Routine splenic flexure mobilization (SFM) in colorectal surgery yields longer specimens for staging and reduces anastomotic leaks, despite similar operation times. This technique offers oncological and clinical benefits, potentially improving patient outcomes.
Area of Science:
- Colorectal Surgery
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Splenic flexure mobilization (SFM) is debated in laparoscopic and robotic colorectal surgery.
- Advocates cite improved colonic reach for tension-free anastomosis.
- Critics warn of increased complication risks and prolonged procedures.
Purpose of the Study:
- To evaluate the oncological and clinical advantages of routine SFM versus splenic flexure preservation (SFP).
- To assess the impact of SFM on specimen length, anastomotic integrity, and patient outcomes.
Main Methods:
- Retrospective cohort study of 94 patients undergoing anterior resection for malignant pathologies.
- Comparison of outcomes between SFM (65 patients) and SFP (29 patients) groups.
- Data collected over 24 months at New Cross Hospital, UK.
Main Results:
- SFM group had significantly longer resected specimens; lymph node counts and R0 resection rates were comparable.
- Hospital stay and operation duration were similar between groups.
- SFM group showed a trend towards higher stoma rates but significantly lower anastomotic leak incidence.
Conclusions:
- Routine SFM provides oncological benefits through more complete specimen retrieval for staging.
- SFM facilitates tension-free anastomosis, reducing the risk of anastomotic leaks.
- Surgeons may consider routine SFM for improved outcomes in colorectal resections.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Flexural Stress
