Complications in Patients with Surgically Altered Gastrointestinal Anatomy Undergoing Endoscopic Retrograde Cholangiopancreatography: 15-Year Experience at a Tertiary Care Center in Latin America.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients. Our goal is to describe complications of ERCP in SAGA at a national referral institution. METHODS: Retrospective, single-center cohort study. All SAGA ERCP procedures performed at the Gastrointestinal Endoscopy Department of the National Institute of Medical Sciences and Nutrition Salvador Zubirán from January 2008 to May 2023 were included. Extracted data from records included procedure specifics, endoscope type, success, and complications. Complications were evaluated during procedure and 28-day post-procedure and classified using the AGREE system. RESULTS: A total of 266 procedures in 174 patients were included, 74% were women, and the median age was 44 years. Predominant modified anatomy was Roux-en-Y biliary reconstruction (79%), followed by Whipple procedure (13%) and subtotal gastrectomy with Roux-en-Y reconstruction (6.0%). The main indications were cholangitis with stricture (31%), stricture (19%), and cholangitis (19%). DBE was used in 89%, PE in 7.5%, and SBE in 3.4%. Success rates were 77% endoscopic, 72% technical, and 69% therapeutic; in 30%, the procedure was unsuccessful. Complications happened in 18% of cases, most commonly cholangitis (7.5%), followed by perforation (2.6%) and hemorrhage (1.9%). According to the AGREE classification, 10.9% were grades 1 and 2, 6.4% were grade 3, and 0.4% were grade 4 complications. No significant differences emerged between groups with and without complications. Procedures increased over time, but complications and unsuccessful procedures remained stable. CONCLUSION: ERCP complications align with international data, often not requiring invasive treatment. Enhanced exposure to such cases correlates with fewer complications and failures. Prospective studies are essential to identify complication and failure predictors.

Protein-losing enteropathy secondary to graft-versus-host disease.

Protein-losing enteropathy is a gastrointestinal complication of Graft versus host disease. The clinical presentation can be similar to that of multiple pathologies and represents a diagnostic challenge for clinicians. We report a 23-year-old man with a history of acute lymphoid leukemia that required allogeneic hematopoietic stem cell transplantation that came to evaluation due to anasarca.

Phlegmonous gastritis associated with invasive Pseudomonas aeruginosa infection.

We report the case of a 49 years-old female that was hospitalized due to a recent diagnosis of acute lymphoblastic leukemia. As a consequence of induction chemotherapy (CALGB 10403 scheme), she developed severe neutropenia (0.04 10^3/ul). On day 6 of chemotherapy, she complained of epigastric pain, fever, coffee ground emesis, and melena.

A comprehensive systematic review and meta-analysis of risk factors for rebleeding following device-assisted enteroscopy therapy of small-bowel vascular lesions.

INTRODUCTION: the aim of this study was to determine the risk factors for rebleeding following device-assisted enteroscopy therapy of small bowel vascular lesions. METHODS: this is a systematic review and meta-analysis. A literature search was performed from January 2003 to October 2019. All studies reporting on at least one risk factor for bleeding recurrence after endoscopic therapy of small bowel vascular lesions were included. A meta-analysis of those risk factors reported in at least three studies was performed to assess their association with rebleeding. The OR and 95 % CI were used for binary outcome data. Heterogeneity analysis was performed using the Tau and I2 index. If I2 > 20 %, potential sources of heterogeneity were identified by sensitivity analyses and a random-effect model was used. RESULTS: the search identified a total of 572 articles and 35 full-text records were assessed for eligibility after screening. Finally, eight studies that included 548 patients were selected. The overall median rebleeding rate was 38.5 % (range: 10.9-53.3 %) with a median follow-up of 24.5 months. Female sex (OR: 1.96, 95 % CI: 1.14-3.37, p = 0.01, I2 = 0 %), Osler-Weber syndrome (OR: 4.35, 95 % CI: 1.22-15.45, p = 0.02, I2 = 0 %) and cardiac disease (OR: 1.89, 95 % CI: 1.12-2.97, p = 0.005, I2: 0 %) were associated with rebleeding. According to the sensitivity analysis, overt bleeding (OR: 2.13, 95 % CI: 1.22-3.70, p = 0.007, I2 = 0 %), multiple lesions (OR: 4.57, 95 % CI: 2.04-10.22, p < 0.001, I2 = 0 %) and liver cirrhosis (OR: 2.61, 95 % CI: 1.11-6.13, p = 0.03, I2 = 0 %) were also predictors for rebleeding. CONCLUSIONS: patient characteristics and comorbidities should be considered for follow-up patient management after effective device-assisted endoscopic therapy, as they can predict rebleeding.

Endoscopic retrograde cholangiopancreatography by double-balloon enteroscopy in patients with surgically altered gastrointestinal anatomy.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) allows a diagnostic and therapeutic evaluation of pancreatobiliary diseases. However, the procedure in patients with surgically altered gastrointestinal anatomy represents a technical challenge. OBJECTIVE: to report the diagnostic and therapeutic outcome of device-assisted enteroscopy (DAE) ERCP in patients with a surgically altered gastrointestinal anatomy. METHODS: a prospective cohort of patients with a history of surgically altered gastrointestinal anatomy undergoing DAE-ERCP in a referral center was used. A double-balloon enteroscope was used to reach the papillary area or the bilio-enteric anastomosis. The clinical and endoscopic characteristics, and technical, diagnostic and therapeutic success were described. Clinical and endoscopic differences were evaluated according to diagnostic success, as well as the biochemical response in those patients with therapeutic success. RESULTS: ninety-six procedures were included in the study in 75 patients. Roux-en-Y hepaticojejunostomy (RYHJ) was the main surgical anatomy (82.3%) and cholangitis was the main indication for ERCP (49%). Diagnostic success was obtained in 69.8% of the participants. Of these, therapeutic success was obtained in 83.6% (overall success 58.3%). Cases with a diagnostic success had a higher frequency of cholangiography compared to those without diagnostic success (94% vs 0%, p < 0.001), as well as a lower probability of a failed cannulation (1.5% vs 100%, p < 0.001). A significant improvement was observed in patients with a therapeutic success in bilirubin, transaminases and alkaline phosphatase levels (p < 0.05). CONCLUSIONS: ERCP by means of double-balloon enteroscopy is a useful technique in patients with a surgically altered gastrointestinal anatomy, in whom access to the bile duct is required. However, these procedures are very challenging and diagnostic and therapeutic success where achieved in up to 60% of cases.

Higher adenoma detection rate with the endocuff: a randomized trial.

Background and study aim Different techniques have been introduced to improve the endoscopist's view and enhance the detection of polyps. The endocuff is a polymer sleeve cap that is connected to the tip of the colonoscope in order to improve visualization of the mucosa during colonoscopy. The aim of the study was to compare adenoma detection rates (ADR) of endocuff-assisted colonoscopy and conventional colonoscopy. Patients and methods Patients 50 years or older were randomized into two groups: an endocuff-assisted colonoscopy group and a conventional colonoscopy group without the endocuff. Results A total of 337 patients were included: 174 in the endocuff group and 163 in the conventional group. The median age was 61 years (interquartile range 55 - 70 years), and 74 % were women. The ADR was higher in the endocuff group than in the conventional group (22.4 % vs. 13.5 %; P = 0.02). The mean number of adenomas was 0.30 (SD 0.25) in the endocuff group and 0.21 (SD 0.26) in the conventional group (P â€Š= 0.02). The rate of ileal intubation was lower in the endocuff group (73 % vs. 87 %; P < 0.001). No serious adverse events occurred with the use of the endocuff. Conclusions Endocuff colonoscopy achieved a greater ADR than conventional colonoscopy.Trial registered at ClinicalTrials.gov (NTC02387593).

[Diagnosis agreement between capsule endoscopy and double-balloon enteroscopy in obscure gastrointestinal bleeding at a referral center]. / Concordancia diagnóstica entre la cápsula endoscópica y enteroscopia de doblebalón en la hemorragia digestiva media en un centro de referencia.

BACKGROUND AND AIM: Capsule endoscopy and double balloon enteroscopy are well-recognized procedures in obscure gastrointestinal bleeding, with many factors that may influence their diagnosis yield. The aim of the present study was to characterize the degree of agreement between both techniques with focus on the type of lesion in a large cohort of patients at a referral center. MATERIAL AND METHOD: One thousand two hundred and nine capsules were administered in 1,078 patients and 381 enteroscopies were performed in 361 patients with obscure-gastrointestinal bleeding from 2004 to 2014. RESULTS: Both procedures were carried out in 332 patients (mean age: 65.22 +/- 15.41, 183 men) and they have a similar diagnosis yield (70.5% vs. 69.6%, p = 0.9). Overall enteroscopy diagnosis yield was higher within patients with a previous positive capsule endoscopy (79.3% vs. 27.9%, p < 0.001). The degree of agreement was very good for polyps (0.89 [95% CI: 0.78-0.99]), good for vascular lesions (0.66 [95% CI: 0.55-0.77]) and tumors(0.66 [95% CI: 0.55-0.76]) and moderate for ulcers (0.56 [95% CI: 0.46-0.67]). Diverticula (0.39 [95% CI: 0.29-0.5]) achieved a fair agreement. The results of CE and DBE differed in 73 patients (22%). CONCLUSIONS: The present study confirms that although overall diagnostic yield by capsule endoscopy and double-balloon enteroscopy is similar, there are many factors which can modify these values, mainly the type of lesion.

Minimal hepatic encephalopathy.

The term minimal hepatic encephalopathy (MHE) refers to the subtle changes in cognitive function, electrophysiological parameters, cerebral neurochemical/neurotransmitter homeostasis, cerebral blood flow, metabolism, and fluid homeostasis that can be observed in patients with cirrhosis who have no clinical evidence of hepatic encephalopathy; the prevalence is as high as 84% in patients with hepatic cirrhosis. Physician does generally not perceive cirrhosis complications, and neuropsychological tests and another especial measurement like evoked potentials and image studies like positron emission tomography can only make diagnosis. Diagnosis of minimal hepatic encephalopathy may have prognostic and therapeutic implications in cirrhotic patients. The present review pretends to explore the clinic, therapeutic, diagnosis and prognostic aspects of this complication.

Can topical epinephrine application to the papilla prevent pancreatitis after endoscopic retrograde cholangiopancreatography? Results from a double blind, multicentre, placebo controlled, randomised clinical trial.

BACKGROUND AND STUDY AIMS: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is a complication associated with important morbidity, occasional mortality and high costs. Preventive strategies are suboptimal as PEP continues to affect 4% to 9% of patients. Spraying epinephrine on the papilla may decrease oedema and prevent PEP. This study aimed to compare rectal indomethacin plus epinephrine (EI) versus rectal indomethacin plus sterile water (WI) for the prevention of PEP. PATIENTS AND METHODS: This multicentre randomised controlled trial included patients aged >18 years with an indication for ERCP and naive major papilla. All patients received 100 mg of rectal indomethacin and 10 mL of sterile water or a 1:10 000 epinephrine dilution. Patients were asked about PEP symptoms via telephone 24 hours and 7 days after the procedure. The trial was stopped half way through after a new publication reported an increased incidence of PEP among patients receiving epinephrine. RESULTS: Of the 3602 patients deemed eligible, 3054 were excluded after screening. The remaining 548 patients were randomised to EI group (n=275) or WI group (n=273). The EI and WI groups had similar baseline characteristics. Patients in the EI group had a similar incidence of PEP to those in the WI group (3.6% (10/275) vs 5.12% (14/273), p=0.41). Pancreatic duct guidewire insertion was identified as a risk factor for PEP (OR 4.38, 95% CI (1.44 to 13.29), p=0.009). CONCLUSION: Spraying epinephrine on the papilla was no more effective than rectal indomethacin alone for the prevention of PEP. TRIAL REGISTRATION NUMBER: This study was registered with ClinicalTrials.gov (NCT02959112).

Prevalence of burnout syndrome in gastroenterologists and endoscopists: results of a national survey in Mexico.

BACKGROUND: Burnout syndrome (BOS) is characterized by emotional exhaustion, depersonalization and reduced personal accomplishment. It affects doctors, patients and their inter-relationship. There is a lack of data on BOS in Mexico. The main objective of the present study is to evaluate the prevalence of BOS in physician members of the Mexican gastroenterological association (MGA) and Mexican association for gastrointestinal endoscopy (MAGE). MATERIALS AND METHODS: Cross sectional, prospective study through anonymous electronic survey via e-mail, sent to members of the MGA (n = 1192) and MAGE (n = 600). The survey included questions about basic sociodemographic information, Maslach Burnout Inventory, and factors potentially associated with BOS. Continuous variables were summarized as means and ANOVA or Kruskal-Wallis test were used to compare groups. Nominal variables were summarized as proportions and Fisher's exact test or Χ2 test were used, as appropriate. RESULTS: A total of 1792 e-mail invitations were delivered and 411 answers were received with a response rate of 22.9%. The prevalence of BOS according to the Maslach Burnout Inventory was 26.3% (108/411). The prevalence of BOS according to the single-item self-defined burnout question (SISDBOQ) was 32.6% (134/411). The Kappa coefficient for emotional exhaustion between the SISDBOQ and Maslach inventory was 0.48 (p = 0.0001). Factors associated with BOS included performing endoscopic procedures (OR 2.9 (1.2-6.6); p = 0.008), lack of support from colleagues upon complications (OR 0.2 (0.1-0.4); p = 0.0001), receiving frequent reprimands from superiors (OR 2.4 (1.5-3.8); p = 0.0001), work unrelated to medicine (OR 2.4 (1.4-3.9); p = 0.0001), work violence/harassment (OR 3.0 (1.9-4.9); p = 0.0001) and living in a big city (OR 1.9 (1.2-3); p = 0.005). CONCLUSION: BOS is a frequent entity in Mexican gastroenterologists and endoscopists. There are potentially modifiable factors associated with BOS.

Acute-on-chronic liver failure: a review.

There is no universally accepted definition of acute-on-chronic liver failure; however, it is recognized as an entity characterized by decompensation from an underlying chronic liver disease associated with organ failure that conveys high short-term mortality, with alcoholism and infection being the most frequent precipitating events. The pathophysiology involves inflammatory processes associated with a trigger factor in susceptible individuals (related to altered immunity in the cirrhotic population). This review addresses the different definitions developed by leading research groups, epidemiological and pathophysiological aspects, and the latest treatments for this entity.
