Symptomatic Lymphocele After Robot-Assisted Pelvic Lymphadenectomy as Part of the Primary Surgical Treatment for Cervical and Endometrial Cancer: A Retrospective Cohort Study

Pelvic lymph node dissection (PLND) is part of the primary treatment for early-stage cervical cancer and high-intermediate risk or high-risk endometrial cancer. Pelvic lymphocele is a postoperative complication of PLND and when symptomatic, lymphoceles necessitate treatment. The aim of this study was to investigate the incidence and risk factors of symptomatic lymphocele after robot-assisted laparoscopic PLND in cervical and endometrial cancer. Retrospective cohort study. Single-center academic hospital. Two hundred and fifty-eight patients with cervical cancer and one hundred and twenty-nine patients with endometrial cancer. Pelvic lymphadenectomy by robot-assisted laparoscopic surgery. We retrospectively included all patients with early-stage cervical cancer and high- intermediate risk or high-risk endometrial cancer who underwent pelvic lymphadenectomy by robot-assisted laparoscopic surgery between 2008 and 2022. Medical records were reviewed for the occurrence of a symptomatic lymphocele. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for developing a symptomatic lymphocele. In total 387 patients, 258 with cervical cancer and 129 with endometrial cancer, were included in the study. The overall incidence of symptomatic lymphoceles was 9.6% with a median follow-up of 47 months [IQR 23-61]. For the entire cohort, smoking was the only significant risk factor for symptomatic lymphoceles identified in univariate (OR 2.47, 95% CI 1.19-5.11) and multivariate analysis (OR 2.42, 95% CI 1.16-5.07). For cervical cancer, BMI (OR 1.09, 95% CI 1.00-1.17) and prior abdominal surgery (OR 2.75, 95% CI 1.22-6.17) were also identified as significant independent risk factors. For endometrial cancer, age was identified as significant independent risk factor (OR 0.90, 95% CI 0.83-0.97). This single-center cohort study demonstrated an incidence of almost 10% of symptomatic lymphoceles after robot-assisted laparoscopic PLND for cervical cancer and endometrial cancer, with a higher risk observed among patients who smoke at the time of diagnosis. Furthermore, risk factors differ between the two populations, necessitating further studies to establish risk models.

Risk factors for postoperative ileus in hysterectomy: A systematic review and meta-analysis.

The study intended to evaluate the risk factors of postoperative ileus in hysterectomy patients. Systematic review and meta-analysis. This study conducted a systematic review and meta-analysis in accordance with the Preferred Reporting Program for Systematic Review and Meta-analysis statement. PubMed, Web of Science, Embase, the Cochrane Library and China National Knowledge Internet were searched. The search period was restricted from the earliest records to March 2024. Key words used were: (hysterectomy) AND (postoperative ileus OR postoperative intestinal obstruction OR ileus OR intestinal obstruction). Two researchers screened literatures and extracted data, and used Newcastle-Ottawa scale and Joanna Briggs Institute critical appraisal checklist for analytical cross-sectional studies to evaluate their quality. Then, Stata17 software was used for statistical analysis. A total of 11 literatures were included. Personal factors and previous history of disease factors of postoperative ileus in hysterectomy patients included use opioids (OR = 3.91, 95%CI: 1.08-14.24), dysmenorrhea (OR = 2.51, 95%: 1.25-5.05), smoking (OR = 1.55, 95%: 1.18-2.02), prior abdominal or pelvic surgery (OR = 1.46, 95%CI: 1.16-1.83) and age (OR = 1.03, 95%: 1.02-1.04). Surgery-related factors included perioperative transfusion (OR = 4.50, 95%CI: 3.29-6.16), concomitant bowel surgery (OR = 3.79, 95%CI: 1.86-7.71), anesthesia technique (general anesthesia) (OR = 2.73, 95%CI: 1.60, 4.66), adhesiolysis (OR = 1.97, 95%CI: 1.52-2.56), duration of operation (OR = 1.78, 95%CI: 1.32-2.40), operation approach (laparoscopic hysterectomy) (OR = 0.43, 95%CI: 0.29-0.64) and operation approach (vaginal hysterectomy) (OR = 0.35, 95%CI: 0.18-0.69). The results of this study were personal factors and previous history of disease factors, surgery-related factors, which may increase the risk of postoperative ileus in hysterectomy patients. After the conclusion of risk factors, more accurate screening and identification of high-risk groups can be conducted and timely preventive measures can be taken to reduce the incidence of postoperative ileus. The study protocol for this meta-analysis was registered (CRD42023407167) with the PROSPERO database (www.crd.york.ac.uk/prospero).

Adhesion Band Small Bowel Obstruction in Virgin Abdomen: A Case Report

Small bowel obstruction (SBO) is a common surgical emergency, accounting for almost 50% of all emergency laparotomies with significant in-hospital morbidity. History of previous intra-abdominal surgery is very common in SBO patients, which can include up to 80% of these patients. However, there are cases of SBO with no prior abdominal surgery caused by omental bands, which are very rare and have a high probability of misdiagnosis, referred to as a virgin abdomen. In this article, a rare case of adhesion band small bowel obstruction in a virgin abdomen is presented. Although the factors related to SBO in a virgin abdomen and its underlying causes are not yet fully understood. In this case, the most possible explanation is considering the patient’s age and congenital condition because of the absence of previous abdominal surgeries or inflammation history.

Prior abdominal surgery as a potential risk factor for colonic diverticulosis or diverticulitis.

Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions and these may lead to increased intraluminal colonic pressure. To assess whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis. We analyzed data from a study of patients undergoing colonoscopy for different indications from 2020 through 2021. Patients completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking, alcohol use and co-morbidities. Three hundred and fifty-nine patients were included in the study. The mean age was 67.6 and 46% were females. Diabetes mellitus, hypertension, ischemic heart disease, chronic obstructive pulmonary disease, chronic renal failure, and body mass index were similar in the diverticulosis and control groups. The overall prevalence of colonic diverticulosis was 25% (91/359) and 48% of the patients had previous abdominal surgery. As expected, the prevalence of diverticulosis increased with age. There was no difference in the rate of previous abdominal surgery between patients with or without diverticulosis (49% vs 47%, P = 0.78). In regards to specific surgeries, inguinal hernia repair was significantly associated with diverticulosis (52% vs 20%, P = 0.001), but not diverticulitis. In contrast, appendectomy was not associated with diverticulosis (6% vs 14%, P = 0.048). These findings suggest that post-operative abdominal adhesions inducing high colonic intraluminal pressures do not appear to be the mechanism for diverticula formation. Rather, inguinal hernia and diverticulosis may share similar connective tissue pathologies with no causative relationship between them.

Transabdominal and retroperitoneal adrenalectomy: comparative study.

Laparoscopic adrenalectomy is recognized as the "gold standard" approach for benign adrenal tumors. The majority of surgeons opt for laparoscopic transabdominal adrenalectomies (LTA), while retroperitoneoscopic adrenalectomies (RPA) in the prone position have certain advantages for patients. The aim of this study was to compare the effectiveness and safety of the transabdominal and retroperitoneoscopic laparoscopic adrenalectomies. Between 2000 and 2021, our clinic performed 472 laparoscopic adrenalectomies. The age ranged from 19 to 79years, with a mean age of 50.5 ± 10.2years. The patient pool consisted of 315 women and 157 men. Tumor sizes ranged from 1 to 10cm. In a study of 316 patients undergoing LTA versus 156 with RPA, the TLA averaged 82.5min (70-98), while the RPA took 56.4min (46-62) (P < 0.001). Intraoperative blood loss was 110cc for the LTA group and 80cc for the RPA group (P < 0.05) Conversion rates stood at 2.5% for transabdominal and 4.5% for retroperitoneoscopic procedures (P = 0.254). At 24h post-operation, pain scores were 3.6 and 1.6, respectively (P < 0.001). Time to resume solid oral intake was 15.2h for TLA and 8h for RPA, with hospital stays at 4.5days and 3days respectively (P < 0.001). Short-term complications occurred in 8.9% of transabdominal and 12.2% of retroperitoneoscopic patients (P = 0.257). For small tumors, RPA offers advantages over the transabdominal method in surgery time, blood loss, post-op pain, and recovery. These benefits are enhanced for patients with prior abdominal surgeries. However, large tumors present challenges in the retroperitoneal approach due to limited space and anatomical orientation. If complications emerge, surgeons can seamlessly switch to the LTA.

Impact of Previous Open Abdominal Surgery on Open Abdominal Aortic Repair: A Study from the NSQIP Database

While endovascular aneurysm repair has become a first-line strategy in many centers, open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) is still the best option for certain patients. A significant number of patients who are offered OSR for AAA have been previously submitted to other open abdominal surgeries (PAS). It is unclear, however, how this may impact their outcomes. The purpose of this study was to determine if there is an association between PAS and outcomes of OSR of AAA. This is a retrospective cohort study based on clinical data from the American College of Surgeons National Surgical Quality Improvement Program database, including all patients undergoing elective OSR for AAA between 2011 and 2017. Excluded were patients with missing data on prior abdominal surgery, supramesenteric clamping, or urgent repairs. Patients with prior abdominal surgery (PAS) and patients without prior abdominal surgeries (nonPAS) were compared. The primary outcome was 30-day postoperative mortality. Secondary outcomes were operating time, ischemic colitis, postoperative complications, and lengths of hospital stay. Of the 2034 patients included, 27% had previous open abdominal surgery and 73% did not. Overall, the median age was 71(interquartile range 65-76), 72% of patients were male, 44% were smokers, and the average body mass index was 27kg/m2. Univariate analysis showed no difference in postoperative 30-day mortality (4.0% PAS vs. 4.1% nonPAS, P=0.91) or overall postoperative complication rates (33% PAS vs. 29% nonPAS, P=0.07). Previous open abdominal surgery was significantly associated with longer operating times (P=0.032) and an almost doubled rate of ischemic colitis (4.7% PAS vs. 2.6% nonPAS, P=0.02). Postoperative intensive care unit and hospitalization were also significantly longer in patients with prior abdominal surgery (P=0.005 and P=0.014, respectively). Finally, there were significantly less patients discharged home, as opposed to institutionalized care (75.7% PAS down from 82.4% nonPAS, P=0.001). Despite these initial univariate analysis results, on multivariate analysis, PAS actually did not prove to be a statistically significant independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. This study suggests that patients who have undergone PAS may have some disadvantages in OSR of AAA. However, these negative trends do not go so far as to statistically significantly identify PAS as an independent risk factor for 30-day mortality, ischemic colitis, or longer operating times. As such, we suggest that a history of previous open abdominal surgery, in and of its own, should not exclude patients from consideration for open aortic abdominal aneurysm repair.

Laparoscopic myomectomy is safe in patients with previous abdominal surgery

Aims: The excision of myomas is commonly carried out in symptomatic women who choose to preserve their uterus, either using an open or minimally invasive (hysteroscopy, laparoscopy, robotic) approach. Patient selection is a critical factor in achieving a successful laparoscopic myomectomy. Prior abdominal surgery was not defined as a risk factor, however, the safest approach in these cases is still the subject of intense debate The aim of this study was to evaluate the safety of laparoscopic myomectomy in patients with previous abdominal surgery.&#x0D; Methods: A retrospective cohort study was conducted on the files and operative notes of the patients who underwent laparoscopic myomectomy operation in a university-hospital based gynaecology department between January 2012 and March 2017. The patients were classified into two groups; Group 1 consisted of 34 patients who had previously undergone abdominal surgery, whereas the Group 2 comprised 118 patients who had not undergone any abdominal surgery.&#x0D; Results: There were no significant difference between patients with and without a history of abdominal surgery in terms of operation time, postoperative hospital stays, blood loss, rate of operative complications, or conversion rate to open surgery.&#x0D; Conclusion: A history of abdominal surgery seems to have no negative impact on the safety of a subsequent laparoscopic myomectomy.

VNOTES (vaginal natural orifice transluminal surgery) gynecologic procedures in morbidly and super-morbidly obese women: five year experience.

To analyze our experience with vNOTES gynecologic procedures in women with morbid and super morbid obesity to determine feasibility and compare outcomes with standard minimally invasive techniques. Gynecologic procedures performed by three surgeons on women with a body mass index (BMI) ≥ 40kg/m2 from 2017 to 2023. A subset of women with a BMI ≥ 50kg/m2 was also analyzed. 103 women with a BMI ≥ 40kg/m2 were identified (Class IV), 19 of whom had a BMI ≥ 50kg/m2 (Class V). For the entire population the mean BMI was 45.7kg/m2 (40-62). 29 women were nulliparous and 23 had at least one prior cesarean delivery. 51 had no prior abdominal surgery. The procedures performed were hysterectomy and removal of adnexae in 77 patients, hysterectomy alone in six, adnexal surgery alone in nine, and hysterectomy with adnexectomy and lymph nodes in five. Two surgeries were converted to laparoscopy and five to laparotomy. Average surgical time was 87min (30-232). Average blood loss was 82mL (10-400). Mean uterine weight was 206g (29-2890). 53 procedures were performed as outpatient, 44 had overnight observation, four had a length of stay of 2days, one each for 4days and 5days. The laparoscopies occurred in one patient with an obliterated cul-de-sac and in one patient for lymph node removal. The laparotomies occurred for adnexal adhesions in one, bleeding in two, a cystotomy in one requiring urology consultation, and an obliterated cul-de-sac One patient developed a postoperative vaginal cuff hematoma not requiring intervention. vNOTES gynecologic procedures are feasible in this high-risk population and may result in shorter recovery times and fewer complications than standard laparoscopy or transvaginal surgery. What does this study add to the clinical work: VNOTES approach is feasible in morbidly obese women and may have distinct advantages over conventional laparoscopic, vaginal or open techniques.

Safety of Laparoscopic Entry Points in Patients With a History of Abdominal Surgery: A Research Article.

This study aimed to assess the safety of laparoscopic entry sites in patients with previous abdominal surgery who subsequently required re-operation. This is a prospective study wherein the data of 118 patients who had undergone previous abdominal surgery and were subsequently re-operated at our center (Bakırköy Doctor Sadi Konuk Research and Study Hospital) were collected from October 2015 to October 2016. Careful attention was paid to gathering information regarding patients' age, parity, body mass index (BMI), type of previous surgery, type of incision made during previous surgery, and medical history. For this study, the abdomen was topographically divided into nine parts. During the operation, all quadrants were examined and evaluated for adhesion and the content of adhesion. Adhesions were found in 44% (55 out of 118) of the patients, while 56% (66 patients) had no adhesions in the abdomen. The majority of cases (74%) had a history of cesarean section, and 87%had a Pfannenstiel incision. Adhesions were reported in 37.5% (33 out of 88) of the patients with a previous history of cesarean section. A significant proportion of subjects with adhesion (83%) had anterior abdominal wall adhesions, including only the omentum, whereas 11.5% (six subjects) had umbilical adhesions. Subjects with a history of umbilical hernia repair had more adhesions. The present study sought to assess the safety of laparoscopic entry points in individuals with prior abdominal surgery. The rise in laparoscopic surgeries, favored for reduced wound infections and quicker recovery times, brings forth concerns about potential complications in those with previous abdominal operations. Historically, postoperative adhesions have been observed in a significant number of patients after gynecological procedures. Our research, however, found a lower adhesion rate, which could be due to the smaller size of our sample and fewer gynecological cases. Existing adhesions can complicate subsequent surgeries, increasing operational times and posing injury risks. Adhesions also elevate healthcare costs and patient morbidity and mortality. Moreover, complications like Trocar-related injuries, including damageto major organs, are pivotal. While certain trocar insertion techniques may have fewer complications, our results align with previous findings suggesting higher adhesion rates after non-gynecological surgeries. Therefore, alternative entry points or methods, such as the palmer site or direct trocar entry, are recommended for those with an abdominal surgery history. Notably, our study's limited sample size may affect its generalizability, urging future studies for broader insights. Comprehensive pre-surgery assessments are crucial to anticipate complications. Our research supports that laparoscopic surgeries are safe for many with prior abdominal surgery, but for certain patients, non-umbilical entry sites are advised to further mitigate risks. The umbilicus is one of the safest entry sites for primary trocar insertion in patients with a history of Pfannenstiel incision. However, the probability of umbilical adhesions is high in patients who have undergone umbilical mesh repair, median incision, or major abdominal surgery. In these patients, surgeons should prefer other laparoscopic entry sites, especially Palmer's point, rather than the umbilicus.

Technique and outcomes of robotic-assisted retroperitoneal radical nephrectomy.

Robotic retroperitoneal partial nephrectomy (rRPN) has numerous advantages over transperitoneal surgery, including direct access to the renal hilum and posterior tumors, and avoidance of the peritoneal cavity in patients with a hostile abdomen. Although the use of the retroperitoneal approach has increased over the last decade, there is little literature on robotic retroperitoneal radical nephrectomy (rRRN), which has similar benefits over the transperitoneal approach. The aim of this study was to describe our technique for robotic retroperitoneal nephrectomy (rRN) and assess its feasibility and outcomes at a high-volume center. A retrospective review of patients who underwent some form of rRN [rRRN, robotic retroperitoneal simple nephrectomy (rRSN), or robotic retroperitoneal nephroureterectomy (rRNU)] at a single institution between 2013 and 2023. Patient characteristics, operative data, and postoperative complication rates were assessed. The technique for rRN was detailed. A total of 13 renal units in 12 patients were included for analysis (7 rRRN, 5 rRSN, 1 rRNU). Median patient age was 64.0 years, and median body mass index (BMI) was 36.0 kg/m2. Indications for retroperitoneal surgery were prior abdominal surgery in all patients, including three with bowel diversions, super morbid central obesity in two patients, and a large ventral hernia in one patient. Median operative time was 213 minutes and median estimated blood loss (EBL) was 85 cc. Median postoperative length of stay (LOS) was 3 days, and only one patient experienced a Clavien-Dindo grade ≥3 complication within 90 days of surgery. The retroperitoneal approach for robotic-assisted nephrectomy is feasible and associated with similar outcomes as the transperitoneal approach. This approach may prove beneficial in select patients with significant prior abdominal surgery including those who are morbidly obese.

Pain With Differing Insufflation Pressures During Robotic Sacrocolpopexy: A Randomized Controlled Trial

ABSTRACT Pain after surgery may have different origins, such as incisions, affected viscera, surgical positioning, or peritoneal irritation from insufflation. Shoulder pain after gynecological laparoscopic surgery is a common concern thought to be associated with peritoneal irritation. Decreasing this pain is therefore a target for improvement of analgesic requirements and overall postoperative pain. This study aimed to determine changes in postoperative pain, surgical safety, and analgesic use via decreased insufflation pressures. The study was designed as a single-blinded, randomized clinical trial at a singular medical center within the United States where surgical treatment took place for pelvic organ prolapse via robotic-assisted sacrocolpopexy. Included were women 18 years or older who were able to complete the visual analog scale without assistance and who underwent scheduled robotic-assisted sacrocolpopexy. After inclusion, participants were randomized in a 1:1 ratio to undergo robotic-assisted sacrocolpopexy with peritoneal insufflation pressure at either 12 mm Hg (experimental) or 15 mm Hg (standard). Surgeries were performed by a single board-certified urogynecologist and resident assistant using a standard technique, the DaVinci Xi system, and an 8-mm AirSeal assist port. Surgeons and assisting OR professionals were not blinded to insufflation pressure. On the first postoperative day, all participants were asked to rate pain via a visual analog scale, as well as at 2 weeks postoperatively (with the addition of a PGI-I questionnaire). The 2-week surveys were collected by the principal investigator or primary surgeon (unblinded). A Likert scale of 0 to 10 was used to rate the highest preoperative and postoperative pain in the postanesthesia care unit. At the time of surgery, preoperative analgesia and opioid use were verified with active prescription records. After surgery, data were recorded for operative time, analgesic doses, conversion to laparotomy or increased insufflation pressure, additionally performed procedures, estimated blood loss, and length of stay. Enrollment occurred from April 27, 2021, to May 17, 2022, with final follow-up being completed on June 1, 2022. A total of 80 participants were enrolled, with 41 in the experimental insufflation group, and 39 in the standard insufflation group. Baseline differences did not exist between groups for prior abdominal surgeries, medical comorbidities, leading edge of prolapse, age, or body mass index. Although median preoperative pain was recorded as zero for both groups, the standard insufflation group did report a statistically higher pain level in the postoperative period. Furthermore, women in the experimental/lower insufflation group used statistically fewer morphine milliequivalents immediately after surgery as well as after discharge. There were no apparent operative problems significantly associated with lower insufflation pressures, as operative time, estimated blood loss, and length of stay in the hospital were not significantly different between groups. The analysis found that the use of 12 mm Hg insufflation pressure did lower opioid use and pain levels in comparison with 15 mm Hg in the immediate postoperative period. The use of this method proved both feasible and safe in all cases, without blood loss, operating time changes, or changes in completing cases through minimal invasive mess. These encouraging findings provide a zero-cost, surgeon-driven intervention method for the postoperative period of robotic gynecological surgeries with the potential lower patient pain levels and opioid use.

Comparison of Abdominal Initial Entry Techniques in Gynecological Laparoscopy

Objective: The aim of this study is to assess the safety of laparoscopic entry techniques.&#x0D; Materials and Methods: Within the scope of the study, medical records of patients who underwent laparoscopy due to various gynecological indications at our clinic between January 1, 2011, and July 1, 2015, were examined. Evaluation was conducted using our hospital’s electronic database.&#x0D; Results: In the patient cohort, direct trocar placement was preferred in 91.8% (1025 patients), Veress needle placement was used in 7.4% (82 patients), and an open technique was used in 0.8% (9 patients). In terms of entry sites, umbilicus was the most commonly chosen option, being preferred in 97.2% (1085 patients) of cases. In 2.4% of patients (27 patients), the midline abdominal trocar was preferred as the initial trocar insertion site. Among these patients, suprapubic incision was preferred in 62% (17 patients), while Lee-Huang point was chosen as the entry site in 38% (10 patients).Looking at the history of previous surgeries, 18.5% (206 patients) had a history of prior abdominal surgery, and 3.5% (39 patients) had undergone two previous surgical procedures. Only 0.1% (1 patient) had undergone three or more abdominal surgeries.&#x0D; Discussion: In conclusion, no clear superiority of one initial entry technique over another has been proven. Despite the extensive literature on laparoscopic entry, debates regarding the most effective method to prevent significant complications continue.

Evaluating mesh use for abdominal donor site closure after deep inferior epigastric perforator flap breast reconstruction: A systematic review and meta-analysis.

Despite improvement in abdominal morbidity with deep inferior epigastric perforator (DIEP) flap breast reconstruction compared to prior abdominally-based free flap breast reconstruction, abdominal bulge, and hernia rates have been cited anywhere from 2% to 33%. As a result, some surgeons utilize mesh or other reinforcement upon donor-site closure, but its benefit in preventing abdominal wall morbidity has not been well-defined for DIEP flaps. The purpose of this systematic review is to evaluate DIEP donor-site closure techniques and the impact of mesh type and plane on abdominal-wall morbidity including hernia and bulge, relative to primary fascial closure. MEDLINE, PubMED, Cochrane Library, and SCOPUS were systematically reviewed for studies evaluating DIEP flap breast reconstruction abdominal-donor site closure, where any mesh reinforcement or primary fascial closure was specified, and postoperative outcomes of hernia and/or abdominal bulge were reported. Analysis was performed in Review Manager (RevMan) evaluating mesh use, type, and plane relative to primary fascial closure, using the Mantel-Haenszel method to calculate odds ratios (ORs) of significance level p < .05, and a random effects model to account for inter-study heterogeneity. Of the 2791 DIEP patients across 11 studies, 1901 patients underwent primary closure and 890 were repaired with mesh. When hernia and/or bulge were combined into a single complication, the use of any mesh did not significantly reduce its odds compared to primary closure (OR = 0.69, p = .20). Similarly, the use of any mesh did not significantly reduce the odds of bulge alone compared to primary closure (OR = 0.62, p = .43). However, the odds of hernia alone were significantly reduced by 72% with any mesh use (OR = 0.28, p = .03). Mesh use was significantly associated with decreased odds of hernia alone with DIEP flap surgery, but there was no difference in bulge or combined hernia/bulge rates. As bulge is the more common abdominal morbidity after DIEP flap harvest in a patient with no prior abdominal surgery or risk factor for hernia, mesh use is not indicated in abdominal closure of all DIEP patients. Future prospective studies are warranted to characterize the specific indications for mesh use in the setting of DIEP flap surgery.

Prognostic value of peritoneal scar-like tissue in patients with peritoneal metastases of ovarian origin presenting for curative-intent cytoreductive surgery

BackgroundComplete cytoreductive surgery (CRS), remain the gold standard in the treatment of peritoneal metastases of ovarian cancer (PMOC). Given the increasing rate of neoadjuvant chemotherapy in patients with high PCI, prior abdominal surgeries, inflammation and fibrotic changes, the benefit of removing any “peritoneal scar-like tissues” (PST) during CRS, hasn’t been thoroughly investigated. Our objective in this retrospective cohort was to identify the proportion of malignant cells positivity in PST of patients with PMOC, undergoing curative-intent CRS ± HIPEC.MethodsThis is a retrospective study, conducted at our comprehensive cancer center, including patients with PMOC, presenting for curative-intent CRS. During CRS, benign-looking peritoneal lesions, lacking the typical hard nodular, aggressive, and invasive morphology, were systematically resected or electro fulgurated. PSTs were analyzed for the presence of tumoral cells by our pathologist. Correlations between the presence of PST and their positivity, and the different patients’ variables, were studied.ResultsIn 51% of patients, PST harbored malignant cells. Those were associated with poorly differentiated serous tumors, a high PCI (> 8) and a worse DFS: 17 months in the positive PST group versus 29 months in the negative PST group (p = 0.05), on univariate analysis. Multivariate analysis revealed that PCI > 8 and poorly differentiated primary tumor histology were correlated with a worse DFS, and that higher PCI and advanced FIGO were correlated with a worse OS.ConclusionBenign-looking PST harbors malignancy in 51% of cases. The benefit of their systematic resection and their prognostic value should be further investigated in larger cohorts.

Comparison of long-term quality of life outcomes between endoscopic vacuum therapy and other treatments for upper gastrointestinal leaks.

While endoscopic vacuum assisted closure (EVAC) therapy is a validated treatment for gastrointestinal leaks, its impact on long-term quality of life (QoL) is uncertain. The purpose of this study was to evaluate the impact of successful EVAC management on long-term QoL outcomes. An institutional review board approved prospectively maintained database was retrospectively reviewed to identify patients undergoing treatment for gastrointestinal leaks between June 2012 and July 2022. The Short-Form 36 (SF-36) survey was used to assess QoL. Patients were contacted by telephone and sent the survey electronically. QoL outcomes between patients who underwent successful EVAC therapy and those who required conventional treatment (CT) were analyzed and compared. A total of 44 patients (17 EVAC; 27 CT) completed the survey and were included in our analysis. All included patients had foregut leaks with sleeve gastrectomy being the most common sentinel operation (n = 20). The mean time from the sentinel operation was 3.8years and 4.8years for the EVAC and CT groups, respectively. When evaluating long-term QoL, the EVAC group scored higher in all QoL domains when compared to the CT group with physical functioning (87.3 vs 69.3, p = 0.04), role limitations due to physical health (84.1 vs 45.7, p = 0.02), energy/fatigue (60.0 vs 40.9, p = 0.04), and social functioning (86.2 vs 64.1, p = 0.04) reaching statistical significance. Overall, patients who achieved organ preservation via successful EVAC therapy scored higher in all domains with role limitations due to physical health (p = 0.04) being statistically significant. In a multivariable regression analysis, increased age and a history of prior abdominal surgery at the time of the sentinel operation were patient characteristics that negatively impacted QoL outcomes. Patients with gastrointestinal leaks successfully managed by EVAC therapy have better long-term QoL outcomes when compared to patients undergoing other treatments.

Risk factors for adverse outcomes following paraesophageal hernia repair among obese patients.

Although obesity is an established risk factor for adverse outcomes after paraesophageal hernia repair (PEHR), many obese patients nonetheless receive PEHR. The purpose of this study was to explore risk factors for adverse outcomes of PEHR among this high-risk cohort. We hypothesized that obese patients may have other risk factors for adverse outcomes following PEHR. A retrospective study of adult obese patients who underwent minimally invasive PEHR from 2017 to 2019 was performed. Patients were excluded for BMI < 30 or if they had concomitant bariatric surgery at time of PEHR. The primary outcome of interest was a composite adverse outcome (CAO) defined as having any of the four following outcomes after PEHR: persistent GERD > 30 d, persistent dysphagia > 30 d, recurrence, or reoperation. Chi-square and t-test analysis was used to compare demographic and clinical characteristics. Multivariable logistic regression analysis was used to evaluate independent predictors of CAO. In total, 139 patients met inclusion criteria with a median follow-up of 19.7months (IQR 8.8-81). Among them, 51/139 (36.7%) patients had a CAO: 31/139 (22.4%) had persistent GERD, 20/139 (14.4%) had persistent dysphagia, 24/139 (17.3%) had recurrence, and 6/139 (4.3%) required reoperation. On unadjusted analysis, patients with a CAO were more likely to have a history of prior abdominal surgery (86.3% vs 70.5%, p = 0.04) and were less likely to have undergone a preoperative CT scan (27.5% vs 45.5%, p = 0.04). On multivariable analysis, previous abdominal surgery was independently associated with an increased likelihood of CAO whereas age and preoperative CT scan had a decreased likelihood of CAO. Although there were adverse outcomes among obese patients, minimally invasive PEHR may be feasible in a subset of patients at specialized centers. These findings may help guide the appropriate selection of obese patients for PEHR.

Clinical Benefits of Laparoscopic Adhesiolysis during Peritoneal Dialysis Catheter Insertion: A Single-Center Experience.

Background and Objectives: In peritoneal dialysis (PD) therapy, intra-abdominal adhesions (IAAs) can cause catheter insertion failure, poor dialysis function, and decreased PD adequacy. Unfortunately, IAAs are not readily visible to currently available imaging methods. The laparoscopic approach for inserting PD catheters enables direct visualization of IAAs and simultaneously performs adhesiolysis. However, a limited number of studies have investigated the benefit/risk profile of laparoscopic adhesiolysis in patients receiving PD catheter placement. This retrospective study aimed to address this issue. Materials and Methods: This study enrolled 440 patients who received laparoscopic PD catheter insertion at our hospital between January 2013 and May 2020. Adhesiolysis was performed in all cases with IAA identified via laparoscopy. We retrospectively reviewed data, including clinical characteristics, operative details, and PD-related clinical outcomes. Results: These patients were classified into the adhesiolysis group (n = 47) and the non-IAA group (n = 393). The clinical characteristics and operative details had no remarkable between-group differences, except the percentage of prior abdominal operation history was higher and the median operative time was longer in the adhesiolysis group. PD-related clinical outcomes, including incidence rate of mechanical obstruction, PD adequacy (Kt/V urea and weekly creatinine clearance), and overall catheter survival, were all comparable between the adhesiolysis and non-IAA groups. None of the patients in the adhesiolysis group suffered adhesiolysis-related complications. Conclusions: Laparoscopic adhesiolysis in patients with IAA confers clinical benefits in achieving PD-related outcomes comparable to those without IAA. It is a safe and reasonable approach. Our findings provide new evidence to support the benefits of this laparoscopic approach, especially in patients with a risk of IAAs.

(401) Insertion of A 2-Piece Inflatable Penile Prosthesis with Combined General and Regional Anesthesia

Abstract Introduction Inflatable penile prosthesis placement is widely used for treatment of medically refractory erectile dysfunction. In patients with prior pelvic or abdominal surgery, use of a 2-piece inflatable penile prosthesis avoids the need for placement of a reservoir in the pelvis, which can be a complicated procedure due to possible retropubic scarring. A pudendal nerve block can be employed as a regional anesthesia strategy for penile surgery to reduce use of intraoperative and postoperative opiates. Objective This video covers the placement of a 2-piece inflatable penile prosthesis under general and regional anesthesia in a patient with a complex surgical history. Methods The video demonstrates a step-by-step technique for the pudendal nerve block and placement of the 2-piece prosthesis. Results A 63-year-old male with history of multiple abdominal and pelvic surgeries was treated severe, refractory ED with insertion of a 2-piece inflatable penile prosthesis under general and regional anesthesia. He did not require any intraoperative opiates. He had a normal and uneventful postoperative recovery with a reduced postoperative opiate requirement. The prosthesis cycled properly four weeks after surgery. Conclusions In select patients undergoing insertion of a penile prosthesis, the use of a pudendal nerve block in combination with general anesthesia can reduce the perioperative opiate requirement.
