BACKGROUND: Although inguinal hernia in patients with liver cirrhosis (LC) is not uncommon, literature comparing operative complications and long-term recurrence rate after inguinal hernia repair in LC patients and non-LC patients is limited. METHODS: A total of 780 eligible patients including 129 (16.5%) patients with LC underwent inguinal hernia repair with the standard McVay procedure by a single surgeon over a 10-year period. Patients were prospectively registered and clinical data were anal

AIM: The aim was to determine the efficacy of probiotics in restoring bowel function following ileostomy reversal in patients with rectal cancer. METHOD: This was a pilot, randomized, double-blind, placebo-controlled trial. The probiotic used in this study, Lactobacillus plantarum CJLP243, was derived from kimchi. Patients were randomly allocated to a probiotic or placebo group and medication was taken once daily from preoperative day 1 to day 21. Primary outcomes were the Memorial Sloan Ketteri

Compared with right-sided diverticular disease, the incidence of left-sided disease in Korea has increased since 2001 and is associated with worse surgical outcomes.

AIM: This study aimed to investigate the association between Twitter exposure and the number of citations for coloproctology articles. METHOD: Original articles from journals using Twitter between June 2015 and May 2016 were evaluated for the following characteristics: publishing journal; article subject; study design; nationality, speciality and affiliation of the author(s); and reference on Twitter. Citation data for these articles were retrieved from Google Scholar (https://scholar.google.com

This study shows that an injection of polycaprolactone beads containing autologous myoblasts may improve anal sphincter function in an animal model of fecal incontinence.

PURPOSE: To examine the ability of generative artificial intelligence (GAI) to answer patients' questions regarding colorectal cancer (CRC). METHODS: Ten clinically relevant questions about CRC were selected from top-rated hospitals' websites and patient surveys and presented to three GAI tools (Chatbot Generative Pre-Trained Transformer [GPT-4], Google Bard, and CLOVA X). Their responses were compared with answers from the CRC information book. Response evaluation was performed by two groups, e

Perianal diseases are the most common reasons for surgery in HIV-positive patients. This study aimed to evaluate the outcomes of these surgical procedures in Korean patients, focusing on wound healing and postoperative complications. Retrospective analysis was performed on 72 HIV-positive patients who underwent surgery by a single surgeon for benign anal disease between 1998 and 2011. Of these, 68.1% (49/72) of patients received surgery for condyloma acuminata, 19.4% (14/72) for anal fistulas, 6

AIM: Rigid surgical instruments limit movement whereas articulated instruments offer better control in small spaces and allow for intuitive and ergonomic movements. However, the effectiveness of the use of articulated instruments in improving colorectal laparoscopic outcomes remains unclear. The aim of this work was to determine whether colorectal laparoscopic surgical proficiency improved when multijoint instruments were used instead of conventional ones. METHOD: We enrolled 70 consecutive pati
