An Elderly Patient Developed Ulcerative Colitis after SARS-CoV-2 mRNA Vaccination: A Case Report and Review of the Literature.

An 86-year-old man presented to our hospital with symptoms of diarrhea and bloody stool, which had manifested two weeks after receiving his third severe acute respiratory syndrome coronavirus 2 mRNA vaccination. Colonoscopy revealed diffuse, rough-surfaced mucosa extending from the ascending colon to the rectum. Despite attempting probiotic treatment, the patient's condition did not improve, leading to admission. Endoscopic findings at admission worsened. Based on endoscopic and histopathological findings, the patient was diagnosed with ulcerative colitis. Corticosteroids and 5-aminosalicylic acid were administered, and the clinical symptoms improved. Subsequently, the disease worsened during steroid tapering, and filgotinib was added, leading to steroid-free remission.

Prognostic outcomes after direct percutaneous endoscopic jejunostomy in elderly patients: comparison with percutaneous endoscopic gastrostomy.

BACKGROUND AND AIMS: Direct percutaneous endoscopic jejunostomy (DPEJ) is an alternative method of enteral feeding to percutaneous endoscopic gastrostomy (PEG). Although long-term outcomes of PEG have been reported, little is known regarding the outcomes of DPEJ. METHODS: A retrospective cohort study was conducted including 115 and 651 consecutive attempts of DPEJ and PEG, respectively, in a total of 766 elderly patients between April 2004 and March 2019. Patients' clinical background, procedural and long-term outcomes, survival analysis, and cause of death were analyzed. RESULTS: Successful placement rates were 93.9% and 97.1% for DPEJ and PEG, respectively. There was no significant difference in procedure-related adverse events (AEs) between the DPEJ and PEG groups. Rates of pneumonia, vomiting, and upper GI bleeding were significantly lower, whereas those of fistula enlargement and ileus were significantly higher in the DPEJ group as long-term AEs. The median survival periods were 694 and 734 days for DPEJ and PEG, respectively, with no significant differences between the 2 groups. Multivariate analysis revealed that age 80 years old or older, C-reactive protein level of 1.0 mg/dL or higher, and the presence of diabetes were independent risk factors for mortality after DPEJ. Respiratory tract infection was the primary cause of death in both groups. CONCLUSIONS: DPEJ is considered a safe and feasible method of access for enteral feeding as well as PEG. Although the survival period after DPEJ may be expected to be as long as that with PEG, DPEJ-specific AEs should be kept in mind on long-term feeding.

Inhibitory effects of carbon dioxide insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy.

AIM: To evaluate the inhibitory effects of carbon dioxide (CO(2)) insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy (PEG). METHODS: A total of 73 consecutive patients who were undergoing PEG were enrolled in our study. After eliminating 13 patients who fitted our exclusion criteria, 60 patients were randomly assigned to either CO(2) (30 patients) or air insufflation (30 patients) groups. PEG was performed by pull-through technique after three-point fixation of the gastric wall to the abdominal wall using a gastropexy device. Arterial blood gas analysis was performed immediately before and after the procedure. Abdominal X-ray was performed at 10 min and at 24 h after PEG to assess the extent of bowel distension. Abdominal computed tomography was performed at 24 h after the procedure to detect the presence of pneumoperitoneum. The outcomes of PEG for 7 d post-procedure were also investigated. RESULTS: Among 30 patients each for the air and the CO(2) groups, PEG could not be conducted in 2 patients of the CO(2) group, thus they were excluded. Analyses of the remaining 58 patients showed that the patients' backgrounds were not significantly different between the two groups. The elevation values of arterial partial pressure of CO(2) in the air group and the CO(2) group were 2.67 mmHg and 3.32 mmHg, respectively (P = 0.408). The evaluation of bowel distension on abdominal X ray revealed a significant decrease of small bowel distension in the CO(2) group compared to the air group (P < 0.001) at 10 min and 24 h after PEG, whereas there was no significant difference in large bowel distension between the two groups. Pneumoperitoneum was observed only in the air group but not in the CO(2) group (P = 0.003). There were no obvious differences in the laboratory data and clinical outcomes after PEG between the two groups. CONCLUSION: There was no adverse event associated with CO(2) insufflation. CO(2) insufflation is considered to be safer and more comfortable for PEG patients because of the lower incidence of pneumoperitoneum and less distension of the small bowel.

Retrospective analyses of complications associated with transcutaneous replacement of percutaneous gastrostomy and jejunostomy feeding devices.

BACKGROUND: Feeding device replacement is often required for long-term maintenance after initial percutaneous endoscopic gastrostomy or jejunostomy placement. Although there are several case reports on serious complications of gastrostomy device replacement, there are few reports of an overall analysis of the complications associated with feeding device replacement. OBJECTIVE: To evaluate the frequency and variety of complications of transcutaneous replacement of feeding devices. DESIGN: A retrospective study. SETTING: Single center: Nishimino Kosei Hospital. PATIENTS: This study involved 363 consecutive patients undergoing a total of 1265 percutaneous gastrostomy or jejunostomy device replacements from March 2000 to September 2010. INTERVENTION: A new replacement device was inserted through the ostomy tract by using an obturator after traction removal of the previous device. Endoscopic treatments were performed in the cases of fistula disruption or hemorrhage. MAIN OUTCOME MEASUREMENTS: Complications and their outcomes. RESULTS: Gastrostomy and jejunostomy devices were replaced 1126 and 139 times, respectively. There were 16 complications (1.3% of total replacements) consisting of 10 cases of fistula disruption caused by misplacement of replacement devices into the peritoneal cavity, 4 cases of hemorrhage, and 1 case each of colocutaneous fistula and device breakage. Anticoagulation or antiplatelet medications were continued in all 4 hemorrhage cases but in only 27 of 347 (7.7%) complication-free cases (P < .0001). There were no replacement-related adverse events that required surgical repair. LIMITATIONS: A single center, retrospective analysis. CONCLUSION: Fistula disruption and hemorrhage were the most common complications associated with device replacement. In patients on anticoagulants, caution is necessary to avoid hemorrhage after replacement. It is also important to verify that the replaced device is located in the GI tract lumen before feeding.

[Three cases of lung cancer detected after smoking cessation].

COPD is an independent risk factor for lung cancer. There is emerging evidence that chronic inflammation may play a significant role in the pathogenesis of lung cancer as a tumor promoter. Cigarette smoke exponentially up-regulates the production of cytokines. After stopping smoking, the risk of lung cancer remains increased in patients with COPD. We report 3 patients with COPD in whom lung cancer was detected within 16 months after smoking cessation. All were outpatients of our hospital, and participated in a program for smoking cessation according to their doctor's advice. Two successfully stopped smoking, and the other was in the program for smoking cessation. It was difficult to detect lung cancers on chest X-ray films 8-11 months previously. Periodic medical examination chest X-ray films revealed lung cancers 2-16 months after smoking cessation. Heavy smokers, especially COPD patients, have a high risk of developing lung cancer at the start of smoking cessation, and therefore have a high risk of contracting lung cancer even after halting smoking. Generally, most patients do not visit hospitals for the purpose of only smoking cessation after successfully halting smoking. Nevertheless, it is necessary for previously heavy smokers, especially COPD patients, to undergo repeated careful medical examination to detect lung cancer.

[A case of cardiac sarcoidosis occurring during combination therapy by IFN alpha and ribavirin for chronic hepatitis C].

A 72-year-old woman received combination therapy with peginterferon alpha and ribavirin for treatment of chronic hepatitis C. Approximately 40 weeks after starting treatment, she developed an eruption in the left inner canthus and sarcoidosis was diagnosed after biopsy of the eruption. Combination therapy was discontinued, and further detailed examinations revealed bilateral hilar lymphadenopathy, uveitis, and complete atrioventricular block. A permanent cardiac pacemaker was implanted, and her sarcoidosis improved upon administration of corticosteroids.

Clinical investigation of upper gastrointestinal hemorrhage after percutaneous endoscopic gastrostomy.

BACKGROUND: Upper gastrointestinal (GI) hemorrhage after percutaneous endoscopic gastrostomy (PEG) is sometimes reported as one of the serious complications. Our purpose was to clarify the cause of upper GI hemorrhage after PEG. PATIENTS AND METHODS: We retrospectively investigated the causes of upper GI hemorrhage among a total of 416 patients out of 426 consecutive patients who underwent PEG in our institution, excluding 10 patients who showed upper GI tumors on PEG placement. RESULTS: Among 17 patients who developed upper GI hemorrhage after PEG, three and four patients showed PEG tube placement and replacement-related hemorrhage, respectively; these lesions were vascular or mucosal tears around the gastrostomy site. Ten patients experienced 12 episodes of upper GI hemorrhage during PEG tube feeding. The lesions showing bleeding were caused by reflux esophagitis (five patients), gastric ulcer (two patients), gastric erosion due to mucosal inclusion in the side hole of the internal bolster (two patients), and duodenal diverticular hemorrhage (one patient). Anticoagulants were administered in six patients, including four patients with replacement-related hemorrhage and one patient each with reflux esophagitis and gastric ulcer. CONCLUSIONS: Reflux esophagitis was the most frequent reason for upper GI hemorrhage after PEG. The interruption of anticoagulants should be considered for the prevention of hemorrhage on the placement as well as replacement of a gastrostomy tube.

Inhibition of gastroesophageal reflux by semi-solid nutrients in patients with percutaneous endoscopic gastrostomy.

BACKGROUND: Aspiration is one of the major complications after percutaneous endoscopic gastrostomy (PEG). The administration of semi-solid nutrients by means of gastrostomy tube has recently been reported to be effective in preventing aspiration pneumonia. The effects of semi-solid nutrients on gastroesophageal reflux, intragastric distribution, and gastric emptying were evaluated. METHODS: Semi-solid nutrients were prepared by liquid nutrients mixed with agar at the concentration of 0.5%. The distribution of the administered radiolabeled liquid and semi-solid nutrients was monitored by a scintillation camera for 15 post-PEG patients. The percentage of esophageal reflux, the distribution of the proximal and distal stomach, and the gastric emptying time were evaluated. RESULTS: The percentage of gastroesophageal reflux was significantly decreased in semi-solid nutrients (0.82 +/- 1.27%) compared with liquid nutrients (3.75 +/- 4.25%), whereas the gastric emptying time was not different. The distribution of semi-solid nutrients was not different from liquid nutrients in the early phase, whereas higher retention of liquid nutrients in the proximal stomach was observed in the late phase. CONCLUSIONS: Gastroesophageal reflux was significantly inhibited by semi-solid nutrients. One of the mechanisms of the inhibition is considered to be an improvement in the transition from the proximal to distal stomach in semi-solid nutrients.

A case of acute gastroduodenitis with cytomegalovirus infection in a healthy adult.

A 33-year-old man with epigastralgia was admitted. Upper gastrointestinal endoscopy revealed gastric fold hypertrophy, mucosal hemorrhage, and widespread erosion in the stomach and aphthoid erosion in the duodenum. The presence of intranuclear inclusion bodies positively stained with anti-cytomegalovirus antibody from the biopsy specimens indicated that the gastroduodenitis was related to cytomegalovirus (CMV) infection. He recovered within 2 weeks without antiviral therapy. Duodenal involvement of CMV infection is fairly rare in immunocompetent hosts.

Clinical analysis of gastroesophageal reflux after PEG.

BACKGROUND: It is difficult to predict whether or not gastroesophageal reflux (GER), such as aspiration or vomiting, will occur after PEG. OBJECTIVE: To identify factors that would support the prediction of aspiration after PEG. DESIGN: Case-control study. SETTING: Patients who underwent PEG from February 1998 to June 2005 in our hospital. PATIENTS: The study included 178 patients. INTERVENTIONS: Endoscopic observation was carried out during PEG tube placement and at PEG tube replacement to determine the presence of hiatus hernia and/or reflux esophagitis. MAIN OUTCOME MEASUREMENTS: Gastric emptying and GER index (GERI) were measured by using a radioisotope technique. RESULTS: The patients were divided into 2 groups: the non-GER (NGER) group (n = 108), who had no symptoms of GER, and the GER group (n = 70), who showed these symptoms. No significant differences were observed between the groups in age, sex, morbidity, the presence of reflux esophagitis at PEG tube placement, gastric emptying, or serum albumin levels. The presence of a hiatus hernia (P = .028) and reflux esophagitis grading Los Angeles classification C or D (P = .008) were significantly more frequent in the GER group compared with the NGER group. The GERI was also significantly higher in the GER group than in the NGER group (P < .0001). CONCLUSIONS: The presence of hiatus hernia, severe reflux esophagitis, and a high GERI might be predictive factors of aspiration or vomiting after PEG tube placement.
