Abstract

Background

Bariatric surgery has been shown to be effective in severely obese patients with type 2 diabetes mellitus (T2DM).

Objective

Evaluate the long-term efficacy of biliopancreatic diversion (BPD) for the treatment of T2DM depending on the preoperative duration of T2DM.

Setting

University Hospital.

Methods

Retrospective analysis investigating 2 subsets of severely obese patients who had undergone BPD from 1984 to 1995. The first included 52 patients with a preoperative T2DM duration of ~1 year (SD group – 49 on oral agents and 3 on insulin), and the second included 68 patients who had been diabetic for>5 years before BPD (LD group – 52 on oral agents and 16 on insulin). Postoperatively, T2DM was regarded as in remission when fasting serum glucose (FSG) was lower than 100 mg/dL on regular diet and without antidiabetic therapy.

Results

In the SD patients, the number of individuals without T2DM remission were lower both at 5–10 (0/31, 0% of patients, versus 8/54, 15% of patients, p<.04) and at>15 years (1/28, 3% of patients, versus 10/41, 24% of patients, p<.0012). Furthermore, after BPD, the number of patients with dyslipidemia strongly reduced (p<.001) in both groups, values at 5–10 years remaining very similar to those observed at>15 years.

Conclusion

These results indicate that severely obese patients with longer T2DM duration have a worse metabolic outcome maintained at long and very long term following BPD.

Introduction

In recent years, strong evidence of remission or sharp improvement of diabetic status in obese type 2 diabetics after all types of bariatric surgery has emerged [1], [2], [3]. The metabolic outcome seems to be substantially related to the extent of weight reduction, the best results being observed following the surgeries that induce consistent loss of body mass: after adjustable gastric banding, only a 20–30% of type 2 diabetes patients succeed in normalizing or reducing fasting serum glucose level; after laparoscopic Roux-en-Y gastric bypass (LRYGBP) or biliopancreatic diversion (BPD), a successful metabolic outcome after the surgery is observed in 60–70% and 85–95% of the operated patients, respectively, most likely from postoperative changes in enterohormonal pattern [4], [5], [6], [7], [8]. Nevertheless, few data are available to evaluate the metabolic results’ stability over a very long term [9].

The purpose of this retrospective analysis is to ascertain the maintenance of a normal metabolic state at very long term in severely obese patients and the role of preoperative diabetes duration in the long term diabetes remission following BPD.

Material and methods

The analysis was carried out in the vast cohort of severely obese patients with type 2 diabetes having consecutively undergone BPD at the Surgical Department of Genoa University, Italy, from May 1984 to May 1999 [10]. Patients were considered to have type 2 diabetes when fasting serum glucose concentration (FSG) was higher than 125 mg/dL either before or during their preoperative evaluation and/or if they were on chronic use of antidiabetic therapy. Among this cohort, 2 groups of patients were

Results

In both the SD and LD group, at 5–10 years following the surgery, a sharp and significant reduction of both body weight (BW) and body mass index (BMI) were found. These values remained substantially unchanged at>15 years; the percent of weight loss at 5–10 years was substantially similar to that observed at>15 years (Table 1). Likewise, the values of FSG, total cholesterol, and triglyceride levels decreased at 5–10 years in both groups, which strictly maintained at>15 years, and an increase of

Discussion

There is ample evidence in the literature that all types of bariatric surgeries lead to an improvement in the diabetic status in obese individuals, with BPD and Roux-en-Y gastric bypass leading to better metabolic outcome compared with a purely restrictive procedure like gastric banding [1], [2], [12], [13], [14]. However, few results at very long term are available, and very little work has been done to study and establish the preoperative factors that can reliably predict postoperative

Conclusion

In obese patients with overt type 2 diabetes undergoing BPD, the diabetes duration and the type of therapy are factors that predict the very long term postoperative metabolic outcome. In the population under study, the rate of diabetes remission is significantly lower in patients with long-duration diabetes before surgery compared with those patients who had a recent diagnosis of diabetes. In the latter group, whose diagnosis of diabetes was ~1 year before surgery, diabetes remission was

      Patients with short duration of diabetes were more likely to have T2D remission at 5 to 10 (100%) and >15 (97%) years. When further divided by diabetes treatment, patients using insulin before surgery had remission rates of 64.8% at 5 to 10 years and 60% at >15 years [10]. Our results were contrary to findings by Scorpinaro et al. [30], which suggest that disease duration was only a predictor of early T2D remission when type of preoperative glycemic treatment was not considered [30].

      For this pilot observational retrospective analysis, 41 patients with T2DM undergoing bariatric surgery were enrolled from July 2007 to July 2009 at the Surgery Department of the Ospedale Policlinico San Martino in Genoa, Italy. After a multidisciplinary evaluation (including a psychologist, a psychiatrist, a diabetologist, a dietitian and a nurse), patients underwent either biliopancreatic diversion (BPD) or Roux-en-Y gastric bypass (RYGB), as described elsewhere [7,8]. Briefly, BPD was achieved by partial (two-thirds) distal gastrectomy and small-bowel transection 300 cm proximal to the ileocaecal valve.

      Finally, effects of leptin stimulation on human primary neutrophil degranulation and integrin expression were investigated in vitro. This pilot observational retrospective study has been performed in a single-center cohort enrolling 47 patients with T2DM undergoing bariatric surgery from July 2007 to July 2009 at the Surgical Department of Genoa University Hospital as already reported [11,12]. After a first analysis, serum samples were available for 44 of 47 patients.

      Bariatric operations have demonstrated to be an effective method to treat T2DM [26]. All successful operations significantly improve insulin resistance and diabetes, but those based on malabsorptive principles get higher resolution rates [27]. SASI Bypass comprises all the possible mechanisms involved in diabetes improvement, which are a function restriction responsible of reduction in the caloric intake, a rapid entrance of undigested chyme into the distal intestine which amplifies the nutritive stimulation of the distal gut and at the same time a smaller part of the meal empties through the duodenum, diminishing the nutritive overstimulation of the proximal gut but not reducing it completely, and in the short run, maintained weight loss.
