Pre-and Post-Prostatectomy Detrusor Wall Thickness and the Symptom Profile in Patients with Benign Prostatic Enlargement: A Prospective Review.

INTRODUCTION: The urinary bladder undergoes morphological and functional changes in patients with symptomatic benign prostatic enlargement (BPE). These detrusor changes reflect chronically increased intravesical pressure as a result of outlet obstruction. This study aims to determine the relationship between the Pre- and Post-op detrusor wall thickness (DWT), international prostate symptom score (IPSS), and duration of lower urinary tract symptoms (LUTS) in patients who had open simple prostatectomy (OSP). METHOD: This was a prospective study of a cohort of patients who had OSP for symptomatic BPE. The IPSS and symptom duration for each patient were noted. Each patient also had an abdominal ultrasound scan with a measurement of their DWT. Retropubic OSP was done for each patient. The detrusor wall thickness was also measured 12 weeks after the prostatectomy. RESULTS: Fifty-two patients completed the study; the mean age was 66.37 ± 8.09 years. The median pre-operative IPSS was 28 (IQR = 13.75), and the median duration of symptoms was 24 months (IQR = 37 months). The mean pre-operative DWT was 4.41 ± 1.38mm, while the mean post-operative DWT was 2.16 ± 0.98mm. The preoperative IPSS (p = 0.833) and duration of symptoms (p = 0.375) did not significantly correlate with the pre-operative DWT. There was a significant reduction in the mean DWT (p < 0.001) and IPSS (p < 0.001) following prostatectomy. CONCLUSION: DWT appears not to be significantly influenced by the severity or duration of LUTS. However, it reduced significantly following OSP with corresponding improvement in urinary symptoms.

INTRODUCTION: La vessie subit des changements morphologiques et fonctionnels chez les patients présentant une hyperplasie bénigne de la prostate (HBP) symptomatique. Ces modifications du détrusor reflètent une pression intravésicale chroniquement augmentée en raison de l'obstruction de la sortie. Cette étude vise à déterminer la relation entre l'épaisseur de la paroi du détrusor (EPD) avant et après l'opération, le score international des symptômes prostatiques (IPSS) et la durée des symptômes des voies urinaires inférieures (LUTS) chez les patients ayant subi une prostatectomie simple ouverte (OSP). MÉTHODE: Il s'agissait d'une étude prospective d'une cohorte de patients ayant subi une OSP pour une HBP symptomatique. L'IPSS et la durée des symptômes pour chaque patient ont été notés. Chaque patient a également subi une échographie abdominale avec mesure de leur EPD. Une OSP rétropubienne a été réalisée pour chaque patient. L'épaisseur de la paroi du détrusor a également été mesurée 12 semaines après la prostatectomie. RÉSULTATS: Cinquante-deux patients ont terminé l'étude ; l'âge moyen était de 66,37 ± 8,09 ans. L'IPSS médian préopératoire était de 28 (IQR = 13,75), et la durée médiane des symptômes était de 24 mois (IQR = 37 mois). L'EPD moyenne préopératoire était de 4,41 ± 1,38 mm, tandis que l'EPD moyenne postopératoire était de 2,16 ± 0,98 mm. L'IPSS préopératoire (p = 0,833) et la durée des symptômes (p = 0,375) n'ont pas significativement corrélé avec l'EPD préopératoire. Il y a eu une réduction significative de l'EPD moyenne (p < 0,001) et de l'IPSS (p < 0,001) après la prostatectomie. CONCLUSION: L'EPD ne semble pas être significativement influencée par la gravité ou la durée des LUTS. Cependant, elle a considérablement diminué après l'OSP avec une amélioration correspondante des symptômes urinaires. MOTS-CLÉS: Hyperplasie bénigne de la prostate, Épaisseur de la paroi du détrusor, Score international des symptômes prostatiques, Prostatectomie simple ouverte.

Effectiveness of Triclosan Coated Suture for Subcutaneous Wound Closure in Preventing Surgical Site Infection following Mesh Repair of Inguinal Hernia: A Pilot Study.

BACKGROUND: The role of prophylactic antibiotics in mesh repair of inguinal hernia is controversial and often based on institutional policies. Surgical site infection rate from earlier studies in Nigeria justifies the continued use of prophylactic antibiotics during hernia repair. With increased use of antibiotics comes the challenge of antibiotic resistance and toxicity. The use of antimicrobial coated suture may help avoid these challenges but its efficacy needs to be tested. OBJECTIVE: To compare Triclosan coated suture with intravenous antibiotics for the repair of inguinal hernia with mesh. METHODS: Patients with uncomplicated inguinal hernia undergoing mesh repair were randomized to either have intravenous antibiotics administered for prophylaxis or to have wound closure with Triclosan coated Vicryl 2/0 suture. Post operatively, wound infection rates were compared between the two groups. Follow up was for 1 year. RESULTS: We studied 49 patients with 59 hernias with a mean age of 53 years. Hernias were solitary in 75% of cases, the majority of which were right sided, while 25% were bilateral. There were 25 patients with 32 hernias in the Intravenous antibiotic group (Group A) and 24 patients with 27 hernias in the Triclosan suture group (Group B). Wound grades were similar between the two groups with one patient in the Triclosan group confirmed to have wound infection (4.2%) and none in the Intravenous antibiotics group (p=0.27). Wound infection was of the superficial type which resolved with wound care within 1 month. CONCLUSION: Triclosan coated suture may be safely used as an alternative to intravenous antibiotics for the mesh repair of inguinal hernia. Further studies are required to validate this finding.

RÉSUMÉ: Le rôle des antibiotiques prophylactiques dans la réparation par maille de la hernie inguinale est controversé et souvent basé sur les politiques institutionnelles. Le taux d'infection du site opératoire d'études antérieures au Nigeria justifie l'utilisation continue d'antibiotiques prophylactiques pendant la réparation d'une hernie. L'utilisation accrue des antibiotiques pose le défi de la résistance et de la toxicité aux antibiotiques. L'utilisation d'une suture enduite d'un antimicrobien peut aider à éviter ces défis, mais son efficacité doit être testée. OBJECTIF: Comparer la suture enduite de triclosan avec des antibiotiques intraveineux pour la réparation de la hernie inguinale avec un filet. MÉTHODES: Les patients présentant une hernie inguinale non compliquée subissant une réparation par filet ont été randomisés pour recevoir soit des antibiotiques par voie intraveineuse à titre prophylactique, soit une fermeture de la plaie avec une suture Vicryl 2/0 revêtue de triclosan. Après l'opération, les taux d'infection des plaies ont été comparés entre les deux groupes. Le suivi a duré 1 an. RÉSULTATS: Nous avons étudié 49 patients avec 59 hernies avec un âge moyen de 53 ans. Les hernies étaient solitaires dans 75 % des cas, majoritairement du côté droit, tandis que 25 % étaient bilatérales. Il y avait 25 patients avec 32 hernies dans le groupe antibiotique intraveineux (groupe A) et 24 patients avec 27 hernies dans le groupe suture au triclosan (groupe B). Les grades des plaies étaient similaires entre les deux groupes avec un patient dans le groupe Triclosan confirmé pour avoir une infection de la plaie (4,2%) et aucun dans le groupe antibiotiques intraveineux (p=0,27). L'infection de la plaie était de type superficiel qui s'est résolue avec le soin de la plaie en 1 mois. CONCLUSION: La suture enduite de triclosan peut être utilisée en toute sécurité comme alternative aux antibiotiques intraveineux pour la réparation par maille de la hernie inguinale. D'autres études sont nécessaires pour valider ce résultat. MOTS CLÉS: Hernie au triclosan, infection.

Percutaneous Endoscopic Gastrostomy in Ile-Ife, Nigeria:An Initial Report.

BACKGROUND: Protein-energy malnutrition is a common problem in critically ill patient and it is a major cause of accelerated morbidity and mortality in this group of patients. Recent dramatic advances in both enteral and parenteral nutritional support have ensured that most of these critically ill patients are adequately nutritionally supported. Unfortunately, most of these advancements in nutritional supports are far from the reach of most patients in developing countries. In this report, we highlighted the indications, success, challenges of the use of percutaneous endoscopic gastrostomy (PEG) in Nigeria patients. PATIENTS AND METHODS: All cases of PEG performed at the Endoscopy Unit of Obafemi Awolowo University Teaching Hospitals complex, Ile-Ife, Osun State from January 2011 and June 2012 were recruited into the study. The data obtained included the sociodemographic parameters, indication and duration of the procedure, complications, and follow up. RESULTS: During the 18 months study period 645 upper gastrointestinal endoscopic procedures were performed. Majority [601(93.2%)] of the cases were for diagnostic purposes. Six (0.9%) cases of PEG were performed. Most (5 of 6) of the patients had central nervous system impairment while only one had severe chronic facial infection with naso-oral fistula. The median age of patients was 60.5 years. The entire procedure including endoscopy lasted an average of 25 minutes with a range of 12-35 minutes. Only one case had peristoma infection which resolved with antibiotics and repeated dressing with povidone iodine. There was no episode of aspiration pneumonitis or procedure related mortality. The average follow up was 6 months with variable weight gain during the follow up period. CONCLUSION: PEG is a simple, cost effective and safe method to rehabilitate nutritionally all chronically ill patients in less developed countries such as Nigeria. The need to increase awareness and acceptability of PEG among physicians managing such patients and the society cannot be overemphasized.

Riedel's thyroiditis in a black African: A case report and review of literature.

Riedel's thyroiditis is a rare cause of the enlargement of the thyroid gland. The etiology is not fully known. There has been no report of Riedel thyroiditis in our country. We report a case of a 61-year-old man with the disease as well as review the literature. We present the case of 61-year-old carpenter seen in our clinic with 2½ years history of painless anterior neck swelling associated with hoarseness of voice. He had multiple hard nodules on the left lobe of the thyroid gland with multiple cervical lymph nodes enlargement. No feature of hypothyroidism or thyroiditis. Clinical diagnosis of malignant goiter was made although Fine-needle aspiration for cytology did not suggest malignancy. He had surgery, findings included nonresectable hard multinodular left thyroid lobe from which a wedge biopsy was taken, Histology of the specimen revealed Riedel's thyroiditis. He was managed with oral Prednisolone and Tamoxifen with remarkable improvement in his clinical symptoms. Riedel's thyroiditis is a rare disease. It can easily mimic malignant goiter hence proper histological diagnosis will be necessary to differentiate. Review of medical literature showed that Riedel thyroiditis has not been reported in a black African patient inhabiting the sub-Sahara Africa. This was a report of Riedel thyroiditis in a black Nigerian patient that was successfully managed on oral glucocorticoid, tamoxifen and L-thyroxine.

Pattern and outcome of traumatic gastro- intestinal injuries in ile-ife.

AIMS AND OBJECTIVES: Trauma continues to assume a prominent role in the cause of disease in the developing world with increased westernization. This study highlights the pattern, management and outcome of gastrointestinal injuries following abdominal trauma in our hospital. PATIENTS AND METHODS: A descriptive retrospective study of all patients who had laparotomy following abdominal trauma at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife between January 2008 and April 2013. RESULTS: A total of 120 patients had laparotomy following abdominal trauma. Forty- five patients comprising 41 males and 4 females whose ages ranged between 14 and 65 years had gastrointestinal injuries. Majority (68.9%) were in the third and fourth decades with penetrating injury occurring in 55.6% .Causes of injury included gunshots (44.4%), road traffic accidents (37.8%), stabs (8.9%), falls (6.7%) and impalement (2.2%). The small intestine was the commonest site of injury (57.8 %) irrespective of the mechanism. Gut perforations accounted for 71.1% of all injuries. Two-thirds of patients had other associated injuries with retroperitoneal trauma being the commonest associated intra-abdominal injury. Majority (44.4%) had bowel resection and anastomosis with surgical site infection recorded in 35.6%. Overall mortality was 6.7% and this was significantly associated with pre-operative blood transfusion (p<0.05). CONCLUSION: Gut perforations from gunshot especially of the small intestine are the commonest gastro-intestinal injury in our setting. Pre-operative blood transfusion, perhaps indicating severity of injury, implies poor prognosis.

Selenium levels in neoplastic breast lesions.

AIMS AND OBJECTIVES: The aim of this prospective case controlled study was to evaluate the tissue levels of selenium in patients with cases of fibroadenoma, cancer of the breast and in the controls in order to relate them to the occurrence of breast diseases. SUBJECTS AND METHODS: Consecutive consenting patients who had histologically confirmed breast cancer and fibroadenoma attending the General surgical outpatients departments of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, were recruited for the study. One gram of core disease breast tissues was taken for Selenium level estimation. RESULTS: There were 127 female subjects;. 95 (74.8%) cases of fibroadenoma and 32 (25.2%) of breast cancer. While breast cancer was common on the left, fibroadenoma was more common on the right breast (? = 8.994; p=0.011). The median tissue level of selenium in patients with fibroadenoma was 0.0272 mg/g with a range of 0.0124 to 0.0576 mg/g and that of the cancer patients was 0.0178 mg/g with a range 0.0072 to 0.0436 mg/g. These were statistically significantly different ( p=0.001). Factors affecting tissue selenium level include age (p<0.001), overall stage of breast cancer (p<0.001), maximum length of breast mass (p=0.023), previous delivery (p=0.004), age at last confinement (p=0.007), parity (p<0.001), oestrogen receptor (ER) status (p<0.001) and progesterone receptor (PR) status (p=0.021). CONCLUSION: Tissue selenium was lower in breast cancer than in fibroadenoma; Tissue selenium inhibits carcinogenesis; low tissue level of selenium therefore may be a factor in the development of breast cancer.

Presentation, distribution pattern, and management of diverticular disease in a Nigerian tertiary hospital.

BACKGROUND: Colonic diverticular disease is one of the most common and costly gastrointestinal disorders among industrialized societies, which have recently been described among Africans. Presentations and distribution pattern of the disease among Africans appeared to be different from that described among the Western population. We embark on this study aimed at evaluating the presentation, distribution pattern, and the management of diverticulosis in our tertiary health facility. MATERIALS AND METHODS: A prospective descriptive study of the cases of diverticular disease seen between January 2007 and December 2011 at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Osun State, Nigeria. RESULTS: During the 5-year study period, 40 cases were seen. The patients were aged 41-85 years with a median age of 64 years. There were 29 (72.5%) male and 11 (27.5%) female with an average male to female ratio of 3:1. The most common presentation was bleeding per rectum in 28 (70%) patients, which mostly needed transfusion. Ten (25%) patients presented with recurring abdominal pain, whereas one (2.5%) patient presented with abdominal mass and features of intestinal obstruction. Thirty patients were diagnosed on colonoscopy, eight on barium enema, and two on computerized tomography scan. Thirty-four (85%) patients had a pancolonic disease. All the patients were placed on high fiber diet and antibiotics namely ciprofloxacin and metronidazole. Five patients had recurrence within 6 months of follow up, of which one had emergency colectomy. CONCLUSION: Diverticular disease is no longer a rare disease in Nigeria. It is a common cause of lower gastrointestinal bleeding in elderly patients. High index of suspicion for diverticular disease of the colon and its complications should increase in the country.

Characteristics of inflammatory bowel disease in three tertiary health centers in southern Nigeria.

BACKGROUND: Inflammatory bowel disease (IBD) refers to two chronic inflammatory disorders of the gastrointestinal tract which is generally believed to be rare in most African countries. The objectives of the current study were to present the experience of three tertiary gastroenterology centers in southern part of Nigeria on IBD, highlighting the age distribution of the patients seen, management and the impact on the quality of their life in university-based community-type practices in Nigeria. METHODS: This was a retrospective review of charts of inflammatory bowel disease seen between January 2007 and June 2010 at three teaching hospitals in Southern Nigeria. Diagnosis of IBD was made from clinical manifestations, colonoscopic and histopathological findings. RESULTS: During the study period, 12 patients presented with clinical features consistent with inflammatory bowel disease. There were 8 (66.7%) males and 4 (33.3%) females and had ages ranged from 18 years to 80 years with a median of 26.5 years. Eight (66.7%) patients had ulcerative colitis while 4(33.3%) had Crohn's disease. Ten (83.3%) patients had severe disease with main clinical features being recurrent diarrhoea and passage of mucoid bloody stools. All the patients had treatments with sulphasalazine or mesalazine, steroids and antibiotics with good responses. One patient died following the occurrence of toxic megacolon. CONCLUSION: Although IBD is uncommon in Nigeria, high index of suspicion is necessary by attending physicians managing patients with recurrent passage of mucoid bloody stools. Prompt gastroenterological referral and judicious use of colonoscopy and biopsy will assist in making the diagnosis.

Spectrum of colonoscopy findings in Ile-Ife Nigeria.

AIMS AND OBJECTIVES: Lower gastrointestinal (LGI) diseases are the leading causes of morbidity and mortality worldwide. Colonoscopy holds an important place in screening, diagnosing and treatment of these conditions. In Nigeria, as in many other developing countries, the facility for performing colonoscopy is rarely available. This prospective report seeks to evaluate the demographic data of patients presenting for colonoscopy, the pattern and validity of referral diagnosis versus colonoscopy findings in Ile-Ife, Nigeria. SUBJECTS AND METHODS: All patients who had colonoscopy procedure done in the Endoscopy Unit of Obafemi Awolowo University Teaching Hospital Complex between January 2007 and December 2011 were included in the study. RESULTS: During the study period, colonoscopy was carried out in 320 patients. One hundred and eighty two (56.9%) were males, while 138 (43.1%) were females. The median age was 59.5 years. Their ages ranged from 2-87 years. The most common indications were lower gastrointestinal bleeding and change in bowel habit which together accounted for 79.0%. No abnormality was seen in 93(29.1%) patients. Abnormal endoscopic findings included 66(20.6%) patients who had haemorrhoids, 50(15.6%) cases colorectal cancer, 33 (10.3%) patients had benign polyps and (30 (9.4%) patients had diverticular disease. Other findings were colitis, inflammatory bowel disease, rectovaginal fistula, vascular ectasia and extra luminal compression. Haemorrhoids, diverticulosis and polyps were the most common findings in patients presenting with lower gastrointestinal bleeding. CONCLUSION: This present report showed that colonoscopy is a cheap, safe and effective method of investigating lower gastrointestinal disease in Ile-Ife, Nigeria. When the indication is based on symptoms, the diagnostic yield could be as high as 90%. The common causes of lower gastrointestinal bleeding in Ile-Ife, Nigeria include haemorrhoids, diverticulosis and polyps.

Evaluation of tension-free mesh inguinal hernia repair in Nigeria: a preliminary report.

BACKGROUND: Tension-free mesh inguinal hernia repair is becoming increasingly popular worldwide. However, reports are sparse in Nigeria. OBJECTIVE: To evaluate the impact, outcome and cost implication of tension free inguinal hernia repair in a Nigerian setting. METHODS: A prospective study of all consecutive adults patients with uncomplicated inguinal hernia who had mesh repair over a period of 12 months was undertaken. A large sheet of 900cm2 polyproylene mesh material was used for all the patients in the study. All wounds were opened on the third postoperative day while sutures were removed on the eight day. Patients were followed up for one year. RESULTS: A total number of 30 patients had tension-free mesh ingunal hernia repair. Their ages ranged from 21 to 78 years (mean 47.2±15.5) years with a female to male ratio of 1:15. Complete inguinoscrotal hernia was the commonest type of groin hernia accounting for 40% of the cases. The repair of posterior wall which entailed placement of mesh was completed at a median time of 15 minutes. While two (6.7%) and one (3.3%) had wound oedema and groin pain respectively at one month, none of the patients had these complications or recurrence at a median of five months follow-up period. CONCLUSION: Tension-free mesh inguinal hernia repair was well tolerated and affordable to our patients. Pain and infections, reported to be the common complications of this procedure were infrequent in this study. A larger study is recommended to help confirm these findings.

Bowel preparation for colonoscopy: enema versus sodium phosphate.

BACKGROUND: Colonoscopy is considered to be the gold standard investigation for assessing the colonic mucosa. Good bowel preparation is essential in order to achieve optimal visualisation of the mucosa. Traditionally water enema is used for bowel preparation in most centres in Nigeria. This prospective study was performed at the Gastrointestinal Endoscopy Unit of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria between July 2008 and June 2009. AIMS AND OBJECTIVES: This study compared patients' tolerability, adverse effects, efficacy and mean duration of colonoscopy of water enema and sodium phosphate (NaP) for bowel preparation toward colonoscopy. PATIENTS AND METHODS: Standard structured questionnaire was completed by 64 patients and the colonoscopist assessing tolerability, adverse effect, efficacy and mean duration of the procedure. RESULTS: There were sixty four patients aged between 22 to 86 years. The mean age was 58.16 ± 15.790. Thirty eight (59.4%) patients were in patients and 26 (40.6%) were out patients. Forty one (64.1%) patients had water enema while 23 (35.9%) patients were included in the NaP group. The median age for patients in both groups was 62.0 years. Patients in NaP group rated their bowel preparation as more tolerable and found the dietary restriction much easier than those in water enema group (p < 0.0001). Better colon cleansing score was found in patient in NaP group as compared with those in water enema group in all region of the colon. The procedure took significantly longer time in patients in water enema group as compared with those in NaP group (p < 0.0001). CONCLUSION: NaP has a better bowel cleansing score for colonoscopy than water. It has better tolerability, side effect profile, efficacy and gives a shorter mean duration for the procedure.

Determinants of splenectomy in splenic injuries following blunt abdominal trauma.

INTRODUCTION: The management of splenic injuries has shifted from splenectomy to splenic preservation owing to the risk of overwhelming post-splenectomy infection (OPSI). This study aimed to identify the factors that determine splenectomy in patients with isolated splenic injuries, with a view to increasing the rate of splenic preservation. PATIENTS AND METHODS: Files of 55 patients managed for isolated splenic injuries from blunt abdominal trauma between 1998 and 2007 were retrospectively analysed using a pro forma. Management options were classified into nonoperative, operative salvage and splenectomy. RESULTS: The majority of patients suffered splenic injury as a result of motor vehicle accident (MVA) trauma or falls. Splenectomy was undertaken in 33 (60%) patients, 12 (22%) had non-operative management, and operative salvage was achieved in 10 (18%) patients. Significant determinants of splenectomy were grade of splenic injury, hierarchy of the surgeon, and hierarchy of the assistant. DISCUSSION: MVA injury and falls accounted for the vast majority of blunt abdominal trauma in this study. The rate and magnitude of energy transferred versus splenic protective mechanisms at the time of blunt abdominal trauma seems to determine the grade of splenic injury. Interest in splenic salvage surgery, availability of technology that enables splenic salvage surgery, and the experience of the surgeon and assistant appear to determine the surgical management. CONCLUSION: Legislation on vehicle safety and good parental control may reduce the severity of splenic injury in blunt abdominal trauma. When surgery is indicated, salvage surgery should be considered in intermediate isolated splenic injury to reduce the incidence of OPSI.

Comparative study of collagen and elastin content of abdominal wall fascia in inguinal hernia and non-hernia patients in an African population.

PURPOSE: Altered composition of collagen and elastin in abdominal fascia has been linked with the pathogenesis of hernias. This has not been studied amongst Africans who have hernia presentations which vary significantly from Caucasian cohorts. The aim of this study was to determine, and compare, the collagen and elastin contents of the transversalis fascia and rectus sheath of inguinal hernia patients with non-hernia controls. METHODS: Twenty-five patients with solitary, primary, uncomplicated inguinal hernia and twenty-five non-hernia controls were evaluated. Biopsies of the transversalis fascia and anterior rectus sheath were stained with Masson Trichrome and Verhöeff van-Gieson to isolate collagen and elastin respectively, which were quantified using the ImageJ/Fiji® image analysis software. RESULTS: Inguinal hernia patients were aged 19-85 years with a mean age of 45.2 years, mean body mass index (BMI) of 23.3 kg/m2 and mean duration of hernia of 42.5 months. Lateral hernias with no hernia defect or posterior wall defect [PL0] were the predominant clinical type. There were significantly lower collagen and higher elastin content in the transversalis fascia and rectus sheath of inguinal hernia patients [P < 0.001]. Regression analysis identified smoking and long duration of hernias as independent predictors of low collagen levels in this study CONCLUSION: Inguinal hernia patients in the study population demonstrated depleted collagen in the connective tissue of the inguinal canal. This might justify the routine use of prosthetic mesh for the reinforcement of the posterior wall during hernia repair.

Use of commercial mesh for hernia repair in a low resource setting: experience after 500 cases.

BACKGROUND: The use of mesh has revolutionized the management of hernias in many parts of the world. There is, however, limited experience on its use in sub-Saharan Africa. This study describes a single hospital experience after 500 cases of mesh hernia repairs in a sub-Saharan African country. METHODS: We reviewed the records of the first 500 cases of abdominal wall hernia operations performed using commercial mesh since year 2007. Socio-demographic characteristics, hernia type, method of repair and outcome data were analyzed and presented as descriptive statistics. RESULTS: The first 500 cases of mesh hernia repairs were performed between 2007 and 2017 during which a total of 1,175 hernia operations were carried out, mesh repair accounting for 42.5% of the total. There was a progressive rise in the uptake of mesh repairs over time, with mesh repairs overtaking tissue based repairs in the last few years of the review. Inguinal hernia was by far the commonest indication for mesh use (80.4%), followed by incisional hernia (9%). Polypropylene mesh was the most common type of mesh used in about 96.2% of cases. Overall, there were seven recurrences (1.4%) at a mean follow-up period of 15.3 months (1-108 months) CONCLUSION: In spite of resource limitations, the use of mesh for hernia repairs continues to rise and has overtaken tissue-based repairs in a sub-Saharan African setting. Results show good outcomes justifying continued use.

Relations of the neck of groin hernias to pubic tubercle.

OBJECTIVE: The traditional anatomical and surgical teaching is that any hernia with the neck above and medial to the pubic tubercle are inguinal. Present day surgical authors and teachers mostly adhere to this teaching but observe a difference in this relationship in clinical demonstrations. This confuses most medical students and surgical residents. This all-important clinical teaching should hence be revisited. Hence this study was to ascertain and validate clinically the true relationship of pubic tubercle and the neck of groins hernia. DESIGN: Aprospective observational study. SETTING: Surgical Outpatient Clinic of Wesley Guild Hospital, Ilesa Unit of the Obafemi Awolowo University Teaching Hospital Complex, Nigeria. SUBJECTS AND MEASUREMENTS: Consecutive patients seen in the clinic with uncomplicated groin hernias were studied from January 1993 to December 2004. Examinations were done to ascertain the relationship of the groin hernias to the pubic tubercle. RESULTS: 96.8% of inguinal hernias have their necks above and lateral to pubic tubercle while all femoral hernia had their necks below and lateral to the pubic tubercle. CONCLUSION: Location above or below the pubic tubercle should be used as the sole difference between femoral and inguinal hernias in clinical demonstrations. More observations and inguinal dissections will be necessary for further clarification.

Single versus two layer suturing for wound closure after inguinal hernia repair.

OBJECTIVE: Method of skin-subcutaneous closure after inguinal herniorrhaphy affects the operation time and immediate outcome of the wound. The study was aimed to assess the effects of a single layer closure of the skin and subcutaneous wound of inguinal herniorrhaphy, in contrast to the conventional two layer closure. DESIGN: Prospective randomized controlled trials. SETTING: Obafemi Awolowo University Teaching Hospital Ile-Ife, Osun State, Nigeria. PATIENTS AND METHOD: All adult patients attending surgical out patient clinic with uncomplicated inguinal hernia and had surgery, after randomization into two groups from June 2000 Dec 2005 were included in the study. One group had one layer - closure i.e. closure of skin and subcutaneous tissues together at once while the second group had two layer closure i.e. closure of skin and subcutaneous tissues separately. Duration of operation and complications were documented for comparison. RESULTS: One hundred and eighty wounds were studied in 160 patients; the extra wounds being from bilateral inguinal hernias. There were 93 wounds in group one (two layer closure) and 87 wounds in group two (one layer closure. There was no significant difference between healing of wounds and appearance of scars in both groups. The single layer closure group was, however, apparently quicker. (P= 0.006). CONCLUSION: The immediate outcome of the wound in both groups was similar. The medical personnel time was saved by closing the wound in single layer.

Abdominal tuberculosis in a Nigerian teaching hospital.

Abdominal tuberculosis (TB) alone or with disseminated TB is known to mimic other conditions with non-specific investigation findings. This study aims to evaluate the clinical presentations and investigation findings of patients in our setting. The clinical records of 47 patients diagnosed as abdominal TB between January 1986 and December 2005 at the Wesley Guild Hospital Unit of the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria, were reviewed. Fifty-five percent of the patients were women and mean age was 28 years. Common presenting symptoms and signs were abdominal pain 76.6%; ascites 59.6%; weight loss 53.2%; fever 29.8%. Average duration of symptoms before presentation was 3 months. Thirteen percent of patients had earlier been treated for pulmonary tuberculosis in the hospital. ESR was elevated in 89%, ultrasound scans of abdomen were abnormal in 68%, showing ascites, hepatomegaly and or enlarged nodes. Mantoux test was positive in 33% and ascitic fluid was diagnostic for TB in 29%. Chest X-ray showed abnormal findings in 25% of the patients and sputum was positive for AFB in 14.3%. Three patients were HIV positive. Forty patients (85.1%) recovered after receiving anti-TB drugs for a period of 9-12 months. Seven patients, including the three with HIV infection died. Death of 2 patients was due to unrelated causes. We conclude that abdominal TB should be suspected in patients with chronic abdominal condition and ascites as no laboratory or radiological finding is gold standard in its diagnosis. However the condition carries good prognosis if promptly diagnosed and treated.

Pattern of intestinal obstruction in a semiurban Nigerian hospital.

INTRODUCTION: Intestinal obstruction remains one of the commonest causes of acute abdomen worldwide. The pattern of intestinal obstruction varies from one place to another. We report the pattern of intestinal obstruction observed in a semi urban Nigerian hospital over a 5 year period. MATERIALS AND METHODS: Records of patient admitted and managed for intestinal obstruction between April 2001 and April 2006 at the federal medical centre, Owo, Southwestern Nigeria, were reviewed. Demographic data as well as parameters relating to the symptoms, duration, onset, type, diagnosis, intraoperative findings, as well as postoperative outcomes were retrieved. All data was entered into a personal computer and analyzed using SPSS for windows version 11. RESULTS: A total of 95 patients were managed during the period. The mean age was 39 years. The male:female ratio was 1.8:1. Adhesive intestinal obstruction was the commonest cause of symptoms in 44%, followed by volvulus in 14% and external hernias in 11% of the patients. A correct preoperative diagnosis was made in over 70% of the patients. Out of those with adhesive obstruction, 75% had a previous abdominal or groin operation while 57% had surgical exploration for failed conservative management. The mean duration of hospital stay was 6 days and the overall mortality rate was 20%. CONCLUSION: Adhesive intestinal obstruction is the commonest cause in this semi-urban population which was studied. Obstructed hernia is becoming increasingly less common as a cause of intestinal obstruction.

Correlation between endoscopic suspicion of gastric cancer and histology in Nigerian patients with dyspepsia.

Gastric mucosal biopsies of 77 dyspeptic patients whose endoscopic features were suggestive of cancer and 56 patients with uncomplicated duodenal ulcer (DU) were subjected to histopathological analysis. Gastric cancer was confirmed in 18 (23.4%) of the 77 patients but not in 59 (76.6%). 4 (5.2%) of the 18 patients had early gastric cancer (EGC). Histopathological findings in the stomach biopsy of the 59 patients in whom cancer could not be confirmed were compared with those of the 56 patients with DU. Intestinal metaplasia (IM) was present in 32.2% of the 59 cases with endoscopic suspicion of gastric cancer and in 16.1% of the 56 DU controls (P < 0.05). Mucosa-associated lymphoid tissue (MALT) occurred in 28.8% of the cancer-resembling cases and in 12.5% of the DU patients (P < 0.05). The difference in the prevalence of gastric mucosal atrophy and Helicobacter pylori infection between the two groups (83% vs. 71.4%) did not reach statistical significance (P > 0.10). All 18 patients with gastric cancer were positive for Helicobacter pylori and the prevalence of the infection approached 95% in those with IM and MALT. This study shows that IM and MALT present with endoscopic appearances that resemble that of gastric cancer and that along with the latter, their main aetiological agent is Helicobacter pylori.
