Purpose: The purpose of this study was to examine the effects of a gum-chewing on the recovery of bowel motility and days of hospitalization after surgery for colorectal cancer. Methods: This study used a non-equivalent control group and non-synchronized design. Thirty-four patients undergoing abdominal surgery for colorectal cancer were assigned to either gum-chewing group (n=17) or control group (n=17). The patients in the gum-chewing group chewed gum for 10 min three times daily from the first postoperative morning until the day they began oral intake. Outcome variables were time of first flatus, time of first bowel movement, and length of hospital stay. Results: Gum-chewing was effective in enhancing the first passage of flatus, but was not effective in enhancing time of bowel movement and length of hospital stay. Conclusion: Gum-chewing can be utilized as a useful nursing intervention to shorten the time of the first flatus of postoperative colectomy.

Peutz-Jeghers syndrome is an autosomal dominant inherited syndrome characterized by mucocutaneous pigmentation and gastrointestinal hamartomatous polyps. The most important complications that increase morbidity are intussusception, bleeding and obstruction. Most patients with Peutz-Jeghers syndrome may undergo multiple laparotomies for complications such as intussusception or bleeding every 2 to 3 years during adolescence and early adulthood. To decrease the relaparotomy rate, intraoperative endoscopy may be useful in the treatment of complications that are related to Peutz-Jeghers syndrome. Use of intraoperative endoscopy can lead to a healthier life and to a longer life expectancy for the patient. We describe a case of Peutz-Jeghers syndrome, who underwent polypectomy by total gut endoscopy in an 11-year-old girl presented with intestinal obstruction and anemia. During the course of the operation, the endoscope was inserted per the enterostomy and colostomy sites, and 16 polyps in the small and large intestine were removed endoscopically using a snare.

Purpose: Malignant bowel obstruction caused by recurrent gastric cancer must be treated appropriately to improve the effects of treatment and to prolong survival. We reviewed the surgical treatments for malignant bowel obstruction caused by recurrent gastric cancer. Materials and Methods: The subjects were patients with malignant bowel obstruction caused by recurrent gastric cancer and these patients were treated by surgical procedures at our hospital from 1998 to 2008. The patients were treated by resection, ostomy or bypass. The success of treatment was decided when the patients were able to tolerate more than a liquid diet. Results: 42 patients were treated 46 times by surgical procedures. Resection was done12 times, ostomy was done 24 times and bypass was done 10 times. The hospital stay and the period to liquid diet after the operation were shorter in the ostomy group. The post operative morbidity rate was 21.7% and the post operative death rate was 8.7%. There was no significant difference in survival according to the type of surgery. Conclusion: Ostomy is good choice for selected patients because it has a shorter hospital stay and period to liquid diet. There was no significant difference in survival according to the type of surgery because curative resection is difficult to perform in patients with malignant bowel obstruction.

Purpose: Recently, the use of laparoscopic assisted gastrectomy for early gastric cancer has been on the increase and the procedure has been quickly adopted by clincians. However, there are few reports regarding the safety and risk of this type of surgery. The aim of this study is to evaluate the morbidity and to verify the safety of laparoscopic assisted gastrectomy for early gastric cancer. Materials and Methods: A total of 376 patients that had undergone laparoscopic assisted gastrectomy for early gastric cancer between April 2004 and December 2006 were reviewed retrospectively. The clinicopathological characteristics, operative complications, and factors related to complications were evaluated. Results: The overall operative morbidity and mortality rates were 10.6% and 0%, intraoperative morbidity was 1.1% (4 of 376 patients) and post operative morbidity was 9.6% (36 of 376 patients). Most complications required no surgery except for an intestinal obstruction in two cases. Multivariate analysis of risk factors related to operative morbidity determined that age was an independent factor associated with morbidity (P=0.021). Conclusion: The complication rate of laparoscopic assisted gastrectomy is low and most complications can be managed by conservative methods rather than with surgery. There were no specific predicting factors for complications except old age. Laparoscopy is a technically feasible and acceptable surgical modality for early gastric cancer.

Purpose: The aim of this study was to compare the short-term operative outcomes of laparoscopy-assisted total gastrectomy (LATG) with those of open total gastrectomy (OTG) for patients suffering with advanced upper gastric cancer. Materials and Methods: Of the 47 patients who underwent LATG with $D1+{\beta}$ or D2 lymphadenectomy from July 2004 to March 2008, 29 patients with pathologically proven advanced gastric cancer were compared with 35 patients who underwent conventional OTG during the same time period. The comparison was based on the clinicopathological characteristics, the surgical outcome, the follow-up survival and tumor recurrence. Results: The patients' age, gender and body mass index were similar between the two groups. However, there were statistically differences in tumor size ($9.2{\pm}3.9$ vs $6.1{\pm}3.6cm$, P=0.002) and the proximal resected margin ($2.1{\pm}2.0$ vs $3.6{\pm}2.1cm$ P=0.004). There was no significant difference in most of the peri- and post-operative courses such as the time to first flatus, the time to starting a solid diet and the length of the hospital stay, except for a longer operating time (289.0 vs. 361.3 minutes, P<0.001) in the LATG group. The complication rate was higher in the LATG group (13.8%) than that in the OTG group (5.7%). The mean overall survival and disease free survival times were 32 and 31 months, and 24 and 28 months, respectively, with an average 18.8 months follow-up duration. The main recurrent sites were peritoneum and lymph node in both groups. Conclusion: The early results of the current study suggest that LATG for AGC is technically feasible and it does not show any inferiorities of the postoperative outcomes as compared to those of conventional open total gastrectomy.

With an increasing awareness of the limitations of both mechanical prostheses and bioprostheses, aortic valvuloplasty has gained attention as an alternative procedure for aortic valve disease. Material and Method: Eight consecutive patients underwent aortic valvuloplasty caused by leaflet prolapse between June 1799 to June 2000. Mean age of the patients was 18.4$\pm$12.6 year. Four paitents(50%) were male. Six patients had tricuspid valves and ventricular septal defect and two patients had bicuspid valves. The extent of aortic insufficiency was 3.5$\pm$0.5 by preoperative Doppler echocardiography. The technique involved triangular resection of the free edge of the prolapsed leaflet, annular plication at the commissure, and resection of a raphe when present in bicuspid valves. Result: There was no in-hospital mortality or morbidity. Mean follow-up was complete at 11.973.6months. There was no late mortality or morbidity. The amount of the severity of aortic insufficiency, as assessed by echocardiography preoperatively, postoperatively and at late follow-up was 3.5$\pm$0.5, 0.6$\pm$0.5 and 0.8$\pm$0.6, respectively(p value : 0.01). There was one patient with grade 2/4 aortic insufficiency and in the other patients, grade 1/2 or trivial aortic insufficiency were detected with late echocardiograms. Conclusion: Triangular resection in the patients with aortic leaflet prolapse offers a good early clinical result, but long-term follow-up is necessary.

Barrett's esophagus is precancerous lesion of esophageal adenocarcinoma, but this has been rarely reported in Korea. A 81-year-old man with esophageal adenocarcinoma was admitted to our hospital, and we performed a distal esophagectomy and end-to-end esophagogastrostomy. The microscopic examination of the resected tissue revealed the intestinal metaplasia with goblet cells around the esophageal adenocarcinoma, which indicates this was a Barrett's esophagus. We report here on this case along with a review of the relevant literature.

Mucoepidermoid carcinoma is an uncommon lesion that accounts for approximately 1% of primary malignant bronchial gland tumors and less than 0.2% of all lung neoplasm. This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is uncommon, therefore complete surgical resection is the treatment of choice. The prognosis of tumor correlates with on the histologic grade of tumor. We experienced mucoepidermoid carcinoma in a 15 year-old girl with symptoms of cough and blood tinged sputum. The patient underwent successful removal of tumor by bilobectomy via explorothoracotomy after chest CT and bronchoscopic biopsy.

Purpose :We conducted a prospective non-randomized clinical study to evaluate the efficacy and toxic of the preoperative concurrent chemoradiotherapy for locally advanced unresectable rectal cancer. Materials and Methods: Between January 1995 and June 1998, 37 conecutive patients with locally unresectable advanced rectal cancer were entered into the study. With 3- or 4- fields technique, a total of 45 Gy radiation was delivered on whole pelvis, followed by 5.4 Gy boost to the primary tumor in some cases. Chemotherapy was done at the first and fifth week of radiation with bolus i.v. 5-Fluorouracil (FU) 370$\~$450 mg/m$^{2}$, days 1$\~$5, plus Leucovorin 20 mg/m$^{2}$, days 1$\~$5. OF 37 patients, 6 patients did not receive all planned treatment course (refusal in 4, disease progression in 1, metastasis to lung in 1). Surgical resection was undergone 4$\~$6 weeks after preoperative concurrent chemoradiotherapy. Results :Complete resection rate with negative margins was 94$\%$ (29/31). Complete response was seen in 7 patients (23$\%$) clinically and 2 patients (6$\%$) pathologically. Down staging of tumor occured in 21 patients (68$\%$). Treatment related toxicity was minimal except grade III & IV leukopenia in 2 patients, respectively. Conclusion : Preoperative concurrent chemoradiotherapy in locally advanced rectal cancer was effective in inducing down staging and complete resection rate. Treatment related toxicity was minimal. Further follow up is on-going to determine long term survival following this treatment.
