Pelvic Floor Peritoneal Closure to Prevent Postoperative Ileus in Mid-Low Rectal Cancer Surgery

The goal of this clinical trial is to determine whether closing the pelvic floor peritoneum during laparoscopic radical resection of mid-low rectal cancer can reduce the incidence of postoperative ileus. This study will also assess the impact of pelvic floor peritoneal closure on patient recovery and quality of life after surgery. The main questions it aims to answer are: 1. Can closing the pelvic floor peritoneum reduce the incidence of ileus within 30 days after surgery in patients with mid-low rectal cancer? 2. What is the impact of pelvic floor peritoneal closure on postoperative complications such as anastomotic leakage and pelvic infection? 3. How do the two surgical approaches differ in their effects on patients' postoperative anal function, urinary function, and quality of life? Researchers will compare two approaches after laparoscopic radical resection for rectal cancer: closing the pelvic floor peritoneum versus not closing it, to observe which method more effectively prevents postoperative ileus. Participants will: 1. Undergo laparoscopic radical resection with anus preservation for mid-low rectal cancer 2. Receive either pelvic floor peritoneal closure or non-closure treatment based on random assignment 3. Attend regular follow-up visits to evaluate intestinal function recovery and occurrence of complications 4. Complete quality of life questionnaires (EORTC QLQ-C30 scale) at 6 months after surgery

Rectus Sheath Catheters Following Midline Laparotomy

Rectus sheath catheters (RSC) are used for postoperative analgesia following midline laparotomies. Local anesthetics are applied to the posterior rectus sheath via the RSC. The target structures are the anterior cutaneous branches of the spinal nerves Th7-Th12. RSC can be used in particular if thoracic epidurals are contraindicated (compromised coagulation), technically unfeasible or refused by the patient. The study investigates placebo-controlled weather RSC have a significant additional analgesic effect in a multimodal analgesic concept. Primary outcome parameters are the maximum pain score, the Quality-of-Recovery-15-Score (QoR-15GE) and the opioid consumption (morphine equivalents) in the first 72h postoperatively.

Study of Treatment With Intensified Omeprazole Treatment to Prevent High Output Stoma 1

The goal of this clinical trial is to evaluate if intensified omeprazole therapy can reduce high-output stoma (HOS) in adults undergoing ileostomy formation surgery. The main objectives of the study are: * To assess if intensified omeprazole treatment significantly reduces mean daily ileostomy output (ml/24h) during the first three postoperative days compared to standard omeprazole treatment. * To evaluate the proportion of patients meeting the criteria for high-output stoma (HOS ≥1400 ml/day) on consecutive postoperative days. * To measure the time required for stabilization of ileostomy output (\<1400 ml/day maintained for three consecutive days). * To determine the incidence of dehydration-related complications, specifically electrolyte disturbances (hyponatremia, hypokalemia). * To compare the length of initial hospital stay, frequency of rehospitalizations within 30 days post-discharge, and total length of hospital stay (including rehospitalizations). Researchers will compare 10 days intensified omeprazole treatment (loading dose of 80 mg IV followed by 40 mg IV twice daily) with standard treatment (40 mg IV once daily) to determine the effectiveness of intensified dosing in reducing ileostomy output and improving postoperative outcomes. Participants will: * Receive either standard or intensified intravenous omeprazole during their hospitalization and after discharge for 10 days combined. * Undergo daily measurements of ileostomy output. * Have routine laboratory assessments of electrolyte levels. * Participate in follow-up assessments up to 30 days post-discharge, conducted either through outpatient visits or telephone consultations.

Prevention of Postoperative Hernias in Emergency Surgery

The aim of this observational study is to understand the risk factors and incidence of postoperative hernias among patients undergoing emergency surgery. The main question it aims to answer is: What is the incidence of postoperative hernias in this group of patients? A brief telephone interview will be conducted with participants who will be included in this study one year after the surgery. If the presence of a postoperative hernia is suspected, the patient will be invited to a follow-up visit to the surgical clinic, where the diagnosis will be confirmed by imaging tests.
