Ileostomy reversal with handsewn techniques. Short-term outcomes in a teaching hospital

Short-term outcome of diverting loop ileostomy reversals performed by residents: a retrospective cohort prognostic factor study

AIM

The reversal of diverting loop ileostomy (DLI) is one of surgical trainees' first procedures. Complications of DLI reversal can cause life-threatening complications and increase patient morbidity. This study compared DLI reversals performed by surgical trainees with those by attending surgeons.

METHOD

This retrospective cohort study was performed at a single primary care center on 300 patients undergoing DLI reversal. The primary outcome was morbidity, according to the Clavien-Dindo classification (CDC), with special attention paid to the surgeon's level of training. The secondary endpoint was postoperative intestinal motility dysfunction.

RESULTS

Surgical trainees had significantly longer operation times (p < 0.001) than attending surgeons. Univariate analyses revealed no influence on the level of training for postoperative morbidity. First bowel movement later than 3 days after surgery was a significant risk factor for CDC [Formula: see text] 3 (OR, 4.348; 96% CI, 1670-11.321; p = 0.003). Independent risk factors for surgical site infections (SSIs) were an elevated BMI (OR, 1.162; 95% CI, 1.043-1.1294; p = 0.007) and a delayed bowel movement (OR, 3.973; 95% CI, 1.300-12.138; p = 0.015). For postoperative intestinal motility dysfunction, an independent risk factor was a primary malignant disease (OR, 1.980; 95% CI, 1.120-3.500; p = 0.019), and side-to-side stapled anastomosis was a protective factor (OR, 0.337; 95% CI 0.155-0.733; p = 0.006).

CONCLUSION

Even though surgical trainees needed significantly more time to perform the surgery, the level of surgical training was not a risk factor for increased postoperative morbidity. Instead, delayed first bowel movement was predictive of SSI.

Hand-sewn direct repair versus resection and hand-sewn anastomosis techniques for the reversal of diverting loop ileostomy after lower anterior rectal resection surgery: A randomized clinical trial

INTRODUCTION

Several techniques have been proposed for the closure of loop ileostomy. This is the first study comparing bowel function and outcomes of two different hand-sewn surgical techniques used for the closure of diverting protective loop ileostomy.

METHOD

In this prospective, randomized, double-blind clinical trial, 40 patients with a history of rectal cancer, low anterior resection, and diverting loop ileostomy who were candidates for ileostomy reversal were included and randomly assigned into two groups, hand-sewn direct repair of the ileal defect (group A) and resection and hand-sewn anastomosis of the ileum (group B).

RESULTS

The mean age of patients was 56.42 and 52.10 years in groups A and B, respectively. Regarding early postoperative period, group A developed earlier first gas passage (1.68 vs. 2.25 days, p = 0.041) and stool passage (2.10 vs. 2.80 days, p = 0.032). Group A also revealed shorter operating time (83.68 vs. 89.50 min, p = 0.040) and hospital stay (4.73 vs. 6.80 days, p = 0.001). None of the participants in both groups developed signs of bowel obstruction during the early and late postoperative follow-up period.

CONCLUSIONS

Direct hand-sewn repair for the closure of diverting loop ileostomy is a safe technique with better postoperative bowel function, oral diet tolerance, and less hospital stay compared to resection and hand-sewn anastomosis of the ileum.

Oncological Outcomes and Quality of Life After Rectal Cancer Surgery

Surgery for rectal cancer has been completely revolutionized thanks to the adoption of new technologies and up-to-date surgical procedures that have been applied to the traditional milestone represented by Total Mesorectal Excision (TME).

The multimodal and multidisciplinary approach, with new technologies increased the patients’ life expectancies; nevertheless, they have placed the surgeon in front of newer issues, represented by both oncological outcomes and the patients’ need of a less destructive surgery and improved quality of life.

In this review we will go through laparoscopic, robotic and transanal TME surgery, to show how the correct choice of the most appropriate technique, together with a deep knowledge of oncological principles and pelvic anatomy, is crucial to pursue an optimal cancer treatment. Novel technologies might also help to decrease the patients’ fear of surgery and address important issues such as cosmesis and improved preservation of postoperative functionality.

Incidence and predictors of postoperative ileus after loop ileostomy closure: a systematic review and meta-analysis

INTRODUCTION

Postoperative ileus (POI) is regarded as the most clinically significant morbidity following loop ileostomy closure; however, its incidence remains poorly understood. Our objective was therefore to determine the pooled incidence of POI after loop ileostomy closure and identify risk factors associated with its development.

METHODS

We systematically searched MEDLINE (via Ovid and PubMed), Embase, the Cochrane Library, Biosis Previews, and Scopus to identify studies reporting the incidence of POI in patients who underwent loop ileostomy closure. Two independent reviewers extracted data and appraised study quality. Cumulative incidence proportions were pooled across studies using a random-effects meta-analytic model.

RESULTS

Sixty-seven studies, including 9528 patients, met our inclusion criteria. The pooled estimate of POI was 8.0% (95% CI 6.9-9.3%; I² = 74%). The estimated incidence varied by POI definition: studies with a robust definition of POI (n = 8) demonstrated the highest estimate of POI (12.4%, 95% CI 9.2-16.5%; I² = 79%) while studies that did not report an explicit POI definition (n = 38) demonstrated the lowest estimate (6.7%, 95% CI 5.3-8.3%; I² = 61%). Small bowel anastomosis technique (hand-sewn) and interval time from ileostomy creation to closure (longer time) were the factors most commonly associated with POI after loop ileostomy closure. However, most comparative studies were not powered to examine risk factors for POI.

CONCLUSIONS

POI is an important complication after loop ileostomy closure, and its incidence is dependent on its definition. More research aimed at studying this complication is required to better understand risk factors for POI after loop ileostomy closure.

Impact of surgical proficiency levels on postoperative morbidity: a single centre analysis of 558 ileostomy reversals

PURPOSE

Defunctioning ileostomies reduce the consequences of distal anastomotic leakage following bowel resections. Ileostomy reversal in itself, however, is associated with appreciable morbidity (3-40%) and mortality (0-4%). Despite being a common teaching procedure, there is limited information on the impact of surgical proficiency levels on postoperative outcome.

METHODS

Adult patients undergoing closure of a defunctioning ileostomy between September 2008 and January 2017 were identified from a surgical administrative database that was collected prospectively (n = 558). Baseline characteristics (age, ASA score, BMI, health care insurance coverage) and closure techniques were recorded. Operation time, rate of bowel resection, postoperative complications ranked by Clavien-Dindo classification and length of stay were analysed with respect to proficiency levels (residents vs. consultants).

RESULTS

Two hundred three ileostomy reversals were performed by residents; 355 ileostomies were closed by consultants. Operation time was considerably shorter in the consultant group (p < 0.001). Major postoperative complication rates however were not different among the groups when adjusted for possible confounders (p = 0.948). The rate of anastomotic leakage was 3% and the overall major morbidity rate was 11%.

CONCLUSION

Operation time rather than surgical outcome and overall morbidity were affected by surgical proficiency levels. Therefore, ileostomy reversal can be considered an appropriate teaching operation for young general surgery trainees.
