Background: The population are getting older and obesity is growing. Laparoscopic sleeve gastrectomy (LSG) is increasingly used worldwide but is still used with skepticism in the elderly. The purpose of our analysis is to judge the security of LSG in patients older than 60 years compared to patients younger than 60 years.Methods: This retrospective review included data of all patients in Germany who underwent LSG between January 2005 and December 2016.The data were published online in the German Bariatric Surgery Registry. A total of 21,571 operations were gathered and divided into two groups: group I, patients < 60 years old; and group II, patients ≥ 60 years old.Results: The total number of patients and the mean body mass index of group I and group II was 19,786, 51.7 ± 9.5 kg/m2 and 1771, 49.2 ± 8.1 kg/m2, respectively. Regarding comorbidities, group II suffered statistically significantly more comorbidities than group I (p < 0.001). The general postoperative complications were 4.9% in group I and 7.8% in group II (p < 0.001). There was no significant difference in special postoperative complications (p = 0.048) and a slightly higher intraoperative complication rate in group II (2.2% vs. 1.6%, p = 0.048). Thirty-day mortality rate for group I versus II was 0.22% and 0.23% (p = 0.977), respectively.Conclusions: LSG is a low-risk operation and safe surgical method with acceptable, not elevated perioperative morbidity and mortality rates in patients ≥ 60 years of age.

Background. The problems associated with rectal surgery are frequently discussed with no reference being made to the distance of the tumor from the anal verge. This study examined the effect of the location of the tumor on early postoperative results. Patients and methods. This was a multicenter study involving 75 German hospitals and 3756 patients, of whom 1463 had rectal carcinoma. On the basis of the location of the tumor (distance from the anal verge), four groups were distinguished: <4, 4–7.9, 8–11.9, and 12–16 cm. Results. Resection and abdominoperineal resection rates and the incidence of postoperative complications depended on the location of the tumor. Significantly higher resection rates and fewer specific complications, and a significant reduction in overall postoperative morbidity were found with tumor locations more than 8 cm from the anal verge. The highest anastomotic leak rate was observed with anastomoses less than 7 cm from the anal verge. The logistic regression showed that the distance of the tumor from the anal verge is an independent variable for the development of an anastomotic leak. Conclusions. Early results are greatly affected by the location of the rectal carcinoma. This applies to both abdominoperineal resection rates and specific postoperative complications, such as anastomotic leak rate and operation morbidity in general. [ABSTRACT FROM AUTHOR]
