    ABSTRACT: Incisional hernias (IH) represent a breakdown or loss of continuity of a fascial closure. They are thus unique as the only external wall hernias that are iatrogenic in aetiology. Incisional hernias are not uncommon complications of laparotomy closure with reported incidence of 2 to 11%. To review our experience,with incisional hernaia identify possible risk factors and proffer preventable strategies. All case records of adult patients managed with IH at the University of Maiduguri Teaching Hospital between January 1995 and December 2004 were retrieved from the Medical Records Department. Relevant data on age, sex, type and institution of index surgery (General Hospital or Private Hospital), premorbid factors, type of repair, post-operative complications were extracted. Case records with inadequate information were excluded. Between January 1995 and December 2004 a total of 440 patients with external abdominal hernias were treated at UMTH. Out of these: 38 (11.6%) were Incisional hernias and form the basis of this study. Their ages ranged between 18 and 80 years, with peak age range of 40-49 years. There were 6 males and 32 females giving a male to female ratio of 1:5.3. The commonest index surgeries were caesarean section in 12 patients (31.6%) and appendicectomy 10 patients (26.3%). Of the index surgeries 26 (68.4) and 10 (26.3) were performed in general and private hospitals respectively. Only 2(5.3%) were done at UMTH. Wound sepsis, in 18 patients (47.4%), postoperative cough, 8 (21.1%) and obesity 6 (15.8%) were the commonest risk factors. Poor surgical technique was found in 36 patients (94.7%) Most of the patients presented late; 8(21.1%) with recurrence and 6(15.8%) were giant in size. All but one were successfully repaired. Only one (2.3%) had recurrence. There was no mortality. Incisional hernias are not uncommon constituting 11.6% of all adult external abdominal wall hernias repaired at UMTH. Most of the causes are preventable with 94.7% of the index surgery done at peripheral hospitals where poor surgical technique was common to all. There is urgent need to re-train our general duty doctors on proper surgical techniques of abdominal wound closure.

    ABSTRACT: Enterocutaneous fistula (ECF) remains an important surgical problem with significant morbidity and mortality. This study aims to review the aetiology and management outcome in a depressed economy like ours. A retrospective review of 54 patients with ECF admitted into the surgical wards of the University of Maiduguri Teaching Hospital (UMTH) between January 1994 and December 2004 (11 year period). Thirty two (59.3%) were males and 22 (40.7%) were females giving a male/female ratio of 1.5 to 1. The age ranged from 1 to 58 years with two peak incidents of 20-29 years and 40-49 years. Eighteen cases (33%) occurred following appendicectomy, 12 (22%) following laparotomy for intestinal obstruction, 10 (18.5%) following laparotomy for abdominal malignancies, 7 (13%) followed laparotomy for penetrating abdominal injuries, 3 (5.5%) followed laparotomy for perforated typhoid enteritis, 2 (3.7%) cases were due to spontaneous rupture of strangulated and neglected inguinal hernia, 1 (1.9%) case followed chest tube insertion for pleural effusion in a PTB patient and 1 (1.9%) case followed a native healer's incision on a lumber hernia. Altogether,45 (83.3%) were referred cases from peripheral hospitals. Fourty one (76%) were high output type, while 13 (24%) were low output type. Most patients 32 (59.3%) healed spontaneously on conservative management. Eighteen (33%) had surgical intervention. Eight patients demised giving a mortality rate of 15%. The average hospital stay was 56 days. The main cause of ECF in our environment is postoperative (94.4%) with post appendicectomy cases alone accounting for 33%. Majority of our patients (66.7%) were managed conservatively.

    ABSTRACT: Cancer of the gall bladder is an uncommon but highly lethal disease associated with cholelithiasis and chronic cholecystitis in occurrence. A report of three cases seen over six years at the University of Maiduguri Teaching Hospital (UMTH) is presented together with a review of the literature. Three cases were seen over a period of 6 years. There were two females and one male. The patients were aged 80, 50 and 65 years respectively. The 80 year old man and 50 year old female presented with right hypochondrial mass and pain. The third presented with features of multiple metastases involving the liver and omentum. The first two cases had cholecystectomy and limited resection of adjacent liver tissue. The third case had unresectable cancer with gross involvement of the liver, peritoneum and omentum; she died three weeks after exploratory laparotomy. Cancer of the gall bladder is rare in this environment. A high index of suspicion in addition to ultrasound and computerized tomography helps in making an early diagnosis. This may improve the outcome of management.

    ABSTRACT: A total of 21 cases of severe burns in pregnancy managed at the University of Maiduguri Teaching Hospital, Maiduguri, over a 10-year period, spanning January 1991-December 2000 inclusively were reviewed. The pregnancy loss was 92.9%, with the pregnancies spontaneously terminated within 10 days of sustaining the injury. Maternal mortality was 47.6% with sepsis as the most common cause of death. It is advocated that viable pregnancies should be terminated as soon as the mother is resuscitated following severe burn injury. Prophylactic systemic antibiotics should be given to minimise the development of sepsis. Patients are best managed in the obstetrics ward during the first 2 weeks of injury. A multidisciplinary approach is encouraged in managing cases of severe burns in pregnancy.

    ABSTRACT: We present two patients to highlight an emerging trend of suicide attempts presenting to the surgeons with penetrating abdominal injuries found to be HIV/AIDS related. The two patients were managed at the University of Maiduguri Teaching Hospital in the year 2003. Both patients presented as emergencies with penetrating abdominal injuries and were resuscitated followed by clinical evaluation and laparotomy. Both patients had visceral injuries that were repaired at laparotomy and were both confirmed HIV positive. There is an emerging trend of suicide attempts in HIV/AIDS patients and the need to determine the suicide pattern that will enable all stakeholders workout a formidable HIV/AIDS and suicide prevention programmes.

    ABSTRACT: There is increased tendency towards double-gloving by general surgeons in our practice, due probably to awareness of the risk of contamination with blood or other body fluids during surgery. The aim of the study was to compare the relative frequency of glove puncture in single-glove versus double glove sets in general surgical procedures, and to determine if duration of surgery affects perforation rate. Surgeons at random do single or double gloves at their discretion, for general surgical procedures. All the gloves used by the surgeons were assessed immediately after surgery for perforation. A total of 1120 gloves were tested, of which 880 were double-glove sets and 240 single-glove sets. There was no significant difference in the overall perforation rate between single and double glove sets (18.3% versus 20%). However, only 2.3% had perforations in both the outer and inner gloves in the double glove group. Therefore, there was significantly greater risk for blood-skin exposure in the single glove sets (p < 0.01). The perforation rate was also significantly greater during procedures lasting an hour or more compared to those lasting less than an hour (p < 0.01). Double-gloving reduces the risk of blood-skin contamination in all general surgical procedures, and especially so in procedures lasting an hour or more.

    ABSTRACT: Violent assault injuries are a frequent occurrence in the native communities of the North Eastern Nigeria. The injuries are mostly unreported, and therefore no policy towards prevention. We hope to highlight the common causes and pattern of such injuries, as well as suggest control measures in order to reduce the incidence. A retrospective review of 208 assault injury cases seen at the Accident and Emergency department of the Federal Medical Center, Nguru, between January 2002 and December 2006. All but 12 were males, giving a male to female ratio of 16:1. Most of the patients are illiterate herdsmen and farmers. The age ranged from 12 to 70 years, with a mean of 30.9 +/- 11.2 years. The peak age incidence was 30-40 years. Fighting was the most common cause, accounting for 124 (59.6%), followed by armed robbery assaults, which accounted for 75 (36.1%). Domestic abuse was the cause in 9 cases (4.3%). Arrow shot was the commonest form of assault injury in 55 (26.4%) cases, followed by matchet in 49 (23.6%), gunshot in 37 (17.8%), club/stick in 32 (15.4%) and stab wounds in 26 (12.5 %). Quarrel over farmlands used for grazing by herdsmen was the leading cause of fighting resulting in assault injuries (87), followed by quarrel over women (32)! Assault injuries are a common occurrence in the native communities of the North Eastern Nigeria. Addressing the root causes such as mapping out grazing lands in the region, community policing as well as mandatory reporting of all assault injuries to the police for appropriate legal action, will help reduce the incidence of assault injuries.

    ABSTRACT: Background: Typhoid fever is still a serious health burden in our environment. Though it is primarily a medical problem, its complications such as perforation require the attention of the surgeon. The disease spears no age or sex; including pregnant women. Four patients with pregnancy and pregnancy related conditions were managed during this period of review and this actually stimulated this study. Method: This is a retrospective study of all patients managed for typhoid perforation over a five-year period in University of Maiduguri Teaching Hospital. Results: Four hundred and sixty-seven patients were managed for typhoid fever in University of Maiduguri Teaching Hospital during the 5-year study period. Forty-three (9.2%) of these patients had typhoid perforations. There were six (14%) deaths among those patients with perforations. High rate of mortality was noted among those with pregnancy and pregnancy related perforations (50%) and multiple perforations requiring resection and anastomosis (100%). Conclusion: The morbidity and mortality associated with typhoid fever in our environment can only be reduced significantly when the nation and public health officials begin to pursue the principles of primary health care with all seriousness it deserves i.e. emphasis on provision of potable water supply and sanitation.
