Study design 1-year prospective RCT. Objective Examine the effect of implantable pulse generator and low-frequency stimulation of the pelvic nerves using laparoscopic implantation of neuroprosthesis (LION) compared with neuromuscular electrical stimulation (NMES) in SCI. Methods Inclusion criteria: traumatic spinal cord injury (SCI), age 18–55 years, neurological level-of-injury Th4–L1, time-since-injury >1 year, and AIS-grades A–B. Participants were randomized to (A) LION procedure or (B) control group receiving NMES. Primary outcome measure: Walking Index for Spinal Cord Injury (WISCI-II), which is a SCI specific outcome measure assessing ability to ambulate. Secondary outcome measures: Spinal Cord Independence Measure III (SCIM III), Patient Global Impression of Change (PGIC), Penn Spasm Frequency Scale (PSFS), severity of spasticity measured by Numeric Rating Scale (NRS-11); International Spinal Cord Injury data sets-Quality of Life Basic Data Set (QoLBDS), and Brief Pain Inventory (BPI). Results Seventeen SCI individuals, AIS grade A, neurological level ranging from Th4–L1, were randomized to the study. One individual was excluded prior to intervention. Eight participants (7 males) with a mean age (SD) of 35.5 (12.4) years were allocated to the LION procedure, 8 participants (7 males) with age of 38.8 (15.1) years were allocated to NMES. Significantly, 5 LION group participants gained 1 point on the WISCI II scale, (p Conclusion The LION procedure is a promising new treatment for individuals with SCI with significant one-year improvement in walking ability.

Intragastric balloon (IGB) is a widely used, minimal invasive treatment for obesity. The IGB reduce gastric capacity and enhance feeling of fullness, thereby inducing weight loss. A rare, but severe complication to IGB treatment is gastric perforation. We present a rare case of gastric perforation, occurring shortly after a second IGB treatment. The patient was first treated with an Orbera® IGB for 12 months, exceeding the recommended treatment period of 6 months. Upon removal, esophagitis and gastritis was found. Therefore, insertion of the second IGB was postponed. After only 9 treatment-free days, a new endoscopy revealed a macroscopical normal gastric mucosa, and the second Orbera® IGB was inserted. The day after the insertion the patient was admitted to the hospital, due to extensive vomiting and mild epigastric pain. Three days after the insertion a gastric perforation was found. The patient underwent endoscopic removal of the IGB and laparoscopic suture of the perforation. The postoperative course was complicated due to recurrent multiple intra abdominal abscesses, treated with antibiotics, drainage and abscess puncture on several occasions. We suggest that patients should be carefully evaluated before IGB treatments are repeated, especially when gastritis is present. If the gastric mucosa is affected, sufficient time to let it heal is needed. The recommended treatment period should not be exceeded, and perforation should always be suspected as a differential diagnosis when patients present with abdominal symptoms after IGB insertion.

BACKGROUND: Anastomotic leakage is a serious complication following gastrointestinal surgery and is associated with increased morbidity and mortality. The incidence of anastomotic leakage is determined by anatomy and is reported to be between 4%-33% for colon anastomosis and 1%-3% for small intestine anastomosis. The etiology of anastomotic leakage of the intestine has been divided into three main factors: healing disturbances, communication between intra- and extra-luminal compartments, and infection. All three factors interact, and one factor will inevitably lead to the other two factors resulting in tissue ischemia, tissue necrosis, and anastomotic leakage.AIM: To evaluate ischemic metabolites and cefuroxime concentrations in both anastomosis and non-anastomosis ileum and colon in a porcine model.METHODS: Eight healthy female pigs (Danish Landrace breed, weight 58-62 kg) were included in this study. Microdialysis catheters were placed for sampling of ischemic metabolites (glucose, lactate, glycerol, and pyruvate) and cefuroxime concentrations in both anastomosis and non-anastomosis ileum and colon. Cefuroxime 1.5 g was administered as an intravenous infusion over 15 min. Subsequently, dialysates and blood samples were collected over 8 h and the ischemic metabolites and cefuroxime concentrations were quantified in all samples. The concentrations of glucose, lactate, glycerol and pyruvate were determined using the CMA 600 Microdialysis Analyzer with Reagent Set A (M Dialysis AB, Sweden), and the concentrations of cefuroxime and meropenem were quantified using a validated ultra-high-performance liquid chromatography assay.RESULTS: Only the colon anastomosis induced mean ischemic lactate/pyruvate ratios above 25 (ischemic cut-off) throughout the entire sampling interval, and simultaneously decreased glucose concentrations. The mean time for which cefuroxime concentrations were maintained above the clinical breakpoint minimal inhibitory concentration for Escherichia coli (8 µg/mL) ranged between 116-128 min across all the investigated compartments, and was similar between the anastomosis and non-anastomosis ileum and colon. For all pigs and in all the investigated compartments, a cefuroxime concentration of 8 µg/mL was reached within 10 min after administration. When comparing the pharmacokinetic parameters between the anastomosis and non-anastomosis sites for both ileum and colon, only colon Tmax and half-life differed between anastomosis and non-anastomosis (P < 0.03). Incomplete tissue penetrations were found in all tissues except for the non-anastomosis colon.CONCLUSION: Administering 1.5 g cefuroxime 10 min prior to intestine surgery seems sufficient, and effective concentrations are sustained for approximately 2 h. Only colon anastomosis was locally vulnerable to ischemia.

The use of a sentinel lymph node procedure (SN) in various cancer treatments including breast cancer is well examined. Little is known however, regarding the use of SN in colorectal cancer treatment. In this review, we explain the use of SN and its implications for future colorectal cancer treatment.
