Port-Site Metastases and Chimney Effect of B-Ultrasound-Guided and Laparoscopically-Assisted Hyperthermic Intraperitoneal Perfusion Chemotherapy

Multidisciplinary team diagnosis and treatment of pancreatic cancer: Current landscape and future prospects

The pathogenesis of pancreatic cancer has not been completely clear, there is no highly sensitive and specific detection method, so early diagnosis is very difficult. Despite the rapid development of tumor diagnosis and treatment, it is difficult to break through in the short term and the overall 5-year survival rate of pancreatic cancer is less than 8%. In the face of the increasing incidence of pancreatic cancer, in addition to strengthening basic research, exploring its etiology and pathogenesis, it is urgent to optimize the existing diagnosis and treatment methods through standard multidisciplinary team (MDT), and formulate personalized treatment plan to achieve the purpose of improving the curative effect. However, there are some problems in MDT, such as insufficient understanding and enthusiasm of some doctors, failure to operate MDT according to the system, lack of good communication between domestic and foreign peers, and lack of attention in personnel training and talent echelon construction. It is expected to protect the rights and interests of doctors in the future and ensure the continuous operation of MDT. To strengthen the research on the diagnosis and treatment of pancreatic cancer, MDT can try the Internet +MDT mode to improve the efficiency of MDT.

Comparison of surgical smoke between two approaches for endoscopic thyroidectomy and open thyroidectomy

BACKGROUND

Surgical smoke has been recognized as a potential health risk by an increasing number of researchers. Moreover, the counts of surgical smoke produced during different surgical approaches are different. This study aimed to measure and compare the particulate matter (PM) of surgical smoke generated during open thyroidectomy and two endoscopic approaches for thyroidectomy to provide guidance for safe clinical practices.

METHODS

Forty-eight patients with thyroid cancer admitted to our hospital from June 2020 to December 2021 and treated with different surgical approaches were enrolled in this study. The total and peak counts of PM, dynamic changes, and other characteristics of surgical smoke produced during surgery were recorded. PM was classified as PM_2.5 (size ≤ 2.5 μm) and PM₁₀ (size ≤ 10 μm).

RESULTS

In a single cut, both the peak and total counts of PM_2.5 and PM₁₀ of surgical smoke in the open thyroidectomy group (n = 15) were significantly higher than those in the breast approach endoscopic thyroidectomy with CO₂ insufflation group (n = 15) and the gasless transaxillary endoscopic thyroidectomy group (n = 18) (p < 0.001). Moreover, the latter two groups showed no significant differences in the peak and total counts of PM_2.5 and PM₁₀ (p > 0.05).

CONCLUSION

In thyroid surgery, more surgical smoke is produced during open thyroidectomy than during endoscopic thyroidectomy, while different endoscopic approaches showed no significant difference in surgical smoke production. Thus, endoscopic approaches outperform the open thyroidectomy approach with regard to surgical smoke production.

Laparoendoscopic Single Site Surgery for the Treatment of Huge Ovarian Cysts Using an Angiocatheter Needle

PURPOSE

The aim of this study was to evaluate the feasibility and safety of laparoendoscopic single site (LESS) surgery using an angiocatheter needle in patients with huge ovarian cysts (diameter ≥15 cm).

MATERIALS AND METHODS

Thirty-one patients with huge ovarian cysts underwent LESS surgery using an angiocatheter needle between March 2011 and August 2016. An intra-umbilical vertical incision (1.5-2.0 cm) was made in the midline. After the cyst wall was punctured using an angiocatheter needle, the fluid contents were aspirated with a connected vacuum aspirator. After placing a Glove port in the umbilical incision, LESS surgery was performed using a rigid 0-degree, 5-mm laparoscope and conventional, rigid, straight laparoscopic instruments. Knife-in-bag morcellation was instituted for specimen collection.

RESULTS

The median maximal diameter of ovarian cysts was 18 cm (range, 15-30 cm), the median operation time was 150 minutes (range, 80-520 minutes), and the median volume of blood loss was 100 mL (range, 20-800 mL). Three patients (9.7%) were diagnosed with malignant ovarian cancer using intraoperative frozen examination, and 1 patient was converted to laparotomy due to advanced disease. Thirty patients underwent LESS, and there was no need for an additional laparoscopic port.

CONCLUSION

LESS surgery using an angiocatheter needle, with leaving only a small postoperative scar, was deemed feasible for the management of huge ovarian cysts.

Secondary pregnancy by an implant in a laparoscopic trocar site: A case report

RATIONALE

For nearly 20 years, laparoscopy has been generally regarded as the gold standard for the surgical treatment of ectopic pregnancy and its application is very widespread. According to our knowledge, secondary pregnancy at the laparoscopic trocar site has not yet been reported until now.

PATIENT CONCERNS

A 24-year-old Chinese female patient is reported herein. Her left fallopian tube was removed via laparoscopy due to a first ectopic pregnancy. Her postoperative blood β-human chorionic gonadotropin (β-hCG) was increasing with irregular vaginal bleeding. The patient was initially regarded as having an old ectopic pregnancy.

DIAGNOSES

Secondary pregnancy by an implant in a laparoscopic trocar Site.

INTERVENTIONS

Because of secondary pregnancy at the laparoscopic port site, laparoscopic surgery was performed again 32 days after the first operation. Approximately 1000 milliliters (mL) of free intraperitoneal hemorrhage and active bleeding of the lesion were detected. Histopathologic examination confirmed the lesion was the result of pregnancy with visible villous tissue.

OUTCOMES

Her blood β-hCG gradually declined to a normal range in 28 days after the second operation. Menstruation occurred on day 20 after the second operation, and the duration and quantity were normal.

LESSONS

Although laparoscopy has many advantages, secondary pregnancy at the laparoscopic trocar port wound caused the patient enormous physical and mental pain and increased the medical costs. The etiology of secondary ectopic pregnancy at the laparoscopic puncture site was mainly an iatrogenic factor. Therefore, the procedure should be standardized to avoid its occurrence.
