[Unusual cause of acute abdomen in adult patient: gallstone ileus]. / Insolita causa di addome acuto in paziente adulto: l'ileo biliare.

INTRODUCTION: Gallstone ileus is a rare complication of cholecystolithiasis. It causes 1-3% of the mechanical obstructions of the small bowel. It often affects patients between 63 and 85 years old. Pre-operative diagnosis is usually delayed 1-10 days because there is not a specific symptomatology. CASE REPORT: The authors report the case of a 50 year-old man with diagnosis of mechanical obstruction of the small bowel caused by a voluminous gallstone. Ileal occlusion was showed by CT. The patient underwent to one-stage emergency surgery with enterolithotomy, cholecystectomy and duodenal fistula repair. Patient's recovery was regular and he was discharged fourteen days after surgery. DISCUSSION: In our case gallstone ileus was diagnosed with a delay of 5 days. Ultrasonography was not able to show the gallbladder. Diagnosis was made by CT, which is the diagnostic gold standard. CONCLUSION: Patient's performance status influences surgical strategy. In our experience, the patient underwent one-stage surgery because he was considered at low risk. Instead staged procedure with enterolithotomy and delayed cholecystectomy and fistula repair, is performed only in patients at high risk.

[Umbilical primary endometrioma. Case report]. / Endometriosi primitiva ombelicale. Caso clinico.

Umbilical primary endometrioma is a rare extra-uterine localization of endometriosis with a documented neoplastic risk. It is often difficult to distinguish primary umbilical endometriosis from other benign and malignant tumors of the abdominal wall. The Authors report a case of umbilical endometriosis in a 36-year old female. Endometriosis was suspected because of the presence of the typical cyclic bleeding and swelling. Abdominal CT excluded the presence of other endometriotic localizations. The umbilical mass was widely excised together with umbilicus, fascia and peritoneum. The tissue defect was primary closed without prosthetic mesh. Histological examination of the specimen showed the presence of endometrial glands with stromal component, compatible with the diagnosis of endometriosis. The Authors suggest that surgery should be performed in the first 3-4 days of the follicular phase, to minimize the risk of diffusion of endometriotic cells. Moreover, the excision should be wide in order to prevent local recurrence.

[Massive haemoperitoneum due to traumatic rupture of multifocal hepatocarcinoma in the right hepatic lobe. Case report]. / Emoperitoneo massivo da rottura di epatocarcinoma multifocale del lobo destro. Case report.

UNLABELLED: Abdominal blunt trauma is the main cause of death in people younger than 40 years old. The liver injury still represents a challenging problem. Isolated hepatic injury is rare and it occurs more frequentely in polytraumatizated patients and causes massive haemoperitoneum. The Authors report a case of a 83 years-old woman admitted to Emergency Department for syncope due to an active bleeding arising from a rupture of a right hepatic lobe unsuspected tumor. The computer tomography (CT) scans showed a clear pattern of liver laceration of the VI segment with contrast enhancement spreading in the surrounding tissues, and detected a multifocal hepatocarcinoma located in the VI, VII and VIII segments. Patient's haemodinamically unstable conditions suggested an urgent laparotomy. An accurate perihepatic packing with sterile-drape were successfully employed to control liver hemorrage. Temporary abdominal closure, followed by hepatic arteriography and the right hepatic artery embolization, completed the damage control. Re-exploration laparotomy after 72 hours confirmed the definitive haemostasis and the pack removal was performed without complications. CONCLUSIONS: CT plays a leading role in the diagnosis of liver damage. The patient's haemodynamic status is the principal criterion determining conservative or operative therapy in blunt liver injury. The early perihepatic packing followed by artheriographic embolization to stop liver hemorrhage showed efficacy and safety for the patient. The packing performed with sterile-drape is able to avoid removal complications and 72 hours timing for the pack removal is effective to avoid re-bleeding.

[A case of arterial chemoembolization for hepatocellular carcinoma with 11 years of survival]. / Un caso di epatocarcinoma trattato con chemio-embolizzazione arteriosa transcatetere con sopravvivenza di 11 anni.

Hepatocellular carcinoma (HCC) is the most common malignancy of the liver and the third most common cause of cancer mortality worldwide. The major risk of developing HCC is associated with HBV and HCV hepatitis. Liver transplant (LT) is the gold standard for "small" HCC (HCCs) in Child-Pugh class A cirrhotic patients. However its use has been restricted by the severe shortage of donors, so that hepatic resection (HR) is often performed in these patients. In the last two decades image-guided interventional catheterization and ablative regional treatment procedures have revolutionized the therapy of unresectable primary and secondary liver tumors. The Authors present a case of a 61-years old man with Child-Pugh class A HCCs. The age and the previous history of bladder carcinoma made the patient not suitable for LT. The patient refused HR so that transarterial chemoembolization combined to thermo-ablation therapy and oral intake of tamoxifen were proposed. Patient's tolerance to the treatments has been good. During 11-year follow-up there was earlier intrahepatic progression of the tumor followed by reduction in size and number of the lesions. In spite of the scarce prognosis, chemoembolization and immunotherapy allowed to achieve a satisfactory local control of disease in our patient and guaranteed a good quality of life at long-term follow-up.

[A case of uterine carcinosarcoma]. / Carcinosarcoma dell'utero: descrizione di un caso clinico.

Uterine carcinosarcoma is a highly aggressive neoplasm with tendency to early recurrence and/or metastasis. The neoplasia has both epithelial and stromal malignant components. Clinically, it is characterized by a postmenopausal metrorrhagia, associated sometimes with abdominal pain. The Authors describe a case of carcinosarcoma in a 82-year old woman with a vaginal bleeding since 10 months and an ingravescent hypochromic anemia. The RMN of the abdomen and pelvis showed a mass occupying the whole uterine lumen, without signs of pelvic diffusion. A bilateral hystero-oophorectomy was performed; the patient's critical conditions and a high anaesthesiological risk advised us not to perform a bilateral pelvic lymphadenectomy with aortic sampling. Six months after operation, a clinical follow-up with a total-body CT didn't show any sign of local recurrence and/or distant metastasis. From the analysis of this case report and from the data of the literature some important considerations can be done: a) gynecologic check up in post-menopausal women with associated risk factors (obesity and hypertension) can allow an early diagnosis also in asymptomatic patients; b) sovrapubic and transvaginal US, abdomino-pelvic CT and MRI are essential for a correct clinical staging; c) surgical excision followed by the histological examination of the specimen is mandatory to establish a correct diagnosis.
