Laparoscopic Appendectomy
The stapling devices make laparoscopic appendectomy simpler and faster. Especially in situations where the base of the appendix is inflamed, using a stapler is safer than endoloop Or clips. The multi-fire...
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...
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...

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...

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).
