RESUMO

While the endoscopic management of surgical complications like leaks, fistulas, and perforations is rapidly evolving, its core principles revolve around closure, drainage, and containment. Effectively managing these conditions relies on several factors, such as the underlying cause, chronicity of the lesion, tissue viability, co-morbidities, availability of devices, and expertise required to perform the endoscopy. In contrast to acute perforation, fistulas and leaks often demand a multimodal approach requiring more than one session to achieve the required results. Although the ultimate goal is complete resolution, these endoscopic interventions can provide clinical stability, enabling enteral feeding to lead to early hospital discharge or elective surgery. In this discussion, we emphasize the current state of knowledge and the prospective role of endoscopic interventions in managing surgical complications.

RESUMO

BACKGROUND AND AIMS: Upper GI bleeding (UGIB) is a common medical emergency associated with high resource utilization, morbidity, and mortality. Timely EGD can be challenging from personnel, resource, and access perspectives. PillSense (EnteraSense Ltd, Galway, Ireland) is a novel swallowed bleeding sensor for the detection of UGIB, anticipated to aid in patient triage and guide clinical decision-making for individuals with suspected UGIB. METHODS: This prospective, open-label, single-arm comparative clinical trial of a novel bleeding sensor for patients with suspected UGIB was performed at a tertiary care center. The PillSense system consists of an optical sensor and an external receiver that processes and displays data from the capsule as "Blood Detected" or "No Blood Detected." Patients underwent EGD within 4 hours of capsule administration; participants were followed up for 21 days to confirm capsule passage. RESULTS: A total of 126 patients were accrued to the study (59.5% male; mean age, 62.4 ± 14.3 years). Sensitivity and specificity for detecting the presence of blood were 92.9% (P = .02) and 90.6% (P < .001), respectively. The capsule's positive and negative predictive values were 74.3% and 97.8%, and positive and negative likelihood ratios were 9.9 and .08. No adverse events or deaths occurred related to the PillSense system, and all capsules were excreted from patients on follow-up. CONCLUSIONS: The PillSense system is safe and effective for detecting the presence of blood in patients evaluated for UGIB before upper GI endoscopy. It is a rapidly deployed tool, with easy-to-interpret results that will affect the diagnosis and triage of patients with suspected UGIB. (Clinical trial registration number: NCT05385224.).

RESUMO

BACKGROUND AND AIMS: Variation in colorectal neoplasia detection limits the effectiveness of screening colonoscopy. By evaluating neoplasia detection rates of individual colonoscopists, we aimed to quantify the effects of pre-procedural knowledge of a positive (+) multi-target stool DNA (mt-sDNA) on colonoscopy quality metrics. METHODS: We retrospectively identified physicians who performed a high volume of + mt-sDNA colonoscopies; colorectal neoplasia at post-mt-sDNA colonoscopy was recorded. These colonoscopists were stratified into quartiles based on baseline adenoma detection rates. Baseline colonoscopy adenoma detection rates and sessile serrated lesion detection rates were compared to post-mt-sDNA colonoscopy neoplasia diagnosis rates among each quartile. Withdrawal times were measured from negative exams. RESULTS: During the study period (2014-17) the highest quartile of physicians by volume of post-mt-sDNA colonoscopies were evaluated. Among thirty-five gastroenterologists, their median screening colonoscopy adenoma detection rate was 32% (IQR, 28-39%) and serrated lesion detection rate was 13% (8-15%). After + mt-sDNA, adenoma diagnosis increased to 47% (36-56%) and serrated lesion diagnosis increased to 31% (17-42%) (both p < 0.0001). Median withdrawal time increased from 10 (7-13) to 12 (10-17) minutes (p < 0.0001) and was proportionate across quartiles. After + mt-sDNA, lower baseline detectors had disproportionately higher rates of adenoma diagnosis in female versus male patients (p = 0.048) and higher serrated neoplasia diagnosis rates among all patients (p = 0.0092). CONCLUSIONS: Knowledge of + mt-sDNA enriches neoplasia diagnosis compared to average risk screening exams. Adenomatous and serrated lesion diagnosis was magnified among those with lower adenoma detection rates. Awareness of the mt-sDNA result may increase physician attention during colonoscopy. Pre-procedure knowledge of a positive mt-sDNA test improves neoplasia diagnosis rates among colonoscopists with lower baseline adenoma detection rates, independent of withdrawal time.

RESUMO

Background and study aims Gastric outlet obstruction (GOO) is traditionally managed with surgical gastroenterostomy (surgical-GE) and enteral stenting (ES). Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is now a third option. Large studies assessing their relative risks and benefits with adequate follow-up are lacking. We conducted a comparative analysis of patients who underwent EUS-GE, ES, or surgical-GE for GOO. Patients and methods In this retrospective comparative cohort study, consecutive patients presenting with GOO who underwent EUS-GE, ES, or surgical-GE at two academic institutions were reviewed and independently cross-edited to ensure accurate reporting. The primary outcome was need for reintervention. Secondary outcomes were technical and clinical success, length of hospital stay (LOS), and adverse events (AEs). Results A total of 436 patients (232 EUS-GE, 131 ES, 73 surgical-GE) were included. The median duration of follow-up of the entire cohort was 185.5 days (interquartile range 55.25-454.25 days). The rate of reintervention in the EUS-GE group was lower than in the ES and surgical-GE groups (0.9 %, 12.2 %, and 13.7 %, P  < 0.0001). Technical success was achieved in 98.3 %, 99.2 %, and 100 % ( P  = 0.58), and clinical success was achieved in 98.3 %, 91.6 %, and 90.4 % ( P  < 0.0001) in the EUS-GE, ES, and surgical-GE groups, respectively. The EUS-GE group had a shorter LOS (2 days vs. 3 days vs. 5 days, P  < 0.0001) and a lower AE rate than the ES and surgical-GE groups (8.6 % vs. 38.9 % vs. 27.4 %, P  < 0.0001). Conclusion This large cohort study demonstrates the safety and palliation durability of EUS-GE as an alternative strategy for GOO palliation in select patients.

RESUMO

IMPORTANCE: Patients with familial adenomatous polyposis (FAP) are at markedly increased risk for duodenal adenomas and cancer. Combination sulindac and erlotinib was previously shown to reduce duodenal polyp burden but was associated with a relatively high adverse event (AE) rate. OBJECTIVE: To evaluate if a once weekly dosing schedule for erlotinib intervention improves the AE profile, while still providing efficacy with respect to reduced polyp burden, in participants with FAP. DESIGN, SETTING AND PARTICIPANTS: Single-arm trial, enrolling 46 participants with FAP, conducted from October 2017 to September 2019 in eight academic cancer centres. EXPOSURES: Participants self-administered 350 mg of erlotinib by mouth, one time per week for 6 months. MAIN OUTCOMES AND MEASURES: Duodenal polyp burden (sum of polyp diameters) was assessed in the proximal duodenum by esophagogastroduodenoscopy performed at baseline and 6 months, with mean per cent change defined as the primary efficacy outcome of interest. Rate of grade 2-3 AEs was evaluated as a co-primary outcome. Secondary outcomes included changes in total duodenal polyp count, along with changes in lower gastrointestinal (GI) polyp burden and count (for participants examined by optional lower endoscopy). RESULTS: Forty-six participants (mean age, 44.1 years (range, 18-68); women, 22 (48%)) were enrolled; 42 participants completed 6 months of intervention and were included in the per-protocol analysis. Duodenal polyp burden was significantly reduced after 6 months of weekly erlotinib intervention, with a mean per cent change of -29.6% (95% CI, -39.6% to -19.7%; p<0.0001). Similar results were observed in subgroup analyses defined by participants with advanced duodenal polyposis (Spigelman 3) at baseline (mean, -27%; 95% CI, -38.7% to -15.2%; p<0.0001). Post-intervention Spigelman stage was downstaged in 12% of the participants. Lower GI polyp number was also decreased after 6 months of intervention (median, -30.8%; IQR, -47.4% to 0.0%; p=0.0256). Grade 2 or 3 AEs were reported in 71.7% of subjects, with only two experiencing grade 3 toxicity at least possibly related to intervention. CONCLUSION: In this single-arm, multi-centre trial of participants with FAP, erlotinib one time per week resulted in markedly lower duodenal polyp burden, and modestly reduced lower GI polyp burden, after 6 months of intervention. While AEs were still reported by nearly three-quarters of all participants, these events were generally lower grade and well-tolerated. These findings support further investigation of erlotinib as an effective, acceptable cancer preventive agent for FAP-associated GI polyposis. TRIAL REGISTRATION NUMBER: NCT02961374.

RESUMO

BACKGROUND: Residual food (RF) during esophagogastroduodenoscopy (EGD) is thought, but not proven, to be a risk factor for gastric-to-pulmonary aspiration. AIMS: The aims of this study were to determine the prevalence of RF during EGD, to investigate whether RF was associated with an increased risk of aspiration, especially when monitored anesthesia care (MAC) or general anesthesia (GA) were administered, and to determine whether aspiration associated with RF led to a more severe clinical outcome. METHODS: Patients undergoing EGD between October 2012 and September 2018 were identified. Patient age, sex, aspiration events, RF, sedation type, structural foregut abnormalities, and diagnoses associated with impaired esophageal or gastric motility were noted. The clinical course after an aspiration event was evaluated. RESULTS: RF was identified during 4% of 81,367 EGDs. Aspiration events occurred during 41 (5/10,000) procedures. Aspiration was more likely to occur in patients with RF (odds ratio [OR] 15.1) or those receiving MAC or GA (OR 9.6 and 16.8 relative to conscious sedation, respectively). RF and MAC/GA were synergistically associated with increased odds of aspiration. In a multivariate nominal logistic regression model, older age (OR 2.6), MAC (OR 3.8), GA (OR 4.4), vagotomy (OR 5.2), achalasia (OR 3.8), and RF (OR 10.0) were risk factors for aspiration. Aspiration events in the presence or absence of RF led to similar clinical outcomes. CONCLUSIONS: While aspiration events are rare in patients undergoing EGD, RF and the use of MAC or GA were associated with substantially increased odds of aspiration.

RESUMO

BACKGROUND: Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures. METHODS: Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed. Primary outcomes included technical success, early clinical success, and adverse events (AEs). Other outcomes included rates of stent migration and re-intervention after LAMS removal. RESULTS: One hundred and nine patients who underwent 128 LAMS placements (67.9% female, mean age of 54.3 ± 14.2 years) were included, and 70.6% of the patients had failed prior endoscopic treatments. The majority of strictures (83.5%) were anastomotic, and the most common stricture site was the gastrojejunal anastomosis (65.9%). Technical success was achieved in 100% of procedures, while early clinical success was achieved in 98.4%. The overall stent-related AE rate was 25%. The migration rate was 27.3% (35/128). Of these, five stents were successfully repositioned endoscopically. The median stent dwell time was 119 days [interquartile range (IQR) 68-189 days], and the median follow-up duration was 668.5 days [IQR: 285.5-1441.5 days]. The re-intervention rate after LAMS removal was 58.3%. CONCLUSIONS: LAMS is an effective therapeutic option for benign GI strictures, offering high technical and early clinical success. However, the re-intervention rate after LAMS removal was high. In select cases, using LAMS placement as destination therapy with close surveillance is a reasonable option.

RESUMO

OBJECTIVE: To describe the clinical, endoscopic, and histologic features in patients with acute esophageal necrosis (AEN). PATIENTS AND METHODS: In this retrospective cohort study, patients who were diagnosed as having AEN at Mayo Clinic sites in Minnesota, Florida, and Arizona between January 1, 1996, and January 31, 2021, were included. Data were collected on patient clinical characteristics and endoscopic and pathologic findings. RESULTS: The study included 79 patients with AEN with a median (range) age of 64 years (12 to 91 years); 53 (67.1%) were men. Predominant presenting symptoms were hematemesis (49 of 79 [62.0%]), abdominal pain (29 [36.7%]), and melena (20 [25.3%]). Shock was the triggering event for AEN in 49 (62.0%). The 30- and 90-day mortality were 24.0% (19 of 79) and 31.6% (25), respectively. The presence of coexisting infection or bacteremia was significantly associated with 90-day mortality (P<.01). Endoscopically, involvement of the distal third only, distal two-thirds only, and entire esophagus was observed in 31.6% (24 of 76), 39.5% (30), and 29.0% (22), respectively. The length of esophageal involvement correlated with duration of hospitalization (P=.05). The endoscopic appearance of the esophageal mucosa ranged from predominantly white (21 of 44 [47.7%]) to mixed white and black (13 [29.6%]) to predominantly black (10 [22.7%]), and sloughing was present in 18 (40.9%). In the 26 patients with histopathologic findings available for review, 25 (96.1%) had necrosis and/or ulceration with abundant pigmentation. Among the 79 patients, 39 (49.4%) had a follow-up esophagogastroduodenoscopy; 26 of these 39 patients (66.7%) had resolution while 5 had persistent AEN, 4 of whom had improvement. Esophageal strictures developed in 7 of the 39 patients (18.0%). CONCLUSION: Acute esophageal necrosis is a serious condition observed in critically ill patients. Its endoscopic appearance can be highly variable. In patients with an unclear diagnosis, esophageal biopsies may be helpful given the characteristic histologic findings.

RESUMO

INTRODUCTION: Esophageal adenocarcinoma (EAC) is an aggressive cancer, associated with reflux esophagitis and intestinal metaplasia (IM). One underlying biological mechanism, which possibly drives the development of EAC, is the dysregulated expression of Bone Morphogenetic Proteins (BMPs). AIM: To investigate if local delivery of Noggin, a BMP antagonist, reduced EAC. METHODS: After obtaining proof of principal on local delivery of a Noggin/Sucralfate substance, a randomized controlled trial to test the effects of Noggin on EAC development was performed in a surgical rat model. In the model, an esophago-jejunostomy leads to development of reflux-esophagitis, IM and eventually EAC. Rats were treated by Noggin/Sucralfate or Sucralfate alone. Treatment was administered from 26 to 29 weeks after the operation. RESULTS: Of the 112 operated rats, 52 survived beyond 26 weeks. Finally, 25 rats treated with Noggin/Sucralfate and 21 with Sucralfate, were evaluated. At the end, 39 (85%) of the animals had IM while 28 (61%) developed cancer. There were significantly more cancers in the Noggin/Sucralfate arm (50%) versus the Sucralfate group (73%) (Chi square, P < 0.05). Most cancers were mucous producing T3 adenocarcinomas. There were no significant differences in the amount of IM, size or grade of the cancers, or expression of columnar and squamous markers between the two groups. CONCLUSION: In this study, we demonstrated that inhibition of BMPs by Noggin reduced development of EAC in a surgical esophagitis-IM-EAC rat model. In future, effective targeting of the BMP pathway with selective BMP-inhibitors could become an important asset to improve EAC patient outcome.

RESUMO

BACKGROUND: Endoscopic cyanoacrylate (glue) injection of fundal varices may result in life-threatening embolic adverse events through spontaneous gastrorenal shunts (GRSs). Balloon-occluded retrograde transvenous occlusion (BRTOcc) of GRSs during cyanoacrylate injection may prevent serious systemic glue embolization through the shunt. This study aimed to evaluate the efficacy and safety of a combined endoscopic-interventional radiologic (BRTOcc) approach for the treatment of bleeding fundal varices. METHODS: We retrospectively analysed the data of patients who underwent the combined procedure for acutely bleeding fundal varices between January 2010 and April 2018. Data were extracted for patient demographics, clinical and endoscopic findings, technical details, and adverse events of the endoscopic-BRTOcc approach and patient outcomes. RESULTS: We identified 30 patients (13 [43.3%] women; median age 58 [range, 25-92] years) with gastroesophageal varices type 2 (53.3%, 16/30) and isolated gastric varices type 1 (46.7%, 14/30) per Sarin classification, and median clinical and endoscopic follow-up of 151 (range, 4-2,513) days and 98 (range, 3-2,373) days, respectively. The median volume of octyl-cyanoacrylate: Lipiodol injected was 7 (range, 4-22) mL. Procedure-related adverse events occurred in three (10.0%) patients, including transient fever, non-life-threatening pulmonary glue embolism, and an injection-site ulcer bleed. Complete gastric variceal obturation was achieved in 18 of 21 patients (85.7%) at endoscopic follow-up. Delayed variceal rebleeding was confirmed in one patient (3.3%) and suspected in two patients (6.7%). Although no procedure-related deaths occurred, the overall mortality rate was 46.7%, primarily from liver-disease progression and co-morbidities. CONCLUSION: The combined endoscopic-BRTOcc procedure is a relatively safe and effective technique for bleeding fundal varices, with a high rate of variceal obturation and a low rate of serious adverse events.

RESUMO

Background and aims Endoscopic resections are associated with bleeding and perforation and may be managed with through-the-scope (TTS) clips, over-the-scope clips and endoscopic suturing. The aim of this preclinical study was to compare technical success of closure using a novel TTS tissue helix tack and suture device (X-Tack) to TTS clips in a porcine model. Materials and methods Four subjects underwent 40 mucosal resections, diameter range 25-50 mm, in the stomach (n = 24) and colon (n = 16). Closures were randomized to X-Tack (n = 24) or clip (n = 16). Animals underwent weekly endoscopic follow-up for 4 weeks. Results Technical closure with X-Tack was successful in 24 of 24 (100 %) cases and with clips in 13 of 16 cases (81.3 %) ( P  = 0.0001). One colonic perforation occurred and was successfully managed using X-Tack. The rate of healing was not statistically different between the groups, and all sites healed at 4 weeks including the perforation and were confirmed by histology. Conclusions Compared to TTS clip, X-Tack is superior for effecting large mucosal defect closure, including durable sealing of full-thickness perforation. There was no difference in rate of healing between devices.

RESUMO

Polyphenon E (Poly E) is a green tea polyphenol preparation whose most active component is epigallocatechin gallate (EGCG). We studied the cancer preventive efficacy and safety of Poly E in subjects with rectal aberrant crypt foci (ACF), which represent putative precursors of colorectal cancers. Eligible subjects had prior colorectal advanced adenomas or cancers, and had ≥5 rectal ACF at a preregistration chromoendoscopy. Subjects (N = 39) were randomized to 6 months of oral Poly E (780 mg EGCG) daily or placebo. Baseline characteristics were similar by treatment arm (all P >0.41); 32 of 39 (82%) subjects completed 6 months of treatment. The primary endpoint was percent reduction in rectal ACF at chromoendoscopy comparing before and after treatment. Among 32 subjects (15 Poly E, 17 placebo), percent change in rectal ACF number (baseline vs. 6 months) did not differ significantly between study arms (3.7% difference of means; P = 0.28); total ACF burden was also similar (-2.3% difference of means; P = 0.83). Adenoma recurrence rates at 6 months were similar by arm (P > 0.35). Total drug received did not differ significantly by study arm; 31 (79%) subjects received ≥70% of prescribed Poly E. Poly E was well tolerated and adverse events (AE) did not differ significantly by arm. One subject on placebo had two grade 3 AEs; one subject had grade 2 hepatic transaminase elevations attributed to treatment. In conclusion, Poly E for 6 months did not significantly reduce rectal ACF number relative to placebo. Poly E was well tolerated and without significant toxicity at the dose studied. PREVENTION RELEVANCE: We report a chemoprevention trial of polyphenon E in subjects at high risk of colorectal cancer. The results show that polyphenon E was well tolerated, but did not significantly reduce the number of rectal aberrant crypt foci, a surrogate endpoint biomarker of colorectal cancer.

RESUMO

BACKGROUND: In selected cases of post-bariatric leaks and fistulas, endoscopy is an initial treatment modality. Management can be complex and require multiple endoscopic sessions with varying degrees of success. Our aim was to describe our tertiary care experience on endoscopy management of refractory post-bariatric leaks and fistulas. METHODS: Patients with post-bariatric leaks and/or fistulas who failed an initial endoscopic intervention were included. Endoscopic treatments were classified into four strategies: (1) closure management, (2) active drainage, (3) passive drainage, and (4) plugging. Clinical success and adverse events were assessed. RESULTS: A total of 25 patients (mean age = 45.3 ± 11.8 years and 56% female) were included. Clinical success was achieved in 20 patients (80%) with a mean of 3.0 ± 1.5 procedures and a median time to healing of 114.5 (53-210.3) days. Closure and plugging were the main successful strategies used for early and acute leaks/fistulas, while drainage was for late and chronic leaks/fistulas. Adverse events were observed in 13 patients (52%) with one serious adverse event. Patients with fistulas had a lower success rate (72.2% vs. 100%, P = 0.052). Of those with clinical failure (n = 5), four underwent reconstructive surgery, eventually led to success in 3 patients. The other one died of septic shock related to a complicated fistula. CONCLUSIONS: Complex multi-modality endoscopic management ultimately achieved clinical success in most cases of refractory leaks/fistulas post-bariatric with an acceptable safety profile. However, a close follow-up to detect the development of long-term failure is warranted. These patients should be referred to a specialized bariatric center with expertise in bariatric endoscopy and surgery.

RESUMO

BACKGROUND & AIMS: Self-expanding metal stents (SEMS) are routinely used to palliate malignant dysphagia. However esophageal SEMS can migrate or obstruct due to epithelial hyperplasia. The aim of this study was to evaluate the rates and factors predicting migration and obstruction, and the nutritional outcomes in partially covered (pc) vs. fully covered (fc) SEMS vs. fcSEMS with antimigration fins (AF) placed for malignant dysphagia. METHODS: A retrospective review of consecutive patients undergoing SEMS placement for malignant dysphagia at three academic medical centers. RESULTS: Among 357 patients, there were 55 (15.4%) stent migrations, 45 (12.6%) obstructions from epithelial hyperplasia, and 20 (5.6%) food impactions. Median overall survival was 79 days (IQR 41,199). The percent weight change/change in albumin at 30 and 60 days after SEMS placement were -2.24%/-0.544 g/dL and -2.98%/-0.55 g/dL, respectively. Stent migration occurred significantly more often with fcSEMS than pcSEMS (25.3% vs 10.9%; P < .003), but there was no difference when either group was compared to fcSEMS-AF (19.3%). The overall rate of epithelial hyperplasia resulting in stent obstruction was low (12.6%) and not different between stent types. Factors associated with increased risk of SEMS migration on multivariable logistic regression included stricture traversability with a diagnostic endoscope (OR, 2.37; 95% CI, 1.29-4.35) and use of fcSEMS (OR, 2.56; 1.31-5.00) or fcSEMS-AF (OR, 2.30, 1.03-5.14). CONCLUSIONS: Traversability of a malignant esophageal stenosis predicts SEMS migration. In these patients with a limited overall survival, pcSEMS are associated with lower rates of stent migration and similar rates of obstruction compared to fcSEMS.

RESUMO

BACKGROUND: Bariatric surgery is by far the most effective treatment option available for successfully achieving and maintaining weight loss in the obese population, but it can also be associated with complications that lead to malnutrition. There is limited data on how enteral nutrition (EN) can be used to provide nutrition support in such cases. METHODS: Retrospective review of our Home Enteral Nutrition (HEN) database was conducted from February 2013 to April 2018 to identify patients who received HEN because of bariatric surgery-related complication. RESULTS: During the study period, 72 patients (86% female, mean age 50.3 ± 11.6 years) initiated HEN because of bariatric surgical complication. Most common bariatric surgery was Roux-en-Y (74%) and most common indication for HEN was malnutrition/failure to thrive (33%). HEN was most commonly provided through nasojejunal feeds and resulted in an average increase in body weight and body mass index from 74.8 kg and 26.5, respectively, before HEN to 76.9 kg and 27.2, respectively, at the end of the HEN period. Through HEN, patients received 22.2 ± 7.9 kcal/kg/d and 1.0 ± 0.3 g/kg/d protein, meeting 94% ± 17% of their energy goals and 95% ± 29% of their protein goals. Vitamin deficiencies were noted in 69% of patients at the time of HEN initiation, which improved to 10% after enteral feeds and appropriate vitamin supplementation. CONCLUSION: HEN is safe and effective in treating malnutrition and vitamin deficiencies that might occur as a complication of bariatric surgery, leading to avoidance of parenteral nutrition support in most cases.
