3D laparoscopic left colectomy with intraoperative colonoscopy: a live educational procedure
In this live educational procedure, Dr. Armando Melani presents the case of a 70-year-old female patient with a previous history of inferior right lobectomy secondary to T2 carcinoma. In 2018, during postoperative surveillance, PET-scan showed a left colon fixation. Colonoscopy revealed a polypoid lesion located 40cm away from the anal verge. Biopsy showed severe dysplasia. Endoscopic clips were placed for marking purposes. Three additional adenomatous polyps in the right, transverse, and left colon were found and removed. Preoperative abdominal X-ray showed the presence of clips at the level of the left pelvic bone. Since colonoscopy was performed more than two weeks before surgery, intraoperative colonoscopy was used to ensure tumor location.

During the video, surgical pitfalls were highlighted, and the author showed the importance of preoperative tumor tattooing, demonstrated anatomical landmarks, and the starting point of mesenteric dissection for left colectomy at the superior mesenteric vein (IMV). Recommendations for inferior mesenteric artery (IMA) ligation, hypogastric nerve preservation, splenic flexure mobilization, stapling recommendations during colon transection, colorectal anastomosis, and means to prevent postoperative complications were provided. The value of leak test, endoscopic anastomosis evaluation, and the use of indocyanine green (ICG) were also emphasized.

Fully laparoscopic right colectomy for caecal tumor with “vessels first’ approach
Over the last few years, laparoscopic colorectal surgery has increased exponentially worldwide. When combined with an enhanced recovery program, a significant reduction in the length of hospital stay can be achieved, coupled with an early return to normal activities for the patient.
This is the case of a 68-year-old obese woman with a BMI of 30 presenting with a caecal tumor. Her major co-morbidities are chronic obstructive pulmonary disease (COPD) and high blood pressure. The patient complained of chronic abdominal pain and presented a positive fecal occult blood test. Colonoscopy showed a caecal tumor. Biopsy confirmed an adenocarcinoma. CT-scan did not show any distant metastasis. A full laparoscopic approach with a medial-to-lateral and ‘vessels first’ approach is shown.

Complex cases in laparoscopic recurrent and incisional hernia repair: multi-recurrence, infections, fistulas, difficult abdomen
The term ‘‘complex (abdominal wall) hernia’’ is often used by general surgeons and other specialists working in the abdomen to describe abdominal wall hernias which are technically challenging and time-consuming.

Four categories were created to classify and discuss the criteria, which were proposed to be included in the definition of ‘‘complex abdominal wall hernia’’: defect size and location, patient history and risk factors, contamination and soft tissue condition, and clinical scenario.
Defect size is an important variable; increased size is a risk factor for 30-day readmission rate and recurrence.
Wound contamination is usually classified according to the US National Research Council Group including clean, clean-contaminated, contaminated, and dirty/infected. It is well-known that contamination and subsequent infection are an important cause of wound dehiscence and reherniation which impair wound healing dynamics.
A recurrent hernia is considered a risk factor for a new recurrence.
Patient status is an important factor. Conditions such as abnormal collagen type I/type III ratio and genetic connective tissue disorders are associated with an increased risk of herniation. Older age, male gender, chronic pulmonary disease, coughing, ascites, jaundice, anemia, emergency surgery, wound infection, obesity, steroid use, hypoalbuminemia, hypertension, perioperative shock are also important risk factors.

The reported incidence of incisional hernia is about 2 to 11% after all laparotomies.
The ideal repair for an abdominal incisional hernia is to restore the anatomical and physiological integrity of the abdominal wall by reconstructing the midline. However, 30 to 50% of defects larger than 6cm recur after primary closure.
The insertion of a synthetic mesh helps to decrease or relieve tension on the suture line and can reduce the incidence of recurrence to 10% or less.
But foreign prosthetic materials have been associated with a high risk of complications such as protrusion, extrusion, infection, and intestinal fistulization.
Laparoscopic repair has provided further improvements with lower infection rates, shorter hospital stay, and a reduction in recurrence with rates of 4 to 16% in recent studies.
In this topic addressing complex laparoscopic cases, we show different scenarios including recurrent infected incisional hernia, fistulization, multi-recurrent incisional hernia, migration, and conversion.

Laparoscopic Spigelian hernia repair
Spigelian hernia is a rare condition and it is difficult to diagnose it clinically. It has been estimated to account for 0.12% of abdominal wall hernias. The hernia ring is a well-defined defect in the transversus abdominis aponeurosis. The hernia sac, surrounded with extraperitoneal adipose tissue, often lies interparietally passing through the transversus abdominis and the internal oblique muscle aponeuroses and then spreading out beneath the intact aponeurosis of the external oblique muscle. The laparoscopic repair is well-established. Most authors use a transperitoneal approach either by placing the mesh in an intraperitoneal position or by raising the peritoneal flap and placing the mesh in the extraperitoneal space. In this video, we demonstrate the laparoscopic repair of a Spigelian hernia through the transabdominal preperitoneal (TAPP) placement of a composite mesh.

ERCP in a patient with previous subtotal gastrectomy for cancer: hybrid approach with transjejunal access
Endoscopic retrograde cholangiopancreatography (ERCP) in patients with prior gastric surgery (Roux-en-Y gastric bypass, partial or subtotal gastrectomy) is a challenging procedure. Despite technological advances in endoscopy, reaching the duodenum and entering the bile duct remains difficult. Laparoscopic assisted ERCP (LAERCP) allows the duodenum to be accessed through the excluded stomach in case of previous RYGB or through the proximal jejunum in case of gastric resection. The objective of this video is to demonstrate the hybrid approach in a patient with a previous subtotal gastrectomy for gastric cancer.

Laparoscopic appendectomy for recurrent appendicitis after medical treatment
Appendectomy is the only curative treatment of appendicitis. However, the management of patients with an appendiceal mass or abscess can be temporarily managed medically with intravenous antibiotic therapy and/or percutaneous drainage. And yet, there are many controversies over the non-operative management of acute appendicitis. In 2015, Fair et al. used data from the American College of Surgeons National Surgical Quality Improvement Project to evaluate 30-day morbidity and mortality of intervention (laparoscopic and open appendectomy) at different time periods. A delay of operative intervention longer than 48 hours was associated with a doubling of complication rates. Elective appendectomy can be performed after 6 to 8 weeks later, which proves successful in the vast majority of patients.
This is the case of an 83-year-old man who presented with an acute appendicitis treated medically in another hospital. The patient had a past medical history of arterial hypertension, cardiomyopathy, previous cerebral ischemia, and rectal polyp. A delayed appendectomy was planned. However, before the procedure, a total colonoscopy was performed because of the history of polyps. This elderly patient was hospitalized for colonoscopy. At admission, he presented with fever, right iliac fossa tenderness, and a biological inflammatory syndrome. A CT-scan was performed. It showed a recurrent acute appendicitis without mass, with a 2cm abscess on the tip of the appendix. An appendectomy was performed in this case.

Laparoscopic postpartum right diaphragmatic hernia reduction
A 35-year-old patient was referred to our emergency department for acute abdominal pain and respiratory distress. The patient gave natural childbirth three days before the episode, a childbirth without immediate complications.
Clinically, the patient presented with tachypnea, tachycardia, and desaturation, nauseas and constipation, depressible abdomen with generalized pain on palpation. The absence of vesicular murmur and right lung dullness were noted.
Blood lab findings showed increased inflammatory parameters.
An abdominothoracic CT-scan with contrast was performed. It showed a voluminous right diaphragmatic hernia containing the omentum, a distended colon and liver segment VIII with signs of hypoperfusion.
A surgical procedure was performed. A laparoscopic approach was performed and the patient’s hiatal hernia was reduced by closing the defect with a non-absorbable suture and by placing a Vicryl mesh.
The patient recovered with no complications and was discharged on postoperative day 3.

Live interactive transanal TME (TaTME) with the TEO™ platform
Randomized clinical trials such as COLOR II, COREAN and CLASICC, have shown better results for laparoscopic total mesorectal excision (TME), in terms of short-term and long-term outcomes, when compared with open TME.
Laparoscopic TME presents some limitations such as low rectal cancer which has a high risk of leaving a positive circumferential resection margin (CRM) and a narrow pelvis. Conversion to open procedures remains unsatisfactory.
Transanal TME (taTME) has been proposed to give a new option in cases where laparoscopic TME is difficult.
In this video, we present the case of a transanal approach with the TEO™ platform for low rectal cancer.

Laparoscopic appendectomy after appendicular phlegmon
Appendicitis is one of the main reasons for consultation and surgical interventions in the emergency departments around the world. If it is not diagnosed and treated timely, it can evolve towards an appendicular perforation, and as a result, it can become a peritonitis or an appendicular phlegmon. This latter case may occur in approximately 10% of cases.
Currently, the management of the appendicular phlegmon is controversial. Some authors prefer to perform an appendectomy immediately, and others are in favor of medical treatment using antibiotic therapy and percutaneous drainage if possible and delay appendectomy.
In this case, we present a patient presenting with an appendicular phlegmon in which a conservative management with percutaneous drainage and delayed surgery were decided upon.

The VERSA LIFTER BAND™: a new option for liver retraction in laparoscopic Roux-en-Y gastric bypass for morbid obesity
During laparoscopic bariatric procedures in morbidly obese patients, the surgeon's operative view is often obscured by the hypertrophic adipose left lobe of the liver.
To provide adequate operative views and working space, an appropriate retraction of the left liver lobe is required.
The use of a conventional liver retractor mandates an additional subxiphoid wound, resulting in patient discomfort for pain and scar formation, with the additional risk of iatrogenic liver injury during retraction maneuvers.
To overcome these limitations, we present the use of a simple, rapid, and safe technique for liver retraction using the VERSA LIFTER™ Band disposable liver suspension system or retractor.
