Open) Cystic duct is tied close to the gallbladder with a 2-0 silk (From Economou SG and Economou TS: Atlas of surgical technique, ed 2, Philadelphia, 1996, Saunders.)
- 18. Division of Duct and Artery • Before division of the cystic duct, "milk" the duct from proximal to distal to deliver stones that reside in the cystic duct into the gallbladder lumen. • When the cystic duct and artery are correctly identified and completely dissected, they are ligated. • Nonabsorbable sutures are acceptable for use on the cystic duct stump; however, they are not recommended. • Absorbable sutures, such as polyglactin 910 or polydioxanone are used for ligation of the cystic duct. Metallic (titanium) clips or locking (Weck) clips can be used. If the cystic duct is large and inflamed, mechanical staplers may be used. • The cystic artery can be ligated with ties (absorbable or nonabsorbable), suture ligature, or clips.
- 19. • Following divisions of the cystic artery and duct, dissect the gallbladder away from the liver bed. The dissection plane is typically avascular, with only small cholecystic veins that need to be divided. • If significant bleeding occurs, the dissection has likely been too deep entering the liver parenchyma.
- 20. Complications • Bleeding and infection- Inherent to any surgical procedure. • Biliary complications- Complications related to the biliary system include bile leaks and common. bile duct injuries, which can result in Biliary strictures
