“…Of these studies, 12 were excluded for various reasons: 3 used other variable definitions of obesity [2,12,13]; 5 compared outcomes in tertiles or quartiles of BMI [14][15][16][17][18]; 1 evaluated the clinical outcomes of patients with morbidly obese [19]; and 2 were review [1,20]. In total, eight observational studies published between 2002 and 2009 matched the inclusion criteria and were therefore included [4-9, 21, 22].…”

“…There are several studies documenting the increased surgical complication risk in major abdominal and cardiac surgery in obese patients [3][4][5]. However, the role of obesity on cervical endocrine procedures has been much less investigated [6][7][8].…”

“…Only the age value showed compatibility with normal distribution within the groups, data of other variables were detected as out of normal distribution within the groups. Data concerning the age variable compatible with normal distribution were analyzed by one-way ANOVA and Turkey's HSD Post-hoc procedures, especially in major abdominal surgeries such as colectomy or pancreaticoduodenectomy [3][4][5]. There are some recent reports associated with the risk of morbidity and mortality also in parathyroid surgery [6][7][8].…”

Aim-Background: Obesity prevalence has increased all over the world and has become an epidemic disease. Studies in the literature show that obese patients who have undergone various surgical operations have an increased risk of morbidity and mortality. There are several studies on morbidity and mortality in parathyroid surgery. However, there is insufficient information concerning the thyroidectomy outcomes of obese patients. The aim of this study is to evaluate the effect of obesity in the postoperative stage and minimize the disadvantages that can be seen in obese patients undergoing total thyroidectomy. Materials and Methods: Ninety-nine patients who underwent total thyroidectomy between April and September 2012 were included in this study. Patients who were under/normal weight were grouped as Group 1, overweight as Group 2, obese as Group 3. The analyzed parameters include incision length, operation duration, specimen weight, postoperative pain, postoperative early complications, amount of postoperative drainage, and duration of postoperative hospital stay. Results:The average age of the patients was 50.4 years. Seventy-one patients were women and 28 were men. No differences were noticed among the groups in terms of age, gender, sternomental length, operation duration, pain score, amount of postoperative drainage, postoperative hospital stay, vocal cord paralysis, hypocalcaemia, bleeding that required re-operation, specimen weight, and incision length. No relation between operation duration and specimen weight was observed. The relation between specimen weight and incision length was evaluated and a meaningful but weak correlation was observed. No wound infection was seen.Conclusion: Total thyroidectomy can be performed safely even in obese patients.

“…Obstacles to performing laparoscopic surgery in obese patients include difficulties in obtaining an adequate operative field and difficulties in the intraabdominal maneuvering of instruments in a restricted working area. 2,16 These difficulties may also affect oncologic outcomes following colorectal cancer. However, this study showed no adverse effect of obesity on survival following laparoscopic colorectal cancer surgery.…”

“…In terms of short-term outcomes, several studies have shown that obese patients have unfavorable surgical outcomes, such as longer operative times, increased conversion rates, increased postoperative complication rates, and prolonged hospital stays. [1][2][3] These unfavorable short-term outcomes may affect long-term outcomes for obese patients with colorectal cancer. However, some studies in Western patients showed that long-term outcomes for obese patients were not different from those for non-obese patients.…”

Purpose:The adverse effects of obesity on short-term surgical outcomes after laparoscopic colorectal surgery have been reported. However, the influence of obesity on long-term oncological outcomes after laparoscopic surgery in Asian patients has not been well understood. The aim of this study was to evaluate the effect of obesity on long-term oncologic outcomes in patients who underwent laparoscopic surgery for colorectal cancer. Results:Of the 424 patients, 325 (76.7%) were classified as non-obese and 99 (23.3%) as obese. The clinicopathologic characteristics of the obese and non-obese groups were similar, except that there were more underlying comorbidities, a lower frequency of smoking, and fewer tumors in rectum in the obese group. Results of the multivariate analysis showed that older age, elevated serum carcinoembryonic antigen, high-grade histology, advanced tumor stage, and perineural invasion were associated with poorer disease-free survival and overall survival. Obesity was not significantly associated with disease-free survival (hazard ratio [HR] Conclusion:Laparoscopic surgery for colorectal cancer seems to be safe and feasible for obese patients in terms of long-term oncologic outcomes.
