A Clinical-Anatomical-Radiological Study of Extraperitoneal Spaces: A Case Series.

Complications can arise secondary to anorectal suppurative diseases, with infections spreading along the extraperitoneal space, such as the peri-vesical, prevesical, pre-sacral, and pararectal spaces, resulting in abscesses at remote sites, which can make diagnosis more challenging. Due to the absence of peritonitis symptoms, there is a delay in presentation among such patients. Comprehending the intricacies of these areas and the way infection can spread within them is crucial for promptly identifying and effectively draining the extraperitoneal abscess. We present a case series of six patients with a mean age of 45, all males. A total of three patients had undergone incision and drainage after being diagnosed with anorectal suppurative disease and remained symptomatic after the initial surgical intervention of incision and drainage. Two patients initially diagnosed with anterior abdominal abscesses patients, after being treated with incision and drainage, continued to have purulent discharge from the drainage site. Finally, the last patient continued to present with perianal pain after an open hemorrhoidectomy. CT scans of all six patients showed collections in the extraperitoneal spaces correlated with the observed complications. To deepen our understanding of pelvic extraperitoneal spaces, cadaver dissections were conducted and compared with CT images. Through cadaver dissections and CT imaging, the study provides insights into the anatomy and interconnections of pelvic extraperitoneal spaces, emphasizing the importance of early CT scans for diagnosis. Understanding these intricate anatomical structures is essential for accurate diagnosis and efficient and effective treatment. Timely diagnosis is vital to prevent prolonged illness and reduce the risk of complications and mortality. The importance of early CT scans in suspected patients is underscored, which is highly important to expedite appropriate actions.

Preservation of parathyroid glands during thyroid and neck surgery.

The parathyroid glands are situated in close proximity to the thyroid gland. They have an important endocrine function maintaining calcium and phosphate homeostasis in the body by the secretion of parathormone (PTH), which is responsible for this function. The parathyroid glands are commonly damaged during thyroid surgeries. This could lead to transient or permanent hypoparathyroidism in 30% of cases. Preservation of the parathyroid glands, is an important and integral part of thyroidectomy and other surgical interventions in the neck. The main principle underlying this is a thorough understanding of parathyroid anatomy in relation to the thyroid gland and other important structures in the area. There can also be significant variation in the anatomical location of the glands. Various techniques and methods have been described for parathyroid preservation. They include intraoperative identification utilizing indocyanine green (ICG) fluorescence, carbon nanoparticles, loupes, and microscopes. The techniques of surgery (meticulous capsular dissection), expertise, central compartment neck dissection, preoperative vitamin D deficiency, extent and type of thyroidectomy are the risk factors associated with damaged thyroids, inadvertent parathyroidectomy and subsequent hypoparathyroidism. Parathyroid Autotransplantation is a treatment option for inadvertent parathyroidectomy. Ultimately, the best way to assure normal parathyroid function is to preserve them in situ intraoperatively undamaged.

Role of inflammatory markers as predictors of laparotomy in patients presenting with acute abdomen.

BACKGROUND: There is a need for an ideal indicator of surgery in patients presenting with acute abdomen. Several markers have been analysed, but the search still continues as none have proven effective. This study aimed to analyse and compare the predictive value of plasma procalcitonin (PCT) strip test in patients presenting with acute abdomen and identify a useful cut-off value to differentiate patients that would benefit with surgery from those that require conservative management. METHODS: A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma PCT was estimated by the semi-quantitative strip test. The levels of plasma PCT and other routinely used markers of inflammation were analysed and compared. RESULTS: Of the total of 58 patients, 44 patients (76%) were men with a mean age of 45 years. Forty patients required emergency surgical intervention. A plasma PCT value of >0.5 ng/mL at admission was 80% sensitive and 100% specific for predicting need for antibiotics in patients with acute abdomen that were managed conservatively. The mean plasma PCT value in the patients undergoing surgery (5.0-10.0 ng/mL) was significantly more than in those managed conservatively (0.5-2.0 ng/mL). Using receiver operating characteristic (ROC) curves a cut-off for plasma PCT of >5.0 ng/mL was 75% sensitive and 100% specific for considering surgical intervention in patients presenting with acute abdomen. CONCLUSIONS: Plasma PCT (value >5 ng/mL) could be used as an adjunct to clinical examination to predict requirement of surgery in patients presenting with acute abdomen.
