Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction, adhesive ileus has never been reported to complicate this - in any sense rare - condition. We present a unique case of a patient with myasthenia gravis, free of thymus neoplasia, who was submitted to emergency surgery due to the presence of extended adhesive ileus as a complication of chronic intestinal functional obstruction.

Cholesterol crystal embolization (CCE) is a rare systemic embolism caused by formation of cholesterol crystals from atherosclerotic plaques. CCE usually occurs during vascular manipulation, such as vascular surgery or endovascular catheter manipulation, or due to anticoagulation or thrombolytic therapy. We report a rare case of intestinal obstruction caused by spontaneous CCE. An 81-year-old man with a history of hypertension was admitted for complaints of abdominal pain, bloating, and anorexia persisting for 4 mo. An abdominal computed tomography revealed intestinal ileus. His symptoms were immediately relieved by an ileus tube insertion, and he was discharged 6 d later. However, these symptoms immediately reappeared and persisted, and partial resection of the small intestine was performed. A histopathological examination indicated that small intestine obstruction was caused by CCE. At the 12-mo follow-up, the patient showed no evidence of CCE recurrence. Thus, in cases of intestinal obstruction, CCE should also be considered.

Although adhesions account for more than 70% of small bowel obstruction (SBO), they are thought to be less likely aetiologies in patients without previous abdominal surgery. Expedient surgery has historically been advocated as prudent management in these patients. Emerging evidence appears to challenge such a dogmatic approach. A retrospective analysis was performed in all SBO patients with a virgin abdomen admitted between January 2012 and August 2014. Patients with obstruction secondary to abdominal wall hernias were excluded. Patient demographics, clinical presentation, management strategy and pathology involved were reviewed. A total of 72 patients were included in the study. The majority of patients were males (66.7%), with a median age of 58 years (range: 23-101). Abdominal pain (97%) and vomiting (86%) were the most common presentations while abdominal distention (60%) and constipation (25%) were reported less frequently. Adhesions accounted for the underlying cause in 44 (62%) patients. Other aetiologies included gallstone ileus (n = 5), phytobezoar (n = 5), intussusception (n = 4), internal herniation (n = 4), newly diagnosed small bowel tumour (n = 3), mesenteric volvulus (n = 3), stricture (n = 3) and Meckel's diverticulum (n = 1). Twenty-nine (40%) patients were successfully managed conservatively while the remaining 43 (60%) underwent surgery. The intraoperative findings were in concordance with the preoperative computed tomography scan in 76% of cases. Adhesions remain prevalent despite the absence of previous abdominal surgery. Non-operative management is feasible for SBO in a virgin abdomen. Computed tomography scan can be a useful adjunct in discerning patients who may be treated non-operatively by elucidating the underlying cause of obstruction. © 2016 Royal Australasian College of Surgeons.

Courvoisier's gallbladder: law or sign?

PubMed

Fitzgerald, J Edward F; White, Matthew J; Lobo, Dileep N

2009-04-01

Variously described as Courvoisier's law, sign, or even gallbladder, this eponymous "law" has been taught to medical students since the publication of Courvoisier's treatise in 1890. We reviewed Courvoisier's original "law," the modern misconceptions surrounding it, and the contemporary evidence supporting and explaining his observations. Courvoisier never stated a "law" in the context of a jaundiced patient with a palpable gallbladder. He described 187 cases of common bile duct obstruction, observing that gallbladder dilatation seldom occurred with stone obstruction of the bile duct. The classic explanation for Courvoisier's finding is based on the underlying pathologic process. With the presence of gallstones come repeated episodes of infection and subsequent fibrosis of the gallbladder. In the event that a gallstone causes the obstruction, the gallbladder is shrunken owing to fibrosis and is unlikely to be distensible and, hence, palpable. With other causes of obstruction, the gallbladder distends as a result of the back-pressure from obstructed bile flow. However, recent experiments show that gallbladders are equally distensible in vitro, irrespective of the pathology, suggesting that chronicity of the obstruction is the key. Chronically elevated intraductal pressures are more likely to develop with malignant obstruction owing to the progressive nature of the disease. Gallstones cause obstruction in an intermittent fashion, which is generally not consistent enough to produce such a chronic rise in pressure. We hope that reminding clinicians of Courvoisier's actual observations will reestablish the usefulness of this clinical sign in the way he intended.

Jejuno-jejunal intussusception in a guinea pig (Cavia porcellus)

Fetzer, Tara J.; Mans, Christoph

2017-01-01

An approximately four-year-old male castrated guinea pig (Cavia porcellus) was presented for painful defecation with a 24-hour history of hyporexia and intermittent episodes of rolling behavior. Upon presentation the patient was quiet, alert, and responsive, and mildly hypothermic. Abdominal palpation revealed an approximately 2-cm long oblong mass within the caudal abdomen. Abdominal radiographs revealed gastric dilation without volvulus and a peritoneal mass effect. The patient was euthanized following gastric reflux of brown malodorous fluid from his nares and oral cavity. A necropsy was performed and revealed a jejuno-jejunal intussusception causing mechanical gastrointestinal ileus, and gastric dilatation without volvulus. While non-obstructive gastrointestinal stasis is common and obstructive ileus is uncommon in guinea pigs, this report shows that intestinal intussusception is a differential in guinea pigs with ileus and gastric dilatation.

Our aim was to investigate the calcium content of different gallstone compositions and the pathogenic mechanisms of calcium carbonate gallstones. Between August 2001 and July 2007, gallstones from 481 patients, including 68 calcium carbonate gallstones, were analyzed for total calcium content. Gallbladder bile samples from 33 cases and six controls were analyzed for pH, carbonate anion level, free-ionized calcium concentration and saturation index for calcium carbonate. Total calcium content averaged 75.6 %, 11.8 %, and 4.2 % for calcium carbonate, calcium bilirubinate and cholesterol gallstones. In 29.4 % of patients, chronic and/or intermittent cystic duct obstructions were caused by polypoid lesions in the neck region and 70.6 % were caused by stones. A total of 82 % of patients had chronic low-grade inflammation of the gallbladder wall and 18.0 % had acute inflammatory exacerbations. In the bile, we found the mean pH, mean carbonate anion, free-ionized calcium concentrations, and mean saturation index for calcium carbonate to be elevated in comparison to controls. From our study, we found chronic and/or intermittent cystic duct obstructions and low-grade GB wall inflammation lead to GB epithelium hydrogen secretion dysfunction. Increased calcium ion efflux into the GB lumen combined with increased carbonate anion presence increases SI_CaCO(3) from 1 to 22.4. Thus, in an alkaline milieu with pH 7.8, calcium carbonate begins to aggregate and precipitate. Copyright © 2012. Published by Elsevier B.V.

The aim of this study was to evaluate the effects of a traditional Chinese herbal medicine, dai-kenchu-to (DKT), on obstructive bowel diseases in children. We have treated 46 pediatric patients with various obstructive bowel diseases with DKT: six patients with postoperative ileus, 12 with large abdominal surgery (including three neonates), one with ano-rectal anomaly, three with Hirschsprung's disease, two with functional bowel obstructions, one with SMA syndrome, and 21 patients with chronic constipation. DKT (0.1-0.15 g/kg) was mixed with 5-10 ml of warm water, and was given orally two to three times a day. DKT was effective for 39 patients (85%) and their clinical symptoms improved. DKT was ineffective in seven patients: two with postoperative ileus, two with Hirschsprung's disease, and three with chronic constipation. DKT had mild but significant effects for various obstructive bowel diseases in children, while no side effects were encountered. Our current strategy for pediatric patients with obstructive bowel disease is to use DKT first and then test its efficacy. If DKT is effective, the regimen is continued. However, in cases where DKT is not effective, we will consider laparotomy or will further investigate the illness.

Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon) is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

The definition of ileus has undergone deep changes over the last three millennia. The term ileus was originally used in Classic Greece to describe a common cause of intestinal obstruction, and subsequently the Romans would often translate it into the Latin word volvulus. During the Renaissance, ileus, volvulus and intussusception became synonymous with a vulgar term--Miserere Mei or Miserere colic--whose origin and evolution are still much of a mystery. This paper provides some historical investigation on the Miserere Mei or Miserere colic, with the aim of discussing its evolution within medical literature during the 17th and 18th centuries.

2007-03-01

In contrast to adults, calcium carbonate gallstones are relatively common in children. Their pathogenesis is poorly understood. Cystic duct obstruction promotes calcium carbonate formation in bile and increases gallbladder mucin production. We tested the hypothesis that mucin producing epithelial cells would be increased in gallbladders of children with calcium carbonate gallstones. Archival gallbladder specimens from 20 consecutive children who had undergone elective cholecystectomy for cholelithiasis were examined. In each case, gallstone composition was determined by Fourier transform infrared microspectroscopy. Gallbladder specimens from six children who had undergone cholecystectomy for conditions other than cholelithiasis during the same period were used as controls. Multiple sections were examined in a blinded fashion and scored semiquantitatively for mucin production using two stains (alcian blue and periodic acid-Schiff). Increased mucin staining was observed in 50% or more epithelial cells in five gallbladder specimens from seven children with calcium carbonate stones, compared to 5 of 13 with other stone types (P = 0.17) and none of the control gallbladders (P = 0.02). Gallbladders containing calcium carbonate stones were significantly more likely than those containing other stone types or controls to contain epithelial cells with the greatest mucin content (P = 0.03). Gallbladders containing calcium carbonate stones were also more likely to show the ulcer-associated cell lineage. These results demonstrate an increase in mucin producing epithelial cells in gallbladders from children containing calcium carbonate stones. This supports the hypothesis that cystic duct obstruction leading to increased gallbladder mucin production may play a role in the development of calcium carbonate gallstones in children.

Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

Stone formation within the intestinal lumen is called enterolith. This stone can encroach into the lumen causing obstruction and surgical emergency. Jejunal obstruction by an enterolith is a very rare entity and often missed preoperatively. To our knowledge, most cases of jejunal obstruction, secondary to stone, were associated with biliary disease (cholecystoenteric fistula), bezoar, jejunal diverticulosis, or foreign body. Hereby we present a rare case report of small bowel obstruction in an elderly man who was diagnosed lately to have primary proximal jejunal obstruction by an enterolith without evidence of a cholecystoenteric fistula or jejunal diverticulosis. This patient underwent laparotomy, enterotomy with stone extraction, and subsequent primary repair of the bowel.

Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders. After birth, 10-15% of newborns with CF may develop intestinal obstruction within a few days of birth because of meconial ileus. 1 This obstruction is a result of dehydrated thickened meconium obstructing the intestinal lumen. We report two cases of fetuses with prenatal diagnosis of segmental volvulus in whom CF was diagnosed. 2016 BMJ Publishing Group Ltd.

Meconium ileus, intestinal obstruction in the newborn, is caused in most cases by CFTR mutations modulated by yet-unidentified modifier genes. We now show that in two unrelated consanguineous Bedouin kindreds, an autosomal-recessive phenotype of meconium ileus that is not associated with cystic fibrosis (CF) is caused by different homozygous mutations in GUCY2C, leading to a dramatic reduction or fully abrogating the enzymatic activity of the encoded guanlyl cyclase 2C. GUCY2C is a transmembrane receptor whose extracellular domain is activated by either the endogenous ligands, guanylin and related peptide uroguanylin, or by an external ligand, Escherichia coli (E. coli) heat-stable enterotoxin STa. GUCY2C is expressed in the human intestine, and the encoded protein activates the CFTR protein through local generation of cGMP. Thus, GUCY2C is a likely candidate modifier of the meconium ileus phenotype in CF. Because GUCY2C heterozygous and homozygous mutant mice are resistant to E. coli STa enterotoxin-induced diarrhea, it is plausible that GUCY2C mutations in the desert-dwelling Bedouin kindred are of selective advantage.

The outcome of unretrieved gallstones in the peritoneal cavity during laparoscopic cholecystectomy. A prospective analysis.

1999-09-01

Gallbladder perforation during laparoscopic cholecystectomy (LC) with spillage of bile and gallstones occurs in a substantial number of patients (up to 40%). Most surgeons believe that free intraperitoneal stones are not a justification for conversion to laparotomy even if a large number of stones are left in situ. There are, however, a number of reports demonstrating that, on occasion, these unretrieved gallstones may cause infection or abscess, inflammation, fibrosis, adhesions, cutaneous sinuses, small bowel obstruction, or generalized septicemia. The aim of this study was to determine the outcome of unretrieved gallstones in the peritoneal cavity after gallbladder perforation during LC. In a 7-year period between 1989 and 1996, prospective data were maintained on 856 patients who underwent LCs by a single surgeon (R. J.F.). Of the 856 patients, 165 (16%) had gallbladder perforations resulting in lost gallstones in the peritoneal cavity. A concerted attempt was made to remove the lost stones using a variety of extraction devices. Of these 165 patients, 106 (64%) were available for follow-up through mail (76%) and by telephone (24%). The mean age of these patients was 64.9 years (range, 18 to 98 years), and the mean follow-up was 44.8 months (range 4.9 to 92.3 months). Of the 106 patients with unretrieved gallstones, we identified four patients with short-term complications and one patient with a long-term complication. The first patient with a short-term complication had pyrexia for 10 days postoperatively. Diagnostic evaluation, which included computed tomography (CT) scan, failed to reveal any abnormality. The patient was treated conservatively with a course of oral antibiotics. In the second patient, cellulitis developed at a drain site after its removal, which resolved with oral antibiotics. The third patient acquired an umbilical wound abscess, which drained spontaneously, requiring no treatment. A sterile subphrenic collection developed in the fourth patient 1 month postoperatively, which was treated with percutaneous drainage under CT guidance. The only long-term complication was spontaneous erosion of a gallstone from the back of a patient with a questionable history of inflammatory bowel disease 8 months postoperatively. All of the patients made complete recoveries. In most patients, unretrieved gallstones are of no consequence, but complications occur occasionally. It is therefore advisable to retrieve as many gallstones as possible during LC short of converting to a laparotomy.

The majority of bowel obstructions in extremely low birth weight (ELBW) neonates are meconium-related ileus (MRI). ELBW neonates with bowel obstruction may recover by conservative treatment, but some do not. Considering the high surgical morbidity rates, unnecessary surgery should be avoided. We sought to identify a reasonable treatment strategy under these conditions. ELBW neonates who started to have bowel obstruction with an unclear cause within 14 days of age were enrolled. The study period was from January 2009 to August 2011. The enrolled patients had daily Gastrografin(®) enemas until 14 days of age or until the obstruction resolved. If the obstruction lasted beyond around 14 days of age, the patient underwent surgical intervention. The clinical data of the patients were collected and analyzed. Fourteen patients were enrolled. Twelve patients had MRI, which resolved within 14 days without surgery. Two patients with persistent obstruction underwent surgery, and they were found to have Hirschsprung's disease and ileal volvulus, respectively. For ELBW neonates with bowel obstruction of unclear etiology, the early and frequent administration of a Gastrografin(®) enema is reasonable. Surgery should be considered if the obstruction lasts beyond approximately 14 days after birth.

The percutaneous transhepatic cholangiography was the diagnostic method that suggested a double illness of the biliary system. The surgery and the pathology certificated the diagnosis. The correct treatment once confirmed the obstructive trial, must be: the extraction of the biliary gallstones and the bile-digestive derivation (preferently the hepatic-jejunum anastomosis in Y of Roux).

Our center previously reported its experience with pediatric gallbladder disease and cholecystectomies from 1980 to 1996. We aimed to determine the current clinical characteristics and risk factors for symptomatic pediatric gallbladder disease and cholecystectomies and compare these findings with our historical series. Retrospective, cross-sectional study of children, 0 to 18 years of age, who underwent a cholecystectomy from January 2005 to October 2008. We evaluated 404 patients: 73% girls; 39% Hispanic and 35% white. The mean age was 13.10 ± 0.91 years. The primary indications for surgery in patients 3 years or older were symptomatic cholelithiasis (53%), obstructive disease (28%), and biliary dyskinesia (16%). The median BMI percentile was 89%; 39% were classified as obese. Of the patients with nonhemolytic gallstone disease, 35% were obese and 18% were severely obese; BMI percentile was 99% or higher. Gallstone disease was associated with hemolytic disease in 23% (73/324) of patients and with obesity in 39% (126/324). Logistic regression demonstrated older age (P = .019) and Hispanic ethnicity (P < .0001) as independent risk factors for nonhemolytic gallstone disease. Compared with our historical series, children undergoing cholecystectomy are more likely to be Hispanic (P = .003) and severely obese (P < .0279). Obesity and Hispanic ethnicity are strongly correlated with symptomatic pediatric gallbladder disease. In comparison with our historical series, hemolytic disease is no longer the predominant risk factor for symptomatic gallstone disease in children.

Despite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile. We describe the important factors in bile synthesis and secretion that affect the composition of bile and consequently its liquid state. Within this biochemical background lies the foundation for understanding the clinical and sonographic manifestation of cholelithiasis, including the pathophysiology of cholesterol crystallization, gallbladder sludge, and gallstones. There is a brief discussion of the clinical manifestations of inflammatory and obstructive cholestasis and the impact on bile metabolism and subsequently on liver function tests. Despite being the key modality in diagnosing cholelithiasis, ultrasound has a limited role in the characterization of stone composition.

Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract (GIT). Importance of GISTs is increasing while surgeons are facing with more frequent either in emergency setting of elective cases. Delineating the presentation and management of emergency GIST is important. From 2005 to 2014, emergency cases with final diagnosis of GIST were examined retrospectively. Total of 13 operated cases were evaluated by patients characteristics, clinical presentation, operational findings and postoperative prognosis. There were 9 male and 4 female with the mean age of 48.15 years. The most frequent presentations are ileus and GIT hemorrhage both covering the 84% of patients. Small bowel was the dominating site with ileus. Stomach was the second frequent site of the disease with the finding of hemorrhage. Emergency patients are more likely to come with small bowel GIST and obstruction symptoms. Hemorrhage is the most frequent symptom for emergency GIST of stomach and duodenum.

[Influence of early kinesitherapy on rehabilitation postoperative recovery in case of low extremity operations].

Arteriosclerosis is a disease effecting large elastic, elastic muscular and large muscular arteries. The primary pathological changes are found inside the arteries. Salient feature is atherosclerotic plaque. The main purpose of this paper is to determine whether early kinesitherapy with verticalization and mobilization can give better rehabilitation results with patients after lower extremities operation, in comparison to patients which were not mobilized early in this stage. In this paper we have analyzed two groups of 40 patients that were operatively treated for circulation obstruction to lower extremities. The first, tested group was treated with early kinesiotherapy with early verticalization and mobilization. The second, controlled group was treated with kinesitherapy in bed. All the patients were analyzed according to their gender, age, primary diagnosis, postoperative complications, as well as capabilities for everyday activities. For the evaluation of the everyday life activities we used the Barthel index at hospital admission and discharge. Both groups of patients were equable in gender and age. The most common age group within the tested groups was between 61-70 for males and 51-60 for woman.The most common type of obstruction in both groups was occlusion of femoral artery. The complications which occurred among the tested patients were thrombosis, ileus and contracture in 7.5% of cases, while 85% of patients did not have any complications. Within the controlled group, decubitus occurred in 7.5% of cases, as well as gangrene and ileus. Ulcus occurred in 5% of patients, thrombosis in 10%, and contracture in 4% of cases. 40% of patients in this group were without complications. Based on the results stated above we can conclude that early kinesitherapy with verticalization and mobilization of patients in postoperative phase after the treatment of lower extremities obstruction, have shown much better results in comparison to the patients which were only treated with kinesitherapy in bed. This method of treatment should be included as protocol treatment for all patients after surgical treatment of lower extremities obstruction.

''Sandwich'' treatment for diospyrobezoar intestinal obstruction: A case report

Intestinal obstruction is a common clinical entity encountered in surgical practice. The objective of this report is to corroborate an atypical scenario of intestinal obstruction in a Chinese patient and to focus on the diagnosis and treatment. A 27-year-old male presented with a history of gastric pain combined with nausea and abdominal distension that had been present for 5 d. The presence of a foreign body was detected by computed tomography and observed as an abnormal density within the stomach. A diospyrobezoar was revealed during gastroscopy, the extraction of which was prevented due to its size and firmness. An endoscopic holmium laser joined with a snare was used to fragment the obstruction, which was followed by management with a conservative “sandwich” treatment strategy involving intestinal decompression with an ileus tube and Coca-Cola lavage between endoscopic lithotripsy fragmentation procedures. This strategy resulted in the successful removal of the diospyrobezoar along with multiple small bowel obstructions. The patient was discharged after abatement of symptoms. The case presented here demonstrates the implementation of a conservative, yet successful, treatment as an alternative to conventional surgical removal of intestinal obstructions. PMID:25561823

We report the first case of Mirizzi syndrome in a patient who presented with biliary obstruction caused by pure calcium carbonate stones. A 61 years old male with history of portal vein thrombosis presented with rash, nausea and jaundice. An ultrasound of biliary tree showed gallstones with dilatation of hepatic duct and intrahepatic biliary tree. There was suspicion of a stone in proximal CBD. CT scan showed an opaque gallbladder with dense radio-opaque material in its lumen. An ERCP was then performed revealing external common hepatic duct obstruction at the neck of the gallbladder. A plastic biliary stent was placed across the obstruction, followed by a cholecystectomy. Resected gallbladder specimen revealed thick whitish paste like material, and formed stones filling the gallbladder lumen. Laboratory testing showed this material to be composed of 100% calcium carbonate crystals.

Postoperative ileus (POI) after colorectal surgery is associated with prolonged hospital stay and increased costs. The aim of this study is to investigate pre-, intra-, and postoperative risk factors associated with the development of POI in patients undergoing laparoscopic partial colectomy. Patients operated between 2004 and 2008 were retrospectively identified from a prospectively maintained database, and clinical, metabolic, and pharmacologic data were obtained. Postoperative ileus was defined as the absence of bowel function for 5 or more days or the need for reinsertion of a nasogastric tube after starting oral diet in the absence of mechanical obstruction. Associations between likelihood of POI and study variables were assessed univariably by using χ tests, Fisher exact tests, and logistic regression models. A scoring system for prediction of POI was constructed by using a multivariable logistic regression model based on forward stepwise selection of preoperative factors. A total of 413 patients (mean age, 58 years; 53.5% women) were included, and 42 (10.2%) of them developed POI. Preoperative albumin, postoperative deep-vein thrombosis, and electrolyte levels were associated with POI. Age, previous abdominal surgery, and chronic preoperative use of narcotics were independently correlated with POI on multivariate analysis, which allowed the creation of a predictive score. Patients with a score of 2 or higher had an 18.3% risk of POI (P < 0.001). Postoperative ileus after laparoscopic partial colectomy is associated with specific preoperative and postoperative factors. The likelihood of POI can be predicted by using a preoperative scoring system. Addressing the postoperative factors may be expected to reduce the incidence of this common complication in high-risk patients.

The "gastrografin challenge" has been used for decades in the evaluation of small bowel obstruction (SBO). This type of study involves enteric administration of a water-soluble contrast followed by serial abdominal radiographs. While its diagnostic role is well established, its therapeutic role remains controversial. Following an algorithm for gastrografin challenge cases can help with interpretation. An understanding of the appearance of diluted contrast in the small bowel, the concentrating effect of contrast in the colon, and knowledge of surgical history and anatomy is paramount for diagnosis. In this article, we review the approach to acute SBO and the use of gastrografin along with reviewing image interpretation of cases of partial and complete SBO. Gastrografin use in adynamic ileus along with other potential future uses is also discussed.

[The Management of Common Bile Duct Stones].

PubMed

Park, Chang Hwan

2018-05-25

Common bile duct (CBD) stone is a relatively frequent disorder with a prevalence of 10-20% in patients with gallstones. This is also associated with serious complications, including obstructive jaundice, acute suppurative cholangitis, and acute pancreatitis. Early diagnosis and prompt treatment is the most important for managing CBD stones. According to a recent meta-analysis, endoscopic ultrasonography and magnetic resonance cholangiopancreatography have high sensitivity, specificity, and accuracy for the diagnosis of CBD stones. Endoscopic ultrasonography, in particular, has been reported to have higher sensitivity between them. A suggested management algorithm for patients with symptomatic gallstones is based on whether they are at low, intermediate, or high probability of CBD stones. Single-stage laparoscopic CBD exploration and cholecystectomy is superior to endoscopic retrograde cholangiopancreatography (ERCP) plus laparoscopic cholecystectomy with respect to technical success and shorter hospital stay in high risk patients with gallstones and CBD stones, where expertise, operative time, and instruments are available. ERCP plus laparoscopic cholecystectomy is usually performed to treat patients with CBD stones and gallstones in many institutions. Patients at intermediate probability of CBD stones after initial evaluation benefit from additional biliary imaging. Patients with a low probability of CBD stones should undergo cholecystectomy without further evaluation. Endoscopic sphincterotomy and endoscopic papillary balloon dilation in ERCP are the primary methods for dilating the papilla of Vater for endoscopic removal of CBD stones. Endoscopic papillary large balloon dilation is now increasingly performed due to the usefulness in the management of giant or difficult CBD stones. Scheduled repeated ERCP may be considered in patients with high risk of recurrent CBD stones.

We report a case of a 64-year-old lady who developed clinical features of Wernicke-Korsakoff syndrome following a laparotomy for small bowel obstruction. Following the operation she developed paralytic ileus and required total parenteral nutrition for one month. A suspected history of average 40 units of weekly alcohol consumption prior to the operation could not be confirmed and the patient did not show any sign of alcohol dependence. Within a few months of treatment with a daily oral dose of thiamine 200 mgs supplemented by multivitamins the patient showed subjective evidence of improvement in confusion, confabulation, and anterograde amnesia, although objective tests showed residual deficits in many areas of cognitive functioning, including immediate and delayed recall of verbal and non-verbal materials, planning and switching of attention.

An 85-year-old woman with no history of abdominal surgery complained of abdominal pain and vomiting and was referred to us with a diagnosis of intestinal obstruction a few days later. Upon admission to our facility, she presented with marked abdominal swelling and prominent kyphosis. Because of the kyphosis, most of the dilated bowel was compressing her thoracic cavity. No obvious strangulation or free air was observed via abdominal computed tomography imaging. We attempted decompression using a nasogastric tube, but the symptoms persisted. Surgery was performed 2 days after admission. The origin of the obstruction was a compression of the ileocecal region by the costal arch. The bowel was discolored, and thus surgically excised. There were no major postsurgical complications other than a mild wound infection. Until now, there have been no reports of advanced kyphosis inducing ileus, but there are concerns of an increase in similar cases as society continues to age. PMID:23971780

Imaging by ultrasound has dramatically changed the investigation and management of many clinical problems. It is useful in many different parts of the body. In this brief discussion, the following topics are considered: hepatic lesions, bleeding in early pregnancy, gynecological pathology (adnexal lesions), aortic aneurysms, thyroid nodules and scrotal masses. The usefulness of duplex carotid sonography, which combines ultrasonic imaging and Doppler studies, is also discussed. Other topics (gallstones, biliary obstruction, renal calculi, hydronephrosis) are discussed in the appropriate sections. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:21267202

The application value of small intestine decompression combined with oral feeding in the middle and late period of malignant small bowel obstruction was examined. A total of 22 patients with advanced malignant small bowel obstruction were included in the present study. An ileus tube was inserted via the nose under fluoroscopy into the obstructed small intestine of each patient. At the same time, the insertion depth the of the catheter was adjusted. When the catheter was blocked, small bowel selective angiography was performed to determine the location and cause of the obstruction and the extent of the obstruction, and to determine the length of the small intestine in the site of obstruction, and to select the variety and tolerance of enteral nutrition. We observed the decompression tube flow and ease of intestinal obstruction. In total, 20 patients were treated with oral enteral nutrition after abdominal distension, and 22 cases were treated by the nose to observe the drainage and the relief of intestinal obstruction. The distal end of the catheter was placed in a predetermined position. The symptoms of intestinal obstruction were relieved 1-4 days after decompression. The 22 patients with selective angiography of the small intestine showed positive X-ray signs: 18 patients with oral enteral nutrition therapy had improved the nutritional situation 2 weeks later. In 12 cases, where there was anal defecation exhaust, 2 had transient removal of intestinal obstruction catheter. In conclusion, this comprehensive treatment based on small intestine decompression combined with enteral nutrition is expected to become a new therapeutic approach and method for the treatment of patients with advanced tumor small bowel obstruction.

A 60-year-old woman with a history of distal gastrectomy for gastric cancer presented with a chief complaint of epigastric pain. Duodenal ileus due to the migration of a gastric bezoar was diagnosed, and she was hospitalized. We performed endoscopic lithotripsy and injection of cola, but the bezoar migrated toward the anus. Her abdominal pain worsened the following day, and she was diagnosed with ileus induced by the gastric bezoar. After decompression with an ileus tube, 1000ml/day of cola was injected via the ileus tube, and the ileus resolved on the 5th day of therapy. Based on this experience, we believe that dissolution therapy with cola via an ileus tube is effective in the treatment of bezoar-induced small bowel ileus.

Gallstones are usually recognized on MRI as filling defects of hypointensity. However, they sometimes may appear as hyperintensities on T1-weighted imaging. This study investigated how gallstones appear on MRI and how their appearance influences the detection of gallstones. Gallstones from 24 patients who had MRI performed before the removal of the gallstones were collected for study. The gallstones were classified either as cholesterol gallstone (n = 4) or as pigment gallstone (n = 20) according to their gross appearance and based on analysis by Fourier transform infrared spectroscopy. MRI included three sequences: single-shot fast spin-echo T2-weighted imaging, 3D fast spoiled gradient-echo T1-weighted imaging, and in-phase fast spoiled gradient-echo T1-weighted imaging. The signal intensity and the detection rate of gallstones on MRI were further correlated with the character of the gallstones. On T1-weighted 3D fast spoiled gradient-echo images, most of the pigment gallstones (18/20) were hyperintense and all the cholesterol gallstones (4/4) were hypointense. The mean ratio of the signal intensity of gallstone to bile was (+/- standard deviation) 3.36 +/- 1.88 for pigment gallstone and 0.24 +/- 0.10 for cholesterol gallstone on the 3D fast spoiled gradient-echo sequence (p < 0.001). Combining the 3D fast spoiled gradient-echo and single-shot fast spin-echo sequences achieved the highest gallstone detection rate (96.4%). Based on the differences of signal intensity of gallstones, the 3D fast spoiled gradient-echo T1-weighted imaging was able to diagnose the composition of gallstones. Adding the 3D fast spoiled gradient-echo imaging to the single-shot fast spin-echo T2-weighted sequence can further improve the detection rate of gallstones.

Gallstones are one of the most common diseases worldwide. Recently, the incidence of gallstones has increased and the pattern of gallstones has changed in Korea. Laparoscopic cholecystectomy is the standard treatment for symptomatic gallstones. Expectant management is considered the most appropriate choice in patients with asymptomatic gallstones. The dissolution of cholesterol gallstones by oral bile acid, such as ursodeoxycholic acid, can be considered in selected patients with gallstones. Although the advent of laparoscopic cholecystectomy has moved interest away from the pharmacologic treatment of gallstones, several promising agents related to various mechanisms are under investigation.

Endoscopic dilatation is a treatment option for patients with Crohns disease suffering from stenosis in relation to an ileorectal anastomosis. We present a case of a patient with Crohns disease who was admitted with acute obstructive symptoms due to a stensosis of the ileorectal anastomosis. The patient was septic. We performed a successful endoscopic dilatation in the acute phase and the patient was discharged few days after an uneventful recovery. Endoscopic dilatation of an ileorectal anastomsis in patients with Crohns disease is a treatment option in the acute setting when performed by experienced endoscopists.

Gallstone disease is an important, costly health-care problem in Western societies. It is still unclear whether hepatic lipid regulatory enzymes play primary or secondary roles in gallstone formation. In this study, the aim was to investigate whether the synthesis of bile acids and cholesterol is increased in gallstone disease and to test whether such a metabolic change, if present, might occur before gallstone formation. A total of 125 Chilean Hispanic women (80 without gallstones and 45 with gallstones) matched for age and body mass index were investigated, along with 40 Chilean Mapuche Indian women (20 without gallstones and 20 with gallstones), a population group in which the prevalence for gallstone disease is very high. Fasting blood plasma samples were assayed for 7 alpha-hydroxy-4-cholesten-3-one and lathosterol, 2 strong indicators for hepatic bile acid and body cholesterol synthesis, respectively. Plasma 7 alpha-hydroxy-4-cholesten-3-one levels, corrected for plasma cholesterol, were significantly increased by 50% in Hispanic women with gallstones as compared with gallstone-free Hispanics (P < 0.006). As compared with Hispanic women without gallstones, plasma 7 alpha-hydroxy-4-cholesten-3-one levels were increased by > or =100% (P < 0.002) in Mapuche Indian women, independently of whether gallstones were present. Plasma lathosterol, corrected for plasma cholesterol, was significantly increased by 22% in Hispanic women with gallstones and in Mapuche Indian women compared with Hispanic women. The results indicate that the synthesis of bile acids and cholesterol is induced in gallstone disease and precedes gallstone development. These inductions presumably occur as a response to an increased intestinal loss of bile acids.

The prevalence of cholesterol gallstones has increased in recent years. Bacterial infection correlates with the formation of gallstones. We studied the composition and function of bacterial communities in cholesterol gallstones and bile from 22 cholesterol gallstone patients using culture-dependent and culture-independent methods. Altogether fourteen and eight bacterial genera were detected in cholesterol gallstones and bile, respectively. Pseudomonas spp. were the dominant bacteria in both cholesterol gallstones and bile. As judged by diversity indices, hierarchical clustering and principal component analysis, the bacterial communities in gallstones were different from those in bile. The gallstone microbiome was considered more stable than that of bile. The different microbial communities may be partially explained by differences in their habitats. We found that 30% of the culturable strains from cholesterol gallstones secreted β-glucuronidase and phospholipase A2. Pseudomonas aeruginosa strains showed the highest β-glucuronidase activity and produced the highest concentration of phospholipase A2, indicating that Ps. aeruginosa may be a major agent in the formation of cholesterol gallstones.

Mechanical property studies of human gallstones.

1990-08-01

The recent development of gallstone fragmentation methods has increased the significance of the study of the mechanical properties of human gallstones. In the present work, fracture strength data and microhardness values of gallstones of various chemical compositions are presented as tested in both dry and simulated bile environments. Generally, both gallstone hardness and fracture strength values were significantly less than kidney stone values found in previous studies. However, a single calcium carbonate stone was found to have an outer shell hardness exceeding those values found for kidney stones. Diametral compression measurements in simulated bile conclusively demonstrated low gallstone fracture strength as well as brittle fracture in the stones tested. Based on the results of this study, one may conclude that the wide range of gallstone microhardnesses found may explain the reported difficulties previous investigators have experienced using various fragmentation techniques on specific gallstones. Moreover, gallstone mechanical properties may be relatively sensitive to bile-environment composition.

Objective: Neostigmine is one of the treatment options for colonic pseudo-obstruction in the medical patient. However, experience in using neostigmine for this indication in burn patients has not been reported in the literature. We will present a case of a woman who developed colonic pseudo-obstruction during her hospital stay. When conservative management failed, neostigmine was administered with no adverse effects and resolution of the pseudo-obstruction. We will review the literature regarding the pathophysiology and treatment options for acute colonic pseudo-obstruction in burn patients. Methods: A 27-year-old woman with 35% total body surface area deep-partial and full-thickness flame burns. On hospital day 17, she developed a nonobstructive ileus. She failed conservative medical therapy. After consultation with colleagues in trauma surgery and a review of the literature (MeSH/PubMed/NLM), the decision was made to try neostigmine therapy rather than a surgical/procedural option such as colonoscopy. Results: The patient was moved to the intensive care unit and 2 mg of neostigmine was administered intravenously over 4 minutes. After 30 minutes, all abdominal examination findings had returned to baseline. No significant adverse effects were noted, and she did not redevelop abdominal distension afterward. Conclusion: This case report provides an alternative treatment modality in which neostigmine was used successfully in a burn patient after conservative medical treatment had failed. The authors believe that neostigmine may be a viable alternative to decompressive colonoscopy in burn patients for whom mechanical obstruction is properly excluded. PMID:23359843

AIM: To investigate the risk factors for gallstone disease in the general population of Chengdu, China. METHODS: This study was conducted at the West China Hospital. Subjects who received a physical examination at this hospital between January and December 2007 were included. Body mass index, blood pressure, fasting plasma glucose, serum lipid and lipoproteins concentrations were analyzed. Gallstone disease was diagnosed by ultrasound or on the basis of a history of cholecystectomy because of gallstone disease. Unconditional logistic regression analysis was used to investigate the risk factors for gallstone disease, and the Chi-square test was used to analyze differences in the incidence of metabolic disorders between subjects with and without gallstone disease. RESULTS: A total of 3573 people were included, 10.7% (384/3573) of whom had gallstone diseases. Multiple logistic regression analysis indicated that the incidence of gallstone disease in subjects aged 40-64 or ≥ 65 years was significantly different from that in those aged 18-39 years (P < 0.05); the incidence was higher in women than in men (P < 0.05). In men, a high level of fasting plasma glucose was obvious in gallstone disease (P < 0.05), and in women, hypertriglyceridemia or obesity were significant in gallstone disease (P < 0.05). CONCLUSION: We assume that age and sex are profoundly associated with the incidence of gallstone disease; the metabolic risk factors for gallstone disease were different between men and women.

Gallstone disease is a worldwide medical problem, but the incidence rates show substantial geographical variation, with the lowest rates reported in African populations. Publications in English language on gallstones which were obtained from reprint requests and PubMed database formed the basis for this paper. Data extracted from these sources included authors, country, year of publication, age and sex of patients, pathogenesis, risk factors for development of gallstones, racial distribution, presenting symptoms, complications and treatment. Gallstones occur worldwide, however it is commonest among North American Indians and Hispanics but low in Asian and African populations. High biliary protein and lipid concentrations are risk factors for the formation of gallstones, while gallbladder sludge is thought to be the usual precursor of gallstones. Biliary calcium concentration plays a part in bilirubin precipitation and gallstone calcification. Treatment of gallstones should be reserved for those with symptomatic disease, while prophylactic cholecystectomy is recommended for specific groups like children, those with sickle cell disease and those undergoing weight-loss surgical treatments. Treatment should be undertaken for a little percentage of patients with gallstones, as majority of those who harbor them never develop symptoms. The group that should undergo cholecystectomy include those with symptomatic gallstones, sickle cell disease patients with gall stones, and patients with morbid obesity who are undergoing laparotomy for other reasons.

We investigated the possible link between liver cirrhosis and gallstone risk in chronic hepatitis C (CHC) patients in China.To analyze the association between liver cirrhosis and gallstone development, we compared outcomes of 133 Chinese CHC patients with gallstones and an age-, sex-, and hepatitis C virus RNA level-matched control group of 431 CHC patients without gallstones.We found that liver cirrhosis was more prevalent in gallstone patients (40.6%) than in the control group (24.4%). Logistic regression analyses adjusting for demographic features and other gallstone risk factors revealed that liver cirrhosis increased the risk of gallstone development 2-fold (adjusted odds ratio [AOR]: 2.122; 95% confidence interval [CI]: 1.408-3.198). Moreover, multivariate analyses comparing the risk of gallstone development in liver cirrhosis patients with decompensated or compensated liver cirrhosis yielded an estimated AOR (95% CI) of 2.869 (1.277-6.450) in patients with decompensated liver cirrhosis. Gallstone risk also increased significantly with older age (>60 years) (AOR: 2.019; 95% CI: 1.017-4.009).Liver cirrhosis significantly correlates with increased risk of gallstone development in CHC patients in China. Decompensated liver cirrhosis and older age further heighten this risk in patients diagnosed with hepatitis C-related cirrhosis.

Gallstone is a high-risk factor for gallbladder pre-malignancy or malignancy (GB PM-M) but which substances of gallstones definitely assist to turn out in to GB PM-M, remains unclear. This study aimed to find out the presence of carcinogenic heavy metals in gallstones and to explore the aetiopathogenesis of gallbladder pre-malignancy and malignancy. Presence of elements in gallstones was detected by energy dispersive X-ray spectroscopy (EDS) with scanning electron microscopy (SEM) and then level of carcinogenic heavy metals was estimated in gallstones using atomic absorption spectroscopy (AAS). The experiment was carried out in gallstone samples of 46 patients with gallbladder pre-malignant and malignant condition (PM-M group) and 65 sex and age-matched patients with chronic cholecystitis (C-C group). Gallstones were also classified in to three types such as cholesterol stone, mixed stone, and black pigment stone. EDS analysis detected presence of mercury, lead, and cobalt elements in all types of gallstones of both PM-M and C-C groups. AAS analysis revealed significantly higher amount of mercury (p < 0.001), lead (p < 0.0001), cobalt (p < 0.01), and cadmium (p < 0.01) in the gallstones of PM-M than C-C groups. The presence of these heavy metals also varied among stone types of both groups. EDS phase analysis showed 'dense deposits' of these metals in gallstones. Presence of significantly higher amount of mercury, lead, cobalt, and cadmium in gallstones may play a pivotal role as risk factors in the development of gallbladder malignancy or pre-malignancy. 'Dense deposits' of these metals in the gallstones which is the first observation, may act as crucial doses of carcinogens.

Current management of gallstone pancreatitis in a university hospital. Comparison of current management of gallstone pancreatitis with recommendations in national guidelines. Tertiary care centre in Scotland. One-hundred consecutive patients admitted with gallstone pancreatitis. All patients that presented with gallstone pancreatitis over a 4-year period were audited retrospectively. Data were collated for radiological diagnosis within 48 hours, ERCP within 72 hours, CT at 6-10 days, and use of high-dependency or intensive therapy units in severe gallstone pancreatitis, and definitive treatment of gallstone pancreatitis within 2 weeks as recommended in national guidelines. Forty-six patients had severe gallstone pancreatitis and 54 patients mild pancreatitis. Etiology was established within 48 hours in 92 patients. Six (13.0%) out of the patients with severe gallstone pancreatitis were managed in a high dependency unit. Fifteen (32.6%) patients with severe gallstone pancreatitis underwent CT within 6-10 days of admission. Four (8.7%) of the 46 patients with severe gallstone pancreatitis had urgent ERCP (less than 72 hours). Overall 22/100 patients unsuitable for surgery underwent endoscopic sphincterotomy as definitive treatment. Seventy-eight patients had surgery, with 40 (51.3%) of these patients undergoing an index admission cholecystectomy, and 38 (48.7%) patients were discharged for interval cholecystectomy. Overall 81 patients with gallstone pancreatitis had definitive therapy during the index to same admission (cholecystectomy or sphincterotomy). Two (5.3%) patients were readmitted whilst awaiting interval cholecystectomy: one with acute cholecystitis and one with acute pancreatitis. There were no mortalities in this cohort. This study has highlighted difficulties in implementation of national guidelines, as the use of critical care, timing of ERCP and CT, and definitive treatment prior to discharge did not concur with national targets for gallstone pancreatitis.

Management of a hyperthyroid patient unable to take oral or rectal medication is a difficult clinical problem. The need for an alternative parenteral route of antithyroid medication administration in thyrotoxic patients occurs in certain rare cases, such as emergent gastrointestinal surgery, bowel ileus or obstruction, or severe vomiting and diarrhea. We report a simple and successful protocol for the preparation and use of intravenous methimazole (MMI) for treatment of hyperthyroidism in patients intolerant of orally and rectally administered thionamides. Five hundred milligrams of methimazole USP powder was reconstituted with pH-neutral 0.9% sodium chloride solution to a final volume of 50 mL using aseptic technique, then filtered through a 0.22-microm filter. MMI injection was administered as a slow intravenous push over 2 minutes and followed by a saline flush. A 76-year-old man, intolerant of oral and rectal medications because of an ileus and intractable diarrhea, who developed worsening thyrotoxicosis after an emergent spinal cord decompression, and a 42-year-old man with chronic liver disease and hyperthyroidism, requiring emergent exploratory laparotomy and maintenance of complete bowel rest because of persistent gastrointestinal bleeding were rendered euthyroid using intravenous MMI. Two cases of hyperthyroidism successfully treated with a preparation of intravenous MMI are described.

We evaluated the effect of alvimopan treatment vs placebo on health care utilization and costs related to gastrointestinal recovery in patients treated with radical cystectomy in a randomized, phase 4 clinical trial. Resource utilization data were prospectively collected and evaluated by cost consequence analysis. Hospital costs were estimated from 2012 Medicare reimbursement rates and medication wholesale acquisition costs. Differences in base case mean costs between the study cohorts for total postoperative ileus related costs (hospital days, study drug, nasogastric tubes, postoperative ileus related concomitant medication and postoperative ileus related readmissions) and total combined costs (postoperative ileus related, laboratory, electrocardiograms, nonpostoperative ileus related concomitant medication and nonpostoperative ileus related readmission) were evaluated by probabilistic sensitivity analysis using a bootstrap approach. Mean hospital stay was 2.63 days shorter for alvimopan than placebo (mean±SD 8.44±3.05 vs 11.07±8.23 days, p=0.005). Use of medications or interventions likely intended to diagnose or manage postoperative ileus was lower for alvimopan than for placebo, eg total parenteral nutrition 10% vs 25% (p=0.001). Postoperative ileus related health care costs were $2,340 lower for alvimopan and mean total combined costs were decreased by $2,640 per patient for alvimopan vs placebo. Analysis using a 10,000-iteration bootstrap approach showed that the mean difference in postoperative ileus related costs (p=0.04) but not total combined costs (p=0.068) was significantly lower for alvimopan than for placebo. In patients treated with radical cystectomy alvimopan decreased hospitalization cost by reducing the health care services associated with postoperative ileus and decreasing the hospital stay.

Bacteria cause pigment gallstones and can act as a nidus for cholesterol gallstone formation. Bacterial factors that facilitate gallstone formation include beta-glucuronidase (bG), phospholipase (PhL), and slime. The current study sought to determine whether bacterial factors influence the path of gallstone formation. A total of 382 gallstones were cultured and/or examined using scanning electron microscopy (SEM). Bacteria were tested for bG and slime production. Gallstone composition was determined using infrared spectrography. Ca-palmitate presence documented bacterial PhL production. Groups were identified based upon bacterial factors present: slime and bGPhL (slime/bGPhL), bGPhL only, and slime only. Influence of bacterial stone-forming factors on gallstone composition and morphology was analyzed. Bacteria were present in 75% of pigment, 76% of mixed, and 20% of cholesterol stones. Gallstones with bGPhL producing bacteria contained more pigment (71% vs. 26%, P < .0001). The slime/bGPhL group was associated (79%) with pigment stones, bGPhL was associated (56%) with mixed stones, while slime (or none) only was associated (67%) with cholesterol stones (P < .031, all comparisons). Bacterial properties determined the path of gallstone formation. Bacteria that produced all stone-forming factors promoted pigment stone formation, while those that produced only bGPhL promoted mixed stone formation. Bacteria that only produced slime lacked the ability to generate pigment solids, and consequently were more common in the centers of cholesterol stones. This shows how bacterial characteristics may govern the process of gallstone formation.

Gut microbiota dysbiosis and bacterial community assembly associated with cholesterol gallstones in large-scale study

PubMed Central

2013-01-01

Background Elucidating gut microbiota among gallstone patients as well as the complex bacterial colonization of cholesterol gallstones may help in both the prediction and subsequent lowered risk of cholelithiasis. To this end, we studied the composition of bacterial communities of gut, bile, and gallstones from 29 gallstone patients as well as the gut of 38 normal individuals, examining and analyzing some 299, 217 bacterial 16S rRNA gene sequences from 120 samples. Results First, as compared with normal individuals, in gallstone patients there were significant (P < 0.001) increases of gut bacterial phylum Proteobacteria and decreases of three gut bacterial genera, Faecalibacterium, Lachnospira, and Roseburia. Second, about 70% of gut bacterial operational taxonomic units (OTUs) from gallstone patients were detectable in the biliary tract and bacteria diversity of biliary tract was significantly (P < 0.001) higher than that of gut. Third, analysis of the biliary tract core microbiome (represented by 106 bacteria OTUs) among gallstone patients showed that 33.96% (36/106) of constituents can be matched to known bacterial species (15 of which have publicly available genomes). A genome-wide search of MDR, BSH, bG, and phL genes purpotedly associated with the formation of cholesterol gallstones showed that all 15 species with known genomes (e.g., Propionibacterium acnes, Bacteroides vulgates, and Pseudomonas putida) contained at least contained one of the four genes. This finding could potentially provide underlying information needed to explain the association between biliary tract microbiota and the formation of cholesterol gallstones. Conclusions To the best of our knowledge, this is the first study to discover gut microbiota dysbiosis among gallstone patients, the presence of which may be a key contributor to the complex bacteria community assembly linked with the presence of cholesterol gallstones. Likewise, this study also provides the first large-scale glimpse of biliary tract microbiota potentially associated with cholesterol gallstones. Such a characterization of the biliary tract core microbiome has potentially important biological and medical implications regarding the role of bacteria in the formation cholesterol gallstones.

For the first time, spatial distribution of major and trace elements has been studied in cholesterol gallstones using time-of-flight secondary mass ion mass spectrometry (TOF-SIMS). The TOF-SIMS has been used to study the elemental constituents of the center and surface parts of the gallstone sample. We have classified the gallstone sample using Fourier transform spectroscopy. The detected elements in cholesterol gallstone sample were carbon (C), hydrogen (H), calcium (Ca), sodium (Na), potassium (K), strontium (Sr), copper (Cu), iron (Fe), chromium (Cr), mercury (Hg) and lead (Pb). The detected molecules in the cholesterol gallstone were CH3 +, CO3 +, CaCO3 + and C3H+. Our results revealed that the contents of these elements in cholesterol gallstone were higher in the center part than that in the surface part. In the present paper, we have also presented the UV-Vis spectroscopic studies of the center and surface parts of the gallstone sample which indicated the presence of a higher content of cholesterol in the surface part and bilirubin in the center part.

Representative gallstones from north and southern parts of India were analyzed by a combination of physicochemical methods: X-ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), CHNS analysis, thermal analysis and Nuclear Magnetic Resonance (NMR) spectroscopy ( 1 H and 13 C). The stones from north Indian were predominantly consisting of cholesterol monohydrate and anhydrous cholesterol which was confirmed by XRD analysis. FTIR spectroscopy confirmed the presence of cholesterol and calcium bilirubinate in the south Indian gallstones. EDX spectroscopy revealed the presence of carbon, nitrogen, oxygen, calcium, sulfur, sodium and magnesium and chloride in both south Indian and north Indian gallstones. FTIR and NMR spectroscopy confirmed the occurrence of cholesterol in north Indian gallstones. The respective colour of the north Indian and south Indian gallstones was yellowish and black. The morphology of the constituent crystals of the north Indian and south Indian gallstones were platy and globular respectively. The appreciable variation in colour, morphology and composition of south and north Indian gallstones may be due to different food habit and habitat. Copyright © 2017 Elsevier B.V.

Gallstones in patients with liver cirrhosis: Incidence, etiology, clinical and therapeutical aspects

PubMed Central

Acalovschi, Monica

2014-01-01

Gallstones occur in about one third of the patients having liver cirrhosis. Pigment gallstones are the most frequent type, while cholesterol stones represent about 15% of all stones in cirrhotics. Increased secretion of unconjugated bilirubin, increased hydrolysis of conjugated bilirubin in the bile, reduced secretion of bile acids and phospholipds in bile favor pigment lithogenesis in cirrhotics. Gallbladder hypomotility also contributes to lithogenesis. The most recent data regarding risk factors for gallstones are presented. Gallstone prevalence increases with age, with a ratio male/female higher than in the general population. Chronic alcoholism, viral C cirrhosis, and non-alcoholic fatty liver disease are the underlying liver diseases most often associated with gallstones. Gallstones are often asymptomatic, and discovered incidentally. If asymptomatic, expectant management is recommended, as for asymptomatic gallstones in the general population. However, a closer follow-up of these patients is necessary in order to earlier treat symptoms or complications. For symptomatic stones, laparoscopic cholecystectomy has become the therapy of choice. Child-Pugh class and MELD score are the best predictors of outcome after cholecystectomy. Patients with severe liver disease are at highest surgical risk, therefore gallstone complications should be treated using noninvasive or minimally invasive procedures, until stabilization of the patient condition.

Protective fibrin-sealed plication of the small bowel in recurrent laparotomy.

Adhesions after recurrent abdominal operations remain extremely common and are sources of severe morbidity. Fibrin-glued plication of the small gut in a meander-like formation is supposed to guarantee a decreased risk of intestinal obstruction postoperatively. This retrospective study analyses the clinical outcome after recurrent laparotomy in children treated with bowel plication by fibrin sealant. The surgical technique of performing the fibrin-glued plication is rather simple and quick: after taking off all adhesions two to four loops of the small gut are positioned so that they lie side by side. Beginning proximal fibrin [Tissucol fibrin sealant (Baxter)] is applied between the loops; approximately 20-30 s are needed to keep the loops in position until the fibrin dries. This manoeuvre is continued until all of the small gut is fixed in one block. The gut is brought back into the abdominal cavity without loosening the loops. This fixed formation by sero-serosal adhesions or mesenterial plications is supposed to guarantee postoperative free passage. The charts of 60 children who had undergone a fibrin plication of the small bowel between 1991 and 1999 were evaluated. Additionally, questionnaires were sent to all patients, and they were invited for an examination. Sixty patients (38 boys and 22 girls) received a fibrin sealant plication because of recurrent laparotomies with heavily serosal defects or recurrent ileus because of adhesions. The youngest baby was 10 days. Since 23 patients were premature the oldest patient was 11 years old. There were no intraoperative complications attributed to the method. In the postoperative period 7/60 (12%) patients had a recurrent ileus or subileus, leading in three (5%) patients to an early relaparotomy. The fibrin-glued plication of the small bowel decreases the risk of recurrent ileus or subileus considering the high figures in the literature concerning this issue. The time-saving method is very simple and easily feasible. No side effects after the treatment with fibrin glue were observed.

Background Severely malnourished children aged under five years requiring hospital admission for diarrheal illness frequently develop ileus during hospitalization with often fatal outcomes. However, there is no data on risk factors and outcome of ileus in such children. We intended to evaluate predictive factors for ileus during hospitalization and their outcomes. Methodology/Principal findings This was a retrospective chart review that enrolled severely malnourished children under five years old with diarrhea, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh between April 2011 and August 2012. We used electronic database to have our chart abstraction from previously admitted children in the hospital. The clinical and laboratory characteristics of children with (cases = 45), and without ileus (controls = 261) were compared. Cases were first identified by observation of abnormal bowel sounds on physical examination and confirmed with abdominal radiographs. For this comparison, Chi-square test was used to measure the difference in proportion, Student’s t-test to calculate the difference in mean for normally distributed data and Mann-Whitney test for data that were not normally distributed. Finally, in identifying independent risk factors for ileus, logistical regression analysis was performed. Ileus was defined if a child developed abdominal distension and had hyperactive or sluggish or absent bowel sound and a radiologic evidence of abdominal gas-fluid level during hospitalization. Logistic regression analysis adjusting for potential confounders revealed that the independent risk factors for admission for ileus were reluctance to feed (odds ratio [OR] = 3.22, 95% confidence interval [CI] = 1.24–8.39, p = 0.02), septic shock (OR = 3.62, 95% CI = 1.247–8.95, p<0.01), and hypokalemia (OR = 1.99, 95% CI = 1.03–3.86, p = 0.04). Mortality was significantly higher in cases compared to controls (22% vs. 8%, p<0.01) in univariate analysis; however, in multivariable regression analysis, after adjusting for potential confounders such as septic shock, no association was found between ileus and death (OR = 2.05, 95% CI = 0.68–6.14, p = 0.20). In a separate regression analysis model, after adjusting for potential confounders such as ileus, reluctance to feed, hypokalemia, hypocalcemia, and blood transfusion, septic shock (OR = 168.84, 95% CI = 19.27–1479.17, p<0.01) emerged as the only independent predictor of death in severely malnourished diarrheal children. Conclusions/Significance This study suggests that the identification of simple independent admission risk factors for ileus and risk factors for death in hospitalized severely malnourished diarrheal children may prompt clinicians to be more vigilant in managing these conditions, especially in resource-limited settings in order to decrease ileus and ileus-related fatal outcomes in such children.

Genetics of gallstone disease.

Gallstone disease (GD) belongs to the most frequent disorders in gastroenterology and causes high costs in our health-care systems. Gallstones are uncommon in children but frequent in adults, in particular in women, and are triggered by exogenous risk factors. Here, we summarize the current knowledge concerning the contribution of inherited predisposition to gallstone risk. In this review, we present the current data and recent research on the genetics of gallstone disease. Several GD-predisposing gene variants have been reported, with most prominent effects being conferred by a common variant (p.D19H) of the hepatic and intestinal cholesterol transporter ABCG5/G8. A smaller group of patients might develop gallstones primarily due low phosphatidylcholine concentrations in bile as a result of loss-of-function mutations of the ABCB4 transporter (low phospholipid-associated cholelithiasis syndrome). Regardless of the origin, the risk factors for gallstones lead to the supersaturation of bile with insoluble compounds, in particular cholesterol. As result, cholesterol stones develop and present the most frequent type of gallstones. Laparoscopic cholecystectomy with low morbidity and mortality is currently the most common and effective method for the therapy of symptomatic gallbladder stones. Gallstone disease represents a multifactorial condition and previous studies have identified the major genetic contributors to gallstone formation. The increasing knowledge about the pathomechanisms of hepatobiliary metabolism and GD as well as the identification of additional risk factors might help to overcome the current invasive therapy by specific lifestyle intervention and precise molecular treatment. © 2018 Stichting European Society for Clinical Investigation Journal Foundation.

Gallstones are considered the most important risk factor for gallbladder cancer. To identify differences in the number, weight, volume, and density of gallstones associated with chronic cholecystitis (CC), gallbladder dysplasia (GD), and gallbladder cancer (GBC). A total of 125 cases were selected, of which 93 had gallstones associated with GBC and 31 had gallstones associated with GD. The controls were those with CC, matched by sex and age. The number, weight, volume, and density of these gallstones were examined in order to determine differences and relative cancer risk. Number: Multiple gallstones were present in over 76% of cases (GBC and GD) and controls (P = ns). The average number of multiple stones was 21 in GBC versus 14 in controls (P < 0.01). Weight: The average weight of the gallstones was 9.6 g in GBC versus 6.0 g in controls (P = 0.0004). The average weight in multiple stones over 10 g had strong association with GBC (P = 0.0006). Volume: The average volume was 11.7 and 6.48 ml in GBC and controls (P = 0.0002). Average volumes of 6, 8, and 10 ml had a relative cancer risk of 5, 7, and 11 times, respectively. Size: No differences were shown between GBC, GD, and controls. The volume of gallstones associated with other risk factors of GBC may be helpful in prioritizing cholecystectomies in symptomatic patients. Copyright 2006 Wiley-Liss, Inc.

Gallstone disease in Peruvian coastal natives and highland migrants

BACKGROUND—In a previous study, we found that gallstones were a common occurrence in the high altitude villages of the Peruvian Andes.
AIMS—To determine if high altitude (⩾ 1500 m) is a contributing risk factor for gallstone disease.
METHODS—We conducted a cross sectional study in a periurban community in Lima, Peru, and compared the prevalence of gallstone disease between coastal natives, highland (Sierra) natives and Sierra natives who had migrated to the coast. We also compared the prevalence rates from this study with those from a previous study conducted at high altitude. We examined 1534 subjects >15 years of age for gallstone disease. Subjects were interviewed for the presence or absence of risk factors.
RESULTS—Gallstone disease was more common in females (16.1 cases per 100, 95% CI 13.8-18.2) than in males (10.7 per 100, 95% CI 8.0-13.4). Females had a greater risk of gallstone disease, especially if they had used oral contraception and/or had four or more children. The age adjusted prevalence was not significantly different between coastal natives, Sierra migrants, and Andean villagers. The prevalence of gallstone disease was not associated with time since migration or with having native Sierra parents. After adjusting for other risk factors, Sierra natives who migrated to the coast had a lower prevalence of gallstone disease than coastal natives (odds ratio 0.74, 95% CI 0.58-0.94).
CONCLUSIONS—This study indicates that high altitude is not a positive risk factor for gallstone disease and confirms that this disease is common in Peruvians, which may be attributable to Peruvian-Indian ethnicity.

Cystic fibrosis is an autosomal recessive disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator gene. This disorder produces a variable phenotype including lung disease, pancreatic insufficiency, and meconium ileus plus bilateral agenesis of the vas deferens causing obstructive azoospermia and male infertility. Preimplantation genetic diagnosis is an alternative that allows identification of embryos affected by this or other genetic diseases. We report a case of couple with cystic fibrosis; the woman had the I148 T mutation and the man had the Delta F508 gene mutation. The couple underwent in vitro fertilization, associated with preimplantation genetic diagnosis, and with subsequent selection of healthy embryos for uterine transfer. The result was an uneventful pregnancy and delivery of a healthy male baby.

A 41-year-old woman was admitted to our hospital with abdominal pain that developed about 1 year after a Cesarean section. Pelvic computed tomography (CT) revealed diffuse dilation of the small intestine with fluid shadows and a pelvic tumor 55 mm in diameter. The density of the tumor, which was not enhanced by intravenous contrast medium, was diffuse and similar to that of muscular tissue, whereas the density of a capsule surrounding the mass was relatively high. T1- and T2-weighted pelvic magnetic resonance imaging (MRI) of the tumor revealed the same diffuse low-intensity signals as muscular tissue, and diffuse high-intensity signals, respectively. The CT and MRI findings were consistent with those of a gastrointestinal stromal tumor (GIST) causing ileus of the small intestine. As inserting an ileus tube did not improve her symptoms, the patient was scheduled for tumor resection. The operative findings revealed a hard, solid tumor adhering to the surrounding small intestine. The macroscopic findings revealed that the tumor consisted of layers of stratified gauze surrounded by a thick granulomatous wall. The gossypiboma was considered to have originated from gauze that had been left behind after the Cesarean section. If a patient has a history of surgery, the possibility of gossypiboma should be considered when CT or MRI findings indicate features of GIST. PMID:22679410

Nausea and vomiting is a common and distressing symptom complex in patients with far-advanced cancer, affecting up to 60% of individuals at some stage of their illness. The current approach to the palliative care of patients with nausea and vomiting is based on identifying the cause, understanding its pathophysiology and knowing the pharmacology of the drugs available for its amelioration. The following six main syndromes are identified: gastric stasis, biochemical, raised intracranial pressure, vestibular, mechanical bowel obstruction and ileus. A careful history, focused physical examination and appropriate investigations are needed to elucidate the syndrome and its cause, so that therapy is rational. Drugs are the mainstay of treatment in terminal cancer, and the main classes of antiemetic agents are prokinetics, dopamine antagonists, antihistamines, anticholinergics and serotonin antagonists. Dexamethasone and octreotide are also used, especially in bowel obstruction. Non-drug measures are important in relieving the associated distress. Patients should be able to die comfortably, without tubes. Despite decades of practice affirming this approach, the evidence base is weak and well designed studies are urgently needed.

Several studies have examined the role of ursodeoxycholic acid (UDCA) for the prevention of cholelithiasis (gallstones) following rapid weight loss from restrictive diets, vertical band gastroplasty, and Roux-en-Y gastric bypass. However, to date, there have been no prospective, controlled studies examining the role of UDCA for the prevention of gallstones following sleeve gastrectomy (SG). This study was conducted to identify the effectiveness of UDCA for prevention of gallstones after SG. Following SG, eligible patients were randomized to a control group who did not receive UDCA treatment or to a group who were prescribed 300 mg UDCA twice daily for 6 months. Gallbladder ultrasounds were performed preoperatively and at 6 and 12 months postoperatively. Patients with positive findings preoperatively were excluded from the study. Compliance with UDCA was assessed. Between December 2011 and April 2013, 37 patients were randomized to the UDCA treatment arm and 38 patients were randomized to no treatment. At baseline, the two groups were similar. At 6 months, the UDCA group had a statistically significant lower incidence of gallstones (p = 0.032). Analysis revealed no significant difference in gallstones between the two groups at 1 year (p = 0.553 and p = 0.962, respectively). The overall gallstone formation rate was 29.8%. The incidence of gallstones is higher than previously estimated in SG patients. UDCA significantly lowers the gallstone formation rate at 6 months postoperatively.

Gallstones obtained from patients from the north-east region of India (Assam) were studied using laser-induced breakdown spectroscopy (LIBS) technique. LIBS spectra of the different layers (in cross-section) of the gallstones were recorded in the spectral region 200-900 nm. Several elements, including calcium, magnesium, manganese, copper, silicon, phosphorus, iron, sodium and potassium, were detected in the gallstones. Lighter elements, including carbon, hydrogen, nitrogen and oxygen were also detected, which demonstrates the superiority of the LIBS technique over other existing analytical techniques. The LIBS technique was applied to investigate the evolution of C(2) swan bands and CN violet bands in the LIBS spectra of the gallstones in air and an argon atmosphere. The different layers (dark and light layers) of the gallstones were discriminated on the basis of the presence and intensities of the spectral lines for carbon, hydrogen, nitrogen, oxygen and copper. An attempt was also made to correlate the presence of major and minor elements in the gallstones with the common diet of the population of Assam.

Gallstones from 82 patients were examined under a scanning electron microscope for evidence of bacteria, and the findings were compared with the clinical manifestations of the disease. Bacteria were present in 68% of pigment stones and the pigment portions of 80% of composite stones. These gallstones were referred to as infectious stones. No bacteria were found in cholesterol gallstones. Acute cholangitis was diagnosed in 52% of patients with infectious stones and in 18% of patients with noninfectious stones. Over half of the patients with noninfectious stones presented with mild symptoms. Infectious stones were more often associated with a previous common duct exploration, an urgent operation, infected bile, a common duct procedure, and complications. These data show that gallstone disease is more virulent in patients whose gallstones contain bacteria.

IR Spectroscopy and X-Ray Phase Analysis of the Chemical Composition of Gallstones

The composition of the inorganic and organic parts of gallstones was investigated by x-ray phase analysis and IR spectroscopy. Cholesterol, bilirubin, calcium bilirubinate, calcium carbonate, and calcium hydrogen phosphate are all found in gallstones. The major component is cholesterol. A gallstone was separated into layers and the inorganic part was separated out by annealing. Inorganic compounds were found to predominate in the outer layer of the gallstone, which is related to the mechanism of its formation. The inorganic part contains calcium carbonate, present in both the calcite and waterite modifications.

To determine behavioural, dietary and other common factors associated with new cases of gallstones, diagnosed by ultrasonography, in a prospective cohort study conducted in southern Italy. Between May 1985 and June 1986, systematic sampling from the electoral register of Castellana, a small town in southern Italy, yielded 2472 subjects who had had their gallbladder checked for gallstones by ultrasonography. Between May 1992 and June 1993, 1962 out of the 2235 (87.7%) subjects without gallstones at baseline agreed to a further ultrasound examination. At the first survey a standardized questionnaire was administered, inquiring about medical history, diet, cigarette smoking and other behavioural characteristics. Height and weight were also measured, and blood levels of glucose, cholesterol, HDL-cholesterol and triglycerides were determined by standard methods. The same variables were measured at the second survey. The diagnosis of gallstones was made with the same echograph by echographists working in the same department. Multiple logistic regression was used to determine which factors measured at the first survey were associated with the incident cases of gallstones. One hundred and four subjects had developed gallstones, an incidence of 9.7 per 1000 persons per year. Age, body mass index (BMI), weight change, a history of diabetes, constipation (shown by use of laxatives), cigarette smoking, years of schooling, consumption of fried foods and excessive oil, and pregnancy in females, were positively associated with the incidence of gallstones. Consumption of wine, coffee, fish and wholemeal bread was inversely associated. Sex, family history of cholelithiasis, use of oral contraceptives and serum lipids were not independent risk factors for gallstones. The results of this study confirm many gallstone-associated factors reported in previous cross-sectional and case-control studies, as well as in other cohort studies based on the clinical diagnosis of gallstones, such as BMI, ageing and wine consumption. Furthermore, use of laxatives, considered a proxy of constipation, appears to be another important independent risk factor for gallstones.

Background & Aims Neonatal intestinal obstruction (meconium ileus or MI) occurs in 15% of patients with cystic fibrosis (CF). Our aim was to determine the relative contribution of genetic and non-genetic modifiers to the development of this major complication of CF. Methods Using clinical data and DNA collected by the CF Twin and Sibling Study, 65 monozygous twin pairs, 23 dizygous twin/triplet sets, and 349 sets of siblings with CF were analyzed for MI status, significant covariates, and genome-wide linkage. Results Specific mutations in CFTR, the gene responsible for CF, correlated with MI indicating a role for CFTR genotype. Monozygous twins showed substantially greater concordance for MI than dizygous twins and siblings (p=1×10−5) demonstrating that modifier genes independent of CFTR contribute substantially to this trait. Regression analysis revealed that MI was correlated with distal intestinal obstruction syndrome (DIOS; p=8×10−4). Unlike MI, concordance analysis indicated that the risk for development of DIOS in CF patients is primarily due to non-genetic factors. Regions of suggestive linkage (logarithm of the odds of linkage >2.0) for modifier genes that cause MI (chromosomes 4q35.1, 8p23.1, and 11q25) or protect from MI (chromosomes 20p11.22 and 21q22.3) were identified by genome-wide analyses. These analyses did not support the existence of a major modifier gene within the CFM1 region on chromosome 19 that had previously been linked to MI. Conclusions The CFTR gene along with two or more modifier genes are the major determinants of intestinal obstruction in newborn CF patients, while intestinal obstruction in older CF patients is primarily due to non-genetic factors.

Previous small studies have shown either no difference or a lower risk of symptomatic gallstone disease in vegetarians than in non-vegetarians. This study examined the incidence of symptomatic gallstone disease in a cohort of British vegetarians and non-vegetarians, and investigated the associations between nutrient intake and risk of symptomatic gallstone disease. The data were analysed from 49 652 adults enroled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study, one-third of whom were vegetarian. The linked databases of hospital records were used to identify incident cases. Risk by diet group was estimated using Cox proportional hazards models. Further analysis quantified risk by intakes of selected macronutrients. There were 1182 cases of symptomatic gallstone disease during 687 822 person-years of follow-up (mean=13.85 years). There was a large significant association between increasing body mass index (BMI) and risk of developing symptomatic gallstone disease (overall trend P<0.001). After adjustment for BMI and other risk factors, vegetarians had a moderately increased risk compared with non-vegetarians (HR: 1.22; 95% CI: 1.06-1.41; P=0.006). Although starch consumption was positively associated with gallstones risk (P=0.002 for trend), it did not explain the increased risk in vegetarians. There is a highly significant association of increased BMI with risk of symptomatic gallstone disease. After adjusting for BMI, there is a small but statistically significant positive association between vegetarian diet and symptomatic gallstone disease.

Background Gallstones and kidney stones are known complications of inflammatory bowel diseases (IBD). Risk factors have been insufficiently studied and explanatory studies date back up to 30 years. It remains unclear, whether improved treatment options also influenced risk factors for these complications. Objectives Identifying risk factors for gallstones and kidney stones in IBD patients. Methods Using data from the Swiss Inflammatory Bowel Disease Cohort Study we assessed associations of diseases characteristics with gallstones and kidney stones in univariate and multivariate logistic regression analyses. Results Out of 2323 IBD patients, 104 (7.8%) Crohn’s disease (CD) and 38 (3.8%) ulcerative colitis (UC) patients were diagnosed with gallstones. Significant risk factors for gallstones were diagnosis of CD, age at diagnosis, disease activity and duration, NSAID intake, extra-intestinal manifestations and intestinal surgery. Kidney stones were described in 61 (4.6%) CD and 30 (3.0%) UC patients. Male gender, disease activity, intestinal surgery, NSAID usage and reduced physical activity were significant risk factors. Hospitalization was associated with gallstones and kidney stones. The presence of gallstones increased the risk for kidney stones (OR 4.87, p<0.001). Conclusion The diagnosis of CD, intestinal surgery, prolonged NSAID use, disease activity and duration and bowel stenosis were significantly associated with cholecystonephrolithiasis in IBD.

2016-07-01

Gallstone formation is the result of a complex interaction between genetic and nongenetic factors. We searched and reviewed the available literature to define how the primary prevention of gallstones (cholesterol gallstones in particular) could be applied in general practice. Electronic bibliographical databases were searched. Prospective and retrospective cohort studies and case-controlled studies were analyzed and graded for evidence quality. The epidemiological data confirmed that genetic factors are estimated to account for only approximately 25% of the overall risk of gallstones, while metabolic/environmental factors are at least partially modifiable in stone-free risk groups, and are thus modifiable by primary prevention measures related to diet, lifestyle, and environmental factors (i.e., rapid weight loss, bariatric surgery, somatostatin or analogues therapy, transient gallbladder stasis, and hormone therapy). There is no specific recommendation for the secondary prevention of recurrent gallstones. Family physicians can contribute to preventing gallstones due to their capability to identify and effectively manage several risk factors discussed in this study. Although further studies are needed to better elucidate the involvement of epigenetic factors that may regulate the effect of environment and lifestyle on gene expression in the primary prevention of gallstone formation, preventive interventions are feasible and advisable in the general practice setting.

Cystic fibrosis (CF) pigs develop disease with features remarkably similar to those in people with CF, including exocrine pancreatic destruction, focal biliary cirrhosis, micro-gallbladder, vas deferens loss, airway disease, and meconium ileus. Whereas meconium ileus occurs in 15% of babies with CF, the penetrance is 100% in newborn CF pigs. We hypothesized that transgenic expression of porcine CF transmembrane conductance regulator (pCFTR) cDNA under control of the intestinal fatty acid–binding protein (iFABP) promoter would alleviate the meconium ileus. We produced 5 CFTR–/–;TgFABP>pCFTR lines. In 3 lines, intestinal expression of CFTR at least partially restored CFTR-mediated anion transport and improved the intestinal phenotype. In contrast, these pigs still had pancreatic destruction, liver disease, and reduced weight gain, and within weeks of birth, they developed sinus and lung disease, the severity of which varied over time. These data indicate that expressing CFTR in intestine without pancreatic or hepatic correction is sufficient to rescue meconium ileus. Comparing CFTR expression in different lines revealed that approximately 20% of wild-type CFTR mRNA largely prevented meconium ileus. This model may be of value for understanding CF pathophysiology and testing new preventions and therapies. PMID:23676501

Gallstone disease is highly prevalent and is associated with systemic inflammation. To determine whether screen-detected gallstones or cholecystectomy are associated with the occurrence of autoimmune and autoinflammatory diseases and the most common subgroups thereof. A cohort study of three randomly selected general population samples from Copenhagen was performed. Participants (n = 5928) were examined in the period 1982-1992, underwent abdominal ultrasound examination to detect gallstone disease, and followed through national registers until December 2014 (median 24.7 years) for occurrence of immunological diseases. Multivariable Cox regression analyses were performed. Gallstone disease was identified in 10% (591/5928) of participants, of whom 6.8% had gallstones and 3.2% had cholecystectomy at baseline. Gallstone disease was associated with incidence of autoimmune diseases (12.9% versus 7.92%; hazard ratio 1.46; 95% confidence interval [CI], [1.11;1.91]), diabetes mellitus type 1 (5.95% versus 3.67%; 1.53; [1.02;2.30]), and autoimmune thyroid disease (3.70% versus 1.59%; 2.06; [1.26;3.38]). Rheumatoid arthritis, autoinflammatory diseases, or any subgroups thereof were not associated. In a large general population sample, screen-detected gallstone disease was associated with the development of autoimmune diseases during long-term follow-up. Future research efforts are needed to further explore common disease mechanisms. Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

Bacteria are traditionally accorded a greater role in pigment gallstone formation in Eastern populations. Stone color is thought to predict the presence of bacteria; that is, black stones (Western predominant) are supposedly sterile and brown stones (Eastern predominant) contain bacteria. We previously reported that, regardless of appearance, most pigment gallstones contain bacteria. This study examined, in a large Western population (370 patients), the incidence, appearance, and chemical composition of pigment stones, and the characteristics of gallstone bacteria. One hundred eighty-six pigment stones were obtained aseptically. Bacteria were detected by means of scanning electron microscopy and gallstone culture. Chemical composition was determined by infrared spectroscopy. Bacteria were tested for slime and beta-glucuronidase production. Seventy-three percent of pigment stones contained bacteria. Choledocholithiasis was associated with gallstone bacteria. Ca-bilirubinate was present in all pigment stones. Ca-palmitate was characteristic of infected stones, and more than 75% Ca-carbonate was characteristic of sterile stones. Neither chemical composition nor stone appearance predicted the presence of bacteria. Ninety-five percent and 67% of infected pigment stones contained bacteria that produced slime and beta-glucuronidase, respectively. Most pigment stones contained bacteria that produced beta-glucuronidase, slime, and phospholipase, factors that facilitate stone formation. Thus bacteria have a major role in Western pigment gallstone formation. Furthermore, gallstone color did not predict composition or bacterial presence.

Background Cholelithiasis is the gallstone disease (GSD) where stones are formed in the gallbladder. The main function of the gallbladder is to concentrate bile by the absorption of water and sodium. GSD has high prevalence among elderly adults. There are three major types of gallstones found in patients, White, Black and Brown. The major chemical component of white stones is cholesterol. Black and brown stones contain different proportions of cholesterol and bilirubin. The pathogenesis of gallstones is not clearly understood. Analysis of the chemical composition of gallstones using various spectroscopic techniques offers clues to the pathogenesis of gallstones. Recent years has seen an increasing trend in the number of cases involving children. The focus of this study is on the analysis of the chemical composition of gallstones from child and adult patients using spectroscopic methods. Methods In this report, we present FTIR spectroscopic studies and fluorescence microscopic analysis of gallstones obtained from 67 adult and 21 child patients. The gallstones were removed during surgical operations at Soroka University Medical Center. Results Our results show that black stones from adults and children are rich in bilirubin. Brown stones are composed of varying amounts of bilirubin and cholesterol. Green stones removed from an adult, which is rare, was found to be composed mainly of cholesterol. Our results also indicated that cholesterol and bilirubin could be the risk factors for gallstone formation in adults and children respectively. Fluorescence micrographs showed that the Ca-bilirubinate was present in all stones in different quantities and however, Cu-bilirubinate was present only in the mixed and black stones. Conclusions Analysis based on FTIR suggest that the composition of black and brown stones from both children and adults are similar. Various layers of the brown stone from adults differ by having varying quantities of cholesterol and calcium carbonate. Ring patterns observed mainly in the green stone using fluorescence microscopy have relevance to the mechanism of the stone formation. Our preliminary study suggests that bilirubin and cholesterol are the main risk factors of gallstone disease. PMID:11872150

This study aimed to investigate the clinical value of spectral computed tomography (CT) in the detection of cholesterol gallstones from surrounding bile. This study was approved by the institutional review board. The unenhanced spectral CT data of 24 patients who had surgically confirmed cholesterol gallstones were analyzed. Lipid concentrations and CT numbers were measured from fat-based material decomposition image and virtual monochromatic image sets (40-140 keV), respectively. The difference in lipid concentration and CT number between cholesterol gallstones and the surrounding bile were statistically analyzed. Receiver operating characteristic analysis was applied to determine the diagnostic accuracy of using lipid concentration to differentiate cholesterol gallstones from bile. Cholesterol gallstones were bright on fat-based material decomposition images yielding a 92% detection rate (22 of 24). The lipid concentrations (552.65 ± 262.36 mg/mL), CT number at 40 keV (-31.57 ± 16.88 HU) and 140 keV (24.30 ± 5.85 HU) for the cholesterol gallstones were significantly different from those of bile (-13.94 ± 105.12 mg/mL, 12.99 ± 9.39 HU and 6.19 ± 4.97 HU, respectively). Using 182.59 mg/mL as the threshold value for lipid concentration, one could obtain sensitivity of 95.5% and specificity of 100% with accuracy of 0.994 for differentiating cholesterol gallstones from bile. Virtual monochromatic spectral CT images at 40 keV and 140 keV provide significant CT number differences between cholesterol gallstones and the surrounding bile. Spectral CT provides an excellent detection rate for cholesterol gallstones. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc. All rights reserved.

Pancreatitis is a source of substantial morbidity and health cost in the United States. Little is known about how diet might contribute to its pathogenesis. To characterize dietary factors that are associated with risk of pancreatitis by disease subtype, we conducted a prospective analysis of 145,886 African Americans, Native Hawaiians, Japanese Americans, Latinos, and whites in the Multiethnic Cohort. In the Multiethnic Cohort (age at baseline, 45-75 y), we identified cases of pancreatitis using hospitalization claim files from 1993 through 2012. Patients were categorized as having gallstone-related acute pancreatitis (AP) (n = 1210), AP not related to gallstones (n = 1222), or recurrent AP or suspected chronic pancreatitis (n = 378). Diet information was obtained from a questionnaire administered when the study began. Associations were estimated by hazard ratios and 95% confidence intervals using Cox proportional hazard models adjusted for confounders. Dietary intakes of saturated fat (P trend = .0011) and cholesterol (P trend = .0008) and their food sources, including red meat (P trend < .0001) and eggs (P trend = .0052), were associated positively with gallstone-related AP. Fiber intake, however, was associated inversely with gallstone-related AP (P trend = .0005) and AP not related to gallstones (P trend = .0035). Vitamin D, mainly from milk, was associated inversely with gallstone-related AP (P trend = .0015), whereas coffee consumption protected against AP not related to gallstones (P trend < .0001). With the exception of red meat, no other dietary factors were associated with recurrent acute or suspected chronic pancreatitis. Associations between dietary factors and pancreatitis were observed mainly for gallstone-related AP. Interestingly, dietary fiber protected against AP related and unrelated to gallstones. Coffee drinking protected against AP not associated with gallstones. Further studies are warranted to confirm our findings. Copyright © 2017 AGA Institute. Published by Elsevier Inc.

To evaluate whether metabolic syndrome is associated with gallstones, independent of hepatitis C infection or chronic kidney disease (CKD), in a non-diabetic population. A total of 8,188 Chinese adult participants that underwent a self-motivated health examination were recruited into the final analysis after excluding the subjects who had a history of cholecystectomy, diabetes mellitus, or were currently using antihypertensive or lipid-lowering agents. Gallstones were defined by the presence of strong intraluminal echoes that were gravity-dependent or that attenuated ultrasound transmission. A total of 447 subjects (5.5%) had gallstones, with 239 (5.1%) men and 208 (6.0%) women. After adjusting for age, gender, obesity, education level, and lifestyle factors, included current smoking, alcohol drinking, regular exercise, hepatitis B, hepatitis C, and CKD, there was a positive association between metabolic syndrome and gallstones. Moreover, as compared to subjects without metabolic abnormalities, subjects with one, two, and three or more suffered from a 35, 40, and 59% higher risk of gallstones, respectively. Non-diabetic subjects with metabolic syndrome had a higher risk of gallstones independent of hepatitis C or CKD, and a dose-dependent effect of metabolic abnormalities also exists.

Acute pancreatitis is a common diagnosis worldwide, with gallstone disease being the most prevalent cause (50%). The American College of Gastroenterology recommends urgent endoscopic retrograde cholangiopancreatography (ERCP) (within 24 h) for patients with biliary pancreatitis accompanied by cholangitis. Most international guidelines recommend that ERCP be performed within 72 h in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, but the optimal timing for endoscopy is controversial. We investigated the optimal timing for ERCP in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, and whether performing endoscopy within 24 h is superior to performing it after 24 h. We analyzed the clinical data of 505 patients with newly diagnosed acute pancreatitis, from January 1, 2005 to December 31, 2014. We divided the patients into two groups according to the timing of ERCP: < 24 h (urgent) and 24-72 h (early).Among the 505 patients, 73 were diagnosed with biliary pancreatitis and a bile duct obstruction without cholangitis. The mean age of the patients was 55 years (range: 26-90 years). Bile duct stones and biliary sludge were identified on endoscopy in 45 (61.6%) and 11 (15.0%) patients, respectively. The timing of ERCP within 72 h was not associated with ERCP-related complications (P = 0.113), and the total length of hospital stay was not different between urgent and early ERCP (5.9 vs. 5.7 days, P = 0.174). No significant differences were found in total length of hospitalization or procedural-related complications, in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, according to the timing of ERCP (< 24 h vs. 24-72 h).

Epidemiologic evidence on coffee consumption reducing the risk of gallstone disease has been contradictory. To perform a meta-analysis of observational studies, to investigate an association and dose-response of coffee consumption with gallstone disease. We used PubMed and EMBASE databases to identify all published studies before June 2015. A random-effects model was used to compute a pooled relative risk (RR) and corresponding 95% confidence intervals (CIs). One case-control study and five prospective cohort studies (with seven cohorts) involving 227,749 participants and 11,477 gallstone disease cases were included. Coffee consumption was significantly associated with a reduced risk of gallstone disease (RR, 0.83; 95% CI, 0.76 to 0.89; I(2) = 35.9%), based on prospective studies; specifically, we observed an inverse relation in females, but not in males. The case-control study did not reveal any association between coffee and gallstone disease (OR, 0.99; 95% CI, 0.64 to 1.53). In a dose-response analysis, the RR of gallstone disease was 0.95 (95% CI, 0.91 to 1.00; P = 0.049) per 1 cup/day of coffee consumption. A significant nonlinear dose-response association was also identified (P for nonlinearity = 0.0106). For people who drank 2, 4 and 6 cups of coffee per day, the estimated RRs of gallstone disease were 0.89 (95% CI, 0.79 to 0.99), 0.81 (95% CI, 0.72 to 0.92) and 0.75 (95% CI, 0.64 to 0.88), respectively, compared with the lowest level drinkers. This study suggests that coffee consumption is related to a significantly decreased risk of gallstone disease. © 2015 John Wiley & Sons Ltd.

To assess the prevalence of gallstone disease and identify associated risk factors in rheumatoid arthritis (RA) patients compared to the general population. Eighty-four women with rheumatoid arthritis were included in the study. Each patient was assessed via a structured interview, physical examination, abdominal ultrasound and blood test including lipid profile. The prevalence of gallstone disease in rheumatoid arthritis was compared with data from a study of the Spanish population matched by age groups. Twenty-eight of the 84 women had gallstone disease (33.3%). RA women with and without gallstone disease were similar in most of the variables assessed, except for older age and menopausal status in the former. A greater prevalence of gallstone disease was seen in rheumatoid arthritis patients compared to the general population of the same age; however, the differences were significant only in women aged 60 or older (45.5% versus 23.1% respectively, P-value .008). The age-adjusted OR of developing gallstone disease in RA women compared with general population women was 2,3 (95% CI: 1.3-4.1). A significantly higher HDL3-c subfraction and higher apoA-I/HDL and HDL3-c/TC ratios were observed in patients with gallstone disease. Women with rheumatoid arthritis may have a predisposition to gallstones that can manifest in middle or older age compared with women in the general population. This situation could be related to chronic inflammation and HDL metabolism. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología.

Targets for Current Pharmacological Therapy in Cholesterol Gallstone Disease

2010-01-01

Summary Gallstone disease is a frequent condition throughout the world and cholesterol stones are the most frequent form in western countries. Current standard treatment of symptomatic gallstone subjects remains laparoscopic cholecystectomy. The selection of patients amenable for non-surgical, medical therapy is of key importance: a careful analysis should consider the natural history of the disease and the overall costs of therapy. Only patients with mild symptoms and small, uncalcified cholesterol gallstones in a functioning gallbladder with a patent cystic duct will be considered for oral litholysis by the hydrophilic ursodeoxycholic acid (UDCA) hopefully leading to cholesterol desaturation of bile and progressive stone dissolution. Recent studies have raised the possibility that cholesterol-lowering agents which inhibit hepatic cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe), or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis may offer, alone or in combination, additional medical therapeutic tools for treating cholesterol gallstones. Recent perspectives on medical treatment of cholesterol gallstone disease will be discussed in this chapter. PMID:20478485

Diet and cholesterol gallstones. A further study.

In a first study, a population of 1,045 women from 20 to 61 years old has been studies. 24 (2.3%) were known to have gallstones. After excluding these 24 cases, 214 were drawn from the same population and accepted an oral cholecystography. 11 cases of stones (5.1%) were discovered. The diet of these 11 patients and of the 202 women without gallstones was not significantly different. In a second study, the diet of 50 patients with known gallstones and the diet of 50 matched controls have been compared. No significant difference between the two groups can be demonstrated for calories, protein, fat or carbohydrates intake. These results are compared to previous results which showed overconsumption of food in gallstone patients. The method for all studies being similiar, it seems that the dietetic factors are now less important in cholesterol stones pathogenesis than during the period which followed the second world war starvation in southeast France. The assumption that undernutrition diminishes the chance for a women to develop gallstones is proposed.

A 16-year-old boy had a past medical history of primary hypogonadism, due to bilateral anorchia. He presented with gallstones located in the gallbladder and a mild dilatation of the intrahepatic biliary tree. The histology study reported cholesterol gallstones. The patient had been treated with testosterone replacement therapy since infancy. We suggest a possible correlation between testosterone replacement therapy and the presence of cholesterol gallstones. Copyright © 2018 Asociación Mexicana de Gastroenterología.

We aim to review the available literature on obese patients treated with ursodeoxycholic acid (UDCA) in order to prevent gallstone formation after bariatric surgery. A systematic literature search was performed in PubMed, Cochrane library, and Scopus databases, in accordance with the PRISMA guidelines. Eight studies met the inclusion criteria incorporating 1355 patients. Random-effects meta-analysis showed a lower incidence of gallstone formation in patients taking UDCA. Subgroup analysis reported fewer cases of gallstone disease in the UDCA group in relation to different bariatric procedures, doses of administered UDCA, and time from bariatric surgery. Adverse events were similar in both groups. Fewer patients required cholecystectomy in UDCA group. No deaths were reported. The administration of UDCA after bariatric surgery seems to prevent gallstone formation.

We have investigated comprehensively the effects of thyroid function on gallstone formation in a mouse model. Gonadectomized gallstone-susceptible male C57BL/6 mice were randomly distributed into three groups each of which received an intervention to induce hyperthyroidism, hypothyroidism, or euthyroidism. After 5 weeks of feeding a lithogenic diet of 15% (w/w) butter fat, 1% (w/w) cholesterol, and 0.5% (w/w) cholic acid, mice were killed for further experiments. The incidence of cholesterol monohydrate crystal formation was 100% in mice with hyperthyroidism, 83% in hypothyroidism, and 33% in euthyroidism, the differences being statistically significant. Among the hepatic lithogenic genes, Trβ was found to be up-regulated and Rxr down-regulated in the mice with hypothyroidism. In contrast, Lxrα, Rxr, and Cyp7α1 were up-regulated and Fxr down-regulated in the mice with hyperthyroidism. In conclusion, thyroid dysfunction, either hyperthyroidism or hypothyroidism, promotes the formation of cholesterol gallstones in C57BL/6 mice. Gene expression differences suggest that thyroid hormone disturbance leads to gallstone formation in different ways. Hyperthyroidism induces cholesterol gallstone formation by regulating expression of the hepatic nuclear receptor genes such as Lxrα and Rxr, which are significant in cholesterol metabolism pathways. However, hypothyroidism induces cholesterol gallstone formation by promoting cholesterol biosynthesis. PMID:27381728

In very low birth weight infants abdominal emergency surgery may result in ileostomy formation. We observed a frequent stoma complications in these patients. This retrospective analysis put light on ileostomy-related problems and complications in very low birth weight (VLBW) infants. In a seven-year retrospective chart review (2008 - 2014) infants with ileostomy formation weighing less than 1500 grams at time of operation were identified and reviewed. Data analysis included demographic data, complications and short term outcomes. Thirty patients were included. Ileostomy was formed for spontaneous intestinal perforation (SIP) (n=17), meconium obstruction of prematurity (MOP) (n=6), midgut volvulus (MV) (n=5), necrotizing enterocolitis (NEC) (n=1) and Hirschsprung's disease (HD) (n=1). Three patients died before ileostomy reversal was considered. In seven patients planned ileostomy reversal was done. Twenty infants had stoma related complications (stoma prolapse, prestomal obstruction, stoma retraction, high output stoma, peristomal skin excoriation, and stomal ischemia). Complications did not correlate with underlying diseases. Stomal complications necessitated earlier stoma reversal (mean 62 days). Postoperative complications after stoma reversal occurred in three children (wound dehiscence, adhesion ileus, anastomotic stricture). Although ileostomy related complications are frequent in very low birth weight infants, mortality is low. Morbidity is manageable.

Bacterial translocation as a direct cause of sepsis is an attractive hypothesis that presupposes that in specific situations bacteria cross the intestinal barrier, enter the systemic circulation, and cause a systemic inflammatory response syndrome. Critically ill children are at increased risk for bacterial translocation, particularly in the early postnatal age. Predisposing factors include intestinal obstruction, obstructive jaundice, intra-abdominal hypertension, intestinal ischemia/reperfusion injury and secondary ileus, and immaturity of the intestinal barrier per se. Despite good evidence from experimental studies to support the theory of bacterial translocation as a cause of sepsis, there is little evidence in human studies to confirm that translocation is directly correlated to bloodstream infections in critically ill children. This paper provides an overview of the gut microflora and its significance, a focus on the mechanisms employed by bacteria to gain access to the systemic circulation, and how critical illness creates a hostile environment in the gut and alters the microflora favoring the growth of pathogens that promote bacterial translocation. It also covers treatment with pre- and pro biotics during critical illness to restore the balance of microbial communities in a beneficial way with positive effects on intestinal permeability and bacterial translocation.

Little is known about the natural history and pathogenesis of small gallbladder polyps (<10 mm, usually of the cholesterol type), particularly in Western populations. It is unclear if these polyps and gallstones represent different aspects of the same disease. The aim of this study was to characterize the natural history and pathogenesis of small gallbladder polyps. Fifty-six Caucasian patients with small gallbladder polyps, 30 matched gallstone patients, and 30 controls were enrolled in this 5-year prospective study. Patients underwent a symptomatic questionnaire, abdominal ultrasonography, and ultrasonographic evaluation of gallbladder motility at baseline and yearly intervals for 5 years. Cholesterol saturation index, cholesterol crystals in bile, and apolipoprotein E genotype were also determined. Most patients with polyps (mean size: 5.3 mm) were men (61%), asymptomatic, and had multiple polyps (57%). Polyps did not change in 91% of patients during follow-up. No subject experienced biliary pain or underwent cholecystectomy; four developed gallstones. Cholesterol saturation index was higher in patients with polyps or gallstones than in controls (P<0.05). Cholesterol crystals were more frequent in patients with polyps than in controls (P<0.0001) but less common than in gallstone patients (P<0.0001). Polyps and gallstones were associated with nonapolipoprotein E4 phenotypes. The natural history of small gallbladder polyps was benign, as no patient developed specific symptoms and/or morphological changes in polyps. Consequently, a "wait and see" policy is advisable in these patients. Polyps have some pathogenetic mechanisms in common with gallstones, but few patients developed gallstones.

Identification of Salmonella enterica Serovar Typhimurium Genes Regulated during Biofilm Formation on Cholesterol Gallstone Surfaces

PubMed Central

2013-01-01

Salmonella spp. are able to form biofilms on abiotic and biotic surfaces. In vivo studies in our laboratory have shown that Salmonella can form biofilms on the surfaces of cholesterol gallstones in the gallbladders of mice and human carriers. Biofilm formation on gallstones has been demonstrated to be a mechanism of persistence. The purpose of this work was to identify and evaluate Salmonella sp. cholesterol-dependent biofilm factors. Differential gene expression analysis between biofilms on glass or cholesterol-coated surfaces and subsequent quantitative real-time PCR (qRT-PCR) revealed that type 1 fimbria structural genes and a gene encoding a putative outer membrane protein (ycfR) were specifically upregulated in Salmonella enterica serovar Typhimurium biofilms grown on cholesterol-coated surfaces. Spatiotemporal expression of ycfR and FimA verified their regulation during biofilm development on cholesterol-coated surfaces. Surprisingly, confocal and scanning electron microscopy demonstrated that a mutant of type 1 fimbria structural genes (ΔfimAICDHF) and a ycfR mutant showed increased biofilm formation on cholesterol-coated surfaces. In vivo experiments using Nramp1+/+ mice harboring gallstones showed that only the ΔycfR mutant formed extensive biofilms on mouse gallstones at 7 and 21 days postinfection; ΔfimAICDHF was not observed on gallstone surfaces after the 7-day-postinfection time point. These data suggest that in Salmonella spp., wild-type type 1 fimbriae are important for attachment to and/or persistence on gallstones at later points of chronic infection, whereas YcfR may represent a specific potential natural inhibitor of initial biofilm formation on gallstones.

To study the changes of interstitial cells of Cajal (ICCs) and expression of c-kt and scf mRNA in terminal ileum tissue during cholesterol gallstone formation in guinea pigs fed on high cholesterol diet, forty guinea pigs were divided into the gallstone group and the control group. The animals in the gallstone group were fed on a high cholesterol diet (HCD), while those in the control group fed on a standard diet (StD). The guinea pigs were sacrificed at the 8th week. The expression of c-kit and scf in terminal ileum were determined by RT-PCR and the morphological characteristics and number of ICCs were observed and calculated by using immunohistochemistry. RT-PCR showed that, compared with the control group, the c-kit and scf mRNA expression levels in the gallstone group were significantly declined. In the animal assay, the decreased number of ICCs was present obviously in the gallstone group. We concluded from the study that decreased number of ICCs, decreased expression of c-kit and scf in terminal ileum are present in guinea pigs fed on high cholesterol diet. The c-kit/scf pathway inhibition might be involved in the decline of intestinal transit function during cholesterol gallstone formation. PMID:24995081

The Influence of Genetics on Cystic Fibrosis Phenotypes

PubMed Central

Knowles, Michael R.; Drumm, Mitchell

2012-01-01

Technological advances in genetics have made feasible and affordable large studies to identify genetic variants that cause or modify a trait. Genetic studies have been carried out to assess variants in candidate genes, as well as polymorphisms throughout the genome, for their associations with heritable clinical outcomes of cystic fibrosis (CF), such as lung disease, meconium ileus, and CF-related diabetes. The candidate gene approach has identified some predicted relationships, while genome-wide surveys have identified several genes that would not have been obvious disease-modifying candidates, such as a methionine sulfoxide transferase gene that influences intestinal obstruction, or a region on chromosome 11 proximate to genes encoding a transcription factor and an apoptosis controller that associates with lung function. These unforeseen associations thus provide novel insight into disease pathophysiology, as well as suggesting new therapeutic strategies for CF. PMID:23209180

Here, we report two patients with transomental hernia who were successfully treated with laparoscopic surgery. The first patient was a 58-year-old female who presented to our hospital with abdominal pain and vomiting; she had no history of abdominal surgery. Enhanced computed tomography revealed strangulation ileus due to an internal hernia. The second patient was a 36-year-old male who presented to our hospital with abdominal pain and no history of abdominal surgery. Enhanced computed tomography indicated transomental hernia. Emergency laparoscopic surgery in both patients revealed incarcerated bowel loops through defects in the greater omentum. The bowel segments were laparoscopically released, and the patients were uneventfully discharged on postoperative Days 4 and 8. Laparoscopic surgery is useful for the diagnosis and treatment of small bowel obstruction due to transomental hernia through the greater omentum.

The aim of this study was to investigate the epidemiologic characteristics and changing patterns of gallstone disease in Korea over a recent 20-year period. A total of 4020 gallstone patients who had undergone surgery at Seoul National University Hospital during 1981-2000 were analyzed according to periods: period I (1981-1985: 831 cases); period II (1986-1990: 888 cases); period III (1991-1995: 1040 cases); period IV (1996-2000: 1261 cases). The literature from 13 institutes in Korea reporting a total of 13,101 gallstone cases were reviewed to elucidate the nationwide trend. The number of gallstone cases gradually increased. A female predominance was not noted (F/M = 1.17-1.37) as is seen in Western countries. The patients with common bile duct (CBD) stones were older than those with gallbladder (GB) stones or intrahepatic duct (IHD) stones. Over time, the relative proportion of those with a GB stone increased, plateauing (80-85%) during the 1990s; that of patients with CBD stones decreased (34% --> 19%); and that of those with IHD stones remained unchanged (11-15%). Over the entire period, the rural pattern of gallstone formation (low number of GB stones, high numbers of CBD and IHD stones) has become similar to the urban pattern. The body mass index (BMI) of the GB stone group was above average, as were the BMIs of the CBD stone and IHD stone groups. Throughout the literature review, this same changing pattern of the relative proportion of gallstone disease was confirmed. Thus the pattern of gallstone disease in Korea has become similar to that seen in Western countries except for a high prevalence of hepatolithiasis.

To investigate whether screening for gallstone disease was economically feasible and clinically effective. This clinical study was initially conducted in 2002 in Taipei, Taiwan. The study cohort total included 2386 healthy adults who were voluntarily admitted to a regional teaching hospital for a physical check-up. Annual follow-up screening with ultrasound sonography for gallstone disease continued until December 31, 2007. A decision analysis using the Markov Decision Model was constructed to compare different screening regimes for gallstone disease. The economic evaluation included estimates of both the cost-effectiveness and cost-utility of screening for gallstone disease. Direct costs included the cost of screening, regular clinical fees, laparoscopic cholecystectomy, and hospitalization. Indirect costs represent the loss of productivity attributable to the patient's disease state, and were estimated using the gross domestic product for 2011 in Taiwan. Longer time intervals in screening for gallstone disease were associated with the reduced efficacy and utility of screening and with increased cost. The cost per life-year gained (average cost-effectiveness ratio) for annual screening, biennial screening, 3-year screening, 4-year screening, 5-year screening, and no-screening was new Taiwan dollars (NTD) 39076, NTD 58059, NTD 72168, NTD 104488, NTD 126941, and NTD 197473, respectively (P < 0.05). The cost per quality-adjusted life-year gained by annual screening was NTD 40725; biennial screening, NTD 64868; 3-year screening, NTD 84532; 4-year screening, NTD 110962; 5-year screening, NTD 142053; and for the control group, NTD 202979 (P < 0.05). The threshold values indicated that the ultrasound sonography screening programs were highly sensitive to screening costs in a plausible range. Routine screening regime for gallstone disease is both medically and economically valuable. Annual screening for gallstone disease should be recommended.

Infection is the most common cause of high morbidity, hospitalization, and mortality in children with sickle cell anemia. In this study of pediatric sickle cell anemia patients, aged 1 to 19, we explore the hypothesis that gallstones (usually pigment stones) create a nidus of infection, predisposing the affected patients to high morbidity. Our study involved 86 children with sickle cell anemia at the Howard University Center for Sickle Cell Disease, who had been followed at the clinic for a total of 602 patient years. Review of their records revealed that patients with gallstones had a mean number of 10.24 hospitalizations and 25.35 ambulatory visits; those without gallstones had a mean number of only 4.26 hospitalizations and 13.41 ambulatory visits. In children with sickle cell anemia and gallstones, elective cholecystectomy (or, in the future, cholelithotripsy) could reduce the high morbidity caused by infection. PMID:2213913

Complications caused by lost gallstones within the abdominal cavity are well known. Abscesses, perforation of the gastro-intestinal tract were all described in the literature, but gallstones were found in hernial sac, or even in sputum after it penetrated through the diaphragm into the respiratory tract. These complications can develop between several weeks to several years postoperatively. Most complications can be treated surgically only. Fifty gallstones and bile samples were collected from 50 patients who underwent cholecystectomy (36 female / 14 male, avarge age: 60.8 ± 6.8 years). All samples were sent for microbiological examination. bacterial colonization of the gallstone and the bile were found in 16 cases. Four of them showed acute inflammation in the gallbladder while pathological signs of chronic inflammation in the gallbladder wall were detected in eight cases. Empyema was found in four cases. Bacteria from enteral origin (Esherichia coli, Enterococcus faecalis, Enterobacter cloacae) was detected in 13 cases, while non-enteral (Klebsiella penumoniae, Streptococcus alfa-haemoliticus) colony were detected in three cases. Positive bacterial cultures were identified in twelve female and fourmale patients. Different types of bacteria can be found in the gallstones, which may cause various complications.

Background The aim of the study was to evaluate if the gallstone-related hospitalizations in the young (< 20 years of age) have increased over time in both the Bronx County and New York State as a whole. Methods We retrospectively reviewed 15 years (1996 - 2010) of Statewide Planning and Research Cooperative System (SPARCS) data of New York State Department of Health. Patients with ICD-9 code diagnosis of 574 (cholelithiasis) among the first three discharge diagnoses were reviewed. Results Total number of all cause admissions to hospitals had increased from 2.44 million to 2.77 million (1996 - 2010). However, gallstone-related hospitalizations had decreased from 1.7% to 1.2%. It was noted that there was a 30% increment in the proportion of those below 20 years of age with gallstone disease requiring hospitalization over the same period. This young patient population contributed only 2.04% to all gallstone-related hospitalizations in 1996, whereas it had increased to 2.96% in 2010. This trend was more pronounced in women, Hispanics and in those who were residing in the Bronx County as compared to all other New York counties combined. Conclusion The gallstone-related hospitalizations in the young (< 20 years of age) have increased over time in both the Bronx County and New York State as a whole. This could be due to increasing prevalence of risk factors such as obesity, physical inactivity, diabetes and early pregnancy. PMID:28090227

Cholesterol cholelithiasis is a multifactorial disease influenced by a complex interaction of genetic and environmental factors, and represents a failure of biliary cholesterol homeostasis in which the physical-chemical balance of cholesterol solubility in bile is disturbed. The primary pathophysiologic event is persistent hepatic hypersecretion of biliary cholesterol, which has both hepatic and small intestinal components. The majority of the environmental factors are probably related to Western-type dietary habits, including excess cholesterol consumption. Laparoscopic cholecystectomy, one of the most commonly performed surgical procedures in the US, is nowadays a major treatment for gallstones. However, it is invasive and can cause surgical complications, and not all patients with symptomatic gallstones are candidates for surgery. The hydrophilic bile acid, ursodeoxycholic acid (UDCA) has been employed as first-line pharmacological therapy in a subgroup of symptomatic patients with small, radiolucent cholesterol gallstones. Long-term administration of UDCA can promote the dissolution of cholesterol gallstones. However, the optimal use of UDCA is not always achieved in clinical practice because of failure to titrate the dose adequately. Therefore, the development of novel, effective, and noninvasive therapies is crucial for reducing the costs of health care associated with gallstones. In this review, we summarize recent progress in investigating the inhibitory effects of ezetimibe and statins on intestinal absorption and hepatic biosynthesis of cholesterol, respectively, for the treatment of gallstones, as well as in elucidating their molecular mechanisms by which combination therapy could prevent this very common liver disease worldwide.

Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal medicine, is prescribed for patients with postoperative ileus (POI) and adhesive bowel obstruction following abdominal surgery. Several mechanisms for the amelioration of POI by DKT have been suggested; however, it has remained unclear whether DKT shows anti-inflammatory effects in POI. In the present study, we investigated the effects of DKT in a mouse POI model and attempted to clarify the detailed mechanisms of action. Intestinal manipulation (IM) was applied to the distal ileum of mice. DKT was administered orally to the animals 4 times before and after IM. Gastrointestinal transit in vivo, leukocyte infiltration, cytokine mRNA expression and gastrointestinal motility were analyzed. We also investigated the effects of the α7nAChR antagonist methyllycaconitine citrate (MLA) on the DKT-mediated ameliorative action against POI, and we studied the effects of DKT on inflammatory activity in α7nAChR knockout mice. DKT treatment led to recovery of the delayed intestinal transit induced by IM. DKT significantly inhibited the infiltration of neutrophils and CD68-positive macrophages, and inhibited mRNA expressions of TNF-α and MCP-1. MLA significantly reduced the anti-inflammatory action of DKT, and the amelioration of macrophage infiltration by DKT was partially suppressed in α7nAChR knockout mice. In conclusion, in addition to the gastrointestinal prokinetic action, DKT serves as a novel therapeutic agent for POI characterized by its anti-inflammatory potency. The DKT-induced anti-inflammatory activity may be partly mediated by activation of α7nAChR.

The purpose of this study was to evaluate outcomes of the surgical management for meconium ileus (MI) and Distal Intestinal Obstruction Syndrome (DIOS) in Cystic Fibrosis (CF). Children born between 1990 and 2010 were identified using a regional CF database. Retrospective case note analysis was performed. Outcome measures for MI were mortality, relaparotomy rate, length of stay (LOS), time on parental nutrition (TP), and time to full feeds (TFF). Outcome measures for DIOS were: age of onset, number of episodes, and need for laparotomy. Seventy-five of 376 neonates presented with MI. Fifty-four (92%) required laparotomy. Contrast enema decompression was attempted in nineteen. There were no post-operative deaths. Thirty-nine (72%) neonates with MI were managed with stomas. LOS was longer in those managed with stomas (p=0.001) and in complex MI (p=0.002). Thirty-five patients were treated for DIOS. Twenty-five patients were managed with gastrograffin. Ten patients underwent surgical management of DIOS. Overall, MI did not predispose to later development of DIOS. There was a significantly greater incidence of laparotomy for DIOS in children who had MI. The proportion of neonates with complex meconium ileus was high (49%) and may explain the infrequent utilisation of radiological decompression. Complex MI or management with stomas both significantly increase LOS. Re-laparotomy rate is high (22%) in MI irrespective of the type of management. DIOS is not a benign condition, particularly when the child has had previous abdominal surgery. Early referral to a surgical team is essential in these children. Copyright © 2014 Elsevier Inc.

A 57year old male patient presented to the Emergency Clinic with abdominal pain, vomiting, constipation and lack of flatulence. The patient was taken to the operating room for emergency surgery with the diagnosis of intestinal obstruction. While still hospitalized, breast ultrasound was performed, revealing a mass lesion in the right breast measuring 2cm. The core biopsy result was suggestive of invasive ductal adenocarcinoma. Right modified radical mastectomy with removal of the level 2 axillary lymph nodes was performed. The result of the histopathological investigation of the right hemicolectomy specimen was reported as moderately differentiated adenocarcinoma, while that of the mastectomy material was invasive ductal adenocarcinoma. Synchronous colorectal cancer is recognized as an important clinical entity, its clinical and pathological properties as well as prognosis are still undetermined. A family history of cancer might be a significant factor in synchronous cancers. Many of the theories about the etiology of multiple primary malignant neoplasia suggest the role of genetic, hormonal, environmental and immunological factors as well as iatrogenic causes. Especially for patients whose treatment begins in the emergency settings, meticulous systemic physical examination is recommended to initiate treatment of a possible synchronous tumor at an earlier stage.

The article shows that the hardness salts contain the same crystalline phases as the bile stone pigment. The identity of EPR spectra of hardness salts and pigment of gallstones containing calcium carbonate was established. An analogy between the processes of formation of hardness salts and gallstones is played, in which particles with open spin-orbitals (fermions) play a decisive role.

Resolution of inflammation is an active counter-regulatory mechanism involving polyunsaturated fatty acid-derived proresolving lipid mediators. Postoperative intestinal motility disturbances, clinically known as postoperative ileus, occur frequently after abdominal surgery and are mediated by a complex inflammation of the intestinal muscularis externa. Herein, we tested the hypothesis that proresolving lipid mediators are involved in the resolution of postoperative ileus. In a standardized experimental model of postoperative ileus, we detected strong expression of 12/15-lipoxygenase within the postoperative muscularis externa of C57BL/6 mice, predominately located within CX3CR1(+)/Ly6C(+) infiltrating monocytes rather than Ly6G(+) neutrophils. Mass spectrometry analyses demonstrated that a 12/15-lipoxygenase increase was accompanied by production of docosahexaenoic acid-derived lipid mediators, particularly protectin DX and resolvin D2, and their common precursor 17-hydroxy docosahexaenoic acid. Perioperative administration of protectin DX, but not resolvin D2 diminished blood-derived leukocyte infiltration into the surgically manipulated muscularis externa and improved the gastrointestinal motility. Flow cytometry analyses showed impaired Ly6G(+)/Ly6C(+) neutrophil extravasation after protectin DX treatment, whereas Ly6G(-)/Ly6C(+) monocyte numbers were not affected. 12/15-lipoxygenase-deficient mice, lacking endogenous protectin DX synthesis, demonstrated increased postoperative leukocyte levels. Preoperative intravenous administration of a docosahexaenoic acid-rich lipid emulsion reduced postoperative leukocyte infiltration in wild-type mice but failed in 12/15-lipoxygenase-deficient mice mice. Protectin DX application reduced leukocyte influx and rescued 12/15-lipoxygenase-deficient mice mice from postoperative ileus. In conclusion, our results show that 12/15-lipoxygenase mediates postoperative ileus resolution via production of proresolving docosahexaenoic acid-derived protectin DX. Perioperative, parenteral protectin DX or docosahexaenoic acid supplementation, as well as modulation of the 12/15-lipoxygenase pathway, may be instrumental in prevention of postoperative ileus. © Society for Leukocyte Biology.

In recent years, some Chinese doctors have proposed a new concept, gallstone removal without gallbladder excision, along with transition of the medical model. As there is no specialized endoscope for gallstone removal without gallbladder excision, we designed and produced a new series of gallbladder endoscopes and accessories that have already been given a Chinese invention patent (No. ZL200810199041.2). The design of these gallbladder endoscopes was based on the anatomy and physiology of the gallbladder, characteristics of gallbladder disease, ergonomics, and industrial design. This series of gallbladder endoscopes underwent clinical trials in two hospitals appointed by the State Administration of Traditional Chinese Medicine. The clinical trials showed that surgeries of gallstones, gallbladder polyps, and cystic duct calculus could be smoothly performed with these products. In summary, this series of gallbladder endoscopes is safe, reliable, and effective for gallstone removal without gallbladder excision. This note comprehensively introduces the research and design of this series of gallbladder endoscopes.

Cholesterol gallstone disease is a common clinical condition influenced by genetic factors, increasing age, female gender, and metabolic factors. Although laparoscopic cholecystectomy is currently considered the gold standard in treating patients with symptomatic gallstones, new perspectives regarding medical therapy of cholelithiasis are currently under discussion, also taking into account the pathogenesis of gallstones, the natural history of the disease and the analysis of the overall costs of therapy. A careful selection of patients may lead to successful non-surgical therapy in symptomatic subjects with a functioning gallbladder harboring small radiolucent stones. The classical oral litholysis by ursodeoxycholic acid has been recently paralleled by new experimental observations, suggesting that cholesterol-lowering agents which inhibit cholesterol synthesis (statins) or intestinal cholesterol absorption (ezetimibe), or drugs acting on specific nuclear receptors involved in cholesterol and bile acid homeostasis, might be proposed as additional approaches for treating cholesterol gallstones. In this review we discuss old, recent and future perspectives on medical treatment of cholesterol cholelithiasis. PMID:22577615

Gallstones (GS) associated diseases are among the most recurrent and frequent diseases delineated in India and United Arab Emirates. Several reports suggest that the association of GS with gallbladder cancer (GBC) is very high in Northern part of India; however, its occurrence in UAE and Southern part of India is notably low. Therefore, in the present study, we aimed to perform compositional analysis of GS in three different geographical areas by Solid State Nuclear Magnetic Resonance and Fourier Transformed Infrared spectroscopy. Natural abundance 13C cross polarization magic angle spinning Nuclear Magnetic Resonance and Fourier Transform Infrared spectroscopy is employed for the analysis of human gallstone. Cholesterol, bilirubin and calcium carbonate were present in variant concentrations in GS obtained from three different geographical regions. Cholesterol was present predominantly in gallstones from North India. Bilirubin was found to be a main constituent in gallstones pertaining to South India. Whereas GS from UAE showed both cholesterol and bilirubin as their major constituents. Calcium carbonate was found in varying concentrations in gallstones acquired from different regions. Variation in environmental condition and dietary habits may contribute and affect the GS formation. Alterations in bile composition influence the GB and augment the crystallization of cholesterol. Analysis of different geographical regions GS could be an important stride to understand the etiology of GS diseases.

Since medical treatment of gallstones is confined to cholesterol-rich stones, the ability of clinical radiographs to predict gallstone type was tested prospectively by comparing the preoperative radiological appearance of gallstones from 57 unselected patients with cholelithiasis coming to cholecystectomy with the subsequent analysis of the stones both by X-ray diffraction and by chemical techniques. Fifty-two per cent of the patients had 'non-functioning' gallbladders which failed to opacify after at least two contrast examinations and 25 out of 50 had radioopaque stones. Of the 25 patients with radiolucent stones, the stones in 20 ((80%) were predominantly cholesterol in type but radiology was misleading in five; three contained 40-55% calcium salts but were still radiolucent while two were amorphous and contained less than 10% cholesterol by weight on chemical analysis. While radiology was sometimes misleading when the stones were small and irregular, large radiolucent stones with a smooth profile were invariably cholesterol-rich stones. The results also show that in men calcified stones were commoner than in women and that in older women the gallstones contained more calcium salts and less cholesterol than in younger women less than 50 yr). This paper analyses critically the value and limitations of clinical radiology in predicting gallstone type. PMID:1140634

Laser-induced breakdown spectroscopy (LIBS) is an emerging analytical technique with numerous advantages such as rapidity, multi-elemental analysis, no specific sample preparation requirements, non-destructiveness, and versatility. It has been proven to be a robust elemental analysis tool attracting interest because of being applied to a wide range of materials including biomaterials. In this paper, we have performed spectroscopic studies on gallstones which are heterogeneous in nature using LIBS and wavelength dispersive X-ray fluorescence (WD-XRF) techniques. It has been observed that the presence and relative concentrations of trace elements in different kind of gallstones (cholesterol and pigment gallstones) can easily be determined using LIBS technique. From the experiments carried out on gallstones for trace elemental mapping and detection, it was found that LIBS is a robust tool for such biomedical applications. The stone samples studied in the present paper were classified using the Fourier transform infrared (FTIR) spectroscopy. WD-XRF spectroscopy has been applied for the qualitative and quantitative analysis of major and trace elements present in the gallstone which was compared with the LIBS data. The results obtained in the present paper show interesting prospects for LIBS and WD-XRF to study cholelithiasis better.

Gallstone disease has been related to a higher prevalence and incidence of chronic conditions, such as dyslipidemia, obesity, and cardiovascular disease (CVD). However, limited data are available regarding whether gallstone disease is related to mortality. We examined the relationship of a history of gallstone disease and risk of death, using Cox proportional hazards regression analysis, among 86,030 women from the Nurses' Health Study and 43,949 men from the Health Professionals Follow-up Study. During the up-to 32 years of follow-up, 34,011 all-cause deaths were confirmed, of which 8138 were CVD deaths and 12,173 were cancer deaths. For the participants with a history of gallstone disease compared to those without, the hazard ratio of total mortality was 1.16 (95% confidence interval [CI] 1.13-1.20), of CVD mortality 1.11 (1.05-1.17), of cancer mortality 1.15 (1.09-1.20), and of other mortality 1.19 (1.14-1.25) from a pooled-analysis of women and men (all P < 0.001). The multi-adjusted associations between gallstone disease and total mortality persisted among women and men, and among participants with various risk profiles including the different status of body mass index, hormone therapy use, diabetes, hypertension and hypercholesterolemia (all P for interaction≥0.09). These data suggest that gallstone disease is associated with a higher risk of total mortality and disease-specific mortality, including CVD and cancer mortality, independent of various traditional risk factors.

Despite evidence that mucin overproduction is critical in the pathogenesis of gallstones, the mechanisms triggering mucin production in gallstone disease are unknown. Here, we tested the potential implication of an inflammation-dependent epidermal growth factor receptor (EGF-R) pathway in the regulation of gallbladder mucin synthesis. In gallbladder tissue sections from subjects with cholesterol gallstones, mucus accumulation was associated with neutrophil infiltration and with increased expressions of EGF-R and of tumor necrosis factor-α (TNF-α). In primary cultures of human gallbladder epithelial cells, TNF-α induced EGF-R overexpression. In the presence of TNF-α, EGF-R ligands (either EGF or transforming growth factor-α) caused significant increases in MUC5AC mRNA and protein production, whereas expression of the other gallbladder mucins MUC1, MUC3, and MUC5B was unchanged. In addition, on gallbladder tissue sections from subjects with gallstones, increased MUC5AC immunoreactivity was detected in the epithelium and within mucus gel in the lumen. Studies in primary cultures demonstrated that MUC5AC up-regulation induced by the combination of TNF-α with EGF-R ligands was completely blunted by inhibitors of EGF-R tyrosine kinase and mitogen-activated protein/extracellular signal-related kinase kinase. In conclusion, an inflammation-dependent EGF-R cascade causes overproduction of the gel-forming mucin MUC5AC, which accumulates in cholesterol gallstone disease. The ability to interrupt this cascade is of potential interest in the prevention of cholesterol gallstones. PMID:17148666

Gallstones and gallbladder polyps (GPs) are two major types of gallbladder diseases that share multiple common symptoms. However, their pathological mechanism remains largely unknown. The aim of our study is to identify gallstones and GPs related-genes and gain an insight into the underlying genetic basis of these diseases. We enrolled 7 patients with gallstones and 2 patients with GP for RNA-Seq and we conducted functional enrichment analysis and protein-protein interaction (PPI) networks analysis for identified differentially expressed genes (DEGs). RNA-Seq produced 41.7 million in gallstones and 32.1 million pairs in GPs. A total of 147 DEGs was identified between gallstones and GPs. We found GO terms for molecular functions significantly enriched in antigen binding (GO:0003823, P=5.9E-11), while for biological processes, the enriched GO terms were immune response (GO:0006955, P=2.6E-15), and for cellular component, the enriched GO terms were extracellular region (GO:0005576, P=2.7E-15). To further evaluate the biological significance for the DEGs, we also performed the KEGG pathway enrichment analysis. The most significant pathway in our KEGG analysis was Cytokine-cytokine receptor interaction (P=7.5E-06). PPI network analysis indicated that the significant hub proteins containing S100A9 (S100 calcium binding protein A9, Degree=94) and CR2 (complement component receptor 2, Degree=8). This present study suggests some promising genes and may provide a clue to the role of these genes playing in the development of gallstones and GPs.

Little data exist regarding the recurrence of pancreatitis in pediatric patients with gallstone pancreatitis awaiting cholecystectomy. This study evaluates the recurrence rate of pancreatitis after acute gallstone pancreatitis based on the timing of cholecystectomy in pediatric patients. A retrospective chart review of all patients admitted with gallstone pancreatitis from 2007 to 2015 was performed. Children were divided into the following five groups. Group 1 had surgery during the index admission. Group 2 had surgery within 2 wk of discharge. Group 3 had surgery between 2 and 6 wk postdischarge. Group 4 had surgery 6 wk after discharge, and group 5 patients had no surgery. The recurrence rates of pancreatitis were calculated for all groups. Forty-eight patients with gallstone pancreatitis were identified in this study. The 19 patients in group 1 had no recurrence of their pancreatitis. Of the remaining 29 patients, nine (31%) had recurrence of pancreatitis or required readmission for abdominal pain prior to their cholecystectomy. In group 2, two of the eight patients (25%) had recurrent pancreatitis. In group 3, three of eight patients (37.5%) developed recurrent pancreatitis. In group 4, three of five patients (60%), and in group 5, one of eight. No children in group 5 had demonstrable gallstones at presentation, only sludge in their gallbladder. Cholecystectomy during the index admission is associated with no recurrence or readmission for pancreatitis. Therefore, we recommend that cholecystectomy be performed after resolution of an episode of gallstone pancreatitis during index admission. Copyright © 2017 Elsevier Inc. All rights reserved.

Background Estrogen is an important risk factor for cholesterol cholelithiasis not only in women of childbearing age taking oral contraceptives and postmenopausal women undergoing hormone replacement therapy, but also in male patients receiving estrogen therapy for prostatic cancer. In women, hormonal changes occurring during pregnancy markedly increase the risk of developing gallstones. We investigated whether the potent cholesterol absorption inhibitor ezetimibe could prevent the formation of estrogen-induced cholesterol gallstones in mice. Design Following ovariectomy, female AKR mice were implanted subcutaneously with pellets releasing 17β-estradiol at 6 μg/day and fed a lithogenic diet supplemented with ezetimibe in doses of 0 or 8 mg/kg/day for 8 weeks. Cholesterol crystallization and gallstone prevalence, lipid concentrations and composition in bile, and biliary lipid output were analyzed by physical-chemical methods. Intestinal cholesterol absorption efficiency was determined by fecal dual-isotope ratio methods. Results Ezetimibe inhibited intestinal cholesterol absorption, while significantly reducing hepatic secretion of biliary cholesterol. Consequently, bile was desaturated through the formation of numerous unsaturated micelles and gallstones were prevented by ezetimibe in mice exposed to high doses of estrogen and fed the lithogenic diet. Ezetimibe did not influence mRNA levels of the classical estrogen receptors α (ERα) and ERβ, as well as a novel estrogen receptor the G protein-coupled receptor 30 (GPR30) in the liver. Conclusions Ezetimibe protects against the estrogen-mediated lithogenic actions on gallstone formation in mice. Our finding may provide an efficacious novel strategy for the prevention of cholesterol gallstones in high-risk subjects, especially those exposed to high levels of estrogen. PMID:25303682

Gallbladder cancer is common in north India. It is also a well established fact that gall bladder cancer is frequently associated with gallstone disease in north India, similar to reports from the West. The magnitude of the problem of gallbladder cancer in south India and its link to gallstone disease is not clearly established. The aim of the study was to determine retrospectively, the characteristics of individuals with GBC in south India and to determine its association with gallstone disease. Retrospective data was obtained from records of proven cases of gallbladder cancer and patients undergoing cholecystectomy for gallstone disease between Jan 2001 and Dec 2010. Data retrieved included age, gender, and clinical presentation, findings on imaging, histology and details of management. The number of proven cases of gallbladder cancer each year ranged from 8 to 17. There were 38 men and 23 women. Male female ratio was 1.6:1. There were more men in the successive decades. Right upper quadrant pain (42 %) followed by jaundice (27 %) and a presence of a palpable mass (12 %) were the common clinical presentation. Pre-operative diagnosis of gall bladder cancer was possible in 80 %. Twelve patients had co-existing gallstones (19.6 %). Forty patients (50 %) had stage IV disease; only 6 patients had Stage I operable disease (9.8 %). During the same time 758 patients had cholecystectomy for gallstone disease. Only one patient had an incidental gall bladder cancer, who had an extended cholecystectomy. Gallbladder cancer is uncommon in south India and its association with gallstone is also low.

In the United States, cholesterol stones account for 70% to 95% of adult gallstones and black pigment stones for most of the remainder. Calcium carbonate stones are exceptionally rare. A previous analysis of a small number of pediatric gallstones from the north of England showed a remarkably high prevalence of calcium carbonate stones. The aims of this study were to analyze a much larger series of pediatric gallstones from our region and to compare their chemical composition with a series of adult gallstones from the same geographic area. A consecutive series of gallbladder stones from 63 children and 50 adults from the north of England were analyzed in detail using Fourier transform infrared microspectroscopy. Demographic and clinical data were collected on all patients. The relative proportions of each major stone component were assessed: cholesterol, protein and calcium salts of bilirubin, fatty acids, calcium carbonate, and hydroxyapatite. Thirty-nine (78%) adults had typical cholesterol stones, 7 (14%) had black pigment bilirubinate stones, and only 2 (4%) had calcium carbonate stones. In contrast, 30 (48%) children had black pigment stones, 13 (21%) had cholesterol stones, 15 (24%) had calcium carbonate stones, 3 (5%) had protein dominant stones, and 2 (3%) had brown pigment stones. In children, cholesterol stones were more likely in overweight adolescent girls with a family history of gallstones, whereas black pigment stones were equally common in boys and girls and associated with hemolysis, parenteral nutrition, and neonatal abdominal surgery. Calcium carbonate stones were more common in boys, and almost half had undergone neonatal abdominal surgery and/or required neonatal intensive care. The composition of pediatric gallstones differs significantly from that found in adults. In particular, one quarter of the children in this series had calcium carbonate stones, previously considered rare. Geographic differences are not the major reason for the high prevalence of calcium carbonate gallstones in children.

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Introduction There is a high incidence of gallstones in the Chilean population. Presentation of case We report on a 57-year-old man who complained of abdominal pain in the right upper quadrant. Abdominal ultrasound indicated acute cholecystitis and a single, extremely large pear-shaped gallstone (16.8 cm long, and 7.8 cm at its widest point and 4.1 cm at its narrowest point). Its fresh weight (at operation) was 278.0 g and, after 4 years, its dry weight was 259.5 g. Emergency classical cholecystectomy was carried out successfully. Discussion and Conclusion We have been unable to find a report of a larger gallstone in the English or Spanish language medical literature. PMID:22096735

Background Organochlorine pesticides (OCPs) are one kind of persistent organic pollutants. Although they are reported to be associated with metabolic disorders, the underlying mechanism is unclear. We explored the association of OCPs with gallstone disease and its influence on hepatic lipid metabolism. Materials and Methods OCPs levels in omentum adipose tissues from patients with and without gallstone disease between 2008 and 2011 were measured by GC-MS. Differences of gene expression involved in hepatic lipid metabolism and hepatic lipids content were compared in liver biopsies between groups with high and low level of OCPs. Using HepG2 cell lines, the influence on hepatic lipid metabolism by individual OCP was evaluated in vitro. Results In all patients who were from non-occupational population, there were high levels of β-hexachlorocyclohexane (β-HCH) and p',p'-dichloroethylene (p',p'-DDE) accumulated in adipose tissues. Both β-HCH and p', p'-DDE levels were significantly higher in adipose tissues from patients with gallstone disease (294.3± 313.5 and 2222± 2279 ng/g of lipid) than gallstone-free controls (282.7± 449.0 and 2025±2664 ng/g of lipid, P< 0.01) and they were strongly related with gallstone disease (P for trend = 0.0004 and 0.0138). Furthermore, higher OCPs in adipose tissue led to increase in the expression of hepatic cholesterol transporters ABCG5 and G8 (+34% and +27%, P< 0.01) and higher cholesterol saturation index in gallbladder bile, and induced hepatic fatty acids synthesis, which was further confirmed in HepG2 cells. Conclusion OCPs might enhance hepatic secretion of cholesterol into bile via ABCG5/G8 which promoting gallstone disease as well as lipogenesis. PMID:27203212

Same-admission cholecystectomy is indicated after gallstone pancreatitis to reduce the risk of recurrent disease or other gallstone-related complications, but its impact on overall costs is unclear. This study analysed the cost-effectiveness of same-admission versus interval cholecystectomy after mild gallstone pancreatitis. In a multicentre RCT (Pancreatitis of biliary Origin: optimal timiNg of CHOlecystectomy; PONCHO) patients with mild gallstone pancreatitis were randomized before discharge to either cholecystectomy within 72 h (same-admission cholecystectomy) or cholecystectomy after 25-30 days (interval cholecystectomy). Healthcare use of all patients was recorded prospectively using clinical report forms. Unit costs of resources used were determined, and patients completed multiple Health and Labour Questionnaires to record pancreatitis-related absence from work. Cost-effectiveness analyses were performed from societal and healthcare perspectives, with the costs per readmission prevented as primary outcome with a time horizon of 6 months. All 264 trial participants were included in the present analysis, 128 randomized to same-admission cholecystectomy and 136 to interval cholecystectomy. Same-admission cholecystectomy reduced the risk of acute readmission for recurrent gallstone-related complications from 16·9 to 4·7 per cent (P = 0·002). Mean total costs from a societal perspective were €234 (95 per cent c.i. -1249 to 738) less per patient in the same-admission cholecystectomy group. Same-admission cholecystectomy was superior to interval cholecystectomy, with a societal incremental cost-effectiveness ratio of -€1918 to prevent one readmission for gallstone-related complications. In mild biliary pancreatitis, same-admission cholecystectomy was more effective and less costly than interval cholecystectomy. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

The role of physical activity in preventing gallstone disease independent of its effect on the body weight has not been well established. We performed a systematic review and meta-analysis of cohort and case-control studies to analyze this potential association. We searched PubMed and EMBASE to identify all published studies in English through April 2016. We pooled the relative risks (RRs) or odds ratios (ORs) and corresponding 95% confidence intervals (CIs) from individual studies using a random-effects model to investigate associations between physical activity and the risk of gallstone disease. A total of 16 studies comprising 19 independent reports of approximately 260,000 participants met the inclusion criteria, including 6 case-control studies and 13 cohort studies. In a pooled analysis of cohort studies, physical activity (in a comparison of the highest-level and the lowest-level groups) was associated with a reduced risk of gallstone disease (RR=0.85; 95% CI, 0.78-0.92; I=79.5%). For men, the RR was 0.76 (95% CI, 0.60-0.97), and for women, the RR was similar (RR=0.77; 95% CI, 0.66-0.91). In a dose-response analysis, the RR of gallstone disease was 0.87 (95% CI, 0.83-0.92; I=1.0%) per 20 metabolic equivalent-hours of recreational physical per week. In comparison, case-control studies yielded a stronger significant risk reduction for gallstone disease (OR=0.64; 95% CI, 0.46-0.90; I=76.6%). This study suggests an inverse association between physical activity and gallstone disease in both men and women; however, these findings should be interpreted cautiously because of study heterogeneity.

Postoperative ileus is a common problem with significant clinical and economic consequences. We hypothesized that Gastrografin may have therapeutic utility by accelerating the recovery of postoperative ileus after colorectal surgery. The aim of this trial was to study the impact of oral Gastrografin administration on postoperative prolonged ileus (PPI) after elective colorectal surgery. The main endpoint of this randomized, double-blinded, controlled trial was time of resolution of PPI. The secondary endpoints were overall hospital length of stay, time to start oral intake, time to first passage of flatus or stools, time of need of nasogastric tube, and need of parenteral nutrition. Included criteria were patients older than 18 years, operated for colonic neoplasia, inflammatory bowel disease, or diverticular disease. There were two treatments: Gastrografin administration and placebo. The sample size was calculated taking into account the average length of postoperative ileus after colorectal resection until tolerance to oral intake. Statistical analysis showed that 29 subjects in each group were needed. Twenty-nine patients per group were randomized. Groups were comparable for age, gender, ASA Physical Status Classification System, stoma construction, and surgical technique. No statistical differences were observed in mean time to resolution between the two groups, 9.1 days (CI 95%, 6.51-11.68) in Gastrografin group versus 10.3 days (CI 6.96-10.29) in Placebo group (P = 0.878). Even if not statistically significant, time of resolution of PPI, overall length of stay, time of need of nasogastric tube, and time to tolerance of oral intake were shorter in the G group. Gastrografin does not accelerate significantly the recovery of prolonged postoperative ileus after elective colorectal resection when compared with placebo. However, it seems to clinically improve all the analyzed variables.

Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

Intestinal manipulation (IM) during abdominal surgery triggers the influx of inflammatory cells, leading to postoperative ileus. Prevention of this local muscle inflammation, using intercellular adhesion molecule-1 (ICAM-1) and leukocyte function-associated antigen-1-specific antibodies, has been shown to shorten postoperative ileus. However, the therapeutic use of antibodies has considerable disadvantages. The aim of the current study was to evaluate the effect of ISIS-3082, a mouse-specific ICAM-1 antisense oligonucleotide, on postoperative ileus in mice. Mice underwent a laparotomy or a laparotomy combined with IM after treatment with ICAM-1 antibodies, 0.1-10 mg kg(-1) ISIS-3082, saline or ISIS-8997 (scrambled control antisense oligonucleotides, 1 and 3 mg kg(-1)). At 24 h after surgery, gastric emptying of a 99mTC labelled semi-liquid meal was determined using scintigraphy. Intestinal inflammation was assessed by myeloperoxidase (MPO) activity in ileal muscle whole mounts. IM significantly reduced gastric emptying compared to laparotomy. Pretreatment with ISIS-3082 (0.1-1 mg kg(-1)) as well as ICAM-1 antibodies (10 mg kg(-1)), but not ISIS-8997 or saline, improved gastric emptying in a dose-dependent manner. This effect diminished with higher doses of ISIS-3082 (3-10 mg kg(-1)). Similarly, ISIS-3082 (0.1-1 mg kg(-1)) and ICAM-1 antibodies, but not ISIS-8997 or higher doses of ISIS-3082 (3-10 mg kg(-1)), reduced manipulation-induced inflammation. Immunohistochemistry showed reduction of ICAM-1 expression with ISIS-3082 only. ISIS-3082 pretreatment prevents postoperative ileus in mice by reduction of manipulation-induced local intestinal muscle inflammation. Our data suggest that targeting ICAM-1 using antisense oligonucleotides may represent a new therapeutic approach to the prevention of postoperative ileus.

Recently introduced treatment alternatives for gallstones include peroral pharmacological chemolysis plus shock wave lithotripsy and percutaneous cholecystolithotomy. Herein we report on the treatment preferences of 23 patients with symptomatic gallstones and our initial experience with percutaneous cholecystolithotomy in 6 of these patients. All patients were rendered stone free after one procedure. Percutaneous cholecystolithotomy, which is applicable to all types of gallstones, is a safe, practical, low-morbidity alternative to cholecystectomy in selected patients.

Background/Aims Treatment for cholangitis without common bile duct (CBD) stones has not been established in patients with gallstones. We investigated the usefulness of endoscopic biliary drainage (EBD) without endoscopic sphincterotomy (EST) in patients diagnosed with gallstones and cholangitis without CBD stones by endoscopic retrograde cholangiopancreatography (ERCP) and intraductal ultrasonography (IDUS). Methods EBD using 5F plastic stents without EST was performed prospectively in patients with gallstones and cholangitis if CBD stones were not diagnosed by ERCP and IDUS. After ERCP, all patients underwent laparoscopic cholecystectomy. The primary outcomes were clinical and technical success. The secondary outcomes were recurrence rate of biliary events and procedure-related adverse events. Results Among 187 patients with gallstones and cholangitis, 27 patients without CBD stones according to ERCP and IDUS received EBD using 5F plastic stents without EST. The stents were maintained in all patients until laparoscopic cholecystectomy, and recurrence of cholangitis was not observed. After cholecystectomy, the stents were removed spontaneously in 12 patients and endoscopically in 15 patients. Recurrence of CBD stones was not detected during the follow-up period (median, 421 days). Conclusions EBD using 5F plastic stents without EST may be safe and effective for the management of cholangitis accompanied by gallstones in patients without CBD stones according to ERCP and IDUS.

Gallstone bacteria provide a reservoir for biliary infections. Slime production facilitates adherence, whereas beta-glucuronidase and phospholipase generate colonization surface. These factors facilitate gallstone formation, but their influence on infection severity is unknown. Two hundred ninety-two patients were studied. Gallstones, bile, and blood (as applicable) were cultured. Bacteria were tested for beta-glucuronidase/phospholipase production and quantitative slime production. Infection severity was correlated with bacterial factors. Bacteria were present in 43% of cases, 13% with bacteremia. Severe infections correlated directly with beta-glucuronidase/phospholipase (55% with vs 13% without, P < 0.0001), but inversely with slime production (55 vs 8%, slime <75 or >75, P = 0.008). Low slime production and beta-glucuronidase/phospholipase production were additive: Severe infections were present in 76% with both, but 10% with either or none (P < 0.0001). beta-Glucuronidase/phospholipase production facilitated bactibilia (86% with vs 62% without, P = 0.03). Slime production was 19 (+/-8) vs 50 (+/-10) for bacteria that did or did not cause bacteremia (P = 0.004). No bacteria with slime >75 demonstrated bacteremia. Bacteria-laden gallstones are biofilms whose characteristics influence illness severity. Factors creating colonization surface (beta-glucuronidase/phospholipase) facilitated bacteremia and severe infections; but abundant slime production, while facilitating colonization, inhibited detachment and cholangiovenous reflux. This shows how properties of the gallstone biofilm determine the severity of the associated illness.

Spontaneous cholecystocutaneous fistula (SCF) is a rare complication of neglected calculous biliary disease and also an extremely rare complication of gallbladder neoplasm. This pathology has become even rarer because of prompt diagnosis and expedient surgical intervention for gallstones. So far, there is one published report of a SCF due to gallbladder adenocarcinoma. We present the case of a woman aged 87 years, admitted to the Vth Department of Surgery, Clinical Municipal Hospital of Cluj-Napoca (Romania) for a tumoral mass located in the epigastrium. In the epigastrium, the patient had three skin orifices of about 1-2 mm each, through which purulent secretion occurred. The abdominal ultrasound highlighted a cholecystocutaneous fistula with the presence of a subcutaneous gallstone. Intraoperatively, we found a cholecystocutaneous fistula, a 1 cm subcutaneous gallstone, gallbladder with thickened walls containing a cylinder-shaped gallstone of 5÷3 cm. Fistulectomy, gallstones extraction and cholecystectomy were performed. The histopathological examination highlighted gallbladder adenocarcinoma. In conclusion, SCF can be the first significant manifestation of gallbladder cancer associated with neglected calculous biliary disease.

Although the auscultation of bowel sounds is considered an essential component of an adequate physical examination, its clinical value remains largely unstudied and subjective. The aim of this study was to determine whether an accurate diagnosis of normal controls, mechanical small bowel obstruction (SBO), or postoperative ileus (POI) is possible based on bowel sound characteristics. Prospectively collected recordings of bowel sounds from patients with normal gastrointestinal motility, SBO diagnosed by computed tomography and confirmed at surgery, and POI diagnosed by clinical symptoms and a computed tomography without a transition point. Study clinicians were instructed to categorize the patient recording as normal, obstructed, ileus, or not sure. Using an electronic stethoscope, bowel sounds of healthy volunteers (n = 177), patients with SBO (n = 19), and patients with POI (n = 15) were recorded. A total of 10 recordings randomly selected from each category were replayed through speakers, with 15 of the recordings duplicated to surgical and internal medicine clinicians (n = 41) blinded to the clinical scenario. The sensitivity, positive predictive value, and intra-rater variability were determined based on the clinician's ability to properly categorize the bowel sound recording when blinded to additional clinical information. Secondary outcomes were the clinician's perceived level of expertise in interpreting bowel sounds. The overall sensitivity for normal, SBO, and POI recordings was 32%, 22%, and 22%, respectively. The positive predictive value of normal, SBO, and POI recordings was 23%, 28%, and 44%, respectively. Intra-rater reliability of duplicated recordings was 59%, 52%, and 53% for normal, SBO, and POI, respectively. No statistically significant differences were found between the surgical and internal medicine clinicians for sensitivity, positive predictive value, or intra-rater variability. Overall, 44% of clinicians reported that they rarely listened to bowel sounds, whereas 17% reported that they always listened. Auscultation of bowel sounds is not a useful clinical practice when differentiating patients with normal versus pathologic bowel sounds. The listener frequently arrives at an incorrect diagnosis. If routine abdominal auscultation is to be continued, our findings emphasize the need for improvements in training and education as well as advancements in the understanding of the objective acoustical properties of bowel sounds.

This study aimed to determine the effect of gum chewing on the reduction of postoperative ileus and recovery after surgery. This study was conducted a randomized controlled trial in 60 patients who underwent colorectal surgery between November 2011 and December 2012. Patients in the experimental group chewed gum three times a day. The time of flatus and defecation, the time to start feeding, pain levels and time of discharge were monitored. Post-surgery results for gum-chewing were first flatus and defecation times and the time to start feeding was shorter; pain levels were lower on the 3rd - 5th days; patients were discharged in a shorter time post-surgery. Chewing gum is a simple intervention for reducing postoperative ileus after colorectal surgery. Further studies that examine the effectiveness of gum chewing on other surgical interventions in which the development risk of postoperative ileus should be performed. Copyright © 2016 Elsevier Ltd.

The last two decades have seen the emergence of significant evidence that has altered certain aspects of the management of acute pancreatitis. While most cases of acute pancreatitis are mild, the challenge remains in managing the severe cases and the complications associated with acute pancreatitis. Gallstones are still the most common cause with epidemiological trends indicating a rising incidence. The surgical management of acute gallstone pancreatitis has evolved. In this article, we revisit and review the methods in diagnosing acute pancreatitis. We present the evidence for the supportive management of the condition, and then discuss the management of acute gallstone pancreatitis. Based on the evidence, our local institutional pathways, and clinical experience, we have produced an outline to guide clinicians in the management of acute gallstone pancreatitis. PMID:29563826

To present the history of surgical gastroenterology in Perm krai. Narrative, historical, genetic, comparative and structural. In the early 20th century the main method of surgical treatment of peptic ulcer was gastroenteroanastomosis. A significant number of recurrences resulted to distal gastrectomy implementation in the 30s in the Clinic of hospital surgery of Perm medical institute, led by professor M.V. Shats. It was also performed in major cities of the region: Lysva, Kungur, Berezniki, Kizel, Osa. Treatment of ulcer perforation and bleeding was accomplished at the department of surgical diseases of pediatric faculty, led by Professor V. N. Repin. He also developed vagotomy and methods of diagnostics and treatment of diseases of operated stomach. Comorbidity was also researched. The combination of liver and biliary tract diseases was re- searched in the Hospital surgical clinic of Perm, initially led by Professor S. Yu. Minkin and then by academician E. A. Wagner (L. F. Palatova). The results of surgical treatment of cholelithiasis, depending on morphological and biochemical abnormali- ties in liver and chemical composition of gallstones were studied (L. P. Kotelnikova). Indications for surgery in cholelithiasis in conjunction with pathology of stomach, duodenum and liver were defined (A.V. Popov). The results of surgical treatment of biliary pancreatitis and cholangitis (L. B. Guschensky), and diseases of stomach, duodenum and pancreas with cholelithiasis were obtained (D.V. Shvarev). The priority trends of research of Perm scientists were treatment of post-resection syndrome, arteriomesen- terial obstruction, pathogenesis of gallstone disease and its combination with other disorders of the digestive system.

Black bile of melancholy or gallstones of biliary colics: historical perspectives on cholelithiasis.

Bielefeldt, Klaus

2014-11-01

Barely 130 years after its first description, cholecystectomies are among the most commonly performed surgeries in the USA. The success of this operation with subsequent technical improvements, such as laparoscopic approaches, caused a paradigm shift in the management of gallstone disease. However, symptoms persist in 10-40 % of successfully operated patients. Reviewing monographs, textbooks, and articles published during the last 300 years, several important factors emerge as likely contributors to limited or poor treatment responses. Early on, clinicians recognized that cholelithiasis is quite common and thus often an incidental finding, especially if patients present with vague or atypical symptoms. Consistent with these observations, patients with such atypical symptoms are less likely to benefit from cholecystectomy. Similarly, lasting improvements are more reliably seen in patients with symptoms of presumed biliary origin and documented gallstones compared to individuals without stones, an important point in view of increasing rates of surgery for biliary dyskinesia. While cholelithiasis can cause serious complications, the overall incidence of clinically relevant problems is so low that prophylactic cholecystectomy cannot be justified. This conclusion corresponds to epidemiologic data showing that the rise in elective cholecystectomies decreased hospitalizations due to gallstone disease, but was associated with a higher volume of postoperative complications, ultimately resulting in stable combined mortality due to gallstone disease and its treatment. These trends highlight the tremendous gains in managing gallstone disease, while at the same time reminding us that the tightening rather than expanding indications for cholecystectomy may improve outcomes.

To investigate the effects of alcohol, tobacco and caffeine consumption and of vegetarian diet on gallstone prevalence in an urban population sample. A total of 2417 individuals underwent ultrasound examination and completed a standardized questionnaire as part of the EMIL study. Statistical analysis of the data considered the known risk factors of age, female sex, BMI, positive family history and potential confounders, such as alcohol, caffeine and tobacco consumption and vegetarian diet using multiple logistic regression with variable selection. The prevalence of gallstones in the population sample was 8% (171 out of 2147). Findings of the study confirmed the classic risk factors of age, female sex, obesity and positive family history. After the variable selection of potential risk factors in a logistic regression that was adjusted for age, female sex, BMI and positive family history, the factors like tobacco [odds ratio (OR) 1.09, 95% confidence interval (CI): 0.76-1.56, P=0.64] and caffeine consumption (OR: 0.77, 95% CI: 0.42-1.42, P=0.40) as well as vegetarian diet (OR: 1.14, 95% CI: 0.39-3.35, P=0.81) had no effect on gallstone prevalence. A protective effect against development of gallstones was shown for alcohol consumption (OR: 0.67, 95% CI: 0.46-0.99, P=0.04). The factors like tobacco and caffeine consumption as well as vegetarian diet exerted no measurable effect on the prevalence of gallstones. A protective effect was found for alcohol consumption.

Gallstones and cholecystectomy may be related to digestive system cancer through inflammation, altered bile flux, and changes in metabolic hormone levels. Although gallstones are recognized causes of gallbladder cancer, associations with other cancers of the digestive system are poorly established. We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database (1992-2005), which includes 17 cancer registries that cover approximately 26% of the US population, to identify first primary cancers (n = 236,850) occurring in persons aged ≥66 years and 100,000 cancer-free population-based controls frequency-matched by calendar year, age, and gender. Odds ratios and 95% confidence intervals were calculated using logistic regression analysis, adjusting for the matching factors. Gallstones and cholecystectomy were associated with increased risk of noncardia gastric cancer (odds ratio (OR) = 1.21 (95% confidence interval (CI): 1.11, 1.32) and OR = 1.26 (95% CI: 1.13, 1.40), respectively), small-intestine carcinoid (OR = 1.27 (95% CI: 1.01, 1.60) and OR = 1.78 (95% CI: 1.41, 2.25)), liver cancer (OR = 2.35 (95% CI: 2.18, 2.54) and OR = 1.26 (95% CI: 1.12, 1.41)), and pancreatic cancer (OR = 1.24 (95% CI: 1.16, 1.31) and OR = 1.23 (95% CI: 1.15, 1.33)). Colorectal cancer risk associated with gallstones and cholecystectomy decreased with increasing distance from the common bile duct (P-trend < 0.001). Hence, gallstones and cholecystectomy are associated with the risk of cancers occurring throughout the digestive tract.

Cholelithiasis is a common medical condition whose incidence rate is increasing yearly, while its pathogenesis has yet to be elucidated. The present study assessed the expression of Rho-kinase (ROCK) in gallbladder smooth muscles and its effect on the contractile function of gallbladder smooth muscles during gallstone formation. Thirty male guinea pigs were randomly divided into three groups: The control group, the gallstone model group and the fasudil interference group. The fasting volume (FV) and bile capacity of the gallbladder (FB) as well as the total cholesterol (TC) and triglyceride (TG) contents of the gallbladder bile were determined. In addition, the gallbladder was dissected to identify whether any gallstones had formed. Part of the gallbladder tissue specimens were used for immunohistochemical analysis of ROCK expression in gallbladder smooth muscles. The results showed that four guinea pigs in the model group and eight in the fasudil group displayed gallstone formation, while there was no gallstone formation in the control group. The FV and FB were significantly increased in the model and fasudil groups. Similarly, the TC and TG contents of gallbladder bile were increased in these groups. The positive expression rate of ROCK in gallbladder smooth muscles in the model and fasudil groups was significantly reduced compared with that in the control group (P<0.05). The results of the present study indicated that the reduction of ROCK expression in guinea pig gallbladder smooth muscles weakened gallbladder contraction and thereby promoted gallstone formation.

Because of the strong association between gallstones and biliary tract cancer, we conducted a case-control study of gallstones at Niigata Cancer Center Hospital. Eighty-six cases with gallstones (33 males and 53 females) and 116 hospital controls (56 males and 60 females) were surveyed by means of a self-administered questionnaire. Gallstones were categorized into cholesterol stones (25 cases) and pigment stones (30 cases) based on the appearance of the stones. In multivariate analyses based on an unconditional logistic regression model, the risk of total gallstones was positively associated with a taste for salty food (relative risk (RR) = 2.31, 95% confidence interval (CI): 1.10-4.84), an intake of lettuce and cabbage (RR = 2.98, 95% CI: 1.47-6.06) and a family history of biliary diseases (RR = 5.63, 95% CI: 1.76-17.95), and inversely associated with an intake of salted and dried fish (RR = 0.16, 95% CI: 0.04-0.64). When analyzed by type of stones, cholesterol stones were associated with a taste for oily food (RR = 3.87, 95% CI: 1.36-11.03) and pigment stones were positively associated with professional or administrative occupation (RR = 4.74, 95% CI: 1.35-16.68) and inversely associated with a taste for less greasy food (RR = 0.28, 95% CI: 0.10-0.83). Some of these results are consistent with the results of our previous study on biliary tract cancer.

Management of paediatric liver trauma.

2017-04-01

Of all the intra-abdominal solid organs, the liver is the most vulnerable to blunt abdominal trauma. The majority of liver ruptures present in combination with other abdominal or extra-abdominal injuries. Over the last three decades, the management of blunt liver trauma has evolved from obligatory operative to non-operative management in over 90% of cases. Penetrating liver injuries more often require operative intervention and are managed according to adult protocols. The greatest clinical challenge remains the timely identification of the severely damaged liver with immediate and aggressive resuscitation and expedition to laparotomy. The operative management can be taxing and should ideally be performed in a dedicated paediatric surgical centre with experience in dealing with such trauma. Complications can occur early or late and include haemobilia, intrahepatic duct rupture with persistent biliary fistula, bilaemia, intrahepatic haematoma, post-traumatic cysts, vascular outflow obstruction, and gallstones. The prognosis is generally excellent.

To detect the expression of pituitary adenylate cyclase-activating polypeptide receptor 1 (VPCAP1-R)and VPCAP2-R mRNA in gallbladder tissues of patients with gallstone or gallbladder polyps. The expression of VPCAP1-R and VPCAP2-R mRNA in gallbladder tissues was detected in 25 patients with gallstone,8 patients with gallbladder polyps and 7 donors of liver transplantation by reverse transcription polymerase chain reaction (RT-PCR). The VPCAP2-R mRNA expression level in the control group (1.09+/-0.58) was lower than that in the gallbladder polyp group (1.64+/-0.56) and the gallstone group (1.55+/-0.45) (P<0.05) while the VPCAP1-R mRNA expression level in the control group (1.15+/-0.23) was not apparently different from that in the gallbladder polyp group (1.28+/-0.56) and the gallstone group (1.27+/-0.38). The abnormal expression of VPCAP2-R mRNA in gallbladder tissue may play a role in the formation of gallbladder stone and gallbladder polyps.

Epidemiology of Gallbladder Disease: Cholelithiasis and Cancer

PubMed Central

Stinton, Laura M.

2012-01-01

Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.

Chronic application of third generation progestagens as contraceptives or hormone replacement therapy (HRT) could influence the serum lipid profile, and consequently the bile and gallstone composition. The aim of this study was to determine components of serum, bile and gallstones in women of reproductive age or postmenopausal women using hormonal third generation for at least two years. We enrolled 101 Caucasian women with cholelithiasis. The study included 45 women of reproductive age and 56 postmenopausal women who were divided into subgroups receiving or not exogenous female hormones. In patients we determined serum levels of 17β-estradiol, triglycerides, HDL and LDL cholesterol as well as composition of gallstones and bile. The postmenopausal women showed a significant reduction in the concentration of bile acids in serum while the application of HRT caused an increase in their contents. Serum total and LDL cholesterol in postmenopausal women was higher than in women without hormonal contraception and postmenopausal patients with HRT. Moreover, women taking the exogenous hormones showed a reduced content of calcium ions in both serum, bile and gallstones. Our observations confirm that the chronic use of oral contraceptives and hormone replacement therapy cause an increase in bile lithogenity.

[Purpose] This study investigated the serologic factors associated with metabolic syndrome and gallstones. [Subjects and Methods] The study evaluated subjects who visited a health promotion center in Seoul from March 2, 2013 to February 28, 2014, and had undergone abdominal ultrasonography. Height, weight, and blood pressure were measured. Blood sampling was performed for high-density lipoprotein cholesterol, triglyceride, fasting blood glucose, total bilirubin, direct bilirubin, indirect bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, uric acid, total cholesterol, low-density lipoprotein cholesterol, thyroid stimulating hormone, and red and white blood cell counts. We conducted logistic regression analysis to assess the risk factors associated with metabolic syndrome. [Results] The risk factors for metabolic syndrome in men, in order of decreasing weight, were red blood cell count, body mass index, maximum size of gallstones, white blood cell count, waist circumference, and uric acid level. The factors in women, in order of decreasing weight, were red blood cell count, presence/absence of gallstones, uric acid level, body mass index, fasting blood glucose, and waist circumference. [Conclusion] Most serum biochemical factors and gallstone occurrence could be used to indicate the presence or absence of metabolic syndrome, independent of gender. PMID:27630427

Intestinal manipulation (IM) during abdominal surgery triggers the influx of inflammatory cells, leading to postoperative ileus. Prevention of this local muscle inflammation, using intercellular adhesion molecule-1 (ICAM-1) and leukocyte function-associated antigen-1-specific antibodies, has been shown to shorten postoperative ileus. However, the therapeutic use of antibodies has considerable disadvantages. The aim of the current study was to evaluate the effect of ISIS-3082, a mouse-specific ICAM-1 antisense oligonucleotide, on postoperative ileus in mice. Mice underwent a laparotomy or a laparotomy combined with IM after treatment with ICAM-1 antibodies, 0.1–10 mg kg−1 ISIS-3082, saline or ISIS-8997 (scrambled control antisense oligonucleotides, 1 and 3 mg kg−1). At 24 h after surgery, gastric emptying of a 99mTC labelled semi-liquid meal was determined using scintigraphy. Intestinal inflammation was assessed by myeloperoxidase (MPO) activity in ileal muscle whole mounts. IM significantly reduced gastric emptying compared to laparotomy. Pretreatment with ISIS-3082 (0.1–1 mg kg−1) as well as ICAM-1 antibodies (10 mg kg−1), but not ISIS-8997 or saline, improved gastric emptying in a dose-dependent manner. This effect diminished with higher doses of ISIS-3082 (3–10 mg kg−1). Similarly, ISIS-3082 (0.1–1 mg kg−1) and ICAM-1 antibodies, but not ISIS-8997 or higher doses of ISIS-3082 (3–10 mg kg−1), reduced manipulation-induced inflammation. Immunohistochemistry showed reduction of ICAM-1 expression with ISIS-3082 only. ISIS-3082 pretreatment prevents postoperative ileus in mice by reduction of manipulation-induced local intestinal muscle inflammation. Our data suggest that targeting ICAM-1 using antisense oligonucleotides may represent a new therapeutic approach to the prevention of postoperative ileus. PMID:15997238

Distal intestinal obstruction syndrome (DIOS) and constipation in cystic fibrosis (CF) are conditions associated with impaction and/or obstruction by abnormally viscid mucofaecal material within the intestinal lumen. Dehydration has been proposed as a risk factor for DIOS and constipation in CF. The study primarily aimed to determine whether warmer ambient temperature and lower rainfall are risk factors for DIOS and constipation in CF. Hospitalisations for DIOS (incomplete or complete) and/or constipation were retrospectively identified (2000-2012). Genotype, phenotype, temperatures and rainfall data (for the week preceding and season of hospitalisation) were collected. Twenty-seven DIOS (59.3% incomplete; 40.7% complete) and 44 constipation admissions were identified. All admitted patients were pancreatic insufficient. Meconium ileus was significantly more likely in DIOS than constipation (64.7% vs. 33.3%; P = 0.038) and in complete than incomplete DIOS (100% vs. 57.1%; P = 0.04). The maximum temperature of the week before DIOS admission (mean (standard deviation) = 28.0 (5.8) °C) was significantly higher than the maximum temperature of the season of admission (25.2 (3.4) °C; P = 0.002). Similarly, the maximum temperature of the week before hospitalisation for constipation (mean (standard deviation) = 27.9 (6.3) °C) was significantly warmer compared with the season of admission (24.0 (4.1) °C; P < 0.0001). There were no significant differences between levels of rainfall during the week before hospitalisation and the season of admission for both DIOS and constipation. Relatively high ambient temperature may play a role in the pathogenesis of DIOS and constipation in CF. © 2016 The Authors Journal of Paediatrics and Child Health © 2016 Paediatrics and Child Health Division (Royal Australasian College of Physicians).

Prior studies indicate a possible association between depression and cholecystectomy, but no study has compared the risk of post-operative depressive disorders (DD) after cholecystectomy. This retrospective follow-up study aimed to examine the relationship between cholecystectomy and the risk of DD in patients with gallstones in a population-based database. Using ambulatory care data from the Longitudinal Health Insurance Database 2000, 6755 patients who received a first-time principal diagnosis of gallstones at the emergency room (ER) were identified. Among them, 1197 underwent cholecystectomy. Each patient was then individually followed-up for two years to identify those who were later diagnosed with DD. Cox proportional hazards regressions were performed to estimate the risk of developing DD between patients with gallstone who did and those who did not undergo cholecystectomy. Of 6755 patients with gallstones, 173 (2.56%) were diagnosed with DD during the two-year follow-up. Among patients who did and those who did not undergo cholecystectomy, 3.51% and 2.36% later developed depressive disorder, respectively. After adjusting for the patient's sex, age and geographic location, the hazard ratio (HR) of DD within two years of gallstone diagnosis was 1.43 (95% CI, 1.02-2.04) for patients who underwent cholecystectomy compared to those who did not. Females, but not males, had a higher the adjusted HR of DD (1.61; 95% CI, 1.08-2.41) for patients who underwent cholecystectomy compared to those who did not. There is an association between cholecystectomy and subsequent risk of DD among females, but not in males.

We have analyzed gallstones from four patients of Europe and particularly from England (including samples from a mother and a daughter) and Greece. According to the XRD, FTIR, NMR and laser micro-Raman results the studied materials correspond to typical cholesterol monohydrate (ChM). The micro-morphology of cholesterol microcrystals was investigated by means of SEM-EDS. The XRF results revealed that Ca is the dominant non-organic metal in all gallstones (up to ∼1.95wt.%) together with Fe, Cu, Pb and Ni (up to ~19ppm for each metal). Gallstones from England contain additional Mn (up to ~87ppm) and Zn (up to ∼6ppm) while the sample of the mother contains negligible Zn and Mn, compared to that of her daughter, but significant As (~4.5ppm). All cholesterol gallstones examined are well enriched in potentially toxic metals (Pb, as well as Ni in one case) and metalloids (As also in one case) as compared to the global average. The position of Zn, which is a characteristic biometal, in the structure of cholesterol, was investigated by molecular simulation using the Accelrys Materials Studio(®) software. On the basis of IRMS results, all gallstones examined exhibit a very light δ(13)C signature (average δ(13)C ~-24‰ PDB). Gamma-ray spectrometry measurements indicate the presence of (214)Pb and (214)Bi natural radionuclides due to the (238)U series as well as an additional amount of (40)K.

Chronic carriage of Salmonella Typhi is mediated primarily through the formation of bacterial biofilms on the surface of cholesterol gallstones. Biofilms, by definition, involve the formation of a bacterial community encased within a protective macromolecular matrix. Previous work has demonstrated the composition of the biofilm matrix to be complex and highly variable in response to altered environmental conditions. Although known to play an important role in bacterial persistence in a variety of contexts, the Salmonella biofilm matrix remains largely uncharacterized under physiological conditions. Initial attempts to study matrix components and architecture of the biofilm matrix on gallstone surfaces were hindered by the auto-fluorescence of cholesterol. In this work we describe a method for sectioning and direct visualization of extracellular matrix components of the Salmonella biofilm on the surface of human cholesterol gallstones and provide a description of the major matrix components observed therein. Confocal micrographs revealed robust biofilm formation, characterized by abundant but highly heterogeneous expression of polysaccharides such as LPS, Vi and O-antigen capsule. CsgA was not observed in the biofilm matrix and flagellar expression was tightly restricted to the biofilm-cholesterol interface. Images also revealed the presence of preexisting Enterobacteriaceae encased within the structure of the gallstone. These results demonstrate the use and feasibility of this method while highlighting the importance of studying the native architecture of the gallstone biofilm. A better understanding of the contribution of individual matrix components to the overall biofilm structure will facilitate the development of more effective and specific methods to disrupt these bacterial communities.

AIM: To detect the expression of pituitary adenylate cyclase-activating polypeptide receptor 1 (VPCAP1-R) and VPCAP2-R mRNA in gallbladder tissues of patients with gallstone or gallbladder polyps. METHODS: The expression of VPCAP1-R and VPCAP2-R mRNA in gallbladder tissues was detected in 25 patients with gallstone, 8 patients with gallbladder polyps and 7 donors of liver transplantation by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: The VPCAP2-R mRNA expression level in the control group (1.09±0.58) was lower than that in the gallbladder polyp group (1.64 ± 0.56) and the gallstone group (1.55±0.45) (P < 0.05) while the VPCAP1-R mRNA expression level in the control group (1.15 ± 0.23) was not apparently different from that in the gallbladder polyp group (1.28±0.56) and the gallstone group (1.27 ± 0.38). CONCLUSION: The abnormal expression of VPCAP2-R mRNA in gallbladder tissue may play a role in the formation of gallbladder stone and gallbladder polyps. PMID:16552823

During laparoscopic cholecystectomy, perforation of the gallbladder can occurs in < or = 20% of cases, while gallstone spillage occurs in < or = 6% of cases. In most cases, there are no consequences. Gallstones can be lost in the abdominal wall as well as the abdomen during extraction of the gallbladder. The fate of such lost gallstones, which can lead to the formation of an abscess, an abdominal wall mass, or a persistent sinus, has not been studied adequately. Herein we report the case of a persistent sinus of the abdominal wall after an emergent laparoscopic cholecystectomy in an 82-year-old woman with gangrenous cholecystitis and perforation of the friable wall in association with an empyema of the gallbladder. The culture of the obtained pus was positive for Escherichia coli. After a small leak of dirty fluid from the wound of the epigastric port site of 4 months' duration, surgical exploration under local anesthesia revealed that the sinus was caused by spilled gallstones impacting into the abdominal wall between the posterior sheath and left rectus abdominalis muscle. The removal of the stones resulted in complete healing. Long-term complications after laparoscopic cholecystectomy involving the abdominal wall are rare but important possible consequences that could be avoided.

Objective To describe an increased incidence and severity of gallstone pancreatitis in males compared to females. Design: Methods This is a retrospective observational comparative study conducted at Liaquat University of Medical and Health Sciences, Jamshoro, Pakistan, over 3 years from June 2008 to June 2011. The study includes two hundred and thirty seven (237) patients with a mean age of 52.38, Std 13.311,65 (22–87) with 157 (66.24%) females and 80 (33.75%) males who were admitted as acute abdominal pain secondary to gallstones. The patients were mostly diagnosed on ultrasonography and enzyme studies. Demographics and other variables are studied and statistical analysis done on SPSS version 20. Results More frequent cases of severe acute pancreatitis were observed in males with gallstones (70%) compared to females (P<0.001). The aged people had a high prevalence while males were more likely to develop local and systemic complications. Severity stratification was done based on different criteria’s like Ranson’s criteria, and APACHEII. Overall mortality was 7.59%. Mortality among males was significantly high (70%, n=16) in our study due to an increased incidence of fulminant course of the disease. Conclusion Contrary to the belief, gallstone associated acute pancreatitis is getting more common in our society and especially so in male population. PMID:26309432

In Mexico, Raphanus sativus L. var. niger (black radish) has uses for the treatment of gallstones and for decreasing lipids serum levels. We evaluate the effect of juice squeezed from black radish root in cholesterol gallstones and serum lipids of mice. The toxicity of juice was analyzed according to the OECD guidelines. We used female C57BL/6 mice fed with a lithogenic diet. We performed histopathological studies of gallbladder and liver, and measured concentrations of cholesterol, HDL cholesterol and triglycerides. The juice can be considered bioactive and non-toxic; the lithogenic diet significantly induced cholesterol gallstones; increased cholesterol and triglycerides levels, and decreased HDL levels; gallbladder wall thickness increased markedly, showing epithelial hyperplasia and increased liver weight. After treatment with juice for 6 days, cholesterol gallstones were eradicated significantly in the gallbladder of mice; cholesterol and triglycerides levels decreased too, and there was also an increase in levels of HDL (P < 0.05). Gallbladder tissue continued to show epithelial hyperplasia and granulocyte infiltration; liver tissue showed vacuolar degeneration. The juice of black radish root has properties for treatment of cholesterol gallstones and for decreasing serum lipids levels; therefore, we confirm in a preclinical study the utility that people give it in traditional medicine.

In seeking to identify nucleating/antinucleating proteins involved in the pathogenesis of cholesterol gallstones, a major acidic protein was isolated from each of 13 samples of cholesterol gallstones. After the stones were extracted with methyl t-butyl ether to remove cholesterol, and methanol to remove bile salts and other lipids, they were demineralized with EDTA. The extracts were desalted with Sephadex-G25, and the proteins separated by PAGE. A protein was isolated, of molecular weight below 10 kD, which included firmly-bound diazo-positive yellow pigments and contained 24% acidic, but only 7% basic amino acid residues. The presence of N-acetyl glucosamine suggested that this was a glycoprotein. This protein at concentrations as low as 2 micrograms/ml, but neither human serum albumin nor its complex with bilirubin, inhibited calcium carbonate precipitation from a supersaturated solution in vitro. This protein could be precipitated from 0.15 M NaCl solution by the addition of 0.5 M calcium chloride. Considering that cholesterol gallstones contain calcium and pigment at their centers, and that small acidic proteins are important regulators in other biomineralization systems, this protein seems likely to play a role in the pathogenesis of cholesterol gallstones.

[Preoperative fasting and fluid management in pediatric patients].

Preoperative fasting is principally intended to minimize the risk of pulmonary aspiration of gastric contents and facilitate the safe and efficient conduct of anesthesia. Liberalization of fasting guidelines has been implemented in most countries. In general, clear fluids are allowed up to 2h before anesthesia, and light meals up to 6h. In infants, most recommendations now allow breast milk feeding up to 4h and other kinds of milk up to 6h. Recently, the concept of preoperative oral rehydration using a carbohydrate-rich beverage up to 2h has also gained support. Drinking carbohydrate-rich fluids before elective surgery may reduce dehydration, improve hemodynamic stability under anesthesia, facilitate intravenous access, maintain glucose homeostasis, reduce patient irritability, and improve child and parent satisfaction. These guidelines apply to healthy children only. Exclusion criteria included obesity, diabetes, gastroesophageal reflux, ileus, bowel obstruction and emergency care. In particular, trauma and other emergency cases are at higher risk for aspiration regardless of fasting interval and should be managed appropriately.

2018-04-01

Gastrointestinal (GI) motility disorders are common in children. Treatment is challenging with limited medical and surgical options. Pyridostigmine, an acetyl cholinesterase inhibitor, increases acetylcholine at the neuromuscular junction promoting intestinal contractions. Little is known about the role and dosing of pyridostigmine in pediatric GI motility disorders. We present a case series of children with GI dysmotility managed with oral pyridostigmine. Patients' diagnoses include chronic intestinal pseudo-obstruction, gastroparesis with delayed small bowel transit, chronic constipation with failure to thrive, and prolonged ileus after pelvic surgery with chronic opioid use. Pyridostigmine was effective and safe in all cases. Pyridostigmine decreased abdominal distention, increased bowel movement frequency, and improved enteral feeding tolerance. Effective dosing ranged between 0.25-2.0 mg/kg/day. One patient experienced cramping abdominal pain while on pyridostigmine, but pain resolved after medication was discontinued. We found oral pyridostigmine to be helpful in children with different GI motility problems. Pyridostigmine should be considered in such patients when other treatment interventions have not been beneficial.

Bifidobacterium breve is an effective probiotic agent used in the field of neonatology. Although B. breve has been considered safe, a case of B. breve bacteremia has been reported. The pathogenic mechanism underlying the bacteremia is unknown. Herein, we report a second case of B. breve bacteremia that developed in a neonate with multiple abdominal organ anomalies. Following surgical repair immediately after birth, B. breve treatment was started. After 1 week, the infant developed B. breve bacteremia following the onset of adhesive ileus. The bacteremia was thought to have been associated with an intestinal obstruction. A pediatric culture bottle is theoretically unsuitable for incubating B. breve because B. breve is an obligate anaerobic bacterium. It was, however, cultured from pediatric culture bottles in the present case, suggesting that pediatric culture bottles may be useful for procuring B. breve and for determining antimicrobial susceptibility for screening purposes in neonatal patients. © 2016 Japan Pediatric Society.

2015-01-01

The formation of a bezoar is a relatively infrequent disorder that affects the gastrointestinal system. Bezoars are mainly classified into four types depending on the material constituting the indigestible mass of the bezoar: phytobezoars, trichobezoars, pharmacobezoars, and lactobezoars. Gastric bezoars often cause ulcerative lesions in the stomach and subsequent bleeding, whereas small intestinal bezoars present with small bowel obstruction and ileus. A number of articles have emphasized the usefulness of Coca-Cola® administration for the dissolution of phytobezoars. However, persimmon phytobezoars may be resistant to such dissolution treatment because of their harder consistency compared to other types of phytobezoars. Better understanding of the etiology and epidemiology of each type of bezoar will facilitate prompt diagnosis and management. Here we provide an overview of the prevalence, classification, predisposing factors, and manifestations of bezoars. Diagnosis and management strategies are also discussed, reviewing mainly our own case series. Recent progress in basic research regarding persimmon phytobezoars is also briefly reviewed.

We studied gallbladder bile flow before, during, and after cholesterol gallstone formation in the prairie dog using infusion cholescintigraphy with /sup 99m/Tc-diethyl iminodiacetic acid. In 18 fasting animals partitioning of bile between gallbladder and intestine was determined every 15 min for 140 min, and gallbladder response to cholecystokinin (5 U/kg X h) was calculated from the gallbladder ejection fraction. Ten prairie dogs were then placed on a 0.4% cholesterol diet and 8 on a regular diet, and the studies were repeated 1, 2, and 6 wk later. The proportion of hepatic bile that entered the gallbladder relative to the intestinemore » varied from one 15-min period to the next, and averaged 28.2% +/- 5.1% at 140 min. Partial spontaneous gallbladder emptying (ejection fraction 11.5% +/- 5.6%) was intermittently observed. Neither the number nor the ejection fraction of spontaneous gallbladder contractions changed during gallstone formation. By contrast, the percent of gallbladder emptying in response to cholecystokinin decreased from 72.1% +/- 5% to 25.9% +/- 9.3% (p less than 0.025) in the first week and was 14.3% +/- 5.5% at 6 wk (p less than 0.01 from prediet values, not significant from first week). Gallbladder filling decreased from 28.2% +/- 5.1% to 6.7% +/- 3% (p less than 0.01), but this change was only observed after 6 wk, when gallstones had formed. This study shows that bile flow into the gallbladder during fasting is not constant; the gallbladder contracts intermittently; gallbladder emptying in response to exogenous cholecystokinin is altered very early during gallstone formation; and gallbladder filling remains unaffected until later stages, when gallstones have formed.« less

Risk factors for gallbladder cancer (GBC) except gallstones are not well known. The objective was to study the risk factors for GBC. In a case-control study, 200 patients with GBC, 200 healthy controls and 200 gallstones patients as diseased controls were included prospectively. The risk factors studied were related to socioeconomic profile, life style, reproduction, diet and bile acids. On comparing GBC patients (mean age 51.7 years; 130 females) with healthy controls, risk factors were chemical exposure [odd ratios (OR): 7.0 (2.7-18.2); p < 0.001)], family history of gallstones [OR: 5.3 (1.5-18.9); p < 0.01)], tobacco [OR: 4.1 (1.8-9.7); p < 0.001)], fried foods [OR: 3.1 (1.7-5.6); p < 0.001], joint family [OR: 3.2 (1.7-6.2); p < 0.001], long interval between meals [OR: 1.4 (1.2-1.6); p < 0.001] and residence in Gangetic belt [OR: 3.3 (1.8-6.2); p < 0.001]. On comparing GBC cases with gallstone controls, risk factors were female gender [OR: 2.4 (1.3-4.3); p = 0.004], residence in Gangetic belt [OR: 2.3 (1.2-4.4); p = 0.012], fried foods [OR: 2.5 (1.4-4.4); p < 0.001], diabetes [OR: 2.7 (1.2-6.4); p = 0.02)], tobacco [OR 3.8 (1.7-8.1); p < 0.001)] and joint family [OR: 2.1 (1.2-3.4); p = 0.004]. The ratio of secondary to primary bile acids was significantly higher in GBC cases than gallstone controls (20.8 vs. 0.44). Fried foods, tobacco, chemical exposure, family history of gallstones, residence in Gangetic belt and secondary bile acids were significant risk factors for GBC. Copyright © 2012 UICC.

To investigate the quality of YouTube videos on gallstone disease and to assess viewer response according to quality. A YouTube search was performed on September 18, 2013, using the keywords ''gallbladder disease'', ''gallstone disease'', and ''gallstone treatment''. Three researchers assessed the source, length, number of views, number of likes, and days since upload. The upload source was categorised as physician or hospital (PH), medical website or TV channel, commercial website (CW), or civilian. A usefulness score was devised to assess video quality and to categorise the videos into ''very useful'', ''useful'', ''slightly useful'', or ''not useful''. Videos with misleading content were categorised as ''misleading''. One hundred and thirty-one videos were analysed. Seventy-four videos (56.5%) were misleading, 36 (27.5%) were slightly useful, 15 (11.5%) were useful, three (2.3%) were very useful, and three (2.3%) were not useful. The number of mean likes (1.3 ± 1.5 vs 17.2 ± 38.0, P = 0.007) and number of views (756.3 ± 701.0 vs 8910.7 ± 17094.7, P = 0.001) were both significantly lower in the very useful group compared with the misleading group. All three very useful videos were PH videos. Among the 74 misleading videos, 64 (86.5%) were uploaded by a CW. There was no correlation between usefulness and the number of views, the number of likes, or the length. The "gallstone flush" was the method advocated most frequently by misleading videos (25.7%). More than half of the YouTube videos on gallstone disease are misleading. Credible videos uploaded by medical professionals and filtering by the staff of YouTube appear to be necessary.

Niemann-Pick C2 (NPC2) is a lysosomal protein involved in the egress of low-density lipoprotein-derived cholesterol from lysosomes to other intracellular compartments. NPC2 has been detected in several tissues and is also secreted from the liver into bile. We have previously shown that NPC2-deficient mice fed a lithogenic diet showed reduced biliary cholesterol secretion as well as cholesterol crystal and gallstone formation. This study aimed to investigate the consequences of NPC2 hepatic overexpression on liver cholesterol metabolism, biliary lipid secretion, gallstone formation and the effect of NPC2 on cholesterol crystallization in model bile. We generated NPC2 transgenic mice (Npc2.Tg) and fed them either chow or lithogenic diets. We studied liver cholesterol metabolism, biliary lipid secretion, bile acid composition and gallstone formation. We performed cholesterol crystallization studies in model bile using a recombinant NPC2 protein. No differences were observed in biliary cholesterol content or secretion between wild-type and Npc2.Tg mice fed the chow or lithogenic diets. Interestingly, Npc2.Tg mice showed an increased susceptibility to the lithogenic diet, developing more cholesterol gallstones at early times, but did not show differences in the bile acid hydrophobicity and gallbladder cholesterol saturation indices compared to wild-type mice. Finally, recombinant NPC2 decreased nucleation time in model bile. These results suggest that NPC2 promotes cholesterol gallstone formation by decreasing the cholesterol nucleation time, indicating a pro-nucleating function of NPC2 in bile.

Gallstone-related illnesses are one of the most common reasons for emergency hospital admissions, often with serious complications. Standard treatment of uncomplicated gallstone-disease is by laparoscopic cholecystectomy, which can be safely and cost-effectively performed during a short hospital stay or as day-case. This paper aims to evaluate the referral pattern of patients with gallstones, which treatment is given and whether patients admitted as emergency could have benefited from earlier elective referral. The management of these patients is examined in the context of payment by results to determine cost and potential savings. The approach takens was prospective clinical audit and patient questionnaire in a district general hospital. Cost comparisons were made using secondary care income (NHS tariff) and estimated cost of hospitalisation, investigations and treatment. Between May and July 2007, 114 patients were admitted with symptomatic gallstones, 62 (54.4 per cent) were emergencies. Cholecystectomy was performed in all 52 elective patients and performed or planned for 59/62 (95.2 per cent) emergencies. A total 17/62 emergencies (27.4 per cent) presented with complications of gallstones. 38/62 (61.3 per cent) had similar symptoms before, with 21/38 (55.3 per cent) diagnosed in primary care or by another hospital department. 11 (52.4 per cent) of these had not been referred for a surgical opinion; taking account of age, co-morbidity and data acquired for elective admissions, the cost of their treatment could have been reduced by at least pounds 16,194. A large proportion of patients admitted with symptomatic biliary disease could have been referred earlier and electively. Such referral practice could improve the quality of care and reduce cost for the NHS both in primary and secondary care.

Spice bioactive compounds, capsaicin and curcumin, were both individually and in combination examined for antilithogenic potential during experimental induction of cholesterol gallstones in mice. Cholesterol gallstones were induced by feeding mice a high-cholesterol (0.5%) diet for 10 weeks. Groups of mice were maintained on a lithogenic diet that was supplemented with 0.015% capsaicin/0.2% curcumin/0.015% capsaicin + 0.2% curcumin. The lithogenic diet that contained capsaicin, curcumin, or their combination reduced the incidence of cholesterol gallstones by 50%, 66%, and 56%, respectively, compared with lithogenic control. This was accompanied by reduced biliary cholesterol and a marginal increase in phospholipid in these spice-fed groups. Increased cholesterol saturation index and cholesterol : phospholipid ratio in the bile caused by the lithogenic diet was countered by the dietary spice compounds. The antilithogenic influence of spice compounds was attributable to the cholesterol-lowering effect of these dietary spices in blood and liver, as well as a moderate increase in phospholipids. Decreased activities of hepatic glutathione reductase and glutathione-S-transferase caused by the lithogenic diet were countered by the combination of capsaicin and curcumin. The increased lipid peroxidation and the decreased concentration of ascorbic acid in the liver that was caused by the lithogenic diet was countered by the dietary spice compounds, individually or in combination. Thus, while the capsaicin and curcumin combination did not have an additive influence in reducing the incidence of cholesterol gallstones in mice, their combination nevertheless was more beneficial in enhancing the activity of hepatic antioxidant enzyme ─ glutathione reductase in the lithogenic situation. The antioxidant effects of dietary spice compounds are consistent with the observed reduction in cholesterol gallstones formed under lithogenic condition.

Aims: We designed this study to get insight into the disorder of lipid metabolism during cholesterol gallstone formation and evaluate the effect of ursodeoxycholic acid on the improvement of bile lithogenicity and on expression of lipid related genes. Methods: Rabbit cholesterol gallstone models were induced by high cholesterol diet. Bile, blood and liver tissues were obtained from rabbits after 0, 1, 2, 3, 4 and 5 weeks. Bile and blood lipids were measured enzymatically. 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR), cytochrome P450, family 7, subfamily A, polypeptide 1 (CYP7A1) and sterol carrier protein 2 (SCP2) mRNA expressions were detected by using quantitative real-time RT-PCR. Cholesterol saturation index (CSI) was calculated by using Carey table to represent the bile lithogenicity. Results: Rates of gallstone formation of the 4 and 5 week treatment groups were 100 %, but that of the ursodeoxycholic acid treatment group was only 33.3 %. Expression of HMGCR and SCP2 mRNA in the 4 week group was upregulated and that of CYP7A1 mRNA decreased as compared with the 0 week group. Ursodeoxycholic acid could significantly extend nucleation time of bile and lower CSI. Ursodeoxycholic acid could reduce the expression of SCP2, but couldn't influence expression of HMGCR and CYP7A1. Conclusions: Abnormal expression of HMGCR, CYP7A1 and SCP2 might lead to high lithogenicity of bile. Ursodeoxycholic acid could improve bile lipids and lower bile lithogenicity, thereby reducing the incidence of gallstones. So it might be a good preventive drug for cholesterol gallstones.

The utility of laser-induced breakdown spectroscopy (LIBS) for categorizing different types of gallbladder stone has been demonstrated by analyzing their major and minor constituents. LIBS spectra of three types of gallstone have been recorded in the 200-900 nm spectral region. Calcium is found to be the major element in all types of gallbladder stone. The spectrophotometric method has been used to classify the stones. A calibration-free LIBS method has been used for the quantitative analysis of metal elements, and the results have been compared with those obtained from inductively coupled plasma atomic emission spectroscopy (ICP-AES) measurements. The single-shot LIBS spectramore » from different points on the cross section (in steps of 0.5 mm from one end to the other) of gallstones have also been recorded to study the variation of constituents from the center to the surface. The presence of different metal elements and their possible role in gallstone formation is discussed.« less

Bile acid diarrhoea (BAD) is a common cause of chronic diarrhoea with a population prevalence of primary BAD around 1%. Previous studies have identified associations with low levels of the ileal hormone fibroblast growth factor 19 (FGF19), obesity and hypertriglyceridaemia. The aim of this study was to identify further associations of BAD. A cohort of patients with chronic diarrhoea who underwent 75 selenohomocholic acid taurate (SeHCAT) testing for BAD was further analysed retrospectively. Additional clinical details available from the electronic patient record, including imaging, colonoscopy, chemistry and histopathology reports were used to calculate the prevalence of fatty liver disease, gallstones, colonic neoplasia and microscopic colitis, which was compared for BAD, the primary BAD subset and control patients with diarrhoea. Of 578 patients, 303 (52%) had BAD, defined as a SeHCAT 7d retention value <15%, with 179 (31%) having primary BAD. 425 had an alanine aminotransferase (ALT) recorded, 184 had liver imaging and 176 had both. Overall, SeHCAT values were negatively associated with ALT (r s =-0.19, p<0.0001). Patients with BAD had an OR of 3.1 for an ALT >31 ng/mL with imaging showing fatty liver (p<0.001); similar figures occurred in the primary BAD group. FGF19 was not significantly related to fatty liver but low levels were predictive of ALT >40 IU/L. In 176 subjects with gallbladder imaging, 27% had gallstones, 7% had a prior cholecystectomy and 34% either of these. The median SeHCAT values were lower in those with gallstones (3.8%, p<0.0001), or gallstones/cholecystectomy (7.2%, p<0.001), compared with normal gallbladder imaging (14%). Overall, BAD had an OR of 2.0 for gallstones/cholecystectomy (p<0.05). BAD was not significantly associated with colonic adenoma/carcinoma or with microscopic colitis. The diagnosis of BAD is associated with fatty liver disease and with gallstones. The reasons for these associations require further investigation into potential metabolic causes.

Gallstone disease represents an important issue in the healthcare system. The principal non-invasive non-surgical medical treatment for cholesterol gallstones is still represented by oral litholysis with bile acids. The first successful and documented dissolution of cholesterol gallstones was achieved in 1972. Since then a large number of investigators all over the world, have been dedicated in biochemical and clinical studies on ursodeoxycholic acid (UDCA), demonstrating its extreme versatility. This editorial is aimed to provide a brief review of recent developments in UDCA use, current indications for its use and, the more recent advances in understanding its effects in terms of an anti-inflammatory drug.

Topical dissolution of cholesterol gallbladder stones using methyl tert-butyl ether (MTBE) is useful in symptomatic patients judged too ill for surgery. Previous studies showed that ethyl propionate (EP), a C5 ester, dissolves cholesterol gallstones rapidly in vitro, but differs from MTBE in being eliminated so rapidly by the liver that blood levels remain undetectable. Our aim was to test EP as a topical dissolution agent for cholesterol gallbladder stones. Five high-risk patients underwent topical dissolution of gallbladder stones by EP. In three patients, the solvent was instilled via a cholecystostomy tube placed previously to treat acute cholecystitis; in two patients, a percutaneous transhepatic catheter was placed in the gallbladder electively. Gallstone dissolution was assessed by chromatography, by gravimetry, and by catheter cholecystography. Total dissolution of gallstones was obtained in four patients after 6-10 hr of lavage; in the fifth patient, partial gallstone dissolution facilitated basketing of the stones. In two patients, cholesterol dissolution was measured and averaged 30 mg/min. Side effects were limited to one episode of transient hypotension and pain at the infusion site; no patient developed somnolence or nausea. Gallstone elimination was associated with relief of symptoms. EP is an acceptable alternative to MTBE for topical dissolution of cholesterol gallbladder stones in high-risk patients. The lower volatility and rapid hepatic extraction of EP suggest that it may be preferable to MTBE in this investigational procedure.

Gallstone disease (GD) is a chronic recurrent hepatobiliary disease, the basis for which is the impaired metabolism of cholesterol, bilirubin and bile acids, which is characterized by the formation of gallstones in the hepatic bile duct, common bile duct, or gallbladder. GD is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems. GD can result in serious outcomes, such as acute gallstone pancreatitis and gallbladder cancer. The epidemiology, pathogenesis and treatment of GD are discussed in this review. The prevalence of GD varies widely by region. The prevalence of gallstone disease has increased in recent years. This is connected with a change in lifestyle: reduction of motor activity, reduction of the physical load and changes to diets. One of the important benefits of early screening for gallstone disease is that ultrasonography can detect asymptomatic cases, which results in early treatment and the prevention of serious outcomes. The pathogenesis of GD is suggested to be multifactorial and probably develops from complex interactions between many genetic and environmental factors. It suggests that corticosteroids and oral contraceptives, which contain hormones related to steroid hormones, may be regarded as a model system of cholelithiasis development in man. The achievement in the study of the physiology of bile formation and the pathogenesis of GD has allowed expanding indications for therapeutic treatment of GD. PMID:22400083

Financial penalties for readmission have been expanded beyond medical conditions to include surgical procedures. Hospitals are working to reduce readmissions; however, little is known about the reasons for surgical readmission. To characterize the reasons, timing, and factors associated with unplanned postoperative readmissions. Patients undergoing surgery at one of 346 continuously enrolled US hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) between January 1, 2012, and December 31, 2012, had clinically abstracted information examined. Readmission rates and reasons (ascertained by clinical data abstractors at each hospital) were assessed for all surgical procedures and for 6 representative operations: bariatric procedures, colectomy or proctectomy, hysterectomy, total hip or knee arthroplasty, ventral hernia repair, and lower extremity vascular bypass. Unplanned 30-day readmission and reason for readmission. The unplanned readmission rate for the 498,875 operations was 5.7%. For the individual procedures, the readmission rate ranged from 3.8% for hysterectomy to 14.9% for lower extremity vascular bypass. The most common reason for unplanned readmission was surgical site infection (SSI) overall (19.5%) and also after colectomy or proctectomy (25.8%), ventral hernia repair (26.5%), hysterectomy (28.8%), arthroplasty (18.8%), and lower extremity vascular bypass (36.4%). Obstruction or ileus was the most common reason for readmission after bariatric surgery (24.5%) and the second most common reason overall (10.3%), after colectomy or proctectomy (18.1%), ventral hernia repair (16.7%), and hysterectomy (13.4%). Only 2.3% of patients were readmitted for the same complication they had experienced during their index hospitalization. Only 3.3% of patients readmitted for SSIs had experienced an SSI during their index hospitalization. There was no time pattern for readmission, and early (≤7 days postdischarge) and late (>7 days postdischarge) readmissions were associated with the same 3 most common reasons: SSI, ileus or obstruction, and bleeding. Patient comorbidities, index surgical admission complications, non-home discharge (hazard ratio [HR], 1.40 [95% CI, 1.35-1.46]), teaching hospital status (HR, 1.14 [95% CI 1.07-1.21]), and higher surgical volume (HR, 1.15 [95% CI, 1.07-1.25]) were associated with a higher risk of hospital readmission. Readmissions after surgery were associated with new postdischarge complications related to the procedure and not exacerbation of prior index hospitalization complications, suggesting that readmissions after surgery are a measure of postdischarge complications. These data should be considered when developing quality indicators and any policies penalizing hospitals for surgical readmission.

Postoperative ileus is a poorly understood multifactorial outcome following colorectal surgery that presents significant clinical challenges and contributes to increased morbidity, length of stay, and healthcare cost. To date, there are few pharmacological interventions that shorten the duration of postoperative ileus. This study is the first to evaluate the efficacy of simethicone in treating postoperative ileus symptoms in patients undergoing colorectal surgery. A multicenter, double-blinded, placebo controlled randomized controlled trial. This trial was conducted at two academic tertiary care centres in Ontario, Canada. 118 patients undergoing colorectal surgery. Patients were randomized to receive either a five-day course of oral simethicone (n = 58) or a placebo (n = 60). The primary outcome was time to first passage of flatus. Secondary outcomes included time to first bowel movement, postoperative length of stay, and postoperative pain. Statistical analyses were performed on an intention-to-treat basis. Statistical significance set at p = 0.05. The median time to first passage of flatus in simethicone arm was 25.2 h and 26.7 h in controls (P = 0.98). There were no significant differences in the median time to first bowel movement (simethicone = 41.1 h vs. control = 42.9 h, P = 0.91) or median length of hospital stay (simethicone = 4.5 days vs. control = 4.0 days, P = 0.63). This study failed to show a difference in return of gastrointestinal motility in patients receiving simethicone following colorectal surgery. Postoperative ileus remains a significant clinical and economic burden to the healthcare system and further research is needed to identify a reliable and effective method of treatment.

Sigmoid volvulus (SV) is an exceptionally rare but potentially life-threatening condition in children. Abdominal distention for 1 week. Sigmoid volvulus. We present a case of a 12-year-old boy with mechanical ileus who was finally confirmed to have SV with the combination of abdominal plain film, sonography, and computed tomography (CT) with the finding of mesenteric artery rotation. Because bowel obstruction was suspected, abdominal plain film, sonography, and CT were performed. The abdominal CT demonstrated whirlpool sign with torsion of the sigmoid vessels. In addition, lower gastrointestinal filling study showed that the contrast medium could only reach the upper descending colon. Therefore, he received laparotomy with mesosigmoidoplasty for detorsion of the sigmoid. The postoperative recovery was smooth under empirical antibiotic treatment with cefazolin. A follow-up lower gastrointestinal series on the seventh day of admission showed no obstruction compared with the previous series. He was finally discharged in a stable condition 8 days after admission. SV is a congenital anomaly and an uncommon diagnosis in children. Nevertheless, case series and case reports of SV are becoming more prevalent in the literature. Failure to recognize SV may result in life-threatening complications such as sigmoid gangrene/perforation, peritonitis, sepsis, and death. Thus, if the children have persistent and recurrent abdominal distention, abdominal pain, and vomiting, physicians should consider SV as a "do not miss diagnosis" in the differential diagnosis.

AIM: To determine the effects of genetic variants associated with gallstone formation and capsaicin (a pungent component of chili pepper) metabolism on the risk of gallbladder cancer (GBC). METHODS: A total of 57 patients with GBC, 119 patients with gallstones, and 70 controls were enrolled in this study. DNA was extracted from their blood or paraffin block sample using standard commercial kits. The statuses of the genetic variants were assayed using Taqman® SNP Genotyping Assays or Custom Taqman® SNP Genotyping Assays. RESULTS: The non-ancestral T/T genotype of apolipoprotein B rs693 polymorphism was associated with a decreased risk of GBC (OR: 0.14, 95% CI: 0.03-0.63). The T/T genotype of cholesteryl ester transfer protein (CETP) rs708272 polymorphism was associated with an increased risk of GBC (OR: 5.04, 95% CI: 1.43-17.8). CONCLUSION: Genetic variants involved in gallstone formation such as the apolipoprotein B rs693 and CETP rs708272 polymorphisms may be related to the risk of developing GBC in Chilean women.

Obesity has been associated with worse infectious disease outcomes. It is a risk factor for cholesterol gallstones, but little is known about associations between body mass index (BMI) and biliary infections. We studied this using factors associated with biliary infections. A total of 427 patients with gallstones were studied. Gallstones, bile, and blood (as applicable) were cultured. Illness severity was classified as follows: none (no infection or inflammation), systemic inflammatory response syndrome (fever, leukocytosis), severe (abscess, cholangitis, empyema), or multi-organ dysfunction syndrome (bacteremia, hypotension, organ failure). Associations between BMI and biliary bacteria, bacteremia, gallstone type, and illness severity were examined using bivariate and multivariate analysis. BMI inversely correlated with pigment stones, biliary bacteria, bacteremia, and increased illness severity on bivariate and multivariate analysis. Obesity correlated with less severe biliary infections. BMI inversely correlated with pigment stones and biliary bacteria; multivariate analysis showed an independent correlation between lower BMI and illness severity. Most patients with severe biliary infections had a normal BMI, suggesting that obesity may be protective in biliary infections. This study examined the correlation between BMI and biliary infection severity. Published by Elsevier Inc.

This review presents the instrumental methods used for chemical and phase composition investigation of gallstones. A great body of data has been collected in the literature on the presence of elements and their concentrations, obtained by fluorescence microscopy, X-ray fluorescence spectroscopy, neutron activation analysis, proton (particle) induced X-ray emission, atomic absorption spectroscopy, high-resolution gamma-ray spectrometry, electron paramagnetic resonance. Structural methods—powder X-ray diffraction, infrared spectroscopy, Raman spectroscopy—provide information about organic and inorganic phases in gallstones. Stone morphology was studied at the macrolevel with optical microscopy. Results obtained by analytical scanning and transmission electron microscopy with X-ray energy dispersive spectrometry are discussed. The chemical composition and structure of gallstones determine the strategy of removing stone from the body and treatment of patients: surgery or dissolution in the body. Therefore one chapter of the review describes the potential of dissolution methods. Early diagnosis and appropriate treatment of the disease depend on the development of clinical methods for in vivo investigation, which gave grounds to present the main characteristics and potential of ultrasonography (ultrasound scanning), magnetic resonance imaging, and X-ray computed tomography.

A 39-year-old woman with acute cholecystitis and gallstones underwent laparoscopic cholecystectomy. She suffered from recurrent episodes of cholangitis due to injury of the major bile ducts during laparoscopic cholecystectomy. Hepatobiliary scintigraphy with Tc-99m Sn-N-pyridoxyl-5-methyltryptophan was performed. Although normal bile excretion was found from the left hepatic duct to the percutaneous transhepatic biliary drainage (PTBD) tube, excretion from the right hepatic lobe was prolonged. Scintigraphy with Tc-99m diethylenetriaminepentaacetic acid-galactosyl human serum albumin demonstrated atrophy of the right hepatic lobe and enlargement of the left hepatic lobe. Cholangiography via the PTBD tube revealed complete obstruction of the left hepatico-jejunal anastomosis and could not enhance the right intrahepatic bile duct. A right hepatic lobectomy was performed because of the atrophy, glissonitis and the absence of an appropriate bile duct for reconstruction. Postoperatively she was active and exhibited no evidence of recurrent cholangitis.

Early definitive treatment (cholecystectomy or endoscopic sphincterotomy in the same admission or within 2 weeks after discharge) of gallstone disease after a biliary attack of acute pancreatitis is standard of care. This study investigated whether compliance with early definitive treatment for acute gallstone pancreatitis can be used as a care quality indicator for the condition. A retrospective cohort study was conducted using the Hospital Episode Statistics database. All emergency admissions to National Health Service hospitals in England with a first time diagnosis of acute gallstone pancreatitis in the financial years 2008, 2009 and 2010 were examined. Trends in early definitive treatment between hospital trusts were examined and patient morbidity outcomes were determined. During the study interval there were 19 510 patients with an overall rate of early definitive treatment at 34·7 (range 9·4-84·7) per cent. In the 1-year follow-up period, 4661 patients (23·9 per cent) had one or more emergency readmissions for complications related to gallstone pancreatitis. Of these, 2692 (57·8 per cent) were readmissions for acute pancreatitis; 911 (33·8 per cent) were within the first 2 weeks of discharge, with the remaining 1781 (66·2 per cent) occurring after the point at which definitive treatment should have been received. Early definitive treatment resulted in a 39 per cent reduction in readmission risk (adjusted risk ratio (RR) 0·61, 95 per cent c.i. 0·58 to 0·65). The risk was further reduced for acute pancreatitis readmissions to 54 per cent in the early definitive treatment group (adjusted RR 0·46, 0·42 to 0·51). In acute gallstone pancreatitis, compliance with recommended early definitive treatment varied considerably, with associated variation in outcomes. Compliance should be used as a quality indicator to improve care. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

Bile formation and secretion are essential functions of the hepatobiliary system. Bile flow is generated by transepithelial transport of water and ionic/nonionic solutes via transcellular and paracellular pathways that is mainly driven by osmotic pressure. We examined the role of tight junction-based paracellular transport in bile secretion. Claudins are cell-cell adhesion molecules in tight junctions that create the paracellular barrier. The claudin family has 27 reported members, some of which have paracellular ion- and/or water-channel-like functions. Claudin 2 is a paracellular channel-forming protein that is highly expressed in hepatocytes and cholangiocytes; we examined the hepatobiliary system of claudin 2 knockout (Cldn2(-/-)) mice. We collected liver and biliary tissues from Cldn2(-/-) and Cldn2(+/+) mice and performed histologic, biochemical, and electrophysiologic analyses. We measured osmotic movement of water and/or ions in Cldn2(-/-) and Cldn2(+/+) hepatocytes and bile ducts. Mice were placed on lithogenic diets for 4 weeks and development of gallstone disease was assessed. The rate of bile flow in Cldn2(-/-) mice was half that of Cldn2(+/+) mice, resulting in significantly more concentrated bile in livers of Cldn2(-/-) mice. Consistent with these findings, osmotic gradient-driven water flow was significantly reduced in hepatocyte bile canaliculi and bile ducts isolated from Cldn2(-/-) mice, compared with Cldn2(+/+) mice. After 4 weeks on lithogenic diets, all Cldn2(-/-) mice developed macroscopically visible gallstones; the main component of the gallstones was cholesterol (>98%). In contrast, none of the Cldn2(+/+) mice placed on lithogenic diets developed gallstones. Based on studies of Cldn2(-/-) mice, claudin 2 regulates paracellular ion and water flow required for proper regulation of bile composition and flow. Dysregulation of this process increases susceptibility to cholesterol gallstone disease in mice. Copyright © 2014 AGA Institute. Published by Elsevier Inc. All rights reserved.

Recognition of Non alcoholic fatty liver disease (NAFLD) and metabolic syndrome in patients with gallstones undergoing laparoscopic or open cholecystectomy, along with it we will also study the life style of patients with gall stones. Patients with gallstones have associated NAFLD, with concurrent metabolic syndrome and these ailments share similar factors for example obesity, hypertriglyceridemia and diabetes mellitus. Factors like body mass index, gender, raised lipid levels, use of contraceptives and alcohol and having diabetes, physical inactiveness, multiparous women, water with excessive iron content, metabolic syndrome, and NAFLD are accountable factors for gallstones formation. This was a case series done at Surgical Unit 1 of Civil Hospital Karachi. Selective samples of 88 patients were included. Duration was 3 months. We included both sexes with ultrasound proof of gall stone irrespective of cholecystitis. Excluded patients with history of seropositive viral hepatitis, autoimmune and wilson's disease. As these conditions can act as a confounder to our variables. Nafld was present in 62.5%(n = 55) while 28.4% (n = 25) had metabolic syndrome. 26.94% had BMI less than 18, 32.12 had BMI between 18 and 25 and majority had BMI greater than 25 i.e in 40.93%. Of all 46.6% had a family history of cholelithiasis. Gallstone patients with NAFLD reported about their first degree relative being suffering from cholelithiasis at a significant p-value of 0.034 while this was not significant in cases of metabolic syndrome and the p -value was 0.190. We found association of metabolic syndrome with gallstones and NAFLD. Non alcoholic fatty liver was highly prevalent in our study subjects. Huge percentage of first degree relatives of gall stone patients had gallstones and this relation was more pronounced patients who had associated NAFLD.

Cystic fibrosis (CF) is a monogenic disease due to mutations in the CFTR gene. Yet, variability in CF disease presentation is presumed to be affected by modifier genes, such as those recently demonstrated for the pulmonary aspect. Here, we conduct a modifier gene study for meconium ileus (MI), an intestinal obstruction that occurs in 16–20% of CF newborns, providing linkage and association results from large family and case–control samples. Linkage analysis of modifier traits is different than linkage analysis of primary traits on which a sample was ascertained. Here, we articulate a source of confounding unique to modifier gene studies and provide an example of how one might overcome the confounding in the context of linkage studies. Our linkage analysis provided evidence of a MI locus on chromosome 12p13.3, which was segregating in up to 80% of MI families with at least one affected offspring (HLOD = 2.9). Fine mapping of the 12p13.3 region in a large case–control sample of pancreatic insufficient Canadian CF patients with and without MI pointed to the involvement of ADIPOR2 in MI (p = 0.002). This marker was substantially out of Hardy–Weinberg equilibrium in the cases only, and provided evidence of a cohort effect. The association with rs9300298 in the ADIPOR2 gene at the 12p13.3 locus was replicated in an independent sample of CF families. A protective locus, using the phenotype of no-MI, mapped to 4q13.3 (HLOD = 3.19), with substantial heterogeneity. A candidate gene in the region, SLC4A4, provided preliminary evidence of association (p = 0.002), warranting further follow-up studies. Our linkage approach was used to direct our fine-mapping studies, which uncovered two potential modifier genes worthy of follow-up. PMID:19662435

Air Swallowing Caused Recurrent Ileus in Tourette’s Syndrome

Frye, Richard E.; Hait, Elizabeth J.

2008-01-01

This report describes an adolescent boy who has Tourette’s syndrome and developed a subtle but significant increase in vocal tics after an 8-month respite. The increase in vocal tics was associated with an acute increase in psychological stressors and resulted in recurrent air swallowing, which, in turn, caused abdominal cramping, eructation, and flatus, eventually leading to aeroenteria. Air swallowing was recognized only after a second hospital admission for recurrent ileus. Air swallowing and associated symptoms were mitigated by reinstitution of psychopharmacologic treatment and an increase in the patient’s self-awareness of the air-swallowing behavior. Clinically significant air swallowing has not been described previously in Tourette syndrome or a tic disorder. This case is important for pediatricians and pediatric gastroenterologists because either may be the first to evaluate a child or an adolescent with unexplained recurrent ileus. This report also documents the importance of the connection between the brain and the body. PMID:16651280

We herein describe a case of acute emphysematous cholecystitis in which the patient presented with symptoms of ileus. The patient was a 72-year-old man with no history of diabetes mellitus. He presented with epigastric pain, vomiting, and low-grade fever. Plain abdominal radiography showed some intestinal gas and niveau, and he was admitted to our hospital with a diagnosis of ileus. The next day, the abdominal pain increased and was accompanied by muscular defense. Plain radiography and computed tomography of the abdomen were carried out, and an emergency laparotomy was performed under a diagnosis of panperitonitis due to a perforation of the gallbladder caused by acute emphysematous cholecystitis. The patient made favorable progress after the operation and was discharged on postoperative day 14. Percutaneous transhepatic gallbladder drainage has been increasingly performed for the treatment of acute emphysematous cholecystitis. but when a perforation of the gallbladder is suspected, a laparotomy first should be considered.

Postoperative ileus (POI) is a frequent occurrence after abdominal and other types of surgery, and is associated with significant morbidity and costs to health care providers. The aims of this narrative review were to provide an update of classification systems, preventive techniques, pathophysiological mechanisms, and treatment options for established POI. The Web of Science, MEDLINE, PubMed and Google Scholar databases were searched using the key phrases 'ileus', 'postoperative ileus' and 'definition', for relevant studies published in English from January 1997 to August 2014. POI is still a problematic and frequent complication of surgery. Fluid overload, exogenous opioids, neurohormonal dysfunction, and gastrointestinal stretch and inflammation are key mechanisms in the pathophysiology of POI. Evidence is supportive of thoracic epidural analgesia, avoidance of salt and water overload, alvimopan and gum chewing as measures for the prevention of POI, and should be incorporated into perioperative care protocols. Minimal access surgery and avoidance of nasogastric tubes may also help. Novel strategies are emerging, but further studies are required for the treatment of prolonged POI, where evidence is still lacking. Although POI is often inevitable, methods to reduce its duration and facilitate recovery of postoperative gastrointestinal function are evolving rapidly. Utilisation of standardised diagnostic classification systems will help improve applicability of future studies.

Meconium ileus has been detected as a risk factor for development of liver disease in cystic fibrosis, with influence on morbidity and mortality. To evaluate the effect of early treatment with ursodeoxycholic acid in patients with cystic fibrosis and meconium ileus to prevent chronic hepatic involvement and to explore the potential role of therapy on clinical outcomes. 26 cystic fibrosis patients with meconium ileus (16 M, mean age 8,4 years, range 3,5-9) were assigned to two groups: group 1 (14 patients) treated early with ursodeoxycholic acid (UDCAe); group 2 (12 patients) treated with ursodeoxycholic acid at the onset of cystic fibrosis liver disease (UDCAd). Anthropometric data, pulmonary function tests, pancreatic status, complications such as diabetes, hepatic involvement and Pseudomonas aeruginosa colonisation were compared among groups. A higher prevalence of cystic fibrosis chronic liver disease was observed in the UDCAd group with a statistically significant difference at 9 years of age (p<0.05). Chronic infection by P. aeruginosa was found in 7% of UDCAe and 33% of UDCAd (p<0.05). No differences were observed in nutritional status and other complications. Early treatment with ursodeoxycholic acid may be beneficial in patients at risk of developing cystic fibrosis chronic liver disease such as those with meconium ileus. Multicentre studies should be encouraged to confirm these data. Copyright 2009 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

Fifty seven patients were selected from 620 cases with gallstones to be treated with an electromagnetic shock wave generator (Lithostar Plus). The machine has an overhead module with an electromagnetic generator able to produce 150-150 bar of pressure in the center of the focal zone (2 x 8 cms.) An in line ultrasound probe permits in vivo view of stone localization and fragmentations. The wide aperture of the device permits to treat patients with little pain in ambulatory basis. The mean age of the patients was 50 +/- 14 years, 57 were female and 20 were male. Stones were single in 35 cases and were multiple (2-4 gallstones) in the rest. The patients received a mean of 2620 +/- 371 shock waves. Intravenous analgesia (Fentanyl 87 +/- 40 ug p/session) was required in 26 cases. In 58.5% of the cases, fragmentation produced gallstone-rests of < 0.5 cm. Larger fragments (> 0.5 cm), were observed after an initial shock wave session in 33%. These patients underwent additional treatments sessions. Hence patients received 1.8 +/- 0.8 sessions. Minor fragmentation or no fragmentation after the first session was observed in the 14.5%. Mild biliary pain appeared in 17 patients and acute biliary colic in 2, one of these underwent emergency cholecystectomy. Overall gallstone disappearance after one year after lithotripsy, plus bile acid therapy (10-12 mg Kg day) was 72%. Patients with single gallstones were free of stones of fragments in 92% of the cases, after the same period of follow up.

The incidence of gallbladder sludge or gallstone formation in bedridden patients with cerebrovascular disease (CVD) remains obscure. The aim of this study was to determine the incidence, relationship to feeding method, and mechanisms of gallbladder sludge and gallstone formation in elderly patients with CVD. Using ultrasonography, we determined the development of gallbladder sludge and gallstone over a 12-month period, the area of the gallbladder, the gallbladder contractile response to cerulein, and fasting levels of plasma cholecystokinin (CCK) in 40 bedridden elderly patients with CVD. The patients were divided into three groups based on the feeding method: oral ingestion (OI), nasogastric feeding (NF), and total parenteral nutrition (TPN). Gallbladder sludge and gallstone were not observed in any of the 14 OI patients, but occurred in 6 and 1 of the 11 NF patients, and in 14 and 3 of the 15 TPN patients, respectively. Fasting gallbladder areas were significantly larger in the TPN group than in the other two groups. The TPN group showed a marked decrease in cerulein-induced gallbladder contractility. Fasting plasma CCK levels were lower in the TPN group than in the OI group. Our results indicate that elderly patients with CVD confined to bed over long periods are not necessarily at risk of gallbladder sludge or gallstone formation, and the development of these features may be associated with the feeding method. The predisposition of CVD patients on TPN to gallbladder disease is probably caused by failure of gallbladder contraction, resulting from insufficient secretion of CCK and impaired sensitivity of the gallbladder to CCK.

The aim was to study prospectively primary endoscopic treatment of CBD stones and further the long-term need for renewed gallstone disease interventions, defined as short- and long-term outcome. Seven years prospective follow-up of 101 consecutive patients with CBD stones who underwent endoscopic treatment with the intent of primarily achieving duct clearance. Many patients underwent several endoscopy sessions before stone clearance was completed in 83%. Eleven patients were treated surgically, 2 patients received a permanent stent, and the remaining 3 became stone free with other means. Complications occurred in 47 patients. During follow-up, 31 patients were readmitted for gallstone disease and 15 of these had recurrent CBD stones. Ten percent (8/78) of patients with the gallbladder in situ had acute cholecystitis during follow-up and late cholecystectomy was carried out in 22%. Risk factors for new gallstone disease were an in situ gallbladder containing stones and previous episodes of CBD stones. A goal of complete CBD stone clearance with ERC and ES proved to be relatively resource consuming. Subsequent cholecystectomy after duct clearance for CBD should be advised when the gallbladder lodges gallstones, especially in younger patients. Recurrent CBD stones were not influenced by cholecystectomy.

The benefit of intraoperative cholangiography (IOC) is controversial in patients with gallstone pancreatitis whose bilirubin levels are normalizing. IOC with subsequent endoscopic retrograde cholangiopancreatography may lengthen duration of surgery and length of stay, whereas failure to clear the common bile duct may result in recurrent pancreatitis. We performed a 6-year retrospective cohort analysis of consecutive adult patients with mild gallstone pancreatitis undergoing same-admission cholecystectomy at 2 university-affiliated medical centers. Institution A routinely performed IOC, whereas institution B did not. The primary outcome was readmission within 30 days for recurrent pancreatitis. Of 520 patients evaluated, 246 (47%) were managed at institution A (routine IOC) and 274 (53%) were managed at institution B (restricted IOC). Patients at institution B had a shorter duration of surgery (1.0 vs 1.6 hours, P < .001), shorter length of stay (4 vs 5 days, P < .001), and fewer postoperative endoscopic retrograde cholangiopancreatographies performed (1.8% vs 21%, P < .001), without a difference in readmissions (1.5% vs 0%, P = .12). Routine IOC is not necessary in the setting of mild gallstone pancreatitis with normalizing bilirubin values. Copyright © 2016 Elsevier Inc. All rights reserved.

Previous studies have shown that recovery of colonic transit is a major determinant of post-operative ileus and clinical recovery after gastrointestinal surgery. Prucalopride is a highly selective 5-hydroxytryptamine receptor-4 agonist with colonic pro-motility effects. To evaluate the effect and safety of prucalopride on post-operative ileus and surgical outcomes after elective gastrointestinal surgery. In this phase II randomised clinical trial, 110 patients undergoing elective gastrointestinal surgery were randomised to either oral prucalopride (2 mg/day) (n = 55) or placebo (n = 55). Intervention was started 24 h after surgery and stopped after defecation or maximally at 7 days. The primary outcome was time to defecation. Secondary outcomes included time to first passage of flatus, tolerance of solid food, nasogastric tube reinsertion, post-operative length of stay, hospital readmission, overall cost, time to walk independently, surgical complications and inflammatory parameters. Patients who received prucalopride had a shorter time to defecation (65.0 vs. 94.5 h, P = 0.001), passage of flatus (53.0 vs. 73.0 h, P < 0.001), and post-operative length of stay (7.0 vs. 8.0 days, P = 0.001) than controls. The number of patients with prolonged ileus (>5 days) (16.4% vs. 34.5%, P = 0.026) and the C-reactive protein level on post-operative day 5 (35.67 vs. 59.07 mg/L, P = 0.040) were lower in the prucalopride group. There was no significant difference in post-operative Clavien-Dindo grade III and IV complications (P = 0.606) between the groups. Prucalopride is a safe and effective treatment to reduce post-operative ileus and systemic inflammation without affecting post-operative complications in patients undergoing elective gastrointestinal surgery.

Medical dissolution of gallstone is usually performed on radiolucent gallstones in a functioning gallbladder. However, absence of visible gallstone on plain abdominal x-ray does not always preclude calcification. This study aims to compare the response and dissolution rates between ursodeoxycholic acid (UDCA) alone or in combination with chenodeoxycholic acid (CDCA) according to stone density on computed tomography (CT) scan. A total of 126 patients underwent dissolution therapy with either UDCA alone or combination of CDCA and UDCA (CNU) from December 2010 to March 2014 at Korea University Ansan Hospital. In the end, 81 patients (CNU group = 44, UDCA group = 37) completed dissolution therapy for 6 months. Dissolution rate (percentage reduction in the gallstone volume) and response to therapy (complete dissolution or partial dissolution defined as reduction in stone volume of >50%) were compared between the 2 groups. Dissolution and response rates of sludge was also compared between the 2 groups. The overall response rate was 50.6% (CNU group 43.2% vs UDCA group 59.5%, P = 0.14), and the overall dissolution rate was 48.34% (CNU group 41.5% vs UDCA group 56.5%, P = 0.13). When analyzed according to stone density, response rate was 33.3%, 87.1%, 30.0%, and 6.2% for hypodense, isodense, hyperdense, and calcified stones, respectively. Response rate (85.7% vs 88.2%, P = 0.83) and dissolution rate (81.01% vs 85.38%, P = 0.17) of isodense stones were similar between CNU and UDCA group. When only sludge was considered, the overall response rate was 87.5% (CNU group 71.4% vs UDCA group 94.1%, P = 0.19), and the overall dissolution rate was 85.42% (CNU group 67.9% vs UDCA group 92.7%, P = 0.23). Patients with isodense gallstones and sludge showed much better response to dissolution therapy with CNU and UDCA showing comparable efficacy. Therefore, CT scan should be performed before medication therapy if stone dissolution is intended.

Gallstone disease is a common gastrointestinal disorder in industrialised countries. Although symptoms can be severe, some people can be symptom free for many years after the original attack. Surgery is the current treatment of choice, but evidence suggests that observation is also feasible and safe. We reviewed the evidence on cholecystectomy versus observation for uncomplicated symptomatic gallstones and conducted a cost-effectiveness analysis. We searched six electronic databases (last search April 2014). We included randomised controlled trials (RCTs) or non-randomised comparative studies where adults received either cholecystectomy or observation/conservative management for the first episode of symptomatic gallstone disease (biliary pain or cholecystitis) being considered for surgery in secondary care. Meta-analysis was used to combine results. A de novo Markov model was developed to assess the cost effectiveness of the interventions. Two RCTs (201 participants) were included. Eighty-eight percent of people randomised to surgery and 45 % of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications (RR = 6.69, 95 % CI = 1.57-28.51, p = 0.01), in particular acute cholecystitis (RR = 9.55, 95 % CI = 1.25-73.27, p = 0.03), and less likely to undergo surgery (RR = 0.50, 95 % CI = 0.34-0.73, p = 0.0004) or experience surgery-related complications (RR = 0.36, 95 % CI = 0.16-0.81, p = 0.01) than those randomised to surgery. Fifty-five percent of people randomised to observation did not require surgery, and 12 % of people randomised to cholecystectomy did not undergo surgery. On average, surgery costs £1,236 more per patient than conservative management, but was more effective. Cholecystectomy is the preferred treatment for symptomatic gallstones. However, approximately half the observation group did not require surgery or suffer complications indicating that it may be a valid alternative to surgery. A multicentre trial is needed to establish the effects, safety and cost effectiveness of observation/conservative management relative to cholecystectomy.

Prolonged ileus as a sole manifestation of pseudomembranous enterocolitis.

Pseudomembranous colitis usually manifests as fever and diarrhea in hospitalized patients treated with systemic antibiotics. We present a case that represents a unique variant. The 44-year-old man suffered of several weeks of abdominal pain, low-grade fever, nausea, vomiting, and lack of bowel movements. Upper gastrointestinal barium swallow and passage series revealed evidence of severe intestinal hypomotility. A thorough evaluation for the cause of the patient's ileus and abdominal pain was unrevealing, and symptomatic treatment was ineffective. Following the administration of opiates and dietary fiber supplementation the patient's abdominal pain and distention rapidly worsened, requiring an urgent subtotal colectomy. The macroscopic and microscopic appearance of the excised colon as well as results of the colonic cytotoxin essay and fecal enzyme-linked immunosorbent assay essay confirmed the diagnosis of severe Clostridium difficile induced pseudomembranous colitis as the cause of the patient's illness. To our knowledge, this is the first reported case of Clostridium-difficile induced disease consisting of prolonged ileus in the absence of diarrhea in a patient not previously taking antibiotics.

Although Helicobacter pylori DNA sequences have been detected in cholecystic bile and tissue of patients with gallstones, controversial results are reported from different geographic areas. To detect H. pylori in cholecystic bile and tissue of patients with gallstones from a previously uninvestigated geographic area, southern Italy. Detection included both the bacterial DNA and the specific antigen (H. pylori stool antigen) identified in the stools of infected patients for diagnostic purposes. The study enclosed 33 consecutive patients undergoing laparoscopic cholecystectomy for gallstones. DNA sequences of H. pylori were detected by polymerase chain reaction in both cholecystic bile and tissue homogenate. Moreover, we assayed H.pylori stool antigen on gall-bladder cytosolic and biliary proteins after their extraction. Bacterial presence in the stomach was assessed by urea breath test in all patients and Deltadelta13CPDB value assumed as marker of intragastric load. Fisher's exact probability and Student's t-tests were used for statistical analysis. DNA sequences of H. pylori in bile were found in 51.5% and significantly correlated with its presence in cholecystic tissue homogenate (P<0.005), H. pylori stool antigen in gall-bladder (P=0.0013) and bile (P=0.04) proteins, gastric infection (P<0.01) and intragastric bacterial load (P<0.001). No correlation was found, however, with sex and age of the patients. Our prevalence value of bacterial DNA in bile and gall-bladder of patients with gallstones agreed with that of the only other Italian study. The simultaneous presence of both bacterial DNA and proteic antigen suggests that the same prototype of bacterium could be located at both intestinal and cholecystic level and, therefore, the intestine represents the source of biliary contagion.

AIM: An increased viscosity of gallbladder bile has been considered an important factor in the pathogenesis of gallstone disease. Besides lipids and proteins, mucin has been suggested to affect the viscosity of bile. To further clarify these issues we compared mucin, protein and the lipid componEnts of hepatic and gallbladder bile and its viscosity in patients with gallstones. METHODS: Viscosity of bile (mPa.s) was measured using rotation viscosimetry in regard to the non Newtonian property of bile at low shear rates. RESULTS: Biliary viscosity was markedly higher in gallbladder bile of patients with cholesterol (5.00 ± 0.60 mPa.s, mean ± SEM, n = 28) and mixed stones (3.50 ± 0.68 mPa.s; n = 8) compared to hepatic bile (0.92 ± 0.06 mPa.s, n = 6). A positive correlation between mucin and viscosity was found in gallbladder biles (r = 0. 65; P < 0.001) but not in hepatic biles. The addition of physiologic and supraphysiologic amounts of mucin to gallbladder bile resulted in a dose dependent non linear increase of its viscosity. A positive correlation was determined between phospholipid concentration and viscosity (r = 0.34, P < 0.005) in gallbladder biles. However, no correlation was found between total protein or the other lipid concentrations and viscosity in both gallbladder and hepatic biles. CONCLUSION: The viscosity of gallbladder bile is markedly higher than that of hepatic bile in patients with gallstones. The concentration of mucin is the major determinant of biliary viscosity and may contribute by this mechanism to the role of mucin in the pathogenesis of gallstones. PMID:11819761

Gallstone disease (GD) is highly correlated with metabolic syndrome and its related illnesses including type II diabetes (DMII) and polycystic ovary syndrome (PCOS). While previous studies claimed that metformin decreases the chance of developing GD in PCOS patients, this phenomenon has not been investigated in animal models to date. Here we fed a high fat diet (HFD) containing 2% of cholesterol and 1% of cholic acid to ten-week-old male C57Bl/6 mice for 105 days. The groups were as follows: Low fat diet; HFD; HFD + Ursodeoxycholic acid (UDCA) (day 1-105); HFD + Metformin (day 1-105); HFD + Metformin (Met) (day 64-105). All drugs were administered by oral gavage (Met = 300 mg/kg & UDCA = 750 mg/kg). Serum lipid profile and gross organ examination were performed after euthanasia. A microscopic evaluation of the paraffin-embedded gallbladders was done after hematoxylin & eosin and Von Kossa staining. HFD successfully induces gallstone (4 out of 4 of the HFD members). While both UDCA and metformin (d 1-105) prevented gallstone formation and cholecystitis, Metformin (d 64-105) group had a few small stones. Additionally, metformin induces mucosal calcification in gallbladder (porcelain GB) of more than 80% of the HFD + Met (day 1-105) and HFD + Met (day 64-105) groups, collectively, which can be a potential problem by itself. While metformin shows a noticeable benefit towards GB health by reducing the chance for gallstone formation, if it induces porcelain gallbladder in humans as well, it might inflict patients with preventable medical charges.

To determine whether virtual monochromatic imaging (VMI) increases detectability of noncalcified gallstones on dual-energy CT (DECT) compared with conventional CT imaging. This retrospective IRB-approved, HIPAA-compliant study included consecutive patients who underwent DECT of the abdomen in the Emergency Department during a 30-month period (July 1, 2013-December 31, 2015), with a comparison US or MR within 1-year. 51 patients (36F, 15M; mean age 52 years) fulfilled the inclusion criteria. All DECT were acquired on a dual-source 128 × 2 slice scanner using either 80/Sn140 or 100/Sn140 kVp pairs. Source images at high and low kVp were used for DE post-processing with VMI. Within 3 mm reconstructed images, regions of interest of 0.5 cm 2 were placed on noncalcified gallstones and bile to record hounsfield units (HU) at VMI energy levels ranging between 40 and 190 keV. Noncalcified gallstones uniformly demonstrated lowest HU at 40 keV and increase at higher keV; the HU of bile varied at higher keV. Few of the noncalcified stones are visible at 70 keV (simulating a conventional 120 kVp scan), with measured contrast (bile-stone HU difference) <10 HU in 78%, 10-20 HU in 20%, and >20 HU in 2%. Contrast was maximal at 40 keV, where 100% demonstrated >20 HU difference from surrounding bile, 75% >44 HU difference, and 50% >60 HU difference. A paired t test demonstrated a significant difference (p < 0.0001) between this stone-bile contrast at 40 vs. 70 keV and 70 vs. 190 keV. Low keV virtual monochromatic imaging increased conspicuity of noncalcified gallstones, improving their detectability.

Only one previous study has examined the association between coffee consumption and risk of acute pancreatitis, and it found a reduced risk for alcohol-related episodes among high consumers of coffee. Therefore, we examined (1) the association between coffee consumption and risk of non-gallstone-related acute pancreatitis and (2) whether this association was modified by alcohol intake. Data were obtained from two prospective cohorts, the Cohort of Swedish Men and the Swedish Mammography Cohort, including 76 731 men and women (born 1914-1952). Coffee consumption was assessed at baseline with a FFQ, and the cohorts were followed up between 1998 and 2012 via linkage to national health registries. Hazard ratios were estimated using Cox models, with adjustment for potential confounding factors. During 1 035 881 person-years of total follow-up, 383 cases (246 in men and 137 in women) of incident non-gallstone-related acute pancreatitis were identified. Overall, and irrespective of whether a categorical or a continuous exposure model was used, we observed no association between coffee consumption and risk of non-gallstone-related acute pancreatitis (e.g. the multivariable-adjusted hazard ratio for each 1 cup/d increase in coffee consumption was 0·97; 95 % CI 0·92, 1·03). There was no evidence of effect modification by alcohol intake (P interaction=0·77). In conclusion, coffee consumption was not associated with risk of non-gallstone-related acute pancreatitis in this large prospective cohort study. Because of the limited number of epidemiological studies and their conflicting results, further research is needed to elucidate this potential association.

Causal association of gallbladder stones with gallbladder cancer (GBC) is not yet well established. To study the frequency of occurrence of preneoplastic histological lesions and loss of heterozygosity (LOH) of tumor suppressor genes in patients with gallstones. All consecutive patients with gallstones undergoing cholecystectomy from 2007-2011 were included prospectively. Histological examination of the gallbladder specimens was done for preneoplastic lesions. LOH at 8 loci, that is 3p12, 3p14.2, 5q21, 9p21, 9q, 13q, 17p13, and 18q for tumor suppressor genes (DUTT1, FHIT, APC, p16, FCMD, RB1, p53, and DCC genes) that are associated with GBC was tested from microdissected preneoplastic lesions using microsatellite markers. These LOH were also tested in 30 GBC specimens. Of the 350 gallbladder specimens from gallstone patients, hyperplasia was found in 32%, metaplasia in 47.8%, dysplasia in 15.7%, and carcinoma in situ in 0.6%. Hyperplasia, metaplasia, and dysplasia alone were found in 11.7%, 24.6%, and 1.4% of patients, respectively. A combination of hyperplasia and dysplasia, metaplasia and dysplasia, and hyperplasia, metaplasia, and dysplasia was found in 3.4%, 6.3%, and 4.3% of patients, respectively. LOH was present in 2.1% to 47.8% of all the preneoplastic lesions at different loci. Fractional allelic loss was significantly higher in those with dysplasia compared with other preneoplastic lesions (0.31 vs 0.22; P = 0.042). No preneoplastic lesion or LOH was found in normal gallbladders. Patients with gallstones had a high frequency of preneoplastic lesions and accumulation of LOH at various tumor suppressor genes, suggesting a possible causal association of gallstones with GBC.

Cholecystectomy is necessary for the treatment of symptomatic or complicated gallbladder (GB) stones, but oral litholysis with bile acids is an attractive alternative therapeutic option for asymptomatic or mildly symptomatic patients. This study was conducted to evaluate the efficacy of magnesium trihydrate of ursodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA) on gallstone dissolution and to investigate improvements in gallstone-related symptoms. A prospective, multicenter, phase 4 clinical study to determine the efficacy of orally administered magnesium trihydrate of UDCA and CDCA was performed from January 2011 to June 2013. The inclusion criteria were GB stone diameter ≤15 mm, GB ejection fraction ≥50%, radiolucency on plain X-ray, and asymptomatic/mildly symptomatic patients. The patients were prescribed one capsule of magnesium trihydrate of UDCA and CDCA at breakfast and two capsules at bedtime for 6 months. The dissolution rate, response rate, and change in symptom score were evaluated. A total of 237 subjects were enrolled, and 195 subjects completed the treatment. The dissolution rate was 45.1% and the response rate was 47.2% (92/195) after 6 months of administration of magnesium trihydrate of UDCA and CDCA. Only the stone diameter was significantly associated with the response rate. Both the symptom score and the number of patients with symptoms significantly decreased regardless of stone dissolution. Adverse events necessitating discontinuation of the drug, surgery, or endoscopic management occurred in 2.5% (6/237) of patients. Magnesium trihydrate of UDCA and CDCA is a well-tolerated bile acid that showed similar efficacy for gallstone dissolution and improvement of gallstone-related symptoms as that shown in previous studies.

BACKGROUND Tracheomalacia (TM) occurs in approximately 1 in 2,100 children. Because the trachea develops abnormally in animal models of cystic fibrosis (CF), we hypothesized this may also occur in children with CF, increasing their risk of TM. PURPOSE To examine the prevalence and clinical consequences of TM in children with CF. METHODS We studied children with CF born between 1995 and 2012. TM was defined as dynamic collapse of the trachea, and the severity was recorded as described in the chart. The effect of TM on patient outcomes, including FEV1, CT changes, and acquisition of CF pathogens, was assessed using a longitudinal patient dataset. RESULTS 89% of children with CF had at least one bronchoscopy (n = 97/109). 15% of these children had TM described in any bronchoscopy report (n= 15/97). Of the patients with TM, 8 had meconium ileus (p = 0.003) and all were pancreatic insufficient. Pseudomonas aeruginosa infection occurred 1.3 years earlier among children with TM (p = 0.01). Starting FEV1 values by age 8 were diminished by over 18% of predicted for patients with TM. Life-threatening episodes of airway obstruction occurred in 3 of 15 patients with CF and TM, including one leading to death. Gender, prematurity, and hepatic disease were not associated with TM. No difference was observed in the frequency of bronchiectasis. CONCLUSIONS TM is significantly more common in infants and children with CF than in the general population and is associated with airway obstruction and earlier Pseudomonas acquisition.

A mature female squirrel monkey was noted during routine semiannual examinations to have moderate progressive weight loss. Serum chemistry panels revealed marked increases in hepatic enzyme, bilirubin, and bile salt concentrations and hypoalbuminemia. Abdominal ultrasonography revealed echogenic, shadowing debris in the gallbladder, consistent with cholelithiasis. At necropsy, marked thickening and distension of the gallbladder, cystic duct, and common bile duct was noted, and more than 50 irregularly shaped, black gallstones were removed from the biliary tract. Gallbladder tissue, bile, and gallstones cultured positive for Escherichia coli and Proteus spp., suggesting a brown-pigment gallstone type secondary to a bacterial nidus. Histopathology revealed severe chronic–active diffuse cholecystitis and severe chronic-active hepatic degeneration and necrosis with severe cholestasis. To our knowledge, this report is the first description of spontaneous choleilthiasis in a squirrel monkey. PMID:26884412

The results of an experimental study of the laser radiation effect on the crystal`s formation in the volume of biological fluids that are complex multi-component solutions have been discussing. Are investigated white and natural bile in vitro. The qualitative changes were observed. Thus, at the bottom of the cell in which bile is not exposed to the laser radiation, the crystals are formed. In the irradiated bile gallstone has a thin layer of a homogeneous viscous colloidal liquid with very small, visible in polarized light crystalline formations was got. Irradiated laser bile's gallstone was covered evenly white deposit without surface defect unlike gallstone in bile without radiation exposure. A possible mechanism to explain the laser radiation action on the mineral formation in biological fluids and also practical application of this effect have been suggesting too.

Measurement of total CO2 concentrations in bile from patients undergoing cholecystectomy because of gallstones has shown that the presence of calcium carbonate in the stones can be associated with a raised total CO2 concentration in the common duct bile. In bile from functioning and poorly-functioning gallbladders, total CO2 was nearly always related to pH irrespective of stone composition. PMID:631643

Sedentary lifestyle of human beings has resulted in various diseases and in turn we require a potential tool that can be used to address various issues related to human health. Laser Induced Breakdown Spectroscopy (LIBS) is one such potential optical analytical tool that has become quite popular because of its distinctive features that include applicability to any type/phase of samples with almost no sample preparation. Several reports are available that discusses the capabilities of LIBS, suitable for various applications in different branches of science which cannot be addressed by traditional analytical methods but only few reports are available for the medical applications of LIBS. In the present work, LIBS has been implemented to understand the role of various elements in the formation of gallstones (formed under the empyema and mucocele state of gallbladder) samples along with patient history that were collected from Purvancal region of Uttar Pradesh, India. The occurrence statistics of gallstones under the present study reveal higher occurrence of gallstones in female patients. The gallstone occurrence was found more prevalent for those male patients who were having the habit of either tobacco chewing, smoking or drinking alcohols. This work further reports in-situ LIBS study of deciduous tooth and in-vivo LIBS study of human nail.

The aim of the present study was to elucidate the mechanisms of development of cholesterol crystals and gallstones during weight reduction in obese subjects. Twenty-five morbidly obese, gallstone-free subjects underwent vertical-banded gastroplasty. Gallbladder bile was collected at the time of the operation via needle aspiration and 1.1-7.3 months after the operation via ultrasound-guided transhepatic puncture of the gallbladder. The mean weight loss was 17 kg. Two patients developed gallstones and 10 patients displayed cholesterol crystals in their bile. In patients with a follow-up time of less than 2 months (n = 13), cholesterol saturation increased from 90% to 114% but tended to decrease in the patients with a follow-up time of more than 2 months. The extraction of the concanavalin-A-binding fraction from gallbladder bile obtained after weight reduction in 7 patients prolonged crystallization detection time from 6 to 10 days. The hexosamine concentration, a marker for mucin, was increased by about 100% in bile obtained in 6 of 7 patients after weight reduction. In conclusion, the results indicate that crystallization-promoting compounds (mucin) are of great importance in the development of cholesterol crystals and gallstones in obese subjects during weight reduction, probably because of defective gallbladder emptying.

Megalin and cubilin expression in gallbladder epithelium and regulation by bile acids.

Cholesterol crystal formation in the gallbladder is a key step in gallstone pathogenesis. Gallbladder epithelial cells might prevent luminal gallstone formation through a poorly understood cholesterol absorption process. Genetic studies in mice have highlighted potential gallstone susceptibility alleles, Lith genes, which include the gene for megalin. Megalin, in conjunction with the large peripheral membrane protein cubilin, mediates the endocytosis of numerous ligands, including HDL/apolipoprotein A-I (apoA-I). Although the bile contains apoA-I and several cholesterol-binding megalin ligands, the expression of megalin and cubilin in the gallbladder has not been investigated. Here, we show that both proteins are expressed by human and mouse gallbladder epithelia. In vitro studies using a megalin-expressing cell line showed that lithocholic acid strongly inhibits and cholic and chenodeoxycholic acids increase megalin expression. The effects of bile acids (BAs) were also demonstrated in vivo, analyzing gallbladder levels of megalin and cubilin from mice fed with different BAs. The BA effects could be mediated by the farnesoid X receptor, expressed in the gallbladder. Megalin protein was also strongly increased after feeding a lithogenic diet. These results indicate a physiological role for megalin and cubilin in the gallbladder and provide support for a role for megalin in gallstone pathogenesis.

Predicting the presence of a persistent common bile duct (CBD) stone is a difficult and expensive task. The aim of this study is to determine if a previously described protocol-based scoring system is a cost-effective strategy. The protocol includes all patients with gallstone pancreatitis and stratifies them based on laboratory values and imaging to high, medium, and low likelihood of persistent stones. The patient's stratification then dictates the next course of management. A decision analytic model was developed to compare the costs for patients who followed the protocol versus those that did not. Clinical data model inputs were obtained from a prospective study conducted at The Mount Sinai Medical Center to validate the protocol from Oct 2009 to May 2013. The study included all patients presenting with gallstone pancreatitis regardless of disease severity. Seventy-three patients followed the proposed protocol and 32 did not. The protocol group cost an average of $14,962/patient and the non-protocol group cost $17,138/patient for procedural costs. Mean length of stay for protocol and non-protocol patients was 5.6 and 7.7 days, respectively. The proposed protocol is a cost-effective way to determine the course for patients with gallstone pancreatitis, reducing total procedural costs over 12 %.

Biliary cholesterol is transported by vesicles and micelles. Cholesterol microcrystals are derived from thermodynamically unstable vesicles. In experimental animals vitamin C deficiency leads to a super-saturation of biliary cholesterol and to the formation of gallstones. To search for a possible relationship between serum levels of vitamin C and the formation of cholesterol gallstones in patients with cholelithiasis. Thirteen patients with cholelithiasis and a programmed surgical intervention were treated with 2 g/day of vitamin C per os for two weeks before surgery. Forty nine patients subjected to a cholecystectomy not supplemented with vitamin C were studied as controls. Plasma concentrations of vitamin C and lipid profiles were measured. The cholesterol saturation index, crystallization time, cholesterol and phospholipid content in vesicles and micelles, separated by gel filtration chromatography, were studied in bile samples obtained from the gallbladder. Vitamin C supplementation did not change significantly plasma lipids and bile lipid concentrations. However, in supplemented patients, significant reductions in vesicular cholesterol content (6.5 ± 4.8% compared to 17.9 ± 14.0% in the control group; p < 0.05) and vesicular cholesterol/phospholipid ratio (0.71 ± 0.53 compared to 1.36 ± 1.15 in controls; p < 0.05), were observed. Vitamin C administration may modify bile cholesterol crystallization process, the first step in cholesterol gallstone formation.

Complicated bile duct stones

Roy, Ashwin; Martin, Derrick

Common bile duct stones (CBDSs) are solid deposits that can either form within the gallbladder or migrate to the common bile duct (CBD), or form de novo in the biliary tree. In the USA around 15% of the population have gallstones and of these, 3% present with symptoms annually. Because of this, there have been major advancements in the management of gallstones and related conditions. Management is based on the patient's risk profile; young and healthy patients are likely to be recommended for surgery and elderly patients with comorbidities are usually recommended for endoscopic procedures. Imaging of gallstones has advanced in the last 30 years with endoscopic retrograde cholangiopancreatography evolving from a diagnostic to a therapeutic procedure in removing CBDSs. We present a complicated case of a patient with a CBDS and periampullary diverticulum and discuss the techniques used to diagnose and remove the stone from the biliary system. PMID:23946532

To obtain pilot data to evaluate the discriminatory power of biomarkers microRNA-122 (miR-122), high-mobility group box 1 (HMGB1), full-length keratin-18 (flk-18) and caspase-cleaved keratin-18 (cck-18) in plasma to identify potential biliary complications that may require acute intervention. An observational biomarker cohort pilot study. In a Scottish University teaching hospital for 12 months beginning on 3 September 2014. Blood samples were collected from adults (≥16 years old) referred with acute biliary-type symptoms who have presented to hospital within 24 hours prior were recruited. Patients unable or refused to give informed consent or were transferred from a hospital outside the National Health Service regional trust were excluded. To evaluate whether circulating miR-122, HMGB1, flk-18 and cck-18 can discriminate between people with and without gallstone disease and uncomplicated from complicated gallstone disease during the first 24 hours of hospital admission. 300 patients were screened of which 285 patients were included. Plasma miR-122, cck-18 and flk-18 concentrations were increased in patients with gallstones compared with those without (miR-122: median: 2.89×10 4  copies/mL vs 0.90×10 4  copies/mL (p<0.001); cck-18: 121.2 U/L vs 103.5 U/L (p=0.031); flk-18: 252.4 U/L vs 145.1 U/L (p<0.001)). Uncomplicated gallstone disease was associated with higher miR-122 and cck-18 concentrations than complicated disease (miR-122: 5.72×10 4  copies/mL vs 2.26×10 4  copies/mL (p=0.023); cck-18: 139.7 U/L vs 113.6 U/L (p=0.047)). There was no significant difference in HMGB1 concentration between patients with and without gallstones (p=0.559). Separation between groups for all biomarkers was modest. miR-122 and keratin-18 plasma concentrations are elevated in patients with gallstones. However, this result is confounded by the association between biomarker concentrations, age and gender. In this pilot study, miR-122 and keratin-18 were not sufficiently discriminatory to be progressed as clinically useful biomarkers in this context. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

BACKGROUND AND PURPOSE Electrical stimulation of the vagus nerve reduces intestinal inflammation following mechanical handling, thereby shortening post-operative ileus in mice. Previous studies in a sepsis model showed that this cholinergic anti-inflammatory pathway can be activated pharmacologically by central administration of semapimod, an inhibitor of p38 mitogen-activated protein kinase. We therefore evaluated the effect of intracerebroventricular (i.c.v.) semapimod on intestinal inflammation and post-operative ileus in mice. EXPERIMENTAL APPROACH Mice underwent a laparotomy or intestinal manipulation 1 h after i.c.v. pre-treatment with semapimod (1 µg·kg−1) or saline. Drugs were administered through a cannula placed in the left lateral ventricle 1 week prior to experimentation. Twenty-four hours after surgery, gastric emptying was measured using scintigraphy, and the degree of intestinal inflammation was assessed. Finally, activation of brain regions was assessed using quantitative immunohistochemistry for c-fos. KEY RESULTS Intestinal manipulation induced inflammation of the manipulated intestine and significantly delayed gastric emptying, 24 h after surgery in saline-treated animals. Semapimod significantly reduced this inflammation and improved gastric emptying. Vagotomy enhanced the inflammatory response induced by intestinal manipulation and abolished the anti-inflammatory effect of semapimod. Semapimod but not saline induced a significant increase in c-fos expression in the paraventricular nucleus, the nucleus of the solitary tract and the dorsal motor nucleus of the vagus nerve. CONCLUSIONS AND IMPLICATIONS Our findings show that i.c.v. semapimod reduces manipulation-induced intestinal inflammation and prevented post-operative ileus. This anti-inflammatory effect depends on central activation of the vagus nerve. PMID:21371006

Small intestinal function returns first after surgery, and then the function of the stomach returns to normal after postoperative ileus (POI). The aim of this study was to investigate inflammatory responses in the muscle coat of stomach and small intestine in guinea pig POI model. The distance of charcoal migration from pylorus to the distal intestine was measured. Hematoxylin and eosin (H&E) and immunohistochemical stain for calprotectin were done from the histologic sections of stomach, jejunum and ileum obtained at 3 and 6 hour after operation. Data were compared between sham operation and POI groups. The distance of charcoal migration was significantly reduced in the 3 and 6 hour POI groups compared with sham operated groups (p<0.05). On H&E staining, the degree of inflammation was significantly higher in the stomach of 3 hour POI groups compared with jejunum and ileum of POI groups or sham operated groups (p<0.05). Calprotectin positive cells were significantly increased in the muscle coat of stomach of 3 hour POI groups compared with jejunum and ileum of POI groups or sham operated groups (p<0.05). There was strong association between the degree of inflammation and calprotectin positive cells in stomach. Postoperative ileus induced by cecal manipulation significantly increased the degree of inflammation and calprotectin positive cells in the muscle coat of stomach as a remote organ. The relevance of degree of inflammation and the recovery time of ileus should be pursued in the future research.

Optimal nutrition is essential to the recovery of burned patients. The authors evaluated the efficacy of an aggressive nutrition delivery protocol. The following protocol was implemented: initiation of tube feeds within 4 hours, acceleration to goal rate within 8 hours, and tolerance of gastric residual volumes of 400 ml. Patients on the protocol formed the study group whereas patients admitted immediately before implementation served as controls for a study period of 7 days after admission. Outcome variables included ileus, prokinetic medication use, intensive care unit and overall length of stay, ventilator days and mortality. Variables were compared using bivariate analysis. The 42 study subjects and 34 controls were similar at baseline. Time to initiation was similar (6.8 vs 9.4 hours; P = .226), however, goal rate was achieved much sooner in the study group (11.2 vs 20.9 hours; P < .001). Number of hours spent at goal was different on days 1 and 2 (6.62 vs 2.74, P = .003 and 17.24 vs 13.18, P = .032) with no difference thereafter. Residual volumes in the study group were higher from day 2 onward, and remained increased throughout the study period (401 vs 234 ml average; P = .449). Clinical ileus was much more common in the study group (8 cases vs 1, P = .037). There was no difference in length of stay or mortality. The protocol was successfully implemented and resulted in early achievement of goal tube feed rates. However, this resulted in tube feed intolerance as manifested by more cases of clinical ileus.

Assessment of gallstone predictor: comparative analysis of ultrasonographic and biochemical parameters

PubMed Central

2013-01-01

Background Gallstones represent a significant burden for health care systems worldwide and are one of the most common disorders presenting to emergency room. Ultrasonography, complete blood picture test and liver function tests are procedures of choice in suspected gallstones or biliary diseases. They are the most sensitive, specific, non-invasive and inexpensive tests for the detection of gallstones. Our main objective was to evaluate the relationship of ultrasonographic findings, hemolytic indices and liver function tests with gallstones. Methodology It was a prospective study carried out in Civil Hospital Karachi (DUHS) and Liaquat National Hospital, two largest tertiary care hospitals of Karachi, Pakistan. Duration of the study was from July 2011 to October 2012. The study was carried out on diagnosed, pre-operative and symptomatic patients of cholelithiases. Exclusion criteria were patients of gallbladder and pancreatic carcinoma, emergency operations, patients having age <12 years and non-cooperative patients, who refused to give written consent for participation in the study. Total two tests were performed on each patient after diagnosis by ultrasonography. These were complete blood count and liver function tests. All the demographic data, laboratory findings and ultrasonographic features were noted in a pre-structured Performa. Sample size was calculated by using open-epidemiological sample size calculator prevalence (p) = 35%, d = 5%, and confidence interval (CI) 95% = 350. All the data was entered and analyzed through SPSS 19. Result There were 454 diagnosed and pre-operative cases of gallstones present in the study. There were 120(26.4%) males and 334(73.6%) females, with a mean age of 42.80 ± 12.26 years. Most of the suspects had multiple stones 384 (84.5%) while few had single stones 70(15.4%). Fatty liver was found to be present in 144(31.7%) patients and 92(20.2%) had hepatomegaly. Splenomegaly was present in 16(3.5%) patients. Alkaline phosphatase was elevated in 186(41.0%) patients while SGPT was found to be raised in 160(35.2%). Blood urea nitrogen was found to be elevated in 186(41%) patients and serum creatinine was elevated in 46(10.1%) patients.

Gallstones represent a significant burden for health care systems worldwide and are one of the most common disorders presenting to emergency room. Ultrasonography, complete blood picture test and liver function tests are procedures of choice in suspected gallstones or biliary diseases. They are the most sensitive, specific, non-invasive and inexpensive tests for the detection of gallstones. Our main objective was to evaluate the relationship of ultrasonographic findings, hemolytic indices and liver function tests with gallstones. It was a prospective study carried out in Civil Hospital Karachi (DUHS) and Liaquat National Hospital, two largest tertiary care hospitals of Karachi, Pakistan. Duration of the study was from July 2011 to October 2012. The study was carried out on diagnosed, pre-operative and symptomatic patients of cholelithiases. Exclusion criteria were patients of gallbladder and pancreatic carcinoma, emergency operations, patients having age <12 years and non-cooperative patients, who refused to give written consent for participation in the study. Total two tests were performed on each patient after diagnosis by ultrasonography. These were complete blood count and liver function tests. All the demographic data, laboratory findings and ultrasonographic features were noted in a pre-structured Performa. Sample size was calculated by using open-epidemiological sample size calculator prevalence (p) = 35%, d = 5%, and confidence interval (CI) 95% = 350. All the data was entered and analyzed through SPSS 19. There were 454 diagnosed and pre-operative cases of gallstones present in the study. There were 120(26.4%) males and 334(73.6%) females, with a mean age of 42.80 ± 12.26 years. Most of the suspects had multiple stones 384 (84.5%) while few had single stones 70(15.4%). Fatty liver was found to be present in 144(31.7%) patients and 92(20.2%) had hepatomegaly. Splenomegaly was present in 16(3.5%) patients. Alkaline phosphatase was elevated in 186(41.0%) patients while SGPT was found to be raised in 160(35.2%). Blood urea nitrogen was found to be elevated in 186(41%) patients and serum creatinine was elevated in 46(10.1%) patients. In the light of findings it is recommend that all patients should go through the process of ultrasonography and all the biochemical parameters should be analyzed before surgery.

Can abdominal surgical emergencies be treated in an ambulatory setting?

The performance of emergency abdominal surgery in an outpatient setting is increasingly the order of the day in France. This review evaluates the feasibility and reliability of ambulatory surgical treatment of the most common abdominal emergencies: appendectomy for acute appendicitis and cholecystectomy for acute complications of gallstone disease (acute cholecystitis and gallstone pancreatitis). This study evaluates surgical procedures performed on an ambulatory basis according to the international definition (admission in the morning, discharge in the evening with a hospital stay of less than 12 hours). Just as for elective surgery, eligibility of patients for an ambulatory approach depends on the capacities of the surgical and anesthesia team: to manage the risks, particularly the risk of deferring surgery until the morning); to prevent or treat post-operative symptoms like pain, nausea, vomiting, re-ambulation in order to permit rapid post-operative discharge. Recent studies have shown that appendectomy for non-complicated acute appendicitis can be deferred for up to 12 hours without any increase in danger. Many other studies have shown that early discharge after appendectomy for acute non-complicated appendicitis is feasible and safe. Nonetheless, there is only one published series of truly ambulatory appendectomies. The results were excellent. Patients who presented in the afternoon were brought back for operation the following morning. The appropriate timing for performance of cholecystectomy in patients with acute calculous cholecystitis or gallstone pancreatitis has not been well defined, but is always somewhat delayed relative to the onset of symptoms. To minimize operative complications, cholecystectomy for acute calculous cholecystitis should probably be performed between 24 and 72 hours after diagnosis. Cholecystectomy for gallstone pancreatitis should probably not be delayed longer than a week; the need to keep the patient hospitalized during the interval has not been demonstrated. Early discharge after cholecystectomy was usually possible, even in series where acute cholecystitis was diagnosed intra-operatively. Cholecystectomy for acute cholecystitis and gallstone pancreatitis seems to be feasible but no reports specifically support this approach. Emergency abdominal surgery seems to be feasible on an ambulatory setting for non-complicated acute appendicitis, acute calculous cholecystitis and gallstone pancreatitis. Only a single French series on ambulatory appendectomy for acute appendicitis has been reported. Copyright © 2015. Published by Elsevier Masson SAS.

Postoperative ileus is one of the main complications in the postoperative period. New measures appeared with the introduction of «fast-track surgery» to accelerate recovery: coffee, chewing gum and gastrograffin. We performed a summary of current evidence, reviewing articles from MEDLINE, Cochrane Database of Systematic Reviews, ISI Web of Science, and SCOPUS databases. Employed search terms were «postoperative ileus» AND («definition» OR «epidemiology» OR «risk factors» OR «Management»). We selected 44 articles: 9 systematic reviews 11 narrative reviews, 13 randomized clinical trials, 6 observational studies, and the remaining 5 scientific letters, assumptions, etc. There is little literature about this topic, studies are heterogeneous, with disparity in the results. In addition, they only focus on colorectal and gynecological surgery. New high-quality studies are needed, preferably randomized clinical trials, in order to clarify the usefulness of these measures.

We present the results of an electron paramagnetic resonance (EPR) study of mixed cholesterol gallstones. We have established that free radicals are distributed nonuniformly within the interior of the stone. The type and number of paramagnetic centers depend on the pigment content in the selected layer. We show that the parameters of the sextet lines in the EPR spectrum of the pigment are close to the parameters of lines in the spectrum of a brown pigment stone.

Background Cholesterol gallstone disease is a complex genetic trait and induced by multiple but as yet unknown genes. A major Lith gene, Lith1 was first identified on chromosome 2 in gallstone-susceptible C57L mice compared with resistant AKR mice. Abcb11, encoding the canalicular bile salt export pump in the hepatocyte, co-localizes with the Lith1 QTL region and its hepatic expression is significantly higher in C57L mice than in AKR mice. Material and methods To investigate whether Abcb11 influences cholesterol gallstone formation, we created an Abcb11 transgenic strain on the AKR genetic background and fed these mice with a lithogenic diet for 56 days. Result We excluded functionally relevant polymorphisms of the Abcb11 gene and its promoter region between C57L and AKR mice. Overexpression of Abcb11 significantly promoted biliary bile salt secretion and increased circulating bile salt pool size and bile salt-dependent bile flow rate. However, biliary cholesterol and phospholipid secretion, as well as gallbladder size and contractility were comparable in transgenic and wild-type mice. At 56 days on the lithogenic diet, cholesterol saturation indexes of gallbladder biles and gallstone prevalence rates were essentially similar in these two groups of mice. Conclusion Overexpression of Abcb11 augments biliary bile salt secretion, but does not affect cholelithogenesis in mice. PMID:20456485

Gallbladder is one of the most commonly encountered specimen in a pathology laboratory. A diverse spectrum of diseases affect the biliary system, often presenting with similar clinical signs and symptoms. We aimed to define the profile of gallbladder diseases in our region, and to determine potential correlations between histopathologic features we observed. We reviewed all cholecystectomies processed in Department of Pathology of Afyon Kocatepe University Hospital between January 2000 and March 2008. Gross and histopathologic features of the specimens were reevaluated. Among 1500 patients; 69.9% were women and 30.1% were men. We found out fourteen primary gallbladder carcinomas (0.93%) with adenocarcinomas being the most frequent type (78.57%). The rate of cholelithiasis was found as 89.9%. The most common type of gallstones was mixed cholesterol type gallstones with 67.5% followed by black pigment and brown pigment types as 23.83% and 5.89%, respectively. The association of metaplasia with dysplasia and also gallstones were statistically significant (p < 0.001, p < 0.005). The rate of the gallbladder polyps was 2.6% with the cholesterol polyps being the most common type (56.4%). Gallbladder diseases often present with similar clinical signs and symptoms and a surgical pathologist should be alert especially of precancerous lesions. With our results, we also conclude that elderly women with longstanding gallstone disease should undergo elective surgery even when no symptoms are present.

AIM: Gallstone disease is increasing in sub-saharan Africa (SSA). In the west, the majority of stones can be dissolved with bile salts, since the major component is cholesterol. This medical therapy is expensive and not readily accessible to poor populations of SSA. It was therefore necessary to analyze the chemical composition of biliary stones in a group of patients, so as to make the case for introducing bile salt therapy in SSA. METHODS: All patients with symptomatic gallstones were recruited in the study. All stones removed during cholecystectomy were sent to Houston for x-ray diffraction analysis. Data on age, sex, serum cholesterol, and the percentage by weight of cholesterol, calcium carbonate, and amorphous material in each stone was entered into a pre-established proforma. Frequencies of the major components of the stones were determined. RESULTS: Sixteen women and ten men aged between 27 and 73 (mean 44.9) years provided stones for the study. The majority of patients (65.38%) had stones with less than 25% of cholesterol. Amorphous material made up more than 50% and 100% of stones from 16 (61.53%) and 9 (34.61%) patients respectively. CONCLUSION: Cholesterol is present in small amounts in a minority of gallstones in Yaounde. Dissolution of gallstones with bile salts is unlikely to be successful. PMID:14716845

AIM: To simultaneously evaluate the presence of defects in gallbladder and gastric emptying, as well as in intestinal transit in gallstone patients (GS) and the effect of chronic ursodeoxycholic acid (UDCA) administration on these parameters and on serum bile acids and clinical outcome in GS and controls (CTR). METHODS: After a standard liquid test meal, gallbla-dder and gastric emptying (by ultrasound), oroileal transit time (OITT) (by an immunoenzymatic technique) and serum bile acids (by HPLC) were evaluated before and after 3 mo of UDCA (12 mg/kg bw/d) or placebo administration in 10 symptomatic GS and 10 matched healthy CTR. RESULTS: OITT was longer in GS than in CTR (P < 0.0001); UDCA significantly reduced OITT in GS (P < 0.0001), but not in CTR. GS had longer gastric half-emptying time (t1/2) than CTR (P < 0.0044) at baseline; after UDCA, t1/2 significantly decreased (P < 0.006) in GS but not in CTR. Placebo administration had no effect on gastric emptying and intestinal transit in both GS and CTR. CONCLUSION: The gallstone patient has simultaneous multiple impairments of gallbladder and gastric emptying, as well as of intestinal transit. UDCA administration restores these defects in GS, without any effect in CTR. These results confirm the pathogenetic role of gastrointestinal motility in gallstone disease and suggest an additional mechanism of action for UDCA in reducing bile cholesterol supersaturation.

Gallbladder disease is highly related to inflammation, but the inflammatory processes are not well understood. Bile provides a direct substrate in assessing the local inflammatory response that develops in the gallbladder. To assess the reproducibility of measuring inflammatory markers in bile, we designed a methods study of 69 multiplexed immune-related markers measured in bile obtained from gallstone patients. To evaluate assay performance, a total of 18 bile samples were tested twice within the same plate for each analyte, and the 18 bile samples were tested on two different days for each analyte. We used the following performance parameters: detectability, coefficient of variation (CV), intraclass correlation coefficient (ICC), and percent agreement (concordance among replicate measures above and below detection limit). Furthermore, we examined the association of analyte levels with gallstone characteristics such as type, numbers, and size. All but 3 analytes (Stem Cell Factor, SCF; Thrombopoietin, TPO; sIL-1RI) were detectable in bile. 52 of 69 (75.4%) analytes had detectable levels for at least 50% of the subjects tested. The within-plate CVs were ⩽25% for 53 of 66 (80.3%) detectable analytes, and across-plate CVs were ⩽25% for 32 of 66 (48.5%) detectable analytes. Moreover, 64 of 66 (97.0%) analytes had ICC values of at least 0.8. Lastly, the percent agreement was high between replicates for all of the analytes (median; within plate, 97.2%; across plate, 97.2%). In exploratory analyses, we assessed analyte levels by gallstone characteristics and found that levels for several analytes decreased with increasing size of the largest gallstone per patient. Our data suggest that multiplex assays can be used to reliably measure cytokines and chemokines in bile. In addition, gallstone size was inversely related to the levels of select analytes, which may aid in identifying critical pathways and mechanisms associated with the pathogenesis of gallbladder diseases.

Elderly male patients are thought to have a higher incidence of biliary infections. This demographic is common among veterans, so we analyzed the spectrum of gallstone disease in a large veteran population. A total of 285 patients with gallstone disease were studied. There were 27 women and 258 men, with an average age of 62 years. Gallstones, bile, and blood (as indicated) were cultured. Illness severity was staged as none (no clinical infection), moderate (fever, leukocytosis), or severe (cholangitis, bacteremia, abscess, hypotension, organ failure). Gallstones were grouped by appearance. Three bacterial groups were defined: EK (Escherichia coli or Klebsiella species), N (Enterococcus), or Oth (all other species). Biliary bacteria were present in 145 (51%) patients. Bacterial presence by patient age was 33% for those less than 50 years, 48% for those 50 to 70 years, and 65% for those more than 70 years (P <.02 vs. others). Bacterial presence by stone type was as follows: cholesterol, 11%; mixed, 51%; pigment, 71% (P <.01 vs. others). Illness severity by stone type was as follows for cholesterol: none, 73%; moderate, 27%; severe, 0%; for mixed: none, 62%; moderate, 25%; severe, 13%; for pigment: none, 41%; moderate, 17%; severe, 41% (P <.0001 vs. others). Illness severity by bacterial group was as follows for sterile: none, 77%; moderate, 23%; severe, 0%; for the Oth group: none, 57%; moderate, 22%; severe, 20%; for the N group: none, 32%; moderate, 16%; severe, 52%; for the EK group: none, 18%; moderate, 22%; severe, 60% (P <.0001 vs. sterile/Oth, P = .126 vs. N). Bacterial biliary tree colonization is prevalent in the veterans' population, it increases with age, and is more common with pigment stones. But not all bacterial species cause infectious manifestations. Patients with E coli and/or Klebsiella species commonly showed infectious manifestations, patients with Enterococcus were in an intermediate range, and those with other species had few infectious manifestations.

The aim of present study was to compare the effects of very low calorie diets - protein rich and dietary fiber rich food based - on gallstones formation during rapid weight loss. 68 patients were involved into the study. The body weight index in all cases exceeding normal value and equaled to 35±4,7 kg/m2. For weight correction purposes during 5 weeks the patients in first group were kept on a 520-800 kcal diet of "Margi" food products, prepared according our technology, and in the second group on a protein rich diet of the same calorie content. The body weight and changes in the gall-bladder wall and content were assessed by sonography before starting the diet, after three weeks from the commencement of the diet and upon its completion. The measurement of the body weight after completion of the 5 week diet revealed decrease by 10.9±1,5kg in the first group and by 11,2±1,1kg in the second group. Sonography disclosed growth in the amount of biliary sludge in 3 cases in the first group and in 9 cases in the second group. The statistical analyses of results indicate successful and nearly equal reduction of body weight by means of dietary fiber rich and protein rich diet, but high fiber consumption showed statistically significant benefits for prevention of biliary slug accumulation. The study showed that, in the respect to weight loss, diets based on fiber rich and protein rich food are equal, but fiber rich diet has considerable privilege in prevention of gallstone disease. Our findings support the presence of known association between increased dietary fiber consumption and reduction of gallstone formation. Obesity and rapid weight loss are risk factors for development of gallstones. Taking in an account the beneficial effect of dietary fiber, the food rich with this nutrient, particularly low-calorie fiber rich food "Margi", can be recommended for rapid weight loss in obese patients.

Volvulus caused by mesenteric masses is rare and may result in serious consequences. This study aimed to better characterize volvulus caused by mesenteric masses in children. A retrospective study was conducted in 24 patients who underwent surgical treatment between January 1994 and January 2014 in one single institution. There were 10 boys and 14 girls. The most frequent findings were abdominal pain (100%), emesis (91.7%) and nausea (83.3%). Physical examination showed positive ileus signs in majority cases, and palpable mass was found in half of the patients. Ultrasound and CT scans revealed mesenteric masses in 21 and 24 patients, and 'whirlpool sign' was observed in 19 and 22 patients, respectively. Emergency laparotomy was performed in all patients. Histological examination revealed that 18 cystic masses were lymphangioma, 5 solid cases were lipoma and the remaining one was lipoblastoma. The postoperative course was uneventful in 22 patients, and postoperative obstruction and incision infection occurred in 2 patients. There was no evidence of recurrence at follow-up. Volvulus caused by mesenteric masses is a rare but potentially life-threatening cause of abdominal pain, which should be considered in the differential diagnosis of paediatric acute abdominal pain.

The appearance of gastrografin in colon within 6 hours after gastric administration rules out the need of surgery in abdominal subileus. This diagnostic management is not routinely applied in children. We present a one-year experience from the department of pediatric surgery. Between April 2006 and September 2007 children with symptoms of ileus without clear indications for surgery were subjected to the study. Naso-gastric tube was inserted and 20-100 cc of gastrografin was administered. Abdominal radiograph was taken within 4-6 hours. The presence of contrast in colon allowed for conservative management. All remaining children were subjected to surgery. Newborns and children with intussusception or incarcerated hernia were ruled out of the study. The study was implemented in 8 girls and 7 boys ranking in the age between 1 and 17 (mean 11) years. Thirteen children had postoperative obstruction (8 after appendectomy, 5 after other laparotomy). Two children (with Crohn disease and Schoenlein-Henoch purpura) were not operated before. Four children without appearance of contrast in colon were operated. None of the remaining eleven children required surgical intervention. This management is safe and effective. It brings forward decision for surgery and shortens observation in children who don't require surgical intervention.

　Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

Time Is Not Always the Matter: An Instance of Encapsulating Peritoneal Sclerosis Developing in a Patient on Peritoneal Dialysis for a Short Term.

Encapsulating peritoneal sclerosis (EPS) is an infrequent but serious complication that is observed mostly in patients on long-term peritoneal dialysis (PD). However it can occur after short-term PD, in association with "second hit" risk factors such as peritonitis, acute cessation of PD, or kidney transplantation with the use of calcineurin inhibitors.In our case, a young woman with second-hit risk factors presented with clinical and abdominal computed tomography findings consistent with EPS after short-term PD. She was treated conservatively with nutritional support and was discharged in improved and stable clinical status.In general, the diagnosis of EPS requires clinical findings of bowel obstruction combined with typical computed tomography imaging features. However, the clinical manifestations can be very vague, and the diagnosis is often unclear. A recent study categorized EPS into 4 clinical stages, from pre-EPS to chronic ileus, with associated management from conservative treatment to surgical intervention.In association with second-hit risk factors, EPS can occur after short-term PD. Severity is variable, and the outcome is often devastating. Timely recognition and expert management of EPS can change the outcome very favorably.

Background Abdominal surgery results in a molecular and cellular inflammatory response in the intestine, leading to postoperative ileus. It was hypothesised that resident macrophages within the intestinal muscularis have an important role in this local inflammation. Aims To investigate whether chemical or genetic depletion of resident muscularis macrophages would lead to a reduction in the local inflammation and smooth‐muscle dysfunction. Methods Two rodent models were used to deplete and inactivate macrophages: (1) a rat model in which resident macrophages were depleted by chlodronate liposomes; (2) a model of mice with osteopetrosis mice, completely lacking the resident muscularis macrophages, used as an additional genetic approach. Animals with normal or altered intestinal macrophages underwent surgical intestinal manipulation. The inflammatory response was investigated by quantitative reverse transcriptase‐polymerase chain reaction for mRNA of MIP‐1α, interleukin (IL)1β, IL6, intracellular adhesion molecule 1 (ICAM‐1) and monocyte chemotractant protein 1 (MCP)‐1 in the isolated small bowel muscularis. In addition, muscularis whole mounts were used for histochemical and immunohistochemical analysis to quantify leucocyte infiltration and detect cytokine expression. Subsequently, in vitro muscle contractility and in vivo gastrointestinal transit were measured. Results Both models resulted in markedly decreased expression of MIP‐1α, IL1β, IL6, ICAM‐1 and MCP‐1 after manipulation compared with controls. In addition to this decrease in inflammatory mediators, recruitment of leucocytes into the muscularis was also diminished. Macrophage‐altered animals had near normal in vitro jejunal circular muscle function and gastrointestinal transit despite surgical manipulation. Conclusions Resident intestinal muscularis macrophages are initially involved in inflammatory responses resulting in postoperative ileus. Depletion and inactivation of the muscularis macrophage network prevents postoperative ileus. PMID:16809419

There is no consensual definition of postoperative ileus (POI), which leads to a lack of reproducibility. The aims of this study were (i) to propose and evaluate a classification of postoperative ileus based on its consequences and (ii) to assess the reproducibility of the classification. A national global survey was carried out according to the DELPHI method in order to create a classification of primary POI. The classification was subsequently tested on a cohort of patients who underwent colorectal surgery. Finally, a reproducibility test was performed in five teaching hospitals with junior and senior surgeons. A five-stage classification was proposed: grade A (least) to grade E (worst). For better differentiation, subcategories (D1/D2) were included. Overall, 173 patients were included who underwent colorectal surgery. Forty of them experienced primary postoperative ileus (23.1%). Grade A occurred in 10 cases, grade B in 10 cases, grade C in 14 cases, grade D1 in 2 cases, and grade D2 in 2 cases. POI-related death (grade E) occurred in 2 cases. Patients with grade A POI recovered their gastrointestinal function significantly faster than those with higher grades (p = 0.01), and were more likely to undergo laparoscopic surgery (p = 0.04). The Intraclass Correlation Coefficient (ICC) was 0.83 in the overall population, and 0.83 and 0.82 respectively in the junior and senior surgeon populations. This classification is easy to both use and reproduce. It will improve the reproducibility, evaluation, and assessment of POI. These preliminary results should be confirmed in a multi-centric international study.

We investigated the efficacy of electroacupuncture in reducing the duration of postoperative ileus and hospital stay after laparoscopic surgery for colorectal cancer. We performed a prospective study of 165 patients undergoing elective laparoscopic surgery for colonic and upper rectal cancer, enrolled from October 2008 to October 2010. Patients were assigned randomly to groups that received electroacupuncture (n = 55) or sham acupuncture (n = 55), once daily from postoperative days 1-4, or no acupuncture (n = 55). The acupoints Zusanli, Sanyinjiao, Hegu, and Zhigou were used. The primary outcome was time to defecation. Secondary outcomes included postoperative analgesic requirement, time to ambulation, and length of hospital stay. Patients who received electroacupuncture had a shorter time to defecation than patients who received no acupuncture (85.9 ± 36.1 vs 122.1 ± 53.5 h; P < .001) and length of hospital stay (6.5 ± 2.2 vs 8.5 ± 4.8 days; P = .007). Patients who received electroacupuncture also had a shorter time to defecation than patients who received sham acupuncture (85.9 ± 36.1 vs 107.5 ± 46.2 h; P = .007). Electroacupuncture was more effective than no or sham acupuncture in reducing postoperative analgesic requirement and time to ambulation. In multiple linear regression analysis, an absence of complications and electroacupuncture were associated with a shorter duration of postoperative ileus and hospital stay after the surgery. In a clinical trial, electroacupuncture reduced the duration of postoperative ileus, time to ambulation, and postoperative analgesic requirement, compared with no or sham acupuncture, after laparoscopic surgery for colorectal cancer.

The aim of this study was to construct an electronic bowel sound recording system and determine its usefulness for the diagnosis of appendicitis, mechanical ileus and diffuse peritonitis. A group of 67 subjects aged 17 to 88 years including 15 controls was examined. Bowel sounds were recorded using an electret microphone placed on the right side of the hypogastrium and connected to a laptop computer. The method of adjustable grids (converted into binary matrices) was used for bowel sounds analysis. Significantly, fewer (p ≤ 0.05) sounds were found in the mechanical ileus (1004.4) and diffuse peritonitis (466.3) groups than in the controls (2179.3). After superimposing adjustable binary matrices on combined sounds (interval between sounds <0.01 s), significant relationships (p ≤ 0.05) were found between particular positions in the matrices (row-column) and the patient groups. These included the A1_T1 and A1_T2 positions and mechanical ileus as well as the A1_T2 and A1_T4 positions and appendicitis. For diffuse peritonitis, significant positions were A5_T4 and A1_T4. Differences were noted in the number of sounds and binary matrices in the groups of patients with acute abdominal diseases. Certain features of bowel sounds characteristic of individual abdominal diseases were indicated. BS: bowel sound; APP: appendicitis; IL: mechanical ileus; PE: diffuse peritonitis; CG: control group; NSI: number of sound impulses; NCI: number of combined sound impulses; MBS: mean bit-similarity; TMIN: minimum time between impulses; TMAX: maximum time between impulses; TMEAN: mean time between impulses.

We previously showed that intestinal inflammation is reduced by electrical stimulation of the efferent vagus nerve, which prevents postoperative ileus in mice. We propose that this cholinergic anti-inflammatory pathway is mediated via alpha7 nicotinic acetylcholine receptors expressed on macrophages. The aim of this study was to evaluate pharmacologic activation of the cholinergic anti-inflammatory pathway in a mouse model for postoperative ileus using the alpha7 nicotinic acetylcholine receptor-agonist AR-R17779. Mice were pretreated with vehicle, nicotine, or AR-R17779 20 minutes before a laparotomy (L) or intestinal manipulation (IM). Twenty-four hours thereafter gastric emptying was determined using scintigraphy and intestinal muscle inflammation was quantified. Nuclear factor-kappaB transcriptional activity and cytokine production was assayed in peritoneal macrophages. Twenty-four hours after surgery IM led to a delayed gastric emptying compared with L (gastric retention: L(saline) 14% +/- 4% vs IM(saline) 38% +/- 10%, P = .04). Pretreatment with AR-R17779 prevented delayed gastric emptying (IM(AR-R17779) 15% +/- 4%, P = .03). IM elicited inflammatory cell recruitment (L(saline) 50 +/- 8 vs IM(saline) 434 +/- 71 cells/mm(2), P = .001) which was reduced by AR-R17779 pretreatment (IM(AR-R17779) 231 +/- 32 cells/mm(2), P = .04). An equimolar dose of nicotine was not tolerated. Subdiaphragmal vagotomy did not affect the anti-inflammatory properties of AR-R17779. In peritoneal macrophages, both nicotinic agonists reduced nuclear factor kappaB transcriptional activity and proinflammatory cytokine production, with nicotine being more effective than AR-R17779. AR-R17779 treatment potently prevents postoperative ileus, whereas toxicity limits nicotine administration to ineffective doses. Our data further imply that nicotinic inhibition of macrophage activation may involve other receptors in addition to alpha7 nicotinic acetylcholine receptor.

Electrical stimulation of the vagus nerve reduces intestinal inflammation following mechanical handling, thereby shortening post-operative ileus in mice. Previous studies in a sepsis model showed that this cholinergic anti-inflammatory pathway can be activated pharmacologically by central administration of semapimod, an inhibitor of p38 mitogen-activated protein kinase. We therefore evaluated the effect of intracerebroventricular (i.c.v.) semapimod on intestinal inflammation and post-operative ileus in mice. Mice underwent a laparotomy or intestinal manipulation 1 h after i.c.v. pre-treatment with semapimod (1 µg·kg(-1) ) or saline. Drugs were administered through a cannula placed in the left lateral ventricle 1 week prior to experimentation. Twenty-four hours after surgery, gastric emptying was measured using scintigraphy, and the degree of intestinal inflammation was assessed. Finally, activation of brain regions was assessed using quantitative immunohistochemistry for c-fos. Intestinal manipulation induced inflammation of the manipulated intestine and significantly delayed gastric emptying, 24 h after surgery in saline-treated animals. Semapimod significantly reduced this inflammation and improved gastric emptying. Vagotomy enhanced the inflammatory response induced by intestinal manipulation and abolished the anti-inflammatory effect of semapimod. Semapimod but not saline induced a significant increase in c-fos expression in the paraventricular nucleus, the nucleus of the solitary tract and the dorsal motor nucleus of the vagus nerve. Our findings show that i.c.v. semapimod reduces manipulation-induced intestinal inflammation and prevented post-operative ileus. This anti-inflammatory effect depends on central activation of the vagus nerve. © 2011 The Authors. British Journal of Pharmacology © 2011 The British Pharmacological Society.

Healthy cows consume large amounts of potassium and a sudden loss in appetite can lead to hypokalemia. The routine method to evaluate potassium homeostasis is the measurement of the extracellular potassium in plasma or serum, but this does not provide information about the intracellular potassium pool. To evaluate potassium homeostasis by comparing the extracellular and intracellular potassium concentration in cows with reduced feed intake and gastrointestinal ileus. Twenty cows 1-3 days postpartum (group 1) and 20 cows with gastrointestinal ileus (group 2). Observational cross-sectional study. Plasma potassium was measured by using an ion-sensitive electrode. Intracellular potassium was measured in erythrocytes and muscle tissue (muscle biopsy) by using inductively coupled plasma optical emission spectroscopy. Cows of group 1 did not have hypokalemia. Overall cows with gastrointestinal ileus were hypokalemic (mean ± SD, 2.9 mmol/L ± 0.78), but potassium concentration in erythrocytes and muscle tissue was not lower than in postpartum cows. Intracellular potassium in erythrocytes varied very widely; group 1: 3497-10735 mg/kg (5559 ± 2002 mg/kg), group 2: 4139-21678 mg/kg (7473 ± 4034 mg/kg). Potassium in muscle tissue did not differ between group 1 (3356 ± 735 mg/kg wet weight) and group 2 (3407 ± 1069 mg/kg wet weight). No association between extracellular and intracellular potassium concentrations was detected. That measurement of plasma potassium concentration is not sufficient to evaluate potassium metabolism of cows. Copyright © 2016 The Authors.

To identify clinical hallmarks associated with recovery of gastrointestinal transit. Impaired gastrointestinal transit or postoperative ileus largely determines clinical recovery after abdominal surgery. However, validated clinical hallmarks of gastrointestinal recovery to evaluate new treatments and readiness for discharge from the hospital are lacking. Gastric emptying and colonic transit were scintigraphically assessed from postoperative day 1 to 3 in 84 patients requiring elective colonic surgery and were compared with clinical parameters. The clinical hallmark that best reflected recovery of gastrointestinal transit was validated using data from a multicenter trial of 320 segmental colectomy patients. Seven of 84 patients developed a major complication with paralytic ileus characterized by total inhibition of gastrointestinal motility and were excluded from further analysis. In the remaining patients, recovery of colonic transit (defined as geometric center of radioactivity ≥2 on day 3), but not gastric emptying, was significantly correlated with clinical recovery (ρ = -0.59, P < 0.001). Conversely, the combined outcome measure of tolerance of solid food and having had defecation (SF + D) (area under the curve = 0.9, SE = 0.04, 95% CI = 0.79-0.95, P < 0.001), but not time to first flatus, best indicated recovery of gastrointestinal transit with a positive predictive value of 93% (95% CI = 78-99). Also in the main clinical trial, multiple regression analysis revealed that SF + D best predicted the duration of hospital stay. Our data indicate that the time to SF + D best reflects recovery of gastrointestinal transit and therefore should be considered as primary outcome measure in future clinical trials on postoperative ileus.(Netherlands National Trial Register, number NTR1884 and NTR222).

The formation of cholesterol gallstones involves very complex imbalances, such as alterations in the secretion of biliary lipids (which involves the ABCG5, ABCG8, ABCB4 and ABCB11 transporters), biochemical and immunological reactions in the gallbladder that produce biliary sludge (mucins), physicochemical changes in the structure of cholesterol (crystallization), alterations in gallbladder motility, changes in the intestinal absorption of cholesterol (ABCG5/8 transporters and Niemann-Pick C1L1 protein) and alterations in small intestine motility. Some of these proteins have been studied at the clinical and experimental levels, but more research is required. In this review, we discuss the results of studies on some molecules involved in the pathophysiology of gallstones that may be future therapeutic targets to prevent the development of this disease, and possible sites for treatment based mainly on the absorption of intestinal cholesterol (Niemann-Pick C1L1 and ABCG5/8 proteins).

Gallbladder stones are a very frequently occurring condition. Despite bile bactericidal activity, many bacteria have been detected inside the gallbladder, and gallstones facilitate their presence. Between 3% and 5% of the patients with Salmonella spp. infection develop the carrier stage, with the bacteria persisting inside the gallbladder, shedding bacteria in their feces without signs of infection. The aim of this study was to isolate bacteria from Colombian patients with gallstones, using standard culturing methods, and to identify Salmonella spp. carriers by molecular techniques. A total of 149 patients (120 female and 29 male) diagnosed with gallstones who underwent cholecystectomy and who did not have symptoms of acute inflammation were included. Gallbladder tissue and bile were cultured and used for DNA extraction and Salmonella spp. hilA gene detection. Of the 149 patients 28 (19%) had positive cultures. Twenty-one (75%) patients with positive cultures were from Medellin's metropolitan area. In this geographical location, the most frequent isolations were Pseudomonas spp. (38%), Klebsiella spp. (23%), and Proteus spp. (9%) in addition to unique cases of other bacteria. In Apartado, the isolates found were Enterobacter cloacae (50%), Raoultella terrigena (32%), and both Enterobacter cloacae and Raoultella terrigena were isolated in one (18%) male patient. Five (3.3%) of the 149 patients had positive polymerase chain reaction (PCR) results for the hilA gene of Salmonella spp., all of whom were female and residents of the Medellín metropolitan area. The gallbladder microbiota variability found could be related to geographical, ethnic, and environmental conditions.

Dietary fibre-rich tender cluster beans (Cyamopsis tetragonoloba; CB) are known to exert beneficial cholesterol lowering influence. We examined the influence of a combination of dietary tender CB and garlic (Allium sativum) in reducing the cholesterol gallstone formation in mice. Cholesterol gallstones were induced in Swiss mice by feeding a high-cholesterol diet (HCD) for 10 wk. Dietary interventions were made with 10 per cent CB and 1 per cent garlic included individually or together along with HCD. A total of 100 mice were divided into five groups of 20 mice each. Dietary CB, garlic and CB+garlic reduced the formation of cholesterol gallstones by 44, 25 and 56 per cent, respectively, lowered cholesterol by 23-48, 16-24, and 24-58 in bile, serum, and liver, respectively. Cholesterol saturation index in bile and cholesterol: phospholipid ratio in circulation and hepatic tissue were significantly lowered by these dietary interventions, with highest beneficial effect from CB+garlic. Activities of hepatic cholesterol metabolizing enzymes were modulated by CB, garlic and CB+garlic. Elevation in lipid peroxides caused by HCD was also countered by these dietary interventions, the combination producing the highest effect. The results showed that the prevention of experimentally induced formation of cholesterol gallstones by dietary CB and garlic was due to decreased biliary cholesterol secretion and increased cholesterol saturation index. In addition of anti-lithogenic effect, dietary CB and garlic in combination had a beneficial antioxidant effect.

ABSTRACT Gallbladder disease is one of the most prevalent gastrointestinal disorders that may result from a complex interaction of genetic and environmental factors. This study examined the association of dietary patterns with gallstone disease among Iranian women. This case-control study was conducted in general teaching hospitals in Tehran, Iran. Participants were 101 female cases and 204 female controls aged 40-65 years who were admitted for problems other than GBD. Dietary patterns were identified using principal components analysis based on food frequency questionnaire. Compared to the control group, cases were less educated, less physically active, and consumed more total energy (p<0.02). Having ≥3 livebirths increased the risk of gallstone by more than 5 times, followed by having rapid weight loss, being single, having familial history of gallstone, and consuming high total energy. Two distinct dietary patterns were identified in women (healthy and unhealthy). After adjustment for several confounding variables, healthy dietary pattern was associated with a decreased risk of gallstone disease (OR=0.14, 95% CI 0.048-0.4) while unhealthy dietary pattern was associated with an increased risk (OR=3.77, 95% CI 1.52-9.36). These findings confirm that dietary pattern approach provides potentially useful and relevant information on the relationship between diet and disease. Identifying risk factors will provide an opportunity for prevention of gallbladder disease in developing countries facing an increased risk of obesity. PMID:25995720

Post-operative ileus (POI) is a serious condition which any horse undergoing abdominal surgery is at risk of developing, leading to increased hospitalisation time and resulting costs. Advances in the understanding of the development of equine POI are mainly based on human and rodent literature, where manipulation-induced inflammation has been identified as a trigger, with activation of resident muscularis externa macrophages playing a crucial role in the pathophysiology. Despite many pharmacological trials in all species, there is no single completely successful treatment for POI, highlighting that the condition is multifactorial in cause and requires a multimodal approach to minimise its incidence. © 2017 EVJ Ltd.

Lung transplantation can be a life-saving measure for people with end-stage lung disease from systemic sclerosis. However, outcomes of lung transplantation may be compromised by gastrointestinal manifestations of systemic sclerosis, which can involve any part of the gastrointestinal tract. Esophageal and gastric disease can be managed by enteral feeding with the use of a gastrojejunal feeding tube. In this report, we describe the clinical courses of 2 lung transplant recipients with systemic sclerosis who experienced severe and prolonged barium-impaction ileus after insertion of a percutaneous gastrojejunal feeding tube.

Cystic fibrosis (CF) is the most frequent monogenic genetic disease, autosomal recessive transmitted, characterized by an impressive clinical polymorphism and appreciative fatal prospective. Liver disease is the second non-pulmonary cause of death in cystic fibrosis, which, with increasing life expectancy, became an important management problem. Predisposing factors like male gender, pancreatic insufficiency, meconium ileus and severe mutation are incriminated to influence the occurrence of cystic fibrosis associated liver disease (CFLD). Our study included 174 patients with CF, monitored in the National Cystic Fibrosis Centre, Timisoara, Romania. They were routinely followed-up by clinical assessment, liver biochemical tests, ultrasound examinations and other methods like transient elastography, biopsy, in selected cases. Sixty-six patients, with median age at diagnosis 4.33 years, diagnosed with CFLD, without significant gender gap. CFLD was frequent in patients aged over eight years, with meconium ileus history, carriers of severe mutations (p=0.002). Pancreatic insufficiency, although present in 75% of patients with CFLD was not confirmed as risk factor, not male gender, in our study. CF children older than eight years, carriers of a severe genotype, with a positive history of meconium ileus, were more likely predisposed to CFLD.

We report a 54-year-old male patient with arteriovenous malformation located at the common bile duct and hereditary hemorrhagic telangiectasia. The patient was treated as gallstone pancreatitis at first. Three days after endoscopic nasobiliary drainage (ENBD) for biliary drainage to subside gallstone pancreatitis, hemobilia was drained from the ENBD tube and the serum hemoglobin level gradually decreased. Cholangioscopy and angiography revealed that hemobilia was due to a small arteriovenous malformation located at the common bile duct. Subsequently, the patient was successfully treated by endovascular intervention.

Endoscopic sphincterotomy is widely being used for the treatment of common bile duct stones. In a small group of patients the gallstones are large in size and, hence, difficult to be extracted after a successful endoscopic sphincterotomy. We used a constant infusion of mono-octanoin through a nasobiliary catheter in nine such patients. This method was successful in partial or complete dissolution of the stones in 74% of the patients. In the remaining 36% of the patients, the stones were noted to be soft allowing easy extraction by crushing.

AIM: To determine long-term outcomes of surgical treatments for patients with constipation and features of colonic pseudo-obstruction. METHODS: Consecutive 42 patients who underwent surgery for chronic constipation within the last 13 years were prospectively collected. We identified a subgroup with colonic pseudo-obstruction (CPO) features, with dilatation of the colon proximal to the narrowed transitional zone, in contrast to typical slow-transit constipation (STC), without any dilated colonic segments. The outcomes of surgical treatments for chronic constipation with features of CPO were analyzed and compared with outcomes for STC. RESULTS: Of the 42 patients who underwent surgery for constipation, 33 patients had CPO with dilatation of the colon proximal to the narrowed transitional zone. There were 16 males and 17 females with a mean age of 51.2 ± 16.1 years. All had symptoms of chronic intestinal obstruction, including abdominal distension, pain, nausea, or vomiting, and the mean duration of symptoms was 67 mo (range: 6-252 mo). Preoperative defecation frequency was 1.5 ± 0.6 times/wk (range: 1-2 times/wk). Thirty-two patients underwent total colectomy, and one patient underwent diverting transverse colostomy. There was no surgery-related mortality. Postoperative histologic examination showed hypoganglionosis or agangliosis in 23 patients and hypoganglionosis combined with visceral neuropathy or myopathy in 10 patients. In contrast, histology of STC group revealed intestinal neuronal dysplasia type B (n = 6) and visceral myopathy (n = 3). Early postoperative complications developed in six patients with CPO; wound infection (n = 3), paralytic ileus (n = 2), and intraabdominal abscess (n = 1). Defecation frequencies 3 mo after surgery improved to 4.2 ± 3.2 times/d (range: 1-15 times/d). Long-term follow-up (median: 39.7 mo) was available in 32 patients; all patients had improvements in constipation symptoms, but two patients needed intermittent medication for management of diarrhea. All 32 patients had distinct improvements in constipation symptoms (with a mean bowel frequency of 3.3 ± 1.3 times/d), social activities, and body mass index (20.5 kg/m2 to 22.1 kg/m2) and were satisfied with the results of their surgical treatment. In comparison with nine patients who underwent colectomy for STC without colon dilatation, those in the CPO group had a lower incidence of small bowel obstructions (0% vs 55.6%, P < 0.01) and less difficulty with long-distance travel (6.7% vs 66.7%, P = 0.007) on long-term follow-up. CONCLUSION: Chronic constipation patients with features of CPO caused by narrowed transitional zone in the left colon had favorable outcomes after total colectomy. PMID:22969211

Background and Objective: Acute gallstone pancreatitis is quite common throughout the globe. Conventionally definitive cholecystectomy has been delayed in index hospital admission. Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. Methods: This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. Results: A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications. Conclusion: Laparoscopic cholecystectomy can be safely performed in selected cases of mild gallstone pancreatitis in order to prevent further attacks of acute pancreatitis and other consequences of delayed treatment. Furthermore it resolves the problem of noncompliance of patients in third world countries where many patients are lost for definitive treatment. PMID:24948988

Acute biliary pancreatitis (ABP) is a severe complication of gallstone disease with considerable mortality, and its recurrence rate is reported as 50-90% for ABP patients who do not undergo cholecystectomy. However, the incidence of and risk factors for recurrent pancreatobiliary complications after the initial improvement of ABP are not well established in the literature. The aims of this study were to determine the risk factors for recurrent pancreatobiliary complications and to compare the outcomes between early (within 2 weeks after onset of pancreatitis) and delayed cholecystectomy in patients with ABP. Patients diagnosed with ABP at Yeungnam University Hospital from January 2004 to July 2016 were retrospectively reviewed. The following risk factors for recurrent pancreatobiliary complications (acute pancreatitis, acute cholecystitis, and acute cholangitis) were analyzed: demographic characteristics, laboratory data, size and number of gallstones, severity of pancreatitis, endoscopic sphincterotomy, and timing of cholecystectomy. Patients were categorized into two groups: patients with recurrent pancreatobiliary complications (Group A) and patients without pancreatobiliary complications (Group B). Of the total 290 patients with ABP (age 66.8 ± 16.0 years, male 47.9%), 56 (19.3%) patients developed recurrent pancreatobiliary complications, of which 35 cases were acute pancreatitis, 11 cases were acute cholecystitis, and 10 cases were acute cholangitis. Endoscopic sphincterotomy and cholecystectomy were performed in 134 (46.2%) patients and 95 (32.8%) patients, respectively. Age, sex, BMI, diabetes, number of stone, severity of pancreatitis, and laboratory data were not significantly correlated with recurrent pancreatobiliary complications. The risk of recurrent pancreatobiliary complications was significantly increased in the delayed cholecystectomy group compared with the early cholecystectomy group (45.5 vs. 5.0%, p < 0.001). Based on the multivariate logistic regression analyses, two factors, size of gallstone less than or equal to 5 mm and delayed cholecystectomy, were found as risk factors associated with recurrent pancreatobiliary complications. The incidence of recurrent pancreatobiliary complications was 19.3% and was significantly increased in patients with size of gallstone less than or equal to 5 mm and in those who underwent delayed cholecystectomy.

A thorough and accurate admission medical record is an important tool in ensuring patient safety during the hospital stay. Surgeons' performance might be affected during night shifts due to sleep deprivation. The aim of the study was to assess the quality of admission medical records during day, evening and night time. A total of 1,000 admission medical records were collected from 2009 to 2013 based equally on four diagnoses: mechanical bowel obstruction, appendicitis, gallstone disease and gastrointestinal bleeding. The records were reviewed for errors by a pre-defined checklist based on Danish standards for admission medical records. The time of dictation for the medical record was registered. A total of 1,183 errors were found in 778 admission medical records made during day- and evening time, and 322 errors in 222 admission medical records from night time shifts. No significant overall difference in error was found in the admission medical records when day and evening values were compared to night values. Subgroup analyses made for all four diagnoses showed no difference in day and evening values compared with night time values. Night time deterioration was not seen in the quality of the medical records.

Although this infection is associated with obstructive jaundice or choledocholithiasis, portal vein thrombosis has not been reported. Here, we report the first case of a 60-year-old man who had both C. sinensis infection and portal vein thrombosis with severe hyperbilirubinemia (75.4 mg/dl). He initially presented with abdominal pain and jaundice. Computed tomography revealed gallstones, common bile duct calculus, and thrombus in the left main branch of the portal vein. A nasobiliary tube was inserted under endoscopic retrograde cholangiography. Cytology of the bile juice revealed many C. sinensis eggs. The abdominal pain and jaundice improved following choledocholithotomy and combination treatment with a chemotherapeutic agent and anti-coagulant. This case suggests that inflammation around the portal vein as a result of C. sinensis infection has the potential to evoke portal vein thrombosis. Such cases should be treated with both a chemotherapeutic agent and anti-coagulant therapy. In conclusion, the possibility of infection with C. sinensis should be considered in patients presenting with hyperbilirubinemia and portal vein thrombosis, particularly in East Asian populations. © 2015 Wiley Periodicals, Inc.

Background & objectives: Dietary fibre-rich tender cluster beans (Cyamopsis tetragonoloba; CB) are known to exert beneficial cholesterol lowering influence. We examined the influence of a combination of dietary tender CB and garlic (Allium sativum) in reducing the cholesterol gallstone formation in mice. Methods: Cholesterol gallstones were induced in Swiss mice by feeding a high-cholesterol diet (HCD) for 10 wk. Dietary interventions were made with 10 per cent CB and 1 per cent garlic included individually or together along with HCD. A total of 100 mice were divided into five groups of 20 mice each. Results: Dietary CB, garlic and CB+garlic reduced the formation of cholesterol gallstones by 44, 25 and 56 per cent, respectively, lowered cholesterol by 23-48, 16-24, and 24-58 in bile, serum, and liver, respectively. Cholesterol saturation index in bile and cholesterol: phospholipid ratio in circulation and hepatic tissue were significantly lowered by these dietary interventions, with highest beneficial effect from CB+garlic. Activities of hepatic cholesterol metabolizing enzymes were modulated by CB, garlic and CB+garlic. Elevation in lipid peroxides caused by HCD was also countered by these dietary interventions, the combination producing the highest effect. Interpretation & conclusions: The results showed that the prevention of experimentally induced formation of cholesterol gallstones by dietary CB and garlic was due to decreased biliary cholesterol secretion and increased cholesterol saturation index. In addition of anti-lithogenic effect, dietary CB and garlic in combination had a beneficial antioxidant effect. PMID:26609039

The two subtypes of pigment gallstones, black and brown stones, differ in chemical composition and pathogenesis. We examined a black bilirubinate stone and a black phosphate stone (which represented opposite ends of the compositional spectrum of black noncarbonate stones), a black carbonate stone, and a brown pigment stone using scanning electron microscopy and microchemical techniques to determine if stone microstructure and microcomposition reflected different patterns of formation. The cross-sectional surfaces of the black bilirubinate and black phosphate stones were smooth and homogenous. Electron probe microanalysis demonstrated high concentrations of sulfur and copper in the center of the black bilirubinate stone; sulfur was in a low valence state consistent with disulfide linkages in proteins. The brown stone was rough-surfaced with lamellated bands on cross-section. The lighter-colored bands in this stone contained virtually all of the detected calcium palmitate, while the darker sections contained much more calcium bilirubinate. Plasma oxygen etching demonstrated a network of protein interdigitating with calcium bilirubinate salts in the black bilirubinate and black phosphate stones but not in the black carbonate or brown stones. Argon ion etching demonstrated that calcium bilirubinate was in a closely packed rod-shaped arrangement in all three black stones but not in the brown stone. We conclude that the marked differences in structure and composition between the black noncarbonate and brown pigment gallstones support the hypothesis that the two major pigment gallstone types form by different mechanisms. In addition, the layered structures of the black carbonate and brown stones suggest that stone growth is affected by cyclic changes in biliary composition.

Metastable and equilibrium phase diagrams for unconjugated bilirubin IXα (UCB) in bile are yet to be determined for understanding the physical chemistry of pigment gallstone formation. Also, UCB is a molecule of considerable biomedical importance because it is a potent antioxidant and an inhibitor of atherogenesis. We employed principally a titrimetric approach to obtain metastable and equilibrium UCB solubilities in model bile systems composed of taurine-conjugated bile salts, egg yolk lecithin (mixed long-chain phosphatidylcholines), and cholesterol as functions of total lipid concentration, biliary pH values, and CaCl2 plus NaCl concentrations. Metastable and equilibrium precipitation pH values were obtained, and average pKa values of the two carboxyl groups of UCB were calculated. Added lecithin and increased temperature decreased UCB solubility markedly, whereas increases in bile salt concentrations and molar levels of urea augmented solubility. A wide range of NaCl and cholesterol concentrations resulted in no specific effects, whereas added CaCl2 produced large decreases in UCB solubilities at alkaline pH values only. UV-visible absorption spectra were consistent with both hydrophobic and hydrophilic interactions between UCB and bile salts that were strongly influenced by pH. Reliable literature values for UCB compositions of native gallbladder biles revealed that biles from hemolytic mice and humans with black pigment gallstones are markedly supersaturated with UCB and exhibit more acidic pH values, whereas biles from nonstone control animals and patients with cholesterol gallstone are unsaturated with UCB.

This study evaluated the physiologic properties of high protein buckwheat flour (PBF) by examining its effects on serum cholesterol and body fat in rats and on cholesterol gallstone formation in mice. Animals were fed experimental diets that contained casein, buckwheat protein extract (BWP), or PBF as a protein source (net protein content 200 g/kg). In experiment 1, consumption of PBF and BWP for 10 d caused 33% and 31% decreases, respectively, in serum cholesterol of rats fed cholesterol-enriched diets when compared with consumption of casein (P < 0.05). Dietary PBF caused a significant decrease in liver cholesterol, whereas dietary BWP caused only a slight decrease (P > 0.05). Fecal excretion of neutral and acidic steroids in the PBF group was significantly higher than those in the BWP and casein groups. In experiment 2, consumption of PBF for 10 d significantly suppressed adipose tissue weight and hepatic activity of fatty acid synthase in rats fed cholesterol-free diets compared with consumption of casein (P < 0.05), whereas that of BWP for this period caused only a slight decrease in adipose tissue weight (P > 0.05). In experiment 3, dietary PBF and BWP significantly decreased the incidence of cholesterol gallstones and lithogenic index in mice fed cholesterol-enriched diets for 27 d, which was associated with increased fecal excretion of acidic steroids. This study demonstrated that PBF has strong activities against hypercholesterolemia, obesity, and gallstone formation, suggesting a potential usefulness of PBF as functional ingredient.

Morpho-functional gastric pre-and post-operative changes in elderly patients undergoing laparoscopic cholecystectomy for gallstone related disease

PubMed Central

2012-01-01

Background Cholecystectomy, gold standard treatment for gallbladder lithiasis, is closely associated with increased bile reflux into the stomach as amply demonstrated by experimental studies. The high prevalence of gallstones in the population and the consequent widespread use of surgical removal of the gallbladder require an assessment of the relationship between cholecystectomy and gastric mucosal disorders. Morphological evaluations performed on serial pre and post – surgical biopsies have provided new acquisitions about gastric damage induced by bile in the organ. Methods 62 elderly patients with gallstone related disease were recruited in a 30 months period. All patients were subjected to the most appropriate treatment (Laparoscopic cholecystectomy). The subjects had a pre-surgical evaluation with: • dyspeptic symptoms questionnaire, • gastric endoscopy with body, antrum, and fundus random biopsies, • histo-pathological analysis of samples and elaboration of bile reflux index (BRI). The same evaluation was repeated at a 6 months follow-up. Results In our series the duodeno-gastric reflux and the consensual biliary gastritis, assessed histologically with the BRI, was found in 58% of the patients after 6 months from cholecystectomy. The demonstrated bile reflux had no effect on H. pylori’s gastric colonization nor on the induction of gastric precancerous lesions. Conclusions Cholecystectomy, gold standard treatment for gallstone-related diseases, is practiced in a high percentage of patients with this condition. Such procedure, considered by many harmless, was, in our study, associated with a significant risk of developing biliary gastritis after 6 months during the postoperative period. PMID:23173777

AIM: To investigate the pattern of mucin expression and concentration in bile obtained during endoscopic retrograde cholangiography (ERC) in relation to gallstone disease. METHODS: Bile samples obtained at ERC from 29 consecutive patients, 17 with and 12 without gallstone disease were evaluated for mucin content by gel filtration on a Sepharose CL-4B column. Dot blot analysis for bile mucin apoproteins was performed with antibodies to Mucin 1 (MUC1), MUC2, MUC3, MUC5AC, MUC5B and MUC6. Staining intensity score (0-3) was used as a measure of antigen expression. RESULTS: MUC1, MUC2, MUC3, MUC5AC, MUC5B and MUC6 were demonstrated in 34.4%, 34.4%, 51.7%, 51.7%, 55.1% and 27.5% of bile samples, respectively. The staining intensity scores were 0.62 ± 0.94, 0.58 ± 0.90, 0.79 ± 0.97, 1.06 ± 1.22, 1.20 ± 1.26 and 0.41 ± 0.73, respectively. Mean mucin concentration measured in bile by the Sepharose CL-4B method was 22.8 ± 24.0 mg/mL (range 3.4-89.0 mg/mL). Mean protein concentration was 8.1 ± 4.8 mg/mL (range 1.7-23.2 mg/mL). CONCLUSION: High levels of MUC3, MUC5AC and MUC5B are expressed in bile aspirated during ERC examination. A specific pattern of mucin gene expression or change in mucin concentration was not found in gallstone disease. PMID:19452580

Endoscopic biliary sphincterotomy (EBS) results in permanent loss of sphincter function and its long-term complications are unknown. Endoscopic papillary balloon dilation (EPBD) is an alternative procedure that preserves sphincter function, although it is associated with a higher risk of pancreatitis than is EBS. The aim of this study was to evaluate the safety and outcomes of EPBD with limited indications for removal of common bile duct (CBD) stones combined with gallstones in patients younger than 40 years. Young (age < 40 years) patients who had CBD stones combined with gallstones on imaging studies were enrolled in this study. A total of 132 patients were randomly divided into the EPBD group (n = 62) or the EBS group (n = 70) for extraction of CBD stones. The ballooning size of EPBD ranged from 6 to 10 mm. Complete bile duct clearance was achieved in 98.4 % (61/62) of the EPBD group and 100 % (70/70) of the EBS group. Mechanical lithotripsy was required in 8.1 % (5/62) of the EPBD group and 8.6 % (6/70) of the EBS group. The early complication rates were 8.1 % (5/62) (five pancreatitis) in the EPBD group and 11.4 % (8/70) (five [7.1 %] pancreatitis, two bleeding and one perforation) in the EBS group. The recurrence rates of CBD stones were 1.6 % (1/62) in the EPBD group and 5.7 % (4/70) in the EBS group. EPBD with limited indications was safe and effective as EBS for removal of CBD stones combined with gallstones in young patients who had a longer life expectancy.

Cholelithiasis is the second cause of hospital admissions in Chile. To study the prevalence of symptomatic gallstone disease and opportunity of cholecystectomy in La Florida, Santiago and among Mapuche Indians in Huapi Island. In the period 2000-2001, we contacted to 71% (1127 subjects) and to 61% (145 subjects) patients of La Florida and Huapi Island, respectively, that had previously participated in an epidemiological study on cholelithiasis in 1993. We defined symptomatic gallstone patients as those with a history of biliary colic. Each patient was subjected to gallbladder ultrasound. In 1993, 30-35% of gallstone patients were symptomatic (approximately 70% women). During the lapse 1993-2001, only 50% of subjects from La Florida and 25% of patients from Huapi Island were cholecystectomized (p < 0.05). Fifty percent of cholecystectomies were emergency operations. In 38 symptomatic Mapuche Indians from Huapi, cholecystectomy was indicated in 2001. After five months of the indication, only one of these subjects had been operated. Laparoscopic cholecystectomy represented 40% of all cholecystectomies performed in the National Health Service Hospitals. This study demonstrates an unacceptable high prevalence of symptomatic gallstone patients remaining non-operated in both the urban and rural communities. This reciprocally correlates with the high frequency of emergency cholecystectomies and the high incidence of gallbladder cancer among Chileans. This study contrasts negatively with the situation of Scotland, where 73.5% of cholecystectomies were laparoscopic in 1998-1999. To reach Scotland standards, the Chilean Public Health System should increase the number of cholecystectomies from 27,000 in 2001 to 57,510

Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan. Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. Ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.

During laparoscopic cholecystectomy, a large stone burden may cause difficulty when extracting the gallbladder through the abdominal wall. Currently, the alternatives available to the surgeon include increasing the incision, removing stones singly, or utilizing complex fragmentation techniques like the pulsed dye laser. We have employed an electromechanical rotary gallstone lithotrite (RGL) to fragment stones to an aspiratable size. Initially, cholesterol spheres were pulverized in a latex balloon to demonstrate the efficacy of the device. Then, human gallstones were placed in the balloon and reduced to fragments less than or equal to 1 mm from initial sizes of 4-24 mm. Human stones were then inserted in ex vivo porcine gallbladders in a controlled experiment and treated with the device. Ten out of 12 tests were completed within 30 s; one test required 49 s and one 105 s to achieve complete fragmentation. Blinded histological evaluation demonstrated that tissue abrasion caused by use of the device would not interfere with the diagnosis of unsuspected malignancy. Clinical trials have now commenced under the auspices of the hospital ethical committee.

Inflammatory reactions are par- tially responsible for postoperative ileus (POI). Serum C-reactive protein (CRP) is an acknowledged marker of inflammation. In this study the CRP response with respect to POI in elective colorectal surgery was exam- ined to define the role of serum CRP as an early predic- tor of POI. Three hundred eighty-three patients who underwent elective colorectal resection were identified for inclusion in this study. We defined early POI as that occurring within 30 days following the surgery. Thirty-five patients with POI were com- pared to a subgroup of 348 patients with an unevent- ful postoperative course, and the correlation between postoperative serum CRP levels and POI in colorectal surgery was investigated. In the univariate analysis, length of operation, surgical blood loss, and serum CRP were factors significantly associated with POI following colorectal surgery; however, these fac- tors lost their significance on multivariate analysis. Our results suggest that an increase in CRP levels alone is not a predictor for POI following surgery for colorectal surgery. Although inflammatory responses are known to contribute to the ileus, ad- ditional study is required to identify risk factors that would be more useful for prediction of POI.

To investigate the efficacy and safety of alvimopan, 12 mg, administered orally 30 to 90 minutes preoperatively and twice daily postoperatively in conjunction with a standardized accelerated postoperative care pathway for managing postoperative ileus after bowel resection. This multicenter, randomized, placebo-controlled, double-blind, phase 3 trial enrolled adult patients undergoing partial bowel resection with primary anastomosis by laparotomy and scheduled to receive intravenous, opioid-based, patient-controlled analgesia. A standardized accelerated postoperative care pathway including early ambulation, oral feeding, and postoperative nasogastric tube removal was used to facilitate gastrointestinal (GI) tract recovery in all of the patients. The primary end point was time to GI-2 recovery (toleration of solid food and first bowel movement). Secondary end points included time to GI-3 recovery (toleration of solid food and first flatus or bowel movement), hospital discharge order written, and actual hospital discharge. Postoperative length of hospital stay based on calendar day of hospital discharge order written, opioid consumption, and overall postoperative ileus-related morbidity were recorded. Alvimopan, 12 mg, was well tolerated and significantly accelerated GI-2 recovery, GI-3 recovery, and actual hospital discharge compared with a standardized accelerated postoperative care pathway alone (hazard ratio = 1.5, 1.5, and 1.4, respectively; P < .001 for all). Time to hospital discharge order written as measured by hazard ratio (1.4) and by postoperative calendar days (mean for alvimopan, 5.2 days; mean for placebo, 6.2 days) was also accelerated. Opioid consumption was comparable between groups, and alvimopan was associated with reduced postoperative ileus-related morbidity compared with placebo. Alvimopan, 12 mg, administered 30 to 90 minutes before and twice daily after bowel resection is well tolerated, accelerates GI tract recovery, and reduces postoperative ileus-related morbidity without compromising opioid analgesia.

Vedolizumab is a biologic, which inhibits leukocyte adhesion in the gut and is used to treat ulcerative colitis (UC) and Crohn's disease (CD). Little is known of the surgical outcomes in patients treated with vedolizumab. We reviewed the postoperative complications in a cohort of pediatric UC and CD patients treated with vedolizumab. We identified pediatric UC and CD patients treated with vedolizumab at our institution from 2014 to 2016. We compared postoperative outcomes in the vedolizumab exposed group to a cohort of vedolizumab naïve patients who required diverting ileostomy. Of the 31 patients who were treated with vedolizumab, 13 patients required surgery. Eight of 13 (62%) vedolizumab exposed patients had a postoperative complication, including mucocutaneous separation at the stoma (3), readmission for pain/dehydration (2), bowel obstruction at the ostomy, and intraoperative colonic perforation. In comparison, four of 16 (25%) vedolizumab naive patients had a postoperative complication, including readmission for ileus and for high stoma output with mucocutaneous separation. p=0.07. At our institution, patients treated with vedolizumab prior to surgery have a high prevalence of postoperative complications, notably mucocutaneous separation of the stoma. A prospective, multicenter study is needed to determine if these observed complications are attributable to vedolizumab. Level III. Copyright © 2018 Elsevier Inc. All rights reserved.

To describe the clinical course, management, and outcome of a horse with a presumptive diagnosis of botulism treated with long-term mechanical ventilation. A 6-year-old Quarter Horse gelding with a history of esophageal obstruction was evaluated for progressive tetraparesis. Generalized and progressive skeletal muscle weakness characterized by recumbency, decreased tongue, tail, eyelid, and anal tone, and respiratory failure was observed. Anticholinergic signs including decreased salivation, xerophthalmia, and ileus were also noted. A presumptive diagnosis of botulism was made, although mouse inoculation and spore identification testing were negative. Pentavalent botulism antitoxin was administered on Day 3. The horse was maintained on a water mattress and was managed with mechanical ventilation for 2 weeks. Complications encountered included necrotic rhinitis, intertrigo, decubital ulceration, jugular and cephalic vein thrombophlebitis, corneal ulceration, and transient ventricular tachycardia. The horse showed marked improvement in skeletal muscle strength and parasympathetic nervous system function, allowing it to be successfully weaned from the ventilator but suffered large colon volvulus on Day 21 and was euthanized. To the authors' knowledge, this is the first report of successful weaning from long-term mechanical ventilation and management of recumbency using a water mattress in an adult horse with presumptive botulism. © Veterinary Emergency and Critical Care Society 2014.

AIM: To investigate the prevalence and risk factors of polypoid lesions of the gallbladder (PLGs) in petrochemical employees in Ningbo, Zhejiang Province, China. METHODS: All active and retired employees aged 20-90 years (n = 11098) of a refinery and chemical plant in eastern China were requested to participate in a health survey. The participants were subjected to interview, physical examination, laboratory assessments and ultrasonography. All the participants were invited to have a physical examination after a face-to-face interview. Fasting blood samples were obtained from the antecubital vein, and the samples were used for the analysis of biochemical values. Abdominal ultrasonography was conducted. RESULTS: A total of 10461 (7331 men and 3130 women) current and former petrochemical employees attended for screening. The overall prevalence of post-cholecystectomy, gallstones and PLGs was 0.9%, 5.2% and 7.4%, respectively. Compared with the increased prevalence of either gallstones or post-cholecystectomy in older persons, PLGs were more common in the middle-aged, peaking in those aged 40-59 years. Excluding the patients with gallstones, gallstones mixed with PLGs, or those who had undergone cholecystectomy, in the remaining 9828 participants, the prevalence of PLGs in men (8.9%) was significantly higher than that in women (5.5%, P < 0.001). The analyzed risk factors with increased OR for the development of PLGs were male gender (OR = 1.799, P < 0.001), age ≥ 30 years (OR = 2.699, P < 0.001) and hepatitis B surface antigen (HBsAg) positivity (OR = 1.374, P = 0.006). CONCLUSION: PLGs are not rare among Chinese petrochemical employees. Male gender, HBsAg positivity, and middle age are risk factors for developing PLGs. PMID:23885152

Gallstones and common bile duct calculi have been increasingly diagnosed in recent years in infants and children. The present study aims to review the spectrum of this disorder in the last two decades. During the period 1979-96 a total of 102 consecutive infants and children were diagnosed in Royal Alexandra Hospital for Children with gallstones or common bile duct calculi. A detailed retrospective analysis and follow-up of these children form the basis of the present report. The median age at presentation was 10 years. Recurrent right upper quadrant pain was the most common clinical presentation. The male-to-female ratio was 3:2 and this male predominance was noted in all the age groups. Aetiologically three identifiable groupings were noted: idiopathic disease (n = 66), haematological diseases (n = 23) and specific non-haematological disease (n = 13). The incidence of idiopathic and haematological stones had increased two-fold in the second half of the study. The majority of children (86%) underwent surgical correction. Choledocholithiasis (CDL) was noted in 18 children (18%). Jaundice was commonly associated with abdominal pain in this group. A higher incidence of common bile duct calculi was noted in females and children less than 5 years of age (P < 0.01). Common bile duct calculi were accurately diagnosed by pre-operative imaging in all 18 children. Surgical correction was required in all except two. The present study suggests an increasing incidence of gallstones in children. Cholelithiasis in children occurs commonly in boys, is idiopathic in aetiology and presents with a vague right upper quadrant pain. Choledocholithiasis is not uncommon in children, occurs more commonly in girls aged < 5 years and presents with jaundice or abnormal liver function tests.

Typhoid fever is caused by the human-restricted pathogen Salmonella enterica sv. Typhi. Approximately 5% of people that resolve the disease become chronic carriers, with the gallbladder as the main reservoir of the bacteria. Of these, about 90% present with gallstones, on which Salmonella form biofilms. Because S. Typhi is a human-restricted pathogen, these carriers are the main source of dissemination of the disease; unfortunately, antibiotic treatment has shown to be an ineffective therapy. This is believed to be caused by the inherent antibiotic resistance conferred by Salmonella biofilms growing on gallstones. The gallstone mouse model with S. Typhimurium has proven to be an excellent surrogate for S. Typhi chronic infection. In this study, we test the hypothesis that the biofilm state confers Salmonella with the increased resistance to antibiotics observed in cases of chronic carriage. We found that, in the biofilm state, Salmonella is significantly more resistant to ciprofloxacin, a common antibiotic used for the treatment of Salmonella, both in vitro (p < 0.001 for both S. Typhi and S. Typhimurium with respect to planktonic cells) and in vivo (p = 0.0035 with respect to control mice).

The effect of the type of dietary fat on bile lipids and lithogenicity is unclear. This study compared the effects of two dietary oils that differed in fatty acid profile on biliary lipid composition in humans. Female patients who had cholesterol gallstones and were scheduled for elective cholecystectomy were studied. For 30 d before surgery, subjects were kept on diets that contained olive oil (olive oil group, n = 9) or sunflower oil (sunflower oil group, n = 9) as the main source of fat. Gallbladder bile and stones were sampled at surgery. After cholecystectomy, duodenal samples were collected by nasoduodenal intubation during fasting and after administration of mixed liquid meals that included the corresponding dietary oil. Duodenal and gallbladder bile samples were analyzed for cholesterol, phospholipids, and total bile acids by established methods. Individual bile acid conjugates in gallbladder bile were measured by high-performance liquid chromatography. Gallstones were analyzed by semiquantitative polarizing light microscopy. Despite marked differences in the absolute concentration of biliary lipids and total lipid content, manipulation of dietary fat ingestion did not influence the cholesterol saturation or the profile of individual bile acids in gallbladder bile obtained from patients who had gallstones. All but one subject had mixed cholesterol stones. A cholesterol saturation index of hepatic bile in fasted cholecystectomized patients was similar in both dietary groups and indicative of supersaturation. In response to the test meal, the cholesterol saturation index decreased significantly in patients given the olive oil diet, reaching values lower than one at 120 min postprandially. In contrast, hepatic bile secreted by patients who consumed sunflower oil appeared supersaturated (cholesterol saturation index >1.5) throughout the experiment. Our results suggest that the type of dietary fat habitually consumed can influence bile composition in humans. In gallbladder, this influence was noted in the presence of more concentrated bile in the olive oil group. However, this was not translated into a modification of cholesterol saturation, which is likely due to the fact that cholesterol gallstones were present by the time the dietary intervention started. The finding that a typical postprandial variation in hepatic bile lithogenicity occurred only in olive oil patients was revealing. While keeping in mind the methodologic limitations of this part of the study, some gastrointestinal and metabolic mechanisms for this effect are discussed.

Postoperative ileus following major colorectal surgery.

2018-06-01

Postoperative ileus (POI) is characterized by delayed gastrointestinal recovery following surgery. Current knowledge of pathophysiology, clinical interventions and methodological challenges was reviewed to inform modern practice and future research. A systematic search of MEDLINE and Embase databases was performed using search terms related to ileus and colorectal surgery. All RCTs involving an intervention to prevent or reduce POI published between 1990 and 2016 were identified. Grey literature, non-full-text manuscripts, and reanalyses of previous RCTs were excluded. Eligible articles were assessed using the Cochrane tool for assessing risk of bias. Of 5614 studies screened, 86 eligible articles describing 88 RCTs were identified. Current knowledge of pathophysiology acknowledges neurogenic, inflammatory and pharmacological mechanisms, but much of the evidence arises from animal studies. The most common interventions tested were chewing gum (11 trials) and early enteral feeding (11), which are safe but of unclear benefit for actively reducing POI. Others, including thoracic epidural analgesia (8), systemic lidocaine (8) and peripheral μ antagonists (5), show benefit but require further investigation for safety and cost-effectiveness. POI is a common condition with no established definition, aetiology or treatment. According to current literature, minimally invasive surgery, protocol-driven recovery (including early feeding and opioid avoidance strategies) and measures to avoid major inflammatory events (such as anastomotic leak) offer the best chances of reducing POI. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

Mirizzi syndrome is a complication of gallbladder stones impacted in Hartmann's pouch or cystic duct with compression of the bile duct. The diagnosis is made by imaging studies, although most of them are found through intraoperative surgical findings. Treatment is cholecystectomy and bile duct restoration when needed. to analyze a series of cases of Mirizzi syndrome and compare the results with those published in the literature. We report 4 cases with Mirizzi syndrome in a cohort of 1,034 cases studied in the Hospital Español of Veracruz over 21 years. In our series the frequency of Mirizzi syndrome was 0.38%, the average age was 32.1 ± 58.4 years, 50% were male gender and 25% had jaundice with a demonstrable liver profile. In 1 case, ultrasound suggested Mirizzi syndrome and percutaneous cholangiography and computed tomography confirmed the diagnosis. All patients underwent laparoscopic cholecystectomy, and 2 transcystic cholangiographies were performed. One case was classified as Type I-A and three as type I-B. (Beltran and Csendes). The postoperative evolution was satisfactory in all and no mortality was presented. Mirizzi syndrome should be suspected in patients with gallstones who develop obstructive jaundice and it must be confirmed with imaging studies. The surgeon must take extreme precautions to avoid accidental injury to the bile ducts.

Minimally invasive treatment of cholecysto-choledocal lithiasis: The point of view of the surgical endoscopist.

PubMed

De Palma, Giovanni D

2013-06-27

The rate of choledocholithiasis in patients with symptomatic cholelithiasis is estimated to be approximately 10%-33%, depending on the patient's age. Development of Endoscopic Retrograde Cholangiopancreatography and Laparoscopic Surgery and improvement of diagnostic procedures have influenced new approaches to the management of common bile duct stones in association with gallstones. At present available minimally-invasive treatments of cholecysto-choledocal lithiasis include: single-stage laparoscopic treatment, perioperative endoscopic treatment and endoscopic treatment alone. Published data evidence that, associated endoscopic-laparoscopic approach necessitates increased number of procedures per patient while single-stage laparoscopic treatment is associated with a shorter hospital stay. However, current data does not suggest clear superiority of any one approach with regard to success, mortality, morbidity and cost-effectiveness. Considering the variety of therapeutic options available for management, a critical appraisal and decision-making is required. Endoscopic retrograde cholangiopancreatography/EST should be adopted on a selective basis, i.e., in patients with acute obstructive suppurative cholangitis, severe biliary pancreatitis, ampullary stone impaction or severe comorbidity. In a setting where all facilities are available, decision in the selection of the therapeutic option depends on the patients, the number and size of choledocholithiasis stones, the anatomy of the cystic duct and common bile duct, the surgical history of patients and local expertise.

[Use of antibiotics and nitrofurans in treating acute and chronic cholecystitis].

PubMed

Venger, I K

1984-02-01

Sixty-two patients with acute cholecystitis and 108 patients with chronic calculous cholecystitis were examined. High levels of contamination of the bile, gallbladder mucosa and gallstones were shown. E. coli, Staphylococcus and Streptococcus were most frequent among 20 species of aerobic and anaerobic bacteria. Preoperative sanation of the hepatoduodenal area with antibiotics did not result in complete elimination of the bacteria in the bile, gallbladder mucosa and gallstones. The use of nitrofurans and especially furazolidone and furagin in the preoperative period prevented the microbial growth in the specimens collected during the operations. The data of the study allow recommending the use of furazolidone and furagin for preoperative sanation of the biliferous tract.

A method for the simultaneous determination of eight kinds of conjunct bile acids in human bile was developed by HPLC. They were separated on a YWG-C18 (3 microns) column at 30 degrees C, with methanol/water (65/35, V/V, pH3.0) as mobile phase, and detection wavelength at UV 210 nm. The linear ranges were 50-1,000 microns.ml-1, the recoveries were 91.2%-108.6%. The biles of 30 cases with cholelithiasis cholecystolithiasis and 20 cases without gallstone were detected by HPLC. The results showed that the constitution of bile acids was different between patients with cholelithiasis cholecystolithiasis and patients without gallstone.

Effect of gum chewing on ameliorating ileus following colorectal surgery: A meta-analysis of 18 randomized controlled trials.

Chewing gum, as an alternative to sham feeding, had been shown to hasten the recovery of gut function following abdominal surgery. However, conclusions remained contradictory. We sought to conduct an updated meta-analysis to evaluate the efficacy of gum chewing in alleviating ileus following colorectal surgery. We searched PubMed, EMBASE, and Cochrane Library Databases through February 2017 to identify randomized controlled trials (RCTs) evaluating the efficacy of the additional use of chewing gum following colorectal surgery. After screening for inclusion, data extraction, and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software. The outcomes of interest were the time to first flatus, time to first bowel movement, length of hospital stay, and some clinically relevant parameters. We also performed subgroup analyses according to the type of surgical approaches or on trials that adopted enhanced recovery after surgery (ERAS) protocol or sugared gum. A total of 18 RCTs, involving 1736 patients, were included. Compared with standardized postoperative care, Chewing gum resulted in a shorter passage to first flatus [WMD = -8.81, 95%CI: (-13.45, -4.17), P = 0.0002], earlier recovery of bowel movement [WMD = -16.43, 95%CI: (-22.68, -10.19), P < 0.00001], and a reduction in length of hospital stay [WMD = -0.89, 95%CI: (-1.72, -0.07), P = 0.03]. Chewing gum was also associated with a lower risk of postoperative ileus [OR = 0.41, 95%CI: (0.23, 0.73), P = 0.003]. No evidence of significant advantages in overall postoperative complication, nausea, vomiting, bloating, readmission and reoperation towards the addition of chewing gum was observed. Subgroup analyses all favored gum chewing. However, the findings are hampered by the significant heterogeneity between trials. Based on current evidence, chewing gum offers an inexpensive, well-tolerated, safe and effective method to ameliorate ileus following colorectal surgery. However, tightly controlled, randomized and considerably larger multicenter trials are warranted to further validate our findings. Copyright © 2017. Published by Elsevier Ltd.

Involvement of Cannabinoid Signaling in Vincristine-Induced Gastrointestinal Dysmotility in the Rat.

Background: In different models of paralytic ileus, cannabinoid receptors are overexpressed and endogenous cannabinoids are massively released, contributing to gastrointestinal dysmotility. The antitumoral drug vincristine depresses gastrointestinal motility and a similar mechanism could participate in this effect. Therefore, our aim was to determine, using CB 1 and CB 2 antagonists, whether an increased endocannabinoid tone is involved in vincristine-induced gastrointestinal ileus. Methods: First, we confirmed the effects of vincristine on the gut mucosa, by conventional histological techniques, and characterized its effects on motility, by radiographic means. Conscious male Wistar rats received an intraperitoneal injection of vincristine (0.1-0.5 mg/kg), and barium sulfate (2.5 ml; 2 g/ml) was intragastrically administered 0, 24, or 48 h later. Serial X-rays were obtained at different time-points (0-8 h) after contrast. X-rays were used to build motility curves for each gastrointestinal region and determine the size of stomach and caecum. Tissue samples were taken for histology 48 h after saline or vincristine (0.5 mg/kg). Second, AM251 (a CB 1 receptor antagonist) and AM630 (a CB 2 receptor antagonist) were used to determine if CB 1 and/or CB 2 receptors are involved in vincristine-induced gastrointestinal dysmotility. Key results: Vincristine induced damage to the mucosa of ileum and colon and reduced gastrointestinal motor function at 0.5 mg/kg. The effect on motor function was particularly evident when the study started 24 h after administration. AM251, but not AM630, significantly prevented vincristine effect, particularly in the small intestine, when administered thrice. AM251 alone did not significantly alter gastrointestinal motility. Conclusions: The fact that AM251, but not AM630, is capable of reducing the effect of vincristine suggests that, like in other experimental models of paralytic ileus, an increased cannabinoid tone develops and is at least partially responsible for the alterations induced by the antitumoral drug on gastrointestinal motor function. Thus, CB 1 antagonists might be useful to prevent/treat ileus induced by vincristine.

Si, Gu Leng Ri; Yao, Peng; Shi, Luwen

2015-08-01

A valid and efficient reversed-phase ultra-fast liquid chromatography method was developed for the simultaneous determination of 13 bile acids in the bile of three mammal species, including rat, pig and human gallstone patients. Chromatographic separation was performed with a Shim-pack XR-ODS column, and the mobile phase consisted of acetonitrile and potassium phosphate buffer (pH 2.6) at a flow rate of 0.5 mL min(-1). The linear detection range of most bile acids ranged from 2 to 600 ng µL(-1) with a good correlation coefficient (>0.9995). The precision of each bile acid was <1.8% for intraday and <4.8% for interday. All bile acids were separated in 15 min with satisfactory resolution, and the total analysis time was 18 min, including equilibration. The method was successfully applied in rapid screening of bile samples from the three mammals. Significant metabolic frameworks of bile acids among various species were observed, whereas considerable quantitative variations in both inter- and intraspecies were also observed, especially for gallstone patients. Our results suggest that detecting the change of bile acid profiles could be applied for the diagnosis of gallstone disease. © Crown copyright 2014.

Biliary Polyunsaturated Fatty Acids and Telocytes in Gallstone Disease

It has been reported that intake of ω-3 polyunsaturated fatty acids (PUFAs) reduces the risk of coronary heart disease. It also influences bile composition, decreasing biliary cholesterol saturation in the bile of patients with gallstones. In addition to bile composition disturbances, gallbladder hypomotility must be a cofactor in the pathogenesis of cholelithiasis, as it leads to the prolonged nucleation phase. Our current knowledge about gallbladder motility has been enhanced by the study of a population of newly described interstitial (stromal) cells—telocytes (TCs). The purpose of this study was to determine whether TC loss, reported by our team recently, might be related to bile lithogenicity, expressed as cholesterol saturation index or the difference in biliary PUFA profiles in patients who suffer from cholecystolithiasis and those not affected by this disease. We determined biliary lipid composition including the fatty acid composition of the phospholipid species in bile. Thus, we investigated whether differences in biliary fatty acid profiles (ω-3 PUFA and ω-6 PUFA) in gallbladder bile may influence its lithogenicity and the quantity of TCs within the gallbladder wall. We conclude that the altered PUFA concentrations in the gallbladder bile, with elevation of ω-6 PUFA, constitute important factors influencing TC density in the gallbladder wall, being one of the possible pathophysiological components for the gallstone disease development. This study established that altered bile composition in patients with cholelithiasis may influence TC quantity within the gallbladder muscle, and we concluded that reduction in TC number may be a consequence of the supersaturated bile toxicity, while some other bile components (ω-3 PUFA, glycocholic, and taurocholic acids) may exert protective effects on TC and thus possibly influence the mechanisms regulating gallbladder and extrahepatic bile duct motility. Thus, ω-3 PUFA may represent a possible option to prevent formation of cholesterol gallstones. PMID:27502173

This study compared serotonin concentrations in platelet poor plasma (PPP) from healthy horses and horses with surgical small intestinal (SI) colic, and evaluated their association with postoperative ileus, strangulation and non-survival. Plasma samples (with EDTA) from 33 horses with surgical SI colic were collected at several pre- and post-operative time points. Serotonin concentrations were determined using liquid-chromatography tandem mass spectrometry. Results were compared with those for 24 healthy control animals. The serotonin concentrations in PPP were significantly lower (P < 0.01) in pre- and post-operative samples from surgical SI colic horses compared to controls. However, no association with postoperative ileus or non-survival could be demonstrated at any time point. In this clinical study, plasma serotonin was not a suitable prognostic factor in horses with SI surgical colic. PMID:25694668

Epidural anaesthesia and analgesia - effects on surgical stress responses and implications for postoperative nutrition.

PubMed

Holte, K; Kehlet, H

2002-06-01

Surgical injury leads to an endocrine-metabolic and inflammatory response with protein catabolism, increased cardiovascular demands, impaired pulmonary function and paralytic ileus, the most important release mechanisms being afferent neural stimuli and inflammatory mediators. Epidural local anaesthetic blockade of afferent stimuli reduces endocrine metabolic responses, and improve postoperative catabolism. Furthermore, dynamic pain relief is achieved with improved pulmonary function and a pronounced reduction of postoperative ileus, thereby providing optimal conditions for improved mobilization and oral nutrition, and preservation of body composition and muscle function. Studies integrating continuous epidural local anaesthetics with enforced early nutrition and mobilization uniformly suggest an improved recovery, decreased hospital stay and convalescence. Epidural local anaesthetics should be included in a multi-modal rehabilitation programme after major surgical procedures in order to facilitate oral nutrition, improve recovery and reduce morbidity.

The efficacy of gum chewing in reducing postoperative ileus: a multisite randomized controlled trial.

2014-01-01

The purpose of this prospective, attention-controlled, randomized study was to determine whether postoperative gum chewing reduces the duration of postoperative ileus symptoms following elective open or laparoscopic sigmoid colectomy when compared with standard care or an attention-control intervention. Forty-seven subjects scheduled for either an open or laparoscopic colon resection participated in the study. Subjects were recruited preoperatively at the preadmission learning centers of the 2 acute care medical centers that comprised the study settings. Subjects were randomized to 3 groups: (1) standard postoperative care (n = 18); (2) standard care and a silicone-adhesive patch applied to the deltoid region of the upper arm as an attention control (n = 16); and (3) standard care and gum chewing (n = 13). Standard postoperative care included removal of the nasogastric tube, early ambulation, nothing by mouth with ice chips only until the first passage of flatus, and then advancement of diet until tolerance of solid food. No statistically significant differences were found among the 3 study groups for the 4 postoperative outcome variables measured: (1) first passage of flatus; (2) first bowel movement; (3) return of hunger; and (4) ability to tolerate solid food for one meal. Postoperative gum chewing was not found to be more effective than standard postoperative care or our attention-control intervention in reducing the duration of postoperative ileus symptoms, length of stay, or complications among patients following open/laparoscopic sigmoid colectomy.

To evaluate whether changes in gastric myoelectrical activity in healthy, awake dogs can be detected via multichannel electrogastrography (EGG). 6 healthy hound-breed dogs. For each dog, 8-channel EGG was performed after food had been withheld for 12 hours and at 30 minutes after subsequent feeding; 60 minutes after feeding, atropine (0.04 mg/kg) was administered IM to induce ileus, and 30 minutes later, EGG was again performed. Mean cycles per minute (cpm) values of the dominant frequency (a measure of the rhythmicity of gastric electrical activity) and mean power ratios (ie, power measured after treatment divided by the power measured when food was withheld) were calculated. Motility of the gastric antrum was assessed via B-mode ultrasonography during the same phases; contractions determined ultrasonographically were correlated with EGG power for each channel in each phase. The criterion for stability (SD of the dominant frequency < 15% of the cpm value in at least 3 of the 8 EGG channels) was met in 4 of the 6 dogs (only in long-distance channels). The mean power ratios were significantly higher in the postprandial phase than in the ileus phase. Compared with the postprandial phase, significantly fewer contractions per minute were evident ultrasonographically in the ileus and food-withholding phases. There was a significant and good correlation between EGG power and ultrasonographic findings in all 8 channels. Electrogastrography may be useful in assessing gastric myoelectrical activities in awake dogs with naturally occurring gastrointestinal disease, including gastric dilatation-volvulus.

Thirty-day unplanned hospital readmission in ovarian cancer patients undergoing primary or interval cytoreductive surgery: systematic literature review.

PubMed

Clark, Rachel M; Rice, Laurel W; Del Carmen, Marcela G

2018-06-18

Thirty-day readmission rate has been proposed as metric of quality and remains an ongoing clinical concern in the primary treatment of patients with advanced-stage ovarian epithelial ovarian cancer. We conducted a review of the literature to identify rates, risk factors, and predictors for 30-day readmission in this population. A 10-year period MEDLINE (PubMed) search of English literature studies published between January 01, 2008-January 01, 2018 was performed to identify appropriate studies for review. Thirty -day readmission rates for ovarian cancer patients undergoing primary treatment ranged from 2.5-19.3%. Neoadjuvant chemotherapy and interval cytoreductive surgery (NACT-ICS) surgery was associated with lower readmission rates, when compared to primary debulking surgery (PDS). The most frequently reported adverse events resulting in readmission include inpatient management of ileus/small bowel obstruction, wound-related complications, and thromboembolic events. Readmission predictors included the presence of other medical comorbidities, re-operation, and major complications occurring after initial hospital discharge. Some studies reported lower rates of readmission and survival in patients treated by NACT-ICS. Policies and programs should be designed to measure short- and long-term outcomes in this patient population to avoid bias in assigning patients to NACT-ICS to maintain low 30-day readmission rates.

2014-12-01

Demonstrate and report initial results using a carbon dioxide (CO2) laser for detrusor tunnel creation in robot-assisted laparoscopic extravesical ureteral reimplant (RALUR). Retrospective chart review was performed for cases of RALUR from 2011 to 2014. Patients undergoing complex reconstruction (ureteral tailoring, dismembered reimplant, concomitant ureteroureterostomy), and those who had incomplete follow-up were excluded. Variables, including use of the CO2 laser, were collected and correlated with outcomes. 23 patients representing 40 ureteral units were included for analysis. A CO2 laser was used in 9/23 (39%) patients and 16/40 (40%) ureteral units. Intraoperative mucosotomy was reported in 3/14 (21%) patients for the electrocautery group and 1/9 (11%) patients for the CO2 laser group. Resolution of VUR was observed in 11/14 (79%), and 9/9 (100%) of patients for the electrocautery group and the CO2 laser group, respectively. Two complications were identified in the electrocautery group of patients: ileus (Clavien 2), and transient bilateral ureteral obstruction requiring placement of ureteral stents (Clavien 3B). There were no complications in the CO2 laser group. Creation of the detrusor tunnel with a CO2 laser is safe and effective, and is associated with a lower rate of failure and complication in this cohort.

2018-01-01

Women with endometriosis often experience pain and infertility. Medical treatment interferes with the possibility of attaining pregnancy. For infertile women with endometriosis, surgery is a possible treatment, but with advanced disease there is an increased risk of serious complications. With only limited pain, women will often be referred for in vitro fertilization treatment instead. The disease is estrogen-dependent and during in vitro fertilization treatment the women could theoretically experience worsening of their symptoms. The study is a retrospective cohort study of 76 women with bowel endometriosis who were treated conservatively and underwent in vitro fertilization treatment. Nine (11.8%) of the women experienced severe worsening of their bowel-related symptoms, including two patients presenting with colon ileus. One additional woman had no previous diagnosis of endometriosis before she presented with subocclusion of the bowel during in vitro fertilization. In all cases the in vitro fertilization treatment was stopped. Our study revealed that bowel endometriosis increases the risk of complications during in vitro fertilization treatment. This is in contrast to several publications. However, our study population is different due to the fact that none of these women had previous operations for bowel endometriosis. In all, 88% of the women completed fertility treatment without need for surgery. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Trypsin level in gallbladder bile and ductitis and width of the cystic duct.

PubMed

Vracko, J; Wiechel, K L

2000-01-01

The change from laparotomy to laparoscopy for cholecystectomy has raised the question of how to manage concomitant bile duct stones. The present-day interest--and controversy--has focused on a transcystic approach reported to be feasible in 66-96% of cases, but without explaining the necessary prerequisite: the widening of the cystic duct. The cystic duct, wide mainly in patients with bile duct stones, has been reported to be highly variable: from strictured to very wide. The present study aims at comparing the trypsin level in the gallbladder bile and the cystic duct morphology and width in patients with and without bile duct stones. A prospective series of 63 gallstone patients, 30 with and 33 without bile duct stones (controls), underwent cholecystectomy and bile duct clearance. The study includes the trypsin level in the gallbladder bile, the width and morphology of the cystic duct, and the size of the gallstones. The patients with bile duct stones had, in contrast to the controls, higher trypsin levels in the gallbladder bile (P < 0.001) and wider cystic ducts (P < 0.001) with more pronounced signs of chronic ductitis. The obtained results strongly suggest that the increased trypsin level, a sign of reflux of pancreatic juice, caused changes in the cystic duct that facilitate gallstone migration, which also ought to render a transcystic stone extraction feasible.

Chemical composition of gall stones is essential for aetiopathogensis of gallstone disease. We have reported quantitative chemical analysis of total cholesterol bilirubin, calcium, iron and inorganic phosphate in 120 gallstones from haryana. To extend this chemical analysis of gall stones by studying more cases and by analyzing more chemical constituents. A quantitative chemical analysis of total cholesterol, total bilirubin, fatty acids, triglycerides, phospholipids, bile acids, soluble proteins, sodium potassium, magnesium, copper, oxalate and chlorides of biliary calculi (52 cholesterol, 76 mixed and 72 pigment) retrieved from surgical operation of 200 patients from Haryana state was carried out. Total cholesterol as the major component and total bilirubin, phospholipids, triglycerides, bile acids, fatty acids (esterified), soluble protein, calcium, magnesium, iron, copper, sodium, potassium, inorganic phosphate, oxalate and chloride as minor components were found in all types of calculi. The cholesterol stones had higher content of total cholesterol, phospholipids, fatty acids (esterified), inorganic phosphate and copper compared to mixed and pigment stones. The mixed stones had higher content of iron and triglycerides than to cholesterol and pigment stones. The pigment stones were richer in total bilirubin, bile acids, calcium, oxalate, magnesium, sodium, potassium, chloride and soluble protein compared to cholesterol and mixed stones. Although total cholesterol was a major component of cholesterol, mixed and pigment gall stone in Haryana, the content of most of the other lipids, cations and anions was different in different gall stones indicating their different mechanism of formation.

Hereditary spherocytosis is a clinically heterogeneous, genetically determined red blood cell membrane disorder resulting in hemolytic anemia. A deficiency of spectrin, the largest and most abundant structural protein of the erythrocyte membrane skeleton, results in the formation of spherocytes which lack the strength, durability, and flexibility to withstand the stresses of the circulation. Clinical manifestations of the disease are primarily dependent on the severity of hemolysis, which additionally results in an increased incidence of pigment gallstones. The likelihood of cholelithiasis is directly related to patient age and is uncommon before 10 years of age. Splenectomy is indicated in virtually every patient. When the disease is diagnosed in early childhood, the risk of overwhelming postsplenectomy sepsis makes it advisable to delay splenectomy until after 6 years of age if possible. At the time of splenectomy, it is important to identify and remove any accessory spleens. If gallstones are present, cholecystectomy should be performed. Although spherocytosis persists following splenectomy, hemolysis is alleviated and clinical cure of the anemia is achieved for most patients. Patients with recessively inherited spherocytosis are exceptions. Although they are significantly benefited by splenectomy, their anemia is not completely corrected. Splenectomy reduces hemolysis in all patients and thereby decreases the risk for development of pigment gallstones. Excision of an enlarged spleen removes the danger of traumatic rupture.

Acute pancreatitis in pregnancy is a rare and dangerous disease. This study aimed to examine the etiology, treatment, and outcomes of pancreatitis in pregnancy. A total of 25 pregnant patients diagnosed with pancreatitis during the period of 1994 and 2014 was analyzed retrospectively. The pregnant patients were diagnosed with pancreatitis during a period of 21 years. Most (60%) of the patients were diagnosed with pancreatitis in the third trimester. The mean age of the patients at presentation was 25.7 years, with a mean gestational age of 24.4 weeks. Abdominal pain occurred in most patients and vomiting in one patient was associated hyperemesis gravidarum. The common cause of the disease was gallstone-related (56%), followed by alcohol-related (16%), post-ERCP (4%), hereditary (4%) and undetermined conditions (20%). The level of triglycerides was minimally high in three patients. ERCP and wire-guided sphincterotomy were performed in 6 (43%) of 14 patients with gallstone-related pancreatitis and elevated liver enzymes with no complications. Most (84%) of the patients underwent a full-term, vaginal delivery. There was no difference in either maternal or fetal outcomes after ERCP. Acute pancreatitis is rare in pregnancy, occurring most commonly in the third trimester, and gallstones are the most common cause. When laparoscopic cholecystectomy is not feasible and a common bile duct stone is highly suspected on imaging, endoscopic sphincterotomy or stenting may help to prevent recurrence and postpone cholecystectomy until after delivery.

Surgical handling of the bowel evokes degranulation of peritoneal mast cells (PMC). Nonetheless, role of PMCs in postoperative ileus (POI) is somewhat controversial. We aimed to investigate if intestinal manipulation elicits changes in afferent mediators related to MC activation and alteration of gastrointestinal (GI) motility. Postoperative ileus was induced by intestinal manipulation in Sprague-Dawley rats. Additionally, compound 48/80 (C48/80) and ketotifen were used to modulate MC activity. Rat mast cell protease 6 (RMCP-6, ELISA) release was determined in peritoneal lavage 20 min after intestinal manipulation. At 24 h, GI transit was determined. Gene expression of calcitonin gene-related peptide (CGRP), protease-activated receptor-2 (PAR-2), nerve growth factor (NGF), and TrkA receptor was determined (PCR) in dorsal root ganglia (DRG). Ileal wall inflammation was assessed by myeloperoxidase (MPO) activity, interleukin-6 expression (IL-6). Intestinal manipulation and exposure to C48/80-induced degranulation of PMCs delayed GI transit and up-regulated IL-6 and MPO activity. Intestinal manipulation, but not C48/80, up-regulated CGRP, PAR-2, and NGF/TrkA in DRGs. Ketotifen only improved gastric emptying and fecal output. Up-regulation of CGRP and TrkA expression in DRG was not prevented by ketotifen. Postoperative ileus is accompanied by activation of CGRP, NGF-TrkA, and PAR-2 in DRGs. Our results suggest that these mediators could be a target in further POI studies in order to find new therapeutic targets for this medical condition. © 2016 John Wiley & Sons Ltd.

Paralytic postoperative ileus (POI) is associated with increased morbidity and mortality after abdominal surgery. Despite increased awareness and implementation of various measures, POI remains a problem, perhaps moreso for those patients undergoing extensive oncological surgical treatment. The aim of this study was to describe the extent of POI after advanced cancer surgery in the era of contemporary treatment modalities of POI. A retrospective analysis of all patients who underwent either abdominoperineal excision with transpelvic vertical rectus abdominal musculocutaneous (VRAM)-flap after anal cancer or pelvic exenteration at single institution from January 2012 to November 2013 was carried out. Patients were identified from operative codes, and data were retrieved from patient records. Eighty-nine patients were included in the study, 21 abdominoperineal excision and 68 pelvic exenteration procedures. Median nasogastric tube duration was 4 days (range: 0-44). Median time to first flatus was 1 day (range 0-15). Median time to defecation was 3 days (range 0-16 days). Twenty-three patients (28%) experienced prolonged ileus. There was a significant longer time to first defecation for patients who received a VRAM flap (P = 0.046). There was also a significant association between longer operative times and first flatus (P = 0.007). This retrospective study reveals that POI remains as a significant clinical problem in patients undergoing advanced pelvic cancer surgery, despite the increased awareness and implementation of enhanced recovery protocols. New regimens for better prophylaxis are needed, and further research on POI treatment is important. Copyright © 2017 Elsevier Inc. All rights reserved.

Acute pancreatitis is rare in pregnancy but it is associated with increased incidence of maternal and fetal mortality. It should be considered in the differential diagnosis of upper quadrant abdominal pain with or without nausea and vomiting. The commonest identified causes of acute pancreatitis in pregnancy are gallstones, alcohol and hypertriglyceridemia. The main laboratory finding is increased amylase activity. Appropriate investigations include ultrasound of the right upper quadrant and measurement of serum triglycerides and ionized calcium. Management of gallstone pancreatitis is controversial, although laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) are often used and may be associated with lower complication rates. In hypertriglyceridemia-induced acute pancreatitis ω-3 fatty acids and even therapeutic plasma exchange can be used. We also discuss preventive measures. Copyright © 2011 Elsevier Ireland Ltd.

Clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones or cholecystitis: a systematic review and economic evaluation.

Approximately 10-15% of the adult population suffer from gallstone disease, cholelithiasis, with more women than men being affected. Cholecystectomy is the treatment of choice for people who present with biliary pain or acute cholecystitis and evidence of gallstones. However, some people do not experience a recurrence after an initial episode of biliary pain or cholecystitis. As most of the current research focuses on the surgical management of the disease, less attention has been dedicated to the consequences of conservative management. To determine the clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management in people presenting with uncomplicated symptomatic gallstones (biliary pain) or cholecystitis. We searched all major electronic databases (e.g. MEDLINE, EMBASE, Science Citation Index, Bioscience Information Service, Cochrane Central Register of Controlled Trials) from 1980 to September 2012 and we contacted experts in the field. Evidence was considered from randomised controlled trials (RCTs) and non-randomised comparative studies that enrolled people with symptomatic gallstone disease (pain attacks only and/or acute cholecystitis). Two reviewers independently extracted data and assessed the risk of bias of included studies. Standard meta-analysis techniques were used to combine results from included studies. A de novo Markov model was developed to assess the cost-effectiveness of the interventions. Two Norwegian RCTs involving 201 participants were included. Eighty-eight per cent of people randomised to surgery and 45% of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications [risk ratio = 6.69; 95% confidence interval (CI) 1.57 to 28.51; p = 0.01], in particular acute cholecystitis (risk ratio = 9.55; 95% CI 1.25 to 73.27; p = 0.03), and less likely to undergo surgery (risk ratio = 0.50; 95% CI 0.34 to 0.73; p = 0.0004), experience surgery-related complications (risk ratio = 0.36; 95% CI 0.16 to 0.81; p = 0.01) or, more specifically, minor surgery-related complications (risk ratio = 0.11; 95% CI 0.02 to 0.56; p = 0.008) than those randomised to surgery. Fifty-five per cent of people randomised to observation did not require an operation during the 14-year follow-up period and 12% of people randomised to cholecystectomy did not undergo the scheduled operation. The results of the economic evaluation suggest that, on average, the surgery strategy costs £1236 more per patient than the conservative management strategy but was, on average, more effective. An increase in the number of people requiring surgery while treated conservatively corresponded to a reduction in the cost-effectiveness of the conservative strategy. There was uncertainty around some of the parameters used in the economic model. The results of this assessment indicate that cholecystectomy is still the treatment of choice for many symptomatic people. However, approximately half of the people in the observation group did not require surgery or suffer complications in the long term indicating that a conservative therapeutic approach may represent a valid alternative to surgery in this group of people. Owing to the dearth of current evidence in the UK setting a large, well-designed, multicentre trial is needed. The study was registered as PROSPERO CRD42012002817.

Laparoscopic completion cholecystectomy and common bile duct exploration for retained gallbladder after single-incision cholecystectomy.

PubMed

Kroh, Matthew; Chalikonda, Sricharan; Chand, Bipan; Walsh, R Matthew

Recent enthusiasm in the surgical community for less invasive surgical approaches has resulted in widespread application of single-incision techniques. This has been most commonly applied in laparoscopic cholecystectomy in general surgery. Cosmesis appears to be improved, but other advantages remain to be seen. Feasibility has been demonstrated, but there is little description in the current literature regarding complications. We report the case of a patient who previously underwent single-incision laparoscopic cholecystectomy for symptomatic gallstone disease. After a brief symptom-free interval, she developed acute pancreatitis. At evaluation, imaging results of ultrasonography and magnetic resonance cholangiopancreatography demonstrated a retained gallbladder with cholelithiasis. The patient was subsequently referred to our hospital, where she underwent further evaluation and surgical intervention. Our patient underwent 4-port laparoscopic remnant cholecystectomy with transcystic common bile duct exploration. Operative exploration demonstrated a large remnant gallbladder and a partially obstructed cystic duct with many stones. Transcystic exploration with balloon extraction resulted in duct clearance. The procedure took 75 minutes, with minimal blood loss. The patient's postoperative course was uneventful. Final pathology results demonstrated a remnant gallbladder with cholelithiasis and cholecystitis. This report is the first in the literature to describe successful laparoscopic remnant cholecystectomy and transcystic common bile duct exploration after previous single-port cholecystectomy. Although inadvertent partial cholecystectomy is not unique to this technique, single-port laparoscopic procedures may result in different and significant complications.

Persistent Salmonellosis Causes Pancreatitis in a Murine Model of Infection

Pancreatitis, a known risk factor for the development of pancreatic ductal adenocarcinoma, is a serious, widespread medical condition usually caused by alcohol abuse or gallstone-mediated ductal obstruction. However, many cases of pancreatitis are of an unknown etiology. Pancreatitis has been linked to bacterial infection, but causality has yet to be established. Here, we found that persistent infection of mice with the bacterial pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) was sufficient to induce pancreatitis reminiscent of the human disease. Specifically, we found that pancreatitis induced by persistent S. Typhimurium infection was characterized by a loss of pancreatic acinar cells, acinar-to-ductal metaplasia, fibrosis and accumulation of inflammatory cells, including CD11b+ F4/80+, CD11b+ Ly6Cint Ly6G+ and CD11b+ Ly6Chi Ly6G− cells. Furthermore, we found that S. Typhimurium colonized and persisted in the pancreas, associated with pancreatic acinar cells in vivo, and could invade cultured pancreatic acinar cells in vitro. Thus, persistent infection of mice with S. Typhimurium may serve as a useful model for the study of pancreatitis as it relates to bacterial infection. Increased knowledge of how pathogenic bacteria can cause pancreatitis will provide a more integrated picture of the etiology of the disease and could lead to the development of new therapeutic approaches for treatment and prevention of pancreatitis and pancreatic ductal adenocarcinoma.

Abdominal emergencies during pregnancy.

Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

Owing to several therapeutic advancements, more patients with biliary atresia now survive into adulthood while retaining their native liver. However, the optimal strategy for long-term management of such patients remains unclear. Aiming to establish the current management strategies, we reviewed previous reports of long-term outcome of BA who underwent surgery at our institution as well as the relevant literature, focusing particularly on the treatment of late complications. Approximately 30-40% of long-term survivors of biliary atresia who retain their native liver exhibit late sequelae such as cholangitis and portal hypertension. Early and appropriate intervention with Kasai portoenterostomy is essential for ensuring long-term survival with good quality of life. In our hospital, the current standard for Kasai portoenterostomy involves dissecting the fibrous remnants along the porta hepatis, just on the level of the liver capsule. Cholangitis is an important late complication in biliary atresia, and the possibility of mechanical obstruction of the biliary drainage route or deformity of the intrahepatic bile ducts with or without gallstones should be thoroughly evaluated in patients with intractable cholangitis. Regarding portal hypertension, appropriate interventions such as endoscopic variceal treatment and partial splenic embolization are considered to provide good quality of life when hepatic function is preserved. Appropriate therapeutic management is strongly recommended in selected patients with late complications.

Extraction of a gallbladder through an endoscopic overtube during natural orifice translumenal endoscopic surgery (NOTES) transgastric cholecystectomy avoids potential injury to the esophagus. This study examined the rate of successful gallbladder specimen extraction through an overtube and hypothesized that preoperative ultrasound findings could predict successful specimen passage. Gallbladder specimens from patients undergoing laparoscopic cholecystectomy were measured, and an attempt was made to pull the specimens through a commercially available overtube with an inner diameter of 16.7-mm. A radiologist blinded to the outcomes reviewed the available preoperative ultrasound measurements from these patients. Ultrasound dimensions including gallbladder length, width, and depth; wall thickness; common bile duct diameter; and size of the largest gallstone (LGS) were recorded. Multiple logistic regression analysis was performed to determine whether ultrasound findings and patient characteristics (age, body mass index [BMI], and sex) could predict the ability of a specimen to pass through the overtube. Of 57 patients, 44 (77%) who had preoperative ultrasounds available for electronic review were included in the final analysis. Gallstones were present in 35 (79%) of these 44 patients. Intraoperative gallbladder perforation occurred in 18 (41%) of the 44 patients, and 16 (36%) of the 44 gallbladders could be extracted through the overtube. Measurement of LGS was possible for 23 patients, and indeterminate gallstone size (IGS) was determined for 12 patients. The rate for passage of perforated versus intact gallbladders was similar (40% vs. 23%; p = 0.054). The LGS (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.02-1.33; p = 0.021) and IGS (OR, 22.97; 95% CI, 1.99-265.63; p = 0.025) predicted failed passage on multivariate logistic regression analysis. The passage rate was 80% for LGS smaller than 10 mm or no stones present, 18% for LGS 10 mm or larger, and 8% for IGS (p < 0.001). A majority of cholecystectomy specimens cannot pass through an endoscopic overtube. Preoperative ultrasound findings can predict successful specimen extraction. An IGS or a gallstone 10 mm or larger should be considered a relative contraindication to transgastric NOTES cholecystectomy.

The organic matrix of gallstones

Dissolution of gallstones consisting of cholesterol, calcium carbonate, or calcium phosphate in different solvents left an amorphous organic gel-like substance (the matrix). Matrix from cholesterol stones could be colourless but was usually orange, yellow, or brown while that from calcium carbonate and calcium phosphate stones was almost invariably coloured black or dark brown. These pigments were also shown to be organic and amorphous. The amount of matrix present and its structure varied with the texture of the crystalline material. Irrespective of their composition, laminated pieces of material yielded compact laminated matrix of the same shape as the original piece and areas of loose crystalline material gave small pieces of non-cohesive matrix. Only large cholesterol crystals which usually radiate from the stone nucleus had no associated matrix. ImagesFig 1Fig 2Fig 3Fig 4Fig 5 PMID:4854981

To determine whether an endoscopic sphincterotomy affects outcome in patients with symptomatic gallstones, elevated liver function tests and a normal common bile duct on endoscopic retrograde cholangiopancreatogram. A total of 163 patients with symptomatic gallstones and elevated liver function tests, and found to have a normal common bile duct on endoscopic retrograde cholangiopancreatogram were included in the study. Endoscopic sphincterotomy was performed in 78 (47.8%) patients, while 85 (52.1%) patients did not have an endoscopic sphincterotomy. The two groups were compared for detection of small unseen common bile duct stones/debris, endoscopic retrograde cholangiopancreatogram related complications, and biliary complications after cholecystectomy. Small common bile duct stones/debris were recovered in 11/43 (25.5%) patients who had instrumentation of the common bile duct performed after endoscopic sphincterotomy. Common bile duct instrumentation was not performed in any of the patients without endoscopic sphincterotomy. No patient had any biliary complication after cholecystectomy, both in the immediate postoperative period and on a follow-up of 37.5 +/- 13.6 months (range 17-66). Endoscopic retrograde cholangiopancreatogram related complications occurred in 8 patients who had an endoscopic sphincterotomy and in 2 without endoscopic sphincterotomy (p < 0.05). Performing an endoscopic sphincterotomy in these patients increases the detection of small unseen common bile duct stones/debris without changing the clinical outcome after cholecystectomy. It also increases the endoscopic retrograde cholangiopancreatogram related complication rate, and therefore may not be necessary.

The major mechanisms of gallstone formation include biliary cholesterol hypersecretion, supersaturation and crystallization, mucus hypersecretion, gel formation and bile stasis. Gallbladder hypomotility seems to be a key event that triggers the precipitation of cholesterol microcrystals from supersaturated lithogenic bile. Telocytes, a new type of interstitial cells, have been recently identified in many organs, including gallbladder. Considering telocyte functions, it is presumed that these cells might be involved in the signalling processes. The purpose of this study was to correlate the quantity of telocytes in the gallbladder with the lithogenicity of bile. Gallbladder specimens were collected from 24 patients who underwent elective laparoscopic cholecystectomy for symptomatic gallstone disease. The control group consisted of 25 consecutive patients who received elective treatment for pancreatic head tumours. Telocytes were visualized in paraffin sections of gallbladders with double immunofluorescence using primary antibodies against c-Kit (anti-CD117) and anti-mast cell tryptase. Cholesterol, phospholipid and bile acid levels were measured in gallbladder bile. The number of telocytes in the gallbladder wall was significantly lower in the study group than that in the control group (3.03 ± 1.43 versus 6.34 ± 1.66 cell/field of view in the muscularis propria, P < 0.001) and correlated with a significant increase in the cholesterol saturation index. The glycocholic and taurocholic acid levels were significantly elevated in the control subjects compared with the study group. The results suggest that bile composition may play an important role in the reduction in telocytes density in the gallbladder. PMID:23551596

Gallbladder cancer worldwide: geographical distribution and risk factors.

Gallbladder cancer is a relatively rare neoplasm that shows, however, high incidence rates in certain world populations. The interplay of genetic susceptibility, lifestyle factors and infections in gallbladder carcinogenesis is still poorly understood. Age-adjusted rates were calculated by cancer registry-based data. Epidemiological studies on gallbladder cancer were selected through searches of literature, and relative risks were abstracted for major risk factors. The highest gallbladder cancer incidence rates worldwide were reported for women in Delhi, India (21.5/100,000), South Karachi, Pakistan (13.8/100,000) and Quito, Ecuador (12.9/100,000). High incidence was found in Korea and Japan and some central and eastern European countries. Female-to-male incidence ratios were generally around 3, but ranged from 1 in Far East Asia to over 5 in Spain and Colombia. History of gallstones was the strongest risk factor for gallbladder cancer, with a pooled relative risk (RR) of 4.9 [95% confidence interval (CI): 3.3-7.4]. Consistent associations were also present with obesity, multiparity and chronic infections like Salmonella typhi and S. paratyphi [pooled RR 4.8 (95% CI: 1.4-17.3)] and Helicobacter bilis and H. pylori [pooled RR 4.3 (95% CI: 2.1-8.8)]. Differences in incidence ratios point to variations in gallbladder cancer aetiology in different populations. Diagnosis of gallstones and removal of gallbladder currently represent the keystone to gallbladder cancer prevention, but interventions able to prevent obesity, cholecystitis and gallstone formation should be assessed.

Short-term outcome of total clipless laparoscopic cholecystectomy for complicated gallbladder stones in cirrhotic patients.

Cirrhotic patients have been known to be more affected with gallstones than their non-cirrhotic counterparts; since laparoscopy was introduced, it has been generally approved as the standard approach for cholecystectomies with the exception of end-stage cirrhosis. The purpose of this study was to evaluate the safety and efficacy of clipless laparoscopic cholecystectomy using the harmonic scalpel in complicated cholelithiasis in cirrhotic patients. This prospective study was conducted on 62 cirrhotic patients presenting to the Gastrointestinal Surgery Unit in Alexandria Main University Hospital with complicated gallstones between March 2013 and March 2016. Both intraoperative time and blood loss were calculated in addition to rates of conversion to open cholecystectomy, morbidity and mortality. Most of our cases were females with a ratio of 1.7:1, with a mean age of 45.21 years, ranging from 25 to 65 years. The most common cause of cirrhotic liver was hepatitis C in 45.1% of patients. Among the 62 patients included in the study, 56 patients (90.3%) were presenting with acute cholecystitis and six patients were operated at the onset of acute biliary pancreatitis. The mean operative time was 72.9 min with mean blood loss 45.45 mL. The study concluded safety of total clipless laparoscopic cholecystectomy using a harmonic scalpel in Child A and B type cirrhotic patients, who presented with complicated gallstones. © 2017 Royal Australasian College of Surgeons.

Postoperative ileus is a significant clinical challenge lacking effective management strategies. Ghrelin-receptor stimulation has promotility effects in the upper and lower gastrointestinal tract. This proof-of-concept, phase 2, randomized study evaluated the safety and efficacy of the ghrelin-receptor agonist ipamorelin in the treatment of postoperative ileus following abdominal surgery (ClinicalTrials.gov NCT00672074). The design was a multicenter, double-blind, placebo-controlled, clinical trial. The settings include hospital inpatients. The patients were adults undergoing small and large bowel resection by open or laparoscopic surgery. The intervention was intravenous infusions of 0.03-mg/kg ipamorelin vs placebo twice daily, on postoperative day 1 to 7 or hospital discharge. Safety was assessed by monitoring adverse events and laboratory tests. The key efficacy endpoint was time from first dose of study drug to tolerance of a standardized solid meal. One hundred seventeen patients were enrolled, of whom 114 patients composed the safety and modified intent-to-treat populations. Demographic and disease characteristics were balanced between groups. Overall incidence of any treatment-emergent adverse events was 87.5 % in the ipamorelin group and 94.8 % in placebo group. Median time to first tolerated meal was 25.3 and 32.6 h in the ipamorelin and placebo groups, respectively (p = 0.15). This proof of concept study was small and enrolled patients with a broad range of underlying conditions. Ipamorelin 0.03-mg/kg twice daily for up to 7 days was well tolerated. There were no significant differences between ipamorelin and placebo in the key and secondary efficacy analyses.

Postoperative ileus (POI) is a common complication after spine surgery, with particularly high rates after adult spinal deformity surgery (ASD). Few investigations have been conducted, however, on predictors of POI following ASD. The objective of this investigation was to determine risk factors for POI in patients undergoing ASD. We also sought to determine the association between POI and in-hospital mortality, length of stay, and total charges. Data were obtained from the National/Nationwide Inpatient Sample, years 2010 - 2014. ASD patients aged ≥26 years-old were selected using ICD-9-CM codes. Multiple logistic and linear regression were utilized. In total, 59,410 patients were included in the analysis. 7.4% of patients experienced POI. On adjusted analysis, the following variables were associated with increased risk of POI: male sex (OR 1.43, CI 1.10 - 1.85), anterior surgical approach (OR 1.78, CI 1.22 - 2.60), 9+ levels fused (OR 1.84, CI 1.24 - 2.73), electrolyte disorders (OR 2.70, CI 2.15 - 3.39), and pathologic weight loss (OR 1.94, CI 1.08 - 3.46). POI was associated with significantly longer length of stay (+39%, CI 29% - 51%) and higher total charges (+23%, CI 14% - 31%). Risk factors for POI were identified. Patients suffering from ileus exhibited 2.9 days longer length of stay and ∼$80,000 higher total charges. These results may be applied clinically to identify patients at risk of POI and to consider addressing modifiable risk factors preoperatively. Future studies should be conducted with additional data to develop models capable of accurately predicting and preventing POI. Copyright © 2018 Elsevier Inc. All rights reserved.

Postoperative ileus (POI) is a transient gastrointestinal (GI) dysmotility that commonly develops after abdominal surgery. YH12852, a novel, potent and highly selective 5-hydroxytryptamine 4 (5-HT 4 ) receptor agonist, has been shown to improve both upper and lower GI motility in various animal studies and may have applications for the treatment of POI. Here, we investigated the effects and mechanism of action of YH12852 in a guinea pig model of POI to explore its therapeutic potential. The guinea pig model of POI was created by laparotomy, evisceration, and gentle manipulation of the cecum for 60 seconds, followed by closure with sutures under anesthesia. Group 1 received an oral administration of vehicle or YH12852 (1, 3, 10 or 30 mg/kg) only, while POI Group 2 was intraperitoneally pretreated with vehicle or 5-HT 4 receptor antagonist GR113808 (10 mg/kg) prior to oral dosing of vehicle or YH12852 (3 or 10 mg/kg). Upper GI transit was evaluated by assessing the migration of a charcoal mixture in the small intestine, while lower GI transit was assessed via measurement of fecal pellet output (FPO). YH12852 significantly accelerated upper and lower GI transit at the doses of 3, 10, and 30 mg/kg and reached its maximal effect at 10 mg/kg. These effects were significantly blocked by pretreatment of GR113808 10 mg/kg. Oral administration of YH12852 significantly accelerates and restores delayed upper and lower GI transit in a guinea pig model of POI. This drug may serve as a useful candidate for the treatment of postoperative ileus. © 2017 John Wiley & Sons Ltd.

Diverticula of small intestine are rare. Jejunal diverticula can be single or multiple. Diverticula in the jejunum tend to be large and multiple. Clinically they may be asymptomatic or may give rise to symptoms like pain, flatulence and borborygmi, may produce malabsorption syndrome or may present in emergency with different acute pathologies like perforation, haemorrhage, obstruction, enterolith formation and inflammation. The Objective was to see the pattern of complications in jejunal diverticula presenting as a surgical emergency. This descriptive study was conducted at Surgical Units of the 3 tertiary care Hospitals of Peshawar, for 7 years from January 1, 2002 to December 31, 2008. Study included all patients presenting to and admitted in Surgical Unit, Hayatabad Medical Complex, Peshawar with complicated jejunal diverticula during the above mentioned period. Name, age, sex, other relevant data, history and examination findings and results of investigation were recorded. Uncomplicated jejuna diverticula were excluded from study. The operative findings and the type of complication were recorded. Ten patients were admitted during 7 years of study. Out of all patients 9 were male and 1 was female. Eight out of 10 patients presented with perforation of diverticula while 1 patient had severe inflammation of diverticulum causing pain, ileus and acute abdomen. One patient had acute pain due to adhesion formation. It is seen that complicated jejunal diverticulae are quite rare and the most common complication is perforation. Inflammation and adhesion are other complications with which jejunal diverticula presented during this study.

The creation of a diverting loop ileostomy is associated with the risk of readmission due to stoma-related complications. We hypothesized that the assessment of our institution-specific readmissions following ileostomy creation would help identifying at-risk groups which should be the focus of future preventative strategies. Patients who underwent loop ileostomy formation from 2009 to 2013 were reviewed. We evaluated readmissions within 30 days after discharge following loop ileostomy construction. Possible associations between readmission and demographic, disease-related and treatment-related factors were assessed using univariate and multivariate analyses. Out of 1267 patients undergoing loop ileostomy construction, 163 patients (12.9%) were readmitted. The main causes of readmissions were organ/space infections (43, 3.4%), small bowel obstruction/ileus (42, 3.3%) and dehydration (38, 3%). Independent factors associated with overall readmission were cardiovascular (OR = 2.0) and renal comorbidity (OR = 2.9), preoperative chemo/radiotherapy (OR = 4.0), laparoscopic approach (OR = 1.7) and longer operative time (OR = 1.2). Cancer diagnosis was associated with reduced readmission rates (OR = 0.2). Independent factors associated with readmission due to dehydration were chemo/radiotherapy (OR = 4.7) and laparoscopic approach (OR = 2.6). Dehydration associated with diverting ileostomy creation was relevant as an individual cause of readmission, but its overall incidence was relatively rare. Dedicated strategies to prevent dehydration should be directed to patients who received chemoradiotherapy and/or laparoscopic surgery.

Retention of the video capsule is the most significant complication associated with capsule endoscopy (CE). There are limited data on incidence, risk factors, and outcomes of capsule retention. We aimed to determine the incidence of capsule retention and to investigate the causes and clinical outcomes of capsule retention. Single tertiary referral medical center. All patients who underwent CE for suspected small bowel disease from June 2002 to March 2006. Retrospective case series. Capsule retention occurred in 1.4% of our patients (14/1000). Eleven patients failed to pass the capsule because of nonsteroidal anti-inflammatory drug (NSAID) enteropathy (diaphragm disease). One patient had capsule retention from an obstructing carcinoid tumor. Metastatic ovarian cancer with invasion of the ileum was the cause of retention in another patient. One patient who did not have surgical removal of the capsule because of loss of follow-up had retention caused by a small-bowel tumor suspicious for carcinoid tumor on CT enterography. All patients remained "asymptomatic" from the retained capsules. Thirteen patients underwent elective partial small-bowel resection and capsule removal. No deaths were associated with these surgeries. Eleven patients recovered promptly, whereas 2 patients had mild postoperative ileus. Retrospective study. Retention of the capsule endoscope appears to be infrequent. The most common cause is diaphragm disease resulting from NSAIDs in this study population. In most cases, capsule retention is asymptomatic, and it usually leads to surgical removal, which appears safe and also identifies and treats the underlying small-bowel condition.

Accelerated recovery programs are clinical pathways which outline the stages, and streamline the means, and techniques aiming toward the desired end a rapid return of the patient to his pre-operative physical and psychological status. Recovery from colo-rectal surgery may be slowed by the patient's general health, surgical stress, post-surgical pain, and post-operative ileus. Both surgeons and anesthesiologists participate throughout the peri-operative period in a clinical pathway aimed at minimizing these delaying factors. Key elements of this pathway include avoidance of pre-operative colonic cleansing, early enteral feeding, and effective post-operative pain management permitting early ambulation (usually via thoracic epidural anesthesia). Pre-operative information and motivation of the patient is also a key to the success of this accelerated recovery program. Studies of such programs have shown decreased duration of post-operative ileus and hospital stay without an increase in complications or re-admissions. The elements of the clinical pathway must be regularly re-evaluated and updated according to local experience and published data.

On the growth rate of gallstones in the human gallbladder

NASA Astrophysics Data System (ADS)

Nudelman, I.

1993-05-01

The growth rate of a single symmetrically oval shaped gallbladder stone weighing 10.8 g was recorded over a period of six years before surgery and removal. The length of the stone was measured by ultrasonography and the growth rate was found to be linear with time, with a value of 0.4 mm/year. A smaller stone growing in the wall of the gallbladder was detected only three years before removal and grew at a rate of ˜ 1.33 mm/year. The morphology and metallic ion chemical composition of the large stone and of a randomly selected small stone weighing about 1.1 g, extracted from another patient, were analyzed and compared. It was found that the large stone contained besides calcium also lead, whereas the small stone contained mainly calcium. It is possible that the lead causes a difference in mechanism between the growth of a single large and growth of multiple small gallstones.

The urolithiasis, with a high incidence nowadays, including formations caused by gallstone of uric acid, has a high correlation to our lifestyles and dietary habits. Through a clinic case, it is intended to review the main nursing actions that may occur with this pathology. To achieve this, the data collected on physical examination and nursing assessment on the model of Virginia Henderson, while the full care plan is developed. The results show the need to establish a standardized healthy education intervention, related to a low-pruine healthy diet for people that suffer this disease. The amount of complications and problems associated with recidivism of hospital accommodation because of the ignorance of gallstone cases increase the risk of reducing the quality of life of the patients.

Gastrointestinal Complications of Obesity

PubMed Central

Camilleri, Michael; Malhi, Harmeet; Acosta, Andres

2017-01-01

Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

Shock waves: a new physical principle in medicine.

Brendel, W

1986-01-01

Shock wave therapy of kidney- and gallstones, i.e. extracorporeal shock wave lithotripsy (ESWL), is a new, noninvasive technique to destroy concrements in the kidney, the gallbladder and in the ductus choledochus. This method was developed by the Dornier Company, Friedrichshafen, FRG, and tested in animal experiments at the Institute for Surgical Research of the University of Munich. In the meantime, kidney lithotripsy has gained world-wide acceptance. More than 60,000 patients suffering from urolithiasis have been treated successfully, what made surgical removal of their kidney stones obsolete. Gallstone lithotripsy is, however, still at the very beginning of clinical trial. Lithotripsy of gallbladder stones will have to be applied in combination with urso- or chenodesoxycholic acid in order to obtain complete dissolution of the fragments. Potential hazards to living tissues are briefly mentioned. Since the lung is particularly susceptible, shock waves must enter the body at an angle which ensures that lung tissue is not affected.

This paper introduces a new method to detect the taurine and glycine conjugates of five different bile acids (cholic acid, deoxycholic acid, chenodeoxycholic acid, ursodeoxycholic acid and lithocholic acid) in human bile. Advantages of this method are sufficient separation of compounds within a short period of time and a high rate of reproducibility. Using a mobile phase gradient of acetonitrile and water, modified with tetrabutylammonium hydrogen sulphate (0.0075 mol/l), we were able to maximize the differentiation between ursodeoxycholic acid and lithocholic acid, which is of primary interest during conservative gallstone dissolution therapy. Use of this gradient reduced analysis time to less than 0.5 h. Recovery rates for this modified method ranged from 94% to 100%, and reproducibility was 98%, sufficient for routine clinical applications.

Severe acute pancreatitis and pregnancy.

For most patients with pregnancy-associated pancreatitis there is little maternal survival threat and only occasionally are there foetal deaths. We describe 4 young women with pregnancy-associated severe acute pancreatitis who each had gallstones. Their ages were 17, 18, 20 and 24 years. Each was a tertiary referral to our unit in Glasgow and each pursued a life-threatening course with hospital stays ranging from 37 to 90 days. One patient required pancreatic necrosectomy for infected necrosis, another had percutaneous management of a pancreatic abscess and 2 had cystogastrostomy as treatment for pancreatic pseudocyst. All underwent early endoscopic sphincterotomy and later cholecystectomy. It is important to be aware that pregnancy-associated acute pancreatitis may be severe, posing a survival threat even in the youngest patients. Gallstones, as we reported almost 20 years ago, are the most common aetiological factor in such patients. Copyright (c) 2006 S. Karger AG, Basel and IAP.

2018-05-25

Acute cholecystitis is a common serious complication of gallstones. The reported mortality of acute cholecystitis is approximately 3%, but the rate increases with age or comorbidity of the patient. If appropriate treatment is delayed, complications can develop as a consequence with a grave prognosis. The current standard of care in acute cholecystitis is an early laparoscopic cholecystectomy with the appropriate administration of fluid, electrolyte, and antibiotics. On the other hand, the severity of the disease and patient's operational risk must be considered. In those with high operational risks, gall bladder drainage can be performed as an alternative. Currently percutaneous and endoscopic drainage are available and show clinical success in most cases. After recovering from acute cholecystitis, the patients who have undergone drainage should be considered for cholecystectomy as a definitive treatment. However, in elderly patients or patients with significant comorbidity, operational risks may still be high, making cholecystectomy inappropriate. In these patients, gallstone removal using the percutaneous tract or endoscopy may be considered.

Scanty data exist on the role of personal medical conditions, except for gallstones, and family history of cancer on the risk of biliary tract cancers (BTC). We analyzed this issue using data from two Italian case-control studies, including 159 cases of BTC and 795 matched hospital controls. Odds ratios (ORs) of BTC and corresponding 95% confidence intervals (CIs) were estimated using multiple logistic regression models. Gallstones were associated with a 2-fold excess risk of BTC (95% CI 1.24-3.45). No significant associations were observed with other conditions investigated, including diabetes (OR 1.15, 95% CI 0.63-2.11), hypertension (OR 0.65, 95% CI 0.39-1.11), hyperlipidemia (OR 0.61, 95% CI 0.31-1.21), allergy (OR 0.64, 95% CI 0.29-1.40), gastroduodenal ulcer (OR 0.52, 95% CI 0.24-1.12), hepatitis (OR 2.02, 95% CI 0.35-11.67), benign thyroid diseases (OR 1.16, 95% CI 0.56-2.40), hysterectomy (OR 1.19, 95% CI 0.53-2.68), unilateral oophorectomy (OR 1.75, 95% CI 0.44-6.93), and bilateral oophorectomy (OR 2.48, 95% CI 0.79-7.82). We found an excess risk of BTC in relation to family history of any cancer (OR 1.52, 95% CI 1.03-2.24) and family history of gallbladder cancer (OR 3.83, 95% CI 0.59-24.75). The present study confirms a strong association between BTC and history of gallstones, and provides further evidence of a positive association with family history of cancer.

Subphrenic and Pleural Abscess Due to Spilled Gallstones

Varker, Kimberly A.; Zaydfudim, Victor; McKee, Jason

2006-01-01

Background: A 70-year-old male approximately 3 years after laparoscopic cholecystectomy presented to his primary care physician with a 4-month history of generalized malaise. Methods: A workup included magnetic resonance imaging that revealed a perihepatic abscess. The patient underwent ultrasound-guided drainage, with the removal of 1400 mL of purulent fluid and placement of 2 drains. Computed tomographic scanning showed resolution, and he was discharged home on oral antibiotics. At 2-month follow-up, the patient was asymptomatic, denying any constitutional symptoms. However, abdominal computed tomographic scanning revealed recurrence of the abscess, which measured approximately 18x9x7.5 cm, with mass effect on the liver. The patient was placed on intravenous antibiotics and scheduled for operative drainage. The abdomen was entered with a right subcostal incision, and 900 mL of purulent fluid was drained. We also noted abscess erosion through the inferolateral aspect of the right diaphragm into the pleural space. The pleural abscess was loculated and isolated from the lung parenchyma. Palpation within the abscess cavity revealed 9 large gallstones. Following copious irrigation and debridement of necrotic tissue, 3 drains were placed and the incision was closed. Results: The patient had an uneventful recovery and was discharged home on postoperative day number 6. Follow-up imaging at 3 months demonstrated resolution of the collection. Conclusion: Spillage of gallstones is a complication of laparoscopic cholecystectomy, occurring in 6% to 16% of all cases. Retained stones rarely result in a problem, but when complications arise, aggressive surgical intervention is usually necessary. PMID:16709371

Bacteria entombed in the center of cholesterol gallstones induce fewer infectious manifestations than bacteria in the matrix of pigment stones.

The clinical significance of bacteria in the pigment centers of cholesterol stones is unknown. We compared the infectious manifestations and characteristics of bacteria from pigment stones and predominantly cholesterol stones. Three hundred forty patients were studied. Bile was cultured. Gallstones were cultured and examined with scanning electron microscopy. Level of bacterial immunoglobulin G (bile, serum), complement killing, and tumor necrosis factor-alpha production were determined. Twenty-three percent of cholesterol stones and 68% of pigment stones contained bacteria (P < 0.0001). Stone culture correlated with scanning electron microscopy results. Pigment stone bacteria were more often present in bile and blood. Cholesterol stone bacteria caused more severe infections (19%) than sterile stones (0%), but less than pigment stone bacteria (57%) (P < 0.0001). Serum and bile from patients with cholesterol stone bacteria had less bacterial-specific immunoglobulin G. Cholesterol stone bacteria produced more slime. Pigment stone bacteria were more often killed by a patient's serum. Tumor necrosis factor-alpha production of the groups was similar. Bacteria are readily cultured from cholesterol stones with pigment centers, allowing for analysis of their virulence factors. Bacteria sequestered in cholesterol stones cause infectious manifestations, but less than bacteria in pigment stones. Possibly because of their isolation, cholesterol stone bacteria were less often present in bile and blood, induced less immunoglobulin G, were less often killed by a patient's serum, and demonstrated fewer infectious manifestations than pigment stone bacteria. This is the first study to analyze the clinical relevance of bacteria within cholesterol gallstones.

Role of phospholipase A2 in cholesterol gallstone formation is associated with biliary phospholipid species selection at the site of hepatic excretion: indirect evidence.

Phospholipase A2 plays a role in cholesterol gallstone development by hydrolyzing bile phospholipids into lysolecithin and free fatty acids. Lysolecithin and polyunsaturated free fatty acids are known to stimulate the synthesis and/or secretion of gallbladder mucin via a prostanoid pathway, leading to enhancing cholesterol crystal nucleation and growth, and therefore, the action of phospholipase A2 is associated, in part, with bile phospholipid fatty acid. To clarify this hypothesis, we evaluated the effect on bile lipid metastability in vitro of replacing phospholipids with lysolecithin and various free fatty acids. Supersaturated model biles were created with an identical composition (cholesterol saturation index, 1.8; egg yolk lecithin, 34 mM; taurocholate, 120 mM; cholesterol, 25 mM) except for 5%, 10%, or 20% replacement of egg yolk lecithin with a combination of palmitoyl-lysolecithin and a free fatty acid (palmitate, stearate, oleate, linoleate, or arachidonate), followed by time-sequentially monitoring of vesicles and cholesterol crystals using spectrophotometer and video-enhanced differential contrast microscopy. Replacement with hydrophilic fatty acids (linoleate and arachidonate) reduced vesicle formation and promoted cholesterol crystallization, whereas an enhanced cholesterol-holding capacity was evident after replacement with hydrophobic fatty acids (palmitate and stearate). These results indicate that the effect of phospholipase A2 on bile lithogenecity is modulated by the fatty acid species in bile phospholipids, and therefore, that the role of phospholipase A2 in cholesterol gallstone formation is dependent, in part, on biliary phospholipid species selection at the site of hepatic excretion.

Agents for gallstone dissolution.

PubMed

Pitt, H A; McFadden, D W; Gadacz, T R

1987-02-01

Numerous methods are presently available for gallstone dissolution, including oral bile salts; cholesterol solvents such as mono-octanoin and methyl tert-butyl ether; calcium or pigment solvents such as EDTA and polysorbate; mechanical extraction techniques through a T-tube tract or after endoscopic sphincterotomy; or fragmentation methods such as ultrasonography or electrohydraulic lithotripsy, lasers, and extracorporeal shock waves. Which, if any, of these methods will be appropriate for an individual patient depends on the type of stones, whether they are in the gallbladder or bile ducts, whether access to the biliary tree is available, the patient's age and general medical condition, and the availability of expert radiologists, endoscopists, and newer equipment. In the United States, the only available oral bile salt for cholesterol gallstone dissolution is chenodeoxycholate. Ursodeoxycholate, which is more rapid and less toxic, has not been approved by the Federal Drug Administration. These agents are most effective in thin women with small, floating, radiolucent cholesterol gallstones in a functioning gallbladder. Only about half of this small subset of patients, however, will experience partial or complete dissolution of stones in 6 to 12 months. Moreover, recurrence is very likely, and the potential toxicity of long-term therapy is unknown. Thus, for most patients, cholecystectomy remains the most cost-effective and, perhaps, safest option. Intragallbladder instillation of methyl tert-butyl ether and extracorporeal shock wave therapy are also likely to be applicable to only small subsets of patients and to be associated with high recurrence rates. In patients with retained ductal cholesterol stones and access to the biliary tree, mono-octanoin therapy is advantageous in that it can be begun as soon as cholangiography demonstrates no extravasation. In properly selected patients, a 90 percent success rate with mono-octanoin infusion can be expected within a week. Radiologic or endoscopic extraction techniques require maturation of a relatively straight T-tube tract but are not dependent on the type of stone. In the hands of experts, these techniques are highly successful. In postcholecystectomy patients without access to the biliary tree, endoscopic sphincterotomy has become the preferred method of management and can be expected to succeed in more than 90 percent of patients. At this point, the exact role for ultrasonic or electrohydraulic lithotripsy and lasers is unknown. However, these techniques may be applicable in the future in patients with retained bile duct stones in whom extraction and infusion techniques have failed.

BACKGROUND Approximately 10-15% of the adult population suffer from gallstone disease, cholelithiasis, with more women than men being affected. Cholecystectomy is the treatment of choice for people who present with biliary pain or acute cholecystitis and evidence of gallstones. However, some people do not experience a recurrence after an initial episode of biliary pain or cholecystitis. As most of the current research focuses on the surgical management of the disease, less attention has been dedicated to the consequences of conservative management. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management in people presenting with uncomplicated symptomatic gallstones (biliary pain) or cholecystitis. DATA SOURCES We searched all major electronic databases (e.g. MEDLINE, EMBASE, Science Citation Index, Bioscience Information Service, Cochrane Central Register of Controlled Trials) from 1980 to September 2012 and we contacted experts in the field. REVIEW METHODS Evidence was considered from randomised controlled trials (RCTs) and non-randomised comparative studies that enrolled people with symptomatic gallstone disease (pain attacks only and/or acute cholecystitis). Two reviewers independently extracted data and assessed the risk of bias of included studies. Standard meta-analysis techniques were used to combine results from included studies. A de novo Markov model was developed to assess the cost-effectiveness of the interventions. RESULTS Two Norwegian RCTs involving 201 participants were included. Eighty-eight per cent of people randomised to surgery and 45% of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications [risk ratio = 6.69; 95% confidence interval (CI) 1.57 to 28.51; p = 0.01], in particular acute cholecystitis (risk ratio = 9.55; 95% CI 1.25 to 73.27; p = 0.03), and less likely to undergo surgery (risk ratio = 0.50; 95% CI 0.34 to 0.73; p = 0.0004), experience surgery-related complications (risk ratio = 0.36; 95% CI 0.16 to 0.81; p = 0.01) or, more specifically, minor surgery-related complications (risk ratio = 0.11; 95% CI 0.02 to 0.56; p = 0.008) than those randomised to surgery. Fifty-five per cent of people randomised to observation did not require an operation during the 14-year follow-up period and 12% of people randomised to cholecystectomy did not undergo the scheduled operation. The results of the economic evaluation suggest that, on average, the surgery strategy costs £1236 more per patient than the conservative management strategy but was, on average, more effective. An increase in the number of people requiring surgery while treated conservatively corresponded to a reduction in the cost-effectiveness of the conservative strategy. There was uncertainty around some of the parameters used in the economic model. CONCLUSIONS The results of this assessment indicate that cholecystectomy is still the treatment of choice for many symptomatic people. However, approximately half of the people in the observation group did not require surgery or suffer complications in the long term indicating that a conservative therapeutic approach may represent a valid alternative to surgery in this group of people. Owing to the dearth of current evidence in the UK setting a large, well-designed, multicentre trial is needed. STUDY REGISTRATION The study was registered as PROSPERO CRD42012002817.

Gallbladder perforation often occurs during laparoscopic cholecystectomy. The frequency and causes of gallbladder perforation as well as the relevant clinical background factors were investigated in 110 patients undergoing laparoscopic cholecystectomy. We also evaluated intraperitoneal contamination by bacteria and gallstones at the time of gallbladder perforation and investigated whether perforation caused early or late postoperative complications. Intraoperative gallbladder perforation occurred in 29 of the 110 patients (26.3%). It was caused by injury with an electric knife during dissection of the gallbladder bed, injury during gallbladder retraction with grasping forceps, injury during gallbladder extraction from the abdomen, and slippage of cystic duct clips (potentially causing bile and stone spillage). Perforation was more frequent in patients with positive bile cultures and in those with pigment stones (p < 0.02), but not in patients with cholecystitis or cystic duct obstruction. The peritoneal cavity was contaminated by bacteria in 11/29 patients (37.9%) and by spilled stones in 3/29 patients (10.3%). There was no difference in the incidence of postoperative complications between the patients with and without perforation either in the early postoperative period or during follow-up for 24-42 months. Only one patient developed abdominal pain and fever in the early postoperative period, and they were probably related to perforation. Although gallbladder perforation is sometimes unavoidable during laparoscopic cholecystectomy, the risk of severe complications appears to be minimized by early closure of perforation, retrieval of as many of the spilled stones as possible, and intraperitoneal lavage.

Indications and complications of splenectomy for children with sickle cell disease.

Al-Salem, Ahmed H

2006-11-01

Sickle cell anemia (SCA), which is characterized by high hemoglobin (Hb) F level and persistent splenomegaly into the older age group (up to 18 years of age) or even adults, is one of the commonest hemoglobinopathies in the Eastern Province of Saudi Arabia. This makes them liable to develop splenic complications requiring splenectomy. This is a review of our experience in the management of 134 children with SCA who had splenectomy as part of their management at our hospital, with emphasis given to the indications and complications of splenectomy. The medical records of all children who had splenectomy at our hospital were retrospectively reviewed for the following: age at splenectomy, sex, Hb electrophoresis, indication for splenectomy, preoperative investigations, type of surgery, spleen weight, histology, perioperative management, and postoperative complications. From 1990 to 2004, 170 children with various hematologic disorders had splenectomy at our hospital. Of these, 134 had SCA (118 had sickle cell disease and 16 had sickle-beta-thalassemia). Recurrent acute splenic sequestration crisis (ASSC) was the commonest indication for splenectomy in 103 (76.9%) patients, followed by hypersplenism in 18 (13.4%). Seven (5.2%) of our patients had splenectomy for splenic abscess (SA) and 2 had splenectomy for massive splenic infarction; 103 (61 boys, 42 girls) patients with a mean age of 7.6 years (range, 1.8-13 years) had splenectomy for ASSC. Their mean Hb F level was 20.5% (range, 9.2%-39.6%). Thirty-two of them had major attacks. Their Hb levels at the time of admission ranged from 1.4 to 4.1 g/dL (mean, 2.5 g/dL). The remaining 71 had minor recurrent attacks. Eighteen had splenectomy for hypersplenism and all had a significant increase in their blood parameters after splenectomy. Seven had splenectomy for SA. In 5 patients, Salmonella was the causative organism; in 1, it was Enterobacter sakazaki, whereas in 1, no organisms were identified. Two of our patients had splenectomy for massive splenic infarction because of persistent left upper quadrant abdominal pain, and 1 had splenectomy for splenomegaly with a nonfunctioning spleen. Twenty-eight (21%) of our patients had splenectomy and cholecystectomy. In 4 patients, this was because of symptomatic gallstones, whereas in the other 24, it was because of asymptomatic gallstones discovered on ultrasound. There was no mortality, but 8 (6%) developed postoperative complications. With good perioperative management, splenectomy in children with SCA is not only safe, but also beneficial in treating SA, reducing the patients' transfusion requirements, eliminating the risks of ASSC, and eliminating the discomfort and mechanical pressure of the enlarged spleen. Abdominal ultrasound should be done routinely preoperatively for all children with SCA undergoing splenectomy, and if gallstones are discovered, they should undergo concomitant cholecystectomy. This is even so for asymptomatic gallstones. The addition of cholecystectomy to splenectomy does not increase the morbidity, but eliminates the subsequent complications of gallstones and simplifies their future management in case of abdominal crisis as the possibility of cholecystitis is eliminated.

A 4.75-year old Simmental cow was presented with symptoms of colic and ileus. The clinical signs and blood analysis resulted in the diagnosis of suspected primary hypoadrenocorticism (Addison's disease). Although Addison's disease has been frequently described in other domestic mammals, to our knowledge, this disease has not previously been reported in cattle.

The meconium disease represents a problem of great impact over the vital prognosis of the newborn, the mortality of this disease being rated in various studies between 30 and 50%. The meconial disease that reunites the meconial ileus and the meconial peritonitis is often associated with cystic fibrosis a disease of general impact over the entire organism increasing the gravity and influencing the vital prognosis of these patients. The authors' purpose is to evaluate the results obtained after the treatment of the meconial disease in the Pediatric Surgery Clinic of the Emergency Hospital of Craiova over a period of 10 years. The study has been made on a number of 16 cases of meconial ileus, plug and peritonitis analising the difficulty of the diagnostic process, the preoperative care as well as the possibilities of surgical treatment. The surgical treatment is composed of multiple procedures including simple suture of the bowel defect and segmentary bowel resections with primary anastomosis and/or secondary anastomosis after ileostoma. The mortality on the studied cases was of 37.5% despite recent progresses achieved in postoperative care of these type of patients.

We herein report a case of abdominal actinomycosis in a 12-year-old girl in whom an omental primary tumor was suspected before surgery. The patient began to experience intermittent lower left abdominal pain. Abdominal computed tomography (CT) scans were inconclusive at this time, but 6 months later, CT and magnetic resonance imaging (MRI) examinations showed a 7-cm, tumor-like lesion in the left abdominal cavity; malignancy could not be ruled out. The tumor, which originated in the omentum and adhered strongly to the left abdominal wall, was resected along with approximately 90 % of the omentum, the peritoneum in contact with the mass, and the posterior layer of the rectus abdominal sheath, under suspicion of a malignant tumor. However, omental actinomycosis was the final pathological diagnosis. The patient's antibiotic treatment was changed to a penicillin-series oral antibiotic to prevent recurrence of the actinomycosis. The patient was discharged from our hospital 16 days after the first surgery, but she developed three episodes of ileus; the first two required surgery. The patient has had no further recurrences of actinomycosis or postoperative ileus 20 months after discharge.

Endoscopic sphincterotomy (EST) with stone extraction is the standard management for choledocholithiasis. However, the necessity for subsequent management of gallstone to prevent the biliary complications remained controversial and few data were evaluated for the impact of status of gallbladder on recurrent biliary complications. We retrospectively investigated the relationship between the status of gallbladder and the occurrence of biliary complications after endoscopic removal of choledocholithiasis. Between January 1998 and December 2008, we enrolled 453 patients with intact gallbladder who underwent EST for choledocholithiasis and allocated into two groups: calculous gallbladder (n = 256) and acalculous gallbladder (n = 197). By reviewing patients' medical records, we compared the occurrence of biliary complications according to the presence or absence of gallstone in GB in situ. In total, biliary complications occurred in 83 patients (18.3 %) during the follow-up period. Calculous GB group had higher rate of overall complications (22.7 vs. 12.7 %; p = 0.007) and GB-associated complications (11.3 vs. 2.5 %; p = 0.001) than acalculous GB group. On the multivariate analysis, only the presence of gallstone was shown to be significant risk factor for overall biliary complication (OR 2.029; 95 % CI 1.209-3.405; p = 0.007) and GB-associated complications (OR 5.077; 95 % CI 1.917-13.446; p = 0.001). Mean event-free period was shorter in calculous GB group than acalculous GB group for overall complications (1774 vs. 2159 days; p = 0.012) and GB-associated complication (2153 vs. 2591 days; p = 0.001). Prophylactic cholecystectomy may not be necessary to prevent biliary complication in patients with acalculous gallbladder after endoscopic removal of pigment stones from bile duct.

Narayana Kalkura, S.; Natarajan, Subramanian

Among the various crystallization techniques, crystallization in gels has found wide applications in the fields of biomineralization and macromolecular crystallization in addition to crystallizing materials having nonlinear optical, ferroelectric, ferromagnetic, and other properties. Furthermore, by using this method it is possible to grow single crystals with very high perfection that are difficult to grow by other techniques. The gel method of crystallization provides an ideal technique to study crystal deposition diseases, which could lead to better understanding of their etiology. This chapter focuses on crystallization in gels of compounds that are responsible for crystal deposition diseases. The introduction is followed by a description of the various gels used, the mechanism of gelling, and the fascinating phenomenon of Liesegang ring formation, along with various gel growth techniques. The importance and scope of study on crystal deposition diseases and the need for crystal growth experiments using gel media are stressed. The various crystal deposition diseases, viz. (1) urolithiasis, (2) gout or arthritis, (3) cholelithiasis and atherosclerosis, and (4) pancreatitis and details regarding the constituents of the crystal deposits responsible for the pathological mineralization are discussed. Brief accounts of the theories of the formation of urinary stones and gallstones and the role of trace elements in urinary stone formation are also given. The crystallization in gels of (1) the urinary stone constituents, viz. calcium oxalate, calcium phosphates, uric acid, cystine, etc., (2) the constituents of the gallstones, viz. cholesterol, calcium carbonate, etc., (3) the major constituent of the pancreatic calculi, viz., calcium carbonate, and (4) cholic acid, a steroidal hormone are presented. The effect of various organic and inorganic ions, trace elements, and extracts from cereals, herbs, and fruits on the crystallization of major urinary stone and gallstone constituents are described. In addition, tables of gel-grown organic and inorganic crystals are provided.

The aim of this study was to assess whether cholecystectomy can decrease the recurrent pancreatitis in the elderly patients who received endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) and successful clearance of bile duct (BD) stones after gallstone-related acute pancreatitis. We analyzed data from National Health Insurance Research Database of Taiwan. Elderly patients (age ≧70 years old) who had gallstone-related acute pancreatitis and underwent successful EST with BD stones clearance were eligible for enrollment. This nationwide, population-based, propensity score (PS)-matched cohort study involved two cohorts: (1) patients who underwent cholecystectomy after ERCP with BD stone clearance as study group and (2) those who adopted wait-and-see strategy (without cholecystectomy) after ERCP with BD stone clearance as control group. The primary and secondary endpoints were recurrent acute pancreatitis and all-cause mortality, respectively. During the study period, a total of 670 elderly patients (male 291, female 379) with a mean age of 79.1 was enrolled for analysis after PS matching. The incidence rate of recurrent acute pancreatitis was 12.39 per 1000 person-years in the cholecystectomy cohort and 23.94 per 1000 person-years in the PS-matched control cohort. The risk of recurrent acute pancreatitis was significantly lower in the cholecystectomy cohort (HR, 0.56; 95 % confidence interval [CI], 0.34-0.91; P = 0.021). The HR for all-cause mortality among the cholecystectomy cohort was 0.75 (95 % CI, 0.59-0.95; P = 0.016) compared with the control cohort. Cholecystectomy decreased the subsequent recurrent acute pancreatitis and the all-cause mortality in elderly patients with EST and clearance of BD stones after gallstone-related acute pancreatitis.

The causal association between diabetes and pancreatic cancer remains unclear in Asian populations. This study examined whether gallstones, a cholecystectomy, chronic pancreatitis and the treatment of antidiabetic agents affect the risk of subsequent pancreatic cancer for patients with diabetes in a Taiwanese population. Using claims data from the universal health insurance program in Taiwan, 449,685 newly diagnosed diabetic cases among insured people from 2000 to 2003 were identified as the case group. The comparison group, matched for gender, age, and the index year of the diabetes cohort, consisted of 325,729 persons without diabetes. Pancreatic cancer incidence was measured in both groups until the end of 2008. Other risk factors associated with this cancer were also measured. The incidence of pancreatic cancer in the diabetic cohort was 2-fold greater than that in the comparison group (1.46 vs. 0.71 per 10,000 person-years) with an adjusted hazard ratio (HR) of 1.75 [95 % confidence interval (CI) 1.45-2.10]. The risk slightly increased for diabetic patients with gallstones, cholecystitis, and a cholecystectomy (HR 1.92, 95% CI 1.18-3.11), but greatly increased for those with comorbidity of chronic pancreatitis (HR 22.9, 95% CI 12.6-41.4). Pancreatic cancer risk also increased significantly for those patients who used more insulin for treating diabetes (OR 2.20, 95% CI 1.40-3.45). Our data suggest that the risk of pancreatic cancer is moderately increased in patients with diabetes, especially those using insulin therapy. The risk is greatly increased for diabetic patients with chronic pancreatitis.

Pigment gallstone pathogenesis: slime production by biliary bacteria is more important than beta-glucuronidase production.

Pigment stones are thought to form as a result of deconjugation of bilirubin by bacterial beta-glucuronidase, which results in precipitation of calcium bilirubinate. Calcium bilirubinate is then aggregated into stones by an anionic glycoprotein. Slime (glycocalyx), an anionic glycoprotein produced by bacteria causing foreign body infections, has been implicated in the formation of the precipitate that blocks biliary stents. We previously showed that bacteria are present within the pigment portions of gallstones and postulated a bacterial role in pigment stone formation through beta-glucuronidase or slime production. Ninety-one biliary bacterial isolates from 61 patients and 12 control stool organisms were tested for their production of beta-glucuronidase and slime. The average slime production was 42 for biliary bacteria and 2.5 for stool bacteria (P <0.001). Overall, 73% of biliary bacteria and 8% of stool bacteria produced slime (optical density >3). In contrast, only 38% of biliary bacteria produced beta-glucuronidase. Eighty-two percent of all patients, 90% of patients with common bile duct (CBD) stones, 100% of patients with primary CBD stones, and 93% of patients with biliary tubes had one or more bacterial species in their stones that produced slime. By comparison, only 47% of all patients, 60% of patients with CBD stones, 62% of patients with primary CBD stones, and 50% of patients with biliary tubes had one or more bacteria that produced beta-glucuronidase. Most biliary bacteria produced slime, and slime production correlated better than beta-glucuronidase production did with stone formation and the presence of biliary tubes or stents. Patients with primary CBD stones and biliary tubes had the highest incidence of slime production. These findings suggest that bacterial slime is important in gallstone formation and the blockage of biliary tubes.

Recently, complications in patients with nontransfusion-dependent thalassemia (NTDT), in particular those with β-thalassemia intermedia (β-TI), were found to be significantly different from those in patients with transfusion dependent thalassemia (TDT), mainly β-thalassemia major (β-TM). However, this information is rather limited in other forms of NTDT. In this prospective study, adult Thai NTDT patients were interviewed and clinically evaluated for thalassemia related complications. Fifty-seven NTDT patients (age 18-74 years), 59.6% Hb E/β-thalassemia and 40.4% Hb H disease, were recruited; 26.4% were splenectomized. The most common complications were gallstones (68.4%), osteoporosis (26.3%), and pulmonary hypertension (15.8%). Splenectomy was associated with higher rate of gallstones and serious infection (P = .001 and .052, respectively), consistent with a multivariate analysis (RR = 9.5, P = .044, and RR = 15.1, P = .043, respectively). In addition, a higher hemoglobin level was inversely associated with gallstones in both univariate and multivariate analyses (P = .01 and .022, respectively). Serum ferritin was associated with abnormal liver function (P = .002). In contrast to the previous study, the prevalence of thrombosis was less common in our population (1.7%), probably due to differences in transfusion therapy, ethnicity, and underlying genotypes. For the first time, this prospective study provided the current prevalence of NTDT related complications in a Southeast Asian population with a different underlying genetic basis compared with previous studies. Although individual prevalence of each complication might differ from other studies, several important clinical factors such as splenectomy, degree of anemia, and iron overload seem to be determining risks of developing these complications consistently across different ethnicities. © 2018 Wiley Periodicals, Inc.

Impact of ursodeoxycholic acid on a CCK1R cholesterol-binding site may contribute to its positive effects in digestive function

Dysfunction of the type 1 cholecystokinin (CCK) receptor (CCK1R) as a result of increased gallbladder muscularis membrane cholesterol has been implicated in the pathogenesis of cholesterol gallstones. Administration of ursodeoxycholic acid, which is structurally related to cholesterol, has been shown to have beneficial effects on gallstone formation. Our aims were to explore the possible direct effects and mechanism of action of bile acids on CCK receptor function. We studied the effects of structurally related hydrophobic chenodeoxycholic acid and hydrophilic ursodeoxycholic acid in vitro on CCK receptor function in the setting of normal and elevated membrane cholesterol. We also examined their effects on a cholesterol-insensitive CCK1R mutant (Y140A) disrupting a key site of cholesterol action. The results show that, similar to the impact of cholesterol on CCK receptors, bile acid effects were limited to CCK1R, with no effects on CCK2R. Chenodeoxycholic acid had a negative impact on CCK1R function, while ursodeoxycholic acid had no effect on CCK1R function in normal membranes but was protective against the negative impact of elevated cholesterol on this receptor. The cholesterol-insensitive CCK1R mutant Y140A was resistant to effects of both bile acids. These data suggest that bile acids compete with the action of cholesterol on CCK1R, probably by interacting at the same site, although the conformational impact of each bile acid appears to be different, with ursodeoxycholic acid capable of correcting the abnormal conformation of CCK1R in a high-cholesterol environment. This mechanism may contribute to the beneficial effect of ursodeoxycholic acid in reducing cholesterol gallstone formation. PMID:26138469

Understanding patient perspectives regarding shared decision-making is crucial to providing informed, patient-centered care. Little is known about perceptions of vulnerable patients regarding shared decision-making during surgical consultation. The purpose of this study was to evaluate whether a validated tool reflects perceptions of shared decision-making accurately among patients seeking surgical consultation for gallstones at a safety-net hospital. A mixed methods study was conducted in a sample of adult patients with gallstones evaluated at a safety-net surgery clinic between May to July 2016. Semi-structured interviews were conducted after their initial surgical consultation and analyzed for emerging themes. Patients were administered the Shared Decision-Making Questionnaire and Autonomy Preference Scale. Univariate analyses were performed to identify factors associated with shared decision-making and to compare the results of the surveys to those of the interviews. The majority of patients (N = 30) were female (90%), Hispanic (80%), Spanish-speaking (70%), and middle-aged (45.7 ± 16 years). The proportion of patients who perceived shared decision-making was greater in the Shared Decision-Making Questionnaire versus the interviews (83% vs 27%, P < .01). Age, sex, race/ethnicity, primary language, diagnosis, Autonomy Preference Scale score, and decision for operation was not associated with shared decision-making. Contributory factors to this discordance include patient unfamiliarity with shared decision-making, deference to surgeon authority, lack of discussion about different treatments, and confusion between aligned versus shared decisions. Available questionnaires may overestimate shared decision-making in vulnerable patients suggesting the need for alternative or modifications to existing methods. Furthermore, such metrics should be assessed for correlation with patient-reported outcomes, such as satisfaction with decisions and health status. Copyright © 2017 Elsevier Inc.

Intestinal manipulation (IM) during abdominal surgery results in intestinal inflammation leading to hypomotility or ileus. Mast cell activation is thought to play a crucial role in the pathophysiology of postoperative ileus (POI). However, this conclusion was mainly drawn using mast cell-deficient mouse models with abnormal Kit signaling. These mice also lack interstitial cells of Cajal (ICC) resulting in aberrant gastrointestinal motility even prior to surgery, compromising their use as model to study POI. To avoid these experimental weaknesses we took advantage of a newly developed knock-in mouse model, Cpa3(Cre/+) , devoid of mast cells but with intact Kit signaling. The role of mast cells in the development of POI and intestinal inflammation was evaluated assessing gastrointestinal transit and muscularis externa inflammation after IM in two strains of mice lacking mast cells, i.e. Kit(W-sh/W-sh) and Cpa3(Cre/+) mice, and by use of the mast cell stabilizer cromolyn. Kit(W-sh/W-sh) mice lack ICC networks and already revealed significantly delayed gastrointestinal transit even before surgery. IM did not further delay intestinal transit, but induced infiltration of myeloperoxidase positive cells, expression of inflammatory cytokines and recruitment of monocytes and neutrophils into the muscularis externa. On the contrary, Cpa3(Cre/+) mice have a normal network of ICC and normal gastrointestinal. Surprisingly, IM in Cpa3(Cre/+) mice caused delay in gut motility and intestinal inflammation as in wild type littermates mice (Cpa3(+/+) ). Furthermore, treatment with the mast cell inhibitor cromolyn resulted in an inhibition of mast cells without preventing POI. Here, we confirm that IM induced mast cell degranulation. However, our data demonstrate that mast cells are not required for the pathogenesis of POI in mice. Although there might be species differences between mouse and human, our results argue against mast cell inhibitors as a therapeutic approach to shorten POI.

To avoid these experimental weaknesses we took advantage of a newly developed knock-in mouse model, Cpa3Cre/+, devoid of mast cells but with intact Kit signaling. Design The role of mast cells in the development of POI and intestinal inflammation was evaluated assessing gastrointestinal transit and muscularis externa inflammation after IM in two strains of mice lacking mast cells, i.e. KitW-sh/W-sh and Cpa3Cre/+ mice, and by use of the mast cell stabilizer cromolyn. Results KitW-sh/W-sh mice lack ICC networks and already revealed significantly delayed gastrointestinal transit even before surgery. IM did not further delay intestinal transit, but induced infiltration of myeloperoxidase positive cells, expression of inflammatory cytokines and recruitment of monocytes and neutrophils into the muscularis externa. On the contrary, Cpa3Cre/+ mice have a normal network of ICC and normal gastrointestinal. Surprisingly, IM in Cpa3Cre/+ mice caused delay in gut motility and intestinal inflammation as in wild type littermates mice (Cpa3+/+). Furthermore, treatment with the mast cell inhibitor cromolyn resulted in an inhibition of mast cells without preventing POI. Conclusions Here, we confirm that IM induced mast cell degranulation. However, our data demonstrate that mast cells are not required for the pathogenesis of POI in mice. Although there might be species differences between mouse and human, our results argue against mast cell inhibitors as a therapeutic approach to shorten POI. PMID:24416383

Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

Total cholesterol, total bilirubin, calcium, oxalate, inorganic phosphate, magnesium, iron, copper, sodium and potassium were analyzed quantitatively in gallstones, bile of gall bladder and sera of 200 patients of cholelithiasis (52 cholesterol, 76 mixed and 72 pigment stone patients) and their contents were correlated between calculi and bile and sera and bile in these three type of stone patients. A significant positive correlation was observed between total cholesterol, total bilirubin of calculi and bile, copper of bile and sera of cholesterol stone patients, copper of calculi and bile, total bilirubin, oxalate, magnesium, potassium of sera and bile of pigment stone patients and oxalate and iron of stone and bile, total bilirubin, oxalate, sodium of sera and bile of mixed stone patients. A significant negative correlation was found between magnesium of serum and bile of cholesterol stone patients, oxalate of calculi and bile of pigment stone patients and magnesium of serum and bile of mixed stone patients.

Pressures in the sphincter of Oddi in patients with gallstones, common duct stones, and recurrent pancreatitis.

To determine the significance of manometric pressure, measurements of the sphincter of Oddi in a control group and in patients with cholelithiasis with common duct stones with and without recurrent pancreatitis were studied. Sphincter of Oddi pressure was recorded continuously and by station pull-through by a triple lumen catheter. The basal sphincter of Oddi pressure, the mean pressure gradient between common duct and duodenum, and the sphincter of Oddi wave amplitude were measured. There was no significant difference between control subjects and patients with gallstones and common duct stones. In patients with common duct stones and recurrent pancreatitis the basal sphincter of Oddi pressure, the pressure gradient between common duct and duodenum, and the wave amplitude were significantly increased over control patients. These studies suggest that abnormalities in the sphincter of Oddi motor function are more common in patients with common duct stones with recurrent pancreatitis than in similar patients without pancreatitis.

Gastroenterological emergencies in the tropics.

PubMed

Cook, G C

1991-12-01

Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.

Current state of laparoscopic parastomal hernia repair: A meta-analysis.

2015-07-28

To evaluate the efficacy and safety of the laparoscopic approaches for parastomal hernia repair reported in the literature. A systematic review of PubMed and MEDLINE databases was conducted using various combination of the following keywords: stoma repair, laparoscopic, parastomal, and hernia. Case reports, studies with less than 5 patients, and articles not written in English were excluded. Eligible studies were further scrutinized with the 2011 levels of evidence from the Oxford Centre for Evidence-Based Medicine. Two authors reviewed and analyzed each study. If there was any discrepancy between scores, the study in question was referred to another author. A meta -analysis was performed using both random and fixed-effect models. Publication bias was evaluated using Begg's funnel plot and Egger's regression test. The primary outcome analyzed was recurrence of parastomal hernia. Secondary outcomes were mesh infection, surgical site infection, obstruction requiring reoperation, death, and other complications. Studies were grouped by operative technique where indicated. Except for recurrence, most postoperative morbidities were reported for the overall cohort and not by approach so they were analyzed across approach. Fifteen articles with a total of 469 patients were deemed eligible for review. Most postoperative morbidities were reported for the overall cohort, and not by approach. The overall postoperative morbidity rate was 1.8% (95%CI: 0.8-3.2), and there was no difference between techniques. The most common postoperative complication was surgical site infection, which was seen in 3.8% (95%CI: 2.3-5.7). Infected mesh was observed in 1.7% (95%CI: 0.7-3.1), and obstruction requiring reoperation also occurred in 1.7% (95%CI: 0.7-3.0). Other complications such as ileus, pneumonia, or urinary tract infection were noted in 16.6% (95%CI: 11.9-22.1). Eighty-one recurrences were reported overall for a recurrence rate of 17.4% (95%CI: 9.5-26.9). The recurrence rate was 10.2% (95%CI: 3.9-19.0) for the modified laparoscopic Sugarbaker approach, whereas the recurrence rate was 27.9% (95%CI: 12.3-46.9) for the keyhole approach. There were no intraoperative mortalities reported and six mortalities during the postoperative course. Laparoscopic intraperitoneal mesh repair is safe and effective for treating parastomal hernia. A modified Sugarbaker approach appears to provide the best outcomes.

To evaluate the methods and outcome of gallbladder preservation in surgical treatment of primary bile duct stones. Thirty-five patients with primary bile duct stones and intact gallbladders received stone extraction by two operative approaches, 23 done through the intrahepatic duct stump (RBD-IDS, the RBD-IDS group) after partial hepatectomy and 12 through the hepatic parenchyma by retrograde puncture (RBD-RP, the RBD-RP group). The gallbladders were preserved and the common bile duct (CBD) incisions were primarily closed. The patients were examined postoperatively by direct cholangiography and followed up by ultrasonography once every six months. In the RBD-IDS group, residual bile duct stones were found in three patients, which were cleared by a combination of fibrocholedochoscopic extraction and lithotripsy through the drainage tracts. The tubes were removed on postoperative day 22 (range: 16-42 days). In the RBD-RP group, one patient developed hemobilia and was cured by conservative therapy. The tubes were removed on postoperative day 8 (range: 7-11 days). Postoperative cholangiography showed that all the gallbladders were well opacified, contractile and smooth. During 54 (range: 6-120 months) months of follow-up, six patients had mildly thickened cholecystic walls without related symptoms and further changes, two underwent laparotomies because of adhesive intestinal obstruction and gastric cancer respectively, three died of cardiopulmonary diseases. No stones were found in all the preserved gallbladders. The intact gallbladders preserved after surgical extraction of primary bile duct stones will not develop gallstones. Retrograde biliary drainage is an optimal approach for gallbladder preservation.

Gastrointestinal and hepatic complications of sickle cell disease.

Sickle cell disease (SCD) is an autosomal recessive abnormality of the beta-globin chain of hemoglobin (Hb), resulting in poorly deformable sickled cells that cause microvascular occlusion and hemolytic anemia. The spleen is almost always affected by SCD, with microinfarcts within the first 36 months of life resulting in splenic atrophy. Acute liver disorders causing right-sided abdominal pain include acute vaso-occlusive crisis, liver infarction, and acute hepatic crisis. Chronic liver disease might be due to hemosiderosis and hepatitis and possibly to SCD itself if small, clinically silent microvascular occlusions occur chronically. Black pigment gallstones caused by elevated bilirubin excretion are common. Their small size permits them to travel into the common bile duct but cause only low-grade obstruction, so hyperbilirubinemia rather than bile duct dilatation is typical. Whether cholecystectomy should be done in asymptomatic individuals is controversial. The most common laboratory abnormality is an elevation of unconjugated bilirubin level. Bilirubin and lactate dehydrogenase levels correlate with one another, suggesting that chronic hemolysis and ineffective erythropoiesis, rather than liver disease, are the sources of hyperbilirubinemia. Abdominal pain is very common in SCD and is usually due to sickling, which resolves with supportive care. Computed tomography scans might be ordered for severe or unremitting pain. The liver typically shows sickled erythrocytes and Kupffer cell enlargement acutely and hemosiderosis chronically. The safety of liver biopsies has been questioned, particularly during acute sickling crisis. Treatments include blood transfusions, exchange transfusions, iron-chelating agents, hydroxyurea, and allogeneic stem-cell transplantation. Copyright 2010 AGA Institute. Published by Elsevier Inc.

Neonatal leukemia is a rare disease with an estimated prevalence of about one to five in a million neonates. The majority being acute myeloid leukemia (AML), neonatal leukemia can present with a variety of symptoms including hyperleucocytosis, cytopenia, hepatosplenomegaly, and skin infiltrates. Chromosomal rearrangements including mixed lineage leukemia (MLL) translocations are common in neonatal AML. A female neonate born at 34 weeks gestation presented with cardiorespiratory failure, hepatosplenomegaly, pancytopenia, and coagulopathy. She required intensive care treatment including mechanical ventilation, high-dose catecholamine therapy, and multiple transfusions. Small intestinal biopsy obtained during laparotomy for meconium ileus revealed an infiltrate by an undifferentiated monoblastic, MLL-rearranged leukemia. No other manifestations of leukemia could be detected. After spontaneous clinical remission, lasting 5 months without any specific treatment, the patient presented with leukemia cutis and full-blown monoblastic leukemia. MLL-AF10-rearranged AML could be re-diagnosed and successfully treated with chemotherapy and hematopoietic stem cell transplantation. Our patient exhibited a unique manifestation of neonatal MLL-AF10 rearranged AML with cardiorespiratory failure and intestinal infiltration. It highlights the importance of leukemia in the differential diagnosis of neonatal distress, congenital hematological abnormalities, and skin lesions.

Percutaneous Nephrolithotomy in Autosomal Dominant Polycystic Kidney Disease: Is it Different from Percutaneous Nephrolithotomy in Normal Kidney?

Nephrolithiasis has been reported in 20-28% of patients, of whom 50% are symptomatic for stone disease and 20% require definite urologic intervention. The management of nephrolithiasis includes oral alkali dissolution therapy, extracorporeal shock wave lithotripsy and surgical treatment. In such patients, percutaneous nephrolithotomy (PNL) as a method of stone treatment has been reported in few cases with limited experience. The aim of this study is to present our experience of PNL in autosomal dominant polycystic kidney disease (ADPKD) and assessing the outcome results. From 2002 to 2011, 22 patients (26 renal units) suffering from ADPKD with stone were managed by PNL. Demographic characteristics, operative parameters and postoperative complications were recorded and analysed. The overall success rate of PNL was 82.1% and PNL with extracorporeal shock wave lithotripsy for clinically significant residual fragments was 92.85% respectively. The hematuria required blood transfusion (n = 9), postoperative fever due to cyst infection (n = 4) and paralytic ileus (n = 3) were recorded. The PNL in ADPKD PNL is safe and effective but have more postoperative complications such as bleeding requiring transfusions, fever due to cyst infection and paralytic ileus.

In recent years, the use of laparoscopic techniques for surgical operations has been increasing, because this procedure is less invasive and is excellent in regard to patient's quality of life. Normally, complications are rare in laparoscopic surgery. However, we experienced a case of pulmonary embolism and one case of ileus as complications after laparoscopic radical prostatectomy. Especially, in this type of operation, the danger of complications is increased due to the severe head down and lithotomy position, which is employed to ensure a good view during operation. In this particular case, the long duration of operation may have been another related risk factor. There were no risk factors for pulmonary embolism such as those encountered when a patient is aged, obese, or bed ridden for a long time. However, an intermittent air massage must be applied to the lower legs to prevent thrombus due to poor blood circulation of the lower extremities below the knee during the surgery. It is also necessary to change the posture of the patient frequently after the operation. In addition, the administration of low molecular weight heparin may also be effective.

Hepatic Deletion of SIRT1 Decreases Hepatocyte Nuclear Factor 1α/Farnesoid X Receptor Signaling and Induces Formation of Cholesterol Gallstones in Mice

SIRT1, a highly conserved NAD+-dependent protein deacetylase, is a key metabolic sensor that directly links nutrient signals to animal metabolic homeostasis. Although SIRT1 has been implicated in a number of hepatic metabolic processes, the mechanisms by which hepatic SIRT1 modulates bile acid metabolism are still not well understood. Here we report that deletion of hepatic SIRT1 reduces the expression of farnesoid X receptor (FXR), a nuclear receptor that regulates bile acid homeostasis. We provide evidence that SIRT1 regulates the expression of FXR through hepatocyte nuclear factor 1α (HNF1α). SIRT1 deficiency in hepatocytes leads to decreased binding of HNF1α to the FXR promoter. Furthermore, we show that hepatocyte-specific deletion of SIRT1 leads to derangements in bile acid metabolism, predisposing the mice to development of cholesterol gallstones on a lithogenic diet. Taken together, our findings indicate that SIRT1 plays a vital role in the regulation of hepatic bile acid homeostasis through the HNF1α/FXR signaling pathway. PMID:22290433

To compare the results and outcomes of the laparoscopic cholecystectomy (LC) with the small incision cholecystectomy (SIC). Observational study. Baqiyatallah Hospital, Tehran, Iran, from February 2008 to March 2009. Patients with symptomatic gallstones that were referred and enrolled in the study for LC or SIC. Operation, anaesthesia, analgesics and postoperative care were standardized. The patients were assessed for operation time, postoperative pain, nausea, vomiting, hospital stay, return to work time and complications in the postoperative period on day 1, 1 week, 1 month and 6 months, postoperatively. Of 144 patients, 81 underwent LC and 63 underwent SIC. Both groups were matched for age, gender, BMI, clinical findings and ASA grading. The mean duration of operation was 74 and 62 minutes in the LC and SIC groups, respectively (p = 0.0059). Duration of hospital stay and return to regular activities were shorter after LC compared to SIC. Pain scores, nausea and vomiting were the same in both groups, although the frequency of intra-operative complications were greater in LC compared to SIC. Outcome and complications of SIC were comparable with those of LC.

Acute abdominal pain in patients with lassa fever: Radiological assessment and diagnostic challenges.

To highlight the problems of diagnosis and management of acute abdomen in patients with lassa fever. And to also highlight the need for high index of suspicion of lassa fever in patients presenting with acute abdominal pain in order to avoid surgical intervention with unfavourable prognosis and nosocomial transmission of infections, especially in Lassa fever-endemic regions. A review of experiences of the authors in the management of lassa fever over a 4-year period (2004-2008). Literature on lassa fever, available in the internet and other local sources, was studied in November 2010 and reviewed. Normal plain chest radiographic picture can change rapidly due to pulmonary oedema, pulmonary haemorrhage and acute respiratory distress syndrome. Plain abdominal radiograph may show dilated bowels with signs of paralytic ileus or dynamic intestinal obstruction due to bowel wall haemorrhage or inflamed and enlarged Peyer's patches. Ultrasound may show free intra-peritoneal fluid due to peritonitis and intra-peritoneal haemorrhage. Bleeding into the gall bladder wall may erroneously suggest infective cholecystitis. Pericardial effusion with or without pericarditis causing abdominal pain may be seen using echocardiography. High index of suspicion, antibody testing for lassa fever and viral isolation in a reference laboratory are critical for accurate diagnosis. Patients from lassa fever-endemic regions may present with features that suggest acute abdomen. Radiological studies may show findings that suggest acute abdomen but these should be interpreted in the light of the general clinical condition of the patient. It is necessary to know that acute abdominal pain and vomiting in lassa fever-endemic areas could be caused by lassa fever, which is a medical condition. Surgical option should be undertaken with restraint as it increases the morbidity, may worsen the prognosis and increase the risk of nosocomial transmission.

Implementing a Pro-forma for Multidisciplinary Management of an Enterocutaneous Fistula: A Case Study.

2015-06-01

Optimal management of patients with an entercocutaneous fistula (ECF) requires utilization of the sepsis, nutrition, anatomy, and surgical procedure (SNAP) protocol. The protocol includes early detection and treatment of sepsis, optimizing patient nutrition through oral and parenteral routes, identifying the fistula anatomy, optimal fistula management, and proceeding to corrective surgery when appropriate. The protocol requires multidisciplinary team (MDT) coordination among surgeons, nurses, dietitians, stoma nurses, and physiotherapists. This case study describes a 70-year-old man who developed an ECF subsequent to a laparotomy for a small bowel obstruction. Following a period of ileus, 16 days post laparotomy the patient developed a high-output (2,000 mL per day) fistula. The patient also became pyrexial with raised inflammatory markers, requiring antibiotic treatment. Following development of his ECF, he was managed using the SNAP protocol for the duration of his admission; however, in implementing this protocol with this patient, clinicians noted fluid charts were inadequate to allow effective management of the variables. Thus, a new pro-forma was created that encompassed fluid balance, nutritional status, and pertinent blood test results, as well as perifistular skin condition, medication, and documentation of management plans from the MDT team. The pro-forma was recorded daily in the patient notes. Following implementation of the pro-forma and the SNAP protocol, the patient recovered well clinically over a period of 4 weeks with a decrease in his fistula output to 300-500 mL per day, and he was discharged with plans for further corrective surgery to resect the fistula and for bowel re-anastomoses. Although fluid charts are readily available, they do not include all pertinent variables for optimal management of patients with an ECF. Further research is needed to validate the pro-forma and evaluate its effect on patient outcomes.

There is a growing interest in surgery regarding the balance between appropriate hospital length of stay (LOS) and prevention of unnecessary readmissions. This study examines the relationship between postoperative LOS and unplanned readmission after colorectal resection, exploring whether patients discharged earlier have different readmission risk profiles. Patients undergoing colorectal resection were selected by Common Procedural Terminology (CPT) code from the 2012 ACS National Surgical Quality Improvement Program (NSQIP) database. Patients were stratified by LOS quartile. Kaplan-Meier analysis was used to examine characteristics associated with 30-day unplanned readmission. Factors with a p < 0.1 were included in the Cox proportional hazards model. Subsequently, chi-square analysis compared LOS, patient, and perioperative factors with the primary reason for readmission. Factors with a p < 0.2 were included in a multivariable logistic regression for each readmission reason. For 33,033 patients undergoing colorectal resection, the overall 30-day unplanned readmission rate was 11 %. After adjusting for patient and perioperative factors, a postoperative LOS ≥8 days was associated with a 55 % increase in the relative hazard of readmission. Patients with a ≤3-day LOS were more likely to be readmitted with ileus/obstruction (odds ratio (OR): 1.8, p = 0.001) and pain (OR: 2.2, p = 0.007). LOS was not significantly associated with readmission for intraabdominal infection or medical complications. Patients with longer LOS and complicated hospital courses continue to be high risk post-discharge, while straightforward early discharges have a different readmission risk profile. More targeted readmission prevention strategies are critical to focusing resource utilization for colorectal surgery patients.

Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p < 0.005) and operations (p < 0.005). The majority of consultations were for small bowel obstruction/ileus (n = 4, 17%), cholecystitis (n = 3, 13%) and to rule out ischemia (n = 2, 9%) In the era of modern critical care and cardiac surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

Management of complicated gallstones: results of an alternative approach to difficult cholecystectomies.

PubMed

Lirici, Marco Maria; Califano, Andrea

2010-10-01

Laparoscopic cholecystectomy (LC) is the gold standard treatment of gallstones. Nevertheless, the incidence of conversion and injuries to the biliary tract is still high in difficult cholecystectomies. In this study we sought to determine how using operative risk predictive scores (PSs) and the Nassar scale to grade the difficulty of LC would optimize the perioperative management of complicated gallstone patients. We also evaluated whether the "fundus-first" approach to LC combined with ultrasonic dissection minimizes the risk of conversion and biliary injury in difficult cholecystectomies, and avoids routine intraoperative cholangiography. A prospective non-randomized study was carried out from 2005 to 2007 including 237 patients referred for gallbladder diseases. All patients were evaluated using an operative risk PS. The LC grade of difficulty was assessed according to Nassar. Diagnostic accuracy, sensitivity, and specificity of PS were calculated. LC in difficult cases was accomplished with a fundus-first approach. Outcome measures included: Conversion rate, bile duct (BD) injury rate, and postoperative complications according to Clavien. In 178 out of 237 patients, a higher risk of conversion and complication was predicted. In 146 out of these 178 cases, intra-operative grading confirmed the difficulty of the procedure. The PS diagnostic accuracy was 0.865, sensitivity was 100%, and specificity 65%. Positive predictive value and negative predictive value were 0.82 and 1, respectively. Conversion rate was 2.7%. Mean operating time and postoperative length of hospital stay were 75 minutes and 3.5 days. Intra-operative cholangiography was necessary in five cases, and one intraoperative biliary complication occurred with an uneventful postoperative course. Overall, postoperative complications were 2.7% with a mortality rate of 0.68% (1 myocardial infarction). Fundus-first LC by ultrasonic dissection is safe and minimizes the risk of conversion and biliary injuries in difficult cases. Difficult cholecystectomies may be predicted preoperatively; in these cases the fundus-first approach and ultrasound dissection may be advised.

The economic burden of gallstone lithotripsy. Will cost determine its fate?

1991-01-01

Gallstone lithotripsy (LITHO) was performed on 52 patients who underwent 107 procedures. Two hundred sixty-seven gallstone patients were screened and 215 (81%) were excluded. Excessive stone burden and nonvisualization by oral cholecystogram (OCG) were the most common reasons for exclusion. The hospital course of 100 excluded patients who later underwent elective cholecystectomy was evaluated for length of hospital stay (2.3 days) and total cost of treatment ($3685.00). Successful fragmentation to less than 5 mm was achieved in 43 LITHO patients (83%). Five LITHO patients (10%) required conversion to operative management. Complications of LITHO included acute cholecystitis (1 of 52 patients) and biliary colic (17 of 52 patients, or 33%). Multiple procedures in one patient were common. Costs for LITHO were calculated in two ways: first the individual cost for each of the 52 candidates; second the cost for successful LITHO was calculated by excluding five patients who required operation as well as five patients (10%) who are predicted failures of LITHO. Including the preoperative evaluation, treatment, recovery room, and follow-up, the individual LITHO cost for 52 patients was $8275.00. If the same total expenditure is calculated after excluding patients who required operation and those predicted to fail, the cost per 'successful' LITHO procedure was $10,245. The cost of 1 year of bile acid therapy is $1949.00 or $2413.00 per 'successful' procedure. Follow-up costs were $1232.00 per patient or $1525.00 per 'successful' procedure. The added LITHO cost incurred by screening eventual noncandidates was $904.00 per successful procedure. The sum of these individual costs was $15,087.00 per success, as compared to $3685.00 for cholecystectomy. No allowance was made for cost of stone recurrence. Lithotripsy costs appear to be sufficiently high to render the procedure unlikely to emerge as the treatment of choice. PMID:2039296

Gallstone lithotripsy (LITHO) was performed on 52 patients who underwent 107 procedures. Two hundred sixty-seven gallstone patients were screened and 215 (81%) were excluded. Excessive stone burden and nonvisualization by oral cholecystogram (OCG) were the most common reasons for exclusion. The hospital course of 100 excluded patients who later underwent elective cholecystectomy was evaluated for length of hospital stay (2.3 days) and total cost of treatment ($3685.00).

Gallstones (GS) in south India (SI) are predominantly pure pigment or mixed, while in North India (NI), these are either pure cholesterol or mixed. While cholesterol rich gallbladder (GB) bile predicts cholesterol GS, constituent of bile in primary pigment GS is not known. We compared the composition of GB bile from healthy liver donors and patients with GS from north and south India. Gallbladder bile from healthy liver donors from north (10) and south India (8) served as controls. Cases were patients from north (21) and south India (17) who underwent cholecystectomy for GS disease. Gallbladder bile from both cases and controls was analyzed for cholesterol, lecithin (phospholipid), and bile salts. Gallstones were classified as cholesterol, mixed, and pigment based on morphology and biochemical analysis. The median cholesterol concentration in control bile from north was significantly high compared to south (p<0.001) with no difference in lecithin and bile salts (p NS). Except for one sample each from north and south, the cholesterol solubility of controls was within the critical micellar zone. Mixed GS were most frequent in north India (61.9 %) while pigment GS dominated in south (61.9 %). The median cholesterol concentration in bile samples of cholecystectomy patients from north India was significantly high GS (p < 0.00001) with significant lowering of bile salts and lecithin (p < 0.00001). In south India, patients with mixed GS had high cholesterol content in bile compared to controls and patients with pigment GS; bile in latter had significantly higher concentration of bile salt compared to controls and mixed GS. The ternary plot confirmed the composition of GB bile from north and south India. Gallbladder bile in controls and patients with GS from north India had significantly high cholesterol concentration. In south India, patients with mixed GS had cholesterol rich bile while pigment GS had higher concentrations of bile salts.

Also, to evaluate the safety of concomitant cholecistectomy. Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old.

In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the same prevalence of cholelithiasis. Gallstones occurred more in GERD patients without Barrett's esophagus. Simultaneous laparoscopic cholecystectomy was proved safe.

Sickle cell disease causes chronic and recurrent hemolysis which is a recognized risk factor for cholelithiasis. This complication occurs in 50% of adults with sickle cell disease. Surgery is the consensual therapy for symptomatic patients, but the surgical approach is still controversial in asymptomatic individuals. To determine the frequency and to describe and discuss the outcome of children with sickle cell disease complicated with gallstones followed up at a tertiary pediatric hematology center. In a retrospective and descriptive study, 225 charts were reviewed and data regarding patient outcome were recorded. The prevalence of cholelithiasis was 45% and half the patients were asymptomatic. The mean age at the time of diagnosis of cholelithiasis and surgical treatment was 12.5 years (standard deviation = 5) and 14 years (standard deviation = 5.4), respectively. The prevalence of cholelithiasis was higher in patients with SS homozygous and Sb heterozygous thalassemia when compared to patients with sickle cell disease. In 50% of symptomatic patients, recurrent abdominal pain was the single or predominant symptom. Thirty-nine of 44 patients submitted to surgery reported symptom relief after the surgical procedure. Asymptomatic individuals who did not undergo surgical treatment were followed up for 7 years (standard deviation = 4.8), and none of them presented complications related to cholelithiasis during this period. The frequency of cholelithiasis in the study population was 45%. One-third of the patients were diagnosed before 10 years of age. Patients with the SS homozygous or Sb heterozygous phenotype were at a higher risk for the development of cholelithiasis than patients with sickle cell disease. About 50% of patients with gallstones were asymptomatic, the most of them did not undergo surgery and did not present complications during a 7-year follow-up period. Cholecystectomy must be considered in symptomatic patients. In asymptomatic patients, conservative management seems to be the better choice.

In hepatocytes and enterocytes sterol uptake and secretion is mediated by Niemann-Pick C1-like 1 (NPC1L1) and ATP-binding cassette (ABC)G5/8 proteins, respectively. Whereas serum levels of phytosterols represent surrogate markers for intestinal cholesterol absorption, cholesterol precursors reflect cholesterol biosynthesis. Here we compare serum and biliary sterol levels in ethnically different populations of patients with gallstone disease (GSD) and stone-free controls to identify differences in cholesterol transport and synthesis between these groups. In this case-control study four cohorts were analyzed: 112 German patients with GSD and 152 controls; two distinct Chilean ethnic groups: Hispanics (100 GSD, 100 controls), and Amerindians (20 GSD, 20 controls); additionally an 8-year follow-up of 70 Hispanics was performed. Serum sterols were measured by gas chromatography / mass spectrometry. Gallbladder bile sterol levels were analyzed in cholesterol GSD and controls. Common ABCG5/8 variants were genotyped. Comparison of serum sterols showed lower levels of phytosterols and higher levels of cholesterol precursors in GSD patients than in controls. The ratios of phytosterols to cholesterol precursors were lower in GSD patients, whereas biliary phytosterol and cholesterol concentrations were elevated as compared with controls. In the follow-up study, serum phytosterol levels were significantly lower even before GSD was detectable by ultrasound. An ethnic gradient in the ratios of phytosterols to cholesterol precursors was apparent (Germans > Hispanics > Amerindians). ABCG5/8 variants did not fully explain the sterol metabolic trait of GSD in any of the cohorts. Individuals predisposed to GSD display increased biliary output of cholesterol in the setting of relatively low intestinal cholesterol absorption, indicating enhanced whole-body sterol clearance. This metabolic trait precedes gallstone formation and is a feature of ethnic groups at higher risk of cholesterol GSD. Copyright © 2012 American Association for the Study of Liver Diseases.

Heme oxygenase (HO-1) protects against inflammation. In this study, we investigated the protective function of hemin-induced HO-1 against lipopolysaccharide (LPS)-induced ileus. Rats received LPS intraperitoneally 24 h after intraperitoneal hemin pretreatment or placebo. We also injected zinc protoporphyrin (ZnPP, 3rd group), an inhibitor of HO-1, intraperitoneally 2 h before LPS administration. To assess intestinal muscle function, we examined muscularis strip contractility in an organ bath and measured gastrointestinal transit in vivo. We investigated inflammation within the muscularis using polymerase chain reaction (interleukin [IL]-6, inducible nitric oxide synthase (iNOS), HO-1 and IL-10) 6 and 24 h after LPS. Hemin significantly improved in vitro intestinal muscularis contractility (P < 0.001). In addition, hemin prevented LPS-induced dysmotility in vivo (gastrointestinal transit, geometric center: 8.39 ± 0.33 versus 5.68 ± 0.44; P < 0.001). In Zinc protoporphyrin (ZnPP)-treated animals, both parameters were significantly decreased compared with the hemin group. Messenger RNA expression demonstrated a significant reduction in IL-6 (6 h, hemin: 127.6 ± 36.7 versus LPS: 14,431 ± 5407; 24 h: 1.58 ± 0.39 versus 11.15 ± 2.59; P < 0.01) and iNOS (6 h: 2516 ± 985 versus 50,771 ± 13,321; 24 h: 55.11 ± 10.55 versus 257.1 ± 43.18; P < 0.001) in hemin-treated animals. Anti-inflammatory HO-1 messenger RNA levels (6 h, hemin: 116.3 ± 18.55 versus LPS: 26.02 ± 3.64; 24 h: 18.46 ± 2.69 versus 2.80 ± 0.32; P < 0.001) were increased. There was no significant difference in IL-10 levels at 6 and 24 h. ZnPP reversed the anti-inflammatory hemin effects. Hemin induction of HO-1 diminishes LPS-induced sepsis. Heme oxygenase-1 has a central role in preventing sepsis-induced ileus. This benefit is reversed by HO-1 inhibition with ZnPP. Copyright © 2012 Elsevier Inc. All rights reserved.

Previous studies failed to demonstrate a genetic predisposition to liver disease in cystic fibrosis. In order to characterize patients with cirrhosis defined on the basis of either hepatosplenomegaly, portal hypertension or liver biopsy, we analyzed a total number of 110 cirrhotic CF patients from different CF centers in France. Of them, 71 are males, which is not different from the overall CF french population. All but 2 are pancreatic insufficient. A history of meconium ileus {plus_minus} meconium ileus equivalent seems to be a risk factor for cirrhosis since these complications are present in 29% of the cirrhotic patients vs. 19%more » in the non-cirrhotic population (p = 0.03). This confirms our previous data in a postmortem study. Genotype analysis was performed in all the patients. {Delta}F508 represents 70% of the identified mutations with a higher proportion of {Delta}F508 +/+ in the cirrhotic than in the non-cirrhotic population (52% vs. 42%, p=0.003), 35% {Delta}F508 +/- vs. 42% and 13% {Delta}F508 -/- vs. 16%. Sixty percent of the other mutations associated with cirrhosis are identified, usually in {Delta}F508 +/- and include 1303 N-K, 542 G-X, 1078 del T, 1282 W-X, 1313 Q-X, 827 E-X, 1061 G-R, 1301 N-H, 14 K-X, 1717-1 G-A, 1918 delGC, 2183 A-G, 2184 delA, 405+1 G-A, 507 {Delta}l, 574 delA, 621+1 G-T, 85 G-E and 1303 N-K/other, 227 L-R/other. None of the cirrhotic patients bear one of the dominant missense mutations regarded as mild with respect to pancreatic function (117 R-H, 334 R-W, 347 R-P, 455 A-E, 574 P-H) or both the {Delta}F508 and the 5512 G-A mutations associated with a decreased risk of meconium ileus. Cirrhosis could thus be linked to the presence of 2 of the severe mutations of the CF gene associated with pancreatic insufficiency.« less

The utility of early endoscopic retrograde cholangiopancreatography (ERCP) ± endoscopic sphincterotomy (ES) in the treatment of gallstone pancreatitis (GSP) is still contentious. The aim was to conduct a meta-analysis of randomized controlled trials (RCTs) investigating the treatment of GSP by early ERCP ± ES versus conservative management and analyzing the patient outcomes. A search of Medline, Embase, Science Citation Index, Current Contents, PubMed, and the Cochrane Database of Systematic Reviews identified all RCTs comparing early ERCP to conservative management in GSP published between January 1970 and January 2014. Search terms included "Endoscopic retrograde cholangiopancreatography (ERCP)"; "Endoscopic sphincterotomy"; "Gallstones"; "Bile duct stones"; "Gallstone pancreatitis"; "Biliary pancreatitis"; "Randomize/Randomised controlled trials"; "Conservative management/treatment"; "Human"; "English." Only prospective RCTs comparing early intervention (ie, between 24 and 72 h) with ERCP ± ES versus conservative management in GSP were included. Data extraction and critical appraisal was carried out independently by 2 authors (M.J.B. and M.A.M.) using predefined data fields. Variables analyzed included severity of pancreatitis (mild or severe), overall mortality, overall complications which included pseudocyst formation, organ failure (renal, respiratory, and cardiac), abnormal coagulation, biliary sepsis, and development of pancreatic abscess/phlegmon. The quality of RCTs was assessed using Jadad's scoring system. Random-effects model was used to calculate the outcomes of both binary and continuous data. Heterogeneity among the outcome variables of these trials was determined by the Cochran Q statistic and I2 index. The meta-analysis was prepared in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Eleven RCTs consisting of 1314 patients (conservative management=662, ERCP=652) were analyzed. There was a near significant decrease in mortality for ERCP group compared with conservatively managed patients with severe pancreatitis [odds ratio (OR) 0.45; 95% confidence interval (CI), 0.19, 1.09; P=0.08]. In patients with mild pancreatitis, mortality results were comparable for both groups (OR 0.66; 95% CI, 0.02, 28.75; P=0.83). Overall complications were significantly reduced in the ERCP group in severe pancreatic patients (OR 0.32; 95% CI, 0.17, 0.61; P=0.00). In those with mild disease, a strong trend to decreased complications in the ERCP group was seen, however, this was not significant (OR 0.67; 95% CI, 0.43, 1.03; P=0.06). This meta-analysis demonstrates a significant decrease in complications in patients with severe GSP managed with early ERCP/ES compared with conservative management. As far as the mortality is concerned, no significant decrease was observed in mortality even in severe GSP patients treated with early ERCP/ES.

Interplay between inflammation, immune system and neuronal pathways: Effect on gastrointestinal motility

PubMed Central

De Winter, Benedicte Y; De Man, Joris G

2010-01-01

Sepsis is a systemic inflammatory response representing the leading cause of death in critically ill patients, mostly due to multiple organ failure. The gastrointestinal tract plays a pivotal role in the pathogenesis of sepsis-induced multiple organ failure through intestinal barrier dysfunction, bacterial translocation and ileus. In this review we address the role of the gastrointestinal tract, the mediators, cell types and transduction pathways involved, based on experimental data obtained from models of inflammation-induced ileus and (preliminary) clinical data. The complex interplay within the gastrointestinal wall between mast cells, residential macrophages and glial cells on the one hand, and neurons and smooth muscle cells on the other hand, involves intracellular signaling pathways, Toll-like receptors and a plethora of neuroactive substances such as nitric oxide, prostaglandins, cytokines, chemokines, growth factors, tryptases and hormones. Multidirectional signaling between the different components in the gastrointestinal wall, the spinal cord and central nervous system impacts inflammation and its consequences. We propose that novel therapeutic strategies should target inflammation on the one hand and gastrointestinal motility, gastrointestinal sensitivity and even pain signaling on the other hand, for instance by impeding afferent neuronal signaling, by activation of the vagal anti-inflammatory pathway or by the use of pharmacological agents such as ghrelin and ghrelin agonists or drugs interfering with the endocannabinoid system.

Paralytic ileus after laparoscopic-assisted surgery often occurs. We investigated whether daikenchuto (DKT), a traditional Japanese herbal medicine, improves intestinal motility in patients undergoing laparoscopic-assisted colectomy for colon cancer. Fifty-four patients who underwent colectomy at Iwate Medical University Hospital between October 2010 and March 2012 were randomized to either the DKT group (7.5 g/day, p.o.) or the control group (lactobacillus preparation, 3g/day, p.o.). Primary endpoints included time to first flatus, bowel movement, and tolerance of diet after extubation. Secondary endpoints were WBC count, C-reactive protein (CRP) level, length of hospital stay, and postoperative ileus. Colonic transit time was measured using radiopaque markers and abdominal radiographs. Fifty-one patients (DKT, 26 vs. control, 25) were included in the per-protocol analysis. The DKT group had significantly faster time until first flatus (67.5 +/- 13.6h vs. 77.9 +/- 11.8h, P < 0.01) and bowel movement (82.9 +/- 17.8h vs. 99.5 +/- 18.9h, P < 0.01) and colonic transit time (91.9 +/- 19.8h vs. 115.2 +/- 12.8 h, P < 0.05). There were no significant intergroup differences in secondary endpoints and adverse events. DKT accelerates colonic motility in patients undergoing laparoscopic-assisted colectomy for colon cancer.

Developmental abnormalities of liver including ectopic liver tissue (ELT) are rare conditions. Few cases presenting ELT have been reported in literature till now. Even though the most common area seen is gallbladder, it is detected both abdominal and thoracic sites. There is a relationship between HCC and ectopic liver that necessitates the removal. A 51-year-old female was hospitalized because of abdominal pain. Gallstone and bile duct dilatation were determined during ultrasonographic (USG) evaluation. The patient was operated for cholecystectomy following a successful endoscopic retrograde cholangiopancreatography (ERCP). During operation, a mass located on gallbladder with its unique vascular support was identified and resected together with gallbladder. The mass had a separate vascular stalk arising from liver parenchyma substance and it was clipped with laparoscopic staples. The histopathological examination revealed that the mass adherent to gallbladder was ectopic liver confirming the intraoperative observation. The postoperative course of patient was uneventfull and she was discharged at the second day after the operation. Ectopic liver tissue is incidentally found both in abdominal and thoracic cavity. ELT can rarely be diagnosed before surgical procedures or autopsies. It can be overlooked easily by radiological techniques. Although it does not usually produce any symptom clinically, it can rarely result in serious complications such as bleeding, pyloric and portal vein obstruction. ELT also has the capacity of malignant transformation to hepatocellular carcinoma that makes it essential to be removed. Although ELT is rarely seen, it should be removed when recognized in order to prevent the complications and malignant transformation. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Abdominal Pain After Roux-En-Y Gastric Bypass for Morbid Obesity.

Mala, Tom; Høgestøl, Ingvild

2018-05-01

Roux-en-Y gastric bypass is widely used as treatment of morbid obesity. Weight loss, effects on obesity-related co-morbidities and quality of life are well documented post Roux-en-Y gastric bypass. Other outcome measures are less well studied. This review explores aspects of prevalence, diagnostic evaluations, etiology, and treatment of abdominal pain specific to Roux-en-Y gastric bypass. The review is based on PubMed searches and clinical experience with Roux-en-Y gastric bypass. Symptoms in the early postoperative phase (<30 days) were not included. Based on limited evidence, up to about 30% of the patients may perceive recurrent abdominal pain post Roux-en-Y gastric bypass in the long term. A substantial subset of patients will need health-care evaluation for acute abdominal pain and hospital admission. The etiology of abdominal pain is heterogeneous and includes gallstone-related disease, intestinal obstruction, anastomotic ulcerations and strictures, intestinal dysmotility, dysfunctional eating, and food intolerance. Surgical treatment and guidance on diet and eating habits may allow symptom relief. The cause of pain remains undefined for a subset of patients. Impact of abdominal pain post Roux-en-Y gastric bypass on the perception of well-being, quality of life, and patient satisfaction with the procedure needs to be further evaluated and may be influenced by complex interactions between new symptoms post Roux-en-Y gastric bypass and relief of pre-existing symptoms. Abdominal pain should be part of follow-up consultations post Roux-en-Y gastric bypass. Future studies should focus on combined evaluations before and after surgery to enlighten potential casual relationships between abdominal pain and Roux-en-Y gastric bypass.

AIM: To investigate the safety and feasibility of our original single-incision laparoscopic cholecystectomy (SILC) for acute inflamed gallbladder (AIG). METHODS: One hundred and ten consecutive patients underwent original SILC for gallbladder disease without any selection criteria and 15 and 11 of these were diagnosed with acute cholecystitis and acute gallstone cholangitis, respectively. A retrospective review was performed not only between SILC for AIG and non-AIG, but also between SILC for AIG and traditional laparoscopic cholecystectomy (TLC) for AIG in the same period. RESULTS: Comparison between SILC for AIG and non-AIG revealed that the operative time was longer in SILC for AIG (97.5 min vs 85.0 min, P = 0.03). The open conversion rate (2/26 vs 2/84, P = 0.24) and complication rate (1/26 vs 3/84, P = 1.00) showed no differences, but a need for additional trocars was more frequent in SILC for AIG (5/24 vs 3/82, P = 0.01). Comparison between SILC for AIG and TLC for AIG revealed no differences based on statistical analysis. CONCLUSION: Our original SILC technique was adequately safe and feasible for the treatment of acute cholecystitis and acute gallstone cholangitis. PMID:22408354

Anti-cholelithogenic potential of dietary spices and their bioactives.

Dietary hypocholesterolemic spices-curcumin (active compound of turmeric (Curcuma longa)) and capsaicin (active compound of red pepper (Capsicum annuum)), the active principles of spices-turmeric (Curcuma longa) and red pepper (Capsicum annuum), fenugreek (Trigonella foenum-graecum) seeds, garlic (Allium sativum), and onion (Allium cepa) are documented to have anti-cholelithogenic property in animal model. These spices prevent the induction of cholesterol gallstones by lithogenic high cholesterol diet and also regress the pre-established cholesterol gallstones, by virtue of their hypolipidemic potential. The antilithogenic influence of these spices is primarily attributable to their hypocholesterolemic effect. Increased cholesterol saturation index, cholesterol:phospholipid ratio and cholesterol:bile acid ratio in the bile caused by the lithogenic diet was countered by these spices. The antilithogenicity of these hypocholesterolemic spices was considered to be due also to their influence on biliary proteins that have pro-nucleating activity and anti-nucleating activity. Investigations on the involvement of biliary proteins in cholesterol crystal nucleation revealed that in an in vitro bile model, low molecular weight biliary proteins of the lithogenic diet fed animals have a pro-nucleating activity. On the contrary, low molecular weight biliary proteins of the animals fed hypocholesterolemic spices along with lithogenic diet showed a potent anti-nucleating activity.

The mechanism of enterohepatic circulation in the formation of gallstone disease.

PubMed

Cai, Jian-Shan; Chen, Jin-Hong

Bile acids entering into enterohepatic circulating are primary acids synthesized from cholesterol in hepatocyte. They are secreted actively across canalicular membrane and carried in bile to gallbladder, where they are concentrated during digestion. About 95% BAs are actively taken up from the lumen of terminal ileum efficiently, leaving only approximately 5% (or approximately 0.5 g/d) in colon, and a fraction of bile acids are passively reabsorbed after a series of modifications in the human large intestine including deconjugation and oxidation of hydroxy groups. Bile salts hydrolysis and hydroxy group dehydrogenation reactions are performed by a broad spectrum of intestinal anaerobic bacteria. Next, hepatocyte reabsorbs bile acids from sinusoidal blood, which are carried to liver through portal vein via a series of transporters. Bile acids (BAs) transporters are critical for maintenance of the enterohepatic BAs circulation, where BAs exert their multiple physiological functions including stimulation of bile flow, intestinal absorption of lipophilic nutrients, solubilization, and excretion of cholesterol. Tight regulation of BA transporters via nuclear receptors (NRs) is necessary to maintain proper BA homeostasis. In conclusion, disturbances of enterohepatic circulation may account for pathogenesis of gallstones diseases, including BAs transporters and their regulatory NRs and the metabolism of intestinal bacterias, etc.

In laparoscopic prostatectomies, vesicourethral anastomotic leaks may result in significant morbidity because of the chemical and metabolic derangements created by urine within the peritoneal cavity. To date, minimal data are available on this problem. Herein we present our experience with urine leaks after RALP. Over a period of 24 months, 135 men underwent RALP. Any drainage creatinine greater than two times the serum creatinine was considered as an anastomotic leak. According to our criteria, 20% of the first 110 patients developed an anastomotic leak. The patients were analyzed in two groups, those with and without leaks. In the two groups, there was no statistically significant difference in age, height, weight, prostate volume and pre-op hemoglobin. The patients with leaks did have higher rate of prior abdominal surgery (50 vs. 36%), higher average pre-operative PSA values (7.6 vs. 6.1), higher rates of multiple biopsies (27 vs. 17%) and a higher average BMI (29.6 vs. 27.8). Intraoperative differences included an average of 30 min longer operative time and 66 cm(3) higher average EBL in patients with leaks. The transfusion rate was higher in the leak group at 18 vs. 1% in the no leak group. Recovery tended to be longer in patients with leaks, with hospital stays of an average of 3.6 days longer. The most common indication for prolonged hospitalization was ileus, which 55% of patients with leaks developed. Management included placing the catheter on mild traction, continuous antibiotics and taking the drain-off suction with caution to monitor the signs of a worsening ileus. In the last 25 patients, we revised our anastomotic technique. We now include posterior tailoring of the bladder neck prior to the vesicourethral anastomosis when the bladder neck is enlarged. This facilitates a water-tight anastomosis. Using this technique, we have yet to see the anastomotic leak. In RALPs, anastomotic leaks can lead to ileus formation and longer hospital stays. These leaks are associated with a higher average blood loss and transfusion rate. Management should focus on prevention. Since we have incorporated posterior bladder neck tailoring with the anastomosis, the problem has been markedly reduced.

Acute abdomen in mentally retarded patients: role of aerophagia. Report of nine cases.

1999-05-01

Between 1993 and 1996 nine mentally retarded patients presented because of an acute abdomen. All had the habit of aerophagia, diagnosed previously by a general practitioner. Massive distension of the bowel led to ileus, volvulus, and necrosis. After placement of a percutaneous endoscopic gastrostomy catheter or performing a gastrostomy during laparotomy with the intention to use as a desufflator, no recurrence of the signs and symptoms of an acute abdomen were observed.

Ghrelin and ghrelin mimetics stimulate appetite and enhance gastric motility. The present study investigates whether ipamorelin, a selective growth hormone secretagogue and agonist of the ghrelin receptor, would accelerate gastrointestinal transit and ameliorate the symptoms in a rodent model of postoperative ileus (POI). Fasted male rats were subjected to laparotomy and intestinal manipulation. At the end of surgery, a dye marker was infused in the proximal colon to evaluate postsurgical colonic transit time, which was the time to the first bowel movement. In addition, fecal pellet output, food intake, and body weight were monitored regularly for 48 h. Ipamorelin (0.01-1 mg/kg), growth hormone-releasing peptide (GHRP)-6 (20 microg/kg), or vehicle (saline) were administered via intravenous bolus infusion after a single dosing or a 2-day repetitive dosing regimen (four doses a day at 3-h intervals). Compared with the vehicle, a single dose of ipamorelin (1 mg/kg) or GHRP-6 (20 microg/kg) decreased the time to the first bowel movement but had no effect on cumulative fecal output, food intake, or body weight gain measured 48 h after the surgery. In contrast, repetitive dosing of ipamorelin (0.1 or 1 mg/kg) significantly increased the cumulative fecal pellet output, food intake, and body weight gain. The results suggest that postsurgical intravenous infusions of ipamorelin may ameliorate the symptoms in patients with POI.

This study aimed to assess the efficacy of daikenchuto (DKT), a commonly prescribed, traditional Japanese herbal medicine, on postoperative intestinal dysfunction after gastric cancer surgery. Patients with gastric cancer scheduled for a total gastrectomy were randomly assigned before surgery to receive either no treatment (n = 40; control group) or DKT (7.5 g/day, t.i.d.) for 3 months (n = 41) postoperatively. We examined gastrointestinal motility, stool attributes, the quantity of bowel gas, the quality of life, and the incidence of postoperative ileus. During the hospital stay, significant differences were observed between the DKT group and controls in the number of stools per day (1.1 ± 0.6 vs 0.8 ± 0.4, respectively; P = 0.037) and stool consistencies (Bristol scale ratings were 3.7 ± 0.8 vs 3.1 ± 0.8, respectively; P = 0.041). The DKT group showed significant reductions in gas volume scores, calculated from abdominal radiographs, at 7 days, 1 month, and 3 months after surgery. The groups did not show significant differences in quality of life scores (based on the Gastrointestinal Symptom Rating Scale) or in the incidence of postoperative ileus. DKT improved bowel movements, stool properties, and bowel gas. These results suggested that DKT promoted early postoperative bowel functions after total gastrectomy.

BACKGROUND This study aimed to determine the effects of use of a local hemostatic gelatin sponge (GS) on postoperative morbidity in patients undergoing cesarean section (CS). MATERIAL AND METHODS The records of 318 patients who underwent CS surgery were retrospectively evaluated. Group 1 consisted of 59 patients with gelatin sponge (GS) applied, and Group 2 consisted of 259 patients with no GS applied. The groups were compared for time to the first flatus, nausea and vomiting, requirement for anti-emetic drugs, development of postoperative ileus, and the length of hospitalization. RESULTS The patients in Group 1 and Group 2 were statistically similar in mean age, gravida, parity, and body mass index (BMI) (p=0.352, p=0.275, p=0.458, and p=0.814, respectively). No significant difference was determined in the number of patients with nausea, vomiting, anti-emetic drug use, febrile morbidity, and postoperative ileus (p=0.063, p=0.436, p=328, p=0.632, and p=0.179, respectively). Time to the first flatus and length of hospitalization were significantly longer in Group 2 (p<0.001 and p<0.001, respectively). CONCLUSIONS Delay in recovery of bowel motility may be due to the local hypersensitivity reaction caused by GS and/or dislocation of this local hemostat. Women who receive gelatin sponge treatment during CS should be monitored closely for the recovery of postoperative intestinal motility.

Background: Enhanced gallbladder concentrating function is an important factor for the pathogenesis of cholesterol gallstone disease (CGD), but the mechanism is unknown. Potential candidates for regulation of gallbladder ion absorption are suggested to be Na+/H+ exchanger isoform 3 (NHE3). In this study, we investigated the expression and subcellular localization of NHE3 in both acalculous and calculous human gallbladders. Methods: Adult human gallbladder tissue was obtained from 23 patients (7 men, 16 women) who had undergone cholecystectomy. The patients were divided into two groups: Group A (acalculous group) and Group B (calculous group). Gene expression of NHE3 was quantitatively estimated by real-time PCR. Protein expression was studied by Western blotting assays. Furthermore, expression of immunoreactive NHE3 was investigated by immunohistochemistry. Results: There was no significant difference in the NHE3 mRNA expression between calculous and acalculous human gallbladders. NHE3 protein expression in gallbladders from patients with cholelithiasis is increased compared to those without gallstones. Immunohistochemistry studies prove that NHE3 is located both on the apical plasma membrane and in the intracellular pool in human GBECs. Conclusions: NHE3 may play a role in the pathogenesis of human CGD. Additional studies are required to further delineate the underlying mechanisms. PMID:25674247

Biliary lithotripsy can be enhanced with proper ultrasound probe position.

We have demonstrated in our in vitro system that an extracorporeal lithotripter utilizing a movable ultrasound probe can fragment gallstones more effectively when the ultrasound probe is not partially blocking shock waves. Using a pressure transducer we measured the pressures in the focal volume of a Wolf Piezolith 2300 lithotripter with the ultrasound probe fully extended and fully retracted. We also chose 12 pairs of twin gallstones, each taken from the same gallbladder. One stone from each pair was subjected to shock waves while the ultrasound probe was fully extended and the other treated while the probe was fully retracted. Shock wave pressures (which are converted to a measurable voltage output by our transducer) were clearly lower when the ultrasound probe was extended (5.45 volts; SEM = 0.10 volts) as compared to when the ultrasound scanner was retracted (6.7 volts: SEM = 0.08 volts). Significantly more shock waves were required to completely fragment stones when the ultrasound scanner was extended than when it was retracted (p = 0.01 using the nonparametric Wilcoxon's signed rank test). These results show that, in the lithotripter tested, an extended in-line ultrasound scanner can partially block shock waves. Retraction of an extendible ultrasound probe may enhance stone fragmentation when operating at the highest shock wave intensity.

Gallbladder polyps are seen on as many as 7% of gallbladder ultrasonographic images. The differential diagnosis for a polypoid gallbladder mass is wide and includes pseudotumors, as well as benign and malignant tumors. Tumefactive sludge may be mistaken for a gallbladder polyp. Pseudotumors include cholesterol polyps, adenomyomatosis, and inflammatory polyps, and they occur in that order of frequency. The most common benign and malignant tumors are adenomas and primary adenocarcinoma, respectively. Polyp size, shape, and other ancillary imaging findings, such as a wide base, wall thickening, and coexistent gallstones, are pertinent items to report when gallbladder polyps are discovered. These findings, as well as patient age and risk factors for gallbladder cancer, guide clinical decision making. Symptomatic polyps without other cause for symptoms, an age over 50 years, and the presence of gallstones are generally considered indications for cholecystectomy. Incidentally noted pedunculated polyps smaller than 5 mm generally do not require follow-up. Polyps that are 6-10 mm require follow-up, although neither the frequency nor the length of follow-up has been established. Polyps that are larger than 10 mm are typically excised, although lower size thresholds for cholecystectomy may be considered for patients with increased risk for gallbladder carcinoma, such as patients with primary sclerosing cholangitis.

Gallstones consist of calcium salts and cholesterol crystals, arrayed on a matrix of gallbladder mucin (GBM), and regulatory proteins like calcium-binding protein (CBP). To determine if interactions between CBP and GBM follow a biomineralization scheme, their mutual binding and effects on CaHPO4 precipitation were studied. Binding of CBP to GBM was assessed by inhibition of the fluorescence of the complex of GBM with bis-1,8-anilinonaphthalene sulfonic acid (bis-ANS). The effects of the proteins on precipitation of CaHPO4 were assessed by nephelometry and gravimetry. Precipitates were analyzed for calcium, phosphate, and protein. CBP and bis-ANS competitively displaced each other from 30 binding sites on mucin, with a 1:1 stoichiometry and similar affinity. The rate of precipitation of CaHPO4 was retarded by mucin and CBP. Precipitate mass was unaffected by GBM alone but decreased with the addition of CBP. Complexing CBP with GBM abolished or moderated this latter effect, altered precipitate morphology, and changed the stoichiometric ratios of Ca to PO4 in the precipitates from 1:1 to 3:2. Mucin and CBP were incorporated into the precipitates. These studies suggest that the formation of calcium-containing gallstones is a biomineralization process regulated by both GBM and CBP.

The case for aflatoxins in the causal chain of gallbladder cancer.

Chronic aflatoxin exposure has long been related to hepatocellular carcinoma (HCC). Recently, its association with gallbladder cancer (GBC) was postulated. Here we present the data supporting this hypothesis in Chile, the country with the highest GBC mortality worldwide with age-standardized mortality rates (ASMR) of 10.3 in women and 5.04 in men. The highest GBC rates occur in Southern Chile (ASMR=18), characterized by: high Amerindian ancestry, associated with high bile acid synthesis and gallstones; high poverty and high cereal agriculture, both associated with aflatoxin exposure. Aflatoxins have been detected in imported and locally grown foods items. We estimated population dietary exposure ranging from 0.25 to 35.0 ng/kg-body weight/day. The only report on human exposure in Chile found significantly more aflatoxin biomarkers in GBC than in controls (Odds Ratio=13.0). The hypothesis of aflatoxin-GBC causal link in the Chilean population is supported by: genetically-determined rapid cholesterol excretion and high gallstones prevalence (49.4%); low prevalence of HCC (ASMR=4.9) and low HBV infection (0.15%) the main co-factor of aflatoxins in HCC risk. If the association between aflatoxins and GBC were confirmed, public health interventions based on food regulation could have a substantial public health impact. Copyright © 2015 Elsevier Ltd.

To test the hypothesis that progesterone alters sphincter of Oddi and gallbladder function and, therefore, bile flow dynamics. Although the effects of progesterone on the biliary tract have been implicated in the increased incidence of gallstones among women, the specific effects of prolonged elevation of progesterone levels, such as occurs with contraceptive progesterone implants and during pregnancy, on the sphincter of Oddi and biliary flow dynamics are still incompletely understood. Adult female prairie dogs were randomly assigned to receive subcutaneous implants containing either progesterone or inactive pellet matrix only. Hepatic bile partitioning and gallbladder emptying were determined 14 days later using 99mTc-Mebrofenin cholescintigraphy. Significantly less hepatic bile partitioned into the gallbladder in progesterone-treated than in control animals. The gallbladder ejection fraction was significantly reduced from 73+/-6% in controls to 59+/-3% in the progesterone-treated animals. The rate of gallbladder emptying was significantly reduced from 3.6+/-0.3%/minute to 2.9+/-0.1%/minute. Progesterone administered as subcutaneous implants alters partitioning of hepatic bile between gallbladder and small intestine and, therefore, gallbladder filling. Progesterone also significantly impairs gallbladder emptying in response to cholecystokinin. The effects of progesterone on the sphincter of Oddi and the gallbladder may contribute to the greater prevalence of gallstones and biliary motility disorders among women.

To study the c-Kit expression in the gallbladder of cholesterol lithogenic guinea pig model and the effect of Artemisia capillaris Thunb on interstitial cells of Cajal (ICCs). A total of 45 guinea pigs were randomly assigned into three groups: the control group (guinea pigs fed a standard diet, normal group); the model group (guinea pigs fed a cholesterol gallstone-inducing diet); and the Chinese medicine group (guinea pigs fed the cholesterol gallstone-inducing diet and treated with A. capillaris through intragastric administration, therapy group). Each group had 15 guinea pigs. The gallbladders of the guinea pigs were harvested after 8 weeks. C-Kit expression was detected using an immunohistochemistry staining, real-time PCR, and Western blot analyses. The effect of A. capillaris on ICCs was evaluated by muscle strip contraction experiments. C-Kit expression significantly decreased in the gallbladder of model group, but increased in the Chinese medicine group. The Contractility of guinea pig gallbladder muscle strip significantly improved in the Chinese medicine group. Our results indicated that A. capillaris improves gallbladder impairment by up-regulating c-Kit expression, and it also can improve the contractile response of in vitro guinea pig gallbladder muscle strips.

Plasma shield lasertripsy: in vitro studies.

1989-10-01

A technique for safer and more effective pulsed laser lithotripsy of urinary and biliary calculi was investigated in vitro. The technique involves enclosing the distal end of the laser delivery fiber in a "plasma shield." The plasma shield is a specially designed metal cap that serves to transfer the laser-induced mechanical impulse to the calculus while shielding surrounding tissue from direct laser exposure and thermal radiation. The metal cap also offers the advantage of effectively blunting the sharp fiber tip and improving its visualization under fluoroscopy. Plasma shield lithotripsy using a 200 micron quartz fiber inserted into a section of a modified 0.034 in. diameter stainless steel guide wire was tested in vitro on a variety of calculi and compared with results obtained using a 200 micron laser fiber applied directly. Calculi tested included cystine, struvite and calcium oxalate dihydrate urinary stones and pigmented cholesterol gallstones. The laser source was a flashlamp-pumped dye laser producing pulses of 1.2 microsecond duration and operated at a wavelength of 504 nm and pulse repetition frequency of 5 Hz. The results show that plasma shield lasertripsy is as effective as direct lasertripsy for fragmenting gallstones, struvite and calcium oxalate dihydrate calculi, is potentially safer, and can fragment cystine calculi which the pulsed dye laser applied directly cannot.

For radical cystectomy, historical practice trends have favored the use of preoperative bowel preparations to reduce complications, including surgical site infections, ileus, and anastomotic leaks. However, emerging data has questioned this practice. Postoperative cystectomy care also remains in flux, as new pharmacologic agents that may potentiate earlier return of bowel function are studied. We review the current literature with regards to preoperative and postoperative cystectomy bowel management.

Acute abdominal pain in patients with lassa fever: Radiological assessment and diagnostic challenges

PubMed Central

Eze, Kenneth C.; Salami, Taofeek A.; Kpolugbo, James U.

2014-01-01

Background: To highlight the problems of diagnosis and management of acute abdomen in patients with lassa fever. And to also highlight the need for high index of suspicion of lassa fever in patients presenting with acute abdominal pain in order to avoid surgical intervention with unfavourable prognosis and nosocomial transmission of infections, especially in Lassa fever-endemic regions. Materials and Methods: A review of experiences of the authors in the management of lassa fever over a 4-year period (2004-2008). Literature on lassa fever, available in the internet and other local sources, was studied in November 2010 and reviewed. Results: Normal plain chest radiographic picture can change rapidly due to pulmonary oedema, pulmonary haemorrhage and acute respiratory distress syndrome. Plain abdominal radiograph may show dilated bowels with signs of paralytic ileus or dynamic intestinal obstruction due to bowel wall haemorrhage or inflamed and enlarged Peyer's patches. Ultrasound may show free intra-peritoneal fluid due to peritonitis and intra-peritoneal haemorrhage. Bleeding into the gall bladder wall may erroneously suggest infective cholecystitis. Pericardial effusion with or without pericarditis causing abdominal pain may be seen using echocardiography. High index of suspicion, antibody testing for lassa fever and viral isolation in a reference laboratory are critical for accurate diagnosis. Conclusion: Patients from lassa fever-endemic regions may present with features that suggest acute abdomen. Radiological studies may show findings that suggest acute abdomen but these should be interpreted in the light of the general clinical condition of the patient. It is necessary to know that acute abdominal pain and vomiting in lassa fever-endemic areas could be caused by lassa fever, which is a medical condition. Surgical option should be undertaken with restraint as it increases the morbidity, may worsen the prognosis and increase the risk of nosocomial transmission. PMID:25013248

Rationale The current standard surgical treatment for the cervix and uterine cancer is the radical hysterectomy (lymphadenohysterocolpectomy). This has the risk of intraoperative accidents and postoperative associated morbidity. Objective The purpose of this article is the evaluation and quantification of the associated complications in comparison to the postoperative morbidity which resulted after different types of radical hysterectomy. Methods and results Patients were divided according to the type of surgery performed as follows: for cervical cancer – group A- 37 classic radical hysterectomies Class III Piver - Rutledge -Smith ( PRS ), group B -208 modified radical hysterectomies Class II PRS and for uterine cancer- group C -79 extended hysterectomies with pelvic lymphadenectomy from which 17 patients with paraaortic lymphnode biopsy . All patients performed preoperative radiotherapy and 88 of them associated radiosensitization. Discussion Early complications were intra-abdominal bleeding ( 2.7% Class III PRS vs 0.48% Class II PRS), supra-aponeurotic hematoma ( 5.4% III vs 2.4% II) , dynamic ileus (2.7% III vs 0.96% II) and uro - genital fistulas (5.4% III vs 0.96% II).The late complications were the bladder dysfunction (21.6% III vs 16.35% II) , lower limb lymphedema (13.5% III vs 11.5% II), urethral strictures (10.8% III vs 4.8% II) , incisional hernias ( 8.1% III vs 7.2% II), persistent pelvic pain (18.91% III vs 7.7% II), bowel obstruction (5.4% III vs 1.4% II) and deterioration of sexual function (83.3% III vs 53.8% II). PRS class II radical hysterectomy is associated with fewer complications than PRS class III radical hysterectomy , except for the complications of lymphadenectomy . A new method that might reduce these complications is a selective lymphadenectomy represented by sentinel node biopsy . In conclusion PRS class II radical hysterectomy associated with neoadjuvant radiotherapy is a therapeutic option for the incipient stages of cervical cancer.

Tyrosinemia type I is an autosomal recessive disorder in tyrosine metabolism. In areas without expanded newborn screening, patients present with acute hepatorenal failure in early infancy. Diagnosis can be elusive when clinical presentation is non-specific and biochemical abnormalities are masked by secondary changes. This is the first Hong Kong Chinese report. A two-month-old Chinese male infant with unremarkable antenatal and postnatal history presented with progressive abdominal distension for three days. He suffered from end-stage liver failure, hypoglycemia and hepatic encephalopathy. Diagnostic work-up was complicated starting from rule-out sepsis, intestinal obstruction, volvulus, peritonitis, septic ileus, poisoning to metabolic diseases. Clinical, biochemical and genetic data was described. The patient showed increases in multiple plasma amino acids including tyrosine, phenylalanine and methionine, and hyper-excretions of 4-hydroxyphenyl-acetate, -pyruvate, and -lactate, as well as N-acetyltyrosine which could be seen in liver failure due to both tyrosinemia type I and non-metabolic conditions. Because of the volatile nature, succinylacetone was almost undetectable. The diagnosis was confirmed by genetic analysis of FAH with two novel mutations, viz. NM_000137.2:c.1063-1G>A and NM_000137.2:c.1035_1037del. Living-related liver transplantation was done. However, the patient still suffered many complications after the severe metabolic insult with hypoxic ischemic encephalopathy, cerebral atrophy, global developmental delay and cortical visual impairment. Because of the lack of expanded newborn screening in Hong Kong, this child unfortunately presented in the most severe form of tyrosinemia type I. Expanded newborn screening can save life and reduce the burden of diagnostic complexity. This illustrates the need for expanded newborn screening in Hong Kong.

Since last two decades minimally invasive techniques have revolutionized surgical field. In 2003 Pomel first described laparoscopic pelvic exenteration, since then very few reports have described minimally invasive approaches for total pelvic exenteration. We report the 10 cases of locally advanced rectal adenocarcinoma which were operated between the periods from March 1, 2017 to November 11, 2017 at the Tata Memorial Hospital, Mumbai. All male patients had lower rectal cancer with prostate involvement on magnetic resonance imaging (MRI). One female patient had uterine and fornix involvement. All perioperative and intraoperative parameters were collected retrospectively from prospectively maintained electronic data. Nine male patients with diagnosis of nonmetastatic locally advanced lower rectal adenocarcinoma were selected. All patients were operated with minimally invasive approach. All patients underwent abdominoperineal resection with permanent sigmoid stoma. Ileal conduit was constructed with Bricker's procedure through small infraumbilical incision (4-5 cm). Lateral pelvic lymph node dissection was done only when postchemoradiotherapy MRI showed enlarged pelvic nodes. All 10 patients received neoadjuvant chemo radiotherapy, whereas 8 patients received additional neoadjuvant chemotherapy. Mean body mass index was 21.73 (range 19.5-26.3). Mean blood loss was 1000 mL (range 300-2000 mL). Mean duration of surgery was 9.13 hours (range 7-13 hours). One patient developed paralytic ileus, which was managed conservatively. One patient developed intestinal obstruction due to herniation of small intestine behind the left ureter and ileal conduit. The same patient developed acute pylonephritis, which was managed with antibiotics. Mean postoperative stay was 14.6 days (range 9-25 days). On postoperative histopathology, all margins were free of tumor in all cases. Minimally invasive approaches can be used safely for total pelvic exenteration in locally advanced lower rectal adenocarcinoma. All patients had fast recovery with less blood loss. In all patients R0 resection was achieved with adequate margins. Long-term oncological outcomes are still uncertain and will require further follow-up.

Mucus pathology in cystic fibrosis (CF) has been known for as long as the disease has been recognized and is sometimes called mucoviscidosis. The disease is marked by mucus hyperproduction and plugging in many organs, which are usually most fatal in the airways of CF patients, once the problem of meconium ileus at birth is resolved. After the CF gene, CFTR, was cloned and its protein product identified as a cAMP-regulated Cl− channel, causal mechanisms underlying the strong mucus phenotype of the disease became obscure. Here we focus on mucin genes and polymeric mucin glycoproteins, examining their regulation and potential relationships to a dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR). Detailed examination of CFTR expression in organs and different cell types indicates that changes in CFTR expression do not always correlate with the severity of CF disease or mucus accumulation. Thus, the mucus hyperproduction that typifies CF does not appear to be a direct cause of a defective CFTR but, rather, to be a downstream consequence. In organs like the lung, up-regulation of mucin gene expression by inflammation results from chronic infection; however, in other instances and organs, the inflammation may have a non-infectious origin. The mucus plugging phenotype of the β-subunit of the epithelial Na+ channel (βENaC)-overexpressing mouse is proving to be an archetypal example of this kind of inflammation, with a dehydrated airway surface/concentrated mucus gel apparently providing the inflammatory stimulus. Data indicate that the luminal HCO3 − deficiency recently described for CF epithelia may also provide such a stimulus, perhaps by causing a mal-maturation of mucins as they are released onto luminal surfaces. In any event, the path between CFTR dysfunction and mucus hyperproduction has proven tortuous, and its unraveling continues to offer its own twists and turns, along with fascinating glimpses into biology.

Backgrounds/Aims Major hepato-pancreato-biliary (HPB) surgery is usually performed via an open method rather than a laparoscopic method. Postoperative ileus (POI) is a classic complication after open surgery. The purpose of this study was to determine whether polylactic film is useful in the prevention of POI. Methods A total of 179 patients who underwent major HPB surgery between 2005 and 2014, were retrospectively reviewed. A diagnosis of POI was made by a physical examination, laboratory, and radiological findings. Surgi-Wrap® polylactic film was preferentially used intraperitoneally by surgeons, just before wound closure. Results Major HPB surgery included pancreatoduodenectomy (n=48), distal or subtotal pancreatectomy (n=24), hepatectomy (n=67), other bile duct or gallbladder operations (n=35), and others (n=5). Although patients with polylactic film showed a significantly lower incidence of POI (n=3, 4.1% vs. n=14, 13.3%, p=0.041), they showed a significantly higher complication rate (n=20, 27.0% vs. n=19, 18.1%, p=0.004), particularly intra-abdominal fluid collection (n=7, 9.4% vs. n=2, 1.9%), and wound infections (n=6, 8.1% vs. n=3, 2.9%), than those who did not receive the film, respectively. Conclusions Although the polylactic film prevented POI, more complications other than POI were observed. Well-designed randomized controlled trials, using this anti-adhesive product, are needed to evaluate its effect on POI after major HPB surgery. PMID:28261699

Postoperative ileus (POI) is characterized by impaired propulsive function of the gastrointestinal tract after surgery. Although inflammation is considered to be an important pathogenesis of POI, significant data are lacking. We aim to correlate the recovery time of postoperative dysmotility with that of inflammation and mucosal permeability. An experimental POI model of guinea pig was used. Contractile activity of the circular muscle of the stomach, jejunum, ileum, and proximal colon was measured through a tissue bath study. Inflammatory cells were counted, and the expression of calprotectin and tryptase were analyzed. The expression of protease-activated receptor 2 (PAR-2), claudin-1, and claudin-2 were analyzed with immunofluorescence. The small bowel and colon showed decreased contractile amplitude in the POI groups compared to control. In contrast to the colon, the contractile amplitude of the small bowel significantly recovered in the POI group at 6 hours after the operation compared to the control group. Inflammation was highly significant in the POI groups compared to the control and sham groups, especially in the colon. Immunofluorescence showed increased PAR-2 expression in the POI groups compared to sham. The decreased claudin-1 expression and increased claudin-2 expression may suggest increased mucosal permeability of the small bowel and colon in the POI groups. Increased inflammation and mucosal permeability may play an important role in the differential recovery stages in POI. These data may provide further insights into the pathophysiology and potential new therapeutic prospects of POI.

Postoperative ileus (POI) is a transient bowel dysmotility that occurs following many types of operations and is one of the most common complications of gastrointestinal surgery. We hypothesized that enteral supplementation of glutamine after abdominal surgery would restore fuel to the small intestine, suppress oxidative stress, and lead to improvement in POI. Twelve dogs underwent distal gastrectomy and were each randomly assigned to one of two groups based on postoperative treatment: the water injection (control) group and the glutamine injection group. Water (40 ml) or L(+)-glutamine (1 g/40 ml water) was injected into the residual stomach through the gastric tube every 12 h after surgery for 7 days. Changes in the plasma and intestinal intracellular concentration of glutamine and in gastrointestinal motility were measured. The plasma and intracellular glutamine levels decreased after the operation in both groups, although the decreased intracellular glutamine levels were not significantly different than preoperative levels. The glutamine group showed a significantly smaller decrease of the plasma glutamine level compared with the control group (P < 0.05). All the dogs showed gastrointestinal dysmotility after the operation. The mean length of time between the operation and the appearance of interdigestive migrating contractions in the glutamine group was significantly shorter than in the control group (22.4 +/- 3.1 h versus 37.8 +/- 4.0 h, respectively; P < 0.05). In conclusion, glutamine could act as a motility-recovery agent after abdominal surgery and thereby decrease the duration of POI.

Postoperative ileus (POI) is a common complication after major abdominal surgery. Gum chewing has been shown to stimulate bowel motility and decrease duration of POI after abdominal surgery. We evaluated the effect of gum chewing in reducing the time to first flatus and on oral calorie intake in patients undergoing living or deceased donor liver transplantation. Patients were randomized into the sham feeding group or the control group. The sham feeding group chewed two pieces of xylitol flavored gum for 15 minutes, three times a day after extubation until oral nutrition was tolerated. The control group received the same routine care except for the gum chewing. Fifty-nine patients were randomized into the sham feeding group (n=30) or the control group (n=29). There was no difference in the time to first flatus (72 [66.1-82.9] hours vs 69.0 [57.6-77.2] hours, P=.422). Cumulative energy intake (2.8 [5.8-23.2] % vs 10.0 [8.5-15.9] %, P=.695) and length of intensive care unit stay (4.2 [3.9-5.3] days vs 4.0 [6.7-4.5] days, P=.077) were also similar. In conclusion, sham feeding with gum chewing did not shorten the duration of POI nor facilitate oral intake after liver transplantation.

Meconium ileus (MI) is a perinatal complication in cystic fibrosis (CF), which is only minimally influenced by environmental factors. We derived and examined MI prevalence (MIP) scores to assess CFTR phenotype-phenotype correlation for severe mutations. MIP scores were established using a Canadian CF population (n = 2,492) as estimates of the proportion of patients with MI among all patients carrying the same CFTR mutation, focusing on patients with p.F508del as the second allele. Comparisons were made to the registries from the US CF Foundation (n = 43,432), Italy (Veneto/Trentino/Alto Adige regions) (n = 1,788), and Germany (n = 3,596). The prevalence of MI varied among the different registries (13-21%). MI was predominantly prevalent in patients with pancreatic insufficiency carrying "severe" CFTR mutations. In this severe spectrum MIP scores further distinguished between mutation types, for example, G542X (0.31) with a high, F508del (0.22) with a moderate, and G551D (0.08) with a low MIP score. Higher MIP scores were associated with more severe clinical phenotypes, such as a lower forced expiratory volume in 1 second (P = 0.01) and body mass index z score (P = 0.04). MIP scores can be used to rank CFTR mutations according to their clinical severity and provide a means to expand delineation of CF phenotypes.Genet Med 18 4, 333-340.

It gives important information in selecting the appropriate treatment for urolithiasis to confirm the component of urinary calculus. Presently component analysis of the urinary calculus is generally performed by infrared spectroscopy which is employed by companies providing laboratory testing services in Japan. The infrared spectroscopy determines the molecular components from the absorption spectra in consequence of atomic vibrations. It has the drawback that an accurate crystal structure cannot be analyzed compared with the X-ray diffraction method which analyzes the crystal constituent based on the diffraction of X-rays on crystal lattice. The components of the urinary calculus including carbonate are carbonate apatite and calcium carbonate such as calcite. Although the latter is reported to be very rare component in human urinary calculus, the results by infrared spectroscopy often show that calcium carbonate is included in calculus. The infrared spectroscopy can confirm the existence of carbonate but cannot determine whether carbonate is originated from carbonate apatite or calcium carbonate. Thus, it is not clear whether calcium carbonate is included in human urinary calculus component in Japan. In this study, we examined human urinary calculus including carbonate by use of X-ray structural analysis in order to elucidate the origin of carbonate in human urinary calculus. We examined 17 human calculi which were reported to contain calcium carbonate by infrared spectroscopy performed in the clinical laboratory. Fifteen calculi were obtained from urinary tract, and two were from gall bladder. The stones were analyzed by X-ray powder method after crushed finely. The reports from the clinical laboratory showed that all urinary culculi consisted of calcium carbonate and calcium phosphate, while the gallstones consisted of calcium carbonate. But the components of all urinary calculi were revealed to be carbonate apatite by X-ray diffraction. The components of gallstones were shown to be calcium carbonate (one calcite and the other aragonite) not only by infrared spectroscopy but by X-ray diffraction. It was shown that component analysis of the calculus could be more accurately performed by adding X-ray diffraction method to infrared spectroscopy. It was shown that calcium carbonate existed in a gallstone. As for the carbonate in human urinary calculi, present study showed that it was not calcium carbonate origin but carbonate apatite origin.

Background: This experimental study was designed to determine if Helicobacter spp. contribute to benign gallbladder disease using polymerase chain reaction (PCR) methods. Methods: Patients with benign gallbladder disease scheduled for elective cholecystectomy at New York University Langone Medical Center were recruited from February to May 2008. Bile, gallbladder tissue and gallstones were collected. DNA was isolated from these specimens and amplified via PCR using C97F and C98R primers specific for Helicobacter spp. Appropriate positive and negative controls were used. Products were analysed with agarose gel electrophoresis, sequenced and results aligned using sequencher. Plasma was collected for detection of anti-Helicobacter pylori antibodies via enzyme-linked immunosorbent assay. Results: Of 36 patients, 12 patients' bile and/or tissue were positive for Helicobacter spp. by PCR. Species were most homologous with H. pylori, although other Helicobacter spp. were suggested. Six of 12 patients demonstrated anti-Helicobacter antibodies in plasma, suggesting that the remaining six might have demonstrated other species besides H. pylori. Four of six plasma samples with anti-Helicobacter antibodies were anti-CagA (cytotoxin associated gene) negative. Discussion: Helicobacter spp. can be detected in bile and gallbladder tissue of patients with benign gallbladder disease. The contribution of these bacteria to the pathophysiology of gallbladder disease and gallstone formation requires further study. PMID:20495657

Little information is available on a long-term follow-up in Bartter syndrome type I and II. Clinical presentation, treatment and long-term follow-up (5.0-21, median 11 years) were evaluated in 15 Italian patients with homozygous (n = 7) or compound heterozygous (n = 8) mutations in the SLC12A1 (n = 10) or KCNJ1 (n = 5) genes. Thirteen new mutations were identified. The 15 children were born pre-term with a normal for gestational age body weight. Medical treatment at the last follow-up control included supplementation with potassium in 13, non-steroidal anti-inflammatory agents in 12 and gastroprotective drugs in five patients. At last follow-up, body weight and height were within normal ranges in the patients. Glomerular filtration rate was <90 mL/min/1.73 m(2) in four patients (one of them with a pathologically increased urinary protein excretion). In three patients, abdominal ultrasound detected gallstones. The group of patients with antenatal Bartter syndrome had a lower renin ratio (P < 0.05) and a higher standard deviation score (SDS) for height (P < 0.05) than a previously studied group of patients with classical Bartter syndrome. Patients with Bartter syndrome type I and II tend to present a satisfactory prognosis after a median follow-up of more than 10 years. Gallstones might represent a new complication of antenatal Bartter syndrome.

So far, the components responsible for the neuroprotective effects of Calculus bovis are unclear. Cholesterol, one of the major components in Calculus bovis, is easily oxidized into oxysterols, which possess direct or indirect neuroprotective effects proved by our and others' previous studies. Therefore, a liquid chromatography with mass spectrometry method coupled with ultrasonic extraction and solid-phase extraction was developed for the determination of neuroprotective oxysterols in Calculus bovis, human gallstones, and traditional Chinese medicine preparations. Chromatographic separation was achieved on a C18 column with isocratic elution at a flow rate of 1 mL/min. The established method showed good linearity (R(2) > 0.998), sensitivity with low limits of detection (0.06-0.39 μg/g), acceptable precisions (relative standard deviations ≤ 7.4%), stability (relative standard deviations ≤ 5.9%), and satisfactory accuracy (92.4-102.9%) for all analytes identified by different retention times, which could be applied for the determination of oxysterols. Five kinds of oxysterols proved to function as neuroprotectants were detected at different concentrations. Among them, 7β-hydroxycholesterol and cholestane-3β,5α,6β-triol were rather abundant in the samples. It could be concluded that the potential neuroprotective components in Calculus bovis may be these oxysterols. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Born in secret in 1987 and developed in an atmosphere of scepticism throughout 1988, laparoscopic cholecystectomy triumphed in 1989 and 1990, causing a veritable revolution in the world of general surgery. The 777 consecutive cases that are reported in this chapter reflect the spirit of these various periods. From conservatively restrictive, our indications widened to include 90% of gallstone cases. For us the sclero-atrophic gallbladder still constitutes the greatest endoscopic challenge and should be reserved for the most experienced operators. The rates for mortality (0.1%) and complications (3.3%), which include three common bile duct injuries (0.4%), are comparable to, if not better than, those for traditional cholecystectomy. The quality of recovery is markedly better: near absence of pain, short hospitalization, return to normal physical activity within 10 days, rapid return to work and preservation of the abdominal musculature in sportspeople. These advantages are unavailable to the 5.5% of patients for whom an intraoperative conversion to an open procedure is necessary. Their recovery is that of traditional cholecystectomy, which itself is far from being poor. The large multicentre studies, such as those carried out in France and Belgium recently, reporting 3708 cases, have reached identical conclusions. Laparoscopic cholecystectomy is set to become the gold standard for treatment of gallstones and is the first step towards surgical techniques of the 21st century which will be performed within the musculocutaneous envelope of the intact human body.

In the present study, we investigated expression pattern of Cholecystokinin type A receptor (CCKAR) in relation to its commonly studied polymorphism (rs1800857, T/C) in gallstone disease (GSD) patients and controls. A total of 502 subjects (272 GSD and 230 controls) were enrolled, and genotyping was performed by evaluating restriction fragments of PstI digested DNA. For analyzing expression pattern of CCKAR in relation to polymorphism, gallbladder tissue samples from 80 subjects (GSD-55; control-25) were studied. Expression of CCKAR mRNA was evaluated by reverse transcriptase-PCR and confirmed using real-time PCR. Protein expression was evaluated by enzyme-linked immunosorbent assay. We observed significantly (p < 0.0001) lower expression of CCKAR mRNA and protein in GSD tissues as compared with control. Significantly higher frequency of A1/A1 genotype (C/T transition) (p = 0.0005) was observed for GSD as compared with control. Expression of CCKAR protein was found to be significantly lower (p < 0.0001) in A1/A1 genotype as compared with other genotypes for GSD patients. Perhaps, this is the first report providing evidence of alteration in CCKAR expression in relation to its polymorphism elucidating the molecular pathway of the disease. Additional investigations with lager sample size are needed to confirm these findings.

INTRODUCTION Magnetic resonance cholangiopancreatography (MRCP) is commonly used to evaluate the biliary tree, although indications for patients who require inpatient imaging are not fully defined. The aim of this study was to evaluate inpatient MRCP performed on surgical patients and to devise a treatment pathway for these patients. MATERIAL AND METHODS All adult inpatient MRCP examinations between January 2012 and December 2013 were reviewed. Demographic, clinical and radiological data were collated. RESULTS During the study period, 271 inpatient MRCP were requested, of which 234 examinations were included. The majority of patients were female (n=140) and the median age was 63 years (range 16-93 years). Surgical admissions accounted for 171 (73%) of cases. Indications for inpatient MRCP include gallstone-related complications (n=173; 74%), malignant process (n=17; 7%) and other indications (n=44; 19%). Overall, inpatient MRCP led to further inpatient interventions in 22% (gallstone group, n=32, 18%; patients with malignancy, n=8, 47%; other indications, n=12, 27%). The median duration of inpatient MRCP from request to examination was 2 days (range 0-15 days) and median reporting after examination was 1 day (range 0-14 days). DISCUSSION AND CONCLUSION Improved access and timely reporting of iMRCP may reduce length of hospital stay. Inpatient MRCP also led to further inpatient interventions, in particular, in patients with malignancy.

Sickle cell disease is a public health problem in Africa. The aim of this prospective study was to evaluate per and post-operative complications of laparoscopic cholecystectomy in sickle cell children in Senegal. from January 1999 to December 2006, an anesthetic protocol was applied to 39 sickle cell children undergoing a cholecystectomy. Among them, 20 experienced laparoscopic cholecystectomy. All these 20 patients had previously suffered from sickle cell visceral complications and were classified as ASA II (11 cases) and as ASA III (9 cases). Blood transfusion program aimed at sustaining haemoglobin level between 10 and 12 g/dl was implemented. The preoperative monitoring and anesthesia management were the same for these patients. During perioperative period, the prevention of pain, hypovolemia, hypothermia and acidosis was achieved. The mean insufflation duration of laparoscopy was 23 min (17-60 min), the mean surgery duration was 55 min (40-110 min), and the mean anesthesia duration was 78 min (88-135 min). Postoperative complications occurred in 9 patients: acute chest syndrome (n=2), postoperative hemolysis (n=5), vaso-occlusive crisis (n=2). Laparoscopic cholecystectomy can be carried out in sickle cell children affected with gallstones, provided that general anaesthetic rules were respected. An appropriate pre-, per- and postoperative anaesthesia is mandatory to reduce postoperative complications in children with sickle cell disease. Searching for early diagnosis of gallstones before occurrence of visceral complications should allow further optimal laparoscopic surgery.

OBJECTIVE: To test the hypothesis that progesterone alters sphincter of Oddi and gallbladder function and, therefore, bile flow dynamics. SUMMARY BACKGROUND DATA: Although the effects of progesterone on the biliary tract have been implicated in the increased incidence of gallstones among women, the specific effects of prolonged elevation of progesterone levels, such as occurs with contraceptive progesterone implants and during pregnancy, on the sphincter of Oddi and biliary flow dynamics are still incompletely understood. METHODS: Adult female prairie dogs were randomly assigned to receive subcutaneous implants containing either progesterone or inactive pellet matrix only. Hepatic bile partitioning and gallbladder emptying were determined 14 days later using 99mTc-Mebrofenin cholescintigraphy. RESULTS: Significantly less hepatic bile partitioned into the gallbladder in progesterone-treated than in control animals. The gallbladder ejection fraction was significantly reduced from 73+/-6% in controls to 59+/-3% in the progesterone-treated animals. The rate of gallbladder emptying was significantly reduced from 3.6+/-0.3%/minute to 2.9+/-0.1%/minute. CONCLUSIONS: Progesterone administered as subcutaneous implants alters partitioning of hepatic bile between gallbladder and small intestine and, therefore, gallbladder filling. Progesterone also significantly impairs gallbladder emptying in response to cholecystokinin. The effects of progesterone on the sphincter of Oddi and the gallbladder may contribute to the greater prevalence of gallstones and biliary motility disorders among women. Images Figure 1. Figure 2.

To investigate the long-term follow-up of distal intestinal obstruction syndrome (DIOS) in Israeli cystic fibrosis (CF) patients. This is a multi-center, comparative, retrospective study in which we reviewed the medical records of all CF patients from three major CF centers in Israel who were treated in the period from 1980 to 2012. Patients diagnosed with DIOS were defined as the study group. The patients were diagnosed with DIOS based on their clinical presentation and typical findings on either abdominal X-ray or computerized tomography scan. For the control group, CF patients with no DIOS were matched to the patients in the study group for age, sex, and cystic fibrosis transmembrane conductance regulator (CFTR) mutations. For both groups, the collected data included age, sex, CFTR genotype, weight, height, and body mass index. Clinical data included respiratory function tests in the last five years prior to the study, respiratory function test immediately before and after the DIOS event, number of hospitalizations, sputum culture results, and CF-related conditions diagnosed according to the CF clinical practice guidelines. In the study group, data on the DIOS treatment and tendency for DIOS recurrence were also analyzed. The medical charts for a total of 350 CF patients were reviewed. Of the 350 CF patients, 26 (7.4%) were diagnosed with DIOS. The control group included 31 CF patients with no DIOS diagnosis. The mean follow-up period was 21.6 ± 8.2 years. The total of DIOS episodes in the follow-up period was 60. The distribution of DIOS episodes was as follows: 6/26 (23.1%) study patients had one episode of DIOS in their lifetime, 7/26 (26.9%) had two episodes, 7/26 (26.9%) had three episodes, and 6/26 (23.1%) had four or more episodes. Compared to the control group, DIOS patients had a significantly higher incidence of meconium ileus in the past (65.4% vs 0%, respectively, P < 0.02), more Aspergillus spp. colonization (34.6% vs 3.2%, respectively, P < 0.02), and a higher number of hospitalizations due to respiratory exacerbations (8.6 vs 6.2 mean total hospitalizations per follow-up period, respectively, P < 0.02). No other significant differences were found between the control and study groups. The conservative treatment of DIOS, which mainly includes hydration and stool softeners, was successful in 82% of the episodes. The survival rate was similar for both groups. CF patients with DIOS suffer from recurrent hospitalizations and airway pathogen acquisition. Although recurrence of DIOS is common, conservative treatment is successful in most patients.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

Our experience with 17 patients with spinal cord injuries (SCI) acquired in the Lebanon War, 1982, is described. The SCI were due to gunshot wounds in 12 patients and to other causes in 5. Two laparotomies and one thoracotomy were performed. Corticosteroids were not seen to influence recovery, nor was laminectomy, which was performed in three cases. Complications such as pressure sores, hydronephrosis, ileus and deep vein thrombosis were rare or did not occur. Three high quadriplegics died. Based on our experience, we recommend conservative treatment and rehabilitation in acute SCI.

Background/study aim: During the last several years, endoscopic ultrasound (EUS)-guided pancreatic fluid collections' (PFC) drainage has evolved into the preferred drainage technique. Recently, self-expanding metallic stents (SEMS) have been used as an alternative to double pigtail stents, with the advantage of providing a larger diameter fistula, thereby decreasing the risk of early obstruction and also allowing for direct endoscopic exploration of the cavity. The aim of this study was to evaluate the technical and clinical success, safety, and outcome of patients undergoing EUS-guided drainage of complex PFC using SEMS. The study was conducted at two tertiary hospitals from January 2010 to January 2013. All patients with PFC referred for endoscopic drainage were enrolled in a prospective database. The inclusion criteria were: (1) patients with pseudocysts or walled-off necrosis based on the revised Atlanta classification; (2) symptomatic patients with thick PFC; (3) PFC that persisted more than 6 weeks; and (4) large PFC diameter (≥ 9 cm). The exclusion criteria consisted of coagulation disorders, PFC bleeding or infection, and failure-to-inform written consent. A total of 16 patients (9 females, 7 males; mean age 52.6, range 20 - 82) underwent EUS drainage with SEMS. There were 14 cases of pseudocysts and 2 cases of walled-off necrosis. The etiologies of the PFC were mainly gallstones (8 of 16 patients, 50 %) and alcohol (5 of 16 patients, 31 %). Technical success was achieved in 100 % of the cases. All patients had a complete resolution of the PFC. Transmural EUS-guided drainage of complex PFC using SEMS is feasible, appears safe, and is efficacious. However, the exchange of the UC (uncovered)-SEMS for plastic stents is mandatory within 1 week. Future prospective studies, preferably multicenter studies, comparing SEMS versus traditional plastic stents for the drainage of PFC are warranted.

To characterise multi-level obstruction in terms of prevalence, obstructive sleep apnoea severity and predictive factors, and to collect epidemiological data on upper airway morphology in obstructive sleep apnoea patients. Retrospective review of 250 obstructive sleep apnoea patients. On clinical examination, 171 patients (68.4 per cent) had multi-level obstruction, 49 (19.6 per cent) had single-level obstruction and 30 (12 per cent) showed no obstruction. Within each category of obstructive sleep apnoea severity, multi-level obstruction was more prevalent. Multi-level obstruction was associated with severe obstructive sleep apnoea (more than 30 events per hour) (p = 0.001). Obstructive sleep apnoea severity increased with the number of obstruction sites (correlation coefficient = 0.303, p < 0.001). Multi-level obstruction was more likely in younger (p = 0.042), male (p = 0.045) patients, with high body mass index (more than 30 kg/m2) (p < 0.001). Palatal (p = 0.004), tongue (p = 0.026) and lateral pharyngeal wall obstructions (p = 0.006) were associated with severe obstructive sleep apnoea. Multi-level obstruction is more prevalent in obstructive sleep apnoea and is associated with increased severity. Obstruction at certain anatomical levels contributes more towards obstructive sleep apnoea severity.

Previous incomplete studies investigating the potential of chewing gum (CG) in patients undergoing colorectal resection did not obtain definitive conclusions. This updated meta-analysis was therefore conducted to evaluate the effect and safety of CG versus standard postoperative care protocols (SPCPs) after colorectal surgery. Total 26 RCTs enrolling 2214 patients were included in this study. The CG can be well-tolerated by all patients. Compared with SPCPs, CG was associated with shorter time to first flatus (weighted mean difference (WMD) -12.14 (95 per cent c.i. -15.71 to -8.56) hours; P < 0.001), bowl movement (WMD -17.32 (-23.41 to -11.22) hours; P < 0.001), bowel sounds (WMD -6.02 (-7.42 to -4.63) hours; P < 0.001), and length of hospital stay (WMD -0.95 (-1.55 to -0.35) days; P < 0.001), a lower risk of postoperative ileus (risk ratio (RR) 0.61 (0.44 to 0.83); P = 0.002), net beneficial and quality of life. There were no significant differences between the two groups in overall complications, nausea, vomiting, bloating, wound infection, bleeding, dehiscence, readmission, reoperation, mortality. The potentially eligible randomized controlled trials (RCTs) that compared CG with SPCPs for colorectal resection were searched in PubMed, Embase, Cochrane library, China National Knowledge Infrastructure (CNKI), and Chinese Wanfang databases through May 2016. The trial sequential analysis was adopted to examine whether a firm conclusion for specific outcome can be drawn. CG is benefit for enhancing return of gastrointestinal function after colorectal resection, and may be associated with lower risk of postoperative ileus.

To investigate the therapeutic value of Gastrografin in shortening duration of prolonged postoperative ileus (PPOI) after elective colorectal surgery. Gut wall edema is central to the pathogenesis of PPOI. Hyperosmotic, orally administered, water-soluble contrast media such as Gastrografin are theoretically capable of mitigating this edema. A double-blinded, placebo-controlled, randomized trial was conducted. Participants were allocated to receive 100 mL of Gastrografin (Exposure Group) or flavored distilled water (Control Group) administered enterally. Other aspects of management were standardized. Resolution of PPOI was assessed 12-hourly. Eighty patients were randomized equally, with 5 in the Exposure Group and 4 in the Control Group excluded from analysis. Participants were evenly matched at baseline. Mean duration of PPOI did not differ between Exposure and Control Groups (83.7 vs 101.3 hours; P = 0.191). When considering individual markers of PPOI resolution, Gastrografin did not affect time to resolution of nausea and vomiting (64.5 vs 74.3 hours; P = 0.404) or consumption of oral diet (75.8 vs 90.0 hours; P = 0.297). However, it accelerated time to flatus or stool (18.9 vs 32.7 hours; P = 0.047) and time to resolution of abdominal distension (52.8 vs 77.7 hours; P = 0.013). There were no significant differences between groups in nasogastric output; analgesia, antiemetic, or fluid requirement; complications; or length of stay. Gastrografin is not clinically useful in shortening an episode of PPOI characterized by upper and lower gastrointestinal symptoms. It may however be of therapeutic benefit in the subset of PPOI patients who display lower gastrointestinal symptoms exclusively after surgery.

Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit.

Perspectives on the importance of postoperative ileus.

Post-operative ileus (POI) is a common condition after surgery. Failure to restore adequate bowel function after surgery generates a series of complications and it is associated to patients frustration and discomfort, worsening their perioperative experience. Even mild POI can be source of anxiety and could be perceived as a drop out from the "straight-forward" pathway. Enhanced recovery programmes have emphasized the importance of early commencement of oral diet, avoiding the ancient dogmata of prolonged gastric decompression and fasting. These protocols with early oral feeding and mobilization have led to improved perioperative management and have decreased hospital length of stay, ameliorating patient's postoperative experience as well. Nonetheless, the incidence of POI is still high especially after major open abdominal surgery. In order to decrease the incidence of POI, minimally-invasive surgical approaches and minimization of surgical manipulation have been suggested. From a pharmacological perspective, a meta-analysis of pro-kinetics showed beneficial results with alvimopan, although its use has been limited by the augmented risk of myocardial infarction and the high costs. A more simple approach based on the postoperative use of chewing-gum has provided some benefits in restoring bowel function. From an anaesthesiological perspective, epidural anaesthesia/analgesia does not only reduce the postoperative consumption of systemic opioids but directly improve gastrointestinal function and should be considered where possible, at least for open surgical procedures. POI represents a common and debilitating complication that should be challenged with multi-disciplinary approach. Prospective research is warranted on this field and should focus also on patient s reported outcomes.

Although postoperative ileus (POI) is considered multifactorial, intestinal inflammation resulting from manipulation-induced mast cell activation is recognized as an important pathophysiological mechanism. Therefore, mast cell stabilization may represent a new therapeutic approach to shortening POI. The aim of this paper was to study the effect of ketotifen, a mast cell stabilizer, on postoperative gastrointestinal transit in patients who underwent abdominal surgery. In this pilot study, 60 patients undergoing major abdominal surgery for gynecological malignancy with standardized anesthesia were randomized to treatment with ketotifen (4 or 12 mg) or placebo. Patients were treated for 6 days, starting 3 days before surgery. Gastric emptying of liquids, selected as a primary outcome parameter, was measured 24 h after surgery using scintigraphy. Secondary end points were (scintigraphically assessed) colonic transit, represented as geometrical center of activity (segment 1(cecum) to 7(stool)) and clinical parameters. Gastric retention 1 h after liquid intake was significantly reduced by 12 mg (median 3% (1-7), P=0.01), but not by 4 mg ketotifen (18% (3-45), P=0.6) compared with placebo (16% (5-75)). Twenty-four hour colonic transit in placebo was 0.8 (0.0-1.1) vs. 1.2 (0.2-1.4) colon segments in the 12 mg ketotifen group (P=0.07). Abdominal cramps were significantly relieved in patients treated with 12 mg ketotifen, whereas other clinical parameters were not affected. Ketotifen significantly improves gastric emptying after abdominal surgery and warrants further exploration of mast cell stabilizers as putative therapy for POI.

Postoperative ileus (POI) is an iatrogenic complication of abdominal surgery, mediated by a severe inflammation of the muscularis externa (ME). Previously, we demonstrated that intravenous application of the tetravalent guanylhydrazone semapimod (CNI-1493) prevents POI, but the underlying mode of action could not definitively be confirmed. Herein, we investigated the effect of a novel orally active salt of semapimod (CPSI-2364) on POI in rodents and distinguished between its inhibitory peripheral and stimulatory central nervous effects on anti-inflammatory vagus nerve signaling. Distribution of radiolabeled orally administered CPSI-2364 was analyzed by whole body autoradiography and liquid scintillation counting. POI was induced by intestinal manipulation with or without preoperative vagotomy. CPSI-2364 was administered preoperatively via gavage in a dose- and time-dependent manner. ME specimens were assessed for p38-MAP kinase activity by immunoblotting, neutrophil extravasation, and nitric oxide production. Furthermore, in vivo gastrointestinal (GIT) and colonic transit were measured. Autoradiography demonstrated a near-exclusive detection of CPSI-2364 within the gastrointestinal wall and contents. Preoperative CPSI-2364 application significantly reduced postoperative neutrophil counts, nitric oxide release, GIT deceleration, and delay of colonic transit time, while intraoperatively administered CPSI-2364 failed to improve POI. CPSI-2364 also prevents postoperative neutrophil increase and GIT deceleration in vagotomized mice. Orally administered CPSI-2364 shows a near-exclusive dispersal in the gastrointestinal tract and effectively reduces POI independently of central vagus nerve stimulation. Its efficacy after single oral dosage affirms CPSI-2364 treatment as a promising strategy for prophylaxis of POI.

Although the role of cholesterol absorption by the gallbladder epithelium in gallstone formation is well established, the exact process is poorly understood. Potential candidates for regulation of transepithelial cholesterol transport are suggested to be two large membrane multiple ligand receptors, megalin and cubilin. We studied the expression of these two proteins in both acalculous and calculous human gallbladder epithelia. Adult human gallbladder tissues were received from 21 patients (9 men, 12 women) who had undergone cholecystectomy. The patients were divided into two groups: group A (calculous gallbladder group; 5 men, 6 women; mean age 64.4 +/- 11.1 years) with cholelithiasis, and group B (acalculous gallbladder group; 4 men, 6 women; mean age 55.3 +/- 16.1 years). In the gallbladder tissues megalin and cubilin expression was studied by immunohistochemistry and conventional RT-PCR, and gene expression levels were estimated by real-time RT-PCR. Both megalin and cubilin gene transcripts were found in total RNA preparations from acalculous gallbladder. In contrast, in preparations from calculous gallbladder, none or only one of the proteins was detected. Immunoreactive proteins were detected in the simple columnar acalculous gallbladder epithelium but not in the calculous gallbladder epithelium. Our results show different expression patterns of the two proteins in calculous gallbladders and acalculous gallbladders. In the latter both proteins are expressed, suggesting an association with gallstone formation and implying a putative role of the two proteins in cholesterol endocytosis. In other words, the presence of both proteins may be essential for the prevention of stone formation.

Gallbladder cancer (GBC) is a rare malignancy characterized by high invasiveness and poor survival. In a nation-wide cancer survey, the age-standardized incidence rate of GBC was the highest in Jeju Island compared to 15 other provinces in Korea. The purpose of this study was to compare the clinical outcomes of GBC according to the nature of diagnosis, that is, incidental versus non-incidental. Consecutive patients who were newly diagnosed with GBC at the Digestive Disease Center and Department of Internal Medicine, Cheju Halla General Hospital, between November 2008 and November 2011, were enrolled and divided into 2 groups: incidental gallbladder cancer (IGBC) and non-incidental gallbladder cancer (NIGBC). Clinical outcomes were retrospectively compared between the two groups. Seventy-nine patients were enrolled and analyzed in our study. Thirty-three (41.8%) and 46 (58.2%) were identified as IGBC and NIGBC, respectively. The proportions of patients with gallstone disease, gallbladder polyp, and cholecystectomy were significantly different between the two groups. Additionally, the median survival rate was significantly higher for patients with IGBC than for those with NIGBC (11.4, 95% confidence interval, 5.6-13.7 vs 4.0, 95% confidence interval 3.03-5.96 months; p=0.01) during a median follow-up period of 5.7 months. Patients with IGBC showed better clinical prognosis than those with NIGBC. Therefore, patients with gallstone disease or gallbladder polyps, major predictive risk factors for IGBC, should undergo advanced work-up for chelecystectomy.

To study the bacteriological profile, and to determine predictors of bile infection and septic complications following laparoscopic cholecystectomy. This cross-sectional study reviewed 1248 laparoscopic cholecystectomy cases performed between January 1994 and December 2007 by one surgical team at the Jordan University Hospital, Amman, Jordan. Bile cultures were performed for all patients and statistical analysis was performed on culture results and postoperative complications as well as, on the possible predictors of bile infection including age, gender, associated diseases, preoperative retrograde cholangiopancreatography (ERCP), and indications for surgery. Uncomplicated gallstone disease was diagnosed in 993 patients (79.6%), 221 patients (17.7%) had acute cholecystitis, and 34 patients (2.7%) had jaundice. Associated morbidities were present in 513 patients (41.1%), preoperative ERCP was performed for 132 patients (10.6%), and postoperative septic complications developed in 25 patients (2%). Bile culture was positive in 250 patients (20%), 134 (53.6%) of whom had gram negative bacteria, 73 (29.2%) had gram positive bacteria, and 43 (17.2%) had mixed cultures. The chi-square test has shown that positive bile culture is significantly associated with age, gender, preoperative ERCP, associated morbidities, and complicated gallbladder disease, whereas multinomial regression analysis has shown that age and preoperative ERCP were the only significant predictors of bile infection. Bile infection commonly complicates gallstone disease, and it can be influenced by age and preoperative endoscopic interventions, but it does not influence the occurrence of postoperative septic complications.

Acute pancreatitis is increasingly one of the most important acute gastrointestinal conditions throughout much of the world, although incidence and aetiology varies across countries and regions. This study investigated regional and national patterns in the incidence and aetiology of acute pancreatitis, demographic patterns in incidence and trends over time in incidence across Europe. A structured review of acute pancreatitis incidence and aetiology from studies of hospitalised patient case series, cohort studies or other population based studies from 1989 to 2015 and a review of trends in incidence from 1970 to 2015 across all 51 European states. The incidence of acute pancreatitis was reported from 17 countries across Europe and ranged from 4.6 to 100 per 100 000 population. Incidence was usually highest in eastern or northern Europe, although reported rates often varied according to case ascertainment criteria. Of 20 studies that reported on trends in incidence, all but three show percentage increases over time (overall median increase = 3.4% per annum; range = -0.4%-73%). The highest ratios of gallstone to alcohol aetiologies were identified in southern Europe (Greece, Turkey, Italy and Croatia) with lowest ratios mainly in eastern Europe (Latvia, Finland, Romania, Hungary, Russia and Lithuania). The incidence of acute pancreatitis varies across Europe. Gallstone is the dominant aetiology in southern Europe and alcohol in eastern Europe with intermediate ratios in northern and western Europe. Acute pancreatitis continues to increase throughout most of Europe. Copyright © 2017. Published by Elsevier B.V.

The aim of this study was to determine the cost-effectiveness of a new strategy for the preoperative detection of patients that will likely benefit from a cholecystectomy, using simple criteria that can be applied by surgeons. Criteria for a cholecystectomy indication are: (1) having episodic pain; (2) onset of pain 1 year or less before the outpatient clinic visit. The cost-effectiveness of the new strategy was evaluated against current practice using a decision analytic model. The incremental cost-effectiveness of applying criteria for a cholecystectomy for a patient with abdominal pain and gallstones was compared to applying no criteria. The incremental cost-effectiveness ratio (ICER) was expressed as extra costs to be invested to gain one more patient with absence of pain. Scenarios were analyzed to assess the influence of applying different criteria. The new strategy of applying one out of two criteria resulted in a 4 % higher mean proportion of patients with absence of pain compared to current practice with similar costs. The 95 % upper limit of the ICER was €4114 ($4633) per extra patient with relief of upper abdominal pain. Application of two out of two criteria resulted in a 3 % lower mean proportion of patients with absence of pain with lower costs. The new strategy of using one out of two strict selection criteria may be an effective but also a cost-effective method to reduce the proportion of patients with pain after cholecystectomy.

Fascioliasis is an often-neglected zoonotic disease and currently is an emerging infection in Iraq. Fascioliasis has two distinct phases, an acute phase, exhibiting the hepatic migratory stage of the fluke's life cycle, and a chronic biliary phase manifested with the presence of the parasite in the bile ducts through hepatic tissue. The incidence of Fascioliasis in Sulaimaniyah governorate was unexpected observation. We believe that shedding light on this disease in our locality will increase our physician awareness and experience in early detection, treatment in order to avoid unnecessary surgeries. We retrospectively evaluated this disease in terms of the demographic features, clinical presentations, and managements by reviewing the medical records of 18 patients, who were admitted to the Sulaimani Teaching Hospital and Kurdistan Centre for Gastroenterology and Hepatology. Patients were complained from hepatobiliary and/or upper gastrointestinal symptoms and diagnosed accidentally with Fascioliasis during hepatobiliary surgeries and ERCP by direct visualization of the flukes and stone analysis. Elevated liver enzymes, white blood cells count and eosinophilia were notable laboratory indices. The dilated CBD, gallstones, liver cysts and abscess were found common in radiological images. Fascioliasis diagnosed during conventional surgical CBD exploration and choledochodoudenostomy, open cholecystectomy, surgical drainage of liver abscess, ERCP and during gallstone analysis. Fascioliasis is indeed an emerging disease in our locality, but it is often underestimated and ignored. We recommend the differential diagnosis of patients suffering from Rt. Hypochondrial pain, fever and eosinophilia. The watercress ingestion was a common factor in patient's history.

The purpose was 1) to prospectively determine the prevalence of adverse events necessitating intensive care unit (ICU) monitoring in gallstone pancreatitis (GP) and 2) To identify admission prognostic indicators that predict the need for ICU unit monitoring. Prospective laboratory data, physiologic parameters, and APACHE II scores were gathered on 102 patients with GP over 14 months. Adverse events were defined as cardiac, respiratory, or renal failure, gastrointestinal bleeding, stroke, sepsis, and necrotizing pancreatitis. Patients were divided into Group 1 (no adverse events, n=95) and Group 2 (adverse events, n=7). There were no deaths and 7 (7%) adverse events, including necrotizing pancreatitis (3), cholangitis (2), and cardiac (2). APACHE 11 > or = 5 (P < 0.005), blood urea nitrogen (BUN) > or = 12 mmol/L (P < 0.005), white blood cell count (WBC) > or = 14.5 x 10(9)/L, (P < 0.001), heart rate > or = 100 bpm (P < 0.001), and glucose > or = 150 mg/dL (P < 0.005) were each independent predictors of adverse events. The sensitivity and specificity of these criteria for predicting severe complications requiring ICU care varied from 71 to 86 per cent and 78 to 87 per cent, respectively. The prevalence of adverse events necessitating ICU care in GP patients is low. Glucose, BUN, WBC, heart rate, and APACHE II scores are independent predictors of adverse events necessitating ICU care. Single criteria predicting the need for ICU care on admission are readily available on admission.

Gastrointestinal motility in space motion sickness

Gastrointestinal symptoms in space motion sickness (SMS) are significantly different from those in ordinary motion sickness (MS). Recording and tabulation of sounds was the only technique that could be used as a measure of motility during spaceflight operations. There were 17 subjects, six unaffected by SMS, who made ambulatory recordings preflight and inflight. With one exception, all those affected had sharply reduced sounds, while those unaffected had increases or moderate reductions. The mechanism of vomiting in SMS appears to be secondary to this ileus, in contrast to vomiting in ordinary MS, where the emesis center is thought to be directly triggered by the vestibular system.

Pathologic aerophagia is sometimes seen in patients with neurologic disorders. It rarely causes massive bowel distention, ileus, and volvulus. Here, we report the use of esophagogastric separation and abdominal esophagostomy via jejunal interposition to prevent bowel distention caused by severe aerophagia in 2 patients with neurologic disorders in whom the usual nonoperative methods of management failed. In both cases, swallowed air was evacuated via the jejunostomy, eliminating bowel distention. This operation may be useful in patients with neurologic disorders associated with severe aerophagia.

We report the case of a 39-year-old woman with ileus resulting from a small bowel incarceration underneath the right common iliac artery. The patient had a history of a radical trachelectomy with laparoscopic pelvic lymphadenectomy ("Dargent's operation") for cervical carcinoma. After dissection of the iliac vessels, a small bowel loop could slide underneath the common iliac artery. The hernia was closed by gluing a collagen patch over the right common iliac artery onto the retroperitoneal cavity. To our knowledge, such a case has not previously been reported in the medical literature.

[Post-operative course in tetraplegics after urological surgers (author's transl)].

The authors report their experience with 33 tetraplegics undergoing surgery. The operations were varied, endoscopic (resection of the bladder neck, of the prostate or striate sphincter, lithot-itiasis) or surgical (lombotomies, transintentinal cutaneous ureterostomies). The post-operative course may be dramatic or even fatal (acute hypertension with cerebral haemorrhage). Respiratory insufficiency poses no particular problem and can be controlled. Epidural anaesthesia maintained for several days makes it possible to avoid the more serious problems: -- autonomic hyperreflectivity, -- delayed resolution of ileus and digestive complication. The authors hence use epidural anaesthesia routinely and are satisfied with the technique.

A 45-year-old male, body packer, who confessed to have swallowed 44 packages of cocaine in a total dose of approx. 360 g, was admitted to hospital because of clinical signs of acute intoxication with cocaine followed by ileus. The emergency surgical gastrotomy was initiated, and the conglomerate of Scotch tape and packages with cocaine were removed. Small rupture of one package of cocaine in a body packer stomach caused acute poisoning with cocaine, confirmed additionally by the presence of its metabolites in the urine. Mechanical pylorostenosis provoked by cocaine packages required emergency surgical operation.
