Single-incision laparoscopic-assisted surgery for colon cancer via a periumbilical approach using a surgical glove: Initial experience with 9 cases

AbstractOur initial experience of performing a single-incision laparoscopic-assisted (SILS) colectomy using a “home-made” multichannel port system is presented. Nine patients (5 women) with a median age of 67 years (range, 55–72 years) and a median body mass index of 21.2kg/m2 (range, 17.8–26.7kg/m2) underwent the SILS colectomy for colon cancer between September 2009 and March 2010. The sites of the primary tumor were the ascending colon (n=2), hepatic flexure (n=1), transverse colon (n=2), and sigmoid colon (n=4). Each trocar was introduced intraperitoneally through each finger of a surgical glove attached to the wound protector, which was applied to a midline fasciotomy made via a ¾-circular periumbilical incision. If necessary, one to three radial splits were added to the incision. The colon was mobilized intracorporeally, and the vessels were ligated intra- or extracorporeally. All the patients underwent a curative segmental colectomy without conversion to a standard multiport laparoscopy or open surgery. The median operative time and blood loss were 140min (range, 135–165min) and 50mL (range, 20–225mL), respectively. The median number of harvested lymph nodes was 18 (range, 6–31). The pathological stages included stage 0 (n=2), stage I (n=6), and stage III (n=1). The median number of postoperative analgesic use was one (range, 0–6). No intra- or postoperative complications occurred in this series. Our SILS colectomy procedure seems feasible and safe in selected patients with colon cancer

Distal gastrectomy via minilaparotomy for non-overweight patients with T1N0-1 gastric cancer: Initial experience of 30 cases

AbstractMinilaparotomy is considered to be a useful treatment alternative to laparoscopic-assisted surgery from the viewpoint of minimal invasiveness, although it has several limitations for the resection of malignant tumors. We evaluated the usefulness of distal gastrectomy via minilaparotomy for non-overweight patients with clinically diagnosed T1N0-1 gastric cancer. Clinicopathological and surgical data on 30 patients attempted to undergo distal gastrectomy via minilaparotomy (skin incision, ≤7cm) without laparoscopic assistance were analyzed. Inclusion criteria were clinically (preoperatively) diagnosed T1N0-1 gastric cancer that was not suitable for endoscopic mucosal resection located in the middle- or lower-third of the stomach and the patient body mass index ≤ 25.0 kg/m2. The minilaparotomy approach was successful in 27 patients (90%), while laparoscopic assistance was required to accomplish the procedures in three patients (10%). The type of lymph node dissection was D1 + α in 23 patients and D1 + β in 7 patients. The duration of surgery was 105–170 min (median, 143.5 min) and blood loss was 25–520 mL (median, 152.5 mL). Pathological stage was stage IA in 26 patients, IB in two patients, and stage II in two patients. Postoperative complications were wound infection in one patient, bleeding in one patient, and anastomotic ulcer in one patient. The length of postoperative stay was 7–41 (median, 11) days. With a median follow-up of 31 months, there was no recurrence. Distal gastrectomy via minilaparotomy seems feasible and safe in the majority of non-overweight patients with clinically diagnosed T1N0 gastric cancer

Metastatic Tumor of the Spermatic Cord in Adults: A Case Report and Review

Metastatic spermatic cord (SC) tumor is extremely rare. Recently, we experienced a case of late-onset metastatic SC tumor from cecal cancer. This case is a 68-year-old man presenting with a painless right SC mass. He had undergone a right hemicolectomy for cecal cancer 6 years ago. Radical orchiectomy and adjuvant chemotherapy with S-1 were performed. No recurrence was found after one year of follow-up. We identified a total of 25 cases, including our case, on a literature search via PubMed from January 2000 to April 2015. The most frequent primary sites of the tumors metastasizing to the SC were the stomach (8 cases, 32%) and the colon (8 cases, 32%), next the liver (2 cases, 8%), and kidney (2 cases, 8%). The majority of the cases underwent radical orchiectomy for the metastatic tumors of the SC. Over half of the cases received adjuvant interventions based on the regimens for the primary tumors. Prognosis in the patients with metastatic tumor of the SC was unfavorable except for late-onset metastasis. In patients with a mass in the SC and a history of neoplasm, especially in gastrointestinal tract, the possibility of metastasis from the primary cancer should be considered
