Endoscopic Ultrasound-guided Drainage of Patients With Infected Walled-off Necrosis: Which Stent to Choose?

Endoscopic ultrasound (EUS)-guided drainage is the preferred treatment of pancreatic fluid collections (PFC). However, the choice of the stent for EUS-guided drainage in critically ill PFC cases with infected walled-off necrosis (WON) and/or organ failure (OF) remains unknown. Between January 2018 and December 2019, consecutive patients with symptomatic PFC subjected to EUS-guided drainage using biflanged metal stents (BFMS) or double-pigtail plastic stents (DPPS) were compared for technical success, clinical success, duration of the procedure, need for intensive care unit stay, duration of intensive care unit stay, ventilator need, resolution of OF, the duration for resolution of OF, complications, need for salvage percutaneous drainage or surgery and mortality. A subgroup of patients having infected WON with/without OF were analyzed separately. Among 120 patients (84.6% males) with PFC (108 WON, 22 pseudocyst) who underwent EUS-guided drainage, there was no difference in outcome parameters in BFMS and DPPS groups. Among patients with WON, clinical success was significantly higher (96.2% vs. 81.8%, P=0.04), with significantly shorter hospital stay (6 vs. 10 d) and procedure duration (17.18±4.6 vs. 43.6±9.7 min, P<0.0001) in the BFMS group. Among patients with infected WON with/without OF, the clinical success was significantly higher (100% vs. 73.9%, P=0.02), and the duration of the procedure was significantly lower (16.28±4.4 vs. 44.39±10.7, P<0.0001) in BFMS compared with DPPS group. EUS-guided drainage of WON using BFMS scores over DPPS. In patients having infected WON with/without OF, BFMS may be preferred over DPPS.

Multicenter study of lumen-apposing metal stents with or without pigtail in endoscopic ultrasound-guided biliary drainage for malignant obstruction\u2014BAMPI TRIAL: an open-label, randomized controlled trial protocol

BackgroundIt is unclear whether the insertion of an axis-orienting double-pigtail plastic stent (DPS) through biliary lumen-apposing meal stent (LAMS) in EUS-guided choledochoduodenostomy (CDS) improves the stent patency. The aim of this study is to determine whether this technical variant offers a clinical benefit in EUS-guided biliary drainage (BD) for the management of distal malignant biliary obstruction.Methods/designThis is a multicenter open-label, randomized controlled trial with two parallel groups. Eighty-four patients with malignant biliary obstruction will undergo EUS-BD (CDS type) using LAMS in 7 tertiary hospitals in Spain and will be randomized to the LAMS and LAMS plus DPS groups. The primary endpoint is the rate of recurrent biliary obstruction, as a stent dysfunction parameter, detected during follow-up. Secondary endpoints: technical and clinical success (reduction in bilirubin > 50% within 14 days of stent placement), safety, and others (number of reinterventions, time to biliary obstruction, prognostic factors, survival rate).DiscussionThe BAMPI trial has been designed to determine whether the addition of a coaxial axis-orienting DPS through LAMS is superior to LAMS alone to prevent stent dysfunction.Trial registrationClinicalTrials.govNCT04595058.

Lumen apposing metal stents vs. double pigtail plastic stents for the drainage of pancreatic walled-off necrosis.

Few studies compared lumen-apposing metal stents (LAMS) and standard double pigtail plastic stents (PS) for the endoscopic drainage of pancreatic walled-off necrosis (WON). Albeit sometimes large, previously described cohorts display considerable heterogeneity and often pooled together data from several centers, involving multiple operators and techniques. Moreover, they often lack a control group for the comparison of outcomes. The aim of this study was to compare clinical efficacy and safety of PS versus LAMS for the endoscopic drainage of infected WON. Thirty patients were enrolled between 2011 and 2017. The present study is a single-center, 1:1 case-control study. We compared patients undergoing endoscopic drainages of infected WON through LAMS (cases) or PS (controls). The primary endpoint was the clinical efficacy (resolution of the WON/sepsis), the secondary endpoint was safety (procedure-related complications). Cases and controls were homogeneous in terms of etiology and clinical characteristics: 93% of cases and 86.7% of controls were clinically successfully treated, with no significant differences in rates of postoperative infections, bleedings, and stent migrations (respectively 13.3% vs. 21.4%; P=0.65; 13.3% vs. 0%; P=0.48; 13.3% vs. 7.1%; P=1.00). No difference was shown regarding the need for additional percutaneous or surgical treatments (33.3% vs. 13.3%; P=0.39). Cases, however, displayed a significantly prolonged mean hospital stay (90.2 days vs. 18.5 days; P<0.01) and a higher mean number of endoscopic procedures per patient (4.8 vs. 1.5; P<0.01). PS might be not inferior to LAMS for the treatment WONs. Further prospective RCT is needed to compare clinical efficacy and safety in the two groups.

The Combination of Double Pigtail Plastic Stent, Nasocystic Tube and Percutaneous Catheter in Endoscopic Ultrasound-Guided Transluminal Drainage for Peripancreatic Fluid Collection

Background: Endoscopic ultrasound-guided drainage is first-line treatment of Pancreatic fluid collection. The invention of metallic stents has provided a safer and more efficient approach route for internal drainage. But because of the high cost of metal stents, a large number of patients still choose plastic stents, which can help them from the disease with much lower cost. Patients and Methods: Between March to December in 2017, 20 patients with Peripancreatic fluid collections were prospectively enrolled to receive the double pigtail plastic stent with nasocystic tube and/or percutaneous catheter. Results: There were 20 cases of pseudocyst including 4 cases of infected pseudocyst. The causes of the PFC were mainly gallstones (60%), followed with alcohol (30%) and hyperlipoidemia (10%). Technical success was achieved in 100% of the cases. All patients were completely resolved with the evidence of CT scan and clinical evaluation. The mean time for resolution was 15±20 days. The mean follow-up was 3 months. Conclusion: The combination drainage of double pigtail plastic stent with nasocystic tube and/or percutaneous catheter of pancreatic pseudocyst is feasible and efficacious to most patients. Using a titanium clip could prevent migration occurrence. With the economic benefits of plastic stents, they are still wildly used in developing countries.

Double pigtail stent placement as an adjunct to lumen-apposing metal stentsfor drainage of pancreatic fluid collections may not affect outcomes: A multicenter experience.

Background and Objectives:EUS-guided drainage of pancreatic fluid collections (PFCs) has been increasingly performed using lumen-apposing metal stents (LAMS). However, recent data have suggested higher adverse event rates with LAMS compared to double pigtail plastic stents (DPS) alone. To decrease risks, there has been anecdotal use of placing DPS through the LAMS. We aimed to determine whether the placement of DPS through cautery-enhanced LAMS at time of initial placement decreases adverse events or need for reintervention.Methods:We performed a multicenter retrospective study between January 2015 and October 2017 examining patients who underwent EUS-guided drainage of pseudocysts (PP), walled-off necrosis (WON), and postsurgical fluid collection using a cautery enhanced LAMS with and without DPS.Results:There were 68 patients identified at 3 US tertiary referral centers: 44 PP (65%), 17 WON (25%), and 7 PFSC (10%). There were 35 patients with DPS placed through LAMS (Group 1) and 33 with LAMS alone (Group 2). Overall technical success was 100%, clinical success was 94%, and adverse events (bleeding, perforation, stent occlusion, and stent migration) occurred in 28% of patients. Subgroup analysis compared specific types of PFCs and occurrence of adverse events between each group with no significant difference detected in adverse event or reintervention rates.Conclusion:This multicenter study of various types of PFCs requiring EUS-guided drainage demonstrates that deployment of DPS across cautery-enhanced LAMS at the time of initial drainage does not have a significant effect on clinical outcomes, adverse events, or need for reinterventions.

Efficacy and safety of endoscopic drainage of peripancreatic fluid collections: a retrospective multicenter European study.

Endoscopic ultrasound (EUS)-guided transmural drainage allows treatment of symptomatic peripancreatic fluid collections (PFCs), with lumen-apposing metal stents (LAMS) and double pigtail plastic stents (DPPS) being the 2 most frequently used modalities. Consecutive patients undergoing PFC drainage in 10 European centers were retrospectively retrieved. Technical success (successful deployment), clinical success (satisfactory drainage), rate and type of early adverse events, drainage duration and complications on stent removal were evaluated. A total of 128 patients-92 men (71.9%), age 57.2±11.9 years-underwent drainage, with pancreatic pseudocyst (PC) and walled-off necrosis (WON) in 92 (71.9%) and 36 (28.1%) patients, respectively. LAMS were used in 80 (62.5%) patients and DPPS in 48 (37.5%). Technical success was achieved in 124 (96.9%) of the cases, with no difference regarding either the type of stent (P>0.99) or PFC type (P=0.07). Clinical success was achieved in 119 (93%); PC had a better response than WON (91/92 vs. 28/36, P<0.001), but the type of stent did not affect the clinical success rate (P=0.29). Twenty patients (15.6%) had at least one early complication, with bleeding being the most common (n=7/20, 35%). No difference was detected in complication rate per type of stent (P=0.61) or per PFC type (P=0.1). Drainage duration was significantly longer with DPPS compared to LAMS: 88 (70-112) vs. 35 (29-55.3) days, P<0.001. EUS-guided drainage of PFCs achieves high percentages of technical and clinical success. Drainage using LAMS is of shorter duration, but the complication rate is similar between the 2 modalities.

Endoscopic Ultrasound-Guided Drainage in the Management of Postoperative Pancreatic Fistula After Partial Pancreatectomy.

Postoperative pancreatic fistula (POPF) is the most frequent and harmful complication following pancreatic surgery. Traditional management includes conservative treatment, percutaneous drainage (PD), and reoperation. The objective of the present study was to evaluate the safety and effectiveness of EUS (Endoscopic ultrasound)-guided drainage by using nasocystic tubes combined with single or 2 stents for POPF. Patients who had POPF after surgery and then underwent EUS-guided drainage, from October 2016 to October 2019, were enrolled in this study. Technical success was defined as successful transgastric puncture of the peripancreatic fluid collection (PFC) and deployment of the nasocystic tube and stents. Clinical success was defined as symptomatic improvement and the resolution of the fluid collection on follow-up CT scan. A total of 15 patients received EUS-guided drainage. In 13 patients, a nasocystic tube was placed in the PFC combined with a double-pigtail plastic stent. In the remaining 2 patients, a nasocystic tube and 2 stents each were inserted in place. Technical success was achieved in 15 of 15 patients (100%). Clinical success was achieved in 14 of 15 patients (93.3%). In one case, the stent was blocked on the 10th day after the procedure. The median time between surgery and EUS-guided drainage was 10 (5-32) days. The median time of hospital stay after EUS-guided drainage was 16 (11-48) days. Operation-unrelated death occurred in 1 patient (7%) during follow-up. EUS-guided drainage with a nasocystic tube and double-pigtail stents appears to be safe and technically feasible, and could be an alternative treatment for patients with POPF.

EUS-guided gallbladder drainage and subsequent peroral endoscopic cholecystolithotomy: A tool to reduce chemotherapy discontinuation in neoplastic patients?

Background and AimsEUS-guided gallbladder drainage (EUS-GBD) is emerging as a valuable treatment for acute cholecystitis (AC) in patients unfit for surgery. When lumen-apposing metal stents are used, large-caliber access to the gallbladder allows for subsequent direct peroral endoscopic cholecystoscopy (POEC) and eventual cholecystolithotomy (CL), offering a potentially “curative” solution for frailer patients. The aim of this series was to evaluate the outcome of these procedures in oncologic patients experiencing AC, with a specific focus on chemotherapy continuity.MethodsA prospective registry of all consecutive therapeutic EUS procedures performed in the San Raffaele Institute between December 2020 and April 2021 was searched for EUS-GBD + POEC-CL performed in chemotherapy candidates. Clinical and technical variables were prospectively registered, as were days of chemotherapy delay and postprocedural outcomes.ResultsThree consecutive patients with a diagnosis of a malignancy (2 pancreatic cancers and 1 severe myeloproliferative disease with skeletal lesions) experienced AC and were primarily treated by EUS-GBD. After 4 weeks, they were systematically scheduled for POEC-CL and lumen-apposing metal stent exchange for a double-pigtail plastic stent. All procedures and revisions were successful, with rapid clinical improvement. All gallbladders were cleared of food debris and stones between 3 and 15 mm using grasping forceps, polypectomy snares, Dormia baskets, and mechanical lithotripsy. One mild adverse event without any clinical consequence was registered during POEC-CL. Revisions did not interfere with the chemotherapy schedule. Technical variables (eg, gastric vs duodenal drainage or need for coaxial double-pigtail plastic stent) are discussed.ConclusionsEUS-GBD and subsequent POEC-CL allows a highly effective and minimally invasive solution for AC. These initial experiences promote further evaluation of this approach for all those individuals in whom surgical interventions are undesirable, such as oncologic patients whose prognosis depends on chemotherapy continuity, although further prospective confirmation in this setting should be pursued.

The Role of EUS-Guided Drainage in the Management of Postoperative Fluid Collections after Pancreatobiliary Surgery

Postoperative fluid collection (POFC) is a challenging complication following pancreatobiliary surgery. Traditional treatment with surgical drainage is associated with significant morbidity, while percutaneous drainage is associated with a higher rate of recurrence and the need for repeated interventions. Studies have shown that endoscopic ultrasound (EUS)-guided drainage may offer a promising solution to this problem. There are limited data on the ideal therapeutic protocol for EUS-guided drainage of POFC including the timing for drainage; type, size, and number of stents to use; and the need for endoscopic debridement and irrigation. Current practices extrapolated from the treatment of pancreatic pseudocysts and walled-off necrosis may not be applicable to POFC. There are increasing data to suggest that drainage procedures may be performed within two weeks after surgery. While most authors advocate the use of double pigtail plastic stents (DPPSs), there have been a number of reports on the use of novel lumen-apposing metal stents (LAMSs), although no direct comparisons have been made between the two.

Head-to-head comparison between endoscopic ultrasound guided lumen apposing metal stent and plastic stents for the treatment of pancreatic fluid collections: A systematic review and meta-analysis.

Peripancreatic fluid collections (PFCs) result from acute or chronic pancreatic inflammation that suffers a rupture of its ducts. Currently, there exists three options for drainage or debridement of pancreatic pseudocysts and walled-off necrosis (WON). The traditional procedure is drainage by placing double pigtail plastic stents (DPPS); lumen-apposing metal stent (LAMS) has a biflanged design with a wide lumen that avoids occlusion with necrotic tissue, which is more common with DPPS and reduces the possibility of migration. We performed a systematic review and meta-analyses head-to-head, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published from 2014 to 2020, including only studies that compare the two main techniques to drainage of PFCs: LAMS vs DPPS. Thirteen studies were included in the meta-analyses. Only one of all studies was a randomized controlled trial. These studies comprise 1584 patients; 68.2% were male, and 31.8% were female. Six hundred sixty-three patients (41.9%) were treated with LAMS, and 921 (58.1%) were treated with DPPS. Six studies included only WON in their analysis, two included only pancreatic pseudocysts, and five studies included both pancreatic pseudocysts and WON. The technical success was similar in patients treated with LAMS and DPPS (97.6% vs 97.5%, respectively, P=.986, RR=1.00 [95% CI 0.93-1.08]). The clinical success was similar in both groups (LAMS: 90.1% vs DPPS: 84.2%, P=.139, RR=1.063 [95% CI 0.98-1.15]). Patients treated with LAMS had a lower complication rate than the DPPS groups, with a significant statistical difference (LAMS: 16.0% vs DPPS: 20.2%, P=.009, RR=0.746 [95% CI 0.60-0.93]). Bleeding was the most common complication in the LAMS group (33 patients, [5.0%]), whereas infection was the most common complication in the DPPS group (56 patients, [6.1%]). The LAMS migration rate was lower than in the DPPS (0.9% vs 2.2%, respectively, P=.05). The mortality rate was similar in both groups, 0.6% in the LAMS group (four patients) and 0.4% in the DPPS group (four patients; P=.640). The PFCs drainage is an indication when persistent symptoms or PFCs-related complications exist. EUS guided drainage with LAMS has similar technical and clinical success to DPPS drainage for the management of PFCs. The technical and clinical success rates are high in both groups. However, LAMS drainage has a lower adverse events rate than DPPS drainage. More randomized controlled trials are needed to confirm the real advantage of LAMS drainage over DPPS drainage.

Indwelling double-pigtail plastic stents for treating disconnected pancreatic duct syndrome-associated peripancreatic fluid collections: long-term safety and efficacy.

Long-term transmural double-pigtail stent (DPS) placement is recommended for patients with disconnected pancreatic duct syndrome (DPDS) and peripancreatic fluid collections (peri-PFCs). The long-term safety and efficacy of indwelling DPSs were evaluated. Medical files of patients treated with DPS for DPDS-associated peri-PFC and with a follow-up ≥ 48 months were reviewed. Early ( < 30 days) and late complications of DPS placement were evaluated and the primary endpoint, i. e., incidence of late complications per 100 patient-years of follow-up, was calculated. Short- and long-term success rates of endoscopic treatment and rate of peri-PFC recurrence were among secondary endpoints. From 2002 to 2014 we identified 116 patients, with mean (SD) follow-up of 80.6 (34.4) months. Among early complications (n = 20), 6 occurred peri-interventionally. Late complications (n = 17) were mainly pain due to DPS-induced ulcer or erosion (n = 10) and 14 of these were treated conservatively or by stent removal; 2 gastro-pancreatico-colo-cutaneous fistulas and 1 persisting bleed required surgical intervention. No DPS-related deaths were recorded. The incidence rate (95 %CI) of late complications was 2.18 (1.27-3.49) per 100 patient-years of follow-up. Short- and long-term success rates (with 95 %CI) of endoscopic treatment were 97.4 % (94.5 %-100 %) and 94 % (89.6 %-98.3 %), respectively. The peri-PFC recurrence rate was 28 % (20.1 %-35.9 %), and 92.3 % of these occurred within the first 2 years. Stent migration, chronic pancreatitis, and length of stent (> 6 cm) were independently associated with higher rates of peri-PFC recurrence. Long-term transmural drainage with DPS is a safe and effective treatment for DPDS-associated peri-PFCs. However, about one quarter of peri-PFCs will recur.

Is a coaxial plastic stent within a lumen-apposing metal stent useful for the management of distal malignant biliary obstruction?

There are uncertainties concerning the possible benefits derived from the insertion of double-pigtail plastic stents (DPS) within lumen-apposing metal stents (LAMS) in EUS-guided choledochoduodenostomy (CDS). The aim of this study was to determine whether a DPS within a biliary LAMS offers a potential benefit in EUS-guided CDS for the palliative management of malignant biliary obstruction. This was a multicentre retrospective study at three tertiary institutions. May 2015 to August 2020. Two interventional strategies (LAMS alone and LAMS plus DPS) were compared. The choice was the endoscopist's discretion. Inclusion: unresectable/inoperable biliopancreatic tumours with previous failed ERCP. Clinical success: bilirubin decrease > 30% at 4weeks. Forty-one consecutive cases of EUS-CDS using biliary LAMS were treated (22 women; mean age, 72.3years) during the study period. The procedure was technically successful in 39 (95.1%), who were managed using the two strategies (22 LAMS alone; 17 LAMS plus DPS). No differences between the groups, in terms of clinical success (77.3 vs 87.5%, p = 0.67), adverse events (AEs, 13.6 vs 11.8%, p = 0.99), recurrent biliary obstruction (RBO, 13.6 vs 23.5%, p = 0.67), or survival rate (p = 0.67) were encountered. The LAMS alone group had a shorter length of procedure (50min vs 66min, p = 0.102). No risk factors related to clinical success, AEs, RBO, or survival were detected. The technical variant of adding a coaxial DPS within LAMS in EUS-CDS seems not to be enough to prevent biliary morbidities, and it is a time-consuming strategy. Although prospective studies are needed, these results do not support its routine use.

Efficacy and safety of endoscopic ultrasound-guided drainage of pancreatic pseudocysts using double-pigtail plastic stents: A single tertiary center experience

OBJECTIVES:Pancreatic pseudocysts (PPC) are fluid collections with a well-defined wall that persist for more than 4 weeks inside or around the pancreas as a result of pancreatic inflammation and/or a ductal lesion. PPC have been successfully treated with endoscopic ultrasound (EUS)-guided drainage using different stents. This study aimed to evaluate the safety and efficacy of EUS-guided drainage of PPC using double-pigtail plastic stents in a tertiary hospital.METHODS:Patients with PPC referred for EUS-guided drainage between May 2015 and December 2019 were included in this case series. The primary endpoint was to evaluate the efficacy (clinical success) and safety (adverse events and mortality) of EUS-guided drainage of PPC. Secondary endpoints included technical success and pseudocyst recurrence.RESULTS:Eleven patients (mean age, 44.5±18.98 years) were included in this study. The etiologies for PPC were acute biliary pancreatitis, chronic alcoholic pancreatitis, and blunt abdominal trauma. The mean pseudocyst size was 9.4±2.69 cm. The clinical success rate was 91% (10/11). Adverse events occurred in three of 11 patients (27%). There were no cases of mortality. The technical success rate was 100%. Pseudocyst recurrence was identified in one of 11 patients (9%) at 12 weeks after successful clinical drainage and complete pseudocyst resolution.CONCLUSION:EUS-guided transmural drainage of PPC using double-pigtail plastic stents is safe and effective with high technical and clinical success rates.

Safety and efficacy of lumen-apposing metal stents versus plastic stents to treat walled-off pancreatic necrosis: systematic review and meta-analysis.

Background and study aims Lumen-apposing metal stents (LAMS) are increasingly used for drainage of walled-off pancreatic necrosis (WON). Recent studies suggested greater adverse event (AE) rates with LAMS for WON. We conducted a systematic review and meta-analysis to compare the safety and efficacy of LAMS with double-pigtail plastic stents (DPPS) for endoscopic drainage of WON. The primary aim was to evaluate stent-related AEs. Methods In October 2019, we searched the Ovid (Embase, MEDLINE, Cochrane) and Scopus databases for studies assessing a specific LAMS or DPPS for WON drainage conducted under EUS guidance. Safety outcomes were AE rates of bleeding, stent migration, perforation, and stent occlusion. Efficacy outcomes were WON resolution and number of procedures needed to achieve resolution. A subanalysis including non-EUS-guided cases was performed. Results Thirty studies including one randomized controlled trial (total 1,524 patients) were analyzed. LAMS were associated with similar bleeding (2.5 % vs. 4.6 %, P = 0.39) and perforation risk (0.5 % vs. 1.1 %, P = 0.35) compared to DPPS. WON resolution (87.4 % vs. 87.5 %, P = 0.99), number of procedures to achieve resolution (2.09 vs. 1.88, P = 0.72), stent migration (5.9 % vs. 6.8 %, P = 0.79), and stent occlusion (3.8 % vs. 5.2 %, P = 0.78) were similar for both groups. Inclusion of non-EUS-guided cases led to significantly higher DPPS bleeding and perforation rates. Conclusions LAMS and DPPS were associated with similar rates of AEs and WON resolution when limiting analysis to EUS-guided cases. Higher bleeding rates were seen in historical studies of DPPS without EUS guidance. Additional high-quality studies of WON treatment using consistent outcome definitions are needed.

Cerrahi için yüksek riskli bir hastada akut kolesistitin endoskopik transpapiller drenajı

Akut kolesistit, safra taşlarının sık görülen komplikasyonlarından birisidir. Akut kolesistit için genellikle kolesistektomi önerilir. En sık tercih edilen yöntem laparoskopik kolesistektomidir. Ancak ameliyatın kontrendike olduğu durumlarda endoskopik transpapiller safra kesesi drenajı alternatif bir yöntem olarak kabul edilir. 86 yaşında kadın hasta, acil servise, sağ üst kadran ağrısı ve ateş yüksekliği yakınmalarıyla başvurduğunda çekilen abdomen tomografisinde taşlı kolesistit saptandı. Hasta kolesistit, kolanjit ve biliyer sepsis ön tanılarıyla yatırılarak acil endoskopik retrograd kolanjiyografi yapıldı. Safra kesesine 10 Fr 10 cm double pigtail plastik stent ve sağ ve sol ana safra kanalına uzanacak şeklide iki adet 10 Fr double pigtail stent yerleştirildi. İşlem sonrası klinik takiplerinde hasta hızlıca düzeldi ve post-operatif 1 hafta sonra taburcu edildi. Safra kesesinin endoskopik drenajı, transpapiller yoldan veya transmural yoldan endoskopik ultrasonografi ile yapılabilir. Prosedür teknik olarak başarılı olduğunda, transpapiller drenaj, akut kolesistitli hastaların %90’ından fazlasında etkili tedavi sağlar. Endoskopik drenaj yöntemleri kolesistektomi riski yüksek olan hastalarda teknik olarak uygulanabilir, güvenli ve etkili tekniklerdir.

A novel value-based scoring system for endoscopic ultrasound-guided drainage of pancreatic fluid collections: a single-centre comparative study of plastic and lumen-apposing metal stents (NOVA study)

Healthcare resources are finite. Value in healthcare can be defined as patient health outcomes achieved per monetary unit spent. Attempts have been made to quantify the value of luminal endoscopy, but there is little in the medical literature describing the value of the complex therapeutic endoscopic activity. This study aimed to characterise the value of endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) with either plastic or lumen-apposing metal stents (LAMSs). This is a single-centre, retrospective-prospective comparative study of 39 patients, who underwent EUS-guided PFC drainage between 2009 and 2018. Procedure value was calculated using the formula Q/(T/C), where Q is the quality of procedure adjusted for complications, T procedure duration and C is the complexity adjustment. Quality and complexity were estimated on a 1-4 Likert scale based on the American Society for Gastrointestinal Endoscopy criteria. Time (in minutes) was recorded from the patient entering and leaving the procedure room. Endoscopy time calculated from procedure time was considered a surrogate marker of cost as individual components of procedure cost were not itemized. Of 39 identified patients who underwent EUS-guided PFC drainage, 11 received double pigtail plastic stents (DPPSs) and 28 received LAMSs. The two groups were comparable in age, gender and aetiology. Nearly 40% of the LAMS interventions were considered high value but only 11% of the plastic stent interventions achieved the same. The difference predominantly was due to a higher rate of complications and longer procedure time. In this single-centre study, EUS-guided PFC drainage using LAMS was found to be a higher value procedure compared to the use of DPPS.
