[Acute occlusion with fever in a Tunisian woman]. / Syndrome occlusif fébrite aigu chez une tunisienne.

The purpose of this report is to describe a case of idiopathic segmental infarction of the great omentum, in a Tunisian woman, who presented with acute right hypchondrial pain simulating cholecystitis. Abdominal CT scan is the modality of choice. If symptoms resist medical treatment or complications occur, laparoscopic excision is the best therapeutic technique.

[Appendicular cystadenocarcinoma with cutaneous fistula]. / Cystadénocarcinome appendiculaire fistulisé à la peau.

BACKGROUND: Cutaneous metastasis of colorectal cancer is rare. We report a case of fistular lesions of the buttocks revealing a mixed tumour of the appendix involving mucinous cystadenocarcinoma and carcinoid tumour. CASE REPORT: A 67-year-old woman was admitted for four skin fistulae of the right buttock present for 6 years. Histological examination of skin biopsy specimens identified infiltration of the dermis by metastatic mucinous adenocarcinoma while colonoscopy showed a caecal tumour measuring 4 cm. Surgical excision was performed involving right hemicolectomy, evacuation of retroperitoneal mucin collection and excision of fistulae. Histopathological examination of surgical specimen confirmed mixed tumour consisting of perforated mucinous cystadenocarcinoma and carcinoid tumour of the appendix. Recurrence of the fistular lesions was seen. The patient was hospitalized several times for surgical drainage of mucin. She died one year later. DISCUSSION: Cutaneous metastasis of colorectal cancer is an uncommon event that usually occurs after identification of the primary tumour and generally indicates advanced-stage disease and an ominous prognosis. This case is particular and underlines the need to rule out a metastatic origin of cutaneous fistulae, even in patients otherwise apparently in good health.

[Intrauterine device and pelvic tumor: two case reports of pelvic actinomycosis with pseudotumor from tropical zones]. / Dispositif intra-utérin et tumeur pelvienne: 2 observations sous les tropiques d'actinomycose pelvienne pseudotumorale.

Pelvic actinomycosis is a rare chronic disease caused by actinomycete species. The pseudotumorous form is the most common and often leads to misdiagnosis. The purpose of this report is to describe two cases of pelvic actinomycosis involving women with a history of intrauterine contraceptive device (IUD) use. Diagnosis was based on pelvic mass and the findings of surgery undertaken for suspicion of an advanced ovarian tumor with hepatic metastasis in one case and for a tumor of the right ovary in the other case. Diagnosis was confirmed by histological examination of a biopsy specimen in the first case and of the surgical specimen (right ovariectomy) in the second case. Long-term antibiotic therapy was effective in both patients. Based on these two cases and review of the literature, discussion focuses on diagnostic pitfalls, natural course, and therapeutic options for this particular infection.

[Intestinal perforation in a Tunisian woman: peritonitis due to a fishbone]. / Un coup de poignard abdominal chez un tunisien: péritonite par arête de poisson.

Diagnosis of foreign body perforation of the gastrointestinal tract can be difficult. The purpose of this report is to describe a case of acute peritonitis after perforation of the ileum by a fish bone that was detected by computed tomography.

[Extrahepatic cholestasis secondary to Castleman's disease]. / Cholestase extrahépatique secondaire à une maladie de Castleman.

Castleman's disease is a rare lymphoproliferative disorder of unknown etiology with different clinical manifestations. A 76-year-old man presented with pruritus and jaundice, a cholestasis and an increase of acute phase reactants. Peroperative investigations evidenced a 3-cm lymphadenopathy that compressed the biliary duct. Diagnosis of multicentric Castleman's disease was confirmed by the histologic examination of the lymphadenopathy. HIV testing was negative. Corticosteroid therapy was started and partially controlled the disease.

[Esophageal leiomyomatosis revealing an Alport syndrome]. / Léiomyomatose oesophagienne révélatrice d'un syndrome d'Alport.

Alport syndrome is a rare progressive hematuric nephropathy associated with sensorineural deafness. Leiomyomatosis associated with Alport syndrome is quite rare. We report a particular case of Alport syndrome which was diagnosed in the setting of an oesophageal leiomyomatosis. Alport syndrome and leiomyomatosis are caused by mutation of the genes encoding for the alpha chain of type IV collagen. In view of the important clinical and genetic implications, renal function and urinary status should be controlled in any patient with oesophageal leiomyomatosis.

[The solid pseudopapillary tumor of pancreas: two cases and literature review]. / Tumeurs pseudopapillaires et solides du pancréas: deux observations et revue de la littérature.

Solid pseudopapillary tumor (SPT) of the pancreas is a rare exocrine pancreatic tumor behaving in a low-grade fashion, with limited local invasion risk and a rare metastatic evolution. We report SPT in two young females, revealed by abdominal pain and an epigastric mass. The diagnosis of a cystic tumor was based on abdominal ultrasound and CT data in the first case and on MRI in the second. A distal pancreatectomy and splenectomy were successfully performed in the first case and a central pancreatectomy in the second. Histological study confirmed the diagnosis of SPT of the pancreas.

[Laparoscopic treatment of perforated duodenal ulcer: 84 cases in Tunisia]. / Traitement laparoscopique des ulcères duodénaux perforés: 84 cas en Tunisie.

INTRODUCTION: The purpose of this study was to evaluate the feasibility, efficacy and safety of the laporascopic treatment of perforated duodenal ulcer. METHODS: This retrospective study included patients who underwent laparoscopic treatment of perforated duodenal ulcer during the seven-year period from 2001 to 2007. The procedure included direct suture of the perforated ulcer followed by peritoneal lavage. All patients received medical treatment including Helicobacter pylori eradication and proton pump inhibitor therapy. RESULTS: A total of 84 patients underwent laparoscopic surgery for perforated duodenal ulcer during the study period. There were 81 men and 3 women with a mean age of 28 years. Laparoscopic examination confirmed diagnosis of perforated duodenal ulcer in all cases. Direct suture of the ulcer was successful in 72 cases. In the remaining 12 cases conversion to open surgery was necessary due to difficulty in achieving peritoneal lavage in 6 cases, ulcer size and edge friability in 5, and septic shock in one. The mean duration of the procedure was 95 minutes (range, 60 to 180 minutes). The mean postoperative complication rate was 15.4%. Complications included peritonintis in one case and digestive fistula in one. There were no postoperative deaths. All patients were re-examined after 25 months. Two patients presented recurrences after the laparoscopic treatment and required tri-therapy. CONCLUSION: Laparoscopic suture of perforated duodenal ulcer is safe and effective. It avoids the need for laparotomy that is associated with a risk for septic and parietal complications. Since medical treatment is effective for ulcerous disease, there are currently no indications for radical treatment.

[Severe rectal bleeding in an Tunisian woman: colonic tuberculosis mimicking a tumor]. / Une rectorragie sévère sous les tropiques.

Since colonic tuberculosis is uncommon and its bifocal pseudo-tumor form is exceptional, differential diagnosis with the colonic cancer is exceedingly difficult. The purpose of this report is to describe a case of primary colonic tuberculosis in two separate locations discovered in a patient presenting with persistent massive hematochezia. A 69-year-old woman was examined for hematochezia, abdominal pain and recent weight loss. Colonoscopy revealed the presence of two ulcerated tumor-like lesions in right colon. One of these lesions caused significant stenosis. Histological examination of biopsy specimens was inconclusive. Colonic tumor with bleeding was considered as the most likely diagnosis. Surgical exploration demonstrated one tumor in the cecum and another in the ascending colon. Right hemicolectomy was performed. Histological examination of the surgical specimen demonstrated a granulomatous reaction pattern with caseous necrosis. Conventional antituberculosis treatment led to clinical improvement.

[Two pelvic tumors which should not be operated, lymphoma of Burkitt and actinomycosis]. / Le lymphome de Burkitt et l'actinomycose, deux tumeurs pelviennes qu'il ne faut pas opérer.

The treatment of the pelvic tumors depends of their histological nature. Some of them require only one medical treatment without recourse to surgery. We report two rare cases of pelvic tumors occurring in young adults. For the first case, actinomycosic nature was related to the histological study of the surgical biopsies. Concerning the second case, the lymphatic nature of a tumor of the low rectum was retained on the immunohistochimic study of the endoscopic biopsies. The evolution was uneventful in the two cases after a medical treatment containing penicillin G or a chemotherapy. We discuss at the time of these two observations the diagnostic difficulties and the therapeutic methods of these rare affections.

[Frantz's tumor: anatomoclinical study of six Tunisian cases]. / La tumeur de Frantz: etude anatomoclinique de six cas tunisiens.

Solid and pseudopapillary tumour (Frantz's tumour) is a rare low-grade neoplasm of the pancreas. We report six new cases. Our objective is to specify clinical and pathological characteristics of this rare neoplasm and to discuss its histogenesis. A retrospective review was considered on six Tunisan patients who had solid and pseudopapillary tumor of the pancreas. A review of medical registries and morphological analysis with immunohistochemical study were carried out in all cases. Four patients were female and two patients were male with a median age of 27,5 years (range: 14 - 68 years). Abdominal pain was the most common initial symptoms (5 cases/6). Abdominal computed tomography and/or ultrasonography was used in all the cases. The tumour was in the tail of the pancreas in 4 patients and in the body of the pancreas in one patient; one tumor involved all the pancreas. The median diameter of the tumour was 16,8 cm (range: 8 - 35 cm). Three tumours had an extrapancreatic extension. All patients underwent surgical resection. No adjuvant therapy was recommended. The mean follow up period was 24 months (range: 5 - 78 months). Only one patient died during the surgery. Except for this patient, none experienced tumor recurrence or tumor-related mortality during the follow up period. Solid and pseudopapillary tumour of the pancreas is an uncommon neoplasm which shows distinct clinicopathologically characteristics. Despite diverse studies, its histogenesis remains undetermined. This tumor should be distinguished from other pancreatic neoplasms because its prognosis is excellent after surgical resection.

[Pyogenic abscess of the breast: clinical and therapeutic aspects]. / Abcès du sein à pyogènes: aspects cliniques et thérapeutiques.

OBJECTIVE: The goal of this retrospective work was to study the clinical aspects and the principles of management of the abscess of the breast in order to determine a convenient and recent therapeutic attitude. PATIENTS AND METHODS: Our retrospective survey concerns 114 cases of breast abscess collected in a surgery department over a period of 14 years, from 1990 to 2003. All patients have been operated and the diagnosis confirmed through the operation. The puerperal abscesses have been noted in 31 cases. RESULTS: One hundred and four women and ten men were concerned, with a sex-ratio of 0.1. The medium age was 33 years old for the women and 42 years for the men. The diagnosis was based on the clinical criteria, confirmed by the ultrasonography in 11 cases out of 16 and by the mammary puncture in 15 cases out of 22. Two non-puerperal abscesses have revealed an infiltrating canal carcinoma. The Staphylococcus aureus was the germ the most frequently met, concerning 8 cases out of 16. The surgical biopsies carried out in 52 cases revealed a fibrocystic mastopathy in six cases, a canalar ectasia in two cases and an infiltrating canalar carcinoma in two cases. The surgical treatment, performed in any case, was associated to an anti-staphylococcus antibiotherapy. The recurrence of the abscess has been observed in four cases. DISCUSSION AND CONCLUSION: The frequency of pyogenic abscess of the breast, particularly the puerperal abscesses, has considerably decreased. The non-puerperal abscesses often pose a differential diagnosis problem with the very aggressive inflammatory cancers. The percutaneous ultrasonography guided drainage must be proposed in first intention to treat the abscesses of the breast. However, surgical treatment is still valid with an abscess either relapsing or chronic, or else the failure of the non-operative processes.

[Internal trans-Oddi's sphincter fistula drainage of hydatid cysts communicating with the bile ducts]. / Drainage interne trans-fistulo-oddien des kystes hydatiques ouverts dans les voies biliaires.

OBJECTIVE: The purpose of this study was to examine the contribution of internal trans-fistulary drainage without opening the cystic cavity for the treatment of hydatic cyst of the liver. PATIENTS AND METHODS: Between 1985 and 1990, 14 patients with hydatid cyst of the liver communicating with the bile duct were treated by internal trans-fistulary drainage without opening the hydatic cavity. Choledocoscopy demonstrated good bile flow without a remaining cystic fragment in all cases. The residual cavity was drained via an external drain in the common bile duct. A second hydatic cyst of the liver was also treated in 4 patients. RESULTS: Internal trans-fistulary drainage was achieved easily. There were two treatment-related postoperative complications: bilary leakage in one patient and infection of the residual cavity leading to septicemia and death in another. CONCLUSION: Internal trans-fistulary drainage without opening the hydatic cavity is indicated for central hydatic cyst of the liver measuring less than 15 cm with a flexible pericyst and a large biliocystic fistula measuring more than 5 mm. Peroperative choledochoscopy of the hydatic cavity is necessary.

[Kidney contusions and traffic accidents. Apropos of the Tunisian experience]. / Contusion rénale et accidents de la voie publique. A propos d'une expérience tunisienne.

The authors report a retrospective series of 45 cases of blunt renal trauma from a total of 685 cases of blunt abdominal trauma observed between 1989-1993. This multicentre trial was designed to illustrate the severity of this type of trauma and to place it in the context of road accidents in Tunisia.

[Hydatic cyst of the kidney. Eighteen cases]. / Le kyste hydatique du rein. A propos de 18 cas.

18 patients with 18 hydatid cyst of kidney, underwent surgical intervention from 1982 to 1994. There were 6 men in the series and 12 women who ranged in age from 7 to 65 years (mean 38 years). Flank pain was the chief complaint (55%). Abdominal mass was detected on physical examination in 38% of cases. Ultrasonographic examination, performed in all cases, made a correct diagnosis in 13 patients (72%). Excretory urogram (IVP), performed in 9 patients, showed signs of benign tumor process. All patients were operated on: the procedures performed included 12 resection of "protruding dome", 1 total nephrectomy, 3 partial pericystectomy, 2 total pericystectomy, 1 total nephrectomy. In postoperative course, there was one death (5.5%) and morbidity was 11%. We conclude that hydatid cyst of kidney still rare but possible in endemic areas; its treatment, usually surgical, still difficult because it should avoid recurrence of hydatic disease without sacrifice of the kidney.

[Internal abdominal hernias. Report of 8 cases]. / Les hernies internes de l'abdomen. A propos de 8 cas.

Internal abdominal hernias are rare. There unexpected discovery at laparotomy confront the surgeon at anatomic diagnosis problem. 8 cases of internal abdominal hernias were observed between 1989 and 1998: transmesenteric in 3 cases, mesosigmoidal in 2 cases, paraduodenal in 2 cases, needing intestinal resection. Hernia foramen were sutured in all of cases without hernial sac's resection. The results of the present series were excellent without recurrence. Literature review show that internal hernias were responsible of complex anatomic and surgical presentations. The primary task of the surgeon is not so much to establish the diagnosis of internal hernia but intestinal occlusion to decide at time urgent operation.

[Fatal postoperative crisis in acute hereditary porphyria]. / Crise post-operatoire fatale d'une porphyrie aiguë héréditaire.

The acute porphyria is an autosomal dominant disorder of the héme biosynthesis enzyme. The aim of this work is to determin a diagnostic step in order to anticipate porphyric crises. We report the observation of a child which was hospitalized in the pédiatric service three years ago for peripheric arthralgies and myalgies where the diagnosis of an acute porphyria was not posed. He wase admitted in our service for appendicitis, he was operated, the anesthesie was carried out by the thiopenthal and the succinylcholine. At the first post-operative day, a respiratory insufficiency was the cause of death. The rate of coproporphyrines and of uroporphyrines in the urine had confirmed the diagnosis of acute porphyria. The positive diagnostic of acute porphyria is difficult, the association of abdominal, psychological and neurologic signs must suggest the diagnostic, all the more, if the urines have a dark colour. The presence of uroporphyrines and coproporphyrines and certain precursors in the urines or in the high-rated stools confirm the diagnostic. The family survey and dosage of porphyric compounds in the sickness-bearing patient's family members allow to reveal certain asymptomatic forms of the heriditary acute porphyria, it is caused by certain products used in neuropsychiatry, in aneasthesic or in certain circunstances, such as, the infection or the trauma. The treatment of the acute porphyria is an emergency wich requires the transfert of the patient to a unit of intensive care.

[Sensitivity, specificity and prognostic value of CEA in colorectal cancer: results of a Tunisian series and literature review]. / Sensibilite, specificite et valeur pronostique de l'ace dans le cancer du colon rectum: resultats d'une série Tunisienne et revue de la littérature.

In order to determine the sensitivity of CEA in the diagnosis of colo-rectal carcinoma, we studied a series of 48 patients with colo-rectal carcinoma (1992-1996). The sensitivity was at 52% with a reference value of 5 ng/ml and 68.7% for a reference value of 2.5 ng/ml. With a reference value of 5 ng/ml, the sensitivity of CEA was at 37% only for patients with colo-rectal carcinoma at Dukes B stage, 66.6% for patients at stage C and 75% for patients at stage D. The dosage of CEA was carried out with a sandwich immunoenzymatic technique in tube. There is no statistic significant correlation between the pre-operative rate of CEA and the localisation of the tumor and its histologic type; in contrast, it was significantly correlated with the ganglionnary metastasis. A significant relationship between the pre-operative rate of CEA and the Dukes stage was found for a reference value of 10 ng/ml but not for a reference value of 5 ng/ml. We calculated the specificity of the CEA for the cancers of colon and rectum which was at 76.98% with a reference value of 5 ng/ml and 86% with a reference value of 10 ng/ml.

[A long survival after the treatment of a squamous cell carcinoma of the gallbladder]. / Une longue survie après traitement d'un carcinome épidermoïde de la vésicule biliaire.

We report the case of a long survival after the treatment of a squamous cell carcinoma of the gallbladder. The patient is a 58-year-old man, who was treated by cholecystectomy, followed by postoperative radiotherapy of the tumour bed at a dose of 45Gy, combined with 5-fluoro-uracil chemotherapy. After 18 years, the patient is alive in complete remission. The end point of this work was to study the clinical and therapeutic characteristics of squamous cell carcinoma of the gallbladder and its prognosis through this case and a review of literature.
