RESUMO
BACKGROUND: 'Textbook Outcome' (TO) represents an effort to define a standardized, composite quality benchmark based on intraoperative and postoperative endpoints. This study aimed to assess the applicability of TO as an outcome measure following liver resection for hepatic neoplasms from a low- to middle-income economy and determine its impact on long-term survival. Based on identified perioperative predictors, we developed and validated a nomogram-based scoring and risk stratification system. METHODS: We retrospectively analyzed patients undergoing curative resections for hepatic neoplasms between 2012 and 2023. Rates of TO were assessed over time and factors associated with achieving a TO were evaluated. Using stepwise regression, a prediction nomogram for achieving TO was established based on perioperative risk factors. RESULTS: Of the 1018 consecutive patients who underwent liver resections, a TO was achieved in 64.9% (661/1018). The factor most responsible for not achieving TO was significant post-hepatectomy liver failure (22%). Realization of TO was independently associated with improved overall and disease-free survival. On logistic regression, American Society of Anesthesiologists score of 2 (p = 0.0002), perihilar cholangiocarcinoma (p = 0.011), major hepatectomy (p = 0.0006), blood loss >1500 mL (p = 0.007), and presence of lymphovascular emboli on pathology (p = 0.026) were associated with the non-realization of TO. These independent risk factors were integrated into a nomogram prediction model with the predictive efficiency for TO (area under the curve 75.21%, 95% confidence interval 70.69-79.72%). CONCLUSION: TO is a realizable outcome measure and should be adopted. We recommend the use of the nomogram proposed as a convenient tool for patient selection and prognosticating outcomes following hepatectomy.
RESUMO
BACKGROUND: Open radical cholecystectomy is the current "gold standard" for the management of gallbladder cancer. In well-selected patients, robotic radical cholecystectomy (RRC) can be a suitable alternative offering immediate postoperative benefits, such as less blood loss, shorter hospital stay, and fewer complications, while being oncologically equivalent. However, it requires a longer learning curve.1 METHODS: This video demonstrates the technical equivalence of the robotic approach when performing portal lymphadenectomy (station 8, 12, and 13) with emphasis on retraction techniques to emulate the open approach. In the case presented, a 40-year-old female patient had an intraluminal gallbladder mass with periportal nodes as revealed by computed tomography. Patient underwent a RRC with portal lymphadenectomy, performed on the DaVinci Xi robotic system. The surgery can be divided into five major steps: (1) Station 16b1 node sampling in the inter-aortocaval region; (2) Right portal lymphadenectomy (station 13, 12b, 12p); (3) Left portal lymphadenectomy (station 8a, 8p, 12a, 12p); (4) Anterior portal lymphadenectomy (station 12a, 12b); and (5) Cholecystectomy with liver wedge resection. The technical nuances of each of these steps is compared with its counterpart in the open approach to demonstrate equivalence. The key element in achieving a thorough oncological clearance is to replicate the retraction techniques of the open approach on the robotic platform by using vessel tapes for portal lymphadenectomy. CONCLUSIONS: There remains little doubt regarding the feasibility and early postoperative benefits of RRC.2 This video demonstrates the equivalence of a standardized technique of robotic portal lymphadenectomy and liver wedge resection to the open approach. However, prospective studies are needed to further evaluate the long-term benefits of the procedure.
RESUMO
BACKGROUND: Intraoperative unresectability, postoperative deaths and early recurrences remain devastating futile events in the surgical management of Intrahepatic cholangiocarcinomas (iCCA) and Perihilar cholangiocarcinomas (pCCA). The present study aims to determine the preoperative predictors of futile surgery in cholangiocarcinomas. METHODS: Consecutive hepatectomies for iCCA and pCCA, between September 2010 and June 2022 were included. Futility of surgery was defined as either intraoperative unresectability, postoperative 30-day mortality or recurrence within six months of surgery. Multivariable logistic regression was used to identify predictors of futility. RESULTS: One hundred and fifty patients of iCCA and pCCA underwent surgery during the time period. Thirty-seven (38.1 %) out of 97 patients of iCCA and 25(47.16 %) out of 53 patients of pCCA underwent futile resection. The predictive factors of futile surgery for iCCA were tumour number (≥2) (OR, 9.705; 95%CI, 2.378-39.614; p = 0.002), serum aspartate transaminase (OR, 8.31; 95%CI, 2.796-24.703; p < 0.001) and serum CA-19.9 (>37 U/ml) (OR, 2.95; 95%CI, 1.051-8.283; p = 0.04). The predictive factors of futility for pCCA were lymph node involvement (OR, 7.636; 95%CI, 1.824-31.979; p = 0.005) and serum alkaline phosphatase (>562.5 U/L) (OR, 11.211; 95%CI, 1.752-71.750; p = 0.011). CONCLUSION: Futile surgery was observed in over one third of our patients. Five strong preoperative predictors of futility were identified. Careful analysis of these factors may reduce futile surgical explorations.

OBJECTIVE: To determine the clinical utility of serum CA 19-9 surveillance for detecting recurrences in resected ampullary carcinomas (ACs). INTRODUCTION: Although an established prognostic marker for pancreatic ductal adenocarcinoma, the value of CA 19-9 in resected ACs during follow-up is unknown. METHODS: Retrospective analysis of ACs undergoing pancreaticoduodenectomy at Tata Memorial Centre-Mumbai, from January 2012 to January 2020 was performed. Survival, recurrence patterns, factors associated with recurrences and the utility of CA 19-9 surveillance were assessed. RESULTS: The 5-year OS of 572 included patients with ACs, was 56.4%. There were 251(43.88%) recurrences, majority being distant (n=223). Higher 'T' & 'N' stage, margin involvement, perineural invasion, poor tumour differentiation and pancreatobiliary subtype were associated with poor outcomes. Optimal CA 19-9 level to predict recurrence was 77.85 U/mL (sensitivity-61.22%, specificity-76.67%, AUC-0.711); however, a serial rise was a more accurate predictor (sensitivity-71.05%, specificity-91.67%). The median duration between the first rise in CA 19-9 (>37 U/mL) and radiological evidence of recurrence was 4.04 months. The optimal level of relative rise in CA 19-9 in diagnosing a recurrence was established at 2.79x (sensitivity-46.26%, specificity-83.33%, AUC-0.614). A serial rise and absolute value of >200 U/mL was associated with recurrence in 87% & 92.9% of cases. Recurrence detection & treatment after serum CA 19-9 elevation was associated with superior median survival as compared to recurrence detection without elevation (12.8 mo vs. 7.6 mo, P=0.005). CONCLUSION: Serum CA 19-9 testing during follow-up evaluation detects recurrences early and improves survival in resected ACs, and therefore should be recommended as a routine surveillance test.
RESUMO
BACKGROUND: Gallbladder cancers (GBCs) occur a decade earlier in India in comparison to the global occurrence, limiting the applicability of existing literature on age adjusted outcomes. METHODS: Patients who underwent surgery between 01.01.2010 and 31.12.2020 for GBC were analyzed. Patients were divided into three age groups: group 1(≤40 years), group 2(41-60 years), group 3(>60 years) and their outcomes were compared. RESULTS: Total of 6190 patients were treated for suspected or diagnosed GBC with a median age of 57 years. Curative resection was performed in 749 (67.9%) patients, of whom 114 (16.2%), 471 (62.9%), and 164 (21.9%) patients were in groups 1, 2, and 3, respectively. 5-year disease-free survival (DFS) [46.8% vs. 58.5%, p = 0.031] and overall survival (OS)[53.5% vs. 66.6%, p = 0.05] of group 3 were significantly lower than group 1. Patient age (HR 1.021), AJCC stage (HR 6.413), pathologic residual disease in the gallbladder fossa (HR 2.44), and extranodal tumor deposits (HR 1.762) were identified as independent predictors of poor OS. CONCLUSIONS: Gallbladder cancers in the Indian population show poorer outcomes with advancing age. Higher proportion of males in the elderly group with a more advanced stage at presentation are plausible reasons for poorer outcomes.
RESUMO
Intraoperative frozen section (FS) analysis to assess the bile duct margin status is commonly used to assess the completeness of resection during surgery for perihilar cholangiocarcinoma (pCCA) resection. However, the impact of additional re-section on the long-term outcome after obtaining an initial positive margin remains unclear. Patients diagnosed as pCCA on preoperative imaging and subjected to curative intent surgery from May 2013 to June 2021 with a minimum follow-up of 2 years were included. Intraoperative FS analysis of the proximal bile duct margin was performed in all patients. A positive margin was defined by the presence of invasive cancer. Out of the 62 patients with a preoperative diagnosis of pCCA on imaging, 35 patients were included for final analyses after excluding patients with inoperable disease (on staging laparoscopy or local exploration) and other/benign pathology on the final histopathology report. Out of the 35 patients, patients with postoperative 90-day mortality were excluded from the final survival analysis. FS analysis revealed an initial positive margin in 10 (28.5%) patients. Among 10 patients who underwent re-resection to achieve negative proximal margins, only 5 patients achieved a negative margin (secondary R0). An initial positive margin was associated with poor long-term outcomes. Median disease-free survival (DFS) and overall survival (OS) were 16 and 19.6 months for patients with an initial positive margin, but 36 and 58.2 months for patients with an initial negative margin, respectively (p = 0.012). The median DFS and OS were significantly lower for those with secondary R0 as compared to primary R0 (16 vs. 36 months for DFS, p = 0.117 and 19.6 vs. 58.2 months for OS, p = 0.027, respectively). An intraoperative FS positive proximal hepatic duct margin dictates poor long-term outcomes for patients with resectable pCCA. Additional resection has a questionable benefit on survival, when a secondary negative margin is achieved.
RESUMO
BACKGROUND: Radical resection remains the only potential cure in the management of inferior vena cava (IVC) leiomyosarcomas with multivisceral resections often needed (Borghi et al. in J Cardiovasc Surg (Torino) 63:649-663, 2022). This video describes the technical nuances of surgical resection of a large retrohepatic IVC leiomyosarcoma. PATIENT AND METHODS: Computed tomography of a 60-year-old woman revealed a 12 × 12 × 9.5 cm mass in the right suprarenal region infiltrating the IVC with intraluminal extension up to the hepatic venous confluence. The mass involved the right hepatic vein with infiltration of segment 7 of the liver and splaying of the right portal vein. Robust lumbar venous drainage from the infratumoral IVC was seen. En bloc IVC resection without reconstruction along with a right hepatectomy and right nephrectomy was performed via a right thoracoabdominal approach. RESULTS: After a Catell-Braasch maneuver, the surgery can be broadly divided into four major steps: (1) Right retroperitoneal mobilization of the tumor and right kidney with infratumoral IVC control, (2) mobilization of the right liver with suprahepatic IVC control, (3) division of the right portal structures with right hepatectomy, and (4) en bloc resection of the IVC tumor. Reconstruction of the IVC was not performed owing to the presence of venous collaterals (Langenbecks et al. in Arch Surg 407:1209-1216, 2022). Final histopathology showed a high-grade leiomyosarcoma with histologic organ invasion in the liver and right kidney with resected margins free of the tumor (R0). CONCLUSIONS: Meticulous preoperative planning and expertise in liver resection and retroperitoneal surgeries facilitates such radical yet safe multivisceral resection for a large retrohepatic IVC leiomyosarcoma without the need for a cardiopulmonary bypass.

BACKGROUND: Notable improvements in pancreatic cancer surgery have been due to utilization of the superior mesenteric artery (SMA)-first approach1 and triangle operation (clearance of triangle tissue between origin of SMA and celiac artery).2 The SMA-first approach was originally defined to assess resectability before taking the irreversible surgical steps. However, in the present era, resectability is judged by the preoperative radiology, and the benefit of the SMA-first approach is by improving the R0 resection rate and reducing blood loss. The basic principle is to identify the SMA at its origin and in the distal part, to guide the plane of uncinate dissection. This video demonstrates the combination of the posterior and right medial SMA-first approach along with triangle clearance during robotic pancreaticoduodenectomy (RPD). METHODS: The technique consisted of early dissection of SMA from the posterior aspect, by performing a Kocher maneuver using the 'posterior SMA-first approach'. The origin of the celiac artery, along with the SMA, was defined early in the surgery. During uncinate process dissection, the 'right/medial uncinate approach' was used to approach the SMA. 'Level 3 systematic mesopancreatic dissection' was performed along the SMA,3 culminating in the 'triangle operation'.2 RESULTS: The procedure was performed within 600 min, with a blood loss of 150 mL and no intraoperative or postoperative complications. The final histopathology report showed a moderately differentiated adenocarcinoma (pT2, pN2), with all resection margins free. CONCLUSION: The standardized technique of the SMA-first approach and triangle clearance during RPD is demonstrated in the video. Prospective studies should further evaluate the benefits of this procedure.

Paraganglioma is relatively rare retroperitoneal tumors. If functional retroperitoneal paragangliomas are misdiagnosed, surgical intervention can precipitate intraoperative hypertensive crises which may have serious consequences. We present a case of a 40-year-old female who presented with a large functional right-sided retroperitoneal paraganglioma encasing the inferior vena cava (IVC). The patient underwent paraganglioma excision with IVC resection with right nephrectomy. Such complex multivisceral resections require surgical expertise and are feasible at high-volume centers experienced in performing retroperitoneal surgeries.
