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.

The volume-outcome relationship has been validated previously for surgical procedures and cancer treatments. However, no studies have longitudinally compared the relationships between volume and outcome, and none have systematically compared laparoscopic cholecystectomy (LC) surgery outcomes in Taiwan. This study purposed to explore the relationship between volume and hospital treatment cost after LC. ⋯ Analysis using a hierarchical linear regression model and propensity score found an association between high-volume hospitals and surgeons and hospital treatment cost in LC patients. Moreover, the significant factors associated with hospital resource utilization for this procedure include age, gender, comorbidity, hospital type, hospital volume, and surgeon volume. Additionally, analysis of the treatment strategies adopted at high-volume hospitals or by high-volume surgeons may improve overall hospital treatment cost.

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.

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).

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.
