Purpose A major concern with sublobar resection (SR) for non–small-cell lung cancer (NSCLC) is high local recurrence (LR). Adjuvant brachytherapy may reduce LR This multicenter randomized trial compares SR to SR with brachytherapy (SRB). Patients and Methods High-risk operable patients with NSCLC ≤ 3 cm were randomly assigned to SR or SRB. The primary end point was time to LR, where LR included recurrence at the staple line (local progression), in the primary tumor lobe away from the staple line, and in ipsilateral hilar nodes. The trial was designed to have a 90% power to detect a hazard ratio (HR) of 0.315 in favor of SRB, using a one-sided type I error rate of 0.05 with a sample size of 100 eligible patients in each arm. Results Two hundred twenty-four patients were randomly assigned; 222 patients were evaluable for intent-to-treat analysis. Median age was 71 years (range, 49 to 87 years). No differences were found in baseline characteristics. Median follow-up time was 4.38 years (range, 0.04 to 5.59 years). There was no difference in time to LR (HR, 1.01; 95% CI, 0.51 to 1.98; log-rank P = .98) or in the types of LR. Local progression occurred in only 17 (7.7%) of 222 patients. In patients with potentially compromised margins (margin < 1 cm, margin-to-tumor ratio < 1, positive staple line cytology, wedge resection, nodule size > 2.0 cm), SRB did not reduce LR, although trends favored the SRB arm. This was most marked in 14 patients with positive staple line cytology (HR, 0.22; P = .24). Three-year overall survival rates were similar for patients in the SR (71%) and SRB (71%) arms (P = .97). Conclusion Brachytherapy did not reduce LR after SR. This finding may have been related to closer attention to parenchymal margins by surgeons participating in this study.

Objectives although video-assisted thoracoscopic surgery for pulmonary resection appears to be associated with more favorable postoperative outcomes than thoracotomy, no reports have discussed its benefit at subsequent reoperative pulmonary resection. Methods between January 2000 and December 2009, 144 patients underwent reoperative pulmonary resections for benign and malignant nodules at the Mayo Clinic, Rochester. Their data were evaluated retrospectively. Twenty-three (16%) patients had prior video-assisted thoracoscopic surgery, and 121 (84%) had undergone a prior open thoracotomy. Intraoperative and short-term postoperative outcomes were analyzed and compared between the two groups, using the chi-square test or Mann-Whitney test. Results overall reoperative mortality was 1.38% and morbidity was 49.3%. Intraoperative factor analysis showed that the prior video-assisted thoracoscopic surgery group more often underwent anatomical resection ( p = 0.0011) and showed a tendency towards a lower conversion rate from video-assisted thoracoscopic surgery to thoracotomy at reoperative pulmonary resection ( p = 0.051). Short-term postoperative outcomes showed that the prior video-assisted thoracoscopic surgery group had a significantly lower morbidity rate ( p = 0.013), significantly shorter hospital stay ( p = 0.002), and a tendency for a shorter duration of chest tube drainage ( p = 0.09). Conclusion our results suggest that prior video-assisted thoracoscopic surgery may lead to improved postoperative outcomes at subsequent reoperative pulmonary resection. Video-assisted thoracoscopic surgery may be favored for future potential reoperative pulmonary resections.

AbstractBackgroundBloating, flatulence, early satiety, and dysphagia resolve in more than 90% of patients early after fundoplication. Gastric dysfunction can persist, however, and a small number of patients develop severe gastric dysfunction (gastroparesis). Management of gastroparesis after antireflux procedures is generally conservative, but gastroparesis can become refractory to medical therapy. The aim of this study was to assess the role of gastric resection in the management of the unusual patient with severe postfundoplication gastric dysfunction.MethodsFrom January 1990 to October 2010, a total of 5,129 gastric resections were performed at our institution. From this cohort, we identified nine patients with postfundoplication gastric dysfunction managed with gastric resection. Clinical records were reviewed retrospectively for preoperative evaluation, perioperative course, and long‐term outcomes.ResultsOver 20 years, nine patients were treated with gastric resection for debilitating gastric dysfunction after antireflux surgery. Seven of the nine patients were female; the median preoperative body mass index was 25 kg/m2 (18–31 kg/m2). Median follow‐up was 23 months (1–97 months). Preoperatively, five patients required enteral feeding. Postoperatively, although there were no deaths, one patient required operative drainage of a subphrenic abscess, one developed temporary respiratory failure, and one was readmitted for partial small bowel obstruction. Six of the nine patients maintain their nutrition orally, but three are maintained with enteral nutrition. Only two patients are subjectively asymptomatic.ConclusionsOutcomes after gastric resection for postfundoplication gastric dysfunction are poor, with three of the nine patients requiring supplemental nutrition and seven of the nine having persistent symptoms.
