The incidence of incisional hernia has not decreased despite the use of laparoscopy for colon resections. The objective of this study is to evaluate the impact of the incision used for specimen extraction on the incidence of incisional hernia after laparoscopic colectomy. ⋯ There is a high incidence of symptomatic incisional hernia after midline specimen extraction in laparoscopic colectomy, which negatively impacts cosmesis. The risk of hernia may be lower with the use of a transverse or Pfannenstiel incision for specimen extraction.

Electromagnetic coupling can occur between the monopolar "Bovie" instrument and other laparoscopic instruments without direct contact by a phenomenon termed antenna coupling. The purpose of this study was to determine if, and to what extent, radiofrequency energy couples to other common laparoscopic instruments and to describe practical steps that can minimize the magnitude of antenna coupling. ⋯ Commonly used laparoscopic instruments couple monopolar radiofrequency energy without direct contact with the active electrode, a phenomenon that results in heat transfer from a nonelectrically active instrument tip to adjacent tissue. Practical steps to minimize heat transfer resulting from antenna coupling include reducing the monopolar generator power setting and avoiding of parallel bundling of the telescope and active electrode cords.

Laparoscopic colectomy for colon cancer has become a standard of care, with a number of publications highlighting its safety, improved postoperative recovery, and excellent oncologic outcomes. Complete mesocolic excision, recently reemphasized, is associated with superior oncologic outcomes, although this has not been discussed for laparoscopic surgery. A laparoscopic approach was performed for right colon cancer using a four-trocar technique. ⋯ The median overall survival time was 38 months (IQR, 23-54 months). The embedded didactic video demonstrates a straight laparoscopic complete mesocolic excision with high-vessel ligation for a patient who had a right colon cancer. Laparoscopic right complete mesocolic excision is a safe and effective procedure associated with excellent 3-year oncologic outcomes and accelerated postoperative recovery.

Multicenter Study Controlled Clinical Trial
The LINX® reflux management system: confirmed safety and efficacy now at 4 years.
Sphincter augmentation with the LINX® Reflux Management System is a surgical option for patients with chronic gastroesophageal disease (GERD) and an inadequate response to proton pump inhibitors (PPIs). Clinical experience with sphincter augmentation is now available out to 4 years. ⋯ Sphincter augmentation with the LINX Reflux Management System provided long-term clinical benefits with no safety issues, as demonstrated by reduced esophageal acid exposure, improved GERD-related quality of life, and cessation of dependence on PPIs, with minimal side effects and no safety issues. Patients with inadequate symptom control with acid suppression therapy may benefit from treatment with sphincter augmentation.

Randomized Controlled Trial Comparative Study
Transvaginal cholecystectomy versus single-incision laparoscopic cholecystectomy versus four-port laparoscopic cholecystectomy: a prospective cohort study.
This report describes the first prospective cohort study comparing transvaginal cholecystectomies (TVC) with single incision laparoscopic cholecystectomies (SILC) and four-port laparoscopic cholecystectomies (4PLC). ⋯ Transvaginal cholecystectomy is a safe and well-tolerated procedure with statistically significantly less pain at 1 and 3 days after surgery, with a faster return to work but longer operative times compared with single incision and four-port laparoscopic cholecystectomy.
