A case of intra-abdominal gossypiboma diagnosed preoperatively by endoscopic ultrasound fine-needle-aspiration.

Gossypiboma is an extremely rare adverse event occurring post-surgery, where surgical gauze is left within the body. If aseptically retained, it can lead to the formation of granulation tissue through chronic inflammation and adhesion with surrounding tissues, potentially persisting asymptomatically for many years. While diagnosis of this condition has been reported through various imaging modalities such as abdominal ultrasound and computed tomography, cases not presenting with typical findings are difficult for preoperative diagnosis, and instances where it is discovered postoperatively exist. Particularly when in contact with the gastrointestinal tract within the abdominal cavity, differentiation from submucosal tumors of the digestive tract becomes problematic. This report describes the imaging characteristics of endoscopic ultrasound and the usefulness of endoscopic ultrasound-fine-needle-aspiration for tissue diagnosis in the preoperative diagnosis of intra-abdominal gossypiboma.

Quality of palliative radiotherapy assessed using quality indicators: a multicenter survey†.

We sought to identify potential evidence-practice gaps in palliative radiotherapy using quality indicators (QIs), previously developed using a modified Delphi method. Seven QIs were used to assess the quality of radiotherapy for bone metastases (BoM) and brain metastases (BrM). Compliance rate was calculated as the percentage of patients for whom recommended medical care was conducted. Random effects models were used to estimate the pooled compliance rates. Of the 39 invited radiation oncologists, 29 (74%) from 29 centers participated in the survey; 13 (45%) were academic and 16 (55%) were non-academic hospitals. For the QIs, except for BoM-4, the pooled compliance rates were higher than 80%; however, for at least some of the centers, the compliance rate was lower than these pooled rates. For BoM-4 regarding steroid use concurrent with radiotherapy for malignant spinal cord compression, the pooled compliance rate was as low as 32%. For BoM-1 regarding the choice of radiation schedule, the compliance rate was higher in academic hospitals than in non-academic hospitals (P = 0.021). For BrM-3 regarding the initiation of radiotherapy without delay, the compliance rate was lower in academic hospitals than in non-academic hospitals (P = 0.016). In conclusion, overall, compliance rates were high; however, for many QIs, practice remains to be improved in at least some centers. Steroids are infrequently used concurrently with radiotherapy for malignant spinal cord compression.

Safety/efficacy of atezolizumab + bevacizumab during anti-platelet/anticoagulation therapy in unresectable hepatocellular carcinoma.

BACKGROUND AND AIMS: This study aimed to determine the safety and efficacy of atezolizumab + bevacizumab therapy in hepatocellular carcinoma patients receiving anti-platelet agents or anticoagulants. METHODS: Patients were divided into those using (IM out) and those not using (IM in) anti-platelet agents or anticoagulants, who violated the exclusion criteria of the IMbrave150 trial, and were retrospectively examined. RESULTS: The study included 185 patients (IM in: 157; IM out: 28). For first-line treatment, progression-free survival was 184 days for IM in and 266 days for IM out (p = .136). Overall survival was 603 days for IM in and not reached for IM out (p = .265), with no significant between-group difference. Similarly, there were no significant between-group differences in progression-free survival or overall survival for later-line treatment. Haemorrhagic adverse events of ≥grade 3 were observed in 11 IM in patients and 3 IM out patients. No significant factors associated with haemorrhagic adverse events of ≥grade 3 were identified in the multivariate analysis including IM out classification, whose p value was .547. Regarding thrombotic/embolic adverse events in the IM out group, one case of exacerbation of portal vein thrombosis was observed. No deaths were directly attributable to bleeding events or exacerbations of thrombosis. CONCLUSION: Atezolizumab + bevacizumab therapy shows similar safety and efficacy in patients receiving and those not receiving anti-platelet agents or anticoagulants; therefore, it can be considered for patients with hepatocellular carcinoma receiving anti-platelet agents or anticoagulants.

A case of needle tract seeding with endoscopic findings of progression over time.

An 83-year-old male underwent three transgastric punctures with endoscopic ultrasound-guided fine-needle aspiration for the examination of a pancreatic body tumor. After a diagnosis of resectable pancreatic cancer and undergoing distal pancreatectomy, the patient was administered postoperative adjuvant chemotherapy with oral S-1 for 6 months, and carcinoembryonic antigen and carbohydrate antigen 19-9 levels were bimonthly evaluated. Carbohydrate antigen 19-9 levels continually increased to 4638.1 U/mL at 45 months post-fine-needle aspiration. Endoscopic ultrasound-guided showed a 25 mm low-echoic, irregularly shaped, and heterogeneous tumor with clear margins protruding from the mucosa outside the gastric wall, and biopsy confirmed adenocarcinoma. Since the immunostaining findings of the specimen matched those of the previously resected specimen, needle tract seeding (NTS) due to puncture of the pancreatic cancer was identified as the cause. After a pylorus-preserving gastrectomy at 46 months post-fine-needle aspiration, postoperative chemotherapy initiation, comprising gemcitabine and nab-paclitaxel, was initiated; however, the patient died despite these interventions as he developed multiple peritoneal dissemination. Although rare, the incidence of NTS will increase in the future owing to the expected extended survival in post-pancreatic cancer resection cases. We suggest regular upper gastrointestinal endoscopy and endoscopic ultrasound-guided evaluations for patients who are at risk for NTS can facilitate early detection. Furthermore, it is extremely relevant to share experiences of encountered NTS cases in practice and extend knowledge of its varying endoscopic appearances.

A case of disseminated peritoneal metastases after 2-year conservative treatment for intramucosal colon carcinoma due to a perforation during endoscopic submucosal dissection.

A 70-year-old man was admitted to our hospital for the treatment of a large granular-type laterally spreading tumor in the splenic flexure of the descending colon. The preoperative diagnosis was intramucosal colon carcinoma and endoscopic submucosal dissection was performed. During treatment, a small perforation occurred accidentally. After conservative treatment with endoscopic suturing, the patient was discharged without additional surgery. The pathological diagnosis was an intramucosal carcinoma. One year after treatment, no local recurrence was observed on endoscopy, and abdominal computed tomography showed no obvious metastasis. Two years later, fluorodeoxyglucose-positron emission tomography/computed tomography, laparoscopic findings, and histopathologic findings by experimental excision of omentum revealed several disseminated peritoneal metastases from previously treated colon carcinoma. To the best of our knowledge, this is the first report of peritoneal dissemination after a small perforation during endoscopic submucosal dissection and conservative therapy for early-stage colon carcinoma. This report suggests the possibility of tumor dissemination in patients with small perforations during endoscopic procedures. Endoscopists should be aware of these rare potential risks and perform later surveillance carefully.

Influence of coronavirus disease 2019 case surges on prehospital emergency medical service for patients with trauma in Kobe, Japan.

Aim: In the current era of the coronavirus disease 2019 (COVID-19) pandemic, the responsiveness of emergency medical service (EMS) transport for patients with internal illness is often delayed. However, the influence of the COVID-19 pandemic on prehospital transport for patients with trauma has not yet been fully elucidated. This study aims to examine the effect of COVID-19 case surges on EMS transport for patients with trauma during the COVID-19 states of emergency in Kobe, Japan. Methods: EMS data during the states of emergency were compared with those in the 2019 prepandemic period. The incidence of difficulty securing hospital acceptance (four or more calls to medical institutions and ambulance staying at the scene for 30 min or more) was evaluated as a primary outcome. Secondary outcomes were the time spent at the trauma scene and the number of calls requesting hospital acceptance. The time spent at the trauma scene was stratified by trauma severity. Results: The incidence of difficulty securing hospital acceptance increased (1.2% versus 3.2%, P < 0.01). Logistic regression analysis revealed that the duration of the states of emergency was associated with difficulty securing hospital acceptance (odds ratio [OR] 2.08, 95% confidence interval 1.77-2.45; P < 0.01). Although the mean time spent at the trauma scene among the less severe, moderately severe, and severe trauma groups was prolonged, the time for the life-threatening group did not change. The number of request calls increased during the states of emergency. Conclusion: Difficulty securing hospital acceptance increased; however, the time spent at the trauma scene did not significantly change for the life-threatening group.

Palliative Radiation Therapy for Intramedullary Spinal Cord Metastasis.

BACKGROUND/AIM: The purpose of this study was to retrospectively review the outcomes of intramedullary spinal cord metastasis (ISCM) and identify predictors for ambulation after radiotherapy (RT). PATIENTS AND METHODS: We analyzed 16 lesions in 15 patients treated with RT for ISCM at our clinic from October 2009 to April 2020 to evaluate predictors for improved ambulation following RT. RESULTS: The primary diseases included nine cases of lung cancer, two cases of breast cancer, and several others. The RT schedule was primarily 30 Gy/10 fractions in seven cases, while others were applied to nine cases. The median overall survival time was 99 days. After RT, all seven patients who could walk prior to RT were still able to walk (100%), whereas only two of nine patients who could not walk prior to RT were able to walk (22%, p=0.004). CONCLUSION: Ambulation prior to RT was a significant predictor of ambulation ability after RT.

Prehospital advanced airway management of emergency medical service-witnessed traumatic out-of-hospital cardiac arrest patients: analysis of nationwide trauma registry.

Aim: Survival of traumatic out-of-hospital cardiac arrest (OHCA) is poor. Early use of advanced airway management (AAM) techniques, including endotracheal intubation and supraglottic devices, are expected to contribute to the improved survival of these patients. The aim of this study was to determine whether prehospital use of AAM improves the outcomes for emergency medical service (EMS)-witnessed traumatic OHCA. Methods: A nationwide retrospective study was carried out. Trauma patients with EMS-witnessed cardiac arrest who received cardiopulmonary resuscitation during transport were included. Patients younger than 16 years and those with missing data were excluded. We compared two groups using propensity score matching. The primary outcome was survival to discharge. The secondary outcome was return of spontaneous circulation (ROSC) on hospital arrival. A logistic regression model was used to calculate odds ratios (OR) and confidence intervals (CI). Results: After propensity score matching, 1,346 patients were enrolled (AAM 673 versus non-AAM 673). Forty-four AAM cases (6.5%) and 39 non-AAM cases (5.8%) survived. Logistic regression analysis did not show a contribution of AAM for survival to discharge (AAM 44/673 (6.5%), non-AAM 39/673 (5.8%); OR 1.12; 95% CI, 0.70-1.76; P = 0.64). However, AAM improved ROSC on admission (AAM 141/673 (21.0%), non-AAM 77/673 (11.4%); OR 2.05; 95% CI, 1.51-2.78; P < 0.001). This tendency was consistent throughout our subgroup analysis categorized by body region of the severe injury (head trauma, torso trauma, and extremity/spine trauma). Conclusions: Prehospital AAM among EMS-witnessed traumatic OHCA patients was not associated with survival to discharge; however, ROSC on hospital admission improved for the AAM patients.

Treatment of a gunshot wound (birdshot) patient with traumatic shock in a hybrid emergency room.

Background: Although the Hybrid Emergency Room System (HERS) is a relatively novel method for treating severe trauma patients, there have been few reported cases of gunshot wound patients treated in HERS. Here we report our treatment of a unique gunshot wound case, with shock, in a HERS setting. Case presentation: A 72-year-old male was transferred to our hospital due to a gunshot wound (GSW). He presented with left chest injuries and vital signs consistent with shock. While resuscitating the patient, including massive blood transfusion and surgery to control the damage, a subsequent computed tomography in HERS revealed the internal distribution of the birdshot and damage to the abdominal organs. Lower lobectomy of the left lung and laparotomy for gastrointestinal repair were performed. After a planned repeat operation and reconstruction of the left chest wall, he was discharged uneventfully. Conclusions: HERS during resuscitation was useful for helping clinicians not only to find the bullets' distribution and judge the severity of injury caused by the gunshot, but also to develop subsequent therapeutic strategies for rescuing the gunshot wound patient from a life-threatening situation.

Geriatric trauma prognosis trends over 10 years: analysis of a nationwide trauma registry.

Purpose: With Japan's population rapidly skewing toward aging, the number of geriatric trauma patients is expected to increase. Since we need to continue to improve the quality of geriatric trauma patient care, this study aimed to evaluate in-hospital mortality trends among geriatric trauma patients in Japan over a recent 10-year period. Methods: This was a retrospective cohort study of data from a Japanese nationwide trauma registry (the Japan National Trauma Data Bank) on patients admitted between January 1, 2008 and December 31, 2017. Geriatric patients were defined as those 65 years old and older. The primary outcome was to clarify in-hospital mortality trends and changes over these 10 years. Results: We identified 265 268 eligible trauma patients. Excluding those under 65 years old and those with inadequate or unknown age data, missing prognosis, out-of-hospital cardiac arrest, and burns, 107 766 patients were enrolled in this study. The total trauma patient in-hospital mortality trend was evaluated using the Cochran-Armitage test and showed a significant decrease (p<0.001). Although severe trauma patients (Injury Severity Score (ISS) ≥16) showed a significant decreasing trend (p<0.001) over time (from 26.1% to 14.5%), less-severe trauma patients (ISS <16) did not (p=0.41) (from 2.7% to 2.1%). Mixed logistic regression analysis showed that the number of year patients stayed in the hospital was significantly associated with mortality. Conclusions: While recognizing the limitations of the current analysis, our data demonstrated that prognoses for severe trauma patients over 65 years old improved dramatically over these 10 years, especially in those with severe trauma. Level of evidence: Ⅲ-retrospective cohort study.

[A case of pembrolizumab responding to recurrent small bowel mucinous adenocarcinoma with Peutz-Jeghers syndrome].

An advanced small bowel mucinous adenocarcinoma with Peutz-Jeghers syndrome was resected, and we started capecitabine plus oxaliplatin (CapeOX) as adjuvant therapy. However, local recurrence was noted, and the tumor increased even after CapeOX plus bevacizumab and fluorouracil plus leucovorin plus irinotecan plus panitumumab (FOLFIRI plus panitumumab). Pembrolizumab was administered after confirming high-frequency microsatellite instability, and the tumor shrank markedly and remained shrunk for 20 months.

[A case of disseminated carcinomatosis of the bone marrow associated with gastric cancer developed 10 years after endoscopic submucosal dissection].

A 59-year-old man was treated for early gastric cancer with endoscopic submucosal dissection (ESD) 10 years prior to the study. Two months after the first ESD, he was diagnosed with recurrence on the ESD scar and treated via ESD again. The horizontal margin could not be evaluated because of cauterization, and the patient was carefully observed. He was admitted to our hospital complaining of low backache and diagnosed with disseminated carcinomatosis of the bone marrow associated with gastric cancer after examination. Although he started chemotherapy, he died after 6 months. In this study, we report a rare case of disseminated carcinomatosis of the bone marrow associated with gastric cancer, which developed 10 years after ESD.

Characteristics of self-inflicted injury among suicidal patients: analysis of nation-wide trauma registry.

PURPOSE: Self-inflicted injury is one of the most common causes of suicide. Extremity injury is thought to occur most frequently among penetrating injury; however, epidemiology among patients attempting suicide is unknown. This study aims to find the characteristics of penetrating self-inflicted trauma patients. METHODS: This is a retrospective cohort study of Japanese nation-wide trauma registry (the Japan National Trauma Data Bank) between January 1, 2004 and December 31, 2017. Patients who attempted suicide with penetrating injury were eligible. We evaluated the occurrence of injury based on injury site (neck/face, chest, abdomen, extremity) as a dependent variable and aging as an independent variable using a generalized linear model and compare those groups with spline models. RESULTS: 4576 trauma patients were eligible. Excluding patients with missing age, missing survival data, and missing abbreviate injury score, 4183 patients were enrolled in this study. Common injury site is follows: abdomen 1772 patients (42.4%), extremity 1344 patients (32.0%), neck/face 1253 patients (30.0%), and chest 993 patients (23.7%). The occurrence of neck/face injury, chest injury, and abdominal injury increased with age. On contrary, the rate of extremity injury decreased with age. CONCLUSIONS: Among self-inflicted trauma patients, abdominal injury was the most common injury, and neck/face injury, chest injury, and abdominal injury were related with aging. On the contrary, the rate of extremity injury decreased as patients' age progressed. LEVEL OF EVIDENCE: Retrospective cohort study, Level III.

Comparison of Three Fractionation Schedules in Radiotherapy for Early Glottic Squamous Cell Carcinoma.

BACKGROUND/AIM: Radiotherapy is widely accepted as the treatment of choice for early glottic squamous cell carcinoma (EGSCC), although it varies greatly with respect to dose, dose per fraction, and treatment techniques. The study aim was to evaluate the use of accelerated fractionation strategy (AFS) for EGSCC in standard clinical practice. PATIENTS AND METHODS: Patients treated with definitive radiotherapy for EGSCC between 2008 and 2019 were retrospectively identified and received either conventional fractionation, hypofractionation, or hyperfractionation. RESULTS: One hundred six patients were analyzed, and 19, 71, and 16 patients underwent conventional fractionation, hypofractionation, and hyperfractionation, respectively. The median follow-up was 56 months. The 5-year local control and overall survival rates were 79% and 83%; 78% and 79%; and 87% and 77%, respectively, and no significant difference was observed between the fractionation schedules. CONCLUSION: Our findings confirmed the utility of AFS in standard clinical practice and support its use for patients with EGSCC.

Comparison of direct oral anticoagulant and vitamin K antagonists on outcomes among elderly and nonelderly trauma patients.

BACKGROUND: Direct oral anticoagulants (DOACs) are widely used among patients requiring anticoagulant therapy. These drugs are associated with a lower risk of bleeding than vitamin K antagonists (VKAs). However, the outcomes of elderly trauma patients receiving DOACs are not well known. METHODS: We reviewed data from trauma patients at our level I trauma center (University of Pittsburgh Medical Center, Presbyterian Hospital) seen from January 2011 to July 2018. We identified trauma patients taking DOACs or VKAs and compared these cohorts using 1:1 propensity score-matching based on patient characteristics, antiplatelet use, comorbidities, and laboratory values. The primary outcome was in-hospital mortality. Secondary outcomes included the proportion of patients discharged to skilled nursing facility/rehabilitation facility discharge or to home, and transfusion volume. RESULTS: Of 32,272 trauma patients screened, 530 were taking DOACs and 1,702 were taking VKAs. We matched 668 patients in a 1:1 ratio (DOACs group, 334 vs. VKAs group, 334). The DOACs group had similar mortality (4.8% vs. 1.6%; odds ratio (OR), 3.0; 95% confidence interval (CI), 0.31-28.8; p = 0.31) among patients younger than 65 years, but mortality differed (3.0% vs. 6.6%; OR, 0.41; 95% CI, 0.17-0.99; p = 0.048) among patients older than 65 years. The proportion of patients discharged to skilled nursing facility/rehabilitation facility (50.0% vs. 50.6%; OR, 0.98; 95% CI, 0.72-1.32; p = 0.88) and to home (40.4% vs. 38.6%; OR, 1.08; 95% CI, 0.79-1.47; p = 0.64) were similar. Patients in the DOACs group received fewer fresh frozen plasma (p = 0.032), but packed red blood cells (p = 0.86) and prothrombin complex concentrate (p = 0.48) were similar. CONCLUSION: In this matched cohort of anticoagulated trauma patients, DOACs were associated with the decreased in-hospital mortality and decreased administration of fresh frozen plasma compared with VKAs among trauma patients 65 years or older taking anticoagulant therapy. LEVEL OF EVIDENCE: Prognostic/Epidemiological, level III.

Idiopathic hypereosinophilic syndrome with formation of multiple liver mass lesions.

We report a case of idiopathic hypereosinophilic syndrome (IHES) characterized by multiple liver mass lesions in an 82-year-old man. Numerous hypoechoic lesions were observed on ultrasonography and were mainly distributed in the S4, S6, and S7 segments. Plain computed tomography (CT) scans revealed low-density lesions. Dynamic CT images revealed arterial and portal vein branches passing through these lesions, with marginal areas enhanced during the arterial phase. The enhanced areas were extended during the portal venous phase. Contrast-enhanced ultrasonography (CEUS) images revealed enhanced vasculature in the early vascular phase. CEUS images obtained in the late vascular phase revealed enhanced areas containing microbubbles extended into the parenchyma; a prolonged enhancement pattern was observed. Kupffer-phase images revealed large portions of the lesion filled with microbubbles and a star-like defect at the center of the nodule. F18-2-fluoro-2-deoxyglucose (FDG) positron emission tomography/CT scans revealed intense FDG uptake by these lesions, which was similar to that by the segments S4, S6, and S7. Liver biopsy revealed diffused eosinophils infiltrated. The patient was closely followed up and was completely cured 11 weeks later without any treatment. This is a rare case of IHES with multiple liver mass lesions, which was well researched using multi-imaging equipment and cured without any treatment.

The psoas muscle index as a predictor of mortality and morbidity of geriatric trauma patients: experience of a major trauma center in Kobe.

PURPOSE: An association between the prognoses of trauma and sarcopenia has not been well documented. The purpose of this study was to compare the outcomes of elderly Japanese trauma patients with sarcopenia and those without sarcopenia. METHODS: The medical records of patients aged ≧ 65 years old and Injury Severity Scores above 15 treated for trauma between 2010 and 2017 were reviewed, retrospectively. We measured the psoas muscle index (PMI), defined as the psoas muscle area at the third lumbar vertebra level divided by the body surface area. Patients of each gender with a PMI less than the lower interquartile range were included in the sarcopenia group. A questionnaire was mailed to the patients or their families to collect data on 1-year mortality and activities of daily living. RESULTS: There were 405 patients included in this study: 304 in the non-sarcopenia group (Group NS) and 101 in the sarcopenia group (Group S). Mortality was significantly higher in Group S than in Group NS (NS; 7.9% vs. S; 15.8%, OR, 2.20; 95% CI, 1.12-4.32; p = 0.027). Only 175 of the questionnaires were completed and the responses did not reveal any significant differences between the groups. CONCLUSIONS: Sarcopenia as defined by the PMI may be used as an indicator for mortality risk for geriatric trauma patients.

Gas flux cyclic regime at an open vent magmatic column inferred from seismic and acoustic records.

On August 7, 2014, a new effusive vent opened on the northern flank of Stromboli. A characteristic pattern was observed in both seismic and infrasonic signal amplitudes prior to this effusive eruption. The pattern consisted of the repeating cycle: (1) quiet phase, (2) puffing phase, and (3) explosion phase. Correlation between seismic and infrasound signal suggests that pulses in the puffing phase were caused by repetitive bursts of small gas pockets at the central crater, while the explosion phase coincided with an explosion at the central crater. We show that degassing of the magma column occurred in cycles of increasing gas flux, which controlled the transition from a bubbly flow (puffing phase), to a slug flow (explosion phase) gas regime. The quiet phase was characterized by a constant time length of 150 s, indicating that the gas rose in the magma column as well-organized waves of gas layers. These cycles represent cyclic changes of the gas flux regime in the shallow magma column, associated with increases in the magma-gas supply input rate before the effusive eruption.

Definitive Radiotherapy for Older Patients Aged ≥75 Years With Localized Esophageal Cancer.

BACKGROUND/AIM: To evaluate the predictive factors in older patients with localized esophageal cancer treated with definitive radiotherapy. PATIENTS AND METHODS: We retrospectively analyzed patients aged ≥75 years who were treated with three-dimensional conformal radiotherapy between 2008 and 2017. The patients were classified into the oldest-old group (≥80 years) and the old group (75-79 years). RESULTS: Fifty patients were identified, 28 in the oldest-old group and 22 in the old group. Forty-six patients (92%) completed the planned radiotherapy. The median follow-up time was 21 months. Two-year overall survival (OS), disease-free survival, and locoregional control rates were 53%, 42%, and 51%, respectively. Univariate analyses for OS showed that neither the radiotherapy field nor total radiotherapy dose was a significant factor. Clinical T stage, clinical N stage, and age were independent predictors of OS. CONCLUSION: Age ≥80 years is an independent prognostic factor for OS. Elective nodal irradiation and total radiotherapy dose above 50.4 Gy did not improve survival. Our findings may help in the treatment decisions for localized esophageal cancer in older patients.
