BACKGROUND Laparoscopic treatment for gallbladder cancer (GBC) has long been contraindicated, but few studies have demonstrated the oncologic outcomes of this treatment. The purpose of this study was to evaluate long-term survival after intended laparoscopic surgery for early-stage GBC based on our 10 years of experience. STUDY DESIGN Between May 2004 and April 2014, eighty-three patients suspected of having early-stage GBC with no evidence of liver invasion were enrolled in the prospective protocol for laparoscopic surgery. Data for 45 of these patients with pathologically proven GBC were analyzed to determine the safety and oncologic outcomes of a laparoscopic approach to GBC. Twenty-six patients whose postoperative follow-up exceeded 5 years were investigated to determine the 5-year actual survival outcomes. RESULTS Extended cholecystectomy, including laparoscopic lymphadenectomy, was performed in 32 patients and simple cholecystectomy in 13 patients. The T stages based on final pathologic results were Tis (n = 2), T1a (n = 10), T1b (n = 8), and T2 (n = 25). After a median follow-up of 60 months after surgery, recurrence was detected in 4 patients as distant metastases. There was no local recurrence around the gallbladder bed or lymphadenectomy. Disease-specific 5-year survival rate of the 45 patients was 94.2%. Disease-specific actual survival rate of 26 patients whose postoperative follow-up period exceeded 5 years was 92.3% at 5 years. CONCLUSIONS The favorable long-term oncologic results shown in this study confirm the oncologic safety of laparoscopic cholecystectomy, including laparoscopic lymphadenectomy in selected patients with GBC.

The prognostic relevance of preoperative diabetes mellitus (DM) on the outcomes of resected pancreatic ductal adenocarcinoma (PDAC) is controversial. Most previous studies evaluated the prognostic role of DM based on a single blood test.

Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

Introduction: Laparoscopic liver resection has become important procedure for malignant liver disease. In this report, we describe the relevant technical maneuvers and perioperative outcomes in laparoscopic anatomic segment 6 liver resection using the Glissonian approach. Patients and Methods: From March 2003 and October 2015, 7 patients who diagnosed hepatocellular carcinoma had undergone laparoscopic anatomic segment 6 liver resection at the single institution. We performed retrospective analysis of the clinical and perioperative outcomes of these patients. Results: All patients were men with mean age of 62.3 years (range, 49 to 73 y). The mean operation time was 352.8 minutes (range, 180 to 435 min) and there was no case of open conversion. The mean estimated blood loss was 521.4 mL (range, 200 to 800 mL) and intraoperative transfusion needed in 1 patient. There was no postoperative morbidity and mortality. The mean postoperative hospital stay was 7.5 days (range, 5 to 12 d). All patients obtained negative resection margins. There was no patient had developed tumor recurrence during a median follow-up period of 43 months (range, 7 to 60.7 mo). Conclusions: Laparoscopic anatomic segment 6 liver resection is a feasible operative procedure, being possible even in patients with limited liver function.
