Gastric neuroendocrine tumor (GNET) usually presents with nonspecific symptoms such as dyspepsia, nausea, and epigastric pain. They are usually diagnosed on histological evaluation of gastric polyps. Gastrointestinal bleed may be seen in large ulcerated polyps. However, massive gastrointestinal bleed leading to hematemesis is uncommon in GNETs. We describe a case of 55 years gentleman who was referred for massive hematemesis. On evaluation he was found to have a large ulcerated bleeding GNET. Laparoscopic resection of GNET was done.

  Introduction Top

Gastric neuroendocrine tumor (GNET) are rare lesions representing <10% of neuroendocrine tumors and <1% of all stomach neoplasms.[1] Majority of GNETs present with nonspecific symptoms and are mostly amenable to endoscopic resection. Gastrointestinal bleeding is an uncommon manifestation in GNETs and only few cases have been reported.[2],[3],[4],[5] Large GNET, GNET involving beyond submucosa, GNET with lymph node involvement and GNET associated with complications require surgical resection. Very little literature is available for laparoscopic management of GNET. Here, we report a 55-year-old male presenting with massive hematemesis who was diagnosed with large GNET and underwent laparoscopic resection.

  Case Report Top

A 55-year-old male patient presented with massive hematemesis for 1 day. At presentation, he had tachycardia (pulse rate – 118/min) and hypotension (blood pressure – 90/50 mmHg). The patient was pale and abdomen was soft and nontender. His hemoglobin was 7 g/dl. The patient was resuscitated and two units of blood were transfused. Rest of the investigations including liver function tests were within normal limits. Endoscopy showed a solitary submucosal tumor of size 2.5 cm × 2 cm with central ulceration at the posterior wall of proximal body of the stomach [Figure 1]. The tumor was already bleeding, so biopsy was not taken. Endoscopic ultrasound showed extension up to muscularis propria [Figure 2]. Contrast-enhanced computed tomography (CECT) scan of the abdomen was done which revealed arterial enhancing gastric tumor of size about 2.5 cm × 2 cm with no metastases [Figure 3]. After resuscitation, the patient was planned for surgery. After general anesthesia in supine position with split legs, pneumoperitoneum was established. A 10-mm supraumbilical port was introduced for the telescope. Liver was retracted with Nathanson retractor. Additional ports were placed, two in the left upper quadrant and one in the right upper quadrant. Intraoperative endoscopy was done to locate the tumor. Greater curvature at the level of tumor was mobilized and gastrotomy was made. Tumor was identified [Figure 4] and excised full thickness with Echelon ® 60 stapler taking 1 cm normal margin. Gastrotomy was closed with Echelon® 60 linear stapler. Specimen was delivered out using an Endobag. Postoperative period was uneventful. Liquid diet was started on postoperative day 1. The patient was discharged on the 2nd postoperative day. Histopathology showed neuroendocrine tumor and negative margins. The tumor stained positive for chromogranin A. Ki67 was <3%. Serum gastrin level was normal, and there was no evidence of multiple endocrine neoplasia (MEN) syndrome, and hence, he was diagnosed to have Type III GNET. On follow-up for 1 year, the patient had no evidence of any recurrences or metastasis.

  Discussion Top

GNETs are rare tumors. GNET arise from proliferating enterochromaffin-like cells.[1] There are three subtypes of GNET. Type 1 (70%–80%) is associated with autoimmune chronic atrophic gastritis. Type 2 (5%–8%) occurs with gastrinoma along with Zollinger-Ellison Syndrome (ZES) or associated with multiple endocrine Type I (MEN 1). Type 3 is sporadic associated with normal gastrin levels.[6] Type 1 and 2 are usually multiple whereas Type 3 was solitary. Interestingly, these lesions can acquire large sizes even without causing many symptoms as in the present case. Bleeding may be the presenting symptom but occurs only when the lesions become large and ulcerate. Large lesions occurring sporadically as in present case are a feature of Type 3 GNET. These lesions are uncommon and are extremely rare causes of gastrointestinal bleed.[2],[3],[4],[5] Type 3 tumors are usually large at presentation and have higher incidence for metastasis.

The optimal treatment of GNET is not well defined. Endoscopic polypectomy for Type 3 tumor implies a considerable risk of recurrence and progression of disease with as tumors behave significantly divergent with respect to higher incidence of metastasis.[7] Hence, surgery is recommended for Type 3 GNET for complete wide resection.

Laparoscopy is an emerging alternative approach with better patient compliance. Laparoscopic wedge resection for the diagnosis and treatment of gastric submucosal tumors has been previously employed and its efficacy has been established.[8],[9] However, little literature is available regarding role of laparoscopic wedge resection of GNET.[10] In lesions that are situated at difficult areas or lesions that are large for endoscopic resection, laparoscopic wedge resection appears to be safe and easy. Intraoperative endoscopy along with laparoscopy helps in deciding the exact site for gastrotomy and minimizes the percentage of the stomach to be resected.[11]

Laparoscopic resection for GNET is novel alternative to open and endoscopic surgery for large tumors and those failed or not suitable for endoscopic resection as it provides shorter hospital stay and better quality of life without compromising the oncological outcome.

  Conclusion Top

The GNET usually presents with nonspecific symptoms, but rarely, it can present with massive hematemesis and along with large a tumor. Laparoscopy is accepted as oncological safe for stomach tumors, and long-term outcomes are identical with that of open surgery. There is a lack of reports of laparoscopic surgery for GNET. These types of tumors can be managed by laparoscopic wedge resection. Laparoscopic surgery offers all the benefits of minimally invasive surgery without compromising the oncological outcome. Regular follow-up is necessary with medical and endoscopic surveillance to look for recurrences or distant metastasis.
