    The files of patients with acute cholecystitis from two large university hospitals from the years 1978-1985 were employed to find the cases with acute gallbladder perforation for this study. Only those patients (n = 9) were selected for the analysis of sonographic signs of acute gallbladder perforation who had less than 48 hours of symptoms before sonography, and were operated upon within 24 hours of the sonography. Patients (n = 10) with non-complicated acute cholecystitis and identical in regard to the duration of the symptoms and the timing of the sonography and the operation formed a control group. The sonographic findings in patients with gallbladder perforation were pericholecystic fluid collections, free peritoneal fluid, disappearance of the gallbladder wall echoes, focal highly echogenic areas with acoustic shadows in the gallbladder, and an inhomogeneous, generally echo-poor gallbladder wall.

    Gallstone disease is common. However, a proportion of patients are asymptomatic and remain undiagnosed until the occurrence of complications. Common complications include acute cholecystitis, biliary obstruction, acute pancreatitis and cholangitis. Severe complications include gallbladder perforation, Mirizzi syndrome and fistula formation are usually associated with significant morbidity and mortality. We report a case of asymptomatic spotaneous gallbladder perforation due to acute cholecystitis. PMID:24914424

    Acute gallbladder perforation is an infrequent, although not uncommon, complication of cholecystitis. It is rarely diagnosed preoperatively and the delay in making the definitive diagnosis usually accounts for the increased incidence of morbidity and mortality associated with this complication. A case of a 92-year-old patient in whom acute gallbladder perforation was suspected peroperatively at ultrasonography of the abdomen and confirmed by technetium-99m disofenin radionuclide biliary scan is reported.

    An 86-year-old woman, 4 days post-operative following a right-sided Austin-Moore arthroplasty, reported abdominal pain around a known umbilical hernia and became increasingly confused. A diagnosis of incarcerated umbilical hernia was made. At surgery, on entering the peritoneal cavity, bile was immediately noted. The operation was converted to a laparotomy and a perforation was noted in the gallbladder. An open cholecystectomy was performed. Macroscopically the gallbladder was perforated in multiple places, was thin walled and did not contain gallstones. This case demonstrates the difficulty in diagnosing an apparently spontaneous gallbladder perforation in a cognitively frail patient. PMID:25293685

    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

    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.

  8. Laparoscopic cholecystectomy for traumatic gallbladder perforation

    PubMed Central

    Hamilton, C; Carmichael, SP; Bernard, AC

    2012-01-01

    In trauma, laparoscopic surgery is commonly utilized as a diagnostic rather than therapeutic measure (1). Its use is often negated because of exigency or limitations in visibility due to haemorrhage. In the present case, a 35-year-old male was involved in a motor vehicle collision and arrived haemodynamically stable with abdominal pain. Abdominal CT revealed liver laceration and active contrast extravasation near the gallbladder fossa. Although angiography with embolization would normally be used, exploratory laparoscopy was performed because of concern for gallbladder injury. The gallbladder was found to be perforated and nearly completely avulsed from the fossa. Laparoscopic cholecystectomy was performed and the patient recovered uneventfully. Gallbladder perforation after trauma is typically an incidental finding during operation for haemorrhagic shock or other indication. Early diagnosis and swift surgical intervention are required, usually via laparotomy. However, when diagnosed preoperatively in the stable trauma victim, gallbladder perforation can be treated successfully with laparoscopy. PMID:24960682

    Acute biliary tract disease is a common condition in adults. Apart from bile duct perforation, spontaneous perforation of the gallbladder itself is very rare in all age groups; to date, all recorded cases are secondary to coexistent disease. We present the case report of a 60-year-old adult having an idiopathic gallbladder perforation. In our case, an unusual presentation was situs inversus totalis and fundal gas shadow was considered as free air under the right dome of the diaphragm by mistake. The patient underwent laparotomy and emergency cholecystectomy was performed in the perforated gallbladder. To date, no case has been described in the literature.

    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

    Normal gallbladder scintigraphy occurs in 2 to 5% of reported patients with acute cholecystitis. Gallbladder visualization is found in patients with acalculous cholecystitis and in those with recent relief of cystic duct obstruction but persistence of inflammation. A patient is reported who had clinical and pathologic findings of acute cholecystitis but normal gallbladder visualization. This reemphasizes that the diagnosis of acute cholecystitis cannot be excluded by normal gallbladder scintigraphy.

    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.

    Gallbladder perforation is an unusual condition with a high mortality rate. Early detection with prompt surgical intervention can increase the survival rate. Hepatobiliary imaging using Technetium-99m-labeled iminodiacetic acid has been used for the diagnosis of gallbladder perforation. However, the results vary and are somewhat confusing. The authors report a case of gallbladder perforation with hepatobiliary imaging and an unusual gallium image; review the literature; and propose a classification of three different imaging patterns: (1) visualization of the gallbladder with bile leakage, (2) nonvisualization of the gallbladder with a photopenic fluid collection, and (3) nonvisualization of the gallbladder with bile leakage. These patterns may provide pathophysiologic information for the surgeon. 27 references.

    Acute cholecystitis is an inflammatory disease of the gallbladder. Inflammation often remains in the gallbladder, but some patients may take a fatal course with exacerbation of inflammation. Although laparoscopic cholecystectomy is recommended for moderate and severe acute cystitis, sometimes cholecystectomy is impossible in elder patients. Because many elder patients have bad general conditions, cholecystectomy should not be performed. Such patients are generally treated by percutaneous transhepatic gallbladder drainage (PTGBD), but PTGBD has the risk of intra-abdominal bleeding. In previous reports, endoscopic gallbladder stenting (EGBS) has been shown to be an effective strategy in cirrhosis patients with symptomatic cholelithiasis as a bridge to transplantation. Recent studies on EGBS have demonstrated an effective long-term management of acute cholecystitis in elderly patients who are poor surgical candidates. Here, we reviewed EGBS for the management of acute cholecystitis.

    A 65-year-old man with chronic hepatitis C and no history of alcohol abuse was admitted to our liver unit for the recent development of massive ascites and presumed hepatorenal syndrome. In the preceding two weeks, he had received medical treatment for acute pancreatitis and cholecystitis. Abdominal paracentesis demonstrated a cloudy, orange peritoneal fluid, with total protein concentration 3.6 g/dl, serum-ascites albumin gradient 1.0 g/dl, and ratios of ascites-serum bilirubin and amylase approximately 8:1. Diagnostic imaging demonstrated no pancreatic pseudocysts. Ten days later, at laparotomy, acalculous perforation of the gallbladder was identified. After cholecystectomy, amylase concentration in the ascitic fluid dropped within a few days to 40% of serum values; ascites disappeared within a few weeks. We conclude that in the presence of a perforated gallbladder, pancreatobiliary reflux was responsible for this unusual combination of choleperitoneum and pancreatic ascites, which we propose to call pancreatobiliary ascites.

    A 77-year-old man with Alzheimer's disease was admitted to a rural hospital in June 2012 and an acute cholecistytis was first diagnosed. Surgery was not considered as a possible option due to the critical condition of the patient and his severe comorbidities. After 2 days of broad-spectrum antibiotics, the patient worsened and developed severe sepsis. A gallbladder perforation with intrahepatic abscess formation was diagnosed on ultrasonography (US) and abdominal CT scan. The patient underwent percutaneous US-guided gallbladder drainage with resolution of the sepsis and rapid clinical improvement. After 1 month, the drainage was removed and the patient was discharged. He survived in good condition for 18 months and he passed away from pneumonitis in December 2013. This case shows that in a case of acute cholecystitis with gallbladder perforation, percutaneous gallbladder drainage can be a lifesaving procedure in elderly patients with severe comorbidities (including Alzheimer's disease) who are not candidates for elective surgery.

    Gallbladder (GB) perforation is a very rare posttraumatic abdominal injury. It is potentially life-threatening, and good outcome requires early diagnosis. We present a case of isolated posttraumatic GB perforation in which the precise sonographic (US) diagnosis led us to apply proper management. Color Doppler US showed a clear to-and-fro flow signal passing through the perforation site, and contrast-enhanced US confirmed the presence of a small defect in the GB wall. When examining posttraumatic patients, the possibility of GB perforation must be kept in mind. Color Doppler US and contrast-enhanced US are the examinations of choice to detect the perforation site and show bile movement through the perforation.

    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

    A 92-year-old woman presented to the emergency department with a 2-week history of worsening right-sided abdominal pain. On examination she had right mid-abdominal tenderness. Laboratory studies demonstrated leukocytosis with normal liver function tests. A CT of the abdomen was remarkable for a large fluid collection in the right abdomen and no discernible gallbladder in the gallbladder fossa. An ultrasound confirmed the suspicion of a distended, floating gallbladder. The patient was taken to the operating room for laparoscopic cholecystectomy. The gallbladder was found to have volvulised in a counter -clockwise manner around its pedicle, with gross necrosis of the gallbladder. She underwent laparoscopic cholecystectomy. Pathological examination revealed acute necrotising calculus cholecystitis.

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.

  4. Mechanisms for acute corneal hydrops and perforation.

    PubMed

    McMonnies, Charles W

    2014-07-01

    Acute corneal hydrops (ACH) and perforation in corneal thinning diseases are the consequences of exposure to distending intraocular pressure (IOP) forces that are in excess of corneal resistance to them. Apart from thinning, resistance to these forces may be reduced by disease-related tissue changes, such as corneal scarring, which could lower resistance to IOP. Eye rubbing trauma has sometimes been found to be associated with ACH and perforation. This association is not surprising given that the combination of rubbing-related mechanical tissue trauma and the associated increased distending stress of higher IOP seem likely to increase the risk of complications. Many cases of ACH and perforation are described as spontaneous, but this classification may be the consequence of not considering the multiple potential mechanisms for IOP elevation such as coughing, sneezing, nose blowing, and sneeze suppression in addition to those related to eye rubbing/wiping/massaging/touching as well as changes in body orientation, strenuous exercise, and wearing swimming goggles for example. Classification of ACH or perforation as spontaneous may lead patients to assume that nothing can be done to avoid these complications. Patients with corneal thinning diseases who are counseled regarding the potential precipitating mechanisms for IOP elevation will have the opportunity of reducing exposure to them and the risk of the associated complications. In addition, when ACH or perforation occur, faster resolution of edema and wound healing may depend on reducing potentially exacerbating exposures to mechanisms for IOP elevation. PMID:25390550

    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.

    In five of seven patients with acute pancreatitis, Tc-99m HIDA scintigraphy failed to visualize the gallbladder. In all five patients the gallbladder was later found to be normal and in three of them normal filling was obtained at a repeat examination performed after the attack had subsided. Transient nonvisualization of the gallbladder in acute pancreatitis is probably due to disturbed motility of the biliary tree.

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.

    Although non-small cell lung cancer (NSCLC) can metastasize to almost any organ, metastasis to the gallbladder with significant clinical manifestation is relatively rare. Here, we report a case of gallbladder metastasis of NSCLC presenting as acute cholecystitis. A 79-year-old man presented with pain in the right upper quadrant and fever. A computed tomography (CT) scan of the chest and abdomen showed a cavitary mass in the right lower lobe of the lung and irregular wall thickening of the gallbladder. Open cholecystectomy and needle biopsy of the lung mass were performed. Histological examination of the gallbladder revealed a moderately-differentiated squamous cell carcinoma displaying the same morphology as the lung mass assessed by needle biopsy. Subsequent immunohistochemical examination of the gallbladder and lung tissue showed that the tumor cells were positive for P63 but negative for cytokeratin 7, cytokeratin 20 and thyroid transcription factor-1. A second primary tumor of the gallbladder was excluded by immunohistochemical methods, and the final pathological diagnosis was gallbladder metastasis of NSCLC. Although the incidence is extremely rare, acute cholecystitis can occur in association with lung cancer metastasis to the gallbladder. PMID:23358590

    The gallbladder is often colonized by Salmonella during typhoid fever, yet little is known about bacterial pathogenesis in this organ. With use of a mouse model of acute typhoid fever, we demonstrate that Salmonella infect gallbladder epithelial cells in vivo. Bacteria in the gallbladder showed a unique behavior as they replicated within gallbladder epithelial cells and remained confined to those cells without translocating to the mucosa. Infected gallbladders showed histopathological damage characterized by destruction of the epithelium and massive infiltration of neutrophils, accompanied by a local increase of proinflammatory cytokines. Damage was determined by the ability of Salmonella to invade gallbladder epithelial cells and was independent of high numbers of replication-competent, although invasion-deficient, bacteria in the lumen. Our results establish gallbladder epithelial cells as a novel niche for in vivo replication of Salmonella and reveal the involvement of these cells in the pathogenesis of Salmonella in the gallbladder during the course of acute typhoid fever.

    A male Pickwickian syndrome patient was admitted to the hospital with sudden onset of abdominal pain. Physical examination was equivocal. Due to patient's ileus and morbid obesity (weight 450 lb), neither TCT scan nor ultrasound was possible. A Tc-99m PIPIDA hepatobiliary imaging study revealed intraperitoneal leakage of radioactive bile with collection of the activity in both abdominal gutters, indicating gallbladder rupture. Prompt surgery confirmed the diagnosis.

    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

    With the evolution of the linear echoendoscope and the improved ability to direct a needle within the field of interest, the therapeutic potential of endoscopic ultrasonography (EUS) has greatly expanded. Endoscopic ultrasonography-guided transmural gallbladder drainage (EUS-GBD) may be the next frontier for therapeutic EUS. Since EUS-GBD was first described in 2007, recent reports have suggested it as an alternative to external gallbladder drainage for acute cholecystitis. EUS-GBD includes EUS-guided transmural nasogallbladder drainage, EUS-guided gallbladder aspiration, and EUS-guided transmural gallbladder stenting. Indications for the EUS-GBD technique as currently practiced, including equipment, technical details, complications, and efficacy are herein reviewed.

    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.

    Gallbladder hyperemia in acute cholecystitis (AC) has been described pathologically and angiographically. The authors' purpose is to evaluate the use of scintiangiography for the detection of this hypernia as a supporting sign of AC. Ten mCi of Tc 99m disofenin were injected by bolus technique in 64 patients with suspected AC. Sequential 3 second images were obtained with a 500K blood pool image at one minute. Routine images to 60 minutes were performed followed by delayed views. The scintiangiogram was positive if there was focal increased activity in the gallbladder fossa greater than liver and separate from right kidney during the preportal arterial phase. The location of the gallbladder fossa was determined by superimposition with the early hepatocyte phase. AC was confirmed surgically and normals confirmed clinically. Increased flow to the gallbladder fossa was demonstrated in 23/32 cases of AC and in 2/33 normals (72% sensitivity, 94% specificity). Accuracy is 54/65 (83%). Positive predictive value is 23/25 (92%). All patients with both a positive scintiangiogram and cholescintigram had AC, while 3 with pericholecystic abscess and false negative cholescintigram had positive scintiangiograms. Increased perfusion to the gallbladder fossa during scintiangiography is a sign of AC. This along with gallbladder nonvisualization by cholescintigraphy was able to predict AC in 100% of cases where both findings occurred. Scintiangiography may help select our patients with a very high likelihood of AC and may potentially shorten chole-scintigraphy examinations.

    Torsion of the gallbladder is rare. However, the surgeon should be aware of it and that unusual presentations in the elderly make early diagnosis very difficult. A 100-year-old white female presented with right-sided abdominal pain and was found to have acute torsion of the gallbladder. The clinical picture, diagnostic tests, and operative findings are outlined. Serial evaluations of the patient's condition and a high index of suspicion are essential elements for prompt recognition and early surgical management. PMID:3999156

    2015-01-01

    Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been introduced as an alternative to percutaneous transhepatic gallbladder drainage for the treatment of acute cholecystitis in non-surgical candidates. A systematic review of the English language literature through PubMed search until June 2014 was conducted. One hundred and fifty-five patients with acute cholecystitis treated with EUS-GBD in eight studies and 12 case reports, and two patients with EUS-GBD for other causes were identified. Overall, technical success was obtained in 153 patients (97.45%) and clinical success in 150 (99.34%) patients with acute cholecystitis. Adverse events developed in less than 8% of patients, all of them managed conservatively. EUS-GBD has been performed with plastic stents, nasobiliary drainage tubes, standard or modified tubular self-expandable metal stents (SEMS) and lumen-apposing metal stents (LAMS) by different authors with apparently similar outcomes. No comparison studies between stent types for EUS-GBD have been reported. EUS-GBD is a promising novel alternative intervention for the treatment of acute cholecystitis in high surgical risk patients. Feasibility, safety and efficacy in published studies from expert centers are very high compared to currently available alternatives. Further studies are needed to establish the safety and long-term outcomes of this procedure in other practice settings before EUS-GBD can be widely disseminated.

  17. Age, Predisposing Diseases, and Ultrasonographic Findings in Determining Clinical Outcome of Acute Acalculous Inflammatory Gallbladder Diseases in Children

    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.

  19. Amylase: creatinine clearance ratio and urinary excretion of lysozyme in acute pancreatitis and acute duodenal perforation.

    Berger, G M; Cowlin, J; Turner, T J

    1976-09-18

    The amylase:creatinine clearance ratio in patients suffering from acute pancreatitis or acute duodenal perforation was higher than normal in both groups of patients. These findings cast doubt on the value of this parameter as a specific index of acute pancreatitis. The mechanism or mechanisms underlying the increased amylase excretion have not been determined. However, the markedly elevated urinary excretion of lysozyme observed in some patients suggests, by analogy, that diminished tubular reabsorption of amylase may contribute towards the elevated amylase:creatinine ratio.

    Acute abdomen during pregnancy is a medico-surgical emergency demanding concerted, synchronized specialties approach of obstetrician, surgeon and gastroenterologist. Duodenal perforation is one of the rarer causes of acute abdomen in pregnancy. Here, we report a case of duodenal perforation with peritonitis in third trimester of pregnancy requiring surgical management. Our aim of reporting this case is to stress the physicians to keep the differential of duodenal perforation also in mind while dealing with cases of acute abdomen in pregnancy and to proceed with multidisciplinary approach for better feto-maternal outcome.

    Findings on cholescintigraphy in gallbladder carcinoma are described in five patients. Four patients presenting with acute cholecystitis had nonvisualization of the gallbladder with normal hepatoenteric transit time. One of these had a large portal mass and two had liver metastasis as additional findings. The fifth patient was jaundiced, and showed absence of bowel activity compatible with total biliary obstruction. Both the clinical and scintigraphic findings in gallbladder carcinoma are difficult to separate from findings in cholelithiasis and cholecystitis.

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.

    Among the colorectal cancers, the incidence of colon cancer has obviously increased. As a result, the actual incidence of colon cancer has exceeded that of rectal cancer, which dramatically changed the long-existing epidemiological profile. The acute complications of colon cancer include bleeding, obstruction, and perforation, which were among the common acute abdominal surgical conditions. The rapid and accurate diagnosis of these acute complications was very important, and laparoscopic techniques can be applied in abdominal surgery for management of the complications. PMID:25035661

    Duplication of the gallbladder is a rare congenital anomaly of the biliary system. In this article, two cases of gallbladder duplication are presented. The first case is a patient with double gallbladder and concomitant choledocholithiasis. The probable diagnosis of double gallbladder was made preoperatively by computed tomography. The patient underwent a successful open cholecystectomy and common bile duct exploration. In the second case, two cystic formations in the place of gallbladder are demonstrated with ultrasound scan in a woman with acute cholecystitis. At surgery, two gallbladders were found. A brief review of epidemiology and anatomy of double gallbladder is included, along with a discussion of the difficulties in diagnosis and treatment of this condition.

    2016-02-01

    Colonic diverticulitis is a common condition in the western population. Complicated diverticulitis is defined as the presence of extraluminal air or abscess, peritonitis, colon occlusion, or fistulas. Multidetector row computed tomography (MDCT) is the modality of choice for the diagnosis and the staging of diverticulitis and its complications, which enables performing an accurate differential diagnosis and addressing the patients to a correct management. MDCT is accurate in diagnosing the site of perforation in approximately 85% of cases, by the detection of direct signs (focal bowel wall discontinuity, extraluminal gas, and extraluminal enteric contrast) and indirect signs, which are represented by segmental bowel wall thickening, abnormal bowel wall enhancement, perivisceral fat stranding of fluid, and abscess. MDCT is accurate in the differentiation from complicated colon diverticulitis and colon cancer, often with a similar imaging. The computed tomography-guided classification is recommended to discriminate patients with mild diverticulitis, generally treated with antibiotics, from those with severe diverticulitis with a large abscess, which may be drained with a percutaneous approach.

    Hyponatremia and its related comorbidities remain a concern after traditional transurethral resection of the prostrate (TURP). Photoselective vaporization of the prostate (PVP) laser coagulation therapy is a new, relatively bloodless procedure for treatment of benign prostatic hyperplasia (BPH). Perceived benefits with PVP laser TURP include excellent visualization of the operative field during urethral prostatic tissue vaporization and the reduced incidence of laser penetration through the prostatic capsular fibers once the capsule is reached. Theoretically, this would provide a low risk method of perforation during laser TURP. After literature review, we report this as the first case of laser bladder perforation as a complication arising from PVP therapy. This case report discusses the management of acute hyponatremic induced rhabdomyolysis with acute renal failure (ARF) and the recommendation to use sodium chloride vs. sterile water for bladder irrigation during PVP TURP procedures.

    Diagnosis and treatment of common conditions in morbidly obese patients still pose a challenge to physicians and surgeons. Sometimes too much reliance is put on investigations that can lead to a misdiagnosis. This case demonstrates an obese woman admitted under the medical team with a presumed diagnosis of pneumonia, who was later found to have an acute abdomen and raised amylase, which led to an assumed diagnosis of pancreatitis. She died within 24 h of admission and post mortem confirmed the cause of death as systemic sepsis due to perforated appendicitis, with no evidence of pancreatitis. Significantly elevated serum amylase level may occur in non-pancreatitic acute abdomen.

    Diverticulum of the caecum is a rare lesion. From a clinical point of view, the inflammation it causes can mimic symptoms of acute appendicitis, causing difficulties in diagnosis and thus prescription of appropriate treatment. It is almost impossible to differentiate this disease from acute appendicitis through physical examination alone, and radiological imaging may also prove insufficient. For this reason, it is common to perioperatively diagnose diverticula of the caecum. Two cases of patients who underwent surgery for perforated caecal diverticula are presently described.

    Background Intrahepatic gallbladder perforation with chronic liver abscess formation was anecdotically reported in the literature. The aim of this work is to report a case of intrahepatic gallbladder perforation and its atypical clinical presentation. Case presentation A 62-year-old male patient came to our observation; his medical history showed intermittent fever up to 39-40°C of about 2 weeks and anorexia, with an overall weight loss of about 12 Kg. Physical examination of the abdomen was negative. An ultrasound of the liver and an abdominal CT angiogram detected a disomogeneous hypoechoic-hypodense area in the 5th segment of the liver. Differential diagnosis between hepatic abscess or gallbladder cancer remained open. A surgical exploration was planned. After laparoscopic exploration, a conversion to open procedure with an atypical resection of the 5th hepatic segment was performed. Histologic examination of the specimen showed an intrahepatic chronic perforation of the gallbladder with intrahepatic abscess. Conclusion To the best of our knowledge, 18 cases have been reported in the literature as a Niemeier type I perforation. Clinical presentation, even in its extreme rarity, is more often acute. Differential diagnosis between gallbladder cancer versus liver abscess remains controversial. Open approach is mandatory in such cases. PMID:24468118

While presence of infiltrate of a small size and favorable course under the influence of conservative therapy it is necessary to follow an expectant tactics up to complete dissolving of the infiltrate with a consequent obligate operative treatment in a "cold" period of the disease. Not rarely the infiltrate is transformed into a gallbladder oedema, what demands performance of a deferred operation. In a deep destructive process a gallbladder empyema may occur or paravesical abscess formated, what demands performance of urgent operative intervention.

    This article reviews a spectrum of gallbladder conditions that are either uncommon or represent unusual manifestations of common diseases. These conditions are divided into four major categories: (a) congenital anomalies and normal variants including duplication, ectopia, and lymphangioma; (b) inflammatory processes and stone-related diseases and complications including adenomyomatosis, emphysematous cholecystitis, xanthogranulomatous cholecystitis, gangrenous and hemorrhagic cholecystitis, perforation, gallstone ileus, and Bouveret and Mirizzi syndromes; (c) gallbladder neoplasms including adenocarcinoma with associated porcelain gallbladder, squamous cell carcinoma, lymphoma, melanoma, and neurofibroma. A thorough understanding of the imaging characteristics of each condition can help the radiologist to make a timely and accurate diagnosis, thus avoiding potentially harmful delays in patient management and decreasing morbidity and mortality rates.

    Endometriosis is a quite common pathology, however, intestinal endometriosis is a rare condition, which typically occurs with chronic symptoms. Its acute presentation is very infrequent. We herein report four cases of intestinal endometriosis, in which the clinical debut occurred acutely: two as an acute small bowel obstruction and two as a small bowel perforation. None of the cases had a preoperative diagnosis of endometriosis. The interest of these cases lies in this exceptional form of presentation, such as a surgical acute abdomen. Therefore, intestinal endometriosis should be taken into account in the differential diagnosis of an acute obstructive or perforative process of the small or large bowel. PMID:27629952

    Acute otitis media (AOM) is an inflammatory response to microbes in the middle ear, sometimes associated with rupture of the tympanic membrane. Human leukocytes produce different patterns of inflammatory mediators in vitro when stimulated with Gram-positive and Gram-negative bacteria, respectively. Here, we investigated the cytokine and prostaglandin E2 (PGE2) responses in middle ear fluids (MEFs) from children with spontaneously perforated AOM, and related the mediator levels to the presence of pathogens detected by culture (live) or PCR (live or dead). Furthermore, the in vivo cytokine pattern was compared with that induced in leukocytes stimulated by dead bacteria in vitro. MEFs with culturable pathogenic bacteria contained more interleukin (IL)-1β (median: 110 μg/L vs. <7.5 μg/L), tumour necrosis factor (TNF) (6.3 μg/L vs. <2.5 μg/L), IL-8 (410 μg/L vs. 38 μg/L) and IL-10 (0.48 μg/L vs. <0.30 μg/L) than culture-negative fluids, irrespective of PCR findings. IL-6 and PGE2 were equally abundant (69-110 μg/L) in effusions with live, dead or undetectable bacteria. Cytokine levels were unrelated to bacterial species and to the presence or absence of virus. Similar levels of TNF and IL-6 as found in the MEFs were obtained by in vitro stimulation of leukocytes, whereas 11 times more IL-1β and 3.5 times more IL-8 were produced in vivo, and 22 times more IL-10 was produced in vitro. Vigorous production of proinflammatory cytokines accompanies AOM with membrane rupture, regardless of the causative agent, but the production seems to cease rapidly once the bacteria are killed and fragmented. IL-6 and PGE2, however, remain after bacterial disintegration, and may play a role in the resolution phase.

The main categories of human disease with the Mucorales are sinusitis/rhinocerebral, pulmonary, cutaneous/subcutaneous, gastrointestinal and disseminated disease. Other disease states occur with a much lower frequency and include cystitis, vaginitis; external otitis and allergic disease. We report a diabetic patient with comorbidities, who developed gastric perforation clinically indistinguishable from perforated peptic ulcer due to invasive gastric mucormycosis complicated by spleen infarction.

    The treatment of acute thromboembolic limb ischemia includes well-established surgical thrombectomy procedures and, in recent times, also percutaneous rotational thrombectomy using Straub Rotarex® system. This modality not only enables efficient treatment of such thrombotic occlusion but also in rare cases may imply the risk of perforation of the occluded artery. Herein, we report the case of a perforation of the superficial femoral artery (SFA) in an elderly female patient with thromboembolic limb ischemia. The perforation was successfully treated by implantation of self-expanding nitinol Supera stents and without the need for implantation of a stent graft. PMID:27213074

  12. In vitro modeling of gallbladder-associated Salmonella spp. colonization.

    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.

    Abstract Background For more than a century, appendicectomy has been the treatment of choice for appendicitis. Recent trials have challenged this view. This study assessed the benefits and harms of antibiotic therapy compared with appendicectomy in patients with non‐perforated appendicitis. Methods A comprehensive search was conducted for randomized trials comparing antibiotic therapy with appendicectomy in patients with non‐perforated appendicitis. Key outcomes were analysed using random‐effects meta‐analysis, and the quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results Five studies including 1116 patients reported major complications in 25 (4·9 per cent) of 510 patients in the antibiotic and 41 (8·4 per cent) of 489 in the appendicectomy group: risk difference −2·6 (95 per cent c.i. –6·3 to 1·1) per cent (low‐quality evidence). Minor complications occurred in 11 (2·2 per cent) of 510 and 61 (12·5 per cent) of 489 patients respectively: risk difference −7·2 (−18·1 to 3·8) per cent (very low‐quality evidence). Of 550 patients in the antibiotic group, 47 underwent appendicectomy within 1 month: pooled estimate 8·2 (95 per cent c.i. 5·2 to 11·8) per cent (high‐quality evidence). Within 1 year, appendicitis recurred in 114 of 510 patients in the antibiotic group: pooled estimate 22·6 (15·6 to 30·4) per cent (high‐quality evidence). For every 100 patients with non‐perforated appendicitis, initial antibiotic therapy compared with prompt appendicectomy may result in 92 fewer patients receiving surgery within the first month, and 23 more experiencing recurrent appendicitis within the first year. Conclusion The choice of medical versus surgical management in patients with clearly uncomplicated appendicitis is value‐ and preference‐dependent, suggesting a change in practice towards shared decision‐making is necessary.

    Cholescintigraphic diagnosis of acute cholecystitis requires accurate assessment of gallbladder nonvisualization. Confusion may occur when the gallbladder overlies the duodenal sweep or when labeled bile pools in the duodenum. Gallbladder activity could not be differentiated from duodenal activity in 21 patients. The oral ingestion of 225 ml of water permitted successful differentiation of the gallbladder from the duodenum. In 25 control subjects, it was demonstrated that that volume of water did not have a cholecystokinetic effect.

  15. Biliary sludge: the sluggish gallbladder.

    2003-07-01

    Biliary sludge is a mixture of particulate matter which has precipitated from bile. It generally consists of cholesterol monohydrate crystals, calcium bilirubinate or other calcium salts. In a clinical setting, biliary sludge is almost always an ultrasonographic diagnosis. Although it is less clinically applicable, direct microscopic examination of gallbladder bile is far more sensitive than ultrasonography into sludge detection, and has to be regarded as the diagnostic gold standard. The overall prevalence of sludge in the general population is relatively low. However, several clinical conditions are associated with a particularly high prevalence of biliary sludge, including pregnancy, rapid weight loss, total parenteral nutrition, octreotide therapy, bone marrow or solid organ transplantation. The clinical course of biliary sludge varies, and complete resolution, a waxing and waning course, and progression to gallstones are all possible outcomes. It may cause complications usually associated with gallstones, such as biliary colic, acute cholecystitis, and acute pancreatitis. The main pathogenic mechanism involved in sludge formation is probably gallbladder dismotility, and in selected patients measures aimed to maintain adequate gallbladder contractions has been shown to effectively prevent sludge development.

    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.

    We report a rare case of gallbladder duplication in a young male patient with acute pyocoele in one vesicle and acute cholecystitis with cystadenoma in the other; another unusual feature was the absent or obliterated cystic duct in the proximal vesicle and non-communication with the second vesicle or the biliary system. Ultrasound examination had suggested a septate gallbladder; the diagnosis of dual gallbladder was made per-operatively during separation of the distal moiety which was presumed to be an adherent duodenum initially. Intraoperative cholecystogram confirmed the diagnosis and both gallbladders were removed successfully laparoscopically.A high degree of awareness, detailed preoperative investigations when anomalies are suspected and intraoperative cholangiography are necessary for accurate detailing of the biliary tree to avoid inadvertent damage to the biliary ductal system and overlooking of second or third gallbladder during surgery.

    In five of seven patients with acute pancreatitis, Tc-99m HIDA scintigraphy failed to visualize the gallbladder. In all five patients the gallbladder was later found to be normal and in three of them normal filling was obtained at a repeat examination performed after the attack had subsided. Transient nonvisualization of the gallbladder in acute pancreatitis is probably due to disturbed motility of the biliary tree.

    Prostaglandins have been shown to play a role in gallbladder disease. This study was performed to evaluate prostaglandin E and F production by human gallbladder mucosal cells and muscle tissue from patients undergoing cholecystectomy for acalculous gallbladder disease. These results were compared to values produced by gall bladders removed from patients with no known gallbladder disease. Five patient underwent cholecystectomy for acute and five for chronic acalculous cholecystitis. Gallbladder mucosal cells were separated from muscle wall by submucosal injection of EDTA and shaking in tissue culture media. Prostaglandin levels were measured in mucosal cell and muscle tissue homogenate by radioimmunoassay (ng/mg homogenate protein). Homogenate prostaglandin E concentrations were significantly increased in mucosa and muscle tissue in gall bladders from patients with acute acalculous cholecystitis. Chronic acalculous gallbladder disease was not associated with changes in prostaglandin formation when compared to values produced by gall bladders from asymptomatic patients. Acute acalculous cholecystitis may be a prostaglandin mediated disorder.

    Evaluation of patients with signs and symptoms of biliary tract disease usually includes ultrasound assessment of the gallbladder. Does measurement of the thickness of the gallbladder wall yield any significant information to the clinical surgeon? The records of all my patients undergoing cholecystectomy since 1990 were reviewed. The entire series consists of 401 consecutive patients, in whom 388 procedures were completed laparoscopically, with 14 patients requiring conversion to an open cholecystectomy. Each patient's preoperative evaluation included a gallbladder ultrasound, which included measurement of the diameter of the gallbladder wall. The entire series of cholecystectomies was evaluated according to the ultrasound measured diameter of the gallbladder wall. A thin gallbladder wall was less than 3 mm in diameter. A thick gallbladder wall was 3 mm or greater in diameter. Of the 401 consecutive patients who underwent cholecystectomy for symptomatic gallbladder disease, 86 (21.5%) were removed laparoscopically for acalculous disease. Eleven per cent of patients with acalculous cholecystitis had acute cholecystitis and 89 per cent had chronic cholecystitis. Every patient with either a thin or thick gallbladder wall with acalculous cholecystitis had a successful laparoscopic cholecystectomy. Three-hundred fifteen patients had a laparoscopic cholecystectomy for calculous cholecystitis. In patients with calculous cholecystitis, 28.3 per cent had acute cholecystitis and 71.7 per cent had chronic cholecystitis. The gallbladder wall was found to be greater than 3 mm in 38 per cent of patients with acute calculous cholecystitis and greater than 3 mm in 41 per cent of patients with chronic calculous cholecystitis. One-hundred, forty-two patients, out of a series total of 401, had a gallbladder wall thickness greater than 3 mm by preoperative sonography and 14 of these patients (10%) required conversion to an open cholecystectomy.

    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.

    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.

    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.

Compared with TEE, TTE has a low diagnostic sensitivity in the detection of this complication and, in the presence of hemodynamic instability, multiplane TEE should be performed directly.

    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.

  14. Gallbladder stones: shockwave therapy.

    PubMed

    Sackmann, M

    1992-11-01

    Within the past 7 years, gallbladder lithotripsy by shockwaves has been proven to be a safe and effective non-invasive therapy for selected patients with gallstone disease. While regulatory decisions prevent shockwave therapy from being used more frequently in the USA, the number of patients treated in Europe and Asia is increasing constantly. At our institution, a relatively constant number of about 250 new patients per year have been treated since 1988 (Figure 4). About 20% of patients with gallstones are suitable for shockwave therapy according to present criteria. The rate of evacuation of all fragments is determined by the initial stone number and stone size, the success at stone fragmentation, adjuvant bile acid dissolution therapy, and gallbladder contractility. In contrast to laparoscopic cholecystectomy (Dubois et al, 1989; Perissat et al, 1989; Southern Surgeons Club, 1991), shockwave therapy does not require general anaesthesia. And in contrast to direct contact dissolution therapy of gallbladder stones using MTBE (Thistle et al, 1989), lithotripsy is non-invasive. In the majority of patients, complete fragment disappearance takes several months. Preliminary analyses of the cost-effectiveness of lithotripsy have revealed that lithotripsy, including retreatments and bile acid medication for recurrent stones, costs about as much as open cholecystectomy (Rothschild et al, 1990; Bass et al, 1991). The ideal patient for gallbladder lithotripsy has a single radiolucent stone < or = 20-25 mm in diameter in a functioning gallbladder (Figure 1). In patients with such stones, nearly all studies have confirmed a favourable outcome with rapid clearance of all fragments and a relatively low rate of stone recurrence. For carefully selected patients, extracorporeal shockwave lithotripsy is therefore an attractive non-invasive therapy.

    Obesity has become an epidemic worldwide. It is accompanied by a multitude of medical complications including metabolic syndrome. Obesity may lead to fatty infiltration of multiple internal organs including liver, heart, kidney, and pancreas, causing organ dysfunctions. Fatty infiltration leads to chronic inflammation and tissue damage. Fatty infiltration in the liver results in nonalcoholic fatty liver disease, which is increasingly common nowadays. Recent studies in animals and humans indicate that obesity also is associated with fatty infiltration of gallbladder, resulting in cholecystosteatosis. The increased gallbladder lipids include free fatty acids, phospholipids, and triglycerides. Enhanced inflammation with an increased amount of fat in the gallbladder results in an abnormal wall structure and decreased contractility. In support of this notion, a recent experiment on the effect of Ezetimibe, which is a novel drug that inhibits intestinal fat absorption, on fatty gallbladder disease reveals that Ezetimibe can ameliorate cholecystosteatosis and restore in vivo gallbladder contractility. The proportion of cholecystectomies performed for chronic acalculous cholecystitis has increased significantly over the past two decades. An increase in gallbladder fat, which leads to poor gallbladder emptying and biliary symptoms, may partly explain this phenomenon. Although dietary carbohydrates have been demonstrated to be associated with fatty gallbladder disease, other potential modifiable environmental factors are not clear. The pathogenesis and prognosis of fatty gallbladder disease, including steatocholecystitis, and the relations of fatty gallbladder disease to nonalcoholic fatty liver disease, including steatohepatitis, and other components of metabolic syndrome are largely unknown. More research is needed to answer these questions.

    Various drugs and medications that inhibit or stimulate gallbladder contraction and basal tone in humans are described. Active gallbladder contraction may be achieved using synthetic hormones such as cholecystokinin, caerulein and motilin, cholinomimetic drugs such as bethanecol, prostigmine, and erythromycin due to its motilin-like effect. Furthermore, cisapride and cholestyramine, may have some excitatory activity on the gallbladder muscle. Intravenous amino acids also induce gallbladder contraction through the release of cholecystokinin. Inhibition of gallbladder contraction induced by a meal, or reduction of the basal fasting tone may be achieved by using atropine and other cholinergics, and by inhibitory hormones such as somatostatin, the nitric acid releaser arginine, the calcium channel antagonist nifedipine, and progesterone. Other drugs such as trimebutine, loperamide and ondansetron may negatively affect gallbladder contraction. PMID:12974504

    Perforation peritonitis is the most common surgical emergency encountered by surgeons all over the world as well in India. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counterpart. This study was conducted at Hindu Rao Hospital, Municipal Corporation of Delhi, New Delhi, India, designed to highlight the spectrum of perforation peritonitis in the eastern countries and to improve its outcome. This prospective study included 77 consecutive patients of perforation peritonitis studied in terms of clinical presentations, causes, site of perforation, surgical treatment, postoperative complications, and mortality at Hindu Rao Hospital, Delhi, from March 1, 2011 to December 1, 2011, over a period of 8 months. All patients were resuscitated and underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled. The most common cause of perforation peritonitis noticed in our series was perforated duodenal ulcer (26.4 %) and ileal typhoid perforation (26.4 %), each followed by small bowel tuberculosis (10.3 %) and stomach perforation (9.2 %), perforation due to acute appendicitis (5 %). The highest number of perforations was seen in ileum (39.1 %), duodenum (26.4 %), stomach (11.5 %), appendix (3.5 %), jejunum (4.6 %), and colon (3.5 %). Overall mortality was 13 %. The spectrum of perforation peritonitis in India continuously differs from western countries. The highest number of perforations was noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. The most common cause of perforation peritonitis was perforated duodenal ulcer and small bowel typhoid perforation followed by typhoid perforation. Large bowel perforations and malignant perforations were least common in our setup.

    Gallbladder carcinoma is a relatively rare malignant epithelial neoplasm, arising from gallbladder mucosa. It is the fifth most common gastrointestinal malignancy and the most common biliary tract cancer. Early diagnosis remains difficult, because clinical symptoms are sparse and non-specific, often resulting in advanced stage disease at the time of diagnosis. The most common feature of gallbladder carcinoma on different imaging modalities is focal wall thickening, associated with a large eccentric tumor mass. In this case we report the imaging characteristics of gallbladder carcinoma on ultrasound, MDCT and 18F-FDG PET/CT.

    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.

    The goals of this DOE-sponsored program are to create novel organic thin films that possess well-defined and adjustable molecular pores; i.e. perforated monolayers,'' and to use such film for fabricating composite membranes that have unique permeation characteristics. The specific strategy that has been adopted involves (1) the synthesis of surfactant molecules bearing internal pores, i.e., porous surfactants,'' (2) the assembly of such molecules at an air--water interface, and (3) the stabilization of the resulting assembly via polymerization, before or after transfer to a macroporous support. Research that has been carried out to date has demonstrated the feasibility of using suitably designed calix(n)arene molecules as a basis for constructing perforated monolayers. Specifically, a broad range of calix(n)arenes have been mercurated with mercury trifluoracetate, and used to form polymerized and porous monolayers at the air--water interface. In related studies, p-tert- butylcalix(6)arene has been shown to produce stable monolayers at the air--water interface; removal of the p-tert-butyl groups afford a unique vesicle-forming surfactant, calix(6)arene.

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC.

    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

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

    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]. Results of derivative studies that have also been completed are also described in this report.

    2015-12-09

    Gallbladder mucocoele (GBM) is an abnormal, intraluminal accumulation of inspissated bile and/or mucous within the gallbladder. Older, small- to medium-breed dogs seem to be predisposed, but no sex predilection has been identified. Clinical signs are often non-specific and include vomiting, lethargy, anorexia, abdominal pain, icterus and polyuria-polydipsia. Results of a complete blood count may be unremarkable, but serum biochemistry usually reveals increased liver enzymes. The ultrasonographic appearance is diagnostic and well described in the literature. Surgical intervention for the treatment of GBM remains the therapeutic gold standard, with short- and long-term survival for biliary surgery being 66%. The worst outcome is seen in those dogs requiring cholecystoenterostomy. With GBM becoming an apparently increasingly common cause of extrahepatic biliary disease in canines, it is essential that clinicians become familiar with the current literature pertaining to this condition. Numerous predisposing factors are highlighted in this review article and the role of certain endocrinopathies (e.g. hyperadrenocorticism and hypothyroidism) in the development of GBM is touched upon. Furthermore, the aetiopathogenesis of this disease is discussed with reference to the latest literature. Cholecystectomy remains the treatment of choice, but other options are considered based on a current literature review.

    The computed tomographic CT findings in five patients with acute cholecystitis were analyzed. Common findings included thickening and nodularity of the gallbladder wall, cholelithiasis, and dilatation of the gallbladder lumen. Other more specific findings included poor definition of the gallbladder wall, pericholecystic fluid collections, and gas collections within the gallbladder wall. Most of the CT findings are suggestive but not pathognomonic, and correlation with the clinical, scintigraphic, and sonographic findings is necessary.

    Acalculous cholecystitis is a rare but life-threatening disease, but its pathogenesis is not fully revealed yet. We experienced two acalculous cholecystitis cases associated with aortic dissection. In Case 1, acalculous cholecystitis occurred just after the exacerbation of the aortic dissection. Laparotomy showed necrotized cholecystitis with fresh thrombi formation. Case 2 developed acalculous cholecystitis on the 65th hospital day of aortic dissection. Laparotomy revealed the perforation of the gallbladder. Histological study revealed fibrosis and hemosiderosis in the subserosal layer. The histological findings of these two patients are quite different: Case 1 is acute ischemic and Case 2 is chronic ischemic. While a few cases of acute ischemic cholecystitis have been reported previously, chronic acalculous cholecystitis (CAC) has not been documented. History of aortic dissection could be a risk factor of acute and CAC due to relatively decreased splanchnic blood flow. PMID:26232599

    Major risk factors for gallbladder disease include a sedentary lifestyle and a diet rich in refined sugars. In genetically prone individuals, these two factors lead to an abnormal bile composition, altered gut microflora, and hyperinsulinemia, with resulting gallstone formation. As a large percentage of gallbladder patients have continued digestive complaints following cholecystectomy, the author examines complementary and alternative medicine (CAM) treatments to counteract gallstone formation. Herbal medicine such as turmeric, oregon grape, bupleurum, and coin grass may reduce gallbladder inflammation and relieve liver congestion. Elimination of offending foods, not necessarily 'fatty' foods, is often successful and recommended by many holistic physicians. Regular aerobic exercise has a beneficial effect on hyperinsulinemia, which is often associated with gallbladder disease. Dietary changes that lower plasma insulin levels, such as a change in dietary fats and substitution of unrefined carbohydrates for refined carbohydrates, may also be helpful.

    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.

    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.

    Radionuclide hepatobiliary imaging with Tc-99m IDA is a useful procedure for the diagnosis of acute cholecystitis. Visualization of the gallbladder essentially rules out acute cholecystitis. Nonvisualization suggest acute cholecystitis but may also be associated with chronic gallbladder disease or other conditions. The authors recently observed five patients in whom a rim of increased parenchymal liver activity was seen adjacent to the gallbladder fossa. All five patients had acute gangrenous cholecystitis. The rim of increased activity appears to be a useful secondary sign of acute cholecystitis.

    The inflammatory fluid secretion by the gallbladder mucosa in experimental cholecystitis is induced by an increased prostaglandin formation and is mediated by intramural nerves. In the present study the effect of VIP-antiserum on the inflammatory fluid secretion in the gallbladder was tested in a validated experimental model in cats. The animals were studied in acute experiments 6 weeks after a procedure when the cystic duct was tied and gallstones were implanted in the gallbladder. During basal conditions there was a continuous secretion of fluid into the lumen of the inflamed gallbladder averaging 0.43 +/- 0.18 ml/h. Injection of VIP antiserum, obtained from immunized rabbits and diluted with saline 1:10 in a bolus of 4 ml into the coeliac artery reversed this secretion into an absorption of 1.72 +/- 0.44 ml h-1 (P < 0.001). VIP-antiserum did not affect the fluid adsorption in control animals with an intact gallbladder and injection of control serum from rabbits not immunized to VIP did not affect fluid secretion in the inflamed gallbladders. The results support the idea that the inflammatory fluid secretion in the gallbladder mucosa is mediated by VIP-ergic nerve fibres.

    Laparoscopic cholecystectomy is the procedure of choice for symptomatic cholelithiasis. However, in the presence of acute cholecystitis, 10% to 15% of patients face conversion to laparotomy. Alternatives to conventional therapy may therefore help to improve the clinical outcome of patients with complicated gallbladder disease. In selecting patients for alternative therapies, preoperative and intraoperative factors must be considered. Preoperative factors include the severity of biliary disease and preexisting medical risk factors; whereas intraoperative factors include conditions at the time of surgery that make dissection difficult or unsafe. Alternative therapies provide the least invasive management to safely temporize or definitively treat the acute condition. These alternatives include percutaneous cholecystostomy alone or followed by laparoscopic cholecystectomy, laparoscopic cholecystostomy followed by laparoscopic cholecystectomy, laparoscopic subtotal cholecystectomy, endoscopic retrograde cannulation of the gallbladder, and extracorporeal shockwave lithotripsy. By appropriate selection of the initial therapeutic approach, the surgeon may ultimately improve the clinical outcome in these complicated patients.

    Duodenal perforation in childhood is a rare condition with a high mortality rate if not treated surgically. Primary gastroduodenal perforation is frequently associated with peptic ulcer and exhibits a positive family history. Helicobacter pylorus is the most significant agent. Secondary gastroduodenal perforation may be a finding of specific diseases, such as Crohn disease, or more rarely may be associated with diseases such as cystic fibrosis or sickle cell anemia. A 14-year-old boy presented with abdominal and back pain. The patient was operated on for acute abdomen and diagnosed with duodenal perforation. Helicobacter pylorus was negative. There was no risk factor to account for duodenal perforation other than sickle cell anemia. Surgical intervention was successful and without significant sequelae. Duodenal perforation is a rare entity described in patients with sickle cell anemia. To our knowledge, this is the first report of duodenal perforation in a patient sickle cell anemia. PMID:25422692

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.

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.

Histological examination of the gallbladder demonstrated a benign adenomatous polyp. Although the experience with polypoid lesions of the gallbladder in children is limited, we currently recommend cholecystectomy because these lesions are associated with acalculous cholecystitis, and because their long-term effects are unknown.

    Spontaneous perforation of the biliary ductal system is a rare cause of peritonitis with a high morbidity and mortality rate. We present a case of an 80-year-old female who presented to the Emergency Department with acute onset abdominal pain and peritoneal signs. She was taken to the operating room for exploratory laparotomy and discovered to have a perforation of her right hepatic duct. Several risk factors were found to play a role in her biliary perforation: biliary calculi, infection, and vessel thrombosis. She underwent a cholecystectomy, choledochotomy with removal of gallstones, repair of the perforation, and placement of a T-tube. She had a prolonged recovery in the intensive care unit and was eventually discharged to a skilled nursing facility. We conclude that the management of this unique and highly fatal disease can be applied with an excellent outcome.

    As a mechanical complication of acute myocardial infarction, ventricular septal perforation (VSP) occurs mostly within 1 week after infarction. Although incidence of the disease is only 1-2% of transmural infarction, patients are into serious condition progressively once it happens. Even if patients were treated medically under intensive care protocol, they would almost always present congestive heart failure due to massive volume overload. Hence VSP should be treated surgically as soon as possible after its onset. We believe that infarct exclusion technique is standard procedure of surgical treatment, because it is relatively simple, makes less bleeding and gives minimal damage to right ventricle. Acute mortality has come down to 10-20% after introduction of this procedure. Cardiogenic shock before surgery, severe right heart failure and high age are important predictors of death. It is still difficult to save patients who are in severe cardiogenic shock with very low ventricular function. New treatments such as ventricular assist device, heart transplantation and regeneration therapy are waited for this high risk group of patients.

    Biliary sludge in dogs is dismissed commonly as an incidental finding. On the other hand, gallbladder mucocele is reported increasingly in dogs and can lead to biliary obstruction or gallbladder rupture. Cholestasis is suspected to play a role in development of sludge and mucoceles, though there are no data in dogs to support this. We investigated gallbladder emptying, a key factor in biliary flow, in dogs with mobile sludge, immobile sludge, or gallbladder mucocele and in healthy controls. Gallbladder ejection fraction estimated by ultrasonography was used as the index of gallbladder emptying. The ejection fraction at 60 min after eating was significantly decreased in all three abnormal groups. Moreover, all dogs with sludge or a mucocele had gallbladder distension. These changes were the greatest in the mucocele group. Thus, biliary stasis occurs not only in dogs with gallbladder mucocele but also in dogs with biliary sludge. Cholestasis may play a role in the pathogenesis or progression of these diseases in dogs.

    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.

    Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    Congenital absence of the gall-bladder is a rare condition. It is sometimes associated with other congenital defects. We report here two cases of gall-bladder agenesis discovered at laparoscopy. Both had a history of skeletal and cardiovascular anomalies. The investigation of patients with absent gall-bladder can be very difficult. Ultrasound scanning is usually inconclusive and further noninvasive tests should be performed to establish the diagnosis and prevent an unnecessary operation. The presence of other congenital defects should alert the clinician to the possibility of gall-bladder agenesis. PMID:18612357

    In recent years, endoscopic ultrasonography (EUS) has emerged as an important tool for the diagnosis and management of pancreaticobiliary disease. The close proximity of the echoendoscope to the biliary system allows detailed imaging of the gallbladder and adjacent structures. EUS is useful for the detection of occult cholelithiasis and biliary sludge and in the evaluation of suspected choledocholithiasis. It can be used to classify and predict neoplasia in polypoid lesions of the gallbladder and also to diagnose and stage gallbladder carcinoma. This article reviews the use of EUS in these diseases of the gallbladder.

    We report the unusual case of a plexiform fibromyxoma, occasionally assessed in a lithiasic gallbladder. The full thickness assessment of the gallbladder wall revealed an intra-mural, well demarked multi-nodular tumor (1 cm), consisting of a plexiform growth of spindle cells, included within a fibromyxoid stroma with a rich micro-vascular network. The tumor cells featured no nuclear atypia, nor mitotic activity. At the immunohistochemical profiling, the spindle shaped cells unequivocally featured vimentin, SMA, HHF35, collagen IV, and CD34; no cells expressed CD117, PDGFRA, CD10, desmin, GFAP, EMA, and S-100. Faint STAT6 nuclear expression was observed in isolated tumor cells. The molecular profiling did not revealed any CKIT and PDGFRA genes mutations. The uncommon site of the tumor presentation and its aberrant CD34 expression both confer to the reported case a unique place among the myxoid tumors of the gastrointestinal tract.

    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.

    Late-onset congenital diaphragmatic hernias that give symptoms beyond the neonatal period are rare and are difficult to diagnose. The diagnosis is usually made in case of complications such as intestinal obstruction, strangulation, and perforation, which further necessitate immediate surgical repair. The case of a 5-year-old child presenting with acute respiratory distress with gastric strangulation and perforation secondary to Bochdalek hernia is reported here. Although presentation in the latter ages is less common, congenital diaphragmatic hernia should be included in the differential diagnosis of respiratory distress in children. Symptoms and diagnostic tools should truly be interpreted. Gastrointestinal complications must urgently be recognized, and early surgical intervention must be performed.

    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.

    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.

    Acute abdomen in dengue, a common arboviral disease found in tropical and subtropical countries, is not uncommon and can occasionally present as acute surgical emergency requiring urgent surgical intervention. The spectrum of acute abdomen presenting as surgical emergency in dengue infection that raises suspicion of an abdominal catastrophe includes acute appendicitis, acute cholecystitis, appendicitis and, rarely, intestinal perforation. All cases of intestinal perforation including appendicular, gastric and jejunal perforation have been reported in adult patients during the course of dengue infection. However, intestinal perforation during the course of dengue infection in the paediatric age group has never been reported. We report two cases of ileal perforation in children occurring during the course of dengue infection. PMID:27485879

    Gallbladder carriage of invasive Salmonella is considered fundamental in sustaining typhoid fever transmission. Bile and tissue was obtained from 1,377 individuals undergoing cholecystectomy in Kathmandu to investigate the prevalence, characteristics and relevance of invasive Salmonella in the gallbladder in an endemic area. Twenty percent of bile samples contained a Gram-negative organism, with Salmonella Typhi and Salmonella Paratyphi A isolated from 24 and 22 individuals, respectively. Gallbladders that contained Salmonella were more likely to show evidence of acute inflammation with extensive neutrophil infiltrate than those without Salmonella, corresponding with higher neutrophil and lower lymphocyte counts in the blood of Salmonella positive individuals. Antimicrobial resistance in the invasive Salmonella isolates was limited, indicating that gallbladder colonization is unlikely to be driven by antimicrobial resistance. The overall role of invasive Salmonella carriage in the gallbladder is not understood; here we show that 3.5% of individuals undergoing cholecystectomy in this setting have a high concentration of antimicrobial sensitive, invasive Salmonella in their bile. We predict that such individuals will become increasingly important if current transmission mechanisms are disturbed; prospectively identifying these individuals is, therefore, paramount for rapid local and regional elimination.

    When faced with a patient with possible acute cholecystitis, technetium-99m-HIDA scintigraphy should be the primary diagnostic procedure performed. If scintigraphy reveals a normal gallbladder, acute cholecystitis is excluded. If the scintigram fails to visualize the gallbladder, ultrasonography is deemed advisable to exclude potential false-positive scintigrams and confirm the presence of cholelithiasis.

    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

    The effects of methyl tert-butyl ether exposure on the human gallbladder in five patients who were treated for gallstones by contact dissolution is described. Two patients underwent cholecystectomy within 1 week of methyl tert-butyl ether treatment, one patient 2 weeks after, another 10 weeks after, and one 12 weeks after. Indications for cholecystectomy were bilirubinate stones (resistant to methyl tert-butyl ether), catheter dislodgement, bile leakage, and gallstone recurrence (2 patients). Gallstones were dissolved completely in three patients, there was approximately 50% stone reduction in one patient, and no dissolution occurred in the fifth patient. Each gallbladder was examined grossly and histologically. Electron microscopic evaluation was performed in one cases. Typical inflammatory findings of chronic cholecystitis were observed in each gallbladder and were most conspicuous in the submucosa; the mucosal and serosal surfaces were intact. Mild acute inflammatory changes were noted in the submucosa in the two patients with the shortest interval between methyl tert-butyl ether administration and cholecystectomy. There were no ulcerations in the mucosa and no unusual wall thickening or fibrosis in any patient. These observations support the safety of methyl tert-butyl ether perfusion in the human gallbladder; the mild acute changes may be a transient and reversible phenomenon.

    Background/Aims Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease worldwide. Along with the increase in the incidence of NAFLD and associated obesity, an increase in gallbladder disease (GD) has been noted. This has led to the identification of a new disease entity called fatty GD. There is a gap in the literature on the dynamics of gallbladder function in patients with NAFLD. Methods An observational case-control study, a total of 50 patients with biopsy proven NAFLD without gallbladder stone/sludge and 38 healthy comparison subjects were enrolled. Fasting, postprandial gallbladder volumes (PGV), gallbladder ejection fraction (GEF), and fasting gallbladder wall thickness (FGWT) were measured by real-time 2-dimensional ultrasonography. Results Fasting gallbladder wall thickness, fasting gallbladder volumes and PGV were significantly higher in patients with NAFLD than control subjects (P < 0.001, P = 0.006, and P < 0.001, respectively). Gallbladder ejection fraction was significantly lower in the NAFLD group than the controls (P = 0.008). The presence of NAFLD was an independent predictor for GEF, PGV, and FGWT. Also, steatosis grade was an independent predictor for GEF, and GEF was significantly lower in the nonalcoholic steatohepatitis (NASH) subgroup than the controls. Conclusions Gallbladder dysfunction and increase in gallbladder wall thickness exists in asymptomatic (without stone/sludge and related symptoms) patients with NAFLD and are useful in identifying fatty GD. Measurement of these variables in NAFLD patients may be useful in identifying those at higher risk for GD. PMID:26932908

    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.

    After malaria, schistosomiasis remains the most important tropical parasitic disease in large parts of the world. Schistosomiasis has recently re-emerged in Southern Europe. Intestinal schistosomiasis is caused by most Schistosoma (S.) spp. pathogenic to humans and leads to chronic inflammation and fibrosis of the colon as well as to liver fibrosis. Gallbladder abnormalities usually occur in patients with advanced hepatic portal fibrosis due to Schistosoma mansoni infection. Occasionally, gallbladder abnormalities have been seen also in children and occurring without associated overt liver abnormalities.The specific S. mansoni-induced gallbladder abnormalities detectable by ultrasound include typical hyperechogenic wall thickening with external gallbladder wall protuberances. The luminal wall surface is smooth. The condition is usually clinically silent although some cases of symptomatic cholecystitis have been described. The ultrasonographic Murphy response is negative. Gallbladder contractility is impaired but sludge and calculi occur rarely. Contrary to other trematodes such as liver flukes, S. mansoni does not obstruct the biliary tract. Advanced gallbladder fibrosis is unlikely to reverse after therapy.

    The significance of gallbladder wall thickness (GBWT) in regard to gallbladder disease (GBD) is not completely understood. Thickening of the gallbladder wall has been observed in patients with acute calculous and acalculous cholecystitis and chronic cholecystitis. However, various pathologic processes, such as gallbladder cancer and nonbiliary disorders such as liver cirrhosis and viral hepatitis, could also cause thickening of the gallbladder wall. To date, there is no report available on the genetic factors influencing GBWT. Therefore we sought to estimate the heritability (h2) of GBWT and to perform a genome-wide search to identify the susceptibility genes for GBWT, using data from the San Antonio Family Diabetes/Gallbladder Study (SAFDGS), a family study of Mexican Americans. GBWT was measured by ultrasound. After adjusting for the significant effects of age, sex, GBD (i.e., asymptomatic gallstones), metabolic syndrome, and duration of type 2 diabetes (T2DM), GBWT was found to be under significant and appreciable additive genetic influences (h2 +/- SE = 0.38 +/- 0.09, P < 0.0001). The strongest evidence for linkage occurred between markers D11S912 and D11S968 on chromosome 11q24-q25 (LOD = 2.7), where we have already shown suggestive evidence for linkage of GBD (LOD = 2.7) in a subset of our SAFDGS data. Potential evidence for linkage occurred at markers D1S1728 (1p31.1; LOD = 1.4) and D16S748 (16p13.1; LOD = 1.4), respectively. In conclusion, our study provides suggestive evidence for linkage of GBWT on chromosome 11q in Mexican Americans, and future tasks of mapping susceptibility gene(s) for GBD and its related traits, such as GBWT, in this chromosomal region can be fruitful.

    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.

    Experimental and clinical data support the role of oxidative stress in the development of gastro-duodenal inflammatory lesions and peptic ulcer. Although quite common, stress ulcer remains a minor concern in the The authors review the literature data and perform a retrospective study on 205 personal cases of gastroduodenal ulcers, diagnosed and operated in the period 1986-2005. Of these, 58 (28.29%) were perforated ulcers, including 4 cases (6.8%) caused by various psychic traumas. All the patients presented symptoms and signs characteristic for perforated ulcer and were undoubtedly of psychogenic cause. The surgical treatment consisted in the closure of the perforation and peritoneal drainage. Besides medical treatment of peptic ulcer disease consisting of antisecretory drugs, antioxidants and sedatives were used. Postoperative follow-up showed a rapid and uneventful recovery in all cases. In conclusion, surgery is the mainstay of treatment in perforated ulcer, but additional stress therapy promotes healing and may reduce postoperative morbidity in cases with certain involvement of psychic trauma.

  4. 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.

    During percutaneous coronary intervention, coronary perforation is one of the most feared life-threatening complications, as it may cause cardiac tamponade or acute myocardial infarction. The incidence of this serious complication in recent years has increased from 0.2 to 0.6%, most likely due to the increase of complex procedures. However, the management of coronary perforation has not been established yet. We report the first case of coronary perforation successfully managed with intracoronary injection of hydrogel microspheres.

    A 78-year-old man with rheumatoid arthritis, arteriosclerosis and cardiac arrhythmias (Lown grade IVb) was admitted to hospital because of haematemesis. Gastroscopy revealed a narrow, deformed duodenal bulb with a bleeding ulcer crater on the posterior wall and a mucosal protrusion 1 cm in diameter. In the course of the illness the duodenal bulb obstruction increased further and there was recurrent vomiting. Repeat gastroscopy 7 days later showed a gallstone, about 4 cm in diameter, which had perforated into the duodenal bulb and could not be removed endoscopically. Because of the serious nature of the other diseases an operation was not undertaken, but an ultrasound-guided extracorporeal shockwave lithotripsy was performed. In three sessions this succeeded without complication to break up the stone, the larger fragments of which were then removed endoscopically while the small ones passed through the gut spontaneously. Subsequent ultrasonography demonstrated a shrunk, stone-free gallbladder with a cholecystoduodenal fistula. Afterwards the patient was again able to take food by mouth without any problems.

    Gallbladder cancer is the most common tumor of the biliary tract and it is associated with a poor prognosis. Unexpected gallbladder cancer is a cancer incidentally discovered, as a surprise, at the histological examination after cholecystectomy for gallstones or other indications. It is a potentially curable disease, with an intermediate or good prognosis in most cases. An adequate surgical strategy is mandatory to improve the prognosis and an adjunctive radical resection may be required depending on the depth of invasion. If the cancer discovered after cholecystectomy is a pTis or a pT1a, a second surgical procedure is not mandatory. In the other cases (pT1b, pT2 and pT3 cancer) a re-resection (4b + 5 liver segmentectomy, lymphadenectomy and port-sites excision in some cases) is required to obtain a radical excision of the tumor and an accurate disease staging. The operative specimens of re-resection should be examined by the pathologist to find any "residual" tumor. The "residual disease" is the most important prognostic factor, significantly reducing median disease-free survival and disease-specific survival. The other factors include depth of parietal invasion, metastatic nodal disease, surgical margin status, cholecystectomy for acute cholecystitis, histological differentiation, lymphatic, vascular and peri-neural invasion and overall TNM-stage.

    Seven patients received the same postoperative (Postop) external-beam irradiation (NRT) after apparent complete removal of gallbladder carcinoma between August 1983 to February 1988. A dosage of 4600 cGy were delivered on a first volume (average treated volume 0.87 liters) corresponding to this of potentially locoregional disease, completed by a boost dose of 900 cGy on the gallbladder bed. Moderate acute side effects were seen in five patients; regressive dyspepsia in three and mean weight loss of 1.5 kg in three. The minimum follow-up is 5 months and the maximum is 58 months. Five patients are alive with no evidence of disease (NED) after 5, 9, 11, 31, and 58 months, respectively. One died at 12 months with local recurrence, liver metastasis, and peritoneal implants. Another one died at 26 months of abdominal recurrence. With regard to the natural history of this tumor, the dismal results obtained by surgery alone, and our preliminary data, we advocate Postop adjuvant XRT as a safe treatment.

    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.

  12. Gallbladder carcinoma: Prognostic factors and therapeutic options

    PubMed Central

    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

    As patients with carcinoma of the esophagus live longer, complications associated with the use of a gastric conduit are increasing. Ulcers form in the gastric conduit in 6.6% to 19.4% of patients. There are a few reports of perforation of a gastric conduit in the English literature. Almost all of these were associated with serious complications. We report a patient who developed a tension pneumothorax consequent to spontaneous perforation of an ulcer in the gastric conduit 7 years after the index surgery in a patient with carcinoma of the gastroesophageal junction. He responded well to conservative management. Complications related to a gastric conduit can be because of multiple factors. Periodic endoscopic surveillance of gastric conduits should be considered as these are at a higher risk of ulcer formation than a normal stomach. Long term treatment with proton pump inhibitors may decrease complications. There are no guidelines for the treatment of a perforated gastric conduit ulcer and the management should be individualized.

    Perforated peptic ulcer is a common emergency condition worldwide, with associated mortality rates of up to 30%. A scarcity of high-quality studies about the condition limits the knowledge base for clinical decision making, but a few published randomised trials are available. Although Helicobacter pylori and use of non-steroidal anti-inflammatory drugs are common causes, demographic differences in age, sex, perforation location, and underlying causes exist between countries, and mortality rates also vary. Clinical prediction rules are used, but accuracy varies with study population. Early surgery, either by laparoscopic or open repair, and proper sepsis management are essential for good outcome. Selected patients can be managed non-operatively or with novel endoscopic approaches, but validation of such methods in trials is needed. Quality of care, sepsis care bundles, and postoperative monitoring need further assessment. Adequate trials with low risk of bias are urgently needed to provide better evidence. We summarise the evidence for perforated peptic ulcer management and identify directions for future clinical research.

    Shockwave disintegration of gallbladder stones with lythic therapy of residual fragments is successful when all criteria of patient- and stone-selection, shockwave application and lysis are fulfilled. The "Four-S-stones" proved to be the best candidates: solitary, symptomatic, sonolucent in a sufficiently contractile gallbladder. The rate of complications is low. Stone recurrence rate (10 to 15% after three years) is much lower as in previous studies using lythic therapy only. The new therapeutic approach to gallbladder stone disease with fragmentation, spontaneous fragment-clearance and lysis of residual fragments is--as the only truly non-invasive procedure--for 10 to 20% of the patients an alternative equal to operation.

    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.

    Extracting the shape of the gallbladder from an ultrasonography (US) image allows superfluous information which is immaterial in the diagnostic process to be eliminated. In this project an active contour model was used to extract the shape of the gallbladder, both for cases free of lesions, and for those showing specific disease units, namely: lithiasis, polyps and changes in the shape of the organ, such as folds or turns of the gallbladder. The approximate shape of the gallbladder was found by applying the motion equation model. The tests conducted have shown that for the 220 US images of the gallbladder, the area error rate (AER) amounted to 18.15%.

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

    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.

    Peptic ulcer in the excluded segment of a gastric bypass performed in the management of morbid obesity has only rarely been reported in the literature. The purpose of this study is to review our experience with the condition in a series of 4300 patients who underwent gastric-restrictive surgery between 1978 and 1997. Eleven patients presented with acute perforation of a peptic ulcer in the excluded gastric segment. Nine ulcers were duodenal, one was gastric, and one patient had both gastric and duodenal perforations. The time between primary gastric-restrictive surgery and ulcer perforation varied from 20 days to 12 years. All patients presented with upper abdominal pain. The classical radiological sign of perforated peptic ulcer, free air under the diaphragm, did not occur in any patient. Nine patients were initially treated by primary closure of the perforation with subsequent definitive ulcer therapy by vagotomy, pyloroplasty, or gastrectomy. One case, initially treated elsewhere, was managed by placement of a Malecot catheter through the duodenal perforation, gastrostomy, and peritoneal drainage. One recent case remains symptom-free on H2 blockers after simple closure. There was no mortality. Six cases were previously reported in the literature with a 33 per cent mortality rate.

The patient suffered a bout of hematemesis, following which an endoscopy showed a bleeding blood vessel at the edge of the perforation. We performed an emergency distal gastrectomy, including the ulcer site. Histopathological examination revealed tuberculous granulation tissue and acid-fast bacilli in the ulcer. The patient was given antituberculosis therapy (ATT) postoperatively, and was well when last seen 1 year 5 months after surgery. We analyzed the clinical data of five cases of tuberculous gastric perforation (TGP), reported between 1948 and 2003, including our patient. The patients ranged in age from 21 to 45 years, with a mean age of 36.8 years (SD +/- 10.21), and a male to female ratio of 3 : 2. The diagnosis was confirmed by surgery or autopsy. Abdominal lymphadenopathy was present in all patients. Gastrectomy was performed in four patients, and two were given ATT. All four patients in the previous reports died of their disease.

    Ipilimumab, an anticancer drug, is an anti-CTLA4 monoclonal antibody. It is used in treatment of disseminated melanoma. Therapy is associated with high risk of complications. One of the most serious, although one of the rarest is perforation of gastrointestinal tract. In this case report we describe a 52-year old male, with disseminated melanoma with unknown starting point, treated with anti- CTLA4 monoclonal antibody. After 3rd dose of drug administration, bloody diarrhea and acute abdominal pain occurred as a symptom of gastrointestinal perforation. A single perforation was sutured during laparotomy. Symptoms of acute abdomen returned after 10 days. Pus-faecalperitonitis, symptoms of necro-hemorrhagic colitis and multilocal perforation of the colon were found during relaparotomy. Pancolectomy with end ileostomy was performed. Few hours since relaparotomy pacient died due to multiple organ failure. The purpose of this case report is to draw attention to a risk of multilocal colon perforation in patient treated with ipilumumab.

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

    A case of primary leiomyosarcoma of the gallbladder is reported together with a review of the literature. The nonspecific clinical picture of the disease and the consequent high frequency of misdiagnosis are stressed. Cholecystectomy combined with chemotherapy and radiotherapy is the treatment of choice suggested.

    Complicated Taeniasis necessitating surgical intervention is extremely rare and is usually reported to occur in the distal ileal region of the Gastrointestinal tract. A case of peritonitis secondary to proximal jejunal perforation due to Taenia saginata is presented. Preoperative evaluation suggested the diagnosis of acute duodenal ulcer perforation. Although no real change in management and outcome is present, Taenia remains an exceptional direct cause of intestinal perforation, and should be kept on the list of differential diagnosis of peritonitis and acute abdomen in endemic geographical locations.

    In a retrospective analysis of 218 hepatobiliary studies in patients clinically suspected of acute cholecystitis, a rim of increased hepatic activity adjacent to the gallbladder fossa (the rim sign) has been evaluated as a scintigraphic predictor of confirmed acute cholecystitis. Of 28 cases with pathologic confirmation of acute cholecystitis in this series, 17 (60%) demonstrated this sign. When associated with nonvisualization of the gallbladder at 1 hr, the positive predictive value of this photon-intense rim for acute cholecystitis was 94%. When the rim sign was absent, the positive predictive value of nonvisualization of the gallbladder at 1 hr for acute cholecystitis was only 36%. As this sign was always seen during the first hour postinjection, it can, when associated with nonvisualization, reduce the time required for completion of an hepatobiliary examination in suspected acute cholecystitis.

    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. PMID:23907944

    Summary Perforated peptic ulcer (PPU) is a frequent emergency condition worldwide with associated mortality up to 30%. A paucity of studies on PPU limits the knowledge base for clinical decision-making, but a few randomised trials are available. While Helicobacter pylori and use of non-steroidal anti-inflammatory drugs are frequent causes of PPU, demographic differences in age, gender, perforation location and aetiology exist between countries, as do mortality rates. Clinical prediction rules are used, but accuracy varies with study population. Early surgery, either by laparoscopic or open repair, and proper sepsis management are essential for good outcome. Selected patients can perhaps be managed non-operatively or with novel endoscopic approaches, but validation in trials is needed. Quality of care, sepsis care-bundles and postoperative monitoring need further evaluation. Adequate trials with low risk of bias are urgently needed for better evidence. Here we summarize the evidence for PPU management and identify directions for future clinical research. PMID:26460663

    Ultrasonography of the gallbladder was performed in 3 groups of dogs: 30 clinically healthy dogs, 50 dogs with hepatobiliary disease, and 50 dogs with diseases other than hepatobiliary disease. The gallbladder was evaluated for the presence of sludge (echogenic material without acoustic shadowing). Maximal gallbladder length, width, height, and area were measured as well as the gallbladder wall thickness. The relative sludge area was calculated as the ratio of sludge area over gallbladder area on longitudinal images. No significant difference was found in the prevalence of gallbladder sludge among healthy dogs (53%), dogs with hepatobiliary diseases (62%), and dogs with other diseases (48%). The mean age of dogs with sludge was higher than the mean age of dogs without sludge in dogs with hepatobiliary disease and dogs with other diseases (p < 0.05). The mean relative sludge area did not differ significantly among the 3 groups. A trend to larger gallbladder dimensions in dogs with sludge compared to dogs without sludge was detected within the 3 groups. The gallbladder wall thickness was not different between dogs with and without sludge within the 3 groups. However, the gallbladder wall was more frequently isoechoic than hyperechoic to the liver in dogs with sludge than in dogs without sludge. The results of this study indicate that gallbladder sludge, in dogs, is not particularly associated with hepatobiliary disease and should be considered an incidental finding.

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.

    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

    The upper limit of normal time for gallbladder visualization employing Tc-99m disofenin has been set at 60 minutes by the manufacturer. In the authors' experience the great majority of normal gallbladders are seen by 30 minutes so the authors investigated the clinical correlates of gallbladder visualization between 30 and 60 minutes. Three hundred twenty-three consecutive patients were studied, with 133 showing no gallbladder visualization, 155 with visualization under 30 minutes (14 of these with cholelithiasis), 26 with visualization between 30-60 minutes, and 9 with more delayed visualization. Of the 26 with gallbladder seen between 30-60 minutes only 35% had a normal hepatobiliary system. Only the scans with elevated bilirubin or filling defects were read as abnormal. It is concluded that almost two-thirds of patients with gallbladder visualization first occurring between 30-60 minutes still have some hepatobiliary disorder.

    Uterine perforation, a major complication of dilatation and curettage (D&C), is typically recognized at the time of the procedure. Large defects in the uterine wall or injury to other intraabdominal organs can result in an acute abdomen requiring immediate surgical treatment. On the other hand, small perforations usually resolve on their own without any long-term consequences. Here, the authors report a case of delayed hemoperitoneum, ten days after the D&C evacuation of an early pregnancy. Initially, intramural pregnancy was the suspected etiology. However, histopathology suggested that the inciting event was the rupture of a serosal uterine hematoma, which likely resulted from an incomplete uterine perforation during D&C. The patient did well after undergoing an uneventful laparoscopy.

    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.

    Lymphoepithelioma-like carcinoma (LELC), an undifferentiated carcinoma with intense lymphoplasmacytic infiltrates, is commonly reported in the nasopharynx and occasionally in other organs. Pure type of LELC has previously been reported in the gallbladder. Mixed type could be reportable in comparison with other organs. Here we present a case of an 83-year-old man with mixed LELC and adenocarcinoma in the gallbladder. To the best of our knowledge, this is the first case of mixed LELC and adenocarcinoma in the gallbladder.

    The mechanisms involved in the impaired gallbladder contractile response in chronic acalculous cholecystitis are unknown. To determine the mechanisms that may lead to impaired gallbladder emptying in chronic acalculous cholecystitis, gallbladder specimens removed during hepatic resection (controls) and after cholecystectomy for chronic acalculous cholecystitis were attached to force transducers and placed in tissue baths with oxygenated Krebs solution. Electrical field stimulation (EFS) (1 to 10 Hz, 0.1 msec, 70 V) or the contractile agonists, CCK-8 (10(-9) to 10(-5)) or K(+) (80 mmol/L), were placed separately in the tissue baths and changes in tension were determined. Patients with chronic acalculous cholecystitis had a mean gallbladder ejection fraction of 12% +/- 4%. Pathologic examination of all gallbladders removed for chronic acalculous cholecystitis revealed chronic cholecystitis. Spontaneous contractile activity was present in gallbladder strips in 83% of control specimens but only 29% of gallbladder strips from patients with chronic acalculous cholecystitis (P < 0.05 vs. controls). CCK-8 contractions were decreased by 54% and EFS-stimulated contractions were decreased by 50% in the presence of chronic acalculous cholecystitis (P < 0.05 vs. controls). K(+)-induced contractions were similar between control and chronic acalculous cholecystitis gallbladder strips. The impaired gallbladder emptying in chronic acalculous cholecystitis appears to be due to diminished spontaneous contractile activity and decreased contractile responsiveness to both CCK and EFS.

    Differentiation between complicated cholecystitis and advanced gallbladder carcinoma can be difficult when clinical findings are confusing. Computed tomographic (CT) scans were reviewed from 22 patients with a surgical diagnosis of complicated cholecystitis (11 cases) or advanced gallbladder carcinoma (11 cases). The presence of a curvilinear low-attenuation halo around the gallbladder wall was specific for complicated cholecystitis. Findings indicative of gallbladder carcinoma included a focal soft-invasion or metastases. Knowledge of these differential CT findings may result in a more accurate preoperative diagnosis.

    Marked gallbladder concentration of glucoheptonate during renal function studies in dogs prompted a prospective study in order to assess the frequency of similar findings in human subjects. Of a total of 62 patients studied, the gallbladder was visualized clearly in 17 of the 18 patients (94%) who had documented normal hepatobiliary and renal function, and who were examined in a fasted state. In 38 nonfasting patients, only eight (22%) had gallbladder visualization. These findings may prove important in the interpretation of glucoheptonate renal studies in order to avoid confusion caused by a glucoheptonate-filled gallbladder lying close to the right kidney.

    The Authors have analyzed all different methods for the treatment of gallbladder stones which are performed today: the non invasive treatment of the gallstones (oral dissolution therapy and the extracorporeal shockwave lithotripsy), the minimally invasive procedures (contact dissolution therapy and the cholecystolithotomy) and at the end the new surgical techniques (the "minicholecystectomy" and the laparoscopic cholecystectomy). From this study and their experience, based upon 1346 standard cholecystectomy, the Authors have reached the following conclusions: 1) the cholecystectomy remains the only definitive therapy for the gallbladder stones and it is the gold standard to which must be compared the other alternative therapies; 2) the laparoscopic cholecystectomy, even though introduced recently, would become the only method used for cholecystectomy.

    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.

    Spontaneous perforation of the common bile duct (CBD) is a rare event in adults. Most cases of CBD perforation are iatrogenic after invasive procedures such as endoscopic retrograde cholangiopancreatography (ERCP) or cholecystectomy. We report a case of an 81-year-old woman who presented with severe right upper abdominal pain, fever, and chills. Abdominal CT showed multiple gallbladder and CBD stones and loculated fluid collection in the inferoposterior portion of the stomach. ERCP showed the leakage of contrast media into the peritoneal cavity from the CBD. We performed endoscopic sphincterotomy (EST) and endoscopic nasobiliary drainage (ENBD) to decompress the CBD instead of emergent surgical intervention. One week later, cholangiography via ENBD tube revealed that there was no more leakage of the contrast media from the CBD. We performed cholecystectomy, removal of the CBD stones after exploration of the CBD, and T tube insertion. The perforated site of the CBD was closed and there was no more fluid collection in the inferoposterior portion of the stomach. Medical treatment including endoscopic procedures was useful for healing of the perforated CBD. PMID:15908770

Aim: The work was to study the efficacy of percutaneous peritoneal drainage under local anesthesia supported by conservative measures in high risk elderly patients, according to the American Society of Anesthesiologists grading, with perforated duodenal ulcer. Patients and Methods: Twenty four high risk patients with age >65 years having associated medical illness with evidence of perforated duodenal ulcer. Results: The overall morbidity and mortality were comparable with those treated by conservative measures alone. Conclusion: In high risk patients with perforated peptic ulcer and established peritonitis, percutaneous peritoneal drainage under local anesthesia seems to be effective with least operative trauma and mortality rate.

    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

    Objectives: To investigate the clinical, pathological, and sonographic characteristics of unexpected gallbladder carcinoma (UGC). Methods: Of 5424 patients who had undergone cholecystectomy from December 2006 to October 2013, 54 patients with primary gallbladder carcinomas confirmed by pathological diagnosis were identified. The patients were divided into two groups: diagnosed before operation (n=34) and UGC groups (n=20), of whom the clinical, pathological, and sonographic characteristics were compared. Results: No significant differences in age, gender, location of lesion, histological type, length of the gallbladder, existence of biliary sludge, and intestinal gas interference between the two groups were found (all P>0.05). The clinical symptoms, laboratory abnormalities, tumor markers, coexisting gallbladder stones, lesion size, lesion type, degree of differentiation, and tumor staging showed statistically significant differences between the two groups (all P<0.05). On ultrasound, the width of the gallbladder, gallbladder wall thickness, vascularity on color Doppler ultrasound, and bile volume in the gallbladder showed significant differences (all P<0.05). Conclusions: UGCs are commonly found at an early stage, often well-differentiated, wall thickened, and are generally accompanied with cholelithiasis. UGCs should be taken into consideration in cases with cholelithiasis or small gallbladder on ultrasound. PMID:26379911

    There are currently no reports of identification of stem cells in 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.

    /sup 99m/Tc IDA compounds have been used in the quantitative analysis of motor function of the gallbladder. However, stimuli to provoke emptying have been variable and frequently nonphysiologic. To determine the utility and dependability of provocative agents for gallbladder emptying, we studied the effects of Lipomul, CCK, and TRH after the intravenous administration of /sup 99m/Tc disofenin. Computer processing of region-of-interest over the gallbladder permitted time/activity analysis of each study and computation of the ejection fraction (EF). Results showed that Lipomul consistently produced an effect on gallbladder emptying (EF 16-42%). CCK, while more dramatic in response, was less predictable (EF 8-100%). TRH favored accumulation of activity and did not cause gallbladder emptying. The combination of CCK and TRH decreased the rate of gallbladder emptying produced by CCK alone. We conclude that the availability, low cost, and dependable effect on gallbladder emptying make Lipomul the gallbladder stimulant of choice for clinical use.

    The effect of the selective antimuscarinic agent, pirenzepine, on gallbladder function was studied in six healthy volunteers, using /sup 99m/Tc HIDA (N-(2,6-diethylthenyl) carbamoylmethyl iminodiacetic acid) hepatobiliary scanning. Pirenzepine, in doses that inhibit gastric acid secretion, did not alter gallbladder emptying responses to sham feeding stimulation or to a test meal.

    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. Finally, we revealed the biological processes and metabolic functions carried out by these genes through the use of GO, KEGG Pathway, and HMR2.0 that is compilation of the human metabolic reactions. We demonstrated the results of the combined analysis of the transcriptomics and affinity proteomics.

    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.

    Cecal perforation was diagnosed in a dog with a history of acute vomiting. The dog also had an adrenocortical adenoma. Intestinal perforation can be a serious complication of cortico-steroid treatment in the dog, but has not been attributable to hyperadrenocorticism. Fever and an inflammatory CBC were not observed, which could have been secondary to adrenal-dependent hyperadrenocorticism. The acute abdominal crisis associated with peritonitis required quick resolution in an attempt to save the dog, but also precluded any further diagnostic procedures for possible hyperadrenocorticism. The signs that suggested hyper-adrenocorticism in this dog included alopecia, lymphopenia, eosinopenia, high liver enzyme activities, hypercholesterolemia, and one large and one small adrenal gland. This latter finding presumably indicated negative feedback suppression and atrophy attributable to a functional adrenocortical adenoma.

    Papillary carcinoma is a rare tumor of the gallbladder. Papillary mucinous lesions of the intra- and extra-hepatic biliary tract (BT- IPMN) have been recognized. However the gallbladder is not included, except for the diffuse papillomatosis, where the sequence biliary papillomatosis to papillary carcinoma is proposed. We report a simultaneous case of gallbladder papillary neoplasia and intrahepatic duct carcinoma in situ associated with pancreaticobiliary maljunction (PBM). We proposed that double location, in our case, is more likely explained by a diffuse biliopancreatic tree disease leading to synchronous tumors arising in amenable duct. It was verified absence of continuity between gallbladder and intrahepatic bile duct site of involvement, absence of lymph node metastasis or venous involvement. This case report supports the concept of a proliferative and neoplastic process involving simultaneously the biliary tree and gallbladder associated with PBM.

    Gallbladder motility was studied in 18 obese women and in 18 lean females by means of an ultrasonographic method. The fasted and meal-stimulated gallbladder volumes as well as the amount of the ejected bile were significantly larger in the obese when compared to the lean controls. A significant positive correlation was found between the fasted or meal-stimulated gallbladder volume and the body mass as well as the obesity indices (the absolute overweight and body mass index). Moreover, the amount of the ejected bile correlated significantly with the fasted gallbladder volume. The results suggest that altered gallbladder motility should be considered a risk factor accounting for the increased incidence of gallstones in the obese.

    Novel cell surface-reactive monoclonal antibodies generated against extrahepatic biliary cells were developed for the isolation and characterization of different cell subsets from normal adult human gallbladder. Eleven antigenically distinct gallbladder subpopulations were isolated by fluorescence-activated cell sorting. They were classified into epithelial, mesenchymal, and pancreatobiliary (PDX1(+)SOX9(+)) subsets based on gene expression profiling. These antigenically distinct human gallbladder cell subsets could potentially also reflect different functional properties in regards to bile physiology, cell renewal and plasticity. Three of the novel monoclonal antibodies differentially labeled archival sections of primary carcinoma of human gallbladder relative to normal tissue. The novel monoclonal antibodies described herein enable the identification and characterization of antigenically diverse cell subsets within adult human gallbladder and are putative tumor biomarkers.

    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.

These findings suggest that prolonged fasting may be a cause for nonvisualization of a normal gallbladder.

    Introduction Porcelain gallbladder is a very rare entity that consists of a calcification of the gallbladder wall, and is associated with carcinoma in 12.5–62% of patients, although recent studies suggest weaker association. Case report We describe an 80-year-old woman who presented with colicky abdominal pain in the right upper quadrant, radiating to the back and associated with vomiting. Physical examination revealed jaundice, murphy's sign was negative. Hepatic-biliary tract ultrasound revealed porcelain gallbladder, she was referred to the surgical team for a scheduled cholecystectomy. A month later, she presented diffuse abdominal pain. Imaging studies showed a disseminated process affecting liver's segments, capsule, and hilum; and lungs. An aggressive surgical treatment was dismissed, and was referred to the oncology department. Discussion There is controversy in the harboring risk of malignancy of the porcelain gallbladder. While it seems that the current data points towards a lower risk of degeneration, it is also demonstrated that patients with gallbladder wall calcifications are indeed statistically at risk of gallbladder cancer. Laparoscopic cholecystectomy has become a safe and efficient approach recommended for patients with gallbladder symptoms directly related or unrelated to gallbladder wall calcifications. In this case, a pathological gallbladder, very quickly evolved into an inoperable tumor with a poor prognosis. Conclusion This report heightens that with US evidence of porcelain gallbladder, an urgent CT scan should be carried out to assess an underlying malignancy, and a simple cholecystectomy should be done urgently rather than on a routine elective list to prevent possible malignant change if possible.

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

    Dysregulation of gallbladder ion and water absorption and/or secretion has been linked to cholesterol crystal and gallstone formation. We have recently demonstrated that obese, leptin-deficient (Lep(ob)) mice have enlarged gallbladder volumes and decreased gallbladder contractility and that leptin administration to these mice normalizes gallbladder function. However, the effect of leptin on gallbladder absorption/secretion is not known. Therefore, we sought to determine whether leptin would alter the expression of genes involved in water and ion transport across the gallbladder epithelium. Affymetrix oligonucleotide microarrays representing 39,000 transcripts were used to compare gallbladder gene-expression profiles from 12-wk-old control saline-treated Lep(ob) and from leptin-treated Lep(ob) female mice. Leptin administration to Lep(ob) mice decreased gallbladder volume, bile sodium concentration, and pH. Leptin repletion upregulated the expression of aquaporin 1 water channel by 1.3-fold and downregulated aquaporin 4 by 2.3-fold. A number of genes involved in sodium transport were also influenced by leptin replacement. Epithelial sodium channel-alpha and sodium hydrogen exchangers 1 and 3 were moderately downregulated by 2.0-, 1.6-, and 1.3-fold, respectively. Carbonic anhydrase-IV, which plays a role in the acidification of bile, was upregulated 3.7-fold. In addition, a number of inflammatory cytokines that are known to influence gallbladder epithelial cell absorption and secretion were upregulated. Thus leptin, an adipocyte-derived cytokine involved with satiety and energy balance, influences gallbladder bile volume, sodium, and pH as well as multiple inflammatory cytokine genes and genes related to water, sodium, chloride, and bicarbonate transport.

    Although patients with gallbladder papillary adenocarcinoma (GBPA) appear to have better prognoses than patients with other pathological subtypes of gallbladder carcinoma (GBC), the clinicopathological features and outcomes of GBPA have not been fully explored. This study therefore analyzed the clinicopathological characteristics and outcomes of GBPA.This study included 16 patients with GBPA and 101 with gallbladder adenocarcinoma (GBA) not otherwise specified (NOS), all diagnosed pathologically after surgical resection. Clinicopathological and survival data were retrospectively collected and compared. Fever was significantly more common in GBPA (7/16 vs 10/101; P = 0.000). Serum carbohydrate antigen 19-9 level was increased in 1 of 9 patients with GBPA and 39 of 76 with GBA (P = 0.022). More patients with GBPA underwent curative resection (15/16 vs 54/101; P = 0.009). Pathologically, patients with GBPA were at much earlier tumor (T) (4 in situ, 8 T1; P = 0.000) and Tumor, Node, Metastases (TNM) stages (P = 0.000). The overall 1-, 3-, and 5-year survival rates were significantly higher in patients with GBPA (100%, 76.9%, and 76.9%, respectively), than in patients with GBA (72.2%, 38.8%, and 31.0%, respectively; P = 0.001). Preoperative jaundice (odds ratio 7.69; 95% confidence interval, 1.53-38.76; P = 0.013) was a significant prognostic factor in patients with GBA, but was no longer significant when the patients with GBA and GBPA were pooled together. The clinicopathological features of patients with GBPA differed from those in patients with GBA (not otherwise specified). Pooling of patients may mask prognostic factors in each group.

    A 62-year-old man with progressive thickening of the gallbladder wall visited our outpatient clinic. The biliary amylase level in the common bile duct was 19,900 IU/L and that of the gallbladder was 127,000 IU/L, although endoscopic retrograde cholangiopancreatography revealed no pancreaticobiliary maljunction. Histology demonstrated a moderately differentiated adenocarcinoma of the gallbladder. Pancreatobiliary reflux and associated gallbladder carcinoma were confirmed in the present case, in the absence of a pancreaticobiliary maljunction. Earlier detection of the pancreatobiliary reflux and progressive thickening of the gallbladder wall might have led to an earlier resection of the gallbladder and improved this patient's poor prognosis.

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.

    The prevalence of gallbladder disease (surgery or complaints) among Mexican Americans in Starr County, Texas, is demonstrated to be some threefold higher than in Framingham, with 13% and 26% of males and females, respectively, over the age of 35 years having the disease. The population aggregation of gallbladder disease in Amerindian groups and those genetically admixed with them (as the present case) is consistent with an underlying genetic mechanism which is further substantiated here by examining relative risks in sibs, offspring, and spouses of individuals with gallbladder disease. It is shown that in females under the age of 45 years, there is evidence for a significant association between gallbladder disease and diabetes beyond that which could be explained by body mass. Significant gallbladder disease by nonlinear age interaction effects was detected for serum cholesterol. The predicted regression lines of cholesterol by age were uniformly lower for individuals with gallbladder disease than those without it except for ages 40-55 years, in which the lines were equal. When coupled with previous results on diabetes, the results presented document the extent to which diabetes and gallbladder disease dominate the health status of Mexican Americans in southern Texas and likely elsewhere.

    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.

Endoscopic retrograde cholangiopancreaticography showed pancreatobiliary maljunction with proximal common bile duct dilatation. Pancreatobiliary maljunction was diagnosed. A computed tomography scan of the abdomen showed suspected gallbladder cancer and distal common bile duct obstruction. A pancreatic head mass was incidentally found intraoperative. Radical cholecystectomy with pancreatoduodenectomy was performed. The pathological report showed gallbladder cancer that was synchronous with pancreatic head cancer. In the pancreatobiliary maljunction with pancreatobiliary reflux condition, double primary cancer of the pancreatobiliary system should be awared.

    Cholescintigraphy, using 99mTc-HIDA, was employed to determine the gallbladder emptying response to sham feeding of a steak and potato meal, and to compare it with the emptying responses to direct cholinergic stimulation by bethanechol and to ingestion of the test meal. The maximal cumulative gallbladder emptying response to sham feeding was 44.1% + 10.1%, which was not significantly different from the response to bethanechol. Cholinergic blockade with atropine eliminated the emptying response to sham feeding. Also, sham feeding did not stimulate gallbladder emptying in patients with vagotomy. This study suggests that intact vagus nerves and cholinergic pathways are required in order for the gallbladder to respond to sham feeding. The precise mechanism for this effect has not been elucidated.

    In several animal models of cholelithiasis, and in humans with gallstones, hypersecretion of gallbladder mucin is observed. This study was undertaken to determine the effect of oxygen radicals on guinea pig gallbladder glycoprotein secretion in organ culture. Mucosal explants were incubated with ({sup 3}H)glucosamine hydrochloride to label glycoproteins, then exposed to oxygen radicals generated by chelated ferric iron and ascorbic acid. Marked stimulation of glycoprotein release was observed after a 30-min exposure to the oxygen radical-generating system, and the effect was inhibited by mannitol. The stimulatory effect of hydroxyl radical was not accompanied by leakage of intracellular lactate dehydrogenase. Parallel experiments with human granulocytes activated with f-Met-Leu-Phe and coincubated with gallbladder explants revealed similar results. These results indicate that oxygen radicals, especially the hydroxyl radical (OH), are capable of stimulating rapid release of mucous-type glycoproteins from gallbladder epithelium.

    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.

    Despite the aggressive nature and poor prognosis of gall-bladder cancer there is a group of patients who can achieve significant benefits from a radical surgical treatment. The possibility of obtaining long-term survival, even in case of patients with locally advanced cancer and metastases to regional lymph nodes, prompts to verify nihilistic approach to the treatment of this disease. Obviously such therapy can and should be performed only in centers specializing in hepatobiliary surgery. Due to the high recurrence rate, most of which are systemic, the hope of improving treatment outcomes should be sought in the use of combination therapy, based on a new chemotherapy and chemoradiotherapy regimens with the addition of targeted therapy. Unfortunately, the current application of these methods did not bring the expected benefits. PMID:26247506

    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.

    Blind loop syndrome after side-to-side ileocolonic anastomosis is a well-recognized entity even though its incidence and complication rates are not clearly defined. The inevitable dilation of the ileal cul-de-sac leads to stasis and bacterial overgrowth which eventually leads to mucosal ulceration and even full-thickness perforation. Blind loop syndrome may be an underestimated complication in the setting of digestive surgery. It should always be taken into account in cases of acute abdomen in patients who previously underwent right hemicolectomy.

    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.

  15. Gallbladder shape extraction from ultrasound images using active contour models.

    Gallbladder function is routinely assessed using ultrasonographic (USG) examinations. In clinical practice, doctors very often analyse the gallbladder shape when diagnosing selected disorders, e.g. if there are turns or folds of the gallbladder, so extracting its shape from USG images using supporting software can simplify a diagnosis that is often difficult to make. The paper describes two active contour models: the edge-based model and the region-based model making use of a morphological approach, both designed for extracting the gallbladder shape from USG images. The active contour models were applied to USG images without lesions and to those showing specific disease units, namely, anatomical changes like folds and turns of the gallbladder as well as polyps and gallstones. This paper also presents modifications of the edge-based model, such as the method for removing self-crossings and loops or the method of dampening the inflation force which moves nodes if they approach the edge being determined. The user is also able to add a fragment of the approximated edge beyond which neither active contour model will move if this edge is incomplete in the USG image. The modifications of the edge-based model presented here allow more precise results to be obtained when extracting the shape of the gallbladder from USG images than if the morphological model is used.

    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.

    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.

    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.

    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.

Most of the cases of gastric perforation are seen as the complications of peptic ulcer disease, the intake of NSAIDs (Non Steroidal Anti-Inflammatory Drugs), neoplastic diseases, etc. We are reporting a case of a 50 year old male who presented with a sudden onset of abdominal pain and shock and was diagnosed as acute peritonitis which was caused by a gastrointestinal perforation. An emergency exploratory laporotomy was performed and a gastric perforation repair with omentoplexy was done. However, the patient died in the post operative period due to a sudden cardiac arrest. A gastric perforation edge biopsy revealed the presence of fungal hyphae. The peritoneal fluid culture revealed Candida albicans colonies.

Here, we report the case of a 28-year-old man who came to our hospital with severe abdominal pain after smoking cocaine. Physical examination revealed generalised abdominal guarding. His X-ray did not show any free intraperitoneal air. However, there was a slightly elevated white blood cell count. Upon laparoscopic exploration of the abdomen, the -patient was found to have a generalised peritonitis secondary to a perforation of the prepyloric anterior wall. The operative procedure consisted of ulcer excision and primary closure with a pyloroplasty as well as an extensive abdominal irrigation after laparotomy.

    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

    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. PMID:26236734

    Patients with a perforation of the gastrointestinal tract need fast confirmation of diagnosis and early treatment to improve outcome. Plain abdominal x-ray does not always prove the perforation particularly at early stage. We report about a 62 year-old woman complaining of consistent abdominal pain with sudden onset. Ultrasound was taken as first diagnostic measure, revealing a perforation. The leakage was located in the stomach. Radiography confirmed the pneumoperitoneum without indicating the perforated location. During operation the perforated gastric ulcer was found and sutured. This case report points out the reliability of ultrasound in diagnosing a pneumoperitoneum. Additionally it provides a summary of ultrasound signs seen in perforated gastric and duodenal ulcers and a review of literature.

    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.

    A left-sided gallbladder without a right-sided round ligament, which is called a true left-sided gallbladder, is extremely rare. A 71-year-old woman was referred to our hospital due to a gallbladder polyp. Computed tomography (CT) revealed not only a gallbladder polyp but also the gallbladder located to the left of the round ligament connected to the left umbilical portion. CT portography revealed that the main portal vein diverged into the right posterior portal vein and the common trunk of the left portal vein and right anterior portal vein. CT cholangiography revealed that the infraportal bile duct of segment 2 joined the common bile duct. Laparoscopic cholecystectomy was performed for a gallbladder polyp, and the intraoperative finding showed that the cholecystic veins joined the round ligament. A true left-sided gallbladder is closely associated with several anomalies; therefore, surgeons encountering a true left-sided gallbladder should be aware of the potential for these anomalies.

    The AA report their 15-month experience with extracorporeal shock-wave lithotripsy (ESWL) in the treatment of gallbladder stones (GS). The selection criteria included symptomatic patients, with 1 to 3 radiolucent stones in a functioning gallbladder. All patients were put on adjuvant therapy with 10 mg/Kg weight/day of ursodeoxycholic acid (ursodiol). ESWL sessions were performed in an ambulatory setting, using high-energy shock-waves (mean: 23 Kv) until fragments < or = 4mm were obtained, if possible. By the end of December 1992, 109 patients had completed the ESWL protocol, undergoing a total of 265 sessions (mean: 2.4 sessions per patient, variation 1-5). The stone-free (SF) rates and respective 95% confidence intervals were 31% (22%-43%) at 6 months and 59% (38%-76%) at 1 year of follow-up. For the subset of patients with a single stone < or = 2 cm (n = 59), were 47% (33%-63%) at 6 months and 77% (40%-95%) at 1 year. The most significant complication was acute biliary pancreatitis, of which we report 4 cases (4%). They were always mild and non-complicated. There was no mortality. The AA conclude that ESWL is a safe and effective treatment for selected patients with GS.

    Despite increasing use of lateral lower leg perforator flaps, comprehensive anatomical data are still lacking. The aim of this article was to comprehensively document the pattern of usable lateral lower leg perforators. Systematic mapping of 16 cadaver leg perforators in a well-defined area was performed to elucidate location, course, length, diameter, and origin. Overall, 197 perforators were found in 16 lateral lower legs. The mean number of perforators per leg with a diameter ≥ 0.3 mm was 13.4 ± 3.6. Most perforators were found in the distal third (39.0%), followed by the middle third (32.0%), and proximal third (29.0%). A musculocutaneous course was found in 26.9% of the perforators, whereas 73.1% revealed a septocutaneous course. Most septocutaneous perforators (50.0%) were found in the distal third and most musculocutaneous perforators (58.5%) in the proximal third (P < 0.001). The majority of perforators originated from the anterior tibial artery (53.0%), followed by the peroneal artery (41.6%), and the popliteal artery (5.1%). Popliteal artery perforators (1.64 mm) were significantly larger than anterior tibial artery (0.91 mm) and peroneal artery perforators (1.02 mm; P < 0.001). These results may facilitate tissue transfer around the lateral lower leg.

    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

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.

  16. Variations in concentrating function of the gallbladder in the conscious monkey.

    Hepatic bile is concentrated in the gallbladder by absorption of water and electrolytes. The rate of water absorption can be influenced in vitro and in vivo by gastrointestinal hormones and neurogenic transmitters. Recent studies have demonstrated that besides its absorbing activity, the gallbladder has the ability to secrete fluid into its lumen. In the present experiments, we studied the rate of net water absorption in the gallbladders of pig-tailed monkeys sitting in restraining chairs. Bile from the common bile duct and the gallbladder was led out through cannulas to a stream splitter, samples were obtained, and bile was returned to the duodenum. By measuring outflow from the gallbladder and the concentration of bile acids in hepatic bile and bile that had passed through the gallbladder, net water absorption from the gallbladder bile could be calculated. The results demonstrate that during daytime fasting there was a net absorption corresponding to 30% of the fasting gallbladder volume per hour, and after feeding there was a net secretion of fluid into the gallbladder lumen. Compared with the awake fasting state, net water absorption from the gallbladder decreased at night while the animal was fasting and asleep. Physiologically, secretion of fluid after a meal could help to empty the gallbladder, and changes in net water absorption by the gallbladder could influence the kinetics of the enterohepatic circulation of bile acids.

    Acquired perforating dermatosis (APD) is an uncommon disease characterized by lesions exhibiting transepidermal elimination of collagen or elastic fibers. APD affects adults and is associated with systemic diseases, mainly diabetes mellitus and renal failure. We present 8 cases of APD. Seven patients had concomitant diabetes mellitus with or without chronic renal failure, and 1 had alcoholic cirrhosis. In the patients with chronic renal failure, the onset of APD coincided with transient worsening of renal function. The mean increase in creatinine concentrations above baseline was 1.14mg/dL. Acute deterioration of renal function may be involved in APD. Further studies are needed to investigate this association.

    A study of 90 wells perforated with the tubing-conveyed perforating system showed a correlation between underbalanced pressure and formation permeability that can be used to achieve clean perforations. The data, from gas and oil producers in clean sandstones, are from wells that were perforated, tested, acidized, and retested. There is a clear minimum underbalance line separating the data sets of wells that had clean perforations (unassisted by acidizing) from those wells that showed a significant productivity increase after acidizing. The study includes data from oil and gas wells in the Gulf of Mexico, Lousiana (Tuscaloosa trend), New Mexico (Morrow sandstone), Rocky Mountain overthrust, and Alberta, Canada.

    In this paper, we present a case of undifferentiated carcinoma of the gallbladder, which is a rare disease with poor prognosis. A 77-year-old woman presented with right hypochondralgia. An abdominal CT scan showed a tumor more than 80 mm in diameter invading the liver parenchyma and transverse colon, and showed liver and lymph node metastases. We diagnosed the patient with stage Ⅳ carcinoma of the gallbladder. We resected the gallbladder, S4a plus S5 of the liver, part of the transverse colon, the lymph nodes, the greater omentum, and the extra hepatic bile duct; biliary reconstruction was then performed. Histological examination showed that most areas consisted of undifferentiated cells. The diagnosis of undifferentiated carcinoma was made according to the WHO classification of tumors of the digestive system. No recurrence has been detected for 1 year. PMID:26805158

    The authors are interested in determining causes of gallbladder cancer (GBC). 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.

    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.

    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.

    Villous adenomas occur most frequently in the rectum and colon. These tumors are rarely seen in the gallbladder. We report a case of gallbladder villous adenomas in a 69-year-old patient who has systemic lupus erythematosus (SLE). The patient was admitted for investigation of a gallbladder mass. Ultrasonography, computed tomography, and magnetic resonance imaging showed two well-circumscribed lobulated masses in the gallbladder. Open cholecystectomy was performed and histological examination revealed typical features of villous adenoma. This report describes the first case of villous adenomas of gallbladder with SLE, and documents its imaging findings comprehensively. PMID:23798953

    Situs inversus totalis is a rare condition affecting intra abdominal and intra thoracic organs. Situs inversus usually remains asymptomatic. Life expectancy is normal in the absence of rare cardiac abnormalities. Left sided gallbladder can occur even without situs inversus totalis. Cholelithiasis is not more common in patients with situs inversus than the general population. However, these patients may pose a diagnostic difficulty. An ultrasound scan can confirm the presence of gallstones and the left-sided gallbladder. Here we present the case of a 40-year female with this diagnosis who was diagnosed on abdominal scanning and underwent laparoscopic cholecystectomy for left sided cholelithiasis.

    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.

    Notable causes of gastroduodenal ulcer are Helicobacter pylori infection, intake of non-steroidal anti-inflammatory agents, neoplastic disease, acid hypersecretory states and secondary peptic ulcer disease. There are case reports of healthy patients or those with risk factors for fungal infection who develop gastroduodenal ulcer perforation associated with the presence of fungi in ascitic fluid or gastroduodenal ulcer tissue but without the above-mentioned etiological factors. Thus, other factors and pathogens may be involved in the pathogenesis of perforation. The use of antifungal agents in patients following surgery for a perforated gastroduodenal ulcer is controversial. We report two cases of healthy patients who underwent surgery for perforated gastroduodenal ulcer, in whom the most frequent causes of perforation were excluded. Only the presence of Candida in the ulcer was found.

    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 comparison was performed between preoperative ultrasonographic and macroscopic findings for gallbladders and their contents in eleven dogs that were found to have any content in the gallbladder and then underwent cholecystectomy. In addition, correlation was considered between prognosis and age, hematologic analysis, serum biochemical analysis and ultrasonographic findings. Ultrasonographic findings of the gallbladder were classified into 3 patterns: 1) hyperechoic content filling the entire gallbladder and precipitated immobile content, 2) a somewhat thinner hypoechoic area in the exterior layer with a less distinctive border adjacent to the internal hyperechoic area than pattern 3 with moth-eaten or mosaic-form hypoechoic portions scattered within the internal hyperechoic area and 3) a thick hypoechoic area in the exterior layer with a distinctive border adjacent to a prominent internal hyperechoic area. The macroscopic findings of the contents mainly consisted of biliary sludge and concentrated bile in pattern 1, a softer mucous mass in pattern 2 and an elastic mucous mass in pattern 3. Pattern 2 seemed to be in the stage before the kiwi fruit-like pattern that characterizes gallbladder mucocele, suggesting disorder of the gallbladder and bile excretion as well as onset of cholangiohepatitis associated with such disorders. In regard to association with prognosis, the mean ages were 11.8 +/- 1.5 years in death cases and 8.4 +/- 2.8 years in surviving cases, while the total WBC counts were 46,600 +/- 11,912 /microL in the death cases and 18,266 +/- 9,411 /microL in the surviving cases, showing significant differences (p<0.05) in age and total white blood cell count between the two groups.

    In the diagnosis of acute cholecystitis, the interpretation of cholescintigraphy is usually not difficult. It is conceivable, however, that wth unusual location of obstructing calculi atypical images could result. Three cases were studied with cholescintigraphy and one with cholecystography in which more distal locations of obstructing calculi resulted in partial visualization of the gallbladder and erroneous interpretations were possible. Nuclear medicine radiologists should, therefore, be aware that atypical gallbladder images may be the result of unexpected location of obstructing calculi. Clues for assisting in interpretation are offered.

    Libman-Sacks (LS) endocarditis is one of the most common cardiac manifestations of systemic lupus erythematosus. Rarely, however, it can lead to serious complications, including severe valvular regurgitation or superimposed bacterial endocarditis. We describe the initial diagnostic challenges, clinical course, imaging studies and histopathological findings of a patient who presented with life-threatening lupus complicated by hemoptysis and respiratory failure secondary to a rare complication of LS endocarditis, acute mitral valve perforation. We review the current literature on valve perforation in the setting of LS endocarditis. In conclusion, although the disease is often asymptomatic and hemodynamically insignificant, it can result in serious and potentially fatal complications secondary to valve perforation, which may demand emergency surgical management.

    A 7-year-old domestic shorthair cat was evaluated for hyporexia and weight loss following endoscopic placement of an intragastric pH monitoring device. Physical examination of the cat was unremarkable, and its blood work was notable for a mild hypoalbuminemia. The cat's acute hyporexia and weight loss was attributed to discomfort associated with the intragastric pH monitoring device, as has been reported in humans. Endoscopic removal of the intragastric pH monitoring device resulted in gastric perforation. The cat underwent exploratory laparotomy for surgical resection and repair of the perforated area. To our knowledge, this is the first report of gastric perforation secondary to removal of a Bravo pH capsule. Caution may be advised when considering intragastric pH capsule removal in cats.

    Choledochal cysts are a congenital disorder of the bile duct, usually presenting in childhood. As they cause weakening of the wall of the bile duct, any distal obstruction, infection or reflux of amylase-rich fluid in the biliary tract can predispose to spontaneous perforation. A 25-year-old pregnant woman at 35 weeks of gestation presented with acute abdominal and fetal distress. On emergency laparotomy, common bile duct perforations were detected. T-tube drainage and caesarean section were performed. A t-tube cholangiogram revealed the diagnosis of a choledochal cyst with an abnormal pancreatobiliary junction and chronic pancreatitis. The patient later underwent cyst excision with Roux en Y hepaticojejunostomy. Spontaneous choledochal cyst perforation in pregnancy can be successfully managed by a two-stage operation.

    Bezoars are accumulations of human or plant fiber located in the gastrointestinal tract of both humans and animals. Patients remain asymptomatic for several years, and the symptoms develop as these accumulations increase in size to the point of obstruction or perforation. We report the case of a 21-year-old patient at 10 d postpartum, who presented with acute abdomen associated with sepsis. Given the urgency of the clinical picture, at no point was the presence of a giant bezoar at gastric level suspected, specifically a trichobezoar. The emergency abdominal and pelvic ultrasound revealed only unspecific signs of perforated hollow viscus. Diagnosis was therefore made intraoperatively. A complete gastric trichobezoar was found with gastric perforation and secondary peritonitis. The peritoneal fluid culture revealed Candida glabrata. PMID:25516871

    We studied the effect of graded antral distension on gallbladder contraction both when gastrin release was promoted (alkaline distension) and when gastrin release was blocked (acid distension) in five dogs provided with innervated antral pouch, chronic bile fistula and gastric fistula. Graded distension of the antrum caused graded gallbladder contraction as evidenced by bilirubin output even when gastrin release was completely suppressed. This nongastrin mechanism of gallbladder contraction is abolished by parenteral atropine and by transthoracic truncal vagotomy. These observations provide evidence for a cholinergic, pyloro-cholecystic reflex for gallbladder contraction that is dependent on intact long vagal pathways. Similar reflex mechanisms have been shown to be initiated by antral distension and to cause pancreatic enzyme secretion (pyloro-pancreatic reflex) or acid secretion from the oxyntic gland area of the stomach (pyloro-oxyntic reflex). It would appear, therefore, that the antrum plays a central role in the integration of upper gastrointestinal function not only through the hormone gastrin but also through neural reflex mechanisms.

    Aim Gallbladder cancer is an aggressive malignancy usually diagnosed at late stage. The molecular genetics of this cancer is heterogeneous and not well established. Mutation profiling of gallbladder cancer was performed through massarray technology with an aim to identify molecular markers involved in the tumor pathogenesis that can be helpful as markers for early diagnosis and targets for therapy. Materials and Methods Forty nine cases of gallbladder cancer were screened through Sequenom Massarray technology for 390 mutations across 30 genes in formalin fixed paraffin embedded archived tissues and the results of mutation profiling was correlated with tumor characteristics. Mutations were observed in 9 of 49 cases across four genes - TP53 (four cases), CTNNB1 (two cases), PIK3CA (two cases), and KRAS (one case). Six of these cases were well differentiated but of eight of them belonged to stage II to IV disease. Six cases had associated gallstones. Conclusion The mutation frequency found in gallbladder cancer is comparable to the data available in literature. Identification of PIK3CA and KRAS mutations would help in formulating more efficacious targeted approach for management. Studies with large number of cases would help in exploring more targets and better classification of these cancers at genetic level. PMID:24739824

    Fluorescent images of gallbladder stones, tissue and bile are obtained using a streak camera. A Match Spatial Filer (MSF) is made using a stone fluorescent image. The MSF is used to perform correlations with fluorescent tissue and bile image. A method for recognition of the stone and rejection of the tissue during the laser lithotripsy is proposed using the correlation outputs.

    A 47-year-old man who presented with epigastric pain after a meal was diagnosed with biliary sludge present in the gallbladder. Endoscopic retrograde cholangiopancreatography showed normal anatomy of the biliary tree. During the exploratory phase of a laparoscopic cholecystectomy using four ports positioned as usual, surgeons observed a left-sided gallbladder. A review of the preoperative imaging by computed tomography confirmed a round ligament connected to the right portal umbilical portion. It also established that the gallbladder was located to the left of the round ligament, and attached to the left lateral segment of the liver. Laparoscopic cholecystectomy was performed successfully in this patient with the usual port site and careful dissection with a normograde approach. The patient was discharged on the second postoperative day with an uneventful course. Prior identification of a left-sided gallbladder is possible with cautious attention. In particular, it is important for the surgeon to be aware of unusual alterations in the portal and biliary anatomy associated with this anomaly to safely complete a laparoscopic cholecystectomy.

    Changes in the radiological diagnosis of gallbladder disease are occurring at a remarkable rate. In this symposium, several recognized authorities place the various diagnostic modalities and their interrelation in modern perspective. The present and future roles of oral cholecystography and intravenous cholangiography, the radiological diagnosis of chronic acalculous cholecystitis, and the use of ultrasonography and cholescintigraphy are analyzed.

    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.

    Appendicitis is one of the most common abdominal surgical emergencies. In some cases, the correct diagnosis may be challenging, owing to different conditions that can mimic this pathology. In this context, abdominal computed tomography (CT) is the imaging modality of choice, leading to an accurate diagnosis and to a reduction in unnecessary laparotomies. The diagnosis of perforated appendix is crucial, but the detection of the perforation signs by CT may not be so simple in the early process. The aim of this article is to review the multiple detector CT signs of perforated appendicitis.

    The productivity of a perforated gas well is affected strongly by non-Darcy or turbulent flow through the compacted zone around each perforation. The turbulence coefficient depends on the permeability of this compacted zone. This permeability, a function of perforation condition, can be used with perforation dimensions to predict gas well performance.

    Progesterone (P), 17β-estradiol (E2), and dihydrotestosterone (DHT) affect gallbladder motility. When gallbladders were taken from women and men, women had more estrogen and P receptors than men. Both P and E2 had an inhibitory effect upon gallbladder contractility in men and premenopausal and postmenopausal women. Similar findings have been reported in gallbladder strips from male and female guinea pigs. In the present study, there was no significant difference in the amount of E2-, P-, or DHT-induced relaxation of CCK-induced tension when the responses in gallbladder strips from male and female guinea pigs were compared. Three metabolites of P were used: 17-hydroxyprogesterone (17-P), 20α-hydroxyprogesterone (20-P), and 21-hydroxyprogesterone (21-P). There was no significant difference in the responses from strips from male and female guinea pigs. In order to determine if the effects of E2 and P were additive, strips from male animals were exposed to either E2 or P and the amount of relaxation recorded. After recovery, the strips were exposed to E2 or P in reverse order to ensure the order of treatment had no effect. Then, the strips were treated with both E2 and P simultaneously and the relaxation recorded. This procedure was repeated with strips from female guinea pigs. The effect of E2 and P was found to be additive; however, the response of the strips from each sex were not significantly different. It is concluded that the sex of the guinea pig has no significant effect on the response to the sex hormones used. PMID:27354545

    Spontaneous perforation of the extrahepatic biliary tree during infancy is an uncommon event. The cause of bile duct perforation is unclear, but one-quarter of reported cases have been associated with a stone or bile sludge obstructing the distal common bile duct. A 4-week-old girl had jaundice, and a DISIDA (99m technetium diisopropyl iminodiacetic acid) scan revealed perforation of the biliary tree. Exploratory surgery showed distal common bile duct obstruction with proximal perforation. No attempt was made to remove the obstructing lesion because of duct inflammation. Common bile duct obstruction persisted until week 5 after surgery when cholangiography revealed free flow of contrast into the duodenum through a common bile duct of normal caliber without a filling defect. In the presence of acute inflammation associated with perforation of the biliary tree, exploration of the common bile duct to relieve a distal obstruction could prove hazardous. Our case and a review of the literature suggest that the obstructing stone or sludge may pass spontaneously if managed expectantly.

    Most chronic tympanic membrane (TM) perforations require surgical interventions such as tympanoplasty because, unlike with acute perforations, it is very difficult for the perforations to heal spontaneously. The purpose of this study was to develop novel therapeutic techniques and scaffolds that release growth factors to treat chronic TM perforations. We evaluated the cell proliferation effects of the epidermal growth factor (EGF) and fibroblast growth factor (FGF) on in vitro cultures of TM cells using an MTT assay. They both showed similar efficacy, so we used EGF because of its lower cost. We then constructed an EGF-releasing chitosan patch scaffold (EGF-CPS) based on previous studies. We analyzed its toxicity and strength, and we studied it using scanning electron microscopy. EGF was released from the EGF-CPS for 8 weeks in an in vitro system. In animal studies, the EGF group, which was treated with EGF-CPS, showed healing in 56.5% of the animals (13/23), while the control group, which did not receive any treatment, revealed 20.8% healing (4/24) (p=0.04). Transmission electron microscopic studies of regenerated eardrums in the EGF group showed much greater preservation of histological features, and TMs of the EGF group were thinner than spontaneously healed TMs. In conclusion, this novel EGF-CPS can be used as a nonsurgical intervention technique for treatment of chronic TM perforations.

    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.

    Transoesophageal echocardiography (TOE) is being used more often by cardiothoracic anaesthetists for the perioperative management of cardiac problems. Reports of iatrogenic oesophageal perforation by instrumentation of the oesophagus are increasing. Although TOE is considered safe, it may be more risky during surgery, because the probe is passed and manipulated in an anaesthetized patient. It may be in place for several hours so the risk of mucosal pressure and thermal damage is increased. Patients on cardiopulmonary bypass are also fully anticoagulated. We describe a case of oesophageal perforation following insertion of the TOE probe in a patient with gross cardiomegaly. Oesophageal distortion by cardiac enlargement may increase the risk of oesophageal perforation. Difficulty in passage of the TOE probe should be regarded with suspicion and withdrawal should be contemplated because the symptoms of oesophageal perforation are often delayed and non-specific. Delay in investigation, diagnosis and treatment will increase morbidity and mortality.

    This paper describes numerical simulation of airflow in a nose with a nasal septal perforation. Diseased airflow is compared to airflow in a healthy nasal model. The healthy model has been generated from CT scans from the Antrim Area Hospital ENT clinic and is close to being anatomically accurate. The nasal septal perforation has been superimposed on the healthy geometry using image manipulation software. The flow is modeled as laminar, steady state, with the flow rates corresponding to quiet breathing at rest approximately 165 ml/sec. Healthy flow patterns show that the majority of the flow travels close to nasal septum, in the region close to the middle turbinate. In the diseased case, high shear stresses concentrated at the posterior region of the perforation explain bleeding associated with nasal perforations.

    A 39-year-old Japanese woman was referred to our hospital for severe abdominal pain at 22 weeks and 2 days of gestation. Abdominal computed tomography (CT) suggested perforation of the gastrointestinal tract and emergency surgery was conducted. There was a fibrous adhesion between an enlarged uterus and the sigmoid colon. There was a 5.0-cm perforation near the adhesion in the posterior wall of the sigmoid colon. We performed a partial resection of the sigmoid colon and Hartmann's procedure with copious intraperitoneal lavage. Five hours following the laparotomy, uterine contractions could not be controlled and the patient delivered vaginally. The neonate died almost immediately after delivery. We conclude that although stercoral bowel perforation is rare, poor prognosis after perforation emphasizes the need to carry out a CT scan for patients who present with undiagnosed severe abdominal pain and compatible medical history, even if the patient is pregnant.

    Diverticulosis is a common disorder among geriatric patients, of whom 10% to 25% go on to develop diverticulitis. Known complications of diverticulitis include formation of phlegmon, fistula, bowel obstruction, bleeding, perforation, and colonic abscess. A less common complication is perforation with formation of an extra-abdominal necrotizing abscess. This case is a report of an 83-year-old female who presented to the emergency department with a necrotizing abdominal wall abscess secondary to right-sided diverticular microperforation.

    OBJECT The purposes of this study were to evaluate the frequency with which children presented with ventriculoperitoneal (VP) shunt perforations of the gastrointestinal (GI) tract, to determine the type of shunts that caused the perforations, and to compare the stiffness of perforating catheters with the stiffness of catheters from other manufacturers. METHODS Medical records were reviewed of 197 children who were admitted with VP shunt malfunction. Catheter stiffness was evaluated by measuring relative resistance to cross-sectional compression, resistance to column buckling, and elasticity in longitudinal bending. Catheter frictional force was measured per unit length. RESULTS Six children were identified whose VP shunts had perforated the GI tract; 2 shunts subsequently protruded through the anal orifice, 1 protruded through the oral cavity, and 3 presented with subcutaneous abscesses that tracked upward from the intestine to the chest. All perforating shunts were Chhabra shunts. Catheter stiffness and resistance to bending were greatest with a Medtronic shunt catheter, intermediate with a Codman catheter, and least with a Chhabra catheter. Frictional force was greatest with a Chhabra catheter and least with a Medtronic catheter. CONCLUSIONS The frequency of perforations by Chhabra shunts appears to be higher than the frequency associated with other shunts. The increased frequency does not correlate with their stiffness but may reflect their greater frictional forces.

    Ciliated foregut cyst of gallbladder is a very rare benign cystic lesion. A 39-year-old woman was referred to our hospital after abdominal ultrasonography revealed a cystic lesion of gallbladder. On abdominal ultrasonography and computed tomography, a unilocular cystic lesion was found at right upper quadrant with attachment to the gallbladder neck. The gallbladder with cystic lesion was resected through laparoscopic cholecystectomy. The cystic lesion revealed a unilocular cyst with ciliated cuboidal or columnar epithelium and abundant goblet cells. Pathologic examination is essential to distinguish from other cystic lesions of the gallbladder and avoid unnecessary additional treatment. In the current case report, we presented the clinico-pathologic findings of the ciliated foregut cyst of the gallbladder and review of literature. PMID:27212997

    Background: Double gallbladder is a rare anomaly of the biliary tract. Double gallbladder arising from the left hepatic duct was previously reported only once in the literature. Case Report: A case of symptomatic cholelithiasis in a double gallbladder, diagnosed on preoperative ultrasound, computed tomography (CT) and endoscopic retrograde cholangiopancreatogram (ERCP) is reported. At laparoscopic cholangiography via the accessory gallbladder no accessory cystic duct was visualized. After conversion to open cholecystectomy, the duplicated gallbladder was found to arise directly from the left hepatic duct; it was resected and the duct repaired. Conclusions: We emphasize that a careful intraoperative cholangiographic evaluation of the accessory gallbladder is mandatory in order to prevent inadvertent injury to bile ducts, since a large variety of ductal abnormality may exist.

    This is a case of a 75-year-old man being admitted to the on-call surgical department with acute abdominal pain. On arrival he was clinically dehydrated and shocked with localised pain over McBurney's point and examination findings were suggestive of appendiceal or other colonic pathology. Full blood testing revealed a white cell count of 38×109/L and a C reactive protein (CRP) of 278 mg/L. A CT scan revealed a gallbladder empyema that extended into the right iliac fossa. This case highlights the potential for a hyperdistended gallbladder empyema to present as acute right iliac fossa pain with blood tests suggestive of complicated disease. Further analysis confirmed Actinomyces infection as the underlying aetiology prior to a laparoscopic subtotal cholecystectomy. This case serves to remind clinicians of this as a rare potential cause of atypical gallbladder pathology. PMID:24872493

    Acute acalculous cholecystitis (ACC) can develop with or without gallstones after surgery and in critically ill or injured patients. Diabetes mellitus, malignant disease, abdominal vasculitis, congestive heart failure, cholesterol embolization, shock, and cardiac arrest also have been associated with AAC. The pathogenesis of AAC is complex and multifactorial. Ultrasound of the gallbladder is most accurate for the diagnosis of AAC in the critically ill patient. CT is probably of comparable accuracy, but carries both advantages and disadvantages. Rapid improvement may be expected when AAC is diagnosed correctly and cholecystostomy is performed timely.

The aim of this article was to perform an anatomical study of common digital palmar arteries perforators. Twelve injected specimens were included in this study. The purpose was to quantify the number of perforator arteries of each common digital palmar arteries in the 2nd, 3rd, and 4th intermetacarpal space, measure distances between them, between the distal perforator and corresponding commissure, and the distance between the proximal perforator and the superficial palmar arch. Four to eight perforators were arising from common digital palmar arteries of the 2nd, 3rd, and 4th intermetacarpal space. The average distance between perforator arteries was 6.5 mm, between superficial palmar arch and proximal perforator artery - 8.2 mm, between the distal perforator artery and corresponding commissure - 6.3 mm.

    Coronary perforation is a rare complication of percutaneous coronary intervention. We present two different types of coronary intervention, but both ending with coronary perforation. However, these perforations were tackled successfully by covered stents. This article reviews the incidence, causes, presentation, and management of coronary perforation in the present era of aggressive interventional cardiology. Coronary perforations are classified as type I (extraluminal crater), II (myocardial or pericardial blushing), and III (contrast streaming or cavity spilling). Types I and II coronary perforations are caused by stiff or hydrophilic guidewires. Type I has a benign prognosis, whereas type II coronary perforations have the potential to progress to tamponade. Type III coronary perforations are caused by balloons, stents, or other intracoronary devices and commonly lead to cardiac tamponade necessitating pericardial drainage. However, type III perforations can be managed with covered stents without need for surgical intervention. PMID:22121463

    Introduction Gall Bladder (GB) perforation, a rare but dreaded complication of acute cholecystitis and is associated with high mortality rate. Early detection of acute cases of GB perforation reduces the risk of biliary peritonitis and hence the associated mortality and morbidity. Aim The purpose of the study was to make a comparative evaluation of the role of Cross-sectional imaging in GB perforation with base line investigation like sonography. Finally both modalities were compared in determining the type of perforation according to Niemeier’s classification. Materials and Methods We retrospectively evaluated the Ultrasonography (USG), Computed Tomography (CT) and Magnetic Resonance Imagings (MRI) findings in patients of GB perforation with surgical correlation. Results We evaluated 17 patients of GB perforations over a time period of one year. USG was done in all patients. As cross-sectional modality only CT scan was done in 14 patients and MRI scan was done in four patients. Both CT and MRI scans were done in one patient. Conclusion Cross-sectional imaging must not be delayed in suspected cases of GB perforations because it helps in establishing a quicker diagnosis, detecting complications and also helps in decision making related to management thereby reducing the morbidity and mortality associated with this condition.

    In a prospective trial to determine whether gastric surgery induces gallbladder sludge and stone formation, 48 patients with gastric cancer were ultrasonographically examined with simultaneous observation on changes in gallbladder contractile function before and serially for 5 years after gastrectomy. Gallbladder sludge formation was induced with a high frequency of 42% 1 month after gastrectomy, with corresponding significant lowering of gallbladder contractile function. Most of gallbladder sludges, however, disappeared within 12 months in relation to the gradual recovery of gallbladder contractile function. Conversely, gallstone developed in nine patients (18.8%), mostly more than 6 months after gastrectomy. Interestingly, gallstone formation was induced in seven patients who were sludge negative. An evolvement of gallbladder sludge into stone was observed in only two patients, who were, however, treated with intravenous hyperalimentation. This study first provides evidence for the relationship between gastrectomy and a considerably high frequency of incidence of gallbladder sludge and stone in relation to changes in gallbladder kinetics after gastrectomy.

    Gallbladder visualization occurred after a Tc-99m red blood cell (RBC) cardiac gated blood pool scan. To date, seven cases of gallbladder visualization after the intravenous injection of Tc-99m RBCs have been reported. In the previous six patients the gallbladder was visualized incidentally during a search for gastrointestinal (GI) bleeding. All of the patients were anemic, six of seven had chronic renal failure, and five of seven had received multiple blood transfusions. When interpreting GI bleeding scans in patients with anemia and renal failure, awareness of the possibility of gallbladder visualization in the delayed images is important to avoid false-positive results. 3 references.

    The present light microscopy (LM) and scanning electron microscopy (SEM) studies on porcine gallbladder mucosa provide a description of the microstructures of great functional importance such as mucosal folds, the epithelium, glands, and lymphatic nodules. The results showed the regional structural differences of the porcine gallbladder wall. Depending on the part of the gallbladder, three types of mucosal structures were described: simple and branched folds and mucosal crypts. An important structural feature found in the mucosa is connected with the structural variety of type of mucosal folds, which change from simple located in the neck, to most composed, i.e., branched or joined, in the polygonal crypts toward the fundus of the gallbladder. The morphometric analysis showed statistically significantly differences in the form and size of the folds and between the fundus, body, and neck of the gallbladder. Differences in the size of mucosal epithelium are discussed in terms of processes of synthesis and secretion of glycoproteins. Regional, species-specific differences in morphology of mucosal subepithelial glands, i.e., their secretory units and openings, and intensity of mucus secretion were described. Our results on the pig gallbladder show adaptation and/or specialization in particular areas of the mucosa for (1) secretion of mucus in the neck or body of gallbladder and (2) for cyclic volume changes, especially in the fundus of gallbladder. The description of the microstructures of mucosa in the porcine gallbladder could be useful as reference data for numerous experiments on the bile tract in the pig.

    Spontaneous ruptures of the colon and rectum are extremely uncommon clinical entities and always require laparotomy. A 44-year-old female was admitted with a 12-hour history of severe abdominal pain periumbilically and at the right hypochondrium. The patient was immediately transferred to the department of surgery for close surgical observation. Computed tomography (CT) of the entire abdomen performed just before the operation demonstrated thickening of the wall of the ascending colon with pericolic fat stranding. Surgery revealed a perforation at the antimesenteric wall of the transverse colon and segmental colectomy of the transverse colon was performed. The histological evaluation demonstrated a perforated solitary ulcer of the transverse colon. There are only few known etiologic factors concerning spontaneous ruptures of the colon and rectum and usually none of these causative factors can easily be recognised. Their clinical appearance is most of the times acute abdomen and, despite the use of all appropriate diagnostic methods, the diagnosis is usually set postoperatively. PMID:20090246

    Pancreatic choristoma is the occurrence of normal pancreatic tissue in an abnormal location without any anatomic continuity with the main body of the gland. Although heterotopia is uncommon in the gallbladder and biliary tract, anecdotic cases of gastric mucosa, liver, adrenal gland and pancreas among other tissues have been described. We report an eight year-old male and a 22 year-old female, electively operated for symptomatic cholelithiasis. On pathology, a nodule identified as a pancreatic endocrine and exocrine choristoma, was found in the gallbladder wall of both patients. We employed immunohistochemistry to characterize this choristoma. Tubular and epithelial structures were immunoreactive to cytokeratins 7, 8, 18, 19 and 20 and to CA19-9. Exocrine activity was documented by immunoreactivity to al-antitrypsin and al-chemotrypsin. Other immunohistochemical markers such as insulin and somatostatin were positive identifying endocrine activity.

    We report a rare case of multiple pulmonary metastases with cavitation from gallbladder cancer. A 77-year-old woman was admitted to our hospital complaining of productive cough and exertional dyspnea. Chest X-ray film showed multiple nodular shadows with some cavitation. Computed tomography showed multiple cavities, up to 2 cm in diameter, as well as nodules, in bilateral lung fields. Under a survey of primary focus, the ultrasonographic test of the abdomen revealed a hypoechoic mass in the hepatic hilum. The patient died of respiratory failure. Autopsy findings revealed that that multiple lung tumors had metastasized from papillary adenocarcinoma of the gallbladder and that cavitation of the lung was formed by bronchioloectasis.

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

    A 58-year-old woman presented to our hospital with a huge hepatic mass. A CT scan showed an enhanced mass lesion on the fundus of the gallbladder and an enhanced mass ring on the gallbladder bed. Since FDG-PET showed no evidence of metastasis, we performed cholecystectomy, hepatectomy of S4a/5, and regional lymph node dissection. The immunohistochemical study of the specimen was positive for CK7, CK20, chromogranin A, and synaptophysin. The Ki-67 labeling index was 50%, and the SSTR2 score was 2+. The patient was diagnosed with neuroendocrine carcinoma. Since she was in poor condition and on hemodialysis, we started administration of somatostatin analog at the time of recurrence, and soon her diarrhea improved but the tumor increased in size.

    Recently it has been suggested that cholescintigraphy is unreliable in the detection of acute cholecystitis when acute pancreatitis is present. During a recent 17 month interval, twenty-one patients with a firmly established diagnosis of acute pancreatitis underwent cholescintigraphy in our laboratory. The gallbladder failed to visualize in only five cases, all of whom had acute cholecystitis. These data, and those available in the literature, lead us to conclude that cholescintigraphy is useful in the diagnosis of acute cholecystitis whether or not acute pancreatitis is present.

    Mekel's diverticulum is a gastrointestinal malformation. Occurs in one of every 40 patients. It is usually asymptomatic whereas complications can be developed in 2% to 4%. The report is based on a 41-year old male, who attended to emergency, complaining of right lower quadrant abdominal pain. Blood tests showed high level of inflammatory markers. With acute appendicitis as presumptive diagnosis, laparoscopy was performed. The intraoperative findings were: a perforated Mekel's diverticulum with normal cecal appendix. Mechanical diverticular resection was made. The patient was successfully recovered from surgery. Histopathology examination showed: Meckel's diverticulum perforated with acute inflammation and neuroendocrine tumor (G1) pT1. Mekel's diverticulum is rarely affected by inflammatory complications and just few cases are associated with tumors. However, has ever been described before, coexisting both situations, being our patient the first reported with this exceptional clinical presentation, and treated successfully by laparoscopic approach.

A 3,5-4 cm malignant gastric perforation, ascitis and peritoneal carcinomatosis were found. The histopathological exam revealed infiltrative mucinous gastric carcinoma with epiploic metastasis. Due to the lack of available gastric material, an atypical surgical solution was performed: gastric packing with epiploic material by means of transgastric traction. The solution proved to be successful for short-term recovery. The underlying condition was not focused on, the patient being directed to the Oncology Department. Acute gastric perforation is a rare complication of gastric cancer, and the association with gastric linitis is uncommon. This specific histopathological condition made the classical surgical repair techniques unsuitable for the presented case and an atypical solution had to be performed. PMID:27453758

Radiopharmaceutical quality control data, including molybdenum-99 and aluminum ion content in the Tc-99m eluate, free unbound Tc-99m, and hydrolyzed reduced Tc-99m in the labeled MDP, were all satisfactory. A minor defect in the quality of the Tc-99m generator was considered to be the probable cause of the unusual localization of the bone imaging agent.

    We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of "chyle" occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide.

    Calcium carbonate gallbladder stones were easily neglected because they were previously reported as a rare stone type in adults. The aim of this study was to investigate the relationship between calcium carbonate stones and Clonorchis sinensis infection. A total of 598 gallbladder stones were studied. The stone types were identified by FTIR spectroscopy. The C. sinensis eggs and DNA were detected by microscopic examination and real-time fluorescent PCR respectively. And then, some egg-positive stones were randomly selected for further SEM examination. Corresponding clinical characteristics of patients with different types of stones were also statistically analyzed. The detection rate of C. sinensis eggs in calcium carbonate stone, pigment stone, mixed stone and cholesterol stone types, as well as other stone types was 60%, 44%, 36%, 6% and 30%, respectively, which was highest in calcium carbonate stone yet lowest in cholesterol stone. A total of 182 stones were egg-positive, 67 (37%) of which were calcium carbonate stones. The C. sinensis eggs were found adherent to calcium carbonate crystals by both light microscopy and scanning electron microscopy. Patients with calcium carbonate stones were mainly male between the ages of 30 and 60, the CO2 combining power of patients with calcium carbonate stones were higher than those with cholesterol stones. Calcium carbonate gallbladder stones are not rare, the formation of which may be associated with C. sinensis infection.

On laparotomy, a small bowel perforation in the area of an adhesion to the abdominal wall was found. The adherent intestinal segment was located exactly in the range of the ESWL field, so that excluding further reasons the shockwave lithotripsy must be assumed to be causative.

    Background: A mathematical model to help explain the hemodynamic characteristics of perforator flaps based on blood flow resistance systems within the flap will serve as a theoretical guide for the future study and clinical applications of these flaps. Methods: There are 3 major blood flow resistance network systems of a perforator flap. These were defined as the blood flow resistance of an anastomosis between artery and artery of adjacent perforasomes, between artery and vein within a perforasome, and then between vein and vein corresponding to the outflow of that perforasome. From this, a calculation could be made of the number of such blood flow resistance network systems that must be crossed for all perforasomes within a perforator flap to predict whether that arrangement would be viable. Results: The summation of blood flow resistance networks from each perforasome in a given perforator flap could predict which portions would likely survive. This mathematical model shows how this is directly dependent on the location of the vascular pedicle to the flap and whether supercharging or superdrainage maneuvers have been added. These configurations will give an estimate of the hemodynamic characteristics for the given flap design. Conclusions: This basic mathematical model can (1) conveniently determine the degree of difficulty for each perforasome within a perforator flap to survive; (2) semiquantitatively allow the calculation of basic hemodynamic parameters; and (3) allow the assessment of the pros and cons expected for each pattern of perforasomes encountered clinically based on predictable hemodynamic observations.

  1. Gallbladder sludge: what is its clinical significance?

    PubMed

    Shaffer, E A

    2001-04-01

    Biliary sludge is a mixture of particulate solids that have precipitated from bile. Such sediment consists of cholesterol crystals, calcium bilirubinate pigment, and other calcium salts. Sludge is usually detected on transabdominal ultrasonography. Microscopy of aspirated bile and endoscopic ultrasonography are far more sensitive. Biliary sludge is associated with pregnancy; with rapid weight loss, particularly in the obese; with critical illness involving low or absent oral intake and the use of total parenteral nutrition (TPN); and following gastric surgery. It is also associated with biliary stones with common bile duct obstruction; with certain drugs, such as ceftriaxone and octreotide; and with bone marrow or solid organ transplantation. The clinical course of biliary sludge varies. It often vanishes, particularly if the causative event disappears; other cases wax and wane, and some go on to gallstones. Complications caused by biliary sludge include biliary colic, acute cholangitis, and acute pancreatitis. Asymptomatic patients with sludge or microlithiasis require no therapy. When patients are symptomatic or if complications arise, cholecystectomy is indicated. For the elderly or those at risk from the surgery, endoscopic sphincterotomy can prevent recurrent episodes of pancreatitis. Medical therapy is limited, although some approaches may show promise in the future.

    A diagnosis of small-bowel perforation, caused by a sharp or pointed foreign body, is rarely made preoperatively because the clinical symptoms are usually nonspecific and can mimic other surgical conditions, such as appendicitis and diverticulitis. We report the case of a 62-year-old woman who experienced severe pain in the right iliac fossa and fever for about five days before arrival at our hospital. The presumptive diagnosis was acute purulent appendicitis and an emergency appendectomy was planned. Swelling and erythema were noted in a segment of the small bowel in the lower right abdomen. A tiny pointed object was found penetrating the inflamed portion of the bowel, which proved to be a sharp fish bone (gray snapper). The bone was removed, followed by segmental resection of the terminal ileum and ascending colon. The postoperative course was uneventful.

    Mucin is a high molecular weight glycoprotein that plays an important role in protecting the gallbladder epithelium from the detergent effect of bile. However, it also participates in gallstone formation. There is little information about a possible relationship between gallbladder inflammation and mucin expression or gallbladder stones' characteristics. The aims of this study were to investigate stone characteristics and patterns of mucin expression in the gallbladder epithelium and bile of gallstone patients, in relation to inflammation. Gallbladder bile and tissue samples from 21 patients were obtained at surgery. Mucin content was evaluated by gel filtration on a Sepharose CL-4B column. Dot blot for bile mucin apoproteins and immunohistochemistry staining for gallbladder mucosal mucin apoproteins were performed with antibodies to MUC2, MUC3, MUC5AC, MUC5B and MUC6. Staining intensity score (0-3) was used for assessment of antigen expression and the level of inflammation. Gallstone cholesterol content was determined in 16 patients. MUC 5AC and MUC 5B were demonstrated in 95.4 and 100% of gallbladder bile samples, respectively. Immunohistochemistry staining with antibodies to MUC 2, MUC 3, MUC 5AC, MUC 5B and MUC 6 were positive in 0, 100, 85.7, 100 and 95.4% of the gallbladder mucosal samples, respectively. Pigmented brown stones were associated with a higher level of gallbladder inflammation. Mucin species expressed in gallbladder epithelium are MUC3, MUC5AC, MUC5B and MUC6. MUC5AC and MUC5B are secreted into bile. Inflammation of the gallbladder is accompanied by a higher level of MUC5AC expression and is associated with pigmented brown stones. PMID:17385041

    The study focused on the description of pig gallbladder angioarchitecture, with particular emphasis on the specifics of the course of blood vessels in individual layers of the gallbladder wall. Furthermore, the vascular systems of the pig gallbladder were analyzed in terms of the adaptation of this organ to changes in its volume during cyclical bile storage and discharge. The gallbladder is supplied by the cystic artery, which in the pig represents a mixed pinnate and bipinnate pattern of branching. The light microscopic and scanning electron microscopic observations of three-dimensional vascular corrosion casts showed the presence of two main complex vascular networks in the wall of the gallbladder, one located in the subserosal and the other in the mucosa. The unique features in the pig, connected with the size of the gallbladder, is the well-developed horizontal venous plexus under folds of the mucosa, which is a voluminous reservoir of fluids absorbed from bile and vascular networks around mucous glands. Superficial blood vessels of the gallbladder run in vascular pairs or triads, where a single artery runs between two veins. The structures of blood flow control, that is, venous valves, were observed only in venules of the subserosal plexus. Spatial arrangement of the vascular network in the pig gallbladder shows functional plasticity during changes in gallbladder volume. The course of superficial blood vessels in the well-filled gallbladder is arcuate, while in the empty gallbladder it is undulated or spiral. In the mucosal and intramural vessels the direction of blood vessels may change from perpendicular to oblique.

    The purpose of this study was to report our initial experience with a swine model for biliary interventions by using a percutaneous transcholecystic access after suture anchor of the gallbladder. Telepaque tablets were given to five pigs to opacify the gallbladder. Under fluoroscopy, the opacified gallbladder was punctured percutaneously and three suture anchors were used to fix the anterior wall of the gallbladder to the abdominal wall. Two weeks later, the gallbladder was punctured and access into the distal common bile was obtained through the cystic duct. Balloon expandable stents were deployed into the distal common bile duct. Follow-up cholangiograms were obtained at 1 and 2 weeks. Necropsy was performed after 2 weeks to evaluate the relationship between the gallbladder and abdominal wall. Suture anchor placement was successful in all five pigs. One pig with a deep and highly positioned gallbladder developed fever, anorexia, and vomiting secondary to excessive stretch of the gallbladder. Placement of the guidewire through the extremely tortuous and small cystic ducts proved to be the most challenging step of the procedure. Metallic stents were successfully deployed in all four pigs in which it was attempted. Four animals tolerated the procedures without changes in their clinical conditions and no symptoms. Successful follow-up cholangiograms were performed at 1 and 2 weeks post-stent deployment without complications. All stents remained patent during the follow-up period. Necropsy demonstrated close attachment and adherence of the gallbladders to the antero-lateral abdominal wall in all four animals. Suture anchoring of the gallbladder is feasible in most pigs with superficially located gallbladders. This technique allows a safe and repeat access into the biliary system using a transcholecystic approach.

    The majority of accidentally ingested foreign bodies is excreted from the gastrointestinal (GI) tract without any complications. Sometimes sharp foreign bodies - like chicken and fish bones - can lead to intestinal perforation and may present insidiously with a wide range of symptoms and, consequently, different diagnoses. We report the case of a 59-year-old woman presenting with fever and a 1-month history of vague abdominal pain. Computed tomography (CT) showed the presence of a hyperdense linear image close to the gastric antrum surrounded by a fluid collection and free peritoneal air. At laparotomy, a 4-cm rabbit bone fragment covered in inflamed tissue was detected next to a gastric wall perforation. Rabbit bone fragment ingestion, even if rarely reported, should not be underestimated as a possible cause of GI tract perforation.

    Through textual research of the literature on tiny collateral and perforator vessel, the two concep- tions were compared and the similarity was analyzed in terms of definition, anatomical level, quantity, the flow of qi and blood and clinical application, etc. It is considered that the tiny collateral in Neijing (Inner Canon of Yellow Emperor) and the perforator vessel of modern medicine are different names of one physical structure. It is proposed that the combination of the tiny collateral theory of CM and the research findings of perforator vessel of western medicine would deepen the understanding of the tiny structure of human skin and promote the development of both TCM and modern medicine.

    Background Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice. Aim To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation. Methods A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. ‪The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon. Results Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes. Conclusions Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.

    90 computed tomographic examinations were performed to 57 patients referred at Hospital Saint-Louis for an acute pancreatitis. 32 patients were operated or autopsied. Among these 32 patients, 19 patients had 21 examinations before surgery or autopsy; the other 13 patients had their computed tomographic examinations after one or more surgical procedures. During a severe acute pancreatitis the pancreas is always large either locally or diffusely. A pancreatic reaction is visible around and possibly at distance of the pancreas. When extraluminal gas is visible (3/5) it signifies gangrenous pancreatitis but it is necessary to eliminate a digestive fistulous tract and/or a communication between a pseudocyst and the digestive tract. Except gangrenous it is not possible to precise the nature of pancreatic reaction. The diagnosis of pseudocyst was easy 9/10, difficult 1/10; we did a false positive diagnosis of pseudocyst. Computed tomography and ultrasounds were compared in ten patients for the search of gallbladder lithiasis. Computed tomography can show large and small (2/4) biliary calculus in the gallbladder that cannot be shown by ultrasounds. A normal pancreas in a normal retroperitoneal space exclude the diagnosis of a severe acute pancreatitis. CT aspects of acute pancreatitis must be considered as a good diagnostic test of an acute pancreatitis.

    pneumonia (n = 6), mediastinitis (n = 4), osteomyelitis (n = 3), sepsis (n = 3), acute respiratory distress syndrome (n = 2), and recurrent laryngeal nerve damage (n = 1). The mortality rate of esophageal perforation in the analysis was 3.92% (6 of 153 reported patients). CONCLUSIONS Esophageal perforation after anterior cervical spine surgery is a rare complication. This systematic review demonstrates that these perforations can be stratified into 3 categories based on the timing of symptomatic onset: intraoperative, early postoperative (within 30 days of anterior spinal surgery), and delayed. The most common source of esophageal injury is hardware erosion or migration, each of which may vary in their time to symptomatic manifestation. PMID:27081708

    A left-sided gallbladder without a right-sided round ligament, which is called a true left-sided gallbladder, is extremely rare. A 71-year-old woman was referred to our hospital due to a gallbladder polyp. Computed tomography (CT) revealed not only a gallbladder polyp but also the gallbladder located to the left of the round ligament connected to the left umbilical portion. CT portography revealed that the main portal vein diverged into the right posterior portal vein and the common trunk of the left portal vein and right anterior portal vein. CT cholangiography revealed that the infraportal bile duct of segment 2 joined the common bile duct. Laparoscopic cholecystectomy was performed for a gallbladder polyp, and the intraoperative finding showed that the cholecystic veins joined the round ligament. A true left-sided gallbladder is closely associated with several anomalies; therefore, surgeons encountering a true left-sided gallbladder should be aware of the potential for these anomalies.

    Introduction Gallbladder duplication is a rare congenital anomaly. Recognition of this anomaly and its various types is important since it can complicate a simple hepatobiliary surgical procedure. Presentation of case We report a case of a 42 year old female who presented a 6 year history of intermittent right upper quadrant abdominal pain. Her basic blood investigations including liver function tests were normal. Pre-operative imaging revealed a cystic lesion communicating with biliary tree representing duplicated gallbladder. She subsequently underwent successful laparoscopic cholecystectomy. The operative challenges were more than those anticipated at the usual laparoscopic gallbladder procedures. After six months follow up the patient remained asymptomatic. Discussion Preoperative diagnosis plays a crucial role in planning surgery, and preventing possible biliary injuries or re-operation if accessory gallbladder has been overlooked during initial surgery. Magnetic resonance cholangiopancreatography (MRCP) is the imaging modality of choice for suspected duplicate gallbladder. Laparoscopic cholecystectomy for duplicate gallbladder is a challenging operation and should be performed with meticulous dissection of the cysto-hepatic triangle. Conclusion Gallbladder anomalies should be anticipated in the presence of a cystic lesion reported around the gallbladder. The laparoscopic cholecystectomy remains feasible for intervention and should be done by an experienced laparoscopic surgeon. PMID:27002289

    Gallbladder cancer is one of the most common cancers of biliary tract with aggressive pathophysiology, now emerging as a global health issue. Although minority of gallbladder cancer patients could receive such curative resection due to late diagnosis, this increases the survival rate. Lack of potential target molecule (s) for early diagnosis, better prognosis and effective therapy of gallbladder cancer has triggered investigators to look for novel technological or high throughput approaches to identify potential biomarker for gallbladder cancer. Intervention of non-coding RNAs in gallbladder cancer has been revealed recently. Non-coding RNAs are now widely implicated in cancer. Recent reports have revealed association of non-coding RNAs (microRNAs or miRNAs and long non-coding RNAs or lncRNAs) with gallbladder cancer. Here, we present an updated overview on the biogenesis, mechanism of action, role of non-coding RNAs, the identified cellular functions in gallbladder tumorigenesis, their prognostic & therapeutic potentials (efficacies) and future significance in developing effective biomarker(s), in future, for gallbladder.

    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.

    Cholecystokinin is the main hormonal regulator of gallbladder motility. Dexloxiglumide, the active enantiomer of loxiglumide, interacts competitively with CCK1 receptors as determined in preclinical studies, such as specific radioligand binding assays or functional studies on isolated guinea pig gallbladder, where it inhibited smooth muscle cell contractions induced by cholecystokinin-octapeptide (CCK-8), the most prominent active forms of cholecystokinin. Dexloxiglumide has a potent antagonistic effect, of a competitive nature, on human gallbladder cholecystokinin type 1 receptors. In isolated human gallbladder, dexloxiglumide produced a concentration-dependent rightward shift of the cholecystokinin-octapeptide curve, without affecting its maximal response. Gallbladder motility was evaluated in clinical studies. Dexloxiglumide, orally administered to healthy volunteers at putative therapeutic doses, did not interfere with post-prandial gallbladder kinetics, despite an increase of fasting gallbladder volume. At present, dexloxiglumide is in an advanced stage of clinical research in gastroenterology. Overall, clinical observations suggest that dexloxiglumide may become an effective treatment in several gastrointestinal disorders. Moreover, the beneficial effects can be obtained without increasing the risk of gallstones formation, a potential hazard subsequent to the inhibition of gallbladder contractions and the resulting bile stasis. The potent and selective antagonist dexloxiglumide may offer a possible therapeutic tool for use not only in functional gastrointestinal disorders, such as irritable bowel syndrome, constipation, gastroesophageal reflux disease and functional dyspepsia, but also in other pathologies, such as biliary colics, pancreatic diseases and gastrointestinal tumors.

    The obesity epidemic has contributed to an increased prevalence of gallstones and a higher percentage of chronic acalculous cholecystitis. Obesity is associated with Type II diabetes and hyperlipidemia in murine models. In addition, we have previously demonstrated that serum glucose, insulin, cholesterol, and triglycerides correlated with gallbladder contractility in murine models. However, the relative role of insulin resistance and gallbladder fat infiltration in this phenomenon remain unclear. Therefore, we tested the hypothesis that gallbladder wall lipids are related to obesity and diet and are inversely correlated with gallbladder contractility. One hundred lean control (C7BL/6J) and 36 obese leptin-deficient (Lep(ob)) 8-week-old female mice were fed either a chow diet or a 1.0% cholesterol, 15% butterfat (high-lipid) diet for four weeks. Pooled gallbladders were then analyzed for free fatty acids (FFA), phospholipids (PL), total cholesterol (TC), and triglycerides (TG). Cholesterol/phospholipid ratios were then calculated. The Lep(ob) mice fed a chow diet had significantly higher (P < 0.01) gallbladder lipids than the three other groups. The lean mice that were fed a high-lipid diet had increased (P < 0.05) gallbladder TC compared to the lean mice on a chow diet. In addition, the cholesterol/phospholipid ratio was significantly increased (P < 0.01) in the lean mice fed a high-lipid diet compared to the other three groups. Finally, the high-lipid diet decreased gallbladder FFA (P < 0.01), PL (P = 0.08), and TC (P < 0.05) in Lep(ob) mice. These data suggest that (1) obese mice have increased gallbladder lipids; (2) a high-cholesterol, high-fat diet increases gallbladder lipids and the cholesterol/phospholipid ratio in lean mice; but (3) decreases gallbladder fatty acids, phospholipids, and cholesterol in obese mice. Prior studies have documented similarly decreased gallbladder response to neurotransmitters in obese mice on a chow diet, as well as lean and

    Gallbladder varices are a rare form of collateralization that develop in patients with portal hypertension. We present here a case of gallbladder varices accurately diagnosed by contrast enhanced CT imaging of the abdomen and confirmed by Color Doppler Sonography. A 76-year-old patient with hepatocellular carcinoma developed portal vein thrombosis due to tumor extension during the course of treatment and was incidentally discovered to have gallbladder varices. While most commonly asymptomatic, gallbladder varices are associated with increased risk of massive bleeding, either spontaneously or during cholecystectomy. As a result, the existence of such varices should be well documented if the patient is to undergo any abdominal surgical procedures. In addition, because of a particular association with portal vein thrombosis, patients with portal hypertension that are found to possess gallbladder varices should be evaluated for portal vein thrombosis.

    Extramedullary plasmacytoma is rare in patients with diagnosed multiple myeloma. Soft tissue plasmacytoma of the gallbladder is particularly uncommon and has been described in only a handful of cases. Diagnosis of gallbladder plasmacytoma with fluorine 18-fluorodeoxyglucose (F18-FDG) positron emission tomography/computed tomography (PET/CT) has not previously been reported. We present a 65-year-old female with a history of multiple myeloma who underwent a restaging F18-FDG-PET/CT which showed a focal area of hypermetabolic activity, corresponding to a nodular lesion within the posterior gallbladder wall. The patient underwent successful cholecystectomy, with surgical pathology revealing gallbladder plasmacytoma. A follow-up scan was negative for active malignancy. This is a novel case of gallbladder plasmacytoma diagnosed on whole-body F18-FDG PET/CT – thus demonstrating the clinical value of this imaging modality in staging, restaging, and surveillance for patients with multiple myeloma.

The results revealed alterations in various tissue lipid components in gallbladder in CC, XGC and GBC. The difference in the nature of lipid components in benign and malignant disease may aid in the identification of the biological pathways involved in the etiopathogenesis of GBC. This is the first study on lipid profiling of gallbladder tissue by (1) H NMR spectroscopy, and has possible implications for the development of future diagnostic approaches. PMID:22945290

    This paper deals with the ultrasonic studies of the effect of artemisia decoction (AD) on the volume and motion of gallbladder in 33 cases. Ultrasonic examination shows that AD intravenous infusion has remarkable effects on the contractility of gallbladder. There are 4 patterns of phasic changes in the motion of gallbladder and an increase in frequency of its contraction and relaxation. AD has also certain contraction effects on the gallbladders which can not contract after a fatty meal. The above findings indicate that AD is a good choleretic and has a definite regulating effect on the motility of the gallbladder. The clinical use of AD is conducive to bile flow, stone expelling, inhibiting the deposition of bile solids and reducing the possibility of stone formation. PMID:8504698

    A photo-optical observation on gallbladder motility was made with the 16 mm cine-cholangiography. The subjects studied were thirty two mongrel dogs. The gallbladder was exposed by a short upper midline abdominal incision under pentothal anesthesia. Gallbladder bile was aspirated and contrast medium was given into the bladder, through a transhepatic route. The cine-cholangiography was done by an image intensifier at a speed of one frame every 2 to 4 seconds. The cinefilms taken were observed repeatedly by the screen projection at various speeds. The drawings were made by tracing the outline of the image of the gallbladder on each frame and were overlapped. Moreover, a contraction curve was made by the cholecystometry using of film motion analyzer in every case. At the same time bile flow into the duodenum was recorded to study a relationship between the gallbladder contraction and motility of the terminal common bile duct. The results obtained are as follows: 1. In a resting state any contraction of the gallbladder was not seen during 30 minutes, and a peristalsis-like movements of the neck portion was observed. However, there was not a relationship between the contraction curve of the gallbladder and the bile flow into the duodenum. 2. Immediately after giving Caerulein, the contrast medium injected into the gallbladder was rapidly discharged into the common bile duct by a peristalsis-like movement of the neck. The size of the gallbladder was markedly decreased into three fifths of the initial state three minutes after administration. At the same time contrast medium was continuously discharged into the duodenum. 3. After giving pilocarpine a marked contraction with forceful movement of the neck and body was observed, and the size of the gallbladder was decreased into three quarters ot the initial state. Bile discharge into the duodenum was markedly increased with an active open- and closing movement of the terminal common bile duct.

    Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer .The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively. Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases). Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma. We also investigated the expression of some known tumor markers such as MIB-1 (anti Ki-67), CD34 and CA15-3, to identify a possible correlation between the expression of these molecular factors and the prognosis of gallbladder carcinoma. They resulted highly expressed in the stroma (CD34 and CA 15-3) and in the epithelium/epithelial glands (MIB-1) of the neoplastic areas and appeared to be almost absent in the control cases, suggesting that these markers, taken together

Here we highlight a case of Terrien Marginal Degeneration in both eyes with atypical presentation; namely pseudopterygium. A 22 year old man was referred to our centre for iatrogenic right eye corneal perforation after having an atypical pterygium removed at another hospital. On arrival, his vision was 1/60 in both eyes with bilateral cornea Terrien Marginal Degeneration. His right eye anterior chamber was deep with a conjunctival flap covering the perforation site which was located from the 2.30 - 3.30 clock position nasally with no aqueous leak. However after a day his right eye anterior chamber became flat and there was fast aqueous leak from the perforation site. An emergency C shaped peripheral corneal lamellar keratoplasty was performed to seal the perforation. Post operatively his right eye improved to 6/24.

    Despite the introduction of histamine H2-receptor antagonists, proton-pump inhibitors and the discovery of Helicobacter pylori, both the incidence of emergency surgery for perforated peptic ulcer and the mortality rate for patients undergoing surgery for peptic ulcer perforation have increased. This increase has occurred despite improvements in perioperative treatment and monitoring. To improve the outcome of these patients, it is necessary to investigate the reasons behind this high mortality rate. In this review we evaluate the existing evidence in order to identify significant risk factors with an emphasis on risks that are preventable. A systematic review including randomized studies was carried out. There are a limited number of studies of patients with peptic ulcer perforation. Most of these studies are of low evident status. Only a few randomized, controlled trials have been published. The mortality rate and the extent of postoperative complications are fairly high but the reasons for this have not been thoroughly explained, even though a number of risk factors have been identified. Some of these risk factors can be explained by the septic state of the patient on admission. In order to improve the outcome of patients with peptic ulcer perforation, sepsis needs to be factored into the existing knowledge and treatment.

Methods and Materials: We retrospectively reviewed the records from consecutive patients who underwent R0 resection of gallbladder carcinoma between January 1, 1985, and December 31, 2004. Patients had either Stage I (T1-T2N0M0) or Stage II (T3N0M0 or T1-T3N1M0) disease. Patients undergoing adjuvant therapy received 5-fluorouracil chemotherapy concurrently with radiotherapy (median dosage, 50.4 Gy in 28 fractions). Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) were evaluated. Results: A total of 73 patients were included in the analysis; of these, 25 received adjuvant chemoradiotherapy. On univariate analysis, no adverse prognostic factors for OS reached statistical significance, but trends were noted for Stage N1 vs. N0 (p = .06), Nx vs. N0 (p = .09), Stage T3 vs. T1-T2 (p = .06), and histologic findings other than adenocarcinoma (p = .13). The median OS for patients receiving adjuvant chemoradiotherapy vs. surgery alone was 4.8 years and 4.2 years, respectively (log-rank test, p = .56). However, a significantly greater percentage of patients receiving adjuvant chemoradiotherapy had Stage II disease (p <.001). In the multivariate Cox model, increasing T and N category and histologic findings other than adenocarcinoma were significant predictors of decreased OS. Additionally, adjuvant chemoradiotherapy was a significant predictor of improved OS after adjusting for these prognostic factors (hazard ratio for death, 0.3; 95% confidence interval, 0.13-0.69; p = .004). Conclusion: After adjusting for the stage parameters and histologic findings, our data suggest that adjuvant chemoradiotherapy might improve OS for patients with gallbladder cancer.

    Establishing a precise duration of gestation is vital in situations such as infanticide and criminal abortions. The present study attempted to estimate the gestational age of the foetus from gall-bladder length. Foetuses of various gestational age groups were dissected, and the length of the gall bladder was measured. The results were analysed, and a substantial degree of correlation was statistically confirmed. This novel method is helpful when the foetus is fragmented, putrefied or eviscerated, where this method can be used as an additional parameter to improve the accuracy of foetal age estimation.

    A case of serrated adenomatous polyp found in a cholecystectomy specimen is reported. The adenoma was built with mucosal crypts exhibiting unlocked serrations lined with up to high-grade dysplastic cells. A desmoplastic sclerotic tissue having multiple stromal hubs with branched thin spokes replaced the subjacent lamina propia, muscularis mucosae, and submucosa. The generous serrated configurations covering a multi-branched sclerotic stroma, gave the adenoma a papillary appearance. Review of the literature indicates that this appears to be the first reported case of serrated adenoma of the gallbladder.

    Laser welding of biliary tissues would be a valuable technique in conventional and endoscopic surgery. Laser welding would allow the avoidance of potentially lithogenic suture material as a sequela to biliary tract surgery. Laser welding would be compatable from the surgical technical standpoint with fiberoptic endoscopic intrumentation. The 2.15 micron thulium-holmium-chromium laser offers tissue penetration on the order of a few hundred microns. We have hypothesized that this laser might be well suited to performing biliary tissue welding. We evaluated this laser in vitro using canine gallbladder tissue and we were able to achieve histologically satisfactory tissue fusion and immediate bursting strengths above physiologically encountered biliary pressures.

    Malignant melanoma has a variety of morphologic patterns and can metastasize and mimic any type of neoplastic process creating significant diagnostic difficulty. When metastasis to the gastrointestinal system is identified, it is most commonly associated with widely metastatic disease. We report a rare case of isolated gallbladder intramucosal metastatic melanoma with features mimicking lymphoepithelial carcinoma in an adult patient who presented with cholecystitis. Additionally, we report the imaging and morphologic features and discuss the importance of these findings along with a clear clinical history and immunohistochemical profile to make a definitive diagnosis.

    Computer tomography of the kidneys was performed on 30 patients with acute renal infections (acute suppurative pyelonephritis, acute renal abscess, infected cyst, pyelonephrosis, calculus perforation, retroperitoneal abscess). Computer tomography provided more accurate information concerning the extent of the renal and extra-renal inflammatory process than did the urogram or sonogram. This may significantly affect the choice of treatment, particularly concerning the use of drugs or of surgery. Angiography and retrograde pyelography may be used in selected cases, especially where there is a suspicion of acute bacterial nephritis, renal vein thrombosis or ureteric obstruction.

    Abstract The incidence of pediatric acute inflammatory gallbladder (GB) disease without gallstone such as acute acalculous cholecystitis has increased with the development of improved diagnostic modalities. Although Epstein–Barr virus (EBV) infection is common in general population, only few cases of GB diseases caused by EBV infection have been reported. This study analyzed ultrasonographic characteristics of primary EBV infection in children and evaluated the influence of EBV-associated GB disease on clinical course and outcome of EBV infection. Between March 2004 and January 2013, 94 of 287 pediatric patients with EBV infection underwent abdominal ultrasonography (USG); clinical features, laboratory data, and USG findings were collected and analyzed retrospectively. Of 94 children, ultrasonographic thick GB wall was observed in 24 (25.3%). Platelet counts were lower in the thickened GB wall group than in the normal GB wall thickness group (P = 0.004). Direct bilirubin, alanine aminotransferase, and γ-glutamyl transferase levels were higher in the thickened GB wall group (P = 0.000, P = 0.041, and P = 0.001, respectively). The duration of hospitalization was longer in patients with thickened GB wall (P = 0.043). Radiologic findings of acute acalculous inflammatory GB disease such as thickened GB wall caused by primary EBV infection are more common than previously reported. Consideration of EBV infection in the differential diagnosis of children suspected with acute acalculous GB diseases may avoid unnecessary surgical intervention. PMID:26166109

    This paper shows that the oriented-perforation technique is an effective method to control casing collapse problems for highly inclined wells. Three wells were perforated with 180{degree} phasing in the maximum in-situ stress direction. These three wells did not experience casing collapse, while surrounding wells with the standard perforation technique did. Two of the three wells with oriented perforations experienced significantly reduced sand problems. Numerical analysis was conducted to compare how effective orient perforations were in minimizing casing failure when a sheared zone was created around a well during drilling and production.

    Because mucin glycoproteins may be important in the pathophysiology of gallstones, we studied the relationship among biliary lipids, gallbladder mucin secretion, and gallstone formation in cholesterol-fed prairie dogs. Organ culture studies of gallbladder explants revealed that the incorporation of [3H]glucosamine into tissue and secretory gallbladder glycoproteins was significantly increased at 3, 5, 8, and 14 d of feeding. Peak secretion of labeled mucin occurred at 5 d, when total tissue and secreted glycoprotein production was fivefold greater than control. Gel filtration of the secreted glycoprotein on Sepharose 4B indicated that the majority of radioactivity was present in a macromolecule of > 1 million molecular weight. The increased secretion of gallbladder mucin was organ specific, in that [3H]glucosamine incorporation into glycoproteins of stomach and colon was unaffected by cholesterol feeding. Similarly, the incorporation of [3H]mannose into gallbladder membrane glycoproteins was not altered by cholesterol feeding. The rate of glycoprotein synthesis and secretion returned to normal upon withdrawal of the cholesterol diet, and ligation of the cystic duct before cholesterol feeding prevented gallbladder mucin hypersecretion. Both results indicate that the stimulus to mucin secretion was a constituent of bile. Gallbladder bile after 5 d contained cholesterol in micelles, liquid crystals, and crystals, whereas hepatic bile remained a single micellar phase throughout cholesterol feeding. For this reason the cholesterol-saturation indices of gallbladder bile were compared in both homogenized and centrifuged samples. The micellar phase of gallbladder bile was appreciably less saturated than homogenized bile at 5 and 8 d, which reflects the continuous nucleation of cholesterol in the gallbladder. Purified human gallbladder mucin gels were shown to induce nucleation of lecithin-cholesterol liquid crystals from supersaturated hepatic bile. These in turn gave rise

    HMGB1 (High mobility group box 1) expressions in adenocarcinoma (AC) and squamous cell/adenosquamous (SC/ASC) carcinoma of gallbladder, as well as its prognostic significance, have not yet been evaluated. We investigated HMGB1 expression in 80 cases of AC gallbladder cancer and 52 cases of SC/ASC gallbladder cancer. Survival information was concomitantly collected. The association of HMGB1 expression with clinicopathological characteristics and the possible prognostic role of HMGB1 for two aforementioned subtypes of gallbladder cancers were also analyzed. siRNA technique was utilized to explore the role of HMGB1 in proliferation and invasion of gallbladder cancer cells in vitro. HMGB1 overexpression is present in AC and SC/ASC gallbladder cancers. HMGB1 expression significantly associates with growth and metastasis of AC and SC/ASC gallbladder cancers. In vitro cell experiments based on siRNA demonstrated that HMGB1 downregulation inhibits proliferation and invasion of gallbladder cancer cells. Kaplan-Meier analysis revealed that HMGB1 expression is negatively associated with overall survival time of patients with AC or SC/ASC gallbladder cancer. Cox multivariate analysis confirmed that HMGB1 is an independent risk factor for survival of patients with AC or SC/ASC gallbladder cancer. HMGB1 overexpression closely correlates with progression and poor prognosis of AC and SC/ASC gallbladder cancers. PMID:26692945

    Acute pancreatitis during pregnancy is a serious condition and diagnosis is often difficult. The authors report the case of a 32-year-old woman in the 32nd week of her fifth pregnancy, in which the outcome was fatal for both mother and child. The cause of pancreatitis during pregnancy has been attributed to many factors, chiefly cholelithiasis. A number of recent studies have shown the relationship existing between the role played by pregnancy in predisposing to gallbladder disease with lithiasis. Many diagnosis errors are made in this condition. Thus modern treatment methods have improved the prognosis in acute pancreatitis but, when it occurs during pregnancy, diagnostic delays often lead to a gloomy outlook. PMID:8248696

    Gallbladder filling was studied using computer-assisted cholescintigraphy in normal subjects who had fasted overnight. The gallbladder tended to visualize earlier than the distal part of the common bile duct. It appeared at approximately the same time regardless of whether or not there was passage of activity into the duodenum. This suggests that filling is not dependent on contraction of the sphincter of Oddi. Sequential images demonstrated that the activity entering the gallbladder rapidly reached the fundus. Time-activity curves showed a gradual buildup of activity in the bile ducts followed by sudden entrance into the gallbladder. Time-activity curves of the gallbladder's proximal and distal parts showed signs of an exchange of activity, suggesting that the gallbladder's motor function is not quiescent during fasting. Gallbladder motility could explain the periodic irregularities on the time-activity curve. These irregularities were smaller but no less frequent after morphine administration.

    Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90%) perforations are solitary. Herein, we describe a case of a 25-year-old male who presented with generalized peritonitis requiring an emergency exploratory laparotomy, which revealed pan-enteric perforation characterized by multiple perforations of the small bowel extending 10–15 cm from the DJ flexure up to the terminal ileum. The perforations were primarily closed, while 6–8 cm of the diseased terminal ileum was resected and the two ends were brought out as double-barreled ostomy. To the best of our knowledge, such an extensive tuberculous perforation of the small bowel has not been previously reported in the literature before. PMID:26798540

    Background Ulcer perforation carries up to a 30% 1-year mortality rate. Intervention-related adverse events are among statistically significant predictors of 1-year mortality. A Natural Orifice Transluminal Endoscopic Surgical (NOTES) approach may be less invasive and may decrease procedure-related adverse events by diminishing the "second hit", thus leading to decreased morbidity and mortality. Aim To assess the feasibility of an endoscopic transluminal omental plug technique in patients with perforated gastroduodenal ulcers under laparoscopic guidance. Methods Patients with suspected acute gastroduodenal ulcer perforations were offered participation in this prospective pilot study. Closure of the perforation was attempted using NOTES omental plug technique. Demographic, clinical, endoscopic and radiographic data were abstracted, as well as morbidity, mortality and pilot data regarding quality of life (QOL). Results From February 2010 through Feb 2012, 17 patients presented to a tertiary care center with clinically suspected perforated ulcer. Of seven patients (mean age 79, range 64–89) who consented to the study, three underwent the study procedure. All patients had multiple comorbidities. Two patients presented with 4–6 mm perforated peptic ulcers and underwent successful laparoscopic-assisted NOTES omental and falciform ligament patch closure, respectively. Postoperative radiographic contrast studies showed no leak and patients were discharged home on postoperative days 3 and 4. The third patient had undergone enterocutaneous fistula repair with herniorrhaphy 6 weeks prior; a transluminal endoscopic approach was feasible; however, the omentum was under too much tension to be secured. This procedure was converted to an open omental patch repair. For all but one consented patient, obtaining QOL data was feasible. Conclusion Initial results from a laparoscopic-assisted NOTES approach for closure of perforated peptic ulcers appear promising and enable swift

    AIM: To identify risk factors of actual appendiceal perforation when computed tomography (CT) scans suggest nonperforated appendicitis and accordingly determine surgical priority. METHODS: We collected database of 1362 patients who underwent an appendectomy for acute appendicitis between 2006 and 2013. A single radiologist selected 1236 patients whose CT scans were suggestive of nonperforated appendicitis. Patients were divided into 2 groups: actual nonperforation group and actual perforation group according to intraoperative and pathologic features. Comparison of the 2 groups were made using binary logistic regression. RESULTS: Of 1236 patients, 90 (7.3%) were found to have actual appendiceal perforation. Four risk factors related with actual appendiceal perforation were identified: body temperature ≥ 37.6  °C (HR = 1.912, 95%CI: 1.161-3.149; P = 0.011), out-of-hospital symptom duration ≥ 72 h (HR = 2.454, 95%CI: 1.292-4.662; P = 0.006), age ≥ 35 years (HR = 3.358, 95%CI: 1.968-5.728; P < 0.001), and appendiceal diameter on CT scan ≥ 8 mm (HR = 4.294, 95%CI: 1.034-17.832; P = 0.045). Actual appendiceal perforation group showed longer operation time, later initiation of diet, longer use of parenteral narcotics, longer hospital stay, and higher incidence of postoperative complications (P < 0.05). CONCLUSION: We proposed here new criteria to select patients with adverse clinical outcomes after appendectomy among the patients with radiologically nonperforated appendicitis. Surgical appendectomy outcomes could be improved by determining the surgical priority according to our criteria. PMID:25717248

    Introduction The mainstay of treatment for perforated peptic ulcer is Omental patch closure. With the advent of laparoscopic surgery, this approach is being used for the treatment of perforated peptic ulcer. The aim of this study was to evaluate the outcome of laparoscopy in Firoozgar general hospital over a period of 18 months. The outcome of the laparoscopic approach and the associated morbidity and mortality, operation time, conversion rate and hospital stay were assessed. Methods A prospective analysis of 29 consecutive patients (mean age 37.5 years; 23 men) with perforated peptic ulcers and who had undergone laparoscopic surgery was carried over a period of 18 months from March 2014 until September 2015. Pre-operative, intra-operative, and post-operative clinical data were collectively analyzed by SPSS 19 for Windows. Results Seventeen patients had a history of cigarette smoking, 11 patients had a history of opium consumption, 19 were chronic NSAID users, 26 had Helicobacter pylori infections, and six had a co-morbid condition. Previous surgical history included laparotomy for pancreatic cancer in two patients, for sigmoid colon cancer in one patient, and for acute appendicitis in four patients. The average operating time for all cases was 47.5 + 20 min. The mean lag time between onset of symptoms and surgery was 20.4 hours. All patients underwent laparoscopic closure of the perforation with Omental patch closure. No morbidity was observed, and none of the patients needed conversion to open surgery. One patient died after 11 months of follow-up due to the progression of underlying pancreatic cancer. The mean postoperative hospital stay was 4.2 days. Conclusions The results of the laparoscopic approach for perforated peptic ulcer were promising, with no conversion to open surgery, no morbidity, and mortality. PMID:27504170

    The main objective of this study is to assess the feasibility and safety of treating hepatocellular carcinoma (HCC) proximal to the gallbladder using laparoscopic radiofrequency ablation (RFA). Surgical ablation of tumor located adjacent to the gallbladder may damage the gallbladder wall, even with a laparoscope and this ablation method is not precise and incomplete and is frequently combined with alcohol injections with need for further RFA treatment. Four patients were included in this study, with typical HCC where the tumor was present on the left, right, or bed side surrounding the gallbladder. The gallbladder was not separated or removed during larascopic inspection. In the RFA treatment procedure, the tumor lesion was pre-heated for 10 min, and heating was continued for 20 min. The integrity of the gallbladder wall was properly maintained. A follow-up to check for possible local recurrence was carried out 1 year after the RFA. The goal of "one-off" tumor complete RFA is to achieve thorough ablation of the tumor in a single treatment and limiting the possibility of recurrence within 6 months. Seven days after RFA, liver functions of all the patients returned to near-preoperative levels. The patients experienced slight pain in the upper right abdomen, which disappeared in 2-3 days. Results of B ultrasound on days 3-5 showed thickening of the periphery of the ablation area, without significant effusion. Enhanced CT on day 3 showed that RFA low-density area completely covered the lesions. No significant abnormality was observed in the gallbladder and its vicinity. One month after the surgery, B ultrasound and CT examination revealed no significant abnormalities. All patients had an intact gallbladder, and no extrahepatic or intrahepatic bile duct dilatation occurred. There was no evidence of damage to the bile duct or the vessels. Follow-up for 18-32 months found that all patients were in good condition. "One-off" complete RFA can be safely implemented to ablate

    A 58-year-old woman presented to a tertiary care centre with signs and symptoms of acute cholecystitis, cholelithiasis and diagnoses of a high-grade neuroendocrine tumour of the gallbladder primarily with peritoneal and liver metastases. She had a liver abscess secondary to Salmonella and Enterococcus fecalis that was drained and treated with appropriate antibiotics. Interestingly, the serum chromogranin A levels were within normal limits, but carcinoembryonic antigen was elevated, which helped evaluate responses and pick progression. She was treated with 10 cycles of palliative chemotherapy when malignancy associated complications started to recur, that is, cholangitis, worsening pain, cachexia, intestinal obstruction, etc leading to chemotherapy delays. Her disease progressed during these times with rapid deterioration of performance status. She died of septic complications postlaparotomy for intestinal obstruction. Her progression-free survival remained for 8 months with subjective and objective improvements, and her overall survival remained at 13 months. We describe the course of her illness and give a brief review of the literature. PMID:23661652

This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. Case Presentation This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery. Conclusions It is of a great importance to closely monitor the therapy compliance of patients suffering from mental illnesses. This will benefit them by preventing some of the serious complications of their disease, which may include life-threatening conditions such as intestinal perforation that needs surgical intervention.

    ABSTRACT BACKGROUND: Clinical significance of sex hormone receptors in gallbladder cancer is not yet established. This study was performed to assess the expression pattern of estrogen and progesterone receptors in benign and malignant gallbladder lesions, and to assess their clinicopathological significance. METHODS: Tissue samples from resected gallbladder for cholelithiasis (n = 20) and carcinoma gallbladder (n = 25) were evaluated for estrogen and progesterone receptor (ER, PR) expression by automated immunohistochemistry. Their expression was correlated with different clinicopathological parameters. RESULTS: ER expression was significantly high (28%, 95% confidence interval [CI], 14–47) in gallbladder cancer than in chronic cholecystitis (0%; P = .012). PR expression did not differ in two groups (benign 40%, 95% CI, 21.8–61.4; malignant 52%, 95% CI, 33.5–69.9). Metaplastic benign lesions had near significant higher expression of PR (71.4%) than nonmetaplastic lesion (15.9%; P = .062). Their expression did not correlate with gender, age, menopausal status, presence of gallstones, tumor differentiation, and tumor stage. CONCLUSION: Female sex hormones play an important role in the gallbladder carcinogenesis. ER and PR may not have prognostic value. Presence of ER in ∼1/3 and PR in 1/2 of patients with carcinoma gallbladder suggests the potential role of antihormonal therapy. PMID:22690257

    In the current study, we examined the potential effect of Ginsenoside Rg3 against gallbladder cancer cells, the underlying signaling mechanisms were also studied. We demonstrated that Rg3 exerted potent cytotoxic and pro-apoptotic activity against established and primary human gallbladder cancer cells. Yet it was safe to non-cancerous gallbladder epithelial cells. At the molecular level, we showed that Rg3 induced endoplasmic reticulum (ER) stress activation, the latter was evidenced by C/EBP homologous protein (CHOP) upregulation, inositol-requiring enzyme 1 (IRE1)/PKR-like endoplasmic reticulum kinase (PERK) phosphorylations, and caspase-12 activation in gallbladder cancer cells. Reversely, the ER stress inhibitor salubrinal, the caspase-12 inhibitor z-ATAD-fmk as well as CHOP shRNA knockdown significantly attenuated Rg3-induced cytotoxicity against gallbladder cancer cells. In vivo, we showed that Rg3 oral administration significantly inhibited GBC-SD gallbladder cancer xenograft growth in nude mice, its activity was, however, compromised with co-administration of the ER stress inhibitor salubrinal. Thus, we suggest that ER stress activation mediates Ginseng Rg3-induced anti-gallbladder cancer cell activity in vitro and in vivo. PMID:26361144

    Three-dimensional (3D) ultrasonography has been shown to be an accurate and appropriate tool for measurement of gallbladder volume in humans. Therefore, we applied this novel technique for the first time to study fasting and postprandial gallbladder volume in 10 healthy dogs and compared the results with those of 2-dimensional (2D) ultrasonography. Fasting gallbladder volumes determined by 3D ultrasonography were significantly higher than corresponding volumes determined by 2D ultrasonography (P<0.01). Additionally, gallbladder volumes were significantly decreased in the postprandial state compared with the fasting state using 3D ultrasonography (P<0.001), but 2D ultrasonography showed no significant difference (P=0.189). The Gallbladder contraction index was higher in 3D ultrasonography than 2D ultrasonography; however, it did not reach statistical significance (P=0.25). In conclusion, 3D ultrasonography was able to measure gallbladder volume in healthy dogs in this study. It is suggested that 3D ultrasonography can be used to accurately estimate gallbladder volume and contractility.

    Prairie dogs were fed a 1.2% cholesterol diet for up to 24 weeks to evaluate the effects of lithogenic bile on the mucosa of the gallbladder. There was a progressive increase in the lithogenic index of the gallbladder bile (1.44 +/- 0.15 at 4 weeks, p less than 0.05). Fifty-five of 70 animals developed gallstones between the second and fourth week. Increasing stone burden was associated with a 27% (p less than 0.05) decrease in the electrical resistance of the epithelium and a 60% (p less than 0.05) decrease in net sodium transport when measured isotopically in an Ussing chamber (3 weeks). After 4 months, seven of ten animals developed inflammatory mucosal polyps characterized by a heavy infiltration of plasma cells into an expanded matrix. Cellular infiltration began as early as 2 weeks. These changes occurred without alterations in the ultrastructural appearance of the epithelium. Images Figs. 3A and B. Figs. 4A and B. Figs. 4A and B.

    Hydrocephalus is a frequently encountered problem in infancy and is most commonly treated by placement of ventriculoperionteal (VP) or ventriculoatrial (VA) shunts. Other sites for insertion of the distal shunt have included the stomach, ureter, and fallopian tube. This report describes an experience with ventricular gallbladder shunts (VGB) in 25 children performed from 1970 to 1985. There were 13 girls and 12 boys ranging in age from 6 months to 16 years. Diagnosis included meningomyelocoele (7), congenital hydrocephalus (7), postmeningitic complications (5), intracranial tumor (4), and intraventricular hemorrhage (2). Indications for operation included VP shunt infection (15), massive ascites following VP shunt (3), VA shunt infection (4), and distal shunt malfunction due to fibrinous adhesions or cysts (secondary to infection; (3). Three patients had early shunt failure due to proximal obstruction (2) and gallbladder atony (1). Shunt revision was required in two and the atony was successfully treated with cholecystokinin in one. Fourteen shunts remain in place, two patients have been lost to follow-up, and three children died from unrelated causes. Seventy percent of the 20 patients available for long-term follow-up have functional shunts in place. The VGB shunt procedure remains an attractive alternative for patients with hydrocephalus in whom intraperitoneal and intravascular shunts are no longer feasible.

    Laparoscopic cholecystectomy is widely accepted nowadays as the gold standard in the treatment of cholelithiasis. This new technique was initially associated with a significant increase in morbidity, and in particular in iatrogenic biliary injuries and arterial haemorrhages, perhaps due to a lack of knowledge of the "laparoscopic anatomy" of the gallbladder pedicle. In this technique the anatomical structures are viewed on a two-dimensional video monitor, and the dissection is performed with long instruments without manual sensitivity. Therefore, the laparoscopic surgeon has to deal with new anatomical views and must be aware of the possible arterial and biliary variants. In this review we describe our technique of laparoscopic cholecystectomy, with particular reference to manoeuvres useful for identifying the various anatomical structures at the gallbladder hilum. In our opinion, it is mandatory to avoid cutting any duct if its identity has yet to be established. For this reason, we pay great attention to the anatomical dissection of Calot's triangle, in order to accurately identify the cystic duct and the cystic artery and any other vascular or biliary structures. Routine intraoperative cholangiography may be useful for identifying the biliary anatomy. When in doubt, the surgeon should not hesitate to convert the procedure to open surgery.

    Gallbladder cancer (GBC) is an aggressive malignancy usually diagnosed in an advanced stage. We investigated the effects of alterations of the phosphatase and tensin homologue (PTEN) gene on the occurrence and development of GBC, which has not been previously reported. A total 141 cases of GBC were analyzed for mutation, expression, and methylation across the nine exons of the PTEN gene. DNA sequencing methods were applied for mutation detection, whereas protein expression and methylation status were evaluated by immunohistochemical and methylation-specific PCR analysis, respectively. Novel PTEN mutations were observed in 6.3% of cases (9/141), and they included two silent mutations. In mutant cases, according to changes in codons, the respective amino acid sequences were also changed, which caused of proteins. A high percentage (72%) of loss of protein expression was observed more often in cases than in control samples. Interestingly, all nine cases with mutations showed loss of PTEN expression, whereas four of these nine cases showed positive promoter methylation. Hypermethylation was significantly more common in older patients than in younger ones (P<0.02). These findings suggest that PTEN mutations and inactivation may play an important role in the development and progression of gallbladder carcinoma. PMID:26586294

    Breast cancer is the most frequently diagnosed cancer in women, with an estimated 231,840 new cases representing 14.0% of all new cancer cases in the United States in 2015. Early screening and modern techniques of imaging and diagnosis have led to a significant improvement in detecting early-stage breast cancers and to a decrease in the incidence of metastatic breast cancer (MBC). About 20%-30% of patients who are initially diagnosed with an early-stage, nonmetastatic breast cancer will subsequently develop a distant metastatic disease. Between 6%-10% of the new breast cancer cases present initially as stage IV, referred to as de novo MBC. The most common sites of breast cancer metastases are lymph nodes, chest wall, skeleton, lung, skin, and the central nervous system (CNS). Lobular carcinoma, in particular, may metastasize to the gastrointestinal tract, peritoneum, and retroperitoneum. Gallbladder metastasis from breast cancer is very rare, and only 15-20 cases have been reported in the literature. Most of those cases have been associated particularly with a lobular histology. We report an additional rare case of MBC to the gallbladder, but with a ductal histology. PMID:26270542

    Thyroid storm is a rare and life-threatening complication of thyrotoxicosis that requires prompt treatment. Thyroid storm is also known to be associated with precipitating events. The simultaneous treatment of thyroid storm and its precipitant, when they are recognized, in a patient is recommended; otherwise such disorders, including thyroid storm, can exacerbate each other. Here we report the case of a thyroid storm patient (a 55-year-old Japanese male) complicated with a perforated duodenal ulcer. The patient was successfully treated with intensive treatment for thyroid storm and a prompt operation. Although it is believed that peptic ulcer rarely coexists with hyperthyroidism, among patients with thyroid storm, perforation of a peptic ulcer has been reported as one of the causes of fatal outcome. We determined that surgical intervention was required in this patient, reported despite ongoing severe thyrotoxicosis, and reported herein a successful outcome.

    Ceftriaxone, a third-generation cephalosporin, is partially excreted into bile. With its clinical use, the formation of gallbladder sludge detected by ultrasonography has been reported. Four surgical specimens were examined and no gallstones were found. Instead, fine precipitates of 20-250 microns were present. Microscopically, there was a small number of cholesterol monohydrate crystals and bilirubin granules among an abundant amount of granular-crystalline material that was not morphologically cholesterol monohydrate crystals. The chemical composition of the precipitates (n = 4) was determined. There was a small amount of cholesterol (1.7% +/- 0.8%) and bilirubin (13.9% +/- 0.74%). The major component of the precipitate was a residue. On further analysis using thin-layer chromatography, high-performance liquid chromatography, and electron microprobe analysis, the residue was identified as a calcium salt of ceftriaxone. The residue also had identical crystal morphology and chromatographic elution profile as authentic calcium-ceftriaxone standards. It is concluded that ceftriaxone, after excretion and being concentrated in the gallbladder bile, can form a precipitate. The major constituent has been identified as a ceftriaxone-calcium salt.

    Ingestion of liquid nitrogen is rare but carries catastrophic complications related to barotrauma to the gastrointestinal tract. We describe a case of ingestion of liquid nitrogen followed by gastric perforation and respiratory insufficiency and discuss the mechanism of injury and management of this condition. Liquid nitrogen is widely available and is frequently used in classroom settings, in gastronomy, and for recreational purposes. Given the potentially lethal complications of ingestion, regulation of its use, acquisition, and storage may be appropriate.

    Dengue fever (DF) with acute acalculous cholecystitis is rarely reported. To investigate the incidence, treatment, and prognosis of acute acalculous cholecystitis in DF patients, we retrospectively studied 10 patients with DF and acute acalculous cholecystitis. From October 2001 to July 2002, 131 patients were diagnosed with DF. Ten of 131 DF patients (7.63%) had complications of acute acalculous cholecystitis. Two patients underwent cholecystectomy and one underwent percutaneous transhepatic gallbladder drainage due to poor resolution of acute acalculous cholecystitis. We found acute acalculous cholecystitis in a small proportion of patients with DF. In our experience, closely monitoring vital signs to avoid shock and correct thrombocytopenia to avoid bleeding could be adequate for most patients. In some cases, surgical treatment may be needed for DF fever patients with complications of diffuse peritonitis.

    This report discusses fourteen tests which were conducted to investigate the perforation of thin unreinforced concrete slabs. The 4340-steel projectile used in the test series is 50.8 mm in diameter, 355.6 mm in length, has a mass of 2.34 kg. and an ogive nose with caliber radius head of 3. The slabs, contained within steel culverts, are 1.52 m in diameter and consist of concrete with a nominal unconfined compressive strength of 38.2 MPa and maxima aggregate size of 9.5 mm. Slab thicknesses are 284.4, 254.0, 215.9 and 127.0 mm. Tests were conducted at impact velocities of about 313 m/s on all slab thicknesses and about 379 and 471 m/s on the 254.0-mm-thick slab. All tests were conducted at normal incidence to the slab. All tests were conducted at normal incidence to the slab. Information obtained from the tests used to determine the loading (deceleration) on the projectile during the perforation process, the velocity-displacement of the projectile as it perforated the slab, and the projectile position as damage occurred on the backface of the slab. The test projectile behaved essentially as a rigid body for all of the tests.

    The classic analytical model for the sound absorption of micro perforated materials is well developed and is based on a boundary condition where the velocity of the material is assumed to be zero, which is accurate when the material vibration is negligible. This paper develops an analytical model for finite-sized circular micro perforated membranes (MPMs) by applying a boundary condition such that the velocity of air particles on the hole wall boundary is equal to the membrane vibration velocity (a zero-slip condition). The acoustic impedance of the perforation, which varies with its position, is investigated. A prediction method for the overall impedance of the holes and the combined impedance of the MPM is also provided. The experimental results for four different MPM configurations are used to validate the model and good agreement between the experimental and predicted results is achieved. PMID:26827008

    A case-control study of gallbladder cancer was conducted with 90 Chilean cases registered at one hospital in Santiago city, Chile from January, 1992 to August, 1994. Controls were selected among outpatients of the hospital who received abdominal echography. Each case was assigned 2 age- and sex-matched controls; either with or without gallstone(s). Study subjects were all directly interviewed by well-trained medical students. The present study focused on 74 female pairs and the following findings were obtained: 1) Odds Ratio(OR)s were significantly high for education years less than or equal to 6, body mass index greater than or equal to 24.0, constipation, and consumption of egg, fried meals, green and red chili. Chili pepper consumption of both types in cases showed significantly elevated risks with higher frequency. 2) While high ORs were observed, biliary symptoms such as dyspepsia and past history of cholelithiasis were strongly involved with present gallstone(s) and may not be independent factors for gallbladder cancer. 3) Significantly low ORs were seen for past history of intestinal parasitosis and surgical operation, hormone therapy, all industrial workers and workers in clothes & textile industry. However results may be influenced by more years of education or recall bias. 4) When a conditional logistic model was applied and controls with gallstone(s) were taken as reference, those with the habit of constipation showed a significantly high risk of 2.10 (95% CI: 1.01-4.38), and the consumers of red chili with a frequency > or = 1 time/day had elevated risks of 2.16 (1.27-3.66) vs those < 1 time/day and 4.66 (1.63-13.40) vs non-consumers, respectively. From the above results, the occurrence of gallbladder cancer in Chilean females may be related to constipation and chili pepper consumption, based on the presence of gallstone(s). Further investigations are needed to elucidate whether these are actual risk factors or whether only a false association was

    Leptospirosis, a disease acquired by exposure to contaminated water, is characterized by fever accompanied by various symptoms, including abdominal pain. An acute febrile illness occurred in athletes who participated in an Illinois triathlon in which the swimming event took place in a freshwater lake. Of 876 athletes, 120 sought medical care and 22 were hospitalized. Two of the athletes had their gallbladders removed because of abdominal pain and clinical suspicion of acute cholecystitis. We applied an immunohistochemical test for leptospirosis to these gallbladders and demonstrated bacterial antigens staining (granular and filamentous patterns) around blood vessels of the serosa and muscle layer. Rare intact bacteria were seen in 1 case. These results show that leptospirosis can mimic the clinical symptoms of acute cholecystitis. If a cholecystectomy is performed in febrile patients with suspicious environmental or animal exposure, pathologic studies for leptospirosis on formalin-fixed, paraffin-embedded tissues may be of great value.

    Melanoma is one of the most aggressive and highly metastatic cancers. The most common sites of distant metastases are soft tissues, lung, liver, skin and brain, whereas only few patients develop gastrointestinal metastases. Metastatic involvement of the gallbladder is rare and more often part of a widespread disease than a solitary lesion. The "gold-standard" treatment of metastatic melanoma of the gallbladder remains unclear. We report two cases of patients with past history of cutaneous melanoma who developed visceral metastases. The first patient was asymptomatic and had a widespread disease with metastatic involvement of both the spleen and the gallbladder. The second patient had an isolated metastasis of the gallbladder and complained of upper abdominal pain. The chosen treatment was open cholecystectomy (and splenectomy) in the first case and laparoscopic cholecystectomy in the second. A review of the literature is provided. PMID:25929736

    The effects of extracorporeal spark-gap shockwave lithotripsy (ESWL) on human gallbladder-morphology are barely known. We studied the gallbladders of nine patients cholecystectomized 5 to 166 days after ESWL. Patients were treated one to three times receiving a mean of 1928 +/- 693 shockwaves per treatment, with a total of 3375 +/- 1307 per patient. Control gallbladders were of randomly selected patients after plain cholecystectomy (age and sex-matched). There was no difference in pathomorphology of the two groups. No signs of trauma related damage (hemorrhage, necrosis, ulceration, scar, or hemosiderin deposits) other than from surgical manipulation were found. Predominant pathomorphological changes were signs of chronic cholecystitis due to gallstone disease. In conclusion, spark-gap ESWL did not induce deleterious morphological damage to the gallbladder, although large numbers of shock waves were applied.

    Ciliated foregut cysts are rare anomalies due to aberrant embryological development. Only a small number of gallbladder ciliated foregut cysts have been reported. We report the case of a 29-year-old woman presenting with epigastric pain associated with diarrhoea and vomiting, who was found to have raised serum bilirubin levels and abnormal liver function tests. Following a diagnostic pathway including abdominal ultrasound, magnetic resonance cholangiopancreatography and endoscopic ultrasound the gallbladder cyst was provisionally diagnosed to be a cyst arising from the cystic duct or a duplicated gallbladder. A laparoscopic cholecystectomy was carried out and histopathology identified a ciliated foregut gallbladder cyst. The postoperative course was uneventful. In this report we offer what we believe to be an optimal diagnostic pathway and therapeutic strategy for this rare congenital cyst.

    A case history of patient with a abnormal gallium uptake and sonogram in the region of the gallbladder is described. The abnormality was interpreted as empyema of the gallbladder and later proven surgically. A liver-spleen scan was normal except for slight prominence of the hilar structures. Gallium citrate Ga-67 scans done at 24 and 48 hours showed a persistent area of increased tracer localization around the gallbladder with a central clear zone in the latter scan. Ultrasonography revealed poor definition and slight thickening of the gallbladder wall. Because of the lack of specificity of gallium scans, the combination of ultrasonic imaging and gallium uptake scans appears much superior in diagnostic efficiency than either of the two alone. The sequence of performing these two examinations does not seem to be critical though it was prefered that the scintigraphy precede the sonography.

    In early embryogenesis, the posteroventral foregut endoderm gives rise to the budding endodermal organs including the liver, ventral pancreas and gallbladder during early somitogenesis. Despite the detailed fate maps of the liver and pancreatic progenitors in the mouse foregut endoderm, the exact location of the gallbladder progenitors remains unclear. In this study, we performed a DiI fate-mapping analysis using whole-embryo cultures of mouse early somite-stage embryos. Here, we show that the majority of gallbladder progenitors in 9-11-somite-stage embryos are located in the lateral-most domain of the foregut endoderm at the first intersomite junction level along the anteroposterior axis. This definition of their location highlights a novel entry point to understanding of the molecular mechanisms of initial specification of the gallbladder.

    A 68-year-old female with colorectal cancer developed a metachronous isolated fluorodeoxyglucose-avid (FDG-avid) segment 5/6 gallbladder fossa hepatic lesion and was referred for percutaneous ablation. Pre-procedure computed tomography (CT) images demonstrated a distended gallbladder abutting the segment 5/6 hepatic metastasis. In order to perform ablation with clear margins and avoid direct puncture and aspiration of the gallbladder, cholecystokinin was administered intravenously to stimulate gallbladder contraction before hydrodissection. Subsequently, the lesion was ablated successfully with sufficient margins, of greater than 1.0 cm, using microwave with ultrasound and FDG PET/CT guidance. The patient tolerated the procedure very well and was discharged home the next day.

The first part was designed to evaluate accuracy of sonographic measurements in 40 patients on whom intraoperative measurements of wall thickness were obtained. Second, the significance of wall thickness as an indicator of disease was explored by comparing the 40 surgical patients and 44 controls. Sonography was found to be accurate in determining wall thickness to within 1 mm in 93% of patients and 1.5 mm in 100%. Wall thickness greater than 3.5 mm is highly accurate in predicting disease; however, a wall thickness 3 mm or less does not rule out cholecystitis. PMID:6768264

    Hepatic infarction is known as a rare disease entity in nontransplant patients. Although a few cases of hepatic infarction have been reported to be linked with invasive procedures, trauma, and hypercoagulability, a case of spontaneous hepatic infarction in a nontransplanted patient has hardly ever been reported. However, many clinical situations of patients with cancer, in particular biliary cancer, can predispose nontransplant patients to hepatic infarction. Besides, the clinical outcome of hepatic infarction in patients with cancer can be worse than in patients with other etiologies. As for treatment, anticoagulation treatment is usually recommended. However, because of its multifactorial etiology and combined complications, treatment of hepatic infarction is difficult and not simple. Herein, we report a case of fatal hepatic infarction that occurred spontaneously during the course of treatment in a patient with gallbladder cancer. Hepatic infarction should be considered as a possible fatal complication in patients during treatment of biliary malignancies. PMID:27462232

    Vascular variations in and around the porta hepatis are common. A sound knowledge of possible variations at these sites is vital for surgeons during laparoscopic cholecystectomy and surgical resection of the liver lobes. We report the case of several variations of the hepatic and cystic arteries in which, the common hepatic artery trifurcated into the gastroduodenal, right hepatic, and left hepatic arteries. The right gastric artery arose from the left hepatic artery and divided into a left and a right branch. The left branch entered the liver through the porta hepatis, while the right branch passed behind the common hepatic duct into the Calot's triangle, provided 2 branches to the gallbladder, and continued to supply the right hepatic lobe. Ligation of the right branch of the right hepatic artery in Calot's triangle during cholecystectomy could cause avascular necrosis of the liver segments it supplies. PMID:24179698

    In order to determine the effect of oral magnesium sulfate on gallbladder contraction and release of cholecystokinin (CCK) in man, magnesium sulfate (25 g in 100 ml distilled water) was given by mouth to five fasting adult male volunteers. Plasma samples were collected for measurement of CCK by a specific radioimmunoassay. Gallbladder volumes were determined from sonograms obtained from a phased-array real-time ultrasound scanner. Basal concentrations of CCK (82.2 +/- 10.1 pg/ml) increased significantly at 20 minutes after oral magnesium sulfate (113.8 +/- 7.1 pg/ml), and reached a maximal value at 50 minutes (150.0 +/- 42.0 pg/ml). The mean basal volume of the gallbladder was 30.8 +/- 5.3 cm(3) and maximum reduction of gallbladder volume (to one third of original) was achieved at 50 minutes after ingestion of magnesium sulfate. Linear regression analysis showed a close correlation (r = -0.9337) between plasma concentrations of CCK and gallbladder size in response to magnesium sulfate. Oral magnesium sulfate also caused a significant increase in serum gastrin (from basal of 51.4 +/- 9.9 pg/ml to 69.8 +/- 15.5 pg/ml at 5 min); there was no significant correlation between gastrin release and gallbladder contraction. This study provides direct evidence that the mechanism of magnesium sulfate-stimulated gallbladder contraction occurs through the release of CCK, and shows a close correlation between CCK release and contraction of the gallbladder.

    Gallbladder cancer is a rare malignancy and presents a poor prognosis. MYC and p53 have been implicated in gallbladder carcinogenesis. However, little is known about the molecular mechanisms involved in their regulation in this neoplasia. Here, we evaluated the MYC and TP53 copy numbers in gallbladder tumors and their possible association with protein expression. We also investigated whether MYC may be controlled by mutations and DNA promoter methylation. In the present study, 15 samples of invasive gallbladder carcinomas and six control samples were analyzed. On the other hand, the expression of MYC and p53 was more frequent in gallbladder carcinomas than in control samples (p = 0.002, p = 0.046, respectively). Gain of copies of the MYC and TP53 genes was detected in 86.7 and 50 % of gallbladder carcinomas, respectively. MYC and TP53 amplifications were associated with immunoreactivity of their protein (p = 0.029, p = 0.001, respectively). MYC hypomethylation was only detected in tumoral samples and was associated with its protein expression (p = 0.029). MYC mutations were detected in 80 % of tumor samples. The G allele at rs117856857 was associated with the presence of gallbladder tumors (p = 0.019) and with MYC expression (p = 0.044). Moreover, two tumors presented a pathogenic mutation in MYC exon 2 (rs28933407). Our study highlights that the gain of MYC and TP53 copies seems to be a frequent finding in gallbladder cancer. In addition, gain of copies, hypomethylation and point mutations at MYC may contribute to overexpression of its protein in this type of cancer. PMID:25200035

    Among Mexican Americans the prevalence of gallbladder disease is markedly elevated. Previous data from both genetic admixture and family studies indicate that there is genetic component to the occurrence of gallbladder disease in Mexican Americans. However, prior to this study no formal genetic analysis of gallbladder disease had been carried out nor had any contributing gene been identified. The results of complex segregation analysis in a sample of 232 Mexican Americans with age- and gender-specific effects influencing the occurrence of gallbladder disease. The estimated frequency of the allele increasing susceptibility was 0.39. The lifetime probabilities that an individual will be affected by gallbladder disease were 1.0, 0.54, and 0.00 for females of genotypes {open_quotes}AA{close_quotes}, {open_quotes}Aa{close_quotes}, and {open_quotes}aa{close_quotes}, respectively, and 0.68, 0.30, and 0.00 for males, respectively. Human cholesterol 7a-hydroxylase is the rate-limiting enzyme in bile acid synthesis. The results of an association study in both a random sample and a matched case/control sample showed that there is a significant association between cholesterol 7a-hydroxylase gene variation and the occurrence of gallbladder disease in Mexican Americans males but not in females. For loci in the 5{prime}-end of the cholesterol 7a-hydroxylase gene, the frequency of the susceptibility alleles was twice as high in gallbladder disease patients compared to controls. The results of a linkage analysis provide evidence that the cholesterol 7a-hydroxylase gene and the inferred gallbladder disease gene are genetically linked.

    This study was undertaken to investigate the effect of erythromycin, a motilin agonist with prokinetic activity, on fasting gallbladder volume. To evaluate the mechanism of action of erythromycin on gallbladder motility, erythromycin (3.5 mg/kg.20 min, intravenously) was infused on three separate occasions: during cholinergic blockage with atropine (0.005 mg/kg.hr), during cholecystokinin receptor blockade with loxiglumide (10 mg/kg.hr) and during saline solution infusion (control). Atropine, loxiglumide and saline solution infusions were started 3 hr before administration of erythromycin and were continued for 3 hr thereafter. Gallbladder volumes (measured by ultrasonography), plasma cholecystokinin levels (radioimmunoassay) and plasma pancreatic polypeptide levels (radioimmunoassay) were determined at regular intervals for 6 hr in six healthy volunteers. During the 3-hr infusion before administration of erythromycin, both loxiglumide and atropine significantly increased gallbladder volumes--from 18 +/- 2 to 37 +/- 3 cm3 (p less than 0.05) and from 17 +/- 3 to 24 +/- 2 cm3 (p less than 0.05), respectively--whereas saline solution did not significantly affect gallbladder volume. During control saline solution infusion, erythromycin induced prolonged gallbladder contraction that was significant (p less than 0.05) between 60 and 180 min and reached a maximum of 45% +/- 8% at 150 min. Plasma cholecystokinin levels were not affected by erythromycin. Erythromycin induced a significant (p less than 0.05) increase in plasma pancreatic polypeptide levels, from 12 +/- 1 pmol/L to 34 +/- 3 pmol/L. Loxiglumide did not prevent the erythromycin-induced reduction in gallbladder volume. Atropine markedly reduced the effect of erythromycin, causing slight but significant (p less than 0.05) gallbladder volume reductions (18% +/- 4%) between 150 and 180 min.(ABSTRACT TRUNCATED AT 250 WORDS)

    A cystic artery aneurysm is a rare cause of hemobilia. Herein, we report two cases of acute cholecystitis with a ruptured cystic artery pseudoaneurysm. Two patients (a 69-year-old man and an 83-year-old man) were admitted to our hospital because of acute cholecystitis with gallstone impaction in the neck. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed for both patients. After a few days of PTGBD, gallbladder hemorrhage was observed. Abdominal angiography showed cystic artery aneurysm. A transcatheter arterial embolization was therefore performed, followed by an open cholecystectomy. PMID:27593367

    Although the diagnosis of bowel perforation is frequently straightforward, it may be difficult in the neonate. Clinical signs may be limited to abdominal distension. If the patient is on assisted ventilation, pneumoperitoneum may be due to air tracking down from the chest rather than perforation. Perforation in infants in whom the diagnosis could not readily be made from the clinical findings and plain radiographs was apparent when oral metrizamide was employed. This suggests that metrizamide can be a valuable adjunct in some cases of neonatal bowel perforation.

    Acquired reactive perforating collagenosis is a perforating dermatosis usually associated with different systemic diseases, mainly diabetes mellitus and/or chronic renal insufficiency. Different therapies have been tried but treatment is not standardized yet and remains a challenge. In the last few years, allopurinol has been reported as a good therapeutic option for acquired reactive perforating collagenosis. We describe the case of a 73-year-old man affected by acquired reactive perforating collagenosis associated with diabetes type 1 and chronic renal failure with secondary hyperparathyroidism. The patient was successfully treated with allopurinol 100mg once/day p.o.. PMID:23539010

    Ectopic liver and gallbladder are rare anomalies usually not accompanied by any symptoms and are found during surgical exploration or autopsy. We aimed to find a cause of this anomaly using somatic cell nuclear transfer (SCNT) technology, which can produce genetically identical organisms. A cloned beagle having ectopic organs was produced and died on the day of birth. Major and ectopic organs were fixed and underwent histologic analysis. SCNT was performed using cells derived from the dead puppy to produce reclones. Normality of internal organs in the original donor dog and recloned dogs was evaluated by computed tomography. While a liver without the gallbladder was located in the abdominal cavity of the cloned dog, a well-defined, reddish brown mass with a small sac was also positioned outside of the thoracic cavity. Histologically, they presented as normal liver and gallbladder. Five reclones were produced, and computed tomography results revealed that the original donor dog and reclones had normal liver and gallbladder structure and location. This is the first report of both ectopic liver and gallbladder in an organism and investigation on the etiology of these abnormalities. Normal organ structure and position in the original donor dog and reclones suggests that the ectopic liver and gallbladder is a possible nonheritable anomaly.

    This paper presents a new approach to gallbladder ultrasonic image processing and analysis towards automatic detection and interpretation of disease symptoms on processed US images. First, in this paper, there is presented a new heuristic method of filtering gallbladder contours from images. A major stage in this filtration is to segment and section off areas occupied by the said organ. This paper provides for an inventive algorithm for the holistic extraction of gallbladder image contours, based on rank filtration, as well as on the analysis of line profile sections on tested organs. The second part concerns detecting the most important 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. The methodology of computer analysis of US gallbladder images presented here is clearly utilitarian in nature and after standardising can be used as a technique for supporting the diagnostics of selected gallbladder disorders using the images of this organ.

    The patient was a 16-year-old boy who had turned to the right rapidly as he fielded a baseball that had come to him quickly. Two days after this event, which occurred in July 2004, he was admitted to hospital with repeated vomiting and increasing right hypochondralgia. Laboratory examination on admission showed elevation of the white blood count and of serum C-reactive protein and total bilirubin. Computed tomography on admission demonstrated an enlarged gallbladder and a thickened wall without gallstones, and magnetic resonance imaging performed 1 day later showed air within the gallbladder wall. His symptoms worsened, with a positive Murphy's sign, and emergency laparotomy was performed, with a diagnosis of emphysematous cholecystitis. Intraoperatively, the gallbladder was dark red, necrotic, distended, and enlarged. The cystic duct was attached only to the mesentery, and the gallbladder was floating freely, with the neck of the gallbladder having rotated 180 degrees counterclockwise, leading to a definitive diagnosis of gallbladder torsion with emphysematous cholecystitis. Cholecystectomy was performed, and analysis of bile showed Escherichia coli to be the causative organism. Histopathologic examination revealed necrotized cholecystitis. The patient is doing well 25 months after surgery, with an uneventful postoperative course.

    (/sup 3/H)dThd uptake by the gallbladder epithelium was estimated in 33 patients with cholesterol stones, in 13 patients with pigment stones, and in 12 gallbladders without stones. Proliferative parameters were estimated by autoradiography after in vitro incubation with (/sup 3/H)-dThd. Stones were identified by quantitative infrared spectroscopy. The degree of inflammation of the gallbladder wall was estimated by a histologic scoring method. In the gallbladders containing cholesterol stones the DNA synthesis index (1.39 +/- 0.28%) was higher (P less than .01) than in the gallbladders without stones (0.19 +/- 0.04%). No significant increase in proliferative parameters was found in the gallbladders with pigment stones (0.24 +/- 0.06%). No correlation was found between total stone number, weight or volume, and the DNA synthesis index. No evidence was observed that inflammation could influence the epithelial cell proliferation. Something in the bile of patients with cholesterol stones rather than the physical presence of stones may be the cause of the variations observed.

    Mexican Americans have a high prevalence of gallbladder disease. We examined the contribution of ethnic preferences in food intake to the risk of gallbladder disease in Mexican Americans and non-Hispanic whites. Participants in a population-based health survey were questioned about any history of gallbladder disease, and were interviewed to determine their dietary intake. After adjusting for age, body mass index, and ethnic group, we found that women with the highest intake of total fat and linoleic acid had reduced risks of gallbladder disease, although an opposite trend was observed in men. High levels of sucrose intake and low levels of cholesterol intake were associated with an increased risk for both sexes, but the odds ratios were not statistically significant. Although Mexican Americans and non-Hispanics differed in their intake of several nutrients, the elevated risk of gallbladder disease in Mexican American women was unchanged after ethnic differences in food intake were taken into account. Although the dietary preferences of Mexican Americans as reflected in 24-h diet recall interviews do not appear to explain their high prevalence of gallbladder disease, this finding should be interpreted with caution because of methodologic limitations in measuring habitual food intake.

    Takotsubo cardiomyopathy (TTC) is a form of acute left ventricular dysfunction usually reversible and with favorable prognosis. Ventricular septal perforation (VSP) is a very rare life-threatening complication. Percutaneous closure of VSP, despite being challenging, is a possible alternative to surgical repair. We present the first case of an 84-year-old patient with a TTC-related VSP treated by percutaneous approach. The case highlights the need of reconsidering the worldwide accepted consideration of TTC as benignant and allows some speculations on the optimal management of VSP in terms of timing, patient selection and possible alternative interventions.

    A downhole tool, adapted to retain a shaped charge surrounded by a superatmospherically pressurized light gas, is employed in a method for perforating a casing and penetrating reservoir rock around a wellbore. Penetration of a shaped charge jet can be enhanced by at least 40% by imploding a liner in the high pressure, light gas atmosphere. The gas pressure helps confine the jet on the axis of penetration in the latter stages of formation. The light gas, such as helium or hydrogen, is employed to keep the gas density low enough so as not to inhibit liner collapse.

    Suprapubic tube placement is a common urological procedure with a low incidence of complications, including hematuria, catheter blockage, recurrent urinary tract infections, and rarely, injury to adjacent organs. Fortunately, most serious complications are discovered shortly after initial suprapubic tube placement and are readily corrected. Very few cases of delayed complications or injuries have been reported. We report a case of Foley perforation into the ileum during suprapubic tube exchange discovered more than 8 months after initial placement, and preceding numerous monthly changes that occurred without incident. While a rare complication, physicians should be conscious of the potential for delayed injury in patients managed with long term suprapubic tube placement. PMID:19222896

    Endoscopically placed biliary stents have supplanted surgical decompression as the preferred treatment option for patients with obstructive jaundice from advanced pancreatic cancer. An unusual complication of indewelling biliary stents is duodenal perforation into the retroperitoneum. We describe the case of a patient with end-stage pancreatic cancer who presented with an acute abdomen from erosion of a previously placed bile duct stent through the wall of the second portion of the duodenum. Although our patient presented with advanced symptoms, clinical presentations can vary from mild abdominal discomfort and general malaise to overt septic shock. Definitive diagnosis is best made with computed tomography (CT) imaging, which can detect traces of retroperitoneal air and fluid. Treatment options vary from nonoperative management with antibiotics, bowel rest, and parenteral alimentation in the most stable patients to definitive surgery with complete diversion of gastric contents and biliary flow from the affected area in patients with clinical symptoms or radiologic evidence suggesting extensive contamination. Complications of management can include duodenal fistulization, residual retroperitoneal or intrabdominal abscess, and ongoing sepsis. This report highlights the salient issues in the presentation, diagnosis, and modern management of patients with this rare complication of indwelling biliary stents.

    INTRODUCTION Atypical presentations of appendix have been reported including backache, left lower quadrant pain and groin pain from a strangulated femoral hernia containing the appendix. We report a case presenting an epigastric pain that was diagnosed after computed tomography as a perforated appendicitis on intestinal malrotation. PRESENTATION OF CASE A 27-year-old man was admitted with a three-day history of epigastric pain. Physical examination revealed tenderness and defense on palpation of epigastric region. There was a left subcostal incision with the history of diaphragmatic hernia repair when the patient was 3 days old. He had an intestinal malrotation with the cecum fixed at the epigastric region and the inflamed appendix extending beside the left lobe of liver. DISCUSSION While appendicitis is the most common abdominal disease requiring surgical intervention seen in the emergency room setting, intestinal malrotation is relatively uncommon. When patients with asymptomatic undiagnosed gastrointestinal malrotation clinically present with abdominal pain, accurate diagnosis and definitive therapy may be delayed, possibly increasing the risk of morbidity and mortality. CONCLUSION Atypical presentations of acute appendicitis should be kept in mind in patients with abdominal pain in emergency room especially in patients with previous childhood operation for diaphragmatic hernia.

    Evaluation of the severity of acute cholecystitis is critical for the management of this condition. Superb microvascular imaging (SMI) enables the assessment of slow blood flow of small vessels without any contrast medium. An 84-year-old man visited our hospital with right upper abdominal pain. Computed tomography and abdominal ultrasonography showed a slight thickening of the gallbladder. White blood cell count and C-reactive protein levels were elevated. He was diagnosed with acute cholecystitis and treated conservatively with antibiotics. Two days later, his condition worsened and percutaneous transhepatic gallbladder drainage (PTGBD) was performed. The patient recovered and was discharged, and his drainage was withdrawn 7 days later. On admission, color-coded SMI (cSMI) showed pulsatory signals on the slightly thickened gallbladder wall. On the day of PTGBD, the intensity of the signal on cSMI had increased. Once the patient was cured, no further signal was observed on the gallbladder wall with either cSMI or mSMI. In conclusion, the strong pulsatory signal correlated with the severity of acute cholecystitis observed with cSMI and mSMI. Illustrating the signal intensity is useful for the evaluation of the severity of acute cholecystitis. PMID:27721732

The ability of the antispasmodic drugs atropine, N-butylscopolamine, papaverine, trimebutine, dicyclomine, and rociverine to delay gallbladder emptying was determined by administering them either intraperitoneally or orally 7.5 or 15 min prior to egg yolk.

    Introduction Cholecystectomy for benign gallbladder diseases can lead to previously undiagnosed gallbladder cancer during histopathological evaluation. Despite some controversy over its usefulness, histopathological evaluation of all gallbladder specimens is common in most hospitals. We evaluated the results of routine pathology of the gallbladder after cholecystectomy for benign gallbladder diseases with regard to unexpected primary gallbladder cancer (UPGC). Methods Patients undergoing cholecystectomy because of benign gallbladder diseases between 2009 and 2013 were enrolled in this study. All gallbladder specimens were sent to the pathology department, and histopathological reports were examined in detail. The impact of demographic features on pathological diagnoses and prevalence of UPGC assessed. Data on additional interventions and postoperative survival for patients with UPGC were collected. Results We enrolled 1,747 patients (mean age, 48.7±13.6 years). Chronic cholecystitis was the most common diagnosis (96.3%) and was associated significantly with being female (p=0.001). Four patients had UPGC (0.23%); one was stage T3 at the time of surgery, and the remaining three cases were stage T2. Conclusions Routine histopathological examination of the gallbladder is valuable for identification of cancer that requires further postoperative management.

    Bevacizumab is the first U.S. Food and Drug Association-approved vascular endothelial growth factor-targeted agent that greatly increases progression-free and overall survival in combination with standard chemotherapy regimens in patients with metastatic colorectal cancer. Although bevacizumab is generally well tolerated, some serious adverse events have occurred in some patients in clinical trials, including arterial thromboembolism and gastrointestinal (GI) perforation. GI perforation was first observed in the pivotal phase 3 trial, in which six events occurred in bevacizumab group (1.5%), compared with no events in the control group. Since then, similar rates of GI perforation have been observed in other large trials. Typical presentation was abdominal pain associated with constipation and vomiting. Such events occurred throughout treatment and were not correlated with duration of exposure. No difference in rate of GI perforations was found in patients who did and did not have a baseline history of peptic ulcer disease, diverticulosis, and history of chronic use of nonsteroidal anti-inflammatory drugs. However, the incidence of GI perforation seemed to be higher in patients with primary tumor intact, recent history of sigmoidoscopy or colonoscopy, or previous adjuvant radiotherapy, but it is necessary to confirm these preliminary findings by multivariate analyses. The mechanism responsible for causing GI perforation is not known and may be multifactorial. Bevacizumab should be permanently discontinued in patients who develop GI perforation. This article reviews the incidence, presentation, pathogenesis, risk factors, and management of GI perforation in patients with colorectal cancer who are treated with bevacizumab.

    After increasing steeply at the beginning of the twentieth century, ulcer perforation incidence during the last decades has declined in the young and in men, and it has risen among the elderly and in women. These changes can be attributed to a cohort phenomenon: Ulcer perforation risk is particularly common in the cohorts born after the turn of the twentieth century and is less common in previous and succeeding birth cohorts. A decline in total incidence is expected with the death of the high risk cohorts. Most ulcer perforations among subjects < 75 years of age can be attributed to smoking. Subjects with a history of ulcer perforation therefore have poorer long-term survival than the general population, most pronounced for younger generations. About one of four ulcer perforations can be attributed to the use of nonsteroidal antiinflammatory drugs, a risk factor of particular importance in the elderly. Ulcer perforation was frequently treated by gastric resection in former days, whereas suture, being the first method introduced in 1887, is the method of choice today. The introduction of antibiotics improved the prognosis of ulcer perforation surgery greatly. Postoperative lethality decreased until 1950 but has remained stable since then. Lethality is higher in the elderly and is higher after gastric than after duodenal perforation. The delay before surgical treatment is a strong determinant for lethality, complication rates, and hospital costs. Treatment delay seems to have increased during the last

    Completion of cased and cemented wells by shaped-charge perforation results in damage to the formation, which can significantly reduce well productivity. Typically, underbalanced conditions are imposed during perforation in an effort to remove damaged rock and shaped-charge debris from the perforation tunnel. Immediately after the shaped-charge jet penetrates the formation, there is a transient surge of fluid from the formation through the perforation and into the well bore. Experimental evidence suggests that it is this transient pressure surge that leads to the removal of damaged rock and charge debris leaving an open perforation tunnel. We have developed a two-stage computational model to simulate the perforation process and subsequent pressure surge and debris removal. The first stage of the model couples a hydrocode with a model of stress-induced permeability evolution to calculate damage to the formation and the resulting permeability field. The second stage simulates the non-Darcy, transient fluid flow from the formation and removes damaged rock and charge debris from the perforation tunnel. We compare the model to a series of API RP43 section 4 flow tests and explore the influence of fluid viscosity and rock strength on the final perforation geometry and permeability.

Objectives: To identify expression of CCK-A and CCK-B receptors in the tissue and blood of patients suffering from carcinoma (CA) gallbladder and gallstone disease and to compare expression of CCK A and B receptors in the gall bladder tissue and blood of healthy individuals and patients of CA gallbladder, and gallstone diseases. Materials and Methods: Forty nine subjects of both genders were recruited, comprising of 22 patients of CA gall bladder, 19 cases of cholelithiasis and, 8 normal gallbladders obtained from patients operated for trauma of the biliary system or Whipple’s procedure. RNA extraction and cDNA formation for CCK-A and CCK-B receptors were carried out. Real Time PCR was performed on cDNA and threshold cycle (Ct) value of each sample was obtained and ΔCt was calculated. Chi-square test for comparing two groups and ANOVA test for comparing multiple groups were applied and if p<0.05 then Dunnett-C test was performed. Observation and Results: Both CCK-A and CCK-B receptors were expressed irrespective of its origin in all tissues and blood samples studied; be it normal, Cholelithiasis or CA gallbladder and there was no difference among them (p>0.05). Conclusion: This preliminary study showed higher expression of CCK-A receptors in patients of cholelithiasis and decreased expression of CCK-A receptors in patients of CA gallbladder as compared to normal gallbladder although it did not rise to statistical significance.

    Background Perforated peptic ulcer is a serious complication of peptic ulcers with potential risk of grave complications. There is paucity of published reports on perforated peptic ulcer disease in our local environment. This study was conducted to evaluate the clinical presentation, management and outcome of patients with peptic ulcer perforation in our setting and to identify predictors of outcome of these patients. Methods This was a combined retrospective and prospective study of patients who were operated for perforated peptic ulcers at Bugando Medical Centre between April 2006 and March 2011. Data were collected using a pre-tested and coded questionnaire and analyzed using SPSS computer software version 15.0. Ethical approval to conduct the study was obtained from relevant authority before the commencement of the study. Results A total of 84 patients were studied. Males outnumbered females by a ratio of 1.3: 1. Their median age was 28 years and the modal age group was 21-30 years. The median duration of illness was 5.8 days. The majority of patients (69.0%) had no previous history of treatment for peptic ulcer disease. The use of non-steroidal anti-inflammatory drugs, alcohol and smoking was reported in 10.7%, 85.7% and 64.3% respectively. Eight (9.5%) patients were HIV positive with a median CD4 count of 220 cells/μl. Most perforations were located on the duodenum {90.4%) with the duodenal to gastric ulcers ratio of 12.7: 1. Graham's omental patch (Graham's omentopexy) of the perforations was performed in 83.3% of cases. Complication and mortality rates were 29.8% and 10.7% respectively. The factors significantly related to complications were premorbid illness, HIV status, CD 4 count < 200 cells/μl, treatment delay and acute perforation (P < 0.001). Mortality rate was high in patients who had age ≥ 40 years, delayed presentation (>24 hrs), shock at admission (systolic BP < 90 mmHg), HIV positivity, low CD4 count (<200 cells/μl), gastric ulcers

    To perforate tissue lying deep part in body, a large size transducer was assembled by combining four spherical-shaped transducers, and the optimal conditions for tissue perforation have studied using ventricle muscle of chicken as a target. The ex vivo experiments showed that ventricle muscle was successfully perforated both when it was exposed to High Intensity Focused Ultrasound (HIFU) directly and when it was exposed to HIFU through atrial muscle layer. Moreover, it was shown that calculated acoustic power distributions are well similar to the perforation patterns, and that the acoustic energy distributes very complexly near the focus. Lastly, perforation on the living rabbit bladder wall was demonstrated as a preliminary in vivo experiment.

    The present work explored the feasibility of controlling the acoustic impedance of a resonant type acoustic liner. This was accomplished by translating one perforate over another of the same porosity creating a totally new perforate that had an intermediate porosity. This type of adjustable perforate created a variable orifice perforate whose orifices were non-circular. The key objective of the present study was to quantify, the degree of attenuation control that can be achieved by applying such a concept to the buried septum in a two-degree-of-freedom (2DOF) acoustic liner. An additional objective was to examine the adequacy of the existing impedance models to explain the behavior of the unique orifice shapes that result from the proposed silding perforate concept. Different orifice shapes with equivalent area were also examined to determine if highly non-circular orifices had a significant impact on the impedance.

  15. Clinicopathological significance of SOX4 expression in primary gallbladder carcinoma

    2012-01-01

    Aim SOX4, as a member of the SRY-related HMG-box (SOX) transcription factor family, has been demonstrated to be involved in tumorigenesis of many human malignancies; however, its role in primary gallbladder carcinoma (PGC) is still largely unknown. The aim of this study was to investigate SOX4 expression in PGC and its prognostic significance. Methods From 1997 to 2006, 136 patients underwent resection for PGC. The median follow-up was 12.8 months. Immunostainings for SOX4 were performed on these archival tissues. The correlation of SOX4 expression with clinicopathological features including survival was analyzed. Results SOX4 was expressed in 75.0% (102/136) of PGC but not in the normal epithelium of the gallbladder. In addition, the over-expression of SOX4 was significantly associated with low histologic grade (P = 0.02), low pathologic T stage (P = 0.02), and early clinical stage (P = 0.03). The levels of SOX4 immunostainings in PGC tissues with positive nodal metastasis were also significantly lower than those without (P = 0.01). Moreover, Kaplan-Meier curves showed that SOX4 over-expression was significantly related to better overall (P = 0.008) and disease-free survival (P = 0.01). Furthermore, multivariate analyses showed that SOX4 expression was an independent risk factor for both overall (P = 0.03, hazard ratio, 3.682) and disease-free survival (P = 0.04, hazard ratio, 2.215). Conclusion Our data indicate for the first time that the over-expression of SOX4 in PGC was significantly correlated with favorable clinicopathologic features and was an independent prognostic factor for better overall and disease-free survival in patients. Therefore, SOX4 might be an auxiliary parameter for predicting malignant behavior for PGC.

    Introduction Cancer of the gallbladder is a serious diagnostic and therapeutic problem. According to the literature, 30% of cases are not confirmed before surgery. Other cases are detected incidentally by histopathology. Clinical trials and meta-analyses show that incidental gallbladder cancer (iGBC) occurs in 0.19%–2.8% of patients after cholecystectomy. The aim of this study was to analyze the incidence and severity of iGBC in cholecystectomy procedures performed in the surgical department at the 4th Military Teaching Hospital in Wroclaw during the years 1990–2014. Patients and methods In the years 1990–2014, a total of 7,314 cholecystectomies were performed in the surgical department because of cholecystolithiasis: 6,145 were performed using the laparoscopic approach (84.02%), 867 were performed as open surgery (11.8%), and 302 cases required conversion (5.1%). In this group, 5,214 of the patients were females (71.3%) and 2,100 were males (28.7%), with an average age of 54.7 years. Results We found 64 iGBC cases which were confirmed by histopathology. This represented 0.87% of all cases. In this group, 50 patients were females (78.1%) and 14 were males (21.8%), with an average age of 67.1 years. Of this group, 40 patients underwent a classic cholecystectomy, while 24 underwent laparoscopic procedures, out of which 13 cases ultimately required traditional surgery. The histopathology showed 15 carcinomas that were classified as G1 (23.4%), 28 were G2 (43.75%), and 21 were G3 (32.8%). Conclusion iGBC detected after a cholecystectomy due to cholecystolithiasis is a rare disease. We found iGBC in 0.87% of cases, which is on a comparable scale to the world literature. In the case of cancer, we frequently found it necessary to convert to an open surgical procedure. This cancer is more common in females and in people over 60 years of age. PMID:27540304

    Gluteal artery perforator flaps have gained popularity due to reliability, preservation of the muscle, versatility in flap design without restricting other flap options, and low donor-site morbidity in ambulatory patients and possibility of enabling future reconstruction in paraplegic patients. But the inconstant anatomy of the vascular plexus around the gluteal muscle makes it hard to predict how many perforators are present, what their volume of blood flow and size are, where they exit the overlying fascia, and what their course through the muscle will be. Without any prior investigations, the reconstructive surgeon could be surprised intraoperatively by previous surgical damage, scar formation, or anatomic variants.For these reasons, to confirm the presence and the location of gluteal perforators preoperatively we have used color Doppler ultrasonography. With the help of the color Doppler ultrasonography 26 patients, 21 men and 5 women, were operated between the years 2002 and 2007. The mean age of patients was 47.7 (age range: 7-77 years). All perforator vessels were marked preoperatively around the defect locations. The perforator based flap that will allow primary closure of the donor site and the defect without tension was planned choosing the perforator that showed the largest flow in color Doppler ultrasonography proximally. Perforators were found in the sites identified with color Doppler ultrasonography in all other flaps. In our study, 94.4% flap viability was ensured in 36 perforator-based gluteal area flaps. Mean flap elevation time was 31.9 minutes. We found that locating the perforators preoperatively helps to shorten the operation time without compromising a reliable viability of the perforator flaps, thus enabling the surgeon easier treatment of pressure sores.

    Purpose To evaluate the diagnostic performance of ultrasonography (US) in the identification and exclusion of biliary atresia with a modified triangular cord thickness metric together with a gallbladder classification scheme, as well as hepatic artery (HA) diameter and liver and spleen size, in a large sample of jaundiced infants. Materials and Methods The ethics committee approved this study, and written informed parental consent was obtained. In 273 infants with conjugated hyperbilirubinemia (total bilirubin level ≥ 31.2 μmol/L, with direct bilirubin level > indirect bilirubin level), detailed abdominal US was performed to exclude biliary atresia. Biliary atresia was found in 129 infants and ruled out in 144. A modified triangular cord thickness was measured at the anterior branch of the right portal vein, and a gallbladder classification scheme was identified that incorporated the appearance of the gallbladder and a gallbladder length-to-width ratio of up to 5.2 when the lumen was visualized, as well as HA diameter and liver and spleen size. Reference standard diagnosis was based on results of one or more of the following: surgery, liver biopsy, cholangiography, and clinical follow-up. Area under the receiver operating characteristic curve (AUC) analysis, binary logistic regression analysis, Fisher exact test, and unpaired t test were performed. Results Triangular cord thickness, HA diameter, ratio of gallbladder length to gallbladder width, liver size, and spleen size exhibited statistically significant differences (all P < .05) between the group with biliary atresia and the group without. AUCs of triangular cord thickness, ratio of gallbladder length to width, and HA diameter were 0.952, 0.844, and 0.838, respectively. Logistic regression analysis demonstrated that these three US parameters were significantly associated (all P < .05) with biliary atresia. The combination of triangular cord thickness and gallbladder classification could yield comparable AUCs

    Background Although tympanic membrane perforations are common, there have been few systematic studies of the structural features determining the magnitude of the resulting conductive hearing loss. Our recent experimental and modeling studies predicted that the conductive hearing loss will increase with increasing perforation size, be independent of perforation location (contrary to popular otologic belief), and increase with decreasing size of the middle-ear and mastoid air space (an idea new to otology). Objective To test our predictions regarding determinants of conductive hearing loss in tympanic membrane perforations against clinical data gathered from patients. Study Design Prospective clinical study. Setting Tertiary referral center. Inclusion Criteria Patients with tympanic membrane perforations without other middle-ear disease. Main Outcome Measures Size and location of perforation; air-bone gap at 250, 500, 1,000, 2,000, and 4,000 Hz; and tympanometric estimate of volume of the middle-ear air spaces. Results Isolated tympanic membrane perforations in 62 ears from 56 patients met inclusion criteria. Air-bone gaps were largest at the lower frequencies and decreased as frequency increased. Air-bone gaps increased with perforation size at each frequency. Ears with small middle-ear volumes, ≤4.3 ml (n = 23), had significantly larger air-bone gaps than ears with large middle-ear volumes, >4.3 ml (n = 39), except at 2,000 Hz. The mean air-bone gaps in ears with small volumes were 10 to 20 dB larger than in ears with large volumes. Perforations in anterior versus posterior quadrants showed no significant differences in air-bone gaps at any frequency, although anterior perforations had, on average, air-bone gaps that were smaller by 1 to 8 dB at lower frequencies. Conclusion The conductive hearing loss resulting from a tympanic membrane perforation is frequency-dependent, with the largest losses occurring at the lowest sound frequencies; increases as size of the

    Meckel's diverticulum is the commonest congenital abnormality of the gastrointestinal tract. Hemorrhage, obstruction and inflammation are the three main categories of complications resulting from Meckel's diverticulum. Spontaneously perforation of Meckel's diverticulum is very rare and mimics acute appendicitis. We report a case of 26 year-old male, who presented since 5 days worsening abdominal pain predominantly in the right iliac fossa associated with high grade fever. On physical examination his abdomen was distended with guarding and rigidity. A provisional diagnosis of appendiculaire peritonitis was made. Our patient had an emergency laparotomy, where a perforated Meckel's diverticulum and advanced peritonitis were discovered. A diverticulectomy with ileostomy were performed. Heterotopic mucosa of diverticulitis was confirmed on histopathology. The patient made an uneventful recovery postoperatively and ileostomy reconstruction was done two months later. This case report is an interesting and unusual case of Meckel's diverticulum complications and highlights the importance of considering Meckel's diverticulum as a differential diagnosis in every patient presenting with acute abdomen.

  1. Role of bacteria in carcinogenesis, with special reference to carcinoma of the gallbladder

    2010-01-01

    Carcinoma of the gallbladder (CaGB) is the fifth commonest gastrointestinal tract cancer and is endemic in several countries. The interplay of genetic susceptibility, infections, and life style factors has been proposed to be responsible for carcinogenesis of gallbladder. Persistence of infection leading to chronic inflammation, and production of certain toxins and metabolites with carcinogenic potentials, by certain bacteria has been speculated to be involved in the transformation of the gallbladder epithelium. Therefore, any bacteria that have evolved to acquire both of the above carcinogenic mechanisms can cause cancer. Salmonella typhi has been found to be prominently associated with CaGB. Chronic typhoid carriage (persistence) and production of mediators of chronic inflammation and a genotoxic toxin (cytotoxic distending toxin, CdtB) are also known for this bacterium. Furthermore, the natural concentrating function of the gallbladder might amplify the carcinogenic effect of the mediators of carcinogenesis. In addition to S. typhi, certain species of Helicobacter (H. bilis and H. hepaticus) and Escherichia coli have also been implicated in carcinogenesis. As the isolation rate is very poor with the presently available culture techniques, the existence of bacteria in a viable but non-cultivable state is quite likely; therefore, sensitive and specific molecular techniques might reveal the etiological role of bacterial infection in gallbladder carcinogenesis. If bacteria are found to be causing cancers, then eradication of such infections might help in reducing the incidence of some cancers. PMID:21086555

    Two-photon excited fluorescence (TPEF) microscopy, based on signal from cells, can provide detailed information on tissue architecture and cellular morphology in unstained histological sections to generate subcellular-resolution images from tissue directly. In this paper, we used TPEF microscopy to image microstructure of human normal gallbladder and three types of differentiated carcinomas in order to investigate the morphological changes of tissue structure, cell, cytoplasm, and nucleus without hematoxylin and eosin (H&E) staining. It displayed that TPEF microscopy can well image the stratified normal gallbladder tissue, including the mucosa, the muscularis, and the serosa. The typical cancer cell, characterized by cellular and nuclear pleomorphism, enlarged nuclei, and augmented nucleolus, can be identified in histological sections without H-E staining as well. The quantitative results showed that the areas of the nucleus and the nucleolus in three types of cancerous cells were all significantly greater than those in normal gallbladder columnar epithelial cells derived from TPEF microscopic images. The studies demonstrated that TPEF microscopy has the ability to characterize tissue structures and cell morphology of gallbladder cancers differentiated from a normal gallbladder in a manner similar to traditional histological analysis. As a novel tool, it has the potential for future retrospective studies of tumor staging and migration by utilizing histological section specimens without H-E staining.

    Schwannomas occurring in the gallbladder are extremely rare. Preoperative diagnosis of gallbladder schwannomas appears to be very difficult because they are normally asymptomatic and are often found incidentally. Until now, only five cases have been reported in the literature. To our knowledge, the contrast-enhanced ultrasound (CEUS) features of gallbladder schwannomas have not been reported before in other studies. We treated a 55-year-old male patient with gallbladder schwannoma in China. He had no symptoms, and the lesion was incidentally found by conventional ultrasound (US) when performing a health examination. The patient had normal liver function; moreover, serum carcinoembryonic antigen and alpha-fetoprotein were within the normal ranges. The lesion showed no blood flow signals on color Doppler US, and the wall beneath the lesion was intact on CEUS. The lesion was believed to be a benign entity; in addition, gallbladder adenomyomatosis was suspected. A laparoscopic cholecystectomy was performed to remove the mass. Pathological examination revealed that the tumor was mainly composed of spindle-shaped cells; neither atypical cells nor signs of malignancy were found. Immunohistochemical staining showed a strong positive S-100 protein reaction. Vimentin and CD56 staining were also positive, whereas CD34 and CD117 were negative. Finally, the lesion was diagnosed as schwannoma. Herein, we report the case; the associated literature is also reviewed.

    An 80-year-old male was referred to our department for a gallbladder mass. He denied any history of alcohol consumption or cholecystitis and smoking. Hepatitis B surface antigen test and antihepatitis C antibody test were found to be negative. Serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen were elevated (CA19-9 was 59.92 U/mL and carcinoembryonic antigen was 12.64 ng/mL), whereas alpha-fetoprotein was below the normal limit (2.46 ng/mL). Computed tomography scan revealed a solid mass with measurements of 4.6×5.6×7.1 cm, which nearly filled the whole gallbladder space. Radical cholecystectomy, including segments IV B and V of the liver and lymphadenectomy, was performed. The neoplasm in gallbladder was completely resected, and the patient obtained a negative margin. Histological and immunohistochemical profile suggested a clear cell adenocarcinoma of the gallbladder with hepatoid differentiation. After reviewing the literature, we reported that this case is the first identified case of cell adenocarcinoma of the gallbladder with extensive hepatoid differentiation. However, clinical features of clear cell adenocarcinoma with hepatoid differentiation remain unclear due to the extremely rare incidence. There was no indication of adjuvant chemotherapy and no literature has been reported on the application of chemotherapy. This case showed a promising clinical outcome after curative resection, which indicated that surgical treatment could be potentially considered for suitable patients. PMID:27703378

    The Italian surgeon needs to know the real situation about gallbladder carcinoma in Italy, his professional field of action: real incidence, sex and age characteristics and regional distribution with useful correlations to define the risk population. We can use nowadays the ISTAT data (since 1969 also in magnetic tape) about such neoplasia, based on death denunces. These differentiate gallbladder carcinoma from others hepatobiliary neoplasms and are referred to the whole national territory and allow and analyze for the various regions a period of 18 years (from 1970 to 1987). We have therefore the facility of a statistical index which give us the possibility to compare directly the specific mortality taxes between very different regions of residence from the point of view of population density, sex and age distribution on each year of the period considered. Also in Italy incidence of gallbladder carcinoma shows an absolute and relative increasing with age in both sexes, reaching the peak in the seventy's, with a M/F rate between 1/3 to 1/2, and with global incidence that is increasing in the last years. Risk factors could be in the age older than 50 years, in the females, in the long standing gallbladder lithiasis with wide cholesterinic stones on the basis of a chronic inflammation and consequent dysplasia, in the diet more far from the mediterranean's, and finally in papillomas and papillomatosis of gallbladder.

Hepatic and pancreatic enzymes were elevated. Her serum alanine aminotransferase (ALT) level was high. An initial abdominal ultrasound was per-formed at hospital and revealed features of acute viral hepatitis. Spiral computed imaging revealed imaging features of an acute stage of pancreatitis and gallbladder wall thickness. HAV infection was diagnosed by the detection of immunoglobulin M (IgM) against HAV in the serum. She was closely monitored and treated conservatively. On 10th day of hospital admission she was discharge after an uneventful recovery. In the current literature HAV infections have rarely been reported as a cause of acute pancreatitis.

    In recent years, a number of alternatives to surgery for gallstones have been developed. Among them, extracorporeal shock-wave lithotripsy (ESWL) was promising, being non-invasive and risk-free. Nevertheless, its results vary according to the size, number and composition of the stones and according to the bile acids treatment used for fragment dissolution. To better evaluate the importance of these factors, we have widened the selection criteria currently used (1 to 3 non-calcified stones with a diameter below 30 mm) by including patients with large stones (up to 40 mm in diameter), multiple stones (up to 10 stones) and calcified stones. We also compared, for efficacy of fragment dissolution after ESWL, treatment by ursodeoxycholic acid alone as opposed to a mixture with chenodeoxycholic acid. Our results were (1) significant lessening of the fragmentation rate and of the number of gallbladders free of stones 1 year after ESWL when selection criteria are widened; (2) a mixture of ursodeoxycholic and chenodeoxycholic acids may favour fragment dissolution after ESWL compared to treatment by ursodeoxycholic acid alone.

    Penetrating abdominal trauma is a major killer worldwide. Various modes and mechanisms of injury have been described in world literature. We describe an unusual case of penetrating intra-abdominal injury caused by a 2-ft-long needle fish at sea. The mode and mechanism of injury is rare and the consequences life threatening. There is paucity in the literature of such trauma and its presentation. This case report describes injury sustained by a fisherman at sea by a needle fish, causing biliary peritonitis from an isolated penetrating injury to the gallbladder. Typically, these fishes are known to jump up to 6 ft above the surface of the water and are voracious carnivores, feeding on smaller fishes in deep sea. The fisherman, having sustained the injury, had blood tinged bile oozing from the wound and attended casualty in severe abdominal pain and nausea. Diagnosis was prompt, and even though the presentation to the casualty was delayed, immediate resuscitative measures and surgery ensured successful management of the patient. PMID:27303126

    Patient: Female, 81 Final Diagnosis: Gallbladder papillomatosis Symptoms: Epigastric pain Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Biliary papillomatosis (BP) with sole involvement of the gall bladder or gall bladder papillomatosis (GBP) is very rare. Biliary-enteric fistula, particularly the cholecystocolonic fistula (CCF) type, is also very rare. The combination of both types of lesions in a single patient has never previously been reported in the English literature. Case Report: We report herein the case of an 81-year-old woman who was diagnosed with both disease entities, which occurred in a cause-and-effect relationship. She underwent resection of the gall bladder with closure of the fistula, and was discharged improved afterwards. Conclusions: GBP is a premalignant condition that warrants extensive resection. An absent Murphy’s sign or jaundice on physical examination should not rule out this disease or accompanying biliary tract infection because a biliary-enteric fistula may be present. Thorough review of the radiologic images should be performed, since subtle details could be easily missed or dismissed, thus affecting the postoperative course. A CCF should alert the physician that another disease entity is present. PMID:25351203

    MicroRNAs (also referred to as miRNAs or miRs) play a crucial role in post-transcriptional gene regulation and serve as negative gene regulators by controlling a variety of target genes and regulating diverse biological processes, such as cell proliferation, invasion, migration and apoptosis. Aberrant expression of miRNAs is associated with the development and progression of cancer. Recent studies have reported that miRNAs may repress or promote the expression of cancer-related genes via several different signaling pathways in gallbladder cancer (GBC) patients and may function as tumor suppressors or oncogenes, thus providing a promising tool for the diagnosis and therapeutics of GBCs. In this review, we summarize the role of dysregulawted miRNA expression in the signaling pathways implicated in GBC and discuss the significant role of circulating miRNAs in GBC. Therefore, miRNAs may serve as novel therapeutic targets as well as diagnostic or prognostic markers in GBC. PMID:27330755

The authors divided the 40 cases into two groups: 20 without positive nodes and 20 with positive nodes. In the group without positive nodes, one patient who underwent R1 resection died of a recurrence at 1 year 7 months. Seventeen of the 19 patients treated with R0 resection survived more than 5 years. The 5-year survival rate was 85% (17/20). In the group with positive nodes, 9 of the 13 patients treated with R0 resection survived more than 5 years, whereas the seven patients treated with R1 or R2 resection died within 5 years. The 5-year survival rate was 45% (9/20). Patients treated by R0 resection showed a 5-year survival rate of 69% (9/13). Thus we documented the favorable long-term results of radical surgery. R0 resection is a prerequisite for long-term survival. The results justify radical surgery with lymph node dissection. PMID:1359844

    We study multiple tearing of a thin, elastic, brittle sheet indented with a rigid cone. The n cracks initially prepared symmetrically propagate radially for n ≥4 . However, if n <4 the radial symmetry is broken and fractures spontaneously intertwine along logarithmic spiral paths, respecting order n rotational symmetry. In the limit of very thin sheets, we find that fracture mechanics is reduced to a geometrical model that correctly predicts the maximum number of spirals to be strictly 4, together with their growth rate and the perforation force. Similar spirals are also observed in a different tearing experiment (this time up to n =4 , in agreement with the model), in which bending energy of the sheet is dominant.

    Thermal imaging detects infrared radiation from an object, producing a thermogram that can be interpreted as a surrogate marker for cutaneous blood flow. To date, high-resolution cameras typically cost tens of thousands of dollars. The FLIR ONE is a smartphone-compatible miniature thermal imaging camera that currently retails at under $200. In a proof-of-concept study, patients and healthy volunteers were assessed with thermal imaging for (1) detecting and mapping perforators, (2) defining perforasomes, and (3) monitoring free flaps. Preoperative, intraoperative, and postoperative thermograms can assist in the planning, execution, and monitoring of free flaps, and the FLIR ONE provides a low-cost adjunct that could be applied to other areas of burns and plastic surgery.

    POD Associates have revisited the issue of generic scaling laws able to adequately predict (within better than 20 percent) cratering in semi-infinite targets and perforations through finite thickness targets. The approach used was to apply physical logic for hydrodynamics in a consistent manner able to account for chunky-body impacts such that the only variables needed are those directly related to known material properties for both the impactor and target. The analyses were compared and verified versus CTH hydrodynamic code calculations and existing data. Comparisons with previous scaling laws were also performed to identify which (if any) were good for generic purposes. This paper is a short synopsis of the full report available through the NASA Langley Research Center, LDEF Science Office.

    Cholescintigraphy is a sensitive procedure for diagnosing or excluding acute cholecystitis. However, when rapid diagnosis is critical, the requirement for delayed images (4 hr or more after injection) to minimize the false-positive rate diminishes its utility. We prospectively evaluated 40 cholescintigraphic examinations that did not visualize the gallbladder 1 hr after injection of 99mTc diisopropyliminodiacetic acid. These examinations were then augmented by administration of IV morphine, followed by an additional 30 min of imaging. After the morphine, 18 of these examinations demonstrated visualization of the gallbladder; none subsequently required surgical exploration. Of the remaining 22, who demonstrated persistent nonvisualization of the gallbladder post-morphine, 11 were explored surgically and found to be abnormal. The 11 others were treated medically. Low-dose morphine administered when the gallbladder fails to visualize after 1 hr is a useful adjunct to conventional cholescintigraphy because it reduces the time required to obtain a diagnostic result and decreases the number of false-positive results.

    For clinical use of the excimer laser more detailed knowledge of corneal wound healing is necessary. With an ArF excimer laser (193 nm, 750 mJ/cm2, 20 Hz) and a special slit mask system perforating and non-perforating keratectomies were performed in a series of 55 rabbits with a follow-up from one hour to six months post-op. After enucleation the corneas were immediately processed for light microscopy, scanning and transmission electron microscopy and vital staining of the endothelium (trypan blue/alizarin red S). In perforating cuts the endothelial reaction consists of polymegathism, migration, formation of multi-nucleated giant cells, metaplasia-like proliferation and ultimately stable reformation of the cell pattern (1h to 42d). Epithelium fills the anterior wound gap within three days with subsequent regression of the plug. Fibroblastic activity in the adjacent stroma leads to cellular immigration, production of new collageneous lamellae and complete reorganization of the wound cleft (1d to 6m). Nonperforating excisions showed similar healing tendency of stroma and epithelium, but no severe endothelial damage could be detected. Compared with former studies using knife incisions our results do not reveal significant difference regarding epithelial and stromal wound healing events. The encouraging healing tendency of the endothelium--similar to regeneration after ultrasound and Nd:YAG-laser damage--also confirms the applicability of excimer lasers in corneal surgery.

    There are two general categories of lateral osteotomy techniques-the external perforating method and the internal continuous method. Regardless of which technique is used, procedural effectiveness is hampered by limited visualization in the surgical field. Considering this point, we devised a new technique that involves using a wide subperiosteal dissection and internal perforation under direct visualization. Using an intranasal approach, whereby the visibility of the intended fracture line was maintained, enabled a greater degree of control, and in turn, results that were more precise, and thus predictable and reproducible. Traditionally, it has been taken as dogma that the periosteum must be preserved, considering the potential for dead space and bony instability; however, under sufficient visualization of the surgical field with an internal perforating method, complete osteotomy with fully preserved intranasal mucosa could be conducted exactly as intended. This intact mucosal lining compensates for the elevated periosteum. Compressive dressing and drainage through a Silastic angio-needle catheter enabled the elimination of dead space. Therefore, precise, reproducible, and predictable osteotomy minimizing the potential for associated complications such as ecchymosis, that is, bruising owing to hemorrhage, could be performed. In this article, we introduce a novel technique for lateral osteotomy with improved visualization. PMID:26848452

    The functional analysis of plant cells at the cellular and subcellular levels requires novel technologies for the directed manipulation of individual cells. Lasers are increasingly exploited for the manipulation of plant cells, enabling the study of biological processes on a subcellular scale including transformation to generate genetically modified plants. In our setup either a picosecond laser operating at 1064 nm wavelength or a continuous wave laser diode emitting at 405 nm are coupled into an inverse microscope. The beams are focused to a spot size of about 1.5 μm and the tobacco cell protoplasts are irradiated. Optoporation is achieved when targeting the laser focal spot at the outermost edge of the plasma membrane. In case of the picosecond laser a single pulse with energy of about 0.4 μJ was sufficient to perforate the plasma membrane enabling the uptake of dye or DNA from the surrounding medium into the cytosol. When the ultraviolet laser diode at a power level of 17 mW is employed an irradiation time of 200 - 500 milliseconds is necessary to enable the uptake of macromolecules. In the presence of an EYFP encoding plasmid with a C-terminal peroxisomal signal sequence in the surrounding medium transient transformation of tobacco protoplasts could be achieved in up to 2% of the optoporated cells. Single cell perforation using this novel optoporation method shows that isolated plant cells can be permeabilized without direct manipulation. This is a valuable procedure for cell-specific applications, particularly where the import of specific molecules into plant cells is required for functional analysis.

    Hepatobiliary and pancreatic ascariasis occur due to migration of the round worm ascaris lumbricoides through the bile duct orifice finally reaching the common bile duct, main pancreatic duct, intrahepatic ducts or gallbladder. These resulted in acute epigastric and right hypochondriac region colicky pain. Ultrasound is the investigation of choice in hepatobiliary ascariasis. We present here sonographic images on four pediatric patients with acute biliary colic. PMID:26690772

    Trauma, oncological resections and pressure sores can cause major soft tissue defects. The evolution of cutaneous, myocutaneous, and fasciocutaneous flaps currently makes possible the restoration of contour and, in many cases, function. This evolution was closely related to the increased understanding of the vascular anatomy of the skin and subcutis and has led to the development of perforator flaps. A perforator flap is a large flap of skin that survives on a single vascular stalk that perforates the muscle, referred to in briefas a 'perforator'. This has its origin in a larger vascular stalk that runs beneath the muscle. The vascular stalk of such a perforator flap can be lengthened by dissecting the perforator from the muscle in continuity with the vessels running beneath the muscle. Moreover, the larger diameter of these vessels facilitates the creation of a vascular anastomosis in the receptor area. By the use of such perforator flaps, proper innervation and a good blood supply to the flap can be combined with less morbidity at the donor site. Important possibilities include the filling of a dorsal (decubitus) defect and breast reconstruction.
