OBJECTIVE: Easy and safe methods of fascia closure are needed in order to reduce the risk for trocar site hernias without affecting procedure time significantly. Here we present a method for port site closure using heat induced collagen denaturation. MATERIAL AND METHODS: Controlled heat-induced collagen denaturation was applied to laparoscopic trocar sites in living porcine animal models. These were compared to control trocar sites which were left open. Port sites were evaluated visually at days 14 and 28 after the procedure, and both visually and pathologically at post-procedural day 42...

The lymph node status of patients with endometrial cancer is known to be a crucial determinant for the prognosis of the disease. It also provides the indication for further adjuvant treatment. The staging of endometrial cancer by surgery has been a controversial issue for more than 30 years. The significant complication rate after lymphadenectomy and the development of minimally invasive surgery have led to the use of sentinel lymph node (SLN) mapping. In the present review, we present the development of surgical staging procedures in patients with endometrial cancer and summarize the recently expanding body of published literature on the subject...

We report on a 69-year-old man with locally-advanced left maxillary sinus cancer who underwent treatment with intra-arterial chemoradiotherapy. Angiography showed that the main feeding arteries were the left maxillary artery and the ophthalmic artery, arising from the internal carotid artery. Due to acute branching of the ophthalmic artery, conventional microcatheters could not be inserted. Using a steerable microcatheter, we were able to repeatedly administer chemoradiotherapy via the ophthalmic artery. The tumor has mostly disappeared after intra-arterial chemoradiotherapy, and the patient is still alive two years after treatment...

Hysteroscopy and hysteroscopic myomectomy in general have low complication rates. Two patients underwent hysteroscopic myomectomy for prolapsing submucous myomas after UAE. The onset of prolapsing myoma occurred at varying times between completion of UAE and myomectomy, resulting in bacteremia for both patients. In Case 1, the patient recovered with intravenous antibiotic treatment. However, the patient in Case 2 had status improvement after undergoing an abdominal myomectomy, explorative laparotomy for removal of a necrotic myoma...

Commercially available laparoscopic instruments are not designed for female surgeons. We redesigned the endoscopic flexible head purse-string suture instrument for improved use by female surgeons. The weight, total length, and diameter of the swing head handle and clump handle were reduced (786 to 565 g, 715 to 700 mm, 70 to 50 mm, and 30 to 25 mm, respectively). Stroke of the slide for firing and release of the lever was reduced from 92 to 83 mm. This is the first step toward an ergonomic surgical device that considers physical differences related to sex...

BACKGROUND: We focused on the availability of an omnidirectional camera and head-mount display (HMD). If the laparoscope is an omnidirectional camera, captured images are sent to the HMD worn by the operator in real time. The operator can thus view the image as they like without moving the camera and obtain a 360° view intuitively. However, the surgical system that can be used for actual laparoscopic operations has not yet been developed. In this study, we aimed to show that an omnidirectional camera and HMD would be useful in laparoscopic surgery...

In the era of the novel coronavirus (COVID-19) pandemic, we critically appraised the literature by means of a systematic review on surgical education and propose an educational curriculum with the aid of available technologies. We performed a literature search on 10 May 2020 of Medline/PubMed, Embase, Google Scholar and major journals with specific COVID-19 sections. Articles eligible for inclusion contained the topic of education in surgery in the context of COVID-19. Specific questions we aimed to answer were: Is there any difference in surgical education from pre-COVID-19 to now? How does technology assist us in teaching? Can we better harness technology to augment resident training? Two-hundred and twenty-six articles were identified, 21 relevant for our aim: 14 case studies, three survey analyses, three reviews and one commentary...

INTRODUCTION: Minimally invasive image-guided interventions have changed the face of procedural medicine. For these procedures, safety and efficacy depend on precise needle placement. Needle targeting devices help improve the accuracy of needle placement, but their use has not seen broad penetration. Some of these devices are costly and require major modifications to the clinical workflow. In this article, we developed a low-cost, disposable, and easy-to-use angulation tracking device, which was based on a redesigned commercial passive needle holder...

BACKGROUND: The Corona virus disease 2019 (COVID-19) pandemic has affected surgical practice around the world. While several abdominal emergencies can be managed effectively and safely using minimally invasive surgery (MIS), the safety of using MIS amid the COVID-19 pandemic has been debated. MIS, including laparoscopy and robotic surgery, is considered an aerosol-generating procedure and some recent research demonstrated possible spread of the virus through aerosol. This review assessed the available evidence on the safety of MIS in the COVID-19 era, explored the possible precautions to be taken when using MIS to prevent exposure of the operating team to infection, and highlighted the recommendations of several surgical societies in this regard...
