Hemicolectomía derecha laparoscópica por incisión única por carcinoma de colon: técnica quirúrgica y resultados preliminares

Suprapubic single-incision laparoscopic right hemicolectomy with intracorporeal anastomosis

BACKGROUND

Single-incision laparoscopy (SIL) has gained significance recently. The umbilicus has been the preferred access site for SIL. Suprapubic access site (SAS) can be an alternative, especially for a right hemicolectomy (RH).

METHODS

Between November 2011 and July 2012, 7 consecutive patients underwent suprapubic SIL RH (SSILRH). The median age was 53 years, and the median body mass index was 23.9 kg/m2. Indications for surgery included appendicular tumor (1) and adenocarcinoma of the right colon (6). Three reusable trocars were used, and the resection was performed through the SAS. An intracorporeal linear stapled anastomosis was performed, the mesenteric defect was closed, and the access site was used for specimen extraction.

RESULTS

No patient required additional trocars or conversion to an open surgery. The median laparoscopic time was 222 minutes, and the median final incision length was 50 mm. The median Visual Analogue Scale score (0-10) at 6, 18, 30, 42, 54, 66, and 78 postoperative hours was 6, 6, 2, 2, 2, 2, and 2, respectively. The median hospital stay was 4 days.

CONCLUSIONS

SSILRH is useful because the SAS can be enlarged for extraction of the specimen without compromising the cosmetic outcome. The mesocolic and mesenteric dissections are on the same axis as the access site. The intracorporeal anastomosis can be performed without traction. Finally, positioning of the operative table improves exposure of the operative field and allows the surgeon to maneuver the colon and small bowel intracorporeally.

Single-incision right hemicolectomy for malignancy: a feasible technique with standard laparoscopic instrumentation

AIM

Single-incision laparoscopy is a rapidly evolving technique in the spectrum 'standard laparoscopy-natural orifice transluminal endoscopic surgery (NOTES)'. From a commercial perspective, purchase of articulating instruments is advised. However, here we present our early experience with single-incision laparoscopy for right hemicolectomy with standard laparoscopic instrumentation.

METHOD

Between June 2010 and December 2011, 25 patients presenting with malignant disease underwent single-incision laparoscopy for right hemicolectomy. Four different ports (SILS™ port, Covidien; SSL(®) Access system, Ethicon; X-Cone/S-Portal(®) , Storz; and OCTO™ port, AFS Medical) were used. Patients were recruited prospectively and all data were processed retrospectively.

RESULTS

Twenty-five patients were included in our study (and their characteristics, described later in this paragraph, are expressed as median (range)). Four conversions to standard laparoscopy were performed. The age of patients was 69 (36-89) years, and they had a body mass index (BMI) of 24.5 (19.1-34.2). The duration of surgery was 110 (70-148) min with a healed skin incision length of 35 (20-60) mm. Hospital stay was 5 (2-15) days. In four patients discharge was delayed because of comorbidity. One patient suffered an overwhelming pneumonia.

CONCLUSION

Single-incision laparoscopy using standard laparoscopic instruments appears to be a safe and feasible technique for malignant disease requiring right hemicolectomy. Randomized, prospective trials are ongoing to prove the benefits of this technique and to compare its oncological outcome measures with those of conventional laparoscopy. In our experience, a low-profile port with a wide intra-abdominal range of motion is most preferable.
