Thoracoscopic removal of neurogenic mediastinal tumors: technical aspects

Background: Thoracoscopy is fast becoming the standard approach for the removal of neurogenic mediastinal tumors. However, there are risks for adjacent nervous structures (stellate ganglion, spinal cord). The aim of this study was to review the technical features of this approach.Methods: Between December 1999 and January 2003, nine patients underwent thoracoscopic resection of a mediastinal neurogenic tumor at our hospital. Five of these patients were asymptomatic with incidentally found tumor; the other four patients had compression-related syndromes. Two tumors had developed in the superior sulcus, and one had a spinal canal component (dumbell-type tumor).Results: Thoracoscopic dissection was possible in all cases. In one patient, resection of the tumor was performed via a combined neurosurgical and thoracoscopic approach. Seven tumors were benign nerve sheath tumors (schwannoma), and 2 were nerve cell tumors (ganglioneuroma). The postoperative course was uncomplicated in all patients.Conclusion: The thoracoscopic resection of mediastinal neurogenic tumors is technically easy, except for bulky tumors of the superior sulcus and dumbbell tumors, which require a combined thoracoscopic and neurosurgical approach.     

Hepatic resection in 128 patients: a 24-year experience

The records of 128 patients who underwent hepatic resection at the Cleveland Clinic Foundation between 1960 and 1984 were reviewed. Sixty patients (47%) had major resections and 68 patients (53%) had wedge or segmental resections. One hundred five patients had malignant tumors; 29 were primary liver tumors and 78 were metastatic (61 from a colorectal primary). Twenty-three patients had benign hepatic tumors. The overall operative mortality rate was 7% (7.6% for malignant tumors and 4.3% for benign lesions). Survival rate after resection of a hepatocellular carcinoma (22 patients) at 3, 5, and 10 years was 50%, 33%, and 12%. Survival rate after resection of colorectal metastases at 3, 5, and 10 years was 44%, 28%, and 21%. Overall survival was better for patients who were less than 56 years of age (p = 0.003) and for patients with no tumor at the line of resection (p less than 0.001). In patients with colorectal metastases, survival after wedge or segmental resection was better than after a major anatomic resection (p = 0.004). In these patients, the number or size of the metastases, the time interval between resection of the primary tumor and of the hepatic metastases, and/or the presence of mesenteric lymph node metastases were not significant. Most patients with primary malignant tumors require major hepatic resection. Patients with benign tumors and metastatic colorectal carcinomas require resection only to the extent that the tumor is sufficiently encompassed.

Primary tracheal tumors: experience with 14 resected patients.

OBJECTIVE: Primary tracheal tumors are rare. Management includes interventional endoscopy, surgery and radiotherapy. METHODS: Between 1987 and 1996, 14 patients treated by resection and reconstruction of the trachea and bifurcation for primary tracheal tumors were retrospectively analyzed. RESULTS: The most common histological finding was adenoid cystic carcinoma (n=7), followed by a squamous cell carcinoma (n=2), a mucoepidermoid carcinoma (n=2), a carcinoid tumor (n=1) and two benign tumors (xanthogranuloma, pleomorphic adenoma). Various reconstruction techniques were used and one prosthesis was implanted. Eight of the patients required preoperative Nd-YAG laser recanalisation. Six were treated by postoperative external beam radiotherapy, in three cases combined with endoluminal brachytherapy. Two major postoperative wound-healing impairment at the anastomosis occurred. Four minor wound-healing disorders were successfully treated by interventional endoscopy. Two patients died postoperatively with mediastinitis respectively with bilateral pneumonia. A local recurrence was observed in only two cases. At the last follow-up in January 1998, nine patients were still alive. We observed five long-term survivors (>6 years) with an adenoid cystic carcinoma or mucoepidermoid carcinoma. CONCLUSIONS: Extensive segmental resection of the trachea is the treatment of choice for primary malignant and occasionally for benign tracheal tumors. Interventional endoscopy is a part of modern tracheal surgery.     

Resection and reconstruction of the retrohepatic vena cava in combination with liver resections

Liver resection combined with the resection and reconstruction of the vena cava represents the only potential curative therapy for malignant hepatic tumors with invasion of the vena cava. We performed a liver resection with segmental replacement of the retrohepatic vena cava by synthetic grafts in 29 patients. In three cases, the additional presence of central involvement of all three hepatic veins required ex situ tumor resection. Four patients underwent a simultaneous exstirpation of the primary tumor (kidney or suprarenals). The remaining hepatic veins were reimplanted into the graft in three cases, and in two cases the renal veins were reimplanted. There was no perioperative mortality. A distal arteriovenous fistula was not applied. Five patients revealed postoperative transient liver insufficiency, requiring temporary dialysis in three cases. Two of these patients developed a transient multiorgan failure with the need of mechanical ventilation. 18 patients died during the course of follow-up, 17 of these cases due to recurrent metastases of the primary disease. Infection or thrombosis of the prosthetic vascular graft have not been observed. Beside tumor exstirpation, extended liver resection and concomitant vena cava replacement may prevent embolism as well as the obstruction of the vena cava with lower extremity swelling and the possibility of developing a Budd Chiari syndrome. We were able to achieve a long-term survival for surgically treated patients even in cases with advanced tumor stages.

Thoracoscopic resection of posterior neurogenic tumors

Video-assisted thoracic surgery (VATS) may be used for resection of posterior mediastinal tumors to avoid thoracotomy and shorten hospital stay. Between October 1990 and June 1998, 23 patients had VATS resection of posterior neurogenic tumors. The 14 females and 9 males ranged in age from 14 months to 70 years, with a median of 35 years. Operation time ranged from 30 to 120 minutes (median, 83), and intraoperative complications were limited to minor problems as well as conversion to thoracotomy to enhance complete tumor resection in four cases. Tumor pathology included nerve sheath origin (20) and autonomic ganglia (3). There was only one malignant schwannoma. Tumor size ranged from 0.7 to 13 cm in diameter. Median chest tube days was 1 day (range, 1-4), and hospital stay was 2 days (range, 1-9). Postoperative complications included transient paresthesia (three cases), ileus (two cases), pleural effusion (one case), and transient intercostal pain (one case). Posterior neurogenic tumors may be resected safely using video-assisted techniques. Conversion to thoracotomy to enhance complete resection is both possible and encouraged. The use of VATS seems to decrease hospital stay and minimize postoperative complications. In posterior neurogenic tumors without tumor extension to the spinal canal, VATS has become our preferred method for resection.     

Limited resection for duodenal gastrointestinal stromal tumors:Surgical management and clinical outcome

AIM:To analyze our experience in patients with duodenal gastrointestinal stromal tumors(GIST) and review the appropriate surgical approach.METHODS:We retrospectively reviewed the medical records of all patients with duodenal GIST surgically treated at our medical institution between 2002 and 2011.Patient files,operative reports,radiological charts and pathology were analyzed.For surgical therapy open and laparoscopic wedge resections and segmental resections were performed for limited resection(LR).For extended resection pancreatoduodenectomy was performed.Age,gender,clinical symptoms of the tumor,anatomical localization,tumor size,mitotic count,type of resection resectional status,neoadjuvant therapy,adjuvant therapy,risk classification and follow-up details were investigated in this retrospective study.RESULTS:Nine patients(5 males/4 females) with a median age of 58 years were surgically treated.The median follow-up period was 45 mo(range 6-111 mo).The initial symptom in 6 of 9 patients was gastrointestinal bleeding(67%).Tumors were found in all four parts of the duodenum,but were predominantly located in the first and second part of the duodenum with each 3 of 9 patients(33%).Two patients received neoadjuvant medical treatment with 400 mg imatinib per day for 12 wk before resection.In one patient,the GIST resection was done by pancreatoduodenectomy.The 8 LRs included a segmental resection of pars 4 of the duodenum,5 wedge resections with primary closure and a wedge resection with luminal closure by Roux-Y duodeno-jejunostomy.One of these LRs was done minimally invasive;seven were done in open fashion.The median diameter of the tumors was 54 mm(14-110 mm).Using the Fletcher classification scheme,3/9(33%) tumors had high risk,1/9(11%) had intermediate risk,4/9(44%) had low risk,and 1/9(11%) had very low risk for aggressive behaviour.Seven resections showed microscopically negative transsection margins(R0),two showed positive margins(R1).No patient developed local recurrence during follow-up.The one patient who underwent pancreatoduodenectomy died due to progressive disease with hepatic metastasis but without evidence of local recurrence.Another patient died in complete remission due to cardiac disease.Seven of the nine patients are alive disease-free.CONCLUSION:In patients with duodenal GIST,limited surgical resection with microscopically negative margins,but also with microscopically positive margins,lead to very good local and systemic disease-free survival.

Urgent indications for surgery in primary or secondary cardiac neoplasm

Ten patients underwent resection of primary or secondary cardiac tumor. Two-dimensional transthoracic echocardiography per se accurately located the endoluminal cardiac mass in nine patients, and transesophageal echocardiography demonstrated a right atrial tumor in the tenth case. The indications for urgent surgery included prior embolic events (3 cases), syncopal attacks (2) or echocardiographic evidence of a multilobulated mass (2 cases). The operative strategy was standardized for atrial tumors, but for malignant myocardial neoplasm both the anatomic site and the extent of tumor growth determined the surgical procedure. Histologic examination showed myxoma in seven cases, fibroma in one and metastases of malignant melanoma in two cases. The course after resection of endoluminal benign tumor was uneventful apart from transient atrial fibrillation in four cases. Follow-up echocardiography (after 4-28 months) showed no recurrent growth. In both cases of intracardiac metastases there was recurrence within 6 to 8 months after resection of the growth.
