predictors for failure of stent treatment for benign esophageal perforations- a single center 10-year experience

AIM:To investigate possible predictors for failed selfexpandable metallic stent(SEMS)therapy in consecutive patients with benign esophageal perforationrupture(EPR).METHODS:All patients between 2003-2013 treated for EPR at the Karolinska University Hospital,a tertiary referral center,were studied with regard to initial management with SEMS.Patients with malignancy as an underlying cause and those with anastomotic leakages were excluded.Sealing of the perforation with a covered SEMS was the primary strategy whenever feasible.Stent therapy failure was defined as a radical change of treatment strategy due to uncontrolled mediastinitis,which in this setting consisted of emergency esophagectomy with end-esophagostomy or death as a consequence of the perforation and subsequent uncontrolled sepsis.Patient and lesion characteristics were analyzed and are presented as median and interquartile range.Possible predictors for failed stent therapy were analyzed with uni-variate logistic regression,while variables with P<0.2 were further analyzed with multi-variate logistic regression.RESULTS:Of the total number of 48 patients presenting with EPR,40 patients(83.3%)were treated with SEMS at the time of admission,with an intention to heal the perforation.Twenty-three patients had Boerhaave’s syndrome(58%),16 had an iatrogenic perforation(40%)and 1 had external trauma to the esophagus(3%).The total in-hospital mortality,including the cases that had other initial treatments(n=8),was10.4%and 7.5%among those who were subjected to the SEMS-based strategy.In 33 of the 40 patients(82.5%)who were treated with stent,the EPR healed without further change in treatment strategy.Patients classified as treatment success received a SEMS at a median time of 1(1-1)d after the actual EPR,compared to 3(1-10)d among those where the initial treatment failed,P=0.039 in uni-variate analysis and P=0.052 in multi-variate analysis.No other significant factors emerged,indicating an increased risk for failure.Six of 7 patients,where stent treatment of the defect failed,underwent an emergency esophagectomy with end esophagostomy and one patient died.CONCLUSION:SEMS as an upfront therapeutic strategy seems to be a successful concept,when applied to an unselected group of patients with EPR.     

Impact of subcarinal dissection on short-term outcome and survival following esophagectomy

Background

The purpose of this study was to investigate the impact of subcarinal dissection on short-term outcomes and survival after esophagectomy in patients with thoracic esophageal squamous cell carcinoma.

Methods

Patients without subcarinal dissection were matched randomly to patients with subcarinal dissection in a 1:1 ratio according to 5 baseline variables (gender, pathologic stage, tumor location, histologic grade, and surgical approach) that may have major impacts on short-term outcomes and survival after esophagectomy in patients with thoracic esophageal squamous cell carcinoma. Preoperative clinical characteristics, short-term outcomes, and survival after esophagectomy of the 2 groups were compared.

Results

There were 128 patients included in each group. Blood loss, postoperative pleural drainage volume, and the incidences of postoperative complications and pulmonary complications in the nondissection group were significantly less than in the dissection group. The comparison of overall survival curves and disease-free survival curves between the 2 groups showed no significant difference (P > .05).

Conclusions

Subcarinal dissection might be futile for patients with thoracic esophageal squamous cell carcinoma.

Esophagectomy in patients with prior percutaneous endoscopic gastrostomy tube placement

Background

The impact of preoperative percutaneous endoscopic gastrostomy (PEG) tube placement in patients undergoing esophagectomy is uncertain.

Methods

A retrospective review was performed in consecutive patients who underwent esophagectomy. Patients were divided into groups based on whether or not they had preoperative PEG placement.

Results

One hundred seventeen patients were studied, 102 without (PEG−) and 15 with PEG+ before PEG tube placement. The overall morbidity and mortality rates were 38% and 3%, respectively. The use of a gastric conduit was similar between groups (94% PEG− vs 87% PEG+, P = .27), and the presence of a PEG before PEG tube placement was not prohibitive in any case. Anastomotic leak rates were similar between groups (11% PEG− vs 15% PEG+, P = .65), and there were no leaks from previous PEG sites.

Conclusion

It appears that preoperative PEG tube placement has no adverse effect on the performance of esophagectomy and may be considered in highly selected patients with poor nutritional status.     

Copper-deficiency anemia after esophagectomy: A pitfall of postoperative enteral nutrition through jejunostomy

INTRODUCTION

Copper deficiency leads to functional disorders of hematopoiesis and neurological system. There have been some reports of copper deficiency occurring to the patients on enteral nutrition through a jejunostomy in long-term-care hospitals. However, it is extremely rare to find patients with copper deficiency several months after esophagectomy, regardless of enteral nutrition through the jejunostomy. To the best of our knowledge, this is the first case report of a patient who experienced copper-deficiency anemia after esophagectomy and subsequent enteral nutrition through the jejunostomy.

PRESENTATION OF CASE

A 73-year-old man presented with pulmonary failure after esophagectomy for esophageal cancer with video-assisted thoracoscopic surgery, and needed long-term artificial ventilator support. Nutritional management included enteral nutrition through a jejunostomy from the early postoperative period. Copper-deficiency anemia was detected 3 months postoperatively; therefore, copper supplementation with cocoa powder was performed, and both serum copper and hemoglobin levels subsequently recovered.

DISCUSSION

Copper-deficiency anemia has already been reported to occur in patients receiving enteral nutrition in long-term care hospitals. However, this is the first case report of copper deficiency after esophagectomy despite administration of standard enteral nutrition through the jejunostomy for several months.

CONCLUSION

It is extremely rare to find copper-deficiency anemia several months after esophagectomy followed by enteral nutrition through the jejunostomy. However, if anemia of unknown origin occurs in such patients, copper-deficiency anemia must be considered among the differential diagnoses.     

A case of primary malignant melanoma of the esophagus with long-term survival

Primary malignant melanoma of the esophagus is uncommon, and its prognosis is poor compared to that of cutaneous malignant melanoma. Here we describe a case of primary malignant melanoma of the esophagus with a long-term survival. A 52-year-old woman received an upper gastrointestinal endoscopy and an upper gastrointestinal series for a dull back pain and dysphagia. A pigmented polypoid tumor in the esophagus was discovered and diagnosed pathologically as a malignant melanoma on the biopsied specimen. After effective chemotherapy with cisplatin (CDDP), the patient underwent surgical operation. A subtotal esophagectomy with three-field lymph node dissection was performed through a right thoracotomy. No distant metastasis including liver and lung was found, and histopathological examination revealed no lymph node metastasis. Postoperatively, six courses of chemotherapy with CDDP were performed. The patient has been alive without any problems for more than 11 years postoperatively.
