Cytoreductive surgery (CRS) including gastric resection combined with hyperthermic intraperitoneal chemotherapy (HIPEC) can improve the prognosis of selected patients with peritoneal surface malignancies. Perioperative morbidity of this aggressive treatment strategy is high; however, overall mortality can be low in specialized centers. The aim of this study was to assess the safety of gastric resections with anastomosis during CRS and HIPEC.
Between 2005 and 2008, 204 patients underwent CRS and HIPEC at our tertiary referral centre. Of these, 37 procedures (male/female 24/13, median age 55 years) included gastric resections. The clinical data of all patients were introduced into a database and analyzed with respect to the morbidity associated with the gastric resections.
Of all patients included, 16 had pseudomyxoma peritonei, 11 gastric carcinoma, 4 ovarian carcinoma, 3 malignant peritoneal mesothelioma, and 3 colon carcinoma. Twenty-seven patients had previous surgery (n = 22) and/or systemic chemotherapy (n = 18). Fifteen total gastrectomies, 3 subtotal gastrectomies, 12 distal gastrectomies, and 7 gastric wedge resections were performed during CRS. The overall postoperative morbidity was 45%; main surgical complications were pancreatitis (n = 6), abdominal abscess (n = 4), bile leakage (n = 2), and digestive fistula (leakage of ileorectostomy and small bowel perforation) (n = 2). However, no complications occurred at the site of the esophageal anastomosis (n = 15), gastric anastomosis (n = 15) or gastric suture (n = 7). No patient died postoperatively during the hospitalization period.
CRS in combination with HIPEC is associated with high postoperative morbidity; however, anastomosis following total or subtotal gastrectomy is safe in experienced centers. No leakages related to gastric resections occurred in this high-risk patient group.
