A Study on Rectum Cancer Surgery using Needlescopic instruments

Aims: We describe laparoscopic surgery for rectal cancer using needlescopic instruments performed at our department

Methods: From 2012 to 2016, 19 cases of rectal cancer underwent surgery using needlescopic instruments: 3 cases at rectosigmoid colon, 5 at upper rectum, and 11 at lower rectum. An umbilical camera port (12-mm) and two needlescopic instruments (EndoReliefTM) were directly punctured into the assistant surgical site. We started with 5 port sites. In low rectum cancer cases, we kept the good pelvic visualization to lifting the peritoneum of the bladder onto the ventral side using the Lone Star Retractor StaysTM.

Results: The median age was 70 years (56-91 years), with 9 males and 10 females, and body mass index was 21.1 kg/m2 (16-25 kg/m2). Anterior resection was performed in 2 cases, low anterior resection in 7 cases, intersphincteric resection in 4 cases, abdominoperineal resection in 4 cases, Hartmann’s procedure in 2 cases, and lateral lymph node dissection in 1 case. In addition, one case of T4b (bladder) was converted from laparoscopic to open surgery. However, there were no cases in which needlescopic instruments were replaced with conventional forceps. Moreover, intraoperative complications related to the forceps were not observed.

Conclusions: In rectum cancer surgery, needlescopic instruments leave a small postoperative wound; healing is rapid and the cosmetic result is excellent. Surgical safety is comparable to that using conventional forceps. There is no problem with the rigidity of needlescopic instruments. However, where the shaft is curved, operative control requires attention to mobility and directionality. In low rectum surgery, use of needlescopic instruments is limited due to the curvature of the shaft during the dissection of the anterior rectum wall, but it is possible to maintain a good field of view by using auxiliary equipment. Therefore, more cases could be considered for surgeries using needlescopic instruments with the help of auxiliary equipment.

Respuesta de SAGES al Estudio NordICC sobre el beneficio de las colonoscopias de detección

SAGES desea aclarar los resultados del estudio NordICC y colocarlos en contexto de los esfuerzos de varias agencias nacionales para reducir el riesgo de cáncer colorrectal – la segunda causa de muerte por cáncer más frecuente en los Estados Unidos-, mediante la promoción de la detección y tratamiento oportuno de las lesiones.

SAGES Response to NordICC Study Regarding Benefit of Screening Colonoscopies

The NordICC Study recently published in The New England Journal of Medicine and widely reported on by media outlets has raised questions regarding the benefit of screening colonoscopy in lowering the risk of colorectal cancer and cancer-related deaths among otherwise healthy and symptom-free men and women aged 55 to 64. Provocative headlines and commentaries have […]
