Background: Several devices are available for liver parenchyma transection (LPT). The aim of this study was to compare the Ultracision Harmonic scalpel (UHS) with the Cavitron Ultrasonic Surgical Aspirator (CUSA) among patients who underwent hemi-right hepatectomies (RH) to homogenize transection areas. Methods: From September 2012 to June 2015, 24 patients who underwent the UHS surgery approach were matched with 24 patients who underwent the CUSA transection procedure for RH using propensity score matching. Results: Total operative time (TOT) was shorter in the UHS group, 240 minutes (range 172.5-298.8) versus 330 minutes (range 270-400) in the CUSA group ( P = .0002). The occurrence of hepatopathy (odds ratio = 17; 95% confidence interval = 1.02-230) and the use of the CUSA device (odds ratio = 8; 95% confidence interval = 0.98-77) were associated with a TOT exceeding 300 minutes in multivariate analysis ( P = .05). Conclusions: The UHS is a safe and effective method of LPT as compared to the use of the CUSA system. TOT is statistically decreased.

Abstract Background and study aims Although endoscopic transpapillary gallbladder drainage (ETGBD) is reportedly useful in patients who have acute cholecystitis, its efficacy has not been compared to that of percutaneous transhepatic gallbladder drainage (PTGBD). We retrospectively compared the efficacy and safety of ETGBD and PTGBD in patients with acute cholecystitis. Patients and methods We studied 75 patients who required gallbladder drainage for acute cholecystitis between January 2014 and December 2016. Using propensity score matching analysis, we compared the clinical efficacy and length of hospitalization in patients successfully treated with ETGBD and PTGBD. Moreover, we assessed the predictive factors for hospitalization period < 30 days using multivariate analysis. Results ETGBD and PTGBD were successfully performed in 33 patients (77 %) and 42 patients (100 %) (P < 0.001). Twenty-seven matched pairs were obtained after propensity score matching analysis. No significant differences were observed between patients treated with ETGBD and those treated with PTGBD with respect to improvement in white blood cell count and serum C-reactive protein level. The length of hospitalization in patients treated with ETGBD was significantly shorter than in those treated with PTGBD regardless of the need for surgery. Multivariate logistic regression analysis revealed ETGBD (odds ratio, 7.07; 95 % confidence interval 2.22 – 22.46) and surgery (odds ratio 0.26; 95 % confidence interval 0.09 – 0.79) as independent factors associated with hospitalization period. There were no significant differences in occurrence of complications in ETGBD and PTGBD procedure. Conclusions ETGBD was shown to be as useful as PTGBD for treatment of acute cholecystitis and was associated with shorter hospitalization period. ETGBD can be an alternative treatment option for acute cholecystitis at times when PTGBD is not possible.

Thus far, few studies have compared the effects of sugammadex and cholinesterase inhibitors on postoperative nausea and vomiting (PONV), and the results have been controversial. Here, we compared the effects of sugammadex, neostigmine, and pyridostigmine on PONV by means of a five hospital analysis with propensity score matching. We analyzed adults aged ≥ 18 years who underwent general anesthesia between January 2014 and December 2019. Following propensity score matching, 7793 patients were included in each of the neostigmine and sugammadex matched patient groups (absolute standardized difference (ASD), 0.01–0.07), and 10,197 patients were included in each of the pyridostigmine and sugammadex matched patient groups (ASD, 0.01–0.02), while 19,377 patients were included in each of the pyridostigmine and neostigmine matched patient groups. (ASD, 0.01–0.19). The odds of PONV were low in the sugammadex group (odds ratio, 0.65; 95% confidence interval, 0.59–0.72; p < 0.0001) and pyridostigmine group (odds ratio, 0.22; 95% confidence interval, 0.20–0.24; p < 0.0001) compared to the neostigmine group, while there was no difference between sugammadex and pyridostigmine (odds ratio, 0.95; 95% confidence interval, 0.86–1.04; p = 0.281). Therefore, sugammadex and pyridostigmine may lower the incidence of PONV compared to neostigmine in patients undergoing general anesthesia.

Background: Previous randomized controlled trials demonstrated the efficacy of targeted temperature management (TTM) in out-of-hospital cardiac arrest (OHCA) patients with both shockable and non-shockable rhythm. Real-world evidence for TTM using large OHCA database are scarce, and no study has investigated the relationship between TTM and time-to-return of spontaneous circulation (ROSC). Methods: The Japanese Association for Acute Medicine - out-of-hospital cardiac arrest (JAAM-OHCA) Registry is a multicenter, prospective, observational registry including 34,754 OHCA patients between 2014 and 2017. Patients with witnessed non-traumatic OHCA who had been resuscitated and were in a coma were included. Eligible patients were divided into two groups according to the use of TTM. The primary outcome was defined as a Cerebral Performance Categories (CPC) Scale 1-2 at 30 days after OHCA. The propensity score matching analysis was used. The cubic spline analysis of the odds ratio of CPC 1-2 for TTM use by time-to-ROSC was performed. Results: Out of 34,754 patients with OHCA, 5,261 patients were included. The mean age was 70.3 years, and 3,417 (65.0%) were male. CPC 1-2 was more frequently observed in the TTM group in propensity score matching analysis (15.1% vs. 8.5%; odds ratio 1.92; 95% confidence interval 1.04-3.53; P=0.037). The cubic spline analysis showed that TTM was associated with CPC 1-2 in witnessed OHCA patients, which did not reach statistical significance in patients with time-to-ROSC longer than 50 min. Conclusions: TTM was associated with better neurological outcomes in witnessed OHCA patients, especially when patients were resuscitated within 50 min after collapse.

Abstract Background: Various hemostatic devices have been utilized to reduce blood loss during hepatectomy. Nonetheless, a comparison between monopolar and bipolar coagulation, particularly their usefulness or inferiority, has been poorly documented. The aim of this study is to reveal the characteristics of these hemostatic devices.Methods: A total of 264 patients who underwent open hepatectomy at our institution from January 2009 to December 2018 were included. Monopolar and bipolar hemostatic devices were used in 160 (monopolar group) and 104 (bipolar group) cases, respectively. Operative outcomes and thermal damage to the resected specimens were compared between these groups using propensity score matching according to background factors. Multivariate logistic regression analysis was performed to identify predictive factors for postoperative complications.Results: After propensity score matching, 73 patients per group were enrolled. The monopolar group had significantly lower total operative time (239 vs. 275 min; P=0.013) and intraoperative blood loss (487 vs. 790 mL; P<0.001). However, the incidence rates of ascites (27.4% vs. 8.2%; P=0.002) and grade ≥3 intra-abdominal infection (12.3% vs. 2.7%; P=0.028) were significantly higher in the monopolar group. Thermal damage to the resected specimens was significantly longer in the monopolar group (4.6 vs. 1.2 mm; P<0.001). Use of monopolar hemostatic device was an independent risk factor for ascites (odds ratio, 5.626, 95% confidence interval 1.881–16.827; P=0.002) and severe intra-abdominal infection (odds ratio, 5.905, 95% confidence interval 1.096–31.825; P=0.039).Conclusions: Although monopolar devices have an excellent hemostatic ability, they might damage the remnant liver. The use of monopolar devices can be one of the factors that increase the frequency of complications.
