Postoperative internal hernia is a rare clinical complication which often occurs after digestive tract reconstruction. Roux-en-Y anastomosis is a common type of digestive tract reconstruction. Internal hernia after Roux-en-Y reconstruction, which occurs mainly in the mesenteric defect caused by incomplete closure of mesenteric gaps in the process of digestive tract reconstruction, is systematically called, in our research, as mesenteric internal hernia after Roux-en-Y reconstruction. Such internal hernia can be divided, according to the different structures of mesentric defect, into 3 types: the type of mesenteric defect at the jejunojejunostomy (J type), the type of Petersen's defect (P type), and the type of mesenteric defect in the transverse mesocolon (M type). Because of huge differences in the number of cases and follow-up time among existing research reports, the morbidity of internal hernia after LRYGB fluctuates wildly between 0.2% and 9.0%. Delayed diagnosis and treatment of mesenteric internal hernia after Roux- en-Y reconstruction may result in disastrous consequences such as intestinal necrosis. Clinical manifestations of internal hernia vary from person to person: some, in mild cases, may have no symptoms at all while others in severe cases may experience acute intestinal obstruction. Despite the difference, one common manifestation of internal hernia is abdominal pain. Surgical treatment should be recommended for those diagnosed as internal hernia. A safer and more feasible way to conduct the manual reduction of the incarcerated hernia is to start from the distal normal empty bowel and trace back to the hernia ring mouth, enabling a faster identification of hernia ring and its track. The prevention of mesenteric internal hernia after Roux-en-Y reconstruction is related to the initial surgical approach and the technique of mesenteric closure. Significant controversy remains on whether or not the mesenteric defect should be closed in laparoscopic Roux-en-Y anastomosis. This article is to review the reports and researches on internal hernia resulting from the mesenteric defect after Roux-en-Y digestive tract reconstruction in recent years, so as to promote understanding and attention on this disease. And more active preventive measures are strongly suggested to be taken in operations where digestive tract reconstruction is involved.

We hereby report a case of diffuse pelvic peritoneal involvement by immunoglobulin G4-related disease (IgG4-RD). Numerous pelvic masses and nodules showing delayed enhancement on enhanced abdominal CT were found to congregate in the pelvic organs of a 57-year-old female presenting with intestinal subocclusion. The differentiation between peritoneal IgG4-RD and pelvic peritoneal carcinomatosis was only made by histopathology and immunohistochemistry performed after surgical resection. Autoimmune pancreatitis represents the historical prototype of IgG4-RD, but the spectrum of manifestations involving various organs has expanded during the last decade. In this report, we shortly review this clinical entity.

Self-expandable stents are widely available for the treatment of perforation of the gastrointestinal tract. Because of the risk of migration, there has been no report of the use of self-expandable stents for the treatment of perforation of the colon or rectum. This is a report of successful treatment of iatrogenic colonic perforation during balloon dilatation of anastomotic stricture with a fully covered stent. Fully covered, self-expandable metallic stents can be considered useful tools for management of this condition.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by multiple gastrointestinal hamartomatous polyps and mucocutaneous pigmentation. Peutz-Jeghers syndrome has an incidence of approximately 1 in 25,000 to 300,000 births. Crohn's disease is a chronic inflammatory bowel disease that typically manifests as regional enteritis with its incidence ranging from 3.1 to 14.6 cases per 100,000 person-years in North America. Herein, we report a case of a 30-year-old male patient who had both Peutz-Jeghers syndrome and Crohn's disease. We believe that this is the first case in Korea and the second report in the English literatures on Peutz-Jeghers syndrome coincidentally accompanied by Crohn's disease.

We report herein a case of intestinal amyloidosis with grave prognosis that caused intractable diarrhea and intestinal pseudo-obstruction, alternately in spite of intensive conservative treatment. A 44-year-old woman was admitted for fever, diarrhea, and crampy abdominal pain which had been continuned during 6 months. Abdomen CT scan showed edematous wall thickening of the small bowel and right colon, and colonoscopic biopsy revealed amyloid deposition in the mucosa. Monoclonal light chains in serum and/or urine were not detected and highly elevated serum amyloid A was shown. In spite of intensive treatment including oral prednisolone and colchicine, diarrhea and intestinal pseudo-obstruction developed alternately, general status rapidly got worsened and died after two months.

Anisakiasis usually occurs in the stomach and can easily be diagnosed by digestive tract endoscopy as opposed to enteric anisakiasis which is very rare and difficult to be diagnosed definitively. The most important and useful tool in diagnosing enteric anisakiasis is obtaining an accurate patient history of having eaten raw fish before the onset of symptoms. We report a case of small bowel obstruction caused by acute invasive enteric anisakiasis. A 60-year-old woman visited the emergency room suffering from sudden abdominal pain. She had eaten raw fish 1 day before the onset of symptom. Radiologic studies showed small bowel obstruction. However, no definitive cause could be found. An emergency laparotomy revealed edematous and dilated proximal jejunum and a focal stenosis of the distal jejunum. Segmental resection of the jejunum was performed, and histopathological examination revealed enteric anisakiasis. The patient was discharged on the 7th day after surgery following an uneventful course of recovery.

Paraduodenal hernias are a rare congenital malformation, but they are the most common internal hernias. They develop secondary to a failure in midgut rotation, which may lead to small bowel obstruction or other clinical manifestations. The authors recently experienced a case of a left paraduodenal hernia presenting with unusual symptoms of left flank pain and vomiting.
