ABSTRACT

BACKGROUND: Despite the established efficacy of achalasia treatments on symptomatic outcomes, there are limited data evaluating the treatment effect on esophageal dilatation. This study aimed to assess the effect achalasia treatment on esophageal dilatation and the effect of esophageal width reduction ("recoil") on clinical outcomes. METHODS: Patients with type I or type II achalasia that completed high-resolution manometry (HRM), functional lumen imaging probe (FLIP), and timed barium esophagram (TBE) pre and post treatment were included. Esophageal width was measured using TBE. Focused subgroup analysis was performed on patients with normal posttreatment EGJ opening on FLIP. Good clinical outcomes were defined as barium column height of <5 cm at 5 min and Eckardt Score ≤3. KEY RESULTS: Sixty-nine patients (41% type I and 59% type II) were included. Esophageal width decreased from pre to post treatment mean (SD) 4.2 (1.3) cm-2.8 (1.2) cm; p < 0.01. In the normal post treatment EGJ opening subgroup, esophageal width was less in patients with good TBE outcome compared to poor outcome mean (SD) 2.2 (0.7) cm versus 3.2 (1.4) cm (p < 0.01), but did not differ in good versus poor symptomatic outcome groups. Esophageal width recoil >25% posttreatment was associated with a greater rate of good TBE outcome (71% vs. 50%, p = 0.04) and good symptomatic outcome (88% vs. 50%; p = 0.04). CONCLUSIONS AND INFERENCES: Esophageal recoil was associated with good achalasia treatment outcome in patients without posttreatment EGJ obstruction. This suggests that mechanical properties of the esophageal wall, likely associated with tissue remodeling, play a role in clinical outcomes following achalasia treatment.

ABSTRACT

BACKGROUND & AIMS: Chronic inflammation of eosinophilic esophagitis (EoE) results in progressive, fibrostenotic remodeling of the esophageal wall. This study aimed to demonstrate objective changes in esophageal distensibility relative to duration of EoE disease using a functional lumen imaging probe (FLIP). METHODS: Adult patients with EoE who completed a 16-cm FLIP protocol during endoscopy were evaluated in a cross-sectional study. FLIP analysis focused on distensibility plateau (DP) of the esophageal body. The time from onset of symptoms to time of endoscopy with FLIP was assessed, as was time from symptom onset to EoE diagnosis (ie, diagnostic delay). RESULTS: A total of 171 patients (mean age 38 ± 12 years; 31% female) were included; the median symptom duration was 8 (interquartile range, 3-15) years and diagnostic delay was 4 (interquartile range, 1-12) years. At the time of endoscopy with FLIP, there were 54 patients (39%) in histologic remission (<15 eosinophils per high-power field [eos/hpf]). Symptom duration and diagnostic delay were negatively correlated with DP (rho = -0.326 and -0.309; P values < .001). Abnormal esophageal distensibility (DP ≤17 mm) was more prevalent with increased duration of symptoms (P < .004): 23% at <5 years to 64% at ≥25 years. When stratifying the cohort based on mucosal eosinophil density, patients with ≥15 eos/hpf had significantly lower DP with greater symptom duration (P = .004), while there was not a significant difference among patients with <15 eos/hpf (P = .060). CONCLUSIONS: Esophageal distensibility objectively measured with FLIP was reduced in EoE patients with greater symptom duration and diagnostic delay. This supports that EoE is a progressive, fibrostenotic disease and that FLIP may be a useful tool to monitor disease progression in EoE.

ABSTRACT

BACKGROUND AND AIMS: Some achalasia patients exhibit esophageal contractile activity on follow-up after treatment, yet its importance remains unclear. We aimed to identify factors associated with presence of contractility after treatment and to assess its impact on timed barium esophagram (TBE) and clinical outcomes. METHODS: Patients with type I or II achalasia on baseline high-resolution manometry (HRM) who completed HRM, TBE, and functional lumen imaging probe (FLIP) after treatment were retrospectively identified. Contractility was defined on post-treatment HRM as presence of at least 1 supine swallow with DCI ≥100 mmHg s cm. KEY RESULTS: One hundred twenty-two patients were included (mean age 48 ± 17 years, 50% female). At follow-up evaluation after treatment (54% peroral endoscopic myotomy, 24% pneumatic dilation, 22% laparoscopic Heller myotomy), 61 (50%) patients had contractility on HRM. Patients with contractility (compared to those without) more frequently had type II achalasia (84% vs 57%, p = 0.001) and a post-treatment normal EGJ opening classification on FLIP (69% vs 49%; p < 0.001). In the subgroup of patients with post-treatment integrated relaxation pressure <15 mmHg and normal EGJ opening on FLIP (n = 53), those with contractility had a lower median column height on TBE at 1 min (4 vs 7 cm, p = 0.002) and 5 min (0 vs 5 cm, p = 0.001). In patients with "abnormal" EGJ metrics, patients with contractility showed lower symptom scores (median Eckardt score 2 vs 3, p = 0.03). CONCLUSIONS & INFERENCES: Occurring more frequently in type II achalasia, and if adequate EGJ opening is achieved after treatment, esophageal contractility may contribute to improved esophageal emptying and improved symptoms in non-spastic achalasia. Preservation of esophageal body muscle could improve outcomes in these patients.

ABSTRACT

BACKGROUND: The esophageal response to stepwise distension during the functional lumen imaging probe (FLIP) Panometry study often parallels high-resolution manometry (HRM) motility diagnoses. This study aimed to describe the changes in FLIP metrics during FLIP emptying, that is, reduced volume distension. METHODS: Adult patients who completed FLIP and HRM for esophageal motility evaluation were included. Esophagogastric junction (EGJ) opening parameters were assessed during stepwise FLIP filling to volumes of 60 mL ("filling 60 mL"), then 70 mL, and then back to 60 mL ("emptying 60 mL"). HRM studies were analyzed per Chicago classification version 4.0 (CCv4.0). KEY RESULTS: Among 265 patients included, HRM/CCv4.0 diagnoses included achalasia in 80 patients (30%), normal motility in 70 (26%), and ineffective esophageal motility (IEM) in 43 (16%). EGJ-distensibility index (DI) and EGJ diameter were greater during emptying 60 mL than filling 60 mL in achalasia, normal motility, and IEM (p values <0.002). If applying the emptying 60 mL EGJ-DI (vs. filling 60 mL EGJ-DI), EGJ opening classification changed from reduced EGJ opening to borderline EGJ opening in 31% of achalasia patients and in 2% of patients with normal motility or IEM. EGJ opening classification was unchanged in 69% achalasia and 96% of normal motility/IEM. CONCLUSIONS AND INFERENCES: This study suggests that isotonic or auxotonic relaxation of the lower esophageal sphincter occurs with reduced volume distension in patients with achalasia and normal motility. The study also supports the importance of utilizing a standardized FLIP motility study protocol (i.e., controlled, stepwise filling to 50 mL, 60 mL, then 70 mL) to provide reliable and generalizable FLIP metrics to facilitate diagnosis of esophageal motility disorders.

ABSTRACT

BACKGROUND: Panesophageal pressurization (PEP) defines type II achalasia on high-resolution-manometry (HRM) but some patients exhibit spasm after treatment. The Chicago Classification (CC) v4.0 proposed high PEP values as predictor of embedded spasm, yet supportive evidence is lacking. METHODS: Fifty seven type II achalasia patients (47 ± 18 years, 54% males) with HRM and LIP Panometry before and after treatment were retrospectively identified. Baseline HRM and FLIP studies were analyzed to identify factors associated with post-treatment spasm, defined on HRM per CC v4.0. RESULTS: Seven patients (12%) had spasm following treatment (peroral endoscopic myotomy 47%; pneumatic dilation [PD] 37%; laparoscopic Heller myotomy 16%). At baseline, greater median maximum PEP pressure (MaxPEP) values on HRM (77 vs 55 mmHg, p = 0.045) and spastic-reactive contractile response pattern on FLIP (43% vs 8%, p = 0.033) were more common in patients with post-treatment spasm while absent contractile response on FLIP was more common in patients without spasm (14% vs 66%, p = 0.014). The strongest predictor of post-treatment spasm was the percentage of swallows with MaxPEP ≥70 mmHg (best cut-off: ≥30%), with AUROC of 0.78. A combination of MaxPEP <70 mmHg and FLIP 60 mL pressure < 40 mmHg identified patients with lower rates of post-treatment spasm (3% overall, 0% post-PD) compared to those with values above these thresholds (33% overall, 83% post-PD). CONCLUSIONS: High maximum PEP values, high FLIP 60 mL pressures and contractile response pattern on FLIP Panometry prior to treatment identified type II achalasia patients more likely to exhibit post-treatment spasm. Evaluating these features may guide personalized patient management.

ABSTRACT

Barrett's esophagus (BE) occurs in 5-15% of patients with gastroesophageal reflux disease (GERD). While acid suppressive therapy is a critical component of BE management to minimize the risk of progression to esophageal adenocarcinoma, surgical control of mechanical reflux is sometimes necessary. Magnetic sphincter augmentation (MSA) is an increasingly utilized anti-reflux surgical therapy for GERD. While the use of MSA is listed as a precaution by the United States Food and Drug Administration, there are limited data showing effective BE regression with MSA. MSA offers several advantages in BE including effective reflux control, anti-reflux barrier restoration and reduced hiatal hernia recurrence. However, careful patient selection for MSA is necessary.

ABSTRACT

BACKGROUND & AIMS: An association of eosinophilic esophagitis (EoE) with esophageal dysmotility has been described, however, the related mechanism remains unclear. We aimed to evaluate clinical and physiologic characteristics, including esophageal distensibility, associated with secondary peristalsis in patients with EoE. METHODS: A total of 199 consecutive adult patients with EoE (age, 18-78 y; 32% female) who completed a 16-cm functional luminal imaging probe (FLIP) during endoscopy were evaluated in a cross-sectional study. FLIP panometry contractile response (CR) patterns were classified as normal CR or borderline CR if antegrade contractions were present, and abnormal CRs included impaired/disordered CR, absent CR, or spastic-reactive CR. The distensibility plateau of the esophageal body and esophagogastric junction distensibility was measured with FLIP. RESULTS: FLIP CR patterns included 68 (34%) normal CR, 65 (33%) borderline CR, 44 (22%) impaired/disordered CR, 16 (8%) absent CR, and 6 (3%) spastic-reactive CR. Compared with normal CRs, abnormal CRs more frequently had reduced esophageal distensibility (distensibility plateau <17 mm in 56% vs 32%), greater total EoE reference scores (median, 5; interquartile range [IQR], 3-6 vs median, 4; IQR, 3-5) with more severe ring scores, and a greater duration of symptoms (median, 10 y; IQR, 4-23 y vs median, 7 y; IQR, 3-15 y). Mucosal eosinophil density, however, was similar between abnormal CRs and normal CRs (median, 34 eosinophils/high-power field [hpf]; IQR, 14-60 eosinophils/hpf vs median, 25 eosinophils/hpf; IQR, 5-50 eosinophils/hpf). CONCLUSIONS: Although normal secondary peristalsis was observed frequently in this EoE cohort, abnormal esophageal CRs were related to EoE disease severity, especially features of fibrostenosis. This study evaluating secondary peristalsis in EoE suggests that esophageal wall remodeling, rather than eosinophilic inflammatory intensity, was associated with esophageal dysmotility in EoE.

ABSTRACT

Endoscopic eradication therapy (EET) is recommended for patients with Barrett's esophagus (BE)-associated neoplasia and is effective in achieving complete eradication of intestinal metaplasia (CE-IM). However, BE that is refractory to EET, defined as partial or no improvement in dysplasia after less than or equal to 3 ablative sessions, and the development of recurrence post-EET is not uncommon. Identification of refractory BE or recurrent intestinal metaplasia should prompt esophageal physiologic testing and modification of antireflux strategy, as appropriate. In patients who ultimately fail standard EET despite optimization of reflux control, salvage EET with alternate modalities may need to be considered.

ABSTRACT

Background and study aims Critically ill patients may require endoscopic retrograde cholangiopancreatography (ERCP) but performing ERCP in the intensive care unit (ICU) poses logistic and technical challenges. There are no data on ICU patients undergoing ERCP in the endoscopy suite. The primary aim of this study was to report outcomes, including safety, when ERCP in critically ill patients is performed in the endoscopy suite. Patients and methods We queried our institutional endoscopy database to identify all ICU patients who underwent ERCP at a single academic medical center from 04/01/2010 to 11/30/2017. Only patients admitted to an ICU prior to ERCP were included. Results Of 7,218 ERCPs performed during the study period, 260 ERCPs (3.6 %) were performed in 231 ICU patients (mean age 61y; 53 % male); nearly all ICU patient ERCPs (n = 258; 99 %) occurred in the endoscopy suite. ERCP indications included cholangitis (50 %), post-liver transplant cholestasis (15 %), and bile leak (10 %). All ERCPs were performed with anesthesiology, most with general anesthesia (60 %) and in the prone position (60 %). Most patients (73 %) had sepsis. Prior to ERCP, 17 % of patients required vasopressors; vasopressors were begun during ERCP in 4 %. The cannulation success rate was 95 % (94 % in native papillae). Adverse events occurred in 9 % (n = 23) of cases with post-ERCP pancreatitis most common. No patients died during or within 24 hours of ERCP. Mortality at 30 days was 16 %, all attributed to underlying disease. Conclusions When advanced ventilatory and hemodynamic support is available, critically ill patients can safely and effectively undergo ERCP in the endoscopy suite.

ABSTRACT

Vasoactive intestinal polypeptide-secreting tumors (VIPoma) are a rare pancreatic neuroendocrine tumor that can cause chronic diarrhea with 1 case per 10 million people per year. Diagnosis is made based on a combination of laboratory evaluation (serum VIP level), imaging findings (functional positron emission tomography-computed tomography [PET-CT]), and histological analysis (chromogranin A stain). We present a case of a male with 6 months of diarrhea and malaise who was found to have significant kidney injury and hypokalemia requiring admission to the medical intensive care unit. Subsequent laboratory evaluation while admitted eventually showed a low stool osmotic gap (-11 mOsm/kg) consistent with secretory diarrhea, in addition to significantly elevated VIP levels at 940 pg/mL (normal <75). Cross-sectional imaging with functional Gallium-68 dotatate PET-CT confirmed metastatic functional neuroendocrine tumor indicative of a VIPoma. Pathology on subsequent metastatic liver lesion aspiration was consistent with a well-differentiated VIPoma, and symptoms dramatically improved following initiation of octreotide therapy.

ABSTRACT

BACKGROUND AND OBJECTIVES: Lymph node evaluation recommendations for extremity soft tissue sarcoma (ESTS) are absent from national guidelines. Our objectives were (1) to assess rates and predictors of nodal evaluation, and (2) to assess rates and predictors of nodal metastases. METHODS: ESTS patients from the National Cancer Data Base (2000-2009) were assessed, and regression models were used to identify factors associated with nodal evaluation and metastases. RESULTS: Of 27,536 ESTS patients, 1,924 (7%) underwent nodal evaluation, and of these, 290 (15%) had nodal metastases. Nodal evaluation was most frequently performed for rhabdomyosarcoma (15.6%), angiosarcoma (10.0%), clear cell sarcoma (39.3%), epithelioid sarcoma (28.1%), and synovial sarcoma (9.3%). On multivariable analysis, factors associated with nodal evaluation included histologic subtype, tumor size, and grade. Nodal metastasis rates were highest among patients with rhabdomyosarcoma (32.1%), angiosarcoma (24.1%), clear cell sarcoma (27.7%), and epithelioid sarcoma (31.8%). On multivariable analysis, factors associated with nodal metastases included histologic subtype, tumor size, and grade. CONCLUSIONS: Nodal evaluation rates are highest among certain expected subtypes but are generally low. However, nodal metastasis rates for many histologic subtypes in patients selected for lymph node evaluation may be higher than previously reported. Multi-institutional studies should address nodal evaluation for ESTS.
