Intersphincteric resection (IRS) is a surgical technique used to preserve sphincter function, mainly cases of low rectal cancer located less than 5 cm from the anal verge [1, 2]. There have been reports of laparoscopic ISR [3, 4], but discussion of the specific techniques used in this laparoscopic surgical procedure have not been sufficient. For better outcomes of this sophisticated procedure, extreme care must taken to prevent perforation of the rectal wall and to preserve the external sphincter muscle. The most difficult steps for ISR are the circular dissection and separation of the internal sphincter muscle from the external sphincter and puborectalis using the perineal approach. The authors' techniques and the advantages of laparoscopic ISR are shown by a video presentation of three rectal tumor cases. Also, the perioperative outcomes for the patients who underwent laparoscopic ISR with this technique are described. ⋯ The mean duration of surgery was 386 min, and the mean blood loss was 108 ml. The mean postoperative hospital stay was 18 days. The diverting ileostomy was closed at a mean of 7.3 postoperative months. No remarkable perioperative complication was encountered (Table 2). Table 2 Perioperative outcomes (n=15) Duration of surgery: min (range) 386 (319-510) Blood loss: ml (range) 108 (0-180) Postoperative hospital stay: days (range) 18 (11-31) COMPLICATIONS: n (range) Anastomotic leakage 1 Stricture of the anastomosis 1 Pelvic abscess 1 Postoperative period until the stoma closure (months) 7.3 (3-16) CONCLUSION: Laparoscopic ISR enabled reduction of the difficulties associated with the perineal approach. An advantage of laparoscopic ISR is the ability clearly to visualize anatomic structures in the deep pelvic cavity.

Comparative Study
Comparison of laparoscopy-assisted and total laparoscopic Billroth-I gastrectomy for gastric cancer: a report of short-term outcomes.
The safety and efficacy of laparoscopic gastrectomy in the treatment of early gastric cancer have been demonstrated in many clinical studies. Most surgeons prefer laparoscopy-assisted gastrectomy with extracorporeal anastomosis rather than total laparoscopic procedures because of the technical difficulties of intracorporeal anastomosis. This study assessed the efficacy of total laparoscopic Billroth-I (B-I) gastrectomy. ⋯ TLDG can be performed safely after appropriate experience with LADG. Our results imply that TLDG may lead to faster recovery, better cosmesis, and improved quality of life in the short-term compared with LADG. Because of the limitations of a retrospective analysis on the study and a patient selection bias, a prospective randomized study should be conducted to reach definitive conclusions.

Comparative Study
A comparison of surgical outcomes between endoscopic and robotically assisted thyroidectomy: the authors' initial experience.
The gasless, transaxillary endoscopic thyroidectomy (GTET) offers a distinct advantage over the conventional open operation by leaving no visible neck scar, and in an attempt to improve its ergonomics and surgical outcomes, the robotically assisted thyroidectomy (RAT) was introduced. The RAT uses the same endoscopic route as the GTET but with the assistance of the da Vinci S robotic system. Excellent results for RAT have been reported, but it remains unclear whether RAT offers any potential benefits over GTET. ⋯ In our early experience, adding the da Vinci S robot to GTET increased the total procedure time and resulted in a higher pain score on day 0 but eliminated the need for any surgical assistant at the time of the operation.

Laparoscopic approach has become standard for many ventral hernia repairs. The benefits of minimal access include reduced wound complications, faster functional recovery, and improved cosmesis, among others. However, "bridging" of hernia defects during traditional laparoscopic ventral hernia repair (LVHR) often leads to seromas or bulging and, importantly, does not restore a functional abdominal wall. We have modified our approach to LVHR to routinely utilize transabdominal defect closure ("shoelacing" technique) prior to mesh placement. Herein, we aim to analyze outcomes of LVHR with shoelacing. ⋯ LVHR with defect closure confers a strong advantage in hernia repair, shifting the paradigm towards more physiologic abdominal wall reconstruction. In this series, we found our approach to be safe and comparable to historic controls. While providing reliable hernia repair, the addition of defect closure in our patients essentially eliminated postoperative seroma. We advocate routine use of the shoelace technique during laparoscopic ventral hernia repair.
