Simultaneous laparoscopic surgery for colorectal cancer and coexisting abdominal disease is shown to be feasible. However, simultaneous laparoscopic colorectal resection and nephrectomy is rarely documented, and its feasibility is unknown. We report two cases of simultaneous colorectal resection for colorectal cancer and nephrectomy. In the first case, a 71-year-old female underwent laparoscopic right hemicolectomy for an ascending colon cancer and left nephrectomy for a left non-functioning kidney. The second patient was a 77-year-old male with descending colon cancer and left renal cell carcinoma who underwent laparoscopic left hemicolectomy and left nephrectomy. The body mass indexes were 21.73 and 26.78 kg/m², respectively, and operation time was 275 and 395 minutes. Blood loss was 300 and 250 cc, and the postoperative hospital stay was 8 and 10 days. In both cases, there was no postoperative morbidity or mortality. Simultaneous laparoscopic resection for colorectal cancer and nephrectomy is a feasible and safe procedure.

PURPOSE: We have explored the question of what benefits SUTI-TEP can provide over conventional three-port TEP (C-TEP) surgery for the treatment of inguinal hernia. METHODS: One hundred forty cases (70 SUTI-TEP and 70 C-TEP) were reviewed in this study. SUTI-TEP procedure was carried out with SILS™ port as we reported before. Patient demographics and perioperative outcomes of SUTI-TEP were analyzed and compared with those of C-TEP. RESULTS: There was no conversion to open surgery or C-TEP in SUTI-TEP group. Median VAS immediate postoperatively was slightly higher in SUTI-TEP group, but it was statistically significant. POD 7th day pain after surgery were similar in both groups. Regarding the length of operation time, SUTI-TEP group (71.2 min) was significantly longer than that of the C-TEP group (41 min) (p<0.001). There was no major morbidity or mortality postoperatively in either group. There was also no recurrence or chronic pain during follow up. Patient overall satisfaction including cosmetic outcome was excellent in SUTI-TEP group. CONCLUSION: Although the longer operation time tends to be required, SUTI-TEP can provide better cosmesis and patient satisfaction, and also safety. That may be good indicator of the success of after surgery. Also we should not presume that one large incision causes less pain than small multiple incision because it is just single one. If there is more pain in one single wound, we should find the solution through the innovation of technology or preventive measures.

PURPOSE: In order to enhance the goal of premedical education, we developed new clinical educational course of surgery for first-grade premedical students. METHODS: In 2015, from September 4th to December 18th, the educational performance records of firstgrade premedical students were evaluated, who attended the new, optional major class Introduction to surgery for future doctors. The non-compliance score was calculated as the sum of the total frequency of absences, number of late arrivals to class, and failure to submit the pre-lecture homework. This score was correlated with students' educational performance records. The premedical students' feed-back about this new class was summarized. RESULTS: Among 79 first-grade premedical students at Yonsei University College of Medicine, 43 premedical students (54.4%) chose to attend the new class. Premedical students' individual non-compliance scores were inversely and significantly correlated to written test performance (R²=0.237, p=0.001). In survey analysis, the mean score for premedical students' course satisfaction was 8.6. They strongly suggested this new educational course should be continued for first-grade premedical students with a mean rating of 9.1. Premedical students were very impressed and satisfied by laparoscopic surgical simulation and visiting the operating room, with ratings of 9.7 and 9.3, respectively. CONCLUSION: This class is the first movement to introduce the surgery to the premedical students in Yonsei University. In spite of their scanty medical knowledge, this clinical class can provide positive influence on educational motivation as premedical students. Further modification of this class is mandatory based on what we learned from this educational experience.

PURPOSE: Laparoscopic surgery has become the mainstream surgical operation due to its stability and feasibility. Even for liver surgery, the laparoscopic approach has become an integral procedure. According to the recent international consensus meeting on laparoscopic liver surgery, laparoscopic left lateral sectionectomy (LLS) might be a new standard of care for left lateral surgical lesions. This study was designed to compare open LLS to laparoscopic LLS. METHODS: In total, 82 patients who had undergone LLS at Chonnam National University Hwasun Hospital between 2008 and 2015 were enrolled in this study. Among them, 59 patients underwent open LLS and 23 underwent laparoscopic LLS. These two groups were compared according to general characteristics and operative outcomes. RESULTS: The data analysis results showed that laparoscopic liver resection is superior to open liver resection in terms of the amount of bleeding during the operation and the duration of hospital stay. There was no statistical difference between the two groups in terms of operation time (p value=0.747). The amount of bleeding during the operation was 145.5±149.4 ml on average for the laparoscopic group and 320±243.8 ml on average for the open group (p value=0.005). The mean duration of hospital stay was 10.7±5.8 days for the laparoscopic surgery group and 12.2±5.1 days for the open surgery group (p value=0.003). CONCLUSION: This study showed that laparoscopic LLS is safe and feasible, because it involves less blood loss and a shorter hospital stay. For left lateral lesions, laparoscopic LLS might be the first option to be considered.

PURPOSE: Laparoscopic cholecystectomy (LC) is now a standard operation for benign gallbladder (GB) disease. However, previous upper abdominal surgery (UAS) has been regarded as a relative contraindication for LC. The purpose of this study was to examine the effects of history of upper abdominal surgery including gastrectomy on the operative and postoperative results of LC. METHODS: A total of 769 patients underwent LC between March 2008 and December 2015, and the surgical outcomes of 45 patients who had a history of UAS were retrospectively compared with those who did not. Twenty of 45 patients with a history of UAS received gastrectomy, and the remaining 25 received non-gastrectomy UAS. The degree of adhesion and clinical outcomes were further compared between these two groups. RESULTS: The patients with a history of UAS required placement of a greater number of trocars, longer operation time, longer duration of drainage insertion, and higher open conversion rate (4.4%) compared to patients with no history of UAS. However, there were no significant differences in postoperative hospital stay or complication rate between the two groups. In the UAS group, 93.3% of patients required adhesiolysis. There were no significant differences in clinical findings or perioperative outcomes between gastrectomy group and non-gastrectomy group. CONCLUSION: A history of UAS including gastrectomy increases the technical difficulty of LC as well as open conversion rate. However, LC can be a feasible and safe approach when performed with adequate methods.

PURPOSE: Continued efforts to reduce the invasiveness of conventional cholecystectomy techniques have resulted in the development of single-incision cholecystectomy. However, a single-port approach has significant limitations associated with proper triangulation and instrument crowding and collisions. Although the da Vinci Single-Site robotic system has been proposed to overcome these problems, objective evidence of the feasibility and ergonomics of single-incision robotic cholecystectomy (SIRC) is insufficient. Therefore, the present study aimed to evaluate the feasibility and efficacy of SIRC by using objective data obtained from consecutive patients who underwent surgery with the single-incision robotic platform performed by a single surgeon. METHODS: Forty patients who underwent SIRC between August 2014 and December 2015 were identified. Demographic, perioperative, and postoperative data were collected retrospectively. RESULTS: The mean docking time was 10.82±4.85 min (range, 4~30 min). The mean console time was 49.63±10.82 min (range, 24~90 min). None of the patients required an additional laparoscopic arm, an additional robotic arm, or conversion to conventional laparoscopic cholecystectomy. CONCLUSION: SIRC can provide a safe operative procedure, good operative results, and high patient satisfaction, and cause less surgeon fatigue. Therefore, our study results indicate that SIRC is feasible and favorable for both patients and physicians.

In spite of lack of randomized control study, laparoscopic distal pancreatectomy (DP) is regarded as appropriate treatment in managing benign and low grade malignant tumor in distal part of the pancreas. With the advance of laparoscopic skills, innovative instruments, and perioperative management, clinical effort to reduce the access injury for laparoscopic DP has been attempted to enhance the cosmetic effect and the benefit of minimally invasive surgery. Due to inborn technical limitation of laparoscopic surgical system, it is not easy to perform laparoscopic reduced port-or single port-distal pancreatectomy (LRP/LSP-DP) in daily routine clinical practice, however, surgical technique for safe and effective LRP/LSP-DP has been developed. Till now, only a few experts reported the technical feasibility and safety of LRP/LSP-DP in selected patients. According to literature review, the number of the patients who underwent LRP/LSP-DP seems to gradually increase. In this moment, surgical experiences may be too limited to reach the conclusion, but, with the help of robotic surgical system, LRP/LSP-DP has potential room for further investigation. Therefore, minimally invasive surgeons need to pay attention to this innovative movement. In this review, currently available surgical techniques for LRP/LSP-DP has been summarized with some future perspectives on this technique.

PURPOSE: Minimally invasive central pancreatectomy has rarely performed because of its technical difficulty. Robot system enhances surgical dexterity to perform such complex procedures. METHODS: A 29-year-old woman was admitted with acute cholecystitis and an 1.4 cm enhancing mass was incidentally found at the pancreatic proximal body on computed tomography. Preoperative image studies suggested a neuroendocrine tumor or solid pseudopapillary neoplasm. The patient underwent robotic cholecystectomy and central pancreatectomy with pancreaticojejunostomy. RESULTS: The total operation time was 280 minutes and the estimated amount of intraoperative bleeding was 100 ml. The postoperative recovery was uneventful and she was discharged on the 7(th) postoperative day. Pathologic examination reported a solid pseudopapillary neoplasm. CONCLUSION: The technical difficulties associated with the procedure can be overcome with the help of the wrist-like movement of the robotic instruments, especially for the preservation of splenic vessels and for creating precise anastomoses in narrow spaces.
