Switching from robotic-assisted extended transabdominal preperitoneal (eTAPP) to totally extraperitoneal (eTEP) hernia repair for umbilical and epigastric hernias.

Our study aimed to assess the safety and effectiveness of the robotic-assisted extended totally extraperitoneal (eTEP) repair compared to transabdominal preperitoneal (eTAPP) repair with a suprapubic trocar insertion to treat umbilical and epigastric hernias. On a prospectively maintained database, we identified patients who underwent either eTEP or eTAPP for treating umbilical and epigastric hernias. During the study period, 53 patients were included, 32 in the eTEP group and 21 in the eTAPP group. The mean age was 59.0 ± 13.9 years, 45 patients (84.9%) were male, and the mean BMI was 28.0 ± 5.9 kg/m2. Most hernias were umbilical (81.1%) and primary (83.0%). The operative time for eTEP was slightly shorter than for eTAPP (106 ± 43 min vs. 126 ± 74 min, p = 0.232). Postoperatively, only one case of bleeding and one seroma were recorded. No complication occurred during a mean follow-up of 11.3 ± 6.4 months in the eTEP group and 20.5 ± 9.7 months in the eTAPP group. In conclusion, our study showed that the eTEP with suprapubic approach was safe and feasible in the treatment of epigastric and umbilical hernias. According to our experience, shorter operative time, integrity of the posterior layers and increased overlap size are the main surgical reasons of switching from eTAPP to eTEP.

Laparoscopic vs. ultrasound-guided transversus abdominis plane (TAP) block in colorectal surgery: a systematic review and meta-analysis of randomized trials.

BACKGROUND: The transversus abdominis plane block (TAPB) is effective for postoperative pain management in patients undergoing colorectal surgery. However, evidence regarding the optimal delivery method, either laparoscopic (L-TAPB) or ultrasound-guided (U-TAPB) is lacking. Our study aimed to compare the effectiveness of these delivery methods. METHODS: We carried out a literature search of PubMed, Cochrane Library, Web of Science, and Google Scholar databases to include randomized studies comparing patients receiving either L-TAPB or U-TAPB during minimally invasive colorectal surgery. The primary endpoint was opioid consumption in the first 24 h after surgery. Risk of bias was assessed with the RoB-2 tool. Effect size was estimated for each study with 95% confidence interval and overall effect measure was estimated with a random effect model. RESULTS: The literature search revealed 294 articles, of which four randomized trials were eligible. A total of 359 patients were included, 176 received a L-TAPB and 183 received a U-TAPB. We established the non-inferiority of L-TAPB, as the absolute difference of - 2.6 morphine-mg (95%CI - 8.3 to 3.0) was below the pooled non-inferiority threshold of 8.1 morphine-mg (low certainty level). No difference in opioid consumption was noted at 2, 6, 12, and 48 h (low to very low certainty level). Postoperative pain, nausea and vomiting were similar between groups at different timepoints (low to very low certainty level). No TAPB-related complications were recorded. Finally, the length of hospital stay was similar between groups. CONCLUSION: For postoperative multimodal analgesia both L-TAPB and U-TAPB may result in little to no difference in outcome in patients undergoing colorectal surgery.

Intestinal ischemia due to internal hernia beneath the right external iliac artery after laparoscopic hysterectomy and lymphadenectomy: A case report.

INTRODUCTION AND IMPORTANCE: The occurrence of an internal hernia beneath the external iliac artery is rare but may occur after pelvic lymphadenectomy. The challenging treatment of this rare condition should be tailored to the patient's clinical and anatomical characteristics. CASE PRESENTATION: We present the case of a 77-year-old woman with previous history of laparoscopic hysterectomy and adnexectomy with extended pelvic lymphadenectomy for endometrial cancer. The patient was admitted in the emergency department because of severe abdominal pain and a computed tomography scan showed signs of internal hernia. The laparoscopy confirmed such a finding below the right external iliac artery. A small bowel resection was deemed necessary and the defect was closed with an absorbable mesh. The post-operative course was uneventful. CLINICAL DISCUSSION: Internal hernia beneath the iliac artery is a rare condition after pelvic lymphadenectomy. The first challenge is the hernia reduction, which can be safely carried out laparoscopically. Secondly, a patch or a mesh should be used to close the defect if a primary peritoneal suture is not feasible, but it requires to be fixed in the small pelvis. The use of absorbable material is a valuable option and should leave a fibrotic area that covers the hernia defect. CONCLUSION: A strangulated internal hernia beneath the external iliac artery is a possible complication after extensive pelvic lymph node dissection. The laparoscopic approach to treat bowel ischemia and to close the peritoneal defect with a mesh, should reduce as much as possible the risk of internal hernia recurrence.

Tracking the outcomes of surgical treatment of Stage 2 and 3 empyema: introduction and consolidation of minimally invasive approach.

BACKGROUND: We described the results of surgical treatment of empyema, tracing outcomes throughout the passage from the open thoracotomy (OT) approach to video-assisted thoracoscopic surgery (VATS) in a single institute. METHODS: We retrospectively analyzed the records of 88 consecutive patients treated for Stage 2 and 3 empyema (2010-2019). We divided the study period into three groups: OT period (2010-2013), early VATS (2014-2017, from the introduction of VATS program, until acme of learning curve), and late VATS (2018-2019). Groups were compared to investigate the outcomes evolution. RESULTS: Most relevant findings of the study were significant variation in postoperative length of stay (median [interquartile range]: 9 days [7.5-10], 10 [7.5-17.5], and 7 [5-10] for OT period, early VATS, and late VATS, respectively, p = 0.005), hospital admission referral to thoracic surgery interval (7.5 days [4.5-11], 6.5 [3-9], and 2.5 [1.5-5.5], p = 0.003), chest tube duration (5.5 days [5-7.5], 6 [4-6], 4 [3-5], p = 0.003), and proportion of operation performed by residents (3 [15%], 6 [16.7%], 14 [43.6%], p = 0.01). CONCLUSIONS: Our findings pictured the trajectory evolution of outcomes during introduction and consolidation of VATS treatment of empyema. During the early phase, we observed a decline in some indicators that improved significantly in the late VATS period. After a learning curve, all outcomes showed better results and we entered into a teaching phase.

Suture and Fixation of the Transversalis Fascia during Robotic-Assisted Transabdominal Preperitoneal Hernia Repair to Prevent Seroma Formation after Direct Inguinal Hernia Repair.

Background. Seroma formation after videoendoscopic repair of inguinal hernias, known as "pseudorecurrence", may vary from an asymptomatic, self-limiting occurrence to a painful, chronic problem. The aim of this study was to investigate the incidence of postoperative seroma in robotic-assisted transabdominal preperitoneal hernia repair (R-TAPP), modified by suturing and fixating the transversalis fascia to the Cooper ligament. Methods. The study was approved by the local ethics committee (2019-01132 CE-3495). Patients undergoing R-TAPP for direct inguinal hernia from October 2017 to December 2019 were included. In all patients, a barbed running suture of the transversalis fascia was performed to close the cavity resulting from the direct hernia reduction and to fix it to the Cooper ligament, then a lightweight mesh was placed. Demographic and clinical data were collected and analysed. Results. Over the study period, 67 R-TAPP in 51 patients were identified. All patients were male, with a mean age of 63.1 ± 12.7 years. There was 1 case of conversion to open surgery due to adhesions of the caecum to the groin as a result of perforated appendicitis. The mean length of the hospital stay was 1.8 ± .6 days. After discharge, no cases of seroma or recurrence at 30 days nor chronic pain at a mean follow-up of 10.3 ± 6.8 months was detected. Conclusions. In the treatment of direct inguinal hernia with R-TAPP, suturing and anchoring the transversalis fascia to the Cooper ligament are safe, feasible and recommendable in order to prevent postoperative seromas.

Learning curve of robotic-assisted transabdominal preperitoneal repair (rTAPP) for inguinal hernias.

BACKGROUND: Learning curves describe the rate of performance improvements according to the surgeon's caseload, followed by a plateau where limited additional improvements are observed. The aim of this study was to evaluate the learning curve for robotic-assisted transabdominal preperitoneal repair (rTAPP) for inguinal hernias in surgeons already experienced in laparoscopic TAPP. METHODS: The study was approved by local ethic committee. Male patients undergoing rTAPP for inguinal hernia from October 2017 to December 2019 at the Bellinzona Regional Hospital were selected from a prospective database. Demographic and clinical data, including operative time, conversion to laparoscopic or open surgery, intra- and postoperative complications were collected and analyzed. RESULTS: Over the study period, 170 rTAPP were performed by three surgeons in 132 patients, and mean age was 60.1 ± 13.7 years. The cumulative summation (CUSUM) test showed a significant operative time reduction after the 43rd operation, once the 90% proficiency on the logarithmic tendency line was achieved. The corrected operative time resulted 71.1 ± 22.0 vs. 60.8 ± 13.5 min during and after the learning curve (p = 0.011). Only one intraoperative complication occurred during the learning curve and required an orchiectomy. Postoperatively, three complications (one seroma, one hematoma, and one mesh infection) required invasive interventions during the learning curve, while no cases were recorded after it (p = 0.312). CONCLUSION: Our study shows that the rTAPP, performed by experienced laparoscopists, has a learning curve which requires 43 inguinal hernia repairs to achieve 90% proficiency and to significantly reduce the operative time.

Muzi's Tension Free Primary Closure of Pilonidal Sinus Disease: Updates on Long-Term Results on 514 Patients.

BACKGROUND: The aim of this study is to evaluate the long-term results of Muzi's tension free primary closure technique for pilonidal sinus disease (PSD), in terms of patients' discomfort and recurrence rate. METHODS: This study is a retrospective analysis of prospectively collected data. Five hundred fourteen patients were treated. Postoperative pain (assessed by a visual analog scale, VAS), complications, time needed to return to full-day activities, and recurrence rate were recorded. At 12, 22, and 54 months postoperative, patients' satisfaction was evaluated by a questionnaire scoring from 0 (not satisfied) to 12 (greatly satisfied). RESULTS: The median operative time was 30 min. The overall postoperative complication rate was 2.52%. Median VAS score was 1. The mean of resumption to normal activity was 8.1 days. At median follow-up of 49 months, recurrence rate was 0.4% (two patients). At 12 months' follow-up, the mean satisfaction score was 10.3 ± 1.7. At 22 and 54 months' follow-up, the score was confirmed. CONCLUSIONS: Muzi's tension free primary closure technique has proved to be an effective treatment, showing in the long-term follow-up low recurrence rate and high degree of patient satisfaction. Therefore, we strongly recommend this technique for the treatment of PSD.
