[Detection rate of Helicobacter pylori and its clinical significance in children with Meckel's diverticulum].

OBJECTIVE: To determine the detection rate of Helicobacter pylori (Hp) in children with Meckel's diverticulum (MD) and its clinical significance among children with MD. METHODS: Eighty-one children with MD were divided into two groups according to the presence (n=45) or absence (n=36) of digestive hemorrhage. The detection rates of Hp in MD tissues and stomach tissues were determined by immunohistochemistry. The detection rates of Hp were compared between the two groups and between the MD tissues with different clinical features in the hemorrhage group. RESULTS: The detection rate of Hp in MD tissues for the hemorrhage group was 76% (34/45), which was significantly higher than that for the non-hemorrhage group (47%, 17/36) (P<0.05). The detection rate of Hp in stomach tissues for the hemorrhage group (87%, 39/45) was insignificantly higher than that for the non-hemorrhage group (67%, 24/36) (P>0.05). Among patients in the bleeding group, the detection rate of Hp in MD tissues showed no relationship with age, sex, preoperative hemorrhage frequency, amount of hemorrhage, length of MD, basal diameter of MD, and pathological type (P>0.05), but was related to location of MD, presence or absence of ulcer, and depth of ulcer (P<0.05). For the hemorrhage group, a significant positive correlation was found between the detection rates of Hp in MD tissues and stomach tissues (P<0.05), as shown by the Spearman correlation analysis. CONCLUSIONS: The detection rate of Hp in MD tissues is increased in children with MD complicated by digestive hemorrhage. Hp infection may play some role in the hemorrhage process among children with MD.

[Logistic regression analysis of high-risk factors for neonatal incarcerated hernia with intestinal necrosis].

OBJECTIVE: To investigate the high-risk factors for neonatal incarcerated hernia with intestinal necrosis by logistic regression analysis. METHODS: Retrospective analysis was performed on the clinical data of 131 neonates with incarcerated oblique inguinal hernia containing the intestine. Of the 131 cases, 14 suffered from intestinal necrosis. The high risk factors for neonatal incarcerated hernia with intestinal necrosis were determined by logistic regression analysis. RESULTS: Manual reduction after incarceration (>2 times) (χ2 = 69.289, P<0.01), incarceration history (>2 times) (χ2 = 84.731, P<0.01), and mesentery incarceration (χ2 = 80.233, P<0.01) were the high-risk factors for neonatal incarcerated hernia with intestinal necrosis. CONCLUSIONS: Intestinal necrosis tends to occur in neonates with incarcerated hernia who have incarceration or received manual reduction more than twice and suffer from mesentery incarceration. Manual reduction is prohibited for these cases, which should be surgically treated immediately.
