Single trocar transanal endoscopic surgery (STTE) is a well-known technique for evaluation and management of rectal lesions in adults. We used an 11mm balloon trocar with a 10mm operative optic, introduced into the anal canal to excise a rectal lesion along with multiple rectal biopsies in a child. Rectal visibility was good with an ease to maintain the rectum insufflated.

In 1987, Mouret performed the first laparoscopic cholecystectomy changing surgical practice and it was mentioned by Rosen and Ponsky.1 Then the laparoscopic abdominal surgery increased and was common by the 1990s.2 The adoption of this new technique resulted new, specific operative complications. Incisional hernias at the site of entry of a trocar is a serious complication in laparoscopy,3 as m...

► We describe a new technique for robotic infrarenal para-aortic lymphadenectomy. ► This technique includes the new robotic trocar insertion sites. ► We perform the complete lymphadenectomy with a single docking procedure. ► This technique is feasible for complete lymphadenectomy in endometrial staging.

Since learning of the video-assisted thoracoscopic techniques in the treatment of thoracic diseases, we have encountered many problems and difficulties because of the limited trocar space and lack of suitable instrumentations. Since March 1992, we have found a simple and easier way to perform this procedure, that is, manipulating through the extended incisional wound without using a trocar. End...

For examining pig ovaries, which have complex structures, laparoscopy is a useful technique, but requires general anesthesia; therefore, it cannot be performed repeatedly within a short period of time. We report a transvaginal endoscopy-based technique for conducting ovarian examinations without general anesthesia. Sows were sedated in pig stalls. Using a colonoscope, the vaginal wall was punct...

INTRODUCTION The first videolaparoscopic nephrectomy in children was performed in 1992, and since then, little experience, and small series of pediatric patients have been reported. The technique, described by Clayman and accepted worldwide, requires the insertion of 4 or 5 trocars. Introduction of trocars is an important cause of complication in videolaparoscopic surgery. The authors report la...
