Laparoscopic surgery has become a frequently used modality for rectal tumour surgery. A fistula between the rectum and lower urinary tract is one of the possible complications, with rectovesical fistulas occurring most frequently. This case report presents a 66-year-old man who underwent a laparoscopic low-anterior resection of the rectum due to the presence of a polyp with a high risk of malignant transformation. At the time of discharge on the eleventh postoperative day, the patient returned to the hospital with a fever, scrotal swelling and pain in the right hemiscrotum. These symptoms began four hours after discharge from the hospital. There was no sign of faecaluria. The presence of gas in the urinary bladder was confirmed after catheter insertion. The patient was diagnosed with a fistula between the anterior wall of the rectum and seminal vesicles. The diagnosis was based on cystoscopy findings, X-ray and computed tomography irrigography. The condition was treated conservatively by suprapubic insertion of a catheter and antibiotics. The total length of the treatment, including management of subsequent complications, was 4 months. Twelve months after the complication developed, the patient is symptom free, without urinary tract infection recurrence, and is under the care of both surgery and urology clinics. We describe the clinical symptoms, possibilities of treatment and the result of treatment of this rare complication of rectum low-anterior resection, which has never been described in the literature before.

BACKGROUND: Low anterior resection syndrome (LARS) covers disordered bowel function after rectal resection, leading to deterioration in patients' quality of life. The aim of this study was to evaluate anorectal function after laparoscopic low anterior resection (LAR) by means of standardized instruments. METHODS: This was a prospective clinical cohort study conducted in a single institution to assess functional outcome of patients 1 year after laparoscopic LAR by means of LARS score and high-resolution anorectal manometry. RESULTS: In total, 65 patients were enrolled in the study. Mean tumour height was 9.4 ± 1.8 cm; total mesorectal excision during laparoscopic LAR with low end-to-end colorectal anastomosis was performed in all patients. One year after the surgery, minor LARS was detected in 33.9% of patients, major LARS in 36.9% of patients. Anorectal manometry revealed decreased resting pressure and normal squeeze pressure of the anal sphincters in the majority of our patients. Rectal compliance and rectal volume tolerability (first sensation, urge to defaecate and discomfort volume) were significantly reduced. The statistical testing of the correlation between LARS and manometry parameters showed that with increasing seriousness of LARS, values of some parameters (resting pressure, first sensation, urge to defaecate, discomfort volume and rectal compliance) were reduced. CONCLUSION: This study indicates that the majority of patients after laparoscopic LAR experience symptoms of minor or major LARS. These patients have decreased resting anal sphincter pressures, decreased rectal volume tolerability and decreased rectal compliance.

BACKGROUND AND OBJECTIVES: The aim was to evaluate the impact of radiotherapy (RT) on anorectal function of patients with low rectal cancer undergoing low anterior resection (LAR). METHODS: Prospective clinical cohort study conducted to assess the functional outcome by means of high-resolution anorectal manometry and LARS score. RESULTS: In total, 65 patients were enrolled in the study (27 patients underwent LAR without RT, 38 patients underwent RT and LAR). There were no statistically significant differences between study subgroups regarding demographic and clinical data; postoperative morbidity was significantly higher in irradiated patients. One year after the surgery, mean LARS score was significantly higher in patients who underwent RT and surgery. Major LARS was detected in 37.0% of irradiated patients and in 14.8% of patients after surgery alone. Anorectal manometry revealed significantly lower resting pressures in patients after RT and LAR; the squeeze pressures were similar. Rectal compliance and all volumes describing rectal sensitivity (first sensation, urge to defecate, and discomfort volume) were significantly lower in irradiated patients. CONCLUSIONS: RT significantly deteriorates the functional outcome of patients after LAR. Manometry revealed internal sphincter dysfunction, reduced capacity, and compliance of neorectum, which seem to have a significant correlation with LARS presence/seriousness.

INTRODUCTION: Over the last decades outcomes for rectal cancer surgery have improved with increasing survival and lower recurrence rates. Nevertheless, functional disorders are still frequent. Low anterior resection with total mesorectal excision (TME) in patients with rectal cancer has improved oncological outcomes. However, most of them will have significant changes in quality of life, including varying degree of bowel dysfunction. Aim of this study was to analyse prevalence of LARS (low anterior resection syndrome) in patients with rectal cancer after miniinvasive restorative resection and to define its risk factors. METHODS: Between March 2016 and June 2018, patients who underwent elective miniinvasive (laparoscopic or robotic) rectal resection were enrolled. Bowel dysfunction was evaluated by LARS questionnaire and filled out 6, 12, and 24 months after primary operation or after ileostomy closure. 98 patients completed the questionnaires - 58 laparoscopic operations, 34 robotic and 6 open procedures. 69 patients underwent TME, tumor-specific mesorectal excision 21 patients. 8 patients underwent transanal TME. The clinical characteristics, surgical perioperative and postoperative outcomes did not differ between these groups. Only, significantly more patients underwent neoadjuvant radiotherapy in the robotic group (p=0.004). RESULTS: 59.8% patients reported major LARS 6 months after surgery and 29.7% after 24 months. Protentional risk factors are age (p.

BACKGROUND: Benchmark comparisons in surgery allow identification of gaps in the quality of care provided. The aim of this study was to determine quality thresholds for high (HAR) and low (LAR) anterior resections in colorectal cancer surgery by applying the concept of benchmarking. METHODS: This 5-year multinational retrospective study included patients who underwent anterior resection for cancer in 19 high-volume centres on five continents. Benchmarks were defined for 11 relevant postoperative variables at discharge, 3 months, and 6 months (for LAR). Benchmarks were calculated for two separate cohorts: patients without (ideal) and those with (non-ideal) outcome-relevant co-morbidities. Benchmark cut-offs were defined as the 75th percentile of each centre's median value. RESULTS: A total of 3903 patients who underwent HAR and 3726 who had LAR for cancer were analysed. After 3 months' follow-up, the mortality benchmark in HAR for ideal and non-ideal patients was 0.0 versus 3.0 per cent, and in LAR it was 0.0 versus 2.2 per cent. Benchmark results for anastomotic leakage were 5.0 versus 6.9 per cent for HAR, and 13.6 versus 11.8 per cent for LAR. The overall morbidity benchmark in HAR was a Comprehensive Complication Index (CCI®) score of 8.6 versus 14.7, and that for LAR was CCI® score 11.9 versus 18.3. CONCLUSION: Regular comparison of individual-surgeon or -unit outcome data against benchmark thresholds may identify gaps in care quality that can improve patient outcome.

UNLABELLED: The most important quality parameters of rectal cancer surgery are oncological radicality, postoperative complications, recurrence rate and survival. Rectal dysfunction following low anterior resection occurs in up to 25-50% of patients. Despite its high frequency, however, it does not receive enough attention. Rectal dysfunction after surgery includes frequent bowel movements, urgency, incomplete evacuation, incontinence or sexual and urinary dysfunctions. The complex of symptoms is collectively referred to as the low anterior resection syndrome - LARS. In this review, we discuss the alterations in anorectal physiology after low anterior resection, the etiology and risk factors of LARS, different types of neorectal reservoir construction, and various options for prevention and treatment of LARS. Furthermore, sexual and urinary dysfunction is briefly reviewed. KEYWORDS: low anterior resection bowel dysfunction incontinence anorectal physiology.

INTRODUCTION: Over the last decades outcomes for rectal cancer surgery have improved, with increasing survival rates. Nevertheless, functional disorders are still frequent. AIM: To evaluate sexual and urinary outcomes of miniinvasive total mesorectal excision (TME). MATERIAL AND METHODS: Between March 2016 and June 2018 patients with rectal cancer who underwent miniinvasive TME with a sphincter-saving procedure were enrolled. The questionnaires were completed before therapy, and 6, 12, and 24 months after stoma closure. We used the Female Sexual Function Index (FSFI), the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function questionnaire (IIEF). RESULTS: Ninety-eight patients completed the questionnaires. Only patients who underwent laparoscopic (39) or robotic TME (27) were enrolled. The characteristics and surgical outcomes did not differ significantly between these groups. The IPSS between the groups was comparable before and after the operation with no significant difference, increased at 6 months and then decreased consecutively. In comparison with baseline, IPSS was significantly lower in the laparoscopic and robotic groups at 6 months and was comparable to baseline at 24 months in both groups. Oppositely, the IIEF was significantly lower at 6 months after ileostomy closure in the robotic group (p < 0.05), but not in the laparoscopic group (p = 0.59) and both returned to baseline at 24 months. FSFI was significantly lower in the laparoscopic group (p = 0.017) 6 months after surgery and returned to baseline at 24 months in both groups. CONCLUSIONS: Laparoscopic and robotic TME showed similar functional results 2 years after stoma resection.

INTRODUCTION: Anastomotic leak after colorectal surgery is a major problem associated with higher morbidity and mortality. In most cases of contained leaks, treatment recommendations are clear and effective. However, in rare cases like necrotizing pelvic infection, there is no clear treatment of choice, despite the mortality rate almost 21%. We present successful management with endoscopic vacuum-assisted closure therapy. THE PRESENTATION OF A CASE: A 68-year-old female patient with BMI 26, hypothyroidism and high blood pressure was indicated to low anterior rectal resection because of high-risk neoplasia of lateral spreading tumor type of the upper rectum. Four days after the primary operation, sepsis (SOFA 12) with diffuse peritonitis and unconfirmed leak according to CT led to surgical revision with loop ileostomy. On postoperative days 6-10, swelling, inflammation and subsequent necrosis of the right groin and femoral region communicating with the leak cavity developed. The endoscopy confirmed a leak of 30% of the anastomotic circumference with the indication of debridement and endoscopic vacuum-assisted closure therapy. EVAC sessions with 3-4 day intervals healed the leak cavity. Secondary healing of the skin defects required 4 months. CONCLUSION: Necrotizing pelvic infection after a leak of the colorectal anastomosis is a very rare complication with high morbidity and mortality. Endoscopic vacuum-assisted closure therapy should be implemented in the multimodal therapeutic strategy in case of major leaks, affecting up to 270° of the anastomotic circumference.

INTRODUCTION: Fluid therapy is a fundamental component of surgical care. Recent data regarding fluid restriction has shown an association with improved outcomes. The aim of this study is to determine whether the use of restrictive approaches in perioperative fluid administration improves patient outcomes following low anterior resection. MATERIAL AND METHODS: 89 patients undergoing low anterior resection included in this study were divided by the median 14.9 mL/kg/h into group A (7.4-14.7 mL/kg/h) and group B (14.9-36.8 mL/kg/h) within intraoperative fluid administration, and by the median 3.3 mL/kg/h into group C (2.0-3.3 mL/kg/h) and group D (3.3-6.9 mL/kg/h) for fluid administration on the day of surgery. The main outcomes measured were cardiac and pulmonary complications, the incidence of anastomotic leak and wound infections, gastrointestinal function recovery, laboratory inflammatory markers and the length of hospital stay. RESULTS: The restricted perioperative fluid regimen significantly reduced the risk of pleural effusion and anastomotic leak in patients after low anterior resection. The overall incidence of anastomotic leak was 9.0%. Another significant risk factor for anastomotic leak was neoadjuvant radiochemotherapy (15.9% vs. 2.2%, p=0.03). CONCLUSION: The restricted perioperative fluid regimen reduces postoperative morbidity in patients after low anterior resection. Hospital stay remains unchanged.

BACKGROUND: One of the prerequisites for proper healing of the anastomosis after a colorectal resection is adequate blood supply to the connected intestinal segments. It has been proposed that adequate visualization of the blood flow using indocyanine green (ICG) could lead to the reduction in the incidence of anastomotic leakage (AL). The aim of this study was to assess the effectiveness of intraoperative fluorescence angiography (FA) in decreasing the incidence of AL after minimally invasive low anterior resection (LAR) with total mesorectal excision (TME) in rectal cancer patients and to determine predictors of anastomotic leak. METHODS: From August 2015 to January 2019, data from 100 patients who underwent mini-invasive TME for rectal cancer using FA with indocyanine green (ICG) were prospectively collected and analyzed. They were compared with retrospectively analyzed data from a historical control group operated by one team of surgeons before the introduction of FA from November 2012 to August 2015 (100 patients). All patients from both groups were operated sequentially in one oncological center in Nový Jičín. RESULTS: The incidence of AL was significantly lower in the ICG group (19% vs. 9%, p = 0.042, χ2 test). In fifteen patients in the ICG group (15%), the resection line was moved due to insufficient perfusion. Using Pearson's χ2 test, diabetes (p = 0.036) and application of a transanal drain (NoCoil) (p = 0.032) were identified as other risk factors (RFs) for AL. CONCLUSION: The use of ICG to visualize tissue perfusion in low rectal resections for cancer can lead to a reduction of AL.
