The use of intraoperative carbon dioxide (CO(2)) colonoscopy during a laparoscopic colon operation is becoming more common. Simultaneous intracolonic and intraabdominal CO(2) insufflation may result in significant physiologic changes, but in-depth physiologic effects have not been studied to date. This study aimed to evaluate the physiologic changes and the overall safety of simultaneous CO(2) laparoscopy and colonoscopy. ⋯ Simultaneous CO(2) colonoscopy and laparoscopy lead only to transient alterations in respiratory parameters that can be compensated. Based on these findings, simultaneous insufflation of CO(2) into the peritoneal cavity and the large bowel lumen during complex endoscopic procedures may be considered safe for most patients.

Laparoscopic distal pancreatectomy (LDP) is increasingly performed for lesions of the body and tail of the pancreas. We analyzed the clinical characteristics of the largest series of patients to date who underwent LDP at a single center, as well as their outcomes, to reassess the surgical paradigm for left pancreatic resection. ⋯ LDP is feasible, safe, and effective for the treatment of benign and low-grade malignant lesions of the pancreas. The increased use of LDP for left-sided pancreatic lesions, including malignant lesions, represents a paradigm shift from open distal pancreatectomy.

Case Reports
Laparoscopic repair of intrathoracic liver herniation after traumatic rupture of the diaphragm.
Right diaphragmatic hernia after abdominal trauma is a rare injury. Most patients can be asymptomatic, and the diagnosis may be delayed for several years. ⋯ The authors treated a young patient with transdiaphragmatic herniation of the right hepatic lobe and delayed diagnosis using a laparoscopic approach and accomplished a successful complete repair. The 6-month radiologic follow-up assessment confirmed good results.

Meta Analysis Comparative Study
A meta-analysis of randomized controlled trials of fixation versus nonfixation of mesh in laparoscopic total extraperitoneal inguinal hernia repair.
Mesh fixation during laparoscopic total extraperitoneal (TEP) inguinal hernia repair is still controversial. Although many surgeons considered it necessary to fix the mesh, some published studies supported elimination of mesh fixation. Therefore, a meta-analysis based on randomized controlled trials (RCTs) was conducted to compare the effectiveness and safety of fixation versus nonfixation of mesh in TEP. ⋯ Without increasing the risk of early hernia recurrence, the nonfixation of mesh in TEP appears to be a safe alternative that is associated with less costs, shorter operative time, and hospital stay for the selected patients. Further adequately powered RCTs are required to clarify whether mesh fixation is necessary for the patients with different types of hernias and larger hernia defects.

The Texas Association of Surgical Skills Laboratories (TASSL) is a nonprofit consortium of surgical skills training centers for the accredited surgery residency programs in Texas. A training and research collaborative was forged between TASSL members and Simbionix (Cleveland, OH, USA) to assess the feasibility and efficacy of a multicenter, simulation- and Web-based flexible endoscopy training curriculum using shared GI Mentor II systems. ⋯ The feasibility of sharing educational and training resources among institutions was demonstrated. Likewise, the concept of "mobile simulation" appears to be useful and effective, with three of the four institutions involved successfully in implementing the training curriculum during a fixed period. Additionally, subjects who completed the training demonstrated both subjective and objective improvements in flexible endoscopy skills.
