Purpose:
Laparoscopic cholecystectomy is the gold standard procedure for benign gallbladder disease. However, reducing ports still causes frustration when using various instruments. We investigated early perioperative outcomes of laparoscopic single site + 1 cholecystectomy using ArtiSential instruments (ArtiSential laparoscopic cholecystectomy [ALC], LIVSMED).
Methods:
From July 2022 to December 2022, 116 patients underwent ALC in Severance Hospital and Yongin Severance Hospital. From May 2019 to December 2022, 210 patients underwent robotic single-port cholecystectomy (RSPC). We compared clinical characteristics, perioperative outcomes, and postoperative pain scores between the ALC and RSPC groups.
Results:
Patients in the ALC group were significantly older than those in the RSPC group (51.9 years vs. 43.9 years, P < 0.001), and the ALC group had a larger proportion of male patients (50.9% vs. 24.8%, P < 0.001) and cases of acute cholecystitis with stones (21.6% vs. 0.5%, P < 0.001) than the RSPC group. The groups did not differ in their estimated blood loss, postoperative complications, or hospital stays. The mean operation time of the ALC group was shorter than that of the RSPC group (56.5 minutes vs. 94.8 minutes, P < 0.001). Although the pain scores reported on discharge day did not differ, the ALC group reported significantly lower immediate postoperative pain scores than the RSPC group (2.7 vs. 5.4, P < 0.001).
Conclusions
ALC is a safe and feasible procedure. ALC patients reported markedly lower immediate postoperative pain scores than RSPC patients, with comparable operative outcomes for estimated blood loss, hospital stay, and postoperative complication rates.

Background:
s/Aims: In recent years, many minimally invasive techniques have been introduced to reduce the number of ports in laparoscopic cholecystectomy (LC), offering benefits such as reduced postoperative pain and improved cosmetic outcomes. ArtiSential®is a new multi-degree-of-freedom articulating laparoscopic instrument that incorporates the ergonomic features of robotic surgery, potentially overcoming the spatial limitations of laparoscopic surgery. ArtiSential® LC can be performed using only two ports. This study aims to compare the surgical outcomes of ArtiSential® LC with those of single-fulcrum LC.
Methods:
This retrospective study compared ArtiSential® LC and single-fulcrum LC among LCs performed for gallbladder (GB) stones at the same center, analyzing the basic characteristics of patients; intraoperative outcomes, such as operative time, estimated blood loss, and intraoperative GB rupture; and postoperative outcomes, such as length of hospital stay, incidence of postoperative complications, and postoperative pain.
Results:
A total of 88 and 63 patients underwent ArtiSential® LC and single-fulcrum LC for GB stones, respectively. Analysis showed that ArtiSential® LC resulted in significantly fewer cases of surgeries longer than 60 minutes (30 vs. 35 min, p = 0.009) and intraoperative GB ruptures (2 vs. 10, p = 0.007). In terms of postoperative outcomes, ArtiSential® LC showed better results in the respective visual analog scale (VAS) scores immediately after surgery (2.59 vs. 3.73, p < 0.001), and before discharge (1.44 vs. 2.02, p = 0.01).
Conclusions
ArtiSential® LC showed better results in terms of surgical outcomes, especially postoperative pain. Thus, ArtiSential®LC is considered the better option for patients, compared to single-fulcrum LC.

This systematic review and meta-analysis aimed to evaluate the impact of prospective payment systems (PPSs) on cholecystectomy.A comprehensive literature review was conducted, examining studies published until December 2023. The review process focused on identifying research across major databases that reported critical outcomes such as length of stay (LOS), mortality, complications, admissions, readmissions, and costs following PPS for cholecystectomy. The studies were specifically selected for their relevance to the impact of PPS or the transition from fee-for-service (FFS) to PPS. The study analyzed six papers, with three eligible for meta-analysis, to assess the impact of the shift from FFS to PPS in laparoscopic and open cholecystectomy procedures. Our findings indicated no significant changes in LOS and mortality rates following the transition from FFS to PPS. Complication rates varied and were influenced by the diagnosis-related group categorization and surgeon cost profiles under episode-based payment. There was a slight increase in admissions and readmissions, and mixed effects on hospital costs and financial margins, suggesting varied responses to PPS for cholecystectomy procedures. The impact of PPS on cholecystectomy is nuanced and varies across different aspects of healthcare delivery.Our findings indicate a need for adaptable, patient-centered PPS models that balance economic efficiency with high-quality patient care. The study emphasizes the importance of considering specific surgical procedures and patient demographics in healthcare payment reforms.

Purpose:
NUF2 has been implicated in multiple cancers recently, suggesting NUF2 may play a role in the common tumorigenesis process. In this study, we aim to perform comprehensive meta-analysis of NUF2 expression in the cancer types included in the Cancer Genome Atlas (TCGA).
Materials and Methods:
RNA-sequencing data in 31 cancer types in the TCGA data and 11 independent datasets were used to examine NUF2 expression. Silencing NUF2 using targeting shRNAs in hepatocellular carcinoma (HCC) cell lines was used to evaluate NUF2’s role in HCC in vitro and in vivo.
Results:
NUF2 up-regulation is significantly observed in 23 out of the 31 cancer types in the TCGA datasets and validated in 13 major cancer types using 11 independent datasets. NUF2 overexpression was clinically important as high NUF2 was significantly associated with tumor stages in eight different cancers. High NUF2 was also associated with significantly poorer patient overall survival and disease-free survival in eight and six cancers, respectively. We proceeded to validate NUF2 overexpression and its negative association with overall survival at the protein level in an independent cohort of 40 HCC patients. Compared to the non-targeting controls, NUF2 knockdown cells showed significantly reduced ability to grow, migrate into a scratch wound and invade the 8 μm porous membrane in vitro. Moreover, NUF2 knockdown cells also formed significantly smaller tumors than control cells in mouse xenograft assays in vivo.
Conclusion
NUF2 up-regulation is a common feature of many cancers. The prognostic potential and functional impact of NUF2 up-regulation warrant further studies.
