Abstract
Total gastrectomy and R&Y reconstruction is the standard treatment of gastric cancer except distal form one. Malnutrition is a common adverse effect of this technique, and in this study, we preset a novel technique in order to help to reduce the rate of it. We use seven dogs as participants and after total gastrectomy; we used the 10 cm of the ileum and its concomitant cecum as a neo-stomach in them. For 3 months, the dogs were evaluated in nutrition status. Three of the dogs died-one due to endocarditis and two due to internal hernia. No anastomosis leakage or stricture was seen and there were no unusual neo-stomach dilation or food stasis. This technique can help the nutrition status of total gastrectomy patients but needs more comparative human studies.

Total gastrectomy-induced reductions in food intake and weight are counteracted by rikkunshito by attenuating glucagon-like peptide-1 elevation in rats. Surgery 2016; 159:1342-50. [PMID: 26775072 DOI: 10.1016/j.surg.2015.12.003] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2015] [Revised: 11/16/2015] [Accepted: 12/06/2015] [Indexed: 12/25/2022]
Abstract
BACKGROUND Decrease in appetite and weight after total gastrectomy in patients with gastric cancer leads to a decrease in quality of life, increased mortality, and may necessitate discontinuation of adjuvant chemotherapy. The aim of this study is to determine whether rikkunshito, a Japanese herbal medicine, increases food intake and weight after gastrectomy in rats. METHODS Male rats underwent gastrectomy followed by roux-en-Y reconstruction or sham operation and were then treated with rikkunshito for 14 days starting on postoperative day 3. Daily food intake, weight, plasma glucagon-like peptide-1 (GLP-1), and ghrelin levels were measured. A pilot study to measure pre- and postoperative plasma GLP-1 levels was conducted in patients who underwent total gastrectomy for gastric cancer. RESULTS Administration of rikkunshito after gastrectomy in rats significantly increased food intake and weight, which continued for at least 2 weeks after treatment. Both fasting and postprandial plasma GLP-1 levels were increased markedly after gastrectomy compared with sham-operated animals. Increased GLP-1 levels in rats after gastrectomy were suppressed markedly by rikkunshito. rikkunshito had no significant effect on plasma ghrelin levels after gastrectomy. Treatment with a GLP-1 receptor antagonist significantly improved food intake and weight after gastrectomy. Plasma fasting GLP-1 levels in patients with gastric cancer were increased greatly after gastrectomy on postoperative day 1. CONCLUSION Administration of rikkunshito suppresses plasma GLP-1 levels after total gastrectomy, which is associated with recovery from reduced food intake and weight in rats.

Abstract
Despite considerable scientific progress on the biological systems that regulate energy balance, we have made precious little headway in providing new treatments to curb the obesity epidemic. Diet and exercise are the most popular treatment options for obesity, but rarely are they sufficient to produce long-term weight loss. Bariatric surgery, on the other hand, results in dramatic, sustained weight loss and for this reason has gained increasing popularity as a treatment modality for obesity. At least some surgical approaches also reduce obesity-related comorbidities including type 2 diabetes and hyperlipidemia. This success puts a premium on understanding how these surgeries exert their effects. This review focuses on the growing human and animal model literature addressing the underlying mechanisms. We compare three common procedures: Roux-en-Y Gastric Bypass (RYGB), vertical sleeve gastrectomy (VSG), and adjustable gastric banding (AGB). Although many would group together VSG and AGB as restrictive procedures of the stomach, VSG is more like RYGB than AGB in its effects on a host of endpoints including intake, food choice, glucose regulation, lipids and gut hormone secretion. Our strong belief is that to advance our understanding of these procedures, it is necessary to group bariatric procedures not on the basis of surgical similarity but rather on how they affect key physiological variables. This will allow for greater mechanistic insight into how bariatric surgery works, making it possible to help patients better choose the best possible procedure and to develop new therapeutic strategies that can help a larger portion of the obese population.

Abstract
BACKGROUND Alterations in gastrointestinal tract physiology after gastrectomy may affect appetite and energy balance. OBJECTIVE The objective of this study was to examine energy balance, appetite, and gastrointestinal transit in subjects with gastrectomy. DESIGN Seven subjects with total gastrectomy (TG) and 14 subjects with partial gastrectomy (PG), who were free from signs of recurrent disease, and 10 healthy control subjects were studied. Resting energy expenditure (REE) was measured by indirect calorimetry and compared with REE predicted by the Harris-Benedict equation (mREE/pREE%). Gastrointestinal transit was measured by scintigraphy. Habitual food intake was assessed, and appetite was measured during scintigraphy after ingestion of a test meal (361 kcal). RESULTS Body mass index was not different among the groups. mREE/pREE% was higher in patients with PG (P < 0.01) than in control subjects. The TG group showed higher energy intake (P < 0.05) than the PG group and control subjects. Gastric emptying was faster in the PG group than in control subjects, and gastrointestinal transit was accelerated in both PG and TG groups. An intense, precocious postprandial fullness and a relatively early recovery of hunger and prospective consumption sensations were seen in these patients. CONCLUSIONS Patients with PG or TG have higher than predicted energy expenditure, which in TG seems to be compensated for by increased energy intake. These patients have preserved postprandial appetite responses and precocious postprandial fullness, which seem to be associated with disturbances in gastrointestinal transit of the ingested meal and are likely to be independent of vagal fiber integrity or stomach-released ghrelin.

Abstract
Deficiencies of the major dietary sources of methyl groups, methionine and choline, lead to the formation of liver cancer in rodents. The most widely investigated hypothesis has been that dietary methyl insufficiency results in abnormal DNA methylation. Vitamin B12 and folate also play important roles in DNA methylation since these two coenzymes are required for the synthesis of methionine and S-adenosyl methionine, the common methyl donor required for the maintenance of methylation patterns in DNA. The aim of this study was to review the effects of methyl-deficient diets on DNA methylation and liver carcinogenesis in rats, and to evaluate the role of vitamin B12 status in defining carcinogenicity of a methyl-deficient diet. Several studies have shown that a methyl-deficient diet influences global DNA methylation. Evidence from in vivo studies has not clearly established a link between vitamin B12 and DNA methylation. We reported that vitamin B12 and low methionine synthase activity were the two determinants of DNA hypomethylation. Choline- or choline/methionine-deficient diets have been shown to cause hepatocellular carcinoma in 20-50% of animals after 12-24 months. In contrast, the effect of vitamin B12 withdrawal, in addition to choline, methionine and folate, induced hepatocellular carcinoma in less than 5% of rats.

Abstract
BACKGROUND Total gastrectomy often results in early satiety and loss of body weight. Serotonin inhibits food intake, and postprandial serotonin release is increased after total gastrectomy. Serotonin might contribute to early satiety and loss of body weight after total gastrectomy. METHODS AND MATERIALS Food intake and body weight were investigated with an automated recording system in gastrectomized rats 1-12 months postoperatively. Rats were treated with metergoline, a 5-hydroxytryptamine (5-HT)(1/2) receptor antagonist, two different 5-HT(3) receptor antagonists, a combination of metergoline and devazepide, a cholecystokinin (CCK) a receptor antagonist, or vehicle. In addition, metergoline or vehicle was applied continuously by an intraperitoneal osmotic minipump for 7, 28, or 84 days after total gastrectomy. RESULTS Metergoline treatment resulted in a dose-dependent increase in food intake in gastrectomized rats. 5-HT(3) receptor antagonist treatment had no effect, and devazepide in addition to metergoline did not further stimulate food intake. Metergoline increased food intake at 1, 3, and 6 months postoperatively by up to 45% (24-h cumulative food intake [FI], 6 months: vehicle 3.83 +/- 0.10, metergoline 5.52 +/- 0.15 g/100 g body weight (BW), P < 0.0001). Chronic metergoline treatment for 7, 28, or 84 days significantly increased food intake after total gastrectomy compared to vehicle treatment (FI 7 days: vehicle 30.83 +/- 0.71, metergoline 36.27 +/- 0.85 g/100 g BW; P < 0.0002; average weekly FI during 28 days; vehicle 31.23 +/- 0.22, metergoline 36.83 +/- 0.33 g/100 g BW, P < 0.0001; average weekly FI during 84 days: vehicle 33.02 +/- 0.59, metergoline 35.07 +/- 0.48 g/100g BW, P < 0.008), and there was a significant body weight increase compared to vehicle treatment (7 days: DeltaBW vehicle -0.7 +/- 1.2 g vs DeltaBW metergoline 9.0 +/- 2.1 g, P < 0.001; 28 days: DeltaBW vehicle 0.3 +/- 2.2 vs DeltaBW metergoline 13.0 +/- 2.3, P < 0.001; 84 days: DeltaBW vehicle 25.7 +/- 10.2 vs DeltaBW metergoline 49.5 +/- 7.2, P < 0.04). Treatment for 84 days resulted in a significant body weight gain, while vehicle treatment had no effect (vehicle: 438 +/- 11 g vs 464 +/- 12 g, P < 0.2, n.s.; metergoline: 448 +/- 9 g vs 498 +/- 10 g, P < 0.007). CONCLUSIONS Inhibition of food intake by serotonin might contribute to early satiety and loss of body weight after total gastrectomy.

Abstract
OBJECTIVE To investigate the central regulation of food intake by quantifying neuron activation of the nucleus of the solitary tract (NTS) after injection of cholecystokinin (CCK) or food intake in gastrectomized rats. SUMMARY BACKGROUND DATA Total gastrectomy is followed by early satiety, low calorie intake, and weight loss in the majority of patients. The etiology of these effects is unknown. Sixty percent to 70% of patients remain underweight after total gastrectomy, the weight loss averaging 25% of preoperative body weight. About two thirds of gastrectomized patients report early satiety, and about 60% do not reach the recommended daily calorie intake. The NTS is a brain stem center involved in the regulation of food intake; thus, the extent and pattern of neuronal activation provide information on the process involved in the initiation of satiation and the regulation of food intake. METHODS The authors investigated neuronal activation in the NTS using c-fos immunohistochemistry following CCK injection or food intake in healthy control rats, sham-operated control rats, age-matched control rats, weight-matched control rats, and vagotomized or gastrectomized rats. RESULTS Neuronal activation in the NTS after CCK injection was significantly decreased 21 days after total gastrectomy, but increased by up to 51% 3 months and by up to 102% 12 months after surgery compared to age-matched unoperated control rats. Neuronal activation in the NTS in response to feeding was markedly increased up to fivefold in gastrectomized rats. This increase was early in onset and sustained, and occurred despite significantly reduced food intake. Administration of MK329, a CCK-A receptor antagonist, significantly reduced the number of postprandially activated neurons in both gastrectomized and control rats. CONCLUSIONS The early postprandial activation of NTS neurons after total gastrectomy in rats may correspond to early satiety reported by patients, while the sustained activation of NTS neurons after a meal could contribute to a reduced daily calorie intake. These data suggest that a disturbed central regulation of food intake might contribute to early satiety, reduced food intake, and weight loss after total gastrectomy.

Abstract
After a brief account of the origins of laparoscopy and of its development into an interventional technique thanks to technical improvement, the author gives a dynamic state of the art in laparoscopic surgery, beginning with a description of his original classification method for laparoscopic procedures according to their level of use. Before tackling the highly controversial issue of laparoscopic surgery for cancer, he reviews in detail the various operations successfully performed by laparoscopy for the treatment of nonmalignant abdominal disorders and acute syndromes, all the while checking their results against those obtained with their open counterparts. As the various procedures are described, the interest of the laparoscopic approach becomes clearly visible, based on the excellent view of the operative field that allows diagnostic accuracy, thus avoiding unnecessary operations, and precise dissection with minimal damage. However, the laparoscopic approach is highly dependent on the surgeon's proficiency, itself depending on experience and therefore on the frequency of occurrence of the disorder, and on the progress in and availability of adequate equipments. The last chapter looks into the future of this ever-expanding approach and defines two great trends in its evolution, one accessible to the individual surgeon, the gradual adaptation of open procedures into laparoscopic ones, the other at the institutional level, in view of the huge financial support involved if high technologies are to be systematically integrated in this new surgery. What will the future be like?
