PURPOSE: To show the benefit of three-dimensional (3D) reconstructions of preoperative imaging for surgical performance. METHODS: A laparoscopic training environment with 15 hidden lymph nodes was designed. Three of them were marked with radiographic contrast agent and were only distinguishable from unmarked nodes via CT imaging. Thirty-six surgeons were divided into two groups. To group 1 the unprocessed CT data were shown. Group 2 was additionally shown a 3D reconstruction of the anatomy...

Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training...

The aim of the present study was to investigate a method of laparoscopic nephron-sparing surgery (LNSS) for renal cell carcinoma (RCC) based on the precise anatomy of the nephron, and to decrease the incidence of hemorrhage and urinary leakage. Between January 2012 and December 2013, 31 patients who presented to the General Hospital of the People's Liberation Army (Beijing, China) were treated for RCC. The mean tumor size was 3.4±0.7 cm in diameter (range, 1.2-6.0 cm). During surgery, the renal artery was blocked, and subsequently, an incision in the renal capsule and renal cortex was performed, at 3-5 mm from the tumor edge...

Laparoscopic radical hysterectomy has been widely performed for patients with early-stage cervical cancer. The operative techniques for nerve-sparing to avoid bladder dysfunction have been established during the past three decades in abdominal radical hysterectomy, but how these techniques can be applied to laparoscopic surgery has not been fully discussed. Prolonged operation time or decreased radicality due to less accessibility via a limited number of trocars may be a disadvantage of the laparoscopic approach, but the magnified visual field in laparoscopy may enable fine manipulation, especially for preserving autonomic nerve tracts...

The cystic artery is the key structure sought to be clipped or ligated during laparoscopic or conventional cholecystectomy. The possible complications like hemorrhage or hepatobiliary injury are always centered on the search, dissection, and clipping or ligation of the cystic artery, many a time because of possibility of variations in its course and relations to the biliary ducts. This descriptive study was carried out to document the normal anatomy and different variations of the cystic artery to contribute to improve surgical safety...

BACKGROUND: Augmented reality (AR) is the fusion of computer-generated and real-time images. AR can be used in surgery as a navigation tool, by creating a patient-specific virtual model through 3D software manipulation of DICOM imaging (e.g., CT scan). The virtual model can be superimposed to real-time images enabling transparency visualization of internal anatomy and accurate localization of tumors. However, the 3D model is rigid and does not take into account inner structures' deformations...

The efficacy of laparoscopic total mesorectum excision (TME) has been confirmed by many clinical trials and guidelines. But two issues on laparoscopic TME are still questioned, including the integrity of specimen membrane of TME and the incidence of postoperative sexual dysfunction. According to my experiences and the primary results of the multicenter clinical trial (LASRE, clinicaltrials.gov identifier: NCT01899547) conducted by me, the integrity of the specimen membrane of laparoscopic TME is not inferior to the open TME...

BACKGROUND: Complete mesocolic excision (CME) with central vascular ligation (CVL) should be employed for the treatment of colon cancer patients because of its superior oncological outcomes. However, this technique is technically challenging in laparoscopic right hemicolectomy because of the anatomical complexity of the transverse mesocolon. METHODS: We focused on the embryology and anatomy of the transverse mesocolon to overcome the difficulty of this surgery. The validity and efficacy of a cranial approach in achieving CME with CVL in laparoscopic right hemicolectomy was elucidated from the embryological point of view...

Background: Roux-en-Y gastric bypass (RYGB) is a standard therapy in bariatric surgery. Sleeve gastrectomy and gastric banding, although with good results in the literature, are showing higher rates of treatment failure to reduce obesity-associated morbidity and body weight. Other problems after bariatric may occur, as band erosion, gastroesophageal reflux disease and might be refractory to medication. Therefore, a laparoscopic conversion to a RYGB can be an effective alternative, as long as specific indications for revision are fulfilled...
