Triorchidism diagnosed during a routine hernia repair: A case report and literature review.

Introduction: Triorchidism is a rare anomaly whose management raised considerable discussion. Several factors must be considered, including the patient's age, the testes location, their functional status, and the accessibility and compliance for follow-up. We present a case of triorchidism diagnosed incidentally during a routine hernioplasty procedure, serving educational and informative purposes.

Gastric metastasis and peritoneal carcinosis revealing primary breast cancer: an unusual presentation.

Breast cancer is the most frequent cancer among women. Gastrointestinal tract metastases are uncommon and might be misidentified as primary carcinoma.A noteworthy case-study involved 53-year-old-woman complaining from epigastric pain, ascites and overall health decline.

Biosimilar versus branded enoxaparin to prevent postoperative venous thromboembolism after surgery for digestive tract cancer: Randomized trial.

Cancer and/or major surgery are two factors that predispose to post-operative thrombosis. The annual incidence of venous thromboembolic disease (VTED) in cancer patients was estimated at 0.5%-20%.

Predictive factor of recurrence after curative resection for stage I-II colon cancer.

Background: Colon cancer has become a common malignant neoplasm in Tunisia. Patients with negative lymph node have a 5 years recurrence rate of 21.1%.

Self-directed learning digital tool versus tutorials under the guidance of an educator: Randomized trial.

Introduction: Self-directed learning digital tool aims to enable students to acquire skills in an autonomous way. The aim of this work was to compare a self-directed learning digital tool in non-traumatic abdominal emergencies with tutorials under the guidance of the educator in two parallel groups of second-year of second-cycle of medical students selected by means of a draw.

Methods: We performed a controlled trial with draw comparing the self-directed learning digital tool and tutorials under the guidance of a teacher.

Morbidity and mortality of infected diabetic foot managed in general surgical department.

Background: Foot ulcers are diabetes-related complications which occur in 10%-25% in diabetic patients. They are an important cause of morbidity and mortality in diabetes. This retrospective study aimed to assess, using an administrative database, the morbidity and the mortality risk of infected diabetic ulcers.

Predictive factors for major amputation of lower limb in diabetic foot: about 430 patients.

Background: Major amputation of the lower limb is defined by a leg or thigh amputation. The aim of our work was identifying predictive factors for lower limb major amputation in patients with diabetes admitted on for foot lesions through using an administrative data base.

Methods: It was a retrospective study ranging from June 1st, 2008 to December 31st, 2011, which included all the patients admitted on for an infected diabetic foot to the surgery unit B of Charles Nicolle hospital in Tunis.

Alkalin phosphatase is a predictive factor of unresecability in ampullary and periampullary tumors.

Background: Patients with malignant obstructive jaundice should undergo surgery on the basis of results of preoperative imaging. However, about half of patients are found to be unsuitable forresection during surgical exploration. Our study aimed to determine the clinicobiologicalcharacteristics that predict the resecability of ampullary and periampullary tumors.

Treatment of inguinal hernia by lichtenstein technique: an open prospective study.

Background: Treatment of inguinal hernia is still a challenge for the surgeon. The multitude of surgical techniques attests of the difficulty of choosing the best procedure. In the surgical B department of the Charles Nicolle Hospital we have chosen the Lichtenstein technique since 2008.

A proposal for a test method for assessment of hazard property HP 12 ("Release of an acute toxic gas") in hazardous waste classification - Experience from 49 waste.

A stepwise method for assessment of the HP 12 is proposed and tested with 49 waste samples. The hazard property HP 12 is defined as "Release of an acute toxic gas": waste which releases acute toxic gases (Acute Tox. 1, 2 or 3) in contact with water or an acid.

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.

Selective extraction of PAHs from a sediment with structural preservation of Natural Organic Matter.

Selective extraction of Polycyclic Aromatic Hydrocarbons (PAH) without structural modification of the Natural Organic Matter (NOM) from a heavily contaminated sediment was investigated using various solvents mixtures. Structural modification of the NOM was monitored after extraction using 3D-fluorescence spectroscopy. Better results were obtained with a 15-h PAH extraction under reflux with a dichloromethane/cyclohexane 20/80 mixture.

[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.

Methods: It was a prospective study concerning 4690 hospitalisations in Department B of General Surgery of hôpital Charles Nicolle during a period of 18 months, between June 1st, 2008 and December 31st, 2009.

[Parietal abscess revealing a lost gallstone 8 years after laparoscopic cholecystectomy].

Background: Laparoscopic cholecystectomy is the treatment of choice for symptomatic gall stone disease. The perforation of the gallbladder happens in 40% of cases. Stones spilled remain there in 20% of cases in view of their number and location.
