MATERIAL AND METHODS: RCTs comparing the weight loss outcomes following LVSG and LRYGB in adult population between January 2000 and November 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The review was prepared in accordance with Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA).
RESULTS: Nine unique RCTs described over 10 publications involving a total of 865 patients (LVSG, n=437; LRYGB, n=428) were analyzed. Postoperative follow-up ranged from 3 months to 5 years. Twelve-month excess weight loss (EWL) for LVSG ranged from 69.7% to 83%, and for LRYGB, ranged from 60.5% to 86.4%. A number of studies reported slow weight gain between the second and third years of postoperative follow-up ranging from 1.4% to 4.2%EWL. This trend was seen to continue to 5 years postoperatively (8% to 10%EWL) for both procedures.
CONCLUSIONS: In conclusion, LRYGB and LVSG are comparable with regards to the weight loss outcomes in the short term, with LRYGB achieving slightly greater weight loss. Slow weight recidivism is observed after the first postoperative year following both procedures. Long-term reporting of outcomes obtained from well-designed studies using intention-to-treat analyses are identified as a major gap in the literature at present.
MATERIAL AND METHODS: Randomized controlled trials evaluating the effects of these 2 treatment modalities were searched from PubMed and other electronic databases between January 1991 and July 2018. The outcome variables analyzed included operating time, complications, recurrence of HH or wrap migration, reoperation, hospital stay and quality of life.
RESULTS: Five randomized controlled trials totaling 478 patients (suture=222, mesh=256) were analyzed. For reoperation variable, the odds ratio was significantly 3.26 times higher for the suture group. For recurrence of HH, the odds ratio for the suture group was nonsignificantly 1.65 times higher compared with the mesh group. Comparable effects were noted for all other variables.
CONCLUSIONS: Mesh repair seems to be superior to suture cruroplasty for large HH repair. Therefore, the routine use of mesh may be advantageous in selected cases.
DESIGN: A systematic review was conducted using electronic databases of CINAHL, PubMed, PsychINFO, Psychology and Behavioural Sciences Collection, SocINDEX and Web of Science for articles published until the 11th of January 2018.
ELIGIBILITY CRITERIA: All observational studies investigating the association between social support and depression among community-dwelling older adults in Asia were included.
PARTICIPANTS: Older adults aged 60 years and more who are living in the community.
EXPOSURE MEASURES: Social support.
OUTCOME MEASURES: Depression.
RESULTS: We retrieved16 356 records and screened 66 full-text articles. Twenty-four observational studies were included in the review. They consisted of five cohort studies and 19 cross-sectional studies. Social support was found to be measured by multiple components, most commonly through a combination of structural and functional constructs. Perceived social support is more commonly measured compared with received social support. Good overall social support, having a spouse or partner, living with family, having a large social network, having more contact with family and friends, having emotional and instrumental support, good support from family and satisfaction with social support are associated with less depressive symptoms among community-dwelling older adults in Asia.
CONCLUSIONS: There were 20 different social support measures and we applied a framework to allow for better comparability. Our findings emphasised the association between good social support and decrease depression among older adults. Compared with western populations, family support has a greater influence on depression among community-dwelling older adults in Asia. This indicates that the family institution needs to be incorporated into designed programmes and interventions when addressing depression in the Asian context.

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. Seven randomized controlled trials assessing the outcomes of PSR and POMR were analyzed in accordance with the PRISMA statement. The risk of bias was assessed using the Rob2 tool.
RESULTS: According to the pooled analysis, POMR significantly reduced the incidence of IH compared to the PSR (OR 5.82 [95% CI 2.69, 12.58] P
METHODS: RCTs comparing the early complication rates following LVSG and LRYGB between 2000 and 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included 30-day mortality, major and minor complications and interventions required for their management, length of hospital stay, readmission rates, operating time, and conversions from laparoscopic to open procedures.
RESULTS: Six RCTs involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on early major complications. A statistically significant reduction in relative odds of early major complications favoring the LVSG procedure was noted (p = 0.05). Five RCTs representing 633 patients (LVSG n = 317, LRYGB n = 316) reported early minor complications. A non-statically significant reduction in relative odds of 29 % favoring the LVSG procedure was observed for early minor complications (p = 0.4). However, other outcomes directly related to complications which included reoperation rates, readmission rate, and 30-day mortality rate showed comparable effect size for both surgical procedures.
CONCLUSIONS: This meta-analysis and systematic review of RCTs suggests that fewer early major and minor complications are associated with LVSG compared with LRYGB procedure. However, this does not translate into higher readmission rate, reoperation rate, or 30-day mortality for either procedure.
MATERIALS AND METHODS: Randomized controlled comparing MIE versus OE were searched from PubMed and other electronic databases between January 1991 and March 2019. Thirteen outcome variables were analyzed. Random effects model was used to calculate the effect size. The meta-analysis was prepared in accordance with PRISMA guidelines.
RESULTS: Four randomized controlled trials totaling 569 patients were analyzed. For MIE, there was a significantly reduction of 67% in the odds of pulmonary complications. For operating time, MIE was nonsignificantly 29 minutes longer. MIE was associated with nonsignificantly less blood loss of 443.98 mL. There was nonsignificant 60% reduction in the odds of total complications and 51% reduction in the odds of medical complications favoring MIE group. For delayed gastric emptying, there was a nonsignificant reduction of 75% in the odds ratio favoring the MIE group. For postoperative anastomotic leak, there was a nonsignificant increase of 48% in the odds ratio for MIE group. For gastric necrosis, chylothorax, reintervention and 30-day mortality, no difference was observed for both groups. There was a nonsignificant reduction in the length of hospital stay of 7.98 days and intensive care unit stay of 2.7 days favoring MIE.
CONCLUSIONS: MIE seems to be superior to OE for only pulmonary complications. All the other perioperative variables were comparable however, the trend is favoring the MIE. Therefore, the routine use of MIE presently may only be justifiable in high volume esophagogastric units.
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.
RESULTS: Fourteen RCTs totaling 3843 patients (LARR = 2096, ORR = 1747) were analyzed. Comparable effects were noted for all these histopathological variables except for the variable perforated rectum which favored ORR.
CONCLUSIONS: LARR compares favorably to ORR for rectal cancer treatment. However, there is significantly higher risk of rectal perforation during LARR compared to ORR.
