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...

Occult bladder injury may sometimes go unrecognized during tension-free vaginal tape (TVT) procedures. We report a case of occult intraperitoneal bladder injury that occurred during a TVT procedure. There was no sign of bladder perforation on the initial cystoscopy, which was performed just after the insertion of the trocar. Signs of general peritonitis appeared after the patient started to voi...

BACKGROUND Recently, 25-gauge vitrectomy has become more popular. However, most still perform the surgery in pediatric patients without the use of the trocars and cannulas as in adult vitrectomies. METHODS We described a simple modification using adult 25-gauge cannulas and 270-silicone watzke sleeves, enabling these instruments to be used in pediatric cases. The sleeve is cut into segments o...

This paper reports a case of small bowel occlusion due to the herniation of an ileal ansa at the site of the insertion of a 12-mm trocar. A 28-year-old obese female patient underwent laparoscopic surgery for gastric bypass, the skin incisions of the trocar insertion sites were closed with absorbable sutures. Small bowel occlusion occurred on post-operative day 6 and the patient again underwent ...

BACKGROUND Open appendectomy is still the most common method of treating appendicitis. Laparoscopic procedures for removal of the appendix by the "in" technique as an alternative to conventional appendectomy have gained wide popularity, but have been criticized for their technical difficulty and high cost. We assessed the safety and efficacy of the laparoscope-assisted appendectomy (the two-tro...

INTRODUCTION Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS Nin...

surgery (NOTES) is a promising technique especially for cholecystectomy. During the last 2 years the combined transvagi− nal and transumbilical approach without visible scars [1] became a real alternative to standard four−trocar cholecystectomy in several institutions [2 ±4]. However, clearly this method cannot be used in men, and there might be psychological or cultural barriers preventing wom...
