A general exploration of the abdomen is undertaken, with particular attention paid to the duodenal wall for evidence of scarring or deformity. The left hemiliver is then mobilized by dividing the triangular...
Achalasia Treatment: Laparoscopic Heller Myotomy and Dor Fonduplication
Achalasia is a rare esophageal motility disorder that causes progressive dysphagia and regurgitation. The aim of treatment for achalasia is to provide symptom relief by reducing esophageal outflow resistance...
Acute Cholecystitis
Acute cholecystitis is inflammation of the gallbladder that develops over hours, usually because a gallstone obstructs the cystic duct.
Acute Cholecystitis Impact of Blunt Dissection
In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the...
Acute Pancreatitis
Surgical video case: acute pancreatitis can result in retroperitoneal fat necrosis, typically occurring in the peripancreatic region, with extension into the transverse mesocolon, omentum and mesenteric...
Acute Suppurative Cholecystitis / AAST 1
Gallbladder empyema (suppurative cholecystitis 1) is an uncommon complication of cholecystitis and refers to a situation where the gallbladder lumen is filled and distended by purulent material (pus).

Rouviere's Sulcus
Rouviere's sulcus is a 2-5 cm fissure on the liver between the right lobe and caudate process. The benefit of finding the Rouviere's sulcus during laparoscopic cholecystectomy is supported by the fact...
Phrygian Cap Gallbladders
A Phrygian cap is a congenital anomaly of the gallbladder with an incidence of 4%. It can simulate a mass in the liver during hepatobiliary imaging and is sometimes mistaken for pathology.
Laparoscopic Appendectomy
Surgical video case: the method used for closure appendix base during laparoscopic appendectomy is important in terms of the simplicity of application, biocompatibility, price and other characteristics...
Acute Suppurative Gangrenous Appendicitis
Increasing intraluminal pressures eventually exceed capillary perfusion pressure, which is associated with obstructed lymphatic and venous drainage and allows bacterial and inflammatory fluid invasion...
Lap Appendectomy in Acute Appendicitis
The role of laparoscopic appendectomy is still not well defined in the literature. Laparoscopic appendectomy is feasible in developing countries with similar postoperative outcome and less requirement...
Biliary Stent Removal
Laparoscopic common bile duct exploration (LCBDE) has been found to be a safe, efficient and cost-effective treatment for choledocholithiasis. Following LCBDE, the clearance may be ascertained by a cholangiogram...
Hourglass Gallbladder
Gallbladder anatomy is highly variable, and surgeons must be prepared to identify anomalies of form, number, and position. Variants include gallbladder agenesis, diverticulum, duplication, bilobed, multiseptate,...
Lap Appendectomy
Similar to open appendectomy, most of the methods described for laparoscopic appendectomy. Dissection and hemostasis of mesoappendix using (brand hidden) and appendiceal stump closure by (brand hidden)...
Gallbladder Mucocele
The term gallbladder mucocele refers to an overdistended gallbladder filled with mucoid or clear and watery content. Usually noninflammatory, it results from outlet obstruction of the gallbladder and...
Acute Suppurative Cholecystitis / AAST 1
Gallbladder empyema (suppurative cholecystitis 1) is an uncommon complication of cholecystitis and refers to a situation where the gallbladder lumen is filled and distended by purulent material (pus).
TAR Hernioraphy
Video case: complex ventral hernia repair is a frequent and challenging topic. Reconstructive techniques are numerous but most of them are unable to achieve the goals of hernioplasty. Posterior component...
Cholecystocolic Fistula
The cholecystocolonic fistula is an atypical variant of biliary disease. When presenting with symptomatic disease, surgical treatment with cholecystectomy, fistula takedown and possible colonic resection...
Jejunojejunal Intussusception
Intussusception is defined as the telescoping of one segment of the gastrointestinal tract (intussusceptum) into an intestinal segment distal to it (intussuscipiens). Intestinal invagination or intussusception...
Loop Gastrojejunostomy
Laparoscopic gastrojejunostomy (LGJ) has been proposed as the technique preferred over open gastrojejunostomy for relieving gastric outlet obstruction (GOO) due to malignant and benign disease. After...
Critical View of Safety During Acute Cholecystitis
The cause of most major bile duct injuries is misidentification of ductal structures. In the “classical” injury, the common bile duct is thought to be the cystic duct and is divided. Division...
