Technical Variations and Considerations around OAGB in IFSO-APC and IFSO-MENAC Chapters, an Expert Survey

OBJECTIVE

This study aimed to evaluate the technical variations of one-anastomosis gastric bypass (OAGB) among IFSO-APC and MENAC experts.

BACKGROUND

The multitude of technical variations and patient selection challenges among metabolic and bariatric surgeons worldwide necessitates a heightened awareness of these issues. Understanding different perspectives and viewpoints can empower surgeons performing OAGB to adapt their techniques, leading to improved outcomes and reduced complications.

METHODS

The scientific team of IFSO-APC, consisting of skilled bariatric and metabolic surgeons specializing in OAGB, conducted a confidential online survey. The survey aimed to assess technical variations and considerations related to OAGB within the IFSO-APC and IFSO-MENAC chapters. A total of 85 OAGB experts participated in the survey, providing their responses through a 35-question online format. The survey took place from January 1, 2024, to February 15, 2024.

RESULTS

Most experts do not perform OAGB for children and adolescents younger than 18 years. Most experts create the gastric pouch over a 36-40-F bougie and prefer to create a gastrojejunostomy, at the posterior wall of the gastric pouch. An anti-reflux suture during OAGB is performed in all patients by 51.8% of experts. Most experts set a common limb length of > 4 m in revisional and conversional OAGBs to prevent nutritional complications.

CONCLUSION

The ongoing debate among metabolic and bariatric surgeons regarding the technical variations and patient selection in OAGB remains a significant point of discussion. This survey demonstrated the variations in technical aspects and patient selection for OAGB among MBS surgeons in the IFSO-APC and IFSO-MENAC chapters. Standardizing the OAGB technique is crucial to ensure optimal safety and efficacy in this procedure.

Surgical management in patients with pancreatic cancer: a Queensland perspective

BACKGROUND

Little has been published regarding presenting symptoms, investigations and outcomes for patients with pancreatic cancer in Australia. Data from a series of patients undergoing attempted resection in Queensland, Australia, are presented with the aim of assisting development of consistent strategies in disease management.

METHODS

We reviewed the medical records of 121 patients who underwent attempted surgical resection and who took part in a case-control study between 2007 and 2009. Information relating to symptoms, investigations, surgical procedures and outcomes was captured.

RESULTS

The mean age was 63 years and 60% were men. The most common presenting symptoms were jaundice (64%) and pain (63%). Over 80% of patients had multiple imaging investigations or laparoscopy prior to surgery. Seventy-eight patients (64%) had a completed resection and 23% of these had involved margins. The presence of metastases and/or involvement of vessels or adjacent structures precluded resection in the remaining patients. The 1-year survival for patients whose resections were completed was 77% compared with 51% for those whose tumours were not resectable (P = 0.004). There was no 30-day mortality and 68% of patients were alive 1 year after diagnosis. Resections were performed in 11 different hospitals but over 90% of patients underwent their surgery in one of five high-volume centres.

CONCLUSION

The Queensland experience is consistent with that reported internationally. A significant proportion of attempted resections was not completed because preoperative staging underestimated disease extent. Most patients with potentially resectable disease are being treated in high-volume centres.

Laparoscopic incisional hernia repair with a self-centring suture

BACKGROUND

Open incisional hernia repair is associated with high morbidity and recurrence rates. Laparoscopic approaches offer improved long-term results with low complication rates.

METHODS

Laparoscopic repair was attempted in 117 consecutive patients (median age 68 (range 31-91) years, 50 men) undergoing 122 operations. A novel mesh centralization technique was employed. Data were recorded prospectively. Follow-up was by clinical review or telephone consultation.

RESULTS

One hundred and eighteen procedures (96.7 per cent) were completed laparoscopically; four required conversion. Forty-one patients (35.0 per cent) had additional, unsuspected defects. The median mesh size was 225 (range 42-600) cm2. Median follow-up was 42 months. Small bowel enterotomy occurred in six patients. Fourteen postoperative seromas were successfully aspirated. Recurrence was detected in nine patients (7.7 per cent). One patient was readmitted with small bowel obstruction that settled with conservative management. There were no enterocutaneous fistulas. One patient died after operation from myocardial infarction.

CONCLUSION

Laparoscopic incisional hernia repair using a self-centring suture provides good long-term results with low complication rates.

Cigarette smoking and bladder cancer: an epidemiological inquiry in West Yorkshire

Results are given of a case-control study on bladder cancer in West Yorkshire. The aim of the study was to assess what risks exist for cigarette smoking in the United Kingdom and also to investigate if a dose response effect was present. The study shows for the first time in the United Kingdom a positive but weak relationship between cigarette smoking and bladder cancer. Close examination of the data with regard to this effect shows that a complex set of relationships result when the quantity smoked and the period of smoking are taken into account. A dose response effect is weakly demonstrated when a medium quantity of cigarettes are smoked but it is not present at all in those who smoked most cigarettes for the longest periods. No risk appears to exist for those who have smoked only filter cigarettes. The results are contrasted with similar studies and the significance of the observations are discussed.

ABO, MNSs and rhesus blood groups in bladder cancer

Data are presented on a group of cases of primary carcinoma of the bladder detailing their ABO, MNSs and rhesus blood antigenic phenotypes. Differences, either between all cases and controls or between particular stages of presentation and controls, have been found in the ABO red cell system as well as the MNSs red cell system. In the case of the ABO system an excess of the A gene is present but detailed study shows this to be only in patients with T1 and T2 tumours. No excess was seen in patients with carcinoma in situ or T3 or T4 stage disease. The S gene of the MNSs system is also in excess in cases of bladder cancer.

Ten genetic polymorphisms in bladder cancer

Data are presented on a group of cases of primary carcinoma of the bladder, detailing red cell surface blood group antigenic phenotypes, serum haptoglobin phenotypes, and some red cell isoenzyme phenotypes. Account is taken of the stage of the disease at presentation. The results are compared with corresponding phenotype frequencies in groups of presumed healthy persons originating either in Yorkshire or County Durham. Differences in relative incidences were found in the haptoglobin, phosphoglucomutase (PGM), and some other systems. These are both differences between all cases and controls and between particular stages at presentation and controls.
