Background and study aims

Several studies have demonstrated the superiority of proton-pump inhibitors (PPIs) in resolving erosive gastro-oesophageal reflux disease (GORD). However, this first line of treatment can fail to control symptoms in around 30% of cases, especially in the presence of non-erosive GORD. In situations where the first line of treatment fails, there is a lack of concordance regarding the best strategy to apply. This study presents a systematic review of the trials which have tested second-line treatments after PPI failure.

Methods

The study was conducted according to the PRISMA statement. The systematic review included medical trials written in English which were published between 2000 and 2016 and were retrieved from PubMed and Scopus using the keywords ‘PPI-resistant gastro-oesophageal reflux’, ‘alginate AND gastro-oesophageal reflux’, ‘hyaluronic acid AND gastro-oesophageal reflux’, ‘prokinetics AND gastro-oesophageal reflux’, ‘sucralfate AND gastro-oesophageal reflux’ and ‘baclofen AND gastro-oesophageal reflux’.

Results

Ten randomised and non-randomised studies were included, which included 1515 patients of both sexes (mean age?=?49.19?years, age range?=?18–85, males?=?700; 46.2%).

Conclusions

A personalised choice of the best treatment for PPI-resistant GORD should be based on the results of an upper endoscopy and pH/MII monitoring. For patients in situations where the first line of treatment fails, we encourage the execution of trials for testing double doses of PPIs against alternative medicaments.  相似文献

AIM: To investigate the role of laparoscopy in diagnosis and treatment of intra abdominal infections.METHODS: A systematic review of the literature was performed including studies where intra abdominal infections were treated laparoscopically.RESULTS: Early laparoscopic approaches have become the standard surgical technique for treating acute cholecystitis. The laparoscopic appendectomy has been demonstrated to be superior to open surgery in acute appendicitis. In the event of diverticulitis, laparoscopic resections have proven to be safe and effective procedures for experienced laparoscopic surgeons and may be performed without adversely affecting morbidity and mortality rates. However laparoscopic resection has not been accepted by the medical community as the primary treatment of choice. In high-risk patients, laparoscopic approach may be used for exploration or peritoneal lavage and drainage. The successful laparoscopic repair of perforated peptic ulcers for experienced surgeons, is demonstrated to be safe and effective. Regarding small bowel perforations, comparative studies contrasting open and laparoscopic surgeries have not yet been conducted. Successful laparoscopic resections addressing iatrogenic colonic perforation have been reported despite a lack of literature-based evidence supporting such procedures. In post-operative infections, laparoscopic approaches may be useful in preventing diagnostic delay and controlling the source.CONCLUSION: Laparoscopy has a good diagnostic accuracy and enables to better identify the causative pathology; laparoscopy may be recommended for the treatment of many intra-abdominal infections.  相似文献

Background

Growing evidence suggests that colorectal cancer (CRC) screening based on the fecal immunochemical test (FIT) reduces CRC incidence and surgical resection rates.

Aims

To compare trends in surgery for proximal and distal CRC among Italian regions at different stages of screening implementation.

Methods

From the National Hospital Discharge Database we selected hospitalizations with CRC resection of residents aged 50–74 years during 2002–2014, and computed surgery rates for the 8 most populous Italian regions with/without a screening program.

Results

In regions with screening, implemented around 2006–2007, the annual percent change (APC) of distal CRC resection was +1.7 (95% confidence interval ?1.0, 4.4) during 2002–2007 and ?9.1 (?10.6, ?7.7) during 2007–2014. No significant change was observed in regions without screening. The APC for proximal colon resection in regions with screening was +5.8 (2.5, 9.0) during 2002–2007 and ?4.1 (?5.8, ?2.4) during 2007–2014, while in regions without screening surgical rates increased through the whole study period. Compared to 2002, in 2014 distal CRC resection rates were greatly reduced in regions with screening, reaching values similar to proximal CRC resection.

Conclusion

Following the implementation of screening programs surgery rates steeply decreased, confirming the deep impact of FIT-based screening on the burden of CRC.  相似文献
