The potential effects of laparoscopic surgery on intra- and postoperative intraocular pressure (IOP) are not completely understood. Although prior studies have reported that pneumoperitoneum may increase IOP, it is not clear whether this increase is related to the effects of pneumoperitoneum or to the patient's position, such as the Trendelenburg position. This study aimed to evaluate the potential fluctuations of IOP during colorectal laparoscopic surgery in two groups of patients: those with and those without Trendelenburg positioning. ⋯ Standard pneumoperitoneum (≤14 mmHg) led to mild and reversible IOP increases. A trend was observed toward a greater IOP increase in patients with Trendelenburg positioning. Thus, the patient's position during surgery may represent a stronger risk factor for IOP increase than pneumoperitoneum-related intraabdominal pressure.

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).

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.

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.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of fibrin glue versus tacked fixation in laparoscopic groin hernia repair.
Preliminary studies have indicated clinical advantages of mesh fixation using fibrin glue in transabdominal preperitoneal groin hernia repair (TAPP) compared with tack fixation. The aim of this randomized double-blinded, controlled, clinical trial is to compare fibrin glue with tacks fixation of mesh during TAPP. ⋯ Fibrin glue compared with tacks fixation improved the early postoperative outcome after TAPP. The trial was registered at clinicaltrials.gov NCT01000116.
