The Curious Incidence of Mucinous Adenocarcinoma Masquerading as Perianal Hidradenitis Suppurativa

Hidradenitis suppurativa (HS), also known as acne inversa, is a chronic inflammatory disorder affecting the terminal follicular epithelium within the apocrine skin glands. When these lesions develop in the genital and perianal regions, there is a potential risk of progression to squamous cell carcinoma or mucinous adenocarcinoma. The tumor may appear in the perianal area, perineum, or buttocks. Here, we present a rare case of long-standing perianal HS with associated fistula-related mucinous adenocarcinoma and the challenges we faced in managing this condition.

A Rare Incidence of Splenic Artery Aneurysm and Hypersplenism

A 31-year-old woman with Child's B liver cirrhosis with portal hypertension and splenomegaly presented with a one-month history of abdominal pain. A physical examination confirmed splenomegaly. A blood investigation revealed a low white blood cell (WBC) and platelet count. Computed tomography (CT) revealed a splenic artery aneurysm at the distal splenic artery measuring 3.4 x 3.4 x 4.3 cm (AP x W x CC) with thrombus and splenic infarction. A successful angiographic embolisation was performed without immediate complications. The abdominal pain symptoms resolved, leading to the patient's discharge from the ward on the third day post-embolisation. Follow-up at the surgical outpatient clinic indicated the patient remained asymptomatic, and repeated blood counts showed improvement in both WBC and platelet counts. Furthermore, follow-up CT scans demonstrated a reduction in spleen size, indicating positive outcomes and a favourable response to the intervention.

Ligation of the Intersphincteric Fistula Tract as an Emergency Treatment for Cryptoglandular Anal Fistula

Introduction

Ligation of the intersphincteric fistula tract (LIFT) is a sphincter-preserving procedure for treating anal fistula of cryptoglandular origin. Our prospective study aimed to determine the postoperative outcomes of patients undergoing LIFT in emergency and elective settings.

Methods

This was a single-centre prospective observational study of the LIFT procedure for the treatment of anal fistulas. The differences in the 6-month postoperative outcomes between the emergency and elective procedures were analysed, including the healing rate, healing time, recurrence rate, recurrence time, postoperative complications and length of hospital stay.

Results

Twenty-two patients were recruited for this study: 11 patients underwent LIFT as an emergency procedure (EM-LIFT), while the others underwent LIFT as an elective procedure (EL-LIFT). The healing rate for the EM-LIFT group was 90.9% (n = 10), with a median healing time of 2 months (range 0.5-4). For the EL-LIFT group, the healing rate was 100% (n = 11), with the same median healing time of 2 months (range 0.5-4). Two of the patients in the EM-LIFT group developed recurrence, with a median recurrence time of 5 months (range 4-6) and three developed recurrence in the EL-LIFT group, with the same median recurrence time of 5 months (range 4-6). There were minor postoperative complications of pain and subcutaneous infection, with no faecal incontinence. There was no statistically significant difference in postoperative outcomes between the groups.

Conclusion

EM-LIFT is a feasible and safe primary procedure for active cryptoglandular-type anal fistulas.

Sub-tenon Anaesthesia versus Intracameral Anaesthesia in Patients Undergoing Cataract Extraction: A Comparative Study of the Level of Pain, Visual Perception and Anxiety

Background: Phacoemulsification is a modern method of cataract extraction. Sub-tenon anaesthesia used to be the preferred anaesthetic technique for this procedure before intracameral anaesthesia gained its popularity in recent years. Nevertheless, many surgeons still believe that sub-tenon anaesthesia is better than topical anaesthesia. This study aimed to evaluate and compare the experiences of patients who were treated for cataract by phacoemulsification surgery using either sub-tenon or intracameral anaesthesia. Methods: Cross-sectional study conducted at Universiti Kebangsaan Malaysia Medical Centre, Kuala Lumpur, Malaysia. Participants were asked to complete a questionnaire within 1-2 hours following surgery. The questionnaires were designed to gather information on the patient’s level of anxiety, visual perception and amount of pain experienced during cataract surgery. Results: A total of 62 patients were included in the study. Thirty-one patients received anaesthesia by sub-tenon injection, whereas another 31 patients received anaesthesia by intracameral injection. There were no significant differences in the level of pain experienced by the two groups of patients during instillation of anaesthesia and during surgery (p=0.205 and p=0.592, respectively). There were also no significant differences in terms of visual perception and anxiety levels during surgery between the two groups (p=0.178 and p=0.731, respectively). Conclusion: Intracameral anaesthesia obviates the need for an injection during cataract surgery and is as comfortable for patients as sub-tenon anaesthesia in terms of visual perception, level of pain, and anxiety.
