RESUMO
BACKGROUND: Although laparoscopic splenectomy (LS) has become the standard approach for most splenectomy cases, some areas still remain controversial. To date, the indications that preclude laparoscopic splenectomy are not clearly defined. In view of this, the European Association for Endoscopic Surgery (EAES) has developed clinical practice guidelines for LS. METHODS: An international expert panel was invited to appraise the current literature and to develop evidence-based recommendations. A consensus development conference using a nominal group process convened in May 2007. Its recommendations were presented at the annual EAES congress in Athens, Greece, on 5 July 2007 for discussion and further input. After a further Delphi process between the experts, the final recommendations were agreed upon. RESULTS: Laparoscopic splenectomy is indicated for most benign and malignant hematologic diseases independently of the patient's age and body weight. Preoperative investigation is recommended for obtaining information on spleen size and volume as well as the presence of accessory splenic tissue. Preoperative vaccination against meningococcal, pneumococcal, and Haemophilus influenzae type B infections is recommended in elective cases. Perioperative anticoagulant prophylaxis with subcutaneous heparin should be administered to all patients and prolonged anticoagulant prophylaxis to high-risk patients. The choice of approach (supine [anterior], semilateral or lateral) is left to the surgeon's preference and concomitant conditions. In cases of massive splenomegaly, the hand-assisted technique should be considered to avoid conversion to open surgery and to reduce complication rates. The expert panel still considered portal hypertension and major medical comorbidities as contraindications to LS. CONCLUSION: Despite a lack of level 1 evidence, LS is a safe and advantageous procedure in experienced hands that has displaced open surgery for almost all indications. To support the clinical evidence, further randomized controlled trials on different issues are mandatory.

BACKGROUND: The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was developed to provide at the national level an informative tool useful for performing multicenter studies in the field of spleen laparoscopic surgery. In this first study analyzing the IRLSS data, a cohort of patients with hematologic diseases was retrospectively investigated for potential predictive parameters that could affect the outcome of laparoscopic splenectomy. METHODS: A total of 309 patients who underwent laparoscopic splenectomy for hematologic diseases in 17 Italian centers (between February 1, 1993, and September 30, 2004) were entered in the IRLSS. Their records were analyzed retrospectively by the Student's t-test, chi-square, and logistic regression. RESULTS: The mean operative time was 141 min (range, 30-420 min). Conversion was necessary in 21 cases (7%), and approximately 1 accessory spleen in 25 patients (9%) was found. The mean spleen weight was 1191 g (range, 85-4,500 g). Perioperative death occurred in two cases (0.6%). No complications were experienced by 253 patients (81.9%), who had a mean hospital stay of 5.4 days (range, 2-30 days). Overall morbidity occurred in 56 patients (18.1%), mainly associated with transient fever (n = 22), pleural effusion (n = 13), and actual or suspected hemorrhage (n = 12), requiring a reintervention for 7 patients. Multivariate analysis found that body mass index (p = 0.024) and clinical indication (p = 0.004) were independent predictors for surgical conversion. The clinical indication was almost significant as an independent predictor for the occurrence of postoperative complication (p = 0.05). CONCLUSIONS: This first study analyzing the IRLSS data shows that laparoscopic splenectomy may represent the gold standard treatment for hematologic diseases with normal-size spleen. The low morbidity and mortality rate suggests that laparoscopic splenectomy can be successfully proposed also for splenomegaly in hematologic malignancies.

BACKGROUND: This study aims to evaluate the completeness of full thickness disc resection in the treatment of deep endometriotic bowel lesions. METHODS: This study comprised 16 women with bowel endometriotic lesions requiring segmental resection. For the purpose of the study, before intestinal resection, nodulectomy was performed. The presence of endometriotic infiltration in direct continuity with the removed nodule and the presence of fibrosis in the area surrounding the nodule were histologically evaluated. RESULTS: In seven out of 16 cases (43.8%; 95% CI, 19.8-70.1), endometriosis was found in the bowel wall adjacent to the site of nodulectomy; the infiltration was visible in the muscular layer in all cases. In cases of incomplete nodulectomy, the muscular layer of the bowel segment surrounding the endometriotic nodule contained limited or no fibrosis. CONCLUSIONS: Full thickness disc resection is not complete in > or =40% of women with bowel endometriosis. Our finding that fibrosis in the muscular layer, the main landmark during surgical resection, does not always surround bowel endometriotic lesions might explain why incomplete resection may occur.

A 40-year-old woman with a 3 cm sigmoid polyp lesion who underwent a laparoscopic colon resection after intraoperative localisation of the lesion using laparoscopic ultrasonography coupled with colour power Doppler is described. She has successful intraoperative detection of the polyp followed by radical laparoscopic removal of the lesion. The advantage of using laparoscopic high resolution ultrasonography coupled with colour power Doppler to locate colonic polyp lesions during a laparoscopic colon resection is that intraoperative colonoscopy can be avoided. Intraoperative ultrasonography of the colon can accurately localise colonic polyp lesions that are not detectable during laparoscopy and represents a quick and effective alternative to other imaging techniques.

Cluster headache (CH) has traditionally been considered a sporadic disease. Recently, an Italian study pointed out a risk of developing CH in the affected patients' firstdegree relatives that was increased 39-fold compared with the general population. The aims of this study were to investigate any possible differences in mean age at onset, clinical features and lifestyle between familial and non-familial CH cases. Among all CH patients referred to the Parma Headache Centre (n=691), we considered those who reported at least a first-degree relative with a probable diagnosis of CH in their family histories (n=30). CH diagnosis in the relatives was confirmed for 19 of the 30 patients. Each one of the 19 "familial cases" was matched by sex and age at the first visit (within 2 years) to two CH patients who did not report any family history for CH. The male:female ratio was 1.4:1 in the familial cases. Mean age at onset was significantly lower in women with familial CH than in those with non-familial CH. The study did not show any significant differences in symptoms between the two CH groups, such as pain location, accompanying symptoms, duration and frequency of attacks, and active periods. Our study seems to suggest that genetic factors play a role in the female gender, affecting age at onset of headache without modifying the clinical features.

BACKGROUND: We reviewed retrospectively the records of all patients who underwent laparoscopic splenectomy (LS) at our institution for a wide range of hematological disorders. We compared our experience to those reported in the literature and analyzed various aspects of the treatment that are still under discussion and in need of confirmation, such as the treatment of malignant blood diseases, the indication in case of splenomegaly, and the adequacy of the detection of accessory spleens. METHODS: Between June 1997 and June 2001, we performed 43 LS. The patients were classified into three groups according to clinical diagnosis: idiopathic thrombocytopenic purpura (ITP) (n = 23), hemolytic anemia (HA) (n = 5), and hematological malignancy (HM) (n = 15). Statistical analyses were done to compare the three groups. RESULTS: LS was completed in 41 patients, with a conversion rate of 5%. Splenomegaly was present in 37% of all patients (73% of HM). Mean operative time was 128 min. The incidence of accessory spleens was 20%. A concomitant laparoscopic procedure was done in three cases (cholecystectomy). Postoperative complications occurred in eight patients (18%). Duration of surgery, length of hospital stay, transfusions rate, and some demographics features, such as age and spleen weight and length, were significantly different in each group. No deaths were attributed to the procedure. CONCLUSIONS: The statistical analysis of our series shows that, the laparoscopic approach reliable even in the management of malignant and nonmalignant blood diseases.

BACKGROUND: We analyzed, using a theoretical model, the modality of recurrence after a simple cruroplasty for large hiatal hernias, and on the basis of physical and geometrical principles, we conceived a new shaped mesh for a "tension-free" repair. METHODS: We performed a physical and geometrical analysis of the hiatal region on a theoretical model. We also performed an anatomic study on 20 fresh cadavers to verify the reproducibility of the theoretical model and to study the most suitable shape for mesh and its adaptability to the hiatal region. Between September 2000 and October 2001, eight patients received laparoscopic reparation of large (type II or III) hiatal hernias by means of a composite "A"-shaped polytetrafluoroethylene (PTFE)-polypropylene mesh. There were two men and six women; mean age was 65 years (range, 35-78 years). Concomitant esophagitis was found in five patients and impaired esophageal peristalsis in two patients. A total or a partial fundoplication was associated in these cases. RESULTS: The physical and geometrical analysis of the hiatal region explained the reasons for the recurrence after hiatoplasty. The anatomical study on fresh cadavers resulted in a mesh tailored in an "A" shape and permitted to verify the adaptability of such a shaped mesh composed of two layers, polypropylene and PTFE. In the clinical series no conversions occurred; the mortality rate was null. Persistent dysphagia was present in two patients and disappeared after 3 months of treatment. No recurrence was observed at an 8-month average follow-up. CONCLUSION: The preliminary clinical study confirms the feasibility of this tension-free repair and the effectiveness of this composite A-shaped mesh.

The purpose of our study was to identify general factors and distinctive clinical features differentiating patients with chronic cluster headache (CH) evolved from episodic CH and patients with episodic CH. Our study sample included 28 patients suffering from chronic CH evolved from episodic CH and 258 patients with episodic CH; all were referred to the Headache Center of Parma between December 1975 and June 1998. Patients with episodic CH were selected from all episodic CH referrals (n = 485) and selection was based on the duration of the disorder, which was to exceed the average period needed for an episodic form to turn into a chronic form (4.5 years for females and 7.0 years for males). At CH onset, the mean age for patients with chronic CH evolved from episodic CH was older than for those with episodic CH. Among patients with chronic CH, more were smokers or heavy drinkers, and had suffered a head injury. Clinically, episodic CH evolving into chronic CH was characterized by a high frequency of cluster periods, a larger proportion of patients with attacks not occurring strictly within cluster periods, and remission periods lasting less than 6 months. Possible predictive factors in the development of chronic CH appear to be CH onset from the third decade of life onward, the occurrence of more than one cluster period a year, and the short-lived duration of remission periods. The role played by head injury and cigarette smoking in the evolution of the disorder still cannot be established with certainty.

The International Headache Society (IHS) classification divides chronic cluster headache (CH) into two subtypes: chronic CH unremitting from onset (CCHU) and chronic CH evolved from episodic (CCHE). The purpose of our study was to point out any similarities and differences between the two chronic CH subtypes and to determine whether or not they can be considered as two separate clinical entities. We reviewed data about 31 CCHE patients and 38 CCHU patients referred to the Parma Headache Centre between 1975 and 1999. Clinically, CCHE patients exhibited statistically significant differences from CCHU patients, i.e. earlier CH onset and duration of attacks varying more frequently between 120 and 180 min. From the point of view of lifestyle, heavy alcohol and coffee drinkers prevailed among CCHU patients, while CCHE patients were more frequently heavy smokers. Based on clinical features, it seems reasonable to suppose that chronic CH may occur as two distinct entities.

The purpose of our study was to determine whether or not patients reporting weekend headache exhibit distinctive features in their work habits, family life, and leisure on workdays and on weekends as compared to other headache sufferers, and whether or not they are inclined to change their living habits at the weekend. The study was done on an initial sample of 50 patients referred to the University of Parma Headache Centre between October 1996 and April 1997. These patients completed a specially designed questionnaire which, in addition to demographics, contained specific questions relevant to the subject matter being investigated. They were also given a diary which they had to complete for 8 consecutive weeks in order to determine the actual frequency of headache attacks over different days of the week. The questionnaire data were only analyzed for the 38 women in the sample, because there were too few male controls for an accurate comparison with weekend headache sufferers. Among the women with weekend headache, work habits, family life, and leisure were such as to suggest a possible increase in stress and frustration on weekends, which might have made them perceive the headaches occurring on Saturdays and Sundays as more severe. No changes were found in the intake of substances such as coffee and alcohol, nor in cigarette smoking over the different days of the week. Finally, analysis of the diaries showed an increased frequency of headache attacks on weekends only among the men, which seems to corroborate the hypothesis of weekend headache as a disorder typically affecting men.

The Authors analyze a series of 441 patients affected by carcinoma of the colon operated on between June 1980 and November 1993. The incidence of the different stages of the disease according to Dukes resulted comparable to that reported in the literature as well as the incidence of morbidity and mortality. Recostruction was performed in all cases with mechanical sutures (T-L for the right colon and L-T for the left colon) and without protection enterostomy. Long-term results evaluated by actuarial methods were influenced by the stage of the disease, and not by sex or duration of symptoms. The need of early diagnosis as well as oncologically correct surgical technique is furthermore confirmed. The importance of clinical trials on adjuvant chemotherapy is emphasized in order to improve survival in patients operated for stage B and C colon cancer.

The treatment of liver metastases should be addressed in a multidisciplinary way, considering the manifold therapeutic options available, for each of which corresponds a particular indication. The best results are obtainable with resective surgery in cases in which there is a partial involvement of the liver (25-50%) and a variable intra-hepatic distribution (monolobar), situations that correspond to Gennari stages I and II. In the authors' experience, the extent of the liver resection does not influence possible survival and oncologically correct resections should be carried out such as segmentectomies, pluri-segmentectomies or wedge resection in compliance with the principle of removing at least 1.5 cm of healthy perineoplastic tissue. The authors reserve major hepatectomies to special situations: voluminous metastases, diffuse involvement of a single lobe, topographic localisation contraindicating segmentary resection.

Operative hysteroscopy procedures can present complications connected to necessity of kneeping, usually with low viscosity fluids, an uniform distension of uterine cavity. The instilled solutions are reabsorbed through the peritoneum and open uterine venous channels producing a hyperhydration syndrome. The case report shows the rising up of tis syndrome during a hysteroscopy for an uterine myoma resection. The physiopathology includes cardiovascular overload and haemodilution, causing pulmonary, cerebral and tissutal oedema. In this case report the volumes of arterial oxygen saturation and end tidal carbon dioxide obtained on line were the first warning signals. A high CVP value, a plasmatic reduction of Na, albumin, proteins, haemoglobin, haematocrit and osmolarity reflected the excessive fluid reabsorption. For this reason the necessity, during these surgical methods, of considering some practical indications and the absolutely necessary use of clinical and biochemical monitoring systems for these patients.

The authors retrospectively evaluate their 10-year experience in the surgical management of pancreatic cancer, and analyze their results in terms of morbidity and long-term survival. The comparison between curative and palliative surgery shows, in this series, a better long-term survival and a better performance status for the patients in the curative group, although postoperative morbidity and mortality are higher. The difficulty of an early diagnosis as well as a correct preoperative staging is confirmed. Finally, the authors propose a personal, totally mechanic technique of digestive tract restoration after gastric resection during pancreatic surgery underlining this procedure is easy, safe, fast and functional.

Primary and metastatic gastrointestinal tumours in the liver have been treated by intrahepatic artery infusion of chemotherapeutic drugs in an attempt to increase the efficacy of the administered agents. Among the several active agents, 4' epidoxorubicin, an anthracycline analogue, was selected for this study because of the therapeutic level reached in the liver by this drug. Seven patients with primary hepatic carcinoma and twenty with metastatic adenocarcinoma of the colon to the liver received intraarterial hepatic infusion of epidoxorubicin at the dosage of 30 mg weekly. No haematological or gastrointestinal grade 3-4 toxicity was recorded, only one patient experienced transient cardiac toxicity. No objective response was observed in primary hepatic carcinoma and six objective responses, 1 complete and 5 partial (30%), were achieved in metastatic colorectal cancer patients. This results is not far from those reported with FUDR, but does not justify epidoxorubicin in colorectal cancer patients as first line intraarterial treatment.
