Laparoscopic pancreatic surgery: indications, techniques and preliminary results.

BACKGROUND/AIMS: The purpose of this study was to evaluate feasibility, effectiveness and reproducibility of laparoscopy in the diagnosis and management of pancreatic diseases. METHODOLOGY: At the Second Department of Surgery of the "Regina Elena" Institute for Cancer Research, between June 1995 and June 1997, possibilities of the laparoscopy in diagnosis and staging of pancreatic malignancies were studied. Twenty-four consecutive cases of pancreatic adenocarcinoma were observed: 10 patients were pre-operatively considered unresectable and 14 cases were submitted to a laparoscopic study. Moreover, in the period from January 1996 to June 1997, a study on the therapeutical potentialities of laparoscopy was performed, attempting 5 pure or assisted laparoscopic pancreatic resections. RESULTS: Three cases (21.4%) out of the 14 evaluated were found to be metastatic (liver and peritoneum); 11 patients were successfully resected with an open standard procedure. Laparoscopy allowed a correct staging in all cases, even in the 21.4% of ultrasonography (US), TC and angiographic false negatives. The 5 operative procedures consisted of one resection of a cystadenoma, one resection of a head cyst, one Wirsung lithotomy with pancreaticojejunostomy for lithiasic chronic pancreatitis, and two body-tail splenopancreatectomies (1 cystadenoma and 1 adenocarcinoma). Satisfactory early results were obtained in all these cases. CONCLUSIONS: Laparoscopic diagnosis and staging of pancreatic cancer is a valuable method which allows a very high accuracy. Pancreatic resections, even if feasible, are still to be considered an experimental procedure.

Diagnostic and surgical features of Klatskin tumors.

AIM OF STUDY: Klatskin tumors are rare and their prognosis is poor. Long term survival can be expected only after a surgical resection, the treatment of choice. The aim of this study is to report our single centre experience and, by literature analysis, to define the role of surgery in the treatment of hilar cholangiocarcinoma. MATERIALS AND METHODS: Between 1990 and 1998, 27 patients affected by Klatskin's tumor were observed. Eight women and seven men (mean age 59 years) underwent surgical resection. Thirteen patients (86%) had curative resection (7 hilar resection (HR), 4 HR combined with partial hepatectomy (PH) and 2 HR + PH with portal vein resection). Two patients (13%) had palliative biliary resection and surgical drainage. RESULTS: One in-hospital death was recorded after a right hepatectomy with portal vein resection (6.6%). Postoperative morbidity rate was 40%. Patients were regularly followed up to date or to death. Ten patients died and 5 survived. The 1-, 2- and 3-year survival rate after curative resection was 84%, 54% and 34%. The median survival was 28.5 months. Lymph node involvement did not show a statistically significant difference on median survival between the positive group and the negative group (26.2 vs 29.8 months), nor did perineural invasion, because of the small number of patients. The 1-, 2-, 3- and 5-year survival rate after isolated hilar resection was 100%, 57.1%, 28.6% and 0. Four out of 6 patients who underwent hilar resection combined with partial hepatectomy are still alive 1, 23, 29, 38 months after resection. Hepatectomy increased mortality (16% vs 0). Palliative biliary resection and surgical drainage were successfully performed in 2 patients with satisfactory results. CONCLUSION: Aggressive surgical treatment of Klatskin tumors can improve patients' survival. Careful preoperative management has to be carried out by a multidisciplinary approach including surgeons, gastroenterologists, radiologists and pathologists. Hepatic resection involving the caudate lobe is often performed in order to obtain microscopic tumor-free margins and curative resection (R0). Biliary drainage and treatment of cholangitis is mandatory before surgery in order to improve surgical outcome. Surgical treatment is characterized by high technical difficulties and better results can be achieved by hepatobiliary surgical teams.

[Carcinoma of the hypopharynx: reconstruction of the pharyngo-esophageal tract after circular pharyngectomy by the transplantation of a U-shaped jejunal loop to the neck].

Reconstruction of the oro- and hypopharynx has specific difficulties duo to their wide diameters. Thirteen patients underwent reconstruction with a free U-shaped jejunal transplant, after circular pharyngo-laryngectomy for hypopharyngeal cancer invading the oropharynx. This transplant included a side-to-side anastomosis between the two limbs of the jejunal loop and allowed reconstruction of the upper digestive tract after wide carcinologic resection of the pharynx. The U-shaped jejunal transplant facilitated the upper anastomosis, especially the upper part where the resection involved the oropharynx. It formed a reservoir behind the tongue and avoided nasal reflux. Best indication are large resections involving the oropharynx.

[Liver metastasis of breast carcinoma. Results of surgical resection. Analysis of 15 operated cases].

AIM OF THE STUDY: The aim of the study was to define the efficacy of liver resection for metastases from operated breast cancer by means of analysis of the results of a single institution compared to the literature data. MATERIALS AND METHODS: Over the period from 1990 to 1998, 15 patients with liver metastases from operated breast cancer were submitted to surgical resection. Thirteen patients were operated on for single metastases and two for multiple liver metastases. In the first group, a simple metastasectomy or wedge resection was sufficient, while in the second a bisegmentectomy and a right hepatectomy, respectively, were performed. Nine patients were subsequently submitted to adjuvant chemotherapy, two to chemo- and hormonotherapy, and two to hormonotherapy alone, while two other patients received no systemic treatment. RESULTS: No major complications or postoperative mortality were observed. Median survival was 44 months. The actuarial 5-year survival rate was 38.3%. Eight patients are still alive, and 7 patients have died as a result of their liver and systemic metastases. CONCLUSIONS: Hepatic metastasis from breast cancer is a good indication for surgical resection. Resection is capable of providing curative treatment and better results in terms of quality of life and survival rates, as compared to chemotherapy and hormonotherapy, especially in patients operated on for primary tumours more than three years earlier.

[Experience of 10 years with the surgical treatment of lung cancer in elderly patients].

The surgical treatment of lung cancer in elderly patients is correlated with a lot of complications that in most cases are cardiopulmonary type; for this reason, in past times these patients were left out of the surgical treatment. Today, the progress of surgical, diagnostic and anesthetic techniques permit to execute pulmonary resections in patients older than 70 years too. The aim of this study is to evaluate postoperative complications and long-term and long-term survival in patients under and over the age 70. Between January 1990 and June 2000 we have assessed 172 patients with lung neoplasm. We have divided patients in two groups: those younger than 70 years of age (group 1, n = 119) and those older than 70 years of age (group 2, n = 53). Postoperative mortality for group 2 was 7.5% and for group 5.1%. The overall postoperative complication rate for group 2 was 30.2% and for group 1 10.9%. Within group 1 main complications have been of surgical type (61.5%) while in group 2 medical type (cardiopulmonary), with higher frequency in patients ASA 3 or ASA 4. The mortality at 12 months for non-neoplastic causes was 10.2% for group 2 and 2.5% for group 1. On the contrary, the mortality at 12 months for neoplastic causes was 8.2% for group 2 and 6.7% for group 1. We haven't noticed an important correlation between the extension of the resection and the recurrence of disease. The survival at 3 years was 46.5% for group 1 and 41% for group 2 and associated with neoplastic causes.

Aspirin does not interact with ACE inhibitors when both are given early after acute myocardial infarction: results of the GISSI-3 Trial.

Aspirin (ASA) and angiotensin-converting enzyme inhibitor (ACEi) therapy reduce mortality when administered early after the onset of myocardial infarction. ASA can antagonize some effects of ACEi therapy by inhibiting the synthesis of vasodilating prostaglandins; however, the evidence for this effect from large controlled trials is contradictory. The authors analyzed a database of 18,895 patients of the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardio-3 (GISSI-3) Trial in which patients were allocated either to receive lisinopril or not to receive lisinopril within 24 hours of the onset of symptoms of myocardial infarction. The aim of the study was to verify the possible negative interaction between ASA and the ACEi lisinopril in the postacute phase of acute myocardial infarction. Of 18,895 analyzable patients, 15,841 received ASA at entry. Overall lisinopril reduced 42-day mortality from 7.1% to 6.3%. In patients receiving ASA, mortality was reduced by lisinopril from 6.0% to 5.4%, and from 13.0% to 10.8% in patients not receiving ASA. The difference in proportional reductions of mortality corresponds to the fact that a more marked lisinopril effect is seen in patients at higher baseline risk across all study subgroups, one of which coincides with the no-ASA group. The analysis of the inhospital incidence of major clinical events did not reveal a potentially negative interaction between ASA and lisinopril. The same findings were obtained from the analysis of reinfarction at 42 days. The interaction between ASA and lisinopril was also tested by multivariate analysis adjusted for confounding variables at entry, and the interaction tests were not statistically significant. Serum creatinine levels at 42 days were significantly higher in lisinopril group than in the control group. Systolic and diastolic blood pressures in lisinopril group were significantly lower than controls at 42 days. The effect of lisinopril on creatinine and blood pressure did not differ between the ASA and no-ASA groups. ASA does not decrease the mortality benefit of early lisinopril after myocardial infarction, nor does it increase the risk of major adverse events. Lisinopril is safe and effective when given early after the onset of myocardial infarction, regardless of a concomitant administration of ASA started early and continued over a 6-week period.

[The modified "hanging maneuver" during orthotopic liver transplantation using a technique for conserving the inferior vena cava].

We describe a modification of Belghiti's "liver hanging maneuver" applied to the last phase of hepatectomy during OLT with IVC preservation. The proposed maneuver provides a better exposition of the suprahepatic veins allowing an ortogonal clamping of the suprahepatic confluence and avoiding caval clamping. It allows, moreover, an increase of venous surface available for the anastomosis that results wider and easier to perform. This provides a large outflow anastomotic cloaca and prevents outflow problems of the graft.

[Acute liver toxicity of antiretroviral therapy (HAART) after liver transplantation in a patient with HIV-HCV coinfection and associated hepatocarcinoma (HCC)].

OLT in HIV infected patients still remains a challenging option requiring a careful monitoring of patients for HCV reinfection, drug interactions and antiretroviral toxicity. Severe adverse events due to HAART have been already reported for post exposure prophylaxis in HIV infected patients. Here we report a case of liver graft toxicity related to HAART in a HIV-HCV co-infected patient (46 yrs-male) with associated a small HCC transplanted with a marginal liver graft. The patient had pre-OLT plasma HIV 1-RNA levels undetectable and CD4+ T-cell count of > 200 cells/microL for 6 months. At day 2 a severe graft dysfunction was observed (AST 1570 U/L, ALT 2180 U/L, BIL tot 8.3 mg/dL, BIL Dir 6.6 mg/dL and PT 35%--INR 2.5). Doppler scan showed hepatic artery always patient. Later the postoperative in-hospital course was complicated by tense ascites and severe cholestasis. Serum bilirubin reached 42 mg/dL in day 12. Hypertransaminasemia ended at day 15 while cholestasis ended after 46 days. Tacrolimus was reintroduced at day 7. A liver biopsy 10 after OLT showed severe intrahepatic cholestasis, centrolobular necrosis and macrovesicular steatosis (30%). The patient was discharged 48 days after OLT with good liver function. After seven months HIV-RNA is still undetectable and HAART has not been restarted. We believe that the early complications we observed may be attributed to a sudden increase in plasma concentration of antiretroviral drugs secondary to drug redistribution from peripheral tissues and hepatic clearance deficiency after OLT. Although a pre-OLT withdrawal of HAART seems unjustified a delayed re-introduction of HAART or the use of less hepatotoxic drugs may be advisable.

[Isolated resection of the caudate lobe in metastasis of colorectal cancer].

The presence of metastatic lesions confined to the caudate lobe (CL or segment I) is quite a rare event. Even more rare is the decision to perform an isolate CL resection. Segmental resection in the liver is justified by the evidence that primary and secondary lesions, in early stage, are confined to the originating segment, and therefore a segmentectomy can be considered for the CL as well. Anatomy of the CL was deeply studied through the years since the surgical approach to this liver segment requires a detailed knowledge of its surgical anatomy and only after 1985 the surgical technique for CL isolate resection was established. We report our experience with 1 case of isolate colo-rectal metastasis confined to the caudate lobe and describe the surgical technique employed.

[Hypersensitivity vasculitis after thrombolytic therapy with APSAC (anisoylated plasminogen streptokinase activator complex). Presentation of a clinical case and review of the literature].

We describe a rare case of hypersensitivity vasculitis associated with APSAC administration in a 54-year-old man. Fifteen days after receiving thrombolytic therapy (APSAC 30 U) for acute myocardial infarction, the patient was admitted to our department for myalgia, livedo reticularis and erythema of the legs with an ulcerative necrotic lesion of the fifth toe of the right foot. The presence of circulating immune complexes at high titer supported the diagnosis of hypersensitivity vasculitis.

Gastric cancer cell DNA content correlates with early and late results after gastrectomy.

The DNA content of 59 adenocarcinomas of the stomach in patients who had undergone subtotal or total gastrectomy more than 5 years before was measured. The DNA measurements were done by flow cytometry performed on Propidium Iodide--stained cells disaggregated from paraffin-embedded tissues. Fifty-nine evaluable good quality histograms of DNA ploidy patterns were obtained. The Proliferative Index (PI) was determined in 35 cases. The remaining 24 cases didn't show a reliable reading histograms. Of the 59 tumors, 33 (56%) were diploid and 26 (44%) were aneuploid; 19 showed a high PI (> or = 3.8%) and 16 a lower one. A statistically significant difference was found between the two groups (diploid/aneuploid and low/high PI) compared to the prognostic values known as T, N and Stage. 65% of the T3-T4 cancers, 54% of the N1-N2 lesions and 58% of the stage III and IV were found to be aneuploid. 73.7% of the 19 tumors presenting high PI, showed an aneuploid pattern. A high PI was found in 71.4% of the T3-T4 tumors. 77.4% of patients of the diploid group (any stage) survived at 5 years against 36% of those presenting aneuploid patterns. Patients with PI > or = 3.8% showed a 42.1% 5-year survival rate. A 94.4% 5-year survival rate of diploid and early stage cancers was documented against a 33.5% of aneuploid and advanced stage cancers.
