COVID-19 circuit management: la Rabta experience.

Covid-19 pandemic was associated to fear among patients, doctors and nurses, it was responsible of a work impairment in health structures organisation. All patients were at home, only Covid patients were at hospital. Our country has a quick reaction, we declared the pandemic as a social disease with free management. All hospital had the order to create their own Covid-19 circuit. We report the experience of our hospital in the crisis management with the creation of the circuit, its organisation, the management of the different financial, technical, human, sanitary, psychological and logistical aspects. The great point of this crisis was the fear, stress of caregivers for themselves and their families. The other point for members of Covid Cell was the race against time, the learning of a new job: a manager or a polyvalent chief. The presence of a Covid-19 circuit is necessary for each hospital at the epidemic time but it must be managed by infectious diseases doctors, lung specialists, intensive care givers and emergency room caregivers in collaboration. An enhancement of the structures is necessary at the level of medical wards and beds of intensive care.

[The Caroli's disease. Report of 16 cases]. / La maladie de caroli. A propos de 16 cas.

BACKGROUND: Caroli's disease is a congenital dilatation of the intrahepatic biliary duct. AIM: To analyse and discuss diagnostic and therapeutics difficulties through 16 patients with Caroli's disease. METHODS: Between January 1990 and September 2010, 16 patients underwent surgical procedure for Caroli's disease. Data recorded for each patient included clinical symptoms, biologic findings, previous biliary procedures, and the presenting symptoms. The distribution of the biliary lesions, the surgical procedure and the postoperative outcomes and follow up were detailed. RESULTS: The mean age was 55 years. The mean interval between the first symptoms and diagnosis was 27 months. Five of 16 patients had undergone 12 surgical or endoscopic procedures prior to liver resection. Before the definitive diagnosis, 9 patients presented 15 episodes of acute cholangitis. The diagnosis was established preoperatively in 13 cases, 5 among them underwent previous biliary surgical procedures. The diagnosis was documented peroperatively in 2 cases and postoperatively in 1 case. The distribution of the biliary lesions was monolobar in 13 and bilobar in 3 patients. 13 patients underwent liver resection, in two cases we perfomed biliojejunostomy and the last one had endoscopic sphincterotomy. There was no mortality and the overall postoperative morbidity is about 43%. The follow-up shows that 12 patients still alive with a mean follow up for 53 months, from whom only one patient have intrahépepatic lithiasis. CONCLUSION: The clinical course of Caroli's disease is often complicated by recurrent episodes of angiocholitis and requires iterative surgery. The hepatectomy witch prevented septic complications and degenerescence is possible only in a restricted number of patients.

[Tomodensitometric diagnosis of internal herniation: report of 3 cases]. / Apport de l'enteroscanner dans le diagnostic pre operatoire des hernies internes: a propos de 3 cas.

AIMS: To study the value of the CT scan in the diagnosis of internal herniation and to evaluate its performance comparing its features to preoperative data. CASES: We report 3 cases of patients with internal hernias (two men and one woman whose age is 23, 45 and 60 years) hospitalised in emergency for a small bowel obstruction. There were no previous abdominal surgeries or trauma, The three patients underwent CT scan. Signs of tranmesenteric hernias and hernia through the falciform ligament were diagnosed preoperatively and confirmed at laparotomy. CONCLUSION: The internal hernia is rare cause of small bowel obstruction. The CT scan is an important way to make diagnosis and to choose the surgical strategy.

[Complicated sigmoid tumor: perforated amebiasis]. / Une tumeur sigmoïdienne compliquée: amoebome perforé.

Amoeboma is an inflammatory mass of the colon. It can be an inaugural symptom and thus pose the problem of differential diagnosis with colon cancer. The purpose of this report is to describe the case of a 43-year-old patient who presented with acute abdomen. Physical examination revealed a perforated circumferential mass in the sigmoid colon. Based on a presumptive diagnosis of colonic cancer complicated by perforation, segmental colectomy was performed. Histological examination of the surgical specimen demonstrated colonic amoeboma. The patient was treated using metronidazole. Although rare, amoeboma must be considered in differential diagnosis of cancer of any colonic mass.

Cystic echinococcosis in Tunisia: analysis of hydatid cysts that have been surgically removed from patients.

Echinococcosis/hydatidosis caused by Echinococcus granulosus has a widespread distribution in the human population of Tunisia, particularly in the north-west and centre-west of the country. In a recent study, the morphological features, fertility and viability of hydatid cysts that had been excised from patients in Tunis were explored, and the E. granulosus strain or genotype involved in each case was identified from morphology of the protoscolex hooks and the results of molecular genotyping. The hepatic cysts investigated came from 41 patients [31 women and 10 men, with a mean (S.E.) age of 43.41 (14.25) years] who were treated for cystic echinococcosis, by surgery but rarely with chemotherapy, at the La Rabta Hospital in Tunis, in the 12 months ending in June 2008. Most (56%) of these patients originated from rural areas in endemic governorates. Of the 60 hepatic cysts that were studied, 38.3% were located in the right lobe of the liver and 35.0% each involved both hepatic lobes. Almost a third (31.7%) of the excised cysts were degenerating, with the rest considered viable and either multivesicular (38.3%) or univesicular (30.0%). Almost all (93.3%) of the cysts were categorized as fertile, with a mean protoscolex viability of 21.8%. Protoscolex viability was relatively high in the viable univesicular cysts with a visible cyst wall and in the multivesicular and multiseptate cysts with daughter cysts, and lowest in the cysts that appeared to be solid calcified masses. The observed variation in protoscolex viability with cyst type, in cysts excised from patients before any chemotherapy, supports the cyst classification recommended by the World Health Organization but could also be compatible with the imaging-based 'Gharbi' classification. The results of the molecular genotyping showed that all 23 cysts investigated (which came from 20 of the patients) were caused by E. granulosus of the G1 genotype (also known as the 'sheep' or 'sheep-dog' strain).

[Primary hydatid cyst of the psoas muscle: description of 9 cases in Tunisia and review of the literature]. / Kyste hydatique primitif du psoas: 9 cas tunisiens et revue de la littérature.

The psoas muscle is an uncommon location for hydatid cyst accounting for only 1 to 3% of cases. The purpose of this report is to describe the epidemiologic, clinical, paraclinical, and therapeutic features of primary hydatid cyst of the psoas muscle. A retrospective study conducted in Surgery Department A at the Rabta Hospital in Tunisia compiled a total of 9 cases of primary hydatid cyst of the psoas muscle treated between 1980 and 2006. There were 6 men and 3 women with a mean age of 42.8 years. Symptomatology was nonspecific with pain in 6 cases. Discovery was coincidental in two cases. Clinical examination detected a mass in the presents of an abdominal mass in 7 cases. Radiologic findings (ultrasound and/or CT scan) confirmed diagnosis in 8 cases. In one case a mistaken diagnosis of psoas muscle abscess was made in a patient with an infected hydatid cyst. Serological tests were performed in 4 cases and were positive in 3. All patients underwent surgical treatment. The extraperitoneal approach (Leriche) was used in 7 cases and the transperitoneal approach via median laparotomy in 2. In all cases the surgical procedure consisted of partial cystectomy leaving a part of the pericystic against neurovascular structures. There was no operative mortality. The only postoperative complication was urinary infection in one patient. Mean follow-up was 2.5 years. One local recurrence was observed 4 years after surgical treatment and required reoperation.

A report of 15 cases of small-bowel obstruction secondary to phytobezoars: predisposing factors and diagnostic difficulties.

UNLABELLED: Phytobezoars are a rare cause of acute bowel obstruction. The purpose of this work was to identify the predisposing factors and diagnostic difficulties of this rare entity. MATERIAL AND METHODS: This was a retrospective study including all cases of small-bowel obstruction secondary to phytobezoars observed between April 2001 and August 2007. The diagnosis of bezoars was established by surgical exploration or by computed tomography (CT). RESULTS: During the study period, 375 patients were hospitalized at our institution with a diagnosis of bowel obstruction that, in 15 (4%) cases, was secondary to phytobezoars. The average patient age was 55 years, with a gender ratio of 1.7, favoring men. The predisposing factors were gastroduodenal surgery for peptic ulcer in nine patients, and excessive consumption of prickly pears (cactus figs) in 12. The diagnosis was established by CT scans in three patients, who were successfully treated with gastric aspiration, thereby avoiding surgery. Laparotomy was performed in 12 patients to allow digital fragmentation of the bezoar, which was then washed into the colon. There were no postoperative deaths and morbidity was about 13%. CONCLUSION: An abdominal CT scan should be obtained for patients with small-bowel obstruction. This examination offers a precise diagnosis of bezoars, reducing the number of unnecessary surgical procedures, and helping to guide the approach if surgery is needed.

[Radiologic diagnosis of enterosalpingeal fistula complicating Crohn's disease]. / Diagnostic radiologique d'une fistule entérotubaire compliquant une maladie de Crohn.

Enterosalpingeal fistula is a rare complication of Crohn's disease which is rarely diagnosed preoperatively. We describe a new case of this complication suspected by CT scan and confirmed by hysterosalpingogram and contrast from the ileum. This case is about a 50-year-old woman suffering from ileal Crohn's disease diagnosed two years previously and actually complicated by stenosis and entero-salpingeal fistula. The treatment consisted on resection of the ileocaecal region with salpingectomy. Postoperative course was uneventful.

Kyste hydatique primitif du psoas : 9 cas tunisiens et revue de la litterature

Le muscle psoas est une localisation exceptionnelle du kyste hydatique ne representant que 1 a 3des cas. Le but de ce travail est d'etudier les caracteristiques epidemio- logiques; cliniques; paracliniques et therapeutiques de cette entite. Notre etude est retrospective consecutive portant sur 9 cas de kystes hydatiques primitifs du psoas colliges entre 1980 et 2006 dans le service de chirurgie A de l'Hopital La Rabta. Il s'agissait de 6 hommes et 3 femmes dont l'age moyen etait de 42;8 ans. La symptomatologie etait atypique dominee par les douleurs retrouvees dans 6 cas. La decouverte etait fortuite dans deux cas. L'examen physique retrouvait une masse du flanc dans 7 cas. Le diagnostic etait confirme par la radiologie (echographie et/ou tomodensitometrie) dans 8 cas. Dans 1 cas; le diagnostic d'abces du psoas etait pose a tort chez un patient porteur d'un kyste hydatique infecte. La serologie hydatique pratiquee dans 4 cas etait positive dans 3 cas. Tous les patients etaient operes. La voie d'abord etait extra peritoneale (Leriche) dans 7 cas et transperitoneale a travers une laparotomie mediane dans 2 cas. Le geste a consiste dans tous les cas en une kystectomie partielle laissant une calotte de perikyste contre les elements vasculo-nerveux. La mortalite etait nulle. Un seul patient s'est complique en postoperatoire d'une infection urinaire. Le suivi moyen etait de 2;5 ans. Au cours de la surveillance postoperatoire; une seule recidive locale etait diagnostiquee a 4 ans postoperatoire ayant necessite une nouvelle intervention

[Subcutaneous hydatid cyst. Case report of an exceptional location]. / Kyste hydatique sous-cutané: à propos d'une localisation exceptionnelle.

Primary subcutaneous cyst hydatid disease is an exceptional entity. We report a new case involving a 70-year-old woman hospitalized for a subcutaneous mass in the hypogastric area with no local inflammatory signs. Radiological examination was consistent with a partially calcified subcutaneous cyst in the hypogastric area. Complete surgical resection of the mass was performed with uneventful postoperative recovery. Histopathological examination of the surgical specimen demonstrated multivesicular hydatid cyst.

[Unopened colostomy in colorectal surgery: a renewal interest?]. / La colostomie à ouverture potentielle en chirurgie colorectale: un regain d'intérêt?

INTRODUCTION: Anastomotic leak or disruption is a grave complication of colorectal surgery. Protection of an at-risk anastomosis by an upstream open diverting colostomy (OC) reduces this gravity. An unopened upstream loop colostomy is a surgical alternative which may diminish the unpleasant consequences of an open colostomy while maintaining the option of diversion in case of need. The aim of this study is to report the results of this approach and to define its indications. MATERIAL AND METHODS: [corrected] We report a retrospective series of 34 cases of unopened diverting loop colostomy to protect an at-risk colorectal anastomosis. Indications for this procedure were stool-laden bowel (59%), low serum albumin (11.5%), local inflammation (11.5%), and very low placed anastomosis (17.5%). RESULTS: The loop colostomy was eventually opened after surgery in six cases because of anastomotic leakage diagnosed clinically and/or detected by water soluble contrast opacification which was performed routinely on the sixth post-operative day. In all six cases, there was no need for an urgent surgical intervention. In 28 cases, the anastomosis healed without complication and the exteriorized loop was returned to the abdominal cavity seven days after the initial surgery. This was a short, simple procedure with an average operating time of ten minutes. Average hospital stay after returning the unopened colostomy to the abdomen was two days. CONCLUSION: Unopened loop colostomy offers the advantages of protection of a colorectal anastomosis without proper morbidity or mortality, shorter hospitalization, and improved psychological comfort for the patient. It's principal indication is to minimize the risks related to leakage from an at-risk colorectal anastomosis.

[Gastric amyloidosis mimicking malignancy. A case report]. / Amylose gastrique simulant une linite plastique. A propos d'une observation rare.

Amyloidosis is an abnormal extracellular deposition of insoluble proteins, which is associated with an involvement of the gastrointestinal tract in 50 to 70% of cases. In primary amyloidosis (light chain amyloidosis), localized gastric involvement is a rare finding which can mimic malignancy. We report the case of a 56-year-old man, admitted with upper digestive outlet obstruction. Linitis plastica with lymph node involvement was suspected by gastroscopy, barium meal and endoscopic ultrasonography but was not confirmed by gastric biopsies. The patient was treated with total gastrectomy with lymph node dissection. Pathological examination demonstrated gastric and lymph nodes amyloidosis and no malignant tumor was found. The patient died 9 months later from cardiac failure due to amyloidosis.

[Intraductal papillary mucinous tumor of the pancreas degenerated and fistulisated in the stomach, the duodenum and colon]. / Tumeur intracanalaire papillaire mucineuse du pancréas dégénérée et fistulisée dans l'estomac, le duodénum, et le côlon.

We report a case of intraductal papillary mucinous tumor of the pancreas (IPMT) degenerated and fistulized into the stomach, the duodenum and the colon. Diagnoses of malignancy and fistulization were proven preoperatively. Pancreaticoduodenectomy extended to the body was performed. Pathological examination revealed a malignant IPMT with an invasive component. Of the 3 fistulizations tracts, both gastric and duodenal ones were malignant. To our knowledge, this is the first reported case of IPMT with colonic fistulization. Twelve months later, the patient is alive without signs of recurrence.

[Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas. A case report]. / Le carcinome indifférencié avec cellules géantes de type ostéoclastique du pancréas. A propos d'une nouvelle observation.

Undifferentiated carcinoma with osteoclast-like giant cells is a rare pancreatic neoplasm, with a possible cystic pattern, includes an adenocarcinoma component and giant cell mimicking osteoclastic bone tumor. We report the case of a 72-year woman admitted for jaundice and epigastric pain. Abdominal ultrasound and computed tomography scan revealed a 6 x 5 cm cystic and solid tumor of the pancreatic head with both bile duct and pancreatic duct dilatation. A pancreaticoduodenectomy was performed and pathologic examination revealed an undifferentiated carcinoma with osteoclast-like giant cells of the pancreatic head. The patient was alive and disease-free with a 18-month follow-up.

[Ménétrier disease associated with a gastric adenocarcinoma. Apropos of 2 cases]. / Maladie de Ménétrier associée a un adénocarcinome gastrique. A propos de deux cas.

Two new cases of Menetrier's disease with gastric adenocarcinoma in two men aged 62 and 81 years, respectively, are reported. In both cases, the diagnosis was established by histologic examination of the operative specimen. Emphasis is placed on diagnostic difficulties and on the risk of malignant transformation of Menetrier's disease, which should be viewed as a precancerous gastric lesion.
