A rare case of chest wall lipoma growing into the pleural cavity: a case report.

BACKGROUND: Several cases of lipoma in unusual locations in the thorax have been reported. Appropriate surgical treatment depending on the location and shape is often required. CASE PRESENTATION: We herein report an extremely rare case of a chest wall lipoma growing into the pleural cavity. The tumor was successfully removed without damaging the capsule by a combination of direct and thoracoscopic approaches. CONCLUSIONS: Chest wall lipomas growing into pleural cavity can be successfully treated by a combination of direct and thoracoscopic approaches.

Endoscopic Vacuum Therapy in the Management of Postoperative Leakage After Esophagectomy.

BACKGROUND: Postoperative leakage after esophagectomy is associated with significant life-threatening complications. Recently, endoscopic vacuum therapy (EVT) was introduced and has been successfully used as a new treatment option. The purpose of this study was to evaluate the safety and efficacy of EVT for the management of postoperative leakage after esophagectomy. METHODS: A total of 22 patients were treated with either intraluminal or intracavitary EVT for the management of postoperative leakage from May 2012 to April 2018. The location of leakage was intrathoracic in 17 patients and cervical in five patients. The outcomes of EVT were analyzed retrospectively. RESULTS: Complete postoperative leakage closure was achieved in 19 of 22 patients. The median duration of EVT application was 14 days (range 2-103), and a median number of three EVT systems (range 1-14) were used. In 19 patients who were successfully managed with EVT, oral feeding was possible a median of 15 days after the first day of treatment. There were no cases of mortality related to postoperative leakage. CONCLUSIONS: EVT is a well-tolerated and effective therapeutic option for the treatment of various types of postoperative leakage after esophagectomy.

Effect of Adjuvant Chemotherapy after Complete Resection for Pathologic Stage IB Lung Adenocarcinoma in High-Risk Patients as Defined by a New Recurrence Risk Scoring Model.

PURPOSE: We conducted a retrospective analysis to determine if adjuvant chemotherapy prolongs overall survival in patients with pathologic stage IB lung adenocarcinoma who had undergone complete resection and were defined as high-risk by a newly developed recurrence risk scoring model. MATERIALS AND METHODS: Patients who underwent curative resection for stage IB lung adenocarcinoma were analyzed with a newly developed recurrence risk scoring model and divided into a low-risk group and a high-risk group. The patients in the high-risk group were retrospectively divided into two groups based on whether they underwent adjuvant chemotherapy or observation. Recurrence-free survival and overall survival were compared between these two groups. RESULTS: A total of 328 patients who underwent curative resection between 2000 and 2009 were included in this study, of whom 110 (34%) received adjuvant chemotherapy and 218 (67%) underwent observation without additional treatment. According to our risk model, 167 patients (51%) were high-risk and 161 (49%) were low-risk. The 5-year recurrence-free survival rates and overall survival were 84.4% and 91.5% in low-risk patients and 53.9% and 74.7% in high-risk patients (p < 0.001). In high-risk patients, the 5-year overall survival rates were 77% among patients who underwent observation and 87% among those who underwent adjuvant chemotherapy (p=0.019). CONCLUSION: Adjuvant chemotherapy prolonged overall survival among high-risk patients who had undergone complete resection for stage IB lung adenocarcinoma.
