RESUMO
Robot-assisted Heller myotomy (RAHM) is an increasingly popular alternative to the traditional laparoscopic Heller myotomy (LHM) in the surgical management of achalasia, with similar outcomes and potentially lower complication rates. We aimed to systematically review the literature by comparing the technical success, outcomes, and complications of RAHM and LHM. We searched PubMed, Medline, and Cochrane Central Register for articles published between 2001 and 2023. Data on technical success, clinical outcomes, length of hospital stay, esophageal perforation rate, and overall mortality were extracted. A total of 11 articles were included in the study, comparing a total of 3,543 RAHM and 15,434 LHM cases. The mean operative time was significantly higher in the RAHM procedure with a total mean difference of 23.95 (95% confidence interval (Cl) 17.09, 30.81; p < 0.00001; I2 = 99%). However, the RAHM was associated with a significantly shorter hospital stay, with a total mean difference of -0.24 (95% Cl = -0.40, -0.08; p < 0.00001; I2 = 81%). The volume of blood loss was significantly smaller in RAHM with a total mean difference of -61.11 (95% CI = -150.31, 28.09; p < 0.00001; I2 = 99%). Esophageal mucosal perforation was significantly lower in RAHM with an odds ratio of 0.36 (95% CI = 0.16, 0.82; p = 0.02; I2 = 22%). Both procedures were associated with similar rates of symptom relief. Although no mortality was recorded in patients who underwent RAHM as opposed to 16 cases in patients who underwent LHM, no statistically significant difference could be reached. Our results demonstrate that while both procedures yield comparable clinical outcomes, RAHM is associated with a lower overall complication rate, particularly a lower rate of esophageal mucosal perforation, shorter hospital stay, and possibly a lower mortality rate. This confirms that RAHM is a viable and justifiable alternative to the conventional LHM in the surgical management of achalasia.
RESUMO
Laparoscopic sleeve gastrectomy (LSG) is the most widely performed bariatric surgery and has been associated with excellent outcomes and a significant reduction in obesity-related morbidity and mortality. Traditionally, this surgery is performed using five to seven trocars. However, LSG performed through a single trocar is emerging as a less invasive method of performing this surgery. This systematic review and meta-analysis compare the outcomes and complication rates of single-port versus multi-port LSG. We searched PubMed, Medline, Scopus, and the Cochrane Library for articles published from 2008 to 2023, in accordance with the PRISMA 2020 guidelines. Data on variables such as operative time, excess weight loss, intraoperative bleeding, postoperative leak, and incisional hernia rates were collected and analyzed using a random-effects model. Fourteen articles met the inclusion criteria and were included in the meta-analysis. No significant differences were found between the single-port LSG (SILSG) and conventional LSG (CLSG) groups in terms of operative time, rate, intraoperative complications, length of hospital stay, postoperative complications, and excess weight loss (EWL). Furthermore, single incision sleeve gastrectomy showed better satisfaction with the cosmetic score. SILSG is a viable alternative procedure, showing comparable outcomes to multiport conventional sleeve gastrectomy, in addition, to a better cosmetic satisfaction score.
RESUMO
The purpose is to delineate the clinico-pathologic features of papillary thyroid carcinoma (PTC) occurring in a background of Hashimoto's thyroiditis (HT). A retrospective analysis of consecutive PTC patients who underwent surgery at an academic center between Jan. 2010 and Jan. 2020 was performed. The primary end point was to assess whether a background of HT implied a higher likelihood for postoperatively determined high-risk histopathologic features. Accordingly, its implication on initial surgical planning. Tumor high-risk features included aggressive histologic variants, lymphovascular invasion, extrathyroidal extension, multifocality, and positive nodal metastasis. To achieve the primary outcome of interest, a two group-designation was followed: group A (none-HT-group) and group B (HT-group). The two groups were also compared regarding postoperative complications as a secondary outcome of interest. In the specified period, 331 patients were found to have a histologically proven diagnosis of PTC. Group A accounted for 80% (265/331) of the study cohort, while group B accounted for the remainder 20%. PTC was significantly more prevalent in the absence of HT (p < 0.0001). Both groups were comparable in mean-patient-age. However, Group B demonstrated a considerably higher male:female ratio (1:10 vs. 1:3; p = 0.01). All postoperatively determined high-risk histopathologic features were comparable in both groups (p > 0.05). Nevertheless, transient hypoparathyroidism was considerably higher in group B (12% vs. 23%; p = 0.02). A background of HT does not seem to reflect a more aggressive cancerous biologic behavior. Therefore, it should not preclude the conservative surgical strategy adopted by the most recent clinical practice guidelines.
