- BACKGROUND: The optimal treatment for recurrent inguinal hernia is of concern due to the high frequency of recurrence. METHODS: This randomized multicenter study compared the short- and long-term results for recurrent inguinal hernia repair by either the laparoscopic transabdominal preperitoneal patch (TAPP) procedure or the Lichtenstein technique. RESULTS: A total of 147 patients underwent surgery (73 TAPP and 74 Lichtenstein). The operating time was 65 min (range, 23-165 min) for the TAPP group and 64 min (range, 25-135 min) for the Lichtenstein group. Patients who underwent TAPP reported significantly less postoperative pain and shorter sick leave (8 vs 16 days). The recurrence rate 5 years after surgery was 19% for the TAPP group and 18% for the Lichtenstein group. CONCLUSION: The short-term advantage for patients who undergo the laparoscopic technique is less postoperative pain and shorter sick leave. In the long term, no differences were observed in the chronic pain or recurrence rate.

- Background: Laparoscopic herniorrhaphy has emerged as a recognized operative method for inguinal hernia repair. This study compared the short-term results of two tension-free methods of repair: totally extraperitoneal (TEP) laparoscopic patch repair and the open Lichtenstein mesh technique. Methods: A total of 1513 men from 11 hospitals who presented with a primary unilateral inguinal hernia were randomized to one of the two methods. Operating time, short-term complications, reoperations, postoperative pain, consumption of analgesics, sick leave and time to resumption of normal physical activities were recorded. Results: Some 1371 of the 1513 men underwent surgery, 665 in the TEP group and 706 in the Lichtenstein group. The median duration of operation was 55 min for both procedures and 91.0 per cent of die patients in both groups were discharged on the day of operation. Patients in the TEP group experienced less postoperative pain (P < 0.001), consumed fewer analgesics (P < 0.001), had a shorter period of sick leave (7 versus 12 days; P < 0.001) and a shorter time to resumption of normal physical activity (20 versus 31 days; P < 0.001). Conclusion: The TEP technique took no longer to perform, and was associated with less postoperative pain, a shorter period of sick leave and a faster recovery, compared with open Lichtenstein hernia repair.

- 1. The effects of short-term starvation and refeeding on the free amino acid concentrations of the intestinal mucosa were characterized in male subjects (n=6), using endoscopically obtained biopsy specimens from the duodenum and from all four segments of the colon.2. The alterations in the amino acid concentrations in response to short-term starvation were overall uniform in both duodenal and colonic mucosa as well as in plasma. Most amino acids decreased, whereas branched-chain amino acids increased.3. In the colon, glutamic acid and glutamine decreased during the starvation period, whereas they remained unaltered in the duodenum. This was the major difference in response to short-term starvation between the amino acid concentrations in the intestinal mucosa of the duodenum and colon.4. Refeeding for 3 days normalized the amino acid concentrations except for glutamic acid, asparagine and histidine, which remained low in the colon, and threonine, which showed an overshoot in both parts of the intestine. S. The changes in mucosal amino acid concentrations seen in response to starvation and refeeding were uniform in the four segments of the colon. This suggests that sampling from the rectum/sigmoid colon will give representative values for the free amino acid concentrations of the entire large intestine.
