Prise en Charge des Appendicites Compliquées de l’Adulte à l’Hôpital National de Niamey

Objectif : rapporter les résultats de la prise en charge des appendicites compliquées chez l’adulte à l’Hôpital National de Niamey (HNN). Patients et méthode : Il s’agissait d’une étude rétrospective, descriptive et analytique sur 10 ans incluant tous les patients âgés de plus de 15 ans qui avaient été pris en charge pour appendicites compliquées à l’HNN. Résultats : durant la période de l’étude 8127 urgences abdominales avaient été enregistrées dont 1837 d’origine appendiculaire, parmi elles 512 étaient des appendicites compliquées (AC), soit 6, 30% des urgences abdominales et 27, 87% des appendicites. Il s’agissait de 337 (65, 82%) hommes et 175 (34, 18 %) femmes ; soit un sex ratio de 1, 92. L’âge moyen des patients était de 32, 83 [±14, 50] ans avec des extrêmes de 16 ans et de 90 ans. Le délai moyen d’admission était de 6 [±3, 82] jours avec des extrêmes de 1 et de 14 jours. Les AC retrouvées étaient la péritonite appendiculaire dans 74, 02% des cas (n =379) suivie de l’abcès appendiculaire dans 21, 48% des cas (n=110) et du plastron appendiculaire dans 4, 5%(n=23) des cas. Le traitement avait été opératoire dans 95, 5% des cas (n = 489). La voie d’abord utilisée était la laparotomie médiane dans 81, 05% des cas (n=415) et l’appendice était gangréné dans 95, 70% des cas (n=490) à l’exploration. Le geste le plus réalisé était l’appendicectomie dans 89, 84% des cas (n= 460). La durée moyenne d’hospitalisation était de 9 [±10, 61] jours avec des extrêmes d’un et de 76 jours. La morbimortalité globale était de 11, 52% avec 9, 96% de suppuration pariétale (n=51) et une mortalité de 1, 56% (n = 8) tous enregistrés parmi les cas de péritonite appendiculaire. Il existe une corrélation significative entre le type de complications et le délai d’admission (P=0, 00001).  Conclusion : Les appendicites compliquées sont fréquentes à l’HNN avec une morbimortalité importante. Le retard de la prise en charge constitue un facteur influencant la survenue des complications.   Objective: to report the results of the management of complicated appendicitis in adults at the National Hospital of Niamey (NHN). Patients and method: This was a retrospective, descriptive and analytical study over 10 years including all patients over the age of 15 who had been treated for complicated appendicitis at NHN. Results: during the study period, 8127 abdominal emergencies were recorded, of which 1837 were of appendicular origin, among them 512 were complicated appendicitis, i.e. 6.30% of abdominal emergencies and 27.87% of appendicitis. These were 337 (65.82%) men and 175 (34.18%) women; i.e. a sex ratio of 1.92. The mean age of the patients was 32.83 [±14.50] years with extremes of 16 and 90 years. The average admission time was 6 [±3.82] days with extremes of 1 and 14 days. Complicated appendicitis found was appendicular peritonitis in 74.02% of cases (n=379) followed by appendicular abscess in 21.48% of cases (n=110) and appendicular plastron in 4.5% (n= 23) cases. The treatment was operative in 95.5% of cases (n = 489). The approach used was the midline laparotomy in 81.05% of cases (n=415) and the appendix was gangrenous in 95.70% of cases (n=490) on exploration. The most performed procedure was appendectomy in 89.84% of cases (n = 460). The average duration of hospitalization was 9 [±10.61] days with extremes of one and 76 days. The overall morbidity and mortality was 11.52% with 9.96% parietal suppuration (n=51) and a mortality of 1.56% (n=8) all recorded among the cases of appendicular peritonitis. There is a significant correlation between the type of complications and the admission time (P=0.00001). Conclusion: Complicated appendicitis is common in NHN with significant morbidity and mortality. Delay in treatment is a factor influencing the occurrence of complications

Les malformations de Dandy-Walker : Aspects diagnostiques et apport de l’endoscopie : A propos de 77 cas

ObjectifDécrire les malformations kystiques de la fosse postérieure chez l’enfant et évaluer les indications et résultats thérapeutiques.MéthodeIl s’agit d’une étude prospective en série continue réalisée dans le service de neurochirurgie de l’hôpital national de Niamey (Niger) entre janvier 2007 et février 2012. Etaient inclus, les enfants de 0 à 5ans admis pour macrocranie ou retard psychomoteur sans antécédents de méningite chez qui un kyste malformatif de la fosse postérieure a été découvert au scanner. Une évaluation clinique et une classification scannographique a été réalisée pour chaque patient. L’indication opératoire a été retenue en présence de syndrome de la fosse postérieure associé ou non à une hydrocéphalie. En présence d’une hydrocéphalie le traitement était endoscopique de première intention (VCS + fenestration du kyste dans le ventricule latérale (VL) + cautérisation plexuelle partielle). Certains patients ont été classés selon les critères prédictifs des résultats de la VCS selon Warf. Une fontanelle non affaissée et tendue à 1mois post opératoire était considérée comme un échec. Seuls les patients suivis pendant au moins 6 mois ont été inclus dans l’étude.RésultatsLa série comportait 144 patients porteurs de kyste de la fosse postérieure soit 11,076% des enfants de 0 à 5 ans ayant réalisé un scanner en 5ans. La moyenne d’âge était de 8,7 mois (7 jours - 5 ans) avec un sexe ratio de 1,4. Il s’agissait de 67 cas de malformation de Dandy Walker (46,52%), de 21 cas de Dandy Walker variant (14,58%) et de 56 cas de kyste de la fosse postérieure considérés comme megacisterna magna ou kyste de la valecula ou Dandy Walker complex (38,88%). Sur les 144 patients porteurs de malformation kystique de la fosse postérieure l’hydrocéphalie était associée dans 128 cas soit dans 88,88% des cas. L’indication opératoire était retenue chez 77 patients suivis pendant au moins 6 mois (53,47%) dont 8 n’avaient pas d’hydrocéphalie (5,55%). Il s’agissait de 49 cas/ 67 de malformation de Dandy Walker, de 7 cas/21 de Dandy Walker variant, et de 21 cas/56 retenus comme des megacisterna magna ou de kyste de la valecula ou Dandy Walker complex. Le suivi moyen était de 16,4 mois (6 mois- 59 mois) avec au moins un scanner de contrôle à 6 mois post- opératoire. Le taux de succès du traitement endoscopique seul était de 57% à 6 mois.ConclusionLorsque l’indication opératoire est retenue pour une malformation kystique de la fosse postérieure associée à une hydrocéphalie, le traitement endoscopique peut être de première intention

Prise En Charge Des Victimes Du Conflit Armé Du Nord Mali Dans Les Hôpitaux De Niamey

Objectives: The aims of this study was to evaluate the management of lesions in victims of the malian conflict patients admitted to Niamey hospitals. Methods: A retrospective study was conducted in Niamey hospitals from January 1st, 2012 to December, 31th, 2013. Data collected included âge, sex, means of transport, topography of trauma, treatment and outcome. Results: The sample included fifty one (51) patients. All patients were male; the mean age was 29,5 years ± 9 years, ranging from 17-71 years. The age between 26 and 35 were most affected in 47% of cases (24 patients), soldiers represented 72.54% (37 patients); and civils 27.45% (14 patients). 74.50% of our patients (38) were been transported in Niamey by aircraft. The trauma concerned the members in 54.90% (28 cases), canio facial in 17.60% (9 cases), abdomen in 11.80% (6 cases). We observed only one polytrauma. 66.66% (34) of patients were injured by firearms, 29.41% (15) by accidents of roads, 3,93% by burn (2 patients). The lesions found were bone in 41.17% (21 patients), skin-muscle in 35.29% (18 patients), visceral in 9.80% (5 patients). Five patients died (9.80%). Conclusion: the internationalization of conflicts requires a reorganization of the care by involving all the nearness health structures in order to ensure adequate care and neutrality

Les Occlusions Intestinales Par Nœud Ileo-Sigmoïdien : Aspects Diagnostiques, Thérapeutiques Et Pronostiques

Introduction: Ileosigmoid knot (ISK), also known as compound volvulus or double volvulus, is a rare disease and affects mostly male subjects in their fourth decade. Delayed diagnosis often leads to complications with a high incidence of digestive necrosis. Materials and methods: This was a 10-year retrospective, descriptive and analytical study from 1 January 2007 to 31 December 2016, which covered all patients operated emergently for ISK in the surgical and surgical specialty departments at the Niamey National Hospital (NNH). Results: The series involved 8 cases of ISK, representing 0.82% of intestinal obstructions. There were 7 men and 1 woman. The average age of patients was 44.33 years with extremes ranging from 25 to 60 years. The main clinical signs were: abdominal pain (100%), inability to pass gas and stool (100%), vomiting (87.5%) and abdominal meteorism (87.5%). Four patients (50%) had a clear obstructive syndrome and the other 4 patients (50%) had associated signs of peritoneal irritation. Paraclinical diagnosis was difficult because of atypical clinico-radiological signs, but in all cases an abdominal x-ray was performed and showed a double loop of dilated sigmoid shadow in 87.5% of the cases. Laparotomy was the first approach used in all patients and led to a 50% necrosis rate. Hartmann’s colectomy and ideal colectomy were used in identical proportions, with 50% each. Ideal colectomy was characterized by a morbidity rate of 50% and a mortality rate of 25% compared to 0% for Hartmann’s procedure. The overall morbidity was 25% and the overall mortality was 12.5%. The average hospital stay was 65.87 days (range 17 to 128 days). The average time before reestablishment of digestive continuity was 50.37 days (range 31-128 days). Conclusion: Ileosigmoid knot is a rare condition at Niamey national hospital where the diagnostic approach is similar to that of occlusions in general, but remains difficult due to its uncommonness and atypical clinico-radiological signs. Necrosis rates and postoperative complications remain high

Invagination Intestinale Aiguë De L’adulte: Aspects Diagnostiqsues, Thérapeutiques Et Étiologiques

Introduction: Acute intussusception is a rare clinical entity in adults where it accounts for only 1-2% of intestinal obstructions. The authors wanted to report cases of acute intussusception in adult patients, their diagnostic aspects, their management, and their etiologies. Patients and Methods: This study is a retrospective study of the medical files of patients of both sexes. They include adults over 15 years of age, operated between January 2010 and December 2014, who were diagnosed with obstruction due to acute intestinal intussusception. Results: Six cases of adult intestinal intussusception were collected. The average age was 26.5 years. The sex ratio was 1 and there were so many men as women. Five out of six patients were unstable on admission. The diagnosis was made preoperative in two cases out of six, 33.3%. Ultrasound revealed a target sign in two cases. The ileo-ileal form was the most frequent (5 cases out of 6) or 83.3%. Also, there were two cases of intestinal necrosis out of six. Intestinal resection was performed in five cases or 83.33%. The cause of intussusception was found in four cases out of six or 66.7%. Here, a tumor was the cause in half of the cases. Immediate surgical follow-up was uncomplicated in all patients. Conclusion: Acute intestinal intussusception of the adult is a very rare condition. The preoperative diagnosis of acute intussusception of the adult remains delicate. The ileo-ileal form is more frequent than the ileo-colic form in adults. Treatment is always surgical in adults

Cholécystectomies Laparoscopiques Pour Cholécystite Aigue Lithiasique Versus Lithiase Vésiculaire Symptomatique

Introduction: The aim of this work was to highlight the therapeutic and prognostic difficulties between a laparoscopic cholecystectomy for acute gallstone cholecystitis (CAL) and uncomplicated symptomatic vesicular lithiasis (LVS) as well as the reasons for conversion to laparotomy. Patients and Methods: This was a prospective comparative and analytic study over 18 months. Patients admitted and operated for CAL or LVS in the A Surgery Department of the National Hospital of Niamey (HNN) were included. Results: The study involved 61 patients divided into two groups. Group 1 (30 patients) corresponding to patients operated for CAL, group 2 (31 patients) corresponding to patients operated for LVS. Laparoscopic cholecystectomy accounted for 61% of all cholecystectomies performed and 1.45% of surgical activity during the same period. The average age in group 1 was 43.7 years with extremes of 14 and 61 years. In group 2, the average age was 38.9 years with extremes ranging from 12 to 55 years. Women were predominantly represented with 63.3% and 96.7% respectively for groups 1 and 2. Patients were overweight in 9 cases for group 1 (30% of cases) and 12 cases in group 2 (38%), 7% of cases). Hepatic colic was the main sign of appeal in all patients in both groups. In group 1; 26 out of 30 cases or 86.7% of cases had leukocytosis, whereas in group 2, leukocytosis was normal in 30 cases, ie 96.8% of cases. Accessibility of the vesicle was difficult in 73.3% of cases in group 1 against 22.6% of cases in group 2. The vesicle was distended and necrotic in groups 1 in 76.7% and 10 respectively. % of cases. On the other hand, in 25.8% of cases, the vesicle was distended and without any necrosis in group 2. The rate of conversion to laparotomy was 6.55% (4 cases) and exclusively concerned group 1. Operative follow-up immediate outcomes were simple in 98.34% of cases. The complications involved 2 patients in group 1 (1.66% of the total), including parietal suppuration and biliary leakage. Mean operative time was 68.7 min in group 1 versus 41.6 min in group 2. Mean duration of hospitalization was 4.3 days with extremes between 2 and 10 days in group 1 versus1,7 days with extremes ranging from 1 to 7 days in group 2. Mortality was zero. Conclusion: In recent years, laparoscopic surgery has made remarkable progress in Niger. Laparoscopic cholecystectomy seems to be more difficult to perform with significant morbidity in the case of CAL than LVS. The risk of per and postoperative complications can be estimated from the clinical data (acute cholecystitis or symptomatic vesicular lithiasis) and the surgeon's experience. In a cholecystectomy that lasts more than 2 hours, the cumulative risk of complications is highe

Prise En Charge Des Anévrismes Artériels Dans Un Centre Africain Non Spécialisée

Introduction: Arterial aneurysms affect 7 to 8% of people over 65 in the West and are the 2nd leading cause of death in these countries. In Africa this frequency is poorly evaluated. The objective of this work is to report the management of arterial aneurysms at the National Hospital of Niamey (HNN). Patients and methods: This was a retrospective, descriptive study over a period of eight (8) years from January 2009 to December 2016, performed in the surgical departments of the National Hospital of Niamey. Included in the study were patients of both sexes, hospitalized and / or operated for arterial aneurysm. Not included were patients treated for arterial aneurysm with incomplete records or those concerning the neurosurgical sphere. Results: During the study period, 17,748 patients were hospitalized in the general surgery departments, including 16 patients for arterial aneurysm, or 0.09% of surgical pathologies. There were 13 men (81.25%) and 3 women (18.75%), or a sex ratio of 4.33. The average age was 55.75 years with extremes ranging from 25 years old to 90 years old. The circumstances of discovery of the aneurysms were swelling of the antero-internal aspect of the thigh in 7 cases (43.75%), abdominal mass 6 cases (37.50%), then 2 cases (12.50%) of chest pain and incidental discovery in 1cas (6.25%). The most common risk factor was high blood pressure with 43.75% (7 cases). The aneurysm sat on the femoral artery in 43.75% (n = 7), of which 6 on the deep femoral and 1 on the superficial femoral, on the infrarenal aorta in 31.25% (n = 5), on thoracic aorta 12.50% (n = 2), on the iliac artery 12.50% (n = 2). For the diagnosis the angioscanner is realized in all the patients and in addition Doppler ultrasound in 43, 75% of cases. Twelve (12) patients benefited from curative surgical intervention by prosthetic graft by PTFE in 58.33% of cases and by Dacron in 41.66%. The average stay was 29.75 days and the immediate operative followup was complicated by thrombosis in 12.5% and parietal suppurations in 6.25%. We recorded two (2) deaths, ie 12.5% among non-operated patients. Conclusion: Arterial aneurysms are rare diseases at the HNN. Conventional surgery is the treatment performed in our patients. The postoperative course was simple in most cases

Management of postoperative pain: experience of the Niamey National Hospital, Niger

Maman Sani Chaibou,1 Samuila Sanoussi,2 Rachid Sani,2 Nouhou A Toudou,1 Hadjara Daddy,1 Moussa Madougou,1 Idrissa Abdou,1 Habibou Abarchi,2 Martin Chobli31Department of Anesthesiology and Intensive Care, 2Department of Surgery, The Niamey National Hospital, Niamey, Republic of Niger; 3Department of Anesthesiology, Hubert K Maga University Teaching Hospital, Cotonou, BeninObjective: The aim of this study was to evaluate the management of postoperative pain at the Niamey National Hospital.Methods: A prospective study was conducted in the Department of Anesthesiology and Intensive Care at the Niamey National Hospital from March to June, 2009. Data collected included age, sex, literacy, American Society of Anesthesiologists (ASA) physical status classification, type of anesthesia, type of surgery, postoperative analgesics used, and the cost of analgesics. Three types of pain assessment scale were used depending on the patient's ability to describe his or her pain: the verbal rating scale (VRS), the numerical rating scale (NRS), or the visual analog scale (VAS). Patients were evaluated during the first 48 hours following surgery.Results: The sample included 553 patients. The VRS was used for the evaluation of 72% of patients, the NRS for 14.4%, and the VAS for 13.6%. Of the VRS group, 33.9%, 8.3%, and 2.1% rated their pain as 3 or 4 out of 4 at 12, 24, and 48 hours postoperatively, respectively. For the NRS group, 33.8%, 8.8%, and 2.5% rated their pain as greater than 7 out of 10 at 12, 24, and 48 hours postoperatively, respectively. For the VAS group, 29.3%, 5.4%, and 0% rated their pain as greater than 7 out of 10 at 12, 24, and 48 hours postoperatively, respectively. Conclusion: Postoperative pain assessment and management in developing countries has not been well described. Poverty, illiteracy, and inadequate training of physicians and other health personnel contribute to the underutilization of postoperative analgesia. Analysis of the results gathered at the Niamey National Hospital gives baseline data that can be the impetus to increase training in pain management and to establish standardized protocols.Keywords: postoperative pain, pain scales, Niamey National Hospita
