There has been no research on the clinical outcomes of secondary self-expandable metal stent (SEMS) placement after initial stent migration. Therefore, this study aimed to assess the clinical outcomes of secondary SEMS placement after initial stent migration compared to the outcomes of secondary SEMS placement done for reasons other than migration and identify factors predictive of long-term outcomes. ⋯ Our data showed that secondary colorectal SEMS after stent migration is safe and effective. Moreover, the sustained clinical success of the secondary stent following migration was dependent on the outcomes of the first stent.

The use of self-expandable metal stents (SEMS) for the treatment of malignant colorectal obstruction is increasing. However, results of risk factors for its complications are inconsistent. This study aimed to examine the clinical effectiveness of the procedure as well as the complications and risk factors associated with the complications. ⋯ Although SEMS in patients with malignant colorectal obstruction is effective both as palliative therapy and as a bridge to surgery, one-third of patients experienced complications. Severity of obstruction and stent type can influence outcomes.

Esophageal leiomyomas are the most common benign tumors of the esophagus. Surgical enucleation is warranted for symptomatic patients. Thoracoscopic enucleation is the preferable approach for being less invasive by avoiding the discomfort and complications associated to larger thoracic incisions. The purpose of this study was to review our experience with enucleation of esophageal leiomyoma using a prone-position thoracoscopy technique. ⋯ Thoracoscopic enucleation of esophageal leiomyoma is a feasible, simple, and safe procedure. Thoracoscopy in the prone position with CO2 insufflation allows the use of usual technique of intubation and also provides optimal operative field. The advantages of the thoracoscopic approach are less postoperative discomfort and lower risk of complications from open thoracotomy (especially pulmonary).

Gastrectomy remains the mainstay of curative treatment for gastric cancer, yet it is associated with significant postoperative mortality. The laparoscopic approach has been introduced in an attempt to improve surgical outcomes. This study examines the uptake of laparoscopic gastrectomy in England and quantifies postoperative mortality and morbidity following gastrectomy for cancer. ⋯ LG is increasingly being performed in England. Postoperative morbidity and mortality of LG is similar to that of OG, but it is associated with a shorter hospital stay. Data from randomised controlled trials evaluating long term survival and patients' reported outcomes are essential before the final judgement on the value of LG in the management of gastric cancer.

Comparative Study
A propensity score-matched case-control comparative study of laparoscopic and open extended (D2) lymph node dissection for distal gastric carcinoma.
Technical proficiency at laparoscopic D2 lymph node dissection (LND) is essential for extending the use of laparoscopic surgery beyond the treatment of early gastric cancer (EGC). The aim of this study was to evaluate the technical and oncological feasibility of laparoscopic distal gastrectomy (LDG) with D2 LND for distal gastric cancer. ⋯ Laparoscopic D2 LND for distal gastric cancer is technically safe and feasible compared with ODG. A prospective randomized trial is warranted to evaluate long-term oncological outcomes in advanced gastric carcinoma.
