RESUMEN
BACKGROUND: The efficacy of pelvic floor peritoneum closure (PC) during endoscopic low anterior resection (E-LAR) of rectal cancer remains unclear. This study aimed to clarify whether pelvic floor PC affected short-term outcomes. METHODS: The study group comprised patients with the pathologically confirmed diagnosis of rectal cancer who underwent E-LAR with pelvic floor PC or with no PC (NPC) between January 2013 and December 2018 in Southwest Hospital. After propensity score matching (PSM), 584 patients (292 who underwent PC and 292 who underwent NPC) were evaluated. Postoperative indicators, including the rates of complications, anastomotic leakage (AL), reoperation, and inflammation, were observed in the two groups. RESULTS: No significant difference was observed in the rates of postoperative complications between the PC and NPC groups. The rates of AL were similar (11.3% vs. 9.2%, p = .414). However, the reoperation rate of patients in the PC group was significantly lower than that of patients in the NPC group after AL (36.4% vs. 11.1%, p = .025). The hospital costs were higher in the NPC leakage subgroup (p = .001). Additionally, the serum C-reactive protein levels were lower in the PC group on postoperative days (PODs) 1, 3, and 5, whereas procalcitonin levels on POD 1 and 3 were lower in the PC group but did not differ significantly on POD 5. CONCLUSION: Pelvic peritonization did not affect the rate of complications, especially AL; however, it effectively reduced the reoperation and inflammation rates and reduced hospitalization costs. Other short-term outcomes were similar, which warrant the increased use of pelvic peritonization in endoscopic surgery.

Purpose: The objective of this study was to explore the risk factors for anorectal dysfunction after intersphincteric resection in patients with low rectal cancer. Methods: A total of 251 patients who underwent intersphincteric resection from July 2014 to June 2020 were included in this study, for which the Kirwan's grade, Wexner score, and anorectal manometric index were used to evaluate the anorectal function and other parameters including demographics, surgical features, and clinical and pathological characteristics. These parameters were analysed to explore the potential risk factors for anorectal function after intersphincteric resection. Results: In the 251 included patients, 98 patients underwent partial intersphincteric resection, 87 patients underwent subtotal intersphincteric resection, and 66 patients underwent total intersphincteric resection. There were 53 (21.1%) patients who had postoperative complications, while no significant difference was observed between the three groups. Furthermore, 30 patients (45.5%) in the total intersphincteric resection group were classified as having anorectal dysfunction (Kirwan's grade 3-5), which was significantly higher than that in the partial intersphincteric resection group (27.6%) and subtotal intersphincteric resection group (29.9%). The mean Wexner score of patients that underwent total intersphincteric resection was 7.9, which was higher than that of patients that had partial intersphincteric resection (5.9, p = 0.002) and subtotal intersphincteric resection (6.4, p = 0.027). The initial perceived volume was lower in the total intersphincteric resection group than in the partial and subtotal intersphincteric resection groups at 1, 3, and 6 months after intersphincteric resection. In addition, the resting pressure, maximum squeeze pressure, and maximum tolerated volume in the total intersphincteric resection group were worse than those in the partial and subtotal groups at 3 and 6 months after intersphincteric resection. Univariate and multivariate analyses suggested that an age ≥65, total intersphincteric resection, and preoperative chemoradiotherapy were independent risk factors for anorectal dysfunction (P = 0.023, P = 0.003, and P = 0.008, respectively). Among the 66 patients who underwent total intersphincteric resection, 17 patients received preoperative chemoradiotherapy, of which 12 patients (70.6%) were classified as having anorectal dysfunction. Conclusion: The current study concluded that age ≥65, total intersphincteric resection, and preoperative chemoradiotherapy were risk factors for anorectal dysfunction after intersphincteric resection. The morbidity of anorectal dysfunction after total intersphincteric resection for patients who received preoperative chemoradiotherapy was relatively high, and the indication should be carefully evaluated.
RESUMEN
Purpose: To evaluate the effectiveness of the comprehensive post-operative management including low-frequency endo-anal electrical stimulation and daily suppository usage on post-operative anal functional recovery for low rectal cancer patients who underwent robotic total intersphincteric resection (ISR). Methods: A retrospective analysis was performed on 42 low rectal cancer patients who underwent robotic total ISR, of which 23 patients received comprehensive post-operative management, including biofeedback low-frequency endo-anal electrical stimulation and daily suppository usage (management group). Wexner score and anorectal manometric values, including resting pressure (RP), maximum squeeze pressure (MSP), initial perceived volume (IPV), and maximum tolerated volume (MTV), were assessed and compared. Results: A total of 42 low rectal cancer patients were included in our study. The RP at 6 months after ISR (40.95 ± 6.95 mmHg vs. 33.29 ± 5.40 mmHg, p = 0.002) and MSP at 3 and 6 months after ISR (72.05 ± 10.16 mmHg vs. 69.05 ± 8.67 mmHg, p = 0.031; 91.57 ± 15.47 mmHg vs. 84.05 ± 12.94 mmHg, p = 0.039, respectively) were significantly higher in the management group. The median IPV at 1 and 3 months after ISR (17.81 ± 3.61 ml vs. 15.43 ± 5.08 ml, p = 0.038; 20.19 ± 4.35 ml vs. 17.67 ± 5.16 ml, p = 0.044, respectively) and MTV at 3 months after ISR (83.71 ± 5.44 ml vs. 76.10 ± 8.42 ml, p = 0.012) were significantly higher in the management group. Wexner scores at 1 and 3 months after closure of stoma (COS) in the management group were significantly lower (11.3 ± 2.9 vs. 13.4 ± 3.0, p = 0.041; 8.9 ± 2.0 vs. 10.6 ± 2.4, p = 0.036, respectively). Conclusions: Comprehensive post-operative management could accelerate the recovery of sphincteric function and anal sensitivity after robotic total ISR and could also contribute to treatment of fecal incontinence followed by COS.
RESUMEN
OBJECTIVES: To explore the risk factors for relapse of hyperglycemia in obese patients with type II diabetes mellitus (T2DM) who received laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery. METHODS: A retrospective analysis was performed on all obese patients with T2DM who underwent a LRYGB during the period 2011-2013. Demographics, preoperative body mass index (BMI), preoperative glycated hemoglobin A1c (HbA1c), adherence to lifestyle intervention, preoperative medication of insulin, and the time interval between surgery and diagnosis of T2DM were investigated and compared. RESULTS: A total of 24 patients were included in our study. The median age was 45.5 years, the median BMI was 29.9 kg/m2, and the median HbA1c was 7.9%. Out of 24 patients, 54.2% (13/24) experienced a relapse of hyperglycemia. The 1-year, 3-year, and 5-year relapse rates were 4.2%, 12.5%, and 50.0%, respectively. The preoperative HbA1c level, C-peptide (2 h) level, and C-peptide (3 h) level were identified as independent variables for the relapse of hyperglycemia (8.11 ± 0.48 vs 7.72 ± 0.37 kg/m2, p = 0.036; 4.35 ± 1.46 vs 7.13 ± 4.10 ng/ml, p = 0.032; 3.76 ± 0.61 vs 5.99 ± 3.39 ng/ml, p = 0.029). Lifestyle intervention could reduce the hyperglycemia relapse rate (66.7 vs 41.7%) after LRYGB surgery. CONCLUSIONS: The preoperative HbA1c level and C-peptide level at surgery have an important significance in predicting the relapse of hyperglycemia after LRYGB surgery; lifestyle intervention is crucial for these patients.

BACKGROUND: ED was once and is still commonly applied to prevent mainly EH and subgaleal CSF collection. We designed this study to observe if ED could decrease the incidence and volume of EH and subgaleal CSF collection after supratentorial craniotomy in epileptic patients. METHODS: Three hundred forty-two epileptic patients were divided into 2 groups according to their first craniotomy date (group 1 in odd date and group 2 in even date). Patients in group 1 had ED and those in group 2 had no ED. The patient numbers and volumes of EH and subgaleal CSF collections in both groups were recorded and statistically analyzed. RESULTS: There were 22 EHs in group 1 and 20 EHs in group 2. There were 11 and 10 subgaleal CSF collections in groups 1 and 2, respectively. The average volume of EH was 13.5 +/- 8.12 and 14.65 +/- 7.72 mL in groups 1 and 2, respectively. The average volume of subgaleal CSF collection was 42.76 +/- 12.09 and 43.75 +/- 11.44 mL in groups 1 and 2, respectively. There were no statistical differences in the incidence and average volume of EH and subgaleal CSF collection between the 2 groups. CONCLUSIONS: ED cannot decrease the incidence and volume of EH and subgaleal CSF collection. ED should not be recommended after supratentorial epileptic craniotomy.
