Abstract	In this review article, we focus on recent papers on organ-preserving pancreatectomy procedures published since 2010. When comparing central pancreatectomy (CP) and distal pancreatectomy (DP), most studies have concluded that the CP group exhibited significantly lower incidence of new-onset diabetes or diabetes exacerbation than the DP group postoperatively. However, because of increased incidence of morbidities such as pancreatic fistula, the surgeon faces a considerable trade-off between increased short-term morbidity and long-term preservation of endocrine function. When the outcomes of two types of spleen-preserving DP (Kimura and Warshaw procedures) are compared, most studies mentioned the low incidence of postoperative gastric varices and splenic infarction with the Kimura procedure. Although there are several reports regarding the effect of spleen preservation on prevention of postoperative infections, no report on the contribution of spleen preservation to the prevention of overwhelming post-splenectomy infection is seen. The advantages of duodenum-preserving pancreatic head resection (DPPHR) concerning endocrine and exocrine functions continue to be subjects of discussion, mainly due to the limited number of institutions that have adopted this approach; however, DPPHR should be presented as an option for patients due to its low incidence of postoperative cholangitis. Organ-preserving pancreatectomy requires meticulous surgical techniques, and postoperative complications may increase with this surgery compared with standard pancreatectomy, which may be influenced by the surgeon's skill and the surgical facility where the procedure is performed. Nonetheless, this technique has significant long-term advantages in terms of endocrine and exocrine functions and its wider adoption in the future is expected.

Abstract	Purpose: The present study aimed to determine whether concomitant extrahepatic bile duct resection (EHBDR) improves the prognosis of patients with T2 gallbladder cancer (GBC). Methods: Between 2014 and 2018, 4947 patients with GBC were registered in the National Biliary Tract Cancer Registry in Japan. This included 3804 patients (76.9%) who underwent curative-intent surgical resection; 1609 of these patients had pT2 GBC with no distant metastasis. Of the 1609 patients with GBC, 520 underwent EHBDR and 1089 did not. We compared the patients' backgrounds and disease-specific survival rates between the groups. Results: The frequency of lymph node metastasis was significantly higher in the EHBDR group than in the non-EHBDR group (38.2% vs. 20.7%, p < .001). In the entire cohort, however, there was no significant difference in disease-specific survival between the two groups (76% vs. 79%, p = .410). The EHBDR group had a significantly higher incidence of postoperative complications (Clavien-Dindo classification grade = 3) (32.4% vs. 11.7%, p < .001). When we focused on the survival of only T2N1 patients who underwent gallbladder bed resection, the prognosis was significantly improved for the EHBDR group (5-year survival rate: 64% vs. 54%, p = .017). The non-EHBDR group was subcategorized into two groups: D2 dissection and D1 dissection or sampling, and survival curves were compared between these subgroups. Although the EHBDR group tended to have a favorable prognosis compared to the D2 group, this difference was not significant (p = .167). However, the EHBDR group had a significantly greater prognosis than the D1 dissection or sampling group (5 year-survival rate: 64 vs. 49%, p = .027). Conclusions: The EHBDR may improve the prognosis of patients with T2 gall bladder cancer with lymph node metastases; however, its indication should be carefully determined because of the increased risk of postoperative complications.

Abstract	Purpose: To describe the long-term quantitative change in the number of submissions of patient safety reports after the introduction of a patient safety reporting system, focusing on incident severity and type. Patients and methods: This study was performed at a tertiary care hospital in Japan. Patient safety reports from 2006 to 2020 were retrospectively reviewed. Incident severity was classified from level 0 (near miss) to level 5 (fatality). The incident types included those related to medication, patient care, drains and catheters, procedures and interventions, examinations, medical devices, and blood transfusions. The study period was divided into 1. 2004-2007; 2. 2008-2014; and 3. 2015-2020 based on the implementation of hospital patient safety strategies. The number of reports per hospital worker was compared among the study periods and the incident levels and types. Results: We analyzed 96,332 reports extracted from the patient safety reporting system of the hospital. The total number of reports per hospital worker has increased over time. The numbers of levels 0 and 1 incidents increased throughout the study period. In addition, levels 3a and 3b incidents increased between periods 2 and 3. All incident types, except for procedure and intervention-related incidents, increased between periods 1 and 2 and between periods 1 and 3. The number of procedure and intervention-related incidents increased between periods 2 and 3, although it did not between periods 1 and 2. Conclusion: We found increases in the number of patient safety reports according to the incident severity and type. This suggests two contextual changes occurring during the cultural maturity process, which reflected the development of organizational patient safety culture in our institution. The first was the establishment of a reporting attitude in the institution. The second was to overcome barriers to patient safety.

Abstract	Background: Healthcare-related adverse events occur because of complex healthcare systems. The patient safety reporting system is a core component of patient safety initiatives in hospitals. However, hospital management often encounters a cultural barrier with its implementation and struggles to overcome the same. Implementation science would be useful for analysing implementation strategies. This study determines the effects of the implemented strategy on an increase in the number of patient safety reports and the determinants of successful implementation, using the implementation framework. Methods: Mixed method analysis was performed in Fujita Health University Hospital (FHUH), a large volume hospital in Japan. We identified strategies to implement the patient safety reporting system by scrutinising internal documents using the Consolidated Framework for Implementation Research (CFIR). The electronic reporting systems developed in 2004 in the FHUH and the number of reports were analysed using the staff data and hospital volumes. Results: Reports (n = 110,058) issued between April 2004 and March 2020 were analysed. The number of reports increased from 2004 to 2008 and from 2013 to 2019, reaching 14,037 reports per year. Between 2009 and 2012, the FHUH experienced a stagnation period where the number of reports were not increasing. From the qualitative materials, we identified 74 strategies which contributed to the implementation of the patient safety reporting system. Among these, the domain of 'intervention characteristics' in the CFIR contained 12 strategies, 'outer settings' contained 20, 'inner settings' contained 21, 'characteristics of individuals' contained 8, and 'process' contained 13. There were two concentrated periods of the implemented strategies, the number was 17 in 2007 and 10 in 2016. These concentrated periods preceded a remarkable increase in the number of patient safety reports. Conclusions: A safety culture had been fostered in FHUH in the study period. A relationship between number of strategies and development of a reporting culture was observed. The intensity of adequate strategies was needed for implementation of patient safety reporting system. Therefore, the implementation framework is useful for analysing patient safety initiatives for safety culture.

Abstract	Recurrence of liver cancers after liver resection (LR), such as recurrences of hepatocellular carcinoma and colorectal liver metastases, is often treated with repeat LR (RLR) as the only curative treatment. However, RLR is associated with an increased risk of complications. The indications for the currently emerging laparoscopic LR and its advantages and disadvantages for repeat treatment are still under discussion. Our multi-institutional propensity-score matched analyses of laparoscopic vs. open RLRs for hepatocellular carcinoma showed the feasibility of laparoscopic RLR with comparable short- and long-term outcomes. Small blood loss and low morbidity was observed in selected patients treated using laparoscopic RLR in which total adhesiolysis can be dodged, with speculations that laparoscopic minor repeated LR can minimize functional deterioration of the liver. However, there are several disadvantages, such as easily occurring disorientation and difficulty in repeated wide-range dissection of Glissonian pedicles. Recently emerging small anatomical resection, indocyanine green fluorescence-guided surgery, and robot-assisted surgery are promising tools for the further development of laparoscopic RLR. This review discusses how laparoscopic RLR, as a powerful unique local therapy causing less damage to the residual liver and surrounding structures, could contribute to the outcomes of repeated treatments for cancers and its future perspectives.

Abstract	Overall survival of patients with localized pancreatic ductal adenocarcinoma (PDAC) is extremely poor. Therefore, the establishment of multimodal treatment strategies is indispensable for PDAC patients because surgical treatment alone could not contribute to the improvement of survival. In this review article, we focus on the current topics and advancement of the treatments for localized PDAC including resectable, borderline resectable, and locally advanced PDAC in accordance with the articles mainly published from 2019 to 2020. Reviewing the articles, the recent progress of multimodal treatments notably improves the prognosis of patients with localized PDAC. For resectable PDAC, neoadjuvant chemo or chemoradiation therapy, rather than upfront surgery, plays a key role, especially in patients with a large tumor, poor performance status, high tumor marker levels, peripancreatic lymph nodes metastasis, or neural invasion suspected on preoperative imaging. For borderline resectable PDAC, neoadjuvant treatments followed by surgery is a desirable approach, and maintenance of immunonutritional status during the treatments are also important. For locally advanced disease, conversion surgery has a central role in improving a survival outcome; however, its indication should be standardized.

Abstract	We had reported the novel concept of "caudal approach in laparoscopic liver resection" in 2013. In the first report, the caudal approach of laparoscopic transection-first posterior sectionectomy without prior mobilization of the liver in the left lateral position was described. Thereafter, 10 complex laparoscopic extended posterior sectionectomies with combined resection of the right hepatic vein or diaphragm were performed using the same approach. In the present study, the short-term outcomes of these cases and 42 cases of laparoscopic sectionectomies or hemi-hepatectomies (excluding left lateral sectionectomy) were compared. There was no statistically significant difference between the groups in terms of patients' backgrounds, diseases for resection, preoperative liver function, tumor number and size, as well as outcomes, operation time, intraoperative blood loss, morbidity, conversion to laparotomy, and post-operative hospital stay. Even complex laparoscopic extended posterior sectionectomy was safely performed using this procedure. This approach has the technical benefits of acquiring a well-opened transection plane between the resected liver fixed to the retroperitoneum and the residual liver sinking to the left with the force of gravity during parenchymal transection, and less bleeding from the right hepatic vein due to its higher position than the inferior vena cava. Furthermore, it has an oncological benefit similar to that of the anterior approach in open liver resection, even in posterior sectionectomy. The detailed procedure and general conceptual benefits of the caudal approach to laparoscopic liver resection for repeated multimodal treatment for hepatocellular carcinoma are described.

Abstract	Background: This study aimed to investigate the effect of the use of new lithotomy stirrups-2 on the pressure dispersal on lower limbs, which may lead to the prevention of well-leg compartment syndrome (WLCS) and deep venous thrombosis (DVT), which are the most commonly associated adverse events with laparoscopic and robot-assisted rectal surgery. Methods: A total of 30 healthy participants were included in this study. The pressure (mmHg) applied on various lower limb muscles when using conventional lithotomy stirrups-1 and new type stirrups-2 was recorded in various lithotomy positions; 1) neutral position, 2) Trendelenburg position (15°) with a 0° right inferior tilt, and 3) Trendelenburg position (15°) with a 10° right inferior tilt. Using a special sensor pad named Palm Q®, and the average values were compared between two types of stirrups. Results: The use of new lithotomy stirrups-2 significantly reduced the pressure applied on the lower limb muscles in various lithotomy positions compared with the use of lithotomy stirrups-1. The most pressured lower limb muscle when using both lithotomy stirrups was the central soleus muscle, which is the most common site for the development of WLCS and DVT. In addition, when using the conventional lithotomy stirrups-1, the pressure was predominantly applied to the proximal soleus muscle; however, when using lithotomy stirrups-2, the pressure was shifted to the more distal soleus muscle. Conclusion: These results suggest that the new lithotomy stirrups-2 is useful in reducing the pressure load on leg muscles, especially on the proximal to central soleus, and may reduce the incidence of WLCS and DVT after rectal surgery performed in the lithotomy position. Further clinical studies are needed to determine whether the use of lithotomy stirrups-2 prevents these complications in various clinical settings.
