Laparoscopic sleeve gastrectomy in patients over 60 years: impact of age on weight loss and co-morbidity improvement.

BACKGROUND: Advanced age has traditionally been considered a relative contraindication to bariatric surgery due to increased perioperative risk and less weight loss. However, it is now being reconsidered in older patients after encouraging results in recent series and the increasing life expectancy. We compared operative and postoperative outcomes of laparoscopic sleeve gastrectomy in patients over 60 years with outcomes in younger patients. We also, analyzed the effect of bariatric surgery on improvement and resolution of co-morbidities in the older group. METHODS: From November 2008 to November 2013, 130 patients underwent laparoscopic sleeve gastrectomy. Of these, 28 patients (21.5%) were 60 years or older. Outcomes in terms of perioperative complications, short-term and medium-term weight loss, remission or improvement of co-morbidities and medication requirements were extracted from our prospective database. RESULTS: Short-term mortality was 0% and 30-day complication rate was similar in both groups (17.9% versus 17.6% according to Clavien-Dindo classification). At 12 months postsurgery, older patients had lost 49% percent of excess weight compared to 60% in the younger group (P = 0.012). At 2 years, the results were 45% versus 60%, respectively, with P = 0.015. At least 1 major co-morbidity improved in 65.2% of older patients. Before surgery, the older group took an average of 4.3 medications compared to 2.7 at 1 year after surgery (P<0.001). CONCLUSION: Laparoscopic sleeve gastrectomy is a safe and effective treatment for morbid obesity in people over 60 years, although younger patients show greater weight loss. Daily medication requirements and co-morbidities decrease significantly in older patients after this procedure.

Laparoscopic approach to retrorectal tumors: review of the literature and report of 4 cases.

BACKGROUND: Retrorectal or presacral tumors are extremely rare and their histologic origin varies greatly. Surgical excision is indicated to prevent complications or to rule out malignancy. A laparoscopic approach has been infrequently reported to date. The aim of this article is to report our experience in 4 cases, and to review the current world experience on laparoscopic approach to retrorectal tumors. METHODS: Between 1998 and 2009, we operated 4 cases in which a presacral tumor was diagnosed. A pure laparoscopic procedure was performed in 3 cases and a combined laparoscopic/transacral approach in a fourth. In addition, a systematic literature review and relevant reports on laparoscopic approach of these tumors were analyzed. RESULTS: All patients underwent laparoscopic dissection of the tumor with extraction through a Phannestiel incision except in 1 case that was performed transsacrally. Simultaneously, the literature review showed 11 articles with a total number of 18 patients approached by laparoscopy. CONCLUSIONS: The laparoscopic approach of retrorectal tumors is feasible. The advantages are an enhanced access and visualization of the pelvic structures and a more controlled preservation of nerve and vascular integrity. It seems to be a safe procedure and can be combined with a posterior approach if needed.
