CHU (University Hospital Center) Point G: The department of surgery B is a surgical department of CHU Point G. The department is par excellence a reference department for cases of visceral surgery, cancer surgery, cardiovascular surgery, plastic and endocrinology surgery. As a reminder, the CHU Point G is the largest 3rd level referral hospital in Mali. Aim: To study the environmental risk factors of stomach cancer in the B surgery department of the Point G University Hospital in Bamako. Patients and Methods: We performed a cross-sectional study with retrospective collection from January 2008 to June 2018 (126 months). Results: We have identified 380 cases of digestive cancer, including 193 cases of stomach cancer or 50.79% of digestive cancers. The mean age of the patients was 57.21 ± 13 years. Male sex represented 55% (n = 106). Eating habits were dominated by the consumption of t? with potash (cereal paste) with 64.76% (n = 185). The main methods of preserving meat and fish were curing and smoking with 57.51% (n = 111). Chronic smoking was found in 24.35% (n = 47), alcohol + tobacco consumption in 2.59% (n = 5). The low socio-economic class represented 126 cases or 65.38%. Housewives and cultivators were respectively 37.82% (n = 73) and 227.97% (n = 54). 20.20% (n = 39) had a history of epigastric pain. Epigastralgia was the most common functional sign with 84.5% of cases (n = 169). An epigastric mass was found in 72 patients or 37.3%. Adenocarcinoma represented 97.4% (n = 188). Palliative surgery concerned the majority of our patients with 64.8% of patients (n = 79). The postoperative consequences were simple in 28.57% of cases (n = 28), the postoperative morbidity and mortality were respectively 33.61% (n = 41), and 23.77% (n = 29). The overall survival rate after surgery was 10.81% at 2 years and 2.94% at 5 years. This rate was 58.83% at 2 years and 28.50% at 5 years after curative surgery. Conclusion: The risk factors for stomach cancer are many and varied. Some are particularly present in Africa. Delay in diagnosis due to a belief in traditional healers is common in our community.

Roughly quadrangular, the chiasma presents many morphological variations. The optical chiasm, odd and symmetrical structure of the optical pathways, is a required passage of the axons of neurons for the visual pathways. Any modification of its morphology evokes a pathological process, generally tumoral. The quality of MRI images rivals that of anatomical slices. So the MRI is essential for the study of the chiasma. The aim of this work was to study the morphometry of the optic chiasm in patients addressed for cerebral MRI to the imaging department of the university hospital of the POINT-G, during the period from July 29, to November 30, 2016. All patients who had a normal examination of the optic chiasma, numbering 15, were included in this study. In 86.66% of cases the chiasma had a quadrilateral form. Its average length was 8.73 mm and its average width was 13 mm. The average thickness was 4.13 mm.

Background: The sciatic nerve is the largest nerve in body. It is the only terminal branch of the sacral plexus. It emerges under the piriformis muscle, descends into the gluteal region, then into the posterior compartment of the thigh. It ends in the popliteal fossa by dividing into the tibial and common peroneal nerve. It is the most frequently injured nerve. The aim of this work was to study the mode of termination of the sciatic nerve by cadaveric dissection in a Malian population.Materials and methods: This was a cross-sectional study, carried out at the anatomy laboratory of the Faculty of Medicine and Odontostomatology of Bamako, ranging from December 2019 to April 2021. The sciatic nerve was dissected 74 times in 37 cadaveric subjects (29 men and 8 women).Results: The classic termination mode (the sciatic nerve terminates giving the tibial nerve and common peroneal nerve) was most frequently encountered with a prevalence of 82.43%. Anatomical variations were noted in 17.57%. Among these variations, trifurcation (termination in three branches) of the sciatic nerve was observed in 16.22%. Hexafurcation (six-branch termination) of the sciatic nerve was observed in 1.35%. The termination mode showed a significant difference being more frequently bilateral than unilateral (P˂0.05)Conclusion: Anatomical variations in the mode of termination of the sciatic nerve are not uncommon. The most common of these variations is the trifurcation in which the sciatic nerve ends up giving the tibial nerve, the common peroneal nerve and a third branch which is variable. Knowledge of these variations is important for surgeons when treating popliteal artery aneurysm, popliteal vessel fistula and popliteal fossa cysts.

Aim: The purpose of this work was to describe the left renal retro-aortic vein. Methodology: A case of left renal retro-aortic vein was discovered on a corpse of male, 45-year-old adult during the dissections to the laboratory of anatomy of the Faculty of Medicine of Bamako. The way at first was a xypho-pubic median and two side abdominal sections under costal and inguinal. The side sections under costal went of the median section to sides by following the costal edge. The inguinal side sections went of the median section to the anterior and superior iliac thorns. The abdominal wall was opened and reclined by every quoted. The small intestine and the colonist were resected with their meso. The renal pedicle was dissected on each side. The abdominal aorta and the inferior vena cava were dissected by the diaphragm up to the headland. Arteries and iliac veins were also dissected. Results: On male corpse, 45 years old, we discovered a left renal retro-aortic vein in horizontal route, and the trunk of the left renal vein was formed by the confluence of three veins at the level of the left renal hilum. The left renal vein passed almost horizontally below the left renal artery. It passed then behind the abdominal aorta to end in the inferior vena cava at the level of its left side face. The right renal vein had a normal aspect. Conclusion: The left renal retro-aortic vein is one of the variants of the anomalies of the system cellar inferior. The left renal retro-aortic vein could be responsible for renal aplasia.

The brachial plexus (BP), established by the lap twigs of the last four cervical nerves and the first thoracic nerve, assures the driving and sensory innervation of the thoracic member. We bring back a case of rare anatomical variation of the brachial plexus. It is a 34-year-old corpse dissected in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in September 2017. The lap twig of the fourth cervical root (C4) participated in the constitution of the brachial plexus. The superior trunk was normally constituted. The average trunk was formed by the cervical roots C7 and C8 instead of only C7. And consequently the inferior trunk was constituted by the thoracic root T1. The posterior beam was only formed by the posterior branches of the superior and more average trunk. The medial beam was formed by all of the inferior trunk which did not give posterior branch for the formation of the posterior beam. The variations of the brachial plexus could entrain failures in the loco regional anesthesia of the brachial plexus.

Objectives: The purpose of this work was to measure the dimensions of the femoral veins, to describe the affluent and the variations of the femoral veins. Methodology: Twenty-four femoral veins of 12 fresh adult cadavers were dissected and photographed. Results: The diameter of the superficial, deep and common femoral veins was respectively 8.75 mm; 7.60 mm and 13.95 mm. The common femoral vein was 80.70 mm long. At the level of the superficial vein, the modal disposition was noted in 79.17%; as anatomical variations, it was split in 2 cases, the presence of a collateral canal in 1 case and in 2, and it received a quadricipital muscle vein. At the level of the deep femoral vein, the modal disposition was noted in 16.67%, and the anatomical variations were noted in 83.33% where it received no affluent in the femoral trine. The modal disposition was noted in 91.67% at the level of the mode of birth of the common femoral vein, in 16.67% at the level of its tributaries. The anatomical variations were noted in 8.33% in the mode of birth of the femoral vein, in 83.33% in which the common femoral vein received, in addition to the large saphenous vein, other tributaries, the most frequent of which were the quadricipital veins and the circumflex femoral veins. Conclusion: The diameter of the femoral veins is important. The main tributaries of the common femoral vein are GVS, VQ and circumflex femoral veins. The femoral variations are numerous and important to know to avoid a possible misdiagnosis in case of their thrombosis.

The purpose of this study was to study the frequency of premature division of the inferior laryngeal nerve and its consequences in thyroid surgery. Methodology: We realized a forward-looking and retrospective study from January, 1979 till December, 2017 in the service of surgery B to the University hospital of the Point G of Bamako and in the service of ENT and cervico-facial surgery of the CHU “mother-child”, the Luxembourg of Bamako (Mali). All the patients operated in both services for mild goiters were included. Cancers and other thyroid pathologies were not included. The diagnosis of mild goiter was paused by the histological examination realized on all the surgical specimens. Results: On 2109 dissections of the lower laryngeal nerve realized during the surgical operations on the thyroid 95.1% of the cases, the nerve had a single branch; in 4.1% of the cases, the nerve had two branches; and in 0.8% of the cases, the nerve had more than 2 branches. Conclusion: The complications of the thyroid surgery in touch with the hurts of the lower laryngeal nerve are known. However, our study shows that these do not seem to be influenced by the premature division of the lower laryngeal nerve.

Aim: The aim of this work is to determine the dimensions and the capacity of the gall-bladder by ultrasound. Methodology: We realized a descriptive study over 2 years (from January, 2015 till December, 2017). It concerned an ultrasound exploration of the gall-bladder. The studied population was healthy voluntary subjects visible and on an empty stomach for 12 hours, without history of abdominal trauma and abdominal operating scar. The carrying subjects of the tracks of abdominal trauma or of abdominal operating scar were not included. Results: The average age was of 39 years ± 12.16 with extreme of 10 years and 89 years. It was 500 women (50%) and of 500 men (50%) with a sex ratio of 1. To 450 subjects (45%) the width of the gall-bladder of the subjects varied between 21 and 30. The average was 22.63 mm ± 7.9. Extremes were from 9 to 55 mm. The measurements made by the three sonographers showed no significant difference. The sensitivity of ultrasound in the visualization of the gallbladder was 100%. The length of the gall-bladder was between 61 and 70 mm. The average was 65.35 ± 14.48. Extremes were 26 and 142 mm. Conclusion: This original study shows the normal dimensions of the gall-bladder to Malian.

Aim: The purpose of this study was to determine the frequency of the hurts of the inferior laryngeal nerve, according to its anatomical reports with the inferior thyroid artery during the thyroid surgery. Methodology: We realized a forward-looking and retrospective study from January, 1979 till December, 2017 in the service of surgery “B” to the University hospital of the Point G of Bamako and in the service of ENT and cervico-facial surgery of the Teaching Hospital “Mother-Child”, the Luxembourg of Bamako (Mali). All the patients operated in both services for mild goiters were retained. Cancers and other thyroid pathologies were not included. The diagnosis of mild goiter was paused by the histological examination realized on all the surgical specimens. Results: On 2109 dissections of the inferior laryngeal nerve realized during the surgical operations on the thyroid, the frequency of lesion of the inferior laryngeal nerve was 1.09% (20 cases) when it passed dorsally with regard to the inferior thyroid artery (1837 cases) and when 4.04%, it was transvascular or prevascular (272 cases). Conclusion: The prevascular route or transvascular of the inferior laryngeal nerve favors its lesion per operating.

Aim: The aim of this study is to determine from a series of 1000 cases the usual dimensions of the portal vein according to the medical ultrasound. Methodology: We realized a transverse study over 2 years (from January 2015 to December 2017). It concerned an ultrasound exploration of the portal vein. The studied population was healthy voluntary subjects visible without history of abdominal trauma and abdominal operating scar. Results: The average age was 39 years ± 12.16 with extremes of 19 years and 70 years. The decade of 21 - 29 years represented 46.2%. The transverse diameter of the portal vein in its origin varied between 8 and 10 mm in 57.9% of the cases. The average was 9.05 ± 2.82 mm with extremes of 5 and 16 mm. The transverse diameter of the portal vein in its ending varied between 8 and 10 mm in 56.9%. In 29.8% of the cases, the length of the portal vein was between 61 and 70 mm and in 8.8% between 81 and 100 mm. The average length was 58 ± 22.3 mm. Before its penetration in the liver, the portal vein divided into 2 branches in 967 cases (96.7%) and in 3 branches in 33 cases (3.3%). Conclusion: This original study shows the normal dimensions of the portal vein to Malian.

Objectives: The purpose of this work was to determine the dimensions of CFA before the birth of the deep thigh artery, describe the mode of termination of the CFA, search for CFA collaterals, and describe the anatomical variations of the CFA. Methodology: This was a prospective study conducted at the Anatomy Laboratory of the Faculty of Medicine and Odonto-Stomatology of Bamako. CFA arteries of 12 fresh corpses of adults include 9 men and 3 women. A total of 24 CFA arteries were dissected and photographed. Results: The mean length of CFA was 50.9 ± 12.55 mm (range: 31 and 93 mm). Its average diameter was 9.12 ± 1.17 mm (range: 7 and 12 mm). In 70.83%, the CFA artery ended without any particularity. There was 29.17% anatomic variation in the CFA termination mode. The CFA divided into 3 branches (trifurcation) in 25%. The 3 branches were in 20.83%, the FS and a common core to LFCA and AQ; in 4.17%, they were the SFA, the DFA and the MFCA. In 4.17%, it divided into 4 branches which are: the SFA, the DFA, the MFCA and a common core to QA and LFCA. The CFA gave as collateral: circumflex superficial iliac artery in 22 cases (91.67%), superficial epigastric artery in 19 cases (79.17%), upper external pudendal artery in 20 cases (83.33%), and lower external pudendal artery in 14 cases (58.33%). We noted in our series 9 anatomical variations at the collateral level of the CFA or 37.5%. The CFA gave birth to the following branches: the MFCA in 4 cases or 16.67%, the LFCA in 1 case or 4.17%, the QA in 1 case or 4.17%, and a common core to the QA and LFCA in 3 cases or 12.5%. Conclusion: The length of CFA is important. The variations of CFA are frequent and important to know in clinical and surgical practice.

The objective was to study epidemiological and therapeutic aspects of the inguinal hernia according to the technique of Shouldice. Methodology: we realized a retrospective study, concerning the patients operated for inguinal hernia according to the technique of Shouldice in the service of general surgery of the hospital Somine Dolo of Mopti, Mali. All the patients operated during the period of study for inguinal hernia according to the technique of Shouldice were included. The patients operated for hernia by other technique than that of Shouldice were not included. Results: The study has been realized in the service of general surgery of the hospital Somine Dolo of Mopti (Mali). It was about a retrospective study which concerned 25 years from January, 1987 till December, 2012. 675 patients operated according to the technique of Shouldice were registered. The average age was of 49 years +/−17.7. There were 90.7% (612) men. The sex-ratio is 9.7. The farmers, the housewives and the workers represented 51.1% (115). In 75.2% (508) the patients consulted for inguinal tumefaction. In operating meadow, the hernia was complicated to 246 (36.4%) patients among whom 72 cases were of recurrence. The hernia constriction was the main complication operating meadow 58.5% (48/82). The operating suites in one year were simple at 94.2% (636) of the patients; they were marked by 24 cases of recurrence, 12 cases of neuralgia, 6 cases of testicular atrophy, and 3 cases of keloid. Conclusion: The technique of Shouldice is the technique of choice for the cure of the inguinal hernia in developing countries because of the good result and its little expensive cost with compared with the other techniques using medical devices.

Aim: This study aimed at describing the anatomical variations of the external branch of the superior laryngeal nerve and at estimating the frequency of nerves at risk during the thyroid surgery. Methodology: We realized a forward-looking study from September, 2016 in May 31st, 2018 in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in Mali. All the fresh anatomical subjects not carrying trauma and or a scar at the level of the previous region of the neck were held. The anatomical subjects were not included presenting a traumatic lesion and\or a scar of the previous region of the neck. Results: We realized 34 dissections of the external branch of the superior laryngeal nerve to 17 deathly subjects (11 men and 6 women with a sex-ratio of 1.8). The average age of the subjects was of 42 years (extremes: 18 and 70 years). Our study allowed highlighting in 100% of the cases, the external branch of the superior laryngeal nerve and the superior thyroid artery so to the right as to the left. On 34 dissected external branch of the superior laryngeal nerve, none had a previous route. However we found 28 nerves (82.4%) having a later route, stuck to the external face of the lower constrictor of the pharynx. These were not mixed with the superior thyroid artery and its branch of division and were situated outside the thyroid capsule. In 17.6% of the cases (6 cases), the nerve had a route mixed in the branch of the superior thyroid artery. These were found inside of the capsule (11.8% adhered to the artery and 5.8% crossed its branch of division). Conclusion: The risk of injury of the external laryngeal nerve during thyroid surgery procedure is never zero. It is more important on the left side.

Purpose: Our purpose was to describe the epidemiological and therapeutic aspects of the vaginal hydroceles. Methodology: It was a forward-looking and descriptive study of Mars 2014 in July, 2017, which realized in the service of general surgery of the Reference Health Center of Kati (Mali). All the patients operated in the service for hydrocele were included. Other causes of big stock exchange and hydroceles operated outside our service were not including. Results: We operated 92 hydroceles or 5.9% of the surgical activities of the service. The average age was of 34.5 years with extremes of 2 years and 82 years. The most frequent signs of hydrocele were the big painless stock exchange (100%); a transillumination positive (90%) and the effusion of the vaginal in the ultrasound (100%). The cure of hydrocele was realized according to the techniques of Bergmann (94.6%) and of Lord (5.4%). The mortality was nil and the morbidity was 3.3% (2 operating infections of the site and 1 bruise). Conclusion: The hydrocele is a frequent pathology in Africa. The therapeutic strategies are multiple and varied. However, we prefer the Bergmann technique, which is easy, fast and has few complications.

Purpose: Our purpose was to describe the anatomy of the external branch of the upper laryngeal nerve and to estimate the frequency of nerves at risk during the total thyroidectomies sub. Methodology: We realized in the CHU Point G in Bamako a forward-looking study over a period going from September 1st, 2016 till December 31st, 2017. All the patients operated by thyroidectomies subtotals for mild goiters were included to whom a systematic location of the external branch of the superior laryngeal nerve in the space avascular of Reeve was realized. Cancers and other thyroid pathologies were not included. Results: We counted and operated 120 cases of mild goiters. The external branch of the superior laryngeal nerve was seen and dissected in 80.8%; it was not seen in 19.2%. According to the classification of Cernea: the type 2 was found in 80.8% of the cases with him under typical 2b in 47.5% and under type 2a in 40 (33.3%). The global frequency of lesion of the external branch of the upper laryngeal nerve was 10.8% at 9 patients among whom 6 who presented a BENLS of Type Ni. Conclusion: The external branch of the upper laryngeal nerve of type 2 presents a risk of wound because the surgeon treats the upper pedicle at the level of the critical centimeter place over the upper pole of the thyroid. The identification of the nerve during the thyroid surgery is the solution of choice.

In 7 years, we brought together 100 cases of volvulus of the colon sigmoid to the hospital Somine Dolo of Mopti among which the handle volvule was found without necrosis in 66 cases and necrosis 34 cases. Seventy-six patients benefited from a sigmoidectomy followed by a colorectal anatomize at a time, twenty one patients of an intervention of Hartmann. A surgical distortion was realized at 3 patients. All the patients operated by these last two techniques had a restoring of the digestive continuity for an average deadline of 90 days. The post-operative complications consisted of 11 cases of parietal suppuration and a case of evisceration. The average duration of follow-up was of 210 days. The post-operative mortality was 14%. It was about a state of toxic shock with visceral multi-failure (n = 13), and of a pulmonary embolism (n = 1). The treatment of the volvulus requires a fast diagnostic and therapeutic coverage. The best treatment consists of a resection of the sigmoid as a matter of urgency followed by an immediate anastomosis if the following conditions are carried achieved: state general voucher, experimented surgeon and if the resuscitation meadow, per and post-operative can be assured.
