Graphical Abstract 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.

Graphical Abstract 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.

Purpose
This study aimed to determine the effect of tumor resection on dysbiosis of the intestinal microbiota in patients with right-sided colon cancer.
Methods
This study utilized a longitudinal design to explore the outcomes of patients diagnosed with right-sided colon cancer who underwent surgical resection at Dr. M. Djamil General Hospital from July to December 2023. We excluded patients with a documented history of comorbidities, specifically those affecting the digestive system. To compare the microbiota (genus and phylum) between patients with right-sided colon cancer and the control group, we conducted bivariate analyses using the independent t-test or Mann-Whitney test. Furthermore, we employed the dependent t-test or Wilcoxon test to assess changes in the dysbiosis of the microbiota (genus and phylum) before and after resection. A P-value of <0.05 was considered statistically significant.
Results
This study included a total of 21 patients diagnosed with right-sided colon cancer. In the control group, Bacteroidetes constituted the highest proportion of intestinal microbiota, accounting for 56.34%. Prior to tumor resection, the intestinal microbiota of patients exhibited Proteobacteria as the predominant phylum, representing 52.97%. Following tumor resection, Bacteroidetes remained the most prevalent, comprising 50.9% of the intestinal microbiota. Significant variations in the levels of Proteobacteria, Verrucomicrobia, and Cyanobacteria/Chloroplast were observed in the intestinal microbiota of patients with right-sided colorectal cancer before and after tumor excision (all P=0.001).
Conclusion
The microbiome of patients with right-sided colorectal cancer differed significantly from that of the control group. However, following tumor resection, the microbiome composition of these patients became more similar to that observed in the control group.

Graphical Abstract Abstract PDF: Purpose
The standard treatment for locally advanced rectal cancer involves neoadjuvant chemoradiation followed by total mesorectal excision surgery. A subset of patients achieves pathologic complete response (pCR), representing the optimal treatment outcome. This study compares the long-term oncological outcomes of patients who achieved pCR with those who attained clinical complete response (cCR) after total neoadjuvant therapy, managed using a watch-and-wait approach.
Methods
This study retrospectively evaluated patients with mid-low locally advanced rectal cancer who underwent neoadjuvant treatment from January 1, 2005, to May 1, 2023. The pCR and cCR groups were compared based on demographic, clinical, histopathological, and long-term survival outcomes.
Results
The median follow-up times were 54 months (range, 7–83 months) for the cCR group (n=73), 96 months (range, 7–215 months) for the pCR group (n=63), and 72 months (range, 4–212 months) for the pathological incomplete clinical response (pICR) group (n=627). In the cCR group, 15 patients (20.5%) experienced local regrowth, and 5 (6.8%) developed distant metastasis (DM). The pCR group had no cases of local recurrence, but 3 patients (4.8%) developed DM. Among the pICR patients, 58 (9.2%) experienced local recurrence, and 92 (14.6%) had DM. Five-year disease-free survival rates were 90.0% for cCR, 92.0% for pCR, and 69.5% for pICR (P=0.022). Five-year overall survival rates were 93.1% for cCR, 92.0% for pCR, and 78.1% for pICR. There were no significant differences in outcomes between the cCR and pCR groups (P=0.810); however, the pICR group exhibited poorer outcomes (P=0.002).
Conclusion
This study shows no significant long-term oncological differences between patients who exhibited cCR and those who experienced pCR.

Graphical Abstract Abstract PDF

Purpose
Continuous wound infiltration (CWI) has been introduced as a component of multimodal analgesia to counteract the adverse effects of the most frequently used opioids. Advantages of reduced-port laparoscopic surgery (RPLS) include cosmetic benefits and decreased postoperative pain. We aimed to investigate the effect of CWI in patients using intravenous (IV) patient-controlled analgesia (PCA) for pain management after RPLS for colorectal cancer.
Methods
This retrospective study included 25 patients who received both CWI (0.5% ropivacaine infused over 72 hours) and IV PCA (fentanyl citrate) and 52 patients who received IV PCA alone. The primary endpoint was pain scores on postoperative days (PODs) 0, 1, and 2. Univariate and multivariate analyses were conducted to determine the factors affecting the pain score on POD 0.
Results
On POD 0, the mean numeric rating scale score was significantly lower in the CWI group than in the control group (3.2±0.8 vs. 3.7±0.9, P=0.042). However, the scores were comparable between the groups during the rest of the period. Within 24 hours of surgery, the CWI group consumed fewer opioids (0.7±0.9 vs. 1.3±1.1, P=0.018) and more nonsteroidal anti-inflammatory drugs (2.0±1.4 vs. 1.3±1.4, P=0.046) than the control group. Time to removal of IV PCA was significantly longer in the CWI group than in the control group (4.4±1.6 days vs. 3.4±1.0 days, P=0.016).
Conclusion
CWI with ropivacaine and IV PCA was more effective than IV PCA alone in controlling postoperative pain within 24 hours of surgery, and opioid use could be reduced further.

Graphical Abstract Abstract PDF: Purpose
This study aimed to demonstrate the safety of new double-stapling technique (nDST), without a crossing line and dog ears, by comparing with conventional DST (cDST) in laparoscopic low anterior resection (LAR).
Methods
We retrospectively reviewed 98 consecutive patients who underwent laparoscopic LAR for rectal cancer from January 2018 to December 2020. The inclusion criterion was an anastomosis level below the peritoneal reflection and 4 cm above the anal verge. In the nDST group, the staple line of the linear cutter was sutured using barbed sutures to shorten the staple line before firing the circular stapler. Therefore, there were no crossing lines after firing the circular stapler. A 2:1 propensity score matching was performed between the cDST and nDST groups.
Results
After propensity score matching, 39 patients were in the cDST group and 20 were in the nDST group. There were no significant differences in patient demographics between the 2 groups. There was no difference in the total operation time between the cDST and nDST groups (124.0±26.2 minutes vs. 125.2±20.3 minutes, P=0.853). Morbidity rates were similar between the 2 groups (9 cases [23.1%] vs. 5 cases [25.0%], P=0.855). There was no significant difference in leakage rate (4 cases [10.3%] vs. 1 case [5.0%], P=0.847) and anastomotic bleeding rate (1 case [2.6%] vs. 3 cases [15.0%], P=0.211).
Conclusion
The nDST to eliminate the crossing line and dog ears in laparoscopic LAR is technically feasible and safe. However, more attention should be paid to anastomotic bleeding in such cases.

Graphical Abstract Abstract PDF

Purpose
We aimed to develop a predictive tool for anastomotic leakage (AL) following colon cancer surgery by combining a clinical early warning score (EWS) with the C-reactive protein (CRP) level.
Methods
The records of 1,855 patients who underwent colon cancer surgery at the Oxford University Hospitals NHS Foundation Trust between January 2013 and December 2018, with or without AL, were retrospectively reviewed. EWS and CRP levels were assessed daily from the first postoperative day until discharge. AL was defined as an anastomotic defect observed at reoperation, the presence of feculent fluid in a pelvic drain, or evidence of AL on computed tomography. The tool incorporated postoperative EWS and CRP levels for the accurate early detection of AL.
Results
From postoperative days 3 to 7, the mean CRP level exceeded 200 mg/L in patients with AL and was under 200 mg/L in those without AL (P<0.05). From postoperative days 1 to 5, the mean EWS among patients with leakage exceeded 2, while scores were below 2 among those without leakage (P<0.05). Receiver operating characteristic curve analysis identified postoperative day 3 as the most predictive of early leakage, with cutoff values of 2.4 for EWS and 180 mg/L for CRP; this yielded an area under the curve of 0.87 (sensitivity, 90%; specificity, 70%).
Conclusion
We propose using an EWS of 2.4 and a CRP level of 180 mg/L on postoperative day 3 following colon surgery with anastomosis as threshold values to prompt investigation and treatment of AL.

Purpose
Enhanced Recovery After Surgery (ERAS) reduces postoperative complications (POCs) after colorectal surgery; however, its impact on the management of POCs remains unclear. This study compared the diagnosis and management of POCs before and after implementing our ERAS protocol after laparoscopic or robotic colectomy for cancer and examined the short- and mid-term oncologic impacts.
Methods
This single-center, retrospective study evaluated all consecutive patients who underwent laparoscopic or robotic colectomy for cancer between 2012 and 2021, focusing on the incidence of POCs within 90 days. We compared outcomes before (standard group) and after (ERAS group) the implementation of our ERAS protocol in January 2016.
Results
Significantly fewer patients in the ERAS group developed POCs (standard vs. ERAS, 136 of 380 patients [35.8%] vs.136 of 660 patients [20.6%]; P<0.01). The ERAS group had a significantly shorter mean total length of stay after POCs (13.1 days vs. 11.4 days, P=0.04), and the rates of life-threatening complications (6.7% vs. 0.7%) and 1-year mortality (7.4% vs. 1.5%) were significantly lower in the ERAS group than in the standard group. Among patients with anastomotic complications, laparoscopic reoperation was significantly more common in the ERAS group than in the standard group (8.3% vs. 75.0%, P<0.01). Among patients with postoperative ileus, the diagnosis and recovery times were significantly shorter in the ERAS group than in the standard group, resulting in a shorter total length of stay (13.5 days vs. 10 days, P<0.01).
Conclusion
The implementation of an ERAS protocol did not eliminate all POCs, but it did accelerate their diagnosis and management and improved patient outcomes.

Purpose
As introduced, multimodal pain management bundle for ileostomy reversal may be considered to reduce postoperative pain and hospital stay. The aim of this study was to evaluate clinical efficacy of perioperative multimodal pain bundle for ileostomy.
Methods
Medical records of patients who underwent ileostomy reversal after rectal cancer surgery from April 2017 to March 2020 were analyzed. Sixty-seven patients received multimodal pain bundle protocol with ileostomy reversal (group A) and 41 patients underwent closure of ileostomy with conventional pain management (group B).
Results
Baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists classification, diabetes mellitus, and smoking history, were not significantly different between the groups. The pain score on postoperative day 1 was significant lower in group A (visual analog scale, 2.6 ± 1.3 vs. 3.2 ± 1.2; P = 0.013). Overall consumption of opioid in group A was significant less than group B (9.7 ± 9.5 vs. 21.2 ± 8.8, P < 0.001). Hospital stay was significantly shorter in group A (2.3 ± 1.5 days vs. 4.1 ± 1.5 days, P < 0.001). There were no significant differences between the groups in postoperative complication rate.
Conclusion
Multimodal pain protocol for ileostomy reversal could reduce postoperative pain, usage of opioid and hospital stay compared to conventional pain management.

Purpose
Preoperative colonoscopic (POC) localization is recommended for patients scheduled for elective laparoscopic colectomy for early colon cancer. Among the various localization method, POC tattooing localization has been widely used. Several dyes have been used for tattooing, but dye has disadvantages, including foreign body reactions. For this reason, we have used autologous blood tattooing for POC localization. This study aimed to evaluate the safety and efficacy of the autologous blood tattooing method.
Methods
This study included patients who required POC localization of the colonic neoplasm among the patients who were scheduled for elective colon resection. The indication for localization was early colon cancer (clinically T1 or T2) or colonic neoplasms that could not be resected endoscopically. POC autologous blood tattooing was performed after saline injection, and 2 hemoclips were applied.
Results
A total of 45 patients who underwent autologous blood tattooing and laparoscopic colectomy were included in this study. All POC localization sites were visible in the laparoscopic view. POC localization sites showed almost perfect agreement with intraoperative surgical findings. There were no complications like bowel perforation, peritonitis, hemoperitoneum, and mesenteric hematoma.
Conclusion
Autologous blood is a safe and effective agent for localizing materials that can replace previous dyes. However, a large prospective case-control study is required for the routine application of this procedure in early colon cancer or colonic neoplasms.

Purpose
Incisional hernia (IH) is a frequent complication following laparoscopic colorectal surgery. The present study investigated the risk factors for IH after laparoscopic surgery for colorectal cancer.
Methods
A retrospective study was conducted on 202 patients who underwent laparoscopic surgery for colorectal cancer. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with IH.
Results
The overall incidence of IH was 25.7% (52 of 202). The univariate analysis showed that female sex (P=0.004), a high body mass index (P<0.001), noncurrent smoking habit (P=0.043), low level of hemoglobin (P=0.035), high subcutaneous fat area (P<0.001), high visceral fat area (P=0.006), low skeletal muscle area (P=0.001), long distance between the inner edges of the rectus abdominis muscle (P=0.001), long protrusion of the peritoneum at the umbilical site (P<0.001), and lymph node metastasis (P=0.007) were significantly more frequent in the group with IH than in the group without it. The multivariate logistic regression analysis revealed an older age (10-year increments: odds ratio [OR], 1.576; 95% confidence interval [CI], 1.027–2.419; P=0.037), lymph node metastasis (OR, 2.384; 95% CI, 1.132–5.018; P=0.022) and lengthy protrusion of the peritoneum at the umbilical site (10-mm increments: OR, 5.555; 95% CI, 3.058–10.091; P<0.001) were independent risk factors for IH.
Conclusion
Our findings suggest that older age, lymph node metastasis, and lengthy protrusion of the peritoneum at the umbilical site are risk factors for IH after laparoscopic surgery for colorectal cancer. An assessment using these factors before the operation and the implementation of countermeasures might help prevent IH.

Purpose
The Korean Society of Coloproctology has been conducting Colorectal Cancer Awareness Campaign, also known as the Gold Ribbon Campaign, every September since 2007. The 2022 campaign was held through a metaverse platform targeting the younger age group under the slogan of raising awareness of early-onset colorectal cancer (CRC). This study aimed to analyze the impact of the 2022 campaign on a metaverse platform.
Methods
Anonymized survey data were collected from participants in the metaverse campaign from September 1 to 15, 2022. The satisfaction score of the participants was evaluated by sex, age group, and previous campaign participation status.
Results
During the campaign, 2,770 people visited the metaverse. Among them, 455 people participated in the survey (response rate, 16.4%). Approximately 95% of the participants reported being satisfied with the information provided by the campaign, understood the necessity of undergoing screening for and prevention of early-onset CRC, and were familiar with the structure of the metaverse. The satisfaction score for campaign information tended to decrease as the participants’ age increased. When the participants’ overall level of satisfaction with the metaverse platform was assessed, teenagers scored particularly lower than the other age groups. The satisfaction scores for CRC information provided in the metaverse, as well as the scores for recognizing the seriousness and necessity of screening for early-onset CRC, indicated a high positive tendency (P<0.001).
Conclusion
Most of the 2022 Gold Ribbon Campaign participants were satisfied with the metaverse platform. Medical society should pay attention to increasing participation in and satisfaction with future public campaigns.

Purpose
Traditional therapeutic approaches to the surgical management of hemorrhoid disease such as hemorrhoidectomies are plagued with severe postoperative pain and protracted recovery. Our pilot study aims to the laser hemorrhoidoplasty (LH) patients with symptomatic hemorrhoid disease that have failed conservative management for the first time in an Australian population.
Methods
Thirty patients were prospectively enrolled to undergo LH. Postoperative pain, time to return to function, and quality of life (QoL) were determined through the Hemorrhoid Disease Symptom Score and Short Health Scale adapted for hemorrhoidal disease and compared to a historical group of 43 patients who underwent a Milligan-Morgan hemorrhoidectomy by the same surgeon at 3, 6, and 12 months.
Results
The LH group had significantly lower mean predicted pain scores on days 1 and 2 and lower defecation pain scores and lower opioid analgesia use on days 1, 2, 3, and 4. The median time to return to normal function was significantly lower in the LH group (2 days vs. 9 days, P<0.001). Similarly, the median days to return to the workplace was significantly lower in the LH group (6 days vs. 13 days, P=0.007). During long-term follow-up (12 months), hemorrhoid symptoms and all QoL measures were significantly improved, especially among those with grade II to III disease.
Conclusion
This pilot study demonstrates low pain scores with this revivified procedure in an Australian population, indicating possible expansion of the therapeutic options available for this common condition. Further head-to-head studies comparing LH to other hemorrhoid therapies are required to further determine the most efficacious therapeutic approach.

Purpose
This study aimed to evaluate the long-term clinical outcomes based on the ligation level of the inferior mesenteric artery (IMA) in patients with rectal cancer.
Methods
This was a retrospective analysis of a prospectively collected database that included all patients who underwent elective low anterior resection for rectal cancer between January 2013 and December 2019. The clinical outcomes included oncological outcomes, postoperative complications, and functional outcomes. The oncological outcomes included overall survival (OS) and relapse-free survival (RFS). The functional outcomes, including defecatory and urogenital functions, were analyzed using the Fecal Incontinence Severity Index, International Prostate Symptom Score, and International Index of Erectile Function questionnaires.
Results
In total, 545 patients were included in the analysis. Of these, 244 patients underwent high ligation (HL), whereas 301 underwent low ligation (LL). The tumor size was larger in the HL group than in the LL group. The number of harvested lymph nodes (LNs) was higher in the HL group than in the LL group. There were no significant differences in complication rates and recurrence patterns between the groups. There were no significant differences in 5-year RFS and OS between the groups. Cox regression analysis revealed that the ligation level (HL vs. LL) was not a significant risk factor for oncological outcomes. Regarding functional outcomes, the LL group showed a significant recovery in defecatory function 1 year postoperatively compared with the HL group.
Conclusion
LL with LNs dissection around the root of the IMA might not affect the oncologic outcomes comparing to HL; however, it has minimal benefit for defecatory function.

Graphical Abstract Abstract PDF Supplementary Material: Purpose
Blood transfusion is one of the most common procedures used to treat anemia in colorectal surgery. Despite controversy regarding the adverse effects of blood products, surgeons have maintained standards for administering blood transfusions. However, this trend was restrictive during the COVID-19 pandemic because of a shortage of blood products. In this study, we conducted an analysis to investigate whether the restriction of blood transfusions affected postoperative surgical outcomes.
Methods
Medical records of 318 patients who underwent surgery for colon and rectal cancer at Ewha Womans University Mokdong Hospital between June 2018 and March 2022 were reviewed retrospectively. The surgical outcomes between the liberal and restrictive transfusion strategies in pre– and post–COVID-19 groups were analyzed.
Results
In univariate analysis, postoperative transfusion was associated with infectious complications (odds ratio [OR], 1.705; 95% confidence interval [CI], 1.015–2.865; P=0.044). However, postoperative transfusion was not an independent risk factor for the development of infectious complications in multivariate analysis (OR, 1.305; 95% CI, 0.749–2.274; P=0.348). In subgroup analysis, there was no significant association between infectious complications and the hemoglobin threshold level for the administration of a transfusion (OR, 1.249; 95% CI, 0.928–1.682; P=0.142).
Conclusion
During colorectal surgery, the decision to perform a blood transfusion is an important step in ensuring favorable surgical outcomes. According to the results of this study, restrictive transfusion is sufficient for favorable surgical outcomes compared with liberal transfusion. Therefore, modification of guidelines is suggested to minimize unnecessary transfusion-related side effects and prevent the overuse of blood products.
