Colon Interposition Graft for Corrosive Esophageal Stricture: Midterm Functional Outcome

Background

Corrosive esophageal stricture is a major cause of morbidity among Nigerians. In most cases, this follows accidental or parasuicidal ingestion of caustic sodium hydroxide solution (NaOH) often used in the local production of soaps. Various treatment modalities have been advocated for the treatment of esophageal stricture. In this study, we review the results of our adopted technique in the past 10 years for pedicled colonic interposition.

Methods

This is a retrospective study of 21 patients who underwent substernal isoperistaltic pedicled colonic interposition graft for management of corrosive esophageal stricture. The right colon was pulled up into the neck in all the patients without resecting the strictured esophagus.

Results

Long segment strictures and multiple strictures were the main indications for the procedure. The mean duration of the procedure was 339.6 ± 71.1 min. The average intraoperative blood loss was 673.1 ± 398.1 mL. There were two (9.5 %) hospital mortalities. Graft infarction (9.5 %), cervical fistulae (19.0 %), and reflux neo-esophagitis (14.3 %) were the main non-fatal complications. In the mid-term, dysphagia was completely relieved in a little over 84 % (16/19) of patients, while one patient (4.8 %) still experienced reflux neo-esophagitis requiring treatment. There was no case of gross regurgitation or nocturnal aspiration in the mid-term.

Conclusions

Although the use of pedicled colonic interposition graft offers a good mid-term functional outcome with relief of dysphagia, early postoperative morbidity is high. Graft infarction is the single most important factor for poor functional outcome and every effort must be made to prevent its occurrence.     

Socio-economic and geographic differentials in costs and payment strategies for primary healthcare services in Southeast Nigeria

The study explored socio-economic and geographic inequalities that exist in healthcare seeking, expenditures and methods of paying for healthcare. The study was conducted in two communities (one rural and urban) in Southeast Nigeria. A pre-tested questionnaire was administered to household heads or their representatives by trained interviewers. A socio-economic status (SES) index, together with urban-rural comparisons was used to examine the inequalities. The expenditures on healthcare and the proportions of respondents that used the different payment strategies were compared across SES quartiles and between the urban and rural areas. There were varying degrees of socio-economic and geographic inequalities in treatment expenditures, providers seen and payment modalities that were used. User fee without reimbursement was the commonest type of payment strategy, followed distantly by instalment payment. The two poorest quartiles were less likely to have used user fee and they mostly used instalment payment in the rural area. Logistic regression analysis showed that location was significantly and positively related to user fee but not to instalment payment. In conclusion, the poorest SES group and rural dwellers are the major sufferers of inequality and this could be mitigated through improved provision of primary healthcare services in rural areas and initiation of exemptions, vouchers and other pro-poor payment strategies for the poorest SES groups.     

Gunshot wounds: bullet caliber is increasing, 1998-2003

In 1999, Caruso reported data from the level 1 trauma center in Newark, New Jersey, documenting "...an ominous trend toward the use of larger caliber firearms in accidents, homicides and suicides." Those data were derived from measurements of bullets removed from our trauma patients and submitted to the Surgical Pathology laboratory from 1981 through 1997. We further document this trend with measurements of similar source bullets from 1998 through 2002. During the same time, we recorded mortality among gunshot wound victims treated at our trauma center. Bullets submitted to surgical pathology during the years 1998 through 2002 were measured with a millimeter rule to determine caliber or transverse diameter. A total of 367 bullets were studied in this 5-year period. Bullets deformed beyond measurability (approximately 22%) and shotgun pellets (< 5%) were excluded from our study. Bullet calibers were expressed in terms of mean plus or minus standard error (x +/- SE). Mortality figures were derived from analysis of medical records concerning the outcomes all victims of gunshot wounds (E 922, E 965) treated at our hospital during the years studied and expressed as percentages. Linear regression of mean bullet caliber over time was performed, and analysis of variance was used to assess statistical significance of apparent differences in mortality. Bullet caliber continued to increase from 8.47 +/- 0.22 to 9.16 +/- 0.15 mm during the 5-year observation period. Linear regression reveals R = 0.9649, P < 0.01. Mortality ranged from 4.7 per cent to 10.7 per cent but the differences were not significant (P > 0.20). These data support a continued trend toward the use of larger caliber firearms in accidents, homicides, and suicides. Mortality does not change during this time and presumably because of improvements in treatment, from resuscitation to definitive surgery and its convalescence.     

How do health workers and community members perceive and practice community participation in the Bamako Initiative programme in Nigeria? A case study of Oji River local government area

The objective of this study was to assess the perceptions and practices of health workers and households in relation to community participation in the Bamako Initiative programme (BI). The study was conducted in Oji River local government area of South-East Nigeria where the BI program has been operational since 1993. A pre-tested questionnaire was used to collect information from 20 health workers charged with operating the BI in 20 health centres. In addition, focus group discussions were conducted with members of the district and village health committees. Community participation from both health worker and community perspectives seem to have been enhanced by the introduction of BI, despite some constraints. However, the communities were not involved in core areas of community participation, and the health workers seem to be resisting their participation fully. It is concluded the community participation in BI could be improved if expectations were made explicit. This improvement should take into consideration the desires and priorities of the communities and issues impeding participation should be addressed.     

Who buys insecticide-treated nets? Implications for increasing coverage in Nigeria

OBJECTIVES: To investigate the determinants of purchase of insecticide-treated nets (ITNs) and explore the policy implications of the findings for ITN programmes. METHODS: Two surveys were conducted 1 month apart in three villages. The first survey was used to determine stated willingness to pay (WTP) and respondent practices regarding untreated nets and ITNs. The second survey was accompanied by actual sales of ITNs. Pre-tested interviewer-administered questionnaires using three contingent valuation method (CVM) question formats, namely the bidding game (BG), binary with follow up (BWFU) and a structured haggling technique (SH), were administered to different sub-samples of the respondents. The nets were sold at a price of 350 Naira (US dollars 1 = 110 Naira). Bivariate analysis and logistic regression were used to investigate the factors that explain actual WTP. FINDINGS: While 15/158 (9.5%), 21/166 (12.7%) and 35/144 (24.3%) of the respondents in the BG, BWFU and SH stated WTP amounts that were equal to or greater than the price of the net, 19.6%, 24.7% and 24.3% of respondents actually purchased the nets in the three groups respectively. Lower socioeconomic groups were less likely to purchase the nets, while households with a recent attack of malaria and those that stated higher WTP amounts were more likely to purchase nets. Stated WTP was positively associated with actual WTP (p < 0.01). Increased distance of the respondents to the ITNs sales point decreased net purchases (p < 0.05). CONCLUSIONS: Stated WTP was a good predictor of actual WTP. ITNs distribution strategies that will decrease time and travel costs to households are needed to increase net coverage. Also, ITNs financing mechanisms are needed that will ensure that lower socioeconomic groups and those at greater risk of malaria are protected. Governments and donors should take the lead to ensure that ITNs programmes are equitable.     

Preferences for benefit packages for community-based health insurance: an exploratory study in Nigeria

Background  

It is important that community-based health insurance (CBHI) schemes are designed in such a way as to ensure the relevance of the benefit packages to potential clients. Hence, this paper provides an understanding of the preferred benefit packages by different economic status groups as well as urban and rural dwellers for CBHI in Southeast Nigeria.
