Internal hernia is defined as the herniation of viscera through an anatomic or pathologic opening within the boundaries of peritoneal cavity. Transmesocolic hernia, a subtype of internal hernia, has a herniated sac through the transverse mesocolon. Transmesocolic hernia has been rarely described in the literature, and most of reported cases were associated with a history of operation or congenital anormaly. A 72-year-old female with chronic intermittent abdominal pain and bloating was admitted. Small bowel series showed multiple jejunal loops confined to the left upper quadrant of abdomen. Abdomen spiral computed tomography (CT) showed a cluster of mildly dilated small bowel loops with mesenteries on the same area. On the three-dimensional reconstruction CT scan, a herniated sac through the transverse mesocolon was identified. She was diagnosed as transmesocolic hernia by using the three-dimensional reconstruction CT and small bowel series, without surgical exploration. The symptoms were managed with conservative measures.

Internal hernia is difficult to diagnose clinically because the symptoms are often non-specific. Although this entity is an uncommon cause of small-bowel obstruction, prompt diagnosis is essential for a favorable outcome. We report the barium, CT and MRI features of a rare case of non-obstructing combined transmesocolic and left paraduodenal hernia.

Internal hernia through a defect in the broad ligament is a rare cause of intestinal obstruction, and pre-operative diagnosis is generally difficult. Here, we report our experience in which multi-detector computed tomography (MDCT), which allows direct recognition of incarcerated small bowel, was useful in the pre-operative diagnosis of this hernia.

Internal hernia, the protrusion of a viscus through a peritoneal or mesenteric aperture, is a rare cause of small bowel obstruction. We report the clinical presentation, surgical management, and outcomes of one of the largest series of nonbariatric internal hernias. Ten-year retrospective review of patients at our institution yielded 49 cases of internal hernias. Majority of patients presented with symptoms of acute (75%) or intermittent (22%) small bowel obstruction. While 16% of CT scans were suspicious for internal hernia, in no cases the preoperative diagnosis of internal hernia was made. The most frequent internal hernias were transmesenteric (57.0%) and 34 hernias (69%) were caused by previous surgery. All internal hernias were reduced and the defects were repaired. Compromised bowel was present in 22 cases and 11 patients underwent small bowel resection. The mean postoperative hospitalization was 10.9 days. The overall mortality rate from our series is 2%, and the morbidity rate is 12%. Transmesenteric hernias, as complications of previous surgeries, are the most prevalent internal hernias. Preoperative diagnosis of internal hernia is extremely difficult because of the nonspecific clinical presentation. However, if discovered promptly, internal hernias can be repaired with acceptable morbidity and mortality.

Internal hernia is rare its frequency ranging between 0.6 and 5.8%. It results from the protrusion of one or more abdominal viscera (usually small bowel) through an intraperitoneal opening. The opening can be normal (e.g. Winslow foramen), congenital (paraduodenal fossa, ileocecal fossa), or abnormal anatomical entities (after trauma or surgery). The clinical diagnosis of internal hernia is difficult because of the lack of specific signs and symptoms. There is a 63.6% lifetime risk of strangulation and bowel ischemia. In such cases, computed tomography is essential in the preoperative diagnosis because of the high mortality rate (20%) (which justifies its costs).

Internal hernia is an unusual cause of intestinal obstruction, and the through sites of hernias may include the paraduodenum, transmesenteric region, foramen of Winslow, paracecum, the broad ligament of the uterus, and the transomental region. Transomental hernia is the rarest type of internal hernia and accounts for fewer than 1% of internal hernias. Transmesenteric and transomental hernias are different from the other types of internal hernia, and usually present acute intestinal obstruction with strangulation of the small bowel. We report a 74-year-old male with initial manifestation of peritonitis. Internal hernia-induced intestinal obstruction with strangulation was highly suspected from the image study. After an urgent exploratory laparotomy, transomental hernia was diagnosed.

Abdominal hernia repair is one of the most common surgical procedures. Current data indicate that the best treatment results are achieved with use of synthetic material to reinforce weakened abdominal wall. Prosthetic materials utilized for hernia repair induce adhesions with underlying viscera. They should be therefore separated from them by a layer of peritoneum otherwise adhesions may cause to serious complications such as bowel-skin fistulas. The aim of our work was to determine if implantation of our collagen membrane into abdominal wall defect induce adhesions in rat model of ventral hernia. The collagen film was obtained by acetic acid extraction of rat tail tendons and than casting the soluble fraction onto polyethylene shits. Abdominal wall defect was created in 10 Wistar male rats. Collagen membranes were implanted into the defect using interrupted polypropylene stitches. After 3 months of observation all animals were sacrificed. No adhesions between path structure and bowel developed. In one often rats (10%) adhesion between fixating stitch and omentum was observed. Complete mesothelium lining and vascular ingrowth were microscopically observed within implanted structure. Promising result requires further confirmation in a larger series of animals.

Internal hernia may be either congenital or acquired. Its incidence has been reported to be 1-2%. Herniation may be persistent or intermittent. Internal hernia is a rare cause of small bowel obstruction with a reported incidence of 0.2-0.9%. The most common type is paraduodenal. Less common types include mesocolic hernia, which occurs following abdominal surgery. We report mesocolic hernias in two young patients, which presented as small bowel obstruction without any prior abdominal surgery.

Internal hernia may be either congenital or acquired. Its incidence has been reported to be 1-2%. Internal hernia is a rare cause of small bowel obstruction with a reported incidence of 0.2-0.9%. The herniation may lead to a variable degree of vascular compromise to the herniated bowel. We report a rare case of spontaneous transmesenteric hernia of ileum with associated gangrene of bowel caused by a congenital mesenteric defect in a 35-year-old adult male, and review the relevant literature.

The management of complex abdominal wall defects is challenging and often requires an individualized strategy with additional measures to minimize morbidity and recurrence. We retrospectively reviewed all patients who underwent reconstruction of complex abdominal wall defects at Emory Hospital by the senior author over a 7-year period. Abdominal hernia defects were categorized into primary, secondary, and tertiary hernias; infection; composite tumor defects; and dehiscence. Charts were queried for comorbidities, surgical technique, and outcome measures such as complications and recurrence. A total of 165 patients included in the series, with an average age of 52 years, and an average body mass index of 38 kg/m. Mesh was used in 81.8% of cases, 77% of those (mesh) being acellular dermal matrices (ADM). Component separation was performed in 75 patients (45.4%). The overall complication rate was 23.6% (39/165) including infection, delayed healing, skin necrosis, and fistulae, and was higher in patients with 2 or more comorbidities and those who required synthetic mesh reconstruction. The hernia recurrence or bulge was observed in 20.6% (34/165), and 29.4% of these patients required an additional, equally complex procedure. Hernia recurrence was significantly associated with a history of previous recurrent hernia, and hypertension (P < 0.04 and P = 0.001, respectively). Recurrence was higher in patients with 2 or more comorbidities (26% vs. 14%, P = 0.022). The recurrence rate was similar for synthetic and ADM reconstructions; however, the complication rates were higher when synthetic mesh was used. Attention to surgical technique, optimization of comorbidities, and the increased use of biologic meshes will minimize the need for operative intervention of complications following reconstruction of complex abdominal wall defects. Components separation and ADM have been very useful additions to the surgical management in these high-risk patients.
