ABSTRACT
Postoperative infectious complications are extremely important to surgeons and the entire medical care team. Among these complications, surgical site infection (SSI) appears to be one of the earliest and most prevalent events and is considered an inherent complication of surgical procedures. In oncological patients submitted to resections of digestive system tumors, there is a confluence of several risk factors for SSI, making it necessary to establish measures to maximize the control of this condition to provide a better prognosis for these patients. Some risk factors for SSI are the manipulation of structures hosting the highest density of pathogenic microorganisms, such as the colon, the patient's performance status, the patient's nutritional status, the use of chemotherapy and/or radiotherapy, and the surgical procedure itself, which tends to last longer and be more complex than surgeries for benign conditions of the digestive system. Therefore, this review sought to provide a qualitative analysis and a summary of the literature regarding the SSI of postoperative tumor patients who underwent surgical resection and were well-structured postoperatively, to provide objective data on this problem, and alert about the well-structured needs of individualized pre-, peri-, and post-protocols to avoid the development of these events.

OBJECTIVES: To identify the infection rate in patients with combined pelvic ring and bladder injuries. Secondary aims included identifying treatment and injury factors associated with infection. DESIGN: Retrospective review. SETTING: Single Level I Tertiary Academic Center. PATIENTS SELECTION CRITERIA: All patients over a 12-year period with combined pelvic ring and bladder injuries were evaluated. Exclusion criteria were nonoperative management of the pelvic ring, isolated posterior fixation, and follow-up <90 days. OUTCOME MEASURE AND COMPARISONS: Primary outcome measured was deep infection of the anterior pelvis requiring surgical irrigation and debridement. RESULTS: In total, 106 patients with anterior stabilization of the pelvis in the setting of a bladder injury were included. Seven patients (6.6%) developed a deep infection and required surgical debridement within 90 days. Patients undergoing open reduction and internal fixation with plating of the anterior pelvis and acute concomitant bladder repair had an infection rate of 2.2% (1/43). Patients undergoing closed reduction and anterior fixation with either external fixation or percutaneous rami screw after bladder repair had an infection rate of 17.6% (3/17). There was a higher infection rate among patients with combined intraperitoneal (IP) and extraperitoneal (EP) bladder injuries (23%) when compared with those with isolated EP (3.8%) or IP (9.1%) bladder injuries (P = 0.029). CONCLUSIONS: Acute open reduction and internal fixation of the anterior pelvis in patients with combined pelvic ring and bladder injuries has a low infection rate. Patients with combined IP and EP bladder injuries are at increased risk of infection compared with those with isolated IP and EP injuries. LEVEL OF EVIDENCE: Prognostic Level III.

BACKGROUND: Incisional hernia is frequently observed after open colorectal cancer surgery, and should be considered a serious short- and long-term health issue. The present study evaluated the efficacy of small-bite abdominal closure in reducing the incidence of incisional hernia in this patient group. METHODS: An RCT was conducted between June 2019 and June 2022. A total of 173 patients who underwent open colorectal cancer surgery were assigned randomly to one of two groups to undergo fascial closure with either small bites (87) or conventional bites (86). The incisional hernia rate was accepted as the primary outcome, and surgical-site infection as the secondary outcome. RESULTS: The incisional hernia rates at 1 year were 7 and 27% in the small- and conventional-bite groups respectively (P < 0.001). This rate increased to 9 and 31% at the end of the second year (P < 0.001). Surgical-site infections occurred in 18% of the small-bite group and 31% of the conventional-bite group (P = 0.03). Compared with the conventional-bite group, the small-bite group had higher suture/wound length ratios (mean(s.d.) 5.18(0.84) versus 3.67(0.57); P < 0.001) and a longer fascial closure time 14.1(4.64) versus 12.9(2.39) min; P = 0.03). CONCLUSION: Small-bite closure with 5-mm tissue bites placed 5 mm apart reduced the incidence of incisional hernia and surgical-site infection after open colorectal cancer surgery.

<b>Introduction:</b> Loop ileostomy reversal (LIR) procedure is still associated with a relatively high risk of complications. Surgical site infection (SSI) is the most common complication in this group of patients. SSI leads to prolonged hospital stays, delays the adjuvant therapy, and increases hospital costs.<b>Aim:</b> The aim of the study was to analyze the risk factors for SSI in patients following loop ileostomy reversal procedure.<b>Material and methods:</b> A single-center retrospective analysis was conducted in a tertiary reference center. Finally, 65 patients following loop ileostomy reversal procedure performed between 2018 and 2022 were enrolled in the study. Data were collected retrospectively based on the available medical charts. The study group comprised 23 women (35%) and 42 men (65%) with a mean age of 48.9 14.5 years and a mean body mass index of 24.3 4.9 kg/m<sup>2</sup> . The most common indication for index surgery was ulcerative colitis (33%) and colorectal cancer (29%). Preferably, handsewn anastomosis was performed (n = 42; 64.6%).<b>Results:</b> The most important parameter evaluated in the above study was the diagnosis of surgical site infection, which influenced e.g. hospitalization after surgery, the need for antibiotic therapy, or C-reactive protein (CRP) values. Nine patients (13.8%) were diagnosed with SSI during their hospital stay (more than 86% without SSI). In the group with SSI, hospital stay exceeded 13 days compared to almost 6 days in the group without SSI (P = 0.00009). The time of the procedure had a statistically significant correlation with antibiotic therapy introduction (P = 0.01). The type of intestinal anastomosis had a significant impact on the operative time (P = 0.0011) and the time of hospital stay after surgery (P = 0.04).<b>Conclusions:</b> Most of the analyzed clinical factors were directly related to the impact on the duration of postoperative hospitalization. The duration of hospitalization is an independent and undeniable factor increasing the risk of other postoperative complications and significantly increasing the cost of hospitalization. Another factor that has a large clinical impact on postoperative treatment is the presence of comorbidities which make patients more likely to develop SSI, CRP increase, or the need for antibiotic therapy. An important factor was the level of CRP, the elevated value of which may be a predictor of many negative aspects in postoperative treatment.

OBJECTIVE: The objective of the scoping review will be to understand and describe risk factors associated with surgical site infection (SSI) in an orthopaedic surgery population in Sub-Saharan Africa and South Africa. This paper describes the protocol that will be used for the scoping review. METHOD: A comprehensive literature search will be conducted using MEDLINE (PubMed), CINAHL (EBSCO), Embase and Cochrane Libraries to identify articles meeting the inclusion criteria, including both published and grey literature, in order to provide a broad overview of the reported risk factors associated with patients who have undergone an orthopaedic surgery with an outcome of SSI within 90 days of a procedure. Additional studies will be sourced by exploring the reference list of included eligible studies. By using a combination of the Population, Exposure, Outcome framework, terms and synonyms related to each category, in different variations, along with Boolean operators (AND, OR, NOT) in the search strategy, identified comprehensive and relevant literature for the scoping review. RESULTS: It is anticipated the results will provide a baseline of risk factors that will inform the development of a risk assessment tool for clinical use. CONCLUSION: This protocol will inform the development of a scoping review to describe factors associated with SSIs following orthopaedic surgery in Sub-Saharan Africa and South Africa.

Background: Abdominal surgery is considered a high-risk procedure for the development of surgical site infection (SSI). Few studies have evaluated the relative importance of surgical site infection risk factors in terms of consistency in abdominal surgery. Therefore, this comprehensive review article mapped and summarized the evidence aimed to determine the relative importance of the risk factors and incidence of SSIs in abdominal surgery. Methods: A literature review was conducted using electronic databases and search engines such as Scopus, PubMed, and Web of Science up to March 16, 2023. There was no language restriction for the papers to be included in the study. The relative consistency of the risk factors was measured and evaluated using the methodology of the Joanna Briggs Institute. Original peer-reviewed cohort and case-control studies were included if all types of SSIs were included. Meta-analysis was performed to determine the pooled estimates of SSI incidences. Results: Of 14,237 identified records, 107 articles were included in the review. The pooled incidence of SSI was 10.6% (95% CI: 9.02-12.55%, χ2=12986.44, P<0.001). Operative time and higher wound class were both significant consistent risk factors for SSI incidence. Patients' educational status, malnutrition, functional status, and history of neurological/psychiatric disorders were all candidates for consistent risk factors, with insufficient evidence. Conclusion: The findings of the present study indicated that SSI in abdominal surgery was a multifactorial phenomenon with a considerable risk and had different risk factors with various relative importance. Determining the relative importance of the risk factors for the prevention and control of SSI is strongly recommended.This manuscript has been released as a preprint at the research square: (https://doi.org/10.21203/rs.3.rs-3219597/v1).

BACKGROUND: Postoperative infection of breast implants can lead to implant removal and other complications. This study aimed to investigate the presence of costal cartilage infection following breast implant surgery and the diagnostic role of PET/CT in identifying this rare complication. PATIENTS AND METHODS: A retrospective study included 16 patients with persistent infections after breast implant removal surgery. Patients underwent PET/CT scans before surgery, and surgical plans were made based on PET/CT findings. Surgical procedures were guided by PET/CT, and specimens were collected for pathological examination and microbiological culture. Follow-up assessments were performed at 1, 3, and 12 months postoperatively. RESULTS: Among the 16 patients, 11 were diagnosed with costal cartilage infection, whereas 5 had subcutaneous soft tissue infections. PET/CT accurately identified costal cartilage infection in all cases and localized the infected costal cartilage in the majority of cases. Microbiological culture results showed various pathogens. All patients were cured with one or staged surgery. CONCLUSION: Costal cartilage infection following breast implant surgery is a significant concern. PET/CT plays a crucial role in the accurate diagnosis and localization of infected costal cartilage, aiding in appropriate surgical management. Patients should be closely monitored for the possibility of costal cartilage infection when experiencing persistent symptoms after breast implant surgery.

The meta-analysis sought to evaluate and compare the effect of obesity on surgical site wound problems in subjects after primary ovarian cancer surgery. The results found by this meta-analysis were analyzed, and then odds ratio (OR) and mean difference (MD), at 95% confidence intervals (CIs), were calculated. These models might be dichotomous or contentious, random, or fixed effect models. The current meta-analysis included nine exams from 2009 to 2023, including 4362 females with primary ovarian cancer surgeries. Obesity had a significantly higher risk of surgical site wound infections (OR, 2.90; 95% CI, 2.27-3.69, p < 0.001), and wound problems (OR, 4.14; 95% CI, 1.83-9.34, p < 0.001) compared to non-obesity in females with primary ovarian cancer surgeries. It was revealed, by examining the data, that obesity was associated with significantly higher incidence of surgical site wound infections, and wound problems compared to non-obesity in females with primary ovarian cancer surgeries. However, attention should be given to the values because some of the comparisons included a small number of chosen studies,.

Surgical site infections (SSIs) following major lower limb amputation (MLLA) in vascular patients are a major source of morbidity. The objective of this systematic review was to determine the incidence of SSI following MLLA in vascular patients. This review was prospectively registered with the International Prospective Register of Systematic Reviews (CRD42023460645). Databases were searched without date restriction using a pre-defined search strategy. The search identified 1427 articles. Four RCTs and 21 observational studies, reporting on 50 370 MLLAs, were included. Overall SSI incidence per MLLA incision was 7.2% (3628/50370). The incidence of SSI in patients undergoing through-knee amputation (12.9%) and below-knee amputation (7.5%) was higher than the incidence of SSI in patients undergoing above-knee amputation, (3.9%), p < 0.001. The incidence of SSI in studies focusing on patients with peripheral arterial disease (PAD), diabetes or including patients with both was 8.9%, 6.8% and 7.2%, respectively. SSI is a common complication following MLLA in vascular patients. There is a higher incidence of SSI associated with more distal amputation levels. The reported SSI incidence is similar between patients with underlying PAD and diabetes. Further studies are needed to understand the exact incidence of SSI in vascular patients and the factors which influence this.

OBJECTIVE: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients. STUDY DESIGN: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively. RESULTS: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, ß = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time. CONCLUSION: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.
Outcomes after cesarean delivery were assessed for 328 patients with morbid obesity.High transverse skin incision for cesarean delivery was associated with increased wound morbidity and wound infection.Prospective studies will be needed to determine if skin incision placement causes wound morbidity.

BACKGROUND AND PURPOSE: The aim of our study was to investigate change in modifiable risk factors following preoperative optimization and whether risk of superficial surgical site infection (SSI) after total joint arthroplasty (TJA) could be reduced. METHODS: This is a prospective study of implementation of a preoperative optimization pathway for patients waiting for primary TJA. Information regarding the intervention arm was collected from January 2019 to January 2021, first at decision for operation and then at preoperative assessment 1 week prior to operation. The control arm was included between August 2018 and September 2020 after receiving conventional preoperative preparation and information gathered at preoperative assessment. Follow up occurred 6 weeks postoperatively for both groups. The primary outcome was postoperative superficial SSI. RESULTS: The optimization effort resulted in improvement of weight, anemia, HbA1c, vitamin D, and patient engagement. At preoperative assessment the baseline characteristics of the 2 groups were similar except that the intervention group had substantially more comorbidities. Regarding superficial SSI, association was found with BMI ≥ 30 and HbA1c ≥ 42 mmol/mol in the control group but not in the intervention group. When corrected for differences in ASA classification (reflecting comorbidities), age, and sex, being in the intervention group was associated with lower odds of occurrence of superficial SSI compared with the control group (OR 0.64, 95% confidence interval 0.42-0.97). CONCLUSION: We showed that preoperative optimization in a structured cooperation between hospital and primary care was associated with a reduced risk of superficial SSI.

BACKGROUND: Diabetes mellitus (DM) is a worldwide pandemic affecting 500 million people. It is known to be associated with increased susceptibility to soft tissue infections (STI). Despite being a major public health burden, the literature relating the effects of DM and the presentation, severity and healing of STIs in general surgical patients remain limited. METHOD: We conducted a retrospective review of all patients admitted with STI in a tertiary teaching hospital over a 12-month period. Patient demographics and surgical outcomes were collected and analysed. RESULTS: During the study period, 1059 patients were admitted for STIs (88% required surgery). DM was an independent risk factor for LOS. Diabetic patients presented with higher body-mass index (28 vs. 26), larger abscess size (24 vs. 14 cm2) and had a longer length of stay (4.4 days vs. 2.9 days). They also underwent a higher proportion of wide debridement and application of negative pressure wound therapy (42% vs. 35%). More diabetic patients underwent subsequent re-operation within the same sitting (8 vs. 4). Diabetic patients were two times more likely to present with carbuncles (p = 0.02). CONCLUSION: The incidence of STIs among DM patients represent a significant disease burden, surgeons should consider intensive patient counselling and partnering with primary care providers in order to help reduce the incidence of future STI admissions based upon lifestyle modification and glucose control.

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA ECMO) is a well-established treatment for severe cardio-pulmonary failure. The use of large bore cannulas in the femoral vessels for an extended period has been associated with significant wound complications. There is a lack of data analyzing risk factors that can mitigate such complications. The primary purpose of this study was to identify modifiable risk factors associated with femoral wound complications after VA ECMO decannulation. METHODS: Retrospective analysis of wound complications in patients following VA ECMO decannulation from 2014-2021 at a single academic institution were analyzed. Wound complications were defined as wound infection, dehiscence, or those wounds that were deliberately opened to promote healing by secondary intention. RESULTS: Sixty patients underwent decannulation of VA ECMO with operative repair of the femoral artery. Fifteen patients were identified to have wound complications, eight (53%) of these had infection. Fourteen (93%) patients had wound dehiscence or had their wound purposely opened at bedside. Univariate analysis revealed no association of access-related complication with higher Body Mass Index (BMI, 28.3 vs. 32.7 kg/m2, P=0.110) but here was a trend in having more wound complications in individuals with COVID-19 infection (6.7% vs. 26.7%, P=0.058). Patients that had dual cannulation with the arterial and venous cannulas in the same groin had significantly more wound complications compared to single cannulation arterial and venous cannulas in separate groins (57.8% vs. 93.3%; P=0.012). Multivariate analysis revealed same side cannulation (OR 18.05, 95% CI 1.44-226.18, P=0.025) and COVID-19 infection (OR 18.18, 95% CI 1.50-220.66, P=0.023) were independent predictors of wound complications. CONCLUSIONS: Wound complications after VA ECMO decannulation is associated with COVID-19 infection and having venous and arterial cannulas in the same groin. We recommend that the arterial and venous cannulation be placed in different groins in patients that require VA ECMO.

OBJECTIVES: To determine if rates of pin site infection and surgical site infection among patients managed with primary closure after external fixator removal were similar to those allowed to heal secondarily. DESIGN: Retrospective cohort. SETTING: Urban/Suburban Academic Level I Trauma Center. PATIENT SELECTION CRITERIA: Patients who had received a lower extremity external fixator for provisional management before definitive fixation of lower extremity fractures were included with pin site wounds closed primarily or allowed to heal by secondary intention. OUTCOME MEASURES AND COMPARISONS: The rate of pin tract infection and surgical site infection following primary closure of external fixator pin sites relative to patients whose pin sites were allowed to heal through secondary intention. RESULTS: In total, 256 patients were evaluated: 143 patients (406 pin sites) in the primary closure group and 113 patients (340 in sites) in the secondary closure group. The average age was 49 ± 16 years. Sixty-five percent of included patients were male. There was no difference in pin tract infections between cohorts (primary = 0.5%, secondary = 1.5%, P = 0.26). External fixator duration in the primary closure group was 11.5 ± 8.4 days and 13.0 ± 8.1 days in the secondary closure group (P = 0.15). There was a greater rate of surgical site infections in the secondary intention cohort (15.9% vs. 7.7%, P = 0.047). CONCLUSIONS: There was no difference in pin site infection rate after primary pin site closure relative to patients who were allowed to heal through secondary intention. Furthermore, there was a lower rate of surgical site infection after primary closure. These results challenge the dogma of secondary closure for ex fix pin sites, suggesting that debridement and primary closure is a safe option for management of external fixator pin sites and may impart benefit in decreasing infection risk. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

We present a case of deep surgical site infection (SSI) at a spinal cord stimulator (SCS) trial implantation site, resulting from an allergic reaction to an unknown agent. A 38-year-old female with complex regional pain syndrome began an SCS trial, noting 100% pain relief for 5 days. Fluid drainage from the surgical site was reported on POD6 and trial leads were removed the following day. The patient was hospitalized with sepsis. Blood cultures revealed Staphylococcus aureus. MRIs showed skin breakdown and cellulitis of the paraspinal musculature extending into the epidural space. The patient was maintained with antibiotics and rigorous wound care for 9 days and the surgical site infection resolved. The patient proceeded to SCS implantation, and reported good pain relief with the implanted device.
This case report describes the treatment of an infection developed during a spinal cord stimulator (SCS) trial period. SCS are medical devices used to treat pain, they work by applying electrical current to the areas of the spinal cord that cause patients' pain. Before patients get an SCS device implanted, they often undergo a trial period first. During a trial, the stimulator device stays outside the body, and only the wires carrying electricity to the spinal cord are implanted. Typically, SCS trial and implantation procedures are safe and result in effective pain relief. However, infections are a dangerous potential complication that can result from these procedures. In our case, the patient developed an infection during an SCS trial period, likely resulting from an allergic reaction to their surgical dressings. The infection traveled down the wires and nearly reached the spinal cord. Since the infection was quickly identified and managed, devastating complications were avoided. The patient was able to get a permanent SCS after the infection was resolved, and had effective pain relief. Our report emphasizes the importance of using strict infection prevention techniques, and monitoring patients for signs of infection throughout SCS trials.

BACKGROUND/AIM: In colorectal cancer surgery, the risk of surgical site infection (SSI) is relatively high. The development of SSI is related to longer and costlier hospitalization and reduced quality of life; therefore, perioperative prevention of SSI is important. Chemical bowel preparation (CBP) combined with mechanical bowel preparation (MBP) may be more effective in preventing surgical site infection (SSI) compared to MBP alone. Since May 2021, we have been administering oral kanamycin and metronidazole as CBP, in addition to MBP, as a preoperative treatment for colorectal cancer surgery on the day before surgery. In this study, we investigated the clinical value of CBP in addition to MBP in colorectal cancer surgery using propensity score matching (PSM). PATIENTS AND METHODS: From January 2017 to December 2021, 136 consecutive patients underwent radical surgery for sigmoid colon and rectal cancer at the Osaka Metropolitan University Hospital. Patients were divided into two groups: CBP and N-CBP. In the N-CBP group, we performed only preoperative MBP, whereas in the CBP group, we performed preoperative CBP in addition to MBP. We retrospectively analyzed this relationship with PSM. RESULTS: Overall, 46 patients underwent preoperative CBP and MBP, 90 patients underwent preoperative MBP only. PSM was performed between the CBP and N-CBP groups based on the following ten factors: age, sex, diabetes mellitus, preoperative therapy, Glasgow Prognostic Score (GPS), operative time, blood loss, stoma, and pathological stage. After PSM, univariate and multivariate analyses of the relationship between SSI and clinicopathological factors were performed. Univariate analysis showed that age and CBP were correlated with the rate of SSI (p=0.039 and p=0.017, respectively), whereas sex was relatively correlated with the rate of SSI (p=0.066). The multivariate analysis of significant factors identified age of 75 or more and non-CBP as an independent risk factor for incisional SSI (HR=9.5; p=0.049 and HR=5.4×e-8; p=0.020). CONCLUSION: Preoperative CBP in addition to MBP was effective in preventing incisional SSI during colorectal cancer surgery.

BACKGROUND: In recent years, the development of robotic neurosurgery has brought many benefits to patients, but there are few studies on the occurrence of surgical site infection (SSI) after robot-assisted stereoelectroencephalography (SEEG). The purpose of this study was to collect relevant data from robot-assisted SEEG over the past ten years and to analyze the influencing factors and economic burden of surgical site infection. METHODS: Basic and surgical information was collected for all patients who underwent robot-assisted SEEG from January 2014 to December 2023. Logistic regression was used to analyze the factors influencing SSI according to different subgroups (radiofrequency thermocoagulation or epilepsy resection surgery). RESULTS: A total of 242 subjects were included in this study. The risk of SSI in the epilepsy resection surgery group (18.1%) was 3.5 times greater than that in the radiofrequency thermocoagulation group (5.1%) (OR 3.49, 95% CI 1.39 to 9.05); this difference was statistically significant. SSI rates in the epilepsy resection surgery group were associated with shorter surgical intervals (≤ 9 days) and higher BMI (≥ 23 kg/m2) (6.1 and 5.2 times greater than those in the control group, respectively). Hypertension and admission to the intensive care unit (ICU) were risk factors for SSI in the radiofrequency thermocoagulation group. Patients with SSIs had $21,231 more total hospital costs, a 7-day longer hospital stay, and an 8-day longer postoperative hospital stay than patients without SSI. CONCLUSIONS: The incidence of SSI in patients undergoing epilepsy resection after stereoelectroencephalography was higher than that in patients undergoing radiofrequency thermocoagulation. For patients undergoing epilepsy resection surgery, prolonging the interval between stereoelectroencephalography and epilepsy resection surgery can reduce the risk of SSI; At the same time, for patients receiving radiofrequency thermocoagulation treatment, it is not recommended to enter the ICU for short-term observation if the condition permits.

Surgery forms the backbone of treatment for most locoregional or advanced oral cavity squamous cell carcinoma. Unfortunately, infectious complications (including orocutaneous fistulas) are common following such extensive surgery and can afflict over half of patients. These complications can lead to delays in adjuvant treatment, prolonged hospitalization, reconstructive failure, and decreased quality of life. The frequency and morbidity associated with infectious complications has led to the search for pre-disposing risk factors; and, several have been identified, including both patient (e.g. diabetes) and surgical (e.g. operative time) factors. However, these findings are inconsistently reproduced, and risk factor modification has had a limited impact on rates of infectious complications. This is striking given that the likely contaminant-the oral microbiome-is a well-studied microbial reservoir. Because many oral cavity cancer surgeries involve violation of oral mucosa and the spillage of the oral microbiome into normally sterile areas (e.g. the neck), variance in oral microbiome composition and function could underly differences in infectious complications. The goal of this perspective is to highlight 1) this knowledge gap and 2) opportunities for studies in this domain. The implication of this line of thought is that the identification of oral microbial dysbiosis in patients undergoing surgery for oral cavity cancer could lead to targeted pre-operative therapeutic interventions, decreased infectious complications, and improved patient outcomes.
