Ileocolic anastomosis after right hemicolectomy: stapled end-to-side, stapled side-to-side, or handsewn?

PURPOSE: Anastomotic leak (AL) following ileocolic anastomosis is a cause of significant morbidity and mortality. Stapled end-to-side (ESA), stapled side-to-side (SSA), and handsewn anastomoses (HSA) are commonly performed techniques. There is however conflicting data on the superiority of one technique over the other. The aim of this study was to compare the outcomes of ESA against SSA and HSA. METHODS: This retrospective cohort study was conducted at a tertiary colorectal unit. All patients who underwent an ileocolic anastomosis from October 2008 to May 2020 were included. Exclusion criteria were missing data on anastomotic technique or clinicopathological variables. Primary outcomes were AL and anastomotic bleeding (AB). Secondary outcomes were length of stay (LoS) and return of gut function. RESULTS: A total of 1390 patients met the inclusion criteria. A total of 976 (70%) ESA, 308 (22%) SSA, and 108 (8%) HSA were performed. AL occurred in 17/1390 (1.2%) patients, and 54/1390 (3.9%) had AB. On adjusted analysis, ESA experienced a lower AL when compared with SSA (OR 4.93, p = 0.005), with a trend towards a lower AL when compared to HSA (OR 2.6, p = 0.27). There was no difference in AB between all techniques: ESA vs. SSA (OR 1.07 p = 0.84), and ESA vs. HSA (OR 0.24 p = 0.76). Both stapled techniques were associated with a shorter return to gut function compared to HSA; 3.3 vs. 4.2 days (p < 0.001). There was no difference in LoS. CONCLUSION: ESA has the lowest leak rate when compared to other anastomotic techniques without any increased risk of anastomotic bleeding.

Challenges in creating dissectible anatomical 3D prints for surgical teaching.

Three-dimensional (3D) printing, or additive manufacturing, is now a widely used tool in pre-operative planning, surgical teaching and simulator training. However, 3D printing technology that produces models with accurate haptic feedback, biomechanics and visuals for the training surgeon is not currently available. Challenges and opportunities in creating such surgical models will be discussed in this review paper. Surgery requires proper tissue handling as well as knowledge of relevant anatomy. To prepare doctors properly, training models need to take into account the biomechanical properties of the anatomical structures that will be manipulated in any given operation. This review summarises and evaluates the current biomechanical literature as it relates to human tissues and correlates the impact of this knowledge on developing high fidelity 3D printed surgical training models. We conclude that, currently, a printer technology has not yet been developed which can replicate many of the critical qualities of human tissue. Advances in 3D printing technology will be required to allow the printing of multi-material products to achieve the mechanical properties required.

A Novel Technique for Sutureless Proximal Aortic Endograft Revision in Type 1A Endoleak.

Management of type 1A endoleaks can be challenging. In the endovascular era, this condition is expected to become more frequent. Conventionally, surgical explant of the endograft remains the "last-resort" surgical treatment when all endovascular or other open options are exhausted. Endograft removal is a difficult and morbid procedure. An alternative technique is described that involves cinching the endograft after disengagement of the proximal fixation hooks. The endograft is redeployed within a prosthetic aortic replacement graft with an overlapping zone. This can reduce complications such as from additional anastomoses, graft bleeding, prolonged clamping, operative time, and associated comorbidities.

Endoscopic Removal of a Fecalith or Fecomucolith in a Rectal Stump or Pouch.

Fecaliths or fecomucoliths can form in rectal stumps after a Hartmann procedure or in a coloneovaginal conduit. They can cause significant distress to the patient by causing symptoms such as discharge and odor. We describe a novel and effective method of endoscopic obliteration and removal where other techniques such as removal during examination under anesthesia or serial enemas have failed. By using a combination of hydrodissection with a saline injector gun and biopsy forceps and a polypectomy snare to break down the fecomucolith or fecalith, this troublesome problem can be resolved endoscopically. Successful removal of the fecalith/fecomucolith and resolution of the symptoms for the patients were achieved. No complications are reported. We describe an effective and novel method for endoscopic removal of fecaliths and fecomucoliths.

Modified Tightening for Figure-of-Eight Sternal Wiring Closure.

This is a simple and quick method for the tightening of figure-of-eight wires routinely used for sternal closure. This technique gives a stable approximation, adequate reduction, and immobilization, providing higher strength and rigidity compared with conventional figure-of-eight closure. The advantage of this technique is that it tightens all the four wires equally, thus avoiding loose loops.
