The endoscopic surgery is actually the golden standard for the management of infertility. Its results look better than classical surgery. The aim of the study was to assess the fertility rate among infertile women who have undergone a laparoscopic distal tubal plasty and to estimate factors influencing this fertility. From January 2007 to December 2016 a descriptive and analytical cross sectional retrospective study was conducted in the departments of general and laparoscopic surgery of the Point “G” Teaching Hospital in Bamako, Mali. Clinical records of 120 laparoscopic patients with distal tubal occlusion who have undergone a neosalpingostomy were collected. Average period of infertility was 6.7 years (from 1 to 25 years), and the average duration before laparoscopic surgery was 5 years. Main abnormalities were: 50 cases of bilateral tubal distal occlusion (41.7%), 14 patients with unilateral tubal distal occlusion (11.7%), 44 cases of bilateral hydrosalpinx (36.6%) and 12 cases with unilateral occlusion (10.0%). Seventeen patients had adhesions (14.1%) including 4.0% of tubo-peritoneal adhesions, 35.5% of tubo-ovary adhesions and Fitz Hugh and Curtis syndrom adhesions in 17.7% of cases. More than half of the patients (58.0%) had a grade II tubal score. Neosalpingostomy had led to bilateral tubal repermeabilization among 60.0% of the patients. Thirty two point five percent (39/120) pregnancies have been observed after the management. Conception probability was null after the 4th post operative year. The majority of pregnancies have been observed in the 11th month after laparoscopic management. During the follow-up, thirty one patients had intrauterine pregnancy (79.5%), four ectopic pregnancies and three miscarriages. The occurrence of pregnancy was influenced by the desire of the woman, the absence of co-morbidity, the tubal score, the result and the quality of the laparoscopic gesture and the duration of the fertility. Conclusion: In our working setting, neosalp

Perforation of a pseudo appendicular tumor of bilharzial origin (bilharzia) is a rare etiology of acute peritonitis. His diagnosis is histopathological. The existence of comorbid malaria and surgical pathology is frequent in having a positive thick drop with Schistosoma mansoni eggs in his stool. After 3 months, the patient is doing well. In conclusion, we recommend the histopathological analysis of the surgical specimen after appendectomy and the detection of haematozoa for malaria in any case of fever in a surgical environment.

Splenic infarction is a rare condition (1/500,000 and 1/100,000) but potentially fatal. The prognosis depends on the diagnostic delay and above all on the speed of treatment. It usually occurs in a particular area such as myeloproliferative syndrome, sickle cell anemia, thalassemia etc. The objective of this work was to report a clinical case of necrosis of the spleen.

Total or partial thyroidectomy has been proposed as the initial treatment for benign euthyroid oiter. The aim of this study is to determine the complications associated with surgical procedures for goiter, based on our experience. Material and method: A retrospective study over 10 years concerning 409 patients operated on for goiters in the department with 48 cases of complications. Results: 409 patients operated on for goiter in the department with 48 cases of complications (11.82%). The per- and post-operative complications were: hemorrhage (18: 4.40%), recurrent lesions (1;0.24%), 8 cases of infection (1.96%), 5 cases of transient hypocalcemia (1.22%) and phonation disorders 9 cases (2.20%). Conclusion: Complications from goiter surgery seem to be more related to thyroid disease and the surgeon’s experience than to the surgical procedure. Better knowledge of the factors leading to complications will improve the outcome of goiter surgery.

The residual biomass composed of pseudo trunks and banana leaves is very important and poorly valued. There is very little quantified data on the deposits of residual biomass from banana plantations in Senegal and in particular in the Tambacounda region. In this work, we seek to evaluate the methanogenic potential and to valorize this biomass in biogas and biofertilizer. The laboratory experiment lasted approximately 35 days. During this time, the methanogenic microorganisms degrade the organic residue provided, which results in the production of biogas. At the end of the reactions, the rate of biogas production drops, indicating the end of the biodegradation of organic matter. Biogas production is measured over time and the composition of the biogas produced is analyzed by gas chromatography (GC) or by an infrared analyzer. The methane potential of each sample is determined from the cumulative quantity of methane produced in each flask representing a digestion system. The measurement can be expressed in m3 of CH4 per tonne of dry matter or per tonne of raw material. The first challenge of this study therefore lies in the acquisition of reliable and usable data to quantify the methanizable biomass. This study will allow us not only to evaluate the quantities of pseudo trunks and banana leaves available in a plot after harvest but also to test the biogas and methane production potential (BMP test) of this substrate and therefore determine the expected biogas production of this biomass.

We consider the problem of viscosity solution of integro-partial differential equation( IPDE in short) with one obstacle via the solution of reflected backward stochastic dif ferential equations(RBSDE in short) with jumps. We show the existence and uniqueness of a continuous viscosity solution of equation with non local terms, if the generator is not monotonous and Levy's measure is infinite.

The most commonly used method for assessing the hydraulic erodibility of rock is Annandale's *** method is based on a correlation between the erosive force of flowing water and the capacity of rock resistance. This capacity is evaluated using Kirsten's index, which was initially developed to evaluate the excavatability of earth materials. For rocky material, this index is determined according to certain geomechanical factors related to intact rock and rock mass, such as compressive strength of intact rock, rock block size, discontinuity shear strength and relative block structure. To quantify the relative block structure, Kirsten(1982) developed a mathematical expression that accounts for the shape and orientation of the blocks relative to the direction of flow. Kirsten's initial concept for assessing the relative block structure considers that the geological formation is mainly fractured by two joint sets forming an orthogonally fractured system. An adjusted concept is proposed to determine the relative block structure when the fractured system is non-orthogonal where the angle between the planes of the two joint sets is greater or less than 90°. An analysis of the proposed relative block structure rating shows that considering a non-orthogonally fractured system has a significant effect on Kirsten's index and, as a consequence, on the assessment of the hydraulic erodibility of rock.

The general objective of our study was to describe the clinical and epidemiological aspects of anxiety disorders. This was a retrospective descriptive cross-sectional study, lasting 5 years, from January 01, 2019 to December 31, 2023, on 225 patients seen in consultation for anxiety disorders in the department. The prevalence of anxiety disorders was 2.5% in consultation. The 20 - 29 age group was the most represented at 33.3%. Females were slightly represented at 55.1%, with a sex ratio of 1.2. The secondary level was the most affected, accounting for 36.4% of cases. Insomnia was the most frequent reason for consultation, accounting for 71.1% of cases. A larger general population study would be necessary to better assess the extent of anxiety disorders in Guinea.
