Background: Anastomotic stricture remains the most common complication after laparoscopic gastric bypass with a circular-stapled gastrojejunostomy. The present study examined the effect of the use of bioabsorbable circular staple line reinforcement on the incidence of gastrojejunostomy anastomotic strictures as a complication of laparoscopic Roux-en-Y gastric bypass.
Methods: A retrospective review was performed of 851 consecutive patients who underwent laparoscopic Roux-en-Y gastric bypass with circular-stapled gastrojejunostomy. Gore SeamGuard bioabsorbable circular staple line reinforcement was used in 596 consecutive patients subsequent to 255 consecutive patients without anastomotic reinforcement. The incidence of anastomotic stricture was compared after mean follow-up periods of 19 and 22 months for the two groups.
Results: Anastomotic stricture requiring intervention was identified in 28 patients (2.94%). Only four patients (.67%) in the SeamGuard group developed anastomotic stricture compared with 24 patients (9.41%) in the no SeamGuard group. The use of staple line reinforcement is consistent with a 94% risk reduction in stricture formation.
Conclusion: The results have shown that the use of bioabsorbable circular staple line reinforcement on gastrojejunal anastomoses in laparoscopic Roux-en-Y gastric bypass significantly reduces the incidence of anastomotic stricture. The standard use of the bioabsorbable reinforcement on circular staple line anastomoses could be a part of the solution to the most common complication of laparoscopic gastric bypass.

Laparoscopic Reversal of Roux-en-Y Gastric Bypass with Hand-Sewn Gastro-Gastrostomy and Resection of the Alimentary Limb.

Introduction: Roux-en-Y gastric bypass (RYGB) reversal might be necessary to alleviate refractory surgical or nutritional complications, such as postprandial hypoglycemia, malnutrition, marginal ulceration, malabsorption, chronic diarrhea, nausea and vomiting, gastro-esophageal reflux disease, chronic pain, or excessive weight loss. The surgical technique of RYGB reversal is not standardized; potential strategies include the following: (1) gastro-gastrostomy: hand-sewn technique, linear stapler, circular stapler; (2) handling of the Roux limb: reconnection or resection (if remaining intestinal length ≥ 4 m).
Case Presentation: We demonstrate the surgical technique of a laparoscopic reversal of RYGB with hand-sewn gastro-gastrostomy and resection of the alimentary limb with the aim of improving the patient's quality of life.

To evaluate the clinical efficacy of modified endoscopic mucosal resection (EMR) in the management of early gastrointestinal lesions. Upon endoscopic identification of the lesion, normal saline is injected into the submucosa to establish a fluid cushion, which elevates the lesion's mucosa. Methylene blue may also be applied to improve visualization of the relationship between the submucosa and muscular layer.

Background: Laparoscopic total gastrectomy (LTG) is still limited because intracorporeal oesophagojejunostomy is technically demanding and difficult in laparoscopic gastrectomy. Circular-stapled anastomosis is considered the "gold standard" method for oesophagojejunostomy in open total gastrectomy. A purse-string suture instrument is used to create a purse-string suture along the distal oesophagus as a standard technique for classic circular-stapled oesophagojejunostomy in the open total gastrectomy.

Background: Candy cane (CC) syndrome is a complication that occurs following Roux-en-Y bypass (RYGB), implicated as a long, small-bowel blind limb at gastrojejunostomy possibly caused using circular staplers.
Objectives: We aimed to report our experience with CC resection and improving outcomes following RYGB.

Gastric cancer (GC) treatment is increasingly undergoing laparoscopic total gastrectomy (LTG) procedures. However, we conducted this research to evaluate postoperative outcomes, particularly surgical complications associated with intracorporeal and extracorporeal esophagojejunostomies using linear or circular stapling techniques following LTG for GC treatment. We aimed to compare short-term postoperative outcomes, such as surgical complications and anastomotic outcomes, between the two groups.
