ABSTRACT
BACKGROUND AND AIM: This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy. METHODS: We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group. Clinical characteristics, patient status on admission, and UGIB etiology were evaluated. Treatment outcomes and adverse events were evaluated using propensity score matching (PSM), and risk factors for mortality from UGIB were investigated using Cox multivariate analysis. RESULTS: The sedation group was significantly younger, composed of a higher proportion of males, and had chronic liver disease. Blood pressure and hemoglobin level on admission were significantly higher in the sedation group. The main cause of bleeding was peptic ulcer, which was significantly higher in the nonsedation group. PSM created 133 matched pairs. The success rate of endoscopic hemostasis was similar in both groups, and procedure time was significantly shorter in the sedation group than in the nonsedation group (17.6 ± 10.0 versus 20.2 ± 10.2 min, P = 0.04). There were no significant differences in adverse events between groups. Cox multivariate analyses revealed that red blood cell transfusion [hazard ratio (HR) 4.45, P < 0.02] and rebleeding (HR 3.30, P = 0.03) were associated with increased risk of 30-day mortality from UGIB. CONCLUSIONS: Sedation reduced the procedure time during emergency endoscopy for UGIB. Sedation during emergency endoscopy for UGIB is acceptable for safe endoscopic procedures.

BACKGROUND: This study aimed to evaluate the usefulness of discharge standards in outpatients undergoing sedative endoscopy by comparing the modified post-anesthetic discharge scoring system (MPADSS) and the modified Aldrete score. METHODS: We prospectively enrolled 376 outpatients who underwent gastrointestinal endoscopy under midazolam sedation; 181 outpatients were assessed regarding discharge after sedative endoscopy using the MPADSS (group M), and 195 patients were assessed by the modified Aldrete score (group A). The clinical characteristics, types of endoscopy, endoscopic outcomes, and anesthesia outcomes were evaluated between the two groups. We compared discharge score, recovery time, and adverse events using propensity-score matching. RESULTS: Propensity-score matching created 120 matched pairs. The proportion of patients who had a recovery time within 60 min after endoscopy was significantly higher in group A than that in group M (42.5% versus 25.0%, respectively; P < 0.01). The proportion of patients who required > 120 min of recovery time after endoscopy was significantly lower in group A than that in group M (0.0% versus 5.0%, respectively; P = 0.03). However, significantly more patients had drowsiness at discharge in group A compared with group M (19.1% versus 5.0%, respectively; P < 0.01). There was no significant difference in the adverse event rate within 24 h of discharge between the groups. CONCLUSIONS: Patients assessed by the modified Aldrete score were allowed to discharge earlier than those assessed by the MPADSS. However, a patient's level of consciousness should be assessed carefully, especially in patients who visit the hospital alone.

BACKGROUND/AIMS: The present study was performed to compare the safety of sedation with propofol during endoscopic submucosal dissection (ESD) for gastric tumors under sedation in the endoscopy room by an endoscopist versus sedation in the operation room by an anesthesiologist. METHODS: In total, 638 patients with gastric tumors who underwent ESD from January 2011 to August 2017 at Ureshino Medical Center and Saga Medical Center Koseikan were retrospectively reviewed. The patients were divided into 2 groups: those who underwent ESD in the endoscopy room (Group E, n = 532) and those who underwent ESD in the operation room (Group O, n = 106). Propensity score matching was applied for evaluation. The treatment outcome of ESD and the adverse events of sedation during ESD (desaturation, hypotension, bradycardia, and arrhythmia) were compared between the 2 groups to consider the safety of ESD. RESULTS: The propensity score-matching analysis created 82 matched pairs. Adjusted comparisons between Groups E and O showed similar treatment outcomes of ESD for gastric tumors. There were no significant differences in the treatment outcomes, anesthesia time, and mean propofol dose between the 2 groups. With respect to adverse events, desaturation occurred more often in Group E than Group O (18.3 vs. 3.7%, respectively; p = 0.005). There were no significant differences in other adverse events (hypotension, bradycardia, and arrhythmia) between the 2 groups. CONCLUSION: Sedation with propofol in the operation room might be required to ensure safer application of ESD for gastric tumors. However, a decrease in the desaturation rate was the only disadvantage of sedation in the endoscopy room.

BACKGROUND: Endoscopic mucosal resection (EMR) to remove colon polyps is increasingly common in patients taking antithrombotic agents. The safety of EMR with submucosal saline injection has not been clearly demonstrated in this population. AIMS: The present study aimed to evaluate the efficacy and safety of submucosal injection of saline-epinephrine versus hypertonic saline in colorectal EMR of patients taking antithrombotic agents. METHODS: This study enrolled 204 patients taking antithrombotic agents among 995 consecutive patients who underwent colonic EMR from April 2012 to March 2018 at Ureshino Medical Center. Patients were divided into two groups according to the injected solution: saline-epinephrine or hypertonic (10%) saline (n = 102 in each group). Treatment outcomes and adverse events were evaluated in each group and risk factors for immediate and post-EMR bleeding were investigated. RESULTS: There were no differences between groups in patient or polyp characteristics. The main antithrombotic agents were low-dose aspirin, warfarin, and clopidogrel. Propensity-score matching created 80 matched pairs. Adjusted comparisons between groups showed similar en bloc resection rates (95.1% with saline-epinephrine vs. 98.0% with hypertonic saline). There were no significant differences in adverse events (immediate EMR bleeding, post-EMR bleeding, perforation, or mortality) between groups. Multivariate analyses revealed that polyp size over 10 mm was associated with an increased risk of immediate EMR bleeding (odds ratio 12.1, 95% confidence interval 2.0-74.0; P = 0.001). CONCLUSIONS: Two tested solutions in colorectal EMR were considered to be both safe and effective in patients taking antithrombotic agents.

BACKGROUND: The present study was performed to compare the safety of sedation during endoscopic submucosal dissection (ESD) in the endoscopy room versus operation room. METHODS: In total, 297 patients with gastrointestinal tumors who underwent ESD from January 2011 to December 2016 were retrospectively reviewed. The patients were divided into two groups: those who underwent ESD in the endoscopy room without propofol (Group E) versus operation room with propofol (Group O). The patient, tumor, and procedure characteristics; adverse events; and treatment outcomes were compared between the two groups. RESULTS: The patient and tumor characteristics, including age (73.6 ± 8.2 vs. 72.5 ± 9.1 years), comorbidities, and tumor size and histology, were not different between Groups E and O. The ESD procedure time was comparable between Groups E and O (105.4 ± 70.4 vs. 106.5 ± 64.4 min), and the anesthesia time was equivalent (138.3 ± 78.1 vs. 148.4 ± 68.8 min). There were no significant differences in adverse events between the two groups. During the ESD procedure, desaturation occurred significantly more often in Group E than O (12.9% vs. 4.0%, P = 0.021, odds ratio: 3.53, 95% CI: 1.17-14.4). The recovery time after ESD was significantly longer in Group E than O (180 (100-360) vs. 90 (0-180) min, P < 0.001). CONCLUSIONS: A decreased desaturation rate and shorter recovery time after ESD were the advantages of sedation in the operation room with propofol compared with sedation in the endoscopy room. These findings warrant further exploration of the advantages of safe and effective ESD for upper gastrointestinal neoplasms in the operation room.

BACKGROUND: There are few reports of the efficacy of adalimumab (ADA) for clinical remission and preventing postoperative recurrence in Crohn's disease (CD) in Asian real practice settings. We conducted a Japanese multicenter retrospective observational study. METHODS: We evaluated patients with CD who were treated with ADA at 11 medical institutions in Japan to investigate the clinical efficacy of remission up to 52 weeks and the associated factors to achieve remission with a CD Activity Index (CDAI) < 150. The effects of preventing postoperative recurrence were also evaluated. RESULTS: In 62 patients, the remission rates were 33.9, 74.2, 75.8, 77.4, and 66.1 % at 0, 4, 12, 26, and 52 weeks, respectively. Although 10 patients discontinued treatment due to primary nonresponse, secondary nonresponse, or adverse events, the ongoing treatment rate at 52 weeks was 83.9 %. Comparison of remission and non-remission on univariate analysis identified colonic type and baseline CDAI value as significant associated factors (P < 0.05). In 16 patients who received ADA to prevent postoperative recurrence, the clinical remission maintenance rate was 93.8 % and the mucosal healing rate was 64.3 % during a mean postoperative follow-up period of 32.3 months. CONCLUSIONS: ADA effectively induced remission and prevented postoperative recurrence in patients with CD in a real practice setting.

BACKGROUND: Adipocytokines are associated with energy homeostasis and mediate various immune responses and inflammatory processes. Vaspin is a novel adipocytokine that is thought to exhibit anti-inflammatory effects. AIM: We aimed to evaluate serum vaspin levels in inflammatory bowel disease (IBD) and determine its possible associations with the course and to clarify its intestinal localization. METHODS: Serum samples were obtained from patients with Crohn's disease (CD; n = 30) and ulcerative colitis (UC; n = 33) and from healthy volunteers (controls; n = 26). Enzyme-linked immunosorbent assays were performed for all patients. Vaspin immunohistochemical staining was performed for intestines affected with IBD. RESULTS: Serum vaspin concentrations were significantly higher in patients with UC than in patients with CD and controls (422.9 ± 361.9 vs. 163.4 ± 116.2 vs. 147.5 ± 89.4 pg/mL, respectively; P < 0.01). There was no difference in the serum vaspin concentrations between the patients with CD and controls. There was also no difference in the serum vaspin concentrations between the patients with active IBD and those with inactive IBD. However, the serum vaspin concentrations of most patients with UC increased after remission induction. Vaspin was expressed in the adipocytes of the mesenteric adipose tissues but not in the epithelial or inflammatory cells of large intestines of the patients with IBD. CONCLUSIONS: Serum vaspin concentrations are elevated in patients with UC and increase further after remission induction, suggesting that vaspin may aid the auxiliary diagnosis of UC and may be useful for assessing disease activity in patients.

BACKGROUND/AIMS: Operative indications for pancreatectomy in elderly patients with pancreatic disease remain controversial. We examined clinicopathological characteristics and early outcomes in each generation of 147 patients who underwent pancreatectomy. METHODOLOGY: Patients were divided into four groups: Group 1 (n=15, 10%), young patients <50 years old; Group 2 (n=65; 44%), patients at 50- 69 years old; Group 3 (n=61, 42%), patients at 70-79 years old and Group 4 (n=6, 4%), elderly patients >80 years old. Clinicopathological and surgical parameters were examined, including estimation of physiological ability and surgical stress consisting of preoperative risk score (PRS), surgical stress score (SSS) and comprehensive risk score (CRS). RESULTS: Prevalence of co-morbidity and American Society of Anesthesiologists (ASA) score increased significantly with increasing patient age (p<0.05). Extent of pancreatectomy and lymphadenectomy did not differ between groups and surgical records were similar. Tumor stage, postoperative course and complications were similar between groups. PRS and CRS increased significantly with increasing patient age (p<0.05) but SSS did not. Univariate analysis identified presence of systemic comorbidity, ASA score =2 and PRS =0.32 as factors associated with postoperative complications, but no independent predictive parameters were identified on multivariate analysis. CONCLUSIONS: Careful management and adequate decisions regarding pancreatectomy upon identification of co-morbidity, ASA score and PRS are important in elderly patients with pancreatic disease before pancreatectomy.

BACKGROUND/AIMS: Surgical resection is a radical treatment option for gallbladder carcinoma (GBC); however, it is still difficult to cure and patient prognosis is poor. An assessment of the surgical results and chemotherapy options may elucidate effective treatments. METHODOLOGY: We retrospectively examined the demographics, surgical records and outcome in 33 patients with GBC undergoing surgical resection. RESULTS: Postoperative cancer recurrence was observed in 36% of patients. Mean cancer-free survival time was 84 months and 3-year cancer-free survival rate was 70% Mean overall survival time was 96 months and 5-year overall survival rate was 52%. The 3-year cancer-free survival and the 5-year overall survival were significantly different between the final tumor stages (p<0.001). Higher CEA and CA19- 9 level were significantly related to poor overall survival (p<0.05). Macroscopically, papillary type tumor showed significantly better overall survival compared to nodular or flat types (p<0.05). Degree of invasion, node metastasis, moderate or poor differentiation, vascular or perineural invasion and invasion of the liver or hepatoduodenal ligament were significantly associated with poor overall survival (p<0.05). A cancerfree margin at the hepatic cut end and dissected periductal structures showed a significantly poor prognosis (p<0.05). The overall survival in final curability A was significantly associated with better curability than B or C (p<0.05). CONCLUSIONS: Radically extended surgical resection for GBC is necessary to obtain improved patient survival and new adjuvant chemotherapy would be expected to improve results after surgery.

The patient was a 74-year-old woman. She visited a dermatology clinic with a complaint of discomfort in the anal region. Erosion was observed in the anal region, and biopsies were performed. She was diagnosed with Bowen's disease and was referred to the dermatology department of our hospital for treatment. At our department, an endoscopic examination was performed for assessing the extent of Bowen's disease in the rectum. A retroflexed view of the anal canal revealed a slightly raised lesion with a faded color and an irregular surface. Narrow-band imaging (NBI) revealed a whitish lesion with a relatively clear margin and brown dots on the inside. Magnifying endoscopy with NBI revealed abnormal microvessels with dilatation, tortuosity, caliber change and various shapes, which were quite similar to the intrapapillary capillary loop patterns of superficial esophageal cancer. A complete transanal resection of the anal mucosa was performed thereafter. The patient was diagnosed with a well-differentiated squamous cell carcinoma on the basis of a pathological examination. An early diagnosis is critical for successful treatment of anal canal cancer. In this regard, magnifying endoscopy with NBI may be useful for determining the presence and extent of anal canal cancer.

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory disorders of the gastrointestinal tract that share similar genetic risk factors. However, while fibrotic stricture of the intestine is a major characteristic of CD; it is rarely observed in UC. Deposition of collagen in the extracellular matrix contributes to the formation of fibrotic strictures in CD, but the underlying mechanisms are unknown. In the present study, we found that heat shock protein 47 (HSP47), a stress-response protein that acts as a molecular chaperone during the processing and secretion of collagen, expressed in the intestinal tissue from patients with CD. Serum HSP47 levels and anti-HSP47 antibody titers were significantly higher in patients with CD than in those with UC. Furthermore, anti-HSP47 antibody levels correlated significantly with fibrosis in CD. In addition, HSP47 inhibition significantly suppressed collagen production in fibroblasts in vitro. These findings suggest that HSP47 is a biomarker for differentiating fibrotic from non-fibrotic forms of CD. Additionally, we propose that HSP47 could be a potential target for treating fibrosis in patients with CD.

We encountered a case of pancreatic neuroendocrine carcinoma (pNEC) diagnosed via pathological autopsy that was initially diagnosed clinically as G3 pancreatic neuroendocrine tumor (G3 pNET) and discussed the differences between these entities in the literature. A 76-year-old man was admitted to our department because of jaundice. Computed tomography revealed multiple round nodules in both lung fields, suggesting metastasis, and a mass lesion was detected in the head of the pancreas with poor contrast in the arterial phase and slight contrast enhancement in the equilibrium phase. Biopsy of the lungs and pancreas led to a diagnosis of multiple pulmonary metastases of G3 pNET. Because the lesions were unresectable, chemotherapy was administered. Treatment was started with everolimus for 5 weeks. However, the patient experienced severe loss of appetite and malaise, and the lung lesions progressed, prompting treatment discontinuation. Subsequently, the patient's disease progressed rapidly, and he died 99 days after the start of chemotherapy. We performed a pathological autopsy with the consent of the family because of the rapid tumor growth. A pathological autopsy revealed a final diagnosis of pNEC, which differed from the clinical diagnosis.

We report a case of sclerosing cholangitis caused by oral chemotherapy with S-1. A 79-year-old woman with a history of hypertension presented with epigastric discomfort. Upper gastrointestinal endoscopy revealed advanced gastric cancer in the gastric antrum and abdominal computed tomography showed multiple lymph node metastasis. The patient underwent chemotherapy with S-1. Since 2 months later, blood chemistry analysis showed liver dysfunction and hyperbilirubinemia, and chemotherapy was discontinued. Endoscopic retrograde cholangiopancreatography revealed stenosis of the bile duct at the hepatic hilum. There was no evidence of tumor in the liver. We diagnosed chemotherapy-induced sclerosing cholangitis (CISC) caused by S-1. Although treatment with ursodeoxycholic acid and corticosteroids was temporarily effective, she eventually died of CISC and gastric cancer. To the best of our knowledge, this is the first case report of CISC caused by S-1. We present this rare condition with a review of the literature.

Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic intestinal diseases of unknown etiology that present with variable disease extents and outcomes. The use of biomarkers for the diagnosis and management of IBDs is considered beneficial. Palmitoleic acid (PO) is an adipose tissue-derived mono-unsaturated free fatty acid that potentially serves as a lipokine in metabolic and inflammatory diseases. The aim of this study was to investigate the significance of PO levels in the serum of patients with UC and CD. The study included patients with UC (n = 22), patients with CD (n = 35), and controls (n = 22). The levels of serum PO were analyzed using gas chromatography. The association of serum PO levels with the clinical features and disease outcomes in IBD was examined. Serum PO levels were significantly higher in patients with CD than in controls, whereas no difference in these levels was observed between patients with UC and controls. Serum PO levels were significantly associated with the CD activity index. Additionally, high serum PO levels were associated with an increased risk of surgical intervention requirement during follow-up. In a pilot study with a few patients, high PO levels were observed in the mesenteric tissue in the active disease site of patients with CD (n = 7) compared with those with colon cancer (n = 6). Elevated serum PO levels might serve as a marker for local inflammation and prognosis in patients with CD.

A 57-year-old man was admitted to our hospital because of frequent hematochezia. Colonoscopy exhibited a submucosal tumor-like lesion in the lower rectum. Abdominal contrast-enhanced computed tomography showed a rectal arteriovenous malformation (AVM) on the right side wall of the lower rectum. The feeder was the superior rectal artery, with early venous return. Embolization of the draining vein and feeding artery of the AVM with N-butyl-2-cyanoacrylate under balloon occlusion was planned. Angiography of the superior rectal artery showed the nidus in the rectum with early venous return of contrast material. The portal vein was punctured percutaneously under ultrasound guidance, and a balloon catheter advanced to the distal part of the superior rectal vein. Venography under balloon occlusion showed the outflow vein and nidus. Transvenous and transarterial nidus embolization with N-butyl-2-cyanoacrylate under balloon occlusion was then performed. Since the embolization, there have been no further episodes of bleeding. There is no established treatment for AVMs. Successful treatment requires targeting and eradication of the nidus. We successfully performed embolization therapy for a rectal AVM via a retrograde transvenous approach. This technique may be suitable for completely eradicating the nidus without the risk of embolism.

We report a case of hepatic portal venous gas (HPVG) caused by transient type ischemic enteritis. The patient was a 65-year-old woman, previously given a diagnosis of hypertension and diabetes mellitus. She was admitted to our hospital because of vomiting and epigastric pain. Abdominal computed tomography showed dilatation of the stomach and small intestine, with hepatic portal and superior mesenteric venous gas. Upper gastrointestinal endoscopy showed diffuse edematous and erosive change, and an extensive ulcer in the duodenum. There was no muscular defence, and physical and laboratory examinations did not indicate necrotic bowel. We diagnosed as HPVG caused by ischemic enteritis, and she responded to conservative treatment. We discuss a rare case of HPVG caused by transient type ischemic enteritis with references.

While retrospective studies have compared the efficacy of anti-tumour necrosis factor (TNF) agents and tacrolimus (TAC) in ulcerative colitis (UC), information regarding first-time use of these agents is limited. The aim of our study was to investigate the short- and long-term efficacy of anti-TNF agents [adalimumab (ADA) and infliximab (IFX)] and TAC in anti-TNF agent- and TAC-naïve steroid-refractory UC patients. We evaluated 150 steroid-refractory UC patients receiving anti-TNF agents (IFX: n = 30, ADA: n = 41) or TAC (n = 79) at eight institutions in Japan. Clinical response rates at 8 weeks were 73.2% and 75.9% while remission rates were 30.1% and 25.3% in the anti-TNF and TAC groups, respectively. Logistic regression analysis showed the male sex and higher C-reactive protein to be independent factors for response to anti-TNF agents and TAC, respectively. Use of TAC was an independent factor for relapse. No differences in response to the treatment or relapse were observed between IFX and ADA. In conclusion, TAC and anti-TNF agents promoted similar short-term effects, but anti-TNF agents ensured better long-term outcomes at first-time treatment of steroid-refractory UC patients.

BACKGROUND: Small bowel obstruction (SBO) is usually caused by postoperative adhesions and malignant disease, and decompression is effective for SBO. Our previous case report suggested that a new transnasal ileus tube insertion method, the anterior balloon method (ABM), could achieve decompression for adhesive SBO. AIMS: The study aimed to investigate the effectiveness of a new method for inserting transnasal ileus tubes in patients with SBO. METHODS: Altogether, 134 patients with small bowel obstruction treated from January 2011 to December 2017 were reviewed. The patients were categorized into two groups: those with the new method that inserts an anterior balloon (ABM group: 52 patients, 2014-2017) versus those with the ordinary insertion method (OIM group: 82 patients, 2011-2014). RESULTS: The patients' characteristics and symptoms on admission were similar in the ABM and OIM groups. Adhesions were the main cause of ileus in the two groups. The insertion time duration was significantly shorter in the ABM group than in OIM group (28.4 ± 9.1 vs. 33.5 ± 13.0 min; p = 0.01). The ABM group also had significantly longer tubes than OIM group (222.4 ± 32.2 vs. 157.4 ± 31.7 cm; p < 0.001), which resulted in a significantly shorter time until clinical symptoms were relieved in ABM group. There were no significant differences in adverse events between the two groups. CONCLUSIONS: The ABM group had shorter insertion duration and longer tubes than those of OIM group. The ABM might become a preferred therapeutic choice to achieve decompression in patients with SBO.

Objective Endoscopic self-expandable metallic stent (SEMS) placement and gastrojejunostomy (GJY) are palliative treatments for malignant gastric outlet obstruction (GOO). The aim of the present study was to compare the palliative effects of these treatments and identify predictors of a poor oral intake after treatment. Methods and Patients In total, 65 patients with GOO at multiple centers in Saga, Japan, were evaluated. Thirty-eight patients underwent SEMS placement, and 27 underwent GJY from January 2010 to December 2016. The characteristics and outcomes of the two groups were compared to detect predictors of treatment failure. Results No significant differences in the technical success, clinical success, post-treatment total protein, hospital discharge, duration from eating disability to death, or post-treatment overall survival were present between the SEMS and GJY groups. More patients in the GJY group than in the SEMS group received chemotherapy (51.4% vs. 26.3%, respectively; p=0.042). The period from treatment to the first meal was longer in the GJY group than in the SEMS group (4.5 vs. 3.0 days, respectively; p=0.013). The present study did not identify any risk factors for failure of SEMS placement. Although the stent length tended to be associated with a poor prognosis, the correlation was not statistically significant (odds ratio: 0.60, 95% confidence interval: 0.36-1.01, p=0.053). Conclusion Patients with GOO started meals more promptly after SEMS than after GJY, but the clinical outcomes were not markedly different between the SEMS and GJY groups. These findings suggest that endoscopic uncovered SEMS placement might be a feasible palliative treatment for GOO.
