Background: The use of honey as an escharotic agent in the conservative management of omphalocele major has not been widely explored in spite of its proven benefits in chronic wound management. We explored the use of local honey as an escharotic agent by comparing its use with 2.5% formal saline in the conservative management of major omphaloceles at the Lagos University Teaching Hospital, Lagos, Nigeria. Methods: From January 2006 to December 2009, 43 consecutive newborns with intact omphalocele major were alternately assigned into either Honey (H) or formal saline (FS) group. The membrane cover of each omphalocele was painted with the allotted group agent once every 48 h. The occurrence of faecal fistulas, rupture of eschar, intestinal obstruction as well as the mean duration of full wound healing, infection rates and overall mortality rates were compiled for the two groups. Results: Eighteen newborns were assigned to the FS group while 25 others were prospectively enrolled into the H group. The age, sex and weight of newborns in both groups at presentation were comparable. Three omphaloceles (16.7%) ruptured and eviscerated among the FS group during the study while 1 (4%) of these occurred in the H group. Four (22.2%) cases of faecal fistula occurred in the FS group while none was recorded in the H group. One (5.6%) patient in the FS group developed small bowel stricture. This was not recorded in the honey group. Overall, there were 8 (44.4%) complications in the FS group and 1 (4%) in the H group. There was no statistical difference between the two groups concerning the occurrence of fistulae, sac rupture or bowel stricture. However, overall number of complications was statistically more in the FS group when compared to the H group (P < 0.05). Wounds in the H group healed within a mean period of 34.4 ± 4.9 days while those in the FS group healed within a mean period of 45.7 ± 6.8 days P < 0.01). Conclusion: Honey is a good escharotics agent in the conservative management of major omphaloceles. Honey promotes faster healing and unlike 2.5% formal saline, is not significantly associated with faecal fistulas, rupture or bowel stricture.

| Introduction|| |
Omphalocele is the congenital herniation of abdominal contents into the base of the umbilical cord through an abdominal wall defect covered by a sac composed of amnion, Wharton's Jelly and peritoneum. It constitutes one of the most common forms of anterior abdominal wall defect with an incidence of 3000 cases per live births. For treatment purposes, omphaloceles are classified as major and minor, based on the size of the fascial defect.
The treatment options available depend largely on the size of the fascial defect and the presence of other congenital anomalies. Those with the small defect are managed by the primary fascial closure. Larger defects may be managed by excision of the sac and staged reduction of the hernia content with a spring-loaded silastic silo before closure within 1–2 weeks to avoid the risk of the abdominal compartmental syndrome. Such aggressive management of major omphaloceles requires mechanical ventilator support and total parenteral nutrition, often unavailable in resource-challenged third world settings. The use of escharotic agents to promote contraction and epithelisation has been widely reported with Mitul and Ferdous reporting a survival rate of 85% in their study. A delayed repair is later performed for the resultant ventral hernia. Many escharotics agents such as mercurochrome, methylated spirit and silver sulphadiazine have been employed for the initial management of major omphaloceles, with the aim of toughening the flimsy, non-living, protein-rich covering-membrane into a waterproof eschar under which granulation tissue may proliferate and eventually epithelise. At the Lagos University Teaching Hospital, we had conventionally used a 2.5% formal saline (FS) preparation from our Pharmacy Department as escharotics. We have used honey for the management of other open wounds and have heard anecdotal reports of its use for omphaloceles. These prompted us to explore the possibility of employing this agent in the management of major omphaloceles and comparing it with our traditional use of FS.
| Methods|| |
This was a cross-sectional analytical study that took place at the Lagos University Teaching Hospital. Ethical clearance was obtained for this study from the Hospital's Research Ethics Committee.
All newborns with intact omphalocele major (fascial defect >5 cm) admitted into our service over 4 years period were alternately assigned into either Honey (H) or FS group.
Excluded were cases of minor omphalocele which were primarily repaired, ruptured omphaloceles, grossly septic sacs, babies with omphaloceles from non-consenting parents and babies with life-threatening, co-existing gross pathologies such as severe cardiac defects.
Bio-demographic details such as gestational age at delivery, birth weight and gender were obtained for each patient as well as the age at presentation. Clinical assessment of the patients included a systemic examination of the respiratory and the cardiovascular systems were performed to identify other co-morbidities. The membrane cover of each omphalocele was painted with the allotted group agent daily and was left open under a tent of insect-proof netting. The progressive separation of eschar from underlying granulation tissue was noted daily. Mean duration of full healing, the occurrence of faecal fistulas, rupture of eschar, intestinal obstruction and overall mortality rates were compiled for the two groups.
A restraining plaster cast was applied to the lower limbs to prevent the baby from kicking and rupturing the membrane in the early stages before the eschar had fully hardened. Oral feeding was commenced when alimentary continuity was assured. Each baby was treated with a 10-day course of augmentin (25–50 mg/kg/day) and multivitamin syrup. All the babies were admitted and treated on the same ward by the same group of nursing and medical staff. The data collated were analysed using SPSS software version 16 (SPSS Inc. Released 2007. SPSS Statistics for Windows, Version 16.0. Chicago, USA, SPSS Inc.).
| Results|| |
Forty-three newborns were treated in the period under review. There were 24 (55.8%) males and 19 (44.2%) females, giving a male: Female ratio of 1.3:1. The age at presentation ranged from 1 to 8 days, with a mean age of 2.0 ± 1.4 days. Thirty-nine (90.7%) of the babies presented within the first 72 h of life, whereas the remaining 4 (9.3%) had been taken to other hospitals before presenting between 4–8 days. Eighteen newborns were assigned to the FS group while the remaining 25 were prospectively enrolled into the H group. The gender and age at presentation did not significantly differ between the FS and H groups.
Eschar separation from underlying granulation tissue
Separation of eschar from underlying granulation tissue occurred from 22 to 34 days in the FS group, with a mean of 29.9 ± 3.7 days. In the H group, the same occurred from 13 to 29 days, with a mean of 21.8 ± 5.7 days. The H group thus experienced a significantly earlier separation of eschar when compared to the FS group (P = 2.28−8).
Mean duration of full healing
Wounds in the H group healed within 27–45 days with a mean period of 34.4 ± 4.9 days while those in the FS group healed within 31–63 days with a mean period of 45.7 ± 6.8 days. Wounds in the honey group healed significantly earlier than the FS group (P = 0.0002). [Figure 1] and [Figure 2] showed patient whose omphalocele was managed with honey.

Sac rupture, Faecal fistula, Bowel stricture
Three omphaloceles (7%) ruptured and eviscerated among the FS group during the study while 1 (2.3%) of these occurred in the honey (H) group. Four (9.3%) cases of faecal fistula occurred in the FS group while none was recorded in the H group. One (2.3%) patient in the FS group developed small bowel strictures. These were resected at laparotomy and end-to-end anastomosis performed with a good outcome. No stricture was recorded in the honey group. Overall, there were 8 (18.6%) complications in the FS group and 1 (2.3%) in the H group. Although there was no statistical difference between the two groups concerning sac rupture or bowel stricture, the application of FS was statistically significantly associated with fistula formation (P = 0.017). Further use of FS was thus suspended after the eighteenth case [Table 1].
Three babies died during the study. Two deaths resulted from faecal fistulas in the FS group and the third was from evisceration following a ruptured sac in the H group [Table 1] giving a mortality rate of 11.1% and 4%, respectively.
| Discussion|| |
Many agents have been used as escharotics in the conservative treatment of major omphaloceles. Mercurochrome, silver sulphadiazine, methylated spirit and povidone-iodine have been applied to the friable omphalocele sacs for this purpose., The medicinal properties of honey have been known since ancient times and its healing effects have been employed for wound care since antiquity. However, its use as an escharotic agent in the management of omphalocele has not been widely explored.
Our study revealed that the time of separation of eschar and the duration for complete epithelisation, converting the omphalocele sac to a ventral hernia was significantly shorter in the honey group than the FS group. A higher proportion of patients that were subjected to FS had their conditions complicated by bowel fistula and rupture of the sacs.
Nicoara et al. reported the first ever use of Manuka honey in the conservative treatment of five cases of major omphaloceles. In this retrospective analysis of a limited case series, the investigators concluded that honey was safe, efficacious and it promoted wound healing with a favourable outcome. No untowards occurrence was ascribable to the use of honey in their study. The median duration for the full epithelisation in their study was 63 days as against a mean of 34.4 ± 4.9, obtained in our study. Only five patients were recruited in Nicoara's study, and this could explain the difference witnessed.
Honey has been shown to possess some inherent properties that make it a good healing agent. It contains inhibin, a thermolabile, photolabile substance with antibacterial properties. It has a high nutrient content of fructose, sucrose, glucose, glucuronic acid and gluconolactone that combine to create an environment that promotes granulation tissue formation. Inhibin is essentially a composition of hydrogen peroxide, flavonoids and phenolic acid which results in shrinkage of bacterial wall. It also induces an unfavourable environment with a low pH level that further potentiates its antibacterial action. In over 500 reports on the clinical usage of honey, no serious untowards effect of honey was documented.
Although there is a paucity of literature on the use of honey in omphaloceles,, its use in other surgical settings such as burn wound management and open wounds have been widely documented. Subrahmanyam  found a higher rate in wound healing with the use of honey compared to silver sulphadiazine in a randomised controlled study. This finding is consistent with our study which revealed a comparatively shorter duration for full epithelisation than FS.
In a meta-analysis comparing the efficacy of honey in the management of burn wound with other conventional dressing agents and using the proportion of wound healed in 15 days as the outcome measure, Wijesinghe et al. in their study reported a greater efficacy in the management of superficial and partial thickness burn wound with honey when compared to other alternative dressing treatment. Similarly, Molan  in an analysis of the use of honey as a wound dressing, concluded that there was convincing evidence to support the use of honey for a wide range of wounds because of its antibacterial, anti-inflammatory properties as well as its ability to promote granulation tissue. Bangroo et al. also corroborated this finding in a review of the duration of healing of burn wounds in paediatric patients. The use of honey resulted in a shorter duration compared with sulphadiazine.
Limitation of the study
Bacteriological studies were not consistently available for the duration of this study. Moreso, we acknowledge that a major limitation of our study is the relatively small number of patients recruited and the alternate allocations of subjects into the study groups rather than following a randomisation schedule. Further work may thus be required on a much larger scale to generate a more statistically convincing outcome.
| Conclusion|| |
Honey is a good escharotic agent in the conservative management of major omphaloceles and compared to 2.5% FS, honey promotes rapid formation of granulation tissue and gentle separation of eschar. It is not associated with faecal fistulas, rupture or bowel stricture. The use of honey as an escharotic therefore deserves further exploration.
