Hepatopancreatobiliary manifestations and complications associated with inflammatory bowel disease
Abstract: Diseases involving the hepatopancreatobiliary (HPB) system are frequently encountered in patients with inflammatory bowel disease (IBD). Hepatobiliary manifestations constitute some of the most common extraintestinal manifestations of IBD. They appear to occur with similar frequency in patients with Crohn's disease or ulcerative colitis. HPB manifestations may occur in following settings: 1) disease possibly associated with a shared pathogenetic mechanism with IBD including primary sclerosing cholangitis (PSC), small-duct PSC/pericholangitis and PSC/autoimmune hepatitis overlap, acute and chronic pancreatitis related to IBD; 2) diseases which parallel structural and physiological changes seen with IBD, including cholelithiasis, portal vein thrombosis, and hepatic abscess; and 3) ......

Short- and Long-Term Surgical Follow-Up of the Postbariatric Surgery Patient
Follow-up of the large numbers of patients undergoing bariatric surgery poses problems for surgical programs and for internists who care for morbidly obese patients. Early surgical follow up is concentrated on the perioperative period to ensure healing and care for any surgical complications. It is especially important to treat persistent vomiting to avoid thiamine deficiency. Subsequently, monitoring weight loss and resolution of comorbidities assumes more importance. Identification and management of nutritional deficiencies and other unwanted consequences of surgery may become the responsibility of internists if the patient no longer attends the office of the operating surgeon. The long-term goal is to avoid weight regain and deficiencies, especially of protein, iron and vitamin B12, and......

Typhoid fever bacteria collect on gallstones to perpetuate disease
A new study suggests that the bacteria that cause typhoid fever collect in tiny but persistent communities on gallstones, making the infection particularly hard to fight in so-called "carriers" -- people who have the disease but show no symptoms. Humans who harbor these bacterial communities in their gallbladders, even without symptoms, are able to infect others with active typhoid fever, especially in developing areas of the world with poor sanitation.

Pure natural orifice transluminal endoscopic surgery (NOTES) cholecystectomy
Abstract Enthusiasm for natural orifice transluminal endoscopic surgery (NOTES) has been partly tempered by the reality that most NOTES
procedures to date have been laparoscopically assisted. After safely performing transvaginal cholecystectomy in an IACUC-approved
porcine model, the authors embarked on an institution review board (IRB)-approved protocol for ultimate performance of pure
NOTES cholecystectomy in humans. They describe their experience performing a true NOTES transvaginal cholecystectomy after
safely accomplishing three laparoscopically assisted or hybrid procedures in humans. One of the patients was a 35-year-old
woman presenting with symptoms of biliary colic. Ultrasound confirmed gallstones, and her liver enzymes were normal. Pneumoperitoneum

Plasma asymmetric dimethylarginine concentrations in sickle cell disease are related to the hemolytic phenotype.
Authors: Landburg PP, Teerlink T, Biemond BJ, Brandjes DP, Muskiet FA, Duits AJ, Schnog JB,
Asymmetric dimethylarginine (ADMA) is associated with pulmonary hypertension (PHT) in sickle cell disease (SCD). We studied the relationship of ADMA to other SCD-related complications. Plasma ADMA and associated parameters were determined in 52 HbSS/HbSbeta(0)-thalassemia and 24 HbSC/HbSbeta(+)-thalassemia patients. As expected ADMA levels were higher in HbSS/HbSbeta(0)-thalassemia patients with PHT (p=0.018), but also in those with other hemolysis-associated complications such as leg ulcers (p=0.012), cholelithiasis (p=0.008) and priapism (p=0.02) compared with counterparts without these complications. ADMA levels did not differ between patients with and without other disease related complicat......

Laparoscopic cholecystectomy for acute cholecystitis should be performed by a laparoscopic surgeon
Conclusions Patients who present with acute cholecystitis have a greater chance of a laparoscopically completed cholecystectomy if operated
on by a laparoscopy-oriented surgeon.

Detection of bacterial DNA in acute and chronic cholecystitis
The incidence of bacterbilia in cholelithiasis remains controversial. The positivity of cultures ranges from 0 to 73 per cent. The aim of this study was to employ the polymerase chain reaction (PCR) to detect bacterial DNA in gallbladder bile extracted during elective laparoscopic cholecystectomy, and to compare PCR findings with those of bile culture.Bile samples from 84 laparoscopic cholecystectomies were collected for culture and PCR analysis.Positive results for bacterbilia were found in 42 (50 per cent) of 84 patients by PCR but in only 16 patients (19 per cent) by culture (P < 0·001). Agreement between the two methods was seen in 44 samples (52 per cent), which were negative in 35 cases. Pathological examination showed chronic cholecystitis in 69 cases (82 per cent) and acute cholec......

[Diseases of the hepatobiliary system as a cause of acute abdomen.]
Authors: Schima W, Kölblinger C, Eisenhuber-Stadler E, Kulinna-Cosentini C, Ba-Ssalamah A
Diseases of the liver and biliary system are common causes of acute abdominal pain and gallstone disease predisposes to cholecystitis and cholangiolithiasis. Sonography is the method of choice for the assessment of cholecystitis, whereas magnetic resonance cholangiopancreaticography (MRCP) is the standard technique to detect stones in the common bile duct. Multi-detector computed tomography (MDCT) is ideal for detection of associated complications, including abscess formation and gall stone ileus. Pyogenic, amebic and fungal liver abscesses are reliably diagnosed with MDCT which can also be used for interventional radiologic therapy of liver abscesses by percutaneous aspiration or drainage pr......

Comparison of different MRCP techniques for the depiction of biliary complications after liver transplantation
Conclusion Our results underline the value of different MRCP sequence types for the depiction of biliary lesions. A clinical protocol

Decreased NPC1L1 expression in the liver from Chinese female gallstone patients
Conclusions: The decreased hepatic NPC1L1 levels in female GS might indicate a downregulated reabsorption of biliary cholesterol in the liver, which, in turn, leads to the cholesterol supersaturation of bile. Our data are consistent with the possibility that hepatic NPC1L1 may be mediated by SREBP2. (Source: Lipids in Health and Disease)...
