Randomized Controlled Trial Comparative Study Clinical Trial[A concept for decreasing postoperative pain after inguinal hernia operation].
In Germany approximately 150,000 inguinal hernias are surgically corrected every year. In addition to developing an optimum operation technique it is also the responsibility of a surgeon to treat pain during and after surgery. In a prospective random double-blind study, the pain after herniotomy performed with intraoperative anesthesia of the ilioinguinal and iliohypogastric nerves with a long-acting local anesthetic combined with a vasoconstrictor was compared by means of scores on a scale from 1 to 10 with pain in a control group. ⋯ An optimum pain therapy therefore has to start during surgery. Use of a local anesthetic is especially suitable. Side effects of systemic analgesics are avoided, and perioperative risks of ambulant hernia surgery can be reduced.

Review Case ReportsPerforation of the cecum by a toothpick. Case report and review of the literature.
Perforation of the colon can have any number of causes. Most often, it is the result of carcinoma or diverticulitis; specific inflammatory disease of the large intestine is a less common cause. Other possibilities are iatrogenic perforation, perforation as a result of blunt or penetrating abdominal trauma, and ingestion of a foreign body. A case of perforation of the cecum by a toothpick 3 weeks after consumption of a beef olive is reported; possible diagnostic problems, other conditions that need to be considered in the differential diagnosis and treatment are discussed.

[Experimental studies of laparoscopically-assisted rectum resection with colo-anal or colorectal anastomosis].
A minimally invasive procedure for radical resection of tumors in the deep rectum without laparoscopic anastomosis was developed in seven domestic pigs. The length of resected rectosigmoid and mesenterium was adequate on all oncologic counts.

Comparative Study[Pressure-volume analysis of wound suction drainage containers and suction capacity of drainage tubes].
Four low-vacuum systems and eight high-vacuum systems were examined with special reference to the pressure-volume relations. The maximum filling volume for adequate transport of wound secretion was determined for each type. The use of a synthetic wound fluid instead of water resulted in a smaller aspiration volume. ⋯ The suction maximum of normal tubes and silicon tubes was located at the proximal holes of the perforated tubes. The "Ulm drain," with perforation diameter increasing continuously to the distal end of the tube, was found to exert suction even at the more distal part of the tube. It is estimated that this tube allows locally more balanced vacuum in the wound.
