Laparoscopic ureteral anastomosis in a patient with hydronephrosis due to a severe endometriosis
Ureteral endometriosis is unfrequent and it is defined by the presence of endometrial glands in the ureteric or pre-ureteric tissue. The prevalence reported is less than 1% and usually confined to the lower one-third of the left ureter. This pathology generates a ureteral stenosis, with an extrinsic compression of the ureteral wall by the inflammatory response and fibrosis, or an intrinsic stenosis with the invasion of the uro-epithelium and submucosal layer of the ureteral wall. We present a short video describing the technique of the laparoscopic segmental ureteral resection followed by the re-anastomosis.

Emergency endoscopic removal of intragastric balloon for hematemesis and melena
The BioEnterics® Intragastric Balloon (BIB®) System has been developed as a temporary aid to achieve weight loss in obese people that are 40% or more above their optimal weight, in patients who have had unsatisfactory results in their treatment of morbid obesity despite being cared for by a multidisciplinary team, and in superobese patients for whom surgery is often associated with high risks. The BIB® reduces the volume of the stomach and leads to a premature feeling of satiety. The placement and removal of the BIB® is an interventional endoscopic procedure and the balloon is designed to float freely inside the stomach; its size can be changed during the placement.
The technique has absolute contraindications such as voluminous hiatus hernia, abnormalities of the pharynx and esophagus, esophageal varicose veins, use of anti-inflammatory or anti-coagulant drugs, pregnancy and psychiatric disorders. Relative contraindications are esophagitis, ulceration and acute lesions of the gastric mucous membrane. The complications of the BIB® are related to the endoscopic method itself, to sedation and perforation, to its prolonged contact with the mucous membrane and its migration, which may result in esophageal or intestinal obstruction (1). The patients must be clinically supervised during the BIB® placement. Complications and symptoms, such as esophageal injury and vomiting due to BIB® slippage must be described to the patient, along with the possibility that the BIB® may require early endoscopic removal. Since the BIB® works as an artificial bezoar, the patients usually show a maximal reduction in ingestion around the fourth week, and return to normal after 12 weeks.

Laparoscopic left pancreatectomy with spleen preservation for a suspicion of IPMN
Laparoscopic distal pancreatectomy is suitable for benign and premalignant neoplasms located in the body and tail of the pancreas. Spleen preservation following distal pancreatectomy is known to be safe. There are two distinct approaches to preserve the spleen during the dissection of the distal pancreas. The classic design is to identify, isolate, and preserve the splenic artery and vein. Alternatively, the splenic artery and vein are ligated with the pancreas, and perfusion of the spleen is assured by the short gastric vessels. Both are accepted as appropriate techniques to address a mass in the tail of the pancreas. This video demonstrates a left pancreatic resection with spleen preservation and ligation of the splenic artery and vein.
