Interventions/Control_1

Between November 2001 and June 2013, laparoscopic radical cholecystectomy was conducted to the patients who were preoperatively diagnosed with T1b/T2 gallbladder carcinoma, or the patients diagnosed with ocult T1b/T2 gallbladder carcinoma by postoperative pathological examination after laparoscopic cholecystectomy. End points are tumor recurrence and the survival period.

Abstract
Background Laparoscopic surgery has been widely
employed in the field of digestive surgery, since the minimally
invasive procedure provides a significant benefit to patients.
However, laparoscopic curative surgery for gallbladder cancer has been rarely described. The aim of this study was to
evaluate the effectiveness and validity of laparoscopic radical
cholecystectomy with lymph node dissection (Lap-RC) to
treat with T1b/T2 gallbladder carcinoma.
Methods A total of 11 patients underwent Lap-RC for
gallbladder carcinoma from November 2001 until June
2013. While 4 patients were preoperatively diagnosed with
T1b/T2 gallbladder carcinoma, 7 patients were diagnosed
with incidental T1b/T2 gallbladder carcinoma by postoperative pathological examination after laparoscopic cholecystectomy. Common bile duct resection and biliary tract
reconstruction were performed in 2 cases. End points in
this clinical study were tumor recurrence and survival of
patients.
Results Mean operative time was 196 min, and average
hospital stay after surgery was 6.4 days, excluding 2 cases
with biliary tract reconstruction. One patient died of
recurrence of cancer 89 months after surgery, and another
patient died of other reason with local recurrence
39 months after the operation. The other 9 patients were all
alive without recurrence at this writing. The 5-year survival
rate was 100 % for T1b patients and 83.3 % for T2. These
results indicate that almost equivalent outcomes compared
with open surgery in terms of curability were achieved.
Conclusions We conclude that pure laparoscopic radical
cholecystectomy with lymph node dissection is safe and
beneficial for the patients with T1b/T2 gallbladder carcinoma.
