Endobronchial electrosurgery

Endobronchial electrosurgery (EBES) with the aid of a fiberoptic bronchoscope and a diathermic snare has been performed in 14 patients with tracheal and bronchial tumors (eight with benign, one with carcinoid, and five with malignant tumors). Total eradication has been achieved in the nine patients with benign and carcinoid tumors. In some patients, EBES was supplemented with surgical removal with the biopsy forceps or laser coagulation. Electroexcision of the endobronchial portion of the tumor helped to clear the respiratory airways in three of the five patients with malignant tumors. Emergent EBES was performed in two patients with acute respiratory failure and massive hemorrhage caused by adenocystic and thyroid cancer of the trachea.     

Resection of giant endobronchial hamartoma by electrocautery and cryotherapy via flexible bronchoscopy

Endobronchial hamartoma is a rare tumor which is 3-10% of all hamartomas. We presented a case of endobronchial hamartoma that was resected and ablated with electrocautery and cryotherapy by fiberoptic bronchoscopy. A 71-year-old male, presented with progressive dyspnea on exertion, chest pain and hemoptysis. Chest computed tomography (CT) scan of the patient revealed a mass lesion mostly obliterating tracheal lumen and left main bronchus. An initial bronchoscopy showed a large polypoid lesion within the left mainstem bronchus. Polypoid lesion protrudes to the right with respiration. Interventional bronchoscopy with snare probe of the electrocautery resected the polyp in 4 pieces followed by cryotherapy of the base. Pathology of the resected lesion diagnosed as bronchial hamartoma with fibrovascular component. Control bronchoscopy applied 10 days later revealed patency of all airways. The majority of hamartomas is parenchymal and is often located in the periphery of the lung, unlike our patient who had a more central lesion. Where a firm diagnosis is made preoperatively, surgical removal may not be necessary unless symptoms are present, or tumor expansion is noted. Our case demonstrates resection of an endobronchial hamartoma by snare probe of the electrocautery and with cryotherapy. Electrocautery and cryotherapy may present an alternative therapy for resection of selected benign endobronchial benign tumors.

Colon polyp retrieval after cold snaring

BACKGROUND: The removal of small colon polyps by cold snare transection without electrocautery effectively eliminates polyps, and anecdotal reports indicate a low risk of bleeding and perforation. Concerns about using cold snaring have centered on the risk of immediate bleeding and the difficulty in retrieving the polyp. The objective was to determine the retrieval rates of polyps after cold snaring after two different methods of resection and retrieval. METHODS: Consecutive polyps were identified by a single colonoscopist who chose the technique of polypectomy (hot snare, cold snare, or cold forceps). If cold snaring was chosen, an independent observer assigned the polyp to method A (cold resection of polyp without tenting and then suction of the transected polyp into a trap) or method B (ensnare the polyp, pull it into the colonoscope channel, and then transect it while suctioning). The size and the approximate location of all polyps were recorded and all collected specimens were sent separately for histologic examination. Results Of 519 consecutively encountered polyps, 400 were removed by cold snare: 197 were assigned to method A and 203 to method B. The mean size of polyps that were cold snared was 3.5 mm. The mean time to remove and to retrieve polyps with method A was 14.5 seconds (n = 58) and with method B was 18.1 seconds (n = 60) ( p = 0.03). There were no complications from cold snaring. The rate of successful retrieval with method A was 100% (197 of 197 polyps) and with method B was 98% (199 of 203 polyps) ( p = 0.04). CONCLUSIONS: Cold snare removal of colon polyps is associated with a high polyp retrieval rate. Each of two methods of polyp retrieval was effective. Snare transection without tenting of the polyp, followed by suctioning of the specimen off the polyp site, was more efficient, though the difference in efficiency was minimal. Difficulty or failure to retrieve polyps should not be a concern with regard to cold snare polypectomy.     

Endobronchial electrocautery

Endobronchial electrocautery was successfully used to treat three patients with major airway obstruction resulting from bronchogenic carcinoma and to establish a diagnosis in a fourth. Electrocautery was applied through fiberoptic bronchoscopes. In two cases, a wire snare was used to remove polypoid lesions and in two others, probes were used to ablate tumor tissue. As a result of high inspired oxygen concentration in one patient, a tracheal fire occurred without injury to the patient. Electrocautery is an available economical tool which has potential value in the diagnosis and therapy of endobronchial obstructing airway lesions.     

Endoscopic submucosal dissection of gastric neoplasms using a snare tip

Background: Endoscopic submucosal dissection (ESD) enables the complete removal of gastric lesions regardless of tumor size. ESD is typically performed using one of several available electrocautery knives and endoscopic mucosal resection (EMR) is performed using a diathermic snare. We aimed to investigate the clinical outcomes and complications in patients in whom a snare tip was used for ESD.

Materials and methods: We retrospectively evaluated the medical records of 30 patients who underwent removal of a gastric lesion using a snare tip by ESD or hybrid ESD (ESD with snaring). For hybrid ESD, snaring was performed after an adequate submucosal dissection. The clinical outcomes according to the endoscopic procedure performed were evaluated.

Results: ESD was performed in 12 patients and hybrid ESD was performed in 26 patients. Overall en-bloc and complete resection rates were both 97.4%. There was one case where piece-meal resection was performed in the hybrid ESD group. There were no procedure related complications such as perforation or bleeding. The mean specimen size was 2.8?±?0.6?cm in the ESD group and 2.3?±?0.5?cm in the hybrid ESD group (p?=?.031). The mean procedure time did not differ between the two methods (12.8?min in ESD and 9.7?min in hybrid ESD, p?=?.060).

Conclusions: The snare tip can be used as an electrocautery knife to incise the mucosa and dissect the submucosa during removal of a gastric lesion.     

Endoscopic argon plasma coagulation of Marlex mesh erosion after vertical-banded gastroplasty

BACKGROUND: Marlex mesh erosions may occur as late complications after vertical-banded gastroplasty. Experience with the endoscopic treatment is limited. OBJECTIVE: To describe the use of argon plasma coagulation in the endoscopic treatment of eroded Marlex mesh. DESIGN: Case report. SETTINGS: Endoscopy Unit, University of Iowa Hospitals and Clinics, Iowa City, Iowa, USA. PATIENTS: We describe the endoscopic treatment of eroded Marlex mesh in 2 patients who presented with symptoms of gastric-outlet obstruction. INTERVENTIONS: In both cases, argon plasma coagulation was used to break down the eroded Marlex mesh. Fragments were subsequently removed with forceps and electrocautery snares. We did not encounter any complications with this method. RESULTS: The endoscopic treatment resulted in lasting symptomatic improvement in both patients. LIMITATIONS: Our experience is limited to 2 cases. CONCLUSIONS: Argon plasma coagulation appears to be a promising option for the endoscopic treatment of eroded Marlex mesh. It allows the fragmentation of large mesh portions and enables subsequent removal with a snare and a forceps. This method can result in symptomatic improvement and may obviate the need for surgery. Further data are necessary to evaluate the safety and the efficacy of this approach.     

Endobronchial lipoma: review of 64 cases reported in Japan

BACKGROUND: Several recent studies discuss bronchoscopic techniques for treating endobronchial lipoma, an extremely rare benign tumor. OBJECTIVES: To describe the epidemiology of endobronchial lipoma and to propose appropriate therapeutic policies for treating this tumor. METHODS: We reviewed 64 cases of endobronchial lipoma: 33 cases previously reported in 30 different articles, and 31 case reports presented at thoracic meetings in Japan. RESULTS: Of the 64 patients included in this study (50 male and 14 female; mean age, 60 years), 40 patients had endobronchial lipoma in the right lung and 23 patients had it in the left lung. The overwhelming majority of the tumors (n = 61) were found in the first three subdivisions of the tracheobronchial tree. Forty-eight patients (75%) were symptomatic, and their symptoms included cough, sputum, hemoptysis, elevated temperature, and dyspnea. Additionally, abnormal radiographic findings were reported for 51 patients (80%): 18 patients had atelectasis, 14 patients had infiltration or consolidation, 6 patients showed volume loss of the lung, and mass shadow was identified in 9 patients, and another abnormality including pleural effusion was found in 4 patients. Forty patients underwent surgical resection: 4 pneumonectomies, 24 lobectomies, 8 bilobectomies, and 4 resections by bronchotomy. Bronchoscopic resection was carried out in 17 cases: 7 cases by Nd-YAG laser, 5 cases by electrosurgical snaring forceps, and another 5 cases with a combined therapy using both procedures. CONCLUSIONS: Bronchoscopic resection should be considered as the first choice of treatment for endobronchial lipoma; however, surgical therapy is indicated for patients who show the possibility of a complicated malignant tumor, who have destructive peripheral lung disease, who have extrabronchial growth, or who may have technical difficulties during the bronchoscopic procedure.     

Circumferential EMR and complete removal of Barrett's epithelium: a new approach to management of Barrett's esophagus containing high-grade intraepithelial neoplasia and intramucosal carcinoma

BACKGROUND: There is no study of circumferential EMR in patients with Barrett's esophagus containing early stage malignant lesions. This study investigated the effectiveness and safety of circumferential EMR by using a simple snare technique without cap. METHOD: Patients with Barrett's esophagus containing multifocal high-grade intraepithelial neoplasia or intramucosal cancer, and patients with endoscopically nonidentifiable early stage malignant mucosal changes incidentally detected in random biopsy specimens were included in the study. A 30 x 50-mm polypectomy snare made of monofilament 0.4-mm steel wire was used without any additional device or submucosal injection. RESULTS: Twelve patients (10 men, 2 women; median age 63.5 years, range 43-88 years) underwent circumferential EMR; 5 had multifocal lesions, and 7 had no visible lesions. Segments of Barrett's epithelium were circumferential (median length 5 cm) and completely removed. The median number of EMR sessions was 2.5. The median number of snare resections per EMR session was 5. The medial total area of mucosa in resected specimens per session was 3.8 cm(2). Two patients developed strictures that were successfully treated by bougienage. Minor bleeding occurred during 4 of 31 EMR sessions. During a median follow-up of 9 months, no recurrence of Barrett's esophagus or malignancy was observed. CONCLUSIONS: Circumferential EMR with a simple snare technique is feasible, safe, and effective for complete removal of Barrett's epithelium with early stage malignant changes.     

Endobronchial brachytherapy in the treatment of malignant lung tumours.

A prospective study was made to assess the short-term clinical and endoscopic response to high-dose-rate endobronchial brachytherapy (HDREB) in patients with malignant endobronchial tumours. From July 1995 to May 2000, 288 HDREB sessions were carried out on 81 patients. The mean patient age was 61.57 yrs (range 34-82); males were predominant (87.65%). Tumours were primary in 76 patients (93.82%) and metastatic in five patients (6.18%). The inclusion criteria were malignant endobronchial tumour and either palliative treatment for incurable disease or intent-to-cure treatment for residual malignancy on the bronchial resection surface after surgery or an inoperable tumour. The exclusion criteria were as follows: impediments to catheter placement, expected survival <2 months, Karnofsky index <60, or absence of informed consent. The clinical response of a symptom was categorised as complete (disappearance of the symptom), partial (less than complete) or absent. The endoscopic response was considered to be complete if lesions disappeared and biopsy findings remained negative 1 month after the last radiation session; partial if lesions improved to some extent, but the biopsy findings were positive; and absent if there was no change in relation to baseline. The technique consisted of delivering high-dose irradiation from an Ir192 source to a target volume using one or two endobronchial catheters inserted under optical or video bronchoscopic guidance. Four sessions were scheduled at weekly intervals and 500 cGy was applied per session over a length of 1-9 cm, measured 0.5-1 cm from the centre of the source. In total, 85% of the symptoms analysed (haemoptysis, cough, dyspnoea, expectoration, and stridor) disappeared with HDREB, which was categorised as a complete response. The endoscopic response was complete in 56.79% of patients, partial or less than complete in 40.74% and absent in 2.46%. One major complication occurred (bronchial fistula 1.2%), but no lethal haemoptysis. Minor complications (pneumonitis, bronchospasm and bronchial stenosis) each occurred in one patient (1.2%). High-dose-rate endobronchial brachytherapy is a good palliative treatment for endoluminal lung neoplasms, effectively alleviating symptoms and endoscopic evidence in many cases with an acceptable rate of complications. High-dose-rate endobronchial brachytherapy can be carried out as an intent-to-cure procedure in highly selected cases.     

Grasping forceps assisted endoscopic resection of large pedunculated GI polypoid lesions.

BACKGROUND: Endoscopic resection of pedunculated polyps with heads 1 cm or greater in diameter is technically complex. To facilitate removal of such polyps, we developed grasping forceps assisted endoscopic resection in which we use a detachable snare to prevent polypectomy-related bleeding and evaluated the usefulness and safety of the procedure. METHODS: Ten patients with pedunculated polyps with heads 1 cm or greater in diameter were treated with this technique. A two-channel endoscope, grasping forceps, electrosurgical snare, and detachable snare are needed for the procedure. RESULTS: All lesions were easily and safely resected. During this procedure, a two-channel endoscope with grasping forceps proved to be satisfactory for handling the detachable snare and the electrosurgical snare and for accurate recognition of the stalk under good visual control. No hemorrhage, perforation, or other complication occurred as a result of use of this new technique. CONCLUSIONS: Grasping forceps assisted endoscopic resection of polyps with a detachable snare is an effective method for the prevention of polypectomy-associated bleeding. This technique makes it technically easier to resect large pedunculated polypoid lesions of the GI tract.     

Combining bronchoscopy and positron emission tomography for the diagnosis of the small pulmonary nodule < or = 3 cm

AIM: To assess the role of bronchoscopy and positron emission tomography (PET) scanning in an integrated approach for the diagnosis of noncalcified, small, chest radiologic lesions (< or = 3 cm). METHODS: Seventy-four consecutive patients (29 men; mean age, 64 years) with a pulmonary nodule < or = 3 cm undergoing both combined PET and bronchoscopy were included. When bronchoscopy and PET findings were negative, a multidisciplinary decision was taken to perform further invasive diagnostics or follow-up. RESULTS: Malignancy was diagnosed in 51 patients (69%), and a positive benign diagnosis was made in 9 patients (12%). Six patients (8%) had endobronchial lesions. Bronchoscopy was diagnostic in 53% patients (cancer, n = 35; benign, n = 4). PET findings were positive in 19 of 35 patients with a nondiagnostic bronchoscopy. In these 19 patients, malignant diagnosis was made in 14 patients (CT-fine needle aspiration [FNA], n = 3; thoracoscopic biopsy, n = 3; resection, n = 7; FNA of PET-positive supraclaviclar lymph node, n = 1), and a benign diagnosis was made in 5 patients (CT-FNA, n = 1; thoracoscopic biopsy, n = 1; resection, n = 1; follow-up, n = 2). In 16 patients with nondiagnostic bronchoscopy and negative PET findings, 5 patients had a tissue diagnosis (cancer, n = 2 [< 1 cm]; benign, n = 3) and 11 patients were followed up. Sixty-seven patients had a lesion 11 mm to 3 cm; among these, all 12 patients who were bronchoscopy negative and PET negative had benign lesions. In 24 patients without mediastinal adenopathy (solitary pulmonary nodule), bronchoscopy was diagnostic in 12 patients (cancer, n = 11; bronchiolitis obliterans organizing pneumonia, n = 1). In the remaining 12 patients, PET findings were positive in 6 patients (cancer, n = 3; resection, n = 2; CT-FNA, n = 1) and negative in 6 patients (benign, n = 2, both on resection; follow-up, n = 4). CONCLUSION: Combining bronchoscopy and PET scanning has an useful role in the diagnosis of noncalcified chest radiologic lesions < or = 3 cm in size. Bronchoscopy has a diagnostic yield of > 50% and also allows the diagnosis of endobronchial lesions. If bronchoscopy is nondiagnostic, a PET scan should be performed.     

Management of type-I gastric neuroendocrine neoplasms: A 10-years prospective single centre study

BackgroundThis study aimed to evaluate the outcome of patients with type 1 gastric neuroendocrine neoplasia (T1gNENs) treated with different endoscopic approaches.MethodsPatients were managed with endoscopic surveillance at regular intervals. Resection was performed by forceps or cold snare in tumours < 10 mm, otherwise mucosal resection (EMR) or submucosal dissection (ESD) were done.Results127 T1gNENs, detected in 80 patients, were included. 87.4% of them were <5 mm, whereas 8.7% were 6–10 mm, 3.1% were 11–20 mm, and 0.8% was >20 mm. Ki67 <3%% was found in 85.8% tumours, whereas it was 3%-20% in the remaining 14.2% lesions. Noninterventional management (surveillance without radical resection) was performed in 15 patients (18.7%) with T1gNENs <5 mm. None of them underwent disease progression during follow-up. among the 65 patients treated by radical endoscopic resection, 37 patients (56.9%) had disease recurrence. 48.5% T1gNENs were removed by forceps, 16.8% by cold snare, 31.7% by EMR and 3% by ESD. The recurrence rate was similar among the different endoscopic techniques used.ConclusionsThe management of T1gNENs may be planned based on tumour size. T1gNENs < 5 mm for which the initial removal is not radical could be followed up by noninterventional endoscopic surveillance.     

High diagnostic yield from transbronchial biopsy of solitary pulmonary nodules using low‐dose CT‐guidance

Background and objective: The diagnostic yield from fluoroscopy‐guided bronchoscopic transbronchial biopsy of small solitary pulmonary nodules is low. The hypothesis tested in the present study was that the diagnostic yield can be significantly increased by combining flexible bronchoscopy with CT‐guidance using a dedicated low‐dose protocol. Methods: CT‐guided transbronchial biopsies were performed in 15 patients with a newly diagnosed solitary peripheral pulmonary nodule and negative conventional bronchoscopic biopsies under fluoroscopic guidance. For imaging, a multi‐detector helical CT unit, adjusted at 120 kV, 15 mAs/slice, 4 × 5 mm collimation, 10 mm reconstructed slice thickness and a maximal scan length of 150 mm, was used. After advancing the biopsy forceps towards the lesion, a CT scan was obtained. When the tip of the forceps reached or penetrated the lesion a biopsy was taken, otherwise the procedure was repeated with a maximum of eight attempts. The effective radiation dose was calculated. Results: The average diameter of the nodules was 23 ± 6 mm (mean ± SD) with a maximum distance to the parietal pleura of 18 mm (mean 6.5 mm). A mean of 4.1 (range 2–8) CT scans was performed to localize the lesion. In four patients, the forceps only reached the periphery of the nodule. In one patient, the nodule was missed in all attempts. Histology was malignant in eight patients and benign in four patients. In three patients, biopsy results were false negative (benign or non‐specific instead of malignant). The overall diagnostic yield was 73%. Complications consisted of two pneumothoraces, one of which necessitated a chest tube. Mean effective radiation dose was 0.55 mSv (range 0.3–1.0). Conclusions: CT‐guided transbronchial biopsy can be a valuable diagnostic tool in evaluating solitary pulmonary nodules. This applies for selected patients when other diagnostic methods are either unavailable or inappropriate. The diagnostic yield is high and, when a low‐dose protocol is used, radiation exposure can be kept at a minimum.     

冷圈套联合黏膜下注射对结直肠(微)小息肉的完整切除率的研究

目的肠镜下切除的结直肠息肉绝大多数为微小息肉(≤5 mm)或小息肉(6～10 mm),对于此类息肉的最佳切除方法目前缺乏统一指南。本研究旨在探究冷圈套息肉切除术联合黏膜下注射治疗结直肠息肉(直径≤10 mm)的可行性和有效性。 方法本研究前瞻性随机选取2018年1月至2018年12月经解放军联勤保障部队第九〇〇医院消化内科行结肠镜检查发现结直肠息肉(直径≤10 mm)的300例患者进行对照研究,按1∶1随机分配接受冷圈套息肉切除术联合黏膜下注射(CSPI)或冷圈套息肉切除术(CSP)治疗。其中CSPI组在切除息肉之前先进行黏膜下注射,再行息肉切除,而CSP组则套取息肉后直接切除,然后在内镜窄带成像技术(NBI)引导下对息肉切除部位底部及侧切缘活检2～3块,用于病理组织学评估切除完整率。术中记录息肉切除时间、息肉回收情况和并发症。 结果纳入研究的300例患者,CSPI组(n ＝150)和CSP组(n＝150)病灶平均大小分别为7.7 mm和6.7 mm。患者的性别、年龄等及息肉部位、大小、形态、分型在组间均衡。CSPI与CSP相比完全切除率为96.7% vs 76.6%,差异具有统计学意义(P<0.001)。所有息肉均回收,其中9例CSP患者出现术中出血,CSPI组无术中出血,差异具有统计学意义(P<0.05);所有患者均无迟发性出血、穿孔等并发症。 结论尽管CSPI较单纯采用冷圈套的治疗时间长,但却是一种安全、有效的息肉切除术,尤其对于6～10 mm息肉其全切除率高达98.9%,并且手术相关并发症发生率较低。     

Cold snare polypectomy: Indications,devices, techniques,outcomes and future

Colonoscopy has been shown to reduce the risk of colon cancer by enabling the removal of precancerous lesions. Although cold snare and hot snare polypectomy have similar retrieval rates and complete resection rates, rates of delayed bleeding tend to be lower with cold snare polypectomy than with hot snare polypectomy, especially for patients taking antithrombotic agents. However, among cold snares there may be differences in terms of the completeness of polyp excision, as complete removal appears more likely with thin‐wire dedicated cold snares compared to the traditional, thick‐wire cold snares. Cold snare polypectomy may be especially well suited for use in patients taking antithrombotic agents, due to its minimal risk of delayed bleeding. Histological analyses suggest that cold snare polypectomy causes less damage to blood vessels in the submucosal layers, which results in a reduced incidence of hemorrhage compared to hot snare polypectomy. However, cold snare removal of small polyps may result in fragmentation of small specimens during collection and concerns as to whether the resection is complete. An endoscopy biomarker of effective cold snare polypectomy technique is needed to ensure complete removal of non‐pedunculated colorectal polyps ≤10 mm. Future uses of cold snare polypectomy may include piecemeal removal of sessile serrated adenoma/polyp lesions >10 mm. Currently, cold snare polypectomy should be considered a primary method for colorectal polyps of less than 10 mm, especially those in the 4‐ to 10‐mm range.     

Colonoscopic Polypectomy Preferences of Asian Endoscopists: Results of a Survey-Based Study

Background/AimsThe clinical practice pattern of polypectomy is not well-investigated in Asian countries. We aimed to survey Asian endoscopists about their preferred polypectomy techniques for given conditions and images of polyps.MethodsA survey was performed using questionnaires composed of two parts a scenario-based questionnaire using scenarios of polyps, which were adopted from the European Society of Gastrointestinal Endoscopy guidelines, and an image-based questionnaire using provided endoscopic images of polyps.ResultsA total of 154 endoscopists participated in this survey. The most preferred resection techniques for diminutive (≤5 mm), small (6–9 mm), and benign-looking intermediate (10–19 mm) nonpedunculated polyps were cold forceps polypectomy, hot snare polypectomy, and endoscopic mucosal resection (EMR), respectively, in both the scenario- and image-based questionnaires. For benign-looking large (≥20 mm) nonpedunculated polyps, EMR and endoscopic submucosal dissection (ESD) were preferred in the scenario- and image-based surveys, respectively. In case of malignant nonpedunculated polyps, EMR and ESD were preferred for intermediate-sized and large lesions, respectively, according to the scenario-based survey. However, ESD was preferred in both intermediate-sized and large malignant nonpedunculated polyps according to the image-based survey. Trainee endoscopists, endoscopists working in referral centers, and endoscopists in the colorectal cancer–prevalent countries were independently associated with preference of cold snare polypectomy for removing small polyps.ConclusionsThe polypectomy practice patterns of Asian endoscopists vary, and cold snare polypectomy was not the most preferred resection method for polyps <10 mm in size, in contrast to recent guidelines.
