Obesity and the Need for Bariatric Surgery in Nigeria: A Review.

Obesity was mainly regarded as a disease of developed countries, but currently there is a growing rise in the population of patients with obesity in developing countries of Africa. A body mass index of 30 kg/m2 or higher is regarded as obesity, and this may be associated with comorbidities such as metabolic and cardiovascular diseases, orthopaedic and psychiatric conditions, and cancer. There is conclusive scientific evidence that shows that obesity is caused by complex psychosocial, genetic and environmental factors.

Stenting the Upper/Cervical Oesophagus with a Proximal Deployment Cervical Oesophageal Stent: Technique and Outcomes.

Introduction: Proximal oesophageal stent deployment continues to provide challenges due to the proximity of the upper oesophageal sphincter and the associated subsequent complications such as globus sensation and stent migration. Patients with cervical oesophageal cancer have previously had limited stenting options available to them with a paucity of the literature describing the radiological technique for successfully placing these high-risk stents. In this paper, we present our experience using the Taewoong Niti-S CERVICAL Oesophageal Stent.

Patients' reaction to the ethical conduct of radiographers and staff services as predictors of radiological experience satisfaction: a cross-sectional study.

Background: Patients' satisfaction arises from their appraisal of experience in hospital services and measuring patients' satisfaction in hospital has become a global phenomenon. To improve on patients' satisfaction, radiographers have to imbibe the right ethical attitude in their conduct while discharging duties to patients during radiological examination. The objective of this study is to understand from the patients' perspective the ethical conduct of radiographers and radiology nurses that constitute factors in patient satisfaction during routine radiological examination.

Billroth 1 versus Roux-en-Y reconstructions: a quality-of-life survey at 5 years.

Background: In the majority of gastric surgical units across Japan, Billroth 1 is the preferred method of anastomosis following subtotal distal gastrectomy for gastric cancer. However, across Europe and North America, reconstruction using a Roux-en-Y anastomosis is more common. There is a lack of comparative studies of the two methods focusing on long-term outcome.

Curative resection for low rectal adenocarcinoma: abdomino-perineal vs anterior resection.

Objective: Local recurrence after abdomino-perineal excision of the rectum for tumours has been reported to occur in up to a third of patients in contrast to 4% after restorative anterior resection.

Method: Low rectal tumours were defined as tumours within 8 cm of the anal verge and were treated by either stapled low anterior resection (SLAR) or abdomino-perineal excision of the rectum (APER). One hundred and seventy-eight patients with tumours in the lower third of the rectum (30% of 591 rectal cancers) underwent surgical resection between 1980 and 2001.
