Surgery Case Reports最新文献

Colonic lipomas are a benign tumor that can present in multiple ways, including; incidentally, abdominal pain, change in bowel habit, bleeding, intestinal obstruction and intussusception. We present the case of a 48-year-old gentlemen who presented to the emergency department with a 3 day history of abdominal pain and was found to have a 5 cm intramural ischemic pedunculated colonic lipoma causing intussusception and large bowel obstruction. He received initial management with emergency laparoscopic exploration, reduction of intussusception, colotomy and lipoma excision. He made a full recovery. The current approaches to management of colonic lipomas are conservative, endoscopic or surgical. This case highlights the potential consequences of untreated colonic lipomas. In our review of the literature, we highlight that there is a lack of clear consensus on appropriate management of these patients.

Osteosarcoma is a classical malignant bone-forming neoplasm, characterised by osteoid synthesis by malignant osteoblasts. Osteosarcomas have an aggressive clinical course with a high mortality rate, despite their relatively low risk of distant metastases. The jaw bone is the most common site of occurrence in the head and neck region. These neoplasms often show characteristic clinical behaviours, varied radiological appearances, and a wide-ranging histological growth pattern. Early diagnosis and radical surgery, followed by radiotherapy and chemotherapy if required, have been the treatment of choice. This case report emphasises the importance of early diagnosis of this tumour based on clinical features, radiographic examination, and confirmation by histopathology. Confirmation of the final diagnosis of osteosarcoma often requires a histopathological examination of the multiple biopsy specimens. Adjuvant chemotherapy followed by radical surgery resulted in an excellent prognosis in the present case. Considering the rarity of the neoplasm, its fast progression, and its aggressiveness, the present case report would contribute to a better understanding of osteosarcomas involving the jaw bone and the management of the tumour involving the central arch of the mandible with involvement of the adjacent soft tissue structures.

Background

Mucormycosis is a severe fungal infection manifested mostly in immunocompromised hosts. Underlying causes for Mucormycosis include uncontrolled diabetes mellitus (DM), malignancies, chronic corticosteroid use, and organ transplant.

Case report

a 57-year-old Caucasian female, with insulin-dependent DM, presented to otolaryngology casualty complaining about a severe headache and nasal discharge. Clinical, laboratory, imaging, and histopathological investigations confirmed the diagnosis of Mucormycosis due to uncontrolled DM. Mucormycosis was managed pharmacologically, surgically, and by improving glycemic control. Psychological factors leading to non-adherence to insulin therapy were investigated and psychiatric evaluation and counseling were emphasized.

Practical implications

Healthcare providers should be aware of the signs, symptoms, and underlying causes of Mucormycosis and should manage it promptly. Mental health status should be part of the patient's evaluation and treatment plan.

Introduction

Laparoscopic sleeve gastrectomy (LSG) is a procedure that is being increasingly recommended. However, LSG can worsen gastroesophageal reflux disease (GERD) and cause vomiting, and consequently impact the quality of life (QOL) of patients. Abnormal motility of the sleeve gastric tube has been linked to the onset of GERD and vomiting. Hence, this study investigated the peristalsis of the sleeve gastric tube after LSG and its relationship with gastroesophageal reflux. There are only a few reports on the peristalsis of the sleeve gastric tube after LSG.

Methods

We measured the motility function of the sleeve gastric tube using high-resolution manometry (HRM) within 2–4 weeks after LSG. The manometry catheter was positioned in the antrum using fluoroscopy.

Results

This analysis included 18 patients. Postoperative HRM measurement of the sleeve gastric tube was characterized by the absence of gastric body peristalsis in at least 90% of swallows and contractions of the antrum. Furthermore, reverse peristalsis was observed from the pyloric antrum toward the stomach body although the frequency was low.

Conclusions

LSG was associated with characteristic of pressure and peristalsis in sleeve gastric tube. HRM was able to detect and visualize intragastric pressure and peristalsis of the sleeve gastric tube.

Objectives

The stapled suture is used to close the aortic stump during surgery for abdominal aortic infection. The current study aimed to investigate the short- and long-term outcomes of stapled closure of the aortic stump with axillo-bifemoral (AxBF) bypass grafting.

Methods

The short- and long-term outcomes of 11 patients who underwent surgery for abdominal aortic infection were retrospectively analyzed.

Results

Of 11 patients, 7 underwent stapled closure of the aortic stump with AxBF bypass grafting, and four underwent other reconstructive procedures with no aortic stump. Four patients (three who underwent stapled closure of the aortic stump and one who underwent other reconstructive procedures without the aortic stump) had operative death. However, none of the patients had aortic stump blow-out during the same hospitalization for surgery. The 1- and 5-year survival rates of the patients who underwent stapled closure of the aortic stump with AxBF bypass grafting were 57% and 29%, respectively. One patient developed aorto-duodenal fistula at 32 months after surgery. The patient survived for 12 months until bleeding in the recurrent aorto-enteric fistula occurred.

Conclusion

Stapled closure of the aortic stump is durable. The use of a linear stapler is a useful technique for reinforcing the aortic stump in patients who underwent excision of an infected abdominal aortic aneurysm or an infected abdominal graft.

Acute emphysematous suppurative thyroid abscess is a potentially life threatening uncommon disease caused most commonly by gram positive organisms. It usually occurs in immunocompromised individuals with pre-existing multinodular goiter secondary to hematogenous spread of infection. The most characteristic feature of this disease is the presence of gas within the thyroid swelling seen on imaging, even though crepitus may be absent on examination. Surgical debridement and thyroidectomy are the procedure of choice in such cases and can lead to effective cure. We present an unusual and rare case of an acute emphysematous suppurative thyroid abscess caused by a gram negative (non-clostridial) organism in an immunocompromised patient after a fine needle aspiration cytology intervention.

Introduction

Extraskeletal osteosarcomas are rare tumors with poor overall survival and a high propensity for recurrence. It frequently arises in the lower extremities and has been reported to metastasize commonly in the lungs. Controversy exists as to whether it should be treated as a soft tissue sarcoma or an osteosarcoma. Various adjuvant treatment approaches have also been studied with conflicting results.

Case report

We present a 73-year-old female with a painless, gradually enlarging right upper arm mass for 2 months. She previously underwent a left mastectomy 5 years ago for a stage II breast cancer. Preoperative imaging showed a resectable, heterogenous right upper arm mass. She subsequently underwent radical excision with frozen section revealing spindle cell neoplasm. Final histopathology was consistent with extraskeletal osteosarcoma. The patient remains disease-free as of most recent follow-up.

Discussion

There are several proposed mechanisms for extraskeletal osteosarcomas. Based on the history and location of the tumor, we initially thought that this was metastatic breast cancer. Preoperative imaging determines resectability and surgical approach. Radical surgery is frequently performed which largely depends on the site of the tumor. Complete primary resection with adequate margins remains to be the treatment of choice to prevent recurrence or metastasis. The role of adjuvant radiotherapy or chemotherapy is still to be established.

Conclusion

This case highlights the various treatment options and the need for further research on its clinical behavior and potential targeted therapies.

We present the case of a patient with unexplained postural headaches who was found to have an atraumatic Cerebrospinal Fluid (CSF) leak from the foraminal and extraforaminal epidural spaces at the levels of C5-C6, C6-C7, C7-T1, and T1-T2, with contrast tracking along the brachial plexus elements as well as the bilateral scalene and paraspinal musculature. This is a rare presentation as the etiology was not connected to brachial plexus injury or surgical trauma but rather was a spontaneous occurrence. The patient was successfully treated with a CT-guided epidural blood patch that conferred complete resolution of the symptoms. We hope this case study offers clinical utility with the diagnosis and management of patients with orthostatic headaches.

Introduction

The anterior component separation (ACS) is a technique used for abdominal wall closure performed by dissecting and medially advancing the musculature to achieve tension-free closure.

Methods

and Materials:

This study reviewed our experience with this procedure as used for complex abdominal wall defects encountered during colorectal surgery in a 7-year period.

Results

Sixteen patients were included, with 12 having malignancies and the rest for infectious or inflammatory conditions. Defects ranged from 16–400 cm² and were mostly located at the midline (56%, n = 9). Five cases required additional flaps for closure, attributed either to the size or area of abdominal involvement where benefits of component separation is more limited. Complications include surgical site infection (n = 4), hematoma (n = 2), seroma (n = 1), and wound dehiscence (n = 2). None required ICU admission or assisted ventilation post-operatively. One patient died who had a preexisting cardiac pathology, and the rest were discharged improved.

Conclusion

This study demonstrates use of this modality for autologous reconstruction of complex appropriately sized abdominal wall defects from multiple etiologies. Adjunct flaps may be used to achieve reconstruction particularly in areas wherein the effectiveness of ACS is limited. While the study is able to describe immediate outcomes, long-term follow-up is recommended.

Background

Understanding the risks of performing open-heart surgery in patients with cirrhosis is of critical importance given increased risks of morbidity and mortality. We analyzed the variables and risk scoring systems associated with survival and postoperative outcomes among patients with cirrhosis after open-heart surgery.

Methods

This is a single-center retrospective study of 32 patients with cirrhosis who underwent open-heart surgery at our institution between August 2020 – September 2022. Patients were stratified by mortality status to compare demographic and clinical variables. Survival was assessed using Kaplan-Meier curves and log-rank tests for the following variables: Model for End-Stage Liver Disease (MELD) score (<11 vs ≥11), Child-Turcotte-Pugh (CTP) class (A vs B vs C), Society of Thoracic Surgeons (STS) score (predicted mortality <4 vs 4 to 8 vs ≥8), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II (<3.3 vs ≥3.3), and cardiopulmonary bypass (off pump vs on pump).

Results

Overall survival for our patient cohort was 93.8% at 30 days, 81.3% at 1 year, and 78.1% at 2 years postoperatively. Increased preoperative creatinine (p = 0.049), preoperative total bilirubin (p = 0.017), intraoperative blood products (p = 0.016), and intensive care unit length of stay (p = 0.001) were significantly associated with decreased survival. Among the risk scoring systems, only CTP class was significantly associated with survival (p < 0.0001).

Conclusions

We demonstrated high short-term and long-term survival among patients with cirrhosis after open-heart surgery, suggesting that select patients may be operative candidates. Among risk-scoring systems, only CTP was significantly associated with survival, which may guide future risk stratification strategies.
