This study looked at the results of laparoscopic colectomy, a minimally invasive surgery for colon issues, in younger (ages 19-65) and older patients (over 65) using data from 2013. It found that patients who had laparoscopic surgery were 20% less likely to be readmitted to the hospital within 30 days, had shorter hospital stays (1.46 days less), and overall lower costs, with younger patients benefiting more than older ones. For younger patients, the surgery led to fewer discharges to nursing facilities or needing home health care compared to older patients.
Who this helps: This research benefits patients, especially younger adults undergoing colon surgery.

Plain English
This study looked at whether a microbial sealant could reduce the risk of surgical site infections (SSI) in patients undergoing clean-contaminated colorectal surgeries. The research included 100 patients, with 50 using the sealant and 50 not using it, and found that the infection rates were 14% in the sealant group compared to 10% in the control group, which means the sealant didn’t make a difference. This is important because it suggests that using microbial sealants in these surgeries is not helpful for preventing infections, even with standardized care.

This study looked at the use of a skin patch with fentanyl to help manage pain after hemorrhoid surgery. It found that patients using the fentanyl patch had significantly less pain and needed fewer narcotics compared to those who received a placebo. Specifically, 10 out of 17 patients on fentanyl required additional pain relief, compared to all 21 patients in the placebo group, and they consumed far less narcotic medication overall (about 97 mg versus 236 mg). This matters because it shows that fentanyl patches can effectively reduce pain and decrease reliance on stronger narcotics after surgery.
Who this helps: This helps patients recovering from hemorrhoid surgery.
Diseases of the colon and rectum
Cataldo PA, Senagore A, Luchtefeld MA
Plain English
This study looked at how effective intrarectal ultrasound (IRUS) is for diagnosing perirectal abscesses in 24 patients. The researchers found that IRUS accurately identified all 19 patients with abscesses before surgery, and 63% of the time, it correctly showed how the abscesses were related to the sphincters. However, IRUS was less reliable in finding openings of fistulas, identifying them only in 28% of cases.
Who this helps: This helps doctors better diagnose and treat patients with complex anal conditions.
Diseases of the colon and rectum
Senagore A, Mazier WP, Luchtefeld MA, MacKeigan JM, Wengert T
Plain English
This study compared two methods for treating hemorrhoids: using a cold scalpel versus a Nd:YAG laser. Researchers looked at 86 patients and found that while there was no significant difference in most outcomes, those treated with the laser experienced more wound inflammation and issues at the 10-day check-up, with an average score of 1.7 compared to 0.8 for the scalpel group. Additionally, using the laser cost $15,360 more overall, indicating that the laser offers no real advantages for patient care compared to the scalpel.
Who this helps: This helps patients by highlighting the benefits of traditional scalpel treatment over more expensive laser procedures.
Diseases of the colon and rectum
Senagore A, Milsom JW, Walshaw RK, Dunstan R, Chaudry IH
Plain English
This study looked at how a specific type of surgical procedure called a proximal colostomy might impact the healing of connections made in the colon after surgery, using pigs as test subjects. Researchers found that there was no significant difference in healing outcomes, like blood flow or inflammation, between pigs with and without the colostomy. However, the pigs with colostomies had weaker connections at 11 days after surgery but not later on, which shows that colostomy doesn't seriously harm healing overall.
Who this helps: This research helps doctors and surgeons making decisions about colorectal surgeries.
Regional anesthesia
Schnitzler M, Kilbride MJ, Senagore A
Plain English
This study looked at how epidural pain relief using local anesthetics and narcotics affects the healing of surgical connections in the colon in pigs. The results showed that pigs receiving bupivacaine or morphine had faster recovery of bowel movement compared to those given a saline solution, with transit times of about 4 days for the pain relief groups versus 6 days for the saline group. Importantly, all groups healed well without complications, indicating that using epidural pain relief is a safe option after colon surgery.
Who this helps: This helps patients recovering from colorectal surgery by providing effective pain management without delaying healing.
Diseases of the colon and rectum
Senagore A, Milsom JW, Walshaw RK, Dunston R, Chaudry IH
Plain English
This study looked at two different surgical methods for connecting intestines in pigs: a hand-sewn technique and a circular stapling technique. Researchers found no significant differences in how well the intestines healed, as both methods showed similar blood flow, healing scores, and there were no complications like leaks. This matters because it shows that both techniques are equally effective, which can help surgeons choose the best method without worrying about healing differences.
Who this helps: Patients undergoing colorectal surgery.
The Journal of surgical research
Milsom JW, Senagore A, Walshaw RK, Mostosky UV, Wang P +2 more
Plain English
This study examined how preoperative radiation therapy affects healing after surgery for rectal cancer in female pigs. Researchers found that pigs who received radiation had lower blood flow to the surgical area compared to those that did not, which led to more complications: 7 out of 24 pigs that had radiation developed issues versus only 2 out of 24 in the control group. These findings matter because reduced blood flow can slow down healing and increase the risk of problems after surgery.
Who this helps: This helps doctors planning treatment for rectal cancer patients.
Diseases of the colon and rectum
Senagore A, Milsom JW, Walshaw RK, Dunstan R, Mazier WP +1 more
Plain English
This study looked at how to better predict healing after colorectal surgery by measuring blood flow and pH levels in the intestines. Researchers found that measuring pH levels was much better at predicting complications after surgery, with a success rate of 93% compared to 70% for blood flow measurements. This is important because it could help doctors identify at-risk patients and improve recovery outcomes after such surgeries.
Who this helps: Patients undergoing colorectal surgery.

Plain English
This study examined the safety of inserting pulmonary artery catheters (PACs) through two different sites: the internal jugular and the subclavian veins. Researchers found that both methods had similar complication rates, with serious complications occurring in 3% of cases and initial infections at 2%, which increased to 8% and 15% for second catheters placed over a guidewire or at a new site, respectively. This is important because it shows that using a careful and sterile technique for catheter insertion keeps the risk of complications low, allowing for safe replacements after three days.
Who this helps: This benefits patients needing long-term heart monitoring.
Pediatric research
Karna P, Senagore A, Chou CC
Plain English
Researchers studied how asphyxia, low oxygen (hypoxia), and high acidity (acidosis) affect blood flow and oxygen usage in the intestines of newborn piglets. They found that asphyxia and low oxygen decreased blood flow to the intestines significantly, with blood flow dropping to about 50% of normal levels, and caused intestinal damage similar to what is seen in human newborns with a serious condition called necrotizing enterocolitis. On the other hand, high acidity alone did not lead to any intestinal damage.
Who this helps: This research is beneficial for doctors and healthcare providers treating newborns with respiratory issues.
