Comparative Study
Robot-assisted minimally invasive esophagectomy is equivalent to thoracoscopic minimally invasive esophagectomy.
The use of the surgical robot has been increasing in thoracic surgery. Its three-dimensional view and instruments with surgical wrists may provide advantages over traditional thoracoscopic techniques. Our initial experience with thoracoscopic robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer was compared with our traditional thoracoscopic minimally invasive esophagectomy (MIE) approach for esophageal cancer. ⋯ No differences in age, sex, race, body mass index, or preoperative radiotherapy or chemotherapy between the groups were observed. No significant differences in operative time, blood loss, number of resected lymph nodes, postoperative complications, days of mechanical ventilation, length of intensive care unit stay, or length of hospital stay were also observed. In this short-term study, RAMIE was found to be equivalent to thoracoscopic MIE and did not offer clear advantages.

Reflux of gastroduodenal contents and delayed gastric emptying are the most common and serious problems after esophagectomy with gastric reconstruction. However, attempts to reduce the above symptoms, surgically as well as non-surgically, had no or limited effect. To address this issue, we performed retrosternal gastric reconstruction with duodenal diversion plus Roux-en-Y anastomosis (RY) in eight patients with thoracic esophageal cancer and compared the outcomes with control patients who underwent standard reconstruction. ⋯ Postoperative endoscopic examination showed neither reflux esophagitis nor residual gastric content in the RY group. Quality of life assessed by the Dysfunction After Upper Gastrointestinal Surgery-32 questionnaire postoperatively was significantly better in the RY group than in the non-RY group for 'decreased physical activity,''symptoms of reflux,''nausea and vomiting,' and 'pain.' The results of this pilot study suggest that gastric reconstruction with duodenal diversion plus RY seems effective in improving both the reflux and delayed gastric emptying. The benefits of this procedure need to be further assessed in a large-scale, randomized controlled trial.

Comparative Study
Long-term outcomes following neoadjuvant chemoradiotherapy in patients with clinical T2N0 esophageal squamous cell carcinoma.
The optimal treatment for patients with local esophageal cancer (cT2N0 disease) has not yet been defined. We sought to determine whether neoadjuvant chemoradiotherapy (CRT) can improve prognosis compared with direct esophagectomy in this patient group. Between 1994 and 2005, patients with cT2N0 esophageal squamous cell carcinoma who underwent either neoadjuvant CRT or surgery as first-line treatment were retrospectively reviewed. ⋯ Despite the high pathological complete response (pCR) rate of 37% after neoadjuvant CRT, routine neoadjuvant CRT did not translate into better survival compared to direct surgery (5-year DSS: 39% vs. 68%, P= 0.17). The dramatic survival difference between pCR and non-pCR patients (5-year DSS: 85% vs. 4%, P < 0.001) accounts for these unsatisfactory results. In our series, the administration of neoadjuvant CRT to patients with clinical stage T2N0 esophageal squamous cell carcinoma did not significantly improve outcomes compared with direct esophagectomy.

Ankaferd Blood Stopper (ABS) is an herbal extract that enhances mucosal healing. The aim of this study was to investigate the efficacy of ABS on the healing of the esophagus and prevention of stricture development after esophageal caustic injuries in rats. The study included 50 rats. ⋯ Biochemical tests other than albumin and creatinine were comparable among the groups. Treatment with ABS prevents inflammation, scar formation, weight loss, and mortality in esophageal caustic injuries. Additional studies to evaluate the clinical benefits of ABS in esophageal caustic injury are recommended.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of laparoscopic anterior 180° partial versus 360° Nissen fundoplication: 5-year results.
Anterior partial fundoplication (AF) has been popularized by a lower risk of mechanical side effects. The question then emerges whether anterior partial wrap has a similar antireflux effect with Nissen fundoplication (NF). We therefore conducted a randomized study to compare the long-term outcome of anterior fundoplication with NF. ⋯ For 96 patients followed up more than 5 years, gastroesophageal reflux symptoms were well controlled in 81 patients (84.38%); the mean DeMeester scores in the AF group decreased from 106.89 ± 14.12 to 12.67 ± 3.14 and in the NF group from 109.51 ± 17.98 to 10.81 ± 2.65, and the esophagitis was ameliorated visibly. Moreover, there were significantly fewer patients in the AF group who complained of flatulence. Compared with NF, anterior 180° partial fundoplication is an effective treatment of gastroesophageal reflux and associates with fewer postoperative adverse effects.
