Purpose: The standard treatment of esophageal cancer is the Ivor-Lewis operation, which consists of an abdominal phase involving gastric tube formation, and a chest phase involving esophagectomy and anastomosis. We aimed to report our experience of performing thoracic esophagectomy with the laparoscopic gastric pull up (LGPU) technique and its surgical outcomes. Methods: Clinicopathologic data and short-term surgical outcomes of 14 patients who underwent LGPU for thoracic esophageal cancer from August 2008 to May 2016 were retrospectively reviewed. Results: Mean age of the patients was 62.3 years and mean body mass index was $21.7kg/m^2$. Eleven patients had medical comorbidities. Patients' mean American Society of Anesthesiologists score was 2. Mean operation time was 428.5 minutes, with the mean abdominal operation time being 138.9 minutes. There was no open conversion case. Three patients had pneumonia, three patients had surgical site infection, and one patient had subcutaneous emphysema within 30 days after surgery. One patient had minor anastomosis site leakage. There was one 30-day mortality case. One patient with postoperative aspiration pneumonia developed acute respiratory distress disease, and died due to sepsis. Mean postoperative intensive care unit stay was 3.5 days, and mean postoperative hospital stay was 20.6 days. Nasogastric tubes were removed on average at 3.4 days, and mean oral intake time was 3.4 days. Conclusion: If the gastrointestinal surgeon has extensive experience in laparoscopic procedures, LGPU will be a safe and feasible technique for thoracic esophagectomy in patients with intrathoracic esophageal cancer.

Rapid adoption of a robotic approach as a minimally invasive surgery tool has enabled surgeons to perform more complex hepatobiliary surgeries than conventional laparoscopic surgery. Although various types of liver resections have been performed robotically, parenchymal transection is challenging as commonly used instruments (Cavitron Ultrasonic Surgical Aspirator [CUSA] and Harmonic) lack articulation. Further, CUSA also requires a patient-side assistant surgeon with hepatobiliary laparoscopic skills. We present a case report of total robotic right hepatectomy for multifocal hepatocellular carcinoma in a 70-year-old male using 'Vessel Sealer' for parenchymal transection. Total operative time was 520 minutes with a blood loss of ~400 mL. There was no technical difficulty or instrument failure encountered during surgery. The patient was discharged on postoperative day five without any significant complications such as bile leak. Thus, Vessel Sealer, a fully articulating instrument intended to seal vessels and tissues up to 7 mm, can be a promising tool for parenchymal transection in a robotic surgery.

A rectocele with a weakened rectovaginal septum can be repaired with various surgical techniques. We performed laparoscopic posterior vaginal wall repair and rectovaginal septal reinforcement without mesh using a modified transperineal approach. A 63-year-old woman with outlet dysfunction constipation complained of lower pelvic pressure and sense of heaviness for 30 years. Initial defecography showed an anterior rectocele with a 45-mm anterior bulge and perineal descent. Laparoscopic procedures included peritoneal and rectovaginal septal dissection directed toward the perineal body, rectovaginal septal suturing, and peritoneal closure. The patient started a soft diet the following day and was discharged on the 5th postoperative day without any complications. The patient had no dyschezia or dyspareunia, and no problem with bowel function; 3-month follow-up defecography showed a decrease in bulging to 18 mm. Laparoscopic posterior vaginal wall and rectovaginal septal repair is safe and feasible for treatment of a rectocele, and enables early recovery.

Diverticula of the choledochus, better known as Todani type II cysts, are very rare and represent a predominantly pediatric pathology. Their identification by radiological methods, even if occasional, requires clinical doctors to request a surgical consultation, even for asymptomatic subjects, to proceed with their removal, given the risk of associated neoplasms. The laparoscopic approach for surgical treatment of these cysts has been recently introduced with excellent results. Due to the poor clinical records, currently there are neither shared protocols about their management nor long-term follow-up of operated patients. We report a case of an adult female suffering for years from biliary colic due to the presence of a duodenal diverticulum associated with microlithiasis' cholecystitis, who was laparoscopically treated, with excellent results in terms of symptomatic regression, reduced hospitalization, and no surgery-related complications.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.

Purpose: We evaluated the learning curve and short-term surgical outcomes of robot-assisted distal gastrectomy (RADG) performed by a single surgeon experienced in open, but not laparoscopic, gastrectomy. We aimed to verify the feasibility of performing RADG without extensive laparoscopic experience. Materials and Methods: Between July 2012 and December 2016, 60 RADG procedures were performed by a single surgeon using the da $Vinci^{(R)}$ Surgical System (Intuitive Surgical). Patient characteristics, the length of the learning curve, surgical parameters, and short-term postoperative outcomes were analyzed and compared before and after the learning curve had been overcome. Results: The duration of surgery rapidly decreased from the first to the fourth case; after 25 procedures, the duration of surgery was stabilized, suggesting that the learning curve had been overcome. Cases were divided into 2 groups: 25 cases before the learning curve had been overcome (early cases) and 35 later cases. The mean duration of surgery was 420.8 minutes for the initial cases and 281.7 minutes for the later cases (P<0.001). The console time was significantly shorter during the later cases (168.6 minutes) than during the early cases (247.1 minutes) (P<0.001). Although the volume of blood loss during surgery declined over time, there was no significant difference between the early and later cases. No other postoperative outcomes differed between the 2 groups. Pathology reports revealed the presence of mucosal invasion in 58 patients and submucosal invasion in 2 patients. Conclusions: RADG can be performed safely with acceptable surgical outcomes by experts in open gastrectomy.

Laparoscopic surgery has become popular in the past few decades, owing to less postoperative pain, fast recovery, and better cosmetic outcomes. The laparoscopic approach has been employed in pediatric surgery for the same reasons. After the first attempts of single incision laparoscopic appendectomy in pediatrics in 1998, single incision laparoscopic surgery (SILS) has recently been proven to be safe and feasible for the pediatric population. However, limitations have been reported for SILS, such as the wide learning curve, compared to standard laparoscopic surgery, and the restricted number of hospitals with surgical training programs including SILS. In this study, we intend to present our initial experiences with SILS in children, and to describe the technique, instruments used, and outcomes. This is a retrospective study of 71 pediatric patients who underwent SILS, at a tertiary medical center, between September, 2012 and August, 2013. Electronic medical records were reviewed for demographics, type of procedure, operation time, use of additional ports, conversion to open surgery, complications and hospital stay. Additional ports were inserted in 4 cases, for the purpose of traction. Postoperative complications were noted in 13 cases, which were mostly related to wound inflammation or formation of granulation tissue. According to our analyses, patients with complications had significantly longer use and more frequent use of pain killers. Notwithstanding the small sample size, many of the procedures performed in pediatric patients seem to be possible with SILS.

Hypertrophic pyloric stenosis (HPS) is the most common infantile surgical condition and the standard treatment is open pyloromyotomy. Recently, laparoscopic techniques have rapidly advanced, and the laparoscopic approach has become widely adopted by pediatric surgeons. The aim of this study was to compare the clinical outcomes between open and laparoscopic pyloromyotomy. We retrospectively evaluated outcomes of pyloromyotomy for HPS by the open (OP) and the laparoscopic (LP) method. The procedures were performed at the Samsung Medical Center between September 2001 and March 2009. We analyzed patient age, sex, birth weight, length of hospital stay, postoperative length of stay (LOS), operating time, time to feeding commencement, postoperative vomiting frequency, the time to full feeding without vomiting, and surgical complications. A total of 54 patients were included in the study. There were 26 OP and 28 LP patients. There was no statistically significant difference in age, sex, birth weight, operating time, postoperative emesis. In contrast, postoperative LOS in the LP group was statistically significantly shorter than that in the OP group (2.0 vs. 3.3 days, p=0.0003) and time to full feeding was significantly shorter following LP. (p=0.018) There were no wound complications. Laparoscopic pyloromyotomy significantly reduced postoperative LOS and time to full feeding compared to open pyloromyotomy.

Appendicitis is the most common surgical emergency in childhood. Open appendectomy has been the standard treatment. The minimally invasive techniques have been adopted in children after experiences in various surgical conditions in adults has accumulated. It is debatable whether laparoscopic appendectomy (LA) is superior to open appendectomy (OA) in children. The goal of this study is to review the results of laparoscopy and laparotomy in the nonperforated appendicitis. The records of 22 patients under 15 years of age who were operated upon for nonperforated appendicitis at Asan Medical Center were analyzed between December 2002 and April 2003. Age, type and length of intervention, frequency of analgesic use, complication, length of hospitalization, and cost for each treatment groups (N=11) were compared. Laparoscopy patients were older (13.0 vs. 10.1 years; p > 0.05), and operative time was longer (55.0 vs. 35.0 minutes; p < 0.05). There was no conversion (OA to LA). The median length of hospital stay was significantly shorter in laparoscopy (3.0 vs. 2.0 days; p < 0.05). The median cost for LA was more expensive (W833, 836 vs. W751,398; p < 0.05). Even though there were higher costs and longer operative times with laparoscopic procedures, the shorter hospital stay was an advantage.

Chronic abdominal pain remains a challenge to all known diagnostic and treatment methods with patients undergoing numerous diagnostic work-ups including surgery. However, the surgical treatment of patients with chronic intractable abdominal pain is controversial. There has been no discussion of the indications for adhesiolysis in cases of obstruction or strangulation of the bowel, and adhesiolysis by laparotomy has never gained acceptance as a treatment modality for chronic abdominal pain. One of the reasons for this lack of acceptance is the high complication rate during and after adhesiolysis. Laparoscopic surgery has been accepted as a technique for diagnostic and therapeutic procedures in general surgery. Laparoscopy allows surgeons to see and treat many abdominal changes that could not otherwise be diagnosed. Here we report two cases of successful symptomatic improvement through laparoscopic adhesiolysis for chronic abdominal pain without intestinal obstruction after total gastrectomy.
