Background: Besides laparoscopic pyloromyotomy, the operation for pyloric stenosis has been performed using 2 standard open surgical exposures: the right upper quadrant (RUQ) incision and the semi-circumumbilical (UMB) incision. The aim of this study was to compare the morbidity and cosmetic results of both open exposures.

Methods: Between 1990 and 1995, we performed 104 pyloromyotomies through a RUQ incision. These operations were retrospectively compared with 133 UMB incisions performed between 1995 and 1999.

Results: There were no significant differences between the 2 groups regarding age at presentation, sex, and preoperative status. Only a significantly higher percentage of patients with a metabolic alkalosis before surgery was found in the UMB group, but this did not affect morbidity rate. The groups did not differ significantly with respect to mucosal perforations (P =.95), wound infections (P =.53), inadequate pyloromyotomies (P =.42), or other complications. The mean operating time was slightly longer in the UMB group (P <.025). The UMB approach produced a better cosmetic result, with an almost invisible scar.

Conclusions: This study has shown that the UMB approach has equal intra- and postoperative complication rates as compared with the RUQ approach. The main advantage of the UMB approach is that it produces an excellent long-term cosmetic result.

Article Synopsis
  • The study aimed to compare two surgical incision methods, umbilical (UMB) and right upper quadrant (RUQ), for treating infantile hypertrophic pyloric stenosis (IHPS) in infants.
  • Out of 15 studies involving 2,964 infants, the RUQ incision was associated with shorter operative times and lower rates of complications like wound infections and mucosal perforations compared to the UMB incision.
  • Although UMB incisions create less visible scars, they result in more complications, indicating the need for careful consideration and discussion with caregivers about surgical options; further research is also needed due to the methodological limitations in many of the included studies.

Ultrasound assessment of abdominal adhesions in neonates: data over dogma for re-operative timing.

Pediatr Surg Int

March 2023

Section of Pediatric Surgery, University of Michigan, 1540 E. Hospital Drive, Floor 4 Reception B, Ann Arbor, MI, 48109, USA.

Introduction: Neonatal abdominal reoperation is difficult and can be complicated by abdominal adhesions. Identifying patients who could safely undergo early reoperation would save TPN and central line days, decrease associated infection and liver injury, and NICU and hospital length of stay. We sought to determine if ultrasound (US) could accurately assess the location and severity of adhesions in neonates as an objective dynamic marker capable of informing reoperation timing.

Hepatic hydatid cyst presenting as a cutaneous fistula.

Turk J Emerg Med

February 2020

Department of Surgery, College of Medicine and Health Sciences, UAE University, Al-Ain, United Arab Emirates.

Hepatic hydatid cysts are usually asymptomatic. Nevertheless, they may rupture, causing anaphylactic shock or fistulation. Cutaneous fistulae caused by ruptured hepatic hydatid cysts are extremely rare.

Cholecystocutaneous fistulas (CCFs) are an increasingly rare consequence of chronic gallbladder inflammation and disease. Historically, they were commonly noted in the literature by Courvoisier, Naunyn, and Bonnet in the late 1800s. Due to improvements in diagnostic imaging and treatment options in the last century, there has been a marked decrease in the incidence of the CCF cases in the literature.

Non-laparoscopic minimal surgical approach to pyloromyotomy: An experience from a challenged resource setting.

Afr J Paediatr Surg

September 2017

Division of Pediatric Surgery, Department of Surgery, College of Medicine, King Faisal University, Al Ahsa, KSA.

Background: The aim of the study is to review the experience with the classic Ramstedt's pyloromyotomy through the RUQ approach and the circumlinear supraumbilical fold approach (circumumbilical [CU]) pyloromyotomy (an approach that combines the ease and safety of the open pyloromyotomy with the advantages of minimal invasiveness).

Patients And Methods: A single centre review in a period of 12 years from January 2001 to December 2013 with the institutional ethical committee's approval, evaluating 316 pyloromyotomies based on surgical approach: RUQ (171); and CU (145). Patients' demographics, acid-base/electrolyte status on presentation, mean operative time (MOT), postoperative length of stay (LOS) at hospital, and complications were recorded.
