RESUMO

BACKGROUND: Patients with compromised appendix base constitute a subgroup of patients with complicated appendicitis, and there is few available information. OBJECTIVE: To study the frequency of stump leaks and fistulae in patients with complicated appendicitis with compromised stump. METHOD: This is an observational, retrospective study of patients that underwent laparoscopic appendectomy with compromised appendix stump. RESULTS: From 2015 to 2019, 158 patients with complicated appendicitis were operated, of them 54 had compromised base or stump. There were 66.7% men, with a mean age of 38.7 years. For stump closure, a simple knot was employed in 57.4%, and in 42.6% an invaginated suture was employed. Regarding complications, 16.7% developed intraabdominal abscess, 7.4% ileus and 7.4% had wound infection. We found one stump leak and one stump fistula. The mean length of stay was 5.4 days (range: 1-20). There were 5 reoperations, 4 for abscess drainage and 1 for stump leak. CONCLUSIONS: Patients with acute complicated appendicitis with compromised appendicular base, laparoscopic surgery either with simple knot or with invaginated suture resulted in low frequency of stump leaks and fistula.

ANTECEDENTES: Los pacientes con base apendicular comprometida constituyen un subgrupo de pacientes con apendicitis complicada y existe poca información al respecto. OBJETIVO: Conocer la frecuencia de fístulas y fugas fecales en pacientes con apendicitis complicada con base apendicular comprometida. MÉTODO: Se trata de un estudio observacional, retrospectivo y transversal de pacientes operados de apendicectomía laparoscópica con base apendicular comprometida. RESULTADOS: De 2015 a 2019 se encontraron 158 casos de apendicitis complicada, de los cuales 54 tenían la base apendicular comprometida. Hubo predominio de varones (66.7%) y la edad media fue de 38.7 años. En el 57.4% de los casos se realizó un nudo simple y en el 42.6% un punto transfictivo con invaginación del muñón. En relación con las complicaciones, el 16.7% desarrollaron abscesos intraabdominales, el 7.4% íleo y el 7.4% infección de herida. Hubo un paciente con fuga del muñón y un paciente con fístula cecal. El tiempo medio de estancia hospitalaria fue de 5.4 días (rango: 1-20). Se realizaron cinco reintervenciones: cuatro para drenaje de absceso intraabdominal y una por fuga del muñón. CONCLUSIONES: En los pacientes con base apendicular comprometida, el manejo laparoscópico con ligadura simple o con punto transfictivo resulta en una baja frecuencia de fuga y fístula del muñón apendicular.

RESUMO

BACKGROUND: The Da Vinci Robotic Surgical System has positioned itself as a tool that improves the ergonomics of the surgeon, facilitating dissection in confined spaces and enhancing the surgeon's skills. The technical aspects for successful bile duct repair are well-vascularized ducts, tension-free anastomosis, and complete drainage of hepatic segments, and all are achievable with robotic-assisted approach. METHODS: This was a retrospective study of our prospectively collected database of patients with iatrogenic bile duct injury who underwent robotic-assisted Roux-en-Y hepaticojejunostomy. Pre-, intra-, and short-term postoperative data were analyzed. RESULTS: A total of 30 consecutive patients were included. The median age was 46.5 years and 76.7% were female. Neo-confluences with section of hepatic segment IV were performed in 7 patients (those classified as Strasberg E4). In the remaining 23, a Hepp-Couinaud anastomosis was built. There were no intraoperative complications, the median estimated blood loss was 100 mL, and the median operative time was 245 min. No conversion was needed. The median length of stay was 6 days and the median length of follow-up was 8 months. The overall morbidity rate was 23.3%. Two patients presented hepaticojejunostomy leak. No mortality was registered. CONCLUSION: Robotic surgery is feasible and can be safely performed, with acceptable short-term results, in bile duct injury repair providing the advantages of minimally invasive surgery. Further studies with larger number of cases and longer follow-up are needed to establish the role of robotic assisted approaches in the reconstruction of BDI.

RESUMO

Spontaneous biliary-enteric fistula after laparoscopic cholecystectomy bile duct injury is an extremely rare entity. Y-en-Roux hepaticojejunostomy has been demonstrated to be an effective surgical technique to repair iatrogenic bile duct injuries. Seven consecutive patients underwent robotic-assisted (n = 5) and laparoscopic (n = 2) biliary-enteric fistula resection and bile duct repair at our hospital from January 2012 to May 2017. We reported our technique and described post-procedural outcomes. The mean age was 52.4 years, mostly females (n = 5). The mean operative time was 240 min for laparoscopic cases and 322 min for robotic surgery, and the mean estimated blood loss was 300 mL for laparoscopic and 204 mL for robotic cases. In both groups, oral feeding was resumed between day 2 or 3 and hospital length of stay was 4-8 days. Immediate postoperative outcomes were uneventful in all patients. With a median of 9 months of follow-up (3-52 months), no patients developed anastomosis-related complications. We observed in this series an adequate identification and dissection of the fistulous biliary-enteric tract, a safe closure of the fistulous orifice in the gastrointestinal tract and a successful bile duct repair, providing the benefits of minimally invasive surgery.

RESUMO

BACKGROUND: Laparoscopic cholecystectomy (LC) is the treatment of choice for mild and moderate acute cholecystitis. The aim of this study was to analyze the utility of C-reactive protein (CRP) as a predictor of difficult laparoscopic cholecystectomy (DLC) in patients with acute cholecystitis. MATERIALS AND METHODS: We conducted a prospective study. All patients included were treated with emergency LC. Patients were analyzed as DLC and nondifficult laparoscopic cholecystectomy (NDLC). Multiple logistic regression and receiver-operating characteristic curve analysis were employed to explore which variables were statistically significant in predicting a DLC. Two different models were analyzed. RESULTS: A total of 66 patients were included (37.9% DLC versus 62.1% NDLC). Ideal cutoff point for CRP was calculated as 11 mg/dL, with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for predicting DLC being 92% (95% CI 75-97.8), 82.9% (95% CI 68.7-91.5), 76.7%, and 94.4%, respectively. In the first model multivariate analysis, age >45 years, male sex, gallbladder wall thickness ≥5 mm, and pericholecystic fluid collection were significant predictors of DLC, with an area under the curve (AUC) of 0.89. In the second model multivariate analysis, only CRP ≥11 (odds ratio, OR = 17.9, P = .013) was significant predictor of presenting DLC, with an AUC of 0.96. CONCLUSIONS: Preoperative CRP with values ≥11 mg/dL was associated with the highest odds (OR = 17.9) of presenting DLC in our study. This value possesses good sensitivity, specificity, PPV, and NPV for predicting DLC in our population with acute calculous cholecystitis.
