Introduction: Multidimensional comparison between open, laparoscopy, and robotic surgery in the management of right-sided colon cancer are lacking. The aim of this study was to compare the early perioperative results and oncologic outcomes among the 3 different methods.
Patients And Methods: Between June 2007 and 2011, a total of 96 patients who underwent right hemicolectomy in a single institution were classified into the open surgery (OS; n=33), the laparoscopy surgery (LS; n=43), and the robot surgery (RS; n=20) groups. Perioperative and oncologic outcomes were compared among the 3 groups.
Results: Patient demographics were comparable. Operation time was significantly longer in the RS and LS than the OS (P<0.001). There was 1 OS conversion in LS. There was no difference of total retrieved lymph node numbers among the 3 groups. Postoperative recovery was faster and hospital stay was shorter in RS than OS. However, there was no difference between LS and RS. After the median 40 months' follow-up, 5-year disease-free survival was similar among the OS, LS, and RS (87.7%, 84%, and 89.5%, respectively). Total charge and total patient charge were significantly higher in RS than the others.
Conclusions: Our comparative study demonstrates that the RS have better short-term outcomes in reducing hospital stay compared with the OS, but similar to the LS. Although the oncologic outcomes are similar, the benefit of RS in right hemicolectomy is unclear considering a high cost of RS.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.

With the rapid advance of technology, human interactions with virtual avatars in simulated social environments are becoming increasingly common. The aim of the current study was to examine users' perception of social traits and emotions of "neutral," expressionless avatars using an open-source collection. These avatars represented different ethnicities, genders, and occupations via visual features including skin tone, facial structure, and apparel.

Importance: It remains unknown whether outcomes of the Placement of Aortic Transcatheter Valves 3 (PARTNER 3) and Evolut Low Risk trials are comparable with surgical outcomes in nontrial settings, considering the added risk of concomitant cardiac operations.
Objective: To compare 30-day mortality and stroke incidences of patients in the surgical aortic valve replacement (SAVR) arm of low-risk trials with those of similar patients in the US Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD).
Design, Setting, And Participants: A cross-sectional sampling study was conducted of adults in the STS ACSD with severe aortic stenosis at low surgical risk for AVR who underwent SAVR during the years low-risk AVR trials (PARTNER 3 and Evolut Low Risk) were enrolling (calendar years 2016-2018).
Background: Intramedullary screw (IMS) fixation for metacarpal fractures is a relatively new fixation technique in comparison to plate and screw constructs. Our hypothesis evaluated whether IMS fixation for metacarpal fractures results in lower overall health care-associated costs in comparison to open reduction and internal fixation (ORIF).
Methods: A retrospective review of patients undergoing IMS fixation for metacarpal fractures at a single center during 2018 to 2022 was conducted.
