Methods	Design: retrospective case series Aim: to determine whether a subgroup of participants with intestinal obstruction would benefit from support with PN. Patients receiving PN at home and in hospital included in study, only HPN patients included in this review. Country: Canada Funding: not reported
Participants	Number: 5 Inclusion criteria No evidence of end‐organ failure An obstructed GI tract An estimated life expectancy longer than 2 to 3 months Exclusion criteria: not reported Age: mean 44.6 years (37 to 57) Gender: 2 female and 3 male Cancer site: (n) Colon (3) Gastric (2) Patient in MBO: 100% Performance status: median Karnofsky performance status 60 (50 to 70) Treatment received: chemotherapy 3
Interventions	HPN given to all participants. No information was given about nutritional support aims or composition of PN solutions.
Outcomes	Length of survival: unclear how it was measured Adverse events: unclear how this was measured
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	High risk	No randomisation
Allocation concealment (selection bias)	High risk	No group allocation concealment
Criteria for assignment to treatments	Unclear risk	Insufficient information to permit judgement
Comparability of treatment groups	Unclear risk	Only one treatment group
Blinding of participants and personnel (performance bias) All outcomes	High risk	No blinding
Blinding of outcome assessment (detection bias) All outcomes	High risk	No blinding
Incomplete outcome data (attrition bias) All outcomes	Low risk	Length of survival: no missing data Adverse events: no missing data
Selective reporting (reporting bias)	Unclear risk	Insufficient information to permit judgement
Other bias	Low risk	The study appears to be free of other sources of bias
