IntroductionHyperthermic intraperitoneal chemotherapy (HIPEC) is delivered after cytoreductive surgery (CRS) in selected patients with peritoneal carcinomatosis. The closed-abdomen technique, preferred by many centers, prevents heat loss and drug spillage, but does not warrant homogeneous distribution of the perfusion fluid (PF). The hypothesized formation of intra-abdominal adhesions during the closed-abdomen perfusion period has never been described.Materials And MethodsFrom March 2014 to April 2016, 10 consecutive patients with peritoneal carcinomatosis, selected for CRS, underwent the Laparoscopy-Enhanced HIPEC technique to explore the abdominal cavity during the perfusion. The aim of the study was to investigate the incidence and the extent of intra-abdominal adhesions that are formed after CRS during the perfusion period of closed-abdomen HIPEC.ResultsDuring the perfusion, adhesions developed in 70% of the patients. Adhesions developed mainly in the period between the closure of the abdomen and the subsequent filling of the abdomen with the PF. After their first division, during the following perfusion period, adhesions between the bowel and the abdominal wall reformed in 3 patients (30%).ConclusionsIntra-abdominal adhesions are frequently formed during closed-abdomen HIPEC and can hamper the adequate circulation of the PF. The Laparoscopy-Enhanced technique enables the early detection and the division of any intra-abdominal adhesions.
