Five-year Comorbidity Outcomes in Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB): A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Laparoscopic vertical sleeve gastrectomy (LVSG) is now the most commonly performed bariatric procedure; however, it remains to be elucidated if it delivers equivalent long-term comorbid disease resolution outcomes similar to the longer established laparoscopic Roux-en-Y gastric bypass (LRYGB). We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the comparative 5-year outcomes of both procedures.

Methods: Electronic databases (Pubmed, EMBASE, CINAHL) were searched for RCTs conducted in adults (>18y) that compared the 5-year- outcomes of LVSG to LRYGB and described comorbidity outcomes were included.

Prophylactic Onlay Mesh Repair (POMR) Versus Primary Suture Repair (PSR) for Prevention of Incisional Hernia (IH) After Abdominal Wall Surgery: A Systematic Review and Meta-analysis.

Background: With many different operative techniques in use to reduce the incidence of incisional hernias (IH) following a midline laparotomy, there is no consensus among the clinicians on the efficacy and safety of any particular repair technique. This meta-analysis compares the prophylactic onlay mesh repair (POMR) and primary suture repair (PSR) for the incidence of IH.

Methods: A meta-analysis and systematic review of MEDLINE, PubMed Central (via PubMed), Embase (via Ovid), SCOPUS, ScienceDirect, Google Scholar, SCI and Cochrane Library databases were undertaken.

Bariatric surgery and gastroesophageal reflux disease.

With the rapidly increasing prevalence of obesity globally, the practice of bariatric surgery is being adopted routinely to prevent the development of chronic conditions as well as some forms of cancers associated with obesity. Gastroesophageal reflux disease (GERD) is one of those chronic conditions. Furthermore, there is accumulating data that obesity is associated with complications related to longstanding GERD such as erosive esophagitis (EE), Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC).

Micronutrient management following bariatric surgery: the role of the dietitian in the postoperative period.

Bariatric surgery is increasingly being utilized to manage obesity and obesity related comorbidities, but may lead to the development of micronutrient deficiencies postoperatively. The anatomical, physiological, nutritional and behavioral reasons for micronutrient vulnerabilities are reviewed, along with recommendations for routine monitoring and replacement following surgery. The role the dietitian and their contribution in the postoperative identification, prevention and management of micronutrient vulnerabilities in bariatric patients is described.

Pharmaconutrition administration on outcomes of elective oncological surgery for gastrointestinal malignancies: is timing everything?-a review of published meta-analyses until the end of 2016.

The last 25 years have seen an increasing number of publications attesting the benefits of pharmaconutrition in the management of patients undergoing elective oncological gastrointestinal surgery. A number of randomized controlled trials and meta-analyses suggest the use of pharmaconutrition in this group of patients produces superior outcomes to standard nutritional formulations in terms of postoperative infective complications, anastomotic breakdown and length of hospital stay. The use of pharmaconutrition products, therefore, has gained increasing acceptance for use in elective gastrointestinal oncological surgical populations and been incorporated into practice guidelines.

Management of oesophageal intramucosal carcinoma.

We present an interesting case of an intramucosal carcinoma (IMC) in the setting of Barrett's oesophagus in a 66-year-old woman. Her clinical course highlights the shifting paradigm in the approach to management of Barrett's oesophagus and IMC. With innovation in imaging and endoscopic treatment modalities, patients are detected earlier and managed prior to development of malignancy.

Causes of recurrence in laparoscopic inguinal hernia repair.

Purpose: Recurrence after laparoscopic inguinal herniorrhaphy is poorly understood. Reports suggest that up to 13% of all inguinal herniorrhaphies worldwide, irrespective of the approach, are repaired for recurrence. We aim to review the risk factors responsible for these recurrences in laparoscopic mesh techniques.

Meta-analysis of histopathological outcomes of laparoscopic assisted rectal resection (LARR) vs open rectal resection (ORR) for carcinoma.

Background: We conducted a meta-analysis of the randomized evidence to determine the relative merits of histopathological outcomes of laparoscopic assisted (LARR) versus open rectal resection (ORR) for rectal cancer.

Data Sources: A search of PubMed and other electronic databases comparing LARR and ORR between Jan 2000 and June 2016 was performed. Histopathological variables analyzed included; location of rectal tumors; complete and incomplete TME; positive and negative circumferential resection margins (+/-CRM); positive distal resected margins (+DRM); distance of tumor from DRM; number of lymph nodes harvested; resected specimen length; tumor size and perforated rectum.

Changes in Non-Diabetic Comorbid Disease Status Following Laparoscopic Vertical Sleeve Gastrectomy (LVSG) Versus Laparoscopic Roux-En-Y Gastric Bypass (LRYGB) Procedures: a Systematic Review of Randomized Controlled Trials.

Purpose: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this systematic review was to study the peer review literature regarding postoperative nondiabetic comorbid disease resolution or improvement reported from randomized controlled trials (RCTs) comparing LVSG and LRYGB procedures.

Material And Methods: RCTs comparing postoperative comorbid disease resolution such as hypertension, dyslipidemia, obstructive sleep apnea, joint and musculoskeletal conditions, gastroesophageal reflux disease, and menstrual irregularities following LVSG and LRYGB were included for analysis.

Diabetes improvement and resolution following laparoscopic vertical sleeve gastrectomy (LVSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures: a systematic review of randomized controlled trials.

Background: The prevalence of type 2 diabetes is growing in both developed and developing countries and is strongly linked with the prevalence of obesity. Bariatric surgical procedures such as laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are increasingly being utilized to manage related comorbid chronic conditions, including type 2 diabetes.

Methods: A systematic review of randomized controlled trials (RCTs) was undertaken using the PRISMA guidelines to investigate the postoperative impact on diabetes resolution following LVSG versus LRYGB.

Laparoscopic anterior versus posterior fundoplication for gastro-esophageal reflux disease: a meta-analysis and systematic review.

Objectives: Although laparoscopic posterior fundoplication (LPF) i.e., Nissen or Toupet have the proven efficacy for controlling gastro-esophageal reflux surgically, there remain problems with postoperative dysphagia and gas bloat syndrome.

Effect of timing of pharmaconutrition (immunonutrition) administration on outcomes of elective surgery for gastrointestinal malignancies: a systematic review and meta-analysis.

Background: Pharmaconutrition has previously been reported in elective surgery to reduce postoperative infective complications and duration of hospital length of stay.

Objective: To update previously published meta-analyses and elucidate potential benefits of providing arginine-dominant pharmaconutrition in surgical patients specifically with regard to the timing of administration of pharmaconutrition.

Design: Randomized controlled trials comparing the use of pharmaconutrition with standard nutrition in elective adult surgical patients between 1980 and 2011 were identified.

Are we jumping the gun with pharmaconutrition (immunonutrition) in gastrointestinal onoclogical surgery?

Over the last 20 years there has been considerable research into the use of immunonutrition, also referred to as pharmaconutrition, in the management of patients undergoing and recovering from elective gastrointestinal surgery for malignancy. In this group of patients, the use of pharmaconutrition seems to confer superior outcomes to standard nutrition formulations with regards to postoperative infective complications and length of hospital stay. It is therefore frequently recommended for use in elective gastrointestinal oncological surgical populations.
