Medical therapy has similar hemostatic efficacy with endoscopic treatment for PUB patients with adherent clot (FIIb ulcers)

BACKGROUND

Currently, there is no clear consensus on whether medical treatment or endoscopic treatment should be used for peptic ulcer bleeding patients with adherent clot. The aim of this study is to investigate the hemostatic effects of medical treatment, single endoscopic treatment, and combination endoscopic treatment for peptic ulcer bleeding (PUB) patients with adherent clot.

METHODS

We retrospectively analyzed PUB patients with adherent clot who underwent endoscopic examination or treatment in our center from March 2014 to January 2023 and received intravenous administration of proton pump inhibitors. Patients were divided into medical treatment (MT) group, single endoscopic treatment (ST) group, and combined endoscopic treatment (CT) group. Subsequently, inverse probability of treatment weighting (IPTW) was performed to calculate the rebleeding rate.

RESULTS

A total of 605 eligible patients were included in this study. After IPTW, the rebleeding rate in the MT group on days 3, 7, 14, and 30 were 13.3 (7.3), 14.2 (7.8), 14.5 (7.9), and 14.5 (7.9), respectively; the rebleeding rates in the ST group were 17.4 (5.1), 20.8 (6.1), 20.8 (6.1), and 20.8 (6.1), respectively; the rebleeding rates in the CT group were 0.4 (0.9), 1.7 (3.3), 2.3 (4.5), and 2.3 (4.5), respectively. Although the rebleeding rate in the medical treatment group was higher, there was no significant difference among the three groups on days 3, 7, 14, and 30 (P = 0.132, 0.442, 0.552, and 0.552).

CONCLUSIONS

Medical therapy has similar hemostatic efficacy with endoscopic treatment for PUB patients with adherent clot (FIIb ulcers). However, for patients with more risk factors and access to well-equipped endoscopy centers, endoscopic treatment may be considered. The choice of treatment approach should be based on the individual conditions of the patient, as well as other factors such as medical resources available.

The correlation between ureteric orifice morphology and primary vesicoureteral reflux grade and the impact on the effectiveness of endoscopic reflux correction

INTRODUCTION

Early diagnosis and treatment of primary vesicoureteral reflux (VUR) are essential for preserving renal function.

OBJECTIVES

The study explored whether preoperative cystoscopic grading of refluxing ureteric orifices (UO) correlated with their shape in an institution with non-performance of hydrodistention of the UO in the diagnosis and grading of VUR. We also assessed the relationship between the UO shape and VUR grade with the effectiveness of endoscopic correction of primary VUR in children.

METHODS

This retrospective study included consecutive patients ≤15 years treated for primary VUR. The reflux grade was based on the results of preoperative voiding cystourethrography as mild, moderate, or severe.

RESULTS

Fifty-one patients with 77 renal refluxing units (RRU) underwent endoscopic treatment with Deflux®. VUR was bilateral in 51 % of patients. VUR was mild in 13 %, moderate in 53 %, and severe in 34 % of cases. The patients with mild and moderate VUR had stadium-shaped UOs in 60 % and 54 % RRUs, respectively. Horseshoe-shaped UOs constituted 42 % of UOs in patients with severe VUR, followed by 31 % of golf-hole UOs. The reflux resolution rate after the first endoscopic injection was 84 %. The preoperative VUR grade correlated with UOs shape (p < 0.001). No significant correlation between UOs configuration and the outcome of endoscopic treatment was seen (p = 0.452). The preoperative VUR grade negatively correlated with a favorable endoscopic treatment (p = 0.043).

DISCUSSION AND CONCLUSION

Our data indicate ureteral orifice shapes are closely related to preoperative VUR grade. There was no correlation between the UO configuration and the success rate of endoscopic treatment of VUR, in contrast to the significant negative correlation between the VUR grade and the success rate of endoscopic treatment.

Current interventional options for palliative care for patients with advanced-stage cholangiocarcinoma

Primary biliary tract tumors are malignancies that originate in the liver, bile ducts, or gallbladder. These tumors often present with jaundice of unknown etiology, leading to delayed diagnosis and advanced disease. Currently, several palliative treatment options are available for primary biliary tract tumors. They include percutaneous transhepatic biliary drainage (PTBD), biliary stenting, and surgical interventions such as biliary diversion. Systemic therapy is also commonly used for the palliative treatment of primary biliary tract tumors. It involves the administration of chemotherapy drugs, such as gemcitabine and cisplatin, which have shown promising results in improving overall survival in patients with advanced biliary tract tumors. PTBD is another palliative treatment option for patients with unresectable or inoperable malignant biliary obstruction. Biliary stenting can also be used as a palliative treatment option to alleviate symptoms in patients with unresectable or inoperable malignant biliary obstruction. Surgical interventions, such as biliary diversion, have traditionally been used as palliative options for primary biliary tract tumors. However, biliary diversion only provides temporary relief and does not remove the tumor. Primary biliary tract tumors often present in advanced stages, making palliative treatment the primary option for improving the quality of life of patients.

Predictors in the treatment of malignant central airway obstruction with silicone stents

PURPOSE

To examine the role of the silicone stent in palliation of malignant central airway obstruction and identify potential preprocedural predictors for postprocedural outcome.

METHODS

Patients treated with endoscopic insertion of tracheobronchial silicone stents for malignant central airway obstruction at Aarhus University Hospital from 2012 to 2022 were identified from electronic medical records. Statistical analyses were carried out to identify factors affecting Days Alive and Out of Hospital, complications and overall survival.

RESULTS

81 patients underwent a total of 90 tracheobronchial stent insertions. Days Alive and Out of Hospital (DAOH) for the first 30 days were affected negatively by urgent intervention, p < 0.001, preprocedural non-invasive respiratory support, p < 0.001, and preprocedural intubation, p = 0.02. Post-procedural oncological treatment was associated with a significant improved DAOH, p = 0.04. Symptomatology and lesion characteristics were not significantly associated with any impact on DAOH. Overall survival was poor (mean survival was 158 days), and only significantly affected by severe degree of dyspnea, p = 0.02, and postprocedural oncological treatment, p < 0.001. Complication where registered in 25.6% of cases within the first 30 days was observed. Procedure-related mortality was 3.7%. Based on chart annotations by an ENT-surgeon, 95% of the patients experienced relief of symptoms following stent insertion.

CONCLUSIONS

Palliative tracheobronchial airway stenting with silicone stents is found to have a beneficial impact, more research is required for identification of predictors for postprocedural outcome based on preprocedural classifications.

Conservative management of an early abdominal complication during a Tullio percutaneous endoscopic excision of renal pelvis urothelial carcinoma: A case report

BACKGROUND

Upper tract urothelial carcinoma (UTUC) representing only a small fraction of all urothelial tumors. It predominantly affects the renal pelvis in men, often coexisting with bladder carcinoma. UTUC displays a more aggressive genetic profile compared to bladder neoplasms, with the majority of patients presenting with advanced disease. Histologically, about a quarter of UTUC cases exhibit high-grade subtypes, associated with a worse prognosis. Tobacco use and past exposure to aromatic amines are significant risk factors for UTUC. Imaging modalities such as Uro-computed tomography and magnetic resonance imaging play crucial roles in diagnosis. Ureterorenoscopy is vital for direct visualization and biopsy sampling, but its limited sampling capacity presents challenges in determining tumor depth and staging. Traditionally, nephroureterectomy with bladder cuff excision has been the gold-standard treatment for UTUC. Endoscopic conservative treatment has recently emerged as a viable option for selected patients, offering comparable oncological outcomes to radical surgery. Percutaneous access is also feasible for larger intrarenal tumors.

CASE SUMMARY

We present a case of an 84-year-old woman who underwent percutaneous endoscopic excision of a renal pelvis neoplasm using the Tullio laser. Despite successful tumor removal, the patient experienced a postoperative complication with abdominal fluid leakage. Conservative management effectively resolved the complication. Given the patient's age and refusal for radical surgery, the conservative approach proved to be a valid therapeutic choice.

CONCLUSION

Overall, UTUC remains a diagnostic and therapeutic challenge due to its rarity. However, advances in endoscopic and percutaneous techniques provide valuable alternatives for selected patients, warranting further exploration in this evolving field.

Current Evidence on Utility, Outcomes, and Limitations of Endoscopic Laser Ablation for Localized Upper Urinary Tract Urothelial Carcinoma: Results from a Scoping Review

Context

The occurrence of upper urinary tract urothelial carcinoma (UTUC) is uncommon and is usually identified at an advanced and multifocal stage. Currently, there is growing interest in utilizing endoscopic laser ablation (ELA).

Objective

To evaluate the survival rates and perioperative complications of ELA.

Evidence acquisition

We performed a literature search through PubMed, Web of Science, and Scopus. The analysis included observational studies that examined the oncological outcomes of patients with UTUC treated with ELA.

Evidence synthesis

Neodymium and diode lasers are no longer used due to their high complication rates. Holmium:yttrium-aluminum-garnet (YAG) and thulium:YAG lasers provided excellent tumor ablation and hemostasis in both the collecting system and the ureter. These lasers offer good disease-free and cancer-specific survival, especially for low-grade tumors.

Conclusions

Advancements in laser technology and ablation techniques, and understanding of UTUC tumor biology hold significant promise in improving the use of conservative UTUC treatment, with excellent safety and good oncological outcomes for low-grade diseases.

Patient summary

With the advancement of technology, the conservative approach utilizing endoscopic laser ablation for upper tract urothelial tumors has been proved to be both safe and effective, showcasing promising survival rates.

Long-term follow-up of a cohort with post sleeve gastrectomy leaks: results of endoscopic treatment and salvage surgery

INTRODUCTION

Laparoscopic sleeve gastrectomy (LSG) is the most performed bariatric procedure worldwide. The most challenging postoperative complication is gastric leak. The objectives of this study are to examine the efficacy and morbidity of different therapeutic strategies addressing leakage, and the long-term outcomes of a cohort of LSG leaks.

METHODS

A retrospective review of patients treated for LSG leaks between September 2014 and January 2023 at our high-volume bariatric surgery center was performed.

RESULTS

The charts of 37 patients (29 women and 8 men) were reviewed, with a mean age of 43 years and a median follow-up of 24 months. The mean preoperative body mass index was 45.1 kg/m2. Overall, 30/37 (81%) patients were successfully treated with endoscopic management, and 7/37 (19%) ultimately underwent salvage surgery. If the leak was diagnosed earlier than 6 weeks, endoscopic treatment had a 97% success rate. The median number of endoscopic procedures was 2 per patient, and included internal pigtails, stents, septoplasty, endoluminal vacuum therapy and over-the-scope clips. Complications included stent-related ulcers (10), esophageal stenosis requiring endoscopic dilatations (4), stent migrations (2) and kinking requiring repositioning (1), and internal pigtail migration (3). Revisional surgery consisted of proximal gastrectomy and Roux-en-Y esophago-jejunal anastomosis, Roux-en-Y fistulo-jejunostomy or classic Roux-en-Y gastric bypass proximal to the gastric stricture. In 62% of the cases, the axis/caliber of the LSG was abnormal. Beyond 4 attempts, endoscopy was unsuccessful. The success rate of endoscopic management dropped to 25% when treatment was initiated more than 45 days after the index surgery.

CONCLUSIONS

Purely endoscopic management was successful in 81% of cases; with 97% success rate if diagnosis earlier than 6 weeks. After four failed endoscopic procedures, a surgical approach should be considered. Delayed diagnosis appears to be a significant risk factor for failure of endoscopic treatment.

The use of fully covered self-expandable metal stents in the endoscopic treatment of portal cavernoma cholangiopathy

BACKGROUND AND AIMS

There are different therapeutic approaches for biliary strictures and reducing portal hypertension in patients with symptomatic portal cavernoma cholangiopathy (PCC). Endoscopic treatment includes endoscopic biliary sphincterotomy (EST), dilation of stricture with a biliary balloon, placement of plastic stent(s) and stone extraction. Fully covered self-expandable metal stent (FCSEMS) is placed as a rescuer in case of haemobilia seen after EST, dilation of stricture and removal of plastic stent rather than the stricture treatment itself. In this retrospective observational study, we sought to assess the clinical outcomes of FCSEMS as the initial treatment for PCC-related biliary strictures.

MATERIALS AND METHODS

Twelve symptomatic patients with PCC both clinically and radiologically between July 2009 and February 2019 were examined. Magnetic resonance cholangiopancreatography (MRCP) and cholangiography were employed as the diagnostic imaging methods. Chandra-Sarin classification was used to distinguish between biliary abnormalities in terms of localization. Llop classification was used to group biliary abnormalities associated with PCC. Endoscopic partial sphincterotomy was performed in all the patients. If patients with dominant strictures 6-8-mm balloon dilation was first performed. This was followed by removal of the stones if exist. Finally, FCSEMS placed. The stents were removed 6-12 weeks later.

RESULTS

The mean age of the patients was 40.9 ± 10.3 years, and 91.6% of the patients were male. Majority of the patients (n = 9) were noncirrhotic. Endoscopic retrograde cholangiopancreatography (ERCP) findings showed that 11 of the 12 patients were Chandra Type I and one was Chandra Type IIIa. All the 12 patients were Llop Grade 3. All patients had biliary involvement in the form of strictures. Stent placement was successful in all patients. FCSEMSs were retained for a median period of 45 days (30-60). Seven (58.3%) patients developed acute cholecystitis. There was no occurrence of bleeding or other complications associated with FCSEMS replacement or removal. All patients were asymptomatic during median 3 years (1-10) follow up period.

CONCLUSIONS

FCSEMS placement is an effective method in biliary strictures in case of PCC. Acute cholecystitis is encountered frequently after FCSEMS, but majority of patients respond to the medical treatment. Patients should be followed in terms of the relapse of biliary strictures.

Feasibility and Safety of Endoscopic Control for Patients with Serrated Polyposis Syndrome

INTRODUCTION

Despite advances in endoscopic treatment, patients with serrated polyposis syndrome (SPS) occasionally require surgery due to numerous or unresectable polyps, recurrence, and treatment-related adverse events.

METHODS

We retrospectively evaluated 43 patients with SPS undergoing diagnosis and treatment at Omori Red Cross Hospital from 2011 to 2022. Resection of all polyps ≥3 mm in size was planned during the clearing phase; endoscopic control was defined as complete, endoscopic polyp removal. During the surveillance phase, patients underwent annual colonoscopy and resection of newly detected polyps ≥3 mm in size.

RESULTS

Thirty-eight patients (88%) achieved endoscopic control, two (5%) required surgery after endoscopic treatment because of colorectal cancer (CRC), and three (7%) have not yet achieved endoscopic control and are planning treatment. Endoscopic control was achieved with a median of four colonoscopies at 8 months. Ten polyps (median value) were resected per patient during the clearing phase. Three polyps ≥50 mm in size, six located in the appendiceal orifice, and seven with severe fibrosis could be resected by endoscopic submucosal dissection (ESD). All patients underwent treatment with a combination of cold snare polypectomy (CSP), endoscopic mucosal resection/hot polypectomy, and/or ESD. No case required surgery due to difficulty with endoscopic treatment. Delayed bleeding was observed in 2 cases (0.3%). Twenty-one patients underwent colonoscopies during the surveillance phase. Fifty-three polyps were resected using CSP; no CRC, sessile serrated lesions with dysplasia, or advanced adenoma were detected.

CONCLUSION

SPS can be effectively, efficiently, and safely controlled with appropriate endoscopic management.

Associations of ureteroceles location and system anatomy with outcomes of endoscopic treatment: A systematic review and meta-analysis

INTRODUCTION

Ureteroceles are a congenital abnormality of the ureter that can cause significant complications. Endoscopic treatment is a commonly used treatment approach. The aim of this review is to assess the results of endoscopic treatment for ureteroceles with consideration to their location and system anatomy.

METHODS

A meta-analysis was conducted by searching electronic databases for studies comparing outcomes of endoscopic treatment for ureteroceles. Newcastle-Ottawa Scale (NOS) was employed to evaluate the potential for bias. The primary outcome was the rate of secondary procedures required following endoscopic treatment. Secondary outcomes were inadequate drainage and post-operative vesicoureteral reflux (VUR) rates. A subgroup analysis was performed to investigate possible causes of heterogeneity in the primary outcome. The statistical analysis was conducted using Review Manager 5.4.

RESULTS

There were 28 retrospective observational studies, published between 1993 and 2022, including 1044 patients with primary outcomes in this meta-analysis. The quantitative synthesis showed that ectopic and duplex system ureteroceles were significantly associated with higher rate of secondary operation compared to intravesical and single system ureteroceles, respectively (OR: 5.42, 95% CI: 3.93-7.47; and OR: 5.10, 95% CI: 3.31-7.87). The associations were still significant in subgroup analysis based on follow up duration, average age at surgery, and duplex system only. For secondary outcomes, incidence of inadequate drainage were significantly higher in ectopic (OR: 2,01, 95% CI: 1.18-3.43), but not in duplex system ureteroceles (OR: 1.94, 95% CI: 0,97-3.86). Post-operative VUR rates were higher in both ectopic (OR: 1.79, 95% CI: 1.29-2.47) and duplex system ureteroceles group (OR: 1.88, 95% CI: 1.15-3.08).

CONCLUSION

Ectopic ureteroceles and duplex system ureteroceles were associated with worse outcomes following endoscopic treatment compared to intravesical and single system ureteroceles, respectively. It is recommended to carefully select patients, conduct pre-operative evaluations, and closely monitor patients with ectopic and duplex system ureteroceles.

Efficacy analysis of endoscopic treatment of giant gastric gastrointestinal stromal tumors (≥5 cm)

OBJECTIVE

To investigate the safety, feasibility and prognosis of endoscopic treatment of giant (≥5 cm) gastric gastrointestinal stromal tumors (gastric GISTs).

METHODS

Data from patients who underwent surgical resection of nonmetastatic gastric GISTs in our hospital from January 2016 to February 2022 were collected. The patients were divided into an endoscopic group and a laparoscopic group according to the surgical method. The clinical data and tumor recurrence information were compared between the two groups.

RESULTS

Eighteen cases were collected in the endoscopic group and sixty-three cases in the laparoscopic group. There were no significant differences in age, gender, tumor diameter, tumor growth site, tumor growth mode, clinical manifestations, risk classification or complication rate between the two groups (P > 0.05). The hospitalization cost, length of postoperative hospital stay and postoperative fasting time of the endoscopic group were less than those of the laparoscopic group, while the operation time was greater than that of the laparoscopic group (P < 0.05). In the endoscopic group, the follow-up was 33.50 ± 19.410 months, and no patients were lost to follow-up. The laparoscopic group was followed up for 59.07 ± 12.964 months, and eleven patients were lost to follow-up. There was no recurrence or metastasis in the two groups during the follow-up.

CONCLUSION

Endoscopic resection of gastric GIST with a diameter ≥5 cm is technically feasible. And it not only achieves a short-term prognosis similar to laparoscopic resection but also has the advantages of rapid postoperative recovery and low cost.

Long-term outcome of randomized clinical trial between polyacrylate-polyalcohol copolymer (PPC) and dextranomer-hyaluronic acid copolymer (Dx/HA) as bulking agents for endoscopic treatment of primary vesicoureteral reflux (VUR)

OBJECTIVE

The aim of our study is to compare long-term outcome of endoscopic treatment of VUR using PPC or Dx/HA.

PATIENTS AND METHODS

From October 2014 to April 2017 patients with VUR grades from 3 to 5 that needed endoscopic treatment were eligible for this RCT. Patients were randomized in two groups: PPC and Dx/HA. A VCUG was performed at 6 months; if VUR > 3 was still present a second ET was performed. We included for this long-term follow-up study those patients that were successfully treated at short-term follow-up. At 36 months postoperative VCUG was performed to assess outcome. Success was considered if postoperative VUR grade was 0 at 36 months, and there was no ureteral obstruction.

RESULTS

In the previous study, 60/73 ureters were successfully treated in 36/44 patients, and then we have analyzed 60 ureters in 36 patients. Three patients were lost in long-term follow-up, and then we analyzed 57 ureters in 33 patients divided. PPC group 18 patients (28 ureters); and Dx/HA group 15 patients (29 ureters). After 3 years of follow-up the VCUG showed a success rate of 26/28 of RU in PPC and 26/29 of DX/HA. Two RU in PPC group had ureteral obstruction, and then the successful rate for PPC group dropped to 24/28. The overall successful rate at long-term was 72.7% of the RU in PPC group and 70.3% in Dx/HA group.

CONCLUSION

PPC and Dx/HA has similar long-term outcome in VUR resolution, but ureteral obstruction could be present at long-term follow-up in PPC group.

Evidence-based clinical practice guidelines for cholelithiasis 2021

The Japanese Society of Gastroenterology first published evidence-based clinical practice guidelines for cholelithiasis in 2010, followed by a revision in 2016. Currently, the revised third edition was published to reflect recent evidence on the diagnosis, treatment, and prognosis of cholelithiasis conforming to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Following this revision, the present English version of the guidelines was updated and published herein. The clinical questions (CQ) in the previous version were reviewed and rearranged into three newly divided categories: background questions (BQ) dealing with basic background knowledge, CQ, and future research questions (FRQ), which refer to issues that require further accumulation of evidence. Finally, 52 questions (29 BQs, 19 CQs, and 4 FRQs) were adopted to cover the epidemiology, pathogenesis, diagnosis, treatment, complications, and prognosis. Based on a literature search using MEDLINE, Cochrane Library, and Igaku Chuo Zasshi databases for the period between 1983 and August 2019, along with a manual search of new information reported over the past 5 years, the level of evidence was evaluated for each CQ. The strengths of recommendations were determined using the Delphi method by the committee members considering the body of evidence, including benefits and harms, patient preference, and cost-benefit balance. A comprehensive flowchart was prepared for the diagnosis and treatment of gallbladder stones, common bile duct stones, and intrahepatic stones, respectively. The current revised guidelines are expected to be of great assistance to gastroenterologists and general physicians in making decisions on contemporary clinical management for cholelithiasis patients.

The effect of endoscopic ultrasound on the precise selection of endoscopic treatment for submucosal tumors in the upper gastrointestinal tract

OBJECTIVE

To summarize and discuss the guiding role of endoscopic ultrasound (EUS) in selecting endoscopic treatments for submucosal tumors (SMTs) in the upper gastrointestinal tract.

METHODS

A retrospective investigation was conducted on 156 SMT patients who received endoscopic resection guided by EUS in the endoscopy center of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine from May 2019 to September 2021. Next, the size, pathological type, and distribution of lesions were analyzed; the correlation of the tumor origin with distribution of lesions and selection of treatments was explored; and the consistency of preoperative EUS diagnosis and postoperative pathological diagnosis was summarized and analyzed.

RESULTS

The tumor diameters of the included SMT patients ranged from 0.3 to 4 cm, with a mean diameter of 0.95 cm; the lesions were mostly located in the esophagus, gastric fundus or fundic cardia and gastric body. As for the pathological types, liomyoma was the most common tumor in the esophagus, liomyoma and mesenchymoma were mainly located in the fundic cardia and gastric body, and heterotopic pancreas was mostly discovered in the gastric sinus. Among 38 esophageal SMT patients, some with lesions originating from muscularis mucosa and submucosa under EUS mainly underwent endoscopic submucosal dissection (ESD) and endoscope band ligation (EBL); while others with lesions originated from muscularis propria mainly received submucosal tunneling endoscopic resection (STER). Of 115 gastric SMT patients under EUS, some with lesion origins from the muscularis mucosa and submucosa mainly underwent endoscopic submucosal excavation (ESE), while others from muscularis propria mainly underwent ESE, ESD, and endoscopic full-thickness resection (EFTR). Besides, 3 duodenal SMT patients with lesion origins from submucosa and muscularis propria under EUS were given ESD and ESE, respectively. Additionally, 121 cases showed a consistency between the EUS diagnosis and the postoperative pathological nature, and the consistency rate was 84.6%.

CONCLUSION

Clarifying the origin layer, size, growth pattern, and pathological nature of the lesion through preoperative EUS can guide the precise selection of endoscopic treatments, thereby ensuring a safe, effective, and complete surgical outcomes and reducing complications.

Outcomes of holmium laser enucleation of the prostate (HoLEP) for very large-sized benign prostatic hyperplasia (over 150 mL): open simple prostatectomy is dead

INTRODUCTION

Our study aimed to describe the outcomes of transurethral enucleation of the prostate (HoLEP) for large-sized benign prostatic hyperplasia over 150 mL (bBPH).

METHODS

We conducted a retrospective, descriptive, and analytical study of patients undergoing HoLEP for bBPH. The primary endpoint was the success of the procedure, defined by a mixed criteria: complete endoscopic enucleation of the prostate, absence of blood transfusion or reoperation for bleeding, post-operative improvement of quality of life (assessed by a ≥ 2 points increase at in the 8th question of the IPSS test) and post-operative continence (no pads use) at 3 months.

RESULTS

Eighty-one patients were included with a mean age of 73.9 ± 7.3 and a mean measured prostate volume of 183.3 ± 34.5 cc. The mean operative time was 57.5 ± 29.7 min and the average wet weight of resected tissue removed was 151.8 ± 44.7 g. Mean hospitalization stay was 1.3 ± 0.7 days with a mean post-operative catheterization period of 1.9 ± 0.9 days. The success of the surgery was achieved in 77 patients (95%). Functional improvements were found at 1 and 6 months for Qmax, post-void residual, IPSS and QoL-IPSS. The 30-day complication rate was 9.9%. The average PSA level dropped from 14.8 ± 11.6 ng/mL at baseline to 0.8 ± 0.5 ng/mL at 6 months.

CONCLUSION

HoLEP for bBPH is both safe and efficient. Regarding the benefit/risk balance, it should be highlighted as the gold standard for the management of big BPH.

Endoscopic treatment (endoscopic balloon dilation/self-expandable metal stent) vs surgical resection for the treatment of de novo stenosis in Crohn's disease (ENDOCIR study): an open-label, multicentre, randomized trial

BACKGROUND

Stenosis is one of the most common complications in patients with Crohn's disease (CD). Endoscopic balloon dilation (EBD) is the treatment of choice for a short stenosis adjacent to the anastomosis from previous surgery. Self-expandable metal stents (SEMS) may be a suitable treatment option for longer stenoses. To date, however, there is no scientific evidence as to whether endoscopic (EBD/SEMS) or surgical treatment is the best approach for de novo or primary stenoses that are less than 10 cm in length.

METHODS/DESIGN

Exploratory study as "proof-of-concept", multicentre, open-label, randomized trial of the treatment of de novo stenosis in the CD; endoscopic treatment (EBD/SEMS) vs surgical resection (SR). The type of endoscopic treatment will initially be with EDB; if a therapeutic failure occurs, then a SEMS will be placed. We estimate 2 years of recruitment and 1 year of follow-up for the assessment of quality of life, costs, complications, and clinical recurrence. After the end of the study, patients will be followed up for 3 years to re-evaluate the variables over the long term. Forty patients with de novo stenosis in CD will be recruited from 15 hospitals in Spain and will be randomly assigned to the endoscopic or surgical treatment groups. The primary aim will be the evaluation of the patient quality of life at 1 year follow-up (% of patients with an increase of 30 points in the 32-item Inflammatory Bowel Disease Questionnaire (IBDQ-32). The secondary aim will be evaluation of the clinical recurrence rate, complications, and costs of both treatments at 1-year follow-up.

DISCUSSION

The ENDOCIR trial has been designed to determine whether an endoscopic or surgical approach is therapeutically superior in the treatment of de novo stenosis in CD.

Endoscopic resection and suturing methods for non-ampullary duodenal submucosal tumors: "mini-invasive" treatments that should never be underestimated

OBJECTIVE

To evaluate the effectiveness and safety of endoscopic resection and various suturing methods to treat non-ampullary duodenal submucosal tumors (NAD-SMTs).

DESIGN

We performed a retrospective observational study of patients with NAD-SMTs who underwent endoscopic resection at Zhongshan Hospital, Fudan University, China, between June 2017 and December 2020. Data on patient characteristics, treatments and follow-up results were collected. The association between clinicopathologic characteristics and different suturing methods or adverse events were analyzed.

RESULTS

Of 128 patients analyzed, 26 underwent endoscopic mucosal resection (EMR), 64 underwent endoscopic submucosal excavation (ESE), and 38 underwent endoscopic full-thickness resection (EFTR). EMR and ESR are both appropriate for non-full-thickness lesions, whereas ESE is more appropriate for tumors located in the bulb or descending duodenum. Gastric tube drainage is more strongly recommended after ESE. Satisfactory suturing is also vital endoscopic resection of NAD-SMTs. Metallic clips are often used in EMR or ESE of non-full-thickness lesions. The pathological findings revealed that the full-thickness lesions were predominantly gastrointestinal stromal tumors (GIST), Brunner's tumor or lipoma, and the surgeons usually used purse-string sutures to close the wounds. The operation time was longer for purse-string suture closure than metallic clip closure. Eleven patients had complications. Risk factors for adverse events included large-diameter tumor (≥ 2 cm), location in the descending part of the duodenum, involvement of the fourth layer of the duodenal wall, EFTR, and GIST.

CONCLUSIONS

Endoscopic resection of NAD-SMTs is effective but is associated with a high incidence of complications due to their anatomical peculiarities. Preoperative diagnosis is quite important. Careful selection of treatment and suturing methods are necessary to reduce the risk of adverse effects. Given the increased frequency of severe complications during or following duodenal endoscopic resection, this procedure should be performed by experienced endoscopists.

Endoscopic treatment of diastasis recti: Training method and literature review

INTRODUCTION

Endoscopic treatment of diastasis rectus abdominis offers the possibility of correcting the condition without complete abdominoplasty. The purpose of this study was to develop a training method on fresh cadavers models based on a literature review on this surgery.

MATERIAL AND METHODS

The endoscopic procedure considered involved the insertion of a 10mm suprapubic trocar and of 5mm trocars in each iliac fossae. The muscle suture is done using running barbed suture. The surgery was performed on eight fresh cadavers to estimate the learning curve for this intervention, which was estimated with the CUSUM method. A systematic literature review in the PubMed database was performed, and 20 articles that met the inclusion criteria were analyzed.

RESULTS

The learning curve threshold was reached after 6 operations and can be separated into two phases. The most common complication of this surgery is seroma, it is encountered in 3 to 27% of cases according to the studies. Diastasis recurrence is rare, occurring in less than 2% of cases. In comparison, open surgical treatment of diastasis recti is associated with a higher risk of hematoma, skin necrosis and longer operating times. Recurrence rates are similarly low after open and endoscopic repair. Mesh reinforcement is indicated in cases of diastasis wider than 5cm, diastasis recurrence, severe musculoaponeurotic laxity, or hernia larger than 1cm.

CONCLUSION

The data in the literature indicate that laparoscopic surgery is an efficient and safe approach to correct diastasis of the rectus muscles and can be offered by plastic surgeons to selected patients.

History of endoscopic treatment of vesicoureteral reflux

Since its first clinical application in 1984, the endoscopic subureteral injection of bulking agents has become an alternative to long-term antibiotic prophylaxis and open surgical intervention in the treatment of VUR in children. The 15 min day care endoscopic procedure has gained worldwide popularity in the management of VUR in children. Over the years, multiple studies have demonstrated safety and long-term efficacy of this minimally invasive outpatient procedure. Nowadays almost 90% of the surgical treatment of VUR in Sweden is done by endoscopic procedure. In the current article, our aim was to review how the endoscopic treatment of VUR developed.

Computed tomography imaging features to evaluate the severity of portal hypertension and predict the rebleeding risk after endoscopic treatment in cirrhotic patients with variceal hemorrhage

PURPOSE

To investigate the association of computed tomography (CT) imaging features and severity of portal hypertension (PH) and develop a nomogram to predict high-risk PH in cirrhotic patients with gastroesophageal variceal hemorrhage (GVH).

METHODS

The study retrospectively enrolled 158 cirrhotic patients with a history of endoscopic treatment for GVH. Hepatic vein pressure gradient (HVPG) was measured and the patients were classified into high-risk (HVPG > 16 mmHg) or low-risk (HVPG ≤ 16 mmHg) PH group. Pre-treatment CT features, including cavernous transformation of portal vein (CTPV), hilar periportal space (a distance between right portal vein and posterior edge of segment IV of the liver), and depth of right posterior hepatic notch sign (a sharp indentation in the right medial posterior liver surface), were evaluated. Risk factors associated with high-risk PH were analyzed, and a nomogram based on the imaging features was developed.

RESULTS

High-risk PH group showed a higher rebleeding rate after treatment than that of the low-risk (P = 0.029). Multivariate analysis indicated that larger hilar periportal space (P < 0.001), less frequencies of CTPV (P = 0.044) and deeper right posterior hepatic notch (P < 0.001) were independent risk factors associated with high-risk PH. A nomogram based on the three CT imaging features was established to predict high-risk PH with an excellent discrimination (c-statistic 0.854).

CONCLUSION

The nomogram based on CT features of hilar periportal space, depth of right posterior hepatic notch and CTPV can help to distinguish cirrhotic patients with high-risk PH, who are more vulnerable of variceal rebleeding after endoscopic treatment.

Assessment of the efficacy of Handmade Vacuum-Assisted Sponge Drain for Treatment of Anastomotic leakage after Low Anterior Rectal Resection

Anastomotic leakage is one of the major complications of colorectal surgery, which might lead to reoperation, increased hospital stays, further intervention and mortality. Vacuum-assisted closure by devices such as Endo-SPONGE® produced by (B-Braun Medical B.V.) is currently being used to treat leakage and fistula. In this study, we aimed to assess the handmade vacuum-assisted sponge drain for anastomotic leakage following low anterior resection. This prospective study included 22 patients who had undergone sponge drain placement to treat anastomotic leakage. All patients had anastomotic leaks or defects after left anterior rectal resection (LAR) without ileostomy. They were treated with neo-adjuvant chemotherapy before the surgery and then subjected to rigid recto-sigmoidoscopy for 30 days following the operation. Any sign of leakage, such as perianal and pelvic pain, was immediately identified and followed up with a CT scan and another recto-sigmoidoscopy. Twenty-two patients were enrolled in this study, 12 men (54.5%) and 10 women (47.4%). All patients had received neo-adjuvant chemotherapy with an average follow-up of 22.30 ± 3.81. 75% of patients (15 cases) were successfully treated, and 17 patients (85%) underwent successful ostomy closure. Treatment failed in 5 patients (25%), including three men and two women. This study shows that handmade vacuum-assisted sponge drain is a cost-effective method of anastomotic leakage management with efficacy similar to that of Endo-SPONGE^®.

Prospective Analysis of Versatility and User Satisfaction with a Novel Single-Use Cystoscope with Working Channel

INTRODUCTION

In the present study, a prospective systematic assessment of the clinical utility of the Ambu® aScopeTM 4 Cysto Reverse Deflection with regard to image quality, maneuverability, and navigation in an outpatient and inpatient setting was performed.

MATERIALS AND METHODS

A prospective multicenter study was performed for evaluation of the instrument during routine cystoscopy. We evaluated the clinical performance of the instruments using a standardized user questionnaire in different categories including image quality, treatment success, imaging of all areas of the urinary bladder, quality of navigation, flexibility of the endoscope, and satisfaction with the device. Statistical analyses were performed by SPSS using the Kruskal-Wallis and Wilcoxon-Mann-Whitney tests. A p value of p ≤ 0.05 was defined as statistically significant.

RESULTS

A total of 200 cystoscopies were performed, and the questionnaire response rate was 100%. The image quality was rated as very good in 65.5% (n = 131), good in 30.5% (n = 61), and neutral in 4% (n = 8) of cases. The criteria for poor or very poor were not mentioned. The characteristic "treatment success based on image quality" was also evaluated as very good in 49% (n = 98) and good in 50.5% (n = 101). The analysis revealed a very good or good overall impression of the examiners in all cases. Replacement of the cystoscope was not necessary during any of the examinations. However, in 3 cases, technical difficulties were documented. Further analysis of the data showed that physicians with less professional experience rated the visualization of the urinary bladder (p = 0.007) and the treatment success with regard to image quality significantly worse (p = 0.007).

CONCLUSION

The Ambu® aScope™ 4 Cysto Reverse Deflection shows high satisfaction values among users in clinical routine. In analogy to other studies with flexible endoscopes, urologists with more professional experience show higher satisfaction values than examiners with less training in flexible endoscopy.

Use of lasers in gastrointestinal endoscopy: a review of the literature

Lasers emit highly directional light with consistent wavelengths, and recent studies have demonstrated their successful applications in gastrointestinal endoscopic therapy. Although argon plasma coagulators (APC) became the preferred treatment option due to improved safety profile and lower costs, advancements in laser and optic fiber manufacturing have reignited interest in laser treatment. Different laser wavelengths have distinct features and applications based on their tissue absorption coefficient. Lasers with shorter wavelengths are effectively absorbed by hemoglobin, resulting in a good coagulation effect. Near-infrared lasers have ability to ablate solid tumors, while far-infrared lasers can make precise mucosal incisions without causing peripheral thermal damage. Lasers have proven to be highly applicable to endoscopy devices such as endoscopes, endoscopic ultrasound (EUS), double-balloon enteroscopes (DBE), and endoscopic retrograde cholangiopancreatography (ERCP), making them a potent tool to enhance the effectiveness of endoscopic treatments with minimal adverse events. This review aims to help readers understand the applications and effectiveness of lasers in gastrointestinal endoscopy, with the potential to promote the development and application of laser technology in the medical field.

Endoscopic management of adult subglottic stenosis: an alternative to open surgery

PURPOSE

Various surgical techniques could be used to treat subglottic stenosis (SGS). The aim of this study is to present our experience in endoscopic management of SGS and show the impact of symptoms' evaluation, clinical examination and spirometry in the therapeutic decision.

METHODS

Endoscopic treatment was performed in patients referred for SGS and consisted of CO₂ scar lysis associated with balloon dilation and concomitant steroids' injection for patients with grade II or higher on the mMRC (modified Medical Research Council) dyspnea scale associated with a DI (Dyspnea Index) score higher than 10/40 and objective stenosis equal or higher than grade II. The preoperative DI score, EDI (expiratory disproportion index) and voice parameters were compared to postoperative results. The mean interval between endoscopic procedures (IEP) was calculated and we looked for the evolution of the IEP during repeated procedures.

RESULTS

Nineteen patients were included. 35 dilations were performed. The mean IEP was 86 weeks. There was a significant decrease of the postoperative DI scores by 18.6 points ± 11 (SD). An important difference of 20.1 ± 13.5 (SD) was identified between the pre and postoperative EDI. Minimal changes occured in voice parameters.

CONCLUSIONS

Endoscopic treatment with CO₂ scar lysis associated with balloon dilation and concomitant steroids' injection is a safe, reliable and minimally invasive endoscopic procedure to treat SGS. Decision to treat has to be on an individual basis taking into account subjective symptoms including Dyspnea Index score and objective laryngoscopic findings and spirometry.

Endoscopic treatment in pediatric patients with recurrent and H-type tracheoesophageal fistulas - A systematic review and meta-analysis

OBJECTIVES

Endoscopic treatments for managing recurrent tracheoesophageal fistula (rTEF) and H-type TEF are being utilized lately; however, the preferred technique is yet to be determined. We aimed to systematically review existing publications on endoscopic treatment of rTEF and H-type TEF to analyze their success and complication rates.

METHODS

PRISMA guidelines were followed. MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials were comprehensively searched in accordance to a priori developed protocol, from 1975 until 2020. English, Spanish and German papers were included. Studies were independently screened and analyzed by two reviewers.

RESULTS

84 full texts were assessed for eligibility out of 581 screened studies, of these, 39 studies with 127 patients were eligible for inclusion (115 rTEF and 12 H-type TEF). All included studies were cases reports or case series. Overall success rate was 45% with sealant injection, 87% with de-epithelialization and 80% with sealant injection and de-epithelialization combined. The mean number of required treatments for success was 1.9 (range 1-6). Mixed effect model meta-analysis of case series with n > 1 showed that sealant injection had a significantly lower success rate of 50% (95% CI 1-99%, I² 72%) compared to de-epithelialization 90% (95% CI 72-99%, I² 27%), p = 0.007 and the combination of both techniques 87% (95% CI 68-99%, I² 11%), p = 0.02. Nine patients (7%) had transient respiratory distress. No mortalities reported.

CONCLUSION

Endoscopic treatment for rTEF and H-type fistula is a minimally invasive technique with favorable outcome and considerably less morbidity compared to open surgery, suggesting it as a safe and effective first line treatment option. Repeated endoscopic treatment attempts can be expected to obtain complete closure. De-epithelization techniques with or without combined tissue adhesive injection had significantly better results than sealant injection techniques alone.

Balloon dilatation is superior to CO2 laser excision in the treatment of subglottic stenosis

INTRODUCTION

Endoscopic treatment of subglottic stenosis (SGS) is regarded as a safe procedure with rare complications and less morbidity than open surgery yet related with a high risk of recurrence. The abundance of techniques and adjuvant therapies complicates a comparison of the different surgical approaches. The primary aim of this study was to investigate disease recurrence after CO₂ laser excisions and balloon dilatation in patients with SGS and to identify potential confounding factors.

MATERIALS AND METHODS

In a tertiary referral center, two cohorts of previously undiagnosed patients treated for SGS were retrospectively reviewed and followed for 3 years. The CO₂ laser cohort (CLC) was recruited between 2006 and 2011, and the balloon dilatation cohort (BDC) between 2014 and 2019. Kaplan‒Meier and multivariable Cox regression analyzed time to repeated surgery and estimated hazard ratios (HRs) for different variables.

RESULTS

Nineteen patients were included in the CLC, and 31 in the BDC. The 1-year cumulative recurrence risk was 63.2% for the CLC compared with 12.9% for the BDC (HR 33.0, 95% CI 6.57-166, p < 0.001), and the 3-year recurrence risk was 73.7% for the CLC compared with 51.6% for the BDC (HR 8.02, 95% CI 2.39-26.9, p < 0.001). Recurrence was independently associated with overweight (HR 3.45, 95% CI 1.16-10.19, p = 0.025), obesity (HR 7.11, 95% CI 2.19-23.04, p = 0.001), and younger age at diagnosis (HR 8.18, 95% CI 1.43-46.82, p = 0.018).

CONCLUSION

CO₂ laser treatment is associated with an elevated risk for recurrence of SGS compared with balloon dilatation. Other risk factors include overweight, obesity, and a younger age at diagnosis.

Tranexamic acid may be a useful pharmacotherapy for endoscopically resistant small bowel angiodysplasia

Small bowel angiodysplasia (SBAD) is reported to account for nearly 50% of cases of small bowel bleeding. When SBAD occurs frequently, it is difficult to treat all the angiodysplasias endoscopically, and gastrointestinal bleeding often recurs. Hormone therapy, somatostatin analogs, thalidomide and vascular endothelial growth factor (VEGF)-neutralizing antibodies have been reported to reduce gastrointestinal angiodysplasia (GIAD) bleeding. However, there is no strong evidence to recommend them. Also, there are no guidelines for their use. Hereditary hemorrhagic telangiectasia (HHT) is a hereditary disease caused by abnormalities in VEGF, resulting in multiple GIADs. A treatment guideline has been created for GIAD in HHT, and the use of tranexamic acid, an antifibrinolytic agent, is the first recommendation pharmacotherapy for GIAD with gastrointestinal bleeding that is difficult to treat endoscopically. It has been reported that fibrinolysis is accelerated in GIAD patients who are not HHT, similar to HHT patients. The use of tranexamic acid for gastric antral vascular ectasia in GIAD has been reported to be useful. However, there are very few reports of its use for SBAD. There are concerns with tranexamic acid use regarding the development of thrombosis/embolism, but there are few reports of such side effects. Future clinical trials including tranexamic acid for SBAD are desired.

RHEMITT Score Predicts Rebleed After Capsule Endoscopy: First Validation at a U.S. Tertiary Care Center

BACKGROUND

Patients with obscure gastrointestinal bleeding undergo small bowel capsule endoscopy (SBCE), but often return for recurrent bleeding or anemia. The RHEMITT score evaluates patients based on 7 variables (heart failure, chronic kidney disease, Saurin P1/P2 lesions, major bleeding, incomplete SBCE, smoking status, and endoscopic treatment) and seeks to predict the risk of rebleeding.

AIMS

This study aims to perform an external validation of the RHEMITT score in the United States.

METHODS

SBCEs performed to evaluate anemia or GI bleeding from a tertiary-care center's PillCam database between 1/22/2018 and 7/21/2020 were reviewed. Variables based on the RHEMITT score were collected. The primary outcome was rebleeding, defined as (1) melena or hematochezia or (2) hemoglobin drop of 2 g/dL. Patient were categorized into low, intermediate, and high-risk categories based on RHEMITT score. The accuracy of the RHEMITT score for predicting rebleeding was assessed.

RESULTS

A total of 361 SBCEs were included in the study. Age, indication for SBCE, endoscopic treatment, antiplatelet use, cirrhosis, heart failure, chronic kidney disease, and major bleeding were significantly associated with risk of rebleed (p < 0.05). Each increasing risk category for the RHEMITT score predicted increased probability of this study's primary outcome, rebleeding (p < 0.001). There was a significant association between RHEMITT risk category and rebleeding-free survival (log-rank p < 0.001). An area under the receiver operating characteristic curve for the RHEMITT score was 0.790 (p < 0.001).

CONCLUSION

Our findings validate the RHEMITT score and confirm acceptable performance for predicting rebleeding at a tertiary referral center in the United States.

Stemming the Leak: A Novel Treatment for Gastro-Bronchial Fistula

Laparoscopic sleeve gastrectomy (LSG) is a commonly used procedure in bariatric patients that often has excellent results. Despite its advantages, LSG is burdened by specific intraoperative and postoperative early and late complications. One of the life-threatening complications is gastric fistula, usually treated with a multidisciplinary surgical-endoscopic approach. In case of failure of the latter, alternative nonoperative techniques such as the use of autologous stem cells truly represents an innovative possibility, with only few cases described in literature. Here, we report the case of a 25-year-old man with post-LSG broncho-gastric fistula treated with application of autologous stem cells after the failure of the conventional surgical/endoscopic approach.

Gastrointestinal Bleeding from Dieulafoy's Lesion in the Cecum

Dieulafoy's lesion is a rare cause of gastrointestinal (GI) bleeding comprising approximately 2% of all acute GI bleeds. It is an abnormal submucosal artery that has a tortuous course before protruding through the mucosa and leading to hemorrhage. Dieulafoy's lesions are most commonly located in the upper GI tract within the lesser curvature of the stomach. Lower GI tract Dieulafoy's lesions are remarkably rare. Our case describes an elderly gentleman who presented with fatigue and dyspnea several days prior to experiencing any evidence of GI bleeding. Initial laboratory investigation revealed severe anemia, requiring packed red blood cell transfusion. Endoscopic examination revealed a cecal Dieulafoy's lesion with active spurting of blood. Hemostasis was achieved through local epinephrine injection and hemostatic clipping. Previously reported cases of cecal Dieulafoy's lesions involve variable presentations including hematochezia, melena, or bright red blood per rectum. These lesions can be treated by angiography, surgically, or endoscopically via techniques that include epinephrine or ethanol injection, argon plasma coagulation, heater probe coagulation, hemostatic clips, or band ligation. Dieulafoy's lesions of the lower GI tract should be considered when no clear culprit is discovered, particularly with the concomitant use of antiplatelet agents and anticoagulants.

A systematic review & meta-analysis comparing outcomes of endoscopic treatment of primary vesico ureteric reflux in children with polyacrylate poly alcohol copolymer versus dextranomer hyaluranic acid

BACKGROUND & AIMS

There are conflicting reports on the efficacy of bulking agents for vesico ureteric reflux (VUR). In this meta-analysis we have compared the outcomes of endoscopic treatment with polyacrylate polyalcohol copolymer (PPC) and dextranomer hyaluronic acid (DxHA).

METHODS

A systematic review of publications between 2010 and 2020 was conducted covering databases like PUBMED, MEDLINE etc. for (endoscopic treatment) AND (VUR) AND (PPC OR DxHA) AND (recurrence OR complications). PRISMA guidelines were followed and only comparative studies were included. Outcomes were early success defined as absence of VUR in voiding cystourethrogram at 3-months followup, urinary tract infections (UTI) and occurrence of vesico-ureteric-junction obstruction (VUJO). Risk of bias was analysed with Robvis tool and odds-ratios were compared with Revman-3.0.

RESULTS

Among nine studies (heterogeneity; I 2 69-79%) all cleared the risk of bias assessment. There was no significant difference in high grade VUR (p = 0.94) between PPC (40%) and DxHA (43%). Success rate after single injection was significantly higher (p = 0.0001) at 86% (477/555) for PPC vs 69% (474/685) for DxHA. UTI rate between PPC (12%) and DxHA (14.6%) was not statistically significant (p = 0.54). VUJO rate between PPC (3.9%) and DxHA (0.8%) was also not significantly different (p = 0.47). Significantly lesser volume (p = 0.02) was used for PPC (0.7 ml) compared to DxHA (0.9 ml).

CONCLUSION

Reflux resolution was significantly higher with PPC than DxHA. Postinjection UTI/VUJO incidence was not significantly different between them. Limitation of this meta-analysis was heterogeneity & small number of articles. Further studies should focus on long-term outcomes and cost-effectiveness.

Efficacy and safety of endoscopic pyloric balloon dilation in patients with refractory gastroparesis

BACKGROUND AND AIMS

There has been interest in the use of pyloric therapies for the treatment of refractory gastroparesis. However, data on endoscopic pyloric dilation are scarce. We aimed to assess the efficacy and safety of this procedure in refractory gastroparesis.

METHODS

We performed a retrospective analysis of 47 patients referred for refractory gastroparesis, confirmed by gastric emptying scintigraphy, and treated with endoscopic pyloric through-the-scope balloon dilation. The primary endpoint was the effectiveness of the procedure, evaluated with the Gastric Cardinal Symptom Index (GCSI) at 2 and 6 months.

RESULTS

A clinical response, defined by a 1.0 point decrease in the GCSI score, was observed in 25 patients at 2 months (53%) and in 19 patients at 6 months (40%). The mean GCSI score decreased significantly at 2 and 6 months compared to the preoperative score (3.9 ± 0.87 vs 2.3 ± 1.37 and 3.9 ± 0.87 vs 2.9 ± 1.27, respectively; p < 0.0001). No complication was observed. Nine patients had a delayed relapse at 1 year. A second dilation was performed for eight patients and it was effective in five of them (63%). The mean follow-up time of the patients was 27.0 ± 10.4 months. At 2 years, 15 patients still experienced improvement following this treatment (32%). No predictive factor of clinical response was identified.

CONCLUSION

The efficacy of pyloric dilation is 53% at 2 months, with sustained improvement in one third of patients at 2 years. This treatment should be considered as an alternative option to pyloromyotomy.

Endoscopic Stenting for Inflammatory Bowel Disease Strictures

Strictures are among the most frequent complications in patients with Crohn's disease (CD), usually requiring a combined medical, surgical, and/or endoscopic approach to treatment. Currently, endoscopic balloon dilation (EBD) is the endoscopic treatment of choice, but its effectiveness is not universal, especially in the long term, and it is not free of complications. The technological evolution of stents in recent years has allowed their use in benign diseases of any origin and location, including inflammatory bowel disease (IBD). The current scientific evidence regarding the use of stents in strictures in IBD is limited and it should not be considered the first option in endoscopic treatment. Self-expandable metal stents (SEMS), but no biodegradable stents (BS), can work in cases that are refractory to anterior endoscopic treatment with EBD, in cases in which EBD is not possible, and in cases with strictures of greater length.

Usefulness of intraoperative voiding cystourethrogram as an indicator of success in the endoscopic treatment of vesicoureteral reflux

OBJECTIVE

Up until now, serial voiding cystourethrogram (SVCU) has been regarded as the gold standard technique in the diagnosis of vesicoureteral reflux (VUR). The aim of intraoperative SVCU during endoscopic treatment is to detect those patients eligible to receive more biosynthetic material as a result of persistent VUR. The objective of this study was to assess the usefulness of SVCU as a predictor of treatment success.

MATERIALS AND METHODS

An analytical, retrospective study of patient medical records was carried out. Patients included had undergone endoscopic VUR surgery from 2000 to 2019, and they were measured in ureteral units. VUR persistence at intraoperative SVCU following treatment was compared with SVCU results after 3 months.

RESULTS

Of a total of 167 ureteral units undergoing surgery, persistent reflux immediately after surgery was observed in 17 cases (10% of the sample). Only 3 cases had other urological malformations. In the SVCU carried out after 3 months, reflux was found in 38% of the sample (64 cases). When comparing the results, intraoperative SVCU demonstrated a specificity of 92.6%, and a sensitivity of 15.6%.

CONCLUSIONS

Given the low sensitivity (15.6%) of intraoperative SVCU to detect cases of persistent reflux in the mid-term, and considering the risks associated with radiation in the pediatric population - which is extremely sensitive to it -, intraoperative SVCU should be ruled out as a useful indicator of endoscopic treatment success.

Endoscopic management of recurrent tracheoesophageal fistula with trichloroacetic acid in pediatric patients

INTRODUCTION

Surgical repair of recurrent tracheoesophageal fistula has a high risk of complications. Therefore, various endoscopic techniques have been used to avoid complications.

OBJECTIVE

To understand the usefulness of trichloroacetic acid endoscopic application for the treatment of recurrent tracheoesophageal fistula.

MATERIALS AND METHODS

An observational, descriptive, retrospective, case-series-based study was carried out in a tertiary pediatric hospital. Records of patients with recurrent tracheoesophageal fistula from 2015 to 2021 were reviewed. All patients within this period underwent brushing and trichloroacetic acid application.

RESULTS

Mean time of recurrent tracheoesophageal fistula occurrence was 4.8 months (range: 1-19.2). Two patients had a small fistula (less than 4 mm), three patients had a medium fistula (4 mm), and two patients had a large fistula (more than 4 mm). Mean sessions for fistula closure were 2.2 (range: 1-4). Mean time between procedures was 22 days (range: 14-30). Mean follow-up since fistula closure confirmation was 33 months (range: 9-72), during which no recurrences were noted.

CONCLUSION

Endoscopic management of recurrent transesophageal fistula with trichloroacetic acid is a safe and effective procedure. Brushing and trichloroacetic acid combined improve success rates. Fistulas over 4 mm in diameter require more procedures. However, a larger patient cohort and a longer follow-up period are needed to confirm this.

Management of Staple Line Leaks after Laparoscopic Sleeve Gastrectomy

Background and Objectives:

Laparoscopic sleeve gastrectomy has become one of the most popular bariatric surgeries in the United States with a low rate of morbidity and effective weight loss. However, staple line leak remains a feared complication requiring a lengthy and difficult treatment course until resolution. This study outlines the various treatment methods used within a high-volume bariatric practice for successful leak resolution without necessitating a conversion procedure.

Methods:

A retrospective review was conducted on all patients with staple line leak after laparoscopic sleeve gastrectomy in a three-surgeon bariatric practice from January 1, 2010 to December 31, 2019.

Results:

A total of 10 staple line leaks were identified with a leak rate of 0.9%. Patients presented on average 29.3 days postoperatively and were all diagnosed on computed tomography. Three patients were initially managed operatively with washout and drainage procedure. Six patients were managed endoscopically initially with either stent or over-the-scope clip placement. Most patients required multiple interventions with an average of 2.4 interventions per patient. Average time to leak resolution was 48.2 days (15–95 days).

Conclusion:

Management of staple line leaks after laparoscopic sleeve gastrectomy requires a multimodal approach usually requiring multiple interventions before leak resolution. We demonstrate effective utilization of varying interventions that lead to effective leak resolution and avoid conversion operations.

Prognostic factors of trochanteric bursitis in surgical-staged patients: a prospective study

BACKGROUND

Trochanteric bursitis or greater trochanteric pain syndrome is a common disorder and frequent cause of lateral hip pain. It can lead to severe functional impairment with increase morbidity and poor quality of life.The purpose of the current study was to identify and evaluate relationship between health-related factors, as prognostic indicators, and clinical outcomes.

METHODS

A single-centre, prospective study was conducted and 60 patients (62 hips) were included with a minimum 12 months of follow-up. Clinical outcomes were evaluated using Hip Outcome Scale, Single Assessment Numeric Evaluation and Visual Analogue Scale. Radiological assessments and health-related factors were documented in an attempt to understand their validity as predictors of clinical outcomes. Complications and recurrence rates were also analyzed.

RESULTS

Univariate model revealed that an increased BMI (p = 0.001; OR = 1.05; 95% CI, 1.02-1.07); number of previous corticosteroid infiltrations (p = 0.001; OR = 1.28, 95% CI, 1.11-1.48); longer time from symptom onset to surgery (p = 0.001; OR = 1.19; 95% CI, 1.12-1.28); smoker status (p = 0.001; OR 11.2; 95% CI, 3.30-44.2); and the presence of prior lumbosacral fusion (LSF) (p = 0.001; OR 13.8; 95% CI, 2.96-101); were prognostic factors predisposing for poor clinical outcomes.Among prognostic health-related factors were medical comorbidities such as emotional distress (p < 0.001; OR 26.1; 95% CI, 5.71-192); fibromyalgia (p = 0.026; OR 3.56; 95% CI, 1.16-11.7); and hyporthyroidism (p = 0.005, OR = 6.55, 95% CI, 1.73-28.7).

CONCLUSIONS

Better overall physical function was predicted by lower number of corticosteroid infiltrations, shorter time span from symptom onset to surgery, non-smoker status and the absence of prior lumbosacral fusion. Obesity, smoking, the presence of emotional distress, fibromyalgia and hypothyroidism seem to increase the risk of poor clinical outcomes. A proper selection and/or correction of modifiable prognostic factors could reduce the incidence of endoscopic treatment failure and, as a consequence, improve patient outcomes and quality of life. However, future efforts should focus on experimental and randomised studies to fully determine these associations.

Esophagogastric junctional neuroendocrine tumor with adenocarcinoma: A case report

BACKGROUND

At present, cases of esophageal neuroendocrine tumors combined with cardia adenocarcinoma are extremely rare worldwide, and there are no clinical reports. Herein, we describe such a case for clinical reference.

CASE SUMMARY

The presence of cardia cancer and esophageal neuroendocrine tumors in a single patient has not yet been reported. The patient in this case underwent prompt endoscopic treatment and additional surgical resection. Pathology revealed the following: The distance between the cardia cancer and the esophageal neuroendocrine tumors was small, approximately 3 mm. Vascular invasion was observed. The esophageal neuroendocrine tumor was determined to be grade G3. According to the treatment guidelines, after the patient received an explanation of their condition, additional surgical procedures were provided in a timely manner. Early detection and early treatment can successfully prolong survival and improve the quality of life of patients.

CONCLUSION

Early detection and early treatment can successfully prolong survival and improve the quality of life of such patients.

Reconstructing the puzzle of the role of therapeutic endoscopy in the management of post-bariatric surgery complications

We have recently read with interest the mini-review article "Therapeutic endoscopy for the treatment of post-bariatric surgery complications". The abovementioned article is a brief overview of the different endoscopic modalities employed in the management of bariatric surgery complications and represents an important decision support tool for clinicians to improve their current practice. Although we appreciate the endeavor of Larsen and Kozarek, based on our in-depth analysis, we came across several minor issues in this article; thus, we present our comments in this letter. In case the authors contemplate these comments in their relevant research, we believe that their contribution would be considerable for future studies.

Comparable long-term survival of patients with colorectal or gastric gastrointestinal stromal tumors treated with endoscopic vs. surgical resection

BACKGROUND AND AIMS

With the development of endoscopic technology, endoscopic treatment has been widely used in Gastrointestinal stromal tumors (GISTs). However, population-based studies comparing the long-term results of patients who received endoscopic treatment vs. Surgery are lacking. We used the Surveillance, Epidemiology, and End Results (SEER) database to analyze the long-term survival of colorectal or gastric GISTs who underwent primary tumor resection (endoscopic therapy or surgery) in the USA.

METHODS

Patients with colorectal or gastric GISTs were selected from the SEER database between 2010 and 2015. Kaplan-Meier analyses and log-rank tests were used to evaluate the difference in the long-term survival between the endoscopic therapy group and the surgery group. We examined the association between different treatments and survival after using the multivariate cox proportional hazards model to adjust the relevant covariates. Besides, we used Propensity score matching (PSM) to overcome the different distributions of covariates between the two groups and then further compare the survival difference.

RESULTS

In total, 2355 patients were enrolled in our study, of which 1999 (84.9%) received surgical treatment and 356 (15.1%) received endoscopic treatment. There was no significant difference in overall survival (OS) between the two groups before PSM. The median OS (73.5 months vs. 72.2 months) and 5-year OS rate (85.7% vs. 81.5%) of endoscopic therapy were similar to surgical patients (P = 0.34). The median Cancer-specific survival (CSS) and 5-year CSS rate in the endoscopic treatment group were higher than the surgical group before PSM, with 81.3 months, 97.1% versus 78.8 months, 92.7% (P = 0.011). After adjusting for other clinical factors and PSM, the long-term OS and CSS did not significantly differ between those treated surgically and treated endoscopically.

CONCLUSION

Based on the American population, we preliminarily found that the long-term OS and CSS did not differ between patients undergoing endoscopic therapy and surgery.

Risk factors for metastasis and survival of patients with T1 gastric neuroendocrine carcinoma treated with endoscopic therapy versus surgical resection

Background

Gastrectomy with lymphadenectomy is recommended for early gastric Neuroendocrine carcinoma (G-NEC). We attempted to determine the prevalence and risk factors of metastasis of T1 G-NEC and compare the long-term survival of patients after receiving endoscopic therapy (ET) and radical surgery.

Methods

In this study, 205 patients in total with T1 G-NEC were collected from the Surveillance Epidemiology and End Result database. Independent predictors of metastasis were identified by Logistic regression analysis, followed by the calculation of both cancer-specific survival (CSS) and overall survival (OS).

Results

Twenty-five patients (12.2%) were burdened with metastasis at initial diagnosis, with a prevalence of 5.2% (3/58) in mucosa lesions and 16.2% (16/99) in submucosa lesions (P = 0.045). No metastasis was detected in lesions with mucosa involvement and tumors ≦ 20 mm (0%, 0/49). The most significant risk factor for metastasis was tumors > 20 mm [odds ratio (OR) 18.64; 95% confidence interval (CI) 4.01–86.68; P < 0.001]. For patients with T1N0M0 G-NEC who received ET or surgery, the 10-year OS was similar between the mucosa extension and submucosa extension groups, which was 91.56% in ET group vs 87.50% in surgery group (P = 0.62) and 57.33% vs 77.83% (P = 0.11), respectively. In addition, the 10-year CSS was also similar between the mucosa extension and submucosa extension groups with 97.30% in ET vs 100% in surgery (P = 0.51) and 97.62% vs 86.49% (P = 0.65).

Conclusions

In G-NEC, tumors > 20 mm were considered as the most significant risk factor for metastasis. ET seemed adequate for the lesions with mucosa involvement and size ≦ 2 cm.

Endoscopic Management of Luminal Strictures: Beyond Dilation

Luminal strictures can occur as part of many different gastrointestinal (GI) disorders anywhere along the GI tract and affect all age groups. The end goal of managing any stricture is to re-establish an adequate and durable luminal patency that is sufficient to resolve the presenting clinical symptoms. Treatment options can be generally categorized into medical, endoscopic, and surgical. However, within each of these categories, multiple different options are available. Therefore, choosing the best treatment modality is often challenging and depends on multiple factors including the type, location, and complexity of the stricture, as well as the preference of the treating physician. In this article, we will review the most current literature regarding foregut strictures, particularly esophageal and gastric, beyond dilation.

[Efficacy Evaluation of Three Endoscopic Therapies of Isolated Gastric Varices with Modified Tissue Adhesive]

Objective

To evaluate the efficacy of three endoscopic therapies of isolated gastric varices (IGV) with modified tissue adhesive.

Methods

A retrospective analysis was conducted with the clinical data of 73 IGV patients who were treated between January 2008 and December 2019 at Beijing Ditan Hospital. Patient clinical data on age, sex, etiology, biochemistry findings, Child-Pugh classification, the type of spontaneous shunt, preoperative bleeding history, and the presence or absence of liver cancer were collected. The three therapies evaluated were endoscopic intravenous injection of tissue glue combined with lauromacrogol, endoscopic clip-assisted intravenous injection of tissue glue combined with lauromacrogol, and endoscopic clip and LOOP-assisted intravenous injection of tissue glue combined with lauromacrogol. Their respective clinical treatment outcomes, including ectopic embolism rate, survival rate, rebleeding rate, amount of lauromacrogol and tissue glue used, the number of endoscopic clips used, and the number of times of the procedure the patient underwent, were evaluated.

Results

In the patient baseline data, Child-Pugh grade, preoperative thrombus formation, and the presence or absence of liver cancer, showed significant difference between the three therapies ( P<0.05). There was no significant difference in the rates of ectopic embolism among the three methods ( P>0.05), but no ectopic embolism occurred after endoscopic clip-assisted intravenous injection of tissue glue combined with lauromacrogol, or after endoscopic clip and LOOP-assisted intravenous injection of tissue glue combined with lauromacrogol. There was no significant difference in the survival rate, the rebleeding rate, amount of lauromacrogol and tissue glue used for the three therapies, but there was significant difference in the number of endoscopic clips used and the number of times the procedure was conducted within one year ( P<0.05).

Conclusion

The two endoscopic therapies of intravenous injection of modified tissue glue, one assisted by clip and the other assisted by clip and LOOP, can help reduce the number of procedures IGV patients undergo within one year.

Safety and efficacy of common endoscopic treatments in patients with decompensated liver cirrhosis

INTRODUCTION

The safety and efficacy have always been a concern, when patients with decompensated liver cirrhosis (DLC) receive endoscopic treatments.

METHODS

To evaluate the safety and efficacy of common endoscopic treatments including endoscopic resection (ER) and endoscopic retrograde cholangiopancreatography (ERCP) applying to patients with DLC, we performed a retrospective study finally including 81 patients receiving ER (43 endoscopic mucosal resection (EMR) and 38 endoscopic submucosal dissection (ESD)) and 131 patients treated by ERCP.

RESULTS

There were no significant differences in the rate of degeneration and invariability of Child-Pugh (CP) class and the overall rate of adverse events between two groups (93.8%/8.6% ER vs. 96.2%/15.3% ERCP). Both the degeneration rate of CP class (35.4%) and the rate of adverse events (27.1%) in subgroup CP class C of ERCP group were significantly higher (P=0). The rate of poor outcomes was higher in ERCP group (12.2%) than that in ER group (2.5%) (P=0.02). And subgroup CP class C of ERCP group had a higher poor outcome rate (27.1%) (P=0).

CONCLUSION

ER and ERCP could remove focal lesions or relieve symptoms induced by targeted diseases without significant changes of CP class. Significant benefits and risks coexisted in CP class C patients with DLC when receiving ERCP.

Endoscopic treatment of ureterocele in children: Results of a single referral tertiary center over a 10 year-period

INTRODUCTION

The management of UCs remain controversial, especially for UCs with duplex collecting systems that still represent a great challenge in paediatric urology. Several approaches have been used and a shared management is not yet validated.

STUDY AIM

Aim of our study is to evaluate the results of the endoscopic treatment of UC comparing ortothopic single-system UC and ectopic duplex-system UC over a 10-year period in a single referral tertiary center. Success was defined as resolution of dilation, lack of urinary infections and preservation of renal function.

STUDY DESIGN

We retrospectively reviewed medical records of children with a diagnosis of UC who underwent endoscopic puncture at our division from January 2009 to January 2019. Patients were divided in two groups: Group A composed of patients with ectopic UC associated with renal duplex system and Group B with orthotopic UC in single collecting system.

RESULTS

We identified 48 paediatric patients treated with transurethral primary endoscopic incision. Groups result homogeneous for clinical and pathological characteristics. The only statistical significative difference between the two samples was the age at diagnosis (p value with Yates correction = 0.01).

DISCUSSION

We considered as a therapeutic success infections control and the elimination of obstruction with preservation of global kidney function. Based on that, our success rate after single (77%) or double (92%) endoscopic treatment is higher than data reported in literature. Differently from previous studies, vescico-ureteral reflux without UTIs was not considered as a failure of the procedure. The present study has some limitations: it is a retrospective and monocentric serie and it lacked a longer follow-up; on the other hand, it has been conducted on a quite large sample size and it is one of the few studies that compares the endoscopic treatment between orthotopic and ectopic UC.

CONCLUSION

Our data report primary endoscopic puncture of ureterocele as a simple, effective, and safe procedure also in long-term follow up. This technique avoids the need for additional surgery in the majority of the patients, also in the case of an ectopic UC associated to a duplex system.

The usefulness of combining the pocket-creation method with a traction device using a scissor-type knife for colorectal endoscopic submucosal dissection

INTRODUCTION

Technical issues and long procedure time still remain a concern in colorectal endoscopic submucosal dissection (ESD). We examined the usefulness of combining the pocket-creation method (PCM) with a traction device (S-O clip; SO) using a scissor-type knife (Clutch Cutter 3.5 mm; CC) for decreasing ESD procedure time.

METHODS

We retrospectively analyzed 95 ESD cases of PCM + SO + CC managed from August 2017 to April 2020 and 103 cases of PCM + CC treated from July 2016 to July 2017. We compared these two groups through propensity score matching. The main outcome was the analysis of the ESD procedure times under various conditions in each group.

RESULTS

After matching, 52 cases in the PCM + SO + CC and PCM + CC groups were analyzed. The PCM + SO + CC group showed a significantly shorter ESD procedure time than the PCM + CC group (57.8 ± 31.4 vs. 81.7 ± 33.5 min, p < 0.01). Additionally, the ESD procedure time was significantly shorter in the PCM + SO + CC group than in the PCM + CC group: tumor size (tumor size < 40 mm: 45.6 ± 15.8 vs. 72.7 ± 22.9 min, p < 0.01; tumor size ≥ 40 mm: 83.1 ± 40.1 vs. 111.8 ± 45.3 min, p = 0.04), tumor location (right side: 64.7 ± 33.3 vs. 81.0 ± 29.7 min, p = 0.03; left side: 50.5 ± 28.0 vs. 82.3 ± 36.9 min, p < 0.01), tumor morphology (polypoid: 39.2 ± 18.6 vs. 74.7 ± 28.6 min, p < 0.01; nonpolypoid: 62.3 ± 32.3 vs. 84.5 ± 35.2 min, p < 0.01), endoscopist (expert: 67.3 ± 41.2 vs. 91.9 ± 40.2 min, p = 0.02; nonexpert: 50.4 ± 18.3 vs. 73.6 ± 24.9 min, p < 0.01), and fibrosis (severe fibrosis: 82.0 ± 20.5 vs. 99.8 ± 40.4 min, p = 0.169; non-severe fibrosis: 52.1 ± 23.8 vs. 75.6 ± 29.0 min, p < 0.01).

CONCLUSIONS

The combination of the PCM and SO using CC achieved a reduction in the colorectal ESD procedure time.

Endoscopic treatment of paediatric subglottic stenosis and cyst (with video)

OBJECTIVE

The aim of this article is to describe step by step the endoscopic treatment of acquired subglottic stenosis (SGS) in an infant and to show the endoscopic results one month after surgery.

STUDY DESIGN

Case presentation with instructional video.

SETTING

University Hospital of Verona, Italy.

METHODS

We present the case of a 6-month-old ex-26-week preterm female infant who required prolonged intubation in the neonatal period. She referred to our hospital for persistent inspiratory and expiratory stridor, and laboured breathing. The endoscopic dynamic examination of upper airway revealed the presence of type 3 laryngomalacia and subglottic stenosis grade III according to Myers-Cotton classification. An endoscopic balloon laryngoplasty was planned. Two laryngeal dilatations were performed. The endoscopic exploration after the first dilatation showed the presence of a subglottic cyst on the anterior surface of the subglottis. The treatment of subglottic cyst consisted of marsupialization of the cyst with cold microinstruments, and subsequent suction of its content.

RESULTS

An endoscopic check-up was carried out one month after surgery. The examination of the upper airway under spontaneous respiration didn't show significant subglottic stenosis. A very small subglottic cyst under the anterior commissure was observed. However, no more balloon dilatations or marsupialization of the cyst were performed in order to avoid the formation of synechiae.

CONCLUSION

Treatment of SGS must be planned according to the extent of the stenosis and the history of the patient. Endoscopic procedures, such as balloon dilatation and cyst marsupialization, are best chosen for patients with isolated SGS without prior treatment failure.

Endoscopic treatment of spondylodiscitis: systematic review

BACKGROUND

Spondylodiscitis is a severe condition where standalone antibiotic therapy resolves most cases. In refractory infections, open surgery may aid with infection debulking. However, significant morbidity can occur. Nowadays, endoscopic approaches are emerging as an alternative. However, until now, only small-scale studies exist. Being so, we carried the first systematic review on spondylodiscitis endoscopic debridement indications, technique details, and outcomes.

METHODS

Search for all English written original studies approaching the spondylodiscitis endoscopic treatment was performed using PubMed and EBSCO host. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a pre-specified protocol was registered at PROSPERO (CRD42020183657).

RESULTS

Fourteen studies involving 342 participants were included for analysis. Data overall quality was fair. Indications for the endoscopic approach were poorly defined. The most consensual indication was refractory infection to conservative treatment. Spinal instability or neurological deficits were common exclusion criteria. All authors described similar techniques, and despite the frequent severe co-morbidities, procedure morbidity was low. Re-interventions were common. Microorganism identification varied from 54.2 to 90.4%. Treatment failure among studies ranged from 0 to 33%. Pain, functional status, and neurological deficits had satisfactory improvement after procedures.

CONCLUSIONS

The endoscopic debridement of spondylodiscitis seems to be an effective and safe approach for refractory spondylodiscitis. A novel approach with initial endoscopic infection debulking and antibiotic therapy could improve the success of spondylodiscitis treatment.
