Management of vascular injuries on ICU patients: KZN experience

BACKGROUND

Vascular injury management remains an extremely challenging task. The fundamental principles of management are bleeding arrest and flow restoration, to avoid death and amputation. With advances in medicine, there has been a shift from ligation to primary repair which has resulted in a fall in amputation rate from 50 % in World War II to less than 2 % in civilian injuries.

METHOD

A retrospective cross-sectional study was conducted on ICU requiring polytrauma patients with vascular trauma admitted between January 2013 and December 2021. Additional data were collected prospectively from January 2022 to December 2022. All data was from an ethics approved Trauma Registry. The injury was either confirmed by imaging or via exploration. The pre-designed data proforma acquired the following variables: age, mechanism of injury, injured vessel, associated injury, management of the vessel, and management of the associated injury. The data were analysed using Stata version 17 (StataCorp, College Station TX). Frequencies and percentages were calculated to summarise numerical data An ethical clearance was granted by the University of KwaZulu-Natal BREC (BREC 0004353/2022) and the KZN Department of Health. All data were de-identified in the data collection sheet.

RESULTS

There were 154 arterial injuries and 39 venous injuries. The majority, 77 (50 %) of arterial injuries were managed via open strategies, and 36 (23 %) were managed via endovascular intervention. The majority, 20 (51 %) of venous injuries underwent open ligation, and 12 (31 %) were managed non-surgically. The highest number of endovascular interventions was observed in aortic injuries. For a total of 25 aortic injuries, 22 (83 %) were managed endovascular (TEVAR) and 2 (8 %) were managed non-operatively.

CONCLUSION

The choice between the endovascular and open approach depends on the injured blood vessel. The majority of venous injuries were treated with open ligation in this cohort.

Systematic review and meta-analysis of randomized controlled trials evaluating the effect of the level of ligation of inferior mesenteric artery on functional outcomes in rectal cancer surgery

BACKGROUND

This systematic review and meta-analysis studied the role of high (HL) versus low (LL) inferior mesenteric artery (IMA) ligation on genitourinary and defecatory dysfunction in patients who had undergone resection for rectal cancer (RC).

METHODS

A systematic literature search of four major databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Randomized controlled trials (RCTs) comparing HL and LL of IMA in RC surgery were identified. Those studies that looked at genitourinary or defecatory dysfunction were included. Random-effects modeling to summarize statistics was performed. The risk of bias was assessed using Cochrane's Risk-of-Bias tool 2.

RESULTS

Three RCTs were included. There was clinical heterogeneity with regard to cancer stage and location as well as operative techniques and adjuvant treatments. Functional outcomes (FO) that were reported by at least two studies were International Consultation on Incontinence Questionnaire (ICIQ), International Index for Erectile Function (IIEF), Jorge-Wexner incontinence score (J-W). Difference was observed in ICIQ at 9 months after surgery favoring LL (standard mean difference: - 0.66; 95% confidence intervals (CI): - 0.92, - 0.40; P = 0.37; I 2 = 0%). Difference was also observed in IIEF at 9 months favoring LL (mean difference: 7.43; CI: 1.86, 13.00; P = 0.16; I 2 = 50%).

CONCLUSIONS

Although our study has demonstrated the superiority of LL in genitourinary function preservation, these results should be taken with consciousness due to significant heterogeneity between included studies, small sample size, and potential bias. More high-quality studies are needed.

A prospective and comparative study between stapled hemorrhoidopexy and hemorrhoidal artery ligation with mucopexy

AIM

The aim of this study was to compare the efficacy between stapled hemorrhoidopexy (Longo technique) and transanal hemorrhoidal artery ligation with mucopexy (THDm) in the treatment of hemorrhoidal disease.

PATIENTS AND METHODS

From June 2009 to January 2011, 81 patients having grade II or III hemorrhoidal disease underwent prospective evaluation followed by surgery at two centers (27 Longo and 54 THDm). Symptoms (bleeding, tenesmus, prolapse, fecal incontinence, pain) and the satisfaction score were compared on the first post-operative day and at 1, 6, 12, and 24 months thereafter. The follow-up was 24 months.

RESULTS

There was no difference in mean length of stay. One complication (recto-vaginal fistula) was observed after Longo. The prolapse score was significantly lower after THDm than after Longo on the first post-operative day (P < 0.0015). Bleeding score after THDm was significantly lower on the first post-operative day (P = 0.04), but higher thereafter (P = 0.03 and P = 0.04). Tenesmus score after THDm was significantly lower for the first three months (P < 0.06 and 0.001). On the first post-operative day and at one month, the visual analog pain score was significantly lower after THDm than that after Longo (P < 0.0003 et P < 0.01). On the first post-operative day and at one month, the satisfaction score was higher after THDm than after Longo (P < 0.001).

CONCLUSION

THDm was safe and effective. Short-term outcomes after THDm were better than after Longo but long-term results seemed to be similar.
