Timing of radiotherapy (RT) after radical prostatectomy (RP): long-term outcomes in the RADICALS-RT trial (NCT00541047). Ann Oncol 2024:S0923-7534(24)00105-4. [PMID: 38583574 DOI: 10.1016/j.annonc.2024.03.010] [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: 10/20/2023] [Revised: 03/25/2024] [Accepted: 03/27/2024] [Indexed: 04/09/2024] Open
Abstract
BACKGROUND The optimal timing of radiotherapy (RT) after radical prostatectomy for prostate cancer has been uncertain. RADICALS-RT compared efficacy and safety of adjuvant RT versus an observation policy with salvage RT for prostate-specific antigen (PSA) failure. PATIENTS AND METHODS RADICALS-RT was a randomised controlled trial enrolling patients with ≥1 risk factor (pT3/4, Gleason 7-10, positive margins, preoperative PSA≥10 ng/ml) for recurrence after radical prostatectomy. Patients were randomised 1:1 to adjuvant RT ('Adjuvant-RT') or an observation policy with salvage RT for PSA failure ('Salvage-RT') defined as PSA≥0.1 ng/ml or three consecutive rises. Stratification factors were Gleason score, margin status, planned RT schedule (52.5 Gy/20 fractions or 66 Gy/33 fractions) and treatment centre. The primary outcome measure was freedom-from-distant-metastasis (FFDM), designed with 80% power to detect an improvement from 90% with Salvage-RT (control) to 95% at 10 years with Adjuvant-RT. Secondary outcome measures were biochemical progression-free survival, freedom from non-protocol hormone therapy, safety and patient-reported outcomes. Standard survival analysis methods were used; hazard ratio (HR)<1 favours Adjuvant-RT. RESULTS Between October 2007 and December 2016, 1396 participants from UK, Denmark, Canada and Ireland were randomised: 699 Salvage-RT, 697 Adjuvant-RT. Allocated groups were balanced with a median age of 65 years. Ninety-three percent (649/697) Adjuvant-RT reported RT within 6 months after randomisation; 39% (270/699) Salvage-RT reported RT during follow-up. Median follow-up was 7.8 years. With 80 distant metastasis events, 10-year FFDM was 93% for Adjuvant-RT and 90% for Salvage-RT: HR=0.68 [95% confidence interval (CI) 0.43-1.07, P=0.095]. Of 109 deaths, 17 were due to prostate cancer. Overall survival was not improved (HR=0.980, 95% CI 0.667-1.440, P=0.917). Adjuvant-RT reported worse urinary and faecal incontinence 1 year after randomisation (P=0.001); faecal incontinence remained significant after 10 years (P=0.017). CONCLUSION Long-term results from RADICALS-RT confirm adjuvant RT after radical prostatectomy increases the risk of urinary and bowel morbidity, but does not meaningfully improve disease control. An observation policy with salvage RT for PSA failure should be the current standard after radical prostatectomy. TRIAL IDENTIFICATION RADICALS, RADICALS-RT, ISRCTN40814031, NCT00541047.

Recurrence of common bile duct stones after endoscopic clearance and its predictors: A systematic review. DEN OPEN 2024; 4:e294. [PMID: 37818098 PMCID: PMC10560705 DOI: 10.1002/deo2.294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/10/2023] [Accepted: 08/25/2023] [Indexed: 10/12/2023]
Abstract
Background The primary therapeutic strategy for the management of bile duct stones (BDS) is endoscopic retrograde cholangiopancreatography. However, there may be a recurrence of BDS on follow-up. Multiple risk factors have been studied for the prediction of BDS recurrence. We aimed to analyze the incidence of symptomatic BDS recurrence, systematically review the risk factors, and analyze the most important risk factors among those. Methods A comprehensive search of three databases was conducted from inception to November 2022 for studies reporting the recurrence of BDS recurrence after endoscopic retrograde cholangiopancreatography with clearance, along with an analysis of risk factors. Results A total of 37 studies with 12,952 patients were included in the final analysis. The pooled event rate for the recurrence of BDS stones was 12.6% (95% confidence interval: 11.2-13.9). The most important risk factor was a bile duct diameter ≥15 mm, which had a significant association with recurrence in twelve studies. Other risk factors with significant association with recurrence in three or more studies were the reduced angulation of the bile duct, the presence of periampullary diverticulum, type I periampullary diverticulum, in-situ gallbladder with stones, cholecystectomy, multiple stones in the bile duct, use of mechanical lithotripsy, and bile duct stent placement. Conclusion Around one out of seven patients have BDS recurrence after the initial endoscopic retrograde cholangiopancreatography. Bile duct size and anatomy are the most important predictors of recurrence. The assessment of risk factors associated with recurrence may help keep a close follow-up in high-risk patients.

Abstract
Use of Foley catheter in patients with ileostomy, for the decompression of large bowel distal to stoma or for the administration of large bowel enema through colostomy, either to treat constipation or for bowel preparation prior to colonoscopy, is a common practice. Accidental migration of catheter during bowel irrigation through stoma can take place if it is not secured externally to the skin. We present 2 such cases with intra-colonic migration of Foley catheter that occurred during bowel irrigation and were retrieved endoscopically. To our knowledge, this is the first case report of endoscopic removal of Foley catheter that migrated internally through the stoma.

Current paradigm of endoscopic ultrasound in biliary and pancreatic duct drainage: an update. Ann Gastroenterol 2024; 37:1-14. [PMID: 38223246 PMCID: PMC10785026 DOI: 10.20524/aog.2023.0854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 10/19/2023] [Indexed: 01/16/2024] Open
Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the workhorse for biliary and pancreatic ductal interventions. Despite advances in both endoscopes and accessories for ERCP, it still has limitations in the presence of altered anatomy, luminal obstruction hindering access to the papilla, and proximal duct obstructions by tight stricture, calculi or intraductal growth. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and EUS-guided pancreatic duct drainage (EUS-PDD) have expanded the rescue procedures after failed ERCP. This review discusses the techniques and results of various EUS-BD procedures, as well as EUS-PDD.

Abstract
Gastrointestinal (GI) endoscopy is among the highest waste generator in healthcare facilities. The major reasons include production of large-volume non-renewable waste, use of single-use devices, and reprocessing or decontamination processes. Single-use endoscopic accessories have gradually replaced reusable devices over last two decades contributing to the rising impact of GI endoscopy on ecosystem. Several reports of infection outbreaks with reusable duodenoscopes raised concerns regarding the efficacy and adherence to standard disinfection protocols. Even the enhanced reprocessing techniques like double high-level disinfection have not been found to be the perfect ways for decontamination of duodenoscopes and therefore, paved the way for the development of single-use duodenoscopes. However, the use of single-use endoscopes is likely to amplify the net waste generated and carbon footprint of any endoscopy unit. Moreover, single-use devices challenge one of the major pillars of sustainability, that is, "reuse." In the era of climate change, a balanced approach is required taking into consideration patient safety as well as financial and environmental implications. The possible solutions to provide optimum care while addressing the impact on climate include selective use of disposable duodenoscopes and careful selection of accessories during a case. Other options include use of disposable endcaps and development of effective high-level disinfection techniques. The collaboration between the healthcare professionals and the manufacturers is paramount for the development of environmental friendly devices with low carbon footprint.

Abstract
ABSTRACT This review article examines the evidence-based management of colorectal cancers, focusing on topics characterized by ongoing debates and evolving evidence. To contribute to the scientific discourse, we intentionally exclude subjects with established guidelines, concentrating instead on areas where the current understanding is dynamic. Our analysis encompasses a thorough exploration of critical themes, including the evidence surrounding complete mesocolic excision and D3 lymphadenectomy in colon cancers. Additionally, we delve into the evolving landscape of perioperative chemotherapy in both colon and rectal cancers, considering its nuanced role in the context of contemporary treatment strategies. Advancements in surgical techniques are a pivotal aspect of our discussion, with an emphasis on the utilization of minimally invasive approaches such as laparoscopy and robotic surgery in both colon and rectal cancers, including advanced rectal cases. Moving beyond conventional radical procedures, we scrutinize the feasibility and implications of endoscopic resections for small tumors, explore the paradigm of organ preservation in locally advanced rectal cancers, and assess the utility of total neoadjuvant therapy in the current treatment landscape. Our final segment reviews pivotal trials that have significantly influenced the management of colorectal liver and peritoneal metastasis.

Predictors of proximal migration of straight biliary plastic stents. Indian J Gastroenterol 2023:10.1007/s12664-023-01469-y. [PMID: 38015380 DOI: 10.1007/s12664-023-01469-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 10/04/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND/AIMS Proximal biliary plastic stent migration (PSM) remains a challenging complication. The study aims at determining the PSM rate, retrieval outcomes and factors associated with PSM. METHODS Endoscopy database was analyzed from January 2016 to January 2021 to identify 1137 patients, who underwent stent removal or repeat endoscopic retrograde cholangiopancreatography (ERCP). Demography, methods of stent retrieval, outcomes and complications were noted. Logistic regression was performed to determine risk factors for PSM. Propensity score matching was done in a 1:1 manner using age, sex, comorbidities and indication to assess endoscopy-related factors. Clinical trial registration done (CTRI/2022/02/040516). RESULTS PSM was noted in 74 (6.5%) cases. Stent retrieval was successful in 94.59% (70/74) of cases. A balloon catheter (46/74) was commonly used. Technical failure was due to an impacted stent (2) and stent above the stricture (2). Complications were seen in 2.7% of cases. On multi-variate regression, sphincteroplasty at index ERCP (Odds ratio [OR] = 5.68, 95% confidence interval [CI] = 2.7-11.89), stent length < 10 cm (OR = 8.53, 95% CI = 3.2-22.47), 7-Fr stent (OR = 18.25, 95% CI = 6.5-50.64), dilated bile duct (mean diameter- 9.2 ± 3.94 mm) (OR = 0.384, 95% CI = 0.18-0.72) and delayed ERCP by > 3 months from index ERCP (OR = 15.28, 95% CI = 8.1-28.49). After performing propensity score matching for age, sex, comorbidities and indication to determine endoscopy-related factors, 7-Fr stent size (OR 3.495; 95% CI-1.23-9.93) and duration of indwelling stent for more than three months (OR-3.37; 95% CI-1.646-6.76) were significantly associated with proximal stent migration. CONCLUSION Proximally migrated straight stents can be successfully retrieved using standard accessories. The use of 7-Fr size stent, stents indwelling for more than three months, sphincteroplasty at index ERCP, stent length < 10 cm and dilated bile duct were associated with increased risk of proximal migration of straight biliary plastic stents. After propensity score matching, the use of 7-Fr size stents and stent indwelling for over three months were endoscopy-related factors associated with proximal migration.

Role of endoscopic ultrasound-guided tissue acquisition for the diagnosis of gastric wall thickening: a retrospective study with meta-analysis. Ann Gastroenterol 2023; 36:605-614. [PMID: 38023968 PMCID: PMC10662068 DOI: 10.20524/aog.2023.0831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 10/03/2023] [Indexed: 12/01/2023] Open
Abstract
Background Tissue acquisition from a thickened gastric wall using biopsy forceps may not always lead to diagnosis, given the submucosal location of the pathology. Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) may serve as a minimally invasive diagnostic tool in such cases. Hence, we aimed to assess the diagnostic outcome and safety of EUS-TA from thickened gastric walls. Methods Data from patients with gastric wall thickening undergoing EUS-TA at 5 tertiary care centers from August 2020 to August 2022 were retrospectively analyzed. These data were pooled with studies obtained from a comprehensive search of Medline, Embase and Scopus from January 2000 to November 2022 and a meta-analysis was performed. Pooled event rates were calculated using an inverse variance model. Results The search strategy yielded 13 studies that were combined with data from 30 patients from our centers; a total of 399 patients were included in the analysis. The pooled rate of sample adequacy was 94.1% (95% confidence interval [CI] 90.0-98.2), while the pooled rate of diagnostic accuracy was 91.3% (95%CI 87.0-95.5). The pooled sensitivity and specificity for diagnosing malignant lesions with EUS-TA from gastric wall thickening were 94.8% (95%CI 91.3-97.2) and 100% (95%CI 93.6-100), respectively. There were no reported adverse events in any of the studies. Conclusions EUS-TA offers a safe and accurate diagnostic modality for the etiological diagnosis of thickened gastric walls. Further research is required to identify the needle type and optimal technique for improving outcomes.

Abstract
INTRODUCTION IgG4-related disease (IgG4-RD) is a rare disease entity in India. We aimed at studying the clinical profile of IgG4-RD of gastrointestinal tract (GIT) from our centre, while systematically reviewing data from India. METHODS Retrospective review of IgG4-RD of GIT was done using electronic medical records between January 2013 and July 2022. Literature search was done for studies of IgG4-RD of the GIT reported from India from 2000 till January 2023. Case series, case reports of IgG4-RD of GIT and case reports describing GIT with multi-organ involvement were included in the review. Primary outcome measure was response to treatment. Secondary outcome measure was relapse after remission. RESULTS Thirty-one patients were included with 71% (22/31) having autoimmune pancreatitis. The diagnosis was achieved on surgical specimen in 35% (11/31) patients. Steroid was given to 64% (20/31) patients with remission achieved in 70% (14/20) patients. Four patients exhibitted response to prolonged course of steroids with maintenance azathioprine. Relapse was seen in four (20%) patients who achieved remission. Of 731 articles screened, 48 studies (four case series and 44 case reports) were included in the literature review. Of 95 patients described, steroids were given to 65.2% (62/95), while surgery was done in 33.6% (32/95). Remission was seen in 96.6% (85/88) with relapse occurring in 11.4% (10/88) patients on follow-up. CONCLUSION One-third patients of IgG4-RD of GIT are diagnosed after surgery. Response to steroids is good with relapse occurring in up to 12% patients.

Abstract
BACKGROUND Both Budd-Chiari syndrome (BCS) and portal vein thrombosis (PVT) have been linked to various prothrombotic (PT) conditions. The PT profile in Asians is different from the west and there are no nationwide epidemiological surveys from India. Hence, the present meta-analysis was aimed at analyzing the prevalence of acquired and hereditary thrombophilia among Indian patients with non-cirrhotic PVT and BCS. METHODS A comprehensive literature search of Embase, Medline and Scopus was conducted from January 2000 to February 2022 for studies evaluating the prevalence of various PT conditions in Indian patients with PVT and BCS. Pooled prevalence rates across studies were expressed with summative statistics. RESULTS Thirty-five studies with 1005 PVT patients and 1391 BCS patients were included in the meta-analysis. At least one PT condition was seen in 46.2% (28.7-63.7) of the PVT patients and 44.9% (37.3-60.7) of the BCS patients. Multiple PT conditions were seen in 13.0% (4.2-21.8) of the PVT patients and 7.9% (3.5-12.4) of the BCS patients. Among PVT patients, hyperhomocysteinemia was the commonest prothrombotic condition (21.6%) followed by protein C (PC) deficiency (10.7%), Janus kinase 2 (JAK-2) mutation (8.5%) and antiphospholipid antibodies (APLA) (7.5%). Among patients with BCS, PC deficiency was the commonest prothrombotic condition (10.6%) followed by methylenetetrahydrofolate reductase (MTHFR) mutation (9.8%), APLA (9.7%) and JAK-2 mutation (9.1%). CONCLUSION The PT profile in Indian patients with abdominal vein thrombosis is different from that of the western data with a lower prevalence of PT conditions in patients with BCS.

Abstract
BACKGROUND AND AIMS Multiple meta-analyses have evaluated the technical and clinical success of EUS-guided biliary drainage (BD), but meta-analyses concerning adverse events (AEs) are limited. The present meta-analysis analyzed AEs associated with various types of EUS-BD. METHODS A literature search of MEDLINE, Embase, and Scopus was conducted from 2005 to September 2022 for studies analyzing the outcome of EUS-BD. The primary outcomes were incidence of overall AEs, major AEs, procedure-related mortality, and reintervention. The event rates were pooled using a random-effects model. RESULTS One hundred fifty-five studies (7887 patients) were included in the final analysis. The pooled clinical success rates and incidence of AEs with EUS-BD were 95% (95% confidence interval [CI], 94.1-95.9) and 13.7% (95% CI, 12.3-15.0), respectively. Among early AEs, bile leak was the most common followed by cholangitis with pooled incidences of 2.2% (95% CI, 1.8-2.7) and 1.0% (95% CI, .8-1.3), respectively. The pooled incidences of major AEs and procedure-related mortality with EUS-BD were .6% (95% CI, .3-.9) and .1% (95% CI, .0-.4), respectively. The pooled incidences of delayed migration and stent occlusion were 1.7% (95% CI, 1.1-2.3) and 11.0% (95% CI, 9.3-12.8), respectively. The pooled event rate for reintervention (for stent migration or occlusion) after EUS-BD was 16.2% (95% CI, 14.0-18.3; I2 = 77.5%). CONCLUSIONS Despite a high clinical success rate, EUS-BD may be associated with AEs in one-seventh of the cases. However, major AEs and mortality incidence remain less than 1%, which is reassuring.

Abstract
BACKGROUND Insulinoma is the most common functional pancreatic neuroendocrine tumor and treatment is required to address symptoms associated with insulin hypersecretion. Surgical resection is effective but burdened by high rate of adverse events (AEs). Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) demonstrated encouraging results in terms of safety and efficacy for the management of these tumors. However, studies comparing surgery and EUS-RFA are lacking. AIMS The primary aim is to compare EUS-RFA with surgery in term of safety (overall rate of AEs). Secondary endpoints include: (a) severe AEs rate; (b) clinical effectiveness; (c) patient's quality of life; (d) length of hospital stay; (e) rate of local/distance recurrence; (f) need of reintervention; (g) rate of endocrine and exocrine pancreatic insufficiency; (h) factors associated with EUS-RFA related AEs and clinical effectiveness. METHODS ERASIN-RCT is an international randomized superiority ongoing trial in four countries. Sixty patients will be randomized in two arms (EUS-RFA vs surgery) and outcomes compared. Two EUS-RFA sessions will be allowed to achieve symptoms resolution. Randomization and data collection will be performed online. DISCUSSION This study will ascertain if EUS-RFA can become the first-line therapy for management of small, sporadic, pancreatic insulinoma and be included in a step-up approach in case of clinical failure.

Abstract
Background Concerned studies with respect to the outcome of pregnant patients with non-cirrhotic portal hypertension are limited. Thus, a systematic review and meta-analysis of the available literature was conducted. Methods A literature search was conducted from 1999 to December 2021 for studies evaluating pregnancy outcomes in patients with non-cirrhotic portal hypertension. Results Twelve studies were included in the meta-analysis. The pooled rate of variceal bleeding, ascites and severe anemia requiring blood transfusion were 9.6%, 2.3%, and 14.9%, respectively. The pooled rate of spontaneous miscarriage, gestational hypertension, delivery by cesarean section, and postpartum hemorrhage were 11.9%, 4.5%, 36.7%, and 4.7%, respectively. The pooled stillbirth rate was 2.5% and among the live births, the pooled rates of preterm birth, low birth weight, intensive care unit admission, and neonatal mortality were 21.6%, 18.7%, 15.5%, and 1.8%, respectively. Conclusion Pregnancy in patients with non-cirrhotic portal hypertension is associated with increased maternal & fetal morbidity but mortality remains low.

Abstract
Background Lumen-apposing metal stents (LAMS) are an evolving option for the management of benign gastrointestinal (GI) strictures. Multiple studies have reported on the efficacy and safety of LAMS for benign GI strictures, but were limited by their small sample size. Hence, we conducted this meta-analysis to assess the critical role of LAMS for the management of benign GI strictures. Methods A literature search of various databases from inception until October 2022 was conducted for studies evaluating the outcome of LAMS in patients with benign GI strictures. The outcomes assessed included technical and clinical success, adverse events including stent migration, and reintervention. Pooled event rates across studies were expressed with summative statistics. Results A total of 18 studies (527 patients) were included in the present analysis. The pooled event rates for technical, short-term and long-term clinical success were 99.9% (95% confidence interval [CI] 99.1-100.0), 93.9% (95%CI 90.7-100.0), and 72.8% (95%CI 55.7-90.0), respectively. The pooled incidence of adverse events and stent migration with LAMS for benign GI strictures was 13.5% (95%CI 8.6-18.5) and 10.6% (95%CI 6.0-15.2), respectively. The pooled event rate for reintervention with LAMS for GI strictures was 23.0% (95%CI 15.7-30.3). In a subgroup analysis focusing only on anastomotic strictures there was no significant difference in the pooled event rates for various outcomes. Conclusions LAMS have a high technical and short-term clinical success rate, with an acceptable safety profile for the management of benign GI strictures. Further studies are needed to determine the appropriate duration of stent therapy and long-term outcomes.

Diagnostic efficacy of endoscopic ultrasound-guided liver biopsy for diffuse liver diseases and its predictors - a multicentric retrospective analysis. Clin Exp Hepatol 2023; 9:243-250. [PMID: 37790688 PMCID: PMC10544065 DOI: 10.5114/ceh.2023.130618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Accepted: 06/07/2023] [Indexed: 10/05/2023] Open
Abstract
Aim of the study Endoscopic ultrasound (EUS)-guided liver biopsy (LB) has become an increasingly popular method of tissue acquisition for evaluating liver diseases. Despite its advantages, EUS-LB has not been widely adopted in clinical practice due to concerns regarding efficacy and safety. Present data on EUS-LB from India are scarce. We aimed to study the diagnostic outcome and safety of EUS-guided liver biopsy. Material and methods This is a retrospective analysis of prospectively maintained data from January 2021 to October 2022 of consecutive patients undergoing EUS-LB at four tertiary care centers in India. The primary outcome was sample adequacy, while secondary outcomes were rate of successful pathological diagnoses and incidence of adverse events (AE). Results A total of 74 patients (median age: 44.5 years, 50.0% males) were included. The majority of the patients underwent left-lobe biopsy (62/74, 83.7%), and a 19-G Franseen FNB needle was most commonly used (61/74, 82.4%). Wet heparin suction was used in most cases (60/74, 81.1%). There were five mild AEs observed (one case of self-limited bleeding and four cases of post-procedural pain). Adequate and optimal samples were obtained in 71 (95.9%) and 49 (66.2%) cases, with a conclusive diagnosis being made in 97.3% (72/74) of the patients. On multivariate analysis, the presence of ascites was a negative predictor of optimal sample (odds ratio [OR] = 0.128, 95% CI: 0.017-0.96). Conclusions EUS-LB is a safe and viable alternative to percutaneous liver biopsy, achieving diagnosis in > 95% of cases. EUS-LB can be performed safely even in patients with mild ascites, although ascites reduces the chances of getting an optimal sample.

Atezolizumab plus bevacizumab versus lenvatinib as first-line therapy for advanced hepatocellular carcinoma: A systematic review and meta-analysis. Clin Exp Hepatol 2023; 9:228-235. [PMID: 37790692 PMCID: PMC10544063 DOI: 10.5114/ceh.2023.130748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 05/16/2023] [Indexed: 10/05/2023] Open
Abstract
Aim of the study Studies comparing atezolizumab plus bevacizumab (ATE/BEV) vs. lenvatinib (LEN) for advanced hepatocellular carcinoma (aHCC) have shown conflicting results. With this background, we aimed to collate the available evidence comparing ATE/BEV and LEN in aHCC. Material and methods A comprehensive search of three databases was conducted from inception to November 2022 for studies comparing ATE/BEV with LEN for managing aHCC. Results were presented with their 95% confidence intervals (95% CI) as the hazard ratio (HR) for time-to-event outcomes or odds ratios (OR) for dichotomous outcomes. Results A total of 8 studies were included. On analysis of matched cohorts, there was no difference in the objective response rate (ORR) (adjusted odds ratio [aOR] = 1.15, 95% CI: 0.83-1.61) or disease control rate (DCR) (aOR = 0.83, 95% CI: 0.49-1.38) between groups. Three studies reported a significantly longer progression-free survival (PFS) with ATE/LEN, while one reported a longer PFS with LEN. The adjusted hazard ratio (aHR) for PFS available from three studies was comparable (HR = 1.06, 95% CI: 0.75-1.50). Data were insufficient to carry out a formal analysis for overall survival (OS), but none of the studies reported any difference in OS. On comparison of overall adverse events (AE) and ≥ grade 3 AE, there was no difference in the overall analysis, but higher risk of AE with LEN on sensitivity analysis. Conclusions Based on the currently available literature, LEN was found to be non-inferior to ATE/BEV in terms of ORR, DCR, and PFS. However, LEN may be associated with a higher incidence of AEs. Further head-to-head trials are required to demonstrate the superiority of ATE/BEV over LEN.

Endoscopic Ultrasound-guided Versus Percutaneous Transhepatic Biliary Drainage After Failed ERCP: A Systematic Review and Meta-analysis. Surg Laparosc Endosc Percutan Tech 2023; 33:411-419. [PMID: 37314182 DOI: 10.1097/sle.0000000000001192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 05/02/2023] [Indexed: 06/15/2023]
Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) may fail to achieve biliary drainage in 5% to 10% of cases. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and percutaneous transhepatic biliary drainage (PTBD) are alternative therapeutic options in such cases. The present meta-analysis aimed to compare the efficacy and safety of EUS-BD and PTBD for biliary decompression after failed ERCP. METHODS A comprehensive search of literature from inception to September 2022 was done of 3 databases for studies comparing EUS-BD and PTBD for biliary drainage after failed ERCP. Odds ratios (ORs) with 95% CIs were calculated for all the dichotomous outcomes. Continuous variables were analyzed using mean difference (MD). RESULTS A total of 24 studies were included in the final analysis. Technical success was comparable between EUS-BD and PTBD (OR=1.12, 0.67-1.88). EUS-BD was associated with a higher clinical success rate (OR=2.55, 1.63-4.56) and lower odds of adverse events (OR=0.41, 0.29-0.59) compared with PTBD. The incidence of major adverse events (OR=0.66, 0.31-1.42) and procedure-related mortality (OR=0.43, 0.17-1.11) were similar between the groups. EUS-BD was associated with lower odds of reintervention with an OR of 0.20 (0.10-0.38). The duration of hospitalization (MD: -4.89, -7.73 to -2.05) and total treatment cost (MD: -1355.46, -2029.75 to -681.17) were significantly lower with EUS-BD. CONCLUSIONS EUS-BD may be preferred over PTBD in patients with biliary obstruction after failed ERCP where appropriate expertise is available. Further trials are required to validate the findings of the study.

Abstract
Background and study aims Despite the widespread use of endoscopic ultrasound (EUS)-guided tissue acquisition, the choice of optimal suction technique remains a subject of debate. Multiple studies have shown conflicting results with respect to the four suction techniques: Dry suction (DS), no suction (NS), stylet slow-pull (SSP) and wet suction (WS). Thus, the present network meta-analysis (NMA) was conducted to compare the diagnostic yields of above suction techniques during EUS-guided tissue acquisition. Methods A comprehensive literature search from 2010 to March 2022 was done for randomized trials comparing the aspirated sample and diagnostic outcome with various suction techniques. Both pairwise and network meta-analyses were performed to analyze the outcomes: sample adequacy, moderate to high cellularity, gross bloodiness and diagnostic accuracy. Results A total of 16 studies (n=2048 patients) were included in the final NMA. WS was associated with a lower odd of gross bloodiness compared to DS (odds ratio 0.50, 95% confidence interval 0.24-0.97). There was no significant difference between the various suction methods with respect to sample adequacy, moderate to high cellularity and diagnostic accuracy. On meta-regression, to adjust for the effect of needle type, WS was comparable to DS in terms of bloodiness when adjusted for fine-needle aspiration needle. Surface under the cumulative ranking analysis ranked WS as the best modality for all the outcomes. Conclusions The present NMA did not show superiority of any specific suction technique for EUS-guided tissue sampling with regard to sample quality or diagnostic accuracy, with low confidence in estimates.

Abstract
BACKGROUND Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) is widely used for various target samples, but its efficacy in gallbladder (GB) lesions is unknown. The aim of the present meta-analysis was to assess the pooled adequacy, accuracy and safety of EUS-TA of GB lesions. METHODS A literature search from January 2000 to August 2022 was done for studies analyzing the outcome of EUS-guided TA in patients with GB lesions. Pooled event rates were expressed with summative statistics. RESULTS The pooled rate of sample adequacy for all GB lesions and malignant GB lesions was 97.0% (95% CI: 94.5-99.4) and 96.6% (95% CI: 93.8-99.3), respectively. The pooled sensitivity and specificity for the diagnosis of malignant lesions were 90% (95% CI: 85-94; I2 = 0.0%) and 100% (95% CI: 86-100; I2 = 0.0%), respectively, with an area under the curve of 0.915. EUS-guided TA had a pooled diagnostic accuracy rate of 94.6% (95% CI: 90.5-96.6) for all GB lesions and 94.1% (95% CI: 91.0-97.2) for malignant GB lesions. There were six reported mild adverse events (acute cholecystitis = 1, self-limited bleeding = 2, self-limited episode of pain = 3) with a pooled incidence of 1.8% (95% CI: 0.0-3.8) and none of the patients had serious adverse events. CONCLUSION EUS-guided tissue acquisition from GB lesions is a safe technique with high sample adequacy and diagnostic accuracy. EUS-TA can be an alternative when traditional sampling techniques fail or are not feasible.

Abstract
INTRODUCTION Electrosurgical unit (ESU) is integral to the endoscopy unit. The proper knowledge of the Mode with setting is essential for good therapeutic outcomes and the safety of the patients. AREAS COVERED ESU generates high-frequency electric current, which could perform cutting and coagulation for various therapeutic interventions. We review the proper settings for common endoscopic interventions like hemostasis, polypectomy, sphincterotomy, and advanced procedures like endoscopic ultrasound-guided cysto-gastrostomy, bile duct drainage, and endoscopic Ampullectomy. We review the various waveforms of ESU in practice in endoscopy, including special conditions like patients with pacemakers. EXPERT OPINION Knowledge of the waveforms' duty cycle and crest factor is necessary. A high-duty cycle and lower crest factor lead to a good cutting effect on the tissue. Endocut is the most commonly used Mode in ESU in endoscopic practices like sphincterotomy and polypectomy. Endocut I mode (effect 1-2, duration 3, interval 3) is used for endoscopic sphincterotomy, while Forced Coag mode (Effect 2, 60 W) controls post-sphincterotomy bleeding. Endocut Q mode (Effect 2-3, duration 1, interval 3) is used for cutting the polyp, while Forced Coag mode (Effect 2, 60 W) is used before cutting for pre-coagulation of the stalk.

Abstract
INTRODUCTION Placement of biliary self-expanding metal stents (SEMS) has been effective for palliation of unresectable hilar malignant biliary obstruction. Optimal drainage in hilar obstruction may require placement of multiple stents. Data on multiple SEMS placement in hilar obstruction from India is sparse. METHODS Retrospective review of patients with unresectable malignant hilar obstruction who underwent endoscopic bilateral SEMS insertion from 2017 to 2021 was done. Demographic details, technical success and functional success (decrease in the bilirubin value below 3 mg/dL at four weeks), immediate complications with 30-days mortality, requirement of re-intervention, stent patency and overall survival were studied. RESULTS Forty-three patients were included (mean age 54.9 years, 51.2% females). Thirty-six patients (83.7%) had carcinoma gallbladder as primary malignancy. Twenty-six patients (60.5%) were metastatic at presentation. Cholangitis was seen in 4/43 (9.3%). On cholangiogram, 26 (60.4%) had Bismuth type II block, 12 (27.8%) had type IIIA/B, 5 (11.6%) had type IV block. Technical success was achieved in 41/43 (95.3%) patients (38, side-by-side SEMS placement; 3, SEMS-within-SEMS in Y fashion). Functional success was achieved in 39 patients (95.1%). No moderate-severe complications were reported. Median post-procedure hospitalization was five days. Median stent patency was 137 days (interquartile range [IQR] 80-214 days). Re-intervention was required in four patients (9.3%) after mean 295.7 days. Median overall survival was 153 days (IQR 108-234 days). CONCLUSION Endoscopic bilateral SEMS in complex malignant hilar obstruction has good outcomes in the form of technical success, functional success and stent patency. Survival is dismal despite optimal biliary drainage.

Abstract
Chronic pancreatitis (CP) is a known risk factor for pancreatic cancer. CP may present with an inflammatory mass, and differentiation from pancreatic cancer is often difficult. Clinical suspicion of malignancy dictates a need for further evaluation for underlying pancreatic cancer. Imaging modalities remain the mainstay of evaluation for a mass in background CP; however, they have their shortcomings. Endoscopic ultrasound (EUS) has become the go-to investigation. Adjunct modalities such as contrast-harmonic EUS and EUS elastography, as well as EUS-guided sampling using newer-generation needles are useful in differentiating inflammatory from malignant masses in the pancreas. Paraduodenal pancreatitis and autoimmune pancreatitis often masquerade as pancreatic cancer. In this narrative review, we discuss the various modalities used to differentiate inflammatory from malignant masses of the pancreas.

Efficacy and safety of endosonography-guided transvascular needle aspiration of thoracic and abdominal lesions: A systematic review and meta-analysis. JOURNAL OF CLINICAL ULTRASOUND : JCU 2023; 51:723-730. [PMID: 36787224 DOI: 10.1002/jcu.23441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 01/29/2023] [Accepted: 01/31/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND The diagnosis of intrathoracic and abdominal masses is challenging when lesions are located behind major vessels. Endoscopic ultrasound (EUS) or endobronchial ultrasound (EBUS)-guided transvascular needle aspiration (TVNA) provides a potentially useful diagnostic tool for such lesions. Data with respect to the safety and outcome of E-TVNA are scarce. Hence, this meta-analysis was conducted to assess the critical role of E-TVNA for diagnosis of various lesions. METHODS AND MATERIAL A meta-analysis was performed by pooling the data from studies obtained from comprehensive search of Medline, Embase, and Scopus from January 2000 to September 2022. The outcomes analyzed included sample adequacy, diagnostic accuracy and adverse events including bleeding. RESULTS A total of 17 studies (n = 411) were included in the final analysis. The pooled rate of sample adequacy was 91.5% [95% confidence interval (CI): 86.8-96.2], while the pooled rate of diagnostic accuracy was 85.0% (95% CI: 78.9-91.2). The pooled rate of bleeding with E-TVNA was 1.4% (95% CI 0.0-3.1%). All the episodes of bleeding were mild and resolved without any further intervention. There was no significant heterogeneity with respect to various outcomes and results were comparable on sensitivity analysis. CONCLUSIONS E-TVNA offers a safe and accurate diagnostic modality for the diagnosis of mediastinal and abdominal lesions located on the other side of major vessels. Selection of potential candidates and close periprocedural observation are essential to improve the outcome.

Abstract
Background Rapid on-site examination (ROSE) during endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) has been a subject of debate. We compared the yield of EUS-FNB with adequacy assessed using macroscopic on-site evaluation (MOSE), and smear cytology with adequacy confirmed by ROSE, acquired using the same needle. Methods Consecutive patients with solid pancreatic lesions (SPLs) who underwent EUS-FNB of pancreatic solid lesions between January 2021 and July 2022 were included. Demographic details, site and size of lesion, number of passes, and the diagnosis by cytology and histopathology of core tissue were noted. The first pass was used for ROSE adequacy assessment and was subsequently sent for cytological assessment. Additional passes were taken subsequently to acquire core tissue. Adequacy was confirmed by MOSE (whitish core of more than 4 mm). Final cytology and histopathology (HPE) were compared for diagnostic accuracy. Results One hundred fifty-five patients were included in the analysis during the study period (mean age 55.1+12.9 years; 60% male; 77% in pancreatic head; median size 3.7 cm). The final diagnosis was malignancy in 129, while 26 were negative for malignancy. Sensitivity and specificity for ROSE with cytology in detecting malignant SPLs were 96.9% and 100%, respectively. HPE with MOSE had sensitivity and specificity of 96.1% and 100%, respectively. A comparison of diagnostic accuracy showed no significant difference (P>0.99) between HPE with MOSE and ROSE with cytology, using an FNB needle. Conclusion MOSE is as good as ROSE in terms of diagnostic yield for solid pancreatic lesions sampled using newer-generation EUS biopsy needles.

Abstract
BACKGROUND underwater endoscopic mucosal resection (uEMR) without submucosal injection for sessile colorectal polyps was introduced as a new replacement for conventional EMR (cEMR). However, the optimal resection strategy remains a topic of debate. Hence, this meta-analysis was performed to compare the efficacy and safety of uEMR and cEMR in patients with sessile colorectal polyps. METHODS a comprehensive search of the literature from 2000 till January 2022 was performed from Medline, CENTRAL and Embase for randomized controlled trials (RCTs) comparing cEMR vs uEMR for colorectal polyps. The evaluated outcomes included en bloc resection, R0 resection, procedure time, overall bleeding and recurrence. Pooled risk ratios (RR) with 95 % confidence interval were calculated using a random effect model. RESULTS six studies were included, out of which four were full-text articles and two were conference abstracts. En bloc resection (RR 1.26, 95 % CI: 1.00-1.60), R0 resection (RR 1.10, 95 % CI: 0.96-1.26), overall bleeding (RR 0.85, 95 % CI: 0.54-1.34) and recurrence rate (RR 0.75, 95 % CI: 0.45-1.27) were comparable between uEMR and cEMR. However, uEMR was associated with a shorter procedure time (mean difference [MD] -1.55 minutes, 95 % CI: -2.71 to -0.39). According to the subgroup analysis, uEMR led to a higher rate of en bloc resection (RR 1.41, 95 % CI: 1.07-1.86) and R0 resection (RR 1.19, 95 % CI: 1.01-1.41) for polyps ≥ 10 mm in size. CONCLUSION both uEMR and cEMR have a comparable safety and efficacy. For polyps larger than 10 mm, uEMR may have an advantage over cEMR and should be the topic for future studies.

Abstract
SETTING The BUDS (not an acronym) institutions comprise a community-based rehabilitation initiative for children and families affected by developmental disabilities in Kerala, India. OBJECTIVE To explore the role of local governments in the establishment and functioning of BUDS institutions. DESIGN We used qualitative approaches comprising document review and in-depth interviews with trainers, parents of children with developmental disabilities and elected representatives. RESULTS BUDS was created by Kudumbasree, a decentralised women empowerment and poverty alleviation initiative. Our findings illustrate the role of local governments in facilitating expansion through the establishment of infrastructure, therapy equipment, transportation and financial allocation for these, as well as through the development of human resources, assistance with enrolment for financial assistance and insurance programmes, and coordination with education and health sectors. Programme implementation varied considerably regarding available infrastructure, staffing and services among the institutions studied. The institutions were physically closed during the COVID-19 pandemic but continued to function in alternative ways. CONCLUSION Despite variable implementation, local governments have supported the expansion of BUDS institutions, thereby creating more spaces for inclusive and integrated education and rehabilitation of persons with disabilities in Kerala. The expansion over the past two decades and measures during the COVID-19 pandemic suggest resilience and sustainability of the model.

Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred modality for drainage of the obstructed biliary tree. In patients with surgically altered anatomy, ERCP using standard techniques may not be feasible. Enteroscope assisted ERCP is usually employed with variable success rate. With advent of endoscopic ultrasound (EUS), biliary drainage procedures in patients with biliary obstruction and surgically altered anatomy is safe and effective. In this narrative review, we discuss role of EUS guided biliary drainage in patients with altered anatomy and the various approaches used in patients with benign and malignant biliary obstruction.

Transesophageal endoscopic ultrasound-guided tissue acquisition of lung masses: a case series with systematic review and meta-analysis. Ann Gastroenterol 2023; 36:185-194. [PMID: 36864937 PMCID: PMC9932857 DOI: 10.20524/aog.2023.0778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Accepted: 01/02/2023] [Indexed: 02/05/2023] Open
Abstract
Background The diagnosis of intraparenchymal lung masses is challenging when lesions are located at sites inaccessible through bronchoscopy or endobronchial ultrasound. Endoscopic ultrasound (EUS)-guided tissue acquisition (TA)-fine-needle aspiration (FNA) or fine-needle biopsy-provides a potentially useful diagnostic tool for lesions located adjacent to the esophagus. This study was conducted to analyze the diagnostic outcome and safety of EUS-guided tissue sampling of lung masses. Methods Data were retrieved for patients who underwent transesophageal EUS-guided TA between May 2020 and July 2022 at 2 tertiary care centers. A meta-analysis was performed after pooling these data with studies obtained from a comprehensive search of Medline, Embase, and ScienceDirect from January 2000 to May 2022. Pooled event rates across studies were expressed with summative statistics. Results After screening, 19 studies were identified and, after their data had been combined with those of 14 patients from our centers, a total of 640 patients were included in the analysis. The pooled rate of sample adequacy was 95.4% (95% confidence interval [CI] 93.1-97.8), while the pooled rate of diagnostic accuracy was 93.4% (95%CI 90.7-96.1). The pooled rate of adverse events with transesophageal EUS-guided TA from lung masses was 0.7% (95%CI 0.0-1.6%). There was no significant heterogeneity with respect to various outcomes and results were comparable on sensitivity analysis. Conclusions EUS-FNA offers a safe and accurate diagnostic modality for the diagnosis of paraesophageal lung masses. Future studies are needed to determine the needle type and techniques for improving outcomes.

Comparison of efficacy and safety of endoscopic and radiological interventions for gastric varices: A systematic review and network meta-analysis. Clin Exp Hepatol 2023; 9:57-70. [PMID: 37064836 PMCID: PMC10090989 DOI: 10.5114/ceh.2023.126077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Accepted: 01/14/2023] [Indexed: 04/18/2023] Open
Abstract
Aim of the study There is a paradigm shift in the management of gastric varices with the availability of endoscopic ultrasound and radiologic interventions. The optimal choice of intervention remains a dilemma for most treating physicians. Material and methods We searched MEDLINE, the Cochrane Central Register of Controlled Trials, and ScienceDirect for studies comparing endoscopic glue injection, endoscopic thrombin injection (THB), variceal band ligation, EUS-guided coiling, EUS-guided glue injection, EUS-guided coiling with glue (EUS-C+G), balloon occluded retrograde transvenous obliteration (BRTO), and transjugular intrahepatic portosystemic shunt (TIPS) for gastric varices in adults. The data on four outcomes - obliteration of varices, rebleeding, adverse effects, and mortality - were pooled using a random-effects model. Treatment estimates were calculated as odds ratios (ORs) along with their 95% confidence interval (CI). The relative ranking of interventions for various outcomes was calculated as their surface under the cumulative ranking curve (SUCRA). Results We identified 34 studies (10 randomized controlled trials, 24 non-randomized trials) with 2783 patients. Based on SUCRA plots, BRTO (SUCRA 95.1) had the highest rate of variceal obliteration followed by EUS-C+G (SUCRA 80.9). The risk of rebleeding was lowest with BRTO (SUCRA 85.1) followed by EUS-C+G (SUCRA 78.8). Moderate-severe adverse effects were least likely with THB (SUCRA 92.5) and highest with TIPS (SUCRA 3.7). In terms of mortality, EUS-C+G (73.5) had the lowest probability of overall mortality followed by TIPS (69.1). Conclusions In this network meta-analysis, we found BRTO and EUS-guided therapies to be superior to endoscopic glue injection. However, the level of evidence remains low.

DAPS score - a novel score for prediction of significant fibrosis in incidentally detected asymptomatic hepatitis B subjects. Clin Exp Hepatol 2023; 9:9-13. [PMID: 37064839 PMCID: PMC10090992 DOI: 10.5114/ceh.2023.124518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 11/12/2022] [Indexed: 04/18/2023] Open
Abstract
Aim of the study Significant fibrosis is an indication for treatment in hepatitis B patients with normal transaminase levels. The present study was aimed at analyzing the factors associated with significant fibrosis in incidentally detected asymptomatic hepatitis B subjects (IDAHS) and developing a model for fibrosis prediction for use in low-resource settings. Material and methods This is a single-center retrospective analysis of data on IDAHS who had undergone FibroScan. The variables associated with significant fibrosis in the derivation cohort were subjected to multivariate analysis by logistic regression. The model was applied to the validation cohort for fibrosis prediction. Results A total of 299 patients (mean age: 42.6 years, males: 63.2%) were included in the model derivation. Significant fibrosis was found in 27.4% (82/299) of the patients and 16.8% (30/178) of those with normal transaminase. On multivariate analysis, age, lower platelet count, and presence of diabetes were associated with fibrosis. Serum glutamic pyruvic transaminase (SGPT) was included in the model as it was nearing towards in multivariate analysis. The DAPS (diabetes, age, platelet count, SGPT) score was proposed with equal weightage to each variable. Based on the cumulative score, patients were categorized as having low risk (DAPS score 0-2) or high risk (DAPS score 3-4). The specificity of the model in derivation and validation cohorts was 98.2% and 97.6%, respectively, while the accuracy was 83.6% and 80%, respectively. Conclusions Approximately 17% of IDAHS with normal transaminase have significant fibrosis. The DAPS score can be used easily as a bedside tool for assessment of significant fibrosis in IDAHS with excellent specificity.

Influence of biliary stents on the diagnostic outcome of endoscopic ultrasound-guided tissue acquisition from solid pancreatic lesions: a systematic review and meta-analysis. Clin Endosc 2023; 56:169-179.

Abstract
BACKGROUND/AIMS This meta-analysis analyzed the effect of an indwelling biliary stent on endoscopic ultrasound (EUS)-guided tissue acquisition from pancreatic lesions. METHODS A literature search was performed to identify studies published between 2000 and July 2022 comparing the diagnostic outcomes of EUS-TA in patients with or without biliary stents. For non-strict criteria, samples reported as malignant or suspicious for malignancy were included, whereas for strict criteria, only samples reported as malignant were included in the analysis. RESULTS Nine studies were included in this analysis. The odds of an accurate diagnosis were significantly lower in patients with indwelling stents using both non-strict (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.52-0.90) and strict criteria (OR, 0.58; 95% CI, 0.46-0.74). The pooled sensitivity with and without stents were similar (87% vs. 91%) using non-strict criteria. However, patients with stents had a lower pooled sensitivity (79% vs. 88%) when using strict criteria. The sample inadequacy rate was comparable between groups (OR, 1.12; 95% CI, 0.76-1.65). The diagnostic accuracy and sample inadequacy were comparable between plastic and metal biliary stents. CONCLUSION The presence of a biliary stent may negatively affect the diagnostic outcome of EUS-TA for pancreatic lesions.

Tenofovir versus entecavir for tertiary prevention of hepatocellular carcinoma in chronic hepatitis B infection after curative therapy: A systematic review and meta-analysis. J Viral Hepat 2023; 30:108-115. [PMID: 36321967 DOI: 10.1111/jvh.13766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 09/20/2022] [Accepted: 10/24/2022] [Indexed: 11/07/2022]
Abstract
Entecavir (ETV) and Tenofovir disoproxil fumarate (TDF) are the first-line drugs for the treatment of chronic hepatitis B virus (HBV). However, the impact of these two antiviral agents on the outcome of HBV-related hepatocellular carcinoma (HCC) after curative therapy remains to be explored. The purpose of the present study was to compare the effect of ETV and TDF on recurrence and mortality after curative treatment for HBV-related HCC. A comprehensive literature search of multiple electronic databases was conducted from 2000 to January 2022 for studies comparing ETV and TDF for HBV-related HCC patients after curative therapy. The adjusted hazard ratios (aHR) were pooled using a random-effects model. A total of nine studies with 5298 patients were included in the final meta-analysis. TDF was associated with a lower risk of HCC recurrence [aHR 0.73, 95% confidence interval (CI) 0.65-0.81] compared to HCC. TDF reduced the risk of late recurrence compared to ETV (aHR 0.58, 95% CI 0.45-0.76) but not early recurrence (aHR 0.88, 95% CI 0.76-1.02). The mortality risk was also lower with TDF compared to ETV (aHR 0.62, 95% CI 0.50-0.77). TDF was associated with a lower risk of recurrence and mortality than ETV after resection or ablation of HBV-related HCC. Further prospective randomized controlled studies are warranted to validate these results.

Abstract
Introduction Anomalous pancreaticobiliary duct union (APBDU) is defined by the abnormal position of the junctional union of the common bile duct and the pancreatic duct, outside the duodenal wall above the influence of sphincter of Oddi, associated with choledochal cysts and biliary malignancies. APBDU may rarely present as recurrent acute pancreatitis (RAP) or chronic pancreatitis (CP). We aimed to study the prevalence of patients with APBDU presenting as RAP or CP and their response to endotherapy. Methods A retrospective audit of the prospectively maintained endoscopy database at our institute between January 2018 and November 2020 was conducted to identify cases of APBDU presenting as RAP or CP. Details of investigations, endoscopic retrograde cholangiopancreatography (ERCP) findings, and follow-up till six months were noted. Results We identified 26 cases of APBDU, of which five (19.2%) cases presented as RAP or CP. Of these five patients, two had RAP, while three presented with CP (median: 11 years; range: 4-25 years). Magnetic resonance cholangiopancreatography (MRCP) showed APBDU in three patients. One patient with RAP had a Komi type IIIB anomaly. Another patient with RAP had a rare anomaly with absent ventral PD, with the bile duct communicating and draining through the dorsal duct. Two patients with CP had a long common channel with Komi IIA anomaly. One patient with CP had IIIC2 anomaly. Pancreas divisum was noted in three patients, all of whom underwent minor-papilla sphincterotomy. Successful pancreatic stent placement was performed in all patients. Over one year of follow-up, patients with CP had a significant decrease in pain as measured by the visual analog scale. Those with RAP had no further episodes of pancreatitis. Conclusion APBDU is a rare cause of RAP and CP in young patients, occasionally missed on MRCP. RAP and CP caused by APBDU show good response to endotherapy.

Abstract
PURPOSE Most studies identifying risk factors for post-hepatectomy biliary leaks (PHBLs) have relatively small proportions of major hepatectomies. A simplified predictive score to identify high risk patients is necessary in order to investigate the efficacy of mitigation strategies. METHODS A retrospective analysis of a prospectively maintained database of liver resections from a high-volume cancer center was performed. Multivariate regression was utilized for identification of risk factors and development of the predictive score. RESULTS A total of 862 patients underwent a curative hepatic resection over 10 years, of whom 146 (16.9%) developed a biliary leak; 85 (9.86%), 52 (6.03%), and 9 (1.04%) patients had a grade A, B, and C leak respectively. A biliary-enteric anastomosis [OR 5.1 (95% CI 2.45-10.58); p < 0.001], a central [OR 4.33 (95% CI 1.25-14.95); p = 0.021] or an extended hepatectomy [OR 4.29 (95% CI 1.52-12.12); p = 0.006], liver steatosis [OR 2.28 (95% CI 1.09-4.77); p = 0.027], and blood loss of ≥ 2000 mL [OR 2.219 (95% CI 1.15-4.27); p = 0.017] were identified as independent predictors of a clinically significant biliary leak and were assigned 1 point each to develop the biliary leak score. Clinically significant biliary leaks were seen in 11 (2.79%), 20 (6.38%), 19 (15.4%), 9 (56.3%), and 1 (100%) patients with scores of 0, 1, 2, 3, and 4 respectively (p < 0.001). CONCLUSION A biliary-enteric anastomosis, a central or extended hepatectomy, liver steatosis, and blood loss ≥ 2L combined result in a simple predictive score for clinically significant biliary leaks.

Abstract
BACKGROUND The present guidelines stratify endoscopic ultrasound-guided tissue acquisition (EUS-TA) as a high-bleeding risk procedure in patients on antithrombotics. However, the data regarding the same are conflicting. Therefore, this meta-analysis aimed to analyze the bleeding event rates associated with EUS-TA in patients receiving antithrombotic therapy. METHODS A literature search from January 2000 to August 2022 was done for studies on EUS-guided TA in patients receiving antithrombotics. The primary outcome was incidence of overall and major bleeding. Pooled event rates across studies were expressed with summative statistics. RESULTS A total of 12 studies were included in the meta-analysis. The pooled risk of overall bleeding and major bleeding in patients on antithrombotics was 2.0% (0.6-3.4) and 0.8% (0.0-1.6), respectively. In patients taking thienopyridine or anticoagulants, the pooled risk of overall bleeding and major bleeding was 2.4% (0.9-3.9) and 1.7% (0.4-3.1), respectively. Patients on antithrombotics had a higher odd of overall bleeding (OR 2.12, 1.20-3.83) and major bleeding (OR 3.58, 1.11-11.52) compared to controls. The odds of overall bleeding (OR 0.95, 95%CI 0.38-2.42) and major bleeding (OR 1.57, 95%CI 0.45-5.54) were comparable between patients on antithrombotics who continued and those who discontinued it preprocedural. CONCLUSION Despite an increase risk of bleeding with EUS-TA in patients on antithrombotics, the pooled incidence remains low. Compared to the previous guidelines stating thienopyridine use as high risk for bleeding, the present analysis showed a bleeding rate of less than 1%. Discontinuing antithrombotics prior to EUS-TA does not reduce the bleeding risk significantly, requiring strict monitoring.

An Update to the Malthus Model for Radiotherapy Utilisation in England. Clin Oncol (R Coll Radiol) 2023; 35:e1-e9.

Abstract
AIMS The Malthus Programme predicts national and local radiotherapy demand by combining cancer incidence data with decision trees detailing the indications, and appropriate dose fractionation, for radiotherapy. Since the last model update in 2017, technological advancements and the COVID-19 pandemic have led to increasing hypofractionation of radiotherapy schedules. Indications for radiotherapy have also evolved, particularly in the context of oligometastatic disease. Here we present a brief update on the model for 2021. We have updated the decision trees for breast, prostate, lung and head and neck cancers, and incorporated recent cancer incidence data into our model, generating a current estimate of fraction demand for these four cancer sites across England. MATERIALS AND METHODS The decision tree update was based on evidence from practice-changing randomised controlled trials, published guidelines, audit data and expert opinion. Site- and stage-specific incidence data were taken from the National Disease Registration Service. We used the updated model to estimate the proportion of patients who would receive radiotherapy (appropriate rate of radiotherapy) and the fraction demand per million population at a national and Clinical Commissioning Group level in 2021. RESULTS The total predicted fraction demand has decreased by 11.4% across all four cancer sites in our new model, compared with the 2017 version. This reduction can be explained primarily by greater use of hypofractionated treatments (including stereotactic ablative radiotherapy) and a shift towards earlier stage presentation. The only large change in appropriate rate of radiotherapy was an absolute decrease of 3% for lung cancer. CONCLUSIONS Compared with our previous model, the current version predicts a reduction in fraction demand across England. This is driven principally by hypofractionation of radiotherapy regimens, using technology that requires increasingly complex planning. Treatment complexity and local service factors need to be taken into account when translating fraction burden into linear accelerator demand or throughput.

Does a coaxial double pigtail stent reduce adverse events after lumen apposing metal stent placement for pancreatic fluid collections? A systematic review and meta-analysis. Ther Adv Gastrointest Endosc 2023; 16:26317745231199364. [PMID: 37736486 PMCID: PMC10510348 DOI: 10.1177/26317745231199364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Accepted: 08/10/2023] [Indexed: 09/23/2023] Open
Abstract
Background Lumen apposing metal stents (LAMSs) have a higher clinical success rate for managing pancreatic fluid collections. But they are associated with adverse events (AEs) like bleeding, migration, buried stent, occlusion, and infection. It has been hypothesized that placing a double pigtail stent (DPS) within LAMS may mitigate these AEs. The present systematic review and meta-analysis were conducted to compare the outcome and AEs associated with LAMS with or without a coaxial DPS (LAMS-DPS). Methods A comprehensive literature search of three databases from January 2010 to August 2022 was conducted for studies comparing the outcome and AEs of LAMS alone and LAMS-DPS. Pooled incidence and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated for all the dichotomous outcomes. Results Overall, eight studies (n = 460) were included in the final analysis. The clinical success rate (RR 1.00, 95% CI: 0.87-1.14) and the risk of overall AEs (RR 1.60, 95% CI: 0.95-2.68) remained comparable between both groups. There was no difference in the risk of bleeding between LAMS alone and LAMS-DPS (RR 1.80, 95% CI: 0.83-3.88). Individual analysis of other AEs, including infection, stent migration, occlusion, and reintervention, showed no difference in the risk between both procedures. Conclusion The present meta-analysis shows that coaxial DPS within LAMS may not reduce AE rates or improve clinical outcomes. Further larger studies, including patients with walled-off necrosis, are required to demonstrate the benefit of coaxial DPS within LAMS.

Abstract
BACKGROUND Patients with moderate-severe cholangitis require urgent/early biliary drainage and failed endoscopic retrograde cholangiopancreatography (ERCP) warrants use of percutaneous drainage. While endoscopic ultrasound-guided biliary drainage (EUS-BD) has evolved as an effective salvage modality but its safety and efficacy data in moderate-severe cholangitis are limited. PATIENTS AND METHODS All consecutive moderate-severe cholangitis patients, with failed/technically non-feasible ERCP requiring EUS-BD in two tertiary care centers were included. Baseline laboratory and demographic parameters were documented. Technical and clinical success were primary outcome measures. Additionally, effective biliary drainage, adverse events due to procedure, hospital stay, ICU stay, and mortality were noted. RESULTS Of the 49 patients (23 male; 46.9%) presenting with moderate/severe cholangitis, 23 (46.9%) had severe cholangitis. The median Charleston comorbidity index was 7.0 (IQR 2.0). Majority had malignant disease (87.8%) and 25 (51.0%) had inaccessible papilla. Technical success was achieved in 48 cases (98.0%), while clinical success with improvement of cholangitis was noted in 44 of 48 cases (91.7%). Effective biliary drainage was noted in 85.4% (41/48) cases. Adverse events in the form of mostly bleeding and bile leak were noted in 5 cases (10.2%) but managed conservatively. Distal obstruction exhibited significantly better clinical success (100% vs. 78.9%; p = 0.02) than hilar obstruction. Severe cholangitis had significantly lower clinical success (81.8% vs. 100%; p = 0.04) than moderate cholangitis. CONCLUSION EUS-BD can be a safe and effective alternative option for patients with moderate to severe cholangitis, even with significant pre-morbid conditions, with acceptable adverse events rate.

Abstract
Introduction Colonic self-expanding metal stent (SEMS) placement is the preferred method for palliation of malignant colonic obstruction. We analyzed outcomes of patients who underwent colonic SEMS placement for palliation at a tertiary care oncology center in Western India.
Methods Retrospective review of the endoscopy database was done for patients who underwent colonic SEMS placement at our center between January 2013 and September 2021. Demographic details, intent of stent placement, site of obstruction, length of stricture, technical success of stenting, clinical success, and complications (both immediate and long term) were noted.
Results Sixty-one patients underwent colonic SEMS placement during the study period (mean age 53.6 years, 50.7% men). Obstruction was due to primary colonic malignancy in 43 (70.5%) patients and extracolonic malignancies in 18 (29.5%) patients. Most common extracolonic malignancy was gallbladder cancer in 8 (44.4%) patients. Most common site of obstruction was sigmoid colon in 18 (29.5%) patients. Proximal colonic obstruction was seen in 17 (27.9%) patients. Peritoneal metastases were seen in 26 (42.6%) patients. Colonoscopy revealed an impassable stenosis in 58 (95.1%) patients. Median length of stricture was 5 cm (range 2–9 cm). Technical success was achieved in 98.3% (60/61). Clinical success was achieved in 51 (86.4%) patients. Perforation during colonic SEMS placement was seen in 2 (3.4%) patients. Stent migration was seen in 3 (5.9%) patients, needing surgery for retrieval in all 3 patients. Over a median follow-up of 9 months (0–21 months), stent block was seen in 7 (13.7%) patients. Stent block developed after a median period of 6 months. Of these patients, three patients underwent SEMS placement within the SEMS and the other four patients underwent surgery.
Conclusion Colonic SEMS placement achieves good palliation of malignant colonic obstruction in approximately 87% patients. Long-term complications like obstruction occur in a few patients after a median duration of 6 months.

Abstract
Abstract
Background In clinical practice, decision about management of choledocholithiasis is driven by availability of resources and expertise, patients and healthcare professional preferences. This survey is aimed to describe the approach of physicians and surgeons for the management of choledocholithiasis.
Method A 36-question online survey was conducted using Google Forms on various aspects of management of choledocholithiasis.
Results The responses from 323 participants were included, of which 202 (62.54%) were physicians and 121 (37.46%) were surgeons. The proportion of responders who do not follow American or European Society of Gastrointestinal Endoscopy guidelines is associated with increasing age and experience of responders (p = 0.0001), while place of work (private vs. teaching) and broad specialty (physician vs surgeon) are not associated (p >0.05). For patients with high likelihood of choledocholithiasis, 123 (38.1%) participants prefer to do endoscopic ultrasound/magnetic resonance cholangiopancreatography (EUS/MRCP) rather than directly performing endoscopic retrograde cholangiopancreatography/intraoperative cholangiography (ERCP/IOC). For intermediate likelihood, MRCP is more commonly preferred compared with EUS, due to local availability (44%), expertise (39.6%), healthcare professionals preference (30.7%), and patients preference (17.3%). For difficult common bile duct (CBD) stones, short biliary sphincterotomy with large balloon sphincteroplasty (59.4%), followed by laparoscopic CBD exploration are commonly used approaches. Prophylactic CBD stent placement after ERCP and CBD clearance is common practice. Preoperative ERCP followed by cholecystectomy is more preferred approach than cholecystectomy and CBD exploration.
Conclusion There is considerable variability in the management of choledocholithiasis. The practices such as use of EUS/MRCP for high likelihood group, use of prophylactic CBD stent placement after ERCP and CBD clearance, and use of single stage approach especially in patient with intermediate likelihood group should be addressed in future studies.

Outcomes and predictors of response to endotherapy in pancreatic ductal disruptions with refractory internal and high-output external fistulae. Ann Hepatobiliary Pancreat Surg 2022; 26:347-354. [PMID: 35995583 PMCID: PMC9721253 DOI: 10.14701/ahbps.22-002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/08/2022] [Accepted: 03/17/2022] [Indexed: 12/15/2022] Open
Abstract
Backgrounds/Aims Endoscopic retrograde cholangiopancreatography (ERCP) remains the primary treatment for a subset of patients with pancreatic fistulae. The objective of this study was reporting outcomes of ERCP and predictors of resolution in patients with pancreatic fistulae refractory to conservative therapy. Methods Retrospective review of patients who underwent ERCP and pancreatic stent placement for pancreatic fistula not responding to medical therapy was performed. Clinical features, laboratory parameters, radiological features and pancreatogram findings were noted. Clinical resolution of fistula was the primary outcome measure. Results Sixty-eight patients underwent ERCP for high-output pancreatic fistula (Mean age 34.1 years, 91.1% males, 35/68 chronic pancreatitis, 52.9% alcohol etiology). Internal fistulae (pancreatic ascites, pleural effusion, or pericardial effusion) were seen in 55 (80.9%) patients and external fistula in 13 (19.1%) patients. Technical success for ERCP was 92.6% (63/68). Leak was seen in 98.4% (62/63). The most common leak site was body (69.8%). Multiple leak sites were seen in 23.1%. Pancreatic stricture was found in 36.5%. In 44 (69.4%) patients, stent was placed beyond the site of the leak. Resolution at six weeks was achieved in 76.4% (52/68). On univariate and multivariate analyses, placement of stent beyond site of leak was significantly associated with resolution of high-output fistulae (3/41 [7.3%] vs. 5/19 [26.3%], p = 0.03; odds ratio: 6.5, 95% confidence interval: 1.211-34.94). Conclusions In our experience, ERCP was successful in 76% of patients with pancreatic fistulae refractory to conservative therapy. Stent placement beyond the site of leak was associated with higher resolution of fistulae.

Magnetic resonance cholangiopancreatography versus endoscopic ultrasound for diagnosis of choledocholithiasis: an updated systematic review and meta-analysis. Surg Endosc 2022; 37:2566-2573. [PMID: 36344899 DOI: 10.1007/s00464-022-09744-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 10/14/2022] [Indexed: 11/09/2022]
Abstract
INTRODUCTION Both endoscopic ultrasound (EUS) and magnetic resonance cholangiopancreatography (MRCP) are used for the diagnosis of choledocholithiasis (CDL). Previous studies have shown conflicting results regarding the optimal diagnostic strategy for suspected CDL; hence, this meta-analysis was conducted. METHODS A comprehensive search of literature from 1990 till April 2022 was done of three databases for studies comparing EUS and MRCP to diagnose CDL. RESULTS A total of 12 studies were identified. The pooled sensitivity and specificity for EUS were 0.96 [95% confidence interval (CI) 0.92-0.98], and 0.92 (95% CI 0.85-0.96), respectively. The pooled sensitivity and specificity for MRCP were 0.85 (95% CI 0.78-0.90) and 0.90 (95% CI 0.79-0.96), respectively. EUS had a higher relative sensitivity [Relative risk (RR) 1.12, 95% CI 1.05-1.19], a higher diagnostic accuracy (Odds ratio 1.98, 95% CI 1.35-2.90) but comparable specificity (RR 1.02, 95% CI 0.96-1.08) with MRCP. CONCLUSION There is little difference concerning specificity, although EUS likely provides a higher sensitivity and accuracy for diagnosing CDL, compared to MRCP.

Seroprevalence of Hepatitis B Virus Among Pregnant Women in India: A Systematic Review and Meta-Analysis. J Clin Exp Hepatol 2022; 12:1408-1419. [PMID: 36340309 PMCID: PMC9630021 DOI: 10.1016/j.jceh.2022.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 08/16/2022] [Indexed: 12/12/2022] Open
Abstract
Objectives Hepatitis B virus (HBV) infection during pregnancy is associated with perinatal transmission contributing to the pool of HBV infection in the population. There is a wide variation in the reported data on the seroprevalence of HBV in pregnant patients from various parts of India. Hence, a systematic review and meta-analysis was conducted to determine the pooled seroprevalence of HBV and its associated demographic factors. Methods A comprehensive literature search of Medline, Scopus, and Google Scholar was conducted from January 2000 to April 2022 for studies evaluating the prevalence of HBV in pregnant patients from India. Results A total of 44 studies with data on 272,595 patients were included in the meta-analysis. The pooled prevalence of hepatitis B surface antigen (HBsAg) in pregnant women was 1.6% [95% confidence interval (CI), 1.4-1.8]. Among patients with HBsAg positivity, the pooled prevalence of hepatitis B e antigen was 26.0% (95%CI 17.4-34.7). There was no significant difference in the odds of HBV seroprevalence based on the age (<25 years vs. > 25 years) [odds ratio (OR) 1.07, 95%CI 0.74-1.55], parity (primipara vs. multipara) (OR 1.09, 95%CI 0.70-1.70) or area of residence (urban vs. rural) (OR 0.88, 95%CI 0.56-1.39). However, the odds of HBV seroprevalence in those with no or primary education was higher than in those with secondary level education or higher (OR 2.29, 95%CI 1.24-4.23). Prior history of risk factors was present in 13.5-22.7% of patients indicating a vertical mode of acquisition. Conclusion There is a low endemicity of HBV among pregnant women in India. Risk factors are seen in less than 25% of the cases, indicating vertical transmission as the predominant mode of acquisition, which can be reduced by improving vaccination coverage.

Abstract
Background and aims Increasing incidence of hepatocellular carcinoma (HCC) in India is a matter of concern and need for adequate profiling and streamlining management strategies cannot be over-emphasized. Methods This is a prospective multi-centric observational cohort study comprising of an oncology center, one university tertiary hospital with specialized hepatology service, one public hospital with gastroenterology service, and a private liver transplant center located within a 3-km radius. The demographic and clinical parameters were recorded on a prospectively maintained database. The clinical profile, demographics, characteristics of HCC and the allocated treatment were noted and compared among the four centers. Results In total, 672 patients were enrolled from June 2016 till January 2020. Abdominal pain (64.3%) and weight loss (47.3%) were the most common symptoms. Most common identified etiology was hepatitis B (39%). The cancer center received lesser patients with hepatitis C and those with advanced stage of HCC. The private transplant center reported the highest proportion of NASH, which was also significantly higher in those belonging to higher socioeconomic strata, and lowest proportion of alcoholic cirrhosis. Metastasis was seen in almost one-fifth (19%) cases at diagnosis. Portal vein thrombosis was evident in 40%. Adherence to treatment guidelines was seen in three-fourth cases (76%). Conclusions Hepatitis B is the most common underlying cause for HCC, whereas other causes like NASH are on the rise. Etiologic profile may vary with selective specialization of centers catering to patients with HCC. Adherence to guideline while allocating treatment was high among all centers with highest non-adherence in BCLC A.

Outcomes of thin versus thick-wire snares for cold snare polypectomy: a systematic review and meta-analysis. Clin Endosc 2022; 55:742-750. [PMID: 36347525 PMCID: PMC9726435 DOI: 10.5946/ce.2022.141] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 06/27/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND/AIMS Cold snare polypectomy (CSP) is commonly used for the resection of colorectal polyps ≤10 mm. Data regarding the influence of snare type on CSP effectiveness are conflicting. Hence, this meta-analysis aimed to compare the outcomes and safety of thin- and thick-wire snares for CSP. METHODS A comprehensive search of the literature published between 2000 and 2021 was performed of various databases for comparative studies evaluating the outcomes of thin- versus thick-wire snares for CSP. RESULTS Five studies with data on 1,425 polyps were included in the analysis. The thick-wire snare was comparable to the thin-wire snare with respect to complete histological resection (risk ratio [RR], 1.03; 95% confidence interval [CI], 0.97-1.09), overall bleeding (RR, 0.98; 95% CI, 0.40-2.40), polyp retrieval (RR, 1.01; 95% CI, 0.97-1.04), and involvement of submucosa in the resection specimen (RR, 1.28; 95% CI, 0.72-2.28). There was no publication bias and a small study effect, and the relative effects remained the same in the sensitivity analysis. CONCLUSION CSP using a thin-wire snare has no additional benefit over thick-wire snares in small colorectal polyps. Factors other than snare design may play a role in improving CSP outcomes.
