Robotic Versus Laparoscopic Anatomic Liver Resection: Comparison of Perioperative Outcomes—A Systematic Review and Meta‐Analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Minimally invasive anatomic liver resection (AR) including major hepatectomy and liver parenchyma‐sparing AR is technically complex and demanding. This systematic review with meta‐analysis including 15 studies comparing 2042 robotic AR and 2129 laparoscopic AR patients demonstrated largely comparable perioperative outcomes and partly better outcomes ...

Short‐Term Outcomes of Robot‐Assisted Versus Laparoscopic Colectomy for Colon Cancer: A Propensity Score‐Matched Analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study compared short‐term outcomes of robot‐assisted versus laparoscopic colectomy for colon cancer using 1:1 propensity score matching. Among 218 matched pairs, robot‐assisted colectomy was associated with reduced blood loss, fewer conversions to open surgery, lower overall complication rates, and shorter hospital stays, despite longer operative ...

Management Strategies for Disappearing Colorectal Liver Metastases After Systemic Chemotherapy: Long‐Term Outcomes and Preoperative Prediction of ‘True Complete Response’

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Determining whether to resect disappearing liver metastases (DLMs) after chemotherapy for colorectal liver metastases (CRLMs) remains challenging. Methods Patients who underwent hepatectomy after systemic chemotherapy for initially unresectable CRLMs were reviewed. True complete response (CR) was defined as either resected DLMs with

Simulation evaluation of a low-altitude helicopter flight guidance system adapted for a helmet-mounted display [PDF]

open access: yes
A computer aiding concept for low-altitude helicopter flight was developed and evaluated in a real-time piloted simulation. The concept included an optimal control trajectory-generation algorithm based upon dynamic programming and a helmet-mounted ...

Bearings only target tracking - maneuvering target

open access: yes, 1984
The estimation of the position and velocity of a target moving in a two- dimensional frame is studied in this paper. The estimator is a Kalman filter which processes noisy bearings of the target gathered by the tracker. The case of maneuvering targets is examined and a solution using a variable value of the system's noise covariance matrix is ...

Efficacy and Safety of a Simple Auxiliary Liver Suspension Device in Complex Laparoscopic Hepatectomy: A Multicenter Randomized Clinical Trial

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Purpose To evaluate the efficacy and safety of a novel auxiliary liver suspension device in complex laparoscopic hepatectomy. Methods A total of 253 patients with hepatocellular carcinoma (HCC) undergoing complex laparoscopic hepatectomy at the Third Affiliated Hospital of Naval Medical University, Sichuan Provincial People's Hospital, and ...
