BACKGROUND: Anastomotic leaks remain one of the most dreaded complications in gastrointestinal surgery causing significant morbidity, that negatively affect the patients\' quality of life. Experimental studies play an important role in understanding the pathophysiological background of anastomotic healing and there are still many fields that require further investigation. Knowledge drawn from these studies can lead to interventions or techniques that can reduce the risk of anastomotic leak in patients with high-risk features. Despite the advances in experimental protocols and techniques, designing a high-quality study is still challenging for the investigators as there is a plethora of different models used.
OBJECTIVE: To review current state of the art for experimental protocols in high-risk anastomosis in rats.
METHODS: This systematic review was performed according to The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. To identify eligible studies, a comprehensive literature search was performed in the electronic databases PubMed (MEDLINE) and Scopus, covering the period from conception until 18 October 2023.
RESULTS: From our search strategy 102 studies were included and were categorized based on the mechanism used to create a high-risk anastomosis. Methods of assessing anastomotic healing were extracted and were individually appraised.
CONCLUSIONS: Anastomotic healing studies have evolved over the last decades, but the findings are yet to be translated into human studies. There is a need for high-quality, well-designed studies that will help to the better understanding of the pathophysiology of anastomotic healing and the effects of various interventions.

A 36-year-old female at 36 weeks\' gestation presented with right upper quadrant abdominal pain. She had no prior surgeries. Her pregnancy had been uncomplicated up until her presentation. Abdominal ultrasound was negative for cholecystitis or cholelithiasis, and the appendix was not visualized. During the second day of her hospital course, an abdominal magnetic resonance imaging (MRI) was performed revealing dilated small intestine with air-fluid levels and an inverted-appearing, prominent cecum. She was urgently taken to the operating room for cesarean section followed by abdominal exploration. After delivery of the child, a cecal bascule was found, with a severely distended cecum. To our knowledge, this is the first report of a cecal bascule diagnosed by MRI, and the first diagnosis of cecal bascule in a pregnant patient requiring surgical intervention. We discuss the pathophysiology, diagnosis and treatment of cecal bascule and review the current literature of reported cases.

Objective: The objective of the study was to systematically investigate the outcomes of Liposomal Bupivacaine following major colorectal resections. Patients and methods: We conducted a comprehensive literature search of PubMed, Medline, Google scholar, Cochrane Central Registry and clinical trials.gov databases through May 2017 for studies published regarding liposomal bupivacaine. Studies were filtered based on relevance to perioperative analgesia in colorectal resections. Data comparing type of study, techniques of resection, mode of administration of liposomal bupivacaine, details of control group, outcomes were collected. Results: A total of 1008 patients from seven studies were included in this systematic review and meta-analysis. The studies were mostly retrospective or prospective cohort studies with one randomized controlled trial (RCT). Meta-analysis showed that liposomal bupivacaine was associated with decreased length of stay, standard mean difference in days (SMD) - 0.34, (95% confidence intervals [CI] - 0.56, -0.13, p = .001) and decreased IV opioid use (expressed as intravenous morphine equivalent in milligrams) in the first 48-72 h, SMD -0.49 (95% CI -0.69, -0.28, p < .00001). Pain scores were also significantly low in patients who received liposomal bupivacaine, SMD -0.56 (95% CI -1.07, -0.06, p = .03]. There was no significant difference in hospitalization costs between the two groups. Conclusions: Use of liposomal bupivacaine is associated with decreased IV opioid use, length of stay and lower pain scores. However, our data needs to be interpreted cautiously given the relative paucity of randomized controlled trials.

BACKGROUND: Perforation during colonoscopy is a rare but well recognized complication with significant morbidity and mortality. We aim to systematically review the currently available literature concerning care and outcomes of colonic perforation. An algorithm is created to guide the practitioner in management of this challenging clinical scenario.
METHODS: A systematic review of the literature based on PRISMA-P guidelines was performed. We evaluate 31 articles focusing on findings over the past 10 years.
CONCLUSIONS: Colonoscopic perforation is a rare event and published management techniques are marked by their heterogeneity. Reliable conclusions are limited by the nature of the data available - mainly single institution, retrospective studies. Consensus conclusions include a higher rate of perforation from therapeutic colonoscopy when compared to diagnostic colonoscopy and the sigmoid as the most common site of perforation. Mortality appears driven by pre-existing conditions. Treatment must be tailored according to the patient\'s comorbidities and clinical status as well as the specific conditions during the colonoscopy that led to the perforation.

BACKGROUND: Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery.
OBJECTIVE: This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis.
METHODS: We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7%) patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique); 21 (30%) patients underwent peritoneal laparoscopic lavage; 4 (5.7%) patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6%) patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy.
RESULTS: The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients). In the LPL group the morbidity rate was 33.3%.
CONCLUSIONS: Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage.

OBJECTIVE: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields.
METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria.
RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications.
CONCLUSIONS: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

Following the successful introduction of robotic surgery to the field of urology and gynecology, its use gained even more interest among those in the field of colorectal surgery. Rectal resection is believed to be among the best suited for robotic assistance. In particular, the right hemicolectomy procedure has been proposed as a training tool in order to gain clinical experience with the robot. This article and attached video demonstrates, in detail, the robot-assisted right hemicolectomy, including key landmarks of the procedure. The case presented involved a 58-year-old man with an advanced cecal adenocarcinoma. In our opinionrobot-assisted right colon resection is a procedure that offers particular value for the novice robotic team who is in the beginning stages of their colorectal surgery experience. Although no concrete advantages for use of the robot in this particular procedure have been demonstrated in the literature, because it is a relatively straightforward and simple procedure, it can serve as a valuable training tool for the novice robotic surgeon.
