Colectomy and desmoid tumours in familial adenomatous polyposis: a systematic review and meta-analysis

Desmoid tumours (DT) are one of the main causes of death in patients with familial adenomatous polyposis (FAP). Surgical trauma is a risk factor for DT, yet a colectomy is inevitable in FAP to prevent colorectal cancer. This systematic review and meta-analysis aimed to synthesize the available evidence on DT risk related to type, approach and timing of colectomy. A search was performed in MEDLINE, EMBASE and the Cochrane Library. Studies were considered eligible when DT incidence was reported after different types, approaches and timing of colectomy. Twenty studies including 6452 FAP patients were selected, all observational. No significant difference in DT incidence was observed after IRA versus IPAA (OR 0.99, 95% CI 0.69–1.42) and after open versus laparoscopic colectomy (OR 0.88, 95% CI 0.42–1.86). Conflicting DT incidences were seen after early versus late colectomy and when analysing open versus laparoscopic colectomy according to colectomy type. Three studies reported a (non-significantly) higher DT incidence after laparoscopic IPAA compared to laparoscopic IRA, with OR varying between 1.77 and 4.09. A significantly higher DT incidence was observed in patients with a history of abdominal surgery (OR 3.40, 95% CI 1.64–7.03, p = 0.001). Current literature does not allow to state firmly whether type, approach, or timing of colectomy affects DT risk in FAP patients. Fewer DT were observed after laparoscopic IRA compared to laparoscopic IPAA, suggesting laparoscopic IRA as the preferred choice if appropriate considering rectal polyp burden.

Effectiveness of Postoperative Pain Management By Multimodal Analgesia Without Epidural Analgesia After Laparoscopic Colon Cancer Surgery: A Prospective Cohort Study

Background:Although epidural analgesia has been recommended for its strong analgesic effect for postoperative analgesia management, the increasing number of patients undergoing anticoagulant or antiplatelet therapy to treat cerebrocardiovascular diseases cannot receive epidural analgesia given the risk of serious complications, including epidural hematoma. We aimed to evaluate the analgesic effects of multimodal analgesia involving intravenous patient-controlled analgesia (IV-PCA), and repeated scheduled acetaminophen administration, and block as local anesthesia, to establish postoperative analgesia management method replacing epidural analgesia in laparoscopic colectomy.Methods:We enrolled patients undergoing laparoscopic surgery for colorectal cancer at our hospital. The primary outcome was days of postoperative hospital stay. The efficacies of multimodal and epidural analgesia were compared. The secondary outcomes were the pain assessment and safety.Results:We registered 48 patients; among them, 40 patients were eligible. The mean postoperative hospital stay was 9.00 days (95% CI = 8.19 to 9.39, p < 0.0001). There were relatively high pain scores from postoperative day (POD) 0-1, which subsequently decreased and reach their lowest value at POD 4-5.Conclusions:Multimodal analgesia with IV-PCA and repeated scheduled acetaminophen administration could provide a safe and effective analgesic effect after laparoscopic colectomy and may be a postoperative analgesia management alternative to epidural analgesia.

Is Prophylactic Abdominal Drainage Necessary After Laparoscopic Colectomy For Colon Cancer? A Propensity Score-Matched Analysis

Background: In 2018, the Enhanced Recovery After Surgery (ERAS) Society recommended against routine drainage after colorectal surgery. However, the evidence is relatively old and few studies were performed in low-to-middle income country (LMIC) setting. This study aimed to compare outcomes of laparoscopic colectomy with and without prophylactic drainage for colon cancer.Methods: A retrospective study was performed from 2018 to 2021 with patients who underwent laparoscopic colectomy with D3 lymphadenectomy for colon cancer. The use of prophylactic drainage was depended on routine practice of surgeons. Outcomes were postoperative complications and postoperative hospital length of stay. The drain and no-drain groups were compared using propensity score-matched (PSM) analysis.Results: The study included 143 patients (59 in the drain group and 84 in the no-drain group). The PSM resulted in 94 patients (47 in each group). Median age was 62 years. The most frequent was right hemicolectomy (33.6%), followed by left hemicolectomy (32.2%), sigmoid colectomy (21%), extended right hemicolectomy (9.8%), transverse hemicolectomy (2.1%), and total colectomy (1.4%). Postoperative hospital stay was significantly shorter in the no-drain group (median of 5 versus 6 days). The no-drain group also had lower rate of complications (23.8% versus 30.5% and 23.4% versus 34% before and after matching respectively) and less severe complications based on Clavien-Dindo classification, but the difference was not significant.Conclusions: Laparoscopic colectomy without prophylactic drainage is safe in the treatment of colon cancer. This approach can shorten postoperative hospital stay and should be applied even in the LMIC setting.Main novel aspect: Laparoscopic colectomy without prophylactic drainage for colon cancer can be applied in low-to-middle income settings.

Long-term Oncological Outcomes of Totally Laparoscopic Colectomy With Intracorporeal Anastomosis for Colon Cancer: Propensity Score Matching Analysis

Background: This retrospective study aimed to compare long-term oncological outcomes between laparoscopic-assisted colectomy (LAC) with extracorporeal anastomosis (EA) and totally laparoscopic colectomy (TLC) with intracorporeal anastomosis (IA) for colon cancers, including right- and left-sided colon cancers.Methods: Patients with stage I–III colon cancers who underwent elective laparoscopic colectomy between January 2013 and December 2017 were analyzed retrospectively. Patients converted from laparoscopic to open surgery and R1/R2 resection were excluded. Propensity score matching (PSM) analysis (1:1) was performed to overcome patient selection bias.Results: A total of 388 patients were reviewed. After PSM, 83 patients in the EA group and 83 patients in the IA group were compared. Median follow-up was 56.5 months in the EA group and 55.5 months in the IA group. Estimated 3-year overall survival (OS) did not differ significantly between the EA group (86.6%; 95% confidence interval (CI), 77.4–92.4%) and IA group (84.8%; 95%CI, 75.0–91.1%; P = 0.68). Estimated 3-year disease-free survival (DFS) likewise did not differ significantly between the EA group (76.4%; 95%CI, 65.9–84.4%) and IA group (81.0%; 95%CI, 70.1–88.2%; P = 0.12).Conclusion: TLC with IA was comparable to LAC with EA in terms of 3-year OS and DFS. TLC with IA thus appears to offer an oncologically feasible procedure.

Pressure Support versus Spontaneous Ventilation during Anesthetic Emergence—Effect on Postoperative Atelectasis: A Randomized Controlled Trial

Background Despite previous reports suggesting that pressure support ventilation facilitates weaning from mechanical ventilation in the intensive care unit, few studies have assessed its effects on recovery from anesthesia. The authors hypothesized that pressure support ventilation during emergence from anesthesia reduces postoperative atelectasis in patients undergoing laparoscopic surgery using the Trendelenburg position. Methods In this randomized controlled double-blinded trial, adult patients undergoing laparoscopic colectomy or robot-assisted prostatectomy were assigned to either the pressure support (n = 50) or the control group (n = 50). During emergence (from the end of surgery to extubation), pressure support ventilation was used in the pressure support group versus intermittent manual assistance in the control group. The primary outcome was the incidence of atelectasis diagnosed by lung ultrasonography at the postanesthesia care unit (PACU). The secondary outcomes were Pao2 at PACU and oxygen saturation measured by pulse oximetry less than 92% during 48 h postoperatively. Results Ninety-seven patients were included in the analysis. The duration of emergence was 9 min and 8 min in the pressure support and control groups, respectively. The incidence of atelectasis at PACU was lower in the pressure support group compared to that in the control group (pressure support vs. control, 16 of 48 [33%] vs. 28 of 49 [57%]; risk ratio, 0.58; 95% CI, 0.35 to 0.91; P = 0.024). In the PACU, Pao2 in the pressure support group was higher than that in the control group (92 ± 26 mmHg vs. 83 ± 13 mmHg; P = 0.034). The incidence of oxygen saturation measured by pulse oximetry less than 92% during 48 h postoperatively was not different between the groups (9 of 48 [19%] vs. 11 of 49 [22%]; P = 0.653). There were no adverse events related to the study protocol. Conclusions The incidence of postoperative atelectasis was lower in patients undergoing either laparoscopic colectomy or robot-assisted prostatectomy who received pressure support ventilation during emergence from general anesthesia compared to those receiving intermittent manual assistance.

Laparoscopic Management of Benign Colorectal Diseases

Background: Laparoscopic colectomy is safe and effective, and in some cases, superior to open surgery, for a range of benign illnesses. The short-term advantages include less gastrointestinal discomfort, decreased wound infection and surgical morbidity, quicker bowel function restoration, and a shorter duration of hospital stay.Aim of the work & Methodology: evaluate our practice in laparoscopic colectomy by studied 20 patients with benign colorectal disorders admitted to our university hospital between Dec. 2015 and Dec. 2020. Inclusion criteria: 1. Age ranging from 15 to 70 years. 2. Patients with benign colorectal diseases, e.g., diverticular diseases, inflammatory bowel diseases, colonic polyps, rectal prolapse, etc. Exclusion criteria; malignant colorectal tumors and relative contraindication for laparoscopy. We were using classical laparoscopic techniques. Patients were discharged from the hospital when they could tolerate a regular diet. They were followed up at least six months, starting on the 30th postoperative day on a regular visit every two weeks—the data recorded including the intraoperative events and the difficulties and postoperative follow-up.Results: Technical difficulties are more remarkable for benign conditions than for cancer, especially for patients with inflammatory bowels, such as diverticular disease or inflammatory bowel disease, which frequently involve adjacent structures, peri-colic fibrosis, and lost planes. Surgeons should choose their patients before beginning laparoscopic colorectal surgeries.Conclusions: Laparoscopic surgery provides numerous advantages over open surgery, including minor discomfort, a shorter hospital stay, reduced morbidity, and a faster postoperative recovery. Our study cannot be utilized in a comparison study since it only evaluates our practice, and the findings may not be generalizable.
