In the surgical treatment of pancreatic cancer, margin-negative status is one of the most important determinants of survival. We conducted this study to explore surgical margin status as well as other factors affecting the survival of borderline-resectable pancreatic cancer (BRPC) patients who received neoadjuvant chemotherapy with gemcitabine and S-1. ⋯ In the neoadjuvant setting, gemcitabine and S-1 improved the negative surgical margin rate in BRPC patients, but it did not improve survival. Thus, neoadjuvant chemotherapy should be given to BRPC patients at an earlier stage.

To evaluate the safety and efficacy of induction SOX (S-1 + oxaliplatin) ± cetuximab chemotherapy followed by short-course chemoradiotherapy and surgery in patients with poor-risk locally advanced rectal cancer. ⋯ The regimen of induction SOX (S-1 + oxaliplatin) ± cetuximab chemotherapy followed by short-course chemoradiotherapy is safe and is associated with good tumor regression in patients with poor-risk locally advanced rectal cancer.

The long-term survival of patients with peritoneal carcinomatosis of colorectal origin has been achieved with cytoreductive surgery, which removes all macroscopic implants, combined with hyperthermic intraperitoneal chemotherapy (HIPEC). The current technology for administering intraperitoneal heated chemotherapy is expensive and, for some institutions, unaffordable. We conducted this study to assess the temperature stability provided by a modified, inexpensive system, to offer a simple and low cost alternative to the standard HIPEC delivery equipment. ⋯ Analysis of this data demonstrates that the uniform delivery of HIPEC at 41° with this modified system is feasible and safe. The outcome of the patients treated with cytoreductive surgery and HIPEC with this modified system compares favorably to other published series. Its low cost and simple design will give more patients with peritoneal carcinomatosis access to this treatment.

Randomized Controlled Trial
Ultrasound-guided ilioinguinal/iliohypogastric block did not reduce emergence delirium after ambulatory pediatric inguinal hernia repair: a prospective randomized double-blind study.
Emergence delirium (ED) is a common postoperative complication of ambulatory pediatric surgery done under general anesthesia with sevoflurane. However, perioperative analgesic techniques have been shown to reduce sevoflurane-induced ED. The primary objective of this investigation was to examine whether an ultrasound-guided ilioinguinal/iliohypogastric (II/IH) nerve block for ambulatory pediatric inguinal hernia repair could reduce the incidence of sevoflurane-induced ED. ⋯ UMIN000008586.

The laparoscopic technique for repairing ventral and incisional hernias (VIH) is now well established. However, several issues related to laparoscopic VIH repair, such as the high recurrence rate for hernias with large fascial defects and in extremely obese patients, are yet to be resolved. Additional problems include seroma formation, mesh bulging/eventration, and non-restoration of the abdominal wall rigidity/function with only bridging of the hernial orifice using standard laparoscopic intraperitoneal onlay mesh repair (sIPOM). ⋯ Although detailed techniques for fascial defect closure and handling of the mesh have been published, standardized techniques are yet to be established. We reviewed the literature on IPOM-Plus in the PubMed database and identified 16 reports in which the recurrence rate, incidence of seroma formation, and incidence of mesh bulging were 0-7.7, 0-11.4, and 0 %, respectively. Several comparison studies between sIPOM and IPOM-Plus seem to suggest that IPOM-Plus is associated with more favorable surgical outcomes; however, larger-scale studies are essential.
