Which factors influence the decision to perform Hartmann's reversal in various causative disease situations? A retrospective cohort study between 2006 and 2021

Surgical trends and outcomes of open, laparoscopic, and robotic colostomy reversal for benign disease

BACKGROUND

Despite the increasing use of minimally invasive surgeries, the outcome benefits of adopting minimally invasive surgery for colostomy reversal remain unclear. We aimed to analyze nationwide trends in the use of minimally invasive surgery for colostomy reversal and compare patient outcomes between different surgical approaches.

METHODS

The National Inpatient Sample was queried for patients who underwent colostomy reversal for benign disease from 2015 to 2021. National trends in the use of minimally invasive surgery for colostomy reversal were analyzed by Cochran-Armitage tests. Multivariable linear and logistic regressions accounting for hospital sample weights were developed to examine the association between operative approach (open, laparoscopic, and robotic) and patient outcomes, including hospital complications, length of stay, and hospital charges.

RESULTS

A total of 23,260 patients underwent colostomy reversal: 18,880 (81.2%) open, 3,245 (14.0%) laparoscopic, and 1,135 (4.9%) robotic surgery. From 2015 to 2021, the proportion of robotic approaches increased >5-fold (range 2.1-12.5%; Ptrend < .001), whereas the increase in laparoscopic approaches was not significant (range 11.5-16.2%; Ptrend = .34). Multivariable analysis showed that the laparoscopic approach was associated with a lower incidence of pulmonary complications (adjusted odds ratio, 0.49; 95% confidence interval, 0.28-0.87), surgical-site infection (odds ratio, 0.37; 95% CI, 0.19-0.72), peritonitis/abdominal abscess (odds ratio, 0.45; 95% confidence interval, 0.26-0.78), and paralytic ileus (odds ratio, 0.67; 95% confidence interval, 0.48-0.92). The robotic approach was associated with a lower incidence of paralytic ileus (odds ratio, 0.58; 95% confidence interval, 0.33-0.99). Laparoscopic and robotic approaches were associated with 22.9% and 29.9% shorter length of stay, respectively. The robotic approach was associated with 33.0% greater hospital charge.

CONCLUSIONS

This study observed a significant trend toward the increased use of robotics in colostomy reversal and potential clinical benefits with minimally invasive surgery. Robotic colostomy reversal, along with laparoscopic approach, may provide better postoperative recovery compared with the open approach; however, the utility of robotic surgeries needs to be reevaluated in the future, given the limited clinical benefits despite greater hospital charges.

Pneumorrhachis Secondary to a Locally Advanced Rectal Cancer with Pre-Sacral Abscess-Case Report and Review

The occurrence of pneumorrhachis (PR), defined as the presence of air within the spinal canal, presents a complex clinical picture with diverse etiological factors. We report an exceedingly rare case of PR arising from locally advanced rectal cancer accompanied by a pre-sacral abscess. This report aims to enhance awareness and understanding of rare causes of PR within the medical community, particularly among surgeons engaged in emergency procedures. The patient survived the acute phase of the disease through multiple surgical interventions and admission to the intensive care unit, but succumbed to cardiovascular complications three weeks later. We also offer a brief review of the literature concerning PR originating from the colorectal lumen.

Rectal stump leakage: A neglected complication after Hartmann's procedure for colorectal cancer

BACKGROUND

Hartmann's procedure is widely used in large bowel obstruction caused by colorectal cancer. However, rectal stump leakage, one of its serious complications, has not been well investigated in the literature.

METHODS

Patients with colorectal cancer who underwent Hartmann's procedure between January 2015 and January 2022 were retrospectively assessed. Rectal stump leakage was diagnosed based on the clinical symptoms, nature of drainage fluid, and computed tomography characteristics. The patients were categorized into the following 2 groups: non-rectal stump leakage group and rectal stump leakage group. A multivariate logistic regression model was used to identify independent risk factors for rectal stump leakage.

RESULTS

The incidence rate of postoperative rectal stump leakage was 11.6% in our patients. Univariate analysis revealed that male sex, body mass index (underweight), and tumor location (below the peritoneal reflection) were risk factors for rectal stump leakage (P < .05). Multivariate regression analysis confirmed these 3 factors were independent risk factors for rectal stump leakage (P < .05). Computed tomography imaging characteristics of patients with rectal stump leakage usually included inflammatory exudate and edema of the rectal stump, fluid, or gas-containing abscess around the rectal stump. The computed tomography imaging characteristics of a gas-containing abscess around the rectal stump and an abdominal drainage tube advanced into the rectum via the rectal stump could confirm the diagnosis of rectal stump leakage. The incidence rate of small bowel obstruction in group 2 (69.2%) was significantly higher than that in group 1 (15.7%) (P = .000).

CONCLUSION

Male sex, body mass index (underweight), and tumor location (below the peritoneal reflection) were independent risk factors for rectal stump leakage after Hartmann's procedure. We suggested that rectal stump leakage be classified into inflammatory exudation and abscess stages on computed tomography imaging. Unexplained small bowel obstruction after Hartmann's procedure may be an important clue to the early diagnosis of rectal stump leakage.
