A retrospective analysis and literature review of neoplastic appendiceal mucinous lesions

Abstract Background At present, the term mucocele is outdated, and mucinous appendiceal neoplasm is preferred. Mucinous appendiceal neoplasm is an uncommon pathology that occurs predominantly in middle-aged women. Its classification and management have been the subject of debate in recent decades. The aim of this study was to analyse the incidence, clinical management and survival of these tumours diagnosed in our centre in the last 10 years. Methods This was a retrospective observational study of patients with a diagnosis of appendiceal neoplasms between 2009 and 2018 in our centre. Variables such as sex, age, tumour type, clinical status, diagnosis, treatment and survival were collected. All data were analysed using the statistical program IBM SPSS Statistic® version 25. Results Twenty-nine patients with a diagnosis of appendiceal neoplasm were identified, and 24 corresponded to neoplastic appendiceal mucinous lesions (85.7%). The average age was 59.7 ± 17.6 years. Most patients were women (15 cases; 62.5%). Most of them presented with chronic abdominal pain (37.5%), and the diagnosis was performed by computed tomography (CT) (50%). The treatment was surgical in all cases. The surgical technique depended on the findings and histology of the tumour. Conclusion Mucinous appendiceal neoplasms are an uncommon entity, and their pathological classification and management have recently changed.

AbstractSmall bowel diverticulosis is a rare finding, with varied clinical presentations, which make the diagnosis difficult and delayed. Many cases are asymptomatic. However, it is an entity that can present with fatal complications. Here, we present a case of a 79-year-old male patient with diffuse small bowel diverticulosis, who presented with loose stools and acute exacerbation of chronic abdominal pain. Plain abdominal X-ray showed dilated bowel loops and pneumoperitoneum, which raised the possibility of bowel perforation. Computed tomography images revealed diffuse small bowel diverticulosis and pneumoperitoneum. Subsequent explorative laparotomy revealed no bowel perforation. Small bowel diverticulosis is a well-known cause of chronic/recurrent pneumoperitoneum without peritonitis or surgery.

The Right

The terminology of chronic abdominal pain, as well as further treatment tactics, are still the subject of debate. Conservative treatment in some patients with chronic abdominal pain is ineffective. Laparoscopic appendectomy is a scientifically based surgical intervention for patients with chronic abdominal syndrome with localization in the right iliac region in children who do not show peritoneal signs and changes in laboratory parameters, with the exception of intercurrent pathology by non-invasive methods.

Preoperative Ct

Symptomatic intestinal malrotation first presenting in the adults is rare. Midgut volvulus is the most common complication of malrotation in the adults. Because of more differential diagnosis, Computed Tomography (CT) scan can play an important role in the evaluation of patients with this abnormality. The whirl pattern around the superior mesenteric artery found on CT scan in patients with midgut volvulus is pathognomonic and diagnostic. We describe a case of intestinal malrotation complicated by midgut volvulus in an adult patient. The preoperative CT findings were pathognomonic.

Encapsulating Peritonitis

Sclerosing encapsulating peritonitis (SEP) is a disease that is rarely encountered clinically. Preoperative diagnosis of SEP can be difficult. However, with imaging technology, such as computed tomography (CT), this condition can be diagnosed without surgery and pathological analysis. SEP is characterized by small intestine being partially or completely encased by a layer of a thick grayish-white fibrocollagenous membrane similar to a cocoon. The most common symptoms of SEP are abdominal pain, nausea, and vomiting. SEP often leads to intestinal obstruction. Our hospital treated three emergency patients who complained of acute or chronic abdominal pain. CT showed “cauliflower sign” in two cases. The three patients were diagnosed with SEP intraoperatively. In a female patient with ascites, the situation was extremely serious, and this condition had not been reported in detail previously. Fortunately, all patients were discharged without complications. We should pay special attention to patients with SEP who have ascites, which indicates a serious situation.

Abdominal Symptoms

A middle-aged patient presented with intermittent chronic abdominal pain without any obvious cause. Computed tomography detected a hernia (presumed to be the cause of the patient’s symptoms) without any obvious lump on examination. A laparoscopy was performed to repair the hernia. This revealed a left-sided unilateral ‘peritoneal recess’ at the level of the arcuate line extending medial to the linea semilunaris. No extraperitoneal sac or defect was noted in the rectus sheath or in the muscle, nor were any contents present in the recess at the time of the laparoscopy. We believe the bowel was being trapped intermittently in this space, causing the abdominal symptoms.
