RESUMO

BACKGROUND: Surgery for locally advanced rectal cancers beyond the plane of total mesorectal excision (TME) or extramesorectal nodal involvement should include complete resection. This study evaluated the oncologic feasibility and safety of robot-assisted surgery for rectal cancer beyond the TME plane. METHODS: The study analyzed the operative, perioperative, and oncologic outcomes for all patients who underwent robot-assisted extended rectal cancer surgery from April 2009 to February 2015. RESULTS: Of 36 patients, 22 underwent multivisceral en bloc resection, and 18 underwent extramesorectal lymph node (EMRLN) dissection. The median tumor location was 5 cm [interquartile range (IQR), 2.2-9.0 cm] from the anal verge. A total of 32 patients underwent neoadjuvant chemoradiation therapy. The median body mass index of the patients was 26.8 kg/m(2) (IQR, 24.0-31.9 kg/m(2)). Conversion was required for one patient because of inability to tolerate the Trendelenburg position. All the resections were R0, and there were no incomplete TMEs. The vagina and prostate or periprostatic structures were the most commonly resected (n = 13/22), and the lateral pelvic nodes were the most common EMRLNs (n = 16/18). The median numbers of examined mesorectal lymph nodes and EMRLNs were respectively 20 (IQR, 18.0-28.0) and 2.5 (IQR, 1.0-6.0). The median hospital stay was 4 days (IQR, 3.0-5.5 days). Six patients experienced Clavien-Dindo grade 3 complications, the most common of which was deep abscess (n = 5, 13.8 %). The 5-year actuarial local recurrence rate was 3.6 %. CONCLUSIONS: Minimally invasive resection for rectal cancer can be performed with extended lymph node dissection or en bloc multivisceral resection using the surgical robot in selected patients. This technique is feasible and has acceptable morbidity.

RESUMO

Interdigital neuromas are a common cause of forefoot pain, and approximately 80% of patients require surgical excision for symptom relief. Although 50% to 85% of patients obtain relief after primary excision, symptoms may recur because of an incorrect diagnosis, inadequate resection, or adherence of pressure on a nerve stump neuroma. The symptom relief rate after reoperation is similar to that after primary excision. A plantar longitudinal incision provides optimal exposure, and transposition of the nerve stump into bone or muscle and avoids traction or pressure on the nerve ending that can result in a painful stump neuroma. Preoperative counseling is essential to align patient expectations with potential outcomes.
