Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is a critical complication of laparoscopic gastrectomy (LG). However, there are no widely recognized anatomical landmarks to prevent POPF during LG. This study aimed to identify anatomical landmarks related to POPF occurrence during LG for gastric cancer and to develop an artificial intelligence (AI) navigation system for indicating these landmarks. METHODS Dimpling lines (DLs)-depressions formed between the pancreas and surrounding organs-were defined as anatomical landmarks related to POPF. The DLs for the mesogastrium, intestine, and transverse mesocolon were named DMP, DIP, and DTP, respectively. We included 50 LG cases to develop the AI system (45/50 were used for training and 5/50 for adjusting the hyperparameters of the employed system). Regarding the validation of the AI system, DLs were assessed by an external evaluation committee using a Likert scale, and the pancreas was assessed using the Dice coefficient, with 10 prospectively registered cases. RESULTS Six expert surgeons confirmed the efficacy of DLs as anatomical landmarks related to POPF in LG. An AI system was developed using a semantic segmentation model that indicated DLs in real-time when this system was synchronized during surgery. Additionally, the distribution of scores for DMP was significantly higher than that of the other DLs (p < 0.001), indicating the relatively high accuracy of this landmark. In addition, the Dice coefficient of the pancreas was 0.70. CONCLUSIONS The DLs may be used as anatomical landmarks related to POPF occurrence. The developed AI navigation system can help visualize the DLs in real-time during LG.

Relationship between hospital surgical volume and the perioperative esophagectomy costs for esophageal cancer: a nationwide administrative claims database study. Esophagus 2024:10.1007/s10388-024-01092-6. [PMID: 39347879 DOI: 10.1007/s10388-024-01092-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Accepted: 09/16/2024] [Indexed: 10/01/2024]
Abstract
BACKGROUND Numerous studies have described positive relationships between hospital volume (HV) and clinical outcomes in highly complex procedures, including esophagectomies. Although the centralization of surgery has been considered a possible solution for improving clinical outcomes, the HV impact on perioperative healthcare costs is unknown. This study aimed to determine the relationship between HV and perioperative healthcare costs for patients undergoing esophagectomy for esophageal cancer. METHODS This retrospective, nationwide cohort study used Japanese Administrative Claims Database data. Data on esophagectomies performed nationwide in 2015 were extracted. The outcome measure was perioperative healthcare costs per person from the perspective of the insurer. The healthcare costs in outpatient or inpatient settings of any hospital and clinic where patients received treatment were summed up from the month the surgery was performed to 3 months after. Linear regression analyses were conducted to assess the risk-adjusted effects of the HV category (1-4/5-9/10-14/15-) on perioperative costs. RESULTS A total of 5232 patients underwent an esophagectomy at 584 hospitals. The overall perioperative cost was 20.834 billion Japanese yen (JPY). The median perioperative costs per person for each HV category (1-4/5-9/10-14/15-) were 3.728 (709 patients), 3.740 (658 patients), 3.760 (512 patients), and 3.760 (3253 patients) million JPY, respectively (P = 0.676). Multivariate analyses revealed that each HV category had no significant impact on perioperative costs. CONCLUSIONS There were no significant differences in the perioperative costs between high- and low-volume centers. Esophageal cancer surgery centralization may be achievable without increasing healthcare costs.

The development of a risk assessment tool for patients with postoperative pneumonia after gastrectomy for gastric cancer. J Gastrointest Surg 2024; 28:359-364. [PMID: 38583884 DOI: 10.1016/j.gassur.2024.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 12/12/2023] [Accepted: 01/13/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Although frail patients are known to experience increased postoperative complications, this is unclear for postoperative pneumonia (POP). We investigated associations between frailty and POP in patients with gastric cancer (GC) undergoing gastrectomy. METHODS In this prospective study conducted between August 2016 and December 2022, we preoperatively assessed frailty in 341 patients with GC undergoing gastrectomy using a frailty index (FI). Patients were divided into high FI vs low FI groups to examine frailty and pneumonia rates after gastrectomy for GC. RESULTS Of 327 patients, 18 (5.5%) experienced POP after gastrectomy. Multivariate analyses showed that a high FI and total or proximal gastrectomy (TG/PG) were independent risk factors for POP (high FI: odds ratio [OR], 5.00; 95% CI, 1.77-15.54; TG/PG: OR, 3.07; 95% CI, 1.09-8.78). The proportion of patients with POP was 2.4% in those with nonhigh FI and non-TG/PG, 5.3% in those with nonhigh FI and TG/PG, 7.1% in those with high FI and non-TG/PG, and 28.0% in those with high FI and TG/PG (P < .001). The area under the receiver operating characteristic curve for this risk assessment for predicting POP was 0.740. CONCLUSION In patients with GC undergoing gastrectomy, POP was independently associated with preoperatively high FI and TG/PG. Our simple POP risk assessment method, which combines these factors, may effectively predict and prepare patients for POP.

Effects of postoperative oral elemental nutritional supplement on skeletal muscle loss after gastrectomy for gastric cancer. Int J Clin Oncol 2024; 29:266-275. [PMID: 38227091 DOI: 10.1007/s10147-023-02462-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Accepted: 12/15/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND We previously showed that daily nutritional intervention with an oral elemental diet (ED) at 300 kcal/day for 6-8 weeks postoperatively decreased the percentage of body weight loss (%BWL), and that the effect was maintained for 1 year. This post hoc analysis aimed to determine whether this intervention decreased skeletal muscle mass loss 1-year post-gastrectomy. METHODS Data from consecutive, untreated patients with histopathologically confirmed stage I-III gastric adenocarcinoma who planned to undergo total gastrectomy (TG) or distal gastrectomy (DG) and were enrolled in a previously published randomized trial were used. The primary endpoint was the percentage of skeletal muscle mass index (%SMI) loss from baseline at 1 year postoperatively, based on abdominal computed tomography images obtained preoperatively and at 1 year postoperatively. RESULTS The overall median %SMI loss was lower in the ED versus control group, but the difference was not significant. The difference in %SMI loss in the ED and control groups was greater in patients with TG (10.1 vs. 13.0; P = 0.12) than in those with DG (5.5 vs. 6.8; P = 0.69). A correlation was observed between %BWL and %SMI loss in both groups (ED group, coefficient 0.591; control group, coefficient 0.644; P < 0.001 for both). Type of gastrectomy (coefficient 7.38; P = 0.001) and disease stage (coefficient - 6.43; P = 0.04) were independent predictors of postoperative skeletal muscle mass loss. CONCLUSION ED administration for 6-8 weeks following gastrectomy had no inhibitory effect on skeletal muscle loss at 1 year postoperatively. CLINICAL TRIAL REGISTRATION UMIN000023455.

Abstract
PURPOSE Although reports suggest that the pancreatic volume decreases after gastrectomy for gastric cancer, the relationship between the pancreatic volume and secretory function after gastrectomy remains unclear. In this study, we examined the relationship between the pancreatic volume and exocrine and endocrine functions after total gastrectomy. METHODS The pancreatic volumes of 18 distal gastrectomy and 15 total gastrectomy patients were retrospectively measured using computed tomography volumetry up to 5 years postoperatively. Ten low anterior resection patients were selected as controls. In addition, the pancreatic volume and exocrine function evaluated by fecal elastase and the insulin secretory function evaluated by glucagon tolerance testing were prospectively examined before and one year after surgery in nine cases of total gastrectomy. RESULTS After low anterior resection, the pancreatic volume did not change, but after distal and total gastrectomy, the pancreatic volume decreased continuously until the fifth year. After total gastrectomy, fecal elastase decreased significantly from 865.8 μg/g to 603.2 μg/g in the first year (p = 0.0316), and the insulin secretion capacity also decreased significantly from 3.83 ng/mL to 2.26 ng/mL (p = 0.0019). CONCLUSIONS The pancreatic volume decreases continuously after gastrectomy for gastric cancer, and the pancreatic exocrine and endocrine functions decrease along with pancreatic atrophy after total gastrectomy.

Abstract
Resection is the only potential curative treatment for perihilar cholangiocarcinoma (PHC); however, complete resection is often technically challenging due to the anatomical location. Various innovative approaches and procedures were invented to circumvent this limitation but the rates of postoperative morbidity (20%-78%) and mortality (2%-15%) are still high. In patients diagnosed with resectable PHC, deliberate and coordinated preoperative workup and optimization of the patient and future liver remnant are crucial. Biliary drainage is recommended to relieve obstructive jaundice and optimize the clinical condition before liver resection. Biliary drainage for PHC can be performed either by endoscopic biliary drainage or percutaneous transhepatic biliary drainage. To date there is no consensus about which method is preferred. The volumetric assessment of the future remnant liver volume and optimization mainly using portal vein embolization is the gold standard in the management of the risk to develop post hepatectomy liver failure. The improvement of systemic chemotherapy has contributed to prolong the survival not only in patients with unresectable PHC but also in patients undergoing curative surgery. In this article, we review the literature and discuss the current surgical treatment of PHC.

Abstract
BACKGROUND The present study aimed to evaluate the association between estimated functional remnant pancreatic volume (eFRPV) and postoperative malnutrition after pancreaticoduodenectomy (PD). METHODS The medical records of 131 patients who underwent PD and preoperative computed tomography were retrospectively reviewed. Onodera's prognostic nutritional index (PNI) was assessed 6-months after PD. Patients with PNI values of at least 45 were included in the non-malnutrition group, while those with values <45 and <40 were included in the mild and severe malnutrition groups, respectively. Associations between eFRPV and postoperative nutritional status were evaluated to identify factors predictive of severe malnutrition after PD. RESULTS Fifty-three patients (40%) were included in the non-malnutrition group, while 38 (29%) and 40 (31%) were included in the mild and severe malnutrition groups, respectively. Overall survival was significantly shorter in the severe malnutrition group (p < 0.001). The eFRPV was significantly lower in the severe malnutrition group (p = 0.003; Jonckheere-Terpstra trend test, p < 0.001). In the multivariate analysis, eFRPV ≤55.2 mL·HU (odds ratio [OR] = 5.20; p = 0.004), preoperative PNI ≤41.9 (OR = 6.37; p = 0.010), and body mass index ≤19.1 kg/m2 (OR = 3.43; p = 0.031) were independent predictors of severe malnutrition after PD. CONCLUSION The current results indicate that eFRPV may predict low PNI values after PD.

Abstract
Aim This study aimed to evaluate the impact of the coronavirus disease (COVID-19) pandemic on elective endoscopic surgeries in Japan using the National Clinical Database. Methods We retrospectively analyzed the clinicopathological factors and surgical outcomes of laparoscopic cholecystectomy (LC), laparoscopic distal gastrectomy (LDG), and laparoscopic low anterior resection (LLAR) and compared the monthly numbers of each procedure performed in 2020 with those in 2018 and 2019. The degree of infection in prefectures was classified into low and high groups. Results In 2020, the number of LCs (except for acute cholecystitis) was 76 079 (93.0% of that in 2019), the number of LDGs was 14 271 (85.9% of that in 2019), and the number of LLARs was 19 570 (88.1% of that in 2019). Although the number of robot-assisted LDG and LLAR cases increased in 2020, the growth rate was mild compared with that in 2019. There was little difference in the number of cases in the degree of infection in the prefectures. The numbers of LC, LDG, and LLAR cases decreased from May to June and recovered gradually. In late 2020, the proportion of T4 and N2 cases of gastric cancer and the number of T4 cases of rectal cancer increased compared with those in 2019. There was little difference between the proportions of postoperative complications and mortality in the three procedures between 2019 and 2020. Conclusion The number of endoscopic surgeries decreased in 2020 as a result of the COVID-19 pandemic. However, the procedures were performed safely in Japan.

Abstract
Aim The National Clinical Database (NCD) of Japan is a nationwide data entry system for surgery, and it marked its 10th anniversary in 2020. The aim was to present the 2020 annual report of gastroenterological surgery of the NCD. Methods The data of the surgical procedures stipulated by the training curriculum for board-certified surgeons of the Japanese Society of Gastroenterological Surgery in the NCD from 2011 to 2020 were summarized. Results In total, 5 622 845 cases, including 593 088 cases in 2020, were extracted from the NCD. The total number of gastroenterological surgeries increased gradually in these 10 years, except for the year 2020 due to the COVID-19 pandemic. The annual number of surgeries of each organ, except the pancreas and liver, decreased by 0.4%-13.1% in 2020 compared to 2019. The surgical patients were consistently aging, with more than 20% of all gastroenterological surgeries in 2020 involving patients aged 80 years or older. The participation of board-certified surgeons increased for each organ (75.9%-95.7% in 2020). The rates of endoscopic surgery also increased constantly. Although the incidences of postoperative complications of each organ increased by 0.7%-7.9% in these 10 years, postoperative mortality rates decreased by 0.2%-1.5%. Conclusions We present here the short-term outcomes of each gastroenterological operative procedure in 2020. This review of the 10-years of NCD data of gastroenterological surgery revealed a consistent increase of the number of surgeries (except for in 2020), especially endoscopic procedures, and aging of the Japanese population. The good safety of Japanese gastroenterological surgeries was also indicated.

Ulcer Scarring in the Gastric Conduit Is a Risk Factor for Anastomotic Leakage After Esophagectomy for Esophageal Cancer. J Gastrointest Surg 2023; 27:250-261. [PMID: 36509899 DOI: 10.1007/s11605-022-05545-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 11/19/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Anastomotic leakage (AL) is a serious complication after esophagectomy for esophageal cancer. The objective of this study was to identify the risk factors for AL. METHODS Patients with esophageal cancer who underwent curative esophagectomy and cervical esophagogastric anastomosis between 2009 and 2019 (N = 346) and those between 2020 and 2022 (N = 17) were enrolled in the study to identify the risk factors for AL and the study to assess the association between the risk factors and blood flow in the gastric conduit evaluated by indocyanine green (ICG) fluorescence imaging, respectively. RESULTS AL occurred in 17 out of 346 patients (4.9%). Peptic or endoscopic submucosal dissection (ESD) ulcer scars were independently associated with AL (OR 6.872, 95% CI 2.112-22.365) in addition to diabetes mellitus. The ulcer scars in the anterior/posterior gastric wall were more frequently observed in patients with AL than in those without AL (75.0% vs. 17.4%, P = 0.042). The median flow velocity of ICG fluorescence in the gastric conduits with the scars was significantly lower than in those without the scars (1.17 cm/s vs. 2.23 cm/s, P = 0.004). CONCLUSIONS Peptic or ESD ulcer scarring is a risk factor for AL after esophagectomy in addition to diabetes mellitus. The scars in the anterior/posterior gastric wall are significantly associated with AL, impairing blood flow of the gastric conduit. Preventive interventions and careful postoperative management should be provided to minimize the risk and severity of AL in patients with these risk factors.

Volume- and quality-controlled certification system promotes centralization of complex hepato-pancreatic-biliary surgery. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2023. [PMID: 36706938 DOI: 10.1002/jhbp.1307] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 12/26/2022] [Accepted: 01/19/2023] [Indexed: 01/29/2023]
Abstract
BACKGROUND Centralization of complex surgeries has made little progress when it only considers the minimum number of surgical procedures. We aim to assess the impact of certification system of Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS) on centralization and surgical quality of advanced hepato-pancreatic-biliary (HPB) surgery. METHODS The National Clinical Database was used to review 20 111 patients who underwent pancreatoduodenectomy (PD) and 9666 who underwent advanced hepatectomy defined as hepatectomy of more than one section during 2019 and 2020. JSHPBS certifies hospitals based on the annual number of advanced HPB surgeries and the surgical quality. Minimum numbers of surgeries for board-certified A and B institutions are 50 and 30, respectively. Short-term outcomes were compared among institutions. RESULTS In 2020, 69.4% (7007/10090) and 72.9% (3433/4710) of patients underwent PD and advanced hepatectomy at board-certified institutions. In-hospital mortality rates after PD was 0.9% at certified A institutions, 1.4% at B institutions, and 2.7% at non-certified institutions (p < .001). The odds ratio (OR) of risk-adjusted mortality after PD compared with non-certified institutions was 0.39 (confidence interval [CI]: 0.30-0.50, p < .001) at certified A institutions, and 0.54 at certified B institutions (CI: 0.40-0.73, p < .001). In-hospital mortality rates after advanced hepatectomy was 1.7% at certified A institutions, 2.3% at B institutions, and 3.2% at non-certified institutions (p < .001). The OR of risk-adjusted mortality after advanced hepatectomy compared with non-certified institutions was 0.57 at certified A institutions (CI: 0.41-0.78, p < .001). CONCLUSION The volume- and quality-controlled certification system of JSHBPS reduces surgical mortality after advanced HPB surgeries.

Risk factors associated with hypoglycemic events after total pancreatectomy: A nationwide multicenter prospective study in Japan. Surgery 2022; 172:962-967. [PMID: 35820975 DOI: 10.1016/j.surg.2022.04.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 03/27/2022] [Accepted: 04/25/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND The number of total pancreatectomy cases have increased worldwide, expanding the need for new insulin products and high-titer pancrelipases. However, the current data that is focused on hypoglycemic events after a total pancreatectomy from large nationwide series are still lacking. This study is aimed to assess the risk factors associated with hypoglycemic events after a total pancreatectomy. METHODS Data were prospectively collected from 216 consecutive patients who underwent total pancreatectomies between August 2015 and December 2017 from 68 Japanese centers. Of the 216 patients, 166 with a follow-up period of 1 year were analyzed. The risk factors for hypoglycemic events at 6 and 12 months (postoperative months 6 and 12) were investigated based on the results of a nationwide multicenter prospective study. RESULTS Of the 166 patients, 57 (34%) and 70 (42%) experienced moderate or severe hypoglycemic events or hypoglycemia unawareness on a monthly basis at postoperative months 6 and 12, respectively. Multivariate analysis revealed that body weight loss after surgery ≥0.3 kg and total cholesterol level ≤136 mg/dL at postoperative month 6, and glycated hemoglobin level ≤8.9% and rapid-acting insulin use at postoperative month 12 were independent risk factors for hypoglycemic events after a total pancreatectomy. There were different independent risk factors depending on the postoperative period. CONCLUSION Patients with body weight loss after surgery, low total cholesterol level, strict glycemic control, and using rapid-acting insulin should be aware of the occurrence of hypoglycemic events after their total pancreatectomy. In order to prevent hypoglycemic events after a total pancreatectomy, we need to consider optimal nutritional and glycemic control according to the postoperative period.

Emergency appendectomy versus elective appendectomy following conservative treatment for acute appendicitis: a multicenter retrospective clinical study by the Japanese Society for Abdominal Emergency Medicine. Surg Today 2022; 52:1607-1619.

Abstract
PURPOSE To establish the best treatment strategy for acute appendicitis. METHODS We collected data on 2142 appendectomies performed in 2017 and compared the backgrounds and surgical outcomes of patients who underwent early surgery (ES) (< 48 h) with those managed with non-ES (> 48 h). We performed a risk factor analysis to predict postoperative complications and subgroup analysis to propose a standard treatment strategy. RESULTS The incidence of postoperative complications was significantly higher in the ES group than in the non-ES group, and significantly lower in the laparoscopic surgery group than in the laparotomy group. Surgical outcomes, including the incidence of postoperative complications, were comparable after acute surgery (< 12 h) and subacute surgery (12-48 h), following antibiotic treatment. The risk factors for postoperative complications in the ES group were a higher age, history of abdominal surgery, perforation, high C-reactive protein level, histological evidence of gangrenous or perforated appendicitis, a long operation time, and intraoperative complications. The risk factors for postoperative complications in the non-ES group were perforation and unsuccessful conservative treatment. CONCLUSIONS Non-early appendectomy is feasible for acute appendicitis but should be applied with care in patients with risk factors for postoperative complications or failure of pretreatment, including diabetes mellitus, abscess formation, and perforation.

Abstract
BACKGROUND We aimed to present the 2019 annual report of the gastroenterological section of the National Clinical Database (NCD). METHODS We reviewed 609,589 cases recorded in 2019 and 5,029,764 cases registered from 2011 to 2019 for the 115 selected gastroenterological surgical procedures. RESULTS The main features of gastroenterological surgery in Japan were similar to those described in the 2018 annual report, namely, that 1) operative numbers gradually increased in all procedures, except gastrectomy and hepatectomy, which decreased in these years; 2) in all eight major gastroenterological surgeries, the age distribution tended toward older patients; 3) the morbidity of esophagectomy, hepatectomy, and pancreaticoduodenectomy increased, but mortality was minimized in all procedures; 4) all eight major gastroenterological procedures have increasingly been performed under laparoscopy; and 5) board-certified surgeons were increasingly involved. These trends in recent years were more prominent in 2019. CONCLUSIONS Thanks to the continuous cooperation and dedication of the surgeons, medical staff, and surgical clinical reviewers who registered the clinical data into the NCD, it is possible to understand the comprehensive landscape of surgery in Japan and to disclose new evidence in this field. The Japanese Society of Gastroenterological Surgery will continue to promote the value of this database and encourage the use of feedback and clinical studies using the NCD, now and in the future. Generating further approaches to surgical quality improvement are important directions for future research.

Impact of Primary Tumor Resection on Mortality in Patients with Stage IV Colorectal Cancer with Unresectable Metastases: A Multicenter Retrospective Cohort Study. World J Surg 2021; 45:3230-3239. [PMID: 34223985 DOI: 10.1007/s00268-021-06233-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/18/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Primary tumor resection (PTR) before commencing systemic chemotherapy in patients with stage IV colorectal cancer and unresectable metastases (mCRC) remains controversial. This study aimed to assess whether PTR before systemic chemotherapy is associated with mortality in mCRC patients, after adjusting for confounding factors, such as the severity of the primary tumor and metastatic lesions. METHODS We analyzed hospital-based cancer registries from nine designated cancer hospitals in Fukushima Prefecture, Japan. Patients were divided into two groups (PTR and non-PTR), based on whether PTR was performed as initial therapy for mCRC or not. The primary outcome was all-cause mortality. Kaplan-Meier survival analysis was performed, and survival estimates were compared using the log-rank test. Adjusted hazard ratios were calculated using Cox regression to adjust for confounding factors. All tests were two-sided; P-values < 0.05 were considered statistically significant. RESULTS Between 2008 and 2015, 616 mCRC patients were included (PTR: 414 [67.2%]; non-PTR: 202 [32.8%]). The median follow-up time was 18.0 (interquartile range [IQR]: 8.4-29.7) months, and 492 patients (79.9%) died during the study period. Median overall survival in the PTR and non-PTR groups was 23.9 (IQR: 12.2-39.9) and 12.3 (IQR: 6.2-23.8) months, respectively (P < 0.001, log-rank test). PTR was significantly associated with improved overall survival (adjusted hazard ratio: 0.51; 95% confidence interval: 0.42-0.64, P < 0.001). CONCLUSIONS PTR before systemic chemotherapy in patients with mCRC was associated with improved survival.

Management of Hepatocellular Carcinoma in Japan: JSH Consensus Statements and Recommendations 2021 Update. Liver Cancer 2021; 10:181-223. [PMID: 34239808 PMCID: PMC8237791 DOI: 10.1159/000514174] [Citation(s) in RCA: 345] [Impact Index Per Article: 115.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 12/23/2020] [Indexed: 02/06/2023] Open
Abstract
The Clinical Practice Manual for Hepatocellular Carcinoma was published based on evidence confirmed by the Evidence-based Clinical Practice Guidelines for Hepatocellular Carcinoma along with consensus opinion among a Japan Society of Hepatology (JSH) expert panel on hepatocellular carcinoma (HCC). Since the JSH Clinical Practice Guidelines are based on original articles with extremely high levels of evidence, expert opinions on HCC management in clinical practice or consensus on newly developed treatments are not included. However, the practice manual incorporates the literature based on clinical data, expert opinion, and real-world clinical practice currently conducted in Japan to facilitate its use by clinicians. Alongside each revision of the JSH Guidelines, we issued an update to the manual, with the first edition of the manual published in 2007, the second edition in 2010, the third edition in 2015, and the fourth edition in 2020, which includes the 2017 edition of the JSH Guideline. This article is an excerpt from the fourth edition of the HCC Clinical Practice Manual focusing on pathology, diagnosis, and treatment of HCC. It is designed as a practical manual different from the latest version of the JSH Clinical Practice Guidelines. This practice manual was written by an expert panel from the JSH, with emphasis on the consensus statements and recommendations for the management of HCC proposed by the JSH expert panel. In this article, we included newly developed clinical practices that are relatively common among Japanese experts in this field, although all of their statements are not associated with a high level of evidence, but these practices are likely to be incorporated into guidelines in the future. To write this article, coauthors from different institutions drafted the content and then critically reviewed each other's work. The revised content was then critically reviewed by the Board of Directors and the Planning and Public Relations Committee of JSH before publication to confirm the consensus statements and recommendations. The consensus statements and recommendations presented in this report represent measures actually being conducted at the highest-level HCC treatment centers in Japan. We hope this article provides insight into the actual situation of HCC practice in Japan, thereby affecting the global practice pattern in the management of HCC.

Validation of data quality in a nationwide gastroenterological surgical database: The National Clinical Database site-visit and remote audits, 2016-2018. Ann Gastroenterol Surg 2021; 5:296-303. [PMID: 34095719 PMCID: PMC8164453 DOI: 10.1002/ags3.12419] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Revised: 11/24/2020] [Accepted: 12/03/2020] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND AND AIM In 2015, the Japanese Society of Gastroenterological Surgery (JSGS) initiated data verification in the gastroenterological section of the National Clinical Database (NCD) and reported high accuracy of data entry. Remote audits were introduced for data validation on a trial basis in 2016 and formally accepted into use in 2017-2018. The aim of this study was to audit the data quality of the NCD gastroenterological section for 2016-2018 and to confirm the high accuracy of data in remote audits. METHODS Each year, 45-46 hospitals were selected for audit. Twenty cases were randomly selected in each hospital, and the accuracy of patient demographic and surgical outcome data (46 items) was compared with the corresponding medical records obtained by visiting the hospital (site-visit audit) or by mailing data from the hospital to the JSGS office (remote audit). RESULTS A total of 136 hospitals were included, of which 88 (64.7%) had a remote audit, and 124 936 items were evaluated with an overall data accuracy of 98.1%. There was no significant difference in terms of data accuracy between site-visit audit and remote audit. Accuracy, sensitivity, and specificity of mortality were 99.7%, 89.7%, 100% for site-visit audits and 99.8%, 97.3%, 100% for remote audits, respectively. Mean time spent on data verification per case of remote audits was shorter than that of site-visit audits (10.0 minutes vs 13.7 minutes, P < 0.001). CONCLUSION The audits showed that NCD data are reliable and characterized by high accuracy. Remote audits may substitute site-visit audits.

Estimates of the effects of centralization policy for surgery in Japan: does centralization affect the quality of healthcare for esophagectomies? Surg Today 2021; 51:1010-1019. [PMID: 33660105 DOI: 10.1007/s00595-021-02245-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 10/17/2020] [Indexed: 12/25/2022]
Abstract
PURPOSE This study compared the quality of healthcare before and after implementation of a policy restructuring the healthcare delivery system and estimated the impact of centralization. METHODS We used the National Clinical Database to study patients undergoing esophagectomies from 2011 to 2016. We compared the effect of centralization based on the patient background, surgical mortality, and year of surgery. Difference-in-difference methods based on the generalized estimating equation logistic regression model were used for before-and-after comparisons after adjusting for patient-level expected surgical mortality. RESULTS In total, 34,640 cases were identified. More cases with risk factors were noted in ultra-low-volume hospitals, where 38.4% of cases in underpopulated areas were treated, than in higher volume facilities, and the operative mortality, readmission within 30 days and length of stay were worse among patients treated in these hospitals. In centralized prefectures, the number of cases per hospital increased over time (7.2 in 2011 to 9.5 in 2016) while the crude operative mortality tended to decrease (3.4% in 2011 to 1.8% in 2016). The difference-in-difference estimator was 0.856 (95% confidence interval: 0.639-1.147, p = 0.298). CONCLUSION The centralization of ultra-low-volume hospitals did not lead to a deterioration in the quality of care but rather an improving trend.

Comparison of 5-year postoperative outcomes after Billroth I and Roux-en-Y reconstruction following distal gastrectomy for gastric cancer: Results from a multi-institutional randomized controlled trial. Ann Gastroenterol Surg 2021; 5:93-101. [PMID: 33532685 PMCID: PMC7832962 DOI: 10.1002/ags3.12400] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/15/2020] [Accepted: 08/24/2020] [Indexed: 12/29/2022] Open
Abstract
AIM We previously reported in a randomized controlled trial that Billroth I and Roux-en-Y reconstructions were generally equivalent regarding body weight change and nutritional status 1 year after distal gastrectomy for gastric cancer. We describe the long-term follow-up data 5 years after distal gastrectomy. METHODS We analyzed consecutive gastric cancer patients who were randomly assigned to undergo Billroth I or Roux-en-Y reconstruction after distal gastrectomy. We evaluated body weight change, nutritional status, late complications, quality of life (QOL) using the European Organization for Research and Treatment of Cancer Core QOL Questionnaire, and dysfunction using the Dysfunction After Upper Gastrointestinal Surgery for Cancer, 5 years after surgery. RESULTS A total of 228 patients (Billroth I = 105; Roux-en-Y = 123) were eligible for efficacy analyses in this study. Body weight loss 5 years after surgery did not differ significantly between the Billroth I and Roux-en-Y groups (10.0% ± 7.9% and 9.6% ± 8.4%, respectively; P = .70). There were no significant differences in other aspects of nutritional status between the two groups. Reflux esophagitis occurred in 19.0% of the patients in the Billroth I group vs 4.9% in the Roux-en-Y group (P = .002). Regarding QOL, Billroth I was significantly inferior to Roux-en-Y on the diarrhea scale (Billroth I: 28.6, Roux-en-Y: 16.0; P = .047). Regarding dysfunction, no score differed significantly between the two groups. CONCLUSIONS Billroth I and Roux-en-Y reconstructions were generally equivalent regarding body weight change, nutritional status, and QOL 5 years after distal gastrectomy, although Roux-en-Y more effectively prevented reflux esophagitis and diarrhea.

Abstract
AIM This study aimed to evaluate the association between surgeons certified via the Endoscopic Surgical Skill Qualification System (ESSQS) of the Japan Society for Endoscopic Surgery (JSES) and surgical outcomes of laparoscopic distal gastrectomy (LDG) and laparoscopic low anterior resection (LLAR). METHODS Japanese National Clinical Database data on the patients undergoing LDG and LLAR between 2014-2016 were analyzed retrospectively. The proportion of cases performed by ESSQS-certified surgeons was calculated for each procedure, and clinicopathological factors with or without participation of ESSQS-certified surgeons as an operator were assessed. Then, effects of operations performed by ESSQS-certified surgeons on short-term patient outcomes were analyzed using generalized estimating equations logistic regression analysis. RESULTS There were 110 610 and 65 717 patients who underwent LDG and LLAR, respectively. The operations performed by ESSQS-certified surgeons in each procedure totaled 28 467 (35.3%) and 12 866 (31.2%), respectively. A multivariable logistic regression model showed that odds ratios of mortality for LDG and LLAR performed by ESSQS-certified surgeons were 0.774 (95% CI, 0.566-1.060, P = 0.108) and 0.977 (0.591-1.301, P = 0.514), respectively. Odds ratios for secondary endpoints of anastomotic leakage in LDG and LLAR performed by ESSQS-certified surgeons were 0.835 (95% CI, 0.723-0.964, P = 0.014) and 0.929 (0.860-1.003, P = 0.059), respectively, whereas that of ileus/bowel obstruction for LLAR performed by ESSQS-certified surgeons was 1.265 (1.132-1.415, P < 0.001). There were no significant associations between the two operations performed by ESSQS-certified surgeons and other factors such as mortality and overall complications. CONCLUSIONS ESSQS certification did not affect postoperative mortality following LDG and LLAR, but annual experience of laparoscopic surgery was associated with it. ESSQS certification may contribute to favorable outcomes regarding anastomotic leakage following LDG and LLAR.

Clinical outcome of laparoscopic vs open right hemicolectomy for colon cancer: A propensity score matching analysis of the Japanese National Clinical Database. Ann Gastroenterol Surg 2020; 4:693-700. [PMID: 33319160 PMCID: PMC7726676 DOI: 10.1002/ags3.12381] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 05/27/2020] [Accepted: 07/06/2020] [Indexed: 01/17/2023] Open
Abstract
AIM The advantages of laparoscopic right hemicolectomy over open surgery for colon cancer in general clinical practice are debated, as evidenced by the continued use of open surgery in a significant proportion of patients worldwide. This study aimed to assess and compare the clinical outcome of laparoscopic and open right hemicolectomy for colon cancer using data from the Japanese National Clinical Database. METHODS A total of 72 299 patients who underwent laparoscopic (n = 46 084) and open (n = 26 215) right hemicolectomy for colon cancer between 2014 and 2018 were enrolled in this retrospective study. Short-term outcome was compared between groups using propensity score matching analysis. RESULTS The incidence of overall postoperative morbidity ≥ Clavien-Dindo classification grade 3 was significantly higher in the open surgery group than the laparoscopic group (4.7% vs 3.2%, P < .001). The incidence of most individual morbidities, including surgical site infection, anastomotic leakage, and ileus, was higher in the open surgery group. Short-term outcomes, including intraoperative blood loss, postoperative hospital stay, reoperation rate, 30-day mortality, and in-hospital mortality, were superior in the laparoscopic group, except for operative time. Subgroup analyses showed that the incidence of postoperative morbidity was lower in the laparoscopic group for all prespecified subgroups. CONCLUSION Laparoscopic right hemicolectomy has an advantage over open surgery for colon cancer with respect to short-term outcome.

Geriatric Risk Prediction Models for Major Gastroenterological Surgery using the National Clinical Database in Japan: A Multicenter Prospective Cohort Study. Ann Surg 2020; 275:1112-1120. [PMID: 33065635 DOI: 10.1097/sla.0000000000004308] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVES To investigate the effect of geriatric variables on five newly added outcomes and create risk models for predicting these outcomes. SUMMARY BACKGROUND DATA Because there is a current lack of geriatric research focusing on geriatric outcomes using a national surgical database in Japan, there is a need to investigate outcomes associated with major gastroenterological surgery using these data. METHODS This multicenter prospective cohort study was conducted at 26 surgery departments across 21 institutions in Japan using the National Clinical Database (NCD) surgical registry. In total, 22 new geriatric variables were imported from the ACS NSQIP geriatric pilot study. The following five geriatric outcomes were defined: 1) postoperative delirium, 2) physical function on postoperative day 30, 3) fall risk on discharge, 4) discharge other than home with social service, and 5) functional decline on discharge, and geriatric risk prediction models for major gastroenterological surgery were created. RESULTS Between January 2018 and December 2018, data on 3,981 procedures from seven major gastroenterological surgeries were collected and analyzed. Older age and preoperative geriatric variables (Origin status from home, History of dementia, Use of mobility aid, Fall history, and Not competent on admission) were strongly associated with postoperative outcomes. Geriatric risk prediction models for these outcomes were created, with C-statistic values ranging from 0.74 to 0.90, demonstrating model validity and sufficiency of fit. CONCLUSIONS The risk models for the newly defined five geriatric outcomes that we created can be used in the decision-making process or provision of care in geriatric patients.

Risk factors for bile leakage: Latest analysis of 10 102 hepatectomies for hepatocellular carcinoma from the Japanese national clinical database. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2020; 28:556-562. [PMID: 32897639 DOI: 10.1002/jhbp.827] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 08/11/2020] [Accepted: 08/18/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND/PURPOSE The aim of this study was to identify risk factors for bile leakage in hepatic resections without biliary reconstructions using the large Japanese national clinical database (NCD). METHODS A total of 10 102 patients who had undergone hepatic resection involving more than one segment without biliary reconstructions for hepatocellular carcinoma during 2015-2017 were enrolled. Risk factors for bile leakage, with special reference to the type of hepatic resection, were identified by multivariable logistic regression analysis. RESULTS Bile leakage occurred in 726 patients (7.2%). Risk factors for bile leakage were as follows: male sex (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.04-1.58), diabetes mellitus (+) (OR 1.19, 95% CI 1.01-1.39), hemoglobin <10 g/dL (OR 1.4, 95% CI 1.02-1.93), albumin <3.5 g/dL (OR 1.3, 95% CI 1.03-1.63), central bisectionectomy (OR 3.8, 95% CI 2.81-5.13), left trisectionectomy (OR 3.6, 95% CI 2.10-6.15), right anterior sectionectomy (OR 2.07, 95% CI 1.58-2.72), and S5 or S8 segmentectomy (OR 1.33, 95% CI 1.00-1.77). CONCLUSION Central bisectionectomy, left trisectionectomy, and right anterior sectionectomy are high-risk types of hepatic resection for bile leakage.

Abstract
Laparoscopic right hemicolectomy (LRH) is utilized worldwide as one of the standard surgical treatments for right-sided colon cancer. However, there have been issues concerning its applicability, techniques, and trend. The present study aimed to elucidate the current status and trend of LRH by reviewing literature focusing on important issues associated with this surgery. Based on previous studies, LRH most likely provides better short-term outcomes and similar oncological outcomes compared to open surgery. Despite the increasing use of robotic approach in this surgery, it seems to have always been associated with longer operative times and greater hospital cost with limited advantage. Intracorporeal anastomosis seems to improve short-term outcomes, such as quicker recovery of bowel function, compared to extracorporeal anastomosis. However, it does not contribute to shorter hospital stay. With regard to dissection technique, various approaches, and landmarks have been advocated to overcome the technical difficulty in LRH. This difficulty is likely to be caused by anatomical variation, especially in venous structures. The superiority of one approach or landmark over another is still argued about due to the lack of large-scale prospective studies. However, deep understanding both of anatomical variation and characteristics of each approach would be of extreme importance to minimize adverse effects and maximize patient benefit after LRH.

Abstract
BACKGROUND Emergency gastrointestinal surgery, although rare, is known for its high mortality and morbidity. However, the risks of emergency surgery for gastrointestinal cancer have not been investigated in depth. This study aimed to investigate the impact of emergency surgery on mortality and morbidity in patients with gastrointestinal cancers and to identify associated risk factors. METHODS We extracted data from the National Clinical Database, a nationwide surgery registration system in Japan, for patients with gastrointestinal cancer who underwent esophageal resection, total gastrectomy, distal gastrectomy, right hemicolectomy, or low anterior resection between 2012 and 2017. The impacts of emergency surgery on 30-day mortality and incidence of overall postoperative complications were compared with those of non-emergency surgery. Risk factors for mortality and overall postoperative complications were then sought in patients who underwent emergency surgery. RESULTS Thirty-day mortality and incidence of overall postoperative complications were significantly higher in emergency surgeries for gastric, colon, and rectal cancers than in non-emergency surgeries (odds ratios 4.86-6.98 and 1.68-2.18, respectively; all P < .001). Various risk factors were identified in the group that underwent emergency surgery, including preoperative sepsis and lower body mass index. Some of the risk factors were common to all types of surgery and others were specific to a certain type of surgery. CONCLUSION The actual risk of emergency surgery and the risk factors for overall postoperative complications in emergency cases are shown to serve as a reference for postoperative management. Emergency surgery had an additional burden on patients depending on the type of surgery.

Abstract
The National Clinical Database (NCD) of Japan was established in 2010 with the board certification system. A joint committee of 16 gastroenterological surgery database-affiliated organizations has been nurturing this nationwide database and utilizing its data for various analyses. Stepwise board certification systems have been validated by the NCD and are used to improve the surgical outcomes of patients. The use of risk calculators based on risk models can be particularly helpful for establishing appropriate and less invasive surgical treatments for individual patients. Data obtained from the NCD reflect current developments in the surgical approaches used in hospitals, which have progressed from open surgery to endoscopic and robot-assisted procedures. An investigation of the data acquired by the NCD could answer some relevant clinical questions and lead to better surgical management of patients. Furthermore, excellent surgical outcomes can be achieved through international comparisons of the national databases worldwide. This review examines what we have learned from the NCD of gastroenterological surgery and discusses what future developments we can expect.

Is remnant pancreatic cancer after pancreatic resection more frequent in early-stage pancreatic cancer than in advanced-stage cancer? Ann Gastroenterol Surg 2020; 4:448-454. [PMID: 32724889 PMCID: PMC7382434 DOI: 10.1002/ags3.12340] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 03/18/2020] [Accepted: 04/03/2020] [Indexed: 01/08/2023] Open
Abstract
AIM As the prognosis of patients who undergo resection for pancreatic cancer has improved, reports of remnant pancreatic cancer after pancreatic cancer resection have been increasing. Previous studies regarding early-stage pancreatic cancer showed a high incidence of remnant pancreatic cancer in these patients. The aim of this study was to investigate the incidence of remnant pancreatic cancer according to the degree of progression of the initial pancreatic cancer. METHODS Patients who underwent partial pancreatic resection for primary pancreatic cancer were retrospectively reviewed and divided into an early-stage group and an advanced-stage group according to the stage of the initial cancer. Patient characteristics and long-term outcomes, including development of remnant pancreatic cancer, were compared between the two groups. RESULTS This study included 321 patients who underwent partial pancreatectomy for pancreatic cancer; 32 patients in the early-stage group and 289 patients in the advanced-stage group. Remnant pancreatic cancer developed in 19 patients (5.9%); seven patients (21.9%) in the early-stage group and 12 patients (4.5%) in the advanced-stage group. The cumulative incidence of remnant pancreatic cancer according to the Kaplan-Meier method was comparable between the two groups (5-year cumulative incidence: 20.6% vs 9.9%, early-stage group vs advanced-stage group; P = .1827). CONCLUSION Our results suggested that the potential for developing remnant pancreatic cancer was comparable between the early-stage and the advanced-stage groups. Therefore, the incidence of remnant pancreatic cancer may increase along with improved pancreatic cancer treatment.

Abstract
AIM To investigate the effectiveness of the institutional medical structure and of the implemented clinical practice guidelines for improving colon cancer surgical outcomes. METHODS We conducted a web-based questionnaire survey among departments registered at the National Clinical Database in Japan from October 2014 to January 2015 to assess the association between quality indicators (QIs), including structure and process indicators (clinical practice guideline adherence), and the risk-adjusted odds ratio for operative mortality (AOR) after right hemicolectomy for colorectal cancer during the study period. RESULTS Among the 2064 departments registering at least one colorectal surgery during the study period, we obtained responses from 814 departments (39.4%). Our analysis on data from 22 816 patients with right hemicolectomy demonstrated that three structural QIs (certification of training hospitals by the Japanese Society of Gastroenterological Surgery and the presences of board-certified gastroenterological and colorectal surgeons) were associated with significantly lower AOR (P < .001, P = .02, and P = .05, respectively). The "performed at the doctor's discretion" answer was associated with poorer short-term outcomes in six process QIs than other answers. CONCLUSION The board certification system for gastroenterological and colorectal surgeons and the adherence to the clinical guidelines improve the operative mortality after right hemicolectomy. It is desired to clarify the most suitable QIs to reduce the operative mortality after colorectal surgery.

Abstract
The National Clinical Database (NCD) of Japan grew rapidly, harvesting over 11 million cases of data between 2011 and 2018 from more than 5000 facilities. This is the Report of the NCD based upon gastrointestinal surgery information in 4 420 175 cases from 2011 to 2018. More than 70% of all gastrointestinal surgeries were performed at certified institutions, and the percentage of surgeries performed at certified institutions was particularly high for the esophagus (93.8% in 2018), liver (89.4%), pancreas (91.3%), and spleen (86.9%). Also, more than 70% of the surgeries were performed with the participation of the board-certified surgeon. As the patients have been getting older, the morbidities have been increasing. However, the mortalities have been kept at a low level. The rates of endoscopic surgery have been increasing year by year, especially high in low anterior resection (67.0%) and esophagectomy (61.0%). Nationwide, this database is surely expecting to ensure the quality of board certification system and surgical outcomes in gastroenterological surgery.

Abstract
PURPOSE Perianastomotic fluid collection (PFC) is one of the postoperative complications of pancreaticoduodenectomy (PD). However, no studies have investigated the clinical significance of PFC location and volume during the early postoperative period. This study aimed to assess the association between PFC during the early postoperative period and postoperative complications. METHODS Medical records of 148 patients who had undergone PD and computed tomography (CT) on postoperative day 4 were retrospectively reviewed. The location-superior, inferior, ventral, dorsal, or splenic hilum-and PFC index, which is the estimated volume of fluid collection, were determined using CT. The associations between postoperative complication and the presence of PFC, and PFC index according to the location, were assessed. RESULTS The PFC group included 102 patients (69%). Postoperative pancreatic fistula (POPF) and organ/space surgical site infection (SSI) were more frequent in the PFC group (42% vs 9%, p < 0.001 and 29% vs 11%, p = 0.020, respectively). Additionally, the PFC index was larger in patients who developed POPF, organ/space SSI, or pseudoaneurysm (81 cm3 vs 19 cm3, p < 0.001; 75 cm3 vs 30 cm3, p = 0.001; and 185 cm3 vs 31 cm3, p < 0.001, respectively). Furthermore, superior and ventral PFCs were associated with pseudoaneurysm (11% vs 0%, p = 0.006 and 14% vs 1%, p = 0.002, respectively), whereas inferior and dorsal PFCs were associated with deep incisional SSI (9% vs 0%, p = 0.027 and 8% vs 1%, p = 0.034, respectively). CONCLUSION The PFC location during the early postoperative period is associated with postoperative complications. Our findings may help determine the optimal location of prophylactic drains.

Abstract
PURPOSE The β2-adrenergic receptor (β2AR) is highly expressed in various human cancers. The prognostic significance of its expression in patients with colorectal cancer (CRC) remains unclear. The aim of this study was to assess the prognostic role of β2AR expression in patients with surgically resected CRC. METHODS One hundred and forty-seven patients with surgically resected CRC were examined using immunohistochemistry. The expression of β2AR was assessed in the specimens of resected primary tumors. RESULTS β2AR was expressed in 52.3% of the patients' tumors. β2AR expression was significantly associated with T factor, N factor, and tumor cell proliferation (Ki-67 labeling index). Univariate analysis demonstrated that T factor, N factor, tumor stage, lymphatic permeation, vascular invasion, perineural invasion, β2AR expression, and Ki-67 labeling index were significant prognostic factors for worse disease-free survival (DFS); all but T factor were also significant predictors for worse overall survival (OS). Multivariate analysis confirmed that expression of β2AR was a significant prognostic marker for predicting worse DFS and OS. CONCLUSION β2AR expression was identified as a significant independent prognostic factor in patients with surgically resected CRC.

Abstract
BACKGROUND This study aimed to define an objective evidence-based threshold of high-volume hospitals (HVHs) for pancreatoduodenectomy (PD) using nationwide data systems. METHODS A total of 36,453 patients underwent PD in 1,499 hospitals from 2012 to 2015 were collected from the National Clinical Database in Japan. Restricted cubic spline model with risk adjustment was used for definition of an objective evidence-based threshold of HVHs. RESULTS The restricted cubic spline curve of 30-day and in-hospital mortality showed a continuous decrease with an increase in hospital volume and plateau phase of mortality was detected between approximately 30 and 50 PDs/year. On the basis of this curve, we defined hospitals ≥30 PDs/year as HVHs and ≤29 PDs/year as non-HVHs. We also sub-classified hospitals <5, 5-29, 30-49, and ≥50 PDs/year as low-volume, intermediate-volume, high-volume, and very high-volume hospitals using the spline curve. The odds ratio (OR) of risk-adjusted mortality decreased as hospital volume increased, with an OR of 0.34 for HVHs and 0.26 for very HVHs compared with low-volume hospitals. CONCLUSIONS We consider that this concept is applicable to other high-risk procedures for reducing mortality after these procedures, which could improve medical care and health services.

Abstract
BACKGROUND Total pancreatectomy is required to completely clear tumours that are locally advanced or located in the centre of the pancreas. However, reports describing clinical outcomes after total pancreatectomy are rare. The aim of this retrospective observational study was to assess clinical outcomes following total pancreatectomy using a nationwide registry and to create a risk model for severe postoperative complications. METHODS Patients who underwent total pancreatectomy from 2013 to 2017, and who were recorded in the Japan Society of Gastroenterological Surgery and Japanese Society of Hepato-Biliary-Pancreatic Surgery database, were included. Severe complications at 30 days were defined as those with a Clavien-Dindo grade III needing reoperation, or grade IV-V. Occurrence of severe complications was modelled using data from patients treated from 2013 to 2016, and the accuracy of the model tested among patients from 2017 using c-statistics and a calibration plot. RESULTS A total of 2167 patients undergoing total pancreatectomy were included. Postoperative 30-day and in-hospital mortality rates were 1·0 per cent (22 of 2167 patients) and 2·7 per cent (58 of 167) respectively, and severe complications developed in 6·0 per cent (131 of 2167). Factors showing a strong positive association with outcome in this risk model were the ASA performance status grade and combined arterial resection. In the test cohort, the c-statistic of the model was 0·70 (95 per cent c.i. 0·59 to 0·81). CONCLUSION The risk model may be used to predict severe complications after total pancreatectomy.

Long-term effects of an oral elemental nutritional supplement on post-gastrectomy body weight loss in gastric cancer patients (KSES002). Ann Gastroenterol Surg 2019; 3:648-656. [PMID: 31788653 PMCID: PMC6875942 DOI: 10.1002/ags3.12290] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 09/09/2019] [Accepted: 09/11/2019] [Indexed: 12/11/2022] Open
Abstract
AIM The present study aimed to evaluate the efficacy of short-term nutritional intervention with an oral elemental diet (ED; Elental; EA Pharma Co., Ltd, Tokyo, Japan) at 300 kcal/day for 6-8 weeks in the early post-gastrectomy period on postoperative long-term body weight loss (BWL). METHODS We analyzed consecutive patients who were randomly divided to receive the regular diet with or without ED. The control group received regular diet alone post-gastrectomy, whereas the ED group received 300 kcal ED plus regular diet for 6-8 weeks. Primary endpoint was percentage (%) BWL (body weight loss; body weight before surgery minus that at postoperative 1 year) by surgical type. Secondary endpoints included changes in nutrition-related blood parameters. RESULTS Of the patients in the original trial, 106 were eligible for efficacy analyses. %BWL at postoperative 1 year was significantly lower in the ED group than in the control group among patients who underwent total gastrectomy (TG) (n = 19 and n = 17, respectively; 9.66 ± 5.98% [95% confidence interval, CI: 6.77-12.54] vs 15.11 ± 6.78% [95% CI: 11.63-18.60], P = .015), but not in patients who underwent distal gastrectomy (n = 38 and n = 32, respectively; 5.81 ± 7.91% [95% CI: 3.21-8.41] vs 5.96 ± 6.20% [95% CI: 3.72-8.19], P = .933). In multivariate analysis, ED was the only factor affecting %BWL at postoperative 1 year among patients who underwent TG. CONCLUSIONS Daily nutritional intervention (300 kcal/day ED) for 6-8 weeks reduced %BWL not only at postoperative 6-8 weeks but also at 1 year in patients who underwent TG.

Utility of scoring systems combining the product of tumor number and size with liver function for predicting the prognosis of patients with hepatocellular carcinoma after hepatectomy. Oncol Lett 2019; 18:3903-3913. [PMID: 31516601 DOI: 10.3892/ol.2019.10688] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2019] [Accepted: 07/02/2019] [Indexed: 12/13/2022] Open
Abstract
Our previous study reported the effectiveness of the product of tumor number and size (NxS factor) as a predictor of the prognosis of patients with hepatocellular carcinoma (HCC) following hepatectomy. The aim of the present study was to validate the prognostic value of scoring systems based on the NxS factor for HCC. The records of 940 patients who underwent hepatectomy for HCC at Osaka University Graduate School of Medicine and Osaka International Cancer Institute were analyzed. The discriminatory abilities of the mathematical integrated model for tumor staging (MITS) score, which combines the NxS factor with liver function, and known prognostic systems, including the Japan Integrated Staging system, the Barcelona Clinic Liver Cancer, Cancer of the Liver Italian Program and the Tokyo system, were compared. Firstly, the present study demonstrated that a higher NxS factor was associated with decreased disease-free survival (DFS) and overall survival (OS) in patients with HCC (P<0.05). Subsequently, univariate analysis of DFS and OS curves revealed significant differences among all NxS factor and liver damage combinations (MITS-LD score; score 0 vs. score 1; score 1 vs. score 2; score 2 vs. score 3; all P<0.05) and all NxS factor and albumin-bilirubin (ALBI) score combinations (MITS-ALBI score; score 0 vs. score 1; score 1 vs. score 2; score 2 vs. score 3; all P<0.05). Furthermore, multivariate Cox proportional hazards model analysis demonstrated that there were significant differences in DFS [Hazard Ratio (HR); score 0 vs. score 1 (1.48); score 1 vs. score 2 (1.27); score 2 vs. score 3 (1.64); all P<0.05] and OS [HR; score 0 vs. score 1 (1.34); score 1 vs. score 2 (1.29); score 2 vs. score 3 (1.64); all P<0.05] among patients with different MITS-LD scores, and there were significant differences in DFS [HR; score 0 vs. score 1 (1.38); score 1 vs. score 2 (1.43); score 2 vs. score 3 (1.60); all P<0.05] among patients with different MITS-ALBI scores. The NxS factor may be a comprehensive measure of tumor burden for predicting the prognosis of patients with HCC following liver resection, and MITS scores could be an improved scoring system for predicting the prognosis of patients with HCC after hepatectomy.

Abstract
PURPOSE We evaluated the recent incidence of surgery and the changing surgery trends for ulcerative colitis (UC) in Japan due to the increasing use of anti-tumor necrosis factor (TNF) agents. METHODS A questionnaire survey was performed to assess the number of surgeries, surgical indications, surgical timing, and immunosuppressive treatments before surgery between 2007 and 2017. RESULTS A total of 3801 surgical cases were reported over 11 years. The prevalence of UC surgery decreased over the period studied. The rate of prednisolone (PSL) use did not change. The prevalence of both calcineurin inhibitors (CNIs) and anti-TNF agents increased during the period studied (p < 0.01). The prevalence of urgent/emergent surgery did not change. The most distinctive change in surgical indications was the increase in cancer/dysplasia (CAC), the prevalence of which increased from 20.2% in 2007 to 34.8%. CONCLUSION The prevalence of UC surgery seems to be decreasing according to the increasing rate of anti-TNF agent and CNI administration. However, the indication of CAC significantly increased. Further research should evaluate whether or not long-term remission maintained with several agents can lead to increasing CAC.

Abstract
BACKGROUND The Japanese National Clinical Database (NCD) is a large-scale, nationwide, web-based data entry system that is linked to the surgical board certification system and covers almost all surgical cases carried out in Japan. AIM To evaluate outcomes according to the gastroenterological section of the NCD. METHODS The 115 surgical procedures stipulated by the "Training Curriculum for Board-Certified Surgeons in Gastroenterology" were registered from 2011 to 2017. The number of surgeries, preoperative comorbidities, and short-term outcomes were compared between registration periods. RESULTS In total, 3 818 414 cases have been registered. More than 70% of all surgeries were carried out at certified institutions. The annual number of cases has been increasing year after year, and the aged population has also been increasing. Although the rates of preoperative comorbidities and postoperative complications have been increasing, the postoperative mortality rate has remained relatively low; in 2017, the 30-day mortality rate was 1.0% among those who underwent esophagectomy, 0.7% among those who underwent distal gastrectomy, 1.1% among those who underwent total gastrectomy, 1.3% among those who underwent right hemicolectomy, 0.5% among those who underwent low anterior resection, 1.3% among those who underwent hepatectomy, and 1.3% among those who underwent pancreaticoduodenectomy. The annual rate of endoscopic surgery dramatically increased over 7 years between 2011 and 2017, especially for low anterior resection (29.5%-62.6%) and esophagectomy (31.0%-56.1%). CONCLUSION This database is expected to ensure the quality of the board-certification system and surgical outcomes in gastroenterological surgery.

Ann Gastroenterol Surg 2019; 3:343-351. [PMID: 31346572 PMCID: PMC6635687 DOI: 10.1002/ags3.12250] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 03/10/2019] [Accepted: 03/21/2019] [Indexed: 01/15/2023] Open
Abstract
The Japanese Society of Gastroenterological Surgery (JSGS) and the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) have collaboratively developed several clinical projects since 2011 using two nationwide clinical registries with the goal of achieving further improvement of surgical quality in both countries. In this review, the historical viewpoints and the collaboration between JSGS and ACS and their use of nationwide registries [National Clinical Database (NCD) and NSQIP] for research are reviewed. We have carried out a joint project, the 30-day Mortality Risk Model Study and, currently, we are working on several joint projects such as the Morbidity-Mortality Study, Japan-USA Calibration Study, Geriatric Study, and Safety Culture Study as well as Auditing in JSGS/NCD with reference to the NSQIP method. These joint projects will continue to provide us with important information and data to drive improvements in surgical care in both countries. This will also help us to identify any unknown weaknesses in the health-care systems of the USA and Japan.

Abstract
BACKGROUND The current status of site-specific cancer registry has not been elucidated, but sufficient system is found in some societies. The purpose of this study was to clear the present condition of site-specific cancer registries in Japan and to suggest for the improvement. METHODS The questionnaire was conducted by the study group of the Ministry of Health, Labor, and Welfare. It consisted of 38 questions, conflicts of interest, clinical research method, informed consent and funding for registry. We distributed this questionnaire to 28 academic societies, which had published the clinical practice guideline(s) assessed under Medical Information Network Distribution Service (MINDS). RESULTS The concept of the importance in assessment for medical quality by the data of the site-specific cancer registry was in good consensus. But the number of the society with the mature registry was limited. The whole-year registry with the scientific researches in the National Clinical Database (NCD) and in the Translational Research Informatics Center (TRI) might seem to be in success, because assured enhancement may be estimated. Now, academic societies have the structural factors, i.e., the financial limitation in the registry maintenance and the data analysis, and in the difficulty of employment of the researchers with skill and talent. CONCLUSIONS To manage the site-specific cancer registry effectively, the scientific registry system will be essentially important. Each academic society had much experienced highly qualified clinical researches in past. Accordingly, the scientific suggestion and co-operation should be of great importance for the improvement.

Toh Y, Yamamoto H, Miyata H, Gotoh M, Watanabe M, Matsubara H, Kakeji Y, Seto Y. Significance of the board-certified surgeon systems and clinical practice guideline adherence to surgical treatment of esophageal cancer in Japan: a questionnaire survey of departments registered in the National Clinical Database. Esophagus 2019; 16:362-370. [PMID: 30980202 PMCID: PMC6744385 DOI: 10.1007/s10388-019-00672-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2018] [Accepted: 04/07/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND It remains unknown how much institutional medical structure and process of implementation of clinical practice guidelines for esophageal cancers can improve quality of surgical outcome in Japan. METHODS A web-based questionnaire survey was performed for departments registered in the National Clinical Database in Japan from October 2014 to January 2015. Quality indicators (QIs) including structure and process indicators (clinical practice guideline adherence) were evaluated on the risk-adjusted odds ratio for operative mortality (AOR) of the patients using registered cases in the database who underwent esophagectomy and reconstruction in 2013 and 2014. RESULTS Among 916 departments which registered at least one esophagectomy case during the study period, 454 departments (49.6%) responded to the questionnaire. Analyses of 6661 cases revealed that two structure QIs (certification of training hospitals by Japan Esophageal Society and presence of board-certified esophageal surgeons) were associated with significantly lower AOR (p < 0.001 and p = 0.005, respectively). One highly recommended process QI regarding preoperative chemotherapy had strong tendency to associate with lower AOR (p = 0.053). In two process QIs, the answer "performed at the doctor's discretion" showed a significant negative impact on prognosis, suggesting importance of institutional uniformity. CONCLUSIONS The medical institutional structure of board-certified training sites for esophageal surgeons and of participation of board-certified esophageal surgeons improves surgical outcome in Japan. Establishment of appropriate QIs and their uniform implementation would be crucial for future quality improvement of medical care in esophagectomy.

Perioperative and prognostic implication of albumin-bilirubin-TNM score in Child-Pugh class A hepatocellular carcinoma. Ann Gastroenterol Surg 2019; 3:65-74. [PMID: 30697612 PMCID: PMC6345730 DOI: 10.1002/ags3.12212] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Revised: 06/22/2018] [Accepted: 08/26/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND AND AIM A reliable classification for predicting postoperative prognosis and perioperative risk of hepatocellular carcinoma (HCC) patients is required to make a precise decision for HCC treatment. In the present study, we assessed the perioperative and prognostic importance of indocyanine green (ICG) testing, tumor-node-metastasis (TNM) stage, albumin-bilirubin (ALBI) grade, and ALBI-TNM (ALBI-T) score using consecutive resected HCC cases. METHODS Between 1998 and 2011, 273 consecutive patients who underwent primary and curative hepatectomy for HCC were identified. Among these 273 cases, 235 Child-Pugh class A patients were enrolled in the present study. RESULTS Correlation analysis showed that the value of linear predictor for ALBI grade was significantly correlated with ICG 15-minute retention rates (r = 0.51, P < 0.0001). Survival analysis for both recurrence-free survival (RFS) and overall survival (OS) showed there were significant differences between the two groups stratified by stage or ALBI-T score (stage, RFS: P = 0.01, OS: P = 0.003; ALBI-T, RFS: P < 0.0001, OS: P < 0.0001). In addition, Cox proportional hazard model identified ALBI-T score was a significant predictor for both RFS and OS (RFS, P = 0.001; OS, P = 0.004). Furthermore, ALBI-T score could predict perioperative risk in hepatectomy such as longer operation time and excessive intraoperative blood loss. CONCLUSIONS This study showed a robust association of ALBI-T score with postoperative HCC patient survival and perioperative risk in hepatectomy. ALBI-T score can be used as a simple and powerful tool for assessing HCC patients with further study.
