Endoscopic management of gastrointestinal smooth muscle tumor

AIM: To systematically evaluate the efficacy and safety of endoscopic resection of gastrointestinal smooth muscle tumors (SMTs, including leiomyoma and leiomyosarcoma) and to review our preliminary experiences on endoscopic diagnosis of gastrointestinal SMTs. METHODS: A total of 69 patients with gastrointestinal SMT underwent routine endoscopy in our department. Endoscopic ultrasonography (EUS) was also performed in 9 cases of gastrointestinal SMT. The sessile submucosal gastrointestinal SMTs with the base smaller than 2 cm in diameter were resected by "pushing" technique or "grasping and pushing" technique while the pedunculated SMTs were resected by polypectomy. For those SMTs originating from muscularis propria or with the base size ≥ 2 cm, ordinary biopsy technique was performed in tumors with ulcers while the "Digging" technique was performed in those without ulcers. RESULTS: 54 cases of leiomyoma and 15 cases of leiomyosarcoma were identified. In them, 19 cases of submucosal leiomyoma were resected by "pushing" technique and 10 cases were removed by "grasping and pushing" technique. Three cases pedunculated submucosal leiomyoma were resected by polypectomy. No severe complications developed during or after the procedure. No recurrence was observed. The diagnostic accuracy of ordinary and the "Digging" biopsy technique was 90.0% and 94.1%, respectively. CONCLUSION: Endoscopic resection is a safe and effective treatment for leiomyomas with the base size ≤2 cm. The "digging" biopsy technique would be a good option for histologic diagnosis of SMTs.     

Is it possible to differentiate gastric GISTs from gastric leiomyomas by EUS？

AIM： To evaluate the ultrasonography （EUS） features of gastric gastrointestinal stromal tumors （GISTs） as compared with gastric leiomyomas and then to determine the EUS features that could predict malignant GISTs.
METHODS： We evaluated the endoscopic EUS features in 53 patients with gastric mesenchymal tumors confirmed by histopathologic diagnosis. The GISTs were classified into benign and malignant groups according to the histological risk classification.
RESULTS： Immunohistochemical analyses demonstrated 7 leiomyomas and 46 GISTs. Inhomogenicity, hyperechogenic spots, a marginal halo and higher echogenicity as compared with the surrounding muscle layer appeared more frequently in the GISTs than in the leiomyomas （P 〈 0.05）. The presence of at least two of these four features had a sensitivity of 89.1% and a specificity of 85.7% for predicting GISTs. Except for tumor size and irregularity of the border, most of the EUS features were not helpful for predicting the malignant potential of GISTs. On multivariate analysis, only the maximal diameter of the GISTs was an independent predictor. The optimal size for predicting malignant GISTs was 35 mm. The sensitivity and specificity using this value were 92.3% and 78.8%, respectively.
CONCLUSION： EUS may help to differentiate gastric GISTs from gastric leiomyomas. Once GISTs are suspected, surgery should be considered if the size is greater than 3.5 cm.

Combination conventional endoscopy and endoscopic ultrasound can differentiate between esophageal granular cell tumors and leiomyomas

Esophageal leiomyomas and granular cell tumors (GCTs) are the 2 most common subepithelial tumors found in the esophagus. We attempted to differentiate the 2 tumors using endoscopic findings and endoscopic ultrasound (EUS) features. Between December 2008 and June 2021, a total of 38 esophageal GCTs and 11 esophageal leiomyomas originating from the muscularis mucosa were selected. Clinical characteristics and endoscopic features were retrospectively reviewed. Although esophageal GCTs are mainly located in the lower third of the esophagus (81.6%), esophageal leiomyomas are mainly located in the upper third of the esophagus (45.5%). Broad-based (84.2%, P = .002) and whitish-to-yellowish color changes (97.4%, P < .001) are significant endoscopic features of esophageal GCTs. The echogenicity of esophageal leiomyoma was similar to that of proper muscle echogenicity. However, the echogenicity of esophageal GCTs was hyperechoic compared to that of the proper muscle layer (90.0% vs 9.1%, respectively, P < .001). EUS revealed a clearer hyperechoic epithelial lining in the esophageal leiomyoma than in esophageal GCTs (100% vs 26.7%, respectively, P < .001). The 5 endoscopic factors (location of the lower third, broad base, whitish-to-yellowish color, hyper-echogenic, and unclear demarcated hyperechoic epithelial line) were counted to differentiate esophageal GCTs from esophageal leiomyomas. Tumors with 3 or more endoscopic factors were all esophageal GCTs. The characteristic endoscopic and EUS features of esophageal GCTs were broad-based, whitish-to-yellowish colored subepithelial tumors located in the lower third of the esophagus and hyperechoic tumor with an unclear demarcated hyperechoic epithelial line. A combination of these features can predict esophageal GCTs before endoscopic resection.     

Endoscopic alcohol injection therapy of giant gastric leiomyomas: an alternative method to surgery

Leiomyomas are the most common benign mesenchymal tumours of the upper gastrointestinal tract. They rarely cause symptoms when they are smaller than 5 cm in diameter. Observation with repeated endoscopies is recommended in asymptomatic patients with small lesions. Surgical resection remains the main therapy option for symptomatic and complicated patients. The treatment of esophageal leiomyoma has been enhanced by improvements in diagnostic and therapeutic endoscopic techniques; however, the same cannot be said for gastric leiomyoma management. The present article describes the management of two cases involving giant gastric leiomyomas that were  successfully treated using endoscopic injection of alcohol. To the authors' knowledge, the present study is the first report of the treatment of such hemorrhagic gastric tumours using this alternative and low-cost technique. Endoscopic local ethanol injection may be the treatment of choice in carefully selected patients with hemorrhagic leiomyomas of the upper gastrointestinal tract.     

Esophageal leiomyoma: experience from a single institution

Esophageal leiomyomas are rare. We report the clinicopathologic features of one of the largest series of esophageal leiomyomas from a single institution. We retrospectively reviewed the Cleveland Clinic pathology database (1985–2010) for patients with a diagnosis of esophageal leiomyoma(s). Clinicopathologic features of 30 cases from 28 patients were analyzed. The group included 15 females and 13 males with a mean age at diagnosis of 56 years. These include 9 excisions, 9 esophagectomies, and 12 endoscopic biopsies. Only one partial esophagectomy was performed solely for a symptomatic 14‐cm leiomyoma; the remainder of the resections (n= 8) were for other indications, including esophageal cancer (Barrett's esophagus‐related adenocarcinoma and squamous cell carcinoma) and emergent esophageal perforation, with leiomyoma being an incidental finding. One patient (2.5%) had two synchronous leiomyomas (14 cm and 0.3 cm). Tumor size ranged from 0.1 to 14 cm (mean = 2.0 cm). Mean tumor size among symptomatic patients was 5.2 cm, as compared with 0.4 cm in asymptomatic patients. Dysphagia was the most common complaint in symptomatic patients (71.4%). Sixty‐nine percent of the tumors were located in the distal and middle thirds of the esophagus, with most (69.6%) arising from muscularis propria. Histologically, these tumors were composed of bland spindle cells with low cellularity, no nuclear atypia, or mitotic activity. Only one case (14 cm) showed focal moderate cellularity and nuclear atypia, with low mitotic activity (<1/10 high power field). Immunohistochemical studies showed tumor cells were positive for smooth muscle actin, and negative for CD34 and CD117. Follow‐up information was available for 22 patients (78.6%), and none had adverse events related to leiomyoma. In summary, esophageal leiomyoma is a rare benign tumor of the esophagus. Patients with larger tumors were more likely to have symptoms. The majority of the tumors were in the lower and mid‐esophagus, and arose from muscularis propria. These tumors behave in a clinically benign fashion.     

Diffuse esophageal leiomyomatosis with a pedunculated polyp

Although leiomyomas are the most common benign tumors of the esophagus, esophageal leiomyomatosis is a rare pathological entity, and pedunculated presentation is even rarer. A 61-year-old man was found, incidentally, to have an esophageal tumor on a survey of chest computed tomography (CT) examination for a pulmonary nodule. Endoscopy disclosed a pedunculated polyp covered by nearly normal esophageal mucosa, with surrounding annular extension of a submucosal elevation. Endoscopic ultrasonography (EUS) revealed a hypoechoic tumor, with a maximum diameter of 3cm originating from the thickened muscularis mucosa layer. The underlying muscularis propria layer was also prominently thickened. The polypoid lesion was then removed by endoscopic resection with wire-loop ligation, followed by snare electrocoagulation. The pathological diagnoses of the polyp and the surrounding submucosal lesions were both leiomyoma. Diffuse esophageal leiomyomatosis was suspected in this situation because of the characteristic pathological distribution. In this patient, the EUS findings corresponded well to the characteristic features of diffuse esophageal leiomyomatosis noted in previous reports, and this was of great help for the diagnosis, in addition to the endoscopic findings. This case report is presented with a particular focus on the problems associated with accurate diagnosis.

目的探讨无腹腔镜辅助的内镜全层切除术（EFR）治疗源于固有肌层的胃黏膜下肿瘤（SMT）的疗效和可行性。方法2007年7月至2009年8月经辅助检查和前期治疗明确诊断为起源于固有肌层的胃SMT患者20例,择期行全麻下EFR治疗：（1）黏膜下注射生理盐水,预切开肿瘤周围黏膜和黏膜下层,显露肿瘤;（2）采用内镜黏膜下剥离术（ESD）技术沿肿瘤周围分离固有肌层至浆膜层;（3）应用Hook刀沿肿瘤边缘切开浆膜;（4）胃镜直视下应用Hook、IT刀或圈套器完整切除包括浆膜在内的肿瘤;（5）应用金属夹缝合胃创面。结果20例源于固有肌层的胃SMT中,病灶位于胃底9例、胃体11例。EFR成功切除所有病变,完整切除率为100％,未使用腹腔镜辅助;EFR时间为60—145min,平均85min。切除肿瘤最大直径1．8～3．5cm,平均2．6cm;病理诊断为问质瘤13例、平滑肌瘤4例、血管球瘤2例、神经鞘瘤1例。术后无一例出现胃出血、腹膜炎体征及腹腔脓肿,术后3d造影无一例造影剂外漏和胃排空障碍。住院天数3～8d,平均5．5d。术后随访1～12个月,平均7个月,无一例病变残留或复发。结论EFR治疗源于固有肌层的胃SMT是安全、有效的,可以切除更深的胃壁肿瘤,并提供准确的病理诊断资料,它的开展可进一步扩大内镜治疗的适应证。     

超声内镜对消化道黏膜下肿物的诊断价值

目的评价超声内镜对消化道黏膜下肿物（SMT）的诊断价值。方法对378例胃肠镜检查过程中发现SMT的患者进一步行超声内镜检查,记录超声内镜下病变的形状、数量、起源层次,并对病变进行定性诊断。根据肿物切除术中实际所见统计超声内镜判断SMT形状、数量、起源层次的符合率,以切除标本病理学及免疫组织化学检查结果为金标准检验超声内镜定性诊断SMT的符合率。结果378例SMT中,平滑肌瘤（131例）最多见,多为低回声（87例）、回声均匀（119例）、起源于黏膜肌层（92例）;其次为胃肠道间质瘤（111例）,多为低回声（51例）或中低回声（51例）、回声均匀（78例）、起源于固有肌层（85例）;再次为类癌（50例）,内部回声均匀,多为低回声（36例）、起源于黏膜下层（27例）;还发现脂肪瘤45例,起源于黏膜下层,多为高回声（40例）、回声均匀（41例）;异位胰腺（19例）、神经鞘瘤（4例）、颗粒细胞瘤（4例）等相对少见。超声内镜对SMT的总体定性诊断符合率为78．6％（297／378）,瘤体的形状判断符合率为91．8％（347／378）,数量判断符合率为95．5％（361／378）,层次起源判断符合率为96．8％（366／378）。结论各种SMT在超声内镜下特点不一,虽然超声内镜检查可以显示肿物的回声、大小、起源以及与消化道管壁层次的关系,对于SMT的诊断、鉴别诊断及治疗方案的选择有重要的指导意义,但是仍有一定局限性。

Endoscopic ultrasonography for the diagnosis and selecting treatment of esophageal leiomyoma

Background and Aim: To investigate the clinical value of endoscopic ultrasonography (EUS) with miniature ultrasonic probes (MUP) for the diagnosis and treatment of esophageal leiomyoma. Methods: A total of 229 patients with esophageal leiomyoma, diagnosed using EUS, with 12‐MHz MUP and a double‐cavity electronic endoscope, were enrolled. The clinical characteristics of the patients were analyzed, and those who had therapeutic indications received endoscopic resection or surgical excision. Postoperative histological diagnostic results were compared with the preoperative diagnosis of EUS. All patients, including those with or without endoscopic resection or surgical excision were periodically followed up with EUS. Results: Of the 229 patients, 118 received endoscopic resection, and seven received surgical excision. Postoperative histology showed that 110 patients were completely consistent with the preoperative diagnosis of EUS, and the diagnostic accuracy of EUS was 88.6%. No treatment‐related complications occurred among the patients who received endoscopic resection or surgical excision, and no recurrence was observed during the follow‐up examinations. Conclusions: Esophageal leiomyoma is a benign tumor of the esophagus. EUS is a useful technique for the diagnosis of esophageal leiomyoma and for making treatment‐related decisions.

Clinical Evaluation of Endoscopic Ultrasonogrphy in Diagnosis of Submucosal Tumor of the Upper Alimentray Tract

Abstract: The usefulness and the problems of endoscopic ultrasonograpy (EUS) in the diagnosis of submucosal tumors (SMT) of the upper alimentary tract were evaluated in this study. EUS was carried out in 86 cases with SMT of the stomach. Tumors of 13 cases was confirmed histologically (leiomyoma in 7 cases, leiomyosarcoma in one, lipoma in 2, gastric cyst in one, aberrant pancreas in one and Schwannoma in one case). In only one out of 22 cases with SMT of the esophagus, the tumor was surgically resected and a pathological examination revealed leiomyoma EUS was useful in estimating the histological origin of SMT by observation of the relationship between the location of the tumor and each layer in the gastric or esophageal wall. However, it was imposible to differentiate leiomyoma from leiomyosarcoma in myogenic tumors through the echoic pattern of the tumor by EUS alone at the present time. EUS was also useful in distinguishing the cause of extragastric compression showing similar findings with SMT, which could not be clarified by X-ray or endoscopic examination. In fact, organs compressing the stomach were easily clarified by EUS. It was decided that EUS should be performed in all cases whenever there is any doubt of SMT existing after an X-ray or endoscopic examination.     

内镜下圈套结扎在治疗上消化道小平滑肌瘤中的应用

目的 探讨应用内镜下皮圈结扎的方法来治疗上消化道的小平滑肌瘤，并评价这种方法的安全性和疗效。方法 通过内镜、内镜超声及内镜超声下穿刺细胞学检查确定了59例上消化道小平滑肌瘤患者，共发现64处平滑肌瘤。在这64处平滑肌瘤中，50处为食管平滑肌瘤，12处为胃平滑肌瘤，2处为十二指肠平滑肌瘤。对所有平滑肌瘤进行皮圈套扎治疗，术后2周开始，每周做胃镜检查观察结扎处的变化，直至创面完全愈合。结果 64处病变中50处食管平滑肌瘤被完全去除，创面的平均愈合时间为3．1周。12处胃平滑肌瘤中9处被完全去除，其余3例由于结扎不彻底，仍有残余瘤组织，平均愈合时间为4.5周。2例十二指病变被完全去除，平均愈合时间4．5周。全部患者无一例发生出血、穿孔。结论 内镜下圈套结扎术是治疗上消化道小平滑肌瘤安全、有效的方法。
