RESUMEN

BACKGROUND: Risk stratification before endoscopy is crucial for proper management of patients suspected as having upper gastrointestinal bleeding (UGIB). There is no consensus regarding the role of nasogastric lavage for risk stratification. In this study, we investigated the usefulness of nasogastric lavage to identify patients with UGIB requiring endoscopic examination. METHODS: From January 2017 to December 2018, patients who visited the emergency department with a clinical suspicion of UGIB and who underwent nasogastric lavage before endoscopy were eligible. Patients with esophagogastric variceal bleeding were excluded. The added predictive ability of nasogastric lavage to the Glasgow-Blatchford score (GBS) was estimated using category-free net reclassification improvement and integrated discrimination improvement. RESULTS: Data for 487 patients with nonvariceal UGIB were analyzed. The nasogastric aspirate was bloody in 67 patients (13.8 %), coffee-ground in 227 patients (46.6 %), and clear in 193 patients (39.6 %). The gross appearance of the nasogastric aspirate was associated with the presence of UGIB. Model comparisons showed that addition of nasogastric lavage findings to the GBS improved the performance of the model to predict the presence of UGIB. Subgroup analysis showed that nasogastric lavage improved the performance of the prediction model in patients with the GBS ≤ 11, whereas no additive value was found when the GBS was greater than 11. CONCLUSIONS: Nasogastric lavage is useful for predicting the presence of UGIB in a subgroup of patients, while its clinical utility is limited in high-risk patients with a GBS of 12 or more.

RESUMEN

BACKGROUND: Ingested foreign objects frequently require emergency removal. This study aimed to investigate the clinical outcomes of endoscopic removal of foreign bodies from the upper gastrointestinal tract and the risk factors for adverse events. METHODS: Adults (> 18 years) who underwent endoscopic management of ingested foreign bodies at two centers, one inland and one on the coast, between January 2008 and December 2017 were eligible. Clinical characteristics and procedure-related outcomes were retrospectively reviewed. Patients were divided into two groups, based on whether the foreign bodies were sharp or blunt in shape. RESULTS: A total of 853 patients aged 19-96 years were analyzed. Ingestion of fish bones was more common in the coastal area, whereas ingestion of food boluses was more common in the inland area. The duration of impaction ranged from 1 h to over 1 month and was significantly longer in patients who ingested blunt than sharp foreign bodies (15 vs. 5 h, p < 0.001). Most (98.9%) foreign bodies were successfully removed. Adverse events occurred in 31.2 % of patients, including ulcers (4.0%) and perforations (3.3 %). Multivariate analysis showed that age (odds ratio [OR] 1.015, p = 0.012), sharp foreign bodies (OR 5.133, p < 0.001), location in the esophagus (OR 2.723, p = 0.018), and duration of impaction (OR 1.431, p < 0.001) were factors associated with adverse events. CONCLUSIONS: Early recognition and timely endoscopic removal of ingested foreign bodies, particularly in elderly patients and those with sharp foreign bodies, may improve clinical outcomes.

RESUMEN

OBJECTIVES: The optimal duration of fasting after endoscopic hemostasis in patients with peptic ulcer bleeding has not yet been determined. We investigated the appropriate timing of feeding after endoscopic hemostasis in patients with high-risk peptic ulcer bleeding. METHODS: This study was a randomized, single center, noninferiority trial. Between February 2014 and March 2019, consecutive patients with peptic ulcer bleeding were randomized to resume feeding either 24 or 48 hours after successful endoscopic hemostasis. A total of 209 eligible patients were included in the intention-to-treat analysis and 200 in the per-protocol (PP) analysis. The primary outcome measure was recurrent bleeding within 7 days of hemostasis. Noninferiority testing was performed in the PP population, and the noninferiority margin was set at 10%. Secondary outcomes included 30-day rebleeding and mortality, transfusion requirements, and length of hospital stay. RESULTS: Recurrent bleeding rates at 7 days were 7.9% in the 24-hour group and 4.0% in the 48-hour group in the PP analysis; tests for noninferiority did not reach statistical significance (difference: 3.9%, 95% confidence interval [CI]: -2.7 to 10.5, P value for noninferiority = 0.034). The recurrent bleeding rates within 30 days were 10.9% and 4.0% in the 24- and 48-hour groups (difference: 6.9%, 95% CI: -0.5 to 14.2), and the 30-day mortality rates were 5.9% and 14.1%, respectively (difference: -8.2%, 95% CI: -16.5 to 0.1) in the PP analysis. The transfusion requirement and the length of hospital stay were similar between the 2 groups. DISCUSSION: Early refeeding at 24 hours after endoscopic hemostasis is not noninferior to later refeeding at 48 hours for rebleeding in patients with high-risk peptic ulcer bleeding. Our results do not allow a recommendation of refeeding at 24 hours, rather than later refeeding in this population.

RESUMEN

KEY POINTS: Activation of focal adhesion kinase (FAK) by integrin signalling facilitates smooth muscle contraction by transmitting the force generated by myofilament activation to the extracellular matrix and throughout the smooth muscle tissue. Here we report that electrical field stimulation (EFS) of cholinergic motor neurons activates FAK in gastric fundus smooth muscles, and that FAK activation by EFS is atropine-sensitive but nicardipine-insensitive. PDBu and calyculin A contracted gastric fundus muscles Ca2+ -independently and also activated FAK. Inhibition of FAK activation inhibits the contractile responses evoked by EFS, and inhibits CPI-17 phosphorylation at T38. This study indicates that mechanical force or tension is sufficient to activate FAK, and that FAK appears to be involved in the activation of the protein kinase C-CPI-17 Ca2+ sensitization pathway in gastric fundus smooth muscles. These results reveal a novel role for FAK in gastric fundus smooth muscle contraction by facilitating CPI-17 phosphorylation. ABSTRACT: Smooth muscle contraction involves regulating myosin light chain phosphorylation and dephosphorylation by myosin light chain kinase and myosin light chain phosphatase. C-kinase potentiated protein phosphatase-1 inhibitor of 17 kDa (CPI-17) and myosin phosphatase targeting subunit of myosin light-chain phosphatase (MYPT1) are crucial for regulating gastrointestinal smooth muscle contraction by inhibiting myosin light chain phosphatase. Integrin signalling involves the dynamic recruitment of several proteins, including focal adhesion kinase (FAK), to focal adhesions. FAK tyrosine kinase activation is involved in cell adhesion to the extracellular matrix via integrin signalling. FAK participates in linking the force generated by myofilament activation to the extracellular matrix and throughout the smooth muscle tissue. Here, we show that cholinergic stimulation activates FAK in gastric fundus smooth muscles. Electrical field stimulation in the presence of Nω -nitro-l-arginine methyl ester and MRS2500 contracted gastric fundus smooth muscle strips and increased FAK Y397 phosphorylation (pY397). Atropine blocked the contractions and prevented the increase in pY397. The FAK inhibitor PF-431396 inhibited the contractions and the increase in pY397. PF-431396 also inhibited the electrical field stimulation-induced increase in CPI-17 T38 phosphorylation, and reduced MYPT1 T696 and T853, and myosin light chain S19 phosphorylation. Ca2+ influx was unaffected by PF-431396. Nicardipine inhibited the contractions but had no effect on the increase in pY397. Phorbol 12,13-dibutyrate or calyculin A contracted gastric fundus smooth muscle strips Ca2+ independently and increased pY397. Our findings suggest that FAK is activated by mechanical forces during contraction and reveal a novel role of FAK in the regulation of CPI-17 phosphorylation.

RESUMEN

Colorectal micropapillary carcinoma has recently been reported as an aggressive variant of adenocarcinoma with a high incidence of lymph node metastasis, but has not been well investigated in terms of survival analysis. This study analyzed the clinicopathological characteristics, including survival data, of the patients with micropapillary carcinoma. We hypothesized that the aggressive features of micropapillary carcinoma might be related to the presence of more tumor cells with stem cell phenotype in colorectal cancer. Fifty-five (10%) micropapillary carcinoma cases were identified among 561 cases of colorectal cancer. We compared the clinicopathological characteristics, including survival data and immunohistochemical profiles of stem cell markers (SOX2, NOTCH3, CD44v6, CD166, ALDH1) of micropapillary carcinomas with those of randomly selected 112 conventional adenocarcinomas lacking micropapillary carcinoma components (non-micropapillary carcinoma) in the colorectum. To exclude the possibility of dilution of control group by patients with microsatellite instability-high carcinomas, we divided non-micropapillary carcinomas into microsatellite instability-high carcinoma and microsatellite stable tumors. Micropapillary carcinomas were characterized by more frequent lymphovascular invasion (P<0.0001) and lymph node metastasis (P<0.0001), higher pathological T and tumor node metastasis stages (P=0.047 and P=0.001), and more frequent SOX2 (P=0.038) and NOTCH3 expressions (P=0.005). Overall 5-year survival rate for patients with micropapillary carcinoma (37%) was significantly lower than for microsatellite instability-high carcinoma and microsatellite stable carcinoma patients (92 and 72%, P<0.0001). The presence of the micropapillary carcinoma component was shown to be associated with a significantly worse survival rate in univariate (P<0.0001) and multivariate (P=0.003, Cox hazard ratio 2.402) analyses. In conclusion, recognition of the micropapillary carcinoma component in colonic adenocarcinoma is very important, because the micropapillary carcinoma has been associated with a significantly worse prognosis. We also found a higher expression rate of cancer stem cell markers in micropapillary carcinomas, suggesting their potential contribution to the survival disadvantage of micropapillary carcinoma.

RESUMEN

The optimal timing of endoscopy in patients with acute upper gastrointestinal bleeding (UGIB) remains controversial. In this study, we investigated the clinical outcomes of urgent endoscopy in patients with UGIB compared with elective endoscopy. From January 2016 to December 2018, consecutive patients who visited the emergency department and underwent endoscopy for clinical manifestations of acute UGIB, including variceal bleeding, were eligible. Urgent endoscopy (within 6 h) and elective endoscopy (after 6 h) were defined as the time taken to perform endoscopy after presentation to the emergency department. The primary outcome was mortality rate within 30 days. A total of 572 patients were included in the analysis. Urgent endoscopy was performed in 490 patients (85.7%). The 30-day mortality rate did not differ between the urgent and elective endoscopy groups (5.3% and 6.1%, p = 0.791). There was no difference regarding the recurrent bleeding rate, total amount of transfusion, or length of hospital between the groups. In multivariate analysis, age and the amount of transfusion were associated with mortality. Urgent endoscopy was not associated with a lower 30-day mortality rate compared with elective endoscopy in patients with acute UGIB.

RESUMEN

Bismuth quadruple therapy (BQT) is an effective treatment for Helicobacter pylori infection. However, frequent dosing schedules of BQT regimen often compromise drug adherence and may affect treatment outcomes. This retrospective study aimed to investigate the efficacy of twice-daily BQT compared to that of four times a day therapy. From August 2018 to November 2020, adult patients who failed first-line standard triple therapy and underwent BQT were eligible. Patients were categorized into two groups according to dosing schedule: (i) the BQT group (n = 213) who received standard BQT administered four times a day; and (ii) the BQTb group (n = 141) who received proton pump inhibitor, bismuth 600 mg, metronidazole 500 mg, and tetracycline 1 g twice a day. The eradication rate did not differ between the BQT (92.5%) and the BQTb groups (90.1%) (p = 0.441). Adherence and adverse event rate were similar between the two groups. Multivariate analysis showed that current smoking was associated with eradication failure; however, dosing frequency was not associated with the efficacy of eradication therapy. This study suggested that twice a day BQT is as effective as four times a day therapy for second-line treatment of H. pylori infection.

RESUMEN

Pyoderma gangrenosum (PG), an ulcerating skin condition, is rare in patients with ulcerative colitis (UC). We report a case of successful treatment of PG in a patient with UC using hyperbaric oxygen therapy (HBOT). The patient had UC that was in remission following treatment with mesalazine and azathioprine therapy. After visiting an orthopedic clinic, the patient opted for treatment with antibiotics and daily dressing of the ulcerative skin lesions, while azathioprine was discontinued. However, the lesions did not improve. Two months later, the patient visited a dermatologist who diagnosed the lesions as PG, and he was admitted to our unit. Surgical debridement and HBOT were performed by a plastic surgeon in the emergency department. After 3 months of HBOT and topical treatment, the patient's PG completely resolved. His UC was still in remission with mesalazine alone. HBOT may be an effective and safe alternative treatment for PG associated with UC, particularly in patients in whom anti-tumor necrosis factor agents are unnecessary.

RESUMEN

Patients with liver cirrhosis and hepatocellular carcinoma (HCC) are often ineligible for resection or local ablation therapy due to poor liver function and/or difficult location. The aim of this study is to evaluate therapeutic outcomes of stereotactic body radiotherapy (SBRT) combined with transarterial chemoembolization (TACE) compared with TACE alone for HCC measuring less than 5 cm. From March 2011 to December 2016, 85 patients underwent SBRT with TACE (SBRT-TACE group) and 114 underwent TACE (TACE group) at 4 tertiary hospitals. Local control rate (LCR), progression-free survival (PFS) and overall survival (OS) were compared after propensity-score matching (1:1 ratio). The SBRT-TACE group showed significantly higher 1- and 3-year LCR than the TACE group (91.1% and 89.9%, respectively vs 69.9% and 44.8%, respectively; P < 0.001). The SBRT-TACE group showed better 1- and 3-year PFS than the TACE group (56.5% and 32.3%, respectively vs 42.2% and 21.6%, respectively; P = 0.022). However, 1-, 3- and 5-year OS was not different between the SBRT-TACE and TACE groups (98.8%, 89.1% and 80.7%, respectively vs 99.7%, 83.3% and 71.0%, respectively; P = 0.206). In multivariate analysis, the overall SBRT added to TACE did not contribute to extend PFS. However, in patients with less than 2 tumors, the combined therapy was effective (HR 0.590, 95% CI 0.392-0.889, P = 0.012). SBRT-TACE is superior to TACE in terms of LCR. Particularly, SBRT-TACE may be an effective alternative in patients with HCC number (≤2), which is not indicated for resection or local ablation.

RESUMEN

BACKGROUND/AIMS: The aim of this study was to evaluate the characteristics of cryptogenic and biliary pyogenic liver abscess by comparing the clinical aspects between the two groups. METHODS: Of 119 patients treated for pyogenic liver abscess from 2000 to 2004, 82 subjects with cryptogenic liver abscess and 21 with biliary abscess were analysed retrospectively. RESULTS: There were no significant differences between the two groups regarding clinical symptoms. The characteristics of abscess were similar except the size of abscess. The size of abscess less than 5 cm in diameter was more common in biliary group than in cryptogenic group (p=0.004). Compare to cryptogenic group, biliary group had more positive culture test from abscess (100% vs. 69%, p=0.006). Especially, E. coli isolated from abscess culture (28% vs. 7%, p=0.014) and blood culture (23% vs. 4%, p=0.035) were more common in biliary group than in cryptogenic group. There was no difference in mortality between the two groups (biliary vs. cryptogenic: 4.8% vs. 0%, p=0.204). However, the rate of clinical improvement was higher in cryptogenic group than in biliary group (92.7% vs. 66.7%, p=0.001). CONCLUSIONS: Biliary liver abscess had similar clinical characteristics to cryptogenic origin. Biliary liver abscess had smaller abscess size and more positive abscess culture rates than cryptogenic abscess. Improvement rate without complication and recurrence was higher in cryptogenic group than biliary group.

RESUMEN

Fitz-Hugh-Curtis syndrome, a kind of perihepatitis, occurs approximately in 3 to 10 percent of patients with pelvic inflammatory disease. It is not easy to detect in clinical settings due to requirement of invasive methods for diagnosis, for example, like a laparoscopic examination. Now, it has become possible to recognize it easily with the aid of non-invasive methods including an abdominal dynamic CT scan and laboratory tests. Moreover, it can be improved after the oral administration of antibiotics. Therefore, noninvasive diagnosis is desirable. Herein, clinical characteristics of ten cases of Fitz-Hugh-Curtis syndrome are reported, with a review of the literature.

RESUMEN

BACKGROUND AND AIMS: While several case reports on ischemic colitis (IC) suggest the presence of predisposing causative factors, a few studies have investigated the predisposing factors in IC. This study aimed to identify the characteristics of patients with IC, particularly focusing on the predisposing factors. METHODS: We conducted a single-center, retrospective analysis of 159 patients with IC. Clinical characteristics, laboratory data, endoscopic findings, and medical records were reviewed. Data were compared between groups of patients defined according to the predisposing factors. The predisposing factors are defined as temporary states or episodic events occurring within a week before the development of IC such as colonoscopy, enema, use of laxatives, heavy drinking, pancreatitis, shock, and burn. RESULTS: Compared to the group of patients without predisposing factors of IC, the group of patients with predisposing factors was characterized by a relatively higher prevalence of male sex (56.9% versus 33.3%, p = 0.005), younger age (60.9 ± 15.4 versus 67.2 ± 13.4 years, p = 0.010), lower incidence of hypertension (43.1% versus 60.2%, p = 0.044), and fewer risk factors (1.24 ± 1.18 versus 1.82 ± 1.22, p = 0.005). CONCLUSIONS: Among men with predisposing factors, IC may develop even at a relatively younger age and in the absence of multiple risk factors, suggesting that predisposing factors may be involved in the pathogenesis of IC.

RESUMEN

BACKGROUND/AIMS: The diagnostic efficacy of current tissue sampling techniques for gastric subepithelial tumors (SETs) is limited. Better tissue sampling techniques are needed to improve pathological diagnosis. The aim of this study was to evaluate the safety and efficacy of a new technique, mucosal incision and forceps biopsy, for reliable tissue sampling of gastric SETs. METHODS: This study enrolled 12 consecutive patients who underwent mucosal incision and forceps biopsy of gastric SETs between November 2011 and September 2014 at Gangneung Asan Hospital. The medical records of patients were reviewed retrospectively. The safety and diagnostic yield of this method were evaluated. RESULTS: By performing mucosal incision and forceps biopsy, we were able to provide a definitive histological diagnosis for 11 out of 12 cases. The pathological diagnoses were leiomyoma (3/11), gastrointestinal stromal tumor (GIST; 2/11), lipoma (2/11), schwannoma (1/11), and ectopic pancreas (3/11). In cases of leiomyoma (n=3) and GIST (n=2), tissue samples were of sufficient size to allow immunohistochemical staining. In addition, the mitotic index was evaluated in two cases of GIST. There were no procedure-related complications. CONCLUSIONS: Mucosal incision and forceps biopsy can be used as one of several methods to obtain adequate tissue samples from gastric SETs.

RESUMEN

AIM: To compare the efficacy of fixed-time split dose and split dose of an oral sodium picosulfate for bowel preparation. METHODS: This is study was prospective, randomized controlled study performed at a single Institution (2013-058). A total of 204 subjects were assigned to receive one of two sodium picosulfate regimens (i.e., fixed-time split or split) prior to colonoscopy. Main outcome measurements were bowel preparation quality and subject tolerability. RESULTS: There was no statistical difference between the fixed-time split dose regimen group and the split dose regimen group (Ottawa score mean 2.57 ± 1.91 vs 2.80 ± 2.51, P = 0.457). Cecal intubation time and physician's satisfaction of inspection were not significantly different between the two groups (P = 0.428, P = 0.489). On subgroup analysis, for afternoon procedures, the fixed-time split dose regimen was equally effective as compared with the split dose regimen (Ottawa score mean 2.56 ± 1.78 vs 2.59 ± 2.27, P = 0.932). There was no difference in tolerability or compliance between the two groups. Nausea was 21.2% in the fixed-time split dose group and 14.3% in the split dose group (P = 0.136). Vomiting was 7.1% and 2.9% (P = 0.164), abdominal discomfort 7.1% and 4.8% (P = 0.484), dizziness 1% and 4.8% (P = 0.113), cold sweating 1% and 0% (P = 0.302) and palpitation 0% and 1% (P = 0.330), respectively. Sleep disturbance was two (2%) patients in the fixed-time split dose group and zero (0%) patient in the split dose preparation (P = 0.143) group. CONCLUSION: A fixed-time split dose regimen with sodium picosulfate is not inferior to a split dose regimen for bowel preparation and equally effective for afternoon colonoscopy.

RESUMEN

There are previous reports of the identification of radiopaque medications on abdominal X-rays or computed tomography (CT). We describe an interesting case of the incidental identification of a radiopaque medication on cervical spinal CT following cervical spinal surgery. A sixty seven-year-old male patient with Parkinson's disease (PD) visited our emergency center with a C5-6 dislocation and fracture. Surgery was performed with open reduction and pedicle screw fixation through the posterior approach. No abnormal events occurred during the perioperative period. However, a radiopaque incidental foreign body in front of the C6 vertebrae was found on a cervical spinal CT and X-rays that were performed as routine examinations on postoperative day 3. After 6 hours, we performed gastrofibroscopy (GFS) but were unable to find anything. Therefore, we checked all of his medications related to the neck and check X-ray again. One enteric-coated pill he had taken exhibited strong radiodensity. Although our patient underwent an unnecessary GFS, every spinal surgeon should keep in mind that radiopaque pills can appear similar to spinal instruments on X-ray and CT. In addition, we should also know the associated dysphagia is a possible cause of the delayed passage of medicine in PD with or without cervical osteophytes.

RESUMEN

The Japanese Classification of Gastric Carcinoma histologically classifies endoscopically resected gastric cancer into differentiated and undifferentiated types according to the presence or absence of tubular structures on histology. The former includes papillary adenocarcinoma and tubular types, and the latter includes poorly differentiated adenocarcinoma, signet ring cell carcinoma and mucinous adenocarcinoma. However, gastric cancer sometimes contains a mixture of differentiated and undifferentiated components, and the clinical outcomes of the histological mixture are unknown, especially following endoscopic resection of early gastric cancer (EGC). This case was within the guideline indications for endoscopic submucosal resection (ESD), although it contained a partly signet ring cell carcinoma component; it recurred after 19 months with multiple lymph node and liver metastases. This case shows that additional surgical resection after ESD should be performed for patients with any mixed signet ring cell component, even in mild or moderately differentiated EGC.

RESUMEN

Anastomotic stenosis of the colon is not an uncommon finding; however, its frequency varies from one study to another. Traditionally, postoperative colonic stenosis is managed surgically. However, endoscopic therapy has recently become the preferred treatment modality over traditional surgery. Good short-term success has been achieved with use of endoscopic balloon dilation; however, restenosis may occur over time in 14% to 25% of patients. The current report showed the effectiveness and usefulness of an insulated-tip knife (IT-knife) for electrocautery therapy of a patient with symptomatic anastomotic colonic stenosis.

RESUMEN

Diverticulitis is the most common clinical complication of diverticular disease, affecting 10-25% of the patients with diverticula. The prevalences of diverticulitis and colon cancer tend to increase with age and are higher in industrialized countries. Consequently, diverticulitis and colon cancer have been reported to have similar epidemiological characteristics. However, the relationship between these diseases remains controversial, as is the performance of routine colonoscopy after an episode of diverticulitis to exclude colon cancer. Recently, we experienced three cases of colon cancer after treating acute diverticulitis, based on which we suggest the importance of follow-up colonoscopy after acute diverticulitis.

RESUMEN

A gastric inverted hyperplastic polyp is a rare type of gastric polyp and is characterized by downward growth of a variety of mucosal components into the submucosa. The polyp consists of columnar cells resembling foveolar epithelium and pyloric gland epithelium and can coexist with gastritis cystica profunda. Frequently, adenocarcinoma can coexist, but the relation is not clear. A 77-year-old male underwent endoscopic submucosal dissection due to early gastric cancer. A gastric inverted hyperplastic polyp was found in the removed specimen and gastric cystica profunda was also found. We report a case of gastric inverted hyperplastic polyp coexisting with gastric cystica profunda and gastric adenocarcinoma.
