Temporary diverting loop ileostomy in Crohn's disease surgery; indications and outcome.

Crohn's disease can present with complex surgical pathologies, posing a significant risk of morbidity and mortality for patients. The implementation of a loop ileostomy for selected patients may help minimize associated risks. In this retrospective cohort study, we investigated the utilization of temporary fecal diversion through the creation of a loop ileostomy in Crohn's surgery. Closure of all ostomies involved a hand-sewn single-layer technique. We then conducted bivariate analysis on 30-day outcomes for closures, focusing on favorable recovery defined as the restoration of bowel continuity without the occurrence of two challenges in recovery: newly developed organ dysfunction or the necessity for reoperation. In total, 168 patients were included. The median age of the patients was 38 years (IQR 27-51). The most common indication for a loop ostomy was peritonitis (49%). After ileostomy closure, 163 patients (97%) achieved favorable recovery, while five encountered challenges; four (2.4%) underwent abdominal surgery, and one (0.6%) developed acute renal failure requiring dialysis. Two patients (1.2%) had a re-creation of ileostomy. Patients encountering challenges were older (56 [IQR 41-61] vs. 37 [IQR 27-50]; p 0.039) and more often required secondary intention wound healing (40% vs. 6.7%; p 0.049) and postoperative parenteral nutrition following their index surgery (83% vs. 26%; p 0.006). Selectively staging the Crohn's disease operations with a loop ileostomy is a reliable practice with low morbidity and high restoration rates of bowel continuity. Our hand-sewn single-layer technique proves effective in achieving successful surgical recovery.

Pelvic Floor Rehabilitation After Rectal Cancer Surgery One-year follow-up of a Multicenter Randomized Clinical Trial (FORCE trial).

This study aims to evaluate the effects of pelvic floor rehabilitation (PFR) after low anterior resection (LAR) at one-year follow-up. After LAR, with restoration of bowel continuity, up to 90% of patients develop anorectal dysfunction, significantly impacting their quality of life. However, standardized treatment is currently unavailable. The FORCE trial demonstrated the beneficial effects of PFR after three months regarding specific domains of the Fecal Incontinence QoL (FIQL) questionnaire and urgency compared to usual care. The FORCE trial is a multicenter, two-arm, randomized clinical trial. All patients undergoing LAR were randomly assigned to receive either usual care or a standardized PFR program. The primary outcome measure is the Wexner incontinence score, and the secondary endpoints included the LARS score, the EORTC colorectal-specific QoL questionnaire, and health- and fecal incontinence-related QoL. Assessments were conducted at baseline before randomization, at three months and one-year follow-ups. A total of 86 patients were included (PFR: n=40, control: n=46). After one year, PFR did not significantly improve Wexner incontinence scores (PFR: -3.33, 95% CI -4.41 to -2.26, control: -2.54, 95% CI -3.54 to -1.54, P=0.30). Similar to the three-month follow-up, patients without near-complete incontinence at baseline showed sustained improvement in fecal incontinence (PFR: -2.82, 95% CI -3.86 to -1.76, control: -1.43, 95% CI -2.36 to -0.50, P=0.06). Significant improvement was reported in the FIQL domains Lifestyle (PFR: 0.51, control: -0.13, P=0.03) and Coping and Behavior (PFR: 0.40, control: -0.24, P=0.01). At one-year follow-up, no significant differences were found in fecal incontinence scores; however, PFR was associated with improved fecal incontinence related QoL compared to usual care.

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

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. 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. 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. 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.

Long-term bowel functional outcomes following anal sphincter-preserving surgery for upper and middle rectal cancer: a single-center longitudinal study.

Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients' quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer. In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included. Bowel function was assessed longitudinally with Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores every 6 months after restoration of bowel continuity. Patients with at least 2 follow-up visits were included. Overall, 100 patients received neoadjuvant chemoradiotherapy. Urgency, soilage, and fecal incontinence were noted within 24 months in the patients treated with neoadjuvant chemoradiotherapy. After 2 years of follow-up, significant bowel dysfunction and fecal incontinence were observed in the neoadjuvant chemoradiotherapy group. Low tumor level and neoadjuvant chemoradiotherapy were associated with delayed bowel dysfunction. Neoadjuvant chemoradiotherapy in combination with low tumor level was significantly associated with delayed bowel dysfunction even after 2 years of follow-up. Therefore, careful selection and discussion with patients are paramount.

Use of Biologics for the Treatment of Inflammatory Conditions of the Pouch: A Systematic Review.

Patients with medically-refractory ulcerative colitis or advanced neoplasia are often offered an ileal-pouch-anal anastomosis to restore bowel continuity. However, up to 50% of patients can suffer from inflammatory conditions of the pouch, some of which require biological therapy to treat. The aim of this study was to determine the efficacy of each biological agent for the treatment of inflammatory conditions of the pouch. A comprehensive literature search was performed in the major databases from inception through February 11, 2020, for studies assessing the efficacy of biologics in chronic antibiotic-refractory pouchitis (CARP) and Crohn's disease (CD) of the pouch. Both prospective and retrospective studies were included. The primary outcomes of interest were complete and partial responses were defined within each study. χ 2 test was used to compare variables. Thirty-four studies were included in the systematic review and meta-analysis. Sixteen studies (N=247) evaluated the use of infliximab (IFX), showing complete response in 50.7% and partial response in 28.1% for CARP, and complete response in 66.7% and partial response in 20% for CD of the pouch. Seven studies (n=107) assessed the efficacy of adalimumab. For CARP, 33.3% of patients had a complete response, and 38.1% had a partial response, whereas for CD of the pouch, 47.7% experienced a complete response, and 24.6% had a partial response. Three studies (n=78) reported outcomes with the use of ustekinumab, showing 50% complete response and 3.8% partial response for CARP. For the CD of the pouch, 5.8% had a complete response and 78.8% had a partial response. Seven studies (n=151) reported the efficacy of vedolizumab, showing 28.4% complete response and 43.2% partial response in patients with CARP, whereas 63% of patients experienced partial response in CD of the pouch. IFX had higher rates of complete response in CARP compared with adalimumab ( P =0.04) and compared with vedolizumab ( P =0.005), but not compared with ustekinumab ( P =0.95). There were no new safety signals reported in any of the studies. Biologics are safe and efficacious in the treatment of chronic, refractory inflammatory conditions of the pouch. IFX seems to be more efficacious than adalimumab and vedolizumab for CARP. Further prospective, head-to-head evaluations are needed to compare biological therapies in the treatment of CARP and CD of the pouch.

The impact of faecal diversion on the gut microbiome: a systematic review.

Diversion of the faecal stream is associated with diversion colitis (DC). Preliminary studies indicate that microbiome dysbiosis contributes to its development and potentially treatment. This review aims to characterise these changes in the context of faecal diversion and identify their clinical impact. A systematic search was conducted using MEDLINE, EMBASE and CENTRAL databases using a predefined search strategy identifying studies investigating changes in microbiome following diversion. Findings reported according to PRISMA guidelines. Of 743 results, 6 met inclusion criteria. Five reported significantly decreased microbiome diversity in the diverted colon. At phylum level, decreases in Bacillota with a concomitant increase in Pseudomonadota were observed, consistent with dysbiosis. At genus level, studies reported decreases in beneficial lactic acid bacteria which produce short-chain fatty acid (SCFA), which inversely correlated with disease severity. Significant losses in commensals were also noted. These changes were seen to be partially reversible with restoration of bowel continuity. Changes within the microbiome were reflected by histopathological findings suggestive of intestinal dysfunction. Faecal diversion is associated with dysbiosis in the diverted colon which may have clinical implications. This is reflected in loss of microbiome diversity, increases in potentially pathogenic-associated phyla and reduction in SCFA-producing and commensal bacteria.

Timing of restoration of bowel continuity after decompressing stoma, in left-sided obstructive colon cancer: a nationwide retrospective cohort.

With the increasing use of decompressing stoma as a bridge to surgery for left-sided obstructive colon cancer (LSOCC), the timing of restoration of bowel continuity (ROBC) is a subject of debate. There is a lack of data on immediate ROBC during elective resection as an alternative for a 3-stage procedure. This study analysed if immediate ROBC during tumour resection is safe and of any benefit for patients who underwent decompressing stoma for LSOCC. In a Dutch nationwide collaborative research project, 3153 patients who underwent resection for LSOCC in 75 hospitals (2009-2016) were identified. Extensive data on disease and procedural characteristics, and outcomes was collected by local collaborators. For this analysis, 332 patients who underwent decompressing stoma followed by curative resection were selected. Immediate ROBC during tumour resection was compared to two no immediate ROBC groups, (1) tumour resection with primary anastomosis (PA) with leaving the decompressing stoma in situ, and (2) tumour resection without PA. Immediate ROBC was performed in 113 patients (34.0%) and no immediate ROBC in 219 patients [168 with PA (50.6%) and 51 patients without PA (15.4%)]. No differences at baseline between the groups were found for age, ASA score, cT, and cM. Major surgical complications (8.8% immediate ROBC vs. 4.8% PA with decompressing stoma and 7.8% no PA; P =0.37) and mortality (2.7% vs. 2.4% and 0%, respectively; P =0.52) were similar. Immediate ROBC resulted in a shorter time with a stoma (mean 41 vs. 240 and 314 days, respectively; P <0.001), and fewer permanent stomas (7% vs. 21% and 80%, respectively; P <0.001) as compared to PA with a decompressing stoma or no PA. After a decompressing stoma for LSOCC, immediate ROBC during elective resection appears safe, reduces the total time with a stoma and the risk of a permanent stoma.

Anastomotic leakage and functional outcomes following total mesorectal excision with delayed and immediate colo-anal anastomosis for rectal cancer: Two single-arm phase II trials

BackgroundAnastomotic leakage (AL) remains a major cause of morbidity following total mesorectal excision (TME). A diverting ileostomy reduces the risk of AL but impairs quality of life (QoL). Delayed colo-anal anastomosis (DCAA) may be an alternative to immediate colo-anal anastomosis (ICAA) without creation of a diverting ileostomy. Study designPatients with T3 or N+ rectal tumours were treated with neoadjuvant chemoradiation and TME. To evaluate DCAA or ICAA with diverting ileostomy, a two multicenter single-arm phase II trials was designed. The primary endpoint was the rate of AL requiring a diverting ileostomy up to 30 days postoperatively. Secondary endpoints were 30-day postoperative complications, 1- and 2-year disease-free survival; QoL at baseline, 6 months and anorectal function measured by the low anterior resection syndrome questionnaire and Wexner score at baseline, 6 months and a late assessment at median 8 years following surgery. ResultsAL requiring diverting ileostomy occurred in one patient (2.1%; 95% confidence interval (CI) [0; 11.1]) in the DCAA group and in five patients (8.6%; 95%CI [3.2; 21.0]) in the ICAA group. Thirty-day postoperative complications occurred in 13 patients (27.1%) in the DCAA group and in 10 patients (19.2%) in the ICAA group. Short and long-term functional outcomes showed similar patterns. ConclusionThese two single-arm phase II trials showed that DCAA has low rates of AL requiring a diverting ileostomy and acceptable long-term functional results. DCAA seems a good choice to restore bowel continuity.

Temporary Faecal Diversion for Refractory Perianal and/or Distal Colonic Crohn's Disease in the Biologic Era: An Updated Systematic Review with Meta-analysis.

We evaluated short- and long-term outcomes of temporary faecal diversion [FD] for management of refractory Crohn's disease [CD], focusing on outcomes in the biologic era. Through a systematic literature review until March 15, 2023, we identified 33 studies [19 conducted in the biologic era] that evaluated 1578 patients with perianal and/or distal colonic CD who underwent temporary FD [with intent of restoring bowel continuity] and reported long-term outcomes [primary outcome: successful restoration of bowel continuity, defined as remaining ostomy-free after reconnection at a minimum of 6 months after diversion or at the end of follow-up]. We calculated pooled rates (with 95% confidence interval [CI]) using random effects meta-analysis, and examined factors associated with successful restoration of bowel continuity. Overall, 61% patients [95% CI, 52-68%; 50% in biologic era] experienced clinical improvement after FD. Stoma takedown was attempted in 34% patients [28-41%; 37% in biologic era], 6-18 months after diversion. Among patients where bowel restoration was attempted, 63% patients [54-71%] had successful restoration of bowel continuity, and 26% [20-34%] required re-diversion. Overall, 21% patients [17-27%; 24% in biologic era] who underwent FD were successfully restored; 34% patients [30-39%; 31% in biologic era] required proctectomy with permanent ostomy. On meta-regression, post-diversion biologic use and absence of proctitis was associated with successful bowel restoration after temporary FD in contemporary studies. In the biologic era, temporary FD for refractory perianal and/or distal colonic CD improves symptoms in half the patients, and bowel continuity can be successfully restored in a quarter of patients.

Laparoscopic reversal of Hartmann’s procedure: a hospital-based prospective observational study

Background: Hartmann’s procedure involves surgical resection of the rectosigmoid colon with the closure of the anorectal stump and the formation of an end colostomy. After recovery from the initial surgery, colostomy reversal and restoration of bowel continuity are indicated in selected patients. The second stage procedure is associated with a considerable morbidity rate of 10% to 50% and a modest but genuine fatality rate. Laparoscopic reversal of Hartmann’s procedure is a safe and practical alternative to the open reversal method. Methods: This prospective observational study was conducted in the department of general surgery, GMC Srinagar over a period of 2 years after obtaining ethical clearance from the institutional ethical committee. Results: Our study included 40 patients between the age group of 32 to 67 years, with the highest incidence between 41 to 50 years. 32 males and 8 females with a ratio of 4:1. Mean operative time was 184.6±47.06 minutes. The conversion rate to open was 10%. The mean duration of hospital stay was 6.25±2.21 days. The mean time of return to normal work was 13.4 days. Postoperatively, two patients developed ileus which was managed in the immediate postoperative period and two suffered from adhesion obstruction, managed by diagnostic laparoscopy with adhesiolysis. It remained uneventful in the rest of the patients. Conclusions: Laparoscopic reversal of Hartmann’s procedure is safe, effective, and achieves faster positive results with significantly better short-term outcomes despite a proportion of patients being converted to open surgery.

Surgical management of rectal foreign bodies: A single-center experience.

Rectal foreign bodies (RFBs) are one of the rare clinical presentations in colorectal surgical practice, with an increasing incidence over the recent years. Due to the lack of standardized treatment options, the management of RFBs can be chal-lenging. This study aimed to evaluate our diagnostic and therapeutic approach to RFBs and to suggest a management algorithm. All patients with RFBs who hospitalized between January 2010 and December 2020 were retrospectively reviewed. Patient demographics, RFB insertion mechanism, inserted objects, diagnostic findings, management, complications, and outcomes were all evaluated. An algorithm for clinical management was developed depending on the center's experience. The cohort consisted of 21 patients, 17 (81%) were males. The median age was 33 years (ranging, 19-71). Sexual prefer-ences were the reason for RFB in 15 (71.4%) patients. In 17 (81%) patients, the RFB size over 10 cm. In 4 (19%) patients, RFBs were removed transanally without anesthesia in the emergency department; in the remaining 17 (81%), they were removed under anesthesia. Among these, RFBs were removed transanally under general anesthesia in 2 (9.5%) patients; with the assistance of a colonoscope under anesthesia in 8 (38%) patients; by milking towards the transanal route during laparotomy in 3 (14.2%) patients; and with the Hartmann procedure without restoration of bowel continuity in 4 (19%) patients. The median hospital stay was 6 days (ranging, 1-34 days). The Clavien-Dindo grade III-IV complication rate was 9.5%, and no post-operative mortality was observed. RFBs can usually be successfully removed transanally in the operating room with appropriate anesthetic technique and proper surgical instrument selection.

Minimally invasive surgery inolder children with Hirschsprung's disease in a North African Country.

Hirschsprung's disease (HSD) is a bowel congenital anomaly affecting mainly the enteric nervous system of the rectosigmoid region. Surgical resection of the aganglionic segment and restoration of bowel continuity via coloanal anastomosis is the main stay of treatment. In 1999, Georgeson et al. introduced a new minimally invasive approach as a standard for the pull-through mechanism. This study aims to evaluate the safety and possibility of the use of a laparoscope in older children with HSD with various techniques for HSD surgery. This study was performed based on 20 patients diagnosed with HSD. The patients are older children, whose mean age is 3 years. The cases showing enterocolitis or obstruction were excluded from the study. We divided these cases into two groups: Group A, consisting of 10 cases where laparoscopic-aided transanal pull-through was done, and group B, in which the laparoscopic Duhamel procedure was done. We compared between two groups for the first year follow-up period. In Group A, there were two cases of stenosis that respond to regular dilation: one case of enterocolitis and one case of fecal incontinence. In Group B, we had two cases of constipation and three cases of enterocolitis. There was no anastomotic leak in both groups. Minimally invasive surgery is safe in management of HSD in older children in one stage, either by using the Duhamel or transanal Swenson procedure.

Deloyers procedure compared to ileorectal anastomosis as restoration techniques of bowel continuity after extended left colon resection.

Restoration of bowel continuity after left extended colectomy may be challenging because the remaining colon may not reach the rectal stump without tension to perform a safe anastomosis. Performing a total colectomy with ileorectal anastomosis (IRA) is an option, but the quality of life can be significantly impaired due to loose stools and an increase in bowel frequency. In contrast, the preservation of the right colon and ileocaecal valve in the Deloyers procedure (DP) might ensure a better stool consistency and bowel transit, and therefore a superior quality of life. A transverse study comparing patients that underwent DP versus patients with an IRA was performed. Postoperative morbidity, mortality, functional outcomes, and quality of life were analysed between groups. Quality of life after the surgical procedure was assessed with the SF-36 V2® health survey. A total of 16 patients with DP and 32 with IRA were included. The groups had similar demographic characteristics concerning age, sex, body mass index, ASA classification, diagnosis and Charlson comorbidity index. The median follow-up was 55 months for DP and 99 months for IRA. Postoperative complications were similar in both groups. Patients in the DP group had fewer bowel movements (P=0.01), tenesmus (P=0.04) and use of loperamide (P=0.03). DP patients achieved better scores in physical pain (P=0.02) and general health (P < 0.01) than IRA patients. DP for intestinal continuity restoration after extended left colon resection is a safe and feasible alternative, possibly achieving better functional outcomes and quality-of-life compared to IRA.

Single center experience with salvage surgery for chronic pelvic sepsis.

Chronic pelvic sepsis eventually requires salvage surgery in half of all patients. The goal of surgery is to resolve pelvic inflammation while restoring intestinal continuity. Our salvage procedure achieves this by bringing a healthy conduit into the pelvis and creating an anastomosis beyond the source of sepsis. We aimed to review our single center experience with this procedure for the treatment of chronic pelvic sepsis. All patients requiring the procedure from 2010 to 2018 were retrospectively reviewed using a prospective database. Morbidity and mortality were evaluated, and restoration of bowel continuity at 1-year rate was the endpoint. Twenty patients were included. The main indication was pelvic sepsis after anastomotic leak(AL). The median age was 60 (42-86) years and the median BMI was 26 (18-37)kg/m2. The median time carrying a stoma before the intervention was 15months, and median time to intervention was 32months. All patients had a diverting stoma. There were no death and overall morbidity reached 60%, and AL rate was 10%. At 1 year, 70% of the patients had their intestinal continuity restored. In expert hands, salvage surgery for chronic pelvic sepsis has acceptable morbidity rates, an acceptable rate of AL, and a bowel restoration success rate 70% at 1 year, and is a valuable option for patients failing conservative treatment.

Intracorporeal or extracorporeal ileocolic anastomosis after laparoscopic right colectomy: cost analysis of the Torino trial.

Intracorporeal (IIA) and extracorporeal anastomosis (EIA) are two well-established techniques for restoration of bowel continuity after laparoscopic right colectomy (LRC). Since no economic analysis comparing the two different anastomotic techniques has been performed yet, it is still unclear if IIA can reduce perioperative costs. The aim of the study was to compare costs of LRC with IIA or EIA for right-sided colon neoplasm. This is a cost analysis of a single-institution double-blinded randomized controlled trial comparing the outcomes of LRC with IIA and LRC with EIA in patients with a right-sided colon neoplasm. All direct in-hospital costs related to patient's admission were recorded (intraoperative costs: operative room, surgical tools, blood units-postoperative costs: hospital stay, laboratory and microbiology analyses, diagnostic services, analgesic drugs and antibiotic therapy, blood units, reoperation-outpatient costs: post-discharge wound medications). This trial was registered with ClinicalTrials.gov, Number NCT03045107. A total of 140 patients were randomized and analyzed. Mean overall costs in the IIA group exceeded 349€ the mean overall costs of the EIA group (7926.87 ± 4617.23€ vs. 7577.45 ± 6131.17€; P = 0.704). A mean extra charge of 608€ regarding total intraoperative costs was recorded in the IIA group (3058.84 ± 897.42€ vs. 2450.15 ± 558.90€; P < 0.001). The cost of surgical instruments resulted in 542€ additional charge per patient in the IIA group compared to EIA group (1782.74 ± 541.26€ vs. 1240.55 ± 384.09€; P < 0.001). The mean cost of operative room occupancy was comparable in IIA and EIA group: 1276.09 ± 514.94€ vs. 1209.60 ± 422.80€ (P = 0.405). No significant differences were observed in postoperative costs and in outpatient costs. This economic analysis showed that IIA and EIA after LRC had similar overall costs, even though there were intraoperative extra costs of IIA.

Colostomy Reversal following Hartmann's Procedure: The Importance of Timing in Short- and Long-Term Complications: A Retrospective Multicentric Study.

The restoration of bowel continuity following Hartmann’s Procedure (HP) has been reported hitherto with high morbidity and mortality rates. No clear guidelines exist about timing in Hartmann’s Reversal (HR), the literature data being conflicting. We have sought to investigate the effect of the interval time between HP and HR in short- and long-term HR outcomes through a retrospective study based on consecutive patients undergoing HR between 2009 and 2017 in two regional hospitals in Italy. Demographic characteristics, comorbidities, intra- and post-operative data, as well as early complications, were recorded. Long-term data were collected on the surgical site occurrences of Incisional Ventral Hernia (IVH). One hundred and five patients were recruited for the study. Late HR, female gender, and long operating time were related to the highest incidence of peri-operative complications. Patients who developed IVH had undergone HR at significantly shorter times and had a higher Body Mass Index (BMI). The timing of HR seems to be an important variable linked to the onset of early and late post-operative complications. The patients submitted to early HR show a significantly lower complication rate but, at the same time, a higher rate of IVH incidence after restorative surgery. These data, in our opinion, reflect the need for planning, where possible, an early restoration of bowel continuity after HP.

Postoperative results and complications of fecal diversion for anorectal Crohn’s disease

PurposeFecal diversion is a less-invasive technique that can alleviate symptoms in patients with refractory anorectal Crohn’s disease. However, complications, including recurrence of residual anorectal Crohn’s disease, may develop. We aimed to evaluate the postoperative results and complications associated with fecal diversion in patients with refractory anorectal Crohn’s disease.MethodsWe enrolled 1218 Crohn’s disease patients who underwent laparotomy at our institute. We retrospectively analyzed the clinical features of 174 patients who underwent fecal diversion for refractory anorectal Crohn’s disease, complications of the diverted colorectum, and the incidence and risk factors for proctectomy after fecal diversion.ResultsAfter fecal diversion, 74% of patients showed improved symptoms. However, bowel continuity restoration was successful in four patients (2.2%), and anorectal Crohn’s disease recurred in all patients. Seventeen patients developed cancer with a poor prognosis. The rate of conversion to proctectomy after fecal diversion was 41.3%, and the risk factors included rectal involvement (p = 0.02), loop-type stoma (p < 0.01), and the absence of treatment with biologics after fecal diversion (p = 0.03).ConclusionFecal diversion for refractory anorectal Crohn’s disease can improve clinical symptoms. Patients with rectal involvement or loop-type stoma have a greater risk of requiring proctectomy following fecal diversion. The administration of biologic may decrease the rate of proctectomy.

Ileo-rectal anastomosis in ulcerative colitis-Long-term outcome, failure and risk of cancer at a tertiary centre.

Ileo-rectal anastomosis (IRA) is an option to restore bowel continuity after colectomy in patients with ulcerative colitis (UC). Concerns that the remaining rectum may serve as a site for continuing proctitis with subsequent poor function and IRA failure and the fear of development of dysplasia and cancer have led to the abandonment of IRA in large parts of the world. This study investigated the outcome of IRA in a large patient cohort with UC and IRA with regard to failure of IRA and development of dysplasia and cancer. This was a retrospective data gathering of patients with UC and IRA enrolled at the Department of Colorectal Surgery, Surgical Clinic, Sahlgrenska University Hospital/Östra, Gothenburg, 1972-2019. End-points were IRA failure, rectal dysplasia and cancer. IRA survival analysis and the cumulative probability of rectal cancer were calculated. In total, 183 patients (121 men) were included in the study. The IRA failure rate was 34% and the estimated cumulative IRA failure rates were 25% and 35% at 5 and 10 years respectively. Four patients developed rectal cancer and the estimated cumulative probability of rectal cancer was 3% and 6% at 10 and 15 years respectively. Ileo-rectal anastomosis remains a restorative option after colectomy for UC, even if the failure rate raises some concern. Further knowledge is needed for optimal patient selection to avoid early IRA failures. With increasing probability of rectal cancer over time a vigilant surveillance protocol is mandatory.

Bowel recovery after intra- vs extra-corporeal anastomosis for oncologic laparoscopic right hemicolectomy within an ERAS protocol: a retrospective study.

Restoring bowel continuity after laparoscopic right hemicolectomy with an intra-corporeal (IC) rather than an extra-corporeal (EC) ileocolic anastomosis may offer advantages in post-operative recovery. The aim of this study was to compare bowel function recovery between these two techniques, in a context of complete mesocolic excision within an enhanced recovery after surgery (ERAS) protocol. All consecutive patients who underwent oncologic laparoscopic right hemicolectomy from January 2012 to February 2021 in our institution were included in the study. Data were gathered from the prospectively maintained official ERAS (EIAS) database and completed through our institution's electronic health records. The primary endpoint was prolonged post-operative ileus (PPOI), defined as the need to insert a nasogastric tube, or refractory nausea VAS > 4, on or after the third post-operative day. Secondary endpoints were post-operative pain, morbidity and length of hospital stay (LoS). Groups were compared before and after propensity score matching based on age, gender, ASA score, use of epidural analgesia and post-operative complications. A total of 108 patients met the inclusion criteria, 36 (30%) had IC and 72 (70%) EC anastomosis. In the unmatched population, baseline characteristics were similar except for more frequent use of epidural analgesia in the EC group (62 (72.9%) vs. 17 (47.2), p = 0.007). PSM analysis was carried out. Operative time was longer in the IC group (197min (176-223) vs. 160 (140-189), p < 0.001). The rate of PPOI was similar (2 (5.6%) patients in the IC group vs. 10 (11.6%) in the EC group (p = 0.306)), but time to frist passage of flatus and stool was shorter in the IC group. There was no difference in morbidity but patients after IC anastomosis had lower pain VAS scores at 24h (p = 0.004) and a trend for a shorter LoS (6 (5-8) days vs 7 (5-10) in the EC group, p = 0.054). After PSM, there were 36 patients in each group. PPOI, time to first flatus and stool, morbidity and LoS were not significantly different although there was a trend for better recovery outcomes in the IC group. Patients in the IC group had significantly longer operative times but less pain at 24h. Although IC anastomosis was not significantly associated to lower rates of PPOI, it showed trends of faster recovery and significantly less post-operative pain at the expense of longer operating times.
