Hepatic Sarcoidosis Mimicking Hilar Cholangiocarcinoma: Case Report and Review of the Literature

Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. Hepatic involvement was reported in about 11% of patients with sarcoidosis. However, cases of sarcoidosis in which the granuloma is solitary and limited in the liver are very rare. A 51-year-old woman with tumors in the liver underwent extended left lobectomy with caudate lobectomy and bile duct resection. The tumor was located between segment 4 and the hilar region. Some daughter nodules were found in the left lobe, which were regarded as intrahepatic metastasis. Our case displayed clinical and radiologically distinct findings, which are very similar to those of hilar cholangiocarcinoma restricted to the liver. This report demonstrates that sarcoidosis can show solitary hepatic involvement in the absence of thoracic lymphadenopathy. In such a case, it is difficult to distinguish the diagnosis from other malignant neoplasms. In conclusion, the diagnosis of hepatic sarcoidosis has to be made through prudent and comprehensive investigations that include a full clinical history of sarcoidosis in other organs. Despite utilizing several detailed diagnostic modalities, the definitive diagnosis of cases of solitary sarcoidosis may remain difficult. In these cases, surgical treatment including liver resection should be considered in order to avoid missing a suitable opportunity for treatment

Pneumatosis cystoides intestinalis associated with massive free air mimicking perforated diffuse peritonitis

While pneumatosis cystoides intestinalis (PCI) is a rare disease entity associated with a wide variety of gastrointestinal and non-gastrointestinal disorders, PCI associated with massive intra- and retroperitoneal free air is extremely uncommon, and is difficult to diagnose differentially from perforated peritonitis. We present two cases of PCI associated with massive peritoneal free air and/or retroperitoneal air that mimicked perforated peritonitis. These cases highlight the clinical importance of PCI that mimics perforated peritonitis, which requires emergency surgery. Preoperative imaging modalities and diagnostic laparoscopy are useful to make an accurate diagnosis

Effect of pancrelipase in preventing pancreatic dysfunction after pancreaticoduodenectomy

OBJECTIVES: Patients who have undergone pancreaticoduodenectomy (PD) may experience a long-term decrease in quality of life because of postoperative pancreatic dysfunction (such as digestive and absorption disorders) and fatty liver as a result of combined resection of the duodenum, gallbladder, and bile duct. The present study investigated the usefulness of pancrelipase for the prevention of pancreatic dysfunction after PD. METHODS: The data from 73 patients who underwent PD in a single institution were analyzed. Patients who underwent PD during 2007–2011 were administered the low-titer pancreatic enzyme preparations berizym(®) and pancreatin(®) (first period group), while patients who underwent PD during 2012–2017 were administered the high-titer pancreatic enzyme preparation pancrelipase (second period group). The following measures of the nutrition status were examined before and after PD: serum albumin concentration, total lymphocyte count, serum total cholesterol concentration, body mass index, controlling nutrition status (CONUT) index, Onodera’s prognostic nutrition index (PNI), and liver computed tomography values. RESULTS: The second period group had significantly higher serum albumin concentrations at 3 and 6 months postoperatively, serum total cholesterol concentrations at 1 month postoperatively, and Onodera’s PNI values at 3 and 6 months postoperatively than the first period group. The CONUT index values at 6 months after PD were significantly lower in the second period group than in the first period group. CONCLUSIONS: Pancrelipase is useful in improving the nutrition status and preventing fatty liver after PD
