[Peroperative "lavage" and primary anastomosis in acute left-sided colon ileus].
AIM: A description of technique, course and results of operation for left-sided obstruction of the colon with primary resection, perioperative lavage of the colon and primary anastomosis. DESIGN: Retrospective examination of case records. MATERIAL: From January 1st 1994-December 31st 1997 eight operations were performed including primary resection, perioperative lavage and primary anastomosis. RESULTS: No anastomotic leaks were found. One patient died five days postoperatively due to cardiac complications. Three patients had postoperative cardiopulmonary complications treated medically. One patient had rupture of the fascia, was reoperated, experienced wound infection, transient serum elevation of liver enzymes and underwent ERCP with papillotomy and extraction of stones from the common bile duct two months postoperatively. CONCLUSION: In this small series the technique has appeared safe, thus confirming previous reports.

[Surgical treatment of stomach cancer at a university hospital. A retrospective survey of the period 1990-1995].
AIM: A retrospective study of 69 cases of gastric cancer seen during the period from 1/1-1990 to 31/12-1994 treated in a University Hospital. The aim of the study was to describe morbidity, mortality and identify independent prognostic variables for mortality. METHOD: Patient data were recovered from the hospital's central database. Mortality was chosen as end-parameter. Univariate log-rank-test identified statistically significant variables which were then analysed by Cox backward stepwise regressional analysis. MATERIAL: Sixty-nine patients were available for analysis, median age 73 years. Fifty-one patients underwent operation. Eighteen patients did not have a surgical procedure due to disseminated disease. The overall postoperative morbidity was 25% and postoperative mortality 10%. The overall five-year survival rate was 8%, 12% for operated patients, 35% after radical and 0% after non-radical or omitted surgery. Age, radicality of operation, type of operation, Borrmann's tumour classification, and degree of depth of local infiltration were identified as significant factors for survival. Cox's analysis identified type of operation (p = 0.0002) and Borrmann's tumour classification (p = 0.001) as independent variables. DISCUSSION: The overall five-year survival is low and has not changed over two decades in Denmark, whereas mortality and morbidity rates have improved. It should be recommended that: The treatment of gastric cancer must be centralised in order to develop preoperative examinations, operative technique and the necessary routine for the surgeons. All gastric ulcers must be considered malignant and biopsies taken accordingly.

Feasibility of local infiltration anaesthesia for recurrent groin hernia repair.
OBJECTIVE: To describe the the feasibility of and patients' satisfaction with day case repair of recurrent inguinal hernias under unmonitored local anaesthesia. DESIGN: Prospective study. SETTING: Public service university hospital, Denmark. SUBJECTS: All patients with a reducible recurrent inguinal or femoral hernia unselectedly referred for elective repair during the 4-year period 1 September 1994 to 31 August 1998. INTERVENTIONS: Data were collected prospectively and consecutively from standardised, detailed files, a questionnaire 4 weeks postoperatively, and the Copenhagen Hospitals electronic patient data management system. MAIN OUTCOME MEASURES: Feasibility of local anaesthesia in the day case setting, patient satisfaction and morbidity. RESULTS: 215 consecutive operations for recurrent hernias were performed under unmonitored local anaesthesia. No conversion to general anaesthesia took place and no patients developed urinary retention. After 207 operations, the patients were discharged on the day of operation (96%), and the median time from the end of operation to discharge was 90 minutes (IQR 75-140). After 6 operations (3%), patients had complications that required surgical intervention. The 4-week questionnaire was returned after 208 operations (97%). 30 patients were dissatisfied, mainly because of intraoperative pain (17 patients, 8%). No mortality or cardiopulmonary morbidity was recorded during the first 30 days postoperatively. CONCLUSIONS: Open day-case repair of recurrent inguinal hernias can safely be conducted under unmonitored local anaesthesia with minimal morbidity. Intraoperative pain is the main topic that requires improvement.

One-thousand consecutive inguinal hernia repairs under unmonitored local anesthesia.
UNLABELLED: To evaluate the feasibility and safety of unmonitored local anesthesia (ULA) for elective open inguinal hernia repair, we made a prospective, consecutive data collection from 1000 operations on primary and recurrent hernias. Follow-up consisted of a questionnaire 1 mo after surgery and retrieval from the electronic patient data management system. In 921 ASA Group I and II and 79 ASA Group III and IV patients, the median age was 60 yr (range, 18-95 yr). ULA was converted to general anesthesia in 5 of 1000 cases, and 961 patients were discharged on the day of surgery after 95 min (median; interquartile range, 75-150); 29 patients had complications requiring surgical intervention. Within the first month, three patients died of causes unrelated to hernia surgery, and six had cardiovascular or respiratory events. The questionnaire was returned by 940 patients; 124 were dissatisfied with local anesthesia, day-case setup, or both, primarily because of intraoperative pain (n = 74; 7.8%). We conclude that open inguinal hernia repair can be conducted under ULA, regardless of comorbidity, with a small rate of deviation from day-case setup and minimal morbidity. It provides a safe alternative to other anesthetic techniques with an acceptable rate of satisfaction, but intraoperative pain relief needs improvement. IMPLICATIONS: Inguinal hernia repair can be safely performed under unmonitored local anesthesia with infrequent postoperative morbidity and acceptable satisfaction, but intraoperative pain may be a problem.

Pain after primary inguinal herniorrhaphy: influence of surgical technique.
BACKGROUND: Pain is an important problem after ambulatory hernia repair. To assess the influence of the surgical technique on postoperative pain, two separate randomized, patient-blinded, controlled trials were performed in men with an indirect inguinal hernia. STUDY DESIGN: In study A, 48 patients with an internal inguinal ring smaller than 1.5 cm were randomly allocated to either simple extirpation of the hernial sac or extirpation plus annulorrhaphy. In study B, 84 patients with an internal inguinal ring wider than 1.5 cm were randomly allocated to extirpation plus annulorrhaphy or extirpation plus Lichtenstein mesh repair (modified). All operations were performed under unmonitored local anesthesia with standardized perioperative analgesia using methadone and tenoxicam. Pain was scored daily for the first postoperative week and after 4 weeks on a four-point verbal-rank scale (no, light, moderate, or severe pain) during rest, while coughing, and during mobilization (rising to the sitting position). Use of supplementary analgesics (paracetamol) was recorded. Cumulative daily pain scores for the first postoperative week and the number of patients who used supplementary analgesics were the main outcome measures. RESULTS: There were no significant differences in cumulative pain scores or use of supplementary analgesics between the treatment groups in either study. Cumulative pain scores were significantly higher during coughing and mobilization than during rest in both studies. CONCLUSIONS: Choice of surgical technique for open repair of a primary indirect inguinal hernia has no influence on postoperative pain.

Prospective study of chronic pain after groin hernia repair.
BACKGROUND: The aim was to provide a detailed description of any residual pain 1 year after elective day-case open groin hernia repair under local anaesthesia. METHODS: This was a prospective consecutive case series study by questionnaire of 500 consecutive operations in 466 unselected adult patients 1 year after surgery. Pain was scored (none, mild, moderate or severe) at rest, while coughing and during mobilization, and compared with similar data collected 1 and 4 weeks after operation. RESULTS: Some 419 questionnaires were returned (response rate 93 per cent); 20 patients had died within the year and 30 data sets from patients who had a subsequent operation during the study were excluded. Eighty patients (19 per cent) reported some degree of pain, and 25 (6 per cent) had moderate or severe pain. Pain restricted daily function in 24 patients (6 per cent). The incidence of moderate or severe pain was higher after repair of recurrent than primary hernias (14 versus 3 per cent; P < 0.001). The risk of developing moderate or severe pain was increased in patients who had a high pain score 1 week after operation (9 versus 3 per cent; P < 0.05) and also in patients who had moderate or severe pain 4 weeks after operation (24 versus 3 per cent; P < 0.001). CONCLUSION: Chronic pain is a significant problem after open groin hernia repair. It may be worse after surgery for a recurrent hernia and may be predicted by the intensity of early postoperative pain.

Short convalescence after inguinal herniorrhaphy with standardised recommendations: duration and reasons for delayed return to work.
OBJECTIVE: To provide a detailed description of post-herniorrhaphy convalescence. DESIGN: Prospective, descriptive, consecutive questionnaire case series. SETTING: Public university hospital, Denmark. PATIENTS: 100 consecutive patients treated for inguinal hernia. INTERVENTION: Elective open inguinal herniorrhaphy under local anaesthesia. One day convalescence for light/moderate and three weeks for strenuous physical activity was recommended. MAIN OUTCOME MEASURE: Duration of absence from work or main recreational activity. RESULTS: Overall median absence (including the day of operation) was 6 days (interquartile range 1-16). For unemployed patients it was 1 day (0-7), for patients with a light or moderate workload 6 days (3-12), and for those with a heavy workload 25 days (21-37). Among the 64 patients, who did not follow the recommendations, pain was contributory in 33 and advice from the general practitioner in 12. Pain was the main cause of impairment of activities of daily living. CONCLUSION: Well-defined recommendations for convalescence may, together with improved management of postoperative pain, shorten convalescence; they are essential in the evaluation of effects of different surgical techniques of herniorrhaphy on convalescence.

Levobupivacaine vs bupivacaine as infiltration anaesthesia in inguinal herniorrhaphy.
We have compared the anaesthetic and analgesic efficacy of levobupivacaine with that of racemic bupivacaine in 66 male patients undergoing ambulatory primary inguinal herniorrhaphy. Patients were allocated randomly in a double-blind manner to local infiltration anaesthesia (0.25% w/v 50 ml) with either racemic bupivacaine (n = 33) or levobupivacaine (n = 33). Scores for intraoperative pain and satisfaction with anaesthesia were recorded, together with perception of postoperative pain and need for supplementary postoperative analgesic medications in the first 48 h after operation. Intraoperative satisfaction with the infiltration anaesthesia was similar, with median scores of 77 (levobupivacaine) and 80 (bupivacaine) (VAS; 100 mm = extremely satisfied). Time averaged postoperative pain scores (48 h) were 8 (levobupivacaine) and 10 (bupivacaine) in the supine position, 13 (levobupivacaine) and 12 (bupivacaine) while rising from the supine position to sitting, and 9 (levobupivacaine) and 13 (bupivacaine) while walking (VAS; 100 mm = worst pain imaginable) (ns). There was no difference in the use of peroral postoperative analgesics between the two groups. We conclude that racemic bupivacaine and its S-enantiomer levobupivacaine had similar efficacy when used as local infiltration anaesthesia in inguinal herniorrhaphy.

[Organization and results of ambulatory surgery for inguinal hernia].
The results of a reorganization of surgery for inguinal hernias within a department of surgical gastroenterology were assessed concerning staff simplifications, feasibility, patient satisfaction, safety, complications and resources. Five hundred consecutive, elective, open operations for unilateral reducible inguinal hernias were performed in 466 patients under local anaesthesia in an ambulatory setup. One hundred and fourteen of the operations were for a recurrent hernia. The median age was 60 years (44-74 years as 25% and 75% quartiles). Two of the operations were converted to general anaesthesia. The patients were discharged 85 min (median) post-operatively, but 12 patients were not discharged on the same day. Bleeding or wound infections in need of treatment were seen postoperatively in 1.6% and 1.6%, respectively. All patients were given a postoperative questionnaires with a response rate of 95%, 89% of the respondents were satisfied with the whole procedure, 11% were dissatisfied. A reorganization of surgery for inguinal hernias to a standardized ambulatory setup induced staff simplifications and saved resources with a preserved high patient satisfaction, safety and a low complication rate.

Pain after groin hernia repair.
BACKGROUND: The purpose of the study was to provide a detailed description of postoperative pain after elective day-case open inguinal hernia repair under local anaesthesia. METHODS: This was a prospective consecutive case series study. After 500 hernia operations in 466 unselected patients aged 18-90 years, pain was scored (none, light, moderate or severe) at rest, while coughing and during mobilization, daily for the first postoperative week and after 4 weeks. Pain scores were added together over the first postoperative week. RESULTS: On days 1, 6 and 28, 66, 33 and 11 per cent respectively had moderate or severe pain while coughing or mobilizing. Total pain scores were higher while coughing or mobilizing than at rest (P < 0.001). Younger patients had higher total pain scores than older patients while coughing or mobilizing (P0< 0.01), but not at rest. No significant differences were found between types of surgery or hernia. CONCLUSION: Pain remained a problem despite the pre-emptive use of opioids, non-steroidal anti-inflammatory drugs and local anaesthesia, irrespective of surgical technique.

Cryoanalgesia: effect on postherniorrhaphy pain.
UNLABELLED: Cryoanalgesia versus sham treatment was applied to the ilioinguinal and iliohypogastric nerves after mesh repair of an inguinal hernia under local anesthesia in 48 male patients in a prospective, randomized, and observer- and patient-blinded trial. Pain was scored daily during rest, while coughing, and during mobilization to the sitting position for 1 wk and weekly for 8 wk on a four-point verbal rank scale. Use of supplementary analgesics and sensory disturbances were recorded. Assessments were made for allodynia, hyperalgesia, and mechanical pain detection thresholds 8 wk postoperatively. Cumulative pain scores for the first postoperative week were equal in the two groups, as was the use of analgesics. Eight weeks postoperatively, three cases of hyperalgesia to pinprick were detected in the cryoanalgesia group, and 10 patients in the cryoanalgesia group versus 5 in the sham-treatment group reported disturbed sensibility. We conclude that cryoanalgesia of the iliohypogastrical and ilioinguinal nerve does not decrease postherniorrhaphy pain. IMPLICATIONS: Does freezing of sensory nerves in the groin reduce pain after hernia repair? Extreme cold (-60 degrees C) was applied in a double-blind, randomized study. No difference in pain scores was found. Sensory disturbances were seen in treatment and control patients. Freezing cannot be recommended for pain relief after hernia repair.

The feasibility, safety and cost of infiltration anaesthesia for hernia repair. Hvidovre Hospital Hernia Group.
Data from 400 consecutive elective ambulatory operations for inguinal hernia under unmonitored local anaesthesia with limited pre-operative testing were prospectively obtained by the use of standardised files and questionnaires to assess the feasibility, patient satisfaction and potential cost reductions for such a technique. The median age of the patients was 59 years, and 29 operations were performed in ASA group III patients. The median postoperative hospital stay was 85 min. Conversion to general anaesthesia was necessary only in two cases, and nine patients needed overnight admission. One week postoperative morbidity was low with one case of transient cerebral ischaemia and one case of pneumonia, but no case of urinary retention. On follow-up, 88% were satisfied with the procedure, including unmonitored local anaesthesia. The cost reduction was at least 160 Pounds per patient compared with general/regional anaesthesia. We conclude that elective inguinal herniorrhaphy may be performed routinely under unmonitored local anaesthesia with a low postoperative morbidity, a high satisfaction rate and significant cost reductions.

[Segmental "portal hypertension". A rare cause of severe tractable variceal bleeding].
We present a 33 year-old man with massive upper gastrointestinal bleeding caused by a rare form of segmental portal hypertension. The patient developed a pancreatic abscess, which caused an isolated thrombosis in the splenic vein and the development of pronounced collaterals and bleeding fundus varices. The patient underwent splenectomy and recovered quickly hereafter. The literature is sparse on severe bleeding complications due to acute pancreatitis. The present case emphasizes the importance of recognition of unusual manifestations of common clinical conditions.

[Recurrence of inguinal hernia: ambulatory surgery under local anesthesia].
In order to assess the feasibility of repair of a recurrent inguinal hernia in unmonitored local anaesthesia in an ambulatory set-up pain scores and data on patient satisfaction were obtained from 76 unselected patients after 79 consecutive operations. Median age was 63 years, and 25%- and 75% quartiles were 49 and 72 years respectively. All operations were conducted in local anesthesia. Three patients stayed in hospital overnight after the operation. Pain: After one, six and 28 days 27, 14 og 7% respectively had severe pain during function (cough and/or rising). Satisfaction: 82% were satisfied with ambulatory surgery in local anaesthesia, 82% were satisfied with the analgesic therapy (tenoxicam and methadone), but one third needed supplementary analgesics during the first week (acetaminophen was recommended). It is concluded, that ambulatory repair of a recurrent inguinal hernia in unmonitored local anaesthesia is a safe and cost effective alternative to operation in general or spinal anaesthesia.

Human thyroid epithelial cells cultured in monolayers. I. Decreased thyroglobulin and cAMP response to TSH in 12-week-old secondary and tertiary cultures.
An in vitro system of secondary and tertiary cultures of human thyroid epithelial cells (TFECs) in monolayer is described. The function of the cells was evaluated by the second messenger cAMP and the end product thyroglobulin (Tg). The Tg production from the cells was measured in the supernatant by a newly developed enzyme-linked immunosorbent assay. The TFECs in secondary monolayer cultures had preserved the ability to produce Tg and cAMP despite lack of polarization. Furthermore, a preserved ability of TSH-stimulated production of Tg and cAMP in 12-week-old secondary and tertiary cultures was found. However, the Tg and cAMP levels decreased gradually with the age of the cultures. In the secondary culture the TSH-stimulated Tg production decreased from 253 ng/micrograms DNA (205-263) after 3 weeks to 18 ng/micrograms DNA (6-81), P < 0.001, n = 6 after 12 weeks and TSH-stimulated cAMP production from 660 pmol/micrograms DNA (500-840) to 60 (40-200), P < 0.001, n = 6. The decreased responsiveness of long-term cultures results in preference of short-term secondary cultures, which provide a more suitable experimental model for in vitro investigation of human thyroid cell functions.
