ABSTRACT
BACKGROUND AND AIMS: Alterations in liver histology influence the liver's capacity to regenerate, but the relevance of each of the different changes in rapid liver growth induction is unknown. This study aimed to analyze the influence of the degree of histological alterations during the first and second stages on the ability of the liver to regenerate. METHODS: This cohort study included data obtained from the International ALPPS Registry between November 2011 and October 2020. Only patients with colorectal liver metastases were included in the study. We developed a histological risk score based on histological changes (stages 1 and 2) and a tumor pathology score based on the histological factors associated with poor tumor prognosis. RESULTS: In total, 395 patients were included. The time to reach stage 2 was shorter in patients with a low histological risk stage 1 (13 vs 17 days, P Ë0.01), low histological risk stage 2 (13 vs 15 days, P <0.01), and low pathological tumor risk (13 vs 15 days, P <0.01). Regarding interval stage, there was a higher inverse correlation in high histological risk stage 1 group compared to low histological risk 1 group in relation with future liver remnant body weight ( r =-0.1 and r =-0.08, respectively), and future liver remnant ( r =-0.15 and r =-0.06, respectively). CONCLUSIONS: ALPPS is associated with increased histological alterations in the liver parenchyma. It seems that the more histological alterations present and the higher the number of poor prognostic factors in the tumor histology, the longer the time to reach the second stage.

BACKGROUND: Postoperative complications after perihilar cholangiocarcinoma surgical procedure are still very high. The implementation of a multimodal prehabilitation program could improve these outcomes. Based on our experience and that of the literature in hepatobiliary and pancreatic surgery, we propose a protocol to promote its implementation. METHODS: First, we performed a retrospective analysis of the implementation feasibility of a multimodal prehabilitation program in patients' candidates for elective perihilar cholangiocarcinoma surgery in our center. Second, we conducted a literature search of publications in PubMed until December 2022. Relevant data about hepato-pancreato-biliary surgery and prehabilitation programs in features and postoperative outcomes was analyzed. RESULTS: Since October 2020, 11 patients were evaluated for prehabilitation in our hospital. Two of them could not be resected intraoperatively due to disease extension. The median hospital stay was 10 days (iqr, 7-11). There were no major complications and 1 patient died. Of a total of 17 articles related to prehabilitation in hepato-biliary-pancreatic surgery, no reports focusing exclusively on perihilar cholangiocarcinoma were found. Six of the studies had nutritional therapies in addition to physical interventions, and 12 studies used home-based exercise therapy. CONCLUSIONS: Based on our experience and the data obtained from other studies, a prehabilitation program could be useful to improve perioperative physical and mental fitness in patients' candidates for elective perihilar cholangiocarcinoma surgery. However, more well-designed studies are needed to allow us to obtain more evidence.

BACKGROUND: Studies comparing hand-assisted laparoscopic (HALS)/Hybrid and pure laparoscopic (PLS) resection for colorectal cancer liver metastasis have focused on short-term results, while long-term oncological outcomes remain understudied. METHODS: We established a multi-institutional retrospective cohort study from four centers with experience in minimally invasive surgery between 2004 and 2020. Primary endpoints were overall survival (OS) and disease-free survival (DFS). Other endpoints analyzed were intraoperative and postoperative outcomes. Propensity score matching (PSM) was used to minimize baseline differences. RESULTS: A total of 219 HALS/Hybrid (57.8%) and 160 PLS (42.2%) patients were included. After PSM, 155 patients remained in each group. Operative time (182 vs. 248 min, p = 0.012), use of intraoperative ablation (12.3 vs. 4.5%, p = 0.024), positive resection margin (4.5 vs 13.2%, p = 0.012), and pringle time (21 vs. 37 min, p = 0.001) were higher in PLS group. DFS at 1, 3, 5, and 7 years in HALS/Hybrid and PLS groups were 65.4%, 39.3%, 37.5%, and 36.3% vs. 64.9%, 38.0%, 33.1%, and 33.1%, respectively (p = 0.84). OS at 1, 3, 5, and 7 years in HALS/Hybrid and PLS groups were 94.5%, 71.4%, 54.3%, and 46.0% vs. 96.0%, 68.5%, 51.2%, and 41.2%, respectively (p = 0.73). CONCLUSION: Our study suggests no differences in long-term oncologic outcomes between the two techniques. We discovered that longer total operative, pringle time, higher rates of intraoperative ablation, and positive resection margins were associated with PLS. These differences in favor of HALS/Hybrid could be due to a shorter learning curve and a greater ability to control hemorrhage.

BACKGROUND: It is not known if the inflammatory phenomena related to highly accelerated regeneration activate any signaling pathways that are associated with a major stimulus to colorectal liver metastases (CRLM) disease in tourniquet associating liver partition and portal vein ligation for staged hepatectomy (T-ALPPS) compared to two stage hepatectomy (TSH). METHODS: Between January 2012 and April 2018, we prospectively performed biopsies from future liver remnant and deportalized lobe in CRLM patients undergoing T-ALPPS in both stages. Immunohistopathological analysis was performed on the above tissue samples and compared to biopsy samples from patients who underwent TSH for CRLM at our center between September 2000 and August 2011. RESULTS: A total of 42 patients (20 TSH and 22 T-ALPPS) were included. There were no differences in the rates of recurrence, overall survival or any of the factors analyzed relating to tumor progression between stages 1 and 2. Regarding the anti-tumor effect, there was a significant reduction in the number of T-CD8 infiltrates in the second stage of TSH (12.5 vs. 5.5, p = 0.02). CONCLUSION: The results suggest that liver regeneration with T-ALPPS does not induce higher tumor progression or significant immunological changes in the tumor environment when compared to classical TSH.

BACKGROUND: While ALPPS triggers a fast liver hypertrophy, it is still unclear which factors matter most to achieve accelerated hypertrophy within a short period of time. The aim of the study was to identify patient-intrinsic factors related to the growth of the future liver remnant (FLR). METHODS: This cohort study is composed of data derived from the International ALPPS Registry from November 2011 and October 2018. We analyse the influence of demographic, tumour type and perioperative data on the growth of the FLR. The volume of the FLR was calculated in millilitre and percentage using computed-tomography (CT) scans before and after stage 1, both according to Vauthey formula. RESULTS: A total of 734 patients were included from 99 centres. The median sFLR at stage 1 and stage 2 was 0.23 (IQR, 0.18-0.28) and 0.39 (IQR: 0.31-0.46), respectively. The variables associated with a lower increase from sFLR1 to sFLR2 were ageË68 years (p = .02), height Ë1.76 m (p Ë .01), weight Ë83 kg (p Ë .01), BMIË28 (p Ë .01), male gender (p Ë .01), antihypertensive therapy (p Ë .01), operation time Ë370 minutes (p Ë .01) and hospital stayË14 days (p Ë .01). The time required to reach sufficient volume for stage 2, male gender accounts 40.3% in group Ë7 days, compared with 50% of female, and female present 15.3% in group Ë14 days compared with 20.6% of male. CONCLUSIONS: Height, weight, FLR size and gender could be the variables that most constantly influence both daily growths, the interstage increase and the standardized FLR before the second stage.

BACKGROUND: Laparoscopic liver resection of tumors located in segments 7 and 8 are considered a complex resection. The aim of this study was to compare the intraoperative and early postoperative outcomes of patients operated by pure laparoscopic (PLS) vs hand-assisted laparoscopic surgery (HALS). METHODS: From January 2003 to January 2021, we included patients with minimally invasive surgery for lesions located in segments 7 and 8. To overcome selection bias, we performed 1:1 propensity score matching (PSM) between HALS and PLS cohorts, including 30 patients in each of the groups. Of the 60 patients who underwent PSM, we compared the first 30 patients with the following 30 patients. RESULTS: A total of 79 LLRs were performed, 46 by HALS and 33 by PLS. After PSM, in the PLS cohort, cirrhosis was more frequent (33.3% vs. 13.3%, p = 0.02). The surgical time, blood loss, Pringle maneuver, clamping time, and morbidity were similar between both groups, but with a lower hospital stay in the PLS group (3 days vs. 4 days, p < 0.01). In the first 30 patients who underwent LLR, the use of PLS was lower than the use of HALS, increasing due to the learning curve (16.7% in the first period vs. 83.3% in the second period; p < 0.01). The hospital stay was lower in the second period due to the more frequent use of PLS (3 vs. 4 days, p < 0.01). CONCLUSION: PLS presents similar intraoperative and early postoperative results with lower hospital stay for lesions located in segments 7 and 8 compared to HALS. In centers with experience in LLRs, PLS could be performed safely in these segments.

PURSPOSE: Iatrogenic bile duct injuries (IBDI) with intrahepatic involvement are a serious and challenging surgical complication that can have disastrous consequences in terms of morbidity and mortality. METHODS: We collected the patients with IBDI type (E4) between January 1991 and March 2020 in our hospital. The objective of the study was to present the long-term results of a extraglissonian approach and intraglissonian biliary reconstruction in a series of patients with intrahepatic bile duct injuries after cholecystectomy. We also detail our preoperative management and the standardization of the technique. RESULTS: An extraglissonian approach with partial hepatic resection of the base of segments 4b and 5 and intraglissonian Roux-en-Y hepaticojejunostomy for biliary reconstruction using to several branches was performed in 10 patients with E4 Strassberg type intrahepatic lesions. Only one patient had postoperative bile leak (Clavien 3a). Surgical time was 260 min (IQR, 210-490). We left transanastomotic catheter (between 2 and 5) in situ for 3 and 6 months after surgery. The patients remained asymptomatic over a median follow-up of 169 months (IQR 129-234). CONCLUSION: This biliary reconstruction technique obtains positive long-term outcomes in patients with severe intrahepatic lesions.

PURPOSE: Assessing hepatic vein reconstruction using a left renal vein graft and in situ hypothermic liver perfusion in an extended liver resection. METHODS: Patients included in this study were those with liver tumors undergoing curative surgery with resection and reconstruction of hepatic veins. Hepatic vein was reconstructed using a left renal vein graft. We describe the technical aspects of liver resection and vascular reconstruction, the key aspects of hemodynamic management, and the use of in situ hypothermic liver preservations during liver transection (prior to and during vascular clamping). RESULTS: The right hepatic vein was reconstructed with a median left renal venal graft length of 4.5 cm (IQR, 3.1-5.2). Creatinine levels remained within normal limits in the immediate postoperative phase and during follow-up. Median blood loss was 500 ml (IQR, 300-1500) and in situ perfusion with cold ischemia was 67 min (IQR, 60.5-77.5). The grafts remained patent during the follow-up with no signs of thrombosis. No major postoperative complications were observed. CONCLUSION: Left renal vein graft for the reconstruction of a hepatic vein and in situ hypothermic liver perfusion are feasible during extended liver resection.

OBJECTIVE: We present a new variant of partial-ALPPS (p-ALPPS) "Tourniquet partial-ALPPS (Tp-ALPPS)", with the aim of reducing aggressiveness during stage 1. SUMMARY BACKGROUND DATA: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) results in liver regeneration in only 9 days. Due to its high initial morbidity and mortality, less aggressive variants were designed. METHODS: A new surgical variant of ALPPS was designed consisting in introducing a Kelly forceps from the base of the liver, crossing the liver parenchyma through an avascular area. A 3-mm Vicryl (V152; Ethicon, Somerville, New Jersey, USA) tape is passed, and the tourniquet is then knotted. Six patients operated on by this new Tp-ALPPS surgical technique were compared to 6 patients operated on by Tourniquet ALPPS (T-ALPPS). RESULTS: There were no differences in volume increase at 10 days. During stage 1, blood losses and transfusion rates tended to be lower in the Tp-ALPPS group, without statistical differences. Surgical time was shorter in the Tp-ALPPS group than in T-ALPPS (90âmin versus 135 min) (p < 0.023). In stage 2, blood losses and transfusion were similar in both groups, but surgical time tended to be higher in the Tp-ALPPS group, which could be related to the surgical technique performed. There were no differences in morbidity and mortality. CONCLUSIONS: Tp-ALPPS achieved a similar increase in volume as T-ALPPS but with a shorter stage 1 surgical and similar morbidity and mortality.

PURPOSE: Laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) offers better short-term results than open surgery with similar long-term results although it is technically difficult due to the risk of bleeding. METHODS: This study included patients with HCC in Child A cirrhosis who underwent TACE before LLR between 2009 and 2019. The primary endpoint was to analyze the intraoperative and early results of this technique. We also analyzed the long-term outcomes. Patients with and without clinically significant portal hypertension (CSPH) were compared. RESULTS: A total of 44 cirrhotic patients with HCC were included (24 CSPH and 20 non-CSPH). The Pringle maneuver was used in two cases (4.5%), mean blood losses was 100 ml (range 50-200), and three patients (6.8%) required a blood transfusion. The degree of necrosis achieved was greater than 90% in 27 patients (61.4%). At 1, 3, and 5 years, overall survival was 97.7%, 81.5%, and 63.4%, respectively, and disease-free survival was 85.2%, 52.5%, and 34.5%, respectively. There were no statistically significant differences between non-CSPH and CSPH groups regarding intraoperative, early, and long-term outcomes. CONCLUSION: In our experience, TACE could be beneficial to perform LLR in HCC Child-Pugh A patients with and without CSPH without serious complications and similar oncological outcomes.

BACKGROUND: Hepatobiliary resections are challenging due to the complex liver anatomy. Three-dimensional printing (3DP) has gained popularity due to its ability to produce anatomical models based on the characteristics of each patient. METHODS: A multicenter study was conducted on complex hepatobiliary tumours. The endpoint was to validate 3DP model accuracy from original image sources for application in the teaching, patient-communication, and planning of hepatobiliary surgery. RESULTS: Thirty-five patients from eight centers were included. Process testing between 3DP and CT/MRI presented a considerable degree of similarity in vascular calibers (0.22 ± 1.8 mm), and distances between the tumour and vessel (0.31 ± 0.24 mm). The Dice Similarity Coefficient was 0.92, with a variation of 2%. Bland-Altman plots also demonstrated an agreement between 3DP and the surgical specimen with the distance of the resection margin (1.15 ± 1.52 mm). Professionals considered 3DP at a positive rate of 0.89 (95%CI; 0.73-0.95). According to student's distribution a higher success rate was reached with 3DP (median:0.9, IQR: 0.8-1) compared with CT/MRI or 3D digital imaging (P = 0.01). CONCLUSION: 3DP hepatic models present a good correlation compared with CT/MRI and surgical pathology and they are useful for education, understanding, and surgical planning, but does not necessarily affect the surgical outcome.

OBJECTIVE: To present surgical and oncological outcomes using a prospective and randomized trial (LapOpHuva, NCT02727179) comparing minimally invasive liver resection (LLR) versus open liver resection (OLR) in patients with colorectal liver metastases (CRLM). METHODS: Between February 2005 and March 2016, 204 selected patients with CRLM were randomized and 193 were included: LLR (n = 96) and OLR (n = 97). The primary endpoint was to compare postoperative morbidity. Other secondary endpoints were oncological outcomes, use of the Pringle maneuver, surgical time, blood losses, transfusions, hospital stay, mortality and OS, and disease-free survival (DFS) at 3, 5, and 7 years. RESULTS: LLR presented with lower global morbidity (11.5% vs. 23.7%, p = 0.025) but with similar severe complications. Long-term survival outcomes were similar in both groups. The cumulative 1-, 3-, 5-, 7-year OS for LLR and OLR were 92.5%, 71.5%, 49.3%, 35.6% versus 93.6%, 69.7%, 47.4%, 35.5%, respectively (log-rank = 0.047, p = 0.82). DFS for LLR and OLR was 72.7%, 33.5%, 22.7%, and 20.8% versus 61.6%, 27.2%, 23.9%, and 17.9%, respectively (log-rank = 1.427, p = 0.23). LLR involved more use of the Pringle maneuver (15.5% vs. 30.2%, p = 0.025) and a shorter hospital stay (4 vs. 6 days, p < 0.001). There were no differences regarding surgical time, blood losses, transfusion, and mortality. CONCLUSIONS: In selected patients with CRLM, LLR presents similar oncological outcomes with the advantages of the short-term results associated with LLR.

BACKGROUND: To compare the overall survival (OS) and disease-free survival (DFS) of Tourniquet-ALPPS (T-ALPPS) and conventional two-stage hepatectomy (TSH) in patients with colorectal liver metastases (CRLM). METHODS: A retrospective study from a prospectively collected database was performed between October 2000 and July 2016. TSH was performed before September 2011, after which time T-ALPPS became the technique of choice. A propensity score matching (PSM) was performed based on a 1:1 ratio with consideration of the following variables: number and size of metastases, bilobar disease presence, and chemotherapy received. RESULTS: Thirty-four patients received T-ALPPS; 41 patients received TSH. After PSM, 21 patients remained in each group, with 100% resectability in the T-ALPPS group and 90.5% resectability in the TSH group. The median OS for TSH was 41 months; for T-ALPPS, the median OS was 36 months (P = 0.925). The median DFS was 16 months in the TSH group; the median DFS was 9 months in the T-ALPPS group (P = 0.930). The 1-, 3-, and 5-year OS for TSH was 81%, 66.7%, and 23.8% vs. 76.2%, 57.1%, and 22.9% for T-ALPPS, respectively. The 1-, 3-, and 5-year DFS for TSH was 66.7%, 9.5%, and 5% vs. 44.6%, 11.1%, and 11.1% for T-ALPPS, respectively. The volume increase with T-ALPPS was superior to that with TSH (68% vs. 39%; P = 0.018). There were no differences in morbidity and mortality after stages 1 and 2. CONCLUSIONS: T-ALPPS produces a similar outcome to TSH, indicating that it could be a safe and effective alternative for curative hepatectomy for all patients.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) achieves the hypertrophy of the future liver remnant in seven days. We achieved the same hypertrophy placing a tourniquet in the parenchimal transection line associating a right portal vein ligation (associating liver tourniquet and right portal vein ligation for staged hepatectomy-ALTPS). In perihiliar tumors a«non touch¼ technique should be performed. ALPPS y ALTPS do not comply with this technical aspect because a dissection of the hilum is carried out in both procedures during the portal dissection. To avoid this problem we devised a new method called sequential ALTPS. It consists of placing a tourniquet in the umbilical fissure without ligation of the right portal vein during the first stage. Subsequently, on the 4(th) postoperative day we perform a percutaneous right portal vein embolization. We present the first case of this new technique in which we have obtained a hypertrophy of 77% of the future liver remnant seven days after portal vein embolization. In the second stage a right trisectionectomy was performed with inferior vena cava resection with a goretex graft replacement.

BACKGROUND: Surgery is currently the only potentially curative treatment for hepatic or pulmonary metastases from colorectal cancer. However, the benefit of surgery and the criteria for the inclusion of patients developing hepatic and pulmonary metastases are not well defined. OBJECTIVE: The aim of this study was to describe the outcome for patients who undergo surgery for both hepatic and pulmonary metastases from colorectal cancer, to present a set of preoperative criteria for use in patient selection, and to analyze potential prognostic factors related to survival. DESIGN: This was an observational study with retrospective analysis of data collected with a prospective protocol. SETTINGS: This investigation was conducted at a tertiary centre. PATIENTS: Between January 1996 and January 2010, of 319 patients who underwent surgery for hepatic metastases from colorectal cancer, 44 also had resection of pulmonary metastases. A set of strict selection criteria established by a panel of liver surgeons, chest surgeons, oncologists, and radiologists was used. MAIN OUTCOME MEASURES: Survival was estimated with the Kaplan-Meier method, and univariate analyses were performed to evaluate potential prognostic factors for survival, including variables related to patient, primary tumour, hepatic, and pulmonary metastases and chemotherapy. RESULTS: The 44 patients received a total of 53 pulmonary resections: 36 patients had 1, 7 patients had 2, and 1 patient had 3 resections. There was no postoperative mortality and the morbidity rate after pulmonary resection was 1.8%. No patient was lost to follow-up. Overall survival was 93% at 1 year, 81% at 3 years, and 64% at 5 years. Factors related to poor prognosis in the univariate analysis were presence of more than 1 pulmonary metastasis (p = 0.04), invasion of the surgical margin (p = 0.006), and administration of neoadjuvant chemotherapy (p = 0.01 for hepatic metastases and p = 0.02 for pulmonary metastases). LIMITATIONS: The study was limited by its observational nature and the relatively small number of patients. CONCLUSION: In patients with hepatic and pulmonary metastases from colorectal cancer selected according to strict inclusion criteria, surgical treatment performed in a specialized center is a safe option that offers prolonged survival.

INTRODUCTION: After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc. AIM: To report our experience in laparoscopic liver resections (LLRs). PATIENTS AND METHOD: Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts). Twenty-eight cases received TLS and 104 had HAS. SURGICAL TECHNIQUE: 6 right hepatectomies (2 as the second stage of a two-stage liver resection); 6 left hepatectomies; 9 resections of 3 segments; 42 resections of 2 segments; 64 resections of one segment; and 5 cases of local resections. RESULTS: There was no perioperative mortality, and morbidity was 3%. With TLS the resection was completed in 23/28 cases, whereas with HAS it was completed in all 104 cases. Transfusion: 4,5%; operating time: 150min; and mean length of stay: 3,5 days. The 1-, 3- and 5-year survival rates for the primary malignant tumours were 100, 86 and 62%, and for colorectal metastases 92, 82 and 52%, respectively. CONCLUSION: LLR via both TLS and HAS in selected cases are similar to the results of open surgery (similar 5-year morbidity, mortality and survival rates) but with the advantages of minimally invasive surgery.

ALPPS (associating liver partition and portal vein ligation for staged hepatectomy), in 2-stage liver resections, achieves hypertrophy of the functional liver remnant (FLR) in 7 days, and the objective of this technique is the occlusion of the intrahepatic collaterals. In March 2012 we published a new surgical technique associating the insertion of a tourniquet in Cantlie' line and right portal vein ligation (ALTPS: Associating liver tourniquet and right portal vein occlusion for staged hepatectomy). In this paper we present this ALTPS technique placing the tourniquet in the umbilical fissure to obtain hypertrophy of segments II-III. It was performed in a 51 year-old patient with a recurrent right renal hypernephroma which involved all the anatomic right lobe and inferior vena cava. Preoperative FLR was 380 ml (20% of the total volume) increasing 150% at 7 days (to 953 ml, 31% of the total). In the second step, we performed a right trisectionectomy and retrohepatic inferior vena cava resection, replacing it by a 2 cm-ring goretex graft.
