Long-term efficacy of total versus posterior partial fundoplication in patients with gastro-oesophageal reflux disease: a systematic review and meta-analysis.

INTRODUCTION: Laparoscopic fundoplication remains the standard treatment for patients with severe gastro-oesophageal reflux disease (GORD). Multiple randomised controlled trials (RCTs) have compared the two most commonly performed surgical techniques, total and posterior partial fundoplication (Nissen [NF] and Toupet [TF]), in terms of symptom control and treatment failure in patients without subsequent dysmotility disorders. We aimed to conduct a systematic review and meta-analysis of these two techniques with regard to the long-term effect on reflux control and associated dysphagia. METHODS: The MEDLINE®, Embase®, PubMed® and Cochrane Library databases were searched, and all the relevant published RCTs were shortlisted according to the inclusion criteria. The summated outcomes of long-term results relating to the recurrence of GORD and dysphagia were evaluated in a meta-analysis using RevMan software. RESULTS: Eight studies (all RCTs) on 1,545 patients undergoing NF or TF were eligible for inclusion in this meta-analysis. There were 799 patients in the NF group and 746 in the TF group. In the random effects model analysis, the incidence of long-term recurrence of GORD was not statistically different between the NF and TF cohorts (odds ratio [OR]: 0.69, 95% confidence interval [CI]: 0.34-1.41, z=1.01, p=0.31). However, the incidence of long-term dysphagia was statistically lower in the TF group (OR: 2.92, 95% CI: 1.49-5.72, z=3.13, p=0.002) with low between-study heterogeneity (I2=0%). CONCLUSIONS: The findings of this systematic review and meta-analysis on symptomatic GORD appear to be in favour of partial posterior fundoplication (TF) as the optimal treatment. It provides equivalent outcomes in reflux symptom control with a lower risk of postoperative dysphagia compared with total fundoplication (NF).

A diaphragmatic retroperitoneal cyst.

Diaphragmatic lesions are usually congenital bronchogenic cysts. A patient with a known diaphragmatic cyst presented with new onset right upper quadrant pain. Repeat imaging showed enlargement of the cyst, the CA19-9 cancer marker was raised at 312 iu/ml (normal: <27 iu/ml) and positron emission tomography combined with computed tomography showed focally increased uptake in the cystic wall. In view of symptoms and risk of neoplasia, the lesion was excised. Histology showed a benign epidermoid cyst. Features falsely suggesting neoplasia have been reported previously with benign splenic cysts but not with a benign diaphragmatic epidermoid cyst.
