Plasma from the second and third weeks after minimally invasive colorectal resection (MICR) has high levels of the proangiogenic proteins VEGF and angiopoietin 2 and also stimulates, in vitro, endothelial cell (EC) proliferation and migration, which are critical to wound and tumor angiogenesis. Soluble vascular cell adhesion molecule-1 (sVCAM-1) stimulates EC chemotaxis and angiogenesis. The impact of MICR on blood levels of sVCAM-1 is unknown. This study's purpose was to determine plasma sVCAM-1 levels after MICR in colorectal cancer (CRC) patients. ⋯ MICR for CRC is associated with a persistent increase in plasma sVCAM-1 levels during the first month. This sustained increase may promote angiogenesis and stimulate the growth of residual tumor cells early after surgery.

Several studies have evaluated use of local anesthetic, specifically, administration of intraperitoneal anesthetic, during laparoscopic general surgery and gynecologic operations, with varying results. There have been no studies to determine the role of local anesthetic in laparoscopic colorectal surgery. This study evaluates the efficacy of subcutaneous and intraperitoneal anesthetic in reducing postoperative pain following common laparoscopic colorectal procedures, in patients managed with enhanced recovery care pathways. ⋯ Use of local anesthetic does not influence postoperative opioid requirements or patients' subjective report of pain following laparoscopic colorectal procedures managed within enhanced recovery care pathways.

Diagnosis and management of conjoined twins are constantly evolving. New imaging techniques provide important anatomic details and help in planning the separation procedure. Despite these technological advances, however, the complex arrangement of conjoined organs is somewhat difficult to interpret, leaving unresolved questions at time of surgery. The authors present a video demonstrating laparoscopy as an adjunct in the preoperative planning of separation of ischiopagus tripus conjoined twins as well as illustrating the complex anatomy in a combination of video, drawings, and radiologic imaging. To date, this is the first time that laparoscopy has been used in preoperative assessment of conjoined twins. ⋯ Diagnostic laparoscopy is a useful tool in evaluation of ischiopagus tripus conjoined twins. It is an important adjunct to preoperative studies in preparing for an expeditious and safe separation procedure.

Whether bilateral total extraperitoneal (TEP) inguinal hernia repair is associated with worse outcomes than unilateral TEP continues to be a matter of debate. This study aimed to compare different outcomes of large cohorts of patients undergoing bilateral versus unilateral TEP. ⋯ This is the first population-based analysis in the literature to compare different outcomes in a prospective cohort of more than 6,500 patients undergoing bilateral versus unilateral TEP. Although the rates for intraoperative and surgical postoperative complications were slightly higher for the patients undergoing bilateral TEP repair, the absolute differences were small and of minor clinical relevance. Bilateral TEP repair is associated with a minimal increase in operating time and similar LOS, general postoperative complications, and conversion rates. Therefore, for patients with bilateral inguinal hernia, a simultaneous endoscopic approach represents an excellent therapeutic option.

Minimally invasive esophagectomy (MIE) is a feasible technique that has been shown to be safe for the treatment of esophageal cancer. Chylothorax remains a challenging and potentially life-threatening postoperative complication of MIE. In this retrospective series, we evaluated the results of preventive intraoperative thoracic duct ligation in patients who underwent video-assisted thoracoscopic esophagectomy for cancer. ⋯ The results of this study suggest that thoracic duct ligation during video-assisted thoracoscopic esophagectomy for cancer is an effective and safe method for prevention of postoperative chylothorax.
