The Successful Implementation of a Modified Enhanced Recovery After Surgery (ERAS) Program for Bariatric Surgery in a South African Teaching Hospital.

BACKGROUND: This study assessed the impact of strict adherence to perioperative pathways incorporating an enhanced recovery after surgery protocol on the outcomes of bariatric surgery at our center. METHODS: Prospective data were collected on 62 patients undergoing bariatric surgery between January 2011 and March 2016. Outcomes were compared between those who adhered to the perioperative pathway and those who did not. RESULTS: Fifty-three patients underwent laparoscopic sleeve gastrectomy, and 9 patients underwent Laparoscopic Roux-en-Y Gastric Bypass. The majority of subjects were female individuals (n=45; 72.6%). The mean age (±SD) was 40.5±9.8 years (range, 21 to 59 y). The mean preoperative body mass index (BMI) was 54.8±11.0. The mean BMI loss from baseline was 14.8 kg/m (-15.9 kg m; P<0.001). There were no deaths, and there were only 2 postoperative complications (1 intra-abdominal bleeding postoperatively requiring reoperation and 1 patient requiring CPAP support in intensive care unit). Full adherence was achieved in 53 (85.5%) patients with a mean length of stay (LOS) of 3±0.8 days. The nonadherent group had a significantly longer LOS of 4±3.2 days (P=0.049). The time since last follow-up visit was on average 4.4±5.6 months in the fully adherent group and significantly longer in the nonadherent group at 10.6±11.3 months (P=0.013). Age, race, sex, and BMI did not significantly impact on adherence. The mean LOS among morbidly obese and super obese patients was comparable at 3 and 3.3 days, respectively (P=0.442). CONCLUSION: Adherence to enhanced recovery after surgery pathways was associated with a significantly shorter hospital stay and better follow-up in our surgical unit.

Self-Expandable Metal Stents in Esophageal Cancer in a High HIV Prevalence Area: A Survival Analysis and Evaluation of Prediction Scores.

INTRODUCTION: Esophageal cancer (EC) and human immunodeficiency virus (HIV) are common in parts of South Africa. Squamous cell carcinoma of the esophagus in KwaZulu-Natal, South Africa presents generally in advanced stages and is mostly palliated by the deployment of self-expandable metal stent (SEMS). This study analyses these relationships between coexistent HIV infection, SEMS deployment, and survival scores. METHODOLOGY: Information on patients managed with SEMS between October 2013 and December 2014 was retrieved from a prospective database of EC and followed up until April 2015. Data collected included demographics, HIV status, clinical presentation, prognostic indicators, management, and survival. Prognostic factors were calculated in relation to outcome. RESULTS: One hundred five patients with EC had median ages of 61 (SD±11.4) and median body mass index of 17.45. Squamous cell carcinoma of the esophagus was diagnosed in 90 patients and adenocancer in 7 patients. Tumors were located in the proximal (10), middle (64), and distal (29) esophagus. Stage IV EC had a significant shorter survival of fewer than 3 months compared with stage III cancer (P=0.009). A C-reactive protein >150 mg/L was 3.6 times more likely to predict survival of fewer than 3 months than a value <50 mg/L (P=0.035). A proximal stent position significantly predicted shorter survival (P=0.035). The Steyerberg prognostic score proved ineffective in predicting survival of <3 months in our setting. Of the 84 patients tested for HIV, 23 were positive. Thirteen patients were on highly active antiretroviral therapy surviving significantly longer than those without this medication (P=0.036). CONCLUSIONS: Stage IV cancer and C-reactive protein >150 predicted survival of <3 months significantly better than the Steyerberg prediction score or other markers. Highly active anti-retroviral therapy had a positive impact on survival; however, SEMS placement in the proximal esophagus was associated with shorter survival.
