Review Meta Analysis
Chewing gum and postoperative ileus in adults: a systematic literature review and meta-analysis.
Post-operative ileus (POI) is a major problem following elective abdominal surgery. Several studies have been published investigating the use of chewing gum to reduce POI. These studies however, have produced variable results. Thus, there is currently no consensus on whether chewing gum should be widely instituted as a means to help reduce POI. ⋯ Chewing gum offers only a small benefit in reducing time to flatus and time to passage of bowel motion following abdominal surgery. This benefit is of limited clinical significance. Further studies should be conducted in a modern peri-operative care environment.

Meta Analysis Comparative Study
Miniaturized extracorporeal circulation versus off-pump coronary artery bypass grafting: a meta-analysis of randomized controlled trials.
Controversies exist whether off-pump coronary artery bypass (OPCAB) is superior to miniaturized extracorporeal circulation (MECC) in reducing deleterious effects of cardiopulmonary bypass as only a number of smaller randomized controlled trials (RCT) currently provide a limited evidence base. The main purpose of conducting the present meta-analysis was to overcome the expected low power in RCTs in an attempt to establish whether MECC is comparable to OPCAB. ⋯ Using a meta-analytic approach, MECC achieves clinical results comparable to OPCAB including postoperative blood loss and blood transfusion requirement. On the basis of our findings, MECC should be considered as a valid alternative to OPCAB in order to reduce surgical morbidity of conventional cardiopulmonary bypass.

Herniorrhaphy is one of the most frequently performed general surgical operations worldwide. However, most low- and middle-income countries (LMICs) are unable to provide this essential surgery to the general public, resulting in considerable morbidity and mortality. This study aimed to estimate the prevalence, barriers to care and disability of untreated hernias in Nepal. ⋯ Despite the lower than expected prevalence of inguinal hernias, hundreds of thousands of people in Nepal are currently in need of surgical evaluation. Given that essential surgery is a necessary component in health systems, the prevalence of inguinal hernias and the cost-effectiveness of herniorrhaphy, this disease is an important target for LMICs planning surgical capacity improvements.

Developing countries without established surgical capacity face heightened morbidity and mortality from poorly understood, untreated thoracic surgical impairments. This study sought to estimate the prevalence of thoracic surgical need in a low-income country and consider contributing factors involved. ⋯ The study provides data on the prevalence of thoracic surgical conditions and factors affecting prevalence in one of the world's poorest countries. The results speak to the need for further work to enhance health systems strengthening while offering the opportunity for future training and research in resource-limited settings--an area of thoracic surgery that is not well understood.
