Comparative Study Clinical Trial
Incisional hernia prophylaxis in morbidly obese patients undergoing biliopancreatic diversion.
The development of incisional hernia after open bariatric surgery is a major cause of morbidity and hospital readmission. The use of prosthetic material in clean-contaminated procedures remains controversial and correlated to high rate of local complications. A prospective observational clinical study on two different surgical techniques used to close the abdominal wall has been performed to better assess the safety (primary end point) and the efficacy (secondary end point) of polypropylene mesh placement to prevent incisional hernia in morbidly obese patients undergoing biliopancreatic diversion (BPD). ⋯ The mesh placement in clean-contaminated bariatric surgery seems to be safe (primary end point) and effective (secondary end point) at 1-year follow-up.

Ghrelin and leptin recently emerged as the most influential neuroendocrine factors in the pathophysiology of obesity. The said peptides act in reciprocity and are responsible for regulation of appetite and energy metabolism. Intragastric balloons acquired worldwide popularity for obesity treatment. However, the roles of ghrelin and leptin in intragastric balloon treatment were still not systematically studied. ⋯ The importance of ghrelin and leptin in treatment-induced changes was reaffirmed. Ghrelin hyper-response in non-morbidly obese subjects characterized greater short-term treatment efficiency and landmarked an inclination to weight regain. The results suggest a potential pattern of individualization between obese patients according to body mass index towards intragastric balloon or bariatric surgery. Further studies are needed in order to get better insights in the pathophysiologic mechanisms of obesity.

Laparoscopic adjustable gastric banding (LAGB) is a proven method for weight reduction. Less is known about pregnancies in patients after LAGB. ⋯ LAGB is tolerable in pregnancy with rare intrapartum band slips. Weight gain is less in those with higher pre-pregnancy BMI and those who had their bands filled or not adjusted. Babies born to these mothers are as healthy as the general population.

Considerable controversy exists about the perioperative management of patients at high risk for obstructive sleep apnea (OSA) in free-standing clinics. Eighty-eight percent of an American Society of Anesthesiologists expert panel felt that upper abdominal laparoscopic surgery could not be performed safely on an outpatient basis. We sought to review the incidence of major adverse events after outpatient laparoscopic adjustable gastric banding (LAGB) in a high risk population for OSA at a free-standing facility. ⋯ There were no deaths and no cases of respiratory failure or re-intubation. The 30-day mortality was zero and the 30-day anesthesia related morbidity was less than 0.5%. For patients at high risk for OSA after LAGB, the significance of transient oxygen desaturation and the need to develop monitoring and admission standards remain to be determined.
