  • Tracheal neurilemoma, an extremely rare benign tracheal tumor that there has been only one case reported in 1996 throughout the nation, is a slowly progressing disease that obliterates the upper airway, delays diagnosis for its symptom similarity to asthma, and makes intubation for operation difficult. Bronchoscopic is therefore needed for diagnosis. There are two options for the treatment methods, a bronchoscopic resection or open surgical resection; however if intubation is difficult, then the bronchoscopic resection is used first to keep the airway open for the surgical resection. In this case, the severe tracheal stenosis impeding intubation made the surgical resection of the primary tracheal neurilemoma with extratracheal mass impossible; therefore, bronchoscopic laser resection was applied first to optain the airway passage for endotracheal intubation, followed by a successful open surgical resection.

  • Purpose: Additional gastrectomy is needed after endoscopic resection for early gastric cancer when pathology confirms any possibility of lymph node metastasis or margin involvement. No studies depicted the optimal type of surgery to apply in these patients. We compared the short-term and long-term outcomes of laparoscopic gastrectomy with those of open gastrectomy after endoscopic resection to identify the optimal type of surgery. Materials and Methods: From 2003 to 2010, 110 consecutive patients who underwent gastrectomy with lymphadenectomy either by laparoscopic (n=74) or by open (n=36) for gastric cancer after endoscopic resection were retrospectively analyzed. Postoperative and oncological outcomes were compared according to types of surgical approach. Results: Clinicopathological characteristics were comparable between the two groups. Laparoscopic group showed significantly shorter time to gas passing and soft diet and hospital day than open group while operation time and rate of postoperative complications were comparable between the two groups. All specimens had negative margins regardless of types of approach. Mean number of retrieved lymph nodes did not differ significantly between the two groups. During the median follow-up of 47 months, there were no statistical differences in recurrence rate (1.4% for laparoscopic and 5.6% for open, P=0.25) and in overall (P=0.22) and disease-free survival (P=0.19) between the two groups. Type of approach was not an independent risk factor for recurrence and survival. Conclusions: Laparoscopic gastrectomy after endoscopic resection showed comparable oncologic outcomes to open approach while maintaining benefits of minimally invasive surgery. Thus, laparoscopic gastrectomy can be a treatment of choice for patients previously treated by endoscopic resection.

  • To clarify whether gastric cancer patients can benefit from laparoscopy-assisted surgery completed by junior surgeons under supervision of expert surgeons, data of 232 patients with gastric cancer underwent operation performed by inexperienced junior surgeons were reviewed. Of the 232 patients, 137 underwent laparoscopy-assisted resection and in 118 cases this approach was successful. All of these 118 patients were assigned to laparoscopic group in this study, 19 patients who were switched to open resection were excluded. All laparoscopic operations were performed under the supervision of expert laparoscopic surgeons. Some 95 patients receiving open resection were assigned to the open group. All open operations were completed independently by the same surgeons. Short-term outcomes including oncologic outcomes, operative time intra-operative blood loss, time to first flatus, time to first defecation, postoperative hospital stay and perioperative complication were compared between the two groups. The numbers of lymph nodes harvested in the laparoscopic and open groups were $21.1{\pm}9.6$ and $18.2{\pm}9.7$ (p=0.029). There was no significant difference in the length of margins. The mean operative time was $215.9{\pm}32.2$ min in laparoscopic group and $220.1{\pm}34.6min$ in the open group (p=0.866), and the mean blood loss in laparoscopic group was obviously less than that in open group ($200.9{\pm}197.0ml$ vs $291.1{\pm}191.4ml$; p=0.001). Time to first flatus in laparoscopic and open groups was $4.0{\pm}1.0$ days and $4.3{\pm}1.2$ days respectively and the difference was not significant (p=0.135). Similarly no statically significant difference was noted for time to first defecation ($4.7{\pm}1.6$ vs $4.8{\pm}1.6$, p=0.586). Eleven patients in the laparoscopic group and 19 in the open group suffered from peri-operative complications and the difference between the two groups was significant (9.3% vs 20.0%, p=0.026). The conversion rate for laparoscopic surgery was 13.9%. Patients with gastric cancer can benefit from laparoscopy-assisted operations completed by inexperienced junior surgeons under supervision of expert laparoscopic surgeons.

  • Purpose: This study analyzes the impact of laparoscopic liver resection on intra-abdominal adhesion. Methods: Patients who underwent salvage liver transplantation after liver resection for hepatocellular carcinoma from January 2012 to October 2017 at our institution were included. Information about the severity of intra-abdominal adhesions was collected from a prospectively maintained database. Intra-abdominal adhesions were graded after the agreement of 2 surgeons who participated in the salvage liver transplantation based on predetermined criteria. Adhesion severity and demographic, operative, and postoperative data were compared between the laparoscopic group and the open group. Multivariate logistic regression was performed to consider potential factors related to severe adhesion during salvage transplantation. Results: Sixty-two patients who underwent salvage liver transplantation after liver resection were included in this study. Among them, 52 patients underwent open surgery, and 10 patients underwent laparoscopy. Adhesion was significantly more severe in the open group than in the laparoscopy group (P = 0.029). A multivariate logistic regression model including potential factors related to severe adhesion showed that laparoscopy (odds ratio, 0.168; 95% confidence interval, 0.029-0.970; P = 0.048) was the only significant factor. Conclusion: Laparoscopic liver resection for hepatocellular carcinoma can minimize intra-abdominal adhesion during salvage liver transplantation.

  • Standard open procedures for resection of the first rib in thoracic outlet syndrome can prove to be quite difficult with extensive incisions. A minimal invasive procedure can also be painstaking, but provides an attractive alternative to the more radical open procedures. We report the details of the technique with direct video footage of the procedure performed in a 41-year-old man with thoracic outlet syndrome done entirely by thoracoscopic methods.

  • Purpose: This study evaluated the clinical outcome of arthroscopic debridement of anterior compartment and mini-open resection of posterior osteophyte for the treatment of primary osteoarthritis of the elbow. Materials and Methods: Between March 2003 and Feburary 2010, 19 cases who were performed arthroscopic debridement of anterior compartment and resection of posterior osteophyte through mini-open procedure for refractory osteoarthritis of the elbow were enrolled. Average follow-up period was 19 months. Mean age was 49 years old. Clinical results were evaluated by the scoring system of Andrew-Carson Rating Scale (ACRS) and Mayo Elbow Performance Score (MEPS). Results: In the range of motion, flexion contracture was improved from $28.7^{\circ}$ preoperatively to $17.9^{\circ}$ postoperatively, further flexion was improved from $105.1^{\circ}$ to $121.8^{\circ}$. In the scoring system of MEPS, score was improved from 51.1 points preoperatively to 87.9 points in last follow up, 3 cases had in excellent result, 13 good and 3 fair. According to the scoring system of ACRS, score was improved from 92.9 points to 168.2 points, 3 excellent, 14 good and 2 fair. Except one case, all cases returned to preoperative ordinary daily living activity and their own job. Conclusion: For the treatment of refractory osteoarthritis of the elbow, arthroscopic debridement of the anterior compartment and mini-open resection of posterior osteophyte would be helpful on pain relief and functional recovery of the elbow. But this procedure was required long term follow-up in aspect of recurrence of osteophytes and progress of arthritis of the elbow.

  • Purpose: To evaluate the technical feasibility and oncologic safety, we assessed the short-term and long-term outcomes of laparoscopic resection of the small bowel gastrointestinal stromal tumors smaller than 5 cm by comparing those of open surgery by subgroup analysis based on tumor size. Materials and Methods: From November 1993 to January 2011, 41 laparoscopic resections were performed among the 95 patients who underwent resection of small intestine ${\leq}10$ cm in diameter. The clinicopathologic features, perioperative outcomes, recurrences and survival of these patients were reviewed. Results: The postoperative morbidity rates were comparable between the 2 groups. Laparoscopic surgery group showed significantly shorter operative time (P=0.004) and duration of postoperative hospital stay (P<0.001) than open surgery group and it was more apparent in the smaller tumor size group. There were no difference in 5-year survival for the laparoscopic surgery versus open surgery groups (P=0.163), and in 5-year recurrence-free survival (P=0.262). The subgroup analysis by 5 cm in tumor size also shows no remarkable differences in 5-year survival and recurrence-free survival. Conclusions: Laparoscopic resection for small bowel gastrointestinal stromal tumors of size less than 10 cm has favorable short-term postoperative outcomes, while achieving comparable oncologic results compared with open surgery. Thus, laparoscopic approach can be recommended as a treatment modality for patients with small bowel gastrointestinal stromal tumors less than 10 cm in diameter.
