Purpose: We constructed a reliable continent tube that is surgically simple.
Materials And Methods: In 12 patients with malignant bladder tumor we performed radical cystectomy with isolation of a 50 cm. ileal loop with pedicle. The proximal segment (8 to 10 cm.) was tapered over a 16Fr catheter as an efferent tube, the remaining segment was detubularized to create a W-shape pouch and the tapered ileum was fixed to the back surface of the rectus muscle with 2 polyester tapers 1 cm. wide with a suspension tension of 500 g. The external orifice of the tapered ileum was anastomosed to the umbilicus. In 2 patients with neuropathic bladder a 15 cm. ileal loop with pedicle was isolated, the proximal segment (8 cm.) was tapered as an efferent tube with 500 g. suspension tension, and the remaining segment was detubularized and anastomosed to the bladder.
Results: The patients were followed for 6 to 17 months (mean 11.4) and were completely continent day and night. The stoma was easily catheterized with a 16Fr catheter in all cases. Urodynamic study of the efferent tubes revealed maximum pressure of 84 to 159 cm. water (mean 114). Retrograde radiography of the efferent tubes demonstrated perfect canalization without stenosis.
Conclusions: This study suggests that the continent mechanism of the tapered ileum can be greatly enhanced by a suspension technique. This maneuver also provides easy catheterization and surgical simplicity.

Motile cilia are evolutionarily conserved organelles. In humans, multiciliated cells (MCCs), assembling several hundred motile cilia on their apical surface, are components of the monolayer epithelia lining lower and upper airways, brain ventricles, and parts of the reproductive tracts, the fallopian tube and uterus in females, and efferent ductules in males. The coordinated beating of cilia generates a force that enables a shift of the tubular fluid, particles, or cells along the surface of the ciliated epithelia.

Endoscopic or fluoroscopic guided naso-enteric placement for stenting and decompression has been used in mechanical enteric limb obstruction after gastrectomy or gastric bypass surgery. However, the use of double naso-enteric tube for treatment of multiple enteric limbs obstruction has not been described to date. We present a 61-year-old female with afferent limb syndrome with concomitant efferent limb obstruction which caused by kinking of anastomosis after loop gastrojejunostomy for benign gastric outlet obstruction.

pH homeostasis is crucial for spermatogenesis, sperm maturation, sperm physiological function, and fertilization in mammals. HCO and H are the most significant factors involved in regulating pH homeostasis in the male reproductive system. Multiple pH-regulating transporters and ion channels localize in the testis, epididymis, and spermatozoa, such as HCO transporters (solute carrier family 4 and solute carrier family 26 transporters), carbonic anhydrases, and H-transport channels and enzymes (e.

- Afferent loop syndrome is a rare complication that can occur after upper gastrointestinal bypass surgeries, typically within two weeks, but this case shows it happened almost a decade later in a 54-year-old woman.* -
- The patient experienced symptoms like epigastric pain, vomiting, and constipation, and tests revealed a high-grade bowel obstruction related to her previous surgeries.* -
- She was treated conservatively with rehydration and a nasogastric tube, and was discharged after five days, highlighting the need for better guidelines on managing this syndrome after such surgeries.*
Hyperthermic pressurized intraperitoneal aerosol drug delivery system in a large animal model: a feasibility and safety study.

Background: We developed a novel drug delivery system called hyperthermic pressurized intraperitoneal aerosol chemotherapy (HPIPAC) that hybridized Hyperthermic intraperitoneal chemotherapy (HIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC). The present study aims to assess the feasibility and safety of HPIPAC system in a large animal survival model.
Methods: Eleven pigs (eight non-survival models and three survival models) were used in the experiment.
