Key result
Preoperative severe malnutrition linked to a ~447% increase in postoperative complications after abdominal surgery.
Why the study?
There was limited literature analyzing malnutrition among patients subjected to gastrointestinal surgeries.
Does preoperative nutritional status predict postoperative complications in patients undergoing abdominal surgery?
Observational (n=225)
No
Does preoperative nutritional status predict postoperative complications in patients undergoing abdominal surgery?
Simple bedside nutritional assessment tools like serum albumin, absolute lymphocyte count, and SGA can accurately identify malnourished patients preoperatively and are good predictors of postoperative complications in abdominal surgery.
Answers are grounded in this paper and cite their sources.
Severe malnutrition was associated with higher abdominal surgery complications; leaves open whether preoperative optimization reduces risk.
analysis of the data, ALC, serum albumin, and SGA correlate with the postoperative complication rate with a p-value <0.05 as significant. On the contrary, BMI, MAC, and TSFT did not correlate with postoperative complications. Conclusion Preoperative malnutrition is common among patients undergoing abdominal surgeries in the urban private health care sector. Although there have been studies that have analyzed the incidence of malnutrition in patients undergoing oncological surgeries, there is limited literature on malnutrition among patients subjected to gastrointestinal surgeries. We conclude that simple bedside nutritional assessment tools like serum albumin, absolute lymphocyte count, and SGA can accurately identify malnourished patients preoperatively and are good predictors of postoperative complications. Hence, it is imperative to assess and attempt to improve the nutritional status of the patients preoperatively.

Akula et al. (2021) conducted an observational in Gastrointestinal surgery (n=225). Preoperative malnutrition vs. Well-nourished status was evaluated on Postoperative complications (OR 5.467, p=9.03E-06). Preoperative severe malnutrition significantly increased the rate of postoperative complications to 63.38% compared to 26.62% in well-nourished patients undergoing abdominal surgery.
