Tuele Hospital

An eventful weekend and the first stoma.




Well its been a pretty full on weekend. We were going to head to Tanga for a day, but a mix up with the hospital cars meant a weekend at home. We went roaming from the house on Saturday morning, having discovered that the plot of land we look out over is actually part of the house plot! Further exploration revealed a fabulous network of ‘shamba’ – small farms that most people tend to own.

I popped into the hospital to check up on the patients from Friday. I was relieved to find that they were both in very good shape and specifically the hernia patient had suffered no apparent detriment from the mid-case excitement. Unfortunately though, he had suffered a couple of quite substantial bleeds from his wound, yesterday evening and this morning. When I first attended him, he was lying in heavily blood soaked sheets with a dressing that was soaked through. When I asked about this, I was informed that the dressing had been changed several times?!?! Unfortunately, I (nor any other surgeon) was alerted to this issue, nor was anything really done to address it! This is the other end of the spectrum from the UK when the faintest hint of ‘ongoing haemorrhage’ would generate DEFCON5, requiring immediate attendance and review (I am being a little flippant in this last statement). There was a mixture of relief and irritation when I took down the dressings to find the culprit was a feisty vessel on the skin edge (this is much better than something deep within the wound). I applied pressure for 10min and it stopped. It is disappointing that Intensive Care could not offer such intervention. Opportunities present themselves at the strangest times and this seemed like an excellent moment to teach both the nursing staff and the patient (plus relative) some simple first aid. I was very proud of my Swahili, which far from fluent, clearly communicated what I intended it to. When I returned later in the day, there had been no further trouble and the check blood count was fine (although it had dropped).

The phone rang on Saturday evening whilst I was watching a film with the chidlers (Laptops are great). I was relieved that it was not about the patient on ITU. Instead there was a patient in bowel obstruction that they wanted my review. It was almost 9pm. I quickly established that the patient had been admitted to hospital on Thursday night but had only had an X-ray taken today and had only had that reviewed this evening. The doctor I spoke to sounded excellent, and I was rather relieved to hear that although the patient was very distended, they were well and no especially concerning symptoms or signs. There are almost no staff in the hospital at night. Only a handful of nurses to cover the wards (less than one per ward), a midwife if required and a clinical officer. If other staff are needed they are called in from home. Operations such as Caesarean Sections do happen overnight, but the prospect of trying to arrange something more complicated than this was massively concerning. We agreed a plan for the night over the phone.

I reviewed the patient on Sunday morning with one of my other surgical colleagues. The clinical picture was exactly as presented to me, and I was actually incredibly impressed by the quality of the review that the patient had received. It looked like the patient had large bowel obstruction, and the X-ray strongly suggested a sigmoid volvulus to me (this is when a loop of the colon twists around on itself, a bit like a sausage balloon, causing a blockage which then gets worse until it explodes). Unfortunately, we had no equipment to try and decompress the twist endoscopically (not even a rigid sigmoidoscope) so I was left with a dilemma I would never face in the UK. Do I refer the patient to a centre that might have endoscopy equipment (but would probably just operate on the patient I am told, or possibly perforate the bowel if endoscopy was attempted) or do we proceed with the only other option available to us, a laparotomy? In no uncertain terms, I was told that a laparotomy here (done by me) would be by far the safest option (whilst a huge amount of scepticism could be held for this statement, it does correlate strongly with discussions I have had with a number of other people). We decided to go to theatre. This would take some time to organise (3hrs in the end).  Interestingly, I was also told that such an undertaking would not be safe at night. It was pushing it at the weekend, but several extra staff came in for the excitement!. Those three hours gave me quite a lot of time to mull over the predicament I found myself in. I rationalised, that whilst there were many suboptimal aspects to this case, actually for him surgery was probably not a bad option. However, I would be faced with a grossly distended colon and the intra-operative options might be less favourable than if we had managed to decompress the colon first. Furthermore, much of the kit that I would normally use in the UK was just not available. But to make matters even more tricksy, there comes the question of stomas.

Stomas are when the bowel is diverted onto the abdomen and the effluent collected in a bag. The ‘simple’ default / safe position is to perform a Hartmann’s operation, which involves chopping out the offending colon and performing a colostomy. This in theory can be reversed at a later date, but reversal is by no means an easy option (and the usual timeframe would be 3-6months at least, by which time I would be gone). Most likely it would be permanent. Furthermore, there is no such thing as stoma care here. They do know what stomas are, but long-term support for such an eventuality would be extremely limited. It would be the patient, with his relatives, with limited stoma supplies and basically no back up. I have no doubt that with the African resourcefulness they would find a way to manage, but for me making the decisions today, that was a factor I could not ignore.

As a colorectal specialist, presented with such a case in the UK we would aspire to resect the colon, and join it back up. We would ‘protect’ this join with a different temporary stoma whilst it healed (a defunctioning ileostomy with on table colon lavage). The trouble with this approach is that there are also tests (not available here) that we perform before reversing the temporary stoma to check that the colon join has healed. There are many more complexities to the decisions required today that I could elaborate further, but perhaps one last fundamental one to mention is that you want an alive patient at the end of your efforts.

It turns out we got the patient to theatre just in time. He not only had a sigmoid volvulus, but he also had a closed loop large bowel obstruction on the other side (the technical explanation for this is that he had a competent ileocaecal valve). His caecum (first part of the colon) was about to pop. If that had happened he would have died. Mortality from such an eventuality in the UK is very high and that is with super high-tech Intensive Care Units capable of supporting complex organ dysfunction. Here he would not have stood a chance. As we opened his drum like abdomen, there was much delight in theatre as the bowels bust out to greet us. Even more appreciation was shown when a simple colotomy deflated them. As a colorectal surgeon, to have such appreciation for what to me was my ‘bread and butter’ practice was a real joy. I was at home in a case like this and although I was operating in a remote part of Africa, with limited instruments, an inexperienced team and no personal professional back-up, I was surprisingly relaxed. It was tiring though.

In the end, I did a resection and primary anastomosis of the colon. I repaired the caecum and brought out a defunctioning loop ileostomy. It all looked very nice in the end, but we will have to wait and see how he recovers. I certainly did no gambling in this case, but there will always be some calculation of perceived risks. I hope that his colon heals. Equally, I have quite a lot of concern about how he will manage an ileostomy. But hopefully, I can reverse this before I leave.

A quiet and relaxing weekend then….
