Korean essentials of robotic surgery (KEROS) program for novice robotic surgeons: evaluating the educational impact and participant satisfaction of simulation training for developing robotic surgical skills.

Introduction:  As robotic surgery expands, standardized training is crucial for novice robotic surgeons. The Korean Essentials of Robotic Surgery (KEROS) program, developed by the Korean Society of Endo-laparoscopic and Robotic Surgery, offers such training. This study evaluates KEROS's educational effectiveness and participant satisfaction.

Intracorporeal anastomosis in minimally invasive right hemicolectomy: a nationwide survey of the Korean Society of Coloproctology.

Purpose: We investigated the current practices and perceptions of colorectal surgeons in South Korea regarding intracorporeal ileocolic anastomosis (IIA) in minimally invasive right hemicolectomy (RHC).

Methods: Members of the Korean Society of Coloproctology (KSCP) participated in an online survey encompassing demographic information, surgical experiences, methods for IIA, and advantages, barriers, and perceptions of IIA. We performed a statistical analysis of survey results.

Skeletal muscle gauge as a prognostic factor in patients with colorectal cancer.

Background: Although skeletal muscle index (SMI) and radiodensity (SMD) are well-known prognostic factors, the clinical impact of the integrated measure, known as skeletal muscle gauge (SMG), has been limited in patients with colorectal cancer (CRC).

Patients And Methods: A total of 727 and 268 patients with CRC at two tertiary centers were included and allocated into the training and test sets, respectively. Preoperative slice computed tomography images of the third lumbar area were evaluated for SMI and SMD.

Maternal Bochdalek Hernia during Pregnancy: A Systematic Review of Case Reports.

Background: Since the first report of a diaphragmatic hernia from Ambroise Paré's necropsy in 1610, the Bochdalek hernia (BH) of the congenital diaphragmatic hernia (CDH) has been the most common types with high morbidity and mortality in the neonatal period. Due to the nature of the disease, CDH associated with pregnancy is too infrequent to warrant reporting in the literature. Mortality of obstruction or strangulation is mostly due to failure to diagnose symptoms early.

Predictors of reoperation for perianal fistula in Crohn's disease.

Objective: Treating perianal fistula in cases of Crohn's disease (CD) remains challenging and the postoperative recurrence rate of perianal fistula is 22%-28%. This study aimed to identify the predictive risk factors for reoperation in Korean CD patients with perianal fistula.

Methods: Medical records of the patients with clinically and pathologically confirmed CD who underwent surgical treatment for perianal fistulas at four referral centers in Korea between March 2010 and February 2020 were retrospectively reviewed.

Severe abdominopelvic actinomycosis with colon perforation and hepatic involvement mimicking advanced sigmoid colon cancer with hepatic metastasis: a case study.

Background: Actinomycosis is a rare chronic invasive disease caused by Actinomyces spp. Although abdominopelvic actinomycosis, which involves the colon and the pelvic organs extensively, has been frequently reported, abdominopelvic actinomycosis presenting with colon perforation and hepatic involvement concurrently has yet to be reported.

Case Presentation: A 55-year-old woman presented at the emergency room with squeezing epigastric pain.

Evaluating the Feasibility of Single Incision Laparoscopic Appendectomy Performed by a Resident Based on Propensity Score Matching.

Purpose: Conventional laparoscopic appendectomy (CLA) has been considered the standard for the treatment of acute appendicitis. Recently, single incision laparoscopic appendectomy (SILA) has become an alternative option. There are few reports on the results of SILA performed by residents during the training period.

Poor prognostic factors in patients who underwent surgery for acute non-occlusive ischemic colitis.

Introduction: Ischemic colitis (IC) is a disease with high postoperative morbidity and mortality. Knowledge of the risk factors for postoperative mortality could be helpful in clinical decision making and in optimizing postoperative treatment.

Methods: From a prospective database, we conducted a retrospective medical record review of 50 patients who underwent surgery for IC between 2003 and 2011 at our institution.

The effectiveness of endoscopic submucosal resection with a ligation device for small rectal carcinoid tumors: focused on previously biopsied tumors.

Purpose: To evaluate the effectiveness of endoscopic submucosal resection with a ligation device (ESMR-L) on histologic complete resection for the treatment of small rectal carcinoid tumors in comparison with the treatment with endoscopic mucosal resection (EMR) alone.

Methods: Thirty-five patients with small rectal carcinoid tumors were enrolled prospectively for ESMR-L, and we retrospectively reviewed 74 carcinoid tumor patients who underwent EMR. The comparison between ESMR-L and EMR groups was analyzed including endoscopic and histologic complete resection and complications after resection.

Tristetraprolin down-regulates IL-23 expression in colon cancer cells.

Interleukin 23 (IL-23) is an inflammatory cytokine that plays an important role in tumor promotion. Expression of IL-23 is increased in cancer cells and correlates with tumor progression. However, the mechanisms regulating IL-23 expression in cancer cells are still unclear.

Risk factors for complications after bowel surgery in Korean patients with Crohn's disease.

Purpose: To assess the incidence and factors predictive of early postoperative complications in Korean patients who undergo surgery for Crohn's disease (CD).

Methods: We retrospectively assessed 350 patients (246 males, 104 females; mean age, 30 ± 9 years) who underwent surgery for primary or recurrent CD at Asan Medical Center between January 1991 and May 2010. The incidence and predictive factors of early postoperative complications were analyzed by both univariate and multivariate analyses.

Surgical outcomes after total colectomy with ileorectal anastomosis in patients with medically intractable slow transit constipation.

Purpose: The aim of this study was to evaluate outcomes of a total colectomy with ileorectal anastomosis in patients with slow transit constipation.

Methods: A retrospective review of 37 consecutive patients with slow transit constipation who underwent a total colectomy between 1994 and 2008 was undertaken. Preoperative and postoperative Wexner's constipation scores were collected and used to evaluate the outcomes after surgical treatment.

Clinical significance of pre- to post-chemoradiotherapy s-CEA reduction ratio in rectal cancer patients treated with preoperative chemoradiotherapy and curative resection.

Purpose: To evaluate the clinical significance of a reduction in serum carcinoembryonic antigen (s-CEA) concentration ratio from before to after preoperative chemoradiotherapy (CRT) in terms of recurrence and prognostic factors in rectal cancer patients.

Methods: We retrospectively evaluated 333 rectal cancer patients who received preoperative CRT followed by surgery with curative intent between January 2000 and December 2006. Patients were divided into three groups: those with pre-CRT s-CEA≤6 ng/mL (group 1), those with pre-CRT s-CEA>6 mg/mL and post-CRT s-CEA≥70% lower than pre-CRT s-CEA (group 2), and those with pre-CRT s-CEA>6 mg/mL and post-CRT s-CEA<70% lower or higher than pre-CRT s-CEA (group 3).

Symptomatic venous thromboembolism in Asian colorectal cancer surgery patients.

Background: The occurrence of venous thromboembolism (VTE), manifesting as deep vein thrombosis (DVT) or pulmonary embolism (PE), after colorectal cancer surgery in Asian patients remains poorly characterized. The present study was designed to investigate the incidence of symptomatic VTE in Korean colorectal cancer patients following surgery, and to identify the associated risk factors.

Methods: We retrospectively analyzed data from patients who developed symptomatic VTE after colorectal cancer surgery between 2006 and 2008.
