The purpose of this study was to identify the main surgical factors affecting long-term Quality of life (QoL) among colorectal cancer patients after surgery. : QoL was prospectively evaluated in patients undergoing elective colorectal cancer resection operations in three CRC surgery centers of Lithuania using EORTC generic (QLQC-30) and disease-specific (QLQ-CR29) questionnaires at the time of preoperative admission and 1, 24, and 72 months after surgery.

Comprehensive testing of colorectal anastomosis: results of prospective observational cohort study.

Background: Anastomotic leakage remains one of the most threatening complications in colorectal surgery. Intraoperative testing of anastomosis may reduce the postoperative anastomotic leakage rates. This study aimed to investigate a novel comprehensive intraoperative colorectal anastomosis testing technique to detect the failure of the anastomosis construction and to reduce the risk of postoperative leak.

Short and long-term outcomes of elderly patients undergoing left-sided colorectal resection with primary anastomosis for cancer.

Background: The proportion of elderly colorectal cancer (CRC) patients requiring surgery is increasing. Colorectal resection for left-sided cancers is the most controversial as the primary anastomosis or end-colostomy and open or minimally invasive approaches are available. Therefore, this study was conducted to investigate the short- and long-term outcomes in elderly patients after resection with primary anastomosis for left-sided CRC.

Experimental Study of Mechanical Integrity Testing in Stapled Large Bowel: Methylene Blue Leak Test Is Not Inferior to Air Leak Test.

Background/objectives: Anastomotic leakage remains the most devastating postoperative complication in colorectal surgery. The mechanical integrity of the newly formed colorectal anastomosis can be evaluated by visual inspection intraoperatively; both air leak and liquid leak tests are also used to evaluate the integrity of stapled colorectal anastomoses. It is not clear whether double-stapled anastomoses are more prone to leaks than single-stapled anastomoses.

Intraoperative testing of colorectal anastomosis and the incidence of anastomotic leak: A meta-analysis.

Background: AL remains one of the most threatening complications in colorectal surgery. Significant efforts are put to understand the pathophysiological mechanisms involved in the development of leakage and to create the strategies to prevent it. We aimed to determine whether intraoperative testing of mechanical integrity and perfusion of colorectal anastomosis could reduce the incidence of AL.

Risk factors for anastomotic leakage and its impact on long-term survival in left-sided colorectal cancer surgery.

Background: Anastomotic leakage (AL) significantly impairs short-term outcomes. The impact on the long-term outcomes remains unclear. This study aimed to identify the risk factors for AL and the impact on long-term survival in patients with left-sided colorectal cancer.

High-grade well-differentiated neuroendocrine tumour of the cecum diagnosed following incisional hernia repair: a case report.

High-grade well-differentiated neuroendocrine tumour tumours (NETs) of gastrointestinal tract are rare; they can arise in any part of the digestive system and usually present in advanced stages. Low incidence and wide heterogeneity in the biological behaviour of such lesions pose a diagnostic and therapeutic challenge. Loco-regional NETs should be resected whenever feasible, potentially with a curative intent.

The problem of colorectal anastomosis safety.

Introduction: Anastomotic leakage (AL) remains one of the most threatening complications in colorectal surgery with the incidence of up to 20%. The aim of the study is to evaluate the safety and feasibility of novel - trimodal intraoperative colorectal anastomosis testing technique.

Transanal Total Mesorectal Excision: Is There a Real Advantage? The Baltic View.

Background: The novel surgical procedure transanal total mesorectal excision (taTME) has rapidly become an interest of research in order to overcome the shortcomings of laparoscopic surgery in the treatment of middle and low rectal cancer. taTME is a new natural orifice transluminal endoscopic surgery modality combining three rectal surgery techniques.

Methods: A retrospective clinical study was conducted in a single centre for a period of 3 years, and herein we report on our first 25 taTME procedures in patients with middle and lower third rectal adenocarcinoma.

Case report: Laparoscopic approach in the treatment of presacral lipoma.

Retrorectal lipoma, as well as other retrorectal tumours, is a relatively rare disorder. Retrorectal tumours accounted for 1 in 40,000 hospital admissions. We present a case of retrorectal lipoma, 15 cm × 10 cm × 8 cm in size, treated by the laparoscopic approach.

Does a retrorectal tumour remain a challenge for surgeons?

Retrorectal tumours are lesions with a wide range of histological differentiation that are often diagnostic and clinical challenges due to their rare occurrence. Many cases of this pathology are treated in regional hospitals, which results in serious complications because physicians fail to recognize this pathology. We present our experience in treating these tumours.

Long-Term Outcomes after Surgery for Appendiceal Mucinous Tumours.

Purpose: To compare perioperative colorectal cancer care and survival in patient cohorts operated in 2005 and in 2010 in Lithuania.

Methods: Comparative observational cohort study was performed. The study was conducted in the three Lithuanian cancer hospitals.

Fecal incontinence after transanal endoscopic microsurgery.

Purpose: Transanal endoscopic microsurgery (TEM) procedure could potentially influence the development of fecal incontinence later in life. The aim of our study was to assess long-term functional outcomes after TEM and to determine possible variables related to incontinence.

Methods: Patients, enrolled in a prospectively collected TEM operation database, were interviewed using a postal questionnaire.

Enterogenous cyst of the small bowel mesentery: a case report and review of the literature.

Introduction: Enterogenous cysts are a very rare congenital abnormality that can be found anywhere within the gastrointestinal tract, most commonly in the small intestine. The incidence is approximately one in 4500-10,000 live births. Diagnosis can be suggested by ultrasound (US), computed tomography (CT) scans or magnetic resonance imaging (MRI) findings, although histological examination confirms the definitive diagnosis.

Laparoscopically assisted colonoscopic polypectomy - viable option for curative surgery in elderly patients.

Introduction: Colorectal cancer (CRC) is the third most common cancer worldwide and the fourth most frequent cause of cancer-related death in the world. CRC screening programs have been widely introduced worldwide, allowing for early detection and removal of precancerous lesions and avoiding major surgical intervention. However, not all polyps are suitable for conventional and advanced colonoscopic polypectomy.

Is acute appendicitis still misdiagnosed?

Objective: The optimal diagnostics and treatment of acute appendicitis continues to be a challenge. A false positive diagnosis of appendicitis may lead to an unnecessary operation, which has been appropriately termed negative appendectomy. The aim of our study was to identify the effectiveness of preoperative investigations in preventing negative appendectomy.

Multiple gastrointestinal metastases of Merkel cell carcinoma.

Merkel cell carcinoma is an aggressive skin malignancy. Primary Merkel cell carcinomas are treated by wide radical excision with or without adjuvant radiotherapy, while benefits of adjuvant chemotherapy remain doubtful. There are only several cases of gastrointestinal metastases of Merkel cell carcinoma reported so far.

C-reactive protein is a predictor of complications after elective laparoscopic colorectal surgery: five-year experience.

Introduction: With the development and improvement of laparoscopic surgery, procedures have become common. However, post-operative complications occur when patients are released from hospital. These complications increase patients' morbidity and mortality.
