- BACKGROUND: Patients with severe acute lung injury (ALI) have been treated compassionately on doctors' initiative with inhaled nitric oxide (INO) in Sweden and Norway since 1991. In 1994 the previously used technical grade nitric oxide was replaced by medical grade nitric oxide. METHODS: We have carried out a retrospective data collection on all identified adult patients treated with INO for >4 h during the period 1991-1994 focusing on safety aspects and patient outcome. We used the following exclusion criteria (1) Age <18 years, (2) Simultaneous treatment with extracorporeal removal of CO2 (3) NO inhalation period <4 h, (4) Incomplete or missing patient charts, (5) Use of INO in order to treat pulmonary hypertension following cardiac surgery, with little or no acute lung injury. RESULTS: Inclusion criteria were met by 56 out of 73 identified patients. Mean age was 48+/-19 years and the median duration of INO treatment was 102 h. PaO2/FIO2 ratio at start of treatment was 85 +/- 33 mm Hg with a lung injury score (LIS) of 3.2+/-0.8. The aetiology of the lung injury was pneumonia (n= 27), sepsis (n=12) and trauma (n=8). Survival to hospital discharge was 41% and survival after 180 d was 38%. Three serious adverse events were identified, two from technical failures of the INO delivery device and one withdrawal reaction necessitating slow weaning from INO. No methaemoglobin values >5% were reported during treatment. CONCLUSION: The overall mortality did not differ dramatically from historical controls with high mortality. Only a randomised study may determine whether INO as an adjunct to treatment alters the outcome in severe ALI. One cannot at present advocate the routine use of INO in patients with ALI outside such studies.

- 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.

- Background: The Shouldice technique is the 'gold standard' of open non-mesh hernia repair. The aim of this study was to compare 5-year recurrence rates after Shouldice and laparoscopic transabdominal preperitoneal patch (TAPP) repair for primary inguinal hernia. Method: Men with a primary unilateral inguinal hernia were randomized to either Shouldice or TAPP operation. An independent observer scored the surgeons' performance. Follow-up comprised clinical examination after 1 year, a questionnaire after 2 and 3 years, and a clinical examination after 5 years. Results: Between February 1993 and March 1996, 1183 patients were included. Nine hundred and twenty patients were followed for 5 years, 454 in the TAPP group and 466 in the Shouldice group. Recurrences were evenly distributed between groups throughout the follow-up period. The cumulative recurrence rate after 5 years was 6.6 per cent in the TAPP group and 6.7 per cent in the Shouldice group. Postoperative pain was a risk factor for recurrence after Shouldice operation but not after TAPP repair. There was a correlation between a low surgeon's performance score and recurrence. Conclusion: The 5-year recurrence rate is acceptable, with no difference between TAPP and Shouldice repair. Poor operative performance resulted in a higher recurrence rate. The TAPP operation represents an excellent alternative for primary inguinal hernia repair.

- Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-up suggests benefits for those patients operated with a laparoscopic approach compared with open techniques; ie, less postoperative pain and a shorter convalescence period. Long-term results, however, are less well known. Methods: The study was conducted as a multicenter randomized trial with a 5-year follow-up. A total of 1512 men aged 30 to 70 years, with a primary unilateral inguinal hernia, were randomized to either TEP or Lichtenstein repair. Results: Overall, 665 patients in the TEP group and 705 patients in the Lichtenstein group were evaluable. The cumulative recurrence rate was 3.5% in the TEP group and 1.2% in the Lichtenstein group (P = 0.008). Test for heterogeneity revealed significant differences between individual surgeons. The exclusion of 1 surgeon, who was responsible for 33% (7 of 21) of all recurrences in the TEP group, lowered the cumulative recurrence rate to 2.4% in this group, which was not statistically different from that of the Lichtenstein group. Conclusions: The recurrence rate for both TEP and Lichtenstein repair was low. A higher cumulative recurrence rate in the TEP group was seen at 5 years. Further analysis revealed that this could be attributable to incorrect surgical technique.

- Background: Laparoscopic appendectomy (LA) has been associated with a faster recovery and less postoperative pain than the open technique. However, few data are available on the clinical outcome of LA in overweight patients. Methods: A group of 106 patients with a body mass index (BMI) > 26.4, representing the upper quintile of 500 prospectively randomized patients, were included in the study. They were randomized to undergo either laparoscopic or open appendectomy (OA). Operating and anesthesia times, postoperative pain, complications, hospital stay, functional index (1 week postoperatively), sick leave, and time to full recovery were documented. Results: In OA, the operating time for overweight patients was significantly longer than that for patients in the normal weight range (40 vs 35 min, p < 0.05). In LA, there was no difference in operating time between the normal and overweight patients. Overweight patients who underwent LA had longer operating and anesthesia times than their OA counterparts (55 vs 40 min, p < 0.001, and 125 vs 100 min, p < 0.001, respectively). Postoperative pain was significantly greater in overweight patients who underwent OA than in those treated with the laparoscopic technique. Postoperative pain was also significantly greater in overweight patients subjected to OA than in patients of normal weight after 4 weeks, the clinical significance may, however, be of less importance since the values are low (0.26 vs 0.09, p < 0.05). There were no significant differences between the two operating techniques in terms of complications. Hospital stay was longer for overweight patients than for normal-weight patients undergoing OA (3.0 vs 2.0, p < 0.01). The functional index did not differ between any group of patients. Sick leave was longer for overweight patients who underwent OA than for normal-weight patients treated with the same technique (17 vs 13 days, p < 0.01). In the laparoscopic group, however, there were no differences between the overweight and normal-weight patients. Time to full recovery was greater in overweight patients subjected to OA than in the overweight patients in the LA group (22 vs 15 days, p < 0.001). Conclusion: In this study, overweight patients who were submitted to LA had less postoperative pain and a faster postoperative recovery than overweight patients who had OA. LA also abolished some of the negative effects that overweight had on operating time, hospital stay, and sick leave with the open technique. However, anesthesia and operating times were significantly longer in LA for both overweight patients and those with a normal BMI.
