Laparoscopic parenchymal preserving hepatic resections in semiprone position for tumors located in the posterosuperior segments.

INTRODUCTION: All patients who underwent laparoscopic liver resections in the posterosuperior segments (LPSS) at our center were positioned in semiprone since August 2011. The aims of this study were to assess differences in perioperative outcomes between laparoscopic left lateral sectionectomies (LLLS) performed in supine position and LPSS in semiprone position. METHODS: We reviewed our prospectively collected database of all liver resections performed between January 2012 and January 2015. LLLS and LPSS were compared with respect to demographics and perioperative outcomes. RESULTS: Forty-five patients underwent LLLS (n = 20) or LPSS (n = 25). There were no differences in patient demographics or tumor diameter (p = 0.946). There were no conversions. Pringle maneuver was not used in both groups. There was no difference in peroperative central venous pressure (p = 0.511). The median operative time in the LLLS group was 100 min (60-260) and 160 min (95-270) in the LPSS group (p = 0.002) with median intraoperative blood loss in the LLLS group of 50 ml (0-550) versus a larger 150 ml (50-700) (p = 0.010) for patients receiving LPSS. No patients required transfusion. Intraoperative and postoperative complication rates were similar in both groups. Median hospital stay was 6 days in both groups (p = 0.554). CONCLUSION: LPSS in semiprone can be performed with similar clinical outcomes as a minor laparoscopic liver resection except for longer operative time and larger intraoperative blood loss without the need for transfusion.

SILS sigmoidectomy versus multiport laparoscopic sigmoidectomy for diverticulitis.

BACKGROUND AND OBJECTIVES: In this single-institution study, we aimed to compare the safety, feasibility, and outcomes of single-incision laparoscopic sigmoidectomy (SILSS) with multiport laparoscopic sigmoidectomy (MLS) for recurrent diverticulitis. METHODS: Between October 2011 and February 2013, 60 sigmoidectomies were performed by the same surgeon. Forty patients had a MLS and 20 patients had a SILSS. Outcomes were compared. RESULTS: Patient characteristics were similar. There was no difference in morbidity, mortality or readmission rates. The mean operative time was longer in the SILSS group (P=.0012). In a larger proportion of patients from the SILSS group, 2 linear staplers were needed for transection at the rectum (P=.006). The total cost of disposable items was higher in the SILSS group (P<.0001). No additional ports were placed in the SILSS group. Return to bowel function or return to oral intake was faster in the SILSS group (P=.0446 and P=.0137, respectively). Maximum pain scores on postoperative days 1 and 2 were significantly less for the SILSS group (P=.0014 and P=.047, respectively). Hospital stay was borderline statistically shorter in the SILSS group (P=.0053). SILSS was also associated with better cosmesis (P<.0011). CONCLUSION: SILSS is feasible and safe and is associated with earlier recovery of bowel function, a significant reduction in postoperative pain, and better cosmesis.
