Portion Control Eating-a Determinant of Bariatric Outcomes

Long-Term Outcome of One-Anastomosis Gastric Bypass: 10-Year Follow-Up of a Single Institution Series

BACKGROUND

This study aims to evaluate the long-term efficacy, safety, nutritional status, and resolution of obesity complications of patients following one-anastomosis gastric bypass (OAGB).

METHODS

A retrospective observational study of patients who underwent OAGB in our center between January 2011 and December 2013 was performed.

RESULTS

During the study period, 152 patients underwent OAGB procedure in our center. Among them, 26 patients were lost to follow up and therefore were excluded from the data analysis. A total of 126 patients completed long-term follow-up of 10 years. The mean age of patients at baseline was 41 ± 12.5 years (range 20-68). At 10-year follow-up, mean excess weight loss (EWL) was 68.9 ± 22.8%. Mean BMI was 29.7 ± 12.9 kg/m2, representing an overall BMI reduction of 10.6 kg/m2. At 10-year follow-up among the 126 patients, 80% had resolution in DM, 71% had resolution in HTN, and 85% had resolution in OSA. There were no instances of severe malnutrition in the 126 patients in our study.

CONCLUSIONS

OAGB is an effective choice of bariatric/metabolic surgery for patients with higher BMI which provides good weight loss in terms of % TWL and % EWL without significant recurrent weight gain or inadequate weight loss with negligible nutritional deficiencies.

Undiagnosed Hyperglycemia Is a Potential Long-term Risk in Metabolic Surgery Patients: 7 Years Follow-up Study

INTRODUCTION

Diabetes is considered to be a surgically correctable illness. As glycemic control begins soon after surgery, the cessation of anti-diabetic medications is early. Patients believe that their diabetes has been "cured" and the need for blood sugar monitoring is forgotten, leading to undiagnosed hyperglycemia and risk of diabetes-related complications.

AIMS

To study the effect of bariatric surgery on long-term glycemic control and identify the patients with undiagnosed hyperglycemia.

METHODS

All patients with type 2 diabetes who underwent bariatric surgery at our center from January 2012 to December 2013 were included in the study. For each patient, demographic, preoperative, and postoperative data were retrospectively reviewed.

RESULTS

Out of the total 119 patients with diabetes, 91 patients underwent sleeve gastrectomy and 28 underwent Roux-en-Y gastric bypass. Diabetes status at 7 years of follow-up was possible in 53 (44.5%) patients: 44 (48.4%) in SG and 9 (32.2%) in RYGB groups. Overall, complete remission at 7 years was seen in 17 (32.1%) patients and partial remission in 12 (22.6%) patients. Amongst non-remitters (n = 24, 45.3%), 7 (13.2%) patients were on medications with good glycemic control (A1C < 6.5) while 8 (15.1%) patients had poor control (A1C > 6.5) despite ongoing medications. Additionally, 9 (17%) patients had poor glycemic control (A1C > 6.5) and were not receiving any anti-diabetic medications. Patients in whom follow-up A1C was unavailable and their diabetes status remain unknown were 66 (55.5%) at 7 years.

CONCLUSION

Our study clearly demonstrates high risk of undiagnosed hyperglycemia. Regular long-term follow-up in diabetic patients is even more desirable than amongst patients undergoing bariatric surgery for weight loss alone. Graphical abstract.

Prevalent bariatric dietary practices: Is India on the same page?

Background:

In the past decade, there has been an increase in the number and types of bariatric procedures in India. It is, thus, important to monitor prevalent bariatric practices.

Aim:

To identify prevalent pre- and post-operative dietary practices by bariatric professionals across India.

Materials and Methods:

Data regarding various pre- and post-surgery dietary practices were collected using an Internet-based survey. Thirty-three bariatric professionals including dietitians (n = 25) and surgeons (n = 8) across the country participated in the survey. The data were analysed, and prevalent dietary practices were identified.

Results:

Five (20%) dietitians were not involved in the pre-surgery consultation. Nineteen (70%) professionals put all patients on a low-calorie pre-surgery diet regardless of their body mass index, with a preference (n = 21; 77.7%) for liquid diet. Twenty-three (70%) professionals put patients on post-surgery liquid diet for 1–2 weeks. Thereafter, 28 (84.8%) professionals recommended soft diet for 2–4 weeks. Twenty-seven (81%) professionals used protein shakes (as opposed to dietary sources) as their primary source of protein for the first 3 months post-surgery. Fourteen (36%) professionals stopped protein shake supplements within 6 months post-surgery. Ten (30%) professionals reported whey protein aversions in >25% of the patients. Twenty-three (71%) professionals advocated a meal with <30% of carbohydrates for up to 1 year. Twenty-eight (84%) professionals used portion control method for meals.

Conclusion:

Our study reflects that prevalent dietary practices among Indian bariatricians are in line with national and international guidelines.

Is sleeve gastrectomy overcriticized? A single-center Indian experience with 5-year follow-up results

BACKGROUND

Bariatric surgery has seen a sharp rise in numbers worldwide in the last decade. Being a popular procedure, sleeve gastrectomy (SG) has been widely studied over the years for its efficacy, potential for weight regain, metabolic impact, and de novo gastroesophageal reflux disease (GERD).

OBJECTIVES

To evaluate clinical outcomes of laparoscopic SG after 5 years of follow-up in terms of weight loss, co-morbidity resolution, and GERD.

SETTING

The study was performed in a center of excellence in bariatric surgery in India.

METHODS

All patients who underwent laparoscopic SG from January 2012 to April 2013 were included in the study. Their demographic, preoperative, and postoperative data were prospectively maintained in Microsoft Excel and analyzed statistically.

RESULTS

Two hundred eighteen patients underwent SG in 2012-2013. Patients had a preoperative body mass index of 45.8 ± 9.5 kg/m² (mean ± standard deviation) and excess weight of 54.1 ± 25.6 kg. Percent excess weight loss was 87.6% ± 28.9% at 1 year, 77.2% ± 29.3% at 3 years, and 69.1% ± 27.8% at 5 years. Percent total weight loss at 1 year was 35.5% ± 7.6%, 31.4% ± 9.1% at 3 years, and 29.2% ± 9.8% at 5 years. At 5 years, 11 of 25 (44%) showed complete diabetic remission and 5 of 25 (20%) showed partial remission. De novo GERD was seen in 24 of 153 (15.7%) patients.

CONCLUSION

Our study reflects good outcomes after SG in terms of weight loss and diabetes resolution at 5-year follow-up, though GERD remains a matter of concern.
