Objective: Umbilical and epigastric hernias are relatively frequent amounting to about 10% of all primary hernias. The aim of this study was to evaluate the efficacy and safety of laparoscopic primary ventral hernia repair., Material and Methods: From January 2002 through July 2007 a total of 23 consecutive patients were treated by laparoscopy for primary ventral hernia. Main demographics, intraoperative and postoperative data were collected., Results: There were 14 males and 9 females with a mean age of 53.1 yrs (range 28-70 yrs). Mean body mass index was 25.2 kg/m2 (range 19.4 - 35.2). Fifteen patients had an umbilical hernia, 6 patients had an epigastric hernia and 2 a Spigelian hernia. Mean defect size was 8,4 cm2 (range 1.7 - 81.6). Mean mesh size was 115.9 cm2 (range 62.8-310.8). Mean operating time was 76.1 min (range 50-130). Mean hospital stay was 3,4 days (range 2-8). The median postoperative pain score (evaluated by a visual analog scale - VAS) was 2 at day 1, 4 at day 3 and 1 at day 7. Morbidity rate was 4.3%. After a mean follow-up of 28.5 months none recurrences were observed., Conclusions: Our study confirmed the feasibility of laparoscopic repair in terms of postoperative morbidity and recurrence rate. Thus laparoscopic primary ventral hernia repair should be considered an effective alternative to open techniques.

The anastomotic leakage is one of the most serious complications following colorectal surgery. The incidence rate is between 3% and 21% considering the different experiences, pathology and surgical techniques. Our aim is to verify the role of radiological study in 45 patients with clinical and subclinical colorectal anastomotic leakage total anastomoses = 252). In 31 patients at risk, the operation was concluded with a loop ileostomy. The radiological study gastrografin enema was performed in all patients (26 symptomatic and 19 asymptomatic patients with loop ileostomy). The dehiscence incidence resulted 5.5%: 14 of 252 patients. In our experience the radiological study of selected colorectal anastomoses allowed to show the site and the flow of the leakage and to plan the proper management. In asymptomatic patients the study allowed to programme a specific follow up in patients with higher risk of postinflammatory stenosis or perhaps neoplastic relapse.

Three cases of histologically proven primary non-ampullary adenocarcinoma of the duodenum, observed in our Department from 2001 to 2004, are described. The cases were treated by pancreaticoduodenectomy, duodenal resection and transduodenal excision, respectively. The rarity of this pathology is documented by few retrospective studies and justifies discussion about the main prognostic factors and the best therapeutic approach. We analyze diagnostic, therapeutic and prognostic factors after a revision of literature.

The application of laparoscopic principles to ventral or incisional hernia repair has recently been shown to be a safe and effective alternative to open procedures. In this study we analyzed our recent experience with laparoscopic incisional-ventral hernia repair. The outcomes of 75 consecutive patients (January 2002 to July 2006) who underwent laparoscopic repair for incisional-ventral hernia were reviewed. Patient's demographics, hernia parameters, and intraoperative and postoperative data were collected. Of the 75 patients, 44 were females and 31 males. Mean age was 59.1 yrs (range 29-80 yrs). Mean BMI was 25.9 (range 19.4-36.7). Twenty-one patients had primary ventral hernias while 54 patients had an incisional hernia. Fifty-three patients had a single defect and 22 patients multiple defects. In 45 cases the incisional hernia was a primary hernia; in 4 cases it was a first recurrence; in 2 cases a 2nd recurrence; and in 3 cases a 3rd recurrence. The mean defect size was 52,7 cm2 (range 4-432). Laparoscopic hernia repair was successfully performed in 71 cases (94.7%). The mean mesh size was 211 cm2 (range 63-694). Mean operating time was 101 min (range 50-220 min). The mean hospital stay was 4.7 days. The postoperative morbidity rate was 14%. After a mean follow-up of 24.6 months (range 7-56) the recurrence rate was 7% (5/71). Laparoscopic repair of incisional-ventral hernias seems to be safe and effective. Medium-term outcomes were promising with a relatively low rate of conversion to open surgery, a low complication rate and a low risk of recurrence.

Acute right lower abdominal pain is often clinically difficult to diagnose. The diagnosis, especially in young patients, is frequently oriented to appendicular disease. Surgical exploration only confirms diagnosis or surprises the surgeon, revealing an unexpected right colon diverticulitis. This emergency condition challenges the surgeon with the dilemma about the best therapeutic choice: conservative or radical treatment? The elective localization of diverticulitis to the right colon is very rare (6.6-14%). The authors report a case of covered perforation of a solitary cecal diverticulum.

The diagnosis of liver adenoma, which etiopathogenesis most often involves a prolonged assumption of estrogen (90% of adenomas occurs in women after more than 5 years of estrogen therapy), always imposes a surgical resection. The reason depend from neoplasia characteristics like the malignant evolution (4%) and the high risk of abdominal/intratumoral bleeding (30-50%), that increases during pregnancy and postpartum period. Regression of lesion after discontinuation of hormone therapy is rare and does not remove the degeneration and/or haemorrhagic risk. Liver resection should be performed with appropriate selective endovascular embolization, considering that an inept emergency surgery may impose a greater risk ot the liver, exposing the patient to major risk of morbidity and mortality. The correct timing from embolization to elective surgery is not yet standardized in the literature. The surgeon's personal experience and mainly a careful patient follow-up suggest the timing of surgery after embolization. The authors relate their own experience about the therapeutic strategy and surgical timing in a case of bleeding liver adenoma.

As life expectancy continue to increase, many elderly patients may be considered for pancreaticoduodenal resection. The purpose of the study was to review our experience with pancreatic resection for periampullary evaluating immediate and long-term results in patients aged 75 or older.

Radiofrequency (RF) was used to ablate 42 colorectal liver metastases in 20 patients (10 males and 10 females) in a four years period. Median age was 62.2 years, 36 lesions (75%) had 3 cm diameter or less. An open surgical approach was adopted in 13 patients, whereas a percutaneous one in 14. On 27 surgical sessions, RFA was used in 49 procedures for a total of 81 needle applications. Morbidity was 6.0% (3 cases), one patient died on third po day for myocardial infarction. No differences in terms of complete ablation rate was observed in the two approach's groups. Overall survival was 65% with a median follow-up of 18.5 months.

Pancreatic carcinoma remains a letal disease with an overall 5-year survival of less than 5%. Recent reports of increases in actuarial survival after resection have determined some optimism. Our objective was to identify the actual 5-year survival rate of patients with pancreatic carcinoma who underwent a resection with curative intent, analyzing those factors associated with a more favorable prognosis.

Pancreaticoduodenectomy has a primary role in the treatment of patients with periampullary carcinoma. Several series have reported encouraging operative mortality and survival after resection. Controversies exist regarding the impact of preoperative biliary drainage on immediate and long-term results.

Radiofrequency thermal ablation (RFA) of liver tumor is done by percutaneous, laparoscopic and open surgical approach. Selection criteria for percutaneous or open surgical ablation of 54 hepatic lesions are here evaluated in 30 consecutive patients. Open surgical approach was performed in 9 cases only, 5 of them due to concomitant treatment of associated diseases. Number and size of the lesions did not interfere with surgical approach. Postoperative CT control showed no differences in terms of complete ablation of the tumor in between the two groups of patients. Percutaneous approach of RFA is gone to be in the future the modality of choice in these patients.

Aims and Background: Surgical resection offers the only potential cure for pancreatic carcinoma. Although the overall prognosis remains a dismal, several recent series have reported an encouraging increase in 5-year survival after resection, exceeding 20%. As the reasons for this improvement are not clearly understood, numerous clinico-pathological parameters (demographic, intraoperative and histopathologic factors) have been investigated to evaluate their role in predicting long term survival. In this single-institution study, immediate and long-term outcome after pancreatic resection in patients with pancreatic adenocarcinoma was retrospectively evaluated, focusing attention on the possible impact of different clinico-pathologic factors on long-term survival., Methods: Sixty-six patients with a confirmed histologic diagnosis of adenocarcinoma of the pancreas, treated by pancreatic resection at the Department of Surgery of the Catholic University of Rome in the years 1988-1997, were retrospectively analyzed. Morbidity and survival data were reviewed and potential prognostic factors were compared statistically by univariate analysis., Results: There was no postoperative mortality. Twenty-five patients (38%) developed major operative complications. Pancreatic fistula was the most common complication, and occurred in 7 patients (11%). The actuarial overall and disease-specific survival for all 66 patients were respectively 58% and 59% at 1 year, 27% and 31% at 3 years, and 13% and 20% at 5 years, with a median survival time of 13.4 months. Nodal status was the only single factor significantly affecting survival by univariate analysis. The 3-and 5-year survival rates were respectively 35% and 19% for node-negative patients and 7% and 0% for node-positive patients (P = .04). A positive correlation with improved survival, even if not of statistical significance, was shown for other pathologic or intraoperative factors. Among the former, 5-year survival rates were better for patients with negative resection margins as compared to patients with positive margins (12% vs 7%, P = ns). Among the latter, a better actuarial 5-year survival rate was shown for patients with shorter operative time (< 4 hours, 21% survival vs > 4 hours 5%, P = ns) and for patients that received fewer transfusions (0-2 blood units, 14% survival vs 3 or more blood units, 0%; P = ns). Age, gender, tumor diameter and tumor grading showed no influence on survival in this series., Conclusions: Our series confirmed that nodal status is the strongest independent predictor of survival. Limited intraoperative transfusion, reduced operative time and clear margins could also yeald a prognostic significance, and require further confirmation in larger series.

Purpose: The aim of this study was to evaluate, in a group of patients suffering of colo-rectal cancer, the influence on local recurrence of some clinical and anatomo-pathological variables., Methods: The study was limited to 833 patients who underwent potentially curative resection and have been followed for at least two years. All patients were evaluated every six months for the first three years and yearly thereafter by means of clinical, laboratory, endoscopic and radiological investigations. Recurrence was observed in 78 patients (9.4%); 19 of these had evidence of distal failure simultaneously (2.2%). The incidence was 2.4% and 17.7% in the carcinoma of the colon and rectum respectively. Median time of recurrence was 16 +/- 11 months; 75% presents within 23 months from operation. Chi-square test was used to relate incidence of recurrence to clinical and anatomo-pathological factors and then a multivariate logistic regression analysis was used to evaluate the most significant variables., Results: Univariate analysis reveals a significant relationship between recurrence and age under 50 years (p = 0.01), presence of preoperative complication (p = 0.01), stage (p = 0.01), site (p = 0.000) of primary tumor and lymph-nodal involvement (p = 0.0002). No statistically significant difference was found between recurrence and tumor wall infiltration, number of lymph nodes involved, grading and morphology of primary tumor. Multivariate logistic regression analysis confirmed these results except for preoperative complication (p = 0.9)., Conclusions: Authors believe that selection of patients to undergo adjuvant therapies is improved by identification of high-risk patients.

Aim of this phase I-II study was to evaluate the efficacy of preoperative concomitant radiochemotherapy in resectable high risk (TNM stage: II and III) rectal tumors, 64 patients entered the study: 37 had low rectal cancer, 27 mid-rectal cancer. 50 patients were clinically staged as stage III (Dukes C) and 14 as stage II (Dukes B). Treatment protocol included bolus mitomycin C at the dose of 10 mg/m2 on day 1 and 5FU continuous infusion at the daily dose of 1000 mg/m2 on day 1, 2, 3, 4. Concomitant external radiotherapy up to a dose of 3780 cGy was delivered at the daily dose of 180 cGy. Surgery was performed 4 to 5 weeks after radiation therapy (RT). Before surgery all patients were clinically restaged to evaluate the response to concomitant radiochemotherapy. Treatment compliance was 97%. Toxicity was 27% prevalently shown as bone marrow depletion and radiodermatitis. In 37 patients (61%) there was 50% reduction (partial response) of neoplastic volume. In 5 patients (8%) no neoplastic cells were evidenced in the surgical specimen on histology (complete response). The distance between the lower margin of the tumor and the internal anal orifice increased in 72% of cases. Postoperative morbidity was 28%. The incidence of anastomotic dehiscences was 8.7% over 46 anterior resections. Postoperative mortality was nil. Definitive staging evidenced 24 patients (39%) stage I or with no evidence of tumor. The incidence of local recurrence was 5% and that of distant metastasis 8%.

The authors' experience with local excision (LE) and adjuvant radiotherapy in the treatment of selected cases of rectal cancer, is reported. 41 patients with distal rectal cancer underwent elective LE for cure. Selection criteria were: the site of tumor in the lower rectum, exophytic growth, maximum diameter equal to or lower than 4 cm, tumor "freely" mobile on the rectal wall, clinical staging T1-2 N0M0, histological grading G1-2. Patients shown to be T2 on definitive histology underwent adjuvant radiotherapy to the site of tumor and to pelvic lymph nodes. LE was performed via transanal route under general anesthesia. Operative mortality was 0% and morbidity 7.3%. In 37 cases (90%) surgery was considered radical and curative. The incidence of local recurrence was 5.4%, overall evidence of disease 8.1%, cancer-specific mortality 5.4% and 5-year actuarial survival 90%. The combination with radiotherapy has achieved similar results in T1 (22 cases) and T2 (15 cases) tumors. It is concluded that LE combined with radiotherapy in T2 tumors in selected cases represent a valid therapeutic alternative to more demolitive surgery.

The evolution of the surgical management of rectal cancer is briefly reviewed. Factors which influence the choice of the surgical procedure relatively to the tumor characteristics, are examined. The role played by preoperative staging as the basis of a correct therapeutic approach is underlined. Most common surgical procedures in rectal cancer treatment are reported, and emphasis is put on aspects of particular interest for radiodiagnosticians and radiotherapists.

The treatment of anterior mediastinal tumours is often subordinated to histological diagnosis. Sometimes topographic, radiographic and clinical criteria are sufficient to indicate surgical therapy. From January 1988 to June 1992, 31 patients (40.7%) underwent immediate surgery, while 47 patients (59.3%) underwent fine needle aspiration and Trucut biopsy under ultrasonographic or computed tomographic guidance. Thirteen of these patients had also an anterior mediastinotomy according to McNeill-Chamberlain technique. In 36 patients it was possible to verify accuracy of diagnostic procedures comparing these specimens with surgical histological reports. Only 3 patients had minimal complications. No patients undergone anterior mediastinotomy had morbidity or mortality. Our reports show that transthoracic fine needle aspiration and Trucut biopsy have a diagnostic accuracy of 72% and 83% respectively in identifying malignant from benign lesions. These procedures are not adequate to detail diagnosis for tumours with pleomorphic pathologic characteristics (diagnostic accuracy of 39% and 75% respectively). This disagreement is due to false-positive results (one for fine needle aspiration and four for tru-cut biopsies), this discordance occurred in lymphomas and thymomas groups. Such correct diagnosis is very important either for frequency of these tumours either for different therapeutic approach: chemo-radiotherapy in lymphomas and surgery in thymomas.

An univariate analysis of pathologic data of 987 patients with primary colorectal carcinoma treated over a period of 22 years was performed. Six variables such as tumor site, histologic type, depth of invasion, nodal involvement, distant metastases, histologic grade and tumor stage were tested for their prognostic value. 5-year survival rate was investigated. Patients with tumors in the left colon and rectum have shown a better prognosis than patients with tumors in the right colon (53-51% vs. 38% p = 0.0007). As regard histologic type non significant differences between mucinous and non-mucinous carcinoma was observed (44% vs 48% respectively p = 0.4). The depth of tumor invasion was an important prognostic factor; according to tumor infiltration patients can be divided in four groups (T1, T2, T3, T4) with 5-year survival rates of 80%, 74%, 39% and 16% respectively (p = 0.0000). Highly significant decrements in survival occurred when lymph node metastases were demonstrable (20% vs. 67% p = 0.0000). Prognosis was still strongly related to histologic grade, with significant difference in survival rates between G1 and G2-G3 tumors (71% vs. 48%-42% p = 0.0000). Finally prognosis was closely related to the stage of spread at the time of diagnosis.

The authors report their experience with Hartmann procedure. 28 patients were treated: 21 males and 7 females. The mean age was 58 years. Perforative diverticulitis was the commonest indication (14 patients), followed by carcinoma (11 patients). Miscellaneous causes accounted for 3 patients. This procedure was primarily performed as an emergency operation (71%). One patient died post-operatively (3.5%); post-operative morbidity was 10.7%. A second operation was not planned if the first operation had been performed for palliation of metastatic or locally advanced cancer (7 patients). Restoration of colonic continuity was achieved successfully in 14 patients with no mortality and morbidity. According to their experience, authors believe Hartmann procedure to be the most suitable operation facing a left colon emergency. It is usually easy to perform and well tolerated by poor risk patients.

Mebendazole (50-60 mg/kg/day in 7-8 divided doses after fatty rich meals for at least 6 months) was given to 44 patients with cystic hydatid disease of the liver and other organs, about 1/3 having suffered from recurrences, even multiple, before beginning the pharmacological treatment. Fifteen patients underwent operation after a course of mebendazole, and macroscopic and histological degeneration of hydatid cysts was always documented; sixteen subjects were not operated due to their severe general and/or local conditions but ultrasound, radiologic (CT) and clinical evidence of cyst regression was obtained, and was closely comparable to that in the aforementioned group. Some of the patients (13) began the treatment only after conservative surgery. The mean real follow-up available at the moment is for 40 subjects because 2 patients did not show adequate compliance for the drug and in 2 additional cases it was withdrawn because of an increase in serum transaminases. The rate of recurrence was 7.5% and occurred in high-risk patients (multiple, bone, lung locations) who had, however, an additional and longer course of mebendazole with good results. The detachment of membranes and the increase of internal echoes, observed by means of ultrasonography, which was successfully applied to liver and soft tissue sites as well as the decrease in blood eosinophils when elevated before therapy, were observed to be the most sensitive indicators of early success in the medical treatment for hydatid disease, as far as the viability of parasite cysts was concerned.

Fourteen cases of hemobilia of traumatic (six), vascular (six) or neoplastic (two) origin were reviewed. Eleven patients obtained correct diagnosis only be integration of at least two diagnostic procedures out of Ultrasonography, Computed Tomography, arteriography and cholangiography. Although US and CT are extremely useful as screening procedures, correct diagnosis should be only possible by integration of more diagnostic technics. Arterial embolization represents a successful alternative to surgical intervention; moreover US may also be helpful for follow-up of treated patients.
