Gunsight suture with subcutaneous vacuum drainage during enterostomy decreased the surgical site infection rate in obese rectal cancer patients: A retrospective study
Bibliographic record
Abstract
Abstract Background Surgical site infection (SSI) is the most common complication after stoma closure and is particularly common in obese patients. To reduce the incidence of SSI, various skin closure techniques have been proposed; however, the best technique is still under debate. The purpose of this study was to explore the effectiveness of subcutaneous vacuum drains (SVDs) after two surgical suture techniques following stoma reversal in obese patients. Methods Data from 190 obese patients with rectal cancer who underwent stoma reversal for enterostomy between February 2012 and April 2023 at Jinxiang Hospital Affiliated to Jining Medical University were retrospectively analyzed. These patients were divided into two groups: gunsight suture (GS) with SVD and primary linear suture (PLS) with SVD. The GS group and PLS group included 90 and 100 patients, respectively. The clinical characteristics and short-term outcomes were compared between the two groups. Postoperative pain scores were analyzed using a generalized estimation equation. Results Surgery was successfully performed in both groups. The rate of SSI in the GS group was significantly lower than that in the PLS group (2.2% vs 9.0%, P = 0.046). Patients in the GS group had a significantly shorter wound healing time than did patients in the PLS group, as well as a significantly shorter postoperative fasting time (P < 0.05). No significant differences were found between the groups in terms of the postoperative hospital stay, operative time, and estimated blood loss (P > 0.05). The results of the generalized estimation equation analysis showed that the GS group had significantly lower pain scores at 12, 24, 48, and 72 h after surgery than the PLS group (P < 0.05). Moreover, the GS group showed significantly better alleviation of wound pain between 12 and 72 h after surgery (P < 0.05). Conclusions The GS technique with SVD may be recommended for wound closure of a nonfunctioning stoma in obese patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
