Feasibility and outcomes of robotic sphincter-preserving surgery for rectal cancer after neoadjuvant treatment in patients with preexisting colostomy.

BACKGROUND: Diverting colostomy followed by neoadjuvant treatment is a treatment of choice for obstructive rectal cancer. Such patients may be treated via a robotic approach with several advantages over conventional laparoscopic surgery. Conversely, the existing stoma may interfere with the optimal trocar position and thus affect the quality of robotic surgery. Moreover, the console surgeon does not face the patient, which may endanger the stoma. METHODS: Patients with rectal cancer who underwent sphincter-preserving surgery were retrospectively investigated using a robotic platform after neoadjuvant treatment at our hospital. Based on pretreatment stoma creation, patients were divided into the NS (those without a stoma) and S groups (patients with a stoma). Baseline characteristics, types of neoadjuvant treatment, short-term surgical outcomes, postoperative anorectal manometric data, and survival were compared between the groups. RESULTS: The NS and S groups comprised 65 and 9 patients, respectively. Conversion to laparotomy was required in three patients in the NS group. The S group required a longer console time than the NS group (median: 367 vs. 253 min, respectively, p = 0.038); however, no difference was observed in the total operative time (p = 0.15) and blood loss (p = 0.70). Postoperative complication rates, anorectal function, and oncological outcomes were similar between the groups. CONCLUSIONS: Although console time was longer in patients with a stoma, robotic surgery could be performed safely like in those without a stoma after neoadjuvant treatment.

Female Anorectal Malformation with Genitourinary Prolapse: A Rare Association.

ABSTRACT: Genitourinary prolapse in newborn females as an introital mass is an uncommon entity. The usual causative mechanisms are poor pelvic innervation, damage or pressure on pelvic musculature and ligaments etc. Different methods of reduction as treatment were proposed in the past. Apart from uncommon occurrence of genitourinary prolapse in newborns, its association with anorectal malformation is not reported in English literature after searching on PubMed and Google Scholar. We report three cases of genitourinary prolapse with anorectal malformation in newborn females where decompressing colostomy was curative for the condition reflecting increased intra-abdominal pressure as causative mechanism.

A risk prediction model based on machine learning algorithm for parastomal hernia after permanent colostomy.

OBJECTIVE: To develop a machine learning-based risk prediction model for postoperative parastomal hernia (PSH) in colorectal cancer patients undergoing permanent colostomy, assisting nurses in identifying high-risk groups and devising preventive care strategies. METHODS: A case-control study was conducted on 495 colorectal cancer patients who underwent permanent colostomy at the Second Affiliated Hospital of Anhui Medical University from June 2017 to June 2023, with a 1-year follow-up period. Patients were categorized into PSH and non-PSH groups based on PSH occurrence within 1-year post-operation. Data were split into training (70%) and testing (30%) sets. Variable selection was performed using Least Absolute Shrinkage and Selection Operator (LASSO) regression, and binary classification prediction models were established using Logistic Regression (LR), Support Vector Classification (SVC), K Nearest Neighbor (KNN), Random Forest (RF), Light Gradient Boosting Machine (LGBM), and Extreme Gradient Boosting (XgBoost). The binary classification label denoted 1 for PSH occurrence and 0 for no PSH occurrence. Parameters were optimized via 5-fold cross-validation. Model performance was evaluated using Area Under Curve (AUC), specificity, sensitivity, accuracy, positive predictive value, negative predictive value, and F1-score. Clinical utility was evaluated using decision curve analysis (DCA), model explanation was enhanced using shapley additive explanation (SHAP), and model visualization was achieved using a nomogram. RESULTS: The incidence of PSH within 1 year was 29.1% (144 patients). Among the models tested, the RF model demonstrated the highest discrimination capability with an AUC of 0.888 (95% CI: 0.881-0.935), along with superior specificity, accuracy, sensitivity, and F1 score. It also showed the highest clinical net benefit on the DCA curve. SHAP analysis identified the top 10 influential variables associated with PSH risk: body mass index (BMI), operation duration, history and status of chronic obstructive pulmonary disease (COPD), prealbumin, tumor node metastasis (TNM) staging, stoma site, thickness of rectus abdominis muscle (TRAM), C-reactive protein CRP, american society of anesthesiologists physical status classification (ASA), and stoma diameter. These insights from SHAP plots illustrated how these factors influence individual PSH outcomes. The nomogram was used for model visualization. CONCLUSION: The Random Forest model demonstrated robust predictive performance and clinical relevance in forecasting colonic PSH. This model aids in early identification of high-risk patients and guides preventive care.

Current Management of Diverticulitis.

Over the last few decades, our understanding of the pathophysiology and natural history of sigmoid diverticulitis has greatly improved. This knowledge has challenged many of the traditional principles in the management for diverticulitis, such as routine antibiotic administration in all cases, number-based recommendations for elective surgery, and the necessity for an end colostomy in emergency surgery. This review will cover the breadth of management for sigmoid diverticulitis, covering both uncomplicated and complicated disease as well as elective and emergent disease presentations. New and emerging concepts in management will be highlighted with a particular focus on level-1 data, when available.

Qualitative exploration of home life experiences and care needs among elderly patients with temporary intestinal stomas.

BACKGROUND: This study employed a phenomenological research approach within qualitative research to explore the challenges encountered by elderly individuals with temporary colostomies in managing their daily lives and care needs. Protecting the anus surgery combined with temporary colostomy has emerged as a prevalent treatment modality for low rectal cancer. However, the ileostomy is susceptible to peri-stoma skin complications, as well as fluid, electrolyte, and nutritional imbalances, posing challenges to effective management. The successful self-management of patients is intricately linked to their adjustment to temporary colostomy; nonetheless, there remains a dearth of research examining the factors influencing self-care among temporary colostomy patients and the obstacles they confront. AIM: To investigate the lived experiences, perceptions, and care requirements of temporary colostomy patients within their home environment, with the ultimate goal of formulating a standardized management protocol. METHODS: Over the period of June to August 2023, a purposive sampling technique was utilized to select 12 patients with temporary intestinal stomas from a tertiary hospital in Shanghai, China. Employing a phenomenological research approach, a semi-structured interview guide was developed, and qualitative interviews were conducted using in-depth interview techniques. The acquired data underwent coding, analysis, organization, and summarization following Colaizzi's seven-step method. RESULTS: The findings of this study revealed that the experiences and needs of patients with temporary intestinal stomas can be delineated into four principal themes: Firstly, Temporary colostomy patients bear various burdens and concerns about the uncertainty of disease progression; secondly, patients exhibit limited self-care capabilities and face information deficits, resulting in heightened reliance on healthcare professionals; thirdly, patients demonstrate the potential for internal motivation through proactive self-adjustment; and finally, patients express a significant need for emotional and social support. CONCLUSION: Home-living patients with temporary intestinal stomas confront multifaceted challenges encompassing burdens, inadequate self-care abilities, informational deficits, and emotional needs. Identifying factors influencing patients' self-care at home and proposing strategies to mitigate barriers can serve as a foundational framework for developing and implementing nursing interventions tailored to the needs of patients with temporary intestinal stomas.

HIV-associated rectovaginal fistulae in children: a single-centre retrospective study in the antiretroviral era.

PURPOSE: Acquired rectovaginal fistulae (RVF) are a complication of paediatric HIV infection. We report our experience with the surgical management of this condition. METHODS: We retrospectively reviewed the records of paediatric patients with HIV-associated RVF managed at Chris Hani Baragwanath Academic Hospital (2011-2023). Information about HIV management, surgical history, and long-term outcomes was collected. RESULTS: Ten patients with HIV-associated RVF were identified. Median age of presentation was 2 years (IQR: 1-3 years). Nine patients (9/10) underwent diverting colostomy, while one demised before the stoma was fashioned. Fistula repair was performed a median of 17 months (IQR: 7.5-55 months) after colostomy. An ischiorectal fat pad was interposed in 5/9 patients. Four (4/9) patients had fistula recurrence, 2/9 patients developed anal stenosis, and 3/9 perineal sepsis. Stoma reversal was performed a median of 16 months (IQR: 3-25 months) after repair. Seven patients (7/9) have good outcomes without soiling, while 2/9 have long-term stomas. Failure to maintain viral suppression after repair was significantly associated with fistula recurrence and complications (φ = 0.8, p < 0.05). CONCLUSION: While HIV-associated RVFs remain a challenging condition, successful surgical treatment is possible. Viral suppression is a necessary condition for good outcomes.

Complications in spinal cord injury persons with "traditional" colostomy: a case series.

INTRODUCTION: Neurogenic bowel dysfunction is a frequent consequence of spinal cord injury/disease (SCI/D). A colostomy is considered when conservative treatments fail [1, 2]. In the last year we observed several SCI/D persons with colostomy, admitted to our institution with multiple complications. CASE PRESENTATION: We present four cases of SCI/D persons treated with Hartmann's procedure and admitted to our institution for pressure ulcer (PU) treatment. All patients underwent PU surgery with good results. All patients reported a subjective good evacuation setting. No one assumed laxative therapies at home. At admission, all patients underwent abdominal radiography that showed an important constipation, with cases of sub-occlusion or complete occlusion with gastroparesis. One person presented a parastomal, strangulated hernia and underwent hernia reduction and patch positioning around the stoma. During hospital stay, bowel management required an important administration of laxatives and frequent, almost daily, stoma washes. DISCUSSION: Some considerations must be made regarding the use of traditional techniques in SCI/D people, such as Hartmann's, leaving a large part of the colon and the anatomical position of the stoma itself represent limitations to fecal progression and may cause constipation. A specific approach, tailored on the SCI/D patients' characteristics, such as the one described by our group, should be considered. Even if colostomy has been performed, appropriate therapies and health education on how to manage the stoma are fundamental to prevent complications.

A case of small bowel evisceration through the rectum and anus.

A 46-year-old man presented with a small bowel prolapsing through the anus after straining on the toilet, which was starting to become ischaemic. He admitted to inserting a plastic object in his rectum about half an hour before straining. The bowel was kept moist by placing an intravenous drip line with saline dripping onto a wet swab. In theatre, the bowel was found to be prolapsing through a hole in the upper rectum and out through the anus. It was reduced back into the abdominal cavity through the same perforation, which was 4 cm long, without needing to extend it. This was sutured with polydioxanone (PDS) 2-0 as there was no contamination with faeces or pus. Due to improvement in the appearance of a small bowel and an extremely bruised mesentery, a re-look was planned in 24 hours. At the re-look the small bowel appeared healthy, therefore no resection was performed. However, a loop colostomy was fashioned to protect the upper rectal perforation repair. This shows that resection is not always required in such cases.

Enhancing drug therapy in ostomy patients: Best practice recommendations for medication management.

BACKGROUND: Ostomy surgery is a common procedure that poses various challenges for patients and healthcare professionals. There are numerous guidelines addressing different ostomy-related problems (ORPs) and supporting an interdisciplinary approach for ostomy care, but evidence-based literature for optimizing drug therapy after ostomy surgery is lacking. AIM: To investigate and characterize typical ORPs in relation to drug therapy and provide best practice recommendations from a pharmaceutical point of view. METHODS: Patients with an ileo- or colostomy were consecutively enrolled in a prospective, interventional monocentric cohort study during hospitalization, with particular attention to medication. A clinical pharmacist assessed DRPs by performing level 3 medication reviews and patient interviews. Pharmacists' interventions (PIs) were evaluated by two senior clinical pharmacists and documented in DokuPIK (Documentation of Pharmacists' Interventions in the Hospital). Following interdisciplinary discussions, physicians either accepted or rejected the proposed changes in drug therapy. Comparisons were made between ileostomy and colostomy patients regarding type and extent of PIs. RESULTS: Out of the 80 patients included in the cohort, 54 (67.5%) had an ileostomy and 26 (32.5%) a colostomy. In this study, 288 PIs were documented (234 ileostomy vs. 54 colostomy), of wich 94.0% were accepted and implemented by the physicians. The most common reason for PIs in both subgroups (29.6% ileostomy vs. 26.1% colostomy) was a missing drug although indicated (e.g. no loperamide, but high stoma output). The proportion of PIs associated with the ostomy was higher in ileostomy patients (48.3% ileostomy vs. 31.5% colostomy; p = 0.025). Typical ORPs were extracted and analyzed as case studies including recommendations for their respective management and prevention. CONCLUSION: This study highlights the importance of clinical pharmacists being a part of interdisciplinary teams to collaboratively improve ostomy care and patient safety. Especially ileostomy patients are more vulnerable for ORPs in the context of drug therapy and need to be monitored carefully.

Rectal perforation after laser hemorrhoidoplasty: a case report.

This case report outlines the intricate management of rectal perforation following laser hemorrhoidoplasty in a 31-year-old female, leading to an acute abdomen, sepsis, and multiorgan failure. Urgent laparoscopic exploration and the establishment of a double-loop colostomy were undertaken, marking the beginning of a complex course characterized by relapsed pelvic sepsis. Laser hemorrhoidoplasty has gained widespread acceptance for its minimally invasive approach in treating hemorrhoids. Remarkably, to our knowledge, the case we present is the first major complication reported after laser hemorrhoidoplasty, likely attributed to collateral thermic and mechanical tissue damage.

Fournier's gangrene originating from the perianal region or the urogenital area: does it make a difference?

OBJECTIVE: Fournier's gangrene (FG) is a rare and serious disorder which is associated with high mortality. In the literature, there is no study evaluating clinician-, patient- and disease-related factors affecting disease outcomes according to aetiological variation in FG. In our study, laboratory results and Uludag Fournier's Gangrene Severity Index (UFGSI) score, clinical characteristics and mortality rates were compared between FG originating from perianal or from urogenital regions. METHOD: Platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) and UFGSI risk scores were calculated in patients with FG at presentation to the emergency department. The patients were assigned to two groups according to FG aetiology. RESULTS: It was observed that the number of debridement interventions and the need for colostomy were significantly greater in the perianal FG group, while the need for flap or reconstruction was significantly (p=0.002) higher in the genitourinary FG group. No significant difference was detected in mortality between groups and the difference in aetiology had no significant effect on the results of the neutrophil-to-lymphocyte ratio, LRINEC or UFGSI scores. CONCLUSION: Laboratory results and UFGSI score were helpful in assessing disease severity independently from aetiology. The higher number of debridement interventions to protect anal function in the perianal group and the greater need for reconstructive surgery in the urogenital group were identified as factors that prolonged length of hospital stay.

Effect of Sublay Preventive Mesh for Terminal Colostomy on Symptoms and Quality of Life in Patients With Parastomal Hernia: A Post Hoc Analysis of the GRECCAR 7 Cohort.

BACKGROUND: Recent randomized clinical trials and meta-analyses confirm that the use of a prophylactic mesh does not significantly reduce the parastomal hernia rate. Data about the benefits of these meshes concerning the symptoms of parastomal hernia are lacking in the existing literature. OBJECTIVE: The aim of this study was to perform a post hoc analysis of the patients presenting parastomal hernia from the GRECCAR 7 (Groupe de recherche sur la chirurgie du cancer du rectum) randomized clinical trials cohort on whether the presence or the absence of the mesh influenced the symptoms, the quality of life, and complications of patients with parastomal hernias. DESIGN: We studied the parastomal hernia-related symptoms among the 2 groups of the GRECCAR 7 randomized clinical trial, with or without prophylactic mesh at the time of the index surgery. SETTINGS: Data were retrospectively extracted and analyzed from the GRECCAR 7 database. PATIENTS: Patients diagnosed with a parastomal hernia during the 2 years of the GRECCAR 7 study. MAIN OUTCOME MEASURES: Several prospectively collected data about the symptoms were studied among this population. We also studied the average interval between parastomal hernia repair surgery and both index surgery and diagnosis of parastomal hernia. RESULTS: Among the 199 patients included in the GRECCAR study, 36 patients (35.6%) in the nonmesh group and 33 patients (33.7%) in the mesh group were diagnosed with clinical and/or radiological parastomal hernia at 2-year follow-up, without a statistically significant difference ( p = 0.89). None of the studied symptoms showed any statistically significant difference between the groups. LIMITATIONS: This study relies on a relatively small number of patients, and although data were prospectively collected, we lacked some details about the categorization of parastomal hernias. CONCLUSIONS: We believe that the use of a prosthetic mesh in a sublay position to prevent parastomal hernia in terminal end colostomy patients should no longer be recommended. See Video Abstract . EFECTO DE LA MALLA PREVENTIVA RETROMUSCULAR PARA COLOSTOMA TERMINAL CON RESPECTO A LOS SNTOMAS Y LA CALIDAD DE VIDA EN PACIENTES CON HERNIA PARAESTOMAL UN ANLISIS POSTHOC DE LA COHORTE GRECCAR: ANTECEDENTES:Los recientes metaanálisis y ensayos clínicos aleatorizados confirman que el uso de una malla profiláctica no reduce significativamente la tasa de hernia paraestomal. En la literatura existente faltan datos sobre los beneficios de estas mallas en relación con los síntomas de la hernia paraestomal.OBJETIVO:El objetivo de este estudio fue realizar un análisis post-hoc de los pacientes que presentaron hernia paraestomal de la cohorte de 7 ensayos clínicos aleatorizados GRECCAR sobre si la presencia o ausencia de la malla influyó en los síntomas, la calidad de vida y las complicaciones de los pacientes con hernias paraestomales.DISEÑO:Estudiamos los síntomas relacionados con la hernia paraestomal entre los dos grupos del ensayo clínico aleatorizado GRECCAR 7, con o sin malla profiláctica en el momento de la cirugía índice.AJUSTES:Los datos fueron extraídos y analizados de manera retrospectiva de la base de datos GRECCAR 7.PACIENTES:Pacientes diagnosticados con hernia paraestomal durante los dos años del estudio GRECCAR 7.PRINCIPALES MEDIDAS DE RESULTADO:Se estudiaron varios datos recopilados de manera prospectiva sobre los síntomas en esta población. También estudiamos el intervalo promedio entre la cirugía reparadora de la hernia paraestomal así como también la cirugía índice como el diagnóstico de la hernia paraestomal.RESULTADOS:De entre los 199 pacientes incluidos en el estudio GRECCAR, 36 pacientes (35,6%) fueron diagnosticados con hernia paraestomal de manera clínica y/o radiológica en el grupo sin malla a los 2 años de seguimiento y 33 (33,7%) en el grupo con malla, sin diferencia estadísticamente significativa ( p = 0,89). Ninguno de los síntomas estudiados mostró diferencias estadísticamente significativas entre los grupos.LIMITACIONES:Este estudio se basa en un número relativamente pequeño de pacientes y, aunque los datos fueron recopilados de forma prospectiva, nos faltaron algunos detalles sobre la categorización de las hernias paraestomales.CONCLUSIONES:Creemos que ya no se debe recomendar el uso de una malla protésica en posición retromuscular para prevenir la hernia paraestomal en pacientes con colostomía terminal.

Low Hartmann's procedure versus abdominoperineal resection for rectal cancer, a propensity score matching cohort study.

BACKGROUND: This study aimed to compare low Hartmann's procedure (LHP) with abdominoperineal resection (APR) for rectal cancer (RC) regarding postoperative complications. METHOD: RC patients receiving radical LHP or APR from 2015 to 2019 in our center were retrospectively enrolled. Patients' demographic and surgical information was collected and analyzed. Propensity score matching (PSM) was used to balance the baseline information. The primary outcome was the incidence of major complications. All the statistical analysis was performed by SPSS 22.0 and R. RESULTS: 342 individuals were primarily included and 134 remained after PSM with a 1:2 ratio (50 in LHP and 84 in APR). Patients in the LHP group were associated with higher tumor height (P < 0.001). No significant difference was observed between the two groups for the incidence of major complications (6.0% vs. 1.2%, P = 0.290), and severe pelvic abscess (2% vs. 0%, P = 0.373). However, the occurrence rate of minor complications was significantly higher in the LHP group (52% vs. 21.4%, P < 0.001), and the difference mainly lay in abdominal wound infection (10% vs. 0%, P = 0.006) and bowel obstruction (16% vs. 4.8%, P = 0.028). LHP was not the independent risk factor of pelvic abscess in the multivariate analysis. CONCLUSION: Our data demonstrated a comparable incidence of major complications between LHP and APR. LHP was still a reliable alternative in selected RC patients when primary anastomosis was not recommended.

Outcomes comparison of robotic-assisted versus laparoscopic and open surgery for patients undergoing rectal cancer resection with concurrent stoma creation.

BACKGROUND: Despite widespread adoption of robotic-assisted surgery (RAS) in rectal cancer resection, there remains limited knowledge of its clinical advantage over laparoscopic (Lap) and open (OS) surgery. We aimed to compare clinical outcomes of RAS with Lap and OS for rectal cancer. METHODS: We identified all patients aged ≥ 18 years who had elective rectal cancer resection requiring temporary or permanent stoma formation from 1/2013 to 12/2020 from the PINC AI™ Healthcare Database. We completed multivariable logistic regression analysis accounting for hospital clustering to compare ileostomy formation between surgical approaches. Next, we built inverse probability of treatment-weighted analyses to compare outcomes for ileostomy and permanent colostomy separately. Outcomes included postoperative complications, in-hospital mortality, discharge to home, reoperation, and 30-day readmission. RESULTS: A total of 12,787 patients (OS: 5599 [43.8%]; Lap: 2872 [22.5%]; RAS: 4316 [33.7%]) underwent elective rectal cancer resection. Compared to OS, patients who had Lap (OR 1.29, p < 0.001) or RAS (OR 1.53, p < 0.001) were more likely to have an ileostomy rather than permanent colostomy. In those with ileostomy, RAS was associated with fewer ileus (OR 0.71, p < 0.001) and less bleeding (OR 0.50, p < 0.001) compared to Lap. In addition, RAS was associated with lower anastomotic leak (OR 0.25, p < 0.001), less bleeding (OR 0.51, p < 0.001), and fewer blood transfusions (OR 0.70, p = 0.022) when compared to OS. In those patients who had permanent colostomy formation, RAS was associated with fewer ileus (OR 0.72, p < 0.001), less bleeding (OR 0.78, p = 0.021), lower 30-day reoperation (OR 0.49, p < 0.001), and higher discharge to home (OR 1.26, p = 0.013) than Lap, as well as OS. CONCLUSION: Rectal cancer patients treated with RAS were more likely to have an ileostomy rather than a permanent colostomy and more enhanced recovery compared to Lap and OS.

Meta-analysis: loop ileostomy versus colostomy to prevent complications of anterior resection for rectal cancer.

PURPOSE: Anastomotic leakage is a serious complication of colorectal cancer surgery, prolonging hospital stays and impacting patient prognosis. Preventive colostomy is required in patients at risk of anastomotic fistulas. However, it remains unclear whether the commonly used loop colostomy(LC) or loop ileostomy(LI) can reduce the complications of colorectal surgery. This study aims to compare perioperative morbidities associated with LC and LI following anterior rectal cancer resection, including LC and LI reversal. METHODS: In this meta-analysis, the Embase, Web of Science, Scopus, PubMed, and Cochrane Library databases were searched for prospective cohort studies, retrospective cohort studies, and randomized controlled trials (RCTs) on perioperative morbidity during stoma development and reversal up to July 2023, The meta-analysis included 10 trials with 2036 individuals (2 RCTs and 8 cohorts). RESULTS: No significant differences in morbidity, mortality, or stoma-related issues were found between the LI and LC groups after anterior resection surgery. However, patients in the LC group exhibited higher rates of stoma prolapse (RR: 0.39; 95%CI: 0.19-0.82; P = 0.01), retraction (RR: 0.45; 95%CI: 0.29-0.71; P < 0.01), surgical site infection (RR: 0.52; 95%CI: 0.27-1.00; P = 0.05) and incisional hernias (RR: 0.53; 95%CI: 0.32-0.89; P = 0.02) after stoma closure compared to those in the LI group. Conversely, the LI group showed higher rates of dehydration or electrolyte imbalances(RR: 2.98; 95%CI: 1.51-5.89; P < 0.01), high-output(RR: 6.17; 95%CI: 1.24-30.64; P = 0.03), and renal insufficiency post-surgery(RR: 2.51; 95%CI: 1.01-6.27; P = 0.05). CONCLUSION: Our study strongly recommends a preventive LI for anterior resection due to rectal cancer. However, ileostomy is more likely to result in dehydration, renal insufficiency, and intestinal obstruction. More multicenter RCTs are needed to corroborate this.

Long-term restoration of bowel continuity after rectal cancer resection and the influence of surgical technique: A nationwide cross-sectional study.

AIM: Literature on nationwide long-term permanent stoma rates after rectal cancer resection in the minimally invasive era is scarce. The aim of this population-based study was to provide more insight into the permanent stoma rate with interhospital variability (IHV) depending on surgical technique, with pelvic sepsis, unplanned reinterventions and readmissions as secondary outcomes. METHOD: Patients who underwent open or minimally invasive resection of rectal cancer (lower border below the sigmoid take-off) in 67 Dutch centres in 2016 were included in this cross-sectional cohort study. RESULTS: Among 2530 patients, 1470 underwent a restorative resection (58%), 356 a Hartmann's procedure (14%, IHV 0%-42%) and 704 an abdominoperineal resection (28%, IHV 3%-60%). Median follow-up was 51 months. The overall permanent stoma rate at last follow-up was 50% (IHV 13%-79%) and the unintentional permanent stoma rate, permanent stoma after a restorative procedure or an unplanned Hartmann's procedure, was 11% (IHV 0%-29%). A total of 2165 patients (86%) underwent a minimally invasive resection: 1760 conventional (81%), 170 transanal (8%) and 235 robot-assisted (11%). An anastomosis was created in 59%, 80% and 66%, with corresponding unintentional permanent stoma rates of 12%, 24% and 14% (p = 0.001), respectively. When corrected for age, American Society of Anesthesiologists classification, cTNM, distance to the anorectal junction and neoadjuvant (chemo)radiotherapy, the minimally invasive technique was not associated with an unintended permanent stoma (p = 0.071) after a restorative procedure. CONCLUSION: A remarkable IHV in the permanent stoma rate after rectal cancer resection was found. No beneficial influence of transanal or robot-assisted laparoscopy on the unintentional permanent stoma rate was found, although this might be caused by the surgical learning curve. A reduction in IHV and improving preoperative counselling for decision-making for restorative procedures are required.

Postoperative morbidity following Hartmann's procedure in comparison to anterior resection and abdominoperineal resection for rectal cancer-a population-based study.

AIM: There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. METHODS: All patients operated for rectal cancer, tumour height 5-15 cm, between the years 2010 and 2017, were identified through the Swedish colorectal cancer registry. RESULTS: A total of 8476 patients were included: 1210 (14%) undergoing HP, 5406 (64%) AR and 1860 (22%) APR. HP was associated with an increased risk of intra-abdominal infection (OR 1.7, CI 1.26-2.28, P = 0.0004) compared to AR and APR, while APR was related to an increased risk of overall complications (OR 1.18, CI 1.01-1.40, P = 0.040). No significant difference was observed in the rate of reoperations and readmissions between HP, AR and APR, and type of surgical procedure was not a risk factor for 30-day mortality. Findings from a subgroup analysis of patients with a tumour 5-7 cm from the anal verge revealed that HP was not associated with increased risk for complications or 30-day mortality. CONCLUSIONS: For patients where AR is not appropriate HP is a valid alternative with a favourable outcome. APR was associated with the highest overall 30-day complication rate.

Effects of a perioperative educational pathway on ostomy self-care, level of independence and need for visiting nurse services: a comparative observational cohort study.

AIM: Most new ostomy patients are not able to manage ostomy self-care when they are discharged and rely on visiting nurse services for ostomy care. The aim of this study was to determine if a perioperative ostomy educational pathway increases the level of independence and decreases the need for visiting nurse services in new ostomy patients. METHOD: A prospective longitudinal study was conducted between July 2018 and February 2020. Patients who received a colostomy or ileostomy and were treated on the surgery ward were included. Patients who followed a perioperative ostomy educational pathway were compared to a historical control group. The primary outcome measure was the level of independence in ostomy care and the need for visiting nurse services. RESULTS: After discharge, 67.6% of patients in the intervention group (n = 244) were able to independently perform ostomy care and were therefore not relying on visiting nurse services, compared to 15.2% of the patients in the control group (n = 33). The need for visiting nurse services was higher in patients aged ≥70 years (OR 3.20, P < 0.001), those who did not attend the preoperative practice session (OR 3.02, P = 0.002), those with a history of transient ischaemic attack (OR 10.22, P = 0.045) and those with mild cognitive impairment (OR 28.98, P = 0.002). CONCLUSION: A perioperative ostomy educational pathway effectively increased the level of independence and decreased the need for visiting nurse services in new ostomy patients.
