Article Synopsis
  • Variants in the PRSS1 and PRSS2 genes are linked to chronic pancreatitis (CP), prompting research into whether a deletion variant affecting two trypsinogen pseudogenes (PRSS3P2 and TRY7) might influence CP risk.
  • A study analyzed this deletion in over 4,000 participants from different countries and found that it is associated with a protective effect against CP, especially in French, German, and Japanese populations.
  • The research suggests that the deletion enhances the function of remaining genes, leading to regulated PRSS2 expression, which could be crucial in understanding CP susceptibility.

Background: The identification of early prognostic factors during Crohn's disease (CD) remains needed for physician decision-making to minimize structural bowel damage, which this study aimed to assess in a population-based setting.

Methods: All incident cases of CD were prospectively registered from 1994 to 1997 in Brittany, a limited area of France. All charts of patients were reviewed from the diagnosis to the last clinic visit in 2015.

Our objectives were to better characterize the colorectal function of patients with Spina Bifida (SB). Patients with SB and healthy volunteers (HVs) completed prospectively a standardized questionnaire, clinical evaluation, rectal barostat, colonoscopy with biopsies and faecal collection. The data from 36 adults with SB (age: 38.

Article Synopsis
  • The study aimed to explore the incidence, outcomes, and predictors of perianal Crohn's disease (PCD) in a specific population in Brittany, France, by tracking patients from 1994 to 2015.
  • Out of 272 patients with Crohn's disease, 18.7% had PCD at diagnosis, and over time, 34% developed PCD, with risks of conditions like anal ulceration and fistulizing PCD increasing over the years.
  • The findings suggest that PCD is common in Crohn's disease and highlight the importance of targeted treatment strategies for early symptoms to prevent more severe complications like fistulizing disease.

Background And Study Aims:  The relevance of incidental colorectal focal F-FDG PET/CT uptake is debatable. All patients who were referred for colonoscopy because of incidental colonic focal FDG uptake were included in this retrospective study.

Patients And Methods:  PET/CT imaging characteristics were reviewed by a nuclear physician who was blinded to endoscopic and histopathological findings to determine the location of FDG uptake sites and to measure the maximum standardized uptake values (SUVmax) and metabolic volume (MV).

Endoscopic injections of botulinum toxin in the cardia or distal esophagus have been advocated to treat achalasia and spastic esophageal motility disorders. We conducted a retrospective study to evaluate whether manometric diagnosis using the Chicago classification in high-resolution manometry (HRM) would be predictive of the clinical response. Charts of patients with spastic and hypertensive motility disorders diagnosed with HRM and treated with botulinum toxin were retrospectively reviewed at two centers.

Background And Study Aims: A new core biopsy needle for endoscopic ultrasound (EUS)-guided sampling has recently been developed. The aim of this prospective multicenter study was to compare this needle with a standard needle in patients with solid pancreatic masses.

Patients And Methods: Consecutive patients with solid pancreatic masses referred to 17 centers for EUS-guided sampling were included.

Background: The aim of this study was to assess the efficacy and safety of pneumatic dilatation (PD) to treat symptom recurrence after Heller myotomy (HM).

Methods: Consecutive patients receiving PD for relapsing symptoms following prior HM were included in this retrospective single-center study. Eckardt score ≤3 and/or ∆ Eckardt (difference between Eckardt score before and after dilatation) ≥3 defined the success of initial dilatation.

The proportion of group D streptococcal infective endocarditis (IE) (predominantly due to Streptococcus gallolyticus) and the incidence of colorectal cancer are higher in France than in most European countries. We assumed that this could be explained by a high group D streptococci (GDS) fecal carriage rate. The aims of this study were to re-assess the GDS fecal carriage rate in France and its relationship with colorectal cancer.

Background: Endoscopic interventions are usually very challenging in patients with anatomic changes caused by earlier GI surgery. The recent development of the double-balloon enteroscopy (DBE) system creates an opportunity to reach the biliary tract and the pancreatic duct in postsurgical conditions.

Objective: To report a further application of DBE in surgical patients; namely, extraction of pancreatic stents placed in pancreaticojejunal anastomosis during pancreaticoduodenectomy.

Aim: This study was designed to ascertain the perception of patients (and their parents) followed-up for inflammatory bowel disease (IBD) concerning the transition from pediatric to adult care.

Patients And Methods: Forty-eight youths with IBD who had transited from pediatric to adult care were surveyed. Their age at transition was 17.

Little is known about the long-term results of treating gastric carcinoid tumors with a slow-release somatostatin analogue. We report three patients with type 1 and 2 gastric carcinoid tumors who were treated in the above mentioned way and followed for 27-50 months. In all cases, alternative endoscopic or surgical management was considered but deemed inappropriate.

Introduction: The risk of complications and the severity of pancreatic trauma depend on the status of the main pancreatic duct. Endoscopic retrograde pancreatography (ERCP) has emerged as the technique of reference for assessing pancreatic ductal anatomy, and it also permits therapeutic intervention by the endoscopic placement of an endoprosthesis.

Case: We report a pancreatic fistula attributable to posttraumatic rupture of the main duct, undiagnosed before ERCP and successfully treated by endoscopic stent placement.

The occurrence of associated intraperitoneal and retroperitoneal colonic perforation is uncommon after colonoscopy. We report a case of this complication revealed by subcutaneous emphysema, pneumomediastinum, pneumoperitoneum and retro-pneumoperitoneum after colonic mucosectomy.
