Laparoscopic hemicolectomy

Complete splenic flexure mobilization is a critical step in left-sided colorectal resections. Surgeons use three approaches-anterior, medial, and lateral-to divide peritoneal ligaments connecting the left colon. The decision to perform mobilization varies, with minimal impact on post-operative outcomes but longer surgery times and rare complications. Pancreatic injury risk is low, though other structures, like arteries and the duodenum, may be at risk. Our video outlines the medial trans-mesocolic approach, with the patient positioned in lithotomy...

Background Anastomosis formed in minimally invasive laparoscopic right hemicolectomy (LRH) may be achieved intra-corporeally (ICA) or extra-corporeally (ECA). This study compared the return of bowel function and other associated early patient outcomes and morbidity rates after an ICA or ECA in LRH. Methodology The study conducted a single-center retrospective cohort study of elective LRH from January 2021 to September 2023. Patient demographics, surgical techniques, and outcomes were analyzed using IBM SPSS Statistics for Windows, Version 29...

INTRODUCTION: Appendiceal tumors are rare neoplasms detected in about 2 % of appendicectomies. The clinical presentation is often unspecific, varying from unspecific abdominal pain or presenting as an acute appendicitis or being asymptomatic. CASE PRESENTATION: We present a case of a patient presenting as an acute appendicitis with a mucocele, and then classified as HAMN. The patient was treated with initial laparoscopic approach and then conversion in laparotomy with appendectomy...

BACKGROUND: During laparoscopic left hemicolectomy procedures, a previously overlooked consistently thick blood vessel within the gastrocolic ligament near the splenic hilum may contribute to post-operative bleeding complications. The purpose of this study was to investigate the identification and management of the previously overlooked blood vessel. METHODS: This is a retrospective descriptive study of patients undergoing laparoscopic left colectomy for splenic fexure cancer conducted at a national gastrointestinal surgery centre in China...

The key steps of performing a laparoscopic right hemicolectomy with transvaginal natural orifice specimen extraction surgery.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide, and screening colonoscopy has led to a decreasing incidence rate. However, the incidence of CRC is increasing among young people, especially adolescents and young adults (AYAs) who are not routinely screened. Although CRC is the fourth most common cancer among AYAs, it is extremely rare. In younger patients, CRC is often diagnosed later, and the proportion of patients with advanced CRC is higher than that in older patients...

BACKGROUND: APC and MUTYH are both well-known colorectal polyposis causative genes. However, 30-50% of colorectal adenomatous polyposis cases are classified as colonic adenomatous polyposis of unknown etiology and lack identifiable pathogenic variants. Although guidelines recommend total proctocolectomy for colonic adenomatous polyposis of unknown etiology with over 100 adenomas, evidence is lacking. This study presents a unique case of localized colonic adenomatous polyposis of unknown etiology with multiple adenocarcinomas, treated with hemicolectomy and regional lymph node dissection...

Intramural intestinal hematoma is a rare disease, one of the triggering factors of which is the use of anticoagulants. In previous reports, most patients were on treatment with warfarin. Herein, we report a case of direct-acting oral anticoagulant (DOAC)-induced intramural hematoma of the ascending colon in a patient refractory to conservative treatment and required laparoscopic right hemicolectomy. An 80-year-old male patient with a history of atrial fibrillation and cerebral infarction, on treatment with apixaban, was brought to our hospital with the chief complaints of abdominal pain, vomiting, and melena...

BACKGROUND: Postoperative nausea and vomiting (PONV) refers to nausea and vomiting that occurs within 24-h after surgery or in the post-anesthesia care unit (PACU). Previous studies have reported that the use of remimazolam, a newer benzodiazepine (BDZ) hypnotic, for anesthesia results in less PONV. In this study, we compared the rate of PONV between sevoflurane and remimazolam after general anesthesia. METHODS: In this prospective randomized controlled trial (RCT), participants aged 20-80 years who underwent elective laparoscopic cholecystectomy or hemicolectomy were randomized to either the remimazolam or sevoflurane group...

OBJECTIVE: To assess the possibilities of fluorescent detection system in qualitative and quantitative assessment of bowel perfusion in colorectal resections. MATERIAL AND METHODS: From May to August 2023, a single-center pilot cross-sectional unblinded study with inclusion of 18 patients with colon cancer (of left-sided - 12, of right-sided - 6, mean age - 72.9 years, m/w - 61/39%) was conducted. All patients underwent laparoscopic colorectal resections with extracorporeal stage of bowel transection...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

An 89-year-old man was diagnosed with a submucosal tumor suspected to be a lipoma and was followed up for 6 years. The patient was admitted to the hospital because of increased tumor size and morphological changes despite negative bioptic findings. The lesion was diagnosed as an advanced adenocarcinoma of the ascending colon (cT3N0M0, cStage IIa). Laparoscopic-assisted right hemicolectomy with D3 lymph node dissection was performed. Pathological diagnosis of a surgically resected specimen revealed adenocarcinoma with lipohyperplasia (pT3N2aM0, pStage IIIb)...

INTRODUCTION: Either extracorporeal anastomosis (EA) or intracorporeal anastomosis (IA) could be selected for digestive reconstruction in laparoscopic right hemicolectomy (LRH). However, whether LRH with IA is feasible and beneficial for overweight right-side colon cancer (RCC) is unclear. This study aims to investigate the feasibility and advantage of IA in LRH for overweight RCC. METHODS: Forty-eight consecutive overweight RCC patients undergoing LRH with IA were matched with 48 consecutive cases undergoing LRH with EA...

Urinary dysfunction following treatment for rectal adenocarcinoma is a common and complex complication. We present a case of a 69-year-old male who underwent laparoscopic-assisted left hemicolectomy and loop ileostomy after receiving chemotherapy and radiation therapy for rectal adenocarcinoma. Postoperatively, it was incidentally discovered the patient had urinary frequency and urgency. Cystoscopy revealed radiation changes to the bladder walls and a bladder leak was confirmed by cystogram. The patient underwent successful repair of the urinary bladder leak, with challenges posed by prior radiation therapy...

BACKGROUND: Appendiceal mucinous neoplasms (AMNs), although not classified as rare, are relatively uncommon tumors most often discovered incidentally during colorectal surgery. Accurate identification of AMNs is difficult due to non-specific symptoms, overlapping tumor markers with other conditions, and the potential for misdiagnosis. This underscores the urgent need for precision in diagnosis to prevent severe complications. CASE SUMMARY: This case report describes the unexpected discovery and treatment of a low-grade AMN (LAMN) in a 74-year-old man undergoing laparoscopic hemicolectomy for transverse colon adenocarcinoma (AC)...

BACKGROUND: Appendiceal intussusception is a pathological condition in which the appendix is inverted into the cecum, which may cause symptoms that resemble those of other gastrointestinal disorders and may induce intestinal obstruction. The rarity of this case presentation is the co-occurrence of appendiceal intussusception and cecal adenocarcinoma, a combination that to our knowledge has not previously been reported in the medical literature. This case provides new insights into the complexities of diagnosing and managing overlapping pathologies...

BACKGROUND: The article describes our initial experience using CMR Versius platform for several procedures in general surgery. METHODS: Between September 2022 and April 2023, seventy patients underwent robotic surgery in a multi-robotic referral center (San Paolo University Hospital, Milan, Italy). Three surgeons with only laparoscopic experience performed 24 cholecystectomies, 13 inguinal hernia repairs, 9 ventral hernia repairs, 7 right hemicolectomies, 11 left hemicolectomies, 1 sigmoidectomy, 1 ileocecal resection, 1 ventral rectopexy, 1 Nissen fundoplication, 1 total splenectomy, and 1 exploration with multiple biopsies...

Colorectal cancer, the third most common cancer worldwide, affects 40-45% of patients on the right side. Surgery, especially minimally invasive methods such as laparoscopic and robotic procedures, is the preferred treatment. However, these techniques present technical complications. The anatomical complexity and variations in vessel branching patterns pose challenges, particularly for less experienced surgeons. The CoDIG 2 is a nationwide observational study involving 76 specialized Italian general surgery departments focused on colorectal surgery...

UNLABELLED: Laparoscopic complete mesocolic excision with central vessel ligation has been widely accepted for its oncological benefits in colon cancer surgery. However, laparoscopic right hemicolectomy involves a risk for vascular injury during dissection around the surgical trunk. This technical difficulty has been attributed to the limited movement of conventional laparoscopic forceps. Although robotic devices can overcome the restricted motion of laparoscopic devices, they are not yet widely used...

The modified Graham patch repair is a well-established technique for management of perforating foregut injuries, often learned by surgeons during general surgery training. There is, however, little to no data regarding the utilization of this technique for perforation of the distal midgut or in the re-operative field. We present two cases of midgut anastomotic complications successfully managed with modified graham patch repair at our institution. The first case is a 79-year-old female who underwent an emergent right hemicolectomy at an outside institution for management of an iatrogenic perforation during endoscopic polypectomy...
