High technical and clinical success was obtained with TAE in patients with bleeding duodenal ulcer after failure of endoscopic treatment. TAE appears to be a treatment alternative to surgery in this group of patients.

BackgroundMalignant gastric outlet obstruction (GOO) is commonly seen in patients with advanced gastric-, pancreatic-, duodenal, hepatobiliary or metastatic malignancies. Ten to 25% of patients with pancreatic cancer will develop duodenal obstruction during the course of the disease. Duodenal stenting with self-expandable metal stents is an alternative treatment to surgical bypass procedures. Our aim was to review the published literature regarding treatment of malignant GOO with stents to reveal whether the information provided is sufficient to evaluate the clinical effects of this treatmentMethodsA literature search from 2000 – 2007 was conducted in Pub Med, Embase, and Cochrane library, combining the following search terms: duodenal stent, malignant duodenal obstruction, gastric outlet obstruction, SEMS, and gastroenteroanastomosis.All publications presenting data with ≥ 15 patients and only articles written in English were included and a review focusing on the following parameters were conducted: 1) The use of graded scoring systems evaluating clinical success; 2) Assessment of Quality of life (QoL) before and after treatment; 3) Information on stent-patency; 4) The use of objective criteria to evaluate the stent effect.Results41 original papers in English were found; no RCT's. 16 out of 41 studies used some sort of graded scoring system. No studies had objectively evaluated QoL before or after stent treatment, using standardized QoL-questionnaires, 32/41 studies reported on stent patency and 9/41 performed an oral contrast examination after stent placement. Objective quantitative tests of gastric emptying had not been performed.ConclusionAvailable reports do not provide sufficient relevant information of the clinical outcome of duodenal stenting. In future studies, these relevant issues should be addressed to allow improved evaluation of the effect of stent treatment.

Objectives. Achalasia is a primary motility disorder of the esophagus characterized by aperistalsis and failure of lower esophageal sphincter (LES) relaxation. Treatment of achalasia aims at reducing LES pressure. The common treatment modalities are laparoscopic Heller myotomy and pneumatic dilatation, but during the last decade, a promising treatment, per oral endoscopic myotomy (POEM), has been introduced. The aim of the present study was to perform a systematic review of the literature to assess the outcome of POEM in treatmentnaive patients. Materials and Methods. A systematic literature search in PubMed, Embase and Cochrane databases was performed using the terms 'Achalasia AND (POEM OR peroral endoscopic myotomy OR per-oral endoscopic myotomy)'. Inclusion criteria were: original article; English language; n ≥ 20 with ≥ 90 % treatment-naive patients; follow-up ≥ 3 months; and outcome evaluation of POEM including symptom score and objective tests. Exclusion criteria were: reviews and metaanalyses; pediatric data; duplicates; and articles with overlapping data material. Results. Of the 1641 articles identified, seven were included. The included studies all reported a short term clinical success of > 90%. Clinical success including post POEM reflux was mainly estimated by symptom scorings. There were few procedure-related complications. Conclusions. The studies of treatment-naive patients indicate a high rate of clinical success. Nevertheless, a more systematic and standardized evaluation is recommended to improve the reports on outcome of POEM. The follow-up rate should be high and the evaluation protocol should include both symptom scoring and objective testing with predefined treatment goals.

Background and aims Peroral endoscopic myotomy (POEM) is an established therapy for achalasia, but outcome evaluation has often been limited to Eckardt score (ES). The present study was aimed to improve knowledge about outcome evaluation and predictive outcome factors by performing a comprehensive objective evaluation of achalasia patients treated by POEM. Methods This single centre prospective study reports outcome data 12 months after POEM in treatment-naive achalasia patients. A predefined follow-up protocol included ES, high resolution manometry, 24-h pH measurement, upper endoscopy and timed barium esophagogram (TBE). Univariate and multivariate regression analyses were performed to analyze association between post-POEM variables and identify predictive factors for objective outcome. Results Fifty patients were included with a drop-out rate of <5%. ES, lower oesophageal sphincter pressures, TBE heights and maximal oesophageal diameter were all reduced after POEM ( p < .001), and 28% (13/47) of the patients had a positive 24-h pH registration. An oesophageal diameter >3 cm after POEM was associated with treatment failure assessed by ES ( p = .04) and TBE ( p = .03). Advanced achalasia stage ( p = .02) and long symptom duration ( p = .04) were identified as independent predictive factors for poor outcome assessed by TBE. Conclusions The present study confirms that POEM is an efficient therapy for achalasia. The comprehensive objective evaluation after POEM demonstrates that long symptom duration and major changes in oesophageal anatomy at diagnosis imply poor treatment outcome, and a post-POEM dilated oesophagus is associated with treatment failure. Key messages Peroral endoscopic myotomy (POEM) is established as a safe and effective therapy for achalasia. Timed barium esophagogram offers objective variables that are valuable in treatment response evaluation. Advanced achalasia stage and long symptom duration are predictive factors for poor objective treatment response after POEM.

The present study demonstrated that treatment with SEMS results in improved gastric emptying in most patients with GOO and a corresponding reduction in self-reported obstruction symptoms. However, survival and emptying were not related. The present findings provide further evidence that treatment with stents is an effective palliative treatment in patients with GOO.

Long-term outcome after palliative treatment with SEMS for malignant GI and biliary obstruction shows that 70% had a patent stent until death, and that most reobstructions could be solved endoscopically. Hospital readmissions were mainly related to progression of the underlying cancer disease.

BackgroundThe clinical effect of stent treatment has been evaluated by mainly physicians; only a limited number of prospective studies have used patient-reported outcomes for this purpose. The aim of this work was to study the clinical effect of self-expanding metal stents in treatment of malignant gastrointestinal obstructions, as evaluated by patient-reported outcomes, and compare the rating of the treatment effect by patients and physicians.MethodsBetween November 2006 and April 2008, 273 patients treated with SEMS for malignant GI and biliary obstructions were recruited from nine Norwegian hospitals. Patients and physicians assessed symptoms independently at the time of treatment and after 2 weeks using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire supplemented with specific questions related to obstruction.ResultsA total of 162 patients (99 males; median age = 72 years) completed both assessments and were included in the study. A significant improvement in the mean global health score was observed after 2 weeks (from 9 to 18 on a 0–100 scale, P < 0.03) for all stent locations. Both patients and physicians reported a significant reduction in all obstruction-related symptoms (>20 on the 0–100 scale, P < 0.006) after SEMS treatment. The physicians reported a larger mean improvement in symptoms than did the patients, mainly because they reported more severe symptoms before treatment.ConclusionSEMS treatment is effective in relieving symptoms of malignant GI and biliary obstruction, as reported by patients and physicians. The physicians, however, reported a larger reduction in obstructive symptoms than did the patients. A prospective assessment of patient-reported outcomes is important in evaluating SEMS treatment.

Background and study aims Knowledge on quality of life (QoL) in achalasia and QoL improvements after peroral endoscopic myotomy (POEM) is limited. The clinical role of QoL in achalasia follow-up has not been evaluated. The present study aimed to examine QoL in achalasia patients before and after POEM and assess associations between QoL, Eckardt score (ES) and objective results. Patients and methods This is a single center prospective study of treatment-naive achalasia patients with 12 months follow-up after POEM including manometry, upper endoscopy, 24 hour pH registration and timed barium esophagogram. QoL data were registered using European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire (QLQ-C30) and esophageal module (QLQ-OES18). Comparison with a reference population was performed to assess impact of achalasia on QoL and effect of therapy. Mixed models for repeated measures were applied. Results Fifty patients (26 females) with a median age of 47 years (18-76) were included. Before treatment, all QoL domains were significantly impaired compared with an age- and gender-adjusted reference population (p < 0.05). No significant QoL-differences were found after POEM, except for fatigue and nausea/vomiting. Clinically relevant QoL-improvement was observed in ≥ 50 % of the patients in all QoL domains, except for physical and role functioning. QoL was significantly associated with ES (p < 0.05) but not with objective results. Conclusion Achalasia is associated with severe QoL impairment. Following POEM, a significant and clinically relevant QoL improvement is observed. QoL is associated with ES, but not with objective results after POEM.
