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 observe the midterm haemodynamic manifestation of the home made C-L pugestrut tilting disc mechanical valve in aortic valve replacement, and to evaluate its function. Methods Twenty patients underwent aortic valve replacement over 5 years were collected and divided into two groups, the C-L pugestrut group （n=10）：aortic valve was replaced by home-made C-L pugestrut tilting disc mechanical valve（21mm）; Medtronic-Hall group （n=10）：aortic valve was replaced by Medtronic-Hall mechanical valve （21mm）. The peak transprosthetic gradients （△P）, mean transprosthetic gradients （△Pm）and effective orifice area（EOA） at rest were compared between two groups. Results At rest, △P of the C-L pugestrut group and Medtronic-Hall group were 11.63±3.23mmHg vs. 9. 78±3. 35mmHg; △Pm of the C-L pugestrut group and Medtronic-Hall group were 6. 25±2. 32 mmHg vs. 5.85±2.32mmHg： EOA of the C-L pugestrut group and Medtronic-Hall group were 1.07±0.17 cm2 vs. 1.25±0.27 cm2. There was no statistically significance in △P, △Pm and EOA between two groups（P〉0.05）. Conclusions The midterm haemodynamic results of the home-made C-L pugestrut tilting disc mechanical valve show that it has comparable haemodynamic results to those of Medtronic-Hall mechanical valve ,and it has well-done function. The home-made C-L pugestrut valve is one of the reliable mechanical heart valves.
ObjectiveTo investigate the clinical efficacy of minimally invasive Ivor-Lewis esophagectomy (MIILE) with reverse-puncture anastomosis. MethodsClinical data of the patients with lower esophageal carcinoma who underwent MIILE with reverse-puncture anastomosis in our department from May 2015 to December 2020 were collected. Modified MIILE consisted of several key steps: (1) pylorus fully dissociated; (2) making gastric tube under laparoscope; (3) dissection of esophagus and thoracic lymph nodes under artificial pneumothorax with single-lumen endotracheal tube intubation in semi-prone position; (4) left lung ventilation with bronchial blocker; (5) intrathoracic anastomosis with reverse-puncture anastomosis technique. Results Finally 248 patients were collected, including 206 males and 42 females, with a mean age of 63.3±7.4 years. All 248 patients underwent MIILE with reverse-puncture anastomosis successfully. The mean operation time was 176±35 min and estimated blood loss was 110±70 mL. The mean number of lymph nodes harvested from each patient was 24±8. The rate of lymph node metastasis was 43.1% (107/248). The pulmonary complication rate was 13.7% (34/248), including 6 patients of acute respiratory distress syndrome. Among the 6 patients, 2 patients needed endotracheal intubation-assisted respiration. Postoperative hemorrhage was observed in 5 patients and 2 of them needed hemostasis under thoracoscopy. Thoracoscopic thoracic duct ligation was performed in 1 patient due to the type Ⅲ chylothorax. TypeⅡ anastomotic leakage was found in 3 patients and 1 of them died of acute respiratory distress syndrome. One patient of delayed broncho-gastric fistula was cured after secondary operation. Ten patients with type Ⅰ recurrent laryngeal nerve injury were cured after conservative treatment. All patients were followed up for at least 16 months. The median follow-up time was 44 months. The 3-year survival rate was 71.8%, and the 5-year survival rate was 57.8%. ConclusionThe optimized MIILE with reverse-puncture anastomosis for the treatment of lower esophageal cancer is safe and feasible, and the long-term survival is satisfactory.
