AIMS: The aim of this study was to assess the risk and progress of portal vein thrombosis (PVT) after splenectomy. METHODS: A prospective study was conducted in which two groups of patients were compared; each group comprised 50 patients (27 men, 23 women). Patients in the splenectomy group were of mean age 46.3 years. A second group of patients (mean age 48.5 years) had upper abdominal surgery other than splenectomy. All patients were examined before and 2 weeks after operation by duplex Doppler ultrasonography (DDUS) of the portal system. Those who developed PVT were followed up by DDUS at 6 and 12 months. RESULTS: PVT developed in 10 per cent of patients who underwent splenectomy. The portal vein was completely occluded by thrombus in 4 per cent and partially occluded in 6 per cent of patients. Symptoms and signs attributable to PVT (abdominal pain, diarrhoea, nausea, vomiting and mild fever) were found in 80 per cent of those who developed this complication. Follow-up of such patients revealed complete recanalization of portal vein in 40 per cent and partial recanalization in 60 per cent after treatment with antibiotics and long-term anticoagulation therapy. No patient who underwent upper abdominal surgery (other than splenectomy) developed PVT afterwards. CONCLUSIONS: Splenectomy (compared with other upper abdominal surgery) is followed by PVT in 10 per cent of patients but can be treated successfully.

LNF can be safely performed without the routine use of an oesophageal bougie and this practice does not result in increased post-operative dysphagia rates.

Laparoscopic repair of paraoesophageal hernias is an effective treatment with excellent short-term results and no recurrences. Our experience would suggest that an anti-reflux procedure is not always indicated and may indeed be detrimental to symptomatic outcome.
