    Abstract Background: Trans-anal total mesorectal excision (Ta-TME) is a novel approach for the resection of rectal cancer. Low anterior resection syndrome (LARS) is a frequent functional disorder that might follow restorative proctectomy. Data regarding bowel function after Ta-TME are scarce. The aim of this study was to evaluate the incidence and risk factors for the development of LARS following Ta-TME.
    Methods: A prospectively maintained database of all patients who underwent Ta-TME for rectal cancer at our institution was reviewed. All patients who were operated on from January 2018 to December 2021 were evaluated. The LARS score questionnaire was used via telephone interviews. Incidence, severity and risk factors for LARS were evaluated.
    Results: Eighty-five patients underwent Ta-TME for rectal cancer between January 2018 and December 2021. Thirty-five patients were excluded due to ostomy status, death, local disease recurrence, ileal pouch or lack of compliance. Fifty patients were included in the analysis. LARS was diagnosed in 76% of patients. Anastomosis distance from dentate line was identified as a risk factor for LARS via multivariate analysis (
    Conclusion: LARS is a frequent condition following ta-TME, as it is used for other approaches to low anterior resection. Anastomosis distance from dentate line is an independent risk factor for LARS. In this study neo-adjuvant therapy, hand sewn anastomosis and anastomotic leak did not increase the risk of LARS. Further studies with longer follow-up times are required to better understand the functional outcomes following Ta-TME.

    Abstract Background: Low anterior resection syndrome (LARS) is a post-proctectomy consequence characterized by variable and unpredictable bowel function, including clustering, urgency, and incontinence, which significantly impacts the quality of life. Currently, there is no established gold-standard therapy for LARS.
    Primary study objective: This study aimed to evaluate the effectiveness of the Paula method of exercise as part of an integrative treatment approach for patients with LARS.
    Design: This preliminary study utilized a single-arm pretest-posttest design.
    Setting: The study was conducted at a tertiary care medical center.
    Participants: Five patients diagnosed with LARS completed the study.
    Intervention: Participants underwent twelve weeks of individualized Paula method exercise sessions. Two questionnaires were employed to assess the severity of LARS and quality of life.
    Primary outcome measures: (1) Low Anterior Resection Syndrome (LARS) Score; (2) Memorial Sloan Kettering Cancer Bowel Function Instrument (MSK-BFI); (3) Global Quality-of-Life (QOLS) Score ‎.
    Results: All participants completing the 12-week Paula exercise regimen reported no difficulty in engaging with the exercises. Statistically significant improvements were observed in both the LARS score and MSK-BFI (P = .039 and P = .043, respectively, Wilcoxon Rank Sum test). While there were improvements in the global quality-of-life score and functional scales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, these improvements did not reach statistical significance.
    Conclusions: This preliminary study suggests that patients with LARS can successfully complete a 12-week exercise program using the Paula method, resulting in improved LARS scores. However, further investigation through larger, multicenter, randomized controlled trials is necessary to establish the efficacy of these exercises as a treatment for LARS.

    Abstract Purpose: Up to 20% of patients suffering from symptomatic hemorrhoids will require surgery. Excisional hemorrhoidectomy (EH) and stapled hemorrhoidopexy (SH) are both standard and safe procedures. While SH has a short-term advantage of faster recovery and lower postoperative pain, its long-term efficacy is debatable. This study aims to compare the outcomes of EH, SH, and a combined procedure of both.
    Methods: A retrospective study compared the outcomes of patients treated surgically for hemorrhoids over a 5-year period. Eligible patients were asked by phone to complete a questionnaire evaluating recurrent symptoms, fecal incontinence, satisfaction, and self-assessed improvement in quality of life (QOL).
    Results: This study included 362 patients, of whom 215 underwent SH, 99 underwent EH, and 48 underwent a combined procedure. No statistically significant differences were found between groups regarding complications, symptoms recurrence, or fecal incontinence. Combined procedure patients had significantly higher self-assessed improvement in QOL (P=0.04).
    Conclusion: In patients with symptomatic hemorrhoids, a tailored approach to symptomatic hemorrhoids is associated with high satisfaction rates and self-assessed improvement in QOL.

    Abstract BACKGROUND Behcet's disease (BD) is defined as vasculitis involving arteries and veins of any size and affecting almost any organ system. Abdominal manifestations of BD are diverse and nonspecific. Mucosal ulcerations can be seen in the gastrointestinal tract. Extensive ulcerations, especially ileocecal lesions, can lead to perforation, strictures, fistulas, and abscesses. Pneumatosis cystoides intestinale is a rare benign condition characterized by multiple submucosal or subserosal, gas-filled cysts in the gastrointestinal tract wall. Pneumatosis cystoides coli (PCC) affects the colon, can present with a wide range of manifestations, and can mimic many different systemic diseases. We describe a case of PCC in a patient with Behcet's disease who presented to the Emergency Department with a clinical suspicion of acute abdomen. CASE REPORT A 40-year-old man with complicated Behcet's disease, treated with high-dose steroids, presented with acute abdomen and CT scan findings highly suggestive of intestinal obstruction due to ileocolic intussusception. He underwent laparoscopic right hemicolectomy. Pathology demonstrated PCC disease. CONCLUSIONS Pneumatosis cystoides coli can present with a broad range of symptoms and can be secondary to many systemic and autoimmune diseases. With radiological evidence and a high level of suspicion, unnecessary surgery can be prevented.

    Abstract A polyp is defined as any mass protruding into the lumen of a hollow viscus. Colorectal polyps may be classified by their macroscopic appearance as sessile (flat, arising directly from the mucosal layer) or pedunculated (extending from the mucosa through a fibrovascular stalk). Colorectal polyps may also be histologically classified as neoplastic or as non-neoplastic (hyperplastic, hamartomatous, or inflammatory). The neoplastic polyps are of primary importance because they harbor a malignant potential, which represents a stage in the development of colorectal cancer. For this reason, it is essential to identify these polyps at a sufficiently early stage, when a simple outpatient procedure to remove them can interrupt the development of colorectal cancer and prevent disease and death. When invasive carcinoma arises in a polyp, careful consideration must be given to ensuring the adequacy of treatment. Although most neoplastic polyps do not evolve into cancer, it is well accepted that the majority of colorectal carcinomas evolve from adenomatous polyps; the sequence of events leading to this transformation is referred to as the adenoma-to-carcinoma sequence. The presence of a systemic process that promotes the development of multiple gastro-intestinal polyps is termed 'polyposis'. Hereditary gastro-intestinal polyposis syndromes account for approximately 1% of all cases of colorectal cancer and are associated with a broad spectrum of extra-colonic tumors. Early detection and accurate classification of these syndromes are essential, in order to initiate a surveillance program for the early detection of cancer. Several polyposis syndromes have been described, each having its own genetic basis and characteristic polyp distribution, clinical presentation, and malignancy risk. Diagnostic modalities and treatment options for neoplastic polyps-as well as the most prevalent polyposis syndromes-are reviewed below.

    Abstract Surgery for rectal cancer in complex and entails many challenges. While the laparoscopic approach in general and specific to colon cancer has been long proven to have short term benefits and to be oncologically safe, it is still a debatable topic for rectal cancer. The attempt to benefit rectal cancer patients with the known advantages of the laparoscopic approach while not compromising their oncologic outcome has led to the conduction of many studies during the past decade. Herein we describe our technique for laparoscopic proctectomy and assess the current literature dealing with short term outcomes, immediate oncologic measures (such as lymph node yield and specimen quality) and long term oncologic outcomes of laparoscopic rectal cancer surgery. We also briefly evaluate the evolving issues of robotic assisted rectal cancer surgery and the current innovations and trends in the minimally invasive approach to rectal cancer surgery.

    Abstract Background: Colorectal cancer is a condition which is associated with substantial morbidity and mortality. The aim of this study was to assess urinary dysfunction and its effect on quality of life in women who underwent total mesorectal excision compared to women treated by partial mesorectal excision for treatment of rectal cancer.
    Methods: We performed a retrospective cohort study at a tertiary university hospital between January 2014 and December 2019. A comparison was performed between women who underwent total mesorectal excision as opposed to partial mesorectal excision for treatment of rectal cancer. Pre-operative, intra-operative and post-operative data were compared between groups. Data regarding radiation therapy was recorded and compared as well. Urinary dysfunction and its impact on quality of life were assessed using UDI-6 and USIQ questionnaires. Further univariate and multivariate analyses were performed in the attempt of assessing risk factors for urinary dysfunction.
    Results: A total of 107 women were included in the study, 73 women underwent partial mesorectal excision as opposed to 34 women who were treated by total mesorectal excision. Twenty-five women in the TME group underwent radiation therapy prior to surgery as opposed to none in the PME group (p < 0.001). Urinary dysfunction following surgery as assessed using the UDI-6 questionnaire did not differ between groups. Similar findings were recorded with regard to the impact of urinary dysfunction on quality of life as assessed using the USIQ questionnaire. Following multivariate analysis longer hospital stay was associated with increased risk of some degree of urinary dysfunction.
    Conclusions: Women undergoing total mesorectal excision have comparable results to partial mesorectal excision with regard to urinary dysfunction.

    Abstract Objectives: To assess the potential role of low monoenergetic images in the evaluation of acute appendicitis.
    Methods: A retrospective study of 42 patients with pathology proven acute appendicitis underwent contrast-enhanced-CT conducted on a single-source-DECT before surgery. Attenuation, SNR, and CNR were calculated on both monoenergetic and conventional images and compared to 24 abdominal CT-scans with normal appendix. Representative conventional and monoenergetic images were randomized and presented side-by-side to three abdominal radiologists to determine preferred images for detecting inflammation. Additionally, six individual acute inflammatory characteristics were graded on a 1-5 scale to determine factors contributing to differences between conventional and monoenergetic images by 2 abdominal radiologists. Paired t-tests, Wilcoxon and McNemar tests, and intra-observer error statistics were performed.
    Results: For the inflamed appendixes monoenergetic images had overall increased attenuation (average ratio 1.7; P < 0.05), signal-to-noise-ratio (6.7 ± 3.1 vs 4.2 ± 1.6; P < 0.001) and contrast-to-noise-ratio (12.1 ± 3 vs 9 ± 2.1; P < 0.001). Moreover, this increase was not found in normal appendixes (P < 0.001 vs p = 0.28-0.44). Subjectively, radiologists showed significant preferences towards monoenergetic images (P < 0.001), with inter-reader agreement of 0.84. Two parameters, diffuse bowel wall and mucosal enhancement, received significantly higher scores on monoenergetic images (average 4.3 vs. 3.0; P < 0.001 and 2.8 vs. 2.3 P < 0.03 respectively, with interobserver agreements of 62% and 52%).
    Conclusion: Increased bowel wall conspicuity from enhanced attenuation, SNR, and CNR on low monenergetic CT images results in a significant preference by radiologists for these images when assessing acute inflamed appendixes. Thus, close inspection of low monoenergetic images may improve the visualization of acute inflammatory bowel processes.
