The increasing use of laparoscopy has resulted in added complications specific to the laparoscopic approach, such as trocar site hernia (TSH), which is an uncommon but well-recognized problem for both regular laparoscopic and robotic-assisted laparoscopic procedures. We describe an extremely rare case of TSH at an 8-mm port site occurring a relatively short time after surgery in a 53-year-old p...

O II Congresso Brasileiro de Investigação e Reabilitação Neurológica (COBREN) teve como objetivo discutir novas atualizações perspectivas cunho investigativo científico, foram apresentados trabalhos inovadores. Destinado a reunir todos os pesquisadores, com o trocar informações sobre vários aspectos das funções disfunções neurológicas, principalmente quanto às formas avaliação, terapêuticas tec...

BACKGROUND AND PURPOSE Optimal placement allows intuitive laparoscope positioning between two working trocars (0 degrees angle). However, this configuration may require the assistant to operate in an awkward position. We evaluated the effect of alteration of laparoscope position on surgeon performance and correlated this with surgical experience. SUBJECTS AND METHODS Participants were stratif...

TECHNIQUE An open Hasson entry in the left hypochondrium, at least 5cm lateral to the defect edge, and two 5mm trocars in the subxiphoid area and left iliac fossa serve to take down hernia sac adhesions and completely expose the abdominal wall defect. Another 10mm trocar is inserted in the midline just cephalad (or caudal) to the defect to receive the camera, together with a 5mm access in the r...

Laparoscopy is used as a diagnostic and therapeutic tool in gynecologic oncology, including the follow up of patients with known ovarian carcinoma. It offers an excellent magnified view of pelvis and anterior abdominal contents. In addition, the operator can easily obtain specimens from suspected sites of involvement and can make laparoscopy guided washings. We present a case of tumor implant o...

We report perforations of a pregnant uterus during laparoscopy for suspected internal herniation after gastric bypass at 24 weeks of gestation. Abdominal access and gas insufflation were achieved by the use of a 12 mm optic trocar. An additional 5 mm trocar was positioned. The perforations were handled by suturing following laparotomy and mobilisation of the high located uterus. The uterine fun...

OBJECTIVE Orthotopic models are important in cancer research. Here we developed orthotopic xenograft mouse model of metastatic lung cancer and glioblastoma with a specially designed system. METHODS Tiny fragments of surgical tumors were implanted into the mice brain with a trocar system. Immunohistochemistry was performed to detect brain tumor stem cells among glioblastoma tissues, including ...
