ABSTRACT

Achalasia is an esophageal motility disorder characterized by loss of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter. Patients with achalasia often complain of persistent symptoms for several years before diagnosis. On the other hand, achalasia diagnosed as a sudden esophageal food impaction is uncommon, and no report has been issued on the diagnosis and successful treatment of achalasia in a 95-year-old patient. We report a case of achalasia diagnosed by high-resolution esophageal manometry and timed barium esophagography after food material removal by endoscopy in a 95-year-old woman who visited the hospital due to sudden esophageal food impaction and was successfully treated by endoscopic balloon dilatation.

ABSTRACT

Background/Aims@#The efficacy of concurrent chemoradiotherapy (CCRT) or esophagectomy for locally advanced esophageal squamous cell carcinoma (ESCC) is unclear. This study compared the survival and recurrence of patients with locally advanced ESCC after definitive CCRT and surgery. @*Methods@#A retrospective study was conducted on patients with locally advanced ESCC who underwent CCRT or esophagectomy at Kosin University Gospel Hospital from January 2010 to December 2016. The patients’ baseline characteristics, pathology, recurrence rate, and three-year/five-year overall survival were obtained Results: This study evaluated ESCC patients with cT1-T2, N+ or cT3-T4, or N, who were treated by definitive CCRT (n=14) or esophagectomy (n=32). No significant difference was noted between the two groups, except for the location of the cancer and performance state. The respective three- and five-year overall survival rates were 30.8% and 23.1% in the CCRT group and 40.2% and 22.5% in the esophagectomy group (p=0.685). In the CCRT group, three patients (21.4%) had a complete response, and two (66.7%) had a recurrence. In the esophagectomy group, an R0 resection was achieved in 28 (87.5%) patients, and a recurrence occurred in 18 (64.3%). The median disease-free survival in the CCRT and esophagectomy groups was 14 and 17 months, respectively (p=0.882). @*Conclusions@#These results showed no significant difference in survival between the definitive CCRT and surgery as the initial treatment. Nevertheless, larger prospective studies will be needed because of the retrospective nature and small number of patients in this study.

ABSTRACT

Objectives@#Few studies have reported long-term follow-up after treatment of gastric mucosaassociated lymphoid tissue (MALT) lymphoma. In this single-center study, we investigated longterm treatment outcomes in patients diagnosed with gastric MALT lymphoma. @*Methods@#The study included 80 patients diagnosed with gastric MALT lymphoma, who were followed up at a single center between January 2005 and December 2019 after Helicobacter pylori eradication therapy, radiotherapy, or chemotherapy. We evaluated complete remission, improvement, or recurrence of the lesion. Follow-up over >60 months was classified as long-term follow-up, and the progression-free survival rate was recorded. @*Results@#Following H. pylori eradication treatment, complete remission occurred in 85.9% (55/64) of H. pylori-positive and 50.0% (3/6) of H. pylori-negative patients. All patients with gastric MALT lymphoma who did not respond to H. pylori eradication therapy (100.0% [6/6]) achieved complete remission following administration of local radiotherapy. We observed no deaths on long-term follow-up (>60 months), and the progression-free survival was 101 months. @*Conclusions@#In this study, patients with gastric MALT lymphoma showed excellent survival rates, progression-free survival, and prognosis on long-term follow-up. Prospective studies are warranted to determine the long-term prognosis of gastric MALT lymphoma after treatment.

ABSTRACT

Colorectal strictures are uncommon in patients with ulcerative colitis (UC). An extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma is rarely involved in the colon but may be associated with inflammatory bowel diseases. A 41-year-old female with a six-year history of UC presented with a severe stricture of the sigmoid colon that prevented the passage of a colonoscope. A histological examination revealed non-specific inflammation and fibrosis without dysplasia or cancer.Despite conventional treatment, including mesalazine and azathioprine for one year after that visit, the stricture persisted. In addition, diffuse, edematous exudative inflammation and multiple shallow ulcers were observed in the distal rectum, revealing a MALT lymphoma testing positive for CD20, CD43, CD5, and Bcl-2, but negative for CD3, CD10, CD23, and cyclin-D1. Four weekly doses of rituximab were administered. Follow-up colonoscopy performed one month after treatment revealed slight improvement in the rectal lesion without remnant histological evidence of a MALT lymphoma. In addition, the stricture showed marked improvement, and the colonoscope could pass easily through the stricture site. This is the first case report on an improvement of a severe sigmoid colon stricture in a patient with UC after rituximab treatment for a concomitant rectal MALT lymphoma.

ABSTRACT

Achalasia, a rare motility disorder of the esophagus, is generally accepted as a premalignant disorder. This paper presents the case of a 72-year-old male with achalasia and synchronous superficial esophageal cancer who experienced dysphagia symptoms for five years. As achalasia is associated with an increased risk of esophageal cancer, both can be treated simultaneously if detected at the time of diagnosis. Achalasia and synchronous esophageal cancer are rarely detected and treated endoscopically. This paper reports a case of concurrent successful treatment.

ABSTRACT

Background/Aims@#This study aimed to develop a rehabilitation program for musculoskeletal pain experienced by gastrointestinal endoscopists and to investigate its usefulness. @*Methods@#This was a multicenter cohort study. During the first 2 weeks, a questionnaire regarding daily workload and musculoskeletal symptoms was administered. Then, a rehabilitation program including equipment/posture correction and stretching was conducted during the remaining 6 weeks. Follow-up daily workload and musculoskeletal symptom surveys were distributed during the last 2 weeks. The program satisfaction survey was performed at the 6th and 8th weeks. @*Results@#Among 118 participants (69 men), 94% (n=111) complained of musculoskeletal pain at baseline. Various hospital activities at baseline were associated with multisite musculoskeletal pain, whereas only a few workloads were correlated with musculoskeletal pain after the rehabilitation program. Follow-up musculoskeletal pain was negatively correlated with equipment/ posture program performance; arm/elbow pain was negatively correlated with elbow (R=–0.307) and wrist (R=–0.205) posture; leg/foot pain was negatively correlated with monitor position, shoulder, elbow, wrist, leg, and foot posture. Higher performance in the scope position (86.8% in the improvement vs 71.3% in the aggravation group, p=0.054) and table height (94.1% vs 79.1%, p=0.054) were associated with pain improvement. An increased number of colonoscopy procedures (6.27 in the aggravation vs 0.02 in the improvement group, p=0.017) was associated with pain aggravation. Most participants reported being average (32%) or satisfied (67%) with the program at the end of the study. @*Conclusions@#Our rehabilitation program is easily applicable, satisfactory, and helpful for improving the musculoskeletal pain experienced by gastrointestinal endoscopists.

ABSTRACT

Background@#Current evidence support that the gut microbiota plays a potential role in obesity. Bariatric surgery can reduce excess weight and decrease the risk of life-threatening weight-related health problems and may also influence gut microbiota. In this study, we aimed to investigate the changes in gut microbiota before and after bariatric surgery and evaluate the association of the gut microbial shift and altered body mass index (BMI) after bariatric surgery. @*Methods@#Between January 2019 and July 2020, stools from 58 patients scheduled for bariatric surgery were collected. Six months after bariatric surgery, stools from 22 of these patients were re-collected, and the changes in gut microbiota before and after bariatric surgery were evaluated. In addition, the differences in gut microbiota between patients with severe obesity (BMI >35 kg/m2, n=42) and healthy volunteers with normal BMI (18.8 to 22.8 kg/m2, n=41) were investigated. @*Results@#The gut microbiota of patients who underwent bariatric surgery showed increased α-diversity and differed β-diversity compared with those before surgery. Interestingly, Blautia was decreased and Bacteriodes was increased at the genus level after bariatric surgery. Further, the Blautia/Bacteroides ratio showed a positive correlation with BMI. To validate these results, we compared the gut microbiota from severely obese patients with high BMI with those from healthy volunteers and demonstrated that the Blautia/Bacteroides ratio correlated positively with BMI. @*Conclusion@#In the gut microbial analysis of patients who underwent bariatric surgery, we presented that the Blautia/Bacteroides ratio had changed after bariatric surgery and showed a positive correlation with BMI.

ABSTRACT

Background@#Radiotherapy improves overall survival in patients with abdominopelvic malignancies. However, the toxic effects of radiation restrict the maximum dose that can be given, and there are no well-established preventive or therapeutic strategies. This study was conducted to evaluate whether rebamipide, sucralfate, and rifaximin have a suppressive effect on acute ionizing radiation (IR)-induced inflammation in the intestines of mice. @*Methods@#Thirty-six ICR mice were divided into a vehicle-treated group with sham irradiation; a vehicle-treated group with irradiation; rebamipide, sucralfate, or rifaximin-treated groups with irradiation; and a rebamipide-treated group with sham irradiation. The expression of proinflammatory, anti-inflammatory, proapoptotic, and antiapoptotic factors was investigated. @*Results@#The downregulated expression of nicotinamide phosphoribosyltransferase by IR was attenuated by all drugs (p<0.05). All drugs suppressed the IR-induced activation of NF-κB and phosphorylation of MAPKs (p<0.05) and attenuated the production of TNF-α, IL-1β, and IL-6 in response to IR (p<0.05). The administration of all drugs markedly attenuated IR-induced increases in iNOS, COX-2, and PGE2 (p<0.05), as well as [Ca2+] oscillations that were increased by IR. The expression of proapoptotic genes and antiapoptotic genes was suppressed and induced, respectively, by all drugs. IR treatment increased the release of cytochrome C, which was attenuated by all drugs (p<0.05). All drug treatments resulted in a significant decrease in the expression of caspase-3 and caspase-7 (p<0.05), which were both upregulated following IR treatment. @*Conclusions@#The administration of rebamipide, sucralfate, or rifaximin prior to radiation therapy may prevent or attenuate acute radiation-induced enterocolitis.

ABSTRACT

Background/Aims@#Helicobacter pylori infection is presumably associated with iron deficiency and iron deficiency anemia (IDA). This study aimed to evaluate the relationship between H. pylori infection and the decline in iron stores in non-elderly adults during their health check-ups. @*Methods@#We identified a total of 1,069 subjects who were tested for iron, ferritin, and total iron-binding capacity during their health check-ups, from January 2016 to May 2017. Of these, subjects who underwent endoscopy via rapid urease test and those aged 65 years or below were finally enrolled. @*Results@#Overall, 281 subjects were enrolled, and 187 patients (66.5%) tested positive for H. pylori. The mean age was 36.1 years (range, 22 to 65), and 176 subjects (62.6%) were male. The mean levels of hemoglobin (14.1 ± 1.7 g/dL vs. 14.6 ± 1.4 g/dL, p = 0.019) and ferritin (121.7 ± 106.9 ng/mL vs. 151.8 ± 107.8 ng/mL, p = 0.027) in the H. pylori-positive group were significantly lower than those in the H. pylori-negative group. Iron deficiency (ferritin < 30 ng/mL) was more common in patients with H. pylori infection (p = 0.002). There was no significant difference in anemia (hemoglobin < 13 g/dL in men, < 12 g/dL in women) or IDA (anemia, ferritin < 10 ng/mL, and transferrin saturation < 16%) with H. pylori. Logistic regression analysis demonstrated that female sex (odds ratio, 197.559; 95% confidence interval, 26.461 to 1,475.015) and H. pylori infection (odds ratio, 3.033; 95% confidence interval, 1.216 to 7.567) were factors associated with iron deficiency. @*Conclusions@#H. pylori infection is associated with iron deficiency, suggesting a decline in iron stores among infected non-elderly adults.

ABSTRACT

Background/Aims@#The mucoprotective drug rebamipide is used to treat gastritis and peptic ulcers. We compared the efficacy of Mucosta Ⓡ (rebamipide 100 mg) and its new formulation, AD-203 (rebamipide 150 mg), in treating erosive gastritis. @*Methods@#This double-blind, active control, noninferiority, multicenter, phase 3 clinical trial randomly assigned 475 patients with endoscopically proven erosive gastritis to two groups: AD-203 twice daily or Mucosta Ⓡ thrice daily for 2 weeks. The intention-to-treat (ITT) analysis included 454 patients (AD-203, n=229; Mucosta Ⓡ , n=225), and the per-protocol (PP) analysis included 439 patients (AD-203, n=224; Mucosta Ⓡ , n=215). The posttreatment assessments included the primary (erosion improvement rate) and secondary endpoints (erosion and edema cure rates; improvement rates of redness, hemorrhage, and gastrointestinal symptoms). Drug-related adverse events were evaluated. @*Results@#According to the ITT analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.7% and 43.8%, respectively. According to the PP analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.3% and 43.7%, respectively. The one-sided 97.5% lower limit for the improvement rate difference between the study groups was −4.01% (95% confidence interval [CI], –13.09% to 5.06%) in the ITT analysis and −4.44% (95% CI, –13.65% to 4.78%) in the PP analysis. The groups did not significantly differ in the secondary endpoints in either analysis. Twenty-four AD-203-treated and 20 Mucosta Ⓡ -treated patients reported adverse events but no serious adverse drug reactions; both groups presented similar adverse event rates. @*Conclusions@#The new formulation of rebamipide 150 mg (AD-203) twice daily was not inferior to rebamipide 100 mg (Mucosta Ⓡ ) thrice daily. Both formulations showed a similar efficacy in treating erosive gastritis.

ABSTRACT

Background/Aims@#Minor complications that might occur after colonoscopy, including abdominal discomfort, bloating, diarrhea, and constipation, could a barrier for patients to undergo a screening colonoscopy. In this study, we aimed to identify the effect of gut microbial diversity and composition on minor complications after colonoscopy. @*Methods@#A total of 24 healthy subjects provided their stools before bowel preparation and on the 7th and 28th day after colonoscopy. On the 7th day after colonoscopy, the presence of minor complications was investigated using a questionnaire. We divided patients into 2 groups, the no complication group and complications group. The fecal microbial diversity, distribution, and composition were then compared between the groups. @*Results@#Five of the 24 subjects reported that they had undergone minor complications after colonoscopy. Most of the symptoms were mild and self-limited, but 1 patient needed medication. Interestingly, the Firmicutes/Bacteroidetes ratio of the initial stool samples before bowel preparation in the complication group was significantly higher than that in no complication group. After bowel preparation, the Firmicutes/Bacteroidetes ratio of the complication group decreased, but not in the no complication group. The microbial diversity of the no complication group decreased after bowel preparation, but not in the complication group. @*Conclusions@#The gut microbial composition and diversity before and after bowel preparation could be considered as one of the causes of minor complications after colonoscopy. Further studies are needed to delineate the role of gut microbiota in the occurrence of minor complications after colonoscopy.

ABSTRACT

Background/Aims@#Escherichia coli Nissle 1917 (EcN) alone therapy is as effective as mesalamine in inducing and maintaining remission in ulcerative colitis (UC). The efficacy and safety of EcN in combination with standard therapies have not been studied.This study examined the changes in the inflammation markers and symptoms following the additional administration of EcN to patients showing the clinical remission of UC. @*Methods@#UC patients who received EcN after being in clinical remission for more than 3 months at Kosin University Gospel Hospital between 2013 and 2018 were evaluated through the retrospective medical-record-based review. The partial Mayo score, fecal calprotectin (FC), BMI, hemoglobin, serum cholesterol, serum albumin levels, and the safety profiles were examined at 3rd and 6th months after initiating EcN. @*Results@#Ninety-four patients were included. After 3 months of treatment, there was no significant change in FC (156.3 μg/g to 141.1 μg/g) (p=0.653). On the other hand, partial Mayo score decreased significantly from 0.085 to 0.014 (p=0.025), and the bodyweight (p=0.001), BMI (p<0.001), hemoglobin (p=0.009), and cholesterol level increased (p=0.148). One patient (1.1%) experienced a serious adverse event with UC flare-up, and 14 patients (14.9%) discontinued EcN due to adverse events; all developed within 3 months. @*Conclusions@#Additional administration of EcN to clinically remission-attained UC patients may improve the UC symptoms without changing the FC levels. EcN-associated adverse events develop within the early few weeks.

ABSTRACT

Background/Aims@#This multicenter study reviewed the clinical features and prognosis according to the primary site of involvement and the treatment modality in patients with B-cell primary intestinal lymphoma (PIL). @*Methods@#Among 125 consecutive patients diagnosed with PIL, 100 patients were analyzed. @*Results@#The median age was 59 years, and the male to female ratio was 1.86:1. Diffuse large B-cell lymphoma (66/100, 66.0%) was the most common histological subtype. The estimated 5-year survival rate (5-YSR) was 48.5%. The 5-YSR was similar regardless of the type of primary treatment (chemotherapy alone vs. surgery/chemotherapy, 50.7 vs. 45.3%, p=0.582). A comparison of the survival according to the primary site of involvement revealed a 5-YSR of 32.5% (p=0.027), 64.3% (reference), 46.5% (p=0.113), and 49.8% (p=0.024) for the small intestine, ileocecal region, large intestine, and multiple sites, respectively. Multivariate analysis, however, revealed a low hemoglobin level, advanced Ann Arbor stage, and aggressive histological type to be independent prognostic factors for shorter survival but not ileocecal region involvement. @*Conclusions@#The Ann Arbor stage, hemoglobin level, and histological type were independent prognostic factors for survival, while the primary site of involvement and treatment modality did not affect the prognosis in patients with B-cell PIL.

ABSTRACT

Esophageal cancer is easy to infiltrate and metastasize because esophagus does not have serosa, and is difficult to remove it because esophagus is in the middle of the chest. Because of this, treatments of esophageal cancer do not always follow the guideline. In this situation, efforts to increase treatment efficiency and improve survival rate through multidisciplinary treatment are increasing. In this case, we report the patient with three superficial esophageal cancers (one in cervical esophagus and two in thoracic esophagus). The patient was treated with concurrent chemoradiotherapy instead of surgery through multidisciplinary discussion. The patient reached a complete remission through this discussion. This case is intended to inform the usefulness of multidisciplinary treatment in patients with esophageal cancer.

ABSTRACT

Objectives@#Since endoscopic findings of primary gastric lymphoma are ambiguous and diverse, it is not easy to distinguish them from gastric adenocarcinoma or secondary gastric lymphoma. The aim of this study was to investigate the difference in clinical and endoscopic features between primary gastric lymphoma and gastric involvement of lymphoma. @*Methods@#Forty-eight patients were enrolled in this retrospective study between June 2008 and February 2017. The patients were divided into primary gastric lymphoma group (primary group, n = 18) and gastric involvement group (secondary group, n = 30) based on whether or not they carried gastric lesions alone. Patients’ clinical characteristics, endoscopic findings and pathologic data were retrospectively reviewed based on electronic medical records. @*Results@#The mean age of patients was 63.3 ± 13.1 years and 29 patients were female (60.4%). Diffuse large B-cell lymphoma pathology (81.3%), gastric body involvement (47.9%) and ulceroinfiltrative morphology on endoscopy (43.8%) were common features. Regardless of the two groups, the initial endoscopic diagnosis was considered as lymphoma only in 41.7%. Compared with the primary group, fundus (P = 0.035) and regional lymph node (P < 0.001) were significantly associated with the secondary group. However, there was no significant difference in endoscopic findings including location, size, number, and morphology of lesion. @*Conclusions@#Endoscopic diagnosis of gastric lymphoma is a challenge. There is no difference in endoscopic findings between the primary and secondary groups even when confirmed separately. However, when the lesion is present in the fundus, we keep in mind the possibility of secondary gastric lymphoma.

ABSTRACT

Background/Aims@#Crohn’s disease (CD) is characterized by uncontrolled inflammation of the intestine. Saccharomyces Boulardii (S. boulardii), a probiotic, stabilizes the intestinal wall. This study examined the changes in the CD activity index (CDAI) after taking S. boulardii in patients with CD in clinical remission. @*Methods@#In this single hospital-based retrospective cohort study, the medical records of CD patients in clinical remission, who had received S. boulardii for more than 6 months, were reviewed. The CDAI, BMI, and serum levels of hemoglobin (Hb), ferritin, iron, vitamin B12, folate, total protein, albumin, total cholesterol, CRP, and fecal calprotectin (FC) between the initiation and the 6th month were compared. The timing and reasons for the discontinuation were also investigated. @*Results@#One hundred and fifty-four patients were included, and 92 patients, who received for more than 6 months, were analyzed. The changes in CDAI, BMI, Hb, and total cholesterol were significant as follows: CDAI from 38.52 to 30.53 (p<0.01), BMI (kg/m2 ) from 23.38 to 23.97 (p<0.01), Hb (g/dL) from 13.73 to 14.03 (p<0.01), and total cholesterol (mg/dL) from 154.9 to 161.5 (p<0.01). On the other hand, the changes in FC, CRP, ferritin, vitamin B12, folate, total protein, and albumin were not statistically significant. Only one patient stopped due to a flare-up, but this was not believed to be related to the drug. @*Conclusions@#In patients with CD in remission, S. boulardii appears to improve the CDAI, BMI, serum Hb, and total cholesterol level without safety issues. Further randomized controlled studies will be needed.
