BACKGROUND: This study highlights an unusual and previously unreported adverse event (AE) following the minimally invasive treatment of pancreatic walled-off necrosis (WON). The standard treatment for WON currently involves primary drainage via an ultrasound-guided endoscopic, typically transgastric, approach. This method is associated with lower mortality and morbidity rates compared to traditional surgery. However, emerging AEs from these procedures may necessitate the involvement of a multidisciplinary team. Our case highlights the potential for gastrovesical fistula development as a rare AE following endoscopic drainage. Treatment for our patient prioritized individualized and non-surgical strategy, although surgical revision was also considered. CASE DESCRIPTION: A 42-year-old male presented with a large symptomatic pancreatic WON refractory to conservative management, necessitating transgastric drainage. Despite the gradual evacuation of the WON contents, treatment was complicated by stent-related issues, including inadvertent bladder penetration. Rather than surgical correction, a collaborative approach among urology, gastroenterology, and surgery teams was employed, focusing on conservative treatment strategies. This approach successfully resolved the fistula, leading to the patient's full recovery. CONCLUSIONS: Given the increasing use of endoscopic transluminal drainage in (peri)pancreatic collections, it is crucial to be aware of all potential AEs. To our knowledge, this is the first documented case of gastrovesical fistula following drainage of WON. Early recognition and a multidisciplinary approach are vital to manage this event.

In a subset of patients with acute necrotizing pancreatitis, segmental necrosis affecting the main pancreatic duct may result in a discontinuity between the left-sided pancreas and the duodenum. Such an interruption in the setting of a viable upstream portion of the gland can give rise to the disconnected pancreatic duct syndrome (DPDS). By maintaining its secretory function, the disconnected segment may lead to persistent external pancreatic fistulae, recurrent pancreatic fluid collections, and/or obstructive recurrent acute or chronic pancreatitis of the isolated parenchyma. There are currently no universally accepted guidelines for the diagnosis or treatment of DPDS, and because the condition is underrecognized, the diagnosis is often delayed. DPDS is associated with a prolonged disease course and poses a burden on patients' quality of life as well as high health care resource utilization. The aim of our review is to summarize current knowledge, discuss diagnostic approaches, outline management options, and raise awareness of this challenging complication of necrotizing pancreatitis.

INTRODUCTION: Percutaneous endoscopic cecostomy (PEC) is a viable treatment option for patients with persistent or recurrent acute colonic pseudo-obstruction (ACPO; Ogilvie's syndrome). It should be generally considered in patients that are refractory to pharmacologic and endoscopic decompression, especially those not amenable to surgical intervention due to an increased perioperative risk. Physicians are rather unfamiliar with this approach given the limited number of reports in the literature and paucity of guideline resources, although guidelines concerning ACPO and covering the role of endoscopy were recently published by three major expert societies, all within the last 2 years. PATIENTS AND METHODS: We retrospectively identified three consecutive patients who underwent PEC placement at a Czech tertiary referral center between May 2018 and December 2021: all for recurrent ACPO. In addition, we summarized the current guidelines in order to present the latest knowledge related both to the procedure and management approach in patients with ACPO. RESULTS: The placement of PEC was successful and resulted in clinical improvement in all cases without any adverse events. CONCLUSION: The results of our experience are in line with previous reports and suggest that PEC may become a very useful tool in the armamentarium of modalities utilized to treat ACPO. Furthermore, the availability of guideline resources now offers comprehensive guidance for informed decision-making and the procedural aspects.

Úvod a cíl: Primární diagnostika distálních biliárních striktur může být někdy svízelná a obtížná. Je známo, že kartáčková cytologie (BC – brush cytology) má v těchto případech nízkou diagnostickou senzitivitu. Fluorescenční in situ hybridizace (FISH) byla popsána jako užitečná doplňková metoda u pacientů se strikturami žlučových cest. Cílem naší studie bylo stanovit diagnostickou výtěžnost BC, FISH a jejich kombinace (BC + FISH) v primární diagnostice distálních biliárních striktur. Metodika: Tato prospektivní studie byla provedena v období od dubna 2019 do ledna 2021. Do studie byli postupně zařazeni pacienti s dosud nebioptovanými biliárními strikturami, kteří podstoupili první endoskopickou retrográdní cholangiopankreatografii (ERCP) na našem pracovišti. Byly provedeny cytologické a FISH analýzy vzorků tkáně odebraných ze dvou standardizovaných transpapilárních odběrů „kartáčkem“ z distálních striktur. Postoperační histologie nebo výsledky 12měsíčního sledování pacientů byly považovány za zlatý standard pro stanovení konečné diagnózy. Výsledky: Do studie bylo zařazeno celkem 109 pacientů. Sedm pacientů bylo z konečné analýzy vyřazeno a 26 mělo proximální stenózu. Ze zbývajících 76 pacientů (61,8 % mužů, průměrný věk 67,6 let, rozmezí 25–89 let) s distální stenózou byl podíl benigních a maligních striktur 25 (32,9 %), resp. 51 (67,1 %). Z podskupiny maligních striktur tvořilo 17,7 % cholangiokarcinom, 74,5 % nádory pankreatu a 7,8 % jiné nádory. Ve srovnání se samotnou BC zvýšila FISH senzitivitu z 0,373 % na 0,706 % (p = 0,0007) při mírném poklesu specificity (p = 0,045). Závěr: Duální modalita hodnocení tkáně pomocí BC + FISH má lepší senzitivitu pro primární diagnózu distálních biliárních striktur ve srovnání se samotnou BC.

Background and aim: Primary diagnosis of the distal biliary stricture can be sometime difficult. Brush cytology (BC) is known to have low diagnostic sensitivity in these cases. Fluorescence in situ hybridization (FISH) has been reported as a useful adjunctive test in patients with biliary strictures. We aimed to determine performance characteristics of BC, FISH and their combination (BC + FISH) in the primary diagnosis of distal biliary strictures. Methods: This single-center prospective study was conducted between April 2019 and January 2021. Consecutive patients with unsampled biliary strictures undergoing first ERCP in our institution were included. Cytological and FISH analysis of tissue specimens from two standardized transpapillary brushings from the distal strictures were provided. Histopathological confirmation after surgery or 12-month follow-up was regarded as the reference standard for the final diagnosis. Results: A total of 109 patients were enrolled. Seven patients were lost from the final analysis and 26 suffered proximal stenosis. Of the 76 remaining patients (61.8% males, mean age 67.6, range 25–89 years) with distal stenosis, the proportions of benign and malignant strictures were 25 (32.9%) and 51 (67.1%), respectively. Of the subgroup of malignant strictures, 17.7% were cholangiocarcinoma, 74.5% were pancreatic tumors and 7.8% others. In comparison to BC alone, FISH increased the sensitivity from 0.373% to 0.706% (p = 0.0007) with a slight decrease in specificity (p = 0.045). Conclusions: Dual modality tissue evaluation using BC + FISH has better sensitivity for the primary diagnosis of distal biliary strictures, compared to BC alone.

INTRODUCTION AND PURPOSE: With current imaging modalities and diagnostic tests, identifying pain generators in patients with non-specific chronic low back pain (CLBP) is difficult. There is growing evidence of the effectiveness of SPECT/CT examination in diagnosing the source of pain in the spine. The study aims to investigate the effect of posterior interbody fusion on a single-level SPECT/CT positive lumbar degenerative disc disease (DDD). MATERIAL AND METHODS: This is a prospective study of patients with chronic low back pain (CLBP) operated on for a single-level SPECT/CT positive DDD. Primary outcomes were changes in visual analogue scale (VAS) scores and the Oswestry Disability Index (ODI). Secondary outcomes were complications, return to work, satisfaction and willingness to re-undergo surgery. RESULTS: During a 3-year period, 38 patients underwent single-level fusion surgery. The mean preoperative VAS score of 8.4 (± 1.1) decreased to 3.2 (± 2.5, p < 0.001) and the mean preoperative ODI of 51.5 (± 7.3) improved to 20.7 (± 14.68, p < 0.001) at a 2-year follow-up. A minimum clinically important difference (30% reduction in VAS and ODI) was achieved in 84.2% of patients. Some 71% of patients were satisfied with the surgery results and 89.4% would undergo surgery again. There were four complications, and two patients underwent revision surgery. Some 82.9% of patients returned to work. CONCLUSION: Fusion for one-level SPECT/CT positive lumbar DDD resulted in substantial clinical improvement and satisfaction with surgical treatment. Therefore, SPECT/CT imaging could be useful in assessing patients with CLBP, especially those with unclear MRI findings. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04876586.

Background and aims: Diagnosis of the biliary stricture remains a challenge. In view of the low sensitivity of brush cytology (BC), fluorescence in situ hybridization (FISH) has been reported as a useful adjunctive test in patients with biliary strictures. We aimed to determine performance characteristics of BC and FISH individually and in combination (BC + FISH) in the primary diagnosis of biliary strictures. Methods: This single-center prospective study was conducted between April 2019 and January 2021. Consecutive patients with unsampled biliary strictures undergoing first endoscopic retrograde cholangiopancreatography in our institution were included. Tissue specimens from two standardized transpapillary brushings from the strictures were examined by routine cytology and FISH. Histopathological confirmation after surgery or 12-month follow-up was regarded as the reference standard for final diagnosis. Results: Of 109 enrolled patients, six were excluded and one lost from the final analysis. In the remaining 102 patients (60.8% males, mean age 67.4, range 25-92 years), the proportions of benign and malignant strictures were 28 (27.5%) and 74 (72.5%), respectively. The proportions of proximal and distal strictures were 26 (25.5%) and 76 (74.5%), respectively. In comparison to BC alone, FISH increased the sensitivity from 36.1% to 50.7% (p = 0.076) while maintaining similar specificity (p = 0.311). Conclusions: Dual-modality tissue evaluation using BC + FISH showed an improving trend in sensitivity for the primary diagnosis of biliary strictures when compared with BC alone.

Úvod: Neurinomy jsou skupinou dobře diferencovaných benigních tumorů vycházejících ze Schwannových buněk periferních nervů. Jejich výskyt v oblasti pánve je vzácný. Expandující neurinomy se mohou projevovat pestrou neurologickou symptomatologií nebo útlakem orgánů pánve. Kazuistika: Autoři prezentují případ 60leté pacientky s objemným symptomatickým hluboce uloženým neurinomem pánve. Nemocná podstoupila roboticky asistovanou operaci s kompletní exstirpací tumoru. Pooperační průběh byl nekomplikovaný s dimisí druhý pooperační den. Histologicky byla potvrzena diagnóza neurinomu. Pacientka je 11 měsíců od operace bez obtíží a bez neurologického deficitu. Závěr: Roboticky asistovaná operace umožňuje bezpečnou a efektivní chirurgickou léčbu ve špatně přístupných anatomických prostorech. Magnetická rezonance je obligatorní metodou při předoperačním zobrazení neurogenních nádorů. V případě průkazu neurinomu není histologická verifikace doporučována. Nutná je multidisciplinární spolupráce s dedikovaným týmem se zkušeností s miniinvazivní pánevní chirurgií.

Introduction: Schwannomas are a group of well differentiated benign tumors originating from the Schwann cells of the peripheral nervous system. Their localization in the pelvis is very rare. Schwannomas with expansive growth can cause wide neurologic symptoms or oppression of pelvic organs. Case report: The authors present a case study of a 60-year-old woman with a large, symptomatic deep pelvic schwannoma. The patient underwent robotic-assisted surgery resulting in complete tumor extirpation. The patient’s postoperative course was uneventful with a total of two hospitalization days. The diagnosis of a schwannoma was confirmed by histopathologic analysis. At 11-month follow-up surveillance the patient did not present any neurological deficit or other symptoms. Conclusion: Robotic-assisted surgery allows safe and effective surgical treatment in difficult-to-access anatomical areas. Magnetic resonance imaging is required for preoperative imaging of neurogenic tumors. Histological verification is not recommended in cases where evidence of a schwannoma is found. Multidisciplinary cooperation of a dedicated team experienced in minimally invasive pelvic surgery is necessary.

BACKGROUND AND AIMS: Lumen-apposing metal stents (LAMSs) have proven to be effective for drainage of pancreatic walled-off necrosis (WON), although associated adverse events (AEs) have been reported. Anchoring coaxial double-pigtail plastic stents (DPSs) within LAMSs have been proposed to prevent LAMS-related AEs but have not been assessed in prospective studies. We aimed to evaluate the utility of such measures with a randomized controlled trial. METHODS: We randomly assigned consecutive patients with WON indications for drainage to EUS-guided transluminal drainage using LAMSs with (group A) or without (group B) DPSs. All LAMSs were to be removed after 3 weeks had elapsed from the index procedure with a preceding CT to decide whether additional steps needed to be taken (eg, transluminal necrosectomy or placing transluminal plastic stents in patients with incomplete resolution of WON). The main outcomes were failure of the index method, defined as necessity of reintervention (endoscopic, percutaneous, or surgical) before LAMS removal because of LAMS-related AEs and/or clinical deterioration; AE rates; and mortality with the LAMS in place. Variables were evaluated using the Mann-Whitney U test, χ2 test, or Fisher exact test as appropriate. P < .05 was considered significant. RESULTS: Sixty-seven patients (37.3% women; mean age, 54 ± 14.4 years) underwent LAMS placement with (n = 34) or without (n = 33) DPS placement in 2 tertiary centers. Baseline characteristics including demographics, etiology, comorbidity, and clinical presentation (sterile vs infected necrosis) were comparable between both groups. The technical success rate in placing LAMSs and DPSs was 100%. The global rate of AEs was significantly lower in group A versus group B (20.7% vs 51.5%, respectively; P = .008). Stent occlusion was the most frequently observed AE (14.7% vs 36.3%, P = .042). Failure of the index method was lower in group A versus group B (29.4% vs 48.5%, respectively; P = .109); however, the difference did not achieve statistical significance. The same applied to the mortality rate with LAMSs in place (2.9% vs 12.1%, P = .197). CONCLUSIONS: The addition of a coaxial DPS within a LAMS was associated with a significantly lower global rate of AEs and stent occlusion rate in EUS-guided drainage of WON.
