The primary purpose of screening colonoscopy is the detection and subsequent removal of precancerous polyps. However, effective recognition of appendiceal lesions with a standard endoscope is often challenging and is limited to the base of the cecum and appendiceal orifice. The majority of appendiceal polyps are found incidentally following an appendectomy, though rarely they may be discovered during a colonoscopy. Despite being visualized by colonoscopy, most of these polyps are generally referred for surgical resection. The risk of developing carcinoma in patients with appendiceal polyps is likely similar to that of other colonic polyps, so it is essential for the endoscopist to examine and visualize the appendiceal orifice thoroughly. Various techniques are available to the endoscopist that can increase the accuracy of colonoscopic evaluation. These include luminal inflation and deflation, looking behind and pressing haustral folds, and repetitive passage of the scope over poorly visualized areas.

Gliomas are infiltrating tumors in the healthy brain parenchyma with no clear boundaries and can be located near or within "functional" brain zones driving as an example, motor skills, sensitivity, cognition or vision. Two conflicting objectives must be achieved during cerebral glioma surgery: (1) to obtain a tumor excision as complete as possible, the oncological prognosis being improved by surgery; and (2) to limit the risk of definitive neurological deficit by respecting the brain areas infiltrated by the tumor remaining functional. The objective of our work is to develop an intraoperative biomecanical analysis and a micro vascularization imaging method and validate the interest of these techniques for the diagnosis of tumor neo-angiogenesis and ultimately to target the surgical procedure during surgery.

Laparoscopic adjustable gastric banding was previously a commonly performed bariatric procedure. However, in recent years, the procedure has become less commonly performed. Long-term complications nonetheless persist and continue to be seen in clinical practice. We present a case of an esophago-pleural fistula complicating a longstanding laparoscopic adjustable gastric band in a woman presenting with persistent empyema. Palliative esophageal stenting was successfully performed, and the patient was discharged home on hospice care per her family’s wishes.
