    ABSTRACT: Gastric volvulus is a rare but potentially life-threatening clinical entity due to possible gastric necrosis. A wandering spleen may also be associated with gastric volvulus. Patients presenting with the triad epigastralgia, vomiting followed by retching, and difficulty or inability to pass a nasogastric tube into the stomach are likely to have gastric volvulus. The operating surgeon should include this rare entity in the differential diagnosis when dealing with a patient with such a clinical profile. Herein, we present a case of gastric volvulus associated with a wandering spleen in a 28-year-old Caucasian woman and we provide a brief review of the literature on this issue.

    ABSTRACT: Women with HPV related pathology of the lower genital tract are at higher risk for AIN and anal cancer than the general population. A strategy to identify anal disease in these women has not been formulated. The aim of this study is to examine the feasibility of HPV related biomarker testing on anal smears, to identify the risk factors for anal HPV positivity and to provide information of the clinical implications of anal HPV infection in this population. In women referred for colposcopy because of HPV related pathology of the lower genital tract (cervical cancer, CIN, VIN, warts) a detailed questionnaire, an anal smear and a cervical smear were taken. On each sample morphological cytology, flow cytometric evaluation of E6&7 mRNA, and HPV DNA detection and typing were performed. Women with a positive anal result were referred for high resolution anoscopy. So far 235 women have been included (mean age 34.3). HPV DNA, high-risk HPV DNA, high-risk mRNA was detected in 45%, 31% and 8% of the anal smears and in 56%, 39% and 25% of the cervical smears respectively. Absolute or partial concordance of the types between the cervix and the anus was seen in 74%. Positivity for mRNA was significantly lower in the anus than the cervix (8% vs 25%). Logistic regression analysis revealed risk factors for the presence of anal HPV DNA (>3 lifetime sexual partners and presence of cervical HPV DNA), hr HPV DNA (presence of cervical hr HPV DNA), and hr mRNA (presence of cervical hr mRNA). Twelve months after LLETZ 53% of women were cervical HPV negative, but 25% of those were still HPV positive in the anus. HPV infection of the anus is common in this group and is interlinked with the cervical infection. Anal HPV E6&7 mRNA expression is less common than in the cervix. Possible clinical implications of anal infection could be the development of AIN and recurrence of CIN after treatment due to cervical reinfection from the anal reservoir. The use of HPV biomarkers is feasible in anal smears, although especially DNA testing as triage method for referral to anoscopy is probably inappropriate due to high positivity rate.

    ABSTRACT: Fournier gangrene is a very rare and a rapidly progressing, polymicrobial necrotizing faciitis or myonecrosis of the perineal, perianal and genital regions, with a high mortality rate. Infection is associated with superficial traum, urological and colorectal diseases and operations. The most commonly found bacteria are Escherichia coli followed by Bacteroides and streptococcal species. Diabetes mellitus, alcoholism, and immunosuppression are perpetuating co-factors. Fournier's gangrene complicating inflammatory bowel disease has been reported in three patients so far, two with Crohn's disease. A 78-year-old man diagnosed with ulcerative pancolitis was referred for fever, and painful perianal and scrotal swelling after perianal surgery for a horseshoe-type perianal abscess. Since bowel disease diagnosis, patient was on mesalazine and achieved long-term remission. Perianal abscess occurred suddenly one week before perianal surgery without any evidence of pre-existing fistula or other abnormalities. Physical examination showed extensive edema and crepitus of perineum and genitalia and patient had symptoms of significant toxicity. The diagnosis of Fournier's gangrene was made and patient underwent emergency surgery with extensive surgical debridement of the scrotal and perianal area and Hartman procedure with a diverting colostomy. In addition, patient started on therapy with mesalazine 3gr, methylprednisolone 16 mg, parenteral nutrition and broad spectrum of antibiotics. Two days after the first operation the patient needed a second operation for perianal debridement. On the fourth day, blood cultures showed E. coli. Patient had an uneventful recovery and was discharged after 34 days of hospitalization. On follow up, disease review is scheduled and colostomy closure is planned.

    ABSTRACT: tract and on their immunophenotype as specific c-kit expressing and kit signaling driven mesenchymal tumours, most of which have kit-activating mutations 2,3 . We describe herein an unusual case of GIST, due to the combination of morphological and pathological features. Case report A 76 year old woman was initially admitted to our hos-pital for investigation of anemia and of an intra-abdom-inal tumor, which had been identified on physical exam-ination. On admission the patient was well nourished. The pre-senting symptoms were weakness and constipation for Gastrointestinal stromal tumor of the gastric serosa protruding to the greater omentum. Report of a giant tumor with a rare histological pattern. We report an unusual case of a 76 year old woman admitted to our hospital for investigation of anemia and palpable epigastric mass. Intraoperatively a huge (19 cm), well defined tumor was found adhering to the stomach wall, protrud-ing into the greater omentum and compressing the transverse colon. A tumorectomy was performed and the greater omen-tum was removed due to its close relation. Pathology revealed a high risk Gastrointestinal Stromal tumor of the gastric serosa. Histologically the tumor was of mixed type (spindle and epitheliod cells) with hemangiopericytomatoid pattern peripherically, variably myxoid stroma, central necrosis and cytologic pleomorphism. On immunohistochemical examina-tion there was a consistent positivity for c-kit (CD-117) and CD-34, but without myogenic or neural differentiation. We consider this case unusual because of its huge size, its gastric serosal location and its extremely rare histological pat-tern.

    ABSTRACT: For 5 years (January 1998 to November 2002) our department has applied the Marlex Mesh Perfix Plug hernioplasty. This article demonstrates the experience gained in operative and postoperative aspects, costs, and outcome along with the results of a follow-up analysis. Altogether, 801 patients (749 males, 52 females) were operated on Sixty-four males had bilateral groin hernias, so the total number of hernioplasties amounted to 865. A total of 19 hernias were recurrent, 297 were direct, 545 were indirect or scrotal (or both) 21 were femoral, and 2 were Spigelian. Fifty-three operations were performed on an emergency basis. Preoperative routine use of antibiotics was minimized throughout the years. Operating time fluctuated from 20 to 25 min (30-40 minutes for recurrent hernias), and the postoperative hospital stay was 28 hours (6-72) hours. The complication rate was 5% and the recurrence rate less than 1%. Early patient mobilization and return to everyday activities (1-2 weeks) was encouraged. The follow-up of 95% of the patient population lasted 12 to 60 months and was performed at 1 week, 1 month, 1 year, and yearly thereafter. The technique demonstrates less overall postoperative pain, discomfort, and complications combined with a remarkably low recurrence rate. The rapid rehabilitation with great patient comfort and decreased operating room time, resulting in lower financial costs, have led us nowadays to repair all types of inguinal hernias, femoral and recurrent ones, using this technique.

    ABSTRACT: The aim of this study was to evaluate the effectiveness of botulinum toxin for the treatment of uncomplicated dorsal chronic idiopathic anal fissure. Forty-five patients who reported post defecatory anal pain since two months or more were given a total of 20U botulinum toxin in the anal sphincter apparatus on both sides as well as below the anal fissure. Thirty-seven patients received a second session of 25U botulinum toxin injection. Thirty-five patients (78%) presented completely healed anal fissure, while ten needed lateral internal sphincterotomy. All patients were followed up for 8-36 months. Two patients relapsed. Local injection of botulinum toxin is a new and safe treatment; however, two sessions of injections are necessary to be effective and long-term follow-up to assess the recurrence rate of fissure is needed to evaluate further this method of treatment. Partial internal lateral sphincterotomy is no more the treatment of choice for chronic anal fissure.
