Abstract
Methods
The surgical technique was described, pictured, and recorded. The surgery was performed in a tertiary hospital.
Results
During laparoscopic surgery, the specimen is resected from the surrounding tissues and contained in a specimen bag to prevent spillage. The edges of the bag are then pulled through the trocar site, and the specimen—protected by the bag—is removed. To facilitate the removal process and to prevent spillage, assistants will normally hold the edges of the bag during the process. To mitigate the need for assistants to hold the edges of the bag, we wrapped the pulled edges of the bag around a ring retractor, which is a plastic ring, to straighten the bag. This technique enabled the operator to remove the specimen without needing an assistant.
Laparoscopic surgery for benign gynecologic diseases consists of trocar insertion, tissue excision/repair, and specimen extraction. Specimen extraction can be challenging if the specimens are large or solid. For example, in a study of laparoscopic myomectomy, the mean specimen extraction time was 28 minutes, despite the use of a power morcellator [1]. During specimen extraction, the use of a specimen bag is recommended to prevent spillage.
Solo surgery is defined as an operation performed by the surgeon alone, without assistants. Lack of experienced assistants and advances in technology have promoted the adoption of solo surgery, and reports of its use in various fields have shown it to be feasible [2-5]. For example, in a study that included 25 solo surgeries for hernia repair, none of the procedures required an assistant [6]. In addition, in solo laparoscopic surgeries for benign gynecologic diseases, the tissue excision/repair step can be performed using a robotic uterine manipulator and a robotic laparoscope holder [5].
However, without assistants, a key issue is whether specimen extraction is possible. When we extract specimens, assistants pull the specimen bag and facilitate the extraction by straightening the bag; this helps in preventing spillage. If we can extract specimens without assistants, then the surgery can be performed completely solo from start to finish. In addition, we can reduce injuries associated with specimen extraction. For example, knife morcellation may injure assistants who are holding the specimen bag.
Herein, we report a technique that enables specimen extraction without the need for assistants. After the specimen is placed in the specimen bag, the edges of the bag are pulled through the trocar wound. The pulled edges of the bag are wrapped around a ring retractor, which is a plastic ring, to straighten the bag. By repeatedly turning the retractor inside out, the bag is straightened by the friction between the bag and retractor. Once the bag is straightened, the operator can extract the specimen alone. When the bag is loosened, the operator can additionally turn the retractor to re-straighten the bag.
By adopting this technique, specimens can be extracted alone, without assistants. One practical tip is to use a bag one size larger than one would normally use because extra length is required for wrapping around the retractor.
