Laparoscopic gastrectomy with extraperigastric lymphadenectomy for early gastric cancer has never been performed because of technical difficulties attributable to the lack of appropriate techniques, the high cost of laparoscopic instruments, and the need for numerous disposable stapling devices. In order to solve these problems, we have designed a method of laparoscopic minilaparotomy using an abdominal wall-lifting method, and a patient with early gastric cancer (depth of submucosa) underwent by this laparoscopic minilaparotomy distal gastrectomy with extraperigastric lymphadenectomy. During his postoperative recovery, the patient requested no narcotic analgesic, and was discharged on postoperative day 14.
Background: Patient safety culture is defined as a product of individual and group values, attitudes, perceptions, competencies, and patterns of behavior that determine the commitment to, and the style and proficiency of, an organization's health and safety management. Factors influencing healthcare workers' working environment such as working hours, the number of night shifts, and the number of days off may be associated with patient safety culture, and the association pattern may differ by profession. This study aimed to examine the relationship between patient safety culture and working environment. Methods: Questionnaire surveys were conducted in 2015 and 2016. The first survey was conducted in hospitals in Japan to investigate their patient safety management system and activities and intention to participate in the second survey. The second survey was conducted in 40 hospitals; 100 healthcare workers from each hospital answered a questionnaire that was the Japanese version of the Hospital Survey on Patient Safety Culture for measuring patient safety culture. The relationship of patient safety culture with working hours in a week, the number of night shifts in a month, and the number of days off in a month was analyzed. Results: Response rates for the first and second surveys were 22.4% (731/3270) and 94.2% (3768/4000), respectively. Long working hours, numerous night shifts, and few days off were associated with low patient safety culture. Despite adjusting the working hours, the number of event reports increased with an increase in the number of night shifts. Physicians worked longer and had fewer days off than nurses. However, physicians had fewer composites of patient safety culture score related to working hours, the number of night shifts, and the number of days off than nurses.
[Purpose] To study the brain function during a dual task (cycling exercise and cognitive
training) via functional near-infrared spectroscopy in young males. [Participants and
Methods] Twenty Japanese young male participants were divided into intervention and
control groups by simple randomization (n=10 per group). In the intervention group,
participants were given a cognitive program training and cycling exercise (dual task). The
control group was given the cognitive program training (single task) only. The cognitive
program training consisted of a warm up, followed by 2 minutes of rock-paper-scissors, 2
minutes of numeric memory, 2 minutes of color matching, 2 minutes of calculations, and a
cool down. Brain function tests were performed individually throughout the programs by
functional near-infrared spectroscopy. [Results] The oxyhemoglobin levels significantly
increased in the frontal lobe of the intervention and control groups after program
completion compared to before. And the oxyhemoglobin levels of the intervention group also
significantly increased more than control group in the prefrontal cortex and motor area.
[Conclusion] This program used by Cognibike was also effective for improving hemoglobin
oxygen levels at the frontal lobe in young males.
BackgroundSince the late 1990s, patient safety has been an important policy issue in developed countries. To evaluate the effectiveness of the activities of patient safety, it is necessary to quantitatively assess the incidence of adverse events by types of failure mode using tangible data. The purpose of this study is to calculate patient safety indicators (PSIs) using the Japanese Diagnosis Procedure Combination/per-diem payment system (DPC/PDPS) reimbursement data and to elucidate the relationship between perioperative PSIs and hospital surgical volume.MethodsDPC/PDPS data of the Medi-Target project managed by the All Japan Hospital Association were used. An observational study was conducted where PSIs were calculated using an algorithm proposed by the US Agency for Healthcare Research and Quality. We analyzed data of 1,383,872 patients from 188 hospitals who were discharged from January 2008 to December 2010.ResultsAmong 20 provider level PSIs, four PSIs (three perioperative PSIs and decubitus ulcer) and mortality rates of postoperative patients were related to surgical volume. Low-volume hospitals (less than 33rd percentiles surgical volume per month) had higher mortality rates (5.7%, 95% confidence interval (CI), 3.9% to 7.4%) than mid- (2.9%, 95% CI, 2.6% to 3.3%) or high-volume hospitals (2.7%, 95% CI, 2.5% to 2.9%). Low-volume hospitals had more deaths among surgical inpatients with serious treatable complications (38.5%, 95% CI, 33.7% to 43.2%) than high-volume hospitals (21.4%, 95% CI, 19.0% to 23.9%). Also Low-volume hospitals had lower proportion of difficult surgeries (54.9%, 95% CI, 50.1% to 59.8%) compared with high-volume hospitals (63.4%, 95% CI, 62.3% to 64.6%). In low-volume hospitals, limited experience may have led to insufficient care for postoperative complications.ConclusionsWe demonstrated that PSIs can be calculated using DPC/PDPS data and perioperative PSIs were related to hospital surgical volume. Further investigations focusing on identifying risk factors for poor PSIs and effective support to these hospitals are needed.
Carcinoma of the main hepatic duct junction tends to invade extensively the bile ducts and hepatic parenchyma, although dissemination is rarely seen. Therefore, extensive resection of the bile ducts combined with hepatic resection is the procedure of choice for treating this disease. From January 1973 to January 1987, 23 of 41 patients underwent resection, giving a resectability rate of 56%. One patient died postoperatively, yielding an operative mortality rate of 4.3%. The 5-year actuarial survival rate is 29.8%. Three patients are now alive and well 6 years and 9 months, 5 years and 10 months, and 5 years and 5 months after the operation. One additional patient who underwent resection in an affiliated hospital has done well for 8 years and 8 months. The results from these four patients treated by curative resection support a strategy featuring curative resection with aggressive surgery.
Laparoscopic distal gastrectomy is still technically difficult because of the lack of appropriate techniques, the expensive laparoscopic instruments, and the use of numerous disposable stapling devices. In an attempt to solve these problems, we have designed a method of laparoscopic and minilaparotomy Billroth I gastrectomy using an abdominal wall-lifting method.
