The use of Seprafilm at the sites of myotomies significantly reduced the incidence of adhesions. Effectiveness at the enterotomy site may have been attenuated by a greater inflammatory response. Importantly, Seprafilm did not increase septic mortality in any group.
PurposeThis study evaluated the use of adding morphine to bupivacaine in spinal anesthesia for pain control in patients who underwent an open hemorrhoidectomy.MethodsForty patients were prospectively selected for an open hemorrhoidectomy at the same institution and were randomized into two groups of 20 patients each: group 1 had a spinal with 7 mg of heavy bupivacaine associated with 80 µg of morphine (0.2 mg/mL). Group 2 had a spinal with 7 mg of heavy bupivacaine associated with distilled water, achieving the same volume of spinal infusion as that of group 1. Both groups were prescribed the same pain control medicine during the postoperative period. Pain scores were evaluated at the anesthetic recovery room and at 3, 6, 12, and 24 hours after surgery. Postoperative complications, including pruritus, nausea, headaches, and urinary retention, were also recorded.ResultsThere were no anthropometric statistical differences between the two groups. Pain in the anesthetic recovery room and 3 hours after surgery was similar for both groups. However, pain was better controlled in group 1 at 6 and 12 hours after surgery. Although pain was better controlled for group 1 after 24 hours of surgery, the difference between the groups didn't achieved statistical significance. Complications were more common in group 1. Six patients (6/20) presented coetaneous pruritus and 3 with (3/20) urinary retention.ConclusionA hemorrhoidectomy under a spinal with morphine provides better pain control between 6 and 12 hours after surgery. However, postoperative complications, including cutaneous pruritus (30%) and urinary retention (15%), should be considered as a negative side of this procedure.
Over the past several years numerous cases of port site tumor recurrence after laparoscopic resection of a cancerous tissue have been reported. Possible mechanisms for tumor seeding include tumor removal, contaminated instruments, pneumoperitoneum, and aerosolization of tumor cells. This experiment examined the relationship among trocar contamination, aerosolization, and tumor recurrence with increasing pneumoperitoneal pressure using a hamster model. Increased pneumoperitoneal pressure significantly increased both instrument contamination and tumor recurrence at midline and port site incisions. Interestingly, increasing pneumoperitoneal pressure had no significant effect on the number of aerosolized tumor cells. The results reaffirm that the use of a reduced pneumoperitoneum or gasless laparoscopy may significantly lower port site tumor recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
