The Cost

Abstract Background Technology currently used for surgical endoscopy was developed and is manufactured in high-income economies. The cost of this equipment makes technology transfer to resource constrained environments difficult. We aimed to design an affordable wireless endoscope to aid visualisation during rigid endoscopy and minimally invasive surgery (MIS). The initial prototype aimed to replicate a 4-mm lens used in rigid cystoscopy. Methods Focus was placed on using open-source resources to develop the wireless endoscope to significantly lower the cost and make the device accessible for resource-constrained settings. An off the shelf miniature single-board computer module was used because of its low cost (US$10) and its ability to handle high-definition (720p) video. Open-source Linux software made monitor mode (“hotspot”) wireless video transmission possible. A 1280 × 720 pixel high-definition tube camera was used to generate the video signal. Video is transmitted to a standard laptop computer for display. Bench testing included latency of wireless digital video transmission. Comparison to industry standard wired cameras was made including weight and cost. The battery life was also assessed. Results In comparison with industry standard cystoscope lens, wired camera, video processing unit and light source, the prototype costs substantially less. (US$ 230 vs 28 000). The prototype is light weight (184 g), has no cables tethering and has acceptable battery life (of over 2 h, using a 1200 mAh battery). The camera transmits video wirelessly in near real time with only imperceptible latency of < 200 ms. Image quality is high definition at 30 frames per second. Colour rendering is good, and white balancing is possible. Limitations include the lack of a zoom. Conclusion The novel wireless endoscope camera described here offers equivalent high-definition video at a markedly reduced cost to contemporary industry wired units and could contribute to making minimally invasive surgery possible in resource-constrained environments.

ObjectivesTo evaluate the current patterns of use of minimally invasive surgical procedures, including traditional, robotic-assisted, and single-port laparoscopy, by Society of Gynecologic Oncology (SGO) members and to compare the results to those of our 2004 and 2007 surveys.MethodsThe Society of Gynecologic Oncology members were surveyed through an online or mailed-paper survey. Data were analyzed and compared with results of our prior surveys.ResultsFour hundred six (32%) of 1279 SGO members responded. Eighty-three percent of respondents (n = 337) performed traditional laparoscopic surgery (compared with 84% in 2004 and 91% in 2007). Ninety-seven percent of respondents performed robotic surgery (compared with 27% in 2007). When respondents were asked to indicate procedures that they performed with the robot but not with traditional laparoscopy, 75% indicated radical hysterectomy and pelvic lymphadenectomy for cervical cancer. Overall, 70% of respondents indicated that hysterectomy and staging for uterine cancer was the procedure they most commonly performed with a minimally invasive approach. Only 17% of respondents who performed minimally invasive surgery performed single-port laparoscopy, and only 5% of respondents indicated that single-port laparoscopy has an important or very important role in the field.ConclusionsSince our prior surveys, we found a significant increase in the overall use and indications for robotic surgery. Radical hysterectomy or trachelectomy and pelvic lymphadenectomy for cervical cancer and total hysterectomy and staging for endometrial cancer were procedures found to be significantly more appropriate for the robotic platform in comparison to traditional laparoscopy. The indications for laparoscopy have expanded beyond endometrial cancer staging to include surgical management of early-stage cervical and ovarian cancers, but the use of single-port laparoscopy remains limited.

The single-port gasless laparoscopic surgical instrument is an international leading patented product in minimally invasive surgery. This paper first describes the composition and the usage of the shadowless retractor of the single-port gasless laparoscopy minimally invasive surgical instrument. Aim to meet the specific requirement arise in the minimally invasive surgery for the animal abdominal cavity, we first improve the existing shadowless lifting retractor. Then, this paper proposes and designs the double-light shadowless lifting retractor. The test has shown the designed double-light shadowless lifting retractor has satisfied the design requirement. The practical tests have been done and shown the viability and effectiveness of the proposed design approach.

Mediastinal Parathyroid

Inferior parathyroid adenomas in the mediastinum can be a troublesome cause for hypercalcaemia, requiring a full collar incision or, occasionally, a sternotomy. We report a case of a giant parathyroid adenoma in a 61-year-old woman on warfarin, which we excised via a minimally invasive transcervical approach after radiological localisation. The procedure was performed as a day case and, at six weeks, the patient had recovered fully with biochemical resolution of hypercalcaemia. This case demonstrates that focused transcervical excision of giant parathyroid adenomas is a viable option and should be considered prior to neck exploration or sternotomy.

Esophageal cancer is an uncommon but highly lethal disease. Surgical resection is the gold standard of treatment for early-stage disease. Traditional surgical approach entailed significant convalescence, hospital stay, and morbidity and mortality. Transhiatal esophagectomy (THE) involves blind dissection of the esophagus with minimal mediastinal lymphadenectomy. Integration of robotic surgery is an alternate platform for minimally invasive approach while maintaining safety and following oncologic principles. We review our technique for minimally invasive THE using robotic technology, demonstrating the safety and efficacy of robotic technology surgery. We present a retrospective review of a single surgeon's data of patients treated with robotic-assisted THE, with a chart review to evaluate pathology, adequacy of surgical resection, nodal harvest, and perioperative course. Robotic THE (rTHE) shows promise as a valid option for esophageal resection, including premalignant and advanced stages of cancer. Adequate transhiatal mediastinal nodal resection can be performed with the robot.
