Laparoscopic Cholecystectomy(LC) Indication: Symptomatic gallstones l Other biliary tract disease l Difficult technical challenges Acute cholecystitis l Obesity l Previous intra-abdominal surgery l Pregnancy l
LC-surgical technique Reverse Trendelenburg position Intraperitoneal CO 2 insufflation
LC-surgical technique
Benefit of LC Shorter hospital stays More rapid return to normal activities Small, limited incisions Less pain Less postoperative ileus
LC vs OC Treatment of Acute Cholecystitis Conversion rate: 15% l Operationg time: 88 vs 77 mins l Complication: 14% vs 23% l Hospital stay: 3. 3 vs 8. 1 days l Laparoscopic cholecystectomy vs Open cholecystectomy in the treatment of acute cholecystitis(ARCH SURG volume 133)
Anesthetic management Anesthetic technique l Regional anesthesia l l Thoracic epidural anesthesia(T 2) Advantage: l l Awake Protective airway reflex Shorter recovery Disadvantage: l l l Diaphragm irritation Significant nausea and vomiting Referred pain : neck and shoulder
Anesthetic management Anesthetic technique General anesthesia l Cuffed endotracheal tube placement l Controlled ventilation l Urinary catheter and nasogastric tube l
Anesthetic management Anesthetic agents Oxygen l Nitrous oxide l Volatile anesthetic agent l Relaxants l Opioids: Oddi sphincter spasm l
Anesthetic management Use of nitrous oxide l Controversial Bowel distention l Postoperative nausea l
Anesthetic management Monitoring l PETco 2 Increased minute ventilation by 12~16% l Paco 2 must less than 41 mm. Hg l l Invasive hemodynamic monitoring ASA class III~IV l Especially at p’t with cardiopulmonary disease l
Anesthetic management Post operative pain relief Wound infiltration with local anesthesia and NSAID - for peripheral pain l Opioids - for central pain l Ondansetron – for nausea and vomiting l
