Preliminary study on the application of an umbrella-like abdominal wall-lifting device in gasless laparoscopic surgery.

UNLABELLED: Abstract Background: In laparoscopic surgery with CO2 pneumoperitoneum, serious complications often occur for elderly patients and those who undergo long operations. These complications mainly include respiratory and circulatory system changes. In patients with tumors, release of free tumor cells into the abdominal cavity is believed to be possible. Gasless laparoscopic techniques can avoid these complications of CO2 pneumoperitoneum. Currently, the main shortcoming of gasless laparoscopic techniques is inadequate operative space. Because of this shortcoming, gasless techniques have not been widely applied in clinical practice. MATERIALS AND METHODS: We herein describe a new technique of gasless laparoscopic cholecystectomy in pigs using a self-designed umbrella-like abdominal wall-lifting device. This device lifts up the anterior abdominal wall by opening the umbrella leaf in the abdominal cavity. RESULTS: Five pigs underwent laparoscopic cholecystectomy using this technique. The operation times were 85, 40, 28, 21, and 24 minutes. The corresponding bleeding volumes were 11, 20, 5, 2, and 8 mL. CONCLUSIONS: These preliminary outcomes suggest that the umbrella-like abdominal wall-lifting technique is safe and feasible in gasless laparoscopic surgery and can provide sufficient exposure of the operative field. Further study in the form of randomized controlled trials is needed to investigate the advantages of this new technique.

Teaching experience in Science of Acupuncture and Moxibustion : the advantage of "training the techniques of acupuncture and moxibustion before introducing meridians and acupoints" / 中国针灸

In term of four aspects, named "getting the familiarity", "turning to the positive action", "conquering the fear emotion" and "bringing the practice into play", the authors state that the teaching pattern, "training the techniques of acupuncture and moxibustion before introducing meridians and acupoints" can vividly introduce the classical content of meridians and acupoints in the Part One of Science of Acupuncture and Moxibustion, exclude the repeatability of the content and improve the teaching quality. This teaching pattern enables the students mastering the techniques of acupuncture and moxibustion before the practice and laying a good foundation for learning meridians and acupoints. The authors put forward the good suggestion of the teaching course arrangement of Science of Acupuncture and Moxibustion to benefit the teaching reform.

Laparoscopy-insisted vaginoplasty with peritoneum in patients with androgen insensitivity syndrome / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the technique and therapeutic effect of laparoscopy-insisted vaginoplasty with peritoneum in patients with androgen insensitivity syndrome.</p><p><b>METHODS</b>From May. in the Fifth People' s Hospital of Shenzhen. The therapeutic effect was retrospectively analyzed.</p><p><b>RESULTS</b>Laparoscopy-insisted vaginoplasty was successfully completely with peritoneum in patients with androgen in 4 cases. Ileumtivity segyndroment was used instead of peritoneum in one case. Open operation was not adopted in any cases. The ectopic testicles were removed during operation in 4 cases. The average operation time and bleeding volume was 60 min and 20 ml, respectively. Rectum, bladder and urethra were not injured in any case. The average vaginal length was 9 cm (range 8-10 cm) 21-28 days after operation. 6 months after operation, the surface of reconstructed vagina was smooth, ruddy and flexible, with satisfactory anatomical and functional results. Normal sexual activity was achieved in 2 cases.</p><p><b>CONCLUSIONS</b>Laparoscopy-insisted vaginoplasty with peritoneum could be used for female patients with androgen insensitivity syndrome. The ectopic testicles should be removed. Estrogen supplement and psychological guide after operation are also important.</p>
