Effect of laparoscopic sleeve gastrectomy on platelet count and mean platelet volume.

Objective: Several studies have reported an increase in platelet (PLT) count with chronic inflammation in the presence of obesity. Mean platelet volume (MPV) is an important marker for PLT activity. Our study aims to demonstrate if laparoscopic sleeve gastrectomy (LSG) has any effect on PLT, MPV and white blood cells (WBCs). Methods: A total of 202 patients undergoing LSG for morbid obesity between January 2019 and March 2020 who completed at least 1 year of follow-up were included in the study. Patients' characteristics and laboratory parameters were recorded preoperatively and were compared in the 6th and 12th months. Results: Two hundred and two patients (50% - female) with a mean age of 37.5 ± 12.2 years and mean pre-operative body mass index (BMI) of 43 (34.1-62.5) kg/m2 underwent LSG. BMI regressed to 28.2 ± 4.5 kg/m2 at 1 year after LSG (P < 0.001). The mean PLT count, MPV and WBC during the pre-operative period were 293.2 ± 70.3 103 cells/µL, 10.22 ± 0.9 fL and 7.8 ± 1.9 103 cells/µL, respectively. A significant decrease was seen in mean PLT count, with 257.3 ± 54.2 103cell/µL (P < 0.001) at 1 year post-LSG. The mean MPV was increased at 6 months 10.5 ± 1.2 fL (P < 0.001) and remained unchanged at 1 year 10.3 ± 1.3 fL (P = 0.9). The mean WBC levels were significantly decreased with 6.5 ± 1.7 103 cells/µL (P < 0.001) at 1 year. At the end of the follow-up, weight loss showed no correlation with PLT and MPV (P = 0.42, P = 0.32). Conclusion: Our study has shown a significant decrease in circulating PLT and WBC levels while MPV remained unchanged after LSG.

Is There a Relationship Between Helicobacter Pylori and GERD Before Laparoscopic Sleeve Gastrectomy?

AIM: The aim of this study is to determine the prevalence of Helicobacter pylori (HP) in patients before laparoscopic sleeve gastrectomy (LSG) and to reveal whether HP is associated with gastroesophageal reflux disease (GERD) before LSG. METHODS: The study included 435 patients who underwent primary LSG between April 2018 and September 2021. All patients underwent preoperative endoscopy. All patients were investigated for the presence of HP. No treatment for HP eradication was given to any of the patients. Patients were divided into 2 groups HP (+) and HP(-), and compared for GERD, complications, and weight loss before and after LSG. RESULTS: The mean age of the patients was 38.3±11 years (56.1% female), and the mean BMI was 44.2±7.1 kg/m 2 . Symptomatic GERD was found in 102 (23.4%) patients. Endoscopy showed hiatal hernia in 42 (9.7%) patients, and these patients also underwent hiatal hernia repair in the same session. HP was (+) in 125 (28.7%) patients. HP (+) patients were assigned to Group A, while HP (-) patients were assigned to Group B. In the preoperative period, the rate of symptomatic GERD was 22.4% (n=28/125) in Group A and 23.9% (n=74/310) in Group B ( P =0.74). The mean follow-up period was 17±5.7 (range, 12 to 28) months. The mean BMI decreased to 28.3±4.9 kg/m 2 at 12 months after LSG. Given the association between HP and GERD after LSG, it was 25.6% (n=32/125) in Group A and 20% (n=62/310) in Group B ( P =0.2). In addition, there was no difference between the 2 groups in terms of weight loss. CONCLUSION: This study showed no difference between patients with or without HP infection in terms of GERD before LSG.

Menetrier's disease in a morbid obese patient undergoing bariatric surgery: A case report.

INTRODUCTION AND IMPORTANCE: Menetrier's disease is a rare type of hypertrophic gastropathy characterized by the atrophy of the gastric parietal cells and dilatation of mucus releasing glands. Hereby, we present a morbid obese patient who has undergone laparoscopic sleeve gastrectomy (LSG) and he has also diagnosed with Menetrier's disease. CASE PRESENTATION: A 67-year-old male patient whose body mass index (BMI) was 39 kg/m2. Preoperative endoscopy was done. There were no pathologies except increased gastric mucosal folds. LSG was done. During the surgery it was noticed that gastric tissue was abnormally thick. After LSG completed, it was observed that there was an abnormal bleeding from the staple line. The staple line was oversewed with 3.0 V-Loc™ and bleeding was stopped. Pathology report was compatible with menetrier's disease. CLINICAL DISCUSSION: Hypoalbuminemia and H. pylori take an important place in diagnosis of Menetrier's disease, but H. pylori was not detected and albumin level was normal in our patient. For certain diagnosis full-thickness gastric biopsy is needed. The routine use of preoperative endoscopy in patients scheduled for bariatric surgery was still controversial until recently. CONCLUSION: This is the first case with menetrier's disease that has undergone LSG. Preoperative endoscopic evaluation before bariatric surgery is crucial. As in this case, it will be effective in terms performing additional intraoperative precautions when necessary and preventing possible complications.
