Laparoscopic surgery offers new challenges for the general surgeon and pediatric surgeon, hence the need for an adequate training before intervening patients directly. There are different models designed in vitro as well as in vivo. Objectives: To evaluate the utility of the rabbit as an experimental model for pediatric laparoscopic surgery training Methods: Nineteen rabbits of the species Oryctolagus cuniculus were included in the study, 16 females and 3 males. Sixty five surgical procedures of Level I, Level II and Level III were distributed as follows: 16 diagnostic laparoscopies, 12 surgical sterilizations, 12 oophorectomy, 8 appendectomies, 10 gastrostomies, 2 gastric sutures, 2 gastroenteroanastomosis and 3 intestinal anastomosis. The measured time to perform the diagnostic laparoscopy included the placement and trocars fixation as well as the rabbit systematic revision of all abdominal cavity quadrants, while the time for the remaining procedures was timed without considering the placement of the trocar. The average times for each surgical procedure were: diagnostic laparoscopy: 29.17 min., surgical sterilization: 4.33 min., oophorectomy: 4.47 min., appendectomy: 22.17 min., gastrostomy: 32.10 min., gastric suture: 15.05 min., gastroenteroanastomosis: 49.05 min., and intestinal anastomosis: 106.67 min. The cost of surgical material, anesthetics and rabbits, was estimated in 160 BsF per animal involved, for a total investment of 3.040 BsF. We conclude that the rabbit is an adequate model for pediatric laparoscopic surgery training because it is possible to simulate a large number of surgical procedures, besides its low costs and availability.

Type 2 diabetes mellitus (T2DM) is traditionally viewed as a chronic and progressive disease in which delay of end-organ complications is the major treatment goal. Metabolic surgery offers a new horizon: complete disease remission. Scientific evidence demonstrates that certain operations, in special gastric band, duodenal-jejunal exclusion and gastric bypass improve glucose homeostasis through varied mechanisms. The trials that have studied T2DM patients who underwent metabolic surgery have shown favourable outcomes in improving beta-cell function, insulin sensitivity, insulin secresion and reducing insulin resistance modifying some hormones involved in satiety and glucose homeostasis such as leptin, ghrelin and adiponectin, glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptid. These procedures have also been associated with remission of T2DM and better metabolic control in patients with the disease, making them a good alternative in the treatment of T2DM in selected patients.

The short bowel syndrome appears for the reduction of intestinal absorptive surface due to functional or anatomical loss of part of the small bowel. We present the case of a 35-year-old woman with severe short bowel syndrome secondary to acute intestinal ischemia in adults, who presented at 5 years of evolution episodes of dizziness with gait instability and loss of strength in hands. The diagnosis was D-lactic acidosis. D-lactic acidosis is a rare complication, but important for their symptoms, of this syndrome. It is due to a change in intestinal flora secondary to an overgrowth of lactic acid bacteria that produce D-lactate. D-lactic acidosis should be looked for in cases of metabolic acidosis in which the identity of acidosis is not apparent, neurological manifestations without focality and the patient has short bowel syndrome or patients who have had jejuno ileal bypass surgery. Appropriate treatment usually results in resolution of neurologic symptoms and prevents or reduces further recurrences. [ABSTRACT FROM AUTHOR]
