BackgroundThis study aimed to evaluate outcome of children on chronic peritoneal dialysis (PD) with a concurrent colostomy.MethodsPatients were identified through the International Pediatric Peritoneal Dialysis Network (IPPN) registry. Matched controls were randomly selected from the registry. Data were collected through the IPPN database and a survey disseminated to all participating sites.ResultsFifteen centers reported 20 children who received chronic PD with a co-existing colostomy. The most common cause of end stage kidney disease was congenital anomalies of the kidney and urinary tract (n = 16, 80%). The main reason for colostomy placement was anorectal malformation (n = 13, 65%). The median age at colostomy creation and PD catheter (PDC) insertion were 0.1 (IQR, 0–2.2) and 2.8 (IQR 0.2–18.8) months, respectively. The colostomies and PDCs were present together for a median 18 (IQR, 4.9–35.8) months. The median age at PDC placement in 46 controls was 3.4 (IQR, 0.2–7.4) months of age. Fourteen patients (70%) developed 39 episodes of peritonitis. The annualized peritonitis rate was significantly higher in the colostomy group (1.13 vs. 0.70 episodes per patient year; p = 0.02). Predominant causative microorganisms were Staphylococcus aureus (15%) and Pseudomonas aeruginosa (13%). There were 12 exit site infection (ESI) episodes reported exclusively in colostomy patients. Seven colostomy children (35%) died during their course of PD, in two cases due to peritonitis.ConclusionAlthough feasible in children with a colostomy, chronic PD is associated with an increased risk of peritonitis and mortality. Continued efforts to reduce infection risk for this complex patient population are essential.

Following surgery for rectal cancer, two unfortunate outcomes for patients are permanent colostomy and local recurrence of cancer. We tested whether a quality-improvement strategy to change surgical practice would improve these outcomes. Sixteen hospitals were cluster-randomized to the intervention (Quality Initiative in Rectal Cancer strategy) or control (normal practice) arm. Consecutive patients with primary rectal cancer were accrued from May 2002 to December 2004. Surgeons at hospitals in the intervention arm could voluntarily participate by attending workshops, using opinion leaders, inviting a study team surgeon to demonstrate optimal techniques of total mesorectal excision, completing postoperative questionnaires, and receiving audits and feedback. Main outcome measures were hospital rates of permanent colostomy and local recurrence of cancer. A total of 56 surgeons (n = 558 patients) participated in the intervention arm and 49 surgeons (n = 457 patients) in the control arm. The median follow-up of patients was 3.6 years. In the intervention arm, 70% of surgeons participated in workshops, 70% in intraoperative demonstrations and 71% in postoperative questionnaires. Surgeons who had an intraoperative demonstration provided care to 86% of the patients in the intervention arm. The rates of permanent colostomy were 39% in the intervention arm and 41% in the control arm (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.63–1.48). The rates of local recurrence were 7% in the intervention arm and 6% in the control arm (OR 1.06, 95% CI 0.68–1.64). Despite good participation by surgeons, the resource-intense quality-improvement strategy did not reduce hospital rates of permanent colostomy or local recurrence compared with usual practice.

Background Hartmann's procedure is a commonly performed operation for complicated left colon diverticulitis or malignancy. The timing for reversal of Hartmann's is not well defined as it is technically challenging and carries a high complication rate. Methods This study is a retrospective audit of all patients who underwent Hartmann's procedure between 2008 and 2014. Reversal of Hartmann's rate, timing, American Society of Anesthesiologists grade, length of stay and complications (Clavien-Dindo) including 30-day mortality were recorded. Results Hartmann's procedure (n = 228) indications were complicated diverticular disease 44% (n = 100), malignancy 32% (n = 74) and other causes 24%, (n = 56). Reversal of Hartmann's rate was 47% (n = 108). Median age of patients was 58 years (range 21-84 years), American Society of Anesthesiologists grade 2 (range 1-4), length of stay was eight days (range 2-42 days). Median time to reversal of Hartmann's was 11 months (range 4-96 months). The overall complication rate from reversal of Hartmann's was 21%; 3.7% had a major complication of IIIa or above including three anastomotic leaks and one deep wound dehiscence. Failure of reversal and permanent stoma was less than 1% (n = 2). Thirty-day mortality following Hartmann's procedure was 7% (n = 15). Where Hartmann's procedure wass not reversed, for 30% (n = 31) this was the patient's choice and 70% (n = 74) were either high risk or unfit. Conclusions Hartmann's procedure is reversed less frequently than thought and consented for. Only 46% of Hartmann's procedures were stoma free at the end of the audit period. The anastomotic complication rate of 1% is also low for reversal of Hartmann's procedure in this study.

Minimally invasive approach for reversal of Hartmann's procedure remains understudied. This study examined the outcomes associated with open and minimally invasive approaches for colostomy reversal in a national cohort. The 2012-2022 American College of Surgeons National Surgical Quality Improvement Program participant use file data was queried to identify all adult (≥18 years) patients undergoing elective open or minimally invasive colostomy takedown. Multivariable regression models were developed to assess the associations between operative modalities and outcomes of interest, including overall complications (cardiac, respiratory, infectious, wound, renal and thromboembolic postoperative sequelae as well as reoperation and transfusion), operative duration, postoperative length of stay, and 30-day Readmissions. Among the 20,163 patients who underwent colostomy takedown during the study period, 6,180 (30.7%) had a minimally invasive reversal. Utilization of minimally invasive colostomy reversal increased from 18.2% in 2012 to 41.9% in 2022 (nptrend < 0.001). Following risk adjustment, minimally invasive colostomy takedown was associated with reduced odds of overall complications compared to the open approach (AOR 0.56, 95% CI 0.51-0.62). The minimally invasive approach was associated with decremental operative duration by 16.9 minutes (95% CI 13.6 to 20.2 minutes) and postoperative length of stay by 1.70 days (95% CI 1.56 to 1.84 days), as well as decreased odds of 30-day readmission (AOR 0.75, 95% CI 0.67-0.85). Over the past decade, utilization of minimally invasive colostomy reversal has more than doubled and yielded lower overall complication rates compared to the open approach. Our findings suggest that the minimally invasive approach may be appropriate for colostomy takedown in suitable cases.

BackgroundCurrent guidelines recommend resection with primary anastomosis with diverting loop ileostomy over Hartmann’s procedure if deemed safe for acute diverticulitis. The primary objective of the current study was to compare the utilization of these strategies and describe nationwide ostomy closure patterns and readmission outcomes within 1 year of discharge.MethodsThis was a retrospective, population-based, cohort study of United States Hospitals reporting to the Nationwide Readmissions Database from January 2011 to December 2019. There were 35,774 patients identified undergoing non-elective primary anastomosis with diverting loop ileostomy or Hartmann’s procedure for acute diverticulitis. Rates of ostomy closure, unplanned readmissions, and complications were compared. Cox proportional hazards and logistic regression models were used to control for patient and hospital-level confounders as well as severity of disease.ResultsOf the 35,774 patients identified, 93.5% underwent Hartmann’s procedure. Half (47.2%) were aged 46–65 years, 50.8% female, 41.2% publicly insured, and 91.7% underwent open surgery. Primary anastomosis was associated with higher rates of 1-year ostomy closure (83.6% vs. 53.4%, p < 0.001) and shorter time-to-closure [median 72 days (Interquartile range 49–103) vs. 115 (86–160); p < 0.001]. Primary anastomosis was associated with increased unplanned readmissions [Hazard Ratio = 2.83 (95% Confidence Interval 2.83–3.37); p < 0.001], but fewer complications upon stoma closure [Odds Ratio 0.51 (95% 0.42–0.63); p < 0.001]. There were no differences in complications between primary anastomosis and Hartmann’s procedure during index admission [Odds Ratio = 1.13 (95% Confidence Interval 0.96–1.33); p = 0.137].ConclusionPatients who undergo primary anastomosis for acute diverticulitis are more likely to undergo ostomy reversal and experience fewer postoperative complications upon stoma reversal. These data support the current national guidelines that recommend primary anastomosis in appropriate cases of acute diverticulitis requiring operative treatment.

Background The use of a colonic stent as a bridge to surgery aims to provide patients with elective one-stage surgical resection while reducing stoma creation and postoperative complications. This study used meta-analytic techniques to compare the outcomes of stent use as a bridge to surgery and emergency surgery in the management of obstructive colorectal cancer. Methods A literature search of Medline, Embase, Cochrane controlled trials registry, and the Chinese Biomedical Literature Database was performed on all studies comparing stent as a bridge to surgery and emergency surgery for obstructive colorectal cancer. A meta-analysis of the included studies was carried out to identify the differences in outcomes between the two procedures. Results Eight studies matched the criteria for inclusion and reported on the outcomes of 601 patients, of whom 232 (38.6%) underwent stent insertion and 369 (61.4%) underwent emergency surgery. Fewer patients in the stent group needed intensive care (risk ratio [RR], 0.42; 95% confidence interval [CI], 0.19–0.93; p  = 0.03) and stoma creation (RR, 0.70; 95% CI, 0.50–0.99; p  = 0.04). The primary anastomosis rate in the stent group was higher (RR, 1.62; 95% CI, 1.21–2.16; p  = 0.001). Overall complications (RR, 0.42; 95% CI, 0.24–0.71; p  = 0.001), including anastomotic leakage (RR, 0.31; 95% CI, 0.14–0.69; p  = 0.004), were reduced by stent insertion. Stent placement before elective surgery did not adversely affect mortality and long-term survival. Conclusions The use of a stent as a bridge to surgery for obstructive left-sided colorectal cancer could increase the chance of primary anastomosis and reduce the need for stoma creation and postprocedural complications. Stent insertion before subsequent surgery has no effect on perioperative mortality and long-term survival.

Background Open Hartmann’s procedure has traditionally been the procedure of choice to treat complicated diverticulitis. We analyzed the ACS-NSQIP database to compare outcomes in patients who underwent emergent laparoscopic Hartmann’s procedure (LHP) to those who had an open Hartmann’s procedure (OHP). Study design Data analyzed from 2015 to 2019 using ICD-10 codes. Patients were matched on several important covariates using a propensity score matching method (PSM). Patients were matched in a 4:1 ratio of controls to cases based on the propensity score. Results We identified 5026, of which 456 had LHP and 4570 had OHP. PSM analysis yielded 369 LHP and 1476 OHP patients. LHP had lower rates of superficial surgical site infection (SSSI) compared to OHP (2.44% vs. 5.89%, p  = 0.007). LHP had similar post-operative outcomes compared to OHP, including 30-day mortality (5.15% vs. 2.98%, p  = 0.060), organ space surgical site infection (OSSSI) (14.36% vs. 12.60%, p  = 0.161), wound disruption (1.36% vs. 2.44%, p  = 0.349), median LOS (8 vs. 9 days, p  = 0.252), readmission within 30 days (11.92% vs. 8.67%, p  = 0.176), rate of reoperation (6.0 vs. 6.5%, p  = 0.897), and discharge to home (76% vs. 77%, p  = 0.992). LHP had longer operative times compared to OHP (median 129 vs. 118 min, p  < 0.0001). Conclusion The LHP is associated with lower rates of SSSI. However, it is not associated with lower rates of mortality, OSSSI, readmissions and reoperations within 30 days. Surgical times are longer in LHP. More studies are needed to determine whether LHP offers advantages in the long-term, particularly in rates of incisional hernia and colostomy closure.

PurposeDivided sigmoidostomy (DS) is the classic stoma for patients with anorectal malformations (ARM). Loop sigmoidostomies (LS) in ARM are associated with a higher risk of stoma prolapse and urinary tract infections (UTI). This is not clearly supported by literature. We compared our experience with both techniques.MethodsRetrospective study of ARM patients who underwent DS or LS between 2013 and 2023. We analysed demographics, associated malformations, intraoperative variables, oral intake and stoma functioning times, hospital stay, complications, prolapses, and UTI.ResultsOf 40 patients, 29 underwent open DS and 11 laparoscopic LS. Demographics, malformation type, associated anomalies, surgical time, intraoperative and anaesthetic complications were comparable. Postoperative complications were higher in DS than LS [14(48.3%) vs 1(9.1%), (p = 0.02)], mostly due to wound complications [12(41.3%) vs 0(0%), (p = 0.01)]; with 3 dehiscenses and 3 strictures reintervened. The hours to oral intake and stoma functioning were higher for DS [48(39–90) and 48(24–48) vs 24(24–48) and 24(24–24), (p < 0.05)], with more days of hospital stay [36(19–60) vs 8(5–10), (p = 0.001)]. Prolapses [1(3.4%) vs 1(9.1%)] and UTIs [3(10.3%) vs 1(9.1%) (p > 0.05)] were comparable.ConclusionLS in ARM patients have no higher risk of prolapse or UTI than DS. DS had more complications, mostly wound infections, strictures and dehiscenses.

ObjectiveThe optimal time for neonatal stoma closure is unclear and there have been calls for a trial to compare early and late surgery. The feasibility of such a trial will depend on the population of eligible infants and acceptability to families and health professionals. In this study, we aimed to determine current UK practice and characteristics of those undergoing stoma surgery.DesignA retrospective cohort study of neonates who had undergone stoma surgery (excluding anorectal malformations and Hirschsprung’s disease) using three national databases: the National Neonatal Research Database (NNRD, 2012–2019), British Association of Paediatric Surgeons Congenital Anomalies Surveillance System (BAPS-CASS, 2013–2014) and Hospital Episode Statistics–Admitted Patient Care (HES-APC, 2011–2018).Results1830 eligible neonates were identified from NNRD, 163 from BAPS-CASS, 2477 from HES-APC. Median (IQR) duration of stoma in days was 57 (36–80) in NNRD, 63 (41–130) in BAPS-CASS and 78 (55–122) for neonates identified from HES-APC. At the time of closure, there were low rates of invasive ventilation (13%), inotrope use (5%) and recent steroids use (4%). Infants who underwent earlier closure (<9 weeks) were less preterm (median 28 weeks vs 25 weeks), have higher birth weight (median 986 g vs 764 g) and more likely to have stoma complications (29% vs 5%).ConclusionThere are sufficient UK neonates undergoing stoma formation for a trial. Stoma closure is performed at around 2 months, with clinical stability, gestation, weight and stoma complications appearing to influence timing. The variation in practice we document indicates there is opportunity to optimise practice through a trial.

Many temporary stomas are never reversed leading to significantly worse quality of life. Recent evidence suggests a lower rate of reversal among minority patients. Our study aimed to elucidate disparities in national stoma closure rates by race, medical insurance status, and household income. Five years of data from the Nationwide Inpatient Sample (2008 to 2012) was used to identify the annual rates of stoma formation and annual rates of stoma closure. Stomas labeled as “permanent” or those created secondary to colorectal cancers were excluded. Temporary stoma closure rates were calculated, and differences were tested with the chi-square test. Separate analyses were performed by race/ethnicity, insurance status, and household income. Nationally representative estimates were calculated using discharge-level weights. The 5-year average annual rate of temporary stoma creation was 76,551 per year (46% colostomies and 54% ileostomies). The annual rate of stoma reversal was 50,155 per year that equated to an annual reversal rate of 65.5%. Reversal rates were higher among white patients compared with black patients (67% vs 56%, P < .001) and among privately insured patients compared with uninsured patients (88% vs 63%, P < .001). Reversal rates increased as the household income increased from 61% in the lowest income quartile to 72% in the highest quartile (P < .001). Stark disparities exist in national rates of stoma closure. Stoma closure is associated with race, insurance, and income status. This study highlights the lack of access to surgical health care among patients of minority race and low-income status.
