Japanese Patient Engagement Promotion Training (J-PEPT): Learning course on the implementation strategy of patient engagement.

Patient engagement for patient safety is emphasized in recent years. Therefore, the Committee on Quality and Patient Safety of the Japan Primary Care Association developed a Japanese Patient Engagement Promotion Training (J-PEPT) course. J-PEPT promotes to facilitate the implementation of PE strategies and contributes to nationwide dissemination for patient safety.

Changes in the place of death before and during the COVID-19 pandemic in Japan.

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.

Current practice of pharmacological treatment for hyperactive delirium in terminally ill cancer patients: results of a nationwide survey of Japanese palliative care physicians and liaison psychiatrists.

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.

Physicians' Beliefs and Attitudes Toward Hypoactive Delirium in The Last Days of Life.

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.

Correlation between our symptom-based scoring system and the Eckardt score for assessing patients with esophageal achalasia.

PURPOSE: The Eckardt score (ES) is a famous scoring system used for assessing achalasia patients. We studied the correlation between our scoring system and the ES and examined the relationship between each score and the pathophysiology of achalasia. METHODS: The subjects were 143 patients with diagnosed achalasia. We assessed the frequency and degree of dysphagia, regurgitation (vomiting), and chest pain on a 5-point scale from 0 to 4, with the product of the frequency and degree score defined as each symptom score (0-16). The sum of the three symptom scores was the Total Symptom Score (TSS). We then studied the correlation between the TSS and the ES, including whether these scores reflected the pathophysiology. RESULTS: The median scores were 20 for TSS and 6 for the ES, indicating a high correlation between the two scores (r = 0.7280, p < 0.0001). A relationship was found between the morphologic type and both scores (TSS: p = 0.002, ES: p = 0.0036). On creating a receiver operating characteristic (ROC) curve for the Straight type and each score, the AUC was 0.6740 for TSS and 0.6628 for ES. CONCLUSIONS: A high positive correlation was found between the TSS and the ES. Both scoring systems reflected the morphologic type well, demonstrating that the TSS was a scoring system comparable to the ES.

Relationship between esophageal achalasia subtypes and esophageal clearance.

BACKGROUND: The diagnosis and pathological evaluation of esophageal achalasia have been improved dramatically by the development of high-resolution manometry. It is currently known to be divided into three subtypes. However, the differences between subtypes in terms of esophageal clearance remain unclear. AIMS: To compare the pathology of subtypes in patients with esophageal achalasia from the perspective of esophageal clearance. METHODS: We classified the patients diagnosed with esophageal achalasia into three subtypes based on the high-resolution manometry findings and compared the patient background, esophagography findings, esophageal manometry findings, timed barium esophagogram (TBE) findings, and their symptoms. We also calculated the esophageal clearance rate from TBE to investigate the relationship with the subtypes. RESULTS: There were 71 cases of Type I, 140 cases of Type II, and 10 cases of Type III. No differences by subtype were found in patient background or symptoms. Regarding the esophageal manometry findings, the integrated relaxation pressure was high in Type II (p = 0.0006). The esophagography revealed a mild degree of esophageal flexion in Type III (p = 0.0022) and a high degree of esophageal dilation in Type I and II (p = 0.0227). The esophageal clearance rate in descending order was: Type III, II, and I (height: p = 0.0302, width: p = 0.0008). CONCLUSIONS: The subtypes by high-resolution manometry diagnosis had an association with the esophagography findings and best reflected the esophageal clearance, with no correlation to the patient backgrounds and symptoms.

Evaluation of the effectiveness of the physician education program on primary palliative care in heart failure.

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.

Redo laparoscopic Heller myotomy and Dor fundoplication versus rescue peroral endoscopic myotomy for esophageal achalasia after failed Heller myotomy: a single-institution experience.

PURPOSE: To compare the surgical outcomes of redo laparoscopic Heller-Dor procedure and rescue peroral endoscopic myotomy for patients with failed Heller myotomy. METHODS: We identified patients who had undergone redo laparoscopic Heller-Dor procedure or rescue peroral endoscopic myotomy from August 1996 to September 2019 and assessed the patients' characteristics, timed barium swallow results, symptom scores before/after surgery, surgical outcomes, and postoperative outcomes. RESULTS: Eleven patients underwent redo laparoscopic Heller-Dor procedure, and 14 underwent rescue peroral endoscopic myotomy. Blood loss (p = 0.001) and intraoperative complications rate (p = 0.003) were lower and the operative time (p > 0.001) and observation period (p = 0.009) shorter in patients who underwent rescue peroral endoscopic myotomy than in patients who underwent redo laparoscopic Heller-Dor procedure. Patients who underwent rescue peroral endoscopic myotomy had a higher rate of postoperative reflux esophagitis (p = 0.033) than those who underwent redo laparoscopic Heller-Dor procedure. After the interventions, the dysphagia symptoms were improved for both groups. Furthermore, both groups expressed satisfaction with their respective procedures. CONCLUSIONS: Rescue peroral endoscopic myotomy was associated with better surgical outcomes than redo laparoscopic Heller-Dor for patients with failed Heller myotomy. However, rescue peroral endoscopic myotomy had higher rates of postoperative reflux esophagitis.

Therapeutic effect of laparoscopic fundoplication for GERD-related disease in the elderly.

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 â‰’ 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.

Risk factors for the occurrence of peptic esophagitis following laparoscopic Heller-Dor surgery for esophageal achalasia.

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.

Association between Bathing and Survival in Patients with Advanced Cancer in Their Last Days of Life: A Prospective Cohort Study.

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.

The patient characteristics of esophageal carcinoma following laparoscopic myotomy for esophageal achalasia.

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.

Intermittent percutaneous drainage of ovarian tumour.

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.

Therapeutic effect of laparoscopic fundoplication for patients with GERD from the viewpoint of Lyon Consensus.

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.

Optimal cutoff value of integrated relaxation pressure on the esophagogastric junction to detect outflow obstruction using starlet high-resolution manometry system.

BACKGROUND: Achalasia and esophagogastric junction outflow obstruction (EGJOO) are idiopathic esophageal motility disorders characterized by impaired deglutitive relaxation of the lower esophageal sphincter (LES). High-resolution manometry (HRM) provides integrated relaxation pressure (IRP) which represents adequacy of LES relaxation. The Starlet HRM system is widely used in Japan; however, IRP values in achalasia/EGJOO patients assessed with the Starlet system have not been well studied. We propose the optimal cutoff of IRP for detecting achalasia/EGJOO using the Starlet system. METHODS: Patients undergone HRM test using the Starlet system at our institution between July 2018 and September 2020 were included. Of these, we included patients with either achalasia or EGJOO and those who had normal esophageal motility without hiatal hernia. Abnormally impaired LES relaxation (i.e., achalasia and EGJOO) was diagnosed if prolonged esophageal emptying was evident based on timed barium esophagogram (TBE). RESULTS: A total of 111 patients met study criteria. Of these, 48 patients were diagnosed with achalasia (n = 45 [type I, n = 20; type II, n = 22; type III, n = 3]) or EGJOO (n = 3). In the 48 patients who had a prolonged esophageal clearance based on TBE, IRP values distributed along a wide-range of minimal 14.1 to a maximal of 72.2 mmHg. The optimal cutoff value of IRP was 24.7 mmHg with sensitivity of 89.6% and specificity of 84.1% (AUC 0.94). CONCLUSION: The optimal cutoff value of IRP to distinguish achalasia/EGJOO was ≥ 25 mmHg using the Starlet HRM system in our cohort. This indicates that the current proposed cutoff of 26 mmHg appears to be relevant.

Is esophageal manometry essential for the diagnosis of achalasia? Identifying patients with achalasia by the esophageal clearance method.

BACKGROUND AND AIM: Achalasia is a disease characterized by inadequate relaxation of the lower esophageal sphincter (LES) and impaired peristalsis, for which esophageal motor function testing is essential in making a definitive diagnosis. However, the diffusion rate of esophageal pressure testing in Japan is low. We, therefore, examined whether achalasia could be identified by esophageal clearance testing with low-density barium (Timed Barium Esophagogram: TBE). MATERIALS AND METHODS: 126 cases (62 males, median age of 46 years), excluding those who had not undergone TBE during their initial laparoscopic Heller-Dor surgery, were chosen as the subjects from among those who were diagnosed with achalasia from November 2012 when HRM was introduced. The type of dilation, maximum esophageal transverse diameter, and esophageal clearance measurements by TBE were retrospectively examined. With respect to TBE, 200 mL of 45 weight% low-density barium was ingested as quickly as possible, after which the barium column heights (H0, H1, H2, and H5) were measured 1 min, 2 min, and 5 min following ingestion. RESULTS: The types of dilation indicated included: straight type (105 cases, 83%); sigmoid type (20 cases, 16%); and advanced sigmoid type (1 case, 1%). The maximum transverse diameter of the esophagus was 45 (34-54) mm, with Grade I (d < 30 mm) in 33 cases, Grade II (35 mm < d < 60 mm) in 75 cases, and Grade III (d < 60 mm) in 18 cases. The values for H0, H1, H2, and H5 were 162 (117-201) mm, 142 (98-199) mm, 130 (94-183) mm, and 119 (77-178) mm, respectively. 114 cases (90.5%) were not cleared after 5 min, while 12 cases (9.5%) were cleared by 5 min later (H1 = 0 + H2 = 0 + H5 = 0) and 7 cases (5.6%) by 2 min later (H1 = 0 + H2 = 0), with only 6 cases (4.8%) having complete clearance within 1 min (H1 = 0). Moreover, the degree of dilatation in patients with complete clearance within 1 min was three patients (2.4%) each for Grade I and Grade II, respectively. CONCLUSIONS: Approximately 2.4% of achalasia cases had mostly normal esophageal clearance and no esophageal dilation. Based on the state of esophageal clearance by TBE and the maximum transverse diameter of the esophagus, it seems by and large possible to identify achalasia cases.

Reduced-port surgery with the cowboy technique for a gastric submucosal tumor.

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.

Over ten-year outcomes of laparoscopic Heller-myotomy with Dor-fundoplication with achalasia: single-center experience with annual endoscopic surveillance.

BACKGROUND: Laparoscopic Heller-myotomy with Dor-fundoplication (LHD) is the standard surgical treatment for achalasia; however, surgical outcomes over a period greater than 10 years have not been well-explored. The objective of this study was to evaluate the long-term outcomes of LHD for achalasia based on a single-center experience. METHODS: Patients who underwent LHD between 1994 and 2019 were included. Of these, we excluded patients who had undergone foregut surgery or whose follow-up data were unavailable. Esophagogastroduodenoscopy (EGD) findings and postoperative persistent and/or recurrent symptoms had been assessed annually. Disease-free rates were calculated using Kaplan-Meier analysis. RESULTS: A total of 530 patients (mean age 45.0 years with 267 men) were included. The median follow-up period was 50.5 months. More than 10 years' data were available in 78 patients (14.7%). The cumulative rates of freedom from dysphagia, vomiting, chest pain, and Eckardt score > 3 at 10 years after LHD were 80.1%, 97.5%, 96.3%, and 73.5%, respectively. Probability of esophagitis during 10 years after surgery was 34.4% of patients based on Kaplan-Meier estimation. Approximately 3/4th of patients who had post-LHD esophagitis showed mild esophagitis of Los Angeles classification grade A. Fifteen patients (2.8%) were required a revision of primary LHD. Six patients (1.2%) developed esophageal cancer with an incidence was as high as 219.8/100,000 person-year. All patients with esophageal cancer were found to have early stage tumors that were successfully resected. CONCLUSIONS: Symptomatic relief post-LHD lasted for over 10 years. The incidence rate of esophageal cancer was high. Regular EGD surveillance seems to be helpful for early detection of esophageal cancer early.

Comparison of Needlescopic and Conventional Laparoscopic Fundoplication for Gastroesophageal Reflux Disease-Related Diseases: A Propensity Score-Matched Analysis.

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)].
