Treatment of recurrent Clostridioides difficile infections with faecal microbiota transplantation: peri-procedural methods in a consecutive case series.

Background: Faecal microbiota transplantation (FMT) has high efficacy against recurrent Clostridioides difficile infection (CDI). Despite the increasing use of this therapy, the delay between diagnosis and treatment is excessive. Furthermore, donor selection is an important and time-consuming process. Methods: We reviewed patients who underwent FMT for recurrent CDI at the CHU Charleroi Hospital between 2015 and 2022. The general context, type of administration, adverse events, and donor selection were reported. FMT was conducted using gastroduodenoscopy, colonoscopy, and enema with either fresh or frozen material. Results: Ten patients with multiple comorbidities were treated by FMT. Seven patients were cured after one procedure. One patient was successfully cured after a change to an unrelated donor, and preliminary efficacy was established. Conclusions: FMT is an effective treatment that should be considered during the earlier phases of treatment. Stool donors should be thoroughly screened for infectious diseases and other criteria related to microbiota composition.

Isolated oesophageal Crohn's disease mimicking oesophageal carcinoma treated by Merendino procedure.

Oesophageal involvement is a very rare presentation of Crohn's disease. It can occur as an isolated mass causing dysphagia and can be mistaken for malignancy. Here, we report a case of a 75-year-old woman presenting with dysphagia and weight loss. Gastroscopy showed an ulcerating mass, and her barium swallow showed a bird beak appearance at the level of the gastro-oesophageal junction (GEJ). Repetitive biopsies were inconclusive. Fluorodeoxyglucose-positron emission tomography showed high glucose uptake (standardised uptake value: 10.2) at the level of the GEJ. Endoscopic ultrasound classified the lesion as uT3N1. Step-by-step surgical exploration revealed an oesophageal mass. A frozen section examination showed an absence of malignancy and the presence of inflammatory tissue. A partial oesophagogastrostomy was performed, and reconstruction was achieved by a Merendino procedure. Definitive histopathological examination revealed isolated oesophageal Crohn's disease.

Accuracy and other quality indicators of solid pancreatic mass endoscopic ultrasound-guided fine needle aspiration and biopsy in two academic endoscopy centers.

BACKGROUND AND AIMS: Endoscopic ultrasound fine-needle aspiration/biopsy (EUS-FNA/FNB) is highly accurate, but discrepancies between cytological and surgical diagnoses are still observed. We aimed to determine its accuracy and monitor quality indicators in our facilities. PATIENTS AND METHODS: We performed a retrospective review of all cases of pancreatic solid lesions evaluated by EUS-FNA/FNB, between July 2015 and June 2018, in two centers. Cytological and surgical findings were categorized into five groups: benign, malignant, suspect of malignancy, undetermined and insufficient for diagnosis. Final diagnosis was based on surgical diagnosis and, in patients who did not undergo surgery, on clinical outcome after 6 months follow-up. RESULTS: Altogether, 142 patients were included. FNA was the preferred tissue acquisition method (88%), with a predilection for the FNA 22G needle (57%). Cytology was insufficient for diagnosis in 2 cases, therefore a full diagnostic sample was available in 98.6% of the patients (>90%, ESGE target). Fifty-five (38.7%) patients underwent surgery. In term of cancer diagnosis, comparison with final surgical pathology (n=55) revealed 89% true positives, 5.5% true negatives, 3.6% false positives and 1.8% false negatives. When combining surgical diagnosis and clinical outcomes together, EUS-guided sampling sensitivity was 97.4% (92.5-99.5), specificity was 92.3% (74.9-99.1), positive predictive value was 98.2% (93.6- 99.5), negative predictive value was 88.9% (72.3-96.1) and accuracy was 96.4% (91.9-98.8). Post-procedural acute pancreatitis was reported in 2 patients (1.4%). CONCLUSIONS: These results reveal a performance for diagnostic tissue sampling well above the ESGE proposed target standard. Also, the uncommon high specificity illustrates the determining role of the pathologist's final interpretation and diagnosis.

BSGIE survey on COVID-19 and gastrointestinal endoscopy in Belgium : results and recommendations.

BACKGROUND AND AIMS: With the first wave of the COVID-19 pandemic declining, activities in the gastrointestinal clinic are being recommenced after a period of stringent measures. Since a second COVID-19 wave is not entirely ruled out health care professionals might remain faced with the need to perform endoscopic procedures in patients with a confirmed positive or unknown COVID-19 status. With this report we aim to provide a practical relevant overview of preparation and protective measures for gastroenterologists based on the currently available guidelines and our local experience and results of a national Belgian survey, to guarantee a fast recall of an adequate infection prevention if COVID-19 reoccurs. METHODS: From the 23rd of March 2020 and the 13th of May 2020 we performed a Pubmed, Embase and Medline search, resulting in 37 papers on COVID-19 and endoscopy. Additionally, we combined these data with data acquired from the national BSGIE survey amongst Belgian gastroenterologists. RESULTS: Based on 72 completed surveys in both university and non-university hospitals, the results show (1) a dramatic (<20%) or substantial (<50%) decrease of normal daily endoscopy in 74% and 22% of the units respectively, (2) a difference in screening and protective measures between university and non-university hospitals. These findings were subsequently compared with the current guidelines. CONCLUSION: Based on new data from the BSGIE survey and current guidelines we tried to realistically represent the current COVID-19 trends in protective measures, screening and indications for endoscopy and to provide a practical overview as preparation for a possible second wave.

Prevalence and Risk Factors of Postprandial Hypotension among Elderly People Admitted in a Geriatric Evaluation and Management Unit : An Observational Study.

OBJECTIVES: To explore the prevalence and potential risk factors of postprandial hypotension (PPH) among elderly patients in an acute geriatric ward. DESIGN: A prospective observational study. SETTING: Geriatric Unit in a Belgian tertiary-care University Hospital. PARTICIPANTS: Seventy-six hospitalized elderly patients after stabilization of their acute conditions. MEASUREMENTS: PPH and orthostatic hypotension (OH) measured by a non-invasive automated blood pressure device, demographic data, Katz's Basic Activities of Daily Living (ADL) and Lawton's instrumental ADL, Short Physical Performance Battery, Charlson Comorbidity Index, Mini Nutritional Assessment-Short Form, Timed Up and Go test, Get-up Early test, grip strength and 7 classes of drugs. RESULTS: Overall, the prevalence of PPH was 46% (n=35/76), and it was symptomatic in 31% of the patients (n=11/35). PPH is associated with OH in one-third of the cases (n=12/35). Two-thirds of the patients with HPP had a significant drop in systolic blood pressure within the first 75 minutes after a meal. In univariate analyses, risk factors of PPH were nursing home residence, alpha-blocker consumption, help needed for eating and a good level of global functional status. However, patients with a good functional status were at increased risk of alpha-blocker exposure. In multivariate analyses, only alpha-blocker consumption and help needed for eating remained statistically significant. CONCLUSION: PPH is frequent among hospitalized elderly people in a Geriatric Evaluation and Management Unit, affecting nearly one out of two people. The use of alpha-blockers is an important risk factor and may alert clinicians to the risk of PPH.

Role of up-front autologous stem-cell transplantation in peripheral T-cell lymphoma for patients in response after induction: an analysis of patients from LYSA centers.

Background: Peripheral T-cell lymphoma (PTCL) remains a therapeutic challenge. Due to the rarity and the heterogeneity of PTCL, no consensus has been achieved regarding even the type of first-line treatment. The benefit of autologous stem-cell transplantation (ASCT) is, therefore, still intensely debated. Patients and methods: In the absence of randomized trials addressing the role of ASCT, we performed a large multicentric retrospective study and used both a multivariate proportional hazard model and a propensity score matching approach to correct for sample selection bias between patients allocated or not to ASCT in intention-to-treat (ITT). Results: Among 527 patients screened from 14 centers in France, Belgium and Portugal, a final cohort of 269 patients ≤65 years old with PTCL-not otherwise specified (NOS) (N = 78, 29%), angioimmunoblastic T-cell lymphoma (AITL) (N = 123, 46%) and anaplastic lymphoma kinase-positive anaplastic large cell lymphoma (ALK-ALCL) (N = 68, 25%) with partial (N = 52, 19%) or complete responses (N = 217, 81%) after induction was identified and information about treatment allocation was carefully collected before therapy initiation from medical records. One hundred and thirty-four patients were allocated to ASCT in ITT and 135 were not. Neither the Cox multivariate model (HR = 1.02; 95% CI: 0.69-1.50 for PFS and HR = 1.08; 95% CI: 0.68-1.69 for OS) nor the propensity score analysis after stringent matching for potential confounding factors (logrank P = 0.90 and 0.66 for PFS and OS, respectively) found a survival advantage in favor of ASCT as a consolidation procedure for patients in response after induction. Subgroup analyses did not reveal any further difference for patients according to response status, stage disease or risk category. Conclusions: The present data do not support the use of ASCT for up-front consolidation for all patients with PTCL-NOS, AITL, or ALK-ALCL with partial or complete response after induction.

Gastrostomy placement : when fluoroscopy helps the endoscopist.

BACKGROUND AND STUDY AIMS: Percutaneous endoscopic gastrostomy is the most common therapeutic procedure performed by the digestive endoscopists in the upper gastrointestinal tract. It aims to feed patients presenting denutrition and/or insufficient oral intake. Percutaneous endoscopic gastrostomy feasibility is about 95-100 % although in some cases it is impossible to achieve it, leading to ask for a surgical placement. Even though the feasibility of the surgical approach is excellent its complications are quite higher than percutaneous endoscopic placement, it requires general anesthesia and sometimes these patients could be non elligible for it due to their comorbidities (malnutrition, cardio-vascular diseases etc.). Another alternative technique is the percutaneous radiological gastrostomy but this procedure is rarely available in our country. PATIENTS AND METHODS: We described four cases in patients with previous failure of PEG, in which we used an hybrid approach between radiological and endoscopic techniques, allowing the placement of gastrostomy tube, without general anesthesia. RESULTS: This was successful in all patients and there was no complication related to the procedure. CONCLUSIONS: This technique offers an additionnal opportunity to avoid general anesthesia and surgical complications in patients with unfavorable conditions.

Uncommon cause of retrosternal pain.

We present the case of a 54-year old male patient who was admitted with severe acute epigastric pain, vomiting, and inability to eat since three days before admission. After having excluded cardiac and pulmonary emergencies, an oesogastroduodenoscopy was planned and showed a gastric volvulus. The patient was treated surgically allowing gastric decompression, gastropexy and Nissen intervention. We discuss the case and describe the classification, the diagnosis, the etiologies and therapeutic options in acute and chronic gastric volvulus.

Percutaneous endoscopic jejunostomy in patients with gastroparesis following lung transplantation: feasibility and clinical outcome.

The aim of the present study was to describe success rates, complications, and outcome in patients who underwent percutaneous endoscopic jejunostomy (PEJ) because of gastroparesis due to previous lung transplantation. Between October 2008 and May 2011, 14 attempts at PEJ placement were made in 12 patients in our center. Of the 14 attempts, 11 were successful, giving a technical success rate of 78.6 %. Median duration of followup was8.5 months (2­15 months). No immediate complications were reported. Two severe complications occurred during follow up (one volvulus and one jejunocolic fistula). Jejunal nutrition was well tolerated in most of patients (9 /10). PEJ insertion is a feasible technique, which could help to provide nutritional support for patients with gastroparesis and previous lung transplantation.

Serial FDG-PET/CT for early outcome prediction in patients with metastatic colorectal cancer undergoing chemotherapy.

BACKGROUND: The study purpose was to assess the predictive value of 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET)/computerized tomography (CT) metabolic response after a single course of chemotherapy in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS: FDG-PET/CT scans were carried out at baseline and on day 14 in 41 patients with unresectable mCRC treated with a biweekly regimen of chemotherapy. Metabolic nonresponse was defined by <15% decrease in FDG uptake in the dominant proportion of the patient's lesions or if a lesion was found metabolically progressive. The PET-based response was correlated with radiological response (primary end point) and patient's outcome (secondary end points). RESULTS: RECIST response rate in metabolically responding patients was 43% (10 of 23) compared with 0% (0 of 17) in nonresponding patients (P=0.002). The metabolic assessment's predictive performance for RECIST response was sensitivity 100% [95% confidence interval (CI) 69% to 100%], specificity 57% (95% CI 37% to 75%), positive predictive value 43% (95% CI 23% to 66%), and negative predictive value 100% (95% CI 80% to 100%). Comparing metabolically responding versus nonresponding patients, the hazard ratio (HR) was 0.28 (95% CI 0.10-0.76) for overall survival and 0.57 (95% CI 0.27-1.21) for progression-free survival. CONCLUSION: The metabolic response measured by FDG-PET/CT after a single course of chemotherapy in mCRC is able to identify patients who will not benefit from the treatment.

[Is it possible to detect Staphylococcus aureus colonization or bacteriuria before orthopedic surgery hospitalization?]. / Le dépistage en ambulatoire des patients porteurs de Staphylococcus aureus ou présentant une colonisation urinaire et devant bénéficier d'une chirurgie orthopédique est-il réaliste ?

AIM OF THE STUDY: Evaluate the feasibility of Staphylococcus aureus nasal colonization and bacteriuria screening in outpatients before realizing a decolonization treatment in S. aureus carriers and a bacteriuria treatment before hospitalization. METHODS: All patients undergoing hip, knee or back surgery in which prosthesis were implanted between October 2007 until the end of June 2008 were included. Microbiological studies were performed before hospitalization. Notice for S. aureus decolonization regimen was delivered to each patient and to the general practitioner only if the patient had nasal carriage. RESULTS: Only 91.2% (240/263) of patients had microbiological results. Prevalence of S. aureus colonization was 21.4% (48 positives/224). Three patients were colonized with methicillin-resistant staphylococci. Decolonization regimen was applied before surgery to 70.8% (n=34) of the colonized patients. Among the patients, 8.9% (20/225) had bacteriuria, Escherichia coli being the most frequent micro-organism (n=16). CONCLUSION: Preoperative search and management of S. aureus colonization and of bacteriuria in outpatients is possible. Monitoring record must be performed by a member of the hospital staff.

Endoscopic treatment of postoperative enterocutaneous fistulas after bariatric surgery with the use of a fistula plug: report of five cases.

Anastomotic leaks frequently occur after bariatric surgery and their management includes different options. The present study describes the management of enterocutaneous fistulas in patients in whom surgical or endoscopic treatments have failed, by insertion of a biomaterial (Surgisis fistula plug) to facilitate healing of the gastrocutaneous fistula. Five patients with leaks after bariatric surgery were treated. All patients had undergone previous failed surgical or endoscopic attempt(s) at closure. Our technique entailed insertion of the Surgisis fistula plug into the fistula tract by a "rendezvous" procedure, via both percutaneous and endoscopic routes. The data were collected retrospectively. Initially, two patients were treated by fistula plug alone and three received fistula plug plus a self-expanding stent. In two patients, cutaneous fistula outflow ceased within a few days. The other three patients required one additional endoscopic procedure. At the end we observed healed leaks in four of the five patients (80 %). The median follow-up duration was 18 months. In conclusion, the combined therapy consisting of fistula plug implantation with optional stenting helps closure in these difficult refractory cases of gastrocutaneous fistula.
