Maintenance of a cement spacer as definitive treatment of post traumatic osteomyelitis, a case report.

Background Septic nonunion is a devastating outcome following a tibial plafond fracture, causing significantly increased morbidity and a lengthy recovery. Treatment options include antibiotics and irrigation and debridement procedures focused on preventing posttraumatic osteomyelitis. If these options fail, surgical intervention is necessary to clear infection and debride nonviable bone, often resulting in a substantial bony void. Masquelet technique and Cement augmentation are well studied, multi-stage procedures designed specifically for combatting these defects. These procedures are associated with significant patient burden, a long non-weight-bearing period, and a lengthy recovery. The case presented here today highlights a variation of these techniques that reduced the need for the standard second stage procedure and resulted in a quicker return to normal activity. Case A 51-year-old obese male presented with a septic nonunion with posttraumatic osteomyelitis following a tibial plafond fracture. The patient underwent implant removal with simultaneous irrigation and debridement of all nonviable bone resulting in a substantial bony void. The nonunion was then stabilized with an antibiotic tibial nail, and an antibiotic cement spacer to fill the bony void. The patient was allowed to partial weight bear post operatively and quickly progressed weight bearing status. By postoperative week eight, the patient’s activity level had returned to near his baseline, and the patient was not interested in another procedure to remove the spacer and bone graft. At this time, it was elected to permanently maintain the cement spacer, and only exchange it for bone graft as needed. By one-year, radiographic films demonstrating bony healing around the cement spacer, and the patient was back to full pain-free function. Conclusions Permanently maintaining the cement spacer in cement augmentation or the Masquelet technique allowed this patient to quickly progress weight-bearing status, regain function, and return to normal life without the need for the stage two procedure.

A 2-Stage Approach in Managing Diabetic Forefoot Ulcers.

Forefoot plantar ulcers in patients with diabetic neuropathy are considered to be primarily the result of increased shear forces applied over prominent plantar bony prominences. The purpose of this article is to describe a 2-stage treatment pathway utilizing an outpatient percutaneous tendon-Achilles lengthening (TAL) as the first stage procedure and subsequent proximal metatarsal osteotomy (MTO) as a second stage procedure for a persistent or recurrent ulcer. A consecutive 112 patients (146 feet), who presented to our Multidisciplinary Diabetic Foot Team clinics since February 2019 with plantar nonischemic forefoot ulcers were included in this study. Excluding the patients who died or were lost to follow-up, 96 feet were followed for a minimum 12 months (range 12-36 months). After TAL, patients were encouraged to walk in a walking cast for 6 weeks and were followed for a minimum 12 months. Patients with persistent or recurrent ulcers were investigated with magnetic resonance imaging scan, and based on intramedullary osteomyelitis and septic destruction of distal metatarsal, we describe a second-stage MTO with the 3 most common clinical presentations. Of 96 feet, none had infection or wound-related problems following TAL. Complete transection of the tendon was noted in 4 patients (4%) and heel callosity in 1 patient. In 92 feet (96%), the ulcers healed within 10 weeks (±4 weeks) after TAL but, in 12 feet (10%), the ulcer failed to heal or recurred. At a minimum 12 months after the second-stage MTO, none in this subgroup had recurrence of ulcer or a transfer lesion. TAL followed with a walking cast as an outpatient procedure was effective in healing forefoot ulcers in 96% of feet. Comparable to the widely practiced hand surgery Wide Awake Local Anesthesia No Tourniquet (WALANT) procedure, our approach involved active control of the degree of ankle dorsiflexion by the patient, and the procedure was proven to be safe and well tolerated. When the second-stage MTO was required to offload the forefoot, in our small cohort, patients had ulcer-free outcome for a minimum 12 months. Level IV, retrospective case series.

Clinicopathological characteristics of gastric cancer patients with dermatomyositis and analysis of perioperative management: a case series study.

This study aimed to investigate the clinical characteristics of gastric cancer (GC) patients with dermatomyositis (DM) and summarize the perioperative outcomes. The clinical and pathological data of five patients diagnosed with co-occurring DM and GC (DM-GC group) were retrospectively analyzed, who were admitted to the Department of Gastrointestinal Surgery at Ren ji Hospital, Shanghai Jiao Tong University, between January 2012 and April 2023. Their data were compared with 618 GC patients (GC-1 group) from September 2016 to August 2017 and 35 GC patients who were meticulously screened from 14,580 GC cases from January 2012 and April 2023. The matching criteria included identical gender, age, tumor location, TNM stage, and surgical procedure (7 GC patients were matched for each DM-GC patient). Analysis indicated that the DM-GC group comprised four female and one male patient. The female proportion was significantly higher (P = 0.032) than that of GC-1 group. In DM-GC group, four DM patients were diagnosed as GC within 12 months. One DM patients was diagnosed as GC within 15 months. Among them, four patients presented with varying degrees of skin rashes, muscle weakness while one patient had elevated CK levels as the typical symptom. Similarly, the preoperative tumor markers (CA-199 and CA-125) in the DM-GC group were significantly higher than normal levels (CA-199: 100 vs. 28.6%, P = 0.002; CA-125: 40 vs. 2.9%, P = 0.003) compared to GC-2 group. Moreover, postoperative complication incidence and the length of hospital stay were significantly higher in the DM-GC than GC-2 group [complication rate: 40 vs. 8.6%, P = 0.047; hospital stay: 15 days (range: 9-28) vs. 9 days (range: 8-10), P = 0.021]. GC Patients with dermatomyositis are more prone to experience postoperative complications and longer hospital stay.

Is There Any Relation Between High-Grade Prostate Cancer and Central Obesity, Hyperinsulinemia and Dyslipidemia?

Background: Prostate Cancer (PCa) is the sixth leading cause of cancer death in men, worldwide. Incidence of prostate cancer in India is on the rise. Most studies suggest that obesity has a positive correlation with a higher risk of developing high-grade PCa and dying of PCa. Central obesity and related biochemical alterations in terms of hyperinsulinemia and dyslipidemia are associated with severity of prostate cancer in terms of high Gleason score. Materials & Methods: Central obesity was assessed using anthropometric measurements including waist hip ratio (WHR) and body mass index (BMI). Serum PSA, testosterone, and insulin levels were estimated. Serum levels of triglycerides (TG), cholesterol, low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), high-density lipoprotein (HDL) were also measured. Standard staging procedures were followed and for histopathological evaluation of PCa, Gleason grading was done on core biopsy tissue. Results: In the present population-based study, persons with high Gleason score had significantly higher WHR supporting that central obesity may predispose to high-grade prostate cancer. Study has shown a significant relationship between high Gleason score and cholesterol, TG, VLDL, and low HDL levels; however no significant relation was found with LDL levels. Testosterone is a key prostate growth factor although PCa presents at an age when testosterone levels are declining. Conclusion: In this study, there was no significant difference in testosterone levels in patients with high and low Gleason scores. Keywords: Prostate, Cancer, High grade, Low grade

Risk and Timing of Venous Thromboembolism After Surgery for Lung Cancer: A Nationwide Cohort Study

BackgroundVenous thromboembolism (VTE) is a potentially preventable serious complication in patients with lung cancer undergoing thoracic operation. We examined the risk and timing of VTE after surgery for primary non-small cell lung cancer (NSCLC). MethodsAll patients undergoing operation for NSCLC in Denmark between 2003 and 2021 were identified in the Danish Lung Cancer Registry. VTE events in the year after operation were assessed by stage, patient characteristics, and surgical procedure. ResultsWe identified 13,197 patients who underwent operation for NSCLC in 2003 to 2021 (mean age, 67.6 years; 50% female); 10,524 (79.7%) had stage I-II NSCLC, and 2673 (20.3%) had stage III-IV. During 1-year follow-up, there were 335 VTE events, yielding a rate of 2.87 events/100 person-years and an absolute risk of 3.3% (95% CI, 2.3-4.0). VTE risk increased with advancing cancer stage (1.8% for stage I vs 3.9% for stage IV) but varied little by pathologic type, sex, and comorbidity level. Bilobectomy was associated with highest VTE risk (4.8%; 95% CI, 3.2-6.9), followed by pneumonectomy (3.5%; 95% CI, 2.3-5.0). The hazard of VTE was highest during the first 3 months after operation, after which it declined. For stage IV cancer, hazards increased again after 6 months. At 1 year, all-cause death was 12.6% (95% CI, 12.0%-13.1%). ConclusionsVTE developed in 3.3% of patients undergoing operation for NSCLC, most commonly within 3 months postoperatively. Prolonged thromboprophylaxis could be considered, particularly in those with advanced cancer stage and undergoing extended resections.

Pure Laparoscopic Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) for a Giant Hepatocellular Carcinoma (> 15 cm) Abutting the Liver Hilum

IntroductionThis video manuscript presents a unique case of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure performed in case of a giant hepatocellular carcinoma (> 15 cm in size) whereby both stages were completed via the pure laparoscopic approach. MethodsThis case was performed in our institution in 2022. All data were obtained from the patient’s records in our prospectively maintained database. Institutional Review Board (IRB) was not required for this publication. ResultsA 67-year-old Chinese male with a history of chronic hepatitis B infection presented with a giant liver mass. Magnetic resonance imaging (MRI) scan demonstrated a tumour, with features compatible with hepatocellular carcinoma, measuring 15.4 cm in maximal diameter in the right lobe of the cirrhotic liver with no distal metastasis. The indocyanine green (ICG) retention test at 15 min was prolonged at 25.5%, and the CT volumetry showed a borderline future liver remnant (FLR) volume of 692 ml or 22.9% (based on measured volume) and a standardized FLR of 49%. Stage 1 ALPPS was successfully completed via the pure laparoscopic approach. He was well post-operatively, and a repeat CT volumetry at 7 days showed an increase in FLR to 826 ml, and the ICG retention test improved to 18.1%. The patient underwent pure laparoscopic second-stage ALPPS, 8 days later. The patient recovered well with no liver decompensation or local complications. ConclusionThe use of MIS for in 2-stage ALPPS procedure for giant HCCs larger than 10 cm is technically feasible and safe when attempted in high-volume centres by experienced surgeons, while benefiting from the advantages of MIS liver resection.

Prevalence and Pattern of Nodal Metastases in Ovarian Malignancy: A Perioperative Audit

It is still unclear whether or not full nodal dissection and detailed staging offer any benefits. Little is known regarding the degree of nodal involvement based on histotype. We aimed to assess the lymphatic dissemination patterns and prevalence in early-stage epithelial ovarian cancer and identify the underlying risk factors for nodal metastases. This is a prospective study conducted over a period of three years. Institutional ethics committee approval has been obtained. A total of 157 consecutive patients with apparently early-stage ovarian cancer, who were treated at the Department of Gynecologic Oncology, Acharya Harihar Post Graduate Institute of Cancer (AHPGIC) from January 2020 to January 2023, were included. The most frequent grade was 3 (66.8%), and the most common histotype was high-grade serous ovarian cancer (HGSOC; 55.4%), followed by mucinous (16.5%) and endometrioid (14.01%) varieties. Seromucinous and clear cell ovarian cancers were found infrequently. The most common pattern was isolated pelvic nodal involvement in 48.9% of patients, followed by both para-aortic and pelvic nodal involvement in 25.5% of patients; 13 patients had isolated para-aortic nodal involvement. HGSOC was most commonly associated with isolated metastasis to the pelvic lymph nodes alone, while the endometrioid variety was prone to both pelvic and para-aortic spread. Out of the 55 patients with nonserous tumors, 12.72% exhibited nodal involvement. Most nonserous tumors showed affinity for both pelvic and para-aortic (42.85%) nodal metastases. Only grade 3 and serous histology showed a positive association with nodal metastasis. Approximately 45.2% of cases showed upstaging after surgical staging procedures. Multicentric studies are essential to analyze the prognostic impact of systematic lymphadenectomy in ovarian carcinoma patients, depending on the histotype and distribution pattern of nodal metastases.

Long-term outcome of minimally invasive staging surgery for clinical stage I endometrial cancer: A single institute experience in Taiwan.

Endometrial cancer is the most common gynecological cancer in developed countries. With recent advances in equipment and knowledge, minimally invasive surgery (MIS) is widely accepted for the treatment of endometrial cancer. This study had the largest number of cases to date in Taiwan, comparing outcomes between MIS and laparotomy staging surgery using real-world data with long-term follow-up. We retrospectively reviewed patients with clinical stage 1 endometrial cancer from 2009 to 2020 in our institute. All patients underwent comprehensive surgical staging procedures by MIS or laparotomy. The safety, morbidity, progression-free survival (PFS), and overall survival (OS) rates of the two groups were compared. Clinical and pathologic factors were compared with Chi-square and Fisher Exact test. PFS and OS were estimated by the Kaplan-Meier method. Differences between survival curves were analyzed using the log-rank test. A p value of <0.05 was considered statistically significant. Using Cox proportional hazards models, all factors found to be significantly associated with risk of recurrence on univariate analyses were then assessed together through multivariable models, resulting in a final oncologic outcome between MIS and laparotomy. A total of 665 cases (412 cases in MIS group and 253 cases in laparotomy group) were enrolled for data analysis. Median operation time was shorter in MIS group (244 and 265 minutes, p < 0.001). Median blood loss was also less (75 and 430 mL, p < 0.001). Median postoperative hospitalization duration was longer in the laparotomy group (2 and 7 days, p = 0.001). After adjusting presurgery risk factors, the PFS and OS were no significant difference in MIS and laparotomy groups. Using real-world data with long-term follow-up, we could confirm excellent PFS and OS in selective patients with clinical stage 1 endometrial carcinoma who received MIS, and the surgical time, hospital day, and blood loss were also less.

Outcomes of 1-Stage Versus 2-Stage Revisions After Hip Prosthetic Joint Infection

Background: Prosthetic joint infections (PJIs) are significant complications of total joint arthroplasties. The incidence of this dangerous complication is expected to rise, but there is not a unanimous solution. Two-stage surgical revisions are the traditional gold standard of treatment, but recent literature suggests that 1-stage revisions can be equally effective. A comparison of the outcomes of 2-stage revisions vs. 1-stage revisions has not been thoroughly investigated. This systematic review and meta-analysis were designed to compare the outcomes of 2-stage exchanges vs. 1-stage exchanges in the treatments of hip PJI based on comparison studies. Methods: MEDLINE, Embase, and Cochrane were searched for relevant studies that compared the effectiveness and outcomes of 1-stage and 2-stage procedures from January 2000 to May 2023. Keywords relating to hip PJI were used, and comparison studies of 1-stage vs. 2-stage procedures that reported patient characteristics and outcomes including success rates, rates of reinfection, or other outcomes such as functional outcomes (e.g., mean Harris hip scores), infection-free survival, and blood loss were included. Statistical analysis for this study was conducted using Review Manager 5.4 with a standard p-value of ≤ 0.05 for statistical significance. Results: Fifteen articles and 1,017 patients were included in the meta-analysis. One-stage revision procedures (320 patients) were found to have greater success rates (i.e., lower rates of reinfection) than 2-stage revisions (697 patients) (p = 0.04). One-stage revisions (184 patients) had shorter durations of operation and less blood loss than 2-stage revisions (90 patients) (p &lt; 0.05). Conclusion: One-stage revision procedures are associated with lower reinfection rates, blood loss, and durations of operation compared with 2-stage revisions. Level of Evidence: I.

This house believes that: MARI/TAD is better than sentinel node biopsy after PST for cN+ patients.

The increasing use and effectiveness of primary systemic treatment (PST) enables tailored locoregional treatment. About one third of clinically node positive (cN+) breast cancer patients achieve pathologic complete response (pCR) of the axilla, with higher rates observed in Human Epidermal growth factor Receptor (HER)2-positive or triple negative (TN) breast cancer subtypes. Tailoring axillary treatment for patients with axillary pCR is necessary, as they are unlikely to benefit from axillary lymph node dissection (ALND), but may suffer complications and long-term morbidity such as lymphedema and impaired shoulder motion. By combining pre-PST and post-PST axillary staging techniques, ALND can be omitted in most cN+patients with pCR. Different post-PST staging techniques (MARI/TAD/SN) show low or ultra-low false negative rates for detection of residual disease. More importantly, trials using the MARI (Marking Axillary lymph nodes with Radioactive Iodine seeds) procedure or sentinel lymph node biopsy (SLNB) as axillary staging technique post-PST have already shown the safety of tailoring axillary treatment in patients with an excellent response. Tailored axillary treatment using the MARI procedure in stage I-III breast cancer resulted in 80% reduction of ALND and excellent five-year axillary recurrence free interval (aRFI) of 97%. Similar oncologic outcomes were seen for post-SLNB in stage I-II patients. The MARI technique requires only one invasive procedure pre-NST and a median of one node is removed post-PST, whereas for the SLNB and TAD techniques two to four nodes are removed. A disadvantage of the MARI technique is its use of radioactive iodine, which is subject to extensive regulations.

Axillary Surgical Attitude Changing with Retrospective Application of ACOSOG Z0011 Eligible Criteria: An Institutional Evaluation.

Sentinel lymph node biopsy (SLNB) represents the gold standard for axillary surgical staging. The aim of this study was to assess the proportion of axillary lymph node dissection (ALND) that could be avoided after retrospective application of the ACOSOG Z0011 criteria and to evaluate the shortterm complications associated with axillary surgery. We reviewed breast cancer (BC) patients treated by primary breast-conserving surgery from 2012 to 2015. The percentage of SLNB vs ALND performed before and after the application of the ACOSOG Z0011 criteria was calculated. Complications were analyzed using crosstabs, with p<0.05 considered significant. Two hundred fifty one patients with a median age of 59.3 years were included. BC tumors had a median size of 13 mm and were mostly unifocal (83.9%). There were 30.3% with 1-2 metastatic lymph nodes (MLN). ALND was performed in 44.2%. The patients with 1-2 MLN, had only SLNB in 14.5% of cases. By applying the ACOSOG Z0011 criteria, ALND would have been avoided in 40.2% of patients. At least one postoperative complication was reported after SLNB or ALND for 45.7% and 74.7% of patients respectively. Seroma was the most frequent complication, and occurred in 29.3% of cases after SLNB and in 59.5% after ALND. SNLB is the most commonly used axillary surgical staging procedure in this series (55.8%). With a retrospective application of the ACOSOG Z0011 criteria in our population, ALND could have been avoided for 40.2% patients. Post-operative complications rate was higher after ALND, with a seroma rate at 59.5%.

Impact of Positive Cultures During the Second Stage of a Two-Stage Exchange: Systematic Review and Meta-Analysis

BackgroundTwo-stage exchange is a frequently performed procedure in patients who have a periprosthetic joint infection. Positive cultures when performing the second stage are perceived as a risk factor for reinfection. This study aimed to determine the impact of positive cultures during the second stage on the outcome of patients undergoing a 2-stage septic exchange and the impact of stopping the antibiotic treatment before reimplantation. MethodsWe systematically searched four databases. We performed a meta-analysis on the risk of complications after positive cultures during second stage and a subgroup analysis by antibiotic holiday period. We included 24 studies. ResultsFailure in the positive group was 37.0% and in the negative group was 13.7% with an odds ratio (OR) of 4.05. In the subgroup analysis by antibiotic holidays, failure rate without holidays was 15% and with holidays was 17.3% (P = .21). Failure in each group was higher when cultures were positive (without holidays, 25 versus 12.2%, P = .0003, and with holidays 41.1 versus 12.7%, P < .0001), but the risk of failure when cultures were positive was higher in the holiday group (OR 4.798) than in the nonholiday group (OR 2.225) in comparison to those patients who were culture negative at the second stage. ConclusionsMicrobiological eradication at second stage was not obtained in 18% of cases and it was associated with a higher failure rate. In patients with positive cultures, withholding antibiotic treatment was associated with lower failure rate. Further studies to define the antibiotic strategy in 2-stage exchange procedure are necessary.

Video-assisted thoracoscopic surgery for Andersson lesion in ankylosing spondylitis: A case report and literature review.

Andersson lesion (AL), a phenomenon initially described by Andersson nearly 80 years ago, has been the subject of extensive research and various treatment modalities. The ongoing debate surrounding the need for anterior surgery in AL cases has spurred numerous proposed approaches. Despite the demonstrated efficacy of anterior surgery in achieving fusion and stabilization, its implementation is associated with prolonged operation time and heightened intraoperative bleeding. A 32-year-old male patient presented at our hospital in February 2019 with a 2-month history of bilateral lower extremity weakness and sensory disturbances. These symptoms were exacerbated by a recent fall. AL conbined with ankylosing spondylitis. A 1-stage posterior fixation and decompression procedure was performed to ensure spinal stability, minimize deformities, and reduce surgical trauma. To achieve these goals, a 2-stage approach was employed, which included video-assisted thoracoscope-guided vertebrectomy, spinal canal decompression, and bone graft fusion. No recurrences of significant pain, limb numbness, or other symptoms were reported, ultimately leading to an improved quality of life for the patient. We utilized video-assisted thoracoscopic surgery technology for anterior bone graft fusion in a patient with AL to minimize the trauma of secondary surgery. However, the 3-year follow-up showed insufficient bony fusion at the fracture site. Nevertheless, the patient maintained spinal stability with posterior internal fixation and no significant kyphosis or symptoms. Thus, standalone posterior fixation may suffice for favorable clinical outcomes in patients with AL.

Effect of temperature and time on hydrothermally synthesized nitrogen-doped graphene

Graphene attracts attention due to its high surface area and its great electrical, optical, and mechanical properties. Studies about graphene have been conducted to develop synthesis methods and to determine the effects of synthesis parameters on productivity and properties. In recent years, studies have focused on doping graphene with foreign atoms to improve its properties. Nitrogen (N) is of interest among doping materials because it increases graphene’s electrocatalytic activity and electrochemical performance. In this study, the production of nitrogen-doped graphene was studied, and a 2-stage synthesis procedure was used. In the first stage, graphene oxide was obtained from graphite by using the Modified Hummers method. To obtain N-doped graphene (N-graphene) from synthesized graphene oxide, N doping and hydrothermal method were used in the second stage. To determine the effect of temperature and time on the hydrothermal production of N-graphene from graphene oxide, 3 different temperatures and 3 different times were studied. Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction analyses, and the Debye-Scherrer equation indicated that nitrogen-doped graphene was obtained. The effects of temperature and time on synthesizing N-graphene were discussed within the scope of the parameters used in the hydrothermal method.

Treatment of infected bone defects with the induced membrane technique.

This study aimed to evaluate the effectiveness of the induced membrane technique for treating infected bone defects, and to explore the factors that might affect patient outcomes. A comprehensive search was performed in PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases between 1 January 2000 and 31 October 2021. Studies with a minimum sample size of five patients with infected bone defects treated with the induced membrane technique were included. Factors associated with nonunion, infection recurrence, and additional procedures were identified using logistic regression analysis on individual patient data. After the screening, 44 studies were included with 1,079 patients and 1,083 segments of infected bone defects treated with the induced membrane technique. The mean defect size was 6.8 cm (0.5 to 30). After the index second stage procedure, 85% (797/942) of segments achieved union, and 92% (999/1,083) of segments achieved final healing. The multivariate analysis with data from 296 patients suggested that older age was associated with higher nonunion risk. Patients with external fixation in the second stage had a significantly higher risk of developing nonunion, increasing the need for additional procedures. The autografts harvested from the femur reamer-irrigator-aspirator increased nonunion, infection recurrence, and additional procedure rates. The induced membrane technique is an effective technique for treating infected bone defects. Internal fixation during the second stage might effectively promote bone healing and reduce additional procedures without increasing infection recurrence. Future studies should standardize individual patient data prospectively to facilitate research on the affected patient outcomes.

Diagnostic performance of additional imaging tests for staging purposes in a bicentric German series of low-risk early breast cancer patients

PurposeLow-risk early breast cancer rarely leads to the development of metastatic disease, and in these patients, additional imaging test is controversial. The aim of our study was to evaluate the conventional staging procedures in a bicentric German series of low-risk breast carcinoma patients.MethodsRetrospective evaluation of all patients diagnosed with early, low-risk breast cancer at Saarland University Hospital and Freiburg University Hospital in 2017 was performed. Clinical patient characteristics, the number and type of additional imaging examinations, follow-up examinations, and results were evaluated. The detection rate of metastases and the rate of false-positive findings were analyzed.ResultsA total of 203 patients were included, with all patients received at least one additional imaging test. Initially, a total of 562 additional imaging examinations were performed: 166 chest X-rays, 169 upper abdominal ultrasounds, 199 bone scans, 27 computer tomographies (CT) chest and abdomen, and 1 CT abdomen. 6.8% of patients had abnormal findings reported, requiring 38 additional imaging examinations. One patient (0.5%) was found to have bone metastases. The rate of false-positive findings in the performed additional imaging procedures was 6.6%.ConclusionMetastatic disease was detected in one of 203 patients with low-risk early breast cancer. A total of 562 examinations and additional 38 follow-up examinations were performed without detection of metastasis (this corresponds to approximately 3 examinations/patient). The rate of false-positive findings was 6.6%. The performance of additional imaging procedures for detection of distant metastases should be critically reconsidered in patients with low-risk early breast cancer.

Prefabricated venous flap, an advanced free venous flap for distant transfer: An experimental rat study

Abstract Background Arterialized venous flap can improve the survival of traditional free venous flap. Arterialized venous flaps are, however, still not popularly selected as the first choice for microsurgical reconstruction because of its nutrient insufficiency. Materials and Methods Eighty-four Lewis rats (10–12 weeks old, 350–400 g) were used. Left hemivertical chest-and-abdominal skin flap (4 × 14 cm2) was the experimental model. Five protocols were designed and performed: protocol I (n = 18), nutrition territory study; protocol II (n = 18), immediate A-V anastomosis; protocol III (n = 12), prefabricated venous flap (PFVF) transformed from pedicle-based skin flap; protocol IV (n = 18), PFVF transformed from perforator-based skin flap; and protocol V (n = 18), PFVF transformed from capillary-based skin flap. The all transformed PFVFs had a 2-week delay procedure from the original skin flaps. Results The hemivertical chest-abdomen skin flap contains 3 nutrient vessels: superior, inferior, and midabdominal. The PFVF coming from the perforator-based skin flap showed significantly superior than other 2 methods with the best survival rates after arterialization, followed by the capillary-based skin flap and then the pedicle-based skin flap. Conclusions The PFVFs after delay procedure and arterialization have been proved to greatly increase the flap survival than traditional free venous flap. Delay procedure has benefits for the transformation from the nutritional skin flaps into PFVFs, which is especially true in perforator-based skin flaps. Such transformation is a 2-stage procedure. Prefabricated venous flaps might offer a “last case scenario” surgery as an option to reconstruct wound defects where no other suitable skin flaps are available. Further investigation is warranted.

Decannulation in Revision Pediatric Laryngotracheal Reconstruction.

To evaluate how patient characteristics and surgical techniques influence the rate of and time to decannulation after pediatric revision laryngotracheal reconstruction. The study was a retrospective cohort investigation of children with a history of laryngotracheal stenosis treated between 2008 and 2021 with revision open airway surgery. The primary outcome evaluated was decannulation. The secondary outcome analyzed was time to decannulation. Thirty-nine children were included in the study with median age 49 months; 61.5% were male. Children undergoing single stage revision surgery were far more likely to be decannulated (OR 6.25, 95% CI 1.33-45.97, p = 0.0343). Rolling logistic regression of the probability of decannulation stratified by time between open surgeries demonstrated significantly decreased chance of decannulation with reoperation within 6 months. Children managed with anterior/posterior grafting compared with a single graft were observed to have an increased time to decannulation, (HR 0.365, 95% CI 0.148-0.899, p = 0.005, Log-Rank). We observe that in the case of revision pediatric open airway surgery, chance of decannulation is improved when surgery is performed in a single stage as well as 6 months after the most recent procedure. Patients and families should be counseled that complex stenosis requiring double stage procedures or anterior/posterior grafting is associated with a decreased probability of decannulation and increased postoperative time with a tracheostomy, respectively. 4 Laryngoscope, 134:1926-1932, 2024.

Comparative Study between Laparoscopic Single Anastomosis Sleeve Ileal Bypass (SASI Bypass) versus Laparoscopic Mini-Gastric Bypass (MGB/OAGB) in Controlling Type 2 Diabetes in Morbidly Obese Patients

Abstract Background In our opinion, the most important criteria in the selection of a bariatric procedure remain the safety and efficacy in achieving both weight loss and remission of the metabolic consequences of obesity. Despite the intrinsic limitation imposed by a retrospective study, our results seem to confirm that LMGB is both safe and effective for the treatment of morbidly obese diabetic patients. Laparoscopic SASI bypass has been shown to be an effective, safe, and simple procedure for the treatment of morbid obesity and its associated metabolic consequences. Moreover, it results in minimal postoperative nutritional complications in comparison to other bariatric procedures. However, long-term follow-up period should be performed to evaluate postoperative weight loss, metabolic changes, and nutritional status of patients. Objective To compare Laparoscopic Single Anastomosis Sleeve Ileal (SASI) Bypass with Minigastric bypass (MGB/OAGB) in controlling type 2 Diabetes Mellitus in morbidly obese patients. Patients and Methods This study is a retrospective comparative study in which morbidly obese Patients with type 2 DM who underwent either Mini-gastric bypass or Single Anastomosis Sleeve Ileal (SASI) bypass with available preoperative Fasting blood Glucose, Hemoglobin A1c&amp; serum cpeptide (As predictive measures for remission of diabetes after surgery) was collected &amp; their data and results was compared to this1,3, 6 &amp; 12 months postoperatively. Results As regard glycemic and lipid profile pre and postoperative mean values in MGB group, the present study showed that there were significant differences between before and after surgery as regard FBG, HbA1C, triglyceride, cholesterol, HDL and LDL. Laparoscopic mini-gastric bypass (MGB) is a technically simple and safe procedure in SSO patients. LMGB has the advantages of being a single stage procedure, being easily reversible and revisable in a laparoscopic procedure and does not sacrifice portions of the stomach or implant foreign materials. SASI bypass is a promising operation that offers excellent weight loss and metabolic result. The elimination of two ways for passage of food and one anastomosis decrease nutritional deficiency and the possibility of surgically related complications. Conclusion Metabolic surgery is a safe option for carefully selected patients with metabolic syndrome. The increased risk for type 2 diabetes and cardiovascular disease demands therapeutic attention for those at high risk. Our study suggests that both SASI and MGB are highly effective in controlling Diabetes mellitus, Hypertension and Hyperlipidemia.

WTP3.4 Improvement of biliary service in hospital by altering the management of suspected or confirmed bile duct stones. Confirmed bile duct stones can be managed by single-stage procedure of laparoscopic cholecystectomy (LC) plus common bile duct exploration (CBDE). Intra-operative cholangiogram (IOC) can be used to avoid delays waiting for MRCP

Abstract Background Significant delays can follow the process of emergency admissions with biliary problems in hospitals. Routine pathway for gallstones and abnormal liver functions tests (LFTs) is ultrasound (US) followed by MRCP. Pathway for confirmed common bile duct (CBD) stones has been routinely an ERCP followed by LC either as inpatient or outpatient. Significant delays take place awaiting MRCP considering that there is no out-of-hours or weekend service, while ERCP lists only occur twice weekly for both emergency and elective which can lead to unnecessary delays. Methods An audit was performed for 2 months period from 1st October 2022 to 30th November 2022 to assess how patients were managed in the department. Results A total of 16 emergency LCs were done in this period. 3 of them had ERCP prior to operation while 5 had MRCP prior to exclude CBD stones. Average length of stay (LOS) for these 8 patients was 7 days. It was estimated that LOS for these patient would have been reduced to 4 days if IOC +/- CBDE were done. A total of 37 ERCPs were done in the same period. 22 of them were done as emergency of which 12 were for CBD stones, 7 for cancers and 3 for bile leak. 7 of the 12 emergency ERCPs for CBD stones would have benefited from one stage procedure of LC + CBDE reducing their LOS and leaving space for other cases in ERCP lists. Conclusion A dedicated weekly IOC/CBDE list was proposed to overcome this problem.
