Inflammatory endobronchial polyps (IEPs) are rare, benign bronchial tumors posing diagnostic and therapeutic challenges owing to limited data. A 55-year-old man, receiving treatment for allergic bronchopulmonary aspergillosis, presented with a one-week history of fever and purulent sputum. Diagnosed with pneumonia, he received antimicrobial treatment. However, because of persistent symptoms, an endobronchial tumor was suspected on computed tomography. IEP was confirmed through flexible bronchoscopy with forceps biopsy, and polyp removal improved symptoms, lung function, and imaging.

UNASSIGNED: Flexible bronchoscopy is a less invasive procedure for extracting foreign bodies from the airways. However, studies on the extraction of headscarf pins are still very limited to determine the efficacy and safety of headscarf pin extraction using flexible bronchoscopy with biopsy forceps.
UNASSIGNED: This retrospective study was conducted at Persahabatan Hospital, Jakarta, Indonesia, on patients who had been treated in this hospital for headscarf pin extraction between January 2013 and February 2023. Fibreoptic bronchoscopy was performed under general anaesthesia. The pin was removed using Radial Jaw 4 mm single-use pulmonary biopsy forceps. The impacted sharp tip of the pin was freed first, and the proximal part of the pin body was gripped using biopsy forceps. Once a firm hold of the sharp end or the proximal part of the pin was secured, the bronchoscope and forceps were both slowly withdrawn under direct vision.
UNASSIGNED: Thirty-two cases with headscarf pin aspiration were managed by fibreoptic bronchoscopy. A total of 12 patients (37.5%) came without any respiratory complaints; however, an equal number complained of cough and 6 cases (18.7%) of haemoptysis. All the cases in which the pins were visible in the airway were found with the round head down and the sharp tip oriented superiorly in the airway and impacted in the mucosa. Fibreoptic bronchoscopy extraction succeeded in 31 cases (96.8%). Only one case was converted to surgery. There were no major complications.
UNASSIGNED: Fibreoptic bronchoscopy with biopsy forceps under general anaesthesia is safe and effective for the removal of headscarf pin aspiration.

UNASSIGNED: Afferent loop obstruction (ALO) can occur as a complication of gastrectomy with Billroth II or Roux-en-Y reconstruction. Conventionally, emergent surgery was performed for most cases, while endoscopic procedures for elective cases have been reported more recently. We report a unique case of ALO caused by a phytobezoar that was successfully treated by endoscopic procedures.
METHODS: A 76-year-old female patient presented with epigastric pain for several hours after dinner. The patient had a history of distal gastrectomy with Roux-Y reconstruction for gastric cancer at age 62. Computed tomography (CT) demonstrated evident dilation of the duodenum and common bile duct, and detected a bezoar at the jejunojujunal anastomosis site, indicating that the ALO was induced by the bezoar. Upper endoscopy visualized undigested food formation stuck at the anastomosis site, and it was successfully dislodged by endoscopic fragmentation using biopsy forceps. After the procedure, the abdominal symptoms subsided, and the patient was discharged on the fourth day.
UNASSIGNED: Bezoar-induced ALO is rare. In this case, CT helped diagnose the ALO induced by the bezoar. In recent times, there has been a rise in endoscopic interventions for ALO, and there are some reports of bezoar-induced small bowel obstruction being treated endoscopically. Therefore, a subsequent endoscopic examination was performed, confirming the presence of a phytobezoar and leading to a less invasive endoscopic fragmentation treatment in this case.
CONCLUSIONS: This is a unique case report of phytobezoar-induced ALO treated by endoscopic fragmentation of undigested food, providing a beneficial treatment option.

Cold snare polypectomy (CSP) is the preferred resection technique for small (6-9 mm) polyps due to lower rate of incomplete resection compared to cold forceps polypectomy (CFP) and improved safety profile over hot snare polypectomy (HSP).
To describe resection techniques for small (6-9 mm) polyps and determine factors associated with sub-optimal technique.
This was retrospective cohort study of colonoscopies performed by gastroenterological and surgical endoscopists from 2012 to 2019 where at least one 6-9 mm polyp was removed. Patient, provider, and procedure characteristics were collected. Univariate and multivariate regression analyses were performed to determine factors associated with sub-optimal technique.
In total, 773 colonoscopies where 1,360 6-9 mm polyps removed by 21 endoscopists were included. CSP was used for 1,122 (82.5%), CFP for 61 (4.5%), and HSP for 177 (13.0%). Surgeon specialty was associated with CFP use (aOR 7.81; 95% CI 3.02-20.16). Polyp location in left colon (aOR 1.65; 95% CI 1.17-2.33) and pedunculated morphology (aOR 12.76; 95% CI 7.24-22.50) were associated with HSP. There was a significant increase in overall CSP use from 30.4% in 2012 to 96.8% in 2019.
82.5% of all 6-9 mm polyps removed from 2012 to 2019 were removed using a cold snare with significant increase in CSP from 2012 to 2019. Differences in how optimal technique was adopted over time based on specialty highlight the need for standardized practice guidelines and quality monitoring.

Chronic gastroenteropathies, including gluten sensitivity and marmoset wasting syndrome, frequently occur in captive colonies of common marmosets (Callithrix jacchus). Early identification and diagnosis of affected animals are desirable. Endoscopic examination of the colon in marmosets is described, but the small intestine can harbor significant mucosal lesions not representing those in the colon. Evaluating the small intestine currently requires invasive surgical biopsies due to the small patient size, carrying a risk of severe complications.
Endoscopic intubation and multisite biopsy of the duodenum/proximal jejunum are demonstrated in 10 marmosets under general anesthesia.
Esophagogastroduodenoscopy with colonoscopy efficiently aid in examining the gastrointestinal tract and obtaining an antemortem histologic diagnosis in marmosets with chronic gastrointestinal signs.
This minimally invasive technique is feasible in marmosets. Future investigations into the pathogenesis of chronic gastroenteropathies will benefit from these data, leading to improved animal welfare and better individual and colony health management.

UNASSIGNED: Severe tilt with embedded hooks is a common obstacle to successful inferior vena cava (IVC) filter retrieval.
UNASSIGNED: Disposal biopsy forceps were used to remodel the filter hook in the center position to release the embedded hook from the caval wall.
UNASSIGNED: The biopsy forceps-assisted loop snare technique was successfully used to retrieve filters with hooks embedded in the IVC wall.
UNASSIGNED: The biopsy forceps-assisted loop snare technique we present here offers a new solution for the complex retrieval of IVC filters. This technique may prove useful in cases where standard techniques at filter retrieval fail.

A 76-year-old female who had a history of endovascular treatment (EVT) for her left superficial femoral artery with endovascular stent grafts [VIABAHN (W. L. Gore & Associates, Inc., DE, USA)] suddenly experienced intermittent claudication of her left leg. Angiography revealed total occlusion of previous stent grafts, and a thrombus aspiration catheter was used after crossing the guidewire. Since retrograde angiography using a thrombus aspiration catheter revealed a large residual thrombus at the distal edge of the previous stent even after several thrombus aspirations, biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)] were successfully used to remove that thrombus. After balloon inflation under distal protection, angiography revealed a large residual thrombus at her left common femoral artery with a flow limiting of her deep femoral artery. Again, biopsy forceps were successfully used to remove that thrombus. In this case series, we reported a total of 11 cases which underwent EVT using biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)]. Of the 11 cases, eight underwent EVT using biopsy forceps for thrombus removal, two underwent calcification removal in severely calcified lesions, and one underwent removal of a detached guidewire. There were no major adverse limb events (MALEs) except for one patient who underwent major amputation after EVT. One MALE occurred independently of biopsy forceps use because biopsy forceps were used only to remove the detached wire. Biopsy forceps for intestinal endoscopes were clinically useful and safe for EVT.

BACKGROUND: The present study aimed to compare the clinical results and pathological diagnostic quality of percutaneous transhepatic cholangiobiopsy for biliary obstruction using biopsy forceps (BFs) of varying diameter.
METHODS: A total of 57 patients with obstructive jaundice who underwent percutaneous transhepatic cholangiobiopsy and drainage with 1 of 2 BFs diameters (6.0-mm BFs, n=30; 4.5-mm BFs, n=27) between February 2018 and May 2019 were retrospectively assessed. BFs were compared in terms of their sample quality, diagnostic accuracy, sensitivity, specificity, number of passes, and complication rate.
RESULTS: All 57 patients underwent the procedure successfully and the technical success rate was 100%. The 6.0- and 4.5-mm BFs demonstrated a diagnostic accuracy of 80% (24/30) and 85% (23/27), respectively (P=0.733), and a sensitivity of 78% (22/28) and 86% (22/26), respectively (P=0.729). The specificity of both the 6.0- and 4.5-mm BFs was 100%. The complication rate was 10% (3/30) with the 6.0-mm BFs and 19% (5/27) with the 4.5-mm BFs (P=0.456). The mean number of biopsies was 2.9±0.6 with the 6.0-mm BFs compared with 3.6±1.0 with the 4.5-mm BFs (P<0.001). The 6.0-mm BFs provided a larger biopsy size and a less crushed specimen compared with the 4.5-mm BFs. The overall tissue scores were 5.2±0.8 with 6.0-mm BFs and 4.5±1.0 with 4.5-mm BFs (P=0.012).
CONCLUSIONS: There was no statistically significant difference in the clinical results between the 2 BFs in the context of percutaneous transhepatic cholangiobiopsy. Superior samples were obtained using the 6.0-mm BFs, with a fewer number of passes. The complication rate did not increase compared with the 4.5-mm BFs.

Although the importance of the retrieval of an optional inferior vena cava filter (o-IVCF) has gained attention because of the awareness of a high complication rate with long indwelling time, the o-IVCF retrieval rate remains low. The advanced retrieval technique of o-IVCF may increase the retrieval rate, which in turn diminishes future adverse events. Through two cases, we describe how to perform the novel approach \"bidirectional sling technique with biopsy forceps.\" This technique will improve the retrieval rate in patients following the failure by conventional retrieval technique.
