Preventive esophagomyobronchoplasty as a method to prevent the failure of the bronchial stump in pneumonectomy for lung cancer

Aim. Comparative analysis of insufficiency rate of bronchial stump sutures in pneumonectomy for lung cancer, depending on suturing techniques. Methods. A patented technique for bronchial stump suturing has been introduced into the practice of the GOBUZ clinic Novgorod Regional Clinical Hospital based on the Department of thoracic surgery since 2015 for pneumonectomy for lung cancer. Before the introduction of the developed technique, various generally accepted methods of bronchial stump forming were used (mechanical suture, manual suture, their combination, bronchial stump coverage with mediastinal pleura, pericardial flap). A retrospective analysis of 173 case histories and operational protocols of patients with lung cancer who underwent pneumonectomy was carried out for the failure of bronchial stump sutures when using conventional suturing techniques between 2010 and 2014 (the first group of patients). We also performed a retrospective and prospective analysis of 204 case histories and operational protocols of patients in a similar clinical group when using a patented suturing technique between 2015 and 2020 (the second group of patients). Statistical analysis was carried out by using Statistica 10.0 software (StatSoft, Inc. 2011). The qualitative and quantitative indicators were analyzed by using the Pearsons 2-test with Yatess correction. Results. A retrospective analysis shows that the failure rate in the use of generally accepted bronchial stump suturing techniques for 20102014 was 10.4%. After the implementation of the method of preventive esophagobronchomyoplasty, complications as bronchial stump suture failure were not detected in any case between 2015 and 2020. Conclusion. The study shows high efficiency, a decrease in the incidence of complications as the failure of bronchial stump sutures in the use of the developed method of preventive esophagomyobronchoplasty in pneumonectomy for lung cancer.

Experience in the Treatment of Late Mechanical Suture Failure after Longitudinal Laparoscopic Sleeve Gastrectomy Using Minimally Invasive Techniques

последнее десятилетие лапароскопическая продольная резекция желудка заняла ведущую позицию среди бариатрических операций. К наиболее тяжелым осложнениям послеоперационного периода относят несостоятельность механического шва культи желудка. Целью данного сообщения служит демонстрация случая успешного лечения поздней несостоятельности механического шва после лапароскопической продольной резекции желудка с использованием мини-инвазивных методик. Пациентке, 56 лет, с индексом массы тела 50, выполнена лапароскопическая продольная резекция желудка с использованием калибровочного зонда 36 Fr. Проверка на герметичность линии механического шва проведена введением 150 мл жидкости, окрашенной метиленовым синим. Несостоятельность механического шва была диагностирована на 12 сутки после операции с помощью компьютерной томографии. При рентгенологическом исследовании желудка, проведенном дважды, обнаружить затеков контрастного вещества не удалось. С целью закрытия зоны несостоятельности культи желудка эндоскопическим путем был установлен полностью покрытый саморасширяющийся стент, а зона абсцесса была дренирована при релапароскопии. При дислокации стента ниже кардиального жома проведена его переустановка. Через 4 недели свищ перестал функционировать,

Pharyngeal closure after a total laryngectomy: mechanical versus manual technique

ObjectiveTo verify the main advantages and drawbacks of mechanical suturing for pharyngeal closure after total laryngectomy versus a manual suturing technique.MethodsA retrospective review was carried out of 126 total laryngectomies performed between 2008 and 2018. Manual closure was performed in 80 cases (63.5 per cent) and mechanical suturing was performed in 46 cases (36.5 per cent).ResultsMechanical suturing was used significantly more frequently in patients with: glottic tumours (p = 0.008), less local tumour extension (p = 0.017) and less pre-operative morbidity (p = 0.014). There were no significant differences in the incidence of pharyngocutaneous fistula between the manual suture group (16.3 per cent) and the mechanical suture group (13.0 per cent) (p = 0.628). None of the patients treated with mechanical suturing had positive surgical margins. Cancer-specific survival for the mechanical suture group was higher than that for the manual suture group (p = 0.009).ConclusionMechanical suturing of the pharynx after total laryngectomy is an oncologically safe technique if used in suitable cases.

Hemorragia digestiva alta y divertículo duodenal. Reporte de un caso

Bleeding duodenal diverticulum is an infrequent pathology in need of emergency treatment due to its high mortality. We present the clinical case of a 72-year-old patient with multiple comorbidities, who was admitted with upper gastrointestinal bleeding, abdominal pain and hemodynamic instability. Once hemodynamic stability was achieved, upper digestive endoscopy was performed, showing duodenal diverticulum in the upper knee with bleeding in the fundus, performing hemostatic control. CT was requested: at the level of the upper duodenal knee, wide base diverticulum. Surgery was scheduled for the high risk of new bleeding. In surgery, cholecystectomy and diverticulectomy were performed laparoscopically with mechanical suture. Anatomopathological report: duodenal wall with parietal thinning of the duodenum, suggestive of diverticulum by pulsion. The discharge was granted with radiological control on the 3rd postoperative day. The aim of this case is to show the importance of endoscopic resolution of urgency and subsequent laparoscopic management in a patient with important risk factors, evidencing the short hospital stay without postoperative complications.

New way of laparascopic intracorporeal term-terminal invagination ileotransverse anastomosis

Background. Laparoscopic surgery becomes a standard treatment for many surgical diseases. Defects of a stapler laparoscopic mechanical suture during the formation of an anastomosis after hemicolectomy are detected in 18% of observed cases.Objective. Development, substantiate reproducibility and safety of a manual intracorporeal term-terminal invagination ileotransverse anastomosis method after performing the right laparoscopic hemicolectomy.Material and Methods. Authors presented a description of the technique and their own experience of performing laparoscopic hemicolectomy on the right with the formation of a manual original anastomosis in 10 patients with pathology of the right half of the colon. Eight patients (80.0%) had a malignant tumor of the right half of the colon, 1 patient (10.0%) showed multiple polyps of the cecum and the ascending part of the colon, 1 patient (10.0%) developed a cystic-solid submucosa tumor of the ileocecal angle. One patient had metastatic lung disease at the time of establishing diagnosis. The postoperative follow-up period was 7-18 months.Result. There were no conversions to open surgery. All operations (n = 10) were ended completely laparoscopically - right hemicolectomy with standard D2 lymph node dissection. In one patient, we revealed intraoperatively the spread of the tumor to the gallbladder, which required additional cholecystectomy. The duration of the operation was 122.5±10.7 min.; median blood loss was 107±5.2 ml. At the time of follow-up all patients are alive.Conclusion. The technique is universal in the surgical treatment of patients with various pathologies of the right half of the colon.

Suture-Tool: A Mechanical Needle Driver for Standardized Wound Closure

Introduction A laparotomy is commonly required to gain abdominal access. A safe standardized access and closure technique is warranted to minimize abdominal wall complications like wound infections, burst abdomen and incisional hernias. Stitches are recommended to be small and placed tightly, obtaining a suture length-to-incision length (SL/WL) ratio of ≥ 4:1. This can be time-consuming and difficult to achieve especially following long trying surgical procedures. The aim was to develop and evaluate a new mechanical suture device for standardized wound closure. Methods A mechanical suture device (Suture-tool) was developed in collaboration between a medical technology engineer team with the aim to achieve a standardized suture line of high quality that could be performed speedy and safe. Ten surgeons closed an incision in an animal tissue model after a standardized introduction of the instrument comparing the device to conventional needle driver suturing (NDS) using the 4:1 technique. Outcome measures were SL/WL ratio, number of stitches and suture time. Results In total, 80 suture lines were evaluated. SL/WL ratio of ≥ 4 was achieved in 95% using the Suture-tool and 30% using NDS (p < 0,001). Number of stitches was similar. Suture time was 30% shorter using the Suture-tool compared to NDS (2 min 54 s vs. 4 min 5 s; p < 0.001). Conclusions The mechanical needle driver seems to be a promising device to perform a speedy standardized high-quality suture line for fascial closure.

Stapling technology with triple-row and enhanced staple configurations evaluated in a series of 124 consecutive laparoscopic vertical gastrectomies

Background: Laparoscopic sleeve gastrectomy (LSG) is a procedure frequently used to treat morbid obesity, due to its simplicity compared to other bariatric techniques. However, LSG can lead to serious complications, such as gastric leakage and bleeding from the staple line. To reduce these complications, seroserosal reinforcement of the mechanical suture line after gastrectomy is generally recommended. In recent decades, studies have focused on the safety of anastomosis with staples, especially compared to manual sewing techniques. Since studies on the improvement of stapling technology are limited, this study arises to compare the clinical results of staple line oversewing versus stapling technology with triple-row and enhanced staple configurations in laparoscopic sleeve gastrectomy.Methods: A retrospective review from a prospectively maintained database of 124 laparoscopic vertical gastrectomies performed at single centre between March 2010 and December 2016. Patients were divided into two groups, with comparable anthropometric parameters and inclusion criteria. Seroserosal reinforcement was used in the first group, and stapling technology with triple-row and enhanced staple configurations in the second. Rates of anastomotic leakage, bleeding, reoperation, and 30-day mortality were compared.Results: In Group 1 the average surgical time was 125 min, whereas in Group 2 it was 87 min. No differences were found between the two groups regarding leakage or bleeding of the staple line.Conclusions: The use of triple-row stapling devices during laparoscopic vertical gastrectomy enables surgical time to be reduced. Further high-quality studies to evaluate the efficacy and effectiveness of stapling technology with triple-row and enhanced staple configurations are needed.

COMPARATIVE ANALYSIS OF LATE RESULTS OF CERVICAL ESOPHAGOGASTRIC ANASTOMOSIS BY MANUAL AND MECHANICAL SUTURE IN PATIENTS SUBMITTED TO ESOPHAGEAL MUCOSECTOMY THROUGH ADVANCED MEGAESOPHAGUS

ABSTRACT Background: Among the anastomoses of the gastrointestinal tract, those of the esophagus are of special interest due to several anatomical or even general peculiarities. Aim: Evaluate retrospectively the results comparing mechanical vs. manual suture at cervical esophagogastric anastomosis in megaesophagus treatment. Methods: Were included 92 patients diagnosed with advanced megaesophagus with clinical conditions to undergo the surgery. All underwent esophageal mucosectomy, performing anastomosis of the esophagus stump with the gastric tube at the cervical level. In order to make this anastomosis, the patients were divided into two groups: group A (n=53) with circular mechanical suture, lateral end; group B (n=39) with manual suture in two sides, lateral end. In the postoperative period, an early evaluation was performed, analyzing local and systemic complications and late (average 5.6 y) analyzing deglutition. Results: Early evaluation: a) dehiscence of esophagogastric anastomosis n=5 (9.4%) in group A vs. n=9 (23.0%) in group B (p=0.0418); b) stenosis of esophagogastric anastomosis n=8 (15.1%) in group A vs. n=15 (38.4%) in group B (p=0.0105.); c) pulmonary infection n=5 (9.4%) in group A vs. n=3 (7.6%) in group B (p=1.0000.); d) pleural effusion n=5 (9.4%) in group A vs. n=6 (15.4%) in group B (p<0.518). Late evaluation showed that 86.4-96% of the patients presented the criteria 4 and 5 from SAEED, expressing effective swallowing mechanisms without showing significant differences among the groups. Conclusion: Cervical esophagogastric anastomosis by means of mechanical suture is more proper than the manual with lower incidence of local complications and, in the long-term evaluation, regular deglutition was acquired in both suture techniques in equal quality.

MECHANICAL SUTURE IN RECTAL CANCER

Background and aims. Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain genitourinary function by preservation of hypogastric nerves.Methods. In order to emphasize the importance of this surgical technique in the Fourth Surgical Clinic of the CF Clinical Hospital Cluj-Napoca, we conducted a prospective observational interventional study over a 3-year period (2013-2016) in 165 patients hospitalized for rectal and rectosigmoid adenocarcinoma in various disease stages, who underwent Dixon surgery using the two techniques of manual and mechanical end-to-end anastomosis. For mechanical anastomosis, we used Covidien and Panther circular staplers. The patients were assigned to two groups, group A in which Dixon surgery with manual end-to-end anastomosis was performed (116 patients), and group B in which Dixon surgery with mechanical end-to-end anastomosis was carried out (49 patients).Results. Mechanical anastomosis allowed to restore intestinal continuity following low anterior resection in 21 patients with lower rectal adenocarcinoma compared to 2 patients in whom intestinal continuity was restored by manual anastomosis, with a statistically significant difference (p<0.000001). The double-row mechanical suture technique is associated with a reduced duration of surgery (121.67 minutes for Dixon surgery with mechanical anastomosis, compared to 165.931 minutes for Dixon surgery with manual anastomosis, p<0.0001).Conclusion. The use of circular transanal staplers facilitates end-to-end anastomosis by double-row mechanical suture, allowing to perform low anterior resection in situations when the restoration of intestinal continuity by manual anastomosis is technically not possible, with the aim to preserve the anal sphincter, to restore intestinal function and maintain genitourinary function through preservation of hypogastric nerves.
