Comparison of conventional and laparoscopic Hartmann's procedure reversal.

Purpose This study compares open Hartmanns procedure reversal (OHPR) and laparoscopic Hartmanns procedure reversal (LHPR) in patients first treated for peritonitis (Henchey III or IV). Methods Fourteen patients who underwent LHPR during a 2-year period were compared with 20 patients who had previously undergone an open procedure at the same institution. Results Conversion rate was 14.28%. Operating time was shorter for the laparoscopic group [143 (90 to 240) vs. 180 (90 to 350) min, P<0.05]. Hospital length of stay was shorter for the laparoscopic group [9.5 (4 to 18) vs. 11 (6 to 39)]. Use of patient-controlled analgesia was not significantly shorter in the laparoscopic group [3 (0 to 4) vs. 3.5 (0 to 8)]. Morbidities observed in the LHPR group include a parietal abscess and an anastomotic stenosis without surgical treatment. The OHPR group had 6 complications: 1 anastomotic leak and 5 incisional hernias. Conclusions LHPR with a conversion rate of 14.28% seems to be a method with shorter operating time and less morbidity compared with OHPR.

Use of intra-osseous access in adults: a systematic review

BackgroundIndications for intra-osseous (IO) infusion are increasing in adults requiring administration of fluids and medications during initial resuscitation. However, this route is rarely used nowadays due to a lack of knowlegde and training. We reviewed the current evidence for its use in adults requiring resuscitative procedures, the contraindications of the technique, and modalities for catheter implementation and skill acquisition.MethodsA PubMed search for all articles published up to December 2015 was performed by using the terms “Intra-osseous” AND “Adult”. Additional articles were included by using the “related citations” feature of PubMed or checking references of selected articles. Editorials, comments and case reports were excluded. Abstracts of all the articles that the search yielded were independently screened for eligibility by two authors and included in the analysis after mutual consensus. In total, 84 full-text articles were reviewed and 49 of these were useful for answering the following question “when, how, and for which population should an IO infusion be used in adults” were selected to prepare independent drafts. Once this step had been completed, all authors met, reviewed the drafts together, resolved disagreements by consensus with all the authors, and decided on the final version.ResultsIO infusion should be implemented in all critical situations when peripheral venous access is not easily obtainable. Contraindications are few and complications are uncommon, most of the time bound to prolonged use. The IO infusion allows for blood sampling and administration of virtually all types of fluids and medications including vasopressors, with a bioavailability close to the intravenous route. Unfortunately, IO infusion remains underused in adults even though learning the technique is rapid and easy.ConclusionsIndications for IO infusion use in adults requiring urgent parenteral access and having difficult intravenous access are increasing. Physicians working in emergency departments or intensive care units should learn the procedures for catheter insertion and maintenance, the contraindications of the technique, and the possibilities this access offers.

Validation of a performance assessment scale for simulated intraosseous access.

Abstract We propose an intraosseous (IO) procedure scale for evaluating the insertion process during simulation. A 12-item scale for assessing the performance of IO insertion into the proximal tibia reproduces all the steps of a manual procedure. The performance of 31 emergency physicians was evaluated with this scale on a mannequin simulating a decompensated shock in a 6-month-old infant. Our IO procedure scale was reliable, with a very high interobserver reproducibility. The application of this scale to procedures yielded higher scores for successful than for unsuccessful procedures (P < 10−4), a 93.5% success rate, and a mean placement time of 2 minutes 23 seconds. Although designed for a manual insertion of an IO needle during simulation, this scale may be also suitable for use in clinical settings.

Abnormalities of the gallbladder, clinical effects.

The aim of this review of the literature was to present and discuss the anatomical and embryological basis of congenital abnormalities of the gallbladder, based on a case of volvulus. In the rare cases of ectopic gallbladder, diagnosis of a biliary disease could be difficult. In such cases surgery can also be dangerous, especially when it is associated with abnormalities of the intra-hepatic biliary and vascular tree. This study, based on the embryology of the extra hepatic bile duct, focused on the most frequent gallbladder abnormalities to keep them in mind.

Parental presence during cardiopulmonary resuscitation of children: the experience, opinions and moral positions of emergency teams in France

Objective To evaluate the experience, opinions and moral positions of French emergency physicians (EP) who had taken a paediatric university course on parental presence during child cardiopulmonary resuscitation (CPR), and to compare it with the responses of nurses on their teams. Methods A questionnaire was sent to 550 EPs who had taken the course during the previous 6 years; the EPs were also asked to give a copy of the questionnaire to nurses on their staff. Data were collected on experience of parental presence during child CPR, opinions on the practice, arguments for and against parental presence, and the moral positions of respondents regarding their perception of life and the sharing of medical/parental power in the decision-making process. Results 343 responses were analysed, 47% from EPs (29% response rate) and 53% from nurses. 52% of respondents had experienced parental presence during child CPR, but it had been the physicians wish on only 6% of these occasions. Only 17% of respondents favoured parental presence, with EPs (27%) being favourable more often than nurses (12%). The reasons against parental presence were psychological trauma for the parents, risk of interference with medical management, and care team stress. Respondents not in favour of parental presence expressed this view more for medical reasons than for parent-related reasons. The physicians not in favour of parental presence espoused a moral position predicated on medical power. Conclusions A majority of EPs and nurses were reluctant to have parents present during child CPR. Their attitude involved medical paternalism.

A prospective radiological anatomical study of the variations of the position of the colon in the left pararenal space.

Abstract: Percutaneous puncture of the kidney allows direct access to the pyelocalicial cavities. The posterior approach of this retroperitoneal organ can be complicated of transcolic punctures due to the postrenal position of the colon. A prospective radiological anatomical study of the relationship between the left kidney and the descending colon was undertaken. One hundred computed tomograms of adult subjects were obtained from which the anatomy of the left perirenal area was determined: the descending colon is more frequently behind the kidney in the young females. Two main factors determinants of this situation are: 1) colon ontogenesis in relation to the attachment of the primitive mesocolon, permitting a “fixed” left colon, or “moving” left colon at the end of a long mesocolon, allowing it to pass behind the kidney; 2) a mechanical factor whereby the accumulation of perirenal fat with increasing age may be a limiting factor in lateral displacement of the colon.

Tuberoplasty: Minimally invasive osteosynthesis technique for tibial plateau fractures

Fractures of the tibial plateau are in constant progression. They affect an elderly population suffering from a number of comorbidities, but also a young population increasingly practicing high-risk sports and using two-wheeled vehicles. The objective of this study was therefore to propose a new technique for the treatment of this type of fracture. There are a variety of classical pitfalls of conservative treatment such as defective reduction resulting in early osteoarthritis and alignment defects. Conventional treatments lead to joint stiffness and amyotrophy of the quadriceps, caused by the open technique and late loading. We propose an osteosynthesis technique for tibial plateau fractures with minimally invasive surgery. A minimally invasive technique would be more appropriate to remedy all of the surgical drawbacks resulting from current practices. The surgical technique that we propose uses a balloon allowing progressive and total reduction, associated with percutaneous screw fixation and filling with polymethylmethacrylate (PMMA) cement. The advantages are optimal reduction, minimal devascularization, soft tissues kept intact, as well as early loading and mobilization. This simple technique seems to be a good alternative to conventional treatment. The most comminuted fractures as well as the most posterior compressions can be treated, while causing the least impairment possible. Arthroscopy can be used to verify fracture reduction and cement leakage. At the same time, it can be used to assess the associated meniscal lesions and to repair them if necessary.

Influence of Warm Ischemia Time on Peripheral-Type Benzodiazepine Receptor: A New Aspect of the Role of Mitochondria

The peripheral benzodiazepine receptor (PBR) is located mainly in the outer mitochondrial membrane and many functions are associated directly or indirectly with the PBR. We have studied the influence of different durations of warm ischemia (WI) on renal function, tissue damage and PBR expression in a Large Whitepig model. After a midline incision, the renal pedicle was clamped for 10 (WI10), 30 (WI30), 45 (WI45), 60 (WI60) or 90 min (WI90), and blood and renal tissue samples were collected between 1 day and 2 weeks after reperfusion for assessment of renal function. Metabolite excretion associated with renal ischemia reperfusion injury such as trimethylamine-N-oxide (TMAO) was quantified in blood by magnetic resonance spectroscopy. PBR mRNA and protein expression were determined in renal tissue. TMAO levels rose progressively and significantly with increasing duration of WI. PBR mRNA expression was upregulated between 3 h and 1 day after reperfusion in WI30, WI45 and WI60. Its upregulation was noted 3 days after reperfusion in WI90. At day 14, PBR transcript expression was not different from basal level in any group. PBR protein followed the same pattern. These findings suggest a new role for PBR which could be a major target in the regeneration process during ischemia reperfusion.

Anatomical pitfalls in the technique for total extra peritoneal laparoscopic repair for inguinal hernias

PurposeThe totally extraperitoneal laparoscopic approach for the treatment of inguinal hernia is a well-recognized technique with proven efficacy, low failure rate, and reduced post-operative pain. This laparoscopic technique is reputed to be a more difficult procedure to learn and practice than a laparoscopic trans-abdomino-pre-peritoneal procedure: we hope this is because many surgeons don’t well know extra-peritoneal anatomy of groin. So we proposed a “step by step” anatomical analysis, with pitfalls to avoid, of a totally extraperitoneal laparoscopic approach for treatment of inguinal hernia.MethodsOur experience with totally extraperitoneal laparoscopic inguinal hernia repair with regard to the morphology of the inguinal-femoral region concerns 23 cadaver dissection and more than 400 surgical procedures, now permits clarification of a surgical technique that has hitherto not been well known.ConclusionPhotographic representations of surgical views are displayed, and detailed descriptions applicable to anatomical structures are presented.
