I had an episode of acute cholecystitis that resulted in hospital treatment / admission. On discharge the treatment plan was to return the next day to be scanned and confirm the diagnosis. Once confirmed then I would be referred for removal which would be done within 2 months. But none of that happened. I had the scan nearly a week later and did confirm the gallstones but the surgical referral didn't happen. I was treated in a hospital where I was working at the time and asked for all the follow up to be done via them but of course when I rang to chase the referral I was told everything had been passed to my home trust. Visits to my GP then followed - getting information that had been 'passed to them' took weeks.
At several appointments I was told different things - you need to have 1/2/3/4/5+ more attacks before surgery would be considered, we need to repeat the scan, you don't need your gallbladder removed at all etc. I gave up!
Suffered 2 more mild attacks needing a visit to a walk in and painkiller prescription. Then 9 months later suffered a humdinger of an attack. Another hospital admission. Needed 2 weeks off work - combination of the attack and horrible side effects from every pain relief I was prescribed. Further GP visits throughout these 2 weeks elicited the response 'well, if you insist I'll do the surgical referral but they won't remove it'. Eventually I did insist.
Surgeon recommended referral - but only after I pointed out that I had had 2 severe and 2 milder attacks, only the last attack had been mentioned in the actual referral grrrr. Wait time was 3 months.
So nearly 12 months since the first attack where surgery within 2 months was recommended I had my Gallbladder removed. Meanwhile having stuck to the 'eat no fat' diet quite well my Type 2 Diabetes had spiraled out of control as I was no longer able to diet control it (Low Carb, Higher Fat) so I was now on medication for that!
I was looking at private treatment as the time off work I was having was beginning to have an impact (1 week, 2 days, 2 days, 2 weeks). Cost was around £6,000 - £8,000.
I don't know what to advise you as obviously I didn't get the treatment (gallbladder removal) needed and recommended. Those 12 months spent knowing another attack could happen severely impacted my life outside work too, I walk the mountains (alone) as my hobby but knew that if I had a severe attack I would not be able to self evacuate so stopped doing that unless someone was with me and even then restricted where I went / how long for / how far away from 'civilization'.
The two trusts batting my case between themselves ended up costing them both so much more financially and me the stress of waiting for the next attack.
Sorry for the long post
There might be something in there useful to you.
