Placement of Nasogastric Tubes in Pancreaticoduodenectomy Patients: Switching from Immediate Intraoperative Removal to Avoiding Unnecessary Perioperative Use

BACKGROUND

The placement of nasogastric tubes (NGTs) in abdominal surgery has been adopted for decades to attenuate ileus and prevent aspiration pneumonia. In the recent era, the guidelines recommend not using NGT routinely, and even in pancreaticoduodenectomy (PD), immediate removal of NGT in operating rooms (ORs) was suggested. However, the clinical outcome and safety of abandoning NGT during the pre-PD and intra-PD periods remain unknown.

METHODS

We conducted a single-center retrospective review on adult PD patients aged between 20 and 75 years from 2013 to 2022. The study population was grouped into the NGT group (NGT was placed before PD and immediately removed in the ORs) and the non-NGT group (NGT was not placed preoperatively). Safety was evaluated by the number of adverse events. The primary aim of this study is to evaluate the need of NGT insertion in ORs among PD patients.

RESULTS

The case numbers in the NGT and non-NGT groups were 391 and 578, respectively. No case in the non-NGT group needed the intraoperative insertion of NGT. The rate of pulmonary complications was 2.3% in the NGT group compared to 1.6% in the non-NGT group (P = 0.400). Furthermore, there were no significant differences in terms of rates of major complications (12.8% vs. 9.3%, P = 0.089) or mortality (1.0% vs. 1.0%, P =0.980) between the two groups. The rates of the postoperative insertion of NGT in the NGT and non-NGT groups were 2.6% and 2.8% (P = 0.840), respectively.

CONCLUSION

For selected PD patients, the placement of NGT during pre-PD and intra-PD periods may be safely omitted. This primary study is considered the first foundation stone in the extension of the element of no NGT in PD.

Relationship between the timing of chemotherapy and surgical complications following surgical biopsy in children with malignant solid tumors

BACKGROUND

Biopsies for diagnosis before chemotherapy is common in children with malignant solid tumors. Wound healing is delayed by chemotherapy; however, the ideal interval between biopsy and chemotherapy remains unknown. We aimed to summarize the relationship between chemotherapy timing and postoperative surgical complications.

PROCEDURE

We retrospectively reviewed patients with malignant solid tumors who underwent chemotherapy after surgical biopsy at our institution between January 2014 and August 2020. The primary outcomes were postoperative surgical complications (within 30 days) and the timing of chemotherapy.

RESULTS

Forty-three patients were analyzed. The types of tumors were neuroblastoma (n = 20), hepatoblastoma (n = 10), Ewing sarcoma (n = 5), germ cell tumor (n = 3), angiosarcoma (n = 1), clear cell sarcoma (n = 1), ganglioneuroblastoma (n = 1), rhabdoid tumor (n = 1), and rhabdomyosarcoma (n = 1). The operative procedures were thoracoscopy (n = 5), laparotomy (n = 17), laparoscopy (n = 14), and superficial (n = 7). The median time [range] to chemotherapy after biopsy was 4 [0-21] days. No surgical complications occurred before chemotherapy, and two (4.7%) patients experienced complications after chemotherapy. These included postoperative hemorrhage (grade 3) and surgical site infection (grade 1). Chemotherapy was initiated 1 and 6 days after biopsy, respectively, in these cases. Complications occurred 10 and 23 days after biopsy, respectively.

CONCLUSION

The rate of postoperative surgical complications related to biopsy seems acceptable, even when chemotherapy was initiated in the early postoperative period. Early initiation of chemotherapy after biopsy may be a suitable option, particularly in children with bulky or symptomatic malignant solid tumors.

Integration of a dedicated management protocol in the care of pediatric liver cancer: From specialized providers to complication reduction

INTRODUCTION

Up to a third of children undergoing partial hepatectomy for primary hepatic malignancies experience at least one perioperative complication, with a presumed deleterious effect on both short- and long-term outcomes. We implemented a multidisciplinary treatment protocol in the management of these patients in order to improve complication rates following partial hepatectomy.

METHODS

A retrospective chart review was completed for all patients < 18 years of age who underwent liver resection at our institution between 2002 and 2019 for primary hepatic cancer. Demographic, intraoperative, postoperative, pathologic, and outcome data were analyzed for perioperative complications using the CLASSIC and Clavien-Dindo (CD) scales, event-free survival (EFS) and overall survival (OS).

RESULTS

A total of 73 patients were included in the analysis with 33 prior-to and 40 after dedicated provider protocol implementation. Perioperative complication rates decreased from 52% to 20% (p = 0.005) with major complications going from 18% to 10% (p = 0.31). On multivariable logistic regression, protocol implementation was associated with a reduction in any (OR 0.29 [95% CI 0.09 - 0.89]) but not major complications. On multivariate cox models, post protocol implementation was associated with improved event free survival (EFS) (HR 0.19 (0.036 - 0.195). Among patients with a diagnosis of hepatoblastoma (n = 62), the occurrence of a major perioperative complication was associated with a worse EFS (HR=5.45, p = 0.03) on multivariate analysis, however this did not translate into an impact on overall survival.

CONCLUSIONS

Our results demonstrate that, for children with primary liver malignancies, a dedication of patients to high-volume surgeons can improve rates of complications of liver resections and may improve the oncological outcome of hepatoblastoma.

Negative pressure wound therapy versus conventional wound care in cancer surgical wounds: A meta-analysis of observational studies and randomised controlled trials

The application of negative pressure wound therapy (NPWT) in cancer surgical wounds is still controversial, despite its promising usage, because of the risks of increased tumorigenesis and metastasis. This study aimed to review the risks and benefits of NPWT in surgical wounds with the underlying malignant disease compared with conventional wound care (CWC). The first outcome was wound complications, divided into surgical site infection (SSI), seroma, hematoma, and wound dehiscence. The secondary outcome was hospital readmission. We performed a separate meta‐analysis of observational studies and randomised controlled trials (RCTs) with CI 95%. Thirteen observational studies with 1923 patients and seven RCTs with 1091 patients were included. NPWT group showed significant decrease in the risk of SSI (RR = 0.45) and seroma (RR = 0.61) in observational studies with P value <0.05, as well as RCTs but were not significant (RR = 0.88 and RR = 0.68). Wound dehiscence (RR = 0.74 and RR = 1.15) and hospital readmission (RR = 0.90 and RR = 0.62) showed lower risks in NPWT group but were not significant. Hematoma (RR = 1.08 and RR = 0.87) showed no significant difference. NPWT is not contraindicated in cancer surgical wounds and can be considered a beneficial palliative treatment to promote wound healing.

Risk Factors for 30-Day Unplanned Readmission After Hepatectomy: Analysis of 438 Pediatric Patients from the ACS-NSQIP-P Database

BACKGROUND

Hepatic resections are uncommon in children. Most studies reporting complications of these procedures and risk factors associated with unplanned readmissions are limited to retrospective data from single centers. We investigated risk factors for 30-day unplanned readmission after hepatectomy in children using the American College of Surgeons National Surgical Quality Improvement-Pediatric database.

METHODS

The database was queried for patients aged 0-18 years who underwent hepatectomy for the treatment of liver lesions from 2012 to 2018. Chi-squared tests were performed to evaluate for potential risk factors for unplanned readmissions. A multivariate regression analysis was performed to identify independent predictors for unplanned 30-day readmissions.

RESULTS

Among 438 children undergoing hepatectomy, 64 (14.6%) had unplanned readmissions. The median age of the hepatectomy cohort was 1 year (0-17); 55.5% were male. Patients readmitted had significantly higher rates of esophageal/gastric/intestinal disease (26.56% vs. 14.97%; p=0.022), current cancer (85.94% vs. 75.67%; p=0.012), and enteral and parenteral nutritional support (31.25% vs. 17.65%; p=0.011). Readmitted patients had significantly higher rates of perioperative blood transfusion (67.19% vs. 52.41%; p=0.028), organ/space surgical site infection (10.94% vs. 1.07%; p<.001), sepsis (15.63% vs. 3.74%; p<.001), and total parenteral nutrition at discharge (9.09% vs. 2.66%; p=0.041). Organ/space surgical site infection was an independent risk factor for unplanned readmission (OR=9.598, CI [2.070-44.513], p=0.004) by multivariable analysis.

CONCLUSION

Unplanned readmissions after liver resection are frequent in pediatric patients. Organ/space surgical site infections may identify patients at increased risk for unplanned readmission. Strategies to reduce these complications may decrease morbidity and costs associated with unplanned readmissions.

Palliative Chemotherapy and the Surgical Oncologist

Outcomes are improving for patients with advanced cancer, in part because of increasing diversity and efficacy of systemic therapy, often described as "palliative chemotherapy." Patients with advanced cancer receiving systemic treatment sometimes require surgical interventions, and their cancer care teams must collaborate to optimally manage medical and surgical challenges while also considering patients' goals and values. Structured communication can overcome the inherent ambiguity of the term "palliative chemotherapy" and facilitate optimal quality of care and quality of life for patients with advanced cancer who require surgical interventions.

Complex Wound Management Using Negative Pressure Wound Therapy With Instillation and Dwell Time in a Cancer Care Setting

INTRODUCTION

Unresolved wound healing represents a major health care cost with a negative impact on patient quality of life, especially among oncology patients who exhibit a delay in the wound healing cascade due to chemotherapy and radiation. In order to address this problem, the author utilized negative pressure wound therapy (NPWT) with instillation and dwell time (NPWTi-d) to cleanse wounds of debris and help promote healing.

OBJECTIVE

The author examines the impact of NPWTi-d on multiple indicators of wound healing progress in 6 cancer patients with complex wounds and multiple comorbidities.

MATERIALS AND METHODS

The NPWTi-d was initiated with instillation of normal saline or 0.125% hypochlorite solution, which was allowed to dwell for 3 to 20 minutes, followed by 2 to 3.5 hours of -125 mm Hg continuous negative pressure. Dressing changes were performed every 2 to 3 days. Debridements, incision and drainage, and antibiotics were administered as necessary.

RESULTS

A total of 1 woman and 5 men (average age, 62 years; range, 53-78 years) presented with the following wounds: surgical dehiscence (n = 3), pressure injury (n = 1), chronic seroma (n = 1), and abdominal wall abscess (n = 1). Malignancy was not detectable in any wounds. Patient comorbidities included diabetes, hypertension, and past treatment for cancers. The NPWTi-d was applied for 1 to 2 weeks, after which the wounds exhibited a reduction in slough, an improvement in granulation tissue, and a decrease in wound volume. Wounds were closed with a flap or transitioned to conventional NPWT prior to discharge home or to a rehabilitation facility for outpatient recovery.

CONCLUSIONS

As shown in this case series, NPWTi-d was a beneficial tool for cleansing the wound bed, thus creating a moist, closed wound environment conducive to healing. Using NPWTi-d supported the formation of a healthy wound bed and contributed to rapid, positive outcomes in this patient population.

Endophthalmitis Incidence of Cancer Patients After Cataract Surgery: A Nationwide Matched Cohort Study in Taiwan

PURPOSE

To compare the incidence rate of endophthalmitis after cataract surgery between cancer cohort and matched noncancer cohort.

DESIGN

Matched cohort study.

METHODS

Patients with cataract surgery of both eyes among a nationwide cancer cohort and 1:1 matched noncancer cohort were enrolled from the years 1998 to 2012 in the Taiwan National Health Insurance Research Database. Both the cancer group and the control group were followed for 3 months after the cataract surgery to obtain the rate of endophthalmitis.

RESULTS

There were 23 362 patients each in the cancer cohort and in the matched noncancer cohort. The mean age of receiving first cataract surgery was 71 years. The mean duration of receiving cataract surgery was 4.3 years after cancer diagnosis. The mean duration between 2 cataract surgeries was 8-9 months. The rate of endophthalmitis within 3 months after cataract surgery was similar between the 2 study groups: 2.4‰ (95% confidence interval = 1.9‰-2.8‰) for the cancer group and 2.3‰ (95% confidence interval = 1.9‰-2.8‰) for the noncancer group, respectively (P = .892).

CONCLUSIONS

Cancer patients have a similar risk of endophthalmitis following cataract surgery as the noncancer population, and the current study suggests that cataract surgery can be considered as appropriately indicated for cancer patients.
