Totally Laparoscopic Ileocolic Resection with Intracorporeal Anastomosis for Crohn's Disease: A Comparative Study.

BACKGROUND: Although minimally invasive surgery for Crohn's disease has been validated in previous studies, most of those reports have referred to laparoscopic-assisted procedures with an extra-corporeal anastomosis. OBJECTIVES: To evaluate the short- and long-term outcomes of total laparoscopic ileocolic resection with an intracorporeal anastomosis for Crohn's disease patients. METHODS: We conducted a single-center retrospective review of all patients who underwent primary ileocolic resection for Crohn's disease between 2010 and 2021. Group A included 34 patients who underwent total laparoscopic ileocolic resection with intracorporeal anastomosis. Group B comprised 144 patients who underwent an open or laparoscopic-assisted procedure. RESULTS: No differences were noted in operative time (mean 167 minutes vs. 152 minutes, P = 0.122), length of stay (median 6.4 days vs. 7.5 days, P = 0.135), readmission rates (11.8% vs. 13.2%, P = 1), and microscopic involvement of surgical margins (7.7% vs. 18.5%, P = 0.249). Group A had significantly fewer postoperative surgical site infections (2.9% vs. 22.2% respectively, P = 0.013), with no differences in other complications prevalence. After a median follow-up of 46 months, there were similar rates of endoscopic recurrence (47.1% vs. 51.4%, P = 0.72), clinical recurrence (35.3% vs. 47.9%, P = 0.253), and surgical recurrence (2.9% vs. 4.9%, P = 0.722). CONCLUSIONS: Total laparoscopic ileocolic resection with intracorporeal anastomosis for Crohn's disease is safe and resulted in favorable outcomes in terms of postoperative wound healing. The long-term disease recurrence rates were like those of laparoscopic-assisted and open ileocolic resection.

Long-term outcomes following ileocolic resection for Crohn's disease: does earlier elective resection affect disease recurrence rates?

BACKGROUND: Surgical resection in Crohn's disease is sometimes the only alternative treating disease complications or refractory disease. The implications of early resection on disease course are still debatable. We aimed to assess the influence of preoperative disease duration on long-term postoperative disease course. METHODS: A retrospective analysis of all Crohn's disease patients who underwent an elective primary ileocolic resection between 2010 and 2021 in a single tertiary medical center. The cohort was divided based on disease duration, Group A (47 patients) had a disease duration shorter than 3 years (median of 1 year) and Group B (139 patients) had a disease duration longer than 3 years (median of 11 years). RESULTS: Surgeries were less complex among Group A as noted by higher rates of laparoscopic assisted procedures (68.1% vs. 45.3%, P = 0.006), shorter surgery duration (134 vs. 167 min, P < 0.0001) less estimated blood loss (72.5 vs. 333 mL, P = 0.016) and faster return of bowel function (3 vs. 4 days, P = 0.011). However, propensity score matching nullified all the differences. Younger age (OR = 0.86, P = 0.004), pre-op steroids (OR = 3.69, P = 0.037) and longer disease duration (OR = 1.18, P = 0.012) were found to be independently significantly associated with severe complications. After a median follow-up time of 71.38 months no significant differences were found between the groups in terms of endoscopic (P = 0.59), or surgical recurrences rates (P = 0.82). CONCLUSIONS: The main effect of preoperative short disease duration was noted within the surgical complexity; however, matching suggests confounders as cause of the difference. No significant long-term implication was noted on disease recurrence.

Increased risk for incisional hernia following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

INTRODUCTION: The incidence of incisional hernias (IH) after midline laparotomy varies from 11% to 20%. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is potentially prone to hernias because a Xiphoid to pubis laparotomy incision performed on patients who have undergone previous abdominal surgeries with the addition of chemotherapy and its related adverse effects. METHODS: We performed a retrospective analysis on a prospectively maintained single institution database from March 2015 to July 2020. The inclusion criteria were patients who underwent CRS-HIPEC and had at least 6 months postoperative follow-up with post-operative cross-sectional imaging study. RESULTS: Two hundred and one patients were included in the study. All patients underwent CRS-HIPEC with resection of previous scar and umbilectomy. Fifty-four patients were diagnosed with IH (26.9%). The major risk factors for IH in multivariate analysis were higher American society of Anesthesiologists score (ASA) (OR 3.9, P = 0.012), increasing age (OR 1.06, P = 0.004) and increasing BMI (OR 1.1, P = 0.006). Most of the hernia sites were median (n = 43, 79.6%). Eleven (20.4%) patients had lateral hernias due to stoma incisions or drain sites. Most of the median hernias were at the level of the resected umbilicus 58.9% (n = 23). Five (9.3%) of the patients with IH necessitated an urgent surgical repair. CONCLUSION: We have demonstrated that more than a quarter of the patients after CRS-HIPEC suffer from IH and up to 10% of them may require surgical intervention. More research is needed to find the appropriate intraoperative interventions to minimize this sequela.

Resection of Recurrent Pelvic Soft Tissue Sarcoma: Is the Risk Worth the Reward?

INTRODUCTION: Soft tissue sarcomas (STS) of the pelvis present a surgical and oncological challenge. We investigated the outcomes of patients undergoing resection of pelvic sarcomas. METHODS: A retrospective analysis of all patients who underwent surgical resection for STS between 2014 and 2021 at a tertiary academic referral center (n = 172). Included all patients with primary or recurrent STS which originated or extended to the pelvic cavity (n = 29). RESULTS: The cohort was divided into primary pelvic sarcomas (n = 18) and recurrent pelvic sarcomas (rPS, n = 11). Complete R0/R1 resection was achieved in 26 patients (89.6%). The postoperative complication rate was 48.3%. The rate of major complications was 27.5%. The median time of follow-up from surgery was 12.3 months (range, 0.6-60.3 months). Disease-free survival was superior in the primary pelvic sarcomas group compared to the rPS group (P = 0.002). However, there was no significant difference in overall survival, (P = 0.52). Univariant and multivariant analyses identified rPS group (Hazard Ratio 8.68, P = 0.006) and resection margins (Hazard Ratio 6.29, P = 0.004) to be independently associated with disease-free survival. CONCLUSIONS: We have demonstrated that achieving R0/R1 resection is feasible. Oncological outcomes are favorable for primary tumors, whereas recurrent tumors exhibit early recurrences. Consideration of resection of recurrent pelvic STS should involve a careful multidisciplinary evaluation.

Pelvic Peritonectomy Poorly Affects Outcomes in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Colorectal Metastases.

BACKGROUND: Constraints of pelvic anatomy render complete cytoreduction (CRS) challenging. The aim of this study is to investigate the impact of pelvic peritonectomy during CRS/HIPEC on colorectal peritoneal metastasis (CRPM) patients' outcomes. METHODS: This is a retrospective analysis of a prospectively maintained CRS/hyperthermic intraperitoneal chemotherapy (HIPEC) database. The analysis included 217 patients with CRPM who had a CRS/HIPEC between 2014 and 2021. We compared perioperative and oncological outcomes of patients with pelvic peritonectomy (PP) (n = 63) to no pelvic peritonectomy (non-PP) (n = 154). RESULTS: No differences in demographics were identified. The peritoneal cancer index (PCI) was higher in the PP group with a median PCI of 12 vs. 6 in the non-PP group (p < 0.001). Operative time was 4.9 vs. 4.3 h in the PP and non-PP groups, respectively (p = 0.63). Median hospitalization was longer in the PP group at 12 vs. 10 days (p = 0.007), and the rate of complications were higher in the PP group at 57.1% vs. 39.6% (p = 0.018). Pelvic peritonectomy was associated with worse disease-free (DFS) and overall survival (OS) with 3-year DFS and OS of 7.3 and 46.3% in the PP group vs. 28.2 and 87.8% in the non-PP group (p = 0.028, p .> 0.001). The univariate OS analysis identified higher PCI (p = 0.05), longer surgery duration (p = 0.02), and pelvic peritonectomy (p < 0.001) with worse OS. Pelvic peritonectomy remained an independent prognostic variable, irrespective of PCI, on the multivariate analysis (p < 0.001). CONCLUSIONS: Pelvic peritonectomy at the time of CRS/HIPEC is associated with higher morbidity and worse oncological outcomes. These findings should be taken into consideration in the management of patients with pelvic involvement.

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.

Natural History and Management of Small-Bowel Obstruction in Patients After Cytoreductive Surgery and Intraperitoneal Chemotherapy.

BACKGROUND: Small-bowel obstruction (SBO) after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a common complication associated with re-admission that may alter patients' outcomes. Our aim was to characterize and investigate the impact of bowel obstruction on patients' prognosis. METHODS: This was a retrospective analysis of patients with SBO after CRS/HIPEC (n = 392). We analyzed patients' demographics, operative and perioperative details, SBO re-admission data, and long-term oncological outcomes. RESULTS: Out of 366 patients, 73 (19.9%) were re-admitted with SBO. The cause was adhesive in 42 (57.5%) and malignant (MBO) in 31 (42.5%). The median time to obstruction was 7.7 months (range, 0.5-60.9). Surgical intervention was required in 21/73 (28.7%) patients. Obstruction eventually resolved (spontaneous or by surgical intervention) in 56/73 (76.7%) patients. Univariant analysis identified intraperitoneal chemotherapy agents: mitomycin C (MMC) (HR 3.2, p = 0.003), cisplatin (HR 0.3, p = 0.03), and doxorubicin (HR 0.25, p = 0.018) to be associated with obstruction-free survival (OFS). Postoperative complications such as surgical site infection (SSI), (HR 2.2, p = 0.001) and collection (HR 2.07, p = 0.015) were associated with worse OFS. Multivariate analysis maintained MMC (HR 2.9, p = 0.006), SSI (HR 1.19, p = 0.001), and intra-abdominal collection (HR 2.19, p = 0.009) as independently associated with OFS. While disease-free survival was similar between the groups, overall survival (OS) was better in the non-obstruction group compared with the obstruction group (p = 0.03). CONCLUSIONS: SBO after CRS/HIPEC is common and complex in management. Although conservative management was successful in most patients, surgery was required more frequently in patients with MBO. Patients with SBO demonstrate decreased survival.

The Influence of Laparoscopic Sleeve Gastrectomy on Pregnancy, Delivery, and Infant: Does Timing of Pregnancy Following Laparoscopic Sleeve Gastrectomy Affect Outcomes?

PURPOSE: Maternal obesity is associated with newborn morbidity and mortality; however, the literature discussing bariatric surgical effects on women's fertility and pregnancy has reached diverse conclusions. We examined the effect of laparoscopic sleeve gastrectomy (LSG) on pregnancy, birth, and newborn outcomes regarding the time of conception. MATERIALS AND METHODS: We conducted a retrospective review of women who had LSG and conceived between 2007 and 2017. Data included maternal parameters, pregnancy progression, delivery, and newborn status. Pregnancies were divided into subgroups according to surgery to conception interval (≤ 12, 12-24, ≥ 24 months). RESULTS: We reviewed 68 patients: 48 (70%) conceived once, 13 (19%) conceived twice, 7 women (10%) conceived three times. There were 95 pregnancies and 80 live births. The group sizes were 18 (18.9%), 29 (30.5%), and 48 (50.5%) pregnancies for ≤ 12, 12-24, and 24 months after surgery, respectively. No difference was found between the subgroups regarding basic characteristics at time of surgery (age (p = 0.100), weight (p = 0.180), BMI (p = 0.616); and at beginning of pregnancy weight (p = 0.309), BMI (p = 0.707), %EBMIL (p = 0.321)). No significant differences were found concerning pregnancy progression, complications, and the newborns' weight (p = 0.41), GCT (p > 0.99), preeclampsia (p = 0.492), eclampsia (p > 0.99), Pre-term (p = 0.428), live birth (p = 0.432), LGA (p > 0.99), SGA (p = 0.732). A statistically significant trend of increased rates of caesarean section in subject with longer surgery-to-conception intervals was detected (P = 0.022). CONCLUSIONS: Our results did not show that the interval between LSG and conception affects the pregnancy and newborn outcomes. Therefore, we believe that early conception following LSG does not increase the risk of maternal or neonatal morbidity or mortality.

The pattern of peritoneal colorectal metastasis predicts survival after cytoreductive surgery and hyperthermic intra-peritoneal chemotherapy.

BACKGROUND: Peritoneal cancer index (PCI) has been used reliably to prognosticate patients with peritoneal metastasis, however, it fails to describe the patterns of peritoneal spread and to correlate these patterns to survival outcomes. We aim to define the scattered peritoneal spread (SPS) as a pattern associated with worse survival in colorectal peritoneal metastasis. METHODS: A retrospective analysis of metastatic colorectal cancer patients from a prospectively maintained database of peritoneal surface malignances (n = 280) between 2015 and 2020. SPS was defined by the presence of at least two distant and non-contiguous PCI regions. We compared patients with SPS (n = 73) and clustered peritoneal spread (CPS) (n = 88) for demographics, perioperative and survival outcomes. RESULTS: No difference in demographics or post-operative course was noted between the groups. The median follow-up was 15.4 months (0.4-70.8 months). Worse disease-free survival (DFS) in the SPS group with an estimated median of 8.2 months compared to 22.5 months in the CPS spread group, (p = 0.001). The estimated median overall survival (OS) for SPS group was 35.7 months whereas in the CPS group the median was not reached (p = 0.025). The same effect of SPS was preserved even after stratification of PCI. CONCLUSIONS: We defined and described the association of the peritoneal spread pattern to survival outcomes. SPS patients exhibit worse DFS and OS independent of the PCI level. Integration of malignant spread pattern into prognostication models along with PCI may aid in predicting oncological outcomes.

The impact of gastrointestinal anastomotic leaks on survival of patients undergoing cytoreductive surgery and heated intraperitoneal chemotherapy.

BACKGROUND: Gastrointestinal (GI) leaks after cytoreductive surgery and hyperthermic Intraperitoneal Chemotherapy (CRS/HIPEC) is a known life-threatening complication that may alter patients' outcomes. Our aim is to investigate risk factors associated with GI leaks and evaluate the impact of GI leaks on patient's oncological outcomes. METHODS: A retrospective analysis of perioperative and oncological outcomes of patients with and without GI leaks after CRS/HIPEC. RESULTS: Out of 191 patients included in this study, GI leaks were identified in 17.8% (34/191) of patients. Small bowel anastomoses were the most common site (44%). Most of the GI leaks were managed conservatively and re-operation was needed in 44.1% of cases. Univariate analysis identified higher PCI (p = 0.03), higher number of packed cells transfused (p = 0.036), pelvic peritonectomy (p = 0.013), high number of anastomoses (p = 0.003) and colonic resection (p = 0.042) as factors associated with GI leaks. Multivariate analysis identified stapled anastomoses (OR 2.59, p = 0.001) and pelvic peritonectomy (OR 2.33, p = 0.044) as independent factors associated with GI leaks. Disease-free survival tended to be worse in the leak group but did not reach statistical significance (p = 0.235). The 3- and 5-year OS was 73.2% and 52.9% in the leak group compared to 75.8% and 73.2% in the non-leak group (p = 0.236). CONCLUSIONS: GI leak showed no impact on overall and disease free survival after CRS/HIPEC.Avoidance of stapled reconstruction in high risk patients with high tumor burden and large number of anastomoses may yield improved outcomes.

Detection of Minimal Residual Disease in the Peripheral Blood of Breast Cancer Patients, with a Multi Marker (MGB-1, MGB-2, CK-19 and NY-BR-1) Assay.

PURPOSE: Minimal residual disease (MRD) refers to micrometastases that are undetectable by conventional means and is a potential source of disease relapse. This study aimed to detect the presence of breast cancer (BC) biomarkers (MGB-1, MGB-2, CK-19, NY-BR-1) using real-time polymerase chain reaction (RT-PCR) in peripheral blood mononuclear cells (PBMC) of BC patients and the impact of a positive assay on clinical outcome. PATIENTS AND METHODS: Patients in the analysis included females >18 years of age with biopsy-proven carcinoma of the breast. A 10 mL sample of venous blood was obtained from 10 healthy controls and 25 breast cancer patients. Comparisons of peripheral blood markers were made with clinicopathological variables. RESULTS: High-quality RNA was extracted from all samples with a mean RNA concentration of 224.8±155.3 ng/µL. Each of the molecular markers examined was highly expressed in the primary breast tumors (n = 3, positive controls) with none of the markers detected in healthy negative controls. The NY-BR-1 marker was expressed in one (4%) patient with metastatic disease with no MGB-1 and MGB-2 detected in any sample derived from the study patients. The CK-19 marker was detected in 16 (64%) of the BC cases. No correlation was found between CK-19 expression and tumor stage (P = 0.07) or nodal status (P = 0.32). No correlation was identified in the BC patients between CK-19 expression and receptor status in the BC primary tumor. CONCLUSION: This study showed high expression of all 4 markers NY-BR-1, MGB-1, MGB-2 and CK-19 in the PBMCs derived from breast cancer patients. CK-19 was detected in 64% of the stage I-III cases operated with curative intent, the only recurrent events occurring in the CK-19-positive cases. Our data confirm the need to enhance techniques for detection of MRD, which may better predict patients at risk for relapse.

Ratio of Pathological Response to Preoperative Chemotherapy in Patients Undergoing Complete Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Metastatic Colorectal Cancer Correlates with Survival.

BACKGROUND: Pathological response of colorectal peritoneal metastasis (CRPM) may affect prognosis. We investigated the relationship between oncological outcomes and pathological response to chemotherapy of CRPM following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: We conducted a retrospective analysis of a prospectively maintained Peritoneal Surface Malignancies database between 2015 and 2020. Analysis included patients with CRPM who underwent a CRS/HIPEC procedure (n = 178). The cohort was divided into three groups according to the response ratio (ratio of tumor-positive specimens to the total number of specimens resected): Group A, complete response; Group B, high response ratio, and Group C, low response ratio. RESULTS: The group demographics were similar, but the overall complication rate was higher in Group C (65.2%) compared with Groups A (55%) and B (42.8%) [p = 0.03]. Survival correlated to response ratio; the estimated median disease-free survival of Group C was 9.1 months (5.97-12.23), 14.9 months (4.72-25.08) for Group B, and was not reached in Group A (p = 0.001). The estimated median overall survival in Group C was 35 months (26.69-43.31), and was not reached in Groups A and B (p = 0.001). CONCLUSIONS: The pathological response ratio to systemic therapy correlates with survival in patients undergoing CRS/HIPEC. This study supports the utilization of preoperative therapy for better patient selection, with a potential impact on survival.

Restoring Intestinal Continuity in a Hostile Abdomen: The Deloyers Procedure.

BACKGROUND: Deloyers procedure enables anastomosis of the ascending colon to the rectum following extended resections that prevent usual fashion anastomosis. During the procedure, the right colon is completely mobilized and counterclockwise rotated to allow tension free and well-vascularized anastomosis while preserving the ileocecal valve. The purpose of this manuscript is to report our experience with laparoscopic Deloyers procedure in a hostile abdomen due to adhesions from previous surgeries. METHODS: We report the outcomes and our technique of laparoscopic Deloyers procedure in three patients. All patients had a surgical complication necessitating the creation of end colostomy with a short colonic remnant. The bowel status prevented restoration of continuity by the common colorectal anastomosis and laparoscopic Deloyers was elected. RESULTS: The procedure was successful in all patients, with no intra-operative complication and average surgery duration of three hours. Patients had uneventful postoperative recovery with only one case of minor complication and an adequate functional outcome. CONCLUSION: Laparoscopic Deloyers is safe and allows the restoration of bowel continuity with preservation of ileocecal valve and good functional outcome even in hostile abdomen.

Totally Laparoscopic Ileocolic Resection for Complex Enterovisceral Fistulas in Crohn's Disease: A Comparative Study.

INTRODUCTION: In primary Crohn's disease (CD), laparoscopic ileocolic resection has been shown to be both feasible and safe, and is associated with improved outcomes in terms of postoperative morbidity and length of hospital stay. However, it is unclear whether the laparoscopic approach can be routinely proposed as a safe procedure for patients with complex enterovisceral fistulas.The aim of this study is to assess the feasibility and safety of laparoscopic surgery for complex enterovisceral fistulas, and compare it with CD patients who underwent primary laparoscopic ileocolic resection. PATIENTS AND METHODS: All patients who underwent laparoscopic primary ileocolic resection (LICR) for complex enterovisceral fistulas between July 2006 and July 2017 were included. They were compared with all consecutive patients who underwent LICR for nonfistulizing CD in the same period of time. Patients with previous bowel resections or recurrent disease were excluded. RESULTS: Nineteen patients with 20 enterovisceral fistulas (group I) were compared with 61 patients who underwent LICR for nonfistulizing disease (group II). There were no differences between the groups in age, sex, preoperative body mass index, nutritional status, and American Society of Anesthesiology score. There was no conversion to open surgery in both groups.There were no significant differences between groups in terms of operative time [120 (range: 65 to 232) vs. 117 (range: 62 to 217) min, P=0.7], hospital stay [6 (5 to 8) vs. 7 (5 to 65) days, P=0.56], overall morbidity 26.3% versus 16.4% (P=0.33), major morbidity (Clavien-Dindo >3) 15.7% versus 10% (P=0.66) and reoperation rates 5.3% versus 4.9% (P=0.9). There was no mortality in both groups. CONCLUSIONS: Our experience shows that the laparoscopic approach for complex enterovisceral fistulas in selected CD patients is both feasible and safe in the hands of experienced inflammatory bowel disease surgeons with extensive expertise in laparoscopic surgery. Larger study cohorts are needed to confirm these findings.

Roux-en-Y Gastric Bypass Versus One Anastomosis Gastric Bypass as a Preferred Revisional Bariatric Surgery After a Failed Silastic Ring Vertical Gastroplasty.

BACKGROUND: Over the years, the silastic ring vertical gastroplasty (SRVG) has shown poor long-term outcomes with both weight regain and complications. Therefore, most bariatric surgeons have been presented with the need to perform a successful and safe conversion procedure. Yet the preferred and recommended conversion surgery regarding weight loss, comorbidity improvement, and postoperative complications remains under debate. OBJECTIVE: The aim of this study is to compare the outcomes of conversion from SRVG with either Roux-en-Y gastric bypass (RYGBP) or one anastomosis gastric bypass (OAGB). MATERIALS AND METHODS: A retrospective study was conducted from our bariatric surgery units' database. We reviewed the files of patients who underwent either a RYGBP or OAGB after a previous SRVG. Demographics, obesity-related comorbidities, BMI before and after the procedure, postoperative complications, and length of hospital stay were analyzed. RESULTS: Between May 2008 and August 2018, fifty-four patients underwent conversion from a failed SRVG. Twenty-one patients underwent conversion to OAGB (39%), and thirty-three patients underwent conversion to RYGBP (61%). Major complications were reported in 9.5% of the OAGB group and 15.1% of the RYGBP group. At a mean follow-up of 28 months, the OAGB group achieved a 78.5% excess BMI loss compared with 57.6% in the RYGBP group (p = 0.137). One patient (4.7%) of the OGBP group and 5 (15.1%) of the RYGBP group needed reoperations due to complications (p = 0.224). CONCLUSION: The OGBP is gaining popularity and evidence as an effective and safe procedure. Here we show the successful utilization of the OGBP, when compared with RYGBP, as a revisional procedure after SRVG.

Transanal total mesorectal excision for rectal cancer: Surgical outcomes and short-term oncological outcomes in a single-institution consecutive series.

INTRODUCTION: Rectal cancer surgery is continuously evolving. Transanal total mesorectal excision (TaTME) is a relatively new surgical approach with possible advantages in comparison to current standard surgical techniques. Several studies in recent years have validated this approach regarding safety and effectiveness. We describe our initial experience with TaTME evaluating surgical parameters, post-operative outcomes and short-term oncological outcomes. METHODS: This is a retrospective study reviewing all patients who underwent TaTME in a single institution from May 2015 to April 2018. RESULTS: The cohort included 25 patients with an average age of 60.4 (range: 40-86), of which 13 (52%) patients were male. The average body mass index was 26.1. The overall 30-day morbidity rate was 40%, with 20% (five cases) being severe complications, defined by Clavien-Dindo Grade of 3b or above. There were three major interoperative complications. Four cases (16%) required reoperation during the first 30 post-operative days. The median length of stay was 8 days. The surgery duration was on average 296 min (range: 205-510). Negative resection margins were achieved in all patients. At a median follow-up period of 14 months, there were no local recurrences, and 4 cases (16%) had a distant recurrence. CONCLUSION: This study describes our initial experience with TaTME, which requires a substantial learning curve to minimise complications and morbidity. Oncological outcomes as expressed by the resection margins, number of lymph nodes harvested and local recurrence rates were all comparable to previously published data.

Perioperative and Oncological Outcomes of Combined Hepatectomy with Complete Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Metastatic Colorectal Cancer.

BACKGROUND: Synchronous peritoneal and liver metastasis in colorectal cancer is a relative contraindication for curative surgery. We aimed to evaluate the safety and oncological outcomes of combined treatment of peritoneal and liver metastasis. METHODS: We conducted a retrospective analysis of metastatic colorectal cancer patients from two prospective databases: peritoneal surface malignancy (n = 536) and hepatobiliary (n = 286). We compared 60 patients treated with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) and hepatectomy; 80 patients treated with cytoreduction and HIPEC only; and 63 patients treated with hepatectomy alone. RESULTS: No differences in demographics were observed between the groups. Median hospital and intensive care unit (ICU) stay was shorter in group C (7 and 1 days, respectively) versus groups A and B (13 and 1 days, and 12 and 1 days, respectively; p < 0.001). Postoperative complications were not significantly different. Median follow-up was 18.6, 23.1, and 30.6 months for groups A, B, and C, respectively. Estimated 5-year overall survival (OS) was 48.8% (group A), 55.4% (group B), and 60.2% (group C) [p = 0.043 for group A vs. group C], and estimated 5-year disease-free survival (DFS) was 14.2% (group A), 23.0% (group B), and 18.6% (group C). Five-year OS was superior in group C compared with group A (p = 0.043), and DFS was superior in group C compared with groups A and B (p = 0.043 and 0.03, respectively). The peritoneum was the site of first recurrence in groups A and B (23.3% and 32.5%, respectively), and the liver was the site of first recurrence in group C (44.4%). CONCLUSIONS: We report favorable perioperative and oncological outcomes in combined cytoreduction/HIPEC and hepatectomy for patients with peritoneal and liver metastasis. Surgical intervention after multidisciplinary discussion should be considered in patients with both peritoneal and hepatic lesions when complete cytoreduction is feasible.

The Impact of the COVID-19 Pandemic on General Surgery Acute Admissions and Urgent Operations: A Comparative Prospective Study.

BACKGROUND: As part of the effort to control the coronavirus disease-19 (COVID-19) outbreak, strict emergency measures, including prolonged national curfews, have been imposed. Even in countries where healthcare systems still functioned, patients avoided visiting emergency departments (EDs) because of fears of exposure to COVID-19. OBJECTIVES: To describe the effects of the COVID-19 outbreak on admissions of surgical patients from the ED and characteristics of urgent operations performed. METHODS: A prospective registry study comparing all patients admitted for acute surgical and trauma care between 15 March and 14 April 2020 (COVID-19) with patients admitted in the parallel time a year previously (control) was conducted. RESULTS: The combined cohort included 606 patients. There were 25% fewer admissions during the COVID-19 period (P < 0.0001). The COVID-19 cohort had a longer time interval from onset of symptoms (P < 0.001) and presented in a worse clinical condition as expressed by accelerated heart rate (P = 0.023), leukocyte count disturbances (P = 0.005), higher creatinine, and CRP levels (P < 0.001) compared with the control cohort. More COVID-19 patients required urgent surgery (P = 0.03) and length of ED stay was longer (P = 0.003). CONCLUSIONS: During the COVID-19 epidemic, fewer patients presented to the ED requiring acute surgical care. Those who did, often did so in a delayed fashion and in worse clinical condition. More patients required urgent surgical interventions compared to the control period. Governments and healthcare systems should emphasize to the public not to delay seeking medical attention, even in times of crises.

Laparoscopic revision to total gastrectomy or fistulo-jejunostomy as a definitive surgical procedure for chronic gastric fistula after laparoscopic sleeve gastrectomy.

BACKGROUND: Staple-line leaks (SLL) after sleeve gastrectomy (SG) are a rare but serious complication requiring radiologic and endoscopic interventions with varying degrees of success. When failed, a chronic gastrocutaneous fistula forms with decreasing chances of closure with time. Definitive surgical management of chronic SLL after SG include laparoscopic revision to total/subtotal gastrectomy (LTG/LSTG) or a fistulo-jejunostomy (LRYFJ), both with Roux-en-Y reconstruction. OBJECTIVES: Comparison of SG revisions to LTG/LSTG versus LRYFJ as a definitive treatment for chronic SLL. SETTING: High-volume bariatric unit. METHODS: Retrospective review of a prospectively maintained database identified 17 patients with chronic gastric fistula after SG that were revised to either LTG/LSTG or LRYFJ between September 2011 and May 2020. Demographic characteristics, clinical data, quality of life, and laboratory values for both options were compared. RESULTS: Of the 17 conversions, 8 were revised to LTG/LSTG and 9 to LRYFJ. Mean age and body mass index at revision were 36.85 years (range, 21-66 yr) and 29 kg/m2 (range, 21-36 kg/m2), respectively. Average preoperative endoscopic attempts was 5 (range, 1-16). The overall average operation time of revision was 183 minutes (range, 130-275 min) with no significant difference between either conversion options. Mean follow-up time was 46.5 months (range, 1-81 mo) and was available for 10 patients (58.8%). Food intolerance was significantly better after revision to LRYFJ (n = 6/6, 100% versus n = 1/5, 20%, P < .05). There were no significant differences between revisional procedures and laboratory abnormalities. CONCLUSION: Laparoscopic revision to LRYFJ is a safe and feasible treatment for chronic SLL.
