RESUMO
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: Despite the minimally invasive approach and early rehabilitation, abdominal-perineal resection (APR) remains a procedure with high morbidity, notably due to postoperative trapped bowel ileus and perineal healing complications. Several surgical techniques have been described for filling the pelvic void to prevent abscess formation and ileus by trapped bowel loop. OBJECTIVE: The aim of our study was to compare the post APR complications for cancer of two of these techniques, omentoplasty and cecal mobilization, in a single-center study from an expert colorectal surgery center. PATIENTS: From 2012 to 2022, 84 patients were included, including 58 (69%) with omentoplasty and 26 (31%) with cecal mobilization. They all underwent APR at Bordeaux University Hospital Center. SETTINGS: A propensity score was used to avoid confounding factors as far as possible. Patient and procedure characteristics were initially comparable. RESULTS: The 30-day complication rate was significantly higher in the cecal mobilization group (53.8% vs. 5.2% p < 0.01), as was the rate of pelvic abscess (34.6% vs. 0% p < 0.001). CONCLUSION: These findings suggest that, when feasible, omentoplasty should be considered the preferred method for pelvic reconstruction following APR.

INTRODUCTION: Low-pressure pneumoperitoneum (LLP) in laparoscopy colorectal surgery (CS) has resulted in reduced hospital stay and lower analgesic consumption. Microsurgery (MS) in CS is a technique that has a significant impact with respect to postoperative pain. The combination of MS plus LLP, known as low-impact laparoscopy (LIL), has never been applied in CS. Therefore, this trial will assess the efficacy of LLP plus MS versus LLP alone in terms of decreasing postoperative pain 24 h after surgery, without taking opioids. METHOD: PAROS II will be a prospective, multicentre, outcome assessor-blinded, randomised controlled phase III clinical trial that compares LLP plus MS versus LLP alone in patients undergoing laparoscopic surgery for colonic or upper rectal cancer or benign pathology. The primary outcome will be the number of patients with postoperative pain 24 h after the surgery, as defined by a visual analogue scale rating ≤3 and without taking opioids. Overall, PAROS II aims to recruit 148 patients for 50% of patients to reach the primary outcome in the LLP plus MS arm, with 80% power and an 5% alpha risk. CONCLUSION: The PAROS II trial will be the first phase III trial to investigate the impact of LIL, including LLP plus MS, in laparoscopic CS. The results may improve the postoperative recovery experience and decrease opioid consumption after laparoscopic CS.

INTRODUCTION: Protective diverting ileostomy is commonly performed in rectal surgery to avoid septic complications of low colorectal anastomosis. Ileostomy closure usually occurs three months after the surgery and can be realized in two ways: hand sewn or stapled. Existing randomized studies comparing the two techniques showed no difference in terms of complications. METHODS: Our study describes the standard technique of ileostomy reversal as done in Bordeaux University Hospital in 10 steps individually illustrated and with an explicative video. We also collected data concerning the 50 last patients who underwent an ileostomy reversal in our center from June 2021 to June 2022. RESULTS: Mean duration of the ileostomy closure was 46.8 minutes, and the mean total hospital stay was 4.66 days. Five of 50 (10%) patients had a post-operative bowel obstruction, 2/50 (4%) patients had a post-operative bleeding, 1/50 (2%) patient had a wound infection, and there was no anastomotic leakage observed. CONCLUSION: Stapled side-to-side anastomosis is a rapid, simple, and reproducible technique for ileostomy reversal. There are no more complications compared to hand-sewn anastomosis. It engenders an additional cost compensated by the gain in operating time which altogether saves money.

BACKGROUND: Hepaticojejunostomy (HJ) is the gold standard procedure for repairing major bile duct injury (BDI). Dilation status of the BD before repair has not been assessed as a risk factor for anastomotic stricture. METHOD: This retrospective single-centre study was performed on a population of 87 patients with BDI repaired by HJ between 2007 and 2021. Dilation status was assessed preoperatively, and dilation was defined as the presence of visible peripheral intrahepatic BDs with remaining BD diameter > 8 mm. The short- and long-term outcomes of HJ were assessed according to preoperative dilation status. RESULTS: Before final repair, the BDs were dilated (dBD) in 56.3% of patients and not dilated (ND) in 43.7%. Patients with ND at the time of repair had more severe BDI injury than those with dBD (94.7% vs. 77.6%, p = 0.026). The rate of preoperative cholangitis was lower in patients with ND than in those with dBD (10.5% vs. 44.9%, p = 0.001). The rate of short-term morbidity after HJ was 33.3% (ND vs. dBD: 38.8% vs. 26.3%, p = 0.32). Long-term anastomotic stricture rate was 5.7% with a mean follow-up period of 61.3 months. There were no differences in long-term biliary complications according to dilation status (ND vs. dBD: 12.2% vs. 10.5%, p = 1). CONCLUSION: Dilation status of the BD before HJ for BDI seemed to have no impact on short- or long-term outcomes. Both surgical and radiological external biliary drainages after BDI appear to be acceptable options to reduce cholangitis before repair without increasing risk for long-term anastomotic stricture.

PURPOSE: A transjugular intrahepatic portosystemic shunt (TIPS) before the liver transplantation (LT) has been considered a contraindication in cases of hepatocellular carcinoma (HCC) because of the risk of tumour growth. We aimed to assess the impact of TIPS on incidental HCC and oncological outcomes in transplanted patients with pre-existing HCC. METHODS: All consecutive transplanted patients for cirrhosis who had a previous TIPS with or without HCC were included. Between 2007 and 2014, 1912 patients were transplanted. We included 122 (6.3%) patients having TIPS before LT. A 1:3 matched cohort of 366 patients (18.9%) having LT without previous TIPS was selected using a propensity score. Incidental HCC rate and risk factor of HCC recurrence were evaluated using multivariate analysis with a competing risk model. RESULTS: Before LT, in the TIPS group, 27 (22.1%) had an HCC vs. 81 (22.1%) in the control group (p = 1). The incidental HCC rate was similar: 10.5% (10/95) in the TIPS group vs. 6.3% (18/285) in the control group (p = 0.17). Recurrence occurred in 1/27 (3.7%) patient in the TIPS group and in 7/81 (8.6%) patients in the control group, without significant difference (p = 0.51). After multivariate regression, patient's gender (p < 0.01) was significantly associated with HCC recurrence while a tumour within Milan criteria (p = 0.01, sHR: 0.17 [0.04; 0.7]) and an incidental HCC (p<0.01) were found to be protector factors against HCC recurrence. CONCLUSION: TIPS did not worsen the prognosis of transplanted patients for HCC. TIPS should no longer be contraindicated for oncological reasons in patients with HCC waiting for an LT.

BACKGROUND: High-risk pancreatic anastomosis can lead to a high mortality rate after PD due to the development of postoperative pancreatic fistula (POPF). Performing a wirsungostomy by externalizing the pancreatic duct is a poorly known alternative to anastomosis which could reduce the risk of POPF and the associated severe morbidity METHODS: We retrospectively evaluated patients who underwent primary wirsungostomy with PD from January 2007 to December 2021 in our tertiary referral center. Rates of morbidity and mortality with long-term pancreatic functions were studied. RESULTS: Sixty patients were included. The median Updated Alternative Fistula Risk Score (ua-FRS) was 52%, with 95% patients in the high-risk ua-FRS category and 88.3% patients with stage D risk of developing POPF according to the classification of the ISGPS. The mortality rate was 3.3%, and overall 90-day postoperative morbidity was 63.7% with 50% of patients developing major complications. Mean follow-up was 29.8 months. Twelve patients (20%) became diabetic and 35 patients (58.3%) had preserved pancreatic endocrine function CONCLUSION: Preemptive wirsungostomy with PD could be an appropriate procedure for patients with high-risk pancreatic anastomosis. The high associated morbidity could be compromised by the low mortality and preservation of endocrine function compared to total pancreatectomy or severe POPF.

OBJECTIVE: The objective of this retrospective single centre study was to determine whether different enteric reconstruction methods and adjuncts confer a benefit after in situ reconstructions (ISRs) of graft aorto-enteric erosion (AEnE) and fistula (AEnF). METHODS: Primary endpoints were in hospital mortality and AEnE/F recurrence. Survival was estimated using the Kaplan-Meier method and explanatory factors were searched for using uni- ± multivariable Cox regression analysis. In 2013, a multidisciplinary team meeting was convened and since then the primary operator has always been a senior surgeon. RESULTS: Sixty-six patients were treated for AEnE (n = 38) and AEnF (n = 28, 42%) from 2004 to 2020. All patients with AEnF presented with gastrointestinal bleeding (vs. 0 for AEnE; p < .001). Signs of infection were seen in 50 patients (76% [37 for AEnE vs. 13 for AEnF]; p < .001). Referrals for endograft infection increased over time (n = 15, 23%; one before 2013 vs. 14 after; p = .002). Most patients underwent complete graft excision (n = 52, 79%) with increasing suprarenal cross clamping (n = 21, 32%; four before 2013 vs. 17 after; p = .015). Complex visceral reconstructions decreased over time (n = 31, 47%; 17 before 2013 vs. 14 after; p = .055), while "open abdomens" (OAs) increased (one before 2013 vs. 22 after; p < .001), reducing operating time (p = .012). In hospital mortality reached 42% (n = 28). Estimated survival reached 47.6% (95% confidence interval [CI] 35.0 - 59.1) at one year and 45.6% (95% CI 33.0 - 57.3) at three years and was higher for AEnE than for AEnF (log rank p = .029). AEnE/F recurrence was noted in 12 patients (18%). Older age predicted in hospital mortality in multivariable analysis (p = .034). AEnE/F recurrence decreased with the presence of a primary senior surgeon (vs. junior; p = .003) and OA (1 [4.4%] vs. 11 [26%] for primary fascial closure; p = .045) in univariable analysis. CONCLUSION: Mortality and recurrence rates remain high after ISR of AEnE/F. Older age predicted in hospital mortality. Primary closure of enteric defects ≤ 2 cm in diameter reduced operating time without increasing the recurrence of AEnF.

BACKGROUND: Sacrificing a replaced right hepatic artery (rRHA) from the superior mesenteric artery is occasionally necessary to obtain an R0 resection after pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PA). Preoperative embolization (PEA) of the rRHA has been proposed to avoid the onset of postoperative biliary and ischemic liver complications. METHODS: Eighteen patients with cephalic PA with an rRHA underwent PEA of the rRHA from 2013 to 2019. The monitoring after embolization and PD was systematic and included a clinical-biological evaluation and a computed tomography scan. This study aimed to determine the feasibility of PEA of the rRHA, postoperative morbidity at 90 days, and quality of oncologic resection after PD. RESULTS: Feasibility of PEA was 100% without complications. A PD was performed in 16/18 patients. Mortality was 2/16 with one death after septic shock with hepatic ischemia without an arterial obstruction. Overall morbidity was 44% including one hepatic abscess after hepatic ischemia (6%). Two resections were R1 (<1 mm) in contact with the origin of the rRHA (2/4 R1). CONCLUSION: PEA of the rRHA before PD was safe and reproducible. PEA of the rRHA followed by en bloc PD resection seems to limit the risk of bilio-hepatic ischemia and could facilitate oncologic resection.

OBJECTIVE: The aim of this retrospective study was to compare portal vein embolization (PVE) and radiologica simultaneous portohepatic vein embolization (RASPE) for future liver remnant (FLR) growth in terms of feasibility, safety, and efficacy. SUMMARY OF BACKGROUND DATA: After portal vein embolization (PVE), 15% of patients remain ineligible for hepatic resection due to insufficient hypertrophy of the FLR. RASPE has been proposed to induce FLR growth. MATERIALS AND METHODS: Between 2016 and 2018, 73 patients were included in the study. RASPE was proposed for patients with a ratio of FLR to total liver volume (FLR/TLV) of <25% (RASPE group). This group was compared to patients who underwent PVE for a FLR/TLV <30% (PVE group). Patients in the 2 groups were matched for age, sex, type of tumor, and number of chemotherapy treatments. FLR was assessed by computed tomography before and 4 weeks after the procedure. RESULTS: The technical success rate in both groups was 100%. Morbidity post-embolization, and the time between embolization and surgery were similar between the groups. In the PVE group, the FLR/TLV ratio before embolization was 31.03% (range: 18.33%-38.95%) versus 22.91% (range: 16.55-32.15) in the RASPE group (P < 0.0001). Four weeks after the procedure, the liver volume increased by 28.98% (range: 9.31%-61.23%) in the PVE group and by 61.18% (range: 23.18%-201.56%) in the RASPE group (P < 0.0001). Seven patients in the PVE group, but none in the RASPE group, had postoperative liver failure (P = 0.012). CONCLUSIONS: RASPE can be considered as "radiological associating liver partition and portal vein ligation for staged hepatectomy." RASPE induced safe and profound growth of the FLR and was more efficient than PVE. RASPE also allowed for extended hepatectomy with less risk of post-operative liver failure.

BACKGROUND: Clear-cell renal cell carcinoma frequently metastasizes to the pancreas (PMRCC). The management of such metastases remains controversial due to their frequent multifocality and indolent evolution. METHODS: This study describes the surgical management of these lesions and their long-term oncological outcomes. The study included patients who underwent pancreatic resection of PMRCC at Bordeaux University Hospital between June 2005 and March 2022. Morbidity and mortality were assessed at 90 days. Overall survival (OS) and disease-free (DFS) survival were assessed at 5 years. RESULTS: Forty-two patients underwent pancreatic resection for PMRCC, including 18 (42.8 %) total pancreatectomies. The median time from nephrectomy to the diagnosis of PMRCC was 121 (range: 6-400) months. Lesions were multiple in 19/42 (45.2 %) patients. Ten (23.8 %) patients suffered a severe complication (Dindo-Clavien classification ≥ IIIA by D90), including one patient who died postoperatively. The median follow-up was 76 months. The R0 rate was 100 %. The OS and DFS rates were 92.8 % and 29.6 %, respectively, at 5 years. CONCLUSION: Pancreatic resection for PMRCC provides long-term oncological control despite a high recurrence rate.

The aim of this didactical video is to show an easy and standardized technique of liver preparation after "en bloc" extraction and access a young surgeon to perform liver procurement. The technique entails five steps: beginning with the dissection of the vena cava, the superior mesenteric artery, and the coeliac trunk, followed by the common hepatic artery, the bile duct and finally the portal vein. This technique of liver graft preparation has high reproducibility while maintaining the safety of the procedure for young surgeons. The "en bloc" extraction with a standardized liver graft preparation is an easy and a reproducible technique.
