Congenital left paraduodenal hernia causing chronic abdominal pain and abdominal catastrophe

Mesocolic hernia, a case series

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.

Large left paraduodenal hernia with intestinal ischemia: a case report and literature review

A left paraduodenal hernia is a rare type of internal hernia but the most common type of peritoneal recess hernia. Preoperative diagnosis of a left paraduodenal hernia is difficult because of its nonspecific clinical manifestations, and it is often confused with other causes of acute abdomen. Diagnosis is therefore often delayed, resulting in serious clinical outcomes. We herein report a case of a large paraduodenal hernia with small intestinal obstruction and ischemia without abdominal pain. The patient was successfully discharged after emergency hernia repair. This case reveals the importance of diagnosing a left paraduodenal hernia with or without abdominal pain, especially in patients with no history of abdominal surgery.

Left Paraduodenal Hernia: A Cause of Double Intestinal Obstruction

Paraduodenal hernias are of congenital origin and may present with symptoms and signs of small intestinal obstruction. These hernias are rare in our practice, and a definitive preoperative diagnosis is often not made as the symptoms are not specific. Early assessment and prompt and adequate resuscitation and surgery obviate the risk of strangulation and intestinal resection. This report highlights a rare cause of intestinal obstruction in a young male who presents with all the classical features of obstruction: colicky abdominal pain, distension, vomiting, and inability to pass stool or flatus. The diagnosis of paraduodenal hernia was made intraoperatively. We do not routinely request for barium examination or abdominal computed tomography scan in acute abdominal pain. These modalities can suggest a preoperative diagnosis.

Treitz Hernia: Report of a Case and Review of the Literature

INTRODUCTION

Congenital hernias are rare findings, and their diagnosis is often delayed due to an incorrect interpretation of the clinical symptoms and/or images. We present a rare case of left-sided paraduodenal hernia at the ligament of Treitz, followed by a review of the literature.

CASE PRESENTATION

We report the case of a 20-year-old patient with unusual, recurring abdominal pain in the past 3 months. There were no previous operations or past illnesses in the patient's history. The computed tomographic scan showed a misplacement of small bowel into the lesser sack. With high suspicion of an internal hernia, we performed a diagnostic laparoscopy, which revealed a Treitz hernia. The reduction and fixation could be carried out fully with minimally invasive surgery with an uneventful postoperative course and complete recovery.

CONCLUSION

A Treitz hernia is a rare cause of unspecific abdominal pain and the clinical signs are difficult to interpret. However, its knowledge may help to avoid emergency procedures and provide quick recovery of the patients. We recommend the laparoscopic approach as the first choice of treatment in all cases of internal hernia in the absence of peritoneal irritation or severe bowel obstruction.

Segmental volvulus in the neonate: A particular clinical entity

BACKGROUND

Complete intestinal volvulus is mainly related to congenital anomalies of the so-called intestinal malrotation, whereas segmental volvulus appears as a distinct entity, mostly observed during the perinatal period. Because these two situations are still lumped together, the aim of this study was to describe the particular condition of neonatal segmental volvulus.

STUDY DESIGN

We analyzed the circumstances of diagnosis and management of 17 consecutives neonates operated for segmental volvulus more than a 10-year period in a single institution. During the same period, 19 cases of neonatal complete midgut volvulus were operated.

RESULTS

Prenatal US exam anomalies were observed in 16/17 (94%) of segmental volvulus, significantly more frequently than in complete volvulus (p=0.003). Intestinal malposition was described peroperatively in all cases of complete volvulus, but also in 4/17 segmental volvulus (23%). Intestinal resection was performed in 88% of segmental volvulus when only one extensive intestinal necrosis was observed in complete volvulus. Parenteral nutrition was required in all patients with segmental volvulus with a median duration of 50days (range 5-251).

CONCLUSION

Segmental volvulus occurs mainly prenatally and leads to fetal ultrasound anomalies. This situation, despite a limited length of intestinal loss, is associated to significant postnatal morbidity.

TYPE OF THE STUDY

Treatment study.

Incarceration of Meckel's diverticulum in a left paraduodenal Treitz' hernia

Meckel’s diverticula incarcerated in a hernia were first described anecdotally by Littré, a French surgeon, in 1700. Meckel, a German anatomist and surgeon, explained the pathophysiology of this disease 100 years later. In addition, a congenital paraduodenal mesocolic hernia, known as a Treitz hernia, is a rare cause of small bowel obstruction. These hernias are caused by an abnormal rotation of the primitive midgut, resulting in a right or left paraduodenal hernia. We treated a patient presenting with pain and diagnosed extraluminal air in the abdomen after a computed tomography examination. We performed a laparotomy and found a combination of these two seldomly occurring congenital diseases, incarceration and perforation of Meckel’s diverticulum in a left paraduodenal hernia. We performed a thorough review of the literature, and this report is the first to describe a patient with a combination of these two rare conditions. We considered the case regarding the variety of terminology as well as the treatment options of these conditions.
