Single-incision assisted laparoscopic surgery (SILS) in the treatment of an intussusception induced by a solitary hamartomatous polyp: a case report and review of the literature

A Case Report and Literature Review of a Rare Jejunal Solitary Peutz-Jeghers-Type Polyp Resected Endoscopically in an Elderly Patient Presenting with Subacute Gastrointestinal Bleeding

Solitary Peutz-Jeghers-type polyp (SPJP) is a rare hamartomatous lesion. It is considered a different entity from Peutz-Jeghers syndrome despite similar histopathological findings. It can be found in the GI tract but rarely in the jejunum. Jejunal SPJP is susceptible to necrosis, ulceration, and intussusception, resulting in GI bleeding or small bowel obstruction. We describe a case of subacute gastrointestinal bleeding secondary to jejunal SPJP to share our approach to this challenging case using therapeutic endoscopy. An 81-year-old male patient with a history of atrial fibrillation on warfarin with stable therapeutic INR levels presented with a 1-week history of melena, generalized fatigue, and shortness of breath on exertion and was found to have profound iron deficiency anemia. Esophageal gastroduodenoscopy and colonoscopy failed to identify the source of bleeding; however, single-balloon enteroscopy detected a 4 cm polyp with a stalk in the proximal jejunum. Endoscopic polypectomy was performed, and the whole polyp was removed. Histopathological examination was consistent with Peutz-Jeghers polyp. The genetic analysis was negative for STK11 mutation. Follow-up magnetic resonance enterography and video capsule endoscopy did not reveal any other polypoid lesion in the GI tract. The patient's symptoms resolved gradually, and his hemoglobin level returned back to normal levels within 6 months. To our knowledge, this is the first case of endoscopic polypectomy during balloon-assisted enteroscopy for jejunal SPJP.

A rare cause of mechanical intestinal obstruction due to small bowel intussusception: 'A solitary Peutz-Jeghers type hamartomatous polyp'

Peutz-Jeghers Syndrome (PJS) is a rare autosomal dominant disorder which is characterized by hyperpigmentation in mucocutaneous membranes and hamartomatous polyps in the gastrointestinal tract (GIT). Common complications reported in patients with PSJ are bleeding and mechanical intestinal obstruction due to the hamartomatous polyps. There is also an increased risk of gastrointestinal and extra-intestinal malignancies in patients with PJS. A 28-year-old female patient was admitted to the emergency service with complaints of abdominal pain and vomiting. In addition to distention and tenderness on abdominal examination, revealed hyperpigmented lesions on her lips. An abdominal examination did not reveal any scar from the previous abdominal operation. The patient with suspected mechanical intestinal obstruction at pre-diagnosis demonstrated intussusception in the distal jejunal loops on abdominal tomography. In the diagnostic laparoscopy observed intussusception in jejunal loops. After a minimal suprapubic incision, small intestine loops were checked through alexis with bidigital palpation and no other intraluminal mass were detected. Laparoscopy-assisted jejunojejunal re-section and anastomosis was performed for the intussusception segment, where the polyb is located. It has been recommended that endoscopic polyps removal should be performed to avoid multiple surgical resections, which lead to short bowel syndrome. It has been recommended that endoscopic polyps removal should be performed to avoid multiple surgical resections, which lead to short bowel syndrome. By the nature of the disease, there may be multiple polyps simultaneously in the GIT and the associated risk of recurrent intussusception attacks in patients with PJS. To prevent short bowel syndrome and intra-abdominal adhesions due to repeated, laparo-tomies treatment with combined endoscopy and laparoscopic/laparoscopy-assisted surgery should be preferred in patients with PJS.

A case of jejunal solitary Peutz-Jeghers polyp with intussusception identified by double-balloon enteroscopy

Solitary Peutz-Jeghers polyp is a rare hamartomatous polyp that has similar histologic characteristics with those of polyps in Peutz-Jeghers syndrome, without associated mucocutaneous hyperpigmentation and a family history. Previous reports indicated that solitary Peutz-Jeghers polyp is rarely found in the small intestine. We experienced a rare case of jejunal solitary Peutz-Jeghers polyp. A 29-year-old man was admitted to our hospital with a 6-month history of upper abdominal pain. He had no hyperpigmentation or a family history of Peutz-Jeghers syndrome. Abdominal computed tomography showed a 3-cm tumor-like structure at the tip of a mildly intussuscepted jejunum. Per oral double-balloon enteroscopy revealed a 3-cm pedunculated polyp in the jejunum. The patient underwent partial jejunal resection under laparotomy. Macroscopically, the surgical specimen showed a pedunculated polyp, measuring 30 × 15 × 10 mm in size, with lobulated head. Histopathologic examination revealed irregular aggregation of hyperplastic crypts with branching muscular bundles originating from the muscularis mucosae. Based on these histologic findings, we finally diagnosed the patient as a solitary Peutz-Jeghers polyp in the jejunum. The present case indicated that solitary Peutz-Jeghers polyp should be considered in a patient with solitary hamartomatous polyp in the gastrointestinal tract.

Single-incision laparoscopic surgery for jejuno-jejunal intussusception caused by an angiolipomatous polyp in an adult: A case report

RATIONALE

Small bowel intussusception in adults is rare but is more likely to occur in the presence of a lead point. Surgical intervention is necessary in most cases, even if there is successful nonsurgical reduction of the intussusception.

PATIENT CONCERNS

A 54-year-old woman who was transferred to our emergency room with complaints of intermittent cramping pain of 4 days' duration.

DIAGNOSIS

Abdominal contrast-enhanced computed tomography revealed a jejuno-jejunal intussusception due to an angiolipomatous polyp.

INTERVENTION

A single-incision laparoscopic surgery (SILS) was performed without the need for any additional incisions.

OUTCOMES

She was uneventfully discharged on postoperative day 4.

LESSONS

The SILS procedure with adequate preoperative diagnosis by CT, with or without US, can offer good clinical outcomes for small bowel intussusception. Even surgeons who have little experience with laparoscopic intestinal anastomosis can consider SILS to treat small bowel intussusception in adults.

Gastrointestinal hemorrhage caused by adult intussusception secondary to small intestinal tumors: Two case reports

RATIONALE

Adult intussusception is rarely observed, and the clinical manifestations are very atypical. The most common symptom is abdominal pain, while the incidence of hematochezia is relatively low. We report two cases of adult intussusception secondary to small intestinal tumors with gastrointestinal hemorrhage as the main symptom.

PATIENT CONCERNS

Two men aged 19 and 54 years were successively referred to our department due to intermittent hematochezia. The hemoglobin levels of the two patients declined progressively, and conservative treatment was ineffective.

DIAGNOSES

The first patient underwent an abdominal computed tomography angiography examination, which showed that the intestine and its mesentery were tortuous, suggesting an intra-abdominal hernia or intussusception. The second patient underwent an abdominal computed tomography examination, which suggested a high possibility of an intussusception. The two patients were diagnosed as adult intussusception caused by small intestinal tumors.

INTERVENTIONS

Emergency laparoscopic explorations were performed. Enteroenteric intussusceptions caused by ileal tumors were found during surgery. Reduction of the intussusceptions and resection of the ileal tumors were performed.

OUTCOMES

The patients recovered well after surgery, and postoperative pathology showed that the tumors were a vascular hamartoma polyp and a lipoma.

LESSONS

Adult intussusception is very rare, particularly with gastrointestinal hemorrhage as the main symptom. Isolated hamartoma polyp is a rare cause of intussusception in adults. The clinical manifestations of adult intussusception are very atypical, and thus, making a preoperative diagnosis is difficult. Abdominal CT or CTA is an effective diagnostic method for adult intussusception. For adult patients with gastrointestinal hemorrhage caused by intussusceptions, active surgery should be performed when conservative treatment is not effective. Laparoscopic surgery is a safe and effective treatment for adult intussusceptions caused by benign diseases.

A case of single incision laparoscopic total colectomy for intestinal neuronal dysplasia type B

•

In patients with refractory constipation, it is necessary to care in mind that some patients require surgery.

•

Single incision laparoscopic surgery (SILS) is regarded as the major advance in minimally invasive surgery.

•

Total colectomy by SILS is very useful for the patients with intestinal neuronal dysplasia-type B.

Introduction

Intestinal neuronal dysplasia type B (IND-B) is an infrequent disease of the submucosal plexus of intestine manifesting chronic intestinal obstruction or severe chronic constipation. IND is rarely reported in adult patients.

Presentation of a case

The present study reports on the case of a 36 year-old woman suffering from longstanding chronic constipation and who was diagnosed with severe constipation in more than 20 years. Although she began to take a large amount of stimulant laxatives, such as “senna” and “bisacodyl”, constipation symptoms did not improve, she was admitted to our hospital. It was diagnosed with refractory constipation of the medication treatment-resistance, total colectomy with ileorectal anastomosis by single incision laparoscopic surgery (SILS) was performed. The final pathological diagnosis was IND-B.

Discussion

Refractory constipation after medical treatment is often seen in young generation. SILS has benefits of better cosmesis, reduced morbidity, reduced postoperative pain, and reduced length of hospital stay.

Conclusion

For the patients with refractory constipation associated with neuropathy such as IND, total colectomy by SILS was very effective.

Laparoscopic operation after pre-operative reduction of an intussusception-induced inflammatory fibroid polyp

Intussusception occurs mainly in children but rarely in adults. About 80–90% of adult cases of intussusception are due to benign or malignant neoplasms as a lead point. One of the causes is an inflammatory fibroid polyp (IFP), a rare, benign entity that occurs more frequently in the stomach than the ileum. We describe an uncommon case of a patient who presented with intussusception-induced IFP of the ileum. A 35-year-old woman presented with a 2-day history of abdominal pain. A computed tomography scan demonstrated ileocolic intussusception. During colonoscopy, reduction by pressured air easily released intussusception, and we suspected a submucosal tumour of the ileum. Successful pre-operative colonoscopic reduction was helpful for performing laparoscopic ileocecal resection 2 days later. Results of the histopathological examination confirmed a large IFP. The patient's post-operative course was uneventful. Pre-operative reduction by colonoscopy is effective for the diagnosis and treatment of intussusception-induced IFP.

Ileo-ileal intussusception caused by lymphangioma of the small bowel treated by single-incision laparoscopic-assisted ileal resection

Intraabdominal lymphangiomas are uncommon; additionally, those affecting the gastrointestinal tract are rare and account for less than 1% of cases. Intussusception caused by a cystic lymphangioma of the small bowel is extremely rare. The patient was a 20-year-old woman who visited our emergency room with a complaint of abdominal pain. A computed tomography image revealed ileo-ileal intussusception with a leading hypovascular mass measuring 1 cm in a diameter. Single-incision laparoscopic-assisted ileal resection was performed. The surgical specimen consisted of a soft polycystic mass. Macroscopically, a pedunculated polyp with a convolutional pattern was found. Microscopically, the inner surfaces of the cysts were covered with a single layer of endothelial cells. On immunohistochemical examination, the endothelial cells were partially positive for D2-40 and CD34. Smooth muscle cells were also found around the cysts. The lesion was diagnosed as a cystic lymphangioma. Dozens of cases of small bowel lymphangiomas have previously been reported. Of these, cases with intussusception were very rare. This is the first case of small bowel intussusception due to lymphangioma treated by single-incision laparoscopic-assisted surgery.
