Hepatic grooves: An observational study at laparoscopic surgery.

BACKGROUND: In traditional descriptions, the upper surface of the liver is smooth and convex, but deep depressions are variants that are present in 5%-40% of patients. We sought to determine the relationship between surface depressions and the diaphragm. AIM: To use exploratory laparoscopy to determine the relationship between surface depressions and the diaphragm. METHODS: An observational study was performed in all patients undergoing laparoscopic upper gastro-intestinal operations between January 1, 2023 and January 20, 2024. A thirty-degree laparoscope was used to inspect the liver and diaphragm. When surface depressions were present, we recorded patient demographics, presence of diaphragmatic bands, rib protrusions and/or any other source of compression during inspection. RESULTS: Of 394 patients, 343 had normal surface anatomy, and 51 (12.9%) had prominent surface depressions on the liver. There was no significant relationship between the presence of surface depressions and gender nor the presence of rib projections. However, there was significant association between the presence of surface depressions and diaphragmatic muscular bands (P < 0.001). CONCLUSION: With these data, the diaphragmatic-band theory has gained increased importance over other theories for surface depressions. Further studies are warranted using cross sectional imaging to confirm relationships with intersectional planes as well as beta-catenin assays in the affected liver parenchyma.

Whipple's pancreaticoduodenectomy at a resource-poor, low-volume center in Trinidad and Tobago.

BACKGROUND: Many authorities advocate for Whipple's procedures to be performed in high-volume centers, but many patients in poor developing nations cannot access these centers. We sought to determine whether clinical outcomes were acceptable when Whipple's procedures were performed in a low-volume, resource-poor setting in the West Indies. AIM: To study outcomes of Whipple's procedures in a pancreatic unit in the West Indies over an eight-year period from June 1, 2013 to June 30, 2021. METHODS: This was a retrospective study of all patients undergoing Whipple's procedures in a pancreatic unit in the West Indies over an eight-year period from June 1, 2013 to June 30, 2021. RESULTS: This center performed an average of 11.25 procedures per annum. There were 72 patients in the final study population at a mean age of 60.2 years, with 52.7% having American Society of Anesthesiologists scores ≥ III and 54.1% with Eastern Cooperative Oncology Group scores ≥ 2. Open Whipple's procedures were performed in 70 patients and laparoscopic assisted procedures in 2. Portal vein resection/reconstruction was performed in 19 (26.4%) patients. In patients undergoing open procedures there was 367 ± 54.1 min mean operating time, 1394 ± 656.8 mL mean blood loss, 5.24 ± 7.22 d mean intensive care unit stay and 15.1 ± 9.53 d hospitalization. Six (8.3%) patients experienced minor morbidity, 10 (14%) major morbidity and there were 4 (5.5%) deaths. CONCLUSION: This paper adds to the growing body of evidence that volume alone should not be used as a marker of quality for patients requiring Whipple's procedures. Low volume centers in resource poor nations can achieve good short-term outcomes. This is largely due to the process of continuous, adaptive learning by the entire hospital.

Review of minimally invasive pancreas surgery and opinion on its incorporation into low volume and resource poor centres.

Pancreatic surgery has been one of the last areas for the application of minimally invasive surgery (MIS) because there are many factors that make laparoscopic pancreas resections difficult. The concept of service centralization has also limited expertise to a small cadre of high-volume centres in resource rich countries. However, this is not the environment that many surgeons in developing countries work in. These patients often do not have the opportunity to travel to high volume centres for care. Therefore, we sought to review the existing data on MIS for the pancreas and to discuss. In this paper, we review the evolution of MIS on the pancreas and discuss the incorporation of this service into low-volume and resource-poor countries, such as those in the Caribbean. This paper has two parts. First, we performed a literature review evaluating all studies published on laparoscopic and robotic surgery of the pancreas. The data in the Caribbean is examined and we discuss tips for incorporating this operation into resource poor hospital practice. Low pancreatic case volume in the Caribbean, and financial barriers to MIS in general, laparoscopic distal pancreatectomy, enucleation and cystogastrostomy are feasible operations to integrate in to a resource-limited healthcare environment. This is because they can be performed with minimal to no consumables and require an intermediate MIS skillset to complement an open pancreatic surgeon's peri-operative experience.

Clinical outcomes after major hepatectomy are acceptable in low-volume centers in the Caribbean.

BACKGROUND: Major hepatectomies are routinely performed because they are often the only curative treatment for metastatic liver disease. There has been a trend to concentrate major hepatectomies in referral hospitals that perform these operations at high volumes. These high volume referral centers are usually located in developed countries, but many patients in developing nations are not able to access these centers because of financial limitations, lack of social support and/or travel restrictions. Therefore, local hospitals are often the only options many of these patients have for surgical treatment of metastatic liver disease. This is the situation in many Caribbean countries. AIM: To determine the clinical outcomes after major liver resections in a low-resource hepatobiliary center in the Caribbean. METHODS: We prospectively studied all patients who underwent major liver resections over five years. The following data were extracted: patient demographics, diagnoses, ECOG status, operation performed, post-operative morbidity and mortality. Statistical analyses were performed using SPSS ver 16.0. RESULTS: There were 69 major liver resections performed by two teams at a mean case volume of 13.8 major resections/year. Sixty-nine major hepatic resections were performed for: colorectal liver metastases 40 (58%), non-colorectal metastases 9 (13%), hepatocellular carcinoma 8 (11.6%), ruptured adenomas 4 (5.8%), hilar cholangiocarcinomas 4 (5.8%), hemangiomata 2 (2.9%), trauma 1 (1.5%) and hepatoblastoma 1 (1.5%). Twenty-one patients had at least one complication, for an overall morbidity rate of 30.4%. There were minor complications in 17 (24.6%) patients, major complications in 11 (15.9%) patients and 4 (5.8%) deaths. CONCLUSION: There are unique geographic, political and financial limitations to healthcare delivery in the Caribbean. Nevertheless, clinical outcomes are acceptable in the established, low-volume hepatobiliary centers in the Eastern Caribbean.

Modified hanging manoeuvre facilitates inferior vena cava resection and reconstruction during extended right hepatectomy: A technical case report.

Liver resections are safe when performed by specialized hepatobiliary teams. However, complex liver resections are accompanied by significant perioperative risk and they may require modifications of the conventional surgical techniques. We herein report the case of a 54-year-old male patient who underwent an extended right liver resection with en bloc resection and reconstruction of the inferior vena cava. For this complex resection, a modification of the standard operative technique was required. A modified hanging manoeuvre was performed using two 19Fr nasogastric tubes outside the traditional avascular plane to facilitate resection. This modification of the hanging manoeuvre was proven to be feasible and safe, and it is recommended for inclusion in the armamentarium of hepatobiliary surgeons when complex resections are required.

A Management Algorithm for Retained Rectal Foreign Bodies.

Few authors have proposed therapeutic protocols to manage retained rectal foreign bodies (RFBs). All patients with retained RFBs in hospitals across Trinidad and Tobago over 5 years were identified. Hospital records were retrieved and manually reviewed to extract the following data: demographics, history, foreign body retrieved, clinical signs at presentation, management strategy, duration of hospitalization, and morbidity and mortality. There were 10 patients with RFBs over the study period. The annual incidence of this phenomenon was 0.15 per 100,000 population. All patients were men at a mean age of 50.6 years (range: 27-83; SD = 15.3) who presented after a voluntary delay of 1.4 days (range: 0.5-2.5; SD = 0.7). Only one patient gave an accurate history on presentation, but all eventually admitted to self-insertion for sexual gratification. At presentation, one patient had a spontaneous rectal perforation (10%). The remaining nine patients had attempts at bedside transanal extraction, which was unsuccessful in 89% (8/9) of cases. The RFB was pushed beyond the grasp of forceps, making removal under anesthesia unsuccessful in 62.5% (5/8) cases. These patients required more invasive extraction methods including transanal minimally invasive surgery (1), laparoscopic-assisted advancement with transanal retrieval (1), and open surgery with transmural extraction and anastomoses (3). A management algorithm is proposed for the management of RFBs. Important points in this algorithm are the importance of clinician-patient rapport, early surgical referral, avoidance of bedside extraction in the emergency room, early examination under anesthesia, and the inclusion of emerging therapies such as transanal minimally invasive surgery.

Complex liver resections for colorectal metastases: are they safe in the low-volume, resource-poor Caribbean setting?

Introduction. Although many authorities suggest that major liver resections should only be carried out in high-volume specialized centres, many patients in the Caribbean do not have access to these health care systems. Presentation of a Case. A 50-year-old woman with a solitary colorectal metastasis invading the inferior vena cava underwent an extended left hepatectomy with caval resection and reconstruction. Several technical maneuvers were utilized that were suited to the resource-poor environment. Conclusion. We suggest that good outcomes can still be attained in the resource-poor, low-volume centres once dedicated and appropriately trained teams are available.
