Importance of Estimated Blood Loss in Resource Utilization and Complications of Hysterectomy for Benign Indications

Factors Associated with Complications after Total Pharyngo-Laryngo-Esophagectomy and Free Jejunal Flap Reconstruction

INTRODUCTION

Free jejunal flap (FJF) reconstruction is a standard procedure for pharyngeal and cervical esophageal defects resulting from head and neck cancer resection. However, improvements in patients' quality of life after surgery require a further statistical approach.

METHODS

An observational, retrospective, multivariate analysis was designed to report the incidence of postoperative complications and their association with clinical factors in 101 patients who underwent total pharyngo-laryngo-esophagectomy and FJF reconstruction for head and neck cancer at a university hospital between January 2007 and December 2020.

RESULTS

Postoperative complications were observed in 69% of patients. In the reconstructive site, anastomotic leak, observed in 8% of patients was associated with vascular anastomosis in the external jugular vein system (age-adjusted odds ratio [OR]: 9.05, p = 0.044) and anastomotic stricture, observed in 11% of patients was associated with postoperative radiotherapy (age-adjusted OR: 12.60, p = 0.02). Cervical skin flap necrosis was the most common complication (34%) and was associated with vascular anastomosis on the right cervical side (age- and sex-adjusted OR: 4.00, p = 0.005).

CONCLUSION

Although FJF reconstruction is a useful procedure, 69% of patients suffer a postoperative complication. We suppose that anastomotic leak is related to the low blood flow resistance of the FJF and inadequate drainage of the external jugular venous system, and anastomotic stricture is related to the vulnerability of the intestinal tissue to radiation. Furthermore, we hypothesized that the location of the vascular anastomosis may affect the mesenteric location of the FJF and the dead space in the neck, leading to the development of cervical skin flap necrosis. These data contribute to increasing our knowledge about postoperative complications related to FJF reconstruction.

The Prevalence, Indications, Outcomes of the Most Common Major Gynecological Surgeries in Kazakhstan and Recommendations for Potential Improvements into Public Health and Clinical Practice: Analysis of the National Electronic Healthcare System (2014-2019)

OBJECTIVES

Major gynecological surgeries are indicated for the treatment of female genital pathologies. It is key to examine trends in gynecologic surgical procedures and updated recommendations by international gynecological societies to find opportunities for improvement of local guidelines. To date, a very limited number of reports have been published on the epidemiology of gynecological surgeries in Kazakhstan. Moreover, some local guidelines for gynecological conditions do not comply with the international recommendations. Thus, this study aims to investigate the prevalence, indications, and outcomes of the most common major gynecological surgeries by analyzing large-scale Kazakhstani healthcare data, and identifying possible opportunities for improvement of the local public health and clinical practice.

METHODS

A descriptive, population-based study among women who underwent a gynecological surgery in healthcare settings across the Republic of Kazakhstan during the period of 2014-2019 was performed. Data were collected from the Unified Nationwide Electronic Health System (UNEHS).

RESULTS

In total, 80,401 surgery cases were identified and analyzed in the UNEHS database for a period of 6 years (2014-2019). The median age of the participants was 40 years old, with 61.1% in reproductive age. The most prevalent intervention was a unilateral salpingectomy-29.4%, with 72.6% patients aged between 18-34 years. The proportion of different types of hysterectomies was 49.4%. In 20% of cases, subtotal abdominal hysterectomy was performed due to uterine leiomyoma. The proportion of laparoscopic procedures in Kazakhstani gynecological practice is as low-11.59%.

CONCLUSIONS

The Kazakhstani public health and gynecological care sector should reinforce implementation of contemporary treatment methods and up-to-date policies and guidelines. The overall trends in surgical procedures performed for gynecological pathologies, including uterine leiomyoma and ectopic pregnancy treatment, should be changed in favor of the minimally invasive methods in order to adopt a fertility-sparing approach.

Vaginal vault drainage as an effective and feasible alternative in laparoscopic hysterectomy

Objective

Infected pelvic hematoma is a serious complication of hysterectomies. Pelvic drainage can help reduce complications. In this study, we evaluated the efficacy and safety of vaginal vault drainage in patients who underwent laparoscopic hysterectomy for benign gynecological diseases.

Methods

Patients who underwent laparoscopic hysterectomy and pelvic drain insertion for benign gynecological diseases between January 2008 and December 2015 were enrolled retrospectively in the study. They were grouped according to drain insertion sites, that is, through the abdomen (group 1) and vaginal vault (group 2). The postoperative outcomes were compared between the two groups.

Results

A total of 504 women were included. No significant differences were observed in the prevalence of postoperative fever, readmission, and reoperation between the two groups.

Conclusion

Given the discomfort associated with holding and removing the abdominal drain, inserting a closed pelvic gravity drain through the vaginal vault appears to be a feasible alternative to an abdominal drain.

Predictors of prolonged hospitalization and perioperative complications following mid-urethral sling mesh removal

PURPOSE

To assess preoperative and perioperative characteristics associated with increased length of stay and major complications after mid-urethral sling mesh removal.

METHODS

We performed an IRB-approved retrospective analysis of patients who underwent mid-urethral sling mesh removal. Demographic data and baseline surgical characteristics were collected. Operative reports and hospital/clinic notes were reviewed for complications which were categorized using the Clavien-Dindo Classification scheme. Length of stay was deemed abnormal if greater than 1 day. Complications were assessed using multivariate regression analysis.

RESULTS

A total of 468 patients were identified as having undergone mid-urethral sling mesh removal. Mean age was 56 (± 11.1). 431 patients had either retropubic or transobturator slings. 241 patients underwent retropubic or groin exploration as a part of their mesh removal. A prolonged length of stay was noted in 73 patients (15.6%) and 13 patients (2.8%) experienced a Clavien Grade 3 complication. Pre-operative narcotic/benzodiazepine use, concomitant surgical procedure, bladder injury, increased ASA class, and major complications had an increased odds of a prolonged length of stay. Patients who experienced a bladder injury, groin/suprapubic incision, and estimated blood loss of over 400 mL had an increased odds of Clavien Grade 3 complications.

CONCLUSIONS

Patient characteristics and perioperative factors are associated with increased length of stay and major complications after mid-urethral sling mesh removal.

Increased Intraoperative Faculty Entrustment and Resident Entrustability Does Not Compromise Patient Outcomes After General Surgery Procedures

BACKGROUND

Intraoperative resident autonomy has been compromised secondary to expectations for increased supervision without defined parameters for safe progressive independence, diffusion of training experience, and more to learn with less time. Surgical residents who are insufficiently entrusted during training attain less autonomy, confidence, and even clinical competency, potentially affecting future patient outcomes.

OBJECTIVE

To determine if OpTrust, an educational intervention for increasing intraoperative faculty entrustment and resident entrustability, negatively impacts patient outcomes after general surgery procedures.

METHODS

Surgical faculty and residents received OpTrust training and instruction to promote intraoperative faculty entrustment and resident entrustability. A post-intervention OpTrust cohort was compared to historical and pre-intervention OpTrust cohorts. Multivariable logistic and negative binomial regression was used to evaluate the impact of the OpTrust intervention and time on patient outcomes.

SETTING

Single tertiary academic center.

PARTICIPANTS

General surgery faculty and residents.

MAIN OUTCOMES AND MEASURES

Thirty-day postoperative outcomes, including mortality, any complication, reoperation, readmission, and length of stay.

RESULTS

A total of 8890 surgical procedures were included. After risk adjustment, overall patient outcomes were similar. Multivariable regression estimating the effect of the OpTrust intervention and time revealed similar patient outcomes with no increased risk (P > 0.05) of mortality {odds ratio (OR), 2.23 [95% confidence interval (CI), 0.87-5.6]}, any complication [OR, 0.98 (95% CI, 0.76-1.3)], reoperation [OR, 0.65 (95% CI, 0.42-1.0)], readmission [OR, 0.82 (95% CI, 0.57-1.2)], and length of stay [OR, 0.99 (95% CI, 0.86-1.1)] compared to the historic and pre-intervention OpTrust cohorts.

CONCLUSIONS

OpTrust, an educational intervention to increase faculty entrustment and resident entrustability, does not compromise postoperative patient outcomes. Integrating faculty and resident development to further enhance entrustment and entrustability through OpTrust may help facilitate increased resident autonomy within the safety net of surgical training without negatively impacting clinical outcomes.

Predictors of same-day discharge after minimally invasive hysterectomy for benign indications

OBJECTIVE

To identify predictors of same-day discharge after benign minimally invasive hysterectomy.

METHODS

In this retrospective cohort study, we identified women (n = 1084) undergoing benign minimally invasive hysterectomy from 2009 to 2016. Multivariate logistic regression was used to examine demographic, operative, and surgeon factors associated with discharge on postoperative day 0.

RESULTS

In our study population, 238 women (22%) were discharged on the same day. Robotic hysterectomy (risk ratio [RR] 2.24; 95% confidence interval [CI] 1.13-4.44), shorter operative time (lowest quartile; RR 5.28; 95% CI 2.66-10.46), and minimal blood loss (lowest quartile; RR 3.01; 95% CI 1.68-6.23) were associated with higher same-day discharge likelihood whereas later procedure start time (2-5 pm; RR 0.38; 95% CI 0.17-0.85) and postoperative complications (RR 0.19; 95% CI 0.06-0.55) significantly decreased its likelihood. The strongest predictor was surgeon's number of years in practice, with recently graduated surgeons more likely to discharge their patients on the same day (RR 3.15; 95% CI 2.09-4.77).

CONCLUSION

Same-day discharge after minimally invasive hysterectomy is determined by several patient, operative, and surgeon factors that can be incorporated into an implementation plan to promote earlier discharge. Most especially, scheduling patients based on perceived case complexity and targeted surgeon education can qualify a larger cohort for same-day discharge.

Single position circumferential fusion improves operative efficiency, reduces complications and length of stay compared with traditional circumferential fusion

BACKGROUND CONTEXT

Anterior lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion (LLIF) with percutaneous posterior screw fixation are two techniques used to address degenerative lumbar pathologies. Traditionally, these anterior-posterior (AP) surgeries involve repositioning the patient from the supine or lateral decubitus position to prone for posterior fixation. To reduce operative time (OpTime) and subsequent complications of prolonged anesthesia, single-position lumbar surgery (SPLS) is a novel, minimally invasive alternative performed entirely from the lateral decubitus position.

PURPOSE

Assess the perioperative safety and efficacy of single position AP lumbar fusion surgery (SPLS).

STUDY DESIGN

Multicenter retrospective cohort study.

PATIENT SAMPLE

Three hundred and ninety patients undergoing AP surgery were included, of which 237 underwent SPLS and 153 were in the Flip group.

OUTCOME MEASURES

Outcome measures included levels fused, percentage of cases including L5-S1 fusion, fluoroscopy radiation dosage, OpTime, estimated blood loss (EBL), length of stay (LOS), and perioperative complications. Radiographic analysis included lumbar lordosis (LL), pelvic incidence, pelvic tilt, and segmental LL.

METHODS

Patients undergoing primary ALIF and/or LLIF surgery with bilateral percutaneous pedicle screw fixation between L2-S1 were included over a 4-year period. Patients were classified as either traditional repositioned "Flip" surgery or SPLS. Outcome measures included levels fused, percentage of cases including L5-S1 fusion, fluoroscopy radiation dosage, OpTime, EBL, LOS, perioperative complications. Radiographic analysis included LL, pelvic incidence, pelvic tilt, and segmental LL. All measures were compared using independent samples t-tests and chi-squared analyses as appropriate with significance set at p < .05. Propensity matching was completed where demographic differences were found.

RESULTS

Three hundred and ninety patients undergoing AP surgery were included, of which 237 underwent SPLS and 153 were in the Flip group. Age, gender, BMI, and CCI were similar between groups. Levels fused (1.47 SPLS vs 1.52 Flip, p = .468) and percent cases including L5-S1 (31% SPLS, 35% Flip, p = .405) were similar between cohorts. SPLS significantly reduced OpTime (103 min vs 306 min, p < .001), EBL (97 vs 313 mL, p < .001), LOS (1.71 vs 4.12 days, p < .001), and fluoroscopy radiation dosage (32 vs 88 mGy, p < .001) compared to Flip. Perioperative complications were similar between cohorts with the exception of postoperative ileus, which was significantly lower in the SPLS group (0% vs 5%, p < .001). There was no significant difference in wound, vascular injury, neurological complications, or Venous Thrombotic Event. There was no significant difference found in 90-day return to operating room (OR).

CONCLUSIONS

SPLS improves operative efficiency in addition to reducing blood loss, LOS and ileus in this large cohort study, while maintaining safety.

Hysterectomy Complications Relative to HbA1c Levels: Identifying a Threshold for Surgical Planning

STUDY OBJECTIVE

To evaluate whether diabetes diagnosis and level of diabetes control as reflected by higher preoperative glycosylated hemoglobin (HbA_1c) levels are associated with increased complication rates after hysterectomy and to identify a threshold of preoperative HbA_1c level past which we should consider delaying surgery owing to increased risk of complications.

DESIGN

Retrospective cohort study.

SETTING

Hospitals in the Michigan Surgical Quality Collaborative between June 4, 2012, and October 17, 2017.

PATIENTS

Women with and without a diabetes diagnosis.

INTERVENTIONS

Hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Data on demographics, preoperative HbA_1c values, surgical approach, composite postoperative complications, readmissions, emergency department visits, and reoperations were abstracted. The risk of a postoperative complication when diabetes was stratified by preoperative HbA_1c level was evaluated in a sensitivity analysis, and independent associations were identified in a mixed, multivariate logistic regression model. We identified 41 286 hysterectomies performed at 70 hospitals to be included for analysis. The sensitivity analysis identified 4 groups of risk for postoperative complications: group 1: no diabetes diagnosis and no HbA_1c value; group 2: no diabetes diagnosis, with HbA_1c levels between 4% and 6.5%; group 3: diabetes diagnosis and no HbA_1c value or HbA_1c levels <9%; and group 4: diabetes diagnosis with HbA_1c levels ≥9%. In the adjusted model, there were significant 32% and 34% increased odds of postoperative complications for groups 2 and 3, respectively, compared with group 1. There were more than 2-fold increased odds of complications for women with diabetes and a preoperative HbA_1c level ≥9% (group 4) compared with the women in group 1. Diabetes diagnosis with preoperative HbA_1c levels ≥9% had increased odds of complications compared with diabetes diagnosis with preoperative HbA_1c levels <9%. Patients with well-controlled diabetes seemed to have increased odds of complications with laparoscopic surgery.

CONCLUSION

Diabetes diagnosis and measurement of preoperative HbA_1c levels provide risk stratification for postoperative complications after hysterectomy, with the highest observed effect among patients with diabetes with a preoperative HbA_1c level ≥9%.
