[Penetrating wound of the abdomen. Profile of the suffering patient at Dakar teaching hospital].

INTRODUCTION: In Senegal, the rate of penetrating wound of the abdomen seems to be in great progression. The purpose of this study was to make a descriptive analysis of the epidemiological data on the patient suffering from a penetrating wound of the abdomen. MATERIAL AND METHOD: It is about a retrospective study performed on a 5 years period from January 1997 to January 2002. This study covered 90 cases of penetrating wounds of the abdomen listed at the emergency department of Dakar teaching hospital. The rate, age, sex, responsible agent, circumstances of the wound, place of the injury, evacuation mode, time of admission and check-up injury were studied. RESULTS: The average absolute rate of the penetrating wounds of the abdomen was 18 cases per year. The average age was about 27 +/- 10 years with 88 men for 2 women. The responsible agent was a knife (87%), a firearm (6%), a broken glass (4%), a bullock horn (2%) and a piece of iron (1%). Circumstances of the injury was aggression (91%), accident (6%), self-mutilation (2%), suicide attempt (1%). Evacuation was done by firemen (60%), by the ambulances of the medical structures (22%), and by private individuals (18%). The average time of admission was 5 hours. Nearly 61% of the wounds were located in the umbilical, epigastric, left hypochondre and left side areas. Wound was single in 93,4% of cases and linear in 71,8% of cases. We noted an exit of epiploon (38 cases), peritoneal signs (13 cases) and a small bowel evisceration (9 cases). The treatment was a systematic laparotomy (68%) and a simple closure of the wound with a good follow-up for any further aggravation (32%). CONCLUSION: The patient admitted at the surgical emergency unit of Dakar teaching hospital for penetrating wound of the abdomen is generally a young man, victim of aggression by knife, evacuated by firemen within 5 hours, which present a single and linearwound in perish-umbilical area with exit of epiploon and/or small bowel evisceration, which would undertaken a surgical operation in 68% of cases.

The arch of the great saphenous vein: anatomical bases for failures and recurrences after surgical treatment of varices in the pelvic limb. About 54 dissections.

The arch of the great saphenous vein presents numerous tributaries. Misappreciation of their anatomical variations might cause recurrence after surgical treatment of varices. We dissected 54 inguino-femoral regions of fresh, black African corpses. Our purpose was to study the anatomical variations in the vein confluents of the arch of the great saphenous vein; its positions in relation to the external pudendal artery; establish palpable anatomical markers for its surgical approach. The conventional type in a 'vein star' shape was not the most frequent. Upper or abdominal common vein produced through the merging of superficial veins of the anterior abdominal wall and genital or internal common vein were more frequent. An anterior saphenous vein was found in 23 cases. The external pudendal artery crossed beneath the arch of the great saphenous vein cross in 56% of cases and previously in 44% of cases. On average, the top of the arch of the great saphenous vein was projected out 10.88 cm from the ventral and cranial iliac spine, 3.83 cm from the pubic tubercle and 4.19 cm from the inguinal ligament. In view of our results, variations are real. Knowing and taking them into account are essential to prevent recurrences after surgical treatment of varices of the pelvic limb.

[Cadaveric topography and morphometry of the vermiform appendix].

Our study justified by the frequency of acute appendicitis and the possibility of anatomic variations of the caecoappendicular area attempt to index the topographic variations of the vermiform appendix (v.a.). On 80 fresh native cadavers (62 men and 18 women) without surgical antecedent whose mean age was 36 years (range between 16 and 78 years) we note the morphotype and the height. More over we study the intraperitoneal projection of the Mac Burney point, topography and shape of the cecum and the situation, shape and dimensions of the v.a. We note also the level of implantation of this latter on the cecum, appearance of the mesoappendix and the distance separating the base of the appendix to the ileo-caecal junction. Mac Burney's point permitted to localize appendix in 66%; the cecum has more often than not the form of a bulb (98.7%) and sited in right fossa iliaca. We noted 7 types of topographic disposition; front varieties were more frequent (68.7%) notably the pelvic direction (51.2%) with a medial (72.5%) or a posteromedial (27.5%) establishment on the cecum. The v.a. was more often in the form of worm with a long mesoappendix; his mean length was 106.4 mm (between 65 and 160 mm) and the mean diameter 6.77 mm (range between 4 and 10 mm). The distance which separated the base of the appendix to the ileo-cecal junction varied between 15 to 40 mm with a mean distance of 24.2 mm. Thus in this study, dimensions of the v.a. were very variables. Located in right fossa iliaca he adopted a front topography with pelvic direction and medial establishment on bulbar cecum. In spite of scarcity of ectopic situation of the appendix for which laparoscopic approach is salutary, a similar topographic study during surgical treatment of acute appendicitis will be interesting.

[Complications of treatment of adult's groin hernia: a report of 100 cases comparative study between Bassini and Mac Vay's technics].

The authors report a prospective study comparing pre and immediate post operative complications of non complicated hernia of the groin in adult treated by operations based on Bassini and Mac Vay technics. It concerned a total of 100 patients made up of two groups of 50 age ranging from 13 to 84 years with an average age of 47 years of whom were 93 males and 7 females. No mortality was registered. The rate of complications was 20% in Bassini's technic and 22% in Mac Vay's technic. There were: bladder injurie, accidental skin wound incurred by the electric surgical blade, meningeal irritation, urinary retention, scrotal sac hematoma, parietal suppuration, intestinal occlusion and immediate recidivation before 6 months. As well as our study as in literature, specific complications related to both technics were rare. We could draw the conlusion that there is no significant superiority of one technic in comparison with the other one.

[About the tributaries of the arch of great saphenous vein. Concerning 40 dissections].

The arch of the great saphenous vein cross receives numerous tributaries from the abdominal wall, male external genitalia and pelvic limbs. These collaterals present many variations relating to their number and mode of anastomosis. Their misappreciation may lead to post operative recurrences after surgical treatment of varices. For a last study of these variations, we dissected 40 inguinofemoral regions in fresh black african corpes. The conventional type in a "vein strar" shape was present in 4 cases. An abdominal common vein produced through the merging of the superficial epigastric and superficial circumflex iliac veins was found in 5 cases. A genital common vein summarising the external pudendal veins was present in 19 cases. In 8 cases the abdominal and genital common vein was simultaneously present. An anterior saphenous vein was found in 15 cases, and a posterior saphenous vein in 5 cases. These results, confirm the importance of anatomic variations. Their knowledge is necessary to avoid recurrences after surgery of varicose veins.

[A case report of intrapelvic foetal osseous remains localization after clandestine caused abortion].

A 26 year old women, unmarried, second gesture, primiparous, had been hospitalized in our departement for the management of a hypogastric mass. Ultrasonography had shown: an uterus of normal size, a normal uterine vacuity line with presence of many osseous and fibrous constituents inside the inter-vesico-uterine area, including one femoral osseous of 18,6 mm corresponding to 15 weeks of amenorrhoea. A few months before, the patient had undergone a clandestine caused abortion on a progressive intrauterine pregnancy of 12 weeks of amenorrhoea certified by ultrasonography. It is an exceptional complication of clandestine caused abortion. It gives the opportunity to us to discuss its etiopathogenic mechanism. It also enables us to point out the complications of the clandestine caused abortion and to insist on the need for its prevention.

[Liver arterial ischemia after cephalic pancreatico-duodenectomy. A case report].

Cephalic pancreaticoduodenectomy is the best treatment for cephalic pancreas cancers. A rare complication is the liver ischemia after the divison of gastroduodenal artery. This complication can occur when a celiac trunk stenosed by the median arcuate ligamentous is not recognised. We report the case of a 40 old woman who underwent cephalic pancreaticoduodenectomy for an adenocarcinoma of pancreas head. There was no complication immediatly. Two weeks later, she presented two episodes of angiocholitis. An abdominal tomodensitometry showed a liver arterial ischemia associated with a celiac trunk stenosis. There was a left hepatic artery wich came from the left gastric artery. Medical treatment of the angiocholitis was successful. Surgical revascularization was not necessary. Nine months after, arterial revascularization by the left hepatic artery and biological hepatic tests were restored. This case report talks about the importance of angioscanner before pancreatic surgery when celiac and mesenteric angiography is not available. Also, it underlines the importance of the gastroduodenal artery occlusion test before his ligation during pancreaticoduodenectomy.

[Sciatic nerve in gluteal portion: application of sciatic nerve post injection lesion].

In our regions malaria is endemic and intraguteal injection is a common procedure. One unfortunate complication of that procedure appeared to be a sciatic nerve injury. The purpose of our study was to set up the anatomical feature and basis of this post injection lesion. We performed sciatic nerve gluteal dissection on 10 adults black African fresh cadavers on both side. The pathway of the nerve was 19 times in the subpiriformis canal. Only in one cadaver, the outlet of the nerve was above the piriformis muscle. In each case the pathway is identical with an oblique and vertical portion running down through the ischio-trochanteric channel. The nerve was crossed between its two portions by an arteriole coming from the inferior gluteal artery. The cutaneous projection of the sciatic nerve is distant from the upper lateral quadrant of the buttock. Intra-gluteal injections in this area doesn't damage the nerve. The anatomical variations of this nerve pathway are almost nonexistent. So, other hypothesis of sciatic nerve post injection lesion should be considered. We think that the local toxicity of quinine and its diffusion in the neurovascular gluteal area might explain the nerve lesion. Thus, the intramuscular injections should be replaced by the intravenous or rectal administration in children.

[Treatment of incisional hernias].

Several therapeutic processes were proposed in the repair of incisional hernia, on the basis of simple joining suture go to the installation of prosthetic mesh while passing by aponeurotic autoplasty according to Welti-Eudel technique. The aim of this study was to report the results of our experiment in the treatment of incisional hernias. It was a retrospective study carried out of January 11th 1996 to December 31, 2000, concerning 35 cases of incisional hernias operated during the study period. The following parameters were studied: age, sex, diameter, technique of repair, morbidty, mortality and the remote follow-up. Average age of our patients was 33 years with extremes of 13 and 53 years. It include 30 womens and 5 mens. The initial operation were dominated by Caesarean (57%). The diameter of incisional hernia varied between 3 and 5 cm in 22.9% of patients, between 5 and 10 cm in 62.8% of paitents, higher than 10 cm in 14.3% of patients. The simple joining suture was carried out in 22.9% of cases, the Welti-Eudel technique in 42.9% of cases and the installation of prosthetic mesh in 34.2% of the cases. Mortality was 5.1% and the morbidity was 34.2% made exclusively by suppuration including 5.1% on prosthetic material. We noted 14.3% of recurence which has occured after repair by simple joining. The Welti-Eudel procedure gives good results in the repair of incisional hernia with small and average dimensions. The installation of prosthetic mesh constitute the treatment of choice because the rate of recurence is weak even null.

[Solitary ulcer of the rectum. Report of two cases treated by the Orr-Loygue technique].

We report two cases of solitary ulcer of the rectum treated by Orr Loygue rectopexy technique in a ten-year period at the Surgery Department of Aristide Le Dantec. The first case is about a 39 year-old female who was constipated since approximately seventeen years and had a rectal prolapse associated later to bloody stools. In 1990, she underwent haemorrhoids surgery operation with unsatisfactory results. After the recurrence of the disease, she was admitted at Aristide le Dantec Teaching Hospital, rectoscopy revealed a solitary ulcer. Orr Loygue rectoplexy technique was performed by laparotomy. In the follow up, there was no complication. The second case is about a 43 years old female who suffered from rectal syndrome since twenty years and had pelvis pains with bleeding and phlegmatic diarrhoeas. The physical examination and biologic analysis showed no particularity. Rectoscopy has revealed a solitary ulcer of the rectum which was confirmed by biopsy. Orr Loygue rectoplexy technique was performed. In the follow-up, there was a recurrence and this was confirmed by rectoscopy. The rectopexy alone does not summurize the therapeutic. A final dyskesia or an associated perineal insufficiency must be integrated in a total therapeutic strategy.

[Laparoscopic cholecystectomy in sickle cell disease].

STUDY AIM: Sickle cell affection is a public health problem in Africa. The aims of this prospective study were to evaluate the early results of laparoscopic cholecystectomy in sickle cell patients in Senegal. METHOD: From January 1998 to June 2002 all the sickle cell patients undergoing a laparoscopic cholecystectomy were included. Intra- and post-operative protocol (blood transfusion if Hb < 9 g/dl, rehydration, oxygenotherapy) was standardized. RESULTS: Forty-two patients with sickle cell of types SS-33 and AS9 were operated upon by same surgeon. One case of conversion due to an effraction of biliary junction was reported. One homozygote patient died post-operatively because of peritonitis. Two acute thoracic syndromes, three vaso-occlusive crisis, and two cases of wound infection constituted the post-operative morbidity. No case of complication was noted in those who underwent pre-operative transfusion. CONCLUSION: Laparoscopic cholecystectomy can be carried out in sickle cell patients with biliary lithiasis provided that general anaesthetic rules are respected.

[Vascular dysplasia in vascular surgery in an African area: 28 cases at the Dakar teaching hospital].

This retrospective study was conducted to analyze the anatomic and clinical data concerning vascular dysplasia in vascular surgery patients seen in an African hospital and to assess its role in treatment. Twenty-eight patients (14 women and 14 men) were treated for vascular dysplasia between 1994 and 1998. There were 8 cases of hemangioma and 20 cases of vascular malformation. Average age of patients with hemangioma was 3.23 years, with a sex ratio of 0.33. There were 4 cases of mixed hemangioma, 3 of cutaneous hemangioma, and 1 of subcutaneous hemangioma. Cervicocephalic (n=4) and limb (n=3) localizations were the most frequent. Duplex Doppler did not reveal any signs of muscle disease. Four patients underwent surgery, for an early indication in 3 and a late indication in 1. Resection suture was performed in 3 cases and resection graft in one. Mean follow-up was 85.90 days. There was one case of early suppuration. There were no cases of recurrence or late complications and the operative wounds healed well. Vascular malformations concerned 20 patients (sex ratio 1.5, average age 15.55 years) with 16 cases of venous malformation including 4 patients with Klippel Trenaunay syndrome, three with arteriovenous malformation and one with capillary angioma. CT and arteriography were obtained in all cases. Limb localizations predominated (14 patients). In-depth extension was found in 6 cases of venous malformation. Sixteen patients underwent surgery for functional indications in 7. Resection suture was performed in 11 cases. Mean follow-up was 85.90 days. There were 4 early and 2 late postoperative complications. There has been no recurrence. Anatomic and clinical polymorphism of vascular dysplasia requires multidisciplinary collaboration in which vascular surgery plays an important role in complex or complicated forms of the disease in patients attending facilities with limited resources.

[Results of emergengy colectomy in the management of the colon volvulus in Dakar hospital].

PURPOSE: The aim of this study was to evaluate the results of emergency colectomies for the management of colon volvulus. PATIENTS AND METHODS: This retrospective study was undertaken on 50 cases of colon volvulus operated in the Surgical Department of the Aristide Le Dantec teaching hospital of Dakar from January 1994 to December 2000. It concerned 42 men and 8 women with an mean age of 42 years. All patients presented an occlusive syndrome suggestive of colon volvulus, which required a laparotomy, through a xypho-pubic incision. The patients were divided into two groups. Group I concerned 13 patients who underwent an ideal colectomy and group II, 37 patients in whom we performed a colectomy associated with a temporary colostomy with either Bouilly-Volkman procedure (n = 23) or Hartman procedure (n = 14) followed one month later by intestinal continuity restoration. Mortality and morbidity were compared in the two groups. RESULTS: The overall mortality rate was 12% (6/50). The mortality rate was 31% (4/13) in group I and 5 % (2/37) in group II. The overall morbidity rate was 14%. In group I, the morbidity rate was 15 % (2/13) and 13,5% (5/37) in group II. CONCLUSION: In our study the mortality rate was higher after colectomy with primary anastomosis than after colectomy with temporary colostomy followed by secondary anastomosis. We recommend colectomy without anastomosis for the emergency management of the colon volvulus in Africa.

[Topographic anatomy of the tibial nerve in the medial malleolus: application to the effect of nerve block anesthesia].

To better understand the anatomical variations and pathogeny of tarsal tunnel syndrome, the tibial nerve were dissected in 20 ankles of fresh black African cadavers. The tibial nerve located to 1.75 cm on average from the posterior side of the malleolus and to 2 cm from medial side of the calcaneus tendon. The nerve always ended according to dichotomic method. 90% cases of bifurcation were noted under the flexor retinaculum at 1 cm from the malléolo_calcaneus line; in 10% of dissections, we found proximal bifurcation at 5 cm from this line. The medal calcaneus branch which is a collateral branch of tibial nerve was constant, unique in 80% of cases and double in 20% of cases. The anatomical constatations allow a more precise anesthesia of tibial nerve block. We use constant anatomical marks formed by calcaneus tendon and internal malleolus tip. Olso we more understand the possibility of lesion of tibial nerve at the ankle during the synovites, or ossifications of flexor rétinaculum.

[Uterine leiomyoma at the surgical department of the Teaching Hospital of Dakar. Report of 140 cases operated in two years].

Uterine leiomyomas due to complications in particular mechanical and haemorrhagic constitute a frequent motive of consultation to the surgical department at the university hospital of Dakar. To precise its epidemiologic, clinical and therapeutic aspects, a prospective study of two years (1995-1996) was made. Hundred and forty patients operated for uterine leiomyoma in our department were brought together. Uterine leiomyoma represent 58.82% of the gynaecological disorders operated to the surgical department. These gynaecological affection constitute 15% of the whole surgical pathology. The edge of age most concern was the decade 49-59 years old. The infertility and the low parity were found in 55.14% of the cases. The average delay of consultation was 39 months. The clinical symptoms amounted it metrorrhagia (72%) abdominal or pelvic pains (77.1%) and increase of the volume of the belly (96.4%). The overall reoperating rate was 3.5%. The pelvic ultrasonography allowed to confirm the diagnosis in 84.28% of the cases. The under umbilical laparotomy (90.9%) was the main surgical way. The sub-total hysterectomy was carried out in 35.72% of the cases. The average duration of hospitalization was 9 days and the mortality 0.7%. Main postoperative complications were parietal abscess (16 cases), evisceration (2 cases) and eventration (2 cases). Histological examination realized in 48.06% of the cases confirmed the diagnosis of uterine leiomyoma in every case. In 17.82% of the cases leiomyoma were associated to another lesion and in two cases it was a neoplasm of the uterine cervix. Uterine leiomyomas are frequent in Dakar. Their often impressive volume and metrorrhagia dominant their occasion of diagnosis. Their sufficiently early diagnosis have to noticeably reduce their radical surgery indications in this benign pathology whose association with cervix uterine cancer stays very rare in our daily practical experience.

[The Burch intervention: report of 24 patients].

The Burch standard colposuspension consist with the suspension of the bladder cervix and the urethral segment to the pectinate ligament from the vaginal wall, in order to reposition the bladder cervix inside the manometric abdominal pression. The aim of this study was to evaluate our results in this technic. It was a retrospective study including all cases of Burch colposuspension, carried out in our departement. This study covered over one 6 years period, from January 1995 to January 2001. Twenty four patients underwent this type of intervention during the study period. The average age of the patients was 45.4 years old. The natural menopause was noted in 45.8% of the cases. The multiparous patients constituted 95.8% of the cases and the 4.2% were the nulliparous ones. A pelvic surgical gesture was carried out in 16.6% of the cases in patient medical past-history. A dystocic childbirth in the patient medical past-history was found in 20.8% of the cases. The missing rate into post-operative near period (urinary incontinence) was 8.4%, therefore 91.6% of good results was observed. The rate of good results into post-operative late period was 84.2%. The Burch colposuspension provides good immediate post-operative results with very little rate of failure. Nevertheless a delayed degradation of long-term results is usual.

[Long term course after thyroidectomy for euthyroid nodular goiter].

Every patient operated for nodular goiter by a partial surgery is exposed to recurrence. In order to verify this idea, the authors followed 36 patients operated on for nodulargoiterat least 10 years ago. A clinical examination for all the patients and echographic study for 24 of them allowed the detection of recurrence and the evaluation of survival and recurrence without any opotherapy. It seemed that clinical recurrence is observed in 16.65% of cases whereas echographic study revealed recurrence in 50% of patients examined. Only two patients were reoperated on. The predictive factors of the recurrence are geographic endemic origin and ethny, partial surgery and vesicular goiters. With 66.65% of survival without recurrence at 18 years without opotherapy, the authors argue about the utility of such treatment.

[Anatomical and surgical study of the medial calcaneus branch of the tibial nerve].

To better understand the anatomical variations of the medial calcaneus branch, the tibia nerve were dissected in 20 ankles of fresh black African cadavres. The medial calcaneus branch which is a collateral branch of tibial nerve was constant. It was unique in 80% of cases and was detaching itself from the trunck of the tibial nerve ot the entrance of the calcaneal sulcus. It was in the form of two small nerves with point of departure from the common tibial nerve trunk. These anatomic constatations confronted with those published in literature permits us to understand the etiopathogenic aspects of certain neuropathies of the ankles. To add this they impose a certain order if precaution in the operational surgnical route of the posterior section of the ankle.
