Primary Versus Staged Reconstruction and Risk of Surgical Failure in Patients With Ulcerative Colitis: a Nation-wide Cohort Study

BACKGROUND

Restorative surgery after colectomy due to ulcerative colitis (UC) may be performed simultaneously with colectomy (primary) or as a staged procedure. Risk factors for failure after restorative surgery are not fully explored. This study aimed to compare the risk of failure after primary and staged reconstruction.

METHODS

This is a national register-based cohort study of all patients 15 to 69 years old in Sweden treated with colectomy due to UC and who received an ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) between 1997 and 2017. Failure was defined as a reoperation with new ileostomy after restorative surgery or a remaining defunctioning ileostomy after 2 years. Risk of failure was calculated using the Kaplan-Meier method and Cox regression adjusted for sex, age, calendar period, primary sclerosing cholangitis, and duration of UC.

RESULTS

Of 2172 included patients, 843 (38.8%) underwent primary reconstruction, and 1329 (61.2%) staged reconstruction. Staged reconstruction was associated with a decreased risk of failure compared with primary reconstruction (hazard ratio, 0.73; 95% CI, 0.58-0.91). The 10-year cumulative risk of failure was 15% vs 20% after staged and primary reconstruction, respectively. In all, 1141 patients (52.5%) received an IPAA and 1031 (47.5%) an IRA. In stratified multivariable models, staged reconstruction was more successful than primary reconstruction in both IRA (hazard ratio, 0.75; 95% CI, 0.54-1.04) and IPAA (hazard ratio, 0.73; 95% CI, 0.52-1.01), although risk estimates failed to attain statistical significance.

CONCLUSIONS

In UC patients undergoing colectomy, postponing restorative surgery may decrease the risk of failure.

Is it safe to perform an anastomosis for rectal cancer after prostate cancer? A multicentre study of 126 patients from the GRECCAR group

AIM

To determine the safety of performing an anastomosis after rectal cancer (RC) resection in patients with a previously treated prostate cancer (PC).

METHODS

Patients with a previously treated PC who underwent rectal resection from 2008 to 2018 were retrospectively included. Outcomes were compared between patients who underwent rectal resection with anastomosis (restorative surgery, RS+ group) and those with a definitive stoma (RS- group). In the RS+ group, anastomotic leak (AL) rates were assessed according to the type of reconstruction.

RESULTS

A total of 126 patients underwent rectal surgery for mid-low RC after a previous PC treated by radiotherapy (RT) and/or radical prostatectomy. Overall, 80 patients (63%) underwent a RS and 46 patients (37%) underwent rectal surgery with a definitive stoma. There was no statistical difference between the two groups in terms of intraoperative data, except for the type of resection with more multivisceral resection in the RS- group (p < 0.01). In the RS+group, a diverting stoma was performed in 74% of cases. No difference between the two groups in terms of overall morbidity was found. In the RS+group (n = 80), 17 patients (21%) experienced AL. Of these, none was observed when delayed coloanal anastomosis was performed (p = 0.16). Long-term permanent stoma in the RS+ group was 16% (n = 13).

CONCLUSION

Restorative surgery after resection for RC in patients with a previous history of RT and/or radical prostatectomy for PC is safe without additional morbidity. In selected patients for restorative surgery, performing delayed coloanal anastomosis may represent a promising option.

Fournier's gangrene: its management remains a challenge

Fournier's gangrene (FG) is a rapidly progressive necrotizing bacterial dermo-hypodermitis of the perineum and external genitalia. It represents a real medical and surgical emergency requiring multidisciplinary care. Our study was based on the retrospective analysis of 18 cases of FG, collected in the Department of General and Visceral Surgery of Fattouma Bourguiba University Hospital in Monastir over an 18-year period extending from January 2000 to December 2018. Our series included 18 cases of FG collected over an 18-year period, an annual incidence of one case per year. The average age of our patients was 58 years (36 to 77). The male prevalence was clear. Diabetes and old age were found to be the major risk factors. The treatment was based on an aggressive surgical debridement remains to be the cornerstone of therapy and is commonly preceded by patient preparation for the surgical act by perioperative resuscitation and broad-spectrum antibiotic therapy, possibly accompanied by hyperbaric oxygen therapy (HBOT). The vaccum assisted closure (VAC) therapy is also used, which is a non-invasive system that promotes open wound healing. Healing techniques can be once the septic risk is controlled. Dressings topical treatments, such as fatty substances or calcium alginate, in addition to skin grafts, musculo-neurotic or musculo-cutaneous cover flaps can be used. During the follow-up period, no reccurrence occurred in 14 out of the 18 cases (2 patients were lost to follow-up and 2 patients died). A colostomy was closed in 10 out of 11 cases with simple follow-ups. Restorative surgery (partial thickness skin graft) at the perineal level was performed in only one case. Despite the better understanding of its etiopathogenesis, the advent of targeted antibiotic therapy, the establishment of a better codification of surgical procedures, the contribution of hyperbaric oxygenation and reconstruction techniques, mortality rates are still high and FG remains a real health threat, thus constituting a real medical and surgical emergency.

Restorative procedures in colonic crohn disease

Surgical management for refractory Crohn colitis often involves creation of a temporary or permanent stoma. Traditionally, the procedure of choice has been a total proctocolectomy with permanent ileostomy. However, restorative procedures that help to avoid a permanent stoma are being used with more frequency. In this article, the authors will address these procedures, including colocolonic anastomosis, ileorectal anastomosis, ileal pouch rectal anastomosis, and ileal pouch anal anastomosis. Factors that may influence one's decision to perform these procedures, such as patient age and nutritional status, medical comorbidities, sphincter function, desire to avoid a permanent ostomy, and prior medical therapy, will be discussed. Functional outcomes regarding these procedures will also be described. One should keep in mind that surgery does not cure Crohn disease and that postoperative long-term management is essential in preventing progression or recurrence of disease.

Sphincter-sparing surgery after preoperative radiotherapy for low rectal cancers: feasibility, oncologic results and quality of life outcomes

The present study assesses the choice of surgical procedure, oncologic results and quality of life (QOL) outcomes in a retrospective cohort of 53 patients with low-lying rectal cancers (within 6 cm of the anal verge) treated surgically following preoperative radiotherapy (RT, median dose 45Gy) with or without concomitant 5-fluorouracil. QOL was assessed in 23 patients by using two questionnaires developed by the QOL Study Group of the European Organization for Research and Treatment of Cancer: EORTC QLQ-C30 and EORTC QLQ-CR38. After a median interval of 29 days from completion of RT, abdominoperineal resection (APR) was performed in 29 patients (55%), low anterior resection in 23 patients (20 with coloanal anastomosis) and transrectal excision in one patient. The 3-year actuarial overall survival and locoregional control rates were 71.4% and 77.5% respectively, with no differences observed between patients operated by APR or restorative procedures. For all scales of EORTC QLQ-C30 and EORTC QLQ-CR38, no significant differences in median scores were observed between the two surgical groups. Although patients having had APR tended to report a lower body image score (P = 0.12) and more sexual dysfunction in male patients, all APR patients tended to report better physical function, future perspective and global QOL. In conclusion, sphincter-sparing surgery after preoperative RT seems to be feasible, in routine practice, in a significant proportion of low rectal cancers without compromising the oncologic results. However, prospective studies are mandatory to confirm this finding and to clarify the putative QOL advantages of sphincter-conserving approaches.
