4

Difficult Cholecystectomy• Severe inflammation • Fibrosis• Aberrant anatomy

Calot’s Triangle

Complications• CBD injury• Vascular injury• Hollow viscous injury

5

Conversion to Open total chole• Conversion rates vary btw 1.5-10%

Tang B, Cuschieri A. Conversions during laparoscopic cholecystectomy: risk factors and effects on patient outcome. J Gastrointest Surg. 2006. (10):1081-1091.

6

Subtotal Cholecystectomy• Introduced by

Bornman et al. 1985 to reduce CBD injury

• Involves excision of anterior wall and closure of cystic duct from within GB

Objective• To compare the outcomes between

subtotal cholecystectomy vs. open total cholecystectomy in patients with complicated cholecystitis

• Retrospective analysis• 1/2008 - 12/2012 (5 years)

• ICD-9 codes for Open Cholecystectomy and Subtotal Cholecystectomy

Methods

8

• Study groups• Subtotal Cholecystectomy (63)• Lap converted to OTC (151)

Methods

9

• Chart review• Preoperative labs • Imaging• Operative and discharge notes

Methods

10

• Outcomes• HLOS• ICU LOS• Intraoperative complications

• CBD injury• Vascular injury• Hollow viscous injury• Bile Leak• Retained Gallstones• Wound Infections• Subhepatic Abscesses

Conclusions• SC is a viable alternative• Significant decrease severe

complications• CBD injury + vascular injury + hollow

viscous• Further study is needed

• Prospective design using predictive scale to control for difficulty of cholecystectomy
