Laparoscopic cholecystectomy for gangrenous cholecystitis in around nineties: Two case reports

Figure 1 An abdominal contrast-enhanced computed tomography (Case 1). A: Small calculus in the gallbladder neck (arrow); B: Significant swelling of the gallbladder and asymmetrical wall thickening. The gallbladder wall indicated parts with either poor or no contrast enhancement (arrow), with a partial failure of continuity of the mucosa.

Figure 2 An abdominal contrast-enhanced computed tomography (Case 2). A: Significant swelling of the gallbladder. Ascites around the liver; B: There was asymmetrical gallbladder wall thickening and the continuity of part of the wall was ambiguous (arrow).

Figure 3 Surgical observations and surgical techniques (Case 1). A: Gallbladder necroses and a part thereof is perforated (arrow), with leaking of bile; B: Gallbladder neck had substantial inflammation; C: Upon exfoliation from the base to the neck of the gallbladder, we treated the neck using an autosuture; D: After subtotal resection of the gallbladder, the arrow is the amputation stump of the gallbladder neck; E: Resected specimen.

Figure 4 Surgical observations and surgical techniques (Case 2). A: The gallbladder had significant swelling and diffuse necrosis; B: The arrow is a cystic duct; C: For the cystic duct and gallbladder neck, we performed ligature/treatment using a looped absorbable monofilament suture; D: After subtotal resection of the gallbladder, the arrow is the amputation stump of the gallbladder neck; E: Resected specimen.
