The Impact

SummaryDuring the preclinical period of medical school, the clinical relevance of theoretical knowledge is given little attention. Medical students of the second year were invited to participate in an interdisciplinary congress for robot-assisted and digital surgery. The students had to evaluate the impact of the congress on their learning motivation, decision-making for a career in surgery, and relevance for their educational curriculum. Participation in the congress increased their learning motivation for preclinical subjects, and significantly increased their interest in a surgical career. Most students considered active involvement in medical congresses a valuable supplement to the medical curriculum. Congress participation during the preclinical period was ranked positively by medical students. Greater learning motivation and enthusiasm for the pilot teaching project as well as for surgical disciplines were registered. Thus, early involvement of medical students in scientific congresses should be an integral part of their educational curriculum.

Diagnosis Of Diseases

The article presents the results of video laparoscopy (VLS) performed in 2008–2019 in 5,599 patients in order to diagnose acute diseases of the abdominal organs requiring emergency surgery, identify competing and concomitant diseases, and determine treatment tactics. 2,442 (43.6 %) of them made up group I, with no doubt; 2,656 (47.4 %) – II group, with presumptive reliability; and 501 (9.0 %) – group III, with an unclear clinical diagnosis of the disease. In 2,326 (95.2 %) patients of group I with VLS, the clinical diagnosis was confirmed, in 100 (4.1 %) other diseases were revealed, and in 16 (0.7 %) the diagnosis was not established. Competing diseases were found in 8 patients and concomitant diseases in 4. In 1,641 (61.8 %) patients of group II, VLS made it possible to clarify and differentiate the clinical diagnosis of diseases, in 929 (35.0 %) – to identify other diseases, and in 86 (3.2 %) the diagnosis was not possible. When performing differential diagnosis, 126 other diseases were identified more than the number of patients. Competing diseases were found in 6 patients and concomitant diseases in 6 patients. 356 (71.0 %) patients of group III with VLS were diagnosed with major diseases, 75 (15.0 %) had other diseases, and 70 (14.0 %) were not diagnosed. In 4 patients, competing diseases were found, and in 1 – concomitant disease. Of the 5,427 (96.9 %) patients with the definitive diagnosis of the disease established with VLS, 3,828 (70.5 %) were found to be able to perform VLS operations, in 10 (0.3 %) of them – simultaneous with competing diseases.

Histopathological Lesion

A 16-year-old female who was attended as an outpatient reported localized, acute abdominal pain with vomiting, symmetrical motor weakness, and burning sensation in both arms and legs. Her medical history showed irrational behavior, repeated admissions at the emergency units of many other reference hospitals, where she had been investigated for celiac disease and treated with analgesics for pain events. Her clinical condition remained unchanged despite the use of many oral analgesics. In those admissions, she showed dysautonomia, vomiting, and abdominal pain. Diagnosis investigation disclosed a notable serum hyponatremia (133.7 mEq/L). She was referred for endoscopy and the histopathological lesion of the antrum in the stomach did not show neoplastic lesions. Colonoscopy, pelvic magnetic resonance imaging (MRI), total abdominal computed tomography, and video laparoscopy were without significant abnormalities. Suspicion of acute intermittent porphyria was confirmed by quantitative urine porphobilinogen-level tests and genetic analysis. Patient was successfully treated with intravenous infusion of glucose and hemin therapy.

Kidney Metastasis

A 47-year-old woman was admitted to our clinic for intensive pain in the left flank region. The transvaginal ultrasound showed a left adnexal solid mass with ascites. She had undergone surgical removal of skin melanoma in 2008, but in September 2019, intracardiac metastasis resulting from it had been discovered. CT performed in March 2020 had been negative for other metastases. A full abdomen ultrasound was not performed. During the night, the patient began to show signs and symptoms of hypovolaemic shock. The patient was urgently transferred to the operating room for a video laparoscopy. A vast left retroperitoneal haematoma was diagnosed along with voluminous enlargement of the left ovary. We proceeded with a left adnexectomy and blood transfusion. Subsequent contrast-enhanced CT revealed a left subcapsular, perirenal haematoma and a voluminous retroperitoneal haematoma. Kidney metastasis was also seen. The final histological diagnosis was metastatic amelanotic malignant melanoma of the ovary.

The Impact

Introduction:In 2016, a health technology assessment (HTA) was conducted to gather evidence on the safety and overall effectiveness of performing laparoscopic surgery by using 3D videolaparoscopy (3DVL) versus 2D videolaparoscopy (2DVL) display systems in a variety of pediatric surgical procedures in order to efficiently support the final investment decision on video system to be acquired. Results showed that 3DVL might be a good alternative to 2DVL. Moreover, sensitivity analysis has also confirmed that the results associated to the best technology (3DVL) are robust; this has led to a confident decision for recommending it in Bambino Gesù Children's Hospital (OPBG). The objective of this work is to evaluate the impact of 3DVL within the hospital setting after 12 months its introduction in clinical practice.Methods:After 12 months since the technology's introduction, clinical data, identified in previous HTA study, were extracted from surgery registries; data concerning the number of surgeries, duration of intervention, blood loss and surgery complications were analyzed. Statistical analyses on these data, between pre and post 3D system implementation period were carried out.Results:Results confirmed the 2016 HTA results, highlighting clinical advantages identified a priori. The percentage of the number of laparoscopic procedures significantly increased from 12 percent in pre-3D system installation period to the 20 percent in post 3D system installation (p=7,35E-6). No statistical differences in length of hospital stay, operative time, incidence of perioperative blood loss and surgery complication, between pre- and post- 3D installation period were identified.Conclusions:This study highlighted the importance of a HTA process before the acquisition of a technology for which the investment decision is not obvious, because benefits and drawbacks of the new technology are unclear. Preliminary results showed that 3D video laparoscopy system seems to be better than the 2D laparoscopy system. However, more data has to be examined to be able to establish the final judgement.

Toe Deformity

Digital surgery is one of the most common types of surgery performed by foot and ankle surgeons. Flail toe is a complication that may occur after overaggressive resection arthroplasty of the proximal interphalangeal joint of the lesser toes. Correction of flail toe deformity has received little attention and has predominantly involved soft-tissue procedures. The authors’ preferred technique for the surgical correction of flail toe is to place a unicortical autogenous bone graft (harvested from the ipsilateral calcaneus) within the revised proximal interphalangeal joint of the lesser toes to create a distraction arthrodesis. This technique allows restoration of digital length, stability, and purchase. A retrospective review of 22 such procedures in 13 patients is presented, along with a literature review of other procedures and a description of the authors’ current surgical technique and postoperative management protocol. Overall success using the authors’ procedure was 82%. Complications occurred in three patients, with one of the grafts showing complete resorption and two requiring additional surgical intervention owing to nonunion and malunion of toes.

Reproductive Events

Previous techniques of recording myometrial activity in vivo gave limited information about the nature of contractions, and disrupted normal reproductive events. To overcome these drawbacks we developed a new in vivo method of video laparoscopy (VL). This involves positioning a laparoscope in the abdomen of anaesthetized rats to view the caudal ends of both uterine horns. Myometrial activity is recorded by video camera onto video tape. Myometrial contractions are classified according to the muscle layers involved, the interaction between layers and the direction of propagation. Experiments with intrauterine balloons and electromyography (EMG) in conscious and ketamine/xylazine anaesthetized rats showed that this anaesthetic does not have major effects on myometrial activity. To validate the VL method, recordings were obtained throughout the oestrous cycle and compared with results obtained with EMG in conscious rats. The frequency and pattern of activity were similar with both techniques although more information was obtained from VL. Frequency of contractions was highest in oestrus and dioestrus and lowest in pro-oestrus, when contractions occurred in groups separated by quiescent intervals. At all stages, longitudinal contractions propagating towards the cervix predominated. Circular muscle activity was only seen at oestrus and dioestrus; that at oestrus consisted of weak peristalses, that at dioestrus was more complex. A major advantage of VL is that it does not interfere with the course of the oestrous cycle, pseudopregnancy or early pregnancy.
