Pain is a Limiting Factor in Patients Suitable for Transilluminated Powered Phlebectomy

OBJECTIVES

To analyze, perioperatively and in follow-up, transilluminated powered phlebectomy (TIPP), a surgical technique for the treatment of varicose veins.

METHOD

Retrospective study in one medical institution of patients undergoing TIPP between July 2015 and December 2017. Data analyzed included demographic data, surgery, and results. Postoperatively, pain was evaluated by a 10-point visual analogue scale. The Venous Clinical Severity Score (VCSS) was assessed 5-8 weeks following surgery.

RESULTS

Sixty-six patients with extensive varicosities who underwent TIPP were included. Postoperative pain scores were higher in patients undergoing bilateral compared to unilateral TIPP (visual analogue score 7 versus 5; P=0.031). Following surgery, the VCSS improved in 81.8% (54/66) of the patients. However, 39.7% (25/63; data missing in 3 patients) reported that they would not be willing to undergo a similar procedure in the future. Pain was the most common reason for dissatisfaction.

CONCLUSIONS

Transilluminated powered phlebectomy was associated with considerable pain and discomfort in many patients included in this study. For this reason, it should be reserved for a select group of patients in whom other treatment options are limited; TIPP could be considered in the following cases: patients with a large number of varicosities, reoperations, after extensive thrombophlebitis, obesity, or following bariatric surgery.

[CORRELATION BETWEEN MRI AND ARTHROSCOPIC FINDINGS IN THE DIAGNOSIS OF KNEE PATHOLOGY IN YOUNG AND ADULT PATIENTS]

BACKGROUND

MRI is increasingly used as a diagnostic tool for sports injuries involving the knees before referral to arthroscopy.

OBJECTIVES

Since degenerative changes increase with age, we aimed to evaluate whether age affects the accuracy of MRI.

METHODS

This is a retrospective study of patients with knee injury whose evaluation included both MRI and arthroscopy. Two age groups were defined: young adults (18-39 years) and adults (40 years and above).

RESULTS

Of 966 patients undergoing knee arthroscopy, 132 had preoperative MRI: 48.5% young adults and 51.5% adults. Arthroscopy identified a meniscus tear in 85% and a ligament tear in 21%. Seventeen percent had combined tears and no injury was identified in 4%. The sensitivity and specificity of MRI for ligament tears was 59%, 95%, and for meniscus tears was 91%, and 40%. The sensitivity for bucket handle tears was 86%. The sensitivity of MRI for combined injury was low, 41%. In 8% of patients no pathology was identified by MRI, which was confirmed by arthroscopy in only 4%. One patient with normal MRI had a bucket handle menisceal tear and one other patient had a tear of the anterior cruciate ligament. MRI in adults and young adults revealed that sensitivities for the different types of lesions were similar for both age groups.

CONCLUSIONS

Although degenerative changes increase with age, our hypothesis that MRI will be less sensitive in adults was proven wrong. In the presence of appropriate signs and symptoms, older age should not be considered a factor affecting decisions concerning preoperative imaging workup.

Splenectomy for breast carcinoma diffusely metastatic to the spleen presenting as severe transfusion-dependent anaemia and thrombocytopaenia

We report a 48-year-old woman with metastatic infiltrating lobular carcinoma of the breast. Though her metastatic disease remained stable, she was repeatedly admitted for symptomatic anaemia and treated by red blood cell and platelet transfusions with increasing frequency as time elapsed. Abdominal examination and ultrasound revealed splenomegaly (27 cm span). A bone marrow biopsy showed fibrosis and foci of metastatic carcinoma. Splenectomy ameliorated her transfusion-dependent anaemia and thrombocytopaenia. Histopathology revealed multiple foci of metastatic carcinoma and scattered foci of extramedullary haematopoiesis. Differential diagnosis of anaemia and thrombocytopaenia in patients with cancer include bone morrow involvement by cancer cells, iron-deficiency anaemia, microangiopathies and chemotherapy suppression of haematopoiesis. Splenic involvement with cancer is common in patients with multivisceral disease. Many may regard transfusion-dependent severe anaemia and thrombocytopaenia as an end-stage disease in these patients. Nevertheless, palliative splenectomy should be considered in patients with possible hypersplenism who will otherwise survive for a relatively prolonged period of time.

Hemodynamic consequences of extremity injuries following a terrorist bombing attack: retrospective cohort study

BACKGROUND

Extremities are commonly injured following bomb explosions. The main objective of this study was to evaluate the prevalence of hemorrhagic shock (HS) in victims of explosion suffering from extremity injuries.

METHODS

Retrospective study based on a cohort of patient records maintained in one hospital's mass casualty registry.

RESULTS

Sixty-six victims of explosion who were hospitalized with extremity injuries were identified and evaluated. Sixteen (24.2%) of these were hemodynamically unstable during the first 24 h of treatment. HS could be attributed to associated injuries in seven of the patients. In the other nine patients, extremity injury was the only injury that could explain HS in seven patients and the extremity injury was a major contributor to HS together with another associated injury in two patients. In those 9 patients, in whom the extremity injury was the sole or major contributor to HS, a median of 10 (range 2-22) pRBC was transfused during the first 24 h of treatment. Six of the nine patients were in need of massive transfusion. Fractures in both upper and lower extremities, Gustilo IIIb-c open fractures and AIS 3-4 were found to be risk factors for HS.

CONCLUSIONS

Ample consideration should be given to patients with extremity injuries due to explosions, as these may be immediately life threatening. Tourniquet use should be encouraged in the pre-hospital setting. Before undertaking surgery, emergent HS should be considered in these patients and prevented by appropriate resuscitation.

2017 WSES guidelines on colon and rectal cancer emergencies: obstruction and perforation

ᅟ

Obstruction and perforation due to colorectal cancer represent challenging matters in terms of diagnosis, life-saving strategies, obstruction resolution and oncologic challenge. The aims of the current paper are to update the previous WSES guidelines for the management of large bowel perforation and obstructive left colon carcinoma (OLCC) and to develop new guidelines on obstructive right colon carcinoma (ORCC).

Methods

The literature was extensively queried for focused publication until December 2017. Precise analysis and grading of the literature has been performed by a working group formed by a pool of experts: the statements and literature review were presented, discussed and voted at the Consensus Conference of the 4th Congress of the World Society of Emergency Surgery (WSES) held in Campinas in May 2017.

Results

CT scan is the best imaging technique to evaluate large bowel obstruction and perforation. For OLCC, self-expandable metallic stent (SEMS), when available, offers interesting advantages as compared to emergency surgery; however, the positioning of SEMS for surgically treatable causes carries some long-term oncologic disadvantages, which are still under analysis. In the context of emergency surgery, resection and primary anastomosis (RPA) is preferable to Hartmann’s procedure, whenever the characteristics of the patient and the surgeon are permissive. Right-sided loop colostomy is preferable in rectal cancer, when preoperative therapies are predicted.

With regards to the treatment of ORCC, right colectomy represents the procedure of choice; alternatives, such as internal bypass and loop ileostomy, are of limited value.

Clinical scenarios in the case of perforation might be dramatic, especially in case of free faecal peritonitis. The importance of an appropriate balance between life-saving surgical procedures and respect of oncologic caveats must be stressed. In selected cases, a damage control approach may be required.

Medical treatments including appropriate fluid resuscitation, early antibiotic treatment and management of co-existing medical conditions according to international guidelines must be delivered to all patients at presentation.

Conclusions

The current guidelines offer an extensive overview of available evidence and a qualitative consensus regarding management of large bowel obstruction and perforation due to colorectal cancer.

Planned Re-Laparotomy in a Non-Trauma Setting: A Single Center Experience

BACKGROUND

Damage control laparotomy (DCL) is the widely accepted procedure of choice in management of severely injured trauma patient. It has been implemented in non-trauma-related surgical pathology in the last decade.

OBJECTIVES

To evaluate our experience with planned re-laparotomy (PRL) in non-trauma patients and compare it to other reports.

METHODS

Charts of all patients admitted to Assaf Harofeh Medical Center who underwent PRL for non-trauma-related abdominal pathology during a 6 year period were reviewed. Data regarding demographics, vital signs, laboratory tests, indications for surgery, length of hospital stay, and mortality were obtained from medical charts. Indications for surgery, risk factors, and mortality were analyzed.

RESULTS

The study was comprised of 181 patients. Primary abdominal sepsis (50), postoperative sepsis (49), mesenteric event (32), and intestinal obstruction (28) were the most common indications for PRL. Mortality rate was 48.6%. Factors correlating with increased mortality were advanced age, hypotension, hypothermia, metabolic acidosis, and renal failure. Bowel resection was performed on 122 patients (67%) and primary intestinal anastomosis constructed in 46.7%. Mortality rate was lower in patients who underwent PRL with primary anastomosis compared to patients with postponed bowel anastomosis (33.3% vs. 55.4%, P = 0.018).

CONCLUSIONS

PRL in abdominal emergencies carries a high mortality rate. Primary anastomosis may be considered in non-trauma-related PRL.

Drug Induced Myopia Associated with Treatment for Gynecological Problems

We present three cases of women who developed acute transient myopia caused by drugs for gynecological problems. One patient was treated with disothiazide for premenstrual edema. The second had acute cystitis and was treated by sulphonamide and the third developed myopia coincident with metronidazole treatment for trichomonas vaginalis. We followed these patients by A scan ultrasonographic ocular measurements, documenting reduction of the anterior chamber depth combined with lens thickening. The ocular and myopic changes cleared up completely on discontinuation of the causative agent. The possible mechanism is thought to be an allergic reaction to the drug.

MicroRNA regulation of progesterone receptor in breast cancer

Hormone receptor status is of significant value when deciding on anti-estrogenic adjuvant therapy for breast cancer tumors. However, while estrogen receptor (ER) regulation was intensively studied, the regulation of progesterone receptor (PR) levels has not been extensively investigated. MicroRNAs (miRNAs, miRs) are post-transcriptional negative regulators of gene expression involved in diverse cellular processes. The aim of this study was to identify miRNAs that regulate PR in breast cancer.We mapped potential miRNA binding sites for miR-181a, miR-23a and miR-26b on PR mRNA and demonstrated a direct regulation of PR by these three miRNAs by in-vitro Luciferase binding assays. Over-expression of each miRNA in MCF-7 cells resulted in a reduction in the expression levels of PR mRNA. Then, expression levels of these miRNAs were measured in Formalin-Fixed, Paraffin-Embedded (FFPE) samples of 29 ER-positive breast cancer tumors and adjacent normal breast tissues. A significant reciprocal correlation between PR mRNA and the miRNA levels were identified suggesting a role for miR-181a, miR-23a and miR-26b in PR regulation in breast cancer. Moreover, the average expression fold-changes of the three miRNAs between cancerous and normal tissues displayed an opposite trend when analyzing according to Immuno-histochemistry(IHC) status. Furthermore, miR-181a and miR-26b were found to be over-expressed in most tumor tissues supporting their role in ER-positive breast cancer development. We conclude that miR-181a, miR-23a and miR-26b act as negative regulators of PR expression in ER-positive breast cancer. The diagnostic and prognostic potential of these miRNAs in breast cancer should be further evaluated.

Treatment Options in Gastrointestinal Cutaneous Fistulas

Enterocutaneous fistulas occur most commonly following surgery. A minority of them is caused by a myriad of other etiologies including infection, malignancy, and radiation. While some fistulas may close spontaneously, most patients will eventually need surgery to resolve this pathology. Successful treatment entails adoption of various methods of treatment aimed at control of sepsis, protection of surrounding skin and soft tissue, control of fistula output, and maintenance of nutrition, with eventual spontaneous or surgical closure of the fistula. The aim of this article is to review the various treatment options in their appropriate context.

[PARATHYROID AUTOTRANSPLANTATION IN ADULTS AND CHILDREN]

The indications and methods of parathyroid autotransplantation in children and adults are reviewed, with special emphasis on the methods of immediate transplantation and delayed autotransplantation after cryopreservation. Parathyroid autotransplantation is performed during surgery when all four parathyroid glands have been intentionally resected in parathyroid hyperplasia, or when all four glands were inadvertently damaged during total thyroidectomy, or recurrent neck surgery. When parathyroid damage is suspected during thyroid or extensive neck surgery, cryopreservation of a parathyroid gland is performed. If future signs and symptoms of hypoparathyroidism develop with low blood calcium and PTH levels, then the cryopreserved gland is transplanted into the arm muscles. The maximum effective time that the parathyroid can be cryopreserved is two years. The major postoperative causes of permanent hypoparathyroidism, where parathyroid autotransplantation is indicated are: primary and secondary parathyroid hyperplasia, extensive or repeated neck surgeries which include thyroid surgery and large goiter or retrosternal goiter, particularly in children. The success rate of autotransplantation in preventing postoperative hypoparathyroidism reported in the literature is highly variable, and is dependent on timing, disease, and duration of tissue storage. Although preservation of parathyroid glands in situ at surgery is desirable, parathyroid autotransplantation during thyroidectomy virtually eliminates postoperative hypoparathyroidism. Parathyroid autotransplantation must be performed in dedicated endocrine surgical centers that have had extensive experience in performing this procedure in both children and adults.

Blunt traumatic diaphragmatic injury: A diagnostic enigma with potential surgical pitfalls

BACKGROUND

Blunt traumatic diaphragmatic injury (BTDI) is an uncommon injury and one which is difficult to diagnose. The objective of this study was to identify features associated with this injury.

METHODS

This was a retrospective study based on records of 354307 blunt trauma victims treated between 1998 and 2013 collected by the Israeli National Trauma Registry.

RESULTS

BTDI was reported in 231 (0.065%) patients. Motor vehicle accidents were responsible for 84.4% of the injuries: 97 (42.0%) were reported as drivers; 54 (23.4%) were passengers; 34 (14.7%) were pedestrians hit by cars; and 10 (4.3%) were on motorcycles. There were more males than females (2.5:1) compared with blunt trauma patients without BTDI (p<.001). Patients with BTDI were significantly younger than blunt trauma patients without BTDI (p<.001). ISS was 9-14 in 5.2%, 16-24 in 16.9%, 25-75 in 77.9%. Urgent surgery was performed in 62% of the patients and 79.7% had surgery within 24h of admission. Mortality was 26.8%. Over 40% of patients with BTDI had associated rib, pelvic and/or extremity injuries. Over 30% had associated spleen, liver and/or lung injuries. Nevertheless, less than 1% of patients with skeletal injuries and less than 2.5% with solid organ injuries overall had associated BTDI. Despite hollow viscus injury being less prevalent, up to 6% of patients with this injury had associated BTDI.

CONCLUSIONS

BTDI is infrequent following blunt trauma. Hollow viscus injuries were more predictive of BTDI than skeletal or solid organ injuries.

Glasgow Coma Scale Score in Survivors of Explosion With Possible Traumatic Brain Injury in Need of Neurosurgical Intervention

IMPORTANCE

Head injury following explosions is common. Rapid identification of patients with severe traumatic brain injury (TBI) in need of neurosurgical intervention is complicated in a situation where multiple casualties are admitted following an explosion.

OBJECTIVE

To evaluate whether Glasgow Coma Scale (GCS) score or the Simplified Motor Score at presentation would identify patients with severe TBI in need of neurosurgical intervention.

DESIGN, SETTING, AND PARTICIPANTS

Analysis of clinical data recorded in the Israel National Trauma Registry of 1081 patients treated following terrorist bombings in the civilian setting between 1998 and 2005. Primary analysis of the data was conducted in 2009, and analysis was completed in 2015.

MAIN OUTCOMES AND MEASURES

Proportion of patients with TBI in need of neurosurgical intervention per GCS score or Simplified Motor Score.

RESULTS

Of 1081 patients (median age, 29 years [range, 0-90 years]; 38.9% women), 198 (18.3%) were diagnosed as having TBI (48 mild and 150 severe). Severe TBI was diagnosed in 48 of 877 patients (5%) with a GCS score of 15 and in 99 of 171 patients (58%) with GCS scores of 3 to 14 (P < .001). In 65 patients with abnormal GCS (38%), no head injury was recorded. Nine of 877 patients (1%) with a GCS score of 15 were in need of a neurosurgical operation, and fewer than 51 of the 171 patients (30%) with GCS scores of 3 to 14 had a neurosurgical operation (P < .001). No difference was found between the proportion of patients in need of neurosurgery with GCS scores of 3 to 8 and those with GCS scores of 9 to 14 (30% vs 27%; P = .83). When the Simplified Motor Score and GCS were compared with respect to their ability to identify patients in need of neurosurgical interventions, no difference was found between the 2 scores.

CONCLUSIONS AND RELEVANCE

Following an explosion in the civilian setting, 65 patients (38%) with GCS scores of 3 to 14 did not experience severe TBI. The proportion of patients with severe TBI and severe TBI in need of a neurosurgical intervention were similar in patients presenting with GCS scores of 3 to 8 and GCS scores of 9 to 14. In this study, GCS and Simplified Motor Score did not help identify patients with severe TBI in need of a neurosurgical intervention.

Concomitant hollow viscus injuries in patients with blunt hepatic and splenic injuries: an analysis of a National Trauma Registry database

INTRODUCTION

Non-operative management has become the standard approach for treating stable patients sustaining blunt hepatic or splenic injuries in the absence of other indications for laparotomy. The liberal use of computed tomography (CT) has reduced the rate of unnecessary immediate laparotomies; however, due to its limited sensitivity in the diagnosis of hollow viscus injuries (HVI), this may be at the expense of a rise in the incidence of missed HVI. The aim of this study was to assess the incidence of concomitant HVI in blunt trauma patients diagnosed with hepatic and/or splenic injuries, and to evaluate whether a correlation exists between this incidence and the severity of hepatic or splenic injuries.

METHODS

A retrospective cohort study involving blunt trauma patients with splenic and/or liver injuries, between the years 1998 and 2012 registered in the Israel National Trauma Registry. The association between the presence and severity of splenic and/or liver injuries and the incidence of HVI was examined.

RESULTS

Of the 57,130 trauma victims identified as suffering from blunt torso injuries, 2335 (4%) sustained hepatic injuries without splenic injuries (H group), 3127 (5.4%) had splenic injuries without hepatic injuries (S group), and 564 (1%) suffered from both hepatic and splenic injuries (H+S group). Overall, 957 patients sustained 1063 HVI. The incidence of HVI among blunt torso trauma victims who sustained neither splenic nor hepatic injuries was 1.5% which is significantly lower than in the S (3.1%), H (3.1%), and H+S (6.7%) groups. In the S group, there was a clear correlation between the severity of the splenic injury and the incidence of HVI. This correlation was not found in the H group.

CONCLUSIONS

The presence of blunt splenic and/or hepatic injuries predicts a higher incidence of HVI, especially if combined. While in blunt splenic injury patients there is a clear correlation between the incidence of HVI and the severity of splenic injury, such a correlation does not exist in patients with blunt hepatic injury.

Pitfalls to avoid in the medical management of mass casualty incidents following terrorist bombings: the hospital perspective

BACKGROUND

The unique patterns of injury following explosions together with the involvement of numerous physicians, most of whom are not experienced in trauma, may create problems in the medical management of mass casualty incidents.

METHODS

Four hundred patient files admitted in 19 mass casualty events following bombing incidents were reviewed and possible areas which could impact survival were defined.

RESULTS

Forty-nine (9.3 %) patients had an Injury Severity Score ≥16. Of 205 patients in whom triage decisions were available, 5 of 25 severely injured patients were undertriaged by the triage officers at the door of the hospital. Following primary evaluation inside the emergency department critical injuries in two patients were missed due to distracting, less serious injuries. Of 68 (16.1 %) patients who were operated, 28 were in need of either immediate, urgent or high-priority operations. Except for neurosurgical cases which needed to be transferred to other hospitals, there was no delay in surgery. One patient underwent negative laparotomy. There were 15 in-hospital deaths, 6 of which were deemed as either anticipated or unanticipated mortality with possibility for improvement.

CONCLUSION

Medical management should be evaluated following MCIs as this may illustrate possible problems which many need to be addressed in contingency planning.

Abdominal blast injuries: different patterns, severity, management, and prognosis according to the main mechanism of injury

PURPOSE

To review the frequency, different patterns, anatomic severity, management, and prognosis of abdominal injuries in survivors of explosions, according to the main mechanism of injury.

METHODS

A MEDLINE search was conducted from January 1982 to August 2013, including the following MeSH terms: blast injuries, abdominal injuries. EMBASE was also searched, with the same entries. Abdominal blast injuries (ABIs) have been defined as injuries resulting not only from the effects of the overpressure on abdominal organs, but also from the multimechanistic effects and projectile fragments resulting from the blast. Special emphasis was placed on the detailed assessment of ABIs in patients admitted to GMUGH (Gregorio Marañón University General Hospital) after the Madrid 2004 terrorist bombings, and in patients admitted to HYMC (Hillel Yaffe Medical Centre) in Hadera (Israel) following several bombing episodes. The anatomic severity of injuries was assessed by the abdominal component of the AIS, and the overall anatomic severity of casualties was assessed by means of the NISS.

RESULTS

Abdominal injuries are not common in survivors of terrorist explosions, although they are a frequent finding in those immediately killed. Primary and tertiary blast injuries have predominated in survivors from explosions in enclosed spaces reported outside of Israel. In contrast, secondary blast injuries causing fragmentation wounds were predominant in suicide bombings in open and/or semi-confined spaces, mainly in Israel, and also in military conflicts. Multiple perforations of the ileum seem to be the most common primary blast injury to the bowel, but delayed bowel perforations are rare. Secondary blast injuries carry the highest anatomic severity and mortality rate. Most of the deaths assessed occurred early, with hemorrhagic shock from penetrating fragments as the main contributing factor. The negative laparotomy rate has been very variable, with higher rates reported, in general, from civilian hospitals attending a large number of casualties.

CONCLUSIONS

The pattern, severity, management, and prognosis of ABI vary considerably, in accordance with the main mechanism of injury.
