A new systematic review and meta-analysis compared robotic and conventional laparoscopic resection for transverse colon and splenic flexure cancers, among the more technically demanding locations for minimally invasive colorectal oncology. Surgery in this region requires precise management of variable middle colic and left colic vascular anatomy, mobilization across multiple abdominal quadrants, and careful dissection near the pancreas, spleen, stomach and major mesenteric vessels.
Six comparative non-randomized studies included 167 robotic and 296 laparoscopic patients. Overall morbidity, major morbidity, anastomotic leakage, reoperation and lymph-node yield were not significantly different between approaches.
The clearest observed difference involved conversion to open surgery. Among cases with relevant data, no conversion occurred in 149 robotic procedures compared with 14 conversions among 278 laparoscopic procedures. Robotic surgery was also associated with approximately one day shorter hospitalization.
Across 10 robotic series included in the broader analysis, pooled R0 resection rates were high, and studies reporting 30-day mortality recorded no deaths.
Surgical Relevance
Transverse colon and splenic flexure resections can challenge conventional laparoscopy because of multiquadrant operating, vascular variability and difficult angles for lymphovascular dissection. Robotic articulation, stable visualization and improved instrument control may be particularly useful in these circumstances.
However, the available comparative studies are non-randomized, and conversion events remain relatively few.
Clinical Takeaway: Robotics represents a reasonable minimally invasive option for technically challenging transverse colon and splenic flexure cancer and may reduce conversion in experienced hands, but prospective standardized evidence is required before concluding that robotics is oncologically or clinically superior to laparoscopy.

Low Indexed Oxygen Delivery Associated With Anastomotic Leakage After Laparoscopic Colorectal Cancer Surgery
A prospective observational cohort from Italy investigated indexed oxygen delivery (DO₂I) during elective laparoscopic colorectal cancer resection. Patients underwent noninvasive hemodynamic and oxygen-transport monitoring, allowing intraoperative calculation of systemic oxygen delivery relative to body surface area.
Three patients developed postoperative anastomotic leakage. Patients experiencing leakage demonstrated lower average indexed oxygen-delivery values, including one patient who recorded the lowest value in the entire cohort. Reduced oxygen delivery was also associated with a greater burden of postoperative surgical complications.
Although the number of leaks was small and causality cannot be established, the findings raise an important physiological question: whether optimizing systemic oxygen delivery during colorectal surgery could contribute to improved anastomotic healing.
Surgical Relevance
Anastomotic failure is traditionally discussed in terms of technical construction, tension, tissue perfusion, vascular division and patient-related risk factors. This study adds systemic oxygen transport as another potentially modifiable domain.
Adequate anastomotic healing depends not only on arterial inflow but also on hemoglobin concentration, cardiac output, oxygen saturation, microcirculation and tissue oxygen delivery.
The concept therefore complements—not replaces—technical perfusion assessment methods such as ICG fluorescence angiography and careful evaluation of bowel viability.
Clinical Takeaway: Anastomotic safety may depend on both local surgical technique and systemic physiology. Goal-directed optimization of oxygen delivery is biologically attractive, but interventional studies are required before specific DO₂I targets can be recommended for preventing colorectal anastomotic leakage.

Laparoscopic Repeat Hepatectomy Appears Feasible in Selected Patients With Recurrent Hepatocellular Carcinoma
A retrospective study evaluated 106 repeat hepatectomies for recurrent hepatocellular carcinoma (HCC), comparing laparoscopic repeat hepatectomy with open surgery or procedures requiring conversion.
Sixty-seven patients underwent laparoscopic repeat hepatectomy, while 39 underwent open or converted procedures. Importantly, patients in the open group had more challenging baseline characteristics, including larger tumors, greater use of anatomical resection and a higher frequency of previous open hepatic surgery. This substantial selection bias limits direct comparison.
Nevertheless, laparoscopic repeat hepatectomy demonstrated favorable short-term outcomes and was associated with improved recurrence-free and overall survival within this cohort.
The study also examined inflow-control strategy. Procedures performed without a Pringle maneuver were associated with shorter operative duration, reduced blood loss and fewer postoperative complications. These findings should not be interpreted as proof that avoiding inflow occlusion is intrinsically superior because case complexity likely influenced whether Pringle control was required.
Previous use of adhesion-prevention agents did not significantly alter operative duration, blood loss or postoperative morbidity.
Surgical Relevance
Repeat hepatectomy can be particularly demanding because previous surgery may produce adhesions, altered vascular anatomy, distorted hepatic planes and limited access to the hilum.
A minimally invasive approach may reduce the need for extensive adhesiolysis in selected patients, particularly when recurrent tumors are favorably located.
Clinical Takeaway: Repeat laparoscopic hepatectomy is a reasonable option for selected recurrent HCC, but success depends on previous operative route, tumor location and burden, anticipated adhesions, liver reserve, vascular-control strategy and readiness for conversion when safe progression cannot be maintained.

Robotic Surgery May Improve Ergonomics for Both Surgeons and Surgical Assistants
A prospective observational study evaluated ergonomic symptoms following robotic and conventional laparoscopic upper-GI and colorectal procedures. Ninety-two operations were assessed, with questionnaires completed by both primary surgeons and surgical assistants.
After adjustment for procedure type, robotic surgery was associated with lower perceived musculoskeletal symptom scores across several domains among primary surgeons, including reduced back and lower-extremity discomfort.
Importantly, ergonomic benefits were not limited to the console surgeon. Surgical assistants also demonstrated favorable trends, particularly regarding shoulder discomfort, postural strain and physical fatigue.
These findings remained directionally consistent after sensitivity analyses accounting for operative duration and perceived procedural complexity.
Surgical Relevance
Conventional laparoscopy can expose surgeons to prolonged neck rotation, static shoulder elevation, wrist deviation, instrument torque and fixed standing posture. Over years of high-volume operating, cumulative musculoskeletal strain can contribute to pain, fatigue and occupational injury.
Ergonomics also affects concentration, fine motor performance, teaching ability and career longevity.
This study importantly reframes robotic ergonomics as a whole-team consideration, rather than focusing exclusively on the seated console surgeon.
Clinical Takeaway: Robotic surgery may provide ergonomic advantages for both primary surgeons and assistants, but operating-room layout, assistant-port positioning, table height, monitor placement and team workflow remain essential determinants of musculoskeletal safety regardless of platform.

Six-Hour Structured Ex Vivo Curriculum Improves Laparoscopic Suturing Performance
The MAESTRO pilot project evaluated a compact structured training program designed to improve minimally invasive suturing performance among surgical residents.
Six residents underwent baseline assessment in intracorporeal knot tying and continuous laparoscopic suturing, followed by six hours of interval training distributed across two months using a laparoscopic trainer.
Recorded performances were independently evaluated by blinded raters using the validated Laparoscopic Suturing Competency Assessment Tool.
Following training, overall competency scores improved significantly, with measurable gains in instrument handling, tissue handling and reduction of technical errors.
The study is small, involves only six participants and lacks a control group. Nevertheless, it demonstrates how even a relatively short curriculum may produce measurable improvement when training is structured, distributed and objectively assessed.
Surgical Relevance
Intracorporeal suturing remains one of the major technical bottlenecks in advanced laparoscopy. Competence is essential for enterotomy repair, bowel anastomosis, intracorporeal knotting, myomectomy closure, hiatal reconstruction, hernia surgery and management of intraoperative complications.
The study provides a practical framework for training units:
defined tasks → distributed practice → recorded performance → blinded assessment → competency scoring → targeted feedback.
Clinical Takeaway: Laparoscopic suturing should be taught through structured deliberate practice and objective competency assessment rather than relying solely on opportunistic operating-room exposure.

Post-Cholecystectomy Nutrition Review Supports Risk-Stratified Recovery Pathways
A narrative review in Frontiers in Surgery summarizes available evidence and guideline-informed practice regarding nutritional management after cholecystectomy, particularly following laparoscopic surgery.
For uncomplicated patients, the review supports early oral intake within approximately 24 hours when clinically appropriate, consistent with modern enhanced-recovery principles. Routine prolonged fasting or highly restrictive postoperative diets are generally unnecessary for most uncomplicated patients.
However, nutritional recovery should be individualized in patients with complicated acute cholecystitis, recent biliary pancreatitis, advanced age, obesity, diabetes, pre-existing malnutrition or other metabolic vulnerabilities.
The review also discusses persistent post-cholecystectomy symptoms such as diarrhea, dyspepsia, abdominal bloating and altered tolerance of dietary fat. Selected patients with prolonged symptoms may require further assessment rather than repeated empirical dietary restriction.
Potential concerns regarding fat-soluble vitamins are also discussed, although the authors emphasize that much of the available evidence is extrapolated and requires cholecystectomy-specific validation.
Surgical Relevance
Laparoscopic cholecystectomy is frequently treated as a routine day-care procedure, yet postoperative recovery is not identical for every patient.
A healthy patient undergoing uncomplicated elective surgery may require little more than early feeding, mobilization and standard discharge advice, whereas elderly, diabetic, nutritionally vulnerable or complicated biliary patients may benefit from structured follow-up.
Clinical Takeaway: Post-cholecystectomy nutrition should be risk-stratified rather than universally restrictive. Early oral feeding is appropriate for most uncomplicated patients, while persistent gastrointestinal symptoms or high-risk clinical circumstances warrant individualized assessment and follow-up.
