“…The cranial displacement of the diaphragm could have caused a laceration of the adherence of the parietal pleura with the diaphragm. 3 A predisposing factor might be pneumonia, for which our patient was admitted to the hospital during childhood.…”

Laparoscopic pyeloplasty is viable standard minimally invasive alternative to open pyeloplasty for the treatment of ureteropelvic junction obstruction. Intrathoracic bleeding is an extremely rare complication after laparoscopic urological surgery, but it should be suspected and promptly diagnosed in case of worsening hemodynamic status and respiratory parameters during the intra or post-operative course. We report a case of hemothorax complicating an otherwise uneventful LP in an 18-year-old girl.

“…This alignment consists in a rigid transformation (rotation and translation) and is therefore insufficient to initialise the registration correctly. Indeed, due to the gas insufflation, the pre-operative data (liver mesh from the segmented CT scans) geometrically differs form the intra-operative data (reconstructed patch) [44]. To solve this issue, we constraint the biomechanical model (including the vessels and the tumour) with external forces so that it fit better the recovered visible liver surface.…”

This paper presents a method for real-time augmented reality of internal liver structures during minimally invasive hepatic surgery. Vessels and tumors computed from pre-operative CT scans can be overlaid onto the laparoscopic view for surgery guidance. Compared to current methods, our method is able to locate the in-depth positions of the tumors based on partial three-dimensional liver tissue motion using a real-time biomechanical model. This model permits to properly handle the motion of internal structures even in the case of anisotropic or heterogeneous tissues, as it is the case for the liver and many anatomical structures. Experimentations conducted on phantom liver permits to measure the accuracy of the augmentation while real-time augmentation on in vivo human liver during real surgery shows the benefits of such an approach for minimally invasive surgery.

Anatomical changes due to pneumoperitoneum analyzed by MRI: an experimental study in pigs

Abstract: Increasing abdominal pressure up to laparoscopic pressure (14 mmHg) provokes morphological changes in the liver, vascular structures and diaphragm. These changes could be related to functional alterations that different organs experience after the induction of pneumoperitoneum.
