Preoperative Hyponatremia Indicates Complicated Acute Appendicitis.

Introduction: Acute appendicitis is the most common surgical emergency. Early detection of patients with complicated appendicitis leads to prompt surgical management and better outcome. This study investigated the relationship between the severity of acute appendicitis and the presence of preoperative hyponatremia. Materials and Methods: We retrospectively reviewed the medical files of adult patients operated on for acute appendicitis over a 6-year period. Hyponatremia was defined as serum sodium level of ≤135 mEq/L. Patients were classified into complicated appendicitis and noncomplicated appendicitis according to operative findings and/or histopathology reports. Results: A total of 129 patients were identified and included in this study. Complicated appendicitis was found more frequently in female patients and older patients. Hyponatremia was found significantly more frequently in patients with complicated appendicitis (p < 0.001) and also in patients with perforation than without perforation (p=0.047). Conclusions: The present study demonstrated that preoperative hyponatremia is associated with complicated appendicitis. Serum sodium levels, a routine, low-cost laboratory test, could act as an accessory marker aiding surgeons in earlier identification of gangrenous or perforated acute appendicitis.

The Impact of COVID-19 on the Training of Surgical Residents in Greece: Results of a Survey Conducted One Year after the Onset of the Pandemic.

Background: The coronavirus disease (COVID-19) pandemic is an ongoing crisis. In light of mounting concerns about the training of surgical residents, we examined surgical residents perceptions regarding the pandemic's impact on their training. Methods: We developed an anonymous online questionnaire comprising 15 multiple-choice questions, which we sent via email to residents educated and employed in northern Greece hospitals. Our survey took place in January and February of 2021. Results: A total of 124 residents across a broad spectrum of surgical fields completed the questionnaire. The majority (51.6%) reported a significant decline in the number of operations performed weekly during the pandemic. Approximately 38% of the respondents stated that their surgical skills have been negatively affected to a significant extent, and 35.5% reported that their theoretical knowledge had deteriorated to a moderate extent. Almost half of them reported that they were satisfied with the online courses and a total of 67.7% affirmed the need to prolong their clinical training. Conclusions: The aims and scope of a surgical department include the provision of high-quality training to young surgeons. The impact of the pandemic on routine surgical activities has been dramatic. Our results clearly indicate that young surgeons have been significantly affected in terms of their training.

Non-Operative Management of Delayed Splenic Rupture 4 Months Following Blunt Abdominal Trauma.

BACKGROUND Delayed splenic rupture is a rare complication of non-operative management of a primary splenic trauma which, without proper clinical vigilance, may result in life-threatening events. It usually occurs 4-8 days after injury and, in most cases, surgery is the treatment of choice. Since non-operative management of splenic trauma, which allows splenic salvage, has become increasingly popular, the same approach could also be applied in delayed splenic rupture. We herein present a case of delayed splenic rupture that occurred 4 months after the trauma and was successfully managed non-operatively. CASE REPORT A 32-year-old woman presented with diffuse abdominal pain, chest pain, and dyspnea 4 months after sustaining minor thoracoabdominal blunt trauma due to a car accident. That event was inadequately investigated and was not admitted for further monitoring. Computerized tomography revealed a rupture of a splenic hematoma in the context of the previous splenic trauma. She was closely monitored and remained hemodynamically stable. She was discharged and followed up, with no reported relapse of her clinical condition. CONCLUSIONS Delayed splenic rupture occurring 4 months after the primary splenic trauma is extremely rare. Due to its prolonged delay, delayed rupture of the spleen can easily be overlooked and not be included in the original differential diagnosis. Negligence of this event can result in dreaded complications with hemodynamic instability or even death. Furthermore, its higher mortality rate compared to primary splenic rupture highlights the importance of proper clinical vigilance. Non-operative management should be attempted in hemodynamically stable patients.

Robot-Assisted Thyroidectomy Versus Open Thyroidectomy in the Treatment of Well Differentiated Thyroid Carcinoma.

BACKGROUND: The incidence of thyroid cancer has increased worldwide during the last decade, becoming the most common endocrine malignancy and accounting for 3.8% of new cancer diagnosis. Surgical resection, namely conventional thyroidectomy, remains at the frontline of therapy, as surgical outcomes are undoubtedly successful. Minimally invasive techniques gained popularity through the years, in terms of feasibility, safety, and cosmesis. However, endoscopic approach could be characterized by some limitations concerning thyroid surgery. Robotic technology with its unique features was introduced to overcome these limitations. Since then, robotic thyroidectomy has been used for both benign and malignant thyroid disease. DATABASE: This study presents the use of robot-assisted transaxillary thyroidectomy in well-differentiated thyroid carcinoma through an extensive review of the literature in the PubMed database, including previous meta-analyses and case series. CONCLUSION: In terms of oncological efficacy, morbidity, and quality of life, outcomes seem comparable in thyroid cancer patients undergoing either open or robotic thyroidectomy. Surgical completeness also appears similar. Moreover, the rates of locoregional recurrence and survival outcome at 5 years are similar between the former and the latter, thus confirming the oncological value of robotic thyroidectomy for differentiated thyroid cancer. In order for more surgeons to adopt robotic approaches several issues need to be resolved, namely: expansion of robotic thyroidectomy in treating larger well-differentiated carcinomas and neck dissection, equipment costs, and prolonged operation times.

Undiagnosed Endoscopy Capsule Retention Causing Delayed Intestinal Obstruction in a Patient with a Small Bowel Neuroendocrine Tumor.

BACKGROUND Capsule endoscopy has played a significant role in small bowel investigation, providing the opportunity of detecting neoplastic lesions to a greater degree and at an earlier stage than other diagnostic procedures. Failure to excrete the capsule with the feces within 48 h can lead to capsule retention with increased risk of further complications such as bowel obstruction and perforation. Capsule retention can remain undetected in case of incomplete follow-up and poor patient compliance. Acute small bowel obstruction as late as many months following capsule endoscopy investigation is very rare, with only a few cases reported in the published literature. We herein report a rare case of prolonged capsule retention which remained undiagnosed, resulting in small bowel obstruction 6 months after the initial investigation. CASE REPORT An 82-year-old woman presented with abdominal pain and symptoms suggestive of intestinal obstruction. The patient history included a capsule endoscopy investigation because of episodes of abdominal pain 6 months prior to admission. Both the outcome of the investigation and the excretion of the capsule remained undetermined due to her history of dementia and follow-up failure. Radiologic investigations identified the capsule causing small bowel obstruction. Upon surgery, the capsule was found to be impacted in a stenotic small bowel lesion, and a segmental small bowel resection was performed. Histologic examination revealed the presence of a stenotic small bowel neuroendocrine tumor. CONCLUSIONS Appropriate follow-up is necessary to diagnose the complication of capsule retention which, if it remains unrecognized, can cause life-threatening complications as late as many months after capsule endoscopy.

A case of acute abdomen caused by spontaneous rupture of a splenic abscess secondary to cancer of the splenic flexure.

Splenic abscesses are rare, difficult to diagnose, difficult to treat and usually appear in immunosuppressed patients. We present the case of a 64-year-old patient with left pleuritic chest pain, anorexia and fever with rigors diagnosed with splenic abscess due to splenic flexure colon cancer. The abscess spontaneously ruptured and the patient was operated on for acute abdomen. Splenectomy and Hartmann's hemicolectomy were performed. The patient was discharged from the hospital and referred to the oncologic department. Continuous spread of infection and especially initiating from a cancer lesion is a usual mechanism of splenic abscess formation. Although computed tomography-guided percutaneous drainage is the treatment of choice, an exploratory laparotomy was necessary in this case because of the rupture of the abscess. It is important for the clinicians to include splenic abscesses and their complications in the differential diagnosis of acute abdomen.

B-Lymphoblastic Lymphoma of the Small Bowel: An Extremely Rare Occurrence.

B-lymphoblastic lymphoma is a neoplasm of immature B cells and is characterized by aggressive behavior and disease progression. Common sites of involvement are skin, lymph nodes, bone, soft tissues, breast, and the mediastinum. Gastrointestinal lesions are rarely encountered and therefore not fully described. We herein report the case of a 28-year-old male, who presented with abdominal pain and CT scan showed a tumor involving the small bowel and its mesentery. He underwent emergency laparotomy and enterectomy. Histopathology report revealed B-lymphoblastic lymphoma affecting the small bowel and the adjacent mesentery. This is the first documented case of a small bowel tumor diagnosed as B-lymphoblastic lymphoma in published literature.
