Sarcoidosis is a systemic disorder characterized by granulomatous lesions, principally affecting the lungs. There are numerous reports in the literature of an associated involvement of the thyroid, much more frequently in hypothyroid than in hyperthyroid subjects. The present case report refers to a woman presenting with thyroid nodules and normal biochemical levels and thyroid function parameters, while histology revealed sarcoid-type lesions. Subsequent investigations and a long follow-up showed no evidence of involvement of other sites, including the lungs. Consequently, after a long period of normal health associated with the negative results of the examinations, a diagnosis of sarcoidosis limited to the thyroid was proposed, which was cured by thyroidectomy.

Purpose: The maximum resting pressure in the anal canal is greatly raised after hemorrhoidectomy. This increase is likely to be the cause of postoperative pain, which is still the most troublesome early problem after hemorrhoidectomy. This study was designed to compare, after hemorrhoidectomy, the effects of intrasphincter injection of botulinum toxin vs. application of glyceryl trinitrate ointment in improving wound healing and reducing postoperative pain at rest or during defecation., Methods: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 40 days after hemorrhoidectomy. One group received one injection containing 20 IU of botulinum toxin, whereas the other an application of 300 mg of 0.2 percent glyceryl trinitrate ointment three times daily for 30 days., Results: Five days after hemorrhoidectomy, maximum resting pressure was significantly reduced compared with baseline values in both groups (85 +/- 15 vs. 68 +/- 11 mmHg for the group treated with botulinum toxin, 87 +/- 11 vs. 78 +/- 11 mmHg for the group treated with glyceryl trinitrate ointment). Overall analysis of postoperative pain at rest showed a significant reduction in the botulinum toxin group vs. glyceryl trinitrate group, whereas pain during defecation and time of healing were similar. Adverse effects, such as headaches, were observed only in the glyceryl trinitrate group. Forty days after hemorrhoidectomy in the glyceryl trinitrate group, maximum resting pressure values were similar to preoperative ones, whereas the values were still reduced in the botulinum toxin group., Conclusions: A single intrasphincter injection of botulinum toxin was more effective and safer than repeated applications of glyceryl trinitrate in reducing early postoperative pain at rest but not during defecation.

Background: Pilonidal sinus (PS) disease of the sacrococcigeal region is an acquired condition resulting from penetration of shed hair shafts through the skin. Different types of operations have been described in the letterature. More recently fibrin glue has been used with succesfull. Aim of this study was to assess the effectiveness of fibrin glue for the treatment of pilonidal sinus., Patients and Methods: Eight patients age ranged 21,8 +/- 6,5 affected by PS disease of sacrococcigeal region were included in this study. All patients undergoing surgical operation under local anaesthesia. Following administration of 1% methylene blue through the main opening, a small vertical elliptical incision is maked including the entire sinus opening and an excision of PS was performed without entering the sinus cavity, removing a minimal amount of subcutaneous tissue. Afterwards the highly concentrated fibrin glue, containing 1,000 U/ml of thrombin was applied to cover the wound. Post-operative pain, analgesic consumption, duration of hospital stay, failure healing, the rate and time of recurrence, time to healing, time to return to work and post-operative complications were recordered., Results: All patients expressed satisfaction with the procedure. Mean hospital stay was 5.4 +/- 2.1 hours. Healing was achieved after 25.8 +/- 13.2 days. The post-operative pain mean score was 3.8 +/- 2.1 in first day, 2,9 +/- 1,8 in third day and 1,3 +/- 0,8 in the seventh day. The mean analgesic consumption per week was 5,6 +/- 3,2 medications. Mean time to return to work was 5,3 +/- 2,1 days., Conclusion: The minimal excision of PS and application of fibrin glue is a non-invasive effective treatment, easy and simple to performe and not associated to recurrences. For these reasons this procedure in our opinion as the first line treatment for pilonidal sinus disease.

Granular cell tumor (GCT) was described for the first time by Abrikosoff in 1926. It is a relatively rare neoplasm that may occur at many sites, but most commonly in the skin or soft tissues. The occurrence of GCT in the gastrointestinal tract is rare, accounting approximately for 8% of all tumors, among which the most common site is the esophagus, whereas gastric localization is very rare. Gastric GCTs can be solitary or, more frequently, associated with other gastrointestinal localization. Although GCTs are usually clinically and histologically benign, some malignant cases have been reported. Histologically, these tumors consist of polygonal and fusiform cells disposed in compact "nests" and immunohistochemical staining for S-100 protein supports the proposed derivation from Schwann cells. A correct preoperative diagnosis of this tumor can only be made in 50% of all patients and it is always based on endoscopic biopsy. Laparoscopic or conventional wedge resection represents the treatment of choice. In this study, the authors reported a case of a 49-year-old woman with a solitary granular cell tumor of the stomach with infiltrative pattern, successfully treated with surgical resection. A review of literature is also presented with emphasis on diagnostic criteria concerning the malignant form.

Background: The aim of this study was to evaluate changes in the production of some cytokines (interleukins [ILs]-6, -10, -1, and -1ra), vascular endothelial growth factor, and beta-fibroblast growth factor after polypropylene mesh implantation., Methods: Twenty female patients were divided into 2 groups. In 1 group, hernia repair was performed with conventional sutures (CR), whereas in the other group polypropylene mesh (MR) was used. Growth factors and cytokines production was analyzed in wound drain fluids based on the amount produced during 24 hours., Results: IL-1 increased substantially in MR patients on postoperative days 1 and 2. IL1-ra and IL-10 production was always significantly higher in CR patients. IL-6 production did not show any considerable difference between the 2 groups. Vascular endothelial growth factor production was significantly higher in the MR than the CR group at all time points, whereas beta-fibroblast growth factor production was higher in the MR than the CR group only on postoperative day 1., Comments: Our data suggest that different surgical procedures induce various levels of inflammation and that implantation of prostheses significantly stimulates the inflammatory response.

Knowing the dynamics of growth factor and cytokine secretion within the site of a surgical operation is important, as they play a crucial role in the pathophysiology of wound healing and are a target for modifying the repair response. The aim of this study was to evaluate the production of several cytokines and growth factors in the drainage wound fluid from patients undergoing incisional hernia repair: namely, interleukin (IL)-6, IL-10, IL-1alpha, IL-1 ra, interferon-gamma, vascular endothelial growth factors and basic fibroblast growth factor. Ten female patients with abdominal midline incisional hernia undergoing surgical repair were included in this study. In all cases, a closed-suction drain was inserted in the wound below the fascia and removed on postoperative day 4. Wound fluid was collected on postoperative days 1-4 and the amount was recorded each time. Growth factors and cytokines production was evaluated as the whole amount produced over a 24-hour period. In all patients, the amount of drain fluid from surgical wounds was more copious the first day after surgery, it decreased significantly afterward. The presence of all cytokines was highest on postoperative day 1, decreasing over the following days. More specifically, the production of IL-1 ra, IL-6, IL-1alpha, and IL-10 on postoperative day 1 fell sharply on postoperative days 3 and 4, whereas, after an initial reduction, interferon-gamma showed an increase from day 2 onward. Vascular endothelial-derived growth factor production increased progressively after the operation reaching statistical significance only on day 4. As for basic fibroblast growth factor, it showed an opposite pattern: it was higher on postoperative day 1 decreasing thereafter. This analysis of cytokine and growth factor production in the drain fluid will lead us to a better evaluation of the events that follow a surgical wound and to a better understanding of the healing process.

The number of old and oldest old patients undergoing surgery of varying severity is increasing. Ageing is a process that changes the performances of most physiological systems and increases susceptibility to diseases and death; accordingly, host responses to surgical stress are altered with ageing and the occurrence of age-related increase in susceptibility to post-operative complications has been claimed. Twenty-four male patients undergoing Lichtenstein (LH) hernioplasty for unilateral inguinal hernia were included in this study and divided in two groups (Young and Old respectively), according to their age. As expression of the acute phase response, we measured changes in concentration of pro-inflammatory cytokines Tumor necrosis factor-alpha and Interleukin-1beta, leukocytes, acute phase proteins C-reactive protein and alpha 1-antitrypsin. Elderly humans showed prolonged and strong inflammatory activity compared to younger subjects in response to surgical stress, indicating that the acute-phase response to surgical stress of elderly humans varies from that of the young, showing initial hyperactivity and a delayed termination of the response. Thus, the acute phase response to surgical stress is higher in old subjects, but the clinical significance of this remains unclear. It is not known whether a causal relationship exists between this stronger acute phase response and the increases in susceptibility to post-operative complications observed in aged patients.

The association between angiodysplasia (AD) and von Willebrand's disease (vWD) was first described by Quick in 1967. The clinical course of patients with vWD and AD is characterized by multiple admissions to hospital for gastrointestinal bleeding, necessitating transfusions of packed red cells, factor VIII, and von Willebrand factor concentrates. The therapeutic management of these patients is difficult. Both medical and endoscopic techniques have been tried, but no treatment modality has been completely successful. We describe the clinical course of a patient affected by vWD, who suffered repeated massive gastrointestinal bleeding caused by small bowel AD. Intestinal resection was the only effective treatment, resulting in complete remission of the gastrointestinal bleeding.

Purpose: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play an important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemorrhoidectomy in reducing the maximum resting pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation., Methods: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward in all patients undergoing Milligan-Morgan hemorrhoidectomy. One group received an injection of 0.4 ml of saline into the internal anal sphincter, the other group were injected with 0.4 ml of solution containing 20 units of botulinum toxin., Results: After five days from hemorrhoidectomy, maximum resting pressure decreased in the group injected with botulinum toxin and increased in the placebo group. The time of healing and postoperative pain when resting and during defecation significantly decreased in the group treated with an injection of botulinum toxin., Conclusions: Botulinum toxin injection into internal anal sphincter after hemorrhoidectomy is effective in reducing maximum resting pressure, time of healing, and postoperative pain both on resting and during defecation in absence of complications or side effects.

Background: Angiogenesis is strongly influenced by vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (b-FGF), whose production is also regulated by interferon (IFN)-gamma and interleukin (IL)-10. The aim of this study was to evaluate the modifications of serum VEGF, b-FGF, IFN-gamma and IL-10 levels in patients with inguinal hernia undergoing hernioplasty with the Lichtenstein technique (LH) using polypropylene mesh or with Bassini open conventional inguinal hernia repair (BH)., Materials and Methods: Randomly, 16 patients underwent BH, and 16 were treated with the LH technique using polypropylene mesh. Blood samples were collected 24 h prior to surgery and then 6, 24, 48 and 168 h postoperatively. The serum concentrations of VEGF, b-FGF, IFN-gamma and IL-10 were evaluated., Results: In BH patients, a peak of VEGF synthesis at 6 h with a normalization of this parameter 24 h after surgery has been observed. In the same subjects, b-FGF synthesis increased after surgery reaching significant levels 48 h later. On the contrary, in LH patients, a decrease in the serum VEGF and b-FGF concentrations was detected after surgery and their increase afterwards. IL-10 was increased in both groups 6 h after operation and declined to preoperative levels 24 h afterwards. IFN-gamma enhanced in LH patients 6 h after surgery, whereas no modifications were detected in BH subjects., Conclusions: This preliminary study shows that VEGF and b-FGF modifications, associated with alterations of cytokine secretion, are detectable in human undergoing hernioplasty, and suggests that they could somehow influence in the wound-healing process.

Background: The purpose of this study was to assess the modifications of interleukin (IL)-6, C-reactive protein (CRP), leukocytes and fibrinogen after implantation of polypropylene mesh., Methods: Thirty-six patients were included in this study and divided into two groups. To the first group were allocated patients affected by inguinal hernia and undergoing conventional repair (subgroup Ia) or hernioplasty with 40-cm(2) polypropylene mesh (subgroup Ib). To the second group were allocated patients affected by incisional hernia and undergoing conventional repair (subgroup IIa) or incisional hernia repair with 400-cm(2) polypropylene mesh (subgroup IIb). Peripheral venous blood samples were collected 24 h before surgery and then 6, 24, 48 and 168 h postoperatively., Results: We present evidence that serum levels of IL-6, CRP, leukocytes and fibrinogen were significantly increased postoperatively in all subgroups compared with their baseline values. In particular, the production of inflammatory mediators was higher in subgroups Ib vs Ia and IIb vs IIa. Comparing the entities of the inflammatory responses among various groups we found that it was clear that they were similar in subgroups Ib and IIa, and that the highest were in subgroup IIb and the lowest in subgroup Ia., Conclusion: The data show that conventional inguinal and incisional hernia repair induces an inflammatory response, which is smaller than that observed if both operations are carried out with polypropylene meshes. Furthermore, the results suggest that a larger mesh is associated with a higher production of inflammation mediators.

Wound healing is a complex process involving interaction between different cell types, such as growth factors. Among these, vascular endothelial growth factors (VEGF) and basic fibroblast growth factors (b-FGF) are the most important. The aim of this study was to assess the production of VEGF and b-FGF in wound drainage fluid from patients undergoing incisional abdominal hernia repair. Ten female patients with abdominal midline incisional hernia undergoing surgical repair were included in this study. In all cases a closed suction drain was placed in the wound below the fascia and removed on postoperative day 4. Wound fluid was collected on the I, II, III and IV day and its amount at each time was recorded. VEGF and b-FGF production were evaluated as the quantity produced in 24 hours. In all patients the amount of drainage fluid from the surgical wound was highest on the I day after surgery, after which there was a significant reduction. VEGF production increased progressively after the operation proving significantly higher only on the IV day. The amount of b-FGF, in contrast, was higher on the I day, decreasing thereafter on the following postoperative days. Analysis of the production of growth factors in the drainage fluid has enabled us to better assess the events that occur following surgical wounds and has confirmed the physiology of the healing process and the possible use of these factors in modulating positive healing.

Background and Aim: Cytokines are part of a family of molecules involved in the initiation, control and termination of the events that occurs in wound healing process. Aim of this study was to evaluate the production of some cytokines [interleukin (IL)-6, IL-10, IL-1alpha, IL-1ra, interferon (IFN)-gamma] in the drainage wound fluid from patients undergoing incisional hernia repair., Methods: Ten female patients with abdominal midline incisional hernia undergoing to surgical repair were included in this study. In all cases a closed suction drain was placed in the wound below the fascia and it was removed on the 4th postoperative day. Wound fluid was collected on the 1st, 2nd, 3rd and 4th day and its amount in each time was recorded. The production of IL-6, IL-10, IL-1alpha, IL-1ra and IFN-gamma were evaluated as quantity produced in 24 hour., Results: In all patients the amount of drain fluid from surgical wound was highest on the 1st day after surgery, afterwards there is a significant reduction. The production of all cytokines evaluated was highest on the 1st day decreasing on the 2nd day except for IL-1alpha that not show any modification. The produciton of IL-1ra, IL-6, IL-1alpha and IL-10 was significantly reduced on the 3rd and 4th postoperative day in comparison with the respectively values recorded on the 1st day, whereas IFN-gamma levels were similar., Conclusions: The dosage of cytokines in the drain fluid led us to better evaluated the events that follow surgical wound and their analysis offers further information in the role of cytokines in healing process, with the goal to get supportive treatments to promote the best evolution.

The aim of the study was to evaluate whether topical application of 0.2% glyceryl trinitrate ointment could reduce post-haemorrhoidectomy healing time and pain both at rest and during defecation. Thirty patients with grade III and IV haemorrhoids were included in the study and divided into two groups. All patients underwent Milligan-Morgan haemorrhoidectomy, and anorectal manometry was performed before surgery and after 5 and 30 days. In one group a placebo ointment was applied to the perianal wounds, while in the other group a 0.2% glyceryl trinitrate ointment was used. Maximum resting pressure was reduced in the glyceryl trinitrate group and increased in the placebo group after 5 days. Postoperative pain both at rest and during defecation, and the time to healing and return to normal activity were significantly reduced in the glyceryl trinitrate group, whilst analgesic consumption was similar. An elevated incidence of headache was observed In the glyceryl trinitrate group. Topical application of glyceryl trinitrate was effective in reducing postoperative pain and healing time, but the substantial incidence of side effects may limit its extensive use.

Background: Postoperative pain associated with Milligan Morgan haemorrhoidectomy (MMH) remains problematic. Most patients complaint a severe pain on defecation and in the 1st postoperative week because of secondary infection and sphincter spasm. We studied the effect of metronidazole, lactulose and glyceryl-trinitrate on pain after MMH., Method: Thirty patients were randomly assigned to two groups. The 1st received a treatment with oral laxative (lactulose 66.7%) metronidazole and a topical glyceryl-trinitrate ointment at 0.2% both pre and postoperative; the 2nd received a placebo at the same dosage. The amount of pain in the 1st week and at the time of two defecation, postoperative analgesic requirement and time to return to normal activities were documented., Results: A significant differences in the score pain on 2nd and 3rd day and on the 1st two defecation were observed among group. Analgesic consumption was highest in the placebo group., Conclusion: The treatment with lactulose, metronidazole and topic glyceryl-trinitrate in patients undergoing MMH, seems to reduce secondary pain and increase patients satisfaction and earlier return to work with improvement of cost and benefit.

Free perforation in abdominal cavity in patients with Crohn's disease is a rare entity as attested from the data reported in the literature. It is a very dangerous event and requires a surgical urgency management. The Authors reported two cases of free perforation, in patients with Crohn' disease, undergoing surgical operation in urgency. Analyzing pathogenesis, difficulty in diagnosis making and therapeutic choices, they underline that CT is very useful in the diagnosis, while resection of the perforated intestinal tract represent the best surgical treatment.

Abdominal cystic lymphangiomas are a rare pathology that are related to abnormal development of the lymphatic system. They predominate in a children and are very uncommon in adults. Here the authors report a case of a cystic intra-abdominal lymphangioma in a 64-years old woman in which the cyst was situated in the mesentery of the jejuneum, with rapid growth. Ultrasonography, computed tomography and magnetic resonance imaging led us to evaluate a cystic characterizations and his site. Surgical excision remain the treatment of choice because we can establish an histologic diagnosis. Complete surgical excision of cyst, although it can be difficult, consent a definitive healing.

Internal abdominal hernias are a rare entity and may cause unexplained abdominal pain. This report concerns a 46 year old male patient, with a four year history of episodic colicky peristaltic abdominal pains, in whom a left paraduodenal hernia was found at surgical exploration after a negative diagnostic screening by ultrasound, CT and small bowel enema. Upon laparotomy the Authors found a left-sided paraduodenal hernia with an empty herniated sack. Repair of the hernial defect resulted in the complete and stable resolution of abdominal symptoms. The importance of considering paraduodenal hernias in the differential diagnosis of unexplained intermittent abdominal pain is discussed.

Introduction: Milligan-Morgan haemorrhoidectomy is considered the best treatment for hemorrhoidal disease. Although this, many patients complaint post-operative pain that remain the worse complication. For this reason different are the trials performed in order to reduce his intensity. In this report we want to evaluate if the use of ultrasonic scalpel to perform Milligan-Morgan hemorrhoidectomy, compared with conventional surgery, could reduce post-operative pain., Materials and Methods: 30 patients with III and IV degree of haemorrhoids were included in this study and divided in two groups. In the first group Milligan-Morgan haemorrhoidectomy was performed with conventional instruments, while in the second group the some procedure was performed with ultrasonic scalpel. The duration of intervention, time hospitalization, the time to open alvus to stools, the time to return to normal activity, the complications, pain and the amount of analgesic consumption were evaluated., Results: In the II group's patients, it was observed a reduced time to healing with reduced spread of necrosis and inflammatory pattern, associated with reduced post-operative pain and the lower analgesic consumption., Conclusions: The use of ultrasonic scalpel to perform Milligan-Morgan haemorrhoidectomy, compared with conventional instruments, reduce post-operative pain making a more short time to healing and a precocious time to return to normal activity. For this reason we believe that the use of ultrasonic scalpel, although a more elevated costs, seems to be advantageous.

A case of 28 years woman with nipple's leiomyoma we report. Only 38 cases are reported in the literature. This neoplasm presents a difficult differential diagnosis with the remaining flogistic and neoplasm breast and nipple disease.

The modifications of IL-6. CRP, ceruloplasmin, alpha 1 antitrypsin, fibrinogen, transferrin, albumin and leukocytes counts have been evaluated after traditional open cholecystectomy (OC) or laparoscopic cholecystectomy (LC). Forty-two patients were included in this study, 20 underwent to OC and 22 underwent to LC. Serum samples were performed before surgery and at distance of 6, 24, 48 and 168 hours. The results show a more significant increase in acute phase inflammatory response after OC compared with LC as attested by highest values of leukocytosis, IL-6, CRP, fibrinogen and alpha 1 antitrypsin and lower levels of albumin. In conclusion, after LC, the phase acute response is attenuate and it can explain the reduced period of convalescence of patients treated with LC.

A phase II study in patients with stage IIIB/IV non-small cell lung cancer (NSCLC) was carried out to evaluate the clinical activity and toxicity of the chemotherapeutic combination of gemcitabine+vinorelbine (GEM/VNR). Forty-five patients (40 male, 5 female) with a median age of 67 years (range 37-73) and a median ECOG performance status of 1 (range 0-2) were enrolled into the trial. Twenty patients had stage IIIB (two positive supraclavicular nodes and 20 cytologically positive pleural effusion), and 25 had stage IV NSCLC. GEM 1000 mg/m(2) diluted in 250 cc(3) of normal saline was administered iv on days 1, 8, and 15, while VNR was given 30 mg/m(2) on days 1 and 8 every 4 weeks. The median number of courses/patient was 4 (range 3-7). According to an intent-to-treat analysis 2 (4%) patients had a complete response and 16 (36%; 95% CL 22-52%) had a partial response for an overall response rate of 40% (95% CL 26-56%). Twelve (27%) patients had stable disease and 15 (33%) were considered as treatment failures. Median overall survival of the whole series was 8+ months with 33% of patients alive at 1 year. Toxicity was generally mild. WHO grade 3-4 neutropenia was recorded in 22% of cases, grade 1-3 liver toxicity in 6% of patients and neutropenia-unrelated fever in 9%. This multicentre phase II study suggests that the GEM/VNR combination regimen is an active and well tolerated regimen in patients with stage IIIB/IV NSCLC. Larger studies comparing cisplatin-based regimens to new schedules without cisplatin are warranted.

The advantages of laparoscopic (LC versus, open cholecystectomy (OC) seems to be related to minimal invasive procedure and to the moderate inflammatory response. The aim of this study is to define the involvement of Th1 (IFN-gamma) and Th2 (IL-4, IL-6, IL-10, IL-13) cytokines production in vivo and in vitro in patients undergoing OC or LC. In 42 patients undergoing LC (n = 22) and OC (n = 20) Th1-like and Th2-like was evaluated before operation and at 6, 24 and 48 hours after operation for white blood cell counting and cytokines (IL-4, IL-6, IL-10, IL-13, IFN-gamma, TNF-alpha) in the sera and in the supernatants from circulating mononuclear cells stimulated with phytohemagglutinin or lipopolysaccharide. The acute phase response cytokine, IL-6, appeared significantly increased following OC than after LC. All other cytokines did not very significantly. In vitro data shows a reduction of IFN-gamma and increase in Th2-like cytokines in OC patients compared with the basal value. In LC subjects we observed an high production of IFN-gamma associated to an increase of Th2-like cytokines, like IL-10 and IL-13, even though IL-4 and IL-6 were unmodified. In contrast to OC, LC did not significantly affect immunocompetence, maintaining a moderate inflammatory response and an adequate balance between Th1 and Th2 cytokine. Furthermore, the strong activation of cells producing Th1-like cytokines in LC patients following mitogen activation indicated a consistent anti-microbial activity, that was not detectable in OC patients, that showed after activation only a Th2 response.

We report the case of a 53-year-old man with inflammatory pseudotumor (IPT) of the liver and spleen. This concomitant association has rarely been reported. The patient presented with a hypoechoic mass in the liver and a clinical picture of recurrent sepsis; hematochemical exams and imaging data were nonspecific. Antibiotic therapy improved the clinical course, but did not resolve it definitively. After 50 days of therapy, as the hepatic mass decreased a similar lesion appeared in the spleen. The final diagnosis was made on splenectomy and an intra-operative biopsy of the residual liver lesion. The diagnostic problems encountered in this very rare association of IPT of the liver and spleen were similar to those for isolated IPT in the respective single organ sites. After 15 months of follow-up, the patient is in good health and no recurrence of symptoms or masses has been observed.

Background: The purpose of this study was to evaluate the involvement of proinflammatory cytokines (interferon-gamma [INF-gamma], interleukin [IL]-6) and anti-inflammatory cytokines (IL-4, IL-l0, IL-13) in patients undergoing Lichtenstein tension-free hernioplasty (LH) using polypropylene prosthetic materials or conventional Bassini hernia (BH) repair., Methods: Thirty-five male patients (age range 25 to 60 years) with unilateral inguinal hernia without complications or recurrence were included in this study. Randomly, patients underwent conventional operation and had their inguinal hernia repair performed with polypropylene mesh. Peripheral venous blood samples were collected 24 hours prior to surgery and then 6, 24, 48, and 168 hours postoperatively. Fifteen healthy controls were included., Results: We present evidence that LH patients showed both an increased serum level of Thelper 1 (Th1)-like cytokines (IFN-gamma) and an increase in Thelper 2 (Th2)-like cytokines (IL-6 and IL-l0), associated with a slight reduction of peripheral blood mononuclear cells (PBMC) producing IL-6 and a normal level of PBMC producing IFN-gamma, IL-l0, IL-13, and IL-4. Whereas BH patients showed in part an amplification of Th2-like cells, characterized by the sustained serum production of IL-6 and IL-l0, associated with an increase in IL-l0 secreted by in vitro stimulated PMBC., Conclusions: Our data show that LH is associated with a higher production of inflammatory cytokines (IFN-gamma and IL-6) compared with BH, likely induced by the presence of the polypropylene prostheses.

Objective: The authors report their experience about the endoscopic treatment of upper gastrointestinal bleeding from Dieulatoy's ulcer (non variceal bleeding)., Design: Report of 5 cases; evaluation of mortality and effectiveness of the treatment., Setting: Operative Unit of General and Thoracic Surgery, Department of Surgical, Anatomical and Oncological Disciplines. Policlinico, University of Palermo., Interventions: EGDS + sclerotherapy (emergency room) in all 5 patients., Results: 80% successful (stop bleeding)., Conclusions: Endoscopic sclerotherapy is choice treatment of upper gastrointestinal bleeding from Dieulafoy's ulcer, only in well experienced teams and rapidly.

Some cases of Ménétrier's disease associated with Helicobacter pylori (HP) have recently been reported in the literature. We report here the case of a 51-year-old man with a diagnosis of Ménétrier's disease who had previously been unsuccessfully treated with H(2) antagonists. A subsequent demonstration of HP infection led us to treat the patient with an eradicating therapy which prompted complete regression of clinical symptoms, resolution of the gastric endoscopic picture, and absence of HP on gastric histology. This result, in accordance with others in the literature, indicates an eventual association of HP infection with Ménétrier's disease and that consequent therapy is mandatory., (Copyright 2001 S.

Inflammatory pseudotumor is rare benign lesion ad uncommon is a multiple localization of the liver and spleen. We report a case of inflammatory pseudotumor of the liver associated with an other lesion in the spleen, a 53-years-old ma in which we observed the evolution of clinical picture. Making the diagnosis is often difficult, despite the use of the modern imaging and laboratories techniques, and generally these masses often confuse with others lesions, such as primary or secondary neoplasm, because the clinical presentation and morphological appearance are often unspecific. The medical treatment seems to be more appropriate for patients when it is possible make a correct diagnosis with a biopsy of the lesion. In the other cases, the surgical procedure is the best treatment that must be supported by histologic examination.

Background: The purpose of this study was to evaluate the involvement of inflammatory mediators in patients undergoing Lichtenstein tension-free hernioplasty (LH) using polypropylene prosthetic materials or conventional Bassini hernia repair (BH)., Methods: Thirty patients male with unilateral inguinal hernia without complications or recurrence were included in this study. Randomly, patients underwent LH or BH. Peripheral venous bloods samples were collected 24 hours prior to surgery and then 6, 24, 48 and 168 hours postoperatively., Results: We present evidences that LH patients showed a higher increased serum level of fibrinogen, C-reactive protein, alpha-1-antitrypsin, and interleukin-6 than BH patients. Postoperative visual analogue scales for pain were reduced on mobilization for patients undergoing LH compared with BH. Neutrophils were significantly increased only in LH compared with baseline. Ceruloplasmin, transferrin, and albumin levels were unmodified after BH or LH., Conclusions: In conclusion our data show that although LH induces less pain and more rapid postoperative recovery, it is associated with an higher inflammatory response compared with BH, likely due to polypropylene mesh.

Cell-mediated immunity (CMI) is temporarily decreased after major surgical procedures in relation to type of anaesthesia, length and severity of an intervention. In this study it has been evaluated CMI response in vivo, after laparoscopic (LC) and open cholecystectomy (OC). 5 healthy persons and 16 patients with symptomatic and uncomplicated gallstones were studied. They were subdivided in two groups: 8 were treated by OC, 8 by LC. A skin test system (Multitest, IMC-Institute Merieux, Lyon, France) consisting of a plastic disposable multiple-puncture device capable of simultaneous application of seven delayed-type hypersensitivity antigens and a glycerin and saline diluent (negative control) was used. The test was performed 48 hours before and 24 hours after the surgical procedure. A diameter of 2 mm or more of the induration was considered as a positive response. A score expressed, as the sum in millimeters of all the mean diameters (DM) of positive reactions and as numbers of antigens (NA) positive was calculated. Statistics was assessed by Student's t test for comparison of averages. There was no difference of age, sex, anesthesiologic risk, length of the operation between the two groups. We observed a significative reduction of DM (P < 0.05) and of NA (P < 0.05) in patients in which OC was performed while there were no significant in the group treated by LC. Results show a significant suppression of the CMI after OC, no particular changes after LC according to other studies in vitro.

Background: Deep-vein thrombosis (DVT) and pulmonary embolism (PE) are the most important causes of morbility and mortality in patients submitted to surgical intervention: some peculiar factors of laparoscopic surgery can modify their risk. The aim of this study is to evaluate possible variations of the fibrinolytic system after cholecystectomy., Methods: Eighteen patients affected by symptomatic and non-complicated gallstones have been included in this study. They were divided into two groups of nine patients each: the first group was submitted to laparoscopic cholecystectomy (LC) and the second to open cholecystectomy (OC). Antitrombin III (ATIII), fibrinogen degradation products (FDP), tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI) have been evaluated preoperatively and 6, 12, 24 and 48 hours after the operation., Results: The levels of ATIII did not present significantly variations. The FDP in both groups were significantly increased 48 hours after open cholecystectomy. Levels of PAI instead were increased in comparison to the basal values at 6, 12, 24, 48 hours with p < 0.05; p < 0.01 and p < 0.05 respectively in patients submitted to OC, in the LC group no variations were observed; a comparison between the groups showed a significant modification (p < 0.05) only at the 12th hour., Conclusions: The early mobilization of patients in the postoperative course and the lower invasion of LC can oppose the prothrombotic effect in the lower limbs.

A 30 degrees reverse Trendelenburg position and the pneumoperitoneum performed in patients undergoing at Laparoscopic Cholecystectomy (LC) cause haemodynamic modifications in inferior cava vein and in femoral veins producing a venous stasis in lower limbs. So that activation of coagulation with hypercoagulability occurs. The aim of this study is to value the modification of the haemocoagulative and fibrinolytic factors during LC and OC. 18 patients with symptomatic and non complicated lithiasis were examined. They were divided in two groups, nine patients for each group. LC was performed in first group and OC in the other group. Prothrombin time (PT), plasma-activated partial thromboplastin time (PTT), Antithrombin III (AT III) fibrinogen degradation products (FDP) were valued before and at 6, 12, 24, 48 hours after operation. For the statistical analysis Student "t" for average comparison was used. There were no relevant alterations of PT, PTT and ATIII after operation in the two groups. FP was increased after surgery, especially at 24th-48th hours in the group in which OC (p < 0.05) was performed. FDP were increased in both groups but only at 24 and 48 hour after OC (p < 0.05) the result was significant. Earlier mobilization and reduced invasivity of laparoscopy could contrast thrombotic effects of the blood stasis in the lower limbs when 30 degrees-45 degrees reverse Trendelenburg and pneumoperitoneum are performed.

The authors report a case of agenesis of gallbladder associated with lithiasis of common bile duct. A review of the literature confirms the rarity of this congenital malformation. In 40-60% of cases it is associated with other gastrointestinal, skeletal, cardiovascular and genitourinary malformations. In 20-50% of cases it can be associated with common bile duct stones. Patients are asymptomatic in the majority of cases. A preoperative diagnosis is difficult despite of high accuracy of the modern diagnostic imaging techniques.

A case of intersigmoid hernia, personally observed is described, The various aspects of this pathology are examined and the imprecise clinical picture as well as the anatomical and diagnostic aspects and surgical techniques are underlined. The conclusion is drawn that a preoperative diagnosis is not easy and the importance of enteroclysma and TAC to prove the presence of hernia is underlined.

Adrenal myelolipomas are rare, nonfunctioning, benign neoplasms of the adrenal gland. The authors describe their experience of a case and they report the review of the literature. They illustrate what's etiopathogenetic theories, modern diagnostic technology "of imaging" and different surgical approaches need to be adapted to the excision of the adrenal myelolipomas.

The authors have reported two laparocele cases in the place of insertion of the umbilical trocar, on 156 laparoscopic accesses made by them. Both cases took place at the beginning of their experience when the navel fascial breach had not yet been stitched. The authors made an extensive review of the medical literature and have found out that such complication is rare and to prevent it, it is right to stitch the navel fascial defect, being careful for not englobing the epiploon or an intestinal loop in the suture.

The Authors report 6 cases of Warthin's tumor of the parotid gland recently observed. In all cases the tumor was intraglandular, single, and no noteworthy disorders or symptoms except for a 2 to 5 cms tumefaction were present. At surgery all lesions appeared well-capsulated and the exeresis followed a cleavage plane easily identifiable which enabled the preservation of the residual glandular tissue as well as the surrounding nervous and vascular structures. All the patients, up to now, are free from relapse.

The authors analyze the most current methods for the treatment of ulcerated breast cancer in the elderly. They describe a peculiar case recently observed, characterized by an ulcerative lesion spreading from the hemiclavicle to the foreaxilla including the axillary cavity, causing a large phlebo-lymphaedema, anaesthesia and paresis of the homoteral upper limb. After an initial treatment with tamoxifen a scapulo-humeral disarticulation and a suture of the cutaneous wide defect were performed using a myo-skin graft which included the deltoid muscle. A radiotherapeutic treatment followed by tamoxifen therapy was carried out. No distant metastases and no local relapses were registered in the one year follow up. The Authors on the basis of their experience and according to the review of the Literature suggest that age itself is not a limiting factor to the therapeutic approach of ulcerated breast cancer.

The aim of this study is to evaluate, after laparoscopic (CL) or open (CO) cholecystectomy, the incidence of pulmonary atelectasis and hypoxaemia which are strictly related to the onset of pulmonary complications. Two groups of 20 consecutive patients affected by symptomatic and not complicated gallstone disease were cholecystectomized either using CO or CL. Hypoxaemia was assessed preoperatively and after operation. Postoperative determination was performed at the 4th, 8th, 12th and 24th hour and then every 12 hours until discharge from hospital. A not informed radiologist evaluated atelectasis through two X-rays, preoperatively and postoperatively at the 3rd day. Atelectasis cases were divided in micro, focal, segmental, lobar and of the entire lung. Statistic analysis was performed using the "t" Student test. No mortality or intraoperative complications occurred. The two groups were similar for age, sex, smoker percentage, obesity, preexisting pulmonary dysfunctions and anaesthesiological risk (ASA). Operative time resulted in longer in CL compared to CO patients although in an insignificant way. PO2 value resulted significatively reduced (P < 0.05) at 4th, 8th, 12th and 24th postoperative hour after CO, while subsequent measurements did not show significant differences. There was no evidence of PO2 significative reduction after CL. After operation atelectasis was found in 11 patients (55%) of CL group (P < 0.05) and in 17 patients (85%) of CO group (P < 0.001). Atelectasis observed in the group of 11 CL patients was represented by 7 micro and 4 focal types, while in the CO group 7 micro, 8 focal and 2 segmental types were found. This study suggests that CL alters the pulmonary function less than CO.

The authors report their laparoscopic access technique. It has to be considered a variation of the classical closed technique, with the introduction of the Veress needle and the first trocar directly at the level of the fascia which is kept in traction by two Kochers.

The Authors analysed the complications observed during 156 laparoscopic accesses. In 38 cases following the classic closed technique, two pneumoderma, one pneumoscrotum, one pneumoepiploon and two laparoceles were observed in the umbilical area. In 30 patients the laparascopic access was performed according to the open technique, registering a significant loss of gas during the operation though not compromising it in 4 patients, and two infections of the umbilical incision. In 88 cases the modified closed technique was used and only one infection in the umbilical trocar insertion area was observed. After discussing the incidence, the etiopathogenesis, the diagnosis and the treatment of complications related to the laparoscopic access, the Authors emphasize the fact that in patients with surgical scars near the naval or patients who have already undergone laparascopy, or those with a positive history of affections causing abdominal adherence, the laparoscopic access must be performed using the open technique.

The neuroendocrine carcinoma of the skin (NCS) is an uncommon disease, having been described about 400 cases in world literature. Two cases of NCS in a 52-year-old woman and in a 44-year-old man are reported; their histogenesis is still uncertain. It is advisable a wide cutaneous excision of the neoplasm extending 2-3 cm. over its macroscopic borders, in order to decrease the incidence of local recurrences, reaching 33% in some reports; when regional nodes are involved a lymphadenectomy is recommended. The authors also recommend a prophylactic radiotherapy of locoregional node chains, because of the high radiosensitivity of these tumors.

Thirty-five patients who had undergone gastric resection between two and five years earlier were included in the study. Digestive continuity had been achieved in 18 cases using the BII method, and in 17 using a Roux en Y loop. Vagotomy was not performed in any patient. All patients were assessed using endoscopy and multiple biopsies of the gastric mucous were taken. No postoperative peptic ulcers were observed. Mucous close to the stoma appeared to be hyperemic and edematous in 16 of the patients who underwent gastric resection using the BII method and in 5 of those in whom a Roux en Y loop was used. In BII patients, the histological analysis of endoscopic biopsies revealed mucous alterations in 94.4% of cases, and the most frequent finding was chronic atrophic gastritis; in the Roux en Y patients signs of inflammation were only observed in 58.8% of patients and in the majority of cases it was limited to superficial chronic gastritis.

Twenty-three patients who had undergone surgery for non-neoplastic pathologies of the terminal choledochus were studied using 99mTc Br-IDA. This method is used to study patients operated for PST of CDS because: 1) is not invasive and does not cause allergies; 2) it allows a physiological evaluation of biliary flow to be obtained; 3) it is not influenced by the patient's body structure, by the presence of intestinal gas or costo-chondral calcification; 4) the radiation dose absorbed by the patient is very low; 5) it does not require any special preparation of the patient. Papillosphincterotomy was performed in 16 patients and choledochoduodenostomy in 7 patients. Follow-up varied between a minimum of two and maximum of eight years. The morphology of the biliary tract remained normal in all cases or was only slightly dilated. Captation and excretion time remained within normal values. Marker activity in the duodenum appeared early in all cases. A duodenogastric reflux was only observed in one patient among those undergoing PST, whereas it was observed almost constantly following CDS.

The gastric emptying has been studied with 99Tc labelled in 35 patients followed for 2-8 years after duodenogastric resection. All patients had been undergone a gastric resection of 2/3 of stomach. In 18 had been performed a Billroth II (BII) and in 17 a gastrojejunostomy with a Roux-en-Y anastomosis. The jejunal loop had been carried out about 25-35 cm from the Treitz, the mesenteric margin isolated for 2-3 cm and the jejunojejunostomy performed about 50 cm from the gastrojejunostomy. Nobody complained symptoms from altered gastric emptying. In all patients with Roux-en-Y anastomosis there was an intense radioactivity in the new stoma till the 150th minute, and peristaltic activity was valid and coordinated. In patients with BII there was no radioactivity in the new stoma before the 150th minute, and peristaltic activity was always convulsive and uncoordinated.

Three cases of leiomyosarcomas of the small bowel, two localized in the jejunum and one in the ileum are reported. In the light of reported data, stress is laid on the anatomicopathological aspects and it is pointed out that the symptomatology is not specific and is comparable to that characterising the other neoplasms of the small bowel. The usefulness of the various diagnostic investigations are analysed and it is maintained that surgery plays a primary role in the treatment of such neoformations. It is maintained, finally, that further studies are needed to pinpoint the factors that may be correlated with the prognosis.

A careful survey of the literature on the relationships between pyoderma gangrenosum and Crohn disease is made. The pathogenetical and clinical aspects are analysed and a case, personally observed, is presented.

The role of aminophylline in the re-formation of peritoneal adhesions was considered in 23 rats. Since the adhesions were obtained, the animals were subsequently divided into three groups, the first one containing seven units, the others containing eight animals each. During the four days prior the surgery, allopurinol at the dose of 50 mg/kg/die was added to the regular ground laboratory chow in the animals of the second group; aminophylline at the dose of 40 mg/kg/die was administered four hours and immediately prior the surgery, to the animals of the third group. The adhesions that we observed, were graded and evaluated assigning them a score. At the moment of the lysis of adhesions, we observed the score of 2.71 +/- 1.11 in the first group, 3.12 +/- 1.13 in the second group, and 2.75 +/- 1.03 in the third one. Matching each group one another no statistically significant difference was found. At the end the experiment, we observed a score of 3.71 +/- 0.49 for the adhesions in the first group, 2 +/- 0.75 in the second group, and 3.87 +/- 0.35 in the third one. Matching these scores with those observed at the moment of their lysis, they appeared significantly higher in the animals of the first group (p less than 0.02) and of the third group (p less than 0.05), but they were lower in the second group (p less than 0.05). Such results indicate that the re-formation of peritoneal adhesions following their lysis is constant, that allopurinol decreases the intensity of the process, while aminophylline increases it.
