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

    To clarify the relationship between the pattern of cholecystolithiasis and the gross features of segmental adenomyomatosis of the gallbladder. Fifty-five consecutive patients with segmental adenomyomatosis with calcified gallbladder stones defined on CT were retrospectively analyzed in terms of (i) stone location (fundal vs. neck compartment) and (ii) size of the largest stone as a function of the extent of segmental mural thickening (type A, limited at the narrow segment; type B, partially extended in the fundal direction; type C, involving the entire fundal compartment). The extent of segmental mural thickening in patients with cholecystolithiasis was compared with a control group (n = 48) lacking stones. Stones were found more frequently in the fundal compartment in 48 patients compared to the neck compartment in 12 patients (p<0.001). The mean size of the largest stone in type C (5.4 ± 4.9 mm) was larger than in type A (2.3 ± 2.2 mm) (p=0.033). In patients with cholecystolithiasis, type C segmental thickening was predominant (69%) compared to the control group (42%) (p=0.012). In addition to a higher prevalence of stones, a wide extent of mural thickening combined with large stone size in the fundal compartment suggests the contribution of segmental adenomyomatosis to stone formation and chronic inflammation.

    The objective of this study was to analyze gallbladder stones for direct evidence of a relationship between Clonorchis sinensis infection and gallbladder stones formation. We investigated one hundred eighty-three gallbladder stones for the presence of Clonorchis sinensis eggs using microscopy, and analyzed their composition using Fourier transform infrared spectroscopy. We confirmed the presence of Clonorchis sinensis eggs in the gallbladder stones using real-time fluorescent PCR and scanning electron microscopy. Clonorchis sinensis eggs were detected in 122 of 183 gallbladder stones based on morphologic characteristics and results from real-time fluorescent PCR. The proportion of pigment stones, cholesterol stones and mixed gallstones in the egg-positive stones was 79.5% (97/122), 3.3% (4/122) and 17.2% (21/122), respectively, while 29.5% (18/61), 31.1% (19/61) and 39.3% (24/61) in the egg-negative stones. The proportion of pigment stone in the Clonorchis sinensis egg-positive stones was higher than in egg-negative stones (PClonorchis sinensis eggs were visible (×400) showing a distinct morphology. Many eggs were wrapped with surrounding particles, and in some, muskmelon wrinkles was seen on the surface of the eggs. Also visible were pieces of texture shed from some of the eggs. Some eggs were depressed or without operculum while most eggs were adhered to or wrapped with amorphous particles or mucoid matter (×3000). Clonorchis sinensis eggs were detected in the gallbladder stones which suggests an association between Clonorchis sinensis infection and gallbladder stones formation, especially pigment stones.

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

    The etiopathogenesis of bile duct lesion in primary biliary cirrhosis is unknown, though the participation of bacteria and/or their components and products is suspected. In this study, we tried to detect and identify bacteria in the bile of patients with primary biliary cirrhosis by polymerase chain reaction using universal bacterial primers of the 16S ribosomal RNA gene. Gallbladder bile samples from 15 patients with primary biliary cirrhosis, 5 with primary sclerosing cholangitis, 5 with hepatitis C virus-related liver cirrhosis, 11 with cholecystolithiasis, and from 12 normal adult gallbladders were used. In addition to the culture study, partial bacterial 16S ribosomal RNA gene was amplified by polymerase chain reaction (PCR) taking advantage of universal primers that can amplify the gene of almost all bacterial species, and the amplicons were cloned and sequenced. Sequence homology with specific bacterial species was analyzed by database research. Bacterial contamination at every step of the bile sampling, DNA extraction and PCR study was avoided. Furthermore, to confirm whether bacterial DNA is detectable in liver explants, the same analysis was performed using 10 liver explants of patients with primary biliary cirrhosis. In primary biliary cirrhosis, 75% (p<0.0001) of 100 clones were identified as so-called gram-positive cocci while these cocci were positive in only 5% in cholecystolithiasis (p<0.0001). In cholecystolithiasis gram-negative rods were predominant instead. One bacterial species detected in a normal adult was not related to those detected in primary biliary cirrhosis and cholecystolithiasis patients. No bacterial DNA was detected by PCR amplification in 10 liver explants of patients with primary biliary cirrhosis. The present results raise several possible roles of gram-positive bacteria in bile in the etiopathogenesis of primary biliary cirrhosis. However, these results could also reflect an epiphenomenon due to decreased bile flow in the

    Full Text Available Available evidence of the relationship between cholelithiasis, cholecystectomy, and risk of liver cancer and hence we conducted a meta-analysis to investigate the relationships. PubMed, EMBASE, and ISI Web of Knowledge were searched to identify all published cohort studies and case-control studies that evaluated the relationships of cholelithiasis, cholecystectomy and risk of liver cancer and single-cohort studies which evaluated the incidence of liver cancer among patients who understood cholecystectomy (up to February 2013. Comprehensive meta-analysis software was used for meta-analysis. A total of 11 observational studies (six cohort studies and five case-control studies were included in this meta-analysis. The result from meta-analysis showed that cholecystectomy (risk ratio [RR]: 1.59, 95% confidence interval [CI]: 1.01-2.51, I2 = 72% and cholecystolithiasis (RR: 5.40, 95% CI: 3.69-7.89, I2 = 93% was associated with more liver cancer, especially for intrahepatic cholangiocarcinoma (ICC (cholecystectomy: RR: 3.51, 95% CI: 1.84-6.71, I2 = 26%; cholecystolithiasis: RR: 11.06, 95% CI: 6.99-17.52, I2 = 0%. The pooled standardized incidence rates (SIR of liver cancer in patients who understood cholecystectomy showed cholecystectomy might increase the incidence of liver cancer (SIR: 1.57, 95% CI: 1.13-2.20, I2 = 15%. Based on the results of the meta-analysis, cholecystectomy and cholecystolithiasis seemed to be involved in the development of liver cancer, especially for ICC. However, most available studies were case-control studies and short-term cohort studies, so the future studies should more long-term cohort studies should be well-conducted to evaluate the long-term relationship.

    The present study reports on 51 patients with symptomatic cholecystolithiasis, who accordingly underwent extracorporeal shock-wave lithotripsy (ESWL). In all cases, computed tomography (CT) was performed prior to and after the therapeutic procedure to delineate changes in gall-bladder morphology. Slight edematous thickening of the gall-bladder wall was found in 15 patients. One patient presented a rupture of the gall-bladder with formation of a bilioma in the adjacent liver tissue. In case of calcific concrements, CT revealed a characteristic pattern of fragment distribution following shock-wave treatment, and fragments of various sizes exhibited distinct adhesion to the gall-bladder wall.

    2013-09-01

    Full Text Available Surgical removal of the gallbladder is indicated in nearly all cases of complicated acute cholecystitis. In the 1990s, laparoscopic cholecystectomy became the method of choice in the treatment of cholecystolithiasis. Due to a large inflammatory reaction in the course of acute inflammation, a laparoscopic procedure is conducted in technically difficult conditions and entails the risk of complications. The aim of this paper was: 1 to analyze ultrasound images in acute cholecystitis; 2 to specify the most common causes of conversion from the laparoscopic method to open laparotomy; 3 to determine the degree to which the necessity for such a conversion may be predicted with the help of ultrasound examinations. Material and methods: In 1993–2011, in the Second Department and Clinic of General, Gastroenterological and Oncological Surgery of the Medical University in Lublin, 5,596 cholecystectomies were performed including 4,105 laparoscopic procedures that constituted 73.4% of all cholecystectomies. Five hundred and forty-two patients (13.2% were qualified for laparoscopic procedure despite manifesting typical symptoms of acute cholecystitis in ultrasound examination, which comprise: thickening of the gallbladder wall of > 3 mm, inflammatory infiltration in the Calot’s triangle region, gallbladder filled with stagnated or purulent contents and mural or intramural effusion. Results: In the group of operated patients, the conversion was necessary in 130 patients, i.e. in 24% of cases in comparison with 3.8% of patients with uncomplicated cholecystolithiasis (without the signs of inflammation. The conversion most frequently occurred when the assessment of the anatomical structures of the Calot’s triangle was rendered more difficult due to local inflammatory process, mural effusion and thickening of the gallbladder wall of >5 mm. The remaining changes occurred more rarely. Conclusions: Based on imaging scans, the most common causes of conversion

    The initial goal in treatment for infantile cholestasis is to exclude surgical cholestasis, especially biliary atresia (BA). In this study, we retrospectively reviewed the diagnostic course of infantile cholestasis. Between 2000 and 2009, a total of 44 infants with cholestasis were referred to our department. The median age at admission was 54 days (range: 0-143 days). The medical charts of these infants were reviewed. The initial diagnostic approach was ultrasonography followed by the qualitative detection of bilirubin in stool. The 35 infants with acholic stool and/or a small or absent gallbladder on ultrasonography were subsequently examined by hepatobiliary scintigraphy (HBS). Twenty-nine infants with negative scintigraphy findings underwent intraoperative cholangiography (lOC), and BA was finally confirmed in 24 of 44. A choledochal cyst was noted in 2, Alagille syndrome in 2, cytomegalovirus infection in 2, panhypopituitarism in 2, multiple hemangiomas of the liver in 1, and cholecystolithiasis in 1. The remaining 10 infants were diagnosed as having neonatal hepatitis. The sensitivity and specificity of HBS for BA were 100% and 54.5%, respectively. HBS is a useful modality for detection of BA with a sensitivity of 100%. The indication for IOC should depend on these scan results. (author)

    We recently developed an oval-shaped E•Z Access device designed exclusively for use with the LAP PROTECTOR™ Oval type device (Hakko Co. Ltd., Tokyo, Japan). The transverse abdominal opening diameter made by round-shaped (Alexis® Wound Retractor, Applied Medical, Rancho Santa Margarita, CA; and LAP PROTECTOR™ Round type) and oval-shaped (LAP PROTECTOR™ Oval type) wound retractors was measured and compared in 5 patients with cholecystolithiasis. Each device was placed through a single 25-mm longitudinal umbilical incision, and the length of trocar separation was compared. LESS cholecystectomy was then performed using the oval-shaped E•Z ACCESS/LAP PROTECTOR™. The transverse abdominal opening diameter was maximized with the LAP PROTECTOR™ Oval type device. The average distance between the working-ports for the glove method, round-shaped, and oval-shaped E•Z ACCESS/LAP PROTECTOR™ devices in the 25-mm umbilical incisions were 20 ± 0.8 mm, 24 ± 1.5 mm, and 35 ± 0.8 mm, respectively. Wider trocar separation was achieved using the oval-shaped device, making the surgical procedures easier to perform. No perioperative port-related or surgical complications were observed. LESS cholecystectomy using the E•Z ACCESS Oval type device was found to be technically feasible. The Oval type device appears to allow for wider trocar separation, thereby reducing stress on the surgeon, ensuring patient safety, and providing cosmetic benefits.

    We investigated 58 cases of cholecystolithiasis including 8 cases of choledocholithiasis treated with laparoscopic cholecystectomy. All patients received spiral CT scanning with drip infusion cholangiography (DIC-SCT), and 16 patients received endoscopic retrograde cholangiography (ERC), and the detection rates of the gallbladder, the bile duct and the cystic duct were compared. The gallbladder could be seen in 86.2% of cases with DIC-SCT and in 63.8% of cases with conventional DIC. The junction between the cystic duct and the common bile duct could be seen in 18 of 58 cases with DIC and in 49 of 58 cases with DIC-SCT. The DIC-SCT showed significantly superior anatomical datails compared with images with conventional DIC. A comparison of DIC, ERC and DIC-SCT revealed that the junction between the cystic duct and the common bile duct could be identified in 14 of 16 cases undergoing ERC, in 13 of 16 cases receiving DIC-SCT and in 4 of 16 cases receiving DIC. Significant differences were noted among DIC-SCT, ERC and conventional DIC. We concluded that DIC-SCT is easy, non-invasive and useful for the preoperative assessment of laparoscopic cholecystectomy and also helpful for avoiding damage to the bile duct. (author)

    Background: Although the practice of preoperative testing of ABO group and Rh (D) type for elective cholecystectomy has deep historical roots, it is not evidence-based. We aimed to assess the preoperative blood group and save testing practice for a cohort of patients subjected to elective laparoscopic cholecystectomy for symptomatic cholecystolithiasis between January 2010 and October 2014. Methods: National Health Service (NHS) hospital based, surgical procedure-specific, retrospective study was conducted. A final group consisted of 2,079 adult patients. We estimated the incidence of perioperative blood transfusion attributable to laparoscopic cholecystectomy. The results of eight other studies are presented. Results: A preoperative blood group and save test was performed in 907 patients (43.6%), whereas cross-matching was documented in 28 patients (3.1%). None required an intraoperative blood transfusion. Twelve patients (0.58%) underwent blood transfusion postoperatively following laparoscopic cholecystectomy, of which ten were transfused due to severe intra-abdominal bleeding (0.48%). There were no deaths. Conclusions: The likelihood of blood transfusion attributable to elective laparoscopic cholecystectomy is 1:200. A routine preoperative blood group and save testing is unnecessary. It neither alters the management of severe hypovolemia, secondary to perioperative bleeding, nor does it lead to better outcomes.

    Laparoscopic cholecystotomy (LCT) with subsequent extraction of gallstones and primary closure of the gallbladder has been introduced as an alternative therapy for patients with cholecystolithiasis and preserved gallbladder function. However, stone recurrence has to be considered as a major drawback that might be related to lithogenic factors of gallbladder bile or the composition of gallbladder stones. Therefore, these were studied in relation to stone recurrence within an observation period of 1 to 5 years (median, 3.6 years) in 50 patients after LCT. The concentrations of total and individual bile acids, phospholipids, cholesterol, total lipids, mucin, protein, and the cholesterol saturation indices in gallbladder bile were not significantly different between 10 patients with and 40 patients without stone recurrence. However, the crystal observation time was significantly (P < .02) shorter (range, 1-2 days; median, 1.5) in the bile of patients with stone recurrence compared to those without (range, 1-21 days, median 3.5). Moreover, all 10 stone recurrences were observed in the 28 patients with a crystal observation time in the bile of less than or equal to 2 days (approximate annual risk: 12%-15%), and no recurrences were observed in the 22 patients with a crystal observation time greater than 2 days (P < .0001) or in patients with pigment stones. The rapid formation of cholesterol monohydrate crystals in bile seems to be the major risk factor for recurrent stones after LCT. These are most likely cholesterol stones and, therefore, are amenable to oral bile-acid prevention or treatment.

    The purpose of this study was the comparison of technically improved single-shot magnetic resonance cholangiopancreatography (MRCP) sequences with standard single-shot rapid acquisition with relaxation enhancement (RARE) and half-Fourier acquired single-shot turbo spin-echo (HASTE) sequences in evaluating the normal and abnormal biliary duct system. The bile duct system of 45 patients was prospectively investigated on a 1.5-T MRI system. The investigation was performed with RARE and HASTE MR cholangiography sequences with standard and high spatial resolutions, and with a delayed-echo half-Fourier RARE (HASTE) sequence. Findings of the improved MRCP sequences were compared with the standard MRCP sequences. The level of confidence in assessing the diagnosis was divided into five groups. The Wilcoxon signed-rank test at a level of p<0.05 was applied. In 15 patients no pathology was found. The MRCP showed stenoses of the bile duct system in 10 patients and choledocholithiasis and cholecystolithiasis in 16 patients. In 12 patients a dilatation of the bile duct system was found. Comparison of the low- and high spatial resolution sequences and the short and long TE times of the half-Fourier RARE (HASTE) sequence revealed no statistically significant differences regarding accuracy of the examination. The diagnostic confidence level in assessing normal or pathological findings for the high-resolution RARE and half-Fourier RARE (HASTE) was significantly better than for the standard sequences. For the delayed-echo half-Fourier RARE (HASTE) sequence no statistically significant difference was seen. The high-resolution RARE and half-Fourier RARE (HASTE) sequences had a higher confidence level, but there was no significant difference in diagnosis in terms of detection and assessment of pathological changes in the biliary duct system compared with standard sequences.

    localized scleroderma was seen in 3 patients and generalized localized scleroderma in one case. All patients had a histological picture consistent with scleroderma, negative ANA and ENA antibodies (Table 1, Figure 1). A 66-year-old woman presented with a 10 months history of sclerodermatous plaques on her neck, trunk, and upper and lower extremities. The skin on her breasts and cheeks was diffusely indurated. Examination showed thrombocytopenia, elevated transaminases, Cancer antigen 19-9 (Ca 19-9), thyroid stimulating hormone (TSH), and anti-thyroid peroxidase antibodies, dysmotility of the lower part of esophagus, hepatosplenomegaly, cholecystolithiasis, and benign polyps of colon. She was given prednisone 40 mg/day but did not return for follow up. After 6 months she was diagnosed with cholangiogenic carcinoma with metastatic disease and died shortly afterwards. A 74-year-old woman had localized scleroderma on the trunk for three years. She was treated with procaine penicillin for positive borrelia Immunoglobulin M (IgM) antibodies. Her condition worsened suddenly with confluent scleroderma plaques on her trunk, extremities, and genital region, and vasoneurosis on her lower extremities; she was started on prednisone 35 mg/day. Examination revealed endometrial cancer. The patient underwent a hysterectomy, adnexectomy, and radiotherapy with curative effect. Scleroderma patches softened with residual hyperpigmentation, and prednisone was stopped two years later. A 80-year-old man had a month-long history of diffuse thickening and toughening of the skin on the forearms and lower legs and scleroderma patches on the thighs and shins. Examination revealed prostate adenocarcinoma, and therapy with antiandrogen bicalutamide and prednisone 15 mg/day was started. Two years after the diagnosis he continues with bicalutamide treatment, prednisone 5 mg q.a.d. and has residual toughening of the skin on his lower legs. A 62-year-old woman with seronegative rheumatoid arthritis presented

    Full Text Available PURPOSE: Establish the prevalence of Helicobacter spp in chronic cholecystitis and its correlation with the gallbladder's histological findings. METHODS: 100 patients were operated for chronic cholecystitis with cholecystolithiasis. In pathological examination of the gallbladder, were evaluated the presence of metaplasia, dysplasia, lymphoid follicles, anaplasia and tumors that might be related to the presence of Helicobacter plus the presence of the bacilli Giemsa? by optical microscopy. From the DNA extracted from the gallbladder's bile, PCR was performed by using specific primers for the identification of Helicobacter spp with amplification of the 400bp segment of rRNA gene16S, with positive control DNA from Helicobacter pylori. All the cases negative for isolation of genetic material were excluded. The cases of PCRΘ and GiemsaΘ were used as negative control group. The histological findings were compared to the presence of bacilli and PCR data using a chi-square and Fisher's Exact test (CI = 95.0%, p OBJETIVO: Estabelecer a prevalência do Helicobacter spp nos doentes com colecistopatia crônica calculosa e correlacioná-la com as alterações histológicas da vesícula biliar.

    Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included. Patients received a pre-operative questionnaire on medical history and social situation when informed consent on surgery and participation in the study was obtained. Exclusion criteria were patients suffering from acute cholecystitis or any type of cancer; having a BMI >40 kg/m 2 ; needing conversion to open cholecystectomy or an intraoperative drainage; and non-German speakers. Surgery was performed laparoscopically. Both surgeon and patient filled in a postoperative questionnaire. The surgeon's questionnaire listed medical and technical information, and the patients' questionnaire listed medical information, satisfaction with the treatment and willingness to be released on the same day. These data from both questionnaires were grouped into social and medical factors and analysed on their influence upon willingness to accept an ambulatory procedure. No outpatient follow-up apart from checking for readmission to our hospital within 1 month after discharge was performed. Of the 100 participants, one-third was male. More than two-thirds were Swiss citizens. Only one participant was ineligible for rapid release evaluation due to need of a drainage. Among the social factors contributing to the acceptability of ambulatory care, we found nationality to be relevant; Swiss citizens preferred an inpatient procedure, whereas non-Swiss citizens were significantly more willing to return home on the same day. Household size, sex and age did not correlate with a preference for
