RESUMEN
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.

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.

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.

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.

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.

BACKGROUND: Clostridium difficile infection (CDI) has been described in the early post-operative phase after stoma reversal. This systematic review aimed to describe the incidence of CDI after stoma reversal and to identify pre-operative variables correlated with an increased risk of infection. METHODS: A systematic review of the literature was conducted according to the PRISMA guidelines in March 2024. Manuscripts were included if reported at least one patient with CDI-associated diarrhoea following stoma reversal (colostomy/ileostomy). The primary outcome of interest was the incidence of CDI; the secondary outcome was the comparison of clinical variables (age, sex, time to stoma reversal, neo-adjuvant and adjuvant therapies after index colorectal procedure) in CDI-positive versus CDI-negative patients. A meta-analysis was performed when at least three studies reported on those variables. RESULTS: Out of 43 eligible manuscripts, 1 randomized controlled trial and 10 retrospective studies were selected, including 17,857 patients (2.1% CDI). Overall, the mean age was 64.3 ± 11.6 years in the CDI group and 61.5 ± 12.6 years in the CDI-negative group (p = 0.51), with no significant difference in sex (p = 0.34). Univariable analyses documented that the mean time to stoma reversal was 53.9 ± 19.1 weeks in CDI patients and 39.8 ± 15.0 weeks in CDI-negative patients (p = 0.40) and a correlation between neo-adjuvant and adjuvant treatments with CDI (p < 0.001). A meta-analysis was performed for time to stoma reversal, age, sex, and neo-adjuvant therapies disclosing no significant differences for CDI (stoma delay, MD 11.59; 95%CI 24.32-1.13; age, MD 0.97; 95%CI 2.08-4.03; sex, OR1.11; 95%CI 0.88-1.41; neo-adjuvant, OR0.81; 95%CI 0.49-1.35). Meta-analysis including patients who underwent adjuvant therapy evidenced a higher risk of CDI (OR 2.88; 95%CI 1.01-8.17, p = 0.11). CONCLUSION: CDI occurs in approximately 2.1% of patients after stoma reversal. Although a trend of increased delay in stoma reversal and a correlation with chemotherapy were documented in CDI patients, the use of adjuvant therapy was the only possible risk factor documented on meta-analysis.

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.

BACKGROUND: Hartmann's reversal, a complex elective surgery, reverses and closes the colostomy in individuals who previously underwent a Hartmann's procedure due to colonic pathology like cancer or diverticulitis. It demands careful planning and patient optimisation to help reduce postoperative complications. Preoperative evaluation of body composition has been useful in identifying patients at high risk of short-term postoperative outcomes following colorectal cancer surgery. We sought to explore the use of our in-house derived Artificial Intelligence (AI) algorithm to measure body composition within patients undergoing Hartmann's reversal procedure in the prediction of short-term postoperative complications. METHODS: A retrospective study of all patients who underwent Hartmann's reversal within a single tertiary referral centre (Western) in Melbourne, Australia and who had a preoperative Computerised Tomography (CT) scan performed. Body composition was measured using our previously validated AI algorithm for body segmentation developed by the Department of Surgery, Western Precinct, University of Melbourne. Sarcopenia in our study was defined as a skeletal muscle index (SMI), calculated as Skeletal Muscle Area (SMA) /height2 < 38.5 cm2/m2 in women and < 52.4 cm2/m2 in men. RESULTS: Between 2010 and 2020, 47 patients (mean age 63.1 ± 12.3 years; male, n = 28 (59.6%) underwent body composition analysis. Twenty-one patients (44.7%) were sarcopenic, and 12 (25.5%) had evidence of sarcopenic obesity. The most common postoperative complication was surgical site infection (SSI) (n = 8, 17%). Sarcopenia (n = 7, 87.5%, p = 0.02) and sarcopenic obesity (n = 5, 62.5%, p = 0.02) were significantly associated with SSIs. The risks of developing an SSI were 8.7 times greater when sarcopenia was present. CONCLUSION: Sarcopenia and sarcopenic obesity were related to postoperative complications following Hartmann's reversal. Body composition measured by a validated AI algorithm may be a beneficial tool for predicting short-term surgical outcomes for these patients.

INTRODUCTION: Parastomal hernia (PSH) is the most common and challenging complication after stoma creation, with an estimated 50% incidence 2 years after the index surgery. Mesh repair is the treatment of choice. Laparoscopic and/or robotic approaches allow acceptable outcomes. MATERIALS AND METHODS: A systematic literature review from January 2012 to November 2023 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Embase, PubMed, and Scopus search were performed to select articles dealing with minimally invasive surgical treatment for PSH after end colostomy. RESULTS: 603 studies were found, and 24 were chosen. When compared to open surgery, laparoscopy showed decreased postoperative complications and recurrence. The main laparoscopic approaches are the keyhole (KH), the Sugarbaker (SB), and the sandwich technique. Continuous improvement in surgery, mesh technology, and surgeons' expertise led to an amelioration of surgical outcome and recurrence rate after repair. Recent studies showed comparable outcomes for SB and KH techniques, while novel surgical approaches have been proposed in an attempt to further increase the operative and long-term results. Reports on PSH robotic repairs are scarce and describe small series results, suggesting a role of the initial learning curve as a risk factor for complications. CONCLUSION: End-colostomy PSH surgical repair still represents a challenge for surgeons. Recent evidence has not shown a significant advantage in postoperative complications and recurrence with a specific repair among SB, KH, and sandwich technique. The paucity of data on robotic surgery does not allow to draw definitive conclusion. Further primary, multicentric, and larger cohort studies are needed.

BACKGROUND: Stoma prolapse (SP) is a common stoma-related complication, particularly in loop colostomies. This study aimed to investigate potential risk factors for SP development after laparoscopic loop colostomy. METHODS: In total, data from 140 patients who underwent laparoscopic loop colostomy were analyzed between September 2016 and March 2022. Risk factors for SP were investigated retrospectively. RESULTS: The median follow-up duration after colostomy was 12.5 months, and SP occurred in 33 (23.6%) patients. Multivariate analysis showed that being overweight (body mass index ≥ 25; odds ratio [OR], 8.69; 95% confidential interval [CI], 1.61-46.72; p = 0.012) and having a thin rectus abdominis penetration of the stoma (< 8.9 mm; OR, 8.22; 95% CI, 2.50-27.05; p < 0.001) were independent risk factors for SP. Other patient characteristics and surgical factors associated with stoma construction were unrelated to SP development. CONCLUSIONS: Being overweight and the route penetrating the thinner rectus abdominis during stoma construction was associated with a significantly higher incidence of SP after laparoscopic loop colostomy. Selecting a construction site that penetrates the thicker rectus abdominis muscle may be crucial for preventing SP.

BACKGROUND: Diversion colitis (DC) is a prevalent complication of colostomy characterized by intestinal inflammation. This study aimed to investigate the therapeutic potential of somatostatin (SST) in managing DC. METHODS: After establishing a rat DC model, SST was administered via Mini Osmotic Pumps 2001W at a pumping rate of 1.0 µL/h. Various techniques, including hematoxylin and eosin staining, periodic acid-Schiff staining, immunofluorescence staining, and electron microscopy were employed to assess the effects of SST. Intestinal barrier functions were evaluated using Evans blue, enzyme-linked immunosorbent assay, and MacConkey agar. RESULTS: After SST treatment, the significant weight loss and associated high mortality in the DC group were successfully mitigated. Upregulation of claudin-3 and claudin-4 restored mechanical barriers in colon epithelial tissue, whereas protection of goblet cells and stimulation of mucus secretion enhanced mucus barriers. SST effectively reduced leaky gut and alleviated systemic inflammation. CONCLUSION: This study provides initial evidence supporting the efficacy of SST in the treatment of DC. It offers insights into the role of SST in DC by elucidating its ability to restore damaged intestinal barriers.

BACKGROUND: Anorectal malformations (ARMs) are the most common congenital anomaly of the digestive tract. And colostomy should be performed as the first-stage procedure in neonates diagnosed with intermediate- or high-type ARMs. However, the most classic PeËna's colostomy still has some disadvantages such as complicated operation procedure, susceptibility to infection, a greater possibility of postoperative incision dehiscence, difficulty of nursing and large surgical trauma and incision scarring when closing the stoma. We aimed to explore the effectiveness of middle descending colon-double lumen ostomy (MDCDLO) in the treatment of high and intermediate types of anorectal malformations. METHODS: We retrospectively reviewed the data of patients who underwent MDCDLO for high or intermediate types of ARMs between June 2016 and December 2021 in our hospital. The basic characteristics were recorded. All patients were followed up monthly to determine if any complication happen. RESULTS: There were 17 boys and 6 girls diagnosed with high or intermediate types of ARMs in our hospital between June 2016 and December 2021. All 23 patients were cured without complications such as abdominal incision infection, stoma stenosis, incisional hernia, and urinary tract infection in the postoperative follow-up time of 6 months to 6 years except one case of proximal intestinal prolapse was restored under anesthesia. CONCLUSION: MDCDLO offers the advantages of simplicity, efficiency, safety, mild trauma, and small scarring in the treatment of high and intermediate types of anorectal malformations.

AIM: Approximately 4000 patients in the UK have an emergency intestinal stoma formed each year. Stoma-related complications (SRCs) are heterogeneous but have previously been subcategorized into early or late SRCs, with early SRCs generally occurring within 30 days postoperatively. Early SRCs include skin excoriation, stoma necrosis and high output, while late SRCs include parastomal hernia, retraction and prolapse. There is a paucity of research on specific risk factors within the emergency cohort for development of SRCs. This paper aims to describe the incidence of SRCs after emergency intestinal surgery and to identify potential risk factors for SRCs within this cohort. METHOD: Consecutive patients undergoing emergency formation of an intestinal stoma (colostomy, ileostomy or jejunostomy) were identified prospectively from across three acute hospital sites over a 3-year period from the ELLSA (Emergency Laparotomy and Laparoscopic Scottish Audit) database. All patients were followed up for a minimum of 1 year. A multivariate logistic regression model was used to identify risk factors for early and late SRCs. RESULTS: A total of 455 patients were included (median follow-up 19 months, median age 64 years, male:female 0.52, 56.7% ileostomies). Early SRCs were experienced by 54.1% of patients, while 51% experienced late SRCs. A total of 219 patients (48.1%) had their stoma sited preoperatively. Risk factors for early SRCs included end ileostomy formation [OR 3.51 (2.24-5.49), p < 0.001], while preoperative stoma siting was found to be protective [OR 0.53 (0.35-0.83), p = 0.005]. Patient obesity [OR 3.11 (1.92-5.03), p < 0.001] and reoperation for complications following elective surgery [OR 4.18 (2.01-8.69), p < 0.001] were risk factors for late SRCs. CONCLUSION: Stoma-related complications after emergency surgery are common. Preoperative stoma siting is the only truly modifiable risk factor to reduce SRCs, and further research should be aimed at methods of improving the frequency and accuracy of this in the emergency setting.

PURPOSE: Parastomal hernia (PH) stands out as a prevalent complication following end colostomies, significantly affecting patients' quality of life. Various surgical strategies, predominantly involving prophylactic mesh deployment, have been explored with variable outcomes. This study details our experience and mid-term outcomes utilizing a funnel-shaped mesh. METHODS: A single-center, prospective, non-randomized, observational study examined consecutive patients undergoing colorectal surgery with end colostomy, incorporating a 3D-funnel mesh from January 2019 to December 2021 (PM group). A historical cohort of patients with end colostomy without prophylactic mesh served as the comparison (C group). Postoperative morbidity within 30 days was documented, and clinical examinations and radiological tests were employed for parastomal hernia diagnosis during follow-up. RESULTS: Seventy-two patients participated, with thirty-four in the PM group and thirty-eight in the C group. The PM group experienced 16 postoperative complications, unrelated to the mesh, while the C group recorded 20 complications (p = 0.672). Median follow-up was 22.06 months for the PM group and 63.18 months for the C group. The PM group exhibited a lower parastomal hernia incidence during follow-up (8.8%) compared to the C group(68.4%) (p < 0.001). CONCLUSION: Prophylactic use of a 3D-funnel mesh appears effective in reducing parastomal hernia incidence in the short and mid-term, without an associated increase in postoperative morbidity.

BACKGROUND: Stoma reversal is associated with a relatively high risk of surgical site infection (SSI), occurring in up to 40% of cases. This may be explained by the presence of microorganisms around the stoma site, and possible contamination with the intestinal contents during the open-end manipulation of the bowel, making the stoma closure site a clean-contaminated wound. The conventional technique for stoma reversal is linear skin closure (LSC). The purse-string skin closure (PSSC) technique (circumferential skin approximation) creates a small opening in the centre of the wound, enabling free drainage of contaminants and serous fluid. This could decrease the risk of SSI compared with LSC. OBJECTIVES: To assess the effects of purse-string skin closure compared with linear skin closure in people undergoing stoma reversal. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, two other databases, and three trials registers on 21 December 2022. We also checked references, searched for citations, and contacted study authors to identify additional studies. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) comparing PSSC and LSC techniques in people undergoing closure of stoma (loop ileostomy, end ileostomy, loop colostomy, or end colostomy) created for any indication. DATA COLLECTION AND ANALYSIS: Two review authors independently selected eligible studies, extracted data, evaluated the methodological quality of the included studies, and conducted the analyses. The most clinically relevant outcomes were SSI, participant satisfaction, incisional hernia, and operative time. We calculated odds ratios (ORs) for dichotomous data and mean differences (MDs) for continuous data, each with its corresponding 95% confidence interval (CI). We used the GRADE approach to rate the certainty of the evidence. MAIN RESULTS: Nine RCTs involving 757 participants were eligible for inclusion. Eight studies recruited only adults (aged 18 years and older), and one study included people aged 12 years and older. The participants underwent elective reversal of either ileostomy (82%) or colostomy (18%). We considered all studies at high risk of performance and detection bias (lack of blinding) and four studies at unclear risk of selection bias related to random sequence generation. PSSC compared with LSC likely reduces the risk of SSI (OR 0.17, 95% CI 0.09 to 0.29; I2 = 0%; 9 studies, 757 participants; moderate-certainty evidence). The anticipated absolute risk of SSI is 52 per 1000 people who have PSSC and 243 per 1000 people who have LSC. The likelihood of being very satisfied or satisfied with stoma closure may be higher amongst people who have PSSC compared with people who have LSC (100% vs 89%; OR 20.11, 95% CI 1.09 to 369.88; 2 studies, 122 participants; low-certainty evidence). The results of the analysis suggest that PSSC compared with LSC may have little or no effect on the risk of incisional hernia (OR 0.51, 95% CI 0.07 to 3.70; I2 = 49%; 4 studies, 297 participants; very low-certainty evidence) and operative time (MD -2.67 minutes, 95% CI -8.56 to 3.22; I2 = 65%; 6 studies, 460 participants; very low-certainty evidence). AUTHORS' CONCLUSIONS: PSSC compared with LSC likely reduces the risk of SSI in people undergoing reversal of stoma. People who have PSSC may be more satisfied with the result compared with people who have LSC. There may be little or no difference between the skin closure techniques in terms of incisional hernia and operative time, though the evidence for these two outcomes is very uncertain.

AIM: Colostomy complication rates range widely from 10% to 70%. The psychological burden on patients, leading to lifestyle changes and decreased quality of life (QoL), is one of the largest factors. The aim of this work was to assess the history and efficacy of ostomy continence devices in improving continence and QoL. METHOD: In this PRISMA-compliant systematic review and meta-analysis, we searched PubMed, Scopus, Google Scholar and clinicaltrials.gov for studies on continence devices for all ostomies up to April 2023. Primary outcomes were continence and improvement in QoL. Secondary outcomes were leakage, patient's device preference and complications. Risk of Bias 2 and the revised tool to assess risk of bias in non-randomized studies of interventions (ROBINS-1) were used to assess risk of bias. Certainty of evidence was graded using GRADE. RESULTS: Twenty-two studies assessed devices from 1978 to 2022. The two main types identified were ball-valve devices and plug systems. Conseal and Vitala were the two main devices with significant evidence allowing for pooled analyses. Conseal, the only currently marketed device, had a pooled rate of continence of 67.4%, QoL improvement was 74.9%, patient preference over a traditional appliance was 69.1%, leakage was 10.1% and complications was 13.7%. Since 2011, five studies have investigated experimental devices on both human and animal models. CONCLUSION: Ostomy continence has been a long-standing goal without a consistently reliable solution. We propose that selective and short-term usage of continence devices may lead to improved continence and QoL in ostomy patients. Further research is needed to develop a reliable daily device for ostomy continence. Future investigation should include the needs of ileostomates.

Background: Colostomy is one of the common surgical procedures performed in pediatric surgical practice. The aim of this study was to retrospectively review our experience with colostomy and closure (reversal) in children. Patients and Methods: A retrospective review of the data of all children aged 15 years and below who had colostomy and colostomy closure in the past 5 years. Results: Of the 67 children who had colostomy 42 (62.7%) boys and 25 (37.3%) girls, with an age range between 13 months and 8 years. Fifty-six (83.6%) of the children were <2 years. Anorectal malformation 53 (79.1%) was the common indication. Divided colostomy was performed in 62 (92.5%) patients and loop colostomy was performed in 5 (7.5%) patients. All the patients had intraperitoneal colostomy closure. A complication rate of 26.4% was seen. Duration of hospital stay ranged between 4 and 10 days. No mortality was recorded. Conclusion: Colostomy reversal is a safe procedure but morbidity may ensure and can easily manage.
Résumé Contexte: La colostomie est l'une des interventions chirurgicales courantes pratiquées en chirurgie pédiatrique. Le but de cette étude était de revoir rétrospectivement notre expérience en matière de colostomie et de fermeture (inversion) chez les enfants. Méthode: Une revue rétrospective des données de tous les enfants âgés de 15 ans et moins ayant subi une colostomie et une fermeture de colostomie au cours des 5 dernières années. Résultats: Sur les 67 enfants ayant subi une colostomie, 42 (62,7 %) garçons et 25 (37,3 %) filles, avec une tranche d'âge comprise entre 13 mois et 8 ans. Cinquante-six (83,6 %) des enfants avaient moins de 2 ans. La malformation ano-rectale 53 (79,1 %) était l'indication fréquente. Une colostomie divisée a été réalisée chez 62 (92,5 %) patients et une colostomie en anse réalisée chez 5 (7,5 %) patients. Tous les patients ont eu une colostomie intrapéritonéale fermée. Un taux de complications de 26,4 % a été observé. La durée du séjour à l'hôpital variait entre 4 et 10 jours. Aucune mortalité enregistrée. Conclusion: l'inversion de la colostomie est une procédure sûre mais la morbidité peut être assurée et peut être facilement gérée.

OBJECTIVE: This study investigated the use of a modified laparoscopic repair of paraostomy hernia technique, called "D-Type parastomal hernia repair surgery" which combines abdominal wall and extraperitoneal stoma reconstruction, in patients with parastomal hernia (PSH) following colorectal stoma surgery. The aim was to determine whether D-type parastomal hernia repair surgery is a promising surgical approach compared to the traditional laparoscopic repair technique (Sugarbaker method) for patients with PSH. METHODS: PSH patients were selected and retrospectively divided into two groups: the study group underwent D-type parastomal hernia repair, while the control group underwent laparoscopic Sugarbaker repair. Clinical data from both groups were analyzed. RESULT: Compared to control group (n = 68), the study group undergoing D-type stoma lateral hernia repair had significant increase in total operative time (98.82 ± 12.37 min vs 124.61 ± 34.99 min, p < 0.001). The study group also showed better postoperative stoma bowel function scores in sensory ability, frequency of bowel movements, and clothing cleanliness without a stoma bag (p = 0.037, 0.001, 0.002). The treatment cost was significantly higher in the control group (3899.97 ± 260.00$ vs 3215.91 ± 230.03$, p < 0.001). The postoperative recurrence rate in the control group was 26.4%, while in the study group, it was 4.3%, with a significant statistical difference (p = 0.024). In terms of long-term postoperative complications, the study group had an overall lower incidence compared to the control group (p = 0.035). Other parameters showed no significant differences between the two groups. CONCLUSION: The study suggests that D-type parastomal hernia repair surgery is a safe and feasible procedure. Compared to traditional surgery, it can reduce the recurrence of lateral hernia, improve postoperative stoma bowel function, and save medical resources.
