Postoperative Body Mass Index Changes in Gastric Cancer Patients according to Reconstruction Type: Effectiveness of Long Jejunal Bypass on Weight Loss in Obese Patients after Distal Gastrectomy

The aim of this study was to investigate and compare the change of body mass index (BMI) in patients after gastrectomy for cancer according to the type of reconstruction. BMI was followed in 260 patients who had undergone curative surgery for gastric cancer from March 2003 to December 2009. The procedures were Billroth I in 63 patients, Billroth II in 52 patients, Roux-en-Y in 54 patients, long Roux-en-Y (bypassed proximal jejunum over 100 cm) in 47 patients, and total gastrectomy in 44 patients. BMI reduction was greatest in the total gastrectomy group at postoperative 6 months, 1 year, and 2 years. Postoperative 3-year BMI reduction was greatest in the long Roux-en-Y group. BMI reductions of the total gastrectomy and long Roux-en-Y groups were similar during the follow-up period. Among the subtotal gastrectomy groups, BMI reduction was greatest in the long Roux-en-Y group, and there was statistical significance in comparing with Billroth I and II groups, but no statistical difference with the Roux-en-Y group. Given the limitations of patient number and follow-up period, it can be concluded that obese patients with gastric cancer not requiring total gastrectomy may benefit from long Roux-en-Y reconstruction with adequate BMI reduction and accompanying health improvement.

Long-term effect of radical gastrectomy on nutrition and immunity

The long-term effects of gastrectomy on the nutritional and immunologic status were prospectively studied in 79 gastric cancer patients who underwent curative gastrectomy and were followed by us after operation for an average of 5 years and 3 months. The percent of actual weight to pre-illness normal weight was lower than 95% in 80% of all study patients. Retinol binding protein, prealbumin, and albumin were lower than normal in 17%, 26%, and 26% of the patients, respectively. The mean values of the percent normal weight, retinol binding protein, and prealbumin were significantly lower in the totally gastrectomized patients than in the subtotally gastrectomized ones (P<0.01). The procedures of reconstruction did not affect the nutritional status except for the prealbumin level which was significantly decreased in Roux-en-Y cases than in interposed cases of totally gastrectomized patients. Cell-mediated immunological alterations after gastrectomy were observed in 31%, 37%, and 71% of all patients for OKT3 subpopulation, OKT4/OKT8 ratio, and blastogenesis by phytohemagglutinin, respectively. A multivariate analysis revealed that the long-term immunity of the gastrectomized patients after operation was not affected by the levels of albumin and rapid turnover proteins but by the splenectomy and weight loss they underwent.

Abstract Objective To assess the effects of gastric bypass with different types of anastomosis on type 2 diabetes mellitus (T2DM). Methods From June 2006 to February 2009, 61 patients with gastric lesions combined with type 2 diabetes mellitus performed gastrectomy were prospectively assigned into Billroth ?? group (n=11), Billroth ?? group (n=26) and Roux-en-Y group (n=24) in Fuzhou General Hospital of Nanjing Military Command. The pre- and postoperative clinical parameters associated with glycometabolism and body mass index were measured during a 6-month follow-up period. Results Fasting blood glucose and glycated hemoglobin levels were significantly decreased after surgery in both Billroth ?? and Roux-en-Y groups (P<0.01 or P<0.05). At 3 and 6 months, patients in both Billroth?? and Roux-en-Y groups had significantly increased fasting C-peptide and significant improved oral glucose tolerance test (P<0.01 or P<0.05). The changes of those parameters above in Roux-en-Y group were greater than those in Billroth ?? group(P<0.01 or P<0.05). However, the effects were not shown in Billroth ?? group through the entire follow-up period. T2DM control rate in Roux-en-Y group was higher than that in Billroth ?? and Billroth ?? group (P<0.01 or P<0.05). Conclusion As compared with Billroth ?? and Billroth ?? reconstruction after gastrectomy, Roux-en-Y gastric bypass seems to be more effective on T2DM control. The therapeutic effect of gastric bypass is independent on loss of body weight. Roux-en-Y gastric bypass may be as a potential management option for T2DM.     

Usefulness of reconstruction with jejunal pouch in total gastrectomy for gastric cancer in early improvement of nutritional condition

BACKGROUND: Roux-en-Y reconstruction with a jejunal pouch is a modified standard procedure in total gastrectomy for gastric cancer. The aim of the current study was to evaluate the usefulness of the reconstruction using a jejunal pouch in subsequent improvement of the nutritional condition of patients with gastric cancer after total gastrectomy. METHODS: Sixteen patients with gastric cancer treated by total gastrectomy and reconstruction with simple Roux-en-Y from January 1993 to December 1996 and 14 patients treated by total gastrectomy and reconstruction with Roux-en-Y and jejunal pouch from January 1997 to December 1998 were investigated in regard to postoperative heartburn, changes in the body weight, and prognostic nutritional index. RESULTS: Postoperative heartburn occurred in 1 patient (7.1%) among patients treated with Roux-en-Y and jejunal pouch and 3 (18.8%) among patients treated with simple Roux-en-Y. The body weight ratio at 1 year after operation in patients treated with Roux-en-Y and jejunal pouch (88.2% +/- 4.2%) was significantly higher than that in patients treated with simple Roux-en-Y (80.0% +/- 4.6%; P <0.01). The prognostic nutritional index ratios for patients treated with Roux-en-Y and jejunal pouch at 1 and 3 months after operation were 93.9% +/- 9.1% and 101.7% +/- 11.0%, respectively, and were significantly higher than that in patients treated with simple Roux-en-Y (86.2% +/- 8.8% and 88.1% +/- 8.2%, P <0.05 and P <0.01, respectively). CONCLUSIONS: Reconstruction using a jejunal pouch in total gastrectomy is useful for an early improvement of the nutritional condition of patients with gastric cancer.

Laparoscopic Gastric Bypass with Subtotal Gastrectomy for a Super-Obese Patient with Biermer Anemia

Laparoscopic Roux-en-Y gastric bypass (RYGBP) is a common procedure for morbid obesity. After RYGBP, the bypassed stomach is unavailable for follow-up. Biermer anemia is an autoimmune atrophic gastritis inducing vitamin B12 deficiency and it is a risk factor for gastric carcinoma.A 41-year-old woman with a long history of morbid obesity presented with a BMI of 56 kg/m². She had anemia (Hb 9.9 g/dL), and atrophic gastritis was found endoscopically. We performed a laparoscopic RYGBP with subtotal gastrectomy, to avoid the risk of gastric carcinoma in the bypassed stomach.The patient was discharged 9 days after the operation without complication. At 18 months follow-up, her BMI was 39 kg/m² (50% excess weight loss). Laparoscopic RYGBP with subtotal gastrectomy is a safe treatment for morbid obesity, which should be considered for patients with a risk factor for gastric carcinoma.     

Predictors of nonalcoholic steatohepatitis in patients undergoing bariatric surgery: when is liver biopsy indicated?

BackgroundNonalcoholic fatty liver disease is a frequent accompaniment of morbid obesity. A component of nonalcoholic fatty liver disease, steatosis, can, on occasion, lead to nonalcoholic steatohepatitis (NASH). Bariatric surgery has been shown to alter the course of this disease. Intraoperative liver biopsies might identify patients with NASH for more careful follow-up. We sought to determine noninvasive preoperative indicators of NASH.MethodsThe patients scheduled for bariatric surgery underwent a preoperative assessment. The study variables included age, gender, race, body mass index, diabetes mellitus, hypertension, and the results of serum liver function tests and triglyceride, cholesterol, iron, and prealbumin measurements. Univariate and multivariate analyses were performed to identify significant variables associated with NASH as determined by subsequent core liver biopsies taken during open Roux-en-Y gastric bypass.ResultsA total of 139 patients were entered into the study. NASH or NASH-associated fibrosis was found in 57 patients (41%). On univariate analyses, male gender (odds ratio [OR] 2.46, P = .06), diabetes mellitus (OR 2.60, P = .009), elevated serum triglyceride levels (OR 1.003, P = .02), elevated gamma glutamyl transferase (OR 1.015, P = .01), and decreased prealbumin (OR 0.94, P = .04) correlated with the presence of NASH. On multivariate analysis, only increased triglycerides (OR 1.004, P = .04) and decreased prealbumin (OR 0.88, P = .005) correlated with the presence of NASH.ConclusionNASH is a frequent accompaniment of morbid obesity in patients undergoing bariatric surgery. Univariate and multivariate analyses of the clinical parameters studied could not identify strong predictors of biopsy-verified NASH. Therefore, intraoperative biopsy remains instrumental in diagnosing NASH and providing information for additional follow-up.
