Comparative Assessment of Original vs. Standard Surgery Techniques in Treatment for Purulent Pyelonephritis

Background. Modern minimally invasive surgical techniques reduce traumatism of operative interventions and aggressive anaesthesia, which accordingly shortens the patient’s hospital stay and rehabilitation period.Aim. An improvement of surgical outcomes in patients with purulent pyelonephritis via introduction of laparoscopic techniques.Materials and methods. Th e study included 80 purulent pyelonephritis patients operated at the Territorial Clinical Hospital during 2006—2018. Th e patients were divided between two cohorts. Cohort 1 included 40 (50 %) patients operated with standard techniques (ST), cohort 2 — 40 (50 %) patients having surgery by an original minimally invasive technique (OT). Kidney decapsulation was found to outcome in parenchymal decompression and blood circulation restore in cortical layer. Intraarterial infusion of alprostadil prevents further spread of purulent-destructive processes in kidney.Results and discussion. In patients with the minimally invasive technique, postoperative period proceeded at no complications. On day 1, the patients reported reduced pain syndrome in the surgical area. Contrasted renal MSCT before and aft er surgery showed the recovery of renal blood flow and significant diminishing of destruction foci in short term. Nephrectomy was not performed as no-indication.Conclusion. The treatment outcomes in 40 patients having the new surgical technique demonstrate its efficacy and applicability in clinical practice.

A CONCISE PICTURE OF HERNIA

A hernia is a disease wherein organs or tissues, like the bowel, bulge through the abdominal wall. The etiological, as well as precipitating factors for hernia include abdominal pressure, pre-existing weakness of abdominal muscles, gender, obesity, age, diet, lack of regular exercise, and smoking. Swelling, stiffness, and discomfort seem to be the most prevalent hernia symptoms, particularly while straining, moving, or bending down. Open and laparoscopic techniques are mainly used for hernia repair, both use mesh to counterbalance the abdominal wall flaws and provide a tension-free restoration.

A Consensus Meeting on Expert Recommendations on Operating Specifications for Laparoscopic Radical Resection of Hilar Cholangiocarcinoma

Background: With advances in techniques and technologies, laparoscopic radical resection of hilar cholangiocarcinoma (HCCA) has gradually been carried out in major medical centers in China. Its feasibility and safety have been accepted by a group of Chinese surgical experts.Methods: To standardize perioperative management of HCCA by using laparoscopic resectional approach, to ensure safety of the patient with standardized management, improve prognosis of the patient, and enable proper application and refinement of this surgical approach, the expert group on specifications for laparoscopic radical resection of HCCA in China organized a consensus meeting.Results: Laparoscopic radical resection of HCCA is difficult and associated with high risks. Appropriate patients should be carefully selected and this surgical approach should be promoted gradually. The experts met and arrived at 16 recommendations on perioperative management of HCCA by using laparoscopic surgery. There were three recommendations on preoperative diagnosis and evaluation; one recommendation on surgical principles of treatment; one recommendation on indications and contraindications; one recommendation on credentialing, staffing, and equipment; nine recommendations on laparoscopic techniques in different stages of operation; and one recommendation on indications for conversion to open surgery.Conclusion: Laparoscopic surgery for HCCA is still in the early phase of development. This consensus provides a clinical reference with the aim to promote and to facilitate its further development.

Three-Device (3D) Technique for Liver Parenchyma Dissection in Robotic Liver Surgery

Background: The implementation of robotics in liver surgery offers several advantages compared to conventional open and laparoscopic techniques. One major advantage is the enhanced degree of freedom at the tip of the robotic tools compared to laparoscopic instruments. This enables excellent vessel control during inflow and outflow dissection of the liver. Parenchymal transection remains the most challenging part during robotic liver resection because currently available robotic instruments for parenchymal transection have several limitations and there is no standardized technique as of yet. We established a new strategy and share our experience. Methods: We present a novel technique for the transection of liver parenchyma during robotic surgery, using three devices (3D) simultaneously: monopolar scissors and bipolar Maryland forceps of the robot and laparoscopic-guided waterjet. We collected the perioperative data of twenty-eight patients who underwent this procedure for minor and major liver resections between February 2019 and December 2020 from the Magdeburg Registry of minimally invasive liver surgery (MD-MILS). Results: Twenty-eight patients underwent robotic-assisted 3D parenchyma dissection within the investigation period. Twelve cases of major and sixteen cases of minor hepatectomy for malignant and non-malignant cases were performed. Operative time for major liver resections (≥ 3 liver segments) was 381.7 (SD 80.6) min vs. 252.0 (70.4) min for minor resections (p < 0.01). Intraoperative measured blood loss was 495.8 (SD 508.8) ml for major and 256.3 (170.2) ml for minor liver resections (p = 0.090). The mean postoperative stay was 13.3 (SD 11.1) days for all cases. Liver surgery-related morbidity was 10.7%, no mortalities occurred. We achieved an R0 resection in all malignant cases. Conclusions: The 3D technique for parenchyma dissection in robotic liver surgery is a safe and feasible procedure. This novel method offers an advanced locally controlled preparation of intrahepatic vessels and bile ducts. The combination of precise extrahepatic vessel handling with the 3D technique of parenchyma dissection is a fundamental step forward to the standardization of robotic liver surgery for teaching purposing and the wider adoption of robotic hepatectomy into routine patient care.

P034 STRANGULATED DIAPHRAGMATIC HERNIA: TEN CASES REPORTS

Aim A diaphragmatic hernia (DH) is a protrusion of abdominal contents into the thoracic cavity as a result of a defect within diaphragm. It is most common as a congenital phenomenon; however, there have also been cases where it can be acquired. DH can be life-threatening, resulting in incarceration and strangulation. Material and Methods From June 2009 to April 2021, ten cases of strangulated diaphragmatic hernia were admitted to our Emergency Surgery Department of General Surgery with respiratory and abdominal symptoms. Patients' characteristics, operation details, and postoperative complications were retrospectively analyzed. Results There were 5 (50%) men and 5 (50%) women with a mean age of 66 years (range, 20–85 years). . Emergency surgery was performed by laparoscopic in 4(40%) patients and open in 6(60%) patients. Two patients had a history of penetrating trauma to the left thoracoabdominal region. Segmental bowel resection was performed in 3 patients and total gastrectomy in 1 patient. Reconstruction was not performed in the patient who underwent total gastrectomy due to ischemia and perforation. In the postoperative period, wound infection was observed in 2 patients. Anastomotic leakage was observed in 1 patient and treated with end enterostomy. Empyema was observed in one patient after discharge, the empyema was evacuated and thoracoscopic decortication was performed .The patient who underwent total gastrectomy died due to septic shock and comorbid diseases. Conclusions Strangulated diaphragmatic hernia is a life-threatening condition and requires emergency surgery. Laparoscopic techniques can also be used in treatment.

Laparoscopic resections in the treatment of children with liver tumors: the first experience

Relevance: Surgery is one of the main methods of treating patients with liver neoplasms. At that, minimally invasive surgical techniques facilitate the course of the postoperative period and rehabilitation. The purpose of the study was the selection of optimal surgical treatment for children with liver tumors. Results: In 2014-2020, five patients aged 3-9 years with liver tumors underwent laparoscopic resection at the Morozovskaya Children’s City Clinical Hospital (Moscow, Russia). Out of 3 patients with hepatoblastomas, two patients had stage PRETEXT I, one – stage II. All patients underwent radical surgical treatment (R0); in one child(4%), the resection volume was R1. The duration of operations did not exceed 60 minutes; intraoperative blood loss was within 10 ml/kg; no intraoperative complications were registered. Conclusion: Laparoscopic techniques reduce surgery time and blood loss, prevent intraoperative and postoperative complications, shorten the hospital stay, decrease enteral and drug burden, and the need for chemotherapy. They also facilitate radical surgery and early patient mobilization.

Intraoperative Anesthetic Management in an Asymptomatic and Biochemically Silent Pheochromocytoma

Pheochromocytomas are tumors that originate from the chromaffin tissue of the adrenal medulla and commonly produce catecholamines. The diagnosis is typically established by the measurement of catecholamines or their metabolites in urine or plasma and tumors are localized with the use of radiographic and scintigraphic studies. Pheochromocytomas can occur in asymptomatic patients and the preferred treatment is surgical removal of the tumor. These chromaffin tissue tumors are not uncommon in anesthetic practice and have varied manifestations. The perioperative management of these tumors has improved remarkably over the yearsin conjunction with the evolution of surgical techniques (laparotomy to laparoscopic techniques and now to robotic approaches.). Majority of the patients present with normal clinical and biochemical parameters in the preoperative period, the incidence of hypertension being only 50 %. Even though patients may be clinically asymptomatic, surveillance and proper preoperative evaluation is important, as surgery for associated tumors may precipitate a hypertensive crisis and result in severe complications. We report an intraoperative anesthetic management of 32-year-old female with a left adrenal mass (pheochromocytoma) and left ovarian cyst. Throughout her entire course of treatment she was asymptomatic with normal blood pressure readings. Her biochemical screening was unremarkable. She underwent open surgical resection of the adrenal mass with confirmation of pheochromocytoma on histology. Pheochromocytoma represents very significant challenges to the anesthesiologist’s especially when undiagnosed. This case illustrates how paucity of literature on perioperative preparation of clinically and biochemically silent Pheochromocytomas led to serious intraoperative complications even in an asymptomatic, biochemically negative patient.

The investigation survey of inguinal hernia operation techniques preferred by pediatric surgeons in Turkey

In inguinal hernia, standard procedure has been considered open repair for a long time, the number of pediatric surgeons who prefer laparoscopic techniques is increasing day by day. In this study, it was aimed to determine how pediatric surgeons in our country approach patients with inguinal hernia and manage the treatment process. Controversial issues on inguinal hernia repair were identified and a questionnaire was prepared to reveal the current situation. The questionnaire was delivered to members of Turkish Association of Pediatric Surgery on the official website of the association. The survey was directed to 420 people, 92 people returned with the answers to the questionnaire. Thirty-six of the surgeons prefer the laparoscopic method for inguinal hernia repair. The reason for choosing open surgery was questioned, the most frequent answer was to be more experienced and to have more cumulative knowledge on open repair method. According to survey, the greatest advantage of laparoscopy was stated to be the better evaluation of the contralateral inguinal canal (n=16, %44.4). Twelve of surgeons who performed laparoscopic treatment in the selection of patients stated that gender is important and prefer laparoscopic surgery for female patients. Thirty percent (n = 11) of the participants stated that they prefer laparoscopy in patients between 3 months and 13 years old, while the rest prefer laparoscopy at all ages. In conclusion thirty nine percent of surgeons in Turkey prefer laparoscopic repair. Open repair is still preferred in our country. There is still no consensus on perfect method and patient selection yet.
