Minimally Invasive Resection of Benign Gastric Tumors in Challenging Locations: Prepyloric Region or Gastroesophageal Junction

Benign gastric tumors in a prepyloric location or within 3 cm adjacent of the gastroesophageal junction (GEJ) are often challenging to resect using minimally invasive surgical techniques. The aim of this study was to examine the outcomes of patients who underwent minimally invasive enucleation or resection of benign gastric tumors at these difficult locations. The charts of patients undergoing minimally invasive resection of benign-appearing submucosal gastric tumors between June 2001 and December 2012 were reviewed. Data on tumor size and location, type of minimally invasive surgical resection, perioperative complications, 90-day mortality, pathology, and recurrence were collected. A total of 70 consecutive patients underwent laparoscopic resection of benign-appearing submucosal gastric tumors; there were 24 patients with lesions close to the GEJ and nine patients with lesions close to the prepyloric region. All lesions were successfully resected laparoscopically. For prepyloric tumors, surgical approaches included enucleation (n = 1), wedge resection (n = 2), and distal gastrectomy with reconstruction (n = 6). For tumors close to the GEJ, surgical approaches included enucleation (n = 16), wedge resection (n = 3), and esophagogastrectomy (n = 5). Complications in this series of 33 patients included late strictures requiring endoscopic dilation in three patients who underwent esophagogastrectomy. The 90-day mortality rate was zero. There were no recurrences over a mean follow-up of 15 months (range, 1 to 86 months). Minimally invasive enucleation or formal anatomic resection of submucosal tumors located adjacent to the GEJ or at the prepyloric region is safe and carries a low risk for tumor recurrence. Submucosal gastric lesions adjacent to the GEJ are amenable to laparoscopic enucleation or wedge resection unless they extend proximally into the esophagus. Prepyloric lesions often require formal anatomic resection with reconstruction.

Laparoscopic Enucleation

Laparoscopic resection of gastric submucosal tumors has been described, but the role of laparoscopy for tumors within the esophagus or near the gastroesophageal junction is not clearly defined. The aim of this study was to examine the outcomes of laparoscopic or thoracoscopic enucleation or wedge resection of benign gastric tumors. The charts of 44 patients who underwent minimally invasive resection of benign esophagogastric tumors were reviewed. Surgical approaches included thoracoscopic enucleation (n = 2), laparoscopic enucleation (n = 6), transgastric enucleation (n = 2), and laparoscopic gastric wedge resection (n = 34). There were 23 males with a mean age of 57 years. There was one conversion (2.5%) to laparotomy. Mean operative time was 97 ± 52 minutes. The mean length of hospital stay was 2.6 ± 2.0 days. One patient developed gastric outlet obstruction requiring Roux-en-Y reconstruction. There were no leaks and the 90-day mortality was zero. Pathology demonstrated gastrointestinal stromal tumor (n = 31), leiomyoma (n = 6), and other benign pathology (n = 7). There has been one tumor recurrence at a mean follow-up of 4.3 years. The laparoscopic approaches to local resection of gastric tumors are safe and feasible. The type of minimally invasive surgical approaches should be tailored based on the location and size of the lesion.

The Mean

Object Lumbar synovial cysts are a potential cause of radiculopathy and back pain, and the definitive treatment is the complete excision of the cyst. This report summarizes the authors' preliminary clinical experience with the minimally invasive resection of lumbar synovial cysts. Methods Nineteen patients (nine men and 10 women) with symptomatic synovial cysts underwent minimally invasive resection. The mean patient age was 64 years of age (range 43–80 years). The presenting symptom was radiculopathy in 16 patients, low-back pain in two, and lower-extremity weakness in one. There were 16 cases of a cyst located at the L4–5 level, two at L3–4, and one at L5–S1. The mean cyst diameter was 13.7 mm (range 3–30 mm). The mean follow-up time was 16 months (range 4–29 months). Clinical outcomes were graded, based on the Macnab modified criteria, as excellent, good, fair, or poor. Eighteen patients (95% of cases) reported either excellent (10 patients) or good (eight patients) results, and a fair result was reported by one patient (5% of cases). The mean operative time was 158 minutes (range 75–270 minutes), and the average intraoperative blood loss was 31 ml (range 10–100 ml). Two patients had intraoperative dural tears that resulted in cerebrospinal fluid leaks that resolved following primary closure. Conclusions Synovial cysts can be safely and effectively treated using minimally invasive surgical techniques. Long-term follow up is required to determine whether this approach results in less need for fusion than conventional surgical approaches.
