[Gastric and colic digestive localizations of myeloma; 3 case studies and literature review]. / Localisations digestives gastriques et coliques de myélomes ; étude de 3 cas et revue de la littérature.

Multiple myeloma is a malignant plasma cell proliferation located in the bone marrow and bones. It can secondarily manifest with extraosseous involvement, but the gastro-intestinal tract locations are rare. We report 3 cases of gastric and colonic localizations of myeloma in two males and one female, aged 66, 71 and 77years. Multiple myeloma had been diagnosed 1 to 7years before. Digestive symptoms were epigastric pain, rectal bleeding or an obstructive syndrome. Endoscopy revealed ulcerated and budding tumors in the stomach, and nodular pseudo-polypoid tumor formations or an ulcerated erythematous area in the colon. Histopathological examination of the biopsies showed a diffuse tumor cell proliferation in the lamina propria composed of cells with a plasmacytoid or plasmablastic appearance, expressing plasma cell markers such as CD138 on immunohistochemistry. The 3 patients died in the weeks following the diagnosis. The prognosis of digestive localizations of multiple myeloma remains very poor despite new therapies. In the presence of any digestive symptoms in these patients with multiple myeloma, more systematic endoscopy may allow an earlier diagnosis and the implementation of more effective therapies.

Endoscopic Treatment of Enterocutaneous Fistulas in Crohn's Disease.

BACKGROUND: Management of enterocutaneous fistulas in Crohn's disease is challenging. Most patients still need intestinal resection in the biologic era. OBJECTIVE: The aim of this study was to evaluate the efficacy of endoscopic treatment for enterocutaneous fistulas. DESIGN: This is a retrospective study of medical records. SETTINGS: This study was conducted in a single institution. PATIENTS: All consecutive patients with Crohn's disease with an enterocutaneous fistula who underwent endoscopic fistula closure with the use of an over-the-scope clip or a hemostatic clip were included. MAIN OUTCOME MEASURES: The main outcome measured was the clinical success 3 months after the procedure, which was defined as the complete closure of all fistulas at physical examination and complete cessation of the drainage from the external opening, without surgery. RESULTS: Eight patients (men, 25%; median age 45 years [interquartile range, 33-51]) were followed. Fistulas were localized at the ileocolonic or colocolonic anastomosis in 7 patients and at the stomach in 1 patient. Seven patients were treated with an over-the-scope clip, and one was treated with a hemostatic clip. Technical success was achieved in all cases. Clinical success at 3 months was achieved in 75% of cases (6/8 patients). After a median 16-month (interquartile range, 13-23) follow-up, 3 of 8 (37.5%) patients had enterocutaneous fistula closure and 2 of 8 (25%) needed intestinal resection. No complications were observed. LIMITATIONS: The retrospective nature, the small sample size of the study, and the heterogeneity of the population limit the interpretation of the results. CONCLUSIONS: Endoscopic treatment of enterocutaneous fistulas is feasible with a short-term effectiveness. Additional studies are needed to confirm these results.

A neural network-based algorithm for assessing the cleanliness of small bowel during capsule endoscopy.

BACKGROUND: Cleanliness scores in small-bowel capsule endoscopy (SBCE) have poor reproducibility. The aim of this study was to evaluate a neural network-based algorithm for automated assessment of small-bowel cleanliness during capsule endoscopy. METHODS: 600 normal third-generation SBCE still frames were categorized as "adequate" or "inadequate" in terms of cleanliness by three expert readers, according to a 10-point scale, and served as a training database. Then, 156 third-generation SBCE recordings were categorized in a consensual manner as "adequate" or "inadequate" in terms of cleanliness; this testing database was split into two independent 78-video subsets for the tuning and evaluation of the algorithm, respectively. RESULTS: Using a threshold of 79 % "adequate" still frames per video to achieve the best performance, the algorithm yielded a sensitivity of 90.3 %, specificity of 83.3 %, and accuracy of 89.7 %. The reproducibility was perfect. The mean calculation time per video was 3 (standard deviation 1) minutes. CONCLUSION: This neural network-based algorithm allowing automatic assessment of small-bowel cleanliness during capsule endoscopy was highly sensitive and paves the way for automated, standardized SBCE reports.

Safety and efficacy of percutaneous transhepatic-endoscopic rendezvous procedure in a single session.

PURPOSE: To demonstrate the feasibility and safety of PTE-RV performed in a single session. MATERIALS AND METHODS: This is a retrospective review of a prospective database on ERCP between January 2014 and December 2018. PTE-RV was performed in case of second ERCP failure. Technical success was defined as the establishment of an intestinal access to the biliary tract using a PTE-RV procedure allowing an immediate internal biliary drainage. Safety endpoints included intra-operative complications, morbidity and mortality occurring within 30 days after the procedure. RESULTS: Eighty-four patients (44 M/40F) with a median age of 69 years (range 40-91 years) underwent combined PTE-RV. The PTE-RVs were successfully performed in the same session in 80 subjects, resulting in an overall technical success rate of 95.2%. Adverse events were observed in 19% (16/84) of cases. The mortality rate within 30 days after the procedure was 9.5%. CONCLUSION: Percutaneous transhepatic-endoscopic rendezvous technique is feasible in a single session with acceptable level of risk. A randomized trial is required to compare EUBD and PTE-RV.

[Gastric glomus tumors. Interest of ultrasound endoscopic biopsies for the diagnosis. About two cases]. / Les tumeurs glomiques gastriques. Intérêt des biopsies sous échoendoscopie pour le diagnostic. À propos de deux cas.

Glomus tumors are rare mesenchymal tumors, mostly benign, although a few malignant cases have been described in the literature. These tumors are usually localized subcutaneously or subcutaneously, however they may exceptionally be gastric localized. We report two new observations diagnosed on biopsies performed by echo endoscopy. The first was a 66-year-old man and the second a 78-year-old man. In both cases, the lesions were on astral, nodular, and very limited location. The biopsies revealed a tumor proliferation of trabecular architecture, composed by monomorphic cells, with eosinophilic cytoplasm, medium size, with a rounded, regular nucleus, without mitosis or necrosis, with distended and branched capillaries on the periphery. In immunohistochemical studies, tumor cells expressed smooth muscle actin and caldesmone. The proliferation index KI 67 was very low. In practice, however, preoperative diagnosis remains difficult because there is no typical appearance in imaging or echo-endoscopy to distinguish them from other gastric parietal tumors. To date, there is no consensus on the therapeutic management of gastric glomus tumors. However, endoscopic resection by dissection under the mucosa associated with endoscopic monitoring seems to be a method of choice as well as a way to postpone open or laparoscopic surgery, especially when these tumors are small (<30mm).

Complete Endoscopic Healing Associated With Better Outcomes Than Partial Endoscopic Healing in Patients With Crohn's Disease.

BACKGROUND & AIMS: Mucosal healing (MH) has been associated with good outcomes of patients with Crohn's disease (CD). It is not clear what levels of endoscopic healing, based on CD endoscopic index score (CDEIS), associate with different courses of disease progression. We assessed long-term outcomes of patients with CD according to different levels of MH. METHODS: We performed a retrospective study of 84 patients with CD and MH who received biologic therapy (80% with infliximab) from 2008 through 2015 at 2 university hospitals in France and compared outcomes of patients with CD endoscopic index scores (CDEISs) of 0 vs CDEISs greater than 0 but less than 4. Patients were followed until treatment failure or through June 2016. The primary outcome measure was treatment failure, defined by the need for biologic optimization, initiation of corticosteroids, or a Harvey-Bradshaw score above 4 associated with change in treatment, CD-related hospitalization, and/or intestinal resection. RESULTS: After a median follow-up time of 4.8 years (interquartile range, 2.1-7.2), 27 patients (32%) had treatment failure and 3 patients (3.6%) underwent an intestinal resection. Rates of treatment failure were 25% in patients with a CDEIS of 0 and 48% in patients with CDEISs greater than 0 but less than 4 (P = .045). Median times to treatment failure were 21 months (interquartile range, 5-43 months) in patients with a CDEIS of 0 and 13 months (interquartile range, 3.6-35 months) in patients with CDEISs greater than 0 but less than 4 (P = .047). None of the patients with a CEDIS of 0 underwent intestinal resection whereas 11% patients with CDEISs greater than 0 but less than 4 required intestinal resection (P = .031). Patients with a CDEIS of 0 also had a significant lower rate of CD-related hospitalizations than patients with CDEISs greater than 0 but less than 4 (3.5% vs 18%; P = .013). In multivariate analysis, CDEISs greater than 0 but less than 4 (vs CDEIS = 0) was the only factor associated with treatment failure (hazard ratio, 2.6; 95% CI, 1.2-5.8; P = .02). CONCLUSIONS: Complete endoscopic healing (CDEIS = 0) is associated with better long-term outcomes than partial endoscopic healing (CDEIS = 1-4) in patients with CD, as well as fewer surgeries and hospitalizations and an overall decreased risk of treatment failure.

Per-oral endoscopic myotomy with septotomy for the treatment of distal esophageal diverticula (D-POEM).

BACKGROUND AND AIMS: Epinephric diverticula are frequently associated with esophageal motility disorder. Their management implies surgery, with 15% morbidity and 3% mortality rates. Flexible endoscopy could be an effective and safer approach for treating esophageal diverticulum with motility disorder. We report our experience of seven consecutive cases treated with per-oral endoscopic submucosal septotomy and myotomy (D-POEM). METHODS: Seven consecutive patients were referred for symptomatic non-zenker's esophageal diverticulum. The steps of the procedure were as follows: (i) analysis of the esophageal anatomy; (ii) vertical mucosal incision just above the upper edge of the diverticulum; (iii) submucosal tunneling by submucosal dissection, alongside the submucosal window of the diverticulum and the downstream septum; (iv) identification of the septum and the diverticular area; (v) diverticular septotomy followed by antegrade esocardial myotomy up to 2 cm below the cardia; and (vi) closure of the mucosal incision. RESULTS: Three men and four women aged from 62 to 90 years were treated. Four patients had a diet with adapted texture before the treatment and five patients had weight loss (4 kg to 24 kg). At preoperative evaluation, all had an esophageal motility disorder at high-resolution manometry. The procedures were successfully performed in all the patients without per-operative complications. During the 30 postoperative days, no significant adverse events occurred. Three months after treatment, six patients (85%) had clinical improvement with complete or partial regression of dysphagia. All the patients stabilized or gained weight after the treatment. CONCLUSION: The D-POEM technique is a mini-invasive effective and safe technique to treat symptoms due to both esophageal motility disorder and distal esophageal diverticula. It could be a very interesting solution for non-surgical patients in the first time that could be extended to other patients after favorable larger series.

Prospective evaluation of third-generation small bowel capsule endoscopy videos by independent readers demonstrates poor reproducibility of cleanliness classifications.

OBJECTIVE: The detection of lesions during small bowel (SB) capsule endoscopy (CE) depends on the cleanliness of the intestine. Quality reporting and comparison of different preparation methods require reliable scores. Three scores known as quantitative index (QI), qualitative evaluation (QE), and overall adequacy assessment (OAA), have been proposed to assess SB cleanliness, and are sometimes used in clinical practice and in clinical trials. However, none of these scores has received any external validation. The aim of our study was to re-assess the reproducibility of these three specific scores. METHODS: One-hundred-and-fifty-five complete third-generation SB-CE video recordings were extracted from a multicenter randomized controlled trial (PREPINTEST) which evaluated three modalities of SB preparation for CE. Three experts independently read the 155 SB-CE video recordings twice, in a random order, over 48 -h periods at 6-week intervals, using the QI, QE and OAA scores. Cohen's linearly weighted kappa coefficients were calculated to assess intra-observer and inter-observer agreements. RESULTS: Intra-observer reproducibility was fair to moderate, with kappa coefficients between 0.37 and 0.46 for QI, 0.41 and 0.51 for QE, 0.41 and 0.50 for OAA. Inter-observer reproducibility was fair to substantial according to kappa coefficients between experts varying from 0.40 to 0.64, 0.29 to 0.65, and 0.52 to 0.71, for QI, QE and OAA, respectively. CONCLUSIONS: QI, QE and OAA scores, currently used for evaluation of the quality of the preparation of SB-CE, are not sufficiently reproducible. Other scores or methods are therefore needed for SB-CE cleanliness assessment.
