We present the correlation between excised specimen size in laparoscopic sleeve gastrectomy and patient demographics, comorbidities, and postoperative weight loss. ⋯ There was no correlation between excised stomach size in laparoscopic sleeve gastrectomy and postoperative weight loss (percent of excess body weight lost) or change in BMI. Male gender, diabetes, and increasing patients' age correlated with larger excised stomach size. Initial BMI and having histological gastritis did not correlate with excised stomach size.

Comparative Study
Postoperative Care and Functional Recovery After Laparoscopic Sleeve Gastrectomy vs. Laparoscopic Roux-en-Y Gastric Bypass Among Patients Under ERAS Protocol.
The most commonly performed bariatric procedures are laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). There are major differences between LSG and LRYGB during postoperative period. Optimization of the postoperative care may be achieved by using enhanced recovery after surgery (ERAS) protocol, which allows earlier functional recovery. ⋯ In our opinion, postoperative treatment after LSG requires more supervision and longer time until functional recovery is achieved.

Pharmacokinetic data suggest that the risk of metformin-associated lactic acidosis (MALA) may be increased after Roux-en-Y gastric bypass (RYGB) surgery. The aim of this study was to examine the impact of metformin on plasma lactate levels before and after RYGB surgery. ⋯ Mild hyperlactatemia (lactate > 2 mmol/l) is common in morbidly obese patients with T2DM. It is probably related to increase lactate production by adipocytes. Lactate levels decreased after RYGB-induced weight loss, irrespective of the use of metformin. We therefore conclude that there is no need for routinely lowering of the metformin dose after uncomplicated RYGB surgery, as long as normal renal function is preserved.
