Abstract PDF Supplementary Material: Purpose
The technique for transanal resection of rectal tumors has evolved from conventional methods to minimally invasive approaches. However, the research comparing long-term results between these approaches is limited.
Methods
Between 2016 and 2022, a total of 133 patients who underwent transanal excision were analyzed. Patients were classified into 2 groups according to surgical approach: conventional transanal approach (CTA) and minimally invasive transanal approach (MTA). Medical records were analyzed to compare surgical and oncological outcomes between the 2 groups.
Results
There were no significant differences observed in patient’s demographics and tumor characteristics, except the MTA group exhibited a statistically longer distance from the anal verge. Although statistical significance was not reached, the MTA group demonstrated a 100% margin-negative rate in contrast to the CTA group, which had worse outcomes for both margin status and fragmentation. Recurrence was observed only in the CTA group containing pT1 rectal cancer and grade 1 neuroendocrine tumor, with negative margins and no fragmentation.
Conclusion
The minimally invasive approach did not demonstrate statistical superiority but showed technical feasibility through the absence of margin-positive cases and the use of the clip handle method. Further studies are needed to validate these findings and assess broader applicability.

Abstract PDF: Purpose
This study aimed to compare the wound cosmesis of a single-incision approach on scar assessment after laparoscopic surgery for colon cancer.
Methods
This study included 32 patients undergoing single-port laparoscopic surgery (SPLS) and 61 patients undergoing multiport laparoscopic surgery (MPLS) for colon cancer at 3 tertiary referral hospitals between September 2011 and December 2019. We modified and applied the Korean version of the Patient and Observer Scar Assessment Scale (POSAS) to assess cosmetic outcomes. To assess the interobserver reliability using intraclass correlation coefficient values for the Observer Scar Assessment Scale (OSAS), the surgeons evaluated 5 images of postoperative scars.
Results
No significant differences were observed in the time before the return of normal bowel function, time to sips of water and soft diet initiation, length of in-hospital stay, and postoperative complication rate. The SPLS group had a shorter total incision length than the MPLS group. The POSAS favored the SPLS approach, revealing significant differences in the Patient Scar Assessment Scale (PSAS), OSAS, and overall scores. The SPLS approach was an independent factor influencing the POSAS, PSAS, and OSAS scores. Eleven colorectal surgeons had a significantly substantial intraclass coefficient.
Conclusion
The cosmetic outcomes of SPLS as assessed by the patients and surgeons were superior to those of MPLS in colon cancer. Reducing the number of ports is an independent factor affecting scar assessment by patients and observers.

Abstract PDF Supplementary Material: Purpose
Colorectal cancer (CRC) is the most common malignancy of the gastrointestinal system globally. Identifying specific gene expression patterns indicative of early-stage CRC could enable early diagnosis and rapid treatment initiation. Matrix metalloproteinases (MMPs) play crucial roles in extracellular matrix degradation and tissue remodeling. Among them, MMP-2 and MMP-9 have been found to be upregulated in various cancers, including CRC, and are associated with tumor invasion, metastasis, and angiogenesis. In contrast, a disintegrin and metalloproteinase like decysin 1 (ADAMDEC1) is a relatively newly discovered gene with demonstrated involvement in immune response and inflammation. This study investigated serum levels of MMP-2 and MMP-9, along with tissue expression of MMP-2, MMP-9, and ADAMDEC1, and explored potential associations with pathological and clinical factors in patients with CRC.
Methods
This study included 100 patients with CRC and 100 control participants. Tissue and blood samples were collected. Serum MMP-2 and MMP-9 levels were analyzed using the enzyme-linked immunosorbent assay. Quantitative real-time polymerase chain reaction was employed to assess the expression levels of MMP-2, MMP-9, and ADAMDEC1 in CRC tissue samples compared to adjacent control tissue.
Results
The expression levels of MMP-2, MMP-9, and ADAMDEC1 were significantly upregulated in CRC relative to adjacent control tissues. Analysis of clinicopathological features revealed statistically significant differences in the expression levels of MMP-2, MMP-9, and ADAMDEC1 between patients with CRC with and without lymphovascular invasion (P<0.001). Based on receiver operating characteristic curve analysis, these genes represent promising candidate diagnostic biomarkers for CRC.
Conclusion
MMP-2, MMP-9, and ADAMDEC1 levels may serve as potential diagnostic biomarkers for CRC.

A comparative study on efficacy and safety of modified partial stapled hemorrhoidopexy versus conventional hemorrhoidectomy: a prospective randomized controlled trial: Tae Gyu Kim, Chul Seung Lee, Dong Geun Lee, Choon Sik Chung, Seung Han Kim, Sang Hwa Yu, Jeong Eun Lee, Gwan Cheol Lee, Dong Woo Kang, Jeong Sub Kim, Gyu Young Jeong; Received August 13, 2024 Accepted November 24, 2024 Published online April 28, 2025; DOI: https://doi.org/10.3393/ac.2024.00535.0076 [Epub ahead of print]

Abstract PDF Supplementary Material: Purpose
The long-term outcomes and efficacy of partial stapled hemorrhoidopexy (PSH) compared with those of conventional hemorrhoidectomy (CH) are not fully understood. This study aimed to introduce a modified PSH (mPSH) and compare its clinical efficacy and safety with those of CH.
Methods
A prospective randomized controlled trial was conducted. This study was performed at a single hospital and involved 6 colorectal surgeons. In total, 110 patients were enrolled between July 2019 and September 2020. Patients were randomly assigned to undergo either mPSH group (n=55) or CH group (n=55). The primary outcome was to compare postoperative average pain and postoperative peak pain using visual analog scale score between the 2 groups.
Results
The required duration of analgesia was shorter in the mPSH group than in the CH group, although the difference was not statistically significant (P=0.096). However, the laxative requirement duration (P<0.010), return to work (P<0.010), satisfaction score (P<0.010), and Vaizey score (P=0.014) were significantly better in the mPSH group. The average and peak postoperative pain scores were significantly lower in the mPSH group during the 15 days after surgery (P<0.001). The overall complication rate in both groups was 9.1%, with no significant difference between the groups (P=0.867).
Conclusion
The mPSH group demonstrated better improvement in symptoms, lower pain scores, and greater patient early satisfaction after surgery than the CH group. Therefore, this surgical technique appears to be a safe and effective alternative for CH.

Impact of iron-deficiency anemia on short-term outcomes after resection of colorectal cancer liver metastasis: a US National (Nationwide) Inpatient Sample (NIS) analysis: Ko-Chao Lee, Yu-Li Su, Kuen-Lin Wu, Kung-Chuan Cheng, Ling-Chiao Song, Chien-En Tang, Hong-Hwa Chen, Kuan-Chih Chung; Received September 3, 2024 Accepted December 30, 2024 Published online April 24, 2025; DOI: https://doi.org/10.3393/ac.2024.00591.0084 [Epub ahead of print]

Abstract PDF Supplementary Material: Purpose
Colorectal cancer (CRC) often spreads to the liver, necessitating surgical treatment for CRC liver metastasis (CRLM). Iron-deficiency anemia is common in CRC patients and is associated with fatigue and weakness. This study investigated the effects of iron-deficiency anemia on the outcomes of surgical resection of CRLM.
Methods
This population-based, retrospective study evaluated data from adults ≥20 years old with CRLM who underwent hepatic resection. All patient data were extracted from the 2005–2018 US National (Nationwide) Inpatient Sample (NIS) database. The outcome measures were in-hospital outcomes including 30-day mortality, unfavorable discharge, and prolonged length of hospital stay (LOS), and short-term complications such as bleeding and infection. Associations between iron-deficiency anemia and outcomes were determined using logistic regression analysis.
Results
Data from 7,749 patients (representing 37,923 persons in the United States after weighting) were analyzed. Multivariable analysis revealed that iron-deficiency anemia was significantly associated with an increased risk of prolonged LOS (adjusted odds ratio [aOR], 2.76; 95% confidence interval [CI], 2.30–3.30), unfavorable discharge (aOR, 2.42; 95% CI, 1.83–3.19), bleeding (aOR, 5.05; 95% CI, 2.92–8.74), sepsis (aOR, 1.60; 95% CI, 1.04–2.46), pneumonia (aOR, 2.54; 95% CI, 1.72–3.74), and acute kidney injury (aOR, 1.71; 95% CI, 1.24–2.35). Subgroup analyses revealed consistent associations between iron-deficiency anemia and prolonged LOS across age, sex, and obesity status categories.
Conclusion
In patients undergoing hepatic resection for CRLM, iron-deficiency anemia is an independent risk factor for prolonged LOS, unfavorable discharge, and several critical postoperative complications. These findings underscore the need for proactive anemia management to optimize surgical outcomes.

Abstract PDF: Appendectomy as the standard treatment for acute appendicitis has been challenged by accumulating evidence supporting nonoperative management with antibiotics as a potential primary treatment. This review aimed to summarize the clinical outcomes and the optimal indications for nonoperative management of acute appendicitis in adults. Current evidence suggests that uncomplicated and complicated appendicitis have different pathophysiologies and should be treated differently. Nonoperative management for uncomplicated appendicitis was not inferior to appendectomy in terms of complications and length of stay, with less than a 30% failure rate at 1 year. The risk of perforation and postoperative complications did not increase even if nonoperative management failed. Complicated appendicitis with localized abscess or phlegmon could also be treated conservatively, with a success rate of more than 80%. An interval appendectomy following successful nonoperative management is recommended only for patients over the age of 40 years to exclude appendiceal malignancy. The presence of appendicoliths increased the risk of treatment failure and complications; thus, it may be an indication for appendectomy. Nonoperative management is a safe and feasible option for both uncomplicated and complicated appendicitis. Patients should be informed that nonoperative management may be a safe alternative to surgery, with the possibility of treatment failure.

Abstract PDF: Purpose
Early diagnosis of anastomotic leakage (AL) after colorectal surgery can reduce severe postoperative morbidity and ensure successful treatment. This study evaluated the feasibility of bedside endoscopic inspection of the anastomosis early postoperatively using a point-of-care digital rectoscope.
Methods
This prospective study was conducted at 2 tertiary centers. Patients who underwent minimally invasive or open sphincter-preserving surgery with creation of a colorectal or coloanal anastomosis were included. Data were collected from December 2022 to October 2023. Bedside anastomotic inspections were performed postoperative day (POD) 3 to 5 using a point-of-care digital rectoscope. The primary outcome was feasibility, defined as adequate clinical assessment of the anastomosis during bedside inspection. Secondary outcomes included patient tolerability, efficacy compared to other diagnostic methods, and clinical outcomes during 90 days of follow-up.
Results
In total, 35 patients were included. All bedside anastomotic inspections were carried out successfully. The examination showed complete visibility of the entire anastomosis in 30 patients (85.7%), with minimal discomfort reported by 3 (8.6%). No adverse events were recorded. AL occurred in 6 patients (17.1%), with 3 cases detected during bedside inspections between POD 3 and 5. Two leaks were detected without clinical or biochemical suspicion. Three patients with negative rectoscopy between POD 3 and 5 were later diagnosed with AL: 2 by a computed tomography scan and 1 by a bedside rectoscopy.
Conclusion
Bedside inspection of rectal anastomoses early postoperatively is feasible and tolerable for patients. Routine anastomotic inspections can detect early AL even without clear clinical or biochemical signs.

Purpose
The aim of this study was to examine the prognosis and associated risk factors, including adjuvant chemotherapy (CTx), in elderly patients with colon cancer.
Methods
This retrospective study included patients who underwent radical resection for colon cancer between January 2010 and December 2014 at Asan Medical Center. The effects of stage, risk factors, and chemotherapy on overall survival (OS) and recurrence-free survival (RFS) were compared in patients aged ≥70 and <70 years.
Results
Of 3,313 patients, 933 (28.1%) was aged ≥70 years. Of the 1,921 patients indicated for adjuvant CTx, 1,294 of 1,395 patients (92.8%) aged <70 years and 369 of 526 patients (70.2%) aged ≥70 years received adjuvant CTx. Old age (≥70 years) was independently associated with RFS in overall cohort. Among patients aged ≥70 years indicated for adjuvant CTx, the 5-year OS (81.6% vs. 50.4%, P<0.001) and RFS (82.9% vs. 67.4%, P=0.025) rates were significantly higher in those who did than did not receive adjuvant CTx. Additionally, adjuvant CTx was confirmed as independent risk factor of both OS and RFS in patients aged ≥70 years indicated for adjuvant CTx.
Conclusion
Old age was associated with poor RFS and adjuvant CTx had benefits in OS as well as RFS in elderly patients eligible for adjuvant CTx.

Abstract PDF

Purpose
This study was performed to assess the long-term annual functional outcomes and quality of life (QOL) after transanal rectocele repair.
Methods
We evaluated retrospectively collected data from patients who underwent transanal repair for symptomatic rectocele between February 2012 and December 2018. The Constipation Scoring System (CSS), the Fecal Incontinence Severity Index (FISI), and several QOL questionnaires (e.g., the Patient Assessment of Constipation-QOL [PAC-QOL], Fecal Incontinence QOL, and the 36-Item Short Form Survey [SF-36]) were administered before surgery and annually after surgery. Additionally, physiological assessments and defecography were performed before and after surgery. Substantial symptom improvement, indicated by at least a 50% reduction in the CSS or FISI score, was evaluated postoperatively. All postoperative follow-up results were compared with the preoperative data.
Results
Thirty-two patients were included in the study. The median follow-up period was 5 years (range, 0.5−7 years). Postoperative defecography showed that the rectocele size significantly decreased (P<0.0001). However, the physiological assessment did not reveal postoperative changes. The CSS score 1 year after surgery was significantly lower than the preoperative score (P<0.0001) and remained significantly low until the long-term follow-up. Constipation improved by more than 80% 2 to 5 years postoperatively, and fecal incontinence improved in 2/3 of the patients after 5 years. The PAC-QOL scores significantly improved (all P<0.05) over time until the 3-year and long-term follow-ups, and 6 of the 8 SF-36 scores significantly improved at specific points postoperatively.
Conclusion
Transanal rectocele repair provides long-term improvement for constipation and constipation-specific QOL.

Purpose
Bacteriological sample in the presence of intra-abdominal free fluid is necessary to adapt the antibiotherapy and to prevent the development of resistance. The aim was to evaluate the differences between uncomplicated acute appendicitis (UAA) and complicated acute appendicitis (CAA) in terms of bacterial culture results and antibiotic resistance, and to evaluate the factors linked with CAA.
Methods
We performed a single-center, retrospective observational study of all consecutive patients who presented with appendicular peritonitis and underwent emergent surgery in a tertiary referral hospital in Brussels, Belgium, between January 2013 and December 2020. The medical history, parameters at admission, bacterial culture, antibiotic resistance, and postoperative outcomes of 268 patients were analyzed. UAA was considered catarrhal or phlegmonous inflammation of the appendix. CAA was considered gangrenous or perforated appendicitis.
Results
Positive microbiological cultures were significantly higher in the CAA group (68.2% vs. 53.4%). The most frequently isolated bacteria in UAA and CAA cultures were Escherichia coli (37.9% and 48.6%, respectively). Most observed resistances were against ampicillin (28.9% and 21.7%) and amoxicillin/clavulanic acid (16.4% and 10.5%) in UAA and CAA, respectively. A higher Charlson Comorbidity Index, an elevated white blood cell count, an open procedure, and the need for drainage were linked to CAA. Culture results, group of bacterial isolation, and most common isolated bacteria were not related to CAA.
Conclusion
CAA presented a higher rate of positive cultures with increased identification of gram-negative bacteria. Bacterial culture from the peritoneal liquid does not reveal relevant differences in terms of antibiotic resistance.

Abstract PDF

Purpose
Retrorectal tumors (RTs) are rare tumors that arise in the space between the mesorectum and the pelvic wall and often originate in embryonic tissues. The primary treatment for these tumors is complete excision surgery, and choosing the best surgical approach is very important.
Methods
In this study, we retrospectively collected the data of 15 patients with RTs who underwent surgery in Imam Khomeini Hospital (Tehran, Iran) for 12 years to share our experiences of patients’ treatment and compare different surgical approaches.
Results
A total of 5 tumors were malignant, 10 were benign, and most of the tumors were congenital. Malignant tumors were seen in older patients. Three surgical procedures were performed on patients. Three patients underwent abdominal approach surgery, and 8 patients underwent posterior surgery. A combined surgical approach was performed on 4 patients. Two patients underwent laparoscopic surgery. The abdominal approach had the least long-term complication, and the combined approach had the most complications; laparoscopic surgery reduced the length of hospital stay and complications after surgery.
Conclusion
A multidisciplinary team collaboration using magnetic resonance imaging details is necessary to determine a surgical treatment approach. It could reduce the need for a preoperative biopsy. However, every approach has its advantages and disadvantages, and individualized treatment is the key.

Abstract PDF

Purpose
Our aim was to evaluate the effectiveness of combining fissurectomy with botulinum toxin A injection in treating chronic anal fissures.
Methods
A single surgeon in Saudi Arabia conducted a nonrandomized prospective cohort study between October 2015 and July 2020. The cohort included 116 female patients with chronic anal fissures, with a mean age of 36.57±11.52 years, who presented to the surgical outpatient clinic and received a botulinum toxin injection combined with fissurectomy. They were followed up with at 1, 2, 3, 4, and 8 weeks to evaluate the effects of the treatment, then again at 1 year. The primary outcome measures were symptomatic relief, complications, recurrence, and the need for further surgical intervention.
Results
Treatment with botulinum toxin A combined with fissurectomy was effective in 99.1% of patients with chronic anal fissures at 1 year. Five patients experienced recurrence at 8 weeks, which resolved completely with a pharmacological sphincterotomy. Twelve patients experienced minor incontinence, which later disappeared. Pain completely disappeared in more than half of the patients (55.2%) within 7 to 14 days. Pain started to improve in less than 8 days among patients treated with a dose of 50±10 IU (P=0.002).
Conclusion
Seventy units of botulinum toxin A injection combined with a fissurectomy is a suitable second-line treatment of choice for chronic anal fissures, with a high degree of success and low rate of major morbidity.
