RESUMO

BACKGROUND AND AIMS: Training in interventional endoscopy is offered by nonaccredited advanced endoscopy fellowship programs (AEFPs). The number of these programs has increased dramatically with a concurrent increase in the breadth and complexity of interventional endoscopy procedures. Accreditation is governed by competency-based education, yet what constitutes a "high-quality" nonaccredited AEFP has not been defined. Using an evidence-based consensus process, we aimed to establish standards for AEFPs. METHODS: The RAND UCLA appropriateness method, a well-described modified Delphi process to develop quality indicators, was used. A task force established by the American Society for Gastrointestinal Endoscopy drafted potential quality indicators (structure, process, and outcome) in 6 categories: activity preceding training; structure of AEFPs; training in ERCP, EUS, and EMR; and luminal stent placement. Three rounds of iterative feedback from 20 experts were conducted. Round 0 involved discussion of project details. In round 1, experts independently ranked proposed quality indicators on a 9-point interval scale ranging from highly inappropriate (1) to highly appropriate (9). Next, proposed quality indicators were discussed and reworded in a group meeting followed by round 2, in which experts independently reranked proposed quality indicators and provided benchmarks (when applicable). The median score for each quality indicator was calculated. Mean absolute deviation from the median was calculated, and appropriateness of potential quality indicators was assessed using the BIOMED concerted action on appropriateness definition, P value method, and interpercentile range adjusted for symmetry definition. A quality indicator was deemed appropriate if the median score was ≥7 and met criteria for appropriateness using all 3 defined statistical methods. RESULTS: Of 89 proposed quality indicators, 37 statements met criteria as appropriate for a quality indicator (activity preceding training, 2; structure of AEFPs, 10; training in ERCP, 7; training in EUS, 8; training in EMR, 7; luminal stent placement, 3). Minimum thresholds were defined for 19 relevant quality indicators for number of trainers, procedures during fellowship, and procedures before assessment of competence. Among the final appropriate quality indicators were that all trainees should undergo qualitative and quantitative competence assessments using validated tools at least quarterly with documented feedback throughout the training period and that trainees should track outcomes and relevant quality metrics for specific procedures. CONCLUSIONS: This consensus process using validated methodology established standards for an AEFP in an effort to ensure adequate training in the most commonly taught interventional endoscopic procedures (ERCP, EUS, EMR, and luminal stent placement) during fellowship. An important component of an AEFP is the use of competency-based assessments that are compliant with the Accreditation Council for Graduate Medical Education's Next Accreditation System, with the goal of ensuring that trainees achieve specific milestones in their progression to achieving cognitive and technical competency.

RESUMO

OBJECTIVES: Accurate localization of a colonic lesion is crucial to successful resection. Although colonic tattooing is a widely accepted technique to mark lesions for future identification surgery or repeat colonoscopy, no consensus guidelines exist. The objective of this study was to determine whether the current tattooing practice at a tertiary medical center differs from recommendations in the literature and self-reported provider practice. METHODS: The study consisted of an observational retrospective chart review of patients who received colonic tattoos, as well as a provider survey of reported tattooing practices at a tertiary academic medical center. A total of 747 patients older than 18 years of age who underwent colonoscopy with tattoo were included. Forty-four gastroenterologists performing endoscopy were surveyed on tattooing techniques. RESULTS: In the majority of cases, neither the number of tattoos, location of the tattoo nor the distance from the lesion was specified within the report. Following the index procedure, a tattoo was detected in 75% of surgical resections and 73% of endoscopies. At the time of surgery, however, the tattoo and/or the lesion was detected approximately 94% of the time. Twenty-five endoscopists (56.8%) completed the survey. Differences were seen the between the chart review and reported practice. Most providers report placing ≥2 marks (87.2%); however, chart review revealed that only 56.2 % were tattooed with ≥2 marks. CONCLUSIONS: Variation exists between the reported tattooing practice and actual practice. Despite this, most tattoos are identified at the time of surgery or repeat endoscopy. Further research is needed to determine whether a standardized approach to tattooing and reporting could improve localization at repeat endoscopy.

RESUMO

Early esophageal cancer is confined to the mucosa or submucosa of the esophagus. While most esophageal cancer is detected at an advanced stage (requiring surgical resection, chemotherapy, and radiation), early-stage mucosal lesions may be detected through Barrett's surveillance programs or incidentally on diagnostic upper endoscopies performed for other reasons. These early-stage cancers are often amenable to endoscopic therapies, including mucosal resection, ablation, and cryotherapy. Studies suggest equivalent survival rates and reduced morbidity but higher recurrence rates with endoscopic removal of early-stage cancers compared to surgical resection. There is emerging data regarding the efficacy and long-term outcomes of endoscopic therapy for early esophageal cancer that is promising, and further research is needed to better define the role of endoscopic therapy in the management of early esophageal cancer.

RESUMO

OBJECTIVE: The objective of this study was to compare the effectiveness, morbidity, and mortality associated with endoscopic ampullectomy (EA) and surgical ampullectomy (SA). BACKGROUND: The proposed management of benign ampullary lesions includes local resection (EA or SA) and en bloc resection (pancreaticoduodenectomy). Most agree that en bloc resection entails a significant morbidity and mortality. No study has previously compared EA and SA for the treatment of benign ampullary lesions. METHODS: Medical records of patients selected for ampullectomy at Duke University Medical Center from 1991 to 2010 were reviewed. RESULTS: After review, 109 patients were confirmed to have undergone ampullectomy for a suspected benign ampullary lesion. Sixty-eight patients underwent EA, whereas 41 patients underwent SA. Patients in each group were identical in terms of age, sex, race, and comorbid conditions, except that EA had a higher rate of severe obesity (body mass index >35). Endoscopic ampullectomy was found to have a significantly reduced length of stay, lower morbidity, and readmission rates, but it had similar rates of mortality, margin-positive excisions, and reinterventions. CONCLUSIONS: In patients selected for ampullectomy for benign ampullary lesions, EA was found to have equivalent efficacy when compared with SA. Moreover, EA had lower morbidity and identical mortality. These findings suggest that patients would likely benefit from an aggressive endoscopic approach before consideration for surgery.

RESUMO

Background and study aims: It is common practice to perform ampullectomy without endoscopic ultrasound (EUS) for ampullary lesions < 1 cm but no data exists to support it. No studies have explored whether EUS findings of invasion correlate with malignancy or high-grade dysplasia (HGD) on pathology. We explored the association between adenoma size, pathology results, and invasion on EUS.  Patients and methods: This was a single-center retrospective cohort study at a large tertiary care academic hospital. Chart review was performed for 161 patients with benign ampullary lesions on endoscopic biopsy (identified by pathology records). The primary outcomes were mean size (mm) of adenomas and pathology findings with and without intraductal and/or duodenal wall invasion on EUS.  Results: Invasion was identified by EUS in 41 (34.1 %) of 120 patients who underwent EUS. The mean size of the lesion in these patients was 20.9 mm (±â€Š11.6 mm) compared to 13.9 mm (±â€Š11.3 mm, P = 0.0001) in patients without invasion. A receiver operating characteristic (ROC) curve (AUC 0.73, 95 % CI 0.63 - 0.83) revealed 100 % sensitivity for absence of invasion on EUS in lesions less than 6.5 mm. Invasion on EUS had sensitivity of 63.0 % (95 % CI 47.0 % - 77.0 %) and specificity 88.0 % (95 % CI 78.0 % - 95.0 %) for presence of malignancy, HGD or invasion on pathology. Conclusions: EUS should be considered for ampullary lesions > 6.5 mm. This study provides evidence to support the practice of ampullectomy without EUS for smaller adenomas. EUS evidence of invasion is highly specific for pathologic malignancy, HGD, or invasion (which preclude endoscopic ampullectomy).

RESUMO

BACKGROUND: Patients with metastatic disease of the liver can have hyperbilirubinemia due to a number of reasons, including biliary obstruction. The purpose of this study was to analyze patient outcomes after percutaneous biliary drainage (PBD) catheter insertion in patients with extensive hepatic metastatic tumor burden. METHODS: Out of 746 PBD insertions, 44 patients (24 males, 20 females, mean age 57.4 years, range, 34-80 years) had metastatic malignancy with a hepatic tumor burden of greater than 20% parenchymal volume based on pre-procedure computed tomography (CT) or magnetic resonance imaging (MRI). Laboratory data before and after PBD insertion were compared. Survival and outcomes analysis performed. A subanalysis was performed on patients with CT-demonstrated catheter traversal of tumoral tissue. RESULTS: A PBD catheter was successfully inserted in all patients. The mean serum bilirubin level decreased significantly from 10.9±6.4 mg/dL immediately prior to PBD insertion to 7.1±5.6 mg/dL (P<0.001) within one month post PBD insertion. Four patients (11%) demonstrated normalization of bilirubin levels to less than 1.6 mg/dL. Of the 14 patients with a post-procedure CT or MRI, the PBD catheter traversed a tumor in 11 (79%). One of these patients required a transfusion after the procedure and one had recurrent catheter exchanges due to pericatheter leakage. The 30-day overall survival was 41% with a median survival of 19 days. The percentage decrease in serum bilirubin after PBD insertion and pre-procedure international normalized ratio (INR) were correlated with improved survival (OR =3.7, P=0.010 and OR =4.9, P=0.028 respectively). The PBD-associated major complication rate was 16%. CONCLUSIONS: In patients with hyperbilirubinemia and extensive hepatic metastatic disease burden, survival was dismal after PBD catheter insertion. Serum bilirubin level normalization occurred rarely.

RESUMO

Extramedullary plasmacytoma (EMP) is a rare entity that can exist independently or in conjunction with underlying plasma cell myeloma (PCM). When there is underlying multiple myeloma, the presence of EMP portends a poor prognosis. The most common locations for an EMP include the gastrointestinal tract, pleura, testis, skin, peritoneum, liver, endocrine glands and lymph nodes; involvement of the gallbladder is exceedingly rare with only five other cases reported and only one of which was associated with PCM. EMP of the gallbladder can manifest as acute cholecystitis, biliary obstruction, or may be asymptomatic. Treatment is traditionally surgical resection plus adjuvant chemotherapy or autologous stem cell transplant. We present a case of a 53-year-old man with PCM who was found to have a gallbladder mass on imaging and underwent endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) of the mass, which was diagnostic of a plasma cell neoplasm.

RESUMO

AIM: To evaluate the success rates of performing therapy utilizing a rotational assisted enteroscopy device in endoscopic retrograde cholangiopancreatography (ERCP) in surgically altered anatomy patients. METHODS: Between June 1, 2009 and November 8, 2012, we performed 42 ERCPs with the use of rotational enteroscopy for patients with altered anatomy (39 with gastric bypass Roux-en-Y, 2 with Billroth II gastrectomy, and 1 with hepaticojejunostomy associated with liver transplant). The indications for ERCP were: choledocholithiasis: 13 of 42 (30.9%), biliary obstruction suggested on imaging: 20 of 42 (47.6%), suspected sphincter of Oddi dysfunction: 4 of 42 (9.5%), abnormal liver enzymes: 1 of 42 (2.4%), ascending cholangitis: 2 of 42 (4.8%), and bile leak: 2 of 42 (4.8%). All procedures were completed with the Olympus SIF-Q180 enteroscope and the Endo-Ease Discovery SB overtube produced by Spirus Medical. RESULTS: Successful visualization of the major ampulla was accomplished in 32 of 42 procedures (76.2%). Cannulation of the bile duct was successful in 26 of 32 procedures reaching the major ampulla (81.3%). Successful therapeutic intervention was completed in 24 of 26 procedures in which the bile duct was cannulated (92.3%). The overall intention to treat success rate was 64.3%. In terms of cannulation success, the intention to treat success rate was 61.5%. Ten out of forty two patients (23.8%) required admission to the hospital after procedure for abdominal pain and nausea, and 3 of those 10 patients (7.1%) had a diagnosis of post-ERCP pancreatitis. The average hospital stay was 3 d. CONCLUSION: It is reasonable to consider an attempt at rotational assisted ERCP prior to a surgical intervention to alleviate biliary complications in patients with altered surgical anatomy.

RESUMO

BACKGROUND: Pancreatic fluid collections can form after episodes of pancreatitis, either acute or chronic. The majority will resolve spontaneously but when decompression is mandated, endoscopic drainage is the method of choice. However, it is not void of complications. METHODS: We retrospectively reviewed the charts of 65 patients who underwent endoscopic drainage of pancreatic fluid collections in our institution. The primary outcomes examined included the incidence and type of complications associated with the endoscopic approach. RESULTS: Endoscopic ultrasound was utilized in 86.2% and transgastric approach was used in 81.5% of the cases. The complication rate was 17%. Specifically, complications recorded were infection (6%), perforation and acute abdomen necessitating surgical intervention (4.6%), pneumoperitoneum that was managed nonoperatively (3%), upper gastrointestinal bleed in the knife puncture site that resolved spontaneously (1.5%), and stent migration (1.5%). One patient died remotely to the endoscopic drainage after paracentesis of ascites that resulted in hemorrhagic shock. CONCLUSIONS: This study is one of the largest studies reporting the associated morbidity and mortality after endoscopic cyst-gastrostomy. Major and minor complications occurred at a rate of 17% in our study. Endoscopic approach is a safe draining method and should remain the approach of choice for pancreatic fluid collection decompression.

RESUMO

Dissection of the visceral arteries happens infrequently, with the superior mesenteric artery being the most commonly affected. Isolated dissection of the celiac trunk is rare, and only a few cases have been reported in the medical literature. We report the case of a 51-year-old male who presented with abdominal pain and was subsequently diagnosed with a celiac trunk dissection with secondary pancreatitis and pancreatic infarction. The patient's symptoms improved with conservative medical management. We review the current literature involving celiac trunk dissection and its management, and provide discussion regarding this unrecognized complication of pancreatitis.

RESUMO

Groove pancreatitis is a rare form of chronic pancreatitis that affects the groove anatomical area between the head of the pancreas, duodenum, and common bile duct. We provide a summary of the clinical findings of 4 groove pancreatitis cases diagnosed at a tertiary academic medical center over a 5-year period. A detailed review of the current literature surrounding this clinical entity is also provided. Although rare, groove pancreatitis should be considered in the differential diagnosis of patients presenting with pancreatic head mass lesions, as appropriate diagnosis can help avoid unnecessary surgical procedures.

RESUMO

Retroperitoneal cystic lymphangiomas are rare tumors of the lymphatic system. These tumors usually present in childhood and are often diagnosed incidentally with imaging procedures. Although benign, they can grow to large sizes and become symptomatic due to their compressive effects. They can cause diagnostic dilemmas with other retroperitoneal cystic tumors including those arising from the liver, kidney, and pancreas. Endoscopic ultrasound (EUS) has become an invaluable tool in the assessment of cystic lesions in the region of the pancreas. This case describes a 66-year-old female who presented with 3 months of abdominal pain. Radiographic imaging was suggestive of a cystic lesion in the region of the pancreas. EUS was performed confirming a cystic lesion adjacent to the tail of the pancreas with subsequent fine needle aspiration fluid analysis consistent with a cystic lymphangioma.
