Introduction Recently laparoscopic sleeve gastrectomy has gained increased popularity both as a primary operation for weight reduction and as a revisional procedure after failed restrictive bariatric surgery. On the contrary, the conversion to laparoscopic Rouxen-Y gastric bypass is a solution with some drawbacks such as long operative time and higher complication rates. Aim To find an evidence of BMI reduction and/or less surgical complications following revisional surgeries (laparoscopic Roux-en-Y gastric bypass, mini gastric bypassone-anastomosis gastric bypass, and laparoscopic sleeve gastrectomy) after failed restrictive bariatric surgeries (vertical banded gastroplasty or laparoscopic adjustable gastric banding). Patients and methods A retrospective observational secondary study was performed on published research and meta-analysis for each eligible study according to inclusion and exclusion criteria. Results The 24-, 36-, and 48-month postoperative extra weight loss percentage was lower in sleeve gastrectomy than gastric bypasses, with overall significantly better decrease. Conversely, when comparing RYGB with mini gastric bypass at 12 months after conversion, there was more extra weight loss percentage for RYGB, with significant overall difference. Conclusion Our meta-analysis showed that both sleeve gastrectomy and gastric bypasses as revisional operations had no significant difference regarding postoperative leakage and major bleeding.

This research investigates the relationship between enterprise environmental factors (EEFs) and programme management (PgM) resources, and subsequently how PgM resources and sustainability integrate into social enterprise. With a resource-based view (RBV) concept as the theoretical starting point, a systematic literature review identified EEFs relating to PgM resources, and PgM resources relating to sustainability in private and public organisations. A mixed-method research approach was used that is founded on a sequential exploratory strategy. In the preliminary phase, meta qualitative analysis was conducted; in the second phase, 16 semi structured interviews were undertaken to customise and confirm the concepts by using thematic analysis within 4 selected case studies. In the final phase, the model was validated by a survey that returned (n = 302) completed questionnaires from around Pakistan, and the used method of analysis was PLS-SEM. These research findings highlight that PgM resources within social enterprises are highly influential and dependent on external and internal EEFs, and that PgM resources are critical to consider for social enterprise sustainability. In addition, this study highlights that PgM resources positively influence social, economic, and environmental sustainability in SEs. Furthermore, this study developed a validated novel theoretical framework. [ABSTRACT FROM AUTHOR]
