ABSTRACT
OBJECTIVE: To compare the outcomes of robotic minor liver resections (RMLR) versus laparoscopic (L) MLR of the anterolateral segments. BACKGROUND: Robotic liver surgery has been gaining prominence over the years with increasing usage for a myriad of hepatic resections. Robotic liver resections(RLR) has demonstrated non-inferiority to laparoscopic(L)LR while illustrating advantages over conventional laparoscopy especially for technically difficult and major LR. However, the advantage of RMLR for the anterolateral(AL) (segments II, III, IVb, V and VI) segments, has not been clearly demonstrated. METHODS: Between 2008 to 2022, 15,356 of 29,861 patients from 68 international centres underwent robotic(R) or laparoscopic minor liver resections (LMLR) for the AL segments Propensity score matching (PSM) analysis was performed for matched analysis. RESULTS: 10,517 patients met the study criteria of which 1,481 underwent RMLR and 9,036 underwent LMLR. A PSM cohort of 1,401 patients in each group were identified for analysis. Compared to the LMLR cohort, the RMLR cohort demonstrated significantly lower median blood loss (75ml vs. 100ml, P<0.001), decreased blood transfusion (3.1% vs. 5.4%, P=0.003), lower incidence of major morbidity (2.5% vs. 4.6%, P=0.004), lower proportion of open conversion (1.2% vs. 4.5%, P<0.001), shorter post operative stay (4 days vs. 5 days, P<0.001), but higher rate of 30-day readmission (3.5% vs. 2.1%, P=0.042). These results were then validated by a 1:2 PSM analysis. In the subset analysis for 3,614 patients with cirrhosis, RMLR showed lower median blood loss, decreased blood transfusion, lower open conversion and shorter post operative stay than LMLR. CONCLUSION: RMLR demonstrated statistically significant advantages over LMLR even for resections in the AL segments although most of the observed clinical differences were minimal.
ABSTRACT
OBJECTIVE: To compare the perioperative outcomes of robotic liver surgery (RLS) and laparoscopic liver surgery (LLS) in various settings. BACKGROUND: Clear advantages of RLS over LLS have rarely been demonstrated, and the associated costs of robotic surgery are generally higher than those of laparoscopic surgery. Therefore, the exact role of the robotic approach in minimally invasive liver surgery remains to be defined. METHODS: In this international retrospective cohort study, the outcomes of patients who underwent RLS and LLS for all indications between 2009 and 2021 in 34 hepatobiliary referral centers were compared. Subgroup analyses were performed to compare both approaches across several types of procedures: (1) minor resections in the anterolateral (2, 3, 4b, 5, and 6) or (2) posterosuperior segments (1, 4a, 7, 8), and (3) major resections (≥3 contiguous segments). Propensity score matching was used to mitigate the influence of selection bias. The primary outcome was textbook outcome in liver surgery (TOLS), previously defined as the absence of intraoperative incidents ≥grade 2, postoperative bile leak ≥grade B, severe morbidity, readmission, and 90-day or in-hospital mortality with the presence of an R0 resection margin in case of malignancy. The absence of a prolonged length of stay was added to define TOLS+. RESULTS: Among the 10.075 included patients, 1.507 underwent RLS and 8.568 LLS. After propensity score matching, both groups constituted 1.505 patients. RLS was associated with higher rates of TOLS (78.3% vs 71.8%, P < 0.001) and TOLS+ (55% vs 50.4%, P = 0.026), less Pringle usage (39.1% vs 47.1%, P < 0.001), blood loss (100 vs 200 milliliters, P < 0.001), transfusions (4.9% vs 7.9%, P = 0.003), conversions (2.7% vs 8.8%, P < 0.001), overall morbidity (19.3% vs 25.7%, P < 0.001), and microscopically irradical resection margins (10.1% vs. 13.8%, P = 0.015), and shorter operative times (190 vs 210 minutes, P = 0.015). In the subgroups, RLS tended to have higher TOLS rates, compared with LLS, for minor resections in the posterosuperior segments (n = 431 per group, 75.9% vs 71.2%, P = 0.184) and major resections (n = 321 per group, 72.9% vs 67.5%, P = 0.086), although these differences did not reach statistical significance. CONCLUSIONS: While both produce excellent outcomes, RLS might facilitate slightly higher TOLS rates than LLS.

OBJECTIVE: We aimed to establish global benchmark outcomes indicators for L-RPS/H67. BACKGROUND: Minimally invasive liver resections has seen an increase in uptake in recent years. Over time, challenging procedures as laparoscopic right posterior sectionectomies (L-RPS)/H67 are also increasingly adopted. METHODS: This is a post hoc analysis of a multicenter database of 854 patients undergoing minimally invasive RPS (MI-RPS) in 57 international centers in 4 continents between 2015 and 2021. There were 651 pure L-RPS and 160 robotic RPS (R-RPS). Sixteen outcome indicators of low-risk L-RPS cases were selected to establish benchmark cutoffs. The 75th percentile of individual center medians for a given outcome indicator was set as the benchmark cutoff. RESULTS: There were 573 L-RPS/H67 performed in 43 expert centers, of which 254 L-RPS/H67 (44.3%) cases qualified as low risk benchmark cases. The benchmark outcomes established for operation time, open conversion rate, blood loss ≥500 mL, blood transfusion rate, postoperative morbidity, major morbidity, 90-day mortality and textbook outcome after L-RPS were 350.8 minutes, 12.5%, 53.8%, 22.9%, 23.8%, 2.8%, 0% and 4% respectively. CONCLUSIONS: The present study established the first global benchmark values for L-RPS/H6/7. The benchmark provided an up-to-date reference of best achievable outcomes for surgical auditing and benchmarking.
ABSTRACT
BACKGROUND: Metabolic syndrome (MS) is rapidly growing as risk factor for HCC. Liver resection for HCC in patients with MS is associated with increased postoperative risks. There are no data on factors associated with postoperative complications. AIMS: The aim was to identify risk factors and develop and validate a model for postoperative major morbidity after liver resection for HCC in patients with MS, using a large multicentric Western cohort. MATERIALS AND METHODS: The univariable logistic regression analysis was applied to select predictive factors for 90 days major morbidity. The model was built on the multivariable regression and presented as a nomogram. Performance was evaluated by internal validation through the bootstrap method. The predictive discrimination was assessed through the concordance index. RESULTS: A total of 1087 patients were gathered from 24 centers between 2001 and 2021. Four hundred and eighty-four patients (45.2%) were obese. Most liver resections were performed using an open approach (59.1%), and 743 (68.3%) underwent minor hepatectomies. Three hundred and seventy-six patients (34.6%) developed postoperative complications, with 13.8% major morbidity and 2.9% mortality rates. Seven hundred and thirteen patients had complete data and were included in the prediction model. The model identified obesity, diabetes, ischemic heart disease, portal hypertension, open approach, major hepatectomy, and changes in the nontumoral parenchyma as risk factors for major morbidity. The model demonstrated an AUC of 72.8% (95% CI: 67.2%-78.2%) ( https://childb.shinyapps.io/NomogramMajorMorbidity90days/ ). CONCLUSIONS: Patients undergoing liver resection for HCC and MS are at high risk of postoperative major complications and death. Careful patient selection, considering baseline characteristics, liver function, and type of surgery, is key to achieving optimal outcomes.

BACKGROUND: The relation between operative time and postoperative complications in liver surgery is unclear. The aim of this study is to assess the impact of operative time on the development of postoperative complications in patients who underwent minimally invasive or open liver resections of various anatomical extent and technical difficulty levels. METHODS: In this retrospective cohort study, patients that underwent a right hemihepatectomy (RH), technically major resection (anatomically minor resection in segment 1, 4a, 7 or 8; TMR) or left lateral sectionectomy (LLS) between 2000 and 2022 were extracted from a multicenter database comprising the prospectively maintained databases of 31 centers in 13 countries. Minimally invasive procedures performed during the learning curve were omitted. Logistic regression models, performed separately for 9 different groups based on stratification by procedure type and allocated surgical approach, were used to assess the association between the fourth quartile of operative time (25% of patients with the longest operative time) and postoperative complications. RESULTS: Overall, 5424 patients were included: 1351 underwent RH (865 open, 373 laparoscopic and 113 robotic), 2821 TMR (1398 open, 1225 laparoscopic and 198 robotic), and 1252 LLS (241 open, 822 laparoscopic and 189 robotic). After adjusting for potential confounders (age, BMI, gender, ASA grade, previous abdominal surgery, disease type and extent, blood loss, Pringle, intraoperative transfusions and incidents), the fourth quartile of operative time, compared to the first three quartiles, was associated with an increased risk of postoperative complications after open, laparoscopic and robotic TMR (aOR 1.35, p = 0.031; aOR 1.74, p = 0.001 and aOR 3.11, p = 0.014, respectively), laparoscopic and robotic RH (aOR 1.98, p = 0.018 and aOR 3.28, p = 0.055, respectively) and solely laparoscopic LLS (aOR 1.69, p = 0.019). CONCLUSIONS: A prolonged operative time is associated with an increased risk of postoperative complications, although it remains to be defined if this is a causal relationship.
ABSTRACT
BACKGROUND: Solid benign liver lesions (BLL) are increasingly discovered, but clear indications for surgical treatment are often lacking. Concomitantly, laparoscopic liver surgery is increasingly performed. The aim of this study was to assess if the availability of laparoscopic surgery has had an impact on the characteristics and perioperative outcomes of patients with BLL. METHODS: This is a retrospective international multicenter cohort study, including patients undergoing a laparoscopic or open liver resection for BLL from 19 centers in eight countries. Patients were divided according to the time period in which they underwent surgery (2008-2013, 2014-2016, and 2017-2019). Unadjusted and risk-adjusted (using logistic regression) time-trend analyses were performed. The primary outcome was textbook outcome (TOLS), defined as the absence of intraoperative incidents ≥ grade 2, bile leak ≥ grade B, severe complications, readmission and 90-day or in-hospital mortality, with the absence of a prolonged length of stay added to define TOLS+. RESULTS: In the complete dataset comprised of patients that underwent liver surgery for all indications, the proportion of patients undergoing liver surgery for benign disease remained stable (12.6% in the first time period, 11.9% in the second time period and 12.1% in the last time period, p = 0.454). Overall, 845 patients undergoing a liver resection for BLL in the first (n = 374), second (n = 258) or third time period (n = 213) were included. The rates of ASA-scores≥3 (9.9%-16%,p < 0.001), laparoscopic surgery (57.8%-77%,p < 0.001), and Pringle maneuver use (33.2%-47.2%,p = 0.001) increased, whereas the length of stay decreased (5 to 4 days,p < 0.001). There were no significant changes in the TOLS rate (86.6%-81.3%,p = 0.151), while the TOLS + rate increased from 41.7% to 58.7% (p < 0.001). The latter result was confirmed in the risk-adjusted analyses (aOR 1.849,p = 0.004). CONCLUSION: The surgical treatment of BLL has evolved with an increased implementation of the laparoscopic approach and a decreased length of stay. This evolution was paralleled by stable TOLS rates above 80% and an increase in the TOLS + rate.

OBJECTIVE: To evaluate the effect of a liver transplantation (LT) program on the outcomes of resectable hepatocellular carcinoma (HCC). BACKGROUND: Surgical treatment of HCC includes both hepatic resection (HR) and LT. However, the presence of cirrhosis and the possibility of recurrence make the management of this disease complex and probably different according to the presence of a LT program. METHODS: Patients undergoing HR for HCC between January 2005 and December 2019 were identified from a national database of HCC. The main study outcomes were major surgical complications according to the Comprehensive Complication Index, posthepatectomy liver failure (PHLF), 90-day mortality, overall survival, and disease-free survival. Secondary outcomes were salvage liver transplantation (SLT) and postrecurrence survival. RESULTS: A total of 3202 patients were included from 25 hospitals over the study period. Three of 25 (12%) had an LT program. The presence of an LT program within a center was associated with a reduced probability of PHLF (odds ratio=0.38) but not with overall survival and disease-free survival. There was an increased probability of SLT when HR was performed in a transplant hospital (odds ratio=12.05). Among transplant-eligible patients, those who underwent LT had a significantly longer postrecurrence survival. CONCLUSIONS: This study showed that the presence of a LT program was associated with decreased PHLF rates and an increased probability to receive SLT in case of recurrence.

BACKGROUND: Consensus on the best surgical strategy for the management of synchronous colorectal liver metastases (sCRLM) has not been achieved. This study aimed to assess the attitudes of surgeons involved in the treatment of sCRLM. METHODS: Surveys designed for colorectal, hepato-pancreato-biliary (HPB), and general surgeons were disseminated through representative societies. Subgroup analyses were performed to compare responses between specialties and continents. RESULTS: Overall, 270 surgeons (57 colorectal, 100 HPB and 113 general surgeons) responded. Specialist surgeons more frequently utilized minimally invasive surgery (MIS) than general surgeons for colon (94.8% vs. 71.7%, p < 0.001), rectal (91.2% vs. 64.6%, p < 0.001), and liver resections (53% vs. 34.5%, p = 0.005). In patients with an asymptomatic primary, the liver-first two-stage approach was preferred in most respondents' centres (59.3%), while the colorectal-first approach was preferred in Oceania (83.3%) and Asia (63.4%). A substantial proportion of the respondents (72.6%) had personal experience with minimally invasive simultaneous resections, and an expanding role for this procedure was foreseen (92.6%), while more evidence was desired (89.6%). Respondents were more reluctant to combine a hepatectomy with low anterior (76.3%) and abdominoperineal resections (73.3%), compared to right (94.4%) and left hemicolectomies (90.7%). Colorectal surgeons were less inclined to combine right or left hemicolectomies with a major hepatectomy than HPB and general surgeons (right: 22.8% vs. 50% and 44.2%, p = 0.008; left: 14% vs. 34% and 35.4%, p = 0.002, respectively). CONCLUSION: The clinical practices and viewpoints on the management of sCRLM differ between continents, and between and within surgical specialties. However, there appears to be consensus on a growing role for MIS and a need for evidence-based input.

BACKGROUND: The European registry for minimally invasive pancreatic surgery (E-MIPS) collects data on laparoscopic and robotic MIPS in low- and high-volume centers across Europe. METHODS: Analysis of the first year (2019) of the E-MIPS registry, including minimally invasive distal pancreatectomy (MIDP) and minimally invasive pancreatoduodenectomy (MIPD). Primary outcome was 90-day mortality. RESULTS: Overall, 959 patients from 54 centers in 15 countries were included, 558 patients underwent MIDP and 401 patients MIPD. Median volume of MIDP was 10 (7-20) and 9 (2-20) for MIPD. Median use of MIDP was 56.0% (IQR 39.0-77.3%) and median use of MIPD 27.7% (IQR 9.7-45.3%). MIDP was mostly performed laparoscopic (401/558, 71.9%) and MIPD mostly robotic (234/401, 58.3%). MIPD was performed in 50/54 (89.3%) centers, of which 15/50 (30.0%) performed ≥20 MIPD annually. This was 30/54 (55.6%) centers and 13/30 (43%) centers for MIPD respectively. Conversion rate was 10.9% for MIDP and 8.4% for MIPD. Overall 90 day mortality was 1.1% (n = 6) for MIDP and 3.7% (n = 15) for MIPD. CONCLUSION: Within the E-MIPS registry, MIDP is performed in about half of all patients, mostly using laparoscopy. MIPD is performed in about a quarter of patients, slightly more often using the robotic approach. A minority of centers met the Miami guideline volume criteria for MIPD.

BACKGROUND: Despite second-line transplant(SLT) for recurrent hepatocellular carcinoma(rHCC) leads to the longest survival after recurrence(SAR), its real applicability has never been reported. The aim was to compare the SAR of SLT versus repeated hepatectomy and thermoablation(CUR group). METHODS: Patients were enrolled from the Italian register HE.RC.O.LE.S. between 2008 and 2021. Two groups were created: CUR versus SLT. A propensity score matching (PSM) was run to balance the groups. RESULTS: 743 patients were enrolled, CUR = 611 and SLT = 132. Median age at recurrence was 71(IQR 6575) years old and 60(IQR 53-64, p < 0.001) for CUR and SLT respectively. After PSM, median SAR for CUR was 43 months(95%CI = 37 - 93) and not reached for SLT(p < 0.001). SLT patients gained a survival benefit of 9.4 months if compared with CUR. MilanCriteria(MC)-In patients were 82.7% of the CUR group. SLT(HR 0.386, 95%CI = 0.23 - 0.63, p < 0.001) and the MELD score(HR 1.169, 95%CI = 1.07 - 1.27, p < 0.001) were the only predictors of mortality. In case of MC-Out, the only predictor of mortality was the number of nodules at recurrence(HR 1.45, 95%CI= 1.09 - 1.93, p = 0.011). CONCLUSION: It emerged an important transplant under referral in favour of repeated hepatectomy or thermoablation. In patients with MC-Out relapse, the benefit of SLT over CUR was not observed.

BACKGROUND: We aimed to evaluate, in a large Western cohort, perioperative and long-term oncological outcomes of salvage hepatectomy (SH) for recurrent hepatocellular carcinoma (rHCC) after primary hepatectomy (PH) or locoregional treatments. METHODS: Data were collected from the Hepatocarcinoma Recurrence on the Liver Study Group (He.RC.O.Le.S.) Italian Registry. After 1:1 propensity score-matched analysis (PSM), two groups were compared: the PH group (patients submitted to resection for a first HCC) and the SH group (patients resected for intrahepatic rHCC after previous HCC-related treatments). RESULTS: 2689 patients were enrolled. PH included 2339 patients, SH 350. After PSM, 263 patients were selected in each group with major resected nodule median size, intraoperative blood loss and minimally invasive approach significantly lower in the SH group. Long-term outcomes were compared, with no difference in OS and DFS. Univariate and multivariate analyses revealed only microvascular invasion as an independent prognostic factor for OS. CONCLUSION: SH proved to be equivalent to PH in terms of safety, feasibility and long-term outcomes, consistent with data gathered from East Asia. In the awaiting of reliable treatment-allocating algorithms for rHCC, SH appears to be a suitable alternative in patients fit for surgery, regardless of the previous therapeutic modality implemented.

BACKGROUND: Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined. METHODS: Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3). RESULTS: A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups). CONCLUSION: We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

INTRODUCTION: Postoperative pancreatic fistula (POPF) following distal pancreatectomy (DP) remains the most frequent complication, potential precursor of more serious events, and mechanisms behind POPF development are not clear. Primary aim of the current study is to investigate correlations between patients' characteristics, including technical intraoperative data assessed by retrospective video review of laparoscopic DP (L-PD), and development of clinically relevant (CR-)POPF and major complication. METHODS: Patients undergoing L-DP whose surgery video was available for review were included in this study. Retrospective video review, performed by two surgeons blinded for postoperative outcomes, was focused on pancreatic neck transection and identification of pancreatic capsule disruption (PCD)/staple line bleeding (SLB). Correlation between clinical, demographic, and intraoperative factors and CR-POPF/major complications and assessment of factors associated with PCD and SLB were investigated. RESULTS: Of 41 L-DP performed at our institution (June 2015-June 2020) using a triple-row stapler (EndoGIA™ Reloads with Tri-Staple™), surgery video was available for 38 patients [men/women, 13/25; median age (range) 62 (25-84) years; median BMI (range) 24 (17-42)]. PCD and SLB occurred in 15(39%) and 19(50%) patients and were concomitant in 9(24%). CR-POPF and major complications occurred in 8(21%) and 12(31%) patients, respectively. PCD, SLB, and PCD + SLB rates were significantly higher among patients with CR-POPF, compared to patients without (all p < 0.05). Among patients with PCD, pancreatic thickness at pancreatic transection site was higher (19 mm), compared to non-PCD patients (13 mm, p < 0.001). A directly proportional relation between PCD, CR-POPF, and major complication rate and pancreatic thickness was confirmed by ROC analysis (AUC = 0.949, 0.798, and 0.740, respectively). CONCLUSION: PCD and SLB close to the staple line detected by retrospective video-review are intraoperatively detectable indicators of severe pancreatic traumatism and a potential precursors of CR-POPF following L-PD. Given the strict correlation between PCD and pancreatic thickness, alternative techniques to stapled closure for pancreatic transection may be recommended for patients with a thick pancreas and modification in postoperative care may be considered in patients with PCD/SLB.

BACKGROUND: Management of recurrence after surgery for hepatocellular carcinoma (rHCC) is still a debate. The aim was to compare the Survival after Recurrence (SAR) of curative (surgery or thermoablation) versus palliative (TACE or Sorafenib) treatments for patients with rHCC. METHODS: This is a multicentric Italian study, which collected data between 2007 and 2018 from 16 centers. Selected patients were then divided according to treatment allocation in Curative (CUR) or Palliative (PAL) Group. Inverse Probability Weighting (IPW) was used to weight the groups. RESULTS: 1,560 patients were evaluated, of which 421 experienced recurrence and were then eligible: 156 in CUR group and 256 in PAL group. Tumor burden and liver function were weighted by IPW, and two pseudo-population were obtained (CUR = 397.5 and PAL = 415.38). SAR rates at 1, 3 and 5 years were respectively 98.3%, 76.7%, 63.8% for CUR and 91.7%, 64.2% and 48.9% for PAL (p = 0.007). Median DFS was 43 months (95%CI = 32-74) for CUR group, while it was 23 months (95%CI = 18-27) for PAL (p = 0.017). Being treated by palliative approach (HR = 1.75; 95%CI = 1.14-2.67; p = 0.01) and having a median size of the recurrent nodule>5 cm (HR = 1.875; 95%CI = 1.22-2.86; p = 0.004) were the only predictors of mortality after recurrence, while time to recurrence was the only protective factor (HR = 0.616; 95%CI = 0.54-0.69; p<0.001). CONCLUSION: Curative approaches may guarantee long-term survival in case of recurrence.

OBJECTIVE: The aim of this study was to evaluate correlation between centers' volume and incidence of failure to rescue (FTR) following liver resection for hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: FTR, defined as the probability of postoperative death among patients with major complication, has been proposed to assess quality of care during hospitalization. Perioperative management is challenging in cirrhotic patients and the ability to recognize and treat a complication may be fundamental to rescue patients from the risk of death. METHODS: Patients undergoing liver resection for HCC between 2008 and 2018 in 18 Centers enrolled in the He.Rc.O.Le.S. Italian register. Early results included major complications (Clavien ≥3), 90-day mortality, and FTR and were analyzed according to center's volume. RESULTS: Among 1935 included patients, major complication rate was 9.4% (8.6%, 12.3%, and 7.0% for low-, intermediate- and high-volume centers, respectively, P = 0.001). Ninety-day mortality rate was 2.6% (3.7%, 4.2% and 0.9% for low-, intermediate- and high-volume centers, respectively, P < 0.001). FTR was significantly higher at low- and intermediate-volume centers (28.6% and 26.5%, respectively) than at high-volume centers (6.1%, P = 0.002). Independent predictors for major complications were American Society of Anesthesiologists (ASA) >2, portal hypertension, intraoperative blood transfusions, and center's volume. Independent predictors for 90-day mortality were ASA >2, Child-Pugh score B, BCLC stage B-C, and center's volume. Center's volume and BCLC stage were strongly associated with FTR. CONCLUSIONS: Risk of major complications and mortality was related with comorbidities, cirrhosis severity, and complexity of surgery. These factors were not correlated with FTR. Center's volume was the only independent predictor related with severe complications, mortality, and FTR.

BACKGROUND: It has recently been shown that the 'triangle operation'1 may be associated with margin-free resection in selected patients with borderline resectable pancreatic cancer after neoadjuvant chemotherapy. Such a procedure consists of en bloc removal, following the adventitial plane of the whole mesopancreas from the triangular space delimited by the superior mesenteric artery, hepatic artery, and portal vein.2-11 In this video, we show how to safely perform this procedure by laparoscopy. METHODS: A 70-year-old male with persistent back pain and significant loss of weight underwent a computed tomography that showed a 3 cm mass of the uncinate process of the pancreas with involvement of the superior mesenteric artery and venous axis. The biopsy, performed at the time of endoscopic retrograde cholangiopancreatography, showed an adenocarcinoma of the pancreas. Cancer antigen (CA) 19-9 was in the normal range. The patient received eight cycles of neoadjuvant chemotherapy (FOLFIRINOX). The chemotherapy induced a major tumoral radiological response with tumoral shrinkage, however the preoperative computed tomography showed persistent infiltration of the mesopancreas behind the superior mesenteric artery and venous axis. A radical laparoscopic pancreaticoduodenectomy with portal vein resection was performed, including the complete clearing of the superior mesenteric artery and the right side of the celiac trunk, as in the 'triangle operation'. Venous reconstruction was achieved with an end-to-end 5/0 polypropylene running suture with growth factor, while intestinal reconstruction was achieved with an end-to-side hepaticojejunal anastomosis, a double purse-string pancreaticogastrostomy, and side-to-side mechanical linear gastrojejunostomy. The specimen was removed via a short Pfannenstiel incision. RESULTS: Operative time was 7 h and 15 min, and blood loss was 150. Frozen sections of the superior mesenteric artery margins were negative for tumoral cells. On postoperative day 5, the patient had a hematemesis with bleeding from the pancreaticogastrostomy, which was treated endoscopically. Hospital stay was 16 days. Histopathological examination showed a well-differentiated adenocarcinoma of the pancreas [ypT3 N1 (3/36) R0]. CONCLUSION: The 'triangle operation' for borderline resectable pancreatic head cancer can be achieved safely by laparoscopy in carefully selected patients.1-11 Proven experience in both open and laparoscopic pancreatic surgery is mandatory.

BACKGROUND: Due to its technical complexity, laparoscopic (L-) radical antegrade modular pancreatosplenectomy (RAMPS) for left-sided pancreatic ductal adenocarcinoma (PDAC) has been described in a few series.1-4 In addition, splenomesenteric junction tumor involvement is considered a formal contraindication to L-RAMPS. METHODS: The video shows posterior L-RAMPS with a left approach to the superior mesenteric artery (SMA) for a left-sided PDAC with suspected involvement of the splenomesenteric junction. RESULTS: The patient was a 61-year-old woman affected by a cT3N0M0 pancreatic body PDAC. Following dissection of the superior mesenteric vein (SMV), proper/common hepatic artery, and gastroduodenal artery, the pancreatic neck is encircled and the celiac trunk (CT) skeletonized. The treitz ligament is opened, and the SMA is identified and dissected on its left anterior margin. Pancreatic mobilization en bloc with the Gerota fascia and left adrenal gland is followed by splenic artery transection and suprapancreatic lymphadenectomy completion. The mesopancreas is dissected from the right margin of the SMA and CT and the pancreas is transected. The portal vein and SMV are cross-clamped and a venous tangential resection/closure is performed. Cryostate histological examination of the venous and pancreatic stumps showed absence of tumor cells. Final pathology revealed a pT2N0(0+/42)R0G2 PDAC of the pancreatic body. CONCLUSION: During L-RAMPS, periadvential SMA dissection through the left-anterior approach, specular to the right posterior SMA approach described for laparoscopic pancreatoduodenectomy,5,6 has a primary role in maximizing the vascular surgical margin and, allowing for complete mobilization of the specimen before vein resection, may make a splenomesenteric junction tangential resection/closure easier and safer in case of tumor involvement of the splenomesenteric venous axis.

Adult intussusception of the bowel is a rare clinical entity, and its management remains debated. The timing of treatment is not yet standardised, and no guidelines exist. We report a case of an 83-year-old woman presenting to the emergency department of our hospital with a history of increasing abdominal pain in the right iliac fossa. A contrast-enhanced computed tomography scan showed the presence of a large ileocolic intussusception with evidence of the terminal ileus invaginated within the right colon and the ileocolic vessels dragged and trapped into the intussusception. A colonoscopy confirmed the ileocolic invagination with a large right colonic lesion as leading point, and a partial pneumatic (carbon dioxide) and hydrostatic reduction was achieved. Subsequent laparoscopic right colectomy was performed according to oncological principles. A totally minimally invasive approach of this rare condition has been achieved but the literature lacks about the correct management of this entity.

BACKGROUND: The prognosis of patients affected by pancreatic adenocarcinoma and periampullary tumors is dismal, mainly due to aggressive tumor biology and low rate of resectability at the diagnosis. Among resectable patients, the quality of surgical resection, with a particular focus on the complete resection of the retropancreatic tissue (the so-called "mesopancreas") encircling the superior mesenteric artery (SMA), has a cardinal role. With this assumption, many pancreatic surgeons recommend periadventitial dissection of the SMA in order to obtain a total mesopancreas excision (TMpE), maximizing surgical margin and minimizing R1 resection rate. OBJECTIVE: To introduce our approaches for periadventitial dissection of the SMA, tailored to patient and tumor characteristics and aiming at obtaining a TMpE, during laparoscopic pancreatoduodenectomy (LPD). METHODS: Three different approaches for the SMA periadventitial dissection during LPD are described: the right, the right-left, and the anterior SMA-first approach. Indications, advantages, and technical aspects of each technique are reported, as well as pathologic results, particularly focusing on resection margin status and removed lymphnodes number, safety, and feasibility. RESULTS: Overall, R0 rate and number of lymphnodes retrieved were 86% and 26, respectively, without significant differences according to the SMA approach performed. Rate of conversion to laparotomy due to intraoperative bleeding during SMA dissection step was 6% (3/48) among patients who underwent the right SMA approach and nil among remaining patients. CONCLUSION: During LPD, a tailored approach for periadventitial dissection of SMA makes TMpE feasible, safe, and oncologic valid, when performed by a team experienced with mininvasive approach and pancreatic surgery.
