Outcomes of abdominoperineal resection for management of anal cancer in HIV-positive patients: a national case review

Urgent Focus on the Surgical Risks of People Living With HIV: A Systematic Review and Meta-Analysis

With the widespread promotion and application of antiretroviral therapy in clinical practice, people living with HIV (PLWH) have the potential to live as long as non-HIV people and the probability of surgery for PLWH has been increasing dramatically. However, the overall postoperative outcome and risk are still unclear. We performed comprehensive and methodical searches in PubMed, Embase, and Web of Science without date and language restrictions. Study outcomes included: (1) cure rate, (2) mortality, (3) reoperation rate, (4) incidence of any postoperative complications, (5) length of stay, and (6) operation duration. NOS scores were employed to evaluate bias risk, while publication bias was assessed using funnel plots and Egger tests. Review Manager version 5.4.1, R version 4.4.1, and Stata version 14.0 were employed to determine quantitative analysis, considering a significance level of p < 0.05. A total of 50 studies were included, involving 54 565 PLWH undergoing surgical treatment. Synthesis analysis showed that the mortality (OR = 1.70, 95% CI: 1.58-1.83, p < 0.00001), reoperation rate (OR = 1.78, 95% CI: 1.36-2.34, p < 0.00001), complication rate (OR = 1.56, 95% CI: 1.26-1.95, p < 0.00001), LOS (OR = 1.63, 95% CI: 1.28-1.99, p < 0.00001), and operation time (OR = 7.37, 95% CI: 1.14-13.59, p = 0.02) were increased in PLWH. However, there was no significant difference in the cure rate compared to the control group (OR = 1.27, 95% CI: 0.90-1.79, p = 0.18). Subgroup analysis showed that complication rates increased again in orthopedic (OR = 1.65, 95% CI: 1.34-2.05, p < 0.00001) and general surgery (OR = 1.72, 95% CI: 1.08-2.74, p = 0.02). However, the type of procedure, publication quality, study type, and patient origin were not sources of complication rate heterogeneity. Meta-regression showed that CD4 count had no effect on complication rate, but the anti-retroviral therapy rate had 34.89% explanatory power. There is an increased risk of postoperative death, reoperation, complications, and prolonged hospital stay and surgical duration in PLWH. However, conducting extensive prospective studies across multiple centers is crucial to validate these findings.

Increased Healthcare Utilization for Medical Comorbidities Prior to Surgery Improves Postoperative Outcomes

OBJECTIVE

The purpose of this study was to evaluate the impact of optimization of preoperative comorbidities by nonsurgical clinicians on short-term postoperative outcomes.

SUMMARY BACKGROUND DATA

Preoperative comorbidities can have substantial effects on operative risk and outcomes. The modifiability of these comorbidity-associated surgical risks remains poorly understood.

METHODS

We identified patients with a major comorbidity (eg, diabetes, heart failure) undergoing an elective colectomy in a multipayer national administrative database (2010-2014). Patients were included if they could be matched to a preoperative surgical clinic visit within 90 days of an operative intervention by the same surgeon. The explanatory variable of interest ("preoperative optimization") was defined by whether the patient was seen by an appropriate nonsurgical clinician between surgical consultation and subsequent surgery. We assessed the impact of an optimization visit on postoperative complications with use of propensity score matching and multilevel, multivariable logistic regression.

RESULTS

We identified 4531 colectomy patients with a major potentially modifiable comorbidity (propensity weighted and matched effective sample size: 6037). After matching, the group without an optimization visit had a higher rate of complications (34.6% versus 29.7%, P = 0.001). An optimization visit conferred a 31% reduction in the odds of a complication (P < 0.001) in an adjusted analysis. Median preoperative costs increased by $684 (P < 0.001) in the optimized group, and a complication increased total costs of care by $14,724 (P < 0.001).

CONCLUSIONS AND RELEVANCE

We demonstrated an association between use of nonsurgical clinician visits by comorbid patients prior to surgery and a significantly lower rate of complications. These findings support the prospective study of preoperative optimization as a potential mechanism for improving postoperative outcomes.

The financial burden of complications following rectal resection: A cohort study

To investigate the costs associated with postoperative complications following rectal resection.Rectal resection is a major surgical procedure that carries a significant risk of complications. The occurrence of complications following surgery has both health and financial consequences. There are very few studies that examine the incidence and severity of complications and their financial implications following rectal resection.We identified 381 consecutive patients who underwent a rectal resection within a major university hospital. Patients were included using the International Classification of Diseases (ICD) codes. Complications in the postoperative period were reported using the validated Clavien-Dindo classification system. Both the number and severity of complications were recorded. Activity-based costing methodology was used to report financial outcomes. Preoperative results were also recorded and assessed.A 76.9% [95% CI: 68.3:86.2] of patients experienced one or more complications. Patients who had a complication had a median total cost of $22,567 [IQR 16,607:33,641]. Patients who did not have a complication had a median total cost of $15,882 [IQR 12,971:19,861]. The adjusted additional median cost for patients who had a complication was $5308 [95% CI: 2938:7678] (P < .001). Patients who experienced a complication tended to undergo an open procedure (P = .001), were emergent patients (P = .003), preoperatively had lower albumin levels (36 vs 38, P = .0003) and were anemic (P = .001).Complications following rectal resection are common and are associated with increased costs. Our study highlights the importance of evaluating and preventing complications in the postoperative period.

Health costs of post-operative complications following rectal resection: a systematic review

BACKGROUND

Post-operative complications following rectal resection pose significant health and cost implications for patients and health providers. The objective of this study is to review the associated cost of complications following rectal resection. This included reporting on the proportion and severity of these complications, associated length of stay and surgical technique used. Studies were sourced from Embase OVID, MEDLINE OVID (ALL) and Cochrane Library databases by utilizing a search strategy.

METHODS

This search contained studies from 1 January 2010 until 13 February 2019. Studies were included from the year 2010 to account for the implementation of enhanced recovery after surgery protocols. Studies that reported the financial cost associated with complications were included. Any indication for rectal resection was considered. Data was extracted into a formatted table and a narrative synthesis was performed.

RESULTS

We identified 13 eligible studies for inclusion. There was strong evidence to suggest that complications are associated with increased costs. There was considerable variation as to the costs attributable to complications ($1443 (P < 0.001) to $17 831 (P < 0.0012), n = 12). The presence of complications was associated with an increased length of stay (5.54 (P-value not given) to 21.04 (P < 0.0001) days, n = 7). There was significant variation in the proportion of complications (6.41 to 64.71%, n = 8). Weak evidence existed around surgical technique used and the associated cost of complications. There was considerable heterogeneity among included studies.

CONCLUSIONS

Complications following rectal resection increased health costs. Costs should be standardized and provide a clear methodology for their calculation. Complications should be standardized and include a grading of severity.

The Effect of Human-Immunodeficiency Virus Status on Outcomes in Penetrating Abdominal Trauma: An Interim Analysis

BACKGROUND

The purpose of this study was to determine whether the outcomes of hemodynamically stable patients undergoing exploratory laparotomy for penetrating abdominal trauma differed as a result of their HIV status.

METHODS

This was an observational, prospective study from February 2016 to May 2017. All hemodynamically stable patients with penetrating abdominal trauma requiring a laparotomy were included. The mechanism of injury, the HIV status, age, the penetrating abdominal trauma index (PATI), and the revised trauma score (RTS) were entered into a binary logistic regression model. Outcome parameters were in-hospital death, morbidity, admission to intensive care unit (ICU), relaparotomy within 30 days, and length of stay longer than 30 days.

RESULTS

A total of 209 patients, 94% male, with a mean age of 29 ± 10 years were analysed. Twenty-eight patients (13%) were HIV positive. The two groups were comparable. Ten (4.8%) laparotomies were negative. There were two (0.96%) deaths, both in the HIV negative group. The complication rate was 34% (n = 72). Twenty-nine patients (14%) were admitted to the ICU. A higher PATI, older age, and a lower RTS were significant risk factors for ICU admission. After 30 days, 12 patients (5.7%) were still in hospital. Twenty-four patients (11%) underwent a second laparotomy. The PATI score was the single independent predictor for complications, relaparotomy, and hospital stay longer than 30 days.

CONCLUSIONS

Preliminary results reveal that HIV status does not influence outcomes in patients with penetrating abdominal trauma.

Early Surgical Intervention for Acute Ulcerative Colitis Is Associated with Improved Postoperative Outcomes

BACKGROUND

Timing of surgical intervention for acute ulcerative colitis has not been fully examined during the modern immunotherapy era. Although early surgical intervention is recommended, historical consensus for "early" ranges widely. The purpose of this study was to evaluate outcomes according to timing of urgent surgery for acute ulcerative colitis.

METHODS

All non-elective total colectomies in ulcerative colitis patients were identified in the National Inpatient Sample from 2002 to 2014. Procedures, comorbidities, diagnoses, and in-hospital outcomes were collected using International Classification of Disease, 9th Revision codes. An operation was defined as early if within 24 hours of admission. Results were compared between the early versus delayed surgery groups.

RESULTS

We found 69,936 patients that were admitted with ulcerative colitis, and 2650 patients that underwent non-elective total colectomy (3.8%). Early intervention was performed in 20.4% of patients who went to surgery. More early operations were performed laparoscopically (28.1% versus 23.3%, p = 0.021) and on more comorbid patients (Charlson Index, p = 0.008). Median total hospitalization costs were $20,948 with an early operation versus $33,666 with a delayed operation (p < 0.001). Delayed operation was an independent risk for a complication (OR = 1.46, p = 0.001). Increased hospitalization costs in the delayed surgery group were statistically significantly higher with a reported complication (OR = 3.00, p < 0.001) and lengths of stay (OR = 1.26, p < 0.001).

CONCLUSION

Delayed operations for acute ulcerative colitis are associated with increased postoperative complications, increased lengths of stay, and increased hospital costs. Further prospective studies could demonstrate that this association leads to improved outcomes with immediate surgical intervention for medically refractory ulcerative colitis.

Cervical cancer control in HIV-infected women: Past, present and future

Since the initial recognition of acquired immunodeficiency syndrome (AIDS) in 1981, an increased burden of cervical cancer was identified among human immunodeficiency virus (HIV)-positive women. Introduction of antiretroviral therapy (ART) decreased risks of opportunistic infections and improved overall survival. HIV-infected women are living longer. Introduction of the human papillomavirus (HPV) vaccine, cervical cancer screening and early diagnosis provide opportunities to reduce cervical cancer associated mortality. In line with 2030 Sustainable Development Goals to reduce mortality from non-communicable diseases, increased efforts need to focus on high burden countries within sub-Saharan Africa (SSA). Despite limitations of resources in SSA, opportunities exist to improve cancer control. This article reviews advancements in cervical cancer control in HIV-positive women.
