    An 82-year-old woman without any previous medical history arrived in the emergency department with severe pain in the entire abdomen since 5 h. Blood tests showed, apart from a CRP of 28 mg/l, no abnormalities. We decided to perform an abdominal ultrasound, which showed an easily compressible gallbladder, containing a small, mobile gallstone and free fluid in the abdomen. During ultrasound-guided punction of this fluid, bile is aspirated. We performed laparoscopy and confirmed a large amount of intraperitoneal bile. Upon inspecting the gallbladder a perforation is seen in the anti-hepatic side of the gallbladder. After performing a cholecystectomy, we opened the gallbladder and detected a dissection-like lesion, which provided access to the peritoneal cavity. The confirmed diagnosis was acute onset free perforation of the gallbladder. The perforation was probably caused by the small obstructing gallstone seen on ultrasound or by another small stone, which could not be visualized.

    Introduction Gall bladder perforation is associated with high mortality rates and therefore must be recognised and managed promptly. We present an unusual presentation of spontaneous gall bladder perforation. Case presentation An elderly lady with multiple medical co-morbidities was admitted with sepsis following a fall. Initial assessment lead to a diagnosis of pneumonia, however a rapidly expanding right flank mass was incidentally noted during routine nursing care. Imaging studies were inconclusive, however incision and drainage of the mass revealed bile stained pus draining cutaneously from an acutely inflamed gallbladder. The patient made a good recovery following surgery, and was discharged with outpatient follow-up. Discussion Despite focussed post-hoc history taking she denied any prodromal symptoms of cholecystitis. In addition to reporting an unusual cause for a common presentation, we highlight the importance of a full body examination in the context of sepsis, regardless of whether the source has been identified. In addition, we advocate that surgical intervention in sepsis should not be delayed by imaging in cases where an abscess is suspected. Conclusions Percutaneous abscesses arising from the gallbladder are a rare but potentially serious consequence of acute cholecystitis, and may present in a wide variety of locations. Therefore it is imperative to conduct a full body inspection in the septic patient, even when a source has been identified. PMID:26686488

    Gallbladder perforation is a serious clinical condition. A definitive diagnosis is contentious before surgery. We discuss a case where a young patient with Crohn's disease taking oral steroids presented with an acute abdomen. CT scan demonstrated a perforated gallbladder without evidence of gallstones. The patient underwent an emergency cholecystectomy and peritoneal lavage. The history and clinical findings of this patient are reviewed to highlight perforation of the gallbladder in relation to steroid therapy.

    The main cause of perforation of the gallbladder is cholecystitis with or without cholelithiasis. In old age, spontaneous perforation of gallbladder can be due to decrease in its blood supply, which can be due to atherosclerosis, focal vasospasm or localized vasculitis. Perforation of gallbladder is associated with high morbidity and mortality, if left untreated. Here we report a case of a 60-year-old male with perforation of gallbladder. PMID:27785327

    An older lady presented 1 week after being discharged from hospital with acute cholecystitis. She suffered a sudden onset lower abdominal pain and was in hypovolaemic shock upon arrival. It was noted that she had been on antiplatelet therapy after suffering a recent myocardial infarction, an immunosuppressor and steroids for rheumatoid arthritis. Her admission bloods revealed a platelet count of 83 with normal clotting factors. After resuscitation, a CT scan confirmed fluid in the abdomen possibly arising from the right subhepatic space. During laparotomy, bleeding was noted from a perforated and ischaemic-looking gallbladder, with an intact cystic artery and duct and no biliary calculi evident. The gallbladder was removed and the patient was transferred to intensive therapy unit. She recovered well within the subsequent 8 days and was discharged. Her histology described ‘haemorrhage within the gallbladder wall along with oedema, fibrosis and patchy inflammation and no signs of malignancy or gangrene’. PMID:22778467

    An 86 year-old woman with a past medical history significant for abdominal hernia and Alzheimer dementia presented to the Emergency Department with a 24 hour history of acute right upper quadrant pain associated with nausea and non-bilious emesis. Physical exam revealed right sided abdominal tenderness with associated mass. All laboratory values were within normal ranges. Both abdominal ultrasound and computed tomography of the abdomen/pelvis revealed a large distended gallbladder with wall thickening and gallstones. Based on presentation and radiologic findings, the emergency general surgery service was consulted for suspected acute cholecystitis. The patient was then admitted for intravenous antibiotics and scheduled for laparoscopic cholecystectomy the following day. Intra-operative findings revealed volvulus with acute necrosis of the entire gallbladder. The gallbladder had a long pedunculated cystic duct and artery that was detorsed before proceeding with resection. Postoperatively, the patient did well and was discharged a few days later tolerating a regular diet.

    Gallbladder perforation is a potentially life-threatening condition commonly seen as a complication of acute cholecystitis. Urgent surgical intervention is often needed to reduce serious morbidity and mortality. It presents a diagnostic challenge due to nonspecific symptoms, leading to a delay in diagnosis. Imaging plays a vital role in early identification of this potentially fatal condition and evaluation by more than one imaging modality may be required to make the diagnosis. Knowledge of specific and ancillary imaging findings is crucial to avoid misdiagnosis. In this article, we will review the risk factors, pathophysiology, and surgical classification of gallbladder perforation and discuss the role of multimodality imaging in its diagnosis. Differential diagnoses on imaging will also be discussed.

    Primary gallbladder lymphoma is rare. Perforated cholecystitis due to primary gallbladder lymphoma and not related to chemotherapy has been unreported. We report the case of an 80-year-old woman presenting with an acute abdomen and clinical peritonitis. Her serum amylase was raised to 878 iu/l. Urgent computed tomography revealed generalised free fluid with a normal pancreas and was non-diagnostic as to the underlying pathology. An emergency laparotomy revealed bilious peritonitis with a necrotic patch on a distended gallbladder. A cholecystectomy was carried out and histology of the gallbladder revealed a marginal zone lymphoma.

    Necrotizing fasciitis continues to carry a very high mortality and prolonged morbidity. Gallstones have previously not been reported as a cause of this condition. We report a patient who presented with gallbladder perforation leading to necrotizing fasciitis of the anterior abdominal wall. The only organism isolated was Escherichia Coli, cultured from necrotic issue.

    We present an unusual case of necrotizing fasciitis in the upper abdominal wall caused by penetrating perforation of the gallbladder. It was manifested as an elastic and reddish abdominal swelling with severe tenderness, but no peritoneal irritation. Computed tomography (CT) demonstrated water density with a slightly elevated CT value and air bubbles in the subcutaneous space. The preoperative diagnosis was subcutaneous abscess with fasciitis. At surgery, necrotizing fasciitis and subcutaneous abscess secondary to penetrating perforation of the gallbladder were revealed. Cholecystectomy and peritoneal irrigation were performed. Although no tumor was evident during surgery, a tumor located close to the perforation site was found just after the operation. Pathological examination revealed gallbladder carcinoma without stones. There have been very few previous reports of necrotizing fasciitis following gallbladder perforation. The presentation, diagnosis, and management of fasciitis, as well as carcinoma of the gallbladder with perforation, are discussed.

    Gallbladder perforation (GBP) is rare and as a complication of typhoid fever is extremely rare. We present two consecutive patients with GBP diagnosed incidentally at laparotomy. Information on the management of two patients with gallbladder perforation seen at Federal Medical Centre Azare in June and October 2008 was extracted from their case records. The two patients were both males aged 13 years and 16 years. They both presented with high fever of more than 2 weeks duration; and abdominal pain and distension. Both patients had features of generalised peritonitis. Pre-operative diagnoses of typhoid enteric perforation were made based on a positive Widal test. Intra-operative findings however, were that of bile peritonitis and gallbladder perforation. Both had cholecystectomy. Culture of the bile aspirate yielded Salmonella typhi. Gallbladder perforation secondary to typhoid fever should be considered as a differential diagnosis in patients with suspected typhoid enteric perforation in typhoid fever endemic region.

    2014-01-01

    Introduction Mesh fixation with tacker systems is common in laparoscopic and open hernia repair. Complications due to absorbable tackers are rare and have not been described in the literature. However, we report a case of gallbladder erosion due to tacker dislocation. Methods An open hernia repair was performed using an intraperitoneal onlay mesh for a recurrent parastomal hernia after two previous mesh repairs in a 67-year-old patient. Results On postoperative day 2, the patient was reoperated because of a dislocated tacker that eroded and perforated the fundus region of the gallbladder. Putatively, tacker dislocation occurred owing to imbalanced traction forces. Initially, the mesh was fixed with absorbable tackers around the stoma on the right and transmuscular suture fixation was carried out on the left abdominal side. On revision surgery, tension forces to the right were therefore neutralised by additional transmuscular sutures on the right side. Conclusions Absorbable tackers in open hernia repair provide a safe and effective mesh fixation if tension forces are carefully avoided. PMID:25245719

    Background and study aims: Endoscopic retrograde pancreatocholangiography (ERCP) is associated with many types of adverse events (AEs) but idiopathic perforation of the gallbladder (IPGB) is very rare. Pancreatobiliary reflux is one of the factors involved with occurrence of IPGB 1. Here we present a case of acalculous gallbladder perforation as an AE following the insertion of an indwelling endoscopic nasal pancreatic drainage (ENPD) tube (a pancreatic stent) to obtain pancreatic fluid. In this case, acute pancreatobiliary reflux might have been caused by the insertion of the ENPD-tube. PMID:27540570

    A case of gallbladder perforation is presented in which a small bile leak was demonstrated by cholescintigraphy while the patient was receiving meperidine, but not after meperidine was discontinued. The scintigrams obtained during meperidine therapy also showed a pattern of bile-duct obstruction. It is suggested that increased biliary pressure secondary to meperidine admininstration permitted visualization of the leak. Use of narcotic drugs may be a useful pharmocologic intervention in cases of peritonitis due to small obscure bile leaks.

    An 82-year-old man presented with signs and symptoms that were suggestive of acute cholecystitis. He underwent a laparoscopic cholecystectomy. During the intervention, a wooden foreign body was removed from the infiltrated omentum, probably after it had perforated the gastric antrum. The gastric perforation had led to a secondary infection of the gallbladder. The presumed gastric perforation was treated conservatively, and the patient recovered well and was discharged after 7 days. Secondary inflamed gallbladders are rare; the current case is, to the best of our knowledge, the first case reporting a secondary infection of the gallbladder due to a gastric perforation. Clinicians should be aware of possible ingestion of foreign bodies in elderly patients wearing dental prosthetic devices.

    We present a rare case of type II Niemeier gallbladder perforation(GBP) developed as a complication of acute calculous cholecystitis. A 76-year-old man was admitted to our surgical unit with the presumptive diagnosis of acute cholecystitis. CT scan revealed a subcapsular collection developed on the visceral surface of the right hepatic lobe. It was communicating through a thin hypodense band with the cystic duct, distal to an impacted stone. Through laparoscopy the collection was confirmed to be a subcapsular liver abscess secondary to GBP.The cholecystectomy and the abscess cavity treatment were completely handled via laparoscopic approach. The paper demonstrates that laparoscopic approach can be a safe and feasible method in order to treat both the cause and the complication in this situation. Early diagnosis and appropriate minimally invasive approach are the key to manage this rarity. Celsius.

    Spontaneous perforation of the uterus is rare, its incidence being about 0.01% − 0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of pus was found in the peritoneal cavity. There were no abnormal findings in the alimentary tract, liver, or gallbladder. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological investigation of the surgical specimen revealed endometritis and myometritis of the uterus; but there was no evidence of malignancy, and the cervical canal was patent. Although spontaneously perforated pyometra is rare, a perforated pyometra should therefore also be considered when elderly women present with acute abdominal pain. PMID:17485806

    Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form. A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement. In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity. The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    2017-01-01

    Gallbladder perforation (GBP) represents a rare, but potentially life-threatening, complication of acute cholecystitis. GBP is subdivided into three categories whereas the development of biloma is extremely rare. The present case study reports on a 40-year-old man with a 10-year history of calculus cholecystitis, who was referred to The First Affiliated Hospital of Nanjing Medical University (Nanjing, China) for the surgical treatment of an emerging massive hepatic entity with insidious symptoms and normal laboratory tests. A preoperative imaging study demonstrated the collection with internal septations and mural nodules, but no visible communication with the biliary system. Given the suspected biliary cystic tumor, a laparotomy was performed and the lumen was scattered with papillae. An intraoperative frozen section examination illustrated a simple hepatic cyst. Biochemical analysis of the collection and histopathology of the gallbladder and capsule substantiated the diagnosis of biloma formation due to GBP. The purpose of the present case report was to demonstrate how a pinhole-sized perforation with extravasation of unconcentrated bile from the gallbladder may result in insidious clinical presentation and an undetected leak site. According to the clinicopathological characteristics and composition, formation of biloma should be classified as type IV GBP. To differentiate bilomas with intracystic septations and mural nodules from BCTs is difficult via a preoperative examination, and the definitive diagnosis should be based on a histological examination. Laparotomy with frozen section examination may be the optimal approach in such a case. PMID:28123732

    A spontaneous (non-traumatic) gallbladder perforation with gallstone disease is not common. Concomitant development of a liver abscess is a very rare complication observed in such cases. A few cases of intrahepatic gallbladder perforations with chronic liver abscesses have been described. However, a patient series summarising classical and atypical presentations, relevant imaging studies, and the role of surgical and non-surgical options are lacking. We report a short case series on this rare complication of intrahepatic gallbladder perforations and share our experience of management of this condition. PMID:27055407

    Nonoperative gallbladder drainage methods for acute cholecystitis include percutaneous transhepatic gallbladder drainage and percutaneous transhepatic gallbladder aspiration, endoscopic nasogallbladder drainage and gallbladder stenting via a transpapillary endoscopic approach, and EUS-guided nasogallbladder drainage and gallbladder stenting via a transmural endoscopic approach. A systematic review was performed to evaluate the current potential role of each gallbladder drainage technique for acute cholecystitis. MEDLINE, EMBASE, and manual searches were performed to identify pertinent English-language articles. The technical success rate, clinical success rate, and the frequency of adverse events in percutaneous transhepatic gallbladder aspiration (n = 122) and percutaneous transhepatic gallbladder drainage (n = 246) were 93% and 98%, 83% and 90%, and 0.8% and 3.7%, respectively. In contrast, the technical success rate, clinical success rate, and the frequency of adverse events in endoscopic nasogallbladder drainage (n = 194) and endoscopic gallbladder stenting (n = 127) were 81% and 96%, 75% and 88%, and 3.6% (n = 7) and 6.3% (n = 8), respectively. Although there have been 2 small case series of successful EUS-guided transmural nasogallbladder drainage (total n = 12), the procedure was technically and clinically successful in all of the patients with 2 adverse events. Only 1 case of successful EUS-guided gallbladder stent placement without any procedure-related adverse events has been reported. Retrospective studies, small number of patients, and lack of randomized, controlled trials. Although prospective evaluation of the feasibility, safety, and efficacy of these various approaches will help identify the most suitable therapeutic modality for patients with acute cholecystitis, endoscopic gallbladder drainage may have a high potential as an alternative drainage method in acute cholecystitis. 2010 American Society for Gastrointestinal Endoscopy.

    2007-10-01

    Gallbladder stasis is associated to experimental acute cholecystitis. Impaired contractility could be, at least in part, the result of inflammation-induced alterations in the neuromuscular function. This study was designed to determine the changes in gallbladder neurotransmission evoked by acute inflammation and to evaluate the protective and therapeutic effects of melatonin. Experimental acute cholecystitis was induced in guinea pigs by common bile duct ligation for 2 days, and then the neuromuscular function was evaluated using electrical field stimulation (EFS; 5-40 Hz). In a group of animals with the bile duct ligated for 2 days, a deligation of the duct was performed, and after 2 days, the neuromuscular function was studied. The EFS-evoked isometric gallbladder contraction was significantly lower in cholecystitic tissue. In addition, inflammation changed the pharmacological profile of these contractions that were insensitive to tetrodotoxin but sensitive to atropine and omega-conotoxin, indicating that acute cholecystitis affects action potential propagation in the intrinsic nerves. Nitric oxide (NO)-mediated neurotransmission was reduced by inflammation, which also increased the reactivity of sensitive fibers. Melatonin treatment prevented qualitative changes in gallbladder neurotransmission, but it did not improve EFS-induced contractility. The hormone recovered gallbladder neuromuscular function once the biliary obstruction was resolved, even when the treatment was started after the onset of gallbladder inflammation. These findings show for the first time the therapeutic potential of melatonin in the recovery of gallbladder neuromuscular function during acute cholecystitis.

    Early cholecystectomy for patients with acute cholecystitis may not be possible in some clinical settings. Percutaneous gallbladder aspiration (PGBA) offers an alternative approach, but the benefits and risks of this procedure are unclear. We synthesized data on the outcomes of PGBA in acute cholecystitis patients using data sources from online databases, including MEDLINE and EMBASE, and bibliographies of included studies from January 2000 through December 2015. Two reviewers independently reviewed and critiqued the quality of each study. Seven eligible studies met our criteria. The success rates in single PGBA and repetitive PGBA (2–4 times) were 50% to 93% and 76% to 96%, respectively. Complication rates were 0% to 8% and were unrelated to the size of needle gauge used for aspiration and the number of aspirations. Salvage percutaneous cholecystostomy (PC) and urgent surgery were required in 0% to 43% of patients and 0% to 4% of patients, respectively. Two studies with antibiotic instillation had clinical success rates of 95% and 96%. In conclusion, repetitive PGBA combined with antibiotic instillation and salvage PC are useful alternatives to early cholecystectomy in patients with acute cholecystitis. PMID:27695167

    Background/Aims Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided GBS (EUS-GBS) have been proposed as safe and effective modalities for gallbladder drainage. Methods Data from patients with cholecystitis were prospectively collected from August 2004 to May 2013 from two United States academic university hospitals and analyzed retrospectively. The following treatment algorithm was adopted. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and cystic duct stenting was initially attempted. If deemed feasible by the endoscopist, EUS-GBS was then pursued. Results During the study period, 139 patients underwent endoscopic gallbladder drainage. Among these, drainage was performed in 94 and 45 cases for benign and malignant indications, respectively. Successful endoscopic gallbladder drainage was defined as decompression of the gallbladder without incidence of cholecystitis, and was achieved with ERCP and cystic duct stenting in 117 of 128 cases (91%). Successful endoscopic gallbladder drainage was also achieved with EUS-guided gallbladder drainage using transmural stent placement in 11 of 11 cases (100%). Complications occurred in 11 cases (8%). Conclusions Endoscopic gallbladder drainage techniques are safe and efficacious methods for gallbladder decompression in non-surgical patients with comorbidities. PMID:26473125

It was noted that he had a history of a total gastrectomy (with D2 lymphadenectomy) 1 month ago. His admission bloods revealed total bilirubin was 142.2 umol/L, indirect bilirubin of 107.6 umol/L and white cell count of 20.05×10(9)/L. A color doppler ultrasound scan confirmed fluid and gas around liver and hilus lienis while the gallbladder cannot be detected. During Computed Tomography (CT) guided puncture positioning technology and setting a three-channel tube, about 400 ml of foul smell hazel turbid liquid was drained out. He was diagnosed as gallbladder perforation and he was underwent conservative treatment consist of drainage, banning diet, total parenteral nutrition and intravenous antibiotics. Then he recovered well within the subsequent 10 days and was discharged.

    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

    A 40-year-old woman presented with acute epigastric pain with vomiting. Within 24 hours, the pain spread to the right periumbilical region. /sup 99m/Tc disofenin hepatobiliary scan failed to demonstrate the gallbladder on a 60-minute view. The presumative diagnosis of acute cholecystitis was thought to be confirmed on this basis by the patient's physicians. However, a 75-minute view demonstrated filling of the gallbladder. In hepatobiliary scanning for acute abdominal pain, delayed views (2 to 24 hours) are recommended when the gallbladder is not visualized on the 60-minute view. If the gallbladder is visualized, cystic duct obstruction can be excluded and diagnoses such as pancreatitis, acalculous cholecystitis, and acute appendicitis should be investigated.

    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

    IMPORTANCE In the traditional model of acute appendicitis, time is the major driver of disease progression; luminal obstruction leads inexorably to perforation without timely intervention. This perceived association has long guided clinical behavior related to the timing of appendectomy. OBJECTIVE To evaluate whether there is an association between time and perforation after patients present to the hospital. DESIGN, SETTING, AND PARTICIPANTS Using data from the Washington State Surgical Care and Outcomes Assessment Program (SCOAP), we evaluated patterns of perforation among patients (≥18 years) who underwent appendectomy from January 1, 2010, to December 31, 2011. Patients were treated at 52 diverse hospitals including urban tertiary centers, a university hospital, small community and rural hospitals, and hospitals within multi-institutional organizations. MAIN OUTCOMES AND MEASURES The main outcome of interest was perforation as diagnosed on final pathology reports. The main predictor of interest was elapsed time as measured between presentation to the hospital and operating room (OR) start time. The relationship between in-hospital time and perforation was adjusted for potential confounding using multivariate logistic regression. Additional predictors of interest included sex, age, number of comorbid conditions, race and/or ethnicity, insurance status, and hospital characteristics such as community type and appendectomy volume. RESULTS A total of 9048 adults underwent appendectomy (15.8% perforated). Mean time from presentation to OR was the same (8.6 hours) for patients with perforated and nonperforated appendicitis. In multivariate analysis, increasing time to OR was not a predictor of perforation, either as a continuous variable (odds ratio = 1.0 [95% CI, 0.99-1.01]) or when considered as a categorical variable (patients ordered by elapsed time and divided into deciles). Factors associated with perforation were male sex, increasing age, 3 or more comorbid

    Acute cholecystitis is a common cause of emergency hospital admission. Ultrasonography (US) plays a significant role in the prompt diagnosis of this medical condition. However, it is difficult to find a radiologist in attendance for performing gallbladder US "beyond daytime and on weekends." With this standpoint, we decided to assess prospectively the accuracy of surgeon-performed gallbladder US for identifying acute cholecystitis in patients with cholelithiasis. Seventy-one consecutive patients awaiting elective or acute gallbladder surgery were included in this study. The US findings of surgeons and radiologists are compared with the histopathology reports. The sensitivity, specificity, accuracy, PPV (positive predictive value), and NPV (negative predictive value) for acute cholecystitis by both surgeon-performed ultrasound (SPUS) and radiologist-performed ultrasound (RPUS) were evaluated. Both radiologists and surgeons visualized the gallstones of each patient in all cases. The sensitivity, specificity, accuracy, and NPV for acute cholecystitis by SPUS were 84.2%, 92.1%, 90%, and 94%, respectively, whereas the sensitivity, specificity, accuracy, and NPV for acute cholecystitis by RPUS were 92.3%, 85.9%, 87.1%, and 98%, respectively. Both SPUS and RPUS had a high accuracy rate in electing the acute cholecystitis. Our data support the fact that the use of US by general surgeons is effective in the diagnosis of acute cholecystitis.

    The authors present the case of a patient with acute, right iliac fossa abdominal syndrome, simulating acute apendicitis. In the course of the intervention it was noted that the syndrome was determined by an acute Meckel diverticulitis, perforated by a foreign body (fish bone). In view of making the diagnosis of acute diverticulitis, that cannot be assessed before surgery, the importance is stressed of the correlation of the clinical aspects with the apendicular lesions found in the course of the operation, and, when there is no satisfactory concordance, careful checking of the cecum becomes necessary, as well as of the right annexe and of the ileon over at least three feet.

    Impaired smooth muscle contractility is a hallmark of acute acalculous cholecystitis. Although free cytosolic Ca2+ ([Ca2+]i) is a critical step in smooth muscle contraction, possible alterations in Ca2+ homeostasis by cholecystitis have not been elucidated. Our aim was to elucidate changes in the Ca2+ signaling pathways induced by this gallbladder dysfunction. [Ca2+]i was determined by epifluorescence microscopy in fura 2-loaded isolated gallbladder smooth muscle cells, and isometric tension was recorded from gallbladder muscle strips. F-actin content was quantified by confocal microscopy. Ca2+ responses to the inositol trisphosphate (InsP3) mobilizing agonist CCK and to caffeine, an activator of the ryanodine receptors, were impaired in cholecystitic cells. This impairment was not the result of a decrease in the size of the releasable pool. Inflammation also inhibited Ca2+ influx through L-type Ca2+ channels and capacitative Ca2+ entry induced by depletion of intracellular Ca2+ pools. In addition, the pharmacological phenotype of these channels was altered in cholecystitic cells. Inflammation impaired contractility further than Ca2+ signal attenuation, which could be related to the decrease in F-actin that was detected in cholecystitic smooth muscle cells. These findings indicate that cholecystitis decreases both Ca2+ release and Ca2+ influx in gallbladder smooth muscle, but a loss in the sensitivity of the contractile machinery to Ca2+ may also be responsible for the impairment in gallbladder contractility.

    The inflammatory disease of the pancreas can be classified like us acute or chronic pancreatitis. The pancreatitis incidence vary according to the countries and the causes which originate it; consumption of alcohol, gallotone, metabolic factors, drugs and others. The anatomopathological spectrum of the acute pancreatitis vary from pancreatitis edematosa, which usually is a light disorder with a limited evolution, to the pancreatitis necrosante, in which the grade of pancreas necrosis keeps relation with the importance of the attack and with its general declarations that in his evolution can give place to numerous complications, among which the colonic perforation is not frequent. We present a 75-year-old woman, with acute pancreatitis necrohaemorragic for colelitiasis multiple that evolves favorably at the beginning of the medical treatment, but she presented a later colonic perforation as a rare complication of the pancreatic process.

    Since the publication of the Tokyo Guidelines in 2007 and their revision in 2013, appropriate management for acute cholecystitis has been more clearly established. Since the last revision, several manuscripts, especially for alternative endoscopic techniques, have been reported; therefore, additional evaluation and refinement of the 2013 Guidelines is required. We describe a standard drainage method for surgically high-risk patients with acute cholecystitis and the latest developed endoscopic gallbladder drainage techniques described in the updated Tokyo Guidelines 2018 (TG18). Our study confirmed that percutaneous transhepatic gallbladder drainage should be considered the first alternative to surgical intervention in surgically high-risk patients with acute cholecystitis. Also, endoscopic transpapillary gallbladder drainage or endoscopic ultrasound-guided gallbladder drainage can be considered in high-volume institutes by skilled endoscopists. In the endoscopic transpapillary approach, either endoscopic naso-gallbladder drainage or gallbladder stenting can be considered for gallbladder drainage. We also introduce special techniques and the latest outcomes of endoscopic ultrasound-guided gallbladder drainage studies. This article is protected by copyright. All rights reserved.

    Causes may be found in most cases of acute pancreatitis, however no etiology is found by clinical, biological and imaging investigations in 30% of these cases. Our objective was to evaluate results from endoscopic ultrasonography (EUS) for diagnosis of gallbladder microlithiasis in patients with unexplained (idiopathic) acute pancreatitis. Thirty-six consecutive non-alcoholic patients with diagnoses of acute pancreatitis were studied over a five-year period. None of them showed signs of gallstones on transabdominal ultrasound or tomography. We performed EUS within one week of diagnosing acute pancreatitis. Diagnosis of gallbladder microlithiasis on EUS was based upon findings of hyperechoic signals of 0.5-3.0 mm, with or without acoustic shadowing. All patients (36 cases) underwent cholecystectomy, in accordance with indication from the attending physician or based upon EUS diagnosis. Twenty-seven patients (75%) had microlithiasis confirmed by histology and nine did not (25%). EUS findings were positive in twenty-five. Two patients had acute cholecystitis diagnosed at EUS that was confirmed by surgical and histological findings. In two patients, EUS showed cholesterolosis and pathological analysis disclosed stones not detected by EUS. EUS diagnosed microlithiasis in four cases not confirmed by surgical treatment. In our study, sensitivity, specificity and positive and negative predictive values to identify gallbladder microlithiasis (with 95% confidence interval) were 92.6% (74.2-98.7%), 55.6% (22.7-84.7%), 86.2% (67.4-95.5%) and 71.4% (30.3-94.9%), respectively. Overall EUS accuracy was 83.2%. EUS is a very reliable procedure to diagnose gallbladder microlithiasis and should be used for the management of patients with unexplained acute pancreatitis. This procedure should be part of advanced endoscopic evaluation.

    The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

    Acute cholecystitis is a common diagnosis and surgery is the standard of care for young and fit patients. However, due to high risk of postoperative morbidity and mortality, surgical management of critically ill patients remains a controversy. It is not clear, whether the increased risk of perioperative complications associated with the management of critically ill patients with acute cholecystitis is secondary to reduced physiologic reserve per se or to the severity of gallbladder inflammation. A retrospective analysis of prospectively collected data of patients undergoing laparoscopic cholecystectomy for acute cholecystitis in a university hospital over a three-year-period was performed. The ASA scores at the time of presentation were used to categorize patients into two groups. The study group consisted of critically ill patients with ASA 3 and 4, while the control group was made up of fit patients with ASA 1 and 2. Both groups were compared with regard to perioperative data, postoperative outcome and extent of gallbladder inflammation on histopathology. Two hundred and seventeen cases of acute cholecystitis with complete charts were available for analysis. The study group included 67 critically ill patients with ASA 3 and 4, while the control group included 150 fit patients with ASA 1 and 2. Both groups were comparable with regard to perioperative data. Histopathology confirmed severe cholecystitis in a significant number of cases in the study group compared to the control group (37 % vs. 18 %, p = 0.03). Significantly higher rates of morbidity and mortality were recorded in the study group (p < 0.05). Equally, significantly more patients from the study group were managed in the ICU (40 % vs. 8 %, p = 0.001). Critically ill patients presenting with acute cholecystitis are at increased risk for extensive gallbladder inflammation. The increased risk of morbidity and mortality seen in such patients might partly be secondary to severe acute

    Spontaneous perforation of pyometra is a rare pathologic condition that presents as diffuse peritonitis. This report describes an interesting case of spontaneous uterine perforation that mimicked gut perforation clinically and was finally diagnosed at exploratory laparotomy. Although rare, perforation of pyometra should be kept as one of the differential diagnosis in an elderly woman with an acute abdomen. A high index of suspicion is required to make a correct preoperative diagnosis, which allows early intervention, thus reducing morbidity and mortality. PMID:18324325

    The gallbladder volvulus is defined as the rotation of the gallbladder on its mesentery along the axis of the cystic duct and cystic artery. It is an extremely rare surgical disease and definitive diagnosis is usually made during surgery. A 78 year old woman presented with upper right quadrant abdominal pain, with no comorbidities and no other accompanying symptoms. Analysis revealed haemodynamic instability and leukocytosis. Computed tomography of abdomen showed an acute cholecystitis. During emergency right hypochondrium laparotomy, the gallbladder was found to be twisted counterclockwise with huge gangrenous gallbladder distal. Open cholecystectomy was performed and after the surgery, the patient was discharged in a few days. Gallbladder volvulus, or gallbladder torsion, is a rare condition and should be considered when clinical and imaging findings of complicated cholecystitis are present. The performance of urgent laparoscopic surgery would be first option to avoid perforation, peritonitis and haemodynamic instability. Copyright © 2016 Academia Mexicana de Cirugía A.C.

    Acute abdominal pain is commonly encountered in the emergency department (ED), but a diagnosis of gall bladder perforation (GBP) is rarely considered in the absence of predisposing factors. This article will highlight the risk factors, diagnosis, and management of GBP, a rare but potentially life-threatening biliary pathology. A 73-year-old diabetic man presented to the ED with a 12-h history of severe upper abdominal pain. He was hemodynamically stable, but abdominal examination showed distention, guarding, and diffuse tenderness. Abdominal X-ray study showed mildly distended small bowel loops without any air-fluid levels. Abdominal sonography revealed mild ascites and pericholecystic fluid collection but no gall bladder calculi. Laboratory reports documented a white blood cell count of 13,700/mm(3) and elevated serum amylase of 484 IU/L. A contrast-enhanced computed tomography (CT) scan of the abdomen suggested discontinuity of the gall bladder wall along with fluid accumulation in the pericholecystic, perihepatic, right subphrenic, and right paracolic spaces. In view of the possibility of spontaneous GBP developing as a complication of acute acalculous cholecystitis, laparotomy was planned. At surgery, several liters of bile-stained peritoneal fluid were aspirated and inspection of the gall bladder revealed a perforation at the fundus. After cholecystectomy, the patient had an uneventful recovery. The diagnosis of spontaneous gall bladder perforation should be considered in elderly patients presenting to the ED with symptoms and signs of peritonitis even in the absence of pre-existing gall bladder disease. Abdominal CT scan is an invaluable tool for the diagnosis, and early surgical intervention is usually life-saving. Copyright © 2012 Elsevier Inc. All rights reserved.

    2016-01-01

    We evaluated clinical factors such as age, gender, predisposing diseases and ultrasonographic findings that determine clinical outcome of acute acalculous inflammatory gallbladder diseases in children. The patients were divided into the four age groups. From March 2004 through February 2014, clinical data from 131 children diagnosed as acute acalculous inflammatory gallbladder disease by ultrasonography were retrospectively reviewed. Systemic infectious diseases were the most common etiology of acute inflammatory gallbladder disease in children and were identified in 50 patients (38.2%). Kawasaki disease was the most common predisposing disease (28 patients, 21.4%). The incidence was highest in infancy and lowest in adolescence. The age groups were associated with different predisposing diseases; noninfectious systemic disease was the most common etiology in infancy and early childhood, whereas systemic infectious disease was the most common in middle childhood and adolescence (P = 0.001). Gallbladder wall thickening was more commonly found in malignancy (100%) and systemic infection (94.0%) (P = 0.002), whereas gallbladder distension was more frequent in noninfectious systemic diseases (60%) (P = 0.000). Ascites seen on ultrasonography was associated with a worse clinical course compared with no ascites (77.9% vs. 37.7%, P = 0.030), and the duration of hospitalization was longer in patients with ascites (11.6 ± 10.7 vs. 8.0 ± 6.6 days, P = 0.020). In conclusion, consideration of age and predisposing disease in addition to ultrasonographic gallbladder findings in children suspected of acute acalculous inflammatory gallbladder disease might result in better outcomes.

    Acute perforated cholecystitis (APC) is probably the most severe complication of acute cholecystitis. However, data on the outcome of cholecystectomy for APC are limited to small series. This study investigated the outcomes of cholecystectomy for APC. Data from a prospectively maintained quality control database in Germany were analyzed. Cases with APC were compared to cases without gallbladder perforation with regard to demographic characteristics, clinical findings and surgical outcomes. A total of 5704 patients with APC were compared to 39,661 patients without perforation. Risk factors for APC included: the male gender, advanced age (>65 years), ASA score >2, elevated white blood count (WBC), positive findings on abdominal ultrasound sonography and fever. The APC group differed significantly from the control group with regard to fever (29.8 vs. 12.2 %), elevated WBC (83.8 vs. 65.4 %) and positive findings from ultrasound sonography (84.9 vs. 78.9 %), p < 0001. Preoperative computed tomography (CT) was ordered significantly more often in the APC group compared to the control group (2.3 vs. 1.0 %, p = 0.001). Surgery lasted significantly longer in the APC group (92.3 ± 40.8 vs. 73.7 ± 34.1, p < 0.001). The rates of conversion (18.9 vs. 6.8 %), bile duct injury (1.4 vs. 0.5 %), re-intervention (6.9 vs. 2.9 %) and mortality (4.3 vs. 1.3 %) were significantly higher in the APC group (p < 0.001). Similarly, the length of stay (13.4 ± 11.4 vs. 9.0 ± 8.3, p < 0.001) was significantly longer in the APC group. Acute perforated cholecystitis is a severe complication of acute cholecystitis. Surgical dissection could be challenging with high risks of bile duct injury and conversion. The rates of morbidity and mortality are higher compared to those of patients without perforation.

    Delay in presentation is associated with increased perforation rates in acute appendicitis. Perforation is linked to greater morbidity, and greater risk of complications. The purpose of this study is to evaluate whether ethnicity or insurance status is associated with differences in presentation and outcomes in adult patients with acute appendicitis. A retrospective analysis was performed for all patients 18 y of age and over with acute appendicitis between July 1, 2005 and December 31, 2008 at the only teaching hospital in the region. χ(2) and regression analyses were used to evaluate the impact of ethnicity and insurance status on perforation rates. A total of 1003 patients with acute appendicitis were identified, of which 239 (23.8%) were perforated. Those patients with public insurance were significantly more likely to have perforated disease (P < 0.001). Additionally, those patients in the older age groups (41-64 and ≥65) were also significantly more likely (P < 0.001) to have perforated appendicitis (35.8% and 38.24%, respectively, versus 19.2% for those 18-40). The patients who presented with perforation had a greater length of stay (2.71 ± 2.14 versus 6.04 ± 3.91 d, P < 0.001). In our population sample, ethnicity does not predict perforation rates in adult patients with acute appendicitis. Significant risks of perforation appear related to insurance status and age.

    Background Hydrogen sulfide (H2S) has recently been shown to play an important role in the digestive system, but the role of endogenous H2S produced locally in the gallbladder is unknown. The aim of this study was to investigate whether gallbladder possesses the enzymatic machinery to synthesize H2S, and whether H2S synthesis is changed in gallbladder inflammation during acute acalculous cholecystitis (AC). Methods Adult male guinea pigs underwent either a sham operation or common bile duct ligation (CBDL). One, two, or three days after CBDL, the animals were sacrificed separately. Hematoxylin and eosin-stained slides of gallbladder samples were scored for inflammation. H2S production rate in gallbladder tissue from each group was determined; immunohistochemistry and western blotting were used to determine expression levels of the H2S-producing enzymes cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) in gallbladder. Results There was a progressive inflammatory response after CBDL. Immunohistochemistry analysis showed that CBS and CSE were expressed in the gallbladder epithelium, muscular layer, and blood vessels and that the expression increased progressively with increasing inflammation following CBDL. The expression of CBS protein as well as the H2S-production rate was significantly increased in the animals that underwent CBDL, compared to those that underwent the sham operation. Conclusions Both CBS and CSE are expressed in gallbladder tissues. The expression of these enzymes, as well as H2S synthesis, was up-regulated in the context of inflammation during AC. PMID:24349344

    Early cholecystectomy is currently the gold standard treatment for acute cholecystitis (AC). However, the acceptability and safety of this strategy remain in dispute. The aim of this study was to clarify the role of percutaneous transhepatic gallbladder aspiration (PTGBA) in the early management of AC in a single center. A total of 147 consecutive patients who were treated with PTGBA for AC from 2008 to 2012 were included in the study. The therapeutic outcomes and adverse events were evaluated. A single PTGBA was adequate for 96 (65.3%) patients with AC. Of the remaining 51 patients, 43 (29.3%) showed an improvement after repeated PTGBA and/or percutaneous transhepatic gallbladder drainage (PTGBD), while semi-emergency cholecystectomy was needed in eight patients. Although five patients experienced adverse events (intra-abdominal hemorrhage in two, bile leakage in two and gallbladder hemorrhage in one), no patient died of treatment-related complications. Subsequently, 87 (59.2%) patients underwent cholecystectomy after PTGBA (a single PTGBA in 48 and repeated PTGBA and/or PTGBD in 39 patients). No significant differences were observed in the conversion rate from laparoscopic surgery to open cholecystectomy, operative time or intraoperative hemorrhage volume between the two groups.

    Palatal perforation is an uncommon complication seen in children with acute lymphoblastic leukemia undergoing chemotherapy. This may impact basic functions, such as speech, swallowing, chewing, affecting the quality of life (QOL). Prosthetic rehabilitation of the palatal perforation with obturator can optimally restore function, thereby improving and enhancing the QOL of these patients. PMID:28900336

    The present study assessed conservative management of acute cholecystitis (AC) with a focus on percutaneous transhepatic gallbladder aspiration (PTGBA). Consecutive 275 patients with AC who underwent PTGBA were reviewed. Patients aged ≥80 years and/or with American Society of Anesthesiologists score III to IV and/or performance status 3 to 4 were defined as high risk. Patients were classified according to duration from symptom onset to first PTGBA: within 3 days (early PTGBA) or over 3 days (late PTGBA). They were also classified according to duration from first PTGBA to surgery: within 30 days (early surgery) or over 30 days (late surgery). A total of 263 patients (95.6%) showed recovery after PTGBA. There were no significant differences in operating time, blood loss, operating procedure, conversion rate to open surgery, postoperative complications, or postoperative hospital stay between the early and late PTGBA groups or between the early and late surgery groups. No significant complications associated with PTGBA or surgery were observed, including in those at high risk. Percutaneous transhepatic gallbladder aspiration can be a useful alternative for most patients with AC, including those at high risk. Elective cholecystectomy can be performed safely regardless of the timing of PTGBA or surgery. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    The optimal timing of cholecystectomy for patients admitted with acute gallbladder pathology is unclear. Some studies have shown that emergency cholecystectomy during the index admission can reduce length of hospital stay with similar rates of conversion to open surgery, complications and mortality compared with a 'delayed' operation following discharge. Others have reported that cholecystectomy during the index acute admission results in higher morbidity, extended length of stay and increased costs. This study examined the cost-effectiveness of emergency versus delayed cholecystectomy for acute benign gallbladder disease. Using data from a prospective population-based cohort study examining the outcomes of cholecystectomy in the UK and Ireland, a model-based cost-utility analysis was conducted from the perspective of the UK National Health Service, with a 1-year time horizon for costs and outcomes. Probabilistic sensitivity analysis was used to investigate the impact of parameter uncertainty on the results obtained from the model. Emergency cholecystectomy was found to be less costly (£4570 versus £4720; €5484 versus €5664) and more effective (0·8868 versus 0·8662 QALYs) than delayed cholecystectomy. Probabilistic sensitivity analysis showed that the emergency strategy is more than 60 per cent likely to be cost-effective across willingness-to-pay values for the QALY from £0 to £100 000 (€0-120 000). Emergency cholecystectomy is less costly and more effective than delayed cholecystectomy. This approach is likely to be beneficial to patients in terms of improved health outcomes and to the healthcare provider owing to the reduced costs. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

  12. Acute primary haemorrhagic omental torsion mimicking perforated appendicitis: an unorthodox surgical paradox.

    PubMed

    Rehman, Abdul

    2014-08-01

    Acute primary haemorrhagic omental torsion is an atypical and deceptive cause of acute abdomen that could closely mimic a myriad of intra-abdominal catastrophes, especially perforated appendicitis. The author reports a 30 years man who had presented with gradually worsening right-sided abdominal pain of 2 days duration. Laboratory work-up and abdominal radiographs were inconclusive. Abdominal sonography detected presence of free fluid in the pelvic cul-de-sac. Based on clinical and sonographic findings, presumptive diagnosis of perforated appendicitis was made and the patient was explored through extended Rockey-Davis incision. About 500 - 700 ml of dark-coloured blood (haemoperitoneum) was present in the peritoneal cavity and the pelvis secondary to acute haemorrhagic omental torsion. The appendix was grossly normal. Omentectomy and prophylactic appendicectomy resulted in uneventful recovery of the patient. Acute primary omental torsion is an uncommon pathology that must be kept in mind during differential diagnosis of acute abdomen, especially acute or perforated appendicitis.

    Acute appendicitis is the most common cause of acute abdomen in pediatric emergency department (ED) visits, and right lower quadrant abdominal ultrasound (RLQUS) is a valuable diagnostic tool in the clinical approach. The utility of ultrasound in predicting perforation has not been well-defined. We sought to determine the sensitivity of RLQUS to identify perforation in pediatric patients with appendicitis. A chart review of all patients 3 to 21 years of age who received a radiographic work-up and who were ultimately diagnosed with perforated appendicitis between 2010 and 2013 at a pediatric ED was conducted. The final read for ultrasonography was compared to either the operative diagnosis, surgical pathology diagnosis, or further imaging results (if the patient was managed nonoperatively). Test characteristics were calculated for the identification of appendicitis and identification of perforation. Of the 539 patients evaluated for appendicitis, 144 (26.7%) patients had appendicitis, and 40 of these (27.8%) were perforated. Thirty-nine had RLQUS performed as part of their evaluation. Of these, 28 had positive findings for appendicitis, and 9 were read as definite or possible perforated appendicitis. The sensitivity of RLQUS for the diagnosis of appendicitis in the group with perforation was 77.1% (95% confidence interval [CI], 59.4-89%) and the sensitivity for diagnosing a perforation was 23.1% (95% CI, 11.1-39.3%). There was a low rate of detection of perforation by RLQUS in our pediatric population. If larger studies confirm this, additional imaging should be recommended in patients with a high suspicion of perforation and in whom a diagnosis of perforation would change management.

    2017-01-01

    Backgrounds/Aims Frequently encountered in practice, the first-line treatment for acute cholecystitis is early or urgent cholecystectomy, with laparoscopic cholecystectomy (LC) being the preferred method. Percutaneous transhepatic gallbladder drainage (PTGBD) is considered as a safe alternative therapeutic option for resolving acute cholecystitis in surgically high-risk patients. We evaluated the surgical outcomes of acute cholecystitis, focusing on the differences between emergent LC without PTGBD, and scheduled LC following PTGBD. Methods Between March 2010 and December 2014, 294 patients with acute cholecystitis who had undergone LC, were retrospectively studied. Group I included 166 patients who underwent emergency LC without PTGBD. Group II included 128 patients who underwent scheduled LC after PTGBD. Clinical outcomes were analyzed according to each group. Results On admission, Group II had a higher mean level of c-reactive protein than Group I. According to the classification of the American Society of Anesthesiologists (ASA), group II had a greater number of high-risk patients than group I. There was no significant difference on perioperative outcomes between the two groups, including open conversion rate and complications. Analysis as per the ASA classes revealed no statistically remarkable finding between the groups. Conclusions There are no significant differences in the surgical outcomes of emergency LC group without PTGBD, and scheduled LC group following PTGBD. Comparison between two groups according to ASA classification reflecting the comorbidity and severity of condition of the patients also revealed no significant differences. However, scheduled LC following PTGBD is important for patients having acute cholecystitis with concurrent comorbidity. PMID:28317042

    Pneumoperitoneum is usually associated with gastrointestinal perforation or following surgical and endoscopic procedures. We report a rare case of spontaneously perforated pyometra presenting with generalised peritonitis and pneumoperitoneum. Perforation of the uterus is also unusual and often associated with the presence of an intrauterine device, a gravid uterus or malignancy. Our case illustrates the importance of clinical knowledge of acute and neoplastic gynaecological diseases, which are not uncommonly encountered by the general surgeon. Moreover, good appreciation of pelvic anatomy and close collaboration with gynaecology colleagues is essential as operative intervention is often required. PMID:23131215

    Massive lower gastrointestinal (GI) bleeding caused by gallbladder carcinoma eroding into the colonic wall was demonstrated accurately by Tc-99m RBCs. In addition, retrograde bleeding into the gallbladder was also identified while arteriography did not show contrast extravasation. This case supports the use of Tc-99m RBCs over Tc-99m sulfur colloid for more accurate localization of lower GI bleeding.

    Pyometra is the accumulation of pus in the uterine cavity, and spontaneous perforation of pyometra resulting in generalized diffuse peritonitis is extremely uncommon. We report a rare case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 66-year-old postmenopausal woman with diffuse abdominal pain and vomiting was admitted to our institution. She had a history of mixed connective-tissue disease and had been taking steroids for 20 years. Under a diagnosis of generalized peritonitis secondary to perforation of the gastrointestinal tract or uterus, supravaginal hysterectomy and bilateral salpingo-oophorectomy were performed. Unfortunately, wound dehiscence and infection occurred during the postoperative course, which were exacerbated by her immunocompromised state. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on the 36th postoperative day. Although correct diagnosis, early intervention, and proper treatment can reduce morbidity and mortality of spontaneous perforation of pyometra, if severe infection occurs, this disease can be life threatening for immunocompromised hosts.

    Ogilvie syndrome or acute colonic pseudo-obstruction is characterized by acute dilatation of the colon usually involving caecum and right hemi-colon in the absence of any mechanical obstruction. It is usually associated with an underlying severe illness/infection or surgery, mostly caesarean section and rarely occurs spontaneously. Identification of this condition is important due to the increased risk of bowel ischaemia and perforation particularly with caecal diameter >9 cm. This is a case report of bowel perforation following caesarean section leading to urgent laparotomy. PMID:27554827

    Palatal perforation can occur due to trauma, infection and malignancy. Mucormycosis is a rare opportunistic fungal infection caused by an organism of class zygomycetes. Rhinocerebral mucormycosis is the most common type of mucormycosis that typically starts in maxillary antrum in immunocompromised patients. Invasion of surrounding structures leads to necrotizing ulcer of the hard palate and ultimately leads to perforation. Here, we report a case of perforation of the hard palate due to mucormycosis in a eight years child having acute lymphoblastic leukemia (ALL), who was on prolonged chemotherapy and corticosteroid therapy. This case is being reported for its rarity. The aim of presenting this case report is to emphasize that the infection due to mucomycosis should be included in the differential diagnosis of hard palate perforation in ALL patients who are immunocompromised.

    Early diagnosis of perforated appendicitis is important for reducing morbidity rates. The aim of this study was to determine the value and utility of plasma D-lactic acid levels in identifying the type of appendicitis. In this clinical study, plasma D-lactic acid levels were assessed in 44 consecutive paediatric patients (23 with acute appendicitis, 21 with perforated appendicitis) before laparotomy. D-lactic acid levels were determined by an enzymatic spectrophotometric technique using a D-lactic acid dehydrogenase kit. Patients with perforated appendicitis had higher D-lactic acid levels (3.970 +/- 0.687 mg/dL) than patients in the control group (0.478 +/- 0.149 mg/dL) and patients with acute appendicitis (1.409 +/- 0.324 mg/dL; p < 0.05). For a plasma D-lactic acid level greater than 2.5 mg/dL, the sensitivity and specificity of the D-lactic acid assay were 96% and 87%, respectively. The positive predictive value was 87%, the negative predictive value was 96%, and the diagnostic value was 91%. These results suggest that the measurement of plasma D-lactic acid levels may be a useful adjunct to clinical and radiological findings in distinguishing perforated from acute non-perforated appendicitis in children.

  3. ACUTE PERFORATED APPENDICITIS IN CHILDHOOD—Analysis of Management, Including the Use of Hypothermia

    PubMed Central

    Brayton, Donald

    1956-01-01

    From an analysis of a recent series of 99 cases of acute perforated appendicitis in childhood several conclusions appeared valid. 1. The majority of infants and young children with acute perforated appendicitis do not exhibit the signs of localization of peritoneal irritation so characteristically seen in older children and adults. Hence if a history compatible with acute perforated appendicitis is present and there is evidence of peritoneal irritation on repeated examinations, patients of this age group may be assumed to have the disease and should be prepared and operated upon with minimal delay. Early operation after a maximum of several hours of preparation with parenteral hydration, nasogastric suction and antibiotics is the treatment of choice. 2. In nine patients in the present series with temperature and rapid pulse that did not fall to safe levels with the usual preoperative preparation, mild hypothermia appeared to reduce the risk of anesthesia and operation. 3. The use of intraperitoneal drains in children with acute perforated appendicitis is associated with a definite reduction in the incidence of postoperative intraperitoneal abscesses and with a probable reduction in the number of serious wound infections.

    Gastrointestinal (GI) perforation accounts for over 90% of acute abdomen and pneumoperitoneum. The presence of pneumoperitoneum secondary to spontaneously perforated pyometra is an interesting yet confusing finding given the absence of gastrointestinal (GI) perforation, because pyometra is more common in postmenopausal women. We report an instructive case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 70-year-old postmenopausal female was admitted to surgical emergency with signs of diffuse peritonitis. After resuscitation, an emergency laparotomy was performed because of suspicion of GI perforation. At laparotomy, about 2,000 mL of purulent fluid was found to be present in peritoneal cavity, while GI tract was intact. A rent with a diameter of 5 mm was found on anterior fundus of uterus. A total abdominal hysterectomy with a bilateral salpingo-oophorectomy was performed. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on postoperative day 16. Our case illustrates the importance of clinical knowledge of acute gynecological diseases, which are not uncommonly encountered by the general surgeon. Moreover, good appreciation of pelvic anatomy and close collaboration with gynecology and GI surgery colleagues is essential as operative intervention is often required. PMID:25628913

We present the classical radiological and endoscopic features and treatment strategy of a middle-aged female patient suffering from acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess, esophageal perforation, mediastinitis, and empyema. Case Report: A 60-year-old Taiwanese female presented at our hospital due to fever, fatigue, painful swallowing, and vague chest pain for 5 days. She had a past history of uncontrolled type 2 diabetes mellitus. On physical examination, general weakness, chest pain, odynophagia, and a fever up to 38.9°C were found. Positive laboratory findings included leukocytosis (leukocyte count of 14.58×103/μL, neutrophils 76.8%) and serum glucose 348 mg/dL (HbA1c 11.3%). A diagnosis of acute phlegmonous esophagogastritis with hypopharyngeal abscess was made based on typical computed tomography image features and clinical signs of infection. The patient received empirical antibiotic therapy initially; however, esophageal perforation with mediastinitis and empyema developed after admission. Emergency surgery with drainage and debridement was performed and antibiotics were administered. She was discharged in a stable condition on the 56th day of hospitalization. Six months later, a delayed esophageal reconstruction was performed. The patient has performed well for 9 months to date since the initial diagnosis. Conclusions: Acute phlegmonous esophagogastritis complicated with hypopharyngeal abscess and esophageal perforation is extremely rare, and requires immediate medical

    Gallbladder calcification, also referred to as porcelain gallbladder, has received significant attention in the medical literature due to its perceived role in increasing the risk of developing a gallbladder carcinoma. However, recent reports raise questions challenging this purported high risk. While previous studies reported a concomitant incidence of gallbladder cancer in porcelain gallbladder ranging from 7–60%, more recent analyses indicate the incidence to be much lower (6%). Based on evidence in the current literature, a prophylactic cholecystectomy is not routinely recommended for all patients with porcelain gallbladder and should be restricted to those with conventional indications, such as young patients. However, it is important to note that a nonoperative approach may require prolonged follow-up. A laparoscopic cholecystectomy is a feasible therapeutic option for patients with porcelain gallbladder, although some researchers have indicated a higher incidence of complications and conversion due to technical difficulties.

    The use of diagnostic laparoscopy in acute abdominal pain, especially when patients have been admitted for acute pain in the lower abdominal quadrants, improves the accuracy of diagnosis and leads to improvements in treatment procedures. A case is reported of a 24-year-old woman admitted under suspicion of appendicitis. The appendix was found to be normal, and a perforation caused by a fishbone was discovered in a Meckel's diverticulum. The diverticulum was resected by a combined laparoscopic and open procedure. Diagnostic laparoscopy should be performed routinely in cases of acute abdominal pain in the lower quadrants of suspected appendiceal origin to avoid overlooking other causes of the symptoms.

    Pyometra is an uncommon and potentially lethal disease that occurs mainly in postmenopausal women. Spontaneous perforation of pyometra presenting as acute abdomen is an extremely rare complication of pyometra, and the patients are always admitted to the emergency department. An additional case is reported herein. In addition, a literature review was performed between 1949 and 2015. A correct preoperative diagnosis was made in 21.05% of all the cases. Of all cases, 25.71% were associated with malignant disease. The mortality rate of spontaneous perforation of pyometra is 31.88%. Thus, it should be considered in the differential diagnosis of acute abdomen in elderly women. Total hysterectomy along with bilateral salpingo-oophorectomy is the preferred treatment. Administration of broad-spectrum antibiotics and postoperative intensive care support are essential to reduce the high mortality.

    Spontaneous extrahepatic bile duct perforation is generally seen in infants. Although rarely seen in adults, it may be seen with fatal bile peritonitis. Therefore, for a patient presenting with acute abdominal symptoms, differential diagnosis must be made with radiological imaging such as abdominal ultrasonography or computed tomography, without any loss of time. In these imaging tests, in cases of gallstone disease together with perihepatic free fluid or choledocus which can not be monitored, it should be considered in the differential diagnosis. An emergency surgical intervention should be planned to avoid serious complications. The aim of this paper was to present the rare cause of acute abdomen which developed associated with spontaneous common hepatic canal perforation in an adult.

    Gallbladder paraganglioma is a very rare tumor, and only a few cases have been reported. Most of these cases were asymptomatic and found incidentally during operation. Our case involved a 57-year-old female patient complaining of intermittent right upper quadrant pain. Preoperative imaging demonstrated a mass in the neck of the gallbladder. Laparoscopic cholecystectomy was performed, and a frozen section of the gallbladder demonstrated a benign mass. The postoperative pathologic examination reported gallbladder paraganglioma and chronic cholecystitis. Immunohistochemically, the chief cells and sustentacular cells showed diffuse positivity with vimentin, synaptophysin, and S-100.

    Gallbladder cancer is the fifth most common cancer involving gastrointestinal tract, but it is the most common malignancy of the biliary tract, accounting for 80-95% of biliary tract cancers. This tumor is a highly lethal disease with an overall 5-year survival of less than 5% and mean survival mere than 6 months. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis. The percentage of patients diagnosed to have gallbladder cancer after simple cholecystectomy for presumed gallbladder stone disease is 0.5-1.5%. Patients with preoperative suspicion of gallbladder cancer should not be treated by laparoscopy. Epidemiological studies have identified striking geographic and ethnic disparities—inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Improved imaging modalities and improved radical aggressive surgical approach in the last decade has improved outcomes and helped prolong survival in patients with gallbladder cancer. The overall 5-year survival for patients with gallbladder cancer who underwent R0 curative resection was from 21% to 69%. In the future, the development of potential diagnostic markers for disease will yield screening opportunities for those at risk either with ethnic susceptibility or known anatomic anomalies of the biliary tract.

    Infections of the gastrointestinal tract can often involve the gallbladder. Infection probably plays a role in the formation of gallstones but is more commonly thought to contribute to acute illness in patients. Acute calculous cholecystitis caused by an impacted gallstone is often complicated by secondary bacterial infection and is a major cause of morbidity and even mortality in patients. A wide variety of organisms can be associated with acute acalculous cholecystitis, a less common but potentially more severe form of acute cholecystitis. This review focuses on infections and their role in the above-mentioned processes involving the gallbladder. Copyright © 2010 Elsevier Inc. All rights reserved.

    We represent the US findings of isolated gallbladder rupture caused by blunt abdominal trauma in a 13-year-old boy. At the initial US examination, although a pericholecystic fluid collection was observed, the mildly collapsed gallbladder was regarded as a contracted gallbladder. Even though the patient was haemodynamically stable, repeat US examination after 24 h revealed gallbladder perforation. In haemodynamically stable trauma patients repeated US examinations can be useful and are strongly recommended.

  3. Carcinoma gallbladder.

    2010-07-01

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease. The diagnosis is established by ultrasonography, computerized tomography and guided fine needle aspiration cytology (FNAC). Biochemical tests are of very little value in making a diagnosis. The treatment depends on the clinical stage at presentation. Surgery offers the best chance of cure. In stage T1a, laparoscopic or open cholecystectomy alone is curative, and in T1b, cholecystectomy with hepatoduodenal lymph node dissection without combined resection of an adjacent organ is required. Segment S4a+5 hepatectomy combined with extrahepatic bile duct resection (BDR) and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 CaGb. The dye injection method is useful in determining the appropriate extent of hepatic resection for advanced CaGb. Resurgery is required only in those cases where tumour has invaded the serosa and/ or adjacent structures when diagnosed postoperatively. Biliary bypass is required for palliation. Prognosis depends on early diagnosis and appropriate surgical excision.

    Summary Background: The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the surgical acute abdomen with free intraperitoneal air. Only 38 cases have been reported worldwide. Case Report: We report 2 cases of spontaneously perforated pyometra in our hospital’s general surgery department. Both underwent exploratory laparotomy: one had a total hysterectomy and bilateral salpingo-oophorectomy, while the other had an evacuation of the uterine cavity, primary repair of uterine perforation and a peritoneal washout. A literature search was conducted and all reported cases reviewed in order to describe the clinical presentations and management of the condition. Of the 40 cases to date, including 2 of our cases, the most common presenting symptoms were abdominal pain (97.5%), fever (37.5%) and vomiting (25.0%). The main indication for exploratory laparotomy was pneumoperitoneum (97.5%). Conclusions: Pyometra is an unusual but serious condition in elderly women presenting with an acute abdomen. A high index of suspicion is needed to make the appropriate diagnosis. PMID:23569488

    Introduction: Ileal perforation peritonitis is a common surgical emergency in the Indian subcontinent and in tropical countries. It is reported to constitute the fifth common cause of abdominal emergencies due to high incidence of enteric fever and tuberculosis in these management based on Acute Physiological and Chronic Health Evaluation II (APACHE II) score. Methods: The following study was conducted in the Department of General Surgery, Government Medical College, Patiala. A total of 57 patients were studied and divided in to Group I, II, and III. APACHE II score accessed and score between 10 and 19 were blindly randomized into three procedures primary closure, resection-anastomosis, and ileostomy. The outcome was compared. Results: Ileal perforations were most commonly observed in the third and fourth decade of life with male dominance. APACHE II score was accessed and out of total 57 patients, 6 patients had APACHE II score of 0–9, 48 patients had APACHE II score of 10–19, and 3 patients had APACHE II score of ≥20. In APACHE II score 10–19, 15 patients underwent primary closure, 16 patients underwent resection-anastomosis, and 17 patients underwent ileostomy. Discussion and Conclusion: Primary closure of perforation is advocated in patients with single, small perforation (<1 cm) with APACHE II score 10–19 irrespective of duration of perforation. Ileostomy is advocated in APACHE II score 10–19, where the terminal ileum is grossly inflamed with multiple perforations, large perforations (>1 cm), fecal peritonitis, matted bowel loops, intraoperative evidence of caseating lymph nodes, strictures, and an unhealthy gut due to edema.

    AIM To establish a severe acute cholangitis (SAC) model in mice. METHODS Cholecystic catheterization was performed under the condition of bile duct ligation (BDL). Trans-cholecystic injection of lipopolysaccharide (LPS) was defined as the SAC animal model. Sham operation group, intraperitoneal injection of LPS without BDL group, intraperitoneal injection of LPS with BDL group and trans-cholecystic injection of normal saline with BDL group were defined as control groups. The survival rates and tissue injuries in liver, lungs and kidney were evaluated. RESULTS Mice in the SAC group showed a time-dependent mortality and much more severe tissue injuries in liver, lungs and kidney, compared with other groups. However, relieving biliary obstruction could effectively reduce mortality and attenuate liver injury in the SAC mouse model. CONCLUSION Trans-cholecystic injection of LPS under the condition of biliary obstruction could establish a repeatable and reversible mouse model of SAC. PMID:28348482

    Gangrenous cholecystitis and perforation are severe complications of acute cholecystitis, which have a challenging preoperative diagnosis. Early identification allows better surgical management. Contrast-enhanced computed tomography (ceCT) is the current diagnostic gold standard. Contrast-enhanced ultrasonography (CEUS) is a promising tool for the diagnosis of gallbladder perforation, but data from the literature concerning efficacy are sparse. The aim of the study was to evaluate CEUS findings in pathologically proven complicated cholecystitis (gangrenous, perforated gallbladder, pericholecystic abscess). A total of 8 patients submitted to preoperative CEUS, and with subsequent proven acute complicated cholecystitis at surgical inspection and pathological analysis, were retrospectively identified. The final diagnosis was gangrenous/phlegmonous cholecystitis (n. 2), phlegmonous/ulcerative changes plus pericholecystic abscess (n. 2), perforated plus pericholecystic abscess (n. 3), or perforated plus pericholecystic biliary collection (n. 1). Conventional US findings revealed irregularly thickened gallbladder walls in all 8 patients, with vaguely defined walls in 7 patients, four of whom also had striated wall thickening. CEUS revealed irregular enhancing gallbladder walls in all patients. A distinct wall defect was seen in six patients, confirmed as gangrenous/phlegmonous cholecystitis at pathology in all six, and in four as perforation at macroscopic surgical inspection. CEUS is a non-invasive easily repeatable technique that can be performed at the bedside, and is able to accurately diagnose complicated/perforated cholecystitis. Despite the limited sample size in the present case series, CEUS appears as a promising tool for the management of patients with the clinical possibility of having an acute complicated cholecystitis.

    To describe a patient with cone dystrophy who presented with acute hydrops and perforation, leading to the diagnosis of keratoconus. Case report and literature review. A 21 -year-old male patient with a history of cone dystrophy presented with a flat anterior chamber, diffuse corneal stromal edema with an intrastromal cleft, and ruptured Descemet membrane, findings consistent with acute hydrops with corneal perforation. After bandage contact lens placement and instillation of a cycloplegic agent, the anterior chamber reformed within 24 hours. Over the next week, conservative management with a bandage lens, pressure patching, topical fluoroquinolone antibiotic, and topical cycloplegic led to the reformation and maintenance of anterior chamber stability. Corneal topography of the unaffected eye showed global corneal thinning and steep sim K readings suspicious for early keratoconus. Although the association between keratoconus and cone dystrophy is extremely rare, our patient's vision-threatening complication of acute hydrops with corneal perforation highlights the importance of corneal evaluation including topography in cone dystrophy. Conservative management was successful in the restoration of anatomic integrity in this situation.

    Acute acalculous cholecystitis (AAC) represents a severe disease in critically ill patients. The pathogenesis of acute necroinflammatory gallbladder disease is multifactorial and intensive care unit (ICU) patients show multiple risk factors. In addition AAC is difficult to diagnose because of the vague physical and non-specific technical findings. Only the combination of clinical and technical findings including the challenging physical examination of critically ill patients, laboratory results and ultrasound or computed tomography (CT) scan, will lead to the diagnosis. The condition of AAC has a rapid progress to gallbladder necrosis, gangrene and perforation and these complications are reflected in the high morbidity and mortality rates, therefore, therapy should be promptly initiated. If there are no clinical contraindications for an operative approach cholecystectomy is the definitive treatment and both open and laparoscopic procedures have been used. In unstable, critically ill patients percutaneous cholecystostomy should be immediately performed. In addition, transpapillary endoscopic drainage is also possible if there are contraindications for percutaneous cholecystostomy. Patients who fail to improve or deteriorate following interventional drainage should be reconsidered for cholecystectomy. Due to the fact that more than 90 % of patients treated with percutaneous cholecystostomy showed no recurrence of symptoms during a period of more than 1 year, it is still unclear if percutaneous cholecystostomy is the definitive treatment of AAC for unstable patients or if delayed cholecystectomy is still necessary.

    2015-01-01

    The host-pathogen interactions occurring in the gallbladder during Salmonella Typhi colonization contribute to typhoid fever pathogenesis during the acute and chronic stages of disease. The gallbladder is the primary reservoir during chronic typhoid carriage. In this organ, Salmonella encounters host-barriers including bile, immunoglobulins, and mucus. However, the bacterium possesses mechanisms to resist and persist in this environment, in part by its ability to attach to and invade into the gallbladder epithelium. Such persistence in the gallbladder epithelium contributes to chronic carriage. In addition, patients harboring gallstones in their gallbladders have increased risk of becoming carriers because these abnormalities serve as a substrate for Salmonella biofilm formation. Our laboratory has studied the Salmonella interactions in this specific environment by developing in vitro methods that closely mimic the gallbladder and gallstones niches. These methods are reproducible and provide a platform for future studies of acute and chronic bacterial infections in the gallbladder.

    AIM To assess the long-term outcomes of this procedure after removal of self-expandable metal stent (SEMS). The efficacy and safety of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) with SEMS were also assessed. METHODS Between January 2010 and April 2015, 12 patients with acute calculous cholecystitis, who were deemed unsuitable for cholecystectomy, underwent EUS-GBD with a SEMS. EUS-GBD was performed under the guidance of EUS and fluoroscopy, by puncturing the gallbladder with a needle, inserting a guidewire, dilating the puncture hole, and placing a SEMS. The SEMS was removed and/or replaced with a 7-Fr plastic pigtail stent after cholecystitis improved. The technical and clinical success rates, adverse event rate, and recurrence rate were all measured. RESULTS The rates of technical success, clinical success, and adverse events were 100%, 100%, and 0%, respectively. After cholecystitis improved, the SEMS was removed without replacement in eight patients, whereas it was replaced with a 7-Fr pigtail stent in four patients. Recurrence was seen in one patient (8.3%) who did not receive a replacement pigtail stent. The median follow-up period after EUS-GBD was 304 d (78-1492). CONCLUSION EUS-GBD with a SEMS is a possible alternative treatment for acute cholecystitis. Long-term outcomes after removal of the SEMS were excellent. Removal of the SEMS at 4-wk after SEMS placement and improvement of symptoms might avoid migration of the stent and recurrence of cholecystitis due to food impaction. PMID:28216973

    Tympanic membrane perforations (TMP) are relatively common but are typically not treated in their acute stage, as most will heal spontaneously in 7-10 days. Those cases which fail to heal within 3 months are called chronic TMP which attract surgical intervention (e.g. myringoplasty), typically with a temporalis fascia autograft. New materials for the repair of chronic TMP are being developed to address deficiencies in the performance of autografts by undergoing evaluation in animal models prior to clinical study. However, there is currently a lack of ideal chronic TMP animal models available, hindering the development of new treatments. Various techniques and animal species have been investigated for the creation of chronic TMP with varied success. In the present commentary, we bring to the attention of readers the recent report by Shen et al. in Journal of Translational Medicine. The study reported the creation of a chronic TMP animal model in plasminogen gene deficient mice. However, the short observation time (9, 19 days), lack of success rate and the scarcity of solid evidence (e.g. otoscopic & histologic images) to confirm the chronicity of TMP warrant a more thorough discussion.

    The gallbladder serves as the repository for bile produced in the liver. However, bile within the gallbladder may become supersaturated with cholesterol, leading to crystal precipitation and subsequent gallstone formation. The most common disorders of the gallbladder are related to gallstones and include symptomatic cholelithiasis, acute and chronic cholecystitis, and carcinoma of the gallbladder. Other conditions that can affect the gallbladder include biliary dyskinesia (functional), adenomyomatosis (hyperplastic), and postoperative changes or complications (iatrogenic). Ultrasonography (US) has been the traditional modality for evaluating gallbladder disease, primarily owing to its high sensitivity and specificity for both stone disease and gallbladder inflammation. US performed before and after ingestion of a fatty meal may also be useful for functional evaluation of the gallbladder. However, US is limited by patient body habitus, with degradation of image quality and anatomic detail in obese individuals. With the advent of faster and more efficient imaging techniques, magnetic resonance (MR) imaging has assumed an increasing role as an adjunct modality for gallbladder imaging, primarily in patients who are incompletely assessed with US. MR imaging allows simultaneous anatomic and physiologic assessment of the gallbladder and biliary tract in both initial evaluation of disease and examination of the postoperative patient. This assessment is accomplished chiefly through the use of MR imaging contrast agents excreted preferentially via the biliary system.

All the histological slides for the cancer group were reviewed and reclassified by a single pathologist. Of 4502 cholecystectomies performed, 33 cases (0.73%) of gallbladder carcinoma were found. The mean age was 61.4 years (range 39-80 years). The male : female ratio was 1 : 3.7. Biliary colic and/or acute cholecystitis were the main presentations. Gallstones were present in 88% (29/33) of the patients. The spectrum of histological subtypes was similar to other series. Only three cases were diagnosed preoperatively, making the incidence of incidental gallbladder cancer 0.66% (30/4502). Simple cholecystectomy was performed for 13 patients. The remaining 20 patients underwent cholecystectomy and portal lymphadenectomy with (five cases) or without (15 cases) extrahepatic resection of the bile ducts. The mean follow up was 22 months (SD +/- 18.95 months; range 1-96 months). The 2-year survival rates for stages I, II, III, and IV were 100%, 42.9%, 10.8%, and 0%, respectively (P = 0.0013). The importance of a high index of suspicion when dealing with cholelithiasis in elderly patients, particularly with large sized stones, cannot be over-emphasized. Proper gross inspection in the theater should be a routine procedure performed by all surgeons. Routine ultrasound for suspected gallbladder stones should always be performed under the supervision of senior radiologists.

  11. Esophagus perforation and myocardial penetration caused by swallowing of a foreign body leading to a misdiagnosis of acute coronary syndrome: a case report.

    Here we present our clinical experience in a case of esophagus perforation due to the swallowing of a bone piece causing acute angina pectoris and leading to misdiagnosis of acute coronary syndrome. A 73-year-old Caucasian man underwent urgent coronary angiography with possible diagnosis of acute coronary syndrome. His coronary arteries were found to be normal. A computed tomography examination revealed esophagus perforation by a foreign body (a piece of bone), and he underwent urgent left thoracotomy and the foreign body was removed. Sometimes, even a piece of bone within a meal can lead to esophagus perforation, and injure the pericardium and myocardium. The symptoms of esophagus perforation may be confused with acute coronary syndrome due to their similarities and lack of knowledge about the detailed clinical history as shown in our case. Thus, careful consideration of detailed clinical history as well as choosing an appropriate medical imaging modality, such as computed tomography, should always be kept in mind in order to promptly diagnose and start early treatment to reduce mortality.

    Gallbladder infarction developing after transcatheter arterial embolization (TAE) in patients with malignant hepatic tumors was studied by comparing preoperative angiographic and postoperative macroscopic and histological findings. Eight patients demonstrated occlusion of the cystic artery or its branches by embolic materials on post-TAE angiograms. Surgery revealed infarction of the gallbladder in 6 patients; no infarction was noted in the other 2, although branches of the cystic artery were occluded on the post-TAE angiogram. Due to recanalization of the occluded artery, the infarcted area could be assessed only by follow-up angiography. No patient experienced perforation of the gallbladder as a result of infarction. The authors suggest that patients with post-TAE infarction of the gallbladder can be treated consevatively if they are kept under close observation.

    Abstract Background The ablation of liver tumors located close to the gallbladder is likely to lead to complications. The aim of this article is to compare the safety and efficacy of irreversible electroporation (IRE) and cryoablation in rabbit livers at a location close to the gallbladder. Materials and methods We performed cryoablation (n = 12) and IRE (n = 12) of the area of the liver close to the gallbladder in 24 New Zealand white rabbits in order to ensure gallbladder damage. Serum aminotransferase and serum bilirubin levels were measured before and after the ablation. Histopathological examination of the ablation zones in the liver and gallbladder was performed on the 7th day after the ablation. Result Seven days after the ablation, all 24 animals were alive. Gallbladder perforation did not occur in the IRE group; only mucosal epithelial necrosis and serous layer edema were found in this group. Gallbladder perforation occurred in four rabbits in the cryoablation group. Serum aminotransferase and serum bilirubin levels obviously increased in both groups by Day 3 and decreased gradually thereafter. The elevation in aminotransferase and bilirubin levels was greater in the cryoablation group than the IRE group. Pathological examination revealed complete necrosis of the liver parenchyma from the ablation center to the gallbladder in both groups, but bile duct and granulation tissue hyperplasia were observed in only the IRE group. Full-thickness gallbladder-wall necrosis was seen in the cryoablation group. Conclusions For ablation of the liver area near the gallbladder, IRE is superior to cryoablation, both in terms of safety (no gallbladder perforation in the IRE group) and efficacy (complete necrosis and rapid recovery in the IRE group).

    Acute acalculous cholecystitis has a high mortality rate due to the difficulties in early diagnosis and high rate of complications like empyema, gangrene and perforation. We report a case of 20-year-old male with acute severe pancreatitis, acute renal failure and acute peripancreatic fluid collection who was transferred to our department after blood filtration treatment in ICU. After percutaneous catheter drainage for 20 hours, the patient got a high fever. Computed tomography revealed retroperitoneal colon injury. In this case, percutaneous catheter drainage was performed again and the pus cavity was flushed regularly, after which the patient’s state gradually improved. Unpredictably, septic shock appeared on the 51st day. Repeated computed tomography revealed acute acalculous cholecystitis and abscess formation. After percutaneous transhepatic gallbladder catheterization and drainage, the patient got better gradually. Three months later the retroperitoneal catheter was removed. Four months later, ultrasound examination showed normal gallbladder and the catheter was removed. PMID:26131252

    INTRODUCTION Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment options. METHOD Based on this better understanding, the histological alterations (such as acute cholecystitis, adenomyomatosis, xanthogranulomatous cholecystitis, polyps, pyloric metaplasia, intestinal metaplasia, dysplasia, cancer and others) in gallbladders from 1,689 patients who underwent laparoscopic cholecystectomy for cholecystolithiasis were analyzed. The association of these gallbladder histological alterations with clinical data was studied. RESULTS Gender analysis revealed a greater incidence of inflammatory changes in males, while dysplasia and cancer were only found in women. The incidence of cholesterolosis was greater in the patients 60 years of age and under, and the incidence of adenomyomatosis and gangrene was greater in the elderly patients. A progressive increase in the average age was observed as alterations progressed through pyloric metaplasia, intestinal metaplasia, dysplasia and then cancer, suggesting that the metaplasia-dysplasia-carcinoma sequence may occur in gallbladder cancer. Gallbladder histological alterations were also observed in asymptomatic patients. CONCLUSION The results of this study suggest that there could be an association between some histological alterations of gallbladder and cancer, and they also suggest that the metaplasia-dysplasia-carcinoma sequence could in fact be true in the case of gallbladder cancer. Nevertheless, further studies directed towards a perfect understanding of gallbladder carcinogenesis are required. PMID:20186297

    There continues to be controversy about the necessity of interval appendectomy for delayed presentation of acute appendicitis. While recent studies suggest that the risk of recurrent disease is small, the risk of interval appendectomy is also small and does provide histologic identification and usually definitive treatment of the right lower quadrant inflammatory process. A retrospective analysis of medical records gathered from 2002 to 2007 at a major teaching hospital of 986 adult patients over the age of 13 with appendicitis were analyzed. Forty-six patients (5%) were found to have right lower quadrant abscess or phlegmon, and were managed with intravenous antibiotics. Some patients also underwent percutaneous drainage. These patients were then readmitted 6 to 26 wk later for an elective laparoscopic interval appendectomy. There were 19 males and 27 females with an average age of 43 y. Ninety-four percent of the appendectomies were completed laparoscopically; 16% of patients were found to have a normal or obliterated appendix on pathologic evaluation and likely did not benefit from interval appendectomy. On the other hand, 84% of patients had persistent acute appendicitis, chronic appendicitis, evidence of inflammatory bowel disease, or neoplasm identified, and likely benefited from surgical appendectomy. Interval appendectomy provides diagnostic and therapeutic benefit to patients who present with a right lower quadrant abdominal inflammatory focus, and should be carefully considered in all adult patients.

    Technetium-99m-labeled iminodiacetic acid (HIDA) and paraisopropyliminodiacetic acid (PIPIDA) scintigraphy after sonographic evaluation of the gallbladder have been advocated recently for the diagnosis of acute obstructive cholecystitis and cholelithiasis. Several authors have stated or inferred that gallbladder visualization with /sup 99m/Tc-HIDA excludes acute cholecystitis and cystic duct obstruction. We describe a patient with surgically proven cystic duct obstruction whose gallbladder visualized on a /sup 99m/Tc-HIDA scan via an accessory hepatic duct which directly entered the gallbladder.

    This is an unusual case in comparison to other sonographically described prenatal cases due to very early diagnosis and surgical intervention following prompt delivery. A 40-year-old pregnant, ultrasonography showed presence of cystic structure in the fetal abdomen that was consistent with intestinal dilatation. At 32 weeks' of gestation, repeat ultrasound showed collapse of the bowel dilatation along with the presence of hyperechogenic fluid in the fetal abdominal cavity. Cesarean section was performed. The clinical utility of this report is the recognition that meconium peritonitis (MP) may be diagnosed in the acute phase with typical ultrasound features, and should be considered in the differential diagnoses of cases presented with reduced fetal movements. Although it appears that morbidity and mortality in MP cases depend upon gestational age, this case report may help to manage similar cases for defining the appropriate delivery time and treatment modality after prenatal identification of the problem.

    Pyometra is collection of purulent material which occurs when there is interference with its normal drainage. It is an uncommon condition with incidence of 0.1 to 0.5% of all gynecological patients. Spontaneous rupture of uterus is an extremely rare complication of pyometra. A 65-year-old lady presented with pain abdomen and purulent vaginal discharge. Preoperative diagnosis of pyometra was made by magnetic resonance imaging (MRI). Laparotomy followed by peritoneal lavage and repair of perforation was performed. Although spontaneously perforated pyometra is rare, the condition must be borne in mind with regard to elderly women with acute abdominal pain. Preoperative diagnosis of perforated pyometra is absolutely essential. Computed tomography (CT) and MRI are diagnostic tools. In selected cases conservative approach at surgery can be opted.

    A 34-year-old man who had been referred to our hospital was diagnosed with acute promyelocytic leukemia (APL). All-trans retinoic acid (ATRA), oral administration, was initiated. On day 25, he developed fever and respiratory distress with bilateral pulmonary infiltrates, suggesting differentiation syndrome (DS) caused by ATRA. These symptoms showed amelioration after discontinuing ATRA and initiating methylprednisolone. ATRA was re-started on day 29 at half the original dose because of residual APL blasts. The patient subsequently developed fever, severe stomatitis, and oropharyngeal ulcers, which persisted even after discontinuing ATRA. On day 48, he suddenly developed severe abdominal pain with free air, observable on an abdominal X-ray, and underwent emergency ileocecal resection. Pathological examination of the resected ileocecal intestines revealed multiple ulcers and perforations. No leukemic cell infiltration was observed. In this case, only ATRA was administered for APL treatment. These findings suggest that ileocecal ulcerations and perforations, as well as oropharyngeal ulcers, might have been caused by DS or ATRA. Furthermore, DNA typing of the HLA-B locus revealed that the patient had HLA-B51 associated with Behçet's disease. Therefore, hypercytokinemia with DS might have induced Behçet's disease-like symptoms, including stomatitis and ileocecal perforation, complications that are particularly observed in patients with HLA-B51.

    Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen. Copyright © 2016. Published by Elsevier GmbH.

  10. How to image the gallbladder in suspected cholecystitis

    Marton, K.I.; Doubilet, P.

    1988-11-01

    As a result of important advances in medical imaging, the oral cholecystogram is no longer the primary test of gallbladder function and anatomy. Real-time ultrasonography and cholescintigraphy, both highly sensitive and specific tests, are the two major methods for assessing gallbladder pathology. Oral cholecystography, endoscopic retrograde pancreatography, and percutaneous gallbladder puncture serve as supplementary tests. Decisions about which test to use depend on the kind of gallbladder disease that is suspected as well as the estimated likelihood of the disease before the information is obtained from the procedure. Thus, ultrasonography is the test of choice for chronic cholecystitis, with oral cholecystography reserved for situations in which the diagnosis is uncertain after ultrasonography. When acute cholecystitis is suspected, ultrasonography is also the test of choice in most patients, and cholescintigraphy is used to resolve uncertainty. 103 references.

    We report a case of torsion of the gallbladder displaced under the right subphrenic space in a patient with liver cirrhosis. An 82-year-old Japanese woman was admitted to our hospital for acute pain in the right upper quadrant. Clinical features suggested gallbladder torsion. She was under treatment for hepatitis C virus-related cirrhosis at our hospital. Abdominal CT showed the swollen fundus and body of the gallbladder under the right subphrenic space. Emergency laparoscopic cholecystectomy was performed. Intraoperative findings included a grossly necrotic gallbladder in the right subphrenic space with 360° clockwise torsion, together with liver cirrhosis and localized peritonitis. The clinical features and imaging findings in this rare case of misplaced gallbladder in right subphrenic space resembled those described in typical strangulated gallbladder. The displacement was probably related to right liver lobe atrophy associated with liver cirrhosis. Appropriate diagnosis and prompt surgical treatment are essential for a positive outcome.

    GB-SV was higher than in GB-SOV (35.5% vs 10%; p = 0.05). Nongranulomatous inflammation with fibrinoid necrosis of medium-sized vessels occurred equally in both groups (>90%). Forms of SV affecting the gallbladder included polyarteritis nodosa (n = 10), hepatitis B virus-associated vasculitis (n = 8), cryoglobulinemic (essential or hepatitis C virus-associated) vasculitis (n = 6), vasculitis associated with autoimmune diseases (n = 6), microscopic polyangiitis (n = 4), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (n = 4), IgA vasculitis (Henoch-Schönlein) (n = 2), and giant cell arteritis (n = 1). GV is uncommon. Its histology most often consists of a nongranulomatous necrotizing vasculitis affecting medium-sized vessels. GB-SOV is usually discovered after routine cholecystectomy performed because of the presence of local symptoms, gallstone-associated cholecystitis, and contrary to GB-SV, GB-SOV is usually not associated with systemic symptoms. Acute phase reactants and surrogate markers of autoimmunity are usually normal or negative in GB-SOV. GB-SOV does not require systemic antiinflammatory or immunosuppressive therapy; surgery is adequate to achieve cure. GB-SV always warrants immunosuppressant therapy and is associated with high mortality. The finding of GV may precede the generalized manifestations of SV. Therefore, once GV is discovered, studies to determine disease extent and a vigilant follow-up are mandatory. PMID:25500710

    Gallbladder perforation with hemorrhage may be the source of massive hemoperitoneum under rare and extreme circumstances. In cirrhotic patients the bleeding may be associated with the tearing of gallbladder varices and represents a fatal complication, as reported in all the cases available in literature. The incidence of gallbladder varices in the setting of portal hypertension ranges 12-30%, although literature data are limited. We describe the case of an end-stage cirrhotic patient without portal thrombosis awaiting for orthotopic liver transplantation, who developed a fatal hemoperitoneum caused by massive bleeding from ruptured varices of both gallbladder wall and cholecystic fossa. The review of the literature was also performed. Cirrhosis, Gallbladder, Hemoperitoneum, Perforation, Portal hypertension, Varices.

    The differentiation between osteomyelitis and bone tumor may be difficult due to their overlapping clinical and radiological features. A 25-year-old lady presented with left knee pain and joint effusion associated with redness and hotness. A sub-optimally taken plain radiograph showed mixed osteolytic and osteoblastic lesion in the left lower femur with surrounding soft tissue swelling. Since the clinical diagnosis was acute osteomyelitis and arthritis, arthroscopic lavage was performed as a diagnostic and therapeutic procedure. The removed loose bodies and fibrinous tissue showed pathological features suspicious of chondrosarcoma. Subsequent MRI revealed an infiltrative tumor eroding through the cortex and joint cartilage. En bloc excision of the left lower femur, upper tibia including the knee joint and patella was performed, and the final diagnosis was grade 2 chondrosarcoma. The patient developed bilateral pulmonary metastasis 33 months after operation. Five months later, she suffered from a hitherto undescribed complication of ischemic perforation of the terminal ileum secondary to tumor embolic arterial obstruction with no macroscopic intestinal or peritoneal tumor deposit. The patient developed multiple brain metastases and died 43 months after initial presentation. Our case illustrates that malignant bone tumor as a differential diagnosis of acute osteomyelitis and arthritis merits recognition and exclusion before arthroscopic lavage, which may enhance tumor dissemination and in our patient results in embolic ischemic ileal perforation.

    Ingested foreign bodies tend to pass through the gastrointestinal tract without incidence, and vast majority of cases do not need intervention. Rarely, these foreign bodies drop into the appendix and not likely to re-enter the normal digestive tract. We describe a case of a 72-year-old male patient who presented with right iliac fossa pain of 3-day duration. Clinical examination suggested classic acute appendicitis. Blood test results revealed leukocytosis. Computed tomography of the abdomen and pelvis showed evidence of acute appendicitis and a linear hyperdensity (foreign body) perforating the appendix. The patient was managed successfully with prompt laparoscopic appendectomy and removal of the foreign body which was confirmed to be a fish bone measuring about 10mm. While imaging diagnosis of fishbone in the appendix has been published, reports are few. To the best of the author's knowledge, fishbone induced perforated appendicitis has been described only in 2 cases (including this case) in the literature.

    In acute stage of virus hepatitis B patients often complain of dyspeptic discomfort. They may be a consequence of alimentary tract motor activity disorders including these of gallbladder. Routine ultrasonography in an early phase of virus hepatitis often reveals gallbladder wall thickening what may confirm the above thesis. Thus, a group of 15 patients in an acute phase of virus hepatitis B was subjected to examinations. Gallbladder motor activity was assessed by ultrasonographic method determining its total volume and ejection fraction and volume after test meal stimulus. First examination was performed in the first week since the appearance of yellowing of the walls, successive in 4 and 8 week of the disease. Obtained results were compared to the values obtained in the group of 25 healthy volunteers. It was found out that gallbladder volume was significantly decreased and ejection fraction increased in the acute phase of virus hepatitis B than in the controls. This may speak for gallbladder hyperreactivity in patients in the course of virus hepatitis B. These disorders decreased during two-month observation but even in the 8 week the investigated parameters differed from those found in the control group.

    Chile has the world's highest rate of incidence as well as death from cancer of the gallbladder and biliary ducts. The problem is most acute in the southern provinces. These areas constitute the low average income associated with low educational attainment and a high rate of obesity compared with the rest of Chile. We could also include genetic factors related to processes of lithogenesis to these elements which are more common among the Mapuche. This population sub-group could benefit from special government programmes for early diagnosis and treatment of lithiasic disease and for the management of risk factors such as obesity. In this way, we could reduce the mortality rate of gallbladder cancer.

    Xanthogranulomatous cholecystitis is an unusual inflammatory disease of the gallbladder characterized by severe proliferative fibrosis and the accumulation of lipid-laden macrophages in areas of destructive inflammation. Its macroscopic appearance may occasionally be confused with gallbladder carcinoma. We present a case of perforated xanthogranulomatous cholecystitis presenting as biloma. An 80-year-old woman was referred to our hospital with a 1-week history of abdominal pain and febrile sensation. Abdominal CT showed a biloma in the subhepatic area. The follow-up CT showed that the biloma increased in size. Therefore, ultrasonography-guided aspiration was performed. The aspirated fluid/serum bilirubin ratio was greater than 5, which was strongly suggestive of bile leakage complicated by perforated cholecystitis. She underwent a laparoscopic cholecystectomy with cyst aspiration and adhesiolysis. A histological diagnosis of perforated xanthogranulomatous cholecystitis was made.

    Biliary disease in children has changed over the past few decades, with a marked rise in incidence-perhaps most related to the parallel rise in pediatric obesity-as well as a rise in cholecystectomy rates. In addition to stone disease (cholelithiasis), acalculous causes of gallbladder pain such as biliary dyskinesia, also appear to be on the rise and present diagnostic and treatment conundrums to surgeons.

    Small bowel perforation is an emergent medical condition for which the diagnosis is usually not made clinically but by CT, a common imaging modality used for the diagnosis of acute abdomen. Direct CT features that suggest perforation include extraluminal air and oral contrast, which are often associated with secondary CT signs of bowel pathology. This pictorial review illustrates the CT findings of small bowel perforation caused by various clinical entities.

    Gallstone ileus is a well-established phenomenon in which a large gallstone leads to mechanical small bowel obstruction. This case, however, reports the novel finding of a patient presenting with suprapubic pain and guarding caused by paralytic ileus of the small bowel and a duodenal perforation secondary to a necrotic gallbladder. It highlights the importance of distinguishing between gallstone ileus and paralytic ileus and how the management of the two conditions differs. Furthermore, this article discusses how paralytic ileus caused by intra-abdominal inflammatory conditions such as cholecystitis can mask the typical clinical findings making the diagnosis difficult.

    Acute cholecystitis is associated with increased gallbladder prostanoid formation and the inflammatory changes and prostanoid increases can be inhibited by nonsteroidal anti-inflammatory agents. Recent information indicates that prostanoids are produced by two cyclooxygenase (COX) enzymes, COX-1 and COX-2. The purpose of this study was to determine the COX enzymatic pathway in gallbladder mucosal cells involved in the production of prostanoids stimulated by inflammatory agents. Human gallbladder mucosal cells were isolated from cholecystectomy specimens and maintained in cell culture and studied in comparison with cells from a well differentiated gallbladder mucosal carcinoma cell line. COX enzymes were evaluated by Western immunoblotting and prostanoids were measured by ELISA. Unstimulated and stimulated cells were exposed to specific COX-1 and COX-2 inhibitors. In both normal and transformed cells constitutive COX-1 was evident and in gallbladder cancer cells lysophosphatidyl choline (LPC) induced the formation of constitutive COX-1 enzyme. While not detected in unstimulated normal mucosal cells and cancer cells, COX-2 protein was induced by both lipopolysaccharide (LPS) and LPC. Unstimulated gallbladder mucosal cells and cancer cells produced prostaglandin E2 (PGE2) and prostacyclin (6-keto prostaglandin F1alpha, 6-keto PGF1alpha) continuously. In freshly isolated normal gallbladder mucosal cells, continuously produced 6 keto PGF1alpha was inhibited by both COX-1 and COX-2 inhibitors while PGE2 levels were not affected. Both LPS and LPC stimulated PGE2 and 6 keto PGF1alpha formation were blocked by COX-2 inhibitors in freshly isolated, normal human gallbladder mucosal cells and in the gallbladder cancer cells. The prostanoid response of gallbladder cells stimulated by proinflammatory agents is inhibited by COX-2 inhibitors suggesting that these agents may be effective in treating the pain and inflammation of gallbladder disease.

    This study aimed to evaluate the radiologist's ability to identify excreted gadoxetate disodium within the gallbladder on CT scan. Thirty three healthy adults underwent imaging of the liver during work-up for potential liver donation. Three patients had undergone prior cholecystectomy and therefore were excluded. Imaging consisted of gadoxetate disodium-enhanced magnetic resonance cholangiography (MRC) and multiphase contrast-enhanced CT scan of the abdomen and pelvis. Two fellowship-trained abdominal imaging radiologists, who were blinded to the MRC images and the contrast agent used during MRC, independently reviewed the CT scans of the 30 patients that were included. The scans were evaluated for the presence or absence of abnormal hyperdensity within the gallbladder. Three patients did not receive intravenous gadoxetate disodium, 4 patients had their MRC after the CT scan, and 1 patient had the CT scans 5 days following the MRC. Twenty two patients had the CT scan within 24 h following the gadoxetate disodium-enhanced MRC. Of the 22 patients expected to have gadolinium in the gallbladder, both reviewers identified hyperdensity in the same 20 patients (90%). Both reviewers reported no abnormal hyperdensity within the gallbladder in the remaining 10 patients. CT scan can reveal excreted gadoxetate disodium within the gallbladder lumen and therefore gadoxetate disodium-enhanced CT scan can potentially play a role in the evaluation of cystic duct patency and work-up of acute cholecystitis.

    To report a series of complications related to anterior cervical surgery in the same patient. There have been many reports of complications related to anterior cervical surgeries. These include cervical hematoma, instrumentation extrusion, or esophageal injury after anterior cervical decompression. However, there have been no reports of all these complications occurring in 1 patient. This is our report of a patient who experienced all 3 of these complications. The patient was a 73-year-old man suffering from cervical spondylotic myelopathy who was treated with C5 anterior cervical corpectomy and fusion with titanium mesh and bone graft. The patient successively experienced cervical hematoma, screw pullout, and esophageal perforation, and was treated accordingly. Although the patient suffered a series of complications after anterior cervical corpectomy, all the complications were treated successfully. It serves as a caution that a first complication such as hematoma in anterior cervical corpectomy with fusion should be given enough attention to prevent further complications. PMID:25692439

    Selective approach for sending cholecystectomy specimens for histopathology results in missing discrete pathologies such as premalignant benign lesions such as porcelain gallbladder, carcinoma-in-situ, and early carcinomas. To avoid such blunders therefore, every cholecystectomy specimen should be routinely examined histologically. Unfortunately, the practice of discarding gallbladder specimen is standard in most tertiary care hospitals of Pakistan including the primary investigators' own institution. This study was conducted to assess the feasibility or otherwise of performing histopathology in every specimen of gallbladder. This cohort study included 220 patients with gallstones for cholecystectomy. All cases with known secondaries from gallbladder, local invasion from other viscera, traumatic rupture of gallbladder, gross malignancy of gallbladder found during surgery was excluded from the study. Laparoscopic cholecystectomy was performed in majority of cases except in those cases where anatomical distortion and dense adhesions prevented laparoscopy. All gallbladder specimens were sent for histopathology, irrespective of their gross appearance. Over a period of two years, 220 patients with symptomatic gallstones were admitted for cholecystectomy. Most of the patients were females (88%). Ninety two per cent patients presented with upper abdominal pain of varying duration. All specimens were sent for histopathology. Two hundred and three of the specimens showed evidence chronic cholecystitis, 7 acute cholecystitis with mucocele, 3 acute cholecystitis with empyema and one chronic cholecystitis associated with poly. Six gallbladders (2.8%) showed adenocarcinoma of varying differentiation along with cholelithiasis. The histopathological spectrum of gallbladder is extremely variable. Incidental diagnosis of carcinoma gall bladder is not rare; if the protocol of routine histopathology of all gallbladder specimens is not followed, subclinical malignancies would fail to

    Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy

    Inflammation of the gallbladder without evidence of calculi is known as acute acalculous cholecystitis (AAC). AAC is frequently associated with gangrene, perforation, and empyema. Due to these associated complications, AAC can be associated with high morbidity and mortality. Medical or surgical treatments can be chosen according to the general condition of the patient, underlying disease and agent. Particularly in acute acalculous cholecystitis cases, early diagnosis and early medical treatment have a positive effect on the patient and protect them from surgical trauma. ACC is a rare complication of acute viral hepatitis A. Herein, we present an adult patient of acalculous cholecystitis due to acute viral hepatitis A. She responded to the conservative management.

    Gallbladder emptying and filling was studied in eight diabetic and six normal control patients. None of the patients had gallstones. Cholescintigraphy was performed using (/sup 99m/Tc)disofenin, and gallbladder emptying was studied using a 45-min i.v. infusion of the octapeptide of cholecystokinin (OP-CCK) 20 ng/kg X hr. The peak filling rate was greater in diabetic than in normal subjects; however, emptying of the gallbladder in response to OP-CCK was significantly less in the diabetic subjects (51.6 +/- 10.4% compared with 77.2 +/- 4.9%). When the diabetic group was subdivided into obese and nonobese diabetics, the obese diabetics had a much lower percentage of emptying than the nonobese diabetics (30.0 +/- 10.4% compared with 73.1 +/- 9.3%). These findings suggest that obese diabetics may have impaired emptying of the gallbladder even in the absence of gallstones. The more rapid rate of gallbladder filling in obesity may indicate hypotonicity of the gallbladder. The combination of these abnormalities may predispose the obese diabetic to the development of gallstones.

    Goal of this research program is to create ultrathin organic membranes that possess uniform and adjustable pores ( < 7[angstrom] diameter). Such membranes are expected to possess high permeation selectivity (permselectivity) and high permeability, and to provide the basis for energy-efficient methods of molecular separation. Work carried out has demonstrated feasibility of using perforated monolayer''-based composites as molecular sieve membranes. Specifically, composite membranes derived from Langmuir-Blodgett multilayers of the calix[6]arene-based surfactant shown below plus poly[l-(trimethylsilyl)-l-propyne] (PTMSP) were found to exhibit sieving behavior towards He, N[sub 2] and SF[sub 6].

    Ingested foreign bodies tend to pass through the gastrointestinal tract without incidence, and vast majority of cases do not need intervention. Rarely, these foreign bodies drop into the appendix and not likely to re-enter the normal digestive tract. We describe a case of a 72-year-old male patient who presented with right iliac fossa pain of 3-day duration. Clinical examination suggested classic acute appendicitis. Blood test results revealed leukocytosis. Computed tomography of the abdomen and pelvis showed evidence of acute appendicitis and a linear hyperdensity (foreign body) perforating the appendix. The patient was managed successfully with prompt laparoscopic appendectomy and removal of the foreign body which was confirmed to be a fish bone measuring about 10mm. While imaging diagnosis of fishbone in the appendix has been published, reports are few. To the best of the author’s knowledge, fishbone induced perforated appendicitis has been described only in 2 cases (including this case) in the literature. PMID:27761185

    The aim of the present study was to investigate the diagnostic value of diffusion-weighted magnetic resonance imaging in gallbladder malignancies, which are typically diagnosed during surgery because the radiologic findings are similar to those of cholecystitis-caused diffuse thickening of the gallbladder wall. Seven patients with gallbladder malignancies and nine patients with benign gallbladder pathology were included in this study. In one of the patients with a malignancy, a lesion was determined on the porcelain gallbladder; in another patient, acute myeloblastic leukemia had infiltrated the gallbladder, causing the diffuse wall thickening. Five subjects had a primary malignant gallbladder. The view of the bladder wall was evaluated visually in increasing b values. Apparent diffusion coefficient measurements were obtained from at least three sites of the bladder wall in each patient, and the results of the measurements were analyzed after comparing the malignant and benign groups. In the malignant group, the results of the radiological outcomes were compared with histological examinations. In the benign group, cholecystitis was diagnosed by observing normalization of the bladder wall thickening via surgery or medical treatment. There was a statistically significant difference in apparent diffusion coefficient levels between the malignant group, which caused diffuse thickening of the gallbladder wall, and the benign group (Student t test, p<0.01). According to this preliminary study, observation of distinct brightness of the gallbladder wall in diffusion-weighted examination with a high b value is a significant finding in terms of diffuse gallbladder malignancy. A value below the 0.86 mm 2 /sn cut-off was significant for malignancy in apparent diffusion coefficient mapping.

    The pathophysiology of canine gallbladder diseases, including biliary sludge, gallbladder mucoceles and gallstones, is poorly understood. This study aimed to evaluate the component of gallbladder contents and bacterial infection of the gallbladder in order to elucidate the pathophysiology of biliary sludge and gallbladder mucoceles. A total of 43 samples of canine gallbladder contents (biliary sludge, 21 and gallbladder mucoceles, 22) were subjected to component analysis by infrared spectroscopy, and the resultant infrared spectra were compared with that of swine mucin. Of the 43 samples, 41 were also evaluated by aerobic and anaerobic bacterial culture. The contents of 20 (95.2%) biliary sludge and 22 (100%) gallbladder mucocele samples exhibited similar infrared spectra as swine mucin. Although biliary sludge and gallbladder mucocele contents exhibited similar infrared spectra, one sample of biliary sludge (4.8%) was determined to be composed of proteins. The rate of bacterial infection of the gallbladder was 10.0% for biliary sludge and 14.3% for gallbladder mucoceles. Almost all of the identified bacterial species were intestinal flora. These results indicate that the principal components of gallbladder contents in both gallbladder mucoceles and biliary sludge are mucins and that both pathophysiologies exhibit low rates of bacterial infection of the gallbladder. Therefore, it is possible that gallbladder mucoceles and biliary sludge have the same pathophysiology, and, rather than being independent diseases, they could possibly represent a continuous disease. Thus, biliary sludge could be considered as the stage preceding the appearance of gallbladder mucoceles. PMID:27990011

    PubMed

    Turumin, J L; Shanturov, V A; Turumina, H E

    2013-01-01

    The basic function of the gallbladder in humans is one of protection. The accumulation of the primary bile acids (cholic acid and chenodeoxycholic acid) in the gallbladder reduces the formation of the secondary bile acids (deoxycholic acid and lithocholic acid), thus diminishing their concentration in the so-called gallbladder-independent enterohepatic circulation and protecting the liver, the stomach mucosa, the gallbladder, and the colon from their toxic hydrophobic effects. The presence or absence of the gallbladder in mammals is a determining factor in the synthesis of hydrophobic or hydrophilic bile acids. Because the gallbladder contracts 5-20 min after food is in the stomach and the "gastric chyme" moves from the stomach to the duodenum 1-3 h later, the function of the gallbladder bile in digestion may be insignificant. The aim of this article was to provide a detailed review of the role of the gallbladder and the mechanisms related to bile formation in humans.

    The purpose of this study was to examine whether acute non-perforated appendicitis (ANPA) can be safely triaged by a pediatrician for conservative management (CM) using gray-scale ultrasonography with power Doppler (GSPD). Seventy five cases of ANPA assessed by a pediatrician with GSPD (2013-2015) were reviewed. GSPD grading for ANPA was: I: slightly irregular wall/normal blood flow; II: irregular wall/increased blood flow; III: irregular wall/decreased blood flow; and IV: absence of wall/blood flow. Grades I/II were managed conservatively with intravenous antibiotics then encouraged to book for interval appendectomy (IA). Grades III/IV were reviewed for emergency appendectomy (EA) by a pediatric surgeon. GSPD grading was I (n=26), II (n=36), III (n=9), and IV (n=4). EA was required for 5 cases, one grade III, and four grade IV cases. One grade IV case was treated conservatively after surgical review but EA was unavoidable. Of the remaining 70 cases discharged well after a mean of 5.7days hospitalization, 25/70 had IA with chronic inflammation on histology, 6/70 had recurrence of ANPA treated successfully by EA, and 39/70 remain asymptomatic at least 10months after declining IA. Overall, GSPD triaging with CM was cheaper than surgery. GSPD performed by pediatricians appears to be safe/effective for triaging ANPA. Level III. Copyright © 2016 Elsevier Inc.

    Introduction. We report the management of a septic Open Abdomen (OA) patient by the help of negative pressure therapy (NPT) and abdominal reapproximation anchor (ABRA) system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S) with confounding factor of mild acute pancreatitis (AP). Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR). There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU) with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF) to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient. PMID:27006853

    The purpose of this article is to illustrate and discuss the various etiologies of perforation of the mesenteric small bowel and associated findings on abdominal CT. Perforation of the mesenteric small bowel is an uncommon cause of an acute abdomen and can be due to various etiologies. In underdeveloped countries, infection is probably the most common cause, while in industrialized nations, perforation may be due to Crohn disease, diverticulitis, foreign body, trauma, tumor, mechanical obstruction, primary ischemic event, or iatrogenic causes. CT is usually the initial imaging examination in patients with an acute abdomen and is sensitive in diagnosing small bowel perforation. CT findings in the setting of small bowel perforation are often subtle, but when present, may help the radiologist determine a specific cause of perforation. The aims of this pictorial essay are to review the various causes of mesenteric small bowel perforation and to discuss and illustrate the CT findings that can help arrive at the diagnosis.

Clinical presentation may be highly variable, ranging from asymptomatic to chronic pain in the right upper quadrant, cholecystitis, and even pancreatitis. It may be associated with other bile duct abnormalities such as choledochal cyst, ectopic gallbladder or anomalous biliopancreatic junction.

    Introduction Morphology of gallbladder varies considerably from person to person. We believe that one of the morphological variations of gallbladder is the “gallbladder angle”. Gallbladder varies also in “angle”, which, to the best of our knowledge, has never been investigated before. The purpose of this study was to investigate the impact of gallbladder angle on gallstone formation. Methods in this study, 1075 abdominal computed tomography (CT) images were retrospectively examined. Patients with completely normal gallbladders were selected. Among these patients, those with both abdominal ultrasound and blood tests were identified in the hospital records and included in the study. Based on the findings of the ultrasound scans, patients were divided into two groups as patients with gallstones and patients without gallstones. Following the measurement of gallbladder angles on the CT images, the groups were statistically evaluated. Results The gallbladder angle was smaller in patients with gallstones (49 ± 21 degrees and 53 ± 19 degrees) and the gallbladder with larger angle was 1.015 (1/0.985) times lower the risk of gallstone formation. However, these were not statistically significant (p>0,05). Conclusion A more vertically positioned gallbladder does not affect gallstone formation. However, a smaller gallbladder angle may facilitate gallstone formation in patients with the risk factors. Gallstones perhaps more easily and earlier develop in gallbladders with a smaller angle.

    Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are causes of bowel perforation in premature neonates. Studies have demonstrated that both are associated with acute chorioamnionitis (ACA) of the placenta. The aim of our study was to identify any histopathological links between placental histopathological abnormalities and the later development of NEC and/or SIP in premature patients presenting at our institution. Cases with a diagnosis of NEC/SIP were identified. Entry criteria were the diagnosis of NEC/SIP was confirmed clinically and/or histologically, had been made within the first 7 days of life, neonates were premature, and the placenta had been submitted for histological examination. In those cases with ACA, CD34 immunohistochemistry and Martius scarlet blue staining was performed. Medical records were reviewed for demographics, clinical variables, and clinical outcomes. Statistical analysis was performed using Fisher exact test. In total, 21 cases met defined inclusion criteria (12 NEC, 8 SIP, and 1 clinically indeterminate). Mean gestational age was 27 weeks. Median age of presentation was 5 days. Placental histology showed ACA in 16 of 21 cases (76.2%). Of those with ACA, 13 of 16 (81.3%) had umbilical phlebitis, 12 of 16 (75.0%) had umbilical arteritis, 6 of 16 (37.5%) funisitis, and 12 of 16 (75.0%) had chorionic vasculitis. No differences (p > 0.05) were seen between ACA and diagnosis or clinical outcome (Fisher exact test). Of the 16 cases, 14 with ACA that later developed either NEC or SIP showed vasculitis in the umbilical cord and/or chorionic plate and/or stem villi vasculature. The association between ACA and vasculitis was highly significant (p < 0.01). Of those with ACA on placental histology, 12 of 16 (75.0%) cases were found to have intermediate-advanced stage fetal inflammatory response (FIR), whereas 13 of 16 (81.3%) had grade 2 (severe) FIR. Of the 16 cases, 8 (50.0%) had evidence of fibrin deposition

    Gallbladder cancer, though generally considered rare, is the most common malignancy of the biliary tract, accounting for 80%–95% of biliary tract cancers. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis, often proving fatal. Its carcinogenesis follows a progression through a metaplasia–dysplasia–carcinoma sequence. This comprehensive review focuses on and explores the risks, management, and outcomes for primary gallbladder carcinoma. Epidemiological studies have identified striking geographic and ethnic disparities – inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Age, female sex, congenital biliary tract anomalies, and a genetic predisposition represent important risk factors that are immutable. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Mortality rates closely follow incidence; those countries with the highest prevalence of gallstones experience the greatest mortality from gallbladder cancer. Vague symptoms often delay the diagnosis of gallbladder cancer, contributing to its overall progression and poor outcome. Surgery represents the only potential for cure. Some individuals are fortunate to be incidentally found to have gallbladder cancer at the time of cholecystectomy being performed for cholelithiasis. Such an early diagnosis is imperative as a late presentation connotes advanced staging, nodal involvement, and possible recurrence following attempted resection. Overall mean survival is a mere 6 months, while 5-year survival rate is only 5%. The dismal prognosis, in part, relates to the gallbladder lacking a serosal layer adjacent to the liver, enabling hepatic invasion and metastatic progression.

    A 4-year-old neutered male Chihuahua was presented with a history of anorexia and vomiting. Continuous elevation of liver enzymes was found on repeated blood examinations and the dog was referred to us for further evaluation. The absence of gallbladder was suspected on ultrasonography. Exploratory laparotomy and retrograde cholangiography confirmed gallbladder agenesis and a possible hypoplasia of the right medial and lateral liver lobes. Histologically, proliferation of bile ductules associated with portal fibrosis and pseudolobular formation were apparent in the liver lobes.

    Nine patients with calcification of the gallbladder wall (porcelain gallbladder) were analyzed by ultrasound and the appearance correlated with the CT, radiographic, clinical, and surgical findings. Three distinct patterns were identified: (a) a hyperechoic similunar structure with acoustic shadowing posteriorly, simulating a stone-filled gallbladder devoid of bile, which was seen in 5 patients; (b) a biconvex, curvilinear echogenic structure with variable acoustic shadowing, seen in all 3 patients with carcinoma of the gallbladder; and (c) an irregular clump of echoes with posterior acoustic shadowing, seen in 1 patient. Potential pitfalls in the diagnosis of gallbladder calcification are presented, and the association between calcification and cancer is emphasized.

    Gall-bladder duplication is a rare anatomical variation, which can affect safe performance of cholecystectomy and be a cause of persistent symptoms and a need for reoperation in case of accessory gall-bladder omission. A case of successfully performed elective laparoscopic cholecystectomy in a patient with duplicated gall-bladder accidentally intraoperatively disclosed is presented. The identified anomaly was classified according to the Harlaftis Classification of Multiple Gall-bladders. Attention was drawn to the uneffectivenes of ultrasound scanning in multiple gall-bladders preoperative detecting, and presence of other non-biliary anatomical variation in the same individual as well.

    Scrub typhus is an acute febrile illness usually presenting with fever, myalgia, headache, and a pathognomonic eschar. Severe infection may lead to multiple organ failure and death. Gastrointestinal tract involvement in the form of gastric mucosal erosions and ulcerations owing to vasculitis resulting in gastrointestinal bleeding is common. This process may worsen a pre-existent asymptomatic peptic ulcer, causing duodenal perforation, and present as an acute abdomen requiring surgical exploration. We report the case of a patient with no previous symptoms or risk factors for a duodenal ulcer, who presented with an acute duodenal perforation, probably precipitated by scrub typhus infection.

    Background For children at high risk of chronic suppurative otitis media (CSOM), strategies to prevent acute otitis media with perforation (AOMwiP) may reduce progression to CSOM. Methods In a double blind study in northern Australia, 103 Aboriginal infants with first detection of OME were randomised to receive either amoxicillin (50 mg/kg/d BD) or placebo for 24 weeks, or until bilateral aerated middle ears were diagnosed at two successive monthly examinations (success). Standardised clinical assessments and international standards for microbiology were used. Results Five of 52 infants in the amoxicillin group and none of 51 infants in the placebo group achieved success at the end of therapy (Risk Difference = 9.6% [95% confidence interval 1.6,17.6]). Amoxicillin significantly reduced the proportion of children with i) perforation at the end of therapy (27% to 12% RD = -16% [-31,-1]), ii) recurrent perforation during therapy (18% to 4% RD = -14% [-25,-2]), and iii) reduced the proportion of examinations with a diagnosis of perforation during therapy (20% to 8% adjusted risk ratio 0.36 [0.15,0.83] p = 0.017). During therapy, the proportion of examinations with penicillin non-susceptible (MIC > 0.1 microg/ml) pneumococci was not significantly different between the amoxicillin group (34%) and the placebo group (40%). Beta-lactamase positive non-capsular H. influenzae (NCHi) were uncommon during therapy but more frequent in the amoxicillin group (10%) than placebo (5%). Conclusion Aboriginal infants receiving continuous amoxicillin had more normal ears, fewer perforations, and less pneumococcal carriage. There was no statistically significant increase in resistant pneumococci or NCHi in amoxicillin children compared to placebo children who received regular paediatric care and antibiotic treatment for symptomatic illnesses.

Although involvement of any part of the gastrointestinal tract may occur with disseminated histoplasmosis, the complication of intestinal perforation requiring emergency surgery (particularly in the colon) is extremely rare and warrants this case report with discussion of the various clinicopathologic features of gastrointestinal histoplasmosis and the occurrence of primary intestinal histoplasmosis.

    2016-11-01

    Gallbladder calcification, also referred to as porcelain gallbladder, has received significant attention in the medical literature due to its perceived role in increasing the risk of developing a gallbladder carcinoma. However, recent reports raise questions challenging this purported high risk. While previous studies reported a concomitant incidence of gallbladder cancer in porcelain gallbladder ranging from 7-60%, more recent analyses indicate the incidence to be much lower (6%). Based on evidence in the current literature, a prophylactic cholecystectomy is not routinely recommended for all patients with porcelain gallbladder and should be restricted to those with conventional indications, such as young patients. However, it is important to note that a nonoperative approach may require prolonged follow-up. A laparoscopic cholecystectomy is a feasible therapeutic option for patients with porcelain gallbladder, although some researchers have indicated a higher incidence of complications and conversion due to technical difficulties.

    Background The requirement for subsequent cholecystectomy in patients with gallbladder in situ after endoscopic removal of stones from the common bile duct (CBD) is controversial. The aims of this study were to assess the requirement for subsequent cholecystectomy for gallbladder-related symptoms, and to identify the patients who develop symptoms after the endoscopic removal of CBD stones. Methods Of 241 patients with gallbladder in situ following endoscopic removal of stones from the CBD, 146 patients (78 men and 68 women; mean age 69±13 years, range 20–93) with a follow-up time of more than three months without elective cholecystectomy were enrolled in the study. Fifty-nine patients had gallbladder stones (single stones in 27 and multiple stones in 32) and 87 patients had gallbladder in situ without stones. The time from entry to the occurrences of death or cholecystectomy was evaluated retrospectively. Cox regression analysis was used to evaluate the risk factors associated with these events. Results The mean duration of follow-up was 24.1±18.0 months (range 3–70 months). During follow-up, seven patients (4.8%) underwent cholecystectomy, on average 18.4 months after CBD stone removal, as the result of acute cholecystitis in four cases, biliary pain in two cases and acute pancreatitis in one case. Laparoscopic cholecystectomy was performed in four patients and open cholecystectomy in three patients. Post-operative morbidity occurred in two patients, with improvement after conservative management. Nine patients (6.2%) died as the result of unrelated biliary disease. Age, sex, presence of gallbladder stones, multiplicity of gallbladder stones and underlying disease did not correlate with subsequent cholecystectomy by Cox regression analysis. Conclusion Elective cholecystectomy is not warranted in patients with bile duct stones when the common duct can be cleared of stones by endoscopic sphincterotomy. We could not find any clinical predictors of further

    Cholelithiasis is a very common disease in the United States. Most cases remain asymptomatic but a fraction of these patients can develop serious complications such as cholecystitis which may lead to gallbladder perforation and gallbladder cancer which is much less common. Here, we present three cases of cholelithiasis where transthoracic echocardiography was performed routinely. In each case, echocardiography detected cholelithiasis which prompted three-dimensional (3D) echocardiographic evaluation. Three-dimensional echocardiography allowed for more comprehensive examination of the gallbladder shape, size, and wall thickening and the measurement and composition of the stones in three dimensions, measurement of stone volumes, and minimized shadowing produced by stone calcifications. These cases suggest that routine echocardiography has value in detecting gallstones and that 3D echocardiography has incremental value over two-dimensional echocardiography due to pyramidal data sets which allow sequential slicing through the gallbladder and full gallbladder examination without a technologist who is trained in gallbladder imaging. These pyramidal data sets can be further viewed and cropped by a radiologist specialized in abdominal ultrasound. © 2012, Wiley Periodicals, Inc.

    Improvements in radiologic localization have made percutaneous catheter drainage (PCD) the initial procedure of choice for many intra-abdominal abscesses (IAA). During the past seven years 154 patients underwent PCD for treatment of abdominal abscesses. Fourteen of these patients had PCD as the initial treatment for IAA secondary to a perforated viscus and subsequently underwent an elective one-stage operation to treat the underlying disease. Etiologies of the abscesses included perforated appendicitis in six patients, sigmoid diverticulitis in three patients, Crohn's ileitis in two patients, and one case each of perforated gastric ulcer, perforated sigmoid carcinoma, and perforated gallbladder. Initial localization of the abscess was achieved by either CT or ultrasound. Seven abscesses were localized in the right lower quadrant, four were localized in the liver, and one was localized each in the left flank, right flank, subhepatic space, and pelvis. All patients subsequently underwent a definitive elective operation for their primary disease including six interval appendectomies, four sigmoid colectomies, two small-bowel resections, one subtotal gastrectomy and one cholecystectomy. There were no complications due to PCD and no deaths occurred. We conclude that PCD can be successfully performed as the initial treatment for IAA associated with a perforated viscus, obviating the first stage of the traditional two-stage surgical approach.

    Partial cholecystectomy is usually performed with the aim of preventing bile duct injury and/or vascular injuries in situations where there is difficulty in performing cholecystectomy. Occasionally, such patients can become symptomatic due to recurrence or persistence of disease in the gallbladder remnant and may require further treatment. A case series of various presentations and follow up of seven patients who had undergone open partial cholecystectomy for symptomatic gallstone disease in the past. Of 7 patients, 6 were symptomatic, and each of them was found to have a remnant of the gallbladder (with calculi in the remnant in 4 patients). Three patients who presented with recurrent biliary symptoms were re-operated and the gallbladder remnant was removed, with resolution of the symptoms. Two patients refused further operation-one patient with acute pancreatitis who underwent endoscopic retrograde cholangiopancreatography (ERCP) for removal of common bile duct stones, and another who presented with acute cholecystitis. The other 2 patients (one with transient jaundice and the other who is asymptomatic) remain on follow-up. Although partial cholecystectomy is an accepted, safe option in difficult cases, these patients must be counselled regarding the recurrence of symptoms, and must be kept on follow-up. If symptoms develop, completion of cholecystectomy to remove the remnant provides symptomatic relief.

    Objective To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases), increased density of mesenteric fat (in all four cases), identification of the foreign body passing through the intestinal wall (in three cases), and gas in the peritoneal cavity (in one case). Conclusion In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

The majority of the available data have been reported in the neonatal age group. There are a few cases of spontaneous gastric perforation in preschool children. To our knowledge, there is no published information on spontaneous gastric perforation in older children and adolescents. Case Report: We describe the presentation and clinical course of two adolescent children who presented with spontaneous gastric perforation. Both children presented with acute onset abdominal pain, which progressively worsened. In both cases, the patient were taken urgently to the operating room after imaging studies had shown pneumoperitoneum. In both cases, surgery revealed gastric perforation with no obvious etiology, specifically no ulcer, inflammation, or other pathology. Conclusions: These two cases highlight the importance of including spontaneous gastric perforation, not just the typical duodenal/gastric ulcer, in the differential of a patient with severe abdominal pain and distension, who has imaging showing pneumoperitoneum.

The patient was admitted for abdominal pain, abdominal swelling, and consciousness disorder 18 days after the onset. Abdominal computed tomography (CT) revealed emphysema in the gallbladder and a small amount of intraperitoneal free gas. Intraoperative findings suggested gangrenous cholecystitis. The gallbladder wall was perforated, and an abscess involving the right subphrenic region, the periphery of the liver and gallbladder, and the right paracolonic groove, was detected. The flare on the body surface may have reflected abscess formation in the right abdominal cavity. Emphysematous cholecystitis induces necrosis and perforation in many patients, and immediate strategies such as emergency surgery are important.

    Histological lesions of gallbladder were described mainly in older patients with cholelithiasis (CH). The aim of the study was to analyse morphological alterations in gallbladder mucosa and selected clinical data of young patients with CH. The studies were conducted on 57 patients with CH, subjected to cholecystectomy in the years of 2003-2007. In course of the years, 37 respective young patients (below 25 years of age) were operated. The comparative group included twenty 50-year-old patients with gallstones. The inflammatory activity (grading) was evaluated using a semiquantitative scale on HE-stained gallbladders. In either group, women with chronic cholecystitis and multiple gallstones prevailed. Histological alterations in young patients involved absence of evident epithelial metaplasia traits, low number of foamy cells and prevalence of eosinophils in gallbladder mucosa. Even if a similar grading in gallbladder walls was noted in young and older patients, only in the former ones, a higher grading was detected in patients with an acute clinical course of the gallstone disease. The results point also to a potential role of local accumulation of eosinophils in gallbladder mucosa in pathogenesis of CH in young patients.

    Chronic inflammation is a risk factor for gallbladder carcinoma. The molecular mechanisms linking inflammation and gallbladder carcinogenesis are incompletely understood. Toll-like receptors are involved in inflammatory response and play an important role in the innate immune system by initiating and directing immune response to pathogens. We tested the hypothesis that TLR4 participated in the development of gallbladder carcinoma through investigating the expression of TLR4 in chronic cholecystitis, gallbladder carcinoma and normal gallbladder. The expression of TLR4 in 30 specimens of chronic calculous cholecystitis, 13 specimens of gallbladder adenocarcinoma and 10 specimens of normal gallbladder tissue was determined by immunohistochemistry, western blotting analysis and quantitative RT-PCR. We showed that TLR4 was mostly localized to the glandular and luminal epithelium of gallbladder. TLR4 expression was lower in gallbladder carcinoma tissue than in chronic cholecystitis and normal gallbladder tissue, whereas the difference between chronic cholecystitis tissue and normal gallbladder tissue was not statistically significant. The expression of TLR4 may be closely associated with the course of gallbladder carcinoma.

    Two hundred and sixty two patients with gallbladder stones were prospectively evaluated at the Biliary Lithiasis Treatment Unit of the Mater Dei Hospital, Belo Horizonte, MG., and 45 (17.5%) were selected for extracorporal shock wave lithotripsy (ECSWL). From these, 32 were submitted to the procedure. One stone was present in 30 patients, 2 stones in another and 1 patient had 3 stones. The mean diameter was 14.7 mm ranging from 8 to 28 mm. ECSWL was preceded by 1 week course of ursodeoxycholic acid (8 to 10 mg/dk/day) and this medication was continued after the procedure. ECSWL was done with the Lithosthar-Plus apparatus (Siemens). Meperidine (up to 100 mg) IM and pirazolene IV was given when necessary. The intensity of the shock waves was gradually increased to a maximum (9 bar) whenever tolerated. The treatment was well succeeded in 22 cases (71%) with pulverization in 12 (38.7%). In 9 patients (29%) remaining fragments were greater than 4 mm. From these, 3 were submitted to a second session of ECSWL. In 1 patient the stone could not be properly positioned for lithotripsy. The mean number of shock waves was 2,591, ranging from 801 to 4,411. The mean duration of the sessions was 80 min, ranging from 45 to 150 min. In 3 patients, a complete disappearance of fragments was observed in intervals of 1 to 6 months after the procedure. One patient had severe pain during ECSWL and developed acute cholecystitis. One patient had sinus bradycardia. One patient with total stone pulverization, become jaundiced 1 month after ECSWL and a gallbladder carcinoma was found at surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

    Fine needle aspiration (FNA) is not a commonly performed procedure for gallbladder lesions for fear of causing biliary peritonitis; hence data on gallbladder cytology is scarce. The aims of the present study were to evaluate the diagnostic application of ultrasound-guided (US) FNA cytology in the pre-operative diagnosis of neoplastic as well as non-neoplastic lesions of the gallbladder and to review the cytomorphological spectrum of gallbladder lesions encountered along with various diagnostic difficulties that can arise during reporting. The study was carried out on 596 patients with gallbladder lesions in whom US-guided FNA was performed over a 5-year period. In 130 cases, simultaneous aspirations from other organs were done. The histological correlation was available in 32 cases. No major complications such as haemorrhage, peritonitis, etc. were encountered related to the procedure. The majority were mass lesions whereas in 73 cases (12.2%) only focal or diffuse gallbladder wall thickening was present. Cytological examination of 596 cases revealed malignancy in 462 (77.6%), 26 (4.4%) suspicious of malignancy, 23 (3.8%) inflammatory lesion, 29 negative (4.8%) and 56 cases showed necrosis only or were inadequate for any definite opinion. The lesions diagnosed on FNA cytology included carcinoma (predominantly adenocarcinoma), xanthogranulomatous cholecystitis (XGC), acute suppurative inflammation and tuberculosis. Of 26 with adequate cytology, 24 were accurate with respect to malignant (including one suspicious FNA) versus benign: one false positive and one false negative both involved xanthogranulomatous change. The present study is the largest series evaluating the role of US-guided FNA in the diagnosis of gallbladder lesions. It is a safe, rapid, reliable, cost-effective and reasonably accurate method for diagnosing gallbladder lesions. FNA should always be attempted in cases with a mass lesion. © 2016 John Wiley & Sons Ltd.

    Secretion of mucoproteins or mucine (MP) have been studied as possible markers in several pathological conditions of the digestive tract, such us colonic polyposis or gastric dysplasia. In the gallbladder (VB) it has been established that form the core of crystalization for the calculi. A study in 100 gallbladders have been made based on the utility of the analysis of the qualitative and quantitative modifications of MP in lithogenesis. It was been determined by histochemical techniques the three main types of MP (neutral, low and high sulphated acid) to evaluate the alterations in the process of lithiasis. Results show a high production of the MP in VB with lithiasis, presenting in 97% a mixed composition of MP (48.9% of 2 types, and 3 types in 46%), without a predominating type in this pathology.

    This article reviews the most relevant ultrasound findings associated with gallbladder cancer. A descriptive and retrospective study was made of clinical features and imaging studies in patients subjected to surgery for gallbladder neoplasm in the Reina Sofía General University Hospital (Murcia) during the time period 2000-2011. A total of 15 cases of gallbladder cancer were found during the study period, 9 of whom were women. The mean age was 77 years (range 61-96). Pain was the principal complaint. The patients had cholelithiasis in 13 cases, smoking in 2 cases, and obesity in 3 cases. The ultrasound showed gallbladder wall thickening (>4mm) in 8 cases, intraluminal mass in 4, scleroatrophic gallbladder in 2, and mass replacing the gallbladder in one. Only in 4 cases was the suspicion of gallbladder carcinoma established preoperatively. According to the pTNM staging, 4 patients were carcinoma in situ (Tis), one case T1a, 6 cases T2, 3 cases T3 and one case T4. In 7 cases, the only evidence was the preoperative ultrasound, and in 8 the study was completed with an abdominal CT. Early diagnosis of gallbladder cancer is rare. The ultrasound diagnostic approach is difficult; only a localized thickening coexisting with gallstones seems to be significant, and requires a biopsy. The image of a mass and a stone occupying the gallbladder is associated with later stages of the disease. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    The objective of this study is to report the diagnostic features of hematogenous gallbladder metastasis using various imaging modalities. We carried out a single-center retrospective analysis of 13 patients with gallbladder metastasis. The primary malignancy was cutaneous melanoma (11 cases), hepatocellular carcinoma (1 case), and non-Hodgkin lymphoma (1 case). All patients underwent sonography (US), with color-power-Doppler assessment in 11 cases. Contrast-enhanced US (CEUS) was performed in 8 patients, MDCT in 8, and MR imaging in 1. Four subjects studied by whole-body PET. The gallbladder lesions were first detected with US in 9 cases and with MDCT in 3 cases. The remaining patient was investigated because of hepatic fluorodeoxyglucose uptake at PET; CEUS failed to detect any liver metastasis in this subject but identified a gallbladder lesion. Typical findings included multiplicity of gallbladder vegetations, broad base, limited mural thickening, presence of contrast enhancement, absence of gallstones and gallbladder bed infiltration, presence of combined lesions within other organs. Only two patients presented an isolated location in the gallbladder and were successfully treated with surgery. Gallbladder metastasis is a rare but possible occurrence. Knowledge of the typical imaging features and careful evaluation of the gallbladder may avoid an incorrect or false negative diagnosis.

    Gallbladder cancer is a rather uncommon disease, when it gives symptoms it has usually reached an incurable stage. Therefore, every attempt must be made to find the asymptomatic stages and look for premalignant gallbladder polyps. Even if gallbladder cancer is a rare disease, gallbladder polyps are common, only a few polyps develop to cancer. This makes gallbladder polyps another problem: which are the polyps that must be surgically removed, which shall be followed-up, or for how long? The author used the keyword “gallbladder polypsn” in PubMed and reviewed the scientific literatures published from January 2000 to December 2011. The present review article has summarized almost all respects of gallbladder polyp, including the risk factors, clinical diagnosis and management, and comments made from the author, in which clinical treatments are recommended. It is author's purpose that the 11-year-knowledge about gallbladder polyps summarized from all worlds’ literatures is enough to know how clinicians will handle the next patient with gallbladder polyp.

    Ceftriaxone has been associated with development of pseudolithiasis. In our institution, it is used for treatment of perforated appendicitis in children. This study evaluated the occurrence of ceftriaxone-related pseudolithiasis in this population. After obtaining IRB approval, we performed a retrospective chart review over 51 months. We included patients undergoing laparoscopic appendectomy for perforated appendicitis. All patients were treated with ceftriaxone post-operatively. Patients without initial or post-treatment gallbladder imaging available for review were excluded. There were 71 patients who met inclusion criteria with a mean (±SD) age of 10.8 ± 3.8 years. Of these, 14 % (n = 10) developed stones or sludge in the gallbladder. The mean duration of ceftriaxone therapy was 8.7 ± 3.8 days. The average time to post-antibiotic imaging was 11.5 ± 10.3 days from initiation of antibiotics. There was no significant difference in duration of ceftriaxone therapy in the children that developed pseudolithiasis or sludge (10.0 ± 4.9 days) compared to those that did not (8.5 ± 3.6, p = 0.26). One child (10 %) with pseudolithiasis went on to become symptomatic, requiring a laparoscopic cholecystectomy. In our experience, ceftriaxone use for perforated appendicitis is associated with a significant incidence of biliary pseudolithiasis, and is unrelated to duration of ceftriaxone therapy.

    Aflatoxin, which causes hepatocellular carcinoma, may also cause gallbladder cancer. We investigated whether patients with gallbladder cancer have higher exposure to aflatoxin than patients with gallstones. We measured aflatoxin B1 (AFB1)-lysine adducts in plasma samples from the Shanghai Biliary Tract Cancer case-control study, conducted from 1997 through 2001. We calculated age- and sex-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) and the population-attributable fraction for 209 patients with gallbladder cancer and gallstones vs 250 patients with gallstones without cancer (controls). In 54 patients with gallbladder cancer, tumor tissue was examined for the R249S mutation in TP53, associated with aflatoxin exposure, through targeted sequencing. The AFB1-lysine adduct was detected in 67 (32%) of 209 patients with gallbladder cancer and 37 (15%) of the 250 controls (χ(2) P < .0001), almost threefold more patients with gallbladder cancer than controls (OR, 2.71; 95% CI, 1.70-4.33). Among participants with detectable levels of AFB1-lysine, the median level of AFB1-lysine was 5.4 pg/mg in those with gallbladder cancer, compared with 1.2 pg/mg in controls. For patients in the fourth quartile of AFB1-lysine level vs the first quartile, the OR for gallbladder cancer was 7.61 (95% CI, 2.01-28.84). None of the 54 gallbladder tumors sequenced were found to have the R249S mutation in TP53. The population-attributable fraction for cancer related to aflatoxin was 20% (95% CI, 15%-25%). In a case-control study of patients with gallbladder cancer and gallstones vs patients with gallstones without cancer, we associated exposure to aflatoxin (based on plasma level of AFB1-lysine) with gallbladder cancer. Gallbladder cancer does not appear associate with the R249S mutation in TP53. If aflatoxin is a cause of gallbladder cancer, it may have accounted for up to 20% of the gallbladder cancers in Shanghai, China, during the study period, and could account for an

    Introduction By presenting this case we aimed to describe an uncommon complication of generalized peritonitis following spontaneous pyometra perforation in untreated cervical carcinoma. Case Presentation This report describes a 60-year-old postmenopausal woman presenting with clinical features mimicking intestinal perforation who was later diagnosed as cervical carcinoma with pyometra perforation at exploratory laparotomy. The patient had good post-operative recovery following drainage and peritoneal lavage. Conclusion Spontaneous pyometra perforation in a case of untreated carcinoma of cervix is a rare condition, yet it should be suspected and kept in the differential diagnosis of acute abdomen in elderly women.

    Background There is still confusion and controversy over the diagnosis and optimal surgical treatment of non traumatic terminal ileal perforation-a cause of obscure peritonitis. Methods This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation. Results There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%), nonspecific inflammation(26%), obstruction(6%), tuberculosis(4%) and radiation enteritis (1%). Simple closure of the perforation (49%) and end to side ileotransverse anastomosis(42%) were the mainstay of the surgical management. Conclusion Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

    AIM: To review and evaluate the diagnostic dilemma of xanthogranulomatous cholecystitis (XGC) clinically. METHODS: From July 2008 to June 2014, a total of 142 cases of pathologically diagnosed XGC were reviewed at our hospital, among which 42 were misdiagnosed as gallbladder carcinoma (GBC) based on preoperative radiographs and/or intra-operative findings. The clinical characteristics, preoperative imaging, intra-operative findings, frozen section (FS) analysis and surgical procedure data of these patients were collected and analyzed. RESULTS: The most common clinical syndrome in these 42 patients was chronic cholecystitis, followed by acute cholecystitis. Seven (17%) cases presented with mild jaundice without choledocholithiasis. Thirty-five (83%) cases presented with heterogeneous enhancement within thickened gallbladder walls on imaging, and 29 (69%) cases presented with abnormal enhancement in hepatic parenchyma neighboring the gallbladder, which indicated hepatic infiltration. Intra-operatively, adhesions to adjacent organs were observed in 40 (95.2%) cases, including the duodenum, colon and stomach. Thirty cases underwent FS analysis and the remainder did not. The accuracy rate of FS was 93%, and that of surgeon’s macroscopic diagnosis was 50%. Six cases were misidentified as GBC by surgeon’s macroscopic examination and underwent aggressive surgical treatment. No statistical difference was encountered in the incidence of postoperative complications between total cholecystectomy and subtotal cholecystectomy groups (21% vs 20%, P > 0.05). CONCLUSION: Neither clinical manifestations and laboratory tests nor radiological methods provide a practical and effective standard in the differential diagnosis between XGC and GBC. PMID:26640342

    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.

  4. Spontaneous free perforation of the small intestine in adults

    Spontaneous free perforation of the small intestine is uncommon, especially if there is no prior history of visceral trauma. However, free, even recurrent, perforation may complicate a defined and established clinical disorder, such as Crohn’s disease. In addition, free perforation may be the initial clinical presentation of an occult intestinal disorder, such as a lymphoma complicating celiac disease, causing diffuse peritonitis and an acute abdomen. Initial diagnosis of the precise cause may be difficult, but now has been aided by computerized tomographic imaging. The site of perforation may be helpful in defining a cause (e.g., ileal perforation in Crohn’s disease, jejunal perforation in celiac disease, complicated by lymphoma or collagenous sprue). Urgent surgical intervention, however, is usually required for precise diagnosis and treatment. During evaluation, an expanding list of other possible causes should be considered, even after surgery, as subsequent management may be affected. Free perforation may not only complicate an established intestinal disorder, but also a new acute process (e.g., caused by different infectious agents) or a longstanding and unrecognized disorder (e.g., congenital, metabolic and vascular causes). Moreover, new endoscopic therapeutic and medical therapies, including use of emerging novel biological agents, have been complicated by intestinal perforation. Recent studies also support the hypothesis that perforation of the small intestine may be genetically-based with different mutations causing altered connective tissue structure, synthesis and repair.

    One hundred and two patients with perforated duodenal ulcers over a 13 year period (1970 to 1982) have been prospectively followed-up at a special gastric clinic. Of the 37 patients with perforation of their acute ulcer, 34 were treated by oversew and three had an initial definitive operation (vagotomy and drainage). The remaining 65 patients presented with perforation of a chronic ulcer and 54 were treated by oversew and 11 underwent definitive surgery--nine had vagotomy and drainage and two had partial gastrectomies. Seven of the 34 patients (20.5%) with acute ulcer perforation treated by simple oversew subsequently required definitive ulcer surgery at a mean 17.5 months after perforation and 31 of the 54 patients (57.4%) with chronic ulcer perforations required definitive surgery at a mean 27.4 months after perforation. The introduction of H2 antagonists in 1977 did not alter the re-operation rate in patients with chronic ulcer perforation managed by oversew. Results of this study provide further evidence in favour of treating patients with perforation of their chronic duodenal ulcer by definitive surgery whenever possible. PMID:3789618

    The effects of peptide YY (PYY) on cholecystokinin-stimulated gallbladder contraction were investigated in the prairie dog model. Twelve animals underwent laparotomy with catheter placement into the gallbladder and common bile duct (vent). The gallbladder was continuously perfused with (/sup 14/C)polyethylene glycol-labeled lactated Ringer at 0.03 ml/min, and vent effluent was collected at 2.5-min intervals. All animals received 20 min of intravenous infusion of cholecystokinin octapeptide (CCK-OP), 2.5 ng x kg/sup -1/ x min/sup -1/, immediately followed by 60-min infusions of either lactated Ringer (LR) or synthetic PYY, 10 or 50 ng x kg/sup -1/ x min/sup -1/. When LR was infused after CCK-OP, gallbladder filling increased by 15.4 +/- 10.5% with minimal changes in gallbladder pressure. Infusion of PYY/sub 10/ resulted in a significant increase in gallbladder volume and filling with a significant decrease in intragallbladder pressure. Similar findings were noted with PYY/sub 50/. These data indicate that synthetic PYY significantly augments gallbladder filling after CCK-OP-stimulated gallbladder contraction. These finding, coupled with the observation that PYY inhibits pancreatic secretion, suggest that this peptide may be the anti-CCK hormone and may have an important role in regulating biliary activity postprandially.

  7. Agenesis of the Gallbladder: Lessons to Learn

    PubMed Central

    Singhal, Tarun; Grandy-Smith, Starlene; El-Hasani, Shamsi

    2006-01-01

    Background: Congenital absence of the gallbladder is a rare, usually asymptomatic, anatomical variation. Some affected individuals may present with a clinical picture suggestive of gallbladder disease. This presentation, coupled with the inability of standard abdominal ultrasonography to convincingly diagnose agenesis of the gallbladder, can put the surgeon in a diagnostic and intraoperative dilemma. Case Report: A 30-year-old lady presenting with clinical features of cholecystitis and diagnosed with shrunken gallbladder on ultrasonography was scheduled for laparoscopic cholecystectomy. Intraoperatively, the gallbladder could not be seen even after thorough dissection in the region of the porta hepatis. The procedure was terminated at this stage, and further imaging of the extrahepatic biliary system by magnetic resonance cholangiopancreatography and endoscopic ultrasound confirmed the diagnosis of congenital absence of the gallbladder. Conclusion: Nonvisualization of the gallbladder at laparoscopy, in the absence of any other diagnosed biliary disorder, need not prompt conversion to open exploration of the extrahepatic biliary system. Newer imaging modalities are relatively noninvasive and can provide good delineation of biliary anatomy. This allows well-planned treatment and at the same time prevents the added morbidity of a diagnostic laparotomy performed solely to confirm the absence of the gallbladder. PMID:17575771

    Impairment in gallbladder emptying, increase in residual volume, and reduced smooth muscle contractility are hallmarks of acute acalculous cholecystitis and seem to be related to ischemia/reperfusion (I/R). This study was designed to determine the effects of tempol, a general antioxidant, on I/R-induced changes in gallbladder contractile capacity, the mechanisms involved in the contractile process, and the level of inflammatory mediators. Experimental gallbladder I/R was induced in male guinea pigs by common bile duct ligation for 2 days, then a deligation of the duct was performed and after 2 days the animals were sacrificed. A group of animals was treated with tempol, administered in the drinking water at 1 mmol/l for 10 days prior the bile duct ligation and until animal sacrifice. Isometric tension recordings showed that KCl and cholecystokinin-induced contractions were impaired by I/R, which correlated with decreased F-actin content and detrimental effects on Ca(2+) influx. In addition, I/R depolarized mitochondrial membrane potential, as indicated by the reduction of the heterogeneity of the rhodamine123 fluorescence signal, and increased the expression of NF-kappaB, COX-2, and iNOS. Tempol treatment improved contractility via normalization of Ca(2+) handling and improvement of F-actin content. Moreover, the antioxidant ameliorated mitochondrial polarity and normalized the expression levels of the inflammatory mediators. These results show that antioxidant treatment protects the gallbladder from I/R, indicating the potential therapeutic benefits of tempol in I/R injury.

    Patients receiving total intravenous nutrition have inert gallbladders; gallbladder sludge and gallstones often develop, but are preventable if gallbladder emptying can be improved. We measured the effect of giving rapid intravenous infusions of aminoacid solutions in eight normal subjects. Four regimens were tested (250 mL over 30 min, 250 mL over 10 min, 125 mL over 5 min, and 50 mL over 5 min). Gallbladder emptying, as measured by ultrasound and cholecystokinin release, depended on both the amount and the rate of aminoacid infusion. Rapid infusion of 125 mL of an aminoacid mixture (Synthamin 14 without electrolytes) over 5 min (2.1 g per min) produced a 64% reduction in gallbladder volume within 30 min, whereas a 50 mL infusion over 5 min produced only a 22% reduction. Intermittent rapid infusion of small amounts of aminoacids may prevent gallstones in patients receiving intravenous nutrition.

    Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer. PMID:28138363

    Perforation of Meckel's diverticulum with enteroliths is a rare complication. Here, we report a case of perforation of Meckel's diverticulum with enteroliths, which could be accurately diagnosed by the preoperative computed tomography (CT). A 46-year-old man with acute onset of severe abdominal pain, and a localized muscle guarding in the right hypochondrium, had a solitary stone detected in the right abdomen by the radiography. The abdominal CT revealed a saclike outpouching of the small intestine, containing air/fluid levels and an enterolith, with surrounding free air and mesenteric inflammatory change in the right paraumbilical area. He was diagnosed as the perforation of Meckel's diverticulum with enterolith, and the emergency operation was indicated. The perforated Meckel's diverticulum was identified approximately 90 cm proximal to the ileocecal valve. The diverticulum was transected at the base, and removed. The patient's postoperative course was uneventful. This case strongly suggested the ability of CT enterography to accurately diagnose pathologies involving the small intestine, such as the perforation of Meckel's diverticulum, which open premises for its use in the diagnosis of acute abdomen preoperatively.

    For patients with small bowel and colonic perforations, a definitive diagnosis of the cause of perforation is not necessary before operation. Bowel obstruction and inflammatory bowel disease are the most common causes of nontraumatic intestinal perforations in industrialized countries, whereas infectious causes of intestinal perforations are more common in developing countries. Treatment of small bowel and colonic perforations generally includes intravenous antibiotics and fluid resuscitation, but the specific management of the bowel depends on the underlying cause of the perforation.

    The surgery of gallbladder polyps is not well defined due to the lack of evidence-based clinical guidelines. To analyse the management of polyps in Spain, and a review of the literature and treatment standards. The reports on cholecystectomy with gallbladder polyps (GBP) were extracted from the Pathology data base. Patients subjected to surgery with a diagnosis of GBP were identified in the Surgery data base. A single list was prepared and a review was made of the clinical histories, including, age, gender, clinical data, ultrasound report, and histopathology report. A total of 30 patients, with a median age of 51 years (range 22-83), 21 of whom were female, were included. The ultrasound diagnosis was GBP in 19 patients, GBP and calculi in 7 cases, and calculi with no polyps in 4 cases. Other diagnoses concurrent with GBP were multiple haemangiomas (3), large single simple cyst (1), and multiple simple cysts (1). Eleven patients had typical pain (biliary origin), 5 of which showed no calculi on ultrasound. Eight had non-specific pain, which persisted in 3 cases after the cholecystectomy. Pseudopolyps were found in 20 gallbladders, and true polyps in 4 cases. In 3 cases, polyps were not found in the pathology study. The ultrasound report must specify the size, shape, and number of polyps. Patients with biliary type pain would benefit from a cholecystectomy. The probability of malignancy is minimum if the GBP is less than 10mm and aged under 50 years, and a cholecystectomy is not required. A GBP greater than 10mm should be an indication of cholecystectomy. Copyright © 2011 AEC. Published by Elsevier España, S.L. All rights reserved.

    Perforating is a very common well completion operation. Usually, it is considered to be as simple as making holes in casing. Actually, perforating is one of the most critical tasks for establishing a path from reservoir rock to borehole form which hydrocarbons can flow to surface. The objective of this article is to relate perforating technology with geological aspects and completion type to determine the best shooting equipment (gun type, charge and differential pressure) to perform the most efficient perforating job. Several subjects related to formation geology are taken into account for a shooting job, such as: compressive strength, reservoir pressure and thickness, lithology type, porosity and permeability, ratio between horizontal and vertical permeabilities, and fluid type. Gun geometry used in the oil industry incorporates several parameters, including shot density, hole entrance diameter, gun phase and jet penetration. API tests are done on perforating guns to define applicability and performance. A new geometrical parameter is defined as the relative angle of the jet, which is the angle between the jet tunnel and formation dip. GEOCAN is a methodology which relates geology to gun geometry and type to define the most efficient gun system for perforated completions. It uses the intelligent perforating technique with the SPAN (Schlumberger Perforating Analysis) program to confirm optimum gun choice.

    AIM: To evaluate the impact of incidental gallbladder cancer on surgical experience. METHODS: Between 1998 and 2008 all cases of cholecystectomy at two divisions of general surgery, one university based and one at a public hospital, were retrospectively reviewed. Gallbladder pathology was diagnosed by history, physical examination, and laboratory and imaging studies [ultrasonography and computed tomography (CT)]. Patients with gallbladder cancer (GBC) were further analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. The primary endpoint was disease-free survival (DFS). The secondary endpoint was the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention. RESULTS: Nineteen patients (11 women and eight men) were found to have GBC. The male to female ratio was 1:1.4 and the mean age was 68 years (range: 45-82 years). Preoperative diagnosis was made in 10 cases, and eight were diagnosed postoperatively. One was suspected intraoperatively and confirmed by frozen sections. The ratio between incidental and nonincidental cases was 9/19. The tumor node metastasis stage was: pTis (1), pT1a (2), pT1b (4), pT2 (6), pT3 (4), pT4 (2); five cases with stage Ia (T1 a-b); two with stage Ib (T2 N0); one with stage IIa (T3 N0); six with stage IIb (T1-T3 N1); two with stage III (T4 Nx Nx); and one with stage IV (Tx Nx Mx). Eighty-eight percent of the incidental cases were discovered at an early stage (≤ II). Preoperative diagnosis of the 19 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases), gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case), porcelain gallbladder (one case), gallbladder adenoma (one case), and

    Medical and surgical disorders in pregnancy can be can be quite challenging for the obstetrician gynaecologist even in resource rich countries. Reaching an accurate diagnosis and admininstering appropriate management can be difficult in the presence of an on-going pregnancy. The importance of involving specialist from other disciplines (multidisciplinary care) cannot be overemphasized. We present an interesting case of perforated duodenal ulcer in a pregnant patient, review the literature ,discuss the differential diagnosis and evaluate the management principles for this rare condition.

    Pancreas divisum is a genetic defect associated with recurrent acute pancreatitis due to insufficient drainage of the accessory pancreatic duct. Seven young patients diagnosed with pancreatic divisum and thickening of the gallbladder bile as shown on magnetic resonance cholangio-pancreatography without pancreatic ductal changes underwent laparoscopic cholecystectomy. During the mean follow-up of 32 months no episode of pancreatitis was reported. There is an association between PD and higher concentration of bile in the gallbladder. Cholecystectomy can be considered curative in patients with PD in the absence of indications for major surgery. PMID:27938531

    The "effervescent gallbladder" sign, the sonographic finding of tiny echogenic foci rising from the dependent portion of the gallbladder, reminiscent of bubbles rising in a glass of champagne, has been reported previously as a finding of emphysematous cholecystitis. We report two additional cases of this unusual finding in an asymptomatic patient and in a patient with acute, gangrenous cholecystitis, confirmed in both cases by CT, to be secondary to the release of gas from gallstones. These two cases cast doubt on the sonographic sign as a pathognomonic finding of emphysematous cholecystitis.

    The authors report the case of 14-year-old girl with a history of myelomeningocele and previously shunt-treated hydrocephalus who presented with right-sided abdominal pain and subcutaneous emphysema that developed over a 1-week period. A CT scan of the patient's abdomen revealed a retained distal ventriculoperitoneal (VP) catheter with air tracking from the catheter to the upper chest wall. Given the high suspicion of the catheter being intraluminal, an exploratory laparotomy was performed and revealed multiple jejunal perforations. The patient required a partial small-bowel resection and reanastomosis for complete removal of the retained catheter. Six other similar cases of bowel perforation occurring in patients with abandoned VP and subdural-peritoneal shunts have been reported. The authors analyzed these cases with regard to age of presentation, symptomatic presentation, management, morbidity, and mortality. While there was 0% mortality associated with bowel perforation secondary to a retained distal VP catheter, the morbidity was significantly high and included peritonitis and small bowel resection.

    We encountered a case of localized IgG4-cholecystitis mimicking gallbladder cancer with focal/segmental type1 autoimmune pancreatitis (AIP). In this case, we were unable to exclude a diagnosis of gallbladder cancer and thus performed radical cholecystectomy. Type1 AIP is often associated with gallbladder lesions, accompanied by generally diffuse, circumferential thickening of the gallbladder wall. Although localized IgG4-related cholecystitis is extremely rare, differentiating this condition from gallbladder cancer is often very difficult.

    Pyometra, by definition, is a collection of purulent fluid within the uterine cavity. Incidence has been estimated to range from 0.1% to 0.5%. Typically, this is linked to postmenopausal women; however, it has been linked to premenopausal women with concordant use of intrauterine devices. Based on our knowledge, there have been less than 50 recorded cases reported in the English literature regarding perforation of pyometra resulting in acute abdomen and fewer than 25 resulting in pneumoperitoneum. We report a patient who was evaluated for diffuse peritonitis caused by perforated pyometra who was successfully treated with surgical intervention. PMID:28357145

    Due to the anatomical characteristics of the biliary tract, Ascaris lumbricoides rarely settles in the gallbladder, which makes biliary ascariasis a rare clinical condition. Ultrasonography plays a significant and practical role in the diagnosis and follow-up of suspected cases of biliary ascariasis. The 15-year-old case presented herein had been complaining of abdominal pain and dyspepsia for three months, and the clinical and laboratory findings for the patient indicated acute abdomen. Abdominal ultrasonography showed worms consistent with Ascaris inside a normal-sized gallbladder, dilated choledochus and the pancreatic duct. We started antiparasitic treatment in the patient, with cholangitis and pancreatitis diagnoses. Post-treatment follow-up ultrasonography showed a normal gallbladder, choledochus and pancreatic duct.

    Duplication of the gallbladder is a rare congenital anomaly of the gallbladder, with an estimated prevalence of 1–3 per 3800 individuals. Unless properly diagnosed preoperatively, it can lead to biliary tract injuries and postoperative complications which may require reoperative surgeries. While previously reported cases have been treated with conventional laparoscopic cholecystectomy (LC), treatment with single incision laparoscopic surgery (SILS) has not been reported yet. We herein present the case of a 58-year-old female with gallbladder duplication who was successfully treated with SILS cholecystectomy. PMID:26266074

    Productivity can be increased by prepacking perforations with gravel before a major gravel pack is pumped. The main gravel-pack treatment follows immediately after the prepack. This procedure can increase perforation permeability due to a more complete gravel fill of the perforation. The gravel pack prevents perforations from collapsing or filling with formation sand.

    Ulcer surgery and the epidemiology of peptic ulcer perforation have changed considerably in recent decades. Within two prospective studies, 170 perforated peptic ulcer patients from 12 Eastern European centres and 37 patients from 11 German centres were analysed. The median age of patients was 43 years in the Copernicus study and 49 years in the MEDWIS study (P=n.s.), being higher for MEDWIS female patients (73 vs 53 years, respectively; P<0.05). Female patients made up 17% (29/170) of the Copernicus study and 35% (40/170) of the MEDWIS study (P<0.05). Twenty-three per cent (40/170) of patients in the Copernicus study and 54% (20/37) in the MEDWIS study had gastric ulcer perforation (P<0.001). The proportion of definitive operations was higher in Eastern Europe (41.1%; 67/163) than it was in Germany (16.1%; 5/31) (P<0.01). German patients experienced more general complications than Eastern European patients (35 vs 12%, respectively; P<0.01) and a higher mortality [13% (5/37) vs 2% (4/170), respectively; P<0.01]. Delayed admission > or =12 h and age > or =60 years remained predictors for complications in multivariate logistic regression analysis. The proportion of both women and gastric ulcers was higher among German patients, while Eastern European patients underwent more definitive operations. German patients experienced more general complications and a higher mortality. Complications were related to high age and delayed admission.

    Metastatic melanoma is an aggressive disease that can spread to many organs of the body. In rare cases, it can spread to the gallbladder causing secondary lesions, yet presenting with little to no symptoms. Therefore, most cases of metastatic melanoma lesions to the gallbladder go undiagnosed. Here, we present the case of a 41-year-old male with a four-month history of melanoma of the face, with a postresection status, who presented with right upper quadrant abdominal pain. Doppler ultrasound and computed tomography confirmed the presence of a mass on the gallbladder. Laparoscopic excision along with liver wedge resection was performed. Pathology staining revealed the presence of a malignant metastatic melanoma lesion of the gallbladder. PMID:28251000

    Parastomal hernias can occur in up to 31% of patients following an enterostomy (Cheung in Aust N Z J Surg 65:808-811, 1995). This type of hernia develops through an intentional fascial defect. Commonly, most parastomal hernias involve a reducible segment of omentum, small bowel, or colon. Typically, these hernias are asymptomatic and associated rarely with strangulation or obstruction. Patient preference and clinical scenario may dictate management of these hernias. Non-operative management of parastomal hernias includes abdominal binders and enterostomy belts. Operative management includes a host of options including mesh repair, a new stoma site, or revision. This paper documents the first reported case of a parastomal hernia involving the gallbladder. Optimal technique and site placement of a stoma are also discussed.

    Gallbladder disease is common and, if managed incorrectly, can lead to high rates of morbidity, mortality, and extraneous costs. The most common complications of gallstones include biliary colic, acute cholecystitis, common bile duct stones, and gallstone pancreatitis. Ultrasound is the initial imaging modality of choice. Additional diagnostic and therapeutic studies including computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS), and endoscopic retrograde cholangiopancreatography (ERCP) are not routinely required but may play a role in specific situations. Biliary colic and acute cholecystitis are best treated with early laparoscopic cholecystectomy. Patients with common bile duct stones should be managed with cholecystectomy, either after or concurrent with endoscopic or surgical relief of obstruction and clearance of stones from the bile duct. Mild gallstone pancreatitis should be treated with cholecystectomy during the initial hospitalization to prevent recurrence. Emerging techniques for cholecystectomy include single-incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES). Early results in highly selected patients demonstrate the safety of these techniques. The management of complications of the gallbladder should be timely and evidence-based, and choice of procedures, particularly for common bile duct stones, is largely influenced by facility and surgeon factors.

    Background To develop a method for systematic classification of gallbladder stones, analyze the clinical characteristics of each type of stone and provide a theoretical basis for the study of the formation mechanism of different types of gallbladder stones. Methodology A total of 807 consecutive patients with gallbladder stones were enrolled and their gallstones were studied. The material composition of gallbladder stones was analyzed using Fourier Transform Infrared spectroscopy and the distribution and microstructure of material components was observed with Scanning Electron Microscopy. The composition and distribution of elements were analyzed by an X-ray energy spectrometer. Gallbladder stones were classified accordingly, and then, gender, age, medical history and BMI of patients with each type of stone were analyzed. Principal Findings Gallbladder stones were classified into 8 types and more than ten subtypes, including cholesterol stones (297), pigment stones (217), calcium carbonate stones (139), phosphate stones (12), calcium stearate stones (9), protein stones (3), cystine stones (1) and mixed stones (129). Mixed stones were those stones with two or more than two kinds of material components and the content of each component was similar. A total of 11 subtypes of mixed stones were found in this study. Patients with cholesterol stones were mainly female between the ages of 30 and 50, with higher BMI and shorter medical history than patients with pigment stones (P<0.05), however, patients with pigment, calcium carbonate, phosphate stones were mainly male between the ages of 40 and 60. Conclusion The systematic classification of gallbladder stones indicates that different types of stones have different characteristics in terms of the microstructure, elemental composition and distribution, providing an important basis for the mechanistic study of gallbladder stones.

    Strippings are problems that are frequent on thin and concave roots. Treatment and prognosis differ from that of a lateral root perforation because of the size, oval shape, and thin edges of the striping. We propose a two-step technique: an endodontic phase in which the root canal system is sealed with gutta-percha overflowing through the stripping perforation and a surgical second step that will allow elimination of this excess.

    2017-01-01

    Primary pure squamous cell carcinoma (SCC) of the gallbladder is an exceptionally rare type of tumor that comprises only 1% of all gallbladder cancer. SCC of the gallbladder portends a worse prognosis than the more common adenocarcinoma variant because of its aggressive invasion to local structures and because it is often diagnosed at an advanced stage. Owing to its rarity, diagnosis and management can be challenging. Herein, we present the case of a 75-year-old female complaining of abdominal pain, nausea, and vomiting. Computed tomography and ultrasonography results of the abdomen were consistent with acute cholecystitis and cholelithiasis. Histologic evaluation of the resected mass revealed a malignant tumor with prominent keratinization, confirming the diagnosis of an invasive primary pure SCC of the gallbladder. Microscopic examination showed direct infiltration to the liver, duodenum, and stomach. This case report describes the hospital course of a patient with SCC of the gallbladder and suggests that gallbladder cancer should be considered as part of the differential diagnosis in elderly patients presenting with acute cholecystitis. In addition, this article will review existing literature to examine the utility of different diagnostic techniques and treatment modalities available in the management of gallbladder cancer.

    Gallbladder cancer (GBC) is the fifth most common neoplasm of the gastrointestinal tract and the most common cancer of the biliary tract. GBC is suspected preoperatively in only 30-40% of patients. The other 60-70% are discovered incidentally (IGBC) by the pathologist on a gallbladder specimen following cholecystectomy for benign diseases such as polyps, gallstones, and cholecystitis. Between 1995 and 2011, 30 cases of GBC, who underwent resection with curative intent in our institutions, were retrospectively reviewed. They were analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. Overall survival, disease-free survival (DFS) and the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention were analyzed. The authors also present a systematic review to evaluate the role of extended surgery in the treatment of the incidental GBC. GBC was diagnosed in 30 patients, 16 women and 14 men. The M/F ratio was 1:1.14 and the mean age was 69.4 years (range 45-83 years). A preoperative diagnosis was possible only in 14 cases; fourteen of the incidental cases were diagnosed postoperatively after the pathological examination; two were suspected intraoperatively at the opening of the surgical specimen and then confirmed by frozen sections. The ratio between incidental and nonincidental cases was 1, 14/1, with twelve cases discovered after laparoscopic cholecystectomy. Eighty-one per cent of the incidental cases were discovered at an early stage (≤II). The preoperative diagnosis of the 30 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases); gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case); porcelain gallbladder (three

    Acute emphysematous cholecystitis is an uncommon condition caused by gas-forming organisms and characterized by the presence of gas in the wall and lumen of the gallbladder. Its incidence is higher among male diabetics. AEC in an elderly North American diabetic man with Indian ancestry is reported with a brief review of the world literature. The diagnosis was made preoperatively with the aid of plain radiographic films of the abdomen. A gangrenous distended gallbladder was removed at operation. Clostridium perfringens was cultured from the gallbladder contents and wall. If AEC is suspected, intensive antimicrobial therapy and fluid and electrolyte replacement should be given prior to early surgical intervention.

    Abstract Gallbladder polyps are most commonly treated with cholecystectomy, which is associated with various complications. For benign disease, preserving the gallbladder is preferable. Since 1994, we have been exploring percutaneous polypectomy and have recently developed an improved new technique. This study reports a new endoscopic-laparoscopic (Endolap) technique for the removal of polyps and the preservation of the gallbladder. Nine Chinese mini-pigs were used to observe mucosal regeneration. Microwaves of 50-70 mA for 9 seconds were safe, and the gallbladder mucosa of pigs recovered to nearly normal 2 weeks later. In the clinical cases, 60 patients with gallbladder polyps were studied. With the patient under general anesthesia, each polyp stem was coagulated, and then the polyp was removed. All procedures were successful at between 60 and 135 minutes. The success rate was 93.33% (56/60). A retrospective analysis was conducted to assess the recovery of gallbladder function. All patients were followed up and symptom-free, without recurrence of the polyps; 3 months after the operation, the volume and contraction of the gallbladder recovered to preoperative levels. Thus the Endolap technique is reliable for removing benign gallbladder polyps and is applicable to a wider range of clinical situations than percutaneous polypectomy.

    1991-01-01

    Duodenoscopic sphincterotomy (DS) is a well established treatment for common bile duct (CBD) stones in post-cholecystectomy patients, but not in patients with gallbladder in situ. The main argument against the procedure in the latter set of patients has been that by performing it, one is leaving behind the diseased gallbladder which may require further treatment. We have, however, performed 60 DS in 49 patients with gallbladder in situ. The clinical picture of these patients was characterized by abdominal pain in 79.6%, jaundice in 91.8%, history of cholangitis in 46.9%, severe acute cholangitis at the time of DS in 28.6% and a major associated illness in 10.2% of them. Adequate sphincterotomy was performed in 91.8% of the patients with successful stone extractions in 93.3% and an overall CBD clearance in 85.7%. One patient (2%) with severe acute cholangitis, who had presented in a moribund state, died despite adequate DS. Three patients (6%) experienced an exacerbation of acute cholangitis after DS, two of them requiring emergency surgery. During subsequent follow-up, elective cholecystectomy was performed in 26 (54%) patients. Five additional patients are awaiting surgery. Seventeen (36%) patients continue to have their gallbladders in situ and over a mean follow-up period of 12.8 months (range, 4-32 mos) they have remained asymptomatic except for brief episodes of biliary pain in 2 patients. It is concluded that DS relieves the symptoms of CBD stones even in patients with gallbladders in situ and may suffice for patients who are frail, elderly and who have major associated illnesses.

Esophageal perforation is a well-defined and severe clinical condition. There are several etiologies of esophagus perforation. We report the case of a 70-year-old Caucasian man who underwent an emergency cholecystectomy due to acute cholecystitis. Two days after surgery, his condition deteriorated. Thorax computerized tomography revealed an esophageal perforation. Esophageal perforation due to nasogastric application is relatively rare but the consequences are potentially serious. The anatomy of the upper gastrointestinal system should be understood by all healthcare professionals involved in the treatment.

    Background: Perforator flaps are well established, and their usefulness as freestyle island flaps is recognized. The whereabouts of vascular perforators and classification of perforator flaps in the face are a debated subject, despite several anatomical studies showing similar consistency. In our experience using freestyle facial perforator flaps, we have located areas where perforators are consistently found. This study is focused on a particular perforator lateral to the angle of the mouth; the modiolus and the versatile modiolus perforator flap. Methods: A cohort case series of 14 modiolus perforator flap reconstructions in 14 patients and a color Doppler ultrasonography localization of the modiolus perforator in 10 volunteers. Results: All 14 flaps were successfully used to reconstruct the defects involved, and the location of the perforator was at the level of the modiolus as predicted. The color Doppler ultrasonography study detected a sizeable perforator at the level of the modiolus lateral to the angle of the mouth within a radius of 1 cm. This confirms the anatomical findings of previous authors and indicates that the modiolus perforator is a consistent anatomical finding, and flaps based on it can be recommended for several indications from the reconstruction of defects in the perioral area, cheek and nose. Conclusions: The modiolus is a well-described anatomical area containing a sizeable perforator that is consistently present and readily visualized using color Doppler ultrasonography. We have used the modiolus perforator flap successfully for several indications, and it is our first choice for perioral reconstruction. PMID:27257591

    Perforation of the gastrointestinal system by a foreign body is seldom observed in clinical practice; however, it has great importance because it is preventable and can usually be easily treated. In this case report, we present a young male patient, who mistakenly swallowed a foreign body and presented to the emergency service one day later with acute abdomen. The 23-year-old patient was diagnosed with acute appendicitis and underwent emergency laparotomy. During the operation, a plastic object that perforated the terminal ileum lumen and protruded into the abdominal cavity was identified. Along with appendectomy, the foreign body was removed and the ileum was repaired. The detailed history of the patient revealed that he had mistakenly swallowed something one day before the onset of abdominal pain. The patient was discharged on the postoperative seventh day following an uneventful course. PMID:26170746

    Acute otitis externa, also known as 'swimmer's ear', is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

    Heterotopic pancreas is a rare entity. Thirty-three cases in the gallbladder have been reported. We describe the first case of heterotopic pancreas mimicking a gallbladder cancer, identified within a calcified lesion in the thickened posterior wall of the gallbladder. A 72-year-old woman with right upper quadrant pain was referred with a suspicion of gallbladder neoplasia. A CT scan demonstrated a 1 cm thickened posterior wall of the gallbladder with a 2 mm punctate calcification. An open cholecystectomy was carried out without complication. The frozen section demonstrated pancreatic tissue. Heterotopic pancreas of the gallbladder is highly uncommon. It can mimic a neoplastic process in the gallbladder, particularly in the context of calcification. Its malignant potential in the gallbladder is unknown, in contrast to previously described neoplastic transformation with gastric heterotopic pancreas.

    Perforated appendicitis is associated with an increased morbidity and length of stay. "Fast track" protocols have demonstrated success in shortening hospitalization without increasing morbidity for a variety of surgical processes. This study evaluates a fast track pathway for perforated appendicitis. In 2013, a treatment pathway for perforated appendicitis was adopted by the Acute Care Surgery Service for patients having surgical management of perforated appendicitis. Interval appendectomy was excluded. Patients were treated initially with intravenous antibiotics and transitioned to oral antibiotics and dismissed when medically stable and tolerating oral intake. A retrospective review of patients managed on the fast track pathway was undertaken to analyze length of stay, morbidity, and readmissions. Thirty-four males and twenty-one females with an average age of 46.8 years underwent laparoscopic appendectomy for perforated appendicitis between January 2013 and December 2014. Pre-existing comorbidities included hypertension 42%, diabetes mellitus 11%, COPD 5% and heart disease 2%. No patient had conversion to open appendectomy. Average length of stay was 2.67 days and ranged from 1 to 12 days (median 2 days). Postoperative morbidity was 20% and included abscess (6 patients), prolonged ileus (3 patients), pneumonia (1 patient), and congestive heart failure (1 patient). Five patients were readmitted for abscess (3 patients), congestive heart failure (1 patient), and pneumonia (1 patient). A fast track pathway for perforated appendicitis produced shorter length of stay and acceptable postoperative morbidity and readmission. This offers the potential for significant cost savings over current national practice patterns. Copyright © 2016 Elsevier Inc. All rights reserved.

    2015-01-01

    The outcome of gallbladder carcinoma is poor, and the overall 5-year survival rate is less than 5%. In early-stage disease, a 5-year survival rate up to 75% can be achieved if stage-adjusted therapy is performed. There is wide geographic variability in the frequency of gallbladder carcinoma, which can only be explained by an interaction between genetic factors and their alteration. Gallstones and chronic cholecystitis are important risk factors in the formation of gallbladder malignancies. Factors such as chronic bacterial infection, primary sclerosing cholangitis, an anomalous junction of the pancreaticobiliary duct, and several types of gallbladder polyps are associated with a higher risk of gallbladder cancer. There is also an interesting correlation between risk factors and the histological type of cancer. However, despite theoretical risk factors, only a third of gallbladder carcinomas are recognized preoperatively. In most patients, the tumor is diagnosed by the pathologist after a routine cholecystectomy for a benign disease and is termed ‘‘incidental or occult gallbladder carcinoma’’ (IGBC). A cholecystectomy is performed frequently due to the minimal invasiveness of the laparoscopic technique. Therefore, the postoperative diagnosis of potentially curable early-stage disease is more frequent. A second radical re-resection to complete a radical cholecystectomy is required for several IGBCs. However, the literature and guidelines used in different countries differ regarding the radicality or T-stage criteria for performing a radical cholecystectomy. The NCCN guidelines and data from the German registry (GR), which records the largest number of incidental gallbladder carcinomas in Europe, indicate that carcinomas infiltrating the muscularis propria or beyond require radical surgery. According to GR data and current literature, a wedge resection with a combined dissection of the lymph nodes of the hepatoduodenal ligament is adequate for T1b and T2

    Large differences in terms of incidence and mortality due to gallbladder cancer (GBC) have been reported worldwide. Moreover, it seems that GBC has unique characteristics in South America. We surveyed the literature looking for information about the epidemiology, basic and translational research, and clinical trials performed in South America in order to critically analyze the magnitude of this health problem in the region. Compared to other geographic areas, age-standardized mortality rates (ASMR) for GBC in women are very high, particularly in many western areas of South America. Genetic, as well as dietary and environmental factors likely contribute to the pathogenesis of this disease in the area. Compared to other regions the profile of abnormalities of key genes such as KRAS and TP53 in GBC seems to slightly differ in South America, while the clinical behavior appears to be similar with a median overall survival (OS) of 6.5 to 8 months in advanced GBC. In contrast to Europe and USA, prophylactic cholecystectomy is a common practice in western areas of South America. GBC particularly affects women in South America, and represents a significant public health problem. It appears to have peculiarities that pose an urgent need for additional research aimed to discover risk factors, molecular events associated with its development and new treatment options for this lethal disease.

  18. 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.

    AIM: To assess gallbladder emptying and its association with cholecystitis and abdominal pain in patients with primary sclerosing cholangitis (PSC). METHODS: Twenty patients with PSC and ten healthy subjects were investigated. Gallbladder fasting volume, ejection fraction and residual volume after ingestion of a test meal were compared in patients with PSC and healthy controls using magnetic resonance imaging. Symptoms, thickness and contrast enhancement of the gallbladder wall and the presence of cystic duct strictures were also assessed. RESULTS: Median fasting gallbladder volume in patients with PSC [67 (19-348) mL] was twice that in healthy controls [32 (16-55) mL] (P < 0.05). The median postprandial gallbladder volume in patients with PSC was significantly larger than that in healthy controls (P < 0.05). There was no difference in ejection fraction, gallbladder emptying volume or mean thickness of the gallbladder wall between PSC patients and controls. Contrast enhancement of the gallbladder wall in PSC patients was higher than that in controls; (69% ± 32%) and (42% ± 21%) (P < 0.05). No significant association was found between the gallbladder volumes and occurrence of abdominal pain in patients and controls. CONCLUSION: Patients with PSC have increased fasting gallbladder volume. Gallbladder Mucosal dysfunction secondary to chronic cholecystitis, may be a possible mechanism for increased gallbladder.

    2009-01-01

    Water transport across gallbladder epithelium is driven by osmotic gradients generated from active salt absorption and secretion. Aquaporin (AQP) water channels have been proposed to facilitate transepithelial water transport in gallbladder and to modulate bile composition. We found strong AQP1 immunofluorescence at the apical membrane of mouse gallbladder epithelium. Transepithelial osmotic water permeability (Pf) was measured in freshly isolated gallbladder sacs from the kinetics of luminal calcein self-quenching in response to an osmotic gradient. Pf was very high (0.12 cm/s) in gallbladders from wild-type mice, cAMP independent, and independent of osmotic gradient size and direction. Although gallbladders from AQP1 knockout mice had similar size and morphology to those from wild-type mice, their Pf was reduced by ∼10-fold. Apical plasma membrane water permeability was greatly reduced in AQP1-deficient gallbladders, as measured by cytoplasmic calcein quenching in perfluorocarbon-filled, inverted gallbladder sacs. However, neither bile osmolality nor bile salt concentration differed in gallbladders from wild-type vs. AQP1 knockout mice. Our data indicate constitutively high water permeability in mouse gallbladder epithelium involving transcellular water transport through AQP1. The similar bile salt concentration in gallbladders from AQP1 knockout mice argues against a physiologically important role for AQP1 in mouse gallbladder. PMID:19179619

    OBJECTIVE To examine bile acid composition of gallbladder contents in dogs with gallbladder mucocele and biliary sludge. ANIMALS 18 dogs with gallbladder mucocele (GBM group), 8 dogs with immobile biliary sludge (i-BS group), 17 dogs with mobile biliary sludge (m-BS group), and 14 healthy dogs (control group). PROCEDURES Samples of gallbladder contents were obtained by use of percutaneous ultrasound-guided cholecystocentesis or during cholecystectomy or necropsy. Concentrations of 15 bile acids were determined by use of highperformance liquid chromatography, and a bile acid compositional ratio was calculated for each group. RESULTS Concentrations of most bile acids in the GBM group were significantly lower than those in the control and m-BS groups. Compositional ratio of taurodeoxycholic acid, which is 1 of 3 major bile acids in dogs, was significantly lower in the GBM and i-BS groups, compared with ratios for the control and m-BS groups. The compositional ratio of taurocholic acid was significantly higher and that of taurochenodeoxycholic acid significantly lower in the i-BS group than in the control group. CONCLUSIONS AND CLINICAL RELEVANCE In this study, concentrations and fractions of bile acids in gallbladder contents were significantly different in dogs with gallbladder mucocele or immobile biliary sludge, compared with results for healthy control dogs. Studies are needed to determine whether changes in bile acid composition are primary or secondary events of gallbladder abnormalities.

    The muscle and epithelial tissues of the gallbladder are regulated by a ganglionated plexus that lies within the wall of the organ. Although these ganglia are derived from the same set of precursor neural crest cells that colonize the gut, they exhibit structural, neurochemical and physiological characteristics that are distinct from the myenteric and submucous plexuses of the enteric nervous system. Structurally, the ganglionated plexus of the guinea pig gallbladder is comprised of small clusters of neurons that are located in the outer wall of the organ, between the serosa and underlying smooth muscle. The ganglia are encapsulated by a shell of fibroblasts and a basal lamina, and are devoid of collagen. Gallbladder neurons are rather simple in structure, consisting of a soma, a few short dendritic processes and one or two long axons. Results reported here indicate that all gallbladder neurons are probably cholinergic since they all express immunoreactivity for choline acetyltransferase. The majority of these neurons also express substance P, neuropeptide Y, and somatostatin, and a small remaining population of neurons express vasoactive intestinal peptide (VIP) immunoreactivity and NADPH-diaphorase enzymatic activity. We report here that NADPH-diaphorase activity, nitric oxide synthase immunoreactivity, and VIP immunoreactivity are expressed by the same neurons in the gallbladder. Physiological studies indicate that the ganglia of the gallbladder are the site of action of the following neurohumoral inputs: 1) all neurons receive nicotinic input from vagal preganglionic fibers; 2) norepinephrine released from sympathetic postganglionic fibers acts presynaptically on vagal terminals within gallbladder ganglia to decrease the release of acetylcholine from vagal terminals; 3) substance P and calcitonin gene-related peptide, which are co-expressed in sensory fibers, cause prolonged depolarizations of gallbladder neurons that resemble slow EPSPs; and 4) cholecystokinin

    Incubation of (1-/sup 14/C)arachidonic acid (AA) with homogenates of bovine gallbladder muscle generated a large amount of radioactive material having the chromatographic mobility of 6-keto-PGF1 alpha (stable product of PGI2) and smaller amounts of products that comigrated with PGF2 alpha PGE2. Formation of these products was inhibited by the cyclooxygenase inhibitor indomethacin. The major radioactive product identified by thin-layer chromatographic mobility and by gas chromatography - mass spectrometric analysis was found to be 6-keto-PGF1 alpha. The quantitative metabolic pattern of (1-/sup 14/C)PGH2 was virtually identical to that of (1-/sup 14/C)AA. Incubation of arachidonic acid with slices of bovine gallbladder muscle released labile anti-aggregatory material in the medium, which was inhibited by aspirin or 15-hydroperoxy-AA. These results indicate that bovine gallbladder muscle has a considerable enzymatic capacity to produce PGI2 from arachidonic acid.

    The course of acalculous adenomyomatosis of the gallbladder in six patients is described. It is suggested that, even in the absence of gallstones, cholecystectomy should be advised when this condition is demonstrated radiographically in symptomatic subjects. The cause of the pain is unknown but it is probably related to excessive neuromuscular activity of the hyperplastic gallbladder wall. One of the patients was found also to have an adenomatous polyp containing areas of adenocarcinoma. Although this polyp was not situated within an area of adenomyomatosis, it is possible that, as in most other patients with carcinoma of the gallbladder, previous disease may have predisposed to malignant change.

    Objective. We evaluated whether routine ultrasound examination may illustrate gallbladder abnormalities, including acute acalculous cholecystitis (AAC) in the intensive care unit (ICU). Patients and Methods. Ultrasound monitoring of the GB was performed by two blinded radiologists in mechanically ventilated patients irrespective of clinical and laboratory findings. We evaluated major (gallbladder wall thickening and edema, sonographic Murphy's sign, pericholecystic fluid) and minor (gallbladder distention and sludge) ultrasound criteria. Measurements and Results. We included 53 patients (42 males; mean age 57.6 ± 2.8 years; APACHE II score 21.3 ± 0.9; mean ICU stay 35.9 ± 4.8 days). Twenty-five patients (47.2%) exhibited at least one abnormal imaging finding, while only six out of them had hepatic dysfunction. No correlation existed between liver biochemistry and ultrasound results in the total population. Three male patients (5.7%), on the grounds of unexplained sepsis, were diagnosed with AAC as incited by ultrasound, and surgical intervention was lifesaving. Patients who exhibited ≥2 ultrasound findings (30.2%) were managed successfully under the guidance of evolving ultrasound, clinical, and laboratory findings. Conclusions. Ultrasound gallbladder monitoring guided lifesaving surgical treatment in 3 cases of AAC; however, its routine application is questionable and still entails high levels of clinical suspicion.

    Ducts of Luschka are a developmental abnormality found within the gallbladder fossa in up to 10% of cholecystectomy specimens. They are most often encountered by surgeons when injured during laparoscopic or open cholecystectomy, leading to bile leakage and subsequent peritonitis. Histologically, they are typically composed of lobular aggregates of small ductules lined by bland, cuboidal-to-columnar biliary-type epithelium, associated with centrally located, larger ductules surrounded by concentric fibrosis. We have identified 6 cases of florid Luschka duct proliferation in which the ductules demonstrated irregular growth pattern, loss of characteristic concentric fibrosis, and epithelial atypia that strongly suggested the diagnosis of invasive pancreatobiliary adenocarcinoma or metastatic adenocarcinoma involving the gallbladder serosa. Two of the cases were initially diagnosed as invasive adenocarcinoma, whereas the other 4 were sent for consultation to rule out adenocarcinoma. All cases were associated with marked acute and chronic cholecystitis with mucosal ulceration, cholelithiasis, and thickening of the gallbladder wall. The ducts of Luschka were located within the rim of adherent liver in all 6 cases and the gallbladder serosa in 5 cases. Limited follow-up information was available for all patients with no documentation of progressive disease. Awareness and proper recognition of the anatomic location and histologic features are imperative in distinguishing florid ducts of Luschka from both non-neoplastic conditions and most importantly adenocarcinoma.

    2008-05-01

    It has recently been described that bradykinin B(2) receptors are expressed in the human gallbladder and that their activation induces a powerful contraction, especially in acute cholecystitis tissues. Here the role of the B(1) receptor in the contractility of control and inflamed human gallbladder was investigated. Strips of human gallbladder from either acute gallstone cholecystitis or elective gastro-entero-pancreatic surgery (control) were assessed in vitro and processed for reverse transcription-PCR analysis. Cumulative concentration-response curves with the selective B(1) receptor agonist, Lys-Des-Arg(9)-bradykinin, cholecystokinin and carbachol were performed in control and cholecystitis specimens. Lys-Des-Arg(9)-bradykinin concentration-dependently contracted strips of control gallbladders and its motor effect was higher in inflamed gallbladders. Lys-Des-Arg(9)-bradykinin-induced contraction was not altered by pretreatment with the selective bradykinin B(2) receptor antagonist, HOE140 (1 microM), the NK(1) (SR140333), NK(2) (SR48968) and NK(3) (SR142801) tachykinin receptor antagonists (all 1 microM), the muscarinic acetylcholine receptor antagonist, atropine (1 microM), and the cyclo-oxygenase inhibitor, indomethacin (5 microM). In contrast, the Lys-Des-Arg(9)-bradykinin-induced motor response was significantly reduced by the selective B(1) receptor antagonist, R-715. Finally, quantitative real-time PCR analysis indicated that B(1) receptor mRNA levels were significantly higher in cholecystitis smooth muscle specimens, when compared with that observed in control tissues. Bradykinin B(1) receptor has an important role as a spasmogen of human gallbladder, and selective antagonists of the B(1) receptor may represent a valid therapeutic option to control pain in patients with acute cholecystitis.

  8. Perforated diode neutron sensors

    McNeil, Walter J.

    A novel design of neutron sensor was investigated and developed. The perforated, or micro-structured, diode neutron sensor is a concept that has the potential to enhance neutron sensitivity of a common solid-state sensor configuration. The common thin-film coated diode neutron sensor is the only semiconductor-based neutron sensor that has proven feasible for commercial use. However, the thin-film coating restricts neutron counting efficiency and severely limits the usefulness of the sensor. This research has shown that the perforated design, when properly implemented, can increase the neutron counting efficiency by greater than a factor of 4. Methods developed in this work enable detectors to be fabricated to meet needs such as miniaturization, portability, ruggedness, and adaptability. The new detectors may be used for unique applications such as neutron imaging or the search for special nuclear materials. The research and developments described in the work include the successful fabrication of variant perforated diode neutron detector designs, general explanations of fundamental radiation detector design (with added focus on neutron detection and compactness), as well as descriptive theory and sensor design modeling useful in predicting performance of these unique solid-state radiation sensors. Several aspects in design, fabrication, and operational performance have been considered and tested including neutron counting efficiency, gamma-ray response, perforation shapes and depths, and silicon processing variations. Finally, the successfully proven technology was applied to a 1-dimensional neutron sensor array system.

    Our objective is to describe the characteristic CT findings of gastrointestinal (GI) tract perforations at various levels of the gastrointestinal system. It is beneficial to localize the perforation site as well as to diagnose the presence of bowel perforation for planning the correct surgery. CT has been established as the most valuable imaging technique for identifying the presence, site and cause of the GI tract perforation. The amount and location of extraluminal free air usually differ among various perforation sites. Further, CT findings such as discontinuity of the bowel wall and concentrated free air bubbles in close proximity to the bowel wall can help predict the perforation site. Multidetector CT with the multiplanar reformation images has improved the accuracy of CT for predicting the perforation sites. PMID:19182505

    Obesity has become a global health issue because of its increased morbidity and mortality, and a close association with at least 20 different cancers. Clinical and epidemiological studies have suggested that obesity and overweight are positively related with the risk of GBC. Gallbladder cancer (GBC) is a relatively infrequent but highly lethal neoplasm. Obesity may disturb lipid and endogenous hormones metabolism, affect gallbladder motility, increase the risk of gallstones, and thus plays a role in GBC. Control of obesity through measures such as lifestyle modification, healthy diet, and regular exercise may prove useful in the prevention of GBC.

Although the pathogenesis is incompletely defined, an altered motility of the gallbladder may contribute to the increased risk of gallstones during pregnancy. Methods We measured gallbladder volume using real-time ultrasonography to find out the mechanism for the changes of gallbladder motility during late pregnancy. Eighteen pregnant women took the gallbladder ultrasonography during their last trimester of pregnancy and after delivery: gallbladder volume and ejection fraction were calculated in each patient. Results Fasting gallbladder volumes increased significantly in the last trimester of pregnancy (25.28± 14.26ml) compared with postpartum (17.44±5.82ml) (p<0.05). Gallbladder volumes measured after fatty meals showed more increment in pregnant women (10.13±7.19ml) than in those after delivery (4.34±3.36ml) (p<0.005). A significantly reduced gallbladder ejection fraction was found in the pregnant group (60.56± 18.80%) compared with those after delivery (77.48± 13.37%) (p<0.005). Conclusion Gallbladder motility in late pregnancy shows significant impairment compared with that in postpartum. Thus, we suggest that gallbladder hypomotility may occur during late pregnancy, and this impairment of gallbladder motility may play an important role in gallstone formation. PMID:9159032

    Intravenous injection of indocyanine green (ICG) is used to illuminate extrahepatic biliary anatomy. Fluorescence of biliary structures may lower surgical complications that can arise due to inadvertent injury to the common bile duct. We describe a method of injecting ICG directly into the gallbladder to define the cystic duct and common bile duct anatomy. A standard laparoscopic cholecystectomy was performed using a laparoscope with near-infrared imaging capability. Before dissection, the gallbladder was punctured with a cholangiogram catheter or a pigtail catheter to aspirate the bile within the gallbladder. The aspirated bile is mixed with ICG solution, which is reinjected into the gallbladder to fluoresce the gallbladder, cystic duct, and common bile duct structures. Eleven patients underwent direct gallbladder ICG injection for fluorescence cholangiography during cholecystectomy. Direct gallbladder ICG injection clearly defined the extrahepatic biliary anatomy, including the cystic duct-common bile duct junction, by fluorescence. In addition, the dissection plane between the gallbladder and the liver is highlighted with the gallbladder ICG fluorescence. Direct gallbladder ICG injection provides immediate visualization of extrahepatic biliary structures and clarifies the dissection plane between the gallbladder and the liver bed.

    Spontaneous perforation of a duodenal diverticulum is a rare but serious complication with significant mortality rates. Just over 100 cases have been reported in the world literature. One case of perforated duodenal diverticulum treated by simple closure is reported. An elderly female was admitted to our hospital with an acute abdomen. Computed tomography of the abdomen showed retroperitoneal air around the duodenum and right kidney. Laparotomy with a Kocher maneuver disclosed a perforated diverticulum in the second portion of the duodenum. Although diverticulectomy is the most common treatment, simple closure of the perforated duodenal diverticulum with drainage was performed to avoid injury to the distal common bile duct and ampulla of Vater, which were close to the diverticulum. The patient has fully recovered and has been asymptomatic with no signs of recurrence for 25 months.

    Gallbladder cancer is a lethal disease with notable geographical variations worldwide and a predilection towards women. Its main risk factor is prolonged exposure to gallstones, although bacterial infections and other inflammatory conditions are also associated. The recurrent cycles of gallbladder epithelium damage and repair enable a chronic inflammatory environment that promotes progressive morphological impairment through a metaplasia-dysplasia-carcinoma, along with cumulative genome instability. Inactivation of TP53, which is mutated in over 50% of GBC cases, seems to be the earliest and one of the most important carcinogenic pathways involved. Increased cell turnover and oxidative stress promote early alteration of TP53, cell cycle deregulation, apoptosis and replicative senescence. In this review, we will discuss evidence for the role of inflammation in gallbladder carcinogenesis obtained through epidemiological studies, genome-wide association studies, experimental carcinogenesis, morphogenetic studies and comparative studies with other inflammation-driven malignancies. The evidence strongly supports chronic, unresolved inflammation as the main carcinogenic mechanism of gallbladder cancer, regardless of the initial etiologic trigger. Given this central role of inflammation, evaluation of the potential for GBC prevention removing causes of inflammation or using anti-inflammatory drugs in high-risk populations may be warranted.

    Gallbladder cancer is usually diagnosed at a late stage and generally results in death. Discovery of predisposing factors for this neoplasia could prevent this outcome. In this study, we assess the presence of one of these factors: intestinal metaplasia in gallbladders with stones and inflammatory processes. Cross-sectional study in Hospital do Servidor Público Estadual de São Paulo. The first 80 gallbladders from patients who underwent elective cholecystectomy between April and August 2002, presenting stones and chronic inflammation, were studied. The patients were divided into groups according to their age: CC1, from 15 to 40 years; CC2, from 41 to 60 years; and CC3, from 61 to 85 years. Twenty-one patients (26%) were male, while 59 (74%) were female. In the group CC1, intestinal metaplasia was present in 85.71% of the 21 patients studied; in CC2, in 79.41% of 34 patients; and in CC3, in 56.00% of 25 patients. These differences presented statistical significance (p = 0.04542). Intestinal metaplasia is extremely frequent in gallbladders with inflammation and lithiasis, especially in younger patients.

    Cystoisospora belli, previously known as Isospora belli, is an obligate intracellular coccidian parasite that is most often associated with gastrointestinal disease in immunocompromised patients. In this study, we detail the clinicopathologic features of 18 cases of Cystoisospora infection affecting the gallbladder in immunocompetent individuals and compare them with a control group. Each case was reviewed for cholecystitis (none, acute, chronic), epithelial disarray, presence of intraepithelial lymphocytes (none, rare [≤5 per 20 epithelial cells], present [>5 per 20 epithelial cells]), architectural distortion, intramucosal eosinophilia, and mural thickening/serositis. The mean age of patients with Cystoisospora infection was 33 years and the male to female ratio 1:4.3. Cholecystectomy was performed for biliary dyskinesia (n=7), abdominal pain (n=7), suspected cholelithiasis (n=5), and cholecystitis (n=3). In 2 cases, Cystoisospora was found in donor gallbladders resected at the time of liver transplantation. Each case was characterized by eosinophilic, oval or banana-shaped intraepithelial parasites within perinuclear parasitophorous vacuoles. Most cases showed epithelial disarray and minimal intraepithelial lymphocytosis. Of the 11 cases with an average follow-up of 15 months, none had evidence of disease related to Cystoisospora infection within the biliary tract or elsewhere in the gastrointestinal tract. We present the largest series of gallbladder cystoisosporiasis in immunocompetent patients to date. Cystoisospora infection is underrecognized in the gallbladders of immunocompetent patients, in part due to the subtle findings in routine cholecystectomy specimens. On the basis of the clinical follow-up, gallbladder cystoisosporiasis in immunocompetent individuals appears to be a self-limited infection.

    A 59-year-old man presented with abdominal and left flank pain. The symptom had started 30 days before as an acute nephrolithiasis, which had worsened despite conservative management. The abdomen was slightly distended and tender over the lower abdomen, without signs of generalized peritoneal irritation. A computed tomography (CT) scan showed an abscess in left para-renal space up to the subphrenic space and an unexpected pneumomediastinum. An emergency operation was performed, which showed retroperitoneal diverticulitis perforation of the sigmoid descending junction with abscess formation. A segmental resection of the diseased colon and end-colostomy was performed (Hartmann's procedure). However, the patient's condition progressively deteriorated, and he died of sepsis and multi-organ failure on the 5th postoperative day. Although pneumomediastinum caused by colonic diverticulitis perforation is extremely rare, it could be a life-threatening condition in patients without signs of peritonitis because of delayed diagnosis.

    We report the case of an 18-year-old female patient with no past medical history who presented to the emergency department with acute abdominal pain and vomiting on the background of a long history of ingesting hair (trichophagia). Computed tomography revealed pneumoperitoneum and free fluid in keeping with visceral perforation. In addition, a large hair bolus was seen extending in contiguity from the stomach to the jejunum. A laparotomy was performed, revealing an anterior gastric perforation secondary to a 120cm long trichobezoar, which had formed a cast of the entire stomach, duodenum and proximal jejunum. The bezoar was removed and an omental patch repair to the anterior ulcer was performed. The patient made an excellent postoperative recovery and was discharged home with psychiatric follow-up review.

    Pathological rates of gallbladder salt and water transport may promote the formation of cholesterol gallstones. Because prairie dogs are widely used as a model of this event, we characterized gallbladder ion transport in animals fed control chow by using electrophysiology, ion substitution, pharmacology, isotopic fluxes, impedance analysis, and molecular biology. In contrast to the electroneutral properties of rabbit and Necturus gallbladders, prairie dog gallbladders generated significant short-circuit current (I(sc); 171 +/- 21 microA/cm(2)) and lumen-negative potential difference (-10.1 +/- 1.2 mV) under basal conditions. Unidirectional radioisotopic fluxes demonstrated electroneutral NaCl absorption, whereas the residual net ion flux corresponded to I(sc). In response to 2 microM forskolin, I(sc) exceeded 270 microA/cm(2), and impedance estimates of the apical membrane resistance decreased from 200 Omega.cm(2) to 13 Omega.cm(2). The forskolin-induced I(sc) was dependent on extracellular HCO(3)(-) and was blocked by serosal 4,4'-dinitrostilben-2,2'-disulfonic acid (DNDS) and acetazolamide, whereas serosal bumetanide and Cl(-) ion substitution had little effect. Serosal trans-6-cyano-4-(N-ethylsulfonyl-N-methylamino)-3-hydroxy-2,2-dimethyl-chroman and Ba(2+) reduced I(sc), consistent with the inhibition of cAMP-dependent K(+) channels. Immunoprecipitation and confocal microscopy localized cystic fibrosis transmembrane conductance regulator protein (CFTR) to the apical membrane and subapical vesicles. Consistent with serosal DNDS sensitivity, pancreatic sodium-bicarbonate cotransporter protein pNBC1 expression was localized to the basolateral membrane. We conclude that prairie dog gallbladders secrete bicarbonate through cAMP-dependent apical CFTR anion channels. Basolateral HCO(3)(-) entry is mediated by DNDS-sensitive pNBC1, and the driving force for apical anion secretion is provided by K(+) channel activation.

    Duodenal ulcer perforation in pediatric age group is an uncommon entity; hence, it is not usually considered in the differential diagnosis of acute abdomen in these patients. It is important for the emergency physician to consider perforated peptic ulcer in the differential diagnosis of children presenting with acute abdominal pain, gastrointestinal bleeding, or shock. We report a 6½-year-old male child with thalassemia major who presented to emergency room with an acute abdomen and shock, who was subsequently found to have a perforated duodenal ulcer, probably related to use of oral chelating agent, deferasirox. Although, gastrointestinal symptoms like nausea, vomiting, and abdominal pain has been mentioned as infrequent adverse event in the scientific product information of deferasirox, in our current knowledge this is the first case report of perforated duodenal ulcer after oral deferasirox. The severity of this event justifies the reporting of this case. This patient had an atypical presentation in that there were no signs or symptoms of peptic ulcer disease before perforation and shock he was successfully managed with open surgery after initial resuscitation and stabilization of his general condition.

    The authors describe radiologic findings in five patients with spontaneous perforation of the common bile duct (a rare disorder). The patients were 5 weeks, 9 weeks, 3 months, 11 months, and 2 1/2 years old at presentation. The most common presenting complaints were jaundice and abdominal distention (due to ascites). Sonographic findings included ascites in three patients, a loculated fluid collection around the gallbladder in two patients, and both in one patient. The biliary tree was undilated in all patients. Results of hepatobiliary scintigraphy definitely demonstrated that intraperitoneal fluid originated from the biliary tract. Intraoperative cholangiography was used to confirm the diagnosis at surgery. All children were successfully treated with surgery. Recognition of these findings on sonograms and subsequent confirmation with scintigraphy are important to prevent delays in diagnosis of a potentially fatal condition.

    Background/Aims Gallstone pathogenesis is linked to mucin hypersecretion and bacterial infection. Several mucin genes have been identified in gallbladder epithelial cells (GBECs). We investigated MUC expression in cholesterol-associated gallbladder disease and evaluated the relationship between mucin and bacterial infection. Methods The present study involved 20 patients with cholesterol stones with cholecystitis, five with cholesterol stones with cholesterolosis, six with cholesterol polyps, two with gallbladder cancer, and six controls. Canine GBECs treated with lipopolysaccharide were also studied. MUC3, MUC5AC, MUC5B, and MUC6 antibodies were used for dot/slot immunoblotting and immunohistochemical studies of the gallbladder epithelial tissues, canine GBECs, and bile. Reverse-transcription polymerase chain reaction was performed to evaluate MUC3 and MUC5B expression. Results MUC3, MUC5AC, MUC5B, and MUC6 were expressed in the normal gallbladder epithelium, and of those, MUC3 and MUC5B exhibited the highest expression levels. Greatly increased levels of MUC3 and MUC5B expression were observed in the cholesterol stone group, and slightly increased levels were observed in the cholesterol polyp group; MUC3 and MUC5B mRNA was also upregulated in those groups. Canine GBECs treated with lipopolysaccharide also showed upregulation of MUC3 and MUC5B. Conclusions The mucin genes with the highest expression levels in gallbladder tissue in cholesterol-associated diseases were MUC3 and MUC5B. Cholesterol stones and gallbladder infections were associated with increased MUC3 and MUC5B expression. PMID:27563024

    higher than in GB-SOV (35.5% vs 10%; p = 0.05). Nongranulomatous inflammation with fibrinoid necrosis of medium-sized vessels occurred equally in both groups (>90%). Forms of SV affecting the gallbladder included polyarteritis nodosa (n = 10), hepatitis B virus-associated vasculitis (n = 8), cryoglobulinemic (essential or hepatitis C virus-associated) vasculitis (n = 6), vasculitis associated with autoimmune diseases (n = 6), microscopic polyangiitis (n = 4), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (n = 4), IgA vasculitis (Henoch-Schönlein) (n = 2), and giant cell arteritis (n = 1).GV is uncommon. Its histology most often consists of a nongranulomatous necrotizing vasculitis affecting medium-sized vessels. GB-SOV is usually discovered after routine cholecystectomy performed because of the presence of local symptoms, gallstone-associated cholecystitis, and contrary to GB-SV, GB-SOV is usually not associated with systemic symptoms. Acute phase reactants and surrogate markers of autoimmunity are usually normal or negative in GB-SOV. GB-SOV does not require systemic antiinflammatory or immunosuppressive therapy; surgery is adequate to achieve cure. GB-SV always warrants immunosuppressant therapy and is associated with high mortality. The finding of GV may precede the generalized manifestations of SV. Therefore, once GV is discovered, studies to determine disease extent and a vigilant follow-up are mandatory.

    Proteins of S100 group, produced by phagocytes represent endogenous activators of innate immune responses. Role of these proteins in the etiopathogenesis of cholelithiasis remains unknown. The studies aimed at the morphometric evaluation of S100A8 and S100A9 protein expression in gallbladder mucosa in patients with acute and chronic calculous cholecystitis (n = 71). The presence of proteins was detected by immunohistochemistry while quantitative analysis employed the spatial visualization technique. We found the immunopositive expression of the two studied S100 proteins in neutrophils and monocytes/macrophages of the gallbladder's wall and a higher expression in acute cholecystitis. Quantitative study revealed higher immunoexpression of S100A9 over S100A8 in both studied groups of patients. Moreover, a reciprocal linear relationship between the expression of the studied proteins and a positive correlation between expression of either S100A8 or S100A9 and inflammatory activity (grading) in the gallbladder wall were found. The expression of S100A8 protein in the chronic cholecystitis group and in older patients correlated with leukocytosis, which suggests the role of S100A8 particularly at the chronic stage of cholecystitis. The obtained results indicated close relationship between S100A8 and S100A9 proteins in their proinflammatory functions. The increased expression of only one of them can be recognized as a useful index of local inflammatory activity in calculous cholecystitis.

    Perforations of the gastrointestinal tract have many causes. Holes in the wall of gastrointestinal organs can be created by blunt or penetrating trauma, iatrogenic injury, inflammatory conditions that penetrate the serosa or adventitia, extrinsic neoplasms that invade the gastrointestinal tract, or primary neoplasms that penetrate outside the wall of gastrointestinal organs. This article provides a radiologic approach for investigating the wide variety of gastrointestinal perforations. General principles about contrast agents and studies are reviewed, and then perforations in specific gastrointestinal organs are discussed.

    1981-08-01

    To define the role of ultrasound in evaluating acute right upper quadrant pain, a prospective study was performed on 52 patients having clinically suspected acute cholecystitis. Ultrasonographic determination of acute or chronic cholecystitis, or diagnosis of a normal gallbladder, was based on analysis of location of tenderness, calculi, sludge, and wall thickness. The diagnosis of acute cholecystitis (34.6% of patients) was based on the highly significant observations of focal gallbladder tenderness and calculi. Sludge and wall thickening were also statistically significant, but to a lesser degree. Cholelithiasis allowed differentiation of patients with chronic cholecystitis (32.7%) from patients with normal gallbladders (32.7%). Neither of these two groups had significant focal gallbladder tenderness, sludge, or thickened walls. Because acute cholecystitis is found in the minority of patients with acute right upper quadrant pain, and because ultrasound is rapid, accurate, and noninvasive, it should be the initial modality used to evaluate these patients.

  15. Effects of pregnancy and contraceptive steroids on gallbladder function.

    1980-02-14

    We used real-time ultrasonography to study gallbladder kinetics in 11 nonpregnant women, 17 women using steroid contraceptives, and 33 pregnant women. Gallbladder volume was determined after an overnight fast and serially for 90 minutes after a standard liquid meal. After the first trimester of pregnancy, gallbladder volume during fasting and residual volume after contraction were twice as large as in control subjects. The rate of emptying and the percentage emptied were reduced. In early pregnancy the only important abnormality was a 30 per cent decrease in emptying rate. Gallbladder function was not affected by contraceptive steroids. Incomplete empyting of the gallbladder in late pregnancy leaves a large residual volume and may cause retention of cholesterol crystals, a prerequisite for cholesterol-gallstone formation. These findings are consistent with the view that pregnancy increases the risk of cholesterol gallstones. The increased incidence of gallstones associated with contraceptive steroids does not involve abnormal gallbladder kinetics.

    Gallbladders are common specimens in routine histopathological practice and there are, at least in the United Kingdom and Australia, national guidance on how to sample gallbladders without macroscopically-evident, focal lesions/tumours (hereafter referred to as non-tumorous gallbladders).(1) Nonetheless, this author has seen considerable variation in the numbers of blocks used and the parts of the gallbladder sampled, even within one histopathology department. The recently re-issued 'Tissue pathways for gastrointestinal and pancreatobiliary pathology' from the Royal College of Pathologists (RCPath), first recommends sampling of the cystic duct margin and "at least one section each of neck, body and any focal lesion".(1) This recommendation is referenced by a textbook chapter which itself proposes that "cross-sections of the gallbladder fundus and lateral wall should be submitted, along with the sections from the neck of the gallbladder and cystic duct, including its margin".(2) This article is protected by copyright.

  17. [The application of digestive endoscopic ultrasonography in the gallbladder pathology].

    PubMed

    Roseau, Gilles

    2004-08-28

    A WELL DEFINED PATHOLOGY: Bilary lithiasis and vesicular parietal abnormalities constitute the totality of the gallbladder pathology. The surgical experience and widely current use of digestive imaging, notably ultrasonography, have contributed to enlightening our knowledge of this pathology. POTENTIAL DIAGNOSTIC PROBLEMS: There is no particular problem in the diagnosis of gallbladder lithiasis and its treatment is currently codified. However the discovery of thickened gallbladder wall or polyps increases the fear of gallbladder cancer. A FUNDAMENTAL ROLE FOR ENDOSCOPIC ULTRASONOGRAPHY: Within the framework of screening for cancer, endoscopic ultrasonography, the performance of which in gallbladder pathology has rarely been studied, appears promising. Other than its role in the control of the extension of gallbladder cancers, it provides reliable characterisation of most of the polyps. Hence its place today is unavoidable in the therapeutic decision trees of such affections.

  18. Pulse Granulomas of the Gastrointestinal Tract and Gallbladder: Report of Five Cases

    Hyaline rings with admixed multinucleated giant cells characterize pulse granulomas; the term pulse refers to edible seeds of legume vegetables. The etiology has been controversial, with theories including vascular degenerative changes or a reaction to vegetable material; ultrastructural studies and experimentally induced lesions in animals favor the latter. This lesion is typically seen in the oral cavity, with only rare reports in the gastrointestinal tract and gallbladder. We herein describe five cases of pulse granulomas identified in these sites. All cases contained foreign-body giant cells and vegetable debris within or near hyaline rings. Pulse granulomas may form mass lesions but are usually an incidental finding on microscopic examination. In incidentally detected cases, recognition of pulse granulomas can suggest a mural abscess, fistula, or perforation of the gut, findings which may not be grossly apparent. The presence of vegetable material in all five cases further supports an exogenous pathogenesis. PMID:28785500

    Introduction: Gallbladder tuberculosis, in an endemic region, is a common infectious etiology affecting a rare organ. The high prevalence of carcinoma gallbladder in the endemic regions of tuberculosis, like India, poses diagnostic dilemma. Case series: We are reporting three cases of gallbladder tuberculosis mimicking carcinoma gallbladder of which the first two cases were operated with a presumptive diagnosis of malignancy. The third case presented to us after laparoscopic cholecystectomy elsewhere and on evaluation was found to have disseminated tuberculosis. Discussion: The lack of pathognomonic clinical and radiological characters results in histological surprise of gallbladder tuberculosis following surgery performed for other indications like malignancy. In preoperatively diagnosed patients medical management plays pivotal role in management. Surgery is required in symptomatic patients. On the other hand, histologically proven cases following surgical resection require antitubercular therapy. Conclusion: Previous history of tuberculosis or concomitant tuberculosis at other sites may provide clue to the diagnosis of biliary tuberculosis. Antitubercular treatment after surgery plays an important role in preventing further dissemination. PMID:28386408

    Experiments were done to test the hypothesis that emptying the gallbladder prior to intravenous cholangiography (IVC) would result in earler and better opacification of the gallbladder. Five dogs were studied on two separate days in a crossover experiment. Each dog had a standard IVC (15-minute infusion of meglumine iodipamide) 2.5 cc/kg of following a 14-16-hour fasting period. On one of the days, 0.3 mcg/kg of Ceruletide was intramuscularly administered to each dog 30 to 45 minutes prior to the iodipamide infusion. Films obtained at the end of infusion and at 20, 40, 60, and 90 minutes were evaluated independently by three radiologists. The results indicate that pretreatment with Ceruletide produces a significant (p less than 0.05) improvement in the quality of gallbladder opacification during the first 90 minutes following iodipamide infusion. We conclude that earlier and better opacification of the gallbladder during IVC can be obtained by prior emptying of the gallbladder with a cholecystokinetic agent.

    The purpose of the study was to evaluate alanine transaminase (ALT) and gallbladder wall abnormalities as possible biomarkers for anaphylaxis in dogs presented for acute hypersensitivity reactions. Pilot study. A private practice, small animal, 24-hour emergency and specialty hospital. Ninety-six dogs presenting 101 times on an emergency basis for hypersensitivity reactions from March 2007 through March 2009. Veterinarians acquired a history, physical exam, serum chemistry panel, blood pressure, and ultrasound image of the gallbladder. Dogs were then divided into 2 groups: dogs fulfilling the definition for anaphylaxis (moderate and severe systemic hypersensitivity) and dogs that did not fulfill the definition and were classified as allergic reactions (local hypersensitivity and mild systemic hypersensitivity). Elevated ALT was significantly associated with anaphylaxis (P<0.001). Increased gallbladder wall thickness and a striated wall pattern were significantly associated with anaphylaxis (P<0.001) and these changes were readily apparent to first-responder veterinarians. Decreased body temperature (P<0.001) and hypothermia (P=0.006) were significantly associated with anaphylaxis. There was no significant difference between groups regarding age, heart rate, or presence of respiratory signs. Lower blood pressure was significantly associated with anaphylaxis (P<0.001) but hypotension was not significantly different (P=0.09) between groups. Cutaneous signs were significantly associated with the allergic reactions group (P<0.001) and, when seen with anaphylaxis, were subtle. This study showed an elevated ALT and an abnormal gallbladder wall to be biomarkers significantly associated with anaphylaxis in dogs with acute hypersensitivity reactions.

    Perforation of gastric cancer is rare and it accounts for less than 1% of the incidences of an acute abdomen. In this study, we reviewed cases of benign or malignant gastric perforation in terms of the accuracy of diagnosis and investigated the clinical outcome after emergency surgery in patients with a free perforation caused by gastric cancer. On the basis of pathological examination, gastric cancer was diagnosed in 8 patients and benign ulcer perforation in 32 patients. The sensitivity, specificity and accuracy of intraoperative diagnosis by pathological examination were 50, 93.8 and 85%, respectively. Except for age, there were no differences in the other demographic characteristics between patients with gastric cancer and benign ulcer perforation. The median survival time of patients with perforated gastric cancer was 195 days after surgery. Patients with gastric cancer perforation had a poorer overall survival rate than those who had T3 tumors without perforation. In addition, in patients with perforation, recurrence of peritoneum occurred more frequently. In conclusion, to improve the survival rate of patients with perforated gastric cancer and to improve the accuracy of intraoperative diagnosis, endoscopic examination and/or pathological examination of the frozen section should be performed, if possible. A balanced surgical strategy using laparoscopic local repair as the first-step of surgery, followed by radical open gastrectomy with lymphadenectomy may be considered.

    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.

    The diagnosis of blunt injury to the gallbladder may constitute a significant challenge to the diagnostician. There is often a delay in presentation with non-specific clinical symptoms. In the absence of reliable clinical symptoms, diagnostic imaging becomes an invaluable tool in the rapid identification of gallbladder injury. We present a case of isolated gallbladder injury following blunt abdominal trauma which was diagnosed by computed tomography and subsequently confirmed by cholecystectomy.

    Introduction At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. Presentation of case A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. Discussion The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Conclusion Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    The conventional pedicled sternocleidomastoid (SCM) flap has a poor arc of rotation, limited volume and precarious vascularity. This report describes a new technique for raising a SCM flap based on the perforating vessels of the superior thyroid vascular pedicle. The upper and lower attachments of the sternocleidomastoid muscle are divided. Four medically and/or surgically compromised patients have successfully undergone reconstruction of hemiglossectomy (1), partial glossectomy (1) and rim of mandible (2) defects for malignancy. The arc of rotation of the SCM flap is greatly increased and the potential applications for the flap expanded.

    Adenomyomatosis of the gallbladder is a benign, mostly asymptomatic condition of an unknown aetiology. Hyperplastic changes in the gallbladder wall cause an overgrowth of the mucosa, thickening of the muscular wall, and formation of intramural diverticula or sinus tracts termed Rokitansky-Aschoff sinuses. Adenomyomatosis is divided on general, segmental and localised. Ultrasound examination, computerized tomography and magnetic resonance are used in diagnostic procedure. The importance of the disease lies in the fact that it can cause recurrent right upper quadrant pain so it must be concerned in resolving pain cause. This paper was aimed at explaining the aetiology of the disease, its clinical manifestation, making diagnosis and therapy in order to make its diagnosis and treatment possible.

    Although exfoliative dermatitis (erythroderma) secondary to malignancy is commonly associated with lymphomas or leukemias, coincident gastrointestinal (GI) malignancy and erythroderma is rare. The authors recently encountered a patient with gallbladder carcinoma presenting as erythroderma. A 77-yr-old Japanese man presented with a 3-mo history of erythematous eruptions with pruritus over almost the entire body. After confirming the diagnosis of erythroderma, asymptomatic gallbladder carcinoma was found. Further investigations detected no malignancies in other organs. An extended cholecystectomy was performed. Histologic examination of resected specimens revealed poorly differentiated adenocarcinoma with negative resection margins. The eruptions with pruritus resolved within 1 wk after the operation. This is the first report, to our knowledge, of coincident biliary malignancy and erythroderma. The experience of the current patient suggests that erythroderma secondary to GI malignancy may resolve spontaneously after curative resection of the tumor.

    A 72-year-old man was referred to our hospital for suspected gallbladder cancer. We performed cholecystectomy with liver bed resection and lymph node dissection. Intraoperative cytological examination of the bile juice revealed some trophozoites of Giardia lamblia, and pathological examination revealed gallbladder cancer. Therefore, we diagnosed giardiasis associated with gallbladder cancer. We administered 750 mg per day metronidazole for 10 days. The patient was a farmer by occupation and used animal manure for agricultural purposes; he also consumed his own harvest, which was recognized as the infection route for his giardiasis. We reviewed the literature and found very few cases of giardiasis associated with gallbladder cancer.

    BACKGROUND: Incomplete gallbladder removal following open and laparoscopic techniques leads to residual gallbladder stones. The commonest presentation is abdominal pain, dyspepsia and jaundice. We reviewed the literature to report diagnostic modalities, management options and outcomes in patients with residual gallbladder stones after cholecystectomy. MATERIALS AND METHODS: Medline, Google and Cochrane library between 1993 and 2013 were reviewed using search terms residual gallstones, post-cholecystectomy syndrome, retained gallbladder stones, gallbladder remnant, cystic duct remnant and subtotal cholecystectomy. Bibliographical references from selected articles were also analyzed. The parameters that were assessed include demographics, time of detection, clinical presentation, mode of diagnosis, nature of intervention, site of stone, surgical findings, procedure performed, complete stone clearance, sequelae and follow-up. RESULTS: Out of 83 articles that were retrieved between 1993 and 2013, 22 met the inclusion criteria. In most series, primary diagnosis was established by ultrasound/computed tomography scan. Localization of calculi and delineation of biliary tract was performed using magnetic resonance imaging/magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography. In few series, diagnosis was established by endoscopic ultrasound, intraoperative cholangiogram and percutaneous transhepatic cholangiography. Laparoscopic surgery, endoscopic techniques and open surgery were the most common treatment modalities. The most common sites of residual gallstones were gallbladder remnant, cystic duct remnant and common bile duct. CONCLUSION: Residual gallbladder stones following incomplete gallbladder removal is an important sequelae after cholecystectomy. Completion cholecystectomy (open or laparoscopic) is the most common treatment modality reported in the literature for the management of residual gallbladder stones. PMID:26622110

    OBJECTIVE. The purposes of this study were to compare staging accuracy of high-resolution sonography (HRUS) with combined low- and high-MHz transducers with that of conventional sonography for gallbladder cancer and to investigate the differences in the imaging findings of neoplastic and nonneoplastic gallbladder polyps. MATERIALS AND METHODS. Our study included 37 surgically proven gallbladder cancer (T1a = 7, T1b = 2, T2 = 22, T3 = 6), including 15 malignant neoplastic polyps and 73 surgically proven polyps (neoplastic = 31, nonneoplastic = 42) that underwent HRUS and conventional transabdominal sonography. Two radiologists assessed T-category and predefined polyp findings on HRUS and conventional transabdominal sonography. Statistical analyses were performed using chi-square and McNemar tests. RESULTS. The diagnostic accuracy for the T category was T1a = 92-95%, T1b = 89-95%, T2 = 78-86%, and T3 = 84-89%, all with good agreement (κ = 0.642) using HRUS. The diagnostic accuracy for differentiating T1 from T2 or greater than T2 was 92% and 89% on HRUS and 65% and 70% with conventional transabdominal sonography. Statistically common findings for neoplastic polyps included size greater than 1 cm, single lobular surface, vascular core, hypoechoic polyp, and hypoechoic foci (p < 0.05). The value of HRUS in the differential diagnosis of a gallbladder polyp was more clearly depicted internal echo foci than conventional transabdominal sonography (39 vs 21). A polyp size greater than 1 cm was independently associated with a neoplastic polyp (odds ratio = 7.5, p = 0.02). The AUC of a polyp size greater than 1 cm was 0.877. The sensitivity and specificity were 66.67% and 89.13%, respectively. CONCLUSION. HRUS is a simple method that enables accurate T categorization of gallbladder carcinoma. It provides high-resolution images of gallbladder polyps and may have a role in stratifying the risk for malignancy.

    Many studies have reported methods of cell collection involving percutaneous transhepatic cholangiodrainage (PTCD) and fine-needle aspiration cytology for the diagnosis of gallbladder disease. However, few studies have described the use of a transpapillary approach, i.e., endoscopic transpapillary catheterization into the gallbladder (ETCG). In this study, we analyzed cells collected by ETCG to evaluate its usefulness in the cytological diagnosis of gallbladder disease. The subjects were 19 patients who had undergone ETCG for the diagnosis of gallbladder disease. Of these patients, 11 and 8 had gallbladder cancer and benign gallbladder disease, respectively. We also evaluated the diagnostic accuracy of PTCD cytology performed in 15 patients with gallbladder cancer.Specimens were cytologically diagnosed as normal or benign, indeterminate, suspected malignancy, malignant, and inadequate in 47% (9/19), 11% (2/19), 0% (0/19), 37% (7/19), and 5% (1/19) of patients, respectively. Specimens were diagnosed as malignant, indeterminate, normal or benign, and inadequate in 7, 2, 1, and 1, respectively, of the 11 patients diagnosed with gallbladder cancer. The sensitivity and specificity of ETCG cytology were 78 and 100%, respectively, whereas the diagnostic accuracy of PTCD cytology was 20% (3/15). None of the patients developed complications of ETCG. Despite its technical difficulty, ETCG for bile cytology allows the collection of adequate cell numbers from patients with benign disease or gallbladder cancer and facilitates a cytological diagnosis, making it a useful method for collecting cells.

    Noninvasive positive-pressure ventilation (NIPPV) is widely used to treat acute respiratory failure, the goal being to avoid exposing patients to the morbidity associated with tracheal intubation. NIPPV may reduce the rates of intubation, morbidity, and mortality in selected patient subgroups. Although time-consuming for physicians and nurses, NIPPV is fairly easy to use, and few severe complications have been reported. Esophageal perforation is a well-recognized complication of tracheal intubation but has not been described in association with NIPPV. We report a case of fatal esophageal perforation associated with NIPPV after a surgical procedure.

    Spontaneous urinary bladder perforation is a rare event, which requires immediate medical attention due to its extremely high morbidity and mortality. We report a case of a 36-year-old man who presented with acute-onset abdominal pain without any inciting events. His glucose level at the time of presentation was 1107 mg/dL. On initial abdominal imaging, it was believed that he had a large pelvic mass likely originating from the bladder. On further workup at our hospital, it was discovered that he had an intraperitoneal perforation after which he underwent an exploratory laparotomy and a cystorrhaphy. PMID:26955559

    This is a case report of foreign body ingestion in a suicide attempt resulting in gastric perforation and phlegmon formation during a subsequent 6 month period that eventually required surgical intervention. The patient had a prolonged course because she did not report a history of foreign body ingestion and the initial evaluating physicians had no suspicion about possible foreign body ingestion and may have missed important findings on physical examination. Gastric perforation by a foreign object may have a slow course rather than presenting acute abdomen. The realization of a proper physical examination in the emergency department is key to an accurate diagnosis. PMID:26495367

    Gastric perforation secondary to metastasis from breast cancer occurs infrequently. We present the case of a 72-year-old postmenopausal female patient with a known history of lobular carcinoma of the breast who presented to a district general hospital with a clinical diagnosis of an acute abdomen. Further contrast-enhanced CT scan demonstrated free gas and fluid in the abdomen. She underwent emergency exploratory laparotomy and onlay Graham's omentopexy patch due to 1×1 cm prepyloric gastric perforation. Final histopathology proved the presence of metastatic malignant cells in the breast origin. We discuss the issues involved in postoperative investigation and management.

    The egg shell membrane (ESM) patch may promote tympanic membrane (TM) healing in acute traumatic TM perforation. To evaluate the use of ESM for treating acute traumatic TM perforation. We reviewed charts of patients with traumatic TM injury from 2008 to 2011. Treatments were an ESM patch or a perforation edge approximation. We divided patients into two groups according to the treatment used. Each patient was matched by treatment onset and perforation size. We compared healing ratio, healing time, and frequency of otorrhea between the perforation edge approximation group and the ESM patch group. Matched t tests were used for analysis. The healing ratio of the TM showed no significant difference between the two groups, but the time to heal was significantly shorter in the ESM patch group than in the perforation edge approximation group.

    Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01−0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy). Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

    There are currently no reports of the identification of stem cells in the human gallbladder. The differences between human gallbladder and intrahepatic bile duct (IHBD) cells have also not been explored. The goals of this study were to evaluate if human fetal gallbladder contains a candidate stem cell population and if fetal gallbladder cells are distinct from fetal IHBD cells. We found that EpCAM+CD44+CD13+ cells represent the cell population most enriched for clonal self-renewal from primary gallbladder. Primary EpCAM+CD44+CD13+ cells gave rise to EpCAM+CD44+CD13+ and EpCAM+CD44+CD13− cells in vitro, and gallbladder cells expanded in vitro exhibited short-term engraftment in vivo. Last, we found that CD13, CD227, CD66, CD26 and CD49b were differentially expressed between gallbladder and IHBD cells cultured in vitro indicating clear phenotypic differences between the two cell populations. Microarray analyses of expanded cultures confirmed that both cell types have unique transcriptional profiles with predicted functional differences in lipid, carbohydrate, nucleic acid and drug metabolism. In conclusion, we have isolated a distinct clonogenic population of epithelial cells from primary human fetal gallbladder with stem cell characteristics and found it to be unique compared to IHBD cells.

    Gallbladder cancer is the most malign neoplasm of the biliary tract. Chile presents the third highest prevalence of gallbladder cancer in the Americas, being Chilean women from the city of Valdivia the ones with the highest prevalence. The main risk factors associated with gallbladder cancer are: sex, cholelithiasis, obesity, ethnicity, chronic inflammation, history of infection diseases such as Helicobacter pyloriand Salmonellaand family history of gallbladder cancer. In Chile gallbladder cancer mortality is close to prevalence level. This is related to the silent symptomatology of this cancer, as well as the lack of specific symptoms. The high prevalence of obesity and infectious diseases present in Chile are two of the main risk factors of gallbladder cancer and Chile has prevalence of obesity close to 30%. The aim of this literary review is to inform and summarize the main risk factors of gallbladder cancer that are prevalent in Chile, in order to be able to focus preventive and management interventions of this risk factor for the reduction in prevalence and mortality of gallbladder cancer in Chile.

    Global protein analysis of human gallbladder tissue is vital for identification of molecular regulators and effectors of its physiological activity. Here, we employed a genome-wide deep RNA sequencing analysis in 28 human tissues to identify the genes overrepresented in the gallbladder and complemented it with antibody-based immunohistochemistry in 48 human tissues. We characterized human gallbladder proteins and identified 140 gallbladder-specific proteins with an elevated expression in the gallbladder as compared to the other analyzed tissues. Five genes were categorized as enriched, with at least fivefold higher levels in gallbladder, 60 genes were categorized as group enriched with elevated transcript levels in gallbladder shared with at least one other tissue and 75 genes were categorized as enhanced with higher expression than the average expression in other tissues. We explored the localization of the genes within the gallbladder through cell-type specific antibody-based protein profiling and the subcellular localization of the genes through immunofluorescent-based profiling.

    Abstract Background: Reactive perforating collagenosis (RPC) is a rare form of transepithelial elimination, in which altered collagen is extruded through the epidermis. There are 2 types of RPC, acquired RPC (ARPC) and inherited RPC, while the latter is extremely rare. Here we report on 1 case of ARPC. Methods: A 73-year-old female was presented with strongly itchy papules over her back and lower limbs for 3 months. She denied the history of oozing or vesiculation. A cutaneous examination showed diffusely distributed multiple well-defined keratotic papules, 4 to 10 mm in diameter, on the bilateral lower limbs and back as well as a few papules on her chest and forearm. Scratching scars were over the resolved lesions while Koebner phenomenon was negative. The patient had a history of type 2 diabetes for 15 years. Laboratory examinations showed elevated blood glucose level. Skin lesion biopsy showed a well-circumscribed area of necrosis filled with a keratotic plug. Parakeratotic cells and lymphocytic infiltration could be seen in the necrosed area. In dermis, sparse fiber bundles were seen perforating the epidermis. These degenerated fiber bundles were notarized as collagen fiber by elastic fiber stain, suggesting a diagnosis of RPC. Results: Then a diagnosis of ARPC was made according to the onset age and the history of diabetes mellitus. She was treated with topical application of corticosteroids twice a day and oral antihistamine once a day along with compound glycyrrhizin tablets 3 times a day. And the blood glucose was controlled in a satisfying range. Two months later, a significant improvement was seen in this patient. Conclusion: Since there is no efficient therapy to RPC, moreover, ARPC is considered to be associated with some systemic diseases, the management of the coexisting disease is quite crucial. The patient in this case received a substantial improvement due to the control of blood glucose and application of compound glycyrrhizin tablets. PMID

  10. Rett syndrome and gastric perforation.

    Rett Syndrome is associated with decreased peristaltic esophageal waves and gastric dysmotility, resulting in swallowing difficulties and gastric dilation. Rarely, gastric necrosis and perforation occur. Our case represents the third reported case of gastric necrosis and perforation associated with Rett Syndrome. A 31-year-old female after 11 hours of intermittent emesis and constant, sharp abdominal pain presented with evidence of multiorgan system failure including hypovolemic shock, metabolic acidosis, coagulopathy, and hepatorenal failure. A chest radiograph revealed intra-abdominal free air necessitating emergent laparotomy. During exploration, a severely dilated, thin-walled stomach with an area of necrosis and gross perforation was noted. Wedge resection of the necrotic tissue and primary closure were performed. Despite aggressive perioperative resuscitation and ventilation support, the patient died 3 hours postoperatively secondary to refractory shock and hypoxemia. Severe gastric dilation can occur with Rett Syndrome and may cause gastric necrosis and perforation. Prolonged elevated gastric pressures can decrease perfusion and may contribute to perforation. Timely decompression via percutaneous endoscopic or surgical gastrostomy could decrease the risk of perforation particularly when significant gastric distention is present. Consideration of gastric necrosis and perforation in patients with Rett Syndrome may lead to earlier intervention and decreased mortality.

    To determine whether rural patients are more likely to present with perforated appendicitis compared with urban patients. Appendiceal perforation has been associated with increased morbidity, length of hospital stay, and overall health care costs. Recent arguments suggest that high rates of appendiceal rupture may be unrelated to the quality of hospital care, and rather associated with inadequate access to surgical care. We performed a retrospective cohort study of 122,990 patients with acute appendicitis from the Nationwide Inpatient Sample from 2003 to 2004. International Classification of Diseases diagnosis 9 (ICD-9) codes were used to determine appendiceal perforation. Urban influence codes from the US Department of Agriculture were used to determine rural versus urban status. Univariate and multivariate analyses were used to determine patient and hospital factors associated with perforation. Overall, 32.07% of patients presented with perforation. Rural patients were more likely than urban patients to present with perforation (35.76% vs. 31.48%). Factors associated with perforation in multivariate analysis were age more than 40 years, male gender, transfer from another facility, black race, poorest 25th percentile, Charlson score of 3 or higher, and rural residence. Thirty percent of rural patients were treated in urban hospitals. Rural patients treated at urban hospitals were more likely to present with perforation compared with rural patients treated at rural hospitals (OR = 1.23). Patients from rural areas have higher rates of perforation with acute appendicitis than urban patients. This difference persists when accounting for other factors associated with perforation. These differences in perforation rates suggest disparities in access to timely surgical care.

    Xanthogranulomatous cholecystitis is a relatively uncommon variant of chronic cholecystitis, characterized by marked thickening of the gallbladder wall and dense local adhesions. Not only does xanthogranulomatous cholecystitis mimic malignancy, it can also be infrequently associated with gallbladder carcinoma in 0.2% to 35.4% of cases. Herein, the authors report a new case of xanthogranulomatous cholecystitis concomitant with gallbladder adenocarcinoma in a 65-year-old female patient. Because of its overlapping clinical, radiological and macroscopic findings with gallbladder cancer, definitive diagnosis of xanthogranulomatous cholecystitis relies on extensive sampling and thorough microscopic examination of the surgical specimen to exclude the possibility of coexisting tumour. It is still a matter of debate whether xanthogranulomatous cholecystitis is truly a precursor of gallbladder carcinoma or if it is just an incidental finding. This aspect needs to be explored in the future with further studies.

    Adenomyomatosis of the gallbladder is believed to be an uncommon pathologic condition of the gallbladder in childhood. Only three pediatric cases have been described in the literature up to now. Honeycomb gallbladder has been described in two adult patients; no patients have been reported in childhood until now. To the best of our knowledge, we report here the first case of adenomyomatosis of the gallbladder which resembled honeycomb, in a 9-year-old girl presented with recurrent abdominal pain. The diagnosis was made by ultrasound, and confirmed by magnetic resonance cholangiopancreatography and finally cholecystectomy. In conclusion, ultrasound scanning performed more generally in children presenting with recurrent abdominal pain might lead to accurate diagnosis of adenomyomotosis of the gallbladder during childhood.

  14. Role of CEUS in the diagnosis of gallbladder disease.

    2012-12-01

    Conventional ultrasound (US) is the first imaging investigation recommended for diagnosis of gallbladder pathology. However, it has an important limit of ability to depict microcirculation of some biliary lesions which may lead to failure in diagnosis. The use of contrast-enhanced US (CEUS) seems to overcome these limits and allows a more confident diagnosis. In this review, the methodology, image interpretation, enhancement pattern, clinical usefulness, and indications for CEUS in gallbladder lesions are summarized. CEUS may be indicated under the following circumstances: 1) For differentiation diagnosis between a malign tumor or a benign tumor of the gallbladder; 2) to make a distinction between motionless sludge and gallbladder carcinoma; 3) to assess the extension of gallbladder carcinoma in adjacent hepatic parenchyma; 4) patients with impaired renal function.

    Familial adenomatous polyposis is associated with a high incidence of malignancies in the upper gastrointestinal tract (particularly ampullary adenocarcinomas). However, few reports have described a correlation between familial adenomatous polyposis and gallbladder neoplasms. We present a case of a 60-year-old woman with familial adenomatous polyposis who presented with an elevated mass in the neck of the gallbladder (measuring 16 mm × 8 mm in diameter) and multiple small cholecystic polyps. She had undergone a total colectomy for ascending colon cancer associated with familial adenomatous polyposis 22 years previously. The patient underwent laparoscopic cholecystectomy under a preoperative diagnosis of multifocal gallbladder polyps. Pathologic examination of the resected gallbladder revealed more than 70 adenomatous lesions, a feature consistent with adenoma of the gallbladder. This case suggests a requirement for long-term surveillance of the biliary system in addition to the gastrointestinal tract in patients with familial adenomatous polyposis.

    A retroperitoneal perforation is a rare incident. It can occur as a complication of ERCP with papillotomy (0.2-0.5%). Leakage of contrast agent during endoscopy raises the suspicion that this complication has occurred but doesn't always give sufficient information about the leakage extent. In the case of extreme gas emission, a plain abdominal X-ray shows classic pneumoretroperitoneum. The abdominal CT scan can display small amounts of free air which is why it is used for diagnosis in such cases. Ultrasonography also provides a reliable diagnosis and is a good method for monitoring the progression of the condition. Alternative causes of pneumoretroperitoneum can be: trauma, inflammation, infection, tumor as well as ERCP and other interventional procedures, especially endoscopies. Presacral retroperitoneal pneumoradiography was used for the diagnosis of retroperitoneal tumors in the 70 s but is no longer used today. Perforations into the retroperitoneal space come from several locations in the gastrointestinal tract. In the different types of lesions the gas can penetrate the compartments and reach as far as the mediastinum, the intraabdominal cavity, subcutaneum (cervical) or the scrotal compartment (compartment shift). Based on 11 cases (7 perforations during ERCP, 2 perforation during colonoscopy, 2 cases with damage of the distal esophagus), we show the most extensive presentation of the sonographical picture of pneumoretroperitoneum. Typical signs on abdominal ultrasound are an increased echogenicity around the right kidney ("overcasted" or "covered" kidney), air dorsal to the gallbladder, around the duodenum and the head of the pancreas and especially ventral to the great abdominal vessel which can lead to the picture of "vanishing" vessels. The extent of free air is easy to assess. Even very small amounts are detectable ventral to the right kidney. In most cases, a conservative approach with no oral intake, antibiotic coverage, and analgesia in close

    Free perforation in abdominal cavity in patients with Crohn's disease is a rare entity as attested from the data reported in the literature. It is a very dangerous event and requires a surgical urgency management. The Authors reported two cases of free perforation, in patients with Crohn' disease, undergoing surgical operation in urgency. Analyzing pathogenesis, difficulty in diagnosis making and therapeutic choices, they underline that CT is very useful in the diagnosis, while resection of the perforated intestinal tract represent the best surgical treatment.

    Spontaneous, idiopathic urinary bladder rupture is a very rare disease entity, which may face the problem of proper preoperative diagnosis. In many cases the medical history, physical examination, and additional tests raise false suspicion of gastrointestinal perforation. The study presented a case of a female patient with spontaneous urinary bladder perforation, paying particular attention to the diagnostic difficulties associated with the above-mentioned pathology. The aim of the study was to analyse the presence of symptoms and imaging and laboratory results observed in case of spontaneous urinary bladder rupture, as well as differentiate the above-mentioned pathology with gastrointestinal perforation. Whenever diagnosing a patient with acute peritonitis symptoms, in whom the predominating symptoms include sudden abdominal pain, peritoneal cavity fluid presence, hematuria, oliguria, and coexisting increased urea, creatinine, and potassium levels, one should consider the possibility of urinary bladder rupture.

    Activation of TGR5 via bile acids or bile acid analogs leads to the release of glucagon-like peptide-1 (GLP-1) from intestine, increases energy expenditure in brown adipose tissue, and increases gallbladder filling with bile. Here, we present compound 18, a non-bile acid agonist of TGR5 that demonstrates robust GLP-1 secretion in a mouse enteroendocrine cell line yet weak GLP-1 secretion in a human enteroendocrine cell line. Acute administration of compound 18 to mice increased GLP-1 and peptide YY (PYY) secretion, leading to a lowering of the glucose excursion in an oral glucose tolerance test (OGTT), while chronic administration led to weight loss. In addition, compound 18 showed a dose-dependent increase in gallbladder filling. Lastly, compound 18 failed to show similar pharmacological effects on GLP-1, PYY, and gallbladder filling in Tgr5 knockout mice. Together, these results demonstrate that compound 18 is a mouse-selective TGR5 agonist that induces GLP-1 and PYY secretion, and lowers the glucose excursion in an OGTT, but only at doses that simultaneously induce gallbladder filling. Overall, these data highlight the benefits and potential risks of using TGR5 agonists to treat diabetes and metabolic diseases.

    Gallbladder neuroendocrine tumours (GB-NETs) are rare and account for 0.5% of all NETs. GB-NETs have an aggressive behaviour, which depends on the tumour grade. The cytomorphological spectrum of these tumours has never been described in detail. The present study evaluates the cytological features of GB-NETs and grades them according to the World Health Organization (WHO) classification. Furthermore, the expression of thyroid transcription factor-1 (TTF-1) has not been investigated previously in GB-NETs, although found in a subset of extrapulmonary NETs. Twenty cases of GB-NET among 875 gallbladder carcinomas diagnosed by ultrasound-guided fine needle aspiration cytology (FNAC) over a period of nearly 4 years were studied. The following parameters were evaluated: architectural pattern, nuclear chromatin, nucleoli, mitoses, necrosis, moulding, apoptosis and smudge cells. Cases were categorized into well-differentiated (grades 1 and 2), small cell carcinoma (SCC) (grade 3) and mixed adenoneuroendocrine carcinoma. Nuclear positivity for TTF-1 was considered as positive. Morphologically, tumour cells were mainly arranged in rosettes in the well-differentiated category; sudden anisonucleosis and rare nuclear moulding with or without mitotic figures were other features. Eleven cases of SCC showed prominent nuclear moulding with frequent smudge cells, mitoses, apoptosis and necrosis. Three mixed adenoneuroendocrine carcinomas showed papillary fragments and an acinar arrangement of tumour cells. Four of the nine SCCs in which TTF-1 was evaluated on de-stained smears showed nuclear positivity. Histopathology was available in two SCCs and showed morphology similar to FNAC. Cytology plays an important role in the diagnosis of GB-NETs for appropriate subtype characterization, which is necessary for the prognostication of these tumours. TTF-1 may not be used for the differentiation of gallbladder SCCs from pulmonary SCCs. © 2015 John Wiley & Sons Ltd.

    Several studies have suggested an increased prevalence of benign and malignant tumors in acromegaly, particularly colonic neoplasms. The gallbladder's epithelial similarity to the colon raises the possibility that gallbladder polyps (GBP) may occur more frequently in acromegaly. Thirty-one patients with newly diagnosed acromegaly (14 females, 17 males; mean age 54.7 yr, range 27-76 yr) were referred to our center between 2004 and 2008. All had pituitary adenomas and were treated with somatostatin analogs prior to transsphenoidal surgery. Biliary ultrasonography was performed at the time of referral. In a retrospective case-cohort study, we compared the prevalence of GBP in these scans with those of 13,234 consecutive patients (age range 20-80 yr) presenting at the hospital for abdominal/biliary ultrasound during the same time interval. Associations between GH and IGF-I levels and GBP in acromegaly were also examined. There was a higher prevalence of GBP in patients with acromegaly compared with controls (29.03 vs 4.62%, P = 0.000008); relative risk was 6.29 (95% confidence interval 3.61-10.96). Eight of nine patients with acromegaly and GBP were older than 50 yr of age. GH levels were higher in those with GBP (median 30.8 μg/liter, interquartile range 10.9-39.1) than those without (8.2 μg/liter, interquartile range 6.0-16.0), but IGF-I levels were comparable. This is the first study to demonstrate an increased prevalence of GBP in patients with newly diagnosed acromegaly. Further studies are required to determine whether these patients are at increased risk of developing gallbladder carcinoma and to define the role, if any, of biliary ultrasound surveillance.

    We present a case of a 79-year-old immunocompromised female admitted for abdominal pain and sepsis, who had an abdominal computed tomography (CT) showing distal gallbladder fundus wall thickening, pericholecystic edema, and a right posteroinferior hepatic abscess. Subsequent hepatobiliary scintigraphy with Tc-99m diisopropyliminodiacetic acid showed gallbladder filling of the proximal gallbladder fundus, yet no radiotracer filling of the distal gallbladder fundus. Further correlation with the initial CT showed a partial gallbladder stricture and a resultant altered morphology resembling a dumbbell-shaped gallbladder. Percutaneous cholangiogram also confirmed this dumbbell morphology. Nonfilling of radiotracer into the distal end of the dumbbell gallbladder correlating with CT findings of focal gallbladder inflammation indicated that there was a focal inflammation suggesting a distal dumbbell gallbladder cholecystitis. This case demonstrates a unique finding of focal inflammatory pathology involving an anatomic variant - the dumbbell-shaped gallbladder, and the challenges this anatomic variant presents in hepatobiliary scintigraphy image interpretation.

    There is currently no consensus with regard to the use of cholecystectomy or percutaneous cholecystostomy as the therapy of choice for acute acalculous cholecystitis. The goal of this study was to review the scientific evidence on the management of these patients according to clinical and radiographic findings. A systematic review of the literature from 2000 to 2016 was performed. The databases of PubMed, Índice Médico Español, Cochrane Library and Embase were searched according to the following inclusion criteria: publication language (English or Spanish), adult patients, acalculous etiology and appropriate study design. A total of 1,013 articles were identified and ten articles were selected for review. These included five observational controlled studies and five case series which described the outcome of patients treated with percutaneous cholecystostomy and emergency cholecystectomy. No prospective or randomized studies were identified using the search criteria. The data from the literature and analysis of results suggested that percutaneous cholecystostomy may be a definitive therapy for acute acalculous cholecystitis with no need for subsequent elective cholecystectomy. Percutaneous cholecystostomy may be the first treatment option for patients with acute acalculous cholecystitis except in cases with a perforation or gallbladder gangrene. Patients at low surgical risk may benefit from cholecystectomy but both treatment options may be effective. Percutaneous cholecystostomy in patients with acute acalculous cholecystitis may be a definitive therapy with no need for a subsequent elective cholecystectomy. However, the overall quality of studies is low and the final recommendations should be considered with caution.

    There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

    This case describes an intraoperative incidental finding and surgical removal of ectopic liver tissue attached to the gallbladder during a standard laparoscopic cholecystectomy for acute cholecystitis. These anomalies are rare, with interesting associations and possible clinically relevant complications. The details of the case, along with a brief literature review of embryology, common ectopic sites, and associations/complications, are presented in this paper. Since laparoscopic cholecystectomy is a very common procedure, it is important to increase vigilance of ectopic liver tissues during surgeries to minimize complications and provide optimal management.

    During an 11 year period, 47 patients with acute acalculous cholecystitis were operated on. Two to one male/female ratio was observed with a mean age of 55 age of 55 years. No one had a past history of biliary tract pathology but 70 per cent of the patients had risk factors, mainly diabetes mellitus, cardiovascular and collagenous diseases, some different of those reported in the world literature (sepsis, trauma, non biliary tract surgery, etc.). The ultrasound was the best diagnostic tool. Open cholecystectomy was performed in all patients and some sort of local complication was found in 85 per cent of patients (empyema, gangrene or perforation) in spite of the surgical procedure was done on emergency or early elective basis, a 31 per cent operative mortality rate was found and a 10.6% Operative mortality rates was observed. The bacterial cultures showed gram negative and anaerobic flora. This report shows that an early diagnosis and surgical treatment keeps a low morbidity and mortality rates but the gallbladder late complications have a high rates.

    The study aimed at quantitative analysis of expression involving markers of mast cells (tryptase), monocytes/macrophages (CD68 molecule) and dendritic cells (S100 protein) in gallbladder mucosa with acute and chronic calculous cholecystitis. Routinely prepared tissue material from the patients with acute (ACC) (n = 16) and chronic calculous cholecystitis (CCC) (n = 55) was evaluated. Three cellular markers were localized by immunocytochemistry. Their expression was quantified using spatial visualization technique. The expression of tryptase was similar in acute and chronic cholecystitis. CD68 expression in ACC was significantly higher than in the CCC group. Expression of S100 protein was significantly higher in CCC as compared to the ACC group. No significant correlations were disclosed between expression of studied markers and grading in the gallbladder wall. A weak negative correlation was noted between expression of CD68 and number of gallstones in the CCC group. The spatial visualization technique allowed for a credible quantitative evaluation of expression involving markers of mast cells (MCs), monocytes/macrophages (Mo/Ma) and dendritic cells (DCs) in gallbladder mucosa with ACC and CCC. For the first time mucosal expression of S100 protein-positive DCs was evaluated in calculous cholecystitis. The results point to distinct functions of studied cell types in the non-specific immune response in calculous cholecystitis.

    The management of septal perforations is a challenge for the surgeon. A wide variety of surgical techniques have been described, with different approaches. There is no scientific evidence to support a particular approach. The objective of this review is to present a practical guide on the technique of choice for each case of septal perforation. Inspection of the nasal mucosa, the size of the perforation, the location and especially the osteo-cartilaginous support, are the pillars of a successful surgery. For the sliding or rotating flaps of the mucosa of the septum it is essential to know in advance if the elevation of the mucopericondrio or mucoperiosteo of the septum is possible, otherwise the use of these flaps would not be indicated. The flaps of the lateral wall or nasal floor are the alternative. The pericranial flap may be indicated in total or near total perforations. The remnant of the nasal septum and status of osteo-cartilaginous support are the determining factors in the management of septal perforations. Each case should be evaluated individually and the approach chosen according to the size and location of the perforation, mucosal quality, personal history, previous surgery and the experience of the surgeon.

    Stercoral colitis with perforation of the colon is an uncommon, yet life-threatening cause of the acute abdomen. No one defining symptom exists for stercoral colitis; it may present asymptomatically or with vague symptoms. Diagnostic delay may result in perforation of the colon resulting in complications, even death. Moreover, stercoral perforation of the colon can also present with localized left lower quadrant abdominal pain masquerading as diverticulitis. Diverticular diseases and stercoral colitis share similar pathophysiology; furthermore, they may coexist, further complicating the diagnostic dilemma. The ability to decide the cause of perforation in a patient with both stercoral colitis and diverticulosis has not been discussed. We, therefore, report this case of stercoral perforation in a patient with diverticulosis and include a discussion of the epidemiology, clinical presentation, and a review of helpful diagnostic clues for a rapid differentiation to allow for accurate diagnosis and treatment.

    BACKGROUND: Corneal perforation is an uncommon complication associated with keratoconus. The first cases of infectious keratitis and corneal perforation associated with corneal hydrops and contact lens wear are reported in two keratoconus patients. METHODS: A retrospective chart review and histopathological examination were carried out. RESULTS: Both patients progressed to corneal perforation and emergency penetrating keratoplasty. One patient cultured Fusarium and the second patient Serratia marcesens. Both patients wore contact lenses against medical advice. CONCLUSIONS: The tear in Descement's membrane, stromal oedema, and epithelial bedewing associated with corneal hydrops results in loss of the epithelial-endothelial barrier of the cornea, creating a conduit for infectious organisms through the cornea. Acute hydrops associated with epithelial keratitis, stromal swelling, and a Descement's membrane tear may be a significant risk factor for infectious keratitis and corneal perforation. Contact lenses should not be worn during an active corneal hydrops owing to the increased risk for severe infectious keratitis and corneal perforation. Images PMID:8695560

    We present a case of distal large bowel obstruction, in the setting of a competent ileocaecal valve, the caecum is the most common site of perforation (for Laplace's law). We describe a case of obstruction at the rectum due to constricting carcinomatous growth, presenting with perforation of transverse colon (against Laplace's law). A 60-year-old women presented to the emergency department with acute abdominal pain. The pain was preceded by 3 days of intestinal obstruction. Clinically there was guarding and rigidity. Straight X-ray of the abdomen revealed free gas under diaphragm. Surgical exploration revealed transverse colon perforation with carcinoma of rectum. Loop transverse colostomy was performed as the patient was very sick. The patient improved slowly in the intensive care unit. To conclude, even though the caecum is the most common site for perforation in case of distal obstruction, perforation of transverse colon can occur otherwise as a unique presentation.

    Mississippi Foundation for Medical Care (MFMC) conducted a review of gallbladder surgery performed on Mississippi Medicare Patients using hospital claims files and limited record review for verification of claims file data. Significant error rates in the surgeon identification number were found in the claims files. It should also be noted that the current ICD-9-CM coding system does not allow for identification of laparoscopic cholecystectomies converted to open procedures. Past studies have attempted to use claims data alone for these types of analyses. These findings demonstrate the importance of using caution by those attempting to use claims data (without verification) to define patterns of hospital utilization, clinical outcomes and/or physician profiling. Claims data must be tested for validity for reliable pattern analysis. In addition, considerable variation was found among providers in elements such as conversion rates, complication and readmission rates. A few surgeons showed patterns for critical variables that were quite different from the universe. There was however, no statistically significant differences associated between volume of cases performed and outcomes. Time frame comparisons over several years show significant (> 80%) increase in gallbladder surgery since the introduction of the laparoscopic procedure.

    Aquaporins (AQPs) are important in controlling bile formation. However, the exact role in human gallbladder carcinogenesis has not yet been defined. AQP-5-expressing gallbladder carcinoma (GBC) cell lines (NOZ) were transfected with anti-AQP-5 small interfering RNA (siRNA). Growth, migration, invasion assay, and drug susceptibility tests were performed. Next, microRNA (miRNA) expression was analyzed by miRNA oligo chip (3D-Gene®). AQP-5 and AQP-5-related miRNA target gene expressions were also analyzed using tissue microarray (TMA) in 44 GBC samples. Treatment with AQP-5 siRNA decreased cell proliferation, migration, and invasion. On the other hand, those cells increased IC50 of gemcitabine. By performing miRNA assays, miR-29b, -200a, and -21 were shown to be highly overexpressed in cells treated with AQP-5 siRNA NOZ. When focusing on miR-21, phosphatase and tensin homolog (PTEN) was found to be a target of miR-21. In the TMA, AQP-5/PTEN coexpression was significantly associated with the depth of invasion and MIB-1 index (p = 0.003, 0.010). Survival of patients with a high AQP-5/PTEN coexpression was longer than that of patients with a low coexpression (p = 0.003). Our result suggested that miR-21 and PTEN may contribute to the role of AQP-5 in GBC. AQP-5 and PTEN cascades are favorable biomarkers of GBC.

    Nutritional support in critically ill patients is a fundamental principle of patient care. Little is known about gallbladder motility during the interdigestive phase and in response to enteral feeding. The objective of this study was to investigate the effect of enteral feeding on gallbladder function in dogs. The cholagogue meal (Lipofundin infusion) was applied in four anatomical positions (jejunum, duodenojejunal junction, descending duodenum, stomach) in five healthy Beagle dogs. Gallbladder volume (GBV) was monitored by ultrasonography. Lipofundin infusion given through the feeding tube caused a maximal gallbladder contraction of 9.2% (range 3.7-13.9%) in the jejunum, 16.5% (9.1-22.1%) at the duodenojejunal junction and 26.3% (22.8-29.5%) in the descending duodenum. When the cholagogue meal was given through the mouth, it caused a mean 33.8% (28.6-46.5%) maximum gallbladder contraction in the same animals. In conclusion, we can establish that the ultrasound-guided gallbladder emptying method proved to be a useful technique for monitoring the cholagogue effect of Lipofundin meal applied in different anatomical positions of the intestine. The deeper the position of application, the smaller and shorter gallbladder contraction was evoked.

    Background. A left-sided gallbladder is a rare congenital anomaly defined as a gallbladder attached to the lower surface of the left lateral segment of the liver, i.e. to the left of the interlobar fissure and round ligament. Case outlines. In two women aged 42 and 70 years a left-sided gallbladder was associated with a congenital cyst of the liver. In the first patient, the ectopic gallbladder was an incidental finding at operation for a symptomatic liver cyst; as the gallbladder was normal it was not removed. The second patient underwent operation for chronic calculous cholecystitis, when the left-sided gallbladder and congenital liver cyst were found. An operative cholangiogram was normal, the cystic duct joining the common bile duct from the right side. The gallbladder was removed, and the cyst was de-roofed. Both patients had an uneventful recovery and remain symptom-free at 12 and 9 years respectively. Discussion. To the best of our knowledge, the association of these two congenital anomalies has not been described previously. PMID:18333268

    Acute appendicitis is one of the most common causes of acute abdominal pain. Accurate diagnosis is often hindered due to various presentations that differ from the typical signs of appendicitis, especially the position of the appendix. A delay in diagnosis or treatment may result in increased risks of complications, such as perforation, which is associated with increased morbidity and mortality rates. Necrotizing fasciitis caused by perforated appendicitis is extremely rare. We herein report a case of 50-year-old man presenting with an appendiceal abscess in local hospital. After ten days of conservative treatment with intravenous antibiotics, the patient complained about pain and swelling of the right lower limb and computed tomography (CT) demonstrated a perforated appendix and gas and fluid collection extending from his retroperitoneal cavity to the subcutaneous layer of his right loin and right lower limb. He was transferred to our hospital and was diagnosed with necrotizing fasciitis caused by perforated appendicitis. Emergency surgery including surgical debridement and appendectomy was performed. However, the patient died of severe sepsis and multiple organ failure two days after the operation. This case represents an unusual complication of a common disease and we should bear in mind that retroperitoneal inflammation and/or abscesses may cause necrotizing fasciitis through lumbar triangles.

  20. Gallbladder epithelium as a niche for chronic Salmonella carriage.

    2013-08-01

    Although typhoid fever has been intensively studied, chronic typhoid carriage still represents a problem for the transmission and persistence of the disease in areas of endemicity. This chronic state is highly associated with the presence of gallstones in the gallbladder of infected carriers upon which Salmonella can form robust biofilms. However, we hypothesize that in addition to gallstones, the gallbladder epithelium aids in the establishment/maintenance of chronic carriage. In this work, we present evidence of the role of the gallbladder epithelium in chronic carriage by a mechanism involving invasion, intracellular persistence, and biofilm formation. Salmonella was able to adhere to and invade polarized gallbladder epithelial cells apically in the absence and presence of bile in a Salmonella pathogenicity island 1 (SPI-1)-dependent manner. Intracellular replication of Salmonella was also evident at 12 and 24 h postinvasion. A flowthrough system revealed that Salmonella is able to adhere to and form extensive bacterial foci on gallbladder epithelial cells as early as 12 h postinoculation. In vivo experiments using a chronic mouse model of typhoid carriage showed invasion and damage of the gallbladder epithelium and lamina propria up to 2 months after Salmonella infection, with an abundant presence of macrophages, a relative absence of neutrophils, and extrusion of infected epithelial cells. Additionally, microcolonies of Salmonella cells were evident on the surface of the mouse gallbladder epithelia up to 21 days postinfection. These data reveal a second potential mechanism, intracellular persistence and/or bacterial aggregation in/on the gallbladder epithelium with luminal cell extrusion, for Salmonella maintenance in the gallbladder.

    It has been believed that location of the perforation has a significant impact on hearing loss. However, recent studies have demonstrated that the perforation sites had no impact on hearing loss. We measured the velocity and pattern of the manubrium vibration in guinea pigs with intact and perforated eardrum using a laser Doppler vibrometer in order to determine the effects of different location perforations on the middle ear transfer functions. Two bullas from 2 guinea pigs were used to determine stability of the umbo velocities, and 12 bullas from six guinea pigs to determine the effects of different location perforations on sound transmission. The manubrium velocity was measured at three points on the manubrium in the frequencies of 0.5-8 kHz before and after a perforation was made. The sites of perforations were in anterior-inferior (AI) quadrants of left ears and posterior-inferior (PI) quadrants of right ears. The manubrium vibration velocity losses were noticed in the perforated ears only below 1.5 kHz. The maximum velocity loss was about 7 dB at 500 Hz with the PI perforation. No significant difference in the velocity loss was found between AI and PI perforations. The average ratio of short process velocity to the umbo velocity was approximately 0.5 at all frequencies. No significant differences were found before and after perforation at all frequencies (p>0.05) except 7 kHz (p = 0.004) for both AI and PI perforations. The manubrium vibration velocity losses from eardrum perforation were frequency-dependent and the largest losses occur at low frequencies. Manubrium velocity losses caused by small acute inferior perforations in guinea pigs have no significant impact on middle ear sound transmission at any frequency tested. The manubrium vibration axis may be perpendicular to the manubrium below 8 kHz in guinea pigs.

    Lipid histiocytosis of the gallbladder neck lymph node is rarely reported nowadays. Two obese patients presented with gallbladder lithiasis detected on CT scan. The treatment consisted in coelioscopic cholecystectomy. Microscopy revealed subacute/chronic lithiasic cholecystitis and foci of vacuolated cells in the gallbladder neck lymph node. These cells were positive for CD68, CD31, S100 protein, and adipophilin and negative for cytokeratin and Alcian blue. In conclusion, we report lymph node lipid histiocytosis diagnosed microscopically after cholecystectomy. While such lesions may remain unidentified on imaging procedures, the microscopic analysis may require special stains and immunohistochemistry for ruling out adenocarcinoma metastasis.

    Particle induced X-ray emission, particle induced γ-ray emission studies has been carried out to analyse normal and carcinoma tissues and blood samples of gallbladder of both sexes and seventeen trace elements namely Na, Mg, Al, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br and Pb were estimated in the tissue and blood samples. In the present study, concentration of Zn in the carcinoma gallbladder tissue is less than that of the normal gallbladder tissue. Tobacco habit could be one of the important factors to decrease the elemental concentrations in blood and tissue samples.

    Gallstone disease (GSD) is one of the most common biliary tract diseases worldwide in which both genetic and environmental factors have roles in its pathogenesis. Biliary cholesterol supersaturation from metabolic defects in the liver is traditionally seen as the main pathogenic factor. Recently, there have been renewed investigative interests in the downstream events that occur in gallbladder lithogenesis. This article focuses on the role of the gallbladder in the pathogenesis of cholesterol GSD (CGD). Various conditions affecting the crystallization process are discussed, such as gallbladder motility, concentrating function, lipid transport, and an imbalance between pro-nucleating and nucleation inhibiting proteins.

    We present a case of a 59-y-old woman who had undergone cholecystectomy and was subsequently found to have an abscess within the gallbladder fossa. A hepatobiliary scan using (99m)Tc-diisopropyliminodiacetic acid demonstrated the characteristic rim sign, a photopenic defect surrounded by a rim of mildly increased activity immediately adjacent to the gallbladder fossa. The rim sign was thought to be the result of reactive inflammation in the hepatic tissue adjacent to a postoperative abscess within the gallbladder fossa. © 2015 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    Esophageal perforation is a difficult problem in thoracic surgery. Esophageal perforations can be spontaneous, iatrogenic, or malignant. We report two cases of esophageal perforations caused by thoracic osteophytes and different management strategies leading to successful outcomes. An 80-year-old male presented with chest pain and dysphagia following a fall. On endoscopy, an esophageal perforation and foreign body was noted which was confirmed as a thoracic osteophyte on computed tomography scan. He was managed conservatively as he declined surgery. A 63-year-old male was admitted with dysphagia following a food bolus obstruction. Following esophagoscopy and dilatation, there was clinical and radiological evidence of perforation. During surgery, a thoracic osteophyte was identified as the cause of perforation. The perforation was closed in layers and the osteophyte was trimmed. Both patients recovered well. Thoracic osteophytes are a rare cause of esophageal perforations and a high index of suspicion is required in patients with osteoarthritis who present with esophageal perforations.

    The aim of this study is to evaluate the diagnostic value of pre-operative bilirubin levels in the diagnosis of acute appendicitis and appendiceal perforation. A retrospective analysis of 557 patients undergoing emergency appendicectomy over a 24-month period at a large teaching hospital. Hyperbilirubinaemia was defined as >25 µmol/L. Data were analysed using descriptive statistics. 484 of the 557 (86.9 %) operated cases were found histologically to be appendicitis. 116 cases of the 484 were perforated (24 %). Bilirubin levels were significantly higher in the group with appendicitis versus the group found to have a normal appendix at histology, [median (IQR) 12.0 µmol/L (9.00) vs. 8.0 µmol/L (7.00) respectively, p < 0.001], despite being within normal serum bilirubin range. Sensitivity of hyperbilirubinaemia for acute appendicitis was only 8 %, however specificity was 94 %. PPV was 85 % and NPV was 26 %. Whilst bilirubin was higher in patients with a perforated appendix versus acute appendicitis [median (IQR) 13.0 µmol/L (9.00) vs. 11.0 µmol/L (9.00), respectively], statistically, there was no significant difference in pre-operative bilirubin levels between the perforated appendicitis cases and the non-perforated appendicitis cases (p = 0.326). However, the specificity of hyperbilirubinaemia for perforated appendicitis was 93 %, sensitivity 9.4 %, PPV 24 % and NPV 82 %. Bilirubin levels may be high, but remain within normal range, in cases of appendicitis. Therefore, bilirubin levels may be a useful measurement when investigating a patient with suspected appendicitis. Hyperbilirubinaemia is highly specific with regards to perforation, a finding supported by other studies. However, possibly because of the few perforated cases in this study, we cannot recommend that hyperbilirubinaemia be used to predict perforation.

  9. Semianalytical productivity models for perforated completions

    1991-02-01

    This paper discusses the effects of various perforation and reservoir parameters on the productivity (or injectivity) of perforated completions. Because of the complex, 3D flow into a spiral system of perforations, productivity analysis of perforated completion is not easily amenable to analytical treatment. This paper presents a semianalytical solution for the estimation of skin in perforated completions. Results are presented for two separate cases: the 2D-plane-flow problem, which is essentially valid at small dimensionless perforation spacings (large perforation penetrations or high perforation shot densities) and the general 3D problem, where the vertical convergent flow into perforations is significant. In these analyses, the wellbore and vertical-flow effects are quantified in terms of pseudoskins obtained by accurate finite-element simulations. The effects of perforation damage and formation anisotropy are also included. The results provide a better understanding of the relative role of various perforation parameters in affecting well productivity. Because they are based on theoretical considerations, the correlations allow reliable estimates of the skin in perforated completions. New relations are provided for estimating productivity of perforated completions with formation permeability damage. Results indicate the importance of angular phasing, in addition to perforation penetration, in overcoming the effects of formation damage on well productivity.

    Purpose It is increasingly being recognized that the lymph node ratio (LNR) is an important prognostic factor for gallbladder carcinoma patients. The present study evaluated predictors of tumor recurrence and survival in a large, mono-institutional cohort of patients who underwent surgical resection for gallbladder carcinoma, focusing specifically on the prognostic value of lymph node (LN) status and of LNR in stage IIIB patients. Methods Between 2004 and 2011, 123 patients who underwent R0 radical resection for gallbladder carcinoma at the Chonnam National University Hwasun Hospital were reviewed retrospectively. Patients were staged according to the American Joint Committee on Cancer 7th edition, and prognostic factors affecting disease free survival, such as age, sex, comorbidity, body mass index, presence of preoperative symptoms, perioperative blood transfusion, postoperative complications, LN dissection, tumor size, differentiation, lymph-vascular invasion, perineural invasion, T stage, presence of LN involvement, N stage, numbers of positive LNs, LNR and implementation of adjuvant chemotherapy, were statistically analyzed. Results LN status was an important prognostic factor in patients undergoing curative resection for gallbladder carcinoma. The total number of LNs examined was implicated with prognosis, especially in N0 patients. LNR was a powerful predictor of disease free survival even after controlling for competing risk factors, in curative resected gallbladder cancer patients, and especially in stage IIIB patients. Conclusion LNR is confirmed as an independent prognostic factor in curative resected gallbladder cancer patients, especially in stage IIIB gallbladder carcinoma. PMID:23487246

    Gastrointestinal perforations are a complication of 2–10% of duodenal ulcers. There are a variety of etiologies associated with duodenal ulcer formation and its complications. Corticosteroid use is associated with an increased risk of duodenal ulcer perforation, with the first documented case in 1950. Other important medications associated with perforation include NSAIDS and opioids. Beyond medication, one of the most common disease processes, chronic obstructive pulmonary disease (COPD), has been found to be associated with peptic ulcer disease. Up to 30% of COPD patients have been found to have peptic ulcers, and COPD frequency in peptic ulcer disease is 2–3 times the general population. We herein present a case of an acute duodenal ulcer perforation in a patient receiving corticosteroid treatment for an acute COPD exacerbation. PMID:27609727

    The incidence of melanoma has been increasing over the years and it remains, despite the heterogeneous survival for different stages, a disease with high mortality. Dissemination occurs primarily by the lymphatic route, followed by the hematogenous route. Gastrointestinal metastases do occur, but they are mainly intraluminal mucosal melanomas. Peritoneal or primary mucosal melanomas are rare. Only a few cases have been described of patients presenting with acute abdominal pain due to a melanoma. In this report we present a young patient with no prior health problems. Due to silent progression of disease at first, and secondarily avoidance of medical consultation, she finally presented to our emergency department with signs of intestinal perforation. In the operating theater a massive metastasis in the intestines with perforation was seen, as well as many smaller intra-abdominal and cutaneous lesions. Approximately 35 cm of jejunum had to be resected. Furthermore, the primary melanoma on the left forearm was excised and turned out to be in almost complete regression. Although initial recovery after surgery was good, the patient died only one month after presentation due to the advanced nature of her disease, which points to the devastating effect of undiagnosed melanoma and gastrointestinal metastasis. Since the melanoma incidence is rising, similar cases may present in the near future. This emphasizes the importance of proper full physical examination in patients with atypical abdominal symptoms.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

    Freons generally have a low order of toxicity, but exposure to relatively high concentrations (>100 ppm) may produce adverse effects on health. Currently, intoxication reports are unintentional inhalation of CFCs. We report an unintentional ingestion of a mixture of CFCs and the results of a rat study. A 43-year-old man was admitted to the Emergency Department with a chief complaint of acute abdominal pain that developed minutes after he ingested a clear liquid in a water glass, which contained a mixture of Freon and water. Subsequent surgical evaluation revealed perforation of the stomach and necrosis of the stomach wall. He developed a transient rise in his hepatic transaminases, which resolved spontaneously, and fully recovered from his surgery. A murine model of the injury was created to evaluate threshold concentration and effect of time on injury grade. Injury grade increased with delay to histologic analysis from 8 to 24 hours after exposure to Freon. Increasing amounts of Freon also increased the lesion grade score. Patients ingesting Freon need to be closely evaluated for risk of gastric damage and perforation.

    Acute pseudo-obstruction of the colon is a disorder characterised by an increase in intra-luminal pressure that leads to ischaemia and necrosis of the intestinal wall. The mechanism that produces the lesion is unknown, although it has been associated with: trauma, anaesthesia, or drugs that alter the autonomic nervous system. The pathophysiology of medication induced colon toxicity can progress to a perforated colon and potentially death. Present a case of a colonic pseudo-obstruction in a patient with polypharmacy as the only risk factor and to review the medical literature related to the treatment of this pathology. The case is presented of a 67 year old woman with colonic pseudo-obstruction who presented with diffuse abdominal pain and distension. The pain progressed and reached an intensity of 8/10, and was accompanied by fever and tachycardia. There was evidence of free intraperitoneal air in the radiological studies. The only risk factor was the use of multiple drugs. The colonic pseudo-obstruction progressed to intestinal perforation, requiring surgical treatment, which resolved the problem successfully. It is important to consider drug interaction in patients with multiple diseases, as it may develop complications that can be avoided if detected on time.

    The adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) on the gastrointestinal (GI) tract are well known. However, NSAID use rarely leads to a stercoral perforation, an extremely rare but life-threatening cause of acute abdomen. We present a case of stercoral sigmoid colon perforation in a 2-year-old girl, secondary to unintentional NSAID overdose, developing as a result of miscommunication between the general practitioner (GP) and the mother. To the best of our knowledge, stercoral perforation has never before been reported in a child. PMID:24658528

  17. The electrical potential profile of gallbladder epithelium.

    In this study the relative ionic permeabilities of the cell membranes of Necturus gallbladder epithelium have been determined by means of simultaneous measurement of transmural and transmucosal membrane potential differences (PD) and by ionic substitution experiments with sodium, potassium and chloride ions. It is shown that the mucosal membrane is permeable to sodium and to potassium ions. The baso-lateral membrane PD is only sensitive to potassium ions. In both membranes chloride conductance is negligible or absent. The ratio of the resistances of the mucosal and baso-lateral membranes, RM/RS, increases upon reducing the sodium concentration in the mucosal solution. The same ratio decreases when sodium is replaced by potassium which implies a greater potassium than sodium conductance in the mucosal membrane. The relative permeability of the shunt for potassium, sodium and chloride ions is: PK/PNa/PCl=1.81:1.00:0.32. From the results obtained in this study a value for the PK/PNa ratio of the mucosal membrane could be evaluated. This ratio is 2.7. From the same data the magnitude of the electromotive forces generated across the cell membranes could be calculated. The EMF's are -15mV across the mucosal membrane and -81mV across the baso-lateral one. Due to the presence of the low resistance shunt the transmucosal membrane PD is -53.2mV (cell inside negative) and the transmural PD is +2.6mV (serosal side positive). The change in potential profile brought about by the low resistance shunt favors passive entry of Na ions into the cell across the mucosal membrane. Calculations show that this passive Na influx is maximally 64% of the net Na flux estimated from fluid transport measurements. The C-1 conductive of the baso-lateral membrane is too small to allow electrogenic coupling of C1 with Na transport across this membrane. Experiments with rabbit gallbladder epithelium indicate that the membrane properties in this tissue are qualitatively similar to those of Necturus

    Endoscopic closure techniques have been introduced for the repair of duodenal wall perforations that occur during endoscopic retrograde cholangiopancreatography (ERCP). We report a case of successful repair of a large duodenal wall perforation by using double endoscopic band ligation (EBL) and an endoclip. Lateral duodenal wall perforation occurred during ERCP in a 93-year-old woman with acute calculous cholangitis. We switched to a forward endoscope that had a transparent band apparatus. A 2.0-cm oval-shaped perforation was found at the lateral duodenal wall. We repaired the perforation by sequentially performing double EBL and endoclipping. The first EBL was performed at the proximal edge of the perforation orifice, and two-thirds of the perforation were repaired. The second EBL, which also included the contents covered under the first EBL, repaired the defect almost completely. Finally, to account for the possible presence of a residual perforation, an endoclip was applied at the distal end of the perforation. The detection and closure of the perforation were completed within 10 minutes. We suggest that double EBL is an effective method for closure.

    We present 3 consecutive cases of fishbone perforation of the esophagus that resulted in acute mediastinitis. All patients were successfully managed with drainage and debridement of the mediastinum and pleural cavity. However, temporary exclusion with external ligation of the esophagus was also performed in one patient, with spontaneous recanalization two weeks later. We discuss the possible role of this surgical maneuver in the management of esophageal perforation.

    A patient developed acute severe hemodynamic compromise during a transjugular intrahepatic portosystemic shunt (TIPS) procedure for intractable ascites. Rapid clinical and radiographic evaluation of the patient disclosed pericardial blood and cardiac tamponade as the cause, probably due to right heart perforation from guidewire and catheter manipulation. The tamponade was successfully treated percutaneously, and the patient survived. Cardiac tamponade should be considered in the differential diagnosis of patients who develop hypotension during TIPS placement.

    To compare postoperative vaginal incision separation and healing in patients undergoing posterior repair with perforated porcine dermal grafts with those that received grafts without perforations. Secondarily, the tensile properties of the perforated and non-perforated grafts were measured and compared. This was a non-randomized retrospective cohort analysis of women with stage II or greater rectoceles who underwent posterior repair with perforated and non-perforated porcine dermal grafts (Pelvicol(TM) CR Bard Covington, GA USA). The incidence of postoperative vaginal incision separation (dehiscence) was compared. A secondary analysis to assess graft tensile strength, suture pull out strength, and flexibility after perforation was performed using standard test method TM 0133 and ASTM bending and resistance protocols. Seventeen percent of patients (21/127) who received grafts without perforations developed vaginal incision dehiscence compared to 7% (5/71) of patients who received perforated grafts (p = 0.078). Four patients with vaginal incision dehiscence with non-perforated grafts required surgical revision to facilitate healing. Neither tensile strength or suture pull out strength were significantly different between perforated and non-perforated grafts (p = 0.81, p = 0.29, respectively). There was no difference in the flexibility of the two grafts (p = 0.20). Perforated porcine dermal grafts retain their tensile properties and are associated with fewer vaginal incision dehiscences.

    In a population sample of nearly 900 women aged less than 25 years, prevalence of gallbladder stones (GS) was estimated by ultrasound and some risk factors were analyzed. GS were found in 4.8 percent. The prevalence of GS is significantly higher in females with GS in the family history as compared to persons without known GS in the family (11.8 vs. 2.6 percent); in women who have born as compared to nulliparae (10 vs. 3 percent); in obese women (BMI 26 or higher) as compared to lean women (15.1 vs. 4.2 percent). There was no significant correlation between intake of oral contraceptive and prevalence of GS.

    2015-01-01

    Gallbladder cancer (GBC) is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    Background Cholangiocarcinomas (CC) as well as gallbladder cancers are relatively rare and intractable diseases. Clinical, pathological, and epidemiological studies on these tumors have been under investigation. The current status and/or topics on biliary tract cancers have been reported in the East West Association of Liver Tumor (EWALT), held in Milano, Italy in 2015. Summary All the authors, herein, specifcally reported the current status and leading-edge findings on biliary tract cancers as the following sequence: epidemiology of CC, surgical therapy for intrahepatic CC, surgical therapy for perihilar CC, surgical therapy for gallblad der cancer, chemotherapy for biliary tract cancers, and new histological features in CC. Key Message The present review article will update the knowledge on biliary tract cancers, en hancing the quality of daily clinical practice. However, many features about these cancers remain unknown; further studies are required to establish disease-specific optimal treatment strategies. PMID:27995089

    Introduction. Bochdalek hernia is a congenital defect of the diaphragm that is usually diagnosed in the neonatal period and incidentally in asymptomatic adults. Small bowel incarceration in a right-sided Bochdalek hernia is exceptional for an adult. Case Presentation. A 54-year-old woman was admitted for acute dyspnea, tachycardia, hypotension, and fever. Five days before, she had been experiencing an episode of diffuse abdominal pain. The admission chest X-ray was interpreted as right pleural effusion and pneumothorax with left mediastinal shift. Chest tube drainage was purulent. The thoracoabdominal CT examination suspected an intestinal incarceration through a right diaphragmatic defect. At laparotomy, a right-sided Bochdalek hernia was confirmed with a complete necrosis of the incarcerated caecum. Ileocaecal resection was performed, but the patient died from delayed septic complications. Conclusion. Intrathoracic perforation of the caecum is a rare occurrence; delayed diagnosis due to misleading initial symptoms may lead to severe complications and poor prognosis.

    A very rare case of traumatic diaphragmatic hernia is reported in a 65-year-old woman who presented 46 years after her initial thoracoabdominal injury with tension faecopneumothorax caused by a perforated colon in the chest cavity. She presented in a critical condition with severe respiratory distress, sepsis and acute kidney injury. She had a long-standing history of bronchial asthma with respiratory complications and had experienced progressive shortness of breath for the past year. A recent CT scan had excluded the presence of a diaphragmatic hernia but showed a significantly raised left hemidiaphragm. On admission, chest X-rays showed a significantly raised left hemidiaphragm and mediastinal shift, but the possibility of a diaphragmatic hernia with strangulated bowel in the chest was not suspected until the patient was reviewed by the surgical and intensive care unit consultants the next morning and a repeat CT performed. She had a successful outcome after her emergency operation.

    Gallbladder carcinoma is a fatal malignancy of hepatobiliary tract that is generally diagnosed at advanced stages of cancer because of its asymptomatic nature. Advanced GBC tumors are unresectable with poor prognosis. Improvement in GBC patient care requires better understanding of the biological signaling pathways and application of newly discovered drugs for cancer therapy. Herein, we discuss the possibilities and challenges in targeting the hedgehog pathway in gallbladder cancer therapy based on recent developments in the area.

    Gallbladder carcinoma (GBC) is an uncommon malignancy with a high mortality rate. Detecting gallbladder carcinoma in its early stages can be difficult, despite improvements in ultrasound and computed tomography (CT) imaging. Most diagnoses of GBC are made at advanced stages, with the majority being found incidentally during surgery for cholelithiasis. The presented case demonstrates the difficulty of diagnosing GBC preoperatively in its early stages.

    Resveratrol is a polyphenolic compound extracted from plants and is also a constituent of red wine. Resveratrol produces relaxation of vascular smooth muscle and may prevent cardiovascular diseases. Although resveratrol has been reported to cause relaxation of the guinea pig gallbladder, limited data are available about the effect of resveratrol on the gallbladder smooth muscle in humans. The purpose of this study was to investigate the relaxation effects of resveratrol in human gallbladder muscle strips. We studied the relaxant effects of resveratrol in human gallbladder. In addition, we also investigated mechanism of resveratrol-induced relaxation in human gallbladder by tetraethylammonium (a non-selective potassium channels blocker), iberiotoxin (an inhibitor of large conductance calcium-activated potassium channel), glibenclamide (an ATP-sensitive potassium channel blocker), charybdotoxin (an inhibitor of large conductance calcium-activated potassium channels and slowly inactivating voltage-gated potassium channels), apamine (a selective inhibitor of the small conductance calcium-activated potassium channel), KT 5720 (a cAMP-dependent protein kinase A inhibitor), KT 5823 (a cGMP-dependent protein kinase G inhibitor), NG-Nitro-L-arginine (a competitive inhibitor of nitric oxide synthase), tetrodotoxin (a selective neuronal Na(+) channel blocker), and ω-conotoxin GVIA (a selective neuronal Ca(2+) channel blocker). The present study showed that resveratrol has relaxant effects in human gallbladder muscle strips. In addition, we found that resveratrol-induced relaxation in human gallbladder is associated with nitric oxide, ATP-sensitive potassium channel, and large conductance calcium-activated potassium channel pathways. This study provides the first evidence concerning the relaxant effects of resveratrol in human gallbladder muscle strips. Furthermore, these results demonstrate that resveratrol is a potential new drug or health supplement in the treatment of

    Poor prognosis in gallbladder cancer is due to late presentation of the disease, lack of reliable biomarkers for early diagnosis and limited targeted therapies. Early diagnostic markers and novel therapeutic targets can significantly improve clinical management of gallbladder cancer. Proteomic analysis of four gallbladder cancer cell lines based on the invasive property (non-invasive to highly invasive) was carried out using the isobaric tags for relative and absolute quantitation labeling-based quantitative proteomic approach. The expression of macrophage migration inhibitory factor was analysed in gallbladder adenocarcinoma tissues using immunohistochemistry. In vitro cellular assays were carried out in a panel of gallbladder cancer cell lines using MIF inhibitors, ISO-1 and 4-IPP or its specific siRNA. The quantitative proteomic experiment led to the identification of 3,653 proteins, among which 654 were found to be overexpressed and 387 were downregulated in the invasive cell lines (OCUG-1, NOZ and GB-d1) compared to the non-invasive cell line, TGBC24TKB. Among these, macrophage migration inhibitory factor (MIF) was observed to be highly overexpressed in two of the invasive cell lines. MIF is a pleiotropic proinflammatory cytokine that plays a causative role in multiple diseases, including cancer. MIF has been reported to play a central role in tumor cell proliferation and invasion in several cancers. Immunohistochemical labeling of tumor tissue microarrays for MIF expression revealed that it was overexpressed in 21 of 29 gallbladder adenocarcinoma cases. Silencing/inhibition of MIF using siRNA and/or MIF antagonists resulted in a significant decrease in cell viability, colony forming ability and invasive property of the gallbladder cancer cells. Our findings support the role of MIF in tumor aggressiveness and suggest its potential application as a therapeutic target for gallbladder cancer.

    Objective: To study the clinicopathologic features of invasive micropapillary carcinoma (IMPC) of the gallbladder. Methods: Among 160 resected cases of gallbladder adenocarcinomas, the clinical and histological features of gallbladder adenocarcinomas with invasive micropapillary components (IMPC≥5%) were studied. Results: The detection rate of IPMC among gallbladder adenocarcinomas was 19.4% (31/160). Among these 31 cases, the patients' age ranged from 42 to 84 years (mean 64.8 years). The male-to-female ratio was 1∶4.Histologically, 19 cases were characterized by small papillary tufts lacking central fibrovascular cores, lying freely within the clefts of fibrous tissue, resembling IMPC of the breast; in five cases, the micropapillary tufts floated within cystic spaces lined by tumor cells, resembling IMPC of the lung; in four cases, slender, delicate filiform processes on the tumor surface with classic IMPC in the depth of gallbladder was observed; and in three cases mixed features were seen. Small cluster invasion (SCI) was seen adjacent to the IMPC. The lymph node metastatic rate, the lymphovascular invasion rate, and the SCI detection rate were significantly higher in the IMPC group (P=0.000). The IMPC detection rate was related to poorer histological differentiation and increased T stage (P=0.012, C=0.67; P=0.011, C=0.68). The two-year survival rate of IMPC (4/18) was significantly lower than usual gallbladder carcinoma (54.8%, 23/42). Conclusions: Compared to conventional adenocarcinoma of the gallbladder, IMPC has a more advanced tumor status and is prone to lymphovascular invasion and lymph node metastasis, which thus leads to short-term survival. Moreover, SCI may play an important role in the invasion of the IMPC of the gallbladder.

    To assess the role of nicotine in gallbladder carcinoma and its association with the stage and degree of cancer differentiation. Tissue samples from gallbladder were obtained from 20 patients with gallbladder cancer and 20 age- and gender-matched patients with cholelithiasis who served as the control group. Gallbladder tissue (2 g) was extracted and analyzed for nicotine content using capillary gas chromatography. Nitrogen was used as the carrier gas. Standard curves of nicotine in methanol were made by injecting the internal standards. A significantly higher tissue nicotine concentration was observed in the gallbladder carcinoma group than that in the control group (179.63 ng/mg vs 6.00 ng/mg, P < 0.001). The stage and degree of cancer differentiation did not seem to affect the nicotine levels. Gallbladder tissue contained a significantly higher nicotine concentration in smokers with cancer compared with those in the control group (1570.00 ng/mg vs 232.25 ng/mg, P < 0.001). Interestingly, non-smokers in cancer group also had a higher nicotine concentration than the control group (161.50 ng/mg vs 4.00 ng/mg, P = 0.002). Nicotine is selectively concentrated in malignant gallbladder tissue irrespective of smoking status, showing its strong association with gallbladder cancer. © 2012 The Authors.

    The use of laparoscopy has been established in improving perioperative and postoperative outcomes for patients with simple appendicitis. Laparoscopic appendectomy is associated with less wound pain, less wound infection, a shorter hospital stay, and faster overall recovery when compared to the open appendectomy for uncomplicated cases. In the past two decades, the use of laparoscopy for the treatment of perforated appendicitis to take the advantages of minimally invasiveness has increased. This article reviewed the prevalence, approaches, safety disclaimers, perioperative and postoperative outcomes of the laparoscopic appendectomy in the treatment of patients with perforated appendicitis. Special issues including the conversion, interval appendectomy, laparoscopic approach for elderly or obese patient are also discussed to define the role of laparoscopic treatment for patients with perforated appendicitis.

    We describe here an interstitial Cajal-like cell type (ICLC) in human gallbladder, resembling the archetypal enteric interstitial cells of Cajal. Gallbladder ICLC were demonstrated in fresh preparations (tissue cryosections) using methylene-blue, and fixed specimens in Epon semi-thin sections stained with toluidine blue or transmission electron microscopy (TEM). The positive diagnosis of gallbladder ICLC was further verified by immunohistochemistry: CD117/c-kit, CD34, and another 16 antigens: vimentin, desmin, nestin, alpha-smooth muscle actin, NK-1, S-100, PGP-9.5, tau protein, chromogranin A, NSE, GFAP, CD1a, CD62-P, CD68, estrogen and progesterone receptors. Double immunostaining was performed for CD117, CD34 and CD117 and nestin, respectively. In fresh specimens, the spatial density of gallbladder ICLC was 100-110 cells/mm(2). ICLC mainly appeared beneath the epithelium and in muscularis (about 7%, and approximately 5%, respectively). In toto, ICLC represent in gallbladder approximately 5.5% of subepithelial cells. TEM showed that diagnostic criteria were fulfilled by ICLC. Moreover, TEM indicated that the main ultrastructural distinctive feature for ICLC, the cell processes, develop into the characteristic shape at a relatively early stage of development. It remains to be established if, in humans, ICLC are involved in gallbladder (dis)functions (e.g. pace-making, secretion (auto-, juxta- and/or paracrine), intercellular signaling, or stone formation).

    INTRODUCTION Reports of a giant gallbladder are rare. PRESENTATION OF CASE A 77-year-old woman was admitted with complaints of dull pain in the right half of the abdomen and a palpable mass at the same place. A computerized tomography scan revealed an extremely enlarged gallbladder. Open cholecystectomy was performed. The volume of the removed organ was as much as 3.35 L. Follow-up after 18 months showed that the patient was well. Examination revealed no significant acquired or congenital anomalies that might explain the excessive enlargement of the gallbladder. DISCUSSION We define a ‘giant’ gallbladder as an extreme enlargement of the organ with a volume exceeding 1.5 L, so that its weight is comparable to or even exceeds the mean (estimated) weight of the adult liver (1.5 kg). The first clinical presentation of such an enlargement is likely to differ from any other gallbladder disease, but rather to resemble a tumour or cyst of the abdominal cavity. CONCLUSION A giant gallbladder is a special clinical and pathological entity in surgical practice, of unknown origin. It may develop in patients of any age, and mimics a large abdominal tumour or peritoneal cyst. Both the diagnostic process and surgical treatment demand non-routine approaches. Early and late follow-up results seem to be favourable. PMID:25194602

    Altered gallbladder motility could predispose to, or result from, gallstone formation and could also explain the alleged relief of biliary colic seen during bile acid therapy. Therefore, in 14 controls, 25 patients with radiolucent gallstones, and 14 patients with radiopaque gallstones, the authors used two techniques to measure gallbladder contraction--radionuclide imaging and real-time ultrasound--in response to one of two stimuli--a Lundh meal or intravenous cholecystokinin-octapeptide. Using the radionuclide technique, postprandial gallbladder emptying (t1/2) was prolonged both in patients with radiopaque and radiolucent gallstones when compared with controls. In patients with radiolucent stones, the t1/2 of gallbladder emptying became further prolonged after 1 mo of therapy with ursodeoxycholic acid. A similar pattern of results was seen after cholecystokinin-octapeptide and also with real-time ultrasound. Thus, after both stimuli and using two independent techniques, gallbladder contraction was reduced in patients with gallstones. The slower and less complete gallbladder emptying with ursotherapy might explain the reduction in biliary colic noted during treatment.

    Gallbladder cancer, although regarded as the most common malignancy of the biliary tract, continues to be associated with a dismal overall survival even in the present day. While complete surgical removal of the tumour offers a good chance of cure, only a fraction of the patients are amenable to curative surgery owing to their delayed presentation. Moreover, the current contribution of adjuvant therapies towards prolonging survival is marginal, at best. Thus, understanding the biology of the disease will not only enable a better appreciation of the pathways of progression but also facilitate the development of an accurate genetic model for gallbladder carcinogenesis and dissemination. This review provides an updated, evidence-based model of the pathways of carcinogenesis in gallbladder cancer and its dissemination. The model proposed could serve as the scaffolding for elucidation of the molecular mechanisms involved in gallbladder carcinogenesis. A better understanding of the pathways involved in gallbladder tumorigenesis will serve to identify patients at risk for the cancer (and who thus could be offered prophylactic cholecystectomy) as well as aid oncologists in planning the most suitable treatment for a particular patient, thereby setting us on the vanguard of transforming the current treatment paradigm for gallbladder cancer.

    This paper presents an approach to gallbladder shape comparison by using 3D shape modeling and decomposition. The gallbladder models can be used for shape anomaly analysis and model comparison and selection in image guided robotic surgical training, especially for laparoscopic cholecystectomy simulation. The 3D shape of a gallbladder is first represented as a surface model, reconstructed from the contours segmented in CT data by a scheme of propagation based voxel learning and classification. To better extract the shape feature, the surface mesh is further down-sampled by a decimation filter and smoothed by a Taubin algorithm, followed by applying an advancing front algorithm to further enhance the regularity of the mesh. Multi-scale curvatures are then computed on the regularized mesh for the robust saliency landmark localization on the surface. The shape decomposition is proposed based on the saliency landmarks and the concavity, measured by the distance from the surface point to the convex hull. With a given tolerance the 3D shape can be decomposed and represented as 3D ellipsoids, which reveal the shape topology and anomaly of a gallbladder. The features based on the decomposed shape model are proposed for gallbladder shape comparison, which can be used for new model selection. We have collected 19 sets of abdominal CT scan data with gallbladders, some shown in normal shape and some in abnormal shapes. The experiments have shown that the decomposed shapes reveal important topology features.

    Despite being a classic target for the gastrointestinal peptide hormone, cholecystokinin (CCK), the gallbladder CCK receptor is not well characterized. Pharmacological studies of small species suggest that CCK action can be mediated by direct myogenic or by both myogenic and neurogenic receptors. To prepare for the biochemical characterization of a gallbladder CCK receptor and to define the subtype of the receptor being studied. The authors have performed autoradiographic localization and pharmacological characterization of CCK receptors on bovine gallbladder. Autoradiography demonstrated high-affinity specific CCK-binding sites only on the muscularis. CCK-8 stimulated tonic contraction of longitudinal strips of gallbladder muscularis in a concentration-dependent manner. Antagonism at the cholinergic receptor with 1{mu}M atropine or axonal transmission with 1{mu}M tetrodotoxin did not modify CCK-induced contraction, supporting a direct myogenic effect of this hormone. Optimal electrical field stimulation to elicit a neuronal response resulted in muscle strip relaxation, which was abolished with adrenergic blockade. Although acetylcholine administration stimulated contraction, electrical field stimulation did not, even in the presence of phentolamine, propranolol, and/or CCK. Thus, in bovine gallbladder muscularis, there is evidence for a functional CCK receptor only on smooth muscle cells. Demonstration of a single, high-affinity specific CCK-binding site on an enriched plasma membrane preparation of bovine gallbladder muscularis is consistent with this representing a myogenic CCK receptor.

    Gallbladder cancer is the most common biliary tract cancer and the fifth most common cancer of the digestive system. However, the clinicopathologic features of gallbladder cancer in young Korean patients have not been studied. This study included 101 consecutive cases of gallbladder cancer that underwent cholecystectomy at Kangbuk Samsung Hospital from December 1990 to March 2011. The patients were divided into two groups by age at initial diagnosis of gallbladder cancer: a young patient group aged less than 45 years and an old patient group aged 45 or older. The young patient group included 10 patients with mean age of 38 (range, 29-44 years). Compared with the old patient group, the young patient group showed polypoid tumor appearance (p=0.014), lower pT stage (p=0.023), more frequent adenoma background (p=0.009), and less frequent dysplasia in remaining mucosa (p=0.001). The disease-related survival rate after 13.5 months was significantly more favorable for the young patients. Gallbladder cancers in young Korean patients have distinct clinicopathologic features of a high frequency of cancer arising in adenoma, rare association with intestinal metaplasia and dysplasia, and a favorable patient's prognosis. These findings suggest that the adenoma-carcinoma pathway could contribute more to gallbladder cancer carcinogenesis in young Korean patients than the metaplasia-dysplasia-carcinoma pathway.

    Patients with advanced or metastatic cancer have compromised nutritional, metabolic, and immune conditions. Nevertheless, little is known about gastroduodenal perforation in cancer patients. Described in the present report is the case of a 41-year old woman with stage IV recurrent laryngeal cancer, who used homeopathic anticancer therapy and who had triple peptic ulcer perforation (PUP) that required surgical repair. Triple gastric PUP is a rare complication. Self-administration of homeopathic anticancer medication should be strongly discouraged when evidence-based data regarding efficacy and toxicity is lacking.

    To provide a comprehensive review for development and existing problems of the perforator flaps. The related home and abroad literature concerning perforator flaps was extensively reviewed. The perforator flaps are defined as the axial flaps nourished solely by small cutaneous perforating vessels (perforating arteries and veins), which are exclusively composed of skin and subcutaneous fat. The perforator flaps have the advantages as follows: less injury at donor site, less damage to the contour of the donor site, good reconstruction and appearance of the recipient site flexible design, and short time of postoperative recovery, which have been widely used in reconstructive surgery. The perforator flaps are the new development of the microsurgery, which usher an era of small axial flaps; However, the controversies of the definition, vascular classification, the nomenclature, and the clinical application of the perforator flaps still exist, which are therefore the hot spot for future study.

    The inactivation of the tumor suppressor gene and activation of the proto-oncogene are key steps in the development of human cancer. p53 and beta-catenin are examples of such genes, respectively. In the present study, our aim was to determine the role of these genes in the carcinogenesis of the gallbladder by immunohistochemistry. Sections from paraffin-embedded blocks of surgically resected specimens of gallbladder cancer (GBC) (80 cases), chronic cholecystitis (60 cases), and control gallbladders (10 cases) were stained with the monoclonal antibody p53, and polyclonal antibody beta-catenin. Results were scored semiquantitatively and statistical analysis performed. p53 expression was scored as percentage of the nuclei stained. Beta-catenin expression was scored as type of expression-membranous, cytoplasmic, and nuclear staining. Beta-catenin expression was correlated with tumor invasiveness, differentiation, and stage. Over-expression of p53 was seen in 56.25% of GBC cases and was not seen in chronic cholecystitis or in control gallbladders. p53 expression in gallbladder cancer was significantly higher than in inflammatory or control gallbladders (P < 0.0001). p53 expression increased with increasing tumor grade (P = 0.039). Beta-catenin nuclear expression was seen in 75% cases of gallbladder cancer and in no case of chronic cholecystitis and control gallbladder. Beta-catenin nuclear expression increased with tumor depth invasiveness, and grade (P = 0.028 and P = 0.0152, respectively). p53 and beta-catenin nuclear expression is significantly higher in GBC. p53 expression correlates with increasing tumor grade while beta-catenin nuclear expression correlates with tumor grade and depth of invasion, thus suggesting a role for these genes in tumor progression of GBC.

    Five cases of primary carcinoma of the gallbladder are presented. The cases were identified after a study of 802 cholecystectomies in a period of 5 years. The patients are three women and two men between the ages of 43 and 60 years (mean, 55.8 years). In three cases the clinical diagnosis was that of carcinoma, while in two other patients the clinical diagnosis was that of acute cholecystitis. Grossly, all cases were characterized by a gray-white diffuse or focal plaque-like thickening of the gallbladder wall, with loss of the normal velvety mucosal surface and fibrosis of the organ. Histologically, four cases belong to moderately to poorly differentiated adenocarcinoma and were characterized by infiltrative, irregularly shaped and sized glands, islands, nests, and cords. The cells showed pleomorphic nuclei with clumped chromatin and frequent single nucleoli. One case was a mucinous adenocarcinoma characterized by large pools of mucoid material with neoplastic glands and cells "floating" within. Pathologic staging was pT3 in three cases; pT2 in one case; and pT2N1 in one other case. The present study highlights the importance of careful gross and histopathologic evaluation of gallbladders otherwise removed with the history of chronic or acute cholecystitis. In addition, it highlights the incidence of gallbladder carcinoma in a particular institution.

    The authors present case of patient with biliary stent dislocation after chest injury and fracture of VIII. rib. Polymorbid patient with cirrhosis, chronic pancreatitis, portal hypertension (Child Plugh B) and biliary stent insertion came with acute abdominal pain and inflammatory signs. Progressive signs of acute abdomen have led to laparotomy. Perforation of duodeno-jejunal-loop due to dislocated biliary stent, small loop adhesions and thickened intestine wall were found. Postsurgical period was complicated with obstructive ileus, cholecystitis and cholangiolitis and the second biliary stent was inserted. Present-day status of the patient is satisfactory.

    Introduction. Gallstone ileus (GSI) of the colon is an extremely rare entity with potentially serious complications including perforation. Case Presentation. An 88-year-old man presented to the emergency department with abdominal pain and distension. Clinical exam revealed signs of peritonism. Computed tomography (CT) revealed GSI of the transverse colon with a closed-loop large bowel obstruction (LBO) and caecal perforation. The patient underwent emergency laparotomy. A right hemicolectomy was performed, the gallstone was removed, and a primary bowel anastomosis was undertaken. A Foley catheter was sutured into the residual gallbladder bed to create a controlled biliary fistula. The patient recovered well postoperatively with no complications. He was discharged home with the Foley catheter in situ. Discussion. Gallstone ileus is a difficult diagnosis both clinically and radiologically with only 50% of cases being diagnosed preoperatively. Most commonly it is associated with impaction at the ileocaecal valve and small bowel obstruction. Gallstone ileus should also be considered as a rare but potential cause of LBO. This is the first reported case of caecal perforation secondary to gallstone ileus of the transverse colon. Successful operative management consisted of a one-stage procedure with right hemicolectomy and formation of a controlled biliary fistula.

    To improve the rate of detection of Clonorchis sinensis infection, we compared different specimens from patients with cholecystolithiasis. Feces, gallbladder bile, and gallbladder stones collected from 179 consecutive patients with cholecystolithiasis underwent microscopic examination, and according to the results, 30 egg-positive and 30 egg-negative fecal, gallbladder bile, and gallbladder stone specimens, respectively, underwent real-time fluorescent PCR. The detection rates of eggs in feces, bile, and gallbladder stones were 30.7%, 44.7%, and 69.8%, respectively, and the differences were statistically significant (P<0.01). The PCR results confirmed that the eggs in the specimens were C. sinensis eggs. Eggs in the feces were "fresh" and in the gallbladder stones were "old." Microscopic examination of gallbladder stones may improve the detection rates of C. sinensis infection, which is important for developing individualized treatments to prevent the recurrence of gallbladder stones and to prevent the occurrence of severe liver damage and cholangiocarcinoma.

    Endoscopic ultrasound (EUS) has recently played an increasing role in the diagnosis of gallbladder diseases. This review aims to summarize the role of EUS in the diagnosis of gallbladder lesions. EUS provides high-resolution images that can improve the diagnosis of gallbladder polypoid lesions and microlithiasis, in addition to evaluating gallbladder thickness and staging of gallbladder carcinoma. Contrast-enhancing agents may be useful for the differential diagnosis of gallbladder lesions, but the evidence of their effectiveness is still limited and further studies are required in this area to establish its usefulness. Endoscopic ultrasound combined with fine needle aspiration has played an increasing role in providing histological diagnosis of gallbladder tumors in addition to gallbladder thickening.

    Gallbladder cancer is an uncommon but lethal malignancy with particularly high incidence in Chile, India, Japan and China. There is a paucity of unbiased large-scale studies investigating molecular basis of gallbladder cancer. To systematically identify differentially regulated proteins in gallbladder cancer, iTRAQ-based quantitative proteomics of gallbladder cancer was carried out using Fourier transform high resolution mass spectrometry. Of the 2575 proteins identified, proteins upregulated in gallbladder cancer included several lysosomal proteins such as prosaposin, cathepsin Z and cathepsin H. Downregulated proteins included serine protease HTRA1 and transgelin, which have been reported to be downregulated in several other cancers. Novel biomarker candidates including prosaposin and transgelin were validated to be upregulated and downregulated, respectively, in gallbladder cancer using tissue microarrays. Our study provides the first large scale proteomic characterization of gallbladder cancer which will serve as a resource for future discovery of biomarkers for gallbladder cancer. PMID:24657443

    Intestinal perforation due to foreign body (FB) ingestion is rare (1%). We describe our experience in treating these lesions surgically. From 1995 to 2006, data were collected prospectively in 33 patients (18 women and 15 men; mean age 64 years) operated on for intestinal perforation due to an ingested FB. The type of object, preoperative diagnosis, perforation site, treatment, morbidity and mortality were reviewed. Foreign body ingestion was predominantly involuntary (88%). The mean time from ingestion to perforation was 10.4 days. The most frequently ingested objects were dietary FB (n = 21) and toothpicks (n = 6). The most frequent predisposing factors were dentures or an orthodontic appliance (73%). The most common preoperative diagnoses were acute abdomen of uncertain origin (n = 7), acute appendicitis (n = 7) and acute diverticulitis (n = 5). Pneumoperitoneum was observed in 10 cases. The diagnosis was reached during laparotomy in 30 (91%) cases. The most frequent perforation site was the colorectal region (n = 18, 54.5%), followed by the terminal ileum (n = 7, 21.2%); intraperitoneal perforation was the most common (n = 30, 91%). All cases had abdominal contamination and 22 (66.7%) had diffuse peritonitis. Treatment was always by surgery and antibiotics. Thirteen patients required a colostomy. Morbidity was 57.6% (n = 19) and mortality 6.1% (n = 2). Intestinal perforation by a foreign body is rare and normally affects the sigmoid colon, rectum or distal ileum. Dentures are a common risk factor. Patients are rarely aware of foreign body ingestion. Dietary FB and toothpicks are the most commonly ingested objects. Treatment consists of surgery and antibiotics. Appendicitis and acute diverticulitis should be considered in the differential diagnosis.

    Ultrasonography was performed as the first imaging procedure in 100 patients who presented with acute right upper quadrant pain suggestive of cholecystitis or cholelithiasis. In the final analysis 46 patients were found to have gallbladder disease (40 patients with cholelithiasis, 5 with acalculous cholecystitis, and 1 with a cholesterol polyp in the gallbladder). In 22 of 54 patients with a normal gallbladder, other abdominal disease was found. The error rate for ultrasound was 5%, and in 4 patients ultrasound was not the suitable procedure for the diagnosis. In 91 patients the ultrasonographic diagnosis was correct.

    Perforation is an artificial communication between the root canal system and supporting tissues of the teeth. Root perforation complicates the treatment and deprives the prognosis if not properly managed. A wide variety of materials to seal the perforations have been suggested in literature. There are many comparative studies showing the efficacy of one material over the other. Literature shows many reviews on diagnosis, treatment plan and factors affecting prognosis of perforation repair; but none of these articles elaborated upon various materials available to seal the perforation. The present article aims at describing all the materials used for perforation repair from the past till date; it also offers a literature review of all the articles published over last four decades referred to the treatment of perforation with various root repair materials.

    Multiple magnet ingestion during childhood may result in emergency situations. A single magnet may be discharged with intestinal peristalsis, but multiple magnets may stick together and cause significant intestinal complications. Here we present a case with intestinal perforation due to ingestion of multiple magnets and metal pieces. An eight-year-old girl presented with abdominal pain and vomiting. She had abdominal tenderness and defense on the physical examination. Abdominal X-ray showed air and fluid levels. Metallic images were not considered at first as important in the diagnosis. Abdominal ultrasonography was reported as acute appendicitis. During the abdominal exploration, the appendix was normal, but there were dense adherences around the ileum and cecum. After adhesiolysis, intestinal perforations were seen in the cecum and 15 and 45 cm proximal to the cecum. Magnet and metal pieces were present in the perforated segments. Wedge resection and primary repair was performed. There were no postoperative complications, and she was discharged on the postoperative fifth day. Pediatric surgeons should be aware of the complications of multiple magnet ingestion. If the patient has a history of multiple magnet ingestion, follow-up with daily abdominal X-rays should be done, and in cases where magnets seem to cluster together or if acute abdominal signs develop, surgical exploration should be considered.

    To examine whether density of providers or health care facility factors have a significant effect on the rates of perforated appendicitis in the pediatric population. A retrospective database analysis. Data were linked to the Area Resource File to determine if there was an association between perforated appendicitis and density of provider and facility factors. The National Inpatient Sample database and the Kids' Inpatient Database from 1988 to 2005. All patients included had an age at admission of younger than 18 years and were selected by International Classification of Diseases, Ninth Revision code as having perforated appendicitis (540.0 or 540.1) or acute appendicitis (540.9). Main Outcome Measure Odds ratio of perforated appendicitis to acute appendicitis by county-level density of provider and health care facility factors. The odds ratio of perforated appendicitis to acute appendicitis when stratified by quartiles of increasing density of providers and facility-level factors was statistically significant only for the highest-density quartile of pediatricians (odds ratio = 0.88; 95% confidence interval = 0.78-0.99). Increasing geographic density of pediatricians was associated with a decreasing trend in the odds ratio of perforated appendicitis, with a statistically significant protective effect observed in the highest-density quartile of pediatricians. The density of all other provider and health care facility factors analyzed did not demonstrate a significant association with the rates of perforated appendicitis.

    The aim of this study is to determine the effectiveness and biocompatibility of polypropylene mesh for the repair of nasal septal perforations in an animal model on rabbits. A full-thickness nasal septal perforation with a diameter of nearly 10 × 10 mm was created on 12 rabbits, and then the perforation was reconstructed with two different methods. We used mucosal flaps and polypropylene mesh as an interpositional graft in group 1. Only mucosal flaps were used for reconstruction and are identified as group 2. After 4 weeks, we removed the nasal septum of the rabbits and performed histopathological examinations for acute rejection, infection, inflammatory response, fibrosis, and granuloma formation. We found perforation closure rates of 75 and 25 % in groups 1 and 2, respectively. Inflammatory response was seen in all specimens of group 1 (100 %). The inflammatory response was +1 in five of the specimens (62.5 %), +2 in one specimen (12.5 %), and +3 in two specimens (25 %). Mild fibrosis around the mesh was detected in four specimens (50 %), medium-level fibrosis was detected in one (12.5 %), and no fibrosis was detected in three (37.5 %). Severe fibrosis was not seen in any specimens. The foreign-body reaction was limited to a few giant cells, and granuloma formation was seen in two specimens (25 %). The propylene mesh showed excellent biocompatibility with the septal mucosa, and it can, therefore, be used for the repair of septal perforation as an interpositional graft safely.

    The co-existence of acquired immune deficiency syndrome (AIDS) and tuberculosis is a major cause of morbidity and mortality because of a widespread organ involvement. The gastrointestinal tract is a common site for localization of opportunistic microorganisms in AIDS. However, surgical abdominal emergencies such as intestinal perforation resulted from tuberculosis are uncommon in these patients. The asymptomatic occurrence of such intestinal perforation has not been reported our knowledge. We represent an HIV and HCV co-infected man with miliary tuberculosis and an incidentally detected free air under  diaphragm in the chest X-ray eventually resulting in exploratory laparotomy which then revealed two tubercular-induced intestinal perforations. It seems that as the tuberculosis is increasing in incidence, mostly due to reactivation in HIV-infected patients especially in developing countries, we should not underestimate its acute abdominal emergencies such as bowel perforation.

  6. Gallstone disease: Epidemiology of gallbladder stone disease.

    Gallstone disease is common: >700,000 cholecystectomies and costs of approximately 6.5 billion dollars annually in the U.S. The burden of disease is epidemic in American Indians (60-70%); a corresponding decrease occurs in Hispanics of mixed Indian origin. Ten to fifteen per cent of white adults in developed countries harbour gallstones. Frequency is further reduced in Black Americans, East Asia and sub-Saharan Africa. In developed countries, cholesterol gallstones predominate; 15% are black pigment. East Asians develop brown pigment stones in bile ducts, associated with biliary infection or parasites, or in intrahepatic ducts (hepatolithiasis). Certain risk factors for gallstones are immutable: female gender, increasing age and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis, Crohn's disease) and gallbladder stasis (from spinal cord injury or drugs like somatostatin). The only established dietary risk is a high caloric intake. Protective factors include diets containing fibre, vegetable protein, nuts, calcium, vitamin C, coffee and alcohol, plus physical activity.

    Although experimentally induced cholesterol gallstone formation has been associated with altered gallbladder (GB) absorption and increased biliary Ca2+, the relationship between these events remains unclear. Recent studies suggest that extracellular Ca2+ ([Ca2+]ec) influences GB ion transport. Whether the effects of [Ca2+]ec are mediated by changes in intracellular Ca2+ ([Ca2+]ic) has not been determined. This study was designed to define the effects of altered [Ca2+]ic on GB ion transport. Prairie dog GBs were mounted in a Ussing chamber and short-circuit current (Isc), potential difference (Vms), and resistance (Rt) were recorded. Mucosal surfaces were exposed to either Dantrolene (Dt) or nickel (Ni2+). Dt "traps" [Ca2+]ic within intracellular organelles, thereby lowering cytosolic Ca2+; and Ni2+ prevents influx of [Ca2+]ec, presumably by binding Ca2+ channels. Although Dt reduced both Isc and Vms (P less than 0.01), these effects were transient. Transport recovery was probably due to increased [Ca2+]ec influx with restoration of [Ca2+]ic. Ni2+ resulted in sustained decreases in Isc and Vms (P less than 0.05) despite subsequent addition of 10 mM Ca2+. These findings are consistent with the prevention of [Ca2+]ec influx by Ni2+. We conclude that: (1) [Ca2+]ic may be a modulator of GB ion transport and (2) previously reported [Ca2+]ec effects on ion transport may be mediated through [Ca2+]ic concentration changes.

  8. In vivo gallbladder absorption: a new dual-isotope technique

    Available methods for measuring in vivo gallbladder absorption preclude the use of animals in which hepatic bile enters the gallbladder via accessory or aberrant channels. However, accessory bile ducts are present in many of the animal models currently used in gallstone research. The aim of this study, therefore, was to evaluate a new dual-isotope technique that corrects for accessory bile flow and to compare data on electrolyte and water absorption with those derived from the standard, single-isotope technique. Prairie dogs underwent gallbladder exclusion by cystic duct ligation and common bile duct cannulation. Carbon 14-polyethylene glycol-labeled lactated Ringer's solution was instilled into the gallbladder while tritiated cholic acid was administered intravenously to label the bile acid pool. There is no correlation between water or electrolyte absorption and time, nor between water and electrolyte absorption, when these parameters are calculated by the standard, single-isotope technique. In contrast, use of the dual-isotope technique quantifies accessory bile duct flow and yields a linear increase in water and electrolyte absorption, both of which are time dependent. These data suggest that the dual-isotope technique provides a means to accurately measure in vivo gallbladder absorption in animals with or without accessory bile ducts.

    Congenital choledochal cyst is a rarely seen malformation of childhood, particularly when associated with multiseptate gallbladder or ectopic pancreas. The current case represents a 15-day-old boy with jaundice. Ultrasonography suggested a cystic lesion, probably of the common bile duct. The patient underwent a total excision of type I choledochal cyst and gallbladder with Roux-en-Y anastomosis, and a wedge biopsy from the liver. Gross examination revealed multiple septa dividing the gallbladder into multiple compartments. The outer and inner surfaces of the choledochal cyst were unremarkable. Microscopically, the cyst wall was composed of dense fibrous tissue with a single layer of cubic to columnar cells constituting the overlying epithelium. Serial sections incidentally revealed ectopic pancreatic tissue lying along the cyst wall characterized by acini, islets, and ductal structures with endocrine cells reactive for chromogranin A. Septa dividing the gallbladder were composed of fibrotic stalks containing smooth muscle fibers. Areas of papillary hyperplasia and intestinal metaplasia of gallbladder epithelium were also noted. The liver biopsy specimen demonstrated the presence of intrahepatic bile ducts, subsequently confirmed by cytokeratin 7. To our knowledge, this case represents the 1st one associated with these 3 entities and only the 2nd choledochal cyst with ectopic pancreatic tissue in its wall.

  10. A decade of experience with injuries to the gallbladder

    2010-01-01

    Background Considering that injuries to the gallbladder are rare, the purpose of this study was to evaluate injury patterns, operative procedures and outcomes in patients with trauma to the gallbladder. A retrospective review of traumatic injuries to the gallbladder at an urban level 1 trauma center from 1996 to 2008 was performed. Injuries were identified via imaging or during operative exploration. Results Injuries to the gallbladder occurred in 45 patients, 40 (89%) of whom suffered penetrating trauma. Associated injuries were present in 44 (98%) patients, including 10 (22%) pancreatic injuries requiring repair and/or drainage. Patients were severely injured (49% hemodynamically unstable at presentation; mean Injury Severity Score = 20; mean length of stay = 22 days; mortality rate = 24%). Cholecystectomy was performed in 42 patients (93%), while the remaining 3 had drainage only as part of a "damage control" operation related to their critical physiologic status. Injuries to the extrahepatic biliary ducts occurred in 3 patients (7%) as well. Although all patients developed trauma related complications, none were a direct result of their biliary tract injuries. Conclusion Injuries to the gallbladder are rare even in the busiest urban trauma centers. Almost all patients have associated intra-abdominal injuries, and nearly 50% of patients are hemodynamically unstable on admission. Rapid cholecystectomy is the treatment of choice for all mechanisms of injury, except when the first operative procedure is of the damage control type. PMID:20398307

    Gallbladder cancer is a highly aggressive disease with poor prognosis that is two to six times more frequent in women than men. The development of gallbladder cancer occurs over a long time (more than 15 y) and evolves from chronic inflammation to dysplasia/metaplasia, carcinoma in situ, and invasive carcinoma. In the present study we found that, in female mice in which the oxysterol receptor liver X receptor-beta (LXRbeta) has been inactivated, preneoplastic lesions of the gallbladder developed and evolved to cancer in old animals. LXRbeta is a nuclear receptor involved in the control of lipid homeostasis, glucose metabolism, inflammation, proliferation, and CNS development. LXRbeta(-/-) female gallbladders were severely inflamed, with regions of dysplasia and high cell density, hyperchromasia, metaplasia, and adenomas. No abnormalities were evident in male mice, nor in LXRalpha(-/-) or LXRalpha(-/-)beta(-/-) animals of either sex. Interestingly, the elimination of estrogens with ovariectomy prevented development of preneoplastic lesions in LXRbeta(-/-) mice. The etiopathological mechanism seems to involve TGF-beta signaling, as the precancerous lesions were characterized by strong nuclear reactivity of phospho-SMAD-2 and SMAD-4 and loss of E-cadherin expression. Upon ovariectomy, E-cadherin was reexpressed on the cell membranes and immunoreactivity of pSMAD-2 in the nuclei was reduced. These findings suggest that LXRbeta in a complex interplay with estrogens and TGF-beta could play a crucial role in the malignant transformation of the gallbladder epithelium.

  12. New approach to gallbladder ultrasonic images analysis and lesions recognition.

    2009-03-01

    This paper presents a new approach to gallbladder ultrasonic image processing and analysis towards detection of disease symptoms on processed images. First, in this paper, there is presented a new method of filtering gallbladder contours from USG images. A major stage in this filtration is to segment and section off areas occupied by the said organ. In most cases this procedure is based on filtration that plays a key role in the process of diagnosing pathological changes. Unfortunately ultrasound images present among the most troublesome methods of analysis owing to the echogenic inconsistency of structures under observation. This paper provides for an inventive algorithm for the holistic extraction of gallbladder image contours. The algorithm is based on rank filtration, as well as on the analysis of histogram sections on tested organs. The second part concerns detecting lesion symptoms of the gallbladder. Automating a process of diagnosis always comes down to developing algorithms used to analyze the object of such diagnosis and verify the occurrence of symptoms related to given affection. Usually the final stage is to make a diagnosis based on the detected symptoms. This last stage can be carried out through either dedicated expert systems or more classic pattern analysis approach like using rules to determine illness basing on detected symptoms. This paper discusses the pattern analysis algorithms for gallbladder image interpretation towards classification of the most frequent illness symptoms of this organ.

    Backgrounds/Aims We investigated patients' clinical and radiological data to determine preoperative factors that predict cholesterol gallbladder (GB) polyps of large size, which can be helpful for decision on further diagnostic tools. Methods In this study, we retrospectively analyzed 126 patients who underwent laparoscopic cholecystectomy for GB polyps >10 mm diagnosed preoperatively by abdominal ultrasonography between February 2002 and February 2016 in Department of Surgery, Sanggye Paik Hospital. Patients were divided into non-cholesterol polyps group and cholesterol polyps group, based on the postoperative pathologic diagnosis. Clinical and radiological data, such as gender, age, body weight, height, body mass index (BMI), laboratory findings, size, number and shape of the polypoid lesions, and presence of the concurrent GB stone were compared between the two groups. Results Of the 126 cases, 73 had cholesterol polyps (57.9%) and 53 cases were non-cholesterol polyps (42.1%). The younger age (<48.5 years), size of polyp <13.25 mm and multiple polyps were independent predictive variables for cholesterol polyps, with odd ratios (OR) of 2.352 (p=0.045), 5.429 (p<0.001) and 0.472 (p<0.001), respectively. Conclusions Age, size and polyp number were used to predict cholesterol GB polyp among polypoid lesions of the gallbladder >10 mm. For cases in which these factors are not applicable, it is strongly recommended to evaluate further diagnostic tools, such as computed tomography, endoscopic ultrasonography and tumor markers.

    There are medical conditions where the etiology is not at the level of digestive system, but as a result of a distant lesion, determined by head trauma. The latter is a severe impact on the whole body, not only locally; it produces damages in the gastro-duodenal area mainly as acute stress ulcer. Our study includes 4 cases of patients with multiple trauma, admitted in the "St. Pantelimon" Emergency Hospital, where, despite medication, they subsequently developed stress ulcer (Cushing ulcer). Laboratory tests were followed in the development the level of leukocytes, ESR(erythrocyte sedimentation rate) and abdominal ultrasound. Around the fifth day it was observed that the level of the leukocytes were high (between 15000-20000/microl). ESR between 40-70mm/hour and ultrasound showed fluid in peritoneal cavity, mainly in subhepatic space (Morison's pouch). A positive radiological result highlight the crescent transparency (mesogastric pneumoperitoneum) in dorsal decubitus position, lateral incidence (pacients that could not be mobilised and the radiologic exam was made in intensive care bed). On the group of four patients studied with multiple trauma and Cushing ulcer perforation, it was laparoscopically intervined in order to reduce the negativ effects of combined anesthesic and surgical trauma on an already fragile status. The study showed that emergency laparoscopy in patients with multiple trauma is a successful approach in it's minimally invasivity, being a diagnosis and therapeutic first option in acute abdominal conditions in these patients.

    2016-11-01

    The aim was to describe the management of benign gallbladder disease and identify characteristics associated with all-cause 30-day readmissions and complications in a prospective population-based cohort. Data were collected on consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing all-cause 30-day readmissions and complications were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2). Data were collected on 8909 patients undergoing cholecystectomy from 167 hospitals. Some 1451 cholecystectomies (16·3 per cent) were performed as an emergency, 4165 (46·8 per cent) as elective operations, and 3293 patients (37·0 per cent) had had at least one previous emergency admission, but had surgery on a delayed basis. The readmission and complication rates at 30 days were 7·1 per cent (633 of 8909) and 10·8 per cent (962 of 8909) respectively. Both readmissions and complications were independently associated with increasing ASA fitness grade, duration of surgery, and increasing numbers of emergency admissions with gallbladder disease before cholecystectomy. No identifiable hospital characteristics were linked to readmissions and complications. Readmissions and complications following cholecystectomy are common and associated with patient and disease characteristics. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Cytokeratins (CKs) 8 and 18 are normally expressed in simple epithelia. This unique pair of CKs is believed to be involved in hepatic diseases and many human cancers. Little is known about the role of tissue expression of both CKs in patients with cholelithiasis (CH). The aim of the study was to analyse tissue expression of CK8 and 18 in the specimens of gallbladder mucosa in 35 young (up to 25 years of age) and 20 older patients (approximately 50 years of age) with CH. An immunocytochemical ABC method and the spatial visualization technique were conducted. Our study demonstrated significantly lower amounts of both CKs in young patients, as compared to older patients. The higher cellular expression of CK8 in older patients was linked to acute clinical course vs. chronic ones. Tissue expression of neither CK correlated with inflammatory activity (grading) of the gallbladder mucosa. A positive correlation between reciprocal expressions of the two CKs may confirm a cytoprotective role of the two proteins in both groups of patients with symptomatic CH. Significantly higher expression of CK18 than that of CK8 in younger patients suggests a different role of CK8 and 18 in lithogenesis in this group.

    A 43-year-old man presented to the hospital with haemoptysis. When worked up, his history and examination were highly suggestive of pulmonary tuberculosis (TB). He subsequently developed a massive upper gastrointestinal bleed and underwent an emergency laparotomy, which revealed a massively dilated caecum measuring ∼20 cm in diameter. The caecum had perforated due to acute decompensation of intestinal TB. Though common in developing countries, TB is rare in the UK, especially the intestinal kind. The most striking feature of this case is, however, the size of the caecal distension caused by the tubercular inflammation and subsequent perforation—something unheard of in the literature. This massive caecal distention would be explained by the Law of Laplace. In conclusion, massive distension and caecal perforation are possible consequences of intestinal TB, especially in the 48–72 h immediately after starting anti-tubercular therapy. PMID:25972412

    Superficial ulnar artery is a rare finding but shows significant surgical implications. Its thinness and pliability make this flap an excellent solution for soft tissue reconstruction, especially in the head and neck region. We hereby report a successful free superficial ulnar artery perforator forearm flap transfer for tongue reconstruction. A 64-year-old man presenting with a squamous cell carcinoma of the left tongue underwent a wide resection of the tumor, left radical neck dissection, and reconstruction of the tongue and the left tonsillar pillar with the mentioned flap. No complications were observed postoperatively. The flap survived completely; no recurrence at 6 months of follow-up was detected. Superficial ulnar artery perforator flap has shown to be a safe alternative to other free tissue flaps in specific forearm anatomic conditions.

    Bladder perforation by ventriculoperitoneal shunt is a rare complication that has been describe in 19 cases in prior literature. This work describes the case of a 4-month-old baby who presented with extrusion of the distal catheter through the urethra. The patient underwent a laparotomy; the catheter was cut close to the bladder wall and repositioned into the peritoneal cavity. The bladder wall was sutured, and the remaining distal portion of the catheter was removed through the urethra. Based on this single experience and a literature review, the authors classified the clinical signs and symptoms of bladder perforation by the ventriculoperitoneal shunt catheter. Finally, the authors propose a more conservative approach for this rare complication.

    The medial sural artery supplies the medial gastrocnemius muscle and sends perforating branches to the skin. The possible use of these musculocutaneous perforators as the source of a perforator-based free flap was investigated in cadavers. Ten legs were dissected, and the topography of significant perforating musculocutaneous vessels on both the medial and the lateral gastrocnemius muscles was recorded. A mean of 2.2 perforators (range, 1 to 4) was noted over the medial gastrocnemius muscle, whereas in only 20 percent of the specimens was a perforator of moderate size noted over the lateral gastrocnemius muscle. The perforating vessels from the medial sural artery clustered about 9 to 18 cm from the popliteal crease. When two perforators were present (the most frequent case), the perforators were located at a mean of 11.8 cm (range, 8.5 to 15 cm) and 17 cm (range, 15 to 19 cm) from the popliteal crease. A series of six successful clinical cases is reported, including five free flaps and one pedicled flap for ipsilateral lower-leg and foot reconstruction. The dissection is somewhat tedious, but the vascular pedicle can be considerably long and of suitable caliber. Donor-site morbidity was minimal because the muscle was not included in the flap. Although the present series is short, it seems that the medial sural artery perforator flap can be a useful flap for free and pedicled transfer in lower-limb reconstruction.

    A combined septal perforation repair and rhinoplasty was performed in 80 patients presenting with septal perforations (size 1 to 5 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. Complete closure of the perforation was achieved in 90% of perforations of size up to 3.5 cm and in only 70% of perforations that were larger than 3.5 cm. Cosmetically, 95% were very satisfied with their aesthetic result. The external rhinoplasty approach proved to be very helpful in the process of septal perforation repair especially in large and posteriorly located perforations and in cases where the caudal septal cartilage was previously resected. Our results show that septal perforation repair can be safely combined with rhinoplasty and that some of the routine rhinoplasty maneuvers, such as medial osteotomies and dorsal lowering, could even facilitate the process of septal perforation repair.

    Metachromatic leukodystrophy (MLD) is an autosomal recessive lysosomal storage disease caused by deficient activity of arylsulfatase A, leading to an accumulation of sulfatide in myelinating cells and progressive central and peripheral demyelination. Sulfatide also accumulates in various organs, most notably the gallbladder. Gallbladder mucosal hyperplasia with papillomatosis, in the setting of abdominal pain and hemobilia, is often demonstrated by sonography. We present a histologic and ultrastructural description of these alterations in a 5-year-old girl with MLD who presented with abdominal pain and feeding intolerance. Gross and light microscopic analysis demonstrated diffuse villous hyperplasia of the gallbladder mucosa with intraepithelial and intravillous macrophage accumulations of metachromatic material. Electron microscopic analysis demonstrated this material to comprise numerous membrane-bound inclusions composed of concentrically lamellated, dense material. The rarity of descriptions of this finding prompted this case report.

By this intention, they theorize a correlation between genetic modifications (which are responsible of malignant transformation of biliary epithelium) and some intestinal infections. From 1999 to 2004 they observed 15 GBC and all 15 gallbladder have been analyzed histologically and from microbiological aspect; by these means from 1999 till 2004 they have studied also 30 persons with colelithiasis. The authors noticed that bile of both groups contained, in three cases in the first and in 8 cases in the second, a germ named Escherichia Coli which normally lives in intestine, while in 10 operated gallbladders of the first group and 12 of the second there was a positive for k-ras. They are studying to confirm their theories.

(IM) and its risk factors. IM was positive in 39% of 293 patients tested, and in the comparative analysis of 114 metaplasia positive versus 179 negative patients, a high risk was found in patients who were 60 years or older [adjusted odds ratio (aOR) = 3.0, 95% confidence interval (CI): 1.5, 6.2]. Other factors with aOR greater than 1 were moderate to excessive use of chilies (1.8) and ethnic origin of North India (1.7). Screening method has yet to be devised for early detection of gallbladder cancer by identifying metaplastic lesions early in life. We believe that large geographic variation and lifestyle environmental factors associated with the development of gallbladder metaplasia and cancer mortality are concealed in our study that needs to be further explored.

It was analyzed immediate results of surgical treatment of 646 patients with perforative gastroduodenal ulcer. Ulcer suturing predominated as surgical technique (358 patients, 55.5%), in other observations there were different types of vagotomy (215 cases, 33.3%), partial gastrectomy in 73 (11.2%) patients. In early postoperative period 36 (5.62%)patients died, incidence of complications was 6.2%. Following aspects effect on choice of surgical techbique including laoarotomy or minimally invasive approach, conventional suturing, vagotomy, partial gastrectomy: 1. presence of shock or unstable hemodynamics; 2. life-threating comorbidities (ASA class 3 and higher); 3. degree of abdominal bacterial contamination; 4. pre-hospital duration of disease; 5. dimension and type of ulcer; 6. ulcerative history or intraoperative evidence of chronic ulcer. Implementation or absolute predominance of surgery of the same type (suturing of perforative ulcer) leads to great number of poor long-term results (up to 60-70%) and requires repeated interventions.

    Eleven patients with suspected acute cholecystitis underwent sequential {sup 99}mTc-iminodiacetic derivative (IDA) and {sup 111}In-white blood cell (WBC) imaging to determine if {sup 111}In-WBCs accumulate within an acutely inflamed hemorrhagic gallbladder wall and, thus, could be employed as a reasonable alternative to {sup 99}mTc-IDA scintigraphy in detecting acute cholecystitis. Seven patients had surgically confirmed acute cholecystitis. Of these cases, five had a true-positive {sup 99}mTc-IDA and {sup 111}In-WBC, one an indeterminate {sup 111}In-WBC and true-positive {sup 99}mTc-IDA, and one a true-positive {sup 111}In-WBC and false-negative {sup 99}mTc-IDA scan. The remaining four patients did not have acute cholecystitis. All visualized their gallbladder within 1 hr after {sup 99}mTc-IDA administration and none had {sup 111}In-WBC gallbladder wall uptake. Both {sup 111}In-WBC and {sup 99}mTc-IDA scintigraphy accurately detected acute cholecystitis: hepatobiliary scintigraphy demonstrated a cystic duct obstruction and {sup 111}In-WBC imaging detected the inflammatory infiltrate within the gallbladder wall. The sensitivity and specificity of each was 86% and 100%, respectively.

    Attempts to remove the gallbladder by non-surgical means began in the 1980's, by applying chemicals, heat or laser to remove its mucosa and reduce it to an innocuous scar. The aim of this work is to determine whether complete ablation of this organ is possible using total ablation by applying a diode laser. Thirty rabbits were divided into 3 groups of 10 animals. The gallbladder was surgically accessed and a 980 nm diode laser was applied endoluminally using fibre optics until it shrunk. Ethanol was used as a sclerosing agent plus a fibrin tail to seal the gallbladder lumen in one of the control groups, and a physiological solution was used in the rest. The animals were slaughtered at 65 days and the results of the procedure were observed macroscopically and histologically, evaluating the remains of the gallbladder lumen, fibrosis, and areas of re-epithelialisation. Statistical analysis was made using the Fisher test. Eight of the gallbladders treated by laser disappeared leaving a small sub-hepatic scar. There were no complications during or after surgery. The results were successful in only case in the ethanol group, and there was no ablation with physiological solution. The comparison of the results showed a significant positive difference in the group treated with laser compared to those with ethanol plus fibrin tail (P<.0055) and the physiological solution (P<.0007). Ablation of the gallbladder using a diode laser was possible in this experimental model. Copyright © 2011 AEC. Published by Elsevier Espana. All rights reserved.

    2005-10-01

    The angioarchitecture of extrahepatic bile ducts and gallbladder of the miniature rabbit was studied by scanning electron microscopy (SEM) of vascular corrosion casts. Light microscopy of Masson-stained, paraffin-embedded transverse tissue sections served to attribute cast vascular structures to defined layers of bile ducts and gallbladder. In all segments of the bile tract, a mucosal and a subserosal vascular network was found. In glandular segments, the mucosal network was composed of a meshwork of subepithelial and circumglandular capillaries, which serve the mucosal functions. Differences in the angioarchitectonic patterns existed only in the subserosal networks as hepatic ducts own one supplying arteriole only, while the common bile duct owns a well-defined rete arteriosum subserosum. A well-developed dense subserosus venous plexus was present throughout the bile tract. Vascular patterns of the gallbladder body resembled those of the bile duct, whereby the dense subserous venous plexus was located close to the mucosal capillary network. The subserosal network in the neck of the gallbladder resembled that of the cystic duct. Spatial changes of the mucosal vascular network during volume changes of the gallbladder were documented. Measurements from tissue sections revealed bile tract diameters of 220-400 microm (extrahepatic ducts), 500-650 microm (cystic duct), and 4-6 mm (common bile duct). Data gained from high-powered SEM micrographs of vascular corrosion casts revealed vessel diameters of 200 microm (cystic artery), 90-110 microm (cystic vein), 30-40 microm (feeding arterioles), and 25-110 microm (subserosal venules). Crypt diameters in the filled gallbladder were 300-1,500 mum; those in the contracted organ were 100-600 microm.

    Calcium sensitization is an important physiological process in agonist-induced contraction of smooth muscle. In brief, calcium sensitization is a pathway that leads to smooth muscle contraction independently of changes in [Ca(2+)](i) by mean of inhibition of myosin light chain phosphatase. Aging has negative impacts on gallbladder contractile response due to partial impairment in calcium signaling and alterations in the contractile machinery. However, information regarding aging-induced alterations in calcium sensitization is scanty. We hypothesized that the calcium sensitization system is negatively affected by age. To investigate this, gallbladders were collected from adult (4 months old) and aged (22-24 months old) guinea pigs. To evaluate the contribution of calcium sensitization pathways we assayed the effect of the specific inhibitors Y-27632 and GF109203X on the "in vitro" isometric gallbladder contractions induced by agonist challenges. In addition, expression and phosphorylation (as activation index) of proteins participating in the calcium sensitization pathways were quantified by Western blotting. Aging reduced bethanechol- and cholecystokinin-evoked contractions, an effect associated with a reduction in MLC20 phosphorylation and in the effects of both Y-27632 and GF109203X. In addition, there was a drop in ROCK I, ROCK II, MYPT-1 and PKC expression and in the activation/phosphorylation of MYPT-1, PKC and CPI-17 in response to agonists. Interestingly, melatonin treatment for 4 weeks restored gallbladder contractile responses due to re-establishment of calcium sensitization pathways. These results demonstrate that age-related gallbladder hypocontractility is associated to alterations of calcium sensitization pathways and that melatonin treatment exerts beneficial effects in the recovery of gallbladder contractility.

    Background/Aims Gallbladder polyps (GBP) are a common clinical finding and may possess malignant potential. We conducted this study to determine whether visceral obesity is a risk factor for GBP. Methods We retrospectively reviewed records of subjects who received both ultrasonography and computed tomography with measurements of the areas of visceral adipose tissue and total adipose tissue (TAT) on the same day as health checkups. Results Ninety-three of 1,615 subjects (5.8%) had GBP and were compared with 186 age- and sex-matched controls. VAT (odds ratio [OR], 2.941; 95% confidence interval [CI], 1.325 to 6.529; p=0.008 for the highest quartile vs the lowest quartile) and TAT (OR, 3.568; 95% CI, 1.625 to 7.833; p=0.002 for the highest quartile vs the lowest quartile) were independent risk factors together with hypertension (OR, 2.512; 95% CI, 1.381 to 4.569; p=0.003), diabetes mellitus (OR, 2.942; 95% CI, 1.061 to 8.158; p=0.038), hepatitis B virus positivity (OR, 3.548; 95% CI, 1.295 to 9.716; p=0.014), and a higher level of total cholesterol (OR, 2.232; 95% CI, 1.043 to 4.778; p=0.039 for <200 mg/dL vs ≥240 mg/dL). Body mass index and waist circumference were not meaningful variables. Conclusions Visceral obesity measured by VAT and TAT was associated with GBP irrespective of body mass index or waist circumference. PMID:26260756

    To determine the factors affecting the decision to perform surgery, and the efficiency of ultrasonography (USG) in detecting gallbladder polyps (GP). Data for 138 patients who underwent cholecystectomy between 1996 and 2012 in our clinic with a diagnosis of GP were retrospectively analyzed. Demographic data, clinical presentation, principal symptoms, ultrasonographic and histopathological findings were evaluated. Patients were evaluated in individual groups according to the age of the patients (older or younger than 50 years old) and polyp size (bigger or smaller than 10 mm) and characteristics of the polyps (pseudopolyp or real polyps). χ(2) tests were used for the statistical evaluation of the data. The median age was 50 (26-85) years and 91 of patients were female. Of 138 patients who underwent cholecystectomy with GP diagnosis, only 99 had a histopathologically defined polyp; 77 of them had pseudopolyps and 22 had true polyps. Twenty-one patients had adenocarcinoma. Of these 21 patients, 11 were male, their median age was 61 (40-85) years and all malignant polyps had diameters > 10 mm (P < 0.0001). Of 138 patients in whom surgery were performed, 112 had ultrasonographic polyps with diameters < 10 mm. Of the other 26 patients who also had polyps with diameters > 10 mm, 22 had true polyps. The sensitivity of USG was 84.6% for polyps with diameters > 10 mm (P < 0.0001); however it was only 66% in polyps with diameters < 10 mm. The risk of malignancy was high in the patients over 50 years old who had single polyps with diameters > 10 mm.

  19. Medial and lateral perforant path evoked potentials are selectively modulated by pairing with glutamatergic activation of locus coeruleus in the dentate gyrus of the anesthetized rat.

    Norepinephrine (NE) in vitro produces long-lasting potentiation of medial perforant path input and depression of lateral perforant path input to dentate gyrus in the rat. Similar, but highly transient, effects have been reported in vivo using paragigantocellular stimulation to release NE. The present study uses alternate stimulation of the medial perforant path and lateral olfactory tract (eliciting a lateral perforant path-evoked potential) to examine the effects of glutamatergic activation of locus coeruleus (LC) on the two pathways for up to 3 h post-LC activation. In the first experiment, the expected potentiation of the medial perforant path population spike in dentate gyrus was observed, but without accompanying depression of the lateral perforant path-mediated evoked potential (lateral olfactory tract stimulation, 60 s ISI). In a second experiment, with more frequent pairing of input with NE release (10 s ISI), significant potentiation of lateral perforant path-mediated input to dentate gyrus occurred, but potentiation of medial perforant path input was not seen. A third experiment with a 30 s ISI again produced potentiation of lateral perforant path-mediated input without potentiation of the medial perforant path population spike. The size of effects with the 30 s ISI was intermediate between that seen with 10 s and 60 s ISI. Potentiation of lateral perforant path over medial perforant path input has previously been reported with acute nicotinic activation of the LC. This outcome also resembles heterosynaptic modulation previously reported with tetanic potentiation. The data argue for a competitive relationship between medial and lateral perforant path inputs to dentate gyrus and suggest pairing with increased NE produces a bias favoring one or the other pathway depending on parameters such as strength and frequency. NE potentiating effects on lateral perforant path input here may also have occurred in entorhinal cortex (EC) given the system-wide NE release

    For the successful reconstruction of facial defects, various perforator flaps have been used in single-stage surgery, where tissues are moved to adjacent defect sites. Our group successfully performed perforator flap surgery on 17 patients with small to moderate facial defects that affected the functional and aesthetic features of their faces. Of four complicated cases, three developed venous congestion, which resolved in the subacute postoperative period, and one patient with partial necrosis underwent minor revision. We reviewed the literature on freestyle perforator flaps for facial defect reconstruction and focused on English articles published in the last five years. With the advance of knowledge regarding the vascular anatomy of pedicled perforator flaps in the face, we found that some perforator flaps can improve functional and aesthetic reconstruction for the facial defects. We suggest that freestyle facial perforator flaps can serve as alternative, safe, and versatile treatment modalities for covering small to moderate facial defects.

    Problems can be encountered inserting intraosseous injection needles through perforation sites. This in vitro study examined the variability and size compatibility of Stabident intraosseous injection components. The diameters of 40 needles and perforators from a single Stabident kit were measured in triplicate with a toolmakers microscope. One-way ANOVA revealed that mean needle diameter (0.411 mm) was significantly narrower than mean perforator diameter (0.427 mm) (p < 0.001). A frequency distribution plot revealed that needle diameter followed a normal distribution, indicating tight quality control during manufacture. The diameter of perforators was haphazardly distributed, with a clustering of 15% at the lower limit of the size range. However on no occasion was the diameter of a perforator smaller than that of an injection needle. We conclude that components of the Stabident intraosseous anaesthetic system are size-compatible, but there is greater and more haphazard variability in the diameter of perforators than injection needles.

    Cholecystolithiasis is a highly prevalent condition in the Western world. Gallbladder stone-related conditions represent the second most common gastrointestinal pathology. Cholesterol stones represent over 80% of gallstones. Cholesterol stones develop secondary to crystallization of bile cholesterol. Water resorption from gallbladder bile via aquaporin in the gallbladder mucosa might play a role in the development of cholesterol stones. This study investigated the expression of Aquaporin-1 (AQP1) and Aquaporin-8 (AQP8) in the human gallbladder mucosa and their possible association with the formation of gallbladder stones. The expression of AQP1 and AQP8 in the gallbladder mucosa was examined via immunohistochemical staining. The expression of both AQP1 and AQP8 in the gallbladder mucosa of stone carriers (study group) was compared to that of nonstone carriers (control group). Eighty-four gallbladder specimens from 44 male (52·2%) and 40 female (47·6%) patients were analysed. The study group included 47 specimens from stone carriers, while 37 specimens from stone-free gallbladders were included in the control group. Immunostaining for both AQP1 and AQP8 was positive in 80 cases. AQP1 was expressed both over the apical and intercellular membrane, while AQP8 was expressed only over the apical membrane. A similar distribution was recorded in specimens from the cystic duct. Immunostaining with AQP1 was generally stronger in comparison with AQP8. No significant (P > 0·05) relationship was found between aquaporin expression and the presence or absence of gallbladder stones. AQP1 and AQP8 are both expressed in the gallbladder and cystic duct mucosa. However, their role in the development of gallbladder stones is still to be proven. © 2015 Stichting European Society for Clinical Investigation Journal Foundation.

    Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity. PMID:25692425

    Treatment guidelines recommend watchful waiting for children older than 2 years with acute otitis media (AOM) without perforation, unless they are at high risk of complications. The high prevalence of chronic suppurative otitis media (CSOM) in remote Aboriginal and Torres Strait Islander communities leads these children to be classified as high risk. Urban Aboriginal and Torres Strait Islander children are at lower risk of complications, but evidence to support the subsequent recommendation for watchful waiting in this population is lacking. This non-inferiority multi-centre randomised controlled trial will determine whether watchful waiting is non-inferior to immediate antibiotics for urban Aboriginal and Torres Strait Islander children with AOM without perforation. Children aged 2 - 16 years with AOM who are considered at low risk for complications will be recruited from six participating urban primary health care services across Australia. We will obtain informed consent from each participant or their guardian. The primary outcome is clinical resolution on day 7 (no pain, no fever of at least 38 °C, no bulging eardrum and no complications of AOM such as perforation or mastoiditis) as assessed by general practitioners or nurse practitioners. Participants and outcome assessors will not be blinded to treatment. With a sample size of 198 children in each arm, we have 80 % power to detect a non-inferiority margin of up to 10 % at a significance level of 5 %, assuming clinical improvement of at least 80 % in both groups. Allowing for a 20 % dropout rate, we aim to recruit 495 children. We will analyse both by intention-to-treat and per protocol. We will assess the cost- effectiveness of watchful waiting compared to immediate antibiotic prescription. We will also report on the implementation of the trial from the perspectives of parents/carers, health professionals and researchers. The trial will provide evidence for the safety and effectiveness of watchful waiting

    Objective Aberrant expression of maspin protein related to DNA hypomethylation in the promoter region is frequently observed in gallbladder carcinomas, whereas the non‐tumorous gallbladder epithelium is maspin negative. We investigated maspin expression in non‐tumorous gallbladder epithelium in patients with cholelithiasis. Methods An immunohistochemical study of maspin expression was performed in 69 patients with cholelithiasis and 30 patients with gastric cancer without cholelithiasis. Results Immunoreactivity for maspin was observed in focal and patchy regions of the gallbladder epithelium. Positive immunoreactivity for maspin was significantly associated with the presence of intestinal metaplasia in patients with cholelithiasis (p<0.05). Conclusion The high incidence of aberrant maspin expression in both intestinal metaplasia and carcinoma of the gallbladder supports the assumption that intestinal metaplasia of the gallbladder may predispose to gallbladder carcinoma.

    A 65-year-old female who presented with back pain was diagnosed to have the presence of biliary sludge in the gallbladder. Computed tomography showed that the round ligament connected to the left portal umbilical portion was in the normal anatomical position. However, the gallbladder was located to the left of the middle hepatic vein and the round ligament, attached to the left lateral segment of the liver. The right posterior portal vein diverged alone from the main portal vein, and there was a long stem from the right anterior and left portal veins. Laparoscopic cholecystectomy confirmed the abnormal location of the gallbladder. Most reported cases of left-sided gallbladder are caused by a right-sided round ligament, which is called a "false" left-sided gallbladder. A case of left-sided gallbladder with a normal left-sided round ligament, which is designated as a case of "true" left-sided gallbladder, is extremely rare.

    2010-01-01

    Perforation of esophagus in the adult is a very morbid condition with high morbidity and mortality. The ideal treatment is controversial. The main causes for esophageal perforation in adults are iatrogenic, traumatic, spontaneous and foreign bodies. The morbidity and mortality rate is directly related to the delay in diagnosis and initiation of optimum treatment. The reported mortality from treated esophageal perforation is 10% to 25%, when therapy is initiated within 24 hours of perforation, but it could rise up to 40% to 60% when the treatment is delayed beyond 48 hours. Primary closure of the perforation site and wide drainage of the mediastinum is recommended if perforation is detected in less than 24 hours. Treatment option for delayed or missed rupture of esophagus is not very clear and is controversial. Recently a substantial number of patients with esophageal perforation are being managed by nonoperative measures. Patients with small perforations and minimal extraesophageal involvement may be better managed by nonoperative treatment Major prognostic factors determining mortality are the etiology and site of the injury, the presence of underlying esophageal pathology, the delay in diagnosis and the method of treatment. For optimum outcome for management of esophageal perforations in adults a multidisciplinary approach is needed. PMID:27942303

    Delayed lead perforation (occurring more than 1 month after implantation) is a rare complication. Its pathophysiology and optimal management are currently unclear. Three cases of delayed lead perforation (6-10 month) were identified in patients with low-profile active fixation leads. All cases presented in a subacute fashion with pleuritic chest pain with confirmatory chest x-ray and device interrogation. Given the potential complications of a perforated lead, all cases had the lead extracted under TEE observation with cardiac surgery backup in the operating room. All patients tolerated extraction without complication. Based on these cases, we recommend a management scheme for patients who present with delayed lead perforation.

    Incompetent superficial veins are the most common cause of lower extremity superficial venous reflux and varicose veins; however, incompetent or insufficient perforator veins are the most common cause of recurrent varicose veins after treatment, often unrecognized. Perforator vein insufficiency can result in pain, skin changes, and skin ulcers, and often merit intervention. Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources. Advantages and disadvantages of each modality and knowledge on these treatments are required to adequately address perforator venous disease.

    AIM: To analyze the association between Helicobacter spp. and some common gut bacteria in patients with cholecystitis. METHODS: A nested-polymerase chain reaction (PCR), specific to 16S rRNA of Helicobacter spp. was performed on paraffin-embedded gallbladder samples of 100 cholecystitis and 102 control cases. The samples were also analyzed for some common gut bacteria by PCR. Positive samples were sequenced for species identification. RESULTS: Helicobacter DNA was found in seven out of 100 cases of acute and chronic cholecystitis. Sequence analysis displayed Helicobacter pullorum (H. pullorum) in six cases and Helicobacter pylori in one; H. pullorum was only found in cases with metaplasia. Control samples were negative for Helicobacter spp. and some common gut bacteria. There was a significant difference (P = 0.007) between cholecystitis and control samples for Helicobacter DNA. CONCLUSION: A possible relationship was detected between Helicobacter DNA and cholecystitis. Further serological and immunohistochemical studies are needed to support these data. PMID:20939110

    The purpose of this study was to investigate the relationship between perforated appendicitis and patient with diabetes using a population-based data set. This study used data from the Longitudinal Health Insurance Database 2005 in Taiwan. We identified 4,806 patients hospitalized with acute appendicitis. The independent variable was whether a patient had ever received a diagnosis of diabetes before the index hospitalization. We performed a conditional logistic regression model to explore the odds ratio and its corresponding 95% confidence interval of perforated appendicitis. Rates of perforated appendicitis for patients with and those without diabetes were 46.2% and 28.3%, respectively. A chi-square test revealed that there was a significant difference in rates of perforated appendicitis between patients with and those without diabetes (P < .001). The conditional logistic regression model revealed that the adjusted odds ratio of perforated appendicitis for patients with diabetes was 1.35 (95% confidence interval = 1.11 to 1.65) compared with patients without diabetes. Our study demonstrated that a history of diabetes is an important factor with regard to the rate of perforated appendicitis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Gastrointestinal perforations, leaks and fistulas may be serious and life-threatening. The increasing number of endoscopic procedures with a high risk of perforation and the increasing incidence of leakage associated with bariatric operations call for a minimally invasive treatment for these complications. The therapeutic approach can vary greatly depending on the size, location, and timing of gastrointestinal wall defect recognition. Some asymptomatic patients can be treated conservatively, while patients with septic symptoms or cardio-pulmonary insufficiency may require intensive care and urgent surgical treatment. However, most gastrointestinal wall defects can be satisfactorily treated by endoscopy. Although the initial endoscopic closure rates of chronic fistulas is very high, the long-term results of these treatments remain a clinical problem. The efficacy of endoscopic therapy depends on several factors and the best mode of treatment will depend on a precise localization of the site, the extent of the leak and the endoscopic appearance of the lesion. Many endoscopic tools for effective closure of gastrointestinal wall defects are currently available. In this review, we summarized the basic principles of the management of acute iatrogenic perforations, as well as of postoperative leaks and chronic fistulas of the gastrointestinal tract. We also described the effectiveness of various endoscopic methods based on current research and our experience. PMID:26457014

  17. Regulation of gallbladder ion transport: role of biliary lipids.

    Recent studies indicate that biliary lipids influence in vivo gallbladder absorption and solute-coupled water flow. To clarify the electrophysiologic effects that underlie this phenomenon, prairie dog gallbladders were mounted in an Ussing-type chamber, and the influence of bile acids and varying ratios of bile acids and biliary phospholipids on transepithelial potential difference (Vms), resistance (Rt), and short-circuit current (Isc) was examined. Exposure to 5 mmol/L taurodeoxycholate (TDC) resulted in inhibition of Vms (p less than 0.01) and Isc (p less than 0.01) and an increase (p less than 0.05) in Rt. Subsequent perfusion with bile acids and phospholipids (5 mmol/L TDC + 0.3 mmol/L phosphatidylcholine [PC]) led to continued inhibition of ion transport. In contrast, exposure to 5 mmol/L TDC + 1.7 mmol/L PC resulted in a significant increase in transport, as manifested by an increase in Vms (p less than 0.02) and Isc (p less than 0.01) and a decrease in Rt (p less than 0.05) compared with bile acids. These results indicate that the ratio of phospholipids to bile salts modulates ion transport across prairie dog gallbladder and that this ratio may be an important determinant of gallbladder absorption in health and disease.

    A preliminary study of the relation between food intake and intensity of gallbladder bile on nuclear magnetic resonance (NMR) images was made. Twelve subjects (seven volunteers, five patients) were imaged following a minimum of 14 hours of fasting. Six of seven volunteers were reimaged one hour after stimulation by either a fatty meal or an alcoholic beverage. An additional seven patients were imaged two hours after a hospital breakfast. It was found that concentrated bile emits a high-intensity spin echo signal (SE), while hepatic bile in the gallbladder produces a low-intensity SE signal. Following ingestion of cholecystogogue, dilute hepatic bile settles on top of the concentrated bile, each emitting SE signals of different intensity. The average T1 value of concentrated bile was 594 msec, while the T1 vaue of dilute hepatic bile was 2,646 msec. The average T2 values were 104 msec for concentrated bile and 126 msec for dilute bile. The most likely cause for the different SE intensities of bile is the higher water content, and therefore longer T1 or T2 relaxation times, of hepatic bile. It is suggested that NMR imaging has the ability to provide physiological information about the gallbladder and that it may prove to be a simple and safe clinical test of gallbladder function.

    Survivin, a novel inhibitor of apoptosis, plays a role in oncogenesis and has been correlated with poor prognosis. We investigated its expression in gallbladder tissues of control, cholelithiasis, and gallbladder cancer (GBC). Survivin expression was correlated with different clinicopathologic parameters including prognosis in patients with GBC. Gallbladder tissue samples were collected from GBC (n = 39), cholelithiasis (n = 30), and control (n = 25). Expression of survivin messenger RNA (mRNA) was evaluated by real time polymerase chain reaction. Protein quantification was done by enzyme-linked immunosorbent assay. Significantly higher expression of survivin mRNA was observed in GBC (2.9-fold) and cholelithiasis (1.85-fold) as compared with control (P < 0.0001). In GBC, increased survivin expression (mRNA and protein) was significantly associated with higher tumor stage (stage III versus stage II) (P < 0.0001) and poor tumor differentiation (poor and moderate versus well) (P < 0.0001). No significant correlation was observed with any of the other clinicopathologic factors studied. Increased expression of survivin was associated with shorter survival (median survival 11.5 mo versus 18 mo). Differential expression of survivin in GBC suggests its possible role in gallbladder carcinogenesis. Its overexpression is associated with poor prognosis. Assessment of survivin might be used to stratify GBC patients for optimal treatment modalities, including targeted therapy. Copyright © 2015 Elsevier Inc. All rights reserved.

    Since stimuli from abdominal or pelvic viscera can affect respiratory muscle function, we hypothesized that mechanical stimulation of the gallbladder would result in inhibition of motor activity to the diaphragm and to upper airway muscles. We studied 12 decerebrate, vagotomized, paralyzed, artificially ventilated cats and recorded hypoglossal (HG) and phrenic (PHR) nerve activities while applying 600-1000 g of traction on the gallbladder during four respiratory cycles. Traction resulted in an initial reduction of PHR activity to 87.6+/-15.0% (mean+/-S.D.% of its baseline value), a reduction of HG activity to 74.2+/-27.5% and a lengthening of expiratory time to 178.8+/-81.0%. Subsequently, PHR activity and expiratory time returned toward control values, while HG remained diminished, at 66.4+/-19.1%. Our results show that mechanical stimulation of the gallbladder results in a respiratory inhibition with a disproportionate reduction in HG activity relative to PHR discharge. We speculate that gallbladder stimulation by contractions or surgery may compromise breathing by inhibition of phrenic discharge and upper airway obstruction.

    PubMed

    2017-06-01

    Nonoperative treatment of acute appendicitis is embraced by many surgical teams, driven by low to moderate quality randomized studies that support noninferiority of antibiotics versus appendectomy for treatment of acute uncomplicated appendicitis. Several flaws of these studies have emerged, especially in the recruitment strategy and in the diagnostic criteria that were used. The growing confidence given to antibiotics, together with the lack of reliable criteria to distinguish between uncomplicated and perforated appendicitis, exposes patients with perforated appendicitis to the likelihood to be treated with antibiotics instead of surgery. Among them, those patients who experience a temporary relief of symptoms due to antibiotics, followed by early recurrence of disease when antibiotics are discontinued, are likely to undergo appendectomy at their second date. Second date appendectomy, i.e. the removal of the appendix when acute inflammation relapses within the scar of a previously unhealed perforated appendicitis, is the unwanted child of the nonoperative treatment and a new challenge for both the surgeon and the patient. Between June and July 2016, two patients were readmitted and operated for failure of nonoperative treatment with antibiotics. A video is presented, which focuses on the different anatomic presentation and technical challenges between prompt and second date laparoscopic appendectomy. When proposing nonoperative treatment for acute appendicitis, surgeons should be aware and inform their patients that if the appendix is perforated and an incomplete healing and early recurrence occur, a second date appendectomy could be a more challenging operation compared to a prompt appendectomy.

    Abstract Gallbladder polyp (GP) and stroke share several metabolic disorders as risk factors. We assessed the association between GP and subsequent stroke risk. From 2000 to 2011, patients with GP aged >20 years were identified from the Longitudinal Health Insurance Database 2000. Of the 15,975 examined patients, 12,780 and 3195 were categorized into the non-GP and GP cohorts, respectively. The relative risks of stroke were estimated using the Cox proportional hazard model after adjusting for age, sex, and comorbidities. The overall incidence of stroke was higher in the GP cohort than in the non-GP cohort (6.66 vs 5.20/1000 person-yr), with an incidence rate ratio (IRR) of 1.28 (95% confidence interval [CI] = 1.15–1.42). The risk of stroke was 1.32-fold (95% CI = 1.06–1.63) in patients with GP compared with patients without GP after adjusting for age, sex, income level, urbanization level, occupation and comorbidities of gallstone, alcohol-related illness, diabetes, hyperlipidemia, hypertension, obesity, COPD, coronary heart disease, and asthma. Furthermore, the stroke risk was higher among elderly patients (with 1-yr intervals; adjusted HR [aHR] = 1.06, 95% CI = 1.05–1.07), the male sex (aHR = 1.62, 95% CI = 1.35–1.96), lower income level (aHR = 1.37, 95% CI = 1.02–1.85 for level I; aHR = 1.62, 95% CI = 1.25–2.10 for level II), living in second urbanized areas (aHR = 1.28, 95% CI = 1.00–1.63), alcohol-related illness (aHR = 1.56, 95% CI = 1.07–2.28), diabetes (aHR = 1.78, 95% CI = 1.41–2.24), and hypertension (aHR = 2.74, 95% CI = 2.19–3.42). GP is associated with stroke; however, GP may be less influential than other risk factors are, such as male sex, lower income level, alcohol-related illness, diabetes, and hypertension, on stroke development. Additional studies are required to clarify whether GP is a risk factor for or an epiphenomenon of stroke development. PMID

    To increase healing rate of tympanic membrane (TM) perforations, patching procedure has been commonly conducted. Biocompatible, biodegradable patching materials which is not limited across cultures is needed. The authors evaluated the effectiveness of novel transparent duck's feet collagen film (DCF) patch in acute traumatic TM perforation. This procedure was compared with spontaneous healing and paper patching. Cell proliferation features were observed in paper and DCF patches. Forty-eight TMs of 24 rats were used for animal experiment, perforations were made on each TMs, and divided into three groups according to treatment modality. Sixteen were spontaneously healed, 16 were paper patched and 16 were DCF patched. The gross and histological healing results were analyzed. Both paper and DCF patch showed no cytotoxicity, but cell proliferations were more active in DCF than paper in early stage. In animal study, the healing of TM perforations were completed within 14 days in all three groups, but found to be faster in DCF patch group than paper patch or spontaneous healing group. The DCF patches were transparent and size of DCF patches were gradually decreased, so there were no need to remove the DCF patches to check the wound status or after the completion of healing. According to this result, authors concluded that DCF patch is transparent, biocompatible and biodegradable material, and can induce fast healing in acute traumatic TM perforations.

    Perforation of jejunal diverticulum is a rare complication. Here, we report a case of jejunal diverticulum penetration with surrounding ectopic pancreas. An 83-year-old female patient was admitted to our department with acute onset of severe abdominal pain lasting for half a day. Abdominal computed tomography showed outpouching of the small intestine that contained air/fluid, with multiple surrounding air bubbles in the mesentery of the small intestine. She was diagnosed with penetration of the small intestine, and an emergency laparotomy was indicated. The penetrated jejunal diverticulum was identified ~20-cm distal to the ligament of Treitz. Partial resection of the jejunum was performed, and her postoperative course was uneventful. The pathological findings confirmed diverticulum penetration into the mesentery and severe inflammation at the site, with surrounding ectopic pancreas. Furthermore, the pancreatic ducts were opened through the penetrated diverticulum. This rare case shows that the ectopic pancreas might have caused penetration of jejunal diverticulum owing to the pancreatic duct opening through the diverticulum.

  9. Progesterone inhibits gallbladder motility through multiple signaling pathways.

    Progesterone (P) has an inhibitory effect on the contractility of gastrointestinal smooth muscle, including the gallbladder. Since P levels are elevated during pregnancy, a biliary stasis may develop during pregnancy that is characterized by an increase in the fasting and residual volumes and by a decrease in emptying capacity. This study investigates the effect of P and two metabolites on contraction in guinea pig gallbladder strips. P induced a concentration-dependent relaxation in guinea pig gallbladder strips precontracted with cholecystokinin octapeptide (CCK). Pretreatment of gallbladder strips with P (50 microM) also reduced the amount of CCK-induced tension. Nifedipine (1 microM) produced a similar effect. Pretreatment of the strips with PKA inhibitor 14--22 amide myristolated (180 nM) or the PKG inhibitor KT5823 (1.2 microM) either separately or in combination significantly reduced the amount of P-induced relaxation. Rp-cAMPs (0.1mM) or H-89 (10 microM) separately or in combination significantly reduced the P-effect; however, the combination of agents produced the largest reduction. Genistein (1 microM), an inhibitor of protein tyrosine kinases, significantly (p<0.01) reduced the amount of P-induced relaxation. The use of strontium in the Kreb's solution as a substitute for Ca(2+) significantly (p<0.01) reduced the amount of CCK-induced tension. Pretreatment of the strips with 2-APB (26 microM), an inhibitor of IP(3,) induced Ca(2+) release, produced a significant (p<0.01) reduction in P-induced relaxation. We conclude that P inhibits gallbladder motility rapidly by nongenomic actions of the hormone. Several pathways that include tyrosine kinase and PKA/cAMP activity may mediate this effect.

    Thus far, there have been tries of detection of disease using fluorescent materials. We introduce the chlorophyll derivatives from food plants, which have longer-wavelength emissions (at >650 nm) than those of fluorescence of tissues and organs, for detection of bowel perforation. To figure out the possibility of fluorescence spectroscopy as a monitoring sensor of bowel perforation, fluorescence from organs of rodent models, intestinal and peritoneal fluids of rodent models and human were analyzed. In IVIS fluorescence image of rodent abdominal organ, visualization of perforated area only was possible when threshold of image is extremely finely controlled. Generally, both perforated area of bowel and normal bowel which filled with large amount of chlorophyll derivatives were visualized with fluorescence. The fluorescence from chlorophyll derivatives penetrated through the normal bowel wall makes difficult to distinguish perforation area from normal bowel with direct visualization of fluorescence. However, intestinal fluids containing chlorophyll derivatives from food contents can leak from perforation sites in situation of bowel perforation. It may show brighter and longer-wavelength regime emissions of chlorophyll derivatives than those of pure peritoneal fluid or bioorgans. Peritoneal fluid mixed with intestinal fluids show much brighter emissions in longer wavelength (at>650 nm) than those of pure peritoneal fluid. In addition, irrigation fluid, which is used for the cleansing of organ and peritoneal cavity, made of mixed intestinal and peritoneal fluid diluted with physiologic saline also can be monitored bowel perforation during surgery.

    Objectives This study was conducted to assess the management of incidental gallbladder cancer and indeterminate gallbladder lesions. Its secondary aim referred to the devising of a management pathway for these patients. Methods Patients referred with incidental gallbladder cancer and indeterminate gallbladder lesions during 2002–2011 were identified from a prospectively maintained database. Collated data included operative findings, histopathological data and survival outcomes. Results The study included a total of 104 patients, 40 of whom had incidental gallbladder cancer following cholecystectomy. In this group, the index cholecystectomy was considered curative (T-is/T1a stage) in three patients; 11 patients underwent further resection, and 26 patients were inoperable. One-, 3- and 5-year overall survival rates were 91.1%, 91.0% and 60.7%, respectively, in patients who underwent re-resection. Of the 64 patients with indeterminate gallbladder lesions, 54 patients underwent modified radical cholecystectomy. Seven patients were found to have gallbladder cancer. One-, 3- and 5-year overall survival rates were 85.9%, 43.1% and 42.8%, respectively. Five-year overall survival in patients treated with surgery for gallbladder cancer was 59.9%. Conclusions The majority of patients with incidental gallbladder cancer were not amenable to further potentially curative resection. The radiological suspicion of gallbladder cancer should lead to prompt referral to a tertiary hepatobiliary unit for further management. PMID:24279377

    Primary carcinoid tumor of the gallbladder is rare and comprises less than 1% of all carcinoid tumors. Preoperative diagnosis of carcinoid tumor of the gallbladder is difficult. The imageology findings are similar to those in other gallbladder cancers. A 46-year-old woman was hospitalized with a preoperative diagnosis of gallbladder carcinoma, The patient was referred for surgical opinion and laparotomy was subsequently performed. A 4 x 5 cm mass was found within the gallbladder, located on the free surface of the body and fundus of the gallbladder. Neither metastases nor direct invasion to the liver was found. The entire mass and gallbladder were excised and intact. Histologically, the tumor consisted of small oval cells with round-to-oval neclei and tumor cells formed small nodular, trabeculare and acinar structures. The tumor showed moderate pleomorphism with scattered mitotic figures, but no definite evidence of vascular permeation, perineural invasion or lymphatic permeation was seen. The tumor cells invaded the mucosa extensively, and some penetrated the muscular layer but not through the serosa of the gallbladder into the liver. Immunohistochemical studies revealed strong positive reaction for chromogranin A and NSE. This lesion was proved to be a primary carcinoid tumor of the gallbladder. A brief review of literature, clinical feature, pathology and treatment of this rare disease was discussed. Primary carcinoid tumor of the gallbladder is uncommon. The definite diagnosis is often made on histopathological results after surgery.

    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 intestine 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.

    In arid and semiarid regions of northwestern China, where evaporation exceeds precipitation, perforated plastic mulches are widely used to decrease soil water evaporation. To determine the effects of various perforated plastic mulches on soil water evaporation after irrigation, a soil column experiment was conducted, which consisted of six mulches with different perforated rates and four levels of irrigation, and the soil water evaporation from each soil column was measured. The results showed that with 100% perforated mulch, the cumulative evaporation was 2.8-48.5 times higher than that of the control, and increased with increasing irrigation amount. There was a linear relationship between cumulative evaporation and time, which followed the Gardner's theory of bare soil evaporation. A three-factor (evaporation time, perforated rate and irrigation amount) function of cumulative evaporation and the functions of relative cumulative evaporation and cumulative evaporation per unit hole area film were established, which fitted the observed data very well.

The pectoralis major musculocutaneous flap is a proven "workhorse" flap, especially for head and neck reconstruction. Yet, the corresponding thoracoacromial artery muscle perforator flap has been relatively overlooked, with few clinical experiences reported, presumably because of the highly variable and diminutive perforators emanating from this source vessel. However, in certain circumstances, this can be another alternative as a local muscle perforator flap for the transfer of chest skin to adjacent defects. Two clinical examples using the island thoracoacromial artery perforator flap prove that this can sometimes be a viable option also for head and neck reconstruction.

    The application of extreme overbalance perforating, by Oryx Energy Co., is consistently outperforming the unpredictable, tubing-conveyed, underbalance perforating method which is generally accepted as the industry standard. Successful results reported from more than 60 Oryx Energy wells, applying this technology, support this claim. Oryx began this project in 1990 to address the less-than-predictable performance of underbalanced perforating. The goal was to improve the initial completion efficiency, translating it into higher profits resulting from earlier product sales. This article presents the concept, mechanics, procedures, potential applications and results of perforating using overpressured well bores. The procedure can also be used in wells with existing perforations if an overpressured surge is used. This article highlights some of the case histories that have used these techniques.

    A variety of corneal pathology can lead to corneal ulcers and perforations. A deep corneal ulcer may need surgical treatment to allow good volume restoration and reepithelisation. Corneal perforation must be sealed and when the perforation is large, the task of repairing the defect can be underwhelming. The elegant solution is the corneal transplant, but this is not always readily available, especially in undeveloped countries. We present here two cases with different solutions to seal the perforated cornea: the first one has a large peripheral defect and it is successfully sealed with scleral patch and the second one is central with small perforation and is successfully sealed with multilayered amniotic membrane. Both cases are followed for over 12 months and demonstrate good corneal restoration (both on clinical examination and corneal topography). Sclera and amniotic membrane can be used to seal corneal defects when corneal transplant is not readily available.
