Role of laparoscopic staging in the resectability of gallbladder cancer / 中华普通外科杂志

ABSTRACT

Objective To evaluate the role of laparoscopic staging for the resectability of gallbladder cancer. Methods From Jan 2007 to Mar 2010,60 gallbladder cancer patients without of metastatic disease or main hepatic portal vessel invasion as assessed by preoperative imaging underwent staging laparoscopy for tumor resectability evaluation. Peritoneal and liver surface metastases were looked for and assessment of local spread was done if possible. Assessment was based on visual impression and biopsies were obtained routinely. T test and x2 test were used. Results At laparoscopy, 27 (45%) patients were found with disseminated disease on peritoneal cavity or the surface of liver, hence, senseless open surgery was avoided. The other 33 patients were converted to open laparotomy, among those 1 patient was found with disseminated metastasis in the liver and 12 patients with the invasion of main hepatic portal vessel,pancreatic head, duodenum did not undergo any further surgery. Finally 7 patients received surgical bypass procedure and 13 patients underwent radical resection. During the same period, 192 clinically diagnosed gallbladder cancer patients undergoing open laparotomy without laparoscopic pre-assessment served as control. Among those in control group 79 patients received radical or palliative resection. The resectability rate was significantly different between the two groups ( P ＜ 0. 05). Conclusion Staging laparoscopy in patients with gallbladder cancer is helpful in detecting liver and peritoneal metastases overlooked by preoperative imaging, avoiding unnecessary open explorations.
