Objective To explore the minimal invasiveness and practability of combined video-assisted thoracic surgery (VATS) with two trocars and endoscopic ultrasonography (EUS) in the treatment of esophageal leiomyoma. Methods Between February 2007 and February 2012, we retrospectively analysed the clinical data of 166 patients who underwent various surgeries for the treatment of esophageal leiomyoma. Among them, 62 received routine thoracotomy (group A), 49 accepted conventional VATS surgery with three trocars (group B), and 55 underwent combined VATS surgery with two trocars and EUS (group C). Then, we summarized the clinical indexes of patients in all the three groups for further comparative analysis. Results There was no significant difference among the three groups in age, gender, and lesion location, origin level and size (P > 0.05). There were significant differences between group A and C in blood loss, surgery time, intraoperative localization, postoperative incision pain, hospitalization expenses, length of hospital stay, fasting time, pulmonary infection, and the complications during the follow-up (P < 0.05). There were significant differences between group C and B in blood loss, surgery time, intraoperative localization, fasting time and pulmonary infection (P < 0.05). Conclusion Combined VATS surgery with two trocars and EUS is safe, minimally invasive, thorough with few complications, which is worthy of clinical promotion.
Objective To investigate the expression and clinicopathological features of fumarate hydratase (FH) in multiple leiomyoma of the uterus. Methods Relevant clinicopathological data of patients with multiple leiomyoma of the uterus diagnosed pathologically between September 1, 2018 and August 31, 2019 were collected from the Department of Pathology of West China Second University Hospital. The morphology, FH protein expression and prognosis of FH negative patients were observed. Results A total of 900 patients were included. Among them, there were 825 cases of nonatypical leiomyomas, 36 cases of leiomyoma with bizarre nuclei, 34 cases of cellular leiomyoma and 5 cases of mitotically active leiomyoma. A total of 69 patients with negative FH expression were included, with an average age of (37.28±8.22) years. Among them, there were 43 cases of nonatypical leiomyomas, 19 cases of leiomyoma with bizarre nuclei, 6 cases of cellular leiomyoma, and 1 cases of mitotically active leiomyoma. At low magnification, staghorn shaped blood vessels, alveolar pattern edema, palisade distribution of smooth muscle cells and bizarre nuclei smooth muscle cells could be seen in patients with negative FH expression. At high magnification, cytoplasmic eosinophilicglobules andeosinophilic nucleolus surrounded by a halo could be seen in patients with negative FH expression. Among the 69 cases with negative FH expression, 60 cases (86.96%, 60/69) were followed up. All patients survived, of which 24 cases (40%, 24/60) recurred. Conclusion Immunohistochemically, the marker FH for multiple leiomyoma of the uterus is helpful to improve the identification of FH deficient leiomyoma in clinical work as well as early diagnosis in hereditary leiomyomatosis renal cell cancer syndrome.
【摘要】 目的 探討子宮頸巨大平滑肌瘤在其診斷及治療上的特殊性。 方法 對2007年10月-2010年3月收治的11例子宮頸巨大平滑肌瘤患者的臨床資料進行分析，對其發病率，診斷和手術治療進行評價。 結果 11例子宮頸巨大平滑肌瘤中黏膜下2例，腹膜后9例。術前9例出現誤診，其中誤診為盆腔包塊5例，子宮體肌瘤3例，子宮肉瘤1例。6例行經腹子宮全切加雙附件切除，2例行經腹子宮切除術，1例行經腹肌瘤挖除術，1例行經陰道肌瘤摘除術，1例行經腹肌瘤挖出加宮頸殘端切除術。 結論 子宮頸巨大平滑肌瘤由于其位置的特殊性，尤其是凸向腹膜后的肌瘤，由于盆腔器官被擠壓，使盆腔解剖結構發生改變，術前易被誤診。且手術過程中易出現損傷及出血，因此術前估計充分，術中仔細認清各器官解剖關系，可有效地減少術中損傷和控制出血。【Abstract】 Objective To investigate the particularity of diagnosis and treatment for giant uterine cervical leiomyoma. Methods We analyzed the clinical data of 11 patients with giant uterine cervical leiomyoma who were admitted in our hospital from October 2007 to March 2010. The incidence, diagnosis and surgical treatment of the disease were evaluated. Results Of the 11 cases, nine were retroperitoneal leiomyoma and two were submucous leiomyoma. There were nine misdiagnosed cases before operation, including five diagnosed as pelvic mass, one as uterine sarcoma and three as uterine corpus leiomyoma. Six patients underwent abdominal hysterectomy and bilateral salpingo-oophorectomy; two underwent abdominal hysterectomy; one underwent abdominal myomectomy; one underwent transvaginal myomectomy; and one underwent abdominal myomectomy with excision of cervical stump. Conclusion The giant uterine cervical leiomyoma is easily misdiagnosed preoperatively due to its special anatomic site. A good example is the retroperitoneal leiomyoma in which the pelvic anatomic structure is changed because of the extrusion of the tumor on other pelvic organs. Furthermore, injuries and bleeding often happen during the operation. Consequently, sufficient preoperative assessment and clearly identifying regional anatomical relations can effectively reduce the damage and bleeding during the operation.
Abstract: Objective To explore the outcomes of videoassistedthoracoscopic surgery (VATS) in the treatment of esophageal leiomyoma. Me thods [WTBZ] We reviewed and analyzed the clinical data of 87 patients with esophageal leiomyoma treated with VATS in Changhai Hospital of Second Military Medical University between June 2002 and January 2009. [WTHZ]Results [WTBZ]Videoassisted thoracoscopic leiomyoma enucleations was performed in 80 patients, whilea conversion to minithoracotomy was required in 7 others. All procedures werecompleted smoothly and the postoperative recovery was uneventful, without mortality or severe complications. The patients were drinking liquids from postoperative day 1 and were eating a normal diet from day 3. All patients were pathologically diagnosed with leiomyoma after operation. Followups of 6 months to 6.5 years (mean: 3.8 years) found no recurrence. [WTHZ] Conclusion [WTBZ]Videoassisted thoracoscopic enucleation can be the first choice for esophageal leiomyomas derived from lamina propria. Patients with esophageal leiomyomas of diameter gt;1.0 cm should be treated with VATS .
Objective To improve the knowledge of pulmonary benign metastasizing leiomyoma.Methods A case of pulmonary benign metastasizing leiomyoma diagnosed in the First Affiliated Hospital of Nanjing Medical University was analyzed.Results A 32-year-old woman suffered from chest stuffiness,heavy pant and weakness after myomectomy in amonth. Chest CT showed miliary shadowwas diffused in both sides of her lungs, but serumtumor marker was normal. When the chest CT result did not change significantly after four-week’s anti-tuberculosis treatment, the patient accepted lung biopsy by thoracoscopic surgery. HE staining showed that the tumor cells had characteristics of smooth muscle cell differentiation.Immunohistochemical staining showed a low proliferation index of tumor cells, which did not indicate theexistence of pulmonary malignant tumor. Smooth muscle actin ( SMA) and desmin as the specific markers of smooth muscle, estrogen receptor ( ER) and progesterone receptor ( PR) were all bly positive, which was the characteristic of pulmonary benign metastasizing leiomyoma. The patient was given the anti-estrogen tamoxifen for 3 months.Without radiological evidence of disease development and further distant metastasis,the patient had been followed up. Conclusions Pulmonary benign metastasizing leiomyoma is a rare disease which can occur in any age group, particularly prevalent among late childbirth women. All patients have uterine leiomyoma history and/ or myomectomy operation, often associated with uterine metastasis, which commonly occurs in lung.
Objective To develop a novel methylene blue staining technique to localize small esophageal leiomyomas (<1.5 cm) and evaluate its feasibility. Methods Between January 2013 and October 2016, 9 patients with small esophageal leiomyomas (<1.5 cm) underwent thoracoscopic enucleation in Tongji Hospital. There were 5 males and 4 females with an average age of 51 years. We preoperatively injected 0.5–1.0 ml methylene blue in the submucosa adjacent to the tumors under the guidance of gastroscope. Then, we transferred the patients to the operating room. Results Staining was successful in 9 patients. The unstained tumor was exposed after the blue-stained mediastinal pleura and overlying muscle were incised longitudinally during video-assisted thoracoscopic surgery via one utility port. No abnormalities were detected in the esophageal mucosa. No major complications, such as esophageal leakage or esophageal diverticulum occurred. Conclusion Endoscopic methylene blue staining is safe and feasible for localizing small esophageal leiomyomas during video-assisted thoracoscopic surgery via one utility port. This method will enable enucleation precise and easy.
