Case of idiopathic and complete appendiceal intussusception

Appendiceal intussusception is a rare disease in which the appendix invaginates into the cecum. It is often caused by organic diseases. The present case involved an appendiceal intussusception without an organic disease, and laparoscopic resection of part of the cecum was performed. Appendiceal intussusception has various causes, including malignant diseases. Therefore, diagnosis and selection of operative method are complex and could potentially lead to an excessively invasive option. By performing SILS with a multiuse single‐site port, we were able to provide an appropriate, non‐invasive treatment that had a good esthetic outcome.     

Preoperative sonographic diagnosis of appendiceal intussusception: A case report

Appendiceal intussusception is an uncommon form of intussusception. Most of the literature regarding appendiceal intussusception discusses the colonoscopic diagnosis or surgical treatment of the condition. Sonographic findings have rarely been described.

Intramucosal adenocarcinoma of the appendix: how to find and how to treat

A colonoscopic examination of a 58-year-old man revealed a small elevated lesion inside the orifice of the appendix. Using a polypectomy snare, a nodular polypoid lesion with a diameter of ca. 20 mm was removed from the lumen of the appendix. Histopathology showed that it was a well-differentiated adenocarcinoma. This is the first report of an intramucosal adenocarcinoma of the appendix diagnosed preoperatively; laparoscopy-assisted colectomy with a D2 lymph-node dissection was carried out. Endoscopists should consider an appendiceal tumor when an erosion, elevation, or deformity is seen in the head of the cecum.     

Cecorectal intussusception induced by a cecal hamartoma

Cecorectal intussusception, a variant form of intussusception, occurs when the cecum enters through the entire course of colon and reaches to the rectum. This condition is rare but often associated with a pathologic lead point. Here, we report a 13-year-old boy, featuring insidious abdominal discomfort and constipation for 1 month, who developed cecorectal intussusception. Before surgical intervention, multi-detector row computed tomography with reconstructed images demonstrated the route of cecorectal intussusception and identified a cecal fat-containing tumor as the lead point. The patient received surgical reduction with resection of the cecal tumor. Final pathological diagnosis was a hamartoma of the cecum. The relevant literature pertaining to this condition is reviewed, and the possible pathophysiology of the condition discussed.     

小儿阑尾套叠超声表现一例

1临床资料：阑尾套叠并不多见，发病率不到0.01%。报道阑尾套叠的文献少见，报道超声诊断阑尾套叠的文献罕见。阑尾套叠临床表现无特异性，诊断难度大。超声检查可以明确诊断。     

Sonography of appendiceal intussusception

A case in which appendiceal intussusception was diagnosed preoperatively by sonography is described. The sonographic finding of multiple concentric hypoechoic and hyperechoic rings was confirmed at laparotomy to be due to appendiceal intussusception. Demonstration of the sonographic coiled spring sign in the right lower quadrant should raise the possibility of appendiceal intussusception. The differential diagnosis is discussed.

Appendiceal submucosal mass as presentation of intestinal endometriosis

Submucosal lesions are mass‐like protuberances into the gastrointestinal lumen covered by normal mucosa. Making a definitive diagnosis is difficult because of the number of benign and malignant lesions and extrinsic compression. Here we report the case of a 42‐year‐old woman referred for colon polypectomy. Colonoscopy revealed a polypoid formation with externalization from the appendicular orifice covered by normal mucosa and another formation at the sigmoid colon. The histopathology of both lesions was normal. Endoscopic ultrasound showed a hypoechoic lesion that was slightly heterogeneous in the fourth layer, and CT colonography confirmed the findings. Surgical therapy with ileocolic resection and resection of the sigmoid lesion was performed. Surgical specimens revealed an appendicular intussusception by endometriosis and endometrial foci in the sigmoid. Intestinal endometriosis may have several presentations, but it should always be considered in the differential diagnosis of a submucosal lesion in the colon.     

Endoscopic diagnosis and treatment of an appendiceal mucocele: A case report

BACKGROUNDAppendiceal mucocele is a rare disease that causes obstructive dilatation of the appendix due to the intraluminal accumulation of mucin. We report a case of endoscopic diagnosis and treatment of an appendiceal mucocele.CASE SUMMARYA 47-year-old man presented with a protrusion around the orifice of the appendix discovered by colonoscopy incidentally. He was admitted to our hospital for a routine checkup without any symptoms. Abdominal computed tomography showed a cystic mass approximately 3 cm in diameter with fat stranding. The preoperative diagnosis was non-neoplastic appendiceal mucocele, and endoscopic treatment was performed. The endoscopic findings and pathological results supported our preoperative diagnosis. The endoscopic treatment of appendiceal mucocele was feasible and effective, which was confirmed by repeated endoscopy and post-operative computed tomography after 7 mo. CONCLUSIONEndoscopic therapy provides a new method for the treatment of appendiceal mucocele.     

Adult intussusception caused by an appendiceal mucocele and reduced by colonoscopy

Appendiceal intussusception is a very rare disease that is found in only 0.01% of patients who have undergone an appendectomy. Clinical symptoms vary but include acute appendicitis symptoms such as right lower quadrant abdominal pain or repetitive right lower quadrant crampy pain. Some patients are asymptomatic. Operative treatment is necessary to reduce an appendiceal intussusception in adults, but there is a debate about how to perform the reduction. Successful colonoscopic reductions have been recently reported for some cases. We report a case of appendiceal intussusception that was diagnosed, reduced by colonoscopy, and histologically confirmed as a mucinous cystadenoma after the operation.     

Ileocolocolic intussusception secondary to a submucosal lipoma: An unusual cause of intermittent abdominal pain in a 62‐year‐old woman

We present a case of subacute nonobstructing ileocolocolic intussusception secondary to a submucosal lipoma and a mobile cecum diagnosed sonographically in a 62‐year‐old woman. The patient was seen following a 2‐month history of nonspecific intermittent pain in the right and middle abdomen and weight loss. Sonography revealed ongoing intussusception involving distal ascending and transverse colon. Analysis of the distal intussusception end demonstrated a 3.0 × 2.5 cm echogenic polypoid lesion consistent with a lipoma serving as a lead point. The sonographic diagnosis was confirmed at surgery. © 2009 Wiley Periodicals, Inc. J Clin Ultrasound, 2010.

Laparoscopic repair of secondary perineal hernia with coverage by the mobilized cecum

The incidence of secondary perineal hernia (SPH) has increased since the introduction of extralevator abdominoperineal resection and laparoscopic abdominoperineal resection. Currently, laparoscopic mesh repair is the usual procedure. Here, we demonstrate a repair of SPH without mesh that uses the mobilized cecum to cover the pelvic hernial orifice. An 83‐year‐old man complained of discomfort when sitting for long periods. He was status post laparoscopic abdominoperineal resection and was diagnosed with SPH. Hernia repair was performed. After transperitoneal adhesiolysis in the inferior pelvis, the right colon was laparoscopically mobilized, and the pelvic orifice was covered by suturing the cecum to the pelvic brim. The perineal skin was managed with negative pressure wound therapy. The postoperative course was uneventful. There has been no sign of recurrent herniation for 12 months. This method of SPH repair is simple to perform and avoids mesh‐related complications.     

Retrograde colon intussusception in an adult due to adenoma: Treatment by combined laparoscopic and endoscopic approach

This report describes the case of a young patient who underwent laparoscopic surgery to reduce for a retrograde intussusception of the sigmoid‐descending colon caused by adenoma of the sigmoid colon. A 36‐year‐old woman visited our hospital, complaining primarily of vomiting and abdominal pain. Abdominal CT scan showed the typical finding of intussusception. An emergency colonoscopy revealed that the invaginated colon with a polypoid mass was protruding into the descending colon. A gastrografin enema showed the invaginated bowel segment at the descending colon. We performed endoscopic polypectomy and then hand‐assisted laparoscopic reduction. The pathological finding showed tubular adenoma. Laparoscopy is a diagnostic or therapeutic tool for selected cases of adult intussusception. Benign tumor is one of the causes of intussusception in adults and a good indication for laparoscopic surgery.     

A case of giant lipoma causing chronic recurrent intussusception of the colon

Colonic lipomas, which often occur in elderly women, usually have small size and occur mainly in the cecum and ascending colon. Most colonic lipomas are asymptomatic and identified incidentally at the time of endoscopy or surgery. However, they may cause symptoms such as bleeding, obstruction or intussusception as their size increases. Intermittent episodes of intussusception are uncommon but may be caused by large pedunculated lipoma. In a 68-year-old woman suffering intermittent abdominal pain, 5.5×4.5×3.8-cm huge mass was found by colonoscopy at proximal ascending colon, which was intussuscepted to proximal transverse colon on abdominal computed tomography. Segmental right colonic resection was conducted. We report a case of symptomatic giant pedunculated colonic lipoma causing intussusception requiring surgical intervention, with a successful recovery after surgery.

Double intussusception in a teenage child with Peutz-Jeghers syndrome: A case report

BACKGROUNDPeutz-Jeghers syndrome (PJS) is a genetic disorder characterized by the development of gastrointestinal hamartomatous polyps and mucocutaneous melanin pigmentation. Patients with PJS are at risk of complications such as intussusception. Intussusception is a condition where one segment of the intestine invaginates into another, causing intestinal obstruction. We report a PJS patient who was diagnosed with double intussusception in a single setting. CASE SUMMARYA 16-year-old teenage male PJS patient presented with a history of colicky abdominal pain, vomiting, blood in stools, loss of appetite, and weight loss. On abdominal examination, a vague mass was palpable over the right upper quadrant. Contrast-enhanced computed tomography (CT) of the abdomen was performed and an intussusception involving the jejunum and rectosigmoid junction was observed. The patient subsequently underwent a laparotomy and intussusception involving the jejunum and another over the ileum was noted intra-operatively. Bowel resection and an endoscopic polypectomy were performed, followed by a primary anastomosis. The patient was discharged well and reviewed again one month later, and was noted to be well.CONCLUSIONPJS patients have a high risk of intussusception and can be diagnosed accurately by endoscopic surveillance or radiologically with abdominal CT or magnetic resonance imaging. The mainstay of treatment is surgical intervention followed by endoscopic surveillance with periodic polypectomy.
