Single-incision sleeve gastrectomy for successful treatment of a gastrointestinal stromal tumor

Laparoscopic RouxenY gastric bypass in Type 2 diabetes mellitus patient with low body mass index and gastric stromal tumor: A case report

Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been proved to be a safe and effective treatment for Type 2 diabetes mellitus (T2DM) patients with body mass index (BMI) >27.5 kg/m2 in China. The incidence of gastrointestinal stromal tumor (GIST) is very low, whereas the relevant studies on GIST and LRYGB are few. This is the first report of GIST associated with LRYGB in low BMI Chinese patient with T2DM.A male patient with GIST and T2DM, whose body weight and height were 67 kg and 175 cm, respectively,and the calculated BMI was 21.9 kg/m2. He was diagnosed by gastroscopy and enhanced CT scan. We used LRYGB to treat GIST and T2DM at the same time. After the operation, the GIST was removed successfully. Both the blood glucose levels and glycosylated hemoglobin were normal at 4 months and 1 year later. The patient received follow-up gastroscopy and abdominal CT scan and did not find out local recurrence and metastasis. LRYGB may be the best choice in treating GIST in T2DM with low BMI.

Transumbilical single-incision laparoscopic-assisted technique for removal of ileocecal foreign body

The aim of this paper is to present the case of a 40-year-old man who accidentally ingested a piece of metal. The patient complained of having intermittent right lower quadrant abdominal pain for 2 days. An abdominal X-ray was performed, and a piece of metal was found in the right lower quadrant of the abdomen. There was no gas in the abdominal cavity. Surgical treatment was therefore needed. Single-incision laparoscopic surgery (SILS) was attempted with conventional laparoscopic instruments. The foreign body was identified around the ileocecal region, an enterostomy was made and the foreign body was successfully removed. Subsequently, the incised ileocecal was wall sutured. The time for this surgery was 1 h with little bleeding. The patient made a quick recovery with a good cosmetic outcome. Based on this case, the use of SILS-assisted technique in the removal of an ileocecal foreign body proves to be safe and feasible.

Laparoscopic total gastrectomy for a giant gastrointestinal stromal tumor (GIST) with acute massive gastrointestinal bleeding: a case report

Gastrointestinal stromal tumors (GISTs) include 80% of gastrointestinal mesenchymal tumors that originate from interstitial Cajal cells and include 0.1–3% of GI malignancies, and the stomach is the most commonly involved organ. The only potentially curative treatment is surgical resection with clear margins. Although laparoscopic resection of small GISTs is a standard treatment, there is controversy about laparoscopic surgical resection for large and giant GISTs. A 52-year-old woman, a known case of large GIST of the stomach that was under neoadjuvant imatinib therapy, was admitted to the emergency department due to acute massive gastrointestinal bleeding (GIB). The patient underwent laparoscopic total gastrectomy and received adjuvant imatinib after surgery. Laparoscopic resection is a safe and feasible method in large and giant GISTs with oncologic and long-term outcomes comparable to open surgery, and with better short-term outcomes.

Endoscopically Assisted Transumbilical Single-Incision Laparoscopic Gastric Resection for GIST Treatment

PURPOSE

Complete surgical resection with negative margins without lymphadenectomy is the treatment of choice for nonmetastatic Gastrointestinal Stromal Tumors (GISTs). Laparoscopic resection of gastric GISTs <5 cm is an acceptable and oncologically feasible, safe, and effective treatment. We present our experience of an endoscopically assisted minimally invasive transumbilical single-incision laparoscopic (SILS) technique for gastric GISTs resection.

METHODS

Four patients with small gastric GISTs ≤5 cm located on the greater curvature or the anterior wall were resected with SILS by using a lesion-lifting technique under the guidance of flexible gastroscopy.

RESULTS

The technique was feasible and safe and offered significant advantages in locating the tumor and controlling the resection margins. There were no major intraoperative or postoperative complications, conversions, or tumor ruptures. Pathology showed low-risk GISTs resected with disease-free margins without tumor rupture. No recurrences have been observed.

CONCLUSION

The endoscopically assisted SILS wedge gastrectomy is a feasible, safe, and advantageous technique for the treatment of the greater curvature or anterior wall gastric GISTs.

Single port laparoscopy in gastroenterology and hepatology: A fine step forward

Single incision laparoscopy (SIL) has become an emerging technology aiming at a further reduction of abdominal wall trauma in minimally invasive surgery. Available data is encouraging for the safe application of standardized SIL in a wide range of procedures in gastroenterology and hepatology. Compared to technically simple SIL procedures, the merit of SIL in advanced surgeries, such as liver or colorectal interventions, compared to conventional laparsocopy is self-evident without any doubt. SIL has already passed the learning curve and is routinely utilized in expert centers. This minimized approach has allowed to enter a new era of surgical management that can not be acceded without a fruitful combination of prudent training, consistent day-to-day work and enthusiastic motivation for technical innovations. Both, basic and novel technical specifics as well as particular procedures are described herein. The focus is on the most important surgical interventions in gastroenterology and aims at reviewing the current literature and shares our experience in a high volume center.
