Experience with laparoscopic gastric resection: results and outcomes for 37 cases

Abstract

This study aimed to review the authors' technique, results, and outcomes for laparoscopic gastric wedge and segmental resections in patients with benign gastric diseases. A retrospective clinical chart review was performed for all the patients who underwent laparoscopic gastric resection at the Washington University Medical Center from 1997 through March 2004. The surgical approach, operative results, complications, and subsequent clinical course were analyzed. Data are expressed as mean +/- standard deviation. Laparoscopic gastric resection was attempted in 37 cases involving 21 women and 16 men with a mean age of 61 +/- 13 years. The indications for surgery included suspected gastric stromal tumor (GIST) or carcinoid (n = 22), other benign gastric lesions (n = 6), benign gastric outlet obstruction (n = 4), and nonhealing peptic ulcer (n = 5). Segmental resection using gastroenteric anastomosis, with or without vagotomy, was performed in 14 patients, wedge resection in 22 patients, and laparoscopic enucleation in 1 patient. Resection was totally laparoscopic in 25 cases and laparoscopically assisted (with an accessory incision) in 12 cases. The mean operative time was 165 +/- 58 min, and the blood loss was 84 +/- 77 ml. Two patients (5.4%) underwent conversion to open resection. Intraoperative gastroscopy was performed in 16 cases (44%) as an aid to the resection. Regular diet was resumed at a mean of 3.0 +/- 1.7 days, and the mean length of hospital stay was 3.9 +/- 2.1 days. Four patients (10.8%) experienced major complications including subphrenic abscess (n = 1), pneumonia with respiratory failure (n = 1), splenic vein injury requiring splenectomy (n = 1), and gastric outlet obstruction (n = 1) that required reoperation 1 year later. Minor complications included intraabdominal fluid collection (n = 1), postoperative gastroparesis (n = 1), urinary retention (n = 1), and incisional hernia (n = 1). Laparoscopic gastric resections can be performed safely in patients with a variety of benign gastric disorders. The use of an accessory incision for reanastomosis and specimen extraction facilitates the procedure in difficult cases.
