- BackgroundIt is well established that the use of a postoperative drain after chronic subdural hematoma surgery reduces recurrence rates, and it is common to use a postoperative drain for longer than 24 h. It is unclear whether this is superior to a shorter drainage time of less than 24 h. Our aim was to compare a postoperative drainage longer or shorter than 24 h after chronic subdural hematoma evacuation.Materials and methodsIn this retrospective single centre study, 207 adult patients undergoing chronic subdural hematoma evacuation with a postoperative drainage longer (LDT-group) or shorter (SDT-group) than 24 h were compared regarding recurrence, mortality within 6 months and complications requiring hospital admission within 30 days. Length of hospital stay was also recorded. An active subgaleal drain was used. In addition to the retrospective cohort, we also studied the total volume drained per hour after cSDH surgery in a prospective cohort of 10 patients.ResultsRecurrence occurred in 12/96 (12.5%) in the LDT-group and in 13/111 (11.7%) patients in the SDT-group (p = 0.15). There was no significant difference between groups regarding recurrence, complications or mortality. The prospective cohort showed that most of the drainage occurred within the first hours after surgery.ConclusionOur data show that a postoperative drainage duration of less than 24 h does not lead to an increase in recurrence, complications or mortality compared to a drainage time of more than 24 h. A shorter drainage duration (< 24 h) after cSDH surgery facilitated earlier mobilisation and shorter hospital stay.

- Total parenteral nutrition (TPN) is often crucial for patients not being able to feed enterally or having intestinal absorptive deficits. Enteral nutrition is, however, frequently regarded vital for maintaining functional and structural intestinal integrity. The aim of this study was to investigate possible effects of TPN on rat distal small intestine compared to enterally fed identically housed controls, regarding the enteric nervous system (ENS), motility in vitro, and morphology. This study shows that motor responses evoked by electrical stimulation or exposure to vasoactive intestinal peptide (VIP), pituitary adenylate cyclase activating peptide-27 (PACAP-27), and nitric oxide (NO) donor were unchanged. By using immunohistochemistry, the numbers of submucous (P < 0.05) and myenteric (P < 0.05) nerve cells were found to increase, expressed as numbers per unit length. The percentage of neurons expressing VIP, PACAP-27, NO-synthase, and galanin remained unchanged, however. By in situ hybridization the number of submucous neurons expressing neuropeptide Y-mRNA was found to decrease (P < 0.05); the other populations were unaltered. Morphometry revealed an increased submucosal thickness (P < 0.05), while intestinal circumference markedly decreased (P < 0.0001) in TPN-treated rats. In conclusion, TPN treatment resulted in reduced intestinal circumference leading to condensation of enteric neurons. No marked changes in neurotransmitter expression of the enteric neurons or in motor activity were noted.

- Chromosome banding analysis of 11 short-term cultured gallbladder carcinomas revealed acquired clonal aberrations in seven tumors (five primary and two metastases). Three of these had one clone, whereas the remaining four were cytogenetically heterogeneous, displaying two to seven aberrant clones. Of a total of 21 abnormal clones, 18 had highly complex karyotypes and three exhibited simple numerical deviations. Double minutes and homogeneously staining regions were observed in one and two carcinomas, respectively. To characterize the karyotypic profile of gallbladder cancer more precisely, we have combined the present findings with our three previously reported cases, thereby providing the largest cytogenetic database on this tumor type to date. A total of 287 chromosomal breakpoints were identified, 251 of which were found in the present study. Chromosome 7 was rearranged most frequently, followed by chromosomes 1, 3, 11, 6, 5, and 8. The bands preferentially involved were 1p32, 1p36, 1q32, 3p21, 6p21, 7p13, 7q11, 7q32, 19p13, 19q13, and 22q13. Nine recurrent abnormalities could, for the first time, be identified in gallbladder carcinoma: del(3)(p13), i(5)(p10), del(6)(q13), del(9)(p13), del(16)(q22), del(17)(p11), i(17)(q10), del(19)(p13), and i(21)(q10). The most common partial or whole-arm gains involved 3q, 5p, 7p, 7q, 8q, 11q, 13q, and 17q, and the most frequent partial or whole-arm losses affected 3p, 4q, 5q, 9p, 10p, 10q, 11p, 14p, 14q, 15p, 17p, 19p, 21p, 21q, and Xp. These chromosomal aberrations and imbalances provide some starting points for molecular analyses of genomic regions that may harbor genes of pathogenetic importance in gallbladder carcinogenesis.

Cytogenetic abnormalities in a hemangiopericytoma of the spleen.

- To date, only 16 cytogenetically abnormal hemangiopericytomas (HP) have been reported. Despite this low number, some characteristic karyotypic features have already emerged: most HP are near-diploid and breakpoints in 12q13, 12q24, and 19q13 seem to be common, with t(12;19)(q13;q13) being a recurrent translocation. Here, we report the first case of a probably benign splenic HP with chromosomal abnormalities. The abnormal karyotype was 47,XX,t(5;22;11)(q31;q11;q13),+10. None of these abnormalities have previously been reported in HP, suggesting that the karyotypic pattern of splenic HP may differ from soft tissue HP.

- BACKGROUND: We have conducted a randomized controlled trial of totally extraperitoneal hernia repair (TEP) versus tension-free open repair (Lichtenstein repair); we have presented the results previously up to 1 year after the operation. The aim of this study was to compare patient outcome in both groups at a median follow-up of 7.3 years after operation. METHODS: Of 168 patients included in a prospective, randomized controlled trial designed to compare TEP with an open tension-free technique, 154 patients (92%) answered a questionnaire and 147 patients (88%) were followed up at an outpatient clinic after a minimum of 6 years after operation. RESULTS: Overall, 89% of patients in the TEP group and 95% of patients in the open group reported complete long-term recovery (P = .23). Permanent impaired inguinal sensibility was more common in the open group (P = .004), whereas the proportion of patients with reported testicular pain was higher in the TEP group (P = .003). Three recurrences were found in the TEP group, and 4 recurrences were found in the open group (P = .99). Four patients in the TEP group underwent operations for complications related to the hernia repair (small bowel obstruction, umbilical hernia, testicular pain, and neuralgia). CONCLUSION: Overall, both groups showed good long-term results with low rates of recurrences. However, the TEP group was associated with a higher proportion of patients with long-term testicular pain, whereas impaired inguinal sensibility was more common in the open group.

- Purpose The purpose of the present study was to explore the risk for complications and reoperations following open repairs for sliding groin hernias.Method All primary indirect inguinal hernia repairs registered in the Swedish Hernia Register 1998–2011 were identified. Repeated and bilateral procedures were excluded. The epidemiology, the incidence of per- and postoperative complications, and the reoperation rate due to recurrences were analyzed.Results 100 240 non-repeated unilateral repairs were registered with sliding hernias in 13 132 (13.1 %) (male 14 %, female 5 %) procedures. The methods of repair for sliding and non-sliding hernias were Lichtenstein and other open anterior mesh repairs (N = 10865, 82.7 % and N = 60790, 69.8 %), endoscopic techniques (N = 136, 1.0 % and N= 4352, 5.0 %), and other techniques (N= 2131, 16.2 % and N= 21966, 25.2 %). In multivariate analyses with adjustment for gender, acute/planned surgery, reducibility, method of repair and age, sliding hernias were associated with a low but slightly increased risk for perioperative complications (hazard ratio 1.30, 95 % confidence interval 1.04–1.62, p = 0.023) and postoperative hematoma (hazard ratio 1.13, confidence interval 1.02–1.26, p =0.019). There was no increased risk of reoperation due to recurrences.Conclusion Compared to older reports, the incidence of repairs due to primary indirect sliding inguinal hernias has increased over time and it is not just a male disease. The overall results are good with low and comparable complication rates, and no increased risk of reoperations due to recurrences.
