Background: The appendix is a vestigial organ which is infiltrated by faecal material, microbes and parasites. The most important aetio-pathology of appendicitis is obstruction of its lumen, by a faecolith. This results from accumulation and inspissation of faecal matter around vegetable fibres. The cause for appendicitis is numerous and one among them is parasitic infestation.
Aims: To analyze the faecolith present in the appendectomy specimen for parasites and to compare the results in fresh and preserved specimens.
Materials And Methods: Patients with acute/chronic appendicitis were subjected for surgery and the appendectomy specimens were collected in saline and formalin suspensions, for preservation purposes. The lumen was washed with normal saline and contents were collected and wet mount preparations were examined under low and high power microscopy.
Results: Among 100 specimens 48 faecolith analyses proved to be positive for parasitic association, giving 48% positivity, which is quite high. The commonest isolate was followed by mixed infection. In our study we observed that saline preparations were easy for handling and we were also able to demonstrate the undistorted morphology of parasite better than formalin preserved specimens.
Conclusion: This study reveals the importance of analyzing the appendectomy specimen for understanding the etiopathogenisis of appendicitis in spite of having a negative stool microscopy. A post surgical analysis of appendectomy specimen may surprise you with different etiological agents as confirmed by our study.

Safety and cost of selective histopathological analysis for detecting cancer in surgical specimens: a systematic review.
ANZ J Surg
January 2025
Department of Surgery, The Univeristy of Adelaide, The Queen Elizabeth Hospital, Adelaide, South Australia, Australia.
Article Synopsis
- The systematic review investigates the effectiveness and cost benefits of a selective histopathology approach for cancer detection, rather than the usual routine analysis of surgical specimens.
- It analyzed data from 11 studies involving over 26,000 patients who underwent various surgical procedures, identifying a low rate of cancer diagnoses but noting substantial cost savings.
- The conclusion emphasizes that while this selective method doesn’t significantly increase missed cancer diagnoses, there are concerns regarding legal protections for surgeons who opt out of routine histopathological analysis.
Should an Interval Appendicectomy Be Performed by a Minimally Invasive Gynaecologist?

Objective: We aimed to explore the abnormal pathology findings in appendix specimens removed based on intraoperative abnormal appearance during elective surgery for benign gynaecological conditions by a minimally invasive gynaecologist, as well as the associated complication rate.
Materials And Methods: This retrospective cohort study was conducted in a tertiary referral surgical centre for benign gynaecological conditions between the years 2004-2023. It included patients who underwent appendicectomy by a trained minimally invasive gynaecologist based on observations during surgery for benign gynaecological conditions.

Acute appendicitis is the most frequent abdominal surgical emergency worldwide. While luminal obstruction due to fecaliths and lymphoid hyperplasia is a common cause, parasitic infections are a rare but significant contributor. , the most common helminthic infection in developed countries, can trigger appendiceal inflammation through a mechanical obstruction or immune response.

Introduction: Mucinous appendiceal neoplasms are unique tumors in which >50 % of the tumor volume is composed of extracellular mucin. They may present as an unruptured mucin-filled appendix or, more commonly, with peritoneal metastases after rupture or transmural invasion of the primary tumor. This case report describes a case of presumed ovarian malignancy with final pathologic diagnosis of low grade appendiceal mucinous neoplasm.
