Purpose
To assess the efficacy of total neoadjuvant therapy (TNT) for rectal carcinoma in comparison with conventional chemoradiotherapy (CRT).
Methods
A systematic review was performed according to the PRISMA guidelines. A Bayesian network meta-analysis was done using NetMetaXL and WinBUGS. This study was registered in PROSPERO on March 3, 2022 (No. CRD-42022307867).
Results
Outcomes of 2,719 patients from 10 randomized trials between 2010 and 2022 were selected. Of these 1,191 (44%) had conventional long-course CRT (50–54 Gy) and capecitabine, 506 (18%) had induction chemotherapy followed by CRT (50–54 Gy) and capecitabine (iTNT), 230 (9%) had long-course CRT (50–54 Gy) followed by consolidation chemotherapy (cTNT), and 792 (29%) undergone modified short-course radiotherapy (25 Gy) with subsequent chemotherapy (mTNT). Total pathologic complete response (pCR) was 20% in the iTNT group, 21% in the mTNT group, 22% in the cTNT group, and 12% in the CRT group. Statistically significant difference in pCR rates was detected when comparing iTNT with CRT (odds ratio [OR], 1.76; 95% credible interval [CrI], 1.06–2.8), mTNT with CRT (OR, 1.90; 95% CrI, 1.25–2.74), and cTNT with CRT groups (OR, 2.54; 95% CrI, 1.26–5.08). No differences were found in R0 resection rates. No significant difference was found in long-term outcomes.
Conclusion
The early administration of systemic chemotherapy in the TNT regimen has improved short-term outcomes, though long-term results are underreported. Randomized trials with survival as the endpoint are necessary to evaluate the possible advantages of TNT modes.

Abstract PDF

Recent advances in the management of rectal cancer have dramatically changed the clinical practice of colorectal surgeons because the main focus of rectal cancer treatment has changed from sphincter-saving to an organ-preserving strategies. Modifying the delivery of systemic chemotherapy to improve patients’ survival is another progress in colorectal cancer management, known as total neoadjuvant therapy (TNT). TNT is a new strategy used by colorectal surgeons to improve the quality of life and survival of patients after treatment. TNT poses limitations or obstacles, such as overtreatment issues in patients with stage I rectal cancer. However, considering the quality-of-life issues in patients with low-lying rectal cancer necessitating a permanent colostomy, the indication for TNT will be expanded. This review summarizes the recently conducted clinical trials and foresees future perspectives on TNT.

Purpose
Rectal cancer treatment has a wide range of possible approaches from radical extirpative surgery to nonoperative watchful waiting following chemoradiotherapy, with or without, additional chemotherapy. Our goal was to assess the personal opinion of active practicing surgeons on rectal cancer treatment if he/she was the patient.
Methods
A panel of the International Society of University Colon and Rectal Surgeons (ISUCRS) selected 10 questions that were included in a questionnaire that included other items including demographics. The questionnaire was distributed electronically to ISUCRS fellows and other surgeons included in our database and remained open from April 16 to 28, 2020.
Results
One hundred sixty-three specialists completed the survey. The majority of surgeons (n=65, 39.9%) chose the minimally invasive (laparoscopic) surgery for their personal treatment of rectal cancer. For low-lying rectal cancer T1 and T2, the treatment choice was standard chemoradiation+local excision (n=60, 36.8%) followed by local excision±chemoradiotherapy if needed (n=55, 33.7%). In regards to locally advanced low rectal cancer T3 or greater, the preference of the responders was for laparoscopic surgery (n=65, 39.9%). We found a statistically significant relationship between surgeons’ age and their preference for minimally invasive techniques demonstrating an age-based bias on senior surgeons’ inclination toward open approach.
Conclusion
Our survey reveals an age-based preference by surgeons for minimally invasive surgical techniques as well as organ-preserving techniques for personal treatment of treating rectal cancer. Only 1/4 of specialists do adhere to the international guidelines for treating early rectal cancer.

Graphical Abstract Abstract PDF

Purpose
C-reactive protein to albumin ratio (CAR) has been utilized as a prognostic factor in various carcinomas. We investigated the relationship between preoperative, postoperative day (POD) 1, and POD 7 CARs and the prognosis of patients with colorectal cancer (CRC).
Methods
Three hundred twenty patients with CRC who underwent laparoscopic radical resection between May 2011 and December 2016 were enrolled. Patients were selected into 2 groups, high CAR and low CAR (n=72/group), based on preoperative, POD 1, and POD 7 CARs. The relapse-free survival (RFS) and overall survival (OS) were compared between groups using propensity score matching.
Results
The high CAR group had a significantly worse RFS (P<0.001) and OS (P=0.002) at POD 7 than those in the low CAR group. However, in preoperative and POD 1 analysis, no differences were observed.
Conclusion
In patients with CRC, CAR of POD 7 was a significant prognostic factor.

Abstract PDF: Purpose
Transanal endoscopic microsurgery (TEM) is the most standardized method for the local excision of rectal neoplasms. Unfortunately, local excisions of rectal lesions by means of TEM are not completely free from undesirable functional sequela. This study was performed to evaluate the risk factors of major loss of function after TEM.
Methods
Eighty-nine patients underwent TEM between 2019 and 2020. Anorectal manometry was performed before the surgery and 3, 6, and 12 months after the surgery. The quality of life (QoL) was assessed using the Fecal Incontinence Quality of Life scale.
Results
The major decrease in QoL was observed in women in 3 months after the surgery in terms of lifestyle and frustration domains (3.6 and 3.64 points, respectively). In 3 months after the surgery, there was a significant decrease in resting pressure both in male and female patients (P=0.01). This difference remained significant 6 months after the surgery (P=0.01). In 12 months after the surgery, resting pressure returned to the preoperative level in most patients (P=0.50). A significant decrease in manometric parameters appeared when the surgery time is more than 55 minutes (P=0.05), the tumor localization is lower than 3 cm from the anus (P=0.03), and the tumor size is over 3 cm (P=0.001).
Conclusion
The most significant risk factors for the development of functional disorders after TEM are surgery time of >55 minutes, tumor localization at <3 cm from the anal verge, and tumor size of >3 cm.

Abstract PDF: Purpose
Transanal total mesorectal excision (TaTME) has been proposed to overcome surgical difficulties encountered during rectal resection, especially for patients having high body mass index or low rectal cancer. The aim of this study was to evaluate oncologic outcomes following TaTME.
Methods
This retrospective study included all consecutive patients with rectal cancer who had a TaTME from 2013 to 2019. The main outcome was the incidence of locoregional recurrence by the end of the follow-up period.
Results
Among a total of 81 patients, 96.3% were male, and their mean age was 63±9 years. The mean body mass index was 30.3±5.7 kg/m2, and the median distance from tumor to anal verge was 5.0 cm (interquartile range [IQR], 4.0–6.0 cm). Most patients had a low anterior resection performed (n=80, 98.8%) with a diverting ileostomy (n=64, 79.0%). Distal and circumferential resection margins were positive in 2.5% and 6.2% of patients, respectively. Total mesorectal excision was complete or near complete in 95.1% of patients. A successful resection was achieved in 72 patients (88.9%). After a median follow-up of 27.5 months (IQR, 16.7–48.1 months), 4 patients (4.9%) experienced locoregional recurrence. Anastomotic leaks were observed in 21 patients (25.9%). At the end of the follow-up, 69 patients (85.2%) were stoma-free.
Conclusion
TaTME was associated with acceptable oncological outcomes, including low locoregional recurrence rates in selected patients with low rectal cancer. Although associated with a high incidence of postoperative morbidities, the use of TaTME enabled a high rate of successful sphincter-saving procedures in selected patients who posed a technical challenge.

Abstract PDF

Purpose
Obesity has been known to contribute to technical difficulties in surgery. Until now, body mass index (BMI) has been used to measure obesity. However, there are reports that BMI does not always correspond to the visceral fat. Recently, bioelectrical impedance analysis (BIA) has been used for body composition analysis. This study aimed to evaluate the usefulness of the body composition index obtained using a BIA device in predicting short-term postoperative outcomes.
Methods
Data of patients who underwent elective major colorectal surgery using minimally invasive techniques were reviewed retrospectively. Body composition status was recorded using a commercial BIA device the day before surgery. The relationship between BMI, body composition index, and short-term postoperative outcomes, including operative time, was analyzed.
Results
Sixty-six patients were enrolled in this study. In the correlation analysis, positive correlation was observed between BMI and body composition index. BMI and body composition index were not associated with short-term postoperative outcomes. Percent body fat (odds ratio, 4.226; 95% confidence interval [CI], 1.064–16.780; P=0.041) was found to be a statistically significant factor of prolonged operative time in the multivariate analysis. Correlation analysis showed that body fat mass was related to prolonged operative time (correlation coefficients, 0.245; P=0.048). In the area under curve analysis, body fat mass showed a statistically significant predictive probability for prolonged operative time (body fat mass: area, 0.662; 95% CI, 0.531–0.764; P=0.024).
Conclusion
The body composition index can be used as a predictive marker for prolonged operative time. Further studies are needed to determine its usefulness.

Abstract PDF

Purpose
Hemorrhoids are the most common benign anorectal diseases. Mucopexy strengthens the anal canal mucosa, which can be performed alone or in combination with Doppler-guided hemorrhoidal artery ligation (DG-HAL). In this study, we compared the postoperative complications between simple mucopexy plus HAL with and without a Doppler guide.
Methods
This study was performed as a single-blinded randomized clinical trial. Patients referred to a tertiary colorectal referral clinic with grades 3 and 4 hemorrhoids who were candidates for surgical intervention entered the study. Thirty-six patients were randomly divided into 2 groups. Group A including 18 patients underwent mucopexy and DG-HAL and the other 18 patients (group B) underwent standard mucopexy and HAL without a Doppler guide. Postoperative pain score and the duration of oral analgesic consumption were recorded. Additionally, postoperative symptoms and complications were recorded and compared between the 2 methods.
Results
There was no significant difference between the 2 groups in terms of pain score and the duration of postoperative analgesic consumption as well as the incidence of postoperative complications. Besides, the primary grade of hemorrhoids was not significantly associated with recurrence, but there was a significant association between body mass index and Wexner score (WS) with recurrence. The mean WS of patients showed a significant decrease in both groups postoperatively. However, the rate of WS reduction was not remarkably different between the 2 groups.
Conclusion
Simple mucopexy with blind HAL (without Doppler guide) might be considered for the treatment of grades 3 and 4 hemorrhoids effectively.

Abstract PDF: An appendicovesical fistula is defined as an abnormal communication between the appendix and the urinary bladder, with only a few cases reported in the literature. It is very challenging to make an early diagnosis, due to the inability of conventional imaging modalities to detect this unique pathology. The symptoms are often mild, and there are not any specific signs or symptoms that might suggest this type of anomalous communication. We report a case of a 27-year-old male patient who presented difficulty for initiating urination, dysuria, and persistent urinary tract infections. An abdominal x-ray showed a large calculus inside the bladder. A cystoscopy was performed, where the tip of the appendix was seen protruding inside the bladder with a large fecalith adhered to the bladder wall. An appendectomy and partial cystectomy with primary repair were auspiciously achieved. A review of the literature is also presented.

Abstract PDF: Colouterine fistula is a rare disease that is primarily treated using surgical approaches. Although invasive surgery is controversial in terms of techniques and results, minimally invasive endoscopic treatments have not been widely described. However, because it is rare for these fistulas to close spontaneously, surgical treatment is often mandatory. Appropriate management of colouterine fistula is complicated, especially when the patient refuses surgery. In this case study, we provide the first description of a minimally invasive endoscopic treatment of an iatrogenic colouterine fistula using a self-expandable metallic stent after an over-the-scope clip malposition.
