  • Progress of Perioperative Management for Esophagectomy

    Abstract: Due to complicated procedures and severe trauma, esophagectomy still remains an operation with high mortality and morbidity. With the advancement of anesthetic and surgical technique, as well as perioperative management, the mortality and morbidity after esophagectomy decreased significantly in recent years. The optimal perioperative management, normalized and individualized treatment was of importance in preventing postoperative complications and decreasing mortality after esophagectomy. This review summarizes the current state of perioperative management for esophagectomy.

  • Surgical Treatment of Thoracic Outlet Tumors Via Posterior Thoracotomy

    Objective To introduce the procedure of thoracic outlet tumors removal through posterior thoracotomy and its efficacy. Methods Ten patients with thoracic outlet tumors underwent surgical treatment via posterior approach from June 2004 to June 2007. Five patients suffered from neurogenic tumors, 4 patients apical lung carcinomas, and 1 patient apicoposterior lung tumor. The skin incision was started superiorly lateral to the transverse process of 6th cervical vertebrae, carried downward a way between the medial border of the scapula and the posterior midline and was extended in a gentle arc below the inferior angle of the scapula to the posterior axillary line. The chest was entered and the tumor is removed through resecting the rib(2nd or 3rd rib) located at the lower edge of the tumor after the scapula had been pushed forward. Results There was no death in this group. Tumors in 9 patients were resected completely. Thoracotomy only was done in another patients as a result of tumor invading neighboring major organs. Shoulder and back pain in 3 of 4 patients was remitted postoperatively. Two patients with “dumbell” neurogenic tumors improved strength of lower limbs. Pain and abdominal wall reflex resumed in one patient and muscle strength of lower limbs increased to 4th grade from 2nd grade in another one. Two patients required thoracentesis because of complicating with pleural effusion. The mean followup period was 18 months (range 336). Seven of 10 patients still lead a normal life. Conclusion Posterior thoracotomy can provide an excellent approach to remove the thoracic outlet tumors safely and completely. 

  • 外科手术取食管异物15例

    目的探讨外科手术取食管异物的适应证及手术方法。方法采用外科手术摘除尖锐食管异物15例,其中颈段5例,胸段10例。5例颈段异物均合并脓肿,行脓肿切开引流同时取出异物;4例胸段异物摘除后施行改良食管腔内置管术;余6例取出异物后分层缝合食管切口。结果全组无死亡。4例施行食管腔内置管,术后1~2周中毒症状缓解,3~5周拔管后食管X线钡餐造影检查无穿孔或狭窄。1例切开食管取异物后发生右侧脓胸,术后第8d行脓胸廓清术及改良食管腔内置管,1个月后治愈;其余患者术后7~10d恢复经口进食。结论已穿透食管的金属异物和食管镜摘除易引起穿孔的尖锐异物应采用外科手术治疗,改良食管腔内置管对纵隔感染严重、无法修补的穿孔愈合是有帮助的。

  • Effect of Lung Volume Reduction Surgery on mRNA Expression Levels of Cytoskeletal Proteins in Diaphragmatic Muscle Tissues of Emphysematous Rabbits

    Objective To investigate the effect of lung volume reduction surgery (LVRS) on messenger RNA expression levels of cytoskeletal proteins in diaphragmatic muscle tissues of emphysematous rabbits. Methods A total of 40 rabbits were randomly divided into 4 groups (10 rabbits in each group) :normal control group, emphysema group, sham operation group and LVRS group. Rabbits in control group were intratracheally administered with 0.9% normal sodium, but those in other groups were intratracheally administered with 0.4% papain at the dose of 0.5 ml/kg and inhaled cigarette smoke to induce emphysema model. Then, rabbits in emphysema group were fed routinely, however, after median sternotomy , bilateral LVRS was performed in LVRS group but not in sham operation group. The mRNA expression levels of titin and nebulin in the diaphragmatic muscles of rabbits in each group were detected by reverse transcription-polymerase chain reaction(RT-PCR). Results Compared with control group, the mRNA expression levels of titin and nebulin in the rabbit diaphragm of emphysema groups and sham operation group decreased significantly (P〈0.01 ), so did those in LVRS group (P〈0.05). But it increased significantly in LVRS group compared with emphysema group and sham operation group (P〈0.05). Conclusion LVRS can increase the mRNA expression levels of titin and nebulin in diaphragmatic muscle tissues of emphysematous rabbits, which may be the associated mechanisms at the molecular level in restoring the functions of the emphysematous diaphragm by LVRS.

  • The Prevention of Stricture Formation with Esophageal Intraluminal Stenting in Patients with Corrosive Esophageal Burns

    Objective To introduce the technique of esophageal intraluminal stenting and assess its effect on the prevention of development of stenosis in patients with esophageal burns. Methods Thirty-three patients were admitted less than 3 weeks after ingestion of caustic agents. The second-or third-degree injuries were confirmed by esophogoscopy in all cases, but one with esophageal perforation at admission. Esophageal stenting was performed in all patients and these stents were kept in place for 4 to 6 months. Results There was no death in the series. All patients had a normal intake of food after removal of the stents, and stricture was not found on barium swallow test. Follow-up from 1 to 60 months five cases developed esophageal stenosis from 2 to 3 months after extracting the stents. One of them responded to esophageal bougienage, the remaining 4 patients required esophageal reconstruction and took a normal diet postoperatively. The other 28 patients have a normal diet after the stent removal. Conclusion The esophageal intraluminal stenting is able to prevent the formation of stricture in the aftermath of esophageal burns and its effect will be enhanced plus administering isoniazid.

  • Analysis of Postoperative Complications and Cause of Death for Carcinoma of Esophagus

    Objective To analyse postoperative complications and cause of death for carcinoma of esophagus. Methods A retrospective study was undertaken for data of 2 085 patients with esophageal carcinoma from 1963 to 2003, the patients were divided into group A (332 cases,1963-1983), group B(727 cases,1984-1993) and group C (1 026 cases,1994-2003) by time. The postoperative complications and cause of death were analysed. Results Resectability rate, incidence rate of postoperative complications and hospital mortality were 90.84%(1 894/2 085), 11.61% (242/2 085) and 1.82% (38/2 085) respectively. Main complications were pulmonary complications (3.93%,82/2 085),anastomotic leak (3.12%,59/1 894), and cardiovascular disease (1.29%,27/2 085). Resectability rate of group B and group C were higher than that of group A, incidence rate of postoperative complications and hospital mortality of group B and group C were lower than that of group A. Resectability rate of group C were higher than that of group B, incidence rate of postoperative complications except pulmonary complications and hospital mortality of group C were lower than those of group B. Conclusions Pulmonary complications and anastomotic leak are main postoperative complications and cause of hospital death for carcinoma of esophagus, they are decreasing in recent years because of the progress of anesthetic,surgical technique and perioperative management.
