Left mesocolic hernia (syn – left paraduodenal hernia/hernia of Landzert) is a type of internal hernia which occurs due to malrotation of the midgut and forms a potential space near the ligament of trietz. Prompt diagnosis is crucial to prevent strangulation. We report a rare case of left mesocolic hernia presenting as internal Maydl's hernia complicated by jejunal volulus, presenting as acute abdomen. An emergency derotation and reduction of small bowel was done with repair of the defect.

| Introduction|| |
An internal hernia is protrusion of the viscera through an opening in the mesentry or peritoneum. Internal hernia of the small bowel is a relatively rare cause of intestinal obstruction and accounts for less than 2% of all causes. Mesocolic hernia (paraduodenal hernia) is a type of internal hernia. We report a rare case of left mesocolic hernia presenting as internal Maydl's hernia complicated by jejunal volvulus, without strangulation.
| Case Report|| |
A 55-year-old female presented with diffuse pain in the abdomen of 1 week duration which had increased in intensity since 1 day. Pain was associated with vomiting which was nonbilious and the patient had no bowel movement since 2 days. She had a history of bilateral tubectomy 30 years back and abdominal hysterectomy 18 years back. She is a known case of type 2 diabetes mellitus, on regular medication with well-controlled blood sugars. On examination, her temperature was normal, pulse rate was 90/min, and blood pressure was 110/90 mmHg. Heart and lungs were clinically normal. Perabdominal findings revealed distention of the abdomen with tender ill-defined mass in the left lumbar and umbilical regions. The patient's routine investigations were normal. Plain erect abdomen X-ray revealed distended small bowel loops. Computed tomography (CT) scan of the abdomen revealed loops of dilated small intestine at jejunoileal junction possibly volvulus in the anticlockwise direction at the jejunoileal region.
A globular hernial sac of approximately 25 × 25 cm was noted containing jejunum [Figure 1] and [Figure 2]. The inferior mesenteric vein was traversing vertically across the oval-shaped neck of the sac, placed anteriorly in relation with the neck of the sac [Figure 3] and [Figure 4]. Jejunal volvulus was seen in the anticlockwise direction protruding from the neck of the sac. The afferent loop being the proximal jejunum and the efferent loop being the distal jejunum posterior to the inferior mesenteric vein. A mid jejunal loop arising from the sac was protruding through the small defect behind the inferior mesenteric vein presenting as internal Maydl's hernia complicated by volvulus.

A vertical incision was given on the anterior wall of the sac approximately 5 cm from the anterior edge of the neck of the sac, thereby facilitating to undo the volvulus of the jejunum, as also to pull the contents (jejunum) of the sac underneath the inferior mesenteric vein, hence restoring normal anatomy, from the duodenojejunal flexure to jejunoileal junction. The cut medial aspect of the sac was wrapped anterior to the inferior mesenteric vein and sutured to the left leaf of the proximal jejunal mesentry, thus obliterating the defect. The redundant sac (left lateral part) was closed with capitonnage. A tube drain was placed in the left paracolic gutter and the abdomen was closed in layers [Figure 4].
| Discussion|| |
Mesocolic hernias are one of the cause of internal hernias, with left paraduodenal hernia (hernia of landzert) three times more common than right paraduodenal hernia (Waldeyer's hernia). These hernias occur due to malrotation of the midgut. Alternatively, a genetic etiology has been suggested given the association between transmesenteric hernia and other anamolies including cystic fibrosis and hirschprung disease.
Anatomical consideration of left mesocolic hernia
The left mesocolic hernia represents a herniation of the small intestine into fossa near the fourth part of the duodenum. The paraduodenal fossa (of Landzert) is most often incremented. The superior portion of this fossa is rimmed by inferior mesenteric vein.
The symptoms are quiet variable varying from mild abdominal cramps or occasional vomiting to acute intestinal obstruction. Postprandial pain with postural variation is a characteristic symptom. Inferior mesenteric vein compression in left paraduodenal hernias may lead to hemorrhoids. Internal hernia may be complicated by gangrenous bowel, perforation, or volvulus.
CT is the imaging modality of choice in diagnosing a mesocolic hernia. A CT scan here demonstrates clustering of loops of small bowel at or above the ligament of treitz.,,
Timely surgical intervention is necessary, due to very high probability of incarceration or strangulation during life time. An exploratory lapratomy with reduction of hernia and closure of the defect is advised in case of obstruction.
There is controversy regarding whether an asymptomatic paraduodenal hernia incidentally found at operation for another cause should be reduced. Serious surgical errors have been made at laparotomy, for example, gastroileostomy, when the presence of a paraduodenal hernia was not appreciated.
| Conclusion|| |
We report a rare case of left mesocolic hernia presenting as internal Maydl's hernia complicated by jejunal volvulus, without strangulation.
An early diagnosis and exploratory laparotomy has prevented morbidity and mortality in this patient. The insidious onset of this surgical emergency reaffirms the importance of surgeons maintaining a high index of suspicion for a transmesenteric hernia in patients with nonspecific clinical and radiological signs.
