Background: Conversion rate to open surgery is higher for patients with acute cholecystitis than in those without acute cholecystitis. We attempted to develop a laparoscopic subtotal cholecystectomy to decrease this conversion rate.
Methods: From 2000 to 2005, laparoscopic cholecystectomy for acute cholecystitis was performed in 60 patients (22 women, 38 men). Patients were divided into two groups: group A (2000 to 2002, n = 22) and group B (2003 to 2005, n = 38). When significant difficulty was encountered dissecting the gallbladder from its bed, we incised the gallbladder wall leaving the posterior wall and cauterizing the remnant mucosa (subtotal cholecystectomy, SC-1). When dissection of the gall bladder neck and triangle of Calot was difficult, the neck of the gallbladder was sutured despite clipping (SC-2).
Results: Mean duration from onset of symptoms to operation was 55.3 +/- 52.0 days. SC-1 was performed in 8 patients in group A and 18 patients in group B. SC-2 was performed in three patients in Group B. Conversion rate was 18.1% (4/22) in group A and 0% (0/38) in group B, compared to 0.4% (1/221) for patients without acute cholecystitis. No complications were associated with ablated gallbladder mucosa.
Conclusion: Laparoscopic subtotal cholecystectomy offers safe and effective treatment for acute cholecystitis. The conversion rate in group B is decreased by avoiding hazardous dissection of the cystic duct.
