ABSTRACT

Gastric wall abscess, a localized form of phlegmonous gastritis, is a rare complication of endoscopic resection. We report the first case of gastric wall abscess developing after endoscopic submucosal dissection in Korea. A 72-year-old woman visited our clinic to receive treatment for gastric adenoma. The patient successfully underwent endoscopic submucosal dissection with no complications. The final diagnosis was well-differentiated tubular adenocarcinoma. We performed follow-up endoscopy 10 weeks later and found a large subepithelial lesion on the posterior wall of the gastric antrum. Abdominal computed tomography revealed hypodense wall thickening and a 5 cm heterogenous multilobular mass in the submucosal layer of the gastric antrum. Submucosal invasion with mucin-producing adenocarcinomas could therefore not be excluded. The patient agreed to undergo additional gastrectomy due to the possibility of a highly malignant lesion. The final diagnosis was acute suppurative inflammation with the formation of multiple abscesses in the mural layers and omentum. The patient was discharged with no complications.

ABSTRACT

Background@#The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors’ perceptions of the disease, and treatment patterns. @*Methods@#From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. @*Results@#A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome.Several differences were noted between the primary, secondary, and tertiary physicians’ groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. ‘The patient did not adhere to the diet’ as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and ‘There are individual differences in terms of effectiveness’ was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. @*Conclusion@#Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.

ABSTRACT

Background@#Benign esophageal strictures are treated endoscopically, often with balloon dilatation (BD) or bougie dilators. However, recurrent esophageal strictures have been reported after BD, and severe complications sometimes occur. The aim of this study was to compare the efficacy and complications of endoscopic incisional therapy (EIT) and BD for benign esophageal strictures. @*Methods@#We retrospectively reviewed patients who underwent BD or EIT as primary treatment for benign esophageal strictures between July 2014 and June 2021. Technical success was defined as restoration of the lumen diameter with <30% residual stenosis. Clinical success was defined as no recurrence of dysphagia within 1 month after BD or EIT and an increase of 1 grade or more on the Functional Oral Intake Scale. @*Results@#Thirty patients with benign esophageal stricture were enrolled. There were 16 patients in the BD group and 14 patients in the EIT group. No significant differences in technical and clinical success rates were found between the two groups. Furthermore, no significant differences in the re-stricture rate were observed between the groups. There was one complication in the EIT group and three complications in the BD group. Three patients who underwent BD had re-stricture and underwent EIT thereafter, and we regrouped patients who underwent EIT at least once. The clinical success rate was significantly higher in patients regrouped to the EIT group than in patients who underwent BD only. @*Conclusions@#EIT is not inferior to BD as the primary treatment for benign esophageal strictures, especially for recurrent cases.

ABSTRACT

Background/Aims@#Dietary factors can aggravate the symptoms of irritable bowel syndrome (IBS). Many IBS patients try restrictive diets to relieve their symptoms, but the types of diets with an exacerbating factor are unknown. Therefore, this paper reports the results of a systematic review and network meta-analysis of randomized-controlled trials (RCTs) reviewing the efficacy of food restriction diets in IBS. @*Methods@#The MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov databases were searched until July 21, 2021, to retrieve RCTs assessing the efficacy of restriction diets in adults with IBS. Two independent reviewers performed the eligibility assessment and data abstraction. RCTs that evaluated a restriction diet versus a control diet and assessed the improvement in global IBS symptoms were included. These trials reported a dichotomous assessment of the overall response to therapy. @*Results@#A total of 1,949 citations were identified. After full-text screening, 14 RCTs were considered eligible for the systematic review and network meta-analysis. A starch- and sucrose-reduced diet and a diet with low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) showed significantly better results than a usual diet. Symptom flare-ups in patients on a gluten-free diet were also significantly lower than in those on high-gluten diets. @*Conclusions@#These findings showed that the starch- and sucrose-reduced, low FODMAP, and gluten-free diets had superior effects in reducing IBS symptoms. Further studies, including head-to-head trials will be needed to establish the effectiveness of dietary restrictions on IBS symptoms.

ABSTRACT

Background/Aims@#The prevalence of eosinophilic esophagitis is increasing in Korea and there are few single-center studies regarding eosinophilic esophagitis in Korea. In particular, data about management for eosinophilic esophagitis are lacking. We aim to evaluate the practice patterns, including initial treatment and response, in the Busan city and Gyeongnam province area. @*Methods@#We retrospectively reviewed medical records to gain data on patient characteristics, medication, endoscopic images, and esophageal biopsy results. From January 2009 to December 2019, a total of 42 patients were diagnosed with eosinophilic esophagitis. @*Results@#The mean age was 50.7 (from 22 to 81) years and the cohort was predominantly male (78.6%, 33/42). The proton pump inhibitor was the preferred treatment as an initial trial for 64.3% (27/42) of patients, followed by swallowed topical steroids (16.7%, 7/42).Clinical improvement after proton pump inhibitor therapy was achieved in 88.9% (24/27) of patients. Two patients who did not achieve improvement showed a clinical and endoscopic response after swallowed topical steroids treatment. No patient received diet elimination or balloon dilatation therapy. @*Conclusions@#The treatment response of eosinophilic esophagitis was good in Busan city and Gyeongnam province area in Korea. Proton pump inhibitor therapy was the preferred and most effective treatment for eosinophilic esophagitis as the initial therapy.

ABSTRACT

Background/Aims@#Prokinetics such as mosapride citrate CR (conventional-release; Gasmotin) are commonly used in functional dyspepsia (FD). This study aims to evaluate the efficacy and safety of once-a-day mosapride citrate SR (DWJ1252), a sustained-release formulation of mosapride citrate, compared with mosapride citrate CR 3 times a day, in patients with FD. @*Methods@#In this multicenter, randomized, double-blind, active-controlled, non-inferiority study, 119 patients with FD (by the Rome III criteria, 60 for mosapride citrate SR and 59 for mosapride citrate CR) were randomly allocated to mosapride citrate SR once daily or mosapride citrate CR thrice daily for 4 weeks in 16 medical institutions. Primary end point was the change in gastrointestinal symptom (GIS) score from baseline, assessed by GIS questionnaires on 5-point Likert scale after 4-week treatment. Secondary end points and safety profiles were also analyzed. @*Results@#The study included 51 and 49 subjects in the mosapride citrate SR and mosapride citrate CR groups, respectively. GIS scores at week 4 were significantly reduced in both groups (mean ± SD: − 10.04 ± 4.45 and − 10.86 ± 5.53 in the mosapride citrate SR and mosapride citrate CR groups, respectively; P < 0.001), and the GIS changes from baseline did not differ between the 2 groups (difference, 0.82 point; 95% CI, − 1.17, 2.81; P = 0.643). Changes in GIS at weeks 2 and 4 and quality of life at week 4, and the improvement rates of global assessments at weeks 2 and 4, did not differ between the groups. Adverse events were similar in the 2 groups, and there were no serious adverse events. @*Conclusion@#In patients with FD, mosapride citrate SR once daily is as effective as mosapride citrate CR thrice daily, with a similar safety profile.

ABSTRACT

Peptic ulcer disease is common and can be diagnosed easily if the patient has an ulcer history or characteristic abdominal symptoms. On the other hand, it may take a long time for the patient to visit the hospital due to severe complications if the patient is old or insensitive to symptoms caused by peptic ulcers. In the present case, a 72-year-old female visited the hospital due to general weakness and inadequate oral intake, which started two weeks ago. Endoscopy and abdominal CT revealed huge gastric ulcer findings. Through a tissue examination by endoscopy, hepatic cells were identified, and the patient was diagnosed with peptic ulcer perforation to the liver and later received surgical treatment.

ABSTRACT

Duodenal varices are a serious complication of portal hypertension. Bleeding from duodenal varices is rare, but when bleeding does occur, it is massive and can be fatal. Unfortunately, the optimal therapeutic modality for duodenal variceal bleeding is unclear. This paper presents a patient with duodenal variceal bleeding that was managed successfully using percutaneous trans-splenic variceal obliteration (PTVO). A 56-year-old man with a history of alcoholic cirrhosis presented with a 6-day history of melena. Emergency esophagogastroduodenoscopy revealed a large, bluish mass with a nipple sign in the second portion of the duodenum. Coil embolization of the duodenal varix was performed via a trans-splenic approach (i.e., PTVO). The patient no longer complained of melena after treatment. The duodenal varix was no longer visible at the follow-up esophagogastroduodenoscopy performed three months after PTVO. The use of PTVO might be a viable option for the treatment of duodenal variceal bleeding.

ABSTRACT

Helicobacter pylori (H. pylori) is a Gram-negative spiral bacterium, classified as a group 1 carcinogen by the World Health Organization. H. pylori infection is a major cause of gastritis, gastric and duodenal ulcers, and gastric cancer. It is associated with the pathogenesis of several hematologic diseases. H. pylori eradication has been proven effective in gastric mucosa-associated lymphoid tissue lymphoma and primary immune thrombocytopenia. As H. pylori causes iron deficiency anemia via several mechanisms, some recent guidelines recommended its eradication from patients with iron deficiency anemia. There are discussions of other conditions that are not included in the international consensus and management guides on H. pylori, including monoclonal gammopathy, myelodysplastic syndrome, childhood leukemia, coagulation disorder, megaloblastic anemia, pernicious anemia, plasma cell dyscrasia, and Henoch-Schönlein purpura. Further studies are required to establish new strategies to improve the management of patients with an infection combined with a hematologic disease of controversial or peculiar association.

ABSTRACT

Primary malignant melanoma (PMM) of the gastrointestinal tract is rare. Reported cases of PMM of the lower gastrointestinal tract typically describe anal and rectal involvement rather than colonic lesions. This report describes a rare case of a 50-year-old woman with PMM originating in the colon. The patient presented to Inje University Busan Paik Hospital with a 3-day history of blood-tinged stools. She underwent colonoscopy for a diagnosis of hematochezia. The colonoscopic examination revealed a large-sized semi-pedunculated sigmoid colon polyp with a reddish-colored mucosal surface. Endoscopic mucosal resection was performed, and the final histopathological findings were consistent with a diagnosis of malignant melanoma. Systemic work-up was performed for assessment of metastasis and to identify the primary tumor considering the high metastatic rate of gastrointestinal malignant melanoma; however, no other malignant lesion was detected. Thus, she was diagnosed with colonic PMM. She underwent laparoscopic low anterior resection and lymph node dissection and has been recurrence-free for > 2 years.

ABSTRACT

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. Its diagnosis is based on symptoms, and the Rome IV criteria are recognized as the gold diagnostic standard. The Korean Society of Neurogastroenterology and Motility (KSNM) recently updated their clinical practice guidelines for the treatment of IBS, which were last issued in 2011. In this updated edition, the KSNM defines IBS as a chronic, recurrent symptom complex that includes abdominal pain or discomfort, changes in bowel habits, and bloating for at least 6 months, which is somewhat broader than the previous definition. Four major topics have been changed in the up-dated version in-line with the results of recent studies, that is, colonoscopy; a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols; probiotics; and rifaximin. Herein, we review the 2017 revised edition of the KSNM with respect to recommended clinical practice guidelines for IBS and compare these with other guidelines.

ABSTRACT

Amyloidosis is defined as the extracellular deposition of non-branching fibrils composed of a variety of serum-protein precursors. Secondary amyloidosis is associated with several chronic inflammatory conditions, such as rheumatologic or intestinal diseases, familial Mediterranean fever, or chronic infectious diseases, such as tuberculosis. Although the association of amyloidosis with inflammatory bowel disease is known, amyloidosis secondary to ulcerative colitis (UC) is rare. A 36-year-old male patient with a 15-year history of UC presented with nausea, vomiting, and abdominal pain. He had been treated with infliximab for 6 years. At the time of admission, he had been undergoing treatment with mesalazine and adalimumab since the preceding 5 months. Esophagogastroduodenoscopy showed mucosal erythema, edema, and erosions with geographic ulcers at the 2nd and 3rd portions of the duodenum. Duodenal amyloidosis was diagnosed using polarized light microscopy and Congo red stain. Monoclonal gammopathy was not detected in serum and urine tests, while the serum free light chain assay result was not specific. An increase in plasma cells in the bone marrow was not found. Secondary amyloidosis due to UC was suspected. The symptoms were resolved after glucocorticoid therapy.

ABSTRACT

Antispasmodics are effective in reducing abdominal pain and controlling spasm. Irritable bowel syndrome (IBS) patients have characteristic key factors such as intestinal motility disorder and visceral hypersensitivity. So antispasmodics have been used in the treatment of IBS for decades. Mebeverine blocks intestinal peristalsis but are not significantly better than placebo. Alverine citrate combined with simethicone is effective treatment option in IBS. Otilonium and pinaverium bromide are poorly absorbed agents, so they have mostly local effect with minimal systemic adverse events. Phloroglucinol controls acute exacerbation of abdominal pain effectively. Tiropramide reduce abdominal discomfort without serious adverse events. Fenoverine control spasm in spastic colon but does not affect normal contraction. Trimebutine have dual actions that it inhibits hyperactive colon and activates hypomotile colon. Each drug has advantages and disadvantages. Antispasmodics are considered as the first treatment option of pain-dominant IBS.

ABSTRACT

BACKGROUND/AIMS: In spite of increased concerns about the overlaps among the various functional gastrointestinal disorders (FGIDs), studies for the overlap between constipation and other common FGIDs are rare. Therefore, we investigated the patterns of overlaps between constipation and other common FGIDs. METHODS: This study was designed as a prospective nationwide multi-center questionnaire study using Rome III questionnaires for functional dyspepsia (FD), irritable bowel syndrome (IBS), and functional constipation (FC), as well as various questionnaires about patients’ information, degree of symptoms, and quality of life. For the evaluation of gastroesophageal reflux disease (GERD), GERD-Q was used. RESULTS: From 19 centers, 759 patients with constipation were enrolled. The proportions of FC and IBS subtypes of constipation (IBS-C) were 59.4% and 40.6%, respectively. Among them, 492 (64.8%) showed no overlap. One hundred and thirty-six patients (17.9%) presented overlapping GERD, and 80 patients (10.5%) presented overlapping FD. Fifty one (6.7%) of patients were overlapped by both GERD and FD. Coincidental herniated nucleus pulposus (HNP) (P = 0.026) or pulmonary diseases (P = 0.034), reduced fiber intake (P = 0.013), and laxative use (P < 0.001) independently affected the rate of overlaps. These overlapping conditions negatively affected the constipation-associated quality of life, general quality of life, and degree of constipation. CONCLUSIONS: The overlap of GERD or FD was common in patients with constipation. Coincidental HNP or pulmonary diseases, reduced fiber intake, and laxatives use were found to be independent associated factors for overlapping common FGIDs in Korean patients with constipation.

ABSTRACT

PURPOSE: Colorectal obstruction develops most frequently by carcinoma, and 7%–30% of these colorectal carcinomas are acute cases. The oncologic safety of self-expanding metal stent (SEMS) insertion as a bridge to surgery has not yet been established. Thus, we investigated the oncologic safety of SEMS insertion as a bridge to surgery in patients with obstructive colorectal cancer.METHODS: This retrospective had 56 patients enrolled requiring emergency management for obstructive colorectal cancer at stage II or III, who had undergone curative surgery between July 2008 and June 2011. These subjects were divided into two groups: patients who had undergone emergency surgery without SEMS insertion (non-stent group) and those who had undergone elective surgery after preoperative decompression with SEMS insertion (stent group). The two groups were compared for clinicopathologic characteristics, postoperative complications, and survival rate.RESULTS: Enterostomy was performed in 25 patients (100.0%) in the non-stent group and 1 patient (3.2%) in the stent group; laparoscopic surgery was carried out in 7 patients (28.0%) in the non-stent group and 19 patients (61.29%) in the stent group, each showing statistically significant differences. There was no statistically significant difference in postoperative complications and 5-year disease-free survival rate (72% vs. 74.19%, P=0.87, respectively).CONCLUSION: In treatment of malignant colorectal obstruction, elective operation after stent insertion had similar oncologic outcomes compared with emergency operation. Preoperative stent insertion not only lowers the incidence of enterostomy but also makes laparoscopic surgery possible, thereby enhancing patients' quality of life. Therefore, preoperative stent insertion is a useful method that may replace emergency surgery in treatment of malignant colorectal obstruction.

ABSTRACT

BACKGROUND/AIMS: This study evaluated the diagnostic efficacy of fluorine-18 fluorodeoxyglucose PET/CT (F-18 FDG PET/CT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma and examined the association between FDG avidity and the clinical factors affecting lesions. METHODS: Among the patients diagnosed with gastric MALT lymphoma, 16 who underwent a PET/CT for gastric MALT lymphoma were semi-quantitatively and qualitatively tested for FDG avidity of lesions in the stomach. Retrospectively collected data was analyzed to investigate the clinicoradiological factors and endoscopic findings between the patients with positive F-18 FDG PET/CT scans and those with negative scans. RESULTS: Eight of the 16 patients showed FDG avidity. When comparing the size of lesions in the stomach, the patients with FDG avidity had significantly larger lesions than those without (28.8 mm vs. 15.0 mm, p=0.03). The FDG-avid group has a significantly higher rate of positive CT scans than the non-avid group (75% vs. 13%, p=0.03). According to the endoscopic finding of the lesions, FDG avidity was pronounced with 75% of the protruding tumors, and 100% of the erosive-ulcerative types, which are a type of depressed tumors. CONCLUSIONS: When gastric MALT lymphoma is large, when lesions are found using abdominal CT scans, and the macroscopic appearance of a lesion is that of a protruding tumor or erosive-ulcerative type of depressed tumor, there is a high probability that such patients may have a positive F-18 FDG PET/CT scan.

ABSTRACT

BACKGROUND/AIMS: The purpose of this study is to investigate the recurrence rate of peptic ulcer disease (PUD) over a long follow-up period with PUD patients without Helicobacter pylori. METHODS: We retrospectively reviewed patients diagnosed with PUD on endoscopy and divided them into two groups: a H. pylori-negative group (HP-negative group), and a group of patients with untreated H. pylori (HP noneradicated group). We compared the recurrence rates of PUD in these two groups and analyzed the factors that affected ulcer recurrence. RESULTS: Total of nine hospitals in Korea participated, and a total of 1,761 patients were retrospectively reviewed. The HP-negative group included 553 patients, and the HP noneradicated group included 372 patients. The 5-year cumulative probabilities of PUD recurrence were 36.4% in the HP-negative group and 43.8% in the HP noneradicated group (p=0.113). The factors that were found to affect recurrence in the HP-negative group were elder, male, and comorbid chronic kidney disease. CONCLUSIONS: The 5-year cumulative probability of PUD recurrence without H. pylori infection after a long-term follow-up was 36.4% and the factors that affected recurrence were elder, male, and comorbid chronic kidney disease.

ABSTRACT

Esophageal carcinosarcoma is a rare malignant neoplasm that is composed of both carcinomatous and sarcomatous components. A 78-year-old man with esophageal carcinosarcoma presented with dysphagia, and was treated by endoscopic resection. Although surgery is the standard treatment for esophageal carcinosarcoma, endoscopic resection is an excellent alternative when the tumor is superficial and has no metastasis.
