RESUMO
BACKGROUND AND STUDY AIMS: Endoscopy Ultra-Sound (EUS)-guided fiducial marker placement in patients with esophageal or rectal cancer who have been referred for radiation therapy lacks data regarding its feasibility and safety. The aim of this study was to assess the success rate of EUS-guided fiducial marker placement in these indications. PATIENTS AND METHODS: This prospective multicenter study enrolled patients with rectal or esophageal tumor, who were treated between March 2017 and June 2021. The primary endpoint was the success of fiducial markers placement under EUS guidance utilizing the preloaded 22-gauge EchoTip Ultra Fiducial needle® (Cook Medical, Limerick, Ireland), defined by the ability to release fiducials at least at proximal and distal ends of the tumor. The secondary endpoints were the adverse events, length of procedure, and remaining fiducial markers throughout radiation therapy. RESULTS: A total of 33 patients were included in this study, with a mean age of 64.2 years ±11.3, and 66.7% of males. Twenty patients had rectal adenocarcinoma, and 13 had esophageal malignancies. The success rate of fiducial markers placement was 93.9%. Markers could only be released at the proximal end of the tumor in two cases. The average procedure time (±SD) was 12.5 min (±4.8). The number of fiducial markers placed for each patient was 3.8 (±0.5). No adverse event was reported. At the end of radiotherapy, markers were still visible on imaging in all patients. CONCLUSION: This prospective multicenter study highlights the safety and high success of the placement of fiducial markers under EUS, for rectal and esophageal tumors, without adverse event, and with a short procedure time. Fiducial markers remain in place over time during radiation therapy. CLINICALTRIALS: gov ID: NCT03057288.
RESUMO
INTRODUCTION: Catatonia is a syndrome that can present in different forms and can occur in multiple psychiatric and somatic conditions. This case report describes lethal catatonia caused by delayed toxic leukoencephalopathy after excessive use of cocaine and methadone. The characteristic radiographic imaging and biphasic course are discussed. CASE REPORT: A 54-year-old woman was presented unconsciously at the emergency department after intoxication with methadone and cocaine. After initial recovery, her condition deteriorated unexpectedly, resulting in lethal catatonia. Magnetic resonance imaging (MRI) showed hyperintense white matter abnormalities and diffusion restriction, evident for leukoencephalopathy. DISCUSSION: Catatonia can develop in multiple psychiatric and somatic diseases, including toxic leukoencephalopathy. A biphasic course and specific MRI findings are characteristics for delayed toxic leukoencephalopathy, due to intoxication with drugs.

BACKGROUND AND STUDY AIMS: Urgent endoscopy is often used to diagnose and sometimes treat acute upper gastrointestinal syndromes (hemorrhage, toxic ingestion, and occlusion). However, its suitability concerning the management of lower gastrointestinal conditions in emergency circumstances is controversial. PATIENTS AND METHODS: We studied the role of emergency colonoscopy in diagnosis and treatment of all consecutive patients presenting with acute lower gastrointestinal symptoms referred to our hospital on an emergency basis. All patients were first managed by physicians from the emergency room and/or the intensive care unit (ICU); the treatments included fluid resuscitation, blood transfusion, and antibiotic or cardiotonic as needed. Bowel cleansing was performed to purge the colon of clots, stool, and blood when clinically possible; alternatively, a bowel enema was used. Patients only underwent a computed tomography (CT) scan prior to the colonoscopy in clinically relevant situations. Colonoscopy was performed within 6â-â36 hours after hospitalization or the beginning of the clinical symptoms (hemorrhage, sepsis, colon distension) or occlusion, as assessed by abdominal CT scan. RESULTS: From 2010 to 2015, 603 patients underwent urgent colonoscopy; among them, 214 (36â%) presented with lower GI bleeding, while 264 (44â%) had symptoms suggestive of intestinal ischemia; almost half (49â%, nâ=â295) of the patients were hospitalized in the ICU. Patients received therapies, such as clips (15â%), epinephrine injections (5â%), bipolar coagulation (7â%), or devolvulation (3â%) using colonoscopy or antibiotic therapy when needed. No perforation was observed after colonoscopy and only three cases of hemorrhage recurrence were documented as complications after the procedure. Overall, 192 patients died within 1 month after colonoscopy due to four independent risk situations, as follows: septic shock, heart transplantation, multiorgan failure, and ischemic colitis. Only 67 (35â%) underwent urgent intestinal surgery when ischemic colitis was identified, and this did not have a significant effect on the mortality rate. CONCLUSIONS: Urgent bedside colonoscopy is feasible and safe for routine use. The highest advantage was observed in patients with red blood hemorrhage, diarrhea, and colon distension when symptoms were not associated with multiorgane failure, heart transplantation, or septic shock. As revealed by colonoscopy and pathological features, ischemic colitis is associated with a bad prognosis, and patients experience a higher rate of early mortality regardless of whether they undergo urgent colon surgery.
RESUMO
INTRODUCTION: Early reports of endoscopic submucosal dissection (ESD) in Europe suggested high complication rates and disappointing outcomes compared to publications from Japan. Since 2008, we have been conducting a nationwide survey to monitor the outcomes and complications of ESD over time. MATERIAL AND METHODS: All consecutive ESD cases from 14 centers in France were prospectively included in the database. Demographic, procedural, outcome and follow-up data were recorded. The results obtained over three years were compared to previously published data covering the 2008-2010 period. RESULTS: Between November 2010 and June 2013, 319 ESD cases performed in 314 patients (62% male, mean (±SD) age 65.4 ± 12) were analyzed and compared to 188 ESD cases in 188 patients (61% male, mean (±SD) age 64.6 ± 13) performed between January 2008 and October 2010. The mean (±SD) lesion size was 39 ± 12 mm in 2010-2013 vs 32.1 ± 21 for 2008-2010 (p = 0.004). En bloc resection improved from 77.1% to 91.7% (p < 0.0001) while R0 en bloc resection remained stable from 72.9% to 71.9% (p = 0.8) over time. Complication rate dropped from 29.2% between 2008 and 2010 to 14.1% between 2010 and 2013 (p < 0.0001), with bleeding decreasing from 11.2% to 4.7% (p = 0.01) and perforations from 18.1% to 8.1% (p = 0.002) over time. No procedure-related mortality was recorded. CONCLUSIONS: In this multicenter study, ESD achieved high rates of en bloc resection with a significant trend toward better outcomes over time. Improvements in lesion delineation and characterization are still needed to increase R0 resection rates.
RESUMO
Iron deficiency is common in patients with inflammatory bowel disease (IBD), but can be difficult to diagnose in the presence of inflammation because ferritin is an acute phase reactant. The transferrin receptor-ferritin index (TfR-F) has a high sensitivity and specificity for iron deficiency diagnosis in chronic diseases. The diagnostic efficacy of TfR-F is little known in patients with IBD. The aim of the study was to assess the added value of TfR-F to iron deficiency diagnosis in a prospective cohort of patients with IBD.Consecutive IBD patients were prospectively enrolled. Patients were excluded in case of blood transfusion, iron supplementation, or lack of consent. IBD activity was assessed on markers of inflammation (C-reactive protein, endoscopy, fecal calprotectin). Hemoglobin, ferritin, vitamin B9 and B12, Lactate dehydrogenase, haptoglobin, and soluble transferrin receptor (sTfR) were assayed. TfR-F was calculated as the ratio sTfR/log ferritin. Iron deficiency was defined by ferritin <30 ng/mL or TfR-F >2 in the presence of inflammation.One-hundred fifty patients with median age 38 years (16-78) and Crohn disease (n = 105), ulcerative colitis (n = 43), or unclassified colitis (n = 2) were included. Active disease was identified in 45.3%. Anemia was diagnosed in 28%. Thirty-six patients (24%) had ferritin <30 ng/mL. Thirty-two patients (21.3%) had ferritin levels from 30 to 100 ng/ml and inflammation: 2 had vitamin B12 deficiency excluding TfR-F analysis, 13 of 30 (43.3%) had TfR-F >2. Overall, iron deficiency was diagnosed in 32.7% of the patients.TfR-F in addition to ferritin <30 ng/mL criterion increased by 36% diagnosis rates of iron deficiency. TfR-F appeared as a useful biomarker that could help physicians to diagnose true iron deficiency in patients with active IBD.

AIM: To investigate the gastric emptying after bowel preparation to allow general anaesthesia. METHODS: A prospective, non-comparative, and non-randomized trial was performed and registered on Eudra CT database (2011-002953-80) and on www.trial.gov (NCT01398098). All patients had a validated indication for colonoscopy and a preparation using sodium phosphate (NaP) tablets. The day of the procedure, patients took 4 tablets with 250 mL of water every 15 min, three times. The gastric volume was estimated every 15 min from computed antral surfaces and weight according to the formula of Perlas et al (Anesthesiology, 2009). Colonoscopy was performed within the 6 h following the last intake. RESULTS: Thirty patients were prospectively included in the study from November 2011 to May 2012. The maximum volume of the antrum was 212 mL, achieved 15 min after the last intake. 24%, 67% and 92% of subjects had an antral volume below 20 mL at 60, 120 and 150 min, respectively. 81% of patients had a Boston score equal to 2 or 3 in each colonic segment. No adverse events leading to treatment discontinuation were reported. CONCLUSION: Gastric volume evaluation appeared to be a simple and reliable method for the assessment of gastric emptying. Data allow considering the NaP tablets bowel preparation in the morning of the procedure and confirming that gastric emptying is achieved after two hours, allowing general anaesthesia.

Being the second cancer for men and the third cancer for women in France, colorectal cancer represents a serious public health issue. Its incidence has increased these last years and despite new therapeutics being developed, it still has a bad prognostic. Thanks in part to Hemoccult national mass screening program, its diagnosis is made possible at an earlier stage, which makes a surgical curative resection and the carrying out of adjuvant chemotherapy possible. For stage III colic cancer that has been surgically removed, adjuvant chemotherapy by FOLFOX 4 has to be offered. Nevertheless, because of its toxicities, the patient's high age, important comorbidities or post-surgical complications, this chemotherapy occasionally cannot be done. What are the colorectal cancer prognostic factors which would guide the chemotherapy? TNM classification, number of examined lymph nodes, MSI status, and presence or not of a perforation or a perinervous, lymphatic or venous invasion is recognized prognostic factors. Also, what are the alternatives of FOLFOX 4 regimen as colorectal cancer adjuvant treatment?
