Brief summary
Recently a new method of induce similar hypertrophy in the liver as is observed after hepatectomy has been described and was given the eponym ALLPS. ALPPS stands for Associating Liver Partition with Portal Vein Ligation for Staged Hepatectomy (ALPPS). Since the procedure is used worldwide this international registry was created to enable tracking of cases performed worldwide for safety and outcomes and innovations by the groups involved as well as allows a non-randomized comparison to the conventional methods of portal vein occlusion.
Detailed description
The ALPPS registry is accessible online through the data portal www.allps.net. Registered members recieve access through a member ID and password. Data submission is supported by the SECUTRIAL software, supported by the Clinical Trials center of the University of Zurich. All data submitted are anonymized before entry through the SECUTRIAL Software. Administration of the registry data is performed through the Department of Visceral and Transplantation Surgery in the University Hospital Zurich and the Clinical Trials Center of the University of Zurich, Switzerland, in collaboration with the Italian Hospital in Buenoas Aires, Argentina. A Scientific Committee has been appointed to give approval for any data analysis. Any participating center may apply for data analysis. Particiating International Centers have responsibility for the validity of the data submitted and the respective local institutional review procedures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Morbidity and mortality (peripoerative) | 3 months | Primary outcome variablesis perioperative mortality and complications and survival status after 3 months. Data will be entered following the widely accepted Clavien-Dindo classification system . |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Long term survival | 5 years | Outcome variables include long term survival after 3, 6, 12, 18 and 24 month, survival status after 3, 4, and 5 years. If the patient is still alive the data about hepatic recurrence and systemic recurrence will be collected. If there is a recurrence the type of treatment will be recorded. |
| Perioperative liver and renal function | 5 days | Outcome variables include liver and renal function after surgery. INR and Total bilirubin as well as creatinine prior to surgery and 5 days after stage 1 and five days after stage 2 are recorded and commonly accepted citeria for postoperative liver and postoperative renal failure are used to assess these 2 types of complications. |
| Disease specific recurrence/failure to cure | 5 years | Outcome variables include disease specific failure to cure (to completely resect) or disease specific recurrence after 3, 6, 12, 18 and 24 month, survival status after 3, 4, and 5 years. If there is a failure to cure or recurrence, the type of treatment will be recorded. |
| Liver Growth as assessed by imaging-based volumetry | between stage 1 and stage 2 (1-12 weeks) | Outcomes variables include Liver Growth as assessed by imaging-based volumetry between stage 1 and stage 2 (1-12 weeks)as assessed either by computer tomography or magnetic resonance based volumetry |
Other
| Measure | Time frame | Description |
|---|---|---|
| Inclusion criteria by registry participants | at enrollment | The registry will evaluate the criteria used by study participants to include patients to the ALPPS procedure including tumor type, size, number extent, liver parechymal quality, starting volumes, resection volumes and specific methods of resection or sequneces of methods of resection used. |
