Chemoradiation, Consolidation Chemotherapy, and Watch and Wait for Early Rectal Cancer.

As watch and wait has become an attractive management alternative among patients with rectal cancer who achieve a clinical complete response to neoadjuvant chemoradiation, the focus of organ preservation has now shifted toward the use of this approach in patients with early rectal cancer. These patients would otherwise be treated without the use of neoadjuvant therapy for oncological reasons. The sole purpose of any neoadjuvant treatment here would be the achievement of a complete clinical response in an attempt to avoid total mesorectal excision. This has become particularly interesting after the incorporation of total neoadjuvant therapy regimens. These regimens have resulted in significantly higher rates of complete tumor regression and therefore become an interesting alternative among early rectal cancer patients where organ preservation is desired. The present review provides an overview of the currently available evidence and the preliminary experience with this rather controversial approach.

FiLaC® procedure for highly selected anal fistula patients: indications, safety and efficacy from an observational study at a tertiary referral center.

BACKGROUND: the ideal clinical profile of patients or fistula features for fistula laser closure (FiLaC®) technique remain to be established. The aim of this study was to analyze clinical outcomes and the safety profile of FiLaC® in search for an ideal setting for this technique. METHODS: a retrospective observational study was performed from a prospective database including all consecutive patients who underwent surgery for anal fistula (AF) with FiLaC® in the coloproctology unit of a tertiary referral center, between October 2015 and December 2021. The FiLaC® procedure was offered to AF patients who were considered to be at risk of fecal incontinence. Fistulas were described according to Parks' classification and categorized as complex or simple according to the American Gastroenterological Association (AGA) guidelines. Healing was defined by the closure of the internal and external openings for at least six months. Predictive factors of AF healing were investigated. RESULTS: a total of 36 patients were included, with a mean age of 48 ± 13.9 years. Twenty patients (55.6 %) were male and 13 patients (36 %) had Crohn's disease (CD). Fourteen patients (38.8 %) had a complex fistula. The primary and secondary healing rates were 55.6 % and 91.7 %, respectively, during a median follow-up time of 12 months (IQR 7-29). No fecal continence impairment was registered in any case. The proportion of patients with primary healing was significantly higher in CD patients (76.9 % vs 43.5 %, p = 0.048). CONCLUSIONS: FiLaC® is a sphincter-preserving procedure with an excellent safety profile and reasonable success rate despite of the strict patient selection. This technique may be attractive for patients with CD due to its higher primary healing rate.

Traumatic deficient perineum: surgical management and outcome from a single center.

INTRODUCTION AND HYPOTHESIS: Deficient perineum is a disruption of the perineal body and distal rectovaginal septum presenting with anal incontinence and a range of urogenital symptoms. There is scarce reported outcome of this condition with management often delayed and with a variety of surgical alternatives. This study aims to determine faecal continence outcomes after long-term surgical repair. METHODS: Patients were included for analysis after surgical repair between 1989 and 2012. Cases were preoperatively assessed by endosonography and anorectal manometry with a record of their continence with the Cleveland Clinic Incontinence Score (CCIS). Surgical repair comprised an overlapping repair of the external anal sphincter (EAS) with levatorplasty. There was selective use of internal anal sphincter (IAS) suture and/or advancement perineoplasty for soft tissue reconstruction. Patients were clinically evaluated for functional outcomes with comparison of their postoperative CCIS. RESULTS: There were 20 patients (median age 55.5 years; range 29-81 years) with a median duration of incontinence symptoms of 174 (range 1-540) months. All patients had an EAS and IAS defect with 14 (70%) undergoing an IAS suture and 10 (50%) a Corman-style anoplasty. Over a median follow-up of 137.2 (range 13-322) months, there was a significant decrease in the recorded median preoperative vs. postoperative CCIS 18, range 13-20 vs. 2, range 0-10, respectively; p < 0.001) with 18 (90%) satisfied with the functional outcome. Faecal diversion was not used in any of the patients. CONCLUSIONS: Experienced delayed repair of a traumatic cloaca is associated with an acceptable functional outcome at medium- to long-term follow-up.

Patients' Perceived Satisfaction Through Telephone-Assisted Tele-Consultation During the SARS-CoV-2 Pandemic Period: Observational Single-Centre Study at a Tertiary-Referral Colorectal Surgery Department.

Introduction: The pandemic produced by SARS-CoV-2 has obliged us to set up the tele-assistance to offer a continuity of care. This implies an innovation, being the degree of satisfaction of patients unknown. Methods: A telephonic survey was conducted with the validated in the Spanish tool Telehealth Usability Questionnaire (Telehealth Usability Questionnaire; rating from 1-7) of all candidate patients assisted consecutively in the Coloproctology Unit. We included demographic variables, education level, job status, diagnosis and consultation type. A descriptive study was done. The relationship between the willingness of consultation model in the future (telemedicine vs traditional) and the categorical variables was analysed through the chi-squared test. Results: A total of 115 patients were included. The average age was 59.9 years, being 60% women. The average score in each of the survey items was higher than 6 in all the questions but 1. 26.1% of the surveyed patients confessed being advocated to tele-assistance in the future. The only factors related to greater willingness to tele-assistance were male gender (37% vs 18.8%; P = .03) and a higher academic preparation level in favour of higher technical studies (35.9%) and university studies (32.4%) opposite to the rest (P = .043). The rest of variables studied, job status, labour regimen, diagnostic group and consultation type did not show any relationship. Conclusions: A vast majority of patients answered favourably to almost all the items of the survey. However, only 26.1% of them would choose a model of tele-assistance without restrictions.

Adult Intestinal Intussusception: Practical Issues and Concerns.

CASE SUMMARY: A 37-year-old woman with no relevant past medical history presented to the emergency department after a 2-day-long period of crampy abdominal pain with an inability for oral intake because of persistent vomiting. The physical examination was unremarkable. Abdominal CT scan with water-soluble oral contrast revealed an ileocecal intussusception (Fig. 1). Because the patient was hemodynamically stable and no abdominal tenderness was found, a delayed surgical intervention was planned with laparoscopic approach. During intervention, the intestinal invagination was reduced, a cecal neoplasm suspected, and a right hemicolectomy with complete mesocolic excision was performed (Fig. 2). Postoperative recovery was uneventful, with discharge on postoperative day 5. The definite pathological report showed well-differentiated colon adenocarcinoma pT2N1aMx, with 1 of 49 positive lymph nodes.

Interval colonoscopy following acute diverticulitis should not be discouraged yet: results from a retrospective cohort.

BACKGROUND: Although included in some guidelines, the recommendation of interval colonoscopy after an acute diverticulitis (AD) episode has recently been questioned. In this study, we evaluated the incidence of colon cancer during the follow-up of an episode of AD. METHODS: A retrospective review was carried out of patients with conservatively treated AD at our Institution (January 2011 to December 2018) with or without endoscopic study. Patients who had no colonoscopy performed were followed for two years. The demographic, clinical, radiological, follow-up and anatomopathological records were analysed. We determined CT scan validity for the differential diagnosis of CC and AD; sensibility, specificity, predictive values and likelihood ratios were calculated. Patients lost to follow-up and patients who had had colonoscopy in the previous three years were excluded. RESULTS: This study included 285 patients with a mean age of 59 years. A total of 225 interval colonoscopies were performed and 60 patients without colonoscopy were followed up. There were 19 CC (6.7%) diagnosed, 14 with interval colonoscopy and 5 during follow-up; 8 (42.1%) happened in patients who had had an episode of uncomplicated AD. Although CT scan accuracy is high, 87.7%, positive and negative likelihood ratios were low, 4.67 and 0.64, respectively. CONCLUSIONS: Interval colonoscopy should still be advisable after an episode of AD. The rationale for this statement is based on a non-negligible rate of hidden CC and an important uncertainty in the differential diagnosis.

Peristomal Pyoderma Gangrenosum in a Rectal Cancer Patient With an Ileostomy: A Case Study.

BACKGROUND: Peristomal pyoderma gangrenosum (PPG) is a rare complication mainly associated with inflammatory bowel disease. Although it has also been found in patients with an ileostomy with rectal cancer, the best treatment options in this context have not been precisely elucidated. CASE: This case report describes the importance of a multidisciplinary treatment approach for a rare case of PPG around a protective ileostomy resulting from rectal cancer. CONCLUSIONS: Early diagnosis of PPG is imperative to avoid further extension of the lesion. Aggressive management with a multidrug treatment, both topical and systemic, is recommended in severe cases. Close monitoring of the response is necessary, given the variability in the effectiveness of the treatments.

Contribution of intraoperative colonoscopy in a colorectal surgery unit.

OBJECTIVES: Intraoperative colonoscopy (IC) is routinely used in colorectal surgery procedures, both oncologic and benign ones. Despite its extensive use there is a lack of literature addressing this important issue. The aims of this paper are to determine the contributions of this tool, especially considering changes in attitude from preoperative designed intervention. MATERIALS AND METHODS: This study is a retrospective analysis of a prospective maintained database. Patients who underwent colorectal resection and IC during a four-year period (2009-2012). The indications for performing IC in our unit are: Incomplete preoperative colonoscopy, confirm the exact location of the tumor and polypectomy of any lesion distant from the planned resection segment. RESULTS: The success rate in performing IC is 100%, including 42% of them made trans-anastomotic. No postoperative complications that were attributable to the endoscopy were detected. Routine practice led to a change in attitude in 5% of the patients analyzed; 2% of the global sample corresponded to synchronous tumors finding. Of those patients in whom polypectomies where achieved during the procedure a 14.3% of potentially malignant lesions were resected. CONCLUSIONS: Intraoperative colonoscopy is a useful and safe tool that in view of these results should be taken into account at any colorectal surgery unit. Trans-anastomotic techniques do not raise morbidity.

Prevalence of anal incontinence in a working population within a healthcare environment.

OBJECTIVES: Anal incontinence is a devastating affliction with several considerations that make it difficult to define in terms of epidemiology with good precision. The aim of the present work is to study the prevalence of an important disorder such as anal incontinence in a healthy working population within a sanitary environment. MATERIAL AND METHODS: A cluster of easy understanding and filling inquiry forms are distributed to 910 apparently healthy individuals at our hospital. This questionnaires include filiation data, passed medical history, presence or not of Incontinence and other symptoms such as urgency. The Cleveland Clinic Incontinence Score is also registered. RESULTS: Anal incontinence is present in a 21.2% of subjects when considered in any of it forms (flatus, liquid or solid faeces). A Clevleand Clinic Incontinence Score higher than 6 was obtained in a 7.3% of the sample and higher than 10 in 1.2%. No gender predominance has been identified. A slightly higher severity is recognised with increasing age. Obstetric and anal surgical background are the only related factors identified in the studied sample. CONCLUSIONS: Faecal incontinence is a high prevalent affliction, even among apparently healthy population. Considering the aetiologic factors that have been established, prevention during obstetric and anal surgical procedures is absolutely mandatory.

Laparoscopy may decrease morbidity and length of stay after elective colon cancer resection, especially in frail patients: results from an observational real-life study.

BACKGROUND: Advantages of laparoscopic approach in colon cancer surgery have been previously demonstrated in controlled, randomized trials and in retrospective analysis of large administrative databases. Nevertheless, evidence of these advantages in prospective, observational studies from real-life settings is scarce. METHODS: This is a prospective, observational study, including a consecutive series of patients that underwent elective colonic resection for cancer in 52 Spanish hospitals. Pre-/intraoperative data, related to patient, tumor, surgical procedure, and hospital, were recorded as well as 60-day post-operative outcomes, including wound infection, complications, anastomotic leak, length of stay, and mortality. A univariate and multivariate analysis was performed to determine the influence of laparoscopy on short-term post-operative outcome. A sub-analysis of the effect of laparoscopy according to patients' pre-operative risk (ASA Score I-II vs. III-IV) was also performed. RESULTS: 2968 patients were included: 44.2% were initially operated by laparoscopy, with a 13.9% conversion rate to laparotomy. At univariate analysis, laparoscopy was associated with a decreased mortality (p = 0.015), morbidity (p < 0.0001), wound infection (p < 0.0001), and post-operative length of stay (p < 0.0001). At multivariate analysis, laparoscopy resulted as an independent protective factor for morbidity (OR 0.7; p = 0.004), wound infection (OR 0.6; p < 0.0001), and length of post-operative stay (Effect-2 days; p < 0.0001), compared to open approach. These advantages were more relevant in high-risk patients (ASA III-IV), even if the majority of them were operated by open approach (67.1%). CONCLUSIONS: In a real-life setting, laparoscopy decreases wound infection rate, post-operative complications, and length of stay, especially in ASA III-IV patients.

Squamous Cell Carcinoma of the Peristomal Skin of a Gastrostomy: Case Study.

BACKGROUND: Primary skin tumors that develop at enteral feeding stomas are extremely rare. Ongoing surveillance of these stomas, including the peristomal skin, is essential to early diagnosis and treatment of these tumors. CASE: A 73-year-old man with an esophageal chemical burn caused by swallowing sodium hypochlorite (bleach) approximately 50 years earlier that was initially managed with esophageal exclusion and placement of a gastrostomy device for enteral feeding presented with an exophytic and painful mass of the skin adjacent to his gastrostomy site. The pathologic report confirmed differentiated squamous cell skin carcinoma. CONCLUSION: Skin tumors arising from chronic wounds or ulcers of the skin surrounding a gastrostomy device are rare but should be considered if hypergranulation tissue or a peristomal lesion appears to be nonhealing. WOC nurses are frequently consulted for care of granulomas, and close monitoring is essential for avoiding this potentially fatal complication.
