Internal hernia complicated by volvulation and ischemia. Review of clinical findings and CT signs.

Resumen Las hernias internas son una causa rara de dolor abdominal agudo y obstrucción intestinal, que se producen por la protrusión de un asa intestinal por una apertura normal o anormal del peritoneo o del mesenterio. Es más frecuente en pacientes con antecedentes quirúrgicos o traumatismos intraabdominales. Pueden complicarse con cuadros de isquemia intestinal y perforación, con alta tasa de mortalidad, por lo que es de gran importancia su diagnóstico precoz. Presentamos el caso de una mujer sin antecedentes personales de interés, que acudió a urgencias con dolor abdominal inespecífico y leve repercusión analítica, siendo diagnosticada de hernia interna complicada con volvulación de asas de intestino delgado e isquemia intestinal.

Internal hernia through dual defects: defects in transverse mesocolon and lesser omentum a rare presentation: case report

Internal hernias have the potential to cause small bowel obstruction. Congenital internal hernias are impossible to diagnose clinically and radiologically in asymptomatic patients. We presented a case of 36 years male with complaints of pain abdomen abdominal distension and vomiting, contrast-enhanced CT showed an internal hernia with small bowel obstruction. On exploration, small bowel loops were identified near the lesser curvature and they are congested an edema was present, a defect of 5×1 cm was identified in the transverse mesocolon and was managed by reducing the hernia sac and closure of the defect in the mesentery of the transverse colon. If the intervention was delayed internal hernia might lead to ischemia, gangrene increasing morbidity and mortality. Early intervention is the key to decrease morbidity and mortality.

Case Report: Right paraduodenal hernia – a unique case of rare internal hernia presenting as acute small bowel obstruction

Paraduodenal hernia, a rare internal hernia, is an uncommon cause of small bowel obstruction. We present a case report of a 45-year-old male presenting to the emergency department with complaints suggestive of small bowel obstruction. Abdominal plain X-ray was also suggestive of small bowel obstruction. Emergency laparotomy showed intraoperative findings of right sided paraduodenal hernia with dilated small bowel. Postoperative hospital stay was uneventful and the patient was doing well during 24 months of follow up with no active complaints. Paraduodenal hernia should be considered as part of the differential diagnosis of small bowel obstruction in patients who have repeated attacks and no prior history of abdominal surgery. Surgeons need to have an astute clinical acumen in diagnosing internal hernias to avoid repercussions and fatal events.

P-B03 Gastric Band Tubing Causing Small Bowel Obstruction

Background Laparoscopically adjustable gastric bands (LAGB) have been widely employed as a means of weight loss in bariatric surgery over the past two decades. Although now largely superseded by other bariatric surgical techniques, complications from gastric bands continue to be encountered in surgical practice. We report an unusual case of small bowel obstruction due to an internal hernia caused by gastric band tubing resulting in closed loop small bowel obstruction. This is not commonly encountered and emergency general surgeons need to have a high index of suspicion for this condition as a possible cause for small bowel obstruction. Methods A 40 year old male presented with abdominal pain, vomiting and failure to open bowels or pass flatus for nine days. Twelve years previously (2008) he had had Roux n Y gastric bypass (RYGB), followed by by laparoscopic gastric banding of the RYGB about two years later (2010) also in the private sector. He had a soft but distended abdomen, and empty rectum on rectal examination. CT scan abdomen reported as: Multiple loops of distended small bowel demonstrated. No air seen in rectum, indicative of small bowel obstruction. No pneumoperitoneum. There is dilatation of the mid and distal small bowel seen to an apparent transition point in the mid abdomen where a loop is noted associated with the tubing for the inflation device for the gastric band. This appears to be centred on the cause of obstruction and appears tied around the base of mesentery and may be creating a closed loop obstruction, by having created an internal hernia. This patient had an internal hernia around loop of the gastric band tubing with resultant closed loop small bowel obstruction. The patient underwent diagnostic laparoscopy with ileo-caecal resection and primary anastomosis. He made successful recovery. Deflated gastric band remains in-situ. Results While small bowel obstruction is most commonly due to adhesions in individuals who have had previous laparotomy, it is important to bear in mind other causes such as internal hernias particularly in cases of those with history of previous gastric banding or Roux n Y gastric bypass. Early intervention may be necessary to reduce the likelihood of bowel ischaemia and bowel resection. Laparoscopy is a useful tool in the management of small bowel obstruction.
