Background: Robotic surgery is increasingly being used in hepatectomy. Previous studies comparing the robotic and laparoscopic minor hepatectomy have been documented, but comparative studies on robotic and laparoscopic hemihepatectomy (LH) involving a large patient cohort are rare. The objective of this study was to compare perioperative outcomes between robotic and LH.Methods: Data on the demographics, clinicopathologic characteristics, and perioperative outcomes of consecutive patients who underwent robotic or LH in a single center between November 2011 and July 2017 were analyzed.Results: A total of 92 patients underwent robotic and 48 LH. Multiple linear regression analysis showed no significant difference in perioperative outcomes including operative time, postoperative hospital stay, postoperative complications, and mortality between the groups. Compared to the laparoscopic cohort, the robotic cohort had a significantly less estimated blood loss (120.24 mL; 95% confidence interval, 53.72-186.76) and a significantly lower conversation rate (1.09% vs 10.42%; P = .034). Stratified and interaction analyses demonstrated that disease type had an interaction effect on the association between the operative approach and the estimated blood loss.Conclusions: Robotic hemihepatectomy was safe and feasible in selected patients.It had similar perioperative outcomes as LH and was better than LH regarding estimated blood loss and open conversion.

One-stage synchronous laparoscopic resection of liver metastatic CRC is a feasible, effective, and safe modality in specifically indicated patients, both accelerating postoperative recovery and shortening hospitalization time.

Background Radical resection for hilar cholangiocarcinoma is considered one of the most complicated abdominal operations. We report our initial experience with robotic radical resection for hilar cholangiocarcinoma. Methods Between March 2017 and February 2019, the perioperative outcomes of 48 patients were analysed. In addition, there were two techniques for hepaticojejunostomy in the robotic approach. Comparison of the conventional and novel methods for hepaticojejunostomy was also performed to assess the efficacy of the technique. Results The operative duration and intraoperative blood loss volume was 276 minutes and 150 mL, respectively. The overall morbidity was 58.3% and the major morbidity was 10.4%. The overall mortality was 0%. No significant differences in the perioperative outcomes of hepaticojejunostomy were found between the 2 groups. Conclusion Robotic resection is a potential alternative to open surgery for appropriately selected patients with hilar cholangiocarcinoma. Further studies are required to detect the long‐term outcomes of this procedure.

Laparoscopic surgery is a safe procedure for patients with benign insulinomas. The complication rates are comparable with those for laparotomy procedures. Relative to open operations, laparoscopic pancreas operations are associated with a more rapid postoperative recovery.

Laparoscopic pancreatic resection is a feasible and safe procedure for patients with insulinomas. Further studies are required to evaluate the potential application of the hand-assisted approach for tumors located at anatomically unfavorable positions.

Our experience with carefully selected cases meeting specific criteria suggests that laparoscopic hepatic re-resection is a safe, feasible procedure that may offer multiple benefits for treating recurrent hepatocellular carcinoma.

Three-dimensional (3D) cell culture has been reported to increase the therapeutic potentials of mesenchymal stem cells (MSCs). However, the action mechanisms of 3D MSCs vary greatly and are far from being thoroughly investigated. In this study, we aimed to investigate the therapeutic effects of 3D spheroids of human adipose-derived MSCs for hepatic fibrosis. Our results showed that 3D culture enhanced the expression of antifibrotic factors by MSCs, including insulin growth factor 1 (IGF-1), interleukin-6 (IL-6), and hepatocyte growth factor (HGF). In vitro studies indicated conditioned medium of 3D cultured MSCs protected hepatocytes from cell injury and apoptosis more effectively compared with 2D cultured cells. More importantly, when transplanted into model mice with hepatic fibrosis, 3D spheroids of MSCs were more beneficial in ameliorating hepatic fibrosis and improving liver function than 2D cultured cells. Therefore, the 3D culture strategy improved the therapeutic effects of MSCs and might be promising for treatment of hepatic fibrosis.

Single-port laparoscopic LLLS is a technically feasible, effective, safe alternative to multi-port laparoscopy for the treatment of benign liver diseases in cautiously selected patients.
