Factors Associated with the Occurrence and Healing of Umbilical Pilonidal Sinus: A Rare Clinical Entity

Intraoperative and Postoperative Outcomes of Modified Bidirectional Intra-Umbilical Incision versus Infra-Umbilical Incision for Direct Trocar Insertion in Gynaecological Laparoscopy: A randomised controlled trial

Objectives

This study aimed to describe a modified, curved, deep, bidirectional, intra-umbilical, vertical incision for primary trocar insertion and prospectively compare its intraoperative and postoperative outcomes with an infra-umbilical incision in gynaecologic laparoscopy.

Methods

Between August 2019 and March 2021, 110 patients subjected to the direct trocar insertion technique for laparoscopic intervention were classified into two groups. Group A comprised 55 cases of infra-umbilical incision, whereas group B comprised 55 cases of a modified, curved, longitudinal, deep, bidirectional, intra-umbilical incision. Afterwards, intraoperative and postoperative assessments were performed.

Results

The increase in the numbers of parity, gravidity and previous caesarean sections was found to be statistically significant; a smaller number of infertility complaints were observed in group B. Similarly, group B expressed a statistically significant less peri-trocar CO2 leakage (46 [83.6%] patients versus 28 [50.9%] patients) and more tightness of the primary portal entry (45 [81.8%] patients versus 30 [54.5%] patients) when compared to group A throughout the whole operation. After a one-month follow-up, a statistically significant (P = 0.029) decrease in the Observer Scar Assessment Scale and Patient Scar Assessment Scale scores in group B (10.4 ± 4.2 and 11.8 ± 4.3, respectively), demonstrating better cosmoses when compared to group A (13.3 ± 5.7 and 16.0 ± 6.8, respectively).

Conclusion

Performing a modified, curved, deep, bidirectional, intra-umbilical, vertical incision for the insertion of a primary laparoscopic trocar (i.e. Darwish laparoscopic entry) is a simple and fast step that results in the elimination of intraoperative gas leakage and trocar slippage without the need for any additional sutures. Aesthetically, it results in a better scar with satisfactory cosmoses when compared to an infra-umbilical incision.

Drug Distribution and Penetration of Foam-Based Intraperitoneal Chemotherapy (FBIC)

For decades, intraperitoneal chemotherapy (IPC) was used as a liquid solution for the treatment of peritoneal metastasis. Due to its advantageous physical properties, foam-based intraperitoneal chemotherapy (FBIC) was recently proposed as a treatment for peritoneal metastasis. For the first time, this study intends to examine the feasibility, expansion, drug distribution, and penetration of FBIC in vivo. Three swine received contrast-enhanced FBIC doxorubicin delivered using a bicarbonate carrier system. During the procedure, intraoperative blood analyses and periumbilical diameter, as well as foam distribution, penetration, and expansion of the FBIC were analyzed. The swine received an abdominal CT scan to evaluate the contrast distribution. Furthermore, a hematoxylin-eosin (HE) staining of peritoneal samples was performed, and fluorescence microscopy was conducted. FBIC was performed without complications. The periumbilical diameter peaked after 5 min and then decreased. Blood analyses showed changes in blood parameters, with a reduction in the pH levels of serum calcium and potassium. CT scan detected contrast-enhanced FBIC throughout the abdominal cavity. Fluorescence microscopy confirmed that all areas were exposed to doxorubicin and no pathologies were detected in the HE histology. Our preliminary results are quite encouraging and indicate that FBIC is a feasible approach. However, in order to discuss possible clinical applications, further studies are required to investigate the pharmacologic, pharmacodynamic, and physical properties of FBIC.

Treatment and Management Experience of Idiopathic Granulomatous Mastitis in a Low-income Country

OBJECTIVE

 Reporting our experience of the management and treatment of Idiopathic granulomatous mastitis (IGM) in a low-income country by describing patients characteristics and therapy with emphasis on conservative surgical excision and postoperative care as the cornerstone of treatment.

METHODS

 A retrospective cohort of women with histopathological diagnosis of IGM from 2014 to 2018 at Instituto Nacional Materno Perinatal in Lima, Peru. Patients' characteristics, clinical presentation, treatment, management, postoperative care, and follow-up were analyzed.

RESULTS

 Thirty-eight patients with histopathological diagnosis of IGM were identified. Their average age was 35.9 years and 23 (60.5%) reported previous use of hormonal contraceptives. Nine (23.7%) patients had chronic mastitis with previous treatment. The time from the onset of symptoms to the first clinic consult was 5.1 months on average. Twenty-one (55.3%) patients had the lesion in the right breast, with a mean size of 6.9 cm. Conservative surgical excision was performed in all patients. Additionally, 86.8% required corticosteroids and 78.9% were treated with antibiotics. Complete remission was obtained at 141 days on average (range 44 to 292 days). Six (15.8%) women reported ipsilateral recurrence and 5 (13.2%), contralateral. The latency time was 25.5 months on average.

CONCLUSION

 The conservative surgical treatment demonstrated and close follow-up made for a high cure rate, but with recurrence similar to that reported in the literature. Use of gloves is an alternative to manage post operative wounds in a low-income country. The most frequent adverse effect was breast surgical scar.

CCND2 and miR-206 as potential biomarkers in the clinical diagnosis of thyroid carcinoma by fine-needle aspiration cytology

BACKGROUND

To investigate the relationship between cyclin D2 (CCND2) and miR-206 expression in fine-needle aspiration cytology of thyroid carcinoma.

METHODS

A total of 65 patients with thyroid carcinoma were selected as the subjects and 65 patients with benign thyroid nodules were in control group. The fine-needle aspiration cytology of thyroid nodules was performed. CCND2 and miR-206 levels were detected by PCR.

RESULTS

Compared with the patients with benign thyroid nodules, the expression level of miR-206 in fine-needle aspiration cytology of thyroid cancer patients decreased significantly and the expression level of CCND2 increased significantly. CCND2 and miR-206 expression was negatively correlated in thyroid cancer tissues. Area under curve (AUC) of miR-206 level in the diagnosis of thyroid cancer was 0.889, and the sensitivity and specificity were 92.3% and 81.5%, respectively. AUC of CCND2 level in the diagnosis of thyroid cancer was 0.837, and the sensitivity and specificity were 67.7% and 89.2%, respectively. The AUC of combined detection of CCND2 and miR-206 in the diagnosis of thyroid cancer was 0.959, and the sensitivity and specificity were 93.8% and 87.7%, respectively. The levels of miR-206 and CCND2 were significantly correlated with TNM staging and lymph node metastasis.

CONCLUSIONS

miR-206 and CCND2 may become new biomarkers for clinical diagnosis of thyroid cancer based on the fine-needle aspiration cytology of thyroid nodules.

The Role of Thromboprophylaxis in Patients with Portal Vein Thrombosis: A Life-Threatening Complication after Laparoscopic Sleeve Gastrectomy Following 8 Years of Experience in a Bariatric Center of Excellence

Porto-mesenteric vein thrombosis (PVMT) is a rare but life-threatening complication after laparoscopic sleeve gastrectomy (LSG). Laparoscopic sleeve gastrectomy (LSG) is considered the most common procedure for efficiently realizing weight loss and treating obesity-related co-morbidities. This study aimed to shed light on this relatively rare complication by presenting a series of patients who developed PMVT after LSG in light of the need to change the specific protocol of thromboprophylaxis in bariatric patients. We proposed to answer two questions: whether we should perform a thrombophilia workup as a standard practice and whether we should extend chemoprophylaxis to more than 3 weeks among all bariatric patients. This study also aimed to investigate the possible risk factors and eventually present our updated protocol for PMVT management and prophylaxis.

Endofibrosis as a Causative Agent of the Peripheral Artery Disease: A Report of Two Cases for Professional Cyclists

Endofibrosis is a rare disease that predominantly affects athletes and is caused by a gradual occlusion of the (usually iliac) artery due to a thickening of the intima. From our experience, we report in this article two cases with the entity of endofibrosis in females around 30 years old. The first case presented with acute limb ischemia, and the second one was with pain in the leg during exercise. In addition, both cases are professional cyclists. They were eventually diagnosed with endofibrosis and underwent surgical procedures. They are now pursuing their professional career successfully. Last but not least, endofibrosis might be classified as an occupational disease, particularly, in the case of professional athletes or cyclists.
