Lateral pelvic lymph node dissection (LPND) is a technically demanding procedure. This study aimed to compare the short-term outcomes of laparoscopic and robotic LPNDs. This multi-institutional retrospective study included 108 consecutive patients who underwent laparoscopic or robotic total mesorectal excision with LPND for locally advanced rectal cancer. There were 74 patients in the laparoscopic and 34 in the robotic groups. The median operation time was longer in the robotic group than in the laparoscopic group (353 vs. 275 min, p < 0.001). No patients underwent conversion to open surgery in either group. Pathological LPN metastases were observed in 24 and 8 patients in the laparoscopic and robotic groups, respectively (p = 0.347). Although the number of harvested mesorectal lymph nodes was similar (15.5 vs. 15.0, p = 0.968), the number of harvested LPNs was higher in the robotic than in the laparoscopic group (7.0 vs. 5.0, p = 0.004). Postoperative complications and length of hospital stay were similar (robotic vs. laparoscopic, 35.3% and 7 days vs. 37.8% and 7 days, respectively). Both laparoscopic and robotic LPND are safe and feasible for locally advanced rectal cancers, but robotic LPND showed more harvested lateral lymph node than laparoscopic LPND.

The Korean Enhanced Recovery After Surgery (ERAS) Committee within the Korean Society of Surgical Metabolism and Nutrition was established to develop ERAS guidelines tailored to the Korean context. This guideline focuses on creating the most current evidence-based practice guidelines for ERAS purposes, based on systematic reviews. All key questions targeted randomized controlled trials exclusively, and if fewer than 2 were available, studies employing propensity score matching were also included. Recommendations for each key question were marked with strength of recommendation and level of evidence following internal and external review processes by the committee.

Globally, the incidence of gastric cancer is lower in women than in men. It is thought that menstrual and reproductive factors may be related to their lower incidence of gastric cancer. This cross-sectional study examined menstrual, reproductive, and other factors in 20,784 postmenopausal women from the 2007–2020 Korea National Health and Nutrition Examination Survey (KNHANES). A univariate logistic regression analysis was performed, and then a multivariate logistic regression analysis for significant factors in the univariate analysis was conducted. In the multivariate logistic regression analysis, the age at menarche (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.00−1.06, p = 0.035) and myocardial infarction (OR 2.43, 95% CI 1.05−5.62, p = 0.026) showed a significant association with increased incidence of gastric cancer. The age at menopause (OR 0.97, 95% CI 0.95−1.00, p = 0.03), the age at the first childbirth (OR 0.93, CI 0.89−0.97, p = 0.007), and the experience of alcohol consumption (OR 0.68, 95% CI 0.5–0.91, p = 0.003) showed a significant association with a decreased incidence of gastric cancer. Late menarche, early menopause, early aged first childbirth, and myocardial infarction are estimated to be risk factors for gastric cancer in postmenopausal Korean women.

Background/Objective: Surgical site infection (SSI) is a leading common condition after ileostomy reversal (IR). However, evidence is unclear that subcutaneous negative-suction drainage (SND) reduces the incidence of SSI. This study aimed to investigate whether SND effectively reduced the incidence of SSI. Methods: We retrospectively analyzed the records of 531 patients who underwent IR at Incheon St. Mary’s Hospital between June 2005 and December 2020. SND was classified into two groups based on its presence or absence. The estimated risk of SSI was calculated using the surgical risk calculator of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). After 1:1 propensity score matching (PSM) using the estimated risk of SSI, we analyzed the two group’s postoperative outcomes, including SSI rates. Results: After PSM, there was no difference in demographics between the two groups; however, the reversal interval was longer in the SND group than in the no SND group (193.3 ± 151.6 vs. 151.5 ± 141.0 days, p = 0.005). The incidence of SSI was lower in the SND group than in the no SND group (5.2% vs. 13.0%, p = 0.013). Conclusions: SND insertion can reduce the incidence of SSI during IR. Therefore, SND insertion should be considered as a basic technique for reducing SSI after IR.

Surgery for inguinal hernia has made significant progress over a period of more than a century. The advent of minimally invasive techniques prompted further innovations. Among these, single-incision surgery offers significant advantages in creating the preperitoneal space. Therefore, it is essential for surgeons to understand and be able to perform single-incision laparoscopic totally extraperitoneal (SIL-TEP) hernia repair. This article presents a detailed description of the surgical technique for SIL-TEP.
