Post-operative paralytic ileus (POI) occurs after surgery because of gastrointestinal dysfunction caused by surgical invasion. We therefore investigated the frequency of POI after laparoscopic colorectal surgery in patients with colorectal cancer using a strictly defined POI diagnosis and identified associated risk factors.Patients who underwent initial laparoscopic surgery for colorectal cancer between January 2014 and December 2018 were included. The primary end point was the incidence of POI. A multivariate logistic regression analysis revealed the contributing risk factors for POI.Of the 436 patients, 94 (21.6%) had POI. Compared with the non-POI group, the POI group had significantly higher frequencies of infectious complications (p 0.001), pneumonia (p 0.001), intra-abdominal abscess (p = 0.012), anastomotic leakage (p = 0.016), and post-operative bleeding (p = 0.001). In the multivariate analysis, the right colon (odds ratio [OR] 2.180, p = 0.005), pre-operative chemotherapy (OR 2.530, p = 0.047), pre-operative antithrombotic drug (OR 2.210, p = 0.032), and post-operative complications of CD grade ≥ 3 (OR 12.90, p 0.001) were independent risk factors for POI.Post-operative management considering the risk of post-operative bowel palsy may be necessary for patients with right colon, pre-operative chemotherapy, pre-operative antithrombotic drug or severe post-operative complications.

Background: Although inguinal hernia occurs frequently after radical prostatectomy, transabdominal preperitoneal (TAPP) inguinal hernia repair occasionally poses challenges due to fibrosis of the p...

The question as to whether laparoscopic surgery should be applied for inguinal hernia after radical prostatectomy remains a debate due to surgical difficulty arising from adhesions in the prevesical space. We report the surgical technique used in our department, its outcomes, and its safety and effectiveness compared with the surgical outcomes of primary transabdominal preperitoneal inguinal hernia repair (TAPP) cases. From February 2013 to January 2017, 30 patients with inguinal hernia were treated with TAPP after radical prostatectomy. At our institution, to avoid bladder injury, we dissect the prevesical space with the layer between the transversalis fascia and superficial layers of the preperitoneal fascia as the dissection plane. The practitioners were three qualified surgeons. Surgical outcome were compared with those of primary TAPP cases. For statistical analyses, we used t test to compare the mean operative durations and Chi square test to compare all other surgical outcomes. The median observation period was 19 months. Intraoperative and postoperative complications did not occur; no onset of recurrence and chronic pain was observed. The mean operative duration was 116.2 min, which was significantly longer than that of primary TAPP patients (87.9 min). However, the operative duration for the last 14 patients had reduced to 101.6 min, which was not significantly different from that of primary TAPP patients. In TAPP for patients following prostatectomy, surgery can be performed safely and reliably without prolonging the operative duration by selecting a skilled practitioner and standardizing the technique.

The appropriate surgical treatment for inguinal hernia in patients with liver cirrhosis and ascites remains controversial. A 79-year-old male undergoing treatment for Child–Pugh B hepatitis C-induced liver cirrhosis and hepatocellular carcinoma complicated with bilateral inguinal hernia underwent transabdominal preperitoneal (TAPP) repair. During surgery, barbed sutures were used to facilitate appropriate peritoneal closure. His postoperative course was uneventful. Information on TAPP repair for inguinal hernia in patients with liver cirrhosis and ascites is limited. The International Guidelines for Inguinal Hernia Management recommend Lichtenstein repair for patients with ascites. TAPP repair requires peritonectomy via a posterior endoscopic approach; therefore, proper peritoneal closure is important to prevent the leakage of ascitic fluid. Herein, TAPP repair was safely and successfully completed using barbed sutures to achieve proper and strong peritoneal closure. TAPP repair using barbed sutures can be an effective treatment option for patients with liver cirrhosis and ascites.

The aim of this study was to reveal the short-term and long-term outcomes of single-incision laparoscopic colorectal resection (SILC) compared with multi-incision laparoscopic colorectal resection (MILC) for colorectal cancer using propensity score matching analysis.The study group included 235 patients who underwent SILC and 730 patients who underwent MILC for colorectal cancer between April 2009 and September 2014. The propensity score matching for age, gender, body mass index, tumor location (right-sided colon/sigmoid colon/upper rectum), lymph node dissection (D1/D2/D3), pathologic T (≤T3) stage and TNM (0-I/II/III) stage produced 107 matched pairs. The exclusion criteria for SILC were as follows: (1) tumors located at the transverse, descending colon or lower rectum, (2) stage IV tumors, synchronous or previous malignancies, (3) locally advanced tumorsT4, (4) acute obstructions or previous major abdominal surgery and (5) obese patients: BMI30.No significant differences were observed in operating time, bleeding volumes, starting time of liquid diet and length of hospital stay between the SILC and MILC groups. However, the SILC group showed less analgesic requirements (1.1 vs. 1.9 times; p = 0.0006) and shorter length of incision (2.7 vs. 4.3 cm; p = 0.0000) compared to MILC group. The overall rate of postoperative complications was similar in both groups (2.8 vs. 3.7%, p = 0.70). The 5-year overall survival rate of SILC and MILC was 100 and 95% (p = 0.125) and 5-year disease-free survival rates in stages 0-III were 97 and 94% (p = 0.189), 100 and 92% in stage II and 90 and 85% in stage III, respectively.This study suggests that SILC for colorectal cancer is a safe and feasible option with better cosmetic results and less pain in strictly selected patients. SILC can also produce good oncological results with similar postoperative outcomes to MILC.
