Recurrent incisional hernia repair: surgical outcomes in correlation with body-mass index.

BACKGROUND: Hernia recurrence rates after incisional hernia repair vary between 8.7 and 32%, depending on multiple factors such as patient characteristics, the use of meshes, surgical technique and the degree of experience of the treating surgeon. Recurrent hernias are considered complex wall hernias, and 20% of all incisional hernia repairs involve a recurrent hernia. The aim of this study was to investigate the outcomes after recurrent incisional hernia repair, in association with surgical technique and body-mass index (BMI). METHODS: All patients who had incisional hernia repair between 2013 and 2018 were included. Primary outcome was rate of recurrent incisional hernia after initial hernia repair. Secondary outcomes were complication rate and recurrence rate in association with BMI. RESULTS: A number of 269 patients were included, of which 75 patients (27.9%) with a recurrent incisional hernia. Recurrent hernia repair was performed in 49 patients, 83.7% underwent open repair. Complication rate for recurrent hernia repair was higher than for the initial incisional hernia repair. Of the 49 patients with recurrent hernia repair, patients with a BMI above 30 had higher complication and recurrence rates compared to patients with BMI below 30. Especially infectious complications were more common in patients with a higher BMI: 23.1% vs. 0% wound infections. CONCLUSION: The results from this study show that complication and recurrence rates are increased after recurrent incisional hernia repair, which are further increased by obesity. Only a limited amount of literature is available on this topic, further larger multicenter studies are necessary, until then a patient-specific surgical approach based on the surgeon's expertise is recommended.

Perioperative monitoring of inguinal hernia patients with a smartphone application.

INTRODUCTION: Patient Reported Outcomes have become standard in the evaluation of inguinal hernia repair. However, the chosen outcomes remain heterogeneous and the measurements time-consuming or inadequate. Perioperative measurement of pain and recovery could benefit from the contemporary possibilities that mobile health applications offer. METHODS: An application for smartphones and tablets was developed using the twitch crowdsourcing concept, classical questionnaires, experiences from randomised clinical trials, and patients' input. RESULTS: Dichotomous questions and numeric rating scales, both pre- and post-operative, were implemented in the freely available Q1.6 application. Content, timing and frequencies were adapted to the inguinal hernia patient's daily life and assumed recovery. Certain combinations of answers were set as alert notifications to detect adverse events. Data are displayed on a web-based dashboard enabling real-time monitoring. Legal aspects were examined and taken into account. DISCUSSION: The Q1.6 inguinal hernia app is an innovative tool for perioperative monitoring of pain and recovery of inguinal hernia patients. Previous limitations of classical measurements such as a large heterogeneity, retrospective data recording and different forms of bias can be eliminated. The `big data´ generated in this manner might be used for large-scale research to improve inguinal hernia surgery. The Q1.6 platform is not only hernia specific; it is also an innovative tool to measure PROs in any other domain.

Outcomes of surgery on patients with a clinically inapparent inguinal hernia as diagnosed by ultrasonography.

BACKGROUND: Chronic post-operative inguinal pain (CPIP) is the most significant complication following inguinal hernia repair. Patients without a palpable hernia prior to surgery seemed to report more CPIP. Our aim was to evaluate the effects of surgery on patients with a clinically inapparent inguinal hernia as diagnosed using ultrasonography. METHODS: A total of 179 hernia repairs in patients with a positive ultrasonography but negative physical examination were analysed retrospectively. Patients with recurrent hernias, femoral hernias or previous surgery to the inguinal canal were excluded. The primary outcome was the presence of chronic postoperative inguinal pain (pain > 3 months postoperatively). Data on preoperative complaints, surgical technique and findings during ultrasonography and surgery were also studied in relation to the development of CPIP. RESULTS: A quarter (25.1%) of the patients reported chronic postoperative pain. Female gender (p = 0.03), high BMI (p = 0.04) and atypical symptoms prior to surgery (p < 0.001) were significant univariate risk factors for developing CPIP. Logistic regression showed a significant association between atypical symptoms and CPIP [OR = 6.31, p < 0.001, 95% CI (2.32, 17.16)], which was still present after correction for the significant univariate variables [OR = 4.23, p = 0.02, 95% CI (1.26, 14.21)]. CONCLUSION: Patients with a clinically inapparent inguinal hernia as diagnosed using ultrasonography report a high incidence of CPIP after elective hernia repair. Patients with atypical groin pain prior to surgery are especially prone to CPIP. It is questionable whether these hernias should be classified and treated as symptomatic inguinal hernias. The results advocate taking other causes of groin pain into consideration before choosing surgical treatment.

Rapid identification of Candida spp. in peritonitis patients by Raman spectroscopy.

This prospective study evaluated Raman spectroscopy for the identification of clinically relevant Candida spp. in peritonitis patients. A Raman database was developed by measuring spectra from 93 reference strains belonging to ten different Candida spp. Clinical samples were obtained from the surgical department and intensive care unit of a tertiary university hospital. In total, 88 peritoneal specimens from 45 patients with primary, secondary or tertiary peritonitis were included. Specimens were cultured initially on a selective Sabouraud medium that contained gentamicin to suppress bacterial growth. For conventional identification, a chromogenic medium was used for presumptive identification, followed by use of the Vitek 2 system for definitive identification (requiring a total time of 48-96 h). Raman measurements were taken on overnight cultures from Sabouraud-gentamicin medium. Thirty-one samples were positive for Candida by culture. Using multivariate statistical analyses, a prediction accuracy of 90% was obtained for Raman spectroscopy, which appears to offer an accurate and rapid (12-24 h) alternative for the identification of Candida spp. in peritonitis patients. The reduced turn-around time is of great clinical importance for the treatment of critically ill patients with invasive candidiasis in intensive care units.

[NSAID-use delays the diagnosis of 'acute abdomen']. / NSAID-gebruik vertraagt de diagnose 'acute buik'.

In three patients with abdominal pain, two men aged 63 and 18 years and a woman aged 46 years, the use of NSAIDs reduced the symptoms. They were in fact suffering from peritonitis due to gastrointestinal perforation, but the decision to operate was delayed because of the relatively mild presentation. The strong analgesic, antipyretic and anti-inflammatory properties of NSAIDs can reduce the symptoms, signs and laboratory findings of peritonitis.

[Right-sided diverticulitis mimicking acute appendicitis]. / Diverticulitis dextra vermomd als appendicitis acuta.

The probability diagnosis in two patients, women aged 43 and 41 years, who for the last few days had had pain in the right lower abdomen, without nausea or vomiting, was acute appendicitis; a third patient, a woman aged 49 with the same symptoms, had undergone appendectomy in the past. Peroperative findings and, in two patients, microscopy of the resected specimen showed diverticulitis in the caecum or ascending colon. This is an uncommon disease, which mimicks acute appendicitis. Treatment depends on the severity of the inflammation. In the absence of perforation or abscess, conservative treatment suffices. Otherwise, resection of the colon is necessary.

[Dutch results of the European study of the prevalence of infections during intensive care (EPIIC). I. Who is at risk?]. / Nederlandse resultaten van het Europese prevalentieonderzoek naar infecties tijdens intensive care (EPIIC). I. Wie loopt risico?

OBJECTIVE: Evaluation of the point prevalence of infections acquired in an intensive care unit (ICU) and determination of risk factors for ICU patients. DESIGN: Descriptive study. SETTING: 78 Dutch ICUs. METHOD: Collecting data by detailed questionnaires for each patient admitted to one of the participating ICUs, on one specified day: April 29th, 1992. Follow-up lasted 6 weeks. RESULTS: Included in the study were 472 patients; 176 (37%) suffered from an infection, of which 74 (16%) was ICU-acquired. The most important risk factors were: a longer ICU stay (relative risk (RR) 4.23 (95% confidence interval: 3.32-5.40), 99.37 (22.26-434.50) and 146.79 (32.83-656.30) for ICU stays of 3-4 days, 1-2 and more than 3 weeks respectively, in comparison with 0-2 days), correlated with severity of disease (organ dysfunction) and more medical interventions (intubation, urine catheter). The ICU infection risk was lower after elective surgery than after ICU admission without surgery; after emergency surgery the ICU infection risk was higher. During follow-up 63 (14%) patients died. Patients suffering from an ICU infection had a higher mortality risk; the strongest prognostic factor in determining the mortality risk was the APACHE II score (RR: 13 (3.89-42.69) with a score between 16-26 and RR > 100 (7.67-1377.93) with score > 31). CONCLUSION: ICU-acquired infections are a serious problem. Programmes for infection prevention and control need to be adjusted.

[Dutch results of the European study of prevalence of infection during intensive care (EPIIC). II. Nature of the infections]. / Nederlandse resultaten van het Europese prevalentieonderzoek naar infecties tijdens intensive care (EPIIC). II. Aard van de infecties.

OBJECTIVE: Evaluation of the point prevalence of ICU-acquired infections, the type of infection, the bacteriological cultures and the antibiotics used. DESIGN: Point prevalence study. SETTING: 78 Dutch ICUs, as part of ICUs in 17 West-European countries. METHOD: Collecting data by detailed questionnaires for each patient admitted to one of the participating ICUs, on one specified day: April 29th, 1992. Follow-up lasted 6 weeks. RESULTS: The most frequently diagnosed ICU-acquired infections were pneumonia and infections of the lower respiratory tract (together 63%), followed by urinary tract infections (16%), sepsis (16%) and wound infections (11%). The most frequently cultured pathogens were Gram-negative bacteria (92%), especially Enterobacteriaceae (34%) and Pseudomonas aeruginosa (30%), followed by Staphylococcus (37%), Enterococcus (20%) and surprisingly: 10% fungi. The most-prescribed antibiotics were the cephalosporins (30%), followed by broad-spectrum penicillins (17%), metronidazole (17%) and aminoglycosides (13%). On the day of this survey there was in the Netherlands no infection with MRSA (Methicillin Resistant Staphylococcus aureus), although gentamicin resistant coagulase-negative Staphylococcus and ciprofloxacin-resistant P. aeruginosa were present. In most of the hospitals in the Netherlands, microbiologists, infectious disease specialists (84%) and infection control nurses (51%) take part in the ICU team. Half of the hospitals use selective decontamination. CONCLUSION: ICU-acquired infections are a real threat to the ICU patient. Despite a cautious antibiotics management in the Netherlands, resistance remains a serious problem.

[Experiences with congenital duodenal obstruction in the Sophia Kinderziekenhuis]. / Ervaringen met congenitale duodenumobstructie in het Sophia kinderziekenhuis.

In the department of Paediatric Surgery, Sophia Children's Hospital, University Hospital, Rotterdam, we investigated whether the presence of Down's syndrome influenced the chances of survival of patients with a congenital duodenal obstruction. The retrospective study comprised all 109 patients admitted to the Sophia Children's Hospital with a congenital duodenal obstruction in the period 1971-1989. The additional presence of Down's syndrome itself did not influence the prognosis. The presence of other additional anomalies (especially cardiac anomalies) did influence the mortality rate. In the past these anomalies--which are present more frequently in association with Down's syndrome--were responsible for the higher mortality in children with both a congenital duodenal obstruction and Down's syndrome. We conclude that with the availability of the current medical (especially cardio-surgical) techniques, it may be expected that the mortality rate of duodenal obstruction will be the same in patients with and without Down's syndrome (10%). Only non-medical, non-technical arguments can be of overriding importance in the decision whether a newborn child suffering from both a duodenal obstruction and Down's syndrome will or will not be operated on.
