Predisposing factors for high output stoma in patients with a diverting loop ileostomy after colorectal surgeries

Purpose@#One of the most common ileostomy-related complications is high output stoma (HOS) which causes significant fluids and electrolytes disturbances. We aimed to analyze the incidence, severity, and risk factors for readmission for HOS. @*Methods@#We reviewed all patients who underwent loop ileostomy closure in a single institution between 2010 and 2020. Patients that were readmitted for dehydration due to HOS during the time interval between the creation and the closure of the stoma were identified and divided into a study (HOS) group. The remaining patients constructed the control group. @*Results@#A total of 307 patients were included in this study, out of which, 41 patients were readmitted 73 times (23.7% readmission rate) for the HOS group, and the remaining 266 patients constructed the control group. Multivariate analysis identified; advanced American Society of Anesthesiologists (ASA) physical status (PS) classification, elevated baseline creatinine, and open surgery as risk factors for HOS. Renal function worsened among the entire cohort between the construction of the stoma to its closure (mean creatinine of 0.82 vs. 0.96, P<0.0001). @*Conclusion@#Loop ileostomy formation is associated with a substantial readmission rate for dehydration as a result of HOS, and increasing the risk for renal impairment during the duration of the diversion. We identified advanced ASA PS classification, open surgery, and elevated baseline creatinine as predictors for HOS.

Learning curve of robotic inguinal hernia repair in the hands of an experienced laparoscopic surgeon: a comparative study.

BACKGROUND: Since its introduction, robotic surgery has been utilized in different types of surgeries over various specialties. However, studies done thus far comparing robotic (Rob. IHR) and laparoscopic inguinal hernia repair (Lap. IHR) yielded contrasting results. OBJECTIVES: This study evaluates the outcomes of adapting the robotic platform for IHR by a single experienced surgeon, comparing it to laparoscopic inguinal hernia repair (Lap. IHR) performed at same time period. METHODS: Retrospective analysis of a prospectively maintained database including all patients that underwent IHR between 2017 and 2019 (n = 188) was performed. Analyzed data included patient demographics, hernia characteristics, intraoperative data and postoperative outcomes. RESULTS: Patients (n = 188) underwent a total of 120 Rob. IHR and 157 Lap. IHR. Age, sex, BMI, ASA score and length of hospital stay were similar in both groups. Recurring hernias were repaired more often robotically (p = 0.001). Operative time was significantly longer using the robot. (78.8 ± 24 min vs 55.4 ± 17.4 min for unilateral) and (107.9 ± 30 min vs 62.6 ± 20.2 min for bilateral) Rob. IHR vs Lap. IHR respectively, p < 0.001. Rob. IHR operative time decreased while building a learning curve. Rates of simple and severe postoperative complications were similar, p = 0.414. Recurrence occurred once in Rob. IHR group (1.4%) and 3 times in the Lap. IHR (1.9%) (p = 0.642). CONCLUSION: Our series shows that Rob. IHR is safe with comparable outcomes to Lap. IHR even in early learning curve. Robotic inguinal hernia repair allows the buildup of a short, safe and efficacious robotic learning experience for the minimally invasive surgeons for future more complex robotic surgeries.

Transabdominal Preperitoneal (TAPP) for the Treatment of Spigelian hernias.

BACKGROUND AND OBJECTIVES: Spigelian hernias (SH) are a rare variant of abdominal wall defects that require prompt surgical intervention. With the advancement of abdominal wall surgery capabilities, there are several possible approaches of repairing SH. The aim of the study was to present our experience in performing laparoscopic or robotic transabdominal preperitoneal (TAPP) repairs of SH and discuss the advantages of TAPP in such hernias. METHODS: Retrospective review of a prospectively maintained database of SH TAPP repairs between February 1, 2015 and February 29, 2020. Data included clinical details, size and location of fascial defect, presence of concomitant hernias, surgery duration, length of stay (LOS), mesh type, mesh size, and fixation method. Follow up visits at 1 month postoperative and telephone survey for pain assessment and subsequent hernia-related treatment. RESULTS: During the study period 16 patients underwent TAPP SH repairs, 13 laparoscopically and 3 robotic. Seven (44%) patients had a concomitant inguinal hernia with 1 patient having bilateral inguinal defects. Mean surgery duration and mean LOS were 78 (range 41 - 120) minutes & 1.6 (range 1 - 3) days, respectively. Immediate postoperative complications included 2 seromas and 1 port-site hematoma. Mean telephone survey follow up was 17 months (range 3 - 49). Mean visual analogue scale scores were significantly lower at follow-up compared to discharge (1.9 vs 0.5, P = 0.0015). CONCLUSION: Advantages of TAPP SH repair include low postoperative chronic pain, potential low wound complications, intra-abdominal visualization of hernia contents, and repairing of concomitant inguinal hernias simultaneously.
