Mesocolic hernia, a case series.

ABSTRACT

INTRODUCTION AND IMPORTANCE Paraduodenal hernias are difficult to diagnose due to their unusual presentation. Herein, five new cases are added to the literature. CASE PRESENTATION Four male and one female child complained of paraduodenal hernias, two on the right side and three on the left side. The intestinal part that herniated inside the hernia sac was also malrotated in four patients. One patient had Meckel's diverticulum with a herniated intestine. One infant had extrahepatic biliary disease, a single atrium, polysplenia, intestinal malrotation, and a left paraduodenal hernia. Exploratory labarotomy was done for reduction of the intestine, reorientation, and repair of hernia orifices. CLINICAL DISCUSSION: Paraduodenal hernia is a component of malrotation. Cautious dissection of the hernia orifice is required to keep away from injuries to the inferior mesenteric vein or left colic artery in the course of the restoration of the left paraduodenal hernia. Also, the superior mesenteric vessels may be injured in the course of the restoration of the right paraduodenal hernia. CONCLUSION: There is a correlation between the occurrence of PDH with malrotation. The diagnosis of malrotation can be made with an ultrasound abdomen; however, it is true that ultrasound cannot make a confirmed diagnosis in all patients. Once the diagnosis of a mesocolic hernia has occurred, surgical repair is mandatory by closure of the defect.
