Single-incision laparoscopic surgery for small bowel resection with an intraumbilical arcuate incision in children

A case of single-incision laparoscopic surgery for a bleeding Meckel's diverticulum diagnosed pre-operatively by double-balloon endoscopy

INTRODUCTION

　Meckel's diverticulum (MD) is a congenital true diverticulum that is residual yolk duct tissue, and some cases with complications require surgery. It has been reported that laparoscopic surgery is effective for patients with an MD.

PRESENTATION OF CASE

A 79-year-old man with melena visited our hospital. Upper gastrointestinal series and colonoscopy showed no bleeding lesion. Double-balloon endoscopy was then performed to examine the small intestine. The examination showed a large diverticulum 80cm proximal to the ileocecal valve and a circular ulcer. MD resection was performed using single-incision laparoscopic surgery (SILS) technique through a 3-cm zig-zag incision in the umbilicus. Three ports were inserted for the scope and forceps devices. The MD was located 80cm proximal to the ileocecal valve. There were no other intestinal lesions. From the wound, the lesion could be easily moved outside the body. The MD including the ulcer lesion was then resected. The patient's postoperative course was good, and he rarely felt wound pain. He started dietary intake three days after surgery and was discharged from hospital eight days after surgery.

DISCUSSION

SILS technique has attracted attention in the field of laparoscopic surgery. Using a single port with multiple working channels, SILS can reduce the number of incisions and the rates of incisional hernia port site-related complications, as well as improve cosmesis.

CONCLUSION

A definite diagnosis of an MD was made by double-balloon endoscopy preoperatively. The SILS approach was effective for cosmesis, postoperative pain, and a shortened hospital stay.

Success of Minimally Invasive Transumbilical Single-Incision Laparoscopic Surgery (T-SILS) Plus Double-Balloon Endoscopy (DBE) for Pediatric Intestinal Angiodysplasia: A Case Report

We describe here a child with angiodysplasia of the small intestine, diagnosed by double-balloon endoscopy (DBE), who was treated with transumbilical single-incision laparoscopic surgery (T-SILS). A 9-year-old boy presented to another hospital with intermittent fresh melena of a duration of 5 months and 4 days. Anoscopy and gastric mucosal membrane scintigraphy were unsuccessful diagnostically, and he was referred to our hospital for further examination and treatment. Under general anesthesia, we performed DBE by an anal route, with the ileum assessed for a distance of about 150 cm from the ileocecal valve. Although no bleeding lesion was found in the colon, a flat elevated venous lake approximately 20 mm in size was observed 20 cm from the ileocecal valve, suggesting angiodysplasia of the small intestine. A tattoo was made under DBE, and wedge resection by T-SILS was performed 1 month later under general anesthesia. The excised specimen appeared as a flat, elevated venous lake approximately 20 mm in size. Histopathologic analysis revealed several dilated and distorted veins within the submucosa of the small intestine. The patient was diagnosed with angiodysplasia of the small intestine. His postoperative course was uneventful, and he remained free of recurrent gastrointestinal bleeding 18 months after the operation. This is the first case report showing the diagnosis, localization, and tattooing of an obscure gastrointestinal bleeding lesion of the small intestine by preoperative DBE and removal of the lesion by subsequent T-SILS in children.

Laparoscopic excision of Meckel's diverticulum in children: What is the current evidence?

Complications aroused from Meckel’s diverticulum tend to developed in children. Children presented with abdominal pain, intestinal obstruction, intussusception or gastrointestinal bleeding may actually suffered from complicated Meckel’s diverticulum. With the advancement of minimally invasive surgery (MIS) in children, the use of laparoscopy in the diagnosis and subsequent laparoscopic excision of Meckel’s diverticulum has gained popularity. Recently, single incision laparoscopic surgery (SILS) has emerged as a new technique in minimally invasive surgery. This review offers the overview in the development of MIS in the management of children suffered from Meckel’s diverticulum. The current evidence in different laparoscopic techniques, including conventional laparoscopy, SILS, the use of special laparoscopic instruments, intracorporeal diverticulectomy and extracorporeal diverticulectomy in the management of Meckel’s diverticulum in children were revealed.
