Laparoscopic cholecystectomy decreases extra surgical site morbidity compared with open cholecystectomy: A propensity matched analysis.

Background: The ideal way to show treatment effectiveness is through randomized controlled trials the 'gold standard' in evidence-based surgery. Indeed, not all surgical studies can be designed as randomized trials, sometimes for ethical and otherwise, for practical reasons. This article aimed to compare laparoscopic cholecystectomy to open cholecystectomy, according to data from an administrative database, managed by a propensity matched analysis.

[Spinal anesthesia versus general anesthesia for inguinal hernia repair: propensity score analysis].

Background: Administrative database, used previously for control of cost, patient flow and invoicing, offer to researchers a large sample of patients representative of population providing interesting information's in the field of descriptive and analytic epidemiology with less cost.

Aim: To compare spinal to general anesthesia for inguinal hernia repair concerning a population extracted from administrative database after propensity matched analysis.

Methods: Prospective study concerning 4690 hospitalizations in Department B of General Surgery of Charles Nicolle hospital during a period of 18 months, between June 1st, 2008 and December 31st, 2009.

[Assessment of care quality in department of general surgery : usefulness of administrative database].

Background: Administrative database, used previously for control of cost, patient flow and invoicing, offer to researchers a large sample of patients representative of population providing interesting informations in the field of descriptive and analytic epidemiology with less cost.

Aim: To assess the usefulness of administrative database for quality of care and research.

Synchronous double cancer of the common bile duct.

Synchronous double cancer of the common bile duct is exceptional and only one reported case was found in the literature. We report a case in which the diagnosis of the double tumor was missed by computed tomography scan, magnetic resonance imaging, and endoscopic ultrasonography. The diagnosis of the distal tumor was made only during surgery.

[Intraductal papillary mucinous tumor of the pancreas mimicking pancreatic pseudocyst].

Background: Most of pancreatic cysts are in fact pseudocysts. Only 10 to 20% are real cystic tumors. Intraductal papillary mucinous tumors of the pancreas represent nearly 15% of them.

An aggressive course of de novo ulcerative colitis after renal transplantation: colonic adenocarcinoma with choriocarcinomatous differentiation.

Aim: A rare case of colonic carcinoma arising in de novo ulcerative colitis after renal transplantation in a 42-year-old woman is reported.

Case: Clinically, the patient presented ulcerative colitis 8 years after renal transplantation, developed colonic cancer with liver metastasis 2 years later and died one month post operatively. Histologically, the removed tumor was composed of two distinctive elements consisting of adenocarcinoma and choriocarcinoma.

[Hydatid cysts of the pancreas, report of two cases].

Background: Hydatid cyst of the pancreas is a rare affection with a frequency less than one percent of the various sites of hydatid disease.

Aim: We report two cases of hydatid cyst of the pancreas. CASE 1: A 49 year old woman with a history of laparotomy for liver and peritoneal hydatid cyst was admitted with recurrent liver and peritoneal hydatid disease associated with a head pancreatic cyst of 3 cm in size.

[Myofibroblastic tumor of the great omentum].

Background: Myofibroblastic tumors are a spindle cell lesion of indeterminate malignant potential. Abdominal location was rare.

Aim: We report a case of an unusual location of myofibroblastic tumors in the great omuntum.

Squamous cell carcinoma arising in Verneuil's disease.

Background: Verneuil's disease or hidradenitis suppurativa is a chronic suppurative, and cicatricial inflammatory disease, mainly affecting apocrine-bearing area of the skin. Squamous cell carcinoma is an uncommon but a frightening complication of hidradenitis suppurativa.

Aim: To report a new case of squamous cell carcinoma arising in Verneuil's disease.

[Prognostic study of liver abscess].

The objective of this work is to study factors of prognostic of mortality of abscesses of the liver. We have treated between 1990 and 2000 in our service, 38 patient for abscess of the liver. The symptoms are dominated by the pain of the right hypochondria (37 cases) and the fever (34 cases).

[Abdomino-pelvic actinomycosis: a case report].

The actinomycosis is a chronic suppurative granulomatosis disease. It is owed to a bacillus gram positive; actinomycès israelli. The cervical and thoracic localizations are most frequent.
