ALPPS Procedure for Extended Liver Resections: A Single Centre Experience and a Systematic Review.

ABSTRACT:

Aim

To report a single-centre experience with the novel Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) technique and systematically review the related literature.

Methods

Since January 2013, patients with extended primary or secondary liver tumors whose future liver remnant (FLR) was considered too small to allow hepatic resection were prospectively assessed for the ALPPS procedure. A systematic literature search was performed using PubMed, Scopus and the Cochrane Library Central.

Results

Until July 2014 ALPPS was completed in 9 patients whose mean age was 60 ± 8 years. Indications for surgical resection were metastases from colorectal cancer in 3 cases, perihilar cholangiocarcinoma in 3 cases, intrahepatic cholangiocarcinoma in 2 cases and hepatocellular carcinoma without chronic liver disease in 1 case. The calculated FLR volume was 289 ± 122 mL (21.1 ± 5.5%) before ALPPS-1 and 528 ± 121 mL (32.2 ± 5.7%) before ALLPS-2 (p < 0.001). The increase in FLR between the two procedures was 96 ± 47% (range: 24-160%, p < 0.001). Additional interventions were performed in 4 cases: 3 patients underwent Roux-en-Y hepaticojejunostomy, and one case underwent wedge resection of a residual tumor in the FLR. The average time between the first and second step of the procedure was 10.8 ± 2.9 days. The average hospital stay was 24.1 ± 13.3 days. There was 1 postoperative death due to hepatic failure in the oldest patient of this series who had a perihilar cholangiocarcinoma and concomitant liver fibrosis; 11 complications occurred in 6 patients, 4 of whom had grade III or above disease. After a mean follow-up of 17.1 ± 8.5 months, the overall survival was 89% at 3-6 and 12 months. The recurrence-free survival was 100%, 87.5% and 75% at 3-6-12 months respectively. The literature search yielded 148 articles, of which 22 articles published between 2012 and 2015 were included in this systematic review.

Conclusion

The ALPPS technique effectively increased the resectability of otherwise inoperable liver tumors. The postoperative morbidity in our series was high in accordance with the data from the systematic review. Age, liver fibrosis and presence of biliary stenting were predisposing factors for postoperative morbidity and mortality.

Project description:To compare the outcomes of modified-Associating Liver Partition and Portal vein Ligation for Staged hepatectomy (ALPPS) techniques with those of conventional-ALPPS.BackgroundALPPS is an established technique for treating advanced liver tumors.MethodsPubMed, Web of Science, and Cochrane databases were searched. The outcomes were assessed by single-arm and 2-arm analyses.ResultsSeventeen studies containing 335 modified-ALPPS patients were included in single-arm meta-analysis. The estimated blood loss was 267 ± 29 mL (95% confidence interval [CI], 210-324 mL) during the first and 662 ± 51 mL (95% CI, 562-762 mL) during the second stage. The operation time was 166 ± 18 minutes (95% CI, 131-202 minutes) during the first and 225 ± 19 minutes (95% CI, 188-263 minutes) during the second stage. The major morbidity rate was 14% (95% CI, 9%-22%) after the first stage. The future liver remnant hypertrophy rate was 65.2% ± 5% (95% CI, 55%-75%) and the interstage interval was 16 ± 1 days (95% CI, 14-17 days). The dropout rate was 9% (95% CI, 5%-15%). The overall complication rate was 46% (95% CI, 37%-56%) and the major complication rate was 20% (95% CI, 14%-26%). The postoperative mortality rate was 7% (95% CI, 4%-11%). Seven studies containing 215 patients were included in comparative analysis. The hypertrophy rate was not different between 2 methods (mean difference [MD], -5.01; 95% CI, -19.16 to 9.14; P = 0.49). The interstage interval was shorter for partial-ALPPS (MD, 9.43; 95% CI, 3.29-15.58; P = 0.003). The overall complication rate (odds ratio [OR], 10.10; 95% CI, 2.11-48.35; P = 0.004) and mortality rate (OR, 3.74; 95% CI, 1.36-10.26; P = 0.01) were higher in the conventional-ALPPS.ConclusionsThe hypertrophy rate in partial-ALPPS was similar to conventional-ALPPS. This shows that minimizing the first stage of the operation does not affect hypertrophy. Moreover, the postoperative overall morbidity and mortality rates were lower following partial-ALPPS.

Project description:Ketogenic diet therapies (KDT) are high-fat, low carbohydrate diets used as an effective treatment option for drug-resistant epilepsy. There is limited research on the efficacy of KDT for super-refractory status epilepticus (SRSE). We systematically review evidence for use of KDT in children with SRSE and present a single UK tertiary centre's experience. Thirty one articles were included, of which 24 were "medium" or "low" quality. One hundred and forty seven children with SRSE started KDT, of which 141 (96%) achieved ketosis. KDT was started mean 5.3 days (range 1-420) after status epilepticus (SE) started. SRSE resolved in 85/141 (60%) children after mean 6.3 days (range 0-19) post SE onset, but it is unclear whether further treatments were initiated post-KDT. 13/141 (9%) children died. Response to KDT was more likely when initiated earlier (p = 0.03) and in females (p = 0.01). Adverse side effects were reported in 48/141 (34%), mostly gastrointestinal; potentially serious adverse effects occurred in ≤4%. Eight children with SRSE, all diagnosed with febrile infection-related epilepsy syndrome, were treated with KDT at Great Ormond Street Hospital for Children. KDT was initiated enterally at mean day 13.6+/- 5.1 of admission. Seven of 8 (88%) children reported adverse side effects, which were potentially serious in 4/8 (50%), including metabolic acidosis, hypoglycaemia and raised amylase. SE ceased in 6/8 (75%) children after mean 25+/- 9.4 days post onset, but other treatments were often started concomitantly and all children started other treatments post-KDT. Two of 8 (25%) children died during admission and another died post-admission. Four of the remaining 5 children continue to have drug-resistant seizures, one of whom remains on KDT; seizure burden was unknown for one child. Our findings indicate that KDT is possible and safe in children with SRSE. Cessation of SRSE may occur in almost two-thirds of children initiated with KDT, but a causal effect is difficult to determine due to concomitant treatments, treatments started post-KDT and the variable length of time post-KDT onset when SRSE cessation occurs. Given that serious adverse side effects seem rare and response rates are (cautiously) favorable, KDT should be considered as an early treatment option in this group.
