ABSTRACT
Objective:
To study the feasibility,
safety and
technique for laparoscopic anatomical
liver resection of segment 8.
Methods:
The clinical data of 9
patients who underwent laparoscopic anatomical
liver resection of segment 8 from January 2015 to December 2019 at Hunan Provincial People's
Hospital were retrospectively analyzed. There were 6
males and 3
females, with age ranging from 29 to 67 years (average 53.6 years). The operation
time, intraoperative
blood loss , postoperative
hospital stay,
postoperative complications, and long-term
survival and
recurrence rates on follow-up were analysed.
Results:
Laparoscopic anatomical
liver resection of segment 8 was successfully carried out in these
patients. The mean
operative time was 188.9 min(range 140-240 min). The mean estimated intraoperative
blood loss was 117.8 ml (range 20-300 ml). The postoperative
hospital stay was 6.9 days (range 3-12 days). One
patient developed
pleural effusion after operation and responded to
conservative treatment. Another
patients developed
ascites with delayed extubation. The
patient was successfully treated with
conservative treatment. No
patients developed
complications above Clavien Dindo Ⅲa. There were no perioperative deaths. The postoperative pathological results showed
hepatocellular adenoma ( n=2),
hepatocellular carcinoma ( n=4),
cholangiocarcinoma ( n=1), and metastatic
liver cancer ( n=2). On follow-up for 12-58 months (median 22 months) one
patient with
hepatocellular carcinoma developed
recurrence at 18 months after operation and was treated with
microwave ablation. The other
patients were well on follow-up.
Conclusions:
With adequate preoperative evaluation, reasonable case selection, rigorous surgical
planning, and skilled laparoscopic
techniques, laparoscopic anatomical
liver resection of segment 8 was safe and feasible, and the short-term
efficacy was good in this study.
