Relative's experience - two surgeries, years apart, for two sites of stricture at each surgery.
Go into hospital, relatively straight forward op but took a few hours both times, long-ish abdominal scar (I think because of the multiple sites, first scar was re-used in second surgery).
1 week in hospital post-op, epidural for the op followed by IV pain relief for about a day or two, after which moved onto morphine pills (combination of slow release and quick release). Weaned off slowly through GP after discharge.
6 week initial at-home recovery: daily nurse visits to change bandages and check stitches until healed enough to maintain personally, final visit to local clinic to check all was well and discharge from regional nursing team. Weaned off of the morphine during this time.
6 month overall initial recovery: much better after 1-2 months but still have to be cautious, no carrying heavy items or over exertion, tired out more easily than pre-op, weaker overall, walking shorter distances etc.
6 months to 18 months post-op: continuation of regaining strength, getting back to normal, surgery can really take it out of you as the abdominal muscles play a part in a lot of what you do. But generally all okay by this point.
This isn't trying to say that it takes 6 months just to start feeling 'okay', this is the outline given by the gastro team at the hospital and relative followed this trend pretty much. I would say that by 2 months post-op things were much better and much closer to 'normal', but there is a longer period of recovery for regaining full strength and physical capability.
Suffice to say however the op had a very positive impact and felt much better and glad to have had it done! Within 6 weeks of the op was happily out and about enjoying a birthday meal in a nice restaurant without constipation/vomiting/passing out...
Best of luck with it
