RESUMEN
The prevalence of diabetes type 2 (T2DM) and obesity is growing exponentially and becoming a global public health problem. The enzymes of glucose metabolism play a role in the pathogenesis of insulin resistance and T2DM. A pathophysiological link between different dietary patterns, HFD, obesity, T2DM and the enzymes of glucose metabolism can be used as a potential target in therapeutic strategies for the treatment of obesity, and T2DM. The aim of this study was to measure the impact of DJOS bariatric surgery and different types of dietary patterns on glycogen synthase kinase 3 α (GSK-3α), glycogen phosphorylase (PYGM, PYGL), and phosphofructokinase (PFK-1) concentrations in liver and soleus muscle tissues of rats. After 8 weeks on a high-fat diet (HF) or control diet (CD), rats underwent duodenal-jejunal omega switch (DJOS) or SHAM (control) surgery. After surgery, for the next 8 weeks, half of DJOS/SHAM animals were kept on the same diet as before, and half had a changed diet. The concentrations of GSK-3α, PYGM, PYGL and PFK-1 were measured in the soleus muscles and livers of the Sprague-Dawley rats. The type of diet applied before/after surgery had stronger impact on levels of selected metabolic enzymes than DJOS or SHAM surgery. The impact of DJOS surgery was visible for GSK-3α and PYGL concentration in the liver but not in the soleus muscle tissue. The type of bariatric surgery had an impact on liver GSK-3α concentration in all studied groups except the CD/CD group, where the impact of diet was stronger. DJOS bariatric surgery influenced the level of PYGL in the livers of rats maintained on the CD/CD diet but not from other groups. The dietary patterns applied before and after bariatric surgery, had a stronger impact on enzymes' concentrations than DJOS surgery, and the strong, deleterious effect of an HF was observed. A change of the diet per se showed a negative impact on the enzymes' tissue concentration.
RESUMEN
Objective To explore the application value of laparoscopic gastric plication (LGP) combined with duodeno-jejunal omega switch (DJOS) in modified adjustable gastric banding.Methods The retrospective and descriptive study was conducted.The clinical data of a female 46-year-old patient who had failure to undergo the adjustable gastric banding in the Hospital of Ludwig Maximilian University from December 2016 to December 2018 were collected.LGP and DJOS were performed in two-stages after completion of preoperative examinations.Observation indicators:(1) surgical and postoperative situations;(2) follow-up.Follow-up using outpatient examiantion and telephone interview was performed to collect the information of body mass index (BMI),insulin therapy,and long-term complications until December 2018.Count data were represented as absolute numbers.Results (1) Surgical and postoperative situations:the patient underwent LGP in the first stage and DJOS in the second stage successfully.For the LGP,the operation time,time of intestinal reconstruction,volume of intraoperative blood loss,time to first flatus,time to drainage tube removal,time to resume to normal diet,and duration of postoperative hospital stay were 96 minutes,58 minutes,210 mL,32 hours,48 hours,42 days,and 3 days,respectively.For the DJOS,the above indicators were 148 minutes,117 minutes,260 mL,47 hours,72 hours,21 days,and 7 days,respectively.There was no complication occurred in either LGP or DJOS.(2) Follow-up:the patient was followed up for 24 months after LGP.The BMI of this patient decreased to 45.3 kg/m2 at 6 months after LGP,and decreased to 37.2 kg/m2 at 18 months after DJOS.Insulin therapy was discontinued.There was no long-term complication such as malnutrition,dumping syndrome,or biliary reflux.Conclusion LGP combined with DJOS can enrich treatment methods of obese patient with BMI >50 kg/m2,which offers a safer surgical procedure option for patients after gastric binding.
RESUMEN
PURPOSE: To study the effect of duodenal-jejunal omega switch (DJOS) in combination with different dietary patterns on the retinol-binding protein (RBP4), fetuin-A, and fibroblast growth factor 21 (FGF21) plasma levels and their hepatic gene expressions in rats. METHODS: A high-fat diet (HF) was given to 28 rats and 28 more were fed with a control diet (CD) for 2 months. After that, half of each group underwent either DJOS or SHAM surgery. For the next 2 months, half of the animals in each operation group were kept on the same diet as before and half of them had the diet changed. After 16 weeks of the experiment RBP4, fetuin-A, and FGF21 plasma levels as well as liver Rbp4, Ahsg, and Fgf21 gene expressions were measured. RESULTS: DJOS had a reductive impact on plasma levels of RBP4, fetuin-A, and FGF21 and Rbp4, Ahsg, and Fgf21 relative gene expression in the liver when compared to SHAM. The HF/HF group expressed significantly higher RBP4 and fetuin-A plasma levels in comparison to the control. The HF diet used before and/or after surgery led to upregulation of Rbp4, Ahsg, and Fgf21 relative gene expression. The lowest levels of analyzed parameters were observed in the CD/CD group. CONCLUSIONS: The efficiency of DJOS surgery, measured by hepatokines' plasma levels and their gene expressions in the liver, depends on the type of diet applied before and after surgery. Manipulation of dietary patterns can lead to marked improvements in metabolic profile after DJOS surgery.

BACKGROUND: Pathophysiological links between inflammation, obesity, and adipokines can be used for the treatment of metabolic dysregulation. AIMS: To examine the influence of duodenal-jejunal omega switch surgery in combination with different diet patterns on plasma concentrations of fatty acid-binding protein 4 (FABP4), C-reactive protein (CRP), leptin, and chemerin. METHODS: After 8 weeks on a high-fat diet (HF) or control diet (CD), rats underwent surgery. Duodenal-jejunal omega switch (DJOS) with an exclusion of one-third of intestinal length and SHAM surgery were performed. For the next 8 weeks, 50% of DJOS/SHAM animals were kept on the same diet as before (HF/DJOS/HF, HF/SHAM/HF, CD/DJOS/CD, and CD/SHAM/CD), and 50% had a changed diet (HF/DJOS/CD, HF/SHAM/CD, CD/DJOS/HF, and CD/SHAM/HF). FABP4, CRP, leptin, and chemerin were assessed using ELISA kits. RESULTS: FABP4: significant differences between DJOS and SHAM were observed in animals maintained on CD/CD; CRP: varied between DJOS and SHAM groups maintained on HF/HF, CD/CD, and CD/HF; leptin and chemerin levels: DJOS lowered leptin and chemerin plasma levels versus SHAM, while HF/HF, CD/HF, and HF/CD significantly increased leptin and chemerin plasma levels when compared to CD/CD. CONCLUSIONS: The beneficial effect of DJOS surgery is stronger than proinflammatory conditions caused by an HF obesogenic diet.

BACKGROUND: Despite excellent results of bariatric surgery in the treatment of type 2 diabetes and weight loss in human subjects, some patients do not obtain desired results. One of the reasons for this is that not all patients follow caloric intake recommendations. AIM: The aim of this study was to investigate the effect of duodenojejunal omega switch (DJOS) surgery on body weight, glucose tolerance, and incretins in rats. METHODS: DJOS and SHAM surgery were performed on rats maintained for 8 weeks on high-fat diet (HF) and control diet (CD), respectively. After surgery, four groups were kept on the same diet as before the surgery, and four groups had a changed diet (CD vs. HF and HF vs. CD) for the next 8 weeks. Glucose tolerance, insulin tolerance, glucose-stimulated insulin, glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide/glucose-dependent insulinotropic polypeptide (GIP) secretion, food intake, and body weight were measured. RESULTS: A change of diet after surgery resulted in reduced glucose tolerance. Plasma insulin levels were lowered between DJOS and SHAM surgeries for the HF/HF and CD/HF groups. DJOS surgery did not reduce body weight in the studied groups, irrespective of diet. In the HF/HF group, ΔGLP-1 was lower for DJOS surgery in comparison with other groups. Differences of weight changes were observed for groups HF/HF and HF/CD. After DJOS surgery, ΔGIP was lower in the CD/HF group compared with HF/HF. CONCLUSIONS: Our results show that applications of different types of diets, before and after surgery, is a sensitive method for studies of mechanism of glucose intolerance after DJOS surgery.

OBJECTIVE: Ileal transposition (IT) procedure leads to higher secretion of incretin hormones what is associated with a beneficial metabolic effect. However, IT will also have an influence on the related jejunum and ileum function. The aim of this research was to investigate the morphology of the jejunum and transposed ileum with the use of light and transmission electron microscopy (TEM) in order to determine the local alternations in the intestine resulting from the transposition. METHODS: Twenty male, 8-week-old, obese Zucker rats underwent IT and six of them sham surgery. To compare both groups, the transection was made at all corresponding ileum positions among both groups of animals. The ileal anastomoses among the rats of sham procedure were subsequently formed accordingly without IT. Three months following the surgery, the tissue samples of jejunum and ileum were harvested. RESULTS: A significant increase in villus length, a decrease in the crypt depth, and an increased thickness of mucosa-muscularis-serosa (MMS) as well as cellular hyperplasia, with increased mitochondrial density of the transposed ileum segment, were observed among the group of rats which underwent IT comparing to the ones undergoing sham surgery. In rats undergoing IT, microvillus degeneration in jejunum regions was observed. CONCLUSIONS: Ileal transposition alters the morphology and ultrastructure of the ileum as well as the jejunum. Given that the microvillus membrane represents an important aspect of the enterocyte functions, a further biochemical and molecular research is necessary in order to assess whether the observed changes are beneficial or not and to explore the phenomenon of gut adaptability after metabolic surgery.

PURPOSE: We compared the outcome of hybrid laparoscopic pylorus-preserving pancreatoduodenectomy (lapPPPD) and open PPPD (oPPPD) in a retrospective case-matched study. METHODS: Patients operated from 2010 to 2013 by lapPPPD were matched 1:1 for age, sex, histopathology, American Society of Anesthesiologists category and body mass index to oPPPD patients operated from 1996 to 2013. RESULTS: Patients eligible for lapPPPD are a risk group due to a high rate of soft pancreata. Complication rate and mortality were comparable to oPPPD. There was a significantly reduced transfusion requirement and a trend towards shorter operation time, less delayed gastric emptying, and reduced hospital stay. The main reason for conversion was portal venous tumor adhesion. Patient selection changed and operation time and hospital stay decreased with the surgeons' experience. CONCLUSION: In selected patients, a hybrid laparoscopic technique of pancreatoduodenectomy is feasible with complication rates comparable to the open procedure. There seem to be advantages in terms of transfusion requirement, operation time, and hospital stay.

INTRODUCTION: Minimally invasive surgery has conquered almost all niches of abdominal surgery. Even though some surgeons have shown equal lymph node ratio and oncologic radicality for laparoscopic surgery of pancreatic cancer, oncologic surgeons still take reasonably conservative views of the use of minimally invasive techniques for the treatment of pancreatic cancer, especially if located in the head of the pancreas. Laparoscopic abdominal approaches on the other hand have a potential advantage of better visualization, decreased postoperative pain, decreased use of analgetics, and shorter hospital stay. We demonstrate in this technical surgical report the first description of a total laparoscopic pancreatoduodenectomy and reconstruction via laparoscopic pancreatogastrostomy in a 74-year-old female patient with a periampullary tumor. DISCUSSION: After pylorus-preserving pancreatoduodenectomy by superior mesenteric artery, first approach including standard lymphadenectomy, the reconstruction involved total laparoscopic end-to-side running-suture hepaticojejunostomy, double-layer running-suture antecolic pylorojejunostomy to the first jejunal loop, and pancreatogastrostomy via posterior gastrotomy secured by two anchoring and purse-string sutures.
