A 90-year-old man was referred to our hospital because of a positive fecal occult blood test. Colonoscopy revealed a lesion with multiple nodules covered with abundant mucus at the hepatic flexure. Computed tomography showed a dilated appendix attached distally to the hepatic flexure. Right hemicolectomy was performed, and the pathological examination revealed a mucinous appendiceal adenocarcinoma infiltrating the hepatic flexure without pseudomyxoma peritonei. The patient is doing well without recurrence 12 months postoperatively. Extraperitoneal drainage of the malignant ascites caused by the fistula may allow for an early diagnosis, while also making it possible to successfully resect the lesion, thus resulting in a favorable outcome.

In hepatic flexure and transverse colon cancer surgeries, mobilizing the right mesocolon and precisely dissecting the gastrocolic trunk of Henle (GTH) are crucial. Previous classifications of GTH tributaries do not guide radical right hemicolectomy due to post-procedural anatomical acquisition. This study analyzed vessel associations, including the middle colic vein (MCV) converging site, right colic artery (RCA) presence, and other GTH tributaries, using ultra-thin CT for reconstruction.

Post-endoscopic mucosal resection (EMR) bleeding, or clinically significant post-EMR bleeding, is influenced by factors such as polyp size, right-sided colonic lesions, laterally spreading tumors, anticoagulant use, and comorbidities like cardiovascular or chronic renal disease. The optimal prophylactic therapy for post-EMR bleeding remains unknown, with no consensus on specific criteria for its application. Moreover, prophylactic measures, including clipping, suturing, and coagulation, have produced mixed results.

Initially hospitalized for a suspected gallstone attack, she later developed gangrenous cholecystitis. She underwent a laparoscopic cholecystectomy, which revealed abscess formation and necrosis extending into the gallbladder duct.

Background: Reduced-port laparoscopic surgery (RPLS) uses the minimum possible number of ports or small-sized ports in laparoscopic surgery. The combination of RPLS and natural orifice specimen extraction (NOSE) minimizes the procedural damage.
Methods: A total of 17 patients diagnosed with right colon cancer were included: 5 patients in the RPLS + NOSE group and 12 patients in the conventional laparoscopic surgery (CL) + mini-laparotomy (ML) group.
