intestinal anastomosis

This case report describes necrotizing enterocolitis (NEC) in an infant with a history of twin-twin transfusion syndrome (TTTS). TTTS is a volume imbalance where the anastomosis at the vascular equator between the two placentae shifts from the donor to the recipient twin. This causes a higher risk for NEC, a marked inflammation caused by bacterial infection into the intestinal wall, from prematurity and intestinal hypoperfusion. Complications include sepsis, bowel necrosis, perforation, peritonitis, and death...

OBJECTIVE: To create a method of two-stage repair of high unformed conglomerate delimited debilitating jejunal fistulas via posterolateral laparotomy with low risk of surgical complications. MATERIAL AND METHODS: Methodology and treatment outcomes were analyzed in 37 patients with unformed conglomerate high debilitating delimited jejunal fistulas. Of these, 22 patients underwent one-stage treatment through 2 converging incisions and/or two-stage treatment through anterolateral access...

KEY CLINICAL MESSAGE: Duodenal GISTs are rare and challenging tumors. Acute life-threatening upper GI bleeding is a possible presentation of duodenal GISTs. Surgery is the standard treatment for localized duodenal GISTs. Imatinib is an effective adjuvant therapy for duodenal GISTs. ABSTRACT: GIST is the most common mesenchymal neoplasm of the gastrointestinal tract, accounting for 1%-2% of gastrointestinal tumors. They originate from the interstitial cells of Cajal and are rare in patients younger than 30 years...

Anastomosis is a common and critical part of reconstructive procedures within gastrointestinal, urologic, and gynecologic surgery. The use of autonomous surgical robots such as the smart tissue autonomous robot (STAR) system demonstrates an improved efficiency and consistency of the laparoscopic small bowel anastomosis over the current da Vinci surgical system. However, the STAR workflow requires auxiliary manual monitoring during the suturing procedure to avoid missed or wrong stitches. To eliminate this monitoring task from the operators, we integrated an optical coherence tomography (OCT) fiber sensor with the suture tool and developed an automatic tissue classification algorithm for detecting missed or wrong stitches in real time...

OBJECTIVES: Limited data are available on patients with advanced-stage epithelial ovarian cancer (OC) who require ostomy during primary cytoreductive surgery. This study aimed to investigate the application of postoperative and long-term oncological results from transitory protective stoma (TPS) formation during primary debulking surgery (PDS) for OC. METHODS: This is a retrospective cohort study with a single center. We identified patients with stage III-IV OC who underwent colon resection and anastomosis...

BACKGROUND: The use of high-frequency electric welding technology for intestinal end-to-end anastomosis holds significant promise. Past studies have focused on in vitro, and the safety and efficacy of this technology is uncertain, severely limiting the clinical application of this technology. This study investigates the impact of compression pressure, energy dosage, and duration on anastomotic quality using a homemade anastomosis device in both in vitro and in vivo settings. METHODS: Two hundred eighty intestines and 5 experimental pigs were used for in vitro and in vivo experiments, respectively...

Cancer is a well-recognized risk factor for thromboembolic events and thromboembolism. This case report presents the rare coexistence of rectal carcinoma and pulmonary artery thrombosis in a female patient. A 44-year-old female presented with complaints of abdominal pain, vomiting, and obstipation. She had recently been diagnosed with rectal carcinoma. She had not undergone any invasive procedures in the past. Given the possibility of intestinal obstruction, an exploratory laparotomy was performed, followed by retrocolic gastrojejunostomy with Roux-en-Y anastomosis with a feeding JT tube insertion...

The occurrence of small intestinal diverticula is relatively infrequent compared to its counterpart in the large bowel. Duodenal diverticula exhibit a significantly higher prevalence within the small intestine compared to jejunoileal diverticula, with a ratio of five to one. The occurrence of jejunoileal diverticula exhibits considerable variability and has been documented to range from 0.5% to 2.3% in radiographic series, while autopsy studies have reported rates as high as 7%. We present the clinical details of a 65-year-old male patient who sought medical attention due to a constellation of symptoms, including abdominal pain, vomiting, and obstipation...

INTRODUCTION AND IMPORTANCE: Intestinal duplication is an uncommon congenital malformation affecting the alimentary tract. This article presents a case of enteric duplication cyst (EDC) in an adult, accompanied by a review of the available literature. CASE PRESENTATION: A 34-year-old woman with polymyositis underwent a routine CT scan as part of her medical assessment revealing an 8 cm mass near the caecum and terminal ileum. Diagnostic procedures confirmed a cystic spherical mass...

Ulcerative colitis (UC) has a more severe presentation and rapid progression in pediatric patients, resulting in a greater need for surgical intervention compared to adults. Though medical management of UC has advanced with new biologic therapies, surgery continues to play an important role when disease progresses in the form of worsened or persistent symptoms, hemodynamic instability, or sepsis. The goals of surgical management are to restore intestinal continuity with a functional pouch when possible. While the literature has been growing regarding studies of pediatric patients with UC, high level of evidence studies are limited and most recommendations are based on adult studies...

PURPOSE: Gastrointestinal disorders frequently necessitate surgery involving intestinal resection and anastomosis formation, potentially leading to severe complications like anastomotic leakage (AL) which is associated with increased morbidity, mortality, and adverse oncologic outcomes. While extensive research has explored the biology of anastomotic healing, there is limited understanding of the biomechanical properties of gastrointestinal anastomoses, which was aimed to be unraveled in this study...

Ulcerative colitis is an inflammatory disease of the colon, characterized by a chronic relapsing course, affecting only the colon with hemorrhagic-purulent inflammation of the mucous and submucosal layer of the intestinal wall, as well as the frequent development of local and systemic complications. The incidence of ulcerative colitis is increasing every year. Objective - improving the results of surgical treatment of ulcerative colitis in children through the use of laparoscopic and video-assisted technologies in clinical practice...

BACKGROUND: Acute mesenteric ishemia(AMI) is a rare but very serious disease with high rate of mortality and morbidity. About 1-2% of all gastrointestinal disease is AMI. Mortality is about 60-80% and depends of time between starting of symptoms and establishing of diagnosis, type AMI, comorbidities. AMI is often in older population with coronary syndrom and atrial fibrilation. AMI may be occlusive(embolisatio arteriae mesentericae superior(AMS), or thrombosis of AMS, mesenterial vein thrombosis) and nonoclusive form(NOMI)...

Roux-en-Y gastric bypass (RYGB) patients are at risk of creating potential spaces for possible internal hernias during the procedure. During pregnancy, the pregnant uterus elevates the bowel, increasing intra-abdominal pressure. Cases reported to date have described mild abdominal pain and no evidence of peritoneal irritation, with inconclusive ultrasound and MRI findings for diagnosis of Petersen's hernia. We present the case of a 42-year-old female patient with a history of RYGB eight years earlier without complications, with a pregnancy of 34 weeks of gestation...

PURPOSE: Anastomotic leakage after anterior resection for rectal cancer induces bowel dysfunction, but the influence on urinary and sexual function is largely unknown. This cross-sectional cohort study evaluated long-term effect of anastomotic leakage on urinary and sexual function in male patients. METHODS: Patients operated with anterior resection for rectal cancer in 15 Swedish hospitals 2007-2013 were identified. Anastomotic leakage and other clinical variables were retrieved from the Swedish Colorectal Cancer Registry and medical records...

Few cases of spontaneous bowel evisceration (SBE) through umbilical hernias (UHs) in adult patients have been reported in the literature. Interestingly, the spontaneous rupture of the hernia sac is a rare complication usually seen in adult cirrhotic patients with persistent ascites or in patients with congenital wall defects. A man in his early 50s was admitted to our emergency department with SBE through a long-standing acquired UH. He was not clinically cirrhotic, although being HCV positive. Surgeons performed an urgent laparotomy with ileal resection, latero-lateral ileal anastomosis and direct hernioplasty without mesh...

BACKGROUND: Although intracorporeal anastomosis (IA) for colon cancer requires longer operative time than extracorporeal anastomosis (EA), its short-term postoperative results, such as early recovery of bowel movement, have been reported to be equal or better. As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum, there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells...

BACKGROUND: Abdominal cocoon syndrome (ACS) represents a category within sclerosing encapsulating peritonitis, characterized by the encapsulation of internal organs with a fibrous, cocoon-like membrane of unknown origin, resulting in bowel obstruction and ischemia. Diagnosing this condition before surgery poses a challenge, often requiring confirmation during laparotomy. In this context, we depict three instances of ACS: One linked to intestinal obstruction, the second exclusively manifesting as intestinal ischemia without any obstruction, and the final case involving a discrepancy between the radiologist and the surgeon...

BACKGROUND: Ostomy is a common surgery usually performed to protect patients from clinical symptoms caused by distal anastomotic leakage after colorectal cancer (CRC) surgery and perforation or to relieve intestinal obstruction. AIM: To analyze the complications after transverse colostomy closure. METHODS: Patients who underwent transverse colostomy closure from Jan 2015 to Jan 2022 were retrospectively enrolled in a single clinical center...

INTRODUCTION: Angiodysplasia, a rare cause of gastrointestinal (GI) bleeding, presents a spectrum of clinical manifestations from anemia to life-threatening hemorrhage. This case study emphasizes the significance of considering intestinal vascular malformations as a differential diagnosis, especially in the context of chronic anemia and GI bleeding. Jejunal angiodysplasia, though infrequent, poses diagnostic challenges due to the hidden nature of the small bowel in the GI system. CASE PRESENTATION: A 23-year-old male presented with acute hematochezia and melena, necessitating prompt intervention...
