Small bowel intussussception due to metastatic melanoma of unknown primary site. Case report.

Malignant melanoma is characterized by metastases also to the gastrointestinal tract, especially in the small bowel. The diagnosis is often delayed because unspecific clinical presentation (frequently as chronic iron deficiency anemia, rectal bleeding or intestinal obstruction). We present a case of melanoma of unknown primary site, with clinical presentation of intestinal obstruction. A segmental resection of the ileum was performed including mesentery with lymph nodes. Histology revealed metastatic melanoma from unknown primary. PET and MRI confirmed disseminated disease without brain metastasis.

Biliodigestive fistulae and gallstone ileus: diagnostic and therapeutic considerations. Our experience.

The biliodigestive fistula is not a rare affection in the context of acute pathology of the gastrointestinal tract. It often affects patients between 63 and 85 years old , particularly the female sex, and the most common cause is acute or chronic cholecystolithiasis. Open issues are the delayed in the pre-operative diagnosis, and controversies exist regarding the best surgical approach. The choice of treatment options is influenced by the age of the patients and their clinical conditions and also by the presence of comorbidities and of a delayed right diagnosis. In the 1 to 3% of cases, the biliodigestive fistula presents a gallstone ileus as complication, whose diagnosis is particularly difficult for the lack of specific signs and symptoms. The contrast-enhanced CT is considered the gold standard for a specific pre-operative diagnosis, as it directly shows the fistula. Surgical treatments include one-stage procedure or two-stage procedure. Many studies seem to favor a deferred definitive procedure. The Authors describe 4 cases: in 3 cases, women between 70 and 80 years old presenting an history of recurrent cholecystitis, in 2 cases, and in 1 case presenting a bowel obstruction; in 1 case a 50-years-old man, with no significant past medical history, presenting a bowel obstruction. The Authors have performed in the 2 cases of gallstone ileus an enterolithotomy with cholecysto-duodenal fistula repair and cholecystectomy, in one-stage, and this has been possible because of the good clinical conditions of the patients and their low operative risk. In the case of fistula without the complication of gallstone ileus, the treatment approach has been cholecysto-gastric fistula closure with a gastroplastic using separate stitches and cholecystectomy, in one-stage. We are in agreement with data in the literature regarding the delay into the diagnosis of biliodigestive fistula and with the importance to suspect it or gallstone ileus presence, although the clinical presentation is extremely non-specific. In our experience, cholangiopancreatography-CT and CECT have made easier the pre-operative diagnosis and so reducing the delay of the treatment.

Technique and outcomes about a new laparoscopic procedure: the Pelvic Organ Prolapse Suspension (POPS).

Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simpler than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology.

Risk management in surgery.

Malpractice is the responsible for the greatest number of legal claims. At the present time, legal actions against physicians in Italy are 15,000 per year, and a stunning increase about costs to refund patients injured by therapeutic and diagnostic errors is expected. The method for the medical prevention is "Risk Management", that is the setting-up of organizational instruments, methods and actions that enable the measurement or estimation of medical risk; it allows to develop strategies to govern and reduce medical error. In the present work, the reconstruction about the history of risk management in Italy was carried out. After then the latest initiatives undertaken by Italy about the issue of risk management were examined.

Single-incision laparoscopic appendectomy is comparable to conventional laparoscopic and laparotomic appendectomy: our single center single surgeon experience.

Several studies have demonstrated the clinical and technical benefits of the laparoscopic surgery for complicated and uncomplicated appendicitis. Our retrospective study included 12 patient who underwent SILS appendectomy (SILS-A), 14 who received conventional laparoscopic surgery (VL-A), and 12 who received laparotomic appendectomy (OA); performed in all cases by the same surgeon (C.F.). The aim of this study was the comparison between this three different surgical techniques on same features: post operative leukocytosis, post operative pain, need abdominal drainage, esthetic viewpoint, incidence of complication, hospital stay. The results showed no significant differences between SILS-A and VLS-A, while an evident improvement shows versus O-A, even though not statistically significative. SILS was more effective in decreasing the risk of postoperative wound infection.

Liver resection for hemoperitoneum caused by spontaneous rupture of unrecognized hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

Cholecystectomy by single incision laparoscopic surgery (SILS): early experience and technique standardization.

Single Incision Laparoscopic Surgery (SILS) is a recent surgical technique, first described in the 1990s. Its aim is to optimize the esthetic result offered by laparoscopy by minimizing the number of abdominal incisions. Various preliminary studies have been carried out on the application of SILS, especially in cholecystectomy and appendectomy. This study evaluates the preliminary results of cholecystectomy by SILS (SILS™ Port) conducted between October 2009 and February 2011 on 21 patients (4 men and 17 women) with a mean age of 49.9 years and a mean Body Mass Index (BMI) of 22.8. All patients were treated by the same team, which had previously undergone six months' simulator training. There were two main selection criteria, both evaluated intraoperatively: absence of adhesions and of significant inflammatory sequelae from previous cholecystitis; and suitable distance between gallbladder and SILS access port. Conversion to traditional laparoscopy was necessary in just two cases, while an accessory trocar was introduced in another two cases. Conversion to open surgery was not necessary in any case. One case of SILS cholecystectomy was complicated by postoperative bile leakage, which was treated conservatively, as the fistula had a low output. The mean duration of hospitalization was 3.6 days. This preliminary experience led us to conclude that SILS is safe and highly satisfactory in the postoperative phase, thanks to the reduced need for painkillers and the improved esthetic result.

[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 possible cause of misdiagnosis in tumors of the axilla: schwannoma of the brachial plexus]. / Una possibile causa di errore nella diagnosi differenziale delle formazioni ascellari: lo schwannoma asintomatico dei tronchi del plesso brachiale.

The Authors report a rare case of a 57 years old man affected by a left radial nerve schwannoma that occurred as an asymptomatic lesion of the axilla. At clinical examination the lump was undistinguishable from the most common axillary lymphadenopathy. A lymphoadenopathy was erroneously diagnosed with ultrasonography (US). This mistake was due to the low specificity of the instrumental methodology and to the rarity of an asymptomatic schwannoma of the infraclavicular brachial plexus. The neoplasia was excised without using the microscope. In the early post-operative follow up, a "falling" attitude of the wrist, the hand and the fingers appeared, peculiar for a lesion of the radial nerve. Furthermore a hypoaesthesia of the skin of first finger and of the first interosseus space was associated. The sensitive and motor electromyography showed a radial nerve suffering. The "stupor" of the nerve trunk was treated with steroid therapy for 7 days and the patient underwent to some series of neuro-rehabilitative physical therapy for 12 weeks. The postoperative total body CT, showed that the lesion was unique: therefore it was possible to exclude the diagnosis of neurofibromatosis. After 28 months electromyography and axillary US were performed showing the complete resolution of the motor and sensitive deficit and the absence of local recurrence.

[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.
