BACKGROUND: Testicular ischemia requires timely diagnosis and definitive management to avoid serious consequences such as orchiectomy. It is almost always caused by testicular torsion; however, there are other causes to be aware of.
METHODS: A 32-year-old man developed testicular ischemia following a laparoscopic robotic-assisted inguinal hernia repair with preperitoneal mesh. The ischemia progressed to a fully infarcted testicle with no evidence of torsion on subsequent surgical exploration. He ultimately did require an orchiectomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: While extremely rare, testicular ischemia or infarct must be considered in patients presenting with testicular pain shortly after inguinal hernia repair. Emergent surgical evaluation and loosening of the hernia mesh may be required to salvage the testicle.

UNASSIGNED: The Hydrus microstent was approved by the FDA in August 2018 for use with cataract surgery to reduce IOP in patients with mild to moderate primary open angle glaucoma (POAG). Pivotal clinical trials demonstrated its overall safety and efficacy in lowering IOP. However, malpositioning of the implant can result in uveitis-glaucoma-hyphema (UGH) syndrome necessitating device explantation. Here we report four such cases and their associated challenges. We also highlight the importance of early recognition of post-operative complications for ease of implant removal.
UNASSIGNED: Case 1: A 75-year-old female patient was referred for chronic granulomatous anterior uveitis with cystoid macular edema (CME) and uncontrolled IOP in the left eye after cataract extraction with Hydrus implantation. On gonioscopy, the implant was occluded and embedded in the iris. The patient underwent removal of the Hydrus implant 10 months after the initial surgery with canaloplasty to control IOP.Case 2: A 71-year-old male patient on dual anti-platelet developed intraoperative hyphema during cataract extraction with Hydrus microstent in the right eye. Post-operatively, clopidogrel was stopped, but hyphema persisted with uncontrolled IOP. The Hydrus was noted to be syneched against the iris face. The patient underwent anterior chamber washout with Hydrus explantation and Ahmed glaucoma valve implantation 16 days after the first surgery.Case 3: A 76-year-old patient developed persistent granulomatous anterior uveitis in the left eye after cataract extraction with Hydrus microstent. On gonioscopy, the Hydrus ostium was seen resting on the iris without occlusion, and the patient underwent Hydrus removal with nasal goniotomy 3 months after initial surgery.Case 4: A 63-year-old patient underwent cataract extraction with endoscopic cyclophotocoagulation and a complex Hydrus microstent implantation requiring multiple attempts. Eleven months later, the patient was found to have uveitis-glaucoma-hyphema syndrome and macular edema, and the Hydrus was noted to be insufficiently inserted and posteriorly rotated with contact against the iris. The Hydrus was explanted, and nasal goniotomy was performed.
UNASSIGNED: Hydrus microstents that are malpositioned can result in persistent uveitis-glaucoma-hyphema syndrome. Explantation between 2 weeks and 11 months successfully resolved post-operative uveitis and hyphema, but all cases required additional glaucoma-hyphema syndrome. Early recognition is important since late removal was more challenging due to the implant becoming embedded in the iris.

BACKGROUND: Postoperative retropharyngeal hematoma (PRH) and related dyspnea are rare but life-threatening complications following anterior cervical discectomy and fusion (ACDF) that require urgent recognition and treatment. However, current knowledge of PRH after ACDF is limited. Meanwhile, whether the morphological features of upper airway are the risk factors of PRH remains unknown.
OBJECTIVE: The study aimed to investigate the incidence, clinical features, and risk factors, especially the morphological features of upper airway, of PRH and related dyspnea following ACDF.
METHODS: A nested case‒control study.
METHODS: Consecutive patients who underwent ACDF at a single institute from January 2010 to December 2021 were retrospectively reviewed.
METHODS: The outcome measures included the incidence, clinical features, intervention, outcome and risk factors for PRH and related dyspnea.
METHODS: All patients with PRH were classified into the hematoma group. For each PRH subject, 3 control subjects without PRH were randomly selected as the control group. The clinical features, interventions and outcomes of patients were described. Potential risk factors were evaluated, including demographics, comorbidities, surgical characteristics, coagulation function, blood loss, preoperative blood pressure, and the morphological features of upper airway [prevertebral soft tissue thickness (PVT) and location of transverse arytenoid muscle (TAM) and epiglottis]. Univariate tests and multivariable logistic regression analysis were used to determine the risk factors for PRH. Subgroup analysis was also conducted for PRH patients with and without dyspnea.
RESULTS: Among the 10615 patients who underwent ACDF, 18 (0.17%) developed PRH. The median time from the index surgery to PRH formation was 8.5 hours (25 and 75 percentile: 4 hours to 24 hours). All the PRH patients initially presented with wound swelling. Twelve (0.11%) patients presented dyspnea due to PRH, 2 of whom received urgent intubation and 1 of whom received emergent tracheotomy. All patients underwent hematoma evacuation, and most of them presented with completely relieved symptoms after evacuation, except for 1 patient who died from ischemic hypoxic encephalopathy. A level between the epiglottis and the TAM (LET) greater than 2, ossification of posterior longitudinal ligament (OPLL) and higher diastolic blood pressure (DBP) before surgery were found to be risk factors for PRH formation. Subgroup analysis revealed that a smaller prevertebral soft tissue thickness at C5 was associated with the development of dyspnea.
CONCLUSIONS: This study is the largest study to date focusing on the PRH and related dyspnea after ACDF. Our study showed that the incidences of PRH and related dyspnea after ACDF were 0.17% and 0.11%, respectively. The predominant symptoms of PRH were wound swelling and acute dyspnea. Most PRH cases occurred in the acute postoperative period. We demonstrated the risk factors for PRH to be (1) OPLL, (2) LET≥2 and (3) higher DBP before surgery and advocate paying increased attention to upper airway morphological features for identifying the risk of PRH after ACDF. With urgent recognition and timely intervention, severe clinical outcomes could be avoided.

Introduction: Patients who undergo surgery may require a blood transfusion and patients undergoing major colorectal surgery are more prone to preoperative and perioperative anemia. Blood transfusions have, however, long been associated with inflammatory and oncological complications. We aim to investigate the effects of an optimal implementation of a patient blood management (PBM) program in our hospital. Methods: This study retrospectively reviewed data from two different prospectively maintained databases of all patients undergoing elective major colorectal surgery with either a laparoscopic, open, or robotic approach from January 2017 to December 2022 at two different high-volume colorectal surgery Italian centers: the Colorectal Surgery Unit of Fondazione Policlinico Campus Bio-Medico in Rome and the Colorectal Surgery Unit of Fondazione Cardinale Panico in Tricase (Lecce). Our study compares the first group, also known as pre-PBM (January 2017-December 2018) and the second group, known as post-PBM (January 2021-December 2022). Results: A total of 2495 patients, who satisfied the inclusion and exclusion criteria, were included in this study, with, respectively, 1197 patients in the pre-PBM group and 1298 in the post- PBM group. The surgical approach was similar amongst the two groups, while the operative time was longer in the pre-PBM group than in the post-PBM group (273.0 ± 87 vs. 215.0 ± 124 min; p < 0.001). There was no significant difference in preparatory Hb levels (p = 0.486), while anemia detection was significantly higher post-PBM (p = 0.007). However, the rate of transfusion was drastically reduced since the implementation of PBM, with p = 0.032 for preoperative, p = 0.025 for intraoperative, and p < 0.001 for postoperative. Conclusions: We confirmed the need to reduce blood transfusions and optimize transfusion procedures to improve short-term clinical outcomes of patients. The implementation of the PBM program was associated with a significant reduction in the rate of perioperative transfusions and an increase in only appropriate transfusions.

Background: Current treatments with urate-lowering therapy (ULT) are effective for most patients with gout. However, approximately 10% of these patients do not respond well to ULT and develop chronic tophus lesions. Objective: This study aimed to evaluate the efficacy of surgery involving the shaver technique against chronic tophus lesions. Methods: This single-center, retrospective cohort study included 217 patients who had cumulatively undergone 303 shaver-assisted procedures between 2002 and 2018. Surgical outcomes were assessed in terms of the length of hospital stay (LOS) and wound healing time. Results: LOS and wound healing time were longer in patients with a preoperative tophus infection and lower extremity lesions than in those without infection and with upper extremity lesions (respectively, LOS: 12.7 vs. 8.6 days; wound healing time: 22.7 vs. 16.3 days). However, factors such as age, sex, body mass index, renal function, or uricemia level exerted no significant effect on surgical outcomes. Conclusion: Surgery involving the shaver technique should be performed before tophus infection. Clinical outcomes tend to be better for upper extremity lesions than for lower extremity lesions.

BACKGROUND: Malignant chest wall tumors need to be excised with wide resection to ensure tumor free margins, and the reconstruction method should be selected according to the depth and dimensions of the tumor. Vascularized tissue is needed to cover the superficial soft tissue defect or bone tissue defect. This study evaluated differences in complications according to reconstruction strategy.
METHODS: Forty-five patients with 52 operations for resection of malignant tumors in the chest wall were retrospectively reviewed. Patients were categorized as having superficial tumors, comprising Group A with simple closure for small soft tissue defects and Group B with flap coverage for wide soft tissue defects, or deep tumors, comprising Group C with full-thickness resection with or without mesh reconstruction and Group D with full-thickness resection covered by flap with or without polymethyl methacrylate. Complications were evaluated for the 52 operations based on reconstruction strategy then risk factors for surgical and respiratory complications were elucidated.
RESULTS: Total local recurrence-free survival rates in 45 patients who received first operation were 83.9% at 5 years and 70.6% at 10 years. The surgical complication rate was 11.5% (6/52), occurring only in cases with deep tumors, predominantly from Group D. Operations needing chest wall reconstruction (p = 0.0016) and flap transfer (p = 0.0112) were significantly associated with the incidence of complications. Operations involving complications showed significantly larger tumors, wider areas of bony chest wall resection and greater volumes of bleeding (p < 0.005). Flap transfer was the only significant predictor identified from multivariate analysis (OR: 10.8, 95%CI: 1.05-111; p = 0.0456). The respiratory complication rate was 13.5% (7/52), occurring with superficial and deep tumors, particularly Groups B and D. Flap transfer was significantly associated with the incidence of respiratory complications (p < 0.0005). Cases in the group with respiratory complications were older, more frequently had a history of smoking, had lower FEV1.0% and had a wider area of skin resected compared to cases in the group without respiratory complications (p < 0.05). Preoperative FEV1.0% was the only significant predictor identified from multivariate analysis (OR: 0.814, 95%CI: 0.693-0.957; p = 0.0126).
CONCLUSIONS: Surgical complications were more frequent in Group D and after operations involving flap transfer. Severe preoperative FEV1.0% was associated with respiratory complications even in cases of superficial tumors with flap transfer.

OBJECTIVE: This study aims to evaluate the efficacy of the profunda artery perforator (PAP) flap in head and neck reconstruction.
METHODS: A single arm meta-analysis was performed for flap survival rate (primary outcome), reoperation for major complication, and overall complication rates (secondary outcomes).
RESULTS: The search strategy yielded a total of 295 potentially relevant publications, of which 13 were included. A total of 305 patients (males: 80.8%, n = 232/281), with a median age of 56.1 years (n = 305/305; 95% CI 53.9-63), who underwent a total of 307 PAP flap reconstructions for head and neck defects were included. Flap survival rate was 100% (n = 306/307; 95% CI 99.6%-100%), with a reoperation rate for major complications of 3.7% (n = 15/307; 95% CI 1.85%-6.1%) and an overall complication rate of 26.5% (n = 92/307; 95% CI 15.7%-38.9%). Notable postoperative complications included wound dehiscence (n = 15/307, 4.9%), delayed healing (n = 14/307, 4.6%), and wound infection (n = 12/307, 3.9%). Partial flap necrosis and hematoma occurred in 2.6% of cases (n = 8/307), while arterial and venous thrombosis were documented in 0.7% (n = 2/307) and 1.3%, respectively (n = 4/307).
CONCLUSIONS: The application of the PAP flap in head and neck reconstructions showed several favorable aspects, such as an exceptionally low flap failure rate, versatility in achieving variable dimensions, and a relatively low incidence of complications. PAP flap might be considered as a compelling alternative to the traditionally employed soft tissue free flaps in head and neck reconstruction.

Necrotizing fasciitis (NF), commonly known as necrotizing soft tissue infection (NSTI), or flesh-eating disease is a rare but rapidly fatal aggressive bacterial infection of soft tissue and deep skin that results in the destruction of the underlying fascia. Symptoms include fever, tachycardia, hypotension, leukocytosis, pain, and large areas of red and swollen skin. Early diagnosis and aggressive management are compulsory for a better prognosis. In this case report, we present a 58-year-old obese woman who initially presented to the emergency department three weeks post-sleeve gastrectomy with hernia repair and was initially suspected of having a large, uncomplicated abdominal wall abscess. Several repeated drainages of the abdominal wall abscess and continued deterioration of the patient revealed foul-smelling, necrotic tissue and the subsequent diagnosis of NF. This case report highlights the importance of high clinical suspicion for NF and early, aggressive debridement and treatment to improve patient outcomes.

BACKGROUND: This study aimed to clarify the quantitative threshold of intraoperative radiological parameters for suspecting posterior malposition of the oblique lumbar interbody fusion (OLIF) cage triggering contralateral radiculopathy.
METHODS: We measured the sagittal center and axial rotation angle (ARA) of the cage using postoperative computed tomography (CT) in 130 patients (215 cages) who underwent OLIF. The location of the cage tip was determined from axial magnetic resonance imaging in selected cases based on CT simulations to assess whether the cage was in contact with the contralateral exiting nerve or whether the surgical instruments could contact the nerve during intradiscal maneuvers.
RESULTS: The sagittal center of the cages was on average 41.5% from the anterior edge of the endplate (shown as AC/AP value: anterior end plate edge-cage center/anterior-posterior endplate edge ×100%), and posterior cage positioning ≥50% occurred in 14% of the cages. The ARA was -2.9°, and posterior oblique rotation of the cages ≥10° (ARA ≤ -10°) was observed in 13%. CT simulation showed that the cage tip could directly contact the contralateral nerve when the cage was placed deep in the posterior portion ≥50% of the AC/AP values with concomitant posterior axial rotation ≥10° (ARA ≤ -10°), or deep in an extremely rare portion ≥60% of the AC/AP values with posterior axial rotation ≥0° (ARA ≤ 0°). Six percent of the cages (13/215) were placed in these posterior oblique areas (potential contact area: PCA). Three cages in the PCA were in direct contact with the contralateral nerves, and 9 were placed deep just anterior to the nerves. Symptomatic contralateral radiculopathy occurred in 2 cages (2/13/215, 15.3%/0.9%).
CONCLUSIONS: Two intraoperative radiological parameters (AC/AP and ARA) measurable during OLIF procedures may become practical indicators for suspecting cage malposition in PCA and may be available when determining whether to consider cage revision intraoperatively to a more ventral disc space or anteriorly from the opposite endplate edge.
METHODS:

BACKGROUND: The purpose of this study was to compare safety and efficacy outcomes between immediate breast reconstruction (IBR) and mastectomy alone in locally advanced breast cancer patients.
METHODS: We conducted a comprehensive literature search of PUBMED, EMBASE, and Cochrane databases. The primary outcomes evaluated were overall survival, disease-free survival, and local recurrence. The secondary outcome was the incidence of surgical complications. All data were analyzed using Review Manager 5.3.
RESULTS: Sixteen studies, involving 15,364 participants were included in this meta-analysis. Pooled data demonstrated that patients underwent IBR were more likely to experience surgical complications than those underwent mastectomy alone (HR: 3.96, 95%CI [1.07,14.67], p = 0.04). No significant difference was found in overall survival (HR: 0.94, 95%CI [0.73,1.20], p = 0.62), disease-free survival (HR: 1.03, 95%CI [0.83,1.27], p = 0.81), or breast cancer specific survival (HR: 0.93, 95%CI [0.71,1.21], p = 0.57) between IBR group and Non-IBR group.
CONCLUSIONS: Our study demonstrates that IBR after mastectomy does not affect the overall survival and disease-free survival of locally advanced breast cancer patients. However, IBR brings with it a nonnegligible higher risk of complications and needs to be fully evaluated and carefully decided.
