Data to guide surveillance following oncologic extended resection (OER) for gallbladder cancer (GBC) are lacking. Conditional recurrence-free survival (C-RFS) can inform surveillance. We aimed to estimate C-RFS and identify factors affecting conditional RFS after OER for GBC. Patients with ≥ T1b GBC who underwent curative-intent surgery in 2000–2018 at four countries were identified. Risk factors for recurrence and RFS were evaluated at initial resection in all patients and at 12 and 24 months after resection in patients remaining recurrence-free. Of the 1071 patients who underwent OER, 484 met the inclusion criteria; 290 (60%) were recurrence-free at 12 months, and 199 (41%) were recurrence-free at 24 months. Median follow-up was 24.5 months for all patients and 47.21 months in survivors at analysis. Five-year RFS rates were 47% for the overall population, 71% for patients recurrence-free at 12 months, and 87% for the patients without recurrence at 24 months. In the entire cohort, the risk of recurrence peaked at 8 months. T3–T4 disease was independently associated with recurrence in all groups: entire cohort [hazard ratio (HR) 2.16, 95% confidence interval (CI) 1.49–3.13, P

Background Current evidence supports the curative resection of colorectal cancer and synchronous liver and lung metastases in selected patients.1,2 This video shows simultaneous left colectomy, bilobar liver resection, and lung metastasectomy via a transdiaphragmatic approach for stage IV colorectal cancer.3 PATIENT: A 57-year-old man with a stage IV colonic adenocarcinoma was considered for simultaneous resection of primary, liver, and lung metastases without thoracic incision. The tumor mutational status was KRAS, NRAS, and BRAF wild-type, and the patient underwent preoperative chemotherapy. Technique After performing a midline laparotomy, atypical liver resection of segments 8/4a was performed under the guidance of intraoperative ultrasonography and intermittent Pringle maneuver using the two-surgeon's technique. A small capsular lesion in segment 3 also was intraoperatively detected and resected. Lung metastasectomy of the right lower lobe was performed via a transdiaphragmatic approach using an endoscopic stapler. Sigmoid colectomy with transanal circular-stapled anastomosis was performed. Duration of surgery and blood loss were 358 min and 400 ml, respectively. Histopathological examination showed metastatic colonic adenocarcinoma with negative surgical margins and final stage was T3N2aM1b. The patient was discharged on postoperative day 6 without complication. He was alive and free of disease at 90-day follow-up. Conclusions Simultaneous colon, liver, and lung resection via a transdiaphragmatic approach is a feasible and safe surgical strategy in selected patients with peripheral lung metastases and favorable tumor biology.4 This surgical strategy avoids thoracic incision, multiple operations, and may reduce the healthcare costs and the recovery time to early implement postoperative therapy.

Hepatopancreatoduodenectomy is performed to achieve curative resection of malignant biliary tumors.1 However, the morbidity and mortality associated with this challenging surgical procedure remain high, and optimal indications remain unclear.2–4 Biliary papillomatosis (BP) is a precursor lesion of cholangiocarcinoma. This video shows hepatopancreatoduodenecomy for multifocal cholangiocarcinoma in the setting of BP. A 75-year-old man with a medical history of cholecystectomy presented with obstructive jaundice. Magnetic resonance colangiopancreatography and computed tomography scan showed diffuse biliary dilation with mild enhancing nodularities in the whole extrahepatic bile duct. Cholangioscopy with biopsies proved cholangiocarcinoma arising from BP at the prepapillary common bile duct (CBD) and the biliary confluence. The second-order right ducts were free of disease. The patient underwent nasobiliary drainage and was considered for hepatopancreatoduodenecomy. A right subcostal incision was performed. Intraoperative ultrasound showed BP of the intrapancreatic CBD spreading only to the left bile duct. En bloc resection of the left liver, caudate lobe, and CBD was performed together with pylorus-preserving pancreatoduodenectomy. The reconstruction phase was performed on a single-loop by duct-to-mucosa pancreatojejunostomy, two-duct biliojejunostomy with mucosa-to-mucosa alignment, and duodenojejunostomy. Transanastomotic external stents were used for biliary and pancreatic drainage. Histopathologic examination confirmed foci of cholangiocarcinoma arising from BP. Resection margins were negative. Lymph node metastasis, microvascular invasion, perineural invasion, and mucin secretion were absent. The patient was discharged on postoperative day 14 without complications. At the 2-year follow-up assessment, he was alive and free of disease. Cholangiocarcinoma arising from BP is a proper indication for hepatopancreatoduodenectomy. The long-term oncologic benefits might outweigh the possible perioperative complications.5,6
