lower anterior resection technique

This study presents a new technique for robotic-assisted intracorporeal rectal transection and hand-sewn anastomosis for low anterior resection that overcomes some limitations of conventional techniques. By integrating the advantages of the robotic platform, ensuring standardized exposure during rectal transection, and emphasizing the importance of avoiding complications associated with staple crossings, this innovation has the potential to significantly improve outcomes and reduce costs for patients with lower rectal tumors...

BACKGROUND AND OBJECTIVES: Anastomotic leakage is a serious complication following surgery for cancer of the rectum. It is not clear whether reinforcing sutures could prevent anastomotic leakage. Therefore, this study aims at evaluating the efficacy of reinforcing sutures on anastomotic leakage. METHODS: We searched PubMed, Embase, and the Cochrane Library databases from inception to January 31, 2023. We included studies comparing anastomosis with reinforcing sutures to anastomosis without reinforcing sutures after low anterior resection...

Till the day the rectal cancer deaths in the world is in eighth position. For rectal cancer surgery, short-term benefits are expected to be similar for laparoscopic resection of rectum (LRR) and open resection of rectum (ORR). In Bangladesh though the rectal cancer is the sixteenth most common cause of cancer deaths, there is lack of data regarding outcomes of laparoscopic and open surgical approaches for carcinoma rectum. Purpose of study was to compare oncopathological outcomes by quality of surgical resection between LRR and ORR groups...

UNLABELLED: Video-assisted thoracic surgery (VATS) has been growing in popularity over the past 2 decades as an alternative to open thoracotomy for the treatment of several spinal conditions, and in the field of minimally invasive surgery, it now acts as a keyhole to the thoracic spine. MATERIALS AND METHODS: Most VATS approaches are from the right side for pathologies involving the middle and upper thoracic spine because there is a greater working spinal surface area lateral to the azygos vein than that lateral to the aorta...

PURPOSE: There is lack of intraoperative consensus on the distal femur anterior resected surface shape that allows reliable rotational alignment assessment during total knee arthroplasty (TKA). We aimed to evaluate the ratio and prevalence of anterior femoral resection surface intraoperatively. MATERIALS AND METHODS: The study included 234 osteoarthritis patients with varus knees and not valgus knees or deformities. After conventional medial parapatellar approach, measured resection technique based on the mechanical axis of the femur and preoperative TEA-PCA angle on CT with anterior reference was used among all the patients...

Minimally invasive colorectal surgery is currently well-accepted, with open techniques being reserved for very difficult cases. Laparoscopic colectomy has been proven to have lower mortality, complication, and ostomy rates; a shorter median length of stay; and lower overall costs when compared to its open counterpart. This trend is seen in both benign and malignant indications. Natural orifice specimen extraction surgery (NOSES) in colorectal surgery was first described in the early 1990s. Three recent meta-analyses comparing transabdominal extraction against NOSES concluded that NOSES was superior in terms of overall postoperative complications, recovery of gastrointestinal function, postoperative pain, aesthetics, and hospital stay...

AIM: Surgeons often have strong opinions about how to perform colorectal anastomoses with little data to support variations in technique. The aim of this study was to determine if location of the end-to-end (EEA) stapler spike relative to the rectal transection line is associated with anastomotic integrity. METHOD: This study was a retrospective analysis of a quality collaborative database at a quaternary centre and regional hospitals. Patients with any left-sided colon resection with double-stapled anastomosis were included (December 2019 to August 2022)...

BACKGROUND: The aim of this study was to investigate whether the robotic platform can have a positive impact on the rate of sphincter preservation in patients with rectal tumors, undergoing robotic total mesorectal excision (TME), in comparison with laparoscopic or open TME. We also analyzed and compared short-term outcomes. METHODS: A prospectively collected robotic database was reviewed and compared with the trust and national data. Three groups were designed according to the surgical technique: open, laparoscopic and robotic...

Background: Low anterior resection syndrome (LARS) is a bowel dysfunction following sphincter-sparing proctectomy. The occurrence of LARS may affect a patient's overall quality of life (QoL) after surgery. Current research was aimed to investigate related factors of LARS and major LARS in total mesorectal excision (TME) and its relationship with QoL. Methods: This study included patients who underwent TME at authors' institutes. LARS was evaluated with an LARS score. QoL was identified using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire, version 3...

Mucinous cystic tumors of low malignant potential (MCTLMP) are rare urachal neoplasms. The morphological characteristics and clinical prognosis of MCTLMP is similar to that of mucinous cystic tumors occurring in the ovary and appendix. After complete resection, almost no cases of recurrence or metastasis have been reported. Because MCTLMP is rare, it may be missed in the clinic. MCTLMP can lead to the formation of pseudomyxoma peritonei (PMP), which manifests as the widespread production of mucus in the abdominal cavity and makes the disease complex or difficult to diagnose...

BACKGROUND: The surgical resection of rectal carcinoma is associated with a high risk of permanent stoma rate. Primary anastomosis rate is suggested to be higher in robot-assisted and transanal total mesorectal excision, but permanent stoma rate is unknown. METHODS: Patients undergoing total mesorectal excision for MRI-defined rectal cancer between 2015 and 2017 in 11 centers highly experienced in laparoscopic, robot-assisted or transanal total mesorectal excision were included in this retrospective study...

For transanal total mesorectal excision (TaTME), the indication for single-stapling technique (SST) has been expanded to include lower anastomosis, even in intersphincteric resection (ISR). We focused on the anastomotic techniques following ISR with TaTME and examined the feasibility and safety of the SST below the anorectal junction (ARJ). Data on postoperative anastomosis-related complications and anorectal function was evaluated in comparison to conventional manual hand-sewn coloanal anastomosis in ISR with TaTME...

BACKGROUND: The most common postoperative complication in malignant rectal surgery is anastomotic leakage (AL). AL after anterior or low anterior resection in rectal tumors is a fatal postoperative complication. Recently, the first automated suture circular stapler, which is expected to reduce the incidence of AL, (J&J). MATERIALS AND METHODS: This study included a total of 248 rectal tumor patients who underwent double stapler technique (DST) anastomotic procedures in the department of gastroenterological surgery /pediatric surgery at Gifu University School of Medicine from January 2017 to December 2021...

OBJECTIVE: This study investigated the therapeutic effect of laparoscopic surgery combined with the plasma electric cutting knife on patients diagnosed with rectal cancer and its impact on serum inflammatory factors in the bloodstream. METHODS: The researchers examined the clinical data of 85 patients who underwent laparoscopic low anterior resection for rectal cancer in our hospital from April 2020 to December 2021. The patients comprised two groups: an observation group of 40 cases and a control group of 45 cases...

BACKGROUND: Laparoscopic anterior rectal resection (LAR) is a commonly performed surgery for rectal cancer patients. Pelvic floor peritoneum closure (PC), a vital procedure in conventional anterior rectal resection, is not routinely performed in LAR. STUDY DESIGN: A total of 1118 consecutive patients with rectal cancer receiving LAR were included in this retrospective study. Patients were allocated into the PC group and the non-PC group. The occurrence of postoperative complications was compared between the 2 groups...

BACKGROUND: Recently, smaller-size trocars and instruments have been developed for laparoscopic colon cancer surgery; however, their effectiveness and safety have not been elucidated. This study aimed to investigate whether 3 mm trocars and instruments have benefits compared with conventional trocars and instruments. PATIENTS AND METHODS: Patients with colon cancer who underwent laparoscopic anterior resection or right hemicolectomy were included. Patients who underwent combined resections of other organs and those with conversion to open surgery were excluded...

Diverticulitis is a common colorectal disease present in Western countries that develops as infected protrusions (diverticula) along weak points in the colon due to increased intraluminal pressure. Most patients with diverticular disease can be asymptomatic; however, several complications can arise from the development of diverticulitis. Here, we discuss the diagnosis and management of a patient presenting with recurrent Escherichia coli ( E. coli ) vaginal infections due to sigmoid colon diverticulitis resulting in a colo-fallopian fistula that was unremarkable on diagnostic imaging...

INTRODUCTION: There is an ongoing debate on surgical techniques for colorectal deep endometriosis (DE) and their effects on gastrointestinal (GI) function. The aim of this study was to prospectively investigate the differences in pre- and postsurgical GI function, health profiles and pain symptoms in women undergoing colorectal surgery for symptomatic DE either with a modified segmental resection technique, so-called nerve-vessel sparing segmental resection (NVSSR), or full thickness discoid resection (FTDR)...

BACKGROUND: The adoption of minimally invasive techniques to perform mitral valve repair surgery is increasing. This is enhanced by the compelling evidence of satisfactory short-term results and lower major morbidity. We analyzed mid-term follow-up results of our experience, and further compared two techniques: isolated leaflet resection and neochord implantation for posterior leaflet prolapse. METHODS: Data for all consecutive endoscopic mitral valve repairs via video-assisted right anterior mini-thoracotomy were analyzed between December 2012 and September 2021...

The incidence of intra-articular ganglion cysts of the anterior cruciate ligament (ACL) is low and symptomatic presentation of this pathology is even lower. Nevertheless, symptomatic cases pose a real challenge for the orthopaedic community, as no general consensus exists regarding the most appropriate treatment. The purpose of this Technical Note is to describe the surgical treatment of an ACL ganglion cyst by arthroscopic resection of the entire posterolateral bundle of the ACL in a figure-of-four position after conservative treatment has failed...
