AIM: Endoscopic surgery for acute subdural hematoma (ASDH) has recently been performed in elderly patients. Unlike other reported procedures, we used the endoscope's fixation device to ensure hemostasis because the surgeon can then use a surgical instrument with each hand. To date, there have no reports that prove lesser invasiveness or noninferiority of endoscopic surgery based on direct comparison with a large craniotomy. In this study, we investigated whether our endoscopic procedure was effective and safe...

PURPOSE: Laparoscopic common bile duct exploration (LCBDE) has been widely used to remove common bile duct (CBD) stones. However, surgery is not considered as the first treatment choice for elderly patients with CBD stones because of the potential risk of postoperative complications. This study aims to evaluate the safety and efficiency of LCBDE for elderly patients. METHODS: From April 2011 to October 2016, 265 consecutive patients underwent LCBDE. We performed a retrospective study and divided these patients into 2 groups...

BACKGROUND: The standard treatment of rectovaginal deep infiltrating endometriosis nodules (RVDIEN) consists in their surgical removal. RVDIEN are anatomically neovascularized. Indocyanine green (ICG) reveals vascularized structures when becoming fluorescent after exposure to near-infrared (NIR) light. This study aims to evaluate if fluorescence-guided surgery can improve the laparoscopic resection of RVDIEN, thus avoiding a rectal perforation. MATERIALS AND METHODS: Patients with a symptomatic RVDIEN, scheduled for a laparoscopic rectal shaving, were enrolled in the study...

OBJECTIVES: In recent years, video-assisted thoracoscopic surgery (VATS) has increasingly become the preferred technique for thoracic surgery. However, the inherent characteristics of the lungs as large, soft, slippery, and delicate creates difficulties for pulmonary surgery. In this article, we outline the development and assessment of a balloon-based organ retractor for VATS via collaboration between medical and engineering personnel. METHODS: A dry lab trial and accompanying questionnaire assessment were performed by a group of thoracic surgeons...

Successful multidisciplinary treatment of skull base pathology requires precise preoperative planning. Current surgical approach (pathway) selection for these complex procedures depends on an individual surgeon's experiences and background training. Because of anatomical variation in both normal tissue and pathology (eg, tumor), a successful surgical pathway used on one patient is not necessarily the best approach on another patient. The question is how to define and obtain optimized patient-specific surgical approach pathways? In this article, we demonstrate that the surgeon's knowledge and decision making in preoperative planning can be modeled by a multiobjective cost function in a retrospective analysis of actual complex skull base cases...

OBJECTIVE: To assess the prevalence of patients whose anatomy would be potentially amenable to percutaneous cholecystoenteric lumen-apposing metallic stents (LAMS) insertion from a population of acute cholecystitis patients. METHODS: Contrast-enhanced abdominal computed tomography images in 100 consecutive adult patients with acute cholecystitis were reviewed retrospectively. Feasibility of LAMS placement percutaneously or with endoscopic ultrasound guidance was defined as the presence of a straight and unobstructed trajectory from the skin to the gallbladder, and between the gallbladder and the gastric antrum, or the proximal duodenum, measuring ≤2 cm, respectively...

BACKGROUND: We applied augmented reality (AR) techniques to flexible choledochoscopy examinations. METHODS: Enhanced computed tomography data of a patient with intrahepatic and extrahepatic biliary duct dilatation were collected to generate a hollow, 3-dimensional (3D) model of the biliary tree by 3D printing. The 3D printed model was placed in an opaque box. An electromagnetic (EM) sensor was internally installed in the choledochoscope instrument channel for tracking its movements through the passages of the 3D printed model, and an AR navigation platform was built using image overlay display...

Surgery remains the mainstay of curative treatment for primary rectal cancer. For mid and low rectal tumors, optimal oncologic surgery requires total mesorectal excision (TME) to ensure the tumor and locoregional lymph nodes are removed. Adequacy of surgery is directly linked to survival outcomes and, in particular, local recurrence. From a technical perspective, the more distal the tumor, the more challenging the surgery and consequently, the risk for oncologically incomplete surgery is higher. TME can be performed by an open, laparoscopic, robotic or transanal approach...

Anteromedial subcostosternal defects, also known as a diaphragmatic hernia of Morgagni (MH), allow potentially life-threatening herniation of the abdominal organs into the thorax. Constituting only a small fraction of all types of congenital diaphragmatic hernias, correct diagnosis of MH is often delayed, owing in large part to nonspecific associated respiratory and gastrointestinal complaints. Once identified, the primary management for both symptomatic and incidentally discovered asymptomatic cases of MH are surgical correction because the herniated contents present increasing risk for strangulation...
