Staged restorative proctocolectomy: laparoscopic or open completion proctectomy after laparoscopic subtotal colectomy?

Background The aim of this study was to compare outcomes of laparoscopic and open completion proctectomy (CP) and ileal-pouch anal anastomosis (IPAA) after a previous laparoscopic subtotal colectomy (STC). Methods From a prospectively maintained ileal pouch database, outcomes for patients who underwent laparoscopic CP after laparoscopic STC (LSTC-LCP group) for ulcerative or indeterminate colitis were compared to those for patients who underwent open CP (LSTC-OCP group). A control group of open CP after open STC (OSTC-OCP group) was case-matched to LSTC-OCP at a ratio of 1:2 for age at surgery, gender, body mass index (BMI), year of operation, and American Society of Anesthesiologists (ASA) classification. Demographics, perioperative data, and pouch function were compared. Quality of life was evaluated using the Cleveland Global Quality of Life Scale (CGQL). Results Between 1997 and 2009, 47 patients underwent LSTC followed by LCP (LSTC-LCP), and 48 patients underwent OCP after LSTC (LSTC-OCP); the latter group was matched to 96 open-open patients (OSTC-OCP). There were no significant differences in demographic and preoperative data among the three groups, except that the OSTC-OCP group patients were younger. Postoperative morbidity, pouch function, and CGQL were similar. LSTC-LCP patients had lower estimated blood loss (EBL) (p < 0.001), less commonly described intraoperative adhesiolysis (p < 0.001), reduced length of hospital stay (LOS) (p = 0.002) but longer operating time (p = 0.001) at CP/IPAA when compared with open-open patients. For patients with previous LSTC, LCP was associated with less commonly described intraoperative adhesiolysis (p = 0.003) and shorter LOS (p = 0.003) than OCP but a longer operating time (p = 0.036). Conclusions Laparoscopic CP and IPAA can be performed with safety comparable to that of open surgery after previous laparoscopic STC. The laparoscopic approach is associated with advantages including reduced intraoperative blood loss and earlier recovery as demonstrated by shorter length of hospital stay.
