Filter by:In the study, the enhanced recovery after surgery (ERAS) program is applied to total pancreatectomy (TP) and low-risk pancreaticoduodenectomy (PD) patients identified by a small number of acinar cells in the cut edge of the pancreas. The research setting is randomized and controlled. All patients arriving at the Tampere University Hospital (TAUH) for PD or TP surgery are recruited into the study. Recruited patients are randomized to the ERAS protocol and to the standard protocol recovery program. The ERAS program differs from the normal care protocol preoperatively, intraoperatively and postoperatively as explained in the following section. In the ERAS protocol, both on the previous day of the surgery and on the following days, the patient is discussed with the patient about the benefits of the protocol used and the recovery program objectives. The purpose is to motivate and encourage the patient. On the day of surgery, the patient's intake of food and fluids is allowed to be closer to the surgery and the patient is also given a carbohydrate drink two hours before surgery. The nasogastric tube set at the beginning of surgery is removed at the end of the surgery and peripancreatic or perihepatic drains are not routinely placed. After surgery, drinking is allowed after four hours and the patient is encouraged to move as actively as possible in the bed. On the first and second postoperative day, the patient is allowed to enjoy normal food and drink according to his or her ability, and pancreatic capsules are given in the course of food. Additionally, the analgesic to be administered through the epidural cannula is dosed as far as possible to allow mobilization of the patient. The discussion on the benefits and recovery targets of the ERAS protocol are continued. On the third postoperative day, the epidural infusion is discontinued and the pain medication is moved to opioid-based pain management. This is continued until specific criteria for passing to the follow-up care are met. Typical complications (pancreatic fistula, delayed gastric emptying, postpancreatectomy hemorrhage) are registered during hospitalization and their severity ratings according to ISGPS, ISPGF and Clavien-Dindo classifications are also determined. Other variables registered are the number of intensive care days, situations requiring new surgeries, 30 and 90 day mortality, the completion time of the criteria for passing to follow up care, and the total length of hospitalization. In addition, the need for readmissions is registered. The implementation of the ERAS protocol is followed by a separate tracking template, in which the nurses record the progress of the goals specified in the protocol on a daily basis. The results of the study are analyzed with the intention-to-treat principle.
The incidence of oesophagogastric cancer has increased by 400% since the 1970s in Ireland and the United Kingdom. In addition, refinement of perioperative management and the now widespread use of multimodal protocols for patients with locally advanced disease have significantly improved outcomes for patients with oesophagogastric cancer treatable with curative intent. Despite significant advances in chemoradiotherapy, surgical resection remains the primary curative option. Unintentional weight loss and nutritional complications represent serious concerns for patients after radical resection, even among those who remain free from recurrent disease in the long-term. A study from the Swedish Esophageal and Cardia Cancer Registry reported a mean three year weight loss of 10.8% among disease-free patients, with 33.8% of this cohort demonstrating malnutrition at three years post-oesophagectomy. Mechanisms contributing to weight loss for disease-free patients after upper gastrointestinal surgery are poorly understood, however an association between increasing magnitude of weight loss and the presence of increased satiety is described. Our recent studies at SJH have demonstrated four fold elevated postprandial satiety gut hormone concentrations after oesophagectomy, compared with baseline preoperative values. Postprandial gut hormone levels correlate significantly with postprandial symptoms and altered appetite at 3 months postoperatively, and with body weight loss at 2 years postoperatively. However, the mechanism leading to exaggerated postprandial gut hormone production after upper gastrointestinal surgery is poorly understood, limiting targeted therapeutic options. In this study, we aim to characterise the role of altered nutrient transit and enteroendocrine cell function in the pathophysiology of excessive post-prandial gut hormone responses after upper gastrointestinal surgery. To do this, we will measure the gut hormone response to a standardised 400 kcal meal, as per previous studies, while concurrently assessing gastrointestinal transit time, and enteroendocrine cell morphology and function. In this way, we will determine whether the magnitude of the postprandial gut hormone response correlates with the rate of nutrient transit into the enteroendocrine L-cell rich small intestine, and whether enteroendocrine cell adaptation occurs after oesophagectomy. Furthermore, we have previously observed that gut hormone suppression using octreotide is associated with increased ad libitum among subjects after upper gastrointestinal cancer surgery (Elliott JA et al, Annals of Surgery, 2015). The mechanism of action of octreotide may relate to SSTR-5-mediated negative feedback to the enteroendocrine L-cell, but this medication may additionally reduce enteroendocrine L-cell responses through its inhibitory effect on gastrointestinal motility - reducing the rapidity with which nutrients are delivered to the small intestine - and small intestinal nutrient sensing via inhibition of the Na+-dependent glucose transporter SGLT-18-10. Through conduction of this double-blind, randomised, placebo-controlled crossover study, we aim to establish the mechanism of action of octreotide-mediated increased food intake in patients after gastrointestinal surgery. This may inform the design of future targeted interventions for this patient group.
The aim of the present prospective study was, first, to verify the correlation between biliary colonization and postoperative infectious complications, and secondarily to asses morbidity and mortality for patients who underwent pancreaticoduodenectomy. The hypothesis is that a proportion of post-operative infections after pancreaticoduodenectomy is due to bacteria that colonize the bile ducts during the preoperative period.
An open label, non-randomized, monocentric, interventional investigation in a cohort of adult critically ill patients
Children with a radionuclide gastric emptying test with abnormal results will undergo a second test with the addition of a weight adjusted dose of monosodium glutamate. The purpose of the study is to determine if a single dose of monosodium glutamate can shorten the gastric emptying time.
Surgical resection in periampullary cancer using pancreaticoduodenectomy is the most important modality in the treatment. In the past, pancreaticoduodenectomy was associated with high morbidity and mortality. However, with the advances in techniques, including perioperative patient management, development of antibiotics, diagnostic radiology, and interventional treatments, pancreaticoduodenectomy is now considered a safe and feasible operation. Postoperative complication rates are reported to be in 10 to 20% in experienced hospitals and operation related mortality is at about 1%. Therefore, surgical treatment for periampullary cancer is actively considered. However, postoperative complications, such as postoperative pancreatic fistula, (POPF) delayed gastric emptying, intraabdominal abscess, and postoperative bleeding, are still serious complications. Among these complications, delayed gastric emptying is considered less critical. However, delayed gastric emptying (DGE) can cause poor oral intake, which in turn, may lead to delay in recovery of postoperative nutritional state and in severe cases, requires insertion of levine tube and long-term fasting. There have been many hypotheses for cause of DGE after pancreaticoduodenectomy, but definite cause have not been discovered yet. With the introduction of pylorus-preserving pancreaticoduodenectomy (PPPD), incidences of DGE were initially reported to have increased. However, results of most randomized comparative studies had concluded that PPPD and PD have no significance in occurence of DGE. One hypothesis for cause of DGE we present here has to do with anatomic positioning of anastomosis site, especially pancreatojejunostomy (PJ) and duodenojejunostomy (DJ), after PPPD. Reconstruction after PPPD positions PJ and DJ close to each other. PJ site is often associated with one of postoperative complications, POPF. POPF may create inflammation around PJ site and pancreatitis, which may lead to severe adhesion around PJ as a secondary change. This adhesion and inflammation may cause DJ, which is located near PJ, to be pulled towards PJ site. When DJ is pulled towards PJ site, distal DJ site can become angulated and gastric contents may not beadle to pass easily. Gastric contents may be stagnated in stomach and thereby causing DGE. Therefore, in this study, we will fixate DJ on transverse colon using sutures, and prevent possibility of angulation of DJ. This additional procedure may reduce occurence of DGE.
The study investigates the effect of liquid food on the intake of energy and protein compared to solid food. One group will receive dietary counselling in fulfilling their need for energy and protein from liquid food and the other group from solid food.
Healthy volunteers will ingest a 13C-octaoate containing test meal and 13C in expiratory air will be followed. Normal values will be calculated data of these tests.
Delayed emptying of the gastric tube after esophagectomy is a frequent and durable problem. No treatment is currently available. It can be hypothesized that incomplete relaxation of the pyloric sphincter may be a significant contributing factor. Pneumatic dilatation may therefore be a potentially effective treatment.
The investigators plan to perform a prospective randomized, head-to-head trial to test the hypothesis that the addition of Braun enteroenterostomy to standard pancreaticoduodenectomy (PD) reconstruction can decrease the rates of Postoperative Pancreatic Fistula (POPF) and/or Delayed Gastric Emptying (DGE).
