Pure cut vs. Endocut in endoscopic biliary sphincterotomy: Systematic review and meta-analysis of randomized clinical trials
Abstract
Background and study aims Biliary sphincterotomy is a crucial step in endoscopic retrograde cholangiopancreatography (ERCP), a procedure known to carry a 5% to 10% risk of complications. The relationship between Pure cut, Endocut, post-ERCP pancreatitis (PEP) and bleeding is unclear. This systematic review and meta-analysis compared these two current types and their relationships with adverse events.
Patients and methods This systematic review involved searching articles in multiple databases until August 2023 comparing pure cut versus Endocut in biliary sphincterotomy. The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).
Results A total of 987 patients from four randomized controlled trials were included. Overall pancreatitis: A higher risk of pancreatitis was found in the Endocut group than in the Pure cut group (P=0.001, RD=0.04 [range, 0.01 to 0.06]; I2=29%). Overall immediate bleeding: Statistical significance was found to favor Endocut, (P=0.05; RD=–0.15 [range, –0.29 to –0.00]; I2=93%). No statistical significance between current modes was found in immediate bleeding without endoscopic intervention (P=0.10; RD=–0.13 [range, –0.29 to 0.02]; I2=88%), immediate bleeding with endoscopic intervention (P=0.06; RD=–0.07 [range, –0.14 to 0.00]; I2=76%), delayed bleeding (P=0.40; RD=0.01 [range, –0.02 to 0.05]; I2=72%), zipper cut (P=0.58; RD=–0.03 [range, –0.16 to 0.09]; I2=97%), perforation (P=1.00; RD=0.00 [range, –0.01 to 0.01]; I2=0%) and cholangitis (P=0.77; RD=0.00 [range, –0.01 to 0.02]; I2=29%).
Conclusions The available data in the literature show that Endocut carries an increased risk for PEP and does not prevent delayed or clinically significant bleeding, although it prevents intraprocedural bleeding. Based on such findings, Pure cut should be the preferred electric current mode for biliary sphincterotomy.

Introduction
Endoscopic biliary sphincterotomy is a crucial step in endoscopic retrograde cholangiopancreatography (ERCP), a procedure known to carry a 5% to 10% risk of complications, including post-ERCP pancreatitis (PEP), bleeding, cholangitis, perforation, sepsis, and even death [1] [2] [3] [4] [5]. Two commonly used current modes in sphincterotomy are Pure cut and Endocut (or pulsed cut) [6] [7] [8].
Pure cut utilizes a pure sine wave with high frequency and lower voltage, with arcs that have a voltage higher than 200 volts and are generated as soon as vaporization of liquid in the tissue creates a small gap between the cutting wire and tissue in the duodenal papilla (ERBE Elektromedizin GmbH. Endo CUT I. Tubingen: ERBE; 2016). Endocut (types 2 or 3) uses coagulation between the cutting cycles. Coagulation presents a very short active sinus wave (6% to 10% of cycle) with a more extended cooling period (inactivated 90%-94% of cycle, lasting 720–750 ms) [9] [10] [11] [12]. Therefore, in this text, Endocut refers to types 2 and 3.
Thermal injury from the coagulation effect of Endocut can lead to local edema in the major papilla, potentially impairing pancreatic duct drainage and predisposing PEP, as some studies suggest [11] [12] [13] [14]. However, the most recent meta-analysis by Funari et al. did not find statistical evidence supporting this claim [15]. On the other hand, Endocut has been shown to decrease intraprocedural bleeding, likely due to its coagulation effect [11] [12]. However, previous studies did not show that Endocut is capable of reducing delayed bleeding with clinical repercussions [15] [16].
Thus, the primary objective of our study was to compare these two current modes (pure cut and Endocut) considering post-ERCP adverse events (AEs), especially PEP and bleeding. Therefore, we intended to investigate whether the available literature could support selection of the optimal current mode during biliary sphincterotomy, ultimately enhancing patient safety and clinical outcomes related to this procedure.

Eligibility criteria
Only randomized clinical trials (RCTs) comparing pure cut and Endocut modes for endoscopic biliary sphincterotomy were eligible for inclusion. The exclusion criteria were as follows: studies that discussed any current mode other than Endocut or pure cut, patients younger than age 18 years, animal studies, retrospective studies, and patients with significant anatomical alterations (e.g., Roux-en-Y and Billroth II).
#
Search strategy, study selection and data collection process
For this meta-analysis, a comprehensive search was conducted independently by two authors (LBO and MPF) across multiple databases, including Medline, Embase, Lilacs, Central Cochrane, and Google Scholar, spanning from inception until June 2023. The search process involved meticulously reviewing all titles within these databases, removing any duplicate entries. Subsequently, articles that did not meet the predetermined inclusion criteria were excluded. In the second phase, all abstracts of the remaining articles were thoroughly assessed. From this selection, both reviewers cross-referenced the results to ensure accuracy. In cases where there was uncertainty or disagreement between the reviewers, a third reviewer (ASTK) was consulted to reach a consensus. To facilitate data extraction, the researchers utilized standardized Excel spreadsheets to record information related to the dichotomous outcomes, including pancreatitis and its grades, intraprocedural bleeding with and without the need for endoscopic intervention, delayed bleeding, uncontrolled sphincterotomy, perforation, and cholangitis [1].
#
Search strategy
Keywords for the strategy search for PubMed (Medline) were papillotomy, sphincterotomy, retrograde cholangiopancreatography, endoscopic, cut, blend and Endocut. The full strategy:
(((((papillotomy OR Sphincterotomy OR Sphincterotomies OR Sphincterotome OR Sphincteroplasty OR Sphincteroplasties) OR ((Retrograde Cholangiopancreatography, Endoscopic OR Cholangiopancreatographies, Endoscopic Retrograde OR Endoscopic Retrograde Cholangiopancreatographies OR Retrograde Cholangiopancreatographies, Endoscopic OR Endoscopic Retrograde Cholangiopancreatography OR ERCP) AND (cut OR electrosurg* OR knife OR blend OR electric* OR blend OR electrocautery OR cautery OR coagulation OR endocut)))))).
#
Data analysis
All outcomes were assessed by dichotomous variables using the Mantel-Haenszel test to determine risk differences. We used a confidence interval (CI) of 95% and a significant P < 0.05. We preferred to apply CI rather than prediction interval because the Cochrane Handbook for Systematic Reviews of Interventions explicitly states that a minimum of 10 studies is typically recommended for application of prediction intervals, and in our meta-analysis, we had a total of four studies. Nevertheless, CI was used in other recent meta-analyses on this topic [15] [16]. We assessed the heterogeneity of the forest plot by the Higgins test (I²). If I² is 0% to 40%, the heterogeneity might not be significant; if 30% to 60%, the results may represent substantial heterogeneity; and if 75% to 100%, they represent considerable heterogeneity [19]. A sensitivity analysis was performed utilizing a funnel plot to identify potential outliers.
If exclusion of specific studies from the meta-analysis resulted in a homogenous dataset, those studies were considered true outliers and permanently excluded. In such cases, the fixed-effect model was employed for the final analysis. However, if no outliers were identified or if heterogeneity remained high despite excluding outliers, we opted for the random-effects model. This approach helps mitigate the impact of heterogeneity on the overall findings, ensuring a more robust and reliable conclusion.
In the case of moderate or high heterogeneity, if I²>50%, the random-effects model was used. Otherwise, in the case of low heterogeneity, I² <50%, and the fixed-effects test was performed. All direct analyses were carried out in RevMan 5 software (Review Manager version 5.4.1—Cochrane Collaboration Copyright) [20].
#
Methodology quality and risk of bias in individual studies
To comprehensively assess the overall quality of each outcome analysis and the respective RCTs, we followed the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) standards [21], utilizing GRADEpro software for guideline development tools (GRADEpro Guideline Development Tool [Software]. McMaster University and Evidence Prime, 2022).
Biases present in the selected RCTs were carefully assessed using the Cochrane Risk of Bias Tool (Rob2) ([Fig. 2]) [22]. Evaluation of study quality encompassed patient selection, comparability of the study groups, and outcome measures. Each RCT was meticulously analyzed using RoB 2, focusing on aspects such as randomization and allocation concealment (selection bias), blinding of participants and personnel (performance bias), blinding of outcome assessment (detection bias), handling of incomplete outcome data (attrition bias), adherence to outcome and prognostic factors, intention-to-treat analysis, sample size calculation, and selective reporting.

![Zoom Image](/products/assets/desktop/css/img/icon-figure-zoom.png)
To ensure consistency and accuracy in bias assessment using RoB 2 and the GRADE analysis, two independent reviewers (LBO and MPF) conducted the evaluations. In instances of disagreements, a third reviewer (ASTK) was consulted to achieve a consensus and ensure the reliability of the findings.
#
Outcome definitions
There is no standardized graduation for immediate (intraprocedural) bleeding, and the included studies use different definitions. To homogenize this analysis, we classified the study definitions into either self-limited bleeding or bleeding with the need for endoscopic intervention. Delayed bleeding was defined and graded according to the Cotton criteria [23].
For meta-analysis purposes, we only considered perforations related to biliary sphincterotomy, classified as Stapfer II [24].
PEP was defined according to Cotton’s criteria because Funari, Norton, and Kida mentioned Cotton’s classification. Ellahi mentioned “according to a consensus definition.” However, we considered Cotton because this was an abstract from 2001, and at that time, Cotton’s criteria were the only classification in this theme (created in 1991), while Atlanta's Classification was developed in 2012 [23].
In this review all AEs described in the studies in question are mentioned. However, our focus will be on more in-depth exploration of procedure-related AEs, which are notably prevalent in this context. Specifically, we delve into issues such as pancreatitis, bleeding, perforation, zipper cut, and cholangitis—areas of particular interest to us. Consequently, when we reference AEs in this review, we are specifically alluding to those previously mentioned.

Discussion
To date, this is the fourth meta-analysis comparing Endocut and Pure cut for sphincterotomies but the only one to include all four currently available RCTs. The three previously published meta-analyses (Hedjoudje 2021, Funari 2018, Verma 2007) demonstrated similar results: lower rates of immediate bleeding with pure cut and no difference for PEP, delayed bleeding, and other AEs [15] [16] [25] [26]. Based on such findings, an important recent guideline recommends using Endocut to perform sphincterotomies [12].
It is important to emphasize that the studies used different types of electrical surgery units that influence electric power and details of the type of coagulation. This is because they were performed in different countries and years, so they cannot be homogeneous. However, the most frequent and concerning post-ERCP AE is PEP. The recent publication of a large RCT has made us hypothesize that Endocut is a risk factor for PEP, which corroborates the principles of electrosurgery [12] [27] [28] [29]. Theoretically, local edema due to pronounced thermal injury from the coagulation modes could obstruct the pancreatic duct, favoring PEP. Our results confirm this assumption. Nevertheless, it is unclear whether associated measures, such as use of rectal nonsteroidal anti-inflammatory drugs (NSAID), could further enhance the protective effect of Pure cut or if moderate and severe pancreatitis could also be reduced.
Immediate bleeding with the need for endoscopic intervention during the index ERCP seems to have a trend in favor of Endocut. This result corroborates the aforementioned meta-analyses [7] [8] [29]. Notably, however, the reported intraprocedural bleeding had no clinical repercussions, and in all cases it was controlled during the same procedure.
Delayed bleeding was also no different between groups. Some studies have suggested that increased intraprocedural bleeding might be a risk factor for delayed bleeding; however, the extensive series and our results did not corroborate this finding [15] [27] [29] [30]. We speculate that Pure cut allows for a cleaner cut, which increases the chance of identifying and immediately treating bleeding vessels during ERCP. Ultimately, immediate hemostatic control would prevent delayed bleeding. Therefore, Endocut should not be considered a measure to prevent bleeding with clinical repercussions.
Some authors consider Endocut to be safer in terms of uncontrolled sphincterotomy (zipper cut) and sphincterotomy-related perforation [31] [32]. However, our results did not support such a rationale. Regardless, one should note that Pure cut must be used cautiously (quick steps on the pedal activating the electrosurgical unit) to prevent endoscopists from gaining control of the cut, because the generator does not interrupt the cutting cycle automatically [12] [27] [33]. Furthermore, zipper cut and perforation are strongly influenced by other technical factors related to endoscopist experience, which should be considered.
Our study is not exempt from limitations, as inclusion of abstracts was part of our analysis. However, we decided to include those studies because they provided all the essential information to fulfill our eligibility criteria, enabling our analysis. Another limitation is the lack of definition and differentiation between types of immediate bleeding, which was mitigated. We tried to mitigate this by differentiating self-limited from bleeding with the need for endoscopic intervention. Similarly with delayed bleeding follow-up, which was not mentioned in one of the three articles being analyzed in this variable (Ellahi et al), we agreed to consider 7 days. In addition, more than two decades separate the first and last eligible published study, and only the latest study employed the modern electrosurgical settings and generator for the Endocut mode [12] [32]. Furthermore, although the benefits of prophylactic NSAIDs for preventing PEP are well known, none of the included studies employed them [34] [35] [36]. Only one of the included studies used hyperhydration with lactated Ringer’s solution as a preventive measure [37] [38]. Therefore, new studies are warranted to elucidate the effect of overlapping measures in prevention of PEP. Also, endoscopist experience influences the precision of biliary sphincterotomy, reflecting incidence of AEs. However, these data are not detailed in some of the studies [39].
It is important to emphasize that the Endocut effect does not necessarily promote the coagulation effect between the cutting cycles. This term refers specifically to an automatically controlled pure cut with predetermined interruptions [12]. Starting at effect 2 and above effects, this modality includes coagulation modes between cutting cycles. All included studies used the equivalent to effect 2 or higher, reinforcing the role of thermal injury in PEP pathophysiology. Consequently, Endocut effect 1 is an option to use pure cut in a more controlled and safer manner [39].
All figures were generated by the programs mentioned in methods such as RevMan 5 software (all forest plots), risk of bias (RoB 2), and PRISMA guidelines (both PRISMA flow diagram and checklist) [17] [18] [20] [22] [40].
#
Conclusions
In conclusion, based on the discussion, it is possible to decrease PEP incidence with a pure cut without increased bleeding with clinical repercussions.
