Cirugía colorrectal laparoscópica mano asistida: experiencia con una técnica original

INTRODUCTION: Hand-assisted laparoscopic colorectal surgery (HALS) is an alternative to straight laparoscopic approach (SL) that requires the use of a specific device to maintain the pneumoperitoneum. Our group has described an original double glove technique to replace it. Our purpose was to compare perioperative outcomes of patients undergoing HALS using this original technique vs SL. METHODS: Retrospective review of a prospective database including patients who underwent elective laparoscopic colorectal resections between 2004 to 2020 at the Hospital Italiano, Argentina. Logistic regression analysis, propensity score matching, and inverse probability weighting were used to estimate adjusted treatment effects for perioperative outcomes. RESULTS: HALS (n=458) and SL (n=1692) cases were demographically similar. HALS was associated with a shorter operative time (170.3 vs 206.9 minutes, p<0.001). Such difference was even more pronounced in obese (44.1 min), large patients (37.5 min), complex procedures (33.8 min) and surgeries carried out by non-trained surgeons (57,6 vs 31,6 minutes, p<0.001). Hand-assisted was associated with a lower conversion rate (5% vs 9.9%, p<0.001) with an adjusted odds ratio of 0.45 (95%CI 0.28-0.73). No difference in hospital stay, morbidity, and readmission rates was found. CONCLUSION: HALS with double-glove technique is comparable to SL in terms of postoperative outcomes keeping reduced operative time and conversion rates, especially in obese patients undergoing complex procedures.
