Abstract
BACKGROUND In the global aging, the coronavirus disease 2019 (COVID-19) pandemic may have affected the place of death (PoD) in Japan, where hospital deaths have dominated for decades. We analyzed the PoD trends before and during the COVID-19 pandemic in Japan. METHODS This nationwide observational study used vital statistics based on death certificates from Japan between 1951 and 2021. The proportion of PoD; deaths at home, hospitals, and nursing homes; and annual percentage change (APC) were estimated using joinpoint regression analysis. Analyses were stratified by age groups and causes of death. RESULTS After 2019, home deaths exhibited upward trends, while hospital death turned into downward trends. By age, no significant trend change was seen in the 0-19 age group, while hospital deaths decreased in the 20-64 age group in 2019. The trend change in home death in the ≥65 age group significantly increased since 2019 with an APC of 12.3% (95% confidence interval [CI]: 9.0 to 15.7), while their hospital death trends decreased by -4.0% (95% CI: -4.9 to -3.1) in 2019-2021. By cause of death, home death due to cancer and the old age increased since 2019 with an APC of 29.3% (95% CI: 25.4 to 33.2) and 8.8% (95% CI: 5.5 to 12.2), respectively. CONCLUSION PoD has shifted from hospital to home during the COVID-19 pandemic in Japan. The majority of whom were older population with cancer or old age.

Abstract
CONTEXT The perspective toward hypoactive delirium in the last days of life could be different among physicians. OBJECTIVES To clarify the attitudes, beliefs, and opinions of palliative care physicians and liaison psychiatrists toward hypoactive delirium in the last days of life and to explore the association among these factors. METHODS A nationwide cross-sectional questionnaire survey was conducted among 1667 physicians who were either certified palliative care specialists or liaison psychiatrists. Physicians' agreement with the appropriateness of pharmacological management (e.g., antipsychotics) (one item), their beliefs (11 items), and their opinions (four items) were measured. RESULTS 787 (47%) physicians responded. 481 (62%) agreed to use of medications for hypoactive delirium in the last days of life, whereas 296 (38.1%) disagreed. More than 95% agreed with "hypoactive delirium at the end of life can be considered as a part of natural dying process." Multivariate analysis identified two belief subscales of "hypoactive delirium at the end of life is a natural dying process" and "antipsychotics are futile and harmful in managing hypoactive delirium" had a significant negative correlation with the use of medications. On the other hand, one belief subscale of "hypoactive delirium can be distressing even if patients' consciousness is impaired" had significant positive correlations with the use of medications. CONCLUSION Pharmacological management of hypoactive delirium in the last days of life differs depending on physicians' beliefs. Future research is needed to clarify the efficacy and safety of pharmacological management of hypoactive delirium.

Abstract
OBJECTIVE The objective of this survey was to identify areas where doctors have divergent practices in pharmacological treatment for hyperactive delirium in terminally ill patients with cancer. METHODS We conducted a survey of Japanese palliative care physicians and liaison psychiatrists. Inquiries were made regarding: (i) choice of drug class in the first-line treatment, (ii) administration methods of the first-line antipsychotic treatment, (iii) starting dose of antipsychotics in the first line treatment and maximum dose of antipsychotics in refractory delirium, and (iv) choice of treatment when the first-line haloperidol treatment failed. Respondents used a five-point Likert scale. RESULTS Regarding choice of drug class in the first-line treatment, more doctors reported that they 'frequently' or 'very frequently' use antipsychotics only than antipsychotics and benzodiazepine (oral: 73.4 vs. 12.2%; injection: 61.3 vs. 11.6%, respectively). Regarding administration methods of the first-line antipsychotic treatment, the percentage of doctors who reported that they used antipsychotics as needed and around the clock were 55.4 and 68.8% (oral), 49.2 and 45.4% (injection), respectively. There were different opinions on the maximum dose of antipsychotics in refractory delirium. Regarding the choice of treatment when the first-line haloperidol treatment failed, the percentage of doctors who reported that they increased the dose of haloperidol, used haloperidol and benzodiazepines, and switched to chlorpromazine were 47.0, 32.1 and 16.4%, respectively. CONCLUSIONS Doctors have divergent practices in administration methods of the first-line antipsychotic treatment, maximum dose of antipsychotics, and choice of treatment when the first-line haloperidol treatment failed. Further studies are needed to determine the optimal treatment.

Abstract
Peptic esophagitis can occur as a complication of laparoscopic Heller-Dor surgery (LHD) among patients with esophageal achalasia. The goal of this study was to identify the characteristics of patients who have developed peptic esophagitis following LHD surgery along with the risk factors associated with the occurrence of peptic esophagitis. Among the 447 cases consisting of esophageal achalasia patients who underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not peptic esophagitis occurred following surgery. We also attempted to use univariate and multivariate analyses to identify the risk factors for peptic esophagitis occurring following surgery. Esophagitis following surgery was confirmed in 67 cases (15.0%). With respect to the patient backgrounds for cases in which peptic esophagitis had occurred, a significantly higher number were male patients, with a significantly high occurrence of mucosal perforation during surgery in terms of surgical outcomes, along with a high occurrence of esophageal hiatal hernias in terms of postoperative course (P = 0.045, 0.041, and 0.022, respectively). However, there were no significant differences in terms of age, BMI, disease duration, preoperative symptoms, esophageal manometric findings, esophageal barium findings, and esophageal clearance. A multivariate analysis indicated independent risk factors for the occurrence of peptic esophagitis following LHD as being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias. Peptic esophagitis occurred following LHD in 15% of cases. Independent risk factors for the occurrence of peptic esophagitis following LHD included being male, the occurrence of mucosal perforation during surgery, and the occurrence of esophageal hiatal hernias following surgery.

Abstract
Major cardiology societies’ guidelines support integrating palliative care into heart failure (HF) care. This study aimed to identify the effectiveness of the HEart failure Palliative care Training program for comprehensive care providers (HEPT), a physician education program on primary palliative care in HF. We performed a pre- and post-test survey to evaluate HEPT outcomes. Physician-reported practices, difficulties and knowledge were evaluated using the Palliative Care Self-Reported Practices Scale in HF (PCPS-HF), Palliative Care Difficulties Scale in HF (PCDS-HF), and Palliative care knowledge Test in HF (PT-HF), respectively. Structural equation models (SEM) were used to estimate path coefficients for PCPS-HF, PCDS-HF, and PT-HF. A total of 207 physicians participated in the HEPT between February 2018 and July 2019, and 148 questionnaires were ultimately analyzed. The total PCPS-HF, PCDS-HF, and PT-HF scores were significantly improved 6 months after HEPT completion (61.1 vs 67.7, p<0.001, 54.9 vs 45.1, p<0.001, and 20.8 vs 25.7, p<0.001, respectively). SEM analysis showed that for pre-post difference (Dif) PCPS-HF, “clinical experience of more than 14 years” and pre-test score had significant negative effects (-2.31, p = 0.048, 0.52, p<0.001, respectively). For Dif PCDS-HF, ≥ “28 years old or older” had a significant positive direct effect (13.63, p<0.001), although the pre-test score had a negative direct effect (-0.56, p<0.001). For PT-HF, “involvement in more than 50 HF patients’ treatment in the past year” showed a positive direct effect (0.72, p = 0.046), although the pre-test score showed a negative effect (-0.78, p<0.001). Physicians who completed the HEPT showed significant improvements in practice, difficulty, and knowledge scales in HF palliative care.

Abstract
BACKGROUND AND OBJECTIVES The Lyon Consensus was conducted in 2017, leading to a revision of the diagnostic criteria of GERD. Conclusive GERD was defined as cases in which the distal esophageal acid exposure time (AET) is greater than 6% and there exists either peptic esophagitis, constriction, or long-segment Barrett's mucosa with a Los Angeles classification of grade C or D. Borderline GERD is defined as cases in which AET is between 4 and 6% and there exists peptic esophagitis with a Los Angeles classification of either grade A or B. All other cases were defined as Inconclusive GERD. We conducted a retrospective investigation of the treatment results of laparoscopic fundoplication (LF) for GERD according to the Lyon Consensus and evaluated whether or not it is an effective treatment predictor. MATERIALS AND METHODS From among the cases of primary LF conducted on patients with GERD-related illnesses at our university hospital from June 2008 to March 2020, the subjects included 215 individuals who underwent upper gastrointestinal endoscopy and 24 h multichannel intraluminal impedance pH (MII-pH) testing prior to surgery. We compared the pathophysiology of the Conclusive GERD Group (Group A), Borderline GERD Group (Group B), and Inconclusive GERD Group (Group C), and then investigated the treatment results of each group. We used AFP classification for pathophysiological evaluation. For the acid reflux evaluation, we conducted MII-pH measurements using Sleuth, manufactured by Sandhill. The postoperative evaluation period was set to 3 months following surgery. The data are expressed using median values, with a statistical significance defined as p < 0.05 using the Kruskal-Wallis, Mann-Whitney, Wilcoxon signed-rank, and Chi-squared tests. RESULTS Group A: 92 cases (43%, male 69 cases, age 57), Group B: 48 cases (22%, male 20 cases, age 52), and Group C: 75 cases (35%, male 69 cases, age 57). Regarding the patient backgrounds, while there were no significant differences in terms of gender or disease duration, those in Group A were significantly older than the other two groups, and there was a significant difference in Body Mass Index (BMI) between Group A and Group C. The results of each factor were: A factor (1 vs.1 vs. 1, p < 0.001), F factor (2 vs. 0 vs. 0, p < 0.001), and P factor (2 vs. 1 vs. 0, p < 0.001), with AET of 10.0 vs. 2.9 vs. 0.6, p < 0.001, and the disease had progressed more in Group A. There were also no differences in terms of surgical methods, hemorrhage volume, and intraoperative/postoperative complications; however, the use of mesh was higher and surgery duration was longer in Group A. There were obvious improvements in the A, F, and P factors and AET of each group following surgery (other than F and P of Group C, p < 0.001). The rate of recurrence was 15% in Group A, 8% in Group B, and 6% in Group C. It tended to be higher in Group A, but this was not statistically significant. CONCLUSION The classification of GERD pathophysiology based on the Lyon Consensus is satisfactory, with no significant differences in the rate of effect of LF. The Lyon Consensus is effective for ascertaining the severity and pathophysiology of GERD; however, we were unable to forecast the treatment results of LF.

Abstract
BACKGROUND It is anticipated that surgical treatment for gastro-esophageal reflux disease (GERD) in the elderly will increase. This time, using propensity score matching, we examined the results of laparoscopic fundoplication (LF) for GERD-related diseases in the elderly. METHODS Of 302 cases which underwent initial LF for GERD-related diseases during the period from June 2008 to February 2019, we classified them into elderly (65 years of age or older) and non-elderly groups (64 years of age or younger). 57 cases each were extracted upon performing propensity score matching regarding five factors including: gender; body mass index; esophageal hiatal hernia; extent of reflux esophagitis; and the use of mesh. RESULTS With regard to the preoperative disease status, the pH < 4 holding time was indicated as 2.8% (0.5-10.7%) in the elderly group and 3.4% (0.6-8.0%) in the non-elderly group, with no difference in terms of the illness period as well (p = 0.889 and p = 0.263, respectively). Although there was no difference in terms of the operative time (155 vs. 139 min, p = 0.092) and estimated blood loss (both ≒ 0 ml, p = 0.298), postoperative hospital stay was prolonged in the elderly group [7 (7-9) vs. 7 (7-7), p = 0.007]. On the other hand, esophageal hiatal hernia, reflux esophagitis, and acid reflux time in the esophagus were all improved following surgery in both groups (p < 0.001 in both groups). CONCLUSION The treatment results of LF for GERD-related diseases in the elderly were as good as those in the non-elderly, indicating possible safe implementation.

Abstract
BACKGROUND It is common knowledge that esophageal achalasia patients have a high risk of developing esophageal carcinoma. The present study assessed the characteristics of esophageal carcinoma patients following laparoscopic Heller-Dor surgery (LHD) for esophageal achalasia. METHOD Among 622 cases which were esophageal achalasia patients and underwent LHD as the primary surgery, we compared the patient background, pathophysiology, symptoms, and surgical outcomes according to whether or not esophageal carcinoma occurred following surgery. RESULTS Six cases (0.96%) of postoperative esophageal carcinoma were confirmed. The characteristics of the cases in which esophageal carcinoma occurred were older age, longer disease duration (p = 0.0362 and 0.0028, respectively), decreased sphincter pressure of the lower esophagus, a high rate of sigmoid esophagus, and a long esophagus lateral diameter (p = 0.0214, 0.001, and 0.0416, respectively). Moreover, no differences in surgical outcomes were confirmed and there were no differences in symptoms from before and following surgery. CONCLUSION The characteristics of esophageal carcinoma patients with achalasia following laparoscopic myotomy were an older age, longer disease duration, and greater progression of disease pathophysiology.

Abstract
INTRODUCTION Abdominal pain and distention are common in ovarian tumours. When the ovarian tumour grows too large, the tumour can cause these symptoms. Percutaneous drainage from ovarian tumours, which can alleviate symptoms, is traditionally discouraged for its potential risk of peritoneal tumour seeding. CASE A 73-year-old woman with a multilocular ovarian tumour reporting abdominal fullness and pain was referred to the palliative care outpatient department. The multilocular tumour occupied most of the intra-abdominal space, which was determined to cause her symptoms. To alleviate her symptoms, we performed intermittent percutaneous drainage for 1.5 years. A clinical autopsy revealed the tumour was an ovarian mucinous carcinoma. Despite iterative tumour drainage, we observed no feature of peritoneal dissemination. CONCLUSION Intermittent percutaneous drainage of ovarian tumours could reduce tumour-related abdominal symptoms without pathological evidence of peritoneal dissemination. This procedure can be a new palliative treatment option for ovarian tumour-related abdominal symptoms.

Abstract
Background: Although many Japanese patients wish to take a bath in their last days, the safety of bathing for patients with a prognosis of a few days is not known. Objective: To examine whether taking a bath affects the survival of advanced cancer patients with prognoses of a few days. Design: A single-center prospective cohort study. Setting/Subject: Advanced cancer patients in their last days of life in a palliative care unit of a Japanese hospital. We compared patients who took baths with those who did not. The primary endpoint was 24-hour survival rate. Result: Among 110 patients eligible for this prospective study, 89 (72%) met the inclusion criteria. Forty-eight patients (43%, 223 person-days) were eligible for analysis. A total of 28 patient-days were classified into the bathing group, and 192 patient-days were classified into the nonbathing group. After propensity score matching, the 24-hour death rate was 10.7% in the bathing group and 8.0% in the nonbathing group, respectively (mean difference 2.8% with 95% confidence interval of −11.2% to 16.8%, p = 0.65). Conclusion: Taking a bath does not appear to bear a significant association with shortening of life among advanced cancer patients in their last days of life.

Abstract
INTRODUCTION Laparoscopic surgery is considered safe and effective for a gastric submucosal tumors, and reduced-port surgery (RPS) is being increasingly performed to treat these tumors. Herein, we present laparoscopic RPS with the cowboy technique for the removal of gastric submucosal tumors. MATERIALS AND SURGICAL TECHNIQUE A single-port access device was inserted at the naval (three 5-mm trocars), and a 5-mm trocar was inserted in the left lateral abdominal wall. A ligature was placed at the neck of the tumor, the loop was then tightened, and the knot was finally secured-a process referred to as the cowboy technique. This technique enables complete surgical excision and can be used for exophytic submucosal tumors of the stomach. Four patients underwent RPS with this technique, and the outcomes were good. DISCUSSION Our cowboy technique enables the safe full-thickness excision of gastric submucosal tumors with exophytic growth and is very useful in performing RPS.

Abstract
Background: Recently, in pursuit of minimal invasion, needlescopic surgery (NS) using forceps thinner than the previous standard has garnered attention as a surgical approach to various diseases. Objective: We compared the outcomes of NS for gastroesophageal reflux disease (GERD)-related diseases with the conventional method using propensity score-matched analysis. Subjects and Methods: Among 205 of 328 cases who underwent laparoscopic fundoplication for the first time from June 2008 to December 2019, excluding 115 cases using mesh and 8 cases undergoing reduced port surgery, 25 subjects in the NS group and 25 subjects in the conventional group were extracted upon propensity score matching for six factors: age, gender, body mass index, degree of esophageal hiatal hernia, duration of intraesophageal acid reflux, and severity of reflux esophagitis. Results: The NS group used the Toupet method, whereas the conventional group used the Nissen method for 2 cases and the Toupet method for 23 cases. There were no significant differences between them (P = .490). Although the operative time (143 versus 112 minutes, P = .038) was longer in the NS group, there were no differences in the bleeding volume (nearly equal at 0 mL in both groups), laparotomy conversion rate, intraoperative complications, and postoperative complications (P = .588, P = 1.000, P = 1.000, P = 1.000, respectively). There was also no significant difference in recurrence: 2 cases in the conventional group (8%) and 1 case in the NS group (4%) (P = 1.000). Moreover, the degree of esophageal hiatal hernia, the severity of reflux esophagitis, and the duration of intraesophageal acid reflux all improved after the surgery in both groups (NS group: P = .001, P < .001, P = .002; conventional group: P = .007, P < .001, P = .003). Conclusions: The short-term outcomes of NS for GERD-related diseases were good, with a longer operative time but no difference in terms of safety or outcomes compared with the conventional method. This study was approved by the Institutional Review Board of the Jikei University School of Medicine [30-238 (9259)].

Abstract
BACKGROUND AND AIM The relationship between gastroesophageal reflux disease (GERD) and sleep disturbance has recently been pointed out and is garnering substantial attention. Although there are reports that point out the effectiveness of medical treatment for sleep disturbance associated with GERD, examinations of the pathological condition, including reflux during sleep, are inadequate. In the present study, we evaluated the recumbent reflux in patients with GERD and sleep disturbance using multichannel intraluminal impedance pH (MII-pH), and attempted to suppress recumbent reflux by surgical treatment to examine the pathophysiology of patients with GERD and sleep disturbance. MATERIALS AND METHODS Of the 47 patients with GERD-related diseases in whom laparoscopic fundoplication was performed at The Jikei University Hospital from January 2016 to June 2017, 31 patients (average age: 55.9 ± 13.8 years, male in 25), excluding 9 with surgical indications only for esophageal hiatal hernia and 7 without postoperative evaluation, were the subjects of this study. All surgical procedures were performed by the Toupet method. We used the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep disturbance, setting 5.5 as the cut-off value, based on the report by Doi et al., with any conditions beyond this value deemed sleep disturbance. The evaluation of gastroesophageal reflux was carried based on the MII-pH using the Sleuth, manufactured by Sandhill Corporation, with an automatic analysis carried out by computer. Furthermore, recumbent abnormal reflux was defined as recumbent all reflux (times) > 7. All evaluations were performed preoperatively and at 3 months after the operation. The data were expressed in medians and interquartile ranges, with p < 0.05 defined as statistically significant by the Mann-Whitney, Wilcoxon, or Chi-squared test. RESULTS Although sleep disturbance was found in 19 cases (61%), 8 (42%) of which were actually confirmed as nighttime abnormal reflux, of whom 5 cases (63%) showed significant improvement in their sleep disturbance following the operation, with a PSQI score of lower than 5.5. Among these 5 cases, postoperative recumbent abnormal reflux was also significantly reduced as compared with the preoperative condition (17 vs. 2 times/day, p = 0.042). Furthermore, sleep disturbance improved and recumbent abnormal reflux also decreased in two cases, with sleep disturbance improved by controlling the nighttime reflux via surgery in a total of 7 cases (87.5%). Although the PSQI score was as high as 14 points before and after the operation in one case, the rate of recumbent abnormal reflux was remarkably reduced, with sleep disturbance and recumbent reflux considered irrelevant. Furthermore, regarding the frequency of recumbent acid/non-acid reflux, while non-acid reflux was significantly more frequent in the patients with recumbent reflux complications (9 vs. 1 time/day, p < 0.001), there was no marked difference in the frequency of acid reflux. CONCLUSIONS Among cases with GERD and sleep disturbance, approximately one-third of them showed findings suggestive of the involvement of recumbent reflux in sleep disturbance, with reflux characterized by non-acid reflux.

Abstract
BACKGROUND We encountered a case of marginal ulcer in the jejunum after distal gastrectomy with jejunal pouch interposition. However, it has not been reported and not confirmed the treatment. We chose truncal vagotomy, considering reduced morbidity and postoperative complications. CASE PRESENTATION A case was a 69-year-old woman who was admitted to our hospital with melena. She had received curative distal gastrectomy with a 15-cm jejunal pouch reconstruction for early gastric cancer. Marginal ulcer in the jejunal pouch was detected by upper gastrointestinal endoscopy. She was given medication; however, she repeated hospitalization for melena and abdominal pain. Therefore, we decided to perform surgery, and truncal vagotomy was performed. The patient's postoperative course was uneventful and was discharged on the 22nd postoperative day. Symptoms such as abdominal pain and melena were improved after truncal vagotomy. CONCLUSION We presented a case with a complicated peptic ulcer after distal gastrectomy with reconstruction by jejunal pouch interposition, which was successfully treated by truncal vagotomy, a surgical acid-reducing procedure which does not require resection of remnant stomach.

Abstract
The energy spreads of ion beams generated from a penning ionization gauge-type ion source with electromagnets were measured using a parallel electrostatic analyzer. The ion source was developed to be installed in a mega-electron volt (MeV) compact ion microbeam system. A gaseous ion beam of expectedly high brightness and narrow energy spread was generated from the ion source to form a microbeam. To produce such an ion beam, a high-density plasma with a small volume was generated using a strong magnetic field in the ion source. The beam energy spread width was of particular importance because it forms an ion microbeam by reducing the chromatic aberration at a focusing lens. In this report, the energy spread was investigated by changing the parameters of the ion source, e.g., extraction voltage, excitation current of electromagnets, vacuum, and anode voltage. The investigation showed that spread widths are influenced by the extraction voltage, vacuum, and anode voltage. The minimum width of ∼5.0 ± 0.1 eV was obtained at a beam energy of 200 eV. This value is acceptable for the MeV compact ion microbeam system.

Abstract
BACKGROUND Chest pain reduces the quality of life of patients with achalasia. Although laparoscopic Heller-Dor surgery (LHD) is a standard surgical treatment for achalasia, its therapeutic efficacy for chest pain is not clear. The present study evaluated the therapeutic efficacy of LHD for chest pain and tried to identify factors associated with the relief of chest pain. METHODS The study included 244 patients with preoperative chest pain who underwent LHD as the first surgical intervention. The questionnaire-based symptom frequency score was multiplied by the severity score, and the calculated metric was defined as the symptom score. The study population was stratified, by the change in the chest pain symptom score, into Complete Remission (CR), Partial Remission (PR), and No Remission (NR) groups, which were compared for patient background and surgical outcome. Multivariate analysis was also performed to determine factors associated with the relief of chest pain. RESULTS As for preoperative clinicopathological conditions, the CR subgroup was older (p = 0.0169) with fewer previous balloon dilatations (p = 0.009). Although no difference was detected in the surgical outcome, the NR group had higher postoperative symptom scores for both difficulty in swallowing and vomiting and a lower score for patient satisfaction with surgery (p = 0.0141). Multivariate analysis detected two factors associated with CR: disease duration over 60 months and less than two previous balloon dilatations. CONCLUSIONS LHD improved chest pain symptoms in 90% of patients with achalasia. The patients who achieved relief of chest pain were characterized by disease duration over 60 months and less than two previous balloon dilatations.

Abstract
To apply a laser ion source that generates a high-intensity pulsed beam to high-dose applications, such as ion implantation, a high repetition rate operation with a short pulse interval is required. However, when the pulse interval is shortened, there is a concern that a plasma, which is different from a single pulse plasma generation, may be formed due to the interaction between the preceding and following pulses. We investigated the time interval in which plasma pulses are generated without pulse-to-pulse interaction using a laser ion source with two lasers. In the experiment, a graphite target was irradiated by two laser beams (1064-nm wavelengths) with the same pulse widths (5.4 ns) and energies (15 mJ, 30 mJ, and 45 mJ) at different time intervals ranging from 1000 μs to 0 µs, and the time integrated value corresponding to the total charge amount was calculated from the measured time-of-flight signal of the generated carbon ion current. It was observed that the total charge did not change when the time interval was as low as approximately 100 µs, and the total charge rapidly decreased when the time interval was below approximately 100 µs. Thus, it was determined that the interaction occurs within a time interval of approximately 100 µs.

Abstract
Ion implanters require various kinds of heavy-ion beams in low-charge states for material science experiments. For this purpose, a laser ion source has been developed for the ion implanter at Takasaki Ion Accelerators for Advanced Radiation Application. In this study, we investigated the particle number of ions per laser pulse for each charge state in the laser-produced carbon plasma. In the experiment, the carbon plasma was generated from a graphite target using a Nd:YAG laser (1064 nm wavelength, 5 ns pulse width) at a laser energy of 37.5 mJ, 28.3 mJ, or 15.6 mJ. The particle number of ions in the plasma was evaluated from the time-integrated value of each ion-charge-state's current signal by placing the focusing lens at various positions. We found that the particle number of carbon ions was the highest for singly charged ions at all laser energies, with particle number in the order of 1010 ions obtained at a 1-m distance from the target surface.

Abstract
Essentials Acquired Glanzmann thrombasthenia (aGT) is generally caused by function-blocking antibodies (Abs). We demonstrated a unique aGT case due to marked reduction of αIIbβ3 with anti-αIIbβ3 Abs. The anti-αIIbβ3 Abs of the patient did not inhibit platelet function but reduced surface αIIbβ3. Internalization of αIIbβ3 induced by the Abs binding may be responsible for the phenotype. SUMMARY: Background Acquired Glanzmann thrombasthenia (aGT) is a bleeding disorder generally caused by function-blocking anti-αIIbβ3 autoantibodies. Aim We characterize an unusual case of aGT caused by marked reduction of surface αIIbβ3 with non-function-blocking anti-αIIbβ3 antibodies (Abs). Methods A 72-year-old male suffering from immune thrombocytopenia since his 50s showed exacerbation of bleeding symptom despite mild thrombocytopenia. Platelet aggregation was absent with all agonists but ristocetin. Analysis of αIIbβ3 expression and genetic analysis were performed. We also analyzed effects of anti-αIIbβ3 Abs of the patient on platelet function and αIIbβ3 expression. Results Surface αIIbβ3 expression was markedly reduced to around 5% of normal, whereas his platelets contained αIIbβ3 to the amount of 40-50% of normal. A substantial amount of fibrinogen was also detected in his platelets. There were no abnormalities in ITGA2B and ITGB3 cDNA. These results indicated that reduced surface αIIbβ3 expression caused a GT phenotype, and active internalization of αIIbβ3 was suggested. Anti-αIIbβ3 IgG Abs were detected in platelet eluate and plasma. These Abs did not inhibit PAC-1 binding, indicating that the Abs were non-function-blocking. Surface αIIbβ3 expression of a megakaryocytic cell line and cultured megakaryocytes tended to be impaired by incubation with the patient's Abs. After 2 years of aGT diagnosis, his bleeding symptom improved and surface αIIbβ3 expression was recovered to 20% of normal with reduction of anti-αIIbβ3 Abs. Conclusion We demonstrated a unique aGT phenotype due to marked reduction of surface αIIbβ3. Internalization induced by anti-αIIbβ3 Abs may be responsible in part for the phenotype.

Abstract
BACKGROUND Balloon dilatation is reportedly less effective for young patients with esophageal achalasia than for older patients. However, there is no consensus on the impact of prior balloon dilatation on outcomes of surgical treatment. This study investigated the significance of preoperative balloon dilatation on surgical outcomes in young patients with esophageal achalasia. METHODS Of patients aged less than 40 years who had undergone a laparoscopic Heller-Dor operation for esophageal achalasia, 201 with a postoperative follow-up period of at least 1 year were included. They were divided into two groups with and without a history of balloon dilatation, and compared preoperative pathological conditions and surgical outcomes. RESULTS This study included 100 men and 101 women with a median age of 31 years, of whom 158 patients without a history of pneumatic dilatation (79%, non-PD group) and 43 with a history of pneumatic dilatation (21%, PD group) The preoperative symptom scores for dysphagia and regurgitation were significantly higher in the non-PD group. Although no differences were observed in surgical outcomes or postoperative course, the esophageal clearance rates calculated on preoperative and postoperative timed barium esophagograms were lower in terms of both height and width of the barium column in the PD group than in the non-PD group. Subjectively, both groups expressed equally high satisfaction. CONCLUSIONS In patients aged less than 40 years with esophageal achalasia, although preoperative balloon dilatation did not affect subjective levels of satisfaction with surgery, postoperative improvement in esophageal clearance in the lower esophagus was inhibited.

Abstract
BACKGROUND Clinical role of low-dose aspirin (LDA) in pathogenesis of gastroesophageal reflux disease is by far controversial. This can be attributed to the paucity of basic research detailing the mechanism of LDA-induced esophageal mucosal injury (EI) on underlying chronic acid reflux esophagitis (RE). AIM The aim of this study was to clarify the effect of LDA on chronic RE in rats. METHODS Esophagitis was induced in 8-week-old male Wistar rats by ligating the border between forestomach and glandular portion with a 2-0 silk tie and covering the duodenum with a small piece of 18-Fr Nélaton catheter. Seventy-eight chronic RE rat models were divided into five treatment groups, consisting of orally administered vehicle (controls), and aspirin doses of 2, 5, 50 or 100 mg/kg once daily for 28 days. EI was assessed by gross area of macroscopic mucosal injury, severity grade of esophagitis and microscopic depth of infiltration by inflammatory cells. RESULTS Area of esophagitis in animals with aspirin dose of 100 mg/kg/day showed a 36.5% increase compared with controls, although it failed to achieve statistical significance (p = 0.812). Additionally, the rate of severe EI was increased in animals with aspirin dose of 100 mg/kg/day as compared with controls (p < 0.05). The grade of severity correlated with the depth of inflammation (r s = 0.492, p < 0.001). CONCLUSIONS Maximal dose aspirin (100 mg/kg/day) contributed in exacerbating preexisting EI. LDA (2 and 5 mg/kg/day), on the other hand, did not affect chronic RE in this model. LDA seems to be safe for use in patients with chronic RE.

Abstract
PURPOSE In the present study, we examined how the body mass index (BMI) affected the outcomes of laparoscopic fundoplication for GERD in patients, whose backgrounds were matched in a propensity score-matched analysis. METHODS We divided the patients into two groups (BMI <25 kg/m2 and BMI ≥25 kg/m2). The following background information was matched for the propensity score-matched analysis: sex, age, degree of esophageal hiatal hernia, acid exposure time, and degree of reflux esophagitis. In total, 105 subjects were extracted in each group. The surgical outcomes and postoperative outcomes of patients with BMI <25 kg/m2 (Group A) and those with BMI ≥25 kg/m2 (Group B) were compared and examined. RESULTS There were no differences in the surgical procedure, intraoperative complications, or estimated blood loss (p = 0.876, p = 0.516, p = 0.438, respectively); however, the operative time was significantly prolonged in Group B (p = 0.003). The rate of postoperative recurrence in Group A was 17% (15/87 patients), while that in Group B was 11% (12/91 patients), and did not differ to a statistically significant extent (p = 0.533). CONCLUSIONS Although the operative time for GERD in obese patients was prolonged in comparison with non-obese patients, there was no difference in the rate of postoperative recurrence.

Abstract
Purpose Although laparoscopic Heller myotomy and Dor fundoplication (LHD) is widely performed to address achalasia, little is known about the learning curve for this technique. We assessed the learning curve for performing LHD. Methods Of the 514 cases with LHD performed between August 1994 and March 2016, the surgical outcomes of 463 cases were evaluated after excluding 50 cases with reduced port surgery and one case with the simultaneous performance of laparoscopic distal partial gastrectomy. A receiver operating characteristic (ROC) curve analysis was used to identify the cut-off value for the number of surgical experiences necessary to become proficient with LHD, which was defined as the completion of the learning curve. Results We defined the completion of the learning curve when the following 3 conditions were satisfied. 1) The operation time was less than 165 minutes. 2) There was no blood loss. 3) There was no intraoperative complication. In order to establish the appropriate number of surgical experiences required to complete the learning curve, the cut-off value was evaluated by using a ROC curve (AUC 0.717, p < 0.001). Finally, we identified the cut-off value as 16 surgical cases (sensitivity 0.706, specificity 0.646). Conclusion Learning curve seems to complete after performing 16 cases.

Abstract
As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in Japan concerning the epidemiology, pathophysiology, treatment, and Barrett's esophagus during this period. By incorporating the contents of these reports, the guidelines were completely revised, and a new edition was published in October 2015. The revised edition consists of eight items: epidemiology, pathophysiology, diagnosis, internal treatment, surgical treatment, esophagitis after surgery of the upper gastrointestinal tract, extraesophageal symptoms, and Barrett's esophagus. This paper summarizes these guidelines, particularly the parts related to the treatment for GERD. In the present revision, aggressive proton pump inhibitor (PPI) maintenance therapy is recommended for severe erosive GERD, and on-demand therapy or continuous maintenance therapy is recommended for mild erosive GERD or PPI-responsive non-erosive GERD. Moreover, PPI-resistant GERD (insufficient symptomatic improvement and/or esophageal mucosal break persisting despite the administration of PPI at a standard dose for 8 weeks) is defined, and a standard-dose PPI twice a day, change in PPI, change in the PPI timing of dosing, addition of a prokinetic drug, addition of rikkunshito (traditional Japanese herbal medicine), and addition of histamine H2-receptor antagonist are recommended for its treatment. If no improvement is observed even after these treatments, pathophysiological evaluation with esophageal impedance-pH monitoring or esophageal manometry at an expert facility for diseases of the esophagus is recommended.

Abstract
In general, the treatment methods for esophageal achalasia are largely classified into four groups, including drug therapy using nitrite or a calcium channel blocker, botulinum toxin injection, endoscopic therapy such as endoscopic balloon dilation, and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913, but the most common approach has changed from open-chest surgery to laparoscopic surgery. Currently, the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy, to thoracoscopic surgery, and to laparoscopic surgery, the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux, but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently, a new endoscopic approach, peroral endoscopic myotomy (POEM), has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.

Abstract
PURPOSE To clarify the feasibility and utility of reduced port surgery (RPS) for achalasia. METHODS Between September 2005 and June 2013, 359 patients with esophageal achalasia, excluding cases of reoperation, underwent laparoscopic Heller myotomy and Dor fundoplication (LHD) according to our clinical pathway. Three-hundred and twenty-seven patients underwent LHD with five incisions (conventional approach), while the other 32 patients underwent RPS, including eight via SILS. The clinical data were collected in a prospective fashion and retrospectively reviewed. We selected 24 patients matched for gender, age and morphologic type with patients in the RPS group from among the 327 patients (C group). The surgical outcomes were compared between the C and RPS groups. RESULTS There were no significant differences between the two groups in the duration of symptoms, dysphagia score, chest pain score, shape of the distal esophagus and esophageal clearance. The operative time was significantly longer in the RPS group than in the C group (p < 0.001). There were no significant differences between the two groups in the length of postoperative hospital stay or rates of bleeding, mucosal injury of the esophagus and/or stomach and postoperative complications. The symptom scores significantly improved after surgery in both groups (p < 0.001). Furthermore, there were no significant differences between the C group and RPS group in terms of the postoperative symptom scores or satisfaction scores after surgery. CONCLUSIONS The surgical outcomes of RPS for achalasia are comparable to those obtained with the conventional method.

Abstract
BACKGROUND/AIMS Soft pancreases are susceptible to developing pancreatic fistula following pancreaticoduodenectomy. To reduce the incidence of pancreatic fistula after pancreaticoduodenectomy in patients with a soft pancreas, we developed a triple secured technique. In this study, we describe the details of this technique and also report on the postoperative outcomes. METHODOLOGY The triple secured technique employed an ultrasonic dissector for pancreatic transection with skeletonizing and ligating of the small pancreatic branch ducts, duct-invagination or duct-to-mucosa anastomosis for main pancreatic duct management, and, finally, four large stitches between the pancreatic stump parenchyma and the jejunal seromuscular layer to prevent minor pancreatic leakage. A total of 28 consecutive patients with a soft pancreas who underwent pancreaticoduodenectomy using our technique were included in this study. RESULTS Postopetrative complications occurred in 16 patients. Grade B pancreatic fistula developed in 6 patients. However, no grade C pancreatic fistula occurred in this series. Neither any reoperation nor in-hospital mortality was observed in this series. CONCLUSIONS Our triple secured technique after pancreaticoduodenectomy was feasible and safe, with an acceptable rate of grade B pancreatic fistula and no grade C pancreatic fistula for patients with a soft pancreas.

Abstract
BACKGROUND/AIM Ubiquitin-conjugating enzyme H10 (UBCH10) is required in the cell-cycle transition from metaphase to anaphase. Therefore, we investigated whether its expression level in cancerous esophageal lesions affected prognosis of patients with esophageal squamous-cell carcinoma. MATERIALS AND METHODS Paraffin-embedded tissue samples from 121 patients with esophageal squamous cell carcinoma were stained with antibody to UBCH10 for immunohistochemical analysis. RESULTS UBCH10 was expressed in cancerous and dysplastic lesions, but not in normal tissue. Patients were grouped according to expression: High (N=33) or low (N=88), depending on the staining pattern. There were significant differences between the groups in terms of invasion into lymphatic vessels, number of metastatic lymph nodes, TNM classification, and stages, as well as in survival: the 50% survival rate in the high expression group was 2.3 years, whereas it was 9.9 years for the low-expression group (p<0.0001). Even with multivariate adjusting for stage 0 to stage IV using the Cox proportional hazard model, patients belonging to the high-expression group had a poor prognosis (Hazard ratio=2.5; 95% Confidence Interval=1.3-4.5; p=0.004). CONCLUSION High protein expression of UBCH10 is a marker of poor prognosis in esophageal squamous cell carcinoma.

Abstract
A transverse beam emittance and acceptance measurement system has been developed to visualize the relationship between the injected beam emittance and the acceptance of a cyclotron. The system is composed of a steering magnet, two pairs of slits to limit the horizontal and vertical phase-space, a beam intensity detector just behind the slits for the emittance measurement, and a beam intensity detector in the cyclotron for the acceptance measurement. The emittance is obtained by scanning the slits and measuring the beam intensity distribution. The acceptance is obtained by measuring the distribution of relative beam transmission by injecting small emittance beams at various positions in a transverse phase-space using the slits. In the acceptance measurement, the beam from an ion source is deflected to the defined region by the slits using the steering magnet so that measurable acceptance area covers a region outside the injection beam emittance. Measurement tests were carried out under the condition of accelerating a beam of (16)O(6+) from 50.2 keV to 160 MeV. The emittance of the injected beam and the acceptance for accelerating and transporting the beam to the entrance of the extraction deflector were successfully measured. The relationship between the emittance and acceptance is visualized by displaying the results in the same phase-plane.

Abstract
A 39-year-old female patient was referred to our hospital with a suspected esophageal motility disorder following a 4-month history of hiccup and dysphagia. Her past medical and family histories were unremarkable. Prior investigation with upper gastrointestinal endoscopy and esophagography failed to demonstrate any obvious pathology. Therefore, high-resolution manometry was performed, which showed the following: an integrated relaxation pressure (IRP) of 11.5mmHg; a distal contractile integral (DCI) of 6543mmHg-s-cm; and, a highest DCI of 9289mmHg-s-cm. A diagnosis of jackhammer esophagus was, therefore, considered. We reported on the details of this case and reviewed the relevant literature.

Abstract
The diagnosis of the rare neoplasm histiocytic sarcoma (HS) relies on morphology and the presence of immunophenotypic features of histiocytic lineage. More than 57 cases, including 16 cases involving the gastrointestinal (GI) tract, have been described since the World Health Organization issued its classification system for tumors of hematopoietic and lymphoid tissue in 2001. HS is often diagnosed in its late stages, at which point the prognosis is poor. Only a small proportion of these patients can undergo surgical resection with curative intent. The present report describes how HS can be diagnosed at a stage of favorable prognosis using balloon enteroscopy (BE), thereby enabling surgical resection before the development of metastases. This strategy is reviewed in the setting of a patient with jejunal HS, followed by a discussion of data from 16 other reported cases of GI HS.

Abstract
The etiology of achalasia is believed to be the neuropathy associated with chronic inflammation of the nerve plexus, but the cause of plexus inflammation is unknown. The purpose of this study was to evaluate the pathophysiology of achalasia by examining the muscularis externa of the esophagus. We used the muscularis externa of the esophagus of 62 patients with achalasia (median 44 years, male : female 32:30) who underwent surgical treatment (achalasia group) and of 10 patients (median 65.5 years, male : female 9:1) who underwent esophagectomy for thoracic esophageal cancer (control group) to perform immunohistochemical staining with S-100, CD43, c-kit (CD117), n-NOS, vasoactive intestinal polypeptide (VIP), and ubiquitin. The cell counts that were positive for S-100, n-NOS, VIP, and ubiquitin were significantly lower in the achalasia group compared with the control group (P < 0.001, P= 0.001, P < 0.001, and P= 0.001, respectively). There were no statistically significant differences with respect to CD43 and c-kit staining (P= 0.586 and P= 0.209, respectively). In conclusion, the pathophysiology of achalasia is therefore considered to be an impaired production of NO and VIP, which both affect interstitial cell of Cajal and smooth muscles, and this impairment is therefore considered to play a role in the pathophysiology of achalasia.

Abstract
PURPOSE To define the factors predisposing to recurrence and evaluate the results of reoperations for achalasia. METHODS We reviewed the medical records of ten patients (4 men and 6 women; mean age, 51.5 ± 11.0 years), who underwent reoperations for achalasia between August 1994 and August 2010. RESULTS The primary surgical procedures were Heller-Dor (HD) cardioplasty in nine patients and Heller myotomy in one patient. The factors contributing to failure of the primary operation included inadequate myotomy (n = 2), recurrent adhesion after myotomy (n = 2), reflux esophagitis (n = 2), difficulty in passage caused by tortuosity of the esophagus (n = 2), difficulty in passage through the thoracic esophagus (n = 1), and severe chest pain (n = 1). The reoperations included repeated HD procedures (n = 4), repair of an esophageal hiatal hernia (n = 2), thoracic esophageal myotomy (n = 2), straightening of the lower esophagus with gastropexy (n = 1), and subtotal esophagectomy (n = 1). The success rate of the reoperations for resolving symptoms was 90 % (9 patients). CONCLUSION Selecting surgical procedures based on the causes and conditions of recurrence led to symptomatic improvement and acceptable outcomes.

Abstract
BACKGROUND The clinical application of sentinel node navigation surgery (SNNS) for patients with gastric cancer requires accurate intraoperative diagnosis of lymph node metastasis. However, the clinical significance of the diagnosis of lymph node micrometastasis for gastric cancer has not been established. In this study, we evaluated lymph nodes dissected during SNNS by immunohistochemistry with anti-cytokeratin antibody (IHC) staining for gastric cancer to investigate the usefulness of SNNS. PATIENTS AND METHODS The subjects were 130 patients with gastric cancer (3,381 lymph nodes) who underwent SNNS with infrared ray observation and lymph node dissection of D1+α or more. The dissected lymph nodes were stained with IHC (CAM 5.2), and the results were compared with intra- and postoperative diagnoses by hematoxylin and eosin (H&E) staining. In addition, the association of metastatic lymph nodes and ICG-positive lymph nodes was examined. RESULTS The number of patients (lymph nodes) with lymph node metastasis by HE and IHC staining was 16 (52 nodes) and 31 (91 nodes), respectively. Fifteen patients (27 nodes) diagnosed with pN0 by HE staining were diagnosed to be metastatic by IHC staining. The tumor depth of these patients was pT1 in ten patients (m, 3; sm, 7) and pT2 in five (mp, 4; ss, 1). Regarding the histological type, three patients were classified as well-differentiated type, while six patients each had moderately and poorly differentiated types. The grade of lymphatic invasion was ly0 in 5, ly1 in 6, and ly2 in 4, respectively. Histological assessment of 27 IHC-positive and HE-negative cells indicated 5 single cells, 16 clusters, and 6 micrometastases. These lymph nodes were all included in the sentinel nodes (SN) identified during surgery. All but one patient (0.8%) were recurrence-free at 2-8 years after surgery (median 74.7 months). The one patient developed anastomotic recurrence 4.5 years after the first operation and died. CONCLUSION Since all 27 lymph nodes in 15 patients with metastasis by IHC staining but not by HE staining were micrometastasis or less and included in the SN, ICG-positive lymphatic basin dissection by SNNS with infrared ray observation seems to be an adequate method of lymph node dissection for gastric cancer.

Abstract
BACKGROUND/AIMS Although proximal gastrectomy has become a procedure of choice for patients' early cancer in the upper third of stomach, no clinical guide for optimal gastric resection in order to avoid postoperative jejunal ulcer is available. The aim of this study was to investigate whether determining the distribution of parietal and chief cells of the stomach using Congo red test is clinically relevant. METHODOLOGY The F-line was defined as a boundary line between fundic and intermediate area of the stomach according to the pathological findings in 29 patients who underwent total gastrectomy for early gastric cancer, whereas the f-line was regarded as a boundary line between intermediate and pyloric area. In the additional 6 patients undergoing vagus-preserving proximal gastrectomy with jejunal pouch interposition, endoscopic Congo red test was preoperatively performed to determine the F-f-line. RESULTS The distances from the pyloric ring to f-line on the lesser and greater curvatures were variable. Long-term outcomes of proximal gastrectomy guided by preoperative endoscopic Congo red test were favorable. CONCLUSIONS It is suggested that preoperative endoscopic Congo red test is useful to determine the appropriate cutting line in order to avoid postoperative jejunal ulcer after proximal gastrectomy.
