From Child to Old Man: A Slowly Evolving Case of Chromoblastomycosis Caused by Cladosporium cladosporioides. Antibiotics (Basel) 2023; 12:1713. [PMID: 38136747 PMCID: PMC10741158 DOI: 10.3390/antibiotics12121713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 12/01/2023] [Accepted: 12/06/2023] [Indexed: 12/24/2023] Open
Abstract
Chromoblastomycosis is a chronic granulomatous mycosis of the skin and subcutaneous tissue caused by traumatic inoculation with dematiaceous fungi. This disease primarily affects agricultural workers, who are mostly men. We present a case of chromoblastomycosis in a 63-year-old male farmer patient with dermatosis over 50 years of evolution, with warty, erythematous, and scaly plaques that predominate on the left hemithorax. Direct examination with potassium hydroxide (KOH) revealed numerous fumagoid cells. Amplification and sequencing of the internal transcribed spacer (ITS) and translation elongation factor 1-alpha (TEF-1a) gene revealed that chromoblastomycosis was caused by Cladosporium cladosporioides. The chromoblastomycosis was treated with itraconazole and fluconazole without any improvement, and amphotericin B was administered with partial improvement.

Abstract
BACKGROUND Cladosporium halotolerans is a saprobic fungus, rarely implicated in human infections. The identification is challenging due to non-specific phenotypic features. OBJECTIVE To decipher clinical spectrum, microbiological and susceptibility profile of clinical and environmental isolates of Cladosporium halotolerans. METHOD All the isolates identified as Cladosporium halotolerans deposited in National Culture Collection for Pathogenic Fungi (NCCPF), Postgraduate Institute of Medical Education and Research, Chandigarh, India were revived. Phenotypic and molecular characterization targeting internal transcribed spacer (ITS) region of ribosomal DNA, large subunit of ribosomal DNA (LSU; NL1 and NL4), actin (ACT) and beta-tubulin (TUB) was done. Scanning electron microscopy (SEM) was performed to determine any phenotypic variations. Antifungal susceptibility testing (AFST) was carried out for eight antifungal agents as per CLSI M38 Ed3 guidelines. We also performed systematic literature review of all the cases of Cladosporium halotolerans reported till date. RESULTS A total of four isolates (clinical, n = 3; soil, n = 1) identified as Cladosporium halotolerans were included in the study. The clinical sites were skin, maxillary tissue and nail. All patients were apparently immunocompetent, and history of trauma was recorded in one patient. All patients improved on antifungal therapy. The cultures revealed growth of black mycelial fungus and microscopic examination demonstrated dematiaceous septate hyphae with erect conidiophores and conidia in branched acropetal chains. Based on molecular methods, all the four isolates were identified as C. halotolerans. SEM revealed no variation in length and width of the conidia, conidiophores, ramoconidium and hyphae among the isolates. All molecular targets, such as ITS region, LSU (partially sequenced), ACT and TUB were able to differentiate the isolates. Minimum inhibitory concentrations for antifungals were: triazoles (0.12-2 μg/ml), amphotericin B (4 μg/ml) and echinocandins (2-8 μg/ml). CONCLUSION We report role of the rarely isolated dematiaceous fungus, C. halotolerans, in causing human infections. The study emphasizes the role of molecular methods in precisely identifying these species. Triazoles are more active against these black fungi compared to polyenes or echinocandins.

Abstract
Airborne fungi are ubiquitous in human living environments and may be a source of respiratory problems, allergies, and other health issues. A 12 months study was performed to investigate the diversity, concentration and community structure of culturable airborne fungi in different outdoor environments of Tianjin City, using an HAS-100B air sampler. A total of 1,015 fungal strains belonging to 175 species and 82 genera of Ascomycota 92.5%, Basidiomycota 7%, and Mucoromycota 0.3% were isolated and identified using morphological and molecular analysis. The most abundant fungal genera were Alternaria 35%, Cladosporium 18%, Penicillium 5.6%, Talaromyces 3.9%, Didymella 3%, and Aspergillus 2.8%, while the most frequently occurring species were A. alternata (24.7%), C. cladosporioides (11%), A. tenuissima (5.3%), P. oxalicum (4.53%), and T. funiculosus (2.66%). The fungal concentration ranged from 0 to 340 CFU/m3 during the whole study. Environmental factors, including temperature, relative humidity, wind speed, and air pressure exerted a varying effect on the presence and concentration of different fungal taxa. The four analyzed seasons showed significantly different airborne fungal communities, which were more strongly influenced by air temperature and relative humidity in spring and summer, whereas wind speed and air pressure had a stronger effect in autumn and winter. Fungal communities from green and busy sites did not show significant differences over the four analyzed seasons, which may be due to the effect of the surrounding environments characterized by high human activities on the air of the relatively small parks present in Tianjin. The present study provided valuable information on the seasonal dynamics and the environmental factors shaping the diversity and concentration of the analyzed outdoor airborne fungal communities, which can be of help for air quality monitoring, microbial contamination control, and health risk assessment in urban environments.

Abstract
Cladosporium species are ubiquitous dematiaceous fungi, widely found in the indoor and outdoor environments. They are considered a frequent source of contamination in laboratory settings. In human pathology, Cladosporium is a main agent of phaeohyphomycosis, known to cause subcutaneous and brain abscess, especially in immunocompromised hosts. The route of disseminated infections is mainly hematogenous after inhalation of the spores. However, a direct inoculation could be possible. We report the first case of a para-aortic abscess with thrombus formation, caused by Cladosporium spp., after a valvular replacement surgery, in an immunocompetent patient. This raises the alarm about the rapid identification of the source of contamination in the operating room, in order to prevent the emergence of further fatal infections.

Abstract
The purpose of the Brazilian Society of Anesthesiology (SBA)’s Regional Anesthesia Safety Recommendations Update is to provide new guidelines based on the current relevant clinical aspects related to safety in regional anesthesia and analgesia. The goal of the present article is to provide a broad overview of the current knowledge regarding pre-procedure asepsis and antisepsis, risk factors, diagnosis and treatment of infectious complications resulting from anesthetic techniques. It also aims to shed light on the use of reprocessed materials in regional anesthesia practice to establish the effects of aseptic handling of vials and ampoules, and to show cost-effectiveness in the preparation of solutions to be administered continuously in regional blockades. Electronic databases were searched between January 2011 (final date of the literature search for the past SBA recommendations for safety in regional anesthesia) and September 2019. A total of 712 publications were found, 201 of which were included for further analysis, and 82 new publications were added into the review. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to assess the quality of each study and to classify the strength of evidence. The present review was prepared by members of the SBA Technical Standards Committee.

Abstract
OBJECTIVES Interventional endoscopic ultrasonography (EUS) procedures are gaining popularity and the most commonly performed procedures include EUS-guided drainage of pancreatic pseudocyst, EUS-guided biliary drainage, EUS-guided pancreatic duct drainage and EUS-guided celiac plexus ablation. The aim of this paper is to formulate a set of practice guidelines addressing various aspects of the above procedures. METHODS Formulation of the guidelines was based on the best scientific evidence available. The RAND/UCLA appropriateness methodology (RAM) was used. Panellists recruited comprised experts in surgery, interventional EUS, interventional radiology and oncology from 11 countries. Between June 2014 and October 2016, the panellists met in meetings to discuss and vote on the clinical scenarios for each of the interventional EUS procedures in question. RESULTS A total of 15 statements on EUS-guided drainage of pancreatic pseudocyst, 15 statements on EUS-guided biliary drainage, 12 statements on EUS-guided pancreatic duct drainage and 14 statements on EUS-guided celiac plexus ablation were formulated. The statements addressed the indications for the procedures, technical aspects, pre- and post-procedural management, management of complications, and competency and training in the procedures. All statements except one were found to be appropriate. Randomised studies to address clinical questions in a number of aspects of the procedures are urgently required. CONCLUSIONS The current guidelines on interventional EUS procedures are the first published by an endoscopic society. These guidelines provide an in-depth review of the current evidence and standardise the management of the procedures.

Abstract
OPINION STATEMENT Pancreas cancer is a fourth-leading cause of cancer death in the USA and its incidence is rising as the population is aging. The majority of patients present at an advanced stage due to the silent nature of the disease and treatment have focused more on palliation than curative intent. Gastroenterologists have become integral in the multidisciplinary care of these patients with a focus on providing endoscopic palliation of pancreas cancer. The three most common areas that gastroenterologists palliate endoscopically are biliary obstruction, cancer-related pain, and gastric outlet obstruction. To palliate biliary obstruction, the procedure of choice is to perform endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement. We tend to place covered self-expandable metal stents (SEMS) due to their longer patency and removability unless the patient has resectable disease. Pancreas cancer pain is a result of tumor infiltration of the celiac plexus and can be severe and poorly responsive to narcotics. To improve pain control, neurolysis of the celiac plexus has been performed for decades. Since 1996, neurolysis of the celiac area has been performed endoscopically by Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis. This has proven to be as safe and effective as traditional non-endoscopic methods and has allowed the patients to decrease their narcotic use and improve their pain control. This should be done early on in the course of the disease to have maximal effect. Gastric outlet obstruction (GOO) occurs in approximately 15-20% of patients with pancreas cancer. Endoscopic palliation of GOO can be performed by placing uncovered metal enteral stents across the obstruction. This procedure has proven to be very effective in patients who have a short life expectancy (less than two to 6 months) while surgical bypass should be considered for patients with longer life expectancies because it offers better long-term symptom relief. This chapter will review the current literature, latest advancements, and optimal techniques for endoscopic palliation of pancreatic cancer.

Abstract
We assessed the diversity of culturable fungi associated with rocks of continental Antarctica to evaluate their physiological opportunistic virulence potential in vitro. The seventy fungal isolates obtained were identified as nine species of Acremonium, Byssochlamys, Cladosporium, Debaryomyces, Penicillium, and Rhodotorula. Acremonium sp., D. hansenii, P. chrysogenum, P. citrinum, P. tardochrysogenum, and R. mucilaginosa were able to grow at 37 °C; in addition, B. spectabilis displayed a high level of growth at 37 and 45 °C. Thirty-one isolates of P. chrysogenum, P. citrinum, and P. tardochrysogenum were able to produce partial haemolysis on blood agar at 37 °C. Acremonium sp., P. citrinum, and P. tardochrysogenum showed spore sizes ranging from 2.81 to 5.13 µm diameters at 37 °C. Of these, P. chrysogenum and P. tardochrysogenum displayed macro- and micro morphological polymorphism. Our results suggest that rocks of the ultra-extreme cold and dry environment of Antarctica harbour cryptic fungi phylogenetically close to opportunistic pathogenic and mycotoxigenic taxa with physiologic virulence characteristics in vitro.

Abstract
Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is widely used for reducing pain originating from upper abdominal organs. It is mainly indicated to treat pancreatic cancer pain, but also to relieve pain as a result of chronic pancreatitis. Real-time guidance and color Doppler imaging by EUS made the procedure easier and safer, resulting in greater pain relief. Currently, two techniques are used for EUS-CPN. The classic approach, known as the central technique, involves injection of a neurolytic agent at the base of the celiac axis. In the bilateral technique, the neurolytic agent is injected on both sides of the celiac axis. In addition, EUS-guided direct celiac ganglia neurolysis (EUS-CGN) was introduced recently. Pain relief is achieved by EUS-CPN in 70-80% of patients with pancreatic cancer and in 50-60% of those with chronic pancreatitis. The bilateral technique may be more efficient than the central technique, although the central technique is easier and possibly safer. Moreover, EUS-CGN may provide greater pain relief than conventional EUS-CPN. Procedure-related complications include transient pain exacerbation, transient hypotension, transient diarrhea, and inebriation. Although most complications are not serious, major adverse events such as retroperitoneal bleeding, abscess, and ischemic complications occasionally occur.

Abstract
Objectives: The objective of guideline was to provide clear and relevant consensus statements to form a practical guideline for clinicians on the indications, optimal technique, safety and efficacy of endoscopic ultrasound guided celiac plexus neurolysis (EUS-CPN). Methods: Six important clinical questions were determined regarding EUS-CPN. Following a detailed literature review, 6 statements were proposed attempting to answer those questions. A group of expert endosonographers convened in Chicago, United States (May 2016), where the statements were presented and feedback provided. Subsequently a consensus group of 35 expert endosonographers voted based on their individual level of agreement. A strong recommendation required 80% voter agreement. The modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria were used to rate the strength of recommendations and the quality of evidence. Results: Eighty percent agreement was reached on 5 of 6 consensus statements, 79.4% agreement was reached on the remaining one. Conclusions: EUS-CPN is efficacious, should be integrated into the management of pancreas cancer pain, and can be considered early at the time of diagnosis of inoperable disease. Techniques may still vary based on operator experience. Serious complications exist, but are rare.

Abstract
Endoscopic Ultrasound (EUS) provides the unique opportunity to visualize, interrogate and intervene gastrointestinal (GI) luminal, mural or peri-luminal structures and pathology with negligible adverse effects. Diagnostic, upper GI and rectal EUS is feasible, extremely safe, and efficacious. Most EUS guided interventions are safe, effective and minimally invasive, compared to peers in the percutaneous radiological or surgical procedures. As with any endoscopic procedure, EUS and its guided interventions may be accompanied by adverse events. EUS related complications are generally infrequent in expert hands, and mainly include bleeding and perforation. However, the nature and severity of adverse events associated with each EUS guided procedure are unique. Hence, it is paramount for endosonographer to have sufficient knowledge of the indications, techniques, and potential risks involved before contemplating any given procedure. Most common intervention with EUS is transmural fine needle aspiration (FNA), which is an extremely safe procedure. EUS guided drainage procedures are rapidly evolving with newer devices and methods being employed. Among them, EUS guided drainage of pancreatic fluid collection-pseudocyst or walled off necrosis (WON), has largely replaced other methods (surgical, percutaneous or non-EUS endoscopic) with acceptable complications. Currently, dedicated metal stents are more widely used compared to plastic stents for drainage of PFC, especially WON. EUS has made a definite impact in biliary access and drainage of obstructed biliary system, in patients where ERCP has failed or is technically not possible, closely competing with percutaneous biliary drainage. In spite of some complications, recent improvement in devices for bilio-enteric fistula creation and stent designs, has added to its safety and efficacy. EUS guided pancreatic duct drainage remains the most challenging of EUS guided interventions where in-roads are being made.

Abstract
There is an increasing role for endoscopic ultrasound (EUS)-guided interventions in the treatment of many conditions. Although it has been shown that these types of interventions are effective and safe, they continue to be considered only as alternative treatments in some situations. This is in part due to the occurrence of complications with these techniques, which can occur even when performed by experienced endosonographers. Although common complications have been described for many procedures, it is also crucial to be aware of uncommon complications. This review describes rare complications that have been reported with several EUS-guided interventions. EUS-guided biliary drainage is accepted as an alternative treatment for malignant biliary obstruction. Most of the uncommon complications related to this procedure involve stent malfunction, such as the migration or malposition of stents. Rare complications of EUS-guided pancreatic pseudocyst drainage can result from air embolism and infection. Finally, a range of uncommon complications has been reported for EUS-guided celiac plexus neurolysis, involving neural and vascular injuries that can be fatal. The goal of this review is to identify possible complications and promote an understanding of how they occur in order to increase general awareness of these adverse events with the hope that they can be avoided in the future.

Abstract
Cladosporium species are ubiquitous, saprobic, dematiaceous fungi, only infrequently associated with human and animal opportunistic infections. We have studied a large set of Cladosporium isolates recovered from clinical samples in the United States to ascertain the predominant species there in light of recent taxonomic changes in this genus and to determine whether some could possibly be rare potential pathogens. A total of 92 isolates were identified using phenotypic and molecular methods, which included sequence analysis of the internal transcribed spacer (ITS) region and a fragment of the large subunit (LSU) of the nuclear ribosomal DNA (rDNA), as well as fragments of the translation elongation factor 1 alpha (EF-1α) and actin (Act) genes. The most frequent species was Cladosporium halotolerans (14.8%), followed by C. tenuissimum (10.2%), C. subuliforme (5.7%), and C. pseudocladosporioides (4.5%). However, 39.8% of the isolates did not correspond to any known species and were deemed to comprise at least 17 new lineages for Cladosporium. The most frequent anatomic site of isolation was the respiratory tract (54.5%), followed by superficial (28.4%) and deep tissues and fluids (14.7%). Species of the two recently described cladosporiumlike genera Toxicocladosporium and Penidiella are reported for the first time from clinical samples. In vitro susceptibility testing of 92 isolates against nine antifungal drugs showed a variety of results but high activity overall for the azoles, echinocandins, and terbinafine.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic ultrasound - guided celiac plexus block (EUS-CPB) is an established treatment for pain in patients with chronic pancreatitis (CP), but the effectiveness and safety of repeated procedures are unknown. Our objective is to report our experience of repeated EUS-CPB procedures within a single patient. PATIENTS AND METHODS A prospectively maintained EUS database was retrospectively analyzed to identify patients who had undergone more than one EUS-CPB procedure over a 17-year period. The main outcome measures included number of EUS-CPB procedures for each patient, self-reported pain relief, duration of pain relief, and procedure-related adverse events. RESULTS A total of 248 patients underwent more than one EUS-CPB procedure and were included in our study. Patients with known or suspected CP (N = 248) underwent a mean (SD) of 3.1 (1.6) EUS-CPB procedures. In 76 % of the patients with CP, the median (range) duration of the response to the first EUS-CPB procedure was 10 (1 - 54) weeks. Lack of pain relief after the initial EUS-CPB was associated with failure of the next EUS-CPB (OR 0.17, 95 %CI 0.06 - 0.54). Older age at first EUS-CPB and pain relief after the first EUS-CPB were significantly associated with pain relief after subsequent blocks (P = 0.026 and P = 0.002, respectively). Adverse events included peri-procedural hypoxia (n = 2) and hypotension (n = 1) and post-procedural orthostasis (n = 2) and diarrhea (n = 4). No major adverse events occurred. CONCLUSIONS Repeated EUS-CPB procedures in a single patient appear to be safe. Response to the first EUS-CPB is associated with response to subsequent blocks.

Abstract
Patients with pancreatic cancer (pancreatic ductal adenocarcinoma [PDAC]) can develop abdominal pain that can be debilitating. Celiac plexus neurolysis (CPN) is a chemical ablation of the celiac plexus that can be used to treat pain caused by pancreatic malignancy. It can be performed by an anterior or posterior approach, and also can be done percutaneously or under guidance of transabdominal ultrasound, computed tomography, intra-operatively or most recently under linear endoscopic ultrasound (EUS) guidance (EUS-CPN). EUS is well-suited for identification of the celiac plexus due to the close proximity of the gastric wall to the origin of the celiac artery. EUS-CPN is now widely practiced, and different EUS approaches have been developed in order to improve the efficacy of this technique. Our objective is to review the use of EUS-CPN in PDAC, including a description of different techniques, review of its efficacy, predictors of pain response, and describe its limitations and safety, as well as new developments.

Abstract
The continued need to develop less invasive alternatives to surgical and radiologic interventions has driven the development of endoscopic ultrasound (EUS)-guided treatments. These include EUS-guided drainage of pancreatic fluid collections, EUS-guided necrosectomy, EUS-guided cholangiography and biliary drainage, EUS-guided pancreatography and pancreatic duct drainage, EUS-guided gallbladder drainage, EUS-guided drainage of abdominal and pelvic fluid collections, EUS-guided celiac plexus block and celiac plexus neurolysis, EUS-guided pancreatic cyst ablation, EUS-guided vascular interventions, EUS-guided delivery of antitumoral agents and EUS-guided fiducial placement and brachytherapy. However these procedures are technically challenging and require expertise in both EUS and interventional endoscopy, such as endoscopic retrograde cholangiopancreatography and gastrointestinal stenting. We undertook a systematic review to record the entire body of literature accumulated over the past 2 decades on EUS-guided interventions with the objective of performing a critical appraisal of published articles, based on the classification of studies according to levels of evidence, in order to assess the scientific progress made in this field.

Abstract
BACKGROUND In recent years, endoscopic ultrasonography (EUS)-guided techniques have been developed as alternatives to surgical, radiologic, or conventional endoscopic approaches for the treatment or palliation of several digestive diseases. The use of EUS guidance allows the therapeutic area to be targeting more precisely, with a possible clinical benefit and less morbidity. Nevertheless, the risks persist and must be taken into consideration. This review gives an overview of the complications observed with the most established procedures of therapeutic EUS. METHODS The PubMed and Embase databases were used to search English language articles on interventional EUS. The studies considered for inclusion were those reporting on complications of EUS-guided celiac plexus block (EUS-CPB), EUS-guided celiac plexus neurolysis (EUS-CPN), drainage of fluid pancreatic and pelvic collections, and EUS-guided biliary and pancreatic drainage (EUS-BD and EUS-PD). Variations in methodology and design in most studies made a thorough statistical analysis difficult. Instead, a frequency analysis of complications and a critical discussion were performed. RESULTS Although EUS-guided celiac plexus injection causes mainly mild and transient complications, growing experience shows that EUS-CPN is not as benign a procedure as previously thought. Most of the major complications have been observed in patients with chronic pancreatitis. The findings show that EUS-guided drainage of fluid collections is a safe procedure. Complications occur more often after the drainage of pancreatic abscesses and necrosis. Although the heterogeneity of studies dealing with pancreatobiliary drainage makes the evaluation of risks after these procedures difficult, complications after EUS-BD and EUS-PD are relatively frequent and can be severe. The technical complexity and the lack of specifically designed devices may account for their complication rates. CONCLUSIONS Clinicians can consider EUS-guided celiac injection and EUS-guided drainage of fluid collections to be safe alternatives to surgical and radiologic interventions. Well-designed prospective trials are needed to assess the risks of EUS-BD and EUS-PD accurately before they are broadly advocated after a failed endoscopic retrograde cholangiopancreatography (ERCP).

Abstract
BACKGROUND Fungal infections are rare complications of injections for treatment of chronic pain. In September 2012, we initiated an investigation into fungal infections associated with injections of preservative-free methylprednisolone acetate that was purchased from a single compounding pharmacy. METHODS Three lots of methylprednisolone acetate were recalled by the pharmacy; examination of unopened vials later revealed fungus. Notification of all persons potentially exposed to implicated methylprednisolone acetate was conducted by federal, state, and local public health officials and by staff at clinical facilities that administered the drug. We collected clinical data on standardized case-report forms, and we tested for the presence of fungi in isolates and specimens by examining cultures and performing polymerase-chain-reaction assays and histopathological and immunohistochemical testing. RESULTS By October 19, 2012, more than 99% of 13,534 potentially exposed persons had been contacted. As of July 1, 2013, there were 749 reported cases of infection in 20 states, with 61 deaths (8%). Laboratory evidence of Exserohilum rostratum was present in specimens from 153 case patients (20%). Additional data were available for 728 case patients (97%); 229 of these patients (31%) had meningitis with no other documented infection. Case patients had received a median of 1 injection (range, 1 to 6) of implicated methylprednisolone acetate. The median age of the patients was 64 years (range, 15 to 97), and the median incubation period (the number of days from the last injection to the date of the first diagnosis) was 47 days (range, 0 to 249); 40 patients (5%) had a stroke. CONCLUSIONS Analysis of data from a large, multistate outbreak of fungal infections showed substantial morbidity and mortality. The infections were associated with injection of a contaminated glucocorticoid medication from a single compounding pharmacy. Rapid public health actions included prompt recall of the implicated product, notification of exposed persons, and early outreach to clinicians.

Abstract
OBJECTIVE This systematic review assesses the effectiveness and side effects of celiac plexus neurolysis (CPN) in the treatment of upper abdominal cancer pain, and evaluates whether there are any differences between the percutaneous and endoscopic ultrasound-guided (EUS) denervation techniques. METHODS Five databases were searched, expanded by assessing the reference lists of all retrieved papers. Sixty-six publications fulfilled the inclusion/exclusion criteria and were included in the systematic review. Randomized controlled trials were available for the percutaneous CPN, and therefore meta-analyses were performed for pain, opioid consumption, and specific side effects. The quality of life data were too heterogeneous to be assessed by a meta-analysis, and evidence for EUS CPN could only be evaluated by observational studies. RESULTS Meta-analyses show that percutaneous CPN significantly improves pain in patients with upper abdominal cancer, with a decrease in opioid consumption and side effects. It is unclear whether there is any change in quality of life. Case series suggest that EUS CPN improves pain. No conclusion can be made about EUS CPN's influence on opioid consumption. Although CPN is a safe procedure, side effects and complications can occur with both the percutaneous and EUS techniques. CONCLUSIONS Following this review, evidence suggests that CPN should be considered in patients with upper abdominal cancer where the pain is not adequately controlled with systemic analgesics or when significant opioid-induced side effects are present. The percutaneous approach remains the standard technique as robust evidence for EUS CPN is lacking.
