Three cases of traumatic diaphragmatic hernia were repaired in this department from June 1967 to Nov.1968. The first case, a 14 year old girl, was diagnosed as diaphragmatic hernia during the operation of the diffuse peritonitis from jejunaI perforation 3 days after the traffic accident at local clinic and she was transfered to this hospital after the closure of the perforated jejunum. Herniated stomach, transverse colon, spleen and left lobe of the liver were repositioned and the diaphragmatic rupture at the posterolateral portion of the left diaphragm was repaired with two layer sutures by transthoracic approach. The second case. a 26 year old man. was diagnosed immediately after the traffic accident at local clinic and transfered to this hospital 24 hours later. Herniated and distended stomach, transverse colon and jejunum were repositioned and the large diaphragmatic rupture, about 9 cm in length, from the posterolateral portion to the base of the pericardium was directly repaired with two layer sutures. The third case, a 26 year old man, who had a history of stab wound at left lower lateral chest two years ago,was admitted with the sudden onset of abdominal pain and vomiting. The diaphragmatic hernia was confirmed with barium enema. The herniated stomach and transverse colon through the defect, about 3.5 cm in diameter, at anterolateral portion of the left diaphragm, were repositioned and the defect was repaired with two layer sutures. All of the cases recovered uneventfully.
Early recognition and surgical treatment of Hirschsprung's disease prevents serious mortality and morbidity from enterocolitis and obstruction. Usually this disease is characterized by a single aganglionic segment of the colon extending distally to the anal margin. In surgical treatment, the surgeon performs a frozen section biopsy to confirm whether there are ganglion cells. If there are intervening ganglionic sites in aganglionic bowel, there may be confusion in diagnosis and treatment. The authors experienced one case of total colonic aganglionosis with skip area. A transverse loop colostomy was performed on a 7 day-old male baby with colon perforation due to Hirschsprung's disease. But intestinal obstruction persisted and required two more operations to find the true nature of the disease. There were aganglionic segments from the anal margin to the terminal ileum 3.7cm proximal to the ileocecal valve. The entire transverse colon and appendix were normally ganglionated.
Although colonoscopy was originally a diagnostic imaging procedure, it has now expanded to include an increasing range of therapeutic interventions. These procedures require precise maneuvers of instruments, execution of force, efficient transmission of force from the operator to the point of application, and sufficient dexterity in the mobilization of endoscopic surgical instruments. The conventional endoscope is not designed to support technically demanding endoscopic procedures. In case of colonoscopy, the tortuous anatomy of the colon makes inserting, moving, and orientating the endoscope difficult. Exerting excessive pressure can cause looping of the endoscope, pain to the patient, and even perforation of the colon. To mitigate the technical constraints, numerous technically enhanced systems have been developed to enable better control of instruments and precise delivery of force in the execution of surgical tasks such as apposing, grasping, traction, counter-traction, and cutting of tissues. Among the recent developments are highly dexterous robotic master and slave systems, computer-assisted or robotically enhanced conventional endoscopes, and autonomously driven locomotion devices that can effortlessly traverse the colon. Developments in endoscopic instrumentations have overcome technical barriers and opened new horizons for further advancements in therapeutic interventions. This review describes examples of some of these systems in the context of their applications to advanced therapeutic colonoscopy.
Esophageal reconstruction was performed in 344 patients with irreversible stricture of the esophagus resulting from caustic burns at National Medical Center from 1959 to 1982.There were 113 males and 231 females, and ranging from 2.5 to 58 years of age, and mean age was 26.5 years, and 25 cases were less than 10 years old. Caustic materials were 286 [83.2%] alkali and 50[14.5%] acid. The most frequent stricture site was upper thoracic esophagus as 56.7%, and the next was cervical as 31.4%, and lower, 11.9%. The stomach was involved in 10.8% totally, and hypopharyngeal stricture was also noticed in 3.2%, and in 3 cases, hypopharyngeal reconstruction was needed due to extensive scar change. In 329 of total 344 cases, colon interposition was performed without resection of the strictured esophagus except 4 cases which were complicated T-E fistula or perforation, and most of them, about 10-15 cm of terminal ileum with right half of the colon was used as the graft. The left colon with anti-peristalsis was used as graft only in 30 cases. The most common postoperative complication was anastomotic leak as 16.7% of total cases, and it was 12.5% from neck, 3.3% from ileocolostoma and 0.9% from cologastrostoma. Next common complication was neck stenosis [8.8%], aspiration pneumonia [6.4%], and graft necrosis [3.9%] in order. Overall operative mortality was 5.5% [14/329], and main causes of death were graft necrosis, sepsis due to anastomotic leak, gastric bleeding, and intestinal obstruction. Besides of colon interposition, according to shape or level of the stricture, plastic repair or segmental resection and direct anastomosis was done in 9, and 1 of them were complicated stenosis at the anastomotic site. In lower stricture, esophagogastrostomy was done in 10 cases, and 1 case expired due to hepatitis, and anastomotic stenosis was occurred in 2 cases at 1.5 months and 2.4 years later. During follow-up of 298 cases colon interposition from 6 months to 22 years, 82.6% was excellent, and 2.9% was complained of mild discomfort, and 4 cases were dead laterly, but 3 of them were not related to reconstruction.
Ulcerative colitis, an inflammatory bowel disease, is primarily managed medically with a combination of 5-ASA and steroids. However, this chronic disease requires surgical management if symptoms persist or complications develop despite medical management. The clinical course, indications and outcome of surgical management of 21 patients under the age of 15 who were endoscopically diagnosed with ulcerative colitis at the Seoul National University Children's Hospital between January, 1988 and January, 2003 were reviewed. Mean follow up period was 3 years and 10 months. The mean age was 10.3 years old. All patients received medical management after diagnosis and 8 patients (38 %) eventually required surgical management. Of 13 patients who received medical management only, 7 patients (53 %) showed remission, 4 patients are still on medical management, and 2 patients expired due to congenital immune deficiency and hepatic failure as a result of sclerosing cholangitis. In 8 patients who received surgical management, the indications for operation were, 1 patient sigmoid colon perforation and 7 patients intractability despite medical management. The perforated case had a segmental colon resection and the other 7 patients underwent total colectomy with ileal pouch-anal anastomosis. One patient expired postoperatively due to pneumonia and sepsis. and 1 is still on medical management because of mild persistent hematochezia after surgery. Six other operated patients are doing well without medical therapy. Pediatric ulcerative colitis patients can be surgically managed if the patient is intractable to medical management or if complications such as perforation are present. Total colectomy & ileal pouch-anal anastomosis is thought to be the adequate surgical method.
Five cases of traumatic diaphragmatic hernia were repaired in the Department of Thoracic Surgery, Seoul National University Hospital, during the period from 1967 to 1974. The first case, a 14-year aid girl, was diagnosed as diaphragmatic hernia during laparotomy because of jejunal perforation 3 days after traffic accident. Herniated stomach, transverse colon, spleen and left lobe of the liver were repositioned and the diaphragmatic rupture on left posterolateral portion was repaired with two layers of nonabsorbable sutures by transthoracic approach. The second case, a 26-year old man,was diagnosed immediately after traffic accident at a local clinic and transferred to this hospital 24 hours later. Herniated stomach, transverse colon and jejunum were repositioned amd diaphragmatic rupture,about 9 cm in length,from the posterolat.edge to the base of pericardium was sutured in two layers. The third case, a 26-year old man who had stab wound on the left lower lateral chest two years ago,was admitted with sudden abdominal pain and vomiting. Upper gastrointestinal series with barium meal revealed diaphragmatic hernia. The herniated stomach and transverse colon through the defect,about 3.5cm in diameter, at anterolateral portion on the left side,were repositioned and repaired with two layers of nonabsorbable sutures. The forth case, a 26-year old man, sustained blunt trauma to the chest by a roller and was transferred to the emergency room complaining of dyspnea 40 minutes after the accident. The diaphragmatic rupture extended from left midaxillary line to contralateral anterior axillary line,about 20cm long, at anterior portion of diaphragm, which was repaired with two layers, of nonabsorbable sutures. The fifth case, a 4-year old girl, had two separate diaphragmatic ruptures on both sides, which were caused by traffic accident. Immediate upper gastrointestinal series after injury showed herniated stomach, colon and spleen into left Chest cavity. Another small rupture with anterior edge of right lobe of the liver in chest cavity was noted. These were repaired with non-absorbable sutures via thoracotomy.
A clinical study was performed on 75 cases of the esophageal cancer and benign esophageal diseases experienced at Department of thoracic & cardiovascular surgery, School of Medicine, Keimyung University during 3 year period from 1978 to 1982. Of 75 cases of the surgical esophageal diseases, there were 35 patients of the esophageal cancer. 17 patients of benign esophageal stenosis, 10 patients of esophageal perforation, 4 patients of diverticulum. 3 patients of achalasia, 2 patients of congenital T-E fistula, one of upper esophageal web, one of esophageal foreign body, one of leiomyoma and patient of hemangioma. First, esophageal carcinoma was more frequent in men than in women by a ratio of five to one, and the peak incidence occurred in the 5th to 6th decade. Dysphagia was the most common symptom in 88.6 percent of our cases. The tumor was located mostly in the middle & the lower one third [91.4%]. The histological diagnosis was made in 35 cases. The squamous cell carcinoma was the most common [82.9%] and the rest was the adenocarcinoma in the lower one third [17.1%]. Thirty-five cases were operated and resection was feasible in the twenty-five patients [71.4%] with 2 cases of hospital mortality [5.7%]. All but two of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from 7 to 70 years with average age of 32 years. Corrective operations were performed on 17 patients of esophageal stenosis of whom 12 patients had esophagocologastrostomy, 3 patients esophagogastrostomy and in non-corrosive esophageal stenosis one case and esophagoplasty and another case had release of external compression. There was one complication of stenosis of the esophageal perforation were traumatic in five cases, empyema in three cases, caustics in one case and postemetic in one case. 10 patients of the esophageal perforation underwent operation: primary closure in 5 cases, two staged colon interposition in 2, esophagogastrostomy in 1 and closed thoracotomy in 2 cases There were 2 complications of leakage of anastomosis sites in postoperative period. 4 patients of traction type of diverticulum underwent diverticulectomy & 3 patients of achalasia underwent modified Heller`s operation. 2 patients of congenital esophageal atresia had distal tracheoesophageal fistula & underwent one staged operation with the results of one death caused by pneumonia. Upper esophageal web had divulsion through the esophagoscope and foreign body in upper esophagus was removed through cervical esophagotomy. One case of leiomyoma in esophagus had esophagectomy and reconstruction with right colon. And one case of hemangioma in esophagus had esophagectomy & esophagogastrostomy.
Catheter related and perianal problems are common surgical complications encountered during the treatment of pediatric malignancies. However acute surgical abdominal emergencies are rare. The aim of this study is to review acute surgical abdominal complications that occur during the treatment of childhood malignancies. Out of a total of 1,222 patients who were newly diagnosed with malignant disease, between January 2003 and May 2008, there were 10 patients who required surgery because of acute abdominal emergencies. Their medical records were reviewed retrospectively. Hematologic malignancies were present in 7 patients (4 leukemia, 2 lymphoma, 1 Langerhans cell histiocytosis) and solid tumors in 3 patients (1 adrenocortical carcinoma, 1 desmoplastic small round cell tumor, 1 rhabdomyosarcoma). Seven patients had intestinal obstruction, two had gastrointestinal perforation and one, typhlitis. Intestinal obstructions were treated with resection of the involved segment with (N=2) or without (N=3) enterostomy. Two patients had enterostomy alone when resection could not be performed. Intestinal perforation was treated with primary repair. Typhlitis of the ascending colon was treated with ileostomy. Right hemicolectomy was necessary the next day because of the rapidly progressing sepsis. Three patients are now alive on chemotherapy and one patient was lost to followed-up. Among six patients who died, five died of their original disease progression and one of uncontrolled sepsis after intestinal perforation. Although rare, acute surgical abdominal complications can occur in childhood malignancies. Rapid and accurate diagnosis and appropriate operation are required for effective treatment of the complications.
Seventy neonates with congenital intestinal atresia and stenosis who were treated at pediatric surgical service. Hanyang University Hospital from September 1979 to December 1996 were analyzed retrospectively. The lesion occurred in 27 cases at the duodenum, in 26 cases at the jeiunum, in 13 cases at the ileum and in 2 cases at the pylorus and colon each. There were 10 multiple atresias and 7 apple-peel anomaly cases. The atresia predominated over the stenosis by the ratio of 4 : 1. Male to female ratio was 1.3 : 1. The average gestational age was 38 weeks, and the average birth weight was 2,754 grams. Though 22.9 % were borne prematurely and 34.3 % had low birth weight, 92.3 % of them had a weight appropriate for gestational age. Polyhydramnios(40 %) was more frequently observed in duodenal and jeiunal atresia while microcolon in ileal atresia(58.3 %). Weight loss and electrolyte imbalance occurred more frequently in the duodenal stenosis cases because of delayed diagnosis. Twenty(55.6 %) of 37 jeiunoileal atresia cases had evidence of intrauterine vascular accident : 4 intrauterine intussusception, 3 intrauterine volvulus and 3 strangulated intestine in gastroschisis, and 10 cases of intrauterine peritonitis. There were one or more associated anomalies in 45 patients (64.3 %). Preoperatively proximal loop volvulus developed in 3 cases and proximal loop perforation in 5 cases and one case each of distal loop perforation, duodenal perforation and midgut volvulus occurred in the jeiunoileal atresia. Overall mortality rate was 20 %.

Background: Although adjuvant chemotherapy is a standard treatment in stage III colon cancer, its benefit is not as clear for stage II patients. In this retrospective analysis, we aimed to evaluate the survival of patients with low-risk stage II colon cancer, the efficacy of adjuvant chemotherapy in high-risk stage II colon cancer patients, and prognostic factors in stage II disease. Materials and Methods: One hundred and seventeen patients who were diagnosed with stage II colon cancer between January 2006 and December 2011 were included in the study. Patients were stratified into two groups as being low-risk and high-risk according to risk factors for stage II disease. Adjuvant 5-fluorouracil-based chemotherapy were administered to the patients with risk factors. Results: Ninety-four patients were treated with adjuvant chemotherapy due to high risk factors and 23 were monitored without treatment. Median follow-up time was 43 months. In terms of disease free survival and overall survival, adjuvant chemotherapy did not provide a statistically significant difference. Univariate analysis demonstrated that bowel obstruction was the major risk factor for shortened disease-free survival, while bowel perforation and perineural invasion were both negative prognostic factors for overall survival. Conclusions: The recommendation of adjuvant chemotherapy for stage II colon cancer is not clear. In our study, it was found that adjuvant chemotherapy did not contribute to survival in high-risk stage II patients. Due to the fact that prognosis of stage II patients is good, many more patients will be needed for statistically significant differences in survival. Adjuvant chemotherapy containing 5 fluorouracil is being used to high-risk stage II patients although it is not a standard treatment approach.
