Transumbilical single-access laparoscopic sleeve gastrectomy plus 1.8-mm trocarless grasping forcepsLaparoscopic sleeve gastrectomy is gaining popularity throughout the world. Generally, it is performed using 5–7 abdominal trocars but can also be performed through a single-access laparoscopy (SAL) at the umbilicus. This incision is in line with the axis of the stomach, providing access to the stomach without many difficulties. Moreover, the access site can be enlarged to remove the resected stomach from the abdomen with relatively better cosmesis, since the scar is the original umbilical scar.
Laparoscopic management of gastric leak secondary to distal staple line disunion after sleeve gastrectomyLaparoscopic sleeve gastrectomy (SG) has become very popular  due to its apparent technical ease, positive results (in terms of weight loss and improvement of co-morbidities , and low postoperative complication rates. Major complications are gastric leak (GL) and hemorrhage along the gastric staple line. GL is found in less than 3% of cases  and mostly occurs between postoperative day 5 and 8 .
Laparoscopic hand sewn regastrojejunostomy for complicated Roux-en-Y gastric bypassLaparoscopic Roux-en-Y gastric bypass (LRYGB) is a popular bariatric procedure associated to potential risk of late complications like anastomotic marginal ulceration, stricture, fistula formation, weight gain, and nutritional deficiencies [1–6].
Malrotation—an unexpected finding at laparoscopic Roux-en-Y gastric bypass: a video case reportLaparoscopic Roux-en-Y gastric bypass (LRYGB) is 1 of the most common procedures performed for severe obesity. Incidental anatomic abnormalities found at surgery are uncommon and can require an alternative operative approach. We present a video case report of a patient incidentally found to have midgut congenital malrotation at LRYGB.
Laparoscopic reduction of small bowel intussusception in a 33-week pregnant gastric bypass patient: surgical technique and review of literatureIntussusception is a rare etiology of bowel obstruction in adults and accounts for 1–3% of those cases. It is associated with an underlying mass such as a tumor or polyp in >80% of patients [1–4]. In gastric bypass patients, intussusception is an uncommon complication [5,6]. The common channel distal to the jejunojejunostomy is the usual site of intussusceptions. The direction of intussusception can be either antegrade or retrograde, but most reported cases are retrograde in nature. The probable etiology can include the presence of an ectopic pacemaker causing retrograde peristalsis.
Hand-sewn laparoscopic duodenal switchThe duodenal switch (DS) is an alternative operation to the Scopinaro biliopancreatic diversion. Hess and Hess  performed the first case in March 1988 in 1 woman with a body mass index (BMI) of 60 kg/m2 and a BMI of 29 kg/m2 17 years later. Marceau et al.  published the first report on the procedure, followed by Baltasar et al. [3,4], who published additional series. Ren et al.  performed the first laparoscopic DS (LDS) in July 1999 and Baltasar et al. [6,7] published the second world experience.
