Uterine cervical cancer is the most common malignancy in korean women. In spite of recent development of early diagnostic and therapeutic modalities, about 40% of treated patient will develop relapse. So more aggressive local treatment such as more extensive surgery and higher radiation dose and administration of systemic chemotherapy will promote the curability but treatment related complications can not be avoidable. We used 22 cases of early cervical cancer, treated with surgery and post-operative radiotherapy, clinical data of these patients were analized to determine relationship between clinical parameters and final outcome. Three out of 22 cases revealed relapse and one patient showed rectovaginal fistula and another patient showed small bowel obstruction and the other patient showed rectal obstruction. Two out of three recurrence were stage IIa and the other one case was stage Ib adenocarcinoma with lymphovascular involvement. Nineteen out of 22 cases were followed without remarkable side effect or treatment related complication or sequelae. We concluded that our treatment policy was safe and effective to eradicate high risk postoperative cervical cancer with acceptable side effects or complication.

Peutz-Jeghers syndrome is a rare syndrome with characteristic features of multiple hamartomatous polyps and mucocutaneous pigmentation. This syndrome is an autosomal dominant disease, and has complications related with polyps of the gastrointestinal tract, such as small bowel obstruction, iron deficiency anemia associated with bleeding, and intussusceptions. Many studies have reported about higher cancer risk of patients with this syndrome than those with no syndrome in the gastrointestinal tract, including gastric, duodenal, jejunal and the extragastrointestinal organs, such as gallbladder, breast and reproductive system. There are guidelines for periodic test for early detection and treatment for higher risk organs. We report a case of Peutz-Jeghers syndrome patient in the emphasis of Oral and Maxillofacial surgeon's role with review of the literature.

Portal vein gas and pneumatosis cystoides intestinalis are uncommon conditions and have been associated with poor prognosis. They are most commonly caused by necrotizing enterocolitis but may have other causes, and they can be associated with necrotizing and ischemic colitis, intra-abdominal abscess, small bowel obstruction, diverticulitis, colon cancer, and acute pancreatitis. With the more frequent use of computed tomography (CT) scans, portal vein gas and pneumatosis cystoides intestinalis have been increasingly detected in recent years. Because of its high mortality rate, necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis may be treated with emergent exploratory laparotomy. We report a case of necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis in a 47-year-old man treated with intensive medical management and delayed operation due to unstable condition and surgical mortality. He had good clinical results without complications after the delayed operation.

Intestinal malrotation is a developmental anomaly resulting from embryologic failure of fixation and rotation of the gut and predisposed to midgut volvulus and small bowel obstruction. Acute midgut volvulus is most often encountered in the newborn period. But older children and adults may have a history of intermittent episodes of partial volvulus presenting with recurrent colicky abdominal pain accompanying bilious vomiting. We experienced a case of intestinal malrotation complicated by midgut volvulus presented with recurrent vomiting and abdominal pain in a 6-year-old boy.

Spontaneous intramural hematoma is a rare complication of oral anticoagulants, and its incidence is expected to increase because of the increasing number of elderly patients undergoing anticoagulant therapy. Clinical manifestations of spontaneous intramural hematoma vary from mild abdominal pain to intestinal obstruction or acute abdomen. Early diagnosis is important because most patients can be treated successfully without surgery. The role of endoscopy in the diagnosis of intramural hematoma is not well established because almost all cases are diagnosed non-invasively with computed tomography scans. However, confirmation of the intramural hematoma through direct visualization of the involved bowel mucosa is helpful, if the imaging diagnosis is uncertain. We report a case of anticoagulant-induced spontaneous intramural hematoma, which was diagnosed using endoscopy, with relevant literature review.

The role of adjuvant chemotherapy in patients with stage II colon cancer remains a controversial issue. Adjuvant chemotherapy aims to eliminate any micrometastatic disease that may have been missed, at the time of surgery. Although one prospective study showed a small but statistically significant benefit with respect to the overall survival for those who received adjuvant chemotherapy, multiple pooled data did not demonstrate any benefit of this therapy in patients with stage II colon cancer. Current national and international guidelines for the adjuvant treatment of stage II colon dose not advise routine implementation of adjuvant chemotherapy, but rather recommend selective use of this therapy for patients with high risk of recurrence. High risk features for recurrence include T4 disease, poorly differentiated histology, presence of lymphovascular invasion, presence of perineural invasion, inadequate retrieval of lymph nodes, bowel obstruction, localized perforation, or positive margins. More recently, prediction tools using gene expression cancer profiles are proposed to identify patients who are most likely to have recurrence and therefore may benefit from postoperative chemotherapy in stage II colon cancer. These novel methods together with conventional prognosticators, will allow us to implement more optimized personalizing adjuvant therapy in these patients.

Diverticulosis of the small intestine is a rare entity, compared with that of duodenum or colon, and is found in only 1% of autopsied patients. The main complications are diverticulitis with or without a perforation, obstruction and hemorrhage, which are associated with a high mortality. Intussusception is primarily a disease of childhood; with only 5 to 10% of cases occurring in adults. In contrast to childhood intussusception, 90% of adult intussusception cases are had an associated pathologic processes. An inflammatory fibroid polyp is an uncommonly localized non-neoplastic lesion of the gastrointestinal tract. It occurs most often in the stomach and secondly in the ileum. It rarely occurs in other organs such as the colon, jejunum, duodenum and esophagus. We report a case of jejunal diverticulitis with a perforation combined with intussusception caused by an inflammatory fibroid polyp. A 78-year-old female presented with abdominal pain, fever and chill. Contrast CT scan showed intussusception of the ileum. The patient was treated with a small bowel segmental resection. After surgery, the specimen showed jejunal diverticulitis with perforation.

Cervix cancer is the most common female cancer in Korea. In spite of their relatively local invasive tendency, still $44\%$ of patient will develop recurrent cancer. This result suggests that more aggressive local treatment may increase the cure rate but increased complication risk also cannot be avoidable. Various institutions proposed different treatment regimen, but recommended dose were about 4500 cGy for whole pelvis and 8000 cGy at point A, even though they agreed that those doses may not be satisfactory for control of bulky disease. 96 cases of invasive cervical cancer, treated with postoperative or primary radiation therapy were analyzed to determine the complication rate and prognostic factor in our treatment regimen Which is $5500\~1000 CGy$ higher than Other institution. Mean follow up duration was 21 months. Symptomatic patients including mild but persistent abdominal discomfort was $46\%$, but only 1 patient $(1\%)$ had operative treatment because of incomplete obstruction of small bowel. Most symptoms appeared within 12 months and most common complaints were frequent bowel movement. Barium enema and sigmoidoscopy were performed for persistent symptomatic patients. Only one patient had abnormal finding in barium enema which showed inefficiency of this method for detecting bowel complication. Patient's age, total tumor dose, total TDF, rectal dose were not significant risk factors for complication, but boost dose, previous history of operation had some relationship with complication risk. Even though dose of point A and rectum is $500\~1,000cGy$ higher than other institution, such a low rate of severe complications may suggest that fear of complications should not be overestimated than cure rate and the possibility of more aggressive treatment for better local control should not be underestimated.

Purpose: Alagille syndrome is a complex hereditary disorder that is associated with cardiac, hepatic, skeletal, ocular, and facial abnormalities. Mutations in the Notch signaling pathway, such as in JAG1 and NOTCH2, play a key role in embryonic development. A cardiac or hepatic presentation is a critical factor for determining the prognosis. Methods: We conducted a retrospective study of 41 patients with Alagille syndrome or a JAG1 mutation between 1983 and 2013. Results: The first presentations were jaundice, murmur, cyanosis, and small bowel obstruction at a median age of 1.0 months (range, 0-24 months). The JAG1 mutation was found in 27 of the 28 genetically-tested patients. Cardiovascular anomalies were identified in 36 patients, chronic cholestasis was identified in 34, and liver transplantation was performed in 9. There was no significant correlation between the severity of the liver and cardiac diseases. The most common cardiovascular anomaly was peripheral pulmonary stenosis (83.3%), with 13 patients having significant hemodynamic derangement and 12 undergoing surgical repair. A total bilirubin level of >15 mg/dL with a complex surgical procedure increased the surgical mortality (P=0.022). Eight patients died after a median period of 2.67 years (range, 0.33-15 years). The groups with fetal presentation and with combined severe liver and heart disease had the poorest survival (P<0.001). Conclusion: The group with combined severe liver and heart disease had the poorest survival, and a multidisciplinary approach is necessary to improve the outcome.

Neurocristopathy originates from aberrant development of the neural crest by genetic abnormality. Dysgenetic or neoplastic neurocristopathy mayor may not combine at one or more organs. Congenital central hypoventilation syndrome (Ondine's curse) is characterized by the respiratory depression during sleep, although showing normal ventilation while awake, because the baby does not responde to hypercapnea or hypoxia. One newborn girl, full-term, 3,020 g of birth weight with neurocristopathy is reported. It showed poor respiration at birth, and temporary Improvement with oxygen and respiratory stimulations. Abdomen was distended. Abdominal x-ray revealed small bowel obstruction and calcified opacity at the right lower quadrant. Because transitional zone was noticed at the distal jejunum during laparotomy, jejunostomy was performed. Several times trial of extubation have failed becaused of the repeated apneas. Brain sonography and echocardiogram were normal. The patient died of sepsis at 37 days of age. Para-aortic ganglioneuroblastoma was found at autopsy. In this case, congenital central hypoventilation syndrome, Hirschsprung's disease and congenital ganglioneuroblastoma are combined as a neurocristopathy.
