Although long-term survival after TAE was comparable to that after TME, TAE had a greater recurrence risk than TME. Thus, TAE should only be considered as an alternative surgical option for early rectal cancer in selected patients.

In colorectal cancer, whereas mucinous adenocarcinoma (MAC) has several poor clinical prognostic factors compared to adenocarcinoma (AC), the prognosis of MAC remains controversial. We evaluated the prognosis of MAC without distant metastasis and the effects of adjuvant chemotherapy using health insurance registry data managed by South Korea. Patients with colorectal cancer between January 2014 and December 2016 were included (AC, 22,050 [96.8%]; MAC, 729 [3.2%]). We observed no difference in ov

New techniques have been developed to treat severe anastomotic strictures after rectal surgery. This report describes a new approach using transanal minimally invasive surgery for the treatment of complete anastomotic occlusion. A 49-year-old man presented with a completely occluded anastomosis after low anterior resection with temporary ileostomy for rectal cancer. The lumen was completely obstructed with a blind wall. A transanal surgical approach was used to treat the obstruction. Water-solub

Intestinal endometriosis is difficult to diagnose preoperatively because it mimics various intestinal diseases. Thus, if women of reproductive age have ambiguous symptoms and signs with nonspecific radiologic and/or endoscopic findings, intestinal endometriosis should be included in the differential diagnosis.

PURPOSE: To delineate the learning curve (LC) for laparoscopic appendectomy (LA) performed by residents according to seniority in training. METHODS: Between October 2015 and November 2016, 150 patients underwent LA by three residents (in their first, second, and third year of training) under supervision. The patients were non-randomly assigned to each resident. The data were reviewed and analyzed retrospectively from prospectively collected database. The perioperative outcomes were compared betw

BACKGROUNDS: Radiation therapy with concurrent chemotherapy is an important treatment for rectal cancer, especially for advanced stage disease. Low serum haemoglobin levels are accepted as a negative indicator in the response to radiation therapy. This study aimed to evaluate the relationship between anaemia and the response to preoperative chemoradiotherapy for rectal cancer and its effect on oncologic outcomes. METHODS: We retrospectively reviewed medical records of primary rectal cancer patie

Abstract Background An underweight individual is defined as one whose Body Mass Index (BMI) is < 18.5 kg/m 2 . Currently, the prognosis in patients with colorectal cancer (CRC) who are also underweight is unclear. Methods Information on South Korean patients who underwent curative resection for CRC without distant metastasis was collected from health insurance registry data between January 2014 and December 2016. We compared the overall survival (OS) of underweight and non-underweight (BMI ≥

Objectives. The "Sick Lobe" hypothesis states that breast cancers evolve from entire lobes or portions of lobes of the breast where initiation events have occurred early in development. The implication is that some cancers are isolated events and others are truly multi-focal but limited to single lobar-ductal units. Methods. This is a single surgeon retrospective review of early stage breast cancer lumpectomy patients treated from 1/2000 to 2/2005. Ductal endoscopy was used direct lumpectomy sur

BACKGROUND AND AIM: Ultralow anterior resection (uLAR) is a sphincter-saving procedure for very low-lying rectal cancers. This procedure, however, has complications related to defecation which can aggravate the patient's quality of life postoperatively. In this study, we compared the anthropometric and nutritional parameters after uLAR and abdominoperineal resection (APR). METHODS: We retrospectively reviewed the data of patients who underwent either uLAR or APR in 2012 for rectal cancers within

Importance: Colorectal cancer is a leading cause of cancer mortality, with increasing incidence in older adults. Oxaliplatin-based adjuvant chemotherapy is standard for stage II to III colorectal cancer, but its benefit in older patients remains unclear. Objective: To investigate whether there is an optimal age threshold for a survival benefit of adding oxaliplatin to fluoropyrimidine-based adjuvant chemotherapy in older patients with stage II to III colorectal cancer. Design, Setting, and Parti

PURPOSE: This study aimed to compare the short-term outcomes of the open and laparoscopic approaches to 2-stage restorative proctocolectomy (RPC) for Korean patients with ulcerative colitis (UC). METHODS: We retrospectively analyzed the medical records of 73 patients with UC who underwent elective RPC between 2009 and 2016. Patient characteristics, operative details, and postoperative complications within 30 days were compared between the open and laparoscopic groups. RESULTS: There were 26 case

This operative report documents the details of a surgery. Standardization of the medical terminology for the operative report written in free text is significant for performing medical research and establishing insurance systems by accurately sharing information on treatment. However, standardization of operative reports is a labor-intensive task that has a risk of induced errors. We have proposed a concatenation of bidirectional encoder representations from transformers (ConBERT) model for pred

Purpose: The role of paraaortic lymph node dissection (PALND) in colorectal cancer (CRC) has been less evaluated than surgical treatments for other distant metastases. We evaluated surgical outcomes after PALND and identified prognostic factors. Methods: The medical records of patients who underwent PALND for paraaortic lymph node metastasis (PALNM) were reviewed retrospectively. All patients were categorized into the M1a group (isolated PALNM, n = 27), and the M1bc group (distant metastases oth

PURPOSE: Neoadjuvant chemoradiotherapy has been accepted as a standard treatment for stage II-III rectal cancer. This study aimed to evaluate the clinical characteristics of patients who underwent neoadjuvant chemoradiotherapy for rectal cancer and effects on overall survival (OS) of neoadjuvant chemoradiotherapy in South Korea. METHODS: Patients who underwent curative resection for rectal cancer from 2014 to 2016 were retrospectively reviewed from the database of the National Quality Assessment
