Outcome following surgery to treat septic peritonitis in 95 cats in the United Kingdom

Stapled enterectomy reduces surgical time when compared with sutured enterectomy: a retrospective review of 54 cats

OBJECTIVES

Feline enterectomy is commonly performed in referral and general veterinary practice; however, existing studies in the veterinary literature lack significant case numbers to guide clinical decision-making. In addition, no studies have evaluated the use of surgical staplers in cats for this procedure. This study aimed to compare the use of surgical staplers for functional end-to-end anastomosis (SFEEA) with hand-sewn end-to-end anastomosis (EEA) in cats. Additional aims included investigating the feasibility of surgical staplers in cats as well as assessing short- and long-term complications and outcomes.

METHODS

The medical records of four referral hospitals were retrospectively searched for cats that had undergone enterectomy between 2003 and 2022. Preoperative, intraoperative and postoperative data were compared between the SFEEA and EEA groups, with a median long-term follow-up time of 488 days (interquartile range 255-1030).

RESULTS

In total, 54 cats met the inclusion criteria for this study, with 24 undergoing an SFEEA while 30 underwent EEA. There was a significant difference in surgical time between the two groups. The SFEEA group had a mean surgical time 34.3 ± 9.274 mins faster than the EEA group (P <0.001). Unique complications reported for the SFEEA group included haemo abdomen and anastomotic stricture.

CONCLUSIONS AND RELEVANCE

SFEEA should be considered in cats where anaesthetic time should be kept as short as possible, such as patients with American Society of Anesthesiologists scores of 3-4. Stricture at the anastomotic site may be seen in the long term for cats undergoing SFEEA.

Association of the origin of contamination and species of microorganisms with short-term survival in dogs with septic peritonitis

OBJECTIVE

To assess the association between anatomical location of contamination and mortality in dogs with gastrointestinal and biliary origin of septic peritonitis.

METHODS

Medical records at two private referral hospitals between 2003 and 2020 were retrospectively reviewed. Cases were included if the origin of contamination was confirmed intraoperatively within the gastrointestinal or biliary tract. Cases were excluded if the dog died or was euthanized intraoperatively or where the data regarding the origin of contamination were not available. The association of anatomical origin with survival was assessed specifying the locations as stomach, small intestine, large intestine and biliary tract. The gastrointestinal tract origin was further subdivided into pylorus, nonpylorus, duodenum, jejunum, ileum, caecum and colon.

RESULTS

The overall survival rate was 75.9% (n = 44/58). There were no significant differences in survival among different anatomical origins of contaminations before or after subdivision (P = 0.349 and 0.832, respectively). Also, there was no association between isolated microorganism species in microbiological culture and the anatomical origin (P = 0.951) and the microorganism species was not associated with survival (P = 0.674).

CONCLUSIONS

There was no association between anatomical location of leakage, microorganism species and survival although further studies are warranted to analyse the relationships between anatomical leakage site and microorganism species as well as microorganism species and mortality.

СRITERIA FOR ASSESSING ENDOGENOUS INTOXICATION IN PATIENTS WITH MULTIPLE PERITONITIS

OBJECTIVE

The aim: To determine the diagnostic significance of the level of malondialdehyde (MDA) in various biological media for RP for assessing and predicting the course of the disease.

PATIENTS AND METHODS

Materials and methods: Our study included The work was based on the results of surgical treatment of 60 patients with RP: according to MPI I - in 17 (28.3%), MPI II - in 23 (38.4%) and MPI III - in 20 (33.3%) patients. Surgical intervention for RP was aimed at sanitation and drainage of the abdominal cavity. The control group included 15 practi¬cally healthy people, whose blood and urine biochemical parameters served as the norm. According to the clinical course of the disease, the patients were divided depend on admission, The secondary product of lipid peroxidation - MDA was studied in blood serum, peritoneal exudate and urine in patients with RP, depending on the severity of the pathological process according to the Mannheim peritoneal index (MPI) - I severity (I), II severity (II), III severity (III). The work was based on the results of surgical treatment of 60 patients with RP: according to MPI I - in 17 (28.3%), MPI II - in 23 (38.4%) and MPI III - in 20 (33.3%) patients.

RESULTS

Results: Analyses of results showed that the average value of MDA in various biomedicals of recovered (n = 18) and subsequently died (n = 5) patients with MPI II are given in Table. 2. As can be seen from the presented data, the average value of MDA in blood serum and peritoneal exudate in patients with a lethal outcome is significantly higher than in those who have recovered. This fact indicates a more pronounced endogenous intoxication in patients who died from RP.

CONCLUSION

Conclusions: The content of MDA in the blood serum before surgery in patients with a lethal outcome was 190% (p <0.001). The level of MDA in urine in patients according to MPI II who subsequently died before surgery was 110% (p <0.001), and in those who recovered by 300% (p <0.001) it was higher than the norm. exudate taken during the operation averaged 4.14 ± 0.33 nmol / ml, then in the recovered - 2.89 ± 0.08 nmol / ml. A high level of MDA in the blood serum, peritoneal exudate with a decrease in the elimination of MDA in the urine in the postoperative period are prognostically unfavorable signs in patients, indicating the continuation of endogenous intoxication and a possible death.
