RESUMO

BACKGROUND: Endoscopic management is the first-line therapy for post-liver-transplant anastomotic strictures. Although the optimal duration of treatment with plastic stents has been reported to be 8-12 months, data on safety and duration for metal stents in this setting is scarce. Due to limited access to endoscopic retrograde cholangiopancreatography (ERCP) during the coronavirus disease 2019 pandemic in our centre, there was a change in practice towards increased usage and length-of-stay of the Kaffes biliary intraductal self-expanding stent in patients with suitable anatomy. This was mainly due to the theoretical benefit of Kaffes stents allowing for longer indwelling periods compared to the traditional plastic stents. AIM: To compare the safety and efficacy profile of different stenting durations using Kaffes stents. METHODS: Adult liver transplant recipients aged 18 years and above who underwent ERCP were retrospectively identified during a 10-year period through a database query. Unplanned admissions post-Kaffes stent insertion were identified manually through electronic and scanned medical records. The main outcome was the incidence of complications when stents were left indwelling for 3 months vs 6 months. Stent efficacy was calculated via rates of stricture recurrence between patients that had stenting courses for ≤ 120 d or > 120 d. RESULTS: During the study period, a total of 66 ERCPs with Kaffes insertion were performed in 54 patients throughout their stenting course. In 33 ERCPs, the stent was removed or exchanged on a 3-month interval. No pancreatitis, perforations or deaths occurred. Minor post-ERCP complications were similar between the 3-month (abdominal pain and intraductal migration) and 6-month (abdominal pain, septic shower and embedded stent) groups - 6.1% vs 9.1% respectively, P = 0.40. All strictures resolved at the end of the stenting course, but the stenting course was variable from 3 to 22 months. The recurrence rate for stenting courses lasting for up to 120 d was 71.4% and 21.4% for stenting courses of 121 d or over (P = 0.03). There were 28 patients that were treated with a single ERCP with Kaffes, 21 with removal after 120 d and 7 within 120 d. There was a significant improvement in stricture recurrence when the Kaffes was removed after 120 d when a single ERCP was used for the entire stenting course (71.0% vs 10.0%, P = 0.01). CONCLUSION: Utilising a single Kaffes intraductal fully-covered metal stent for at least 4 months is safe and efficacious for the management of post-transplant anastomotic strictures.

RESUMO

Background and Aim: Obtaining endoscopic biopsies from the ampulla of Vater is important for the diagnosis of lesions that are suspicious for neoplasia. The clinical safety profile is not well defined in the literature. Our aim was to evaluate the procedure-related readmission rate and complications from ampullary biopsy in patients undergoing duodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP). Methods: A retrospective data analysis was performed on adult patients at Austin Hospital who underwent ampullary biopsies between 1 January 2010 and 1 March 12022. Medical records were identified using pathology databases. The electronic health record was reviewed for baseline characteristics including demographics, date, indication for ampullary biopsy, procedure type (duodenoscopy or ERCP), and procedural associated interventions during ERCP. Readmissions to the Austin Emergency Department within 30 days following the biopsy were identified, and complications were noted. Results: A total of 506 records were reviewed and 246 episodes of ampullary biopsy met the inclusion criteria. The procedure-related readmission rate for all episodes was 6.1%, which included pain (3.3%), pancreatitis (2.0%), cholangitis (1.6%), and bleeding (0.8%). Ampullary biopsies with ERCP had a procedure-related readmission rate of 8.4%, whereas ampullary biopsies without ERCP had a rate of 2.2%. Increased readmissions and complications were associated with male sex (P = 0.01 and P = 0.05, respectively). There was no association between the number of biopsies taken and complications. Conclusion: Performing an ampullary biopsy without an associated ERCP carries a low rate of clinical complications and procedure-related readmissions. The combination of ERCP and ampullary biopsy increases the risk four-fold.

RESUMO

Background and Aim: During COVID-19, restrictions to elective endoscopy were introduced worldwide. A reduction in procedures may impact trainees' endoscopy learning. This study aims to assess Australian advanced gastroenterology and general surgery trainees' self-perceived efficacy and knowledge in endoscopy during the pandemic. Methods: All Australian gastroenterology and general surgery trainees in their last 2 years of accredited training were invited to participate through email (2020-2021 and 2021-2022 training cycles). The primary outcome was to assess trainees' self-efficacy and knowledge regarding gastrointestinal endoscopy. Secondary outcomes included subgroup analysis between gastroenterology and general surgery trainees. Self-perceived efficacy was assessed with Likert-scale questions on 20 endoscopy procedures and knowledge was assessed through 21 endoscopy-related multiple choice questions. Results: Eighty-one trainees responded to a self-efficacy questionnaire and 77 responded to the knowledge questionnaire. Over 90% of the trainees were confident or extremely confident in diagnostic endoscopy, but only half demonstrated similar efficacy for therapeutic endoscopy. The efficacy for basic endoscopy procedures was higher for gastroenterology trainees (64.0% vs 51.1%, P < 0.001). Last-year trainee achievement of conjoint committee requirements for upper gastrointestinal endoscopy was achieved in 95.8% of gastroenterology trainees versus 22.2% of surgical trainees (P < 0.001). The median score on the knowledge questionnaire was also higher for the gastroenterology subset (90.5% vs 71.4%, P < 0.001). Conclusion: During COVID-19, endoscopy trainees' self-efficacy in endoscopic diagnostic procedures was achieved for most trainees. The differences in self-perceived efficacy and knowledge between gastroenterology and surgical trainees may be reflective of the different opportunities for learning between the two groups.

RESUMO

BACKGROUND: Anaesthetic care during upper gastrointestinal (GI) endoscopy has the unique challenge of maintaining ventilation and oxygenation via a shared upper airway. Supplemental oxygen is recommended by international society guidelines, however, the optimal route or rate of oxygen delivery is not known. Various oxygen delivery devices have been investigated to improve oxygenation during upper GI endoscopy, however, these are limited by commercial availability, costs and in some cases, the expertise required for insertion. Anecdotally at our centre, higher flows of supplemental oxygen can safely be delivered via an oxygenating mouthguard routinely used during upper GI endoscopic procedures. AIM: To assess the incidence of hypoxaemia (SpO2 < 90%) in patients undergoing upper GI endoscopy receiving supplemental oxygen using an oxygenating mouthguard at 20 L/min flow compared to standard nasal cannula (SNC) at 2 L/min flow. METHODS: A single centre, prospective, randomised clinical trial at two sites of an Australian tertiary hospital between October 2020 and September 2021 was conducted. Patients undergoing elective upper gastrointestinal endoscopy under deep sedation were randomised to receive supplemental oxygen via high-flow via oxygenating mouthguard (HFMG) at 20 L/min flow or SNC at 2 L/min flow. The primary outcome was the incidence of hypoxaemia of any duration measured by pulse oximetry. Intraprocedural-related, procedural-related, and sedation-related adverse events and patient-reported outcomes were also recorded. RESULTS: Three hundred patients were randomised. Eight patients were excluded after randomisation. 292 patients were included in the intention-to-treat analysis. The incidence of hypoxaemia was significantly reduced in those allocated HFMG. Six patients (4.4%) allocated to HFMG experienced an episode of hypoxaemia, compared to thirty-four (22.1%) patients allocated to SNC (P value < 0.001). No significant difference was observed in the rates of adverse events or patient-reported outcome measures. CONCLUSION: The use of HFMG offers a novel approach to reducing the incidence of hypoxaemia during short upper gastrointestinal endoscopic procedures in low-risk patients undergoing deep sedation.

RESUMO

Background and study aims Refractory variceal bleeding is associated with high mortality in patients with chronic liver disease. A fully-covered self-expanding metal stent (SEMS) has been reported to have excellent rates of technical success and initial bleeding control; however, studies to date are small and limited to Europe and Asia. Our aim was to evaluate the efficacy and safety of this SEMS for control of refractory variceal bleeding (VB). Patients and methods A retrospective analysis was undertaken of all patients who received the SX-ELLA Danis SEMS for management of VB at 9 tertiary centers across Australia and New Zealand. A total of 32 SEMS had been deployed in 30 patients (median age 53.3). Results Technical success of SEMS placement was achieved in 100 % of cases, resulting in immediate control of bleeding across 31 of 32 cases (96.9 %). Re-bleeding with SEMS in situ occurred in three of 32 cases (9.4 %). Mean SEMS in-dwelling time was 6.4 days. Delayed SEMS migration occurred in 6.3 % of cases. Interventional radiological therapy for management of varices within 6 weeks was performed in 12 of 30 patients (40 %). Death with SEMS in situ occurred in seven of 30 patients (23.3 %). Seven-day bleeding-related mortality was 16.7 %, 14-day mortality 23.3 %, and 6-week mortality 33.3 %. Three of 30 patients (10 %) received orthotopic liver transplantation following SEMS insertion, including two patients within 6 weeks. Conclusions SX-Danis Ella SEMS is highly effective for immediate control of refractory VB and bridging to definitive therapy because it has excellent technical success rates, appears to be relatively easy to use, and has low rates of serious adverse events.

RESUMO

BACKGROUND AND AIMS: In symptomatic patients with ileoanal pouches, pouchoscopy is needed for accurate diagnosis but is invasive. We aimed to assess the utility of non-invasive gastrointestinal ultrasound and faecal calprotectin in ileoanal pouch patients. METHODS: Patients with an ileoanal pouch were consecutively enrolled in this cross-sectional study from clinics in Victoria, Australia. The pouchitis disease activity index was used as a reference standard. Video-recorded pouchoscopies were reviewed by three gastroenterologists. Pouch, pre-pouch, and cuff biopsies were reviewed by a single pathologist. Ultrasound was performed by a single gastroenterologist transabdominally and transperineally. Faecal calprotectin was measured from morning stool samples. All examiners were blinded to patients' clinical history. RESULTS: A total of 44 participants had a pouchoscopy, of whom 43 had a faecal calprotectin test and 42 had an ultrasound; 17 had pouchitis, 15 had pre-pouch ileitis, and 16 had cuffitis. Pouch wall thickness of <3 mm was 88% sensitive in excluding pouchitis, and pouch wall thickness of ≥4 mm was 87% specific in diagnosing pouchitis. Transabdominal ultrasound had good utility [area under the curve: 0.78] in diagnosing moderate-severe pre-pouch ileitis. Transperineal ultrasound had good utility for the diagnosis of pouchitis [area under the curve: 0.79]. Faecal calprotectin differentiated inflammatory from non-inflammatory pouch disorders, such as irritable pouch syndrome, with an area under the curve of 0.90. Faecal calprotectin <100 µg/g ruled out inflammatory pouch disorders with a sensitivity of 94%. CONCLUSIONS: Faecal calprotectin and ultrasound are accurate and complementary tests to diagnose and localise inflammation of the ileoanal pouch. Prospective studies are needed to validate proposed sonographic indices and calprotectin levels.

RESUMO

BACKGROUND AND AIMS: Currently used endoscopic items for the assessment of pouchitis and cuffitis have deficiencies in reliability and validation. We assessed the reliability and accuracy of new endoscopic items for pouchitis and of the Ulcerative Colitis Endoscopic Index of Severity [UCEIS] for cuffitis. METHODS: Three new endoscopic items were assessed and included in the Monash pouchitis endoscopic subscore: bleeding [absent/contact/spontaneous]; erosions [absent/<10/≥10]; and ulceration [absent/<10%/≥10%]. Three raters evaluated 44 pouchoscopy videos in duplicates, in random order. Intra- and inter-rater reliability of all endoscopic items and UCEIS were assessed. Clinical and histological pouchitis disease activity index [PDAI] subscores were also assessed and faecal calprotectin was measured. RESULTS: All three Monash endoscopic items had substantial intra-rater reliability with intraclass correlation coefficients [ICCs] >0.61 [95% CI >0.61], compared with only ulcers from the currently used PDAI endoscopic subscore, but inter-rater reliability was only substantial for ulceration and no better than those of the currently used endoscopic items. The Monash endoscopic subscore had a strong positive correlation with the reference standard global endoscopic lesion severity r = 0.80 [95% CI 0.80-0.80] and the reference standard PDAI endoscopic subscore r = 0.70 [95% CI 0.67-0.73], which was higher than the correlation observed for the currently used PDAI endoscopic subscore. The UCEIS had substantial intra-rater reliability, but only fair inter-rater reliability and poor diagnostic performance for cuffitis. CONCLUSIONS: The Monash endoscopic items, and endoscopic subscore they generate, have enhanced overall performance compared with the currently used PDAI items and subscore. Further validation and responsiveness to change in disease state are indicated.

RESUMO

BACKGROUND AND AIM: Cholecystectomy and endoscopic retrograde cholangiopancreatography are the gold standard for managing acute cholecystitis and malignant biliary obstruction, respectively. Recent advances in therapeutic endoscopic ultrasound (EUS) have provided alternatives for managing patients in whom these approaches fail, namely, EUS-guided gallbladder drainage (EUS-GB) and EUS-guided bile duct drainage (EUS-BD). We aimed to assess the technical and clinical success of these techniques in the largest multicenter cohort published to date. METHODS: A retrospective, multicenter, observational study involving 17 centers across Australia and New Zealand was conducted. All patients who had EUS-GB or EUS-BD performed in a participating center using a lumen apposing metal stent between 2016 and 2020 were included. Primary outcome was technical success, defined as intra-procedural successful drainage. Secondary outcomes included clinical success and 30-day mortality. RESULTS: One hundred and fifteen patients underwent EUS-GB (n = 49) or EUS-BD (n = 66). EUS-GB was technically successful in 47 (95.9%) while EUS-BD was successful in 60 (90.9%). All failed cases were due to maldeployment of the distal flange outside of the targeted lumen. Clinical success of EUS-GB was achieved in 39 (79.6%). No patients required subsequent cholecystectomy. Clinical success of EUS-BD was achieved in 52 (78.8 %). Thirty-day mortality was 14.3% for EUS-GB and 12.1% for EUS-BD. CONCLUSIONS: EUS-guided gallbladder drainage and EUS-BD are promising alternatives for managing nonsurgical candidates with cholecystitis and malignant biliary obstruction following failed endoscopic retrograde pancreatography. Both techniques delivered high technical success with acceptable clinical success. Further research is needed to investigate the gap between technical and clinical success.

RESUMO

BACKGROUND: Image-guided radiotherapy (IGRT) has significantly improved the precision in which radiotherapy is delivered in cancer treatment. Typically, IGRT uses bony landmarks and key anatomical structures to locate the tumor. Recent studies have demonstrated the feasibility of peri-tumor fiducials in enabling even more accurate delineation of target and normal tissue. The use of gold coils as fiducials in gastrointestinal tumors has been extensively studied. However, placement requires expertise and specialized endoscopic ultrasound equipment. This article reports the long-term outcomes of using a standard gastroscopy to inject liquid fiducials for the treatment of oesophageal and gastric tumors with IGRT. AIM: To assess the long-term outcomes of liquid fiducial-guided IGRT in a cohort of oesophageal and gastric cancer patients. METHODS: A retrospective cohort study of consecutive adults with Oesophagogastric cancers referred for liquid fiducial placement before definitive/neo-adjuvant or palliative IGRT between 2013 and 2021 at a tertiary hospital in Melbourne, Australia was conducted. Up to four liquid fiducials were inserted per patient, each injection consisting of 0.2-0.5mL of a 1:1 mixture of iodized oil (Lipiodol; Aspen Pharmacare) and n-butyl 2-cyanoacrylate (Histoacryl®; B. Braun). A 23-gauge injector (Cook Medical) was used for the injection. All procedures were performed by or under the supervision of a gastroenterologist. Liquid fiducial-based IGRT (LF-IGRT) consisted of computer-assisted direct matching of the fiducial region on cone-beam computerised tomography at the time of radiotherapy. Patients received standard-IGRT (S-IGRT) if fiducial visibility was insufficient, consisting of bone match as a surrogate for tumor position. Radiotherapy was delivered to 54Gy in 30 fractions for curative patients and up to 45Gy in 15 fractions for palliative treatments. RESULTS: 52 patients were referred for liquid fiducial placement within the study period. A total of 51 patients underwent liquid fiducial implantation. Of these a total of 31 patients received radiotherapy. Among these, the median age was 77.4 years with a range between 57.5 and 88.8, and 64.5% were male. Twenty-seven out of the 31 patients were able to have LF-IGRT while four had S-IGRT. There were no complications after endoscopic implantation of liquid fiducials in our cohort. The cohort overall survival (OS) post-radiotherapy was 19 mo (range 0 to 87 mo). Whilst the progression-free survival (PFS) post-radiotherapy was 13 mo (range 0 to 74 mo). For those treated with curative intent, the median OS was 22.0 mo (range 0 to 87 mo) with a PFS median of 14.0 mo (range 0 to 74 mo). Grade 3 complication rate post-radiotherapy was 29%. CONCLUSION: LF-IGRT is feasible in 87.1% of patients undergoing liquid fiducial placement through standard gastroscopy injection technique. Our cohort has an overall survival of 19 mo and PFS of 13 mo. Further studies are warranted to determine the long-term outcomes of liquid-fiducial based IGRT.

RESUMO

Upper gastrointestinal bleeding from oesophageal or gastric varices is an important medical condition in patients with portal hypertension. Despite the emergence of a number of novel endoscopic and radiologic therapies for oesophagogastric varices, controversy exists regarding the indication, timing and modality of therapy. The aim of this review is to provide a concise and practical evidence-based overview of these issues.

RESUMO

BACKGROUND AND AIM: Our aim was to evaluate the efficacy and safety of a lumen-apposing metal stent with an electrocautery-enhanced delivery system (EDS-LAMS) for endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) in regular clinical practice. METHODS: A retrospective and subsequent prospective analysis was undertaken of all patients who underwent EUS-guided drainage of their PFCs using the EDS-LAMS at 17 tertiary therapeutic endoscopy centers. RESULTS: Two hundred eight cases of EDS-LAMS deployment were attempted in 202 patients (mean age 52.9 years) at time of evaluation. Ninety-seven patients had pancreatic pseudocysts (PPs), 75 walled-off pancreatic necrosis (WOPN), 10 acute peripancreatic fluid collections (APFCs), 6 acute necrotic collections (ANCs), and 14 postoperative collections (POCs). Procedural technical success was achieved in 202/208 cases (97.1%). Maldeployment occurred in 7/208 cases (3.4%). Clinical success was achieved in 142/160 (88.8%) patients (PP 90%, WOPN 85.2%, APFC 100%, ANC 75%, POC 100%). Delayed adverse events included stent migration in 15/202 (7.4%), stent occlusion and infection in 16/202 (7.9%), major bleeding in 4/202 (2%), and buried EDS-LAMS in 2/202 (1%). PFC recurrence occurred in 13/142 (9.2%) patients; 9/202 (4.5%) required surgical or radiological intervention for PFC management after EDS-LAMS insertion. CONCLUSIONS: This large international multicenter study evaluating the EDS-LAMS for drainage of PFCs in routine clinical practice suggests that the EDS-LAMS are safe and effective for drainage of all types of PFCs; however, further endoscopic therapy is often required for WOPN. Major bleeding was a rare complication in our cohort.

RESUMO

BACKGROUND AND AIM: Telehealth has become the standard of care during the COVID-19 outbreak. This study aimed to assess doctor and patient satisfaction of endoscopy-related telehealth clinics with video consultations. METHODS: A prospective observational study of patients consecutively booked to attend two endoscopy-related telehealth clinics at an ambulatory tertiary care setting was conducted from July to October 2020. Data collected from our previously published study using phone consultations (data collected in April-May 2020) were used as a control arm. The primary outcome (satisfaction) was assessed through the six-question score (6Q_score) as per previous research. Secondary outcomes included failure-to-attend (FTA) rate and perceived necessity of physical examination/in-person follow-up appointment. RESULTS: There were 962 endoscopy clinic appointments between July and October, of which 157 were conducted through video. Data on 127 doctor questionnaires and 94 patient questionnaires were analyzed. The median age (years) of patients reviewed via video [57, interquartile range (IQR) 48-66] was lower than those reviewed via phone (65, IQR 55-74, P < 0.01). Patient average 6Q_score was higher with video compared to phone (85.1% vs 78.4%, P = 0.01), as was doctors' 6Q_score (97.5% vs 91.9%, P = 0.02). FTA rates remained similar between the two assessments (6.4% in April/May and 4.4% between July/October, P = 0.12). The requirement for in-person follow-up/physical examination was identified in two video consultations (1.6%). CONCLUSION: Video consultations during the COVID-19 outbreak demonstrated higher patient and doctor satisfaction compared to phone consultations. There was no significant difference in FTA rates and need for in-person follow-up consultations/physical examination between the telehealth two modalities.

RESUMO

BACKGROUND AND AIM: During COVID-19 outbreak, restrictions to in-person consultations were introduced with a rise in telehealth. An indirect benefit of telehealth could be better attendance. This study aimed to assess "failure-to-attend" (FTA) rate and satisfaction for two endoscopy-related compulsory telehealth clinics during the COVID-19 outbreak. METHODS: Consecutive patients booked for endoscopy-related telehealth clinics at a tertiary hospital were prospectively assessed. In-person clinic control data were assessed retrospectively. Sample size was calculated to detect an anticipated increase in attendance of 8%. Secondary outcomes included FTA differences between clinics and evaluation of patients and doctors satisfaction. Satisfaction was assessed based on six Likert scale questions used in previous telehealth research and asked to both patients and doctors (6Q_score). This study was exempt from IRB review after institutional IRB review. RESULTS: There were 691 patients booked for appointments in our endoscopy clinics during the study periods (373 in 2020). FTA rates were lowered by half during the compulsory telehealth clinics (12.6% to 6.4%, P < 0.01). The patient 6Q_score was higher for the advanced endoscopy clinic (84.6% vs 73.8%, P < 0.01), while the doctor 6Q_score was similar between both advanced clinics and post endoscopy clinics (91.1% vs 92.5% respectively, P = 0.80). An in-person follow-up consultation was suggested for 3.5% of the appointments, while the necessity of physical examination was flagged in 5.1%. CONCLUSIONS: The use of phone consultations in endoscopy-related clinics during the COVID-19 outbreak has improved FTA rates while demonstrating high satisfaction rates. The need for in-person follow-up consultations and physical examination were low.

RESUMO

BACKGROUND AND AIM: Pancreatic cancer (PC) carries a poor prognosis and is often detected at later stages. Screening programs for moderate- and high-risk people are still under debate. We present the results from a prospective study on endoscopic ultrasound (EUS) as a one-off screening tool for pancreatic cancer screening. METHODS: Asymptomatic patients with moderate- or high-risk of PC were invited to participate. Moderate risk consisted of one first-degree and at least one second-degree relative with PC and no PC-associated genetic mutations. High risk consisted of >1 first-degree relatives with PC or PC-associated mutations (i.e. BRCA2, Lynch Syndrome, Familial Atypical Multiple Mole Melanoma Syndrome, STK11, or PALB2). All included patients had genetic counseling and a screening EUS done. Primary outcome was the detection of PC on EUS. Secondary outcomes assessed the evolution of psychological symptoms based on the Impact of Events Scale (IES) and Personal Consequences Questionnaire (PCQ) before and after the screening took place. RESULTS: A total of 122 patients had a screening EUS performed between 2013 and 2019; 60 were male, 55.8 years was the mean age, 78 were at high risk for PC, and 25 had PC-associated mutations. No pancreatic cancers were identified at the one-off EUS screening. Overall, patients' IES/PCQ scores did not change after screening and feedback of no malignancy, with the exception of females (less concerned about PC after screening EUS). CONCLUSIONS: EUS did not detect any PCs in either a moderate- or high-risk population as a one-off screening method. The EUS procedure and genetic counseling improved psychological symptoms for the female subset of this population.

RESUMO

Erythropoietic protoporphyria (EPP) is an inherited metabolic disorder of heme synthesis resulting from overproduction of protoporphyrin IX (PPIX), which can lead to progressive liver disease characterized by recurrent EPP crises and end-stage liver disease. We used the Australian Transplant Registry to identify 5 patients referred for liver transplantation between 2008 and 2017. A total of 4 patients had EPP secondary to ferrochelatase deficiency, and 1 patient had X-linked EPP. No patient had follow-up with a specialist prior to the diagnosis of progressive liver disease. There were 3 patients who underwent orthotopic liver transplantation, whereas 2 died while on the transplant waiting list. Parenteral PPIX-lowering therapy was used in 4 patients and was effective in 3 patients, although 2 of these had rebound porphyria and worsening liver function following a decrease in the intensity of therapy. Early disease recurrence in the allograft following transplantation occurred in 2 patients requiring red cell exchange (RCE) to successfully attain and maintain low PPIX levels, but RCE was associated with hemosiderosis in 1 patient. Allogeneic stem cell transplantation (AlloSCT) was performed in 2 patients. One failed engraftment twice, whereas the second rejected the first graft but achieved full donor chimerism with a second graft and increased immunosuppression. In conclusion, our observations suggest that progressive liver disease needs parenteral PPIX-lowering treatment with the intensity adjusted to achieve a target Erc-PPIX level. Because EPP liver disease is universally recurrent, AlloSCT should be considered in all patients with adequate immunosuppression to facilitate engraftment. RCE appears to be effective for recurrent EPP liver disease but is associated with an increased risk of iron overload.

RESUMO

Clinicians can be forgiven for thinking of anisakiasis as a rare condition low in the differential diagnosis of abdominal pain. Gastrointestinal anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked seafood infected with nematodes of the genus Anisakis. Even though the reported cases indicate that this is a rare disease, the true incidence of the disease could be potentially higher than what is reported in the literature as cases can go undiagnosed. Diagnosis and treatment of gastric anisakiasis are made by a compatible dietary history, direct visualization, and removal of the larvae via gastroscopy. Serologic testing and imaging studies are useful in the diagnosis of intestinal anisakiasis and conservative management should be considered. This disease may mimic other diseases and lead to unnecessary surgery. This emphasizes the importance of suspecting gastrointestinal anisakiasis by history taking and by other diagnostic modalities.

RESUMO

BACKGROUND AND AIMS: Radiotherapy is an accepted modality in the treatment of esophageal cancers and is currently being evaluated in conjunction with chemotherapy for the neoadjuvant treatment of gastric cancers. Our aim was to assess whether a novel endoscopically inserted marker can be used to improve radiological assessment of the primary cancer and allow for image-guided radiotherapy. METHODS: A phase II feasibility study was conducted at a tertiary-care center. Twenty-six consecutive adult patients with esophagogastric cancers underwent endoscopic marking of the tumor margins with a novel radiopaque marker (mixture of lipiodol and n-butyl 2-cyanoacrylate). The main outcome measure was the successful insertion of the marker based on a combination of radiological, endoscopic, and histological assessment. RESULTS: A total of 92 markers were inserted in 26 patients. Twenty-two (88%) had follow-up imaging to assess the 81 markers inserted, 79 of which (97.5%) were visible. There were no postprocedural adverse events noted in our cohort. Radiological assessment of tumor size improved such that it was in line with the endoscopic evaluation after marker placement in 18 of 21 patients (85.7%) who had appropriate follow-up radiology imaging. Ten patients (38.5%) from our cohort underwent image-guided radiotherapy (IGRT) by using the endoscopically inserted markers. CONCLUSION: Within the limitations of our small pilot study, endoscopic placement of our novel marker was successful in the majority of our cohort without significant adverse events. Marker placement resulted in improved radiological localization in the majority of our cohort and allowed for IGRT. (Australian New Zealand Clinical Trials Registry: ACTRN12613000239763.).
